As shown in FIG. 1, the paper transfer wheel device is generally composed of a belt 3 and a cog wheel 4, and the lower part 2 of the copy machine. When the paper jams during the copying process, or when the copier is opened during normal maintenance work, it is divided into the upper part 1 and the lower part 2 and attached to the gear wheel 4 attached to the lower part 2. When removing jammed paper and maintenance work, there is a risk of injury.

이를 방지하기 위해 상부의 감광체 하우징(5)에 톱니 바퀴(4)를 가설한 것도 있으나, 그 구조가 복잡하여 비용이 많이 들며 공간도 많이 차지하는 단점이 있다.In order to prevent this, the cogwheel 4 is hypothesized in the upper photosensitive housing 5, but the structure is complicated, which is expensive and takes up a lot of space.

본 고안은 이러한 문제점에 따라 안출된 것으로, 그 목적은 복사기의 개방시 볼부재가 이동하여 트랜스퍼 휠 케이싱이 회전하여 리세스부에 수납되어 복사기 내부에 걸린 용지 제거시 또는 통상의 보수작업시 작업자가 안전하게 작업할 수 있고, 또한 구조가 간단한 전자사진 응용기기의 페이퍼 트랜스퍼 휠 장치를 제공하는 것이다.The present invention has been devised in accordance with this problem, and the object thereof is that the ball member moves when the copier is opened so that the transfer wheel casing is rotated and stored in the recess to remove the paper jammed in the copier or during maintenance. It is to provide a paper transfer wheel device for an electrophotographic application that can be safely operated and has a simple structure.

이러한 목적을 달성하기 위한 수단으로서, 본 고안의 페이퍼 트랜스퍼 휠 장치는 상면에는 수평면과 경사면이 형성되고, 하면에는 걸림면이 형성되고, 측면에는 힌지구멍이 형성된 리세스부를 전방하단부에 형성한 하우징과, 측면에는 상기 힌지구멍에 끼워지는 힌지축이 돌출 형성되고, 상면에는 개방부가 형성되고, 하면에는 수평면과 경사면이 형성되고 수평면 일단 하측에 트랜스퍼 지지레버가 형성되고, 상기 리세스부에서 회전 가능한 트랜스퍼 휠 케이싱과, 상기 트랜스퍼 지지레버에 아이들 회전하도록 착설된 트랜스퍼 휠과, 상기 트랜스퍼 휠 케이싱이 회전하여 상기 하우징의 리세스부내에 수납되도록, 상기 케이싱내부에서 좌우로 이동되는 볼부재로 이루어진 것을 특징으로 한다.As a means for achieving the above object, the paper transfer wheel device of the present invention has a housing having a horizontal surface and an inclined surface is formed on the upper surface, the engaging surface is formed on the lower surface, the recessed portion formed on the front lower end and the hinge hole is formed on the side surface; The side of the hinge shaft is inserted into the hinge hole is formed protruding, the upper surface is formed with an open portion, the lower surface is formed with a horizontal surface and an inclined surface, one end of the horizontal surface is formed with a transfer support lever, the transfer rotatable in the recess A wheel casing, a transfer wheel installed to idlely rotate the transfer support lever, and a ball member moved left and right within the casing so that the transfer wheel casing rotates and is received in a recess of the housing. do.

또한 본 고안의 페이퍼 트랜스퍼 휠 장치는 상기 트랜스퍼 휠 케이싱의 내부면에 소음방지부재를 설치하고, 상기 하우징의 하면에는 셔터부재를 더 포함하는 것을 특징으로 한다.In addition, the paper transfer wheel device of the present invention is characterized in that the noise prevention member is installed on the inner surface of the transfer wheel casing, the lower surface of the housing further comprises a shutter member.

이하 첨부된 도면을 참조하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 고안에 따른 페이퍼 트랜스퍼 휠 장치는 제2도 내지 제5도에 도시된 바와 같이 감광체 하우징(10)과, 트랜스퍼 휠 케이싱(20)과, 트랜스퍼 휠(30)과, 볼부재(40)로 구성된다. 감광체 하우징(10)에는 상면과 수평면(11)과 경사면(12)이 형성되고, 하면에는 걸림면(15)이 형성되고, 측면에는 힌지구멍(14)이 형성된 리세스부(13)를 전방하단부에 형성한다. 트랜스퍼 휠 케이싱(20) 측면에는 리세스부(13)의 힌지구멍(14)에 끼워지는 힌지축(24)이 돌출 형성되고, 상면에는 개방부(23)가 형성되고, 하면에는 수평면(25)과 경사면(26)이 형성되고 수평면 일단 하측에 트랜스퍼 지지레버(22)가 형성되어, 힌지축(24)을 중심으로 리세스부(13)에서 회전가능하다. 트랜스퍼 휠(30)은 트랜스퍼 휠 케이싱(20)의 하면에 형성된 트랜스퍼 지지레버(22)에 아이들 회전하도록 착설된다. 볼부재(40)는 트랜스퍼 휠 케이싱(20)이 회전하여 하우징의 리세스부(13)내에 수납되도록 케이싱(20) 내부에서 좌우로 이동된다.The paper transfer wheel device according to the present invention comprises a photosensitive member housing 10, a transfer wheel casing 20, a transfer wheel 30, and a ball member 40, as shown in FIGS. do. The photosensitive member housing 10 has an upper surface, a horizontal surface 11 and an inclined surface 12, a lower surface having a locking surface 15, and a recessed portion 13 having a hinge hole 14 formed at a lower side thereof. To form. A hinge shaft 24 fitted into the hinge hole 14 of the recess 13 is protrudingly formed on the side of the transfer wheel casing 20, an opening 23 is formed on the upper surface thereof, and a horizontal surface 25 on the lower surface thereof. And an inclined surface 26 are formed, and a transfer support lever 22 is formed below one end of the horizontal surface, and is rotatable in the recess 13 about the hinge shaft 24. The transfer wheel 30 is installed so as to idle-rotate the transfer support lever 22 formed in the lower surface of the transfer wheel casing 20. The ball member 40 is moved left and right inside the casing 20 so that the transfer wheel casing 20 is rotated to be accommodated in the recess 13 of the housing.

