Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a telephone equipped with a recording/playback function.

(Prior art and its problems) An answering machine with a recording and playback function attached to a telephone set, which has the function of recording a message from a caller when an incoming call is received while the user is away, and playing back the recorded content at a desired time. is widely used. However, with conventional answering machines, there is a response tape that records the response message issued to the other party when a call is received, and a message recorder that records the message from the other party that comes in response to this response message. Since it is provided separately from the tape, two systems of recording and playback functions are required, making the device large and uneconomical. As a solution to this drawback, a configuration has already been proposed in which a recording tape having two recording tracks is used, one recording track is used for recording the response message, and the other recording track is used for recording the business message. has been done. However, even in this latter case, since a plurality of tracks are provided, the recording/playback function needs to have a complicated configuration suitable for the plurality of tracks.

Furthermore, since the recording tapes of conventional answering machines are used without any particular division within the recording area of a series of recording tapes, the importance of the recorded information is not particularly relevant when reproducing the message contents. The disadvantage is that unless you replay all of the information, you will not be able to understand the outline of the information. This is a particularly serious drawback when listening to the contents of a message by remote control from an outside line.

In addition, conventional answering machines are used only to record the message of the other party when receiving a call from an outside line, and if the answering machine has multiple owners, There are no plans to use this answering machine for communication between owners.

(Object of the Invention) In view of the above drawbacks of the prior art, the present invention records a response message and a message on a single recording track, and records a plurality of recording blocks to which the recording track is sequentially assigned. Use it by dividing it into
Furthermore, the recording block is integrally formed with the telephone so that it records voice input from the line as well as direct input from the microphone, and an audio message type that allows efficient playback of the recording block. It provides telephones.

(Structure and operation of the invention) The present invention will be explained in detail below with reference to the drawings.

First, the allocation format of the recording tape recording area used in the present invention will be explained. FIG. 1 shows an example of this recording area allocation, and one of the features is that the recording area is sequentially divided into a large number of blocks on the recording tape 1 as shown in the figure. Response area AM for recording response messages and message area G for recording message messages.
Another feature is that S is assigned to one recording tape. The response area AM is arranged at an intermediate position between the start end ST and the end ED of the recording tape, and consists of a response recorded message block AM _a and a response-only message block AM _b . The response-only message block AM _b is a recording block that records a response-only message (for example, "We are closed today,""I am out of the office," etc.) that does not involve recording the business, for example, for 60 seconds. A length of time has been assigned. Answer recording message block
AM _a is a recording block that records response recording messages accompanied by recording of business matters (for example, "I am not home at the moment. I will record your business, so please speak when the beep sounds. Please go ahead."). Yes, and for example, a time length of 60 seconds is assigned like AM _b . After the response area AM, there is a general business area G for each block G ₁ , G ₂ ..., G ₁₀ , for example.
They are arranged sequentially as shown in the diagram with a recording gap of ₆ seconds between blocks with a time length _{of 40 seconds} . Record the content of the call. One of the features of the present invention is that the recording blocks S ₁ , S ₂ , S ₃ , S ₄ of the specific business area S are provided outside the recording blocks G ₁ , G ₂ , ..., G ₁₀ of the general business area G. This feature is that the recording blocks _S1 ,... _S4 of this specific message area S store specific message messages instead of so-called "memos" for mutual communication between multiple parties using this telephone. Record. Recording in this case can be done by directly putting a message into the desired recording block S ₁ , S ₂ , S ₃ or S ₄ of the device using a microphone, or by remote control after connection from the subscriber line. Access can be made using a password or the like, and recording of a message can be performed in a predetermined recording block S ₁ , S ₂ , S ₃ or S ₄ . The time lengths of recording blocks S ₁ , S ₂ , S ₃ , S ₄ are, for example, general business recording blocks G ₁ , G ₂ ,...G ₁₀
40 seconds is selected, the same as the time length of .

The recording tape 1 is stopped so that the first waiting point _P1 , which corresponds to the beginning of the response recording message block AM _a in the normal response area AM, faces the head, and when a call is received, the response recording message block is stopped.
After reproducing and transmitting the message of AM _a , the receiver moves to the first blank block among the recording blocks G ₁ , G _{2 ,} . In a similar operation, when messages have been recorded in all recording blocks G ₁ , G ₂ , ..., G ₁₀ , the head is sent to the second waiting point P ₂ corresponding to the beginning of the response-only message block AM _b . Recording tape 1 so that
is stopped, and the system is controlled to play and send a response-only message in response to incoming calls. Recording blocks S ₁ ,...S ₄ in the specific message area S can be accessed when controlled by the control button or by remote control using a PIN number when receiving a call, and can be accessed to record specific message messages or Control is performed so that the recorded content can be played back.

