Abstract
A large document scanner has a transparent top plate glass plate large enough to support an E size drawing. The base of the cabinet supports a trapezoidal mirror tilted up from the bottom with the larger parallel side above the bottom. The image of a document on the transparent plate is reflected by the trapezoidal mirror to a digital imaging camera system having a mechanically displaced electronically scanned array located inside the cabinet to the side. Tubular lamps located adjacent to bowed out upper sides between upper and lower planar reflectors illuminate the document on the transparent top glass plate.
