ABSTRACT:
A polygonal mirror assembly is provided with a vibration absorption. The polygonal mirror assembly includes a motor and a polygonal mirror rotatably installed around the rotation shaft of the motor. The polygonal mirror is provided with a plurality of reflective facets. The vibration absorption device is provided for absorbing rotational vibration due to the eccentric mass of the polygonal mirror, by elastically moving in the radial direction of the polygonal mirror. Therefore, the linearity of a scan line scanned from the laser scanning unit to the photoreceptor medium can be maintained.
