Abstract

PURPOSE:To report only the number of times of incoming from calling subscribers, by counting down the counting value of a counter circuit by ''1'' at the time of receiving operation when a remote subscriber sends a remote control signal. CONSTITUTION:When a calling signal arrives under the waiting condition, the message of the called subscriber is recorded after closing a telephone line and an answering message is called and sent, then, the waiting condition is restored. When an incoming operation is performed thereafter, the counting value of the 1st counter circuit 5 is added to the counting value before the remote calling is made and the counting value is increased. Therefore, when a remote control signal is sent next, the counting value of the 1st counter circuit 5 is preset in the 2nd counter 11. Therefore, the number of an audible signals is obtained by adding the number of newly incomings to the number of incomings at the 1st operation time to be sent to a remote subscriber.

Description

Detailed Description of the Invention (a) Industrial Application Field The present invention provides an automatic answering machine having a remote listening function that allows a message from a caller recorded on a recording tape to be listened to from a remote location. Regarding.

(b) Prior art automatic answering machine responds to a call signal coming from a telephone line, performs an incoming call operation, sends a response message recorded on a response tape to the caller, and then responds to a call signal from the caller. It has a function to record messages on a recording tape, but recently, in addition to this function, there is a so-called remote control that allows the message from the caller recorded on a recording tape to be played back and listened to at a remote location. Automated answering machines with a listening function are becoming popular.The remote listening operation of such an automatic answering machine with a remote listening function involves rewinding the recording tape using a remote control signal and then switching to the playback mode. It is done by
If the number of messages recorded on a recording tape can be recognized during remote listening operation, the remote listener will be able to know the time required to listen to the messages, which will be extremely convenient. A technique for notifying a remote listener of the number of calls received while one is away is described in Japanese Patent Application Laid-Open No. 18311/1983, but in this technique, incoming calls are also counted for remote listening operations. Therefore, the count value by the counter circuit is the number of calls received from the remote listener in addition to the number of calls received from the caller. If there is one remote listener, the number of incoming calls from the caller can be recognized by subtracting the number of incoming calls for remote listening, but if there are multiple remote listeners, the number of incoming calls can be recognized. I can't.

(C) Purpose of the Invention The present invention provides an automatic answering machine configured to notify a remote listener of the number of incoming calls during remote listening operation.
The present invention attempts to provide a device that notifies only the number of incoming calls from a caller.

B) Structure of the Invention The present invention provides a counter circuit for counting the number of incoming calls, and an audible signal generating circuit for transmitting a number of audible signals corresponding to the count value of the counter circuit to a remote listener during remote listening operation, When a remote control signal is sent during remote listening operation, the count value of the counter circuit is decremented by 1.

This is a second counter circuit in which the count value of the counter circuit (5) is preset, and includes a down terminal 04) and a plurality of output terminals α5). The input terminal of θ6) is connected to the output terminal (10) of the delay circuit (9), and when a control signal is output from the output terminal (0) upon reception of a remote control signal, it performs an inverted operation and is in that state. When the inversion holding circuit (16) is inverted to the operating state, the inversion holding circuit 0η operates to oscillate and outputs a pulse signal at the H (high) level for a predetermined period, for example, 0.5 seconds, and the L (low) level for 1 second. A first oscillator (184-!, a second oscillator that outputs an audible signal, outputs an audible signal every time a pulse signal from the first oscillator Q?) is applied, and a controller (184-!) outputs an audible signal.
2) to a remote listener. Further, the pulse signal from the first oscillator αD is applied to the down terminal θ of the second counter circuit 01),
It has the effect of causing the count value preset in the second counter circuit Q11 to count down.

The input terminal is connected to the output terminal (15) of the second counter circuit 01), and the output terminal is the reset terminal of the inversion holding circuit 06) and a message from the caller is recorded. It is connected to the control terminal of a rewind control circuit that rewinds the recording tape being played. Further, (21) is a reset switch for returning the count value of the first counter circuit (5) to zero.

The automatic answering machine of the present invention is constructed as described above, and its operation will be described next. In the standby state and in the state in which the remote listener does not send a remote control signal, the inversion holding circuit (161 is in a non-inversion state, the first oscillator αη, the second oscillator
The oscillator (181 and the rewind control circuit) are in a non-operating state.In the standby state, when a ringing signal arrives, the incoming call circuit that constitutes the control unit (2) operates to establish a connection with the telephone line and use the response A predetermined operation is performed in which the response message recorded on the tape is sent to the caller, the message from the caller is recorded on the recording tape for a predetermined period of time, and the caller returns to the standby state.In this way, the response recording operation is performed. is performed, but when the incoming call operation is performed, the control unit (2)
A count signal is outputted from the first terminal (3) of and applied to the up terminal (6) of the first counter circuit (5), so that the first counter circuit (5) performs a counting operation. Every time a response recording operation of the automatic answering machine described above is performed, a count signal is output from the first terminal (3), and the first counter circuit (5) counts the number of times.

