PROBLEM TO BE SOLVED: To provide a laser marking device capable of speeding up the marking, while restraining printing quality from being deteriorated through inboard turning phenomena in the curve line portion and the bending portion. SOLUTION: When the controlling means 130 grants coordinate data on a point C, a change-over angle θb is compared with the standard angle based on the coordinate data on the points A, B. The change-over angle θb is detected to be bigger than the standard angle, and when the detecting signal which alarms the marking point accessing the point B receives from the access condition detecting means 250, the coordinate data on the point C is given to a galvanoscanner 220. By this way, the inboard turning in the vicinity of the point B can be avoided. Subsequently, the coordinate data on the point D is equally delayed, but the coordinate data on the point E is given to the galvanoscanner 220 at normal timing since the change-over angle θb is detected to be smaller than the standard angle. By this way, speeding up of the marking is possible while restraining printing quality from being deteriorated. |
