Abstract: The disc device that includes a disc tray which stores a plurality of stacked discs, a tray carrier which transports the disc tray, and a disc selector which supplies one disc of the plurality of discs stacked on the disc tray to a drive unit. The disc selector includes a disc selector spindle that supports the plurality of discs, a disc press on which an upper surface of an uppermost disc of the plurality of discs supported by the disc selector spindle abuts, a displacement amount detection mechanism that detects a displacement amount of the disc press displaced according to thicknesses of the plurality of supported discs, and a thickness detection unit that detects a thickness of each of the plurality of discs based on the detected displacement amount of the disc press.

Abstract: The disc device comprises disc selector spindle that hold discs in a stacked state, separate lowermost disc from other discs, and supply separated lowermost disc to drive unit. The disc selector spindle includes first, second, and third support claws that move to storage position at which each support claw is stored inside center hole of disc and protrusion position at which each support claw protrudes in a region located in the vicinity of inner diameter of disc in plan view. First support claw moves to storage position and protrusion position independently of the movements of second support claw and third support claw. Second support claw is disposed so as to be shifted from third support claw in a stacking direction of disc by a thickness of one disc, and to move from storage position to protrusion position at a timing different from a timing of third support claw.
