Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic telephone answering and recording device having a remote control device, in which secrecy can be maintained by setting various control signals by appropriately combining numbers 0 to 9 on a touchtone phone. It is an object of the present invention to provide an automatic telephone answering and recording device that can be used efficiently and reliably control various types of operation modes using various types of control signals.

Automatic telephone answering and recording devices currently in common use automatically answer incoming calls, inform the other party that you are away, and
It also has the function of recording the other party's business, but in order to listen to the contents of the recorded business, the device must be manually operated and played back after returning home.

It would be very convenient if the above-mentioned operation of listening to the recorded business contents could be performed by remote control from outside the home, and various methods have been proposed in the past. For example, Tokuko Sho 4
0-10323, J Tokuko Showa 40-10325, Tokuko Tokuko Showa 4
0-23129 and Japanese Patent Publication Publication No. 40-23130, etc., automatic telephone answering is carried out by blowing a special whistle into the handset or using a portable oscillator to send a certain signal in a remote location. The recording device uses a reed selector or filter that operates only at a certain frequency to receive the signal, automatically performs the necessary operations, and then sends back the recorded content. However, when a large number of devices of the same type begin to be used, the types of signals are limited to a small number, which is insufficient in terms of confidentiality.

On the other hand, there are also systems that use special combinations of signals to maintain confidentiality, such as Japanese Patent Publication No. 40-24284, Japanese Patent Publication No. 40-24284,
24682, Japanese Patent Publication No. 41-8641, etc., but the operation is very troublesome and there are still many problems before it can be widely put into practical use. In addition, all of the above methods require a whistle or a portable oscillator, and each device receives one or two types of signals, so it is not only possible to simply listen to the recorded content, but also to listen to the response tape. It has the disadvantage that it is difficult to provide a wide variety of functions, such as changing or correcting the contents of one's own message or preventing the deletion of recorded contents of important messages from the other party.

In addition, for example, after calling a rotary telephone equipped with an optional additional device (i.e., the receiving side) using the normal dialing method to make a call, the additional device can be called using the impulse generated by further turning the dial. remotely control the
A remote control device that cannot be operated with a number of impulses other than a predetermined number has been proposed in Japanese Patent Publication No. 38-12465, but it cannot be applied to the bush phone mentioned below.

In order to eliminate the above-mentioned conventional drawbacks, the present invention has developed a bush phone (bush phone system is called a touch tone system in the United States). M) It is used as a controller and uses each bare tone corresponding to the numbers 0 to 9 as a control signal, and when using a dial type telephone, it is different from this telephone that oscillates the same bare tone as a bush phone. This device enables remote control using the output of a portable oscillator in the body, and will be described in detail below with reference to the drawings.

FIGS. 1A, B, and C are external views of an automatic telephone answering and recording device, a bush phone, and a portable oscillator according to the present invention, and FIG. 2 is an external view of a selector section for adjusting received control signals.

In FIG. 1, 13 is a bush phone used as a controller, and 14 is also a portable oscillator. When controlling the device remotely, the owner of the device is the first, second, third, and so on. Send control signals for digits. When using a bush phone, the above three digit numbers are 0 to 1 of the bush button 13a.
Selected from 9 numbers. The portable oscillator 14 is also provided with buttons 16 for transmitting signals of each digit. As shown in FIG. 2, selectors 17 to 19 are provided on the bottom of the automatic telephone answering and recording device, which are used to set the numbers in each digit. 19 is used to set the second digit, and 19 is used to set the third digit. These three-digit control signals can be adjusted so that the owner can select any combination of them as a protection against transmission to callers who are not authorized to use the device. When the device receives the three-digit number, it performs the following control. First, when the device is in a message recording state and receives a preset three-digit number, the device enters a rewinding state and rewinds the message recording tape until a stop signal is detected.

