を裁断くず収納スペースで受けるようにしていた。Conventionally, as shown in Fig. 7, this type of cutting device has a box-shaped structure with a cutting space B in the upper part and a cutting waste storage space C in the lower part, and is installed on the office floor -F. In the cutting space B of this cutting device A, there is a tooth section in which a plurality of rotating teeth provided on each of a pair of rotating shafts rotate in opposite directions while being in sliding contact with each other between the rotating shafts. A cover E having an insertion opening corresponding to this toothed part is placed so that documents, etc. can be inserted through the insertion opening of the cover E, and the shredded scraps can be received in the shredded scrap storage space through the crest. I was doing it.

型の裁所ｖ装置を開発することが課題となされてきた。However, in the above-mentioned conventional cutting device, the width of what can be inserted is limited due to the insertion opening and the fact that the two ends of the rotation shaft of the teeth are intersected by a drive mechanism, rotation bearing, etc. Drawing paper that exceeded the width of the insertion slot had to be folded in half, and even wider paper had to be folded more often or the paper surface had to be torn to make it wide enough for insertion. Furthermore, considering the case where multiple folded documents are inserted, either increase the power of the device or limit the number of sheets that can be cut at a time.
Also, since the main body of the device needs to be enlarged, it is inconvenient and uneconomical, such as not being able to be used freely on an individual level when and where needed. Therefore, it has been an issue to develop a compact court v-device that can be carried freely without limiting the width of documents etc. that can be inserted.

題を解消するものである。The present invention has been made in consideration of the above-mentioned conventional problems, and includes a tooth portion in which a plurality of rotating teeth provided on each of a pair of parallel rotating shafts are in rotatable sliding contact with each other between the rotating shafts; a drive section located at one end of the tooth to cantilever support each of the rotating shafts and drive each of the rotating shafts to rotate in opposite directions, the other end of the tooth being open to the outside. The purpose of the present invention is to provide a cutting device characterized by the following, thereby solving the conventional problems.
つぎに、本発明を第１図から第６図に示す実施例に基づ

ている。Further, each end of the rotating shaft 41 of the tooth portion 4 is pivotally supported by a gear box 51 as shown in FIG. ing. Then, the driving force of the motor 50 is transmitted through gears a, b, c, and d arranged in the gear box 51 in order to the gear e located at the end of one rotating shaft 41 to rotate the rotating shaft 41. The other rotating shaft 41, which has a gear f meshing with the gear e at its end, also rotates. It is designed to bite and cut paper or other objects inserted from above.

The other end of each rotating shaft 41 facing the gear box side is rotatably supported by the bearing 30 of the lower case 3, and the frontage,! A toothed portion 4 in which a rotating shaft 41 is arranged on each of the bearings 30 provided with 118 in between.
The other end, which is not connected to the drive section 5, is r:Al tli to the outside of the tooth section 4 in the longitudinal direction. In the lower case 3, a battery 9 supplies power to the motor 50.
is stored in the storage section 31 and covered with the rooster 32.

Although the method of sliding contact is reversed, the present invention is not limited to this, and various sliding contact patterns can be adopted as appropriate. Further, although the case is box-shaped, the case may be provided with a grip portion so that the entire body can be supported by hand. Furthermore, the driving source is not limited to batteries, but can also be powered by a household power source or manually operated.

It is only necessary to repeat the operation of inserting the side part of the paper piece from the insertion port 6 to the discharge lower. In order to reinforce the opening 8, as shown in FIG. 4, a substantially U-shaped reinforcing arm 10 may be detachably and slidably attached so as to straddle the opening.

In this case, a slide letter guide 20 may be slidably provided near the opening side of the insertion port 6, or a concave letter guide 21 may be provided on the opening side as shown in FIG. By applying the sealed letter to the letter guide or the letter guide, the positioning of the sealed letter becomes easy and the 1N side part can be opened reliably.

である。As described above, according to the present invention, the cutting device includes a tooth portion in which a plurality of rotating teeth provided on each of a pair of parallel rotating shafts are rotatably inscribed in each other between the rotating shafts; and a drive section located at one end to support each of the rotating shafts in a cantilever manner and drive the rotating shafts so that they rotate in opposite directions, and the other end of the toothed portion is open to the outside. There is no longer a need to limit the width of the meat, etc. to be cut, and there is no need to increase the power to handle items that have been folded multiple times. In addition, the other side of the paper strip can be cut simply by holding the side of the paper and inserting it from above the teeth, and the operation is easy, so even if the number of rotating teeth is reduced, repeated cutting operations are easy. This makes it possible to achieve low output and miniaturization. Therefore, by reducing the cutting width, we are able to provide a compact and low-cost cutting device that can be stored in a familiar place, such as a desk or bag, and the battery type does not require external power, so it can be used overseas. You will be able to carry and use it anywhere. It also has excellent practical effects, such as being able to cut the desired sidewall of a piece of paper and also being used as a letter opener.
