ト回路。 A switching type power switch, a muting control transistor, and a reset control transistor are connected between the secondary winding of the power transformer and the rectifier circuit, and when the power switch is on the OFF terminal side, power is supplied from the OFF terminal side. When the bias line that operates the muting and reset control transistor and the power switch are switched to the on terminal side, power is supplied from the output side of the rectifier circuit, and the circuit remains on for a predetermined period determined by the time constant circuit, and the power switch is turned on. A muting and resetting circuit comprising a control circuit for operating said muting and resetting control transistor in an on state.
