본 고안은 현상기의 착탈과 드럼 유니트에의 밀착, 분리를 용이하게 수행할수 있게 한 신규한 레이저 프린터의 현상기 착탈장치에 관한 것이다.The present invention relates to a developer detaching device for a novel laser printer that can easily attach and detach the developer and close and detach the drum unit.
레이저 프린터에 특히 적합한 구조를 갖고 있는 통상의 현상기 장착에 있어서는 (1)드럼과 현상기가 단일 카트리지형으로 이뤄진 것, (2)현상기를 옆방향으로 끼워넣고서 뒷쪽으로 부터 밀어 장착하는 것, (3)수납실에 마련된 홈에 현상기와 드럼을 끼워넣는 방식의 것 등이 있다.(1) The drum and the developer are of a single cartridge type, (2) the developer is inserted laterally and pushed from the rear, (3) And a type in which a developing machine and a drum are inserted into grooves provided in the storage chamber.
그러나, 상기 (1)의 경우에는 조작이 간편한 반면 단순한 이상이나 토너조달의 이유만으로 카트리지를 교환해야 하므로 유지비가 과대한 단점이 있고, (2)의 경우에는 현상기를 그 길이방향으로 삽입할때의 까다로움과 클램 쉘(clam shell)형에는 적용이 불가능한 단점이 있으며, (3)에 있어서는 현상기와 감광드럼과의 정격 간격 유지가 어려워서 현상 정밀도가 떨어지는 결점이 있다.However, in the case of (1), it is easy to operate, but the cartridge needs to be replaced only for the reason of simple toner or toner procurement, so there is an excessive maintenance cost. There are disadvantages in that it is not applicable to the difficulty and the clam shell type, and in (3) there is a drawback that the development accuracy is low because it is difficult to maintain the rated interval between the developer and the photosensitive drum.
본 고안은 현상기를 레버의 조작으로 간단하게 착탈시킬수 있고 또한 드럼과의 밀착 및 분리동작을 정확히 이뤄지게 하는 현상기 착탈장치를 제공하는데 그 목적을 둔 것으로서, 이하 첨부도면과 관련지어 구체적으로 설명한다.The present invention aims to provide a developer detaching device which can be easily detached by operation of a lever and precisely performs a close and detach operation with a drum. The present invention will be described in detail with reference to the accompanying drawings.
현상기 덮개(1)앞뒷면의 거의 복판에는 수납홈(2)이 형성되어 있다. 이 수납홈(2)은 위아래가 모두 열려있고, 일측면은 수직면(2a)을 이루지만 다른 면은 하향으로 경사지는 경사면(2b)을 이루고 있다. 따라서, 이 수납홈(2)은 위가 좁고 아래가 넓은 변형 사다리꼴을 이룬다. 이 수납홈(2)에는 레버(3)가 수용된다. 이 레버(3)에는 레버핀(4)과 안내판(5)이 형성되어 있으며, 레버핀(4)은 사이드 프레임(6)상의 호상안내공(7)에 끼워져 안내되므로 레버(4)가 선회활동시 안정을 유지할 수 있다.An accommodating groove 2 is formed in an almost double face of the front and back of the developer cover 1. The receiving groove 2 is open both up and down, and one side forms a vertical surface (2a), while the other surface forms an inclined surface (2b) inclined downward. Thus, the receiving groove 2 forms a deformed trapezoid with a narrow top and a wide bottom. The lever 3 is accommodated in this accommodating groove 2. The lever 3 is provided with a lever pin 4 and a guide plate 5, and the lever pin 4 is guided by being inserted into the arc guide hole 7 on the side frame 6, so that the lever 4 is pivoting. It can maintain stability.
또, 안내판(5)은 레버(3)가 선회운동할때 그 위에 얹힌 현상기를 승강시키는 역할을 하는 것이다. 이러한 구조를 갖춘 레버(3)는 축(8)을 통하여 기판(11)상의 브래킷(9)에 축으로 지지되며, 이 축(8)을 중심으로 제한된 각도 범위내에서는 선회활동이 가능한다.In addition, the guide plate 5 serves to raise and lower the developing device placed thereon when the lever 3 pivots. The lever 3 having such a structure is supported by the shaft 9 on the bracket 9 on the substrate 11 via the shaft 8, and is capable of turning within a limited angle range about the shaft 8.
