Patent abstract
An encoder 13 determines the remaining travel distance of a stacker crane to perform deceleration control. When a linear sensor 8 determines an absolute distance from the stop position, the linear sensor 8 performs deceleration control, and when a mark sensor 26 detects a mark 36, the mark sensor 26 performs stop control. Likewise, deceleration control is performed based on the remaining elevation distance determined by an encoder 19. When a linear sensor 9 determines an absolute distance from the stop position, the linear sensor 9 performs deceleration control, and when the mark sensor 26 detects the mark 36, the mark sensor 26 performs stop control.
