[0061] Hereinafter, embodiments of the present invention that can specifically achieve the above purpose will be described with reference to the attached drawings.

[0062] 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.

[0063] 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.

[0064] 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."

[0065] 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 is described using a Cartesian coordinate system (x, y, z), but 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 be axes in a direction perpendicular to the Z-axis, which is the optical axis (OA) direction.

[0066] In addition, the Z-axis direction, which is the optical axis (OA) direction, can be defined as one of the 'first direction', the 'second direction', and the 'third direction', the X-axis direction can be defined as another of the 'first direction', the 'second direction', and the 'third direction', and the Y-axis direction can be defined as another of the 'first direction', the 'second direction', and the 'third direction'. For example, the first direction can be a direction perpendicular to the imaging area (or sensor surface) of the image sensor.

[0067] In addition, the X-axis (or Y-axis) can be defined as either the "first axis" or the "second axis," the X-axis (or Y-axis) direction can be defined as either the "first-axis direction" or the "second-axis direction," the Y-axis (or X-axis) can be defined as the other of the "first axis" or the "second axis," and the Y-axis (or X-axis) direction can be defined as the other of the "first-axis direction" or 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. In addition, the first-axis direction can be a direction parallel to the first axis, and the second-axis direction can be a direction parallel to the second axis.

[0068] Additionally, for example, the optical axis may be the optical axis of a lens mounted on a lens barrel. Or, for example, the optical axis may be an axis that is perpendicular to the imaging area of ​​the image sensor and passes through the center of the imaging area. Additionally, the expression "terminal" below may be replaced with a pad, an electrode, or a conductive layer.

[0069] 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).

[0070] A camera device according to an embodiment may perform a shake correction function and an auto-focusing function. The 'shake correction function' may be a function of moving a lens in a direction perpendicular to the optical axis direction or tilting 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 of automatically adjusting the focus 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. Hereinafter, the "camera device" may be expressed as a "camera", an "actuator", a "camera module", a "camera", or a "photographer".

[0072] Referring to FIGS. 1 to 13, the camera device (200) may include a fixed portion, an AF moving portion, an OIS moving portion (100), and a support portion. The OIS moving portion (100) may also be expressed as a “moving portion,” a “shaking portion,” a “tilting portion,” or a “moving portion.”

[0073] A fixture may be a fixed element, i.e., the fixture may not move along the optical axis. Alternatively, the fixture may not move or tilt in a direction perpendicular to the optical axis. Furthermore, a component coupled to the fixture may also be a fixed element.

[0074] The fixed part may include a housing (210). The fixed part may include a cover member (300). For example, the fixed part may include a configuration that is disposed or coupled to the housing (210) or the cover member (300). For example, the fixed part may include at least one of a magnet (310), a magnetic body (31), and a movement-restraining member (80) disposed in the housing (210).

[0075] The AF moving unit can move in the direction of the optical axis with respect to the fixed unit. For example, the AF moving unit may include a bobbin (110). The AF moving unit may further include a component (e.g., a magnet (130)) coupled to the bobbin (110). In another embodiment, the AF moving unit may further include a lens module (400, see FIG. 17) coupled to the bobbin (110).

[0076] The OIS moving unit (100, see FIG. 2a) can move left and right or tilt around a first axis (e.g., pitch) that intersects the optical axis with respect to the fixed unit. In addition, the OIS moving unit can move left and right or tilt around a second axis (e.g., yaw) that intersects the optical axis with respect to the fixed unit. For example, the first axis can be perpendicular to the optical axis direction, and the second axis can be perpendicular to the optical axis direction and the first axis. For example, the first axis can intersect the X-axis or the Y-axis. For example, the second axis can intersect the X-axis or the Y-axis. For example, the first and second axes can be perpendicular to each other. In another embodiment, for example, the first axis can be one of the X-axis and the Y-axis, and the second axis can be the other of the X-axis and the Y-axis.

[0077] For example, the OIS moving unit (100) may include an AF moving unit. In addition, the OIS moving unit may include an image sensor (810). The OIS moving unit (100) may include a circuit board (800) on which the image sensor (810) is placed. In addition, the OIS moving unit (100) may include a sensor base (270) on which at least a portion of the circuit board (800) is placed. In addition, the OIS moving unit may include a holder (140) coupled with the sensor base (270).

[0078] The OIS moving unit (100) may be expressed as a first moving unit (or first moving unit), and the AF moving unit may be expressed as a second moving unit (or second moving unit).

[0079] Also, for example, the OIS moving unit (100) may include a configuration that is arranged or coupled to at least one of the holder (140), the sensor base (270), and the circuit board (800). For example, the OIS moving unit (100) may include a filter (610) arranged to the holder (140). For example, the OIS moving unit (100) may include a support member (64) coupled to the sensor base (270). For example, the OIS moving unit (100) may include a magnetic body (33) coupled to the support member (64). For example, the OIS moving unit (100) may include at least one of the image sensor (810), sensors (170, 240), coils (120, 230), circuit elements (815), and control unit (830) arranged to the circuit board (800).

[0080] Additionally, the OIS moving unit (100) may include a moving module (or tilting module) and a support member (64). For example, the moving module (or tilting module) may include at least one of the remaining components of the OIS moving unit (100) described above, excluding the support member (64). The moving module may also be expressed as a “mover.”

[0081] For example, the moving module (or tilting module) may include a lens module (400) and an image sensor (810). Also, for example, the moving module (or tilting module) may include a sensor base (270). Also, for example, the moving module (or tilting module) may further include at least one of a holder (140) and a circuit board (800). For example, the moving module (or tilting module) may be tiltable about a first axis or a second axis.

[0082] The support member may support the OIS moving member relative to the fixed member, for example, the support member may include a tilting guide member (60). In other embodiments, for example, the support member may further include a cloud member (e.g., a ball member) or a sliding member (e.g., a shaft).

[0083] The bobbin (110) may be placed within the holder (140) to accommodate a lens or lens barrel. Alternatively, the bobbin (110) may be placed within the cover member (300). The bobbin (100) may be placed within the holder (140). The bobbin (110) may also be referred to as a “lens holder” or a “lens carrier.”

[0084] The bobbin (110) can move in the direction of the optical axis. For example, the bobbin (110) can move in a first direction (e.g., the Z-axis direction) by the electromagnetic interaction between the coil (120) and the magnet (130). The coil (120) and the magnet (130) can be an AF driving unit that moves or drives the AF moving unit. In addition, the bobbin (110) can be included in the OIS moving unit (100), and the bobbin (110) can be tilted or rotated by a preset angle based on the first axis or the second axis.

[0085] Referring to FIG. 5, the bobbin (110) may include an opening (101) for coupling with the lens module (400). The opening (101) may be a hole or hollow that penetrates the bobbin (110) in the direction of the optical axis. The shape of the opening (101) of the bobbin (110) may match the shape of the lens module (400) to be mounted or coupled, and may be, for example, circular, oval, or polygonal, but is not limited thereto. Although not illustrated in FIG. 5, the bobbin (110) may include at least one stopper disposed on at least one of the upper and lower surfaces. The stopper of the bobbin (110) may have a structure that protrudes in the first direction or the upper direction (or the lower direction) from the upper surface (or the lower surface) of the bobbin (110), and can prevent the upper surface (or the lower surface) of the bobbin (110) from directly colliding with the inner surface of the upper plate (301) of the cover member (300) (or the lower surface of the holder (140)).

[0086] The bobbin (110) may include a mounting portion (115) for mounting or arranging the magnet (130). For example, the mounting portion (115) may be a recessed groove formed from the outer surface of the bobbin (110). Referring to FIG. 6, the bobbin (110) may include a plurality of side surfaces (110A to 110D) or outer surfaces. For example, the bobbin (110) may include a first side surface (110A), a second side surface (110B), a third side surface (110C), and a fourth side surface (110D).

[0087] For example, the second side (110B) may face the first side (110A) or may be positioned opposite the first side (110A) with respect to the optical axis (OA). The third side (110C) and the fourth side (110D) may be positioned between the first side (110A) and the second side (110B). For example, the fourth side (110D) may face the third side (110C) or may be positioned opposite the third side (110C) with respect to the optical axis (OA). In FIG. 6, the bobbin (110) is illustrated as including four side surfaces, but in other embodiments, it may include three or five or more side surfaces.

[0088] For example, the mounting portion (115) may be formed on the first side (110A) of the bobbin. For example, the lower portion of the mounting portion (115) may be closed without being opened to the lower surface of the bobbin (110). Additionally, the upper portion of the mounting portion (115) may not be opened to the upper surface of the bobbin (110). In another embodiment, the mounting portion (115) may include an opening that is opened to at least one of the upper surface or lower surface of the bobbin.

[0089] The bobbin (110) may include a receiving portion (112) for receiving at least a portion of the cloud member (21). For example, at least a portion of the receiving portion (112) may be disposed on a first side (110A) of the bobbin (110). The receiving portion (112) may be a groove that is recessed from an outer surface of the bobbin (110) (e.g., the first side (110A)). The receiving portion (112) may also be expressed as a “receiving groove,” a “groove,” or a “guide groove.” A lubricant (e.g., grease) may be disposed within the receiving portion (112) of the bobbin (110) to reduce friction with the cloud member (21). For example, the bobbin (110) may include a first receiving portion (112A) for receiving a cloud member (21A) and a second receiving portion (112B) for receiving a cloud member (21B). For example, the mounting portion (115) may be positioned between the first receiving portion (112A) and the second receiving portion (112B).

[0090] For example, the first receiving portion (112A) (or the second receiving portion (112B)) may include an opening that opens to the upper surface of the bobbin (110). In another embodiment, the upper portion of the receiving portion (112A, 112B) may be closed without being opened to the upper surface of the bobbin (110). For example, the lower portion of the receiving portion (112A, 112B) may be closed without being opened to the lower surface of the bobbin (110). For example, the receiving portion (112) may be formed to extend in the direction of the optical axis. For example, the receiving portion (112) may extend in the direction of the optical axis so as to be formed between the upper and lower surfaces of the bobbin (110). For example, when viewed from above, the shape of the receiving portion (112) may be a triangle, but is not limited thereto, and may be a polygon (e.g., a square or a pentagon, etc.). Or, for example, when viewed from above, the receiving portion (112) may be in the shape of a 'V' or a 'U'.

[0091] The magnet (130) can be placed on the bobbin (110). The magnet (130) can be coupled to the bobbin (110) or fixed to the bobbin (110). For example, the magnet (130) can be placed on or coupled to the first side (110A) of the bobbin (110). For example, the magnet (130) can be placed within the mounting portion (115) of the bobbin (110) or coupled to the mounting portion (115). For example, the magnet (130) can be placed between the first cloud member (21A) and the second cloud member (21B). The shape of the magnet (130) can have a shape corresponding to the first side (110A) of the bobbin (110), for example, a rectangular parallelepiped shape. In another embodiment, for example, at least one of the ends of the magnet (130) may be tapered. For example, the magnet (130) may include a first side (13A) facing the coil (120) and a second side (13B) opposite the first side (13A). The first side (13A) of the magnet (130) may be exposed from the first side (110A) of the bobbin (110).

[0092] In addition, in order to enhance the electromagnetic force, the magnet (130) may be a four-pole magnet. For example, the magnet (130) may include two N poles and two S poles. For example, the magnet (130) may include a first magnet including a N pole and a S pole, a second magnet including a S pole and an N pole, and a partition wall disposed between the first magnet and the second magnet. In this case, the partition wall may include a section having almost no polarity, which is a substantially non-magnetic portion, and may be filled with air or made of a non-magnetic material, and may be expressed as a "neutral zone." For example, the first magnet and the second magnet may face each other in the optical axis direction, and the first magnet and the second magnet may be disposed to face each other with different polarities in the optical axis direction. In another embodiment, the magnet (130) may be a two-pole magnet having two different polarities and a naturally formed interface between the different polarities. For example, in another embodiment, the magnet (130) may include one north pole and one south pole. For example, the magnet (130) may be a magnet in which the north pole and the south pole are separated or arranged in the direction of the optical axis. In another embodiment, the magnet (130) may be a two-pole magnet in which the north pole and the south pole are separated in the direction perpendicular to the optical axis.

[0093] The holder (140) may be disposed on the inside of the cover member (300). The holder (140) may include a cavity for receiving the bobbin (110). The holder (140) may include an opening (30A) corresponding to the opening (101) of the bobbin (110). For example, the opening (30A) may be a through hole or hollow for exposing at least a portion of the bobbin (110) (or the lens module (400)). In addition, for example, the opening (30A) of the holder (140) may expose an imaging area of ​​the image sensor (810). The holder (140) may also be expressed as a “housing” instead. For example, the opening (30A) may be located in the center or a central region of the holder (140). For example, the opening (30A) of the holder (140) may be a through hole or hollow that penetrates the holder (140) in the direction of the optical axis. The opening (30A) of the holder (140) may have a shape corresponding to the shape of the bobbin (110), for example, a polygon (e.g., a square or an octagon) or a circle (or an oval), but is not limited thereto and may have various shapes.

