Abstract

The present embodiment relates to a dual camera module comprising a first camera module and a second camera module, wherein: a first magnet unit of the first camera module includes a first magnet and a second magnet, both disposed opposite to each other on a side surface of a first housing; a second magnet unit of the second camera module includes a third to a sixth magnet arranged on four respective corners of a second housing; a third magnet unit is disposed on a side surface of the first housing facing the second housing; the third magnet unit is disposed between the first magnet and the second magnet; and the third magnet unit is smaller than the first magnet and is disposed on a virtual line connecting an optical axis of the first camera module and an optical axis of the second camera module.

First claim

The invention claimed is:

1. A camera device comprising:
a first camera module comprising a first cover member, a first bobbin disposed in the first cover member, and a first magnet unit disposed between the first cover member and the first bobbin;
a second camera module comprising a second cover member, a second bobbin disposed in the second cover member, and a second magnet unit disposed between the second cover member and the second bobbin; and
a second shield member formed as a metal,
wherein the first cover member comprises a first lateral plate facing the second cover member, a second lateral plate opposite to the first lateral plate, and third and fourth lateral plates opposite to each other,
wherein the first magnet unit comprises a first magnet disposed between the third lateral plate of the first cover member and the first bobbin, and a second magnet disposed between the fourth lateral plate of the first cover member and the first bobbin,
wherein the second magnet unit comprises third to sixth magnets disposed on four corner areas of the second cover member, respectively, and
wherein the second shield member is disposed outside the second lateral plate of the first cover member.

2. The camera device of claim 1 , comprising a first shield member formed as a metal,
wherein the first shield member is disposed on the first lateral plate of the first cover member.

3. The camera device of claim 1 , comprising third and fourth shield members formed as a metal,
wherein the third shield member is disposed outside the third lateral plate of the first cover member, and
wherein the fourth shield member is disposed outside the fourth lateral plate of the first cover member.

4. The camera device of claim 3 , wherein the second shield member and the third shield are connected, and
wherein the second shield member and the fourth shield member are connected.

5. The camera device of claim 3 , wherein the third shield member is a flat plate shape and is disposed to contact with the third lateral plate of the first cover member, and
wherein the fourth shield member is a flat plate shape and is disposed to contact with the fourth lateral plate of the first cover member.

6. The camera device of claim 1 , wherein the second shield member is formed as a magnetic substance.

7. The camera device of claim 1 , wherein the second shield member is a flat plate shape and is disposed to contact with the second lateral plate of the first cover member.

8. The camera device of claim 1 , wherein the first and second magnets are symmetrical based on an optical axis, and
wherein each of the first and second magnets has a flat plate shape.

9. The camera device of claim 1 , wherein the third to sixth magnets are symmetrical based on an optical axis, and
wherein each of the third to sixth magnets has a pillar shape with an inner lateral surface greater than an outer lateral surface.

10. The camera device of claim 1 , wherein the first camera module comprises a first housing disposed between the first cover member and the first bobbin, and
wherein the first and second magnets are disposed on the first housing.

11. The camera device of claim 1 , wherein the second camera module comprises a second housing disposed between the second cover member and the second bobbin, and
wherein the third to sixth magnets are disposed on the second housing.

12. The camera device of claim 1 , wherein the first camera module comprises a first coil disposed on the first bobbin, and
wherein the second camera module comprises a second coil disposed on the second bobbin.

13. The camera device of claim 1 , wherein the second camera module comprises a base coupled with the second cover member, and a third coil disposed on the base and configured to electromagnetically interact with the second magnet unit, and
wherein the second bobbin is configured to be moved in a direction perpendicular to an optical axis or tilted by an electromagnetic interaction between the second magnet unit and the third coil.

14. The camera device of claim 1 , wherein the second cover member comprises a fifth lateral plate facing the first cover member, and
wherein a discrete distance between the first lateral plate and the fifth lateral plate is within 4 mm.

15. The camera device of claim 1 , wherein each of the first and second cover members is formed as a non-magnetic substance.

16. The camera device of claim 1 , wherein a size of the second cover member is different from a size of the first cover member.

17. An optical apparatus comprising:
a main body;
the camera device of claim 1 disposed on the main body; and
a display part disposed on the main body and outputting an image photographed by the camera device.

18. A camera device comprising:
a first camera module comprising a first cover member, and a first magnet unit disposed in the first cover member;
a second camera module comprising a second cover member, and a second magnet unit disposed in the second cover member; and
a second shield member formed as a metal,
wherein the first cover member comprises a first lateral plate facing the second cover member, a second lateral plate opposite to the first lateral plate, and third and fourth lateral plates opposite to each other,
wherein the first magnet unit comprises first and second magnets overlapped with each other in a direction from the third lateral plate to the fourth lateral plate,
wherein the second magnet unit comprises third to sixth magnets disposed on four corner areas of the second cover member, respectively, and
wherein the second shield member is disposed outside the second lateral plate of the first cover member.

19. The camera device of claim 18 , comprising a first shield member formed as a metal,
wherein the first shield member is disposed on the first lateral plate of the first cover member.

20. The camera device of claim 18 , comprising third and fourth shield members formed as a metal,
wherein the third shield member is disposed outside the third lateral plate of the first cover member, and
wherein the fourth shield member is disposed outside the fourth lateral plate of the first cover member.
