[0032] In this embodiment, the OIS operating unit includes a lens module and an image sensor, so that when the OIS is driven, the lens module and the image sensor can tilt or rotate simultaneously, resulting in no image distortion, 100% image resolution, and wide-angle image stabilization or shake correction.

[0033] In addition, in the embodiment, the OIS operating unit including the lens module and the image sensor tilts or rotates, so that wideband shake correction is possible.

[0034] Furthermore, in the embodiment, since image correction without mechanical distortion is possible, the load on the image processing is small, and current consumption can be reduced.

[0035] In addition, in the embodiment, a moving plate is used to tilt the OIS operating part, so compared to examples that simply use a ball member or a shaft member, the OIS operating part can be tilted stably, precisely, and accurately, thereby improving the reliability of the OIS drive.

[0036] In addition, in this embodiment, the bent portion and the third portion of the fourth substrate, which is a flexible substrate of the circuit board, can reduce the power consumption required to drive the OIS.

[0037] In addition, in the embodiment, the moving plate is disposed within the seat of the sensor base, and the protruding portion of the sensor base overlaps with the opening of the moving plate, thereby reducing the height or length of the camera device in the optical axis direction.

[0038] In addition, in the embodiment, at least a portion of the magnetic material is positioned within the opening of the moving plate, so that the attractive force or holding force for supporting the OIS operating part can be increased, enabling stable OIS driving to be performed.

[0039] In addition, in the embodiment, the driving magnet for image stabilization is arranged at the bottom of the housing rather than at the side of the housing, so the thickness of the side of the housing can be reduced, and therefore the camera device can be designed to be able to mount a large-diameter lens.

[0040] In addition, in the embodiment, the driving magnet for image stabilization is placed at the bottom of the housing, so it is not limited by the length of the driving magnet in the optical axis direction, and can be designed to reduce the length of the camera device in the optical axis direction.

Also, when "on or under" is used, it can mean not only above but also below an element.

[0097] Additionally, relational terms such as "first" and "second," "top / upper / upper" and "bottom / lower / lower" used hereinafter do not necessarily require or imply any physical or logical relationship or sequence between such entities or elements, but may be used only to distinguish one entity or element from another. Additionally, the same reference numerals refer to the same elements throughout the description of the figures.

[0098] Furthermore, unless otherwise specified, the terms "comprise," "constitute," or "have" used below mean that the corresponding element may be present, and should be interpreted as not excluding other elements but as including other elements. Furthermore, the terms "corresponding" used below may include at least one of the meanings of "opposite" or "overlapping."

However, other coordinate systems may also be used for explanation, and the embodiment is not limited thereto. In each drawing, the X-axis and Y-axis may refer to directions perpendicular to the Z-axis of the optical axis OA. Furthermore, the Z-axis direction, which is the direction of the optical axis OA, may be referred to as the "first direction," the X-axis direction as the "second direction," and the Y-axis direction as the "third direction." For example, the first direction may be a direction perpendicular to the imaging area of ​​the image sensor.

[0105] 1 to 12, a camera device 200 may include a fixed unit, an AF moving unit, an OIS operating unit (or vibration unit) 100, and a support unit. The operating unit 100 may be expressed interchangeably as a "moving unit" or an "operating unit."

[0106] The fixed portion may be a fixed element. That is, the fixed portion may not move in the optical axis direction. Alternatively, the fixed portion may not move or tilt in a direction perpendicular to the optical axis. Also, a structure coupled to the fixed portion may correspond to the fixed portion.

[0107] The fixing part may include the housing 210. The fixing part may include the cover member 300. For example, the fixing part may include a configuration disposed on or coupled to the housing 210 or the cover member 300. For example, the fixing part may include any one of the magnet 310, the magnetic body 32, and the movement suppressing part 80 disposed on the housing 210.

[0108] The AF moving unit can move in the optical axis direction relative to the fixed unit. For example, the AF moving unit can include a bobbin 110. In another embodiment, the AF moving unit can further include a structure (e.g., a magnet 130) coupled to the bobbin 110. In another embodiment, the AF moving unit can further include a lens module 400 (see FIG. 4) coupled to the bobbin 110.

[0109] The OIS operating unit 100 (see FIG. 2a) can move or tilt left and right relative to the fixed unit about a first axis (e.g., X-axis (e.g., pitch)) perpendicular to the optical axis. The OIS operating unit can also move or tilt left and right relative to the fixed unit about a second axis (e.g., Y-axis (e.g., yaw)) perpendicular to the optical axis.

[0110] For example, the OIS operation unit may include an AF movement unit. The OIS operation unit may also include an image sensor 810. The OIS operation unit may also include a circuit board 800 on which the image sensor 810 is disposed. The OIS operation unit may also include a sensor base 270 on which at least a portion of the circuit board 800 is disposed. The OIS operation unit may also include a holder 140 coupled to the sensor base 270. The OIS operation unit may be referred to as a first movement unit (or a first operation unit), and the AF movement unit may be referred to as a second movement unit (or a second operation unit). For example, the first movement unit may include the sensor base 270 and the circuit board 800.

[0111] For example, the OIS operating unit may include a configuration disposed on or coupled to any one of the holder 140, the sensor base 270, and the circuit board 800. For example, the OIS operating unit may include the coil 230 and the magnet 130 disposed on the holder 140. For example, the OIS operating unit may include the magnet 31 disposed on the sensor base 270. For example, the OIS operating unit may include any one of the image sensor 810, the sensors 170 and 240, the coils 120 and 230, the gyro sensor 820, the circuit element 815, and the control unit 830 disposed on the circuit board 800.

[0112] The support portion can support the OIS operating portion relative to the fixed portion, for example, the support portion can include a moving plate 60. For example, the support portion can include rolling members 62, 63.

[0113] The bobbin 110 is for housing a lens or a lens barrel and can be placed in the holder 140. The bobbin 110 can also be referred to interchangeably as a "lens holder" or a "lens carrier."

[0114] The bobbin 110 can move in the optical axis direction. For example, the bobbin 110 can move in a first direction (e.g., the Z-axis direction) due to 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 an AF moving unit.

[0115] The bobbin 110 is included in the OIS operating unit, and can tilt around a first axis or a second axis or rotate by a preset angle.

[0116] 5, the bobbin 110 may include an opening 101 for coupling with the lens module 400. The shape of the opening 101 of the bobbin 110 may match the shape of the lens module 400 to be attached, and may be, for example, but not limited to, a circle, an ellipse, or a polygon.

[0117] 1, the bobbin 110 may include at least one stopper disposed on at least one of the upper surface and the lower surface. The stopper of the bobbin 110 has a structure that protrudes in a first direction or upward (or downward) from the upper surface (or the lower surface) of the bobbin 110, and can prevent the upper surface of the bobbin 110 from directly hitting the inner surface of the upper plate 301 of the cover member 300 (or the lower part of the holder 140).

[0118] The bobbin 110 may include a seat 115 for seating or positioning the magnet 130. For example, the seat 115 may be a groove recessed from the outer surface of the bobbin 110.

[0119] 6, the bobbin 110 may include multiple 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.

[0120] For example, the second side surface 110B may face the first side surface 110A or may be located on the opposite side of the first side surface 110A relative to the optical axis OA. The third side surface 110C and the fourth side surface 110D may be located between the first side surface 110A and the second side surface 110B. For example, the fourth side surface 110D may face the third side surface 110C or may be located on the opposite side of the third side surface 110C relative to the optical axis OA. Although FIG. 6 illustrates a bobbin 110 including four sides, other embodiments may include three or five or more sides.

[0121] For example, the seat 115 may be formed on the first side 110A of the bobbin. For example, the lower portion of the seat 115 may be closed without opening at the lower surface of the bobbin 110. Also, the upper portion of the seat 115 may be closed without opening at the upper surface of the bobbin 110. In other embodiments, for example, the seat 115 may include an opening that opens at least at one of the upper surface or the lower surface of the bobbin 110.