[0094] The holder (140) may include a plurality of sides (41A to 41D). The holder (140) may include a corner positioned between two adjacent sides and connecting the two adjacent sides. The holder (140) may include a first side (41A) corresponding to or opposite a first side (110A) of the bobbin (110), a second side (41B) corresponding to or opposite a second side (110B) of the bobbin (110), a third side (41C) corresponding to or opposite a third side (110C) of the bobbin (110), and a fourth side (41D) corresponding to or opposite a fourth side (110D) of the bobbin (110). The first side (41A) (or the first side or the first outer side) of the holder (140) may be positioned opposite the second side (41B) (or the second side or the second outer side) of the holder (140) with respect to the optical axis, and the third side (41C) (or the third side or the third outer side) of the holder (140) may be positioned opposite the fourth side (41D) (or the fourth side or the fourth outer side) of the holder (140) with respect to the optical axis. Each of the first to fourth side portions (41A to 41D) of the holder (140) may be arranged parallel to a corresponding one of the side plates (302) of the cover member (300).

[0095] Referring to FIGS. 7A and 7B, the holder (140) may include a mounting portion (142A) for placing the coil (120). For example, the mounting portion (142A) may be placed or formed on the first side (41A) of the holder (140). For example, the mounting portion (142A) may be a through hole penetrating the first side (41A) of the holder (140). Since the mounting portion (142A) is in the form of a through hole, a part of the holder (140) may not be interposed between the coil (120) and the magnet (130), and thus, the electromagnetic force between the magnet (130) and the coil (120) may increase. In addition, since a part of the holder (140) is not interposed between the position sensor (170) and the magnet (130), the output of the position sensor (170) can be increased, and the sensitivity of the position sensor (170) can be improved. In addition, since a part of the holder (140) is not interposed between the coil (120) and the magnet (130), the size of the camera device can be reduced. In another embodiment, the mounting portion (142A) may be a groove shape that is recessed from the outer surface (or inner surface) of the first side portion (41A) of the holder (140).

[0096] Referring to FIG. 6, the holder (140) may include a groove (142) for placing at least a portion of the circuit board (800), for example, at least a portion of the second substrate (802). Since at least a portion of the second substrate (802) is placed within the groove (142) of the holder (140), the second substrate (802) and the magnetic body (82) may not protrude from the outer surface of the first side (41A) of the holder (140) or may not protrude excessively from the outer surface of the first side (41A). That is, the second substrate (802) and the magnetic body (82) may protrude less than the sum of the thicknesses of the second substrate (802) and the magnetic body (82) based on the outer surface of the first side (41A) of the holder (140). This may prevent the size of the camera device (200) from increasing in the direction perpendicular to the optical axis.

[0097] Referring to FIGS. 7A and 7B , the holder (140) may include a receiving portion (116) for arranging or receiving at least another portion of the cloud member (21). For example, at least a portion of the receiving portion (116) may be arranged on the first side (41A) of the holder (140). The receiving portion (116) may be a groove that is recessed from the inner surface of the holder (140) (e.g., the inner surface of the first side (41A)). The receiving portion (116) may also be expressed as a “receiving groove,” a “groove,” or a “guide groove.” At least a portion of the receiving portion (116) of the holder (140) may correspond to, face, or overlap with the receiving portion (112) of the bobbin (110).

[0098] The holder (140) may include a first receiving portion (116A) for receiving at least another portion of the first cloud member (21A; B1, B2) and a second receiving portion (116B) for receiving at least another portion of the second cloud member (21B; B3, B4). For example, the mounting portion (142A) of the holder (140) may be positioned between the first receiving portion (116A) and the second receiving portion (116B) of the holder (140). For example, the first receiving portion (116A) (or the second receiving portion (116B)) may include an opening that opens to the upper surface of the holder (140). In another embodiment, the upper portion of the receiving portion (116) may be closed without opening to the upper surface of the holder (140). For example, the lower portion of the receiving portion (116) may be closed without opening to the lower surface of the holder (140). For example, the receiving portion (116) may be formed to extend in the direction of the optical axis. For example, the receiving portion (116) may extend in the direction of the optical axis so as to be formed between the upper and lower surfaces of the holder (140). For example, when viewed from above, the shape of the receiving portion (116) of the holder (140) may be a triangle, but is not limited thereto, and may be a polygon (e.g., a square or a pentagon, etc.). Or, for example, when viewed from above, the receiving portion (116) may be a 'V' or 'U' shape. For example, when viewed in the direction of the optical axis or from above, the receiving portion (116) may face or overlap with the upper plate (301) of the cover member (300). For example, at least a portion of the upper plate (301) of the cover member (300) may cover the receiving portion (116).

[0099] The camera device (200) may include a cloud member (21) disposed between the bobbin (110) and the holder (140). The cloud member (21) may be alternatively expressed as a “ball member”, a “ball”, or a “ball bearing”. At least a portion of the cloud member (21) may be in contact with the bobbin (110) and the holder (140), and may support movement of the bobbin (110) in the optical axis direction by performing a rolling motion or a rotating motion between the bobbin (110) and the holder (140). When the bobbin (110) is moved in the optical axis direction, the cloud member (21) may reduce friction between the bobbin (110) and the holder (140). For the rolling motion or rotation of the cloud member (21), the bobbin (110) may be in contact with the cloud member (21) and may slide or slide in the optical axis direction.

[0100] For example, the cloud member (21) may be made of a metal material, ceramic, plastic, or resin material, but is not limited thereto. The cloud member (21) may have a circular or spherical shape and may have a diameter sufficient to support movement of the bobbin (110) in the optical axis direction. For example, the cloud member (21) may be arranged between the outer surface of the bobbin (110) and the inner surface of the holder (140). For example, the cloud member (21) may be arranged between the first side surface (110A) of the bobbin (110) and the first side portion (41A) of the holder (140). For example, the cloud member (21) may be arranged between the receiving portion (112) of the bobbin (110) and the receiving portion (116) of the holder (140).

The first cloud member (21A) may be disposed between the first receiving portion (112A) of the bobbin (110) and the first receiving portion (116A) of the holder (140). The second cloud member (21B) may be disposed between the second receiving portion (112B) of the bobbin (110) and the second receiving portion (116B) of the holder (140). For example, the first cloud member (21A) may include at least one ball. For example, the first cloud member (21A) may include a plurality of balls (B1, B2). The second cloud member (21B) may include at least one ball. For example, the second cloud member (21B) may include a plurality of balls (B3, B4). In another embodiment, each of the first cloud member (21A) and the second cloud member (21B) may include one ball.

[0102] In another embodiment, each of the first cloud member (21A) and the second cloud member (21B) may include three or more balls. For example, each of the first cloud member (21A) and the second cloud member (21B) may include a top ball located at the topmost position, a bottom ball located at the bottommost position, and at least one intermediate ball located between the top ball and the bottom ball. For example, the diameter of the top ball may be larger than the diameter of the intermediate ball, and the diameter of the lowest ball may be larger than the diameter of the intermediate ball. Also, for example, the diameters of the top ball and the lowest ball may be the same. In another embodiment, the diameters of the top ball, the lowest ball, and the intermediate ball may be the same. For example, each of the first cloud member (21A) and the second cloud member (21B) may include a first ball (top ball), a second ball (lowest ball), and a third ball (intermediate ball) arranged in the direction of the optical axis, and the diameter of the first ball may be larger than the diameter of the third ball.

In another embodiment, the diameter of the first ball may be greater than the diameter of the second ball. In another embodiment, the diameter of the first ball may be smaller than the diameter of the second ball. In another embodiment, the diameters of the first ball, the second ball, and the third ball may be the same.

[0103] When viewed from above, the coil (120) and the magnet (130) can be positioned between the first cloud member (21A) and the second cloud member (21B). As a result, when the bobbin (110) moves in the direction of the optical axis, the bobbin (110) can be prevented from tilting and moving, the cloud member (21) can stably support the bobbin (110), and the reliability of auto-focusing can be improved.

[0104] In another embodiment, each of the first cloud member (21A) and the second cloud member (21B) may be in the form of a shaft or roller. In another embodiment, a sliding member (e.g., a shaft) or a roller may be included instead of the ball member (21A, 21B).

[0105] The camera device (200) may include a magnet (130) and a magnetic body (82) that exerts an attractive force.

The second surface of the second substrate (802) may be the opposite surface of the first surface of the second substrate (802) that faces the magnet (130). The coil (120) may be disposed on the first surface of the second substrate (802). In another embodiment, the magnetic body (82) may be disposed on the housing (210), which is a fixed part.

[0106] An attractive force may be applied between the magnetic body (82) and the magnet (130) in a direction perpendicular to the optical axis (or a second direction). The magnetic body (82) may be made of a material that is attracted to a magnet. For example, the magnetic body (82) may be made of a metallic material. Or, for example, the magnetic body (82) may be made of a magnetic metallic material. Or, for example, the magnetic body (82) may be a magnet. The magnetic body (82) may also be expressed as a “yoke” or a “metal plate.”

[0107] Since the magnet (130) is placed on the bobbin (110) and the magnetic body (82) is placed on the holder (140), the bobbin (110) can be pulled toward the holder (140) where the magnetic body (82) is placed by the attractive force between the magnetic body (82) and the magnet (130). By the attractive force between the magnetic body (82) and the magnet (130), the bobbin (110) and the holder (140) can press the rolling member (21), and the bobbin (110) can be stably supported. The magnetic body (82) and the magnet (130) can be a “pressure unit” or a “pressure member”. By this pressing unit, when the bobbin (110) moves in the optical axis direction, contact can be maintained between the bobbin (110) and the rolling member (21) and between the holder (140) and the rolling member (21). That is, the cloud member (21) can stably support the bobbin (110) with respect to the holder (140) by the attractive force between the magnet (130) and the magnetic body (82).

For example, the mounting portions (274A, 274B) may be grooves recessed from the upper surface of the sensor base (270). For example, the sensor base (270) may include a first mounting portion (274A) for placing or settling the first coil unit (230A) and a second mounting portion (274B) for placing or settling the second coil unit (230B). For example, the first mounting portion (274A) may be formed to be adjacent to or in contact with one of the protrusions (216A to 216D) of the sensor base (270) (e.g., 216C). For example, the first mounting portion (274A) may be a groove formed on an upper surface of the sensor base (270) adjacent to the third protrusion (216C) of the sensor base (270). For example, the first mounting portion (274A) may include an opening that opens from an outer surface of a side portion (e.g., 51B, 51D) adjacent to the third protrusion (216C) of the sensor base (270). In another embodiment, the first mounting portion (274A) may be spaced apart from the outer surface of the side portion (e.g., 51B, 51D) of the sensor base (270) and may not include an opening that opens to the outer surface of the side portion (51B, 51D). For example, the second mounting portion (274B) may be formed to be adjacent to or in contact with another one of the protrusions (216A to 216D) of the sensor base (270) (e.g., 216D).For example, the second mounting portion (274B) may be a groove formed on the upper surface of the sensor base (270) adjacent to the fourth protrusion (216D) of the sensor base (270). For example, the second mounting portion (274B) may include an opening that opens from the outer surface of a side portion (e.g., 51B, 51C) adjacent to the fourth protrusion (216D) of the sensor base (270). In another embodiment, the second mounting portion (274B) may be spaced apart from the outer surface of the side portion (e.g., 51B, 51C) of the sensor base (270) and may not include an opening that opens to the outer surface of the side portion (51B, 51C). In another embodiment, the mounting portion (274) of the sensor base (270) may be formed at a position corresponding to a position where the coil (230) is disposed. In another embodiment, the mounting portions (274A, 274B) may be in the form of through holes. For example, at least one of the first and second mounting portions (274A, 274B) may be a hole or through hole penetrating the sensor base (270) in the optical axis direction. In this case, a part of the sensor base (270) may not be interposed between the coil (230) and the magnet (310), and thus, the electromagnetic force between the magnet (310) and the coil (230) may increase. In addition, since a part of the sensor base (270) may not be interposed between the position sensor (240) and the magnet (310), the output of the position sensor (240) may be increased, and the sensitivity of the position sensor (240) may be improved. In addition, since a part of the sensor base (270) is not interposed between the position sensor (240) and the magnet (310), the height of the camera device may be reduced. In another embodiment, the anchoring portion (274A, 274B) may be in the form of an escape portion that avoids spatial interference with the entire coil (230).

[0118] Referring to FIG. 7A, a groove (212A) may be formed in the protrusion (216) of the sensor base (270) into which at least a portion of the first substrate (801) of the circuit board (800) is inserted or placed. For example, a corner of the first substrate (801) may be inserted into or coupled with the groove (212A) of the protrusion (216) of the sensor base (270). For example, the groove (212A) may be formed on a side of the protrusion (216) facing the corner of the circuit board (800). In addition, a groove (83) may be formed in at least one corner of the circuit board (800) to be inserted into or coupled with the groove (212A) of the protrusion (216). The groove (212A) of the protrusion (216) of the sensor base (270) can serve as a defect guide for combining the first substrate (801) and the sensor base (270), and can serve to prevent the first substrate (801) from rotating or being separated from the sensor base (270).

