Description
본 고안은 화상형성장치에서 관한 것으로써 더욱상세하게는, 용지에서 발생하는 정전기를 제거하여 용지의 중송을 방지하는 정전기제거부재를 갖는 화상형성장치에 관한 것이다.The present invention relates to an image forming apparatus, and more particularly, to an image forming apparatus having an electrostatic removing member that removes static electricity generated from a paper and prevents paper feeding.
도 1은 종래의 화상형성장치인 잉크젯프린터의 개략적인 구성을 나타낸 우측단면도이다.1 is a right sectional view showing a schematic configuration of an inkjet printer which is a conventional image forming apparatus.
잉크젯프린터(1)는 인쇄명령에 의하여 라인피드모터(10)가 회전하면서 급지부(20)에 구성된 캠축(21)이 회전되어 픽업로울러(22)가 회전하여 용지(P)를 급지하고, 급지되는 용지(P)는 라인피드모터(10)의 회전력이 아이들기어(11)에 전달되고 아이들기어(11)가 피드로울러(12)를 회전시키면 용지(P)는 피드로울러(12)와 용지가이드(13)에 연결된 프릭션로울러(14)사이로 들어가 베이스프레임(40)에 놓여진다.The inkjet printer 1 rotates the camshaft 21 configured in the paper feed unit 20 while the line feed motor 10 rotates according to a printing command, and the pickup roller 22 rotates to feed the paper P. The paper P is transmitted to the idle gear 11 when the rotational force of the line feed motor 10 is rotated and the idle gear 11 rotates the feed roller 12. The paper P is fed to the feed roller 12 and the paper guide ( 13 is inserted into the friction roller 14 connected to the base frame 40 is placed.
용지(P)가 삽입되면 메인프레임(30)에 구성된 인쇄장치부(31)가 작동되면서 베이스프레임(40)에 놓여진 용지(P)를 인쇄장치부(31)에 구성된 노즐부(32)에서 잉크를 뿌려지면서 인쇄가 이루어 지게 된다.When the paper P is inserted, the printing device unit 31 configured in the main frame 30 is operated, and the paper P placed on the base frame 40 is ink in the nozzle unit 32 configured in the printing device unit 31. Printing is done while spraying.
차츰 인쇄가 이루어지면서 용지(P)는 피드로울러(12)에 의해 연동되던 이동로울러(15)가 배출로울러(16)를 연동시켜 용지(P)가 삽입되어 배출됨으로써 한 장의 용지(P)가 인쇄완료되는 것이다.As printing is gradually performed, the paper P is interlocked by the feed roller 12, and the moving roller 15 interlocks the discharge roller 16 so that the paper P is inserted and discharged, thereby printing one sheet of paper P. It's done.
이상과 같은 구성으로 이루어지는 잉크젯프린터(1)에서 인쇄되는 용지(P)를 급지할때에 용지(P) 자체가 갖고 있는 정전기로 인하여 급지되는 용지(P)가 여러장 겹쳐서 인쇄장치부(31)로 삽입되는 이른바 중송현상이 발생하여 인쇄품질을 저하시키는 문제점이 발생하였다.When feeding the paper P printed by the inkjet printer 1 having the above-described configuration, the paper P fed by the static electricity possessed by the paper P itself is overlapped with several sheets of the printing device unit 31. The so-called mid-feed phenomenon occurred to be inserted into the problem occurred to reduce the print quality.
본 고안은 종래의 문제점을 해소하기 위한 것으로, 정전기제거부재를 구성하여 용지내에서 발생되는 정전기를 제거하는 것을 목적으로 하는 것이다.The present invention is to solve the conventional problems, it is an object to remove the static electricity generated in the paper by configuring the static elimination member.
상기의 목적을 달성하기 위하여 본 고안은, 접지선를 갖는 고정프레임에 브러쉬가 부착부재에 의하여 부착되어, 고정프레임에 부착되는 정전기제거부재를 구성하여, 화상형성장치의 메인프레임에 고정부재로 고정하여 용지에서 발생하는 정전기를 제거하는 것을 특징으로 하는 것이다.In order to achieve the above object, the present invention, the brush is attached to the fixed frame having a ground wire by an attachment member, to configure the static elimination member attached to the fixed frame, the paper fixed to the main frame of the image forming apparatus by a fixed member It is characterized by removing the static electricity generated from.

본 발명이 실시된 상태를 나타내는 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 고안에 의하여 실시되는 화상형성장치인 잉크젯프린터에서 프런트커버를 제거한 사시도를 나타내는 것이다.Figure 2 shows a perspective view of the front cover removed from the inkjet printer which is an image forming apparatus implemented by the present invention.
