Abstract A disk player with disk changer functions has an elevatable stacker for storing plural disks for playback. A mechanism or elevation of the stacker relative to a main body of the player includes a motor, a threaded shaft (95) rotated by the motor and a nut (96) fixed to the bottom of the stacker in engagement of the threaded shaft (95) to allow elevation of the stacker in response to rotation of the threaded shaft. The threaded shaft has a smaller diameter than a central aperture of the disk when received in the stacker. The fixed position of the nut may be adjusted to vary relative angular position with respect to the threaded shaft. A projection (96) may be inserted into one of a plurality of apertures (903) to vary or adjust the position of the nut relative to the shaft (95).
