<p>PROBLEM TO BE SOLVED: To provide a laser marking device with which marking information can be printed without a variation in depth of printing. SOLUTION: For such a line segment element as a line segment L11 which is not divisible by the length of a reference distance interval d10 and yields a fraction of distance, a plurality of coordinate data at every reference distance interval d10 are generated from the start point S to the short of the terminal point E of the line segment, and a coordinate datum of the terminal point is generated. Every coordinate datum of points from the start point S through the short point of the terminal point E is given at every time interval t, and thereafter the datum of the terminal point E is given at a time interval t' which corresponds to the proportion of the length of the segment distance q10 to the reference distance interval d10, to a galavanoscanner 20, respectively. Thus, the printing is performed at a speed equal to that for a line segment element L10 which is divisible by the length of the reference distance interval d10 and the variation in the depth of printing is not generated.</p> |
