Zusammenfassung: | To provide an optical scanner that can prevent unintended outflow of an adhesive for fixing an optical member and suitably bond and fix the optical member.SOLUTION: An optical scanner comprises a light source, a polygon mirror, a reflecting mirror 53, and a housing. The housing has an adhesion support part 211 that is adhered with the reflecting mirror 53 with an adhesive G applied between the reflecting mirror 53 and the adhesion support part and supports the reflecting mirror 53. The adhesion support part 211 has projections 214 and a recess 215 that are formed on opposite surfaces 212a, 213a opposite to the reflecting mirror 53 and applied with the adhesive G and that extend in a direction intersecting a main scanning direction Dm. The projections 214 are arranged on both ends in the main scanning direction Dm of the opposite surfaces 212a, 213a. The recess 215 is arranged between the two projections 214 with respect to the main scanning direction Dm.SELECTED DRAWING: Figure 4
【課題】光学部材を固定するための接着剤の意図しない流出を抑制し、光学部材を好適に接着固定することが可能な光走査装置を提供する。【解決手段】光走査装置は、光源と、ポリゴンミラーと、折返しミラー53と、筐体と、を備える。筐体は、折返しミラー53との間に塗布された接着剤Gにより折返しミラー53が接着され、折返しミラー53を支持する接着支持部211を有する。接着支持部211は、折返しミラー53と対向して接着剤Gが塗布される対向面212a、213aに形成され、主走査方向Dmと交差する方向に延びる凸部214及び凹部215を有する。凸部214は、対向面212a、213aの主走査方向Dmの両端部に配置される。凹部215は、主走査方向Dmに対して2つの凸部214の間に配置される。【選択図】図4 |
