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

[0067] The following specific embodiments are provided to help the reader obtain a comprehensive understanding of the methods, devices and / or systems described herein. However, various changes, modifications and equivalents of the methods, devices and / or systems described herein will be apparent after understanding the disclosure of the present application. For example, the order of operations described herein is merely an example, and except for operations that must occur in a specific order, it is not limited to the order set forth herein, but can be changed, which will be apparent after understanding the disclosure of the present application. In addition, for greater clarity and brevity, the description of features known in the art may be omitted.

[0068] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein are provided merely 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.

[0069] 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, the element may be directly “on,” “connected to,” or “coupled to” the other element, or one or more other elements may be present between the element and the other element. Conversely, when an element is described as being “directly on,” “directly connected to,” or “directly coupled to” another element, no other elements may be present between the element and the other element.

[0070] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0071] 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. Rather, these terms are only used to distinguish one member, component, region, layer or portion from another member, component, region, layer or portion. Therefore, without departing from the teachings of the examples described herein, the first member, first component, first region, first layer or first portion mentioned in these examples may also be referred to as the second member, second component, second region, second layer or second portion.

[0072] Spatially relative terms such as "above", "above", "below", and "below" may be used herein for descriptive convenience to describe the relationship of one element relative to another element as shown in the accompanying drawings. In addition to covering the orientations depicted in the accompanying drawings, these spatially relative terms are intended to also cover different orientations of the device in use or operation. For example, if the device in the accompanying drawings is flipped, an element described as being "above" or "above" another element relative to the other element will be "below" or "below" the other element relative to the other element. Therefore, depending on the spatial orientation of the device, the term "above" covers both orientations of "above" and "below". 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 should be interpreted accordingly.

[0073] The terms used herein are only used to describe various examples and are not used to limit the present disclosure. Unless the context clearly indicates otherwise, the terms "a", "an" and "the" are intended to include plural forms as well. The terms "include", "comprise" and "have" indicate the presence of the features, numbers, operations, components, elements and / or combinations thereof, but do not exclude the presence or addition of one or more other features, numbers, operations, components, elements and / or combinations thereof.

[0074] In the present specification, the optical axis (Z axis) direction may be a direction extending up and down along the optical axis (Z axis) of the lens barrel 210 or a direction parallel to the optical axis (Z axis).

[0075] The first axis (X axis) direction and the second axis (Y axis) direction may be directions perpendicular to each other while intersecting the optical axis (Z axis) direction. For example, the first axis (X axis) direction may be a direction perpendicular to the optical axis (Z axis) direction, and the second axis (Y axis) direction may be a direction perpendicular to both the optical axis (Z axis) direction and the first axis (X axis) direction.

[0076] The present disclosure relates 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.

[0077] Figure 1 is a perspective view of a camera module according to an embodiment of the present disclosure, Figure 2 yes Figure 1 An exploded perspective view of the camera module, and Figure 3 yes Figure 1 and Figure 2 A perspective view of a variation of a housing of a camera module.

[0078] Reference Figure 1 and Figure 2 , a camera module 1 according to an embodiment of the present disclosure includes a lens module 200 , a reflective member 300 , and a housing 100 .

[0079] The lens module 200 may include a lens barrel 210 and a bracket 230. The lens barrel 210 may have a hollow cylindrical shape, and at least one lens for imaging an object may be accommodated inside the lens barrel 210. In the case where a plurality of lenses are arranged, the plurality of lenses may be installed inside the lens barrel 210 along the optical axis (Z axis).

[0080] The lens barrel 210 may move in one or more of three axial directions intersecting each other.

[0081] The lens barrel 210 may be coupled to the bracket 230. The lens barrel 210 and the bracket 230 may move together.

[0082] The housing 100 may have an internal space. In an embodiment, the housing 100 may be shaped like a quadrilateral (e.g., rectangular) box. One or more openings 130 may be formed in one surface of the housing 100. The internal space of the housing 100 may be exposed to the outside of the housing 100 through the openings 130. One surface of the housing 100 may be as shown in FIG. Figure 2 The upper surface of the housing 100 is shown in FIG.

[0083] In an embodiment, the one or more openings 130 formed in one surface of the housing 100 may include a first opening 131 and a second opening 132. The first opening 131 and the second opening 132 may be arranged to be spaced apart from each other in a direction intersecting the optical axis (Z axis). The partition wall 133 may be formed as shown in FIG. Figure 2 As shown in FIG. 1 , the PCB is disposed between the first opening 131 and the second opening 132 .

[0084] The lens barrel 210 may be disposed in the first opening 131 , and the image sensor module 800 may be disposed in the second opening 132 .

[0085] Reference Figure 3 In another embodiment, an opening 130 may be formed in a surface of the housing 100'. Figure 2 Unlike the case 100 shown in FIG. 1 , the case 100 ′ may have one opening 130 formed on one surface of the case 100 ′ by not forming a partition wall 133 in the case 100 ′.

[0086] The reflective member 300 may be disposed in the internal space of the housing 100. In addition, the lens barrel 210 of the lens module 200 may be disposed in front of the reflective member 300. Here, the expression "in front of" may refer to a positive optical axis (Z axis) direction (+Z axis direction) relative to the reflective member 300. For example, the lens barrel 210 may be spaced apart upward from the reflective member 300 in the optical axis (Z axis) direction.

[0087] Therefore, light may be incident on the reflective member 300 after passing through the lens barrel 210 .

[0088] The lens module 200 may be moved in one or more of three axial directions intersecting each other. In addition, the lens module 200 may be moved relative to the reflective member 300.

[0089] For example, the lens module 200 may be moved in the direction of the optical axis (Z axis) for focus adjustment. In addition, the lens module 200 may be moved in a direction perpendicular to the optical axis (Z axis) for optical image stabilization.

[0090] In an embodiment, the three axial directions intersecting each other may be an optical axis (Z-axis) direction, a first axis (X-axis) direction, and a second axis (Y-axis) direction.

[0091] The camera module 1 may further include a carrier 400 and a guide frame 500 .

[0092] The bearing portion 400 may be disposed inside the housing 100 and may be movable in the optical axis (Z axis) direction relative to the housing 100. Since the reflective member 300 is fixed to the housing 100, the bearing portion 400 may also be movable relative to the reflective member 300.

[0093] The lens module 200 may be disposed on the carrier 400, and the carrier 400 and the lens module 200 may move together in the optical axis (Z axis) direction. Therefore, the camera module 1 may adjust the focus.

[0094] In addition, the lens module 200 may be moved in a direction perpendicular to the optical axis (Z-axis) direction to stabilize the optical image.

[0095] The guide frame 500 may be disposed between the carrier 400 and the lens module 200. The guide frame 500 may be used to guide the lens module 200 to move in a direction perpendicular to the optical axis (Z-axis) direction.

[0096] The guide frame 500 may be a quadrilateral (eg, rectangular) frame having an opening in the optical axis (Z axis) direction and one side open. In an embodiment, the planar shape of the guide frame 500 may be approximately At least a portion of the reflective member 300 may be located on one side of the opening of the guide frame 500. Thus, the guide frame 500 and the reflective member 300 may be prevented from interfering with each other.

[0097] In another embodiment, the guide frame 500 may be a quadrilateral (eg, rectangular) frame with two sides open. In this case, the planar shape of the guide frame 500 may be approximately shape.

[0098] At least a portion of the lens module 200 may be accommodated in the housing 100. In an embodiment, the carrier 400 may be disposed inside the housing 100, and the lens module 200 may be accommodated inside the carrier 400. At least a portion of the lens barrel 210 may protrude outside the housing 100.

[0099] In addition, the lens module 200 may be disposed in the first opening 131 formed in one surface of the housing 100 .

[0100] The camera module 1 may adjust the focus by moving the lens module 200 in the optical axis (Z axis) direction, and may stabilize the optical image by moving the lens module 200 in a direction perpendicular to the optical axis (Z axis) when capturing an image.

[0101] The camera module 1 may further include a focus adjustment unit 600 that moves the lens module 200 in the optical axis (Z axis) direction and an optical image stabilization unit 700 that moves the lens module 200 in a direction perpendicular to the optical axis (Z axis) direction.

[0102] The camera module 1 may further include an image sensor module 800 and a housing 110 .

[0103] Fig.10 is an image sensor module with Figure 1 A perspective view of a state in which the camera module is separated and shown in a bottom perspective view, and Fig.11 yes Fig.10 An exploded perspective view of an image sensor module.

[0104] Reference Fig.10 and Fig.11 , the image sensor module 800 may include an image sensor 810 and a printed circuit board 830 connected to the image sensor 810 , and may further include a sensor housing 850 .

[0105] The image sensor 810 may convert light incident 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.

[0106] The electrical signal converted by the image sensor 810 may be output as an image through a display unit of a portable electronic device on which the camera module 1 is mounted.

[0107] 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.

[0108] The image sensor 810 may have an imaging surface on which light is received, and the imaging surface of the image sensor 810 may be a surface intersecting with the optical axis (Z axis) direction. The image sensor 810 may be disposed to be spaced apart from the reflective member 300. For example, the image sensor 810 may be spaced apart upward from the reflective member 300 in the optical axis (Z axis) direction.

[0109] In an embodiment, both the lens barrel 210 and the image sensor 810 may be disposed higher than the reflective member 300 in the optical axis (Z-axis) direction. For example, the lens barrel 210 and the image sensor 810 may be disposed closer to the object than the reflective member 300. That is, among the lens barrel 210, the image sensor 810, and the reflective member 300, the lens barrel 210 and the image sensor 810 may be those closest to the object, and the reflective member 300 may be the one farthest from the object.

[0110] The image sensor module 800 may be mounted in the housing 100. As an example, the image sensor module 800 may be disposed in the second opening 132 formed in one surface of the housing 100.

[0111] In an embodiment, the sensor housing 850 may be coupled to the printed circuit board 830, and the image sensor 810 may be disposed in an inner space of the sensor housing 850. In addition, either or both of the sensor housing 850 and the printed circuit board 830 may be coupled to the housing 100.

[0112] The lens barrel 210 of the lens module 200 and the image sensor 810 of the image sensor module 800 can be respectively arranged in the first opening 131 and the second opening 132 of the housing 100, and can be arranged to be spaced apart from each other in a direction intersecting the optical axis (Z axis) direction (for example, the first axis (X axis) direction).

[0113] The housing 110 may be coupled to the case 100 to cover an outer surface of the case 100 , and may play a role in protecting components inside the camera module 1 .

[0114] The reflective member 300 may have one surface facing the optical axis (Z axis) direction. One surface of the reflective member 300 may be a surface intersecting the optical axis (Z axis) direction. As an example, one surface of the reflective member 300 may be as follows: Figure 2The upper surface of the reflective member 300 is shown in FIG.

[0115] The lens barrel 210 and the image sensor 810 may be disposed closer to the object than the reflective member 300, and may be spaced apart from each other in a direction intersecting the optical axis (Z-axis) direction. That is, among the lens barrel 210, the image sensor 810, and the reflective member 300, the lens barrel 210 and the image sensor 810 may be those closest to the object, and the reflective member 300 may be the one farthest from the object.

[0116] Fig. 9 yes Figure 1 and Figure 2 Schematic cross-sectional view of a camera module.

[0117] Reference Fig. 9 In an embodiment, the lens barrel 210 may face a portion of one surface (eg, an upper surface) of the reflective member 300 , and the image sensor 810 may face another portion of one surface (eg, an upper surface) of the reflective member 300 .

[0118] The reflective member 300 may have one or more reflective surfaces. Since the light having passed through the lens module 200 enters the image sensor 810 after being reflected by the reflective member 300, a long optical path may be formed within a limited space.

[0119] Furthermore, since the lens barrel 210 is disposed in front of the reflective member 300 , the Fno (F number) of the camera module 1 may be reduced to capture a bright image.

[0120] Fig.12 yes Figure 2 A cross-sectional view of a reflective component.

[0121] Reference Fig.12 In an embodiment, the reflective member 300 may be in the form of a trapezoidal prism. The reflective member 300 may include an incident surface 310 into which light is incident, a first reflective surface 320 that reflects light that has passed through the incident surface 310, a second reflective surface 330 that reflects light reflected from the first reflective surface 320, a third reflective surface 340 that reflects light reflected from the second reflective surface 330, and an exit surface 350 that emits light reflected from the third reflective surface 340. The light that has passed through the exit surface 350 may be incident on the image sensor 810.

[0122] That the image sensor 810 is disposed closer to the object than the reflective member 300 may mean that the image sensor 810 is disposed closer to the object than the exit surface 350 of the reflective member 300 .

[0123] In an embodiment, the incident surface 310 , the second reflective surface 330 , and the exit surface 350 may be one surface extending on the same plane. For example, the incident surface 310 , the second reflective surface 330 , and the exit surface 350 may be parts of one surface of the reflective member 300 .

[0124] Each of the first reflective surface 320 and the third reflective surface 340 may be inclined with respect to the second reflective surface 330 .

[0125] A portion of the reflective member 300 may be disposed in the inner space of the carrier 400. In an implementation, the incident surface 310 and the first reflective surface 320 of the reflective member 300 may be disposed in the inner space of the carrier 400.

The area of ​​the bottom surface 360 ​​may be smaller than the area of ​​the upper surface of the reflective member 300 (e.g., the area of ​​the incident surface 310+the area of ​​the second reflective surface 330+the area of ​​the exit surface 350). In addition, a light blocking portion 361 may be provided on the bottom surface 360. The light blocking portion 361 may be made of a black material. Thus, the unintended diffuse reflection of light can be suppressed inside the reflective member 300.

[0128] Fig.14 yes Fig. 9 Schematic cross-sectional view of a variation of a camera module.

[0129] Reference Fig.14 At least a portion 120 of the bottom surface of the housing 100 facing the image sensor 810 in the optical axis (Z axis) direction may be inclined relative to the optical axis (Z axis) direction. That is, at least a portion 120 of the bottom surface of the housing 100 may be an inclined surface.

[0130] At least a portion of the third reflective surface 340 may be located between the inclined surface of the housing 100 and the image sensor 810. The third reflective surface 340 and the inclined surface of the housing 100 may be parallel to each other. For example, the inclination angle of the third reflective surface 340 relative to the optical axis (Z axis) direction and the inclination angle of the inclined surface of the housing 100 relative to the optical axis (Z axis) direction may be the same.

[0131] By tilting at least a portion 120 of the bottom surface of the housing 100, it is possible to provide a degree of freedom in installing components in a portable electronic device on which the camera module 1 is installed. For example, since at least a portion 120 of the bottom surface of the housing 100 is tilted, other components to be installed in the portable electronic device can be installed in a space formed by the tilt of the tilted surface. Therefore, the size of the portable electronic device can be further reduced.

[0132] Figure 4 yes Figure 1 and Figure 2 A partially exploded perspective view of the camera module, and Figure 5 yes Figure 2 and Figure 4 A side view of the load-bearing portion.

[0133] The camera module 1 may move the lens module 200 to focus on the object. To this end, the camera module 1 may include a focus adjustment unit 600.

[0134] The focus adjustment unit 600 can move the carrier 400 by generating a driving force in the optical axis (Z axis) direction. Since the lens module 200 is disposed on the carrier 400, the carrier 400 and the lens module 200 can move together in the optical axis (Z axis) direction by the driving force generated by the focus adjustment unit 600. In addition, since the guide frame 500 is disposed on the carrier 400, the guide frame 500 can move together with the carrier 400 in the optical axis (Z axis) direction.

[0135] The focus adjustment unit 600 may include a first magnet 610 and a first coil 630. The first magnet 610 and the first coil 630 may be disposed to face each other in a direction perpendicular to the optical axis (Z axis).

[0136] The first magnet 610 may be mounted on the carrier 400. As an example, the first magnet 610 may be mounted on one side surface of the carrier 400.

[0137] One surface of the first magnet 610 (e.g., the surface facing the first coil 630) may be magnetized to 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 first magnet 610 facing the first coil 630 along the optical axis (Z axis) direction.

