Abstract: A holder, into which a disk is inserted from above and having an opening in its lower portion, is provided in the interior of a panel whose lower end is supported pivotably on a chassis. The panel is provided so as to translatable between a first position in which with the panel closed from an open position the holder comes into contact with the chassis and a center hole in the disk is brought near the fore-end of a turntable, and a second position in which with the panel further closed from the first position with the holder being in contact with the chassis, the disk is fitted onto the turntable. The stop is supported pivotably on the panel, and its free-end enters a lower portion of the holder so as to receive the disk. The chassis is provided with a protuberance for pivoting the stop in a direction in which, in association with the panel pivoting from the first position to the second position, that the stop comes out of abutment with the disk.

Abstract: A positioning mechanism for preventing a slider from inadvertently moving laterally comprises a projecting wall provided on a lower surface of a tray and having a first wall extending forward and a second wall extending from the first wall toward a direction orthogonal to the first wall, and at least two projections provided on the slider for holding therebetween the second wall when the tray is in a completely advanced state and the first wall when the tray is in an advancing or a retracting state.

Abstract: A mechanism deck provided with a turntable for rotating a disk and movable upward or downward as coupled to a slide member comprises a subchassis having the turntable mounted thereon, and a frame fitting to the slide member and supporting the subchassis. The chassis is provided with a holding mechanism for upwardly or downwardly pivotally movably supporting the frame as fitted to the slide member through a space between the clamp support plate and the chassis. The frame is provided with a pin projecting outward therefrom and supported by the holding mechanism for restraining the frame from backlashing upward or downward, and the projecting pin has a projection for preventing the frame from backlashing laterally.

Abstract: A device for accommodating cartridge, wherein a holder allowing a cartridge to be inserted therein is pivotally supported on a chassis with the holder being biased in a closing direction, an upper door is pivotally supported at the free end portion of the holder, a first inclined surface coming in contact with the inserted cartridge and kickout piece coming in contact with the chassis when the holder rises are provided on the upper door, the upper door is biased by a spring in such a direction that a contact face closes the opening of the holder, and the upper door moves between a door opening position in which the cartridge pushes the contact face when the cartridge is inserted so as to expose the opening of the holder and the kickout piece pushes the chassis so as to lift the holder against the biasing force of a spring and a door closing position in which, as the cartridge is further inserted, the cartridge returns in such a direction that the contact face closes the opening after coming out of the contact
