Claims10
An input device for a computer, comprising:
- a main body unit having a receiving space provided therein:
- a button unit provided to a top of the main body unit so as to be clickable;
- an elastic unit configured to restore the button unit to its original state when clicking on the button unit is released;
- and
- a switch unit provided within the receiving space and subjected to an ON operation or an OFF operation depending on whether the button unit is clicked on,
- wherein the button unit further moves by a given depth in a state in which the switch unit maintains the ON operation after being subjected to the ON operation,
- wherein a manipulation bar for ON/OFF operating the switch unit protrudes downward on an inner circumference surface of the button unit,
- wherein the switch unit comprises an optical transmitter configured to generate a light beam and a first optical receiver disposed to face the optical transmitter and configured to receive the light beam generated by the optical transmitter, wherein when the button unit is not clicked on, the first optical receiver maintains an OFF state by receiving the light beam generated by the optical transmitter, and when the button unit is clicked on, a lower end of the manipulation bar blocks the light beam so that the OFF state is charged to an ON state,
- wherein the switch unit further comprises a second optical receiver disposed on one side of the optical transmitter and configured to receive a light beam of the optical transmitter which is reflected from a surface of the manipulation bar at a moment when the lower end of the manipulation bar changes the OFF state to the ON state by blocking the light beam between the optical transmitter and the first optical receiver when the button unit is clicked on,
- wherein the manipulation bar is formed in a wedge shape having a wide top and narrow bottom, and converts, into a given signal, an amount of reflection of a light beam according to reflection distances of the light beam, differently formed depending on a degree to which the manipulation bar is lowered, through a control unit, and
- the given signal is used as analog input means within a computer.

- a first section which is an isolated distance between the fixed stage and the contact type button;
- and
- a second section which is an isolated distance between the contact type button and the free stage, and
- wherein the second section is formed to be longer than the first section.
