Abstract

A stylus device capable of switching color is applied to an electronic device provided with a touch panel and comprises a body, several light-emitting devices, and an adjustment portion. The body has a plurality of holes and a pointer. The light-emitting devices are disposed in the hole, and each of which projects the light with various colors. The adjustment portion is disposed on the body, the surface of which has several colors. When the adjustment portion is adjusted to make the pointer point to one of the colors on the adjustment portion, the light-emitting devices generate the color light corresponding to the pointed color for making the body show the pointed color; when the stylus device is used for the touch panel, the color also can be shown on the touch panel.

Claims

1. A stylus device capable of switching color, applied to an electronic device provided with a touch panel and comprising:

a body;

a plurality of light-emitting devices disposed in the body and respectively projecting the light of various colors; and

an adjustment portion disposed on the body, the surface of the adjustment portion having a plurality of colors corresponding to the colors of light-emitting devices;

wherein, when the adjustment portion is operated to make the pointer point to one of colors on the adjustment portion, at least one of the light-emitting devices emits a light color for making the body show the pointed color; and

while the stylus device is used for the touch panel, the color also can be shown on the touch panel.

2. The stylus device of claim 1, wherein the electronic device is a portable electronic device.

3. The stylus device of claim 1, wherein the body is provided with a plurality of holes and the light-emitting devices are disposed in the holes.

4. The stylus device of claim 1, wherein the body is provided with a pointer that is used to point to one of the colors on the adjustment portion.

5. The stylus device of claim 1, wherein the body comprises:

an outer shell having an accommodating space formed with an inner side; and

an inner layer formed in the accommodating space, a surface of the inner layer capable of reflecting the light and kept from the inner side at a distance, and the light generated by light-emitting devices being refracted between the inner side and the surface.

6. The stylus device of claim 1, wherein the light-emitting devices are light-emitting diodes (LED).

7. The stylus device of claim 1, wherein the amount of light-emitting devices is corresponding to the amount of colors on the adjustment portion.

8. The stylus device of claim 1, further comprising a signal transmitter for transmitting a signal corresponding to the color which is pointed.

9. The stylus device of claim 8, wherein the signal transmitter transmits the signal in the manner of Bluetooth transmission, WiFi, or RFID.

10. The stylus device of claim 8, wherein the electronic device is provided with a signal receiver for receiving the signal.

11. A stylus device capable of switching color, applied to an electronic device provided with a touch panel and comprising:

a body;

a plurality of light-emitting devices disposed in the body and respectively projecting the light of various colors; and

an adjustment portion disposed on the body, the surface of which is formed with a plurality of colors;

wherein, when the adjustment portion is adjusted to make the pointer point to one of the colors on the adjustment portion, at least one light generated by the light emitting devices are mixed to make the body show the pointed color; and

while the stylus device is used for the touch panel, the color can shown on the touch panel.

12. The stylus device of claim 11, wherein the electronic device is a portable electronic device.

13. The stylus device of claim 11, wherein the body is provided with a plurality of holes and the light-emitting devices are disposed in the holes.

14. The stylus device of claim 11, wherein the body is provided with a pointer that is used to point to one of the colors on the adjustment portion.

15. The stylus device of claim 11, wherein the body comprises:

an outer shell having an accommodating space formed with an inner side; and

an inner layer formed in the accommodating space, a surface of the inner layer capable of reflecting the light and kept from the inner side at a distance, and the light generated by light-emitting devices being refracted between the inner side and the surface.

16. The stylus device of claim 11, wherein the color on the surface of adjustment portion may be projected with the light generated by at least one of the light-emitting devices.

17. The stylus device of claim 11, further comprising a signal transmitter for transmitting a signal corresponding to the color which is pointed.

18. The stylus device of claim 17, wherein the signal transmitter transmits the signal in the manner of Bluetooth transmission, WiFi, or RFID.

19. The stylus device of claim 17, wherein the electronic device is provided with a signal receiver for receiving the signal.

20. A stylus device capable of switching color, applied to an electronic device provided with a touch panel and comprising:

a body;

an adjustment portion disposed on the body, the surface of the adjustment portion having a plurality of colors; and

wherein, when the adjustment portion is operated to make the pointer point to one of colors on the adjustment portion, and while the stylus device is used for the touch panel, the pointed color also can be shown on the touch panel.
