Abstract
The present invention relates to an image photographing device, and is invented to absorb vibration of the plate spring when the lens holder is moved, thereby stabilizing rapidly the lens holder. According to one example, the small camera provided with a damper includes a lens holder provided with lens and driven in an optical axial direction, a fixing unit housing the lens holder, a plate spring which is arranged to the upper part or lower part of the lens holder and connects the lens holder to the fixing unit and supports it so that the lens holder is moved in an optical axial direction, a driving unit for driving the lens holder in an optical axial direction, a support unit arranged on the lower parts of the lens holder and the fixing unit, and a damper member attached to the plate spring for absorbing vibrations of the plate spring wherein the damper member is made with polymer chemical having an elastic force and the elastic force of the damper member is smaller than that of the plate spring.
