Abstract: PURPOSE:To improve recognizing accuracy by exactly collating words even when a character position based on the character segmented result is shifted from a correct answer character position. CONSTITUTION:Character patterns are individually segmented from an inputted character string by a character segmenting means 1, and the characters of those individual character patterns are recognized by a character recognizing means 2.
