Abstract: The present invention employs a method of choosing between the output of two different character recognition systems to improve the rate at which characters are recognized, without significantly increasing the number of undetected substitution errors. If the first recognition system cannot recognize a character, a random probability generator is used to determine whether to use the output of the second recognition system, or alternatively to generate a reject character.

Abstract: Magnetic ink character recognition apparatus includes a plurality of magnetic sensors (30) in a multi-gap read head (16). The signal produced by each sensor (30) in response to a particular portion of a character (26) on a document (12) which traverses it, is processed by a preamplifier (31), an amplifier and filter (32) and a full wave rectifier (33). The output of the rectifier on line (35) is delivered to a binary detector (34), to an analog OR circuit (37) and to an analog summing circuit (39). The output of the summer on line (40) is modified by being limited above a threshold level by an operator (41). The output of the OR circuit (37) is the highest from the sensors (30) and controls a track and hold circuit (46) whose output on line (45) is compared with the output of the operator (41) on line (44) in a detector (43). When the output on line (44) is large with respect to that on line (45), a double document signal is raised on line (47) and used to guide the multiple document concerned to a special reject bin.
