[Claims for Utility Model Registration] Includes a full-wave rectifier circuit that rectifies AC power and a capacitor that is charged by the output of this full-wave rectifier circuit. A power supply muting circuit comprising a time constant circuit and a switching transistor circuit connected to the output side of the time constant circuit, the power supply muting circuit using the output of the switching transistor circuit as a muting control signal, the time constant circuit In contrast, when the power switch is on, the time constant circuit constitutes a charging circuit in conjunction with the power switch, and when the power switch is off, the capacitor is short-circuited in order to quickly discharge the capacitor in the charging device. A power supply muting circuit characterized in that a switch is connected to the power supply muting circuit.
