[Problems to be solved by the device]

 However, in recent years, optical discs have become widespread in ordinary households, and the number of discs owned by households is increasing, and the number of discs is also increasing. Therefore, the arrangement becomes more complicated, and many discs that are not rearranged are jacketed. It tends to be piled up in a pile. For this reason, the enjoyment of using the optical disk is halved, and there is a risk that the disk will be wasted a lot, such as buying the same disk twice, or appearing a disk that is discarded without being reused. Further, when the tray on which the selected disk is placed is moved to the reproducing apparatus side by the gear meshing mechanism, the gear may be damaged if the gear meshing is poor.

The present invention has been made in view of such a conventional situation, and a stocker unit for storing a large number of discs is provided, and a tray on which the discs in the stocker unit are placed is used as a reproducing device for reproducing the discs. It is an object of the present invention to provide a disc player in which idle control gears are interposed in the tray retracting means for retracting, so that the discs can be stored in an organized manner and the gears mesh smoothly when the tray is retracted into the playback device. .
