본 고안은 전자사진 복사기의 현상기 장, 탈착 장치에 관한 것으로서 특히, 드럼에 대한 현상기의 착탈이 정확히 이루어지고 본체로부터 현상기를 안전하게 분해 조립할 수 있도록 개량한 현상기 장, 탈착장치에 관한 것이다.The present invention relates to a developing device field and a detaching device of an electrophotographic photocopier, and more particularly, to a developing device field and a detaching device improved so that the detachment of the developing device to the drum can be made accurately and safely assembled and disassembled from the main body.
종래에 복사기의 현상기 장탈착 장치에서는 현상기 홀더 후방에 별도의 회동장치를 설치하여 현상기를 현상기 홀더에 장착한 후 회동장치를 작동하였다.Conventionally, in the developing device for attaching and detaching a copying machine, a separate rotating device is installed at the rear of the developing holder, the developer is mounted on the developing holder, and then the rotating device is operated.
상기와 같은 장치는 현상기 홀더의 후방에 별도의 회동장치를 설치하여 현상기 홀더에 현상기를 장착후 회동장치를 조작하므로서 현상기의 마그네트롤과 드럼표면이 일정거리를 유지하도록 드럼쪽으로 움직이고, 분리시에는 장착할때와 반대로 회동장치를 작동시켜서 현상기 홀더가 감광 드럼과 멀어지도록 하였다.The above-described apparatus installs a separate rotating device on the rear of the developing holder, and installs the developing device in the developing holder, and then operates the rotating device to move the developing unit to the drum to maintain a certain distance between the magnetotrol and the drum surface. Conversely, the rotating device was operated so that the developer holder was moved away from the photosensitive drum.
이러한 종래의 현상기 착탈 장치는 현상기 홀더 후방에 별도의 회동장치를 설치해야 하므로 현상기 착탈장치 구조가 대형화하여 원가가 높을 뿐 아니라 가공, 조립 고정에 어려운 문제점이 많았다.Such a conventional developer detaching device has to install a separate rotating device in the rear of the developer holder, so that the structure of the developing device detaching device is enlarged, so that the cost is high and the processing and assembly fixing are difficult.
본 고안은 상기와 같은 문제점을 보완하기 위하여 안출된 것으로서 드럼에 대한 현상기의 분리 및 접촉이 정확히 이루어지도록 하며 간단한 록킹 장치에 의해 정확하고 손쉽게 현상기를 드럼에 착탈시킬 수 있도록 하며, 구조를 단순화하고 소형화 하므로써 제작이 용이하게 하고 원가를 절감하고 화질의 저하를 방지할 수 있도록 하는데 본 고안의 목적이 있다.The present invention has been devised to solve the above problems, and the separation and contact of the developer to the drum is made accurately, and the simple locking device allows the developer to be detached from the drum accurately and easily, simplifying the structure and miniaturizing it. The purpose of the present invention is to facilitate the production, to reduce the cost and to prevent the degradation of the image quality.
상기와 같은 목적을 달성하기 위한 실시예를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.An embodiment for achieving the above object will be described in detail with reference to the accompanying drawings.
감광드럼(1)의 일측에 착설되며 타측에 현상기(6)를 수용하는 현상기 홀더(7)는 상부가 축(3)에 의해 회동가능토록 지지되며, 하부의 놉(5)에는 외측방향으로 탄지하는 스프링(4)이 탄지됨과 동시에 상기 현상기 홀더(7) 하부에 일체로된 놉(5)을 고정시키기 위한 잠금장치(20)를 구비하고, 상기 잠금장치(20)는 전면판넬(2) 후면에 하측이 고정된 판스프링(8)의 끝부분에 설치되어 탄지되는 핀(10)이 놉(5) 전면구멍(11)에 삽입될 수 있도록 하며, 전면판넬(2)에 스프링(4')으로 탄지되는 놉(9)의 끝단(9')의 상기 판스프링(8)의 중간부위에 접촉하도록 하여서 된 것으로서 도면중 미설명 부호 6은 현상기, 12는 스페이서, 13은 마그네트 롤러, 14는 판스프링을 고정하기 위한 리벳이며 15는 E링이다.The developer holder 7 installed on one side of the photosensitive drum 1 and accommodating the developer 6 on the other side thereof is supported by the shaft 3 to allow the upper part to be rotatable, and to the outside of the knob 5 on the lower side. And a locking device 20 for fixing the knob 5 integrated under the developer holder 7 at the same time as the spring 4 is supported, and the locking device 20 is provided at the rear of the front panel 2. The pin 10, which is installed at the end of the leaf spring 8 fixed to the lower side, can be inserted into the front hole 11 of the knob 5, and the spring 4 'on the front panel 2. In this figure, reference numeral 6 denotes a developer, 12 denotes a spacer, 13 denotes a magnet roller, and 14 denotes a plate in contact with an intermediate portion of the leaf spring 8 of the end 9 'of the knob 9. Rivets for fixing the spring, 15 is the E-ring.