After rewinding once, it is determined that a different function is controlled in accordance with each of the three digit numbers.
In other words, the first digit indicates the function to put the device into recording mode, and the second digit indicates the function to put the device into playback mode.
The third digit each has a function to put the device in the rewind state. Therefore, when the device is in the recording state, if it receives the signal of the first digit, it continues the recording state, and when it receives the signal of the second digit, it enters the playback state,
When the signal of the third digit number is received, the rewinding state is maintained only while the signal is being received, and when the third digit signal disappears, the rewinding state is automatically entered. Also, when the device is in the playback mode, when it receives the signal of the first digit, it goes into the recording mode, and when it subsequently receives the signal of the second digit, the mechanism of the responding device goes into the recording mode. It becomes possible to rewind the response message, and when the signal of the third digit is received, the rewind mode will be activated as long as the signal is being received, just like in the recording mode, and when the signal is no longer available, the rewind mode will rewind automatically. is in play mode. Furthermore, when the device is in the rewind state, it remains in that state only while the third digit signal is being sent, and when the signal disappears, it automatically enters the playback state, so controls are irrelevant except for the first call. There is. In addition, when listening to the recorded content of a business in a remote location, if the recorded content is important and there is a request to keep it in the recorded state, the next step is to prevent accidental deletion. You can record a stop signal anywhere you want to avoid rewinding to a certain point when a call arrives.

j That is, when the device is in the recording state, the recording of the stop signal is performed by further sending a signal of the first digit number for a certain period of time, for example, w seconds. In FIG. 1A, the response side cassette holder 1 of the device is loaded with an enondress tape cassette 2 in which a sending message has been recorded, and the message recording side cassette holder 3 is loaded with a general unrecorded cassette 4. . Record button 5 and play button 6
When the user presses , and then presses the stop signal recording button 7, a stop signal is recorded at the beginning of the business recording tape. After the recording of the stop signal is completed, when the standby button 8 is further pressed, the apparatus enters a standby state, and a standby lamp 9 lights up to indicate that the apparatus is in the standby state. When an incoming call is received in this standby state, the device enters an automatic response state, closes the direct current circuit of the central office line, and automatically starts sending an absence notice to the central office line.

At the same time, the operating lamp 10 lights up to indicate that automatic answering is in progress, and at the same time, the incoming call lamp 11 lights up to indicate that an incoming call was received while the user was away. When the response tape finishes sending out the notification of absence, a beep tone is sent to the caller to signal the start of recording the message. This beep tone is controlled and sent out by the sensing foil 12 attached to the endless tape in the cassette 2. In this way, the message recording tape operates and starts recording the caller's message. When one response and recording of the message is completed, the device automatically stops and recovers, and enters the state of waiting for the next incoming call. If a power outage or other power failure occurs while the device is automatically responding, all functions of the device will stop. In the case of a power outage, etc., when the power is restored, the response tape is cued to its beginning without the line's DC circuit being closed, and the device automatically enters the standby state.As described above, the device of the present invention It has a so-called answering machine function similar to a conventional automatic telephone answering machine.

Next, the remote control function of the device of the present invention will be explained.

When the current business recording tape has been completely recorded and the next recording is no longer possible, or when the end of the tape is reached (in the unlikely event that the tape is still playing or recording due to a malfunction during remote control as described below), release from the central office line. Instead, the device sends a signal indicating that it has reached the end of the tape, stops driving the tape, and goes into standby mode after the call ends. When the next call arrives, the device takes over, but no message is sent. Therefore, the owner (caller) of the device can remotely control the device by sending a control signal after hearing the beep tone.
If you want to remotely control the device and listen to the contents of a call that came in while you were away, you can call the phone connected to the device at home or work from outside the home, set it to automatic answering mode, and set the device to record the message. When the device is out of office, that is, when it hears the beep tone after sending out the notification of absence, it sends the signal of the predetermined three-digit number. As mentioned above, the signal is sent by pressing a button on the phone (if the calling party's phone is a bush phone). In the case of a dial phone, a portable oscillator is used to send signals from the transmitter. A fixed length interval for sending signals is determined in advance. For example, the length of the signal is 0. ?
As mentioned above, there are methods such as setting the signal interval to within 5 seconds. If these predetermined conditions are not met, the previously sent signal is invalidated, and control cannot be performed unless the signal is sent again. When a 3-digit number signal is sent in this way, the device compares it with a preset 3-digit number, and if they all match, the device immediately enters the rewind state and performs the task. Begin rewinding the recording tape. This tape rewinding continues until a stop signal on the tape is detected, but if it is desired to stop the tape rewinding, it is sufficient to send only the second digit signal at that point. In addition, due to fθ, the device changes from the rewinding state to the reproducing state. To perform rewinding again, only the signal for the third digit needs to be transmitted. However, in this case, as described above, the rewinding state occurs only while the third digit signal is being transmitted, and the rewinding stops when the transmission tone is stopped. When the device is in the rewinding state, when a stop signal is detected, the device changes from the rewinding state to the playback state and begins to send the recorded message to the caller. At this time, if you listen to the recorded content without sending the next control signal, the first digit of the three-digit control signal that was originally sent will appear on the tape at the end of the content. has been recorded, and from that point on the device enters the recording state from the playback state.
Therefore, the device continues to be in a silent state, but when the handset is hung up, it automatically stops due to the VAC operation and enters a standby state to receive the next call. On the other hand, if you hang up the handset while sending the recorded message, the device will remain in the same position)
The playback state continues, and as in the case described above, the device enters the recording state under the control of the first digit signal recorded on the tape, and then enters the standby state by the AC operation and receives the next call.