[0138] The first coil 630 may be disposed to face the first magnet 610. For example, the first coil 630 may be disposed to face the first magnet 610 in a direction perpendicular to the optical axis (Z axis).

[0139] The first coil 630 may be provided on the substrate 900, and the substrate 900 may be mounted on the housing 100 in such a manner that the first magnet 610 and the first coil 630 face each other in a direction perpendicular to the optical axis (Z axis). As an example, the first coil 630 may be provided on one surface of the substrate 900. The substrate 900 may be mounted on a side surface of the housing 100 in such a manner that the first magnet 610 and the first coil 630 face each other in a direction perpendicular to the optical axis (Z axis).

[0140] The housing 100 may have a through hole penetrating the housing 100 , and the first coil 630 disposed on the substrate 900 may directly face the first magnet 610 through the through hole.

[0141] When adjusting the focus, the first magnet 610 may be a movable member mounted on the carrier 400 and moving in the optical axis (Z axis) direction together with the carrier 400 , and the first coil 630 may be a fixed member fixed to the substrate 900 .

[0142] When power is applied to the first coil 630 , the carrier 400 may move in the optical axis (Z-axis) direction by an electromagnetic force generated between the first magnet 610 and the first coil 630 .

[0143] Since the lens module 200 is disposed on the carrying portion 400 , the lens module 200 can also move in the optical axis (Z-axis) direction through the movement of the carrying portion 400 .

[0144] The first ball member B1 may be disposed between the bearing portion 400 and the housing 100. For example, the first ball member B1 may be disposed between the bearing portion 400 and the housing 100 to reduce friction when the bearing portion 400 moves.

[0145] The first ball member B1 may include a plurality of balls arranged along the optical axis (Z axis) direction. When the bearing portion 400 moves in the optical axis (Z axis) direction, the plurality of balls may move in a rolling manner in the optical axis (Z axis) direction.

[0146] The first ball member B1 may include a first ball group BG1 and a second ball group BG2, and each of the first ball group BG1 and the second ball group BG2 may include one or more balls. The first ball group BG1 and the second ball group BG2 may be disposed to be spaced apart from each other in a direction perpendicular to the optical axis (Z axis).

[0147] The first yoke 650 may be disposed on the housing 100. The first yoke 650 may be disposed at a position facing the first magnet 610. For example, the first coil 630 may be disposed on one surface of the substrate 900, and the first yoke 650 may be disposed on another surface of the substrate 900.

[0148] The first magnet 610 and the first yoke 650 may generate an attractive force therebetween. For example, the first yoke 650 may be made of a magnetic material. The attractive force may act between the first magnet 610 and the first yoke 650 in a direction perpendicular to the optical axis (Z axis).

[0149] Due to the attractive force between the first magnet 610 and the first yoke 650 , the first ball member B1 may maintain contact with each of the bearing portion 400 and the housing 100 .

[0150] The guide grooves may be formed in each of the facing surfaces of the carrier 400 and the housing 100. For example, a first guide groove g1 accommodating the first ball group BG1 and a second guide groove g2 accommodating the second ball group BG2 may be formed in each of the facing surfaces of the carrier 400 and the housing 100.

[0151] Each of the first guide groove g1 and the second guide groove g2 may extend in the optical axis (Z-axis) direction.

[0152] The first ball group BG1 and the second ball group BG2 may be arranged to be spaced apart from each other in the first axis (X axis) direction. The number of balls in the first ball group BG1 and the number of balls in the second ball group BG2 may be different. Specifically, the number of balls included in the first ball group BG1 may be greater than the number of balls included in the second ball group BG2.

[0153] For example, the first ball group BG1 may include two or more balls disposed along the optical axis (Z-axis) direction, and the second ball group BG2 may include a smaller number of balls than the number of balls included in the first ball group BG1.

[0154] Under the premise that the number of balls belonging to the first ball group BG1 and the number of balls belonging to the second ball group BG2 are different, the number of balls belonging to each ball group may be changed. Hereinafter, for convenience of explanation, description will be made based on an embodiment in which the first ball group BG1 includes four balls and the second ball group BG2 includes two balls.

[0155] Among the four balls included in the first ball group BG1, two outermost balls in the optical axis (Z-axis) direction may have the same diameter, and two balls disposed between the two outermost balls may have diameters smaller than those of the outermost balls.

[0156] The two balls included in the second ball group BG2 may have the same diameter.

[0157] Among the four balls included in the first ball group BG1 , each of the two outermost balls in the optical axis (Z-axis) direction may be in contact with the bearing portion 400 at two points and in contact with the housing 100 at two points.

[0158] Each of the two balls in the second ball group BG2 may be in contact with the bearing portion 400 at one point and in contact with the housing 100 at two points (or in contact with the bearing portion 400 at two points and in contact with the housing 100 at one point).

[0159] The first ball group BG1 and the first guide groove g1 can be used as main guides to guide the movement of the bearing part 400 in the optical axis (Z axis) direction, and the second ball group BG2 and the second guide groove g2 can be used as auxiliary guides to support the movement of the bearing part 400 in the optical axis (Z axis) direction.

[0160] The length of the first guide groove g1 in the optical axis (Z axis) direction may be longer than the height of the reflective member 300 in the optical axis (Z axis) direction.

[0161] Either or both of the first ball group BG1 and the second ball group BG2 may be disposed to overlap the reflective member 300 in a direction perpendicular to the optical axis (Z axis) direction. For example, the first ball group BG1 may be disposed to overlap the reflective member 300 in the second axis (Y axis) direction.

[0162] In an embodiment, an auxiliary yoke (not shown) may be provided at a position facing the first magnet 610. For example, the auxiliary yoke may be provided on the substrate 900 to face the first magnet 610. In addition, the auxiliary yoke may be provided on the inner side of the first coil 630.

[0163] The auxiliary yoke may be located closer to the first ball group BG1 than to the second ball group BG2 . The auxiliary yoke may be made of a material capable of generating an attractive force with the first magnet 610 .

[0164] Therefore, the center point of the resultant force of the attraction generated between the first magnet 610 and the first yoke 650 and the attraction generated between the first magnet 610 and the auxiliary yoke may be located closer to the first ball group BG1 than to the second ball group BG2.

[0165] In an embodiment, the camera module 1 may detect the position of the carrier 400 in the optical axis (Z-axis) direction.

[0166] To this end, a first position sensor 670 may be provided. The first position sensor 670 may be provided on the substrate 900 to face the first magnet 610. The first position sensor 670 may be a Hall sensor.

[0167] Figure 6 yes Figure 1 , Figure 2 and Figure 4 A partially exploded perspective view of the camera module. Figure 7 is along Figure 1A sectional perspective view taken along line VII-VII' in FIG. Figure 8 is along Figure 1 A cross-sectional stereogram taken along line VIII-VIII'.

[0168] The camera module 1 can stabilize the optical image by moving the lens module 200 in a direction perpendicular to the optical axis (Z axis) when capturing an image. To this end, the camera module 1 can include an optical image stabilization unit 700 that moves the lens module 200 in a direction perpendicular to the optical axis (Z axis).

[0169] The guide frame 500 and the lens module 200 may be sequentially disposed in the carrier 400. For example, the guide frame 500 may be disposed between the carrier 400 and the lens module 200.

[0170] The guide frame 500 and the lens module 200 can be moved together in one direction perpendicular to the optical axis (Z axis) by a driving force generated by the optical image stabilization unit 700, and the lens module 200 can be moved relative to the guide frame 500 in another direction perpendicular to the optical axis (Z axis) by another driving force generated by the optical image stabilization unit 700.

[0171] For example, the guide frame 500 and the lens module 200 can move together in a first axis (X axis) direction perpendicular to the optical axis (Z axis), and the lens module 200 can move relative to the guide frame 500 in a second axis (Y axis) direction perpendicular to both the optical axis (Z axis) and the first axis (X axis).

[0172] The optical image stabilization unit 700 may include a first sub-stabilization unit 710 and a second sub-stabilization unit 730. The first sub-stabilization unit 710 may generate a driving force in a first axis (X axis) direction, and the second sub-stabilization unit 730 may generate a driving force in a second axis (Y axis) direction.

[0173] The first sub-stabilizing unit 710 may include a second magnet 711 and a second coil 713. The second magnet 711 and the second coil 713 may be disposed to face each other in the first axis (X axis) direction.

[0174] The second magnet 711 may be disposed on the lens module 200. For example, the second magnet 711 may be mounted on one side surface of the bracket 230.

[0175] One surface of the second magnet 711 (eg, a surface facing the second coil 713) may be magnetized to have an N pole or an S pole. The second magnet 711 may have a length extending in the second axis (Y axis) direction.

[0176] The other surface of the second magnet 711 may be magnetized to have a polarity opposite to that of one surface of the second magnet 711 .

[0177] The second coil 713 may be disposed to face the second magnet 711. For example, the second coil 713 may be disposed to face the second magnet 711 in the first axis (X axis) direction.

[0178] The second coil 713 may be disposed on the substrate 900 , and the substrate 900 may be mounted on the housing 100 in such a manner that the second magnet 711 and the second coil 713 face each other in the first axis (X axis) direction.

[0179] The housing 100 may have a through hole penetrating the housing 100 , and the second coil 713 disposed on the substrate 900 may directly face the second magnet 711 through the through hole.

[0180] In stabilizing the optical image, the second magnet 711 may be a movable member mounted on the lens module 200 , and the second coil 713 may be a fixed member fixed to the housing 100 .

[0181] When power is applied to the second coil 713 , the lens module 200 and the guide frame 500 may move in the first axis (X axis) direction by an electromagnetic force generated between the second magnet 711 and the second coil 713 .

[0182] The second magnet 711 and the second coil 713 may generate a driving force in a direction in which they face each other (eg, a first axis (X-axis) direction).

[0183] The second sub-stabilizing unit 730 may include a third magnet 731 and a third coil 733. The third magnet 731 and the third coil 733 may be disposed to face each other in the second axis (Y axis) direction.

[0184] The third magnet 731 may be disposed on the lens module 200. For example, the third magnet 731 may be installed on the other side surface of the bracket 230.

[0185] One surface of the third magnet 731 (eg, a surface facing the third coil 733 ) may be magnetized to have both an N pole and an S pole. The third magnet 731 may have a length extending in the first axis (X axis) direction.

[0186] The other surface of the third magnet 731 may be magnetized to have a polarity opposite to that of one surface of the third magnet 731 .

[0187] The third coil 733 may be disposed to face the third magnet 731. For example, the third coil 733 may be disposed to face the third magnet 731 in the second axis (Y axis) direction.

[0188] The third coil 733 may be disposed on the substrate 900 , and the substrate 900 may be mounted on the housing 100 in such a manner that the third magnet 731 and the third coil 733 face each other in the second axis (Y-axis) direction.

[0189] The housing 100 may have a through hole penetrating the housing 100 , and the third coil 733 disposed on the substrate 900 may directly face the third magnet 731 through the through hole.

[0190] In stabilizing the optical image, the third magnet 731 may be a movable member mounted on the lens module 200 , and the third coil 733 may be a fixed member fixed to the housing 100 .

[0191] When power is applied to the third coil 733 , the lens module 200 may move in the second axis (Y-axis) direction by an electromagnetic force generated between the third magnet 731 and the third coil 733 .

[0192] The third magnet 731 and the third coil 733 may generate a driving force in a direction in which they face each other (eg, a second axis (Y-axis) direction).

[0193] The second magnet 711 and the third magnet 731 may be disposed perpendicularly to each other on a plane perpendicular to the optical axis (Z axis), and the second coil 713 and the third coil 733 may also be disposed perpendicularly to each other on a plane perpendicular to the optical axis (Z axis).

[0194] The camera module 1 according to an embodiment of the present disclosure may include a plurality of ball members supporting the guide frame 500 and the lens module 200. The plurality of ball members may be used to guide the movement of the guide frame 500 and the lens module 200 during the optical image stabilization process. The plurality of ball members may also be used to maintain a gap between the bearing portion 400, the guide frame 500, and the lens module 200.

[0195] The plurality of ball members may include a second ball member B2 and a third ball member B3. The second ball member B2 may be disposed between the bearing portion 400 and the guide frame 500, and the third ball member B3 may be disposed between the guide frame 500 and the lens module 200.

[0196] The second ball member B2 may guide the movement of the guide frame 500 and the lens module 200 in the first axis (X axis) direction, and the third ball member B3 may guide the movement of the lens module 200 in the second axis (Y axis) direction.

[0197] As an example, when a driving force is generated in the first axis (X axis) direction, the second ball member B2 may move in a rolling manner in the first axis (X axis) direction. Therefore, the second ball member B2 may guide the movement of the guide frame 500 and the lens module 200 in the first axis (X axis) direction.

[0198] When a driving force is generated in the second axis (Y axis) direction, the third ball member B3 may move in a rolling manner in the second axis (Y axis) direction. Therefore, the third ball member B3 may guide the movement of the lens module 200 in the second axis (Y axis) direction.

[0199] The second ball member B2 may include a plurality of balls disposed between the bearing portion 400 and the guide frame 500 , and the third ball member B3 may include a plurality of balls disposed between the guide frame 500 and the lens module 200 .

[0200] For example, each of the second ball member B2 and the third ball member B3 may include four balls.

[0201] The third guide groove g3 accommodating the second ball member B2 may be formed in either or both of surfaces of the bearing portion 400 and the guide frame 500 facing each other in the optical axis (Z axis) direction. The third guide groove g3 may include a plurality of grooves corresponding to the plurality of balls of the second ball member B2.

[0202] The second ball member B2 may be received in the third guide groove g3 and inserted between the bearing portion 400 and the guide frame 500 .

[0203] When the second ball member B2 is accommodated in the third guide groove g3, the second ball member B2 can move only in the first axis (X axis) direction, while its movement in the optical axis (Z axis) direction and the second axis (Y axis) direction is restricted. As an example, the second ball member B2 can move only in a rolling manner in the first axis (X axis) direction.

[0204] To this end, a planar shape of each of the plurality of grooves of the third guide grooves g3 may be a rectangle having a length extending in the first axis (X axis) direction.

[0205] The fourth guide groove g4 accommodating the third ball member B3 may be formed in any one or both of the surfaces of the guide frame 500 and the lens module 200 (e.g., the bracket 230) facing each other in the optical axis (Z axis) direction. The fourth guide groove g4 may include a plurality of grooves corresponding to the plurality of balls of the third ball member B3.

[0206] The third ball member B3 may be received in the fourth guide groove g4 and inserted between the guide frame 500 and the lens module 200 .

[0207] When the third ball member B3 is accommodated in the fourth guide groove g4, the third ball member B3 can move only in the second axis (Y axis) direction, while its movement in the optical axis (Z axis) direction and the first axis (X axis) direction is restricted. As an example, the third ball member B3 can move only in the second axis (Y axis) direction in a rolling manner.

[0208] To this end, a planar shape of each of the plurality of grooves of the fourth guide groove g4 may be a rectangle having a length extending in the second axis (Y axis) direction.

[0209] When a driving force is generated in the first axis (X axis) direction, the guide frame 500 and the lens module 200 can move together in the first axis (X axis) direction. Here, the second ball member B2 can move in a rolling manner along the first axis (X axis) direction. At this time, the movement of the third ball member B3 can be restricted.

[0210] When a driving force is generated in the second axis (Y axis) direction, the lens module 200 can move in the second axis (Y axis) direction relative to the guide frame 500. Here, the third ball member B3 can move in a rolling manner along the second axis (Y axis) direction. At this time, the movement of the second ball member B2 can be restricted.

[0211] In an embodiment, the camera module 1 may detect the position of the lens module 200 in a direction perpendicular to the optical axis (Z axis).

[0212] To this end, a second position sensor 715 and a third position sensor 735 may be provided. The second position sensor 715 may be provided on the substrate 900 to face the second magnet 711, and the third position sensor 735 may be provided on the substrate 900 to face the third magnet 731. The second position sensor 715 and the third position sensor 735 may be Hall sensors.

