Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of Korean Patent Application No. 10-2023-0086734 filed on July 4, 2023, and Korean Patent Application No. 10-2023-0171563 filed on November 30, 2023, in the Korean Intellectual Property Office, the disclosures of which are incorporated herein in their entirety by reference for all purposes. Technical Field

[0003] The present disclosure relates to a camera module and an aperture module. Background Art

[0004] Recently, camera modules have been adopted in portable electronic devices such as smart phones, tablet PCs, and laptop computers.

[0005] Furthermore, recently, an aperture module for controlling the amount of light has been applied to a mobile camera module.

[0006] Since the amount of light incident to the camera module can be adjusted by the aperture module, good quality images can be obtained even under various illumination conditions.

[0007] The lens module of the camera module can be moved for focus adjustment and optical image stabilization. In this case, in a structure in which the aperture module is fixed, the distance between the lens module and the aperture module may change, so that it may be difficult to meet the required driving characteristics.

[0008] Furthermore, when the aperture module is configured to move together with the lens module, focus adjustment and optical image stabilization performance may be deteriorated due to the weight of the aperture module and the lens module. Utility Model Content

For clarity, illustration, and convenience, the drawings may not be drawn to scale, and the relative sizes, proportions, and depictions of the elements in the drawings may be exaggerated. DETAILED DESCRIPTION

[0060] The following specific embodiments are provided to help the reader obtain a comprehensive understanding of the methods, devices and / or systems described herein. However, after understanding the disclosure of the present application, various changes, modifications and equivalents of the methods, devices and / or systems described herein will be apparent. For example, the order of operations described herein is only an example and is not limited to the order set forth herein, but can be changed as will be apparent after understanding the disclosure of the present application, except for operations that must occur in a certain order. In addition, in order to improve clarity and brevity, the description of features known in the art may be omitted.

[0061] The features described herein may be implemented in different forms and are not to be construed as being limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways to implement the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0062] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, or “coupled to” another element, it may be directly “on”, directly “connected to”, or directly “coupled to” the other element, or one or more other elements may be present between them. Conversely, when an element is described as being “directly” “on”, “directly connected to”, or “directly coupled to” another element, there are no other elements present between them.

[0063] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more of the associated listed items.

[0064] Although terms such as "first", "second", and "third" may be used herein to describe various members, components, regions, layers, or portions, these members, components, regions, layers, or portions are not limited by these terms. Instead, these terms are only used to distinguish one member, component, region, layer, or portion from another member, component, region, layer, or portion. Therefore, the first member, first component, first region, first layer, or first portion mentioned in the examples described herein may also be referred to as the second member, second component, second region, second layer, or second portion without departing from the teachings of the examples.

[0065] For ease of description, spatially relative terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another element as shown in the drawings. In addition to the orientation depicted in the drawings, such spatially relative terms are intended to also include different orientations of the device in use or operation.

Therefore, the term "above" includes both the orientation of the above and below, depending on the spatial orientation of the device. The device may also be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatially relative terms used herein will be interpreted accordingly.

[0066] The terms used herein are only used to describe various examples and are not used to limit the present disclosure. The words "a", "an" and "the" are intended to include plural forms as well, unless the context clearly indicates otherwise. The terms "include", "comprises" and "have" specify the presence of stated features, quantities, operations, components, elements and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements and / or combinations thereof.

[0067] In an embodiment, the optical axis (Z axis) direction may refer to the direction along the lens module 200 (see Figure 1 )'s direction extending up and down from the optical axis (Z axis) or a direction parallel to the optical axis (Z axis).

[0068] The first axis (X axis) direction may refer to a direction perpendicular to the optical axis (Z axis) direction, and the second axis (Y axis) direction may refer to a direction perpendicular to both the optical axis (Z axis) direction and the first axis (X axis) direction.

[0069] The embodiments relate to a camera module, and the camera module may be installed in a portable electronic device such as a mobile communication terminal, a smart phone, and a tablet PC.

[0070] Figure 1 is an exploded perspective view showing a camera module according to an embodiment of the present disclosure. Figure 2It is shown Figure 1 An exploded perspective view of the aperture module of a camera module. Figure 3 is shown as viewed from below Figure 2 A perspective view of the base portion of the aperture module.

[0071] Reference Figures 1 to 3 , the camera module 1 according to the embodiment may include an aperture module 100 , a lens module 200 , and a housing 300 .

[0072] The aperture module 100 may be disposed in the housing 300 and may control the amount of light incident to the camera module 1. For example, the aperture module 100 may selectively change the amount of light incident to the camera module 1. In other words, the aperture module 100 may control the f-number of the camera module 1.

[0073] The aperture module 100 may have an incident hole through which light passes, and may adjust the amount of light incident to the camera module 1 by changing the size of the incident hole.

[0074] For example, in a high illumination environment, a relatively small amount of light may be incident on the camera module 1, whereas in a low illumination environment, a relatively large amount of light may be incident on the camera module 1. Therefore, image quality may be consistently maintained even under various illumination conditions.

[0075] The aperture module 100 can move in one or more directions of three axes intersecting each other. For example, the aperture module 100 can move in one or more directions of the optical axis (Z axis), the first axis (X axis) and the second axis (Y axis).

[0076] In an embodiment, the aperture module 100 may be configured to move in an optical axis (Z-axis) direction, a first axis (X-axis) direction, and a second axis (Y-axis) direction.

[0077] The first axis (X axis) direction and the second axis (Y axis) direction may be perpendicular to the optical axis (Z axis) direction. In addition, the first axis (X axis) direction and the second axis (Y axis) direction may be perpendicular to each other.

[0078] The lens module 200 can move in one or more directions of three axes intersecting each other. For example, the lens module 200 can move in one or more directions of the optical axis (Z axis), the first axis (X axis) and the second axis (Y axis).

[0079] In an embodiment, the lens module 200 may be configured to move in an optical axis (Z-axis) direction, a first axis (X-axis) direction, and a second axis (Y-axis) direction.

[0080] The lens module 200 may be coupled to the aperture module 100. The lens module 200 may include a first lens unit 210 and a second lens unit 230 spaced apart from each other in the optical axis (Z axis) direction. The first lens unit 210 may include one or more lenses, and the second lens unit 230 may include a plurality of lenses.

[0081] The aperture module 100 may be disposed between the first lens unit 210 and the second lens unit 230. For example, the first lens unit 210 may be coupled to an upper portion of the aperture module 100, and the second lens unit 230 may be coupled to a lower portion of the aperture module 100.

[0082] When the aperture module 100 is disposed between the first lens unit 210 and the second lens unit 230, a desired f-number can be achieved while reducing a moving distance between a plurality of blades of the aperture module 100. Therefore, the f-number can be adjusted with low power.

[0083] The aperture module 100 and the lens module 200 may be coupled to each other and may move together.

[0084] That is, the aperture module 100 and the lens module 200 can move together in the optical axis (Z axis) direction for focus adjustment. In addition, the aperture module 100 and the lens module 200 can move together in a direction perpendicular to the optical axis (Z axis) for optical image stabilization.

[0085] In order to move the aperture module 100 and the lens module 200 , the camera module 1 may further include an actuator driving unit.

[0086] The actuator driving unit may include one or both of the focus adjustment unit 500 and the optical image stabilization unit 600 .

[0087] In an embodiment, the actuator driving unit may refer to one of the focus adjustment unit 500 and the optical image stabilization unit 600 , or may refer to both of the focus adjustment unit 500 and the optical image stabilization unit 600 .

[0088] The aperture module 100 and the lens module 200 can move together in the optical axis (Z axis) direction through the focus adjustment unit 500. Through the optical image stabilization unit 600, the aperture module 100 and the lens module 200 can move together in the first axis (X axis) direction and the second axis (Y axis) direction.

[0089] During focus adjustment and optical image stabilization, the lens module 200 and the aperture module 100 may move together so that a relative position between the lens module 200 and the aperture module 100 does not change.

[0090] Reference Figure 2The aperture module 100 may include a base portion 110 , a plurality of blades, and an aperture driving unit 170 .

[0091] The plurality of blades may include a first blade 120 and a second blade 130. In this embodiment, two blades may be provided, but the number of the plurality of blades is not limited thereto.

[0092] The first blade 120 may include a first through hole 121 , and the second blade 130 may include a second through hole 131 .

[0093] A portion of the first blade 120 and a portion of the second blade 130 may be arranged to overlap each other in the optical axis (Z axis) direction. A portion of the first blade 120 and a portion of the second blade 130 may overlap each other in the optical axis (Z axis) direction, and may form an incident hole through which light passes. The incident hole may be defined by the first through hole 121 and the second through hole 131.

[0094] Each of the first through hole 121 and the second through hole 131 may have a shape having an open side. In addition, the shapes of the first through hole 121 and the second through hole 131 may be opposite to each other. The first blade 120 and the second blade 130 may rotate around the first protrusion 111 of the base 110. The first through hole 121 and the second through hole 131 may have a symmetrical shape in the rotation direction.

[0095] The positions of the first blade 120 and the second blade 130 may be changed by the aperture driving unit 170. Therefore, the size of the entrance aperture may be changed according to the positions of the first blade 120 and the second blade 130. For example, the first blade 120 and the second blade 130 may be configured to rotate in opposite directions by the aperture driving unit 170.

[0096] The size of the incident aperture defined by the first through hole 121 and the second through hole 131 may be changed by changing the positions of the first blade 120 and the second blade 130. According to the shapes of the first through hole 121 and the second through hole 131, the incident aperture may have a circular shape or a polygonal shape.

[0097] The first blade 120 may include a first rotation hole 122, and the second blade 130 may include a second rotation hole 132. For example, the first blade 120 may have the first rotation hole 122 on the outer side end, and the first rotation hole 122 may have a shape that penetrates the first blade 120 in the optical axis (Z axis) direction. In addition, the second blade 130 may have the second rotation hole 132 on the outer side end, and the second rotation hole 132 may have a shape that penetrates the second blade 130 in the optical axis (Z axis) direction.

[0098] The first blade 120 and the second blade 130 may be coupled to the base 110. For example, a first protrusion 111 protruding in the optical axis (Z axis) direction may be provided on the base 110, and the first rotation hole 122 of the first blade 120 and the second rotation hole 132 of the second blade 130 may be inserted into the first protrusion 111.

[0099] The first protrusion 111 may form a rotation axis of the first blade 120 and the second blade 130. The first rotation hole 122 and the second rotation hole 132 may have a circular shape so that the first blade 120 and the second blade 130 rotate using the first protrusion 111 as a rotation axis.

[0100] The first blade 120 may include a first guide hole 123, and the second blade 130 may include a second guide hole 133. The first guide hole 123 may have a long shape in one direction, and the second guide hole 133 may have a long shape in another direction.

[0101] A portion of the first guide hole 123 and a portion of the second guide hole 133 may be arranged to overlap each other in the optical axis (Z axis) direction. In addition, the first guide hole 123 and the second guide hole 133 may be arranged to have an inclination relative to each other on a plane perpendicular to the optical axis (Z axis).

[0102] Each of the first guide hole 123 of the first blade 120 and the second guide hole 133 of the second blade 130 may be coupled to a holder 171 which will be described later. When the holder 171 moves, the first blade 120 and the second blade 130 may rotate in opposite directions using the first protrusion 111 as a rotation axis.

[0103] The aperture driving unit 170 may include an aperture magnet 174 and an aperture coil 175 .

[0104] One of the aperture magnet 174 and the aperture coil 175 may be provided on the aperture module 100, and the other of the aperture magnet 174 and the aperture coil 175 may be provided on the housing 300. In the following description, an embodiment in which the aperture magnet 174 is provided on the aperture module 100 will be described.

[0105] The aperture module 100 may further include a holder 171 configured to move relative to the base 110 .

[0106] The holder 171 may be provided on the base 110 so that the holder 171 can move in a direction perpendicular to the optical axis (Z axis). The aperture magnet 174 may be mounted on the holder 171. The aperture coil 175 may be provided on the housing 300 facing the aperture magnet 174. For example, the substrate 700 may be provided on the housing 300, and the aperture coil 175 may be provided on one surface of the substrate 700.

[0107] The aperture magnet 174 may be magnetized so that one surface (e.g., the surface facing the aperture coil 175) may have both an N pole and an S pole. As an example, an N pole, a neutral region, and an S pole may be sequentially disposed on one surface of the aperture magnet 174 facing the aperture coil 175 in a direction perpendicular to the optical axis (Z axis) (e.g., the moving direction of the holder 171).

