To recognize visually/audibly that a tray is empty by operating a tray transfer means and a sound signal generation means when a disk detection sensor detects that disk is not held yet showing the empty of the disk, moving the empty tray to an eject position and sounding a speaker.

The disk detection sensor 4 outputs a detection signal of no disk when a placing surface is empty. A system controller 16 operates a sound signal generation circuit 9 when a CD1 is empty is judged, and operates a loading mechanism part 3. Further, when a mode becomes a continuous performance mode by setting of a user, when reproduction of all CD1 is ended, the disk detection sensor 4 outputs the detection signal of no disk, and the system controller 16 operates the sound signal generation circuit 9 and the loading mechanism part 3. A message of (Please, input a disk to a tray) is sounded. A rotary tray moves an empty slide tray to the eject position to open the tray.
