A device for detecting positioning marks for cutting a ceramic laminated body having a plurality of inner electrodes formed therein and having a plurality of positioning marks for cutting so formed on its outer side surfaces as to have a predetermined positional relationship with the inner electrodes, which comprises a device for detecting image information obtained from the outer side surfaces of the ceramic laminated body, a binary-coding device for binary-coding the image information detected by the detecting device based on a color density, an image memory for storing the image information binary-coded by the binary-coding device, a characteristic extractor for extracting signal regions having a color density not less than a predetermined color density from the image information stored in the image memory, removing regions having an area not more than a predetermined area and regions having a length in the lateral direction not less than a predetermined length out of the signal regions extracted, and selecting the remaining regions as candidates for positioning marks for cutting, and a middle point calculating device for calculating a middle point of the positioning marks for cutting on the basis of the candidates for positioning marks for cutting obtained by the characteristic extractor. |
