본고안은 전자사진 응용기기에 관한 것으로 특히 레이저빔 프린터에 적당하며, 현상기를 삽입이나 추출시에 슬리브에 파손을 방지하기에 적당한 구조로 이루어진 보호장치에 관한 것이다.The present invention relates to an electrophotographic application device, and particularly to a laser beam printer, and to a protective device having a structure suitable for preventing damage to a sleeve when inserting or extracting a developer.
종래에는 제 1 도와 같은 레이저빔 현상기에서 종이카세트(14)를 출발하는 종이는 드럼(16)과 전사코로나(15)사이를 지나간다.Conventionally, paper starting from the paper cassette 14 in a laser beam developer such as the first diagram passes between the drum 16 and the transfer corona 15.
이때 현상기(9)에서는 토너를 현상기슬리브(10) 표면에 부착하여 드럼(16)표면에 화상정보와 같게 부착시켜주면 드럼(16)은 회전하면서 종이위에 토너를 입혀준다. 이때 전사코로나(15)가 작동하여 드럼(16)에 부착되어있는 토너를 종이위에 전사시켜 준다.At this time, in the developer 9, the toner is attached to the surface of the developer sleeve 10 and attached to the surface of the drum 16 in the same manner as the image information. The drum 16 rotates to coat the toner on the paper. At this time, the transfer corona 15 is operated to transfer the toner attached to the drum 16 onto the paper.
토너가 부착된 종이는 정작부(18)를 지나 배지부(19)를 거쳐 배치트레이(20)에 쌓이게 된다.The toner-attached paper is accumulated in the batch tray 20 via the median unit 18 and the discharge unit 19.
그러나 상기의 전사과장에서 현상기 슬리브에 손상이 생기거나 이물질이 부착되어 있으면 토너의 성능을 저해하고 인쇄가 불균형 하게되며 고장수리나 잼제거시 현상기를 레이저 프린터에서 추출해야하나 이때 보관 및 운반하기에 매우 불편하였고 항상 슬리브가 현상기에서 노출되어 있기 때문에 사용자에게 토너가 묻기 쉬울뿐만 아니라 슬리브에 손상을 입힐 염려가 큰문제점이었다.However, if the developer sleeve is damaged or foreign matter is attached to the transfer section, the performance of the toner may be impaired, the printing may be unbalanced, and the developer should be extracted from the laser printer when troubleshooting or removing jams. It was inconvenient, and because the sleeve was always exposed in the developer, it was not only easy to get toner on the user, but also a possibility of damaging the sleeve.
따라서 본고안은 상기의 구조에서 발생되는 문제점을 해결하기 위하여 현상기의 슬리브에 필요에 따라 보호용 커버를 씌울수 있도록 한 것으로 이를 첨부도면과 함께 상세히 설명하면 다음과 같다.Therefore, the subject matter of the present invention is to cover the cover of the developing device as necessary to solve the problems occurring in the above structure as described in detail with the accompanying drawings as follows.
제 2 도는 본고안에 대해 현상기 보호장치의 정면 및 측면도인 것으로, 보호장치는 슬리브의 곡면을 보호하는 면을 형성한 커버(1)와 커버를 슬리브전면에 당기고 내리는 작용을 하기위한 손잡이(8), 그리고 손잡이와 커버를 연동시키기 위한 링크(5), 커버의 상승방향을 안내하는 회전가이드(3)로 구성된다.2 is a front and side view of the developing device protector for the present case, the protecting device comprising a cover (1) having a surface protecting the curved surface of the sleeve and a handle (8) for pulling and lowering the cover to the front of the sleeve; And a link 5 for interlocking the handle and the cover, and a rotation guide 3 for guiding the upward direction of the cover.
먼저 커버(1)는 그 폭과 높이가 슬리브(10)보다 크게하고 하단의 양측에 힌지핀(1b)를 돌출시켜 현상기(9)의 슬리브(10) 전면에 설치하되 슬리브의 원주면 보호하기 위한 만곡면(1a)을 커버(1)의 전면에 형성하여 ""형상을 갖춘다.First, the cover 1 has a width and a height greater than that of the sleeve 10, and protrudes the hinge pins 1b on both sides of the lower end, so that the cover 1 is installed on the front of the sleeve 10 of the developer 9, but for protecting the circumferential surface of the sleeve. The curved surface 1a is formed on the front surface of the cover 1 so that "Equipped with shape.
손잡이(8)는 손으로 잡기에 편한 ""형으로 형성하여 현상기(9)의 중앙 상단에서 수직으로 삽입한다.Handle (8) is easy to hold by hand It is formed in the shape of " inserted vertically at the top of the center of the developer 9.
커버(1)는 손잡이(8)를 현상기(9)에 설치한 상태에서 커버(1)와 손잡이(8)를 링크(5)(5')로 각각 연결하되 링크(5)(5')의 선단에 힌지핀(7)을 끼워 손잡이(8)의 선단과 연결하고 링크(5)(5')의 하단에 힌지핀(4)을 끼워 커버(1)의 상단 양측에 연결하여 링크(5)(5')의 중앙으로 힌지핀(6)을 끼워서 현상기(9)에 고정한다.The cover 1 connects the cover 1 and the handle 8 to the links 5 and 5 'with the handle 8 installed in the developer 9, Insert the hinge pin (7) at the tip to connect with the tip of the handle (8) and connect the hinge pin (4) at the bottom of the link (5) (5 ') to the upper both sides of the cover (1) to link (5). Insert the hinge pin 6 into the center of 5 'and fix it to the developer 9.
