Patent number: 9645347Abstract: A lens spacer may be configured to maintain a gap between a first lens and a second lens arranged along an optical axis. The lens spacer may include a first film member having a ring shape and may include a plurality of first tabs and a plurality of first recesses disposed between adjacent ones of the first tabs. The first tabs may protrude from an inner circumferential surface of the first film member toward the optical axis. A second film member may have a ring shape and may include a plurality of second tabs and a plurality of second recesses between adjacent ones of the second tabs. The second tabs may protrude from an inner circumferential surface of the second film member toward the optical axis. The first and second film members may be arranged along the optical axis, and the second tabs may overlap respective ones of the first recesses.Type: GrantFiled: November 25, 2015Date of Patent: May 9, 2017Assignee: Samsung Electronics Co., Ltd.Inventors: Masaaki Miyano, Young-ho Yu, Jung-ho Bae

Patent number: 9519139Abstract: 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.Type: GrantFiled: December 19, 2013Date of Patent: December 13, 2016Assignee: Samsung Electronics Co., Ltd.Inventors: Cheong-soo Park, Jong-jun Kim, Douk-young Song, Won-chul Cho, Jung-ho Bae, Young-ho Yu, Hee-yun Chung, Ki-yun Jo
