Claims

[Scope of utility model registration request]

a capstan for causing a magnetic tape to travel; a pinch roller for pressing the magnetic tape against the capstan; a first rotating arm supported by a first support shaft and supporting the pinch roller at one end; a second rotating arm that is pivotally supported, one end of which is biased to rotate by a spring, and whose position is regulated by a stopper; a connecting pin in the intermediate portion; both ends connected to the other end of the first rotating arm; a link arm that is coupled to the other end of the second rotating arm, a slide lever that is slid by a manual drive; , a third rotating arm having an elongated hole consisting of a first guide hole and a second guide hole into which the connecting pin loosely fits, the amount of movement of the connecting pin relative to the amount of rotation of the third rotating arm; compared to when guided through the first guide hole,
A pinch roller crimping mechanism characterized in that the elongated hole is formed so that the elongated hole is smaller when guided into the second guide hole.
