PROBLEM TO BE SOLVED: To provide an ink supplement jig which supplements ink from an ink container into an ink cartridge where the ink is used up based on a difference in pressure between the inside and outside caused by an internal reduced pressure, and which eliminates the risk of ink leakage from the ink container. SOLUTION: The tip end part of the air cylinder 17 of a pressure reducer 16 having a piston 21 movably inserted therein is connected to the air flow port 14 of the upper end part of an ink tank 11 having a nozzle tube 12 at the lower end part via a flexible tube 15. A screw rod 22 with a handle 23 fitted with the piston 21 at the tip end is screw engaged with the center screw hole 19 provided with the end cover 18 which tightly seals the rear end part of the air cylinder 17, enabling the screw sending operation of the piston 21 in the longitudinal direction. An atmospheric opening 20 is formed in the cylinder wall part near the end cover 18 of the air cylinder 17. COPYRIGHT: (C)2006,JPO&NCIPI |
