  • Patent number: 8029085
    Abstract: A transport mechanism transports a medium in a transport direction based on a target transport amount and has a first roller provided on an upstream side in the transport direction and a second roller provided on a downstream side in the transport direction. Correction values are calculated based on an interval between the lines in the transport direction. The transport mechanism is controlled based on a corrected target transport amount after correcting the target transport amount based on the correction values. Lines are formed by ejecting ink from a first nozzle when the first roller is in contact with the medium, and ejecting ink from a second nozzle on a downstream side from the first nozzle in the transport direction when the first roller is not in contact with the medium and the second roller is in contact with the medium.

  • Publication number: 20110182411
    Abstract: A particle beam treatment apparatus and an irradiation nozzle apparatus achieve a beam with a small diameter by a beam scanning irradiation method, and ensure a space for installation of a beam transport chamber in the irradiation nozzle apparatus. An X-ray tube is located outside the scanning type irradiation nozzle apparatus that includes scanning magnets, while an X-ray tube is located in an irradiation nozzle apparatus in a conventional structure. An X-ray detector is located inside the irradiation nozzle apparatus. The thickness of the X-ray detector in the direction of a beam axis is smaller and the structure thereof is simpler than that of the X-ray tube. This makes it possible to ensure the space for installation of the beam transport chamber in the irradiation nozzle apparatus and to increase the length of the beam transport chamber that is included in the irradiation nozzle apparatus.
