Abstract: A liquid supplier can be attached to and detached from a case of a liquid ejection device, and includes a connection member located at an end of the case. The connection member includes a liquid outlet member including a liquid outlet port and a connection port, a container-side electric connector, a first receiving portion that receives a first positioning portion of the liquid ejection device, and a second receiving portion that receives a second positioning portion of the liquid ejection device. The width of the liquid supplier in the Z direction is smaller than a width in the Y direction and a width in the X direction. The liquid supplier further includes a tube whose one end is connected to the connection port, and into which liquid is injected from another end that is located outside the liquid ejection device.

Abstract: An ink cartridge is adapted to be mounted in a holder of a printer, and includes first to third surfaces and a pressing section. The first and second surfaces face each other. The third surface has first and second end sections respectively adjacent to the first and second surfaces. The pressing section presses the ink cartridge to a second surface side when the ink cartridge is mounted in the holder. The third surface has a detection section which optically detects a remaining state of ink in the ink cartridge, and an abutting section which abuts against the holder. A distance between the detection section and the second end section is shorter than a distance between the detection section and the first end section in the third surface, and the abutting section is positioned between the detection section and the second end section.

Abstract: A liquid container includes a storage portion configured to store the liquid and a connection member. The connection member is provided with a liquid outlet which is inserted with a liquid introduction portion, a container-side electrical connector which makes electrical contact with an apparatus-side electrical connection unit while receive at least +Z direction force from the apparatus-side electrical connection unit, a first receiver configured to receive a first positioning portion, a second receiver configured to receive a second positioning portion, and a recess which houses a protrusion of the case. The recess and the container-side electrical connector are formed at positions which at least partially overlap each other when viewed from a Z direction in a mounting state. In the mounting state, the width of the liquid container in the Z directions is larger than the width in the Y directions and the width in the X directions.
