Abstract:
1. A cartridge configured to be removably mounted to a liquid ejection device, the liquid ejection device comprising a first row and second row of conductive contact members arranged along a first direction, and a liquid introduction portion, the cartridge being configured to be received by a first force in a second direction that is perpendicular to the first direction from the first row and second row of conductive contact members and from the liquid introduction portion and by a second force in a third direction perpendicular to the first direction and second direction from the first and second rows of conductive contact members in a state that the cartridge is mounted on the liquid ejection device, the cartridge comprising: a liquid supply portion configured to be connected to the liquid introduction portion; a first row of contact portions arranged along the first direction and configured to come into contact with the first row of conductive contact members; a second row of contact portions arranged along the first direction and configured to come into contact with the second row of conductive contact members; a first engaged portion configured to be engaged with the liquid ejection device; and a second engaged portion configured to be engaged with the liquid ejection device, wherein: the first engaged portion has a first opposing portion that, in a mounting process for mounting the cartridge to the liquid ejection device, opposes a first end portion of the liquid ejection device located on a side facing the second direction, the second engaged portion has a second opposing portion that, in a mounting process for mounting the cartridge to the liquid ejection device, opposes a second end portion of the liquid ejection device located on the side facing the second direction, the first and second engaged portions are configured so as to, when in a state of being engaged with the liquid ejection device, restrict the first and second rows of contact portions from moving away from the first and second rows of conductive contact members, and a central contact portion is located at a center among the first row of the contact portions and is passed by a plane that passes through a central point between the first and second engaged portions and that is perpendicular to the first direction.
