摘要： A liquid cartridge includes a valve mechanism including a pressed member configured to be movable in a predetermined depressing direction, a valve element for a communicating hole, a biasing member that biases the valve element, and a switching mechanism that restricts a movable range of the pressed member, and that switches a range of restricting the movable range. The valve element closes the communicating hole with a first depressing amount, and maintains the closed state under a second depressing amount. The restricting portion has a first restricting portion that restricts the movable range to a first movable range, and a second restricting portion that restricts the movable range to a second movable range. The switching mechanism switches the movable range from one to another of a first restricting state by the first restricting portion and a second restricting state by the second restricting portion.

摘要： A liquid ejection apparatus includes: a storage chamber which is connectable to a cartridge storing liquid and stores liquid supplied from the cartridge; a movable member provided in the storage chamber and including a float and a detection target portion, the float being lower in specific gravity than the liquid stored in the storage chamber; and a detection unit which detects movement of the movable member by detecting the detection target portion. The detection target portion is movable from a first position to a third position through a second position. The detection unit is arranged to detect the detection target portion in a case where the detection target portion is present at the second position.
