Abstract
A flat storage facility includes a storage/retrieval device having a Y-direction moving member that is horizontally movable at a certain height above a storage item placement plane. A carriage is horizontally movable in an X direction on the Y-direction moving member, and a storage item gripping mechanism is provided in the carriage. The storage/retrieval device performs storage/retrieval on a storage item between the storage/retrieval device and respective storage item placement points set on the storage item placement plane. The storage item placement plane is divided into a plurality of unit sections at various heights with respect to a reference plane. When the storage/retrieval operation is performed with the storage/retrieval device, the lowering distance of the storage item gripping mechanism with respect to the carriage is adjusted according to the height of the unit section to which the storage item placement point of a storage/retrieval target belongs.
