Figure 9 , Figure 14b and Figure 14c As shown, the first protrusion 1320 can be tilted about the x-axis (first axis) while being inserted into the groove 1121 of the housing 1100.

[0108] The rotating plate 1300 may include a second protrusion 1330. The second protrusion 1330 may protrude from a second surface located on the opposite side of the first surface of the base 1310. The second protrusion 1330 may have a hemispherical shape. The second protrusion 1330 may be formed when a portion of the rotating plate 1300 is bent. At this time, a groove corresponding to the second protrusion 1330 may be formed on the opposite side of the second protrusion 1330.

[0109] The second protruding portion 1330 may include multiple second protruding portions. The second protruding portion 1330 may include a second-1 protruding portion 1331 and a second-2 protruding portion 1332.

[0110] In a modified embodiment, the rotating plate 1300 may include a groove replacing at least one of the first protrusion 1320 and the second protrusion 1330. In this case, the first camera device 1000 may include a ball formed separately from the rotating plate 1300 and disposed in the groove of the rotating plate 1300.

[0111] The first camera device 1000 may include a first drive unit 1400. The first drive unit 1400 can rotate the mover 1200 about a first axis.

[0113] The first magnet 1410 may include multiple magnets. The first magnet 1410 may include two first magnets. The first magnet 1410 may include a first side magnet 1411 disposed on one side surface of the two side surfaces of the mover 1200 and a second side magnet 1412 disposed on the other side surface of the two side surfaces of the mover 1200.

The first coil 1420 may include a first-1 coil 1421 and a first-2 coil 1422. The first-1 coil 1421 may face a first-side magnet 1411. The first-2 coil 1422 may face a second-side magnet 1412. The first-1 coil 1421 and the first-2 coil 1422 may be electrically disconnected, allowing them to be controlled individually. Alternatively, the first-1 coil 1421 and the first-2 coil 1422 may be electrically connected.

[0117] However, in a modified embodiment, the first coil 1420 may be disposed in the mover 1200 and the first magnet 1410 may be disposed in the housing 1100.

The second coil 1520 may electromagnetically interact with the second magnet 1510. Figure 13b and Figure 13c As shown, the second coil 1520 can be used to tilt the mover 1200 about the y-axis. When current is applied to the second coil 1520, the mover 1200 can rotate relative to the second protrusion 1330 of the rotating plate 1300. Figure 13b As shown, when current is applied to the second coil 1520 in the first direction, the mover 1200 can rotate to one side about the second protrusion 1330 of the rotating plate 1300 (see reference). Figure 13b a) in the text. Furthermore, as in... Figure 13c As shown, when current is applied to the second coil 1520 in a second direction opposite to the first direction, the mover 1200 can rotate around the second protrusion 1330 of the rotating plate 1300 to the other side (see reference). Figure 13c (d)

[0122] However, in the modified embodiment, the second coil 1520 may be disposed in the mover 1200, and the second magnet 1510 may be disposed in the housing 1100.

[0123] The first camera device 1000 may include a Hall sensor 1530. The Hall sensor 1530 may be disposed in a substrate 1650. The Hall sensor 1530 may be disposed inside a second coil 1520. The Hall sensor 1530 can detect a second magnet 1510. The Hall sensor 1530 can detect the magnetic force of the second magnet 1510. The Hall sensor 1530 can be used to provide feedback on the actuation of the mover 1200. The Hall sensor 1530 may include multiple Hall sensors.

[0124] The first camera device 1000 may include a first yoke 1610. The first yoke 1610 may be disposed on one surface of the second magnet 1510.

