  • Patent number: 5961226
    Abstract: A printing apparatus capable of feeding standard and non-standard sheets so that image data can be printed on various types of sheets with the need for increasing the number of internal components. One embodiment for achieving this includes a sheet setting unit that permits selection of one of a plurality of predefined sheets, a sheet width sensor unit that senses whether sheets in a sheet supply member meet a predefined width, and a controller coupled to the sheet setting unit and the sheet sensor unit. The controller is responsive to either the selected one of the plurality of predefined sheets or user input of dimensional data of the sheets in the supply member. Based upon the set sheet type or input dimensional data, the controller then adjusts the magnification of the image to be printed and prints the image on the sheets.

  • Patent number: 5905935
    Abstract: A finisher connected to a digital copying machine includes a folding device for folding output paper into Z shape, a binding device for binding a sheaf of the papers into a preset size, and a control unit that determines whether image property will be affected or not when the images are printed on the A4 size paper, and print on the A3 size paper and fold the A3 paper into the Z-shape if it is determined that the property will be affected. Therefore, even if the original document size is different from the exclusive use cover size, the finisher provides good legibility of the characters printing its output automatically on paper of a proper size matching the exclusive use cover. In other words, good-looking bookbinding can be easily accomplished for documents of varying sizes without manually adjusting enlargement/reduction factors.

  • Patent number: 5790921
    Abstract: When zoom keys for changing a magnification by a predetermined unit each time, not only setting of a fixed magnification is bothersome, but also setting a magnification in the vicinity of the fixed magnification is very troublesome. A zoom up key and a zoom down key for changing a magnification by a predetermined unit, e.g., 1%, each time to set to a desired magnification are provided. By operating either one of the keys, a set magnification is zoomed up or down, while displaying that condition in an LCD display which serves as a display portion. While the set magnification shifts, when the set magnification becomes a fixed magnification or a magnification close to the same, a sub message as well is displayed which indicates an optimal combination of original and paper sizes with which processing at that fixed magnification is possible. Referring to the displayed sub message, the desired magnification is set by operating the zoom up key or the zoom down key.
