[0110] Hereinafter, embodiments of the present invention that can specifically achieve the above purpose will be described with reference to the attached drawings.

[0111] In the description of the embodiments, when it is described that each element is formed "on or under", "on or under" includes both cases where two elements are in direct contact with each other or where one or more other elements are formed by being disposed indirectly between the two elements. In addition, when it is expressed as "on or under", it can include the meaning of not only the upward direction but also the downward direction based on one element.

[0112] Additionally, relational terms such as “first” and “second,” “upper / upper / lower,” and “lower / lower / below” used hereinafter may be used only to distinguish one entity or element from another entity or element, without necessarily requiring or implying any physical or logical relationship or order between such entities or elements. In addition, the same reference numbers represent the same elements throughout the description of the drawings.

[0113] Furthermore, terms such as "include," "comprise," or "have" described above, unless specifically stated otherwise, imply that the corresponding component may be included, and thus should be interpreted to include other components rather than excluding other components. Furthermore, terms such as "corresponding" described above may include at least one of the meanings of "opposite" or "overlapping."

[0114] Hereinafter, a camera device according to an embodiment and an optical device including the same will be described with reference to the attached drawings. For convenience of explanation, the camera device according to the embodiment will be described using a Cartesian coordinate system (x, y, z), but it may be described using another coordinate system, and the embodiment is not limited thereto. In each drawing, the X-axis and the Y-axis may mean a direction perpendicular to the Z-axis, which is the optical axis (OA) direction.

[0115] In addition, the Z-axis direction, which is the optical axis (OA) direction, can be defined as one of the 'first to third directions', the X-axis direction can be defined as another of the 'first to third directions', and the Y-axis direction can be defined as the remaining one of the 'first to third directions'. In addition, the Y-axis can be defined as one of the "first axis and the second axis", and the X-axis can be defined as the remaining one of the "first axis and the second axis". In addition, the Y-axis direction can be defined as one of the "first-axis direction and the second-axis direction", and the X-axis direction can be defined as the remaining one of the "first-axis direction and the second-axis direction". For example, the optical axis direction can be the direction of the optical axis or a direction parallel to the optical axis.

[0116] Additionally, the term "terminal" below may be expressed as a pad, electrode, or conductive layer. Additionally, the term "code value" below may be expressed as data or a digital value.

[0117] In addition, in the embodiment, in the coupling between the protrusion and the hole for coupling two components to each other, one of the components may be a coupling protrusion (or coupling hole), and the other side may be a corresponding coupling hole (or coupling protrusion).

[0118] A camera device according to an embodiment may perform a shake correction function, an auto-focusing function, and a zoom function. The 'shake correction function' may be a function that moves a lens in a direction perpendicular to the optical axis direction or tilts the lens with respect to the optical axis to offset vibration (or movement) caused by the user's shaking hand. In addition, the 'auto-focusing function' may be a function that automatically focuses on a subject by moving the lens in the optical axis direction according to the distance of the subject to obtain a clear image of the subject on the image sensor. The 'zoom function' may be a zooming function that takes pictures by increasing or decreasing the magnification of a distant subject through a zoom lens.

[0119] Hereinafter, “camera device” may be replaced with “camera”, “camera module”, “camera camera” or “camera”.

[0120] FIG. 1 is a perspective view of a camera device (200) according to an embodiment, FIG. 2a is a first separated perspective view of the camera device (200) of FIG. 1, FIG. 2b is a second separated perspective view of the camera device (200) of FIG. 1, FIG. 3a is an AB cross-sectional view of the camera device (200) of FIG. 1, FIG. 3b is a CD cross-sectional view of the camera device (200) of FIG. 1, FIG. 4a is a first separated perspective view of the first actuator (310) of FIG. 2a, FIG. 4b is a first separated perspective view of the first actuator (310) of FIG. 2a, FIG. 5a is a first perspective view of the first housing (610), FIG. 5b is a second perspective view of the first housing (610), FIG. 6a is a first perspective view of the lens unit (620), and FIG. 6b is a second perspective view of the lens unit (620), and FIG. 7 is a separated perspective view of the lens unit (620) and the magnet (130).

[0121] Referring to FIGS. 1 to 7, the camera device (200) may include a first actuator (310) and an image sensing unit (330).

[0122] The first actuator (310) can move the lens assemblies (312, 313) in the optical axis direction, thereby performing auto focus and / or zoom functions. The first actuator (310) may be alternatively expressed as a “first driving unit” or an “AF and zoom driving unit.” The first actuator (310) may be arranged to be spaced apart from the image sensing unit (330) in the optical axis direction. The image sensing unit (330) can receive and detect light passing through the lens unit (620) of the first actuator (310) and convert the detected light into an electrical signal.

[0123] The first actuator (310) may include a first housing (610), a lens unit (620) disposed within the first housing (610), and a first driving unit (630) that moves the lens unit (620) in a first direction (e.g., in the optical axis direction or the Z-axis direction).

[0124] The lens unit (620) may be replaced with a “lens assembly.” For example, the lens unit (620) may include a plurality of lens assemblies.

[0125] The lens unit (620) may include two lens units (or lens assemblies) (622, 624). For example, the lens assembly (622) and the lens assembly (623) may be arranged in a first direction. In another embodiment, the lens unit (620) may include one lens assembly or three or more lens assemblies. The first actuator (310) may further include a lens assembly (640) disposed between the lens unit (620) and the second actuator (320). For example, the lens assembly (640) may be a fixed lens assembly that does not move in the optical axis direction and has a fixed position.

[0126] The lens assembly (640) may include a lens array (642). For example, the lens assembly (640) may further include a lens barrel (641) coupled with the lens array (642). In addition, the lens assembly (640) may further include a third housing (643) coupled with the lens barrel (641). The third housing (643) may be disposed between the first housing (610) and the second housing (50), and may be coupled with at least one of the first housing (610) and the second housing (50). For example, at least one first coupling hole (643A) may be formed on the front side of the third housing (643) to be coupled with at least one coupling protrusion (46A) of the first housing (610). In addition, a second coupling hole may be formed on the rear side of the third housing (643) to be coupled with at least one coupling protrusion (52A) of the second housing (50).

[0127] Although the lens assembly (640) is represented as being included in the first actuator (310), in other embodiments, the lens assembly may be represented as not being included in the first actuator (310). In other embodiments, the lens assembly (640) may be omitted.

[0128] In another embodiment, any one of 640, 622, and 624 may be represented as a “first lens assembly” or a “first lens group”, another one of 640, 622, and 624 may be represented as a “second lens assembly” or a “second lens group”, and the remaining one of 640, 622, and 624 may be represented as a “third lens assembly” or a “third lens group”. In another embodiment, 610 may be represented as any one of the “first to third housings”, 50 may be represented as any one of the “first to third housings”, and 643 may be represented as any one of the “first to third housings”.

[0129] In an embodiment, the lens assembly (640) may be a fixed lens group, and each of the lens assembly (622) and the lens assembly (624) may include a moving lens group or lens groups. For example, the lens assembly (640) may perform a focal function that focuses parallel light at a specific location. In addition, the lens assembly (622) may perform a variator function that refocuses the image focused by the lens assembly (640), which is a condenser, at another location. Meanwhile, in the lens assembly (622), the distance to the subject or the image distance may change significantly, so the magnification may change significantly, and the lens assembly (622), which is a variator, may play an important role in changing the focal length or magnification of the optical system. Meanwhile, the image focused by the lens assembly (6220), which is a variator, may slightly differ depending on the location.

[0130] Additionally, the lens assembly (624) may perform a position compensation function for the image formed by the variable lens assembly (622). For example, the lens assembly (624) may perform a compensator function that accurately forms the image formed by the variable lens assembly (622) onto the pixels of the image sensor (540). For example, the lens assembly (622) may be a zoom lens assembly that performs a zooming function, and the lens assembly (624) may be a focus lens assembly that performs a focusing function.

[0131] The first housing (610) may be positioned between the second housing (50) and the image sensor unit (330) (e.g., sensor base (550)). The first housing (610) may also be expressed as a “housing,” “base,” or “holder.”

[0132] The first housing (610) may have a polyhedral (e.g., rectangular parallelepiped) shape having a space therein to accommodate the lens unit (620) and the first driving unit (630). The lens unit (620) may be placed within the first housing (610).

[0133] For example, the first housing (610) may include a body (612) including an upper portion (142A) (or upper plate), a lower portion (142B) (or lower plate), and a plurality of side portions (141-1 to 141-4) disposed between the upper portion (142A) and the lower portion (142B).

[0134] The sides (141-1 to 141-4) may be alternatively referred to as “side plates” or “side walls.” For example, the sides (141-1) and (141-2) may face each other in a first direction or be positioned opposite each other, and the sides (141-3) and (141-3) may face each other in a third direction or be positioned opposite each other.

[0135] A first opening (41A) (or first hole) may be formed in a side portion (141-1) of the first housing (610) to expose one end of the lens portion (620). A second opening (41B) (or second hole) may be formed in a side portion (141-2) of the first housing (610) to expose the other end of the lens portion (620). In addition, a third opening (41C) (or third hole) may be formed in a side portion (141-3) of the first housing (610) to place or mount the first coil (120A). A fourth opening (41C) (or fourth hole) may be formed in a side portion (141-4) of the first housing (610) to place or mount the second coil (120B). Each of the third and fourth openings (41C, 41D) is in the form of a through hole, but may be in the form of a groove in other embodiments.

[0136] At least one first coupling protrusion (45A) may be formed on the side (141-3) of the first housing (610) to be coupled with the first circuit board (192) of the substrate portion (190). For example, at least one first coupling protrusion (45A) may protrude from the outer surface of the side (141-3). At least one second coupling protrusion (45B) may be formed on the side (141-4) of the first housing (610) to be coupled with the second circuit board (194) of the substrate portion (190). For example, at least one second coupling protrusion (45B) may protrude from the outer surface of the side (141-4).

[0137] The first housing (610) may include guide parts (614A, 614B) for guiding the movement of the lens part (620). The first guide part (614A) may support and guide the lens assembly (622) when the lens part (620) moves by a zooming operation. The second guide part (614B) may support and guide the lens assembly (624) when the lens part (620) moves by a zooming operation.

[0138] For example, the first housing (610) may include a first guide portion (614A) positioned on one side of the lens portion (620) and a second guide portion (614B) positioned on the other side of the lens portion (620). The first guide portion (614A) may be positioned between the lens portion (620) and the side portion (141-3), and the second guide portion (614b) may be positioned between the lens portion (620) and the side portion (141-4).

[0139] The first guide portion (614A) may include guide protrusions (44A, 44B) for guiding the lens portion (622). The second guide portion (614B) may include guide protrusions (44C, 44D) for guiding the lens portion (624). For example, the first guide protrusion (44A) may be arranged on the inner surface of the lower portion (142B) of the first housing (610), and the second guide protrusion (44B) may be arranged on the inner surface of the upper portion (142A) of the first housing (610) corresponding to the first guide protrusion (44A) in the optical axis direction. The third guide protrusion (44C) can be arranged on the inner surface of the lower portion (142B) of the first housing (610), and the fourth guide protrusion (44D) can be arranged on the inner surface of the upper portion (142A) of the first housing (610) corresponding to the third guide protrusion (44C) in the direction of the optical axis.

[0140] The first guide portion (614A) may include at least one first guide groove (212A) corresponding to the ball member (12A). The second guide portion (614B) may include at least one second guide groove (212B) corresponding to the ball member (12B). Here, the guide groove may be expressed as a “rail” or a “groove.” For example, the first guide groove (212A) may be formed on the inner surface of the first guide portion (614A), and the second guide groove (212B) may be formed on the inner surface of the second guide portion (614B). In this case, the inner surface of each of the first and second guide portions (614A, 614B) may be a surface facing the lens portion (620).

[0141] In another embodiment, each of the first and second guide grooves may be formed on at least one of the upper and lower sides of the inner surface of each of the side portions (141-3, 141-4) of the first housing (610).

[0142] An opening (621) exposing a portion of the lens portion (620) may be formed in the upper portion (142A) of the first housing (610), and the first housing (610) may further include a cover (614) covering the opening (621). In other embodiments, the opening (621) may not be formed, and the cover (614) may be omitted.

[0143] The lens unit (620) may include a lens assembly (622) that moves along a first guide unit (614A) and a lens assembly (624) that moves along a second guide unit (614B). The lens assembly (622) may include a first lens holder (29) and a second lens array (49) (or a second lens group) arranged in the first lens holder (29). The lens holder may be alternatively expressed as a “bobbin.” The second lens array (49) may include a single lens or a plurality of lenses. The first lens holder (29) may include a first lens barrel (29A) in which the second lens array (49) is arranged and a first support unit (29B) that is coupled to the first lens barrel (29A). For example, the first lens barrel (29A) may have a barrel shape and may include an opening (29C) (or hole) for coupling the second lens array (49).

[0144] The first side (or first surface) of the first support portion (29B) can be coupled to the first lens barrel (29A). The first support portion (29B) can correspond to, face, or overlap the first guide portion (614A) in the third direction. A first mounting portion (30A) for arranging or mounting the first magnet (130A) can be formed on the second side (or second surface) of the first support portion (29B). The second side (or second surface) of the first support portion (29B) can be a surface facing the first guide portion (614A) and can be an opposite surface of the first side (or first surface) of the first support portion (29B). For example, the first mounting portion (30A) may include a first mounting surface (11A) formed in one area (e.g., a central area) of the second side (or second surface) of the first support portion (29B) and at least one first supporting protrusion (11B) protruding from the first mounting surface (11A). In FIG. 18, the first mounting portion (30A) includes four first supporting protrusions formed at four corners of the second side of the first support portion (29B), and the four first supporting protrusions may support the first magnet (130A). In other embodiments, the number of first supporting protrusions of the first mounting portion may be one or two or more.

[0145] The first support member (29B) may include at least one first groove (13A) (or first guide groove) for accommodating at least a portion of the first cloud member (12A). For example, at least one first groove (13A) may correspond to, face, or overlap at least one first guide groove (212A) of the first guide portion (614A). For example, two first grooves spaced apart from each other may be formed on the mounting surface (11A) of the first mounting portion (30A), and two first grooves spaced apart from each other may be formed below the mounting surface (11B). In another embodiment, two grooves formed above or below the mounting surface (11B) may be connected to each other to form one groove. For example, the number of grooves may be equal to the number of balls (B11 to B14), but is not limited thereto.

[0146] The lens assembly (624) may include a second lens holder (39) and a third lens array (59) (or a third lens group) disposed in the second lens holder (39). The third lens array (59) may include a single lens or a plurality of lenses. The plurality of lenses included in each of the second and third lens arrays (49, 59) may be sequentially disposed or arranged in a first direction. For example, each of the second and third lens arrays (49, 59) may include various types of optical lenses. For example, each of the second and third lens arrays (49, 59) may include at least one of a front lens having positive power and a rear lens having negative power. The distance in the optical axis direction between the second lens group and the third lens group may be varied by the first driving unit (630).

[0147] The second lens holder (39) may include a second lens barrel (39A) on which a third lens array (59) is arranged, and a second support portion (39B) coupled with the second lens barrel (39A). For example, the second lens barrel (39A) may have a barrel shape and may include an opening (39C) (or hole) for coupling the second lens array (49). A first side (or first surface) of the second support portion (39B) may be coupled to the second lens barrel (39A). The second support portion (39B) may correspond to, face, or overlap with the body (63A) of the second guide portion (614B) in the third direction. A second mounting portion (30B) may be formed on the second side (or second surface) of the second support portion (39B) on which a second magnet (130B) is arranged or mounted. The second side (or second surface) of the second support portion (39B) may be a surface facing the second guide portion (614B) and may be an opposite surface of the first side (or first surface) of the second support portion (39B).

[0148] For example, the second anchoring portion (30B) may include a second anchoring surface formed in one area (e.g., a central area) of the second side (or second surface) of the second support portion (39B) and at least one second support protrusion protruding from the second anchoring surface. The description of the first anchoring surface (11A) and the first support protrusion (11B) of the first support portion (29B) may be applied or mutatis mutandis to the second anchoring surface and the second support protrusion of the second support portion (29B).

[0149] The second support member (39B) may include at least one second groove (13B) (or second guide groove) for accommodating at least a portion of the second cloud member (12B). For example, at least one second groove (13B) may correspond to, be opposite to, or overlap at least one second guide groove (212B) of the second guide member (614B). The description of the first groove (13A) of the first support member (30A) may be applied or mutatis mutandis to the second groove (13B) of the second support member (30B).

[0150] Each of the first and second guide grooves (212A, 212B) and the first and second grooves (13A, 13B) may have a V or U shape, but is not limited thereto, and may have a shape that makes contact with the balls (B11 to B14, B21 to B24) at two or more points. The lens assemblies (622, 624) can be prevented from decentering or tilting when moving by the first and second guide grooves (212A, 212B) and the first and second grooves (13A, 13B). As a result, the alignment between the plurality of lens arrays is well matched, preventing the change in the angle of view or the occurrence of out-of-focus, so that the image quality or resolution of the camera device (200) can be significantly improved.

[0151] The first actuator (310) may further include a cloud member (12A, 12B) disposed between the first housing (610) and the lens unit (620). The cloud member (12A, 12B) may be disposed between the guide member (614A, 614B) of the first housing (610) and the lens unit (620). For example, the cloud member (12A, 12B) may be disposed between the guide member (614A, 614B) of the first housing (610) and the groove (13A, 13B) of the support member (39A, 39B) of the lens unit (620).

[0152] The cloud member (12A, 12B) may be expressed as a “ball member”, “ball”, or “ball bearing”. For example, the cloud member (12A, 12B) may include at least one ball. For example, the cloud member (12A, 12B) may include a plurality of balls (B11 to B14, B21 to B24).

[0153] The cloud members (12A, 12B) can be in contact with the first housing (610) and the lens unit (620) and can support the lens unit (620). When the lens unit (620) moves in the first direction, the cloud members (12A, 12B) can reduce friction between the lens unit (620) and the first housing (610) by performing a rolling motion between the lens unit (620) and the first housing (610). That is, by the rolling motion of the cloud members (12A, 12B), the lens unit (620) can be moved in a sliding manner in the first direction along the first and second guide members (614A, 614B) by coming into contact with the cloud members (12A, 12B). For example, the cloud members can include a first cloud member (12A) and a second cloud member (12B). The first cloud member (12A) may be disposed between the first guide member (614A) of the first housing (610) and the lens assembly (622) (e.g., the first support member (29B)). The second cloud member (12B) may be disposed between the second guide member (614B) of the first housing (610) and the lens assembly (624) (e.g., the second support member (39B)).

[0154] The first cloud member (12A) may include a plurality of balls (B11 to B14), and the second cloud member (12B) may include a plurality of balls (B21 to B24). Each of the balls (B11 to B14, B221 to B24) may be made of a metal material, a plastic material, or a resin material, but is not limited thereto. Each of the balls (B11 to B14, B221 to B24) may have a circular shape and may have a diameter sufficient to support the movement of the lens unit (620).

[0155] Next, the first driving unit (630) will be described.

[0156] The first driving unit (630) can move the lens assembly (622) in the first direction and move the lens assembly (624) in the first direction. For example, the first driving unit (630) can move at least one lens group, for example, the second lens group or the third lens group, in the first direction or the optical axis direction.

