  • Patent number: 9061856
    Abstract: In the control of a cutting mechanism of a sheet processing apparatus, when rear end cut region of a sheet is finely cut and divided into predetermined fine-cutting unit length, if sheet conveying direction length of rearmost end divided region is equal to or more than minimum reference length corresponding to the distance between cutting position of the cutting mechanism and nipping position of a pair of first conveying rollers and is less than maximum reference length in which predetermined fine-cutting unit length is added to minimum reference length, upper and lower blades of the cutting mechanism are held opened immediately after the downstream edge of rearmost end divided region is cut and the pair of first conveying rollers are driven at limited conveying speed lower than normal conveying speed.

  • Publication number: 20070215788
    Abstract: An exposure apparatus of the invention has a dot array head of a fluorescent type having light-emitting units UR, UG, UB of three primary colors. A controller E is provided with an area dividing unit that divides the dot array head into an image area, in which control of light emission based on image data is performed, and the other non-image areas. In addition, a dot array head control unit in the controller E comprises a light emission control unit that controls the dot array head such that light is emitted based on the image data in the image area and dummy light emission takes place in the non-image area when exposing photographic paper. The dummy light emission data is created by the dummy light emission data creating unit, based on image data corresponding to a single dot D1 adjacent to a boundary of the image area and the non-image area.

  • Patent number: 6760055
    Abstract: A photographic processing apparatus according to the present invention exposes photographic papers using a laser beam modulated based on image data and includes a laser beam emitting device. A changeover part changes the level of a driving signal to any one of a plurality of discrete levels according to a coloring characteristic of the photographic paper. The level of the driving signal determines the intensity of the laser beam outputted from the laser beam emitting device in a plurality of levels (for example, three levels consisting of a high level, a middle level and a low level). A filter is also provided to reduce the intensity of the laser beam outputted from the laser beam emitting device.
