小さくなる。(According to claim 1) If the cutting paper is placed on the upper surface of the base and the slide body is manually slid in one direction, the disc blade moves in the cutting direction while being in contact with the lower blade. The cutting paper can be cut along the line along which the disc blade runs. Further, since the disc blade is rotatable, the frictional resistance of cutting can be reduced. Since the horizontal guide rod is below the upper surface of the base, the height dimension including the base, the horizontal guide rod, and the paper holder is reduced.

進むことができる。When the slide body is manually slid in one direction (according to claim 2), the pinion portion that meshes with the rack portion of the paper retainer rotates, and the rotation causes the second shaft member and the interlocking connecting means. It is transmitted to the disc blade via the first shaft member. Therefore, at the same time when the slide body slides, the disc blade reliably rotates with torque, and the cutting paper can be smoothly cut.

However, since it rolls on the cutting paper, it is possible to prevent the cutting paper from being displaced. In addition, when the total thickness of the cutting paper becomes large, the pressing roller is lifted, the slide body becomes inclined accordingly, and a force for pressing the disc blade to the lower blade acts on the disc blade. To do. For this reason, the disc blade does not escape from the lower blade during cutting, and accurate cutting is possible even when the total thickness of the cutting paper is large.

Since the paper is cut, the cut paper can be accurately divided into two along the dividing center line. Further, the cross section L of the cutting paper positioning mechanism is
If both edges of the cutting paper are brought into contact with the vertical portion of the letter-shaped paper receiving piece, the cutting paper will not be displaced. Since the swing arms of the dogleg frame have the same opening angle, the paper receiving piece is held in a fixed direction. Further, since one swing arm and the other swing arm of the pair of doglegged frame portions in the cutting direction are connected to each other by the horizontal connecting rods, respectively, The opening angles of the four rocking arms are the same and 2
The projecting dimensions of the individual paper receiving pieces from the base are also the same. Further, the link frame body having a hexagonal shape in plan view can be slid in the cutting direction with respect to the base, and the cutting paper can be moved to any position in the cutting direction.

好な切れ味が得られる。Simultaneously with or immediately after the fixing of the cutting paper P, the disc blade 5 reaches the cutting paper P and the cutting is started. At this time, since the pinion portion 14 of the disc blade forced rotation mechanism 68 meshes with the rack portion 15 and the pinion portion 14 rotates, the rotation of the pinion portion 14 causes the second shaft member 64, the interlocking connecting means 66, and the first connecting member 66.
It is transmitted to the disc blade 5 via the shaft member 63, and the disc blade 5 rotates with torque (see FIGS. 5 and 6). As a result, the frictional resistance at the time of cutting the cut paper P is reduced, and good cutting performance is obtained.

That is, if the number of teeth of the first gear 70a, the second gear 70b, and the third gear 70c of the interlocking coupling means 66 of the disc blade forced rotation mechanism 68 is adjusted, the rotation speed of the pinion portion 14 (second shaft member 64). Since it is possible to change the rotation speed ratio of the disk blade 5 (first shaft member 63), it is possible to easily set R <S.

The cutting paper P is firmly fixed, and the shearing resistance that acts during cutting can be reduced (see FIGS. 3 and 11). Therefore, it can be cut smoothly.

Moreover, since the pressing roller 10 is lifted, the mounting member 8 of the slide body 4 is moved by the guide roller 23 as shown by the arrow B.
Can be lifted around the upper end of the. As a result, the disc blade 5 is pressed against the lower blade 16, so that the disc blade 5 does not separate from the lower blade 16 during cutting, and even if the total thickness of the cutting paper P is large, it is cut to an accurate size. it can.
