  • Patent number: 8506433
    Abstract: A continuously variable transmission configured to transmit a rotational driving force of one pulley to another pulley by a driving-force transmitting means wound between the two pulleys, wherein each of the two pulleys is configured to vary a groove width thereof, the continuously variable transmission including: an engagement-receiving portion provided to the driving-force transmitting means, in a side of the driving-force transmitting means on which the driving-force transmitting means is wound on the pulleys; and a movable engaging portion provided to a shaft portion of at least one of the two pulleys, wherein the movable engaging portion is movable in a radial direction of the shaft portion to protrude from and escape into the shaft portion, wherein the movable engaging portion is configured to protrude from the shaft portion so as to engage with the engagement-receiving portion at least one of when a pulley-ratio region is in a setting for highest speed and when the pulley-ratio region is in a setting f

  • Patent number: 6507415
    Abstract: An image processing device includes a scanner, which reads a plurality of images and inputs them as multivalue digital image data; a matching data producing section which, based on the inputted multivalue image data, produces matching data for joining the respective inputted images; a post-processing section, which binarizes the image data of each image inputted by the scanner; a joining section, which synthesizes the respective inputted images into a single image by joining the binary data produced by the post-processing section, which corresponds to the image data of the respective inputted images, on the basis of the matching data produced by the matching data producing section; and a printer for outputting the image joined by the joining section. Thus an image processing device can be provided which is capable of joining any type of image, whether from written characters, halftone dot, or photographic originals, and of performing this joining processing at high speed.
