Abstract

PURPOSE:To inform surely the end of a tape to a caller, by providing a means detecting the end of the tape recording a message from the caller and informing it to the caller. CONSTITUTION:When the end of an ICM comes and a message of the caller is recorded to an ICM tape section 314, a tape end detecting section 338 detects it. When this tape end detecting output is applied, a control circuit 312 applies a control signal to perform a prescribed operation at the end of the ICM tape to the voice synthesis section 315 with a clock function. Thus, the voice such as ''End of tape'' is transmitted to the caller from the voice synthesis section 315 via an analog switch S16, an amplifier 327 and a transformer 320.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to improvements in automatic telephone answering devices used as answering machines.

[Technical background of the invention]

2. Description of the Related Art Conventionally, an automatic telephone answering device configured as shown in FIG. 1, which is used as an answering machine, has been known.

That is, when a discharge signal (bell signal) arrives from the caller's telephone 11 via the exchange 12, the bell signal detection circuit 13 detects it and starts the timer operation, and turns the first relay 14 on. shall be. This closes the normally open contact 14 to form a telephone line connecting the telephone line A-A' to one side of the line transformer 15.

At the same time, the normally open contact 142 is closed, and the motor 16 is driven through the normally closed contact 20 of the second relay 20, which will be described later.

Then, the endless tape 17 that is run by the motor 16 is played back by the playback head 18.
The response message previously recorded on the endless tape 17 is transmitted to the telephone line via the regenerative amplifier 19 and the normally closed contact 2o3 of the second relay 20, and further through the line transformer 15.

Here, when the endless tape 17 makes one round, the conductive foil 17a stuck on the tape 17 short-circuits the pair of electrodes 2 and connects the second electrode via the normally open contact 143 which is previously opened. The relay 20 is turned on. This second relay 20 is brought into a self-hold state by closing its normally open contact 205.

At the same time, the small opening contact 202 is opened to stop the motor 16 and drive the motor 22. Then, the motor 22 starts running the recording tape 230, so that the message from the caller is transferred to the normally open contact 204 and the recording amplifier 2, which are in the closed state at this time.
4. Further, the recording can be completed via the recording head 25.

When the timer operation of the bell signal detection circuit 13 ends after a predetermined period of time has elapsed, the first relay 14 returns to the OFF state and the second relay 20 returns to the OFF state. After the operation is completed, the telephone line is returned to its original standby state.

In the above process, the caller is prompted by the response message from the endless tape 17 and the subsequent beep sound to utter a message.

[Problems with background technology]

However, with conventional automatic telephone answering devices such as those described above, the caller is prompted to say a message by a beep sound, etc. that is sent out after the response message, so it is difficult to decide when to speak. In addition, it has the problem that it tends to cause discomfort to the ears. Furthermore, since it is difficult to get the right timing to speak, the recording tape 23 tends to be run in vain, resulting in a serious drawback in that important messages cannot be recorded.

Furthermore, there is a problem in that it is difficult to take effective measures to notify the calling party that the recording tape 23 has ended.

There are still cases where the user uses a telephone line from outside to carry out remote control operations, such as reading out messages received by telephone while the user is away, and recording tapes are not available to record how long a call was made. There is the inconvenience of not being able to see all of the previously recorded parts of 23 in the trench, and furthermore, the last part cannot be known unless you listen to it for a while, which tends to cause a loss of time. had.

Furthermore, if you want to record time information when recording a message, you have to use a complicated configuration such as using external equipment, and you also have to provide the caller with information about the time before and after the day off. There has been a problem in that effective JM measures cannot be taken to notify information as necessary.

Furthermore, since no effective measures have been taken to detect when the caller hangs up the telephone, there is a problem in that the caller tends to continue the call in vain.

In addition, if the user is not out of the house but is simply within a relatively short distance from the telephone, if the user attempts to listen to a message from the caller or communicate with the caller without directly answering the telephone, However, there was also the inconvenience of having to give up the project because no measures had been taken to deal with it.

