Conversely, when a reverse current is applied to the yawing coil (412), a force may be applied to the yawing coil (412) in the other direction opposite to the one direction due to the electromagnetic interaction between the yawing coil (412) and the yawing magnet (411).

[0171] In a camera device according to a modified example, as shown in FIG. 15, the yawing coil (412) may be formed to have a curvature corresponding to that of the yawing magnet (411). Furthermore, in a modified example, a yoke (630) may be additionally disposed to enhance the electromagnetic force between the yawing magnet (411) and the yawing coil (412) and between the pitching magnet (421) and the pitching coil (422). The yoke (630) may be disposed between two pitching magnets (421) and below the yawing magnet (411). The yoke (630) may be disposed on the pitching carrier (310).

[0172] In a camera device according to another variation, as shown in FIG. 16, the yawing coil (412a) may be formed in a square ring shape without curvature. The yawing coil (412a) may be formed flat without curvature. The yawing coil (412a) may be placed on a virtual plane. In other variations as well, a yoke (630) may be additionally placed to enhance the electromagnetic force between the previously described yawing magnet (411) and the yawing coil (412a) and between the pitching magnet (421) and the pitching coil (422).

[0173] In a camera device according to the first embodiment of the present invention, when current is applied to the pitching coil (422), an electromagnetic field is formed around the pitching coil (422), and the pitching magnet (421) can move relative to the pitching coil (422) by means of electromagnetic interaction between the pitching magnet (421) and the pitching coil (422). At this time, the pitching magnet (421) can be rotated or tilted around the y-axis (see pitch in FIG. 14). The pitching angle of the pitching magnet (421) can be plus or minus 3 degrees. When the pitching magnet (421) is rotated or tilted, the pitching carrier (310), the yawing carrier (210), and the camera module (700) can also be rotated or tilted together with the pitching magnet (421).

[0174] When a forward current is applied to the pitching coil (422), a force may be applied to the pitching magnet (421) in one direction due to the electromagnetic interaction between the pitching coil (422) and the pitching magnet (421). Conversely, when a reverse current is applied to the pitching coil (422), a force may be applied to the pitching magnet (421) in the opposite direction to the one direction due to the electromagnetic interaction between the pitching coil (422) and the pitching magnet (421). At this time, the forward current may be a current flowing upward in the inner end region of the yawing coil (412). Conversely, the reverse current may be a current flowing downward in the inner end region of the yawing coil (412).

[0175] In a camera device according to a modified example, the pitching coil (422) may be formed in a rounded shape as shown in FIG. 17. In the first embodiment of the present invention shown in FIG. 1, etc., the pitching coil (422) is formed in a shape close to a square ring, but in a modified example, the shape of the pitching coil (422) may be changed. The pitching coil (422) may be formed to have a curvature corresponding to that of the pitching magnet (421). The upper surface of the pitching coil (422) may have a curvature corresponding to that of the upper surface of the pitching magnet (421). The lower surface of the pitching coil (422) may have a curvature corresponding to that of the lower surface of the pitching magnet (421).

[0176] In the first embodiment of the present invention, when current is applied to the yawing coil (412) and the camera module (700) is driven in a yawing manner, the first part (711) of the substrate (710) can support the camera module (700) in a movable manner. Additionally, when current is applied to the pitching coil (422) and the camera module (700) is driven in a pitching manner, the second part (712) of the substrate (710) can support the camera module (700) in a movable manner. The third part (713) of the substrate (710) connects the first part (711) and the second part (712) and can support one or more of the yawing and pitching operations of the camera module (700). The first to third parts (711, 712, 713) of the substrate (710) are arranged to overlap multiple times so that the overlapping parts move away from or closer to each other, thereby supporting the movement of the camera module (700). Although the functions of the first to third parts (711, 712, 713) have been described separately above, during yawing operation, all of the first to third parts (711, 712, 713) can move to support the camera module (700). Similarly, during pitching operation, all of the first to third parts (711, 712, 713) can move to support the camera module (700).

[0245] Hereinafter, the operation of a camera device according to a second embodiment of the present invention will be described with reference to the drawings.

[0246] FIG. 32 is a drawing for explaining the yawing and pitching drives of a camera device according to a second embodiment of the present invention. FIG. 33 is a drawing for explaining the yawing drive of a camera device according to a second embodiment of the present invention. FIG. 34 is a drawing for explaining the pitching drive of a camera device according to a modified example. FIG. 35 (a) is a cross-sectional perspective view of a camera device according to a second embodiment of the present invention, and (b) is a perspective view of a flexible substrate of a camera module.

