  • Patent number: 8678548
    Abstract: An image recording apparatus includes: a recording head which records an image to a recording surface of a recording medium; a scanning mechanism which reciprocates the recording head along a scanning direction; a recording direction deciding unit which decides a recording direction along which the recording head scans with respect to the recording surface of the recording medium to record the image, from a first direction along the recording surface and a second direction intersecting with the first direction and along the recording surface; and a changing unit which changes one of the scanning direction of the recording head and a direction of the recording medium to bring the recording direction with respect to the recording surface decided by the recording direction deciding unit and the scanning direction of the recording head in line.

  • Patent number: 8496310
    Abstract: There is provided a recording apparatus including: a head jetting liquid droplets from nozzles; and a controller controlling the head to perform a recording jetting-operation for jetting the liquid droplets toward a recording medium from the nozzles at each of drive periods, and a flushing operation for performing maintenance on the nozzles by jetting the liquid droplets from the nozzles prior to the recording jetting-operation. The controller controls the head so that with respect to each of the nozzles, a total liquid discharge amount in the flushing operation becomes less in a case of jetting a liquid droplet at a first drive period in the recording jetting-operation, in comparison with a case of not jetting the liquid droplet at the first drive period.

  • Patent number: 8388121
    Abstract: A liquid-jetting apparatus includes: a liquid-jetting head which jets the liquid; a liquid tank which stores the liquid; a first flow passage which connects the liquid-jetting head and the liquid tank; a gas-liquid separating section which is arranged on the first flow passage and which separates the liquid and a gas in the liquid; a gas communication passage which connects the gas-liquid separating section and the liquid tank and through which the gas in the gas-liquid separating section is transported to the liquid tank; a second flow passage which communicates an upstream side and a down stream side of the gas-liquid separating section; and a switching mechanism which selectively switches between a first passage route for supplying the liquid through only the first flow passage and a second passage route for supplying the liquid through the second flow passage.

  • Patent number: 8136921
    Abstract: A liquid droplet ejection apparatus includes: a flow path unit including first and second pressure chambers for first and second liquids, respectively, and first and second nozzles communicating with the first and second pressure chambers, respectively, each of the first and second nozzles including a tip opening; and a pressure generating unit which generates a pressure for the liquids in the first and second pressure chambers to eject the liquids through the tip openings of the first and second nozzles. A diameter of the tip opening of the first nozzle is larger than that of the tip opening of the second nozzle and a length of the first nozzle is shorter than that of the second nozzle.
