Claims

[Claim for Utility Model Registration] When the motor rotates in the forward direction, it meshes with the reel shaft on the take-up side, and when it rotates in the reverse direction, it meshes with the reel shaft on the supply side, and the driving force of the motor is transferred to the reel shaft on the take-up side. an idler gear that transmits transmission to the shaft or supply reel shaft; and an idler gear that operates when the motor rotates in the opposite direction, and a head base equipped with a magnetic head and a pinch roller is moved backward by the driving force of the motor, and the magnetic head and pinch roller are moved back. a cam gear that is operated by this cam gear, and when the rotation direction of the motor changes from the forward direction to the reverse direction, the idler gear meshes with the supply side reel shaft after the pinch roller separates from the tape; A play/rewind switching mechanism in a cassette player, comprising: a lever for regulating the movement of the rewind so that the rewind is played;
