Description

DETAILED DESCRIPTION OF THE INVENTION A number of remote listening answering machines are already known.

The present application relates to this type of answering machine, in which the user can remotely listen to the device from a remote location, while remotely listening to or playing back messages written into the device, or if the user suddenly has something to do or needs to contact an important contact person. If you remember and end the call,
It is possible to perform functions that were not possible with conventional devices. In other words, in the past, at the above-mentioned time, the closed circuit would be closed by the timer circuit for a specific evening, and after a certain delay time, the closed circuit would be restored, but the tape would continue to run until the remote control was first operated (hereinafter referred to as the remote control point). The tape was exposed until then, and from that point on, it was put on standby. In addition, as described in Jikai No. 50-154204, if the telephone is disconnected while the contents of the reception tape are being played back by remote control, the reception tape will not be played back until the recorded contents are played back. While driving, in response to calls received during the driving period, only the response terms are sent out to restore recovery, and in response to incoming calls after all the recorded contents of the reception tape have been played back, response terms are sent out. Automatic telephone answering devices are known that prompt recording and switch to recording the caller's voice on a receiving tape. However, since tapes are usually cassette tapes, when using C-60, each side lasts 30 minutes.
For example, if you are away from home for about a week, and if you start from the beginning of the tape and a week later there are messages up to the 29th minute, the owner can call up this message from a remote location and use the first 2 minutes to perform important tasks. There are times when you have a call and need to hang up and contact someone else. When the owner abandoned the phone mid-way, the device soon recovered and the phone's open circuit was released, but the tape continued to run until the 29 minute mark. It will return to standby state later.
Then, even if there is a call from another person for 29-2 minutes, or 27 minutes, incoming calls will not be accepted during that time.
Even if a call comes in after 7 minutes have passed, the tape will be full and only about 1 minute more can be recorded. When the stomach is full, this type of device cannot record the other party's voice. Therefore, in practice, such a device is useless as an answering machine and is impractical. Also,
If you hang up the phone midway through remote listening and then try to listen again using remote control, the receiving tape will be rewound again and played from the starting point once the remote control signal is sent, so you can hear the recorded content that you have already listened to. must be listened to again, and must wait to hear the new recording, which is inconvenient and a waste of time. The present application has been proposed in view of these conventional deficiencies and to improve them.

In other words, the first object of the present application is that in a remote listening answering machine, if the owner abandons the device midway through remote listening, the device will soon be restored, and after that, the answering tape will be used only for answering. The general caller learned that it was not possible to record the caller, and the owner only knew that he had abandoned the call, so he could use remote control to turn over the receiving tape. This makes it possible to continue to remotely listen to the remaining recorded content that was previously listened to remotely without having to go back.

The second purpose of the present application is that the remote control can be applied to the above device either while the response word is being sent or after the receiving tape is running. Our goal is to provide you with the kind of honesty you want. The third object of the present application is that the response tape may use two channels or one channel, but if it uses two channels, the second channel is used as a response-only channel. year,
In addition, in cases where one channel is used, the first half is a response-only message and the second half is a message that prompts the other party to record, and by using such a message, objectives 1 and 2 above can be achieved. There is a particular thing.

The structure and operation of the first embodiment of the present invention will be explained below with reference to FIG. 1.

Evening First, I will explain the main parts.

L1 and L2 are terminals connected to the line, LT is a line transformer for coupling the line and this device, and NE and CdS are photocouplers for detecting a calling signal. Further, 1 is a ringing amplifier for amplifying the calling signal detected by the photocoupler, 2 is an amplifier circuit with a built-in micro fork for amplifying the remote control signal, 3 is a message amplifier circuit, and 4 is the remote controller. It is a tape counter for detecting points, and when the clock goes from "9999" to "0000", terminals 5 and 6 are short-circuited. In addition, 7 is a request signal oscillation circuit that oscillates an audible signal requesting transmission of a remote control signal when the remote control timer described later expires during remote control playback, and 8 is a timer circuit that sets the recording time of a message from the caller. be. Also Y
-1, Y-2, Y-3, Y-4, and Y-5 are relays, and their contacts are indicated as yH, for example. Also T-1
is a response tape on which a response message is recorded, and has a first channel and a second channel.
la is the recording head for the first channel, and RPH-lb is the recording head for the second channel. Also, T-2 is a receiving tape for recording messages from an unspecified number of people.
EH-2 and RPH-2 are the erasing head and recording/reproducing head. Also, M is DC motor 0, and SDI is T above.
-1 is the driving plunger, SD2 is the normal feeding plunger of T-2, SDR is the rewinding plunger, and SDC is a solenoid for resetting the counter to "0000". Also, each ICI to IC14
C is entirely composed of C-MOS. Next, the operation when there is an incoming call from an unspecified number of people will be explained.

