In other words, the speed of the ink is kept constant regardless of the ink amount.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

본 발명은 전자기 방식을 이용한 잉크제트 프린터의 프린터헤드에 있어서, 자장을 형성하기 위하여 상반된 극의 영구자석을 대향으로 설치하고, 상기 영구 자석에 의하여 발생된 자장내에 자장의 방향에 수직이 되도록 사각형상의 제1관 내부에 공급용 평행전극을 설치하고, 도전성 잉크가 채워진 상기 공급용 평행전극사이에 전류펄스를 가함으로서 공급되는 잉크의 양을 조절하며, 이의 단부쪽으로 방출되는 잉크는 연통된 버퍼체임버로 인가되며, 상기 방출된 잉크를 가속하기 위하여 상기 버퍼체임버와 연통하는 한쌍의 가속용 평행전극을 설치함을 특징으로 한다.The present invention provides a printer head of an ink jet printer using an electromagnetic method, in which a permanent magnet of opposite poles is disposed opposite to each other to form a magnetic field, and in a rectangular shape so as to be perpendicular to the direction of the magnetic field in the magnetic field generated by the permanent magnet. The supplying parallel electrode is installed inside the first tube, and the amount of ink supplied is controlled by applying a current pulse between the supplying parallel electrodes filled with conductive ink, and the ink discharged toward the end portion thereof is connected to the buffer chamber. And a pair of acceleration parallel electrodes communicating with the buffer chamber to accelerate the discharged ink.

4. 발명의 중요한 용도4. Important uses of the invention

전자기력에 의해 도전성 잉크를 분사하는 잉크제트 헤드에 있어서 분사되는 잉크를 항시 일정한 속도로 토출해낼 수 있도록 별도의 제2관을 정치하여 정전압을 인가함으로서 잉크의 속도를 잉크양에 관계없이 일정하게 유지할 수 있다.In the ink jet head which injects the conductive ink by electromagnetic force, the second pipe can be fixed at a constant speed so that the ink can be discharged at a constant speed at all times. have.
