Abstract:
A zoom lens barrel assembly includes: a first zoom ring comprising a first protrusion; a guide ring disposed around the first zoom ring comprising a first guide slot through which the first protrusion passes, and a second guide slot; a second zoom ring comprising a second protrusion, and movable in an axial direction; a first cylinder comprising a guide groove into which the second protrusion inserts, and a third protrusion passing through the second guide slot, and disposed between the first and second zoom rings; a second cylinder disposed around the guide ring comprising a fourth protrusion, a first groove portion into which the first protrusion inserts, and a second groove portion into which the third protrusion inserts, and supporting the first zoom ring and the first cylinder; and an external cylinder disposed around the second cylinder and comprising a third groove portion into which the fourth protrusion inserts.
Abstract:
A zoom lens barrel assembly includes a first barrel, a second barrel, a lens barrier, and a transparent member. The first barrel supports at least one lens. The second barrel surrounds at least a portion of an outer surface of the first barrel, and supports the first barrel to protrude along an optical axis direction. The lens barrier is disposed on a front side of the first barrel, and is moved in a direction that intersects an optical axis to expose the at least one lens when the first barrel is protruded. The transparent member is disposed on a front side of the lens barrier, and prevents impurities from entering the first barrel.

Abstract:
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.
