  • Patent number: 11104534
    Abstract: A sheet conveyer, including a first guide with a guide surface, a second guide arranged on a side of the guide surface toward one end in a widthwise direction, a first roller arranged upstream in a conveying direction from the second guide to rotate about a first axis extending in parallel with the widthwise direction, a second roller arranged downstream in the conveying direction from the first roller to rotate about a second axis inclined with respect to the widthwise direction, and a third roller arranged downstream in the conveying direction from the second roller at a position on a side of the guide surface toward the other end in the widthwise direction outside a widthwise length of the sheet, is provided. The third roller is configured to rotate about a third axis inclined with respect to the widthwise direction.

  • Patent number: 10730139
    Abstract: This laser irradiation mechanism includes a control unit which has a function allowing the focal point of a laser beam to describe a circle, performs control such that the focal point describes a spiral, and performs control such that the central axis of the spiral moves along a curved surface.

  • Patent number: 9120505
    Abstract: In a vehicle driving assistance device, a steering controlling unit estimates lane lines behind a subject vehicle based on lane lines recognized ahead of the subject vehicle and a running state of the subject vehicle, determines whether or not there is a passing vehicle on an adjacent lane based on the estimated lane lines behind the subject vehicle and a solid substance that is detected behind the subject vehicle by a solid substance detecting unit. If there is a passing vehicle a set distance behind the subject vehicle, the steering controlling unit corrects a steering angle of steering control set based on the lane lines ahead of the subject vehicle toward a direction in which the subject vehicle moves wary from the passing vehicle.

  • Patent number: 8477997
    Abstract: In right and left white road line detection regions on a image, a stereo image recognition device of a white road line recognition device for a vehicle detects a pair of a white road line starting point and a white road line ending point for each of retrieval lines set in the horizontal direction based on the change in the luminance on the retrieval lines, calculates a midpoint Pm between each pair of the white road line starting point and white road line ending point, selects a point group with a smaller dispersion between the point group consisting of the white road line starting points and the point group consisting of midpoints based on a predetermined condition, and calculates a white road line based on the selected point group.

  • Patent number: 8363896
    Abstract: The stereo image recognition device detects a first white road line starting point by luminance change on retrieval lines in a first white road line detection region set on an image, calculates an approximation line for a point group of the points, sets white road line search lines inside the approximation line in the vehicle width direction, and searches a white road line inside thereof based on luminance information on the search lines. When there is a white road line, the device sets a second white road line detection region by expanding the first region toward inside in the vehicle width direction, detects a second white road line starting point not overlapping the first point, calculates a white road line based on a point group of the first points or the second points selected on a predetermined condition, and sets the first region based on the calculated line.
