Claims

[Scope of Claim for Utility Model Registration] (1) A driving means drives a paper feed roller and a paper ejection roller provided before and after the paper running direction used in a computer printer, etc., so that the circumferential speed of the paper ejection roller is controlled by the paper feed roller. from a conveying plate that is driven at a circumferential speed greater than the circumferential speed of the paper, applies tension to the paper when the paper is caught by the paper ejection roller, and conveys the paper between the paper feed roller and the paper ejection roller. A paper cutting device that lifts the paper and cuts the paper by bringing it into contact with horizontal perforations for cutting provided at regular intervals perpendicular to the running direction of the paper with a roller provided while the paper is running, At the horizontal perforation, there is a disc-shaped roller whose position from the paper ejection roller is adjustable and positioned below the level of the lifted paper so as to match S, and a disc-shaped roller on both sides of the roller. A perforation cutting fin consisting of a pair of fin parts having a hypotenuse part protruding from the fin part, and a part of the transverse perforation being cut off by the roller, and a part of the fin cut out by the hypotenuse part of the fin part. A paper cutting device characterized in that the paper cutting device cuts the paper by bringing the vicinity of both sides of the horizontal perforation into contact with each other. (2) The above roller has a diameter of φ30mm or less and a diameter of 15m.
2. The paper cutting device according to claim 1, wherein the paper cutting device has a width of 4 mm or less and has a protrusion amount of 4 mm or less from the perforation cutting fin of the portion facing the paper transport plate. :(3) Utility model registration claim 1, characterized in that the roller has a radius on its outer peripheral surface.
The paper cutting device according to item 1 or 2. (4) The above-mentioned perforation cutting fin is made of metal, and the left and right dimensions of the above-mentioned roller are respectively 125rITM, and the above-mentioned paper is M in the direction in which the paper is conveyed, and is inclined toward the paper ejection roller side. A paper cutting device according to any one of claims 1 to 3 of the utility model registration claim. :
