Description

[0001] Cross-reference to related applications

[0002] This application claims the benefit of priority to Korean Patent Application No. 10-2024-0150101, filed on October 29, 2024, with the Korean Intellectual Property Office, and Korean Patent Application No. 10-2025-0142978, filed on September 30, 2025, the entire disclosure of which is incorporated herein by reference for all purposes. Technical Field

[0003] This disclosure relates to a reflection module and a camera module including the reflection module. Background Technology

[0004] Recent mobile devices may include camera modules that bend the path of light by placing a reflective element in front of a lens module.

[0005] Additionally, the camera module can perform image stabilization to compensate for camera shake during image capture and improve resolution. This image stabilization can be achieved through a two-axis rotation of the reflective element.

[0006] In this case, because the reflective element can be set to a rotatable state, it may tilt to one side when the camera module is off.

[0007] In addition, the biaxial rotation of the reflective element may require multiple drivers, and the structure of multiple drivers may be complex, which may lead to increased size and weight. Summary of the Invention

[0058] One or more examples involve a reflective module and a camera module that includes the reflective module, and the camera module can be mounted on a portable electronic device such as, but not limited to, a mobile communication terminal, a smartphone, or a tablet personal computer (PC).

[0059] One or more examples may provide a reflective module and a camera module including the reflective module, which is capable of positioning the reflective element in its initial position without the application of power.

[0060] Figure 1 A perspective view of an exemplary camera module according to one or more embodiments is shown. Figure 2 and Figure 3 This is a partial cross-sectional perspective view of an exemplary camera module according to one or more embodiments, and Figure 4 An exploded perspective view of an exemplary camera module according to one or more embodiments is shown.

[0061] Reference Figures 1 to 4 An exemplary camera module 1 according to one or more embodiments includes a reflection module 300 and a housing 100.

[0062] The reflection module 300 may be disposed within the housing 100 and includes a reflection member 310 having a reflective surface.

[0063] In an exemplary embodiment, the housing 100 is described as a separately configured component, i.e., not included within the reflective module 300. However, this is merely an example, and the housing 100 may also be configured as a component included within the reflective module 300. In this example, the reflective member 310, the guide member 320, and the support 330 may be disposed within the housing 100.

[0064] The reflector 310 can be configured to rotate about two different axes for jitter compensation. For example, the reflector 310 can rotate within the housing 100 about two axes that are perpendicular to each other.

[0065] In an exemplary embodiment, camera module 1 may further include a first lens module 210.

[0066] The first lens module 210 includes at least one lens, and the at least one lens has a first optical axis (Y-axis). The first optical axis (Y-axis) is based on Figure 4 It can extend in the vertical direction. The first optical axis (Y-axis) can pass through the center of at least one lens of the first lens module 210.

[0067] In an exemplary embodiment, the first lens module 210 includes a first lens barrel 211 and a first lens holder 212. At least one lens may be disposed in the first lens barrel 211, and the first lens barrel 211 may be connected to the first lens holder 212. The first lens holder 212 may be connected to the reflection module 300. Alternatively, the first lens module 210 may include only the first lens barrel 211 without the first lens holder 212, and the first lens barrel 211 may also be connected to the reflection module 300.

[0068] The first lens module 210 can be positioned in front of the reflection module 300. Here, "in front" can refer to the direction closest to the object, or based on the positive first optical axis (Y-axis) direction (+Y-axis direction) of the reflection module 300. For example, the first lens module 210 can be positioned above the reflection module 300 in the first optical axis (Y-axis) direction.

[0069] The first lens module 210 can be connected to the reflection module 300. For example, the first lens holder 212 of the first lens module 210 can be connected to the holder 330 of the reflection module 300.

[0070] The first lens module 210 and the reflection module 300 are disposed in the housing 100.

[0071] In an exemplary embodiment, the camera module 1 may further include a second lens module 220. The reflection module 300 is disposed between the first lens module 210 and the second lens module 220. The second lens module 220 may include a plurality of lenses and has a second optical axis (Z-axis). The plurality of lenses are arranged along the second optical axis (Z-axis). The second optical axis (Z-axis) may pass through the center of the plurality of lenses of the second lens module 220.

[0072] The first optical axis (Y-axis) of the first lens module 210 and the second optical axis (Z-axis) of the second lens module 220 can be formed to be perpendicular to each other.

[0073] The first lens module 210 includes one or more lenses, and the second lens module 220 includes multiple lenses.

[0074] When viewed along the first optical axis (Y-axis), one or more lenses of the first lens module 210 may be circular. When viewed along the second optical axis (Z-axis), at least one lens of the plurality of lenses of the second lens module 220 may be non-circular. For example, a non-circular lens may have different lengths in two directions perpendicular to the second optical axis (Z-axis) and to each other. In an exemplary embodiment, in a non-circular lens, its length in the first axis (X-axis) direction, which is perpendicular to both the first optical axis (Y-axis) and the second optical axis (Z-axis), is longer than its length in the first optical axis (Y-axis) direction.

[0075] The first lens module 210 and the reflection module 300 can be configured to rotate together for shake correction. The second lens module 220 can move in the direction of the second optical axis (Z-axis) for focus adjustment.

[0076] The camera module 1 may also include an image sensor module 800.

[0077] The image sensor module 800 includes a sensor housing, an image sensor, and a printed circuit board, and may also include an infrared cutoff filter.

[0078] An infrared cutoff filter can be mounted on the sensor housing. The infrared cutoff filter blocks light in the infrared region from passing through the second lens module 220.

[0079] The printed circuit board is connected to the sensor housing, and the image sensor is mounted on the printed circuit board.

[0080] The reinforcement plate used for rigidity enhancement can be mounted on the rear surface of the printed circuit board (e.g., the surface opposite to the surface on which the image sensor is mounted).

[0081] Connectors used for electrical connections to portable electronic devices can be located on printed circuit boards.

[0082] Light passing through the second lens module 220 is received by the image sensor module 800 (e.g., an image sensor).

[0083] The camera module 1 may also include a housing 110. The housing 110 is coupled to the housing 100 to cover the upper part of the housing 100. The housing 110 may include an opening, and the first lens module 210 may be disposed in the opening.

[0084] In the example, at least a portion of the first lens module 210 may be configured to protrude to the outside of the housing 100 and the outer casing 110.

[0085] Figure 5 An exploded perspective view of the reflective module and housing is shown. Figure 6 A bottom-view perspective view of the guide components of the reflection module is shown, and Figure 7 A partially exploded 3D view of the reflection module is shown.

[0086] in addition, Figure 8 A plan view of the guide component is shown, and Figure 9 A bottom view of the guide component is shown.

[0087] in addition, Figure 10 A plan view of the support and reflective components is shown, as well as... Figure 11 This is a bottom view of the support frame.

[0088] Reference Figures 5 to 11 The reflection module 300 (310, 320, 330) includes a reflection component 310, a bracket 330, and a guide component 320.

[0089] The reflecting member 310 has a reflective surface that reflects light passing through the first lens module 210. As an example, the reflecting member 310 may be a prism or a mirror.

[0090] When the reflecting member 310 is a prism, the reflecting member 310 can have any shape obtained by dividing a cuboid (or cube) in half diagonally. The prism includes an incident surface on which light is incident, a reflecting surface that reflects light passing through the incident surface, and an exiting surface from which light reflected from the reflecting surface is emitted.

[0091] The reflective member 310 is mounted on the bracket 330. The first lens module 210 may be disposed in front of the reflective member 310 or on the object side of the reflective member 310. In an exemplary embodiment, the first lens module 210 may be mounted on the bracket 330.

[0092] The bracket 330 can be rotatably mounted on the guide member 320. In addition, the guide member 320 can be rotatably mounted on the housing 100.

[0093] The guide member 320 can rotate about a first axis (X-axis) which is perpendicular to both the first optical axis (Y-axis) and the second optical axis (Z-axis). For example, the guide member 320 can rotate relative to the housing 100 about the first axis (X-axis). In this example, the first lens module 210 and the bracket 330 can also rotate together with the guide member 320. The first axis (X-axis) can also be referred to as the first rotation axis.

[0094] The support 330 can rotate about a second optical axis (Z-axis) that serves as a rotation axis, and the second optical axis (Z-axis) is perpendicular to the first axis (X-axis). For example, the support 330 can rotate relative to the guide member 320 about the second optical axis (Z-axis) that serves as a rotation axis. In this example, the first lens module 210 can rotate together with the support 330. In this example, the second optical axis (Z-axis) can also be referred to as the second rotation axis.

[0095] A first driver 400 can be configured to rotate the reflective module 300. The first driver 400 includes a drive magnet unit 410 and a coil unit 420. The guide member 320 can be rotated relative to the housing 100 based on a first axis (X-axis) via the first driver 400. Since the bracket 330 and the first lens module 210 can be mounted on the guide member 320, the bracket 330 and the first lens module 210 can also rotate together with the guide member 320.

[0096] The drive magnet unit 410 can be mounted on the bracket 330. In this example, the drive magnet unit 410 can be mounted on a side surface of the bracket 330. The side surface of the bracket 330 can refer to a surface of the bracket 330 facing the housing 100 in the first axis (X-axis) direction.

[0097] The driving magnet unit 410 may include a plurality of magnets. In an exemplary embodiment, the driving magnet unit 410 may include two magnets spaced apart from each other. The two magnets of the driving magnet unit 410 may be spaced apart from each other in the direction of a first axis (X-axis).

[0098] For example, the drive magnet unit 410 includes a first drive magnet 411 and a second drive magnet 412 spaced apart from each other in the direction of the first axis (X-axis).

