Description

[Detailed Description of the Invention] The present invention relates to a ruler that allows marks to be easily and accurately placed on paper or the like according to the scale.

Conventionally, with commonly used rulers that have a scale on the edge of the main body, when marking marks on paper etc. according to the scale, the face of the person marking the mark does not align with the mark. If the scale is on the top, you can accurately mark the mark, but if you mark the mark at a position far from your face, you will have to look at the scale diagonally and write the mark, which may cause the mark to deviate from the scale. is inaccurately written. Therefore,
In order to accurately mark a landmark, it was necessary to constantly position one's face directly above the mark.

Furthermore, since the ruler is flat and thin, it is difficult to grasp and hold, making it difficult to move the ruler smoothly when marking a mark or drawing a line along an edge. It also had various drawbacks, such as the difficulty of holding the ruler in place when marking scales or drawing lines.

The present invention improves the above deficiencies, and includes:
The target location can be easily and accurately marked on paper etc. according to the scale, and
To provide a ruler that can be moved smoothly and can be used without moving when marking a scale or drawing a line.

That is, the present invention is a ruler with a scale on the edge of the main body, and the small hole provided on the extension line of the scale is formed into a tapered part whose diameter decreases from the front side to the back side of the main body. Relating to a ruler in which a presser plate engaged with a part is detachably attached with a screw, and a presser plate fitting hole is provided on the surface of the main body,
The first embodiment of the present invention shown in the accompanying drawings will now be described as follows.

1 is a main body made of synthetic resin or the like, 1a is its front surface, 1b is its back surface, and a scale 3 is provided on the edge 2 of the main body 1. 4 is a notch provided along the edge 2 and on the back side thereof, and 5 is a small hole provided on an extension of the scale 3, and the small hole 5 tapers to a smaller diameter as it goes from the front surface 1a to the back surface 1b. A portion 5a is formed. Reference numeral 6 denotes a side portion of the main body 1, and an engagement protrusion 13 provided on a side portion 7a of a presser plate 7 made of synthetic resin or the like is engaged with an engagement groove 12 provided on the side portion 6. There is. Reference numeral 8 denotes a screw insertion hole provided in the holding plate 7, and the tip of the screw 9 inserted into this hole is screwed into the female screw 10 provided in the side part 6, so that the holding plate 7 can be freely attached to and removed from the side part 6 of the main body 1. It is designed to be installed on. Reference numeral 11 denotes a presser plate fitting hole having the same shape as the cross section of the side portion 7a of the presser plate 7 provided on the surface 1a of the main body 1, so that the presser plate 7 is fitted in an upright state.

When using the present invention, first loosen the screw 9 in the state shown in FIG. Remove the engaging protrusion 13 on the side 7a of the presser plate 7 from the fitting groove 12, and then remove the side 7a of the presser plate 7.
is fitted into a presser plate fitting hole 11 provided on the surface 1a of the main body 1, and the presser plate 7 is attached to the surface 1a of the main body 1 in an upright state as shown in FIG.

Next, when marking a piece of paper or the like according to the scale 3 provided on the edge 2 of the main body 1, insert the tip of a pencil or the like into the small hole 5 provided on the extension line of the scale 3. , the small hole 5 has a tapered portion 5a with a smaller diameter from the front surface 1a of the main body 1 to the back surface 1b.
is formed, so that when the core descends to the center of the small hole 5 along the tapered portion 5a, a mark can be immediately and accurately placed on the paper or the like by the core.

Since the inner diameter of the small hole 5 on the front surface 1a of the main body 1 is larger than the inner diameter of the small hole 5 on the back surface 1b, the core can be easily inserted into the small hole 5 and easily marked. It will be done. Moreover, since the small hole 5 is provided on the extension line of the scale 3, it can be accurately marked.Furthermore, when marking the mark, there is no need to position your face directly above the small hole 5.
It is convenient because the marks can be placed accurately just by inserting the marks inside, and it is also efficient when marking the marks one after another according to each scale 3.

In addition, in the present invention, when in use, the presser plate 7 is attached to the surface 1a of the main body 1 in an upright state as shown in FIG. Furthermore, by holding down the presser plate 7 with one hand, the main body 1 can be firmly pressed onto paper or the like, so that the main body 1 can be used without wobbling. Therefore, marks can be placed more accurately and lines can be drawn more accurately. Moreover, when moving the main body 1, the main body can be moved by grasping the presser plate 7.
can be moved extremely smoothly.

Furthermore, the ruler of the present invention can be used as a substitute for a compass. In this case, first align one of the appropriate small holes 5 with the center of the circle, and then For example, insert one needle tip of a divider or something with a sharp tip such as a pencil lead, and then insert the other small hole 5 located at a distance from the small hole 5 by the length of the radius of the circle. Insert another pencil lead into the other small hole 5 and move it forward or backward in a circular motion to easily draw a circle of the desired size on the paper. You can also draw it as

Also, when the present invention is not in use, the side 7 of the presser plate 7
a from the presser plate fitting hole 11 on the surface 1a of the main body 1, and then engage the engagement protrusion 13 provided on the side part 7a of the presser plate 7 in the engagement groove 12 on the side part 6 of the main body 1. Then, by screwing the tip of the screw 9 into the female screw 10 on the side part 6 of the main body 1, the presser plate 7 is attached to the side part 6 of the main body 1.
Since the main body 1 can be attached thereto, there is no fear that the holding plate 7 will get in the way when the main body 1 is stored in a desk drawer or the like.

Next, in the second embodiment of the present invention, as shown in FIG.
Since the tapered portion 5c has a larger diameter as it goes from the inside 1c to the back surface 1b, the small hole 5
When inserting something that uses ink, such as a pen or fountain pen, to make a mark, even if the ink gets on the inside 1c, there is an effect that the ink will not stick to the paper or the like.
