본 고안은 화상형성장치의 전사용지 안내구의 관한 것으로 특히, 용수철의 탄성력을 이용하여 전사되는 복사용지에 균일한 힘을 작용시켜 토너상을 안정하게 이동시키도록 된 화상형성장치의 전사용지 안내구에 관한 것이다.The present invention relates to a transfer paper guide of an image forming apparatus, and more particularly, to a transfer paper guide of an image forming apparatus which stably moves a toner image by applying a uniform force to a copy paper to be transferred using an elastic force of a spring. It is about.
종래 화상형성장치 일예로, 복사기에 있어서, 감광드럼을 이용하여 복사용지에 토너(TONER)를 전사시키는 전사공정은 감광드럼에 부착된 토너를 전사기를 사용해 용지에 이동시킴으로써 사용자가 원하는 글자나 그림을 용지에 새기는 중요한 공정이다. 특히 복사기(PPC)나 레이저빔 프린더(LBP)에서 전사효율이 좋은 복사를 하기 위해서는 용지가 정전전사 영역에 진입하는 직전에 감광드럼과 용지와의 밀착력을 증가시켜 감광드럼에 있는 토너를 원하는 위치에 정확히 전사하여야 하는바, 종래의 복사기에서 사용되어 있는 전사용지 안내구는 제1도에 도시된 바와같이 감광드럼(1)의 하부에 전사용지 지지부재(13)가 설치되어 있었고, 이 상하로 움직일 수 없도록 위치가 고정된 지지부재(13)에 의해 용지(5)가 감광드럼(1)에 밀착하게 되어 있었다.In an example of a conventional image forming apparatus, in a copying machine, a transfer process of transferring a toner to a copy paper by using a photosensitive drum moves a toner attached to the photosensitive drum onto a sheet of paper by using a transfer machine to transfer letters or pictures desired by a user. Engraving on paper is an important process. In particular, in order to make good copying efficiency in the copier (PPC) or laser beam printer (LBP), the toner in the photosensitive drum is increased by increasing the adhesion between the photosensitive drum and the paper just before the paper enters the electrostatic transfer area. The transfer paper guide used in the conventional copier has a transfer paper support member 13 installed on the lower part of the photosensitive drum 1, as shown in FIG. The paper 5 was in close contact with the photosensitive drum 1 by the support member 13 whose position was fixed so that it could not be.
그런데, 이러한 종래의 전사용지 안내구는 상기 지지부재(13)가 상하로 움질일 수 없도록 위치가 고정됨으로 인해 드럼(1)과 전사용지 지지부재(13)사이의 간격이 고정되게 되며 따라서 용지(5)의 두께가 얇을 경우, 용지(5)의 드럼에 대한 밀착력이 좋지 않아 용지에 형성되는 화상의 흩어짐 현상이 나타날 수 있는 문제점이 있었고, 용지의 두께가 두꺼울 경우에는 용지의 드럼에 대한 과다한 밀착력으로 인해 드럼의 손상이 발생되는 문제점이 있었으며, 토너의 전사후에는 드럼(1)과 용지(5)의 분리가 좋지 않아서 용지의 걸림이 발생되거나, 용지가 올바른 경로로 이동을 하지 못하고, 용지가 진동됨으로 인해서 용지에 전사된 토너가 이동하여 용지의 이면이 오염될 확률이 높았으며 드럼(1)에 강압 압력이 가해짐에 따라 드럼의 구동계에 과부하가 걸리게 되는 문제점이 있었다.However, in the conventional transfer paper guide, the distance between the drum 1 and the transfer paper support member 13 is fixed because the position is fixed so that the support member 13 cannot be moved up and down. ), When the thickness of the sheet is thin, the adhesion of the paper 5 to the drum is not good, and there is a problem that an image scattering phenomenon may occur on the paper. If the thickness of the paper is thick, the paper may be excessively adhered to the drum. There was a problem that the drum is damaged due to, the separation of the drum (1) and the paper (5) is not good after the transfer of the toner, a paper jam occurs, the paper does not move in the correct path, the paper vibrates As a result, the toner transferred to the paper moved and the back surface of the paper was more likely to be contaminated. As the stepping pressure was applied to the drum 1, the drum drive system was overloaded. There was a problem.
이에 본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 용수철의 신장력과 수축력을 이용하여 전사되는 복사용지에 균일한 힘을 작용시키도록 된 화상형성장치의 전사용지 안내구를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, to provide a transfer paper guide of the image forming apparatus to apply a uniform force to the copy paper to be transferred by using the stretching force and contraction force of the spring. There is this.
이하 예시된 도면에 의거 본 고안의 구성 및 작용효과를 상세히 설명한다.Hereinafter, the configuration and the effect of the present invention will be described in detail based on the illustrated drawings.
