Although the configuration and connection of the room master unit 10a have been described above, the description of the other room master units will be omitted because each of the other room master units has the same configuration and connection. The intercom apparatus for housing a housing according to the present invention having the above-described configuration is, for example, the master unit 10 for the room.
When the resident of a goes out, the recording unit 2 of the master unit 10a in the room
The go-out set button (not shown) provided on the operation unit 24 is pressed to set the absence mode. When the room master unit 10a is set to the absence mode, the signal output circuit from the recording control device CPU2
26, an answering mode signal is input to the recording control device CPU 17 via the signal input circuit 176 of the recording unit 107, and the recording unit 107 is set to the absence mode.

When a visitor comes while the room master unit 10a is set to the absence mode, if the room number corresponding to the room master unit 10a is pressed on the operation unit 75 of the collective entrance machine 7, the room master unit 10a is pressed. A call signal for calling is sent to the control unit CPU7.
The control unit CPU7 transmits a call signal to the room master unit 10a via the communication circuit 71, the communication / voice switching circuit 51 of the controller 5, the trunk lines R1 and R2, and the communication / voice switching circuit 51 and the video controller. The control circuit CPU6 is controlled via the communication / video switching circuit 62 of 6.

In the room master unit 10a, the communication circuit 11 of the room unit 1,
A call signal is transmitted to the recording control device CPU2 via the control device CPU1, the output control circuit 14, and the signal input circuit 22 of the recording unit 2. Since the master unit 10a in the room is set to the absence mode, the recording control device CPU2 operates the video circuit 21 of the recording unit 2.
And the video memory 23 are operated, and the signal output circuit 2
6. The recording control device CPU 17 operates the communication circuit 171 and the audio circuit 172 through the signal input circuit 176 of the recording unit 107.

The control unit CPU7 of the collective entrance machine 7 operates the camera 72 and transmits the video signal f ₂ from the camera 72 to the control circuit CPU6 via the video circuit 73 and the video circuit 61 of the video controller 6,
The control circuit CPU6 sends it to the room master unit 10a via the communication / video switching circuit 62 and the video signal trunk lines A1 and A2. Living room base unit 10a
Then, the video signal f ₂ from the video controller 6 is fed to the video branching / distributing device 4,
It is input to the video memory 23 via the video circuit 21 of the recording unit 2, and the A / D conversion circuit 23b converts the analog video signal f ₂ into a digital signal, and the recording memory controller CP
It is recorded in the video memory area Ma ₁ of the recording address Aa ₁ by U23.

At the same time that the video signal f ₂ is recorded in the recording unit 2, the audio circuit 172 operated by the recording control device CPU 17 of the recording unit 107 indicates that the room master unit 10a is absent and that the visited message has been visited. The communication circuit 171, the trunk lines R1 and R2, and the communication / voice switching circuit of the controller 5 are used to convey the voice signal to the visitors at the entrance by voice
It is transmitted to the collective entrance machine 7 via 51, and is output by the voice circuit 74 of the collective entrance machine 7.

As a result, the voice signal f ₁ which is the message of the visitor recorded by the microphone 74a of the collective entrance 7 is the communication circuit 71, the communication / voice switching circuit 51 of the controller 5, the trunk lines R1, R2,
It is transmitted to the A / D conversion circuit 175 via the communication circuit 171 and the audio circuit 172 of the recording unit 107. In the A / D conversion circuit 175, the voice signal f ₁ which is an analog signal is converted into a digital signal and recorded in the voice memory Mb ₁ of the recording address Ab ₁ .
At this time, the audio signal f ₁ converted into a digital signal is recorded by the recording control device CPU 2 of the recording unit 2 so as to correspond to the recording address Aa ₁ of the video signal f ₂ recorded in the image memory 23 of the recording unit 2. Recording controller CPU17 of unit 107
Control. Recording controller recording controller CPU17 controlled by CPU2, the record audio signals f ₁ which is converted into a digital signal to the voice memory area Mb ₁ recording address Ab ₁ corresponding to the recording address Aa _1.

[0032] In still image to the image memory area Ma ₁ recording address Aa ₁ video memory 23 is recorded, are again recorded if another visitor's image is sent to the picture memory area Ma _2, by sequentially calling It is recorded in the image memory area Ma ₁ to Ma ₄ corresponding to each recording address Aa ₁ ~Aa ₄ by delivery of the video. Video memory area for recording all visitors Ma _{1 to} Ma ₄
When a video is recorded in, the video memory area where the oldest video is recorded is sequentially overwritten.
Audio memory area Mb _{1 to} Mb ₄ also has video memory area
Since it corresponds to Ma _{1 to} Ma ₄ , in the same way, when audio is recorded in all audio memory areas Mb _{1 to} Mb ₄ , overwrite recording is performed sequentially from the audio memory area in which the oldest audio is recorded. To be done.

Regarding the reproduction of the video and audio recorded in the room master unit 10a, the out-going set button of the operation unit 24 of the recording unit 2 is pressed to release the absence mode, and the reproduction button ( pressing the not shown), the signal output circuit 26 from the control unit CPU 2, the signal input circuit 176, the reproduction signal f ₃ indicating the image memory area Ma ₁ to Ma ₄ is input to the recording control unit CPU 17. Further, the control unit CPU2 recording unit 2, an output control circuit 25, reproduction controller CPU3 through the signal input circuit 33 of the video monitor 3 signals f ₃ is delivered.

Further, the control device CPU2 of the recording unit 2 is
Memory control circuit 23c of video memory 23, memory control device CPU
Controls 23, if only the image memory area Ma ₁ of video memory area image is recorded e.g. recording address Aa _1, an image was recorded in the image memory area Ma ₁ D / A
The conversion circuit 23a converts the digital signal into an analog signal and reproduces it on the monitor 32 of the video monitor 3. When playing back this video and playing back the audio, the control unit CPU2 controls the recording control unit CPU17 of the recording unit 107 to set the recording address.
The voice recorded at the recording address Ab ₁ corresponding to Aa ₁ is converted from a digital signal to an analog signal by the D / A conversion circuit 175 and reproduced by the speaker 173 via the voice circuit 172.

[0035]

As is apparent from the above description, according to the intercom apparatus for housing complex of the present invention, not only the image of the visitor is recorded when the user is away, but the voice is recorded corresponding to the image.
