Abstract
The illumination of a document moving through an exposure zone is maximized by placing a pair of reflectors on each side of the exposure zone in close proximity to the object plane and in an optimum reflecting position in relation to the illumination source. In a first embodiment, utilized in a continuous velocity transport (CVT) system, the reflectors comprise an integral member consisting of a plurality of connected facets. In a second embodiment, wherein the document is moved across a fixed platen, the reflectors effectively consist of two elements including a physically separated extended portion which is formed within the cross section of the platen.
