Abstract
An actuating device for a pinch roller in a tape recording and/or playing device has a capstan spindle driven by a mechanism supported on a chassis. A pinch lever supports the pinch roller. At least one drive lever is rotatably coupled to the pinch lever and mounted to pivot about a fixed axis normal to the chassis for swiveling the pinch roller between resting and working positions. A spring connects the pinch lever and the at least one drive lever for urging the pinch roller against the capstan spindle only in the working position. A first guide controls the swiveling of the at least one drive lever. A lift roller is rotatably supported by the pinch lever and disposed in proximity to the pinch roller. The lift roller has a cylindrical region and a conical region having a diameter which increases in a direction away from the chassis. A second guide controls engagement of the pinch roller and the capstan spindle in response to the swiveling and in the working position by imparting a motion to the pinch lever in the direction away from the chassis during the swiveling. In an embodiment having two drive levers, the first and second drive levers and the spring form an inherently rigid lever system when the pinch roller is not in the working position.
