PROBLEM TO BE SOLVED: To speed up replenishing ink. SOLUTION: A flexible container 11 is made to communicate with an ink cartridge 1 via a replenishment port 16 and a replenishment linkage port 17 when the ink is to be replenished. The interior of a case 10 where the flexible container 11 is stored is sucked to expand the flexible container 11. A negative pressure inside the flexible case 11 is increased, so that the ink is replenished at a fast suction speed. |
