Claims

[Scope of utility model registration request]

A switching gear that rotates when switching modes; a head base drive cam that is provided on the switching gear and contacts the head base to drive the head base to each mode position; a play arm having lock protrusions for stopping the play arm, and a lock pin abutting on each of the lock protrusions, the lock pin being rotatable in a direction toward and away from the lock protrusions; a solenoid having a plunger connected to a play arm, and the lock pin is released from the lock protrusion or locked to the lock protrusion when the solenoid is excited and the plunger is attracted. A mode switching device for a tape player, characterized in that the switching gear is provided with a stopper against which the locking pin hits in the middle of a stroke in which the plunger is attracted to the maximum extent when the solenoid is energized. .
