Abstract

A camera module includes a lens module including lenses and a reflecting module disposed in front of the lens module. The reflecting module is configured to change a path of light to direct the light toward the lens module. The reflecting module includes a holder in which a reflecting member configured to change the path of the light is mounted and a first housing supporting the holder. The holder is configured to slide with respect to the first housing to enable rotation of the reflecting member with respect to a first axis and a second axis.

First claim

What is claimed is:

wherein the holder is configured to rotate about a first axis direction and a second axis direction with respect to the first housing, and
wherein the holder is disposed on the first housing in a direction perpendicular to the first and second axes.

2. The reflecting module of claim 1 , wherein the holder is pressed toward the first housing in the direction perpendicular to the first and second axes.

3. The reflecting module of claim 2 , wherein a first yoke is disposed on one surface of facing surfaces of the holder and the first housing, and a magnet is disposed on the other surface, and wherein the first yoke and the magnet are configured to magnetically attract each other to press the holder toward the first housing in the direction perpendicular to the first and second axes.

4. The reflecting module of claim 3 , wherein the first yoke is one or more of a magnetic material and a magnet.

5. The reflecting module of claim 1 , wherein the path of light is changed from a direction of the second axis to the direction perpendicular to the first and second axes.

6. The reflecting module of claim 1 , wherein first driving magnets are mounted in the holder, and coils, respectively facing the first driving magnets, are disposed in the first housing.

7. The reflecting module of claim 6 , wherein coils respectively face first driving magnets in a direction of the first axis.

8. The reflecting module of claim 7 , wherein coils respectively face first driving magnets in a direction of the second axis.

9. A camera module comprising:
the reflecting module of claim 1 ;
a lens module comprising a lens barrel including lenses; and
a driving portion configured to change a distance between the lens barrel and the reflecting module by moving the lens barrel.

10. The camera module of claim 9 , further comprising a second housing accommodating the lens barrel.

11. The camera module of claim 10 , wherein ball members configured to guide movement of the lens barrel are disposed between the lens barrel and the second housing.

12. The camera module of claim 11 , wherein guide grooves in which the ball members are disposed are formed on one or a combination of surfaces of facing surfaces of the lens barrel and the second housing, and the guide grooves are elongated in an optical axis direction of the lenses.

13. The camera module of claim 11 , wherein the driving portion comprises second driving magnets mounted on the lens barrel and coils disposed in the second housing to face the second driving magnets.

14. The camera module of claim 13 , wherein a second yoke is mounted in the second housing, the second yoke configured to attract the second driving magnets.

15. A reflecting module, comprising:
a holder in which a reflecting member configured to change a path of light and a magnet are mounted; and
a first housing,
wherein the holder is configured to rotate about a first axis and a second axis with respect to the first housing, and
wherein the holder is disposed on the first housing in a direction perpendicular to a direction of the first axis and a direction of the second axis.

16. The reflecting module of claim 15 , wherein magnetic force from the magnet supports the holder on the first housing in the direction perpendicular to the first axis direction and the second axis direction.

17. The reflecting module of claim 16 , wherein the holder is magnetically pulled toward the first housing in the direction perpendicular to the first and second axes.

18. The reflecting module of claim 16 , wherein a yoke is disposed on the first housing, and the magnet is disposed on a surface of the first holder facing the yoke in the direction perpendicular to the first and second axes.

19. The reflecting module of claim 18 , wherein the yoke is one or more of a magnetic material and a magnet.

20. The reflecting module of claim 15 , wherein the path of light is changed from a direction of the second axis to the direction perpendicular to the first and second axes.

21. The reflecting module of claim 15 , wherein first driving magnets are mounted in the holder, and coils, respectively facing the driving magnets, are disposed in the first housing.

22. The reflecting module of claim 21 , wherein coils respectively face driving magnets in a direction of the first axis.

23. The reflecting module of claim 22 , wherein coils respectively face driving magnets in a direction of the second axis.

24. A camera module comprising:
the reflecting module of claim 15 ;
a lens module comprising a lens barrel including lenses, and
a driving portion configured to change a distance between the lens barrel and the reflecting module by moving the lens barrel.

25. The camera module of claim 24 , further comprising a second housing accommodating the lens barrel.

26. A reflector configured to direct incident light toward a lens module of an imaging component in an apparatus, the reflector comprising:
a reflecting member configured to change a path of incident light;
a holder in which the reflecting member is disposed; and
a housing supporting the holder, wherein the holder is configured to rotate the reflecting member, the rotation with respect to a first axis and a second axis,
wherein the housing supports the holder on a surface facing the holder in a direction perpendicular to the first and second axes.

27. The reflector of claim 26 , wherein the holder is configured to be pressed by magnetic attraction toward the housing in the direction perpendicular to the first and second axes.

28. The reflector of claim 27 , further comprising a yoke disposed on the surface facing the holder and a first magnet disposed in the holder along the direction perpendicular to the first and second axes from the yoke.

29. The reflector of claim 28 , wherein the yoke is a second magnet.

30. The reflector of claim 29 , wherein the yoke and the first magnet are configured to magnetically attract each other to press the holder toward the housing in the direction perpendicular to the first and second axes.

31. The reflector of claim 27 , further comprising driving magnets disposed in the holder; and
coils, respectively facing the driving magnets, disposed in the housing,
wherein the coils and driving magnets drive the holder to rotate the reflecting member about the first axis and the second axis.
