Abstract
A computer input device includes a button that is movable by an external force; an elastic unit that is positioned on a lower portion of the button, is deformed or compressed by the movement of the button, and provides an elastic force in response to the movement of the button; and a switch that is turned on or off by the movement of the button, wherein the button is movable in an on section, which is a section from an uppermost end position to a position where the switch is turned on, and an extra section, which is a section up to a position that is lower than the on section.
Claims11
A computer input device comprising:
- a button that is movable by an external force;
- an elastic unit that is positioned on a lower portion of the button, is deformed or compressed by the movement of the button, and provides an elastic force in response to the movement of the button;
- and
- a switch that is turned on or off by the movement of the button,
- wherein the button is movable in an on section, which is a section having a length defined from an uppermost end position to a position where the switch is turned on, and an extra section, which is a section having a length defined up to a position that is lower than the on section,
- wherein the elastic unit is a spring of which an elastic modulus continuously increases or decreases along a same direction as a direction of the external force, a portion having a relatively small elastic modulus is compressed by the external force in the on section, and a portion having a relatively large elastic modulus is compressed by the external force in an entirety or portion of the extra section.