[0122] The bobbin 110 may include a receiving portion 112 for receiving at least a portion of the rolling member 21. For example, at least a portion of the receiving portion 112 may be disposed on a first side surface 110A of the bobbin 110. The receiving portion 112 may be a groove recessed from an outer surface (e.g., the first side surface 110A) of the bobbin 110. The receiving portion 112 may be interchangeably expressed as an "accommodation groove," "groove," or "guide groove." A lubricant (e.g., grease) may be disposed within the receiving portion 112 of the bobbin 110 to reduce frictional force with the rolling member 21.

[0123] For example, the bobbin 110 may include a first receiving portion 112A for receiving the rolling member 21A and a second receiving portion 112B for receiving the rolling member 21B. For example, the seat 115 may be disposed between the first receiving portion 112A and the second receiving portion 112B.

[0124] For example, the first receiving portion 112A (or the second receiving portion 112B) may include an opening that opens to the top surface of the bobbin 110. In other embodiments, the tops of the receiving portions 112A and 112B may be closed without opening to the top surface of the bobbin 110. For example, the bottoms of the receiving portions 112A and 112B may be closed without opening to the bottom surface of the bobbin 110.

[0125] For example, the receiving portion 112 may be formed to extend in the optical axis direction. For example, the receiving portion 112 may be formed between the upper surface and the lower surface of the bobbin 110 and extend in the optical axis direction.

[0126] For example, when viewed from above, the shape of the housing 112 may be, but is not limited to, a triangular shape, and may be a polygon (e.g., a square or a pentagon, etc.). Alternatively, for example, when viewed from above, the housing 112 may have a "V" or "U" shape.

[0127] The magnet 130 may be disposed on, coupled to, or fixed to the bobbin 110. For example, the magnet 130 may be disposed on or coupled to the first side 110A of the bobbin 110. For example, the magnet 130 may be disposed within or coupled to the seat 115 of the bobbin 110. For example, the magnet 130 may be disposed between the first rolling member 21A and the second rolling member 21B.

[0128] The shape of the magnet 130 may be, for example, a rectangular parallelepiped shape that corresponds to the first side surface 110A of the bobbin 110. In another embodiment, for example, at least one of both ends of the magnet 130 may have a tapered shape.

[0129] 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.

[0130] Also, to increase the electromagnetic force, the magnet 130 can be a four-pole magnet, for example, the magnet 130 can include two north poles and two south poles.

[0131] For example, the magnet 130 may include a first magnet including a north pole and a south pole, a second magnet including a south pole and a north pole, and a partition wall disposed between the first and second magnets. Here, the partition wall is a substantially non-magnetic portion and may include a section with almost no polarity, and may be filled with air or made of a non-magnetic material, and may also be referred to as a "neutral zone." For example, the first and second magnets may face each other in the optical axis direction, and the first and second magnets may be disposed such that their opposite polarities face each other in the optical axis direction.

[0132] In other embodiments, magnet 130 may be a two-pole magnet with a naturally formed interface between two opposing polarities. For example, in other embodiments, magnet 130 may include one north pole and one south pole.

[0133] For example, magnet 130 may be a two-pole magnet divided into or arranged with a north pole and a south pole in the optical axis direction. In another embodiment, magnet 130 may be a magnet divided into or arranged with a north pole and a south pole in a direction perpendicular to the optical axis. In another embodiment, magnet 130 may be a two-pole magnet divided into a north pole and a south pole in a direction perpendicular to the optical axis.

[0134] The holder 140 may be disposed inside the cover member 300. The holder 140 may include a cavity for accommodating 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 a hollow for exposing at least a portion of the bobbin 110 (or the lens module 400). Also, 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 interchangeably as a "housing."

[0135] For example, the opening 30A may be located in the center or central region of the holder 140. For example, the opening 30A of the holder 140 may be a through-hole or a hollow that penetrates the holder 140 in the optical axis direction. The opening 30A of the holder 140 may have a shape that corresponds to the shape of the bobbin 110, for example, a polygonal shape (e.g., a square or an octagonal shape) or a circular shape (or an elliptical shape), but is not limited thereto, and may have various shapes.

[0136] The holder 140 may include a plurality of sides 41A to 41D. The holder 140 may include a corner located between and connecting two adjacent sides.

[0137] The holder 140 may include a first side 41A corresponding to or facing the first side 110A of the bobbin 110, a second side 41B corresponding to or facing the second side 110B of the bobbin 110, a third side 41C corresponding to or facing the third side 110C of the bobbin 110, and a fourth side 41D corresponding to or facing the fourth side 110D of the bobbin 110.

[0138] The first side 41A (or first side surface or first outer surface) of the holder 140 may be located on the opposite side of the second side 41B (or second side surface or second outer surface) of the holder 140 based on the optical axis, and the third side 41C (or third side surface or third outer surface) of the holder 140 may be located on the opposite side of the fourth side 41D (or fourth side surface or fourth outer surface) of the holder 140 based on the optical axis.

[0139] Each of the first to fourth side portions 41A to 41D of the holder 140 may be disposed parallel to a corresponding one of the side plates 302 of the cover member 300.

[0140] 7a and 7b, the holder 140 may include a seat 142A for disposing the coil 120. For example, the seat 142A may be disposed or formed on the first side 41A of the holder 140. For example, the seat 142A may be a through-hole that penetrates the first side 41A of the holder 140. Because the seat 142A is in the form of a through-hole, no part of the holder 140 is interposed between the coil 120 and the magnet 130, thereby increasing the electromagnetic force between the magnet 130 and the coil 120. In addition, because no part of the holder 140 is interposed between the position sensor 170 and the magnet 130, the output of the position sensor 170 may be increased, thereby improving the sensitivity of the position sensor 170.

[0141] In another embodiment, the seat 142A may be a groove recessed from the outer surface (or inner surface) of the first side 41A of the holder 140.

[0142] The holder 140 may include seats 143A and 143B for placing the coil 230. For example, the holder 140 may include a first seat 143A for placing the first coil unit 230A and a second seat 143B for placing the second coil unit 230B.

[0143] For example, the first seat 143A may be disposed or formed on the second side 41B of the holder 140. For example, the first seat 143A may be a through-hole formed through the second side 41B of the holder 140.

[0144] For example, the second seat 143B may be disposed or formed on the third side 41C of the holder 140. For example, the second seat 143B may be a through-hole formed through the third side 41C of the holder 140.

[0145] Since the seating portions 143A and 143B are in the form of through holes, no part of the holder 140 is interposed between the coil 230 and the magnet 310, thereby increasing the electromagnetic force between the magnet 310 and the coil 230. In addition, since no part of the holder 140 is interposed between the position sensor 240 and the magnet 310, the output of the position sensor 240 can be increased, thereby improving the sensitivity of the position sensor 240.

[0146] In another embodiment, the first seating portion 143A may be a groove recessed from the outer surface (or inner surface) of the second side portion 41B of the holder 140, and the second seating portion 143B may be a groove recessed from the outer surface (or inner surface) of the third side portion 41C of the holder 140.

[0147] For example, the holder 140 may include a groove 142 into which at least a portion of the first extension 802A of the circuit board 800 is disposed. Since at least a portion of the first extension 802A is disposed in the groove 142 of the holder 140, the first extension 802A and the magnetic material 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.

[0148] That is, the first extension 802A and the magnetic body 82 may protrude from the outer surface of the first side 41A of the holder 140 by a distance smaller than the sum of the thickness of the first extension 802A and the thickness of the magnetic body 82. Therefore, it is possible to prevent the size of the camera device 200 from increasing in the direction perpendicular to the optical axis.

[0149] 7a and 7b, the holder 140 may include a receiving portion 116 for disposing or receiving at least a portion of the rolling member 21. For example, at least a portion of the receiving portion 116 may be disposed on the first side portion 41A of the holder 140. The receiving portion 116 may be a groove recessed from the inner surface of the holder 140 (e.g., the inner surface of the first side portion 41A). The receiving portion 116 may also be referred to as an "accommodating groove," "groove," or "guide groove."

[0150] 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 .

[0151] For example, the holder 140 may include a first receiving portion 116A for receiving at least another portion of the first rolling members B1 and B2 and a second receiving portion 116B for receiving at least another portion of the second rolling members B3 and B4. For example, the seating portion 142A of the holder 140 may be disposed between the first receiving portion 116A and the second receiving portion 116B of the holder 140.

