  • Disk device
    Patent number: 7937719
    Abstract: A disc device includes a casing, a disc processor, a drive motor, a transfer unit and a disc clamper. The transfer unit transfers an optical disc while holding the optical disc by driving the drive motor. The disc clamper switches a drive transmission of the drive unit in accordance with a holding condition of the optical disc with different diameters by the transfer unit to pivotally move the disc processor. The drive of the single drive motor effects both the transfer of the optical disc and the pivotal movement of the disc processor. A timing for transferring the optical disc and a timing for pivotally moving the disc processor can be suitably adjusted in accordance with the diameter of the optical disc.