[0157] The first driving unit (630) may include a magnet (130) disposed in the lens unit (620) and a coil (120) disposed in the first housing (610). For example, the magnet (130) may include a first magnet (130A) disposed in the lens assembly (622) and a second magnet (130B) disposed in the lens assembly (624).

[0158] For example, the first magnet (130A) may be placed in the first lens holder (29) of the lens assembly (622), and the second magnet (130B) may be placed in the second lens holder (39) of the lens assembly (624). For example, the first magnet (130A) may be placed in the first mounting portion (30A) of the first support portion (29B) of the first lens holder (29), and the second magnet (130B) may be placed in the second mounting portion (30B) of the second support portion (39B) of the second lens holder (39).

[0159] For example, each of the first and second magnets (130A, 130B) may be a two-pole magnetizing magnet including one N pole and one S pole. In another embodiment, each of the first and second magnets (130A, 130B) may be a four-pole magnetizing magnet including two N poles and two S poles.

[0160] The coil (120) may include a first coil (120A) that corresponds to, opposes, or overlaps with the first magnet (130A) in a third direction and is disposed on a side (141-3) of the first housing (610), and a second coil (120B) that corresponds to, opposes, or overlaps with the second magnet (130B) in a third direction and is disposed on a side (141-4) of the first housing (610).

[0161] For example, the first coil (120A) may include a hollow (3A). The first coil (120A) may include a closed curve or ring shape having the hollow (3A) (or hole). The second coil (120B) may include a hollow (3B). The second coil (120B) may include a closed curve or ring shape having the hollow (3B) (or hole). Each of the first coil (120A) and the second coil (120B) may include a body having the hollow (3A, 3B). Each of the first coil (120A) and the second coil (120B) may include a body having the hollow (3A, 3B). The bodies of each of the first coil (120A) and the second coil (120B) may be a closed curve or ring shape.

[0162] For example, each of the first coil (120A) and the second coil (120B) may be in the form of a coil ring wound clockwise or counterclockwise around (or centered on) a third axis parallel to the third direction. For example, the first coil (120A) may have a ring-shaped body wound around an axis perpendicular to the first surface (75A) of the first circuit board (192). For example, the second coil (120B) may have a ring-shaped body wound around an axis perpendicular to the first surface (76A) of the second circuit board (194).

[0163] For example, each of the first coil (120A) and the second coil (120B) may be in the form of a single coil wire wound multiple times. For example, each of the first coil (120A) and the second coil (120B) may be in the form of a winding coil, a coil bundle, a coil body, or a coil block.

[0164] For example, the N pole and the S pole of the first magnet (130A) may be arranged to face the first coil (120A), and the N pole and the S pole of the second magnet (130B) may be arranged to face the second coil (120B). For example, the hollow or hole of each of the first and second coils (120A, 120B) may face the first and second magnets (130A, 130B) in a third direction.

[0165] A first driving signal (e.g., a first current) may be applied to the first coil (120A), and a second driving signal (e.g., a second current) may be applied to the second coil (120B). The lens assembly (622) may be moved in the first direction by an electromagnetic force resulting from the interaction between the first coil (120A) and the first magnet (130A). In addition, the lens assembly (624) may be moved in the first direction by an electromagnetic force resulting from the interaction between the second coil (120B) and the second magnet (130B).

[0166] By controlling the first driving signal and the second driving signal, the movement of each of the lens assembly (622) and the lens assembly (624) can be controlled. As the movement of each of the lens assembly (622) and the lens assembly (624) is controlled, the position (or displacement) of each of the lens assembly (622) and the lens assembly (624) can be controlled, thereby performing zooming and auto-focusing of the camera device (200).

[0167] The first driving unit (630) may further include a first yoke (19-1) disposed in the first lens holder (29) and a second yoke (19-2) disposed in the second lens holder (39). The first yoke (19-1) may increase an electromagnetic force due to an interaction between the first magnet (130A) and the first coil (120A), and the second yoke (19-2) may increase an electromagnetic force due to an interaction between the second magnet (130B) and the second coil (120B). The driving force for moving the lens unit (620) may be improved by the first and second yokes (19-1, 19-2), thereby reducing power consumption.

[0168] For example, the first yoke (19-1) may be disposed between the first magnet (130A) and the first lens holder (29), and the second yoke (19-2) may be disposed between the second magnet (130B) and the second lens holder (39). For example, the first yoke (19-1) may be disposed on the first mounting portion (30A) of the first support portion (29B), and the second yoke (19-2) may be disposed on the second mounting portion (30B) of the second support portion (39B). For example, the first yoke (19-1) may include a first portion (19A) facing the first magnet (130A) in the third direction and disposed on the first mounting surface (11A), and a second portion (19B) extending from at least one of one end and the other end of the first portion (19A). For example, the second part (19B) may include a second-1 part supporting one end of the first magnet (130A) and a second-2 part supporting the other end of the first magnet (130A). The descriptions of the first part (19A) and the second part (19B) of the first yoke (19-1) may be applied or applied to the second yoke (19-2).

This is a separated perspective view of the substrate (194) and the yoke (94), and FIG. 10c is a combined perspective view of the second circuit substrate (194) and the yoke (94).

[0170] Referring to FIGS. 8A to 10C, the first driving unit (630) may further include a substrate (190) electrically connected to the first coil (120A) and the second coil (120B). For example, the substrate (190) may be a circuit board or a printed circuit board. The substrate (190) may be disposed in the first housing (610). The first circuit board (192) may be disposed in the first housing (610). The second circuit board (194) may be disposed in the first housing (610).

[0171] For example, the substrate (190) may include a first circuit board (192) disposed on a side (141-3) of the first housing (610) and a second circuit board (194) disposed on a side (141-4) of the first housing (610).

The first surface (75A) of the first circuit board (192) may be a surface facing the side (141-3) of the first housing (610) or the first magnet (130A). For example, the first surface (75A) may be a surface facing one side of the lens unit (620).

[0174] The second coil (120B) may be placed or mounted on the first surface (76A) of the second circuit board (194). At this time, the first surface (76A) of the second circuit board (194) may be a surface facing the side (141-4) of the first housing (610) or the second magnet (130B). For example, the first surface (76A) may be a surface facing the other side of the lens unit (620).

[0175] A first circuit board (192) may be electrically connected to a first coil (120A). The first circuit board (192) may include two pads (19A, 19B) electrically connected to the first coil (120A). The first pad (19A) may be disposed on a first surface (75A) of the first circuit board (192). The second pad (19B) may be disposed on a second surface (75B) of the first circuit board (192).

The first pad (19A) can be exposed to the first surface (75A) of the first circuit board (192), and the second pad (19B) can be exposed to the second surface (75B) of the first circuit board (192).

[0176] The first magnet (130A) may be positioned closer to the first pad (19A) than to the second pad (19B). Among the first and second pads (19A, 19B), the first pad (19A) may be positioned closer to the first magnet (130A) than to the second pad (19B).

[0177] For example, the first pad (19A) may be positioned outside the hollow (3A) of the first coil (120A). For example, the first pad (19A) may not overlap the hollow (3A) of the first coil (120A) in the direction in which the first coil (120A) and the first magnet (130A) face each other.

[0178] A portion (112A) (or “first portion”) of the first coil (120A) may be connected to a first pad (19A) of the first circuit board (192), and another portion (112B) (or “second portion”) of the first coil (120A) may be connected to a second pad (19B) of the first circuit board (192).

A portion (112A) (or “first portion”) of the first coil (120A) may be coupled to the first pad (19A).

[0180] For example, a portion (112A) of the first coil (120A) may be conductively bonded to a first pad (19A) of the first circuit board (192) by solder or a conductive adhesive. For example, a portion (112A) of the first coil (120A) may extend from a ring-shaped body.

[0181] Another portion (112B) (or “second portion”) of the first coil (120A) may be electrically or conductively connected to a second pad (19B) disposed on a second surface (75B) of the first circuit board (192). Another portion (112B) (or “second portion”) of the first coil (120A) may pass through the first circuit board (192).

[0182] Another portion (112B) (or “second portion”) of the first coil (120A) may be coupled to the second pad (19B). For example, the other portion (112B) of the first coil (120A) may be conductively coupled to the second pad (19B) of the first circuit board (192) by solder or a conductive adhesive. The second pad (19B) may be disposed within an area of ​​the second surface (75B) of the first circuit board (192) corresponding to or opposite the hollow (3A) of the first coil (120A). For example, the other portion (112B) of the first coil (120A) may extend from a ring-shaped body.

[0183] The first circuit board (192) may include a hole (18A) for at least a portion of the first coil (120A) to pass through.

At least a portion of the first coil (120A) may be positioned within the hole (18A) of the first circuit board (192). An area of ​​another portion (112B) of the first coil (120A) may be positioned within the hole (18A) of the first circuit board (192).

[0184] Another part (112B) of the first coil (120A) may overlap with the hollow (3A) of the first coil (120A) in a direction in which the first coil (120A) and the first magnet (130A) face each other.

[0213] Fig. 11a is a cross-sectional perspective view of a first circuit board (192), a first coil (120A), and a first magnet (130A), and Fig. 11b is a cross-sectional view of the first circuit board (192), the first coil (120A), and the first magnet (130A) of Fig. 11a.

[0214] Referring to FIGS. 11A and 11B, the length (H1) of the hole (18A) of the first circuit board (192) in the first direction or in the direction parallel to the first surface (75A) (or the second surface (75B)) of the first circuit board (192) may be smaller than the length (H2) of the hollow (3A) of the first coil (120A) in the first direction or in the direction parallel to the first surface (75A).

[0215] The length (H3) of the hole (2A) of the first yoke (92) in the first direction or in the direction parallel to the first surface (75A) (or the second surface (75B)) of the first circuit board (192) may be greater than the length (H1). Also, for example, H3 may be less than or equal to H1. H3 may be less than or equal to H2. In other embodiments, H3 may be greater than H2.

[0216] The length of the first coil (120A) in the optical axis direction or the height of the first coil (120A) in the optical axis direction based on the first surface (75A) may be greater than the separation distance (K1) between the first coil (120A) and the first magnet (130A). In another embodiment, the length of the first coil (120A) in the optical axis direction or the height of the first coil (120A) in the optical axis direction based on the first surface (75A) may be equal to the separation distance between the first coil (120A) and the first magnet (130A).

[0217] The thickness (or length) of the first coil (120A) in the direction in which the first coil (120A) and the first magnet (130A) face each other may be greater than the separation distance (K1) between the first coil (120A) and the first magnet (130A). This may enhance the electromagnetic force between the first coil (120A) and the first magnet (130A). In another embodiment, the thickness (or length) of the first coil (120A) in the direction in which the first coil (120A) and the first magnet (130A) face each other may be equal to or less than the separation distance (K1) between the first coil (120A) and the first magnet (130A).

[0218] The inner surface (7A) (or inner side) of the first coil (120A) may be located inside the edge (7B) of the hole (18A) of the first circuit board (192). The inner surface (7A) (or inner side) may be the inner surface (or inner side) of a coil wire located at the innermost position among the wound coil wires of the first coil (120A). Alternatively, the inner surface (7A) may correspond to the edge of the hollow (3A) of the first coil (120A).

[0219] In addition, the edge (7B) of the hole (18A) of the first circuit board (192) may overlap the first coil (120A) in a direction in which the first coil (120A) and the first magnet (130A) face each other or in a direction perpendicular to the first surface (75A) of the first circuit board (192). A straight line (101) that is perpendicular to the first surface (75A) of the first circuit board (192) and passes through the center of the hollow (3A) of the first coil (120A) may be positioned closer to the inner surface (7A) (or inner side) of the first coil (120A) than the edge (7B) of the hole (18A) of the first circuit board (192). Alternatively, the distance between the straight line (101) and the edge (7B) of the hole (18A) of the first circuit board (192) may be greater than or equal to the distance between the straight line (101) and the inner surface (7A) of the first coil (120A).

[0220] In another embodiment, the inner surface (7A) (or inner side) of the first coil (120A) may be aligned or coincident with the edge (7B) of the hole (3A) of the first circuit board (192). Alternatively, the inner surface (7A) (or inner side) of the first coil (120A) may be positioned to overlap the edge (7B) of the hole (3A) of the first circuit board (192) in the direction of the optical axis.

[0221] This allows another part (112B) of the first coil (120A) to easily pass through the hole (3A) of the first circuit board (192). In addition, the other part (112B) of the first coil (120A) includes a portion bent from the coil ring, and the area where this bent portion rubs against the first circuit board (192) is reduced, thereby preventing the other part (112B) of the first coil (120A) from being disconnected. In another embodiment, the inner surface (7A) (or inner side) of the first coil (120A) may be positioned outside the inner surface (7B) of the hole (3A) of the first circuit board (192).

[0222] In the embodiment, a part (112A) of the first coil (120A) is electrically bonded to a first pad (19A) disposed on a first surface (75A) of the first circuit board (192), and another part (112B) of the first coil (120A) is electrically bonded to a second pad (19B) disposed on a second surface (75B) of the first circuit board (192) by passing through a hole (3A) of the first circuit board (192). Therefore, a decrease in the distance (K1) between the first coil (120A) and the first magnet (130A) due to the other part (112B) of the first coil (120A) can be prevented, thereby preventing contact between the first coil (120A) and the first magnet (130A). In the embodiment, tilting of the lens unit (622) caused by contact between the first coil (120A) and the first magnet (130A) can be prevented.

[0223] The description of FIGS. 11A and 11B may be applied or analogically applied to the second coil (120B), the second circuit board (194), and the second yoke (194).

The first position sensor (71) may be arranged or mounted on the first circuit board (192) and may be electrically connected to the first circuit board (192). The second position sensor (72) may be arranged or mounted on the second circuit board (194) and may be electrically connected to the second circuit board (194).

[0226] For example, the first position sensor (71) may be placed or mounted on the first surface (75A) of the first circuit board (192), and the second position sensor (72) may be placed or mounted on the first surface (76A) of the second circuit board (194). For example, the first position sensor (71) may be placed within the hollow (3A) of the first coil (120A), and the second position sensor (72) may be placed within the hollow (3B) of the second coil (120B).

[0227] For example, the first position sensor (71) may face or overlap the first magnet (130A) in the third direction. For example, the first position sensor (71) may be placed on the opposite side of the first magnet (130A). The first position sensor (71) may detect the strength of the magnetic field of the first magnet (130A). For example, the first position sensor (71) may detect the movement of the first magnet (130A) in the direction of the optical axis.

[0228] The second position sensor (72) may face or overlap the second magnet (130B) in the third direction. For example, the second position sensor (72) may be placed on the opposite side of the second magnet (130B). The second position sensor (72) may detect the strength of the magnetic field of the second magnet (130B). For example, the second position sensor (72) may detect the movement of the second magnet (130B) in the direction of the optical axis.

[0229] For example, the first position sensor (71) may include a first sensor (71A) and a second sensor (71B). For example, each of the first and second sensors (71A, 71B) may be a hall sensor. For example, the first sensor (71A) and the second sensor (71B) may be arranged to be spaced apart from each other in a first direction. For example, the second position sensor (72) may include a third sensor (72A) and a fourth sensor (72B). For example, each of the third and fourth sensors (72A, 72B) may be a hall sensor. For example, the third sensor (72A) and the fourth sensor (72B) may be arranged to be spaced apart from each other in a first direction. In FIGS. 2A and 2B, each of the first position sensor (71) and the second position sensor (72) includes two sensors, but in other embodiments, each of the first position sensor and the second position sensor may include one sensor, wherein one sensor may be a Hall sensor or may be in the form of a driver IC including a Hall sensor.

[0230] The camera device (200) may include a memory. For example, the memory may be a non-volatile memory, such as an Electrically Erasable Programmable Read-Only Memory (EEPROM). For example, the memory may be arranged or mounted on the substrate (190, 530) and may be electrically connected to the substrate (190, 530). For example, the memory may store data required for driving the driving unit. At this time, the driving unit may include at least one of a first driving unit (630) and a second driving unit (70). The memory may store at least one of data of a first position sensor (71) corresponding to a movement range of a lens assembly (622) and data of a second position sensor (72) corresponding to a movement range of a lens assembly (624). At this time, the data of the first position sensor (71) may be data (or a reference code value) regarding an output of the first position sensor (71) corresponding to a movement range of the lens assembly (622) obtained through calibration. Additionally, the data of the second position sensor (72) may be data (or reference code value) regarding the output of the second position sensor (72) corresponding to the movement range of the lens assembly (624) obtained through calibration.

[0231] In addition, the memory can store data of the first OIS position sensor (240A, 240B) corresponding to the second-axis (X-axis) tilting range of the OIS moving unit. At this time, the data of the first OIS position sensor (240A, 240B) may be a reference code value regarding the output of the first OIS position sensor (240A, 240B) corresponding to the second-axis (X-axis) tilting range of the OIS moving unit obtained through calibration. In addition, the memory can store data of the second OIS position sensor (240C) corresponding to the third-axis (Y-axis) tilting range of the OIS moving unit.

[0233] Referring to FIG. 4A, the first actuator (310) may further include glass (glass, 115) positioned in front of the lens portion (620). For example, the glass (115) may be positioned within the first housing (610) to cover the first opening (41A) of the first housing (610), thereby protecting the lens portion (620) and preventing foreign substances from entering the second housing.

[0234] The image sensing unit (330) may include an image sensor (540) that receives and detects light passing through the lens assemblies (622, 624, 640) of the first actuator (310) and converts the detected light into an electrical signal. For example, the image sensor (540) may include an imaging area for detecting light. Here, the imaging area may be expressed as an effective area, a light-receiving area, or an active area. For example, the imaging area may include a plurality of pixels on which an image is formed.

The substrate (530) may be provided with circuit elements, passive elements, active elements, or circuit patterns. In another embodiment, the control unit (542) may be disposed on the substrate (530).

[0239] The image sensing unit (330) may further include a sensor base (550) disposed between the substrate unit (530) and the first actuator (310) and a filter (560) disposed on the sensor base (550). For example, the sensor base (550) may be disposed between the substrate unit (530) and the first housing (610). The sensor base (550) may be coupled, attached, or fixed to the first surface (531) of the substrate unit (530) by an adhesive (545). The lower portion or bottom surface of the sensor base (550) may be coupled to the substrate unit (530) by the adhesive (545). For example, at least one coupling protrusion (551) may be formed on the lower portion or bottom surface of the sensor base (550), and at least one hole (530A) may be formed on the substrate unit (530) to be coupled with the at least one coupling protrusion (551).

[0240] The sensor base (550) may include a mounting portion (550A) for placing or mounting the filter (610). For example, the mounting portion (550A) may be formed on a first surface of the sensor base (550). The first surface of the sensor base (550) may be a surface facing the first housing (610) in the optical axis direction. For example, the mounting portion (500A) may be in the form of a recess, cavity, or hole that is sunken from the first surface of the sensor base (550), but in another embodiment, the mounting portion may be in the form of a protrusion that protrudes from the first surface of the sensor base (550). The sensor base (550) may also be expressed as a “holder.”