[0119] The circuit board (800) may be placed, coupled, or fixed to the sensor base (270). For example, the circuit board (800) may be coupled to the sensor base (270) by an adhesive or a fixing member. The circuit board (800) may be placed, coupled, or fixed to the body (270A) of the sensor base (270). The circuit board (800) may include at least one of a rigid printed circuit board (Rigid PCB), a flexible printed circuit board (Flexible PCB), and a RigidFlexible printed circuit board (RigidFlexible PCB).

[0120] For example, the circuit board (800) may include a first substrate (801) (or “first region”) that is placed, coupled, or fixed to the sensor base (270). For example, the first substrate (801) may be placed, coupled, or fixed to the body (270A) of the sensor base (270). For example, a lower surface of the first substrate (801) may be coupled to an upper surface of the sensor base (270) (or an upper surface of the body (270A)). For example, a lower surface of the first substrate (801) may be coupled to an upper surface of the sensor base (270) or an upper surface of the body (270A) by an adhesive. The circuit board (800) may include a second substrate (802) (or “second region”) that is connected to the first substrate (801) and placed, coupled, or fixed to the holder (140). For example, the second substrate (802) may be positioned, coupled, or fixed to the first side (41A) of the holder (140). In FIG. 7A, the circuit board (800) includes one second substrate, but in other embodiments, the circuit board (800) may include a plurality of second substrates positioned on at least one of the sides of the holder (140). For example, the second substrate (802) may be connected to the first side of the first substrate (801). For example, the second substrate (802) may be bent from the first side of the first substrate (801) toward the first side (41A) of the holder (140). For example, the second substrate (802) may extend upward from the first substrate (801).

For example, the third substrate (803) may be a rigid printed circuit board. For example, the fourth substrate (804) may be a flexible printed circuit board. For example, the rigid printed circuit board may include a plurality of conductive layers (or circuit patterns) spaced apart from each other in the optical axis direction, and an insulating layer arranged between two adjacent conductive layers among the plurality of conductive layers. For example, the flexible circuit board may include one conductive layer (or circuit pattern), a first insulating layer arranged on the conductive layer, and a second insulating layer arranged under the conductive layer. In another embodiment, the flexible circuit board may include a first conductive layer, a second conductive layer, and a first insulating layer disposed between the first and second conductive layers, a second insulating layer disposed on the first conductive layer, and a third insulating layer disposed below the second conductive layer.

[0122] The image sensor (810) may be placed on the first substrate (801). The image sensor (810) may be placed to correspond to, face, or overlap the lens module (400) or / and the filter (610) in the optical axis direction. For example, the image sensor (810) may be placed on the upper surface of the circuit board (800). For example, the image sensor (810) may be placed on the upper surface of the first substrate (801).

[0123] The image sensor (810) may include a sensor surface for detecting light. For example, the sensor surface may include an imaging area. 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 imaging area may correspond to, face, or overlap the lens module (400) and / or the filter (610) in the optical axis direction. The image sensor (810) may be conductively or electrically connected to the first substrate (801). For example, the image sensor (810) may be conductively connected to the first substrate (801) by a conductive member, such as a wire (not shown). For example, the first substrate (801) of the circuit board (800) may include at least one pad or terminal (not shown) that is electrically connected to a wire that is electrically connected to the image sensor (810). For example, pads or terminals that are conductively connected to wires may be placed on the upper surface of the first substrate (801).

For example, the circuit element (815) may include at least one of a passive element (e.g., a capacitor or a resistor), an active element (e.g., a sensor, a memory, a driver IC), or a circuit pattern. For example, in order to avoid spatial interference with the image sensor (810), the circuit element (815) may be disposed between the image sensor (810) and an edge (e.g., a side) of the first substrate (801).

[0125] The camera device (200) may include a control unit (830) disposed on a circuit board (800). For example, the control unit (830) may be a driver IC. For example, the control unit (830) may be disposed on a first substrate (801). For example, the control unit (830) may be disposed under the first substrate (801). For example, the control unit (830) may be disposed, coupled, or fixed to a lower surface of the first substrate (801). For example, the control unit (830) may be conductively or electrically connected to the first substrate (801). For example, the control unit (830) may be conductively or electrically connected to the coil (120) and may supply a driving signal to the first coil (120). The control unit (830) can be conductively or electrically connected to the coil units (230A, 230B) of the coil (230), and can supply a first driving signal to the first coil unit (230A) and a second driving signal to the second coil unit (230B).

[0126] The control unit (830) may be conductively or electrically connected to the position sensor (170). In addition, the control unit (830) may be conductively or electrically connected to the position sensor (240). For example, the control unit (830) may receive an output signal of the position sensor (170) and control a driving signal (e.g., driving current) supplied to the coil (120) using the output signal of the position sensor (170). For example, the control unit (830) may receive an output signal of the position sensor (240) and control a driving signal (e.g., driving current) supplied to the coil (230) using the output signal of the position sensor (240). For example, the control unit (830) can receive an output signal of the first sensor (240A) and control a first driving signal (e.g., a first driving current) supplied to the first coil unit (230A) using the output signal of the first sensor (240A). In addition, the control unit (830) can receive an output signal of the second sensor (240B) and control a second driving signal (e.g., a second driving current) supplied to the second coil unit (230B) using the output signal of the second sensor (240B).

[0127] The coils (120, 230) may be placed, coupled, or fixed to the circuit board (800). For example, the coil (120) may be conductively or electrically connected to the circuit board (800) (e.g., the second substrate (802)) by a conductive adhesive or solder. For example, the coil (230) may be conductively or electrically connected to the circuit board (800) (e.g., the first substrate (801)) by a conductive adhesive or solder.

[0128] The first coil unit (230A) and the second coil unit (230B) may be disposed or coupled to the first substrate (801) and may be conductively or electrically connected to the first substrate (801). Referring to FIG. 7B, for example, the first coil unit (230A) and the second coil unit (230B) may be disposed, coupled, or fixed to the lower surface of the first substrate (801). For example, the first coil unit (230A) and the second coil unit (230B) may be disposed between the first substrate (801) and the sensor base (270). For example, the first and second coil units (230A, 230B) may be disposed adjacent to two adjacent corners among the four corners of the first substrate (801). For example, for diagonal driving, the first coil unit (230A) may be positioned adjacent to one corner of the first substrate (801) corresponding to the protrusion (216C) of the sensor base (270) (or one corner of the sensor base (270)), and the second coil unit (230B) may be positioned adjacent to the other corner of the first substrate (801) corresponding to the protrusion (216D) of the sensor base (270) (or one other corner of the sensor base (270). For example, the first coil unit (230A) may be positioned adjacent to the protrusion (216C) of the sensor base (270), and the second coil unit (230B) may be positioned adjacent to the protrusion (216D) of the sensor base (270). In another embodiment, the first and second coil units (230A, 230B) may be arranged adjacent to two adjacent sides among the four sides of the first substrate (801).

[0129] The coil (120) can move the AF moving part (e.g., bobbin) in the optical axis direction by interaction with the magnet (130). The coil (120) may be an AF drive coil for AF operation. The coil (120) may be placed in the holder (140). The coil (120) may be placed to correspond to, face, or overlap the magnet (130) in a direction perpendicular to the optical axis. For example, the coil (120) may be placed in the holder (140) to correspond to, face, or overlap the magnet (130) in a second direction (e.g., X-axis direction) or in a direction from the first side (41A) of the holder (140) to the second side (41B). For example, the coil (120) may be placed in the first side (41A) of the housing (130). The coil (120) may be placed within the mounting portion (142A) of the holder (140). For example, the coil (120) may include a hollow portion or a hole. For example, the coil (120) may have a ring shape or a closed curve shape. For example, the coil (120) may have a ring shape wound around a straight line that is perpendicular to the optical axis (OA) and perpendicular to the outer surface of the first side (41A) of the holder (140). For example, the coil (120) may have a ring shape in which the length in the horizontal direction (or the third direction) is longer than the length in the vertical direction (or the optical axis direction).

[0130] A driving signal may be applied to the coil (120) to generate an electromagnetic force by electromagnetic interaction with the magnet (130). For example, the driving signal may be applied to the coil (120) from the circuit board (800) or the control unit (830). At this time, the driving signal supplied to the coil (120) may be a direct current, and may be in the form of voltage or current. Or, in another embodiment, for example, the driving signal provided to the coil (120) may include at least one of a direct current signal and an alternating current signal. The coil (120) supplied with the driving signal may electromagnetically interact with the magnet (130) arranged on the bobbin (110), and the AF moving unit may move in the first direction by the electromagnetic force resulting from the electromagnetic interaction between the coil (120) and the magnet (130). By controlling the size and / or direction of the driving signal (e.g., driving current) by the control unit (830), the movement of the AF moving unit in the first direction can be controlled, thereby performing the auto-focusing function.

[0131] For AF feedback driving, the camera device (200) may include a position sensor (170). The position sensor (170) may detect the position or displacement of the bobbin (110) in the optical axis direction. For example, the position sensor (170) may detect a magnet (130) disposed on the bobbin (110). In another embodiment, a sensing magnet opposite to the position sensor (170) may be disposed on the bobbin separately from the magnet (130), and the position sensor (170) may detect the displacement of the bobbin by detecting the sensing magnet or the magnetic field of the sensing magnet.

[0132] For example, the position sensor (170) may be placed in the holder (140). For example, the position sensor (170) may be placed on the first side (41A) of the holder (140). For example, the position sensor (170) may be placed within the mounting portion (142A) of the holder (140). For example, the position sensor (170) may be placed within the hollow portion of the coil (120). In another embodiment, the position sensor (170) may be placed outside the hollow portion of the coil (120). For example, the position sensor (170) may be coupled to the circuit board (800). For example, the position sensor (170) may be coupled to the circuit board (800) by a conductive adhesive or solder. For example, the position sensor (170) may be conductively or electrically connected to the second substrate (802). For example, the position sensor (170) may be conductively or electrically connected to the second substrate (802) by a conductive adhesive or solder. For example, the position sensor (170) may be placed, coupled, or fixed to the first surface of the second substrate (802). For example, the position sensor (170) may correspond to, face, or overlap the magnet (130) in a direction perpendicular to the optical axis or in the second direction.

[0133] The position sensor (170) can detect the displacement of the bobbin (110) in the optical axis direction. For example, the position sensor (170) can detect the magnetic field or the strength of the magnetic field of the magnet (130) mounted on the bobbin (110) according to the movement of the bobbin (110) and output an output signal. For example, the position sensor (170) may be a Hall sensor. In this case, the position sensor (170) may include two input terminals to which a driving signal is applied and two output terminals to which an output signal is output. The circuit board (800) may be conductively or electrically connected to the two input terminals and the two output terminals of the position sensor (170). The circuit board (800) or the control unit (830) can supply a driving signal to two input terminals of the position sensor (170), and the output signal output from the two output terminals of the position sensor (170) can be transmitted to the circuit board (800) or the control unit (830).

[0134] In another embodiment, the position sensor (170) may be implemented in the form of a driver IC including a Hall sensor. For example, when the position sensor (170) is a driver IC including a Hall sensor, the position sensor (170) may transmit and receive data with the outside using data communication using a protocol, for example, I2C communication. For example, when the position sensor (170) is a driver IC including a Hall sensor, the position sensor (170) may include first and second terminals for inputting a power or drive signal, a third terminal for a clock signal, a fourth terminal for a data signal, and fifth and sixth terminals for supplying a drive signal to the coil (120). The first to sixth terminals of the position sensor (170) may be conductively or electrically connected to the circuit board (800).

[0135] The coil (230) can tilt the OIS moving part about the first axis or the second axis or rotate it by a preset angle by interaction with the magnet (310) placed in the housing (210), which is a fixed part. The coil (230) may be an OIS driving coil for OIS operation. The coil (230) may be opposed to, corresponding to, or overlapped with the magnet (310) in the optical axis direction. The coil (230) may include a first coil unit (230A) corresponding to, corresponding to, or overlapping with the first magnet unit (310A) in the optical axis direction, and a second coil unit (230B) corresponding to, corresponding to, or overlapping with the second magnet unit (310B) in the optical axis direction. For example, the coil (230) may not overlap with the magnet (310) in a direction perpendicular to the optical axis.

[0136] For example, the coil (230) may be positioned below the coil (120). For example, the first coil unit (230A) may be positioned within the first mounting portion (274A) of the sensor base (270), and the second coil unit (230B) may be positioned within the second mounting portion (274B) of the sensor base (270). For example, each of the first and second coil units (230A, 230B) may include a hollow or a hole. For example, each of the first and second coil units (230A, 230B) may have a ring shape or a closed curve shape. For example, each of the first coil unit (230A) and the second coil unit (230B) may have a ring shape that is wound around a straight line that is parallel to the optical axis (OA) and perpendicular to the upper surface of the sensor base (270) or the upper surface of the body (270A).

[0137] For example, referring to FIG. 16A, the first coil unit (230A) may be a ring shape in which the length in the horizontal direction (or the direction parallel to the second axis) is longer than the length in the vertical direction (or the direction parallel to the first axis). For example, the second coil unit (230B) may be a ring shape in which the length in the vertical direction (e.g., the direction parallel to the first axis) is longer than the length in the horizontal direction (or the direction parallel to the second axis).

