PROBLEM TO BE SOLVED: To enable printing with high positional accuracy to a gas permeable workpiece.SOLUTION: The gas permeable workpiece W such as carbon paper is sent out by a sending-out roller 21, and is sent to a printing position by a suction roller 3, and is wound by a winding roller 22 after printing by a printing unit 1. A cover film 5 is positioned in the vicinity of a suction port 310 of the suction roller 3 sucked by a suction mechanism, and the workpiece W is brought into close contact with the suction roller 3 so that the cover film 5 is sucked to the suction roller 3 in a state of sandwiching the workpiece W in-between. When sending the workpiece W by rotating the suction roller 3, the cover film 5 is sent by a cover sending mechanism 7 by synchronizing with sending of its workpiece W. |
