Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of setting an alarm time and an alarm ringing operation of an electronic timepiece with an alarm.
In particular, the present invention relates to an electronic timepiece with an alarm suitable for setting an alarm time that is relatively close to the current time.

[0002]

2. Description of the Related Art A conventional general electronic timepiece with an alarm has an alarm ringing mode and an alarm non-belling mode. The alarm time remains the same as the time previously set in the alarm regardless of whether the alarm ringing mode or the alarm non-belling mode is set, that is, regardless of whether the alarm ringing is set / reset (on / off). Then, the alarm time set last time was displayed. Further, the alarm is sounded when a certain time has passed after the alarm sounded and the reset alarm time and the current time match.

However, such an electronic timepiece with an alarm is inconvenient when it is desired to set the alarm time relatively close to the current time. That is, when the previously set alarm time is far away from the current time, it takes time to set the alarm time. Therefore, there is a problem in that the work of setting the alarm time is troublesome.

In order to solve this, the applicant of the present application has proposed a technique of setting a time obtained by adding one minute to the current time as an alarm time and displaying the time when the alarm time setting mode is set. (Japanese Patent Application 5-198
603). This makes it possible to realize an electronic timepiece with an alarm that is suitable for setting an alarm time that is relatively close to the current time.

[0005]

However, there are still points to be improved in this technique. That is, in this technique, when the alarm time setting switch is pressed by mistake, the alarm time is set to the time (current time + 1 minute) by this switch input. As a result, an alarm that is not intended to be set is sounded within one minute after the switch is accidentally pressed. Therefore, there are problems that unnecessary noise is generated, the user feels annoyed, and the battery life is shortened due to an increase in current consumption due to an alarm ringing.

Further, in this technique, when the alarm time is subtracted in the alarm time setting mode and coincides with the current time or when the alarm ring is reset (turned off), the alarm time setting mode is suddenly changed. I had switched to another mode. For this reason, there is a problem that the user suddenly changes from the alarm time setting mode, which is difficult to understand in use and the operability is not preferable.

The alarm-equipped electronic timepiece according to the present invention solves the above-mentioned various problems, and in particular, Japanese Patent Application No.
-To further improve the technology described in 198603. Therefore, the main purpose of the present invention is to set the alarm time at a time relatively close to the current time,
The purpose of the present invention is to realize an electronic timepiece with an alarm that can easily set an alarm time and is easy for a user to operate.

Another object of the present invention is to prevent useless alarm ringing even if the alarm time setting mode switch is accidentally pressed.

Still another object of the present invention is to eliminate the uncomfortable feeling of the operator and improve the operability when shifting from the alarm time setting mode to another mode.

[0010]

The electronic timepiece with an alarm of the present invention has an alarm time setting mode for setting an alarm time, and when the alarm time is not set, the alarm time is automatically set to the current time. It is characterized in that it is equipped with unique alarm set / reset means and alarm ringing control means.

Of these, the alarm set / reset means is characterized by the condition of the set / reset.
This alarm setting / resetting means is set when the alarm time setting mode is entered and the alarm time set by the operation of the alarm time setting means based on the switch input does not match the current time. It is when the coincidence detecting means detects. The alarm setting / resetting means is reset when the alarm coincidence detecting means detects a match between the set alarm time and the current time. Further, when the alarm set / reset means is in the reset state, the current time is stored in the alarm time storage means for storing the alarm time (that is, the alarm time and the current time are matched). ) Make up.

Further, in the alarm electronic timepiece of the present invention, when the switch for setting the alarm time is kept pressed in the alarm time setting mode, the alarm time is fast-forwarded and the set alarm time and the current time are displayed. It is characterized in that it has an alarm time setting means for stopping the fast-forwarding of the alarm time when the two coincide with each other.

[0013]

The set / reset state of the alarm set / reset means of the electronic timepiece with alarm of the present invention is summarized as follows.

A) When the alarm time setting mode is entered and an alarm time different from the current time is set by switch input, it is in the set state. In this set state, even when the alarm time setting mode is changed to another mode, the set state remains unchanged. However, in another mode, if the set alarm time and the current time coincide with each other after a lapse of time, an alarm ringing described later is performed to change to the reset state. After that, the reset state is held until the next alarm time setting mode is entered.

B) When the alarm time setting mode is entered and the same alarm time as the current time is set by the switch input, it is in the reset state. This state does not change even when the alarm time setting mode is changed to another mode, and the reset state is maintained.

On the other hand, the alarm ringing control means is characterized by the condition for alarm ringing. That is, the alarm ringing is performed when the alarm coincidence detecting means detects a coincidence between the set alarm time and the current time after the alarm setting / resetting means is set. In other words, after entering the alarm time setting mode and setting an alarm time different from the current time by switch input, if the time has elapsed and the set alarm time matches the current time, the alarm bell will sound. Done. However, it shifts to the alarm time setting mode,
When the set alarm time matches the current time by the switch input instead of the lapse of time, the alarm ringing is not performed even though the time coincidence is detected by the alarm coincidence detection means.

