1. An article storage facility comprising:
an article storage shelf having storage portions for storing articles, each storage portion being configured such that an article is moved into and out of the storage portion along a front to rear direction of the shelf, the storage portions being arranged in a vertical direction and a transverse width direction of the shelf, the transverse width direction being horizontal and perpendicular to the front to rear direction of the shelf; a transport device that transports articles, one at a time, laterally along the transverse width direction and vertically to the plurality of storage portions arranged along the transverse width direction and the vertical direction; a transfer device that is provided in the transport device and that transfers the article to and from the storage portion by moving the article in and out of the storage portion along the front to rear direction, the transfer device being configured to be movable in a movement space in the vertical direction and the transverse width direction of the shelf, the movement space being located in front of the article storage shelf with respect to the front to rear direction; an elevating scaffold capable of ascending and descending in a movement space between a withdrawal height, the withdrawal height defined above a movement range of the transfer device in the movement space in the vertical direction, and working heights that are defined at intermediate locations in the movement space in the vertical direction; and a support body provided for each of the working heights for supporting the elevating scaffold when the elevating scaffold is located at corresponding one of the working heights, wherein at least the support body provided for each of the working heights other than a lowermost one of the working heights is a movable support body that is configured to be movable to an acting position at which said support body protrudes toward the movement space so as to support the elevating scaffold and a withdrawal position at which said support body is retracted toward the article storage shelf so as not to come into contact with the elevating scaffold as the elevating scaffold ascends and descends, and wherein the elevating scaffold is configured to be suspended and supported by a wire that is let out from a manually operated take-up roller and to ascend and descend with rotation operation of the take-up roller, a regulating device is provided that regulates rotation of the take-up roller when the elevating scaffold has moved down to one of the working heights, and the regulating device comprises a movable body that moves as a result of rotation operation of the take-up roller and one or more regulating bodies for restricting rotation of the take-up roller by coming into contact with the movable body when the elevating scaffold has moved down to corresponding one or more of the working heights, and the height at which rotation of the take-up roller is restricted can be selected from the working heights by changing the position at which the movable body comes into contact with one of the one or more regulating bodies. |
