Abstract

PURPOSE:To reduce power consumption by intermittently supplying electric power to a waiting circuit in waiting status. CONSTITUTION:Square wave pulse signals are continuously applied from a monostable oscillating circuit 6 to a switching circuit 7 to intermittently drive the circuit 7. The circuit 7 supplies electric power to a low power circuit which operates in reception waiting status and actuates the circuit 1 only when the circuit 7 is on. At the reception of radio waves, a detection signal is outputted from a signal detecting circuit 2. The detection signal turns on a switching circuit 4 to actuate an ordinary receiving circuit. At the same time the operation of the monostable oscillating circuit 6 is stopped.