[0213] In the present disclosure, the second yoke 717 and the third yoke 737 may be provided to keep the bearing portion 400 and the guide frame 500 in contact with the second ball member B2 and keep the guide frame 500 and the lens module 200 in contact with the third ball member B3.

[0214] The second yoke 717 and the third yoke 737 may be fixed to the carrier 400 , and may be disposed to face the second magnet 711 and the third magnet 731 , respectively, in the optical axis (Z-axis) direction.

[0215] Therefore, an attractive force can be generated between the second yoke 717 and the second magnet 711 and between the third yoke 737 and the third magnet 731 in the optical axis (Z-axis) direction.

[0216] Due to the attraction generated between the second yoke 717 and the second magnet 711 and the attraction generated between the third yoke 737 and the third magnet 731, the lens module 200 and the guide frame 500 can be pressed in the direction toward the second yoke 717 and the third yoke 737, so that the guide frame 500 and the lens module 200 can be kept in contact with the second ball member B2 and the third ball member B3.

[0217] The second yoke 717 and the third yoke 737 may be made of a material capable of generating an attractive force with the second magnet 711 and the third magnet 731. As an example, the second yoke 717 and the third yoke 737 may be made of a magnetic material.

[0218] The stopper 410 may be coupled to the carrier 400. The stopper 410 may be coupled to the carrier 400 to cover at least a portion of an upper surface of the lens module 200. For example, the stopper 410 may cover at least a portion of an upper surface of the bracket 230.

[0219] The stopper 410 may prevent the guide frame 500 and the lens module 200 from being separated from the carrier 400 due to an external impact or other interference.

[0220] A buffer member (not shown) having an elastic property may be coupled to an edge portion of the stopper 410 .

[0221] In an implementation, at least a portion of the focus adjustment unit 600 may be disposed to overlap the reflective member 300 in a direction perpendicular to the optical axis (Z axis).

[0222] For example, a portion of the first magnet 610 and a portion of the first coil 630 may be disposed to overlap the reflective member 300 in a direction in which the first magnet 610 and the first coil 630 face each other.

[0223] At least a portion of the first magnet 610 may be disposed to be spaced apart from one side surface of the reflective member 300 in the second axis (Y axis) direction. In addition, at least a portion of the first coil 630 may be disposed to be spaced apart from one side surface of the reflective member 300 in the second axis (Y axis) direction. One side surface of the reflective member 300 may have a trapezoidal shape in the second axis (Y axis) direction.

[0224] In an embodiment, at least a portion of the optical image stabilization unit 700 may be disposed to overlap the reflective member 300 in a direction perpendicular to the optical axis (Z axis).

[0225] For example, a portion of the second magnet 711 and a portion of the second coil 713 may be disposed to overlap the reflective member 300 in a direction in which the second magnet 711 and the second coil 713 face each other.

[0226] A portion of the third magnet 731 and a portion of the third coil 733 may be disposed to overlap the reflective member 300 in a direction in which the third magnet 731 and the third coil 733 face each other.

[0227] At least a portion of the second magnet 711 may be disposed to be spaced apart from the first reflective surface 320 of the reflective member 300 in the first axis (X axis) direction. In addition, at least a portion of the second coil 713 may be disposed to be spaced apart from the first reflective surface 320 of the reflective member 300 in the first axis (X axis) direction.

[0228] At least a portion of the third magnet 731 may be disposed to be spaced apart from the other side surface of the reflective member 300 in the second axis (Y axis) direction. In addition, at least a portion of the third coil 733 may be disposed to be spaced apart from the other side surface of the reflective member 300 in the second axis (Y axis) direction. The other side surface of the reflective member 300 may have a trapezoidal shape in the second axis (Y axis) direction.

[0229] Since at least a portion of the focus adjustment unit 600 and at least a portion of the optical image stabilization unit 700 are each arranged to overlap with the reflective member 300 in a direction perpendicular to the optical axis (Z axis), the size of the camera module 1 (e.g., the height in the optical axis (Z axis) direction) can be reduced.

[0230] One edge of the reflective member 300 may be chamfered. Thus, it is possible to prevent one edge of the reflective member 300 from interfering with the inner side surface of the bracket 230. Fig.12 and Fig.13 As shown in FIG. 1 , one edge of the reflective member 300 may be an edge at which the incident surface 310 and the first reflective surface 320 connect to each other.

[0231] Fig.15 is an exploded perspective view of a camera module according to another embodiment of the present disclosure.

[0232] When with reference Figures 1 to 14 The camera module 1 described above is compared to Fig.15 The camera module 2 is different in the presence or absence of a guide frame 500 and the configuration of the optical image stabilization unit 700 .

[0233] For example, in Fig.15 In the camera module 2 of FIG. 4 , the guide frame 500 is not provided between the carrier 400 and the lens module 200. In addition, since the guide frame 500 is not provided, the third ball member B3 provided between the guide frame 500 and the lens module 200 is also not provided.

[0234] The lens module 200 may be configured to be movable in a first axis (X axis) direction and a second axis (Y axis) direction within the carrier 400 .

[0235] The second ball member B2 may be disposed between the carrier 400 and the lens module 200. The second ball member B2 may be disposed to contact each of the carrier 400 and the lens module 200.

[0236] The second ball member B2 can be used to guide the lens module 200 to be movable in two axial directions during the optical image stabilization process. That is, the second ball member B2 can guide the movement of the lens module 200 in the first axis (X axis) direction and the movement in the second axis (Y axis) direction.

[0237] As an example, when a driving force is generated in the first axis (X axis) direction, the second ball member B2 may move in a rolling manner in the first axis (X axis) direction. Therefore, the second ball member B2 may guide the movement of the lens module 200 in the first axis (X axis) direction.

[0238] In addition, when a driving force is generated in the second axis (Y axis) direction, the second ball member B2 may move in a rolling manner in the second axis (Y axis) direction. Therefore, the second ball member B2 may guide the movement of the lens module 200 in the second axis (Y axis) direction.

[0239] The third guide groove g3 accommodating the second ball member B2 may be formed in either one or both surfaces of the bearing portion 400 and the lens module 200 facing each other in the optical axis (Z-axis) direction.

[0240] The second ball member B2 may be disposed in the third guide groove g3 and inserted between the bearing portion 400 and the lens module 200. In a state where the second ball member B2 is accommodated in the third guide groove g3, the second ball member B2 may move in the first axis (X axis) direction and the second axis (Y axis) direction while limiting its movement in the optical axis (Z axis) direction. As an example, the second ball member B2 may move in a rolling manner in the first axis (X axis) direction and the second axis (Y axis) direction.

[0241] The third guide groove g3 may be configured to have a circular cross-sectional shape when cut along a plane perpendicular to the optical axis (Z-axis) direction. The cross-sectional size of the third guide groove g3 may be larger than the diameter of the second ball member B2.

[0242] The second magnet 711 of the first sub-stabilizing unit 710 may include two magnets, and the second coil 713 may include two coils. The two magnets may be disposed to be spaced apart from each other in the second axis (Y axis) direction, and the two coils may also be disposed to be spaced apart from each other in the second axis (Y axis) direction.

[0243] One of the two magnets may face one of the two coils, and the other of the two magnets may face the other of the two coils. Each of the two magnets may be magnetized in such a manner that one surface thereof facing the second coil 713 has one polarity. For example, one surface of one of the two magnets facing one of the two coils may have an N pole, and one surface of the other of the two magnets facing the other of the two coils may have an S pole.

[0244] In another embodiment, although the second coil 713 includes two coils, the second magnet 711 may include one magnet facing the two coils. In this case, one surface of the second magnet 711 facing the two coils may have both an N pole and an S pole, wherein the N pole faces one coil and the S pole faces the other coil.

[0245] The third magnet 731 of the second sub-stabilizing unit 730 may include two magnets, and the third coil 733 may include two coils. The two magnets may be disposed to be spaced apart from each other in the first axis (X axis) direction, and the two coils may also be disposed to be spaced apart from each other in the first axis (X axis) direction.

[0246] One of the two magnets may face one of the two coils, and the other of the two magnets may face the other of the two coils. Each of the two magnets may be magnetized in such a manner that one surface thereof facing the third coil 733 has one polarity. For example, one surface of one of the two magnets facing one of the two coils may have an N pole, and one surface of the other of the two magnets facing the other of the two coils may have an S pole.

[0247] In another embodiment, although the third coil 733 includes two coils, the third magnet 731 may include one magnet facing the two coils. In this case, one surface of the third magnet 731 facing the two coils may have an N pole and an S pole, wherein the N pole faces one coil and the S pole faces the other coil.

[0248] With this structure, magnetic field leakage can be prevented, and sufficient driving force can be generated even at low power.

[0249] In the present embodiment, since the second ball member B2 can move in a rolling manner in the first axis (X-axis) direction and the second axis (Y-axis) direction, when the lens module 200 moves in the first axis (X-axis) direction and the second axis (Y-axis) direction, there is a risk that the lens module 200 may rotate in a plane perpendicular to the optical axis (Z-axis) due to factors such as changes between the driving force applied in the first axis (X-axis) direction and the driving force applied in the second axis (Y-axis) direction.

[0250] Fig.15 The camera module 2 can detect whether the lens module 200 is rotated. In addition, when the lens module 200 is rotated, the camera module 2 can generate a driving force capable of counteracting the rotation of the lens module 200.

[0251] Each of the second position sensor 715 and the third position sensor 735 may include two Hall sensors. When the lens module 200 rotates, the distance between one of the two Hall sensors of the second position sensor 715 and the lens module 200 decreases, and the distance between the other of the two Hall sensors of the second position sensor 715 and the lens module 200 increases (the same applies to the third position sensor 735).

[0252] Therefore, it may be determined by the second position sensor 715 and the third position sensor 735 whether the lens module 200 is rotated.

[0253] exist Fig.15 In the camera module 2 of FIG. 2 , the first sub-stabilizing unit 710 may include a second coil 713 including two coils, and the second sub-stabilizing unit 730 may include a third coil 733 including two coils. Therefore, the first sub-stabilizing unit 710 and the second sub-stabilizing unit 730 may generate a driving force for counteracting the rotation of the lens module 200.

[0254] Despite Fig.15 It has been described in the embodiment that each of the second position sensor 715 and the third position sensor 735 includes two Hall sensors, but it is also feasible that only one of the second position sensor 715 and the third position sensor 735 includes two Hall sensors.

[0255] In addition, only one of the first sub-stabilizing unit 710 and the second sub-stabilizing unit 730 may be configured to have Fig.15 , and the other can be configured to have Figure 2 The form shown in .

[0256] Fig.16 is a perspective view of a camera module according to another embodiment of the present disclosure, and Fig.17 yes Fig.16 An exploded perspective view of the camera module.

[0257] Reference Fig.16 and Fig.17 , a camera module 3 according to another embodiment of the present disclosure may include a lens module 200 , a reflective member 300 , and a housing 100 .

[0258] The lens module 200 may include a lens barrel 210 and a bracket 230. The lens barrel 210 may have a hollow cylindrical shape, and at least one lens for imaging an object may be accommodated inside the lens barrel 210. In the case where a plurality of lenses are arranged, the plurality of lenses may be installed inside the lens barrel 210 along the optical axis (Z axis).

[0259] The lens barrel 210 may be coupled to the bracket 230. The lens barrel 210 and the bracket 230 may move together.

[0260] The housing 100 may have an internal space. In an embodiment, the housing 100 may be shaped like a quadrilateral (e.g., rectangular) box. An opening 130 may be formed in one surface of the housing 100. The internal space of the housing 100 may be exposed to the outside of the housing 100 through the opening 130. One surface of the housing 100 may be as shown in FIG. Fig.17 The upper surface of the housing 100 is shown in FIG.

[0261] The reflective member 300 may be disposed in the inner space of the housing 100. In addition, the lens module 200 may be disposed in front of the reflective member 300. Here, the expression "in front of" may refer to a positive optical axis (Z axis) direction (+Z axis direction) relative to the reflective member 300. For example, the lens module 200 may be spaced apart upward from the reflective member 300 in the optical axis (Z axis) direction.

[0262] Therefore, light may be incident on the reflective member 300 after passing through the lens module 200 .

[0263] The lens module 200 may be moved in one or more of three axial directions intersecting each other. In addition, the lens module 200 may be moved relative to the reflective member 300.

[0264] For example, the lens module 200 may be moved in the direction of the optical axis (Z axis) for focus adjustment. In addition, the lens module 200 may be moved in a direction perpendicular to the optical axis (Z axis) for optical image stabilization.

[0265] In an embodiment, the three axial directions intersecting each other may be an optical axis (Z-axis) direction, a first axis (X-axis) direction, and a second axis (Y-axis) direction.

[0266] The camera module 3 may further include a carrier 400 and a guide frame 500 .

[0267] The carrier 400 may be disposed inside the housing 100 , and may be movable relative to the housing 100 in the optical axis (Z-axis) direction.

[0268] The lens module 200 may be disposed on the carrier 400, and the carrier 400 and the lens module 200 may move together in the optical axis (Z axis) direction. Therefore, the camera module 3 may adjust the focus.

[0269] In addition, the lens module 200 may move in a direction perpendicular to the optical axis (Z-axis) direction to stabilize an optical image when capturing an image.

[0270] The guide frame 500 may be disposed between the carrier 400 and the lens module 200. The guide frame 500 may be used to guide the lens module 200 to be movable in a direction perpendicular to the optical axis (Z-axis) direction.

[0271] The guide frame 500 may be a quadrilateral (eg, rectangular) frame having an opening in the optical axis (Z-axis) direction. In an embodiment, the planar shape of the guide frame 500 may be approximately shape.

[0272] The bearing portion 400 and the guide frame 500 may be disposed in front of the reflective member 300. That is, the bearing portion 400 and the guide frame 500 may be disposed to be higher than the reflective member 300 in the optical axis (Z-axis) direction.

[0273] The lens module 200 may be accommodated in the housing 100. For example, the lens module 200 may be disposed inside the opening 130 formed in one surface of the housing 100. In an embodiment, the carrier 400 may be disposed inside the housing 100, and the lens module 200 may be accommodated inside the carrier 400.

[0274] The camera module 3 may adjust the focus by moving the lens module 200 in the optical axis (Z axis) direction, and may stabilize the optical image by moving the lens module 200 in a direction perpendicular to the optical axis (Z axis) when capturing an image.

[0275] The camera module 3 may further include a focus adjustment unit 600 that moves the lens module 200 in the optical axis (Z axis) direction and an optical image stabilization unit 700 that moves the lens module 200 in a direction perpendicular to the optical axis (Z axis) direction.

[0276] The camera module 3 may further include an image sensor module 800 and a housing 110 .

[0277] Reference Fig.10 and Fig.11 , the image sensor module 800 may include an image sensor 810 and a printed circuit board 830 connected to the image sensor 810 , and may further include a sensor housing 850 .

[0278] The image sensor 810 may convert light incident 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.

[0279] The electrical signal converted by the image sensor 810 may be output as an image through a display unit of a portable electronic device on which the camera module 3 is mounted.

[0280] 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.

[0281] The image sensor 810 may have an imaging surface on which light is received, and the imaging surface of the image sensor 810 may be a surface intersecting with the optical axis (Z axis) direction. The image sensor 810 may be disposed to be spaced apart from the reflective member 300. For example, the image sensor 810 may be spaced apart upward from the reflective member 300 in the optical axis (Z axis) direction.

[0282] In an embodiment, both the lens module 200 and the image sensor 810 may be disposed higher in the optical axis (Z-axis) direction than the reflective member 300. For example, the lens module 200 and the image sensor 810 may be disposed closer to the object than the reflective member 300. That is, among the lens module 200, the image sensor 810, and the reflective member 300, the lens module 200 and the image sensor 810 may be those closest to the object, and the reflective member 300 may be the one farthest from the object.

[0283] The image sensor module 800 may be mounted in the housing 100. As an example, the image sensor module 800 may be disposed in an opening 130 formed in one surface of the housing 100.

[0284] In an embodiment, the sensor housing 850 may be coupled to the printed circuit board 830, and the image sensor 810 may be disposed in an inner space of the sensor housing 850. In addition, either or both of the sensor housing 850 and the printed circuit board 830 may be coupled to the housing 100.

