(57) [Summary] (Correction) [Construction] This is a concave reflecting mirror in which the convex lens side 2 of the Fresnel lens 1 for a convex lens is mirror-finished so that the opposite side 4 can be used as a concave mirror. [Effect] By using the Fresnel lens, the mirror surface can be made flat, which was impossible with the conventional concave mirror, and the same effect as the conventional concave mirror can be obtained. Furthermore, by using various new materials such as acrylic and polycarbonate, it is possible to obtain a product that is extremely thin and extremely lightweight, and that is several tens and several hundred times stronger than conventional products.
Description
【考案の詳細な説明】 この考案は化粧の時に用いる鏡に、凹面鏡を用いて、化粧の細部を拡大して容易 に、且っ明瞭に見える様にした化粧用の鏡に関するものである特に眼鏡着用を必 要とする人にとっては、眼の部分の化粧には眼鏡の使用が邪魔となり、眼鏡を外 すと視度が低下して明瞭に見ることが出来ないという欠点がある。凹面反射鏡を 用いれば眼鏡の着用なしでも明瞭に細部まで拡大して見えるので、極めて容易に 化粧が出来る。[Detailed Description of the Invention] The present invention relates to a makeup mirror in which a concave mirror is used as a mirror used during makeup so that the details of the makeup can be magnified easily and clearly. For those who need to wear it, the use of spectacles is a hindrance to the makeup of the eyes, and when the spectacles are removed, the diopter is reduced and it is not possible to see clearly. Even if you don't wear eyeglasses, you can see the details clearly and clearly using a concave reflector, so you can apply makeup very easily.
この目的による従来の凹面反射鏡は、単レンズ式の凹面鏡であった為、凹面鏡中 心部の膨らみによる厚みが大きく、また一般にガラス製であったため凹面鏡の強 度保持の為に厚みが必要となり、そのための重量が増え、携帯にも不便、製作、 加工にもコストが大きく、破損しやすいという欠陥があった。本考案は、従来の 反射鏡の欠陥である厚さと重量と製作、加工コストの関係改善のために、フレネ ルレンズの凸レンズを用いこれの凸レンズ面に鏡面メッキを施したものである。Since the conventional concave reflecting mirror for this purpose is a single-lens type concave mirror, it has a large thickness due to the bulge of the central part of the concave mirror, and since it is generally made of glass, a thickness is necessary to maintain the strength of the concave mirror. As a result, the weight is increased, it is inconvenient to carry, the cost is high for manufacturing and processing, and it is easily damaged. In the present invention, in order to improve the relationship between the thickness and weight, which are defects of the conventional reflecting mirror, and the manufacturing and processing costs, a convex lens of the Fresnel lens is used and the convex lens surface of this lens is plated with a mirror surface.
これにより、フレネルレンズの効果で、鏡面を平坦にすることが出来る。更にア クリル、ビニール、ポリカーボネート等の樹脂材を用いれば、その厚みを極端に 薄くすることが可能となり、重量も極めて軽減させることが出来、且つ極めて破 損しにくいものが容易に得られる。Thereby, the mirror surface can be made flat by the effect of the Fresnel lens. Furthermore, if a resin material such as acrylic, vinyl, or polycarbonate is used, the thickness thereof can be made extremely thin, the weight can be extremely reduced, and a material that is extremely resistant to damage can be easily obtained.
