Description
본 고안은 전자사진 방식을 이용한 사무자동화 기기(복사기,레이져빔프린터,LED프린터,일반용지팩스)에 사용되는 전자사진 프로세서의 감광드럼 청소장치에 관한 것이다.The present invention relates to a photosensitive drum cleaning apparatus of an electrophotographic processor used in office automation equipment (copier, laser beam printer, LED printer, general paper fax) using an electrophotographic method.
통상적으로 사용되는 전자사진 프로세서는 도 1에 도시한 바와같이 대전기(25)의 코로나 방전에 의해 감광드럼(photoconductive drum)(28) 표면을 전기적으로 균일하게 대전하고, LED헤드 또는 레이져 다이오드에서 발진된 광을 감광드럼(28)의 대전된 부분에 조사하거나, 노광램프(22)의 광원에 의해 원고대(21)상의 원고로부터 반사된 빛은 미러(23)을 통해 감광드럼(28)의 표면에 정전잠상(Electro-static latent image)을 형성시킨다. 이때 감광드럼(28)은 회전하며 형성된 정전잠상이 현상기(27)를 지나는 동안 토너(Toner)로 현상(develope)하여 가시상으로 변하게 되고, 이어서 급지롤러(roller)(20)에 의해서 급지된 복사용지 위해 전사기(32)의 작용으로 감광드럼(28)상의 가시상을 복사용지(31)로 전사되게 한다.A commonly used electrophotographic processor electrically uniformly charges the surface of the photoconductive drum 28 by the corona discharge of the charger 25, as shown in FIG. 1, and oscillates in the LED head or the laser diode. The reflected light is irradiated to the charged portion of the photosensitive drum 28, or the light reflected from the original on the platen 21 by the light source of the exposure lamp 22 passes through the mirror 23 to the surface of the photosensitive drum 28. An electrostatic latent image is formed in the. At this time, the photosensitive drum 28 rotates and is formed into a visible image by developing with a toner while passing through the developing device 27, and then copying fed by the paper feed roller 20. The action of the transfer machine 32 causes the visible image on the photosensitive drum 28 to be transferred onto the copy paper 31.
이때 복사용지는 정전기력에 의해 감광드럼(28)에 밀착되어지며 분리기(33)는 이 밀착된 복사용지를 분리시켜 주는 역할을 수행한다.At this time, the copy paper is in close contact with the photosensitive drum 28 by the electrostatic force and the separator 33 serves to separate the close contact with the copy paper.
그후 분리된 복사용지를 정착부(40)의 히팅롤러(heating roller)(35)와 압착롤러(pressure roller)(34)사이로 통과시키면 열과 압력에 의해 복사지면에 원고의 상이 정착되어 원하는 복사가 이루어져 트레이(39)로 배출된다.Then, when the separated copy paper passes between the heating roller 35 and the pressure roller 34 of the fixing unit 40, the image of the original is settled on the copying surface by heat and pressure to make a desired copy. It is discharged to the tray 39.
한편 전사기(32)를 지난 감광드럼(28)상에 잔여분의 토너와 잠상이 존재하게 되는데, 여기서 토너는 청소기(29)의 크리닝블레이드(clearning blade)에 의해 제거되며, 잠상은 잠상제거 램프(pre-erase lamp array)(37)에 의해 제거되도록 되어 있다.On the other hand, residual toner and latent image are present on the photosensitive drum 28 past the transfer machine 32, where the toner is removed by a cleaning blade of the cleaner 29, and the latent image is removed from the latent image removal lamp ( pre-erase lamp array (37).
