Abstract: A cartridge is configured to be moved in a −Y direction and then rotated in an intersecting direction intersecting with a Y direction in an installation process of installing the cartridge in a printing device including a device terminal holder holding device terminals and having first and second positioning portions. The cartridge includes cartridge terminals and a cartridge terminal mounting portion disposed on a case and has the cartridge terminals thereon in a movable manner in the Y direction and a rotation radial direction relative to the case. The cartridge terminal mounting portion includes a restricting portion configured to restrict the movement of the cartridge terminals in the Y and Z directions during the installation process. The restricting portion includes first and second restricting portions located at respective ends in the +Y and −Y directions of the cartridge terminal mounting portion and being in contact with the respective first.

Abstract: The likelihood that a liquid discharge failure will occur in a cartridge including a liquid absorber is reduced. A cartridge includes: a liquid supply unit configured to receive a liquid supply needle; a first chamber in which a liquid absorber is arranged; a second chamber in which the liquid absorber is not arranged and the liquid supply unit is provided; and a filter that is provided between the first chamber and the second chamber. The length of the filter in a longitudinal direction is larger than half the length of the liquid absorber in the longitudinal direction, and the capillary force of the liquid absorber in a bottom face portion is larger than the capillary force of the liquid absorber in a central portion in a height direction.

Abstract: A liquid ejecting apparatus includes a liquid tank, a tank holder, a liquid ejection head, and an apparatus casing. The liquid tank includes a liquid injection port, a liquid containing portion containing the liquid injected from the liquid injection port, and a supply port supplying the liquid. The tank holder holds the liquid tank. The liquid ejection head ejects a liquid supplied from the supply port. The apparatus casing accommodates the liquid tank, the tank holder, and the liquid ejection head. The tank holder is pivotable relative to the apparatus casing with holding the liquid tank. The liquid injection port of the liquid tank is configured to be exposed to an exterior of the apparatus casing by pivoting the tank holder relative to the apparatus casing to inject the liquid into the liquid tank, while the liquid tank is held in the tank holder.
