Abstract: A medium thickness detecting apparatus detects the thickness of a recording medium. A displacement section is disposed in a transport path through which a recording medium passes. When the recording medium passes the displacement section, the displacement section displaces in a direction substantially normal to the surface of a recording medium. An amplifying section amplifies a displacement of the displacement section by a predetermined factor. A thickness determining section outputs a signal representative of an amplified value of the displacement. The displacement section may be one of two rollers between which the recording medium passes, and displaces upward when the recording medium passes between the two rollers. Alternatively, the displacement section my be positioned to sit on a stage provided in the transport path such that the displacement section is pushed away from the stage when the recording medium passes between the displacement section and the surface.

Abstract: An image sensor uses an image reading element formed by integrating pixels for converting image information to an electric signal. In each of the pixels, a common electrode common to all the pixels and an individual electrode corresponding to each of the pixels are disposed through at least an organic photoconductive layer. A crosstalk capacitance of each of the pixels is equal to or smaller than 35% of a sum of an electric capacitance between individual electrodes and an output capacitance of the individual electrode. A blocking layer may be disposed between the common and individual electrodes. Each of the pixels may be constructed such that the individual electrode is arranged on a supporting body, and a blocking layer and the photoconductive layer are formed on the individual electrode, and the common electrode is arranged on the blocking and photoconductive layers.