[0285] The lens module 200 and the image sensor 810 may be disposed in the opening 130 of the housing 100 , and may be disposed to be spaced apart from each other in a direction intersecting the optical axis (Z axis) direction, for example, a first axis (X axis) direction.

[0286] The housing 110 may be coupled to the case 100 to cover an outer surface of the case 100 , and may play a role in protecting internal components of the camera module 3 .

[0287] The reflective member 300 may have one surface facing the optical axis (Z axis) direction. One surface of the reflective member 300 may be a surface intersecting the optical axis (Z axis) direction. As an example, one surface of the reflective member 300 may be as follows: Fig.17 The upper surface of the reflective member 300 is shown in FIG.

[0288] The lens module 200 and the image sensor 810 may be disposed closer to the object than the reflective member 300, and may be spaced apart from each other in a direction intersecting the optical axis (Z-axis) direction. That is, among the lens module 200, the image sensor 810, and the reflective member 300, the lens module 200 and the image sensor 810 may be those closest to the object, and the reflective member 300 may be the one farthest from the object.

[0289] In an implementation, the lens module 200 may face a portion of one surface (eg, upper surface) of the reflective member 300 , and the image sensor 810 may face another portion of the one surface (eg, upper surface) of the reflective member 300 .

[0290] The reflective member 300 may have one or more reflective surfaces. Since the light having passed through the lens module 200 enters the image sensor 810 after being reflected by the reflective member 300, a long optical path may be formed within a limited space.

[0291] In addition, since the lens module 200 is disposed in front of the reflective member 300, the Fno (F number) of the camera module 3 may be reduced to capture a bright image.

[0292] Reference Fig.12 In an embodiment, the reflective member 300 may be in the form of a trapezoidal prism. The reflective member 300 may include an incident surface 310 into which light is incident, a first reflective surface 320 that reflects light that has passed through the incident surface 310, a second reflective surface 330 that reflects light reflected from the first reflective surface 320, a third reflective surface 340 that reflects light reflected from the second reflective surface 330, and an exit surface 350 that emits light reflected from the third reflective surface 340. The light that has passed through the exit surface 350 may be incident on the image sensor 810.

[0293] That the image sensor 810 is disposed closer to the object than the reflective member 300 may mean that the image sensor 810 is disposed closer to the object than the exit surface 350 of the reflective member 300 .

[0294] The incident surface 310, the second reflective surface 330, and the exit surface 350 may be one surface extending on the same plane.

[0295] Each of the first reflective surface 320 and the third reflective surface 340 may be inclined with respect to the second reflective surface 330 .

[0296] A portion of the reflective member 300 may be disposed in the inner space of the carrier 400. In an implementation, the incident surface 310 and the first reflective surface 320 of the reflective member 300 may be disposed in the inner space of the carrier 400.

[0297] Fig.23 yes Fig.16 Schematic cross-sectional view of a camera module.

[0298] Reference Fig.23 At least a portion 120 of the bottom surface of the housing 100 facing the image sensor 810 in the optical axis (Z axis) direction may be inclined relative to the optical axis (Z axis) direction. That is, at least a portion 120 of the bottom surface of the housing 100 may be an inclined surface.

[0299] At least a portion of the third reflective surface 340 may be located between the inclined surface of the housing 100 and the image sensor 810. The third reflective surface 340 and the inclined surface of the housing 100 may be parallel to each other. For example, the inclination angle of the third reflective surface 340 relative to the optical axis (Z axis) direction and the inclination angle of the inclined surface of the housing 100 relative to the optical axis (Z axis) direction may be the same.

[0300] Fig.18 yes Fig.16 and Fig.17 A partially exploded perspective view of the camera module. Fig.19 yes Fig.17 and Fig.18 A side view of the load-bearing portion, and Fig. 20 is along Fig.18 The line XX-XX' in Fig.16 and Fig.17 A cross-sectional view of the shell.

[0301] The camera module 3 may move the lens module 200 to focus on the object. To this end, the camera module 3 may include a focus adjustment unit 600.

[0302] The focus adjustment unit 600 can move the carrier 400 by generating a driving force in the optical axis (Z axis) direction. Since the lens module 200 is disposed on the carrier 400, the carrier 400 and the lens module 200 can move together in the optical axis (Z axis) direction by the driving force generated by the focus adjustment unit 600. In addition, since the guide frame 500 is disposed on the carrier 400, the guide frame 500 can move together with the carrier 400 in the optical axis (Z axis) direction.

[0303] The focus adjustment unit 600 may include a first magnet 610 and a first coil 630. The first magnet 610 and the first coil 630 may be disposed to face each other in a direction perpendicular to the optical axis (Z axis).

[0304] The first magnet 610 may be mounted on the carrier 400. As an example, the first magnet 610 may be mounted on one side surface of the carrier 400. A back yoke (not shown) may be provided between one side surface of the carrier 400 and the first magnet 610. The back yoke may be made of a magnetic material. The back yoke makes it possible to prevent the magnetic field of the first magnet 610 from leaking into the carrier 400.

[0305] One surface of the first magnet 610 (e.g., the surface facing the first coil 630) may be magnetized to 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 first magnet 610 facing the first coil 630 along the optical axis (Z axis) direction.

[0306] The first coil 630 may be disposed to face the first magnet 610. For example, the first coil 630 may be disposed to face the first magnet 610 in a direction perpendicular to the optical axis (Z axis).

[0307] The first coil 630 may be provided on the substrate 900, and the substrate 900 may be mounted on the housing 100 in such a manner that the first magnet 610 and the first coil 630 face each other in a direction perpendicular to the optical axis (Z axis). As an example, the first coil 630 may be provided on one surface of the substrate 900. The substrate 900 may be mounted on a side surface of the housing 100 in such a manner that the first magnet 610 and the first coil 630 face each other in a direction perpendicular to the optical axis (Z axis).

[0308] The housing 100 may have a through hole penetrating the housing 100 , and the first coil 630 disposed on the substrate 900 may directly face the first magnet 610 through the through hole.

[0309] When adjusting the focus, the first magnet 610 may be a movable member mounted on the carrier 400 and moving in the optical axis (Z axis) direction together with the carrier 400 , and the first coil 630 may be a fixed member fixed to the substrate 900 .

[0310] When power is applied to the first coil 630 , the carrier 400 may move in the optical axis (Z-axis) direction by an electromagnetic force generated between the first magnet 610 and the first coil 630 .

[0311] Since the lens module 200 is disposed on the carrying portion 400 , the lens module 200 can also move in the optical axis (Z-axis) direction through the movement of the carrying portion 400 .

[0312] The first ball member B1 may be disposed between the bearing portion 400 and the housing 100. For example, the first ball member B1 may be disposed between the bearing portion 400 and the housing 100 to reduce friction when the bearing portion 400 moves.

[0313] The first ball member B1 may include a plurality of balls arranged along the optical axis (Z axis) direction. When the bearing portion 400 moves in the optical axis (Z axis) direction, the plurality of balls may move in a rolling manner in the optical axis (Z axis) direction.

[0314] The first ball member B1 may include a first ball group BG1 and a second ball group BG2, and each of the first ball group BG1 and the second ball group BG2 may include one or more balls. The first ball group BG1 and the second ball group BG2 may be disposed to be spaced apart from each other in a direction perpendicular to the optical axis (Z axis).

[0315] The first yoke 650 may be disposed on the housing 100. The first yoke 650 may be disposed at a position facing the first magnet 610. For example, the first coil 630 may be disposed on one surface of the substrate 900, and the first yoke 650 may be disposed on another surface of the substrate 900.

[0316] The first magnet 610 and the first yoke 650 may generate an attractive force therebetween. For example, the first yoke 650 may be made of a magnetic material. The attractive force may act between the first magnet 610 and the first yoke 650 in a direction perpendicular to the optical axis (Z axis).

[0317] Due to the attractive force generated between the first magnet 610 and the first yoke 650 , the first ball member B1 may come into contact with each of the bearing portion 400 and the housing 100 .

[0318] The guide grooves may be formed in each of the facing surfaces of the carrier 400 and the housing 100. For example, a first guide groove g1 accommodating the first ball group BG1 and a second guide groove g2 accommodating the second ball group BG2 may be formed in each of the facing surfaces of the carrier 400 and the housing 100.

[0319] Each of the first guide groove g1 and the second guide groove g2 may extend in the optical axis (Z-axis) direction.

[0320] The first ball group BG1 and the second ball group BG2 may be arranged to be spaced apart from each other in the second axis (Y axis) direction. The number of balls in the first ball group BG1 and the number of balls in the second ball group BG2 may be different. Specifically, the number of balls included in the first ball group BG1 may be greater than the number of balls included in the second ball group BG2.

[0321] For example, the first ball group BG1 may include two or more balls disposed along the optical axis (Z-axis) direction, and the second ball group BG2 may include a smaller number of balls than the number of balls included in the first ball group BG1.

[0322] Under the premise that the number of balls belonging to the first ball group BG1 and the number of balls belonging to the second ball group BG2 are different, the number of balls belonging to each ball group may be changed. Hereinafter, for convenience of explanation, description will be made based on an embodiment in which the first ball group BG1 includes two balls and the second ball group BG2 includes one ball.

[0323] Each of the two balls in the first ball group BG1 may be in contact with the bearing portion 400 at two points and in contact with the housing 100 at two points.

[0324] One ball in the second ball group BG2 may be in contact with the bearing portion 400 at one point and in contact with the housing 100 at two points (or in contact with the bearing portion 400 at two points and in contact with the housing 100 at one point).

[0325] The first ball group BG1 and the first guide groove g1 can be used as main guides to guide the movement of the bearing part 400 in the optical axis (Z axis) direction, and the second ball group BG2 and the second guide groove g2 can be used as auxiliary guides to support the movement of the bearing part 400 in the optical axis (Z axis) direction.

[0326] The length of the first guide groove g1 of the bearing portion 400 in the optical axis (Z axis) direction may be longer than the height of the reflective member 300 in the optical axis (Z axis) direction.

[0327] Either or both of the first ball group BG1 and the second ball group BG2 may be disposed to overlap the reflective member 300 in a direction perpendicular to the optical axis (Z axis) direction. For example, each of the first ball group BG1 and the second ball group BG2 may be disposed to at least partially overlap the reflective member 300 in the first axis (X axis) direction.

[0328] In an embodiment, an auxiliary yoke (not shown) may be provided at a position facing the first magnet 610. For example, the auxiliary yoke may be provided on the substrate 900 to face the first magnet 610. In addition, the auxiliary yoke may be provided on the inner side of the first coil 630.

[0329] The auxiliary yoke may be located closer to the first ball group BG1 than to the second ball group BG2 . The auxiliary yoke may be made of a material capable of generating an attractive force with the first magnet 610 .

[0330] Therefore, the center point of the resultant force of the attraction generated between the first magnet 610 and the first yoke 650 and the attraction generated between the first magnet 610 and the auxiliary yoke may be located closer to the first ball group BG1 than to the second ball group BG2.

[0331] In an embodiment, the camera module 3 may detect the position of the carrier 400 in the optical axis (Z-axis) direction.

[0332] To this end, a first position sensor 670 may be provided. The first position sensor 670 may be provided on the substrate 900 to face the first magnet 610. The first position sensor 670 may be a Hall sensor.

[0333] Fig.21 It is shown Fig.17 An exploded perspective view of the load-bearing part, the guide frame and the bracket.

[0334] The camera module 3 can stabilize the optical image by moving the lens module 200 in a direction perpendicular to the optical axis (Z axis) when capturing an image. To this end, the camera module 3 can include an optical image stabilization unit 700 that moves the lens module 200 in a direction perpendicular to the optical axis (Z axis).

[0335] The guide frame 500 and the lens module 200 may be sequentially received in the carrier 400. For example, the guide frame 500 may be disposed between the carrier 400 and the lens module 200.

[0336] In an embodiment, the carrier 400 may have a first internal space 410 and a second internal space 420. The first internal space 410 and the second internal space 420 may be arranged to be spaced apart from each other in the optical axis (Z axis) direction. The carrier 400 may have a bottom surface that separates the first internal space 410 and the second internal space 420 from each other. The bottom surface may have a through hole through which light passes.

[0337] The guide frame 500 and the lens module 200 may be disposed in the first inner space 410 of the carrier 400 , and a portion of the reflective member 300 may be disposed in the second inner space 420 of the carrier 400 .

[0338] The guide frame 500 and the lens module 200 can be moved together in one direction perpendicular to the optical axis (Z axis) by the driving force generated by the optical image stabilization unit 700, and the lens module 200 can be moved relative to the guide frame 500 in another direction perpendicular to the optical axis (Z axis) by the driving force generated by the optical image stabilization unit 700.

[0339] For example, the guide frame 500 and the lens module 200 can move together in a first axis (X axis) direction perpendicular to the optical axis (Z axis), and the lens module 200 can move relative to the guide frame 500 in a second axis (Y axis) direction perpendicular to both the optical axis (Z axis) and the first axis (X axis).

[0340] The optical image stabilization unit 700 may include a first sub-stabilization unit 710 and a second sub-stabilization unit 730.

That is, the optical image stabilization unit 700 may be disposed to be higher than the reflective member 300 in the optical axis (Z axis) direction.

[0341] The first sub-stabilizing unit 710 may include a second magnet 711 and a second coil 713. The second magnet 711 and the second coil 713 may be disposed to face each other in the first axis (X axis) direction.

[0342] The second magnet 711 may be disposed on the lens module 200. For example, the second magnet 711 may be mounted on one side surface of the bracket 230.

[0343] One surface of the second magnet 711 (eg, a surface facing the second coil 713) may be magnetized to have an N pole or an S pole. The second magnet 711 may have a length extending in the second axis (Y axis) direction.

[0344] The other surface of the second magnet 711 may be magnetized to have a polarity opposite to that of one surface of the second magnet 711 .

[0345] The second coil 713 may be disposed to face the second magnet 711. For example, the second coil 713 may be disposed to face the second magnet 711 in the first axis (X axis) direction.

[0346] The second coil 713 may be disposed on the substrate 900 , and the substrate 900 may be mounted on the housing 100 in such a manner that the second magnet 711 and the second coil 713 face each other in the first axis (X axis) direction.

[0347] The housing 100 may have a through hole, and the second coil 713 disposed on the substrate 900 may directly face the second magnet 711 through the through hole.

[0348] The through hole in which the first coil 630 is provided and the through hole in which the second coil 713 is provided may be provided to be spaced apart in the optical axis (Z-axis) direction.

[0349] The first magnet 610 of the focus adjustment unit 600 and the second magnet 711 of the optical image stabilization unit 700 may be disposed to be spaced apart from each other in the optical axis (Z axis) direction. In addition, the first coil 630 and the second coil 713 may also be disposed to be spaced apart from each other in the optical axis (Z axis) direction.

[0350] In stabilizing the optical image, the second magnet 711 may be a movable member mounted on the lens module 200 , and the second coil 713 may be a fixed member fixed to the housing 100 .

[0351] When power is applied to the second coil 713 , the lens module 200 and the guide frame 500 may move in the first axis (X axis) direction by an electromagnetic force generated between the second magnet 711 and the second coil 713 .

[0352] The second magnet 711 and the second coil 713 may generate a driving force in a direction in which they face each other (eg, a first axis (X-axis) direction).

[0353] The second sub-stabilizing unit 730 may include a third magnet 731 and a third coil 733. The third magnet 731 and the third coil 733 may be disposed to face each other in the second axis (Y axis) direction.

[0354] The third magnet 731 may be disposed on the lens module 200. For example, the third magnet 731 may be installed on the other side surface of the bracket 230.

[0355] One surface of the third magnet 731 (eg, a surface facing the third coil 733 ) may be magnetized to have an S pole or an N pole. The third magnet 731 may have a length extending in the first axis (X axis) direction.

[0356] The other surface of the third magnet 731 may be magnetized to have a polarity opposite to that of one surface of the third magnet 731 .

