Abstract: The cartridge is attached to the cartridge attachment through an attaching operation in which the cartridge is completely inserted into the cartridge attachment in an insertion direction, or a horizontal direction, and then a rear portion of the cartridge in the insertion direction is moved in a rotation attaching direction containing a gravity-directional component with a deep side of the cartridge in the insertion direction used as a rotation fulcrum. This cartridge includes: a main body a liquid reservoir that is disposed inside the main body; a liquid inlet that is formed across the main body and leads to an interior of the liquid reservoir; a liquid reservoir body that includes a liquid supply section through which communicates with the liquid reservoir; and an adapter that is mounted on the liquid reservoir body and has an insertion aperture into which the liquid introduction section is to be inserted.

Abstract: A liquid ejection apparatus includes a liquid tank, a liquid ejection head, and a tank holder. The liquid tank includes a displacement unit and a tank body part. The displacement unit has a liquid injection port. The tank body part has a liquid containing portion containing liquid introduced from the liquid injection port, and having a supply port supplying the liquid. The liquid ejection head ejects the liquid supplied from the supply port. The tank holder holds the liquid tank. The displacement unit is movable so as to displace the liquid injection port relative to the tank body part and the tank holder so that the liquid injection port is exposed to an exterior of the tank holder to inject the liquid into the liquid tank, while the tank body part is held in the tank holder and is not displaced relative to the tank holder.
