Abstract: An image processing apparatus including an input device for inputting image data, a storage device for storing image data from the input device, and a controlling device. The controlling device controls the parallel operations of a) writing image data into the storage device, and 2) reading image data from the storage device. Therefore, fast output is possible. Moreover, in a book copying mode, when copying two facing-pages with a scanner, copies of the first of two facing-pages are printed while the second of the two facing pages is scanned. As a result, this apparatus and the corresponding method enable a document to be changed easily and prevent extended holding times by an operator when using book copy mode.

Abstract: An image forming apparatus for detecting and eliminating avoidable image reading operations includes a scanner for reading an original document, a memory for storing read image data, a printer for forming an image in accordance with the image data read from the memory, a ten-key pad for inputting instructions specifying a total number of sets of copies to be made, various functions to be performed by the apparatus for changing how the copying is performed and a sample set command by which the apparatus enters into a sample set command mode wherein one copy of the original document is output as a sample copy, and a controller for determining whether to use the image previously stored in the memory to output the rest of the total number of sets of copies to be made or performing an operation of reading the original document again depending upon types of functions input via the ten-key pad during the sample set command mode.

Abstract: A method controls a display for a copying machine including a device having two-dimensional dot displaying device in which displaying layers for at least two colors of red and green are provided and capable of displaying at least four colors red, green, white, and black by combining the displaying layers. The method is made up of the steps of providing storing device including a memory space which corresponds to a display of the dot displaying device and in which addresses are sequentially assigned. The system then calculates display information of one-dimensional absolute address position information in response to display information in which coordinate information is made into two-dimensional coordinate information. This display information is stored in the storing device, and then supplied to the displaying device so as to be displayed. The display device is primarily a dot type device.

Abstract: An operating panel of a copying apparatus including an operation mode for setting a function selected from a plurality of functions of the copying apparatus. The operating panel includes a display surface provided with a touch panel sensor device. By manipulating the display surface, the function can be designated and the designation can be cancelled. The designated function is deleted from the display surface. Inputs relating to the designated function are made inefficient so that the function becomes inoperative.