[0357] The third coil 733 may be disposed to face the third magnet 731. For example, the third coil 733 may be disposed to face the third magnet 731 in the second axis (Y axis) direction.

[0358] The third coil 733 may be disposed on the substrate 900 , and the substrate 900 may be mounted on the housing 100 in such a manner that the third magnet 731 and the third coil 733 face each other in the second axis (Y-axis) direction.

[0359] The housing 100 may have a through hole, and the third coil 733 disposed on the substrate 900 may directly face the third magnet 731 through the through hole.

[0360] In stabilizing the optical image, the third magnet 731 may be a movable member mounted on the lens module 200 , and the third coil 733 may be a fixed member fixed to the housing 100 .

[0361] When power is applied to the third coil 733 , the lens module 200 may move in the second axis (Y-axis) direction by an electromagnetic force generated between the third magnet 731 and the third coil 733 .

[0362] The third magnet 731 and the third coil 733 may generate a driving force in a direction in which they face each other (eg, a second axis (Y-axis) direction).

[0363] The second magnet 711 and the third magnet 731 may be disposed perpendicularly to each other on a plane perpendicular to the optical axis (Z axis), and the second coil 713 and the third coil 733 may also be disposed perpendicularly to each other on a plane perpendicular to the optical axis (Z axis).

[0364] In an embodiment, the third magnet 731 may include two magnets disposed in the second axis (Y axis) direction and spaced apart from each other, and the third coil 733 may include two coils disposed in the second axis (Y axis) direction and spaced apart from each other. However, the third magnet 731 and the third coil 733 are not limited thereto, and the third magnet 731 may be formed as one magnet and the third coil 733 may be formed as one coil.

[0365] The camera module 3 according to another embodiment of the present disclosure may include a plurality of ball members supporting the guide frame 500 and the lens module 200. The plurality of ball members may be used to guide the movement of the guide frame 500 and the lens module 200 during the optical image stabilization process. The plurality of ball members may also be used to maintain a gap between the bearing portion 400, the guide frame 500, and the lens module 200.

[0366] The plurality of ball members may include a second ball member B2 and a third ball member B3. The second ball member B2 may be disposed between the bearing portion 400 and the guide frame 500, and the third ball member B3 may be disposed between the guide frame 500 and the lens module 200.

[0367] The second ball member B2 may guide the movement of the guide frame 500 and the lens module 200 in the first axis (X axis) direction, and the third ball member B3 may guide the movement of the lens module 200 in the second axis (Y axis) direction.

[0368] As an example, when a driving force is generated in the first axis (X axis) direction, the second ball member B2 may move in a rolling manner in the first axis (X axis) direction. Therefore, the second ball member B2 may guide the movement of the guide frame 500 and the lens module 200 in the first axis (X axis) direction.

[0369] When a driving force is generated in the second axis (Y axis) direction, the third ball member B3 may move in a rolling manner in the second axis (Y axis) direction. Therefore, the third ball member B3 may guide the movement of the lens module 200 in the second axis (Y axis) direction.

[0370] The second ball member B2 may include a plurality of balls disposed between the bearing portion 400 and the guide frame 500 , and the third ball member B3 may include a plurality of balls disposed between the guide frame 500 and the lens module 200 .

[0371] For example, each of the second ball member B2 and the third ball member B3 may include four balls.

[0372] The third guide groove g3 accommodating the second ball member B2 may be formed in either or both of surfaces of the bearing portion 400 and the guide frame 500 facing each other in the optical axis (Z axis) direction. The third guide groove g3 may include a plurality of grooves corresponding to the plurality of balls of the second ball member B2.

[0373] The second ball member B2 may be received in the third guide groove g3 and inserted between the bearing portion 400 and the guide frame 500 .

[0374] When the second ball member B2 is accommodated in the third guide groove g3, the second ball member B2 can move only in the first axis (X axis) direction, while its movement in the optical axis (Z axis) direction and the second axis (Y axis) direction is restricted. As an example, the second ball member B2 can move only in a rolling manner in the first axis (X axis) direction.

[0375] To this end, a planar shape of each of the plurality of grooves of the third guide grooves g3 may be a rectangle having a length extending in the first axis (X axis) direction.

[0376] The fourth guide groove g4 accommodating the third ball member B3 may be formed in any one or both of the surfaces of the guide frame 500 and the lens module 200 (e.g., the bracket 230) facing each other in the optical axis (Z axis) direction. The fourth guide groove g4 may include a plurality of grooves corresponding to the plurality of balls of the third ball member B3.

[0377] The third ball member B3 may be received in the fourth guide groove g4 and inserted between the guide frame 500 and the lens module 200 .

[0378] When the third ball member B3 is accommodated in the fourth guide groove g4, the third ball member B3 can move only in the second axis (Y axis) direction, while its movement in the optical axis (Z axis) direction and the first axis (X axis) direction is restricted. As an example, the third ball member B3 can move only in the second axis (Y axis) direction in a rolling manner.

[0379] To this end, a planar shape of each of the plurality of grooves of the fourth guide groove g4 may be a rectangle having a length extending in the second axis (Y axis) direction.

[0380] When a driving force is generated in the first axis (X axis) direction, the guide frame 500 and the lens module 200 can move together in the first axis (X axis) direction. Here, the second ball member B2 can move in a rolling manner along the first axis (X axis) direction. At this time, the movement of the third ball member B3 can be restricted.

[0381] When a driving force is generated in the second axis (Y axis) direction, the lens module 200 can move in the second axis (Y axis) direction relative to the guide frame 500. Here, the third ball member B3 can move in a rolling manner along the second axis (Y axis) direction. At this time, the movement of the second ball member B2 can be restricted.

[0382] In an embodiment, the camera module 3 may detect the position of the lens module 200 in a direction perpendicular to the optical axis (Z axis).

[0383] To this end, a second position sensor 715 and a third position sensor 735 may be provided. The second position sensor 715 may be provided on the substrate 900 to face the second magnet 711, and the third position sensor 735 may be provided on the substrate 900 to face the third magnet 731. The second position sensor 715 and the third position sensor 735 may be Hall sensors.

[0384] In the present disclosure, a second yoke (not shown) and a third yoke (not shown) may be provided to keep the bearing portion 400 and the guide frame 500 in contact with the second ball member B2 and to keep the guide frame 500 and the lens module 200 in contact with the third ball member B3.

[0385] The second and third yokes may be fixed to the carrier 400 and disposed to face the second and third magnets 711 and 731 in the optical axis (Z axis) direction, respectively.

[0386] Therefore, an attractive force can be generated between the second yoke and the second magnet 711 and between the third yoke and the third magnet 731 in the optical axis (Z-axis) direction.

[0387] Due to the attraction generated between the second yoke and the second magnet 711 and the attraction generated between the third yoke and the third magnet 731, the lens module 200 and the guide frame 500 can be pressed in the direction toward the second yoke and the third yoke, so that the guide frame 500 and the lens module 200 can be kept in contact with the second ball member B2 and the third ball member B3.

[0388] The second and third yokes may be made of a material capable of generating an attractive force with the second and third magnets 711 and 731. As an example, the second and third yokes may be made of a magnetic material.

[0389] Reference Fig.17 , 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 the upper surface of the lens module 200. For example, the stopper 430 may cover at least a portion of the upper surface of the bracket 230.

[0390] The stopper 430 may prevent the guide frame 500 and the lens module 200 from being separated from the carrier 400 due to external impact or other interference.

[0391] A buffer member (not shown) having an elastic property may be coupled to an edge portion of the stopper 430 .

[0392] Fig. 22 is a diagram showing the housing and image sensor module with Fig.16 A perspective view of a state in which a camera module is separated and an image sensor module is shown in a bottom perspective view. Fig.23 yes Fig.16 Schematic cross-sectional view of a camera module.

[0393] Reference Fig. 22 and Fig.23 , the upper surface of the housing 100 may have a step. In an embodiment, the housing 100 may include a first upper surface 101 and a second upper surface 102. The first upper surface 101 may be disposed at a higher position than the second upper surface 102 in the positive optical axis (Z axis) direction.

[0394] The lens module 200 may be disposed in an area defined by the first upper surface 101. In addition, a portion of the image sensor module 800 may be disposed in an area defined by the first upper surface 101. The other portion of the image sensor module 800 may be disposed in an area defined by the second upper surface 102.

[0395] Each of an area defined by the first upper surface 101 and an area defined by the second upper surface 102 may be a portion of an inner space of the housing 100 .

[0396] Since a portion of the image sensor module 800 is located within the region defined by the first upper surface 101 , the length of the reflective member 300 in the first axis (X-axis) direction may be reduced.

[0397] In an implementation, a portion of the image sensor 810 may be disposed in the second inner space 420 of the carrier 400 .

[0398] In an implementation, at least a portion of the focus adjustment unit 600 may be disposed to overlap the reflective member 300 in a direction perpendicular to the optical axis (Z axis).

[0399] For example, a portion of the first magnet 610 and a portion of the first coil 630 may be disposed to overlap the reflective member 300 in a direction in which the first magnet 610 and the first coil 630 face each other.

[0400] At least a portion of the first magnet 610 may be disposed to be spaced apart from the first reflective surface 320 of the reflective member 300 in the first axis (X axis) direction. In addition, at least a portion of the first coil 630 may be disposed to be spaced apart from the first reflective surface 320 of the reflective member 300 in the first axis (X axis) direction.

[0401] The optical image stabilization unit 700 may be disposed higher than the reflective member 300 in the optical axis (Z-axis) direction.

[0402] Since at least a portion of the focus adjustment unit 600 is configured to overlap with the reflective member 300 in a direction perpendicular to the optical axis (Z axis), and the optical image stabilization unit 700 is configured to be higher than the reflective member 300 in the direction of the optical axis (Z axis), the size of the camera module 3 (for example, the length in a direction perpendicular to the optical axis (Z axis)) can be reduced.

[0403] Fig.24 is an exploded perspective view of a camera module according to another embodiment of the present disclosure.

[0404] When with reference Figures 16 to 23 The camera module 3 described above is compared to Fig.24 The camera module 4 is different in the presence or absence of a guide frame 500 and the configuration of the optical image stabilization unit 700 .

[0405] For example, in Fig.24 In the camera module 4, the guide frame 500 is not provided between the carrier 400 and the lens module 200. In addition, since the guide frame 500 is not provided, the third ball member B3 provided between the guide frame 500 and the lens module 200 is also not provided.

[0406] Because of the use Fig.24 The configuration of the optical image stabilization unit 700 of the camera module 4 is similar to that of the reference Fig.15 The configuration of the camera module 2 is not described, and thus a detailed description thereof will be omitted.

[0407] Fig.25 is an exploded perspective view of a camera module according to another embodiment of the present disclosure, and Fig.26 yes Fig.25 A plan view of a connection substrate of a camera module.

[0408] Reference Fig.25 , a camera module 5 according to another embodiment of the present disclosure may include a lens module 200 , a reflective member 300 , and a housing 100 .

[0409] The lens module 200 may include a lens barrel 210 and a bracket 230. The lens barrel 210 may have a hollow cylindrical shape, and at least one lens for imaging an object may be accommodated inside the lens barrel 210. In the case where a plurality of lenses are arranged, the plurality of lenses may be installed inside the lens barrel 210 along the optical axis (Z axis).

[0410] The lens barrel 210 may move in one or more of three axial directions intersecting each other.

[0411] The lens barrel 210 may be coupled to the bracket 230. The lens barrel 210 and the bracket 230 may move together.

[0412] The housing 100 may have an internal space. In an embodiment, the housing 100 may be shaped like a quadrilateral (eg, rectangular) box. An opening 130 may be formed in one surface of the housing 100. The internal space of the housing 100 may be exposed to the outside of the housing 100 through the opening 130. One surface of the housing 100 may be Fig.25 The upper surface of the shell 100 in the embodiment of the present invention.

[0413] The reflective member 300 may be disposed in the internal space of the housing 100. In addition, the lens barrel 210 of the lens module 200 may be disposed in front of the reflective member 300. Here, the expression "in front of" may refer to a positive optical axis (Z axis) direction (+Z axis direction) relative to the reflective member 300. For example, the lens barrel 210 may be spaced apart upward from the reflective member 300 in the optical axis (Z axis) direction.

[0414] Therefore, light may be incident on the reflective member 300 after passing through the lens barrel 210 .

[0415] The lens module 200 may be moved in one or more of three axial directions intersecting each other. In addition, the lens module 200 may be moved relative to the reflective member 300.

[0416] For example, the lens module 200 may be moved in the direction of the optical axis (Z axis) for focus adjustment. In addition, the lens module 200 may be moved in a direction perpendicular to the optical axis (Z axis) for optical image stabilization.

[0417] In an embodiment, the three axial directions intersecting each other may be an optical axis (Z-axis) direction, a first axis (X-axis) direction, and a second axis (Y-axis) direction.

[0418] The camera module 5 may further include a carrying portion 400 ′ and a guide frame 500 .

[0419] The bearing portion 400' and the guide frame 500 may be disposed inside the housing 100 and each may move relative to the housing 100 in a direction perpendicular to the optical axis (Z axis). Since the reflective member 300 is fixed to the housing 100, the bearing portion 400' and the guide frame 500 may also move relative to the reflective member 300.

[0420] The carrier 400 ′ and the guide frame 500 may be disposed in the inner space of the housing 100 , and the lens module 200 may be accommodated in the carrier 400 ′.

[0421] The guide frame 500 may be disposed in the inner space of the housing 100 , and the bearing portion 400 ′ may be disposed on the guide frame 500 .

[0422] The carrier 400' and the lens module 200 may move together in a direction perpendicular to the optical axis (Z-axis) direction. Therefore, the camera module 5 may stabilize an optical image when capturing an image.

[0423] In addition, the lens module 200 may be disposed inside the carrier 400' in the optical axis (Z axis) direction. Therefore, the camera module 5 may adjust the focus.

[0424] The guide frame 500 may be a quadrilateral (eg, rectangular) frame having an opening in the optical axis (Z axis) direction and one side open. In an embodiment, the planar shape of the guide frame 500 may be approximately At least a portion of the reflective member 300 may be located on one side of the opening of the guide frame 500. Thus, the guide frame 500 and the reflective member 300 may be prevented from interfering with each other.

[0425] In another embodiment, the guide frame 500 may be a quadrilateral (eg, rectangular) frame with two sides open. In this case, the planar shape of the guide frame 500 may be approximately shape.

[0426] The camera module 5 may further include an image sensor module 800 and a housing 110 .

[0427] Reference Fig.10 and Fig.11 , the image sensor module 800 may include an image sensor 810 and a printed circuit board 830 connected to the image sensor 810 , and may further include a sensor housing 850 .

[0428] The image sensor 810 may convert light incident 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.

[0429] The electrical signal converted by the image sensor 810 may be output as an image through a display unit of a portable electronic device on which the camera module 5 is mounted.

[0430] 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.

[0431] The image sensor 810 may have an imaging surface on which light is received, and the imaging surface of the image sensor 810 may be a surface intersecting with the optical axis (Z axis) direction. The image sensor 810 may be disposed to be spaced apart from the reflective member 300. For example, the image sensor 810 may be spaced apart upward from the reflective member 300 in the optical axis (Z axis) direction.

[0432] In an embodiment, both the lens barrel 210 and the image sensor 810 may be disposed higher than the reflective member 300 in the optical axis (Z-axis) direction. For example, the lens barrel 210 and the image sensor 810 may be disposed closer to the object than the reflective member 300.

[0433] The image sensor module 800 may be mounted in the housing 100. As an example, the image sensor module 800 may be disposed in an opening 130 formed in one surface of the housing 100.

[0434] In an embodiment, the sensor housing 850 may be coupled to the printed circuit board 830, and the image sensor 810 may be disposed in an inner space of the sensor housing 850. In addition, either or both of the sensor housing 850 and the printed circuit board 830 may be coupled to the housing 100.