[0152] For example, the first receiving portion 116A (or the second receiving portion 116B) may include an opening that opens to the top surface of the holder 140. In other embodiments, the top of the receiving portion 116 may be closed without opening to the top surface of the holder 140. For example, the bottom of the receiving portion 116 may be closed without opening to the bottom surface of the holder 140.

[0153] For example, the receiving portion 116 may be formed to extend in the optical axis direction. For example, the receiving portion 116 may be formed between the upper surface and the lower surface of the holder 140 and extend in the optical axis direction.

[0154] For example, when viewed from above, the shape of the receiving portion 116 of the holder 140 may be, but is not limited to, a triangular shape, and may be a polygonal shape (e.g., a square or a pentagon, etc.). Alternatively, for example, when viewed from above, the receiving portion 116 may be "V" shaped or "U" shaped.

[0155] For example, when viewed in the optical axis direction or from above, the receiving portion 116 may face or overlap 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.

[0156] The camera device 200 may include a rolling member 21 disposed between the bobbin 110 and the holder 140. The rolling member 21 may be interchangeably expressed as a "ball member," a "ball," or a "ball bearing."

[0157] At least a portion of the rolling member 21 can contact the bobbin 110 and the holder 140, and can support movement of the bobbin 110 in the optical axis direction by rolling or rotating between the bobbin 110 and the holder 140. When the bobbin 110 moves in the optical axis direction, the rolling member 21 can reduce friction between the bobbin 110 and the holder 140. The rolling or rotation of the rolling member 21 allows the bobbin 110 to slide or glide in the optical axis direction while contacting the rolling member 21.

[0158] For example, the rolling member 21 may be made of, but is not limited to, a metal material, a plastic material, or a resin material. The rolling member 21 may have a circular shape and a diameter large enough to support the movement of the bobbin 110 in the optical axis direction.

[0159] For example, the rolling member 21 may be disposed between the outer surface of the bobbin 110 and the inner surface of the holder 140. For example, the rolling member 21 may be disposed between the first side surface 110A of the bobbin 110 and the first side 41A of the holder 140. For example, the rolling member 21 may be disposed between the receiving portion 112 of the bobbin 110 and the receiving portion 116 of the holder 140.

[0160] For example, at least a portion of the rolling member 21 may contact the receiving portion 112 of the bobbin 110 , and at least another portion of the rolling member 21 may contact the receiving portion 116 of the holder 140 .

[0161] The rolling member 21 may include at least one ball member. For example, the rolling member 21 may include two or more ball members B1 to B4.

[0162] For example, the rolling member 21 may include a first rolling member 21A disposed between the first receiving portion 112A of the bobbin 110 and the first receiving portion 116A of the holder 140, and a second rolling member 21B 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 rolling member 21A may include at least one ball. For example, the first rolling member 21A may include a plurality of balls B1 and B2.

[0163] The second rolling member 21B may include at least one ball. For example, the second rolling member 21B may include a plurality of balls B3 and B4. In other embodiments, the first rolling member 21A and the second rolling member 21B may each include one ball.

[0164] For example, each of the first rolling member 21A and the second rolling member 21B may include three or more balls. For example, each of the first rolling member 21A and the second rolling member 21B may include a highest ball located at the top, a lowest ball located at the bottom, and at least one intermediate ball located between the highest and lowest balls. For example, the diameter of the highest 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 highest ball and the lowest ball may be the same. In another embodiment, the diameters of the highest ball, the lowest ball, and the intermediate ball may be the same.

[0165] For example, each of the first rolling member 21A and the second rolling member 21B may include a first ball (highest ball), a second ball (lowest ball), and a third ball (middle ball) arranged in the optical axis direction, and the diameter of the first ball may be larger than the diameter of the third ball. Also, the diameter of the second ball may be larger than the diameter of the third ball. For example, the diameters of the first ball and the third ball may be the same. In another embodiment, the diameter of the first ball may be larger than the diameter of the second ball. In yet another embodiment, the diameter of the first ball may be smaller than the diameter of the second ball. In yet another embodiment, the diameters of the first ball, the second ball, and the third ball may be the same.

[0166] For example, the diameter of the first ball and the diameter of the second ball may each be 0.85 mm or more and 0.95 mm or less, and the diameter of the third ball may be 0.75 mm or more and 0.85 mm or less.

[0167] In yet another embodiment, each of the first rolling member 21A and the second rolling member 21B may include four balls, the diameter of the highest ball and the diameter of the lowest ball may be 0.85 mm or more and 0.95 mm or less, and the diameter of each of the two intermediate balls may be 0.75 mm or more and 0.85 mm or less.

[0168] When viewed from above, the coil 120 and the magnet 130 may be located between the first rolling member 21A and the second rolling member 21B. This is because, when the bobbin 110 moves in the optical axis direction, the rolling members 21 stably support the bobbin 110 without tilting or moving, thereby improving the reliability of autofocusing.

[0169] The camera device 200 may include a magnetic body 82 that exerts an attractive force on the magnet 130. For example, an attractive force may act between the magnetic body 82 and the magnet 130 in a direction perpendicular to the optical axis (or a second direction). For example, the magnetic body 82 may be disposed in the holder 140. In another embodiment, the magnetic body 82 may be disposed in the housing 210.

[0170] 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 metal material that is attracted to a magnet. Alternatively, for example, the magnetic body 82 may be made of a metal material that has magnetic properties. Alternatively, for example, the magnetic body 82 may be a magnet. The magnetic body 82 may be expressed interchangeably as a "yoke." The magnetic body 82 may also serve to increase or enhance the electromagnetic force between the magnet 130 and the coil 120.

[0171] Since the magnet 130 is disposed on the bobbin 110 and the magnetic body 82 is disposed on the holder 140, the bobbin 110 is pulled in the direction of the holder 140 on which the magnetic body 82 is disposed due to the attractive force acting between the magnetic body 82 and the magnet 130. The attractive force between the magnetic body 82 and the magnet 130 allows the bobbin 110 and the holder 140 to press the rolling member 21, and the bobbin 110 can be stably supported.

[0172] The magnetic body 82 and the magnet 130 may be a "pressing unit" or a "pressing member." Such a pressing unit can maintain contact between the bobbin 110 and the rolling member 21 and between the holder 140 and the rolling member 21 when the bobbin 110 moves in the optical axis direction. That is, the attractive force between the magnet 130 and the magnetic body 82 allows the rolling member 21 to stably support the bobbin 110 relative to the holder 140.

[0173] In another embodiment, the magnet 130 may be disposed on the holder 140, and the coil 120 may be disposed on the bobbin 110. For example, the magnetic body 82 may be disposed on the holder 140 together with the magnet 130. For example, the magnet 130 may be disposed between the magnetic body 82 and the coil 120. In yet another embodiment, the magnetic body 82 may be disposed on the bobbin 110 together with the coil 120, facing the magnet 130 disposed on the holder 140. In addition, the camera device 200 may further include a current-carrying member, for example, a conductive member, for electrically connecting the coil 120 disposed on the bobbin 110 and the second board 802 of the circuit board 800.

[0174] 7b, the holder 140 may include a seat 45A for seating or positioning the filter 610. The seat 45A may be disposed on or formed on the lower surface of the holder 140. For example, the seat 45A may be a groove recessed from the lower surface of the holder 140. For example, the seat 45A may include a bottom surface 5A that is stepped in the optical axis direction relative to the lower surface of the holder 140, and a side surface 5B that connects the lower surface of the holder 140 and the bottom surface 5A of the seat 45A. For example, an opening 30A may be formed through the bottom surface 5A of the seat 45A.

[0175] The holder 140 may include a recess 45B disposed or formed in a corner region of the inner surface of the seat 45A. The recess 45B may have a recessed structure in a direction from the optical axis toward the corner region of the inner surface of the seat 45A. The recess 45B may prevent an adhesive (e.g., UV epoxy) used to attach or bond the filter 610 to the seat 45A from overflowing outside the seat 45A.

