LIGHT-EMITTING BUTTON KEY AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a light-emitting button key and a manufacturing method thereof. The manufacturing method in which a symbol printed on the button key is lightened when light is emitted from a rear side thereof, includes a pressing step of pressing a metal plate and forming a button body which is opened in one direction; an adhesive coating step of coating an adhesive in the button body; an injection-molding step of injecting a synthetic resin formed of a transparent or semitransparent material into the button body in which an adhesive layer is formed by the adhesive so that a penetration part bonded to the button body through the adhesive layer is injection-molded; and a groove machining step of penetrating the button body and adhesive layer from an outside of the button body and thus forming a light transmission groove corresponding to a character, number or symbol, wherein the light transmission groove formed in the groove machining step is not passed through the penetration part, and the light emitted from the rear side of the button body is radiated to an outside through the penetration part and light transmission groove so as to lighten the character, number or symbol formed in the light transmission groove.

主权项

1. A light-emitting button key in which a symbol printed on the button key is lightened by light emitted from a rear side, comprising:
a button body which is formed of a metal material to be opened in one direction and in which an etching groove is formed to provide a thin thickness; an adhesive layer which is coated on the etching groove formed in the button body; and a penetration part which is formed of a transparent or semitransparent synthetic resin and bonded to an inside of the button key through the adhesive layer, wherein a light transmission groove having a corresponding shape to a character, number or symbol is formed to penetrate the button body and adhesive layer but not the penetration part, and the light emitted from the rear side of the button body is radiated to an outside through the penetration part and light transmission groove so as to lighten the character, number or symbol formed in the light transmission groove.
