When an uppermost workpiece WH held by a holding unit 60 is drawn out by a robot 3, a receiving table 100 can receive and support a bottom face WH1 of the drawn uppermost workpiece WH. When it is determined by a control unit that a lower workpiece WL exists under the uppermost workpiece WH, the receiving table 100 advances toward a slide base 80 at a speed synchronized with the drawing speed so that a top distance D1 between a leading end of the receiving table 100 and a front face WL2 of the lower workpiece WL facing the leading end of the receiving table 100 is kept at a first distance before and after the uppermost workpiece WH held by the holding unit 60 is drawn out by the robot 3.SELECTED DRAWING: Figure 9