[0247] In a camera device according to the second embodiment of the present invention, when current is applied to the yawing coil (1420), an electromagnetic field is formed around the yawing coil (1420), and the driving magnet (1410) can move relative to the yawing coil (1420) by means of electromagnetic interaction between the driving magnet (1410) and the yawing coil (1420). At this time, the driving magnet (1410) can be rotated or tilted around the x-axis (see yaw in FIG. 32). The yawing angle of the driving magnet (1410) can be plus or minus 3 degrees. When the driving magnet (1410) is rotated or tilted, the yawing carrier (1210), pitching carrier (1310), and camera module (1700) can also be rotated or tilted together with the driving magnet (1410).

[0248] When a forward current is applied to the yawing coil (1420) (see current direction in FIG. 33), a force may be applied to the driving magnet (1410) in one direction due to the electromagnetic interaction between the yawing coil (1420) and the driving magnet (1410) (see Fy in FIG. 33). Conversely, when a reverse current is applied to the yawing coil (1420), a force may be applied to the driving magnet (1410) in the other direction opposite to the one direction due to the electromagnetic interaction between the yawing coil (1420) and the driving magnet (1410). In this case, the forward current may be a current flowing upward in the inner end region of the yawing coil (1420). Conversely, the reverse current may be a current flowing downward in the inner end region of the yawing coil (1420).

[0249] The yawing coil (1420) may be formed by two coils spaced apart from each other as shown in FIG. 33. Since the yawing coil (1420) is also positioned on the opposite side of the part shown in FIG. 33, it may be formed with a total of four coils. The two coils may be formed in corresponding shapes.

[0250] In a camera device according to the second embodiment of the present invention, when current is applied to the pitching coil (1430), an electromagnetic field is formed around the pitching coil (1430), and the pitching coil (1430) can move relative to the driving magnet (1410) by means of electromagnetic interaction between the driving magnet (1410) and the pitching coil (1430). At this time, the pitching coil (1430) can be rotated or tilted around the y-axis (see pitch in FIG. 32). The pitching angle of the pitching coil (1430) can be plus or minus 3 degrees. When the pitching coil (1430) is rotated or tilted, the pitching carrier (1310) and the camera module (1700) can also be rotated or tilted together with the pitching coil (1430).

[0251] When a forward current is applied to the pitching coil (1430) (see current direction in FIG. 34), a downward force may act on the left region of the pitching coil (1430) and an upward force may act on the right region of the pitching coil (1430) due to the electromagnetic interaction between the pitching coil (1430) and the driving magnet (1410) (see Fz in FIG. 34). Conversely, when a reverse current is applied to the pitching coil (1430), an upward force may act on the left region of the pitching coil (1430) and a downward force may act on the right region of the pitching coil (1430) due to the electromagnetic interaction between the pitching coil (1430) and the driving magnet (1410). At this time, the forward current may be a current flowing from the right region of the pitching coil (1430) to the left region. Conversely, the reverse current may be a current flowing from the left region to the right region of the pitching coil (1430).

[0252] In a modified example, the driving magnet (1410) may include a first magnet part (1411) and a second magnet part (1412). The driving magnet (1410) may include a first magnet part (1411) arranged parallel to the y-axis and a second magnet part (1412) arranged perpendicularly to the inner surface of the first magnet part (1411). That is, in the modified example, the second magnet part (1412) may be additionally arranged compared to the second embodiment of the present invention. In the modified example, the Lorentz force between the driving magnet (1410) and the pitching coil (1430) may be strengthened by the second magnet part (1412). Through this, the driving force in the pitch direction of the pitching coil (1430) may be improved. In the direction of the optical axis, the second magnet part (1412) may overlap with the pitching coil (1430). The second magnet part (1412) may be formed in a pentagonal shape when viewed from the side. The second magnet part (1412) may be positioned below the pitching coil (1430). The second magnet part (1412) may be positioned to be in contact with the first magnet part (1411).

[0253] In the second embodiment of the present invention, when current is applied to the yawing coil (1420) and the camera module (1700) is driven in a yawing manner, the third part (1713) of the substrate (1710) can support the camera module (1700) movably (see yaw in FIG. 35 (a)). Additionally, when current is applied to the pitching coil (1430) and the camera module (1700) is driven in a pitching manner, the first part (1711) of the substrate (1710) can support the camera module (1700) movably. The third part (1713) of the substrate (1710) connects the first part (1711) and the second part (1712) and can support one or more of the yawing and pitching drives of the camera module (1700). The first to third portions (1711, 1712, 1713) of the substrate (1710) are arranged to overlap multiple times so that the overlapping portions move away from or closer to each other, thereby supporting the movement of the camera module (1700).
