(Prior art) - As shown in FIG. 9, a conventionally used shredder is provided with a large number of cutter blades 2 having edges 1 formed thereon at equal intervals in the axial direction, and each cutter blade 2 is connected to the other cutter blade. Insert it between 2 and rub the edges together, and
As shown in Figure O, the cutter blade 2 is rotated in the direction of the arrow, and the paper 3 is cut at the point A by the shearing force of the edge 2. However, in this shredder, the paper is cut with the shearing force of the edge, so a considerably large shearing force is required at the time of cutting. For that purpose, cutter blade 2
The power required to rotate the shredder increases, the power source becomes large, the shredder becomes large, and it takes up a large installation space to be used as a household shredder, making it inappropriate to use this shredder for household use. It is. Therefore, a miniaturized shredder that can be used for household use and meets social needs has already been developed (Japanese Patent Application No. 1-28284).

(Problem to be Solved by the Invention) In the above-mentioned shredder, the paper is cut in the center of the paper passed through the concave groove 5 with the cutting edge of the circular blade 9, so the cut paper strip is rotating. The rotational force of the cutter blade 10 often causes the circular blades 9 to be caught in the gap between the circular blades 9 or into the concave groove 5 of the rotating feed roller 8. When the paper strips cut in this way are rolled up, there is a problem in that the paper strips are wound around the feed roller 8 and the cutter blade 10, making them difficult to rotate. Another problem is that when a strip of paper is wrapped in this way, it is difficult to remove it, reducing the value of the product.

(Function) Since the present invention is configured as described above, the paper fed between the feed roller and the cutter blade is passed through the concave groove of the feed roller and is then passed through the slit of the cutter blade entrainment prevention plate. It is cut one by one using a cutter blade with a protruding cutting edge. This cutting is not done by shearing force but by the cutting edge of the circular blade, so the force required for this cutting is small. The paper cut into strips is then cut into strips by the cutter blades, which protrude from the slits one by one to close the space between the cutter blades. It is guided by an entrainment prevention plate and is discharged downward without being entrained.

First, in FIG. 4, the circular blades 9 of the cutter blade 1O are arranged at equal intervals in the axial direction, and are connected to the feed roller 8 and the cutter blade so that the cutting edge of the circular blade 9 is inserted into the groove 5 of the feed roller 8. IO is arranged. Therefore, as shown in FIG. 2, the cutter blade entrainment prevention plate 11 is made by forming slits 28 made of thin steel into an arc shape as shown in FIG. This slit plate 28 is fixed to a holder 30 bent into a groove shape with a fixing member 3I. The cutter blade entrainment prevention plate 11 is assembled so that a part of the circular blade 9 comes out from the slit 29 of the slit plate 28. In FIG. 4, both ends of the shafts 33, 34 of the feed roller 8 and the cutter blade 1O are supported by bearings 32 provided in the casing, and gears 35, 36 are provided at the other ends, respectively. Further, a gear 38 is provided on the shaft 37 of the motor 13.
The driving force of No. 3 is transmitted to the feed roller 8 and the cutter blade IO via gears 38, 36, and 37. As shown in FIG. 5, a handle shaft 40 is provided on the side surface of the casing 17, and the handle 39 is attached to the handle shaft 40 so as to fit into the elongated hole 4I.

Next, the operation of this embodiment configured as described above will be explained. First, in use, by turning on the power switch 42, the optical switch 44 is turned on, but the motor 13 does not rotate.Then, when paper is inserted into the slit 16, the optical switch 44 is activated, and the motor 13 is rotated and fed. The roller 8 and cutter blade lO rotate. By doing this, even if the power switch 42 is turned on, the motor 1 will not operate unless paper is inserted through the slit 16.
3 does not rotate, so the battery 14 saves power. Furthermore, since the number of sheets of paper inserted is limited by the width of the slit 16, the motor 13 is not overloaded, protecting the motor 13, and eliminating power consumption of the battery 14 due to overload, thereby extending the life of the battery 14. becomes possible. Then, a part of the circular blade 9 of the cutter blade summer 0 comes out one by one from the slit 29 of the slit plate 28 of the cutter blade entrainment prevention ill, so the paper that has been removed by +4 from the slit 16 is While the hook is being passed over the HI 45, its center portion is cut off by the cutter blade 10. When the paper is cut by the cutter blade lO in this way, a frictional force is generated between the circular blade 9 and the paper due to the cut made by the circular blade 9, and this frictional force acts as a force to pull the paper in and the paper is cut into strips. be done. The paper cut into strips in this way is guided downward by the cutter blade entrainment prevention plate 11 which protrudes one circular blade 9 from the slit 29 of the slit plate 28 and closes the space between the circular blades 9. At the same time, it is also guided by the feed roller entrainment prevention plate 12, which is provided so that its tip is substantially in contact with the outer periphery of the feed roller 8, and is pushed downward. This prevents the cut paper strips from getting caught on the right side of the feed roller 8 and the cutter blade IO side, and the feed roller entrainment prevention plate 12 is provided to cover the bottom of the feed roller 8 and the cutter blade IO side. The entrainment prevention plate 11 has the circular blades 9 protruding one by one from the slit 29 to close the space between the circular blades 9, so that the cutter blade 10 is wrapped in the cutter blade entrainment prevention plate grain. It has become.

Even if the trash box 19 is filled with compressed paper that has been pushed downward, the paper that has been cut into strips will not get caught up in the feed roller 8 and the cutter blade 10. This also makes it possible to minimize the internal volume of the trash can 19. By pressing the lock release member 26, the bottom plate 23 is unlocked and the compressed paper is discharged.

(Effects of the Invention) As detailed above, according to the present invention, the cutter blade entrainment prevention plate has a slit plate in which the circular blades of the cutter blade protrude one by one to close the space between the circular blades. This makes it possible to cut the paper with the cutting edge of the circular blade protruding from the slit plate, making it possible to cut the paper with a small amount of force. Entanglement can be prevented. In this way, the cutter blade entrainment prevention plate has the two functions of reducing the power required for cutting and preventing the cut paper strips from being entrained.In addition, the cutter blade entrainment prevention plate has an entrainment prevention IF for the feed roller at the bottom of the feed roller. Since the shredder is provided with a handle, the motor and its drive source can be made smaller to make the shredder body smaller, and furthermore, even if discharged paper is compressed and stuffed into the trash can, it will not get caught, so the trash can can be made smaller. In addition, since there is no shredded paper caught in the motor, there is no overload on the motor, which protects the motor, extends the life of the battery, and eliminates the work of removing paper caused by paper caught in the motor, which greatly improves product value. I can do it.
