Abstract

The present invention relates to a camera lens door opening/closing device which automatically opens and closes a camera door installed in a cell phone or other device using shape memory alloy that shrinks when current is applied. The present invention, the camera lens door opening/closing device for automatically uncovering and covering a camera lens, comprises: a base positioned on the front of the lens, wherein an opening is formed; a rotary door which has one end hinge-coupled with the base and opens/closes the opening; a first shape memory alloy which is connected to the rotary door and uncovers the opening by shrinking due to the application of current and rotating the rotary door; an elastic unit which is coupled with the rotary door and applies elasticity to the rotary door in the direction for covering the opening; and a locking part which fixes the rotary door when the opening is uncovered.
