Summary:PURPOSE:To contrive the easiness of a position control, and the relaxation of assembling accuracy, by lengthening a bit of area identification information longer than a bit of recording information along a boundary area. CONSTITUTION:The length of a bit of identification information 32 on a band 14 is set as the double or more of the length of a bit of recording information 15, and is set as the length remarkably longer than the visual field in a subscan direction of a CCD consisting of a photoelectric transducer 31. When a required band 14 is detected, a moving body 21, and an optical system 26 is driven firstly, and the bit of identification information 32 at one end of the band 14 is detected. At such a time, the positioning of the moving body 21, and the optical system 26 can be easily performed because a bar code consisting of the bit of identification information 32 is longer than the subscan direction of the photoelectric transducer 31.
