摘要： An optical anti-shake resilient support mechanism, an anti-shake driving device, a lens driving fitting, an imaging equipment and an electronic apparatus are provided. The optical anti-shake resilient support mechanism includes two X-direction resilient sheets symmetrically distributed with an optical axis of an optical component as an axis of symmetry and used to connect a focusing motor assembly and an optical anti-shake frame or to connect a base and the optical anti-shake frame; and two Y-direction resilient sheets symmetrically distributed with the optical axis of the optical component as an axis of symmetry and used to connect the base and the optical anti-shake frame or to connect the focusing motor assembly and the optical anti-shake frame. The unidirectional translation is one of X-axis unidirectional translation and Y-axis unidirectional translation, unidirectional performance is better than that of other optical anti-shake mechanisms, which can greatly simplify production process and reduce cost.

摘要： According to an embodiment, a blade driving device in which a central axis is defined includes a plurality of blades and a plurality of groups. The blades are arranged around the central axis. Each of the groups has a magnet and at least two coils and the groups are arranged at intervals along a circumference of a circle centered on the central axis. A winding axis direction of the coil coincides with a normal direction of a facing surface of the magnet facing the coil, magnetic poles formed on the facing surface are reversed at a position corresponding to a center of the coil when viewed from the winding axis direction, and each of the groups generates an electromagnetic force along a circumference direction of the circle to drive the blades.