상기와 같이 동작되는 전자사진 프로세서에서 종래에는 도 2에 도시한 바와같이 감광드럼 청소장치 구성도로서, 감광드럼(11)이 화살표 방향으로 회전되면서 현상된 토너가 전사기에 의해 용지로 전사되고 남은 감광드럼(11)상의 잔여분인 잔류토너(15)는 청소기(12)의 하측에 부착된 실링부재(14)를 거쳐 감광드럼(11)과 밀착된 크리닝블레이드(13)에 의해 크리닝이 되어 청소기(12)내로 쌓이도록 하는 감광드럼 청소장치인 것이다.In the electrophotographic processor operating as described above, a photosensitive drum cleaning device is conventionally constructed as shown in FIG. 2, wherein the toner developed while the photosensitive drum 11 is rotated in the direction of the arrow is transferred to the paper by the transfer machine, and the remaining photoresist is exposed. Residual toner 15 remaining on the drum 11 is cleaned by a cleaning blade 13 in close contact with the photosensitive drum 11 via a sealing member 14 attached to the lower side of the cleaner 12, thereby cleaning the cleaner 12. It is a photosensitive drum cleaning device to be stacked inside.
상기 청소장치는 청소기(12)의 상측에 크리닝블레이드(13)를 설치하기 위하여 절곡된 철판(16) 하측에 크리닝블레이드(13)를 부착하고, 상기 철판(16)을 청소기(12) 상측에 스크류(17)로 고정되게 설치하여 상기 크리닝블레이드(13)가 일측의 감광드럼(11)에 밀착되도록 하고, 상기 청소기(12) 하측에는 크리닝블레이드(13)에 의해 크리닝된 잔류토너(15)가 기기내부로 이탈하지 않도록 실링부재(14)를 부착한 것이다.The cleaning apparatus attaches the cleaning blade 13 to the lower side of the bent iron plate 16 in order to install the cleaning blade 13 on the upper side of the cleaner 12, and screw the iron plate 16 on the upper side of the cleaner 12. (17) to be fixed so that the cleaning blade 13 is in close contact with the photosensitive drum 11 on one side, and the residual toner 15 cleaned by the cleaning blade 13 on the lower side of the cleaner (12) The sealing member 14 is attached so as not to be separated inside.
이러한 종래의 감광드럼 청소장치는 감광드럼상의 잔류토너를 회수하기 위한 크리닝블레이드를 철판에 부착하고 철판을 청소기에 스크류로 고정되게 함으로서 원가 상승의 원인이 되고 크리닝블레이드를 설치시 조립시간이 많이 걸리는 문제점이 있었다.Such a conventional photosensitive drum cleaning device causes a cost increase by attaching a cleaning blade for recovering the residual toner on the photosensitive drum to the iron plate and fixing the iron plate with a screw to the vacuum cleaner, and takes a lot of assembly time when installing the cleaning blade. There was this.
따라서, 상기와 같은 문제점을 해결하기 위한 본 고안의 목적은 전자사진 프로세서의 청소장치인 크리닝블레이드를 청소기에 손쉽게 설치하여 원가를 절감시키고 조립시간을 줄일수 있도록 한 감광드럼 청소장치를 제공함에 있다.Accordingly, an object of the present invention for solving the above problems is to provide a photosensitive drum cleaning device that can be easily installed to the cleaning blade cleaning device of the electrophotographic processor to reduce the cost and assembly time.
상기와 같은 목적을 달성하기 위한 본 고안은 감광드럼상에 전사되고 남은 잔류토너를 크리닝하기 위한 청소장치인 크리닝블레이드를 손쉽게 청소기에 부착하고 감광드럼에 크리닝블레이드가 밀착되게하여 감광 드럼상의 잔류토너를 크리닝할수 있도록 함을 특징으로 한다.The present invention for achieving the above object is to easily attach a cleaning blade, which is a cleaning device for cleaning the remaining toner transferred to the photosensitive drum to the vacuum cleaner and to adhere the cleaning blade to the photosensitive drum to close the residual toner on the photosensitive drum. Characterized in that it can be cleaned.