Furthermore, although the response message is pre-recorded on the endless tape 17, the endless tape 7''17
The problem has been that the product itself tends to have a relatively short lifespan due to repeated use.

There was also the problem that the BS did not have effective h(!i) measures against multiple calls coming in at the same time, including during a call.

However, since the endless tape 17 and the recording tape 23 are used, there is a problem in that the overall size and weight of the device and the low gravity consumption tend to be hindered.

Furthermore, when reading by remote control, there is a problem in that a dedicated remote control operation device with a complicated configuration is required in order to maintain confidentiality.

[Purpose of the invention]

Therefore, this invention was made in view of the above points, and is an extremely improved telephone that has been improved so as to be able to reliably notify the caller of the end of the tape recording the message from the caller. The purpose is to provide an automatic response device.

[Summary of the invention]

That is, the automatic telephone answering device according to the present invention receives a telephone call from a caller, sends a prerecorded response message to the caller, and is capable of recording a message from the caller. In the device, a first means for detecting the end of the tape for recording a message from the caller, and in response to the first means, sends a voice synthesis output for notifying the caller of the arrival of the end of the recording tape. The present invention is characterized in that it comprises a second means for.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 2 shows an external view of the implementation of an automatic telephone answering device to which the present invention is applied and which can be used as an answering machine.
(Outgoing message) Tape loading section 212
are arranged in parallel on the upper plane part of the cabinet 210.

On the lower slope of the cabinet 21o, there is a lock operation key 214 that can emit the current time from a speaker sound emitting section 213 each time the cabinet is operated, and a tail recorder mechanism (however, a tail recorder mechanism, such as a plantar etc. A lobby (also used for rewinding) operation key 21 for operating the camera to a predetermined state.

A reception set operation key 226 is provided, as well as a volume adjuster 227 and an answering machine display 228.

Here, the OGM operation key 222 is used to record a message to be received while you are away on an 00M tape (however, it is made in an endless format) via a built-in microphone 229, as will be described later, and the contents can be checked. can be performed using the reproduction operation key 216f.

In addition, the answering set operation key 2261d is used to set the automatic answering mode while you are away, and as described later, it is possible to answer the caller and automatically record the message on the ICM tape. becomes.

In this case, the 2-way operation key 223 is used by the user to answer the phone and record the mutual conversation, and during this call, the recording state is activated at intervals of approximately 15 seconds. It also has the function of emitting a signal (bee f) sound.

The ICM playback operation key 225 can be used to play the ICM while you are away etc.
This is for playing back the contents recorded on the tape from the beginning, and whether or not a call has been received while the user is away can be determined by whether the answering machine display 228 is turned on or off.

Further, the dictate operation key 224 is used to use the ICM tape as a normal cassette recorder, and operations for each state are performed using the operation keys 215 to 220.

Note that an earphone terminal 2 is provided on the side of the cabinet 210.
A recording time selection switch 231 is provided for selectively limiting the recordable time for one recording of the ICM data.

FIG. 3 shows an electric circuit diagram of an automatic telephone answering device that can be used as an answering machine to which the present invention is applied.
2 to 226, etc., this operation section 311
The logic control circuit 312 that receives various operation signals from the OGM0M chip 313 and the ICM
It is possible to control the tag unit 314, the voice synthesis unit with clock function 315, etc. to a predetermined state.

First, the structure and operation of each part will be described, taking as an example the case where the above-mentioned response set operation key 226 is operated by the operating unit 31 to use the device as an answering machine.

In this case, the logic control circuit 312 includes a microcomputer, etc., and in this state, each part is initially in a standby state for answering the answering machine. It is assumed that the OGM0M CH3-3 has previously recorded messages for reception according to a procedure that will be described later.

When a ring signal (bell signal) arrives from the telephone 316 of an external caller via the exchange 317 while in such a standby state, the ring signal detection circuit 318 receives the ring signal a predetermined number of times. and supplies a detection signal to the logic control circuit 312. Upon receiving this detection signal, the logic control circuit 312 supplies a relay 319 with a signal.

As a result, the normally open contact 319a closes and the telephone line A
-A' is connected to one side of the line transformer 320 to form a speech line.

