Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a circuit configuration diagram of a multifunctional electronic timepiece according to an embodiment.

In FIG. 1, the reference clock signal generated by the oscillation circuit 1 is divided by the frequency dividing circuit 2, and a 1 Hz clock signal is output to the time counting circuit 3 and the AND gate 4.
The 00 Hz signal is output to AND gate 5. The time counting circuit 3 counts 1 Hz clock signals to obtain time data,
The time data is output to the CPU 6.

Flip-flop (hereinafter referred to as FF) 7
Is a circuit which is set or reset by a set signal and a reset signal from the CPU 6, and when the FF 7 is in a set state (output Q is “1”), a 100 Hz signal is supplied to the stopwatch counting circuit 9 through the AND gate 5. Then, when the FF 7 is reset (the output Q is "0"), the AND gate 5 is closed and the supply of the 100 Hz signal to the stopwatch circuit 9 is stopped.

The stopwatch counting circuit 9 includes the above 10
It is a circuit that counts 0 Hz signals and measures the elapsed time from the start of measurement to the present, and outputs the measured stopwatch time data to the CPU 6.

The FF8 is a circuit which is set or reset by a set signal and a reset signal from the CPU 6, and when the FF8 is in a set state, a 1 Hz signal is supplied to the subtraction timer circuit 10 via the AND gate 4, and the FF is fed.
When 8 is reset, supply of the 1 Hz signal to the subtraction timer 10 is stopped.

The subtraction timer 10 is a circuit for subtracting the elapsed time from the start obtained by counting the 1 Hz signal from the preset timer time, and outputs the subtraction result to the CPU 6 as timer time data.

Further, the stopwatch counting circuit 9,
The subtraction timer circuit 10 is configured such that the count content is reset by a reset signal from the CPU 6. The alarm time storage circuit 11 is a circuit for storing the alarm time set by the user, and outputs the stored alarm time to the CPU 6.

The CPU 6 detects the operation signal of the switch of the switch section 12 and sets or resets the FF 7 and FF 8 to start the stopwatch time measurement or the timer time measurement, and the time counting circuit 8 and the stopwatch counting circuit 9 The data output from the subtraction timer circuit 10 and the alarm time storage circuit 11 are stored in the RAM 13. Further, the CPU 6 displays various data such as the current time, stopwatch time, timer time, and schedule on the display unit 14.

Although not shown, the switch section 12 is a mode changeover switch S1 operated when switching operation modes such as a current time mode, a schedule mode, and a stopwatch mode, and a switch S2 operated when starting or stopping the stopwatch measurement. When,
S3 switch operated when starting or stopping timer measurement, and S operated when setting the timer time
4, S5 switch.

Further, in the RAM 13, as shown in FIG. 1, the mode register M and the timer time, which is set when the timer time is set, is displayed for displaying the timer time which is set for a certain time in the display processing described later. A flag FH and the like are provided.

The mode flag M stores a numerical value corresponding to the operation mode. For example, in the current time mode, M = 0.
, M = 1 in the schedule mode, M = 2 in the stopwatch mode, and M = in the timer mode.
When 3 is in the alarm mode, M = 4 is stored.

Next, the operation of the multifunction electronic timepiece having the above configuration will be described. FIG. 2 is a flowchart showing the overall operation of the multi-function electronic timepiece of the embodiment. Step S1 of FIG.
It is determined whether or not there is a switch input with. When there is a switch input, the switch process of the next step S2 is executed.

Here, the processing contents of the switch processing in step S2 will be described with reference to the flowchart of FIG. First, it is determined whether or not the mode switch S1 is operated in step S11 of FIG. If the operated switch is the mode changeover switch S1, step S
At 12, the value of the mode register M is incremented. Then, in the next step S13, it is determined whether or not the value of the mode register M is larger than "4".

If M> 4, it means that the mode changeover switch S1 has been operated in the alarm mode of M = 4. In this case, "0" is set in the mode register M in the next step S15. Switch to current time mode.

Next, in step S15, the mode register M
It is determined whether the value of is "2". If M = 2, it is further determined in step S16 whether the stopwatch counting circuit 9 is in the reset state.

