Abstract
A key button and a method of manufacturing the same are provided. The key button includes an upper surface, a side surface formed at a certain height along a border of the upper surface, and at least two worked surfaces formed to have a certain slope in a boundary portion between the side surface and the upper surface, wherein at least one first worked surface and at least one second worked surface are formed such that a shortest distance between the upper surface and the side surface differs from each other.
Claims20
A key button comprising:
- an upper surface;
- a side surface formed along a border of the upper surface;
- and
- at least two worked surfaces formed to have a certain slope in a boundary portion between the side surface and the upper surface,
- wherein at least one first worked surface and at least one second worked surface are formed such that a shortest distance between the upper surface and the side surface differs from each other.
An electronic device comprising:
- a case frame;
- and
- at least one key button installed in the case frame such that a part thereof is exposed at a portion of the case frame,
- wherein at least the one key button includes an upper surface, a side surface formed along a border of the upper surface, and at least two worked surfaces formed to have a certain slope in a boundary portion between the side surface and the upper surface, and
- wherein at least one first worked surface and at least one second worked surface are formed such that a shortest distance between the upper surface and the side surface differs from each other.
A method of manufacturing a key button, the method comprising:
- preparing a basic material including an upper surface, and a side surface formed along a border of the upper surface;
- forming at least two worked surfaces by working the key button using a working tool to have a certain slope along a boundary portion between the side surface and the upper surface of the prepared basic material;
- and
- adjusting an amount of offset of the working tool such that a shortest distance between the upper surface and the side surface of at least one first worked surface and at least one second worked surface while forming at least the two worked surfaces are different from each other.
An electronic device comprising:
- a case frame;
- and
- a longitudinal key button installed in the case frame such that a part thereof is exposed at a portion of the case frame,
- wherein the longitudinal key button includes an upper surface, a side surface formed along a border of the upper surface, a pair of first worked surfaces formed between the side surface and the upper surface to have a certain slope in positions which are opposite to each other in a longitudinal direction of the longitudinal key button, and a pair of second worked surfaces formed between the side surface and the upper surface to have a certain slope in positions which are opposite to each other in a width direction of the longitudinal key button, and
- wherein a shortest distance between the upper surface and the side surface of the pair of first worked surfaces is formed to be greater than that of a shortest distance of the pair of second worked surfaces.
