Abstract

PURPOSE:To obtain a handy guide for an overseas travel, by combining pierced circles, triangles, squares, pentagons, hexagons and stars, a protractor, conversion table of weights and measures, rapid-calculating conversion table of metric system and currency table of world's principal countries. CONSTITUTION:In face of overwhelming popularity of cards of late, a ruler is added to pen, note-book as portable stationaries for outdoor use. As sometimes a man encounters a chance in which he misses a scale for measurement or a protractor depending upon his occupation and hobby, he decides to carry with him not only a credit card in his purse which he carries always, but as to a card-formed ruler combined with the protractor, etc. When he carries these things at all, and takes the remotest possible chance into consideration, he also carries a conversion table of weights and measures, table of rapid calculation, table of currencies of the world's principal countries for additional equipment to his overseas travel. By this, a handy guide for his overseas travel becomes available.

Description

[Detailed Description of the Invention] This invention has made it more familiar to add a ruler to stationery, pens, and notebooks when going out, in line with the modern age of cards.

There are probably many people, not just adults but also children, who have happened upon a scale to measure dimensions when they go out.

Furthermore, there are probably many people who have come across a protractor by chance, depending on their occupation or hobby.

Therefore, we thought of carrying not only a credit card but also a card-shaped ruler with a protractor, etc., in the wallet that everyone carries at all times.

Therefore, if we are to display the same information, we will take into account the greatest possible chance and include weights and measures conversion tables, speed calculation tables, and currency tables of the world's major countries for when traveling abroad.

Other people probably don't go out without bringing a thermometer with them, but as fever comes on suddenly, you can use the thermometer as a guideline to treat sudden headaches until you go home or go to work. It is a good idea to add a thermometer with a color display as a guide.

By adding scales called rulers and protractors to children's play, even when they are out and about without stationery, children who are interested in numbers can enrich and develop their exploration skills. You will be satisfied with the coincidence that can happen.

Cutting out circles and other shapes is used to describe simple shapes beautifully, but by combining them, children develop their creativity to create many designs and figures.

Additionally, if you have a weights and measures conversion table, quick conversion method, and world currency table, you will have a simple guide when traveling abroad.

A magnifying lens is useful when reading maps, etc.
