본 고안은 레이저 프린터에 있어서, 감광체 및 현상기의 착탈장치에 관한 것으로, 특히 감광체 및 현상기의 착탈을 용이하게 하여 사용자에게 편의를 제공한 레이저 프린터의 감광체 및 현상기 착탈장치에 관한 것이다.The present invention relates to a detachable device for a photosensitive member and a developer in a laser printer, and more particularly, to a photosensitive member and a developer detachable device for a laser printer that provides convenience to a user by easily attaching and detaching the photosensitive member and a developer.

일반적으로 레이저 프린터는 제1도에 도시한 바와같이, 기기본체(21)가 상.하체(22)(23)로 분리되는 분리형 레이저 프린터가 사용되는 바, 이와같은 상.하체(22)(23) 분리형 레이저 프린터는 감광체(24)의 수리, 교환 청소등을 위하여 하체(23)에 결합된 상체(22)를 분리하는 경우에는 제1도에 가상선으로 도시한 바와같이, 상체(22)를 블어올리고, 감광체 축(25)을 빼낸 다음에 감광체(24)를 화살표의 방향으로 분리시켰으며, 또한 감광체(24)를 결합시킬 경우에는 감광체(24)를 화살표의 반대 방향으로 삽입한 후에 감광체축(25)을 끼우고, 상체(22)를 하측(23)에 결합시켰다.In general, as shown in FIG. 1, a separate type laser printer is used in which the apparatus main body 21 is separated into upper and lower bodies 22 and 23, and thus the upper and lower bodies 22 and 23 are used. When the detachable laser printer separates the upper body 22 coupled to the lower body 23 for repair, replacement, and the like of the photosensitive member 24, the upper body 22 is shown as a virtual line in FIG. The photoconductor shaft 25 is pulled up, the photoconductor shaft 25 is removed, and the photoconductor 24 is separated in the direction of the arrow. In addition, when the photoconductor 24 is coupled, the photoconductor 24 is inserted in the opposite direction to the arrow, and then the photoconductor shaft (25) was fitted and the upper body 22 was connected to the lower side 23. As shown in FIG.

그리고 토너의 공급은 레이저 프린터 본체의 상측방향에서 공급하도록 되어 있다.The toner is supplied from the upper side of the laser printer main body.

그러나, 이와같은 일반적인 레이저 프린터는 청소장치, 대전기, 제전기둥이 일체로 고정되어 있지 않으므로 감광체(24)의 교환이 용이하지 못한 문제점이 있었으며, 또한 감광체(24) 및 현상기(26)를 카트리지화하여 사용한다할지라도 토너의 공급이 기기본체(21)이 상측에서 이루어지므로, 20PPM의 중속레이저 프린터의 경우에는 한달에 두 번정도 감광체(24) 및 현상기(26)의 카트리지를 분리시켜야 하는 불편함이 있었다.However, such a general laser printer has a problem that the replacement of the photoconductor 24 is not easy because the cleaning device, the charger, and the eliminator are not fixed together, and the photoconductor 24 and the developer 26 are cartridgeized. Even if the toner is supplied, the main body 21 is supplied from the upper side, so in the case of a 20PPM medium speed laser printer, it is inconvenient to separate the cartridges of the photosensitive member 24 and the developer 26 twice a month. There was this.

본 고안은 이와같은 종래의 문제점을 해소하기 위하여 안출한 것으로, 기기본체의 측면 프레임에 탄성고정부를 구비한 고정편을 고정하여 상기 탄성고정부에 현상기의 고정핀을 삽입되게 함으로써 현상기의 착탈을 용이하게할 수 있게한 동시에 감광체, 청소장치, 대전기, 제전기를 일체로 고정함으로써 감광체의 교환, 수리 청소를 용이하게할 수 있도록 구성한 것인 바, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is devised to solve such a conventional problem, by fixing the fixing piece having an elastic fixing to the side frame of the main body of the device by inserting the fixing pin of the developing device to the elastic fixing unit to remove the developer. At the same time, the photosensitive member, the cleaning device, the charger, and the static eliminator are integrally fixed so as to facilitate the replacement and repair of the photosensitive member. same.

