Each disk holder has a recessed portion for receiving a disk therein such that the disks are horizontal, and projections which are slidably connected to the housing such that the disk holders are only movable in a vertical direction within the housing. The selecting member is slidable in the horizontal direction and includes a plurality of elongated guide grooves, each elongated guide groove receiving the projection extending from one of the disk holders such that movement of the selecting member relative to the housing causes movement of a selected disk holder in the first direction. The driving member is mounted on a drive base which pivots to position the driving member under the disk.