According to the present invention, the alarm ringing is performed as described above. However, as described in A) above, the alarm setting / resetting means sets the alarm state after the alarm ringing. To the reset state. That is, since the alarm ringing is not performed in the reset state, once the alarm ringing is performed, the state automatically switches to the state where the alarm ringing is not performed. The electronic timepiece with an alarm of the present invention is characterized by including such a so-called "one-time alarm". In the prior art, since the set alarm time does not change, the alarm ringing is performed again after a predetermined time has elapsed. And another new operation was required to prohibit this alarm ringing. However, according to the present invention, a new operation is not necessary because the alarm is automatically switched to a state in which it does not sound.

However, the alarm setting / resetting means may not be reset after the alarm ringing. The basis of the present invention is to have a "one-time alarm", but it is also possible to provide a so-called "repeat-type alarm" function that always sounds an alarm at a certain time. That is, a means for selecting whether or not to reset the alarm set / reset means is provided and
Alternatively, it is selected whether to maintain the set state.

The electronic timepiece with alarm of the present invention is
State control having reset time counting means for counting the time during which the alarm setting / resetting means is in a reset state, and setting the alarm time to a non-settable state when the value of the reset time counting means becomes a constant value It is desirable to have a means.

Thus, even if the alarm time setting mode switch is accidentally pressed, useless alarm ringing can be prevented. In other words, although the alarm time setting mode is entered by pressing the alarm time setting mode switch, the alarm setting / resetting means is not set by this alone. Therefore, the alarm ringing is not performed in this state.
If left in this state, the reset time counting means measures the time, and when the value reaches a certain value, the alarm time adjustment mode automatically shifts to another mode (that is, the alarm time is set to It is a state that cannot be set).

Further, in the alarm-equipped electronic timepiece of the present invention, when the switch for setting the alarm time is kept pressed in the alarm time setting mode, the alarm time is fast-forwarded and the set alarm time and the current time are displayed. It has an alarm time setting means for stopping the fast-forwarding of the alarm time when they match.

In this structure, there is provided an input control means for detecting whether or not the switch is operated, and further,
An edge input detection means for detecting whether the switch input detected by the input control means is an edge input, and a push-and-hold input detection means for detecting whether or not the switch input detected by the input control means is a push-and-hold input ing. The alarm time setting means adds (or subtracts) a predetermined unit amount from the alarm time when the edge input detecting means detects an edge input, and the pressing and holding input detecting means detects the pressing and holding input. During the period, the alarm time is fast-forwarded by the fast-forward control means. Further, the alarm time setting means stops the fast forward of the alarm time when the alarm coincidence detecting means detects a match between the set alarm time and the current time.

Therefore, the alarm time to be set is always stopped at the present time during fast-forwarding. If the switch is kept pressed at this time, the alarm time remains stopped. To change the alarm time,
You can stop pressing the switch once and then press it again. That is, the alarm time is set based on the current time, and it is easy to set the alarm time in a time range relatively close to the current time. This is especially effective when the alarm time is set many times. Also,
By combining with the above-mentioned alarm set / reset means that is reset when the set alarm time coincides with the current time, there is an effect that the alarm reset operation becomes very easy.

[0024]

The details of the present invention will be described below with reference to Examples. The basic time in the description and the drawings means the current time measured by the basic clock time measuring means.

First, the overall structure of the electronic timepiece to which the present invention is applied will be described. FIG. 1 is a hardware configuration diagram of an electronic timepiece with an alarm according to the present invention. In the figure, an electronic timepiece is represented by a microcomputer 1 and an LCD panel 1.
0, a switch group 11, and an alarm ringing means 14.

The microcomputer 1 controls the entire electronic timepiece. The oscillator circuit 2 is built in, and the output of the oscillator circuit 2 divided by the divider circuit 3 is used as the system clock φ of the microcomputer 1. Another output of the frequency dividing circuit 3 is input to the interrupt control circuit 4 and used as an interrupt timing signal. The interrupt control circuit 4 controls an interrupt by a microcomputer internal signal and an external signal (not shown), and is connected to the input control circuit 12 and the control circuit 5. The control circuit 5 is a central part for controlling various operations including stopping and starting of the microcomputer 1. This control circuit 5 also controls the alarm time setting, which is a feature of the present invention.
Is.

The control circuit 5 described above, the ROM 6 in which the program for controlling the operation of the electronic timepiece is stored, the RAM 7 for storing various data required during the operation of the electronic timepiece,
The display control circuit 9 for controlling the display related to the clock, the input control circuit 12 for monitoring the state of the switch group 11 and controlling the switch input, and the alarm control circuit 14 for controlling the ringing of the alarm ringing means 13 are connected via the internal bus 15. Are connected to each other. The alarm bell 14 used in this embodiment is a piezoelectric buzzer. However, the alarm ringing means is not limited to this. For example, there is no particular limitation as long as it vibrates at a predetermined vibration frequency to notify the operator, such as an acoustic speaker, a bell, a tuning fork, and a vibrator.

Further, since the frequency dividing circuit 3 is also connected to the internal bus 15, the state of the frequency dividing circuit 3 can be read out by a program. Further, since the interrupt control circuit 4 is also connected to the internal bus 15, it is possible to set an interrupt condition and read an interrupt factor by a program. An alarm time memory 8 as an alarm time storage means is provided in a part of the RAM 7. However, the alarm time memory 8 is RAM 7
It does not have to be provided inside, but may be an independent memory or register, or a non-volatile RA
It may be provided in M.

