Therefore, when a large number of thick paper sheets are to be put on the shredder, they must be divided and supplied little by little, which is troublesome and time-consuming. It was

SUMMARY OF THE INVENTION The present invention has been devised so as to solve such a problem and to supply a large amount of thick paper sheets at a time so as to perform a cutting process. A supply unit capable of receiving a group of paper sheets at one time, a cutting unit internally provided with a cutter for cutting the paper sheets received from the supply unit into small pieces, and an accommodating unit capable of storing cut paper pieces in three layers in upper and lower layers In addition, the supply unit has a built-in cutter that cuts only the part where a large amount of paper sheets with thick end surfaces are attached, or the supply unit also divides a large amount of paper sheets into small pieces. The lid is configured to be openable and closable so that it can be supplied to the cutting portion or that at least the cutter can be operated when closed above the supply portion.

[0005]

Therefore, it is possible to feed all the large amount of thick paper sheets to the upper feeding portion at a time, and the feeding portion feeds the paper sheets to the lower cutting portion one after another while dividing the sheet into small portions. In the cutting section, a small amount of paper sheets can be effectively cut into small pieces by a cutter as in the conventional case, and can be received in a lower storage section. Further, a sheet group can be supplied to a supply section and a lid above it can be cut. When closed, at least the cutter is activated and the cutting operation can be started safely and automatically.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view of the shredder as a whole, in which the feeding section 1, the cutting section 3 and the accommodating section 4 are formed in three layers, that is, a compact structure. The leaf group A is widely opened so that the leaf group A can be supplied at one time, and at the opening, the front portion can be locked to the lock portion 9 and the ammunition machine 1
A lid 5 having a pressing plate 11 that is pressed by 0 and 10 is openably and closably provided, and a large amount of paper sheets A can be placed inside the supply unit 1 and the outer peripheral surface becomes a rough surface. A belt-shaped conveyor belt 12 is provided, and a belt-shaped conveyor belt 12 is provided downwardly along the peripheral edge portion of the conveyor belt 12 from a gap between a lower end of a guide plate 13 obliquely provided above the peripheral edge portion and an upper surface of the conveyor belt 12. In addition to providing a feeding path 14 for the feed, a guide plate 15 is installed on the outer periphery of the upper side of the feeding path 14 so as to be elastically pressurizable, and a large amount of paper sheet group A is divided into small amounts by the conveying belt 12 and sent to the feeding path 14. Configure to be able to feed. In addition, as a means for feeding a large amount of paper sheet into the lower portion while dividing it into small portions, it is possible to feed it by a small amount by a roller, or other appropriate means can be adopted.

In the second-layer cutting section 3 which is continuously provided below the feeding section 1, two cutters 2 and 2 similar to the conventional type which can cut a small amount of paper sheets into small pieces are provided below the feeding path 14. A beater 16 which is installed as desired, is installed in front of the cutters 2 and 2 for knocking down small cut pieces of paper downward, and inside the columns 7 below the cutting part 3, the cutting A hopper-shaped accommodating portion 4 capable of accommodating paper pieces falling from the portion 3 and capable of holding and pulling the handle 8 is provided as a third layer, and the upper portion of the supply portion 1 is
When the lid 5 is closed, a switch 18 for hitting the protrusion 17 of the lid 5 to start the cutters 2 and 2 and the conveyor belt 12 is provided, and a switch 6 for manual operation is also provided on the front side of the supply unit 1. To do.

Therefore, as shown in FIG. 1, the lid 5 is opened, and a large number of thick paper sheets A are placed as they are from the top as shown by the arrow A and placed on the carrier 12, and then the lid is closed. When 5 is rotated in the arrow B direction to close it, the pressing plate 11 is pressed against the sheet group A, the cutters 2 and 2 and the conveyor belt 12 are started, and the conveyor belt 1 is rotated in the arrow C direction.
2 is fed from the lower part of the paper sheet group A little by little to the feeding passage 14, and the small amount of paper fed out in the feeding passage 14 as indicated by the arrow D is as it is by the cutters 2 and 2. Similarly, the paper piece is cut into small pieces, is beaten down by the rotating beater 16 as shown by arrow E, and is housed in the housing portion 4. When the housing portion 4 is full, the paper piece can be taken out and discharged.

[0009]

As described above, according to the present invention, all of a large number of thick paper sheet groups can be fed to the upper feeding portion 1 at once without any change, and can be easily fed without taking time and labor as in the conventional case. Then, the supply unit 1 can feed a large amount of the sheet group A into the lower cutting unit 3 while dividing it into small amounts, and the cutting unit 3 can effectively perform the cutting process as in the conventional case. Further, when the sheet group A is supplied to the supply unit 1 and the lid 5 is closed, at least the cutter 2 is activated and the cutting work is automatically started, so that the safety can be further improved. Suitable for a shredder that can be made into a compact structure that can be installed in three layers in the upper and lower to save space, and can supply a large amount of paper sheets A at one time and perform effective cutting processing. It has the features that you can.
