Abstract

PURPOSE:To reduce the quantity of the unbalance of a rotor before dynamic balance adjustment and to facilitate the dynamic balance adjustment by arranging a pedestal on the opposite side from the bearing of a rotor about a polygon mirror and forming it integrally with a rotor rotary shaft. CONSTITUTION:A main shaft 5 consists of the rotary shaft 5B of an optical deflector and the pedestal 5A formed integrally with the rotary shaft 5B. Namely, the pedestal 5A where the polygon mirror 4 is positioned on the rotary shaft 5B is arranged on the opposite side from the bearing 9 of the rotor about the polygon mirror 4, so the pedestal 5A can be formed integrally with the rotary shaft 5B, and the center axis of the pedestal 5B is aligned with the center axis of the rotary shaft 5B. Further, the polygon mirror 4 can be pressed against the pedestal by pressing the polygon mirror 4 away from the bearing 9. Consequently, the quantity of dynamic unbalance before the dynamic balance adjustment is small and the dynamic balance adjustment is facilitated.
