2, 2' : 전후 내면부 4 : 브러쉬2, 2 ': front and rear inner portion 4: brush

5 : 분리 고무판5: separation rubber plate

본 고안은 전자복사기나 레이저 프린터등에 사용되는 복사지의 카세트에 있어서, 복사지가 겹쳐서 공급되는 것을 방지할 수 있도록 한 전자복사기의 복사지 중송 방지장치에 대한 것이다.The present invention relates to a copy paper transfer prevention device of an electronic copy machine in which a copy paper cassette used in an electronic copy machine or a laser printer can be prevented from being fed over.

종래의 카세트는 복사지의 적층 단면형상이 직사각형상으로 되고, 또 급지로울러의 마찰력만을 이용하여 한 장씩 이송토록 하였기 때문에 카세트에 복사지를 담을 때 분리시키지 않은 상태로 담게 되면 서로 붙어있게 되어 여러장이 함께 이송되는 중송현상이 자주 발생하는 폐단이 많았으며, 또 분리시켜서 담아도 복사지 자체의 중량과 급지로울로의 누름력등에 의해 복사지 간의 정전기력이 발생되어 중송되는 예가 허다하였고, 이런 현상은 날씨가 습할 때에는 더욱 심하게 발생되어 사용상 많은 문제점들이 있었다.Conventional cassettes have a rectangular cross-sectional shape of copy paper, and are transported one by one using only the friction force of the paper feed roller. There were many wastes that frequently occurred during heavy transport, and even when separated, the electrostatic force between the copy papers was generated by the weight of the copy paper itself and the pressing force of the feeding roller. There were many problems in use that occurred badly.

본 고안은 이러한 점들을 해결하기 위해 고안한 것으로 카세트의 전후 내면부를 경사면으로 형성하므로 복사지의 적층 단면이 나란히 꼴로 되게 하여 복사지를 담으면 자동적으로 서로 분리되도록 하였고, 또 앞쪽 내면에는 분리용 브러쉬와 그 상부에 분리고무판을 각기 착설하여 더욱 효과적으로 중송이 방지되게한 것이다.The present invention was devised to solve these problems, so that the front and rear inner surfaces of the cassette were formed as inclined surfaces so that the laminated sections of the copy paper were side-by-side in shape so that the copy paper was automatically separated from each other. Separate rubber plate is installed on the upper part to prevent the feeding more effectively.

이하, 본 고안의 구성 및 작용상태를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation state of the present invention will be described in detail by the accompanying drawings.

카세트(1)의 전후 내면부(2) (2')를 각기 경사면으로 형성하여 복사지(3)를 담으면 그 적층단면이 나란히꼴로 되게 하므로 복사지(3)는 담긴 상태에서 일차적으로 서로 분리되게하며, 또 앞쪽 내면부(2)에는 브러쉬(4)를, 그 상면에는 분리 고무판(5)를 각각 착설하여 카세트(1)를 복사기에 장착하면 상승되는 받침판(6)에 의해 복사지(3)의 앞쪽 부분이 들려지면서 상기 브러쉬(4)에 의해 재차 분리되고, 또 분리고무판(5)에 의해 중송이 방지되도록 한 것이다.The front and back inner surfaces 2, 2 'of the cassette 1 are each formed with an inclined surface to contain the copy paper 3 so that the laminated sections are parallel to each other, so that the copy paper 3 is primarily separated from each other in the contained state. In addition, the front inner surface portion (2) of the brush (4), the upper surface of the separation rubber plate (5) respectively installed on the cassette 1 to the copier, the support plate (6) which is raised to raise the copy paper 3 The front part is lifted and separated by the brush 4 again, and the heavy rubber is prevented by the separating rubber plate 5.

미설명 부호"17"은 급지로울러이다.Reference numeral 17 denotes a paper feed roller.

이와 같이 구성되는 본 고안은 카세트(1)에 복사지(3)를 담으면 경사면으로된 전후 내면부(2)(2')에 의해 적층단면이 나란히꼴 상태로 되어 일차적으로 각기 분리되며, 또 복사기에 장착시키면 제2도 가상선(A)과 같이 받침판(6)에 의해 앞쪽 부분이 들려지는 과정에서 브러쉬(4)와 마찰이 되기 때문에 재차 분리되어 중송이 방지되는데, 만일 이러한 과정을 거친 다음에도 분리가 되지 않은 경우에는 분리고무판(5)에 의해 최종적으로 분리되어 중송이 효과적으로 방지되는 것으로, 이 때 분리고무판(5)의 작용원리는 제3도에서 보는 바와같이 급지 로울러(17)가 겹쳐진 복사지들중 상부 복사지(3a)를 이송 시키려는 힘은 "F1-F2"이고, 하부복사지(3b)가 분리고무판(5)에 의해 이송이 저지되는 힘은 “F3-F2"이므로 “F1＞F2" 이고, "F3＞F2"이면 복사지들은 확실하게 분리되어 중송이 방지되는 것이다.When the copy paper 3 is contained in the cassette 1, the present invention configured as described above has a laminated cross section side by side by the front and rear inner surface portions 2 and 2 ', which are inclined surfaces, and are separated from each other primarily. If it is attached to the second part as the virtual line (A) in the process of lifting the front part by the support plate (6), because the friction with the brush (4) is separated again to prevent heavy feeding, even after this process If it is not separated, it is finally separated by the separating rubber plate 5 to effectively prevent heavy feeding. At this time, the principle of action of the separating rubber plate 5 is copy paper having the paper feed rollers 17 overlapped as shown in FIG. Among them, the force for conveying the upper copy paper 3a is "F1-F2", and the force for which conveyance of the lower copy paper 3b is prevented by the separating rubber plate 5 is "F3-F2", so it is "F1> F2". If "F3> F2", copy paper is separated Uh jungsong will be prevented.

이와 같은 작용에 의해 복사지를 분리되게 하는 본 고안은 카세트의 전후내면부만 경사지게 형성하거나, 또는 브러쉬나 분리고무판들 중 어느 하나만 설치사용 하여도 복사지를 효과적으로 분리시켜 줄 수 있게되지만, 이들을 결합하여 사용하므로 복사지의 분리가 더욱 확실하고도 효과적으로 이루어지게 되어 복사지의 손실등을 최대한 방지시켜주는 등 매우 유용한 고안이다.The present invention that separates the copy paper by this action can be formed to be inclined only to the front and rear inner surface of the cassette, or by using only one of the brush or the separation rubber plate to effectively separate the copy paper, but used in combination Therefore, the separation of copy paper becomes more reliable and effective, so it is a very useful design to prevent the loss of copy paper as much as possible.
