BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a videophone apparatus with an answering machine function, and more particularly to a videophone apparatus with an answering machine function provided with a visitor detection sensor for outputting a visitor detection signal in a front door unit with a camera.

[0002]

2. Description of the Related Art Conventionally, a videophone apparatus with an answering machine function has a camera-entry terminal with a camera eye 31, a speaker 32a, a microphone 32b, and a call button 33, as shown in FIG. EQ ₁₁ , handset 36
TV monitor EQ ₁₄ having a indoor apparatus EQ _12, CRT 35 having a, and a video signal recording apparatus EQ ₁₃ having a setting button 37.

[0003] camera with the entrance door station EQ ₁₁ is outdoors, the indoor apparatus EQ _12, the video signal recording apparatus EQ _13, television monitor EQ ₁₄ is installed in a room. In addition, door phone master unit EQ ₁₂
The television monitor EQ ₁₄ and the video signal recording device EQ ₁₃ are provided in the same housing as necessary, and the handset 36, the CRT
35, members such as a setting button 37 are front-mounted on this housing. Further, in addition to it is another call when separately added indoor apparatus is provided with the indoor apparatus EQ _12, to connect the central office line provided with outside call operation member such as a numeric keypad to the indoor apparatus EQ ₁₂ intercom In some cases, it is a telephone with a base unit function.

[0004] The outdoor side entrance door station with camera EQ ₁₁ and the indoor apparatus EQ _12, television monitor EQ _14, the cable compartment side of video signal recording apparatus EQ ₁₃ is suitable for transmission and reception of video signals such as 2-wire balanced cable It is connected by the CBL _2. In voice mail TV telephone device of this configuration, when the setting button 37 of the interior side of the video signal recording apparatus EQ ₁₃ is operated is set to the Voice mode, the effective range of the camera eye 31 of the camera with the entrance door station EQ ₁₁ When a visitor located inside operates the call button 33, the video signal recording device EQ ₁₃ records the video signal captured by the camera eye 31 as one still image.

A plurality of still images are recorded on the video signal recording device EQ ₁₃ in accordance with the number of operations of Step 3.

[0005] The video signal recording apparatus EQ ₁₃ is constituted by a semiconductor memory circuit which is typically an IC, since there is only the capacity for recording still images 10-15 sheets, when the video signal of the same visitor recording plural other However, there is a problem that the number of video signals recorded by the visitors is reduced. Also, in a system in which the guidance message is not transmitted from the speaker 32a, the same visitor often operates the call button 33 several times,
There is a drawback that the recording capacity cannot be used effectively.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and provides a call button and a visitor detection sensor in a camera-equipped entrance terminal, and monitors the operation and recovery state of the visitor detection sensor. Accordingly, an object of the present invention is to provide a videophone apparatus with an answering machine function that can effectively use a recording capacity without recording a plurality of still images even when the same visitor operates the call button a plurality of times.

[0007]

SUMMARY OF THE INVENTION In order to achieve this object, a telephone communication device with an answering machine function according to the present invention is provided with a camera-equipped entrance device that images a visitor and generates a video signal. A call button provided to output a call signal, a visitor detection sensor that detects a visitor, outputs a visitor detection signal, and recovers when the visitor leaves, and an indoor side connected to a camera-equipped entrance device. A video signal recording device connected to the parent device and a video signal recording device that is connected to the indoor side parent device and records a video signal as one still image when a call signal and a visitor detection signal are received after the visitor detection sensor is restored. It is a thing.

[0008]

In the videophone with answering machine function, when a visitor stands in the effective range of the camera eye of the camera-equipped front door and presses the call button, a video signal recording device is provided by a visitor detection sensor and AND logic of the call button. The sensor monitoring program built in the recording CPU is executed. By executing the sensor monitoring program, one still image is recorded in the still image memory. Even if the visitor presses the call button again, the visitor detection sensor does not recover and the sensor monitoring program does not confirm that the visitor has left, so the second still image is not recorded.
