Retaining device for an eject lever of a disk recording and reproducing

Abstract

Herein disclosed is a retaining device for retaining a generally flat elongated part of a magnetic disc recording and reproducing apparatus. The lever retaining device is used to retain a disc eject lever in position on a bearing member of a disc player while preventing the same from slipping out of the position. Two guide pins are anchored upright on the bearing member of the disc player at a predetermined spacing from each other and have circumferential grooves near the heads thereof. Two slots are formed in the disc eject lever for allowing the two guide pins to extend therethrough when the eject lever is placed on the bearing member of the disc player. A generally flat elongated retainer member made of a thin elastic plate is formed at both its ends with engagement means for engagement with the circumferential grooves of the guide pins, when it is placed on the disc eject lever, to retain the disc eject lever. The engagement means of the retainer member includes a pair of keyhole-shaped holes having wider portions arranged at a greater spacing than that of the guide pins for allowing the guide pins to easily extend therethrough when the retainer member is slightly bent, and narrower portions arranged at a spacing substantially equal to that of the guide pins for snugly fitting therein the circumferential grooves of the guide pins when the retainer member is allowed to extend flatly on the disc eject lever.
