  • Publication number: 20150367580
    Abstract: A three-dimensional shaping apparatus according to the present invention includes a shaping stage, an ascending/descending unit, a shaping head, a light sensor, and a light source. The shaping stage is configured to carry a shaped object. The ascending/descending unit is movable at least along a vertical direction with respect to the shaping stage. The shaping head is mounted on the ascending/descending unit. The light source is configured to emit light directed toward the light sensor. One of either the light sensor or the light source is mounted movable in accordance with movement of the ascending/descending unit, while the other of either the light sensor or the light source is disposed fixedly relative to the shaping stage.

  • Patent number: 7095433
    Abstract: There is disclosed an optical printer for printing a grayscale image on a self-developing type photo film unit based on image data. A printing head of the optical printer is provided with a plurality of light emitting elements arranged in a line along a main scan direction whose lighting time lengths are controlled for each pixel in accordance with a tonal level of that pixel. The printing head is shifted relative to the photo film unit in a sub scan direction perpendicular to the main scan direction, to print the image line by line. During each printing cycle of one line, drive voltage applied to the respective light emitting elements are raised with time from an initial value according a predetermined characteristic curve, to increase luminance of the respective light emitting elements as the lighting time for each pixel elapses.

  • Patent number: 5103242
    Abstract: A print is postprocessed by using a thermal transfer type of video printer in which an array of heater elements is heated in response to a video signal representing an image to transfer a dye from a dye sheet onto an image-receiving medium to record the image on the medium. A flat postprocessing sheet is prepared which has a primary surface worked to form a desired postprocessing surface contour thereon. The medium on which the dye is transferred is set in the video printer with the primary surface of the postprocessing sheet being brought into contact with the surface of the medium onto which the dye is transferred. The video printer is enabled to press the set postprocessing sheet together with the medium carried thereon via the dye sheet onto the medium by the heater array. The heater array is heated to a predetermined temperature to achieve a postprocessing on the medium. The predetermined temperature exceeds a softening point of a material of an image-receiving layer of the medium.
