Abstract

PURPOSE: To achieve the cost reduction of the device by controlling the frequency of carrier based on the measured values of light beam scanning line position.
CONSTITUTION: An ultrasonic light deflector 8 is installed between a light modulator 2 and a rotary polyhedral mirror 4 and a light beam scanning line position measuring means 10 near the scanning start point of a light beam, respectively. These are connected by way of an ultrasonic light deflector control circuit 9. The carrier frequency of the ultrasonic light deflector 8 is controlled via ultrasonic light deflector control circuit 9 by the use of the output of the light beam scanning line position measuring device 10 to deflect the light beam incident to a rotary polyhedral mirror 4 in the rotating axis direction of the rotary polyhedral mirror 4 so that the scanning line position in the light beam scanning range becomes a specified position. Thereby, the fluctuations of the light beam scanning line position are corrected to high accuracy without enhancing the accuracy of the light beam scanning means.
