Abstract

Two-dimensional coordinates are often used to measure positions of application forms. To make a mark at 19.5cm from the top and 16.3cm from the left on a form, we usually have to use a ruler twice. However, by using the two-dimensional ruler, we can get two- dimensional coordinates with one-time-operation. This disclosure shows how the above idea is resolved. Transparent plastic templates ruled in squares (like a cross-section paper) are used for these purposes. However the ruled lines on them are not accurate enough because the main purpose of them is not to measure precisely. If there are many cross-sectional lines, in addition, it is difficult to identify each line. It is possible to get two-dimensional coordinates at once by using drafting machines, but they are so expensive and are not portable. The two-dimensional ruler is aiming for easing restrictions of plastic templates. Every ruled line is, therefore, accurate enough and easily viewable.

Two-dimensional Ruler

Two-dimensional coordinates are often used to measure positions of application
forms. To make a mark at 19.5cm from the top and 16.3cm from the left on a
form, we usually have to use a ruler twice. However, by using the
two-dimensional ruler, we can get two- dimensional coordinates with
one-time-operation. This disclosure shows how the above idea is resolved.

Transparent plastic templates ruled in squares (like a cross-section paper)
are used for these purposes. However the ruled lines on them are not accurate
enough because the main purpose of them is not to measure precisely. If there
are many cross-sectional lines, in addition, it is difficult to identify each
line.

It is possible to get two-dimensional coordinates at once by using drafting
machines, but they are so expensive and are not portable.

The two-dimensional ruler is aiming for easing restrictions of plastic
templates. Every ruled line is, therefore, accurate enough and easily
viewable.

Conventional transparent plastic rulers have one-dimensional ruled lines. We
expand them to two-dimensional ruled lines like a cross-sectional paper.
Different colors are used to identify each line. For example, every 1cm lines
are in red, every 5mm ones in blue, and every 1mm lines are in brown. Full
lines, dotted lines, chain double-dashed lines, and so on, are also used for
this purposes.

By placing the original point of the two-dimensional ruler [(0,0) point] onto
top-left corner of a form, we can easily get t...
