본 고안은 복사기 및 인쇄기등의 카세트에 적재된 용지를 공급하기 위한 장치에 관한 것으로서, 용기를 1매씩 정확하게 급지되도록 적층된 용지의 양측면을 경사면을 구비한 분리롤러로 눌러주면서 급지되도록 형성된 급지장치에 관한 것이다.The present invention relates to a device for supplying paper loaded in a cassette such as a copying machine and a printing machine. It is about.
종래에는 삽입부위의 전방양측코너 부분에 코너 분리조우(20)가 설치되어 용지의 가이드역할을 함과 동시, 용지를 눌러주면서 급지롤러(17')의 회전에 의하여 용지를 공급하였는데 이 방법은 여러장이 함께 공급되는 문제점을 안고 있어, 상기 문제를 해결하기 위하여 도면 제3도와 같이 적층된 용지의 옆면을 평행하게 눌러 만곡부가 형성되면 그 만곡부를 급지롤러(17')에 의해 급지하였는데, 적층된 용지가 많고 적음에 따라 누르는 힘의 조절이 어려워 여러장이 만곡되어 종전과 같이 여러장이 함께 공급되는 문제를 여전히 안고 있었다.Conventionally, the corner separating jaw 20 is installed at both front corners of the insertion part to serve as a guide of the paper, and at the same time, the paper is supplied by rotating the paper feed roller 17 'while pressing the paper. In order to solve the above problem, in order to solve the above problem, when the curved portion is formed by pressing the side surfaces of the stacked sheets in parallel as shown in FIG. 3, the curved portions were fed by the feed roller 17 '. There is a problem that the multiple sheets are bent together and the multiple sheets are still supplied with problems as it is difficult to control the pressing force.
따라서, 본 고안은 상기와 같은 문제점을 해결하기 위하여 안출 제공된 것으로, 적층된 용지의 모서리부(18)를 테이퍼 경사면(13)을 구비한 분리롤러(12)로 양측에서 누르게되면 최상부의 용지 1매만 만곡되게 되어, 이를 급지롤러(17)로 급지하는 것으로 이를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Therefore, the present invention is provided to solve the above problems, when pressing the edge portion 18 of the laminated paper from both sides with the separation roller 12 having a tapered inclined surface 13, only one sheet of top paper It is bent, it is fed to the paper feed roller 17 to be described in detail by the accompanying drawings as follows.
도면 제2도에서 보는 바와 같이, 종이 이송용 급지롤러(17)를 구비한 구동축(10)의 스톱퍼(16)와 단턱(11)사이에 스프링체(12)로서 측방 탄설된 상태로 결합 설치될 종이 분리용 롤러를 형성함에 있어서, 롤러(14)의 내측 전주면에는 하방에 적층된 종이 모서리부(18)와 접촉될 테이퍼경사면(13)을 구비한 것이다.As shown in FIG. 2, a spring body 12 is coupled to the stopper 16 and the step 11 of the drive shaft 10 having the paper feed roller 17 to be coupled and installed sideways. In forming the paper separating roller, the inner circumferential surface of the roller 14 is provided with a tapered inclined surface 13 to be in contact with the paper edge portion 18 stacked below.
이상과 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
카세트내에 적층된 용지(30)의 최상면을 수평방향으로 급지롤러(17)에 의해 압력이 가해지면, 스프링 지지용 단턱(11)에 탄동 설치된 압축스프링(12)에 의해 테이퍼 경사면(13)을 구비한 분리롤러(14)가 용지의 모서리부(18)를 압압하게 되면 분리롤러(14)와 급지롤러(17) 사이의 최상층의 위치한 용지(30)가 만곡부(19)를 형성하게 되면 구동축(10)의 회전과 함께 급지롤러(17) 및 분리롤러(14)가 동일방향으로 용지를 공급하게 되면 삽입부 전방에 위치한 코너분리조우(20)가 용지를 정확하게 삽입되도로 눌러주며 가이드 역할을 하게 되는 것으로, 계속적으로 용지가 공급되어 적층된 용지의 부피가 줄어들 경우에는 테이퍼경사면(13)을 구비한 분리롤러(14)가 페더키(15) 및 압축스프링체(12)의 작용에 의해 축방향으로 이송하며 용지의 모서리부(18)를 눌러 마지막 1장까지 만곡부를 형성하게 하여 용지를 공급하므로 본 고안의 목적을 달성하는 것으로 정확하게 용지를 1매씩 공급하게 되므로 용지를 절약할수 있고 또한, 기기의 오조작을 방지할 수 있어 능률적으로 업무에 임할수 있는 매우 유용한 고안이다.When pressure is applied to the uppermost surface of the paper 30 stacked in the cassette by the feed roller 17 in the horizontal direction, the tapered inclined surface 13 is provided by the compression spring 12 mounted on the spring support step 11. When the separation roller 14 presses the edges 18 of the paper, the driving shaft 10 is formed when the sheet 30 positioned on the uppermost layer between the separation roller 14 and the paper feed roller 17 forms the curved portion 19. When the feed roller 17 and the separation roller 14 feed the paper in the same direction with the rotation of), the corner separation jaw 20 located in front of the insertion part presses the paper accurately so as to guide the paper and serves as a guide. When the volume of the laminated paper is reduced by continuously feeding the paper, the separating roller 14 having the tapered inclined surface 13 is moved in the axial direction by the action of the feather key 15 and the compression spring body 12. Press the edge (18) of the paper to Since the paper is fed by forming the curved portion, the paper is fed one by one precisely to achieve the object of the present invention, which saves paper and prevents misoperation of the machine. It is a useful design.
