Abstract:
An optical path structure of an optical scanner assembly for introducing three or more light beams to deflector means for deflection and passing the respective light beams deflected and reflected by said deflector means through an F&thgr; lens to scan over image carriers individually, thereby forming electrostatic latent images on said image carriers, the optical path structure introducing the light beams from light sources to said image carriers, the optical path structure comprising:a pair of F&thgr; lenses arranged at symmetrical positions about an axis of symmetry passing through the center of a deflector; at least three light sources for emitting the light beams, divided into two groups arranged across the axis of symmetry; reflectors on which a first of the light beams is incident, arranged on the other side of the axis of symmetry from a first light source providing the first light beam; and other reflectors on which the remaining light beams are incident, arranged on the same side of the axis of symmetry as the light sources providing the remaining associated light beams, wherein the light beams reflected from said reflectors are reflected by deflector reflective surfaces of said deflector means lying on the same sides of the axis of symmetry as said reflectors, and introduced to said F&thgr; lenses, respectively.
