摘要：
A blade drive device includes: a blade; a drive source that drives the blade; and a chassis that has an opening opened and closed by the blade and that houses the blade and the drive source. The drive source includes: a rotor that is rotatably supported; a stator around which a coil for excitation is wound and which applies a rotational force to the rotor. The stator is arranged to surround a periphery of the opening and has a rectangular shape.
