Title
(EN) COMPACT CAMERA ACTUATOR CAPABLE OF MOVING A LENS HOLDER USING THE BENDING OF POLYMER
(KO) 소형 카메라 엑츄에이터
Abstract
(EN)
PURPOSE: A compact camera actuator is provided to return a raised lens holder using relative interaction between a magnetic material and a magnet without a spring. CONSTITUTION: A compact camera actuator comprises a housing(410), a lens holder(420), a driving unit(440), a magnetic material, and a magnet(470). A lens(430) is installed inside the lens holder, and the lens holder is installed in the housing and allowed to move up and down. The driving unit is installed in the housing and transfers the lens holder upward when power is applied. The magnetic material is fixed to one of the lens holder and the housing while the magnet is fixed to the other one. The magnetic material and the magnet are arranged opposite to each other and provide the lens holder with a force for pulling down. COPYRIGHT KIPO 2012
