A drive mechanism moves a turntable into the expanded region between the designated tray and the disc on the designated tray to place the turntable below the pushed disc. The drive mechanism includes a shaft, a base plate supported within the casing via the shaft, a damper, and a chassis connected to the base plate via the damper and carrying the turntable.
