Abstract
A document illumination system adapted for use in a jet drop copier or duplicator. A pair of focussing reflectors collect illumination from two parallel line source illuminators and direct the collected illumination toward a pair of scanning mirrors. The scanning mirrors, together with a pair of side mirrors, direct narrow beams of illumination toward a common illuminated strip on the face of a document positioned on a flat document support member. The scanning mirrors are scanned in synchronism to move the illuminated strip back and forth along the face of the document, and the reflectors are concomitantly moved in synchronism to maintain an image of the illumination sources in one dimensional focus at the surface of the document. All motion of the scanning mirrors and the reflectors is produced by a single drive motor, which drives a set of interspersed timing belts to produce uniform rotary motion of the input shafts for four conjugate cam arrangements. The conjugate cam arrangements are appropriately configured for producing the requisite motion of the reflectors and the scanning mirrors.
