Abstract: Data, on which one page of original image data should be image-processed, indicates a first block image (G1) constructed of continuous nullnnull lines of the original image, commenced from a top line thereof; and a second block image (G2) through an M-th block image (GM). Each of the second to M-th block images is comprised of continuous nullnnull lines of the original image, and overlapped portions for nulldnull lines are present between the first to (Mnull1)-th block images (G1 to GMnull1) and the second to M-th block images (G2 to GM), respectively. With respect to each of the block images, (nnullW) pieces of pixel data indicative of this block image are supplied to an image processing circuit in both a column positional order and a line positional order, while the column position owns a top priority.

Abstract: A printing apparatus capable of printing a mirror image without increasing the apparatus size. Print data for one band image is stored into an image memory 7 in accordance with an address (in an ascending order) generated by an address counter 103. After storing the print data for one scanning by a print head 101 has been completed in the image memory 7, the print data is read out in accordance with an address (in an descending order) generated by an address counter 104 from the image memory 7, and outputted to the print head 101. At this time, since print data which has previously been used for printing is used no longer, the address counter 103 is set to generate an address in the descending order, and storing of the next print data is made in parallel to the printing. When the printing based on the print data in one scanning has been completed, an address counter 106 is set to generate an address in the ascending order for the next image printing. In this manner, mirror-image printing is performed with changing over a counter update direction between ascending/descending orders.

Abstract: In an image forming apparatus having two-face copy mode, an image reader can read a document image placed on a platen along a subscan scan direction and along a direction reverse to the subscan direction. The image reader includes an image sensor for reading a document image along a main scan direction and along a direction reverse to the main scan direction. In the normal image mode and in the reverse image mode, a normal image and a reverse image of a document are formed by controlling the reading direction and the subscan direction. When a stapler is used to staple a plurality of copy papers, but at positions in the papers which are not appropriate to turn over them if normal images are formed on the papers, the reverse image mode is set for forming a normal image of the document. Further, when a back face is printed in two-face copy mode, it is decided if the back face is placed on the platen so that the image in the back face is reproduced as a reversed image to the image in the front page according to document direction (portrait document or a landscape document), a position of margin, and a direction of the document with respect to document feed direction. The scan mode is changed when it is decided that the document is placed on the platen so that the image in the back face is reproduced as a reversed image to the image in the front page.

Abstract: A method and an apparatus are described for digitization of an image and for transmission to a host device of the digitized image via a buffer memory having a signal storage capacity that is lower than the data content of said digitized image. Different portions of the image are stored in the memory during successive separated periods of time. To this end the image is repeatedly scanned by means of radiation emitted by radiation projecting means that are transported at a constant scanning speed from a boundary outside the image beyond the image portion to be stored.

Abstract: An image scanning device has first and second image scanning units to scan an image on the front and rear surfaces of a document to sequentially output image data on a line-by-line basis. A determining unit determines whether or not the number of lines of the front image is greater than or equal to a predetermined number, and whether or not the number of lines of the rear image is greater than or equal to the predetermined number. A processing unit reads out the front and rear image data on a line-by-line basis for the predetermined number of lines and performs image-processing on the readout data if the number of lines of the front image data is greater than or equal to the predetermined number and performs image-processing on the readout data if the number of lines of the rear image data is greater than or equal to the predetermined number.