In addition, if you want to keep the recorded contents of the business you are currently listening to so that they will not be erased by mistake, use the first digit signal when the device is in either playback or recording mode. When the control signal is sent for a certain period of time, for example 11 seconds or longer, and the control signal is recorded, the device automatically stops recording and enters a standby state.

This recorded signal becomes a stop signal, and the next time the device is called up and remotely controlled, the device rewinds to the part where the stop signal was recorded and then immediately changes to the playback state. Therefore, the contents of the tape recorded before the newly recorded stop signal are not erased. Also, if you want to erase all the recorded contents of the message you just listened to and pause, continue to send the signal of the third digit and rewind the tape to the beginning of the tape. Then, the device changes from the rewinding state to the playback state, so after checking the stop signal recorded at the beginning of the tape, send the signal of the first digit number to change the device from the playback state to the recording state. Hang up the handset. The device then goes into standby mode, and the next time a call arrives, you can use the recording tape again from the beginning. Furthermore, if you are listening to a recording of a message during playback and want to listen to it again midway through, you can rewind the desired amount by sending the signal of the third digit for the amount of time you want to rewind. is possible.

After rewinding, the device immediately goes into play mode and you can listen to the content again. Also, if you want to add a comment to the recorded content while listening to the recorded content in the playback mode, send the first digit signal, enter the recording mode, send the necessary comment, and then record the message. can do.

Thereafter, the signal of the second digit number is sent, and the playback mode is activated so that the recorded contents of the message can be continuously listened to. Furthermore, if your plans such as going out change and you want to change the notification contents and the absence of the sender, do the following.

When the device is in the playback state, when the second digit signal is sent, the device on the recording side stops operating, and the device on the responding side starts operating. Then, when the operation of the apparatus is switched from the recording side to the responding side 7 by sending a signal to start recording the absence notice, the responding side enters the recording state and starts recording the contents of the new absence notice. After the tape has gone around once for recording, an automatic check of the recording is performed to confirm the contents of the new absence notice that was just recorded. Switching between these modes is performed by sensing operation. When the check is completed, the device automatically switches to the recording side and enters the playback state. Therefore, if correction is required again after checking, the above operation can be repeated. As described above, by sending control signals predetermined by the owner of the device, the owner of the device can remotely listen to the contents of calls received while the user is away, change the message sent, or change the message. It becomes possible to remotely control various operations such as erasing recorded contents, recording, and preventing deletion of important recorded contents.

As shown in Figure 1C, the portable oscillators used to control the device include an oscillator that generates the same signal as a bush phone, a speaker 15 that generates an oscillating sound, and a 3-digit number that each independently transmits a signal. button 16, a selector (not shown) that can arbitrarily select and adjust a three-digit number, and a power source battery (not shown).

Next, the operation of the constituent circuits shown in FIGS. 3 and 4 will be explained.

If you turn on the power switch S1 now, the power lamp P will turn on.
L1 is turned on, AC voltage is converted to DC voltage by power supply circuit X15, and DC voltage of, for example, 12 V is supplied to each circuit of the device through line 30.

The endless cassette 2 on which the sent message has been recorded is loaded into the response side holder 1 of the device, and the message recording cassette 4 is loaded into the message recording side cassette holder 3.