[0138] For OIS feedback driving, the camera device (200) may include a position sensor (240). The position sensor (240) may detect displacement or angular displacement of the OIS moving unit (100) according to tilting or rotation of the OIS moving unit (100). The position sensor (240) may detect a magnetic field of the magnet (310). For example, the position sensor (240) may include a first sensor (240A) and a second sensor (240B). For example, at least a portion of the first sensor (240A) may correspond to, face, or overlap with the first magnet unit (310A) in the optical axis direction. For example, the center of the first sensor (240A) may overlap with the first magnet unit (310A) in the optical axis direction. For example, the first sensor (240A) can detect the first magnet unit (310A) (or the magnetic field of the first magnet unit (310A)). For example, the first sensor (240A) can detect the tilted angle of the OIS moving part (100) with respect to the second axis. In another embodiment, the first sensor (240A) may not overlap the first and second magnet units (310A, 310B) in the optical axis direction.

[0139] At least a portion of the second sensor (240B) may correspond to, face, or overlap with the second magnet unit (310B) in the optical axis direction. For example, the center of the second sensor (240B) may overlap with the second magnet unit (310B) in the optical axis direction. For example, the second sensor (240B) may detect the second magnet unit (310B) (or the magnetic field of the second magnet unit (310B)). For example, the second sensor (240B) may detect the tilted angle of the OIS moving part (100) with respect to the first axis. In other embodiments, the second sensor (240B) may not overlap with the second magnet unit (310B) in the optical axis direction.

[0140] For example, the first and second sensors (240A, 240B) may be placed, coupled, or fixed to the first substrate (801) of the circuit board (800). For example, the first and second sensors (240A, 240B) may be conductively or electrically connected to the first substrate (801). For example, the first sensor (240A) may be placed within the hollow (or hole) of the first coil unit (230A), and the second sensor (240B) may be placed within the hollow (or hole) of the second coil unit (230B). In another embodiment, the first sensor (240A) may be placed outside the hollow (or hole) of the first coil unit (230A), and the second sensor (240B) may be placed outside the hollow (or hole) of the second coil unit (230B). 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. For example, the first and second input terminals and the first and second output terminals of the first sensor (240A) may be conductively or electrically connected to the first substrate (801), and the first and second input terminals and the first and second output terminals of the second sensor (240B) may be conductively or electrically connected to the first substrate (801). For example, the first substrate (801) or the control unit (830) may supply or apply a first drive signal to the first and second input terminals of the first sensor (240A). The first sensor (240A) may output a first output signal, and the first output signal may be transmitted to the first substrate (801) or the control unit (830). The first output signal can be output to the first and second output terminals of the first sensor (240A). For example, the first substrate (801) or the control unit (830) can supply or apply the second drive signal to the first and second input terminals of the second sensor (240B). The second sensor (240B) can output the second output signal, and the second output signal can be transmitted to the first substrate (801) or the control unit (830).The second output signal can be output to the first and second output terminals of the second sensor (240B).

[0141] The control unit (830) can control the first driving signal supplied to the first coil unit (230A) and the second driving signal supplied to the second coil unit (230B) using the first output signal of the first sensor (240A) and the output signal of the second sensor (240B).

[0142] In another embodiment, each of the first sensor (240A) and the second sensor (240B) may be a driver IC including a Hall sensor. The description of the embodiment in which the position sensor (170) is a driver IC including a Hall sensor may be applied or analogically applied to the embodiment in which the first and second sensors (240A, 240B) are driver ICs including Hall sensors.

[0143] Referring to FIGS. 10A and 10B , the housing (210) may include a cavity for accommodating the OIS moving unit (100). For example, the housing (210) may have a shape corresponding to the OIS moving unit (100), for example, the holder (140) or the sensor base (270), for example, a polygon (e.g., a square or an octagon) or a circle (or an oval), but is not limited thereto and may have various shapes. The housing (210) may be expressed as a “base” or a “frame”.

[0144] The housing (210) may include a plurality of sides (71A to 71D) corresponding to the sides (41A to 41D) of the holder (140) or the sides (51A to 51D) of the sensor base (270). The housing (210) may include a corner positioned between two adjacent sides. In addition, the housing (210) may include a lower portion (42) (or lower plate) positioned below the sides (71A to 71D). The lower portion (42) may be connected to the lower sides of the sides (71A to 71D). For example, the lower portion (42) may be expressed as a “bottom portion,” a “bottom surface,” or a “body.” For example, the sides (71A to 71D) may protrude upward from the lower portion (42).

[0145] The housing (210) may include a first side (71A) corresponding to, opposite to, or overlapping the first side (41A) of the holder (140), a second side (71B) corresponding to, opposite to, or overlapping the second side (41B) of the holder (140), a third side (71C) corresponding to, opposite to, or overlapping the third side (41C) of the holder (140), and a fourth side (71D) corresponding to, opposite to, or overlapping the fourth side (41D) of the holder (140).

In another embodiment, the first bend portion (804D) and the second bend portion (804E) may be rounded. In another embodiment, the internal angle between the first portion (804A) and the second portion (804B) may be acute or obtuse. The first bend portion (804D) and the second bend portion (804E) can prevent the length of the camera device (200) from increasing in a direction perpendicular to the optical axis direction. In addition, since the first bending portion (804D) and the second bending portion (804E) are positioned between the upper surface of the camera device (200) (e.g., the upper surface of the cover member (300)) and the lower surface of the camera device (200) (e.g., the lower surface of the housing (210)), the length of the camera device (200) can be prevented from increasing in the optical axis direction, thereby enabling miniaturization of the camera device. For example, the third portion (804C) may be in the form of a plate or plane perpendicular to the optical axis. For example, the third portion (804C) may include a meandering shape or a serpentine shape. For example, the third portion (804C) may include at least one bent or curved region.For example, the folded or curved region of the third portion (804C) may be folded in a second direction or a third direction perpendicular to the optical axis. Alternatively, the folded or curved region of the third portion (804C) may extend in a direction perpendicular to the optical axis. For example, when viewed from above, the third portion (804C) may include a region having a U- or V-shape. For example, the third portion (804C) may be spaced apart from the housing (210). For example, the third portion (804C) may be spaced apart from the protrusion (215) of the housing (210). In other embodiments, for example, at least a portion of the third portion (804C) may be in contact with the protrusion (215) of the housing (210).

[0172] At least a portion of the second portion (804B) of the fourth substrate (804) may be disposed within the protrusion (215) of the housing (210). At least a portion of the second portion (804B) of the fourth substrate (804) may be disposed within the groove (16A) of the protrusion (215) of the housing (210). For example, at least a portion of the first portion (804A) of the fourth substrate (804) may pass through the opening (16B) of the groove (16A) of the protrusion (215) and may be disposed within the groove (16A) of the protrusion (215) of the housing (140). The second portion (804B) may be disposed within the groove (16A) of the protrusion (215) of the housing (140). The third portion (804C) of the fourth substrate (804) may be positioned outside the protrusion (215) of the housing (210). For example, the third portion (804C) of the fourth substrate (804) may be positioned above the protrusion (215) of the housing (210). The lower surface of the third portion (804C) of the fourth substrate (804) may be positioned above the upper surface of the protrusion (215) of the housing (210).

[0173] Referring to FIG. 7A, the sensor base (270) may include a groove (273) formed at a location where the fourth substrate (804) and the first substrate (801) meet or are connected, for example, corresponding to the first portion (804A) of the fourth substrate (804). The groove (273) may be positioned adjacent to or in contact with the outer surface of the fourth side (51D) of the sensor base (270) on which the fourth substrate (804) is positioned. The groove (273) may serve to prevent the first portion (804A) of the fourth substrate (804) from being damaged by friction with the sensor base (270).

[0174] The connector (805) can be coupled or connected to another connector or external device outside of the camera device (200). The connector (805) connected to another external connector may correspond to a fixed part that does not move when the OIS is driven. That is, one end of the fourth substrate (804) may be coupled to an OIS moving part (e.g., the first substrate (801) of the circuit board (800)), and the other end of the fourth substrate (804) may be coupled to a fixed part (e.g., the connector (805)). Since the third part (804C) of the fourth substrate (804) includes at least one bent or curved area, it can flexibly support the camera device (200) or the OIS moving part and serve to alleviate external impact. That is, the third part (804C) of the fourth substrate (804) may serve as a spring that alleviates impact. In addition, since the third part (804C) of the fourth substrate (804) can play a role of elastically supporting the OIS moving part (100), the driving force or driving power required for driving the OIS can be reduced.

[0175] Referring to FIG. 11, the camera device (200) may include a reinforcing member (70) disposed, coupled, or attached to at least a portion of the fourth substrate (804). The reinforcing member (70) may be disposed, coupled, or attached to at least one of the first portion (804A) and the second portion (804B) of the fourth substrate (804). For example, the reinforcing member (70) may be disposed, coupled, or attached to at least a portion of the first portion (804A) and at least a portion of the second portion (804B) of the fourth substrate (804). For example, the reinforcing member (70) may be disposed, coupled, or attached to a lower surface of the first portion (804A) and a lower surface of the second portion (804B) of the fourth substrate (804). For example, the reinforcing member (70) may include a first region (70A) that is disposed, coupled, or attached to a first portion (804A) and a second region (70B) that is disposed, coupled, or attached to a second portion (804B). The second region (70B) may be bent upward from the first region (70A). For example, a bend may be formed between the first region (70A) and the second region (70B). For example, the area of ​​the second region (70B) may be larger than the area of ​​the first region (70A). In other embodiments, the two may be the same, or the area of ​​the former (70B) may be smaller than the area of ​​the latter (70A). For example, the reinforcing member (70) may be spaced apart from the third region (804C) of the fourth substrate (804). For example, the second region (70B) of the reinforcing member (70) may be spaced apart from the third portion (804C) of the fourth substrate (804). In another embodiment, at least a portion of the second region (70B) of the reinforcing member (70) may be in contact with the third portion (804C) of the fourth substrate (804).

[0176] In another embodiment, the reinforcing member (70) may be positioned, coupled, or attached to the upper surface of the first portion (804A) and the upper surface of the second portion (804B) of the fourth substrate (804). For example, in another embodiment, the reinforcing member (70) may include a first region positioned on the upper surface of the first portion (804A) of the fourth substrate (804) and a second region positioned on the upper surface of the second portion (804B) of the fourth substrate (804). In yet another embodiment, the reinforcing member (70) may be positioned, coupled, or attached to at least a portion of the second portion (804B) and at least a portion of the third portion (804C) of the fourth substrate (804).

[0177] The reinforcing member (70) can prevent the fourth substrate (804) from being damaged, deformed, or broken due to impact or external force. In addition, the reinforcing member (70) can serve to suppress the shape of the fourth substrate (804) from being deformed and restored due to the force applied to the fourth substrate (804) by the tilting of the OIS moving part (100). For example, the reinforcing member (70) can include at least one of a metal material or an injection-molded material. For example, the reinforcing member (70) can be arranged inside the groove (16A) of the protrusion (215) of the housing (210). For example, at least a portion of the reinforcing member (70) can be in contact with the groove (16A) of the protrusion (215) of the housing (210). For example, the reinforcing member (70) may not be coupled to the housing (210) (e.g., the protrusion (215)). In another embodiment, for example, the reinforcing member (70) may be joined to the housing (210) (e.g., the protrusion (215)) by an adhesive.

[0178] The reinforcing member (70) may include an opening (73). The opening (73) of the reinforcing member (70) may open or expose at least a portion of the fourth substrate (804) of the circuit board (800). For example, the opening (73) may open or expose at least a portion of a first portion (804A) (or “first region”) and a second portion (804B) (or “second region”) of the fourth substrate (804). The opening (73) of the reinforcing member (70) may be a hole, a through hole, or a hollow. The opening (73) may be formed in at least one of the first region (70A) and the second region (70A) of the reinforcing member (70). For example, the opening (73) may be formed in the first region (70A) and the second region (70A) of the reinforcing member (70). In addition, the opening (73) may open or expose at least a portion of the first bending portion (804D). In another embodiment, the opening (73) may be formed in only one of the first region (70A) and the second region (70A) of the reinforcing member (70). In another embodiment, the opening (73) may not expose the first bending portion (804D). The elastic modulus of the second substrate (802) of the circuit board (800) coupled to the reinforcing member (70) may be reduced by the opening (73), thereby facilitating movement of the OIS moving portion during OIS driving. That is, the elastic force of the circuit board (800) supporting the OIS moving portion, for example, the second substrate (802), may be reduced by the opening (73), thereby facilitating OIS driving with less driving force and reducing power consumption. At this time, the driving force may be a force resulting from the interaction between the coil (230) and the magnet (310). In another embodiment, the opening (73) of Fig. 11 may not be formed in the reinforcing member (70).

