摘要： An art of a driving device for appropriately improving a response of an SMA actuator will be provided. A portable telephone 1 has an image stabilization system 10 for driving an image pickup unit 9 by a pair of driving members 15a and 15b functioning as actuators, thereby performing image stabilization. Driving members 15a and 15b are formed as a wire of shape memory alloy (SMA) and when a voltage is applied to both ends and a current is supplied, driving force is generated in the contraction direction. With respect to the wire diameter of the SMAs, the wire diameter of the SMAs is set between 10 μm and 80 μm, thus the mountability and response are improved appropriately.

摘要： A lens-driver for driving a lens for compensating image blur caused by camera shaking has two driving-levers. In each driving-lever, one end is rotatably connected to a lens frame via a holding shaft and the other end is rotatably supported by a rotation shaft. Two driving levers are arranged generally on one straight line, and there is formed a generally perpendicular angle by a line connecting the holding shaft of one driving-lever and an optical center of the lens, and a line connecting the holding shaft of the other driving-lever and the optical center. Another lens-driver has two driving mechanisms. One driving mechanism drives the lens, and the other driving mechanism drives a shutter mechanism or an aperture mechanism. In the lens barrel, one mechanism occupies one half area and the other mechanism occupies the other half area.
