Abstract

PURPOSE:To reduce the power consumption in the normal period excluding the period around the voltage transition period, by giving a compensating countermeasure such as a stoppage of oscillation or the like for an increment of internal resistance during the voltage transistor period of an AgO battery having the voltage varying in steps. CONSTITUTION:The voltage of the battery 16 is detected 21. Then the electric power is supplied to the oscillating circuit 1 through a voltage reducing circuit 18 having a large voltage reducing ratio in case the battery 16 is at the side of a high potential; and the electric power is supplied to the circuit 1 through a voltage reducing circuit 19 having a small voltage reducing ratio after the battery is shifted to the side of a low potential. When the voltage of the battery 16 starts to shift to a low level of voltage, the signal is delivered from the timer 26 during the voltage transistion period to actuate the control functions 1a, 3a and 7a provided at the circuit 1, the motor waveform shaping circuit 3 and the alarm tone waveform shaping circuit 7, respectively.
