Description

  The present invention relates to a ruler.

  As a ruler that cuts paper, draws lines on paper, or makes dots, it is a thin flat plate made of transparent resin and a rectangular shape that is elongated in the left-right direction, and has a grid scale There are some (see, for example, Patent Document 1). With such a ruler, the ruler is positioned with respect to a desired reference point on the paper surface by means of a grid scale, so that a location that is a desired distance away from the reference point on the paper surface can be accurately cut, or a line can be drawn to the above location. Can be drawn accurately.

  By the way, in the above case, it is necessary to make the ruler scale as fine as possible in order to perform cutting and line drawing accurately. However, if the ruler scale of the ruler is made too fine, lines, figures, patterns, characters, etc. on the page will be complicated with the ruler grid, and the ruler cannot be positioned easily and accurately with respect to the reference point on the page. There was a problem with.

  An object of the present invention is to provide a ruler that can be easily and accurately positioned with respect to a reference point on a paper surface in a short time.

In order to achieve the above object, the present invention is characterized in that, in a ruler that is transparent and has a grid of many grids, an inner registration mark is disposed in the center of the grid. It is in the point.
In addition, it is a hard and transparent flat plate shape, is a rectangular shape elongated in the left-right direction, has a scale display part on the upper surface and / or the lower surface, and a vertical line in the front-rear direction and a left-right direction on the scale display part. By arranging horizontal lines in the direction, an inner registration mark may be arranged at the center of the square in a ruler in which a grid of many squares is arranged.
The shape of the inner registration mark may be +, x, or *.
Further, an outer registration mark that does not overlap with the inner registration mark may be arranged at the center of the side part around the square.
In addition, an outer registration mark may be configured by arranging a short line segment in the central part of the side of the grid in an orthogonal shape.
Furthermore, a dimensional scale may be provided on the scale display section.

  According to the present invention, the ruler can be easily and accurately positioned with respect to the reference point on the paper surface in a short time.

It is a top view which shows an example of embodiment of this invention. It is an enlarged view of the A arrow part of FIG. It is an enlarged view of the B arrow part of FIG. It is an enlarged view of the C arrow part of FIG. FIG. 3 is a cross-sectional view taken along line DD in FIG. 2.

  Hereinafter, an example of an embodiment in which the present invention is applied to a straight (straight) ruler will be described with reference to the drawings. The ruler has a thin flat plate shape made of a transparent hard resin, and has a rectangular shape elongated to the left and right. As the hard resin, for example, an acrylic resin or a vinyl chloride resin is used. The whole of the lower surface of the ruler except for the right side is the scale display portion 1 and the right end of the lower surface is the outer dimension scale 2, which is formed by printing with black ink or the like. In addition, the scale display part 1 and the outer dimension scale 2 may be arrange | positioned on the upper surface of a ruler, or both an upper surface and a lower surface. A suspension hole 3 is vertically formed between the ruler scale display portion 1 and the outer dimension scale 2 so as to penetrate therethrough.

  The scale display unit 1 has a rectangular shape that is elongated in the left-right direction. The scale display unit 1 has vertical lines 5 in the front-rear direction that are parallel to each other at regular intervals, and are parallel to the intervals and orthogonal to the vertical lines 5. A large number of horizontal lines 6 in the left-right direction are arranged, and a large number of grids (square squares) 7 are formed by the vertical lines 5, the horizontal lines 6, and the front and rear edges and the left edge of the scale display portion (ruler) 1. Thus, a grid graduation 8 is configured. The interval between the vertical line 5 and the horizontal line 6 is 10 mm, and the grid 7 is a 10 mm grid. An inner registration mark 9 is disposed at the center (position) inside the grid 7, and the center (position) of each side 10 around the square of the grid 7 does not overlap with the inner registration mark 9 (no interference). ) An outer registration mark 11 is provided. These register marks 9 and 11 are used as positioning marks and marks in this specification. The inner registration marks 9 are, for example, +, x, *, and the like. Further, in the illustrated example, a short line segment 12 in the front-rear direction or the left-right direction orthogonal to each side part 10 is disposed at the center of each side part 10, and the line segment 12 and each side part 10 provide an outer side. A registration mark 11 is configured. Note that the outer registration mark 11 may be configured by deleting (omitting) a part of each side part 10 and arranging, for example, +, x, *, etc. in the part. Further, the outer registration marks 11 are not formed on the front and rear edge and the left edge of the scale display part (ruler) 1 and the right edge of the scale display part 1.

  The front and rear dimension scales 14 and 15 in 1 mm increments are arranged at the front and rear ends of the scale display unit 1, and the left and right dimension scales 16 and 17 in 1 mm increments are also provided on the left and right ends of the scale display unit 1. Is arranged. In addition, the front and rear end portions of the vertical line 5 are partially deleted (omitted), and dimension indication numerals 18 and 19 indicating the dimensions for the front and rear dimension scales are disposed in the deleted portion. The dimension display numerals 18 for the front dimension scale are arranged in the order of 1 to 29 from the left to the right. The dimension indication numbers 19 for the rear dimension scale are arranged in the reverse direction so that the rear side of the ruler is on the upper side, and are arranged in the order of 14 to 0 to 14 from the left to the right. Yes. The left and right dimension scales 16 and 17 are also provided with dimension display numerals 20 and 21 indicating the dimensions. The dimension display numerals 20 and 21 are disposed in the order of 1 to 5 from the front to the rear. ing. Note that the outer registration marks 11 are not disposed on the vertical lines 5 every 5 cm from the left end, and instead, the inner dimension scale 22 in 1 mm increments is disposed.

  The outer dimension scale 2 is also a dimension scale in 1 mm increments, and dimension indication numbers 24 indicating the dimensions are also arranged on this scale. The dimension indication numbers 24 are arranged so that the rear side of the ruler is on the upper side. Further, they are arranged in the opposite direction. The dimension display numerals 24 are arranged in the order of 1 to 6 from the rear to the front.

  The upper end of the upper surface of the ruler is an inclined surface 26 that moves downward as it moves forward.

  According to the above configuration example, when cutting the paper, drawing a line on the paper surface, or hitting a dot, the ruler is positioned with respect to a desired reference point (point) on the paper surface, and each dimension scale 2 , 14 to 17, and 22 can be used to accurately cut a location that is a desired distance from the reference point on the paper surface, accurately draw a line at the location, or place a point at the location. .

  In the above case, when the ruler is positioned with respect to the reference point on the paper surface, the ruler can be positioned using not only the ruler grid scale 8 but also the inner registration mark 9 and the outer registration mark 11. The ruler can be accurately positioned without being too fine (that is, as shown in the figure, the grid 7 can be made as large as a 10 mm grid). Therefore, there is little possibility that the line, figure, pattern, character, etc. on the paper surface and the ruler grid 8 will be complicated, and the ruler can be easily and accurately positioned with respect to the reference point on the paper surface.

  In the above configuration example, the present invention is applied to a straight ruler, but the present invention is also applicable to a triangular ruler and other rulers.

  The present invention can be applied to a ruler for cutting paper, drawing a line on a paper surface, or hitting a dot.