At this time, if the stopwatch counting circuit 9 is in the reset state, "3" is set in the mode register M in the next step S17, and it is further determined in step S19 whether or not the subtraction timer circuit 10 is in the reset state. ..

If the subtraction timer circuit 10 is in the reset state, "4" is set in the mode register M in the next step S20 to switch to the alarm mode. If M ≠ 2 in the determination in step S15, the process proceeds to step S18, and it is determined whether or not the value of the mode register M is "3". M =
If it is 3, the process proceeds to step S19 described above to determine whether or not the subtraction timer circuit 10 is in the reset state. If it is in the reset state, "4" is set in the mode register M.

That is, when the switch S1 is operated in the M = 1 schedule mode, if the stopwatch measurement is not performed at that time, the stopwatch mode is skipped and the next timer mode is switched to. At this time, if the timer measurement is not performed, the timer mode is skipped and the mode is switched to the next alarm mode.

As a result, the mode in the reset state can be skipped and the next mode can be switched to, so that the desired mode can be quickly selected even when there are many modes.

If it is determined in step S11 that the switch S1 is not operated, the flow advances to step S21 to determine whether or not the switch S2 is operated. If the operated switch is the switch S2, the mode register M is processed in the next step S22.
It is determined whether the value of is "0".

When the switch S2 is operated in the current time mode of M = 0, "2" is set in the mode register M in the next step S23 to switch to the stopwatch mode. Then, in the next step S24, it is determined whether or not the stopwatch measurement is stopped. If it is stopped, the process proceeds to step S25 and the FF7 is set to start the stopwatch measurement.

If it is not stopped at this time, the process proceeds to step S26, the FF 7 is reset and the stopwatch measurement is stopped. Then, in step S27, it is determined whether or not the switch S2 is turned off, and the switch S2 is turned on.
If 1 is turned off, the process ends there.

If the switch S1 is not turned off in the determination in step S27, the process proceeds to step S28.
It is determined whether 1 has been pressed for 2 seconds or more. If the switch S1 is kept pressed for 2 seconds or more, it is further determined in step S29 whether or not the stopwatch measurement is stopped. If it is stopped, a reset signal is output in the next step S30 to output the stopwatch. The counting circuit 9 is reset. As a result, the contents of the stopwatch counting circuit 9 are cleared to "0", so that "0" is set in the mode register M in the next step S31 to switch to the current time mode.

At this time, if the stopwatch time is being measured, the FF 7 is reset in step S32 to stop the stopwatch measurement, and then the process proceeds to step S30.

That is, when the switch S2 is operated in the current time mode of M = 0, the switch is switched to the stopwatch mode of M = 2, and when the switch S2 is turned on for a short time, the stopwatch measurement starts or stops, and the stopwatch measurement is continuously performed for 2 seconds or more. When kept pressed, the measurement time of the stopwatch counting circuit 9 is cleared.

If M ≠ 0 in the determination in step S22, the switch S2 is set in a mode other than the current time mode.
Is operated, and in this case, step S33
The S2 process in another mode is executed.

On the other hand, if it is determined in step S21 that the switch S2 is not operated, the flow advances to step S34 to determine whether the switch S3 is operated. If the operated switch is the switch S3, it is determined in step S35 whether the value of the mode register M is "0".

When the switch S3 is operated in the current time mode of M = 0, "3" is set in the mode register M in the next step S36 to switch to the timer mode.
Then, in the next step S37, it is determined whether or not the timer measurement is stopped. If the timer measurement is stopped,
In step S38, the FF8 is set to start the timer measurement.

At this time, if the timer time is being measured,
In step S39, the FF8 is reset and the timer measurement is stopped. Then, in step S40, it is determined whether or not the switch S3 has been turned off. If the switch S3 has been turned off, the processing ends there.

On the other hand, if the switch S3 has not been turned off, the routine proceeds to step S41, where it is determined whether or not the switch S3 is continuously pressed for 2 seconds or more. When the switch S3 is continuously pressed for 2 seconds or more, it is further determined in step S42 whether or not the timer measurement is stopped,
If the timer measurement is stopped, a reset signal is output in step S43 to reset the subtraction timer circuit 10. As a result, the timer is reset, and in the next step S44, "0" is set in the mode register M to switch to the current time mode.

