    Abstract: A hand-held scanner (1) is provided for reading characters from a string of characters recorded on a substrate (2). The scanner (1) may be held like a pen and moved, in contact with the substrate (2), along the string of characters. Movement of the scanner is sensed by a sensor (21). An optical system views a small area (32) of the substrate (2) and an optical detector (26) detects the relative intensity of light reflected from each of several points in the area of view (32). To facilitate tracking, a portion of the string of characters adjacent to the area of view is clearly visible to the user. The scanner includes memory for storing codes representing individual characters. The scanner may include a computer (41), connected by a cable (42), or may be self-contained and battery operated.
