【考案の詳細な説明】
本考案は親水性プラスチックスで作ったソフトコンタク
トレンズの外径を測定するスケールルーベに関るもので
ある。[Detailed Description of the Invention] The present invention relates to a scale Roubaix for measuring the outer diameter of soft contact lenses made of hydrophilic plastics.
従来のこの種のスケールルーベでは、ソフトコンタクト
レンズが空気中にあるため、測定中に水分の蒸発で含水
量が減少し、外径が小さくなるし、ソフトコンタクトレ
ンズが軟いため、その縁をスケールの零点に合わせると
き、変形させることが多い。In the conventional scale Roubaix of this kind, since the soft contact lens is in the air, the water content decreases due to evaporation of water during measurement, and the outer diameter becomes smaller. When adjusting to the zero point of , it is often deformed.
本考案はこれらの欠点を除去するため、スケール板の前
面にソフトコンタクトレンズ挿入用の液槽を設けたもの
である。In order to eliminate these drawbacks, the present invention provides a liquid tank for inserting soft contact lenses on the front surface of the scale plate.
次に図示の実施例につき詳細を説明する。The illustrated embodiment will now be described in detail.
第１〜２図において、１は基板を示し、その一端上にソ

して、その内面にスケール５を表示する。In FIGS. 1 and 2, 1 indicates a substrate, on one end of which a vertically flat rectangular liquid tank 3 made of glass into which a soft contact lens 2 is to be inserted is fixed, and its back plate 4 is used as a scale plate. Scale 5 is displayed on its inner surface.
そしてこのスケール板に焦点を結ぶべき拡大レンズ６を
基板１の他端に枠片７で固定し、さらに液槽３内にスケ
ールの零点基準の底部８を設ける。A magnifying lens 6 to focus on this scale plate is fixed to the other end of the substrate 1 with a frame piece 7, and a bottom part 8 is provided in the liquid tank 3 as a reference for the zero point of the scale.
本考案のルーペはこのような構造のもので、液槽３内に

の外径を知ることができる。The loupe of the present invention has such a structure. After filling the liquid tank 3 with, for example, water 9, inserting the soft contact lens 2 whose outer diameter is to be measured, the periphery of the soft contact lens 2 is placed on the bottom 8 and the scale 5. To the side plate 10 of the nearby liquid tank! When the lens is pressed slightly against the scale plate 4, the lens is attracted to the scale plate by suction cup action, and through the magnifying lens 6, the value on the scale 5 (not shown) that matches the periphery of the soft contact lens can be seen. For example, the outer diameter of the soft contact lens can be immediately known.
そして本考案によれば、外径を測ろうとするソフトコン

にその外径を測定できる。According to the present invention, since the soft contact lens whose outer diameter is to be measured is placed in the liquid in the liquid tank, the soft contact lens will not shrink due to water evaporation, and even if it is soft, it can be adjusted to the zero point. Since it sticks to the scale plate with slight pressure, its outer diameter can be measured accurately without fear of deformation.
なお、この実施例では液槽３をガラス製としたが、他の

数値をスケール板４に施してもよい。Although the liquid tank 3 is made of glass in this embodiment, it may be made of any other suitable material, and the front plate 11 may be made transparent. The soft contact lens may have a curved concave surface, a square surface as shown in FIG. 4, etc., and a scale 5 and a numerical value indicating the outer diameter of the soft contact lens may be correspondingly provided on the scale plate 4.
