Abstract

A notebook computer having projection function includes a mainframe, a display, and a compact projector. The compact projector is pivotally disposed at the upper portion of a frame area, and is electrically connected with the mainframe so as to receive signals therefrom. The compact projector projects images identical to those shown from the display toward a direction opposite to a displaying direction from a screen area. Therefore, people located at opposite sides of the notebook computer can view simultaneously identical images, without a need to move to the side, to which the screen displays, so as to enhance convenience of communication between the parties.

Claims

1. A notebook computer having projection function, comprising:

a mainframe;

a display, being pivotally and electrically connected with the mainframe, and including a screen area, a frame area, and a rear portion located at a backside of the screen area, wherein the frame area surrounds the screen area, and the display receives signals from the mainframe and displays corresponding images on the screen area; and

a compact projector, being pivotally disposed at an upper portion of the frame area, and being electrically connected with the mainframe so as to receive signals therefrom and to project the corresponding images.

2. The notebook computer having projection function as claimed in claim 1, further comprising a projecting screen pivotally connected with the mainframe.

3. The notebook computer having projection function as claimed in claim 1, further comprising a projecting screen pivotally connected with the rear portion of the display.

4. The notebook computer having projection function as claimed in claim 1, further comprising a projecting screen slidably disposed in a drawer underneath the mainframe, such that the projecting screen can reach to an appropriate projection position.

5. The notebook computer having projection function as claimed in claim 1, wherein the compact projector is disposed on a rotating frame which is pivotally supported on the frame area of the display by a pin.

6. The notebook computer having projection function as claimed in claim 5, further comprising a web camera disposed on the rotating frame.

7. The notebook computer having projection function as claimed in claim 5, further comprising a web camera disposed on a second rotating frame which is pivotally supported on the frame area of the display by another pin.

8. The notebook computer having projection function as claimed in claim 2, wherein the compact projector is disposed on a rotating frame which is pivotally supported on the frame area of the display by a pin.

9. The notebook computer having projection function as claimed in claim 8, further comprising a web camera disposed on the rotating frame.

10. The notebook computer having projection function as claimed in claim 8, further comprising a web camera disposed on a second rotating frame which is pivotally supported on the frame area of the display by another pin.

11. The notebook computer having projection function as claimed in claim 3, wherein the compact projector is disposed on a rotating frame which is pivotally supported on the frame area of the display by a pin.

12. The notebook computer having projection function as claimed in claim 11, further comprising a web camera disposed on the rotating frame.

13. The notebook computer having projection function as claimed in claim 11, further comprising a web camera disposed on a second rotating frame which is pivotally supported on the frame area of the display by another pin.

14. The notebook computer having projection function as claimed in claim 4, wherein the compact projector is disposed on a rotating frame which is pivotally supported on the frame area of the display by a pin.

15. The notebook computer having projection function as claimed in claim 14, further comprising a web camera disposed on the rotating frame.

16. The notebook computer having projection function as claimed in claim 14, further comprising a web camera disposed on a second rotating frame which is pivotally supported on the frame area of the display by another pin.

17. The notebook computer having projection function as claimed in claim 2, wherein the projecting screen is a digital pad electrically connected with the mainframe.

18. The notebook computer having projection function as claimed in claim 3, wherein the projecting screen is a digital pad electrically connected with the mainframe.

19. The notebook computer having projection function as claimed in claim 4, wherein the projecting screen is a digital pad electrically connected with the mainframe.

20. The notebook computer having projection function as claimed in claim 2, wherein the projecting screen is provided with a clip.

21. The notebook computer having projection function as claimed in claim 3, wherein the projecting plate is provided with a clip.

22. The notebook computer having projection function as claimed in claim 4, wherein the projecting plate is provided with a clip.

23. The notebook computer having projection function as claimed in claim 2, wherein the projecting screen is covered with metal, white cloth, or tripod screen.

24. The notebook computer having projection function as claimed in claim 3, wherein the projecting screen is covered with metal, white cloth, or tripod screen.

25. The notebook computer having projection function as claimed in claim 4, wherein the projecting screen is covered with metal, white cloth, or tripod screen.

26. The notebook computer having projection function as claimed in claim 2, wherein the mainframe is pivotally provided underneath a pivotal support which is pivoted outward from underneath the mainframe so as to support and raise the display.

27. The notebook computer having projection function as claimed in claim 3, wherein the mainframe is pivotally provided underneath a pivotal support which is pivoted outward from underneath the mainframe so as to support and raise the display.

28. The notebook computer having projection function as claimed in claim 4, wherein the mainframe is pivotally provided underneath a pivotal support which is pivoted outward from underneath the mainframe so as to support and raise the display.
