Claims

[Claims for Utility Model Registration] A movable board for setting and canceling a play mode that is movably arranged so that a stop position and a play position can be selectively taken; a biasing device that applies a biasing force of; a movable plate guide portion that guides the movable plate; a pinch roller arm that is rotatably supported on a support shaft provided on the movable plate; a freely supported pinch roller; a stopper pin provided on the movable plate so as to limit the rotation of the pinch roller arm in the direction of the capstan at a certain position; an engaging end that is provided on the movable plate so as to be guided and slide in a direction substantially perpendicular to the moving direction of the movable plate, and that stably engages with a locking portion described below at the stop position; a locking portion that engages with the locking end portion of the locking plate to lock the locking plate in the stop position; and a locking portion that locks the locking plate in the stop position; (1) provided between the engagement plate and the pinch roller arm so as to have a spring force to pull the engagement plate in the direction of the locking portion and bias the pinch roller arm in the direction of the capstan; moving the movable plate from the stop position to the play position against the engagement between the engagement plate and the locking portion by the coil spring, and moving the movable plate in the play position to the stop position. A play mode setting/cancellation mechanism consisting of an operation unit that moves to a certain position, and a play mode setting/cancellation mechanism.
