  • Publication number: 20120081450
    Abstract: A test pattern forming method is used in adjustment transport of an image forming apparatus, by the image forming apparatus which includes transport rollers transporting a medium in the sub-scanning direction and a plurality of nozzles arranged in the sub-scanning direction and repeats the transport and main scanning for moving the plurality of nozzles in the main scanning direction. The method includes forming a plurality of first patterns using a first nozzle among the plurality of nozzles, and forming a plurality of second patterns using a second nozzle among the plurality of nozzles. The plurality of first patterns is formed by repetitive transport of the medium by a first intermittent transport. The plurality of second patterns is formed by repetitive transport of the medium by a second intermittent transport. The acceleration of the first intermittent transport is more gradual than the acceleration of the second intermittent transport.

  • Patent number: 8137010
    Abstract: In an imaging device 100, as a base 110 is moved from a certain position on an upper side of an imaging area SA to a different position on a left side of the imaging area SA, a camera head 150 is pivotally rotated together with a head-side arm 160 relative to a second arm 132. Such combination of the movement of the base 110 with the pivotal rotation of the camera head 150 changes the operation mode of the imaging device 100 from a first working mode to a second working mode and enables the imaging device 100 to take images in the second working mode.