이하 본 고안의 바람직한 실시예를 첨부된 도면에 의거 상세히 설명되어 질 것이다. 도 3은 본 고안의 감광드럼 청소장치 구성도로서, 이를 참조하여 본 고안의 구성 및 작용을 설명하면 하기와 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. 3 is a configuration of the photosensitive drum cleaning device of the present invention, with reference to this configuration and operation of the present invention as follows.
전자사진 프로세서의 감광드럼(1)상에 남은 잔류토너(5)를 크리닝하는 청소장치로서, 수지성 재질로된 청소기(2)의 상측에는 우레탄러버인 크리닝블레이드(3)를 직접 접착제로 부착하고, 하측에는 실링부재(4)를 접착제로 부착하여 상기 감광드럼(1)에 청소기(2)의 크리닝블레이드(3)가 밀착되도록 설치된 것이다. 상기 청소기(2)와 크리닝블레이드(3)는 접착제인 본드로 본딩처리하여 직접부착한 것이다.A cleaning device for cleaning the remaining toner 5 remaining on the photosensitive drum 1 of the electrophotographic processor. A cleaning blade 3, which is urethane rubber, is directly attached to the upper side of the vacuum cleaner 2 made of resin material. On the lower side, the sealing member 4 is attached with an adhesive so that the cleaning blade 3 of the cleaner 2 is in close contact with the photosensitive drum 1. The cleaner 2 and the cleaning blade 3 are directly attached by bonding with a bond which is an adhesive.
전자사진 프로세서에서 감광드럼(1)이 화살표 방향으로 회전되면서 현상된 토너가 전사기에 의해 용지로 전사되고 남은 감광드럼(1)상의 잔여분의 잔류토너(5)는 청소기(2) 상측에 직접 부착된 우레탄 러버인 크리닝블레이드(3)에 의해 크리닝되어 청소기(2)내부로 쌓이도록 하는 것이다.As the photosensitive drum 1 is rotated in the direction of the arrow in the electrophotographic processor, the developed toner is transferred to the paper by the transfer machine, and the residual toner 5 remaining on the remaining photosensitive drum 1 is directly attached to the upper side of the cleaner 2. It is to be cleaned by the cleaning blade (3) which is a urethane rubber to be stacked in the cleaner (2).
상기와 같은 감광드럼 청소장치는 청소기(2) 상측에 직접 부착된 크리닝블레이드(3)가 감광드럼(1)과 밀착된 상태에서 감광드럼(1)이 회전되므로 감광드럼(1)에 잔여분인 잔류토너(5)가 묻어 있던 상태에서 크리닝블레이드(3)에 의해 크리닝 된 잔류토너(5)는 청소기(2)내부에 쌓이게 되는 것이다. 이때 청소기(2) 하측에 부착된 실링부재(4)에 의해 크리닝된 잔류토너(5)는 청소기(2)내부에서 이탈하지 않게 되므로 기기내부의 오염을 방지할수 있는 것이다.The photosensitive drum cleaning device as described above remains in the photosensitive drum 1 because the cleaning drum 3 is directly attached to the upper side of the cleaner 2 and the photosensitive drum 1 is rotated in close contact with the photosensitive drum 1. The residual toner 5 cleaned by the cleaning blade 3 while the toner 5 is buried is accumulated in the cleaner 2. At this time, the residual toner 5 cleaned by the sealing member 4 attached to the lower side of the cleaner 2 is not separated from the inside of the cleaner 2, thereby preventing contamination of the inside of the device.
상술한 바와 같이 본 고안에 의하면 감광드럼 청소장치에서 청소기의 상측에 크리닝블레이드를 직접 부착하므로 부품수 절감에 따른 원가를 절감시킬수 있으며, 조립시간을 단축시킬수 있는 잇점이 있다.As described above, according to the present invention, since the cleaning blade is directly attached to the upper side of the cleaner in the photosensitive drum cleaning device, the cost can be reduced according to the number of parts and the assembly time can be shortened.
