PURPOSE:To ensure the extent of travel control by operating a support runner for hanging a partitioning panel and a drive runner connecting the former through a connecting shaft both via partition starting and stopping means and storage starting and stopping means. CONSTITUTION:Light L1 of a partition starting light emitting tube 74 at the outside of a storage 83 is perceived by a partitioning light receiving tube 46 of a partitioning panel 1, while a drive runner 18 is rotated by a traveling motor 2, making it travel together with a support runner 13 for hanging the panel 1 connected to the runner 18 through a connecting shaft 19. Next, each runner 18 in front and in the rear sides is differentiated with each other via a differential gear 7, and thereby travel at corner parts 66a, 66b is smoothed. Next, reflected light to a wall 76b from a travel stopping phototube 67 of the panel 1 is perceived by the phototube 67, stopping the motor 2. At time of storage, storage starting and stopping phototubes 50, 48 are used for the end. With this constitution, travel control can be done without fail. |
