<p><P>PROBLEM TO BE SOLVED: To provide a laser marking device that can surely mark a marking object with marking information even if the marking object is transported at high speed. <P>SOLUTION: In a state where a laser beam is guided to a first head part 4 through a light guiding means 10 by switching the direction of the laser beam from a laser light source 8, if an area to be printed of the marking object 16 is positioned in the printing area, the laser light source 8 and the first head part 4 are controlled, so that divided marking information is marked on the marking object 16 by the first head part 4. Successively, in a state where a laser beam is guided to a second head part 5 through a light guiding means 10 by switching an optical path switching means 9, if the area to be printed of the marking object 16 is positioned in the printing area, the divided marking information is marked by the second head part 5. <P>COPYRIGHT: (C)2004,JPO</p> |
