In the device shown in Figure 1, calls are made from telephone 2 in the same way as in normal cases, but in the case of an incoming call, normally calls 3 to 8 are kept inactive unless the call is set to automatically answer in advance. telephone 2 makes a ring tone. When the receiver learns of the call from this sound and wants to make a call, he picks up the handset of the telephone and makes the call, but if he is unable to answer the call for some reason, he directly operates the automatic answering recorder 3. Alternatively, a control signal is sent from the remote control operation unit 6 to start the automatic answering recorder 3 and receive an incoming call. In this case, the answering call is sent to speaker 7.
It can be monitored at A more specific circuit configuration for performing the above operation is shown in FIG. 3, for example, and will be explained later.

FIG. 2 is a block diagram of another example of the circuit configuration of the device of the present invention, in which remote control is performed by wireless transmission. In this case, the connection line 8 is not required, but the automatic answering recorder side is equipped with a wireless transceiver 9 and an antenna 10 for receiving control signals necessary for remote control and sending out monitoring audio signals, and the remote control section is also controlled. It is necessary to add a radio transceiver 12 and an antenna 11 for signal transmission and monitoring audio signal reception, respectively. However, the remote control unit, including these, should be movable as desired, and the limits of remote control are determined by the performance of the wireless transmitter/receiver including the antenna, the distance of transmission and reception, the situation, etc.

Next, the operation of the apparatus of the present invention in the case of FIG. 1 will be explained with reference to FIG. In this figure, a telephone is also connected to the telephone line 1, but is not shown. The portion to the left of the two-dot chain line in the center of the figure is a circuit of a conventional automatic answering recorder and a circuit added thereto. First, 22 is a switch SW ₁ that connects the automatic answering recorder to line 1 by remote control, 23 is a manual switch SW ₂ when the automatic answering recorder is set to receive incoming calls in advance, and 24 is a remote control switch. When waiting for operation, the power switch SW ₃ of the connecting part 4, 25 is the power supply circuit PS ₂ of the controlled part 4 which is activated when SW ₃ is turned on, and 26 is the power supply circuit PS ₁ of the automatic answering recorder. Power is supplied from power supply 31P ₀ . In addition, PS ₁ has the DC power required for the automatic answering recorder and its additional circuits.
Supply D ₀ .

27 is an OR gate circuit which drives a relay 28RL1 and turns on the switch _SW1 of ₂₂ when a remote control input or a call detection control input is received from the controlled unit 4. 29 is a circuit D ₁₆ that detects an incoming ringing signal (16 Hz); 30 is a detection circuit DH that starts operating at the detection output of D ₁₆ , receives this output and outputs a response; a response circuit 34 that closes when the response of TRP is completed; 32 is a relay that turns on switch 33SW ₄ when receiving the detection output of the detection circuit 30.
RL ₂ and switch SW ₄ connect the telephone line 1 and the hybrid transformer 35HT while the detection circuit 30 is in operation to form a line loop. This hybrid transformer

is a remote control machine, 5, 6, 7 in Figure 1
Contains. i.e. remote reception switch SW ₅ ,
Contains lamp L and speaker SP.

Next time, when using this device for remote control reception, turn off the switch SW ₂ (and SW ₁ ) so that the telephone 2 will receive the incoming call. In such a state, the incoming ring tone is generated from the telephone and the user can know that the call is ringing. Therefore, when the recipient is unable to pick up the telephone, the following operation is performed with reference to FIG. 3 to receive and record the other party's message in the same way as an answering machine.

