Abstract: PURPOSE:To unnecessiate a switch operation when the call from a door phone is switched by performing the inversion control to a call impossible state for a coll line when the non-detection state of a call signal is continued for a prescribed time. CONSTITUTION:When a call response switch is pressed and operated in an interphone, a call is started and the 'H' level of a control signal D4 is outputted. As a result, an inversion control to an ON state is performed for a hand free call control part 23 and the part is connected with the call line between a door phone terminal 11, a microphone MC and a speaker SP. A call signal detection part 22 detects the call voice inputted from the door phone and the call voice detected by the microphone MC and performes an 'H' level output as a signal S4. At this point, the timer circuit of a control circuit 30 is reset by the fall of the signal S4, and when a non-detection state is continued in the detection part 22 for prescribed time, the circuit 30 drops the signal D4 to an 'L' level. Thus, the inversion control to an OFF state is performed for a line control means SW0 and the call switching of a door phone 6 can be performed without performing a switch operation.
