コーダーの操作回路。Power is supplied to the motor etc. through a trigger switch that is turned on during each trigger operation such as playback, fast forwarding, rewinding, etc., and the tape drive mechanism is set at a predetermined operating position by the rotational driving force of the motor. After the trigger switch is turned off, the tape recorder turns the trigger switch off again, and power is not supplied when the trigger switch is turned off and power is not supplied, but power is supplied only when the trigger switch is turned on and the trigger is operated. a switching transistor that becomes conductive when the switching transistor is conductive, a first muting transistor that becomes conductive when the switching transistor is conductive and bypasses the audio signal on the signal line, and a first muting transistor that becomes conductive when the switching transistor is conductive and generates bias oscillation. a control circuit comprising a second muting transistor for cutting off power supply to the circuit;
When the trigger switch is in an OFF state, the trigger switch is set to a completely inactive state in which no current is consumed by each transistor;
During a trigger operation in which the trigger switch is in an ON state, the first and second mutating transistors are operated until the tape drive mechanism section is set to a predetermined operating position, that is, the trigger switch is set in an open operating state in an ON state. An operating circuit for a tape recorder characterized by performing control operations according to the following.
