Abstract

PURPOSE: A wet type electrophotographic printer is provided to make the picture developed on a specific position uniform by suppressing the uneven transmission of the deflection of the rotational speed due to vibration of a photosensitive belt. CONSTITUTION: The diameter(D') of a squeeze backup roller(46) is the same as the diameter(D) of a drive roller(31). The length of the circumference of the drive roller is the same as that of the squeeze backup roller. Thus, the mutual rotational cycle is agreed. The developing length(L) between neighboring contact points(B) of each squeeze backup roller is in accordance with the length of the circumference of the drive roller. Since the rotational cycle of the drive roller is in accordance with the rotational cycle of the squeeze backup roller, the uneven transmission of the deflection of the rotational speed due to vibration or eccentricity of a photosensitive belt(30) is suppressed.

Description

습식 전자사진방식 프린터{Liquid electricphotographic printer}Liquid electrophotographic printer

본 발명은 습식 전자사진방식 프린터에 관한 것으로, 상세하게는 감광벨트에 현상되는 화상이 균일하도록 구조가 개선된 습식 전자사진방식 프린터에 관한 것이다.The present invention relates to a wet electrophotographic printer, and more particularly, to a wet electrophotographic printer having an improved structure so that an image developed on a photosensitive belt is uniform.

일반적으로 습식 전자사진방식 프린터는 소정의 색상을 지닌 고체상의 토너와, 용매의 기능을 하는 액상의 캐리어를 혼합한 현상액을 무한궤도를 주행하는 감광벨트와 같은 감광매체에 형성된 정전잠상 영역에 부착함으로써, 원하는 화상을 얻을 수 있도록 된 프린팅기기이다.In general, a wet electrophotographic printer attaches a developer mixed with a solid toner having a predetermined color and a liquid carrier serving as a solvent to an electrostatic latent image region formed on a photosensitive medium such as a photosensitive belt traveling in an endless track. It is a printing device that can get a desired image.

도 1을 참조하면, 일반적인 습식 전자사진방식 프린터는 구동롤러(11)와 가이드롤러(12) 및 조향롤러(13)에 지지되어 무한궤도를 주행하는 감광벨트(10)와, 상기 감광벨트(10)에 형성되는 정전잠상 영역에 각 칼라에 대응되는 현상액을 부착시키도록 된 복수의 현상롤러(22)와, 상기 각 현상롤러(22)에 근접설치된 복수의 스퀴즈롤러(24)와, 상기 감광벨트(10)를 사이에 두고 상기 스퀴즈롤러(24) 각각에 대응되게 설치된 복수의 스퀴즈백업롤러(26)를 포함하여 구성된다.Referring to FIG. 1, a general wet electrophotographic printer is supported by a driving roller 11, a guide roller 12, a steering roller 13, and a photosensitive belt 10 that travels in a caterpillar, and the photosensitive belt 10. A plurality of developing rollers 22 to attach a developing solution corresponding to each color to the electrostatic latent image area formed on the back plate, a plurality of squeeze rollers 24 provided adjacent to each of the developing rollers 22, and the photosensitive belt. And a plurality of squeeze back up rollers 26 provided to correspond to each of the squeeze rollers 24 with the intervals of 10 in between.

