LENS DRIVING DEVICE AND CAMERA MODULE
FIG9 is a cross-sectional view of the first lens driving device according to the present embodiment
In the present embodiment, the center axis (refer to C1 in FIG9) of the lens coupled to the bobbin 1210 may be eccentrically disposed toward the direction of the dummy member 1330 from the center axis of the first lens driving device 1000. The center axis C1 of the bobbin 1210 may be disposed eccentrically toward the direction of the dummy member 1330 from the center axis C2 of the housing 1310. At this time, the center axis C1 of the lens can coincide with the center axis C1 of the bobbin 1210 or the center axis of the hole 1311 of the housing 1310. The center axis C2 of the first lens driving device 1000 and the center axis C2 of the housing 1310 may coincide with each other. At this time, the center axis C2 of the housing 1310 may be a center axis viewed with reference to the outer periphery of the housing 1310, not the center axis of the hole 1311 of the housing 1310. Further, the hole 1411a may be disposed eccentrically to the first surface side of the first lens driving device 1000. Through the above-mentioned structure of the present embodiment, a space can be secured so that the length L1 of the first coil unit 1422a in the lengthwise direction can be formed to be longer than the length L2 of each of the second and third coil units 1422b and 1422c in the lengthwise direction.