By pressing one of the "General" buttons,
By specifying either the response area AM, specific area S, or general business area G, and pressing the desired one or two number buttons on the dial circuit 11, you can select any of the display addresses of each of the above-mentioned recording blocks. is selected. The display address information selected in this way is set in the block address register within the microcomputer 20. Therefore, when the display address information set here matches the display address displayed by the address means,
By controlling the plunger 6 and the forward/reverse speed control circuit 4 via the latch 27, it is possible to stop the recording tape 1 while cueing a predetermined recording block.

Due to the above configuration, specific operations can be performed as follows.

First, in the case of recording a response message, the display address of the response recording message block AM _a can be set immediately when the "Response" button of the function key 21 is pressed. As a result, the plunger 6 and the forward/reverse speed control circuit 4 operate via the latch 27 as described above.
The motors 5a and 5b are driven at high speed, and the magnetic head 2 is placed at the beginning of the response recording message block AM _a.
The drive stops when the magnetic tape 1 faces the magnetic tape 1.
The drive of will be temporarily stopped. Now, by pressing the "Record" button on the function key 21,
Switch elements AS ₁ , via latches 26 and 27
AS ₇ and AS ₁₂ are turned on, the recording/playback switch 54 is switched to the recording preamplifier 52 side, and the plunger 6 and forward/reverse speed control circuit 4 are operated to drive the motors 5a, 5b at normal low speed. Ru. Here, by issuing the guidance signal GD,
An 800 Hz signal can be heard from the speaker 49 from the oscillator 41 via the path of [inhibit gate 42 → amplifier 43 → switch element AS ₈ → volume VR → amplifier 48], and at this time, the microphone 51
By uttering a recorded response message toward the microphone 51 → switch element AS ₁ →
Recording preamplifier 52 → Recording playback switch 54
→ switch element AS ₇ → switch element AS ₁₂ → recording amplifier 55] is applied to the magnetic head 2,
A desired response message can be recorded. An example of a recorded response message is: [Yes, this is Kobayashi, but I am currently on a business trip and will be away until 〇〇. We apologize for the inconvenience, but please follow the female voice guidance and record your request. Thank you. ``Now, I would like to guide you through the recording process.The recording time is about 40 seconds.Please tell us your name, phone number, and what you want to do.Here you go.'' (Voice guidance). Here, the voice guidance is transmitted from the voice synthesizer 33 after the response recording message [filter 40 → amplifier 43 → line amplifier 45 → switch element AS ₅ → telephone circuit 1
0] to line 12.

By pressing the "Record" button again, it will enter the automatic playback mode of the recorded response message.
[Magnetic head 2 → switch element AS ₁₁ → playback preamplifier 53 → recording/playback selector switch 54 → switch element AS ₇ → switch element AS ₈ → volume VR→
The content can be confirmed by the reproduced sound via the speaker amplifier 48→speaker 49]. Also,
Since the voltage is applied from the line amplifier 45 to the audio switch 46, when the response recorded message is normally played back, the output 0 _{to 1} is sent to the microcomputer 2.
0 and then allows setting to away mode.

In addition, after playing the recorded response message, click "Play".
By pressing the button, the response-only message block AM _b is designated as described above, and by pressing the "record" button here, the response-only message can be recorded via the microphone 51 in the same manner as described above. An example of a response-only message is ``Yes, this is Kobayashi, but I am not available at the moment. We apologize for the inconvenience, but please try again later. ].

This response-only message is handled in the same way as the response recorded message, and is automatically played back. Only when the playback output is obtained as output 0 _{or 1} by the audio switch 46 can the transition to the away mode occur. It can be configured as follows.

Each recording block G ₁ , G ₂ , in general business area G
...G ₁₀ is accessed via the subscriber line 12.

