摘要: A lens driving device includes a movable system having a lens frame to which a lens is fixed, and a fixation system including a guide shaft inserted into a guide hole formed in the lens frame to allow the lens frame to advance and retract in an optical axis direction and a restricting member for restricting rotation of the lens frame about the guide shaft. A lead screw is rotatable with respect to the fixation system about its axis which extends substantially parallel to the guide shaft, and the lead screw is threadedly fitted to the movable system. A motor rotates the lead screw to allow the movable system to advance and retract along the lead screw. A biasing spring is arranged substantially parallel to the guide shaft and biases the lens frame in both the axial direction and a direction orthogonal to the axial direction.

摘要: Provided is a lens driving device, including: a movable system including a lens frame to which the lens is fixed; a fixation system including a guide shaft inserted into a guide hole formed in the lens frame to allow the lens frame to advance and retract in an optical axis direction and a restricting member for restricting rotation of lens frame about the guide shaft; a lead screw, which is a substantially-shaft-like member rotatable with respect to the fixation system about an axis thereof substantially parallel to the guide shaft, and in which a male thread threadably fitted to the movable system is formed; a motor for rotating the lead screw about the axis thereof to allow the movable system to advance and retract along the lead screw; and a biasing member arranged in substantially parallel to the guide shaft, for biasing the lens frame in the axial direction and about an axis thereof. Thus, a lens driving device which are capable of performing accurate position adjustment of the lens frame in the optical axis direction with the small number of components without causing decentering about the lens frame to which the lens is fixed, and an electronic device provided with the lens driving device are provided.

摘要: A lens driving device has a motor mounted to a plate, a lead screw connected to the motor for undergoing rotation about an axial line thereof, a nut threadingly engaged with the lead screw, and a casing mounted to the plate for housing the lead screw and the nut. The nut has a convex protruding portion protruding outwardly from an outer peripheral surface of the nut. The casing has a fitting groove linearly formed in the casing in a direction of the axial line for receiving the protruding portion in a state in which the protruding portion is fitted in the fitting groove so as to regulate rotation of the nut, and for movably guiding the protruding portion in the fitted state in the direction of the axial line to move the nut back and forth along the lead screw. At least one of the casing and the protruding portion of the nut has a tapered surface formed so as to forcibly guide the protruding portion toward the fitting groove to gradually fit the protruding portion into the fitting groove when the casing and the plate are mounted together.

摘要: A drive module includes a drive unit having a cylindrical supporting member, a driven member accommodated inside the supporting member, and a driving unit configured to reciprocally move the driven member along the axial direction of the supporting member. A top-covered cylindrical cover is attached to the drive unit and covers the drive unit. The cover includes a metallic exterior packaging member configured to cover at least an outer periphery of the drive unit to shield the drive unit from external electromagnetic fields, and a resin spacer attached to the exterior packaging member, the spacer having engaging portions engageable with the drive unit to achieve positioning of the cover.
