Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming Braille, etc., and includes, for example,
This paper relates to Braille, various figures, and the expansion molding of Braille and various figures onto paper.

Conventionally, when forming Braille, for example, the original Braille shapes were individually extruded onto metal master discs by hand, the master discs were placed one above the other, and paper was sandwiched between the master discs. The upper and lower master discs are pressed against each other through a sheet of paper, and the original shape of the master disc is extruded onto the paper. However, with this method, the original shape of the Braille is individually extruded by hand, so it takes a lot of work to make the master, and since the Braille is formed by hand, the Braille paper itself It takes a lot of time and effort to manufacture, and as a result, there are problems such as poor productivity and increased costs.

Therefore, recently, a perforator is used to perforate the original shape of Braille on a sheet, and this sheet is then run through a printing machine to print ink with a foaming agent on the sheet, and this is then dried in a dryer. A method has been adopted in which the sheet is placed in a foaming machine to foam the foaming agent in the sheet to form predetermined Braille characters. However, according to this method, the formation of Braille is performed using different devices that perform individual tasks, which not only involves many steps, but also involves a large number of steps.
It requires troublesome means to proceed to the next step, and the finished product is slow.Therefore, in this case as well, there are problems such as poor productivity and increased costs.

The present invention was made in view of these points,
To provide a method for forming Braille, etc., which can be easily formed on paper by swelling, and which can be finished quickly.

Next, one embodiment of the present invention will be described based on the accompanying drawings.

1 is a paper made of paper or synthetic resin film, and on one side of this paper 1, that is, on the surface,
The film 2 is formed by applying a solvent that easily absorbs infrared rays and containing a foaming agent by means such as painting.

As the synthetic resin film as the paper 1, for example, various synthetic resin films such as vinyl chloride or polypropylene with a predetermined thickness can be used, and almost any white paper can be used. It is also possible to use anything.

The foaming agent used is, for example, Micropearl F-30, the solvent, for example, Marposol RD502, and the dye, for example, Emacol Red BS. Consists of Micropearl F-30 15g Solvent: Marposol RD502 10g Dye: Emacol Red BS 0.5g.

Next, on the film 2 side of the paper 1 having the film 2 on its surface, a pattern paper 4 made of paper with perforated patterns 3 such as Braille or a negative film with the portions of the Braille etc. outlined in white is placed. Polymerize.

As the film, for example, a photosensitive film (manufactured by 3M) is used. Further, as the paper, a thick plate having a predetermined thickness is used. Then, as the original form 3 of the original form paper 4, predetermined Braille characters are perforated using a typewriter such as a Braille perforation typewriter, for example.

Next, as shown in FIG.
With the above-mentioned material 1 superposed on top, this is placed and fixed on the upper surface of the opening of the light emitting device 5. The light emitting device 5 is
It has a box-shaped main body 6 with an open top surface, and a locking ridge 7 that locks around a transparent heat-resistant glass plate or acrylic resin liquid 16 is formed inside the main body 6. is provided with a reflecting mirror body 8 formed in the shape of an inverted cone, the opening upper edge 9 of this reflecting mirror body 8 is connected to the above-mentioned locking protrusion 7, and the center part of the bottom part 10 of the above-mentioned reflecting mirror body 8 A light emitter 11 such as a xenon lamp that emits light including infrared rays is fixed to.

Next, after placing the original paper 4 having the paper 1 on top on the light emitting device 5, the light emitting body 11
When the is energized to emit light, the light including infrared rays passes through the perforated original form 3 of the original form paper 4 directly or via the reflecting mirror 11, and the film of the paper 1 corresponding to this original form 3 is transmitted. The foaming agent in the film 2 of the irradiated region foams, so that it is instantly bulged to a predetermined height according to the shape of the original shape 3.

Next, the original paper 4 on which the paper 1 has been polymerized is taken out from the light emitting device 5, and the paper 1 is separated from the original paper 4, thereby obtaining the paper 1 on which predetermined Braille characters 12, etc. are integrally formed by swelling on the surface. Can be done.

Next, in the above embodiment, there are 12 Braille characters on the paper 1.
Although the case of swelling molding has been described, the present invention is not limited to this; the original form 3 perforated on the original form paper 4 may be, for example, perforated or photographed in the form of various figures, or Braille and figures may be combined, for example, It is constructed by combining the Braille original form 3 corresponding to the mountain character and the mountain figure original form 3, and is polymerized on the film side of the solvent containing a foaming agent as in the above example, and By irradiating light beams on the surface, a display of a predetermined figure or a combination of a predetermined figure and Braille can be easily formed into a bulging form, and paper with this combination etc. can be obtained. It becomes possible to teach in a related manner. In the embodiment, the case where a perforated original paper and a negative film were used were explained, but as shown in FIG. A film 15 whose transparent portion 14 is exposed by writing may be used, and by polymerizing the handwritten film and the paper 1 and irradiating it with light, it can be instantly bulged.

According to the present invention, original paper made of paper or synthetic resin coil having a desired original shape such as Braille is applied to a film containing a foaming agent formed on the surface of paper made of paper or synthetic resin film. By irradiating the paper with infrared rays from the side of the original paper, the rays will surely irradiate the film in the corresponding areas through the original paper, and the foaming agent in the areas irradiated with the rays will also be irradiated. It is possible to foam and instantaneously form bulging Braille characters that conform to the original shape on the paper, and it is also instantaneously finished, making it possible to easily create paper with bulged Braille characters, various figures, or a combination of Braille and figures. Moreover, since it is obtained by polymerizing paper and original paper and irradiating it with light, the process is extremely small and it is easy to move on to the next process. The procedure does not require complicated operations, and therefore, the overall mass productivity is excellent, productivity can be greatly improved, and costs can be significantly reduced. Furthermore, it has the great advantage of being able to be formed instantly, so when used in combination with a handwritten film, it has the great advantage of being able to immediately embody and present the shape of an object even during a conversation with a blind person.
