CONSTITUTION: An ink container(18) is connected with a cap(18a) having a needle on the front end portion. An inject hole cap(26) has a protruded portion formed on one face of a disk to close an inject hole(10c) of an ink cartridge(10) opened by the front end portion of the ink container. A pad(14) has an attaching portion attached with the rim of an ink jet nozzle(10a) and a perforation hole(14b). An internal pressure controller(16) comprises a cylinder having a sharp front end portion inserted to the perforation hole of the pad and a piston inserted to the cylinder.