Then, when you press the recording and playback buttons 5 and 6, the recording selector switches S2-1 to S2-9 and the playback switch S4-1,
S4-2 is switched respectively. Subsequently, when the stop signal recording button 7 is pressed, the switches S7-1 and S7-2 operate, and the stop signal recording circuit X16 operates. Therefore, for a certain period of time determined by the circuit 16, the oscillation output of the stop signal oscillation circuit Xl4 is transmitted to the relay contacts Fl, e.
The data is supplied to the message recording head H3 via the recording head H3. On the other hand, the output of the stop signal recording circuit Xl6 is applied to the relay 22 through the line 31 to operate it.

Therefore, the motor M1 plunger P2 operates, and at the same time the recording amplifier Xl. At the same time, power is supplied to the recording amplifier Xl2, the bias oscillator Xl3, etc., and the message recording side device operates to record a stop signal on the message recording tape. After finishing recording the stop signal, press the standby button 8, and the absence recording selection switch S3-1. ~S3-5 switches, and relay control holding circuit X for relay 20 passes through switch S3-2.
Since the DC voltage is supplied to the circuit X4, the circuit X4 operates. For this reason, the response tape is driven, and when the endless tape goes around once and the sensing foil 12 comes to the sensor position, the sensor operating circuit X5 is activated to automatically stop and locate the beginning of the response tape. On the other hand, by switching the switch S3-2, the power supply voltage is supplied to the standby lamp PL2 through the switches S3-2, S4-2, and S2-9, and the standby lamp PL2 lights up to indicate that the standby state has been entered. In this state, when an incoming call is received at connection terminals Ll and L2 connected to the office line, the incoming signal flows from terminal L to the closed circuit of switch S3-5, relay contact d1, incoming signal receiving circuit X1, capacitor CA5, and terminal L1.
The receiving circuit X1 operates.

An incoming signal receiving circuit X2 operates in conjunction with this circuit X1, and the output of the circuit X2 is supplied to an incoming lamp holding circuit X3 and a relay 20 through a line 32. Therefore, the incoming call lamp PL3 lights up.

Further, when the relay 20 operates, the contact A2 closes, and the relay control holding circuit X4 operates, so that the relay 20 is self-held. Further, due to the operation of the relay 20, voltage is supplied to the response-side device driving planon gear P1, the motor (2), and the regenerative amplifier X9 via the switch S3-2 and the contact a1, and the response-side operation is started. At the same time, the output of the incoming signal receiving circuit X2 is supplied through the line 33 to the control holding circuit
is closed and the equipment is connected to the central line.

Further, the operation lamp PL4 is also lit to indicate that it is in operation. The output of the regenerative amplifier X9 then passes through a switch S2-5 and an attenuator consisting of resistors R6, R7, and R8 via a line 34, passes through contacts Bl and b2, and then is transferred to a transformer T2, a contact Jdl, a switch S3-5, and a terminal. The contents of the absence notification are sent to the central office line through the terminal. When the absence notification tape goes around once and the sensing foil comes to the sensor position, the sensor operating circuit X5 operates, and its output is supplied to the relay holding circuit X4 through the line 35.

Therefore, the hold on the relay 20 is released and the response side stops operating. At the same time, the output of sensor operation circuit X5 is on line 35.
The signal is supplied to the control holding circuit X7 through the control holding circuit X7, thereby holding the relays 21 and 22 and operating the recording side device. At the same time, the audio signal from the caller is sent to the terminal! , switch S3-5, contact d1, transformer T2, contact E2, contact b1, resistor Rl
l, Rl. It enters the recording amplifier Xl2 via the attenuator and contact ■. The output of recording amplifier Xl2 is connected to contact F from line 36.
2. The signal is supplied to the recording head H3 on the message recording side via the contact e1, and the message contents are recorded. Of course, at the same time, the bias oscillation circuit Xl3 operates upon being supplied with voltage, and supplies bias current to the heads. Further, when the transmission of the absence notification contents is completed and the mode is switched to the recording side, the sensor operation circuit X5 is operated, and its output is supplied to the beep tone oscillation circuit X6 through the line 37 to operate it.

The output of circuit X6 is sent via line 38 through transformer T2, contact switch S3-5, and terminal to the caller, informing the caller that the apparatus is to be switched to the message recording state. In the above operating sequence, the device enters the message recording state and records the message from the caller.

