Image blur correction device, imaging lens unit, and camera unit |
摘要 |
An image blur correction device includes: a tabular base (100) having an opening portion (101) opened in an optical axis direction; a tabular movable holding member (110) configured to hold a lens and supported to be movable within a plane vertical to an optical axis of the lens; a first drive mechanism (130) including a first magnet and a first coil so as to drive the movable holding member in a first direction vertical to the optical axis; a second drive mechanism (140) including a second magnet and a second coil so as to drive the movable holding member in a second direction vertical to the optical axis; and a detecting device (170, 180) for detecting a position of the movable holding member. The first drive mechanism and the second drive mechanism are arranged at positions that are line-symmetric with respect to a first straight line (S1) perpendicular to the optical axis of the lens. |
