PROBLEM TO BE SOLVED: To adjust discharge speed and discharge timing of a workpiece sheet by responding to the change in the diameter of printing rollers even if it is caused by the difference of thickness of a printing die, and enable position setting and discharge suitable for each workpiece sheet in accordance with the thickness and length or the like of the workpiece sheet. SOLUTION: The device for discharging workpiece sheet is provided with a plurality of paper feeding rollers 3 for discharging a workpiece sheet W1 in the lowest layer out of stacked workpiece sheets W to a printing unit S2 side, a great 4 for adjusting protrusion amount with respect to the plurality of paper feeding rollers 3 by lifting/lowering movement and adjusting contact/separation of the plurality of paper feeding rollers with/from the workpiece sheet W1 in the lowest layer, drive means M4a, M4b for lifting/lowering the great 4, a drive means M3 for rotating the plurality of paper feeding rollers 3 and arranged separately from the drive means M4a, M4b of the great 4, and a control means 11 for controlling these drives. The control means 11 cooperates with drive of the printing rollers Rn (n=1, 2, etc.) of the printing unit S2. COPYRIGHT: (C)2009,JPO&INPIT
