ABSTRACT:
A raster input scanner having a movable carriage bearing at least one scanning array, illumination lamp, lens, and mirrors, the carriage being operatively disposed in scanning relation to a transparent glass platen on which the document original to be scanned rests, and with a platen cover for overlaying the platen and the document original thereon during scanning, the inside surface of the platen cover being corrugated and covered with a highly reflective material to expose, through specular reflection, the scanning array to intensely bright light whenever the cover inside surface is scanned enabling the boundaries of the document original to be identified and image signals not associated with the document original to be discarded.
