ABSTRACT:
A scanning device scans the entire surface of a character pattern, and a memory device stores therein the binary coded character pattern information obtained from the scanning device, and a peripheral pattern detector recognizes in turn the character pattern information of the memory device in the side direction of the character pattern to detect the outer contour of the kanji character of the character pattern, and in accordance with the information of said kanji character outer contour a peripheral pattern information pick-up circuit picks up the information items of four peripheral sides of the kanji character pattern. These information items are coded by a coding circuit and the information items thus coded are utilized for classifying kanji characters being recognized into large groups.
