Magnetic ink character recognition apparatus and method by the same

A magnetic ink character recognition method,

• comprising:
• conveying a medium on which a magnetic ink character is printed with respect to a magnetic head
• acquiring a magnetic detection signal of the medium read by the magnetic head;
• excluding a predetermined exclusion section including a reading result of an end portion of the medium from a signal section of the magnetic detection signal;
• and
• recognizing an identity of the magnetic ink character based on the magnetic detection signal of a remaining signal section except for the predetermined exclusion section;
• further comprising:
• specifying a signal section from a first peak position of the magnetic detection signal to a position away from the first peak position by a movement distance corresponding to a time width determined according to a size in the conveyance direction of the medium and a conveyance speed of the medium, and excluding a magnetic detection signal in the exclusion section from a rear end to a tip of the signal section;
• setting as a predetermined time width calculated based on sizes of margin areas positioned in front and rear sides in the conveyance direction of a printing area on which the magnetic ink character is printed on the medium and the conveyance speed of the medium.

A check reading device, comprising:

• a magnetic head;
• a conveyance module configured to convey a check on which a magnetic ink character is printed with respect to the magnetic head;
• an acquisition module configured to acquire a magnetic detection signal of the check read by the magnetic head;
• an excluding module configured to exclude a predetermined exclusion section including a reading result of an end portion of the check from a signal section of the magnetic detection signal;
• and
• a recognition module configured to recognize an identity of the magnetic ink character based on the magnetic detection signal of a remaining signal section except for the predetermined exclusion section;
• wherein the excluding module specifies a signal section from a first peak position of the magnetic detection signal to a position away from the first peak position by a movement distance corresponding to a time width determined according to a size in the conveyance direction of the medium and a conveyance speed of the check, and excludes a magnetic detection signal in the exclusion section from a rear end to a tip of the signal section;
• wherein the exclusion section is set as a predetermined time width calculated based on sizes of margin areas positioned in front and rear sides in the conveyance direction of a printing area on which the magnetic ink character is printed on the check and the conveyance speed of the check.