[0176] The holder 140 may include an escape groove 46 for avoiding spatial interference with the circuit element 815. For example, the escape groove 46 may be disposed or formed on the lower surface of the holder 140. For example, the escape groove 46 may be recessed from the lower surface of the holder 140.

[0177] The escape groove 46 may correspond to, face, or overlap with the circuit element 815 in the optical axis direction. For example, the escape groove 46 may be located between the seating portion 45A and an edge of the lower surface of the holder 140. For example, the escape groove 46 may include a first escape groove 46A and a second escape groove 46B located on opposite sides of the seating portion 45A or the filter 610. In another embodiment, the escape groove 46 may include four escape grooves located between the opening 30A and the four edges of the holder 140.

[0178] The holder 140 may include a groove 47 corresponding to the protrusion 216 of the sensor base 270. The protrusion 216 of the sensor base 270 and the groove 47 of the holder 140 may serve as a guide for easily assembling the sensor base 270 and the holder 140, and may increase the bonding area and thereby increase the bonding strength between the sensor base 270 and the holder 140.

[0179] For example, the groove 47 may be recessed from the bottom surface of the holder 140. For example, the groove 47 may be disposed or formed in a corner or corner region of the bottom surface of the holder 140. The groove 47 of the holder 140 may have a shape corresponding to the protrusion 216 of the sensor base 270. The holder 140 may also include a groove 48 or hole corresponding to the protrusion 17 of the sensor base 270. For example, the protrusion 17 of the sensor base 270 may be inserted into or coupled with the groove 48 of the holder 140. For example, the groove 48 may be disposed or formed in the bottom surface of the groove 47 of the holder 140. For example, the groove 48 may be recessed from the bottom surface of the groove 47 of the holder 140.

[0180] In another embodiment, holder 140 may include a protrusion protruding from the bottom surface of holder 140 instead of groove 47, and sensor base 270 may include a groove recessed from the top surface of sensor base 270 and coupled with the protrusion of holder 140 instead of protrusion 216. In yet another embodiment, protrusion 17 may be formed on holder 140, and groove 48 may be formed on sensor base 270.

[0181] Camera device 200 may include filter 610 disposed on or coupled to holder 140. For example, filter 610 may be disposed below holder 140. For example, filter 610 may be coupled to the underside of holder 140. For example, filter 610 may be disposed on seat 45A of holder 140.

[0182] The filter 610 may serve to block light of a specific frequency band from passing through the lens module 400 from entering the image sensor 810. For example, the filter 610 may be an infrared blocking filter. For example, the filter 610 may be disposed parallel to a plane perpendicular to the optical axis OA.

[0183] The filter 610 can be bonded to the holder 140 (or seat 45A) by an adhesive (not shown). For example, an edge region of the filter 610 can be bonded to the bottom surface of the seat 45A.

[0184] For example, the adhesive may be an epoxy, a heat-curable adhesive, an ultraviolet-curable adhesive, etc. For example, at least a portion of the filter 610 may correspond to, face, or overlap with the lens module 400 and / or the image sensor 810 in the optical axis direction.

[0185] The sensor base 270 may be disposed below the holder 140. The sensor base 270 may be coupled to the holder 140. The sensor base 270 may be interchangeably referred to as a "holder." The holder 140 may also be interchangeably referred to as a "first housing" (or a "first holder"), and the sensor base 270 may also be interchangeably referred to as a "second housing" (or a "second holder"). The holder 140 and the sensor base 270 may not be interchangeably referred to as separate components, but may be interchangeably referred to as a single term, such as a "housing," "holder," or "sensor base." In another embodiment, the sensor base 270 and the holder 140 may be integrally formed.

[0186] For example, the sensor base 270 may include a protrusion 216 that protrudes from the upper surface. The protrusion 216 may be expressed interchangeably as a "pillar."

[0187] For example, the protrusion 216 may correspond to, face, or overlap with the groove 47 of the holder 140 in the optical axis direction. At least a portion of the protrusion 216 of the sensor base 270 may be inserted into the groove 47 of the holder 140. For example, at least a portion of the protrusion 216 may be coupled with the groove 47 of the holder 140. For example, at least a portion of the protrusion 216 may be coupled with the groove 47 of the holder 140 by an adhesive.

[0188] For example, the sensor base 270 may include a body 270A and a protrusion 216 protruding from an upper surface of the body 270A. For example, the body 270A may have a shape corresponding to the first board 801 of the circuit board 800. For example, the body 270A may have a polyhedral, e.g., hexahedral, shape. For example, the protrusion 216 may be disposed in a corner region of the upper surface of the body 270A. For example, the protrusion 216 may include four protrusions 216A to 216D disposed in four corner regions of the upper surface of the body 270A. Also, for example, the holder 140 may include four grooves 47 corresponding to the four protrusions 216A to 216D. In another embodiment, the housing 210 may include at least one protrusion disposed in at least one of the four corner regions of the upper surface of the body 270, and the holder 140 may include at least one groove 48 corresponding to the at least one protrusion of the housing 210.

[0189] The sensor base 270 or body 270A can include sides 51A-51D that correspond to, face, or overlap sides 41A-41D of the holder 140.

[0190] The sensor base 270 may include a receiving portion 56 in which the gyro sensor 820 is disposed or to avoid spatial interference with the gyro sensor 820. For example, the receiving portion 56 may be provided to penetrate the sensor base 270 in the optical axis direction. For example, the receiving portion 56 may be provided to penetrate the body 270A in the optical axis direction. In another embodiment, the receiving portion 56 may be a groove recessed from the top surface of the body 270A. The receiving portion 56 may include an opening that opens to the outer surface of the sensor base 270.

[0191] The sensor base 270 may include a receiving portion 155 in which the control unit 830 is disposed or for receiving the control unit 830. The receiving portion 155 may be a groove recessed from the lower surface of the sensor base 270 or the lower surface of the body 270A. In another embodiment, the receiving portion 155 may be a through-hole formed through the sensor base 270 or the body 270A in the optical axis direction.

[0192] The sensor base 270 may include a receiving portion 28A for receiving the magnet 31. The receiving portion 28A may be disposed or formed on the lower portion or bottom surface of the sensor base 270. For example, the receiving portion 28A may be a groove recessed from the lower portion or bottom surface of the sensor base 270. For example, the receiving portion 28A may be disposed or formed on the bottom surface of the body 270A. For example, the receiving portion 28A may have a shape corresponding to the magnet 31.

[0193] In an embodiment in which the positions of the magnetic body 32 and the magnet 31 are reversed, the magnetic body 32 may be disposed in the receiving portion 28A of the sensor base 270 and the magnet 31 may be disposed in the receiving portion 49A of the housing 210.

[0194] The sensor base 270 may include a seat 25A on which at least a portion of the moving plate 60 is disposed or for accommodating at least a portion of the moving plate 60. For example, the seat 25A may be a groove recessed from the lower surface of the sensor base 270. For example, the seat 25A may have a shape that corresponds to or matches the shape of the moving plate 60. For example, the seat 25A may include a bottom surface that is stepped in the optical axis direction relative to the lower surface of the sensor base 270, and a side surface that connects the bottom surface to the lower surface of the sensor base 270. For example, the bottom surface of the seat 25A may be positioned higher than the lower surface of the sensor base 270.

[0195] 4a and 4b, a seat 25A for inserting or positioning at least a portion of the moving plate 60 is formed on the underside of the sensor base 270, and the sensor base 270 may include a partition (or guide portion) 272 disposed on the underside and arranged around the moving plate 60. The moving plate 60 may be spaced apart from the partition 272, and the partition 272 may be arranged to surround the moving plate 60. The partition 272 may prevent the moving plate 60 from detaching or falling off the sensor base 270.

[0196] The sensor base 270 may include a protrusion (or projection) 28 protruding from the lower portion or bottom surface of the sensor base 270. For example, the protrusion 28 may protrude from the bottom surface of the seat 25A of the sensor base 270. For example, the protrusion length of the protrusion 28 may be greater than the depth of the seat 25A. For example, the protrusion length of the protrusion 28 may be the distance (or shortest distance) from the bottom surface of the seat 25A to the bottom surface (or lowest end) of the protrusion 28. Also, the depth of the seat 25A may be the distance (or shortest distance) from the bottom surface of the sensor base 270 to the bottom surface of the seat 25A. In other embodiments, for example, the protrusion length of the protrusion 28 may be less than or equal to the depth of the seat 25A. For example, the protrusion 28 may have a shape that corresponds to or matches the opening 60A of the moving plate 60.

