  • Pinch roller mechanism and plotter
    Patent number: 11964842
    Abstract: A pinch roller mechanism includes a rail, a slider, a roller bracket, a spring, and a pinch roller. The rail extends in a first direction crossing the conveyance direction of a medium while being apart from a medium driving roller configured to convey the medium. The slider is supported by the rail to be movable along the rail. The roller bracket is supported by the slider to be movable with respect to the medium driving roller. The spring is provided between the slider and the roller bracket and biases the roller bracket toward the medium driving roller. The pinch roller is rotatably supported by the roller bracket while setting the axial direction in the first direction.

  • Image reading apparatus
    Patent number: 7715064
    Abstract: An image reading apparatus including a plurality of image sensors aligned in a zigzag shape and a draft carrying unit operated to a draft to carry in a sub scanning direction, the image reading apparatus forming an image data of a total of the draft from image data provided by the respective image sensors. The draft carrying unit is provided to be operated to the draft in a region aligned in a zigzag shape to constitute an inverse phase relative to the image sensor.
