Abstract

본 발명은 잉크 제트 프린터에 관한 것으로서, 종래에는 많은 부품의 사용에 의한 갭 조정장치가 구성되면서, 상기 갭 조정을 수동으로 조작하여 사용자가 상당히 불편하고, 인쇄매체(A4용지, 봉투)의 두께에만 대응되므로서, 인쇄매체의 다양한 사용이 불가능하고 한정된 인쇄만 하는 문제점이 있었다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink jet printer, and in the related art, a gap adjusting device using a large number of parts is constructed, and thus the user is quite inconvenient to manually operate the gap adjusting, and only to the thickness of the printing medium (A4 paper, envelope) Correspondingly, various uses of the print media are not possible and there is a problem of limited printing.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해 헤드 갭 조정장치의 구성을 간단히 하며 헤드 갭 조정을 자동으로 실시하면서, 잉크 제트 프린터의 헤드와 종이의 일정거리를 정확하게 유지시켜, 인쇄매체(종이)의 두께가 일정하지 않더라도, 항상 인쇄매체(종이)와 헤드에 구성된 노즐과의 거리를 일정하게 유지되도록 하므로서, 미세한 두께의 인쇄매체(종이)변화에도 대응시킬 수 있는 잉크 제트(INK JET) 프린터의 헤드 캡(HEAD GAP) 조정장치이다.Therefore, in order to solve the above problems, the present invention simplifies the configuration of the head gap adjusting device and automatically adjusts the head gap, while maintaining a certain distance between the head of the ink jet printer and the paper accurately, thereby printing media (paper). ) Ink jet printers that can cope with changes in print media (paper) of small thickness while maintaining a constant distance between the print media (paper) and the nozzles formed in the head, even if the thickness of the HEAD GAP adjuster
