モード切換装置。 A drive gear rotated by a motor, and a plurality of toothed portions that are meshed with the drive gear and rotated to set the mechanism to a plurality of operation modes and to maintain rotational positions corresponding to the respective operation modes. Controlled by a formed cam disc and an electromagnet,
a trigger lever arranged so as to be able to take a lock position in which the cam disc is locked at a rotational position corresponding to each of the operation modes and a lock release position in which the cam disc is released from the lock and brought into engagement with the drive gear; a control circuit that controls the electromagnet to operate the trigger lever and control the rotation of the cam disk to a rotational position corresponding to each operation mode; and a control circuit that detects the operating state of the electromagnet and the movement position of the trigger lever; and a malfunction prevention circuit that outputs a stop control signal to the control circuit when the trigger lever moves to the unlocked position with the electromagnet in the de-energized state, and the trigger lever moves to the unlocked position with the electromagnet in the de-energized state. When the cam disk moves, the malfunction prevention circuit supplies a stop control signal to the control circuit to forcibly enter the stop mode, so that the rotational position of the cam disc and the operating state of the control circuit are different. A mode switching device for a tape recorder, characterized in that the mode switching device prevents.
