Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to an answering machine having a function of remotely monitoring sounds in a room while the user is away.

(Prior art and its problems) In the conventional remote control of this type of device, business messages,
The only thing you can do is record and play back messages, etc., or force the phone to ring if it is known that you are not home, and what happens to the situation at the place where it is installed while you are away. There was no way to know if they were there.

(Purpose of the invention) The present invention monitors the sounds in the room while the user is away by activating the microphone circuit of the device by remote control after automatically answering an incoming call, and outputting the surrounding sounds where the device is installed to the line side. To provide a remote control system for an answering machine, which enables communication with a person in the room by remote control by transmitting a signal on the line side through the speaker of the answering machine.

(Structure and operation of the invention) The present invention will be explained in detail below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which 1 is a telephone line terminal;
2 is a hook switch, 4 is a telephone network, 5 is a transmitter, 6
is a telephone receiver, 7 and 33 are signal transformers, 8 is a recording amplifier, 9 is a reproduction amplifier, 10 is a microphone, 11 is a speaker, 12 is a voice detection circuit, 13 is a remote control signal receiving circuit, 14.15.16.17 is an analog gate, 18.1
9 is a relay, 3 is a contact of relay 18, 31 is a relay 19
20 is a control circuit such as a 1-chip CPU, 21.2
2 is the head, 23.24 is the tape, 25', 26 is the motor, 27.28 is the cassette tape 23.24, respectively.
29 is an operation switch, 30 is an incoming call detection circuit, and 32 is a tone generation circuit.

Next, the operation of this embodiment will be explained. First, the response message is recorded. By operating the operation switch 29, the control circuit 20 starts the motor 25 to start recording the response message, and when the rotation detection circuit 27 completes the cueing of the response message. Start recording the audio signal from. The audio signal is recorded on the tape 23 via the path [microphone 10 - analog gate 15 - recording amplifier 8 - relay contact a 31 - head 21]. Incidentally, the cue of the response message is performed by the rotation detection circuit 27 and the control circuit 20 corresponding to the take-up reel of the tape 23. First, prior to recording, the control circuit 20 rotates the motor 25 in the rewinding direction to find the beginning of the tape. The beginning of the tape is determined when the reel stops rotating and the rotation detection circuit rough output is no longer output.Next, the control circuit 2
0 sends the tape 23 for a certain period of time while running at a constant speed, sets that as the beginning of the response message, and records messages thereafter. This operation is similarly performed when automatically responding to an incoming call and when waiting at the beginning of a response message.

Next, we will explain how to record a message when a call arrives. When the incoming call detection circuit 30 detects an incoming call signal from the central office line and the control circuit 20 determines that the incoming call is incoming, the relay 18 is activated. As a result, the relay contact 13 is turned on and a DC loop is formed for the line. When the line is closed, the control circuit 20 starts the motor 25 and sends out a response message from a predetermined standby position. The response message is sent by pinking up the signal on the tape 23 with the head 21, and sending the signal from the relay contact a31 to the regenerative amplifier 9 to the gate 16 to the transformer 33.
→Speech network 4 - relay contact 13] is sent to the line terminal 1. The end of the reproduction signal of the response message is detected by the voice detection circuit 12, and the control circuit 20 operates the relay A19 and the motor 26 to start recording the message.

Here, the end of the response message can be realized by recording a control signal in advance when recording the response message. In addition, the business message is transmitted by supplying the signal from the line terminal 1 to the tape 24 via the path of [relay contact 7!3-transformer 7-gate 14-recording amplifier 8-relay contact a31-head 22]. be recorded. When the caller finishes recording the message and goes on-hook, a call termination signal (busy tone) is sent to the central office line. This signal is detected by the voice detection circuit 12, and the control circuit 20 ends the recording operation and sends the message to the relay 18. The relay A19 is restored, the response message is cued, and preparations are made for the next incoming call.

Next, the operation of remote control will be explained. During the above-mentioned automatic call response, the remote control signal receiving circuit 13 monitors the remote control signal from the line. If, for example, an MP multiplied signal of a telephone is used as a remote control signal, 13 is an MF signal receiving circuit. When a remote control signal is received, for example, if the signal is a signal for reproducing a business message, the control circuit 20 starts the motor 26, brings out the beginning end of the tape 24 on the business side, and after the beginning end comes out. The tape 24 is put into a playback state, and the message recorded on the tape 24 is sent out to the line side. here,
The start end of the message tape 24 is detected by the rotation detection circuit 28 in the same manner as the start end of the response message tape 23 described above. In addition, the final position of the business tape 24 can be determined when the number of revolutions when the start end is taken out and the number of revolutions during the playback operation are lost, and the playback operation is ended at this position and the next control is started. Waiting at the signal.

Here, the operation during remote control in the present invention will be explained. Assume that the remote control signal was defined as follows in the previous explanation of remote control.

<il Password number: 匪■■匪 (DI is a two-digit number that can be arbitrarily set by the owner of the device, and here, it is assumed that it is set to "12" as an example.

Next, when control signals such as fi) to - are input, the device performs operations according to the respective signals. This is a remote call and indoor monitor signal for the can.■
(6) When the tone generating circuit 32 is received, the tone generating circuit 32 is operated for a certain period of time and its output is outputted from the speaker 11 via the path [amplifier 9 - gate 17]. After that, the control circuit 20 controls the signal from the line to [line terminal 1 - relay contact A].
3-transformer 7-gate 14-recording amplifier 8-reproducing amplifier 9-gate 17]. When a certain period of time, for example about 30 seconds, has elapsed in this state, the control circuit 20 activates the microphone circuit and sends the sound collected by the microphone 10 to the line. The signal is [microphone 10 - gate 15 - recording amplifier 8 - playback amplifier 9 - gate 16 → transformer 33 →
The communication circuit yj4--relay contact 13--line terminal 1] is sent out through the route. When a certain period of time, for example about 30 seconds, has elapsed in this state, the speaker 11 is switched to the above-mentioned speaker 11. Thereafter, a conversation can be made by alternately switching between the microphone 10 and the speaker 11.

FIG. 2 is a flowchart showing the above control operation, and shows the case where the monitoring time is 30 seconds.

By doing this, you can know the internal state of the house while you are away, so for example, if you go shopping while your child is sleeping, you can see what the child is doing from outside. You can also talk to your child if they wake up and cry.

In addition, although the above explanation has been made on the assumption that calls will be made alternately in view of howling, simultaneous calls will be possible if the telephone answering machine is equipped with a hands-free call function.

(Effects of the Invention) As explained above, according to the present invention, it is possible to know the internal state of the house while you are away by remote control by monitoring the surrounding sounds from the microphone, so it is not only useful for children but also for children. When a bedridden elderly person or a sick person leaves behind, this system has the advantage of being useful for alleviating anxiety and being able to obtain information on the go.
