  • Publication number: 20090021564
    Abstract: A fluid ejecting apparatus includes a fluid containing portion, a fluid discharging portion, a flow passage forming portion and a valve mechanism. The fluid containing portion contains fluid. The fluid discharging portion discharges the fluid. The flow passage forming portion forms a fluid flow passage that extends from the fluid containing portion to the fluid discharging portion. The valve mechanism is able to open or close the fluid flow passage. The fluid ejecting apparatus is placed in an initial state before an initial use of the fluid ejecting apparatus, wherein fluid is contained in the fluid containing portion and at least portion of the fluid flow passage from a position of the fluid containing portion to a position of the valve mechanism is filled with the fluid and the fluid flow passage is closed by the valve mechanism.

  • Publication number: 20080273048
    Abstract: The invention provides a liquid container for storing liquid to be supplied to a liquid consuming apparatus. The liquid container is constructed such that pressurized fluid is sent to its inside so that the liquid in the inside is delivered to the outside. The liquid container includes a container body which stores the liquid in its inside. The container body includes a pressurized fluid introduction port for introducing the pressurized fluid to the inside and a liquid delivery port for delivering the liquid to the outside. A detection unit is provided in the container body and outputs an output signal which is changed in accordance with a change in pressure of the liquid in the inside of the container body.

  • Patent number: 7438401
    Abstract: There is disclosed a liquid container that can be removably held in a liquid container accommodation portion by pushing the container in an insertion direction. The liquid container is mounted on a carriage having a container accommodation region. A one-push type fixing member in a position facing a surface parallel to an insertion direction in which the container is inserted into the container accommodation region is engaged with a fixing protrusion forming another one-push type fixing member and cooperating with the first-mentioned one-push type fixing member, so that the container is held in a predetermined position in a state in which the container is resiliently urged by a spring in a direction opposite to the insertion direction.

  • Publication number: 20080239039
    Abstract: A second sealing film F2 is thermally bonded onto a leading end portion R1 of an ink lead-out member 32b of an ink pack and an annular projecting portion R2 provided on an ink casing 31. Thereby, a gap D produced between the ink lead-out member 32b and the ink casing 31 can be closed from outside the ink casing 31. Accordingly, the airtightness of a space S in the ink casing 31 is kept, thus making it possible to raise the pressure in the space S and generate such a force as to crush the ink pack.

  • Publication number: 20080036834
    Abstract: An ink cartridge for an ink jet printer having a housing having at least one wall. The ink cartridge further has at least two ink chambers for containing different ink accommodated in the housing. Ink supply ports are formed in one wall of the housing within each of the ink chambers. Each of the ink supply ports has an inner opening and an outer opening. The distance from the inner opening of a first ink supply port to that of a second ink supply port adjacent to the first ink supply port is different from a second distance from the outer opening of the first ink supply opening to that of the second ink supply port.

  • Publication number: 20080030558
    Abstract: Since a bypass flowing passage which communicates with the inside of a bag part not through a second valve mechanism is provided for an outlet part, ink can be filled from the outlet part into the bag part in spite of the existence of the second valve mechanism. Further, after an ink pack that has been yet filled with ink has been housed in an inner case, the ink is filled into the ink pack. Therefore, when a first seal film is welded to the inner case, since the bag part is not bulky, the ends of the bag part are caught in a cartridge case. Therefore, the maximum amount of ink for the inner volume of the cartridge case can be filled. Further, since a bypass flowing passage is blocked after the ink has filled into the ink pack, contamination of air bubbles into the bag part through the bypass flowing passage is prevented.

  • Publication number: 20070222843
    Abstract: A printer includes a recording head having a nozzle that ejects ink and a suction pump that draws the ink through the nozzle. A valve unit and a filter are arranged in a passage that supplies the ink to the recording head. A controller of the printer operates the suction pump to perform suction/suspension in which suction of the ink from the passage through the nozzle and suspension of the suction are alternately repeated with the valve unit maintained in a closed state, thus promoting joining of bubbles on the filter. The controller then operates to open the valve unit to drain the joint bubbles from the filter, together with the ink, using negative pressure accumulated in the passage.

    Abstract: An ink cartridge and an ink cartridge holder maintain the relative position between the information reading section of the ink cartridge holder and the information storing unit of the ink cartridge, which should be aligned accurately, even if the ink cartridge has instability to the ink cartridge holder due to variation in each product. The ink cartridge which supplies ink to a recording apparatus includes: a substantially rectangular parallelepiped ink cartridge main body holding ink; a connection electrode section provided on part of a first side of the ink cartridge main body and including a connection terminal; an ink supply unit provided in a front surface intersecting the first wall; and a positioning section guiding a positioning member of the recording apparatus to the vicinity of the connection electrode on the front surface so that the positioning member opposes the connection electrode section in the direction parallel with the connection electrode section.
