본 고안은 복사기에 있어서, 현상기의 착탈시 현상기를 감광드럼과 밀착 해제시키기 위한 착탈장치에 관한 것이다.The present invention relates to a detachable device for releasing a developer from close contact with a photosensitive drum when attaching and detaching a developing device.

일반적으로 복사기에 있어서의 현상방식은 크게 2성분 현성방식과 1성분 현상방식으로 구별되고 있는데, 1성분 현상방식은 2성분 현상 방식에 비해 구조가 간단하고 가격이 저렴한 것 등의 장점 때문에 소형기에서 날로 그 사용이 증가하고 있는 상태이다.In general, the developing method of the copier is divided into two-component developing method and one-component developing method. The one-component developing method has a simple structure and low cost compared to the two-component developing method. Its use is increasing day by day.

그러나, 1성분 현상방식에 있어서는 2성분 현상방식에 비해 현상간격을 200-400㎛정도로 정밀하게 유지시켜야 하는 문제가 있다.However, in the one-component development method, there is a problem in that the development interval is precisely maintained at about 200-400 µm compared with the two-component development method.

현재 현상간격을 유지시키는 방법은 주로 현상슬리브 양단에 간격유지링을 설치하여 감광드럼과 간격 유지링과의 접촉 회전하는 방식을 사용, 간격 유지링과 현상슬리브와의 경의차에 의해 미세한 현상간격을 유지하고있는 실정으로 이 방식은 감광드럼이나 현상기의 취부시에 감광드럼 표면에 손상이 발생할 우려가 크므로 현상기를 필요에 따라 감광드럼과 착탈시키는 장치가 필요한 것이다.Currently, the method of maintaining the development gap is mainly provided with a gap retaining ring at both ends of the developing sleeve to rotate the contact between the photosensitive drum and the gap retaining ring. In this situation, there is a high possibility that the surface of the photosensitive drum may be damaged when the photosensitive drum or the developer is mounted, and thus, a device for attaching and detaching the photosensitive drum as necessary is required.

종래의 방식은 주로 현상기 외부에 스프링이나 캠을 설치하여 현상기를 회전시키거나 미는 방법에 의하여 감광드럼과 현상기의 착탈을 행하는 방법을 채택하고 있어서 복사기의 본체의 형상을 복잡하게 하는 단점이 있었다.The conventional method mainly adopts a method of attaching and detaching the photosensitive drum and the developer by rotating or pushing the developer by installing a spring or a cam outside the developer, thereby complicating the shape of the main body of the copier.

본 발명은 상기와 같은 종래의 제결함을 감안하여 현상기 자체에 캠 및 회전손잡이를 장착하여 외부벽을 미는 방법에 의하여 감광드럼과 현상기의 착탈을 행하도록 된 간단한 구조로 복사기 본체의 형상을 간단하게 함과 동시에 감광드럼의 손상을 미연에 방지할 수 있도록 안출한 것로 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention is simple in shape of the copier main body with a simple structure to attach and detach the photosensitive drum and the developer by a method of pushing the outer wall by mounting the cam and the rotary knob to the developer itself in view of the above conventional defects. At the same time, to prevent damage to the photosensitive drum in advance to be described in detail according to the accompanying drawings as follows.

감광드럼(1)을 사용하고 간격 유지링(13)에 의해 현상간격을 유지하는 복사기의 현상장치에 있어서 제3도 및 제4도에 도시한 바와 같이 현상기(2) 자체에 회동축 (6)으로 연결된 착탈캠(4)과 회전손잡이(5)를 설치하여 상기 착탈캠(4)이 회동으로 감광드럼(1)과 현상기(2)의 현상슬리브(3)가 착탈 가능토록 한 것으로, 즉, 착탈캠(4)이 외부벽(7)과 하부에 돌설된 지지대(8)를 미는 동작에 의하여 감광드럼(1)과 현상기 (2)의 착탈동작이 이루어지며, 상기 회전손잡이(5)에 축설된 회동축(6)의 일단에는 스프링(11) 및 스프링지지링(12)을 삽설하여 회전손잡이(5)가 현상기(2)의 측벽에 설치된 고정핀(9)(10)에 고정되도록 구성되어 있다.In the developing apparatus of the copier, which uses the photosensitive drum 1 and maintains the developing interval by the spacing retaining ring 13, as shown in FIGS. 3 and 4, the rotating shaft 6 is formed on the developing unit 2 itself. Detachable cam (4) and the rotary knob (5) connected to the installation by the detachable cam (4) is rotated so that the developing sleeve (3) of the photosensitive drum (1) and the developer (2), that is, Detachable operation of the photosensitive drum 1 and the developer 2 is performed by pushing the detachable cam 4 against the outer wall 7 and the support 8 protruding from the lower part. One end of the rotating shaft 6 is inserted into the spring 11 and the spring support ring 12 is configured to be fixed to the fixing pins (9) (10) installed on the side wall of the developing knob (2) have.

