リゴンミラーの回転支持装置。 A mirror surface is formed on the radially outer surface of a rotating body with a polygonal planar shape, and the rotating body is supported by a shaft sleeve installed around the outer periphery of a fixed shaft and thrust plates installed above and below. In the polygon mirror rotation support device, the rotating body is rotatably provided on the outer periphery of the shaft sleeve. It consists of a ceramic rotor, an aluminum rotor with a mirror surface that is shrink-fitted to the outer periphery of the ceramic rotor, and a yoke that is shrink-fitted to the outer periphery of the ceramic rotor. A polygon mirror rotation support device characterized by having a magnet bonded to it.