At this time, the recording contents are monitored by monitor switches S5-1 and S5-
By switching 2, the sound can be heard through the speaker 26. While there is voice input from the caller, the output of the recording amplifier Xl2 enters the VAC circuit XlO from the line 39, so the output of the circuit XlO is supplied to the control holding circuit X7 through the line 40, and the holding of the control holding circuit X7 continues. .
When the recording of the message is finished and the caller hangs up, the VA
Since there is no input to the C circuit XlO and no output from the circuit XlO, the control holding circuit X7 is connected through the line 40.
There is also no input input to the circuit X7, and when the holding time of the circuit X7 (approximately 1 [phase]) has elapsed, the holding of the circuit X7 is released.

Therefore, relays 21, 22, and 23 are released, and the device stops operating and enters a standby state. The standby lamp 9 continues to be lit, but the operation lamp 10 goes out. On the other hand, the incoming call lamp 11 continues to light up, indicating that an incoming call was received while the user was away. Note that by canceling the standby state of the device or operating the release switch, the lamp 1
1 can be erased. If the device temporarily stops operating due to a power outage etc. during automatic response, and the power is turned on again,
Since voltage is supplied to the input line 41 of the relay control holding circuit X4 through the switch S3-2, the circuit X4 operates and the relay 20 is maintained in operation.

Therefore, the responding device operates according to the operation order as described above,
After locating the beginning of the absence notification tape by sensor operation, it stops and enters a standby state. However, in this case, since the relay 23 does not operate and the device is disconnected from the central office line, the contents of the absence notification are not sent. Next, the operation during remote control operation will be explained in detail.

The device has selectors 17, 18,
19 is set to any three-digit number. Remote control is performed during recording of the business. When the device enters the recording state, relays 21 and 22 operate, and their contact G2
operates and supplies voltage to the liner. Control signals identical to the three-digit number determined in advance are transmitted successively in an orderly manner, and when the device receives them, these control signals control the device in the next order and begin rewinding the tape. A bare tone consisting of two signals, a high tone and a low tone, which are control signals, is transmitted from the central office line through a coupling transformer T2 and a liner, and is amplified by an amplifier Xl7, and is then amplified by a filter group Xl8 to select a high tone and a low tone, respectively.
The numbers 0 to 9 are read by the combination of the high tone and low tone that have passed through X24.

This interpretation is performed as follows.

In a connection circuit between selectors X25 to X3O, such as rotary switches, and filter groups X16 to X24, if the first digit signal that has passed through the filter combination corresponding to a specified number matches the connection of the selector, ,
The control circuit X5 is activated by the signal from its output line 42, which operates the control circuit X3l. control. This signal is about 5
held for seconds. Therefore, if the next signal does not arrive within 5 seconds, the previous signal becomes invalid. If the first digit signal does not match the connection of the selector, the control circuit X3l will not operate, and therefore the device cannot be remotely controlled. Next, when the second digit signal that has passed through the filter group Xl8 to X24 matches the connection of the selector, the control circuit X32 operates because input is applied to its input ends 4 and 5, and its output It enters the control circuit X33 via.

This signal is also held for about 5 seconds. If the signal of the second digit number also matches the number set in the device, then receive the signal of the third digit that has passed through the filter group Xl8 to X24, and if the signal matches the connection of the selector , control circuit
33 input ends 4 and 5. Thus, the circuit X3
3 is activated and its output is passed through line 44 to control circuit X.
Enter 34. The output of the circuit X34 is applied to the gate of the silicon-controlled rectifying element SCR2, and since this element becomes conductive, the transistor Tr2 is turned on with a forward bias of 5 applied to its base. When transistor Tr2 is turned on, voltage is supplied to the entire remote control circuit.

Then, a voltage is applied to each input terminal 8 of the control circuits X3l, X32, and X33, and the operation of the circuit changes. In other words, before remote control, when all inputs were applied to each input terminal 3, 4, and 5, an output was generated that was held for 5 seconds after removing the input that was applied to output terminal 6. After that, outputs are generated at the output terminals 6 and 7 only during the time when input is applied to the input terminals 4 and 5. Therefore, during remote control, if a signal of any one of the three digit numbers is sent,
Output terminal 6 of the circuit corresponding to that digit in circuits X3l to X33
, 7, the output appears.

