6, the telephone 15 is off-hook based on the signal from the call detection section 17, and an absence signal is output.

Next, the operation of the entrance management system according to the present invention will be explained. First, when leaving the residence, operate the ``Absence'' button etc. on the ``Absence'' switch section 16 of the dwelling unit C,
Switch to . Now, the visitor operates the number key etc. of the door phone 2 in the entrance area A, and inputs an identification code such as a residence number in order to call the place to visit. This identification code is PBX9
Based on this, the PBX 9 exchanges and connects the telephone line with the door phone 2 to the telephone 15 of the dwelling unit C. At this time, the identification code from the door phone 2 is input from the PBX 9 to the storage unit 10 via the control unit 13, and is stored in, for example, the RAM (
(writable/rewritable memory). telephone 1
5 rings in response to a ringing signal from the PBX 9, but when the answering switching section 16 switches to "absent", the calling detecting section 17 counts the ringing signals via the control section 18, and for example, 3 rings.
A signal is output by counting the number of times. This signal causes the control unit 1 to
8, and then sends out an absent signal. This absence signal is inputted to the determining section 11 of the management section B via the PBX 9, and the absence is determined. Based on this determination, first, a voice message of "Away" is read from the message storage unit 12 to inform the visitor at the entrance that the person to be visited is not home, and is transmitted to the doorbell 2 via the PBX 9 and output as voice. . Thereafter, the output of the switching section 4 is switched to the recording/reproducing section 3 side via the control section 13, and the recording/reproducing section 3 is driven to the recording state. Then, the video signal from the camera 1 and the audio signal input from the door phone 2 via the PBX 9 and the control unit 13 are recorded for a required time, for example, 2 minutes. In the above, the telephone 15 outputs an absence signal to the PBX 9, but it may also issue a transfer command to a specific line (an answering machine dedicated line). P.B.
The X9 can be configured to be connected to a dedicated answering line in response to a transfer command, and to respond to the message and control the recording/reproducing section 3 via this dedicated line.

[0010] When reproducing the recording made while the resident of dwelling unit C was away, first, the telephone 15 is off-hook, and then a preset signal, for example, "#" and the number of the identification code are dialed. input. This “#” signal is discriminated by the discrimination unit 11 via the control unit 13, and based on this discrimination, the data stored in the memory unit 10 is read via the control unit 13, and is identified by the PBX 9 when the telephone 15 goes off-hook. A match with the identification code of the telephone 15 is determined. Based on this determination, the recording/reproducing unit 3 is driven via the control unit 13 to search for the identification code and reproduce the image and audio recorded following the identification code. The reproduced signal is R
The signal is inputted to the F modulation section 3, modulated as appropriate into a high frequency signal of an empty channel such as television broadcasting, and transmitted to the receiver 14 of the dwelling unit C via the mixing section 6 and the distributor 8. This allows you to listen to messages from visitors while you are away while viewing the images. Alternatively, if the PBX 9 has a function of identifying the identification code (telephone number, etc.) of the telephone when the telephone is off-hook, inputting the identification code using the telephone can be omitted. In addition, if the PBX 9 and the telephone 15 of the dwelling unit have a transfer function, the “#”
'' to connect to a dedicated answering line, search for the identification code, and play images and audio. Note that the identification code recorded in the storage section 10 by the operation of the door phone 2 may be automatically erased by a reproduction command signal of the recording/reproducing section 3 issued by the control section 13 or the like.

[0011]Furthermore, if the answering switch 16 is not switched to "absent", the PBX 9 exchanges and connects the telephone line to the telephone 15 of the desired dwelling unit C by a calling operation of the door phone 2. As a result, a ring tone is output from the telephone 15,
If you go off-hook, you can talk to the doorbell 2. Since the output of the switching section 4 is switched to the RF modulation section 5 side, the signal of the image of the visitor etc. from the camera 1 is transferred to the switching section 4.
The signal is inputted to the RF modulation unit 5 via the RF modulator 5, where it is appropriately converted into a high frequency signal of an empty channel such as a television broadcast, and inputted via the distributor 8 to the receiver 14 of the dwelling unit C, where the image of the visitor is projected on the screen. do. In this case, the voice from the doorbell 2 is heard on the telephone 15. In addition, the identification code such as the housing unit number inputted through the doorbell 2 is temporarily stored in the storage unit 10;
Since the absence signal is not sent from the residential unit C, the required time is
For example, it is automatically deleted after 3 minutes.

[Effects of the Invention] As explained above, according to the entrance management system according to the present invention, if the telephone of the dwelling unit is set to ``away'', when a call is made from the doorbell at the entrance, the management department will An image of the entrance taken by the camera and the sound from the doorbell are recorded on the installed recording and reproducing unit following the identification code of the dwelling unit. This recording is played back by operating the telephone in the residence, and is output as images and audio from the receiver. In this way, you can listen to the message while watching the visitor's situation on the receiver screen while you are away, and if the visitor is an important visitor, you can respond later in an appropriate manner and avoid politeness. It is possible to prevent failures such as doing so. Since images and sounds are recorded on a recording and reproducing device that is shared by multiple dwelling units, for example, households that do not have many visitors have the advantage of being able to enjoy convenience with relatively little burden. It is.