Further, the logic control circuit 312 includes a plurality of analog switches Sl inserted at various locations.

- Various control signals for controlling S21 to a desired state are output at predetermined timings, and in this case, O
In order to regenerate and drive the GM0M chip 313, the OGM head slig granger 321 and the capstor/motor drive circuit 322 are turned on.

As a result, the cab stan motor CM is driven and the response message pre-recorded in the endless OGM tape is transmitted from the OGM head 323 → analog switch StO → preamplifier 324 → buffer amplifier 325 → analog switch 8+2 → filter 326 → amplifier 327
→The signal is sent to the telephone line via the line transformer 320.

Further, in this case, the response message is branched into two branches after the buffer amplifier 325 and is supplied to the analog switch S13 → filter 328 → detector 329, and the end portion of the response message is detected by the detector 329. That will happen.

Logic control circuit 3 to which this detection signal is supplied
Reference numeral 12 is configured to supply a control signal to the voice synthesis unit 315 with a clock function to cause it to perform a predetermined operation at the end of the reception message.

This is a female-voiced standard language memorized voice that prompts the caller to leave a message after the answering message has finished, such as "Please speak", instead of the conventional beep sound. I'm home at ○ time ○ depending on the composite output
This is an operation in which the signal is sent along with a speech synthesis output that provides current time information such as "It's a minute".

That is, the voice synthesis output from the voice synthesizer with clock function 315 for prompting the message as described above is routed from the analog switch S16 to the volume adjuster 331 to the buffer amplifier 325 through the same route as in the case of the response message described above. It will be sent to the telephone line.

FIG. 4 shows a specific example of the speech synthesis section in the speech synthesis section with clock function 315, which includes an address counter 401, an address decoder 402, and a ROM 40J.
, a dedicated mask ROM 400 for audio data consisting of a P/S conversion circuit 404, a timing circuit 405, and a synthesis LSI I/F circuit 406, a ROM I/F circuit 411,
A synthesis LS consisting of a speech synthesis circuit 412, a DA converter 413, a manual control circuit 414, a synthesis control circuit 415, a CPU I/F circuit 416, and a timing circuit 417
This is a case where a CMOS LSI for speech synthesis using the known PARCOR method in combination with I4JO is adopted. Note that although the clock function section is not shown, the speech synthesis section 315 with clock function can be easily realized by employing a known clock function LSI.

Figure 5 shows the response message and the voice synthesis output for prompting the following message. °'I'm home○
This shows the timing chart for "'Please talk to me.
At the timing when the logical product of No. 1 and the reel motor forward rotation output shown in (c) of the same figure was taken, the voice synthesized output of °''It's Q:00 minutes now' and 'Please speak' as shown in (d) of the same figure was successively output. However, in this case, the time information transmission selection switch 332a, which is omitted in FIG.
If it is turned off in advance, a control signal for prohibiting the sending of time information is given to the speech synthesizer with clock function 315 via the logic control circuit 312, and a "talking" to encourage weight loss is performed as shown in the figure (,). "Please" is now sent to the caller.

At this point, the ICM tape unit 314 has already been driven for recording, and the ICM tape section 314 has already been driven to record.
The 70 ranger drive output for the rad slider is supplied to the CM from the logic control circuit 312.
As a result, Noran Noya 333 for ICM head slig
, the reel motor drive circuit 334 is in the on state.

It detects the end of the Q1 response message and sends out a voice synthesis output to prompt the caller to leave a message.
At the same time, recording drive for the ICM tape unit 314 is started.

As a result, the reel motor RM is driven, and the ICM output of the above-mentioned voice synthesis output of "It's Q o'clock and minutes" and "Please speak" is branched into two branches after the buffer amplifier 325, and the analog switch S6 → ICM head 33.
5, and the message from the caller is subsequently recorded smoothly at a very natural timing without any delay. In this case, the message from the caller passes through the line transformer 320 → analog switch StS, preamplifier 324 → buffer amplifier 325, and then goes to the ICM tag unit 31 via the same route as the recording route of the voice synthesis output described above.
4 will be recorded.