[0435] The lens barrel 210 of the lens module 200 and the image sensor 810 of the image sensor module 800 may be disposed in the opening 130 of the housing 100 and may be disposed to be spaced apart from each other in a direction intersecting the optical axis (Z axis) direction (eg, a first axis (X axis) direction).

[0436] The housing 110 may be coupled to the case 100 to cover an outer surface of the case 100 , and may play a role in protecting components inside the camera module 5 .

[0437] The reflective member 300 may have one surface facing the optical axis (Z axis) direction. One surface of the reflective member 300 may be a surface intersecting the optical axis (Z axis) direction. As an example, one surface of the reflective member 300 may be Fig.25 The upper surface of the reflective member 300 in FIG.

[0438] The lens barrel 210 and the image sensor 810 may be disposed closer to the object than the reflective member 300, and may be spaced apart from each other in a direction intersecting the optical axis (Z-axis) direction. That is, among the lens barrel 210, the image sensor 810, and the reflective member 300, the lens barrel 210 and the image sensor 810 may be those closest to the object, and the reflective member 300 may be the one farthest from the object.

[0439] In an implementation, the lens barrel 210 may face a portion of one surface (eg, upper surface) of the reflective member 300 , and the image sensor 810 may face another portion of the one surface (eg, upper surface) of the reflective member 300 .

[0440] The reflective member 300 may have one or more reflective surfaces. Since the light having passed through the lens module 200 enters the image sensor 810 after being reflected by the reflective member 300, a long optical path may be formed within a limited space.

[0441] Furthermore, since the lens barrel 210 is disposed in front of the reflective member 300 , the Fno (F number) of the camera module 5 can be reduced to capture a bright image.

[0442] Reference Fig.12 In an embodiment, the reflective member 300 may be in the form of a trapezoidal prism. The reflective member 300 may include an incident surface 310 into which light is incident, a first reflective surface 320 that reflects light that has passed through the incident surface 310, a second reflective surface 330 that reflects light reflected from the first reflective surface 320, a third reflective surface 340 that reflects light reflected from the second reflective surface 330, and an exit surface 350 that emits light reflected from the third reflective surface 340. The light that has passed through the exit surface 350 may be incident on the image sensor 810.

[0443] That the image sensor 810 is disposed closer to the object than the reflective member 300 may mean that the image sensor 810 is disposed closer to the object than the exit surface 350 of the reflective member 300 .

[0444] In an embodiment, the incident surface 310 , the second reflective surface 330 , and the exit surface 350 may be one surface extending on the same plane. For example, the incident surface 310 , the second reflective surface 330 , and the exit surface 350 may be parts of one surface of the reflective member 300 .

[0445] Each of the first reflective surface 320 and the third reflective surface 340 may be inclined with respect to the second reflective surface 330 .

[0446] A portion of the reflective member 300 may be disposed in the inner space of the carrier 400'. In an implementation, the incident surface 310 and the first reflective surface 320 of the reflective member 300 may be disposed in the inner space of the carrier 400'.

[0447] The camera module 5 may further include a focus adjustment unit 600 that moves the lens module 200 in the optical axis (Z axis) direction and an optical image stabilization unit 700 that moves the lens module 200 in a direction perpendicular to the optical axis (Z axis) direction.

[0448] The focus adjustment unit 600 may move the lens module 200 to focus on the object. For example, the focus adjustment unit 600 may move the lens module 200 by generating a driving force in the optical axis (Z-axis) direction.

[0449] The focus adjustment unit 600 may include a first magnet 610 and a first coil 630. The first magnet 610 and the first coil 630 may be disposed to face each other in a direction perpendicular to the optical axis (Z axis).

[0450] The first magnet 610 may be mounted on the lens module 200. As an example, the first magnet 610 may be mounted on one side surface of the bracket 230 of the lens module 200.

[0451] One surface of the first magnet 610 (e.g., the surface facing the first coil 630) may be magnetized to 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 first magnet 610 facing the first coil 630 along the optical axis (Z axis) direction.

[0452] The first coil 630 may be disposed to face the first magnet 610. For example, the first coil 630 may be disposed to face the first magnet 610 in a direction perpendicular to the optical axis (Z axis).

[0453] The first coil 630 may be provided on the connection substrate 1000, and a portion of the connection substrate 1000 on which the first coil 630 may be mounted is mounted on the carrier 400'. The first coil 630 may be provided on one surface of the connection substrate 1000. The connection substrate 1000 is mounted on a side surface of the carrier 400' in such a manner that the first magnet 610 and the first coil 630 face each other in a direction perpendicular to the optical axis (Z axis).

[0454] The carrier part 400 ′ may have a through hole penetrating the side surface of the carrier part 400 ′, and the first coil 630 disposed on the connection substrate 1000 may directly face the first magnet 610 through the through hole.

[0455] When adjusting the focus, the first magnet 610 may be a movable member that moves together with the lens module 200 in the optical axis (Z-axis) direction, and the first coil 630 may be a fixed member fixed to the connection substrate 1000 .

[0456] When power is applied to the first coil 630 , the lens module 200 may move in the optical axis (Z-axis) direction by an electromagnetic force generated between the first magnet 610 and the first coil 630 .

[0457] The first ball member B1 may be disposed between the lens module 200 and the carrier 400 ′. For example, the first ball member B1 may be disposed between the lens module 200 and the carrier 400 ′ to reduce friction when the lens module 200 moves.

[0458] The first ball member B1 may include a plurality of balls arranged along the optical axis (Z axis) direction. When the lens module 200 moves in the optical axis (Z axis) direction, the plurality of balls may move in a rolling manner in the optical axis (Z axis) direction.

[0459] The first ball member B1 may include a first ball group BG1 and a second ball group BG2, and each of the first ball group BG1 and the second ball group BG2 may include one or more balls. The first ball group BG1 and the second ball group BG2 may be disposed to be spaced apart from each other in a direction perpendicular to the optical axis (Z axis).

[0460] The first yoke 650 may be disposed on the carrier 400'. The first yoke 650 may be disposed at a position facing the first magnet 610. For example, the first coil 630 may be disposed on one surface of the connection substrate 1000, and the first yoke 650 may be disposed on another surface of the connection substrate 1000.

[0461] The first magnet 610 and the first yoke 650 may generate an attractive force therebetween. For example, the first yoke 650 may be made of a magnetic material. The attractive force may act between the first magnet 610 and the first yoke 650 in a direction perpendicular to the optical axis (Z axis).

[0462] Due to the attractive force generated between the first magnet 610 and the first yoke 650 , the first ball member B1 may come into contact with each of the lens module 200 and the carrier 400 ′.

[0463] The guide grooves may be formed in each of the surfaces facing each other of the lens module 200 and the carrier 400'. For example, a first guide groove g1 accommodating the first ball group BG1 and a second guide groove g2 accommodating the second ball group BG2 may be formed in each of the surfaces facing each other of the lens module 200 and the carrier 400'.

[0464] Each of the first guide groove g1 and the second guide groove g2 may extend in the optical axis (Z-axis) direction.

[0465] The first ball group BG1 and the second ball group BG2 may be arranged to be spaced apart from each other in the first axis (X axis) direction. The number of balls in the first ball group BG1 and the number of balls in the second ball group BG2 may be different. Specifically, the number of balls included in the first ball group BG1 may be greater than the number of balls included in the second ball group BG2.

[0466] For example, the first ball group BG1 may include two or more balls disposed along the optical axis (Z-axis) direction, and the second ball group BG2 may include a smaller number of balls than the number of balls included in the first ball group BG1.

[0467] Under the premise that the number of balls belonging to the first ball group BG1 and the number of balls belonging to the second ball group BG2 are different, the number of balls belonging to each ball group may be changed. Hereinafter, for convenience of explanation, description will be made based on an embodiment in which the first ball group BG1 includes four balls and the second ball group BG2 includes two balls.

[0468] Among the four balls included in the first ball group BG1, two outermost balls in the optical axis (Z-axis) direction may have the same diameter, and two balls disposed between the two outermost balls may have diameters smaller than those of the outermost balls.

[0469] The two balls included in the second ball group BG2 may have the same diameter.

[0470] Among the four balls included in the first ball group BG1 , each of the two outermost balls in the optical axis (Z-axis) direction may contact the carrier 400 ′ at two points and contact the lens module 200 at two points.

[0471] Each of the two balls in the second ball group BG2 may be in contact with the carrier 400 ′ at one point and with the lens module 200 at two points (or in contact with the carrier 400 ′ at two points and with the lens module 200 at one point).

[0472] The first ball group BG1 and the first guide groove g1 can be used as main guides to guide the movement of the lens module 200 in the optical axis (Z axis) direction, and the second ball group BG2 and the second guide groove g2 can be used as auxiliary guides to support the movement of the lens module 200 in the optical axis (Z axis) direction.

[0473] Either or both of the first ball group BG1 and the second ball group BG2 may be disposed to overlap the reflective member 300 in a direction perpendicular to the optical axis (Z axis) direction. For example, the first ball group BG1 may be disposed to overlap the reflective member 300 in the second axis (Y axis) direction.

[0474] In an embodiment, an auxiliary yoke (not shown) may be provided at a position facing the first magnet 610. For example, the auxiliary yoke may be provided on the connection substrate 1000 to face the first magnet 610. In addition, the auxiliary yoke may be provided on the inner side of the first coil 630.

[0475] The auxiliary yoke may be located closer to the first ball group BG1 than to the second ball group BG2 . The auxiliary yoke may be made of a material capable of generating an attractive force with the first magnet 610 .

[0476] Therefore, the center point of the resultant force of the attraction generated between the first magnet 610 and the first yoke 650 and the attraction generated between the first magnet 610 and the auxiliary yoke may be located closer to the first ball group BG1 than to the second ball group BG2.

[0477] In an embodiment, the camera module 5 may detect the position of the lens module 200 in the optical axis (Z-axis) direction.

[0478] To this end, a first position sensor 670 may be provided. The first position sensor 670 may be provided on the connection substrate 1000 to face the first magnet 610. The first position sensor 670 may be a Hall sensor.

[0479] The camera module 5 can stabilize the optical image by moving the carrier 400' in a direction perpendicular to the optical axis (Z axis) when capturing an image. To this end, the camera module 5 can include an optical image stabilization unit 700 that moves the carrier 400' in a direction perpendicular to the optical axis (Z axis).

[0480] The guide frame 500 and the bearing portion 400' may be sequentially received in the housing 100. For example, the guide frame 500 may be disposed between the bearing portion 400' and the housing 100.

[0481] The guide frame 500 and the carrying portion 400' can be moved together in one direction perpendicular to the optical axis (Z axis) by a driving force generated by the optical image stabilization unit 700, and the carrying portion 400' can be moved relative to the guide frame 500 in another direction perpendicular to the optical axis (Z axis) by another driving force generated by the optical image stabilization unit 700.

[0482] For example, the guide frame 500 and the carrier 400 ′ may move together in a first axis (X axis) perpendicular to the optical axis (Z axis), and the carrier 400 ′ may move relative to the guide frame 500 in a second axis (Y axis).

[0483] Since the lens module 200 is disposed inside the carrier 400 ′, the lens module 200 may move together with the carrier 400 ′.

[0484] For example, the carrier 400 ′ and the lens module 200 may move together in a first axis (X axis) direction and a second axis (Y axis) direction.

[0485] The optical image stabilization unit 700 may include a first sub-stabilization unit 710 and a second sub-stabilization unit 730. The first sub-stabilization unit 710 may generate a driving force in a first axis (X axis) direction, and the second sub-stabilization unit 730 may generate a driving force in a second axis (Y axis) direction.

[0486] The first sub-stabilizing unit 710 may include a second magnet 711 and a second coil 713. The second magnet 711 and the second coil 713 may be disposed to face each other in the first axis (X axis) direction.

[0487] The second magnet 711 may be disposed on the carrier 400'. For example, the second magnet 711 may be installed on one side surface of the carrier 400'.

[0488] One surface of the second magnet 711 may be magnetized to have an N pole or an S pole. The second magnet 711 may have a length extending in the second axis (Y axis) direction.

[0489] The other surface of the second magnet 711 may be magnetized to have a polarity opposite to that of one surface of the second magnet 711 .

[0490] The second coil 713 may be disposed to face the second magnet 711. For example, the second coil 713 may be disposed to face the second magnet 711 in the first axis (X axis) direction.

[0491] The second coil 713 may include one coil, and may have a ring shape with a hole.

[0492] In stabilizing the optical image, the second magnet 711 may be a movable member mounted on the carrier 400 ′, and the second coil 713 may be a fixed member fixed to the housing 100 .

[0493] When power is applied to the second coil 713 , the carrier 400 ′ and the guide frame 500 may move in the first axis (X axis) direction by an electromagnetic force generated between the second magnet 711 and the second coil 713 .

[0494] The second magnet 711 and the second coil 713 may generate a driving force in a direction in which they face each other (eg, a first axis (X-axis) direction).

[0495] The second sub-stabilizing unit 730 may include a third magnet 731 and a third coil 733. The third magnet 731 and the third coil 733 may be disposed to face each other in the second axis (Y axis) direction.

[0496] The third magnet 731 may be disposed on the carrier 400'. For example, the third magnet 731 may be installed on the other side surface of the carrier 400'.

[0497] One side surface and the other side surface of the carrier portion 400 ′ may be perpendicular to each other on a plane perpendicular to the optical axis (Z axis).

[0498] One surface of the third magnet 731 may be magnetized to have an N pole or an S pole. The third magnet 731 may have a length extending in the first axis (X axis) direction.

[0499] The other surface of the third magnet 731 may be magnetized to have a polarity opposite to that of one surface of the third magnet 731 .

[0500] The third coil 733 may be disposed to face the third magnet 731. For example, the third coil 733 may be disposed to face the third magnet 731 in the second axis (Y axis) direction.

[0501] The third coil 733 may include one coil, and may have a ring shape with a hole.

[0502] The second coil 713 and the third coil 733 may be disposed on the substrate 900. As an example, the second coil 713 and the third coil 733 may be disposed on the substrate 900 to face the second magnet 711 and the third magnet 731, respectively.

[0503] The substrate 900 is mounted on a side surface of the housing 100 , and the second coil 713 and the third coil 733 may directly face the second magnet 711 and the third magnet 731 through a through hole provided in the housing 100 .

[0504] In stabilizing the optical image, the third magnet 731 may be a movable member mounted on the carrier 400 ′, and the third coil 733 may be a fixed member fixed to the housing 100 .

[0505] When power is applied to the third coil 733 , the carrier 400 ′ may move in the second axis (Y axis) direction by an electromagnetic force generated between the third magnet 731 and the third coil 733 .

[0506] The third magnet 731 and the third coil 733 may generate a driving force in a direction in which they face each other (eg, a second axis (Y-axis) direction).

[0507] The second magnet 711 and the third magnet 731 may be disposed perpendicularly to each other on a plane perpendicular to the optical axis (Z axis), and the second coil 713 and the third coil 733 may also be disposed perpendicularly to each other on a plane perpendicular to the optical axis (Z axis).

[0508] The camera module 5 may include a plurality of ball members supporting the guide frame 500 and the carrier 400'. The plurality of ball members may be used to guide the movement of the guide frame 500 and the carrier 400' during the optical image stabilization process. The plurality of ball members may also be used to maintain a gap between the housing 100, the guide frame 500, and the carrier 400'.

[0509] The plurality of ball members may include a second ball member B2 and a third ball member B3.

[0510] The second ball member B2 may guide the movement of the guide frame 500 and the bearing portion 400 ′ in the first axis (X axis) direction, and the third ball member B3 may guide the movement of the bearing portion 400 ′ in the second axis (Y axis) direction.

[0511] As an example, when a driving force is generated in the first axis (X axis) direction, the second ball member B2 may move in a rolling manner in the first axis (X axis) direction. Therefore, the second ball member B2 may guide the movement of the guide frame 500 and the bearing portion 400' in the first axis (X axis) direction.

[0512] When a driving force is generated in the second axis (Y axis) direction, the third ball member B3 may move in a rolling manner in the second axis (Y axis) direction. Therefore, the third ball member B3 may guide the movement of the bearing portion 400' in the second axis (Y axis) direction.