[0099] The first driving magnet 411 can be disposed on one side surface of the bracket 330, and the second driving magnet 412 can be disposed on the other side surface of the bracket 330. One side surface of the bracket 330 and the other side surface of the bracket 330 can be spaced apart in the direction of the first axis (X-axis).

[0100] Coil unit 420 may include a plurality of coils. In an exemplary embodiment, coil unit 420 may include two coils spaced apart from each other. The two coils of coil unit 420 may be spaced apart from each other in a first axis (X-axis) direction.

[0101] In the example, coil unit 420 includes a first coil 421 and a second coil 422 spaced apart from each other in the direction of a first axis (X-axis). The first coil 421 may face the first driving magnet 411, and the second coil 422 may face the second driving magnet 412.

[0102] The first driving magnet 411 and the second driving magnet 412 can be magnetized such that a surface (e.g., the surface facing the coil unit 420) has both N and S poles.

[0103] In an exemplary embodiment, one surface of the first driving magnet 411 or the second driving magnet 412 facing the coil unit 420 and the other surface of the first driving magnet 411 or the second driving magnet 412 may be polarized to have different polarities in the direction of the first optical axis (Y axis).

[0104] For example, the first surface of the first driving magnet 411 may have a first polarity, a neutral region, and a second polarity sequentially along the first optical axis (Y-axis). The second surface of the first driving magnet 411 (e.g., the surface opposite to the first surface) may have a polarity opposite to that of the first surface of the first driving magnet 411.

[0105] The first surface of the second driving magnet 412 may sequentially have a first polarity, a neutral region, and a second polarity along the first optical axis (Y-axis). The second surface of the second driving magnet 412 (e.g., the surface opposite to the first surface) may have a polarity opposite to that of the first surface of the second driving magnet 412.

[0106] The first polarity and the second polarity can be opposite to each other. For example, when the first polarity is the N pole, the second polarity can be the S pole.

[0107] The coil unit 420 can be positioned facing the driving magnet unit 410. In an exemplary embodiment, the first coil 421 can be positioned facing the first driving magnet 411 in the first axis (X-axis) direction. The second coil 422 can be positioned facing the second driving magnet 412 in the first axis (X-axis) direction.

[0108] The coil unit 420 is disposed on the substrate 900, and the substrate 900 is mounted on the housing 100, such that the drive magnet unit 410 and the coil unit 420 face each other in the first axis (X-axis) direction.

[0109] The housing 100 is provided with a through hole penetrating the housing 100 in the first axis (X-axis) direction, and the coil unit 420 is disposed in the through hole to directly face the drive magnet unit 410.

[0110] When jitter correction is performed, the drive magnet unit 410 is a movable component mounted on the bracket 330 and rotating, and the coil unit 420 is a fixed component fixed to the substrate 900.

[0111] When power is applied to the first driver 400, the first driver 400 can generate the driving force required to rotate the bracket 330 and the guide member 320 about the first axis (X-axis) as the rotation axis. For example, the first driver 400 can generate a driving force in the direction of the first optical axis (Y-axis).

[0112] In an exemplary embodiment, a pair of magnets and a coil may be disposed on one side of the reflective module 300 (e.g., based on...). Figure 4 The first driving magnet 411 and the first coil 421 are disposed in the negative first axis direction (-X axis direction), and another pair of magnets and coils can be disposed on the other side of the reflection module 300 (e.g., based on...). Figure 4 The second driving magnet 412 and the second coil 422 are arranged in the positive first axis direction (+X axis direction).

[0113] When the guide member 320 and the bracket 330 rotate about the first axis (X-axis), the direction of the driving force of one pair of magnets and coils can be the same as the direction of the driving force of another pair of magnets and coils.

[0114] For example, when the driving force of the first driving magnet 411 and the first coil 421 is in the positive first optical axis (Y-axis) direction (+Y-axis direction), and the driving force of the second driving magnet 412 and the second coil 422 is also in the positive first optical axis (Y-axis) direction (+Y-axis direction), the guide member 320 and the bracket 330 can rotate together around the first axis (X-axis).

[0115] In addition, when the driving force of the first driving magnet 411 and the first coil 421 is in the negative first optical axis (Y-axis) direction (-Y-axis direction), and the driving force of the second driving magnet 412 and the second coil 422 is also in the negative first optical axis (Y-axis) direction (-Y-axis direction), the guide member 320 and the bracket 330 can rotate together around the first axis (X-axis).

[0116] The first ball member B1 can be disposed between the guide member 320 and the housing 100. The first ball member B1 can be disposed between the guide member 320 and the housing 100 to form the rotation axis of the guide member 320.

[0117] The first ball component B1 may include a plurality of balls spaced apart from each other in the direction of the first axis (X-axis). A virtual line v1 connecting the plurality of balls of the first ball component B1 in the direction of the first axis (X-axis) may be spaced apart from the first driver 400 in the direction of the second optical axis (Z-axis) (see [link]). Figure 18 ).

[0118] In an exemplary embodiment, the drive magnet unit 410 and the coil unit 420 may be spaced apart from the first ball member B1 in the direction of the second optical axis (Z-axis). When the drive magnet unit 410 and the coil unit 420 generate a driving force in the direction of the first optical axis (Y-axis), the bracket 330 may rotate about the rotation axis formed by the first ball member B1. Since the bracket 330 is disposed on the guide member 320, the bracket 330 and the guide member 320 may rotate together about the first axis (X-axis) by the first driver 400.

[0119] The virtual line v1 connecting the multiple spheres of the first sphere member B1 in the first axis (X-axis) direction can pass through the reflective surface of the reflective member 310.

[0120] In an exemplary embodiment, when viewed from the first axis (X-axis) direction, a line extending along the first optical axis (Y-axis) of the first lens module 210 may be positioned between the opposite ends of the plurality of spheres of the first sphere member B1. In the example, the opposite ends of the plurality of spheres of the first sphere member B1 may refer to opposite ends in the direction of the second optical axis (Z-axis).

[0121] An attractive force can be applied between the guide member 320 and the housing 100. A first traction member 510 can be disposed between the guide member 320 and the housing 100.

[0122] The first traction member 510 may include a first traction magnet 511 and a first traction yoke 512 facing each other. For example, the first traction magnet 511 may be disposed on one of the guide member 320 and the housing 100, and the first traction yoke 512 may be disposed on the other of the guide member 320 and the housing 100.

[0123] In an exemplary embodiment, the first traction magnet 511 may be disposed on the lower surface of the guide member 320, and the first traction yoke 512 may be disposed on the bottom surface of the housing 100. Alternatively, the first traction magnet 511 may be disposed on the bottom surface of the housing 100, and the first traction yoke 512 may be disposed on the lower surface of the guide member 320.

[0124] The first traction magnet 511 and the first traction yoke 512 can face each other in the direction of the first optical axis (Y axis).

[0125] The first traction magnet 511 and the first traction yoke 512 can generate an attractive force between them. In the example, the first traction yoke 512 can be formed of a magnetic material. In the example, the first traction yoke 512 can also be configured as a magnet.

[0126] The attractive force acts between the first traction magnet 511 and the first traction yoke 512 in the direction of the first optical axis (Y-axis).

[0127] The attraction between the first traction magnet 511 and the first traction yoke 512 allows the first ball member B1 to remain in contact with the guide member 320 and the housing 100, respectively.

[0128] One surface of the first traction magnet 511 facing the first traction yoke 512 can be configured to have multiple polarities. Therefore, the magnetic flux of the first traction magnet 511 can be concentrated on the first traction yoke 512, thereby minimizing magnetic flux leakage.

[0129] The first traction member 510 can be disposed between multiple balls of the first ball member B1.

[0130] The first guide groove g1 and the second guide groove g2 can be disposed on the respective surfaces of the guide member 320 and the housing 100 facing each other (e.g., surfaces facing each other in the direction of the first optical axis (Y-axis)). For example, the first guide groove g1 can be disposed on the housing 100, and the second guide groove g2 can be disposed on the guide member 320. The first guide groove g1 and the second guide groove g2 can face each other in the direction of the first optical axis (Y-axis).

[0131] The first guide groove g1 includes a plurality of grooves spaced apart from each other in the direction of the first axis (X-axis), and the second guide groove g2 includes a plurality of grooves spaced apart from each other in the direction of the first axis (X-axis).

[0132] The first ball component B1 can be disposed between the first guide groove g1 and the second guide groove g2 to form the rotation axis of the guide component 320.

[0133] One of the multiple slots in the first guide groove g1 can make three-point contact with the first ball member B1, while another slot can make two-point contact with the first ball member B1. For example, refer to... Figure 5 Among the multiple slots of the first guide groove g1, the slot on the left side can make contact with the first ball component B1 at three points, while the slot on the right side of the multiple slots of the first guide groove g1 can make contact with the first ball component B1 at two points.

[0134] Furthermore, each of the plurality of grooves in the second guide groove g2 can make three-point contact with the first ball member B1. However, this is merely an example, and the shapes of the first guide groove g1 and the second guide groove g2 can also be opposite.

[0135] The first driver 400 can rotate the bracket 330 around the second optical axis (Z-axis). That is, the bracket 330 can rotate around the second optical axis (Z-axis) via the first driver 400. Since the first lens module 210 is mounted on the bracket 330, the first lens module 210 can also rotate with the bracket 330.

[0136] When power is applied to the first driver 400, the first driver 400 can generate the driving force required to rotate the bracket 330 about the second optical axis (Z-axis) as the rotation axis. In the example, the first driver 400 can generate a driving force in the direction of the first optical axis (Y-axis).

[0137] In an exemplary embodiment, when the bracket 330 rotates about the second optical axis (Z-axis), the direction of the driving force of one pair of magnets and coils can be opposite to the direction of the driving force of the other pair of magnets and coils.

