PROBLEM TO BE SOLVED: To provide the optical scanning device which is made small-sized and can display excellent image formation characteristics. SOLUTION: A deflector 10 consists of an optical deflecting element 20, a driving part which places the optical deflecting element 20 in sine vibration, and a deflector housing 22, and at both the ends below the reflecting surface side of the deflector housing 22, a cylindrical rotary shaft 23 which is formed integrally with the deflector housing 22 is fitted to a bearing 20 molded in the same body with the housing 2. Further, a tilt adjustment part 26 consisting of an adjusting screw fitting plate 24 and an adjusting screw 25 is formed at the lower part of the back surface of the deflector housing 22. Then the tilt quantity of the deflector housing 22 can be adjusted by rotating the adjusting screw 25, so the angle of the reflecting surface of the reflector 45 can be adjusted and a laser beam can be reflected to a desired direction. |
