Abstract

In a magnetic ink character recognition system provided in a magnetic ink character reader, the system includes; a read unit for detecting magnetic flux generated from each magnetic ink character separately printed in every field in a check or bill, and outputting a digital signal read therefrom; a storage unit operatively connected to the read unit for storing the digital signals output from the read unit; a field sort unit operatively connected to the storage unit for receiving the digital signals from the storage unit in every field and sorting the digital read signals for each field; a decision unit operatively connected to the field sort unit for receiving the digital read signal sorted by the field sort unit, judging the thickness of the magnetic ink character in every field, and determining a representative thickness value in every field; a correction unit operatively connected to the storage unit and the decision unit for receiving the digital signals from the storage unit and correcting the digital signals based on decision data output from the decision unit for every field; and a recognition unit operatively connected to the correction unit for determining whether or not …
