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.