제2도 내지 제4도에 도시한 바와같이, 레이저 프린터에 있어서, 기기본체(1)의 내측부 일정부위에 걸림턱(2a)(2′a)을 갖는 ㄴ자상 안내돌조(2)(2′)를 고정하여 감광체(3)와 청소장치(4)와 대전기(5)와 제전기(6)를 일체로 고정한 감광체 카트리지(7)를 고정하고, 상측부에 회동가능한 덮개(8)를 갖는 현상기(9)의 양측부에는 고정핀(9a)을 돌출 형성하며 상기 기기본체(1)의 측면프레임(1a) 일정부위에는 상기 고정핀(9a)의 직경보다 작은 입구폭(a)을 갖는 탄성 고정부(10a)를 구비한 고정편(10)를 나사(11)(11′)로 고정함과 아울러 상기 현상기(9)의 하축부에는 착탈캠(12)을 설치하며, 상기 현상기(9)의 일측부에는 현상기(9)를 일정한 힘으로 탄력지지하는 스프링(13)을 고정하고, 상기 기기본체(1)의 상면에는 회전가능한 덮개(14)를 복개하여 구성한 것이다.As shown in Figs. 2 to 4, in the laser printer, the B-shaped guide protrusions 2 (2 ') having locking jaws 2a (2'a) at a predetermined portion of the inner part of the main assembly 1 of the machine body 1 are shown. ) To fix the photosensitive member (3), the cleaning device (4), the photosensitive member cartridge (7) in which the charger (5) and the static eliminator (6) are integrally fixed, and having a cover (8) rotatable on the upper side thereof. Fixing pins (9a) protruding on both sides of the developing device (9) and the elastic part having an inlet width (a) smaller than the diameter of the fixing pin (9a) in a predetermined portion of the side frame (1a) of the device body (1) The fixing piece 10 having the fixing portion 10a is fixed with screws 11 and 11 ', and a detachable cam 12 is installed at the lower shaft of the developing unit 9, and the developing unit 9 is provided. On one side of is fixed to the spring 13 for elastically supporting the developing device 9 with a constant force, the upper surface of the device body (1) is configured to cover the rotatable cover (14).

이와같은 구성을 갖는 본 고안 레이저 프린터의 감광체 및 현상기 착탈장치의 작용, 효과를 제2도 내지 제4도를 참고하여 설명하면 다음과 같다.The operation and effects of the photoconductor and the developer detaching device of the present invention laser printer having such a configuration will be described with reference to FIGS. 2 to 4 as follows.

우선, 현상기(9)를 고정하는 경우에는 기기본체(1)의 상면덮개(14)를 열고 측면 프레임(1a)의 고정편(10)에 구비된 탄성고정부(10a)에 현상기(9)의 고정핀(9a)을 삽입하게 되면, 탄성고정부(10a)의 입구폭(a)은 고정핀(9a)의 직경보다 작으므로 탄성고정부(10a)는 약간 벌어지면서 현상기(9)의 고정핀(9a)이 삽입되며, 고정핀(9a)의 삽입이 완료되면 탄성고정부(10a)는 탄성복원력에 의하여 오므라들면서 고정핀(9a)의 이탈을 방지하게 된다.First, in the case of fixing the developing device 9, the top cover 14 of the apparatus main body 1 is opened and the elastic fixing part 10a provided in the fixing piece 10 of the side frame 1a of the developing device 9 When the fixing pin (9a) is inserted, the inlet width (a) of the elastic fixing portion (10a) is smaller than the diameter of the fixing pin (9a), so that the elastic fixing portion (10a) slightly open the fixing pin of the developing device (9) 9a is inserted, and when the fixing pin 9a is inserted, the elastic fixing unit 10a is retracted by the elastic restoring force to prevent the fixing pin 9a from being separated.

