Abstract
An aperture stop includes: a housing; blades disposed on an object-side surface of the housing to move in a direction perpendicular to an optical axis direction to form a light incident hole having a variable size; and driving bars to move in conjunction with the blades and to rotate with respect to a rotational axis parallel to an optical axis to drive the blades. The blades include a first blade and a second blade moving in opposite directions to each other with respect to the optical axis.

An aperture stop comprising:
- a housing;
- blades disposed on an object-side surface of the housing and configured to move in a direction perpendicular to an optical axis direction to form a light incident hole having a variable size;
- and
- driving bars configured to move in conjunction with the blades, and to rotate with respect to a rotational axis parallel to an optical axis to drive the blades,
- wherein the blades include a first blade and a second blade configured to move opposite to each other with respect to the optical axis.

An aperture stop comprising:
- a housing;
- a rotational axis disposed in an edge region of the housing and extended in a direction parallel to an optical axis direction;
- driving bars connected to the rotational axis and configured to rotate about the rotational axis;
- and
- blades, each blade connected to one of the driving bars, comprising a through hole, and configured to move in a direction perpendicular to the optical axis direction based on rotation of the rotational axis to form a light incident hole having a variable size.
