  • Patent number: 10464331
    Abstract: The liquid container includes: a container main body including a containment chamber containing a liquid and has some walls including a front-end wall, a rear-end wall, and an upper-surface wall; a liquid outlet connected to a liquid-consuming device to flow out the liquid from the containment chamber to the liquid-consuming device; a liquid inlet on the upper-surface wall at a position closer to the rear-end wall and accepts injection of the liquid from outside of the container main body into the containment chamber; and a visual recognition portion that is provided on the rear-end wall and is see-through so that a position of a liquid surface of the liquid in the containment chamber is recognizable. The rear-end wall has scale marks as indexes of an amount of the liquid in the containment chamber on an outer wall surface and an inner wall surface.

  • Patent number: 9505213
    Abstract: An ink jet recorder includes a support unit configured to support a recording medium, and a mobile unit including a plurality of containers containing inks of identical composition and a head configured to eject the ink supplied from any one of the plurality of containers. The ink jet recorder is configured to record an image on the recording medium in such a manner that the head performs main scanning by ejecting the ink while changing positions in a first direction, and the mobile unit performs sub-scanning by moving in a second direction intersecting with the first direction.