Next, the display panel 10 and the switch group 11 will be described. FIG. 2 is a conceptual diagram showing the external appearance of one embodiment of the electronic timepiece with alarm of the present invention. This figure shows a state in which the alarm time is set in the alarm time setting mode. In the figure, the LCD panel 10 arranged in the center of the front of the main body 20 is indicated by the current time display area 16
Is divided into an alarm time display area 17. In the current time display area 16, the current time is always displayed in hours, minutes and seconds. In the alarm time setting mode, the alarm time display area 17 displays a time corresponding to the operation of the switch group 11 (this will be described later). After the alarm time is once set, the set alarm time is continuously displayed until the alarm rings, even in the basic clock mode (not in the alarm time setting mode).

On the other hand, in the basic clock mode (when the alarm time setting mode is not set) and no alarm time is set, the same value as the hour and minute of the current time is displayed. Is configured to. That is, in this case, the alarm time is displayed so as to automatically follow the current time.

There is another method for displaying the alarm time. For example, the alarm time may not be displayed in the normal basic clock mode, but the alarm time may be displayed only in the state of the alarm time setting mode described later. This is because, in the case of the present embodiment, in the basic clock mode and the alarm time is not set, the alarm time and the current time are the same, so there is no need to display duplicate time information. Because there is no. Further, although the present embodiment has two display areas, that is, the current time display area 16 and the alarm time display area 17, this display area may be one. That is, the current time may be displayed in the normal basic clock mode, and the alarm time may be displayed instead of the current time in the alarm time setting mode. In this case, in the alarm time setting mode, it is desirable to turn off the display in units of seconds. In actual setting of the alarm time, setting in seconds is not necessary so much, and by turning off the display in seconds, it becomes easy to distinguish between the current time display and the alarm time display.

Further, in the present embodiment, the LCD panel is used as the display means, but it is not limited to this, for example, a light emitting diode (LED), an electroluminescence element, a fluorescent display tube, a discharge tube, an incandescent lamp, a non-illuminating lamp. It may be a light emitting numeric display plate or the like. Further, although the case of digital display is shown in the present embodiment, it is of course possible to use analog display.

The switch group 11 is composed of a first external operation switch 18 and a second external operation switch 19 which are push button type switches. When any one of the external operation switches of the switch group 11 is pressed, the alarm time setting mode is entered. Then, the first external operation switch 1
When 8 is pressed, the alarm time is set to (current time + 1 minute) and is displayed in the alarm time display area 17, and when the second external operation switch 19 is pressed, the alarm time is (current time-1 Minute) and is displayed in the alarm time display area 17. Further, at this time, an alarm setting mark 21 indicating that the alarm bell is set is displayed in the alarm time display area 17.
The alarm setting mark 21 is turned off when the alarm ring is reset.

Although the first external operation switch 18 and the second external operation switch 19 are formed on the side surface of the main body 20,
There is no particular restriction on the arrangement as long as it does not hinder the operation. However, in general, the side surface of the main body 20 is easier to operate than the surface of the main body 20 on which the LCD panel is located (the surface on which the display portion is located). However, if the area of the display unit (LCD panel) is sufficiently large, a switch may be provided in the display unit.

In this embodiment, the push type switch is used as the switch, but the switch is not limited to this. For example, a slide type switch or a touch type switch can be applied. In particular, the touch type switch is optimal when the switch is arranged on the display unit.

Now, the operation of the embodiment of the electronic timepiece with alarm of the present invention will be described with reference to the flow chart.

FIG. 3 is a block diagram showing a first embodiment of an electronic timepiece with an alarm according to the present invention. In the figure, a basic clock timing means 101 has a clock function as a clock.
Is. The information (current time) measured by the basic clock time measuring means 101 is displayed in the current time display area 16 shown in FIG. The timekeeping information is also sent to the alarm time gate 108 and the alarm coincidence detecting means 104.

The alarm time setting means 1 is stored in the alarm time storage means 103 (alarm time memory 8 shown in FIG. 1).
Either the arbitrary alarm time set by 02 or the time information (current time) of the basic clock time measuring means 101 through the alarm time gate 108 is stored. The alarm time setting means 102 is configured such that the alarm time is set by the input switch (the first external operation switch 18 or the second external operation switch 19 shown in FIG. 2). Further, from the alarm time setting means 102, an alarm time setting mode signal (a signal indicating that the cause of generation of the time coincidence detection signal by the alarm coincidence detection means 104 described later is due to the operation of the alarm time setting means 102). Is output. The information stored in the alarm time storage means 103 is displayed in the alarm time display area 17 shown in FIG. 2 via the display control circuit 9 shown in FIG.

The alarm time storage means 103 is connected to the alarm coincidence detection means 104. The alarm coincidence detection means 104 is the alarm time storage means 1
It is detected whether or not the alarm time stored in 03 and the current time by the basic clock timing means 101 match.