상기 감광벨트(10)는 상기 구동롤러(11)에 의해 구동주행되면서, 대전기(14)에 의해 소정 전위의 대전 상태를 유지하며, 각각의 현상롤러(22)에 근접 설치된 레이저 주사유니트(17)에서 주사된 빔(beam)에 의해 전위가 변화됨으로써 정전잠상이 형성된다. 상기 각 현상롤러(22)는 토너와, 액상의 캐리어가 혼합된 현상액을 감광벨트(10)의 정점잠상 영역에 선택적으로 부착되도록 한다. 이와 같이 현상액이 부착된 감광벨트(10)는 상기 각각의 스퀴즈롤러(24)와 스퀴즈백업롤러(26) 사이로 압착되어 통과되면서, 감광벨트(10)에 부착된 현상액 중 액상의 캐리어는 제거되고 토너(T)는 필름화된다. 그리고, 감광벨트(10)의 표면에 필름화된 토너(T)는 전사롤러(15)에 전사되며, 표면 에너지 차이에 의해 전사롤러(15)로부터 그 전사롤러(15)와 정착롤러(16) 사이로 통과되는 인쇄용지(P)에 인쇄된다.The photosensitive belt 10 is driven and driven by the driving roller 11, and maintains a charged state at a predetermined potential by the charger 14, and a laser scanning unit 17 provided in proximity to each developing roller 22. Electrostatic latent image is formed by changing the potential by the beam (beam) scanned from the (). Each of the developing rollers 22 selectively attaches a developer mixed with a toner and a liquid carrier to the peak latent image region of the photosensitive belt 10. As described above, the photosensitive belt 10 to which the developer is attached is pressed and passed between the respective squeeze rollers 24 and the squeeze back up roller 26, so that the carrier of the liquid in the developer attached to the photosensitive belt 10 is removed and the toner is removed. (T) is filmed. Then, the toner T filmed on the surface of the photosensitive belt 10 is transferred to the transfer roller 15, and the transfer roller 15 and the fixing roller 16 from the transfer roller 15 by the surface energy difference. It is printed on the printing paper P passed through.

그런데, 상기와 같은 종래의 습식 전자사진방식 프린터는 각롤러(11)(24)(26)의 배치 및 직경의 상호관계가 고려되지 않았다. 따라서, 상기 감광벨트(10)를 주행구동시키기 위해 상기 구동롤러(11)를 회전시킬 경우, 구동롤러(11)의 제조공정상의 오차에 의해 발생하는 편심과, 회전시 발행하는 진동의 크기변화에 의해 속도 편차가 발생된다. 그리고, 이러한 속도 편차에 의해 감광벨트(10)가 불균일한 주행속도로 주행됨으로써, 각각의 스퀴즈롤러(24) 사이를 통과하는 주행주기가 불규칙하게 된다. 따라서, 감광벨트(10)가 각각의 스퀴즈롤러(24)와 스퀴즈백업롤러(26) 사이를 주행되면서 그 표면에 순차적으로 현상 및 필름화되는 화상이 불균일하게 되어 결국 인쇄의 질이 떨어지는 문제점이 있다.By the way, in the conventional wet electrophotographic printer as described above, the relationship between the arrangement and diameter of the rollers 11, 24 and 26 is not considered. Therefore, when the driving roller 11 is rotated to drive the photosensitive belt 10, the eccentricity caused by the error in the manufacturing process of the driving roller 11 and the magnitude of the vibration generated during the rotation are caused. This causes a speed deviation. And, by the speed deviation, the photosensitive belt 10 travels at an uneven traveling speed, whereby the running cycle passing between the respective squeeze rollers 24 becomes irregular. Therefore, as the photosensitive belt 10 travels between the squeeze rollers 24 and the squeeze back up rollers 26, the images developed and filmed sequentially on the surface thereof become non-uniform, resulting in poor print quality. .

본 발명은 상기와 같은 문제점을 해결하기 위해 창안된 것으로, 감광벨트의 표면에 형성되는 화상이 불균일하게 되는 것을 억제하도록 구조가 개선된 습식 전자사진방식 프린터를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide a wet electrophotographic printer having an improved structure to suppress an unevenness of an image formed on a surface of a photosensitive belt.

