Abstract

A driving device includes a base and a conductive pattern portion provided on a surface of the base. The conductive pattern portion has a finger touch portion, touching portions and conductive connecting portions connecting the finger touch portion and each of the touching portions. When a surface of the base is contacted with a multi-touch display of an information processor, each of the touching portions activates a corresponding touching area of the multi-touch display. Thus, a predetermined action is executed by the information processor.

Claims

1. A driving device adapted to be connected to an information processing device having a capacitive multi-touch display, comprising:

a base made of an electrically insulating body; and

a conductive pattern portion disposed at one side surface of the base;

wherein the driving device serves to cause the information processing device to execute a proper action when the driving device is touched with the multi-touch display;

wherein the conductive pattern portion has a finger touch portion, a conductive connecting portion and a plurality of touching portions;

wherein each of the touching portions is made of an electrically conductive body having a touching area of a predetermined dimension that comes into a touched or nearly touched state with the multi-touch display;

wherein the finger touch portion is made of a planar shape of conductive body layer provided on one end portion of the base;

wherein the conductive connecting portion is made of an electrically conductive body electrically connecting the finger touch portion and each of the touching portions;

wherein the touching area of each of the touching portions is set at a value not less than a minimum detection area of the multi-touch display;

wherein the conductive connecting portion is provided on the base so as to be kept from activating a touching area of the multi-touch display by a capacitive coupling between the touching area of the multi-touch display and itself; and

wherein the finger touch portion is provided on the one end portion of the base only at a predetermined location where a finger of a user naturally touches.

2. A driving device according to claim 1, wherein the finger touch portion is provided at the predetermined location on the one end portion of the base by a minimum area.

3. A driving device according to claim 1, wherein the connecting portion has a width less than 1 mm.

4. A driving device according to claim 1, wherein the conductive pattern portion is formed on the one side surface of the base by a silk screen printing of 350 meshes or more.

5. A driving device according to claim 1, further comprising a shielding member shielding the conductive pattern portion on the one side surface of the base, wherein the shielding member has a thickness and is made of a material that do not hinder a capacitance change by the touching portion so that the touching portion changes the capacitance of the multi-touch display through the shielding member.

6. A driving device according to claim 1,

wherein the base has a plurality of base sheets of a same rectangular shape, the base sheet having a shape coupling the plurality of base sheets in a width direction thereof so that the base sheets are capable of being folded and overlapped on each other,

wherein the base sheets have cutouts at one ends thereof, respectively,

wherein the conductive pattern portion has the conductive connecting portion and the touching portions formed on one side surfaces of the base sheets, respectively,

wherein the conductive connecting portion is composed of a contact connecting portion and non-contact connecting portion,

wherein the contact connecting portion extend at a position near and along an edge of the cutout to constitute the finger touch portion, a leading end of the contact connecting portion extends to the one end of the base sheet, while a base end of the contact connecting portion extends to a base end of the base sheet,

wherein the non-contact connecting portion electrically extends from the base end of the contact connecting portion to an inside of the base sheet to provide electrical conduction between the contact connecting portion and the touching portion, and

wherein the touching portion is allowed to be electrically conductive with the finger of the user via the contact connecting portion when the finger of the user comes into touched state with the contact connecting portion so as to change the capacitance of corresponding touching areas of the multi-touch display of the information processing device.