상기의 연결과정에서 손잡이와 커버의 연결부분의 구멍은 장공으로 함이 링크의 회동운동을 직선운동으로 바꿀수 있다.In the above connection process, the hole of the connection part of the handle and the cover is a long hole, so that the rotational motion of the link can be changed into a linear motion.
손잡이(8)와 커버(1) 및 링크(5)(5')가 연결된 상태에서 커버(1)하단의 힌지핀(16)을 설치한 슬리브(10)의 양단에서 설치한 슬리브 보호용 회전가이드(3)(3')에 연결한다.Rotating guide for protecting sleeves installed at both ends of the sleeve 10 in which the hinge pin 16 at the bottom of the cover 1 is installed while the handle 8 and the cover 1 and the links 5 and 5 'are connected ( 3) (3 ').
이러한 구성으로 이루어진 본고안은 제 2a, b 도의 상태에서 커버(1)가 슬리브(10)의 전면에 위치하여 슬리브(10)의 원주면을 커버(1)의 만곡면(1a)으로 보호하게 된다.In this configuration, the cover 1 is positioned in front of the sleeve 10 in the state of FIGS. 2a and b to protect the circumferential surface of the sleeve 10 by the curved surface 1a of the cover 1. .
이러한 보호상태에서는 현상기(9)를 레이저빔 프린터에서 분리시키거나, 고장수리시 및 잼제거시 외부공간에 노출되는 슬리브(10)의 면을 커버(1)로써 보호하여 슬리브의 파손, 이물질의 접근등을 방지할 수 있고, 수리자나 사용자의 손이나 의복에 토너가 묻는 것을 방지할 수 있다.In this state of protection, the developer 9 is detached from the laser beam printer, or the cover 10 is protected by the cover 1, which is exposed to the external space during the repair and removal of the jam, to damage the sleeve and to access foreign objects. And the like, and toner can be prevented from getting into the hands or clothes of a repairman or a user.
수리가 끝나거나 기계를 사용하기 위해서는 현상기(9)를 레이저프린터에 삽입해야 하며 레이저프린터에 실치된 상태에서는 슬리브(10)를 노출시켜서 토너를 드럼(16)의 표면에 부착시켜야 하는 이때에는 제 3a, b 도와 같이 현상기(9)의 상면으로 튀어나온 손잡이(8)를 현상기(9) 삽입전에 눌러준다.When the repair is finished or the machine is to be used, the developer 9 must be inserted into the laser printer, and when the toner is attached to the surface of the drum 16 by exposing the sleeve 10 while the laser printer is mounted, the third Press the knob 8 protruding to the upper surface of the developer 9 as shown in FIG.
손잡이(8)를 누르면 그 힘은 연결된 링크(5)(5')에 전달되어 링크(5)(5')는 힌지핀(6)을 중심으로 회동하여 손잡이(8)와 연결된 선단은 하강하고 커버(1)와 연결된 후단은 상승하게되므로 슬리브(10)전면에 위치하고 있던 커버(1)는 승강하는 작용을 하며 이때 커버(1)의 만곡면(1a)이 슬리브(10)에 접촉될 염려가 있으나 커버(1)하단의 힌지핀(1b)이 회전가이드(3)(3')에 끼워져 있어서 커버(1)의 하단은 회전가이드(3)(3')의 회전방향에 따라 원호적인 운동으로 상승하게 되므로 슬리브(10)의 전면을 전혀 건드리지 않으면서 승상한다.When the handle 8 is pressed, the force is transmitted to the connected links 5 and 5 'so that the links 5 and 5' rotate about the hinge pin 6 so that the tip connected to the handle 8 is lowered. Since the rear end connected to the cover 1 is raised, the cover 1 located on the front surface of the sleeve 10 moves up and down, and at this time, the curved surface 1a of the cover 1 may be in contact with the sleeve 10. However, the hinge pin 1b at the bottom of the cover 1 is fitted to the rotation guides 3 and 3 'so that the lower end of the cover 1 is circular in motion according to the rotation direction of the rotation guides 3 and 3'. As it rises, it elevates without touching the front of the sleeve 10 at all.
따라서 슬리브(10)에 토너를 묻히고 이 토너를 드럼(16)에 접촉할 때 전달해 준다.Therefore, the toner is buried in the sleeve 10 and delivered when the toner contacts the drum 16.
이상에서와 같이 본고안은 현상기를 레이저프린터에서 분리할때 현상기의 손잡이를 잡아당겨 하강하는 커버로 노출된 슬리브의 전면을 막아 외격이 접촉되는 것을 방지하여 필요한 작업을 수행하고, 현상기를 레이저프린터에 장착할때에는 잡아당긴 손잡이를 눌러 링크의 연동에 의해 커버가 승강하여 차단했던 슬리브의 전면을 개방시켜 기존의 토너 공급작용을 할수 있는 것이어서 외부의 외격에서 슬리브를 최대한 보호할수 있는 효과로 제품의 사용수명을 연장하고 사용자의 의복이나 손을 보호할 수 있을 뿐만아니라 현상기에 슬리브의 보호기능을 부여하여 사용효과를 향상시킨 이점이 있는 것이다.As described above, this proposal pulls the handle of the developer when the developer is removed from the laser printer and prevents the outer contact from touching the exposed sleeve by the lowering cover to perform the necessary work. When installing, it is possible to supply the existing toner by opening the front of the sleeve that the cover was lifted and blocked by the linkage by pressing the pulled handle, which can protect the sleeve from the external outer space. In addition to extending the protection of the user's clothes or hands, as well as giving the protective function of the sleeve to the developing device has the advantage of improving the use effect.
