<p>PROBLEM TO BE SOLVED: To set a character pattern as users wish in a short time with a simple input operation by automatically defining the character pattern based on an inputted marking zone and the character or the character string. SOLUTION: The starting No. being currently displayed on the screen of a display is identified with a controller 38, and corresponding picture drawing data and condition data are retrieved from a memory. Next, a YAG laser oscillator 22 and a He-Ne laser 24 and operated with the controller 38 through a YAG laser power source part 34 and a He-Ne laser power source part 36, and a YAG laser beam LM and a guide light beam LG are respectively turned on. And a scanning control signal corresponding to retrieved drawing data and condition data is sent to a scanning head 20, the beam spot of the YAG laser beam LM and the guide light beam LG are scanned once on the surface of a work W, and the pattern based on the starting No. is drawn on the surface of the work W. The marking is normally finished with one time scanning.</p> |
