Abstract

PURPOSE:To simplify a configuration and to reduce the size of an image sensor unit by forming a signal processor for processing the output of a photoelectric converter on a transparent substrate by employing a thin film transistor (TFT) on the same substrate. CONSTITUTION:A plurality of photoelectric converters arranged in a row, TFTs for driving them, and a sensor 22, such as a shift register formed of the TFT2 are provided on a transparent substrate 21. A current/voltage converter 11, an integrator 12, a peak holding circuit 13, and a A/D converter 14 for forming a signal processor 23 formed of TFT for processing the output of the sensor 22 are provided simultaneously on the substrate 21 near the sensor 22. Accordingly, the connecting length thereamong is shortened as compared with the case that the signal processor and the sensor are individually formed and connected by wirings in structure to improve its S/N and to simplify the configuration and to reduce its size.
