An optical image stabilizer includes a base member, a movable member that is disposed at the base member and moves along a plane orthogonal to an optical axis, a movable-member driving portion that is disposed at the base member and the movable member, and moves the movable member in a direction orthogonal to the optical axis, and a regulator that regulates a movement of the movable member along the plane orthogonal to the optical axis. The regulator regulates the movement of the movable member with two movement paths, which are a linear movement path along which the movable member moves in a direction orthogonal to the optical axis and a rotation path along which the movable member rotates around a point on the linear movement path.

Optical image stabilizer and lens driving apparatus

In a lens driving device, magnetic attraction plates that are magnetic bodies are disposed on a fixed frame at both ends of a movement region of a movable unit. Therefore, when the movable unit moves in the fixed frame to one side or to the other side in the fixed frame and reaches a position at either end of the fixed frame, magnets on the movable unit are magnetically attracted to the magnetic attraction plates on the fixed frame continuously. As a result, the movable unit can be retained at the position even when the coil becomes de-energized.