When a bell arrives, the neon NE of the photocoupler lights up, in response to which the internal resistance of the photoreceptor CdS decreases, the change is amplified by the IJ ringing amplifier 1, and after a predetermined delay, the transistor QI is connected via the resistor R3. It turns on, energizes the load relay Y-1, and forms a DC loop through its contacts y, -, so the bell stops ringing. At the same time IC
2. To set the flip-flop (hereinafter referred to as FF) of IC3, its Q terminal goes to L level and keeps transistor Q2 on via resistor R4, driving plunger SDI. Since the DC motor M is driven through contacts y and -2, the response tape T-1 starts running, and the response message recorded on the first channel is played back by the green reproducing head RPH-la. , contact y3-,,
It is amplified by the amplifier circuit 3 via y2-2 and y4-2, and further reaches the tertiary winding TH of the line transformer LT via the contact y2-3, where it is induced by the primary winding PR and sent to the calling party. be done. When the response tape T-1 made of endless tape goes around once, the conductor foil P-1 and the electrode CP-1
are in contact with each other, and IC2 and IC3 are connected via the inverter ICI.
Reset the FF. Therefore, Q2 is turned off, plunger SDI is restored, and T-1 stops running, and at the same time, transistor Q3 is turned on by the output of IC3.
Relay Y-2, which is supplied with power through contact yr2, is operated and held in the state, and contacts yM, y2-2, y2-2, y
Switch 2-4 to the make side. Therefore, the plunger SD2 is operated by the contact y2-, and the receiving tape T-2 is activated.
Start running. At the same time, the timer circuit 8 is activated to continuously hold relay Y-1 for a predetermined period of time. Also, contact y2
-2, y2-3 switches the amplifier circuit 3 to the recording state, and the secondary winding SEC of the line transformer LT, the resistor RI9, the contact y2-2, the amplifier circuit 3, the contact y2-3, the resistor R20,
The input message is recorded on T-2 via R21, contact y4-3, and recording/reproducing head RPH-2. Also, contact y2-4
An erase current is caused to flow through the erase head 8H-2. When the timed operation of the timer circuit 8 ends, the relay Y-1 is restored and the relay Y-2 is also restored by switching the contacts y and -2, canceling all operations and completely returning to the standby state. Then, by repeating this operation, messages are stored in T-2. Next, the remote control operation by the owner will be described.