The alarm set / reset means 106 receives the output of the alarm coincidence detection means 104 (time coincidence detection signal) and the output signal of the alarm time setting means 102 (alarm time setting mode signal). The output of the alarm coincidence detection means 104 (time coincidence detection signal) and the set signal indicating the set state of the alarm setting / resetting means 106 are the alarm bell 1
It has been input to 09. Then, when the alarm time setting mode signal is output from the alarm time setting means 102 and the time coincidence detection signal is not output from the alarm coincidence detection means 104 (the set alarm time is different from the current time). In the case), the alarm setting / resetting means 106 is set. Then, this set state is maintained as it is even if the alarm time setting mode signal is not output. After that, when the alarm coincidence detecting means 104 detects the coincidence between the alarm time and the current time due to the passage of time, the alarm bell gate 109 opens. As a result, the alarm ringing control means 105 operates, and the alarm ringing means 107 is driven for a predetermined time to perform the alarm ringing. Then, the alarm setting / resetting means 106 changes from the set state to the reset state. The alarm setting / resetting means 106
When the is set, the alarm setting mark 2 shown in Fig. 2
1 is configured to be turned on (in contrast,
It is off during the reset state).

Now, the alarm setting / resetting means 10
When 6 is not in the set state, it always holds the reset state. When the alarm setting / resetting means 106 is reset, a reset signal is sent to the alarm time gate 108. As a result, the alarm time gate 108 opens and the information (current time) measured by the basic clock time measuring means 101 is stored in the alarm time storage means 103. By this operation, the alarm time automatically follows the current time.

Next, the operation of the above block diagram (FIG. 3) will be described in more detail with reference to the flow charts shown in FIGS. The symbol "AL" in the figure is an abbreviation for an alarm.

The flowchart shown in FIG. 4 is a basic program which operates when the interrupt control circuit 4 shown in FIG. 1 generates a 1 Hz interrupt. That is, it is a program executed every one second. First, the basic timekeeping means 101 shown in FIG. 3 measures the basic time (step 201), and it is determined whether the basic time is 0 seconds, that is, whether the counting of minute digits occurs (step 20).
2). At this time, if the basic time is 0 second, it is determined whether the alarm is in the set state (whether the alarm set / reset means 106 is in the set state) (step 203).
If it is in the alarm set state, a match between the alarm time and the basic time is detected (step 205), and if they match, an alarm is sounded (step 206).

On the other hand, if it is determined in step 203 that the alarm is not set (the alarm setting / resetting means 106 is in the reset state), the basic time is stored in the alarm time memory 8 shown in FIG. The basic time is set (step 204). Therefore, in the alarm reset state, the alarm becomes the same time as the basic time,
The count is similarly incremented as the basic time is incremented.

FIG. 5 is a flow chart showing the operation in the alarm time setting mode. First, in the basic clock mode, when the input of the switch for adding or subtracting the alarm time (the first external operation switch 18 or the second external operation switch 19 shown in FIG. 2) is detected (step 3
01) Move to alarm time setting mode. Then, the alarm time is added or subtracted according to the input switch (step 302). In this embodiment, the amount of addition and subtraction is set to 1 minute. Of course, it is not limited to 1 minute units,
For example, it can be applied by appropriately changing it in units of 10 minutes, 1 hour, or 2 seconds. Now, next, the coincidence between the alarm time and the basic time is detected (step 303), and if they coincide with each other, the alarm set / reset means 106 is set to the reset state (step 305). On the other hand, if they do not match, the alarm setting / resetting means 106 is set (step 304). And step 3
In either case of 04 or step 305, the flow shifts from the alarm time setting mode to the basic clock mode, and this flow ends.

Therefore, for example, the alarm time is now 7:59.
Then, assuming that the basic time is 8:00, the alarm is reset when the addition switch (first external operation switch 18) is pressed and the alarm time becomes 8:00.
If you leave it as it is, according to the flowchart in Figure 4,
If the basic time is 8:01, the alarm time is also 8:01, and if the basic time is 8:02, the alarm time is 8:
It becomes 02. Both basic time and alarm time are 8:02
If the addition switch is input again and the alarm time becomes 8:03, the alarm will be set, and if left as it is, the alarm will ring when the basic time becomes 8:03 according to the flowchart in FIG. Done.

Next, a modification of the first embodiment of the present invention will be described. This relates to the alarm ringing time control, the halfway stop of the alarm ringing, and the reset operation of the alarm set / reset means based on this alarm ringing control.

FIG. 6 is a block diagram showing a modification of the first embodiment of the present invention. In the figure, the basic clock timing means 101, the alarm time setting means 102, the alarm time storage means 103, the alarm coincidence detection means 104, the alarm ringing means 107, the alarm time gate 108, and the alarm ringing gate 109 are the above-mentioned first. Since the function and the configuration are the same as those of the embodiment, the description thereof will be omitted.

Now, the alarm setting / resetting means 40
6 is set and the alarm coincidence detection means 10
When the time coincidence detection signal is output from 4, the alarm ringing gate 109 is opened and the alarm ringing is performed. At this time, the alarm bell control means 405 controls the operation of the alarm bell means 107. In the case of the present embodiment, the alarm ringing time counting means 408 and the input control means 409 are connected to the alarm ringing control means 405. The alarm ringing time counting means 408 serves as a time counter for determining the alarm ringing time. Further, the input control means 409 outputs an instruction signal for stopping the alarm ringing by detecting the input of an alarm ringing switch (not shown). Therefore, the alarm ringing control means 405 outputs an alarm when the time set by the alarm ringing time counting means 408 has elapsed or when the input control means 409 detects that the alarm ringing switch has been input. Stop ringing. further,
The alarm ringing control unit 405 receives the stoppage of the alarm ringing and outputs a signal for resetting the alarm set / reset unit 406 to the alarm set / reset unit 40.
Send to 6.

