Patent ID: 7107603

Claim:
A disk device comprising a mechanism unit, comprising: a rotational drive unit for driving a disk; a clamp mechanism for clamping the disk to the rotational drive unit; and a conveying mechanism for conveying the disk toward the rotational drive unit, wherein the mechanism unit comprises an attitude set-up member, which is connected to the clamp mechanism and the conveying mechanism and rotates about an axis parallel to the surface of the disk mounted in the mechanism unit, and a drive mechanism for applying a rotational force to the attitude set-up member, wherein when the attitude set-up member rotates in a predetermined direction, the clamp mechanism is operated to cancel the clamping of the disk, and the conveying mechanism is set to be able to convey the disk by the rotational force of the attitude set-up member, and wherein when the attitude set-up member rotates in a direction opposite to the predetermined direction, the clamp mechanism is set to clamp the disk, and the conveying mechanism is set not to apply a conveying force to the disk by the rotational force of the attitude set-up member, wherein the clamp mechanism comprises a clamp chassis for rotational operation, and wherein by the power of the drive mechanism, the clamp chassis is rotationally driven while the attitude set-up member is rotated by the rotational force of the clamp chassis.
