PROBLEM TO BE SOLVED: To provide a method capable of printing two-dimensional codes having various shapes to a cell plate stuck to the upper surface of a Pachinko face panel during its manufacturing. SOLUTION: A positioning device B<SB>1</SB>for positioning a carrying direction Q of the Pachinko face panel P and a horizontal direction R at right angles to the direction and a laser printing unit E for printing a two-dimensional code C by a laser beam L at a specific position of the cell plate S of the Pachinko face panel P positioned in the two directions by the positioning device are disposed in the middle of a roller conveyer device D for conveying a Pachinko face panel P. At a printing position while carrying the Pachinko face panel, the Pachinko face panel P is stopped by positioning the two directions by the positioning device and the two-dimensional code C is laser printed by the laser printing unit E with respect to a specific position of the cell plate S pasted on the Pachinko face panel P.