To do so, call this device and then use the response tape T-1.
After switching to the medium or recording state of the receiving tape T-2, a specific key remote control signal is sent out. First T-1
The following explanation assumes that a remote control signal is sent while the vehicle is running. After this remote control signal is amplified by the amplifier circuit 2, the diode D2,
It is rectified by D3 and the charge is accumulated on the capacitor CI. Further, charge is accumulated in the capacitor CII via the buffer IC8 and the diode D5, and the transistor Q7 is turned on via the buffer ICI1 and the resistor R26 to energize the load remote control relay Y-4. At the same time, the FFs of IC6 and IC7 are set by a pulse from the capacitor C4, and the plunger SDC is instantaneously operated via its Q terminal, capacitor C6, and transistor Q5, and the tape counter 4 is reset to "roooo". At the same time, the Q terminal of IC6 is connected to IC12 via capacitor C8.
, sets the FF of IC13 and maintains relay Y-5 in the operating state via transistor Q6. Now, the contacts y4-,, y4-2, y4-3, y4 of the relay Y-4 mentioned above
-4 changes to the make side for the first time, contact y4-. Relay Y-1 is continuously maintained in the operating state via resistor R7, and if the above-mentioned IJ control signal is sent in the recording state of T-2, relay Y-2 is restored and recorded. Release the condition. Further, the contacts y4-2 and y4-3 form a reproducing circuit for the receiving tape T-2. In addition, the plunger SDR is activated by the contact y5- of relay Y-5 to start rewinding T-2, and the counter 4 becomes "0000".
” is reversed. Now, as mentioned above, relay Y-
When T-4 is energized, the playback sound of T-1 is cut off, which confirms that the remote control is working, so the transmission of the remote control signal is stopped at this point. Further, once the capacitor CIO is charged by a remote control signal, this electric charge can hold approximately 6 relays Y-4. Note that during the unwinding, the CIO is continuously charged by the output of the FF IC13 via the diode D4. Next, when T-2 is wound back to the starting point, the conductor foil P-2 and the electrode CP-2 come into contact with each other, so that the inverter IC1
Relay Y-5 is restored to reset the FF of IC12 and IC13 through contact y5-, and plunger SD2 operates through its contact y5-, so the port of T-2 is now released and switches to normal feeding. Here, you can remotely listen to the message recorded on T-2. On the other hand, the response tape T-1 continues to run even during remote control operation, and when the conductor foil P-1 and the electrode CP-1 come into contact with each other during the first rotation, the FFs of IC2 and IC3 are reset, and the T-1 is returned as described above. 1 stops running. That is, cueing of T-1 is performed in order to abandon the program midway, which will be described later. Furthermore, when the above-mentioned capacitor CI0 discharges its charge after about 6 hours, the output of inverter IC9 becomes H level, transistor Q9 is turned off, and DC motor M stops (contact y4- causes DC motor M to output Q9. powered via),
T-2 stops running. At the same time, the output level of IC8 is reached, so charging of CII via diode D5 is stopped. However, in the embodiment, since the charge of CII is maintained for about 5 seconds thereafter, the two inputs of ICIO are both kept at H level and its output is kept at L level for these 5 seconds. During this L level, the request signal oscillation circuit 7 oscillates an audible signal and sends it to the remote control operator. If the remote control operator plans to remotely listen to the remote control point, upon hearing this signal, send the remote control signal within the above 5 seconds and charge the capacitor CIO to continue remote listening as described above. can. Repeating this, the tape counter 4 reaches the remote control point and again changes from "9999" to "00".
00'', terminals 5 and 6 are short-circuited, and input terminal 1 of AND4 is pulled up to H level, and since its input terminal 2 is at H level via inverter IC5, its output 3 is at H level. Then, the FFs of IC6 and IC7 are reset, transistor Q4 is turned off, relay Y-3 is restored, and the system waits for the next remote control operation. At the same time, resistor R28
By turning on transistor Q8 via , transistor Q7 is turned off and relay Y-4 is restored.
At this point, the remote control operation is completely canceled and the device returns to the standby state. That is, during remote listening, the timer circuit 8
This is because the timed operation has ended, and when the contact y4- is restored, the bias circuit of the resistor R7 is cut off and the relay Y-1 is restored. Next, a description will be given of the operation during the above-mentioned remote listening, where the remote listening is not performed up to the remote control point and is abandoned in the middle.

As mentioned above, the receiving tape T-2 has a capacitor CI
Due to the action of O, the audible signal will be sent out for about 5 seconds every 6 seconds and then stop, so at this time, put the handset back and hang up. Therefore, on the device side, capacitor CII discharges its charge after the above-mentioned 6 seconds, turns off transistor Q7 via buffer ICII, and restores relay Y-4. Here, as described above, the bias circuit of resistor R7 is cut off by contact y4-, relay YO-1 is restored, and the apparatus is restored to the special standby state. That is, the difference from the case of remote listening to the remote control point described above is that IC6, I
The FF of C7 has not been reset. Therefore, the transistor Q4 is turned on by the Q output, and the load relay Y-tor3 is kept in an operating state, and its contacts y3-, y3-2 are switched to the make side. first,
Contact point y3- causes the second response tape T-1 to
The channel head RPH-lb is connected, and the base of the driving transistor Q3 of the 0 recording relay Y-2 of the receiving tape T-2 is grounded by the contact y3-2. Therefore, if there is an incoming call from an unspecified number of people in this state, the second channel on T-1 will be reproduced, and this T-1 will go around once to connect the conductor foil P-1 and the electrode CP-1.
When the FFs of T-IC2 and IC3 are reset, the plunger SDI is restored as described above and T-1 stops running, and at the same time, the Q of IC3 becomes H level and the resistance increases. Even if bias current flows through R8, relay Y-2 is energized by contact y3-2 and there is no 0.
Since T-2 does not run, the bias circuit of resistor R6 is cut off and relay Y-1 is restored after one cycle of T-1.
The device returns to the special standby state described above. Next, a description will be given of the process by which the owner turns on the remote control and listens to the playback after abandoning the device.

