  • Patent number: 9555637
    Abstract: A cartridge 1 is provided with an ink pack 9, an air bag 10 capable of abutting the ink pack 9, and a pressurizing chamber 11 that stores the ink pack 9 and the air bag 10. In the case where the amount of ink in the ink pack 9 decreases, pressurized air is introduced into the air bag 10, the ink pack 9 is pressed against the air bag 10, and thereby the internal pressure of the ink pack 9 is increased. After that, pressurized air is introduced into the pressurizing chamber 11 so as to increase the internal pressure of the pressurizing chamber 11 and pressurize the ink pack 9 from outside. Accordingly, the ink in the ink pack 9 is supplied from an ink supply port 12 to the inkjet printer 2.

  • Patent number: 8857949
    Abstract: A liquid ejecting apparatus includes a liquid ejecting head having a nozzle formation surface with a nozzle that discharges a liquid. A cleaning member wipes the nozzle formation surface to remove liquid that has adhered thereto. An absorption member of a porous material deforms under pressure and includes an absorption surface that contacts the cleaning member to absorb liquid that has adhered thereto. A pressure member moves between a pressure position, in which the pressure member applies pressure to the absorption surface of the absorption member, and a non-pressure position, in which the pressure member does not apply pressure to the absorption surface. A movement mechanism moves the pressure member from the non-pressure position to the pressure position to cause the absorption member to deform, thereby dispersing the liquid absorbed by the absorption member from the cleaning member via the absorption surface into the interior of the absorption member.

  • Patent number: 8646888
    Abstract: An ink cartridge has a label portion on a wall surface of one periphery of a case forming an ink accommodating unit. The label unit has a lamination structure in which a plurality of layers with different properties and states are laminated, and includes an optical functional layer that allows light (first wavelength of light) with a predetermined wavelength to pass and an optical reflective layer that reflects the first wavelength of light, and the optical reflective layer is a surface side of the case. When the optical reflective layer is heated from a thermal head of a heating unit directed to the label portion, the optical reflective layer irreversibly raises absorptivity of the first wavelength of light with respect to a received range.

  • Patent number: 8585194
    Abstract: An ink cartridge has a label portion on a wall surface of one periphery of a case forming an ink accommodating unit. The label unit has an optical functional layer that allows a predetermined wavelength of light to pass, an optical dispersion layer that includes hollow bodies, and an optical absorptive layer that absorbs the first wavelength of light, which are laminated in this order, and the optical absorptive layer is a surface side of the case. When the optical reflective layer is heated from a heating unit directed to the label portion at a temperature of damaging the hollow bodies, the dispersion of the light is suppressed by the damage to the hollow bodies, and the transmittance of the wavelength of light is irreversibly raised.

  • Patent number: 8430485
    Abstract: A liquid-feeding pump that feeds liquid, which is sucked out from a liquid container, into an ejection nozzle is provided. In addition, a circulation pump that discharges the liquid, which is sucked out from the liquid container, to the liquid container is provided. Moreover, a decompression pump, which generates a pressure for operating the liquid-feeding pump, is used as a drive source of the circulation pump. Therefore, a driving mechanism for the circulation pump need not be additionally provided. Accordingly, it is possible to simplify a configuration of a liquid ejecting apparatus while being capable of agitating the inner portion of the liquid container by using the circulation pump.