[0108] The aperture magnet 174 and the holder 171 can be movable components configured to move in the optical axis (Z axis) direction, the first axis (X axis) direction and the second axis (Y axis) direction together with the base 110, and the aperture coil 175 can be a fixed component fixed to the housing 300.

[0109] The holder 171 may be disposed on the first side wall 113 of the base part 110. The first side wall 113 of the base part 110 may have a shape extending from the upper surface of the base part 110 in the optical axis (Z-axis) direction.

[0110] The holder 171 is movable relative to the first side wall 113 of the base portion 110 in a direction perpendicular to the optical axis (Z axis).

[0111] For example, the aperture magnet 174 may be disposed on the holder 171 , and the holder 171 may move in a direction perpendicular to the optical axis (Z axis) in response to an electromagnetic force generated by the aperture magnet 174 and the aperture coil 175 .

[0112] The rolling member RB may be disposed between the first side wall 113 of the base 110 and the holder 171. For example, the rolling member RB may be disposed between the first side wall 113 of the base 110 and the holder 171, and may reduce friction when the holder 171 moves.

[0113] The rolling member RB may include a plurality of balls, and when the holder 171 moves in a direction perpendicular to the optical axis (Z axis), the plurality of balls may roll in the direction perpendicular to the optical axis (Z axis).

[0114] The pulling yoke 173 may be disposed on the first side wall 113 of the base portion 110. The pulling yoke 173 may be disposed at a position facing the aperture magnet 174.

[0115] The aperture magnet 174 and the pulling yoke 173 may generate an attractive force therebetween. For example, the pulling yoke 173 may be made of a magnetic material.

[0116] Due to the attractive force generated between the aperture magnet 174 and the pulling yoke 173 , the rolling member RB may maintain contact with each of the first side wall 113 of the base 110 and the holder 171 of the aperture module 100 .

[0117] The accommodation groove 177 may be formed in surfaces of the first side wall 113 of the base part 110 and the holder 171 facing each other. The rolling member RB may be disposed in the accommodation groove 177 .

[0118] In an implementation, the camera module 1 may sense the position of the holder 171 in a direction perpendicular to the optical axis (Z axis).

[0119] To this end, an aperture position sensor 176 may be provided. The aperture position sensor 176 may be disposed on the substrate 700 facing the aperture magnet 174. The aperture position sensor 176 may be a Hall sensor.

[0120] The holder 171 may include a guide protrusion 172 protruding in the optical axis (Z-axis) direction The guide protrusion 172 may be inserted into the first guide hole 123 of the first blade 120 and the second guide hole 133 of the second blade 130 .

[0121] For example, a portion of the first guide hole 123 and a portion of the second guide hole 133 may overlap in the optical axis (Z-axis) direction, and the guide protrusion 172 may be inserted into the overlapping portion.

[0122] As the holder 171 moves in the direction perpendicular to the optical axis (Z axis), the guide protrusion 172 may also move in the direction perpendicular to the optical axis (Z axis) in the first guide hole 123 and the second guide hole 133 .

[0123] Therefore, as the holder 171 moves, the first blade 120 and the second blade 130 may rotate in opposite directions using the first protrusion 111 of the base 110 as a rotation axis.

[0124] By changing the positions of the first blade 120 and the second blade 130 , incident holes of various sizes can be formed.

[0125] The aperture module 100 may further include a cover 160, a first spacer 140, and a second spacer 150. The cover 160 may be coupled to the base 110, and a plurality of blades may be disposed in a space between the cover 160 and the base 110. In addition, the first spacer 140 may be disposed between the cover 160 and the plurality of blades, and the second spacer 150 may be disposed between the plurality of blades and the base 110.

[0126] The first spacer 140 may have a through hole through which light passes, and may be coupled to the base 110. The size of the through hole of the first spacer 140 may be greater than the maximum size of the incident hole formed by the plurality of blades.

[0127] The first spacer 140 may cover at least a portion of the upper surface of the plurality of blades. A surface of the first spacer 140 may be coated in black.

[0128] The second spacer 150 may have a through hole through which light passes, and may be coupled to the base 110. The size of the through hole of the second spacer 150 may be larger than the maximum size of the incident hole formed by the plurality of blades. In addition, the size of the through hole of the second spacer 150 may be smaller than the size of the through hole of the first spacer 140.

[0129] The second spacer 150 may cover at least a portion of the lower surface of the plurality of blades. A surface of the second spacer 150 may be coated in black.

[0130] The first spacer 140 and the second spacer 150 may be coupled to the second protrusion 112 of the base part 110 .

[0131] The aperture module 100 may be disposed between the first lens unit 210 and the second lens unit 230. For example, the first lens unit 210 may be coupled to the upper surface of the cover 160 of the aperture module 100. The second lens unit 230 may be accommodated in the base part 110. For example, the second lens unit 230 may be coupled to the inner bottom surface of the base part 110 (see Figure 3 The inner bottom surface of the base 110 may be an inner surface of the base 110 that faces away from the upper surface of the base 110 (a surface of the base 110 that faces the cover 160 in the optical axis (Z-axis) direction).

[0132] The upper surface of the cover 160 of the aperture module 100 may include a first groove 161, and the inner bottom surface of the base 110 may include a second groove ( Figure 3 not shown).

[0133] The first lens unit 210 may be coupled to the first groove 161 , and the second lens unit 230 may be coupled to the second groove.

[0134] The first groove 161 and the second groove may have a function of guiding a coupling position of the first lens unit 210 and a coupling position of the second lens unit 230 so that the optical axis (Z axis) of the first lens unit 210 and the optical axis (Z axis) of the second lens unit 230 may be aligned.

[0135] Reference Figure 1 , the camera module 1 according to the embodiment may further include a carrier 400 , a housing 310 , and an image sensor module 800 .

[0136] The carrier 400 may be disposed in the housing 300 , and may be configured to move relative to the housing 300 in an optical axis (Z-axis) direction.

[0137] The housing 300 may have a shape in which the upper and lower portions thereof are opened, the carrier 400 may be disposed in an inner space of the housing 300 , and the aperture module 100 and the lens module 200 may be accommodated in the carrier 400 .

[0138] The carrier 400 , the lens module 200 , and the aperture module 100 may be configured to move together in the optical axis (Z axis) direction. Therefore, the distance between the lens module 200 and the image sensor 810 may be changed to adjust the focus of the camera module 1 .

[0139] Furthermore, the lens module 200 and the aperture module 100 may be configured to move in a direction perpendicular to the optical axis (Z-axis) direction to correct shaking during imaging.

[0140] The camera module 1 may include an actuator driving unit. The actuator driving unit may generate a driving force in one or more directions of an optical axis (Z axis), a first axis (X axis), and a second axis (Y axis). The actuator driving unit may include one or more magnets and one or more coils.

[0141] For example, the actuator driving unit may include a focus adjustment unit 500 generating a driving force in the optical axis (Z axis) direction, and an optical image stabilization unit 600 generating a driving force in a direction perpendicular to the optical axis (Z axis) direction.

[0142] The image sensor module 800 may be a device for converting incident light passing through the lens module 200 into an electrical signal.

[0143] As an example, the image sensor module 800 may include an image sensor 810 and a printed circuit board 830 to which the image sensor 810 is connected, and may further include an infrared cut filter (not shown).

[0144] The infrared cut filter may block light in an infrared region among light incident through the lens module 200 .

[0145] The image sensor 810 may convert incident light passing through the lens module 200 into an electrical signal. As an example, the image sensor 810 may be a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS) device.

[0146] The electrical signal converted by the image sensor 810 may be output as an image through a display unit of a portable electronic device in which the camera module 1 is installed.

[0147] The image sensor 810 may be fixed to the printed circuit board 830 and may be electrically connected to the printed circuit board 830 through wire bonding.

[0148] The image sensor module 800 may be disposed in a lower portion of the housing 300 .

[0149] The housing 310 may be coupled to the case 300 to surround an outer surface of the case 300 , and may play a role in protecting internal components of the camera module 1 .

[0150] The focus adjustment unit 500 may move the aperture module 100 and the lens module 200 to focus on the object. For example, the focus adjustment unit 500 may move the carrier 400 by generating a driving force in the optical axis (Z axis) direction. Since the aperture module 100 and the lens module 200 are disposed in the carrier 400, the carrier 400, the aperture module 100, and the lens module 200 may move together in the optical axis (Z axis) direction in response to the driving force generated by the focus adjustment unit 500.

[0151] The focus adjustment unit 500 may include a first magnet 510 and a first coil 530. The first magnet 510 and the first coil 530 may be disposed to face each other in a direction perpendicular to the optical axis (Z axis).

[0152] One of the first magnet 510 and the first coil 530 may be disposed on the carrier 400, and the other of the first magnet 510 and the first coil 530 may be disposed on the housing 300. In the following description, an embodiment in which the first magnet 510 is disposed on the carrier 400 and the first coil 530 is disposed on the housing 300 will be described.

[0153] The first magnet 510 may be mounted on the carrier 400. As an example, the first magnet 510 may be mounted on one side surface of the carrier 400.

[0154] The first magnet 510 may be magnetized so that one surface (e.g., a surface facing the first coil 530) may have both an N pole and an S pole. For example, one surface of the first magnet 510 facing the first coil 530 may include an N pole, a neutral region, and an S pole sequentially arranged in the optical axis (Z axis) direction.

[0155] The first coil 530 may be disposed to face the first magnet 510. For example, the first coil 530 may be disposed to face the first magnet 510 in a direction perpendicular to the optical axis (Z axis).

[0156] The first coil 530 may be disposed on the substrate 700, and the substrate 700 may be mounted on the housing 300 so that the first magnet 510 and the first coil 530 may face each other in a direction perpendicular to the optical axis (Z axis). As an example, the first coil 530 may be disposed on one surface of the substrate 700. The substrate 700 may be mounted on a side surface of the housing 300 so that the first magnet 510 and the first coil 530 may face each other in a direction perpendicular to the optical axis (Z axis).

[0157] The housing 300 may include an opening penetrating through a side surface of the housing 300 , and the first coil 530 disposed on the substrate 700 may directly face the first magnet 510 through the opening.

[0158] The first magnet 510 may be a moving member mounted on the carrier 400 and configured to move in the optical axis (Z-axis) direction together with the carrier 400 , and the first coil 530 may be a fixed member fixed to the substrate 700 .

[0159] When power is applied to the first coil 530 , the carrier 400 may move in the optical axis (Z-axis) direction in response to an electromagnetic force generated between the first magnet 510 and the first coil 530 .

[0160] Since the aperture module 100 and the lens module 200 are accommodated in the carrier 400 , the aperture module 100 and the lens module 200 may also move in the optical axis (Z-axis) direction together with the carrier 400 .

[0161] The first ball member B1 may be disposed between the bearing portion 400 and the housing 300. For example, the first ball member B1 may be disposed between the bearing portion 400 and the housing 300, and may reduce friction when the bearing portion 400 moves.

[0162] The first ball member B1 may include a plurality of balls arranged in the optical axis (Z axis) direction. When the bearing portion 400 moves in the optical axis (Z axis) direction, the plurality of balls may roll in the optical axis (Z axis) direction.

[0163] The first yoke 570 may be disposed on the housing 300. The first yoke 570 may be disposed at a position facing the first magnet 510. For example, the first coil 530 may be disposed on one surface of the substrate 700, and the first yoke 570 may be disposed on the other surface of the substrate 700 facing away from the one surface of the substrate 700.

[0164] The first magnet 510 and the first yoke 570 may generate an attractive force therebetween. For example, the first yoke 570 may be made of a magnetic material. The attractive force may act between the first magnet 510 and the first yoke 570 in a direction perpendicular to the optical axis (Z axis).

[0165] The first ball member B1 may maintain contact with each of the bearing portion 400 and the housing 300 by an attractive force acting between the first magnet 510 and the first yoke 570 .

[0166] The first guide groove 401 may be formed in each of the bearing portion 400 and the housing 300 .

[0167] For example, the first guide groove 401 may be formed in surfaces of the bearing portion 400 and the housing 300 that face each other.

[0168] The first guide groove 401 may extend in the optical axis (Z axis) direction. The first ball member B1 may be disposed in the first guide groove 401 .

[0169] The first ball member B1 may include a first ball group and a second ball group. The first ball group and the second ball group may be spaced apart from each other in a direction perpendicular to the optical axis (Z axis) (e.g., X axis direction). The first ball group may include a plurality of balls arranged along the optical axis (Z axis). The number of balls included in the second ball group may be different from the number of balls included in the first ball group.

[0170] For example, the first ball group may include two or more balls arranged along the optical axis (Z axis) direction, and the second ball group may include fewer balls than the number of balls included in the first ball group. The number of balls in each ball member may be changed as long as the number of balls in the first ball group is different from the number of balls in the second ball group.