Note that the time information may be recorded in the CM0M chip 314 not before the caller sends the caller 1, but at the end of the caller 1, and the form of such recording may be determined by changing the switch switching means as necessary. It is also possible to provide a single track or a plurality of tracks for recording. Furthermore, even if time information is not sent to the caller, it is assumed that the ICM0M team is configured to record time information simply by operating the switch 332a; Alternatively, another switch may be provided to enable selection as to whether or not to record time information in the ICM data.

Furthermore, by simply operating the switch 332a that prohibits the transmission of time information to the caller, the voice synthesis output for prompting the caller to send a message is masked so that it is not recorded by the ICM0M chip. However, if necessary, other switches may be provided so that a selection can be made as to whether or not to record the voice synthesis output for promoting communication on the ICM tape section 314.

Here, the time information is recorded in the ICM tape section 314 so that when the tape is played back later, it will be convenient to know what time the telephone message was received while the user was away. If the event is not just one day but spans many days, it becomes unclear what time it is on a typical day. Therefore, in order to be able to deal with such cases effectively, it is necessary to include day of the week information from Sunday to Saturday (English candy is also acceptable) or day of the week from Sunday to Saturday before the time information as described above. The speech synthesis unit 315 with a clock function may be configured so that the speech synthesis output can be obtained by adding information on the number of days elapsed, such as the date and time.

It should be noted that the day of the week 1st grade lφ or the number of elapsed days information may be output and displayed, and the output form of each of these pieces of information may be an appropriate abbreviation other than those described above. In addition, it may also be notified by the number of so-called beef rounds.

As described above, when the end of the ICM tape arrives while recording the caller's first message to the ICM tape section 314, the tape end detection section 338 detects it. The logic control circuit 312 to which the tape end detection output is supplied has a clock function and a beat sound synthesis section 330.
A control signal for performing a predetermined operation at the end of the ICIVi tape is supplied to the ICIVi tape.

In other words, this is an operation in which when the end of the ICM tape arrives, a voice synthesis output such as ``Tete has ended'' is sent out in order to make the caller aware of it, and the necessary sending path for this is described above. This is similar to the route taken by a speech synthesis output such as a message to the caller, ``Please speak to me, please.''

Figure 6 shows a timing chart when transmitting tape end information such as 'Patezo has ended' as described above.
b) shows the generation state of the tape end detection signal, (c) shows the generation state of the control signal, and (d) shows the generation state of the tape end detection signal.
``The tape ended'' at the timing when I took the logical product.
This shows the generation state of the speech synthesis output.

If the tape recorder mechanism is equipped with an auto-reverse function, the message ``Please wait for a while'' will be sent after ``The tape has finished playing'', and the message ``Please wait for a while'' will be sent after the auto-reverse is completed. It may be possible to send out a speech synthesis output such as "Sorry to have kept you waiting, please talk to me."

Incidentally, in order to record a reception message for the OGM tape section 313 in the above, it is sufficient to operate the OGM operation key 221 of the operation section 311 and input the desired reception message into the built-in microphone 229. One! C,
This allows the logic control circuit 312 to
Various control signals are supplied to the M tape section 913 for recording a reception message. That is, the built-in microphone 22
A recording path is formed as follows: 9→analog switch 811→preamplifier 324→buffer amplifier 325→analog switch S9→ODM to RAD 323.

Furthermore, in order to play back the message of the missed call recorded in the ICM0M team 314, the ICM playback operation key 225 of the operation unit 311 may be operated. This allows the logic control circuit 312 to supply various control signals for putting the ICM0M chip 314 into a reproduction driving state. That is, ICM
Head 335 → Analog switch S7 → Preamplifier 32
4 → Volume adjuster 331 → Output amplifier 336 → Speaker 3
37 regeneration paths will be formed.

It should be noted that the power supply voltage for driving is supplied to the output amplifier 336 only in the reproduction state, so that no sound is emitted from the speaker 337 when it is used as the above-mentioned answering machine. do.