잉크젯프린터(100)는 보텀부(110)에 메인프레임(120)이 고정되고, 메인프레임(120)에 인쇄장치부(130), 피드로울러(140), 프릭션로울러(150), 배지로울러(160), 급지장치부(170) 등을 구성하여 프런트케이스(미도시)와 리어케이스(180)를 조립하는 것이다.The inkjet printer 100 has a main frame 120 fixed to the bottom part 110, and a printing device unit 130, a feed roller 140, a friction roller 150, and a discharge roller (130) on the main frame 120. 160, the paper feeding unit 170, and the like, to assemble the front case (not shown) and the rear case 180.
본 고안은 이와 같은 구성을 갖는 잉크젯프린터(100)에서, 고정프레임(210)에 접지선(212)을 갖고, 상기 고정프레임(210)에는 브러쉬(216)를 갖는 부착부재(214)가 부착된 구성을 갖는 정전기제거부재(200)를 고정부재(220)로 메인프레임(120)에 고정한다.The present invention has a configuration in which the inkjet printer 100 having such a configuration has a ground wire 212 on the fixed frame 210, and an attachment member 214 having a brush 216 is attached to the fixed frame 210. Fixing the static elimination member 200 having a fixed member 220 to the main frame 120.
또한, 고정프레임(210)에 형성된 접지선(212)은 메인프레임(120)의 측벽에 형성된 접지단자(122)에 접지한다.In addition, the ground line 212 formed on the fixed frame 210 is grounded to the ground terminal 122 formed on the side wall of the main frame 120.
도 3은 이와 같이 구성되는 정전기제거부재(200)가 메인프레임(120)에 부착된 상태를 나타내는 정면도이다.3 is a front view illustrating a state in which the static electricity removing member 200 configured as described above is attached to the main frame 120.
이와 같은 구성으로 이루어지는 잉크젯프린터(100)의 작동상태를 도 4와 도 5를 이용하여 설명하면 다음과 같다.The operation of the inkjet printer 100 having such a configuration will be described with reference to FIGS. 4 and 5 as follows.
인쇄명령에 의하여 라인피드모터(112)가 회전하면서 급지장치부(170)의 캠축(172)이 회전되고, 픽업로울러(174)가 회전하여 용지(P)가 피드로울러(140)와 용지가이드(152)에 고정되는 프릭션로울러(150) 사이로 급지된다.As the line feed motor 112 is rotated by the printing command, the cam shaft 172 of the paper feeding unit 170 is rotated, and the pickup roller 174 is rotated so that the paper P feeds the feed roller 140 and the paper guide ( It is fed between the friction roller 150 fixed to the 152.
또한, 라인피드모터(112)의 회전력이 아이들기어(114)에 전달되고 아이들기어(114)의 회전력이 피드로울러(140)를 회전시켜 피드로울러(140)가 회전되면서 용지(P)가 피드로울러(140)와 프릭션로울러(150)사이로 삽입된다.In addition, the rotational force of the line feed motor 112 is transmitted to the idle gear 114 and the rotational force of the idle gear 114 rotates the feed roller 140, so that the feed roller 140 is rotated, the paper P feed roller It is inserted between the 140 and the friction roller 150.
삽입되는 용지(P)가 프릭션로울러(150)를 지나갈때에 정전기를 갖고 있으면, 금속재의 프릭션로울러(150)와 맞닿는 정전기제거부재(200)에 의하여 정전기는 메인프레임(120)으로 흐르게 되어 삽입되는 용지(P)의 정전기를 제거하게 되는 것이다.If the inserted paper P has static electricity when passing through the friction roller 150, the static electricity flows to the main frame 120 by the static electricity removing member 200 which is in contact with the friction roller 150 made of metal. The static electricity of the paper P to be inserted is to be removed.
부연하여 설명하면 금속재의 프릭션로울러(150)로 흐른 정전기는 브러쉬(214)로 흐르게 되고, 브러쉬(214)에서 다시 고정프레임(210)으로 흘러 고정프레임(210)에 형성된 접지선(212)에 의하여 메인프레임(120)에 형성된 접지단자(122)에접지되는 것이다.In detail, the static electricity flowing to the friction roller 150 made of metal flows to the brush 214, and flows from the brush 214 to the fixed frame 210 again by the ground wire 212 formed in the fixed frame 210. It is grounded to the ground terminal 122 formed on the main frame 120.
이와 같이 정전기가 제거된 용지(P)는 인쇄장치부(130)에 의하여 인쇄되어 배지로울러(160)에 의하여 배출되어 인쇄가 완료되는 것이다.As such, the paper P from which the static electricity is removed is printed by the printing apparatus 130 and discharged by the discharge roller 160 to complete printing.
이상에서 설명한 바와같이 본 고안에 의하여 용지가 갖고 있는 정전기를 제거하게 되어, 용지의 중송을 방지함으로써 인쇄품질을 향상시킬수가 있는 것이다.As described above, the present invention removes the static electricity possessed by the paper, thereby improving print quality by preventing paper feeding.
