Abstract
A blade driving device in which a central axis is defined includes a plurality of blades, two coil groups and a magnet. The blades are arranged around the central axis. The two coil groups are arranged around the central axis, include at least two coils with the central axis direction as a winding axis and are separated in the central axis direction. The magnet is arranged between the two coil groups in such a manner that a magnetized surface faces the two coil groups. The coils and the magnet generate an electromagnetic force along a circumferential direction of a circle centered on the central axis to drive the blades.
