  • Patent number: 7997320
    Abstract: A sheet cutter cuts an adhesion sheet and includes a pair of blades including a first blade including a blade edge and a second blade opposing the first blade and including a blade edge. The pair of blades cuts a border of the adhesion sheet. The adhesion sheet is formed by adhering a first sheet, at least a part of which is transparent and bears a mirror image, to a non-transparent second sheet including an adhesive layer, to oppose the mirror image on the first sheet against the adhesive layer of the second sheet.

  • Patent number: 7883089
    Abstract: In an image forming apparatus including an image forming unit that forms an image on a recording medium conveyed from a sheet feeding unit to obtain an image with photographic quality, at least a part of the recording medium has a transparent portion. When an image obtained by reversing an original image is transferred onto the transparent part, sheet-delivery rollers are operable in a direction in which a pressure onto the recording medium is reduced immediately after fixing of the image.

  • Publication number: 20080236736
    Abstract: A recording medium is conveyed through a conveyer path. A recording-medium selecting unit selects either one of a non-transparent recording medium and a transparent recording medium, and conveys a selected recording medium to the conveyer path. An image selecting unit selects an image to be formed on the recording medium from among an original image and a reversed image obtained by reversing the original image. A control unit controls, based on a control signal, the recording-medium selecting unit and the image selecting unit.