[0171] In an implementation, the camera module 1 may sense the position of the carrier 400 in the optical axis (Z-axis) direction.

[0172] To this end, a first position sensor 550 may be provided. The first position sensor 550 may be disposed on the substrate 700 facing the first magnet 510. The first position sensor 550 may be a Hall sensor.

[0173] The camera module 1 can correct the shaking during imaging by moving the aperture module 100 and the lens module 200 in a direction perpendicular to the optical axis (Z axis). To this end, the camera module 1 may include an optical image stabilization unit 600 that moves the aperture module 100 and the lens module 200 in a direction perpendicular to the optical axis (Z axis).

[0174] In response to the driving force generated by the optical image stabilization unit 600 , the aperture module 100 and the lens module 200 may move together in a direction perpendicular to the optical axis (Z axis).

[0175] For example, the aperture module 100 and the lens module 200 may move together in a first axis (X axis) direction and a second axis (Y axis) direction.

[0176] The optical image stabilization unit 600 may include a first sub driving unit 610 and a second sub driving unit 630. The first sub driving unit 610 may generate a driving force in a first axis (X axis) direction, and the second sub driving unit 630 may generate a driving force in a second axis (Y axis) direction.

[0177] The first sub driving unit 610 may include a second magnet 611 and a second coil 613. The second magnet 611 and the second coil 613 may be disposed to face each other in the first axis (X axis) direction.

[0178] One of the second magnet 611 and the second coil 613 may be disposed on the aperture module 100, and the other of the second magnet 611 and the second coil 613 may be disposed on the housing 300. In the following description, an embodiment in which the second magnet 611 is disposed on the aperture module 100 will be described.

[0179] The second magnet 611 may be disposed on the aperture module 100. For example, the second magnet 611 may be mounted on the second side wall 114 (see Figure 3 )superior.

[0180] The second magnet 611 may be magnetized so that one surface (e.g., a surface facing the second coil 613) may have both an N pole and an S pole. For example, one surface of the second magnet 611 facing the second coil 613 may include an N pole, a neutral region, and an S pole sequentially arranged in the second axis (Y axis) direction. The second magnet 611 may have a shape having a length in the second axis (Y axis) direction.

[0181] The other surface of the second magnet 611, which faces away from the one surface of the second magnet 611, may be magnetized to have a polarity opposite to that of the one surface of the second magnet 611. For example, the other surface of the second magnet 611 may include an S pole, a neutral region, and an N pole sequentially arranged along the second axis (Y axis) direction, such that the N pole on the one surface is opposite to the S pole on the other surface, the neutral region on the one surface is opposite to the neutral region on the other surface, and the S pole on the one surface is opposite to the N pole on the other surface.

[0182] The second coil 613 may be disposed to face the second magnet 611. For example, the second coil 613 may be disposed to face the second magnet 611 in the first axis (X axis) direction.

[0183] The second coil 613 may include two coils arranged in the second axis (Y-axis) direction, and each of the two coils of the second coil 613 may have a ring shape having a central opening.

[0184] One of the two coils of the second coil 613 may be disposed to face the N pole of the one surface of the second magnet 611 , and the other of the two coils of the second coil 613 may be disposed to face the S pole of the one surface of the second magnet 611 .

[0185] Due to the polarity arrangement of the second magnet 611, magnetic field leakage can be prevented, so sufficient driving force can be generated even in the case of low power.

[0186] During optical image stabilization, the second magnet 611 may be a moving member mounted on the aperture module 100 , and the second coil 613 may be a fixed member fixed to the housing 300 .

[0187] When power is applied to the second coil 613 , the aperture module 100 and the lens module 200 may move in the first axis (X axis) direction in response to an electromagnetic force generated between the second magnet 611 and the second coil 613 .

[0188] The second magnet 611 and the second coil 613 may generate a driving force in a direction in which they face each other (eg, a first axis (X-axis) direction).

[0189] The second sub driving unit 630 may include a third magnet 631 and a third coil 633. The third magnet 631 and the third coil 633 may be disposed to face each other in the second axis (Y axis) direction.

[0190] One of the third magnet 631 and the third coil 633 may be disposed on the aperture module 100, and the other of the third magnet 631 and the third coil 633 may be disposed on the housing 300. In the following description, an embodiment in which the third magnet 631 is disposed on the aperture module 100 will be described.

[0191] The third magnet 631 may be disposed on the aperture module 100. For example, the third magnet 631 may be mounted on the third sidewall 115 of the base portion 110 of the aperture module 100.

[0192] The second side wall 114 and the third side wall 115 of the base portion 110 may be perpendicular to each other in a plane perpendicular to the optical axis (Z axis).

[0193] The third magnet 631 may be magnetized so that one surface (e.g., a surface facing the third coil 633) may have both an S pole and an N pole. For example, one surface of the third magnet 631 facing the third coil 633 may include an S pole, a neutral region, and an N pole sequentially arranged in the first axis (X axis) direction. The third magnet 631 may have a shape having a length in the first axis (X axis) direction.

[0194] The other surface of the third magnet 631, which faces away from the one surface of the third magnet 631, may be magnetized to have a polarity opposite to that of the one surface of the third magnet 631. For example, the other surface of the third magnet 631 may include an N pole, a neutral region, and an S pole sequentially arranged in the first axis (X axis) direction, such that the S pole on the one surface is opposite to the N pole on the other surface, the neutral region on the one surface is opposite to the neutral region on the other surface, and the N pole on the one surface is opposite to the S pole on the other surface.

[0195] The third coil 633 may be disposed to face the third magnet 631. For example, the third coil 633 may be disposed to face the third magnet 631 in the second axis (Y axis) direction.

[0196] The third coil 633 may include two coils arranged in the first axis (X axis) direction, and each of the two coils of the third coil 633 may have a ring shape having a central opening.

[0197] One of the two coils of the third coil 633 may be disposed to face the S pole of the one surface of the third magnet 631 , and the other of the two coils of the third coil 633 may be disposed to face the N pole of the one surface of the third magnet 631 .

[0198] Due to the polarity arrangement of the third magnet 631, magnetic field leakage can be prevented, so sufficient driving force can be generated even in the case of low power.

[0199] The second coil 613 and the third coil 633 may be disposed on the substrate 700. As an example, the second coil 613 and the third coil 633 may be disposed on the substrate 700 facing the second magnet 611 and the third magnet 631.

[0200] The substrate 700 may be mounted on a side surface of the housing 300 , and the second coil 613 and the third coil 633 may directly face the second magnet 611 and the third magnet 631 through an opening in the housing 300 .

[0201] During optical image stabilization, the third magnet 631 may be a moving member mounted on the aperture module 100 , and the third coil 633 may be a fixed member fixed to the housing 300 .

[0202] When power is applied to the third coil 633 , the aperture module 100 and the lens module 200 may move in the second axis (Y-axis) direction in response to an electromagnetic force generated between the third magnet 631 and the third coil 633 .

[0203] The third magnet 631 and the third coil 633 may generate a driving force in a direction in which they face each other (eg, a second axis (Y-axis) direction).

[0204] The second magnet 611 and the third magnet 631 may be disposed perpendicularly to each other in a plane perpendicular to the optical axis (Z axis), and the second coil 613 and the third coil 633 may also be disposed perpendicularly to each other in a plane perpendicular to the optical axis (Z axis).

[0205] Generally, in the prior art, a magnet for optical image stabilization has been mounted on the lens module 200. In this case, it is necessary to provide the lens module 200 with a lens holder on which the magnet for optical image stabilization is mounted.

[0206] However, in this embodiment, the second magnet 611 and the third magnet 631 of the optical image stabilization unit 600 may be coupled to the aperture module 100, so that a lens holder is not required. Therefore, the size and weight of the camera module 1 may be reduced.

[0207] The camera module 1 according to the embodiment may include a second ball member B2 supporting the aperture module 100. The second ball member B2 may play a role in guiding the movement of the aperture module 100 during optical image stabilization and may also play a role in maintaining a predetermined distance between the aperture module 100 and the carrier 400.

[0208] The second ball member B2 may guide the aperture module 100 to move in the first axis (X axis) direction and the second axis (Y axis) direction.

[0209] As an example, when a driving force in the first axis (X axis) direction is generated, the second ball member B2 may roll in the first axis (X axis) direction. Therefore, the second ball member B2 may guide the movement of the aperture module 100 in the first axis (X axis) direction.

[0210] When a driving force in the second axis (Y axis) direction is generated, the second ball member B2 may roll in the second axis (Y axis) direction. Therefore, the second ball member B2 may guide the movement of the aperture module 100 in the second axis (Y axis) direction.

[0211] The second ball member B2 may include a plurality of ball members disposed between the aperture module 100 and the carrier 400. For example, the second ball member B2 may include four ball members.

[0212] The second guide groove 402 accommodating the second ball member B2 may be formed in one or both of the surface of the aperture module 100 and the surface of the bearing portion 400 facing each other in the optical axis (Z axis) direction. The second guide groove 402 may include a plurality of guide grooves corresponding to the plurality of ball members of the second ball member B2.

[0213] The second ball member B2 may be received in the second guide groove 402 and may be inserted into a region between the aperture module 100 and the carrier 400 .

[0214] The size of the second guide groove 402 may be larger than the diameter of the second ball member B2. The planar shape of the second guide groove 402 may be circular or polygonal.

[0215] In an embodiment, the camera module 1 may sense the position of the aperture module 100 in a direction perpendicular to the optical axis (Z axis).

[0216] To this end, a second position sensor 615 and a third position sensor 635 may be provided. The second position sensor 615 may be disposed on the substrate 700 facing the second magnet 611, and the third position sensor 635 may be disposed on the substrate 700 facing the third magnet 631. The second position sensor 615 and the third position sensor 635 may be Hall sensors.

[0217] One or both of the second position sensor 615 and the third position sensor 635 may include two Hall sensors. For example, the third position sensor 635 may include two Hall sensors disposed to face the third magnet 631.

[0218] Whether the aperture module 100 rotates may be sensed by two Hall sensors facing the third magnet 631. Since the third coil 633 includes two coils facing the third magnet 631, the rotational force applied to the aperture module 100 may be offset by controlling the two coils of the third coil 633.

[0219] In an embodiment, a second yoke 421 and a third yoke 422 may be provided so that the aperture module 100 and the carrier 400 may maintain contact with the second ball member B2 .

[0220] The second yoke 421 and the third yoke 422 may be mounted on the carrier 400 , and may be disposed to face the second magnet 611 and the third magnet 631 , respectively, in the optical axis (Z-axis) direction.

[0221] Therefore, an attractive force may be generated between the second yoke 421 and the second magnet 611 in the optical axis (Z axis) direction, and an attractive force may be generated between the third yoke 422 and the third magnet 631 in the optical axis (Z axis) direction.

[0222] Since the aperture module 100 is pressed in a direction toward the second yoke 421 and the third yoke 422 by an attractive force generated between the second yoke 421 and the second magnet 611 and an attractive force generated between the third yoke 422 and the third magnet 631 , the aperture module 100 may maintain contact with the second ball member B2 .

[0223] The second yoke 421 and the third yoke 422 may be made of a material that respectively generates attractive forces with the second magnet 611 and the third magnet 631. As an example, the second yoke 421 and the third yoke 422 may be made of a magnetic material.

[0224] The stopper 430 may be coupled to the carrier 400. The stopper 430 may be coupled to the carrier 400 to cover at least a portion of an upper surface of the aperture module 100.

[0225] The stopper 430 may prevent the aperture module 100 from being separated from the carrier 400 due to external impact.

[0226] Despite Figure 1 Although not shown in the drawing, a buffer member having elastic force may be coupled to an edge portion of the stopper 430 .

[0227] Figure 4 is an exploded perspective view showing a camera module according to another embodiment of the present disclosure.

[0228] Reference Figure 4 , with reference Figures 1 to 3 Compared with the camera module 1, Figure 4 The camera module 2 shown in FIG. 4 may also include a guide frame 410. Figure 4 A portion of the camera module 2 related to the guide frame 410 is described.

[0229] The guide frame 410 may be disposed between the aperture module 100 and the carrier 400. The guide frame 410 may play a role in guiding the aperture module 100 to move in a direction perpendicular to the optical axis (Z-axis) direction.

[0230] The guide frame 410 and the aperture module 100 may be sequentially stacked in the carrier 400. For example, the guide frame 410 may be disposed between the carrier 400 and the aperture module 100. The guide frame 410 may have a quadrangular plate shape having a central opening.

