Patent ID: 8412033

Claim:
An image blur correction device comprising: a substantially tabular base having an opening portion; a substantially tabular movable holding member that is configured to hold a lens and supported to be movable within a plane perpendicular to an optical axis of the lens; a first drive mechanism including a first magnet and a first coil so as to drive the movable holding member in a first direction perpendicular to the optical axis; a second drive mechanism including a second magnet and a second coil so as to drive the movable holding member in a second direction perpendicular to the optical axis; and a detecting means for detecting a position of the movable holding member, wherein the movable holding member is movably supported to be adjacent to the base, the first drive mechanism and the second drive mechanism are arranged at positions that are line-symmetric with respect to a first straight line perpendicular to the optical axis of the lens, each of the first coil and the second coil is formed into a substantially elliptic annular shape having a major axis and a minor axis and arranged in such a manner that each center is laced on a second straight line perpendicular to the optical axis of the lens and the first straight line, the major axis of the first coil is arranged on a third straight line running through a magnetized boundary face of the first magnet, the major axis of the second coil is arranged on a fourth straight line running through a magnetized boundary face of the second magnet, the third straight line and the fourth straight line are arranged to form a predetermined inclination angle with respect to the second straight line, and the detecting means includes a first position sensor that is arranged on the major axis of the first coil and detects a magnetic change by relatively moving with respect to the first magnet, and a second position sensor that is arranged on the major axis of the second coil and detects a magnetic change by relatively moving with respect to the second magnet.
