Abstract

<P>PROBLEM TO BE SOLVED: To prevent a paper bundle from being dislocated at the time of cutting the paper bundle which is thick. <P>SOLUTION: A cutting blade 1 is configured with two angles, a normal angle 11 and a very thin angle 12 formed from the opposite surface. This prevents the paper bundle from being dislocated at the end, and it is possible to cut the paper in a specified length. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

事務所の紙束切断。
厚い紙の束を切断するときの紙ずれを防ぐものである。 Cutting paper bundles in the office.
This prevents paper misalignment when cutting a thick paper bundle.

一般に事務所などで使われる、紙の切断機には鋭角片面の刃がついていて、厚い紙などを平行に押し切ろうとするときに、ずれないように紙の束を強く押し付けてから切るようになっている。 Generally used in offices, etc., paper cutting machines have sharp single-sided blades, and when trying to push through thick paper etc. in parallel, press a bundle of paper strongly so as not to slip and then cut it It has become.

しかし、実際にはこの力を十分強くすることは難しい。とくに、事務所などでは人力でかけられる力程度でないと安全の不安が生じる。
そのため図２のように、押し切ると共に下の紙が刃の方にずれていってしまうことがおきやすい。 However, in reality, it is difficult to make this force strong enough. In particular, in offices, there is a concern about safety if it is not at the level of human power.
For this reason, as shown in FIG. 2, it is easy for the lower paper to be displaced toward the blade as it is pushed out.

このため、刃自体を紙がずれにくい形状にしようとしたものである。 For this reason, the blade itself is intended to have a shape in which the paper is not easily displaced.

図３のように、刃１の角度を通常の角度１１の他に、反対面からのごく薄い角度１２をもたせる。
または図４のように、刃１の角度１１の反対がわに角度１２をもった刃２を取りつける。 As shown in FIG. 3, in addition to the normal angle 11, the blade 1 has a very thin angle 12 from the opposite surface.
Alternatively, as shown in FIG. 4, the blade 2 having an angle 12 opposite to the angle 11 of the blade 1 is attached.

その結果、図３の左端のように紙の束の端がずれないので、紙を一定の長さで切ることができる。 As a result, the end of the stack of paper does not shift like the left end of FIG. 3, and the paper can be cut at a certain length.

実施例としてはふつうの切断機に取り付けるだけなので省略する。 Since it is only attached to a normal cutting machine as an Example, it abbreviate | omits.

紙束を押しつける力をあまり強くしなくてもよくなるので、安全性が増す。 Safety does not need to be increased so much that the paper bundle is pressed.

通常の刃と角度と紙束の位置関係。The positional relationship between the normal blade, angle and paper bundle. 通常の刃が押し切っていくにつれ、紙がずれていくようす。As the normal blade pushes out, the paper will shift. 本考案のように刃の角度をつけた場合。When the blade is angled as in the present invention. 本考案の変形。A variant of the invention.
