In the above-mentioned structure, even it is overlapping gradually to handle the concavo-convex edge of a knife 14 of tooth 7 and cutting knife 12, the angle of the concavo-convex edge of a knife 14 and processing tooth 7 changes also few, can guarantee stable cut-out.In addition, because the edge of a knife of the concavo-convex edge of a knife 14 is to eat the into shape of processing tooth 7, so, with processing tooth 7 the straw class is pushed, can cut off well.
In addition, direction from the plate body that is orthogonal to cutting knife 12, a plurality of protuberance 14a and recess 14b have been formed on the cutting knife 12 repeatedly alternately and when becoming the edge of a knife of linearity, overlapping along with process cartridge 8 and cutting knife 12, the corner cut of the edge of a knife increases slightly, one downcuts the straw class point-blank, so, can reduce load change.
In addition, also can be as Figure 47 and the relative configurations that constitutes cutting knife 12 and handle tooth 7 shown in Figure 48.Promptly, form the edge of a knife of cutting knife 12 in this wise: see from the side, a plurality of protuberance 14a of the concavo-convex edge of a knife 14 and recess 14b repeatedly alternately and become inwards recessed circular-arcly or will handle the rotation left-hand seat side part of tooth 7 form circular-arc (Figure 47) that bloats towards the outside or form linearity (Figure 48).
Like this, in the structure of Figure 47, when the concavo-convex edge of a knife 14 and the rotation left-hand seat side part of handling tooth 7 of cutting knife 12 were overlapping, the contact length lengthening can cut off the straw class at one stroke.In addition, as shown in figure 48, see from the side that when the edge of a knife of the concavo-convex edge of a knife 14 was formed linearity, the concavo-convex edge of a knife 14 was short with the lap of handling tooth 7, can cut off the straw class with lightening the load.
In addition, also can and shown in Figure 50 constitute cutting knife 12 and handle tooth 7 as Figure 49.Promptly, form the edge of a knife of cutting knife 12 in this wise: see from the side, a plurality of protuberance 14a of the concavo-convex edge of a knife 14 and recess 14b replace and become inwards recessed circular-arc (Figure 49) or linearity (Figure 50) repeatedly, the rotation left-hand seat side part of handling tooth 7, slightly erect squarely from the outer peripheral face of process cartridge 8.
Like this, in structure shown in Figure 49, handle tooth 7 and be with the rotation of straw class,, can improve the cut-out performance though horsepower increases.In addition, when the edge of a knife shown in Figure 50, that see the concavo-convex edge of a knife 14 from the side was linearity, the concavo-convex edge of a knife 14 was short with the lap of handling tooth 7, can cut off the straw class with lightening the load.
