Description
【発明の詳細な説明】
「産業上の利用分野」
本発明は、掛算、割算の計算に供する計算テーブルに関
する。DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a calculation table used for multiplication and division calculations.
「従来の技術と発明が解決しようとする課題」現在、掛
算、割算はほとんどが電卓により行なわれている。これ
による場合キーを押すだけの操作により計算がなされて
いるので、研鑚の原理に関心を引くことがない。``Prior art and problems to be solved by the invention'' Currently, most multiplication and division operations are performed using calculators. In this case, calculations are performed by simply pressing a key, so there is no concern about the principle of study.
又従来の計算尺の場合は対数目盛を使用しているので計
算原理が難解であり、使用も専門的な場合に限られてい
た。Furthermore, since conventional slide rules use a logarithmic scale, the calculation principle is difficult to understand, and their use is limited to specialized cases.
本発明は斯る問題点を解決しようとするものである。The present invention attempts to solve such problems.
「問題を解決するための手段」
本発明は、上記目的達成のため、平面板に縦横各々複数
の平行線を引き原点より順次に目盛を付ける。"Means for Solving the Problem" In order to achieve the above-mentioned object, the present invention draws a plurality of parallel lines vertically and horizontally on a plane plate and marks them sequentially from the origin.
また、この原点と各平行線を差交する複数の比例線を配
して成る。Furthermore, a plurality of proportional lines are arranged to intersect this origin and each parallel line.
「作用」
如上の構成であるから、たとえば、掛算の場合、横線と
これに差交する比例線との交点の横線上の目盛が、当該
横線の位置が対応する縦方向の目盛と、比例線の目盛を
かけた積となる。``Action'' Because of the above configuration, for example, in the case of multiplication, the scale on the horizontal line at the intersection of the horizontal line and the proportional line that intersects with the horizontal scale is the same as the vertical scale corresponding to the position of the horizontal line, and the proportional line. It is the product of the scale.
割算の場合は逆に、縦線とこれに差交する比例線との交
点の縦線上の目盛が、当該縦線の位置が対応する横方向
の目盛を比例線の目盛で割った商となる。In the case of division, conversely, the scale on the vertical line at the intersection of the vertical line and the proportional line that intersects it is the quotient of the horizontal scale divided by the scale of the proportional line, which corresponds to the position of the vertical line. Become.
つまり、縦線、横線又これに差交する線とを目で見るだ
けで直ちに算定することができる。In other words, calculations can be made immediately by simply looking at vertical lines, horizontal lines, and lines that intersect with these lines.
「実施例」
図面は、本発明の実施例を示している。図において、A
は平面板を表し、Bは該平面板に表した図表である。Embodiments The drawings show embodiments of the invention. In the figure, A
represents a flat plate, and B is a diagram expressed on the flat plate.
図表Bは、縦軸、横軸共複数の平行線を各々等間隔に配
し、目盛を付し、該目盛に対応させて各平行線と差交す
る比冷戦Bcを配して成る。Diagram B is composed of a plurality of parallel lines arranged at equal intervals on both the vertical and horizontal axes, each marked with a scale, and a Philippine Cold War Bc intersecting each parallel line corresponding to the scale.
目盛は目的に応じ細かく設ければよく、又目盛の範囲も
目的に王子必要な範囲とすればよい。The scale may be set finely according to the purpose, and the range of the scale may be set as necessary for the purpose.
又横線もしくは縦線に平行に、各目盛に対応した目盛(
必要に応じ細かく設けてよい)を持った定規状のものを
スライド式カーソル(fa)として装備すれば読み取り
がより一層容易となる。又これは平行に当てることによ
りおこなうこともできる。Also, parallel to the horizontal or vertical line, there is a scale corresponding to each scale (
Reading can be made even easier if a ruler-shaped object with a sliding cursor (fa) with finely divided cursors (which may be set finely as necessary) is provided as a sliding cursor (fa). This can also be done by applying them in parallel.
なおこの平面板は柔軟性を有するものであってもよい。Note that this flat plate may be flexible.
「発明の効果」
本発明によれば、掛算、割算において、その求める答え
はその対応する線にそって読み取るだけで見出すことが
出来る。"Effects of the Invention" According to the present invention, in multiplication and division, the desired answer can be found simply by reading along the corresponding line.
特に九九算等を学習する場合には掛算の原理(掛算はあ
る数の足す回数により決る)を容易に理解できるため教
材としても利用することができる。In particular, when learning multiplication tables, etc., the principle of multiplication (multiplication is determined by the number of times a certain number is added) can be easily understood, so it can be used as a teaching material.

Claims (1)
いて、この平行線の交点の一つを原点(0点)とする。 これを基準に縦横各々目盛を付す。 また任意の横線上において交点が等間隔となるよう原点
より、各平行線と差交する複数の比例線を配して成るこ
とを特徴とする計算セーブル。[Scope of Claims] A plurality of perpendicular parallel lines are drawn at equal intervals in the vertical and horizontal directions on a flat plate, and one of the intersections of these parallel lines is defined as the origin (0 point). Based on this, scales are attached vertically and horizontally. Further, the calculation sable is characterized in that a plurality of proportional lines are arranged from the origin and intersect with each parallel line so that the intersection points are equally spaced on any horizontal line.
