Abstract

PURPOSE:To enable to perform stable circuit operation even with the cell voltage lowered, by keeping the oscillation operation of the oscillated source fed from the main power normally, independent of the closing condition of the power switch. CONSTITUTION:To the signal detection circuit 4 having the oscillation source 3 used for signal detection, independently of the closing condition of the power switch 7, power is fed from the main power 6 normally, allowng to keep the oscillation operation of the oscillation source 3. Further, when the power switch 7 is opened, control is made so that the output of the signal detection circuit 4 is kept constnat. Thus, even with the cell voltage lowered, stable operation can be performed.