First, it is necessary to turn on the power switch SW ₃ of No. 24 (hereinafter referred to as 24SW ₃ ) in advance, and when the user hears the ringing tone of the telephone, turns on (closes) the remote reception switch SW ₅ . As a result, the relay _28RL1 is activated via the relay 270R, and the switch _22SW1 is turned on, and the incoming call signal is sent from the telephone line 1 to the call detection circuit _29D16 , and the detection output starts the operation of the call detection circuit 30DH. This operation activates the power supply 26PS, maintains the output of the detection circuit 30DH in an operating state, and also turns on both the relay 28RL ₁ via the relays 32RL ₂ and 27OR. This relay RL ₂
When the switch SW ₄ is turned on, the telephone line 1 is terminated by the hybrid transformer HT and a loop circuit is formed on the receiving side, thus making it possible to communicate with the calling side. The output of the detection circuit 30DH also drives the response circuit 34TRP, and the response output is sent to the hybrid transformer HT, switch _SW4 , switch
It is sent to telephone line 1 through SW ₁ . Furthermore, at the same time, the output of 30DH is the incoming call recording circuit 36.
The RRP is also driven to record answered and incoming calls, and a part of the output of the amplifier is given to the speaker SP of the remote control unit 37 via the amplifier or combined output circuit A of the controlled unit 4 and the communication line 8. Note that the third output of the detection circuit 30DH is connected to the remote control unit 3 through the controlled unit 4 and the communication line 8.
7 lights up to indicate that a call is in progress. When the indicator lamp L is turned on in this manner, the receiver near the remote control unit 37 returns the switch SW ₅ to turn it off. At this time, the switch _SW1 is maintained in the on state because the output of the detection circuit 30DH is continuously applied to 27OR. Also, when there is no incoming call signal or if the incoming call signal does not continue after switch SW ₅ is turned on and SW ₁ is turned on, the detection circuit 29
Since the detection of _D16 and the start of operation of 30DH are not established, a closed loop of the telephone line 1 is not established. The above is the process leading to call recording and simultaneous monitoring in the remote control unit.

Next, in order to terminate the call and open the loop, the response circuit 34TRP is provided with a signal circuit that outputs a termination signal at the end of the endless response tape. The response circuit 34 sends an end signal to the detection circuit 30 to close the operation of the detection circuit 30DH after the time call.
Send it to DH and stop the detection operation that was continuing until then. The outputs when the detection operation of the detection circuit 30 is stopped are the power supply PS ₁ , the relays RL ₂ , RL ₁ , the response circuit 34TRP, the recording circuit 36RRP, and the display lamp L.
respectively, to close or restore operation. However, the response circuit is stopped in the next standby response state, and the recording circuit is stopped in the state where the next recording can be continued. Also, switches SW ₁ and SW ₄ are clearly turned off and the telephone line loop is released.

Note that when a call is made from the telephone set 2 or during a call from the telephone set 2, the calling signal detection circuit _29D16 does not respond, so this automatic answer recording device does not operate. Furthermore, even if the switch SW ₅ or SW ₂ is turned on during a call or conversation from the telephone 2, the detection circuit 29D ₁₆ does not respond, so the automatic answer recording device does not operate.

Next, a case where the transmission line 8 is replaced with wireless transmission as shown in FIG. 2 will be described. 9 and 12 are micro power transmitters and receivers of arbitrary frequencies; 10 and 11 are transmitters;
Although it is a receiving antenna, it is natural that the transmitting and receiving frequencies of 9 and 12 are exchanged values. To perform transmission from the transmitter/receiver 9, the transmitter/receiver 9 receives a call display signal output from the detection circuit 30DH of FIG. 3, and controls the transmitter output so that it is turned on while this signal continues. In addition, the response output from the recording circuit 36RRP in FIG. 3 and the incoming call monitor pass through the amplifier circuit A of the connection unit 4 and become the transmission modulation input of the transceiver ₉ in FIG. . When the transmitter/receiver 9 is in the standby state after _the switch 24SW ₃ shown in FIG. The switch in Fig. 3 detects only the
Perform the same operation as when SW ₅ is closed.

On the other hand, if switch SW ₅ of the operation unit 6 is turned on on the remote control unit side, the transmitter/receiver 12 will transmit a carrier frequency ₂ modulated with a specific signal or frequency.
The transmission power is radiated from the antenna 11, received by the transceiver 9, and operates as described above. Also antenna 1
When the radio wave from the 0 side detects the arrival of the carrier wave ₁ , the display lamp L of the operation unit 6 (37L in Fig. 3) is activated.
It will be easily understood that the telephone is turned on and _one wave of demodulated audio output is supplied to the speaker 7 to monitor and receive the call in progress.

As explained in detail above, according to the device of the present invention, when a ringer is heard but the telephone cannot be answered directly, an automatic answering recorder (answering machine) is activated by a remote control circuit using wired or wireless transmission. Since the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be operated, the telephone answering machine can be made to reply to the recorded matter, the telephone message of the other party can be recorded, and the contents can be monitored at the same time.
