ース式テーププレーヤのモード切換装置。 a drive gear that is rotationally driven by a motor; a switching gear that has teeth that mesh with the drive gear and has a missing tooth; and when the missing part faces the drive gear. A locking member that comes into contact with a stopper provided on the switching gear to lock the switching gear, a solenoid that drives this locking member in the unlocking direction, and a head driving cam provided on the switching gear that contacts the tape. a magnetic head that moves to a play mode position where it moves away from the tape and a stop mode position where it moves away from the tape; and a reverse switching cam provided on a switching gear that moves a pair of pinch rollers toward the capstan in accordance with the drive position. In a mode switching device for an auto-reverse tape player, which is provided with a reverse switching lever having regulating portions that alternately regulate, the magnetic head is in a stop mode position and the switching gear is locked by a locking member. The reverse switching lever is provided with a driving part that is pushed out to a position where the reverse switching cam is driven by the locking member when the lock is released by the solenoid from the state in which the reverse switching lever is in the reverse switching position.
The switching gear is also provided with a regulating cam that maintains the drive portion of the reverse switching lever in a position away from the locking member when the magnetic head is in the stop mode position and the switching gear is locked by the locking member. A mode switching device for an auto-reverse tape player characterized by the following.
