Abstract:
1. A liquid container adapted to be mounted on a container mounting portion of an apparatus, comprising: a pressure chamber configured to accommodate pressurized fluid; a pressurized fluid introduction portion, adapted to be connected to a pressurized fluid supply path of the container mounting portion, and configured to introduce pressurized fluid therethrough from the apparatus to the pressure chamber; a liquid containing chamber storing liquid therein, and a volume of which is reducible by pressure due to the pressurized fluid to be supplied to the pressure chamber; a first positioning portion and a second positioning portion, adapted to receive positioning units provided at two places in the container mounting portion so as to position the liquid container relative to the container mounting portion; a liquid delivery portion, adapted to be connected to a liquid supply path of the container mounting portion and configured to deliver the liquid stored in the liquid containing chamber therethrough to the apparatus; a data storage unit, having a terminal adapted to be connected to a connection terminal of the container mounting portion; and a first surface, on which the first positioning portion, the second positioning portion and the liquid delivery portion are disposed, the first surface having a first longer side, a second longer side opposite to the first longer side, a first shorter side, and a second shorter side opposite to the first shorter side when viewed from a direction normal to the first surface; and wherein a position at which the first positioning portion is disposed, a position at which the second positioning portion is disposed, a position at which the pressurized fluid introduction portion is disposed, and a position at which the data storage unit is disposed are closer to the second longer side than a position at which the liquid delivery portion is disposed, when viewed from the direction normal to the first surface.
