Optical disk drive configured to incline a chuck pulley relative to a turntable

摘要

Provided is an optical disk drive including a turntable on which an optical disk is mounted and which rotates the optical disk, a chuck pulley movable in the direction of an axis of the turntable between a first pulley position spaced from the turntable and a second pulley position which is close to the turntable and in which the chuck pulley grips the optical disk together with the turntable, the chuck pulley being attracted toward the turntable by a magnetic force, and a pulley operating mechanism for moving the chuck pulley between the first pulley position and the second pulley position. The pulley operating mechanism, at the time of moving the chuck pulley between the first pulley position and the second pulley position, inclines the chuck pulley in relation to the turntable, and brings the chuck pulley closer to or away from the turntable.

主权项

1. An optical disk drive comprising:
a base frame; a turntable coupled to the base frame, the turntable being configured to receive and rotate an optical disk about an axis; a chuck pulley having a central axis and being configured to be movable relative to the base frame and the turntable, between a first pulley position spaced from the turntable and a second pulley position which is close to the turntable and in which the chuck pulley grips the optical disk together with the turntable, the chuck pulley being attracted toward the turntable by a magnetic force; and a pulley operating mechanism configured to move the chuck pulley between the first pulley position and the second pulley position, wherein the pulley operating mechanism, at the time of moving the chuck pulley between the first pulley position and the second pulley position, moves the chuck pulley from the first pulley position in which the central axis is parallel to the axis of the turntable, to an intermediate position in which the central axis is inclined in relation to the axis of the turntable, and to the second pulley position in which the central axis is again parallel to the axis of the turntable.
