摘要:
A line sensor for color reading comprises a plurality of line sensors, each having photosensors arranged one-dimensionally, for the number of the color signals to be separated arranged in parallel with each other on one and the same substrate; and a color filter for color signal separation directly disposed on the light-receiving portion of each of said line sensors. The parallel line sensors may be disposed so as to be non-coplanar, e.g., by provision of insulating layers at least on wiring sections of the first and second line sensors, the second and third line sensors being disposed on the first and second insulating layers, respectively.

A color photosensor which includes a plurality of closely arranged sensor units. Each sensor includes a color filter provided at a position corresponding to that of a photoreceptor. The color filter comprises at least one of coloring matter layers selected from the following groups (A), (B) and (C):(A) A red coloring matter layer including, as a main component, perylenetetracarboxylic acid derivatives selected from the following structural formulas (I) and (II): ##STR1## where R.sub.1 denotes hydrogen, an alkyl group or an allyl group; (B) a green coloring matter layer including, as a main component, phthalocyanine coloring matter, a combination of phthalocyanine coloring matter and isoindolenone coloring matter, or a combination of phthalocyanine coloring matter and authraquinone coloring matter; and(C) a blue coloring matter layer including, as a main component, phthalocyanine coloring matter, or a combination of phthalocyanine coloring matter and quinacridon coloring matter.
摘要:
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 .ANG.; 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.

A photosensor comprising a photoconductive layer provided on a substrate. The layer contains amorphous silicon. At least a portion of the layer has a refractive index varying continuously through the thickness of the layer. The refractive index of the layer is 3.2 or less at a wavelength of 6,328 .ANG. in the vicinity of the surface of the substrate. A pair of electrodes are provided in electrical contact with the photoconductive layer. A photoreceptor is also provided, part of which is constituted by the spacing between the electrodes of the pair.
