Abstract

PURPOSE:To obtain an extremely stable, excellent power souce circuit by providing a backup circuit for a power voltage and an initializing circuit. CONSTITUTION:When a power source E is turned off in stationary operation state and the voltage from it disappears, a discharge voltage from a large-capacity capacitor C0 charged during the stationary operation state is supplied continuously to put a backup circuit 11 in operation. Namely, a transistor (TR)Q1 turns on and backup power voltage is applied continuously from the moveable contact of a power switch S2 with a prescribed time constant determined by a capacitor C1 and a resistance R1. Consequently, a tape recorder mechanism and its circuits are stopped in normal stopping states. Thus, an extremely stable, excellent power source circuit of an electrocontrol type tape recorder is obtained.
