Improved structure of stocker apparatus for storage medium

摘要

A stocker apparatus for storage mediums such as minidisk cartridges is provided which includes a stocker tray moving mechanism designed to move stocker trays between a neutral and a storage medium loading/unloading position together. In the neutral position, the stocker tray moving mechanism lays the stocker trays (16,17,18) to overlap each other with storage medium loading/unloading openings being aligned vertically. In the storage medium loading/unloading position, the stocker tray moving mechanism shifts the stocker trays laterally by different distances so as to orient the storage medium loading/unloading openings diagonally upward for facilitating ease of manual loading and unloading of each storage medium into and from corresponding one of the stocker trays. <IMAGE>
