And a power supply circuit 20 for supplying power to each unit (each circuit).

The indoor master unit 2 has a control circuit (hereinafter referred to as master unit CP).
U) 30, a call detection circuit 31 for detecting a call from a visitor of the entrance device 1, and a television monitor 32 for outputting (reproducing) an image taken by the television camera 13 of the entrance device 1. When a ringing sound speaker 33 connected to a receiving amplifier 38 for sounding a ringing sound to notify a resident of a call from the visitor of the entrance cordless handset 1 and a troublesome call by the visitor are repeated. A refusal button 34 to be pressed, a voice message IC 40 for sending a message from the entrance cordless handset to encourage the visitor to return home by the pressing operation, and a reception used by the resident to establish a call with the visitor. A handset 35 to which an amplifier 38 and a transmission amplifier 39 are connected, and a hook-up for detecting a hook-off when a response operation such as picking up the handset 35 is performed by a resident. And the flop detection circuit 36, the handset 3
5 and a communication path switching circuit 37 that forms a communication path between the speaker 16 and the microphone 17 of the entrance device 1 via the line L1.

A first input terminal P1 of the slave unit CPU 10 of the entrance slave unit 1 has one end of a call button 11 having the other end connected to a reference potential point, and a second input terminal P3 has a power supply circuit 20.
However, a line connection terminal T1 to which the line connection terminal T2 of the indoor master unit 2 is connected via the line L1 is connected to the input / output terminal P6. The television camera 13 is connected to the line connection terminal T1 via the power supply circuit 20, and the speaker 16 and the microphone 17 are connected to the line connection terminal T1 via the reception amplifier 18 and the transmission amplifier 19, respectively.

A first input terminal P11 of the main unit CPU 30 of the indoor main unit 2 has an output side of the call detection circuit 31 whose input side is connected to the line connection terminal T2, and a reject button 34 has a second input terminal P12. The third input terminal P13 has a hookup detection circuit 36 connected thereto, the first output terminal P14 has a line connection terminal T2 connected thereto, the second output terminal P15 has one end connected to the line connection terminal T2, and the other end connected. Is connected to a ringing speaker 33 via a reception amplifier 38 and a transmission amplifier 39 and a control input side of a communication path switching circuit 37 connected to a handset 35, respectively, and a third output terminal P16
Has one end connected to the voice message IC 40 connected to the line connection terminal T2.

The operation of the thus configured television monitor device will be described below. When a visitor performs a naughty calling operation such as repeatedly pressing the call button 11 of the entrance slave unit 1 at the time of calling to call a resident in the dwelling unit, the slave unit CPU 10 sets the first input terminal P1.
, The above-described calling operation is detected, and a calling signal S1 is continuously output from the input / output terminal P6. The call signal S1 is input to the call detection circuit 31 via the line connection terminal T1, the line L1, and the line connection terminal T2 of the indoor master unit 2. The call detection circuit 31 calculates the following from the continuously input call signal S1.
At a predetermined time, a call detection signal S2 that detects a continuous call from a visitor of the entrance slave unit 1 is output to the base unit CPU 30.

The base unit CPU 30, which has detected the call detection signal S2 through the first input terminal P11, continuously outputs a call sound signal S3 for sounding the ring sound speaker 33 from the second output terminal P15. At the same time, a voltage signal S4 for increasing the voltage of the line L1 from 8V to 15V is output from the first output terminal P14. The ringing tone signal S3 is amplified by the receiving amplifier 38 through the call path switching circuit 37 in the standby state, and is continuously sounded as the ringing tone by the ringing tone sounding speaker 33. An annoying call due to a continuous call operation of one visitor is notified. The voltage signal S4 is supplied to the slave CPU 10 via the line connection terminal T2, the line L1, and the line connection terminal T1 of the entrance slave 1.
Is input to the input / output terminal P6. The video signal S20 captured by the television camera 13 is supplied to the power supply circuit 20, the line connection terminal T1, the line L1, and the line connection terminal T2 of the indoor master unit 2.
Is displayed on the television monitor 32 through the interface, the resident can confirm (identify and confirm) the image of the visitor and the vicinity of the entrance of the dwelling unit.

Here, the continuous ringing sound (ringing signal S3) ringed by the ringing sound ringing speaker 33 and the video (video signal S20) output on the television monitor 32 are used to make the entrance slave 1 When the resident who has confirmed the annoying call by the continuous call operation of the visitor of the person presses the reject button 34 to stop the visitor from calling,
The input signal S of this pressing operation is input via the second input terminal P12.
The master CPU 30 that has detected the first output terminal 11 outputs the third output terminal P16
Sends a voice message control signal S7 prompting the visitor to return home. By pressing the refusal button 34, for example, by pressing it long for a certain period of time, or by pressing it shortly many times, the type of signal input to the base unit CPU 30 differs.
Base unit CPU 30 receives input signal S1 from reject button 34
By changing the output signal S7 to the voice message IC 40 according to 1, the voice message IC 40 sends a different voice message S8 prompting the visitor to return home. This voice message S8 is sent to the line connection terminal T2 and the line L
1. Input to the reception amplifier 18 of the slave unit via the line connection terminal T1 of the entrance slave unit 1, sound the speaker 16, and output the voice message S8 to urge the visitor who has made an annoying call to return home. be able to.

Further, in order for the resident in the dwelling unit to answer the visitor who made the above-mentioned annoying call and establish a call, the hook-up detection circuit 36 detects the hook-off by picking up the handset 35, A hookup detection signal S9 is output to master unit CPU 30. Base unit CPU 30 that has detected hookup detection signal S9 via third input terminal P13 outputs control signal S10 for activating communication path switching circuit 37 from second output terminal P15. The handset 35 used by the occupant is activated by the activated and switched communication path switching circuit circuit 37.
And the receiving amplifier 38 and the transmitting amplifier 39, the communication path switching circuit 37, the line connection terminal T2, the line L1,
A communication path is formed between the speaker 16 and the microphone 17 via the line connection terminal T1, the reception amplifier 18 and the transmission amplifier 19, and the voice signal S30 can be transmitted and received via this communication path. The call with is established.

In the above-described embodiment, a message for prompting an annoying visitor to return home has been described from the entrance slave unit. However, a timer is set in the CPU of the indoor master unit, and after a certain period of time from the detection of the call, the voice is output. By outputting the message, the same effect as in the above-described embodiment can be obtained even for visitors who are not bothered.

[0021]

As is apparent from the above description, according to the television door phone apparatus of the present invention, the entrance slave unit operated by the visitor is operated by the resident in the dwelling unit using the indoor master unit. By providing the refusal button, if an unwanted and unwanted call is repeated, the call can be stopped by sending a message according to the degree of inconvenience of the resident from the entrance slave unit.
