Abstract: There is a photosensor comprising: a photoconductive layer containing amorphous silicon provided on a substrate in which this photoconductive layer consists of laminated films of two or more layers having different refractive indexes and the refractive index of the lowest layer of the laminated films is not larger than 3.2 for the incident light of a wavelength of 6328 ANGSTROM ; a pair of electrodes provided in electrical contact with the photoconductive layer; and a photo sensing section. A long size image sensor unit is constituted by a plurality of such photosensors arranged like an array, a matrix drive circuit to matrix-drive each photosensor, and a light source such as light emitting diodes or a fluorescent lamp to illuminate an original to be read. With this image sensor unit, it is possible to provide a low-cost image reading apparatus which can read an image on the original at a high speed in which: the uniformity of the characteristic of each photosensor is improved; a variation in signal between the bits is reduced; a correction circuit for such a variation is unnecessary; and the peel-off of the photoconductive layer does not occur. A method of manufacturing such photosensors is also disclosed.

Abstract: A photosensor array for use with an image processing apparatus has a plurality of photosensors disposed in an array. Each photosensor includes a substrate, a photoconductive layer formed on the substrate and made of an amorphous silicon, and a pair of electrodes disposed on a surface of the photoconductive layer, the electrodes being spaced apart from each other by a certain distance partially defining a light receiving region of the photosensor. In the phososensor array, the photoconductive layer is constructed as of two or more laminated layers, and the lower layer positioned nearer to the substrate has a low content of oxygen.

Abstract: A linear matrix having heat printing heads or photosensors is disclosed. At least some of the electrodes, a multi-layer wiring region and through-hole regions which connect the multi-layer wiring region to the electrodes are arranged such that they form a pattern which is symmetrical in the longitudinal direction of the matrix.