그리고, 상기 축(8)에는 비틀림 코일 스프링(10)의 코일부가 끼워져 있으며, 상기 스프링(10)의 일단(10a)은 레버(3)의 내측에 그리고 타단(l0b)은 브래킷(9)의 대향측 내면에 각각 걸려 지지되어 있다. 브래킷(9)은 고정위치하므로 스프링(10)의 탄력은 레버(3)에 대하여 항상 현상기를 드럼에 밀착하는 자세를 취하도록 위치되는 방향으로 작용한다(제2도 참조).The coil 8 of the torsion coil spring 10 is fitted to the shaft 8, one end 10a of the spring 10 is inward of the lever 3 and the other end l0b is opposite to the bracket 9. It is hung on each side and is supported. Since the bracket 9 is in a fixed position, the elasticity of the spring 10 acts in the direction in which it is positioned so as to always be in close contact with the drum with respect to the lever 3 (see FIG. 2).
제2도에 도시한 바와같이 현상기(1)가 감광드럼(12)에 이격된 상태에서 레버(3)를 좌측으로 조작하면 레버(3)는 축(8)을 중심으로 회전하면서 레버(3)의 좌측 상단이 현상기(1)의 수납홈(2)의 경사면(2b)을 좌측으로 밀어주므로써 현상기는 좌측의 감광드럼(12)으로 근접하는 상태로 위치가 이동된다. 이때 안내핀(4)은 사이드 프레임(6)의 호상안내홈(7)에 안내되어져 안정되게 회전하며 이러한 동작은 레버(3)의 우측면 전체가 수납홈(2)의 우측 수직면(2a)에 완전히 닿는 순간에 멈춰진다(제3도 참조).As shown in FIG. 2, when the developing device 1 is operated by the lever 3 to the left while being spaced apart from the photosensitive drum 12, the lever 3 rotates about the shaft 8 while the lever 3 is rotated. The upper left side of the pusher pushes the inclined surface 2b of the accommodating groove 2 of the developing device 1 to the left side, and the developing device is moved to a state in which the developing device approaches the photosensitive drum 12 on the left side. At this time, the guide pin (4) is guided to the arc guide groove (7) of the side frame (6) to rotate stably, this operation is the entire right side of the lever (3) is completely on the right vertical surface (2a) of the receiving groove (2) It stops at the moment it touches (see Figure 3).
이후 현상기(1)를 감광드럼(12)측으로 부터 분리하고자 할 경우에는 레버(3)를 우측으로 조작하면 레버(3)는 축(8)을 중심으고 우측으로 회전하면서 레버(3)의 우측상단이 현상기(1)의 수납홈(2)의 수직면(2a)을 우측으로 밀어주므로써 현상기(1)는 좌측의 감광드럼(12)으로 부터 멀어지는 상태로 위치가 이동되며, 이러한 동작은 레버(3)의 좌측면이 수납홈(2)의 경사면(2b)에 완전히 닿는 상태까지 즉 제2도와 같은 상태가 될때까지 진행된다.Then, when the developer 1 is to be separated from the photosensitive drum 12 side, when the lever 3 is operated to the right, the lever 3 rotates to the right about the axis 8 and the upper right side of the lever 3. By pushing the vertical surface 2a of the receiving groove 2 of the developing device 1 to the right, the developing device 1 is moved away from the photosensitive drum 12 on the left side. 2) until the left side surface of the) is completely in contact with the inclined surface 2b of the receiving groove 2, that is, the state shown in FIG.
이와 함께 레버(3)의 하단 안내판(5)위에 얹혀 있는 현상기는 상기와 같은 분리동작과 동시에 약간 아래로 내려가 위치변동이 일어나서 상방에 여유공간이 확보되므로써 현상기를 들어낼 수가 있다.At the same time, the developing device mounted on the lower guide plate 5 of the lever 3 can be lowered slightly at the same time as the separating operation as described above, and the positional change occurs, thereby allowing the free space to be lifted up.
이상 설명한 대로 본 고안에 의하면 레버조작에 따라 현상기의 착탈과 동시에 드럼에의 밀착 및 분리가 다함께 달성할수 있는 것으로, 현상기의 착탈 및 밀착, 분리가 매우 간편하고 그 구조도 단순하여 다루기 쉬울뿐만 아니라 조작에 특별한 제한을 받지 않는데다가 조립능률도 높일 수 있고 사휴 보수유지도 한결 유리하다.According to the present invention as described above, according to the lever operation, the developer can be attached and detached at the same time as the lever is attached to and detached from the drum, and the developer can be easily attached to or detached from the developer. In addition, it is possible to increase assembly efficiency and maintain maintenance.
