The set of cartridges includes a first and a second ink cartridge, and each cartridge includes a main body and a particular protrusion positioned adjacent to a bottom wall of the main body and extending from a portion of the main body in the insertion direction away from an ink chamber. The main body includes a first wall, the ink chamber, a communication portion disposed at the first wall; a second wall disposed opposite the first wall, and the bottom wall. The ink chamber is disposed between the first and second walls.

Abstract: An ink cartridge is removably mounted to a recording apparatus. The ink cartridge includes a main body and first and second protrusions. A particular end of the second protrusion extends further than a particular end of the first protrusion in the insertion direction. The main body includes an ink chamber, a particular wall having a first end and a second end opposite the first end in a further direction, a communication portion that selectively places an interior of the ink chamber and an exterior of the ink chamber into fluid communication, a holding portion positioned opposite the particular wall, and a bottom wall. A distance from a rear end of the bottom wall to the particular end of the second protrusion in the insertion direction is less than a distance from a rear end of the holding portion to an end of the second protrusion in the insertion direction.

Abstract: An ink cartridge includes an ink chamber that stores ink and a body. The body has a first edge, a second edge, and an ink supply portion positioned at the first wall. A first detection portion is positioned at a particular end of the first edge, and a second detection portion positioned at a further end of the first edge opposite to the particular end of the first wall. The first detection portion and the second detection portion are positioned to be detected during an installation process. A remaining amount detection portion is positioned closer to the second wall than each of the first detection portion and the second detection portion, wherein the remaining amount detection portion is positioned and configured to be detected during an installation process.

Abstract: A liquid cartridge includes a cartridge main body comprising a liquid chamber and an end surface. The liquid cartridge also includes a communicating portion protruding from the end surface of the cartridge main body in a protruding direction which is perpendicular to a width direction. The liquid chamber includes a wide portion and a narrow portion which is narrower than the wide portion in the width direction, and the narrow portion is offset toward a first side of the cartridge main body in the width direction.
