본 고안은 전자사진 복사기의 현상기에 관한 것으로, 특히 닥터 블레이드(Doctor Blade)를 조절하여 닥터갭(Doctor Gap)을 자유로이 조정가능하도록 안출한 현상기의 닥터캡 조절장치에 관한 것이다.The present invention relates to a developing device of an electrophotographic copying machine, and more particularly, to a doctor cap adjusting device of a developing device which freely adjusts a doctor gap by adjusting a doctor blade.

종래에는 제 1 도와 같이 현상기(1)는 하우징(2)의 개구측에 슬리브(3)가 피복된 마그네틱로울러(4)를 회전되게 설치하고, 그 슬리브(3)의 하부에 닥터블레이드(7)을 나사등으로 고정설치하여 슬리브(3)와 닥터블레이드(7) 사이의 닥터갭(11)을 일정하게 유지시켰던 것이다.Conventionally, as the first diagram, the developing device 1 installs the magnetic roller 4 coated with the sleeve 3 on the opening side of the housing 2 so as to rotate, and the doctor blade 7 below the sleeve 3. Was fixed with a screw or the like to keep the doctor gap 11 between the sleeve 3 and the doctor blade 7 constant.

즉, 상기 닥터 갭(11)은 현상제가 일정한 두께로 슬리브(3)상에 붙어 나오도록 하기 위한 것이다.That is, the doctor gap 11 is for the developer to stick on the sleeve 3 to a certain thickness.

그런데 현상기(1)의 최초 제작시 닥터캡(11)을 미리 조정한 상태에서 출고되기 때문에 정밀도가 높으나 이는 고정식이므로 사용자가 사용도중 닥터캡을 적절하게 조정이 불가능한 결점이 있었다.By the way, when the first manufacturing of the developing device (1), the doctor cap 11 is released in a pre-adjusted state, so the precision is high, but because it is a fixed type, there was a drawback that the user cannot properly adjust the doctor cap during use.

본 고안은 이러한 종래의 결점을 해소하고자 한것으로, 수 mm에서 1mm이하의 갭을 유지해야 하는 현상기의 닥터갭을 제작시 손쉽게 조절할 수 있을뿐만 아니라 전문가가 아니라도 사용자가 미세조정이 가능하여 기계의 품질향상은 물론 신뢰도를 높일수가 있는 것이다.The present invention is intended to solve these conventional drawbacks, not only can easily adjust the doctor gap of the developer that needs to maintain a gap of several mm to less than 1mm, and even the expert can fine-tune the user's quality The improvement can of course increase the reliability.

이하 본 고안을 첨부도면에 따라서 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도면 제 2 도 내지 제 5 도는 본 고안의 실시예로써, 부호 1은 현상기 본체이며, 그 현상기 본체(1)은 하우징(2)의 개구부측에 슬리브(3)가 피복된 마그네틱로울러(4)를 회전되게 설치하고, 내부에는 호퍼(5)를 회전되게 설치한다.2 through 5 are embodiments of the present invention, reference numeral 1 denotes a developer main body, and the developer main body 1 includes a magnetic roller 4 having a sleeve 3 coated on an opening side of the housing 2. It is installed to rotate, and inside the hopper (5) is installed to rotate.

부호 6은 본 고안의 닥터갭 조절장치로써, 그 닥터갭 조절장치(6)는 닥터블레이드(7), 축봉(8), 캠(9), 스프링(10)으로 구성된다.Reference numeral 6 is a doctor gap control device of the present invention, the doctor gap control device 6 is composed of a doctor blade (7), a shaft (8), a cam (9), a spring (10).

상기 닥터블레이드(7)은 슬리브(3)의 하방에 위치되게 하우징(2)에 설치하여 그 슬리브(3)와의 사이에 닥터갭(11)을 일정하게 유지시키도록 한다.The doctor blade 7 is installed in the housing 2 to be positioned below the sleeve 3 so as to keep the doctor gap 11 constant between the sleeve 3 and the sleeve 3.

상기 축봉(8)은 하우징(2)의 양측벽에 회동되게 설치하며, 그 축봉(8)의 양단과 중간부에 캠(9)을 일체로 축착시킨다.The shaft bar 8 is pivotally installed on both side walls of the housing 2, and integrally compresses the cam 9 at both ends and the middle of the shaft bar 8.

상기 축봉(8)의 일측면에는 "＋" 또는 "－"의 드라이버 홈을 형성하여 사용자가 드라이버를 이용하여 회동시켜 조절토록 한다.On one side of the shaft 8, a driver groove of " + " or "-"

상기 캠(9)은 축봉(8)과 일체로 회동되며 그 캠(9)의 회동시 닥터블레이드(7)의 저면을 밀어서 닥터블레이드(7)를 상하강시켜 닥터갭(11)을 조정하도록 한다.The cam 9 is rotated integrally with the shaft 8, and when the cam 9 is rotated, the bottom of the doctor blade 7 is pushed up and down to lower the doctor blade 7 so as to adjust the doctor gap 11. .

상기 스프링(10)은 닥터블레이드(7)와 축봉(8)의 양단에 설치하여 탄력있게 상호 잡아당기도록 하므로써 닥터블레이드(7)를 캠(9)에 항상 접속되게 한다.The spring 10 is installed at both ends of the doctor blade 7 and the shaft rod 8 so that the doctor blade 7 is always connected to the cam 9 by elastically pulling each other.

미설명부호 12는 슬리브 구동기어이다.Reference numeral 12 is a sleeve drive gear.

이와같이 구성된 본 고안은 닥터갭(11)을 조정하고자 할때 축봉(8)을 드라이버를 이용하여 회동시키면 이와 일치로 된 캠(9)도 동시에 회동하게 되므로 그 캠(9)에 의하여 닥터블레이드(7)가 상하로 움직이게 된다.When the doctor gap 11 is to be adjusted, the present invention configured as described above rotates the shaft rod 8 with a driver so that the cam 9 is rotated at the same time so that the doctor blade 7 is rotated by the cam 9. ) Will move up and down.

이때 닥터갭(11)의 조정시 지그(도면에 미도시)를 닥터갭(11)에 끼운상태에서 축봉(8)을 회동시키면 손쉽게 조정할 수 있어 전문가가 아닌 사용자 누구든지 조정이 가능하므로 품질이 향상 및 신뢰도를 높힐수가 있는 것이다.At this time, when the doctor gap 11 is adjusted, the jig (not shown in the drawing) is inserted into the doctor gap 11, and the shaft 8 is rotated so that it can be easily adjusted. And can increase the reliability.

한편, 닥터블레이드(7)의 상하작동시 스프링(10)의 항상 탄력있게 잡아주고 있으므로, 닥터블레이드(7)가 유동되거나 닥터갭(11)의 변형이 없는 것이다.On the other hand, since the spring 10 is always elastically held in the vertical operation of the doctor blade 7, the doctor blade 7 is not flown or the deformation of the doctor gap (11).
