  • Patent number: 6744704
    Abstract: A disk playback apparatus has a lower chassis unit carrying a stack of disk holders. A stage unit carries major components of the disk playback apparatus including side select plates for selectively lifting or lowering the disk holders, a drive base unit for playing back a disk, a horizontal driving gear mechanism for moving the drive base unit into a space which is formed as a result of the selective upward or downward movement of the disk holders, and a loading roller for loading and ejecting a disk. The stage unit is moved up and down in accordance with the position of a selected disk holder, by the power of a first motor, through the actions of a gear mechanism, mode pate and slide plates.

  • Patent number: 6574185
    Abstract: A disk player includes a selecting mechanism, a switching control mechanism, a transporting roller-actuating mechanism, and a pickup feeding mechanism. In the disk player, an idler plate pivots in response to a direction of rotation of a worm wheel that always meshes with a worm provided on a shaft of a loading motor. Three idler gears that always mesh with the worm wheel are provided on the idler plate. The idler plate couples a switching idler gear to the switching control mechanism at a disk mounting position, couples a transporting roller-actuating idler gear to the transporting roller-actuating mechanism, and couples a pickup feeding idler gear to the pickup feeding mechanism at a pickup feed position.