Next, the operation of the above block diagram (FIG. 6) will be described in more detail with reference to the flowcharts shown in FIGS. 7 and 8. The symbol "AL" in the figure is an abbreviation for an alarm.

FIG. 7 is a flow chart for explaining the operation of the alarm ringing time counting means 408. And
Similar to the program shown in the flowchart of FIG. 4, this is a program that operates when a 1 Hz interrupt is generated by the interrupt control circuit 4 of FIG. That is, it is a program executed every one second. First, the basic timekeeping means 101 shown in FIG. 6 measures the basic time (step 5).
01), it is determined whether or not the basic time is 0 second, that is, whether or not minute digits have been counted (step 502). At this time, if the basic time is 0 second, it is determined whether the alarm is set (whether the alarm setting / resetting means 106 is set) (step 503). If it is in the alarm set state, the coincidence between the alarm time and the basic time is detected (step 505), and if they coincide, the alarm is sounded (step 506).

On the other hand, if it is determined in step 503 that the alarm is not set (the alarm setting / resetting means 106 is in the reset state), the basic time is stored in the alarm time memory 8 shown in FIG. The basic time is set (step 504). The process up to this point is the same as the flowchart shown in FIG.

Now, returning to step 506 again, after the alarm ringing is performed in step 506, the parameter N for alarm ringing time counting is set to 0 (step 507).
This N is a parameter that determines the alarm ringing time.

On the other hand, if it is determined in step 502 that the basic time is not 0 second and the alarm is ringing (step 508), the alarm ringing time counting parameter N is added (step 509). When N reaches a constant value, for example, 20 (step 510), the alarm ringing is stopped (step 511). Further, a signal is sent to the alarm setting / resetting means 106 shown in FIG. 6 to bring it into an alarm reset state (step 512).

Here, the alarm ringing time is set to 20 seconds, but of course any value can be selected as this value. However, it is necessary to devise when sounding the alarm for more than 1 minute. That is, the alarm ringing time is 1
If it is less than a minute, the alarm time and the basic time always match when the alarm ringing is stopped.
If it is more than a minute, the alarm time and the basic time will be different (the basic time will be the alarm time + 1 minute). Therefore, in such a case, after the alarm reset in step 512, the basic time is copied to the alarm time memory 8,
Performs processing with the alarm time as the basic time. That is,
The same processing as step 504 will be performed.

By slightly modifying the flowchart shown in FIG. 7, the alarm ringing can be performed for a long time. The two methods will be briefly described below.

First, the first method incorporates between step 501 and step 502 a step of determining whether an alarm is sounding. If the alarm is not sounding, the routine proceeds to step 502, and if the basic time is not 0 second, this routine is ended. If the alarm is sounding, the process proceeds to step 509. In this case, the set count value in step 510 is made larger than 20 (for example, 100, 200, etc.).

The second method incorporates a step between step 502 and step 503 for determining whether or not the alarm is sounding (in this case, if the basic time is not 0 second in step 502, this routine is terminated). To). If the alarm is not ringing, step 503
Proceed to. If the alarm is ringing, step 509
Thereafter, the routine proceeds to step 512. In this case, the alarm ringing time can be set in units of 1 minute (that is, if the set count value is 5 in step 510, the alarm ringing is performed for 5 minutes).

Next, the case where the alarm ringing is stopped not only by the alarm ringing time but also by the switch input will be described. FIG. 8 is a flow chart for explaining the operation of the input control means 409.

First, it is judged whether or not there is a switch input (not shown) (step 601), and if there is a switch input, it is judged whether or not an alarm is sounding (step 6).
02). If the alarm is sounding, the alarm is stopped (step 603) and the alarm is reset (step 604). Similar to the operation shown in the flow chart of FIG. 7, if the alarm ringing time is less than 1 minute, the alarm time and the basic clock time always match when the alarm ringing is stopped, so that it is possible to leave it as it is for 1 minute or more In this case, after step 604, the basic time is copied to the alarm time memory 8 and the alarm time is set as the basic time.

As the switch used in this embodiment,
The first external operation switch 18 or the second external operation switch 19 shown in FIG. 2 is suitable. These switches are originally used to set the alarm time, but since it is not necessary to set the alarm time during the alarm ringing, they can be used as switches for stopping the alarm ringing. Also, either one or both of these switches may be used to stop the alarm ringing. Of course, a switch other than the first external operation switch 18 or the second external operation switch 19 may be provided.

Next, another modification of the first embodiment of the present invention will be briefly described. This is to select whether or not the reset operation of the alarm set / reset means is performed after the alarm ringing.

In the first embodiment shown in FIG. 3, the alarm setting / resetting means 1 is performed after the alarm ringing.
06 had changed to the reset state. As a result, the alarm will not ring unless a new alarm time is set. The alarm time automatically follows the basic time. That is, it constitutes a "one-time alarm".

On the other hand, it is conceivable that the alarm setting / resetting means 106 is not reset after the alarm ringing. In this case, the alarm set /
Since the reset means 106 maintains the set state,
The alarm time does not follow the basic time and remains the same as the already set alarm time. Therefore, the alarm ringing is performed again after a predetermined time has elapsed. That is, "
Repeat type alarm ”can be configured.

