Patent ID: 8425017

Claim:
A liquid droplet ejecting apparatus comprising: a recording head that ejects liquid droplets onto a recording medium to record an image; a supply-use tank whose inside is sectioned by a first elastic film capable of elastic deformation into a liquid chamber that stores a liquid for image recording to be supplied to the recording head and a gas chamber that is filled with a gas; a supply-use flow path that is capable of being opened and closed and interconnects the supply-use tank and the recording head such that the liquid is capable of circulating therethrough; a first pump that pumps the liquid stored in the liquid chamber of the supply-use tank to the recording head via the supply-use flow path that has been opened by supplying the liquid from an external tank in which the liquid is stored to the liquid chamber of the supply-use tank; a control unit that controls of the flow path to: supply the liquid to the liquid chamber such that the liquid chamber is filled with the liquid in a state where the supply-use flow path is closed, hold the first elastic film in a state where the first elastic film is caused to press against an inner wall of the gas chamber, thereafter open the supply-use flow path to cause the first elastic film to move from the state where the elastic film is caused to press against the inner wall of the gas chamber to a state where pressing is released, and supply, with the first pump, the liquid from the external tank to the recording head via the supply-use tank and the supply-use flow path; and a first elastic member that configures the inner wall of the gas chamber, is disposed in a position in the gas chamber that faces the first elastic film, and is capable of elastic deformation when pressed by the first elastic film from the liquid chamber side.
