Abstract

PURPOSE: To realize a high-speed scanning at a low cost, by applying several scanning beams to the photosensitive drum using plural circular-linear converting optical fibers.
CONSTITUTION: The 1st and 2nd circular-linear converting optical fibers consist of the cylinder parts 12A and 12B plus the linear parts 13A and 13B, and the parts 12A and 12B are distributed in a semicircular form. The laser beam 18 is reflected by the rotary mirror 15 and furthermore reflected by the tip mirror 15 of the cylinder part 12 to form a focus at the tip 12a of the part 12. With a high-speed rotation of the mirror 15, the beam 18 scans successively the parts 12a on the circumference to be radiated in succession through the tip of the linear part 13. Accordingly, the scanning is performed twice by the scanning beams 19 given from the parts 13A and 13B when the mirror 15 has one rotation, thus giving a circular scanning to the circumference surface of the photosensitive drum 20. In such constitution, a high- speed scanning is possible at a low cost.