This modification is a "one-time alarm".
And "repeat type alarm" are configured so that the operator (user) can select them. This mechanism will be briefly described. In the block diagram shown in FIG.
A selection means for controlling whether or not to reset the alarm set / reset means 106 is newly provided, and the output of this selection means is configured to control the reset operation of the alarm set / reset means 106. The selecting means is controlled by an input of an external operation switch (not shown) so that the operator can operate (that is, whether or not to reset the alarm setting / resetting means 106 can be selected). As the external operation switch, the first external operation switch 18 or the second external operation switch 19 described above may be used, or another switch may be newly provided.

The series of controls can be realized by software. Specifically, for example, in the flowchart shown in FIG. 7, the alarm reset in step 512 is changed. Insert a routine that determines whether or not an alarm reset should be performed instead of always performing an alarm reset. For example, when the switch input is detected by an external operation switch or the like, the alarm reset may not be performed, and if the switch input is not detected, the alarm reset may be performed.

By doing so, it is possible to set two different alarms according to the intention of the operator. Further, the alarm ringing mode may be changed between the "one-time alarm" and the "repeat alarm". That is, the ringing pattern, such as the alarm ringing interval and ringing length, the alarm ringing sound frequency, etc. are changed. This allows for "one-time alarms" and "
Since the alarm ringing state is different for "Repeat type alarm", it is easy to distinguish them.

Now, the operation of the second embodiment of the electronic timepiece with alarm of the present invention will be described with reference to the block diagram of FIG. 9 and the flow charts of FIGS. 10 and 11.
The present embodiment is characterized by the operation in the alarm time setting mode, and particularly controls the operation in the alarm time setting mode by measuring the time during which the alarm set / reset means is reset.

FIG. 9 is a block diagram showing a second embodiment of the electronic timepiece with an alarm according to the present invention. In the figure, a basic clock timing means 101, an alarm time storage means 103,
Alarm coincidence detection means 104, alarm ringing control means 1
05, the alarm setting / resetting means 106, the alarm ringing means 107, the alarm time gate 108, and the alarm ringing gate 109 have the same functions and configurations as those of the first embodiment described above, and therefore the description thereof will be omitted.

Now, the alarm time setting means 7 of this embodiment
03 performs a two-step operation of shifting from the basic clock mode (second mode) to the alarm time setting mode (first mode) and setting the alarm time. When the alarm setting / resetting means 106 is in the reset state, the reset period counting means 701 measures the time. When the reset period counting means 701 measures a constant value, the mode control means 702 causes
The command for changing the state of the electronic timepiece from the alarm time setting mode to the basic timepiece mode is the alarm time setting means 70.
Sent to 3. Thereby, the alarm time setting means 70
It becomes impossible to set the alarm time by 3.

The operation of this block diagram will be described in detail below with reference to the flow charts of FIGS.

FIG. 10 is a flow chart showing the operation when shifting from the basic clock mode to the alarm time setting mode. It is now in the basic clock mode, and it is assumed that the alarm time setting mode switch is entered from this mode to the alarm time setting mode. As this switch, it is preferable to use either the first external operation switch 18 or the second external operation switch 19 described above. However, another switch may be newly provided.

Now, in the basic timepiece mode (step 801), when it is detected that the alarm setting mode switch is input (step 802), the mode of the electronic timepiece shifts to the alarm time setting mode (step 80).
3). Then, the parameter k for measuring time is reset to 0 (step 804). However, at this time, the alarm setting / resetting means 106 does not change while maintaining the previous state. Therefore, if the alarm setting mode switch is operated only once, the alarm setting mark 21
Is not displayed, and the alarm time does not change. (If the alarm time is not set, the alarm time remains the same as the basic time, and if the alarm time is set, the set alarm time is displayed. ing).

When the switch is further operated in this state, the alarm setting mark 21 is displayed, and the alarm time also changes. If the first external operation switch 18 is operated, the alarm time is incremented by +1 minute, and if the second external operation switch 19 is operated, the alarm time is reduced by -1 minute. Then, the alarm setting / resetting means 106 is set. That is, the alarm time can be set by operating the switch twice.

Next, FIG. 11 shows the operation when shifting from the alarm time setting mode to the basic clock mode. The program based on this flowchart operates when the 1 Hz interrupt is generated by the interrupt control circuit 4 shown in FIG.

First, the basic time is measured (step 90
1) It is determined whether the basic time is 0 second, that is, whether the counting of minute digits has occurred (step 902). If the basic time is not 0 seconds, the process ends without doing anything. Then, if the basic time is 0 second, it is determined whether or not the alarm is set (step 903). The alarm set state is a state in which the alarm set / reset means 106 is set. If it is in the alarm set state, k is reset to 0 (step 904) and the coincidence between the alarm time and the basic time is detected (step 905). If they match, an alarm is sounded (step 906).

On the other hand, if it is determined in step 903 that the alarm is not set (alarm is reset), the basic time is copied to the alarm time memory and the alarm time is set as the basic time (step 907). Therefore, in the alarm reset state, the alarm has the same time as the basic time and counts up as the basic time counts up. Furthermore, if it is the alarm time setting mode (step 908), k is incremented by 1 (step 90).
9) If k is 3, k is reset to 0 (step 91
0), the mode shifts to the basic clock mode (step 91).
2).

