A conductive-pattern recognition apparatus is provided, which makes it sure to recognize a conductive pattern accurately. This apparatus is comprised of (a) a main electrode roller formed by circular main electrodes and circular insulators arranged alternately along a straight line and coupled together, (b) a pressure-sensitive rubber layer fixed onto an outer surface of the main electrode roller and contacted with the main electrodes and the insulators, (c) a moving mechanism for moving a specimen with a conductive pattern in a direction perpendicular to a rotation axis of the main electrode roller so that the specimen applies a pressure to the pressure-sensitive rubber layer, (d) a conduction detector for detecting electric conduction among at least two ones of the main electrodes of the main electrode roller through the pressure-sensitive rubber layer, and (e) a rotation detector for detecting a rotation amount of the main electrode roller. When a part of the pressure-sensitive rubber layer is contacted with the conductive pattern of the specimen, the part of the pressure-sensitive rubber layer causes electric conduction among corresponding ones of the main electrodes of the main electrode roller, thereby recognizing the conductive pattern of the specimen by using the conduction detector and the rotation detector.
