Description
【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、エレクトロニクス機器たとえば携帯自動車
電話、カーステレオ等のスイッチにおいて、キー面の文
字や絵部分のみが透光する照光式ラバーシートの製造方
法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to the manufacture of an illuminated rubber sheet in which only characters and pictures on a key surface of an electronic device such as a cellular phone and a car stereo are transmitted. It is about the method.
［従来の技術］ 従来の照光文字は透光性材料からなる文字等表示面
に、この文字表示面に附着しない材料にて所定の文字等

し、それ以外の不透明なエリアのみを残すような製造方
法をとっている。[Prior Art] Conventionally illuminated characters are printed on a character display surface made of a translucent material with predetermined characters or the like using a material not attached to the character display surface, and then coated with a paint to be attached to the translucent material. A manufacturing method in which a paint is applied with a spray gun or the like, and then the non-adhesive material of the character line portion printed earlier is removed, and the coating film thereon is removed by washing or the like, leaving only other opaque areas. Has taken.
［発明が解決しようとする問題点］ 従来の方法では、シリコーンゴムを使用したラバーシ
ートの場合、シリコーンゴムに附着しないインクはなじ
みが良くないため、印刷時のにじみ、カケ等が発生しや
すく、細い文字や細い線の成形が困難であった。[Problems to be Solved by the Invention] In the conventional method, in the case of a rubber sheet using silicone rubber, the ink that does not adhere to the silicone rubber does not fit well, so that bleeding at the time of printing and chipping are likely to occur. It was difficult to form thin characters and thin lines.
［問題点を解決するための手段］ 本発明は照光させたい文字部分以外の表示面に附着す

膜をとりのぞく方法をとる。[Means for Solving the Problems] In the present invention, printing is performed using an opaque material attached to the display surface other than the character portion to be illuminated, and the portion to be illuminated is formed as a blank character. Then, masking is performed with a material that does not adhere to the entire printed portion, and painting is performed. Then, a method of removing the coating film on the masking material together with the masking material is adopted.

光がない時でも字体がはっきりみえるようにするための
ものである。Example A transparent silicone rubber 1 is vulcanized and molded with a rubber mold, and a white silicone ink 2 is screen-printed solidly on the top surface of the molded silicone rubber product 1 and thermally cured at 200 ° C. The white color is the undercolor of the font of the blank character, so that the font can be seen clearly even when there is no illumination from below.
次に天面の白ベタ印刷の上に、照光させたい文字３を
黒色のシリコーインクにて抜き文字スクリーン印刷し、
200℃にて熱硬化する。その後、天面全体をシリコーン
インクに附着しないウレタンインク等の材料４を用いて
マスキングする。シリコーンゴム表面全体を黒色のシリ
コーン塗料５でスプレー塗装し、180℃〜200℃で熱硬化
する。Next, on the white solid printing on the top surface, the character 3 to be illuminated is extracted with black silicone ink and character screen printing is performed.
Thermoset at 200 ° C. Thereafter, the entire top surface is masked using a material 4 such as urethane ink which does not adhere to the silicone ink. The entire surface of the silicone rubber is spray-coated with a black silicone paint 5 and thermally cured at 180 ° C to 200 ° C.
マスキング部４とマスキング部の上の黒色塗装膜５を
水洗浄等の方法で除去する。The masking part 4 and the black coating film 5 on the masking part are removed by a method such as water washing.

字画の大きい漢字にも対応できるようになった。[Effects of the Invention] Characters to be illuminated are printed with ink attached to silicone rubber and then printed, and then the entire printed portion is masked with ink that is not attached, thereby illuminating characters and the like thinner than conventional products. It is now possible to handle the large number of kanji that have recently increased in strokes.
