A first one-shot circuit which takes the output as an input and sets the notification sound ringing time of the notification sound circuit by its output signal, and a second one-shot circuit which takes the output of the detection circuit as an input and controls the receiving circuit power supply to be turned off for a predetermined waiting time. 1. A wireless interphone comprising: a circuit for activating a notification sound circuit when the detection circuit output occurs, and turning off the power supply of the receiving circuit except for the notification sound circuit for a predetermined period of time.

Claims

[Scope of utility model registration request]

In a wireless intercom that performs intermittent reception by repeatedly turning on and off the transmitter circuit power supply in synchronization with the oscillation circuit output signal in a standby state, an annunciation sound circuit is provided with the output of the detection circuit that detects a call signal from the other party as input. a first one-shot circuit that sets the alarm sounding time by the output signal thereof; and a second one-shot circuit that receives the output of the detection circuit as an input and controls the receiving circuit power supply to be turned off for a predetermined period of time; This wireless intercom is configured to operate a notification sound circuit when a circuit output occurs and turn off the receiving circuit power supply except for the notification sound circuit for a predetermined period of time.
