Electrically-operated shiftable article storage device

摘要

An electrically-operated shiftable article storage device in which a plurality of shiftable article storage units adapted for movement in a direction normal to the article storage faces thereof to form a plurality of article handling aisles therebetween are normally arranged closely adjacent to each other to leave a limited space corresponding to at least one article handling aisle, and at least one of the article storage units is moved in either direction to form said article handling aisle opposite to the article storage face of a desired one of said article storage units so that articles can be handled in said article handling aisle. In the device, a confirmation switch is disposed for each article handling aisle at a position at which the state of the corresponding article handling aisle can be readily confirmed, so that the article storage units cannot be moved unless the confirmation switch associated with an already existing aisle is actuated before causing shifting movement of one or more of the article storage units to form a new article handling aisle.
