본 발명은 롤(roll) 형태의 기록지를 사용하는 팩시밀리나 프린터 등의 사무기기에서 기록지 절단용 자동절단기에 관한 것으로서, 특히 절단속도가 향상되고, 소음이 저감되도록 하는 사무기기의 자동절단기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic cutting machine for cutting recording paper in office equipment such as a fax machine or a printer using a roll-type recording paper, and more particularly, to an automatic cutting machine of an office equipment for improving cutting speed and reducing noise. .

종래 사무기기의 자동절단기는 제1도와 제2도에 도시되는 바와 같이, 상단에 날이 형성된 고정칼(1)과, 고정칼(1)의 일단부에 회전 가능하도록 힌지(2)에 의해 연결되고 하단에 날이 형성되며 타단부에 롤러(3)가 회전 가능하게 지지되고 인장스프링(4)에 의해 탄지되는 구동칼(5)과, 구동칼(5)의 롤러(3) 외주면에 구름접촉되고 편심되게 축이 연결되는 구동캠(6)으로 구성되어 있다.As shown in FIG. 1 and FIG. 2, the automatic cutting machine of the conventional office equipment is connected by a fixed knife 1 having a blade formed at an upper end thereof and a hinge 2 rotatably at one end of the fixed knife 1. And a blade is formed at the lower end, and the roller 3 is rotatably supported at the other end and supported by the tension spring 4, and the rolling knife is contacted with the outer peripheral surface of the roller 3 of the driving knife 5. And eccentrically connected to the drive cam (6).

이와 같이 구성되는 종래 자동절단기는 롤(roll) 형태의 기록지로 사용하는 팩시밀리나 프린터 등에서 기록이 완료된 후 기록지를 자동으로 절단하기 위해 사용되며, 그 작동은 다음과 같다.The conventional automatic cutting machine configured as described above is used to automatically cut the recording paper after the recording is completed in a facsimile or printer, which is used as a roll-type recording paper, and the operation thereof is as follows.

기록이 완료된 기록지(P)가 이송되어 절단기에 다다르면, 편심된 구동캠(6)이 롤러(3)를 회전시켜 구동캠(6)의 편심량 만큼 구동칼(5)의 타단부를 누르게 된다. 이로 인해 구동칼(5)의 일단부가 힌지(2)를 중심으로 회전하게 되며, 인장스프링(4)이 탄발력을 축적하며 인장된다. 이 때, 고정칼(1)의 날과 구동칼(5)의 날이 비스듬하게 접촉되고, 날의 접촉점이 날의 일단부에서 타단부로 이동하게 되어, 고정칼(1)과 구동칼(5) 사이로 이송된 기록지(P)가 절단되게 된다. 한편, 절단이 완료되면, 인장스프링(4)의 탄발력에 의해 구동칼(5)이 상부로 이동되어 원위치로 복귀되게 된다.When the recording paper P on which the recording is completed is transferred to the cutter, the eccentric drive cam 6 rotates the roller 3 to press the other end of the drive knife 5 by the eccentric amount of the drive cam 6. As a result, one end of the driving knife 5 rotates about the hinge 2, and the tension spring 4 is tensioned while accumulating elastic force. At this time, the blade of the fixed knife 1 and the blade of the drive knife 5 contact at an angle, and the contact point of the blade moves from one end of the blade to the other end, so that the fixed knife 1 and the drive knife 5 The recording paper P transferred between the sheets is cut. On the other hand, when the cutting is completed, the driving knife 5 is moved upward by the elastic force of the tension spring 4 to return to the original position.

이러한 종래 사무기기의 자동절단기는 구동칼(5)이 힌지(2)에 의해 고정칼(1)에 지지되어, 힌지(2)를 중심으로 회전됨에 따라 구동칼(5)의 날과 고정칼(1)의 날이 점진적으로 접촉되며 기록지(P)를 폭방향으로 가로질러 절단하므로, 기록지 길이 만큼의 절단시간이 길어지고, 이에 따른 소음 발생도 길어지는 문제점이 있었다.The automatic cutting machine of the conventional office equipment is supported by the fixed knife (1) by the drive knife 5, the hinge 2, the blade and the fixed knife of the drive knife (5) is rotated about the hinge (2) Since the blade of 1) is gradually contacted and cuts across the recording paper P in the width direction, the cutting time is increased by the length of the recording paper, and thus there is a problem in that noise is also generated.

본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위해, 양단에서 중앙으로 날의 접촉이 진행되도록 구동칼과 고정칼을 구성하여, 기록지의 절단 속도가 향상되고 절단시 발생되는 소음이 저감되도록 하는 사무기기의 자동절단기를 제공하는데 있다.An object of the present invention is to solve the conventional problems as described above, by configuring the drive knife and the fixed knife so that the contact of the blade proceeds from both ends to the center, so that the cutting speed of the recording paper is improved and the noise generated during cutting is reduced To provide an automatic cutting machine for office equipment.

