2. Description of the Related Art In the United States and other countries, it is obliged to install Braille marking plates in buildings so that visually handicapped persons can safely and safely live as members of society. However, in Japan, these social welfare aspects are still insufficient, and in the future, Braille marking boards will be widely used in hospitals and various other facilities so that visually impaired persons can live safely and securely as a member of society. It is desired to be installed. For that purpose, it is necessary to provide braille marking boards of excellent quality at low cost.

The method of manufacturing the Braille marking plate is as follows.
A knife coater is provided with a photo-curable resin having a predetermined thickness (for example, 0.3 mm) on a substrate or an adhesive layer applied on the substrate.
After coating with a brush or other method, the photocurable resin is exposed to ultraviolet rays by irradiating it with ultraviolet rays through a production manuscript above the photocurable resin layer, that is, an original film, and then the unexposed portion is exposed to a solvent and / or water. After washing with a developing solution consisting of 1 and drying, a prototype of a Braille marking plate having Braille with square corners is obtained. Liquid UV using a spoid or the like with an extremely fine tip diameter on the braille vertex of the original braille marking plate
Pour the ink. The tip diameter of the spoid is the Braille width or UV
It is appropriately determined depending on the viscosity of the ink. As shown in FIGS. 1 (c) and 2, the ink rides on the Braille apex with its tip being rounded by the surface tension. Immediately in this state, the ink is photocured by irradiating ultraviolet rays from above the prototype marking plate using a UV lamp, and the Braille marking plate of the present invention can be manufactured. The obtained Braille marking plate is optionally coated with a resin liquid or other protective film.

In the present invention, as a method for rounding the braille vertices, liquid UV ink is poured onto the braille vertices of a prototype marking plate having angular braille vertices, and then while the ink is curled due to surface tension. A method of rapidly irradiating the entire surface of the sign board or a necessary part with ultraviolet rays to photocur the ink in a curled state was adopted. Therefore, the manufacturing method of the invention of the present application is extremely short and inexpensive in both the manufacturing of the original film and the rounding of the braille vertices, as compared with the conventional method of machining the braille vertices of the male die master with a file. The braille can be manufactured in high accuracy and the accuracy of each braille obtained is high, and since it is also rounded, it can be used as a formal braille in public facilities.
