[Structure] A dial used for meters such as speedometers and tachometers, in which a three-dimensional character 2 is formed on one surface of a cloth plate, the three-dimensional character 2 is formed by an expansive ink. ing.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dial used for meters such as speedometers and tachometers, and to a dial having three-dimensional characters.

[0002]

[Prior Art]

 Conventionally, dial plates with this kind of three-dimensional characters have been formed by integrally molding the cloth and vertical characters using an injection molding machine, those in which three-dimensional characters have been formed on the metal plate surface using a press, and electrostatic It is known that letters are three-dimensionally embossed by flocking. With respect to the dial plates of and, the same character is printed on the three-dimensional character according to the top surface shape of the three-dimensional character.

[0003]

[Problems to be solved by the device]

 However, in the dials of the above-mentioned 1 and 2, it is difficult to combine the three-dimensional character and the printed character, and thus it is difficult to manufacture a high-quality dial. Further, in the above dial plate, since there is a step of punching out a three-dimensional character by a press, there is a problem that the cost becomes higher than that in the case of integrally molding with an injection molding machine. Further, in the above dial plate, since the characters are raised by electrostatic flocking, there is a problem that the cost becomes higher.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a dial plate capable of easily forming high-quality three-dimensional characters at low cost.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention relates to a dial used for meters such as speedometers and tachometers, in which a three-dimensional character is formed on a cloth plate surface, It is characterized in that it is formed of an expansive ink.

[0006]

[Action]

 In the dial plate constructed as described above, characters are printed on the surface of the cloth plate with the expansive ink. Printing is performed by a normal printing technique such as screen printing. After printing, the ink is expanded by heating, adding water or the like. This completes the dial having three-dimensional characters.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. In FIGS. 1 and 2, reference numeral 1 denotes a cloth plate forming a character surface of a meter such as a speedometer and a tachometer, and a solid character 2 is formed on the surface of the cloth plate 1. The base plate 1 is a flat plate made of polycarbonate resin, acrylic resin, iron, aluminum, or the like.

The three-dimensional character 2 is three-dimensionally formed of expansive ink. This expansive ink is obtained by dispersing a pigment or dye of a predetermined color in an expansive resin and mixing a color-developing material. There are two types of expandable resins, a heat-foaming type and a water-absorption type.

The heat-foaming type resin is used, for example, as wallpaper, clothing, art printing, miscellaneous goods, and other industrial materials. In the case of New Die Foam (trade name) (manufactured by Dainichi Seika Kogyo Co., Ltd.), 120 to 130 after printing. When heated to ℃, it foams and forms a thick layer with elasticity. Also, the water-swellable resin is used, for example, as a sealing agent for water leakage prevention and anti-condensation agent. In the case of the product name Die Swell (manufactured by Dainichiseika Kogyo Co., Ltd.), it can be used up to 300 times by contacting it with water after printing. It absorbs a certain amount of water and swells and retains water.

In the dial plate configured as described above, as shown in FIG. 3, the letter A is printed on the cloth plate 1 with the expandable resin. This printing is performed by a commonly known printing technique such as silk screen printing. After printing, heating is performed when printing is performed with a heat-foaming type resin, and contact is made with water when printing is performed with a water-absorption type resin. As a result, the three-dimensional character 2 is formed on the surface of the cloth plate 1.

According to the dial plate configured as described above, a three-dimensional character can be formed simply by printing the expansive resin on the cloth plate 1 and heating or contacting with water, so that the dial plate is easily manufactured. It is possible to reduce the cost. Moreover, since the printed characters expand as they are and become three-dimensional, a clear three-dimensional character that is the same as the printed characters emerges. That is, it is possible to form a high-quality three-dimensional character.

[0012]

[Effect of the device]

 According to this invention, it is possible to form a three-dimensional character by printing a character with the expansive ink on the surface of the cloth plate and heating or heating the character, so that it is possible to manufacture very easily and at a low cost. Can be reduced. Moreover, since the printed characters expand and become three-dimensional, it is possible to obtain a very high-quality three-dimensional character just like the printed characters.
