Abstract: A liquid container includes a liquid chamber and a flexible member. The liquid chamber is configured to contain the liquid. The flexible member is subject to deformation with a decrease in internal pressure of the liquid chamber. The liquid container includes a negative pressure generator configured to maintain negative pressure in the liquid chamber by applying pressure to the flexible member. The liquid container includes a liquid outlet configured to feed the liquid out of the liquid chamber. The liquid container includes an air inlet configured to introduce air into the liquid chamber when the internal pressure of the liquid chamber is lowered to or below a preset level. The liquid container includes a detection-associated member for detection of the remaining volume of the liquid in the liquid chamber. The detection-associated member can be located inside the liquid chamber on a wall of the container body.

Abstract: A printing apparatus has a cartridge attachment section including a terminal block having apparatus-side terminals disposed on its inclined surface, and a printing material supply pipe. Among the apparatus-side terminals, one apparatus-side ground terminal located on their center in Y direction is protruded to a greater height than the other plural apparatus-side terminals. A printing material cartridge has a circuit board, a printing material supply port, and a board mount portion that is inclined at an acute angle relative to a plane extended from an opening face of the printing material supply port. The circuit board is arranged such that one cartridge-side terminal on the circuit board comes into contact with the apparatus-side ground terminal prior to the other cartridge-side terminals in the process of attachment of the printing material cartridge to the cartridge attachment section.
