Abstract:
1. A recording media processing device comprising: a magnetic reading unit that magnetically reads a magnetic ink character recorded on a recording medium; and a character recognition unit including a computer having a CPU and a memory, wherein the character recognition unit recognizes the read magnetic ink character based on comparing reference waveform data for magnetic ink characters with character waveform data acquired by the magnetic reading unit reading the magnetic ink character, adjusts by scaling the waveform of the reference waveform data for each magnetic ink character referenced to a scaling point set in each character, recognizes the read magnetic ink character based on the difference between the reference waveform data after adjustment and the character waveform data, and when there are three peaks exceeding a specific level in the reference waveform data, sets two scaling points in the waveform of the reference waveform data and scales the waveform of the reference waveform data referenced to the two scaling points; wherein the character recognition unit makes a first adjustment that scales the waveform of the reference waveform data referenced to one of the two scaling points, makes a second adjustment that scales the waveform of the reference waveform data referenced to the other of the two scaling points, compares the difference between the character waveform data and the reference waveform data after the first adjustment with the difference between the character waveform data and the reference waveform data after the second adjustment, and recognizes the read magnetic ink character based on the smaller difference.
