Abstract

PURPOSE:To reduce the quantity of gas dissolving in ink and make the negative pressure in print head constant by sinking a plastic film which contains injection ink within liquid of a constant level. CONSTITUTION:A plastic film 2 containing ink 3 is sunk in liquid 5 such as water or other of a constnt liquid level which flows through influent pipe 6 provided in an ink cartridge case 1 and flows out into effluent pipe 7. Then, always a constant pressure is applied to the ink 3 in the film 2 by way of the liquid 5, by which the quantity of gas dissolving in the ink is reduced and the negative pressure in print head is made constant. Hence, satisfactory recording may be performed by the ink drops being spouted from the printed head.
