【発明の詳細な説明】
［産業上の利用分野］
本発明は、各種エレクトロニクス機器等に使用
される接点ゴムのうち照光式のものの製造方法に
関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for producing light-emitting rubber contacts used in various electronic devices.
［従来の技術］
従来のキートツプ一体形の照光式接点ゴムは、
キートツプの文字面のみを透明材と着色材とで２
色成形するもののみで、側面を遮光したものは存
しない。[Conventional technology] Conventional key top integrated illuminated rubber contacts are
Only the character surface of the key top is made of transparent material and colored material.
Only those with color molding are available, and there are no types with light-shielding sides.
［考案が解決しようとする問題点］
キートツプ一体形の接点ゴムでは、側面の遮光
が難しく、従来は遮光されていないため、接点部
全体が光つてしまい高級感を望むことができなか
つた。側面をシリコンインク等の遮光材で印刷す

は方形等の形状を機械的に印刷することは非常に
難しいものである。[Problems that the invention aims to solve] With rubber contacts that are integrated into the key top, it is difficult to block light from the sides, and since conventionally there was no light shielding, the entire contact area was shiny, making it impossible to achieve a high-class feel. Although it is possible to print the side surfaces with a light shielding material such as silicone ink, it is extremely difficult to mechanically print shapes such as cylinders, domes, or rectangles.
［問題点を解決するための手段］
そこで本発明においては、側面を遮光インクで
印刷する難しい方法をとらずに、あらかじめキー
トツプの側面形状に合わせた遮光部を空胴に成形
しておき、成形時に先に金型内にインサートして

うようにしたものである。[Means for solving the problem] Therefore, in the present invention, instead of using the difficult method of printing the side surfaces with light-shielding ink, a light-shielding part that matches the shape of the side surface of the key top is formed in advance in the cavity, and the molding In some cases, it is first inserted into a mold and then molded integrally with the contact rubber body.
［実施例］
次に図面に示す実施例に従つて本発明を説明す

を抜いた印刷を行ない照光式接点ゴムを製作す
る。 A hollow light shielding part 1 made by molding a light shielding material such as colored silicone rubber in advance according to the side shape of the key top is inserted into the key top molding part of the mold 2, and then silicone, which is the material of the contact rubber body, is inserted into the mold 2. Put the rubber fabric 3, close the mold, and remove the side light shielding part 1.
integrally molded with Characters, etc. that you want to shine on the key top surface with silicone ink 5 after molding 7
Printing is done to produce illuminated contact rubber.
そして、この照光式接点ゴムは第２図に示すよ

る。 This illuminated contact rubber is used as shown in FIG. In the space 6 in the contact rubber 10, an LED 9 for illumination is placed upright from the lower substrate 4.
This light is blocked by the side light shielding part 1 and the light shielding printing part 5 on the key top surface, and only the portion 7 of the key top surface such as characters is transmitted and illuminated. 8 is a housing.
第３図は、成品例を示すものである。 FIG. 3 shows an example of the finished product.
［考案の効果］
