  The common door station 10 starts the operation in the initial setting mode or the normal mode by operating the setting switch 12. Hereinafter, the basic operation in each mode will be described.

  In the initial setting mode, a dwelling unit number is registered for each terminal T by an interactive operation using the small liquid crystal panel 20 and the numeric keypad 11a. At this time, an operation guide is appropriately displayed on the small liquid crystal panel 20, but it is better to output a guide voice from a speaker.

  The specific procedure for registering the dwelling unit number is not particularly limited. In short, for each terminal T, the dwelling unit number of the dwelling unit where the dwelling unit base unit 30 connected to the terminal T is installed can be freely registered and changed. For example, the terminal numbers to be operated may be displayed in order on the small liquid crystal panel 20 to prompt the input of the dwelling unit number for the terminal numbers. The dwelling unit number can be input with the numeric keypad 11a, and the input dwelling unit number is stored in the dwelling unit number storage unit 18 in association with the terminal number. Since the allocation rule of the dwelling unit number is not particularly limited, it is preferable to make it suitable for the situation of the apartment house such as the dwelling unit arrangement. For example, the dwelling unit number of the first floor room No. 2 may be “201”, “021”, or “21”. For a terminal T (not connected) that is not used, a specific value (for example, 999) indicating that the terminal is not used may be registered.

  Further, as initialization of the dwelling unit number, it is preferable that the dwelling unit numbers stored in the dwelling unit number storage unit 18 can be collectively erased by a predetermined key operation. The key operation for that purpose is not particularly limited, and for example, “****” may be operated with the numeric keypad 11a. If the collective erasure of such dwelling unit numbers is possible, there is no possibility that some old dwelling unit numbers may remain and cause problems when renewing the apartment house and reassigning the dwelling unit numbers to each dwelling unit.

  3A and 3B are examples of the dwelling unit numbers stored in the dwelling unit number storage unit 18 before and after the renewal of the apartment house. Here, it is assumed that the apartment building is 3 stories high, the management room and 2 dwelling units are located on the 1st floor, and 2 dwelling units are arranged on the 3rd floor. The number of terminals T,... T of the common entrance handset 10 is assumed to be 8.

  Before the renewal of the housing complex, the dwelling unit number “000” is registered in the first terminal T in the dwelling unit number storage unit 18 as a management room (shared unit) as shown in FIG. . Similarly, room numbers “101” to “302” are registered in the second to seventh terminals T from the first floor, the first room to the third floor, the second room, respectively. The eighth terminal T is not connected, and a value “999” indicating an unused state is registered.

  In the renewal of an apartment house, it is assumed that the previous management room was divided into a new management room and a dwelling unit. In other words, after the renewal, there will be a management room and three dwelling units on the first floor. The second and third floors are not changed. At this time, the dwelling unit base unit 30 in the management room is used as it is, and one dwelling unit base unit 30 is added for a new dwelling unit. In this case, the first to seventh terminals T,... T need not be shifted and adjusted, and the newly added dwelling unit 30 is vacant in the common entrance unit 10. It may be connected to the eighth terminal T. Then, the dwelling unit number “103” may be registered for the eighth terminal T in the initial setting mode.

  FIG. 3B shows the registration state of the dwelling unit number for each of the terminals T after such an initial setting mode is executed. As shown in the figure, the dwelling unit numbers for the first to seventh terminals T,... T remain in the state shown in FIG. 3A, and only the dwelling unit number for the eighth terminal T is changed to “103”. ing. Since the dwelling unit number “103” is a serial number from the existing dwelling unit numbers “101” and “102”, it does not cause a sense of incongruity.

  The normal mode is a mode in which a call call similar to the conventional one is performed between the common entrance handset 10 and the dwelling unit base 30.

  Specifically, the call operation is started by a call operation in which the dwelling unit number is designated in the common entrance handset 10, that is, the input of the dwelling unit number using the numeric keypad 11a and the subsequent operation of the calling key 11b. That is, when detecting the calling operation, the control unit 17 controls the circuit selection circuit 15 to form a transmission path with the dwelling unit parent unit 30 connected to the terminal T corresponding to the designated dwelling unit number. When the transmission path is formed, the dwelling unit 30 starts ringing and starts supplying power to the camera unit 16 of the common entrance station 10 through the transmission path. As a result, the visitor video is displayed on the monitor screen of the dwelling unit 30. When a response operation is performed at the dwelling unit parent machine 30, ringing of the ringing tone is stopped and a call with the visitor becomes possible.

  Thereafter, when the unlocking operation is performed at the dwelling unit master unit 30, an unlocking signal is transmitted from the dwelling unit base unit 30, and when the control unit 17 of the common entrance unit 10 detects the unlocking signal, the electric lock control device 40 is detected. To unlock the common entrance door.

  In the present invention, since it is configured as described above, the room number can be registered and changed at any time for any terminal T by executing the initial setting mode in the common entrance handset 10. That is, the correspondence between the terminals T,... T and the room numbers is not fixed in hardware, and can be freely changed. Therefore, when renewing a housing complex, by utilizing existing wiring and registration of the dwelling unit number, only the minimum wiring adjustment and the registration change of the dwelling unit number are required, and the dwelling unit number that matches the dwelling unit arrangement in the housing complex. Registration, and the labor of the work is greatly reduced.
