An elastic restriction section (), formed in a substantially cylindrical configuration and having the vertical axis is provided to protrude on one side of a rear end section of a chassis () formed of a synthetic resin. The chassis constitutes a case body for housing a main body that performs processing of reading or recording of an optical disk. The elastic restriction section () is divided into three elastic members that are elastically deformable into a diameter-reduced state, and provided to protrude at a position substantially diagonally opposite to an engagement position of a movement gear () of an open/close drive unit (), the open/close drive unit () advancing/retreating a disk tray () carrying the optical disk. In the disk tray (), an engaging recess () is provided to be engaged with the elastic restriction section () at a home position. Even when vibration is applied to the disk tray () while the optical disk is processed, the vibration is absorbed by the elastic restriction section () that engages with the engaging recess () to apply restoring force in different directions, thereby suppressing noise.

A disk devicecomprising a disk cartridgeand a diskaccommodated therein. The disk cartridgeincludes a body case: opened with a window for exposing a recording surfaceof the disk; and provided with a shutterto be moved in a manner capable of opening/closing the window. The body caseis provided with: a rotating bodyin a gear shape having an outer peripheral surface exposed to the exterior of the body case; and transmissionfor transmitting the rotation of the rotating bodyto the shutter. Provided in a disk driving apparatus for recording a piece of information into or reproducing the information from the diskare: a guiding rib; and an operation rack along the disk inserting direction. Provided on an outer surface of the body caseis an operational-position determining groove.in a recessed groove shape along the inserting direction of the disk deviceand near the rotating body, and the rotating bodyis engaged with the operation rack while engaging the groovewith the guiding rib so as to conduct the positioning, to thereby open/close the shutter

A disc changer comprises a receiving unit for receiving a plurality of discs, a base unit, a playback unit and a transfer unit for transferring one of the plurality of discs to the playback unit. The transfer unit is movable in the perpendicular direction to the base unit. The playback unit has on its opposite ends swing support axes. The playback unit is swingable around the swing support axes relative to the base unit and the transfer unit, respectively. The playback unit has a gear. The base unit has a base unit-gear segment portion and the transfer unit has a transfer unit-gear segment portion. The gear is held between the base unit-gear segment portion and the transfer unit-gear segment portion so as to engage with these gear segment portions.

Disc changer

A cartridge receiving apparatus comprises a receiving unit for receiving at least one cartridge; at least one support unit for supporting the cartridge received; and a detection device for detecting a position of the support unit. A decision as whether receipt of the cartridge is completed or not is made in accordance with detection results obtained by the detection device.
