    摘要： A device according to the present invention includes at least one first light amount adjustment blade moving rectilinearly in a direction crossing a light passage direction and at least one second light amount adjustment blade pivoting within a plane crossing the light passage direction. When a light passage aperture of a polygonal shape formed by annularly superposing the first light amount adjustment blade and the second light amount adjustment blade is enlarged, a shape of the light passage aperture comes close to a circular shape from a polygonal shape.