[0138] For example, when the driving force of the first driving magnet 411 and the first coil 421 is in the positive first optical axis (Y-axis) direction (+Y-axis direction), and the driving force of the second driving magnet 412 and the second coil 422 is in the negative first optical axis (Y-axis) direction (-Y-axis direction), the bracket 330 can rotate around the second optical axis (Z-axis).

[0139] In addition, when the driving force of the first driving magnet 411 and the first coil 421 is in the negative first optical axis (Y-axis) direction (-Y-axis direction), and the driving force of the second driving magnet 412 and the second coil 422 is in the positive first optical axis (Y-axis) direction (+Y-axis direction), the bracket 330 can rotate around the second optical axis (Z-axis).

[0140] Additionally, the bracket 330 can rotate diagonally. For example, the guide member 320 and the bracket 330 can rotate about a first axis (X-axis), and the bracket 330 can rotate about a second optical axis (Z-axis) to rotate the bracket 330 diagonally.

[0141] In an exemplary embodiment, the bracket 330 can be rotated diagonally by allowing driving force to be generated only in one pair of magnets and coils and preventing driving force from being generated in the other pair of magnets and coils. Alternatively, the bracket 330 can be rotated diagonally by generating driving force in one pair of magnets and coils in a different magnitude (and / or direction) than generating driving force in the other pair of magnets and coils.

[0142] The second ball component B2 can be disposed between the support 330 and the guide component 320. The second ball component B2 can be disposed between the support 330 and the guide component 320 to form the rotation axis of the support 330.

[0143] The second spherical component B2 may include a plurality of spheres spaced apart from each other along the second optical axis (Z-axis). A virtual line v2 connecting the plurality of spheres of the second spherical component B2 along the second optical axis (Z-axis) may be spaced apart from the first driver 400 along the first axis (X-axis) (see [link]). Figure 18 ).

[0144] In an exemplary embodiment, the drive magnet unit 410 and the coil unit 420 may be spaced apart from the second ball member B2 in the first axis (X-axis) direction. When the drive magnet unit 410 and the coil unit 420 generate a driving force in the first optical axis (Y-axis) direction, the support 330 may rotate about the rotation axis formed by the second ball member B2.

[0145] The virtual line v2 connecting the multiple spheres of the second sphere component B2 in the direction of the second optical axis (Z axis) can pass through the reflective surface of the reflective component 310.

[0146] In an exemplary embodiment, when viewed from the first axis (X-axis) direction, a line extending along the second optical axis (Z-axis) of the second lens module 220 can be positioned between the opposite ends of the plurality of spheres of the second sphere member B2. Here, the opposite ends of the plurality of spheres of the second sphere member B2 can refer to the opposite ends in the direction of the first optical axis (Y-axis).

[0147] The third guide groove g3 and the fourth guide groove g4 can be disposed on the respective surfaces of the bracket 330 and the guide member 320 facing each other (e.g., surfaces facing each other in the direction of the first optical axis (Y-axis)). In the example, the third guide groove g3 can be disposed on the guide member 320, and the fourth guide groove g4 can be disposed on the bracket 330. The third guide groove g3 and the fourth guide groove g4 can face each other in the direction of the first optical axis (Y-axis).

[0148] The third guide groove g3 includes a plurality of grooves spaced apart from each other in the direction of the second optical axis (Z-axis), and the fourth guide groove g4 includes a plurality of grooves spaced apart from each other in the direction of the second optical axis (Z-axis).

[0149] The second ball component B2 can be disposed between the third guide groove g3 and the fourth guide groove g4 to form the rotation axis of the support 330.

[0150] One of the multiple slots of the fourth guide groove g4 can make three-point contact with the second ball member B2, and another of the multiple slots of the fourth guide groove g4 can make two-point contact with the second ball member B2. For example, refer to Figure 11 The groove in the upper part of the fourth guide groove g4 can contact the second ball member B2 at three points, and the groove in the lower part of the fourth guide groove g4 can contact the second ball member B2 at two points.

[0151] Furthermore, each of the multiple slots in the third guide groove g3 can make three-point contact with the second ball member B2. The shapes of the third guide groove g3 and the fourth guide groove g4 can be opposite to each other.

[0152] An attractive force can be applied between the support 330 and the guide member 320. A second traction member 520 can be disposed between the support 330 and the guide member 320.

[0153] The second traction member 520 may include a second traction magnet 521 and a second traction yoke 522 facing each other. For example, the second traction magnet 521 may be disposed on one of the bracket 330 and the guide member 320, and the second traction yoke 522 may be disposed on the other of the bracket 330 and the guide member 320.

[0154] In an exemplary embodiment, the second traction magnet 521 may be disposed on the bracket 330, and the second traction yoke 522 may be disposed on the guide member 320. As another example, the second traction magnet 521 may be disposed on the guide member 320, and the second traction yoke 522 may be disposed on the bracket 330.

[0155] The second traction magnet 521 and the second traction yoke 522 can face each other in the direction of the first optical axis (Y axis).

[0156] In an exemplary embodiment, the second traction magnet 521 may be disposed on the lower surface of the bracket 330, and the second traction yoke 522 may be disposed on the upper surface of the guide member 320.

[0157] The second traction magnet 521 can be disposed between multiple slots of the fourth guide groove g4. Additionally, the second traction yoke 522 can be disposed between multiple slots of the third guide groove g3.

[0158] The second traction magnet 521 and the second traction yoke 522 can generate an attractive force between them. For example, the second traction yoke 522 can be formed of a magnetic material. The second traction yoke 522 can also be configured as a magnet.

[0159] An attractive force acts between the second traction magnet 521 and the second traction yoke 522 in the direction of the first optical axis (Y-axis). That is, the second traction member 520 can generate a force that pulls the guide member 320 and the bracket 330 together.

[0160] The attraction between the second traction magnet 521 and the second traction yoke 522 allows the second ball member B2 to remain in contact with the guide member 320 and the bracket 330, respectively.

[0161] One surface of the second traction magnet 521 facing the second traction yoke 522 can be configured to have multiple polarities. Therefore, the magnetic flux of the second traction magnet 521 can be concentrated on the second traction yoke 522, thereby minimizing magnetic flux leakage.

[0162] The second traction member 520 can be disposed between multiple balls of the second ball member B2.

[0163] Figure 12 It is a schematic cross-sectional view of the first magnetic component, the second magnetic component, and the second traction component, and Figure 13 and Figure 14 It is a view showing the attractive and repulsive forces acting between the guide member and the support.

[0164] The reflective module 300 according to an exemplary embodiment of the present disclosure may further include a plurality of magnetic components. In an exemplary embodiment, the plurality of magnetic components includes a first magnetic component 530 and a second magnetic component 540.

[0165] The first magnetic member 530 and the second magnetic member 540 may be spaced apart from each other in the direction of the first axis (X-axis). The second traction member 520 may be disposed between the first magnetic member 530 and the second magnetic member 540. For example, the first magnetic member 530 and the second magnetic member 540 may be spaced apart from each other in the direction of the first axis (X-axis) relative to the direction of the second optical axis (Z-axis).

[0166] In an exemplary embodiment, when viewed from the direction of the first optical axis (Y-axis), the second traction member 520 may be disposed between the first magnetic member 530 and the second magnetic member 540.

[0167] In an exemplary embodiment, a third plane passing through the second traction member 520 may be disposed between the first plane passing through the first magnetic member 530 and the second plane passing through the second magnetic member 540. Here, the first plane, the second plane, and the third plane may all be YZ planes.

[0168] The first magnetic component 530 includes a first magnet 531. In an exemplary embodiment, the first magnet 531 may be disposed on the guide component 320.

[0169] The second magnetic component 540 includes a second magnet 541. In an exemplary embodiment, the second magnet 541 may be disposed on the guide component 320.

[0170] The first magnet 531 and the second magnet 541 can be spaced apart from each other in the direction of the first axis (X-axis).

[0171] The first magnetic component 530 may further include a third magnet 532. The first magnet 531 and the third magnet 532 may face each other in the direction of the first optical axis (Y-axis).

[0172] The third magnet 532 can be installed in the bracket 330.

[0173] The first magnetic component 530 can generate a force that pushes the guide component 320 and the support 330. For example, a repulsive force acting between the first magnet 531 and the third magnet 532.

[0174] A surface of the first magnet 531 and a surface of the third magnet 532 facing each other can have the same polarity. For example, a surface of the first magnet 531 and a surface of the third magnet 532 facing each other can both have an N pole. Conversely, a surface of the first magnet 531 and a surface of the third magnet 532 facing each other can be configured to both have an S pole.

[0175] The second magnetic component 540 may further include a fourth magnet 542. The second magnet 541 and the fourth magnet 542 may face each other in the direction of the first optical axis (Y-axis).

[0176] The fourth magnet 542 can be installed in the bracket 330.

[0177] The second magnetic component 540 can generate a force that pushes the guide component 320 and the support 330. For example, a repulsive force can act between the second magnet 541 and the fourth magnet 542.

[0178] A surface of the second magnet 541 and a surface of the fourth magnet 542, which are opposite each other, can have the same polarity. For example, the first surface of the second magnet 541 and the first surface of the fourth magnet 542 can both have an N pole. Conversely, the first surface of the second magnet 541 and the first surface of the fourth magnet 542 can both have an S pole.

[0179] In an exemplary embodiment, the direction of the magnetic force of the second traction member 520 may be opposite to the direction of the magnetic force of the first magnetic member 530. Additionally, the direction of the magnetic force of the second traction member 520 may be opposite to the direction of the magnetic force of the second magnetic member 540.

