Abstract: A two-dimensional image read-out device comprising a photoconducting layer, a plurality of X stripe electrodes applied on one surface of the photoconducting layer and arranged parallel with each other, and a plurality of Y electrodes applied on the other surface of the photoconducting layer and arranged parallel with each other in a direction perpendicular to the X electrodes. Both the X and Y electrodes are made of electrically conductive material, and the X or Y electrodes through which light from an image enters are made of transparent or translucent material. The light-entering side of the two-dimensional image read-out device is covered with an opaque material which allows the passage of light only through the picture elements which are formed at the intersections of the X and Y electrodes.

Abstract: A two-dimensional image read-out device comprises an insulating substrate, a plurality of Y-line electrodes formed on the insulating substrate and arranged parallel with each other, a plurality of X-line electrodes formed over the insulating substrate and arranged parallel with each other in a direction perpendicular to the Y-line electrodes, a photoconductive layer interposed between the Y-line and the X-line electrodes, gate electrodes for selecting a pair of the Y-line and the X-line electrodes, and three scanning circuits for selecting some of the Y-line electrodes, and some of the X-line electrodes, and at least one of the gate electrodes, respectively.

Abstract: A two-dimensional image sensor includes a two-dimensional photoconductive layer. A flat common electrode is formed on one major surface of the two-dimensional photoconductive layer. A pin electrode array having a plurality of pin electrodes aligned in a first direction is disposed above a second major surface of the two-dimensional photoconductive layer. An optical fiber lens array is fixed to the pin electrode array in order to apply optical image onto the second major surface of the two-dimensional photoconductive layer at a same time when a high voltage is applied by the pin electrodes. A shift means is connected to the pin electrode array to shift the pin electrode array and the optical fiber lens array in a second direction which is perpendicular to the first direction. Electric current is obtained at the flat common electrode, which represents the optical image applied by the optical fiber lens array.

Abstract: The present disclosure is directed to a two-dimensional image readout device. The device includes a sensor device consisted of an insulating substrate, a plurality of parallel Y electrodes of conductor, a plurality of X electrodes disposed in a direction normal to the Y electrodes with a spacing therebetween and a photoconductive layer interposed in the spacing between the Y and X electrodes, at least one of the Y and X electrodes being made of transparent material. There are further provided an optical system for leading to a surface of the sensor device an image to be read out, a control circuit for scanning the photoconductive layer in association with guide operation for leading the image to the surface of the sensor device via the optical system while the electrodes are switched.