[0179] Referring to FIG. 1, FIG. 10A and FIG. 10B, the movement restraining member (80) can be coupled with the protrusion (215) of the housing (210). For example, the movement restraining member (80) can be coupled with the engaging grooves (215A, 215B) of the protrusion (215) of the housing (210). Referring to FIG. 3, at least a portion of the second portion (804B) of the fourth substrate (804) can be disposed between the movement restraining member (80) and the inner surface of the protrusion (215) of the housing (210). For example, at least a portion of the reinforcing member (70) can be disposed between the movement restraining member (80) and the inner surface of the protrusion (215) of the housing (210). The movement restraining member (80) can be spaced apart from the circuit board (800) in the second direction (X-axis direction) or the third direction (Y-axis direction). For example, the movement restraining member (80) may be spaced apart from the circuit board (800) in the direction of the optical axis or in a direction perpendicular to the optical axis. That is, the movement restraining member (80) may serve to maintain the shape of the bending members (804D, 804E) of the fourth substrate (804), which is a flexible substrate. For example, the movement restraining member (80) may be an injection-molded product made of a non-magnetic material or resin. In another embodiment, the movement restraining member (80) may be in contact with at least a portion of the fourth substrate (804) of the circuit board (800). At least a portion of the second portion (804B) of the fourth substrate (804) disposed in the groove (16A) of the protrusion (215) may be restricted from moving or moving by the movement restraining member (800), and the second portion (804B) may be restrained or prevented from moving out of the groove (16A) of the protrusion (215). This can suppress or prevent the OIS moving part from being affected by the restoring force of the fourth substrate (804) during OIS operation, thereby enabling accurate OIS operation and improving the reliability of OIS operation. The movement suppression part (80) can also be expressed as a “clamp”.

[0180] The cover member (300) can accommodate the OIS moving unit. The cover member (300) can form a receiving space together with the housing (210), and the OIS moving unit can be arranged within the receiving space. For example, the cover member (300) can have a box shape with an open bottom. For example, the cover member (300) can include a top plate (301) and a side plate (302) connected to the top plate (301). The lower end of the side plate (302) of the cover member (300) can be coupled to the housing (210). The shape of the top plate (302) of the cover member (300) can be polygonal (e.g., square or octagonal) or circular. The top plate (302) of the cover member (300) can include an opening (303) for exposing a lens (not shown) to external light. The opening (303) may be a through hole that penetrates the upper plate (302) of the cover member (300) in the direction of the optical axis. For example, the cover member (300) may have multiple side plates. The material of the cover member (300) may be a non-magnetic substance. In another embodiment, the cover member (300) may be a magnetic substance. For example, the material of the cover member (300) may be an injection-molded product such as resin or a metal material.

[0181] Referring to FIGS. 1 and 2A, the cover member (300) may include an opening (304) positioned or formed in the side plate (302) to avoid spatial interference with the protrusion (215) of the housing (210). For example, the protrusion (216) of the housing (210) may pass through the opening (304) of the cover member (300) and protrude from the side plate (302) of the cover member (300). The cover member (300) may include a protrusion (305) positioned over the opening (304) and protruding from the side plate (302). For example, the protrusion (305) may be plate-shaped. For example, the protrusion (305) of the cover member (300) may be positioned on the protrusion (215) of the housing (210). For example, the protrusion (305) may be disposed above the groove (16A) of the protrusion (215) of the housing (210). For example, the protrusion (305) may be disposed above the movement-inhibiting portion (80). For example, the protrusion (305) may overlap the movement-inhibiting portion (80) in the optical axis direction. In addition, for example, the protrusion (305) may overlap the first part (804A) of the fourth substrate (804) in the optical axis direction. The protrusion (305) may suppress or prevent the movement-inhibiting portion (80) from being detached, and may protect the movement-inhibiting portion (80) and the fourth substrate (804) from impact.

[0182] Referring to FIG. 4g, the cover member (300) may include a protrusion (311) protruding from the upper plate (301). At this time, the protrusion (311) of the cover member (300) may protrude from the inner surface of the upper plate (301) of the cover member (300) toward the bobbin (110) or the cloud member (21). For example, the protrusion (311) of the cover member (300) may face or overlap with the receiving portion (116) of the bobbin (110) in the optical axis direction. At least a portion of the protrusion (311) of the cover member (300) may be inserted or arranged within the receiving portion (116) of the bobbin (110). The protrusion (311) of the cover member (300) may be arranged on the cloud member (21). For example, the cover member (300) may include a first protrusion (311A) corresponding to, opposite to, or overlapping with the first receiving portion (116A) of the first cloud member (21A) or the bobbin (110). For example, the cover member (300) may include a second protrusion (311B) corresponding to, opposite to, or overlapping with the second receiving portion (116B) of the second cloud member (21B) or the bobbin (110). For example, the protrusion (311) of the cover member (300) may include a groove that is recessed from the upper surface of the upper plate (301) of the cover member (330). In other embodiments, the protrusion of the cover member (300) may not include a groove. By providing the protrusion (311) on the cover member (300), the embodiment can prevent the cloud member (21) from being separated from the receiving portion (116) of the bobbin (110). In addition, the protrusion (311) of the cover member (300) can also function as a stopper to prevent the bobbin (110) from moving any further in the upper direction within a limited range.

[0183] The following describes the support.

[0184] The support member may be positioned between the fixed member and the OIS moving member (100). The support member may be positioned between at least a portion of the holder (140) and the housing (210), and may support the holder (140) with respect to the housing (210). The support member may include a tilting guide member (60) positioned between the OIS moving member (e.g., the holder (140)) and the fixed member (e.g., the housing (210)).

[0185] The tilting guide unit (60) can guide the tilting of the OIS moving unit (100). The tilting guide unit (60) can also be expressed as a driving frame, a tilting plate, a “mover,” a “mover frame,” a “tilting frame,” a “moving plate,” a “frame,” a “tilting plate,” a “moving frame,” or a “support frame.” The tilting guide unit (60) can tilt about a first axis or a second axis or can tilt by a preset angle.

[0186] The tilting guide part (60) can be arranged between at least a portion (14) of the holder (140) and the side of the housing (210). The tilting guide part (60) can be arranged between at least a portion (14) of the holder (140) and the side portions (71A to 71C) of the housing (210). The tilting guide part (60) can be arranged between the upper plate (301) of the cover member (300) and the side of the housing (210).

[0187] At least a portion (14) of the holder (140) may face or overlap with the tilting guide portion (60) in the optical axis direction. At least a portion (14) of the holder (140) may be a protrusion protruding from an outer surface of the holder (140). The holder (140) may include a first protrusion (14A) and a second protrusion (14B). The first protrusion (14A) and the second protrusion (14B) may be positioned opposite to each other in the second-axis direction. The first protrusion (14A) may protrude from one of the two corners of the holder (140) that are positioned opposite to each other in the second-axis direction, and the second protrusion (14B) may protrude from the other of the two corners of the holder (140) that are positioned opposite to each other in the second-axis direction. The first protrusion (14A) and the second protrusion (14B) may protrude in opposite directions.

[0188] Referring to FIG. 3, the tilting guide part (60) may be positioned below the protrusion (14) of the holder (140). The tilting guide part (60) may be positioned higher than the upper surface of the side of the housing (140). The tilting guide part (60) may overlap the side (41A to 41D) of the holder (140) in a direction perpendicular to the optical axis. The tilting guide part (60) does not overlap with the image sensor (810) or the circuit board (800) in the optical axis direction. The tilting guide part (60) may not overlap with the housing (210) and the image sensor (810) in a direction perpendicular to the optical axis. The tilting guide part (60) may be positioned higher than the image sensor (810) and the housing (210) in the optical axis direction.

[0189] The length of the tilting guide part (60) in the optical axis direction is smaller than the length of the side parts (41A to 41C) of the holder (140) in the optical axis direction. Since the tilting guide part (60) is arranged on the outside of the side parts (41A to 41C) of the holder (140), the height of the camera device (200) in the optical axis direction can be reduced.

[0190] Referring to FIGS. 9A, 9B, and 12, the tilting guide portion (60) may be in the form of a line frame. The tilting guide portion (60) may be arranged to surround three of the side portions (41A to 41D) of the holder (140). For example, when viewed from above, the shape of the tilting guide portion (60) may be a “ㄷ” shape. The length of the tilting guide portion (60) in the optical axis direction may be smaller than the length in the horizontal direction (e.g., the horizontal direction or the vertical direction) perpendicular to the optical axis of the tilting guide portion (60).

[0191] The tilting guide part (60) may include a first guide part (60A) disposed on a first side (71A) of the housing (210), a second guide part (60B) disposed on a second side (71B) of the housing (210), and a third guide part (60C) disposed on a third side (71C) of the housing (210). The third guide part (60C) may connect the first guide part (60A) and the second guide part (60B).

[0192] The first guide portion (60A) may overlap with the first side portion (71A) of the housing (210) in the direction of the optical axis. The second guide portion (60B) may overlap with the second side portion (71B) of the housing (210) in the direction of the optical axis. The third guide portion (60C) may overlap with the third side portion (71C) of the housing (210) in the direction of the optical axis.

[0193] At least a portion of the circuit board (800) (e.g., the fourth substrate (804)) may be disposed on the fourth side (71D) of the housing (210). At least a portion of the circuit board (800) (e.g., the fourth substrate (804)) may overlap the fourth side (71D) of the housing (210) in the optical axis direction. Accordingly, the tilting guide portion (60) may not be disposed on the fourth side (71D) of the housing (210) to avoid spatial interference with the fourth substrate (804) of the circuit board (800). In the first to third guide portions (60A to 60C), the “guide portion” may be expressed as a “frame” or a “part.”

[0194] The tilting guide part (60) may be formed as an injection molded product. For example, the tilting guide part (60) may include a plastic, resin, or ceramic material. In another embodiment, the tilting guide part (60) may include a metal material, for example, a SUS material.

[0195] For example, the tilting guide part (60) may be an injection-molded product with a metal material inserted therein. For example, the tilting guide part (60) may include an inserted metal frame. This may increase the strength of the tilting guide part (60), prevent sagging of the tilting guide part (60), and prevent bending of the tilting guide part (60). In addition, the tilting guide part (60) may be a non-magnetic material. In another embodiment, the tilting guide part (60) may be a magnetic material.

[0196] The camera device (200) may include at least one first ball member arranged between the tilting guide part (60) and the holder (140). The camera device (200) may include at least one second ball member arranged between the tilting guide part (60) and the housing (210). The first ball member and the second ball member are expressed as separate components from the tilting guide part, but in other embodiments, the first ball member and the second ball member may be expressed as a component included in the tilting guide part. In this case, the “tilting guide part” may include a body (60) (or frame), the first ball member, and the second ball member.

[0197] For example, the first ball member may include two or more balls (65A1, 65B1), and the second ball member may include two or more balls (66A1, 66B1). For example, the first balls (65A1, 65B1) may be arranged spaced apart in the first axis direction, and the second balls (66A1, 66B1) may be arranged spaced apart in the second axis direction.

[0198] The first ball member may be placed between the protrusion (14) of the holder (140) and the upper surface of the tilting guide member (60). The second ball member may be placed between the lower surface of the tilting guide member (60) and the side portions (71A to 71C) of the housing (210).

[0199] The protrusion (14) of the holder (140) may include a groove (4) for arranging at least a portion of the first ball member (65A1, 65B1). Grooves (4A, 4B) may be formed in the protrusions (14A, 14B) of the holder (140). The two grooves (4A, 4B) may be arranged spaced apart from each other in the first axis direction.

[0200] The tilting guide part (60) may include a first groove (75) arranged or formed on the upper surface of the tilting guide part (60) and for placing at least a portion of the first ball member (65A1, 65B1). The first groove (75) may be recessed from the upper surface of the tilting guide part (60). For example, the first groove (75) may include two grooves (75A, 75B). For example, the grooves (75A, 75B) may be arranged to be spaced apart from each other in the first axis direction.

[0201] Additionally, the tilting guide part (60) may include a second groove (76) arranged or formed on the lower surface of the tilting guide part (60) and for placing at least a portion of the second ball member (66A1, 66B1). The second groove (76) of the tilting guide part (60) may be recessed from the lower surface of the tilting guide part (60). For example, the second groove (76) may include two grooves (76A1, 76B1). The grooves (76A, 76B) may be arranged to be spaced apart from each other in the second axis direction.

[0202] In another embodiment, the first balls may be arranged spaced apart in the second axis direction, the first grooves of the tilting guide portion (60) may be arranged spaced apart in the second axis direction, the second balls may be arranged spaced apart in the first axis direction, and the second grooves of the tilting guide portion (60) may be arranged spaced apart in the first axis direction.

[0203] In another embodiment, the first balls and the first grooves may be spaced apart in a first horizontal direction (or a second horizontal direction), and the second balls and the second grooves may be spaced apart in a second horizontal direction (or the first horizontal direction).

[0204] The housing (210) may include a groove (55) for arranging at least another portion of the second ball member. The housing (210) may include two grooves (55A, 55B) corresponding to two second balls (66A1, 66B1). The two grooves (55A, 55B) may be arranged to be spaced apart from each other in the second axial direction. The two second balls (66A1, 66B1) may be arranged on two corner portions of the housing (210) that are opposite to each other in the second axial direction. The two grooves (55A, 55B) may be arranged on two corner portions of the housing (210) that are opposite to each other in the second axial direction.

