Claims

[Scope of utility model registration request]

A head board is slidably arranged on a mechanism board, a winding portion of a torsion spring is attached to a shaft provided on the head board, and both ends of the spring are locked to stoppers provided on the head board. At the same time, a pinch roller arm to which a pinch roller is rotatably attached is rotatably supported on the mechanism board, the pinch roller arm is brought into contact with one end of the torsion spring, and the head board can be advanced toward the other end. set the length from the winding part of the torsion spring to the pinch roller arm contact position to be longer than the length to the operation member contact position, and also set the length from the rotational fulcrum of the pinch roller arm to the pinch roller The length to the spring abutting portion is set longer than the length to the end of the operating member. The tape recorder is configured such that the head board moves forward and both ends of the torsion spring separate from the stopper at the performance position where the pinch roller is in contact with the capstan.
