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.
Claims11
A key button, comprising:
- an upper surface;
- a side surface formed along a border of the upper surface, the side surface including:
- a first side surface portion and a second side surface portion facing each other in a first direction and having a same first length, and
- a third side surface portion and a fourth side surface portion facing each other in a second direction perpendicular to the first direction and having a same second length, which is shorter than the first length;
- and
- at least two worked surfaces formed to have a certain slope along a boundary portion between the side surface and the upper surface, the at least two worked surfaces including:
- a first worked surface and a second worked surface corresponding to the first side surface portion and the second side surface portion, respectively, and having a same first interval between the upper surface and the first side surface or the second side surface with a first distance, and
- a third worked surface and a fourth worked surface corresponding to the third side surface portion and the fourth side surface portion, respectively, and having a second interval between the upper surface and the third side surface or fourth side surface,
- wherein a shortest second distance among the second interval is formed to be greater than the first distance,
- wherein at least a portion of the third worked surface and the fourth worked surface includes a third distance formed to be greater than the shortest second distance, and
- wherein the portion of the third side surface portion and the fourth side surface portion corresponding to the at least a portion of the third worked surface and the fourth worked surface is relatively less exposed from a case frame of an electronic device to remove a feeling of sharpness in a portion of the key button having a relatively shorter length.

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, the side surface including:
- a first side surface portion and a second side surface portion facing each other in a first direction and having a same first length, and
- a third side surface portion and a fourth side surface portion facing each other in a second direction perpendicular to the first direction and having a same second length, which is shorter than the first length;
- and
- at least two worked surfaces formed to have a certain slope along a boundary portion between the side surface and the upper surface, the at least two worked surfaces including:
- a first worked surface and a second worked surface corresponding to the first side surface portion and the second side surface portion, respectively, and having a same first interval between the upper surface and the first side surface or the second side surface with a first distance, and
- a third worked surface and a fourth worked surface corresponding to the third side surface portion and the fourth side surface portion, respectively, and having a second interval between the upper surface and the third side surface or the fourth side surface,
- wherein a shortest second distance among the second interval is formed to be greater than the first distance,
- wherein at least a portion of the third worked surface and the fourth worked surface includes a third distance formed to be greater than the shortest second distance, and
- wherein the portion of the third side surface portion and the fourth side surface portion corresponding to the at least a portion of the third worked surface and the fourth worked surface is relatively less exposed from the case frame of the electronic device to remove a feeling of sharpness in a portion of the key button having a relatively shorter length.