[0241] The filter (560) may be placed on the sensor base (550). The filter (560) may be coupled to the sensor base (550). For example, the filter (560) may be placed on the mounting portion (550A) of the sensor base (550). For example, the mounting portion (550A) of the sensor base (550) may include an inner surface and a bottom surface, and the filter (560) may be placed on the bottom surface of the mounting portion (500A) of the sensor base (550). The sensor base (550) may include an opening (552) (or a through hole) so that light passing through the filter (560) may be incident on the image sensor (540). The opening (552) may correspond to, face, or overlap the image sensor (550) (e.g., an imaging area). For example, the opening (552) may be formed on the bottom surface of the mounting portion (550A). For example, the area of ​​the opening (552) may be smaller than the area of ​​the upper or lower surface of the filter (560).

[0242] The filter (560) may block light of a specific frequency band from passing through the lens unit (620) from entering the image sensor (540). For example, the filter (560) may be an infrared blocking filter, but is not limited thereto. For example, the filter (560) may be arranged parallel to an xy plane perpendicular to the first direction. For example, the filter (560) may be attached to the bottom surface of the mounting portion (550A) of the sensor base (550) by an adhesive material (not shown), such as UV epoxy. The filter (560) and the image sensor (540) may be arranged spaced apart from each other so as to face each other in the first direction.

[0243] Although the embodiment of FIG. 2A includes a zoom lens assembly (622) that performs a zoom function and a focus lens assembly (624) that performs an autofocus function, in other embodiments, the zoom lens assembly (622) may be omitted and the focus lens assembly (624) may be included. For example, the first actuator according to other embodiments may be a fixed zoom actuator that performs an autofocus function.

[0244] Fig. 12a shows the combination of the first coil (120A1) and the first circuit board (192-1) according to the first comparative example.

[0245] Referring to Fig. 12A, when the first coil (120A1) is wound in a coil ring shape, a start line (23A) and an end line (23B) are generated. The start line (23A) can be electrically coupled to a pad formed on the first surface of the first circuit board (192-1), and at this time, the pad can be located within the hollow (4A) of the first coil (120A1) or outside the hollow (4A) of the first coil (120A1).

[0246] When the pad of the first circuit board (192-1) is located within the hollow space (4A) of the first coil (120A1), the distance (d1) between the first coil (120A) and the first magnet (130A) is not affected by the starting line (23A), but soldering between the starting line (23A) and the pad of the first circuit board (129-1) is very difficult due to the height (or thickness) of the first coil (120A1). In addition, since it is impossible to place other components (e.g., the first position sensor (e.g., 71)) within the hollow space of the first coil (120A1), spatial restrictions on component installation may be imposed.

[0247] In order to solve this problem, as in the first comparative example, the pad (P1) of the first circuit board (192-1) may be located outside the hollow (4A) of the first coil (120A1), and the starting line (23A) may be located on the lower side of the coil ring of the first coil (120A1) (or on one side of the coil ring facing the first surface of the first circuit board (192-1)) and may be coupled with the pad (P1) of the first circuit board (192-1). However, in the first comparative example, the first coil (120A1) may be lifted from the first surface of the first circuit board (192-1) by the starting line (23A), and as a result, the coupling force between the first coil (120A1) and the first circuit board (192-1) may be weakened, causing the first coil (120A1) to detach from the first circuit board (192-1).

[0248] Fig. 12b shows the combination of the first coil (120A1) and the first circuit board (192-1) according to the second comparative example.

[0249] Referring to FIG. 12b, the starting line (23A) of the first coil (120A1) may be located on the upper side of the coil ring (or the other side of the coil ring facing the first magnet (130A)) and may be coupled with the pad (P1) of the first circuit board (192-1). However, in the second comparative example of FIG. 12b, since the starting line (23A) is arranged adjacent to the first magnet (130A), the distance (d2) between the first coil (120A) and the first magnet (130A) may be reduced by the thickness of the starting line (23A). That is, compared to the distance (d1) of the first comparative example of FIG. 12a, the distance (d2) between the first magnet (130A) and the first coil (120A1) in FIG. 12b may be smaller than d1. In the second comparative example of Fig. 12b, because the distance (d2) between the first magnet (130A) and the first coil (120A1) is reduced due to the starting line (23A), contact or collision between the first coil (120A1) and the first magnet (130A) may occur during the zoom operation or auto focus operation.

[0250] Figure 12c shows the simulation results in which contact occurs between the first coil (120A1) and the first magnet (130A) in the second comparative example of Figure 12b.

[0251] Referring to FIG. 12c, due to the arrangement of the starting line (23A) according to Comparative Example 2, contact may occur between the first coil (120A1) and the first magnet (130A), which may cause tilting of the lens assembly (622, 624) and deteriorate the performance of the zoom / auto focus.

[0252] In the embodiment, since the starting line portion (112B) of the first coil (120A) passes through the hole (18A) of the first circuit board (192) and is coupled with the second pad (19B) arranged on the second surface (75B) (or 76B) of the first circuit board (192), the distance between the first coil (120A) and the first magnet (130A) can be prevented from being reduced. Similarly, the distance between the second coil (120B) and the second magnet (9130B) can be prevented from being reduced.

[0253] In addition, in the embodiment, contact between the first coil (120A) and the first magnet (130A) and contact between the second coil (120B) and the second magnet (120B) can be prevented during zoom or AF driving, thereby preventing tilting of the lens assemblies (622, 624).

[0254] In addition, in the embodiment, the separation distance between the first coil (120A) and the first magnet (130A) and the separation distance between the second coil (120B) and the second magnet (130B) can be designed to be small, thereby improving the driving force for zoom driving and the driving force for AF driving.

This is a functional block diagram of 200-1).

[0256] Referring to FIGS. 13 to 23, the camera device (200-1) may include a first actuator (310), a second actuator (320), and an image sensor unit (330). FIG. 13 may show an embodiment in which a second actuator (320) is added to the camera device (200).

[0257] For example, the second actuator (320) may include an optical member (40) that changes the path of light. The second actuator (320) may move the optical member (40), thereby performing an OIS (Optical Image Stabilizer) operation for performing shake correction. The second actuator (320) may be alternatively expressed as a “second driving unit” or an “OIS driving unit.” The second actuator (320) may change the path of light. The second actuator (320) may also be alternatively expressed as an optical path changing unit. 310 may be represented by one of the first and second actuators, and 320 may be represented by the other of the first and second actuators. The first actuator (310) may be arranged after the second actuator (320). The second actuator (320) can be coupled with the first actuator (310).

[0258] The second actuator (320) may include an optical member (40) that changes the path of light and a second driving unit (70) that rotates the optical member (40) by a preset angle in a direction perpendicular to the optical axis direction (e.g., the Z-axis direction) (e.g., the X-axis direction or the Y-axis direction). The optical member (40) may output the incident light to the first actuator (310). The optical member (40) may include a reflector that may change the direction in which the light travels. For example, the optical member (40) may be a prism that reflects light, but in other embodiments, the optical member may include a mirror.

[0259] The second actuator (320) may include a holder (30) for accommodating an optical member (40). The optical member (40) may be placed within the holder (30). The optical member (40) may change the optical path of incident light into an optical axis parallel to the central axis (Z) of the lens unit (620), thereby changing the incident light into parallel light, and the parallel light may pass through the lens assembly (640), the lens assembly (622), and the lens assembly (624) to reach the image sensor (540).

[0260] The optical member (40) may include an incident surface (8A) and an exit surface (8B). The optical member (40) may reflect light incident on the incident surface (8A) and emit the light through the exit surface (8B). For example, the optical member (40) may be a right-angled prism including an incident surface (8A), a reflective surface (8C), and an exit surface (8B). For example, the interior angle between the incident surface (8A) and the exit surface (8B) may be a right angle. In addition, for example, the first interior angle between the incident surface (8A) and the reflective surface (8C) and the second interior angle between the exit surface (8B) and the reflective surface (8C) may each be 30 to 60 degrees. For example, the first interior angle and the second interior angle may each be 45 degrees. Due to the change in the optical path by the optical member (40), the thickness of the camera device (200) in the direction perpendicular to the incident surface (8A) of the optical member (40) can be reduced, and thus the thickness of the mobile device or terminal (200A) on which the camera device (200) is mounted can be reduced.

[0261] The second actuator (320) may include a second housing (50) for accommodating the holder (30). The holder (30) may be disposed within the second housing (50). The second actuator (320) may include a support (60) disposed between the holder (30) and the housing (50) and supporting the holder (30) with respect to the housing (50). In addition, the second actuator (320) may include a second driving unit (70) for driving or rotating the OIS moving unit.

[0262] The holder (30) may include a mounting portion (104) for placing or mounting the optical member (40). The mounting portion (104) may be in the form of a groove and may have a mounting surface (104a) (or mounting surface) for placing the reflective surface (8C) of the optical member (40). For example, the mounting surface (104a) may be an inclined surface inclined with respect to the optical axis direction. For example, an adhesive for attaching the optical member (40) to the mounting surface (104a) of the holder (30) may be placed, and at least one groove (104b) for accommodating the adhesive may be formed in the mounting surface (104a).

[0263] For example, the holder (30) may include a first opening exposing an incident surface (8A) of the optical member (40) and a second opening exposing an exit surface (8B) of the optical member (40). For example, the first opening may be arranged on an upper side of the holder (30), and the second opening may be arranged on a side (front outer side, 31a) of the holder (30) facing the lens section (620) of the first actuator (310). The exit surface (8B) of the optical member (40) mounted on the holder (30) may be arranged to face the lens section (620) of the first actuator (310).

[0264] The upper surface (18) of the holder (30) may include a first surface (18A) and a second surface (18B) having a step in a second direction (e.g., X-axis direction) from the first surface (18A). The first surface (18A) may be positioned adjacent to or in contact with the rear outer surface (31b) of the holder (30), and the second surface (18B) may be positioned adjacent to or in contact with the front outer surface (31a) of the holder (30). The second surface (18B) may be positioned lower than the first surface (18A). For example, the second surface (18B) may be positioned closer to the lower surface (19) of the holder (30) than the first surface (18A). Since the second surface (18B) has a step with the first surface (18A), when the holder (30) tilts or rotates by a preset angle in the second direction (e.g., in the X-axis direction), spatial interference between the holder (30) and the second housing (50) can be prevented.

[0265] For example, at least one stopper (38) may be formed on the upper surface (e.g., the second surface (18B)) of the holder (30). The stopper (38) may be a projection or a protrusion protruding upward from the upper surface (e.g., the second surface (18B)) of the holder (30). For example, the stopper (38) may be formed on the upper surface of each of the first and second sides of the holder (30). The tilt or rotation of the holder (30) in the second direction may be restricted by the stopper (38). For example, the height of the upper surface of the stopper (38) may be lower than or equal to the height of the first surface (18A).

[0266] The holder (30) may include sides (or outer surfaces) (31c, 31d) that are positioned facing each other or opposite each other. For example, the mounting portion (104) may be positioned between two sides (31c, 31d) of the holder (30). For example, the two sides (31c, 31d) may be positioned opposite each other or facing each other in a third direction (e.g., the Y-axis direction).

[0267] For example, the front outer surface (31a) of the holder (30) is referred to as the outer surface of the first side of the holder (30), the rear outer surface (31b) of the holder (30) is referred to as the outer surface of the second side of the holder (30), the side (31c) of the holder (30) is referred to as the third side of the holder (30), and the side (31d) of the holder (30) is referred to as the fourth side (31d) of the holder (30). Each of the third and fourth sides (31c, 31d) of the holder (30) may include a first outer surface (19A) and a second outer surface (19B) having a step in a third direction (e.g., in the Y-axis direction) from the first outer surface (19A). The first outer side (19A) may be positioned adjacent to or in contact with the rear outer side (31b) of the holder (30), and the second outer side (19B) may be positioned adjacent to or in contact with the front outer side (31a) of the holder (30). The second outer side (19B) may be positioned closer to the inner side of the holder (30) than the first outer side (19A).

[0268] Since the second outer surface (19B) of the holder (30) has a step with the first outer surface (19A), when the holder (30) tilts or rotates by a preset angle in the third direction (e.g., the Y-axis direction), spatial interference between the holder (30) and the second housing (50) can be prevented.

[0269] For example, at least one stopper (39A) may be formed on the third and fourth sides (e.g., the second outer side surface (19B)) of the holder (30). The stopper (39A) may be a projection or a protrusion protruding from the outer side surface (e.g., the second outer side surface (19B)) of each of the third and fourth sides (31c, 31d) of the holder (30). The tilt or rotation of the holder (30) in the third direction may be restricted by the stopper (39A). For example, the protruding height of the stopper (39A) with respect to the second outer side surface (19B) may be smaller than or equal to the step difference between the first outer side surface (19A) and the second outer side surface (19B).

[0270] The lower surface (17) of the holder (30) may include a first surface (17A) and a second surface (17B) having a step in a second direction (e.g., X-axis direction) from the first surface (17A). The first surface (17A) may be positioned adjacent to or in contact with a front outer surface (31a) of the holder (30), and the second surface (17B) may be positioned adjacent to or in contact with a rear outer surface (31b) of the holder (30). The first surface (17A) may be positioned lower than the second surface (17B). For example, the second surface (17B) may be positioned closer to the upper surface (18) of the holder (30) than the first surface (17A). Since the second surface (17B) of the lower surface (17) of the holder (30) has a step with the first surface (17A), when the holder (30) tilts or rotates by a preset angle in the second direction (e.g., in the X-axis direction), spatial interference between the holder (30) and the second OIS coil (230C) can be prevented. For example, at least one stopper (41) may be formed on the lower surface (e.g., the second surface (17B)) of the holder (30). The stopper (41) may be a protrusion or a projection that protrudes downward from the lower surface (e.g., the second surface (17B)) of the holder (30). The tilt or rotation of the holder (30) in the second direction can be restricted by the stopper (41). For example, the protruding length of the stopper (38) based on the second surface (17B) may be smaller than or equal to the step between the first surface (17A) and the second surface (17B) of the lower surface (17) of the holder (30).

[0271] The holder (30) may include a first mounting groove (16A) for placing or settling the first OIS magnet (31) and a second mounting groove (16B) for placing or settling the second OIS magnet (32). For example, the first mounting groove (16A) may be formed on an outer surface (e.g., a first outer surface (19A)) of each of the third and fourth side portions (31c, 31d) of the holder (30). For example, the first mounting groove (16A) may be a groove shape that is recessed from the first outer surface (19A) of each of the third and fourth side portions (31c, 31d) of the holder (30). For example, the second mounting groove (16B) may be formed on a lower surface (17) (e.g., a second surface (16B)) of the holder (30). For example, the second fixing groove (16B) may be a groove shape sunken from the lower surface (17) of the holder (30) (e.g., the second surface (16B)).

[0272] The rear outer surface (31b) of the holder (30) may include a first surface (21a), a second surface (21b) adjacent to or in contact with a third side (31c), and a third surface (21c) adjacent to or in contact with a fourth side (31d). When viewed from the rear, the first surface (21a) may be positioned in the center, the second surface (21b) may be positioned on the left side of the first surface (21a), and the third surface (21c) may be positioned on the right side of the first surface (21a). Each of the second surface (21b) and the third surface (21c) may have a step with respect to the first surface (21a) in the first direction (e.g., the Z-axis direction). For example, the first surface (21a) may be positioned closer to the inner surface of the holder (30) than each of the second surface (21b) and the third surface (21c). For example, the second surface (21b) and the third surface (21c) may be positioned on the same plane. Or, for example, the step between the first surface (21a) and the second surface (21b) may be the same as the step between the first surface (21a) and the third surface (21c), but is not limited thereto, and in other embodiments, the two may be different from each other.

[0273] For example, a groove (106) for seating or accommodating a mover plate (61) may be formed on the rear outer surface (31b) of the second side of the holder (30). For example, the groove (106) may be positioned at the center of the rear outer surface (31b) and may be recessed from the rear outer surface (31b).

[0274] The holder (30) may be formed on a first surface (21a) of the rear outer surface (31b) and may include at least two grooves (36A, 36B) corresponding to at least two front protrusions (61B1, 61B2) of the drive plate (61). For example, the at least two grooves (36A, 36B) of the holder (30) may be arranged spaced apart from each other in a third direction and may be formed on a bottom surface of the groove (106). For example, the holder (30) may include a second groove (36B) formed on the first surface (21a) of the rear outer surface (31b) and a first groove (36A) spaced apart from the second groove (36B) and positioned above the second groove (36B). In another embodiment, the first groove may be positioned above the second groove. For example, the first groove (36A) may include a bottom surface and a plurality of side surfaces (1A to 1D). The area of ​​at least one of the plurality of side surfaces (1A to 1D) of the first groove (36A) may be different from the area of ​​at least another of the plurality of side surfaces (1A to 1D) of the first groove (36A). In another embodiment, at least two grooves (36A, 36B) may be arranged spaced apart from each other in the second direction.

[0275] For example, the two side surfaces (1C, 1D) of the first groove (36A) facing each other in the third direction may have a symmetrical shape, and the areas of the two side surfaces (1C, 1D) may be the same. In addition, the two side surfaces (1A, 1B) of the first groove (36A) facing each other in the third direction may have a symmetrical shape, and the areas of the two side surfaces (1A, 1B) may be the same. The first area of ​​each of the side surfaces (1C, 1D) of the first groove (36A) facing each other in the third direction may be different from the second area of ​​each of the side surfaces (1A, 1D) of the first groove (36A) facing each other in the second direction. For example, the first area may be smaller than the second area. In another embodiment, the first area may be larger than the second area. For example, the bottom surface of the first groove (36A) may be rectangular or oval, but is not limited thereto.

[0276] The second groove (36B) may include a bottom surface and a plurality of side surfaces. Each of the plurality of side surfaces of the second groove (36B) may have the same shape. In FIG. 6B, the number of side surfaces of the second groove (36B) is four, but is not limited thereto, and in other embodiments, may be five or more. For example, the areas of the plurality of side surfaces of the second groove (36B) may be the same. The plurality of side surfaces of the second groove (36B) may be symmetrical with respect to each other in the second direction and the third direction. For example, the bottom surface of the second groove (36B) may be square or circular, but is not limited thereto.

[0277] When both the first and second grooves of the holder (30) have the shape of the second groove (36B) illustrated in FIG. 16B, a manufacturing tolerance may occur with respect to the first and second grooves of the holder (30) and / or the front protrusions of the driving plate (61), and as a result, the front protrusions of the driving plate (61) may not be properly or stably coupled to the first and second grooves of the holder (30). In an embodiment, by making the shape of the first groove (36A) different from that of the second groove (36B), the coupling margin between the front protrusions (61B1, 61B2) of the driving plate (61) and the first and second grooves (36A, 36B) of the holder (30) can be increased. That is, even if the above-described manufacturing tolerance occurs, the front projections (61B1, 61B2) of the driving plate (61) can be suitably or stably coupled to the first and second grooves (36A, 36B) of the holder (30) by the first groove (36A), and stable OIS operation can be possible. However, in other embodiments, each of the first groove and the second groove of the holder (30) may have the same shape. For example, in other embodiments, each of the first groove and the second groove of the holder (30) may have the shape of the first groove (36A) or the second groove (36B) of FIG. 16B.