[0197] For example, the protrusion 28 of the sensor base 270 may correspond to, face, or overlap with the opening 60A of the moving plate 60 in the optical axis direction. For example, at least a portion of the protrusion 28 of the sensor base 270 may be disposed within the opening 60A of the moving plate 60.

[0198] For example, the receiving portion 28A may be disposed or formed in the protruding portion 28 of the sensor base 270. For example, the receiving portion 28A may be a groove recessed from the lower surface of the protruding portion 28 of the sensor base 270.

[0199] For example, the protrusion 28 may be disposed between the ball members 62A and 62B. For example, the protrusion 28 (or the magnet 31) may overlap the ball members 62A and 62B in a direction perpendicular to the optical axis, for example, in the second direction.

[0200] The sensor base 270 may include grooves 29 in which the rolling members 62 are disposed or for accommodating the rolling members 62. The grooves 29 may be formed on the lower surface of the sensor base 270. For example, the grooves 29 may be recessed from the lower surface of the sensor base 270. The number of grooves 29 may be the same as the number of rolling members 62.

[0201] For example, the groove 29 may include two grooves 29A and 29B spaced apart from each other. For example, the two grooves 29A and 29B may be spaced apart from each other in the X-axis direction. For example, the protrusion 28 of the sensor base 270 may be disposed between the two grooves 29A and 29B of the sensor base 270.

[0202] The groove 29 may contact the rolling member 62 at at least one point. For example, the groove 29 may include a bottom surface and at least one side surface connected to the bottom surface. The at least one side surface may be an inclined surface. For example, the groove 29 may include a bottom surface and multiple inclined surfaces. The shapes of the inclined surfaces of the groove 29 may be the same as each other. In other embodiments, at least one of the inclined surfaces of the groove 29 may have a different shape from the rest.

[0203] 7c, a groove 212A into which at least a portion of a first substrate 801 of a circuit board 800 is inserted or disposed may be formed in the protrusion 216 of the sensor base 270. 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 that faces the corner of the circuit board 800. In addition, a groove 83 for being inserted into or coupled with the groove 212A of the protrusion 216 may be formed in at least one corner of the circuit board 800. The groove 212A of the protrusion 216 of the sensor base 270 serves as a coupling guide for coupling the first substrate 801 and the sensor base 270 and may serve to prevent the first substrate 801 from rotating or separating from the sensor base 270.

[0204] The circuit board 800 may be disposed on, coupled to, 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 fastening member.

[0205] The circuit board 800 may be disposed on, coupled to, or fixed to the body 270A of the sensor base 270. The circuit board 800 may include any one of a rigid printed circuit board (Rigid PCB), a flexible printed circuit board (Flexible PCB), and a rigid-flexible printed circuit board (RigidFlexible PCB). For example, the circuit board 800 may include a rigid printed circuit board and a flexible printed circuit board. The circuit board 800 may be referred to as a "board unit," a "board," or a "printed circuit board."

[0206] For example, the circuit board 800 may include a first substrate (or "first region") 801 disposed on, coupled to, or fixed to the sensor base 270. For example, the first substrate 801 may be disposed on, coupled to, or fixed to the body 270A of the sensor base 270. For example, the bottom surface of the first substrate 801 may be coupled to the top surface of the sensor base 270 or the top surface of the body 270A. For example, the bottom surface of the first substrate 801 may be coupled to the top surface of the sensor base 270 or the top surface of the body 270A by adhesive.

[0207] The circuit board 800 may include a second board (or "second region") 802 coupled to the first board 801 and disposed on the side of the holder 140. The second board 802 may include multiple portions (or "extensions") 802A to 802C.

[0208] For example, the second substrate 802 may include a first extension 802A that is disposed on, coupled to, or fixed to the first side 41A of the holder 140. The second substrate 802 may also include a second extension 802B that is disposed on, coupled to, or fixed to the second side 41B of the holder 140. The second substrate 802 may also include a third extension 802C that is disposed on, coupled to, or fixed to the third side 41C of the holder 140.

[0209] For example, the first extension 802A may be connected to a first side of the first substrate 801, the second extension 802B may be connected to a second side of the first substrate 801 opposite the first side, and the third extension 802C may be connected to a third side of the first substrate 801 between the first and second sides. For example, each of the first to third extensions 802A to 802C may be bent from a corresponding one of the first to third sides of the first substrate 801. Each of the first to third extensions 802A to 802C may extend upward from the first substrate 801.

[0210] The circuit board 800 may include a third board 803 on which a connector 805 is arranged or provided, and a fourth board 804 that connects the first board 802 and the third board 803 together.

[0211] For example, the first substrate 801 may be a rigid printed circuit board. For example, the second substrate 802 may be a flexible printed circuit board. 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.

[0212] For example, a rigid printed circuit board may include a plurality of conductive layers (or circuit patterns) spaced apart in the optical axis direction and an insulating layer disposed between two adjacent conductive layers among the plurality of conductive layers. For example, a flexible printed circuit board may include one conductive layer (or circuit pattern) and a second insulating layer disposed below a first insulating conductive layer disposed on the conductive layer. In another embodiment, a flexible printed circuit board may include a first conductive layer, a second conductive layer, 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.

[0213] The image sensor 810 may be disposed on the first substrate 801. The image sensor 810 may be disposed to correspond to, face, or overlap the lens module 400 and / or the filter 610 in the optical axis direction.

[0214] The image sensor 810 may include an imaging area for sensing light. Here, the imaging area may be alternatively referred to as an effective area, a light-receiving area, or an active area. For example, the imaging area may include a number of pixels on which an image is formed. The image sensor 810 may be conductively or electrically connected to the first substrate 801. The imaging area may correspond to, face, or overlap with the lens module 400 and / or the filter 610 in the optical axis direction.

[0215] The camera device 200 may include a circuit element 815 disposed on 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, or a driver IC), or a circuit pattern. For example, 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.

[0216] The camera device 200 may include a control unit 830 disposed on the circuit board 800. For example, the control unit 830 may be a driver IC. For example, the control unit 830 may be disposed on the first substrate 801. For example, the control unit 830 may be disposed below the first substrate 801. For example, the control unit 830 may be disposed on, coupled to, or fixed to the lower surface of the first substrate 801. For example, the control unit 830 may be conductively or electrically connected to the first substrate 801.

[0217] For example, the control unit 830 is electrically connected to the coil 120 and can supply a drive signal to the first coil 120. The control unit 830 is electrically connected to the coil units 230A and 230B and can supply a first drive signal to the first coil unit 230A and a second drive signal to the second coil unit 230B.

[0218] The control unit 830 may be conductively or electrically connected to the position sensor 170. The control unit 830 may also be conductively or electrically connected to the position sensor 240.

[0219] For example, the control unit 830 can receive the output signal of the position sensor 170 and can control the drive signal (eg, drive current) supplied to the coil 120 using the output signal of the position sensor 170 .

[0220] For example, the control unit 830 can receive an output signal of the position sensor 240 and use the output signal of the position sensor 240 to control a drive signal (e.g., a drive current) supplied to the coil 230. For example, the control unit 830 can receive an output signal of the first sensor 240A and use the output signal of the first sensor 240A to control a first drive signal (e.g., a first drive current) supplied to the first coil unit 230A. Furthermore, the control unit 830 can receive an output signal of the second sensor 240B and use the output signal of the second sensor 240B to control a second drive signal (e.g., a second drive current) supplied to the second coil unit 230B.

[0221] The camera device 200 may include a gyro sensor 820 disposed on the circuit board 800. For example, the gyro sensor 820 outputs rotational angular velocity information according to the operation of the camera device 200. For example, the gyro sensor 820 may be implemented by a two-axis or three-axis gyro sensor or an angular velocity sensor.

