（産業上の利用分野）
本考案は、道路標識やテール反射鏡等に用いて
有効な光反射標識に関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a light reflecting sign that is effective for use in road signs, tail reflectors, etc.
（従来の技術）
三つの直角三角形からなる三角錐がガラス等の

されている。(Prior Art) When a triangular pyramid consisting of three right triangles is made of a light-transmitting material such as glass, it is already known that it is a so-called retroreflector that reflects parallel light rays incident at right angles to the base toward the light source. Are known. Various types of side road signs and the like using such retroreflectors have been put into practical use.
（考案が解決しようとする問題点）
従来のこの種再帰反射体を用いた光反射標識

ものの多くはその三角錐（以下三角プリズムと云
う）の大きさが高々１個／cm2程度であり、加工上
の制約から20個／cm2を限度とするものであつた。(Problems to be solved by the invention) Conventional light reflective signs using this type of retroreflector are molded bodies made of glass or hard plastic material, and although they are not in practical use. In many cases, the size of the triangular pyramids (hereinafter referred to as triangular prisms) is about 1 piece/cm 2 at most, and the number was limited to 20 pieces/cm 2 due to processing constraints.
従つて、このような三角プリズムを面上に連続

するものであつた。 Therefore, in a reflector formed by continuously expanding such triangular prisms on a surface, due to limitations in the material and molding, the prism edges are not sharp enough, and
As a result, some gaps are created on the edges between each prism, and as a result, light absorption and diffusion occur at these edges and edges, resulting in a decrease in reflection efficiency and a pattern with stripes as a reflected image. , and had a partially glittering mosaic-like appearance.

ものである。 On the other hand, the applicant previously obtained a retroreflective film sheet in which about 1000 to 3600 micro triangular prisms/cm 2 were cut on one side of a soft sheet (thickness 0.2 mm) of acrylic resin or polycarbonate resin. The sheet can be freely shaped into shapes by cutting, has excellent weather resistance, and has water repellency due to the dense microprisms on the prism-constituting surface.In particular, as shown in the attached reflective performance tables (1) and (2), It has unparalleled reflection brightness even over a wide range of light incident angles.
そこで、本考案は、上記再帰性反射フイルムシ

きに集中する。(Function) A retroreflector made of a resin film sheet is
The light incident on the light incidence surface is reflected 360° and returned toward the light source. In this case, the reflection efficiency is more efficient as the angle of incidence is smaller, as shown in the performance tables (1) and (2) above, and moreover, the reflection efficiency is concentrated in the direction where the angle of reflection is perpendicular to the plane of incidence.
従つて、これを配置した標識体を側路標識等に
用いた場合に、走行車のヘツドライト照明により
これが恰も高輝度の光源球を設置しているかのよ
うな状態を呈する。 Therefore, when a sign with this arrangement is used as a side road sign or the like, the illumination of the headlights of a traveling vehicle makes it appear as if a high-intensity light source bulb had been installed.
高輝度の反射体は、霧発生等の気象状況におい

る。 In order to prevent this and to exhibit the uniqueness as a sign, an opaque plate with through holes arranged at intervals, a colored transparent plate and a retroreflector underneath the opaque plate function effectively. That is, by utilizing the partially transmitted light in the upper layer retroreflector and arranging the plate on the back side thereof, the previous transmitted light passes through the through hole of the plate, and the colored transparent plate below it passes through the through hole of the plate. After passing through the filter action area, the light is retroreflected by the retroreflector in the lower layer and directed toward the retroreflector in the upper layer. Since the colored light is filtered by the filter and is reflected only from the through-hole portion, the colored light from the through-hole portion that transmits it from the back side is added to the fully reflected light from the uppermost layer retroreflector. When the light is mixed, the reflected image becomes a pattern of scattered colored patterns made up of small holes. This makes the reflected image pattern different from that of normal headlight light, making it more useful as a light reflecting sign.

Approximately 80% of the light is reflected by the retroreflector 7 directly below it as shown in Figure 4, and the light that has passed through it is reflected by the perforated opaque plate 6 below it, except that it is directed toward the through hole 5. While most of the portion is absorbed, the portion that passes through the through holes 5 of the perforated opaque plate 6 is filtered by the colored transparent plate 4 and is absorbed by the retroreflector 3 in the lower layer.

Then, the colored light is emitted from the transparent lid plate 2. Therefore, the colored reflected light that passes through the uppermost layer retroreflector 7 from the back side is mixed with the light reflected on the entire surface of the reflector 7, and the reflected image becomes a colored pattern of dots made of small holes. This is the pattern that exists.

く喚起する。(Effects of the invention) As described above, the sign according to the invention uses two retroreflectors in which micro triangular prisms are densely formed on one side of a soft synthetic resin film sheet, and An opaque masking plate with through holes arranged at intervals and a colored transparent plate as a filter are interposed between the mountings. Therefore, the retroreflector has unparalleled reflection brightness even for incident light at a relatively wide angle, and moreover, the light that has passed through the upper layer retroreflector is reflected by the through-hole portion of the opaque plate. While the light is reflected by the lower layer retroreflector and reflected back, it is colored by the colored transparent plate and mixed with the light completely reflected by the upper layer retroreflector, so that the sign is dotted with colored patterns. As a result, it is possible to obtain a unique reflected image pattern, demonstrating an excellent sign function and attracting the attention of drivers.

Accordingly, the sign according to the present invention not only has excellent functionality, but also has a large degree of freedom in shape, such as the case body, that is, the sign itself, can be configured into any shape. In addition, it can be put to practical use as a wide range of light-reflecting signs such as tail reflectors and even safety badges.