[0278] A protrusion or step may be formed around the second groove (36B) and the first groove (36A). The protrusion may be in the form of a protrusion protruding from the first surface (21a) of the rear outer surface (31b). A lubricant may be placed between the front projections (61B1, 61B2) and the first and second grooves (36A, 36B), and the protrusion formed around the first groove (36A) and the second groove (36B) may prevent the lubricant from overflowing. At least one engaging groove (105A, 105B) may be formed on the rear outer surface (31b) of the holder (30) for engaging with the magnetic support member (64). For example, the holder (30) may include a first coupling groove (105A) formed on the second surface (21b) of the rear outer surface (31b), and a second coupling groove (105B) formed on the third surface (21c). For example, at least one protrusion (2A) (or groove) may be formed on at least one of the side surface and the bottom surface of each of the first and second coupling grooves (105A, 105B). For example, at least one protrusion (2A) may correspond to at least one groove (7B) of the magnetic support member (64) or may be formed at a position corresponding to at least one groove (7B). Grooves (4A) for placing an adhesive may be formed on at least one of the side surface and the bottom surface of each of the first and second coupling grooves (105A, 105B). The bonding area between the adhesive and the magnetic support (64) can be increased by the grooves (4A), and the bonding force between the holder (30) and the magnetic support (64) can be improved. The holder (30) can include at least one stopper (not shown) formed on the rear outer surface (31b). For example, the stopper can be in the form of a protrusion or projection protruding from each of the second surface (21b) and the third surface (21c) of the rear outer surface (31b).

[0279] The second housing (50) can be disposed spaced apart from the first housing (610). The holder (30) can be disposed within the second housing (50). The second housing (50) can accommodate the holder (30) therein and expose the incident surface (8A) and the exit surface (8B) of the optical member (40) disposed in the holder (30). The second housing (50) can include a first opening (53A) (or first hole) for exposing the incident surface (8A) of the optical member (40) and a second opening (53B) (or second hole) for exposing the exit surface (8B) of the optical member (40).

[0280] The second housing (50) may include an upper portion (27A), a lower portion (27B), and a side portion positioned between the upper portion (27A) and the lower portion (27). For example, the side portion of the second housing (50) may include a plurality of side portions (28A to 28D). The upper portion (27A) and the lower portion (27B) may face each other in a second direction (e.g., in the X-axis direction) or may be positioned opposite to each other. For example, the second housing (50) may include a first side portion (28A), a second side portion (28B), a third side portion (28C), and a fourth side portion (28D).

[0281] For example, the first side (28A) of the second housing (50) may be arranged to face or be opposite the lens section (e.g., 620) of the first actuator (310). The first opening (53A) may be formed in the upper portion (27A), and the second opening (53B) may be formed in the first side (28A).

[0282] The second side (28B) may face the first side (28A) in the first direction or may be positioned opposite the first side (28A). The third side (28C) and the fourth side (28D) may be positioned between the first side (28A) and the second side (28D) and may face or be positioned opposite to each other in the third direction. For example, the third side (28C) may connect one end of the first side (28A) and one end of the second side (28B), and the fourth side (28D) may connect the other end of the first side (28A) and the other end of the second side (28B).

[0283] For example, the second housing (50) may include a first hole (54A) formed in the third side (28C) for mounting or arranging the first OIS coil unit (230A), a second hole (54B) formed in the fourth side for mounting or arranging the second OIS coil unit (230B), and a third hole (54C) formed in the lower portion (27B) for mounting or arranging the third OIS coil unit (230C). For example, each of the first to third holes (54A to 54C) is in the form of a through hole, but is not limited thereto, and may be in the form of a groove in other embodiments. In addition, a groove (56) (or a through hole) for mounting or arranging the driver IC (260) may be formed in the third side (28C) (or the fourth side (28D)) of the second housing (50). For example, the home (56) can be formed spaced apart from the first hole (54A).

[0284] The second housing (50) may include at least one engaging protrusion (51) formed on at least one of the third side (28C) and the fourth side (28D). For example, the engaging protrusion (51) may protrude from the outer surface of each of the third side (28C) and the fourth side (28D). In addition, the second housing (50) may include at least one engaging protrusion (52A) formed on the first side (28A). For example, the engaging protrusion (52A) may protrude from the outer surface of the first side (28A). In addition, the second housing (50) may include at least one engaging protrusion (52B) formed on the lower portion (28B). For example, the engaging protrusion (52B) may be formed to protrude from the outer surface of the lower portion (28B).

[0285] A guide protrusion (59A, 59B) for guiding the first circuit board (250A) may be formed on at least one of the upper and lower portions of the third side portion (28C) of the second housing (50). In addition, a guide protrusion for guiding the second circuit board (250B) may be formed on at least one of the upper and lower portions of the fourth side portion (28D) of the second housing (50).

[0286] The second side (28B) of the second housing (50) may include at least two grooves (58A, 58B) corresponding to at least two rear protrusions (61C1, 61C2) of the drive plate (61). For example, the at least two grooves (58A, 58B) of the second housing (50) may be arranged spaced apart in the second direction. A protrusion or step may also be formed around the at least two grooves (58A, 58B), and a lubricant may be arranged between the rear protrusions (61C1, 61C2) and the grooves (58A, 58B), and the description of the protrusion of the holder (30) may be applied or mutatis mutandis. In another embodiment, the at least two grooves (58A, 58B) may be arranged spaced apart in the third direction.

[0287] For example, the second housing (50) may include a protrusion (57) that protrudes from the inner surface of the second side (28B) toward the first side (28A), and the protrusion (57) of the second housing (50) may be formed with a first groove (58A) and a second groove (58B) that correspond to, oppose, or overlap the rear protrusions (61C1, 61C2) of the driving plate (61). In another embodiment, the second housing (50) may not include the protrusion (57), and the first groove (58A) and the second groove (58B) may be formed on the second side (28B) (e.g., the inner surface) of the second housing (50).

[0288] For example, the protrusion (57) may include a first portion (57A) protruding from the inner surface of the second side (28B) and a second portion (57B) connecting the first portion (57A) and the lower portion (27B) of the second housing (50). The first groove (58A) and the second groove (58B) of the second housing (50) may be formed on the inner surface (or front surface) of the second portion (57B) of the protrusion (57). In addition, a groove (44A) for placing or settling a second magnetic body (63) may be formed on the rear surface of the protrusion (57). The description of the shapes of the first and second grooves (36A, 36B) of the holder (30) may be applied or mutatis mutandis to the first and second grooves (58A, 58B) of the second housing (50).

[0289] In an embodiment, by making the shape of the second groove (58B) of the second housing (50) different from the shape of the first groove (58A), the coupling margin between the rear protrusions (61C1, 61C2) of the driving plate (61) and the first and second grooves (58A, 58B) of the second housing (50) can be increased. That is, even if a manufacturing tolerance occurs between the rear protrusions of the driving plate (61) and the first and second grooves of the first housing, the rear protrusions (61C1, 61C2) of the driving plate (61) can be suitably or stably coupled to the first and second grooves (58A, 58B) of the second housing (50) by the second groove (58B), thereby enabling stable OIS operation. In another embodiment, the shapes of the first and second grooves (36A, 36B) may be the same.

[0290] In Fig. 19b, when the second housing (50) is viewed from the front, the first groove (58A) is located on the upper side and the second groove (58B) is located on the lower side, but in other embodiments, the first groove (58A) may be located on the lower side and the second groove (58B) may be located on the upper side.

[0291] For example, an opening (55) for arranging a magnetic support member (64) may be formed in the second side (28B) of the second housing (50). For example, the opening (55) may be in the form of a through hole penetrating the second side (28B). For example, at least one through hole may be formed in the second side (28B) of the second housing (50). For example, a first through hole (55A) and a second through hole (55B) may be formed in the second side (28B) of the second housing (50). As illustrated in FIG. 19c, when viewed from the rear of the second housing (50), the first through hole (55A) may be located on one side (e.g., the left side) of the protrusion (57) of the second housing (50), and the second through hole (55B) may be located on the other side (e.g., the rear side) of the protrusion (57). A part of the magnetic support member (64) may pass through the first through hole (55A) of the second housing (50), and another part of the magnetic support member (64) may pass through the second through hole (55B) of the second housing (50).

[0292] Next, the support (60) will be described.

[0293] The support member (60) may be disposed between the holder (30) and the second housing (50). The support member (60) may support the holder (30) with respect to the second housing (50). The support member (60) may include a driving plate (61) disposed between the holder (30) and the second housing (50). The driving plate (61) may be alternatively expressed as a “mover,” a “tilting guide,” a “mover plate,” a “driving plate,” a “plate,” a “moving plate,” or a “support plate.”

[0294] The driving plate (61) may be disposed between the holder (30) and the second housing (50). For example, the driving plate (61) may be disposed between the second side of the holder (30) and the second housing (50). For example, the driving plate (61) may be disposed between the second side of the holder (30) and the second side (28B) of the second housing (50).

[0295] The drive plate (61) may include at least two front protrusions (61B1, 61B2) coupled with the holder (30) and at least two rear protrusions (61C1, 61C2) coupled with the second housing (50). For example, the at least two front protrusions (61B1, 61B2) may be arranged spaced apart in a third direction. Each of the front protrusions (61B1, 61B2) may be arranged in a corresponding one of the first and second grooves (36A, 36B) of the holder (30). In another embodiment, the front protrusions may be arranged spaced apart in the second direction.

[0296] For example, at least two rear protrusions (61C1, 61C2) may be arranged spaced apart in a second direction (e.g., in the Y-axis direction). Each of the rear protrusions (61C1, 61C2) may be arranged in a corresponding one of the first and second grooves (58A, 58B) of the second housing (50). In another embodiment, the rear protrusions may be arranged spaced apart in a third direction.

[0297] For example, the drive plate (61) may include a body (61A) disposed within a groove (106) of the holder (30), front protrusions (61B1, 61B2) protruding from the front of the body (61A), and rear protrusions (61C1, 61C2) protruding from the rear of the body (61A). For example, the front protrusions (61B1, 61B2) and the rear protrusions (61C1, 61C2) may protrude in opposite directions.

[0298] For example, each of the front protrusions (61B1, 61B2) may have a curved shape, a hemispherical shape, a dome shape, or a polyhedral shape, but is not limited thereto. Also, for example, each of the rear protrusions (61C1, 61C2) may have a curved shape, a hemispherical shape, a dome shape, or a polyhedral shape, but is not limited thereto.

[0299] In another embodiment, instead of the front projections, the front surface of the drive plate may have front grooves formed, and instead of the first and second grooves (36A, 36B), the holder may have projections formed for engaging with the front grooves of the drive plate. Also, in another embodiment, instead of the rear projections, the rear surface of the drive plate may have rear grooves formed, and instead of the first and second holes (58A, 58B), the first housing may have projections formed for engaging with the rear grooves of the drive plate.

[0300] For example, the driving plate (61) may be made of an injection-molded material such as plastic or resin. In another embodiment, the driving plate (61) may be made of a metal, for example, SUS material. In addition, the driving plate (61) may be a non-magnetic material. In another embodiment, the driving plate may be a magnetic material.

[0301] The support (60) may include a first magnetic body (62) placed or coupled to the holder (30), and a second magnetic body (63) placed or coupled to the second housing (50).

[0302] For example, the support (60) may include a magnetic support (64) on which a first magnetic body (62) is arranged and which is coupled with a holder (30). The magnetic support (64) may be arranged to be spaced apart from the driving plate (61), and a portion of the magnetic support (64) may be coupled with the holder (30).

[0303] The magnetic support member (64) can be coupled to the holder (30) by passing through at least a portion of the second housing (50). The magnetic support member (64) may also be alternatively expressed as a “support member,” a “mover rigid,” or a “coupling member.” The magnetic support member (64) can be coupled to the holder (30) by extending from the body (93) and passing through the second housing (50).

[0304] For example, a portion of the magnetic support (64) may pass through the second housing (50) and be coupled to the second side of the holder (30). For example, a portion of the magnetic support (64) may pass through the second housing (50) and be coupled to the rear outer surface (31b) of the second side of the holder (30).

[0305] For example, the magnetic support member (64) may include a body (93) in which a first magnetic body (62) is arranged, a first extension member (94a) extending from one side of the body (93) and passing through a first through-hole (55A) of a second housing (50) to be coupled to a first coupling groove (105A) of a holder (30), and a second extension member (94b) extending from the other side of the body (93) and passing through a second through-hole (55B) of a second housing (50) to be coupled to a second coupling groove (105B) of the holder (30). For example, the first extension member (94a) and the second extension member (94b) may be symmetrical left and right with respect to the body (93).

[0306] Also, for example, the first extension portion (94a) may be bent from one side (or one end) of the body (93), and the second extension portion (94b) may be bent from the other side (or the other end) of the body (93). For example, the first extension portion (94a) may include a portion that is bent at least once from one side (or one end) of the body (93). For example, the second extension portion (94b) may include a portion that is bent at least once from the other side (or the other end) of the body (93). For example, the extension portions (94a, 94b) may be bent in a direction toward the holder (30) or the optical member (40) with respect to the body (93). For example, the first extension portion (94a) and the second extension portion (94b) each include three bent portions, but in other embodiments, they may include one or two or more bent portions.

[0307] Referring to Fig. 15, for example, a groove (64a) may be formed on the front surface of the body (93) of the magnetic support member (64) to allow the first magnetic body (62) to be seated or placed. For example, the first magnetic body (62) may be coupled to the groove (64a) of the magnetic support member (64) by an adhesive. In addition, for example, the extensions (94a, 94b) of the magnetic support member (64) may be coupled to the coupling grooves (105A, 105B) of the holder (30) by an adhesive.

[0308] Referring to FIG. 19c, the second magnetic body (63) may be disposed on the second side (28B) of the second housing (50). For example, the second magnetic body (63) may be disposed on the protrusion (57) of the second housing (50). For example, the second magnetic body (63) may be disposed in the groove (44A) of the protrusion (57) of the second housing (50). For example, the second magnetic body (63) may be coupled to the groove (44a) of the second housing (50) by an adhesive. The magnetic body support (64) is coupled to the holder (30), but may also be expressed as a part of the holder (30). In another embodiment, the magnetic body support (64) may be expressed as an extension extending from the holder (30). In another embodiment, the magnetic body support (64) may be formed integrally with the holder (30).

[0309] The first magnetic body (62) and the second magnetic body (63) may be arranged to face each other or overlap each other in the first direction. The second magnetic body (63) may be arranged between the first magnetic body (62) and the driving plate (61). In the embodiment, the driving plate (61) is not positioned between the first magnetic body (62) and the second magnetic body (63), and since both the first magnetic body (62) and the second magnetic body (64) are arranged on one side of the driving plate (61) with respect to the driving plate (61), the separation distance between the first magnetic body (62) and the second magnetic body (63) can be reduced, thereby increasing the magnetic force (e.g., repulsive force) between the first magnetic body (62) and the second magnetic body (63).

[0310] The driving plate (61) can be pressed against the holder (30) and / or the second housing (50) by the repulsive force between the first and second magnetic bodies (62, 63), and can be brought into close contact with the holder (30) and / or the second housing (50). In the embodiment, since the magnetic force (e.g., repulsive force) between the first magnetic body (62) and the second magnetic body (63) is large, the driving plate (61) can stably support the holder (30), and thus, a stable OIS operation can be performed.

[0311] Referring to FIG. 22a, the length of the first magnetic body (62) in the second direction may be greater than the length of the second magnetic body (63) in the second direction. Also, referring to FIG. 13b, the length of the first magnetic body (62) in the third direction may be greater than the length of the second magnetic body (63) in the third direction. In another embodiment, the length of the first magnetic body (62) in the second direction may be equal to or less than the length of the second magnetic body (63) in the second direction, and the length of the first magnetic body (62) in the third direction may be equal to or less than the length of the second magnetic body (63) in the third direction. For example, the area of ​​the first surface of the first magnetic body (62) facing the second magnetic body (63) may be greater than the area of ​​the first surface of the second magnetic body (63) facing the first magnetic body (62). In other embodiments, the area of ​​the first face of the first magnetic body may be equal to or smaller than the area of ​​the first face of the second magnetic body.

[0312] A repulsive force may be applied between the first magnetic body (62) and the second magnetic body (63). For example, the first magnetic body (62) may include a first magnet. For example, the second magnetic body (63) may include a second magnet that exerts a repulsive force with the first magnet. For example, each of the first magnetic body (62) and the second magnetic body (63) may be a magnet including a north pole and a south pole.

[0313] Also, for example, the first magnetic body (62) may further include a first yoke (not shown) corresponding to the first magnet and disposed within a groove (64a). For example, the second magnetic body (63) may further include a second yoke (not shown) corresponding to the second magnet and disposed within a groove (44A) of the second housing (50), and the first yoke and the second yoke may increase a magnetic force (e.g., a repulsive force) acting between the first magnetic body (62) and the second magnetic body (63). For example, the facing surfaces of the first magnetic body (62) and the second magnetic body (63) may have the same polarity (N pole or S pole).

[0314] In another embodiment, the first magnetic body may be positioned opposite the second magnetic body with respect to the driving plate (61), and an attractive force may be applied between the first magnetic body and the second magnetic body. In another embodiment, the driving plate (61) may be pressed against the holder (30) and / or the second housing (50) by the attractive force between the first magnetic body and the second magnetic body, and may be brought into close contact with the holder (30) and / or the second housing (50). In this case, the facing surfaces of the first magnetic body and the second magnetic body may have opposite polarities.

[0315] Next, the second driving unit (70) will be described.

[0316] The second driving unit (70) tilts the holder (30) in the second direction or the third direction or rotates it by a preset angle. The second driving unit (70) may include an OIS magnet (31) and an OIS coil (230). The OIS magnet may be replaced with a “magnet” or a “magnet unit”, and the OIS coil may be replaced with a “coil” or a “coil unit”. In addition, the second driving unit (70) may include an OIS position sensor unit (240) and a substrate unit (250).

[0317] The OIS magnet (31) may be placed in the holder (30). For example, the OIS magnet (31) may include first OIS magnets (31A, 31B) and second OIS magnets (32). For example, the first OIS magnet may include a first magnet unit (31A) placed on a third side (31c) of the holder (30) and a second magnet unit (31B) placed on a fourth side (31d) of the holder (30). For example, the first magnet unit (31A) may face or overlap the second magnet unit (31B) in the third direction. For example, the first magnet unit (31A) may be placed in the first mounting groove (16A) of the third side (31c) of the holder (30), and the second magnet unit (31B) may be placed in the first mounting groove (16A) of the fourth side (31d) of the holder (30). The second OIS magnet may include a third magnet unit (32) placed on the lower surface (17) of the holder (30). The third magnet unit (32) may be placed in the second mounting groove (16B) of the holder (30).

[0318] Each of the first to third magnet units (31A, 31B, 32) may be a unipolar magnet or a bipolar magnet having one N pole and one S pole, but in another embodiment may be a bipolar magnet or a quadrupolar magnet having two N poles and two S poles. In another embodiment, at least one of the first to third magnet units (31A, 31B, 32) may be a unipolar magnet or a bipolar magnet, and the rest may be bipolar magnets or a quadrupolar magnet.

