Abstract
A disk player capable of playing one of a plurality of disks arranged on a tray, comprises a housing, and a tray having a center and a plurality of disk rests aligned radially around the center of the tray, the tray movable between a disk loading position outside of the housing and an operating position located inside the housing the center of the tray corresponding to a disk playing position when the tray is in the operating position. A disk selecting device includes a rotatable-arm member rotatable about the disk playing position and a disk holder slidably attached to the rotatable-arm member, the disk holder reciprocatively movable between the disk playing position and one of the plurality of disk rests for moving a selected disk to be played from its associated disk rest to the disk playing position. A disk detecting device is attached to the disk holder and detects whether the selected disk is attached to the disk holder. The tray is ejected from inside the disk player housing when the disk detecting device determines that the selected disk has become detached from the disk holder during movement of the selected disk from the disk rest to the disk playing position.
