Description

[Technical Field]

[0001] This relates to measuring instruments and drawings in which the starting point 0 position of the numerical value displayed during measurement does not exist or cannot be indicated. [Background technology]

[0002] Conventional measuring instruments displayed the value of 0 with a shift. [Prior art documents] [Patent documents]

[0004] This has caused the following problems: a) At the intersection of the X and Y axes, either four zeros were displayed or one was used for both, which was by no means accurate. b) In a graph where the intersection of the vertical and horizontal X and Y axes is set to 0, it was unreasonable to use the same display for objects with different types of units. C) If the numbers are displayed in duplicate, the 0 display is difficult to draw, understand, and see. D) I wanted to display 0, but there were only unreasonable places to do so. Means to solve the invention

[0005] The invention is characterized in that the central zero position is set as a hole-like space on the graph display or on the measuring instrument.

[0006] The brain now perceives the 0 position, where the X and Y axes intersect, as a hole or gap. When using an L-shaped ruler to measure two perpendicular sides, the corners of the L-shape can no longer be sharpened, so danger can be avoided. -Angle and length are displayed on the same surface at the 0 position, which simplifies the display and makes the relationship between angle and length clear at a glance. You can now draw curved lines by choosing from curves with different radii. -If you trace the bottom edge of a straight line from the desired length position towards the missing point, it will stop at the missing point of 0 and the desired length will be displayed. By combining the angle and length measuring device, angles can be measured without moving the measuring device, figures can be displayed more easily, and the relationship between length and angle can be understood naturally.

[0008] For the sake of convenience, some of the scale lines are omitted in the drawing. Regarding the size of the hole (4) and the notch (6), Select as appropriate. [Figure 1] Figure 1α shows the cross of the X axis (1) and Y axis (3) and the 0 position (2) at the intersection. β shows the state of α as an object, with a hole (4) in the center of the sheet (5) and displayed in space. This is the case when the character 0 is not written. Figure 2 is a plan view of an L-shaped scale, with the corner cut along the cutting line (7) to create a notch (6). The top edge (8) and bottom edge (10) of one of the ruler parts (9) are shown. Figure 3α shows the β in Figure 1 as a circle, with a 360-degree angle (11). The Y axis is shown only at the upper end point above the 0 position. β is a plan view of the upper half of α cut at the X axis position, with an upper and lower side. The 180-degree angle (12) and ruler are shown. Figure 4 is a plan view in which the 90-degree position of the angle gauge and the 0 position of the ruler are the same, with the center of the missing position being the angle section of 180 degrees and the top and bottom edges of the ruler section. A scale line (13) is provided on the angle section. The edge (14) of the vertical width of the ruler section is shown. The bottom end position (17) of conventional measuring instruments has a margin from the bottom end of the scale, but this was removed to set it. In FIG. 5, the upper side is provided in an arc shape, and an arc connecting portion (16) is provided between the upper side and the arc. Figure 6 shows an example of a shape in which the length of the radius (15) gradually decreases from the top edge toward the rear, allowing arcs of various radii to be copied.

[0009] Explain how to use it. The main advantage is that the 0 position is easy to understand, and you can use it by holding the easy-to-hold ruler and aligning the angle part to the right spot. From the ruler's perspective, the angle part allows you to align the missing part of the 0 position with the 0 of the object you want to measure. Since the 0 position is clear, it is easy to measure length. Draw a curved line by selecting from arc curves of different radii. Trace the bottom edge towards the missing part from the length you want to display.