Therefore, according to FIGS. 9 to 11, the alarm reset state continues when only the alarm time setting mode is entered. Then, if the switch is not operated as it is, the mode automatically returns to the basic clock mode after a few minutes. For this reason, the alarm ringing does not occur even if the alarm time setting mode switch is operated only once, and the basic clock mode is returned after a predetermined time. Therefore, even if the switch is mistakenly operated, an unnecessary alarm ringing may occur. Absent.

There are other methods than the above as a method of operating the alarm time setting mode switch. The above method allows the alarm time to be set by two intermittent operations, but it is a method of performing this by one operation.

This method will be briefly described. First,
The alarm time setting mode switches to the alarm time setting mode at the moment the switch is operated. Of course, at this time, the alarm setting / resetting means 106 keeps the previous state, and the alarm ringing is not performed immediately. Therefore, the state where the switch is operated is kept as it is. When this state continues for a predetermined time (for example, about 2 seconds), the alarm time is added (or subtracted) according to the operated switch, and the alarm set state is set. That is, the state shifts to a state where the alarm time can be set. According to this method, the alarm time can be set by one operation. Usually, it is often the case that the switch is operated erroneously for a short time (generally within 1 second). Therefore, this method can be distinguished from the case where the switch is operated erroneously.

In the second embodiment described above,
The basic clock mode has been described as an example of the mode (second mode) in which the alarm time cannot be set.
Of course, this mode is not limited. For example,
Basic clock time setting mode (for example, time difference setting or summer time setting), environmental data measurement mode (temperature /
Humidity, atmospheric pressure, wind speed, water pressure, direction, acceleration (motion state)
UV amount, radiation dose, illuminance, electric field strength, magnetic field strength, gas detection, etc.), diving mode (mode that handles information related to diving operations such as water depth, dive time, possible dive time / depth, remaining air amount), data Various modes such as analysis mode (mode to select / convert / calculate / display / store collected data), communication mode (mode to exchange data with other device than electronic watch) May be

Now, the block diagram of FIG. 12 and FIG. 13 of the third embodiment of the electronic timepiece with alarm of the present invention will be described.
The flowchart will be described with reference to the timing chart of FIG. The present embodiment is characterized by the alarm time setting method in the alarm time setting mode, and in particular,
It relates to the control method of the time fast-forward control means.

FIG. 12 is a block diagram of a third embodiment of an electronic timepiece with an alarm according to the present invention. In the figure, whether or not the switch 1001 is operated (whether or not there is a switch input) is detected by the input control means 1002. As the switch used here, the above-mentioned first external operation switch 18 or second external operation switch 19 is suitable.

The detected switch input is further detected by the edge input detection means 1003 depending on whether the switch input is the edge input or not.
Detects whether or not the input is continued by pressing. If it is an edge input, the alarm time stored in the alarm time storage means 1007 via the alarm time setting means 1005 connected to the edge input detection means 1003 is incremented by 1 minute or decremented by 1 minute. Then call). Whether to add or subtract depends on the operated switch. Further, the unit amount to be added and subtracted is not limited to 1 minute, and for example, 10 seconds, 2 minutes, 5 minutes, 10 minutes,
It is possible to adopt an arbitrary value such as 1 hour.

On the other hand, when the pressing-and-holding input detecting means 1004 detects that the pressing-and-holding input is made, the alarm setting alarm time storage means 1 is sent via the fast-forwarding control means 1006 connected to the pressing-and-holding input detecting means 1004.
Fast-forward addition or subtraction is performed on the alarm time stored in 007. The alarm coincidence detection means 1008 connected to the alarm time storage means 1007 compares the set alarm time with the contents of the basic clock timekeeping means 1009, that is, the basic time, and if they match, the fast-forward control means 1006.
To stop the fast forward of the alarm time.

The operation of the above block diagram will be described with reference to the flowchart of FIG. In the case of this embodiment, when the switch input continues for 1 to 2 seconds, the alarm time fast-forward processing is performed by adding / subtracting 1 minute every 8 Hz. In other words, after 1-2 seconds have passed since the switch was continuously operated, the fast-forward period starts, and thereafter, 1 / 8th every 1 second.
The alarm time is added (or subtracted) in units of minutes, that is, the alarm time is added (or subtracted) by 8 minutes in one second. Therefore, this program needs to be repeatedly operated at a cycle of 1/8 second or less. In this embodiment, it is configured to operate every 16 Hz. The time from when the switch input is detected until the fast-forward period is reached varies in the range of 1 to 2 seconds, but this is due to the variation in the timing of starting the switch operation.

When the input of the switch for adding or subtracting the alarm time is detected (step 1101), it is first determined whether the input is an edge input (step 1102). If it is an edge input, one minute is unconditionally added or subtracted by one minute according to the input switch (step 1103), and the counter value K for fast-forward processing is reset to 0 (step 1104). That is, ± 1 minute is added or subtracted at the moment the switch is operated.

On the other hand, if the input is not an edge input, it is determined that the input is continued pressing, and the alarm time is compared with the basic clock time (step 1105). If they match, the program ends. If they do not match, the fast-forward control processing of steps 1106 to 1109 is performed. First, it is determined whether it is the falling timing of the 1 Hz signal (step 1106), if it is the falling timing, the counter value K is incremented by 1 (step 1107), and if not, it is determined whether the counter value K is 2 or more. (Step 1108). When the counter value K is 2 or less, the program is terminated as it is, and when it is 2 or more, it is further determined whether or not the 8 Hz signal is L, and when it is L, the alarm time is added or subtracted by 1 minute (step 1110).