[0513] The second ball member B2 may include a plurality of balls disposed between the housing 100 and the guide frame 500 , and the third ball member B3 may include a plurality of balls disposed between the guide frame 500 and the bearing portion 400 ′.

[0514] For example, each of the second ball member B2 and the third ball member B3 may include four balls.

[0515] The third guide groove g3 accommodating the second ball member B2 may be formed in either or both of surfaces facing each other in the optical axis (Z axis) direction of the housing 100 and the guide frame 500. The third guide groove g3 may include a plurality of grooves corresponding to the plurality of balls of the second ball member B2.

[0516] The second ball member B2 may be received in the third guide groove g3 and inserted between the housing 100 and the guide frame 500 .

[0517] When the second ball member B2 is accommodated in the third guide groove g3, the second ball member B2 can move only in the first axis (X axis) direction, while its movement in the optical axis (Z axis) direction and the second axis (Y axis) direction is restricted. As an example, the second ball member B2 can move only in a rolling manner in the first axis (X axis) direction.

[0518] To this end, a planar shape of each of the plurality of grooves of the third guide grooves g3 may be a rectangle having a length extending in the first axis (X axis) direction.

[0519] The fourth guide groove g4 accommodating the third ball member B3 may be formed in either or both surfaces of the guide frame 500 and the bearing portion 400' facing each other in the optical axis (Z axis) direction. The fourth guide groove g4 may include a plurality of grooves corresponding to the plurality of balls of the third ball member B3.

[0520] The third ball member B3 may be received in the fourth guide groove g4 and inserted between the guide frame 500 and the bearing portion 400 ′.

[0521] When the third ball member B3 is accommodated in the fourth guide groove g4, the third ball member B3 can move only in the second axis (Y axis) direction, while its movement in the optical axis (Z axis) direction and the first axis (X axis) direction is restricted. As an example, the third ball member B3 can move only in the second axis (Y axis) direction in a rolling manner.

[0522] To this end, a planar shape of each of the plurality of grooves of the fourth guide groove g4 may be a rectangle having a length extending in the second axis (Y axis) direction.

[0523] When a driving force is generated in the first axis (X axis), the guide frame 500 and the carrier 400' may move together in the first axis (X axis). In addition, the lens module 200 may also move together with the carrier 400' in the first axis (X axis).

[0524] Here, the second ball member B2 can move in a rolling manner along the first axis (X axis) direction. At this time, the movement of the third ball member B3 can be restricted.

[0525] When a driving force is generated in the second axis (Y axis), the carrier 400' may move in the second axis (Y axis) relative to the guide frame 500. In addition, the lens module 200 may also move in the second axis (Y axis) together with the carrier 400'.

[0526] Here, the third ball member B3 can move in a rolling manner along the second axis (Y axis) direction. At this time, the movement of the second ball member B2 can be restricted.

[0527] In an embodiment, the camera module 5 may detect the position of the lens module 200 in a direction perpendicular to the optical axis (Z axis).

[0528] To this end, a second position sensor (not shown) and a third position sensor (not shown) may be provided. The second position sensor may be provided on the substrate 900 to face the second magnet 711, and the third position sensor may be provided on the substrate 900 to face the third magnet 731. The second position sensor and the third position sensor may be Hall sensors.

[0529] In the present disclosure, second and third yokes (not shown) may be provided to keep the housing 100 and the guide frame 500 in contact with the second ball member B2 and to keep the guide frame 500 and the bearing portion 400 ′ in contact with the third ball member B3 .

[0530] The second yoke and the third yoke may be fixed to the housing 100 , and may be disposed to face the second magnet 711 and the third magnet 731 , respectively, in the optical axis (Z-axis) direction.

[0531] Therefore, an attractive force can be generated between the second yoke and the second magnet 711 and between the third yoke and the third magnet 731 in the optical axis (Z-axis) direction.

[0532] Due to the attraction generated between the second yoke and the second magnet 711 and between the third yoke and the third magnet 731, the bearing part 400' and the guide frame 500 can be pressed in the direction toward the second yoke and the third yoke, so that the bearing part 400' and the guide frame 500 can be kept in contact with the second ball member B2 and the third ball member B3.

[0533] The second and third yokes may be made of a material capable of generating an attractive force with the second and third magnets 711 and 731. As an example, the second and third yokes may be made of a magnetic material.

[0534] The stopper 410 may be coupled to the carrier 400 ′. The stopper 410 may be coupled to the carrier 400 ′ to cover at least a portion of an upper surface of the lens module 200 .

[0535] The stopper 410 may prevent the lens module 200 from being separated from the carrier 400 ′ due to external impact or other interference.

[0536] A buffer member (not shown) having an elastic property may be coupled to an edge portion of the stopper 410 .

[0537] The first coil 630 of the focus adjustment unit 600 may be disposed on the connection substrate 1000 .

[0538] Since the connection substrate 1000 is mounted on the carrier 400', the connection substrate 1000 may move together with the carrier 400' when stabilizing the optical image. That is, since the connection substrate 1000 moves when stabilizing the optical image, a configuration for stably supplying power to the first coil 630 is required.

[0539] Reference Fig.26 , the connection substrate 1000 may include a mounting portion 1010 , a first extending portion 1020 , and a second extending portion 1030 . The first coil 630 may be disposed on the mounting portion 1010 .

[0540] The first extension portion 1020 may extend after being bent from one side of the mounting portion 1010. The first extension portion 1020 may be disposed to be spaced apart from the side surface of the carrier 400' and may extend along the side surface of the carrier 400'. The first extension portion 1020 may be bent at least once and may be made of a flexible material.

[0541] The second extension portion 1030 may extend after being bent from one side of the first extension portion 1020. In addition, the second extension portion 1030 may be connected to the printed circuit board 830 to supply power to the connection substrate 1000.

[0542] A portion of the second extending portion 1030 may be located inside the housing 100 , and another portion of the second extending portion 1030 may be located outside the housing 100 .

[0543] A through hole 140 passing through the side surface of the case 100 may be provided in the side surface of the case 100. Another portion of the second extension portion 1030 may extend to the outside of the case 100 through the through hole 140 of the case 100.

[0544] When the carrying portion 400 ′ moves, at least a portion of the connection substrate 1000 may be bent.

[0545] Therefore, even if the carrier 400 ′ moves when stabilizing the optical image, the connection substrate 1000 can stably supply power to the first coil 630 .

[0546] Fig. 27 is a perspective view of a camera module according to another embodiment of the present disclosure, and Fig.28 yes Fig. 27 An exploded perspective view of the camera module.

[0547] Reference Fig. 27 and Fig.28 , a camera module 6 according to another embodiment of the present disclosure may include a lens module 200 , a reflective member 300 , and a housing 100 .

[0548] The lens module 200 may include a lens barrel 210 and a bracket 230. The lens barrel 210 may have a hollow cylindrical shape, and at least one lens for imaging an object may be accommodated inside the lens barrel 210. In the case where a plurality of lenses are arranged, the plurality of lenses may be installed inside the lens barrel 210 along the optical axis (Z axis).

[0549] The lens barrel 210 may be coupled to the bracket 230. The lens barrel 210 and the bracket 230 may move together.

[0550] The housing 100 may have an internal space. In an embodiment, the housing 100 may be shaped like a quadrilateral (e.g., rectangular) box. An opening 130 may be formed in one surface of the housing 100. The internal space of the housing 100 may be exposed to the outside of the housing 100 through the opening 130. One surface of the housing 100 may be as shown in FIG. Fig.28 The upper surface of the housing 100 is shown in FIG.

[0551] The reflective member 300 may be disposed in the inner space of the housing 100. In addition, the lens module 200 may be disposed in front of the reflective member 300. Here, the expression "in front of" may refer to a positive optical axis (Z axis) direction (+Z axis direction) relative to the reflective member 300. For example, the lens module 200 may be spaced apart upward from the reflective member 300 in the optical axis (Z axis) direction.

[0552] Therefore, light may be incident on the reflective member 300 after passing through the lens module 200 .

[0553] The lens module 200 may be moved in one or more of three axial directions intersecting each other. In addition, the lens module 200 may be moved relative to the reflective member 300.

[0554] For example, the lens module 200 may be moved in the direction of the optical axis (Z axis) for focus adjustment. In addition, the lens module 200 may be moved in a direction perpendicular to the optical axis (Z axis) for optical image stabilization.

[0555] In an embodiment, the three axial directions intersecting each other may be an optical axis (Z-axis) direction, a first axis (X-axis) direction, and a second axis (Y-axis) direction.

[0556] The camera module 6 may further include a carrying portion 400 and a guide frame 500 .

[0557] The carrier 400 may be disposed inside the housing 100 , and may be movable relative to the housing 100 in the optical axis (Z-axis) direction.

[0558] The lens module 200 may be disposed on the carrier 400, and the carrier 400 and the lens module 200 may move together in the optical axis (Z axis) direction. Therefore, the camera module 6 may adjust the focus.

[0559] In addition, the lens module 200 may move in a direction perpendicular to the optical axis (Z-axis) direction to stabilize an optical image when capturing an image.

[0560] The guide frame 500 may be disposed between the carrier 400 and the lens module 200. The guide frame 500 may be used to guide the lens module 200 to be movable in a direction perpendicular to the optical axis (Z-axis) direction.

[0561] The guide frame 500 may be a quadrilateral (eg, rectangular) frame having an opening in the optical axis (Z-axis) direction. In an embodiment, the planar shape of the guide frame 500 may be approximately shape.

[0562] The bearing portion 400 and the guide frame 500 may be disposed in front of the reflective member 300. That is, the bearing portion 400 and the guide frame 500 may be disposed to be higher than the reflective member 300 in the optical axis (Z-axis) direction.

[0563] The lens module 200 may be accommodated in the housing 100. For example, the lens module 200 may be disposed inside the opening 130 formed in one surface of the housing 100. In an embodiment, the carrier 400 may be disposed inside the housing 100, and the lens module 200 may be accommodated inside the carrier 400.

[0564] The camera module 6 can adjust the focus by moving the lens module 200 in the optical axis (Z axis) direction, and can stabilize the optical image by moving the lens module 200 in a direction perpendicular to the optical axis (Z axis) when capturing an image.

[0565] The camera module 6 may further include a focus adjustment unit 600 that moves the lens module 200 in the optical axis (Z axis) direction and an optical image stabilization unit 700 that moves the lens module 200 in a direction perpendicular to the optical axis (Z axis) direction.

[0566] The camera module 6 may further include an image sensor module 800 and a housing 110 .

[0567] Reference Fig.10 and Fig.11 , the image sensor module 800 may include an image sensor 810 and a printed circuit board 830 connected to the image sensor 810 , and may further include a sensor housing 850 .

[0568] The image sensor 810 may convert light incident 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.

[0569] The electrical signal converted by the image sensor 810 may be output as an image through a display unit of a portable electronic device on which the camera module 6 is mounted.

[0570] 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.

[0571] The image sensor 810 may have an imaging surface on which light is received, and the imaging surface of the image sensor 810 may be a surface intersecting with the optical axis (Z axis) direction. The image sensor 810 may be disposed to be spaced apart from the reflective member 300. For example, the image sensor 810 may be spaced apart upward from the reflective member 300 in the optical axis (Z axis) direction.

[0572] In an embodiment, both the lens module 200 and the image sensor 810 may be disposed higher than the reflective member 300 in the optical axis (Z axis) direction. For example, the lens module 200 and the image sensor 810 may be disposed closer to the object than the reflective member 300.

[0573] The image sensor module 800 may be mounted in the housing 100. As an example, the image sensor module 800 may be disposed in an opening 130 formed in one surface of the housing 100.

[0574] In an embodiment, the sensor housing 850 may be coupled to the printed circuit board 830, and the image sensor 810 may be disposed in an inner space of the sensor housing 850. In addition, either or both of the sensor housing 850 and the printed circuit board 830 may be coupled to the housing 100.

[0575] The lens module 200 and the image sensor 810 may be disposed in the opening 130 of the housing 100 , and may be disposed to be spaced apart from each other in a direction intersecting the optical axis (Z axis) direction, for example, a first axis (X axis) direction.

[0576] The housing 110 may be coupled to the case 100 to cover an outer surface of the case 100 , and may play a role in protecting internal components of the camera module 6 .

[0577] The reflective member 300 may have one surface facing the optical axis (Z axis) direction. One surface of the reflective member 300 may be a surface intersecting the optical axis (Z axis) direction. As an example, one surface of the reflective member 300 may be Fig.28 The upper surface of the reflective member 300 in FIG.

[0578] The lens module 200 and the image sensor 810 may be disposed closer to the object than the reflective member 300, and may be spaced apart from each other in a direction intersecting the optical axis (Z-axis) direction. That is, among the lens module 200, the image sensor 810, and the reflective member 300, the lens module 200 and the image sensor 810 may be those closest to the object, and the reflective member 300 may be the one farthest from the object.

[0579] In an implementation, the lens module 200 may face a portion of one surface (eg, upper surface) of the reflective member 300 , and the image sensor 810 may face another portion of the one surface (eg, upper surface) of the reflective member 300 .

[0580] The reflective member 300 may have one or more reflective surfaces. Since the light having passed through the lens module 200 enters the image sensor 810 after being reflected by the reflective member 300, a long optical path may be formed within a limited space.

[0581] In addition, since the lens module 200 is disposed in front of the reflective member 300, the Fno (F number) of the camera module 6 may be reduced to capture a bright image.

[0582] Reference Fig.12 In an embodiment, the reflective member 300 may be in the form of a trapezoidal prism. The reflective member 300 may include an incident surface 310 into which light is incident, a first reflective surface 320 that reflects light that has passed through the incident surface 310, a second reflective surface 330 that reflects light reflected from the first reflective surface 320, a third reflective surface 340 that reflects light reflected from the second reflective surface 330, and an exit surface 350 that emits light reflected from the third reflective surface 340. The light that has passed through the exit surface 350 may be incident on the image sensor 810.

[0583] That the image sensor 810 is disposed closer to the object than the reflective member 300 may mean that the image sensor 810 is disposed closer to the object than the exit surface 350 of the reflective member 300 .

[0584] The incident surface 310, the second reflective surface 330, and the exit surface 350 may be one surface extending on the same plane.

[0585] Each of the first reflective surface 320 and the third reflective surface 340 may be inclined with respect to the second reflective surface 330 .

[0586] A portion of the reflective member 300 may be disposed below the carrier 400. In an implementation, the incident surface 310 and the first reflective surface 320 of the reflective member 300 may be disposed below the carrier 400.

[0587] Reference Fig.28 , at least a portion of the bottom surface of the housing 100 facing the image sensor 810 in the optical axis (Z axis) direction may be tilted relative to the optical axis (Z axis) direction. That is, at least a portion of the bottom surface of the housing 100 may be an inclined surface. For example, a portion of the bottom surface of the housing 100 may include a first inclined surface 121. In an embodiment, the first inclined surface 121 of the bottom surface of the housing 100 may face the third reflective surface 340 of the reflective member 300.

[0588] In addition, another part of the bottom surface of the housing 100 may also be an inclined surface. For example, another part of the bottom surface of the housing 100 may include a second inclined surface 122. The first inclined surface 121 and the second inclined surface 122 of the bottom surface of the housing 100 may be arranged to be spaced apart from each other in the first axis (X axis) direction. When the first inclined surface 121 and the second inclined surface 122 are inclined downward, the first inclined surface 121 and the second inclined surface 122 may be inclined in the optical axis (Z axis) direction to approach each other.

[0589] In an implementation, the second inclined surface 122 of the bottom surface of the housing 100 may face the first reflective surface 320 of the reflective member 300 .

[0590] At least a portion of the third reflective surface 340 may be located between the first inclined surface 121 of the housing 100 and the image sensor 810. The third reflective surface 340 and the first inclined surface 121 of the housing 100 may be parallel to each other. For example, the inclination angle of the third reflective surface 340 relative to the optical axis (Z axis) direction and the inclination angle of the first inclined surface 121 of the housing 100 relative to the optical axis (Z axis) direction may be the same.

