Claims

[Scope of utility model registration request]

A pinch lever equipped with a pinch roller and an auxiliary lever are rotatably supported on a support shaft on a fixed board, and a first spring is interposed between these levers to temporarily fix them together. 1 and 2nd pinch roller devices, a head substrate on which a magnetic head is mounted and movable in the front-back direction, first and second control members movably provided to be movable in the left and right directions of the head substrate, and the first and second pinch roller devices. (or second) control member to the first
When the second (or first) control member is opposed to the contact portion of the auxiliary lever of the (or second) pinch roller device, the second (or first) control member is
or (1) a reversal switching lever that moves so as not to face the contact portion of the auxiliary lever of the pinch roller device, and the first and second pinch roller devices are moved to the first position when the head substrate is retreated; Spring, the second force weaker than the force of Ng.
The first (or second) capstan is separated from the first and second capstan by a spring, and when the head board moves forward, the first (or second)
The control member rotates the first (or second) pinch roller device in the direction toward the capstan against the second spring, and after the pinch roller contacts the capstan, only the auxiliary lever is rotated against the first spring. 1. A pinch roller actuating device for a reciprocating magnetic recording and reproducing device, characterized in that the pinch roller actuating device is configured to rotate and generate a pressing force of the pinch roller.