And OGM0M Chi 313 or ICM0M Chi 3
14, a predetermined erasing signal is supplied from the logic control circuit 312 to the erasing head 361 or 362 via the analog switch S@ or S11.

In addition, in order to play back the weight of calls recorded on the CM6M Qi 314, such as when you are away, you can do so remotely without operating the ICM playback operation key 225 on the operation unit 311 and without using a telephone line. What can be done is possible.

This remote control playback operation is effective when you are in a relatively short distance, such as in another room, without being away from home.In this case, you can use the remote control playback mode directly using sound (waves). It is characterized by the fact that it can be used as

In other words, as shown in FIG. 3, a remote controller similar to the remote control device used to perform remote control playback operations using a telephone line with respect to the remote control microphone 340 provided in the main body of the device is used. Using the control device 341, the speaker 341a may generate a ring tone (wave) coded to have a predetermined confidentiality.

The output from the microphone 340 that picks up this calling sound (wave) is transmitted to the amplifier 3 which has band characteristics equivalent to that of a telephone line.
42→analog switch 814→filter 328→detector 329 (in this case, it is assumed that it functions as a tone decoder). Detected.

Logic control circuit 3 to which this detection signal is supplied
12 rewinds the ICM0M tape 14 and puts it into the playback driving state (
This system is designed to supply various control signals for skipping (possible skipping if necessary), and a reproduction path similar to that described above will be formed hereafter.

With this, the user can hear the message recorded on the ICM tape by the sound emitted from the speaker 337 without being near the device itself.

By the way, regarding the remote control operator 34, in this case, the ring tone is not directly input to the telephone as in the case of using a telephone line, but the ring tone is input to the microphone 340 from a certain distance. (waves), so compared to the former, it is necessary to output a relatively large output according to the distance. Therefore, in consideration of this point, in order to ensure that the ring tone output can be output reliably without causing erroneous operation when used in any condition, an output variable adjuster is installed in addition to the set of predetermined operation mode specifying keys. 341b, the remote control operating device 34 is provided with a remote controller 341b.

In this case, the remote control operator 341 generates an equivalent ring tone (wave) from its light emitting element 341c instead of generating a ring tone (wave) coded to have a predetermined privacy from its speaker 341a as described above. It is designed such that the calling light (wave) can be output by switching the switch 341d. That is,
This is to be used depending on which call output is more advantageous to use depending on the distance at that time and the situation of the harmful object on the way.

When the call light (wave) from the light emitting element 341c is used to enter the remote control playback operation mode without using a telephone line, the call light (wave) is collected by the above-mentioned ring sound (wave) on the device main body side. After being photoelectrically converted by a light-receiving element 346 such as a phototransistor, which is provided approximately in parallel with the sound microphone 340, the signal is guided to the above-mentioned amplifier 342 and thereafter, and is processed in the same manner as the ringing sound (wave). It will be used to obtain the reproduction state of.

Next, a case will be described in which the remote control playback operation mode is set using a telephone line.

That is, in this case, as shown in FIG.
By selectively operating the operation keys 342 and 343 attached to the , you can not only rewind and drive the ICM0M tape 14 in response to a remote control playback call from the telephone line, but also control the playback output. It is designed to be able to send out a voice synthesis output that informs the user of the number of phone calls that were made while the user was away, and that the message to be played back has ended.

First, to explain the case where the operation key 342 is operated, the user needs to use the aforementioned remote control operation device 341 or the like to transmit a signal to set the remote control playback operation mode from an external telephone. be. This remote control signal is transmitted via the telephone line in the same way as the voice signal through the line transformer 320 → preamplifier 324 → buffer amplifier 325 → analog switch 813 → filter 328 → detector 329.
(However, in this case, it functions as a tone decoder or a remote control signal decoder). is detected.