[0222] For example, the gyro sensor 820 may be disposed on the first substrate 801. For example, the gyro sensor 820 may be disposed below the first substrate 801. For example, the gyro sensor 820 may be disposed on, coupled to, or fixed to the lower surface of the first substrate 801. For example, the gyro sensor 820 may be conductively or electrically connected to the first substrate 801.

[0223] For example, one of the gyro sensor 820 and the control unit 830 may be disposed near the third substrate 803. For example, one of the gyro sensor 820 and the control unit 830 may be disposed near a first side surface of the first substrate 801 that is adjacent to or connected to the third substrate 803. The gyro sensor 820 and the control unit 830 may be disposed closer to the first side surface of the first substrate 801 than to a second side surface of the first substrate 801, and the second side surface of the first substrate 801 may be located opposite the first side surface of the first substrate 801.

[0224] The coils 120, 230 may be disposed on, coupled to, or fixed to the circuit board 800 (e.g., the second board 802). For example, the coils 120, 230 may be conductively or electrically connected to the circuit board 800 (e.g., the second board 802). For example, the coils 120, 230 may be conductively or electrically connected to the circuit board 800 (e.g., the second board 802) by a conductive adhesive or solder.

[0225] For example, the coil 120 may be disposed on or coupled to a first extension 802A of the second substrate 802 and be conductively or electrically connected to the first extension 802A. The first coil unit 230A may be disposed on or coupled to a second extension 802B of the second substrate 802 and be conductively or electrically connected to the second extension 802B. The second coil unit 230B may be disposed on or coupled to a third extension 802C of the second substrate 802 and be conductively or electrically connected to the third extension 802C.

[0226] The coil 120 can move an AF moving part (for example, a bobbin) in the optical axis direction by interacting with the magnet 130. The coil 120 can be placed on a holder 140.

[0227] The coil 120 may be arranged to correspond to, face, or overlap with the magnet 130 in a direction perpendicular to the optical axis. For example, the coil 120 may be arranged on the holder 140 to correspond to, face, or overlap with the magnet 130 in a second direction (e.g., the X-axis direction) or in a direction from the first side 41A to the second side 41B of the holder 140. For example, the coil 120 may be arranged on the first side 41A of the holder 140. The coil 120 may be arranged within the seating portion 142A of the holder 140.

[0228] For example, the coil 120 may include a hollow or a hole. For example, the coil 120 may have a ring shape or a closed curve shape. For example, the coil 120 may be 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 portion 41A of the holder 140. For example, the coil 120 may be a ring shape whose length in the horizontal direction (or third direction) is longer than its length in the vertical direction (or optical axis direction).

[0229] A drive signal may be applied to the coil 120 to generate an electromagnetic force through electromagnetic interaction with the magnet 130. For example, the drive signal may be applied to the coil 120 from the circuit board 800 or the control unit 830. Here, the drive signal supplied to the coil 120 may be direct current and may be in the form of a voltage or current. Alternatively, in other embodiments, for example, the drive signal provided to the coil 120 may include at least one of a direct current signal and an alternating current signal.

[0230] The coil 120 to which the driving signal is provided can electromagnetically interact with the magnet 130 disposed on the bobbin 110, and the AF movement unit can move in the first direction due to the electromagnetic force generated by the electromagnetic interaction between the coil 120 and the magnet 130. The control unit 830 can control the movement of the AF movement unit in the first direction by adjusting the magnitude and / or direction of the driving signal (e.g., driving current), thereby performing an autofocusing function.

[0231] For AF feedback drive, the camera device 200 may include a position sensor 170. The position sensor 170 may sense the position or displacement of the bobbin 110 in the optical axis direction. For example, the position sensor 170 may sense the magnet 130 disposed on the bobbin 110. In another embodiment, a sensing magnet facing the position sensor 170 may be disposed on the bobbin, separate from the magnet 130, and the position sensor 170 may sense the sensing magnet or the magnetic field of the sensing magnet to detect the displacement of the bobbin.

[0232] For example, the position sensor 170 may be disposed in the holder 140. For example, the position sensor 170 may be disposed on the first side 41A of the holder 140. For example, the position sensor 170 may be disposed in the seat 142A of the holder 140. For example, the position sensor 170 may be disposed in the hollow of the coil 120. In other embodiments, the position sensor 170 may be disposed outside the hollow of the coil 120.

[0233] 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 first extension 802A of the second board 802. For example, the position sensor 170 may be conductively or electrically connected to the first extension 802A by a conductive adhesive or solder.

[0234] For example, the position sensor 170 may be disposed on, coupled to, or fixed to a first surface of the first extension portion 802A. For example, the position sensor 170 may correspond to, face, or overlap with the magnet 130 in a direction perpendicular to the optical axis or in a second direction.

[0235] The position sensor 170 can sense the displacement of the bobbin 110 in the optical axis direction.

[0236] For example, the position sensor 170 can sense the magnetic field or the strength of the magnetic field of the magnet 130 attached to the bobbin 110 due to the movement of the bobbin 110, and can output an output signal.

[0237] For example, the position sensor 170 may be a Hall sensor. Here, 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 two output terminals of the position sensor 170. The circuit board 800 or the control unit 830 may supply a driving signal to the two input terminals of the position sensor 170, and the output signals output from the two output terminals of the position sensor 170 may be transmitted to the circuit board 800 or the control unit 830.

[0238] In another embodiment, the position sensor 170 may be implemented in the form of a driver IC including a Hall sensor. For example, if the position sensor 170 is a driver IC including a Hall sensor, the position sensor 170 may transmit and receive data to and from the outside using data communication using a protocol, for example, I2C communication.

[0239] For example, if the position sensor 170 is a driver IC including a Hall sensor, the position sensor 170 may include first and second terminals for receiving a power supply or a 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.

[0240] The coil 230, through interaction with the magnet 310 arranged in the housing 210, which is the fixed part, can tilt the OIS operating part or rotate it by a predetermined angle based on a first axis (e.g., X-axis) or a second axis (e.g., Y-axis).

[0241] The coil 230 may include a first coil unit 230A that corresponds to, faces, or overlaps with the first magnet unit 310A, and a second coil unit 230B that corresponds to, faces, or overlaps with the second magnet unit 310B.

[0242] For example, the first coil unit 230A may correspond to, face, or overlap with the first magnet unit 310A in the second direction, and the second coil unit 230B may correspond to, face, or overlap with the second magnet unit 310B in the third direction. For example, the first coil unit 230A may face or overlap with the coil 120 in the second direction.

[0243] For example, the first coil unit 230A may be disposed on the second side 41B of the holder 140, and the second coil unit 230B may be disposed on the third side 41C of the holder 140.

[0244] For example, each of the first and second coil units 230A, 230B may be hollow or include 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, the first coil unit 230A may be ring-shaped wound around a straight line perpendicular to the optical axis OA and perpendicular to the outer surface of the second side portion 41B of the holder 140, and the second coil unit 230B may be ring-shaped wound around a straight line perpendicular to the optical axis OA and perpendicular to the outer surface of the third side portion 41C of the holder 140. For example, each of the first and second coil units 230A, 230B may be ring-shaped with a longer length in the horizontal direction (or third direction) than in the vertical direction (or optical axis direction).

[0245] For OIS feedback driving, the camera device 200 may include a position sensor 240. The position sensor 240 may sense the displacement or angular displacement of the OIS operating unit due to tilting or rotation of the OIS operating unit.

[0246] For example, the position sensor 240 may include a first sensor 240A and a second sensor 240B. For example, the first sensor 240A may correspond to, face, or overlap with the first magnet unit 310A, and the second sensor 240B may correspond to, face, or overlap with the second magnet unit 310B. For example, at least a portion of the first sensor 240A may correspond to, face, or overlap with at least a portion of the first magnet unit 310A in the second direction. For example, the center of the first sensor 240A may overlap with the first magnet unit 310A in the second direction. At least a portion of the second sensor 240B may correspond to, face, or overlap with at least a portion of the second magnet unit 310B in the third direction. For example, the center of the second sensor 240A may overlap with the second magnet unit 310B in the third direction.

[0247] For example, the first sensor 240A can sense the first magnet unit 310A (or the magnetic field of the first magnet unit 310A). For example, the second sensor 240B can sense the second magnet unit 310B (or the magnetic field of the second magnet unit 310B).

