  • Publication number: 20120000078
    Abstract: An object of the invention is to achieve the practicable use of a pair of barber scissors having a sliding-cutting function. In the barber scissors configured of blade bodies each including a cutting blade and handle, a gear accommodation hole is formed at a pivotal joint intersection of one blade body; a rack is formed on the inner-surface of the gear accommodation hole; and a guide groove is formed in the outer-surface of the blade body. In the pivotal joint shaft position of the other blade body, a pinion having arc-shaped teeth to engage with the rack is mounted to rotate together with the blade body; a guide member having a projection to fit into the guide grove is disposed striding the outer-surface of the gear accommodation hole; and a nut is screwed and mounted on the pivotal joint screw shaft protruding from a shaft hole of the guide member.

  • Publication number: 20100171972
    Abstract: Multi-valued image data stored in an input image buffer are read out for each time of scans, and the color space conversion and image distribution are performed to read multi-valued image data. The binarized result is sent to the print buffer and at the same time, is accumulated as the print information to execute processing of reflecting it to the image distribution processing of the next pass. It is possible to appropriately restrict the density fluctuation due to the print position shift between planes without providing pixels where dots are overlapped and printed more than necessary. With this, by accumulating the multi-valued image data at the stage of RGB in the input image buffer to read out data stored in input image buffer for executing processing, a capacity required for input image buffer does not change even if the number of the ink colors provided on the printing apparatus increases.

  • Publication number: 20100026746
    Abstract: In a multipass printing that performs a plurality of printing scans over a unit area of a print medium by using a leading head and a follower head, the multivalued image data for the leading head is distributed according to the print volume information for up to the preceding printing scan. Then, the multivalued image data for the leading head is subjected to the grayscale level reduction operation to generate binary data. Based on the binary data, the print volume information is updated, after which the multivalued image data for the follower head is distributed according to the print volume information. This causes a plurality of printing scans or a plurality of print heads, that print the same unit area, to have a correlation among them, with the result that dots on a plurality of planes when overlapped have an excellent scattering characteristic.
