  • Patent number: 10882346
    Abstract: An ink jet recording apparatus of a line-recording-head type includes one or more recording heads using the same ink and performs recording of an image by conveying a recording medium using multiple passes through a recording region of the recording head while the recording medium is repeatedly conveyed backward and forward to speed up recording and improve image quality. A recording head is controlled to provide that an amount of ink applied to a recording medium in a case where the recording medium is conveyed at a first speed is smaller than an amount of ink applied to the recording medium in a case where the recording medium is conveyed at a second speed higher than the first speed in both of a case where the recording medium is accelerated and a case where the recording medium is decelerated.

  • Publication number: 20190030910
    Abstract: An inkjet recording apparatus includes a tank, a pivot member and a first surface. The tank has a storage chamber configured to store a liquid therein. The pivot member is disposed in the storage chamber. The pivot member is configured to pivotally move about an axis extending in an axial direction in a case where a level of a liquid surface of the liquid becomes equal to a predetermined liquid level. The pivot member includes a float and a first protrusion. The float has a specific gravity smaller than that of the liquid. The first protrusion protrudes toward the first surface. The first protrusion and the first surface provide a gap therebetween. The first protrusion is at a position in contact with the liquid in a state where the level of the liquid surface of the liquid is at the predetermined liquid level.
