A lens driving apparatus includes a lens barrel, a carrier configured to accommodate the lens barrel, a focusing unit configured to move the carrier in an optical axis direction, and an image stabilizer unit configured to move the lens barrel in the carrier in a direction perpendicular to the optical axis direction, wherein the image stabilizer unit includes a lens holder to which the lens barrel is fixed, and a frame includes a body supporting the lens holder to guide movement of the lens barrel and having a side portion forming an outer rim, and a reinforcing member coupled to the side portion of the body, wherein the side portion extends along the outer rim of the frame, while the reinforcing member has a step portion formed in a cross-section perpendicular to the extending direction of the side portion.

A lens driving device is disclosed that includes two movers, a long quadrangular frame body, at least two coils and an FPC. The movers are arranged side by side and provided with a through hole for accommodating a lens body, respectively. The frame body surrounds an outer periphery of the two movers. The two coils face one mover of the two movers and are fixed to two long sides of the frame body. The FPC includes coil connecting terminals electrically connected to the two coils.

An optical sensing system is provided, including a sensing module, a light emitter, and a light receiver. The sensing module has a substrate, an optical waveguide disposed on the substrate, and a sensing membrane disposed on the optical waveguide for carrying a specimen. The light emitter emits a sensing light to the optical waveguide, and the light receiver receives the sensing light that propagates through the optical waveguide.

An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed part, a movable part, a driving assembly, and a positioning assembly. The movable part is movably disposed on the fixed part. The movable part is connected to an optical element. At least a portion of the driving assembly is disposed on the fixed part. The positioning assembly is disposed on the fixed part or the movable part to limit the movable part at an extreme position relative to the fixed part.

The present embodiment relates to a lens driving device comprising: a housing; a bobbin disposed inside the housing so as to move in a first direction; a first coil disposed on the outer circumferential surface of the bobbin; a magnet disposed in the housing; a base disposed below the housing; a coil part having a second coil disposed between the housing and the base so as to face the magnet; a substrate disposed between the housing and the base; and a conducting member for electrically connecting the coil part to the substrate, wherein the conducting member is disposed at a corner of the base.

Provided are a lens barrel and an imaging device, with which it is possible to lock an optical member of which the movement in an optical axis direction is made free in a case where there is no electrification, particularly to hold the optical member in a locked state without use of electric power. A movable frame that holds a focus lens is driven in the optical axis direction by a linear motor. In a case where the movable frame is to be locked with the linear motor being not electrified, the movable frame (engagement portion) is caused to abut onto a restriction portion at an end portion of the movable range of the movable frame and a locking ring is caused to rotationally move to a locking position by an electric actuator. Accordingly, the movable frame is fixed by the restriction portion and a locking portion of the locking ring to become unable to move. The electric actuator includes a worm gear as a power transmission mechanism and it is possible to hold the locking ring at the locking position by means of an irreversible rotation function of the worm gear.

An optical unit with a shake correction function includes a gimbal mechanism swingably supporting a movable body and including a connection mechanism including a spherical body and a support part contacted with the spherical body. The movable body includes a holding part holding a gimbal frame receiving member including a plate part fixed with the spherical body and a pair of protruded parts protruded to the support part side. The holding part is formed in a cut-out recessed part including a rear wall face, a pair of side wall faces, and a bottom wall face. When viewed in the optical axis direction, a pair of the protruded parts overlaps the support part. The movable body includes a facing wall part facing a pair of the protruded parts, and a separated distance between the facing wall part and the protruded parts is narrower than a thickness of the support part.

A camera module includes a housing, a lens module accommodated in the housing, a first optical image stabilization (OIS) driving unit configured to move the lens module, relative to the housing, in a first direction perpendicular to an optical axis direction, and a second OIS driving unit configured to move the lens module, relative to the housing, in a second direction perpendicular to the optical axis direction and intersecting the first direction, wherein the first OIS driving unit includes first voice coil motors disposed on both sides of the lens module in the first direction, and the second OIS driving unit includes second voice coil motors disposed on both sides of the lens module in the first direction.