[0248] For example, the first sensor 240A may be disposed on, coupled to, or fixed to the second extension 802B of the circuit board 800, and the second sensor 240B may be disposed on, coupled to, or fixed to the third extension 802C of the circuit board 800. For example, the first sensor 240A may be conductively or electrically connected to the second extension 802B, and the second sensor 240B may be conductively or electrically connected to the third extension 802C.

[0249] For example, the first sensor 240A may be disposed within the hollow (or hole) of the first coil unit 230A, and the second sensor 240B may be disposed within the hollow (or hole) of the second coil unit 230B. In other embodiments, the first sensor 240A may be disposed outside the hollow (or hole) of the first coil unit 230A, and the second sensor 240B may be disposed outside the hollow (or hole) of the second coil unit 230B.

[0250] For example, each of the first sensor 240A and the second sensor 240B may 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 second extension 802B, 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 third extension 802C.

[0251] For example, the second extension 802B 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, which may be transmitted to the second extension 802B or the control unit 830. The first output signal may be output to the first and second output terminals of the first sensor 240A.

[0252] For example, the third extension 802C or the control unit 830 may supply or apply a second drive signal to the first and second input terminals of the second sensor 240B. The second sensor 240B may output a second output signal, which may be transmitted to the third extension 802C or the control unit 830. The second output signal may be output to the first and second output terminals of the second sensor 240B.

[0253] 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 can be applied or analogously applied to the embodiment in which the first and second sensors 240A and 240B are driver ICs including Hall sensors.

[0254] The camera device 200 may include a magnetic body 82 disposed opposite the coil 120 and the magnet 130. For example, the magnetic body 82 may be disposed on the holder 140 or the second substrate 802 of the circuit board 800. For example, the magnetic body 82 may be disposed so as to correspond to, face to, or overlap with the magnet 130 in the second direction. Furthermore, for example, the magnetic body 82 may be disposed so as to correspond to, face to, or overlap with the coil 120 in the second direction. For example, the magnetic body 82 may be disposed on a first extension portion 802A of the second substrate 802. For example, the coil 120 may be disposed on a first surface of the first extension portion 802A facing the magnet 130, and the magnetic body 82 may be disposed on a second surface of the first extension portion 802A opposite the first surface of the first extension portion 802A. The magnetic body 82 may be bonded, attached, or fixed to the first extension portion 802A by an adhesive.

[0255] 10a and 10b, the housing 210 may include a cavity for accommodating the OIS operating portion. For example, the housing 210 may have a shape corresponding to the OIS operating portion, such as the holder 140 or the sensor base 270, such as, but not limited to, a polygonal (e.g., rectangular or octagonal) or circular (or elliptical) shape. The housing 210 may also be referred to as a "base."

[0256] 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 corners located between two adjacent sides.

[0257] The housing 210 may also include a lower portion (or lower plate) 42 located below the sides 71A to 71D. The lower portion 42 may be connected to the undersides of the sides 71A to 71D. For example, the lower portion 42 may be interchangeably referred to as a "bottom," "bottom surface," or "body." For example, the sides 71A to 71D may protrude upward from the lower portion 42.

[0258] The housing 210 may include a first side 71A corresponding to, facing, or overlapping with the first side 41A of the holder 140, a second side 71B corresponding to, facing, or overlapping with the second side 41B of the holder 140, a third side 71C corresponding to, facing, or overlapping with the third side 41C of the holder 140, and a fourth side 71D corresponding to, facing, or overlapping with the fourth side 41D of the holder 140.

[0259] The first side 71A (or first side surface or first outer surface) of the housing 210 may be located opposite the second side 71B (or second side surface or second outer surface) of the housing 210, and the third side 71C (or third side surface or third outer surface) of the housing 210 may be located opposite the fourth side 71D (or fourth side surface or fourth outer surface) of the housing 210.

[0260] For example, each of the first to fourth sides 71A to 71D of the housing 210 may be disposed parallel to a corresponding one of the side plates 302 of the cover member 300.

[0261] The housing 210 may include a step 411 disposed on a lower portion of any one of the side portions 71A to 71D. For example, the step 411 may protrude from the outer surface of the side portions 71A to 71D of the housing 210 in a direction perpendicular to the optical axis. For example, the step 411 may face or overlap the side plate 302 of the cover member 300 in the optical axis direction. For example, the step 411 may be bonded to the side plate 302 of the cover member 300 with an adhesive.

[0262] The housing 210 may include seats 141A and 141B for accommodating the magnet 310. For example, the seats 141A and 141B may have groove shapes formed on the sides of the housing 210. In another embodiment, the seats 141A and 141B may be through-holes formed on the sides of the housing 210.

[0263] The housing 210 may include a first seat 141A for disposing the first magnet unit 310A and a second seat 141B for disposing the second magnet unit 310B. For example, the first seat 141A may be disposed on or formed on the second side 71B of the housing 210, and the second seat 141B may be disposed on or formed on the third side 71C of the housing 210. For example, the first seat 141A may be disposed on or formed on the inner surface of the second side 71B of the housing 210, and the second seat 141B may be disposed on or formed on the inner surface of the third side 71C of the housing 210.

[0264] The magnet 310 may include a first magnet unit 310A disposed on the second side 71B of the housing 210 and a second magnet unit 310B disposed on the third side 71C of the housing 210.

[0265] For example, the first magnet unit 310A and the second magnet unit 310B may be arranged offset in the second direction or the third direction. For example, the first magnet unit 310A and the second magnet unit 310B may be arranged in the housing 210 so as not to overlap each other in the second direction or the third direction. For example, the first magnet unit 310A and the second magnet unit 310B may be arranged on two different sides of the housing 210 so as not to overlap each other in the second direction or the third direction.

[0266] In another embodiment, the magnet 310 may be disposed in the holder 140, and the coil 230 may be disposed in the housing 210. For example, the magnet 310 and the coil 230 may be disposed so that their positions are opposite to each other in FIG. 3. Here, the camera device 200 may include a separate current-carrying part, such as a circuit board, a circuit member, or a conductive member, that electrically connects the second coil 230 and the circuit board 800.

[0267] Each of the first magnet unit 310A and the second magnet unit 310B may be a two-pole magnet including one north pole and one south pole. For example, the first magnet unit 310A and the second magnet unit 310B may be a two-pole magnet divided into or arranged with north and south poles in the optical axis direction. For example, the north pole (or south pole) of each of the first magnet unit 310A and the second magnet unit 310B may be located above the south pole (or north pole).

[0268] In another embodiment, each of the first magnet unit 310A and the second magnet unit 310B may be a two-pole magnet divided or arranged into north and south poles in a direction perpendicular to the optical axis direction. In yet another embodiment, each of the first magnet unit 310A and the second magnet unit 310B may be a four-pole magnet including two north poles and two south poles.

[0269] The housing 210 may include a receiving portion 49A for receiving the magnetic substance 32. The receiving portion 49A may be disposed in or formed in the lower portion 42 of the housing 210. The receiving portion 49A may be disposed in or formed on an upper surface of the lower portion 42 of the housing 210. For example, the receiving portion 49A may be a groove recessed from the upper surface of the lower portion 42 of the housing 210. The receiving portion 49A may have a shape corresponding to the magnetic substance 32, such as a square or circle. For example, the receiving portion 49A of the housing 210 may correspond to, face, or overlap with the receiving portion 28A of the sensor base 270 in the optical axis direction.

[0270] Although not shown in FIG. 10 a , the housing 210 may also include a groove in which at least another portion of the moving plate 60 is disposed or for receiving at least another portion of the moving plate 60 .

[0271] The housing 210 may include grooves 55 in which the rolling members 63 are disposed or for accommodating the rolling members 63. The grooves 55 may be formed in the upper surface of the lower portion 42 of the housing 210. For example, the grooves 55 may be recessed from the upper surface of the lower portion 42 of the housing 210. The number of grooves 55 in the housing 210 may be the same as the number of the rolling members 63.

