た。However, in the above, the vertical direction cannot be discriminated only by looking at the outer shape, and it is necessary to read a small number for the vertical discrimination, and the two base lines for measuring the height of the DUT are in the longitudinal direction. Since it is drawn at intervals and the scale for displaying the distance is drawn in the horizontal direction, it requires more than a certain size in both the vertical and horizontal directions, and it is bulky. When measuring even short distances, it is inconvenient to carry because it becomes larger. In addition, the transparent plate must be moved in both vertical and horizontal directions to match the DUT to the baseline, especially when the DUT is moving away or approaching, it is difficult to align with the baseline, which makes distance measurement very difficult. It was good.

実施例 以下、本発明の実施例を図面に基いて詳細に説明する
と、第１図に示すように、距離測定用ものさし１は塩化
ビニル，ガラス，ハイプラスチック等を素材とする頭
部，胴部及び足部よりなる人体の輪郭をした透明板２よ
り成る。透明板２は、標準的な人間の身長である160cm
の1/10すなわち16cm程度の高さと、2.5〜3cmの幅を有す
る。EXAMPLE An example of the present invention will be described in detail below with reference to the drawings. As shown in FIG. 1, a distance measuring ruler 1 is a head and a body made of vinyl chloride, glass, high plastic or the like. And a transparent plate 2 having the contours of the human body including the legs. The transparent plate 2 has a standard human height of 160 cm.
It has a height of about 1/10 or 16 cm and a width of 2.5 to 3 cm.
透明板２には長手方向に沿って目盛３が描かれている。
この目盛３の原理について説明すると、頭部頂点を基点

物４までの距離をD,計測者５と距離測定用ものさし１と
の間隔をd,透明板２位置での被測定物４のみかけ上の高
さすなわち、基点からの長さをｈとすると、第４図に示
すように、H:h＝D:dの関係が成り立ち、ここからｈ＝Ｈ
・d/Dの式が導かれる。A scale 3 is drawn on the transparent plate 2 along the longitudinal direction.
Explaining the principle of the scale 3, the actual height of the DUT 4 is H, the distance from the measurer 5 to the DUT 4 is D, the measurer 5 and the distance measuring scale are based on the vertex of the head. 1 is d, and the apparent height of the DUT 4 at the position of the transparent plate 2, that is, the length from the base point is h, as shown in FIG. 4, H: h = D: d Is established, and from here h = H
・ The formula of d / D is derived.
従って、Ｈ及びｄの値を定め、Ｄの数値を様々に変化さ
せて上記式ｈの値を求め、透明板２の頭部の基点７から
の長さがｈの値と一致するように目盛３を描き、これに
対応する距離Ｄを表示しておけば、上記定められた条件
どおりの被測定物４を計測者５の眼前から定められた間
隔ｄをあけて立設された透明板２を透して視た時、被測
定者４のみかけ上の高さｈと一致する目盛３を読みとれ
ば、距離Ｄがわかることになる。Therefore, the values of H and d are set, the value of D is variously changed to obtain the value of the above expression h, and the scale is set so that the length of the head of the transparent plate 2 from the base point 7 matches the value of h. 3 is drawn and the corresponding distance D is displayed, and the object to be measured 4 according to the above-specified conditions is erected at a predetermined distance d from the front of the measurer 5 and the transparent plate 2 is erected. When seeing through, the distance D will be known by reading the scale 3 that matches the apparent height h of the person to be measured 4.
本実施例においては、透明板２に例えばＨを160cm、ｄ
を50cmと定めた時の目盛３及びこれに対応する距離表示
６が描かれている。In this embodiment, for example, H is 160 cm, d
A scale 3 and a distance display 6 corresponding to the scale 3 when 50 cm is set are drawn.
次に、距離測定用ものさし１の使用方法を説明する。Next, a method of using the distance measuring ruler 1 will be described.
計測者５は眼前50cmの間隔をあけて距離計測用ものさし
１を立て、透明板２を透して適宜距離に位置する高さ16
0cmの被測定物４例えば身長160cmの人間を視る。そし
て、距離測定用ものさし１を上下に動かして被測定物４
の上端を透明板２の基点７に合わせ、下端の目盛３を読
みとる。すると、該目盛３の距離表示６によって直ちに
被測定物４までの距離が計測できる。The measurer 5 stands the distance measuring ruler 1 at an interval of 50 cm in front of the eye, passes through the transparent plate 2, and is positioned at an appropriate distance 16
An object to be measured 4 of 0 cm, for example, a person with a height of 160 cm is viewed. Then, move the distance measuring ruler 1 up and down to move the measured object 4
Align the upper end with the base point 7 of the transparent plate 2, and read the scale 3 at the lower end. Then, the distance display 6 on the scale 3 can immediately measure the distance to the DUT 4.
一例をあげると、透明板２の高さは160cmなので、上記
のように条件を設定した場合には、第２図に示すよう
に、被測定物４と透明板２とが等身となった時は被測定
物４が計測者５から5mの距離に位置することになり、第
３図に示すように、被測定物４がＡ点に位置し、透明板
２の高さの1/2に見える時は被測定物４と計測者５との
距離が10mであり、被測定物４がＢ点に位置する時は、
その高さと一致する目盛７の距離表示６によってＢ点ま
での距離が7mであることがわかる。As an example, since the height of the transparent plate 2 is 160 cm, when the conditions are set as described above, when the DUT 4 and the transparent plate 2 become life-size as shown in FIG. Means that the DUT 4 is located at a distance of 5 m from the measurer 5, and as shown in FIG. 3, the DUT 4 is located at the point A and is half the height of the transparent plate 2. When it is visible, the distance between the DUT 4 and the measurer 5 is 10 m, and when the DUT 4 is located at the point B,
It can be seen from the distance display 6 on the scale 7 that coincides with the height that the distance to the point B is 7 m.
なお、透明板２の高さは必ずしも16cmではなく、学童を
被測定物４の対象とする時はこれより小型とすることも
できる。It should be noted that the height of the transparent plate 2 is not necessarily 16 cm, and when a school child is the target of the DUT 4, it can be made smaller.

として最適である。EFFECTS OF THE INVENTION According to the distance measuring ruler of the present invention, the vertical position of the transparent plate can be reliably and easily set only by turning the head, which is a normal human figure, upward, and the transparent plate can be transparently measured. Look at things,
You can easily measure the distance from the measurement point to the object to be measured by simply reading the distance display on the transparent plate so that it matches the scale on the transparent plate. Since the width of the transparent plate is narrow, it is compact and convenient to carry for short-distance measurement, and the distance measuring ruler is moved vertically to cover the base point of the head. Since it aligns with the upper end of the object to be measured, it can be aligned accurately.After that, the object to be measured is aligned with the scale, so even if the object to be measured goes away or approaches, it is easy to match the scale, especially the distance. It is most suitable as a learning material for measuring methods.
