Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention is mounted on an outlet for discharging a loaded roll-wound paper sheet in an automatic drafting machine or the like, and continuously discharges from the outlet. The present invention relates to a paper sheet cutter for cutting a used paper sheet.

[Prior Art] Conventionally, for example, in an automatic drafting machine or a device with a recording device that evaluates and measures the performance of various materials and products, roll-shaped paper is used to record numerical values, diagrams, graphs, etc., respectively. The seat is loaded. Then, in order to cut the paper sheet continuously discharged from the exit portion into an appropriate length, a cutter that is in a straight line along the width direction of the paper sheet is attached to the exit portion of the paper sheet. Therefore, the cutter has a sharp blade edge exposed and protrudes outward, and the discharged paper sheet is pulled downward to cut the paper sheet at the blade edge portion.

[Problems to be solved by the invention] A conventional cutter of this type is installed at a place where a human finger or the like is easily touched, and the cutting edge is exposed. However, improvement in safety is strongly desired. In addition, it is difficult to cut a wide paper sheet by applying a paper sheet to the cutting edge and tearing it, and if you try to cut it quickly, the cut will often come off the cutting edge and break the necessary part. .

Therefore, an object of the present invention is to provide a paper sheet cutter that is safe and can be cut easily and quickly.

[Means for Solving the Problems] In order to achieve such an object, the paper sheet cutter of the present invention has a sharp pointed portion such as a ballpoint pen on the side surface of a hard and elongated base material having a distance longer than the width of the paper sheet. The groove is formed linearly along the longitudinal direction of the base material so that the groove has a width enough to fit and a required depth.

[Operation] The paper sheet cutter of the present invention configured as described above,
In various types of equipment, the paper sheet is mounted and fixed at the exit portion from which the loaded paper sheet is discharged, along the width direction of the paper sheet and with the groove facing the outer surface.

Then, the paper sheet after recording is continuously discharged from the outlet portion, but when it is hung down on the front surface of the paper sheet cutter, a hard and pointed portion like the tip of a ballpoint pen is placed on one side of the paper sheet. The paper sheet is pressed by pushing the sharp portion into the groove from the end, and straightly cut by moving in a straight line toward the other side end as it is.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 is an automatic drafting machine, and a main body 3 is mounted on legs 2 and 2.
Also, the operation table 4 is installed, and the rolled paper sheet 5 is loaded (not shown) in the main body portion 3, and the recorded paper sheet 5 continues from the outlet portion 6 on the side surface of the main body portion 3. It is then discharged and naturally hangs down as shown in FIG.

Thus, the paper sheet cutter according to the present invention is made of a base material 7 which is hard and has a rectangular cross section having a distance longer than the width of the paper sheet 5, and a tip pointed portion such as a ballpoint pen is provided on the front surface 7a of the base material 7. A groove 8 having a width enough to be fitted and a depth having a slight margin in a state where the sharp portion is fitted is provided linearly along the longitudinal direction of the base material 7, that is, this embodiment. Then, one concave groove 8 having a V-shaped cross section or a plurality of concave grooves 8 are continuously provided.

In addition, the paper sheet 5 is provided at the outlet 6 of the automatic drafting machine 1 which is constructed with the opposite side of the surface provided with the concave groove 8 as a mounting surface.
The paper sheet 5 is mounted on the front surface of the side wall 9 for receiving the paper sheet 5 in a horizontal position along the width direction.

Then, as shown in FIG. 2, the paper sheet 5 hanging on the front surface of the paper sheet cutter is applied to the front surface 7a, and the tip of a ballpoint pen or the end of a ruler is inserted into one of the concave grooves 8 from one end of the paper sheet 5. If the pointed portion of the paper sheet 5 is pushed in from the upper surface of the paper sheet 5 and then moved in a straight line toward the other side end, the paper sheet 5 moves in the groove 8 by the pointed portion of the groove. Cut along 8 and cut. As described above, as long as a plurality of grooves 8 are continuously provided, any groove 8 may be used. Therefore, it is not necessary to insert the tip of the ballpoint pen into the groove 8 as in the case of only one groove.

FIG. 4 shows another embodiment of the concave groove 8 of the paper sheet cutter, and FIG. 4 (a) shows only one concave groove 8 having an arcuate cross section in the center. Further, FIG. 2B shows a taper surface 10, 10 recessed toward the center on the front surface, and a single groove 8 having the same shape as that of FIG. By providing the tapered surfaces 10 in this manner, it is convenient to serve as a guide into the groove 8. These are typical examples of the concave groove 8, and various shapes other than those shown in the drawing are also applicable.

The paper sheet cutter of the present invention is the automatic drafting machine 1 described above.
However, the present invention is not limited to the above, and can be widely applied as long as it is a device equipped with an automatic recording device that evaluates and measures the performance of various materials and products, and that uses a rolled paper sheet.

[Advantages of the Invention] As described above, the paper sheet cutter of the present invention has a configuration in which a concave groove of an appropriate shape is provided on the side surface of the base material, so that a sharp blade portion is exposed to the outside as in the conventional case. There is no such thing and it is extremely safe in use. In addition, the paper sheet hanging on the front surface can be cut simply by inserting the pointed tip of a ballpoint pen into the concave groove and moving it in a transverse direction, which is faster, easier, and more accurate than the conventional one. Especially effective for cutting wide paper sheets.

Furthermore, the material to be used is not particularly limited, is structurally simple, can be manufactured with high productivity, and has an advantage in economical efficiency.