도 2를 참조하면, 본 발명의 실시예에 따른 프린터는 가이드롤러(32)와 조향롤러(33) 등에 지지되어 무한궤도를 주행하는 감광벨트(30)와, 상기 감광벨트(30)를 지지하는 동시에 주행구동시키는 구동롤러(31)와, 상기 감광벨트(30)의 일면에 토너와 액상의 캐리어가 혼합된 현상액을 부착하는 복수의 현상기(40)와, 상기 각각의 현상기(40)에 근접설치되어 상기 감광벨트(30)의 일면에 레이저 빔(beam)을 주사하여 정전잠상을 형성시키는 레이저 주사유니트(37)를 포함하여 구성된다. 도면부호 34는 상기 감광벨트(30)에 근접설치되어 그 일면을 소정전위의 대전상태로 유지시켜주는 대전기를 나타낸 것이다.2, the printer according to the embodiment of the present invention is supported on the guide roller 32 and the steering roller 33, such as a photosensitive belt 30 for traveling in an endless track, and for supporting the photosensitive belt 30 A driving roller 31 for driving and driving at the same time, a plurality of developing units 40 for attaching a developing solution mixed with a toner and a liquid carrier to one surface of the photosensitive belt 30, and a close installation to each of the developing units 40. And a laser scanning unit 37 for scanning the laser beam on one surface of the photosensitive belt 30 to form an electrostatic latent image. Reference numeral 34 denotes a charger that is installed close to the photosensitive belt 30 and maintains one surface thereof in a charged state at a predetermined potential.

상기 구동롤러(31)는 상기 감광벨트(30)에 접촉되도록 설치되어 소정의 구동수단에 의해 회전구동되면서, 마찰력에 의해 감광벨트(30)를 주행시키게 된다.The driving roller 31 is installed to be in contact with the photosensitive belt 30 to be rotated by a predetermined driving means to drive the photosensitive belt 30 by friction.

상기 각 현상기(40)는 감광벨트(30)의 일면에 형성된 정전잠상 영역에 현상액을 부착시키는 현상롤러(42)와, 상기 감광벨트(30)의 일면에 접촉회전되면서 그 일면에 부착된 현상액으로부터 캐리어를 제거하여 토너(T)를 필름화하는 스퀴즈롤러(44)와, 상기 스퀴즈롤러(44)가 감광벨트(30)에 밀착되도록 스퀴즈롤러(44)에 대응되는 감광벨트(30)의 타면에 접촉회전되도록 설치된 스퀴즈백업롤러(46)를 포함하여 구성된다.Each of the developing units 40 includes a developing roller 42 for attaching a developing solution to an electrostatic latent image region formed on one surface of the photosensitive belt 30, and a developing solution attached to one surface while rotating in contact with one surface of the photosensitive belt 30. The squeeze roller 44 for filming the toner T by removing the carrier, and the other surface of the photosensitive belt 30 corresponding to the squeeze roller 44 so that the squeeze roller 44 is in close contact with the photosensitive belt 30. It is configured to include a squeeze back up roller 46 installed to be in contact rotation.

상기 현상롤러(42)는 감광벨트(30)와의 사이에 소정의 현상갭이 유지되도록 배치되며, 현상기 내에 회전가능하게 설치된다. 상기 현상갭 사이로 공급되는 현상액은 현상롤러(42)에 의해 감광벨트(30)의 일면에 형성된 정전잠상 영역에 부착된다. 상기 스퀴즈롤러(44)는 감광벨트(30)의 일면에 접촉되어 감광벨트(30)의 주행시 그 마찰력에 의해 회전가능하도록 현상기(40) 내에 설치된다. 상기 스퀴즈백업롤러(46)는 상기 스퀴즈롤러(44)에 대응되도록 감광벨트(30)의 타면에 접촉가능하게 설치된다. 도면부호 B는 각 현상기(40)의 스퀴즈백업롤러(46)가 감광벨트(30)의 타면에 접촉되는 접촉점을 나타낸 것이다. 이러한 스퀴즈백업롤러(46)는 감광벨트(30)를 스퀴즈롤러(44) 쪽으로 가압하면서, 그 감광벨트(30)와의 접촉시 마찰력에 의해 피동회전된다.The developing roller 42 is arranged to maintain a predetermined developing gap between the photosensitive belt 30 and is rotatably installed in the developing machine. The developer supplied between the developing gaps is attached to the electrostatic latent image region formed on one surface of the photosensitive belt 30 by the developing roller 42. The squeeze roller 44 is installed in the developing device 40 to be in contact with one surface of the photosensitive belt 30 so as to be rotatable by its friction when the photosensitive belt 30 is traveling. The squeeze backup roller 46 is installed to be in contact with the other surface of the photosensitive belt 30 so as to correspond to the squeeze roller 44. Reference numeral B denotes a contact point at which the squeeze backup roller 46 of each developing unit 40 is in contact with the other surface of the photosensitive belt 30. The squeeze back-up roller 46 is driven by the frictional force upon contact with the photosensitive belt 30 while pressing the photosensitive belt 30 toward the squeeze roller 44.

