Title:
LENS-DRIVING DEVICE
Document Type and Number:
Japanese Patent JP2011102887
Kind Code:
A
Abstract:

To propose the concrete composition of a lens-driving device which drives a lens in the optical axial direction and corrects blurring.

The lens-driving device 1 includes a first holing body 4, which holds the lens 2 and moves it in an optical axial direction (Z-direction); a second holding body 5 which holds the first holding body 4 so that the first holding body 4 is movable in the Z-direction; a fixing body which holds the second holding body 5 so that the second holding body 5 can move, in a direction which substantially orthogonally crosses the Z-direction; a first driving mechanism 7 for driving the first holding body in the Z-direction; a second driving mechanism 8 for driving the second holding body 5 in an X-direction; a third driving mechanism 9 for driving the second holding body 5 in a Y-direction; and a support member 13 for connecting the second holding body with the fixing body. The support member 13 is formed with an elastic material, and the second holding body 5 is supported by the fixing body so that the second holding body is movable, in a direction which substantially orthogonally crosses the Z-direction by the support member 13.
