Abstract
In an autostop mechanism in a tape recorder equipped with an urging member, a sliding member and a shut-off cam gear, the urging member is located on a bottom surface of a chassis and is formed by a wire spring member. The wire spring member has a proximal end portion shaped like a polygon slightly smaller than a diameter of a shaft of a take-up reel so as to provide urging force when fitted over the shaft of the take-up reel, a distal end extending toward the sliding member, and a midway portion bent at a predetermined angle to form a bent portion abutting against the sliding member in such a way that the urging force of the wire spring member and an action of the distal end of the wire spring member press the sliding member toward a center of the shut-off cam gear cam gear by regardless of the rotational direction of the take-up reel.
