Claims

[Claims for Utility Model Registration] A pinch roller that is pressed against a capstan that drives the tape; a pinch roller arm that rotatably supports the pinch roller at one end and rotatably supports the other end; A rotating arm provided to be able to rotate independently of the roller arm, a spring member stretched between the pinch roller arm and the rotating arm, and a cam portion that abuts the rotating arm. a cam member which applies a spring force of the spring member to the pinch roller arm by displacing the rotating arm, and presses the pinch roller to the capstan;
