  • Patent number: 8122461
    Abstract: An optical disc device is disclosed. In the optical disc device, a cam portion configured to include a holder that is supported on the outside of a cam member to turn and move vertically is provided in a position that is in vicinity of a tray being supported by elevator cam gears. In disc loading/ejecting operations, the cam portion is turned and a projecting portion pushes down a tray projecting portion of the tray, so that a space S if formed between the tray and the disc. Since the tray is shaped into a closed circular tray, a rigidity of the tray can be ensured and also the space used to avoid a contact between a projecting portion on a lower face of the disc and a surface of the tray can be provided by bending the tray.

  • Patent number: 8020178
    Abstract: An optical disk device has superior vibration characteristics by preventing vibration of a rotating arm. A desired optical disk is selected from the plurality of optical disks which are stacked and accommodated. The rotating arm is rotated to a working space provided for the desired optical disk. A turntable is positioned, and an optical head is moved to perform the recording/reproduction. Because the tip part of the rotating arm of a cantilever structure is supported by a support member extending along the axial line CL of the optical disk, it has a structure supported by both ends. Thus, the vibration of the rotating arm can be prevented. Because the support member extends along the axial line CL of the optical disk, it passes through a holding hole at the center of the optical disk and a notch provided at the center of a tray, without interference on its way, thereby supporting the rotating arm.

  • Patent number: 7836462
    Abstract: An optical disk device is capable of reducing a thickness of a loading portion equipped with plural sheets of trays. Trays installed in a main body are energized to put an optical disk between them in the thickness direction. Therefore, a thickness of plural sheets of trays can be reduced by cutting down a clearance between the tray and the optical disk. Also, plural sheets of trays are energized by spring members to be put elastically between them in the thickness direction. Therefore, an excessive pushing force is not applied to the optical disk loaded on the tray. Also, a hollow portion of the tray is formed such that projection portions protruded in excess of a standard thickness dimension of the optical disk do not interfere with the tray. Therefore, even when the projection portions are protruded from an adapter, such adapter can be loaded on the tray.
