Thus, an optical actuator capable of reducing the size of a product is provided.

A sensor shifting module is provided. The sensor shifting module includes a fixed body; a first movable body movably disposed in the fixed body; a second movable body movably disposed on the first movable body and coupled to an image sensor having an imaging plane oriented in a first direction; and a first driver configured to move the first movable body in a direction orthogonal to the first direction with respect to the fixed body; a second driver configured to rotate the first movable body about an axis parallel to the first direction with respect to the fixed body; and a third driver configured to rotate the second movable body to rotate about an axis orthogonal to the first direction with respect to the first movable body.

A coil substrate according to an embodiment includes an insulating layer; a first coil pattern portion disposed on one surface of the insulating layer; a second coil pattern portion disposed on the other surface of the insulating layer; and a pad portion disposed on the one surface of the insulating layer and connected to the first coil pattern portion, wherein the first coil pattern portion includes: an inner coil pattern portion; and an outer coil pattern portion spaced apart from the inner coil pattern portion at a predetermined interval and disposed outside the inner coil pattern portion, wherein the pad portion is disposed between the inner coil pattern portion and the outer coil pattern portion.

An optical element driving device includes: a fixed portion; an optical element in which liquid is encapsulated between a first end surface and a second end surface opposite to each other and the first end surface is fixed to the fixed portion; a first movable portion supported by the fixed portion and rotatable around an axis of a first rotation shaft; and a second movable portion supported by the first movable portion, rotatable around an axis of a second rotation shaft orthogonal to the first rotation shaft, and fixing the second end surface.

Actuators for rotating or tilting an optical element, for example an optical path folding element, comprising a voice coil motor (VCM) and a curved ball-guided mechanism operative to create a rotation or tilt movement of the optical element around a rotation axis upon actuation by the VCM. In some embodiments, an actuator includes two, first and second VCMs, and two curved ball-guided mechanisms operative to create rotation or tilt around respective first and second rotation axes.

A sensor shifting module includes a fixed body; a movable body movably, disposed in the fixed body, comprising an image sensor having an imaging plane oriented in a first direction; a substrate configured to deform based on a movement of the movable body with respect to the fixed body; and a driver, configured to move the movable body in a direction orthogonal to the first direction, comprising a driving coil coupled to one of the fixed body and the movable body, and a driving yoke coupled to another of the fixed body and the movable body. The driving yoke is disposed to oppose the driving coil in the direction orthogonal to the first direction. When current is applied to the driving coil, the movable body is configured to move in the direction orthogonal to the first direction by electromagnetic interaction between the driving coil and the driving yoke.

A camera module is provided. The camera module includes a lens barrel configured to accommodate a lens; a barrel holder coupled to the lens barrel; a driving device configured to drive the barrel holder; and a first reinforcing member integrated with the barrel holder, and configured to support a driving magnet of the driving device, wherein the first reinforcing member includes a body portion disposed to oppose the driving magnet and extending in a length direction of the driving magnet; a first protrusion which extends from a first end of the body portion in a direction opposing a driving coil of the driving device; and a second protrusion which extends from a second end of the body portion in a direction opposite to an extending direction of the first protrusion.
