Abstract
PURPOSE: To reduce the turn-back shock in the reciprocative movement of an optical scanning means by providing a light source near photosensitive surface and reverse-projecting the light source image to near the original surface by an imaging element.
CONSTITUTION: A light device 8 has a light source 9 for lighting at its center and is enclosed by a reflecting shade 10. The reflecting shade 10 is constituted by quadratics such as ellipsoid or poly-planes so as to lead the light of the light source 9 for lighting to an imaging element 5. A condenser lens 11 for obviating the deversion of the light of the light source 9 for lighting is porivided. The reflecting shade 10 has two openings other than at the portion of the condenser lens 11; the opening 12 lighting the region 13 on a moving photosensitive surface 3. There is a condenser lens 14 in the another opening and lens 14 is lighting the region 16 on the moving photosensitive surface 3. In this way, the light source of the lighting device 9 is projected and imaged to the position 17 near the original surface by the imaging element 5. By providing the light source near the image plane area of the photoreceptor in this way, the moving speed of the optical scanning means may be decreased and the turn-back shock in the reciprocating motion reduced.
