Abstract
A light beam scanning apparatus for recording an image on a photosensitive material by scanning with an light beam having image information of the image. The apparatus includes a cylinder for holding the photosensitive material, in which the photosensitive material faces an interior of the cylinder; a light source for projecting the light beam; an image rotation optical means for transmitting the light beam projected from the light source; a driver for rotating the image rotation optical means about the central axis, in which the image rotation optical means rotates the light beam projected from the light source at a rotating speed twice the rotating speed of the image rotation optical means; a light beam magnifying means for transmitting the light beam rotated by the image rotation optical means and magnifying the light beam so as to expand a diameter of the light beam; a light beam deflection means for transmitting the light beam magnified by the light beam magnifying means and changing a direction of the light beam so as to direct the light beam onto the photosensitive material; and a driver for rotating the light beam deflection means about the central axis synchronized with a rotation of the light beam so that the image is recorded on the photosensitive material by scanning with the light beam.