At this time, if the timer time is being measured,
After proceeding to step S45 to reset the FF8 to stop the timer measurement, the process proceeds to step S43. That is, when the switch S3 is operated in the current time mode of M = 0, the timer mode of M = 3 is set, and when the switch S3 is turned on for a short time, timer measurement starts or stops,
If the button is continuously pressed for 2 seconds or more, the timer time of the subtraction timer circuit 10 is reset.

If M ≠ 0 in the determination in step S35, the process proceeds to step S46 to execute the S3 process in another mode. On the other hand, if it is determined in step S34 that the switch S3 is not operated, the process advances to step S47 to determine whether the switch S4 is operated.

If the switch S4 is operated, it is determined in the next step S48 whether or not the value of the mode register M is "0". If M = 0, the process proceeds to step S49 and the subtraction timer circuit 10 is operated. 1 minute is added to the timer time TM of.

Further, in the next step S50, the flag FH is set.
Is set to "1". Here, the flag FH is a flag that is set when the timer time is preset in the current time mode, and when the flag FH is "1", the preset timer time is displayed for a certain time in the display process described later. ..

If M ≠ 0 in the determination in step S48, the switch S4 is selected in a mode other than the current time mode.
Is operated, and in this case, step S5
The S4 process in the other mode of No. 1 is executed. Of course, even in the timer mode of M = 3, one minute is added to the timer time TM each time the switch S4 is operated.

If it is determined in step S47 that the switch S4 is not operated, the switch S5 is operated. In this case, the process proceeds to step S52 and it is determined whether the mode register M is "0". To do.

In the current time mode of M = 0, the switch S45
If is operated, 1 minute is subtracted from the timer time TM of the subtraction timer circuit 10 in the next step S53. Further, in the next step S54, "1" is set to the flag FH.

If M ≠ 0 in the determination in step S52, the switch S5 is set in a mode other than the current time mode.
Is operated, and in this case, step S5
The S5 process in the other mode of No. 5 is executed.

Thus, in the current time mode,
An arbitrary timer time TM can be preset in the subtraction timer circuit 10 by operating the switches S4 and S5. When the switch processing is completed as described above, the process proceeds to step S3 in FIG. 2 to check whether the current time matches the alarm time or the schedule time, and if they match, an alarm sound or the like is issued. After that, the display processing of step S4 is executed to perform display according to the operation mode.

FIG. 4 is a more detailed flowchart of the display process of step S4. Step S61 of FIG.
Then, it is determined whether the value of the mode register M is "0". M
If the current time mode is = 0, it is determined in the next step S62 whether the flag FH is "0".

If FH = 0, the current time display processing of step S63 is executed and the current time data output from the time counting circuit 3 is displayed on the display unit 14. At this time, FH =
If it is 1, it is determined whether or not the timer time is displayed for a certain time or longer. If it has not been displayed for a certain period of time or more, the process proceeds to step S65, and the preset timer time is displayed on the display unit 1.
Display in 4.

If it is determined in step S64 that the timer time has been displayed for a certain time or more, step S6
After proceeding to step 6 and setting the flag FH to "0", proceeding to step S63, the current time data is displayed.

According to the above processing, when the switch S4 or S5 is operated in the current time mode to preset the timer time, the preset timer time is displayed for a fixed time at that time, and when the fixed time elapses, the original current time mode is restored. ..

If M ≠ 0 in the determination in step S61,
It is a display in a mode other than the current time mode of M = 0, and in this case, the process proceeds to step S67 and a display corresponding to the operation mode at that time is performed.

As described above, in the above-described embodiment, when the mode changeover switch S1 is operated to sequentially switch the modes, it is possible to skip the mode in the reset state and proceed to the next mode. Even if it exists, the desired mode can be selected with a few switch operations.

The present invention can be applied not only to a dedicated device for an electronic timepiece, but also to a calculator or an electronic notebook having a timepiece function incorporated therein.
