。DETAILED DESCRIPTION OF THE INVENTION (a) Field of the Invention The present invention relates to a method for manufacturing key tops used, for example, in keyboards of office automation equipment such as personal computers and word processors.
（ロ）発明の背景
従来、キートップの製造方法は、金型内にゴム材あるい
は樹脂材を射出成形して所定のキートップ形状に成形し
た後、その後処理として第５図に示すように、キートッ
プ５１の外表面上にキートップの表示記号５２をスクリ

を固着゛していた。(b) Background of the Invention Conventionally, a key top manufacturing method involves injection molding a rubber or resin material into a mold to form a predetermined key top shape, and then, as a subsequent process, as shown in FIG. A key top display symbol 52 is attached on the outer surface of the key top 51 by screen printing or the like, and a movable contact 53 is attached on the inner surface.
I was fixated on it.
しかし、このような印刷手段では、キートップ成形品の

にこれは印刷時に弾性変形しやすいゴム材に顕著である
。また、キートップの使用状態にあっては、キートップ
上に印刷された凹凸の表示記号のみに指が触れるため、
押下感触が悪く、さらに直接接触する表示記号が摩耗し
て消えや寸い問題を有していた。However, with such printing means, variations in the key top moldings tend to cause printing misalignment, smearing, etc., and this is particularly noticeable in rubber materials that tend to be elastically deformed during printing. In addition, when the key top is in use, your fingers only touch the uneven display symbols printed on the key top, so
The pressing feeling was poor, and the display symbols that were in direct contact with the display were worn out, causing problems such as fading and sizing.
（ハ）発明の目的
そこでこの発明は、印刷のズレ、にじみ等を解消し、か
つ表示記号のみに指が接触することのないキートップの
製造方法の提供を目的とする。(c) Purpose of the Invention Therefore, the object of the present invention is to provide a method for manufacturing a key top that eliminates printing misalignment, blurring, etc., and prevents fingers from touching only display symbols.
（ニ）発明の要約
この発明は、キートップを形成すべき金型のキ１１ビテ

この発明によれば、表示記号を印刷したフィルムを予め
金型内に貼着した状態で成形するため、キートップの成
形と同時に表示記号を成形することができる。(D) Summary of the Invention This invention provides keys that are molded with a film printed with display symbols such as letters and numbers to be displayed on the key top attached to the cavity of a mold in which the key top is to be formed. Effects of the invention characterized in that it is a method for manufacturing a key top.According to this invention, since the film on which the display symbol is printed is pasted in advance in a mold and then molded, there is no problem with the molding of the key top. Display symbols can be formed at the same time.
このため、キートップ成形後の後処理としての独立した
印刷手段が不要となり、製作工数を低減して確実に低コ
スト化できる。また、表示記号は金型のキャビティ内に
案内されて自ずと位置決めされた状態で成形されるため
、表示位置が正確であり、しかも表示記号はキートップ
の外表面に埋設された状態にあるため、指で触れＩＣ際
の違和感がなくなり、押下感触が良好で、表示記号の耐
摩耗性も良好となる。Therefore, an independent printing means for post-processing after key top molding is not required, and the number of manufacturing steps can be reduced to ensure cost reduction. In addition, since the display symbol is guided into the mold cavity and positioned automatically, the display position is accurate, and since the display symbol is embedded in the outer surface of the key top, There is no discomfort when touching the IC with a finger, the pressing feeling is good, and the abrasion resistance of the display symbol is also good.
（へ）発明の実施例 この発明の一実施例を以下図面に基づいて詳述する。(f) Examples of the invention An embodiment of the present invention will be described in detail below based on the drawings.

プを成形する。The drawings show a method of manufacturing key tops, and in Fig. 1,
The display symbol is molded simultaneously with the injection molding of the key top, with a film 14 on which the display symbol 13 is printed interposed between the upper mold 11 and the lower mold 12 for injection molding, A film 14 on which display symbols 13 such as letters and numbers to be displayed on the key tops are printed is pasted in the cavity 15 corresponding to the key top formed in the lower surface of the upper mold 11. After preforming in vacuum for mounting, liquid silicone rubber as a key top material is injected into a pair of upper and lower molds 11 and 12 to mold the key top.
なお、下金型１２の上面にはキートップ１６を保持する
シート部１７の凹部が形成される。Note that a recessed portion of the seat portion 17 for holding the key top 16 is formed on the upper surface of the lower mold 12.

在に、また元の押下位置に復帰づ゛べく設けられる。As shown in FIGS. 2 and 3, the above-mentioned key tops 16 are integrally formed into a sheet in the plane direction, with a required number of key tops, and these key tops 16 are thinner than the sheet portion 17. The key top 16 is protruded upward through an elastic support part 18, and the key top 16 is provided so that it can be pressed freely and returned to the original pressed position by this elastic support part 18.
上述の表示記号１３は、キャビティ１５内で位置ズレす

された可動接点１９が同時に一体的に溶着される。The above-mentioned display symbol 13 is printed with high precision since there is no room for displacement within the cavity 15, and the display symbol 13 is embedded in the top surface of the key top 16 so that it does not overlap the outer surface of the key top 16. Since the display symbol 13 is flush with the display symbol 13, the pressing contact only with respect to the display symbol 13 is eliminated. On the other hand, a movable contact 19, which is set in advance during injection molding, is simultaneously and integrally welded to the lower surface of the key top 16.

The upper surface of the key top 16 is provided in a depressable state protruding from the opening 22 of the key top 1, and a fixed contact 23 is fixed on the printed circuit board 20 below the movable contact 19 so as to be able to come into contact with it.
Each time the key top 16 is pressed, both contacts 19 and 23 come into contact with each other and an ON signal is obtained.
