Abstract

A wireless pointing device with forced power-off function includes a body and a power supply switch. The body includes a pointing module, a battery, and a wireless transmission module. The wireless transmission module transmits an indication signal providing from the pointing module. The power supply switch is located on an outer surface of the body to control ON and OFF of the power supply circuit of the battery. The power supply switch may be cut off manually, or through charging operation to completely cut off the power of the wireless pointing device to avoid electric power consumption and increase the service life of the battery.

Claims

1. A wireless pointing device with forced power-off function, comprising:

a body having a power supply circuit connecting to a power supply; and

a power supply switch located on a surface of the body;

wherein the body further includes a pointing module and a wireless transmission module for transmitting an indicating signal from the pointing module to a computer system, and the power supply circuit providing electricity from the power supply to the pointing module and the wireless transmission module;

wherein the power supply switch controls a connection and a disconnection between the power supply circuit and the power supply.

2. The wireless pointing device of claim 1, wherein the power supply switch is pressed by a compression section of a charge device to cause the disconnection.

3. The wireless pointing device of claim 2, wherein the charge device charges the wireless pointing device when the wireless pointing device is at a first position;

and the power supply switch is pressed to be disconnection by the compression section at a second position.

4. The wireless pointing device of claim 3, wherein the first position and the second position are located on a same motion track.

5. The wireless pointing device of claim 4, wherein the wireless pointing device moves horizontally to reach the first position and the second position.

6. The wireless pointing device of claim 4, wherein the wireless pointing device moves vertically to reach the first position and the second position.

7. The wireless pointing device of claim 4, wherein the wireless pointing device horizontally rotates to reach the first position and the second position.

8. The wireless pointing device of claim 1, wherein the body further includes two electrode contacts, and the power supply is a chargeable battery.

9. The wireless pointing device of claim 2, wherein the power supply switch is a ON and OFF button.

10. The wireless pointing device of claim 1, wherein the power supply switch is a linear-moving switch.

11. The wireless pointing device of claim 1, wherein the power supply is a regular battery.

12. The wireless pointing device of claim 2, wherein the charge device further combines with a wireless receiver or a wireless transceiver.
