Abstract: Provided is a liquid injecting apparatus equipped with a liquid injecting head, which is mounted on a carriage and moved reciprocally in a widthwise direction of a target, and a valve unit, which is mounted on the carriage to be supplied with liquid via a supply passage from a liquid retainer and to supply liquid to the liquid injecting head. The valve unit has a pressure chamber connected to the liquid retainer via the supply passage; a valve, which opens or closes the supply passage to supply liquid to the pressure chamber; and a flexible film member, which is displaced based on a negative pressure generated as liquid in the pressure chamber decreases to thereby operate the valve.

Abstract: An object is to provide a cartridge that is configured to be readily mountable and stir a liquid contained in the cartridge. A cartridge includes an ink pack, a first air bag and a casing provided to place the ink pack and the first air bag therein. The casing has an ink supply port, an air flow port for first air bag and an air flow port for casing that are provided on a front face of the casing in a mounting direction so that this configuration enables the cartridge to be readily mounted to the inkjet printer. The pressurized air is introduced through the air flow port for first air bag into the first air bag. This expands the first air bag to press the ink pack and thereby stir ink I contained in the ink pack.

Abstract: A liquid ejecting apparatus includes a liquid flow path connecting a liquid containing unit that contains a liquid to a liquid ejecting unit that ejects the liquid. The liquid flow path includes a supply flow path which connects the liquid containing unit to the liquid ejecting unit and a return flow path which connects the liquid ejecting unit to the liquid containing unit. When the liquid is not ejected by the liquid ejecting unit, the liquid contained in the liquid containing unit is circulated between the liquid containing unit and the liquid flow path by allowing the liquid to flow in order of the supply flow path, the liquid ejecting unit, and the return flow path. When the liquid is ejected, the liquid contained in the liquid containing unit is supplied to the common liquid chamber via both of the supply flow path and the return flow path.
