回路。 In a tape recorder configured such that the switching to at least a playback operating state is performed by the rotational force of an electric motor, the playback operating state is maintained by a lock mechanism, and the holding operation by the locking mechanism is released by the rotational force of the electric motor, An operation control circuit that receives a control signal when a stop operation switch, a regeneration operation switch, etc. is closed and outputs a switching signal corresponding to each operation, and a detection transistor that operates in reverse when the power supply voltage drops to a predetermined value. and a switching transistor which is caused to perform an inverted operation when the detection transistor performs an inverted operation due to a drop in the power supply voltage, and the inverted operation of the switching transistor causes the operation control circuit to input a control signal for stopping. A tape recorder lock prevention circuit is characterized by:
