PROBLEM TO BE SOLVED: To provide an optical scanner that can easily adjust the mass of a vibration mirror part accommodated in a housing.SOLUTION: A vibration mirror part 41 has a mass adjustment part 70 formed on a surface 41b on the opposite of a reflection surface 41a. The mass adjustment part 70 comprises a rib part 41c formed at a center part that is a part excluding both end parts in the longitudinal direction on the opposite-side surface. An optical scanner further includes an optical element part 80 that reflects a laser beam emitted from a second light source 32 arranged outside a housing 50 to irradiate the mass adjustment part 70 with the laser beam.SELECTED DRAWING: Figure 4 |