As described above, the normal response recording operation and the counting operation of the number of incoming calls by the first counter circuit (5) are performed, but next, the remote listening operation will be explained.

When the remote listener calls the automatic answering machine to listen to the message recorded on the recording tape from the caller, an incoming call operation is performed and the first counter circuit (
The count value of 5) is incremented once.

When the remote listener sends a remote control signal after the incoming call operation is performed, the first control part signal is output from the second terminal (4) of the control part (2), and this control signal turns the first counter circuit (5) down. When a control signal is applied to the down terminal (force and delay circuit (9) of said first counter circuit (5), said first counter circuit (5)
The count value of the first counter circuit (5
) is the count value before performing remote listening, that is, the number of incoming calls from the calling party. After the down-count operation of the first counter circuit (5) is performed, the delay circuit (
A control signal is output from the output terminal (10) of the second counter circuit 01), and the control signal is applied to the preset enable terminal 0 (and the inversion/holding circuit (16)) of the second counter circuit 01).

When a control signal is applied to the preset enable terminal (+31) of the second counter circuit αυ, the count value counted by the first counter circuit (5) is preset to the second counter circuit (11), and the preset value is A signal corresponding to the count value is output from the output terminal (151). When an H level signal is output from the second output terminal a of the second counter circuit aυ, the NOR circuit (II of The output becomes L level. When the control signal from the output terminal 00 of the delay circuit (9) is applied to the inverting holding circuit end, the inverting holding circuit aO is inverted to the operating state. The inverting holding circuit Oe is When reversed to the operating state, the first oscillator 07) enters the operating state and outputs a pulse signal at a predetermined period.The pulse signal output from the first oscillator 07) is applied to the second oscillator
As a result, the second oscillator α outputs an audible signal every time a pulse signal is applied. The audible signal output from the second oscillator 0 is sent to a remote listener through the control unit (2). Further, the pulse signal from the first oscillator 07) is applied to the down terminal (14) of the second counter circuit 0υ to cause the count value of the second counter circuit 01) to count down. The second counter circuit (11
) is performed and the count value of the second counter circuit α1) becomes zero, all outputs of the output terminal 02 become L level, so the output of the NOR circuit a1 is inverted from L level to H level. As a result, the inversion holding circuit (16) is reset and returned to the non-operating state, and accordingly, the first oscillator (1?) and the second oscillator (18) become inactive and transmit information to the remote listener. No audible signals are transmitted. Further, when the output of the NOR circuit αa is inverted from the L level to the H level, the rewind control circuit to which this signal is applied is inverted to the operating state and starts rewinding the recording tape on which the caller's message is recorded. Let's do it. Therefore, the number of audible signals sent to the remote listener upon reception of the remote control signal is determined by the number of audible signals sent to the remote listener in accordance with the first counter circuit (α1) preset in the second counter circuit α1).
The count value of 5) is the number of incoming calls from callers who previously called while the user was away, and the remote listener can recognize the approximate number of messages before starting the message listening operation using the remote control. After the recording tape is rewound, a well-known remote listening operation is performed and the automatic answering machine returns to the standby state.

As described above, when the remote listener sends out a remote control signal, the count value that was being counted in the first counter circuit (5) is preset in the second counter circuit (10, and the second counter circuit 01). The count value is down-counted and the second counter circuit (1
Although the count value of step 1) returns to zero, the count value of the first counter circuit (5) does not change. Therefore, when an incoming call is performed after the remote listening operation is completed and the standby state is returned, the first counter circuit (5) performs a counting operation, and the count value of the first counter circuit (5) is the count value before remote listening. is added to and increases. Therefore,
Next, when the remote listener sends out a remote control signal to perform a remote listening operation, the above-mentioned operation is performed, and the count value of the first counter circuit (5) is changed to the second counter circuit aυ.
is preset to . Therefore, the number of audible signals obtained by adding the number of new incoming calls in addition to the number of audible signals during the first remote listening operation will be sent to the remote listener.

As a result, the remote listener is able to perceive an approximate number of all messages recorded on the recording tape. Furthermore, when the reset switch CD is closed, the first counter circuit (5) is reset and its count value becomes zero.

In this embodiment, the recording tape is rewound by the rewind control circuit (20) which operates in accordance with the inversion of the output signal of the NOR circuit Ql. After counting the number of audible signals, the remote control signal It is also possible to perform the rewinding operation by sending out the .

(F) Effects of the Invention The present invention is configured so that when a remote listener sends out a remote control signal in order to perform remote listening, the remote listener sends out as many audible signals as the number of incoming calls. The approximate number of messages present can be recognized before performing a remote listening operation, which is extremely convenient.

Furthermore, when a remote control signal is sent to perform a remote listening operation, the count value of the counter circuit is decremented by 1, so incoming calls for remote listening are not counted, and the count value of the counter circuit is the number of incoming calls from the caller. Therefore, the present invention is extremely effective when a plurality of people perform remote listening operations.
