Claims (1)

[Scope of Claim for Utility Model Registration] (1) A pair of upper and lower tool post guides in which guide grooves are provided on both the top and bottom surfaces of the tool post on which the round blade is rotatably supported, and the guide grooves are provided in a straight line. The tool rest is fitted to the rail and runs along the tool post guide rail, and the cutting edge of the round knife is pressed against a fixed blade provided parallel to the tool post guide rail, and the round blade and the round blade are pressed against each other. In a paper cutter that cuts paper or the like placed between a fixed blade and a fixed blade, the pair of upper and lower tool post guide rails are provided so as to face each other in a plane perpendicular to the axial center line of the guide groove of the tool post. At the same time, the guide grooves on the upper and lower surfaces of the tool rest are formed into a bowtie shape with a minimum width in a plane perpendicular to the spindle axis of the round blade and gradually widening toward both sides in the traveling direction. , characterized in that drive wires for running the tool post are anchored to both sides of the tool post in the running direction at a position away from a plane perpendicular to the center line in the width direction of the guide groove toward the round blade. Paper cutter. (2) Claim 1 characterized in that the rear surface of the turret is wedge-shaped with a thick central part of the turret and inclined on both sides in the running direction, and shifters opposite to the wedge-shape are provided on both ends of the cutter frame. Paper cutter as described in section. (3) Guide grooves are provided on both the front and rear surfaces of the tool post on which the round blade is rotatably supported, and the guide grooves are fitted into the front and rear pair of tool post guide rails provided in a straight line. The table is moved along the turret guide rail, and is placed between the round blade and the fixed blade while pressing the cutting edge of the round blade against a fixed blade provided parallel to the turret guide rail. In a paper cutter for cutting paper, etc., the pair of front and rear tool post guide rails are provided so as to face each other horizontally, and the depth of the guide grooves on the front and rear surfaces of the tool post is adjusted to support the round blade. The minimum depth is in a plane perpendicular to the shaft axis, and the depth is gradually deepened toward both sides of the running direction, and the drive wire for running the tool post is parallel to the running direction, including the center of gravity of the tool post. The paper cutter is fixed to both sides of the tool rest in the traveling direction at a position away from the vertical plane toward the round blade. (4) Claim 3 characterized in that the rear surface of the cutter frame is wedge-shaped with a thick central part of the turret and inclined on both sides in the running direction, and shifters opposite to the wedge shape are provided on both ends of the cutter frame. Paper cutter as described in section.
