Abstract

The invention discloses a cover and an electronic apparatus with the cover. The cover is used for covering an opening of a casing of the electronic apparatus. The cover of the invention includes a covering body and a catching structure. Therein the covering body has an inner surface. When the opening is covered with the cover, the inner surface is toward the interior of the casing. The catching structure is formed on the inner surface for catching an object falling on the inner surface. The catching structure could be an adhesive layer or include a protrusive structure. If the catching structure is an adhesive layer, the object falling on the inner surface adheres to the adhesive layer. If the catching structure includes the protrusive structure, the object is confined by the protrusive structure.

Claims

1. A cover for covering an opening of a casing, the cover comprising:

a covering body having an inner surface, when the opening is covered with the cover, the inner surface is toward the interior of the casing; and

a catching structure formed on the inner surface, for catching an object falling on the inner surface.

2. The cover of claim 1, wherein the catching structure is a first adhesive layer for adhering the object.

3. The cover of claim 2, wherein the first adhesive layer is a twin adhesive tape.

4. The cover of claim 1, wherein the catching structure comprises a protrusive structure formed on the inner surface.

5. The cover of claim 4, wherein the protrusive structure comprises a plurality of protrusive columns.

6. The cover of claim 5, wherein a region of the inner surface is surrounded by the plurality of protrusive columns.

7. The cover of claim 6, wherein the catching structure comprises a second adhesive layer formed on the region for adhering the object.

8. The cover of claim 4, wherein the protrusive structure comprises a retaining wall.

9. The cover of claim 8, wherein a region of the inner surface is surrounded by the retaining wall.

10. The cover of claim 9, wherein the region is a closed region.

11. The cover of claim 9, wherein the catching structure comprises a second adhesive layer formed on the region for adhering the object.

12. The cover of claim 8, wherein a groove is formed between the retaining wall and the inner surface.

13. An electronic apparatus, comprising:

a casing having an opening;

a light source disposed in the casing; and

a cover for covering the opening, the cover comprising;

a covering body having an inner surface, when the opening is covered with the cover, the inner surface is toward the interior of the casing; and

a catching structure formed on the inner surface, for catching an object falling on the inner surface.

14. The electronic apparatus of claim 13, wherein the catching structure is a first adhesive layer for adhering the object.

15. The electronic apparatus of claim 14, wherein the first adhesive layer is a twin adhesive tape.

16. The electronic apparatus of claim 13, wherein the catching structure comprises a protrusive structure formed on the inner surface.

17. The electronic apparatus of claim 16, wherein the protrusive structure comprises a plurality of protrusive columns.

18. The electronic apparatus of claim 17, wherein a region of the inner surface is surrounded by the plurality of protrusive columns.

19. The electronic apparatus of claim 18, wherein the catching structure comprises a second adhesive layer formed on the region for adhering the object.

20. The electronic apparatus of claim 16, wherein the protrusive structure comprises a retaining wall.

21. The electronic apparatus of claim 20, wherein a region of the inner surface is surrounded by the retaining wall.

22. The electronic apparatus of claim 21, wherein the region is a closed region.

23. The electronic apparatus of claim 21, wherein the catching structure comprises a second adhesive layer formed on the region for adhering the object.

24. The electronic apparatus of claim 20, wherein a groove is formed between the retaining wall and the inner surface.

25. The electronic apparatus of claim 13, wherein the light source is disposed toward the opening.

26. The electronic apparatus of claim 13, wherein the light source is a projection light source.