[0205] The tilting guide part (60) may include a first part (A1, A4, A7) and a second part (A2, A5, A8) positioned higher than the first part (A1, A4, A7) in the optical axis direction. In addition, the tilting guide part (60) may include a third part (A3, A6, A9) connecting the first part (A1, A4, A7) and the second part (A2, A5, A8).

[0206] The upper surface of the second part (A2, A5, A8) of the tilting guide part (60) may be positioned higher than the upper surface of the first part (A1, A4, A7) of the tilting guide part (60). The lower surface of the second part (A2, A5, A8) may be positioned higher than the lower surface of the first part (A1, A4, A7).

[0207] The lower surface of the second portion (A2, A5, A8) may be positioned lower than the upper surface of the first portion (A1, A4, A7).

[0218] The description of the lengths of the first to third areas (A1 to A3) of the first guide portion (60A) can be applied or analogically applied to the fourth to sixth areas (A4 to A6) of the second guide portion (60B) and the seventh to ninth areas (A7 to A9) of the third guide portion (60C).

[0219] Referring to FIG. 9A, the balls (65A1, 65B1) of the first ball member can be placed on the first portion (A1, A4, A7) of the tilting guide portion (60). The ball (65A1) can be placed on the portion (59A) where the first guide portion (60A) and the third guide portion (60C) meet or are connected. At least a portion of the ball (65A1) can be in contact with the connecting portion (59A). The ball (65B1) can be placed on one end (59B) of the second guide portion (60B). At least a portion of the ball (65B1) can be in contact with one end (59B) of the second guide portion (60B).

[0220] For example, the groove (75A) may be formed in the connecting portion (59A), and the groove (75B) may be formed in one end (59B) of the second guide portion (60B). In order to secure a space for arranging the ball members (65A1, 65B1), the width of each of the connecting portion (59A) and one end (59B) of the second guide portion (60B) may be larger than the width of the guide portions (60A, 60B, 60C). The connecting portion (59A) and one end (59B) of the second guide portion (60B) may be included in the first portion (A1, A4, A7) of the tilting guide portion (60). The connecting portion (59A) may overlap with at least a portion (e.g., the protrusion (14A)) of the holder (140) in the optical axis direction. One end (59B) of the second guide portion (60B) may overlap with at least another part (e.g., protrusion (14B)) of the holder (140) in the direction of the optical axis.

[0221] Referring to FIG. 9B, the balls (66A1, 66B1) of the second ball member can be positioned below the second portion (A2, A5, A8) of the tilting guide portion (60). The ball (66A1) can be positioned below one end (59C) of the first guide portion (60A). At least a portion of the ball (66A1) can be in contact with one end (59C) of the first guide portion (60A). The ball (66B1) can be positioned below a portion (59D) where the second guide portion (60B) and the third guide portion (60C) meet or are connected. At least a portion of the ball (66B1) can be in contact with the connecting portion (59D).

[0222] For example, a groove (76A1) may be formed at one end (59C) of the first guide portion (60A), and a groove (76B1) may be formed at the connecting portion (59D). In order to secure space for arranging the ball members (66A1, 66B1), the width of each of the connecting portion (59D) and one end (59C) of the first guide portion (60A) may be larger than the width of the guide portions (60A, 60B, 60C).

[0223] One end (59C) and a connecting portion (59D) of the first guide portion (60A) may be included in the second portion (A2, A5, A8) of the tilting guide portion (60). One end (59C) of the first guide portion (60A) may overlap with at least another portion (e.g., a groove (55A)) of the housing (210) in the optical axis direction. The connecting portion (59D) may overlap with at least a portion (e.g., a groove (55B)) of the housing (210) in the optical axis direction.

[0224] The height difference (H1) in the optical axis direction between the center of the first ball member (65A1, 65B1) and the center of the second ball member (66A1, 66B1) is reduced by the third part (A3, A6, A9) of the tilting guide part (60), and thus the difference in the moment received by the first ball member (66A1, 66B1) and the second ball member (66A1, 66B1) can be reduced.

[0225] Since the difference in the moment received by the first ball member (65A1, 65B1) and the second ball member (66A1, 66B1) is reduced, in the embodiment, tilting control of the OIS moving part can be easily and simply performed around the first axis of the first ball members (65A1, 65B1) or the second axis of the second ball members (66A1, 66B1).

[0226] H1 may be less than or equal to the thickness (T1) of the tilting guide part (60) or the height of the tilting guide part (60) in the optical axis direction. The thickness (T1) may be the length of the tilting guide part (60) in the optical axis direction.

[0227] For example, the length (T1) of the first part (A1, A4, A7) of the tilting guide part (60) in the optical axis direction may be smaller than or equal to the diameter of the ball members (65A1 and 65B1, or 66A1 and 66B1). The length (T1) of the second part (A2, A5, A8) of the tilting guide part (60) in the optical axis direction may be smaller than or equal to the diameter of the ball members (65A1 and 65B1, or 66A1 and 66B1). This makes it possible to lower the height of the camera device (200) in the optical axis direction. The maximum length (T2) of the tilting guide part (60) in the optical axis direction may be smaller than the length of the holder (140) in the optical axis direction. For example, the maximum length (T2) of the tilting guide portion (60) in the optical axis direction may be smaller than the length (T3, see FIG. 4f) of the side portions (41A to 41D) of the holder (140) in the optical axis direction.

[0228] The length of the third part (A3, A6, A9) of the tilting guide part (60) in the optical axis direction may be greater than T1. This can prevent deformation or bending of the tilting guide part (60) due to impact, etc.

[0229] Referring to FIG. 12, the first ball members (65A1, 65B1) may be arranged to correspond to, oppose, or overlap two corner parts (CA1, CA2) located on opposite sides of the housing (210), and the second ball members (66A1, 66B1) may be arranged to correspond to, oppose, or overlap two other corner parts (CA3, CA4) located on opposite sides of the housing (210). In another embodiment, the first ball members may be arranged to correspond to, oppose, or overlap two side parts (71A, 71B) of the housing (210), and the second ball members may be arranged to correspond to, oppose, or overlap two other side parts (71C, 71D) of the housing (210).

[0230] Referring to FIGS. 9d and 9e, a tilting guide part (60-1) according to another embodiment may include protrusions (65A, 65B) connected to or in contact with the holder (140) and protrusions (66A, 66B) connected to or in contact with the housing (210). The protrusions (65A, 65B) of FIG. 9d may have a configuration corresponding to the ball members (65A1, 65B1) of FIG. 9a, and the protrusions (66A, 66B) of FIG. 9e may have a configuration corresponding to the ball members (66A1, 66B1) of FIG. 9b.

[0231] The protrusions (65A, 65B) may be arranged on the upper surface of the tilting guide part (60-1), and the protrusions (66A, 66B) may be arranged on the lower surface of the tilting guide part (60). For example, the protrusions (65A, 65B) may protrude from the upper surface of the tilting guide part (60), and the protrusions (66A, 66B) may protrude from the lower surface of the tilting guide part (60). The number of protrusions (65A, 65B) is two, but in other embodiments, it may be one or three or more. In addition, the number of protrusions (66A, 66B) is two, but in other embodiments, it may be one or three or more.

[0232] At least a portion of the protrusions (65A, 65B) may be arranged within the grooves (4A, 4B) of the protrusions (14A, 14B) of the holder (140). For example, the two protrusions (65A, 65B) may be arranged spaced apart from each other in the first axial direction. Each of the two protrusions (65A, 65B) may be inserted into and arranged in a corresponding one of the grooves (4A, 4B) of the protrusions (14A, 14B) of the holder (140). In another embodiment, the two protrusions (65A, 65B) may be arranged spaced apart from each other in the first horizontal direction or the X-axis direction.

[0233] Additionally, at least a portion of the protrusions (66A, 66B) may be positioned within the grooves (55) of the housing (140). For example, the two protrusions (66A, 66B) may be positioned spaced apart in the second axial direction. Each of the two protrusions (66A, 66B) may be positioned by being inserted into a corresponding one of the grooves (55A, 55B) of the housing (210). In another embodiment, the two protrusions (66A, 66B) may be positioned spaced apart in the second horizontal direction or the Y-axis direction.

[0235] For example, each of the protrusions (65A, 65B) and the protrusions (66A, 66B) may have a curved shape, a hemispherical shape, a dome shape, or a polyhedral shape, but is not limited thereto. For example, the shape of the first protrusion (65) when viewed from above and the shape of the second protrusion (66) when viewed from below may be circular, oval, or polygonal. The protrusions (65A, 65B) and the protrusions (66A, 66B) may be arranged in parallel along directions intersecting or perpendicular to each other. The OIS moving part may be rotated, axially rotated, or tilted by a preset angle based on the first axis by the protrusions (65A, 65B) of the tilting guide part (60). And the OIS moving part can be rotated, axially rotated, or tilted based on the second axis by the protrusions (66A, 66B) of the tilting guide part (60). In another embodiment, the tilting guide part (60) may omit at least one of the protrusions (65A, 65B) and the protrusions (66A, 66B), and a cloud member or a ball member may be arranged instead of the omitted protrusion.

[0236] A lubricant may be placed in at least one of the grooves (75, 76) of the tilting guide part (60), the groove (4) of the holder (140), and the groove (55) of the housing (210) to reduce friction and protect the tilting guide part (60).

[0237] The support member may include a magnetic body (33) disposed on an OIS moving member (e.g., a sensor base (270)) and a magnetic body (31) disposed on a fixed member (e.g., a housing (210)). The magnetic bodies (31, 32) may be alternatively expressed as a “magnet,” a “yoke,” or a “holding magnet.” The support member may further include a support member (64).

[0238] The magnetic body (31) may be placed or coupled to the lower portion (42) of the housing (210).

The magnetic body (31) may not overlap with the tilting guide portion (60) in the direction of the optical axis. In addition, at least a portion of the magnetic body (31) may not overlap with the tilting guide portion (60) in the direction perpendicular to the optical axis. The magnetic body (31) does not overlap with the tilting guide portion (60) in the direction parallel to the first axis or the direction parallel to the second axis. The magnetic body (31) may correspond to, face, or overlap with the magnetic body (33) in the direction of the optical axis.

[0239] The magnetic body (31) may be a two-pole magnet divided or arranged into N and S poles. For example, the magnetic body (31) may be a two-pole magnet divided or arranged into N and S poles in the direction of the optical axis. In another embodiment, the magnetic body (31) may be a two-pole magnet divided or arranged into N and S poles in a direction perpendicular to the optical axis. In yet another embodiment, the magnetic body (31) may be a four-pole magnet including two N poles and two S poles.

For example, the support member (64) can be coupled with the extension (217) of the sensor base (270) or assembled to the extension (217). For example, the support member (64) can be coupled with the extension (217) of the base (270) by an adhesive.

[0241] The support member (64) may be alternatively expressed as a “magnetic support member”, “sensor base rigid”, “support”, “mover rigid”, “holding rigid”, “joint”, or “plate”. For example, the support member (64) may be formed of an injection-molded material, plastic, or resin material, or, for example, the support member (64) may be formed of a metal material or a metal plate. Alternatively, the support member (64) may be formed of a heat dissipation material. The support member (64) may have a polyhedral (e.g., hexahedral) shape. The support member (64) may have a plate shape. For example, when viewed from above or in the direction of the optical axis, the support member (64) may have a polygonal, e.g., square, shape. For example, when viewed from above or in the direction of the optical axis, the support member (64) may have a rectangular, square, circular, or oval shape.

[0242] FIG. 14a is a cut perspective view of the camera device (200) in the first axis direction, FIG. 14b is a cut perspective view of the camera device (200) in the second axis direction, and FIG. 14c shows a part of the cut perspective view of the camera device (200).

The fixed member may include an opening (18) in which the first portion of the moving module is disposed.

[0245] In the embodiment of FIG. 7d, the extension (217) corresponds to a part of the sensor base (270) and may be formed integrally with the sensor base (270). A camera device according to another embodiment may have a separate coupling member from the sensor base (270) instead of the extension (217). In this case, the separate coupling member may be coupled to the sensor base (270). For example, the coupling member may be coupled to the sensor base (270) by an adhesive. For example, the coupling member may include a first coupling structure (e.g., a protrusion or a groove), and the sensor base (270) may include a second coupling structure (e.g., a groove or a protrusion) for coupling with the first coupling structure. For example, one end of the coupling member may be coupled to the lower portion (or bottom surface) of the sensor base (270), and the other end of the coupling member may be coupled to the support member (64).

[0246] The magnetic body (33) may be placed on the lower side of the magnetic body (31). The magnetic body (31) may be positioned higher than the magnetic body (33). The magnetic body (33) may be placed on or coupled to the support member (64). Referring to FIG. 7A, the support member (64) may include a mounting portion (93A) (or receiving portion). The mounting portion (93A) may be a groove. For example, the mounting portion (93A) may be a groove that is recessed from the upper surface of the support member (64). For example, the magnetic body (33) may be coupled to the mounting portion (93A) of the support member (64). For example, the magnetic body (33) may be coupled, attached, or fixed to the mounting portion (93A) of the support member (64) by an adhesive.

