Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a type of so-called graph paper, which is used for creating characteristic factor diagrams used for quality control and the like.

[Prior art] Conventionally, a cause-and-effect diagram organizes and systematically shows the factors that cause certain problems in fish bones, as shown in Figure 5, and is used to improve quality, increase yield, or solve various problems. , has been used to elucidate the factors.

[Problems to be solved by the present invention] When creating such a characteristic diagram, if you simply add the factors and system line a that you came up with using only a writing instrument, the system lines will become cluttered and the system line It is difficult to follow the lines and understand the factors systematically, so a ruler must be used when drawing the system lines.

For this reason, it has the disadvantage of requiring time and tools to record the factors that come to mind.

[Means for solving the problem] In order to solve such problems, the present invention
A large number of diagonal lines 1 and 2 of a light color or a color different from the color of a specific writing instrument are provided at regular intervals, and in contrast to these diagonal lines 1 and 2, the two diagonal lines 1,
To provide a characteristic factor diagram creation sheet having a structure in which a large number of straight lines 3 of a light color or a color different from the color of a specific writing instrument are arranged at regular intervals and intersect at positions that do not intersect with the intersections of the two.

Note that the term "specific writing instrument" as used herein means a writing instrument used when creating a characteristic factor diagram using the paper of the present invention.

[Operation] With the above configuration, one predetermined diagonal line and one predetermined straight line intersect only at one point, and no other line intersects at this point of intersection.

Furthermore, since each of these lines is light colored or has a color different from the color of a specific writing instrument, it will not be confused with writing using a normal writing instrument.

[Effect of the invention] As a result of this effect, when creating a characteristic diagram, it is possible to draw the system line without clutter by simply tracing the desired line freehand with a writing instrument. It has become possible to create factor diagrams and add factors extremely easily.

In addition, when further organizing the characteristic cause diagram that has been created, the presence of unused lines makes it easy to judge the suitability of the length and position of the system lines, creating a more easily understandable characteristic diagram. It becomes easier to do so.

Next, embodiments of the present invention will be described based on the drawings, but the present invention is not limited to these embodiments.

In addition, FIG. 1 is a plan view showing one embodiment of the paper of the present invention, FIG. 2 is an enlarged plan view of the line forming portion of FIG. 1, and FIGS. 3 and 4 are line forming of another embodiment. An enlarged plan view of the portion and FIG. 5 are explanatory diagrams showing an example of a characteristic factor diagram drawn on a sheet of paper.

[Example] In FIG. 1, 4 is a base paper, which is a high-quality paper,
This can be tracing paper or OHP film.

In FIG. 2, 1, 2 and 3 are lines printed on the surface of the base paper 4, which are yellow, red,
It is painted in a color different from the color of the writing instrument normally used, such as blue, persimmon yellow, green, or light gray, or in a color that is clearly lighter than the color of the writing instrument used.

Diagonal lines 1 and 2 intersect straight line 3 at an included angle (θ).

Figure 2 shows the included angle (θ) set to 45°, and Figure 3 shows the included angle (θ) set to 60°, but of course the included angle (θ) is not limited to these, for example, 30°, 75°. It may be set at an appropriate angle such as 80° or 80°.

The diagonal lines 1 and 2 have opposite inclination angles, and their intersection is set at the center of the distance L between the straight lines 3.

The distance L between the straight lines 3 may be set arbitrarily, but if the size of the base paper 4 is A3 or smaller and is used on a tabletop, approximately 1 to 5 mm is appropriate. Also,
If the size of the base paper 4 is A3 or larger and is used for presentations, a suitable size is about 4 to 20 mm.

The lines 1, 2, and 3 may all be the same color, but for example, the diagonal lines 1, 2 and the straight line 3 may be different colors, each may be a different color, or similar lines may be used. They can be combined into various types depending on the purpose, such as making every other one or every plurality of them a different color.

Also, all the lines may have the same thickness, but for example, diagonal lines 1 and 2 and straight line 3 may have different thicknesses, each line may have a different thickness, or lines of the same type may be made to have the same thickness. They can be combined into various types depending on the purpose, such as having different thicknesses for every book or every set of books.

Also, only the straight line 3a passing through the center of the base paper 4 can be made to have a completely different thickness and/or color from the other lines, so that the center _a0 of the system line can be easily marked, or the same color as the writing instrument can be used. The center _a0 of the system line may be formed in advance with a certain color and/or density.

Furthermore, a straight line 5 that is perpendicular to the straight line 3 may be added as shown in FIG. 4 to make it easier to draw a frame surrounding the main factor entry area and the theme entry area.

Further, the intersection points of the diagonal lines 1 and 2 may be set to exist between every other or every plurality of the straight lines 3.