여기서, 스퀴즈백업롤러(46)의 직경(D´)은 상기 구동롤러(31)의 직경(D)과 동일하다. 즉, 구동롤러(31)의 원주길이(πD)와 스퀴즈백업롤러(46)의 원주길이(πD´)가 동일하게 되어 상호 회전주기가 일치된다.Here, the diameter D 'of the squeeze back up roller 46 is equal to the diameter D of the drive roller 31. That is, the circumferential length πD of the drive roller 31 and the circumferential length πD 'of the squeeze back up roller 46 are equal to each other so that the mutual rotation periods coincide.

또한, 상기 각 스퀴즈백업롤러(46)는 상기 서로 이웃한 접촉점들(B) 사이의 현상거리(L)가 상기 구동롤러(31)의 원주길이(πD)와 일치되도록 설치되는 것이 바람직하다. 이와 같이, 상기 현상거리(L)를 상기 구동롤러(31)의 원주길이(πD)와 동일하게 하여 스퀴즈백업롤러들(46) 사이를 통과하는 감광벨트(30)의 주행주기와 그 감광벨트(30)를 주행구동시키는 구동롤러(31)의 회전주기를 일치시키는 것이 가능하게 된다.In addition, each of the squeeze back-up roller 46 is preferably installed such that the developing distance (L) between the adjacent contact points (B) coincide with the circumferential length (πD) of the drive roller (31). As such, the developing distance L is equal to the circumferential length πD of the driving roller 31, and the driving cycle of the photosensitive belt 30 passing between the squeeze back up rollers 46 and its photosensitive belt ( It is possible to match the rotation period of the drive roller 31 which drives 30 to drive.

이와 같이 상기 구동롤러(31)와 스퀴즈백업롤러(46)의 회전주기를 상호 일치시킴으로써, 종래와 같이 구동롤러(31)의 회전시 편심 또는 불규칙한 진동에 의한 회전속도의 편차가 각 현상기(40)를 통과하는 감광벨트(30)에 불균일하게 전달되는 것이 방지된다. 따라서, 감광벨트(30)의 원하는 화상 영역에 각 현상기(40)를 통과하면서, 균일한 화상을 형성시키는 것이 가능하게 된다.As such, the rotation periods of the driving roller 31 and the squeeze back-up roller 46 coincide with each other, whereby the deviation of the rotational speed due to eccentricity or irregular vibration during rotation of the driving roller 31 as in the prior art is developed in each of the developing units 40. It is prevented from being unevenly transmitted to the photosensitive belt 30 passing through. Therefore, it becomes possible to form a uniform image while passing through each developing unit 40 in a desired image area of the photosensitive belt 30.

상기와 같은 본 발명의 습식 전자사진방식 프린터에 따르면, 구동롤러와 스퀴즈백업롤러의 회전주기를 일치시킴으로써, 회전시 구동롤러의 편심, 진동에 의한 회전속도의 편차가 감광벨트에 불균일하게 전달되는 것이 억제되어 각각의 현상기에 의해 감광벨트의 소정위치에 현상되는 화상이 균일하게 된다.According to the wet electrophotographic printer of the present invention as described above, by matching the rotation period of the driving roller and the squeeze back-up roller, the deviation of the rotational speed due to the eccentricity and vibration of the driving roller during rotation is unevenly transmitted to the photosensitive belt. The image developed at the predetermined position of the photosensitive belt by each developer is made uniform.
