Abstract

PURPOSE:To reduce the power consumption of a battery, and to improve the use convenience, by providing a call detecting circuit, and a circuit for cutting off the electric power from a battery power source after a prescribed time, after a call operated by an output of said circuit has been finished, on a slave station operated by the battery power source. CONSTITUTION:A slave device of a wireless communication equipment is driven by a battery power source 30, and when a calling push button 31 is pushed, contacts 32-33 are closed, and the electric power is supplied to each circuit of the slave device from a line 46 through a transistor TR1 of an FF55. When a contact 34 conducts, 1kHz is generated from an oscillating circuit 54, and by this signal, a carrier wave of an oscillator 26 is modulated 27, and a master device is called. When the push button 31 is released, a capacitor C44 of a monostable circuit 35 starts to be charged, and when a call starts, a call detecting circuit 38 detects a sound signal which is transmitted and received, conducts TRs 7, 8 and, discharges the charge of the C44. When a call is finished, the circuit 35 sends a reset signal to the FF55 after a prescribed time has elaspsed, cuts off the TR1, and disconnects the electric power from the electric power source 30. When voltage of the electric power source 30 drops, a battery power source output level detecting circuit 37 detects it, and it is informed to the master device by an output of an oscillator 53.
