Abstract
Respective first semiconductor lasersandand respective second semiconductor lasersandare arranged on a drive substrate(YZ plane) such that the emission directions of light beams Lto Lof the respective first semiconductor lasersandand the respective second semiconductor lasersandare perpendicular to the YZ plane. On the YZ plane, the respective first semiconductor lasersandand the respective second semiconductor lasersandare divided to two mutually different lines yand yin the lateral direction perpendicular to the rotation axis of a polygonal mirror, and the respective first semiconductor lasersandand the respective second semiconductor lasersandare arranged on respective different lines zto zin the vertical direction as the rotation axis direction of the polygonal mirror