[0180] Both attractive and repulsive forces can occur between the guide member 320 and the support 330. In the example, the area where the attractive force acts can be the central area of ​​the portions of the guide member 320 and the support 330 that face each other, and the area where the repulsive force acts can be the outer area of ​​the portions of the guide member 320 and the support 330 that face each other.

[0181] In addition, the area on which the attractive force acts can be set to be closer to the second spherical member B2 than the area on which the repulsive force acts.

[0182] The magnitude of the attractive force of the second traction member 520 can be greater than the sum of the magnitude of the repulsive force of the first magnetic member 530 and the magnitude of the repulsive force of the second magnetic member 540.

[0183] Therefore, the second ball component B2 can maintain contact with the guide component 320 and the bracket 330 respectively.

[0184] In an exemplary embodiment, the area in which the second traction magnet 521 and the second traction yoke 522 of the second traction member 520 face each other may be greater than the sum of the area in which the magnets of the first magnetic member 530 face each other and the area in which the magnets of the second magnetic member 540 face each other.

[0185] In an exemplary embodiment, the gap between the second traction magnet 521 and the second traction yoke 522 of the second traction member 520 may be narrower than the gap between the first magnet 531 and the third magnet 532 of the first magnetic member 530.

[0186] The gap between the second traction magnet 521 and the second traction yoke 522 of the second traction member 520 may be narrower than the gap between the second magnet 541 and the fourth magnet 542 of the second magnetic member 540.

[0187] When the rotation of the bracket 330 brings one side of the first magnet 531 and the other side of the third magnet 532 relatively close, the repulsive force between the two sides increases, thereby allowing the bracket 330 to return to its initial position without power being applied to the reflective module 300.

[0188] In the example, the initial position refers to the state in which the support 330 does not rotate, for example, the state in which the first magnet 531 and the third magnet 532 are parallel to each other (or the state in which the second magnet 541 and the fourth magnet 542 are parallel, or the state in which the second traction magnet 521 and the second traction yoke 522 are parallel).

[0189] In other words, according to one or more embodiments, the reflection module 300 can mechanically implement an alignment structure for the bracket 330 to reduce the power consumption of positioning the bracket 330.

[0190] Therefore, when jitter correction is not required (e.g., when power is not supplied to the reflection module 300), the position of the bracket 330 can be adjusted without additional power consumption.

[0191] In the example, the attractive and repulsive force structure between the support 330 and the guide member 320 can also be applied between the guide member 320 and the housing 100.

[0192] In this example, the first magnetic component 530 and the second magnetic component 540 may be disposed between the guide component 320 and the housing 100, and the first magnetic component 530 and the second magnetic component 540 may be spaced apart from each other in the direction of the second optical axis (Z axis).

[0193] Figure 15 It is a 3D view of the reflection module and the first lens module, and Figure 16 It is shown Figure 15 The modified example view.

[0194] First, refer to Figure 15 The camera module 1 can detect the position of the bracket 330. For this purpose, a position sensing unit 600 is provided.

[0195] When rotating around the first axis (X-axis), the guide member 320 and the bracket 330 rotate together, and when rotating around the second optical axis (Z-axis), the bracket 330 rotates relative to the guide member 320. In addition, since the bracket 330 may be equipped with a reflective member 310, the position of the reflective member 310 can be sensed by sensing the position of the bracket 330.

[0196] The position sensing unit 600 includes a sensing magnet 610 and a first position sensor 620.

[0197] The sensing magnet 610 can be disposed on the support 330. For example, the sensing magnet 610 can be disposed on the rear surface of the support 330. One surface of the sensing magnet 610 (e.g., the surface facing the first position sensor 620) can be magnetized to have an N pole, a neutral region, and an S pole in the direction of the first optical axis (Y axis).

[0198] The first position sensor 620 can be positioned facing the sensing magnet 610 (e.g., facing the direction of the second optical axis (Z-axis)). The first position sensor 620 can be positioned on the substrate 900.

[0199] In the initial position, the neutral region of the sensing magnet 610 can face the first position sensor 620. In the example, the initial position can refer to the state in which the support 330 and the guide member 320 are not rotating, for example, the state in which the second traction magnet 521 and the second traction yoke 522 are parallel to the bottom surface of the housing 100.

[0200] When the guide member 320 and the bracket 330 rotate about the first axis (X-axis) which is the axis of rotation, the distance between the sensing magnet 610 and the first position sensor 620 changes in the direction of the second optical axis (Z-axis), thereby detecting the position of the guide member 320.

[0201] When the bracket 330 rotates about the second optical axis (Z-axis) which is the axis of rotation, the polarity region of a surface of the sensing magnet 610 facing the first position sensor 620 changes, thereby detecting the position of the bracket 330.

[0202] The first position sensor 620 can be a Hall sensor or a tunneling magnetoresistive (TMR) sensor.

[0203] In the example, the sensing magnet 610 may include a plurality of magnets spaced apart from each other in the direction of the first axis (X-axis), and the first position sensor 620 may include a plurality of Hall sensors spaced apart from each other in the direction of the first axis (X-axis).

[0204] When multiple sensing magnets 610 and first position sensors 620 are configured, the accuracy of position sensing can be improved.

[0205] In an exemplary embodiment, the plurality of sensing magnets 610 may be spaced apart from each other. For example, the plurality of sensing magnets 610 may be spaced apart from each other in the direction of a first axis (X-axis).

[0206] Additionally, a virtual line v2 connecting the plurality of spheres of the second sphere member B2 can be disposed between the plurality of sensing magnets 610. The distance from the virtual line v2 connecting the plurality of spheres of the second sphere member B2 to each sensing magnet 610 can be the same.

[0207] Each sensing magnet 610 has a surface (e.g., the surface facing the first position sensor 620) that can sequentially have an S pole, a neutral region, and an N pole in the positive first optical axis (Y-axis) direction (+Y-axis direction). That is, the polarity magnetization shapes of multiple sensing magnets 610 can be exactly the same.

[0208] The following describes the sensing method of the position sensing unit 600 when the polarity magnetization shapes of multiple sensing magnets 610 are the same.

[0209] When the guide member 320 and the bracket 330 rotate about the first axis (X-axis) which is the axis of rotation, all of the multiple first position sensors 620 can move away from the same polarity or move closer to the same polarity.

[0210] For example, by rotating the guide member 320 and the bracket 330, all the first position sensors 620 can move away from the N pole and towards the S pole, or all the first position sensors 620 can move away from the S pole and towards the N pole. Therefore, the signal values ​​output from the multiple first position sensors 620 have the same shape.

[0211] When the guide member 320 and the bracket 330 rotate about the first axis (X-axis) which is the axis of rotation, the position of the bracket 330 can be accurately detected by summing the signal values ​​output from the multiple first position sensors 620.

[0212] When the bracket 330 rotates around the second optical axis (Z-axis), as one of the plurality of first position sensors 620 moves closer to the N pole and away from the S pole, another of them can move closer to the S pole and away from the N pole. Therefore, the signal value output from one of the plurality of first position sensors 620 can have a different shape than the signal value output from another of them.

[0213] For example, when the signal value output from one of the plurality of first position sensors 620 is in the form of an upward-sloping straight line, the signal value output from another of the plurality of first position sensors 620 can be in the form of a downward-sloping straight line. In other words, the graph of the signal values ​​output from the plurality of first position sensors 620 can be in the form of an X.

[0214] When the bracket 330 rotates around the second optical axis (Z-axis) which serves as the rotation axis, the difference between the signal values ​​output from the multiple first position sensors 620 can be calculated to accurately detect the position of the bracket 330.

[0215] In an exemplary embodiment, one surface of one of the plurality of sensing magnets 610 may have an S pole, a neutral region, and an N pole sequentially in the positive first optical axis (Y-axis) direction (+Y-axis direction). Additionally, one surface of another of the plurality of sensing magnets 610 may have an N pole, a neutral region, and an S pole sequentially in the positive first optical axis (Y-axis) direction (+Y-axis direction).

[0216] The following describes the sensing method of the position sensing unit 600 when the polarity magnetization shapes of the multiple sensing magnets 610 are different.

[0217] In the example where the guide member 320 and the bracket 330 rotate about the first axis (X-axis), when one of the plurality of first position sensors 620 moves closer to the N pole and away from the S pole, another of them can move closer to the S pole and away from the N pole. Therefore, the signal value output from one of the plurality of first position sensors 620 can have a different shape than the signal value output from another of them.

[0218] For example, when the signal value output from one of the plurality of first position sensors 620 is in the form of an upward-sloping straight line, the signal value output from another of the plurality of first position sensors 620 can be in the form of a downward-sloping straight line. In other words, the graph of the signal values ​​output from the plurality of first position sensors 620 can be in the form of an X.

[0219] When the guide member 320 and the bracket 330 rotate about a first axis (X-axis) which is the axis of rotation, the difference between the signal values ​​output from the plurality of first position sensors 620 can be calculated to accurately detect the position of the guide member 320.

[0220] When the support 330 rotates about the second optical axis (Z-axis), which serves as the rotation axis, all sensors in the plurality of first position sensors 620 move away from or towards the same polarity. For example, by rotating the support 330, all the first position sensors 620 can move away from the N pole and towards the S pole, or all of the plurality of first position sensors 620 can move away from the S pole and towards the N pole. Therefore, the signal values ​​output from the plurality of first position sensors 620 have the same shape.

[0221] When the bracket 330 rotates around the second optical axis (Z-axis) which serves as the axis of rotation, the position of the bracket 330 can be accurately detected by summing the signal values ​​output from multiple first position sensors 620.

