Lens driving device and camera module comprising same
A lens driving device according to an embodiment of the present invention comprises: a first lens; and an optical path-changing member that changes the path of light incident from the first lens and emits same, wherein the first lens and the optical path-changing member are arranged so as to be tilted simultaneously with respect to a first axis and to be tilted separately with respect to a second axis.
1 . A lens driving device comprising:
a first lens;
an optical path changing member configured to change a path of light incident from the first lens and emit the light;
a lens holder on which the first lens is disposed; and
a support member on which the lens holder is disposed,
wherein the first lens and the optical path changing member are disposed to be simultaneously tilted about a first axis,
wherein the first lens and the optical path changing member are disposed to be individually tilted about a second axis,
wherein the lens holder and the optical path changing member are disposed to be supported by the support member and
wherein the support member includes a plurality of first support portions disposed to be spaced apart from each other in a direction toward the second axis.
2 . The lens driving device of claim 1 ,
wherein the lens holder is supported by the support member.
3 . The lens driving device of claim 2 , comprising an optical path changing member holder on which the optical path changing member is disposed,
wherein the optical path changing member is supported by the support member.
4 . The lens driving device of claim 1 ,
wherein the lens holder and the optical path changing member are simultaneously supported by the plurality of first support portions.
5 . The lens driving device of claim 4 , comprising a frame on which a plurality of coils and the support member are disposed,
wherein the support member includes a second support portion supported by the frame to be tilted about the first axis, and
the second support portion is provided as a single support portion extending along the second axis or a plurality of support portions disposed along the second axis.
6 . The lens driving device of claim 5 , comprising:
a first magnet disposed on the support member;
a second magnet disposed on the optical path changing member holder; and
a third magnet disposed on the lens holder,
wherein the plurality of coils include first to third coils respectively corresponding to the first to third magnets.
7 . The lens driving device of claim 5 , wherein a side surface of the lens holder is disposed to be spaced a predetermined distance from a corresponding side surface of the frame.
8 . The lens driving device of claim 7 , wherein the predetermined distance is in a range of 0.2 to 1.0 mm.
9 . The lens driving device of claim 5 , wherein a lower surface of the support member is disposed to be spaced a predetermined distance from a corresponding one surface of the frame.
10 . The lens driving device of claim 1 , wherein the lens holder and the optical path changing member are individually tiltable about the first axis.
11 . A lens driving device comprising:
a first lens;
an optical path changing member configured to change a path of light incident from the first lens and emit the light;
a lens holder on which the first lens is disposed; and
a support member on which the lens holder is disposed,
wherein the first lens and the optical path changing member are disposed to be simultaneously tilted about a first axis, and
wherein the first lens and the optical path changing member are disposed to be individually tilted about a second axis,
wherein the lens holder and the optical path changing member are disposed to be supported by the support member to be individually tilted about the first axis,
wherein the lens holder and the optical path changing member are simultaneously supported by the plurality of first support portions.
