Abstract
The recognition rate is improved and recognition errors are suppressed when recognizing magnetic ink characters. A character recognition unitcalculates the difference between the reference waveform data of each character in a character set and the character waveform data of a read magnetic ink character, and defines the characters with the smallest differences to the read character as first and second candidate characters. If scaling the reference waveforms of the first and second candidate characters creates waveforms that are similar with a smaller difference therebetween than before scaling, and the ratio between the difference B between the waveform of the second candidate and the read character, and the difference A between the waveform of the first candidate and the read character, is greater than or equal to a specific value, the character recognition unit scales and adjusts the reference waveforms to recognize the magnetic ink character
