    摘要： An electrophotographic copying machine includes a combined developing-cleaning magnetic brush element. When the copy sheet is smaller than half the size of a photosensitive drum surface, two sheets of copy are obtained by three revolutions of the photosensitive drum in a multi-copy mode. During the first revolution of the photosensitive drum, the combined developing-cleaning magnetic brush element conducts the developing operation onto a first half section of the photosensitive drum and conducts the cleaning operation onto a second half section of the photosensitive drum. During the second revolution of the photosensitive drum, the first half section is cleaned and the second half section is developed. During the third revolution of the photosensitive drum, the first and second half sections are cleaned by the combined developing-cleaning magnetic brush element.

    摘要： A document feeding device for feeding documents to a document scanning section where the image of the document is scanned. The document feeding device has first trasnport rollers for feeding each document to the scanning section, discharge rollers for discharging from the scanning section the document thus supplied, a reversing transport path for passing and turning over the document sent from the discharge rollers, and second transport rollers for feeding the document that has been turned over through the reversing transport path to the document reading section. The reversing transport path is designed to change the length of the document transport path depending on the size of the document. With the arrangement, reversing operation and scanning operation of the documents can be performed effectively. Further, without increasing the momentary transporting speed of the document transport mechanism, this arrangement makes it possible to feed documents at comparatively high speed from an entire apparatus standpoint.

    摘要： A digital image forming apparatus includes a CCD optical unit and an information editing section. The CCD optical unit inputs image information to an image control unit (ICU) upon an instruction to start image formation input through an operation panel. The information editing section inputs the image information to the ICU upon an instruction to start image formation input by a keyboard. The ICU stores the image information input from the information editing section page by page depending on an image processing mode specified through the operation panel and the keyboard, and successively performs image processing on the stored image information page by gage. With this arrangement, various image editing functions of a digital copying machine is effectively used for image information input from the information editing section.

    摘要： The present invention is made to reduce the effect of variation of pulses for driving a printer when recording image data and to improve the gray level representation of picture images to be printed. Data incoming through an image reading device are quantized and processed two pixels at a time by a gray level image processing circuit. The two-pixels' data are first discriminated by an edge discriminator to determine whether they represent an edge portion within the image or not. An object image, on which an operation for inter-pixel spacing shall be conducted, is selected according to the discrimination result. The arithmetic and logic portion performs the above-mentioned operation by two pixels at a time if the data correspond to a non-edge portion and performs correction for enhancement if the data correspond to an edge. This may eliminate the effect of dot displacement due to variation of drive pulses of a printer and improve the quality, in particular, of a gray level image portion.

    摘要： An X-ray image pickup tube converts a transmitted X-ray image into electric signals. The pickup tube includes a target structure having a fluorescent element, and a translucent conductive film for receiving a high voltage, with a photoconductive film laminated thereupon. The fluorescent element receives transmitted X rays in a two-dimensional distribution, and converts them into visible rays in a two-dimensional distribution. The translucnet conductive film is optically coupled to a surface of the fluorescent element opposite from an X-ray incident surface thereof. The photoconductive film includes an amorphors semiconductor layer which converts the visible rays transmitted in a two-dimensional distribution through the translucent conductive film, into electric charges in a two-dimensional distribution, and which multiplies the electric charges in the two-dimensional distribution based on electric fields formed by the high voltage applied to the translucent conductive film. The pickup tube also has a signal reading device in the form of an electron gun or switching elements for scanning a surface of the photoconductive film, as electric signals, a two-dimensional electric potential distribution occurring on the photoconductive film.
