Abstract

A disk player with disk changer functions and having a stacker for storing plural disks for playback allows a new disk to be added or disks to be changed without removing the stacker. The disk player is also convenient for playback of single disks not to be stored in the stacker. A single tray carrying one of disk-carriages is transportable between a loaded position inside the player and an ejected position outside the player, by means of a shuttle engageable with the tray. During further movement of the shuttle in the disk-loading direction, it is disengaged from the tray in the loaded position. Instead, the shuttle comes into engagement with the carriage formerly carried by the tray, to separate the carriage from the tray remaining in the loaded position and advance the same toward the stacker. The carriage is at last received fully in the stacker with the help of a spring, which releases engagement between the shuttle and the in-stacker carriage.
