Abstract:
1. 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: 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.