이와 같이 구성된 본 고안의 작용효과를 설명하면, 제1도는 본 고안의 정면 개략도를 나타낸 것으로 감광드럼(1)에 현상기(2)의 현상 슬리브(3)를 접동시켜 현상을 행할시에는 제2b도와 같이 현상기(2)에 축설된 착탈캠(4)을 회전손잡이(5)를 이용하여 시계 반대방향으로 회전시키게 되면 현상기(2)가 복사기 본체의 외부벽(7)에 의하여 좌방향(감광드럼(1)쪽)으로 밀리면서 제1a도 및 제4도에서 보는 바와 같이 감공드럼 (1)에 현상기(2)의 현상슬리브(3)가 접동되어 현상이 설치되는 것이다.Referring to the operation and effect of the present invention configured as described above, FIG. 1 shows a schematic front view of the present invention. Likewise, when the detachable cam 4 arranged in the developing unit 2 is rotated counterclockwise by using the rotary knob 5, the developing unit 2 is moved to the left side by the outer wall 7 of the copier main body (photosensitive drum ( 1), as shown in FIGS. 1A and 4, the developing sleeve 3 of the developing device 2 is slid to the vaccinating drum 1 so that the developing is installed.

(실제로는 간격유지링(13)에 의하여 감광드럼(1)과 현상 슬리브(3)는 미세한 간격이 유지됨)(Actually, the gap between the photosensitive drum 1 and the developing sleeve 3 is maintained by the gap retaining ring 13).

즉, 착탈캠(4)과 동축상에 연결된 회전손잡이(5)를 제3b도와 같이 당기게 되면 회동축(6)에 탄설된 스프링(11)이 압축되면서 회전손잡이(5)는 현상기(2)의 측벽에 돌설된 고정핀(9)에서 이탈되게 되므로 회전손잡이(5)를 제3a도와 같이 회전시키게 되면 현상기(2)는 좌방향으로 이동(여기서 현상기(2)의 이동거리는 착탈캠(4)이 형상에 의하여 임의 조정이 가능하다)되고, 이때 회전손잡이(5)를 놓게 되면 스프링 (11)의 복원탄력에 의하여 회전손잡이(5)가 고정핀(10)에 록크되는 것이다.That is, when pulling the rotary knob (5) coaxially with the removable cam (4) as shown in 3b, the spring 11, which is installed on the rotating shaft (6) is compressed and the rotary knob (5) of the developer (2) Since the fixing pin 9 protrudes from the side wall, the rotating knob 5 rotates as shown in FIG. 3a, and the developing unit 2 moves to the left (where the moving distance of the developing unit 2 is a detachable cam 4). Can be arbitrarily adjusted according to the shape), and when the rotary knob 5 is released, the rotary knob 5 is locked to the fixing pin 10 by the restoring elasticity of the spring 11.

한편, 복사기에서 현상기(22)를 분리하고자 할 경우에는 제2b도의 상태에서 a도와 같이 착탈캠(4)을 시계방향으로 회전시키게 되면 착탈캠(4)의 선단부가 하부에 돌설된 지지대(8)를 밀게 되므로 현상기(2)가 우측으로 당겨지면서 감광드럼(1)에서 현상슬리브(3)가 분리되는 것으로 현상기(2)의 취부동작시 감광드럼(1)을 손상시키지 않고 용이하게 현상기(2)를 취부할 수가 있게 되는 것이다.On the other hand, when the developer 22 is to be removed from the copier, the support cam 8 protrudes from the lower end of the detachable cam 4 when the detachable cam 4 is rotated clockwise as shown in FIG. Since the developer 2 is pulled to the right, the developing sleeve 3 is separated from the photosensitive drum 1, so that the developer 2 is easily damaged without damaging the photosensitive drum 1 during the mounting operation of the developer 2. Will be able to mount.

즉, 감광드럼(1)에 현상기(2)의 현상슬리브(3)가 밀착되어 있는 현상 상태에서 현상기(2)를 분리시키고자할 경우에는 전기한 바와 같이 먼저 회동축(6)에 일체적으로 설치된 회전손잡이(5)를 앞쪽으로 당겨서 고정핀(9)에서 회전손잡이(5)를 해제시킨 다음, 이를 시계방향으로 회전시킨다.That is, when the developer 2 is to be separated in the developing state in which the developing sleeve 3 of the developing device 2 is in close contact with the photosensitive drum 1, first, as described above, the integrated shaft 6 is integrally formed. Pull the installed rotary knob 5 forward to release the rotary knob 5 from the fixing pin 9, and then rotate it clockwise.

그러면, 상기 회동축(6)에 고정 설치되어 있는 착탈캠(4)이 함께 회전하는 과정에서 그 하단에 돌출 설치되어 있는 지지대(8)에 걸리게 되므로 결국 현상기(2) 전체가 우측으로 이동을 하게 되어 감광드럼(1)과 현상슬리브(3)가 분리됨으로써 현상기(2)의 취부동작시 고가의 감광드럼(1)의 손상을 미연에 방지할 수가 있는 것이다.Then, in the process of rotating the removable cam (4) fixed to the rotation shaft (6) is caught by the support (8) protrudingly installed at the lower end so that the entire developing unit (2) is moved to the right. Thus, the photosensitive drum 1 and the developing sleeve 3 are separated, thereby preventing damage to the expensive photosensitive drum 1 during the mounting operation of the developing device 2.

이와 같이 본 고안은 현상기 자체에 착탈캠 및 회전손잡이를 장착하여 외부벽을 미는 방법으로 현상기의 착탈장치를 구성함으로써 복사기의 형상을 간단하게 하고 현상기의 취부시 감광드럼의 손상을 방지할수 있는 그 실사용 가치가 일층 고양된 신규의 고안인 것이다.As such, the present invention simplifies the shape of the copier and prevents damage to the photosensitive drum when the developer is installed by constructing the detachable device of the developer by attaching the detachable cam and the rotary knob to the developing device by pushing the outer wall. It is a novel design that is further enhanced in its use value.
