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:

1. A camera module, comprising:
a lens module comprising lenses; and
a reflecting module disposed in front of the lens module and configured to change a path of light to direct light incident on the reflecting module toward the lens module,
wherein the reflecting module comprises
a holder in which a reflecting member configured to change the path of light is mounted and
a first housing supporting the holder, wherein 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,
wherein the holder is configured to be pressed toward the first housing, and
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.

2. The camera module of claim 1 , wherein a convex portion protruding in a direction in which the holder is pressed is disposed on one surface of facing surfaces of the holder and the first housing, and a concave portion formed to be concave in the direction in which the holder is pressed is disposed on the other surface.

3. The camera module of claim 2 , wherein the convex portion comprises support protrusions, and the concave portion comprises support grooves.

4. The camera module of claim 3 , wherein the support grooves comprise an inclined surface, and the support protrusions are configured to be in point contact with the inclined surface of the support grooves.

5. The camera module of claim 4 , wherein the support protrusions are configured to slide along the inclined surface of the support grooves, thereby enabling rotation of the holder.

6. The camera module of claim 2 , wherein the convex portion is disposed to be spaced apart from the concave portion, and a support portion is disposed between the convex portion and the concave portion.

7. The camera module of claim 6 , wherein each of the convex portion and the concave portion comprises inclined surfaces, and the support portion is disposed between respective inclined surfaces of the convex portion and inclined surfaces of the concave portion.

8. The camera module of claim 7 , wherein the support portion comprises ball members, and a center point of the reflecting member is formed in a meeting position at which extended lines of conceptual lines connecting a contact point between the ball members and the inclined surface of the convex portion meet a contact point between the ball members and the inclined surface of the concave portion.

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

10. The camera module of claim 1 , wherein the lens module further comprises:
a lens barrel including the lenses;
a carrier including the lens barrel mounted in the carrier; a second housing accommodating the carrier; and
a driving circuit configured to change a distance between the carrier and the reflecting module by moving the carrier.

11. The camera module of claim 10 , wherein ball members configured to guide movement of the carrier are disposed between the carrier 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 carrier and the second housing, and the guide grooves are elongated in an optical axis direction of the lenses.

13. The camera module of claim 10 , wherein the driving circuit comprises magnets mounted in the carrier and coils disposed in the second housing to face the magnets, and a second yoke is mounted in the second housing, the second yoke configured to attract the magnets.

14. A camera module, comprising:
a lens module including lenses; and
a reflecting module disposed in front of the lens module and configured to change a path of light to direct the light toward the lens module,
wherein the reflecting module comprises
a holder in which a reflecting member configured to change the path of light is mounted and includes a first housing supporting the holder, and
the holder is configured to slide with respect to the first housing, in order for the reflecting member to enable rotation with respect to a first axis and a second axis, and wherein the lens module comprises
a lens barrel having the lenses and including a second housing accommodating the lens barrel;
the lens barrel is configured to be pressed toward the second housing; and
the lens barrel is configured to slide in a direction different from a direction in which the lens barrel is pressed.

15. 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 slide with respect to the housing to rotate the reflecting member, the rotation with respect to a first axis and a second axis,
wherein a yoke is disposed on one surface of facing surfaces of the holder and the housing, and a magnet is disposed on the other surface, and wherein the yoke and the magnet are configured to magnetically attract each other to press the holder toward the housing.

16. The reflector of claim 15 , wherein the holder further comprises a protrusion and the housing further comprises a recess, wherein the protrusion and the recess are shaped to enable the sliding configuration.

17. The reflector of claim 16 , wherein the protrusion and the recess are each circular, triangular, rectangular, or polygonal.

18. The reflector of claim 16 , wherein support bearings are disposed between the protrusion and the recess to enable the sliding configuration.

19. An apparatus comprising:
an outer housing configured to house components of the apparatus; and
a first camera module disposed inside the outer housing, the first camera module configured to image light incident on the apparatus on an axis perpendicular to an axis of incidence to the outer housing, the first camera module further comprising
a lens module including lenses;
a reflecting member configured to change a path of incident light at a 90° angle;
a holder in which the reflecting member is disposed; and
an inner housing supporting the holder, wherein the holder is configured to slide with respect to the inner housing to rotate the reflecting member, the rotation with respect to a first axis and a second axis,
wherein a yoke is disposed on one surface of facing surfaces of the holder and the inner housing, and a magnet is disposed on the other surface, and wherein the yoke and the magnet are configured to magnetically attract each other to press the holder toward the inner housing.

20. The apparatus of claim 19 , wherein the axis of incidence is a thickness direction of the apparatus, and the axis perpendicular to the axis of incidence is a width direction or a length direction.

21. The apparatus of claim 19 , wherein the camera module further comprises:
a second camera module, wherein the second camera module is configured to image light incident on an axis of incidence.
