Zusammenfassung:PROBLEM TO BE SOLVED: To easily, quickly, and automatically generate comparison reference data and to judge whether a mark is good or not with high precision independently of the size and the state of the mark itself. SOLUTION: The mark of indefective parts is detected by a read means 2 and is processed by a picture storage and processing means 4 to register two kinds of comparison reference data, which are generated correspondingly to characters, in a dictionary storage means 5. In this state, the mark of an examination object 1 is compared and collated with two kinds of comparison reference data corresponding to characters through means 2 and 4 by a judging means 6 to judge whether the mark is good or not with high precision in the unit of characters.