For this purpose, the device is called and a remote control signal is sent out during the above-mentioned second channel reproduction. At this time, as mentioned above, IC12 and IC13 at the female point of the receiving tape T-2.
Since the FF has already been reset, relay Y-5 is off, and when the remote control signal is sent in this state, relay Y-4 is energized as described above, making contact y4-, make contact, and contact y5-. Since the plunger SD2 for normal feeding is energized through the break contact of , it is possible to remotely listen to the message after the previous abandonment.
Then, as described above, when remote listening is performed to the remote control point, the FFs of IC6 and IC7 are reset, relay Y-3 is restored, T-1 is switched to the first channel, and the complete standby state is restored. Note that in this embodiment, the case where T-1 is divided into two channels has been described; however,
As another example, T-1 is made into one channel, a response-only message is recorded in the first half, and a message prompting for recording is recorded in the second half, and when the above-mentioned abandonment occurs, the message is broadcast to the first half of this T-1. It can be configured to reproduce and send only the response-only message that has been received.

This will be explained below with reference to FIG. In other words, in this case, the first
The green head RPH-lb and the resistor R6 shown in the figure are no longer needed, a timer circuit 9 is added in place of R6, and the arrangement of the contact y3- of the relay Y-3 is changed. Further, a circuit example of the above-mentioned timer 9 is illustrated in FIG. Further, a resistor RI02 is added to expose the face of T-1. That is, as described above, if the remote control operation is abandoned midway, the IJ Ray Y-3 is maintained in the operating state. When an incoming call is received in this state, relay Y is sent via ringing amplifier 1.
-1 is energized to form a loop circuit, and at the same time, the response tape T-1 starts running and begins reproducing the response words.
At the same time, power supply to the timer circuit 9 is started from the collector side of the transistor Q2 which is turned on. In this timer circuit 9, the emitter side of the transistor QIO shown in FIG. 3 and one end of the capacitor CIOO are grounded through a contact y3-. Therefore, capacitor CIOO is gradually charged via ladder R100, and when CIOO reaches a predetermined charging voltage value, for example after a few seconds, QIO is turned on. Therefore, the bias that was holding relay Y-1 through resistor RIO1 and diode DIOO transistor QI is cut off, and IJ relay Y-1 is restored, so the loop is released and the response term is the response-only message at the beginning. Interrupted. On the other hand, the remaining part of the response tape T-1 continues to run through the FFs of IC2 and IC3 as described above, and when the conductor foil P-1 and electrode CP-1 come into contact with each other in the first rotation of T-1, the above-mentioned T-1 by resetting the FF of
will automatically stop running. In other words, the beginning of T-1 is automatically searched, and during this time transistor QIO is on, so even if there is an incoming call during this time, relay Y-1 is not energized and the response is always from the beginning of T-1. Since it only plays the dedicated message, the general user knows that the device cannot record messages from outside, and the user realizes that the device has been abandoned before, so the remote control cannot be used. By canceling this, it is possible to reproduce and listen to T-2 from that position in the same way as described above. As described above, the present invention improves the shortcomings of the prior art, and does not listen to the entire recording content recorded on the receiving tape during remote listening, that is, the recorded content of the receiving tape up to the point where remote control is performed. Even if you hang up the phone to listen, you can call up this device again and remotely control it to listen to the continuation of the recording that was recorded on the receiving tape you were listening to earlier. This eliminates the waste of time and inconvenience of being able to listen to continued recording content only after listening to the recorded content that has been remotely listened to again, and is very convenient especially when listening remotely from a public telephone where time is limited.