[0247] The magnetic body (33) may not overlap with the tilting guide part (60) in the direction of the optical axis.

The tilting guide part (60) may be positioned higher than the image sensor (810). The tilting guide part (60) may be positioned higher than the first substrate (801) of the circuit board (800).

[0248] A repulsive force may be applied between the magnetic body (33) and the magnetic body (31) in the direction of the optical axis (or the first direction). The magnetic body (33) and the magnetic body (31) may be arranged so that the repulsive force is applied to each other. The magnetic body (33) may be made of a magnetic material. For example, the magnetic body (33) may include a magnetic metal material. Or, for example, the magnetic body (33) may be made of a magnetic metal material. Or, for example, the magnetic body (33) may be a magnet. The magnetic bodies (31, 32) may be expressed as a "yoke". Each of the magnetic bodies (33, 31) may also be expressed as a "repulsive magnet". For example, the magnetic bodies (33) and the magnetic body (31) may be arranged so that their surfaces facing or opposing each other in the optical axis direction have the same polarity. For example, the N pole (or S pole) of the magnetic body (33) and the N pole (or S pole) of the magnetic body (31) may face or oppose each other in the optical axis direction. The first surface of the magnetic body (33) may face the first surface of the magnetic body (31), and the first surface of the magnetic body (33) and the first surface of the magnetic body (31) may have the same polarity. For example, the second surface of the magnetic body (33) may be the opposite surface of the first surface of the magnetic body (33), the second surface of the magnetic body (31) may be the opposite surface of the first surface of the magnetic body (31), and the second surface of the magnetic body (33) and the second surface of the magnetic body (31) may have the same polarity.

[0249] The coupling portion (49) of the housing (210) may be positioned between the sensor base (210) and the support member (64). The coupling portion (49) and the magnetic body (31) may be positioned between the sensor base (270) and the magnetic body (33). The image sensor (810) or the filter (610) may be positioned closer to the magnetic body (31) than to the magnetic body (33). That is, among the magnetic bodies (31) and the magnetic bodies (33), the magnetic body (31) may be positioned closer to the image sensor (810). For example, the lower surface of the lower portion (42) of the housing (210) may be positioned closer to the magnetic body (33) than to the magnetic body (31). For example, the support member (64) and the magnetic body (33) may be positioned below the tilting guide portion (60).

[0250] The tilting guide part (60) can be brought into close contact with the OIS moving part and the fixed part by the repulsive force acting between the magnetic body (33) and the magnetic body (31). The tilting guide part (60) can be pressed against the moving part by the repulsive force of the magnetic body (33) and the magnetic body (31). The lower surface of the protrusion (14) of the holder (140) can press the tilting guide part (60) and the first ball member (65A1, 65B1) by the repulsive force acting between the magnetic body (33) and the magnetic body (31). In addition, the side portions (71A to 71C) of the housing (210) can press the tilting guide part (60) and the second ball member (66A1, 66B1) by the repulsive force acting between the magnetic body (33) and the magnetic body (31). Due to this, the tilting guide part (60) can be brought into close contact with the sensor base (270) and / or the housing (210). Due to the repulsive force between the magnetic body (33) and the magnetic body (31), the tilting guide part (60) can stably support the OIS moving part (100) with respect to the fixed part, and stable OIS operation can be performed.

[0251] In addition, since the magnetic body (31) is disposed in a joint portion (49) corresponding to or opposite the central region of the lower portion (42) of the housing (210), and the magnetic body (33) is disposed in an area of ​​the support member (64) corresponding to or opposite the central region of the lower surface of the sensor base (270), the repulsive force between the magnetic bodies (31) and (33) can be concentrated in the central region of the OIS moving part, thereby allowing the OIS moving part to be supported in a balanced and stable manner. In another embodiment, the joint portion (49) may be omitted, and the magnetic body (31) may be disposed on the upper surface of the lower portion (42) of the housing (210).

[0252] In FIGS. 1 to 18c, the tilting guide part (60) is brought into close contact with the OIS moving part (e.g., holder (140)) and the fixed part (e.g., housing (210)) by the repulsive force acting between the magnetic body (31) and the magnetic body (33), but in another embodiment, the tilting guide part (60) may be pressed by the attractive force between the first magnetic body arranged on the OIS moving part (e.g., sensor base (270)) and the second magnetic body arranged on the fixed part (e.g., housing (210)), and the OIS moving part may be brought into close contact with the fixed part. In this case, the extension part (217) of the sensor base (270) may be omitted, the first magnetic body may be arranged on the lower surface of the sensor base (270), and the image sensor (810) may be positioned closer to the first magnetic body than to the second magnetic body. That is, the first magnetic body can be located between the image sensor (810) and the second magnetic body.

[0253] Referring to FIGS. 12 and 16A, when viewed from above, the first magnet unit (310A) may overlap with the protrusions (65A, 65B) of the first ball members (65A1, 65B1) or the tilting guide member (60-1) in the first axis direction. Also, when viewed from above, the first magnet unit (310B) may overlap with the protrusions (66A, 66B) of the second ball members (66A1, 66B1) or the tilting guide member (60-1) in the second axis direction.

[0254] For example, the magnet (310) and the yoke (380) may be positioned below the image sensor (810). For example, the magnet (310) may be positioned below the filter (610). Additionally, the magnet (310) may be positioned below the magnetic body (33). For example, the magnet (310) may be positioned below the holder (140). For example, the magnet (310) may be positioned below the sensor base (270). For example, the upper surface of the magnet (310) may be positioned below the lower surface of the sensor base (270). The upper surface of the magnet (310) may be positioned below the lower surface of the holder (140). The upper surface of the magnet (310) may be positioned below the lower surface of the magnetic body (33). For example, the magnet (310) may be positioned below the cloud member (21).

[0255] Referring to FIG. 4F, for example, the upper surface of the magnet unit (310A, 310B) may be positioned lower than the upper surface of the magnetic body (31). In another embodiment, the upper surface of the magnet unit (310A, 310B) may be positioned higher than the upper surface of the magnetic body (31) or may be the same height as the upper surface of the magnetic body (31). For example, the upper surface of the magnet unit (310A, 310B) may be positioned lower than the lower surface of the magnetic body (31). In another embodiment, the upper surface of the magnet unit (310A, 310B) may be positioned higher than the lower surface of the magnetic body (31) or may be the same height as the lower surface of the magnetic body (31). For example, the support member (64) and the magnetic body (33) may be positioned lower than the coupling portion (49) of the housing (210).

[0256] For example, the upper surface of the magnet unit (310A, 310B) may be positioned lower than the upper surface of the coupling portion (49) of the housing (210). This is to secure sufficient space to avoid spatial interference between the magnet (310) and the lower surface of the sensor base (270). In another embodiment, the upper surface of the magnet unit (310A, 310B) may be positioned higher than the upper surface of the coupling portion (49) of the housing (210). In yet another embodiment, the upper surface of the magnet unit (310A, 310B) and the upper surface of the coupling portion (49) of the housing (210) may have the same height.

[0257] Referring to FIGS. 1, 4F, 9A, 9B, and 14B, the upper plate (301) of the cover member (300) may include a recessed portion (306) that is recessed toward the tilting guide portion (60). The recessed portion (306) may be spaced apart from the tilting guide portion (60) by a preset distance. The recessed portion (306) may correspond to, face, or overlap the second ball member (66A1, 66B1) in the optical axis direction. The recessed portion (306) may overlap the second part (A2, A5, A8) of the tilting guide portion (60) where the second ball member (66A1, 66B1) is arranged in the optical axis direction.

[0258] For example, the recessed portion (306) may include a first recessed portion (306A) corresponding to, opposite to, or overlapping with one end (59C) of the first guide portion (60A) in the optical axis direction, and a second recessed portion (306A) corresponding to, opposite to, or overlapping with the connecting portion (59D) in the optical axis direction. The distance (d1, see FIG. 4f) between the recessed portion (306) and the tilting guide portion (60) is smaller than the distance between the tilting guide portion (60) and the upper plate (301). The recessed portion (306) may be expressed as a “stepped portion” having a step in the optical axis direction with respect to the upper plate (301). Alternatively, the recessed portion (306) may be expressed instead as a “groove”.

[0259] The recessed portion (306) can limit the movement of the tilting guide portion (60) in the optical axis direction. By limiting the movement of the tilting guide portion (60) in the optical axis direction, the recessed portion (306) can prevent the tilting guide portion from being detached or dropped from the housing (210) due to impact, etc. In addition, the recessed portion (306) can prevent the second ball members (66A1, 66B1) from being detached from the groove (76) of the tilting guide portion (60) or the groove (55) of the housing (210). For example, the distance (d1) between the recessed portion (306) and the tilting guide portion (60) can be smaller than or equal to the diameter of the second ball members (66A1, 66B1). In another embodiment, d1 may be larger than the diameter of the second ball member (66A1, 66B1) and smaller than twice the diameter of the second ball member (66A1, 66B1).

[0260] Fig. 15 is a perspective view of a camera device (200) including a shield member (390).

[0261] Referring to FIG. 15, the camera device (200) may include a shield member (390) that closes the opening (18) of the housing (210). The shield member (390) may be coupled or attached to the lower surface of the lower portion (42) of the housing (210). The shield member (390) may be coupled to the housing (210) by an adhesive. For example, the shield member (390) may be in the form of an adhesive tape. The shield member (390) may also be expressed as a “cover,” a sealing member, or a “shield tape.”

[0262] Fig. 16a shows the electromagnetic force (F1, F2) according to the interaction between the magnet units (310A, 310B) and the coil units (230A, 230B), and Fig. 16b shows the movement of the OIS moving part (100) due to the electromagnetic force of Fig. 16a. Fig. 16a shows the electromagnetic force when the first and second magnet units (310A, 310B) are two-pole magnets having an N pole and a S pole.

[0263] Referring to FIGS. 16A and 16B, the movement operation of the OIS moving unit by the OIS driving unit will be described. The OIS driving unit may include a coil (230) and a magnet (310). In addition, the OIS driving unit may include a position sensor (240). The AF driving unit may be expressed as one of the "first driving unit" and the "second driving unit," and the OIS driving unit may be expressed as the other of the "first driving unit" and the "second driving unit."

[0264] For example, a first surface (e.g., an upper surface) of a first magnet unit (310A) facing or opposing the first coil unit (230A) in the optical axis direction and a first surface (e.g., an upper surface) of a second magnet unit (310B) facing or opposing the second coil unit (230B) in the optical axis direction may have opposite polarities. By making the first surface (e.g., an upper surface) of the first magnet unit (310A) and the first surface (e.g., an upper surface) of the second magnet unit (310B) have opposite polarities, the influence of the magnetic field of the first magnet unit (310A) on the second coil unit (230B) and the influence of the magnetic field of the second magnet unit on the first coil unit (230A) may cancel each other out, and magnetic field balancing may be implemented. As a result, the influence of unnecessary magnetic fields caused by two adjacent magnet units (310A, 310B) on the coil units (230A, 230B) can be suppressed or reduced, and the camera device (200) can improve the performance and reliability of OIS operation.

[0265] In addition, by making the first surface (e.g., the upper surface) of the first magnet unit (310A) and the first surface (e.g., the upper surface) of the second magnet unit (310B) have opposite polarities, the influence of the magnetic field of the first magnet unit (310A) on the second sensor (240B) and the influence of the magnetic field of the second magnet unit on the first sensor (240A) can be canceled out, and magnetic field balancing can be implemented. As a result, the influence of unnecessary magnetic fields originating from adjacent magnet units (310A, 310B) on the sensors (240A, 240B) can be suppressed or reduced, the reliability of the output of the sensors (240A, 240B) can be improved, and the performance and reliability of OIS operation can be improved.

[0266] Also, for example, the second surface (e.g., the lower surface) of the first magnet unit (310A) and the second surface (e.g., the lower surface) of the second magnet unit (310B) may have opposite polarities. The second surface (e.g., the lower surface) of the first magnet unit (310A) may be the opposite surface of the first surface (e.g., the upper surface) of the first magnet unit (310A) and may have a polarity that is opposite to the polarity of the first surface (e.g., the upper surface) of the first magnet unit (310A). The second surface (e.g., the lower surface) of the second magnet unit (310B) may be the opposite surface of the first surface (e.g., the upper surface) of the second magnet unit (310B) and may have a polarity that is opposite to the first surface (e.g., the upper surface) of the second magnet unit (310B). For example, the first surface of the first magnet unit (310A) may be an N pole (or S pole), and the first surface of the second magnet unit (310B) may be an S pole (or N pole).

[0267] A first electromagnetic force (F1) may be generated by the interaction between the first magnet unit (310A) and the first coil unit (230A). For example, the first electromagnetic force (F1) may be applied in the direction of the optical axis, for example, in the upward or downward direction. The OIS moving unit (100) may be tilted about the second axis (or the second ball member (66A1, 66B1)) by the first electromagnetic force (F1). For example, the OIS moving unit (100) may be tilted about the second axis by the first electromagnetic force (F1). Here, the second-axis tilting may mean that the OIS moving unit is tilted based on the second axis or that the OIS moving unit is rotated by a preset angle about the second axis as the rotation axis.

