Abstract: An optical member driving device is described that includes a base, an FPC, a lower crimp plate, an upper crimp plate and a plurality of SMA wires. The FPC is fixed on the base. The lower crimp plate is fixed on the FPC. The upper crimp plate slides on the lower crimp plate. The plurality of SMA wires are fixed to the lower crimp plate and the upper crimp plate at both ends. The lower crimp plate includes a plurality of plate pieces having one crimp portion, and each of the plate pieces is fixed on the FPC in a state of being separated from each other and is electrically connected to the FPC.

Abstract: An actuator is disclosed that includes a lens driving device, a movable portion, a holder, a supporting plate spring, and a plurality of suspension wires. The lens driving device has a driving mechanism for driving a lens body forward and backward in an optical axis direction and is fixed to a case. The movable portion is arranged on a rear side of the lens driving device together with an image sensor. The holder is fixed to the case and surrounding the lens driving device from outside. The supporting plate spring is fixed to a front surface of the holder. The plurality of suspension wires couple the supporting plate spring and the movable portion.

Abstract: An actuator is disclosed having a sensor substrate, a coil substrate and an FPC. The sensor substrate includes an image sensor on a front surface thereof. The coil substrate includes a coil for driving the image sensor and is provided with a first through hole. The FPC includes a main body portion and a coupling portion extending from a periphery of the main body portion and is coupled to an outside element. The main body portion is provided with a second through hole. The sensor substrate is fixed to the main body portion from a rear side, the coil substrate is fixed to the main body portion from a front side, and the image sensor is exposed to a front surface through the first through hole and the second through hole.

Abstract: An actuator is disclosed having a fixed portion and a movable portion for mounting a rectangular image sensor. The movable portion includes a rectangular image sensor, coils and position sensors. The coils are arranged at positions corresponding to respective sides of the image sensor, and one pair of opposing two sides are respectively provided with two coils juxtaposed along each side. When the two coils arranged at positions right opposite each other corresponding to the opposing two sides are set as one set of coils, one position sensor is provided corresponding to each set of coils, and the position sensor is arranged at a position corresponding to one coil in each set of coils.
