摘要： A photoreceptor for an image formation apparatus has a photosensitive layer of a multi-layer structure each having the characteristic of increasing its electrical resistance at a different rate upon expose to light. An image-carrying beam of reflected light from an original to be copied is made incident on the photoreceptor to form a resistance image. An electrostatic latent image is formed therefrom either on the photoreceptor itself or on a transfer medium placed in contact therewith and a visible toner image is formed by applying toner on such an electrostatic image but the resistance image on the photoreceptor remains undisturbed during such image transfer processes. Thus, a plurality of copies of a single original can be produced without exposing the photoreceptor to reflected light therefrom for each copy to be printed.

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： 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.

摘要： An image forming apparatus is arranged so as to include an optical head unit constituted of exposing device and information reading device, one cylindrical white light source which is commonly used as a light source for the above both devices, liquid crystal shutter arrays for individually opening and closing optical paths of the light source in direction of a photoreceptor, and to control open/close operation of an exposure shutter array according to an image signal and to control the shutter arrays such that when the exposing device operates, the information reading shutter array closes and that when the information reading device operates, the exposure shutter array closes. As a result, in an arrangement which is carried out a simultaneous charge-expose-development process and has exposing function and information reading function, it is possible to sufficiently miniaturize an apparatus. Moreover, since the liquid crystal shutter array is used, open/close operation of the optical paths from the cylindrical white light source to the photoreceptor can be easily and securely control.
