摘要： A device main body is formed portable, which includes (i) an information writing/erasing section which erases information recorded in a liquid crystal paper and returns the liquid crystal paper into an initialized state in which information recording is possible, and records information previously stored in the device main body into the initialized liquid crystal paper as required, and (ii) a sheet holding section which holds the liquid crystal paper in such a manner that the liquid crystal paper can be transported to an information erasure position and an information recording position in the information writing/erasing section and that the liquid crystal paper is curved at portions thereof other than those at which information recording and erasing is carried out. With this, it is possible to provide an information recording device with improved operability, such as improved portability and capability of easily reading out information at any place.

摘要： A photoreceptor for electrophotography including an electrically conductive substrate, a bottom layer, a photoconductive layer composed mainly of amorphous silicon, and a surface layer, in that order. Both the bottom and surface layers have a greater optical bandgap than said photoconductive layer. A first middle layer is disposed between said bottom layer and said photoconductive layer, and a second middle layer is disposed between said photoconductive layer and said surface layer. Both the first and second middle layers are composed mainly of amorphous silicon and have a concentration of doped atoms which varies from the bottom to the top of the layer.

摘要： An amorphous silicon (a-Si) photoreceptor includes an amorphous silicon (a-Si) photoconductive layer, and a surface layer disposed above the amorphous silicon (a-Si) photoconductive layer. An intermediate layer is disposed between the amorphous-silicon (a-Si) photoconductive layer and the surface layer to ensure the energy level matching. The intermediate layer is made of amorphous silicon (a-Si) doped with nitrogen and boron so as to have the energy difference of less than 0.2 eV between the bottom of the conduction bands of the surface layer and the intermediate layer.

摘要： An image processing apparatus is connected to an image reading apparatus which reads a read area set on a scanner platen in accordance with a size of a document placed on the scanner platen so as to create image data in which an image of the document is shown. The image processing apparatus includes a document detection section and an instruction section. The document detection section creates, based on the image data supplied from the image reading apparatus, document area information indicative of an area where the document is placed on the scanner platen. In a case where the area indicated by the document area information is not completely encompassed by the read area, the instruction section sets a reread area which completely encompasses the area indicated by the document area information and causes the image reading apparatus to read the reread area. In a case where a document which is not completely encompassed by the read area is read, a user can carry out a rereading process more easily than a conventional art.
