Abstract
A pinch roller of a portable video tape recorder is urged against a capstan shaft by a rotatable arm rotated by an eccentric cam. The arm is provided with a pin spring biased against side surface of the eccentric cam. After a portion of side surface of the eccentric cam most remote from an axis of rotation of the cam has passed by the pin, the rotation of the eccentric cap is stopped thereby to prevent the pinch roller from disengaging the capstan shaft.
