According to the state in which the terminal unit and the main body are attached to the double-walled member having the inner wall and the outer wall, the exposed type (see FIG.
The one of (a)) and the one of embedded type (FIG. 6 (b)) are known.

The exposed intercom apparatus shown in FIG. 6 (a) is designed such that the terminal unit and the main body are attached to the wall located outside the wall member, that is, on the room side so as to project. On the other hand, in the embedded intercom device shown in FIG. 6 (b), the terminal unit is located between the inner wall and the outer wall (that is, it appears to be embedded from the outside), and only the main body is outside the wall member. It is designed so that it can be attached by protruding.

In both the exposed type and the embedded type intercom system, a signal line passing through between walls and an AC cord for power supply are provided on one end of the wall-mounting metal fitting facing the intercom body side. It is configured to connect to the connected connection terminal. Then, a signal line and an AC cord for power supply are further drawn out from the connection terminal and connected to the main body of the intercom apparatus. Therefore, when the wall-hanging metal fitting and the main body are combined and assembled, a plurality of connection terminals, a signal line to be input to the wall-hanging metal fitting and an AC cord for power supply, a signal line to be connected to the main body of the intercom device from the wall-hanging metal fitting, and The AC cord for the power supply was housed in the narrow space between the back surface of the main body and the surface of the wall hangings.

[0005]