상기와 같이 구성된 본 고안의 작용 효과는 다음과 같다.Effects of the present invention configured as described above are as follows.
우선 현상기를 기기 본체에 장착시킬때에는 현상기(6)를 현상기홀더(7)에 삽입하면 현상기 홀더(7)는 측면의 스프링(4) 탄력에 의하여 감광드럼(1)으로부터 이격된 위치에 있게 된다.First, when the developer is mounted on the apparatus main body, the developer 6 is inserted into the developer holder 7 so that the developer holder 7 is located at a position spaced apart from the photosensitive drum 1 by the elasticity of the spring 4 on the side.
이후 하단의 놉(5)을 잡고 시계방향으로 회전시키면 현상기홀더(7)는 축(3)을 중심으로 회전하게 되어 현상기(6) 내부에 설치된 마그네트 롤러(13) 양단에 설치된 스페이서(12)가 감광드럼(1)의 양단에 접촉하면서 마그네트 롤러(13)와 감광드럼(1) 사이의 거리를 일정하게 유지하게 된다. 이때 현상기 홀더(7)를 고정시키기 위하여 최초에는 전면 판넬(2) 후측에 설치된 판스프링(8) 끝부분에 설치된 핀(10)은 현상기(7) 하부에 일체로된 놉(5)의 후면(5')에 접촉하고 있던 상태에서 현상기 홀더(7)가 회전함에 따라 놉(5)에 형성된 구멍(11)이 이동하면서 핀(10)의 위치와 일치하는 순간 핀(10)은 판스프링(8)의 탄력에 의해서 전면으로 돌출되면서 놉(5)의 구멍(11)에 끼워져 현상기홀더(7)가 유동하지 못하도록 고정하게 된다.After holding the knob 5 at the bottom and rotating it clockwise, the developer holder 7 rotates about the shaft 3 so that the spacers 12 provided at both ends of the magnet roller 13 installed inside the developer 6 The distance between the magnet roller 13 and the photosensitive drum 1 is kept constant while contacting both ends of the photosensitive drum 1. At this time, in order to fix the developer holder (7), the pin (10) at the end of the leaf spring (8) installed at the rear of the front panel (2) is the rear of the knob (5) integrally under the developer (7) 5 '), as the developer holder 7 rotates while the hole 11 formed in the knob 5 is moved to coincide with the position of the pin 10, the pin 10 is moved to the leaf spring (8). Protruding to the front by the elasticity of the () is inserted into the hole 11 of the knob 5 is fixed so as not to flow the developer holder (7).
이와 같은 상태에서 인쇄 작업을 수행하게 되며 필요에 따라 현상기를 분리하고자 할 경우에는 전면판넬(2)에 설치된 놉(9)을 눌러주게 되면 놉(9)의 끝단(9')이 판스프링(8)의 중간부를 눌러주게 되어 판스프링(8)이 뒤로 밀려나게 된다. 이때 핀(10)은 스프링(4")의 탄력에 의해 뒤로 밀리면서 놉(5)의 구멍(11)을 벗어나는 순간 인장 스프링(4)에 의해 현상기홀더(7)가 감광드럼(1)으로부터 멀어지려는 방향으로 축(3)을 중심으로 회전한다.In this state, the printing operation is performed, and if necessary, to remove the developer, if the knob 9 installed on the front panel 2 is pressed, the end 9 'of the knob 9 becomes the leaf spring (8). Press the middle part of the) and the leaf spring 8 is pushed back. At this time, the pin holder 10 is pushed back by the elasticity of the spring 4 "and the developer holder 7 is moved away from the photosensitive drum 1 by the tension spring 4 at the time of leaving the hole 11 of the knob 5. Rotate around the axis 3 in the direction to be built.
즉 제3도와 같이 감광드럼(1)과 현상기(6)가 이격되어지므로 현상기(6)을 전면으로 분리시키더라도 감광드럼(1)에 손상을 주지 않게 된다.That is, since the photosensitive drum 1 and the developer 6 are spaced apart as shown in FIG. 3, the photosensitive drum 1 is not damaged even when the developer 6 is separated to the front.
상기한 바와 같이 본 고안에 의하면 간단한 구성에 의하여 현상기를 감광드럼과 정확한 간격을 유지시킬 수 있도록 함과 동시에 분리시에는 감광드럼을 손상시키지 않도록 하므로 기기의 신뢰성을 향상시킬 수 있으며 기기를 소형화시킬 수 있게 된다.As described above, according to the present invention, it is possible to maintain the accurate distance from the photosensitive drum by a simple configuration and not to damage the photosensitive drum upon separation, thereby improving the reliability of the device and miniaturizing the device. Will be.
