    Abstract: A wall-shaped enclosure that forms a space which can accommodate a head chip is formed in a projecting manner at a lower end of a lower case member. Since a cylindrical thick part is formed at the lower end of the lower case member, the lower case member is unlikely to be bent, particularly around the wall-shaped enclosure and a part where the wall-shaped enclosure is disposed. The head chip that is disposed in the space of the lower case member which is unlikely to be bent is unlikely to be subjected to an external force, and the cover member absorbs torsion generated between the head chip and the lower case member so that the head chip is even more unlikely to be subjected to the external force.

  • Patent number: 9365042
    Abstract: A liquid supply device 10 is equipped with a liquid containing chamber 16, a transport tube 15 for sending the liquid inside the chamber 16 to a liquid jetting device 20, first and second members 171 and 172 sandwiching the tube 15, and a cam 173 that determines the position of the first member 171 relative to the second member 172. The tube 15 is equipped with an elastic portion 151 that elastically deforms and is flattened. In the first rotation position, the cam 173 arranges the first member 171 such that there is a space that allows the liquid to flow inside the part 151 between the first and second members 171, 172. In the second rotation position, the cam 173 arranges the first member 171 such that the elastic portion 151 is flattened by the first and second members 171, 172, and the liquid inside cannot flow.

  • Patent number: 9150028
    Abstract: A liquid cartridge includes: a valve chamber; a moving member; first and second sealing parts; and a second liquid channel. The valve chamber is defined by a side wall surface including central, first-end side, and second-end side regions. The central region defines a first space having a first cross-sectional area. The first-end side region defines a second space having a second cross-sectional area. The second-end side region defines a third space having a third cross-sectional area. The second and third cross-sectional areas are greater than the first cross-sectional area. The moving member moves from a first position where the first and second sealing parts are positioned within the first and third spaces, respectively, and the valve closes the second liquid channel, to a second position where the first and second sealing parts are positioned within the second and first spaces, respectively, and the valve opens the second liquid channel.

  • Patent number: 9056480
    Abstract: A drop in the throughput of continuous printing operations caused by refilling a subtank with ink is suppressed. The control unit of an inkjet printer 1 fills subtanks 11a-11d with ink whenever ink consumption exceeds a reference volume q during continuous printing. Ink is suctioned by producing negative pressure in subtanks 11a-11d during the ink refill operation while ink continues being supplied to the inkjet head 7 from pressure adjustment chambers 13a-13d disposed between subtanks 11a-11d and inkjet head 7. Ink ejection from the inkjet head 7 can therefore continue even during the ink refill operation. By setting the volume of the pressure adjustment chambers 13a-13d greater than at least the amount of ink that is ejected during the ink refill operation, there is no need to interrupt printing in order to replenish the ink supply.
