Abstract
A high speed document manipulator providing high resolution digital video-signal output. A document transport moves the documents at a high speed for entrance, flip-over and exit, and at about one-fifth that speed for video scanning while moving for producing the video signal. Servo control provides a forward and back initial motion to obtain top to bottom scanning. The servo circuit is electrically protected. The video sensor is firmly coupled to the optical system. An elongated light source, elliptical reflector and 'cool' mirror provide an elongated transverse illuminated area on the document as it moves through.
