Abstract

PURPOSE: To simplify the constitution of the recorder of many resolution point numbers and a wide scanning width by driving an acousto-optic modulator at plural different frequencies and deflecting the modulated light in different directions.
CONSTITUTION: The signals of different frequencies outputted by oscillators 9, 10 according to the picture signals corresponding to the front and last halves of images are modulated by modulators 11, 12 and are applied to an acousto-potic light modulator 15 via coupler 13. This causes the primary laser beams modulated according to the front and last half imaged from the leser 16 to be deflected in mutually different directions. These laser beams enter the scanning mirror, etc. 5 at different incident angles via mirrors 18, 20 and simultaneously radiate and scan the front and last halves of a recording photoreceptor 7. Hence, recording of many resolution point numbers and a wide scanning width by the laser beams of narrow scanning angles is accomplished by the simple constitution using one set of light sources and acousto-optic lighr modulator.
