Abstract

PURPOSE:To read in large read-in object with small photodetector with excellent manner, by alternately arranging the illumination fiber and read-in fiber at the read- in side in one line, and opposing light source and photodetector for other end of illumination and read-in fibers. CONSTITUTION:To the original 1, illumination fiber system 2 and read-in fiber system 4 are alternately arranged in one line, and the light source 3 for illumination is located to the end of illumination fiber system 2, and photodetector 5 is located at the end of fiber system 4. Further, since the diameter of the fiber system 4 is greater, the pitch of photodetectors is made coarse toward primary arrangement, and when the number of photodetector of primary dimension arrangement is n or less, a plurality of primary dimension arrangement photodetectors are used, allowing to read out greater original 1 with less photodetectors.
