Multi-functional touch keyboard having touch sensor
The present invention discloses a multi-functional touch keyboard having a touch sensor, including: a key cap unit 110 ; a driving circuit unit (not shown); a support 120 ; a touch pad 130 composed of touch sensors respectively formed on the upper ends of multiple key caps 111 grouped in a specific shape; a left click key 141 and a right click key 142 formed adjacent to both ends of the touch pad 130 ; and a control unit (not shown) which moves a cursor in conjunction with a touch of the touch pad 130 and performs a click function by means of pressing of the click key, in which the multi-functional touch keyboard performs a touch pad function as a graphic controller while performing basic functions as a keyboard.
1. A multi-functional touch keyboard having a touch sensor, comprising:
a key cap unit with a character key cap, a function key cap, a numeric key cap, a special key cap, and a direction key cap;
a driving circuit unit constituted by a contact point and a membrane switch each coupled to a lower end of a corresponding key cap of the key cap unit;
a support supporting the membrane switch;
a touch pad constituted by touch sensors formed on upper ends of the multiple key caps groped in a specific shape, respectively;
a left click key and a right click key formed adjacent to both ends of the touch pad; and
a control unit moving a cursor in conjunction with a touch of the touch pad and performing a click function by pressing the click keys,
wherein the multi-functional touch keyboard performs a touch pad function as a graphic controller while performing basic functions as a keyboard,
wherein the touch pad is formed by grouping up to the character key caps in a reverse triangular form based on a space key cap,
wherein the click key is formed on each of both ends of the space key cap,
wherein the touch sensor is formed on each of upper ends of the space key cap, six key caps on a lower line of the character key cap, seven key caps of an intermediate line, and eight key caps of an upper line,
wherein the key cap unit and the touch pad are disposed at a touch pad of a laptop computer or a lower palm rest location,
wherein a partition having a predetermined height is formed on an upper periphery of the corresponding key cap constituting an outline of the touch pad to separate a touch area of the touch pad, and
wherein a horizontal scroll is performed by horizontally touching a touch pad area on an upper end surface of the space key cap in conjunction with double strokes of the right click key, a vertical scroll is performed by vertically touching the touch pad area except for the space key cap, a left click and double clicks are performed by a stroke and double strokes of the left click key, and a right click is performed by a stroke of the right click key.
2. The multi-functional touch keyboard having a touch sensor of claim 1 , wherein the corresponding key cap constituting the outline of the touch pad and another adjacent key cap are formed spaced apart from each other at a predetermined distance to separate the touch area of the touch pad.