[0222] In summary, the signal values ​​output from multiple first position sensors 620 can be added together to generate a first position signal of the bracket 330, and the difference between the signal values ​​output from multiple first position sensors 620 can be calculated to generate a second position signal of the bracket 330.

[0223] In the example, the first position signal may be a position signal indicating that the bracket 330 rotates about a first rotation axis or rotates about a second rotation axis, and the second position signal may be a position signal indicating that the bracket 330 rotates about a first rotation axis or rotates about a second rotation axis.

[0224] The position sensing unit 600 may also include a controller. The controller may be a driver IC. In an exemplary embodiment, the driver IC and the first position sensor 620 may be configured as a single chip.

[0225] By providing feedback control to the signal values ​​output from the multiple first position sensors 620, the position sensing unit 600 can apply power of appropriate direction and magnitude to the coil unit 420 so that the bracket 330 and the guide member 320 can be positioned at the target location.

[0226] Reference Figure 17 The reflection module 300 may also include a gyroscope. The gyroscope can be a sensor that senses the attitude value of the support 330. Alternatively, when the reflection module 300 does not include a gyroscope, a gyroscope mounted on a portable electronic device can be used. That is, since the reflection module 300 is mounted on a portable electronic device, the output value of a gyroscope mounted on the portable electronic device can be used.

[0227] When a jitter correction value is calculated based on the attitude value (target OIS A or target OIS B) output from the gyroscope and input to the controller, the controller can apply current to at least one of the first coil 421 and the second coil 422. This allows the support 330 to rotate.

[0228] exist Figure 17 In this context, A can refer to either rotation around the first axis (X-axis) or rotation around the second optical axis (Z-axis). Therefore, when A refers to rotation around the first axis (X-axis), B can refer to rotation around the second optical axis (Z-axis).

[0229] For example, in Figure 17 In this context, target OIS A can be the target position of the bracket 330 rotating around the first axis (X-axis). Target OIS B can be the target position of the bracket 330 rotating around the second optical axis (Z-axis). Driving force A can be the driving force that causes the bracket 330 to rotate around the first axis (X-axis), while driving force B can be the driving force that causes the bracket 330 to rotate around the second optical axis (Z-axis). Position detection A can refer to sensing the position of the bracket 330 based on the first axis (X-axis), while position detection B can refer to sensing the position of the bracket 330 based on the second optical axis (Z-axis).

[0230] When the first driving magnet 411 and the second driving magnet 412 have the same polarity and magnetization, current in the same direction can be applied to the first coil 421 and the second coil 422, thereby generating a driving force to cause the guide member 320 and the bracket 330 to rotate around the first axis (X-axis). Figure 17 The “Sum” symbol for the coils in the diagram can indicate that current is applied in the same direction to the first coil 421 and the second coil 422.

[0231] Alternatively, currents in opposite directions can be applied to the first coil 421 and the second coil 422 to generate a driving force, causing the bracket 330 to rotate about the second optical axis (Z-axis). Figure 17 The symbol “Diff” in the diagram can represent applying currents in opposite directions to the first coil 421 and the second coil 422.

[0232] However, the one or more examples are not limited thereto, and in order to generate driving force in one direction, the magnetization form of the polarity of the plurality of driving magnet units 410 and the direction of current application of the coil unit 420 can be configured in various ways.

[0233] The position of the bracket 330 can be accurately detected by summing the signal values ​​output from the multiple first position sensors 620. Alternatively, the position of the bracket 330 can be accurately detected by calculating the difference between the signal values ​​output from the multiple first position sensors 620.

[0234] In addition, by feedback control of the signal values ​​output from the multiple first position sensors 620, an appropriate direction and magnitude of power can be applied to the coil unit 420 so that the bracket 330 and the guide member 320 can be positioned at the target location.

[0235] When the bracket 330 is set in the initial position, the virtual line v1 connecting the plurality of balls of the first ball member B1 can overlap with the neutral region of the sensing magnet 610 when viewed from the second optical axis (Z-axis). In addition, when viewed from the second optical axis (Z-axis), the virtual line v1 connecting the plurality of balls of the first ball member B1 can overlap with the first position sensor 620.

[0236] When viewed from the first axis (X-axis), the virtual line v2 connecting the plurality of spheres of the second sphere member B2 can overlap with the neutral region of the sensing magnet 610. Additionally, when viewed from the first axis (X-axis), the virtual line v2 connecting the plurality of spheres of the second sphere member B2 can overlap with the first position sensor 620.

[0237] Reference Figure 15The drive magnet unit 410 of the first driver 400 is disposed on two side surfaces of the bracket 330 spaced apart from each other in the first axis (X-axis) direction, and the sensing magnet 610 of the position sensing unit 600 is disposed on the rear surface of the bracket 330, which is perpendicular to the two side surfaces of the bracket 330.

[0238] and Figure 15 The positions of the first driver 400 and the position sensing unit 600 can also be interchanged.

[0239] When the positions of the first driver 400 and the position sensing unit 600 are interchanged, the sensing magnet 610 of the position sensing unit 600 can be disposed on two side surfaces of the bracket 330 spaced apart from each other in the first axis (X-axis) direction, and the driving magnet unit 410 of the first driver 400 can be disposed on the rear surface of the bracket 330, which is perpendicular to the two side surfaces of the bracket 330. In this example, the first driving magnet 411 and the second driving magnet 412 of the driving magnet unit 410 can be spaced apart from each other in the first axis (X-axis) direction on the rear surface of the bracket 330.

[0240] In the example, refer to Figure 16 The position sensing unit 600' can be configured to include only a plurality of first position sensors, and may not include a plurality of sensing magnets. That is, in Figure 16 In an exemplary embodiment, the position sensing unit 600' does not include a plurality of sensing magnets 610.

[0241] In this example, multiple first position sensors can be set at locations where the position of the drive magnet unit 410 can be detected (e.g., the magnetic field of the first drive magnet 411 and the magnetic field of the second drive magnet 412 can pass through the position of the first position sensor).

[0242] In an exemplary embodiment, a plurality of first position sensors may be disposed inside or outside the coil unit 420.

[0243] Reference Figure 16 One of the plurality of first position sensors is shown disposed inside the first coil 421, and another is shown disposed inside the second coil 422. However, one or more examples are not limited thereto, and the plurality of first position sensors may also be disposed outside the first coil 421 and outside the second coil 422.

[0244] Position sensing method of bracket 330 and Figure 15 The position sensing method of the bracket 330 in the embodiment is the same.

[0245] In the example, although not shown in the figures, a spacer can be provided on the lower surface of the first lens module 210 (i.e., the lower surface of the first lens holder 212 facing the reflecting member 310). This spacer has an inlet hole for light to pass through, and this inlet hole can be non-circular. For example, the inlet hole can have a shape similar to a runway. That is, the inner surface of the spacer forming the inlet hole can include two flat surfaces extending parallel to each other and two curved surfaces connecting these two flat surfaces.

[0246] The inner surface of the spacer can have alternating concave and convex waveforms to prevent flare phenomena.

[0247] Reference Figure 4 The camera module 1 may include a first stop 340. The first stop 340 may be coupled to the housing 100 to cover at least a portion of the reflector module 300. For example, the first stop 340 may cover at least a portion of the upper surface of the bracket 330. The first stop 340 and the bracket 330 may be spaced apart from each other in the direction of a first optical axis (Y-axis). In addition, the first stop 340 and the bracket 330 may be spaced apart from each other in the direction of a second optical axis (Z-axis).

[0248] Since the first stop 340 is spaced apart from the reflective module 300, it can prevent the reflective module 300 from deviating from the housing 100 due to external impacts, etc., and does not hinder the rotation of the reflective module 300.

[0249] A spring-loaded buffer member 341 can be connected to the first stop member 340. The buffer member 341 can be disposed on at least one of a first surface and a second surface of the first stop member 340. The first surface of the first stop member 340 can be the surface facing the housing 110 in the first optical axis (Y-axis) direction, and the second surface of the first stop member 340 can be the surface facing the bracket 330 in the first optical axis (Y-axis) direction.

[0250] Alternatively, the buffer member 341 may also be disposed on the side surface of the first stop member 340. The side surface of the first stop member 340 may be the surface facing the bracket 330 in the second optical axis (Z-axis) direction.

[0251] In the example, the second stop 350 may be coupled to the guide member 320 or the bracket 330. In an exemplary embodiment, the second stop 350 may be fixed to the bracket 330, and a portion of the second stop 350 may extend toward the guide member 320. The bracket 330 may be provided with a connecting portion for the second stop 350 to engage. The connecting portion may have a groove shape or a hole shape.

[0252] A receiving portion that accommodates a part of the second stop 350 may be disposed in the guide member 320. The receiving portion may have a groove shape or a hole shape.

[0253] The second stop 350 can be fixed to the connecting portion of the bracket 330, and a portion of the second stop 350 can extend toward the guide member 320 and be accommodated in the receiving portion of the guide member 320.

[0254] A portion of the second stop 350 may be spaced apart from the receiving portion. An end of a portion of the second stop 350 may extend curvedly within the receiving portion. A portion of the second stop 350 and the receiving portion of the guide member 320 may have compatible shapes.

[0255] In an exemplary embodiment, the end of this portion of the second stop 350 and the receiving portion may face each other in the direction of the first optical axis (Y axis).

[0256] Therefore, the second stop 350 can prevent the bracket 330 from deviating from the guide member 320 due to external impacts, etc., and does not hinder the rotation of the bracket 330.

[0257] The buffer member 101 may be disposed on at least one of the surfaces of the guide member 320 and the housing 100 facing each other (e.g., the surface facing the first lens module 210 in the first optical axis (Y axis) direction).

