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： An ultrasonic drive apparatus for preventing a slip between an object to be driven and a driving part of the apparatus to drive the object. The driving part includes an elastic member through which vibrations from electrical-mechanical converters are transmitted to the object. The elastic member can deform in a direction in which the object is driven. The driving part makes a predetermined locus to drive the object while the elastic member deforms in the direction so as to absorb the slip between the object and the driving part. The elastic member and the converters are mounted symmetrically relative to an axis which is generally perpendicular to the direction in which the object is driven, so that the object can be driven forward and backward.

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.
