Abstract

Kind Code: A1 At present, the degree of freedom in reducing and enlarging figures and the like is increasing due to the use of computers, printers, and the like. The present invention provides a scale ruler that can handle any scale in an analog manner by reading the intersection of lines on the ruler. A flat plate A has vertical and horizontal orthogonally spaced lines and an oblique proportional line Bc. With the upper left as the origin, the horizontal reference line is sequentially graduated. The vertical fractional scale corresponds to the scale value at that position, and the intersection of the proportional line and the horizontal line is the dimension corresponding to the scale scale. The horizontal reference line reading along is the dimension on the reference scale. [Selection drawing] Fig. 1

Description

The present invention relates to a ruler for reading the scale of figures, etc., by orthogonal vertical and horizontal lines and proportional lines.

At present, when reading the scaled dimensions of a figure or the like, the current situation is to read the scaled value using a triangular scale or the like, or to calculate the ratio of the measured dimensions in other cases.

The present invention seeks to solve such problems.
In order to achieve the above purpose, a plurality of horizontal and vertical parallel lines are arranged on a plane plate, and the upper left 1/100 scale point is set as the origin, and these horizontal reference lines are sequentially scaled.
The scale on this horizontal line corresponds to the figure size.
The vertical fractional scale corresponds to the scale value at that position.
The intersection of the diagonal proportional line and the horizontal line is the dimension corresponding to the scale scale (diagonal scale reading).
Also, it is the dimension when the reading of the upper reference line along the oblique proportional selection from the intersection is 1/100 of the reference scale.

By using this reduced scale ruler, it is possible to see the dimensional value of figures whose reduced scale is unknown on this ruler as a reduced scale value or a reference scale (1/100).
At present, it is common to read a figure or the like whose scale is specified with a ruler whose scale is limited, or to calculate the ratio by calculation.
The present invention can be carried out by applying this ruler to the figure. In addition, it is an analog ruler that can correspond to any reduced scale scale on the ruler, and can correspond to figures freely reduced in size through computers, printers, etc.

1 is a plan view of the present invention; FIG.

Vertical and horizontal lines and diagonal proportional lines are drawn on a flat plate made of plastic or the like at equal intervals, and scaled dimensions are read.

Description of the drawing Red line part Unknown scale, in the case of line segment dimensioning (assuming scale length a = 8) Place a line segment of length 8 at the position that matches the proportional line, scale value passes through the intersection with the unit line From the scale reading 16 on the 1/100 scale reference line of the proportional line, it becomes 1/160.
Blue line The position of the horizontal line that passes through the point of intersection with the read-out unit line by following the proportional line from the position of the dimension-corresponding reference horizontal line at the 1/100 scale scale position is the scale scale value line.
If there is no scale indication, align the measurement dimension line with the position of the proportional line, and obtain the scale value from the horizontal line and unit line at that position.
If there is a reduced scale indication, perform on the reduced scale horizontal line.
