摘要： A storing section (70) stores a second initial contact instruction value, which is predefined as an instruction value for positioning a movable portion (5) to a second contact position where the movable portion (5) is contacted with a stopper (8), and an initial standby instruction value, which is predefined as an instruction value for positioning the movable portion (5) to a specified standby position within a moving range of the movable portion (5). A correcting section (42) calculates an actual standby instruction value by correcting the initial standby instruction value, based on a second actual contact instruction value obtained when a contact detection section (41) has detected that the movable portion (5) is positioned to the second contact position, and the second initial contact instruction value. A setting section (43) sets a standby position corresponding to the actual standby instruction value, as an actual standby position of the movable portion (5).

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 base plate, a first slider and a second slider are fit in one another to produce one assemblage. The first slider is caused to move relative to the base plate along an X axis by a first actuator. The second slider moves in unison with the first slider, and also is caused to solely move along a Y axis by a second actuator. A magnetic sensor unit is provided in the base plate, and a magnet support is provided in the second slider so as to face the magnetic sensor unit. A magnet is disposed on a lower face of the magnet support. The magnetic sensor unit and the magnet form a position detection mechanism, and the second slider in which the magnet is disposed requires no electric wiring.

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.
