Abstract

PROBLEM TO BE SOLVED: To make the installation place of braille easily identifiable by projectingly providing a main body made of a transparent resin material, such as polymethyl methacrylate dispersed with fluorescent dyestuff, polycarbonate or polystyrene, etc., under specific restriction conditions with desired braille. SOLUTION: The main body 3 having inclined rim surfaces 5 consisting of a thin sheet made of polymethyl methacrylate dispersed with the fluorescent dyestuff 1 of an orange system are projectingly provided with the desired braille 4. A pressure sensitive adhesive 6 is applied on the rear surface of the main body 3 and release paper 7 is peelably deposited on the coated surface. The main body 3 converts the wavelength of the rays entering from an incoming light part by the fluorescent dyestuff 1 to change the light to fluorescence and retroreflects the greater part of the fluorescence to the rim surfaces 5 and the projecting surfaces in compliance with the rule of total reflection to glow these surfaces so as to highlight the surface with strong luminous intensity, thereby intensifying the expressing force to the outside. Namely, the device glows well over the entire part to offer appealing to blind persons (persons capable of reacting with light or partial color blind persons).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin insertion slot of a public telephone, an insertion slot / exit of a card, or a coin slot of an automatic vending machine or an automatic ticket vending machine, or an insertion slot / exit of a card. The present invention relates to a braille device which is attached to inform or guide the presence of the mouth or to inform the amount of money, or is attached to a required place for route guidance or other guidance / explanation.

[0002]

2. Description of the Related Art A braille device of this type known in the prior art is
Since the braille was formed on an aluminum plate or a stainless plate, there was a problem that it was difficult for the blind to know where it was attached.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a new braille device which can solve the above problems.

[0004]

In order to achieve the above object, a braille device according to the present invention comprises a transparent resin 2 material such as polymethylmethacrylate, polycarbonate in which a fluorescent dye 1 is dispersed, or polystyrene under specific constraint conditions. Main product 3
It is characterized in that a desired Braille 4 is provided in a convex shape.

[0005]

In the present invention, the main body 3 wavelength-converts the light rays entering from the light-incident portion into fluorescent light by using a fluorescent dye, and most of the fluorescent light is retroreflected to the edge or convex surface according to the law of total reflection. It shines these surfaces prominently with a high luminous intensity, thus strengthening the power of showing to the outside. That is, the Braille device according to the present invention shines well as a whole to appeal its presence to blind people (people who can react to light and people with color blindness).

[0006]

According to the Braille device according to the present invention, since the place where the Braille device is attached looks shining, it is easy for a blind person to recognize its existence and it is convenient to use it without any confusion.

EXAMPLE The example shown in the figure is an orange-based fluorescent dye 1.
A desired braille 4 is provided on a main body 3 having an inclined edge surface 5 made of a thin plate made of polymethylmethaacrylate resin in which
A pressure sensitive adhesive 6 is applied to the back surface of the main body 3 and a release paper 7 is releasably attached to the applied surface. For example, as shown in FIG.
It is intended to be attached and used near the entrance 9.

The present invention is directed to a special fluorescent dye [Fluoresce-nce Orange 240, Re
d 300, Yellow 083, VLHighly Pure (Violet 570), Red
339, Violet 654] is mainly used as the fluorescent dye 1, and a polycarbonate or a transparent resin such as polystyrene under specific constraint conditions may be used instead of the polymethylmethacrylate resin. The same color as the fluorescent dye 1 or a bright color, and the main body 3
A hard or soft material can be used as the material for the main body 3, and the main body 3 can be attached by screwing, embedding, or another method, and the main body 3 can be further illuminated to improve visibility. In addition, a retroreflective layer can be provided on the back surface thereof.