[0319] The OIS coil (230) may be disposed in the second housing (50). For example, the OIS coil may be disposed corresponding to or opposite the OIS magnet (31). For example, the OIS coil (230) may include a first OIS coil (230A, 230B) corresponding to, opposite to, or overlapping the first OIS magnet (31A, 31B) in a third direction and a second OIS coil (230C) corresponding to, opposite to, or overlapping the second OIS magnet (32) in a second direction. For example, the first OIS coil may include a first OIS coil unit (230A) corresponding to, opposite to, or overlapping the first magnet unit (31A) in a third direction and a second OIS coil unit (230B) corresponding to, opposite to, or overlapping the second magnet unit (31B) in the third direction. For example, the second OIS coil may include a third OIS coil unit (230C) corresponding to, opposite to, or overlapping with the third magnet unit (32) in the second direction. For example, the first OIS coil unit (230A) may be disposed in the third side (28C) of the second housing (50) (e.g., the first hole (34A)), the second OIS coil unit (230B) may be disposed in the fourth side (28D) of the second housing (50) (e.g., the second hole (54B)), and the third OIS coil unit (230C) may be disposed in the lower portion (28B) of the second housing (50) (e.g., the third hole (54C)).

[0320] For example, the first OIS coil unit (230A) may have a closed curve or ring shape including a hollow or hole. The first OIS coil unit (230A) may be implemented in a coil ring shape that is wound clockwise or counterclockwise with respect to a third axis parallel to the third direction. The second OIS coil unit (230B) may have a closed curve or ring shape including a hollow or hole. The second OIS coil unit (230B) may be implemented in a coil ring shape that is wound clockwise or counterclockwise with respect to a third axis parallel to the third direction. The third OIS coil unit (230C) may have a closed curve or ring shape including a hollow or hole. The third OIS coil unit (230C) may be implemented in a coil ring shape that is wound clockwise or counterclockwise with respect to a second axis parallel to the second direction.

[0321] Referring to FIG. 21, a first electromagnetic force (F21, F22, F31, F32) can be generated by the interaction between the first OIS magnet (31A, 31B) and the first OIS coil (230A, 230B). That is, the first electromagnetic force can be generated by the interaction between the first magnet unit (31A) and the first OIS coil unit (230A) and the interaction between the second magnet unit (31B) and the second OIS coil unit (230B). For example, a first-first electromagnetic force (F22, F32) may be generated by the interaction between the first magnet unit (31A) and the first OIS coil unit (230A), a first-second electromagnetic force (F21, F31) may be generated by the interaction between the second magnet unit (31B) and the second OIS coil unit (230B), and the first electromagnetic force may include the first-first electromagnetic force (F22, F32) and the first-second electromagnetic force (F21, F31). In addition, a second electromagnetic force (F1, F2) may be generated by the interaction between the second OIS magnet (32) and the third OIS coil unit (230C). The OIS moving part (e.g., holder (30)) can be tilted along a second axis (e.g., X-axis) by the first electromagnetic force (F21, F22, F31, F32). Here, the second axis (X-axis) tilting means that the OIS moving part is tilted based on the second axis (X-axis) or the OIS moving part is rotated by a preset angle with the second axis (X-axis) as the rotation axis.

[0322] The OIS moving unit can be tilted about a third axis (e.g., Y-axis) by the second electromagnetic force (F1, F2). Here, the third-axis (Y-axis) tilting means that the OIS moving unit is tilted with respect to the third axis or that the OIS moving unit rotates by a preset angle with the third axis as the rotation axis.

By this arrangement, the electromagnetic force is applied evenly to the third side (31c) and the fourth side (31d) of the holder (30), so that the X-axis tilt can be performed accurately and precisely.

[0324] In another embodiment, the OIS moving part (e.g., holder (30)) may be tilted about a third axis (e.g., Y axis) by an electromagnetic force due to an interaction between the first OIS magnet (31A, 31B) and the first OIS coil (230A, 230B), and the OIS moving part (e.g., holder (30)) may be tilted about a second axis (e.g., X axis) by an electromagnetic force due to an interaction between the second OIS magnet (32) and the third OIS coil unit (230C).

[0333] The camera device (200) may further include a gyro sensor (82) disposed on the substrate (250). For example, the gyro sensor (82) may be a two-axis, three-axis, or five-axis gyro sensor or an angular velocity sensor.

[0334] The camera device (200) may further include a driver IC (260) disposed on the substrate (250). For example, the driver IC (260) may be disposed or mounted on the first circuit substrate (250A). For example, the driver IC (260) may be disposed on the second housing (50). For example, the second driver (260) may be arranged or mounted on the first surface of the first circuit board (250A) of the second housing (50). The driver IC (260) may be electrically connected to the first OIS coil (230A, 230B) and the second OIS coil (230C). In addition, the driver IC (260) may be electrically connected to the first OIS position sensor (240A, 240B) and the second OIS position sensor (240C). For example, the driver IC (260) may provide a driving signal to each of the first OIS position sensor (240A, 240B) and the second OIS position sensor (240C), and may receive a first output signal of the first OIS position sensor (240A, 240B) and a second output signal of the second OIS position sensor (240C).

[0335] Also, for example, the driver IC (260) can supply a first driving signal (e.g., driving current or driving voltage) to the first OIS coil (230A, 230B) and feedback-control the first driving signal using the first output signal of the first OIS position sensor (240A, 240B). Also, for example, the driver IC (260) can supply a second driving signal (e.g., driving current or driving voltage) to the second OIS coil (230C) and feedback-control the second driving signal using the second output signal of the second OIS position sensor (240C). For example, the second driver (260) can be expressed as an “OIS driver”, a “second driver IC”, or an “OIS control unit”.

[0336] In addition, the camera device (200) may further include a cover plate (50A) disposed on the second side (28B) of the second housing (50) and covering the opening (55) of the second housing (50). The cover plate (50A) may be coupled or attached to the outer surface of the second side (28B) of the second housing (50) and may prevent foreign substances from entering the second housing (50). A groove (109) may be formed on the outer surface of the second side (28B) of the second housing (50) for arranging or settling the cover plate (50A). In addition, the cover plate (50A) may include a coupling protrusion (51-1) protruding in the second direction or the third direction, and the second housing (50) may include a coupling groove (51-2) for coupling with the coupling protrusion (51-1) of the cover plate (50A). The cover plate (50A) may be formed of a non-magnetic material. For example, the cover plate (50A) may be formed of an injection molded material such as resin or plastic, similar to the second housing (50). In another embodiment, the cover plate (50A) may include a magnetic body or may be formed of a magnetic material. For example, the cover plate (50A) may be a magnetic body plate. When the cover plate (50A) is a magnetic body plate, the magnetic flux of the first magnetic body (62) leaking to the rear of the first magnetic body (62) can be reduced, the magnetic flux generated from the first magnetic body (62) can be concentrated to the second magnetic body (63), and the repulsive force between the first and second magnetic bodies (62, 63) can be increased. This prevents sagging of the drive plate (61), enables the drive plate (61) to stably support the holder (30), enables stable OIS operation, and ensures reliability of OIS operation.

[0337] The OIS position sensor unit (240) detects the position of the OIS moving unit in the second direction and / or the third direction according to the movement of the OIS moving unit, and outputs an output signal according to the detection result. The OIS position sensor unit (240) may be expressed as a “second position sensor unit.”

[0338] The OIS position sensor unit (240) may include a plurality of position sensors. For example, the OIS position sensor unit (240) may include a first OIS position sensor (240A, 240B) and a second OIS position sensor (240C). At least a portion of the first OIS position sensors (240A, 240B) may correspond to, face, or overlap the first OIS magnet (31) in a third direction and may detect the strength of the magnetic field of the first OIS magnet (31). For example, the first OIS position sensor may include a first sensor (240A) arranged or mounted on a first circuit board (250A) and a second sensor (240B) arranged or mounted on a first substrate (250-1) of a second circuit board (240B). For example, the first sensor (240A) may be placed within a hollow (or hole) of the first OIS coil unit (230A), and the second sensor (240B) may be placed within a hollow (or hole) of the second OIS coil unit (230B).

[0339] For example, the first sensor (240A) and the second sensor (240B) may each be a Hall sensor including first and second input terminals and first and second output terminals. The first and second input terminals of the first sensor (240A) and the first and second input terminals of the second sensor (240B) may be connected in parallel, and the driver IC (260) may supply a driving signal or power to the parallel-connected first and second input terminals of the first and second sensors (240A, 240B). The first and second output terminals of the first sensor (240A) and the first and second output terminals of the second sensor (240B) may be connected in series, and a first output signal may be output from both ends of the serially connected first and second output terminals of the first and second sensors (240A, 240B), and the first output signal may be transmitted to the driver IC (260).

[0340] At least a portion of the second OIS position sensor (240C) may correspond to, face, or overlap with the second OIS magnet (32) in the second direction and may detect the strength of the magnetic field of the second OIS magnet (32). For example, the second OIS position sensor (240C) may include a third sensor (240C1) and a fourth sensor (240C2) arranged or mounted on the third circuit board (250C). The third sensor (240C1) and the fourth sensor (240C2) may face or overlap with the third OIS magnet (32) in the second direction. For example, the third sensor (240C1) and the fourth sensor (240C2) may be arranged to be spaced apart from each other in the third direction. For example, the third sensor (240C1) and the fourth sensor (240C) may be placed within a hollow space (or hole) of the third OIS coil unit (230C).

[0341] For example, the third sensor (240C1) and the fourth sensor (240C2) may each be a Hall sensor including first and second input terminals and first and second output terminals. The first and second input terminals of the third sensor (240C1) and the first and second input terminals of the fourth sensor (240B) may be connected in parallel, and the driver IC (260) may supply a driving signal or power to the first and second input terminals of the third and fourth sensors (240C1, 240C2) that are connected in parallel. The first and second output terminals of the third sensor (240C1) and the first and second output terminals of the fourth sensor (240C2) can be connected in series, and a second output signal can be output from both ends of the series-connected first and second output terminals of the third and fourth sensors (240C1, 240C2), and the second output signal can be transmitted to the driver IC (260).

[0342] In another embodiment, the output terminals of each of the first and second sensors may be unconnected and independent of each other, and may output independent output signals. In addition, the output terminals of each of the third and fourth sensors may be unconnected and independent of each other, and may output independent output signals.

[0343] In another embodiment, the first OIS position sensor may include a single position sensor (e.g., a Hall sensor or a driver IC including a Hall sensor). The second OIS position sensor may include a single position sensor (e.g., a Hall sensor or a driver IC including a Hall sensor).

[0344] Referring to FIG. 23, the camera device (200) may include a first driving unit (630), a second driving unit (70), a first position sensor unit (170), a second position sensor unit (240), a storage unit (180), an image sensing unit (600), and a control unit (810).

[0345] The first driving unit (630) receives a first driving signal, applies the received first driving signal to the first coil (120A), and moves the lens assembly (622) in the first direction by the interaction between the first coil (120A) and the first magnet (130A). In addition, the first driving unit (630) receives a second driving signal, applies the received second driving signal to the second coil (120B), and moves the lens assembly (624) in the first direction by the interaction between the second coil (120B) and the second magnet (130B). The second driving unit (70) receives the first OIS driving signal, applies the received first OIS driving signal to the first OIS coil (230A, 230B), and rotates the OIS moving unit (e.g., holder (30)) by a preset angle about the second axis (e.g., X-axis) as the rotation axis through interaction between the first OIS coil (230A, 230B) and the first OIS magnet (31A, 31B). In addition, the second driving unit (70) receives the second OIS driving signal, applies the received second OIS driving signal to the second OIS coil (230C), and rotates the OIS moving unit (e.g., holder (30)) by a preset angle about the third axis (e.g., Y-axis) as the rotation axis through interaction between the second OIS coil (230C) and the second OIS magnet (32).

[0346] The second driving unit (70) can move on a plane (e.g., XY plane) perpendicular to the first axis (optical axis or Z axis) in which the path of light incident on the optical member (40) is caused by the movement of the holder (30) coupled with the optical member (40), thereby moving the image formed on the image sensor (540) in the X-axis direction and / or the Y-axis direction. That is, by controlling the movement of the holder (30), the embodiment can correct blurring of an image or shaking of a video caused by shaking of a camera device when taking an image or shooting a video due to the user's hand shaking.

[0347] The first position sensor unit (170) receives a first driving signal and supplies the received first driving signal (DI1) to the first sensor (71A) and the second sensor (71B). The first position sensor unit (170) receives a second driving signal and supplies the received second driving signal to the third sensor (72A) and the fourth sensor (72B). The first position sensor unit (170) detects the displacement of the lens assembly (622) and outputs a first output signal according to the detection result. In addition, the first position sensor unit (170) detects the displacement of the lens assembly (624) and outputs a second output signal according to the detection result.

[0348] The second position sensor unit (240) supplies a driving signal to each of the first sensor (240A), the second sensor (240B), and the second OIS position sensor (240C) of the first OIS position sensor. The first OIS position sensors (240A, 240B) can detect displacement of the holder (30) in the third axis direction and output an output signal according to the detected result. The second OIS position sensor (240C) can detect displacement of the holder (30) in the second axis direction and output an output signal according to the detected result.

[0349] The storage unit (180) stores data necessary to operate the camera device (200). The storage unit (180) may also be expressed as a "memory." For example, the storage unit (180) may store information on the zoom position and focus position according to the distance from the subject.

[0350] For example, the storage unit (180) may store a first reference code value (or data) regarding a first output signal of the first position sensor (71) corresponding to the movement range (or stroke range or displacement) of the lens assembly (622). In addition, the storage unit (180) may store a second reference code value (or data) regarding a second output signal of the second position sensor (72) corresponding to the movement range (or stroke range or displacement) of the lens assembly (624). The first and second reference code values ​​may be values ​​stored in advance in the storage unit (180) through calibration.

[0351] The storage unit (180) may be a separate configuration from the control unit (810), but is not limited thereto, and in other embodiments, may be included in the control unit (810). For example, the storage unit (180) may be included in at least one of the driver IC (542) and the driver IC (260). For example, the focus of the camera device (200) may be accurately adjusted based on the target position of the lens assembly (622) and the target position of the lens assembly (624).

[0352] The image sensing unit (330) may include an image sensor (540) that converts light reflected from a subject into an electrical signal. For example, the image sensor (540) may include a light receiving unit that receives light and converts it into an electrical signal, and an analog-to-digital converter that converts the converted electrical signal into a digital signal. In addition, for example, the image sensor (540) may further include an image signal processor that performs signal processing on the digital signal.

[0353] The control unit (810) controls the overall operation of the camera device (200). For example, the control unit (200) may control the first position sensor unit (170) and the second position sensor unit (240) and drive the first driving unit (630) and the second driving unit (70) to provide an anti-shake function, an auto-focus function, and a magnification adjustment function. For example, the control unit (810) may include at least one of a driver IC (542) and a driver IC (260). For example, each of the driver IC (542) and the driver IC (260) may include at least one of an analog-to-digital converter, an amplifier, a PID controller, or a memory.

[0354] The driver IC (542) receives the output signal of the first position sensor unit (170), generates a first code value according to the result of analog-to-digital conversion of the received output signal, and controls a driving signal applied to the first coil (120) of the first driving unit (630) based on the result of comparing the generated first code value with the first target value. For example, the first target value may be a reference code value corresponding to a target zoom position of the lens assembly (622).

[0355] The driver IC (260) can receive an output signal of the first OIS position sensor (240A, 240B) of the second position sensor unit (240), generate a second code value according to a result of analog-to-digital conversion of the received output signal, and control a first driving signal applied to the first OIS coil (230A, 230B) of the second driving unit (70) based on a result of comparing the generated second code value with a second target value. In addition, the driver IC (260) can receive an output signal of the second OIS position sensor (240C) of the second position sensor unit (240), generate a third code value according to a result of analog-to-digital conversion of the received output signal, and control a second driving signal applied to the second OIS coil (230C) of the second driving unit (70) based on a result of comparing the generated third code value with a third target value. For example, the second target value may be a reference code value (or data) regarding the output of the first OIS position sensor (240A, 240B) corresponding to the target second-axis (X-axis) tilting position of the OIS moving unit of the second actuator (320). Also, for example, the third target value may be a reference code value (or data) regarding the output of the second OIS position sensor (240C) corresponding to the target third-axis (Y-axis) tilting position of the OIS moving unit of the second actuator (320). The reference code values ​​(or data) regarding the outputs of each of the first OIS position sensors (240A, 240B) and the second OIS position sensor (240C) may be preset through calibration and stored in the storage unit (180).

[0356] The temperature sensor (566) can output temperature information based on the result of measuring the temperature of the camera device (200). The temperature information of the temperature sensor (566) can be used for temperature compensation for the focusing operation of the lens assembly (624). For example, the storage unit (180) can store a compensation value corresponding to the temperature information. For example, since the lens assembly (622) responsible for zooming moves according to the magnification set by the user, temperature compensation for the lens assembly (624) responsible for auto-focusing can be performed in a state (or condition) where the position of the lens assembly (622) is fixed. In addition, for example, the control unit (810) can receive temperature information from the temperature sensor (566), obtain a compensation value for temperature compensation corresponding to the received temperature information, and control the driving signal of the second coil (120B) of the lens assembly (624) based on the obtained compensation value. Accordingly, in the embodiment, an accurate auto-focusing operation reflecting temperature compensation can be performed.

For example, the fixed portion may include at least one of a substrate portion (1250), a coil (1230), and a position sensor (1240).

[0364] The OIS moving unit may include an optical member (1040). The OIS moving unit may include a holder (1030) for accommodating the optical member (1040) and a configuration coupled with the holder (1030). For example, the OIS moving unit may further include a magnetic support member (1064). For example, the OIS moving unit may further include at least one of the magnets (1031, 1032, 1062). The actuator (1320) may further include a tilting guide member (1061) disposed between the fixed member and the OIS moving unit. The OIS moving unit may further include a yoke (1033).

[0365] The optical member (1040) can change the path of light so that light passing through the opening (1303) of the cover member (1300) is incident on the actuator (1310). The actuator (1320) can include an OIS driving unit that rotates the OIS moving unit (e.g., the optical member (1040)) by a preset angle around (or as the center) of a second axis (e.g., the X-axis) or a third axis (e.g., the Y-axis). For example, the OIS driving unit can include a coil (1230) and magnets (1031, 1032).

[0366] The optical member (1040) may include a reflector capable of changing the direction of light propagation. For example, the optical member (1040) may be a prism that reflects light. In another embodiment, the optical member (1040) may be a mirror. The optical member (1040) may be placed in the holder (1030). The optical member (1040) may change the optical path of incident light into an optical axis parallel to the central axis (Z-axis) or the first axis (Z-axis) of the lens units (1640, 1622, 1624), thereby changing the incident light into parallel light. At this time, the parallel light may pass through the lens units (1640), the lens units (1622), and the lens units (1624) to reach the image sensor (1540).

[0367] Referring to FIG. 28A, for example, the optical member (1040) may include an incident surface (1008A) and an exit surface (1008B), and may reflect light incident on the incident surface (1008A) and exit it on the exit surface (1008B). For example, the optical member (1040) may be a right-angled prism including an incident surface (1008A), a reflective surface (1008C), and an exit surface (1008B). Due to the change in the optical path by the optical member (1040), the thickness of the camera device (1200) in the direction perpendicular to the incident surface (1008A) of the optical member (1040) may be reduced, thereby reducing the thickness of the mobile device or terminal (200A) on which the camera device (1200) is mounted.

