PROBLEM TO BE SOLVED: To supply ink to a head mechanism by smoothly opening/closing a valve even when the ink stiffly adheres to the valve. SOLUTION: A valve accommodation chamber 32 is formed at a lower face of an ink tank. A first outflow port 33 is formed at a bottom face of the accommodation chamber 32, and a second outflow port 34 is formed at an upper face of the accommodation chamber 32. A bush 35 is formed in the periphery of the second outflow port 34. An upper end of a coil spring 36 is tightly kept in touch with the periphery of the bush 35. An outer circumferential face of a valve member 37 is held in tight contact with an inner circumferential face of a lower end of the coil spring 36. A supporting member 38 is formed at the valve member 37. When the supporting member 38 is pressed down, the ink flows out from the first outflow port 33 through a gap 36b of coils 36a. |