또한 현상기(9)를 분리할 경우에는 현상기(9)를 상측으로 잡아당기면 탄성고정부(10a)는 현상기(9)의 고정핀(9a)에 의하여 약간벌어지게 되고 현상기(9)의 고정핀(9a)이 탄성고정부(10a)에서 완전히 벗어나게 되면 탄성고정부(10a)는 탄성복원력에 의하여 원래의 형상으로 오므라들게 된다.In addition, when the developer 9 is removed, when the developer 9 is pulled upward, the elastic fixing part 10a is slightly opened by the fixing pin 9a of the developer 9 and the fixing pin of the developer 9 ( When 9a) is completely out of the elastic fixing part 10a, the elastic fixing part 10a is retracted to its original shape by the elastic restoring force.

상기한 바와같이 현상기(9)가 고정핀(9a)에 의하여 고정된 상태에서 감광체(3)의 수리, 교환, 청소등을 위하여 감광체(3)를 들어내고자할 경우에는 착탈캠(12)을 회전시키게 되면 현상기(9)는 고정핀(9a)을 중심으로 반시계 방향으로 회동하여 감광체(3)와 떨어지게 되며, 이와같이 현상기(9)가 감광체(3)로부터 떨어진 다음 아내돌조(2)(2′)의 걸림턱(2a)(2′a)에 얹혀진 감광체 카트리지(7)를 들어내면 청소장치(4), 대전기(5), 제전기(6)등과 일체로 고정된 감광체(3)를 들어낼 수 있다.As described above, when the developer 9 is lifted by the fixing pin 9a to rotate the photosensitive member 3 for repair, replacement, or cleaning of the photosensitive member 3, the detachable cam 12 is rotated. When the developer 9 is rotated counterclockwise around the fixing pin 9a, the developer 9 is separated from the photoconductor 3. Thus, the developer 9 is separated from the photoconductor 3, and then the wife protrusions 2 and 2 'are removed. Lifting the photosensitive member cartridge 7 mounted on the latching jaw 2a (2'a) of the upper side, lifts the photosensitive member 3 fixed integrally with the cleaning apparatus 4, the charger 5, the electrostatic eliminator 6, and the like. I can make it.

또한, 반대로 감광체(3)를 고정할 경우에는 현상기(9)가 고정핀(9a)을 중심으로 반시계 방향으로 회전된 상태에서 감광체(3)가 고정된 감광체 카트리지(7)를 밀어넣어 안내돌조(2)(2′a)에 안착시키면 되고, 감광체 카트리지(7)와 안착된 후에 현상기(9)를 시계방향으로 회동시키면 스프링(13)의 탄력이 현상기(9)의 일축에 가해지게 되어 현상기(9)의 유동을 방지하게 된다.On the contrary, in the case where the photoconductor 3 is fixed, the guide protrusion is pushed by pushing the photoconductor cartridge 7 on which the photoconductor 3 is fixed while the developing unit 9 is rotated counterclockwise around the fixing pin 9a. (2) (2'a), and when it is seated with the photoconductor cartridge (7), when the developer (9) is rotated clockwise, the elasticity of the spring (13) is applied to one axis of the developer (9). (9) prevents the flow.

그리고 토너의 공급에 있어서는, 기기본체(1)의 상면에 부착된 상면덮개(14)와 현상기(9)의 덮개(8)를 열고 토너를 공급할 수 있다.In the supply of the toner, the top cover 14 attached to the top surface of the apparatus main body 1 and the cover 8 of the developer 9 can be opened to supply the toner.

이상에서 설명한 바와같은 본 고안 레이저 프린터의 감광체 및 현상기 착탈장치는 감광체, 청소장치, 대전기, 제전기를 일체로 고정함으로써 감광체의 수리, 교환, 청소를 용이하게 할 수 있으며, 3개월 내지 6개월마다 한번씩 하게되는 토너의 공급도 기기본체의 상측에서 덮개만 열게되면 가능하게 되어 사용자에게 편의 제공하는 효과가 있게 된다.As described above, the photosensitive member and the developer detaching device of the inventive laser printer can easily repair, replace and clean the photosensitive member by fixing the photosensitive member, the cleaning device, the charger, and the static eliminator integrally. The supply of the toner, which is performed once every time, is also possible when only the cover is opened on the upper side of the apparatus body, thereby providing convenience to the user.
