Abstract

See full text

Trays including disc mounting portions for mounting discs are divided into seven trays for each disc. Portions of the discs except for the disc positioned at a reproduction state overlap with adjacent discs. Accordingly, seven discs can be held despite that a diameter of an entire assembly including all seven trays rotatively moving around a central shaft is equal to that of a large tray of a conventional disc reproduction device of a carrousel type capable of holding five discs. The constitution also includes an interlocking mechanism of the discs, a sliding mechanism where the trays rotatively move around the central shaft horizontally and upward/downward obliquely while maintaining parallelism, and driver for providing a period of time in which trays at a middle stage in the beginning of one stroke and trays reaching the middle stage are still during a time period for one stroke.
