Abstract
A system for producing images of documents is disclosed. The system provides varying levels of illumination to different areas of the document being recorded, depending upon relative image densities across the document. A slit aperture image area is divided into a plurality of illumination zones and the image density of each zone is sensed and adjusted individually. Efficient and orderly unattended off-loading of photographed documents is accomplished by a movable drawing member over which large documents are automatically draped, properly collated. A catch tray is provided for automatically off-loading and collating smaller documents.
