Zusammenfassung:	PURPOSE: A cartridge for an ink jet printing head is provided to stably maintain negative pressure in an ink storing tank and to improve productivity of the cartridge by installing a negative pressure maintenance device in the ink storing tank. CONSTITUTION: A cartridge for an ink jet printing head includes an outer body(7), a base frame(1) and an ink storing bag(10). The base frame(1) is fixed to the outer body(7). The base frame(1) has an ink injection port(4) for feeding ink and an ink exhaust passage(5) for exhausting ink towards an ink jet. The ink storing bag(10) is fixed to the base frame(1). A negative pressure maintenance device is provided at both sides of the ink storing bag(10) so as to maintain negative pressure in the ink storing bag(10). The ink injection port(4) is sealed by means of a plug(2) and the ink exhaust passage(5) is provided with a mesh filter(3). 본 발명에 따르면 잉크젯 프린팅 헤드용 카트리지가 개시된다. 상기 잉크젯 프린팅 헤드용 카트리지는, 강성의 외부몸체와; 이 외부몸체에 고정된 강성의 베이스프레임과; 잉크의 공급 및 배출을 위한 홀들이 형성되고, 공기의 유입 및 잉크의 누출을 방지하며, 베이스프레임에 고정된 잉크 저장백; 및 이 잉크 저장백의 양 측부 상에 부착되며, 잉크의 소모에 따라 탄성 변형하여 잉크 저장백 내부의 부압을 유지하는 부압 유지수단;을 구비한다.