본 고안은 화상형성장치의 전사용지 안내구에 있어서, 용지에 토너를 전사시키는데 사용되는 감광드럼(1)의 하부에는 밀착고무로울러(2)가 설치되고 이 로울러(2)의 하부에는 지지부재(3)가 설치되며, 이 지지부재(3)의 일단에는 브라켓(4)에 고정된 용수철(6)이 설치되어져서 용지(5)의 두께가 변동되더라도 감광드럼(1)과 로울러(2)사이를 이동하는 용지(5)가 일정한 압력을 받으면서 이송될 수 있도록 된 화상형성장치의 전사용지 안내구이다.According to the present invention, in the transfer paper guide of the image forming apparatus, a close contact rubber roller (2) is installed at the lower part of the photosensitive drum (1) used to transfer the toner to the paper, and at the lower part of the roller (2), a supporting member ( 3) is installed, and a spring 6 fixed to the bracket 4 is installed at one end of the support member 3 so that even if the thickness of the paper 5 is varied, between the photosensitive drum 1 and the roller 2, It is a transfer paper guide of the image forming apparatus that the paper 5 for moving the paper 5 can be conveyed under a constant pressure.
상기와 같이 이루어진 본 고안에 따른 전사용지 안내구는 상기 로울러(2)가 탄성을 가지면서 상하로 이동가능하기 때문에, 용지(5)의 두께가 가변되어도 감광드럼(1)에 손상이 입혀지지 않고 용지(5)가 순조로운 이동을 할 수 있게 된다.Transfer paper guide according to the present invention made as described above because the roller (2) is movable up and down while having elasticity, even if the thickness of the paper (5) is variable does not damage the photosensitive drum (1) (5) will be able to move smoothly.
제2도는 본 고안에 따른 전사용지 안내구의 정면도인바, 제2도를 참조하여 본 고안에 대해 좀더 상세히 설명한다.Figure 2 is a front view of the transfer paper guide according to the present invention, with reference to Figure 2 will be described in more detail with respect to the present invention.
로울러(2)를 받쳐주는 지지부재(3)를 관통하면서 축(7)이 설치되어 있으며, 이 축(7)에는 용수철(6)이 설치되어지면서 이 용수철(6)이 지지부재(3)의 일측면과 연결되어져 있어서, 상기 지지부재(3)의 앞부분(제2도에서의 좌측부분)이 상측으로 들어 올려지도록 된다. 상기 축(7)의 양끝부분과 용수철(6)의 일측 끝부분은 각각 브라켓(8), (4)에 고정되게 된다.A shaft (7) is provided through the support member (3) supporting the roller (2), and the spring (6) is installed on the shaft (7) while the spring (6) is connected to the support member (3). It is connected to one side, so that the front part (the left part in FIG. 2) of the supporting member 3 is lifted upward. Both ends of the shaft 7 and one end of the spring 6 are fixed to the brackets 8 and 4, respectively.
이와 같이 구성된 본 고안의 작용에 대해 제3도를 참조하여 좀더 상세히 설명한다.The operation of the present invention configured as described above will be described in more detail with reference to FIG. 3.
복사기의 입구(10)를 통해서 용지(5)가 복사기내로 진입되게 되면, 이송로울러(11)에 의해 상기 용지(5)가 상기 전사용지 안내구에 설치된 로울러(2)의 상측으로 이동되게 되며, 이와 같이 감광드럼(1)의 하측과 로울러(2)의 상측으로 이동된 용지(5)는 그 두께가 두꺼울 경우 상기 로울러(2)하측에 위치된 지지부재(3)가 그 하측으로 이동됨으로써 상기 감광드럼(1)과 로울러(2)사이에서 적당한 압력을 받으면서 복사기의 출구(12)측으로 이송되게 된다.When the paper 5 enters into the copier through the inlet 10 of the copier, the paper 5 is moved to the upper side of the roller 2 provided in the transfer paper guide by the transfer roller 11, Thus, when the paper 5 moved to the lower side of the photosensitive drum 1 and the upper side of the roller 2 is thick, the support member 3 positioned below the roller 2 is moved to the lower side thereof. Under the appropriate pressure between the photosensitive drum 1 and the roller 2, it is transferred to the outlet 12 side of the copier.
한편, 상기 용지(5)의 두께가 정상용지의 두께보다 얇을 경우에는 상기 지지부재(3)가 용수철의 탄성력에 의해 그 용지(5)의 두께만큼 적당량 하측으로 이동됨으로써 상기 감광드럼(1)과 로울러(2)사이가 적당한 압력을 유지하게 되며, 따라서 용지에 나타나는 화상이 흩어짐없이 명확히 형성되게 된다.On the other hand, when the thickness of the paper 5 is thinner than the thickness of the normal paper, the support member 3 is moved downward by an appropriate amount by the thickness of the paper 5 by the spring elastic force so that the photosensitive drum 1 and The appropriate pressure is maintained between the rollers 2, so that the image appearing on the paper becomes clearly formed without scattering.
이와 같이 본 고안은 용수철의 탄성력을 이용하여 전사되는 복사용지에 균일한 힘을 작용시킴으로써 용지의 걸림이 방지되고, 감광드럼이 양호한 상태로 유지되며, 감광드럼의 구동계에 적당량의 부하가 걸려지게 되고, 용지에 형성되는 화상의 흩어짐이 방지되게 하는 효과가 있다.As such, the present invention applies a uniform force to the copying paper transferred by using the elastic force of the spring, thereby preventing paper jams, maintaining the photosensitive drum in a good state, and applying an appropriate amount of load to the driving system of the photosensitive drum. This is effective in preventing the scattering of the image formed on the paper.