[0258] For example, refer to Figure 19 The elastic buffer member 101 can be disposed on the inner bottom surface of the housing 100. The inner bottom surface of the housing 100 can be the surface facing the guide member 320 in the first optical axis (Y-axis) direction. As another example, the buffer member 101 can be disposed on the lower surface of the guide member 320 (e.g., the surface facing the inner bottom surface of the housing 100 in the first optical axis (Y-axis) direction).

[0259] Therefore, when the guide member 320 rotates around the first axis (X-axis), the rotation range can be limited, and when the guide member 320 collides with the housing 100, the amount of impact and noise can be reduced.

[0260] The buffer member can be disposed on at least one of the surfaces of the bracket 330 and the first stop 340 that face each other (e.g., the surface facing the first lens module 210 in the direction of the first optical axis (Y axis).

[0261] For example, refer to Figure 7 The buffer member 331 can be disposed on the upper surface of the bracket 330 (the surface facing the lower surface of the first stop member 340 in the direction of the first optical axis (Y axis)). The buffer member 331 can be formed of an elastic material.

[0262] Therefore, when the bracket 330 rotates around the second optical axis (Z-axis), the rotation range can be limited, and when the bracket 330 collides with the first stop 340, the impact and noise can be reduced.

[0263] Figure 20 This is a perspective view showing the second lens module separated from the camera module according to one or more embodiments, and Figure 21 This is a bottom-view stereoscopic view of the second lens module.

[0264] Reference Figure 20 The second lens module 220 can be disposed between the reflection module 300 and the image sensor module 800.

[0265] The second lens module 220 can move in the direction of the second optical axis (Z axis) for the purpose of performing focus adjustment.

[0266] In an exemplary embodiment, the second lens module 220 includes a second lens barrel 221 and a second lens support 222. Multiple lenses may be disposed within the second lens barrel 221, and the second lens barrel 221 may be connected to the second lens support 222.

[0267] The camera module 1 may include a second driver 700 to move the second lens module 220 in the direction of the second optical axis (Z axis).

[0268] The second driver 700 includes a third driving magnet 710 and a third coil 720. The third driving magnet 710 and the third coil 720 can be configured to face each other in a direction perpendicular to the second optical axis (Z-axis).

[0269] The third driving magnet 710 is mounted on the second lens module 220. For example, the third driving magnet 710 may be disposed on the side surface of the second lens module 220.

[0270] In an exemplary embodiment, the third driving magnet 710 may include two magnets, and one magnet of the third driving magnet 710 may be mounted on the first side surface of the second lens module 220, and the other magnet of the third driving magnet 710 may be mounted on the second side surface of the second lens module 220. The first side surface and the second side surface of the second lens module 220 may be spaced apart from each other in the direction of the first axis (X-axis).

[0271] The third driving magnet 710 can be magnetized such that one of its surfaces (e.g., the surface facing the third coil 720) has both an N pole and a S pole. For example, the surface of the third driving magnet 710 facing the third coil 720 may be provided with an N pole, a neutral region, and an S pole sequentially along the second optical axis (Z-axis).

[0272] The third coil 720 is configured to face the third driving magnet 710. For example, the third coil 720 may be configured to face the third driving magnet 710 in a direction perpendicular to the second optical axis (Z-axis) (e.g., in the first axis (X-axis) direction).

[0273] The third coil 720 is disposed on the substrate 900, and the substrate 900 is mounted on the housing 100 such that the third driving magnet 710 and the third coil 720 face each other in the first axis (X-axis) direction. In an exemplary embodiment, the third coil 720 may include two coils spaced apart from each other in the first axis (X-axis) direction.

[0274] The housing 100 is provided with a through hole that penetrates the housing 100, and the third coil 720 provided on the substrate 900 can directly face the third driving magnet 710 through the through hole.

[0275] During focus adjustment, the third drive magnet 710 is a motion member mounted on the second lens module 220 and moving together with the second lens module 220 in the direction of the second optical axis (Z axis), and the third coil 720 is a fixing member fixed to the substrate 900.

[0276] When power is applied to the third coil 720, the second lens module 220 can move in the direction of the second optical axis (Z axis) by the electromagnetic force between the third drive magnet 710 and the third coil 720.

[0277] The third spherical component B3 is disposed between the second lens module 220 and the housing 100, and the second lens module 220 can be guided by the third spherical component B3 to move in the direction of the second optical axis (Z-axis). The third spherical component B3 includes a plurality of spheres.

[0278] The third traction magnet 730 can be disposed on the lower surface of the second lens module 220, and the third traction yoke can be disposed on the inner bottom surface of the housing 100. The third traction yoke can be formed of a magnetic material.

[0279] The third traction magnet 730 can be positioned closer to the second lens module 220. That is, the third traction magnet 730 can be positioned closer to the second lens module 220 than the other side of the second lens module 220. Additionally, the third traction magnet 730 can be positioned between one side of the second lens module 220 and the second optical axis (Z-axis).

[0280] The third traction magnet 730 and the third traction yoke can be configured to face each other in the direction of the first optical axis (Y-axis).

[0281] The third traction magnet 730 and the third traction yoke can generate an attractive force between each other. For example, this attractive force acts between the third traction magnet 730 and the third traction yoke in the direction of the first optical axis (Y-axis).

[0282] The attraction between the third traction magnet 730 and the third traction yoke allows the third ball component B3 to contact the second lens module 220 and the housing 100, respectively.

[0283] Some of the spheres in the third sphere component B3 can be positioned close to the first side surface of the second lens module 220, and the other spheres in the third sphere component B3 can be positioned close to the second side surface of the second lens module 220. The number of spheres positioned between the first side surface of the second lens module 220 and the second optical axis (Z-axis) can be greater than the number of spheres positioned between the second side surface of the second lens module 220 and the second optical axis (Z-axis).

[0284] In an exemplary embodiment, the third spherical component B3 may include at least three spheres. When three spheres are provided, two of the spheres may be disposed between the first side surface of the second lens module 220 and the second optical axis (Z-axis), and one of the spheres may be disposed between the second side surface of the second lens module 220 and the second optical axis (Z-axis).

[0285] The two spheres positioned between the first side surface of the second lens module 220 and the second optical axis (Z-axis) can be spaced apart from each other in the direction of the second optical axis (Z-axis).

[0286] The fifth guide groove g5 and the sixth guide groove g6 can be disposed on at least one of the surfaces of the second lens module 220 and the housing 100 facing each other. For example, the fifth guide groove g5 can be disposed on the first side of the lower surface of the second lens module 220, and the sixth guide groove g6 can be disposed on the second side of the lower surface of the second lens module 220.

[0287] The fifth guide groove g5 and the sixth guide groove g6 can be spaced apart from each other in a direction perpendicular to the second optical axis (Z axis) (e.g., in the direction of the first axis (X axis)).

[0288] The fifth guide groove g5 and the sixth guide groove g6 extend in a direction parallel to the second optical axis (Z axis).

[0289] Some of the balls in the third ball component B3 can be placed in the fifth guide groove g5, and the other balls in the third ball component B3 can be placed in the sixth guide groove g6.

[0290] The number of contact points between some of the balls in the third ball component B3 and the fifth guide groove g5 can be greater than the number of contact points between the other balls in the third ball component B3 and the sixth guide groove g6.

[0291] The fifth guide groove g5 is positioned closer to a side surface of the second lens module 220 than the sixth guide groove g6.

[0292] The third traction magnet 730 can be configured to be closer to the fifth guide slot g5 than the sixth guide slot g6.

[0293] In an exemplary embodiment, camera module 1 can detect the position of second lens module 220. For this purpose, a second position sensor 740 is provided. The second position sensor 740 can be positioned facing the third drive magnet 710 of the second driver 700 (e.g., facing the first axis (X-axis) direction).

[0294] Therefore, when the second lens module 220 moves in the direction of the second optical axis (Z axis), the position of the second lens module 220 can be detected by the second position sensor 740.

[0295] The second position sensor 740 can be a Hall sensor or a TMR sensor, for example only.

[0296] In the example, refer to Figure 21 The second lens module 220 may also include a light-shielding plate 223. The light-shielding plate 223 may be connected to the second lens module 220.

[0297] The first and second side surfaces of the second lens module 220 may extend from the second lens module 220 respectively in the direction of the second optical axis (Z-axis). A portion of the first side surface and a portion of the second side surface of the second lens module 220 may face each other in the direction of the first axis (X-axis). A space may be formed between the portion of the first side surface and the portion of the second side surface of the second lens module 220.

[0298] The light-shielding plate 223 can be disposed in the space between a portion of the first side surface of the second lens module 220 and a portion of the second side surface of the second lens module 220.

[0299] The light shield 223 prevents light passing through the second lens module 220 from being reflected unintended within the housing 100. Therefore, flare phenomena can be suppressed.

[0300] The camera module 1 may also include a third stop 750. The third stop 750 may be coupled to the housing 100 and may cover at least a portion of the second lens module 220.

[0301] In an exemplary embodiment, the third stop 750 may be configured to face the upper surface of the second lens module 220 in the first optical axis (Y-axis) direction. The first and second sides of the third stop 750 may extend curvedly in the first optical axis (Y-axis) direction to face the second lens module 220 in the second optical axis (Z-axis) direction.

[0302] The elastic buffer member 751 can be connected to the third stop member 750. For example, the buffer member 751 can be installed on the first side and the second side of the third stop member 750 facing the second lens module 220 in the direction of the second optical axis (Z axis).

[0303] Additionally, the buffer member can be installed on at least one of the surfaces of the third stop 750 and the second lens module 220 that face each other in the direction of the first optical axis (Y-axis).

