Abstract

An optical apparatus includes a main body, a reflecting object lens pivotally connected to the main body and a cover pivotally connected to the reflecting object lens. The reflecting object lens is rotatable with respect to the main body within a first angle, and the cover is rotatable with respect to the reflecting object lens within a second angle.

First claim

What is claimed is:

1. An optical apparatus, comprising:
a main body comprising a linkage structure, wherein the linkage structure comprises a first hook;
a reflecting object lens pivotally connected to the main body, wherein the reflecting object lens is rotatable with respect to the main body within a first angle; and
a cover pivotally connected to the reflecting object lens, wherein the cover is rotatable with respect to the reflecting object lens within a second angle.

2. The optical apparatus as claimed in claim 1 , further comprising a pivot, wherein the reflecting object lens is pivotally connected to the main body through the pivot.

3. The optical apparatus as claimed in claim 1 , further comprising a pivot, wherein the cover is pivotally connected to the reflecting object lens through the pivot.

4. The optical apparatus as claimed in claim 2 , further comprising an elastic element disposed on the pivot, wherein the elastic element is deformed with an elastic force generated and stored therein when the optical apparatus is closed, and the elastic force is released when the optical apparatus is opened.

5. The optical apparatus as claimed in claim 4 , wherein the elastic element is a torsion spring or a flat spring.

6. The optical apparatus as claimed in claim 3 , further comprising an elastic element disposed on the pivot, wherein the elastic element is deformed with an elastic force generated and stored therein when the optical apparatus is closed, and the elastic force is released when the optical apparatus is opened.

7. The optical apparatus as claimed in claim 6 , wherein the elastic element is a torsion spring or a flat spring.

8. The optical apparatus as claimed in claim 1 , wherein the main body further comprises a switch;
wherein the switch comprises a first inclined plane;
wherein the linkage structure further comprises a second hook and a second inclined plane;
wherein the first inclined plane is placed against the second inclined plane;
wherein the first inclined plane slides with respect to the second inclined plane to move the linkage structure when the switch is operated.

9. The optical apparatus as claimed in claim 8 , wherein the reflecting object lens further comprises a third hook configured to detachably connect to the first hook.

10. The optical apparatus as claimed in claim 8 , wherein the cover further comprises a third hook configured to detachably connect to the second hook.

11. The optical apparatus, comprising:
a main body;
a reflecting object lens pivotally connected to the main body, wherein the reflecting object lens is rotatable with respect to the main body within a first angle;
a cover pivotally connected to the reflecting object lens, wherein the cover is rotatable with respect to the reflecting object lens within a second angle;
a light source; and
a reflecting mirror, wherein the light source is configured to produce a first light beam, and the reflecting mirror is configured to reflect the first light beam to the reflecting object lens.

12. The optical apparatus as claimed in claim 11 , further comprising a mask, wherein the mask comprises at least one transparent portion, and the first light beam passes through the transparent portion to be shaped.

13. The optical apparatus as claimed in claim 11 , further comprising a mask, wherein the mask comprises a plurality of transparent portions with different shapes, switched to generate different shaped light beams when the first light beam passes through the transparent portions to be shaped.

14. An optical apparatus, comprising:
a main body;
a reflecting object lens pivotally connected to the main body, wherein the reflecting object lens is rotatable with respect to the main body within a first angle;
a light source configured to produce a first light beam;
a mask comprising at least one transparent portion, wherein the first light beam passes through the transparent portion to be shaped; and
a reflecting mirror configured to reflect the first light beam to the reflecting object lens.

15. The optical apparatus as claimed in claim 14 , wherein the main body comprises a switch and a linkage structure, the switch comprises a first inclined plane, the linkage structure comprises a first hook, a second hook and a second inclined plane, the first inclined plane is placed against the second inclined plane, and the first inclined plane slides with respect to the second inclined plane to move the linkage structure when the switch is operated.

16. The optical apparatus as claimed in claim 14 , wherein a second light beam emitted by an object passes through the reflecting object lens.

17. The optical apparatus as claimed in claim 16 , wherein the first light beam or the second light beam passes through the transparent portion to be shaped.

18. The optical apparatus as claimed in claim 17 , wherein the transparent portion is in a shape of reticle, crosshair, target dot, or circle.

19. The optical apparatus as claimed in claim 14 , further comprising a pivot, wherein the reflecting object lens is pivotally connected to the main body through the pivot.

20. The optical apparatus as claimed in claim 19 , further comprising an elastic element disposed on the pivot, wherein the elastic element is deformed with an elastic force generated and stored therein when the optical apparatus is closed, and the elastic force is released when the optical apparatus is opened.
