[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1A is a plan view showing a ruler as one embodiment of the scale according to the present invention, and FIG. 1B is a cross-sectional view taken along the line AA in FIG. In these figures, the main body 1A of the ruler 1 is formed from a transparent body, for example, a transparent resin such as transparent plastic, and is formed in a rectangular plate shape.

On the upper surface of one end of the ruler body 1A in the longitudinal direction, a tapered surface 1a that is inclined from a higher position to a lower position as it goes from the inside to the outside is formed. It is formed by printing. Here, a transparent lens portion 3 extending linearly is formed on at least a part of the non-scale forming portion of the ruler body 1A.

In the present embodiment, the transparent lens portion 3 is formed in a straight line crossing along the longitudinal direction at an intermediate position of a length orthogonal to the longitudinal direction of the ruler body 1A. In this case, the transparent lens portion 3 is a convex lens portion that curves and protrudes from the surface side of the ruler main body 1A, and is integrally formed when the ruler main body is molded with the transparent resin.

2 to 7, in all cases, the transparent lens portion 3 is formed in a straight line crossing along the longitudinal direction at an intermediate position of a length in a direction orthogonal to the longitudinal direction of the ruler body. 14 shows a modified example of a form such as a scale in the case. That is, the ruler 1 of FIG. 2 has the scales 2 formed on the upper surfaces of both side ends in the longitudinal direction of the ruler body 1A.

In the ruler 1 shown in FIG. 3, the scales 2 are formed on the upper surfaces of both side ends of the ruler body 1A in the longitudinal direction, and the scales 2 are provided at both ends and an intermediate portion between the both ends. It is formed. Further, in the ruler of FIG. 4, in addition to the scale 2 of the ruler 1 of FIG. 3, a square mesh 4 is formed in a portion excluding the position where the transparent lens portion 3 is formed between the scales 2 on both sides.

The ruler of FIG. 5 is different from the ruler 1 of FIG. 4 in that the scales 2 at both ends and an intermediate portion between the both ends are eliminated. In the ruler 1 shown in FIGS. 6 and 7, dots or cross patterns 5 are arranged at predetermined intervals in place of the meshes 4 of the ruler 1 shown in FIG.

In each of the above embodiments, the transparent lens portions 3 are each formed in a line in a straight line crossing along the longitudinal direction at an intermediate position in the length direction perpendicular to the longitudinal direction of the ruler body 1A. Although the transparent lens portion may be provided in a plurality of rows, as shown in FIG. 8, the transparent lens portion may be shifted to one of the intermediate position and the intermediate position in the direction perpendicular to the longitudinal direction of the ruler body 1A as shown in FIG. At the position, the shape may be formed in a straight line crossing along the longitudinal direction.

Further, as shown in FIG. 9, the transparent lens portion 3 may be formed in a straight line crossing along a direction perpendicular to the longitudinal direction of the ruler main body 1A. Alternatively, as shown in FIG. 10, the transparent lens portion 3 is formed by traversing along the longitudinal direction of the ruler main body 1A and a portion 3A formed along the direction orthogonal to the longitudinal direction of the ruler main body 1A. The formed portion 3B may be formed so as to form a substantially cross shape. In this case, there may be only one substantially cross-shaped portion.

According to the ruler 1 having such a configuration, since the transparent lens portion 3 extending linearly is formed in at least a part of the non-scale forming portion of the ruler body 1A, for example, the small lens portions provided in a row in a book or the like are provided. In order to enlarge a character, the ruler body 1A simply slides up and down or left and right along the character string, and the transparent lens unit 3 moves along the character string to enlarge the entire character string. This is extremely convenient because it is not necessary to move the ruler vertically and horizontally to fit the conventional magnifying glass-shaped circular lens part to the part to be enlarged.

Further, since the transparent lens portion 3 is formed in the non-scale forming portion of the ruler main body 1A, the transparent lens portion 3 can be used without the printed scale 3 being in the way. In particular, in the ruler 1 of FIG. 10, a portion formed transversely along the longitudinal direction of the ruler main body 1A and a portion formed transversely along a direction orthogonal to the longitudinal direction of the ruler main body 1A. Are formed so as to form a substantially cross shape, so that there is an advantage that it is not necessary to change the direction of the ruler when the character strings are arranged vertically and horizontally.

[Effect of the invention]

 As described above, according to the inventions according to the first, third, and fourth aspects, when the transparent lens portion is a convex lens portion (the invention according to the seventh aspect), the transparent lens portions are arranged in a line in a book or the like. When viewing small characters in an enlarged manner, simply slide the scale body up and down or left and right along the character string, and the transparent lens moves along the character string to enlarge the entire character string. Therefore, there is an advantage in that the usability is excellent and the scale is not in the way and the transparent lens portion can be used without any trouble.

According to the invention of claim 2, since the transparent lens portion is formed at a plurality of locations, a character string or the like can be enlarged at each of the plurality of transparent lens portions, which is more convenient.

According to the invention of claim 5, it is not necessary to change the direction of the scale when the character strings are arranged vertically and horizontally in a mixed manner, which is excellent in usability.
