Therefore, by arranging a plurality of masks in an overlapping arrangement on the 1st floor, and moving the mask having the pattern to be printed among the 71 mask groups as appropriate so that it is located within the passage path of the laser beam, printing can be done. A laser printing device 1'1'' has been proposed in which the pattern can be easily changed. If C fluctuates, it is difficult to maintain printing quality because the laser beam used in practical use is not a perfectly parallel beam.