Figure 10 The length of L2 in the middle can be greater than that of the second magnet 1510 (see reference). Figure 10The length of L1 in the second axis direction is longer. As a modified implementation, in the second axial direction, the length of the first yoke 1610 can be the same as the length of the second magnet 1510. In the second axial direction, the length of the first yoke 1610 (refer to...) Figure 10 L2 in the figure can be equal to the distance between the first side magnet 1411 and the second side magnet 1412. The first yoke 1610 can connect two second yokes 1621 and 1622. However, as a modified embodiment, the first yoke 1610 can be spaced apart from the second yoke 1620. The first yoke 1610 can be formed as a separate component from the second yoke 1620. However, as a modified embodiment, the first yoke 1610 and the second yoke 1620 can be integrally formed. The first yoke 1610 can be formed from SPC or SUS 4 series materials. When formed from SPC, anti-oxidation electroplating is required, while when formed from SUS 4 series materials, electroplating may be unnecessary.

[0125] The length of the first yoke 1610 in the direction of the second axis can be 1 to 2 times the length of the second magnet 1510. The length of the first yoke 1610 in the direction of the second axis can be 1.2 to 1.6 times the length of the second magnet 1510.

The length of the first yoke 1610 in the direction of the second axis can be approximately 1.4 times the length of the second magnet 1510.

[0126] In this embodiment, the yoke can be attached to the prism actuator of the first camera device 1000 to increase the electromagnetic force and reduce the magnetic flux leakage to the outside. The attachment location of the yoke can be the surface of a magnet or the surface of a coil. According to this embodiment, when the yoke is absent, the leakage magnetic flux at the contrast surface can be reduced by more than two times. When using a multi-camera device, in the case of an AF module, the second camera device located on one side of the first camera device 1000 uses two magnet structures, while in the case of an OIS module, three magnet structures can be used. The yoke can be formed as large as possible to minimize the leakage magnetic flux along the y-axis of the yoke. The first yoke 1610 can be formed with a shape and size corresponding to the first groove 1211 of the mover 1200.

[0127] The first camera device 1000 may include a second yoke 1620. The second yoke 1620 may be disposed on one surface of the first magnet 1410. Alternatively, as a modified embodiment, the second yoke 1620 may be disposed on a side surface of the first coil 1420.

The second yoke 1620 may be connected to the first yoke 1610. The second yoke 1620 may be disposed between the first magnet 1410 and the support 1210. The second yoke 1620 may be formed in a shape corresponding to the shape of the first magnet 1410. The second yoke 1620 may be formed from SPC or SUS 4 series materials. When formed from SPC, anti-oxidation electroplating is required, while when formed from SUS 4 series, electroplating may be unnecessary.

[0128] The second yoke 1620 may include multiple second yokes. The second yoke 1620 may include two second yokes 1621 and 1622.

The third magnet 1630 may be disposed on a second surface of the mover 1200. The third magnet 1630 may be fixed to the mover 1200 by an adhesive. The term "third" in the third magnet 1630 is used to distinguish it from other magnets, and the third magnet 1630 may be referred to as a "fourth magnet," etc.

[0130] The first camera device 1000 may include a fourth magnet 1640. The fourth magnet 1640 may be disposed in the housing 1100 such that the attractive force acts together with the third magnet 1630. The fourth magnet 1640 may be disposed on a side wall portion 1120 of the housing 1100. As a modified embodiment, the fourth magnet 1640 may be disposed in a second cover member 1670. The fourth magnet 1640 may include a second surface facing the first surface of the third magnet 1630. The second surface of the fourth magnet 1640 may have a different polarity than the first surface of the third magnet 1630. Thus, an attractive force can act between the third magnet 1630 and the fourth magnet 1640. The mover 1200 can press the rotating plate 1300 against the side wall portion 1120 of the housing 1100 by the force of the third magnet 1630 being pulled toward the fourth magnet 1640. Therefore, even when the mover 1200 moves, the mover 1200, the rotating plate 1300, and the housing 1100 can maintain contact. The "fourth" in the fourth magnet 1640 is to distinguish it from other magnets, and the fourth magnet 1640 can be referred to as the "fifth magnet," etc. The fourth and fifth magnets can be "magnets used for attraction."
