摘要： A main drive mechanism provided with a main motor drives a rack on a first main path and a rack on a second main path simultaneously in the forward direction or simultaneously in the reverse direction. The rack is sent along a first auxiliary path by a first auxiliary drive mechanism. Then the rack is further sent in the forward direction along the second main path by the main drive mechanism. Once the rack leaves the first receiving region, the first claw member of the first auxiliary drive mechanism is sent to a retraction position and the rack is driven by the main drive mechanism in the reverse direction. The first claw member is then sent to an engagement position on the first main transportation path, the main drive mechanism is driven for transport in the forward direction, and the rack and the first claw member engage each other.
