Abstract: A disk device according to the present invention includes a mechanism unit having 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. The mechanism unit further includes an attitude set-up member, which is directly 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. 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.

Abstract: In a disk apparatus in which either a large-diameter disk or a small-diameter disk can be loaded, a pair of detecting projections and a pair of positioning projections are provided in a disk loading path, and a pair of selection grooves are formed in a chassis. Each of the selection grooves includes a first guide groove and a second guide groove. The positioning projections operate inside the first grooves when the opposing distance between the detecting projections is increased by a small-diameter disk, and they are pressed into the second guide grooves by the peripheral edge of the large-diameter disk when the opposing distance is increased by a large-diameter disk. The small-diameter disk is positioned by the positioning projections placed in the first guide grooves, and the large-diameter disk is positioned by the positioning projections placed in the second guide grooves.
