Abstract
A technique for preventing a decrease in an amount of liquid contained in a cartridge is provided. The cartridge includes a liquid containing portion and a liquid supply portion. The liquid supply portion is coupled to the liquid inlet portion due to rotational movement of a containing-portion-rear-wall side of the cartridge downward around a rotation fulcrum, which is located on the insertion direction side, of the cartridge mounting portion. In the insertion direction, a first distance between a liquid flowing-in port and a rear wall inner surface, which is an inner surface of a containing portion rear wall, is shorter than a second distance between the liquid flowing-in port and a front wall inner surface, which is an inner surface of a containing portion front wall.
