摘要： A lens driving device, a camera device, and an electronic apparatus are provided in which variation is not liable to occur in a friction coefficient of a guide mechanism. A lens driving device 12 includes a guide mechanism 38 configured to guide movement of a lens. The guide mechanism 38 includes a first member formed with guide projections 44, 48 and a second member conned with guide grooves 46, 50 in which the guide projections slide. At least one out of the first member or the second member is configured from a resin composition resulting from mixing a liquid crystal polymer together with a fluororesin. A fluororesin layer is provided to at least one surface of the guide projections or the guide grooves formed to at least the first member or the second member configured from the resin composition.

摘要： A lens driving device, a camera device, and an electronic apparatus are provided that include a base not susceptible to thermal deformation. A lens driving device includes a movable body including a lens support body, and a base configured to support the movable body so as to be able to move in an optical axis direction of a lens. The base includes a base body formed from a resin and having a rectangular plate shape when viewed along the optical axis direction of the lens, and a ring shaped metal member embedded in the base body. The metal member is formed with a projecting portion facing outward at each side of a rectangular shape and exposed from the base body.

摘要： An optical member driving device is provided that includes a fixed portion with an accommodation space for a lens device, and a movable portion, which has a holding portion for holding an image sensor, and is rockably supported at a position on a rear side of the lens device. The movable portion includes an FPC having a main body portion connected to the image sensor and a connecting portion for connecting the main body portion and an external device and a coil substrate which is fixed on a front surface of the main body portion of the FPC and on which a coil is formed. The connecting portion has a base end portion which rises from a predetermined position on an edge of the main body portion to a front side. The base end portion is opposed to a side surface of the coil substrate with an adhesive interposed.

摘要： A lens driving device is disclosed that includes a first mover, a second mover and plate springs. The first mover is provided with a first through hole for accommodating a first lens body with an optical axis in a Z direction, and includes a pair of first plate-like magnets arranged parallel to each other at positions across the first through hole. The second mover is provided with a second through hole for accommodating a second lens body with an optical axis in the Z direction, and includes a pair of second plate-like magnets arranged parallel to each other at positions across the second through hole. The plate springs respectively support the first mover and the second mover movably in the Z direction. The first mover and the second mover are arranged side by side in a direction orthogonal to the Z direction.

摘要： An aperture switching device is described that includes a base, a casing fitted to cover the base, and clamping parts fixed to the base. The clamping parts are driving power source input terminals and a shape memory alloy wire with two ends electrically connects the clamping parts. The base has a first light transmission hole, a rotary connecting part, a sliding groove, and a position regulating part. The casing has a second light transmission hole that corresponds to the first light transmission hole. A movable bump is connected to the shape memory alloy wire and slidably disposed within the sliding groove. An elastic member is disposed between the position regulating part and the movable bump. An optical aperture switching unit is positioned with one end portion mounted on the rotary connecting part and the end portion includes a switching slot mounted on the movable bump.
