摘要： Provided are a lens driving device, a camera module, and a camera-mounted device for which the miniaturization and weight reduction can be achieved and the reliability can also be improved. The lens driving device includes AF and shake-correcting driving parts utilizing a voice coil motor. An AF fixing part includes an AF control part controlling the energization current through an AF coil part. The AF driving part includes upper and lower elastic supporting parts, auto-focusing power-source lines connected to power-supplying suspension wires functioning as a shake-correcting supporting part, signal lines connected to signal suspension wires functioning as a shake-correcting supporting part, and coil power-supply lines electrically connecting the AF control part to the AF coil part. The upper elastic supporting part functions at least as the AF power-supply lines or the signal lines, and the lower elastic supporting part functions as the coil power-supply lines.

摘要： A camera module includes a holder provided with a lens unit and displaceable along an optical axis direction of the lens unit; a coil formed from a wound wire having both end portions serving as lead wires, and provided on the holder; a yoke and magnets for providing a magnetic field to the coil; a flexible printed circuit board for supplying an electrical current to the lead wires; and upper and lower leaf springs for supporting the holder so that the holder is displaceable along the optical axis direction. Each of the upper and lower springs includes an outer annular portion, an inner annular portion provided inside the outer annular portion and attached to one of the cylindrical end portions of the holder, and a plurality of bridge portions coupled between the outer annular portion and the inner annular portion. The flexible printed circuit board is arranged below the lower leaf spring, and a part of the insulating sheet portion thereof is formed into a tongue part which extends in a tongue-shaped manner so that the tongue part is arranged in a space between a predetermined bridge portion of the lower leaf spring and the lead wires. The provision of such a tongue part makes it possible to prevent the bridge portion from making contact with the lead wires even in the event that the bridge portion is hardly deformed.

摘要： An autofocus actuator is provided by which it is possible to easily confirm that a holder and a yoke do not make contact with each other even when the space between the holder and the yoke is made as small as possible in order to improve shock resistance. The autofocus actuator includes light transmission holes for confirming a space between an inner peripheral surface of an inner cylindrical portion of the yoke and an outer peripheral surface of a cylindrical portion of the holder provided with a lens unit and being capable of adjusting its position in the optical axis direction by supplying electrical power to a coil secured to the holder. The light transmission holes are provided at predetermined positions of a flange portion of the holder and a stopper for attaching a leaf spring to the holder, respectively, so that light can pass therethrough.
