  • Patent number: 9475296
    Abstract: An ink cartridge for supplying the ink in an ink reserving chamber via an ink supply port into a recording head has a differential pressure valve mechanism disposed between an ink flow port and the ink supply port in the ink reserving chamber, whereby the ink is supplied an adequate amount to the recording head by opening or closing the differential pressure valve mechanism in accordance with an ink pressure of the recording head. As a result, it is possible to supply the ink at a substantially constant pressure to the recording head without regard to the variation in the amount of ink or the movement of the carriage.

A part of the pressure chamber is formed of a flexible film. A valve including a valve body and a valve seat adjusts an opening degree of the ink communication path. An urging member applies, to the valve, a first urging force acting in a direction in which the ink communication path is closed. An urging member applies, to the film, a second urging force that is greater than the first urging force and acts in a displacement direction in which the volume of the pressure chamber is reduced.

  • Patent number: 9290002
    Abstract: With an ink cartridge mounted on a cartridge mounting section of a printer, an apparatus-side terminal elastically comes in contact with a container-side terminal of a container-side circuit substrate. The container-side terminal includes a curved edge portion at a corner portion in which a groove of a substrate surface comes in contact with a substrate end surface. Depths of the grooves in container-side terminals are different and positions of contact sections with the apparatus-side terminals are different in the edge portions. As a result, positions in directions in which elastic forces act from the apparatus-side terminals are different for each contact section and the elastic forces having values and directions which are not uniform act on the container-side circuit substrate at different positions. Thus, it is possible to suppress positional shift of the container-side circuit substrate and to suppress contact failure between the container-side terminal and the apparatus-side terminal.
