Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION

본 발명은 베리어(barrier)를 개구부 측면에 고정함으로서 드롭(drop)의 직진성을 향상시킬 수 있는 잉크-젯 프린터의 헤드 장치 및 잉크 순환 방법에 관한 것이다.The present invention relates to a head apparatus and an ink circulation method of an ink-jet printer capable of improving the straightness of a drop by fixing a barrier to an opening side.

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

본 발명은 플레이트의 일측면에 베리어(barrier)를 형성하므로서 고해상도의 화상을 형성시킬 수 있는 잉크-젯 프린터의 헤드 장치 및 잉크 순환 방법을 제공하는데 있다.The present invention provides a head apparatus and an ink circulation method of an ink-jet printer capable of forming a high resolution image by forming a barrier on one side of a plate.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

본 발명은 케버티(cavity)상에 열을 가하여 잉크를 가열 및 증발시켜 증기압을 발생시키는 가열부와, 상기 가열부에 에너지를 공급하는 전극부와, 실리콘 재질로 형성된 기판층과 전극부와의 경계면을 절연시키는 저항층과, 상기 전극부와 가열부와 저항층을 잉크와의 화학작용에 의해 발생하는 부식 및 산화를 방지하기 위한 보호막과, 상기 가열부의 증기압에 의해 형성된 드롭을 기록용지상에 분사시키는 복수의 개구부와. 상기 복수의 개구부가 형성된 플레이트의 일측면은 상기 가열부의 열에 의해 생성된 버블을 개구부 측으로 안내시켜 주고, 상기 잉크를 상기 보호막 측으로 흐르도록 하는 베리어로 구성된 것이다.The present invention provides a heating unit for generating a vapor pressure by heating and evaporating ink by applying heat on a cavity, an electrode unit for supplying energy to the heating unit, a substrate layer formed of a silicon material, and an electrode unit. A resist layer for insulating the interface, a protective film for preventing corrosion and oxidation caused by chemical reaction between the electrode portion, the heating portion and the resistive layer, and a drop formed by the vapor pressure of the heating portion on the recording paper. A plurality of openings to be sprayed; One side surface of the plate on which the plurality of openings are formed is configured as a barrier that guides bubbles generated by the heat of the heating unit to the opening side and flows the ink toward the protective layer.

4. 발명의 중요한 용도4. Important uses of the invention

본 발명은 베리어(barrier)를 플레이트에 설치하므로서 상기 플레이트의 강도를 보강시켜 주며, 또한 드롭(drop)을 개구부로부더 직진성을 구현할 수 있으며, 도트(dot)의 형상을 종래의 타원형 또는 주변의 미세한 점의 발생을 없애주므로서 고해상도의 화상을 형성할 수 있으며, 잉크가 공급로에서 순환로로 흐를때 일정한 속도를 유지할 수 있기 때문에 헤드 내부의 손상을 방지할 수 있으며, 또한 화상의 선명도를 높여주므로서 사용자로 하여금 신뢰감을 향상시킬 수 있는 효과가 있다.The present invention reinforces the strength of the plate by installing a barrier (barrier) on the plate, it can also implement a straightness from the drop (drop) to the opening, and the shape of the dot (dot) of the conventional oval or fine around It is possible to form a high resolution image by eliminating dots, and to maintain a constant speed when ink flows from the supply path to the circulation path, thereby preventing damage to the inside of the head and also increasing the sharpness of the image. There is an effect that can improve the user's confidence.
