Patent Description:
As the spread of various portable terminals is widely generalized and wireless Internet services are commercialized, the demands of consumers related to portable terminals are also diversifying, so that various types of additional devices are being installed in the portable terminals.

Among them, there is a camera module for photographing a subject as a photograph or a moving picture. Meanwhile, a camera device in recent years has been applied with a hand-shake correction function that prevents an image from being shaken due to hand-shake of a photographer.

As one of the methods for performing the hand-shake correction function, there is a module tilt method. In a conventional camera device of a module tilt method, electrical signals of about <NUM> or more image sensors are connected to a fixing unit through a printed circuit board (PCB) to move the image sensors.

However, in this case, there is a problem in that the movement of the movable part is restricted, and the resistance (load) to the movement of the movable part is also large. In addition, since the dispersion of the modulus of elasticity is large due to the dispersion of Young's modulus of the raw material inside the PCB and the PCB processing tolerance, additional work is required to reduce the performance dispersion.

In particular, since the rigidity in the radial direction is high due to the PCB structure, the resistance to rotational driving is high, and therefore, the aforementioned structure has a problem in that it is difficult to be applied for compensation in the rolling direction, that is, compensation for rotational shaking.

<CIT> discloses a swing fulcrum comprising a first plate part in which a hole is formed, an elastic member made of an elastomer arranged so as to be superposed on the first plate part on a rear side in the optical axis direction, and a second plate part arranged so as to be superposed on the elastic member on a rear side in the optical axis direction are provided in a part facing a rear end part of the movable body in a solid body. <CIT> discloses a camera driving apparatus including: a camera section with an imaging plane; a movable unit which houses the camera section inside and includes an attracting magnet and a convex partial sphere on its outer surface; a fixed unit which has a depressed portion in which a magnetic body and the movable unit are loosely fit, which brings the convex partial sphere of the movable unit into a point or line contact with the depressed portion under magnetic attractive force of the attracting magnet to the magnetic body, and which allows the movable unit to rotate freely on the spherical centroid of the first convex partial sphere; a panning driving section; a tilting driving section; a rolling driving section; a camera driving section which shifts an image sensor two-dimensionally in a plane that intersects with the optical axis at right angles and which rotates the image sensor on the optical axis; a first detector which detects the tilt angles of the camera section in the panning and tilting directions; a second detector which detects the angle of rotation of the camera section that is rotating in the rolling direction; and a third detector which detects the magnitudes of shift of the image sensor along the panning rotation axis and the tilting rotation axis. <CIT> discloses an optical unit with shake correction function including: a movable member; a swing supporting mechanism supporting the movable member such that the movable member is able to swing; and a fixation member supporting the movable member via the swing supporting mechanism.
