LENS BARRIER, BARREL ASSEMBLY INCLUDING THE LENS BARRIER, AND ELECTRONIC APPARATUS INCLUDING THE BARREL ASSEMBLY

摘要

A lens barrier is described. The lens barrier includes: a base having an open portion that provides an optical path; a plurality of blades that are rotatably mounted to the base so as to move between an opening position where the open portion is opened and a closing position where the open portion is closed; and a driving member that provides a driving force to the plurality of blades to rotate the plurality of blades. A forward guide, for moving the driving member forward along an optical axis such that the driving member approaches the plurality of blades, and a backward guide, for moving the driving member away from the plurality of blades when the plurality of blades is at the closing position, are formed at at least one of the driving member or the base.