[0231] The guide frame 410 and the aperture module 100 can move together in one direction perpendicular to the optical axis (Z axis) in response to a driving force generated by the optical image stabilization unit 600, and the aperture module 100 can move relative to the guide frame 410 in another direction perpendicular to the optical axis (Z axis) in response to another driving force generated by the optical image stabilization unit 600.

[0232] For example, the guide frame 410 and the aperture module 100 can move together in a first axis (X axis) direction perpendicular to the optical axis (Z axis) in response to a driving force generated by the optical image stabilization unit 600 in the first axis (X axis) direction, and the aperture module 100 can move relative to the guide frame 410 in a second axis (Y axis) direction in response to another driving force generated by the optical image stabilization unit 600 in the second axis (Y axis) direction.

[0233] The second ball member B2 may be disposed between the guide frame 410 and the bearing portion 400 , and the third ball member B3 may be disposed between the aperture module 100 and the guide frame 410 .

[0234] The second ball member B2 may guide the movement of the aperture module 100 and the guide frame 410 in the first axis (X axis) direction, and the third ball member B3 may guide the movement of the aperture module 100 in the second axis (Y axis) direction.

[0235] The second ball member B2 may include a plurality of ball members disposed between the guide frame 410 and the carrier 400 , and the third ball member B3 may include a plurality of ball members disposed between the aperture module 100 and the guide frame 410 .

[0236] For example, each of the second ball member B2 and the third ball member B3 may include four ball members.

[0237] The second guide groove 402 accommodating the second ball member B2 may be formed in one or both of a surface of the guide frame 410 and a surface of the bearing portion 400 facing each other in the optical axis (Z-axis) direction.

[0238] The second ball member B2 may be received in the second guide groove 402 and may be inserted into a region between the bearing portion 400 and the guide frame 410 .

[0239] When the second ball member B2 is accommodated in the second guide groove 402, the movement of the second ball member B2 in the optical axis (Z axis) and the second axis (Y axis) direction can be restricted, and the second ball member B2 can move only in the first axis (X axis) direction. For example, the second ball member B2 can roll only in the first axis (X axis) direction.

[0240] To this end, the planar shape of the second guide groove 402 may be a rectangular shape having a length in the first axis (X axis) direction.

[0241] The third guide groove 403 accommodating the third ball member B3 may be formed in one or both of a surface of the aperture module 100 and a surface of the guide frame 410 facing each other in the optical axis (Z-axis) direction.

[0242] The third ball member B3 may be received in the third guide groove 403 and may be inserted into a region between the aperture module 100 and the guide frame 410 .

[0243] When the third ball member B3 is accommodated in the third guide groove 403, the movement of the third ball member B3 in the optical axis (Z axis) and the first axis (X axis) direction can be restricted, and the third ball member B3 can move only in the second axis (Y axis) direction. For example, the third ball member B3 can roll only in the second axis (Y axis) direction.

[0244] To this end, the planar shape of the third guide groove 403 may be a rectangular shape having a length in the second axis (Y-axis) direction.

[0245] When a driving force is generated in the first axis (X axis) direction, the aperture module 100 and the guide frame 410 may move together in the first axis (X axis) direction.

[0246] In this case, the second ball member B2 can roll only along the first axis (X axis) direction. In this case, the movement of the third ball member B3 can be restricted.

[0247] In addition, when a driving force is generated in the second axis (Y axis) direction, the aperture module 100 may move in the second axis (Y axis) direction relative to the guide frame 410 .

[0248] In this case, the third ball member B3 can roll only along the second axis (Y axis) direction. In this case, the movement of the second ball member B2 can be restricted.

[0249] Figure 5 is an exploded perspective view showing a camera module according to another embodiment of the present disclosure. Figure 6 It is shown Figure 5 A perspective view of an aperture module of a camera module.

[0250] Reference Figure 5 , with reference Figures 1 to 3 Compared with the camera module 1, Figure 5 The camera module 3 shown in FIG. 1 may have differences in the lens module 200, the aperture module 100 and the optical image stabilization unit 600. Figure 5Portions of the camera module 3 related to the lens module 200 , the aperture module 100 , and the optical image stabilization unit 600 are described.

[0251] The lens module 200 may be disposed in the aperture module 100. For example, the lens module 200 may be disposed in an inner space of the base part 110 of the aperture module 100.

[0252] That is, the aperture module 100 may be disposed in front of the lens module 200 .

[0253] In addition, the second magnet 611 and the third magnet 631 may be disposed on the aperture module 100. For example, the second magnet 611 and the third magnet 631 may be disposed on the base portion 110 of the aperture module 100.

[0254] The bottom surface of the second magnet 611 and the bottom surface of the third magnet 631 may be disposed at a position lower than the bottom surface of the aperture magnet 174 in the optical axis (Z-axis) direction.

[0255] To this end, the first extension portion 114a extending in the optical axis (Z axis) direction can be attached to the second side wall 114 of the base portion 110, and the second extension portion 115a extending in the optical axis (Z axis) direction can be attached to the third side wall 115 of the base portion 110.

[0256] The second magnet 611 may be disposed on the first extending portion 114 a , and the third magnet 631 may be disposed on the second extending portion 115 a .

[0257] Reference Figure 5 ,and Figures 1 to 3 Compared with the camera module 1 in FIG. 1 , since the aperture module 100 is disposed in front of the lens module 200 , the second magnet 611 and the third magnet 631 mounted on the aperture module 100 may need to be disposed at a lower position in the optical axis (Z-axis) direction.

[0258] Figure 7 is an exploded perspective view showing a camera module according to another embodiment of the present disclosure. Figure 8 It is shown Figure 7 A perspective view of a portion of a camera module. Fig. 9 It is shown Figure 7 and Figure 8 A three-dimensional diagram of the aperture module and the OIS bearing part. Fig. 10A It is shown Figures 7 to 9 A plan view of a first substrate. Fig. 10B It is shown Figures 7 to 9 A three-dimensional view of a first substrate.

[0259] Reference Figures 7 to 10BAccording to another embodiment, the camera module 4 may include an aperture module 100, a lens module 200 (for example, see Figure 1 ) and shell 300.

[0260] The aperture module 100 may be disposed in the housing 300 , and may control the amount of light incident to the camera module 4 .

[0261] The lens module 200 may be coupled to the aperture module 100. The lens module 200 may include a first lens unit 210 and a second lens unit 230 spaced apart from each other in the optical axis (Z axis) direction. The first lens unit 210 may include one or more lenses, and the second lens unit 230 may include a plurality of lenses.

[0262] The aperture module 100 may be disposed between the first lens unit 210 and the second lens unit 230. For example, the first lens unit 210 may be coupled to an upper portion of the aperture module 100, and the second lens unit 230 may be coupled to a lower portion of the aperture module 100.

[0263] The aperture module 100 and the lens module 200 may be coupled to each other and may move together.

[0264] That is, the aperture module 100 and the lens module 200 can move together in the optical axis (Z axis) direction for focus adjustment. In addition, the aperture module 100 and the lens module 200 can move together in a direction perpendicular to the optical axis (Z axis) for optical image stabilization.

[0265] The camera module 4 may further include an OIS carrier 4000 , a guide frame 4100 , a housing 310 , and an image sensor module 800 .

[0266] The OIS carrier 4000 and the guide frame 4100 may be disposed in the housing 300 , and may be movable relative to the housing 300 in a direction perpendicular to the optical axis (Z-axis) direction.

[0267] The housing 300 may have a shape in which upper and lower portions are opened, the OIS carrier 4000 and the guide frame 4100 may be disposed in an inner space of the housing 300 , and the aperture module 100 and the lens module 200 may be accommodated in the OIS carrier 4000 .

[0268] The OIS carrier 4000, the lens module 200, and the aperture module 100 can move together in a direction perpendicular to the optical axis (Z-axis) direction. Therefore, it is possible to correct shaking during imaging.

[0269] In addition, the lens module 200 and the aperture module 100 may move together in the optical axis (Z axis) direction in the OIS carrier 4000. Therefore, the distance between the lens module 200 and the image sensor 810 may be changed to adjust the focus of the camera module 4.

[0270] The camera module 4 may include an actuator driving unit. The actuator driving unit may generate a driving force in one or more directions of the optical axis (Z axis), the first axis (X axis), and the second axis (Y axis). The actuator driving unit may include one or more magnets and one or more coils.

[0271] For example, the actuator driving unit may include a focus adjustment unit 500 (see, for example, Figure 1 ) and an optical image stabilization unit 600 (see, for example, Figure 1 ), wherein the focus adjustment unit 500 generates a driving force in the optical axis (Z-axis) direction, and the optical image stabilization unit 600 generates a driving force in a direction perpendicular to the optical axis (Z-axis) direction.

[0272] The image sensor module 800 may be a device that converts incident light passing through the lens module 200 into an electrical signal.

[0273] As an example, the image sensor module 800 may include an image sensor 810 and a printed circuit board 830 to which the image sensor 810 is connected, and may further include an infrared cut filter (not shown).

[0274] The infrared cut filter may block light in an infrared region among light incident through the lens module 200 .

[0275] The image sensor 810 may convert incident light passing through the lens module 200 into an electrical signal. As an example, the image sensor 810 may be a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS) device.

[0276] The electrical signal converted by the image sensor 810 may be output as an image through a display unit of a portable electronic device in which the camera module 4 is installed.

[0277] The image sensor 810 may be fixed to the printed circuit board 830 and may be electrically connected to the printed circuit board 830 through wire bonding.

[0278] The image sensor module 800 may be disposed in a lower portion of the housing 300 .

[0279] The housing 310 may be coupled to the case 300 to surround an outer surface of the case 300 , and may play a role in protecting internal components of the camera module 4 .

[0280] The focus adjustment unit 500 may move the aperture module 100 and the lens module 200 to focus on the object. For example, the focus adjustment unit 500 may move the aperture module 100 by generating a driving force in the optical axis (Z axis) direction. Since the aperture module 100 is coupled to the lens module 200, the aperture module 100 and the lens module 200 may move together in the optical axis (Z axis) direction in response to the driving force generated by the focus adjustment unit 500.

[0281] The focus adjustment unit 500 may include a first magnet 510 and a first coil 530. The first magnet 510 and the first coil 530 may be disposed to face each other in a direction perpendicular to the optical axis (Z axis).

[0282] One of the first magnet 510 and the first coil 530 may be disposed on the aperture module 100, and the other of the first magnet 510 and the first coil 530 may be disposed on the OIS carrier 4000. In the following description, an embodiment in which the first magnet 510 is disposed on the aperture module 100 may be described.

[0283] The first magnet 510 may be mounted on the aperture module 100. As an example, the first magnet 510 may be mounted on the base portion 110 of the aperture module 100 (eg, see Figure 2 ) on one side surface.

[0284] The first magnet 510 may be magnetized so that one surface (e.g., a surface facing the first coil 530) may have both an N pole and an S pole. For example, one surface of the first magnet 510 facing the first coil 530 may include an N pole, a neutral region, and an S pole sequentially arranged in the optical axis (Z axis) direction.

[0285] The first coil 530 may be disposed to face the first magnet 510. For example, the first coil 530 may be disposed to face the first magnet 510 in a direction perpendicular to the optical axis (Z axis).

[0286] The first coil 530 may be disposed on the first substrate 7300, and the first substrate 7300 may be mounted on the OIS carrier 4000 so that the first magnet 510 and the first coil 530 may face each other in a direction perpendicular to the optical axis (Z axis). As an example, the first coil 530 may be disposed on one surface of the first substrate 7300. The first substrate 7300 may be mounted on a side surface of the OIS carrier 4000 so that the first magnet 510 and the first coil 530 may face each other in a direction perpendicular to the optical axis (Z axis).

[0287] The OIS carrier 4000 may include an opening penetrating a side surface of the OIS carrier 4000 , and the first coil 530 disposed on the first substrate 7300 may directly face the first magnet 510 through the opening.

[0288] The first magnet 510 may be a moving member mounted on the aperture module 100 and moving in the optical axis (Z-axis) direction together with the aperture module 100 , and the first coil 530 may be a fixed member fixed to the first substrate 7300 .

[0289] When power is applied to the first coil 530 , the aperture module 100 may move in the optical axis (Z-axis) direction in response to an electromagnetic force generated between the first magnet 510 and the first coil 530 .

[0290] Since the aperture module 100 is coupled to the lens module 200 , the lens module 200 may also move in the optical axis (Z-axis) direction together with the aperture module 100 .

