Abstract

PURPOSE:To decrease generation frequency of a read error and a read rejection, by exactly deriving an inclination of a character-string, when reading a character. CONSTITUTION:A correcting value (h) of a character for an OCR is stored in advance in a correcting value storage part 6. A character pattern string which has photoelectrically converted a character-string of 1 line portion is stored in an image buffer 2. This character pattern string is cut by 1 character unit in a detect-cutting part 3, position information is derived, and a recognizing part 4 outputs a result of recognition as a character code. Subsequently, the correcting value (h) is read out from the character code information, and a position of a horizontal base line 1 is derived by a horizontal base line calculating part 5. A line horizontal base line calculating part 7 derives a mean horizontal base line position of a line and inclination of the line. In accordance with these 2 pieces of information, a correcting part 8 decides a line position of the next line, and outputs correcting information for cutting a pattern to the detect-cutting part 3. In accordance with this information, the detect-cutting part 3 cuts the next line exactly.