Logic control circuit 3 to which this detection signal is supplied
12 puts the ICM tag section 314 into the reproduction driving state in the same manner as described above, and outputs the reproduction output from the ICMC ahead 5 → analog switch S7 → preamplifier 324 → buffer amplifier 325 → analog switch 812 → filter 326 → amplifier 327. →It is designed to be able to supply various control signals to be sent to the telephone line via a line transformer 320, but in this case, the first remote control circuit 34 is also connected.
4 is in the driving state, and as soon as the reproduction output of the ICM0M Q 314 is finished, the voice synthesis unit 315 with a clock function immediately outputs a voice synthesis output saying "Message playback has ended" to the telephone line through the same route as those described above. The control signal is designed to be able to be sent to the user.

That is, in this case, the first remote control circuit 34
4, the number of detections by the bell signal detection circuit 318 is counted (N-1) in advance via the analog switch 818.

After that, when there is a call from the user using the telephone line to set the remote control playback operation mode, the playback output from the buffer amplifier 325 is read through the analog switch S19 and the number of intervals between each message is calculated. Make it count. Then, in the process of comparing these two count values, when the two count values match, the first remote control circuit 3'44 causes the voice synthesis unit with clock function 315 to reproduce the message as described above. It is designed to supply a control signal for producing a predetermined speech synthesis output for recognition of termination.

Here, the number of detections (N) of the bell signal detection circuit 318 is (
The reason why it is counted as N-1) is that one of the calls is for a remote control playback operation by the user.

Also, to explain the case where the operation key 343 is operated, the remote control playback operation mode itself is the same as the above case, but in this case, when there is a call that should be a remote control playback operation, the IC
Prior to driving the M0M Chi 314 to play, information about how many voicemails have been received up to that point is sent to the telephone line from the voice synthesizer with clock function 330 as a voice synthesizer output such as, for example, "3 calls have been received by sb." It is designed so that it can be sent to anyone.

Tsumushi, in this case the second remote control circuit 34
5, the number of detections by the bell signal detection circuit 318 (to) is counted in advance as (N-1) via the analog switch StO for the same reason as mentioned above, and then the user uses the telephone line to When there is a call to set the remote control playback operation mode, the count value is supplied to the audio synthesis section with clock function 315 via the analog switch 821. Further, the voice synthesis unit 315 with a clock function is configured to be able to selectively utter predetermined voice data from voice data that has been synthesized and analyzed in advance in accordance with the input of the count value.

Note that if the operation keys 342 and 343 are operated together, the above two functions can be performed in combination, and
First and second remote control circuits 344, 3
It goes without saying that 45 can be easily realized by appropriately combining known counter circuits, latte circuits, unrecorded portion detection circuits, comparison circuits, subtraction circuits, and the like.

When setting the remote control playback operation mode using the telephone port m, the power supply voltage to the output amplifier 336 is cut off so that the power supply voltage is not supplied to the output amplifier 336.
It is assumed that consideration is given so that no playback sound is emitted from 37.

Next, a remote response mode added to the above answering machine function will be explained.

In other words, this is similar to the case of using the remote control playback operation mode without using the telephone line mentioned above.
This is suitable when the user is not at home and is in a relatively close distance, such as in another room, so that the device itself functions as an answering machine and allows the user to answer calls from outside at a remote location. This is what I did.

Specifically, as shown in FIG. 3, all you have to do is operate the operation keys 347 attached to the operation section 31, and when you receive a call from the caller, In the same way as above, a series of answering machine functions such as sending out a response message, sending out a voice synthesis output prompting the caller to leave a message, and recording the message from the caller are performed, and at the same time, the logic control circuit A control signal for driving the receiving section 348 and the transmitting section 349 is supplied from the receiving section 312.

As a result, the preamplifier 3 in the path for recording the message from the caller (this can also be the transmission path for the answering message)
24 output is sent to the receiving section 34 via the analog switch S17.
After being supplied to the antenna 35 via the transmitter 349
0 is transmitted in the air, for example, as a citizen's band (CB) signal.

