Claims (1)

[Scope of utility model registration request] Multiple rows of movable shelves are arranged in parallel in the running direction, each movable shelf capable of moving in a direction perpendicular to the opening surface, and each movable shelf is equipped with a reversible motor for self-propulsion. A common control circuit is provided for the movable shelves adjacent in the frontage direction among the movable shelves constituting the row, and this control circuit receives at least an open command signal and transition margin signals on both left and right sides and responds to these signals. The right row signal and the left row signal are configured to control the output of the right row signal and the left row signal, and the right row signal and the left row signal are arranged perpendicular to the frontage surface so that they are exchanged between the control circuits of the movable shelves arranged perpendicular to the opening surface. The control circuits of the movable shelves in the direction are connected to each other, and the self-propelled reversible motors of the movable shelves adjacent in the frontage direction among the movable shelves constituting each movable shelf row are connected to the right A motor drive circuit is provided to perform common forward/reverse control in accordance with the output of the row signal and left row signal, and the motor drive circuit for each movable shelf is configured to control the movement of the movable shelf depending on whether or not there is a transition margin for each movable shelf. In a movable shelf device equipped with a limit circuit for controlling the drive and stop of a self-propelled reversible motor, the transfer of control signals and the supply of motive power between movable shelves arranged in parallel in the frontage direction are performed. A mobile shelf device made by passing cables for.