In away mode, the recording tape is the first standby point.
While on P ₁ , there is an incoming call from subscriber line 12.
When the incoming call detection output IR is detected by the microcomputer 20 and the line is closed by the L relay, the switch elements AS ₁₁ , AS ₇ , and AS ₅ are turned on to send out the response recording message, and the recording is started. The playback selector switch 54 is switched to the playback preamplifier 53 side, and the plunger 6 and forward/reverse speed control circuit 4 are operated via the latch 27, so that the response recording message is changed to [magnetic head 2 → switch element AS ₁₁ → Playback preamplifier 53 → Recording/playback selector switch 54 → Switch element AS ₇ → Line amplifier 45 → Switch element AS ₅ → Telephone circuit 1

By selecting 4, the voice guidance will be sent to the voice synthesizer 3.
3 to the subscriber line 12 via the path [filter 40 → amplifier 43 → line amplifier 45 → switch element AS ₅ → telephone circuit 10].

After the recorded response message and voice guidance are sent out, the microcomputer 20 is moved so that the magnetic head 2 faces the head position of the magnetic block (for example, G ₁ ) in the nearest empty general business area G.
Servo 3 and motors 5a, 5 by addressing
The magnetic tape 1 is driven by the operation b. When the completion of this operation is detected by matching the display address of the recording block as described above, the guidance GD
is generated, and the guidance signal is [oscillator 41 → inhibit circuit 42 → amplifier 43 → line amplifier 4
5 → switch element AS ₅ → telephone circuit 10 → line 12], and when the transmission is finished, the recording/playback system is in recording mode, and magnetic tape 1 starts running at normal speed. . Therefore, at this time, if the person on the other end of the call speaks about the business,
The conditions are as follows: line 12 → telephone circuit 10 → switch element AS ₂ → recording preamplifier 52 → recording/playback selector switch 54 → switch element AS ₁₂ → recording amplifier 55. Recorded on G ₁ .

After this recording is finished, the microcomputer 2 confirms that there is recording in this recording block _G1 and that it is not empty.
It is registered in the recording block register in 0.

By pressing the "General" and "Play" buttons on the function key 21, the contents of the registered recording blocks are displayed in the recording tape driving means 27 in the order of recorded recording blocks recorded in the register in the microcomputer 20. ,6,4,5a,5b,

In the case of playback by remote control from the local line 12, the remote control signal is transmitted as follows: [local line 12 → telephone circuit 10 → switch element AS ₃ → amplifier 44 → PB
On the path from the signal receiver 23 to the microcomputer 20, the signal is transmitted to the microcomputer 20 and decoded, and in addition to the recording tape drive means, another reproduction circuit system 2, AS ₁₁ , 53, 54, AS ₇ , 45,
The content of the recorded block reproduced via AS ₅ and 10 is sent to subscriber line 12.

Also, during such playback operation, for example (1) if the content of the message is not important enough to need to be listened to now, or (2) during playback of the message contents, it is possible to read the outline or all of the message thoroughly. There may be cases where there is no need to listen to the recorded content, such as when the subject is understood or (3) the content of the matter has already been played back and listened to. At this time, a predetermined control signal is transmitted by the function key 21 of this device, or the predetermined control signal transmitted by remote control from the joining line 12 [for example, #0#]
The microcomputer 20 determines this, and the recording tape drive means temporarily stops driving the tape 1. Here, the microcomputer 20 determines whether a registered recording block exists or not by referring to the contents of the register, and if a registered recording block exists, the recording tape driving means moves the tape 1 in the forward direction or It is driven in the opposite direction at high speed and performs a so-called cueing operation using a normal playback operation at the starting end of the most recently registered recording block, and reproduces the contents of the recording block. In this way, it is possible to efficiently reproduce recorded matters in a short and efficient reproduction time.

FIG. 3 is a flowchart showing the operation of the apparatus of the present invention. Since the operation described above is simply summarized, detailed explanation will be omitted.

As described in detail above, according to the present invention, a plurality of recording blocks are sequentially allocated on the recording tape based on a count value obtained by counting the number of revolutions of the reel of the recording tape 1 from the start or end of the recording tape.

0, 27, 6, 5a, 5b, 3, and 4 can be realized.

(Effects of the Invention) As explained in detail above, since the present invention uses a single recording track, the recording/playback drive mechanism is simplified, and the recording track is divided into a large number of sequentially assigned recording blocks. Due to the partitioned nature, access control is easy and quick to perform. Therefore, by sequentially specifying unlistened recording blocks, it is possible to extract, reproduce, and listen to only the most urgent and important recording contents in an extremely short period of time. Furthermore, when a plurality of owners share the same, it is possible to easily and reliably communicate with each other.

Furthermore, by simplifying the configuration as described above, it becomes easy to adopt a structure in which the above-mentioned functions are integrated with a telephone set, which has an extremely large practical effect.
