    摘要: A liquid ejection apparatus ejects liquid retained in a liquid container from a liquid ejection head. The apparatus includes a liquid supply needle having an outlet line that can be connected to the interior of the liquid container, a liquid supply line connecting the outlet line of the liquid supply needle to the recording head, and a control valve provided in the liquid supply line. The control valve closes the liquid supply line when negative pressure is applied to the liquid ejection head. A seal valve is arranged between the control valve and the liquid supply needle in the liquid supply line. The seal valve seals the liquid supply line using liquid pressure applied from the control valve to the outlet line. Accordingly, the liquid is prevented from leaking from the liquid supply needle when the liquid container is separated from the liquid supply needle.