트랜스퍼 휠 케이싱(20)의 내부면에는 소음방지부재(50)를 설치하는 것이 바람직하다. 또한 하우징(10)의 하면에는 셔터부재(60)를 더 포함하는 것이 좋다.It is preferable to install the noise preventing member 50 on the inner surface of the transfer wheel casing 20. In addition, the lower surface of the housing 10 may further include a shutter member 60.

제3도에 도시된 바와 같이, 복사기를 닫았을 경우 트랜스퍼 휠 케이싱(20)내의 볼부재(40)는 왼쪽에 위치되며 트랜스퍼 휠(30)이 시계 반대방향으로 회전하여 전사기(6)를 거쳐 벨트(3)위로 이송된 용지에 적절한 압력을 주어 정착기(7)쪽으로 용지를 이송한다. 이때, 용지가 걸리거나 또는 통상의 보수작업을 위해 복사기를 개방하면 제4도에 도시된 바와 같이 복사기 개방각도(가)가 트랜스퍼 휠(30) 설치각도(나)(제2도)보다 크기 때문에 볼부재(40)는 오른쪽으로 굴러가서 트랜스퍼 휠 케이싱(20)은 힌지축(24)을 중심으로 시계방향으로 회전되므로서 하우징(10)의 리세스부(13)내에 수납된다.As shown in FIG. 3, when the copier is closed, the ball member 40 in the transfer wheel casing 20 is located on the left side, and the transfer wheel 30 is rotated counterclockwise to move through the transfer machine 6. Appropriate pressure is applied to the paper conveyed onto the belt (3) to convey the paper toward the fixing unit (7). At this time, if the paper jams or the copier is opened for normal maintenance, the copier opening angle (A) is larger than the transfer wheel 30 installation angle (B) (FIG. 2) as shown in FIG. 4. The ball member 40 is rolled to the right so that the transfer wheel casing 20 is rotated clockwise about the hinge axis 24 to be accommodated in the recess 13 of the housing 10.

한편, 다시 복사기를 닫게 되면 트랜스퍼 휠 케이싱(20)의 하면 경사각도(다)가 복사기 개방각도(가)보다 작기 때문에 볼부재(40)는 왼쪽으로 굴러가서 트랜스퍼 휠 케이싱(20)이 시계반대방향으로 회전하고 걸림면(15)에 의하여 정지되어 제3도와 같이 통상의 복사과정을 수행한다. 트랜스퍼 휠 케이싱(20) 정지작용을 걸림면(15)으로 하지 않고 하우징(10) 상면의 수평면(11)이 하도록 해도 좋다. 이와 같이 볼부재(40)의 좌우이동시 발생되는 소음을 방지하기 위해 트랜스퍼 휠 케이싱(20)의 내부면에 소음방지부재(50)를 설치하는 것이 좋다. 볼부재(40)는 원통형으로 대체해도 좋은 것은 물론이다.On the other hand, when the copier is closed again, since the inclination angle (C) of the lower surface of the transfer wheel casing 20 is smaller than the copier opening angle (C), the ball member 40 rolls to the left so that the transfer wheel casing 20 is counterclockwise. Rotation and stop by the locking surface 15 to perform a normal copying process as shown in FIG. The horizontal surface 11 of the upper surface of the housing 10 may be used instead of the stopping surface 15 of the transfer wheel casing 20. Thus, in order to prevent noise generated when the ball member 40 moves left and right, it is preferable to install the noise preventing member 50 on the inner surface of the transfer wheel casing 20. Of course, the ball member 40 may be replaced with a cylindrical shape.

통상의 보수작업중에 하우징(10)을 복사기에서 빼낼경우, 하우징(10)이 놓는 상태에 따라 트랜스퍼 휠(30)이 외부로 노출될 수도 있으므로, 이러한 위험을 방지하기 위해, 제2도 및 제3도에 도시된 바와 같이 하우징(10)의 하면에 셔터부재(60)를 설치하는 것이 바람직하다.When the housing 10 is removed from the copier during the normal maintenance work, the transfer wheel 30 may be exposed to the outside depending on the state in which the housing 10 is placed. As shown in the figure, it is preferable to install the shutter member 60 on the lower surface of the housing 10.

또한, 도시하지는 않았지만, 셔터부재(60)를 고정할 수 있는 고정부재를 하우징(10)의 전면하단에 설치하여 셔터부재(60)의 선단이 고정부재에 결합되어 고정될 수도 있고, 셔터부재(60)를 절첩형으로 형성할 수도 있음은 물론이다.In addition, although not shown, a fixing member capable of fixing the shutter member 60 may be installed at the lower end of the front surface of the housing 10 so that the tip of the shutter member 60 may be coupled to the fixing member to be fixed. Of course, it is also possible to form 60) folded.

이상과 같이 본 고안에 따르면, 복사기의 개방시의 트랜스퍼 휠의 노출을 간단한 구조로서 방지할 수 있는 것이다.According to the present invention as described above, the exposure of the transfer wheel at the time of opening the copier can be prevented as a simple structure.
