Abstract
A disclosed aperture module includes a base defining an opening; a rotation plate seated on the base and rotatable about an optical axis, and including rotation plate teeth disposed along an inner circumferential surface; an aperture driving portion coupled to the rotation plate to rotate the rotation plate in response to an input of an electrical signal; and a plurality of blades stacked in two stages and disposed inside the rotation plate, each blade including blade teeth to engage the rotation plate teeth. The blades move in conjunction with rotation of the rotation plate to define an incidence hole of variable size, and the plurality of blades are disposed to partially overlap neighboring blades of the other stage without overlapping with neighboring blades of the same stage.
