ABSTRACT:
An optical character reader for conversion of information to a machine readable code from a strip of aplha-numeric characters on the face of a document. It includes an elongated document slot along which the document may be hand guided through a predetermined path. Optical viewing means is provided across a scan line intersecting the path of the alpha-numeric characters. A character scanning assembly electronically generates images of each character. Recognition processing means encodes these images into a machine readable code. All of the physical, optical and electronic components are contained within a compact single enclosure. Optical viewing is accomplished on a separable frame assembly having a surface area adapted to engage the document. The frame includes at least one light guiding slot and an intersecting view slot or aperture. An upright ventilation duct intersects the light guiding slot. Convection air currents created by the heated lamps are utilized to assure movement of air and dust particles in the area of the narrow viewing slot.
