Noritaka Nakashima has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9908341
    Abstract: The present invention intends to provide a printing apparatus that can lessen a reduction in ejection performance caused by thickening, solidification, or the like of print liquid in an ejection port of a printing unit even in the case of stopping a print operation by the printing unit to perform a post-process on a print medium. The printing apparatus includes a post-processing part configured to, in a state of stopping the print operation by the printing unit, perform the post-process on a printed print medium as well as including an open/close unit configured to selectively perform a closing operation or an opening operation of the ejection port provided in the printing unit. Further, when the print medium is stopped in the post-processing part, the open/close unit is controlled so as to bring the ejection port into a close state.

  • Patent number: 8944544
    Abstract: The present invention provides a printing apparatus and a printing method which, even if print media of different sizes are printed, can print images in well-balanced, optimum layouts according to the size of each of the print media. Thus, the printing apparatus according to the present invention has leading end detector which detects a leading end of a print medium and trailing end detector which detects a trailing end of the print medium. The printing apparatus further has print control unit which prints images based on a first print data for which a print start position is determined on the basis of the leading end detected by the leading end detector and second print data for which a print start position is determined on the basis of the trailing end detected by the trailing end detector.

  • Publication number: 20080291226
    Abstract: For use when the recordable area of a recording medium is smaller than recording data, there is provided a recording device that can determine the priority of divided areas and preferentially record a high-priority area. The recording device assigns priority to each of the recording areas of a whole image on one page and, if it is determined that the whole image does not fit on the recording medium, performs at least one of rearranging the recording position of a high-priority area, changing the recording size of a low-priority area, and discarding a part of recording data of the low-priority area based on the priority of the recording areas to prevent any part of the image of the high-priority area from being lost.
