PROBLEM TO BE SOLVED: To provide an optical scanner capable of reducing the arrangement space of an adjustment part adjusting the direction of an optical member.SOLUTION: The rotation angle of the eccentric machine screw 113 of a first adjustment part 101 is properly adjusted to displace one end of a mirror 64a in arrow directions A and B, so that the direction of the reflection surface of the mirror 64a can be properly set and the scanning position of the surface of a photoreceptor drum 13 with a light beam L1 can be accurately adjusted and set. Since a holding member 111, a spring member 112, and the eccentric machine screw 113 constituting the first adjustment part 101 are substantially collectively arranged on the side of the reflection surface of the mirror 64a, the height of the arrangement space of the first adjustment part 101 is low so that an optical scanner 11 can be miniaturized. |
