Abstract

A mouse according to the present invention, comprises: a casing; a button part disposed on the casing, for generating a click signal by being pressed; and a sensing part fixedly disposed on the casing in the vicinity of the button part in such a fashion as to be slantedly lower than the button part; an amplifying part built in the casing, for amplifying the clock signal generated from the sensing part, up to a predetermined level; a filtering part built in the casing, for regulating the signal amplified by the amplifying part, up to a predetermined level; and a switching part for outputting selectively and one from the signals applied thereto from the button part and the sensing part. Since the mouse operates in a touch-sensor fashion, clicking noise is avoided when in use.

Claims

1. A mouse comprising:

a button part for generating a signal by clicking a plurality of buttons;

a sensing part fixedly disposed at a position of a casing where it can be manipulated by a user'"'"'s finger, and adapted to generate a signal by bodily touching, so that a clicking operation identical to that of at least one button of the button part can be performed;

an amplifying part for amplifying a clock signal generated by the sensing part, up to a predetermined level;

a filtering part for regulating the signal amplified by the amplifying part, up to a predetermined level;

a switching part for selectively outputting one from the signals applied thereto from the button part and the sensing part; and

a signal processing part for processing the signal applied thereto from the switching part, and transmitting the processed signal to a computer.

2. The mouse according to claim 1, wherein the switching part does not respond to the signals simultaneously applied thereto from both the button part and the sensing part.

3. The mouse according to claim 1, wherein the sensing part is disposed at a front end of the button part along the longitudinal direction.

4. The mouse according to claim 1, wherein the sensing part is disposed beside the button part in the traversing direction.

5. The mouse according to claim 1, wherein a sensing part corresponding to a left button of a mouse, is disposed either in the vicinity of the left button of the mouse or at the place where a thumb is situated, or both.

6. The mouse according to claim 5, wherein a sensing part manipulated by a thumb is formed in a higher position than a typical thumbing position.

7. The mouse according to claim 1, wherein a longitudinal partitioning protrusion is further formed at the border between the sensing part and the button part.

8. The mouse according to claim 1, wherein the sensing part includes any one selected from the group consisting of a proximate sensor, a resistive temperature sensor, a pressure sensor, a distance measuring sensor, an infrared sensor, a magnetic sensor, and a touch sensor, for sensing the bodily touching.

10. The mouse according to claim 3, wherein a longitudinal partitioning protrusion is further formed at the border between the sensing part and the button part.

11. The mouse according to claim 4, wherein a longitudinal partitioning protrusion is further formed at the border between the sensing part and the button part.

12. The mouse according to claim 5, wherein a longitudinal partitioning protrusion is further formed at the border between the sensing part and the button part.

9. A mouse comprising:

a casing having a drive circuit built therein;

a button disposed on the casing, for generating a click signal by being pressed; and

a support member elongatedly formed on the casing along the button part, for parallelly supporting the sensing part with regard to the button part,

wherein the drive circuit comprises;

a sensor for sensing a click signal according to a variation in capacitance of a first capacitor connected thereto in parallel;

an OP-amp connected to the sensor, for amplifying the click signal applied thereto from the sensor up to a predetermined level, according to a magnitude of a variable resistor connected to the other input port of the OP-amp;

a transistor connected to an output port of the OP-amp, for regulating the click signal applied thereto from the OP-amp up to a predetermined level;

a button for generating a click signal by varying capacitance of a second capacitor connected therewith in parallel; and

a logic operator connected to the transistor and the button, for processing in an RS flip-flop scheme the click signal applied thereto from the transistor and the button.
