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.

摘要： Drive technology is provided which makes suitable low velocity driving and smooth changing of driving velocity possible and achieves reduced power consumption. In the driving device, the drive unit is driven which engages with drive shaft which moves back and forth in tandem with extension and contraction of the piezoelectric element. In this driving device, when the output cycle for cycle Te is repeated such that the voltages applied to the piezoelectric element 11 are the maximum value (+Vp), the minimum value (−Vp), and the middle value (0V), the movement velocity of the drive unit 13 can be changed by thinning the output cycle at cycle Tf. As a result, suitable low velocity driving can be carried out and power consumption can be reduced in the drive unit.

摘要： To provide an image shake correcting optical apparatus using a small, lightweight engaging mechanism for the correction lens holder engaging mechanism. A ring-shaped engaging member 16 formed of shape memory alloy and having three engaging arms on its inside is located outside a lens holder 11 for a correction lens L3, and the engaging contacts 16b at the tips of the engaging arms 16a are pushed toward the center of the ring-shaped engaging member by means of coil springs 17. The engaging member 16 formed of shape memory alloy has a prescribed memorized shape so that the arms 16a will assume a retracted position, and where no heat is applied, the engaging contacts 16b of the engaging arms press onto the lens holder 11 for the correction lens L3 from the outside due to the spring force of the coil springs 17, and engages with and maintains in place the lens holder 11. Where heat is applied, the engaging arms 16a retract, whereupon the engagement of the lens holder 11 is terminated.