However, only the signal from output 7 is used.
When the transistor Tr2 is turned on, the unwinding state holding circuit X4O enters a state controlled by the charging current of the capacitor CAl3, produces an output from its output terminal 4, and maintains this state. The signal from the output terminal 4 of the circuit X4O is passed through the diode D42 and the resistor R32 to the transistor T.
Joins the base of r5 and turns on Tr5. Therefore, the rewinding plunger P3 operates. The signal at the output terminal 4 of the circuit X4O is simultaneously applied to the base of the transistor Tr6 through the diode D45 and the resistor R28, turning on the transistor Tr6. Therefore, the line and the ground are short-circuited, and the bias of the transistor Trl disappears, and the transistor Trl is turned off. Accordingly, the driving plunger P2 of the message recording side device is turned off, and the pressing of the pinch roller is stopped. Furthermore, the signal at the output terminal 4 is simultaneously connected to the diodes D42 and D42.
35, enters the base of transistor Tr3 through resistor R26, turning on Tr3. Therefore, the relay 24 is activated, and the amplifying section is switched from the message recording state to the message content reproduction state. As a result of the above, the apparatus changes from the message recording state to the rewinding state.

In this way, when the first rewinding state is achieved by remote control, a voltage is applied from the circuit X4O to the input terminals 9 of the control circuits X3l and X33 through the diode D33. Therefore, the circuits X3l and X33 control the first and third digits during rewinding without losing circuit function! You will not be able to control it. Also, during rewinding, the message recording side playback head H3 lightly touches the tape being rewound, and since the amplifier is in the message content reproduction state, the liner hears a sound indicating that rewinding is in progress. J Also, during rewinding, the rewinding state holding circuit X is connected to the input terminal 5 of the automatic rewinding stop circuit X44.
Power is supplied from the output terminal 4 of 4O, and the circuit X44
is ready for operation. The output of a regenerative amplifier is added to the line-o. At this time, the tape is receiving a stop signal of 4.
When the stop signal is rewound to the part where the number is recorded, this stop signal is reproduced, discriminated from other sounds in the circuit X44, amplified, rectified, and DC amplified, and output to the terminal 4 as a DC output. This output is applied to the input terminal 5 of the rewind state holding circuit X4O through the diode D3l, and X4O is restored.
At the same time, the DC output is applied to the input terminal 3 of the reproduction state holding circuit X38, and the circuit X38 is controlled and held in the on state. When the circuit X38 is turned on, a voltage is generated at its output terminal, which is supplied to the base of the transistor Tr3 through the diode D34 and the resistor R26, turning on the transistor Tr3. Therefore, the relay 24 operates, and the input/output signals are switched to a reproducing state. At the same time, the output of terminal 4 of the circuit X38 enters the switch circuit X8 through the diode D5l and the line, thereby switching the power supply of the amplifier from the recording side to the playback side. As described above, the state changes from the rewinding state to the recording content playback state. Further, when the second digit signal is received during rewinding, the control circuit 7X3. An input is applied to the input terminals 4 and 5, and an output is generated at the terminals 6 and 7 as described above. Output from terminal 7 is applied to terminal 5 of rewind state holding circuit X4O through diode D28 to restore circuit X4O, and is also applied to terminal 3 of control circuit X37. When the input signal being applied is cut off, the control circuit X37 operates so that an output appears for a certain period of time from the moment the input signal is cut off. The output generated at the output terminal 4 of the circuit X37 is applied to the input terminal 3 of the reproduction state holding circuit X38, thereby putting X38 into an operating state. Thereafter, in the same manner as described above, the apparatus is changed from the rewinding state to the recording content reproducing state. At this time, the control circuits X3l and X33 recover their functions because the voltage applied to each terminal 9 by the rewind state holding circuit X4O is cut off. When the first digit signal is received during playback of the recorded business content, the control circuit X3l operates and produces an output at its output terminal 7.

