- 액체잉크를 토출하는 프린터 헤드와 접속되고 액체잉크가 저장되는 잉크실이 내부에 형성된 서브탱크와,상기 서브탱크에 접속되고 상기 잉크실에 공급되는 액체잉크가 저장된 메인탱크와,상기 잉크실과 연결되고 상기 서브탱크에 형성된 압력제어구멍에 접속되며 상기 잉크실의 내압을 조정하는 압력제어수단을 가진 잉크젯 프린터의 잉크공급장치에 있어서,상기 잉크실에는, 액체잉크 안에서 뜨는 밀봉용 플로우트 부재와 상기 밀봉용 플로우트 부재를 상기 잉크실에서의 잉크액면의 변화에 따라 상하이동이 가능하게 지지하는 지지부를 구비한 역류방지부가 형성되며,상기 밀봉용 플로우트 부재가 상기 압력제어수단인 서브탱크 감압부로부터의 흡인에 의해 상기 잉크실에서의 잉크액면의 상승에 따라 위로 이동되었을 때,상기 압력제어구멍의 잉크실측 개구를 밀봉하고, 잉크실측 개구로부터의 상기 액체잉크의 역류를 방지하도록 구성된 것을 특징으로 하는 잉크젯 프린터의 잉크공급장치.
- 제 1 항에 있어서,상기 잉크실측 개구는 상기 서브탱크의 상벽면에 개구하고,상기 지지부는 상기 잉크실측 개구를 둘러싸는 동시에 상기 상벽면에 연결되어 아래쪽으로 뻗어 형성되며,상기 밀봉용 플로우트 부재는 상기 지지부에 보유되어 상기 잉크실측 개구의 아래쪽에 위치한 것을 특징으로 하는 잉크젯 프린터의 잉크공급장치.
- 제 1 항 또는 제 2 항에 있어서,상기 잉크젯 프린터는, 인쇄매체를 지지하는 매체지지부를 구비한 본체부재와, 상기 매체지지부에 지지된 상기 인쇄매체와 대치하여 상기 본체부재에 대하여 상대이동이 가능하게 설치된 캐리지를 구비하며,상기 메인탱크가 상기 본체부재에 설치되고,상기 프린터 헤드 및 상기 서브탱크가 상기 캐리지에 설치된 것을 특징으로 하는 잉크젯 프린터의 잉크공급장치.
- 제 1 항 또는 제 2 항에 있어서,상기 압력제어수단은 상기 서브탱크의 내압을 부압상태로 감압하는 서브탱크 감압부 및 상기 서브탱크의 내압을 정압상태로 가압하는 서브탱크 가압부로 이루어지되, 상기 서브탱크 감압부 및 서브탱크 가압부는 1대의 기체이송펌프에 의해 작동되는 것을 특징으로 하는 잉크젯 프린터의 잉크공급장치.
- 제 1 항 또는 제 2 항에 있어서,상기 서브탱크는 내부의 잉크실에 플로우트 수용부 및 그 안에서 상하이동하여 마그네트를 고정설치하고 있는 플로우트를 구비하고 잇고, 상기 마그네트의 자 기를 검출하는 자기센서를 구비하고 있는 것을 특징으로 하는 잉크젯 프린터의 잉크공급장치.
- 제 1 항 또는 제 2 항에 있어서,상기 서브탱크에는, 상기 서브탱크의 하부에 형성된 개구부로부터 연장하는 제1 도출로 및 상기 제1 도출로의 개구부보다 높은 위치에 형성된 다른 개구부로부터 연장하는 제2 도출로가 설치되는 것을 특징으로 하는 잉크젯 프린터의 잉크공급장치.
- 제 6 항에 있어서,상기 제1 도출로로부터 튜브공간을 통하여 잉크를 프린터 헤드에 보내며,상기 튜브공간의 기포를 상기 제2 도출로를 통하여 잉크실에 배출하는 것을 특징으로 하는 잉크젯 프린터의 잉크공급장치.