[0291] Generally, in the prior art, a magnet for focus adjustment may be mounted on an auto focus (AF) bearing portion. However, in this embodiment, the first magnet 510 of the focus adjustment unit 500 may be mounted on the aperture module 100, thereby eliminating the need for an additional component such as an AF bearing portion. Therefore, the size and weight of the camera module 4 may be reduced.

[0292] The first ball member B1 may be disposed between the aperture module 100 and the OIS carrier 4000. For example, the first ball member B1 may be disposed between the aperture module 100 and the OIS carrier 4000 to reduce friction when the aperture module 100 moves in the optical axis (Z axis) direction.

[0293] The first ball member B1 may include a plurality of balls arranged along the optical axis (Z axis) direction. When the aperture module 100 moves in the optical axis (Z axis) direction, the plurality of balls may roll in the optical axis (Z axis) direction.

[0294] The first yoke 570 may be disposed on the housing 300. The first yoke 570 may be disposed at a position facing the first magnet 510. For example, the first coil 530 may be disposed on one surface of the first substrate 7300, and the first yoke 570 may be disposed on another surface of the first substrate 7300.

[0295] The first magnet 510 and the first yoke 570 may generate an attractive force therebetween. For example, the first yoke 570 may be made of a magnetic material. The attractive force may act between the first magnet 510 and the first yoke 570 in a direction perpendicular to the optical axis (Z axis).

[0296] The first ball member B1 may maintain contact with each of the aperture module 100 and the OIS carrier 4000 by an attractive force acting between the first magnet 510 and the first yoke 570 .

[0297] The first guide groove 4010 may be formed in each of the aperture module 100 and the OIS carrier 4000 .

[0298] For example, the first guide groove 4010 may be formed in surfaces of the OIS carrier 4000 and the base portion 110 of the aperture module 100 that face each other.

[0299] The first guide groove 4010 may extend in the optical axis (Z axis) direction. The first ball member B1 may be disposed in the first guide groove 4010.

[0300] The first ball member B1 may include a first ball group and a second ball group. The first ball group and the second ball group may be spaced apart from each other in a direction perpendicular to the optical axis (Z axis) (e.g., Y axis direction). The first ball group may include a plurality of balls arranged along the optical axis (Z axis). The number of balls included in the second ball group may be different from the number of balls included in the first ball group.

[0301] For example, the first ball group may include two or more balls arranged along the optical axis (Z axis) direction, and the second ball group may include fewer balls than the number of balls included in the first ball group. The number of balls in each ball member may be changed as long as the number of balls in the first ball group is different from the number of balls in the second ball group.

[0302] In an implementation, the camera module 4 may sense the position of the aperture module 100 in the optical axis (Z-axis) direction.

[0303] To this end, a first position sensor 550 may be provided. The first position sensor 550 may be disposed on the first substrate 7300 facing the first magnet 510. The first position sensor 550 may be a Hall sensor.

[0304] The camera module 4 can correct the shaking during imaging by moving the OIS carrier 4000 in a direction perpendicular to the optical axis (Z axis). To this end, the camera module 4 may include an optical image stabilization unit 600 configured to move the OIS carrier 4000 in a direction perpendicular to the optical axis (Z axis).

[0305] The guide frame 4100 and the OIS carrier 4000 may be stacked in sequence in the housing 300. For example, the guide frame 4100 may be disposed between the OIS carrier 4000 and the housing 300. When viewed in the optical axis (Z axis) direction, the guide frame 4100 may have a shape in which both sides of the quadrilateral shape are removed. For example, when viewed in the optical axis (Z axis) direction, the guide frame 4100 may have a "┓" shape or a "┗" shape.

[0306] In response to the driving force generated by the optical image stabilization unit 600, the guide frame 4100 and the OIS carrier 4000 can move together in one direction perpendicular to the optical axis (Z axis), and the OIS carrier 4000 can move relative to the guide frame 4100 in another direction perpendicular to the optical axis (Z axis).

[0307] For example, the guide frame 4100 and the OIS carrier 4000 may move together in a first axis (X axis) direction perpendicular to the optical axis (Z axis), and the OIS carrier 4000 may move relative to the guide frame 4100 in a second axis (Y axis) direction.

[0308] Since the aperture module 100 and the lens module 200 are disposed in the OIS carrier 4000 , the aperture module 100 and the lens module 200 may move together with the OIS carrier 4000 .

[0309] For example, the OIS carrier 4000 , the aperture module 100 , and the lens module 200 may move together in a first axis (X axis) direction and a second axis (Y axis) direction.

[0310] The optical image stabilization unit 600 may include a first sub-driving unit 610 (eg, see Figure 1 ) and the second sub-drive unit 630 (see, for example, Figure 1 ). The first sub driving unit 610 may generate a driving force in a first axis (X axis) direction, and the second sub driving unit 630 may generate a driving force in a second axis (Y axis) direction.

[0311] The first sub driving unit 610 may include a second magnet 611 and a second coil 613. The second magnet 611 and the second coil 613 may be disposed to face each other in the first axis (X axis) direction.

[0312] One of the second magnet 611 and the second coil 613 may be disposed on the OIS carrier 4000, and the other of the second magnet 611 and the second coil 613 may be disposed on the housing 300. In the following description, an embodiment in which the second magnet 611 is disposed on the OIS carrier 4000 will be described.

[0313] The second magnet 611 may be disposed on the OIS carrier 4000. For example, the second magnet 611 may be mounted on one side surface of the OIS carrier 4000.

[0314] The second magnet 611 may be magnetized such that one surface (eg, a surface facing the second coil 613) of the second magnet 611 may have an N pole or an S pole. The second magnet 611 may have a shape having a length in the second axis (Y axis) direction.

[0315] The other surface of the second magnet 611, which faces away from the one surface of the second magnet 611, may be magnetized to have a polarity opposite to that of the one surface of the second magnet 611. For example, if the one surface of the second magnet 611 has an N pole, the other surface of the second magnet 611 may have an S pole. Alternatively, if the one surface of the second magnet 611 has an S pole, the other surface of the second magnet 611 may have an N pole.

[0316] The second coil 613 may be disposed to face the second magnet 611. For example, the second coil 613 may be disposed to face the second magnet 611 in the first axis (X axis) direction.

[0317] The second coil 613 may include one coil, and may have a ring shape having a central opening.

[0318] During optical image stabilization, the second magnet 611 may be a moving member mounted on the OIS carrier 4000 , and the second coil 613 may be a fixed member fixed to the housing 300 .

[0319] When power is applied to the second coil 613 , the OIS carrier 4000 and the guide frame 4100 may move in the first axis (X axis) direction in response to an electromagnetic force generated between the second magnet 611 and the second coil 613 .

[0320] The second magnet 611 and the second coil 613 may generate a driving force in a direction in which they face each other (eg, a first axis (X-axis) direction).

[0321] The second sub driving unit 630 may include a third magnet 631 and a third coil 633. The third magnet 631 and the third coil 633 may be disposed to face each other in the second axis (Y axis) direction.

[0322] One of the third magnet 631 and the third coil 633 may be disposed on the OIS carrier 4000, and the other of the third magnet 631 and the third coil 633 may be disposed on the housing 300. In the following description, an embodiment in which the third magnet 631 is disposed on the OIS carrier 4000 will be described.

[0323] The third magnet 631 may be disposed on the OIS carrier 4000. For example, the third magnet 631 may be mounted on the other side surface of the OIS carrier 4000 adjacent to one side surface of the OIS carrier 4000 on which the second magnet 611 is mounted.

[0324] One side surface of the OIS carrier 4000 on which the second magnet 611 is mounted and the other side surface of the OIS carrier 4000 on which the third magnet 631 is mounted may be perpendicular to each other on a plane perpendicular to the optical axis (Z axis).

[0325] The third magnet 631 may be magnetized such that one surface (eg, a surface facing the third coil 633) of the third magnet 631 may have an N pole or an S pole. The third magnet 631 may have a shape having a length in the first axis (X axis) direction.

[0326] The other surface of the third magnet 631, which faces away from the one surface of the third magnet 631, may be magnetized to have a polarity opposite to that of the one surface of the third magnet 631. For example, if the one surface of the third magnet 631 has an N pole, the other surface of the third magnet 631 may have an S pole. Alternatively, if the one surface of the third magnet 631 has an S pole, the other surface of the third magnet 631 may have an N pole.

[0327] The third coil 633 may be disposed to face the third magnet 631. For example, the third coil 633 may be disposed to face the third magnet 631 in the second axis (Y axis) direction.

[0328] The third coil 633 may include one coil, and may have a ring shape having a central opening.

[0329] The second coil 613 and the third coil 633 may be disposed on the second substrate 7100. As an example, the second coil 613 and the third coil 633 may be disposed on the second substrate 7100 facing the second magnet 611 and the third magnet 631.

[0330] The second substrate 7100 may be mounted on both side surfaces of the housing 300 , and the second coil 613 and the third coil 633 may directly face the second magnet 611 and the third magnet 631 through two openings provided in the housing 300 .

[0331] During optical image stabilization, the third magnet 631 may be a moving member mounted on the OIS carrier 4000 , and the third coil 633 may be a fixed member fixed to the housing 300 .

[0332] When power is applied to the third coil 633 , the OIS carrier 4000 may move in the second axis (Y axis) direction in response to an electromagnetic force generated between the third magnet 631 and the third coil 633 .

[0333] The third magnet 631 and the third coil 633 may generate a driving force in a direction in which they face each other (eg, a second axis (Y-axis) direction).

[0334] The second magnet 611 and the third magnet 631 may be disposed perpendicularly to each other on a plane perpendicular to the optical axis (Z axis), and the second coil 613 and the third coil 633 may also be disposed perpendicularly to each other on a plane perpendicular to the optical axis (Z axis).

[0335] The camera module 4 may include a plurality of ball bearing members supporting the guide frame 4100 and the OIS carrier 4000. The plurality of ball bearing members may play a role in guiding the movement of the OIS carrier 4000 and the guide frame 4100 during optical image stabilization, and may also play a role in maintaining a predetermined distance between the housing 300 and the guide frame 4100 and a predetermined distance between the guide frame 4100 and the OIS carrier 4000.

[0336] The plurality of ball members may include a second ball member B2 and a third ball member B3.

[0337] The second ball member B2 may guide the movement of the guide frame 4100 and the OIS carrier 4000 in the first axis (X axis) direction, and the third ball member B3 may guide the movement of the OIS carrier 4000 in the second axis (Y axis) direction.

[0338] As an example, when a driving force is generated in the first axis (X axis) direction, the second ball member B2 may roll in the first axis (X axis) direction. Therefore, the second ball member B2 may guide the movement of the guide frame 4100 and the OIS carrier 4000 in the first axis (X axis) direction.

[0339] When a driving force is generated in the second axis (Y axis) direction, the third ball member B3 may roll in the second axis (Y axis) direction. Therefore, the third ball member B3 may guide the movement of the OIS carrier 4000 in the second axis (Y axis) direction.

[0340] The second ball member B2 may include a plurality of ball members disposed between the housing 300 and the guide frame 4100 , and the third ball member B3 may include a plurality of ball members disposed between the guide frame 4100 and the OIS carrier 4000 .

[0341] For example, each of the second ball member B2 and the third ball member B3 may include three ball members.

[0342] The second guide groove 4110 accommodating the second ball member B2 may be formed in one or both of the surface of the housing 300 and the surface of the guide frame 4100 facing each other in the optical axis (Z axis) direction. The second guide groove 4110 may include a plurality of grooves corresponding to the plurality of ball members of each second ball member B2.

[0343] The second ball member B2 may be received in the second guide groove 4110 and may be inserted into a region between the housing 300 and the guide frame 4100 .

[0344] When the second ball member B2 is accommodated in the second guide groove 4110, the movement of the second ball member B2 in the optical axis (Z axis) direction and the second axis (Y axis) direction can be restricted, and the second ball member B2 can move only in the first axis (X axis) direction. For example, the second ball member B2 can roll only in the first axis (X axis) direction.

[0345] To this end, a planar shape of each of the plurality of grooves of the second guide groove 4110 may be a rectangular shape having a length in the first axis (X axis) direction.

[0346] The third guide groove 4120 accommodating the third ball member B3 may be formed in one or both of the surfaces of the guide frame 4100 and the OIS carrier 4000 facing each other in the optical axis (Z axis) direction. The third guide groove 4120 may include a plurality of grooves corresponding to the plurality of ball members of the third ball member B3.

[0347] The third ball member B3 may be received in the third guide groove 4120 and may be inserted into a region between the guide frame 4100 and the OIS carrier 4000 .

