Abstract

PURPOSE: To perform arbitrary scanning of light beam with high accuracy by comparing the output signal of a detecting means with the reference signal showing the desired light beam position and so correcting the control signal of the light beam scanning means that the difference thereof is made an allowable range.
CONSTITUTION: A light beam scanning means which is driven by electrical control signal and a means 17 which detects the position of the light beam scanned by this light beam scanning means are provided. A light beam scanning control unit 5 which compares the output signal E of this detecting means 17 with the reference signal showing the desired position of the light having been beforehand determined and so corrects the control signal V of the light beam scanning means that the difference of these both signals is within the predetermined allowable range is provided and a reflecting mirror 11 which drives the light beam is operated with a galvanometer 10 by the control signal V. Such constitution permits the arbitrary scanning of the light beam with high accuracy.