[0304] Figures 22 to 25 This is a view showing a modified example of the first and second magnetic components of the reflective module.

[0305] first, Figure 22 The reflective module is positioned relative to the reference in relation to the first magnetic component 530 and the second magnetic component 540. Figures 1 to 14 The exemplary embodiments described are different.

[0306] Reference Figure 22 The first magnetic member 530 and the second magnetic member 540 may be spaced apart from each other in the direction of the first axis (X-axis). The second traction member 520 may be disposed between the first magnetic member 530 and the second magnetic member 540. For example, the first magnetic member 530 and the second magnetic member 540 may be spaced apart from each other in the direction of the first axis (X-axis) with respect to the direction of the second optical axis (Z-axis).

[0307] The first magnetic component 530 includes a first magnet 531 and a third magnet 532. The first magnet 531 and the third magnet 532 may face each other in the direction of the first axis (X-axis).

[0308] A first magnet 531 may be disposed on one of the support 330 and the guide member 320, and a third magnet 532 may be disposed on the other of the support 330 and the guide member 320. In an exemplary embodiment, the first magnet 531 is disposed on an outer surface of the guide member 320, while the third magnet 532 is disposed on an inner surface of the support 330.

[0309] The repulsive force acts between the first magnet 531 and the third magnet 532.

[0310] A surface of the first magnet 531 and a surface of the second magnet 532, which face each other in the first axis (X-axis) direction, may have the same polarity.

[0311] The second magnetic component 540 includes a second magnet 541 and a fourth magnet 542. The second magnet 541 and the fourth magnet 542 may face each other in the direction of the first axis (X-axis).

[0312] A third magnet 541 may be disposed on one of the bracket 330 and the guide member 320, and a fourth magnet 542 may be disposed on the other of the bracket 330 and the guide member 320. In an exemplary embodiment, a second magnet 541 is disposed on another outer surface of the guide member 320, and a fourth magnet 542 is disposed on another inner surface of the bracket 330.

[0313] The repulsive force acts between the second magnet 541 and the fourth magnet 542.

[0314] A surface of the second magnet 541 and a surface of the fourth magnet 542, which face each other in the first axis (X-axis) direction, may have the same polarity.

[0315] The gap between the second traction magnet 521 and the second traction yoke 522 of the second traction member 520 may be narrower than the gap between the first magnet 531 and the third magnet 532 of the first magnetic member 530.

[0316] The gap between the second traction magnet 521 and the second traction yoke 522 of the second traction member 520 may be narrower than the gap between the second magnet 541 and the fourth magnet 542 of the second magnetic member 540.

[0317] Figure 23 and Figure 24 The reflective module is similar to the reference in terms of the configuration and position of the first magnetic component 530' and the second magnetic component 540'. Figures 1 to 14 The exemplary embodiments described are different.

[0318] Reference Figure 23 and 24 The first magnetic member 530' and the second magnetic member 540' may be spaced apart from each other in the direction of the first axis (X-axis). The second traction member 520 may be disposed between the first magnetic member 530' and the second magnetic member 540'. For example, the first magnetic member 530' and the second magnetic member 540' may be spaced apart from each other in the direction of the first axis (X-axis) with respect to the direction of the second optical axis (Z-axis).

[0319] The first magnetic member 530' may include a first magnet 531 disposed on the guide member 320. For example, the first magnet 531 may be disposed on an outer surface of the guide member 320.

[0320] The first surface of the first magnet 531 may face the first driving magnet 411 disposed on the first side surface of the support 330. For example, the first surface of the first magnet 531 may face the second surface of the first driving magnet 411 (e.g., the surface opposite to the surface facing the first coil 421) in the first axis (X-axis) direction.

[0321] A repulsive force can act between the first magnet 531 and the first driving magnet 411. In an exemplary embodiment, the first surface of the first magnet 531 and the second surface of the first driving magnet 411, which are opposite to each other, can be configured to have the same polarity.

[0322] The first surface of the first driving magnet 411 faces the first coil 421 and has a first polarity and a second polarity spaced apart from each other in the direction of the first optical axis (Y-axis). In addition, the second surface of the first driving magnet 411 has a polarity opposite to that of the first surface of the first driving magnet 411.

[0323] Here, the first surface of the first magnet 531 is arranged in one of the first polarity and the second polarity of the second surface of the first driving magnet 411 facing the first axis (X-axis) in the direction of the first axis.

[0324] For example, when the second surface of the first driving magnet 411 has a downward-facing N pole and an upward-facing S pole in the first optical axis (Y-axis) direction, the first surface of the first magnet 531 can face the N pole of the first driving magnet 411. Since a side surface of the bracket 330 on which the first driving magnet 411 is mounted can be disposed between the first magnet 531 and the first driving magnet 411, one surface of the first magnet 531 can face the N pole of the first driving magnet 411, while a side surface of the bracket 330 is located between the two.

[0325] The first surface of the first magnet 531 has a single polarity, and one polarity of the first surface of the first magnet 531 is the same as the polarity of the second surface of the first driving magnet 411 facing the first surface of the first magnet 531.

[0326] In the initial position, the uppermost end of the first surface of the first magnet 531 (one end in the direction of the positive first optical axis (Y axis)) can be positioned below the uppermost end of the polarity (e.g., N pole) of the second surface of the first driving magnet 411 facing the first surface of the first magnet 531 (one end in the direction of the positive first optical axis (Y axis)).

[0327] The second magnetic member 540' may include a second magnet 541 disposed on the guide member 320. For example, the second magnet 541 may be disposed on another outer surface of the guide member 320.

[0328] The first surface of the second magnet 541 may face the second driving magnet 412 disposed on the second side surface of the support 330. For example, the first surface of the second magnet 541 may face the second surface of the second driving magnet 412 in the first axis (X-axis) direction (e.g., the surface opposite to a surface facing the second coil 422).

[0329] A repulsive force can act between the second magnet 541 and the second driving magnet 412. In an exemplary embodiment, the first surfaces of the second magnet 541 and the second surfaces of the second driving magnet 412, which face each other, can be configured to have the same polarity.

[0330] The first surface of the second driving magnet 412 faces the second coil 422 and has a first polarity and a second polarity spaced apart from each other in the direction of the first optical axis (Y-axis). The second surface of the second driving magnet 412 has a polarity opposite to that of one surface of the second driving magnet 412.

[0331] In the example, the first surface of the second magnet 541 is configured to have one of a first polarity and a second polarity facing the second surface of the second driving magnet 412 in the direction of the first axis (X-axis).

[0332] For example, when the second surface of the second driving magnet 412 has a downward-pointing N pole and an upward-pointing S pole in the first optical axis (Y-axis) direction, the first surface of the second magnet 541 can face the N pole of the second driving magnet 412. Since the second side surface of the bracket 330 on which the second driving magnet 412 is mounted can be disposed between the second magnet 541 and the second driving magnet 412, the first surface of the second magnet 541 can face the N pole of the second driving magnet 412, while one side surface of the bracket 330 is located between the two.

[0333] The first surface of the second magnet 541 has a single polarity, and one polarity of the first surface of the second magnet 541 is the same as the polarity of the second surface of the second driving magnet 412 facing the first surface of the second magnet 541.

[0334] In the initial position, the uppermost end of the first surface of the second magnet 541 (e.g., one end in the direction of the positive first optical axis (Y-axis)) can be positioned below the uppermost end of the polarity (e.g., N pole) of the second surface of the second driving magnet 412 facing the first surface of the second magnet 541 (one end in the direction of the positive first optical axis (Y-axis)).

[0335] The gap between the second traction magnet 521 and the second traction yoke 522 of the second traction member 520 can be narrower than the gap between the first magnetic member 530' and the first driving magnet 411.

[0336] The gap between the second traction magnet 521 and the second traction yoke 522 of the second traction member 520 can be narrower than the gap between the second magnetic member 540' and the second driving magnet 412.

[0337] Figure 25 The reflective module is similar to the reference in terms of the configuration and position of the first magnetic component 550 and the second magnetic component 560. Figures 1 to 14 The exemplary embodiments described are different.

[0338] Reference Figure 25 The first magnetic member 550 and the second magnetic member 560 may be spaced apart from each other in the direction of the first axis (X-axis). The second traction member 520 may be disposed between the first magnetic member 550 and the second magnetic member 560. For example, the first magnetic member 550 and the second magnetic member 560 may be spaced apart from each other in the direction of the first axis (X-axis) relative to the direction of the second optical axis (Z-axis).

[0339] The first magnetic component 550 includes a first magnet 551 and a first yoke 552. The first magnet 551 and the first yoke 552 may face each other in the direction of the first axis (X-axis).

[0340] The first magnet 551 may be disposed on one of the support 330 and the guide member 320, and the first yoke 552 may be disposed on the other. In an exemplary embodiment, the first magnet 551 is disposed on the inner surface of the support 330, and the first yoke 552 is disposed on the outer surface of the guide member 320.

[0341] The attractive force acts between the first magnet 551 and the first yoke 552.

[0342] The second magnetic component 560 includes a second magnet 561 and a second yoke 562. The second magnet 561 and the second yoke 562 may face each other in the direction of the first axis (X-axis).

[0343] The second magnet 561 may be disposed on one of the support 330 and the guide member 320, and the second yoke 562 may be disposed on the other of the support 330 and the guide member 320. In an exemplary embodiment, the second magnet 561 is disposed on another inner surface of the support 330, and the second yoke 562 is disposed on another outer surface of the guide member 320.

[0344] An attractive force acts between the second magnet 561 and the second yoke 562.