[0368] The holder (1030) may include a mounting portion (1104) for placing or mounting an optical member (1040). The mounting portion (1104) may be in the form of a groove and may have a mounting surface (1104a) (or mounting surface) for placing a reflective surface (1008C) of the optical member (1040). For example, the mounting surface (1104a) may be an inclined surface inclined with respect to the optical axis direction.

[0369] For example, an adhesive for attaching an optical member (1040) to a mounting surface (1104a) of a holder (1030) may be disposed, and at least one groove (1104b) for receiving the adhesive may be formed in the mounting surface (1104a). For example, the holder (1030) may include a first opening exposing an incident surface (1008A) of the optical member (1040) and a second opening exposing an exit surface (1008B) of the optical member (1040). For example, the first opening may be disposed on an upper side of the holder (1030), and the second opening may be disposed on a side of the holder (1030) facing a lens portion (e.g., 1640) of the actuator (1310). The emission surface (1008B) of the optical member (1040) mounted on the holder (1030) can be positioned to face the lens unit (1640) of the actuator (1310).

[0370] The holder (1030) may include at least one stopper (1038) disposed on an upper surface of the holder (1030). The holder (1030) may include at least one stopper (1039A) disposed on a side of the holder (1030). The holder (1030) may include at least one stopper (1041) disposed on a lower surface of the holder (1030). The tilt or rotation of the holder (1030) may be limited by the stoppers (1038, 1039A, 1041).

[0371] The holder (1030) may include a mounting groove (1014A, 1014B) for placing or settling a magnet (1031) and a mounting groove (1014C) for placing or settling a magnet (1032). For example, the mounting grooves (1014A, 1014B) may be formed on the outer surfaces of the sides (1048A, 1048B) of the holder (1030) that are positioned opposite each other. The mounting groove (1014C) may be formed on the lower portion of the holder (1030) or the lower surface of the holder (1030).

[0372] The holder (1030) may include at least one groove (1036: 1036A, 1036B) corresponding to at least one protrusion (1061B1, 1061B2) of the tilting guide portion (1061). For example, the grooves (1036A, 1036B) of the holder (1030) may be arranged to be spaced apart in a second direction (e.g., in the X-axis direction). The number of grooves of the holder (1030) may be the same as the number of protrusions of the tilting guide portion (1061). The grooves (1036A, 1036B) may have different shapes. In another embodiment, the grooves (1036A, 1036B) may have the same shape. In another embodiment, the grooves (1036A, 1036B) of the holder (1030) may be arranged spaced apart in a third direction (e.g., in the Y-axis direction).

[0373] The holder (1030) may include at least one protrusion (1037) protruding from a side (1048C) positioned between the sides (1048A, 1048B) of the holder (1030). The at least one protrusion (1037) may be coupled with a magnetic support (1064). The protrusion (1037) may protrude from an outer surface of the side (1048C) of the holder (1030). The protrusion (1037) may include a first protrusion (1037A) and a second protrusion (1037B) that are spaced apart from each other. In other embodiments, the number of protrusions (1037) may be one or three or more. Each of the protrusions (1037A, 1037B) may include at least one protrusion (1022) for coupling with the magnetic support (1064). The protrusion (1037) of the holder (1030) can pass through at least a portion of the housing (1050) and engage with the magnetic support (1064). For example, the protrusion (1037) of the holder (1030) can pass through the opening (1055) of the housing (1050) and engage with the magnetic support (1064).

[0374] In another embodiment, the magnetic support member may be coupled to the holder (1030) by passing through at least a portion of the housing (1050). In this case, the housing (1050) may include an opening for the magnetic support member to pass through. Additionally, the holder may be formed with a coupling groove for coupling the magnetic support member.

[0375] The housing (1050) can be placed within the cover member (1300). The holder (1030) can be placed within the housing (1050). The housing (1050) can accommodate the holder (1030) therein and expose the incident surface (1008A) and the exit surface (1008B) of the optical member (1040) placed in the holder (1030).

[0376] Referring to FIGS. 31A and 31B, the housing (1050) may include a first opening (1053A) (or first hole) for exposing the incident surface (1008A) of the optical member (1040) and a second opening (1053B) (or second hole) for exposing the exit surface (1008B) of the optical member (1040).

[0377] The housing (1050) may include an upper portion (1027A), a lower portion (1027B), and a side portion positioned between the upper portion (1027A) and the lower portion (1027B). For example, the housing (1050) may include a plurality of side portions (1028A to 1028D). The upper portion (1027A) and the lower portion (1027B) may face each other in a second direction (e.g., in the X-axis direction) or may be positioned opposite to each other. The side (1028A) of the housing (1050) may correspond to or be opposite to the side (1048A) of the holder (1030), the side (1028B) of the housing (1050) may correspond to or be opposite to the side (1048B) of the holder (1030), and the sides (1028A, 1028B) of the housing (1050) may be positioned on opposite sides. The side (1028C) of the housing (1050) may be positioned between the sides (1028A, 1028B) of the housing (1050) and may be positioned to be opposite or facing the lens portion (e.g., 1640) of the actuator (1310). The side portion (1028D) of the housing (1050) may be positioned between the sides (1028A, 1028B) of the housing (1050) and may be positioned opposite the side portion (1028C) of the housing (1050) in the optical axis direction. The first opening (1053A) may be formed in the upper portion (1027A) of the housing (1050), and the second opening (1053B) may be formed in the side portion (1028C) of the housing (1050). The side portion (1028D) of the housing (1050) may be formed separately from the sides (1028A, 1028B, 1028C) of the housing (1050) and may be assembled to the sides (1028A, 1028B) of the housing (1050). For example, one end of the side (1028D) of the housing (1050) can be coupled with one end of the side (1028A) of the housing (1050), and the other end of the side (1028D) of the housing (1050) can be coupled with one end of the side (1028B) of the housing (1050).

[0378] For example, the side portion (1028D) of the housing (1050) may be bonded to the sides (1028A, 1028B) of the housing (1050) by adhesive. In another embodiment, the sides (1028A, 1028B, 1028C, 1028D) of the housing (1050) may be formed integrally.

[0379] For example, the housing (1050) may include a first mounting portion (1054A) formed on a side (1028A) of the housing (1050) for mounting or arranging a first coil unit (1230A1) of the coil (1230), a second mounting portion (1054B) formed on a side (1028B) of the housing (1050) for mounting or arranging a second coil unit (1230A2) of the coil (1230), and a third mounting portion (1054C) formed on a lower portion (1027B) of the housing (1050) for mounting or arranging a third coil unit (1230B) of the coil (1230). Each of the mounting portions (1054A, 1054B, 1054C) is in the form of a through hole, but may be a groove in other embodiments.

[0380] The housing (1050) may include at least one engaging protrusion (1051) for engaging with the substrate portion (1250). The engaging protrusion (1051) may be positioned on at least one of the sides (1028A, 1028B) of the housing (1050).

[0381] The housing (1050) may include a mounting portion (1056) for placing or mounting the driver IC (1260). The mounting portion (1056) may be placed on one of the sides (1028A, 1028B) of the housing (1050). The mounting portion (1056) may be in the form of a groove or a through hole.

[0382] The housing (1050) may include at least one groove (1058A, 1058B) corresponding to at least one protrusion (1061C1, 1061C2) of the tilting guide portion (1061). The number of grooves (1058A, 1058B) of the housing (1050) may be the same as the number of protrusions (1061C1, 1061C2) of the tilting guide portion (1061). The grooves (1058A, 1058B) of the housing (1050) may face or overlap the protrusions (1061C1, 1061C2) of the tilting guide portion (1061). The grooves (1058A, 1058B) may be formed on the side (1028D) of the housing (1050) facing the tilting guide portion (1061). The grooves (1058A, 1058B) may be formed on the inner surface of the side (1028D) of the housing (1050).

[0383] For example, the housing (1050) may include grooves (1058A, 1058B) corresponding to the protrusions (1061C1, 1061C2) of the tilting guide portion (1061). The grooves (1058A, 1058B) of the housing (1050) may be arranged to be spaced apart in a third direction (e.g., in the Y-axis direction). The grooves (1058A, 1058B) may have different shapes. In another embodiment, the grooves (1058A, 1058B) may have the same shape. In another embodiment, the grooves (1058A, 1058B) of the housing (1050) may be arranged to be spaced apart in a second direction (e.g., in the X-axis direction).

[0384] The side portion (1028D) of the housing (1050) may be replaced with a “joint portion” or a “second member”, and the remaining portion of the housing (1050) excluding the side portion (1028D) may be replaced with a “body” or a “first member”.

[0385] The housing (1050) may include an opening (1055) in which at least a portion of the protrusion (1037) of the holder (1030) is disposed. At least a portion of the protrusion (1037) of the holder (1030) may pass through the opening (1055) of the housing (1050). The opening (1055) may be formed in a side portion (1028D) of the housing (1050). For example, the opening (1055) may be a through hole or hollow portion penetrating the side portion (1028D) of the housing (1050). In another embodiment, the opening (1055) may be an “escape portion” or “escape groove” to avoid spatial interference with the protrusion (1037) of the holder (1030).

[0386] The number of openings (1055) may be equal to the number of protrusions (1037). The housing (1050) may include a first opening (1055A) passing through a first protrusion (1037A) of the holder (1030) and a second opening (1055B) passing through a second protrusion (1037B) of the holder (1030).

[0387] The housing (1050) may include a groove (1078) for accommodating a magnetic support (1064) or for placing the magnetic support (1064). The groove (1078) may be formed in the side (1028D) of the housing (1050). The groove (1078) may be formed on an outer surface of the side (1028D) of the housing (1050). The groove (1078) may be recessed from the outer surface of the side (1028D) of the housing (1050). In other embodiments, the groove (1078) may not be formed. The outer surface of the side (1028D) of the housing (1050) may be an opposite surface to the inner surface of the side (1028D) of the housing (1050).

[0388] The housing (1050) may include a groove (1044A) for arranging a magnetic body (1063). The groove (1044A) may be formed on a side (1028D) of the housing (1050). For example, the groove (1044A) may be formed on a bottom surface of a groove (1078) formed on the side (1028D) of the housing (1050). Also, for example, the first opening (1055A) and the second opening (1055B) of the housing (1050) may be formed on a bottom surface of the groove (1078). For example, the groove (1044A) may be arranged between the first opening (1055A) and the second opening (1055B).

[0389] The tilting guide unit (1061) can be positioned between the fixed unit and the OIS moving unit and can support the OIS moving unit with respect to the fixed unit. The tilting guide unit (1061) can also be expressed as a “mover”, a “driving plate”, a “tilting guide”, a “mover plate”, a “driving plate”, a “plate”, a “moving plate”, or a “support plate”.

[0390] The tilting guide part (1061) may be disposed between the holder (1030) and the housing (1050). For example, the tilting guide part (1061) may be disposed between the side (1048C) of the holder (1030) and the side (1028D) of the housing (1050). The tilting guide part (1061) may include protrusions (1061B1, 1061B2) that contact the holder (1030) and protrusions (1061C1, 1061C2) that contact the housing (1050). The protrusions (1061B1, 1061B2) may be alternatively expressed as “front protrusions” or “first protrusions”, and the protrusions (1061C1, 1061C2) may be alternatively expressed as “rear protrusions” or “second protrusions”. The number of each of the anterior protrusions and the posterior protrusions may be 1 or more. In FIGS. 30a and 30b, the number of each of the anterior protrusions and the posterior protrusions may be 2.

[0391] The front protrusions (1061B1, 1061B2) may be arranged spaced apart from each other. The rear protrusions (1061C1, 1061C2) may be arranged spaced apart from each other. The direction in which the front protrusions (1061B1, 1061B2) are arranged and the direction in which the rear protrusions (1061C1, 1061C2) are arranged may intersect each other. For example, the front protrusions (1061B1, 1061B2) may be arranged in a second direction (X-axis direction), and the rear protrusions (1061C1, 1061C2) may be arranged in a third direction (Y-axis direction). In another embodiment, the front protrusions (1061B1, 1061B2) may be arranged in a third direction (Y-axis direction), and the rear protrusions (1061C1, 1061C2) may be arranged in a second direction (X-axis direction).

[0392] At least a portion of each of the front protrusions (1061B1, 1061B2) may be positioned in a corresponding one of the grooves (1036A, 1036B) of the holder (1030). At least a portion of each of the rear protrusions (1061C1, 1061C2) may be positioned in a corresponding one of the grooves (1058A, 1058B) of the housing (1050).

[0393] The tilting guide portion (1061) may include a body (1061A), front protrusions (1061B1, 1061B2) protruding from a first surface of the body (1061A), and rear protrusions (61C1, 61C2) protruding from a second surface of the body (1061A). For example, the front protrusions (61B1, 61B2) and the rear protrusions (1061C1, 1061C2) may protrude in opposite directions. The second surface of the body (1061A) may be an opposite surface of the first surface of the body (1061A).

[0394] For example, each of the front protrusions (1061B1, 1061B2) may have a curved shape, a hemispherical shape, a dome shape, or a polyhedral shape. Additionally, each of the rear protrusions (1061C1, 1061C2) may have a curved shape, a hemispherical shape, a dome shape, or a polyhedral shape.

[0395] In another embodiment, instead of the front protrusions, the first surface of the tilting guide portion may have front grooves formed thereon, and instead of the grooves (1036A, 1036B), the holder (1030) may have protrusions formed thereon for engaging with the front grooves of the tilting guide portion. Also, in another embodiment, instead of the rear protrusions, the second surface of the tilting guide portion may have rear grooves formed thereon, and instead of the grooves (1058A, 1058B), the housing (1050) may have protrusions formed thereon for engaging with the rear grooves of the tilting guide portion.

[0396] In another embodiment, instead of the front protrusions, the first surface of the tilting guide portion may have front grooves formed, instead of the rear protrusions, the second surface of the tilting guide portion may have rear grooves formed, and the camera device (1200) may include front ball members arranged between the grooves (1036A, 1036B) of the holder (1030) and the front grooves of the tilting guide portion, and rear ball members arranged between the grooves (1058A, 1058B) of the housing (1050) and the rear grooves of the tilting guide portion.

[0397] The tilting guide part (1061) may be made of an injection-molded material such as plastic or resin. In another embodiment, the tilting guide part (1061) may be made of a metal, for example, SUS material. In addition, the tilting guide part (1061) may be a non-magnetic material. In another embodiment, the tilting guide part may be a magnetic material.

[0398] Referring to FIG. 30A, grooves (1006A, 1006B) corresponding to, opposite to, or overlapping the front protrusions may be formed on the second surface of the tilting guide portion (1061). Referring to FIG. 30B, grooves (1006C, 1006D) corresponding to, opposite to, or overlapping the rear protrusions may be formed on the first surface of the tilting guide portion (1061). The grooves (1006A to 1006D) are formed to facilitate the injection molding process for the tilting guide portion (1061).

[0399] The camera device (1200) may include a magnetic body (1063) disposed in a fixed portion and a magnetic body (1062) disposed in an OIS moving portion. The magnetic body (1062) may be coupled to the OIS moving portion, and the magnetic body (1063) may be coupled to the fixed portion. For example, the magnetic body (1062) may be coupled to a holder (1030), and the magnetic body (1063) may be coupled to a housing (1050). The magnetic body (1062) may be disposed in the holder (1030), and the magnetic body (1063) may be disposed in the housing (1050).

[0400] The camera device (1200) may include a magnetic support (1064) on which a magnetic body (1062) is arranged and coupled with a holder (1030). The magnetic body (1062) may be coupled with the magnetic support (1064). The magnetic support (1064) may be arranged spaced apart from the tilting guide (1061).

[0401] The magnetic support (1064) can be coupled with the protrusion (1037) of the holder (1030). The magnetic support (1064) can include a coupling hole (1005A) for coupling with the protrusion (1022) of the protrusion (1037) of the holder (1030). One side of the magnetic support (1064) can be coupled with the first protrusion (1057A) of the holder (1030), and the other side of the magnetic support (1064) can be coupled with the second protrusion (1057B) of the holder (1030).

[0402] The magnetic support member (1064) is combined with the holder (1030), but may also be expressed as a part of the holder (1030). In another embodiment, the magnetic support member (1064) may be expressed as an extension extending from the holder (1030). In another embodiment, the magnetic support member (1064) may be formed integrally with the holder (1030).

[0403] The magnetic support (1064) may include a groove (1064A) for placing the magnetic body (1062). The magnetic body (1062) may be bonded to the groove (1064A) of the magnetic support (1064) by an adhesive. The magnetic support (1064) may also be expressed as a “support,” “mover rigid,” or “bonding portion.”

[0404] The magnetic body (1062) and the magnetic body (1063) may be spaced apart from each other. The magnetic body (1062) and the magnetic body (1063) may be arranged to face each other. The magnetic body (1062) and the magnetic body (1063) may be arranged to face each other in the optical axis direction or the first direction. For example, the magnetic body (64) may be arranged in the groove (1044A) of the housing (1050). For example, the magnetic body (1063) may be coupled to the groove (1044A) of the housing (1050) by an adhesive.

[0405] The magnetic body (1063) may be positioned between the magnetic body (1062) and the tilting guide part (1061). In an embodiment, the tilting guide part (1061) is not positioned between the magnetic body (1062) and the magnetic body (1063), and the magnetic body (1062) and the magnetic body (64) may be positioned on one side of the tilting guide part (1061) with respect to the tilting guide part (1061). The magnetic body (1062) and the magnetic body (64) may be positioned on opposite sides of the optical member (1040) with respect to the tilting guide part (1061). This may reduce the separation distance between the magnetic body (1062) and the magnetic body (1063), and increase the magnetic force (e.g., repulsive force) between the magnetic body (1062) and the magnetic body (1063).

[0406] At least one of the holder (1030) and the housing (1050) can press the tilting guide part (1061) by the repulsive force between the magnetic bodies (1062, 1063), and the tilting guide part (1061) can be brought into close contact with the holder (1030) and / or the housing (1050). In the embodiment, since the magnetic force (e.g., repulsive force) between the magnetic bodies (1062) and (1063) is large, the tilting guide part (1061) can stably support the holder (1030), and thus, a stable OIS operation can be performed.

In another embodiment, the cover plate (1057) may include a magnetic body or may be formed of a magnetic material. For example, the cover plate (1057) may be a magnetic body plate. When the cover plate (1057) is a magnetic plate, the magnetic flux of the magnetic body (1062) leaking to the rear of the magnetic body (1062) can be reduced, the magnetic flux generated from the magnetic body (1062) can be concentrated to the magnetic body (1063), and the repulsive force between the first and magnetic bodies (62, 63) can be increased. As a result, the sagging of the tilting guide part (1061) can be prevented, the tilting guide part (1061) can stably support the holder (1030), stable OIS operation can be performed, and the reliability of OIS operation can be secured.

[0432] The camera device (1200) may include a position sensor (1240) for detecting a displacement of the OIS moving part.

The driver IC (1260) may be expressed as an “OIS driver IC,” a “control unit,” or an “OIS control unit.”

