<p>PROBLEM TO BE SOLVED: To provide a laser marking device capable of shortening transfer time in non-printing transfer class interval. SOLUTION: The control means 130 gives first coordinate data on the leading end point (P0) of non-printing transfer class interval, and next, coordinate data on a temporary closing end point P1F to a galvanoscanner 220 side. And, when an access condition detecting means 250 detects that the marking point accesses the temporary closing end point P1F, namely, when the marking point moves by distance L2 from the closing end point P1 to the temporary closing end point P1F side, the coordinate data on the closing end point P1 is so composed as to give to the galvanoscanner side 220. And, the distance L2 is set within the distance where residual magnetic flux does not occur practically when controlling current to the operating portions 220X, 220Y is suspended. Accordingly, the marking point can arrive at the closing end point P1 without practically receiving a torque through residual magnetic flux.</p> |
