CAMERA LENS DOOR OPENING AND SHUTTING APPARATUS

摘要

PURPOSE: An apparatus for opening and shutting a camera lens door is provided to make the thickness thereof thin by opening and shutting a camera door through the contraction of a shape memory alloy. CONSTITUTION: A first shape memory allow is placed at the different position from a rotation center of a rotation door(130), and is contracted when a current is applied. Through the first shape memory alloy, the rotation door is rotated in an opening direction of the opening portion(111). A second shape memory alloy(242) is connected to the position different from the central portion of the rotation door. When current is applied, the second shape memory alloy is contracted. Through the first shape memory alloy, the rotation door is rotated in a closing direction, and a magnetic part(170) fixes the rotation door through a magnetic force.