This output is supplied to each input terminal 3 of the control circuit X35 and the delay circuit X36. In this case, when the first digit signal is received for a short time, the control circuit X35 operates, and an output is generated from the output terminal 4 for a certain period of time after the input is cut off. This output passes through the diode D29 and is applied to the input terminal 5 of the reproduction state holding circuit X38, and the circuit X38 is restored. At this time, the rewind state holding circuit X4O has already been restored, and no control circuit is operating, and the apparatus enters the recording state. Further, when the first digit signal is continuously received, that is, when a signal is sent to record a stop signal, this signal enters the delay circuit X36.

After a certain period of time after the input is supplied, the circuit
Approximately 2 seconds later), it turns on and an output appears from its output terminal 4. This output enters the re-output state holding circuit X38 through diodes D24 and D29 and restores the circuit X36. Therefore, the message recording state is entered in the same manner as above. At this time, the output of the terminal 4 of the circuit X36 is supplied to the stop signal oscillator Xl4 via the line wire and the diode Dl6. Therefore, the oscillator Xl4 operates and a stop signal is recorded on the tape. If the second digit signal is received during recording of the business, an output appears on the output line 7 of the control circuit X32.

As a result, the control circuit X37 and the reproduction state holding circuit X38
is operated and the device similarly enters the state of playing back the recorded contents of the message. When output appears on selectors X27 and X28, line
A signal appears on line 45 and at the same time diode D appears on line 45.
A signal appears on the line so through 23, and these three outputs enter the switch circuit Xll to turn off the power to the recording amplifier Xl2. This occurs when a control signal is received during recording (as is).
This is to prevent a signal from being recorded on a tape, since there is a risk that it will be played back while the recorded contents of the business are being played back, resulting in a malfunction. That is, even if any of the three digit control signals is received during recording, the recording amplifier Xl2 is immediately turned off. Further, when the third digit signal is received during recording of the business, the recording amplifier X12 is turned off as described above, and the control circuit X35 is operated, and an output appears at its output terminal 7.

The output is applied to the input terminal 3 of the regeneration state holding circuit X38 through the diode D25, which operates to similarly put the amplifier and signal system into the regeneration state. Control circuit X3 at the same time
The output from transistor Tr3 is applied to the base of transistor Tr5 through diode D26 and resistor R32, turning it on. Therefore, the plunger P3 operates only while receiving the signal to rewind the tape. At this time, the output of the control circuit X33 is the diode D26, D, f, and the resistor R
．． Since it is also applied to the base of the transistor Tr6 through 28 and turned on, the pressing of the pinch roller is stopped as described above. When the third digit signal disappears, transistors Tr5 and Tr6 are turned off, and the device enters the state of reproducing the recorded contents of the business. Next, when the third digit signal is received during playback of the recorded contents of the business, rewinding is performed only while the signal is being received, and when the signal disappears, the state of playing the recorded contents of the business is resumed.

There is some DC output on line 46 during all operations other than the recording state, and diode D39 and resistor R2
4. The direct current enters the AC circuit XlO through the line, so the output of the VAC circuit XlO is output during that time. When the second digit signal is received during playback of the recorded contents, (at this time, the playback state holding circuit X38 has already been set, and the recording state holding circuit X39 is supplied with voltage from the output terminal of the circuit X38. ), the control circuit X32 operates,
An output appears at the output terminal 7, which is applied to the input terminal 3 of the recording state holding circuit X39 through the diode D27, thereby controlling the circuit X39.

This causes an output to appear at output terminal 4 of circuit X39. The output from the output terminal 4 is connected to the transistor Tr through the resistor R27.
4, and at the same time turn it on, the timer circuit
Added to 42. Timer circuit X4. When an input is applied to , an output appears at the output terminal 3 for a certain period of time (about 2 to 3 seconds).
The output from terminal 3 is applied to beep tone oscillator X6 through diode D36 and linet, and at the same time is applied to input terminal 3 of control circuit X43 to generate a beep tone indicating the start of recording a new message. The control circuit X43 has the same function as the control circuit X34, and an output is generated at the output terminal 4 for a certain period of time after the input is cut off. This output is applied to relay 25 through diode D38 to operate it. Relay 25 is self-held by contact F4. At the same time, the output of the control circuit X43 is applied to the relay holding circuit X4 through the diode D37, the resistor R25, and the liner, thereby turning on the relay 20 and operating the responding device.
When relay 25 operates, the power supply is cut off by contact F5,
(The playback state holding circuit X38 is held.) The relay 24 is turned off and the device enters the recording state. Furthermore, the recording and erasing heads H1 and H2 are switched from the message recording side to the response side by these recording points f1 to F73. With the above steps, a new message is recorded. Next, when the endless tape goes around, the sensing foil shorts the sensor,
The sensor operating circuit X5 operates, first producing an output on line 37 and generating a beep tone.

