Abstract
A flat storage facility includes a storage/retrieval device having a Y-direction moving member with a length corresponding to the width of a storage item placement plane in an X direction and that is movable in a forward/backward Y direction of the storage item placement plane. A carriage is supported on the Y-direction moving member and is movable in the X direction. A storage item gripping mechanism is supported on the carriage so as to be freely raised and lowered. Lowering of the storage item gripping mechanism is controlled such that downward flexural deformation distances between end portions of the Y-direction moving member in the X direction are determined. Lowering distance adjustment values of the storage item gripping mechanism for the storage item placement points are set based on the downward flexural deformation distances, and lowering distances of the storage item gripping mechanism are reduced by the lowering distance adjustment values.
