Abstract
PURPOSE: To enhance resolution and achieve the improvement in printing quality by using a vibrating mirror having the conditions of being unable to increase the angle of deflection beyond a certain limit and disposing two or more sets of laser generators.
CONSTITUTION: Laser Lb out from one laser generator 7 is modulated by an acousto-optic light modulator 10. This modulated light L1a is entered to a vibrating mirror 2 via reflected light 11 and scans the scanning length of l/2 corresponding to the left half of a scanning line 4 at resolution point numbers n at the angle of deflection θ by the vibrating mirror 2. Laser light Lb out from the other laser device 8 also scans the scanning length of l/2 corresponding to the right half of the scanning line 4 at resolution point numbers n. In this way, the scanning length l/2 + l/2 = l may be scanned at 2n resolution point numbers by using the same vibrating mirror 2, hence the resolution becomes 2n/l, thus the images of high printing quality may be obtained.