이하 첨부된 도면에 따라 본 발명의 실시예를 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention according to the accompanying drawings in detail as follows.

본 발명은 제3도와 제4도에서 도시되는 바와 같이, 양단이 절곡되어 내측으로 안내부(11)가 형성되고 상단에 날이 형성되는 고정칼(10)과, 고정칼(10)의 양측 안내부(11)에 양단부가 상하로 슬라이딩 가능하게 삽입되고 상단 양측에 인장스프링(21)이 탄지되며 하단중심에서 양쪽으로 경사지게 날이 형성되는 구동칼(20)과, 구동칼(20) 상단 중앙에 외주면이 밀착되고 편심으로 형성되는 구동캠(30)으로 구성됨을 그 기술적 구성상의 특징으로 한다.As shown in FIG. 3 and FIG. 4, both ends of the fixed knife 10 and the fixed knife 10 having the guide part 11 formed therein and a blade formed at the upper end, as shown in FIGS. Both ends are slidably inserted into the upper and lower ends 11, the tension spring 21 is supported on both sides of the upper end and the driving knife 20 and the blade is formed to be inclined to both sides at the lower center, and the driving knife 20 in the upper center The outer circumferential surface is in close contact with the drive cam 30 is formed eccentrically characterized by the technical configuration.

이와 같이 구성되는 본 발명은 구동캠(30)의 회전에 의해 구동칼(20)이 고정칼(10)의 안내부(11)를 따라 하향으로 직선 이동되고, 인장스프링(21)의 탄발력에 의해 구동칼(20)이 상부로 복귀되며, 이 때 구동칼(20)과 고정칼(10)의 날 접촉이 양단에서 중앙으로 진행된다.According to the present invention configured as described above, the driving knife 20 is linearly moved downward along the guide portion 11 of the fixed knife 10 by the rotation of the driving cam 30, and the elastic force of the tension spring 21 is increased. By the drive knife 20 is returned to the upper portion at this time, the blade contact between the drive knife 20 and the fixed knife 10 is advanced from both ends to the center.

한편, 기록지(P)에 기록이 완료된 시점에 다다르면, 구동캠(30)이 회전하여 구동칼(20)이 하방으로 이동하기 시작하고, 기록지의 선단부가 구동칼(20)과 고정칼(10) 사이에 위치되면, 기록지(P) 폭의 좌우 양단에서 동시에 절단되기 시작하고, 구동칼(20)이 하사점에 도달하기 조금전에 구동칼(20)의 날 중앙에서 절단이 완료되며, 절단이 완료된 후 계속 회전되는 구동캠(30) 편심부의 접촉에 의해 구동칼(20)이 약간 하방으로 더 이동한 후, 인장스프링(21)의 인장력에 의해 상부로 복귀된다. 또한, 구동칼(20)이 상사점에 다다르면, 구동캠(30)의 회전이 멈추게 되고, 다음 절단을 위해 대기하게 된다.On the other hand, when the recording paper (P) is reached when the recording is completed, the drive cam 30 is rotated and the drive knife 20 starts to move downwards, the front end portion of the recording paper drive knife 20 and the fixed knife 10 If it is positioned between, the cutting paper starts to be cut simultaneously at the left and right ends of the width of the paper P, and the cutting is completed at the center of the blade of the driving knife 20 just before the driving knife 20 reaches the bottom dead center, and the cutting is completed. After the drive knife 20 is further moved slightly downward by the contact of the eccentric portion of the drive cam 30 which is continuously rotated, it is returned to the upper portion by the tension force of the tension spring 21. In addition, when the driving knife 20 reaches the top dead center, the rotation of the driving cam 30 is stopped, and waits for the next cutting.

이러한 본 발명은 기록지(P)의 양쪽 끝에서 동시에 중앙으로 절단이 진행되므로, 일측에서 타측으로 절단이 진행되던 종래 자동절단기에 비해 절단 속도가 배로 빠르게 되며, 이로 인해 절단되는 시간만큼 절단소음도 줄어들게 된다.In the present invention, since the cutting proceeds to the center at both ends of the recording paper (P) at the same time, the cutting speed is doubled as compared to the conventional automatic cutting machine which is being cut from one side to the other side, thereby reducing the cutting noise as much as the cutting time. .

이상에서 살펴본 바와 같이, 본 발명은 양단에서 중앙으로 날의 접촉이 진행되도록 하여, 기록지의 절단이 빠르고 절단시 발생되는 소음도 줄여 주도록 하는 매우 유용한 것이다.As described above, the present invention is very useful to allow the cutting of the recording paper to be faster and to reduce the noise generated during the cutting so that the contact of the blade proceeds from both ends to the center.
