Abstract
A keytop plate comprises keytops (21) formed by integrally molding a molding resin part (25) with a synthetic resin film (23), and a molded elastomer sheet (molded elastomer member) (11) attached to the keytops (21). The molded elastomer sheet (11), other than in the areas to which the keytops (21) are attached, has no through-holes, whereby a water-proof property is provided. The keytops (21) are easily depressed even when the molded elastomer sheet (11) is securely held at its peripheral portion. A hard tactile feeling may be obtained when the keytops (21) are depressed, since the keytops (21) are formed from the synthetic resin film (23) and the molding resin part (25).
Claims11
A method for producing a keytop plate, comprising:
- molding a molding resin at predetermined positions of a synthetic resin film so as to form a plurality of keytops;
- attaching a molded elastomer member to said keytops;
- and
- removing at least a major portion of said synthetic resin film around each of said keytops, while leaving said molded elastomer member.
A keytop plate comprising:
- a plurality of keytops, each of said keytops having a molded resin part and a synthetic resin film, and each of said keytops being formed by integrally molding said molded resin part with said synthetic resin film;
- and
- a molded elastomer sheet, said plurality of keytops being attached to a surface of said molded elastomer sheet.
