Abstract

PROBLEM TO BE SOLVED: To solve the problem that a part at an operator's hand becomes shady when the operator reads out a fine graduation on a triangular scale and that, when a dimension to be measured is situated at the operator's front, the graduation is hard to read out because the operator's face must be brought close or a drawing must be moved. SOLUTION: When the moving mark is formed on the triangular scale, the graduation can be read out in front of the operator's eyes in such a way that the graduation which becomes shady or which is situated at the operator's front and hard to read out is aligned with the mark.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mark attached to a scale on a triangular scale.

[0002]

2. Description of the Related Art A conventional triangular scale shape has a triangular shape of 1/100, 1/200, 1/30 as shown in FIG.
The difference is 0, 1/400, 1/500, 1/600, etc., and the scale memory is engraved. When measuring the length of the drawing, apply a triangular scale to the drawing and bring the face closer to read the numerical value. I was out.

[0003]

However, according to the above conventional technique, the scale is read by pressing the triangular scale against the drawing, when the scale is difficult to read, the face is brought closer, the drawing is moved, and the like. I was moving my body and reading the numbers on the scale. Therefore, according to the present invention, by attaching a mark that moves across the groove of the triangular scale, it is possible to press the drawing and move the mark to the place where you want to measure, and then bring it to your hand to read the scale. This is an issue.

[0004]

In order to solve the above-mentioned problems, the invention of claim 1 is a mark characterized in that it moves by sandwiching a groove of a triangular scale. The invention of claim 2 is a mark characterized in that the mark is made easy to read by forming a convex lens around the mark.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION One embodiment of the present invention is shown in FIG. Triangular scale body Figure 2 shows a concave part 1 in the center.
There is, and it is sandwiched by the convex part 2 of the moving mark, and it is slid with a finger to align the mark 3 with the scale.

[0006]

Other Embodiments In the embodiment shown in FIG. 1, the marks are provided only on one scale, but the marks may be provided on both scales.

[0007]

According to this embodiment, by sliding the pointer 4 and aligning the scale, it becomes possible to bring the hand to the hand and read the scale.
