PROBLEM TO BE SOLVED: To fill a case efficiently with ink while enhancing workability by performing the ink filling work and sealing work of case opening from one side of the case. SOLUTION: An ink filling opening 13 communicating with a second chamber 10 and a pressure reducing opening 14 communicating with a first chamber 9 are arranged on one side of a case 2 and both chambers 9, 10 are interconnected on the other side through an interconnecting hole 15. Since the ink filling opening 13 and the pressure reducing opening 14 are arranged on one side of the case, and ink filler and a pressure reducing unit are simply required to be brought close to the case 2 and thereby the workability of ink filling work and case opening sealing work is enhanced. Furthermore, ink can be filled efficiently because it is passed sequentially through the second and first ink chambers 10, 9. |
