Description

[Detailed description of the invention] This invention relates to a paper cutter, and its purpose is to cut out or cut out required parts of newspapers, magazines, etc.
To provide a cutter which can easily cut out only one sheet of paper without requiring an underlay, without damaging the paper on the lower side, and is safe even if it is touched by fingers or the like.

Conventionally, when cutting a sheet of paper as described above, it is cumbersome to use scissors, and it is especially difficult to cut in a straight line.

Another method is to use the edge of a knife or a so-called cutter to cut out the paper by placing it against a ruler, but if you use the cutter to cut multiple stacked sheets of paper, the edge of the knife will cut through the paper below and even other papers. result. Therefore, there is the inconvenience of having to lay down an underlayment that may cause damage when cutting.

This invention solves this inconvenience, and when you pull it against a paper surface, only the topmost sheet is always cut, and it can be used safely without damaging the paper surface or desk underneath, which is surprising. To provide a cutter whose cutting edge does not act on a resilient non-flat surface such as a finger or the like and does not cause any damage when pulled.

Hereinafter, a detailed explanation will be given with reference to the drawings. FIG. 1 is a front view and FIG. 2 is a bottom view. The main body 1 is an elongated plate-shaped body made of, for example, synthetic resin, and usually has a wall thickness of about 2 to 3 mm and a length of about 6 to 7 cm.
The base 2 in the longitudinal direction is a straight line, and the opposite side 5 is an inclined side, and it is preferable for use that one end is made wider overall. As shown in FIG. 2, the thick surface of the bottom side 2 is very slightly inclined toward both sides of the main body, with the center straight line 3 along the longitudinal direction being the highest point (see FIG. 4, 2').

Reference numeral 4 denotes a blade piece embedded parallel to the thickness near one end of the main body 1, and as shown enlarged in FIGS. 3 and 4, the corner 4' of the blade edge is aligned with the center line. 3 and is integrally buried and fixed in a very small protruding state. Although the degree of this protrusion is greater than the thickness of normal paper, it is very slight and is visible to the naked eye.

To use the cutter of this invention, place the paper to be cut flat on a desk or other flat surface,
If you press the entire bottom side 2 of the main body 1 against the paper surface and stand it vertically, that is, keep the entire length of the center straight line 3 in contact with the paper surface, and pull it in the direction shown by the arrow in Figure 1, the corner 4' of the cutting edge will touch it. Only the single sheet of paper that has been cut is cut, and the paper underneath or anything underneath the paper is not damaged in any way. The center line 3, which is formed slightly protruding along the center of the wall thickness of the bottom side 2, creates a linear creasing effect on the paper surface when the entire cutter body is pressed and pulled against the paper surface. Since the cutting edge is guided along the straight line and the cutting edge is reliably guided along it, straight cuts can be made very easily and reliably by free hand. Note that curved cuts can also be made freely by moving the plane of the paper by pressing the vicinity of the upper part where the cutting edge 4 is located with a fingertip.

Further, according to the present invention, since a minute cutting edge exists near the end of the center straight line 3 of the straight base 2 having the above-mentioned structure, the entire length of the center straight line 3 is pressed in contact with the plane on the average. The cutting edge works reliably only when moving, so it is safe to handle.

In this way, according to the present invention, it is possible to cut only the desired sheet of paper without damaging the paper or other objects underneath the desired paper, and it is suitable for cutting out newspapers, magazines, and other documents. It is suitable and safe, has a simple structure, is easy to use, and has extremely large practical effects.
