ABSTRACT:
An optical scanning apparatus includes light beam emitter that emits a plurality of light beams, such as laser beams having different wavelengths, respectively; light beam deflector that deflects the plurality of light beams emitted by the light beam emitter that scans an object; guider that guides the plurality of deflected light beams so that the deflected light beams fall at about the same position on the object; light receiver that receives the reflected light beams reflected from the object of reading; and image information generator that generates image information representing the object based on the reflected light beams. The optical scanning apparatus may further include an image recording system which has recording light beam emitter that emits a recording light beam based on the generated image information; deflector that deflects the recording light beam emitted by the recording light beam emitter to scan a photoconductive body that records an image represented by the image information; and recording light beam director that directs the deflected recording light beam toward the photoconductive body to record an image represented by the image information on the photoconductive body.