[0447] In the actuator (1320), the path of light incident on the optical member (1040) can be moved on a plane (e.g., XY plane) perpendicular to the first axis (optical axis or Z axis) by the movement of the holder (1030) coupled with the optical member (1040), and thus, the image formed on the image sensor (1540) can be moved in the X-axis direction and / or the Y-axis direction. In the actuator (1320), the movement of the holder (1030) is controlled, so that blurring of the image or shaking of the video caused by shaking of the camera device during image capturing or video capturing due to the user's hand shaking can be corrected.

[0450] The moving unit may be a part that moves in the direction of the optical axis. The moving unit may include a zoom moving unit and an auto focus moving unit. The zoom moving unit may move in the direction of the optical axis to perform a zoom operation. The auto focus moving unit may move in the direction of the optical axis to perform an auto focus operation. The zoom moving unit may include a lens unit (1622). The zoom moving unit may include a magnet (1130). The auto focus moving unit may include a lens unit (1624). The auto focus moving unit may include a magnet (130B).

[0451] The actuator (1310) may include a “zoom and auto focus driving unit” for moving the zoom moving unit and the auto focus moving unit in the optical axis direction. The zoom and auto focus driving unit may include a magnet (1130) and a coil (1120).

[0452] The lens unit (1620) may be alternatively expressed as a “lens assembly” or a “lens group.” For example, the lens unit (1620) may include a plurality of lens units (1622, 1624). In FIGS. 37A and 37B , the lens unit (1620) includes two lens units (1622, 1624), but in other embodiments, the lens unit (1620) may include one or three or more lens units. The lens units (1622, 1624) may be arranged in the first direction or the optical axis direction.

[0453] The actuator (1310) may include a lens unit (1620) and a lens unit (1640) disposed between the actuator (1320). For example, the lens unit (1640) may be a fixed lens unit whose position is fixed and does not move in the optical axis direction. The lens unit (1640) may include a lens array (1642). For example, the lens unit (1640) may further include a lens barrel (1641) coupled with the lens array (1642). The lens unit (1640) may be coupled to the housing (1050) of the actuator (1320). The lens unit (1640) may be coupled to the housing (1050) of the actuator (1320) by an adhesive. The lens barrel (1641) may be coupled to the housing (1050) of the actuator (1320). The lens barrel (1641) can be joined to the housing (1050) of the actuator (1320) by an adhesive.

[0454] For example, the lens barrel (1641) may include at least one engaging hole (1043B) for engaging with at least one engaging protrusion (1043A) of the housing (1610). In the present embodiment, the lens unit (1640) is included in the actuator (1310), but in other embodiments, the lens unit (1640) may be omitted. In embodiments in which the lens unit (1640) is omitted, the housing (1610) of the actuator (1310) may be engaged with the housing (1050) of the actuator (1320).

[0455] Additionally, in the embodiment, any one of 1640, 1622, and 1624 may be represented as a “first lens unit”, another one of 1640, 1622, and 1624 may be represented as a “second lens unit”, and the remaining one of 1640, 1622, and 1624 may be represented as a “third lens unit”.

[0456] In an embodiment, the first lens unit (1640) may be a “fixed lens group”, and each of the second lens unit (1622) and the lens unit (1624) may be a “movable lens group” that can move in the optical axis direction.

[0457] For example, the first lens unit (1640) can perform a focus function that focuses parallel light at a specific location. In addition, the second lens unit (1622) can perform a variator function that refocuses the image focused by the first lens unit (1640), which is a focuser, at another location. Meanwhile, in the second lens unit (1622), the distance to the subject or the image distance may change significantly, resulting in a large change in magnification, and the second lens unit (1622) can play an important role in changing the focal length or magnification of the optical system. Meanwhile, the image focused by the second lens unit (1622) may have a slight difference depending on the location. The lens unit (1624) can perform a position compensation function for the image focused by the variator. For example, the lens unit (1624) may perform a compensator function that accurately focuses the point imaged by the second lens unit (1622) onto the pixels of the image sensor (1540). For example, the second lens unit (1622) may be a zoom lens assembly that performs a zooming function, and the lens unit (1624) may be a focus lens assembly that performs a focusing function.

[0458] The housing (1610) may be disposed between the housing (1050) of the actuator (1320) and the image sensor unit (e.g., the sensor base (1550)). The housing (1610) may also be alternatively expressed as a “base,” a “case,” or a “holder.” The housing (1610) may be disposed inside the cover member (1300). The housing (1610) may have a polyhedral (e.g., rectangular parallelepiped) shape having a space therein to accommodate the lens unit (1620) and the zoom and auto focus driving unit. For example, the housing (1610) may include an upper portion (or upper plate), a lower portion (or lower plate), and a plurality of side portions (11141-1 to 11141-4) disposed between the upper portion and the lower portion. The upper portion of the housing (1610) may face the upper plate (1301) of the cover member (1300), and the side portions (11141-1 to 11141-4) may face the side plate (1302) of the cover member (1300). The side portions (11141-1 to 11141-4) may be alternatively expressed as “side plates” or “side walls”. The first side portion (1141-1) and the second side portion (1141-2) of the housing (1610) may face each other in a first direction or may be positioned opposite each other, and the third side portion (1141-3) and the fourth side portion (1141-3) of the housing (1610) may face each other in a third direction or may be positioned opposite each other.

In addition, an opening (1144A) (or third hole) for placing or settling a first coil (1120A) may be formed on a third side (1141-3) of the housing (1610), and an opening (1041C) (or third hole) for placing or settling a second coil (1120B) may be formed on a fourth side (1141-4) of the housing (1610). Each of the openings (1144A, 1144B) of the housing (1610) is in the form of a through hole, but in other embodiments, the openings (1144A, 1144B) of the housing (1610) may be in the form of a groove.

[0460] The housing (1610) may include a guide portion (1049) for guiding the movement of the lens portion (1622) and the lens portion (1624). The guide portion (1049) may be located on the inside of the housing (1610). For example, the guide portion (1049) may be formed on the inner surface of at least one of the side portions (1141-3, 1141-4) of the housing (1610). The guide portion (1049) may be in the form of a groove or rail extending in the first direction or the optical axis direction. For example, the guide portion (1049) may include a first guide portion formed on the inner surface of the side portion (1141-3) of the housing (1610) and a second guide portion formed on the inner surface of the side portion (1141-4) of the housing (1610). At least a part of a first cloud member (BM1) described later may be arranged in the first guide portion of the housing (1610), and at least a part of a second cloud member (BM2) described later may be arranged in the second guide portion of the housing (1610).

[0461] The housing (1610) may include at least one opening (1621A, 1621B) formed in an upper portion of the housing and exposing a portion of the lens portion (1622, 1624). The actuator (1310) may further include at least one cover (1614, 1615) covering the at least one opening (1621A, 1621B) of the housing (1610). In other embodiments, at least one of the openings (1621A, 1621B) may not be formed, and at least one of the covers (1614A, 1614B) may be omitted.

[0462] The actuator (1310) may further include a cover (1616) covering the opening (1041B) of the housing (1610). The cover (1616) may be coupled to a side (1141-2) of the housing (1610).

[0465] The first lens holder (1029) may include a lens barrel (1029A) on which a lens array (1049) is arranged, and a support member (1029B) coupled with the lens barrel (1029A). For example, the lens barrel (1029A) may have a barrel shape and may include an opening (1029C) (or hole) for coupling the lens array (1049). A first side (or first surface) of the support member (1029B) may be coupled to the lens barrel (1029A). The support member (1029B) may face or overlap one side (e.g., 1141-3) of the housing (1610) in a third direction. A first magnet (1130A) may be arranged or mounted on a second side (or second surface) of the support member (1029B). The second side (or second surface) of the support (1029B) may be a surface facing one side (e.g., 1141-3) of the housing (1610) and may be an opposite surface of the first side (or first surface) of the support (1029B).

[0466] The lens unit (1622) may be formed with at least one first groove (or first guide groove) (1013A) for arranging at least another portion of the first cloud member (BM1). The at least one first groove (1013A) may be formed in the lens barrel (1029A). The at least one first groove (1013A) may be formed in the support (1029B). For example, at least one first groove (1013A) of the lens unit (16220) may correspond to, face, or overlap the first guide portion of the housing (1610). For example, the first groove (1013A) may be arranged on at least one of the upper side or the lower side of the first magnet (1130A). The number of first grooves (1013A) may be one or two or more.

[0467] The lens unit (1624) may include a second lens holder (1039) and a lens array (1059) disposed in the second lens holder (1039). The lens array (1059) may include a single lens or a plurality of lenses (1F, 1G, 1H). The number of lenses included in the lens array (1059) may be two or more.

[0468] The second lens holder (1039) may include a lens barrel (1039A) in which a lens array (1059) is arranged and a support (1039B) coupled with the lens barrel (1039A). For example, the lens barrel (1039A) may have a barrel shape and may include an opening (1039C) (or hole) for coupling the lens array (1049).

[0469] A first side (or first surface) of the support (1039B) may be coupled to the lens barrel (1039A). The support (1039B) may face or overlap with another side (e.g., 1141-4) of the housing (1610) in a third direction. A second magnet (1130B) may be arranged or mounted on a second side (or second surface) of the support (1039B). The second side (or second surface) of the support (1039B) may be a surface facing the other side (e.g., 1141-4) of the housing (1610) and may be an opposite surface of the first side (or first surface) of the support (1039B).

[0470] The lens unit (1624) may include at least one second groove (1013B) (or second guide groove) for arranging at least another portion of the second cloud member (BM2). The at least one second groove (1013B) may be formed in the lens barrel (1039A). The at least one second groove (1013B) may be formed in the support unit (1039B). For example, the at least one second groove (1013B) may correspond to, face, or overlap the second guide unit of the housing (1610). For example, the second groove (1013B) may be arranged on at least one of the upper side or the lower side of the second magnet (1130B). The number of second grooves (1013B) may be 1 or 2 or more.

[0471] A plurality of lenses (1001A to 1001H) included in each of the lens arrays (1049, 1059) may be sequentially arranged or arranged in a first direction. For example, each of the lens arrays (1049, 1059) may include various types of optical lenses. For example, each of the lens arrays (1049, 1059) may include at least one of a front lens having positive power and a rear lens having negative power. The distance in the optical axis direction between the lens units may be varied by the zoom and auto focus driving unit.

[0472] The cloud members (BM1, BM2) can be brought into contact with the first and second guide parts of the housing (1610) and the first and second grooves (1013A, 1013B) of the lens parts (1622, 1624) at two or more points. When the lens parts (1622, 1624) move in the optical axis direction by the first and second guide parts of the housing (1610) and the first and second grooves (1013A, 1013B) of the lens parts (1622, 1624), decentering or tilting can be prevented. As a result, the alignment between the plurality of lens arrays is well matched, and the change in the angle of view or the occurrence of out-of-focus can be prevented, so that the image quality or resolution of the camera device (1200) can be significantly improved.

[0473] The actuator (1310) may include a cloud member (BM1, BM2) disposed between the housing (1610) and the lens unit (1620). The cloud member (BM1, BM2) may be disposed between the housing (1610) and the support member (1039A, 1039B) of the lens unit (1620). The cloud member (BM1, BM2) may be disposed between the guide member (1049) of the housing (1610) and the groove (1013A, 1013B) of the support member (1039A, 1039B) of the lens unit (1620).

[0474] The cloud member may be expressed as a “ball member”, “ball”, or “ball bearing”. For example, the cloud member (BM1, BM2) may include at least one ball. The cloud member (BM1, BM2) may be in contact with at least one of the housing (1610) and the lens unit (1620) and may support the lens unit (1620). When the lens unit (1620) moves in the first direction, the cloud member (BM1, BM2) may roll or slide between the lens unit (1620) and the housing (1610), and may reduce the frictional force between the lens unit (1620) and the housing (1610).

[0475] The cloud member may include a first cloud member (BM1) disposed between one side of the housing (1610) (e.g., 1141-3) and the lens unit (1622), and a second cloud member (BM2) disposed between the other side of the housing (1610) (e.g., 1141-4) and the lens unit (1624). For example, the first cloud member (BM1) may be disposed between the first guide unit of the housing (1610) and the lens unit (1622) (e.g., the support unit (1029B)). The second cloud member (BM2) may be disposed between the second guide unit of the housing (1610) and the lens unit (1624) (e.g., the support unit (1039B)). The first cloud member (BM1) may include a plurality of balls (B1 to B4), and the second cloud member (BM2) may include a plurality of balls (B5 to B8). The number of balls included in each of the first and second cloud members may be two or more. Each of the balls (B1 to B8) may be made of a metal material, a plastic material, or a resin material, but is not limited thereto. Each of the balls (B1 to B8) may have a circular shape and may have a diameter sufficient to support movement of the lens unit (1620).

[0476] The zoom and auto focus driving unit can move the lens unit (1622) in a first direction and move the lens unit (1624) in the first direction. The zoom and auto focus driving unit can include a first magnet (1130A) disposed in the lens unit (1622), a first coil (1120A) disposed in the housing (1610) to face the first magnet (1130A), a second magnet (1130B) disposed in the lens unit (1624), and a first coil (1120B) disposed in the housing (1610) to face the second magnet (1130A).

[0477] The first magnet (1130A) may be placed in the first lens holder (1029) of the lens unit (1622), and the second magnet (1130B) may be placed in the second lens holder (1039) of the lens unit (1624). The first magnet (1130A) may be placed in the support (1029B) of the first lens holder (1029), and the second magnet (1130B) may be placed in the support (1039B) of the second lens holder (1039). For example, each of the first and second magnets (1130A, 1130B) may be a two-pole magnet including one N pole and one S pole, or a single-pole magnet. In another embodiment, each of the first and second magnets (1130A, 1130B) may be a four-pole magnet or a bipolar magnet including two N poles and two S poles.

[0478] The first coil (1120A) may include at least one coil unit corresponding to, opposing, or overlapping the first magnet (1130A) in the third direction. In the embodiments of FIGS. 38A and 38B , the first coil (1120A) includes two coil units (1120A1, 1120A2), but in other embodiments, the number of coil units included in the first coil (1120A) may be one or three or more.

[0479] The coil units (1120A1, 1120A2) may be arranged in a first direction. For example, the coil units (1120A1, 1120A2) may be arranged in parallel in the first direction. The coil units (1120A1, 1120A2) may correspond to, face, or overlap the first magnet (1130A) in a third direction. Each of the coil units (120A1, 120A2) may be a closed curve having a hollow (or hole) or may be in the shape of a ring. Each of the coil units (120A1, 120A2) may be in the shape of a coil ring wound in a clockwise or counterclockwise direction around an axis that is perpendicular to the optical axis and parallel to the direction from one side (1141-3) of the housing (1610) to the other side (1141-4). For example, the hollow or hole of each of the coil units (1120A1, 1120A2) may face the first magnet (1130A) in a third direction.

[0480] The second coil (1120B) may include at least one coil unit corresponding to, opposing, or overlapping the second magnet (1130B) in the third direction. In the embodiments of FIGS. 38A and 38B, the second coil (1120B) includes two coil units (1120B1, 1120B2), but in other embodiments, the number of coil units included in the second coil (1120B) may be one or three or more.

[0481] The coil units (1120B1, 1120B2) may be arranged in a first direction. For example, the coil units (1120B1, 1120B2) may be arranged in parallel in the first direction. The coil units (1120B1, 1120B2) may correspond to, face, or overlap the second magnet (1130B) in a third direction. Each of the coil units (1120B1, 1120B2) may be a closed curve having a hollow (or hole) or may be in the shape of a ring. Each of the coil units (1120B1, 1120B2) may be in the shape of a coil ring wound in a clockwise or counterclockwise direction around an axis that is perpendicular to the optical axis and parallel to the direction from one side (1141-3) of the housing (1610) to the other side (1141-4). For example, the hollow or hole of each of the coil units (1120B1, 1120B2) may face the second magnet (1130B) in a third direction.

[0482] A first driving signal (e.g., a first current) may be applied to the first coil (1120A), and a second driving signal (e.g., a second current) may be applied to the second coil (1120B). The lens unit (1622) may be moved in the first direction by an electromagnetic force resulting from the interaction between the first coil (1120A) and the first magnet (1130A). In addition, the lens unit (1624) may be moved in the first direction by an electromagnetic force resulting from the interaction between the second coil (1120B) and the second magnet (1130B).

[0483] For example, the coil units (120A1, 120A2) of the first coil (1120A) may be connected in parallel with each other. The coil units (120B1, 120B2) of the second coil (1120B) may be connected in parallel with each other. The first driving signal applied to the first coil (1120A) may be distributed and supplied to each of the coil unit (1120A1) and the coil unit (1120A2). In addition, the second driving signal applied to the second coil (1120B) may be distributed and supplied to each of the coil unit (1120A1) and the coil unit (1120A2). By connecting the coil units (1120A1, 1120A2) in parallel, heat generated from each coil unit (1120A1, 1120A2) may be reduced. Additionally, by connecting the coil units (1120B1, 1120B2) in parallel, the heat generated from each coil unit (1120B1, 1120B2) can be reduced.

[0484] In another embodiment, the coil units (1120A1, 1120A2) may not be connected to each other, and the coil units (1120B1, 1120B2) may not be connected to each other. In addition, each of the coil units (1120A1, 1120A2) may be supplied with a separate and independent driving signal, and each of the coil units (1120B1, 1120B2) may be supplied with a separate and independent driving signal.

[0485] In another embodiment, the coil units (1120A1, 1120A2) may be connected in series with each other, and the coil units (1120B1, 1120B2) may be connected in series with each other. A first driving signal may be supplied to the series-connected coil units (1120A1, 1120A2). A second driving signal may be supplied to the series-connected coil units (1120B1, 1120B2).

[0486] By controlling the driving signals supplied to the first coil (1120A) and the second coil (1120B), the movement of each of the lens units (1622, 1624) can be controlled. As the movement of each of the lens units (1622) and the lens units (1624) is controlled, the position (or displacement) of each of the lens units (1622) and the lens units (1624) can be controlled, thereby performing zooming and auto-focusing of the camera device (1200).

[0487] The actuator (1310) may include a first yoke (1093A) disposed in the lens unit (1622) and a second yoke (1093B) disposed in the lens unit (1624). The first yoke (1093A) may be disposed in the first lens holder (1029). The first yoke (1093A) may be coupled with the first lens holder (1029). The second yoke (1093B) may be disposed in the second lens holder (1039). The second yoke (1093B) may be coupled with the second lens holder (1039). The first yoke (1093A) can increase the electromagnetic force due to the interaction between the first magnet (1130A) and the first coil (1120A), and the second yoke (1093B) can increase the electromagnetic force due to the interaction between the second magnet (1130B) and the second coil (1120B). The driving force for moving the lens unit (1620) can be improved by the first and second yokes (93A, 93B), thereby reducing power consumption.

[0488] For example, the first yoke (1093A) may be disposed between the first magnet (1130A) and the first lens holder (1029), and the second yoke (1093B) may be disposed between the second magnet (1130B) and the second lens holder (1039). For example, the first yoke (1093A) may be disposed on the support (1029B), and the second yoke (1093B) may be disposed on the support (1039B). The first yoke (1093A) may be coupled to the support (1029B), and the second yoke (1093B) may be coupled to the support (1039B).

