Abstract

An electronic device having a multi-functional pointing device of a track ball in which a connecting part is arranged through which a shaft is connected so that the shaft is connected to the pointing device of track ball. When the shaft moves and pushes, the pointing device of the track ball swings correspondingly . So the track ball provides different operating interfaces so to alleviate the problem that a user needs to have a different pointing device of a track ball with a different control condition.

Claims

1. An electronic device having a multi-functional pointing device of a track ball comprising a main computer and a pointing device of a track ball electrically connected thereto, characterized in that the pointing device of a track ball has a connecting part through which a shaft is connected and the pointing device swings through a transmission from the shaft.

2. The electronic device as recited in claim 1, wherein the shaft is connected to the connecting part by a fastener.

3. The electronic device as recited in claim 1, wherein the shaft is connected to the connecting part by a screw.

4. The electronic device as recited in claim 3, wherein the shaft has an exterior screw at a bottom and the connecting part has an interior screw for locking and fixing thereto.

5. The electronic device as recited in claim 1, wherein the shaft is connected to the connecting part by a tenon.

6. The electronic device as recited in claim 5, wherein the shaft has at least one tenon(s) at a bottom and the connecting part has at least one fastener for locking and closing thereto.

7. The electronic device as recited in claim 5, wherein the shaft has a fastener at a bottom and the connecting part has the tenon locking and closing thereto.

8. The electronic device as recited in claim 1, wherein the connecting part is a depression on the pointing device of track ball.

9. The electronic device as recited in claim 1, wherein the connecting part is a fixing member on the pointing device of track ball.

10. The electronic device as recited in claim 1, wherein the fixing member is a screw.

11. The electronic device as recited in claim 1, wherein the connecting part is a shaft-like member when the connecting part protruding on a track point.

12. The electronic device as recited in claim 11, wherein the connecting part is the shaft-like member when the connecting part protruding on a track point.