[0268] A second electromagnetic force (F2) may be generated by the interaction between the second magnet unit (310B) and the second coil unit (230B). For example, the second electromagnetic force (F2) may be applied in an upward or downward direction. The OIS moving unit may be tilted about the first axis (or the first ball members (65A1, 65B1)) by the second electromagnetic force (F2). For example, the OIS moving unit may be tilted about the first axis by the second electromagnetic force (F2). Here, the first-axis tilting may mean that the OIS moving unit is tilted based on the first axis or that the OIS moving unit is rotated by a preset angle about the first axis as the rotation axis.

[0269] Fig. 16c shows the arrangement of magnet units (310A, 310B) according to a modified example of Fig. 16a. Referring to Fig. 16c, a first surface (e.g., an upper surface) of a first magnet unit (310A) facing or opposite a first coil unit (230A) in the optical axis direction and a first surface (e.g., an upper surface) of a second magnet unit (310B) facing or opposite a second coil unit (230B) in the optical axis direction may have the same polarity. For example, the first surface of the first magnet unit (310A) and the first surface of the second magnet unit (310B) may be N poles (or S poles), and the second surface of the first magnet unit (310A) and the second surface of the second magnet unit (310B) may be S poles (or N poles).

[0270] FIG. 16d shows electromagnetic forces (F11, F12) according to the interaction between magnet units (310A1, 310B1) and coil units (230A, 230B) according to another embodiment.

[0271] Referring to FIG. 16d, the first magnet unit (310A1) may be a magnet that is divided or arranged into one N pole and one S pole in the first axis direction. The second magnet unit (310B1) may be a magnet that is divided or arranged into one N pole and one S pole in the second axis direction. For example, the first surface of the first magnet unit (310A1) may include an N pole and a S pole, and the first surface of the second magnet unit (310B1) may include an N pole and a S pole.

[0272] The first electromagnetic force (F11) resulting from the interaction between the first magnet unit (310A1) and the first coil unit (230A) may act in a direction different from the optical axis (e.g., in the first axis direction). The second electromagnetic force (F12) resulting from the interaction between the second magnet unit (310B1) and the second coil unit (230) may act in a direction different from the optical axis (e.g., in the second axis direction). For example, the first electromagnetic force (F11) resulting from the interaction between the first magnet unit (310A1) and the first coil unit (230A) may act in a direction perpendicular to the optical axis. In addition, the second electromagnetic force (F12) resulting from the interaction between the second magnet unit (310B1) and the second coil unit (230B) may act in a direction perpendicular to the optical axis. For example, F11 and F12 can act in intersecting directions (e.g., perpendicular directions).

[0273] In FIG. 16d, the first pole of the first magnet unit (310A1) may be positioned closer to the tilting guide portion (60) than the second pole of the first magnet unit (310A1). In addition, the second pole of the second magnet unit (310B1) may be positioned closer to the tilting guide portion (60) than the first pole of the second magnet unit (310B1). Alternatively, the first pole of the first magnet unit (310A1) may be positioned on the inside, and the second pole of the first magnet unit (310A1) may be positioned on the outside.

[0274] On the other hand, the first pole of the second magnet unit (310B1) may be located on the outside, and the second pole of the second magnet unit (310B1) may be located on the inside. For example, the first pole may be a N pole (or S pole), and the second pole may be a S pole (or N pole). In another embodiment, the first magnet unit (310A1) and the second magnet unit (310B1) may be arranged so that their opposite polarities are closer to the tilting guide portion (60). The description of the magnetic field balancing of the embodiment of FIG. 16A may be applied or analogized to the embodiment of FIG. 16D.

[0275] In another embodiment, the first magnet unit (310A1) and the second magnet unit (310B1) may be arranged so that the same polarity (e.g., N pole or S pole) is close to the optical axis.

[0276] The OIS moving unit can be tilted about the second axis (or the second ball members (66A1, 66B1)) by the first electromagnetic force (F11). For example, the OIS moving unit can be tilted about the second axis by the first electromagnetic force (F11). The OIS moving unit can be tilted about the first axis (or the first ball members (65A1, 65B1)) by the second electromagnetic force (F12). For example, the OIS moving unit can be tilted about the first axis by the second electromagnetic force (F12). The yoke (380) can serve to increase the electromagnetic forces (F1, F2, F11, F12) (or driving force) of FIGS. 16A, 16C, and 16D.

[0277] In FIGS. 16A to 16D, the OIS moving part can be tilted about a first axis or a second axis in a diagonal direction by the magnet units (310A, 310B), the coil units (230A, 230B), the tilting guide part (60), the first ball member (65A1, 65B1), and the second ball member (66A1, 66B1). In other embodiments, the arrangement of the magnet units (310A, 310B) and the coil units (230A, 230B), and the arrangement of the axes according to the first and second ball members may be changed to enable X-axis tilting or Y-axis tilting.

[0278] In a camera device (hereinafter referred to as "Comparative Example 1") in which the image sensor is fixed and the lens is moved in a direction perpendicular to the optical axis for image stabilization or shake correction, image distortion may occur. In addition, in a camera device (hereinafter referred to as "Comparative Example 2") in which the lens is fixed but the image sensor is moved or tilted for image stabilization or shake correction, image distortion may occur at the edge or corner of the image sensor. In Comparative Examples 1 and 2, since the image sensor and the lens are separated and only one of the image sensor and the lens is moved or tilted, image distortion may occur during image stabilization, and it may be difficult to correct for high-angle shake.

[0279] In an embodiment, for image stabilization, the OIS driving unit can tilt the OIS moving unit (100) based on the first axis or the second axis or rotate it within a preset angle range. In an embodiment, since the OIS moving unit (100) includes a lens module (400) and an image sensor (810), when the OIS is driven, the tilting direction (or rotation direction) and the tilting angle (or rotation angle) of the lens module (400, e.g., a lens or lens module) (or bobbin (110)) may be the same as or nearly the same as the tilting direction (or rotation direction) and the tilting angle (or rotation angle) of the image sensor (810).

[0280] In the embodiment, when OIS is driven, the lens module (400) (or bobbin (110)) and the image sensor (810) tilt or rotate together, so that there is no image distortion and 100% image resolution can be obtained, and high-angle shake correction or shake correction can be possible.

[0281] In addition, since the OIS moving part including the lens module (400) (or bobbin (110)) and the image sensor (810) tilts or rotates in the embodiment, even if shake occurs in the camera device, image degradation does not occur in the center of the image sensor and the outer part of the image sensor (e.g., the corner or corner area of ​​the image sensor). Therefore, the embodiment can perform shake correction in a high-broadband. In addition, since the embodiment can perform image correction without mechanical distortion, the load received during image processing is less compared to Comparative Examples 1 and 2, so that current consumption can be reduced.

[0282] In addition, since in the embodiment, a tilting guide part (60) is used for tilting the OIS moving part, compared to an example that uses only a ball member or a shaft member, the OIS moving part can be tilted stably, precisely, and accurately, thereby improving the reliability of OIS operation.

[0283] In addition, in the embodiment, the tilting guide part (60) is not arranged to overlap with the image sensor (810) or the sensor base (270) in the optical axis direction, but is arranged on the outside of the side of the sensor base (270), thereby lowering the height of the camera device (200) in the optical axis direction.

[0284] In addition, in the embodiment, since the tilting guide part (60) is formed as an injection molded product with a metal frame inserted, the rigidity of the tilting guide part (60) can be increased, and thus deformation or bending of the tilting guide part (60) can be prevented when the OIS moving part for OIS operation is tilted.

[0285] In addition, in the embodiment, the tilting guide part (60) includes a first part (A1, A4, A7) and a second part (A2, A5, A6) having a step in the optical axis direction, and a first ball member (65A1, 65B1) may be arranged in the first part (A1, A4, A7), and a second ball member (66A1, 66B1) may be arranged in the second part (A2, A5, A6), and the difference in height in the optical axis direction between the first ball member (65A1, 65B1) and the second ball member (66A1, 66B1) may be reduced. Due to this, the difference between the moment (or force) received by the first ball member (65A1, 65B1) and the moment (or force) received by the second ball member (66A1, 66B1) when tilting the OIS moving part for OIS operation can be reduced, and control for the first-axis tilting and the second-axis tilting can be made easy and simple.

[0286] In addition, in the embodiment, the power consumption required for driving the OIS can be reduced by the bending portions (804D, 804E) and the third portion (804C) of the fourth substrate (804), which is a flexible substrate of the circuit board (800).

[0287] In addition, in the embodiment, the tilting guide part (60) is positioned on the side (71A to 71C) of the housing (210), and the tilting guide part (60) is positioned on the outside of the side (41A to 41C) of the holder (140), so that the height or length in the optical axis direction of the camera device (200) can be reduced.

[0288] In addition, in the embodiment, since at least a part of the magnetic body (33) is positioned within the opening (18) of the housing (210), the separation distance between the magnetic body (31) and the magnetic body (33) can be reduced, and thus the repulsive force or holding force for supporting the OIS moving part can be increased, thereby enabling stable OIS operation.

[0289] In addition, in the embodiment, since the first magnet unit (310A) and the second magnet unit (310B), which are driving magnets for image stabilization, are arranged on the lower part (42) of the housing (210) rather than on the side parts (71A to 71D) of the housing (210), the thickness (or length in the direction perpendicular to the optical axis) of the side parts (71A to 71D) of the housing (210) can be reduced, and thus, the camera device can be designed so as to be able to mount a large-diameter lens.

[0290] Fig. 17 is a perspective view of a camera device (200) including a lens module (400).

[0291] Referring to FIG. 17, the lens module (400) can be coupled to the bobbin (100) and can move together with the bobbin (110) in the optical axis direction. For example, the lens module (400) can include at least one of a lens and a lens barrel. In an embodiment, when performing shake correction or shake correction, the lens module (400) and the image sensor (810) can simultaneously tilt in the same direction and at the same angle along the first axis or the second axis.

[0292] Fig. 18a shows the first position of the OIS moving part (100), and Fig. 18b shows the second position of the OIS moving part (100).

[0293] Referring to FIGS. 16A, 18A, and 18B, the OIS moving unit (100) can be tilted about the first axis by a preset angle (θ1) based on the first axis (or the first ball members (65A1, 65B1)) by a force (F2) resulting from the interaction between the second magnet unit (310B) and the second coil unit (230B). That is, when the OIS moving unit (100) moves from the first position to the second position, both the image sensor (810) and the lens module (400) can be tilted simultaneously by the preset angle (θ1). In addition, when the OIS moving unit (100) moves from the first position to the second position, the tilting guide unit (60) can be tilted by the preset angle (θ1) together with the image sensor (810) and the lens module (400).

[0294] Figure 18c shows the third position of the OIS moving part (100).

[0295] Referring to FIG. 18c, the OIS moving unit (100) can be tilted along the second axis by a preset angle (θ2) based on the second axis (or the second ball members (66A1, 66B1)) by a force (F1) resulting from the interaction between the first magnet unit (310A) and the first coil unit (230A). For example, when the OIS moving unit (100) moves from the first position to the third position, both the image sensor (810) and the lens module (400) can be tilted simultaneously by the preset angle (θ2).

[0296] Since the image sensor (810) and the lens module (400) are simultaneously tilted together with respect to the first axis or the second axis by force (F1) or force (F2), the embodiment can obtain 100% image resolution without image distortion, and high-angle shake correction or shake correction can be possible.

[0297] For example, when viewed from above or in the direction of the optical axis, the first axis may be a first diagonal direction of the OIS moving unit (100), and the second axis may be a second diagonal direction of the OIS moving unit (100). For example, the first diagonal direction of the OIS moving unit may be a first diagonal direction of any one of the holder (140), the sensor base (270), or the first substrate (801) of the circuit board (900). In addition, the second diagonal direction of the OIS moving unit may be a second diagonal direction of any one of the holder (140), the sensor base (270), or the first substrate (801) of the circuit board (900).

[0298] In another embodiment, when viewed from above or in the direction of the optical axis, the first axis may be a first diagonal direction of the fixing portion, and the second axis may be a second diagonal direction of the fixing portion. For example, the first diagonal direction of the fixing portion may be a first diagonal direction of the housing (210) or the cover member (300). Additionally, the second diagonal direction of the fixing portion may be a second diagonal direction of the housing (210) or the cover member (300).

[0299] For example, the first diagonal direction of the OIS moving unit (100) (or the fixed unit) may be a direction intersecting with the second direction (e.g., the X-axis direction) or the third direction, and the second diagonal direction of the OIS moving unit (100) (or the fixed unit) may be a direction intersecting with the second direction (e.g., the X-axis direction) or the third direction. The first diagonal direction of the OIS moving unit (100) and the second diagonal direction of the OIS moving unit (100) may intersect each other. For example, the first diagonal direction of the OIS moving unit (100) and the second diagonal direction of the OIS moving unit (100) may be perpendicular to each other.
