Title:
IMAGING LENS UNIT AND IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/029671
Kind Code:
A1
Abstract:
An imaging lens unit having an imaging lens (4) for focusing light from an object
onto an imaging surface, a lens holder (3) for holding the imaging lens (4), a holder
(2) for holding the lens holder (3) so that it can move along the optical axis of
the imaging lens (4) and that it can rotate in the direction tilted relative to
the optical axis, a magnet (5) and coil (6) for causing drive forces to act independently
to the lens holder (3), the drive forces acting in the direction along the optical
axis to at least three positions on the outer periphery of the lens holder (3),
a Hall element (7) for detecting the attitude of the lens holder (3) relative to
the optical axis, and a control device for controlling the magnitude and direction
of drive force of each coil (6). In the imaging lens unit, movement in the optical
direction of and tilt movement relative to the optical axis of the imaging lens
can be performed by a simple structure.