[0348] When the third ball member B3 is accommodated in the third guide groove 4120, the movement of the third ball member B3 in the optical axis (Z axis) direction and the first axis (X axis) direction can be restricted, and the third ball member B3 can move only in the second axis (Y axis) direction. For example, the third ball member B3 can roll only in the second axis (Y axis) direction.

[0349] To this end, a planar shape of each of the plurality of grooves of the third guide groove 4120 may be a rectangular shape having a length in the second axis (Y axis) direction.

[0350] When a driving force is generated in the first axis (X axis) direction, the guide frame 4100 and the OIS carrier 4000 can move together in the first axis (X axis) direction. In addition, the aperture module 100 and the lens module 200 can also move together with the OIS carrier 4000 in the first axis (X axis) direction.

[0351] In this case, the second ball member B2 can roll along the first axis (X axis) direction, and the movement of the third ball member B3 can be restricted.

[0352] In addition, when a driving force is generated in the second axis (Y axis) direction, the OIS carrier 4000 can move in the second axis (Y axis) direction relative to the guide frame 4100. In addition, the aperture module 100 and the lens module 200 can also move in the second axis (Y axis) direction together with the OIS carrier 4000.

[0353] In this case, the third ball member B3 can roll along the second axis (Y axis) direction and can restrict the movement of the second ball member B2.

[0354] In an implementation, the camera module 4 may sense the position of the aperture module 100 in a direction perpendicular to the optical axis (Z axis).

[0355] To this end, a second position sensor 615 and a third position sensor 635 may be provided. The second position sensor 615 may be disposed on the second substrate 7100 facing the second magnet 611, and the third position sensor 635 may be disposed on the second substrate 7100 facing the third magnet 631. The second position sensor 615 and the third position sensor 635 may be Hall sensors.

[0356] In an embodiment, the second yoke 301 and the third yoke 302 may be provided so that the housing 300 and the guide frame 4100 may maintain contact with the second ball member B2, and the guide frame 4100 and the OIS carrier 4000 may maintain contact with the third ball member B3.

[0357] The second yoke 301 and the third yoke 302 may be fixed to the housing 300 , and may be disposed to face the second magnet 611 and the third magnet 631 in the optical axis (Z-axis) direction.

[0358] Therefore, an attractive force can be generated in the optical axis (Z-axis) direction between the second yoke 301 and the second magnet 611 and between the third yoke 302 and the third magnet 631 .

[0359] Since the OIS bearing part 4000 and the guide frame 4100 are pressed in the direction toward the second yoke 301 and the third yoke 302 by the attraction generated between the second yoke 301 and the second magnet 611 and between the third magnet 631 and the third yoke 302, the OIS bearing part 4000 and the guide frame 4100 can maintain contact with the second ball member B2 and the third ball member B3.

[0360] The second yoke 301 and the third yoke 302 may be made of a material that can respectively generate attractive forces with the second magnet 611 and the third magnet 631. As an example, the second yoke 301 and the third yoke 302 may be made of a magnetic material.

[0361] The stopper 450 may be coupled to the OIS carrier 4000 . The stopper 450 may be coupled to the OIS carrier 4000 to cover at least a portion of an upper surface of the aperture module 100 .

[0362] The stopper 450 may prevent the aperture module 100 from being separated from the OIS carrier 4000 due to external impact.

[0363] Despite Figure 7 Although not shown in the drawing, a buffer member having elastic force may be coupled to an edge portion of the stopper 450 .

[0364] The aperture drive unit 170 (see, for example, Figure 2 ) may include an aperture magnet 174 and an aperture coil 175. The aperture magnet 174 may be disposed on the aperture module 100. The aperture coil 175 of the aperture driving unit 170, the aperture position sensor 176, and the first coil 530 of the focus adjustment unit 500 may be disposed on the first substrate 7300.

[0365] Since the first substrate 7300 is mounted on the OIS carrier 4000, the first substrate 7300 may move together with the OIS carrier 4000 during optical image stabilization. Since the first substrate 7300 moves during optical image stabilization, components for stably supplying power to the aperture coil 175 and the first coil 530 may be necessary.

[0366] To this end, the first substrate 7300 may include a first mounting unit 7310, a second mounting unit 7320, an extension portion 7330, and a fixing portion 7340. The first coil 530 may be disposed on the first mounting unit 7310, and the aperture coil 175 may be disposed on the second mounting unit 7320. The second mounting unit 7320 may be bent and extend from one end of the first mounting unit 7310.

[0367] The extension portion 7330 may be configured to connect the first mounting unit 7310 to the fixing portion 7340. For example, one end of the extension portion 7330 may be connected to the other end of the first mounting unit 7310, and the other end of the extension portion 7330 may be connected to the fixing portion 7340. The extension portion 7330 may have a curved shape, may be bent at least once, and may be made of a flexible material.

[0368] The fixing portion 7340 may be connected to the printed circuit board 830 , and may supply power to the first substrate 7300 .

[0369] The first mounting unit 7310 and the second mounting unit 7320 may be mounted on the side surface of the OIS carrier 4000, and the fixing portion 7340 may be mounted on the side surface of the housing 300. In addition, a first portion of the extension portion 7330 may extend along the side surface of the OIS carrier 4000, and a second portion of the extension portion 7330 may be mounted on the side surface of the housing 300 on which the fixing portion 7340 is mounted.

[0370] That is, the second portion of the extending portion 7330 may be disposed on the housing 300 , and the first portion of the extending portion 7330 may not be disposed on the housing 300 .

[0371] A portion of the extension portion 7330 may be spaced apart from a side surface of the OIS carrier 4000 in a direction perpendicular to the optical axis (Z axis).

[0372] The side surface of the housing 300 may include a through hole 320 penetrating the side surface of the housing 300, and a recess 330 formed in the side surface of the housing 300. The second portion of the extension portion 7330 may extend to the outside of the housing 300 through the through hole 320 of the housing 300, and may be disposed in the recess 330. The fixing portion 7340 may also be disposed in the recess 330.

[0373] When the OIS carrier 4000 moves, the extension portion 7330 of the first substrate 7300 may be bent.

[0374] Therefore, even when the OIS carrier 4000 moves during optical image stabilization, the first substrate 7300 can stably supply power to the iris coil 175 and the first coil 530 .

[0375] Fig.11 is an exploded perspective view showing a camera module according to another embodiment of the present disclosure.

[0376] Reference Fig.11 , with reference Figures 7 to 10B Compared to the camera module 4 shown in Fig.11 The camera module 5 shown in FIG. 5 may be different in terms of the lens module 200 and the focus adjustment unit 500. Fig.11 Portions related to the lens module 200 and the focus adjustment unit 500 are described.

[0377] The lens module 200 may be disposed in the aperture module 100. For example, the lens module 200 may be disposed in the base portion 110 (eg, see Figure 2) in the interior space.

[0378] That is, the aperture module 100 may be disposed in front of the lens module 200 .

[0379] In addition, the first magnet 510 may be disposed on the aperture module 100. For example, the first magnet 510 may be disposed on the base portion 110 of the aperture module 100.

[0380] The bottom surface of the first magnet 510 may be disposed lower than the bottom surface of the aperture magnet 174 in the optical axis (Z-axis) direction.

[0381] Fig.12 is an exploded perspective view showing an aperture module according to another embodiment of the present disclosure. Fig.13 It shows that Fig.12 The aperture drive unit of the aperture module is set Fig.12 An exploded perspective view of an example of a base portion and a rotating body of an aperture module.

Fig.15 It shows that Fig.12 A three-dimensional view of a state in which the traction yoke part and the auxiliary yoke of a camera module are separated from the base part.

[0383] Fig.16 is shown viewed from the side Fig.12 FIG. 1 is a diagram showing the arrangement of the magnet part, traction yoke part and auxiliary yoke of a camera module. Fig.17 It is shown Fig.12 A cross-sectional view of the aperture module. Fig.18 It is shown Fig.12 The aperture module is set Fig.12 A plan view of the rolling portion in the guide groove of the aperture module.

[0384] Reference Figures 12 to 18 An aperture module 100 ′ according to another embodiment is described.

[0385] refer to Figures 1 to 11 The aperture module 100 in the above-described embodiment can be used Figures 12 to 18 The aperture module 100 ′ shown in FIG.

[0386] The iris module 100 ′ may include a base portion 40 , a rotating body 30 , a plurality of blades 20 , and an iris driving unit 50 .

[0387] The aperture module 100' may further include a cover 10. The cover 10 may be coupled to the base 40. A plurality of blades 20 and a rotating body 30 may be disposed in a space between the cover 10 and the base 40.

[0388] The aperture module 100' can be connected to Figure 1 , Figure 4 , Figure 5 , Figure 7 and Fig.11 Any of the lens modules 200 shown in .

[0389] In an embodiment, the lens module 200 may include a first lens unit 210 and a second lens unit 230 spaced apart from each other in the optical axis (Z axis) direction. The aperture module 100' may be disposed between the first lens unit 210 and the second lens unit 230. For example, the first lens unit 210 may be coupled to the cover 10 of the aperture module 100', and the second lens unit 230 may be coupled to the base 40 of the aperture module 100'.

[0390] In an embodiment, the aperture module 100' may be disposed in front of the lens module 200. The lens module 200 may be disposed in the aperture module 100'. For example, the lens module 200 may be disposed in an inner space of the base portion 40 of the aperture module 100'.

[0391] The aperture module 100 ′ and the lens module 200 may move together in the optical axis (Z axis) direction for focus adjustment. For example, the aperture module 100 ′ and the lens module 200 may move together in the optical axis (Z axis) direction in response to a driving force generated by the focus adjustment unit 500 .

[0392] The aperture module 100' and the lens module 200 can move together in a direction perpendicular to the optical axis (Z axis) for optical image stabilization. For example, the aperture module 100' and the lens module 200 can move together in a first axis (X axis) direction and a second axis (Y axis) direction in response to a driving force generated by the optical image stabilization unit 600.

[0393] A portion of the focus adjustment unit 500 or a portion of the optical image stabilization unit 600 may be disposed on the aperture module 100 ′.

[0394] In an implementation, a portion of the optical image stabilization unit 600 may be disposed on the aperture module 100 ′.

[0395] Reference Fig.12 and Fig.13 , the arrangement of the optical image stabilization unit 600 may be similar to that of the reference Figures 1 to 6 Description of the embodiment.

[0396] For example, the second magnet 611 and the third magnet 631 of the optical image stabilization unit 600 may be disposed on the aperture module 100'. In other words, the second magnet 611 and the third magnet 631 may be disposed on the sidewall of the base portion 40 of the aperture module 100'. The second magnet 611 and the third magnet 631 may be disposed perpendicularly to each other.

[0397] In addition, the back yokes 44 and 45 may be disposed between the side wall of the base 40 and the second and third magnets 611 and 631. For example, the back yoke 44 may be disposed between one side wall of the base 40 and the second magnet 611, and the back yoke 45 may be disposed between the other side wall of the base 40 and the third magnet 631.

[0398] The back yokes 44 and 45 may be made of a magnetic material. Therefore, the magnetic field leakage of the second magnet 611 and the third magnet 631 may be prevented, and the magnetic field interference with the aperture driving unit 50 may be prevented.

[0399] In an embodiment, a portion of the focus adjustment unit 500 may be disposed on the aperture module 100'. Figures 12 to 18 , but the arrangement of the focus adjustment unit 500 may be similar to that of the reference Figures 7 to 11 Description of the embodiment.

[0400] For example, the first magnet 510 of the focus adjustment unit 500 may be disposed on the aperture module 100'. In other words, the first magnet 510 may be disposed on one side wall of the aperture module 100'. A back yoke (not shown) may be disposed between one side wall of the aperture module 100' and the first magnet 510.

[0401] The rotating body 30 may rotate relative to the base 40. For example, the rotating body 30 may be spaced apart from the base 40 in the optical axis (Z axis) direction and may rotate relative to the base 40. As the rotating body 30 rotates, the size of the incident hole 21 of the aperture module 100' may change.

[0402] A plurality of blades 20 may form an incident hole 21. The blades may be arranged so that a portion of the blade may overlap with another blade in the optical axis (Z axis) direction. For example, a group of a plurality of blades (e.g., three blades) and another group of a plurality of blades (e.g., three blades) may be stacked in sequence in the optical axis (Z axis) direction. A portion of each blade may overlap with the other two blades in the optical axis (Z axis) direction.

[0403] In an embodiment, six blades may be provided, three blades may form one group, and two groups of blades may be stacked in two layers, but the number of the plurality of blades 20 is not limited thereto.

[0404] The incident aperture 21 may be defined by the surface of each blade facing the optical axis (Z axis). The position of each blade may be changed by the aperture driving unit 50. Therefore, the size of the incident aperture 21 may be changed according to the position of each blade.

