【産業上の利用分野】この発明は、裏面に金属を塗布し
ないで使える鏡に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mirror that can be used without applying metal on the back surface.

塗布する手数がかかりコストアップ要因となる。2. Description of the Related Art Conventional mirrors are made of silver on the back side of a transparent body such as glass.
It is made by coating a material with high light reflectance such as aluminum. For this reason, in addition to the number of steps for molding glass, the number of steps for coating metal or the like is required, which causes a cost increase.

【発明が解決しようとする課題】したがって、金属等を
塗布しなくて良い鏡ができればコストが大幅に安くな
る。本発明は、この要望にこたえる為になされたもので
ある。Therefore, if a mirror that does not need to be coated with metal or the like can be made, the cost will be significantly reduced. The present invention has been made to meet this need.

反射プリズムの細長いもの（図２のようなもの）を透明
板の上（鏡の裏側になる部分）に、図３のように平行に
並べたものである。勿論全反射プリズム部分と透明板部
分は一体で成型するので、図３に表示されているような
全反射プリズム部分と透明板部分の境界線は必要ない。Now, the structure thereof will be described. A transparent material having a high refractive index (preferably 1,50 or more) is used to mold it into a shape as shown in FIG. In the shape of FIG. 4, elongated elongated total reflection prisms (as shown in FIG. 2) are arranged in parallel on a transparent plate (a portion which is the back side of the mirror) as shown in FIG. Of course, since the total reflection prism portion and the transparent plate portion are integrally molded, the boundary line between the total reflection prism portion and the transparent plate portion as shown in FIG. 3 is not necessary.

の様に屈折率の高い透明体を用い裏面を鋸歯状に加工す
ることにより、銀メッキ等を施すことなく鏡を作ること
ができる。Next, the operation of the present invention will be described with reference to FIG. 6 in which the left end of FIG. 4 is enlarged.
, The front surface 3 of the mirror from the position of the incident light 6
The light incident on is totally reflected by the first total reflection surface 1 and is also totally reflected by the second total reflection surface 2 and reaches the eye 5 of the person who is looking at the mirror. By processing the back surface into a sawtooth shape using a transparent body having a high refractive index in this manner, a mirror can be formed without applying silver plating or the like.
【０００６】[0006]
【実施例】なお、第１全反射面１、第２全反射面２等の
幅は鏡を見る人から見てあまり目立たないように狭い方
が良いので全反射面の数を多くして微細構造とする。ま
た、図７の様に裏面に屈折率の低い透明体８を張り合わ
せ鏡体の強度を向上させる事もできる。EXAMPLE The widths of the first total reflection surface 1, the second total reflection surface 2, etc. are preferably narrow so that they are not noticeable to a person who looks at the mirror. The structure. Further, as shown in FIG. 7, a transparent body 8 having a low refractive index may be attached to the back surface to improve the strength of the mirror body.
