    摘要: A photosensor having an electrically insulating, translucent substrate; an opaque conductive layer formed on the substrate; and insulating layer formed on the conductive layer, and a semiconductive layer formed on the insulating layer for receiving light and providing a current corresponding thereto. A pair of electrodes are formed in contact with the semiconductor layer and define a light receiving window therebetween. The electrodes are formed so as to not substantially overlap the conductive layer. The conductive layer is supplied with a bias voltage corresponding to a polarity and an amount of carriers defining the current of the semiconductor layer and a voltage Va of a small absolute value during a non-reading period of the photosensor.

    摘要: An image reading device has photo-sensor units arranged in the form of an array constituting a line sensor. Each sensor unit includes a light-shielding layer formed on a light-transmitting substrate, an insulating layer formed on the light-shielding layer, a semiconductor layer disposed on the insulating layer, and a pair of upper electrodes provided on the semiconductor layer and spaced from each other. The space between the upper electrodes constitutes a light-receiving window through which the semiconductor layer receives light applied from the reverse side of the substrate onto the surface of an image-carrying original and reflected by the original. Thus, the semiconductor layer produces an electric signal representing the read image. The light-shielding layer is made of an electrically conductive material such as a metal. A voltage application circuit is provided for applying to the light-shielding electrode a voltage of a level which is lower than the levels of voltages applied to the pair of upper electrodes. The level of the voltage may be varied along the length of the array of the photo-sensor units.