[0405] For example, the size of the entrance aperture 21 may be reduced or increased by rotating each blade.

[0406] A plurality of blades 20 may be coupled to the base 40 and the rotating body 30. Since each blade may have the same shape, one blade may be described below.

[0407] The blade may include a through hole 22. For example, the blade may have the through hole 22 at the outer end of the blade, and the through hole 22 may have a shape penetrating the blade in the optical axis (Z-axis) direction.

[0408] The through hole 22 of the blade may be coupled to the base 40. For example, a protrusion 41 protruding in the optical axis (Z axis) direction may be provided on the base 40, and the protrusion 41 may be coupled to the through hole 22 of the blade. A plurality of protrusions 41 equal in number to the plurality of blades 20 may be provided.

[0409] The protrusion 41 may form a rotation axis of the blade. The protrusion 41 and the through hole 22 may have corresponding sizes.

[0410] Furthermore, the blade may include a guide hole 23. For example, the blade may have the guide hole 23 spaced apart from the through hole 22.

[0411] The guide hole 23 of the blade may be coupled to the rotating body 30. For example, a guide protrusion 31 protruding in the optical axis (Z axis) direction may be provided on the rotating body 30, and the guide protrusion 31 may be coupled to the guide hole 23 of the blade. A plurality of guide protrusions 31 equal in number to the plurality of blades 20 may be provided.

[0412] The size of the guide hole 23 may be greater than that of the guide protrusion 31. For example, the width of the guide hole 23 may correspond to the diameter of the guide protrusion 31, and the length of the guide hole 23 may be greater than the diameter of the guide protrusion 31.

[0413] The shape of the guide hole 23 is not limited to Fig.12 For example, the shape of the guide hole 23 may be changed as long as the position of the blade can be moved as the rotating body 30 moves.

[0414] Therefore, as the rotating body 30 rotates, the guide protrusion 31 may move in the guide hole 23 , and thus, the blade may rotate using the protrusion 41 of the base 40 as a rotation axis.

[0415] The first spacer 11 may be disposed between the plurality of blades 20 and the cover 10. For example, the first spacer 11 may be coupled to the rotating body 30 and disposed between the plurality of blades 20 and the cover 10. The first spacer 11 may cover at least a portion of an upper surface of the plurality of blades 20. A surface of the first spacer 11 may be coated in black.

[0416] The first spacer 11 may have a through hole through which light passes, and a size of the through hole of the first spacer 11 may be greater than a maximum size of the incident hole 21 formed by the plurality of blades 20 .

[0417] The second spacer 12 may be disposed between the rotating body 30 and the plurality of blades 20. For example, the second spacer 12 may be coupled to the rotating body 30 and disposed between the rotating body 30 and the plurality of blades 20. The second spacer 12 may cover at least a portion of a lower surface of the plurality of blades 20. A surface of the second spacer 12 may be coated in black.

[0418] The second spacer 12 may have a through hole through which light passes, and the size of the through hole of the second spacer 12 may be larger than the maximum size of the incident hole 21 formed by the plurality of blades 20. In addition, the size of the through hole of the second spacer 12 may be smaller than that of the through hole of the first spacer 11.

[0419] The aperture driving unit 50 may move the rotating body 30 to change the size of the incident hole 21. For example, the aperture driving unit 50 may generate a driving force to rotate the rotating body 30.

[0420] As the rotating body 30 rotates, the guide protrusion 31 of the rotating body 30 may move in the guide holes 23 of the plurality of blades 20 , and thus the plurality of blades 20 may rotate using the protrusion 41 of the base 40 as a rotation axis, and the size of the incident hole 21 may change.

[0421] The aperture driving unit 50 may include a magnet portion 51 and a coil portion 52. The magnet portion 51 and the coil portion 52 may be disposed to face each other in the optical axis (Z-axis) direction.

[0422] The magnet part 51 may be disposed on one of the rotating body 30 and the base 40 , and the coil part 52 may be disposed on the other of the rotating body 30 and the base 40 .

[0423] For example, the magnet part 51 may be installed on the rotating body 30. As an example, the magnet part 51 may be installed on the lower surface of the rotating body 30.

[0424] The magnet portion 51 may include a plurality of aperture magnets spaced apart from each other. As an example, the magnet portion 51 may include a first aperture magnet 51a and a second aperture magnet 51b disposed on opposite sides in a direction perpendicular to the optical axis (Z axis).

[0425] The first aperture magnet 51a and the second aperture magnet 51b may be magnetized so that one surface (e.g., the surface facing the coil portion 52) may have both an N pole and an S pole. For example, one surface of the first aperture magnet 51a and the second aperture magnet 51b facing the coil portion 52 may include an N pole, a neutral region, and an S pole sequentially arranged in a direction perpendicular to the optical axis (Z axis) (e.g., the rotation direction of the rotating body 30).

[0426] The coil portion 52 may be disposed so as to face the magnet portion 51. For example, the coil portion 52 may be disposed so as to face the magnet portion 51 in the optical axis (Z-axis) direction.

[0427] The coil portion 52 may be disposed on the aperture substrate 54, and the aperture substrate 54 may be mounted on the base 40 so that the magnet portion 51 and the coil portion 52 may face each other in the optical axis (Z axis) direction. As an example, the coil portion 52 may be disposed on one surface of the aperture substrate 54. The aperture substrate 54 may be mounted on the upper surface of the base 40.

[0428] In addition, the aperture substrate 54 may include a first extension portion 54a extending from the upper surface of the base portion 40 to the side surface of the base portion 40. The first extension portion 54a may be electrically connected to the printed circuit board 830. A connection substrate may be provided between the first extension portion 54a and the printed circuit board 830, at least a portion of which is flexible.

[0429] The coil portion 52 may include a plurality of aperture coils. As an example, the coil portion 52 may include a first aperture coil 52a and a second aperture coil 52b disposed on opposite sides in a direction perpendicular to the optical axis (Z axis).

[0430] When the size of the incident hole 21 is changed, the magnet part 51 may be a moving member mounted on and rotated together with the rotating body 30 , and the coil part 52 may be a fixed member fixed to the base 40 .

[0431] In another embodiment, the magnet part 51 and the coil part 52 may be disposed opposite to each other. In this case, since the coil part 52 and the aperture substrate 54 are mounted on the rotating body 30 and rotate together with the rotating body 30, at least a portion of the aperture substrate 54 may be configured to be flexible.

[0432] When power is applied to the coil part 52 , the rotating body 30 may rotate in response to an electromagnetic force generated between the magnet part 51 and the coil part 52 .

[0433] In an embodiment, a portion of the aperture driving unit 50 (eg, the magnet portion 51 ) may rotate to rotate the rotating body 30 .

For example, each of the 1-1 guide groove 42a to the 1-4 guide groove 42d may have a “┗”-shaped cross section.

[0450] The second guide groove portion 32 may include a 2-1 guide groove 32a, a 2-2 guide groove 32b, a 2-3 guide groove 32c, and a 2-4 guide groove 32d. The 2-1 guide groove 32a to 2-4 guide groove 32d may be spaced apart from each other in the circumferential direction of the rotating body 30.

[0451] The 2-1 guide groove 32a to the 2-4 guide groove 32d may include a bottom surface formed in one surface (e.g., the lower surface) of the rotating body 30, and a side surface extending from the bottom surface toward the base 40 in the optical axis (Z axis) direction. For example, each of the 2-1 guide groove 32a to the 2-4 guide groove 32d may have a “┓”-shaped cross section.

[0452] The 1-1 guide groove 42a and the 2-1 guide groove 32a may be disposed to face each other, and one of the two rolling balls of the first rolling member RB1 (eg, the first rolling ball RB1a) may be disposed in a space between the 1-1 guide groove 42a and the 2-1 guide groove 32a.

[0454] Furthermore, the 1-2 guide groove 42b and the 2-2 guide groove 32b may be arranged to face each other, and the other of the two rolling balls of the first rolling member RB1 (eg, the second rolling ball RB1b) may be arranged in the space between the 1-2 guide groove 42b and the 2-2 guide groove 32b.

[0455] The bottom surface of the 1-2 guide groove 42b and the bottom surface of the 2-2 guide groove 32b may face each other in the optical axis (Z axis) direction, and the side surface of the 1-2 guide groove 42b and the side surface of the 2-2 guide groove 32b may face each other in a direction perpendicular to the optical axis (Z axis).

[0456] The first rolling ball RB1a of the first rolling member RB1 may make two-point contact with each of the 1-1 guide groove 42a and the 2-1 guide groove 32a.

[0457] For example, the first rolling ball RB1a may contact the 1-1 guide groove 42a at two points, and may contact the 2-1 guide groove 32a at two points. For example, the first rolling ball RB1a may contact the bottom surface and the side surface of the 1-1 guide groove 42a, and may contact the bottom surface and the side surface of the 2-1 guide groove 32a.

[0458] The contact points of the bottom surface of the 1-1 guide groove 42a and the contact points of the bottom surface of the 2-1 guide groove 32a can face each other in the direction of the optical axis (Z axis), and the contact points of the side surfaces of the 1-1 guide groove 42a and the contact points of the side surfaces of the 2-1 guide groove 32a can face each other in a direction perpendicular to the optical axis (Z axis).

[0459] For example, when viewed in the circumferential direction of the base 40 and the rotating body 30, a virtual line connecting the contact point of the bottom surface of the 1-1 guide groove 42a to the contact point of the bottom surface of the 2-1 guide groove 32a, and a virtual line connecting the contact point of the side surface of the 1-1 guide groove 42a to the contact point of the side surface of the 2-1 guide groove 32a may have a “+” shape.

[0460] The second rolling ball RB1b of the first rolling member RB1 may be in two-point contact with the 1-2 guide groove 42b and the 2-2 guide groove 32b.

[0461] For example, the second rolling ball RB1b may contact the 1-2 guide groove 42b at two points, and may contact the 2-2 guide groove 32b at two points. As an example, the second rolling ball RB1b may contact the bottom surface and the side surface of the 1-2 guide groove 42b, and may contact the bottom surface and the side surface of the 2-2 guide groove 32b.

[0462] The contact points of the bottom surface of the 1-2 guide groove 42b and the contact points of the bottom surface of the 2-2 guide groove 32b can face each other in the direction of the optical axis (Z axis), and the contact points of the side surfaces of the 1-2 guide groove 42b and the contact points of the side surfaces of the 2-2 guide groove 32b can face each other in a direction perpendicular to the optical axis (Z axis).

[0463] For example, when viewed in the circumferential direction of the base 40 and the rotating body 30, a virtual line connecting the contact point of the bottom surface of the 1-2 guide groove 42b to the contact point of the bottom surface of the 2-2 guide groove 32b, and a virtual line connecting the contact point of the side surface of the 1-2 guide groove 42b to the contact point of the side surface of the 2-2 guide groove 32b may have a “+” shape.

[0464] The first rolling member RB1 , the 1 - 1 guide groove 42 a , the 1 - 2 guide groove 42 b , the 2 - 1 guide groove 32 a , and the 2 - 2 guide groove 32 b may serve as a main guide that guides the rotation of the rotating body 30 .

[0465] The 1-3 guide groove 42c and the 2-3 guide groove 32c may be disposed to face each other, and the second rolling member RB2 may be disposed in a space between the 1-3 guide groove 42c and the 2-3 guide groove 32c.

[0466] The bottom surface of the 1-3 guide groove 42c and the bottom surface of the 2-3 guide groove 32c may face each other in the optical axis (Z axis) direction, and the side surface of the 1-3 guide groove 42c and the side surface of the 2-3 guide groove 32c may face each other in a direction perpendicular to the optical axis (Z axis).

[0467] The second rolling member RB2 may be in contact with the 1-3 guide groove 42c and the 2-3 guide groove 32c. The number of contact points between the second rolling member RB2 and the 1-3 guide groove 42c and the 2-3 guide groove 32c may be two or three.

[0468] For example, when the number of contact points between the second rolling member RB2 and the 1-3 guide groove 42c and the 2-3 guide groove 32c is two, the second rolling member RB2 may contact the bottom surface of the 1-3 guide groove 42c and the bottom surface of the 2-3 guide groove 32c.

[0469] When the number of contact points between the second rolling member RB2 and the 1-3 guide groove 42c and the 2-3 guide groove 32c is three, the second rolling member RB2 can contact the bottom surface of the 1-3 guide groove 42c and the bottom surface of the 2-3 guide groove 32c, and can contact the side surface of the 1-3 guide groove 42c or the side surface of the 2-3 guide groove 32c.

