PPROBLEM TO BE SOLVED: To provide a method and a device that can precisely image-pick up a plurality of reference portions arranged in a very small space in a short time without generating a mutual interference in a plurality of camera means, and can detect the coordinates of the each reference portion and to provide a method of positioning a print circuit board. PSOLUTION: The detection method and the detector are provided with an optical guide means 10 wherein images of the at least two reference portions are divided into a plurality of images corresponding to the every reference portion by an optical splitting means, wherein images of the at least two reference portions 31a incident into incident ports 11a are divided into a plurality of images corresponding to the every reference portion by the optical splitting means, and wherein the plurality of images are guided respectively to emission ports 11b, and the camera means 20 faced respectively to the plurality of emission ports 11b. A plurality of image-picked-up data by the plurality of camera means 20 are image-processed to detect the coordinates of the respective reference portions 31a. PCOPYRIGHT: (C)2003,JPO
