特徴とするモータ駆動の羽根作動装置。 A motor that can rotate in forward and reverse directions based on control signals from an electronic circuit, and a gear that is rotationally driven by this motor.
A first blade having an external tooth portion that meshes with the gear and rotates forward and backward around a first fixed shaft provided at a position substantially opposite to the gear with the shutter opening interposed therebetween, and a first blade that meshes with the gear. Rotates in the opposite direction to the first blade around a second fixed shaft having an internal toothed portion and provided in a direction opposite to the first blade and located at a position substantially opposite to the gear with the shutter opening sandwiched therebetween. A second blade is provided which opens and closes the shutter opening together with the first blade, and the meshing portion of the internal toothed portion and the external toothed portion with respect to the gear has a difference in distance from the center of the shutter opening. 1. A motor-driven blade actuating device characterized by comprising means for correcting substantially equal changes in opening area formed by each blade at the center of the shutter opening of the first and second blades.