[0470] A distance between a side surface of the 1-3 guide groove 42c and a side surface of the 2-3 guide groove 32c facing each other in a direction perpendicular to the optical axis (Z-axis) direction may be greater than a diameter of the second rolling member RB2.

[0471] The second rolling member RB2 , the 1 - 3 guide groove 42 c , and the 2 - 3 guide groove 32 c may serve as auxiliary guides to support the rotation of the rotating body 30 .

[0472] When viewed in the optical axis (Z-axis) direction, the rotating body 30 may be supported on the base portion 40 at three points (eg, a triangular supporting area) by the first rolling member RB1 and the second rolling member RB2 .

[0473] The 1-4 guide groove 42d and the 2-4 guide groove 32d may be provided to face each other, and the third rolling member RB3 may be provided in a space between the 1-4 guide groove 42d and the 2-4 guide groove 32d.

[0474] The bottom surface of the 1-4 guide groove 42d and the bottom surface of the 2-4 guide groove 32d may face each other in the optical axis (Z axis) direction, and the side surface of the 1-4 guide groove 42d and the side surface of the 2-4 guide groove 32d may face each other in a direction perpendicular to the optical axis (Z axis).

[0475] The third rolling member RB3 may contact one or both of the 1-4 guide groove 42d and the 2-4 guide groove 32d. The number of contact points between the third rolling member RB3 and the 1-4 guide groove 42d and the 2-4 guide groove 32d may be one or two.

[0476] For example, when the number of contact points between the third rolling member RB3 and the 1-4 guide groove 42d and the 2-4 guide groove 32d is one, the third rolling member RB3 may contact the bottom surface of the 1-4 guide groove 42d or the bottom surface of the 2-4 guide groove 32d.

[0477] When the number of contact points between the third rolling member RB3 and the 1-4 guide groove 42d and the 2-4 guide groove 32d is two, the third rolling member RB3 can be in single-point contact with the bottom surface of the 1-4 guide groove 42d or the bottom surface of the 2-4 guide groove 32d, and can be in single-point contact with the side surface of the 1-4 guide groove 42d or the side surface of the 2-4 guide groove 32d.

[0478] In an embodiment, the distance between the bottom surface of the 1-4 guide groove 42d and the bottom surface of the 2-4 guide groove 32d in the optical axis (Z axis) direction may be greater than the distance between the bottom surface of the 1-1 guide groove 42a and the bottom surface of the 2-1 guide groove 32a in the optical axis (Z axis) direction.

[0479] In an embodiment, a distance between a bottom surface of the 1-4 guide groove 42d and a bottom surface of the 2-4 guide groove 32d in the optical axis (Z-axis) direction may be greater than a diameter of the fourth rolling ball of the third rolling member RB3.

[0480] In an embodiment, a diameter of the fourth rolling ball of the third rolling member RB3 may be smaller than diameters of the first and second rolling balls RB1a and RB1b of the first rolling member RB1 and a diameter of the third rolling ball of the second rolling member RB2.

[0481] The third rolling member RB3 can prevent the rotating body 30 from tilting relative to the base 40 during an external impact. That is, by preventing the rotating body 30 from tilting relative to the base 40 during an external impact, the rolling portion RB can be prevented from being separated from the base 40 and the rotating body 30.

[0482] However, the third rolling member RB3 may be an optional component, and when the third rolling member RB3 is not provided, the inclination of the rotating body 30 may be prevented by adjusting the positions of the first and second rolling members RB1 and RB2.

[0483] When viewed in the optical axis (Z-axis) direction, the rotating body 30 may be supported on the base portion 40 at three points by the first rolling member RB1 and the second rolling member RB2 .

[0484] In this case, the center point CP of the attraction acting between the magnet part 51 and the traction yoke part 55 may need to be set in a supporting area that connects the contact point of the first rolling member RB1 and the base part 40 (or the rotating body 30) and the contact point of the second rolling member RB2 and the base part 40 (or the rotating body 30).

[0485] Since the width of the bearing area may increase toward the first rolling member RB1 , the center point CP of the attractive force may need to be disposed closer to the first rolling member RB1 .

[0486] For this reason, by differently configuring the sizes of the first and second traction yokes 55 a and 55 b , the center point CP of the attraction force may be disposed closer to the first rolling member RB1 .

[0487] In an embodiment, an area of ​​the first pulling yoke 55 a facing the first aperture magnet 51 a may be greater than an area of ​​the second pulling yoke 55 b facing the second aperture magnet 51 b .

[0488] In other words, by configuring the size of the first traction yoke 55 a to be larger than the size of the second traction yoke 55 b , the center point CP of the attraction force can be disposed closer to the first rolling member RB1 .

[0489] As another example, by configuring the size of the first aperture magnet 51 a to be larger than the size of the second aperture magnet 51 b , the center point CP of the attractive force can be disposed closer to the first rolling member RB1 .

[0490] As another example, by configuring the distance between the first aperture magnet 51a and the first traction yoke 55a in the optical axis (Z-axis) direction to be smaller than the distance between the second aperture magnet 51b and the second traction yoke 55b in the optical axis (Z-axis) direction, the center point CP of the attraction can be set to be closer to the first rolling member RB1.

[0491] The first pulling yoke 55a may be configured so that the area of ​​one portion thereof may be larger than the area of ​​the remaining portion thereof. For example, the first pulling yoke 55a may have a rectangular shape, and may have a protrusion protruding from a portion of the long side of the rectangle. Therefore, when no power is applied to the aperture drive unit 50, the relative position of the first aperture magnet 51a with respect to the first pulling yoke 55a may be kept constant.

[0492] In an embodiment, the first traction yoke 55a may have an asymmetric shape with respect to the center of the first traction yoke 55a. For example, with respect to a virtual line passing through the optical axis (Z axis) and intersecting the center of the first traction yoke 55a, the area of ​​the first traction yoke 55a on one side of the virtual line may be greater than the area of ​​the first traction yoke 55a on the other side of the virtual line.

[0493] As another example, the width of the first pulling yoke 55 a may be configured to increase from one end in the length direction to the other end in the length direction.

[0494] As another example, the first pulling yoke 55a may be provided as two yokes disposed adjacent to each other. In this case, the size of one of the two yokes may be larger than the size of the other of the two yokes.

[0495] The aperture module 100 ′ may further include an auxiliary yoke 56 .

[0496] The auxiliary yoke 56 may be disposed closer to the first aperture magnet 51 a than to the second aperture magnet 51 b .

[0497] When viewed in the optical axis (Z-axis) direction, the first aperture magnet 51 a , the first pulling yoke 55 a , and the auxiliary yoke 56 may be disposed in a space between the first rolling ball RB1 a and the second rolling ball RB1 b .

[0498] The auxiliary yoke 56 may be disposed on a side wall extending from the surface of the base 40 in the optical axis (Z axis) direction. For example, the auxiliary yoke 56 may be disposed so that at least a portion thereof may face the first aperture magnet 51a in a direction perpendicular to the optical axis (Z axis). The auxiliary yoke 56 may be made of a magnetic material. In an embodiment, the auxiliary yoke 56 may be disposed on an inner surface of a side wall of the base 40.

[0499] The auxiliary yoke 56 may be integrally coupled with the base part 40 by insert injection molding. In this case, the auxiliary yoke 56 may be integrated with the base part 40 during manufacturing by injecting a resin material into a mold into which the auxiliary yoke 56 has been inserted.

[0500] In an embodiment, the position of the top of the auxiliary yoke 56 may be disposed between the upper surface and the lower surface of the first aperture magnet 51 a in the optical axis (Z-axis) direction.

[0501] Reference Fig.16 , an attractive force can be applied in the direction of the optical axis (Z axis) by the first aperture magnet 51a and the first traction yoke 55a, and an attractive force can be applied in a direction intersecting the optical axis (Z axis) (for example, a direction perpendicular to the optical axis (Z axis) or a direction inclined downward while intersecting the optical axis (Z axis)) by the first aperture magnet 51a and the auxiliary yoke 56.

[0502] In other words, attractive forces may act on the first aperture magnet 51 a in at least two directions that intersect with each other.

[0503] Due to the attractive force acting between the first aperture magnet 51 a and the first pulling yoke 55 a , the rotating body 30 including the first aperture magnet 51 a may be pulled toward the base portion 40 including the first pulling yoke 55 a in the direction of the optical axis (Z axis).

[0504] Therefore, due to the attractive force acting between the first aperture magnet 51a and the first pulling yoke 55a, the first rolling ball RB1a can be kept in contact with the bottom surface of the 1-1 guide groove 42a and the bottom surface of the 2-1 guide groove 32a.

[0505] Due to the attractive force acting between the first aperture magnet 51a and the first pulling yoke 55a, the second rolling ball RB1b can be kept in contact with the bottom surface of the 1-2 guide groove 42b and the bottom surface of the 2-2 guide groove 32b.

[0506] Due to the attractive force acting between the first aperture magnet 51 a and the auxiliary yoke 56 , the rotating body 30 including the first aperture magnet 51 a may be pulled toward the base portion 40 including the auxiliary yoke 56 in a direction intersecting the optical axis (Z axis).

[0507] Therefore, due to the attractive force acting between the first aperture magnet 51 a and the auxiliary yoke 56 , the first rolling ball RB1 a can be kept in contact with the side surface of the 1-1 guide groove 42 a and the side surface of the 2-1 guide groove 32 a .

[0508] Furthermore, due to the attractive force acting between the first aperture magnet 51 a and the auxiliary yoke 56 , the second rolling ball RB1 b can be kept in contact with the side surface of the 1 - 2 guide groove 42 b and the side surface of the 2 - 2 guide groove 32 b .

[0509] Each of the side surface of the 1-1 guide groove 42a, the side surface of the 1-2 guide groove 42b, the side surface of the 2-1 guide groove 32a, and the side surface of the 2-2 guide groove 32b may be a curved surface.

[0510] For example, the curvature radius of the side surface of the 1-1 guide groove 42a and the curvature radius of the side surface of the 1-2 guide groove 42b may be the same. In addition, the curvature radius of the side surface of the 2-1 guide groove 32a and the curvature radius of the side surface of the 2-2 guide groove 32b may be the same.

[0511] Furthermore, a virtual circle passing through the side surface of the 1-1 guide groove 42a and the side surface of the 1-2 guide groove 42b and a virtual circle passing through the side surface of the 2-1 guide groove 32a and the side surface of the 2-2 guide groove 32b may be concentric.

[0512] The auxiliary yoke 56 may be disposed further outward in a direction perpendicular to the optical axis (Z axis) than a virtual circle passing through the side surface of the 1-1 guide groove 42a and the side surface of the 1-2 guide groove 42b. In addition, the auxiliary yoke 56 may be disposed further outward in a direction perpendicular to the optical axis (Z axis) than a virtual circle passing through the side surface of the 2-1 guide groove 32a and the side surface of the 2-2 guide groove 32b.

[0513] When the aperture driving unit 50 generates driving force, the first rolling ball RB1a can roll along the side surface of the 1-1 guide groove 42a and the side surface of the 2-1 guide groove 32a, and the second rolling ball RB1b can roll along the side surface of the 1-2 guide groove 42b and the side surface of the 2-2 guide groove 32b.

[0514] Therefore, the rotating body 30 may rotate by being guided by the first rolling ball RB1a and the second rolling ball RB1b.

[0515] Reference Fig.16 , an attractive force can be applied in the direction of the optical axis (Z axis) by the second aperture magnet 51b and the second pulling yoke 55b.

[0516] Due to the attractive force acting between the second aperture magnet 51 b and the second pulling yoke 55 b , the rotating body 30 including the second aperture magnet 51 b may be pulled toward the base portion 40 including the second pulling yoke 55 b in the direction of the optical axis (Z axis).

[0517] When the rotating body 30 rotates, due to the attraction acting between the second aperture magnet 51b and the second traction yoke 55b, the second rolling member RB2 can maintain contact with the bottom surface of the 1-3 guide groove 42c and the bottom surface of the 2-3 guide groove 32c, and the rotating body 30 can maintain three-point support for the rolling part RB.

[0518] In an implementation, the aperture module 100 ′ may sense the position of the rotating body 30 .

[0519] For this purpose, an aperture position sensor 53 may be provided. The aperture position sensor 53 may be disposed on an aperture substrate 54 facing the magnet portion 51. For example, the aperture position sensor 53 may face one or both of the first aperture magnet 51a and the second aperture magnet 51b in the optical axis (Z axis) direction.

[0520] The aperture position sensor 53 may be a Hall sensor.

[0521] According to the aforementioned embodiments, the camera module can control the amount of incident light and can reduce power consumption when the lens module is moved.