[0345] The gap between the second traction magnet 521 and the second traction yoke 522 of the second traction member 520 may be narrower than the gap between the first magnet 551 and the first yoke 552 of the first magnetic member 550.

[0346] The gap between the second traction magnet 521 and the second traction yoke 522 of the second traction member 520 may be narrower than the gap between the second magnet 561 and the second yoke 562 of the second magnetic member 560.

[0347] The attraction between the first magnet 551 and the first yoke 552 can be balanced with the attraction between the second magnet 561 and the second yoke 562, thereby allowing the bracket 330 to return to its initial position when no power is applied to the reflective module 300.

[0348] Figure 26 This is an exploded perspective view of an exemplary camera module according to one or more embodiments.

[0349] Reference Figure 26 An exemplary camera module 2 according to one or more embodiments includes a reflection module 3000 and a housing 1000, and may also include a first lens module 2100.

[0350] Figure 26 The exemplary embodiment differs from the previously described exemplary embodiment in the configuration of the first driver 4000.

[0351] The first lens module 2100 can be connected to the reflection module 3000. For example, the first lens module 2100 can be connected to the bracket 3300 of the reflection module 3000.

[0352] In an exemplary embodiment, the camera module 2 may further include a second lens module 2200. The reflection module 3000 is disposed between the first lens module 2100 and the second lens module 2200.

[0353] The first optical axis (Y-axis) of the first lens module 2100 and the second optical axis (Z-axis) of the second lens module 2200 can be formed to be perpendicular to each other.

[0354] The first lens module 2100 includes one or more lenses, and the second lens module 2200 includes multiple lenses.

[0355] For the purpose of performing shake correction, the first lens module 2100 and the reflection module 3000 can be configured to rotate together. For the purpose of performing focus adjustment, the second lens module 2200 can move in the direction of the second optical axis (Z axis).

[0356] The reflection module 3000 includes a reflection component 310 ( Figure 4), bracket 3300 and guide component 3200.

[0357] The reflecting member 310 has a reflective surface that reflects light passing through the first lens module 2100. As an example, the reflecting member 310 may be a prism or a mirror.

[0358] The reflective member 310 is mounted on the bracket 3300. The first lens module 2100 may be disposed in front of the reflective member 310. In an exemplary embodiment, the first lens module 2100 may be mounted on the bracket 3300.

[0359] The bracket 3300 is rotatably mounted on the guide member 3200. In addition, the guide member 3200 is rotatably mounted on the housing 1000.

[0360] The guide member 3200 can rotate about a first axis (X-axis) which is perpendicular to both the first optical axis (Y-axis) and the second optical axis (Z-axis). As an example, the guide member 3200 can rotate relative to the housing 1000 about the first axis (X-axis). In this example, the first lens module 2100 and the bracket 3300 can also rotate together with the guide member 3200. In this example, the first axis (X-axis) can also be referred to as the first rotation axis.

[0361] The bracket 3300 can rotate about a second optical axis (Z-axis) that serves as a rotation axis, and the second optical axis (Z-axis) is perpendicular to the first axis (X-axis). For example, the bracket 3300 can rotate relative to the guide member 3200 about the second optical axis (Z-axis) that serves as a rotation axis. In this example, the first lens module 2100 can rotate together with the bracket 3300. In this example, the second optical axis (Z-axis) can also be referred to as the second rotation axis.

[0362] A first driver 4000 can be configured to rotate the reflector module 3000. The first driver 4000 includes a drive magnet unit 4100 and a coil unit 4200.

[0363] The first driver 4000 allows the guide member 3200 to rotate about a first axis (X-axis) relative to the housing 1000. Since the bracket 3300 and the first lens module 2100 are mounted on the guide member 3200, the bracket 3300 and the first lens module 2100 can also rotate together with the guide member 3200.

[0364] The first driver 4000 allows the bracket 3300 to rotate relative to the guide member 3200 about the second optical axis (Z-axis). Since the first lens module 2100 is disposed in the bracket 3300, the first lens module 2100 can also rotate together with the bracket 3300.

[0365] The drive magnet unit 4100 can be mounted on the bracket 3300. In the example, the drive magnet unit 4100 can be mounted on the side surface of the bracket 3300.

[0366] The driving magnet unit 4100 includes a plurality of magnets. For example, the driving magnet unit 4100 may include a first driving magnet 4100a, a second driving magnet 4100b, a third driving magnet 4100c, and a fourth driving magnet 4100d.

[0367] The bracket 3300 includes a first side surface 3301, a second side surface 3302, a third side surface, and a fourth side surface 3304. The first side surface 3301 and the second side surface 3302 can be surfaces disposed on the first side of the bracket 3300 based on the second optical axis (Z-axis), and the third side surface and the fourth side surface 3304 can be surfaces disposed on the second side of the bracket 3300 based on the second optical axis (Z-axis).

[0368] The first side surface 3301 and the second side surface 3302 are spaced apart from each other in the direction of the second optical axis (Z axis), and the third side surface and the fourth side surface 3304 are spaced apart from each other in the direction of the second optical axis (Z axis).

[0369] In addition, the first side surface 3301 and the fourth side surface 3304 are spaced apart from each other in the first axis (X-axis) direction, and the second side surface 3302 and the third side surface are spaced apart from each other in the first axis (X-axis) direction.

[0370] The first driving magnet 4100a can be disposed on the first side surface 3301 of the bracket 3300, the second driving magnet 4100b can be disposed on the second side surface 3302 of the bracket 3300, the third driving magnet 4100c can be disposed on the third side surface of the bracket 3300, and the fourth driving magnet 4100d can be disposed on the fourth side surface 3304 of the bracket 3300.

[0371] The first ball component B1 can be disposed between the first side surface 3301 and the second side surface 3302 of the bracket 3300, and between the third side surface and the fourth side surface 3304.

[0372] Coil unit 4200 includes a plurality of coils. For example, coil unit 4200 may include a first coil 4200a facing a first driving magnet 4100a, a second coil 4200b facing a second driving magnet 4100b, a third coil 4200c facing a third driving magnet 4100c, and a fourth coil 4200d facing a fourth driving magnet 4100d.

[0373] In the example, coil unit 4200 can be disposed on substrate 9000.

[0374] When power is applied to the first driver 4000, the first driver 4000 can generate the driving force required to rotate the bracket 3300 and the guide member 3200 about a first axis (X-axis) which serves as the axis of rotation, and the driving force required to rotate the bracket 3300 about a second optical axis (Z-axis). For example, the first driver 4000 can rotate the bracket 3300 and the guide member 3200 by adjusting the driving force of four pairs of magnets and coils.

[0375] In an exemplary embodiment, among the four pairs of magnets and coils, the driving forces of the magnets and coils that are diagonally spaced apart from each other can be in opposite directions. For example, the first coil 4200a and the third coil 4200c can be connected in series. Therefore, the direction of the driving force between the first driving magnet 4100a and the first coil 4200a can be opposite to the direction of the driving force between the third driving magnet 4100c and the third coil 4200c.

[0376] However, coils arranged diagonally are not necessarily connected in series and can also be controlled individually.

[0377] When the direction of the driving force generated by the first driving magnet 4100a and the first coil 4200a is the positive first optical axis (Y-axis) direction (+Y-axis direction), the direction of the driving force generated by the third driving magnet 4100c and the third coil 4200c arranged in the diagonal direction can be the negative first optical axis (Y-axis) direction (-Y-axis direction).

[0378] When the direction of the driving force generated by the second driving magnet 4100b and the second coil 4200b is the negative first optical axis (Y-axis) direction (-Y-axis direction), the direction of the driving force generated by the fourth driving magnet 4100d and the fourth coil 4200d arranged in the diagonal direction can be the positive first optical axis (Y-axis) direction (+Y-axis direction).

[0379] Therefore, when the direction of the driving force of the first driving magnet 4100a and the first coil 4200a is the same as the direction of the driving force of the fourth driving magnet 4100d and the fourth coil 4200d (e.g., the positive first optical axis (Y-axis) direction (+Y-axis direction)), and when the direction of the driving force of the second driving magnet 4100b and the second coil 4200b is the same as the direction of the driving force of the third driving magnet 4100c and the third coil 4200c (e.g., the negative first optical axis (Y-axis) direction (-Y-axis direction)), the bracket 3300 and the guide member 3200 can rotate based on the first axis (X-axis).

[0380] When the direction of the driving force of the first driving magnet 4100a and the first coil 4200a is the same as the direction of the driving force of the second driving magnet 4100b and the second coil 4200b (e.g., positive first optical axis (Y-axis) direction (+Y-axis direction)), and when the direction of the driving force of the third driving magnet 4100c and the third coil 4200c is the same as the direction of the driving force of the fourth driving magnet 4100d and the fourth coil 4200d (e.g., negative first optical axis (Y-axis) direction (-Y-axis direction)), the bracket 3300 can rotate based on the second optical axis (Z-axis).

[0381] In addition, by controlling the power applied to the first coil 4200a and the third coil 4200c, as well as the power applied to the second coil 4200b and the fourth coil 4200d, the support 3300 can also rotate in a diagonal direction.

[0382] For example, when power is applied to the first coil 4200a and the third coil 4200c but not to the second coil 4200b and the fourth coil 4200d, the support 3300 can rotate in a diagonal direction.

[0383] The position sensing method for the bracket 3300 and the guide member 3200 is the same as that in the aforementioned exemplary embodiments, so a detailed description thereof will be omitted.

[0384] While this disclosure includes specific examples, it will be apparent upon understanding the disclosure of this application that various changes in form and detail may be made to these examples without departing from the spirit and scope of the claims and their equivalents. The examples described herein are to be understood in a descriptive sense only and not for purposes of limitation.
