摘要:
This invention provides an electromagnetically driven device applicable to a lens driving device with an anti-shake function by a simple structure that enables the movable member to swing around an axis thereof. A flat spring for swinging connects to a stationary frame body provided with a permanent magnet set and a coil set for swinging is mounted on an outer circumference of a movable frame body. When an axial direction of the movable frame body is designated as the Z axis, the coil set for swinging including a first through fourth coils arranged around the Z axis and spaced at uniform intervals with each winding around an axis perpendicular to the Z axis and opposite to the permanent magnet set respectively. The permanent magnet set includes a first through fourth magnets, wherein each magnet is arranged between two adjacent coils among the first through fourth coils.