Next, at the same time as this output disappears, an output appears on the line 35, which is applied to the relay control holding circuit X4, turns off the relay 20, and temporarily stops the responding device. At the same time, the output produced on line 35 is applied through two to the control circuit X4l. The circuit X4 is a circuit of the same type as the control circuit X34, and produces an output at the terminal 4 for a certain period of time from the time when the input applied to the second circuit ceases. This output is diode D
Terminal 5 of the absence notification recording state holding circuit X39 through 3O
is applied to the relay control holding circuit X4 through the diode D32, resistor R33, and line port to restore the circuit X39 and operate the relay 20 again to operate the responding device. The above recording state holding circuit X39
When the voltage is restored, the transistor Tr4 is turned off and the relay 25 is also turned off. When the relay 25 is turned off, the relay 24 is turned on again by the reverse operation to that described above, and the apparatus is put into the playback state, and the head-related connections are also restored to their previous state. The new message recorded in the above manner is played back.
Next, when the endless tape goes around again, a beep tone is generated in the same way, and the responding device stops.

This time, the control circuit X4l does not operate because the power supply from the contact F5 is cut off. When the relay 20 is turned off, there is no output from the line bench, so the transistor Tr6 is turned off, the pinch roller is pressed again, and the message recording side device is operated. At the time when the automatic check of the recorded contents of the new message is completed, the reproduction state holding circuit X38 is in the ON state, and the apparatus is in the state of reproducing the recorded contents of the message. When recording a new message again, if the second digit signal is received, the above operation is repeated. When the message recording tape ends during message recording, the end switch S6 is turned on and the tape is recorded through the line. A voltage is applied to the loop end control circuit X45.

As soon as an input is applied to the input terminal 3, the circuit X45 generates a DC signal from the output terminal 7, which is applied to the switch circuit X8 through the liner and turns off the power to the regenerative amplifier X9. Also, after a certain period of time, the above circuit X45! A DC signal appears from the output terminal 6 and is applied to the silicon controlled rectifier SCRl through the line ho. Therefore, SCRl is turned on, and the base and emitter of transistor Trl are short-circuited.
l is turned off. Therefore, the plunger P2 for driving the message recording side device is also turned off, and the pressing of the pinch roller is stopped.
When the crimping of the pinch roller is stopped, the switch S6 is turned off. The terminal 3 of the circuit X45 is directly connected to the switch S6, and an output appears at the output terminal 5 while the switch S6 is on. The output is then applied to the beep tone oscillation circuit X6 through the linet to generate a beep tone. The output from the terminal 7 of the circuit X45 is held, and this state continues until an input is applied to the input terminal 4, that is, until the next remote control is performed. Therefore, if there is an incoming call after the business recording tape is finished, the device connects to the central office line, switch S6 is turned on again by detecting the foil on the recording tape, and only a beep tone is transmitted, but there is no call. The notification tape is not played and the operating state is switched in accordance with the control signal only when a remote control signal is sent.

Since the various functions during remote control described above are performed by a combination of the above circuit operations, individual explanations thereof will be omitted. As mentioned above, the automatic telephone answering and recording device with remote control device according to the present invention has many features as follows.

1 By using each bare tone signal corresponding to the numbers O to 9 of each bush button of the bush phone as a control signal, the remote operator can control the bush without any special equipment as bush phones become popular. The phone can be used directly as a control signal transmitter, making it extremely easy to implement a remote control system.

Control signals of arbitrary digits can be set by suitably combining numbers from 20 to 9, and thus many types of setting signals can be formed, and confidentiality can be maintained satisfactorily.

By setting a multi-digit control signal by appropriately combining the numbers 30 to 9, and sending only the signal of the desired digit corresponding to each digit, various types of operation modes can be created to set the device in the corresponding operation mode. operation mode control can be performed reliably.
