  • Patent number: 4975740
    Abstract: When documents fed by an automatic document feeder are subjected to the first copying operation, the documents are counted one by one. Alternately, the total number of documents are calculated by dividing the number of copy paper sheets sent to an intermediate tray, by the preset number of copies. Page entry is made in the copy paper sheets taken out from the intermediate tray, based on the total number of documents thus obtained. The total number of documents may be automatically counted. Accordingly, even though the documents are successively fed, starting from the last-page document, page entry may be made. The operator is not required to manually count the total number of documents.

  • Patent number: 4785183
    Abstract: A radiation image information reading method includes scanning a stimulating ray on a radiation image converting panel surface to obtain radiation image information stored on the radiation image converting panel, the scanning step including performing scanning of the stimulating ray while repeating successively irradiation and stopping thereof. In this manner, the noise caused by fluorescent afterflow, stimulation afterglow, stray light from outside of the apparatus or a laser beam, etc., can be removed simply and correctly. A visible image which is correct with good reproducibility corresponding to the real image, and also good in sharpness, can be obtained, whereby diagnosis with high reliability by means of a radiation image is rendered possible. In one embodiment, only image signals detected during periods of irradiation by the stimulating ray are read.
