Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to the improvement of rulers for measuring length, especially those with scales in millimeters. Display of specific scales at a glance by allowing values to be displayed as numbers Concerning the scale of a ruler that made it possible to know the value.

0002

[Conventional technology]

The scale on the ruler has a millimeter scale with 1mm intervals and a centimeter scale with 10mm intervals. There are various sizes, and numbers representing numerical values are often added every 5 mm or every 10. However, other millimeter scales generally do not have numerical values. So The reason for this is that even if numbers are attached to each scale at 1 mm intervals, letters are not printed due to the relationship with adjacent numbers. This is because the size is 1 mm or less, making it difficult for the user to visually recognize it.

0003 However, the number on the conventional scale can only tell 5mm. or 10 mm, and is a value that is not divisible by 5 or 10. In order to know the numerical value according to the number, visually check the numbers attached nearby. The only option is to read the number of the millimeter scale on the millimeter scale, which may result in inaccurate readings. In addition, it is difficult to read when fatigued or for people with poor eyesight. Ta.

0004 There are only a few cases in which numbers have not been added to all scales. Idiots who find it difficult to display numbers that can withstand visual inspection on scales with intervals of less than 1 mm. However, even if small characters of 1 mm or less are added, they are not easy to read. This is because it was difficult. The scales of such conventional rulers are difficult to read, and improvements have been desired.

[0005]

[Purpose of invention]

This invention has sufficient size to withstand visual inspection for all scales at 1 mm intervals. The purpose is to provide a ruler scale that allows numbers to be attached.

[0006]

[Means to solve the problem]

In order to achieve the above purpose, the present invention is based on a ruler with parallel graduation lines at 1 mm intervals. , write a number indicating the numerical value represented by the scale line on the scale line representing 1 mm. Create a hole for the hole and write a number with a size of about 2 mm in the hole. You can also shift the positions where odd numbers and even numbers are written alternately to the left and right. This allows odd and even numbers to be written consecutively without interfering with each other. On a ruler with parallel scale lines at 1 mm intervals, the 0 scale The length of the scale lines attached sequentially in 10 mm increments from the line and the scale lines attached at 1 mm intervals. In addition, among the scale lines attached at 1 mm intervals, the scale lines representing odd numbers and the even numbers are A ruler that has a different length from the scale line it represents and is located on the extension of the end of each scale line. Numbers indicating the length represented by each scale line are written on the surface, and the intervals between the scale lines are It is characterized by being based on units other than the metric system.

[0007]

[Effect]

According to the above solution, the numerical value indicated by the scale line is written as a number on every scale line. Because it is listed on the scale, you can know the value on the scale just by reading the numbers. For this reason , the other scale lines indicate only the numbers marked every 5 or 10 mm. There is no need to do the conventional complicated mental work of knowing the value, just read this number. You can see numerical values at a glance, greatly improving the efficiency of working with rulers, learning, etc. can be done. Moreover, this number can be expanded up to 2mm, so 1mm Visibility can be sufficiently improved compared to the case of .

[0008]

【Example】

The scale of the ruler of the present invention will be explained in detail below based on the embodiment shown in the attached drawings. .

[0009] Figure 1 shows an embodiment of the present invention, in which each scale of a ruler S has a scale line A in units of 1 mm. For each line A, it is possible to number the numerical value represented by that scale line. It is something that

0010 A ruler S with graduation lines in 1mm units has 10, 20, 30, etc. every 10mm. Generally, numbers are written on the 1mm scale line, and no numbers are written on the 1mm scale line. do not have. This makes it difficult to write numbers in a small space of about 1 mm width. This is because the numbers written are too small and difficult to distinguish.

[0011] Therefore, in this invention, numbers are written on the scale line A representing 1 mm as shown in Figure 1. Create a cutout B for insertion, and write a number with a size of about 2 mm in the cutout B. I tried to get into it. Then alternate the positions where you write odd numbers and even numbers on the left and right. By staggering the numbers, odd and even numbers can be linked together without interfering with each other. We are making it possible to continue writing.

0012 With this configuration, for example, starting from 0 mm, 6, 12, 1 at 6 mm intervals. If you want to draw scale lines at equal intervals such as 8, 24, etc., use mental arithmetic (addition or integration). ) to find the desired scale based on the numbers on the mm scale. You can know the position of the line.

[0013] In the embodiment of the present invention explained above, all the scale lines have numbers indicated by the scale lines. Since the values are written as numbers, you can know the value on the scale just by reading the numbers. can. Therefore, using only the numbers marked every 5 or 10 mm as a clue, There is no need to perform the conventional complicated mental work of knowing the value indicated by the external scale line. You can know the numbers at a glance just by reading them, making it more effective when working with a ruler, studying, etc. rate can be significantly improved. Moreover, this number can be expanded to a size of 2 mm. Therefore, visibility can be sufficiently improved compared to the case of 1 mm.

[0014] Next, FIG. 2 shows a second embodiment of the present invention. It has scale lines D, E, and F that are drawn out as shown in FIG. The longitudinal edge C1 of the ruler S When the zero scale is used, the scale line D formed at 10 mm intervals from the zero scale is the most The length is long, and the odd-numbered scale lines E are of medium length, and the even-numbered scale lines F are the longest. It is also short. 1, 2, and 3 (cm) are respectively placed on the ruler surface on the extension of the end of the scale line D. ..., etc., in cm, which is divisible by 10 mm, on the extension of the end of scale line E. Write an odd number on the ruler plane, and an even number on the ruler plane extending from the end of the scale line F. Ru. Note that single digit numbers from 1 to 9 are sufficient to represent odd and even numbers. In addition, a single digit number is preferable due to space limitations.

[0015] The direction in which each number is written is the vertical direction in which each scale line extends, as shown in the figure. Write it down for the purpose. In this case as well, the positions of the areas for writing adjacent numbers are Numbers with a width of 2 mm or more because they are completely offset and do not interfere with each other. can be described. The length of the numbers in the vertical direction must be within the range that does not interfere with adjacent numbers. You can set it even more freely by

[0016] In addition, in the above embodiment, the scale line D every 10 mm is long and represents an odd number. The lengths of scale line E and scale line F representing even numbers are successively shortened, but this is just an example. For example, even if the length of the scale line E representing odd numbers is shorter than the scale line F representing even numbers, good.

[0017] According to this embodiment, the same effect as that of the first embodiment can be obtained. Ru.

[0018] In addition, the ruler with scales of this invention can be used in various ways, such as a rectangular ruler, a triangular ruler, and a tape measure. Applicable to length measurement.

[0019] In addition, although the example above is based on the metric system, it is also possible to use the yard system, etc. It can also be applied to rulers for measuring length in other units.

[0020]

[Effect of the idea] As described above, according to the present invention, all of the scales carved in 1 mm units on the ruler are It is possible to write 2mm size characters using a ruler, making length measurement work using a ruler more effective. can be streamlined.
