<p>PROBLEM TO BE SOLVED: To improve the transport capacity by widely using a traveling path by forming a slide fork to be freely turned so that the direction of expansion and shrinkage is pointed from the longitudinal direction of a transport truck toward the cross direction. SOLUTION: When a transport truck 1 is separated from a delivery device 10, a fork piece 5a of a slide fork 5 is turned at 90-degree in the reverse direction, then lowered by an elevating device, and stored in a reference position of the lower portion of a storing chamber 2. Thus, the transport truck 1 is capable of stacking cassettes 7 longitudinally by freely turning the slide fork 5, so that the width of the truck can be reduced. Therefore, the space between the delivery device 10 and the transport truck 1 can be taken large, so that the safety of a worker can be secured, and also a traveling path can be taken wide, whereby even if the transport truck 1 is in the state of being stopped in front of the delivery device 10, another transport truck 1 is enabled to overtake the truck so as to remarkably improve the transport capacity.</p> |
