ータ駆動のシヤツタ羽根開閉装置。 It consists of a rotor that can rotate around a support shaft and is magnetized in the radial direction, a plurality of stators that have a plurality of magnetic poles facing the outer periphery of the rotor, and a coil that excites the stator, and can rotate in forward and reverse directions. It has a step motor, shutter blades that form an aperture aperture, a spring that biases the blades in the closing direction, and a regulating portion that restricts the operating range of the blades in the closing direction, and when the coil is not energized, the shutter blades are closed. Against the tendency of the rotor to remain in a static stable position where the rotor stops due to the magnetic coupling force between the magnetic poles of the rotor and the magnetic poles of the stator, the regulation is performed in accordance with the position where the blades are stopped by being biased by the spring. Shutter blade opening/closing device driven by a step motor.
