摘要： A scan type laser marking device which scans the surface of an object conveyed in a predetermined area and applies a laser beam to the surface of the object to form a mark on the surface of the object, comprising an area storing section for storing the area; a start point coordinate storing section for storing coordinates of an irradiation start point in the area, the irradiation start point being located upstream relating to the direction of conveyance of the object; an end point coordinate storing section for storing coordinates of an irradiation end point in the area, the irradiation being located downstream relating to the direction of conveyance of the object; a mark reference point section for storing the coordinates of a reference point on the mark; and speed setting means for setting scanning speeds so that a marking operation is started when the mark reference point reaches the irradiation start point, and is ended when the mark reference point reaches the irradiation end point.

摘要： A laser marking device for describing geometric forms such as characters and symbols including at least one line element on a surface that is being irradiated with laser light for two-dimensional scanning, comprises: a laser source; scanning optics for allowing the laser light from the laser source to be deflected two-dimensionally; and a control system for controlling both the ON/OFF operation of the laser source and the deflecting operation of the scanning optics. The control system includes ROM which stores graphic data on the line elements, CPU which retrieves the graphic data from ROM and constructs a command for graphic description, GDC which receives the command and constructs both coordinate data on a plurality of points of locus and laser ON/OFF data, and line memory which, in response to a WRITE command from GDC, receives the coordinate data and laser ON/OFF data while outputting the former to the scanning optics and the latter to laser source at a given speed.
