PURPOSE:To facilitate to change the moving direction of a cage by stopping rotation of both end parts of a rotary rail respectively on a first position to oppose to respective elevatable guide rails, and on a second position to oppose to respective transversely movable rails. CONSTITUTION:The rotary shaft of a rotary rail 21 is journaled with a bearing, and rotational movement of the rotary rail 21 is limited with stoppers 28 on the extreme end of guide rails 22 for transverse movement from the corresponded position to elevatable guide rails 20 to the corresponded position to transversely movable rails 22 by rotational movement of 90. When alternating voltage is applied to an electromagnet 32 through a control device, the rotary rail 21 is rotationally moved in the arrow mark A direction or the reverse direction due to the principle of a linear motor, a cage fitted through a supporting part 42 is also rotated, and guided onto the elevatable guide rail 20 to ascend or descend, or guided onto the transversely movable guide rail 22 to transversely move, with a pair of rollers 46. |