After this transmitted wave is guided to the receiving section 351b via the antenna 351a of the transmitter/receiver 35, such as a handy transceiver, which is in the hands of a user located at a remote location,
The user listens to it through earphones or speakers 351C. Furthermore, if the user receives such a message and inputs a response thereto into the microphone 351d of the transmitter/receiver 35, the response is sent to the antenna 35 via the transmitter 351e.
After being sent out during y by 1a, it is guided to the receiving section 348 via the antenna 350 on the automatic telephone answering device side, and then the analog switch 5174 buffer amplifier 325 → analog switch S-R filter 326 → amplifier 327 → line transformer 320 The data will be sent to the telephone line via the following route.

In this case, if the user turns on the switch 351f on the side of the transmitter/receiver 35, the message from the caller received by the receiver 351b will be transferred to the tape recorder 351g.
Since the caller's message is recorded, it is convenient to be able to immediately play back the caller's message as needed without having to go to the automatic telephone answering device.

In this case, if the switch 351h is turned on at the same time, the user can record the user's response from the transmitting section 351e to the tape recorder section 351g, which is a so-called two-way system. This will make later playback more convenient.

Note that the tape recorder section 351g is preferably integrated with the non-transceiver transceiver, and it is particularly preferable that the tape recorder section 351g be of a microcassette type, since dubbing can be easily performed.

FIG. 7 shows a case where an 00M card section 313a is used in place of the endless OGM tape section 313 shown in FIG. The need for a tape recorder mechanism can be replaced by a single tape recorder mechanism for the ICM tape 314, which has the advantage of simplifying the configuration. Furthermore, if such a 00M card is used, there is an advantage that it can be done at a lower cost than an endless OGM tape when a plurality of 00M cards for each purpose are prepared in advance.

That is, in this case, a 00M card 371 in the form of a magnetic card such as a cash card is used, and when the 00M card 371 loaded in the card loading section 372 receives a call from outside, the aforementioned capstan is inserted. When the motor CM is driven, the loans 373 to 376 that are driven at the same timing are moved to run on the head section 323, and the pre-recorded reception message is played back. It is designed so that it can be returned to its original position.

Note that it goes without saying that the 00M card is not limited to a magnetic card, but can also be used as a card using other methods, and that other recording methods such as a barcode method may be appropriately adopted as the recording method.

FIG. 8 shows the OGM tape section 313 and I shown in FIG.
In place of the CMC-tape 14, an OGM recorder section 313b and an ICM recorder section 314a each made of a so-called solid-state recorder may be used, and according to this, no American tape recorder mechanism is required as an automatic telephone answering device. It has the advantage that it can only be realized with solid-state circuits using electronic technology. In addition to simplifying the configuration, the lid is smaller and lighter, has lower power consumption, and is easier to operate.

In this case, the OGM recorder section 313b and the ICM recorder section 3148 each use a solid state recorder, but as shown in FIG. is digitized by the A-D converter 910 and then stored in the built-in memory 911. At the same time, the digital data stored in the built-in memory 91 is sequentially read out and converted back to an analog signal by the D-A converter 912. The reproduced signal is output after removing sampling noise using a filter 913, etc., and the reproduced signal is outputted from the speaker via the preamplifier, output amplifier, etc. I will do it.

In this way, O
GM recorder section 313b and ICM recorder section 314
Since "a" can be replaced isometrically with the speech synthesis technique, it may be integrated with the speech synthesis section with clock function 315 shown in FIG. 3.

FIG. 10 shows the detector 329 shown in FIG.
By providing the audio Mk section 329a, the above-mentioned ``remote control playback operation mode that uses a telephone line'' can be set to the audio Mk section 329a in advance using the same telephone line as the telephone line without using a dedicated remote control playback operation device 341 or the like. This is a case where, for example, when the voice of a user (or more than one user) registered in the band is received from a telephone replay, ``message playback'' is recognized and a remote control playback operation mode can be realized.

It goes without saying that the present invention is not limited to the embodiments described above and illustrated, and that various modifications and applications can be made without departing from the gist of the invention.

〔Effect of the invention〕

Therefore, as described in detail above, according to the present invention, there is provided an extremely good automatic telephone answering device which has been improved so as to be able to reliably notify the caller of the end of the tape recording the message from the caller. It becomes possible to provide
