Abstract: An image forming apparatus is disclosed for providing accurate shading corrections. The apparatus includes an illumination source for illuminating an image, and a photoelectric converter that receives reflected light from the image and photoelectrically converting the reflected light. The output signal from the photoelectric converter is amplified and converted to a digital signal. The digital signal is then subjected to shading correction. A controller is provided for ensuring that white reference data for a first sheet of copy is fetched from a stable region of the illumination source during shading correction. The white reference data is subsequently used when forming an image for a first sheet of copy.

Abstract: An image reading device capable of preventing, by increasing the quantity of light at the center or bound portion of a spread book document, the quantity of light from becoming short and preventing density from becoming irregular due to the deviation of a focus. At and around the center of a spread book document where the document is bound, the quantity of light for illumination or the amplification gain of image data read from the document is increased. A plurality of fluorescent lamps illuminate the surface of the document at the upstream side and downstream side with respect to an intended scanning direction. When the edge of the document is to be detected, only one of the lamps is turned on to enhance the stripe pattern representative of the stepped edge portion of the document.

Abstract: An image reading device has two different modes for controlling the switchover of a motor drive pattern. Either one of the two modes is selected in accordance with various drive conditions including a drive speed. In one mode, in response to every drive pattern switching pulse, pattern data are output by software processing while a position signal is referenced. In the other mode, a macro transfer function is used to output the pattern data by DMA (Direct Memory Access) while the position signal is referenced at every repetition cycle of the drive patterns. The device is capable of reading an image at high speed by switching the drive pattern rapidly, thereby obviating irregularity in a reference position for reading an image.

Abstract: In an image forming apparatus capable of reading a book document while turning over pages of the book, image data representative of two spread pages of a book document are stored in a frame memory. Among the image data, image data matching the front of a sheet are read out of the frame memory first and then output on the front of a fresh sheet. Then, an image is formed on the rear of a sheet refed from a duplex copy tray or refeed tray. Alternatively, an arrangement may be made such that, among two pages of image data, the image data read last are out of the frame memory first and then output on the front of a fresh sheet, and then an image is formed on the rear of a sheet refed from the refeed tray.

Abstract: A finisher operable with an image forming apparatus for discharging paper sheets coming out of the apparatus and each carrying an image thereon to a plurality of bins while sorting the paper sheets and, if desired, packaging the paper sheets in an envelope. When a pack mode is selected, the size of paper sheets and the sizes of envelopes which are to be fed from a paper cassette or a tray each are sensed by size sensors. Envelopes sizes capable of accommodating the paper sheets of the sensed size are determined and compared with the sensed envelope sizes. Among the determined envelope sizes, the envelope size capable of accommodating the paper sheets of the size sensed by the size sensor in a desired number inputted. When the desired number is too great to be packaged in the envelope, such an occurrence is displayed and/or the pack mode is cancelled.