[0489] At least a portion of the first yoke (1093A) can surround at least a portion of a side surface of the first magnet (1130A). The first yoke (1093A) can surround at least one of the side surfaces of the first magnet (1130A). For example, the first yoke (1093A) can include segmented members, each of which can be positioned on a side surface of the first magnet (1130A). The description of the first yoke (1093A) can be applied to or analogized with the second yoke (1093B).

[0490] The actuator (1310) may include a substrate (1190) electrically connected to a first coil (1120A) and a second coil (1120B). For example, the substrate (1190) may be a printed circuit board.

The driver IC (1542) may be disposed or mounted on any one of the first and second circuit boards (1191, 1192). The driver IC (1542) may be disposed or mounted on a second surface (191B, 192B) of any one of the first and second circuit boards (1191, 1192). The driver IC (1542) may be coupled to the second surface (1191B, 1192B) of one of the first and second circuit boards (1191, 1192) by solder or a conductive adhesive.

[0508] Referring to FIG. 38B, the driver IC (1542) may be placed on the second surface (1191B) of the first circuit board (1191). The driver IC (1542) may be placed between the first circuit board (1191) and the side plate (1302) of the cover member (1300). The second circuit board (1192) may be electrically connected to the second substrate (1532) of the substrate portion (1530), and thus, there may be a spatial constraint on the second circuit board (1192) for placing the driver IC (1542).

[0509] In the embodiment, the reason for arranging the driver IC (1542) on the second surface (1191B) of the first circuit board (1191) is to efficiently release heat generated from the driver IC (1542) outside the camera device (1200). By arranging the driver IC (1542) on the opposite side of the lens unit (1640, 620) with respect to the board unit (1190), the influence of the heat generated from the driver IC (1542) on the lens unit (1640, 1620) is reduced. Through such arranging of the driver IC (1542), the internal temperature of the actuator (1310) can be reduced.

[0511] The driver IC (1542) may be electrically connected to the first position sensor (1071) and the second position sensor (1072). The driver IC (1542) may be electrically connected to the first coil (1120A) and the second coil (1120B). The driver IC (1542) may supply a driving signal or power to the first position sensor (1071) and the second position sensor (1072). For example, the driver IC (1542) may supply a driving signal or power to input terminals of each of the first and second position sensors (1071, 1072).

[0512] The driver IC (1542) can adjust or control the first driving signal of the first coil (1120A) and the second driving signal of the second coil (1120B) based on the outputs of the first position sensor (1071) and the second position sensor (1072), respectively, to provide a magnification adjustment function and an auto-focus function. The driver IC (1542) can include at least one of an analog-to-digital converter (ADC), an amplifier, a PID controller, or a memory.

[0513] The driver IC (1542) can supply a driving signal to the coil (1120). The driver IC (1542) can supply a first driving signal to the first coil (1120A) and a second driving signal to the second coil (1120B).

[0514] The driver IC (1542) receives an output signal of the first position sensor (1071) and an output signal of the second position sensor (1072).

[0516] The driver IC (1542) can adjust or control the first driving signal based on the result of comparing the first digital value with the first target value. The first target value may be a reference digital value corresponding to the target zoom position of the lens unit (1622).

[0517] The driver IC (1542) can generate a second driving signal using the output signal of the second position sensor (1072). The driver IC (1542) can generate a second driving signal using the output signals of the sensors of the second position sensor (1072). The driver IC (1542) can convert the output signal of the second position sensor (1072) into analog-to-digital and generate a second digital value, and can generate a second driving signal using the second digital value.

[0518] The driver IC (1542) can adjust or control the second driving signal based on the result of comparing the second digital value with the second target value. The second target value may be a reference digital value corresponding to the target focus position of the lens unit (1624).

[0519] The driver IC (1542) can store data (or digital value) of the first position sensor (1071) corresponding to the movement range (or displacement) of the lens unit (1622) and data (or digital value) of the second position sensor (1072) corresponding to the movement range (or displacement) of the lens group (1624). At this time, the data of the first position sensor (1071) may be data (or reference digital value) regarding the output of the first position sensor (1071) corresponding to the movement range (or displacement) of the lens unit (1622) obtained through calibration. In addition, the data of the second position sensor (1072) may be data (or reference digital value) regarding the output of the second position sensor (1071) corresponding to the movement range of the third lens group obtained through calibration. In another embodiment, the reference digital values ​​of the first and second position sensors (1071, 1072) may be stored in a data storage unit, which may be built into the driver IC (1542) or provided separately outside the driver IC (1542).

[0520] The driver IC (1542) can transmit or receive data with the host using data communication using a protocol, for example, I2C communication. The driver IC (1542) can include first and second terminals for receiving power (VDD, VSS) from the host, a third terminal for transmitting and receiving a clock signal (CLK) to and from the host, and a fourth terminal (SDA) for transmitting and receiving data to and from the host.

[0522] The image sensing unit (1330) may include an image sensor (1540) that receives and detects light passing through the optical member (1040) of the actuator (1320) and the lens units (1640, 1622, 1624) of the actuator (1310) and converts the detected light into an electrical signal. For example, the image sensor (1540) may include an imaging area for detecting light. Here, the imaging area may be expressed as an effective area, a light-receiving area, a sensor surface, or an active area. For example, the imaging area may include a plurality of pixels on which an image is formed. The image sensor (1540) may face the lens unit (1620) in the optical axis direction or in the first direction. For example, the image sensor (1540) may face the lens unit (1624) in the optical axis direction or in the first direction.

[0523] The image sensing unit (1330) may include a substrate unit (1530) electrically connected to the image sensor (1540). In another embodiment, the substrate unit (1530) may be replaced with a “sensor substrate unit.” The fixing unit may include the substrate unit (1530).

The substrate portion (1530) may include a plurality of terminals (252) that are electrically connected to a plurality of terminals (1254) of the substrate portion (1190). The plurality of terminals (1254) of the substrate portion (1190) and the plurality of terminals (252) of the substrate portion (1530) may be coupled by solder or a conductive adhesive.

[0525] The substrate portion (1530) may include a first substrate (1531) on which an image sensor (1540) is disposed or mounted. The first substrate (1531) may be disposed behind the lens portion (1624). For example, the image sensor (1540) may be disposed on a first surface of the first substrate (1531), and the first surface of the first substrate (1531) may be a surface facing the actuator (1310) or the lens portion (1620). The first substrate (1531) may also be expressed as a “sensor substrate.”

[0526] The substrate portion (1530) may include a second substrate (1532) connected to the first substrate (1531) and extending in the first direction. A plurality of terminals (252) may be disposed on the second substrate (1531). The second substrate (1532) may be disposed parallel to the second circuit substrate (1192) of the substrate portion (1190). The second substrate (1532) may be disposed on the outside of the second circuit substrate (1192) of the substrate portion (1190). The second substrate (1532) may be disposed opposite the side portion (1141-4) of the housing (1610). The second substrate (1532) may be positioned so as to face the second circuit substrate (1192) of the substrate portion (1190) in the third direction, and may be positioned on the second surface (1192B) of the second circuit substrate (1192). The substrate portion (1530) may include a folded portion between the first substrate (1532) and the second substrate (1532).

[0527] The substrate portion (1530) may include a connector (1534) including a port or socket for electrically connecting with an external device. The substrate portion (1530) may further include a third substrate (533) connecting the second substrate (1532) and the connector (1534). The substrate portion (1530) may include a fourth substrate (1535) extending from the second substrate (1532) toward the substrate portion (1250) and electrically connected to the substrate portion (1250). For example, the fourth substrate (1535) may be electrically connected to the second circuit board (1250B) of the substrate portion (1250). The fourth substrate (1535) may include a connector (1536) electrically connected to the connector (1340) of the second circuit board (1250B) of the substrate portion (1250).

[0528] The substrate portion (1530) may be a printed circuit board. For example, each of the first to fifth substrates (1531, 1532, 1533, 1534) may include at least one of a rigid substrate and a flexible substrate.

[0529] The image sensing unit (1330) may include a sensor base (1550) disposed between a substrate unit (1530) and an actuator (1310) and a filter (1560) disposed on the sensor base (1550). The sensor base (1550) may be disposed between a first substrate (1531) of the substrate unit (1530) and a housing (1610). The sensor base (1550) may be coupled, attached, or fixed to a first surface of the first substrate (1531) by an adhesive. The lower portion or bottom surface of the sensor base (1550) may be coupled to the first surface of the first substrate (1531) by an adhesive. The sensor base (1550) may include a mounting portion (1550A) for placing or mounting the filter (610). For example, the mounting portion (1550A) may be formed on a first surface of the sensor base (1550). The first surface of the sensor base (1550) may be a surface facing the housing (1610) in the first direction. For example, the mounting portion (1500A) may be in the form of a recess, cavity, or hole that is sunken into the first surface of the sensor base (1550). In another embodiment, the mounting portion may be in the form of a protrusion that protrudes from the first surface of the sensor base (1550). The sensor base (1550) may also be expressed as a “holder.”

[0530] The filter (1560) may be disposed between the image sensor (1540) and the lens unit (1620). The filter (1560) may be disposed on the mounting portion (1550A) of the sensor base (1550). For example, the mounting portion (1550A) of the sensor base (1550) may include an inner surface and a bottom surface, and the filter (1560) may be disposed on the bottom surface of the mounting portion (1500A) of the sensor base (1550). The sensor base (1550) may include an opening (1552) (or a through hole) so that light passing through the filter (1560) may be incident on the image sensor (1540). The opening (1552) may correspond to, face, or overlap the image sensor (1540) (e.g., an imaging area). For example, the opening (552) may be formed on the bottom surface of the mounting portion (1550A).

[0531] The filter (1560) may block light of a specific frequency band from passing through the lens unit (1620) from entering the image sensor (1540). For example, the filter (1560) may be an infrared blocking filter. For example, the filter (1560) may be arranged parallel to an xy plane perpendicular to the first direction. For example, the filter (1560) may be attached to the bottom surface of the mounting portion (550A) of the sensor base (1550) by an adhesive material (not shown), such as UV epoxy. The filter (1560) and the image sensor (1540) may be arranged spaced apart from each other so as to face each other in the first direction.

[0532] For accurate zooming and autofocus operation, the zoom position of the lens unit (1622) and the focus position of the lens unit (1624) must be set considering the distance (or separation distance) between the subject and the camera device (or lens). This setting process is called "calibration" or "zoom calibration." The distance to the subject can be obtained using a distance measuring device (e.g., a laser diode) provided in the camera device (1200).

[0533] For example, if the distance between the camera device (1200) (or the user) and the subject is far, the zoom ratio may be set to a high ratio or changed to a high ratio. On the other hand, if the distance between the camera device and the subject is close, the zoom ratio may be set to a low ratio or changed to a low ratio. Based on this zoom ratio, the stroke or displacement of the lens unit (1622) may be set or changed. The position at which the lens unit (1622) is positioned or moved so as to realize an accurate zoom ratio in this way is referred to as a “zoom position.” In addition, the position, displacement, or stroke of the lens unit (1624) so ​​that the subject is accurately focused at the “zoom position” of the lens unit (1622) is referred to as a “focus position.” Therefore, the focus position may be changed depending on the “zoom position” and distance information from the subject. The lens unit (1622) can be moved to the zoom position using the output of the position sensor (1071) and the electromagnetic force between the first coil (1120A) and the first magnet (1130A). The lens unit (1624) can be moved to the focus position using the output of the position sensor (1072) and the electromagnetic force between the second coil (1120B) and the second magnet (1130B).

[0534] In order to implement high resolution, the size of the image sensor may increase, and in order to perform a high-magnification zoom function, the stroke distance of the lens unit may increase. In addition, as the communication speed of the driver IC (1542) increases and the amount of information that the driver IC (1542) must process increases, the amount of heat generated from the driver IC (1542) may increase, which may become a factor in increasing the temperature of the camera device (1200). The driver IC (1542) may be a heat source with a high heat generation temperature.

[0535] An increase in the temperature of the camera device (1200) may cause demagnetization of the magnets (1130A, 1130B) of the actuator (1310), which may cause errors in the OIS operation. In addition, an increase in the temperature of the camera device may cause changes in the output signals of the position sensors (1071, 1072), which may deteriorate the accuracy and reliability of the zoom and autofocus operations.

[0536] An increase in temperature of the camera device (1200) may affect the optical performance of each of the lenses included in the lens units (1640, 1622, 1624). That is, the shape of the lens may be deformed due to an increase in temperature of the camera device (1200). For example, the lens may expand or contract due to heat. The housing (1050) of the actuator (1320) and the lens unit (1640) of the actuator (1310) may be coupled to each other by an adhesive (e.g., epoxy), and an active alignment process may be performed while the housing (1050) and the lens unit (1640) are coupled. Due to the increase in temperature of the camera device (1200), misalignment of the optical axis may occur during this active alignment process due to a change in the shape of the lenses (1001A to 1001H) of the lens units (1640, 620). In this case, the misalignment may be a misalignment between the lens units (1640, 1622, 1624).

[0537] In an embodiment, in order to facilitate the dissipation of heat generated from the driver IC (1542) and to increase heat dissipation efficiency, the driver IC (1542), which is a heat source, may be placed outside the substrate portion (1190). In addition, in an embodiment, the driver IC (1542) may be placed outside the housing (1610). In an embodiment, the driver IC (1542) may be placed outside the housing (1610).

[0538] The driver IC (1542) may be disposed between the first circuit board (1191) of the substrate (1190) and the side plate (1302) of the cover member (1300). The driver IC (1542) may be in contact with the side plate (1302) of the cover member (1300). Heat generated from the driver IC (1542) may be discharged to the outside through the side plate (1302) of the cover member (1300). The driver IC (1542) may be disposed on a second surface (1191B) opposite to the first surface (1191A) of the first circuit board (1191) on which the first coil (1120A) is disposed. In another embodiment, the driver IC (1542) and the side plate (1302) of the cover member (1300) may be spaced apart from each other.

[0539] In another embodiment, the side plate (1302) of the cover member (1300) may include an opening or through hole exposing the driver IC (1542).

[0540] Another embodiment may further include a heat dissipation member disposed between the driver IC (1542) and the cover member (1300). The heat dissipation member may be formed of a metal having high thermal conductivity.

[0541] The driver IC (1542) may be positioned closer to the image sensor (1540) than the lens unit (1640). This is to position the driver IC (1542) away from the fixed lens unit (1640). Although the effect of heat on the lens unit (1622, 1624) may be compensated for by moving the lens unit (1622, 1624), the lens unit (1640) cannot move, so the deformation of the lens unit due to heat cannot be compensated for at all. In order to prevent misalignment, it may be important to minimize the deformation of the lens unit (1640) due to heat. Therefore, positioning the driver IC (1542) away from the lens unit (1640) may be an important factor in preventing misalignment. The separation distance (or shortest distance) between the driver IC (1542) and the lens unit (1640) may be greater than the separation distance between the driver IC (1542) and the lens unit (1622). The separation distance (or shortest distance) between the driver IC (1542) and the lens unit (1640) may be greater than the separation distance between the driver IC (1542) and the lens unit (1624).

[0542] For example, the side plate (1302) of the cover member (1300) may be positioned closer to the driver IC (1542) than the first circuit board (1191) of the substrate (1190). In the third direction, the driver IC (1542) may overlap with the lens unit (1624). In the third direction, the driver IC (1542) may not overlap with the lens unit (1622). In another embodiment, in the third direction, the driver IC (1542) may overlap with the lens unit (1622) and may not overlap with the lens unit (1624). In the third direction, the driver IC (1542) may overlap with the side plate (1302) of the cover member (1300).

[0543] The driver IC (1542) may not overlap with the first coil (1120A) in the optical axis direction. The driver IC (1542) may not overlap with the position sensor (1071) in the optical axis direction. This may be because the driver IC (1542) is positioned on the outside of the first circuit board (1191).

[0544] In an embodiment, the influence of heat generated from a driver IC (1542) on a lens (1001A, 1001B, 1001C) of a lens unit (1640) can be reduced, a change in the curvature of the lens (1001A, 1001B, 1001C) caused by heat can be suppressed, a deterioration in the optical performance of the lens unit (1640, 620) can be prevented, and the occurrence of misalignment in an active alignment process can be prevented.

[0545] Fig. 42 shows experimental results for horizontal and vertical shifts of comparative examples and embodiments. The comparative example of Fig. 42 may be an example in which the driver IC is located on the inside of the substrate portion (1190). That is, in the comparative example, the driver IC is disposed on the first surface (1192A) of the second circuit board (1192) of the substrate portion (1190). In the comparative example, the driver IC may be disposed in the hollow of the coil unit (120B1) of the second coil (1120B). The X-axis represents time, and the Y-axis represents the magnitude of the horizontal and vertical shift (HV Shift). Fig. 42 shows the result of performing an active alignment process after the housing (1050) and the lens portion (1640) are joined by an adhesive.

[0546] In Fig. 42, horizontal and vertical shift (HV Shift) may refer to a phenomenon in which the focal length changes due to the difference in paths of light rays incident on the left and right sides of the lens and light rays incident on the top and bottom sides of the lens. Horizontal and vertical shift may occur when the left and right curved surfaces and the top and bottom curved surfaces of the lens are not precisely processed according to the predetermined design. Horizontal and vertical shift may also occur when the left and right curved surfaces and the top and bottom curved surfaces of the lens are deformed due to heat.

[0547] Referring to the graph (g1) according to the comparative example of Fig. 42, in the comparative example, the HV shift increases over time, and the increase in HV shift (K4=K2-K1) from the initial time point (t0) to the preset time point (t1) is large. As a result, in the comparative example, the optical performance of the lens unit (1640, 620) may deteriorate due to heat generation of the driver IC, and misalignment may occur in the active alignment process.

[0548] On the other hand, referring to the graph (g2) according to the embodiment, the HV shift slightly increases over time, and the increase amount (K3) of the HV shift from the initial time point (t0) to the preset time point (t1) is small. According to the experimental results, the increase amount (K3) of the HV shift according to the embodiment is about one-eighth of the increase amount (K3) of the HV shift according to the comparative example. Therefore, in the embodiment, the increase phenomenon of the HV shift due to the heat generation of the driver IC (1542) is significantly small, and thereby, the deterioration of the optical performance of the lens unit (1640, 1620) can be prevented, and the occurrence of misalignment can be prevented in the active alignment process.

[0550] Referring to FIG. 43, the actuator (1310) may further include a heat dissipation member (1380) disposed on the driver IC (1542). The heat dissipation member (1380) may cover at least a portion of the surface of the driver IC (1542).

[0551] For example, the heat dissipation member (1380) may be disposed on the upper surface of the driver IC (1542). The heat dissipation member (1380) may be disposed between the upper surface of the driver IC (1542) and the side plate (1302) of the cover member (1300). The heat dissipation member (1380) may be in contact with the side plate (1302) of the cover member (1300).

[0552] In another embodiment, the side plate (1302) of the cover member (1300) may be formed with an opening or through hole that exposes at least a portion of the heat dissipation member (1380).

[0553] In another embodiment, the heat dissipation member (1380) may contact or surround the top and side surfaces of the driver IC (1542). The heat dissipation member (1380) may be formed of a heat dissipating plastic or a heat dissipating resin. For example, the heat dissipation member (1380) may be formed of a heat dissipating epoxy. The heat dissipation member (1380) may improve the heat dissipation efficiency of the driver IC (1542).
