  • Publication number: 20120005695
    Abstract: A disk device is provided with a pair of slide cam members respectively starting movement when a disk is conveyed to a replayable position, and a pair of clamper lifters respectively having clamper support portions supporting clamper, the pair of clamper lifters are moved in opposite directions to each other in a horizontal direction orthogonal to a thickness direction of the disk device in conjunction with the movement of the pair of slide cam members, and formed so that timings to start movement in the opposite directions to each other are different from each other, and the clamper support portions have inclined surfaces being contacted with an outer peripheral part of the clamper in accordance with the movement of the pair of clamper lifters in the opposite directions to each other so as to move the clamper in the thickness direction of the disk device.

  • Patent number: 8046782
    Abstract: The tray carry-out method for a disc changer device, comprising, while transporting the tray from a recording/reproducing position to a stand-by position by driving the first motor, starting to drive the second motor for bringing a tray driving gear unit into a tray simultaneously transportable state, and upon completion of the transport of the tray to the stand-by position, with the tray driving gear unit being set to the tray simultaneously transportable state, starting to drive the second motor to carry out the tray from the stand-by position to an exchange position.

  • Patent number: 7895612
    Abstract: Two positioning levers for positioning a disk and two detecting levers are provided outside an area in a disk loading device where the disk is to be mounted. A large-diameter disk is positioned when both of the two detecting levers come in contact with the disk. At the time of insertion of a small-diameter disk when one of the detecting levers comes in contact with the disk, the two positioning levers do not move and the small-diameter disk is positioned.
