A disk cartridge loading and ejecting mechanism for a recording/reproducing apparatus has: a cartridge holder for receiving a disk cartridge which is movable between a cartridge loading position and a cartridge ejecting position; a loading lever for moving the cartridge holder to the cartridge loading position; a protrusion provided at a side portion of the loading lever and moved integrally with the loading lever; a lock lever having an engagement portion with which the loading lever engages and an abutting portion on which a forward end of the disk cartridge is able to abut and for locking the loading lever in the ejecting position and the loading position; a sliding plate having a first and a second slanting cam portion with which the protrusion is engageable and being movable in the direction along which the disk cartridge is inserted and discharged; an ejection operation section connected to the sliding plate for moving the sliding plate in the disk cartridge insertion direction; and an elastic member for urging the sliding plate toward the ejection operation section.

Disk cartridge loading and ejecting mechanism in recording/reproducing

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.

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

A disk recording and reproducing device includes a chassis, a front panel mounted on a front side of the chassis, a disk holder movably mounted on the chassis for holding an information storage disk, and an eject button unit for operating the disk holder to allow the information storage disk to be ejected therefrom, the eject button unit being lockingly mounted on the chassis and having a portion projecting through the front panel. The eject button unit is mounted in place on the chassis before the front panel is attached thereto.

Eject button unit for a disk recording and reproducing device

A disk recording and reproducing device includes a chassis, a disk holder movably mounted on the chassis for holding an information storage disk, an eject lever slidably mounted on the chassis, a side panel mounted on the chassis, an ejector button mounted on the chassis for actuating the eject lever, a slide member slidably mounted on the side panel substantially parallel to the eject lever and actuatable in response to sliding movement on the eject lever for substantially vertically moving the disk holder between unload and load positions, the eject lever having an engagement tongue projecting toward and engaging the slide member in a direction across the direction in which the slide member is slidable.