This will be specifically described with reference to the timing chart of FIG. Now, it is assumed that the basic clock time is 8:04 and the alarm time is 8:00. If the addition switch is input (timing a), switch detection (step 110)
1), determination of edge input (step 1102)
1 minute is added to the alarm time (step 110
3) becomes 8:01. The counter value K is reset (step 1104) and K = 0.

At the next program operation timing b, after detecting the switch (step 1101) and judging whether it is an edge input (step 1102), it is judged whether the alarm time coincides with the basic clock time (step 11).
05). Now, the alarm time is 8:01, the basic time is 8:04, and both times do not match, so
Next, it is determined whether or not it is the falling timing of the 1 Hz signal (step 1106). In this case, the counter value K is incremented by 1 because it is the falling timing of the 1 Hz signal (step 1107), and it is further determined whether the K value is 2 or more (step 1108). In this case, the counter value is K = 1 and is less than 2, so the program ends.

At the next program operation timing c, after detecting the switch (step 1101) and determining whether it is an edge input (step 1102), it is determined whether the alarm time matches the basic clock time (step 11).
05). This time as well, the alarm time is 8:01 and the basic clock time is 8:04, so they do not match.
It is determined whether it is the falling timing of the Hz signal (step 1106). This time, since it is not the falling timing of the 1 Hz signal, it is judged whether the K value is 2 or more with the counter value K as it is (step 1108). Since the counter value is K = 1 and it is less than 2, the program ends. Therefore, the alarm time and the counter value do not change.

After the operation similar to the timing c is repeated 14 times, at the next program operation timing d, after the switch detection (step 1101) and the edge input determination (step 1102), the alarm time becomes equal to the basic clock time. Judge whether or not (step 110)
5). The alarm time is still 8:01, the basic clock time is 8:04, and they do not match.
It is determined whether it is the signal falling timing (step 1106). Since this time is the falling timing of the 1 Hz signal, the counter value K is incremented by 1 (step 1107),
Further, it is judged whether the K value is 2 or more (step 110).
8) Since the counter value is K = 2, it is determined whether the signal is an 8 Hz signal or L (step 1109). In this case, since the 8 Hz signal is L, the alarm time is added by 1 minute (step 11
10), the program ends at 8:02.

At the next program operation timing e, 8
Since the Hz signal is not L, the program ends as it is.

At the next program operation timing f, 8
Since the Hz signal is L, the alarm time is added by 1 minute (step 1110), and the program ends at 8:03.

When the same operation as the program operation timing e is performed at the program operation timing e ′ and the same operation as the program operation timing f is performed at the program operation timing f ′, the alarm time is the same as the basic clock time 8: Will be 04. Then, at the next program operation timing g, after detecting the switch (step 1101), determining whether it is an edge input (step 1102), and determining whether the alarm time coincides with the basic clock time (step 1105), the alarm time is 8 : 04, the basic time is also 8:04, and both times match, so the program ends as it is. Then, as long as the addition switch is input thereafter, the operation at the program operation timing g is repeated. That is, the alarm time does not change even if the switch is continuously operated. However, if the basic time advances by one minute in the middle, the basic time and the alarm time do not match at that time, so the same operation as the program operation timing d is performed, and the alarm time is also added by one minute. Therefore, the alarm time follows the basic time.

Now, suppose that the operation of the addition switch is stopped in this state (the state of both the basic time and the alarm time is 8:04). Then, it is detected that the addition switch is released at the program operation timing h. When the addition switch is operated again after a while, the program operation timing i
Then, similarly to the program operation timing a, the alarm time is incremented by 1 minute (step 1104) after the switch detection (step 1101) and the determination as to whether or not the edge is input (step 1102), resulting in 8:05. Counter value K
Is reset (step 1104) and K = 0.
After that, the program operation timings b, c, d, e, f,
g The same operation is performed.

With the above configuration, even if the alarm time is fast forwarded, the alarm always stops at the current time. That is, when setting an alarm time that is relatively close to the current time, the current time can be used as a reference, which makes it extremely easy to set the alarm time. Especially, this method is effective when the alarm time is set many times.

In this embodiment, the count value K
Although it is configured to perform fast-forwarding when = 2 or more, the present invention is not limited to this. Considering the operability of the operator, the preferable range of K for shifting to the fast-forward is 1 ≦ K ≦ 3. Also, for fast-forwarding, a signal of 8 Hz was used (that is, 8 units are added / subtracted in 1 second).
A preferable range is about 4 to 64 Hz.

Further, the third embodiment and the first embodiment may be combined. In this case, the alarm setting / resetting means shown in the first embodiment can be easily reset. That is, in the alarm time setting mode, the alarm time is reset by matching the alarm time with the current time. This is useful in avoiding alarm ringing.

Incidentally, in the above-mentioned embodiment, various means (for example, the basic clock timing means 1) as the constituent elements thereof.
01, alarm time setting means 102, alarm time storing means 103, alarm coincidence detecting means 104, alarm setting / resetting means 106, etc.) are realized by software programs, but these are realized by hardware. It is self-evident to fulfill the function of.
