摘要： A control device for control an actuator comprises a ‘shape-memory alloy that recovers to prescribed memory dimensions’ and ‘a force application means that applies an external force to the shape-memory alloy and changes its dimensions’ has a pre-heating means that, prior to the control of a driven member by the actuator, pre-heats the shape-memory alloy to a temperature at which the shape-memory alloy begins to change its shape or to a slightly lower temperature relative thereto.

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： An auto focus camera includes a usual zoom lens and provides a pseudo focal length mode, in which the size of focus condition detecting area, to the photographing scene to be printed, is variable. A pseudo focal length is stored and a focus condition is detected in accordance with a ray of light passed through the zoom lens. When the camera is in such a mode as to continuously detect focus condition for keeping an object in focus, or to be operated when the contrast of the object whose focus condition is detected is low, the focal length of the zoom lens and the pseudo focal length are controlled respectively in accordance with the mode.

摘要： A shake correction mechanism 1 has an elastic support member 2 for elastically and oscillatingly supporting a lens barrel 10 at one point, and first and second actuators 3a and 3b for applying oscillating forces to the lens barrel 10. When a moment is applied to the lens barrel 10 by the first and second actuators 3a and 3b, the elastic support member 2 is subjected to elastic deformation. Thereby, the lens barrel 10 is oscillated to tilt the optical axis thereof in a desires direction. Thus, the lens barrel 10 is oscillatingly driven without use of a rotary joint or the like as employed in the conventional gimbal mechanism. This arrangement enables to miniaturize the shake correction mechanism.
