Title: Document transport and scanning system for optical character recognition

Abstract: A document transport including an endless belt driven by a pair of logic controlled servo motors which precisely move a document from a feeding station through a scanning station and into a stacking station. As documents are passed through the scanning station, images of the characters thereon are projected by a scanner onto a single columnar retina. The scanner includes a single shaft which is repetitively rotated through a preselected arc by a logic controlled servo motor synchronized with the transport control system. An illumination mirror is mounted on one end of the shaft and an image mirror is mounted on the other so that illumination from a lamp is scanned across the characters to be read while the illuminated images are reflected from the image mirror onto the retina.
