Abstract

The present embodiment relates to a camera device comprising a first camera device, a second camera device, and a third camera device disposed between the first camera device and the second camera device, wherein: the first camera device includes a first bobbin, a first coil disposed on the first bobbin, a first magnet facing the first coil, and a second coil disposed under the first magnet; the second camera device includes a second bobbin, a third coil disposed on the second bobbin, and a second magnet facing the third coil; the third camera device includes a third bobbin, a fourth coil disposed on the third bobbin, a third magnet facing the fourth coil, a fourth magnet disposed on the third bobbin, and a Hall sensor for sensing the fourth magnet; and the Hall sensor of the third camera device is disposed between the fourth magnet of the third camera device and the second camera device.

First claim

The invention claimed is:

1. A camera device comprising:
a first camera device and a second camera device,
wherein the first camera device comprises a first cover, and a first magnet disposed in the first cover,
wherein the second camera device comprises a second cover, and a second magnet disposed in the second cover,
wherein the first magnet comprises four magnets disposed at positions corresponding to four corners of the first cover, respectively,
wherein the second cover comprises second-third and second-fourth lateral plates opposite to each other,
wherein the second magnet comprises a second-first magnet disposed on the second-third lateral plate, and a second-second magnet disposed on the second-fourth lateral plate, and
wherein the second cover is larger than the first cover when viewed from above.

2. The camera device of claim 1 , wherein the second cover comprises second-first and second-second lateral plates opposite to each other,
wherein the second camera device comprises a substrate and a capacitor,
wherein at least a portion of the substrate is disposed on the second-first lateral plate, and
wherein the capacitor is disposed on the substrate.

3. The camera device of claim 2 , wherein the second camera device comprises a second bobbin disposed in the second cover, a sensing magnet disposed on the second bobbin, and a Hall sensor configured to sense the sensing magnet, and
wherein the Hall sensor is disposed between the sensing magnet and the second-first lateral plate.

4. The camera device of claim 3 , wherein the substrate comprises an inner lateral surface facing the second bobbin, and
wherein the Hall sensor and the capacitor are disposed on the inner lateral surface of the substrate.

5. The camera device of claim 3 , wherein the sensing magnet of the second camera device is overlapped with the first magnet of the first camera device in a direction from a second optical axis of the second camera device to a first optical axis of the first camera device.

6. The camera device of claim 1 , wherein, when viewed from above, a shortest distance between a second optical axis of the second camera device and the second magnet is different from a shortest distance between a first optical axis of the first camera device and the first magnet.

7. The camera device of claim 1 , wherein the first camera device comprises a first bobbin disposed in the first cover, and a first coil disposed on the first bobbin, and
wherein the second camera device comprises a second bobbin disposed in the second cover, and a second coil disposed on the second bobbin.

8. The camera device of claim 2 , wherein the first cover comprises first-first and first-second lateral plates opposite to each other, and first-third and first-fourth lateral plates opposite to each other,
wherein the first-first lateral plate faces the second-second lateral plate.

9. The camera device of claim 1 , comprising a third camera device,
wherein the second camera device is disposed between the first camera device and the third camera device.

10. The camera device of claim 9 , wherein the third camera device comprises a third cover, a third bobbin disposed in the third cover, a third coil disposed on the third bobbin, and a third magnet facing the third coil,
wherein the third cover comprises third-first and third-second lateral plates opposite to each other, and third-third and third-fourth lateral plates opposite to each other;
wherein the third-first lateral plate faces the second-first lateral plate, and
wherein the third magnet comprises a third-first magnet disposed between the third coil and the third-third lateral plate, and a third-second magnet disposed between the third coil and the third-fourth lateral plate.

11. The camera device of claim 10 , wherein a distance between the third-first magnet and the third-first lateral plate is shorter than a distance between the third-first magnet and the third-second lateral plate.

12. The camera device of claim 11 , wherein a distance between the third-second magnet and the third-second lateral plate is shorter than a distance between the third-second magnet and the third-first lateral plate.

13. The camera device of claim 10 , wherein the first cover is larger than the third cover when viewed from above.

14. The camera device of claim 3 , wherein the second camera device comprises a compensation magnet disposed on the second bobbin, and
wherein the compensation magnet is symmetrical to the sensing magnet about a second optical axis of the second camera device.

15. The camera device of claim 1 , wherein the first camera device comprises a first base and a fourth coil disposed on the first base, and
wherein the fourth coil is configured to move the first magnet in a direction perpendicular to a first optical axis of the first camera device.

16. The camera device of claim 7 , wherein the second coil is longer than the first coil when viewed from above.

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

18. A camera device comprising:
a first camera device and a second camera device,
wherein the first camera device comprises a first cover, a first bobbin disposed in the first cover, a first coil disposed on the first bobbin, and a first magnet facing the first coil,
wherein the second camera device comprises a second cover, a second bobbin disposed in the second cover, a second coil disposed on the second bobbin, and a second magnet facing the second coil,
wherein the first magnet comprises four magnets disposed at positions corresponding to four corners of the first cover, respectively,
wherein the second cover comprises second-third and second-fourth lateral plates opposite to each other,
wherein the second magnet comprises a second-first magnet disposed between the second-third lateral plate and the second bobbin, and a second-second magnet disposed between the second-fourth lateral plate and the second bobbin, and
wherein the second coil is longer than the first coil when viewed from above.
