  • Patent number: 5212519
    Abstract: An image forming apparatus comprises an inner memory, first checking means, second checking means, a mode selector, judging means and a portable memory. The portable memory is adapted to be connected to the main body of the apparatus and memorizes a portable memory identification number to identify the same portable memory and a plurality of usable apparatus numbers to represent usable image forming apparatuses which become usable by the connection of the same portable memory. The inner memory memorizes an apparatus identification number to identify the image forming apparatus and a plurality of acceptable portable memory numbers to represent portable memories acceptable for the same image forming apparatus. The first checking means checks if the apparatus identification number coincides with any of the usable apparatus numbers, and the second checking means checks if, the portable identification number coincides with any of the acceptable portable memory numbers.

  • Patent number: 5006891
    Abstract: The invention provides an image forming apparatus capable of performing an ordinary copy mode, whereby the entire surface of a document is scanned by an image reader to copy the entire surface on a copy sheet, and a serial page copy mode, whereby first and second half portions of the document are separately scanned to copy each half portion on a separate copy sheet. In the apparatus, copy sheets of different sizes are fed from a plurality of cassettes each storing a copy sheet of a predetermined size or a manual feed tray. There is provided a memory for memorizing a serial copy sheet size to be fed from the manual feed tray. When the serial page copy mode is selected in the manual feed mode, the image reader is controlled to separately scan the first and second half portions of the document on the basis of the serial copy sheet size.

  • Patent number: 4701044
    Abstract: An image recording system capable of recording a composite image composed of a plurality of partial recording image areas comprises an electrically chargeable image carrier. Image recording area coordinate data is fed into the system to define an area to be recorded and/or image eliminating area coordinate data is fed into the system to define an area to be eliminated. Thereafter, a charge in the charged area of the image carrier is eliminated according to the recording area coordinate area. The same process is carried out for a plurality of desired areas of image data to produce a composite image.
