APPRESSED TYPE IMAGE SENSOR

PURPOSE:To enable one appressed type image sensor to read different colors separately by arranging two arrays of photoelectric converting elements a side of transparent window arrays, and providing each converting element with a blocking electrode. CONSTITUTION:A light-shielding layer 26 is provided on a transparent substrate 22 except transparent window arays 23, 24 and 25. Photoelectric converting element arrays 27 and 28 are provided among the transparent window arrays. Each photoelectric converting element is provided with a blocking electrode, and a lead electrode is led out. They are covered with a transparent protective layer 31. An original P is placed on the transparent protective layer 31 and lighted succeessively by light sources 41, 42 and 43 for red, green and blue from the transparent substrate side. According to lighting states of the light sources, either of the photoelectric converting element arrays 27 and 28 is blocked with blocking electrodes to obtain pieces of color information on red, green and blue successively. Thus, one image sensor reads those colors separately.
