Claims

[Scope of utility model registration request]

A drive gear rotated together with the capstan by a motor, a switching gear rotated by the drive gear, a head drive cam that rotates together with the switch gear, a head berth driven by the head drive cam, and A tape that is provided with a magnetic head mounted on a head base and a locking member that locks a switching gear when the magnetic head is moved to a position where it contacts the tape and when it is moved to a position where it separates from the tape. In the player mode switching device, when the player is started, the drive gear is rotated for a certain period of time by a motor, and the switching gear is returned to a position where the magnetic head is separated from the tape, and at the same time as the motor is started, the switching gear is installed on the head base. 1. A mode switching device for a tape player, comprising: a control member for supplying current to an erase head that has been erased.
