Abstract

An exemplary input apparatus, includes a flexible input panel, a reel, a stylus and an image capturing apparatus. The reel includes a casing and a rotatable spindle, the casing defining an inner space and an opening communicating the inner space, the rotatable spindle being received in the inner space and configured for winding the input panel into the inner space of the casing and unwinding the input panel out of the casing through the opening. The stylus is configured for input information to the input panel. The image capturing apparatus is mounted on the casing and configured for obtaining the information inputted to the input panel by the stylus.

Claims

1. An input apparatus, comprising:

a flexible input panel; and

a reel comprising a casing and a rotatable spindle, the casing defining a tubular inner space and an opening communicating the inner space, the rotatable spindle being received in the inner space and configured for winding the input panel thereon so as to cause the wound input panel to be received in the inner space and unwinding the wound input panel to cause the unwound input panel to extend out of the inner space through the opening.

2. The input apparatus as described in claim 1, wherein the rotatable spindle has a handle extending out of the casing.

3. The input apparatus as described in claim 1, wherein the inner space is cylindrical.

4. The input apparatus as described in claim 1, further comprising an image capturing apparatus, the reel further comprising a pole positioned on the casing, and the pole configured for supporting the image capturing apparatus.

5. The input apparatus as described in claim 1, wherein a refractive index of the input panel is not less than 0.7.

6. An input apparatus, comprising:

a flexible input panel;

a reel comprising a casing and a rotatable spindle, the casing defining an inner space and an opening communicating the inner space, the rotatable spindle being received in the inner space and configured for winding the input panel thereon to cause the wound input panel to be received in the inner space of the casing and releasing the wound input panel out of the casing through the opening;

a stylus configured for input information to the input panel; and

an image capturing apparatus mounted on the casing and configured for obtaining the information inputted to the input panel by the stylus.

7. The input apparatus as described in claim 6, wherein the rotatable spindle has a handle extending out of the casing.

8. The input apparatus as described in claim 6, wherein the inner space is cylindrical.

9. The input apparatus as described in claim 6, wherein the reel further comprises a pole positioned on the casing, the image capturing apparatus is supported by the pole.

10. The input apparatus as described in claim 6, wherein a tip of the stylus is capable of emitting infrared light, and the image capturing apparatus configured for capturing infrared images of the tip, thereby obtaining the information inputted to the input panel based on location of the tip or movement of the tip on the input panel.

11. The input apparatus as described in claim 10, wherein a refractive index of the input panel to the infrared light is not less than 0.7.

12. An input apparatus, comprising:

a flexible input panel;

a reel comprising a casing and a rotatable spindle, the casing defining an inner space and an opening communicating the inner space, the rotatable spindle being received in the inner space and configured for winding the input panel into the inner space of the casing and unwinding the input panel out of the casing through the opening; and

an image capturing apparatus supported by the casing and configured for capturing images of the information inputted to the input panel.
