Claims

[Scope of utility model registration request]

The head base includes a magnetic head mounted thereon and is slidably provided on the chassis, a switching cam that comes into contact with the head base and moves the head base forward and backward relative to the tape, and a switching gear that rotates together with the switching cam. In the switching device for a tape player, the switching gear is formed with a stopper step that is locked by a locking member when the head base reaches a predetermined switching position;
This lock member is biased by a spring in the direction of locking the stopper step, and is connected to a solenoid mechanism that drives the lock member in a direction away from the stopper step. A switching device for a tape player, characterized in that a guide is formed near the switching gear for forcibly directing the locking member in the direction of the stopper step when the switching gear rotates.
