Abstract (en)
[origin: WO8405005A1] A high speed document manipulator providing high resolution digital video-signal output. A document transport (10) moves the documents (2) at a high speed for entrance (1) flip-over (31) and exit (30), and at about one-fifth that speed for video scanning while moving for producing the video signal. Servo control (43) provides a forward and back initial motion to obtain top to bottom scanning. The servo circuit is electrically protected (70). The video sensor (18) is firmly coupled to the optical system (17). An elongated light source (20) elliptical reflector (21) and "cool" mirror (22) provide an elongated transverse illuminated area on the document as it moves through.
