An autochanger type optical compact disc player includes a tray for holding a large number of discs in close proximity, a disc selection mechanism for selecting a disc from the tray, a disc port for entering a disc from the outside of the player, a disc playback mechanism for playing a disc, a first loading mechanism for transferring a selected disc from the tray to the disc playback mechanism, a second disc loading mechanism for transferring a disc from the port to the disc playback mechanism, an unloading mechanism for selectively returning a disc to the tray or to the port, and a control section for controlling operations of the player. A disc is returned from the tray by a roller for contacting the edge of the disc during movement through a limited arc to impart rotational force to the disc.