[0591] At least a portion of the first reflective surface 320 may be located between the second inclined surface 122 of the housing 100 and the lens module 200. The first reflective surface 320 and the second inclined surface 122 of the housing 100 may be parallel to each other. For example, the inclination angle of the first reflective surface 320 relative to the optical axis (Z axis) direction and the inclination angle of the second inclined surface 122 of the housing 100 relative to the optical axis (Z axis) direction may be the same.

[0592] The camera module 6 may move the lens module 200 to focus on the object. To this end, the camera module 6 may include a focus adjustment unit 600.

[0593] The focus adjustment unit 600 can move the carrier 400 by generating a driving force in the optical axis (Z axis) direction. Since the lens module 200 is disposed on the carrier 400, the carrier 400 and the lens module 200 can be moved together in the optical axis (Z axis) direction by the driving force generated by the focus adjustment unit 600. In addition, since the guide frame 500 is disposed on the carrier 400, the guide frame 500 can be moved together with the carrier 400 in the optical axis (Z axis) direction by the driving force generated by the focus adjustment unit 600.

[0594] The focus adjustment unit 600 may include a first magnet 610 and a first coil 630. The first magnet 610 and the first coil 630 may be disposed to face each other in a direction perpendicular to the optical axis (Z axis).

[0595] The focus adjustment unit 600 may be disposed upwardly spaced apart from the reflective member 300 in the optical axis (Z axis) direction. That is, the focus adjustment unit 600 may be disposed higher than the reflective member 300 in the optical axis (Z axis) direction.

[0596] The first magnet 610 may be mounted on the carrier 400. As an example, the first magnet 610 may be mounted on one side surface of the carrier 400. A back yoke may be provided between one side surface of the carrier 400 and the first magnet 610. The back yoke may be made of a magnetic material. The back yoke makes it possible to prevent the magnetic field of the first magnet 610 from leaking into the carrier 400.

[0597] One surface of the first magnet 610 (e.g., the surface facing the first coil 630) may be magnetized to 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 first magnet 610 facing the first coil 630 along the optical axis (Z axis) direction.

[0598] The first coil 630 may be disposed to face the first magnet 610. For example, the first coil 630 may be disposed to face the first magnet 610 in a direction perpendicular to the optical axis (Z axis).

[0599] The first coil 630 may be provided on the substrate 900, and the substrate 900 may be mounted on the housing 100 in such a manner that the first magnet 610 and the first coil 630 face each other in a direction perpendicular to the optical axis (Z axis). As an example, the first coil 630 may be provided on one surface of the substrate 900. The substrate 900 may be mounted on a side surface of the housing 100 in such a manner that the first magnet 610 and the first coil 630 face each other in a direction perpendicular to the optical axis (Z axis).

[0600] The housing 100 may have a through hole penetrating the housing 100 , and the first coil 630 disposed on the substrate 900 may directly face the first magnet 610 through the through hole.

[0601] When adjusting the focus, the first magnet 610 may be a movable member mounted on the carrier 400 and moving in the optical axis (Z axis) direction together with the carrier 400 , and the first coil 630 may be a fixed member fixed to the substrate 900 .

[0602] When power is applied to the first coil 630 , the carrier 400 may move in the optical axis (Z-axis) direction by an electromagnetic force generated between the first magnet 610 and the first coil 630 .

[0603] Since the lens module 200 is disposed on the carrying portion 400 , the lens module 200 can also move in the optical axis (Z-axis) direction through the movement of the carrying portion 400 .

[0604] The first ball member B1 may be disposed between the bearing portion 400 and the housing 100. For example, the first ball member B1 may be disposed between the bearing portion 400 and the housing 100 to reduce friction when the bearing portion 400 moves.

[0605] The first ball member B1 may include a plurality of balls arranged along the optical axis (Z axis) direction. When the bearing portion 400 moves in the optical axis (Z axis) direction, the plurality of balls may move in a rolling manner in the optical axis (Z axis) direction.

[0606] The first ball member B1 may include a first ball group BG1 and a second ball group BG2, and each of the first ball group BG1 and the second ball group BG2 may include one or more balls. The first ball group BG1 and the second ball group BG2 may be disposed to be spaced apart from each other in a direction perpendicular to the optical axis (Z axis).

[0607] A first yoke (not shown) may be provided on the housing 100. The first yoke may be provided at a position facing the first magnet 610. For example, the first coil 630 may be provided on one surface of the substrate 900, and the first yoke may be provided on another surface of the substrate 900.

[0608] The first magnet 610 and the first yoke may generate an attractive force therebetween. For example, the first yoke may be made of a magnetic material. The attractive force may act between the first magnet 610 and the first yoke in a direction perpendicular to the optical axis (Z axis).

[0609] Due to the attractive force generated between the first magnet 610 and the first yoke, the first ball member B1 may come into contact with each of the bearing portion 400 and the housing 100 .

[0610] The guide grooves may be formed in each of the facing surfaces of the carrier 400 and the housing 100. For example, a first guide groove g1 accommodating the first ball group BG1 and a second guide groove g2 accommodating the second ball group BG2 may be formed in each of the facing surfaces of the carrier 400 and the housing 100.

[0611] Each of the first guide groove g1 and the second guide groove g2 may extend in the optical axis (Z-axis) direction.

[0612] The first ball group BG1 and the second ball group BG2 may be arranged to be spaced apart from each other in the first axis (X axis) direction. The number of balls in the first ball group BG1 and the number of balls in the second ball group BG2 may be different. Specifically, the number of balls included in the first ball group BG1 may be greater than the number of balls included in the second ball group BG2.

[0613] For example, the first ball group BG1 may include two or more balls disposed along the optical axis (Z-axis) direction, and the second ball group BG2 may include a smaller number of balls than the number of balls included in the first ball group BG1.

[0614] Under the premise that the number of balls belonging to the first ball group BG1 and the number of balls belonging to the second ball group BG2 are different, the number of balls belonging to each ball group may be changed. Hereinafter, for convenience of explanation, description will be made based on an embodiment in which the first ball group BG1 includes two balls and the second ball group BG2 includes one ball.

[0615] Each of the two balls in the first ball group BG1 may be in contact with the bearing portion 400 at two points and in contact with the housing 100 at two points.

[0616] One ball in the second ball group BG2 may be in contact with the bearing portion 400 at one point and in contact with the housing 100 at two points (or in contact with the bearing portion 400 at two points and in contact with the housing 100 at one point).

[0617] The first ball group BG1 and the first guide groove g1 can be used as main guides to guide the movement of the bearing part 400 in the optical axis (Z axis) direction, and the second ball group BG2 and the second guide groove g2 can be used as auxiliary guides to support the movement of the bearing part 400 in the optical axis (Z axis) direction.

[0618] The first ball group BG1 and the second ball group BG2 may be disposed higher than the reflective member 300 in the optical axis (Z-axis) direction.

[0619] In an embodiment, an auxiliary yoke (not shown) may be provided at a position facing the first magnet 610. For example, the auxiliary yoke may be provided on the substrate 900 to face the first magnet 610. In addition, the auxiliary yoke may be provided on the inner side of the first coil 630.

[0620] The auxiliary yoke may be located closer to the first ball group BG1 than to the second ball group BG2 . The auxiliary yoke may be made of a material capable of generating an attractive force with the first magnet 610 .

[0621] Therefore, the center point of the resultant force of the attraction generated between the first magnet 610 and the first yoke and the attraction generated between the first magnet 610 and the auxiliary yoke may be located closer to the first ball group BG1 than to the second ball group BG2.

[0622] In an embodiment, the camera module 6 may detect the position of the carrier 400 in the optical axis (Z-axis) direction.

[0623] To this end, a first position sensor (not shown) may be provided. The first position sensor may be provided on the substrate 900 to face the first magnet 610. The first position sensor may be a Hall sensor.

[0624] The camera module 6 can stabilize the optical image by moving the lens module 200 in a direction perpendicular to the optical axis (Z axis) when capturing an image. To this end, the camera module 6 can include an optical image stabilization unit 700 that moves the lens module 200 in a direction perpendicular to the optical axis (Z axis).

[0625] The guide frame 500 and the lens module 200 may be sequentially received in the carrier 400. For example, the guide frame 500 may be disposed between the carrier 400 and the lens module 200.

[0626] The guide frame 500 and the lens module 200 can be moved together in one direction perpendicular to the optical axis (Z axis) by a driving force generated by the optical image stabilization unit 700, and the lens module 200 can be moved relative to the guide frame 500 in another direction perpendicular to the optical axis (Z axis) by another driving force generated by the optical image stabilization unit 700.

[0627] For example, the guide frame 500 and the lens module 200 can move together in a first axis (X axis) direction perpendicular to the optical axis (Z axis), and the lens module 200 can move relative to the guide frame 500 in a second axis (Y axis) direction perpendicular to both the optical axis (Z axis) and the first axis (X axis).

[0628] The optical image stabilization unit 700 may include a first sub-stabilization unit 710 and a second sub-stabilization unit 730. The first sub-stabilization unit 710 may generate a driving force in a first axis (X axis) direction, and the second sub-stabilization unit 730 may generate a driving force in a second axis (Y axis) direction. The first sub-stabilization unit 710 and the second sub-stabilization unit 730 may be disposed to be spaced apart upward from the reflective member 300 in the optical axis (Z axis) direction. That is, the optical image stabilization unit 700 may be disposed to be higher than the reflective member 300 in the optical axis (Z axis) direction.

[0629] The first sub-stabilizing unit 710 may include a second magnet 711 and a second coil 713. The second magnet 711 and the second coil 713 may be disposed to face each other in the first axis (X axis) direction.

[0630] The second magnet 711 may be disposed on the lens module 200. For example, the second magnet 711 may be mounted on one side surface of the bracket 230.

[0631] One surface of the second magnet 711 (eg, a surface facing the second coil 713) may be magnetized to have an N pole or an S pole. The second magnet 711 may have a length extending in the second axis (Y axis) direction.

[0632] The other surface of the second magnet 711 may be magnetized to have a polarity opposite to that of one surface of the second magnet 711 .

[0633] The second coil 713 may be disposed to face the second magnet 711. For example, the second coil 713 may be disposed to face the second magnet 711 in the first axis (X axis) direction.

[0634] The second coil 713 may be disposed on the substrate 900 , and the substrate 900 may be mounted on the housing 100 in such a manner that the second magnet 711 and the second coil 713 face each other in the first axis (X axis) direction.

[0635] The housing 100 may have a through hole, and the second coil 713 disposed on the substrate 900 may directly face the second magnet 711 through the through hole.

[0636] In stabilizing the optical image, the second magnet 711 may be a movable member mounted on the lens module 200 , and the second coil 713 may be a fixed member fixed to the housing 100 .

[0637] When power is applied to the second coil 713 , the lens module 200 and the guide frame 500 may move in the first axis (X axis) direction by an electromagnetic force generated between the second magnet 711 and the second coil 713 .

[0638] The second magnet 711 and the second coil 713 may generate a driving force in a direction in which they face each other (eg, a first axis (X-axis) direction).

[0639] The second sub-stabilizing unit 730 may include a third magnet 731 and a third coil 733. The third magnet 731 and the third coil 733 may be disposed to face each other in the second axis (Y axis) direction.

[0640] The third magnet 731 may be disposed on the lens module 200. For example, the third magnet 731 may be installed on the other side surface of the bracket 230.

[0641] One surface of the third magnet 731 (eg, a surface facing the third coil 733 ) may be magnetized to have an S pole or an N pole. The third magnet 731 may have a length extending in the first axis (X axis) direction.

[0642] The other surface of the third magnet 731 may be magnetized to have a polarity opposite to that of one surface of the third magnet 731 .

[0643] The third coil 733 may be disposed to face the third magnet 731. For example, the third coil 733 may be disposed to face the third magnet 731 in the second axis (Y axis) direction.

[0644] The third coil 733 may be disposed on the substrate 900 , and the substrate 900 may be mounted on the housing 100 in such a manner that the third magnet 731 and the third coil 733 face each other in the second axis (Y-axis) direction.

[0645] The housing 100 may have a through hole, and the third coil 733 disposed on the substrate 900 may directly face the third magnet 731 through the through hole.

[0646] In stabilizing the optical image, the third magnet 731 may be a movable member mounted on the lens module 200 , and the third coil 733 may be a fixed member fixed to the housing 100 .

[0647] When power is applied to the third coil 733 , the lens module 200 may move in the second axis (Y-axis) direction by an electromagnetic force generated between the third magnet 731 and the third coil 733 .

[0648] The third magnet 731 and the third coil 733 may generate a driving force in a direction in which they face each other (eg, a second axis (Y-axis) direction).

[0649] The second magnet 711 and the third magnet 731 may be disposed perpendicularly to each other on a plane perpendicular to the optical axis (Z axis), and the second coil 713 and the third coil 733 may also be disposed perpendicularly to each other on a plane perpendicular to the optical axis (Z axis).

[0650] The first magnet 610 of the focus adjustment unit 600 and the third magnet 731 of the optical image stabilization unit 700 may be disposed to be spaced apart from each other in the second axis (Y-axis) direction.

[0651] The camera module 6 according to another embodiment of the present disclosure may include a plurality of ball members supporting the guide frame 500 and the lens module 200. The plurality of ball members may be used to guide the movement of the guide frame 500 and the lens module 200 during the optical image stabilization process. The plurality of ball members may also be used to maintain a gap between the bearing portion 400, the guide frame 500, and the lens module 200.

[0652] The plurality of ball members may include a second ball member B2 and a third ball member B3. Since the second ball member B2 and the third ball member B3 are similar to those in the other embodiments described above, a detailed description thereof will be omitted.

[0653] When a driving force is generated in the first axis (X axis) direction, the guide frame 500 and the lens module 200 can move together in the first axis (X axis) direction. Here, the second ball member B2 can move in a rolling manner along the first axis (X axis) direction. At this time, the movement of the third ball member B3 can be restricted.

[0654] When a driving force is generated in the second axis (Y axis) direction, the lens module 200 can move in the second axis (Y axis) direction relative to the guide frame 500. Here, the third ball member B3 can move in a rolling manner along the second axis (Y axis) direction. At this time, the movement of the second ball member B2 can be restricted.

[0655] In an embodiment, the camera module 6 may detect the position of the lens module 200 in a direction perpendicular to the optical axis (Z axis).

[0656] To this end, a second position sensor (not shown) and a third position sensor (not shown) may be provided. The second position sensor may be provided on the substrate 900 to face the second magnet 711, and the third position sensor may be provided on the substrate 900 to face the third magnet 731. The second position sensor and the third position sensor may be Hall sensors.

[0657] In the present disclosure, a second yoke (not shown) and a third yoke (not shown) may be provided to keep the bearing portion 400 and the guide frame 500 in contact with the second ball member B2 and to keep the guide frame 500 and the lens module 200 in contact with the third ball member B3.

[0658] The second and third yokes may be fixed to the carrier 400 and disposed to face the second and third magnets 711 and 731 in the optical axis (Z axis) direction, respectively.

[0659] Therefore, an attractive force can be generated between the second yoke and the second magnet 711 and between the third yoke and the third magnet 731 in the optical axis (Z-axis) direction.

[0660] Due to the attraction generated between the second yoke and the second magnet 711 and the attraction generated between the third yoke and the third magnet 731, the lens module 200 and the guide frame 500 can be pressed in the direction toward the second yoke and the third yoke, so that the guide frame 500 and the lens module 200 can be kept in contact with the second ball member B2 and the third ball member B3.

[0661] The second and third yokes may be made of a material capable of generating an attractive force with the second and third magnets 711 and 731. As an example, the second and third yokes may be made of a magnetic material.

[0663] The stopper 430 may prevent the guide frame 500 and the lens module 200 from being separated from the carrier 400 due to external impact or other interference.

[0664] A buffer member (not shown) having an elastic property may be coupled to an edge portion of the stopper 430 .

[0665] As described above, according to the embodiments of the present disclosure, the size of the camera module can be reduced.