[0272] For example, the groove 55 may include two grooves 55A and 55B spaced apart from each other. For example, the two grooves 55A and 55B may be spaced apart from each other in the Y-axis direction. For example, the direction in which the two grooves 55A and 55B of the housing 210 are spaced apart from each other may be perpendicular to the direction in which the two grooves 29A and 29B of the sensor base 270 are spaced apart from each other. For example, the receiving portion 49A may be located between the two grooves 55A and 55B of the housing 210.

[0273] The groove 55 of the housing 210 may contact the rolling member 63 at at least one point. For example, the groove 55 may include a bottom surface and at least one side surface connected to the bottom surface. At least one side surface of the groove 55 may be an inclined surface. For example, the groove 55 may include a bottom surface and multiple inclined surfaces. The shapes of the inclined surfaces of the groove 55 may be the same as each other. In other embodiments, at least one of the inclined surfaces of the groove 55 may have a different shape from the rest.

[0274] The housing 210 may include a protrusion 215 that protrudes in a direction perpendicular to the optical axis. For example, the protrusion 215 may protrude from a side of the housing 210.

[0275] For example, the protrusion 215 may protrude from the outer surface of the fourth side portion 71D of the housing 210. For example, the protrusion 215 may have a form in which at least a portion of the fourth side portion 71D protrudes in a direction parallel to a line that passes through the optical axis and is perpendicular to the optical axis. For example, the protrusion 215 may include a groove (or cavity) 16A in which at least a portion of the fourth substrate 804 is disposed or accommodated. For example, the groove 16A of the protrusion 215 may include an opening that opens upward.

[0276] 10a, coupling grooves 215A and 215B for inserting, coupling, or fixing the movement suppressing portion 80 may be formed in the groove 16A of the protrusion 215. For example, the coupling grooves 215A and 215B may be formed on two inner surfaces of the groove 16A of the protrusion 215 that face each other. For example, the coupling grooves 215A and 215B may extend in the optical axis direction. For example, the coupling grooves 215A and 215B may include openings that open on the upper surface of the protrusion 215 to easily insert or couple the movement suppressing portion 80 from above.

[0277] The maximum length of the protrusion 215 in the optical axis direction may be smaller than the maximum length of the housing 210 in the optical axis direction. With this configuration, it is possible to easily secure a space for the circuit board 800 to extend outward, thereby realizing a compact camera device.

[0278] Camera device 200 may include a movement suppressing portion 80 coupled to at least a portion of housing 210. Movement suppressing portion 80 suppresses movement or movement of at least a portion of fourth substrate 804, and can suppress deformation of the shape of at least a portion of fourth substrate 804.

[0279] 7c, 8, and 11, the fourth substrate 804 of the circuit board 800 may include a first portion (or "first region") 804A connected to the first substrate 801, a second portion 804B connected to the first portion 804A and bent from the first portion 804A, and a third portion 804C connected to the second portion 804B and bent from the second portion 804B. In other embodiments, one of the first portion 804A and the second portion 804B may be omitted.

[0280] For example, the first portion 804A may extend in a direction parallel to the first substrate 801. For example, the second portion 804B may be bent from the first portion 804A and extend upward from the first portion 804A. For example, the third portion 804C may extend from the second portion 804B in a direction opposite to the first portion 804A.

[0281] For example, the fourth substrate 804 may include a first bent portion 804D connecting the first portion 804A and the second portion 804B. The fourth substrate 804 may also include a second bent portion 804E connecting the second portion 804B and the third portion 804C. The first bent portion 804D and the second bent portion 804E may be angled relative to each other, or, for example, the first portion 804A and the second portion 804B may be perpendicular to each other. In other embodiments, the first bent portion 804D and the second bent portion 804E may have a rounded shape. In other embodiments, the interior angle between the first portion 804A and the second portion 804B may be an acute angle or an obtuse angle.

[0282] The first bent portion 804D and the second bent portion 804E can prevent an increase in the length in a direction perpendicular to the optical axis direction of the camera device 200. Furthermore, since the first bent portion 804D and the second bent portion 804E are located 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), an increase in the length of the camera device 200 in the optical axis direction can be prevented, and the camera device can be made more compact.

[0283] For example, the third portion 804C may have the shape of a plate or a plane perpendicular to the optical axis. For example, the third portion 804C may have a serpentine or wave shape. For example, the third portion 804C may include at least one folded 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-shape or a V-shape.

[0284] For example, third portion 804C can be spaced apart from housing 210. For example, third portion 804C can be spaced apart from protrusion 215 of housing 210. In other embodiments, for example, at least a portion of third portion 804C can contact protrusion 215 of housing 210.

[0285] 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 be disposed within the groove 16A of the protrusion 215. The third portion 804C of the fourth substrate 804 may be located outside the protrusion 215 of the housing 210. For example, the third portion 804C of the fourth substrate 804 may be located above the protrusion 215 of the housing 210. A lower surface of the third portion 804C of the fourth substrate 804 may be located above an upper surface of the protrusion 215 of the housing 210.

[0286] The connector 805 may be coupled or connected to another connector outside the camera device 200 or an external device. The connector 805, which is coupled to another external connector, may correspond to a fixed part that does not move when the OIS is operated. The third part 804C of the fourth substrate 804 includes at least one bent or curved region, and thus can elastically support the camera device 200 or the OIS operating part and can serve to absorb external shocks. That is, the third part 804C of the fourth substrate 804 can serve as a spring that absorbs shocks. Furthermore, because the third part 804C of the fourth substrate 804 can serve to elastically support the OIS operating part, the driving force or driving power required when the OIS is operated can be reduced.

[0287] Camera apparatus 200 may include a reinforcing member 70 disposed on, coupled to, or attached to at least a portion of fourth substrate 804. Reinforcing member 70 may be disposed on, coupled to, or attached to any one of first portion 804A and second portion 804B of fourth substrate 804. For example, reinforcing member 70 may be disposed on, coupled to, or attached to at least a portion of first portion 804A and at least a portion of second portion 804B of fourth substrate 804.

[0288] 11 , for example, the reinforcing member 70 may be disposed on, coupled to, or attached to the lower surface of the first portion 804A and the lower surface of the second portion 804B of the fourth substrate 804. For example, the reinforcing member 70 may include a first region 70A disposed on, coupled to, or attached to the first portion 804A, and a second region 70B disposed on, coupled to, or attached to the second portion 804B. The second region 70B may be bent upward from the first region 70A. For example, a bent portion may be formed between the first region 70A and the second region 70B.

[0289] 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.

[0290] For example, the reinforcing member 70 can be spaced apart from the third portion 804C of the fourth substrate 804. For example, the second region 70B of the reinforcing member 70 can be spaced apart from the third portion 804C of the fourth substrate 804. In other embodiments, at least a portion of the second region 70B of the reinforcing member 70 can contact the third portion 804C of the fourth substrate 804.

[0291] In other embodiments, the reinforcing member 70 may be disposed on, coupled to, or attached to an upper surface of the first portion 804A and an upper surface of the second portion 804B of the fourth substrate 804. For example, in other embodiments, the reinforcing member 70 may include a first region disposed on the upper surface of the first portion 804A of the fourth substrate 804 and a second region disposed on the upper surface of the second portion 804B.

[0292] In yet another embodiment, the reinforcing member 70 may be disposed on, coupled to, 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. For example, in another embodiment, the reinforcing member 70 may be disposed on, coupled to, or attached to the second portion 804B and the third portion 804C of the fourth substrate 804. For example, the reinforcing member 70 may include a first region disposed on, coupled to, or attached to the second portion 804B of the fourth substrate 804 and a second region disposed on, coupled to, or attached to the third portion 804C, and a bent portion may be formed between the first and second regions. The first region of the reinforcing member 70 may be disposed on the lower surface (or upper surface) of the second portion 804B, and the second region of the reinforcing member 70 may be disposed on the lower surface (or upper surface) of the third portion 804C.

[0293] The reinforcing member 70 can prevent the fourth substrate 804 from being damaged, deformed, or broken due to an impact or an external force. In addition, the reinforcing member 70 can prevent a force from being applied to the fourth substrate 804 due to tilting of the OIS operating unit 100, or prevent the fourth substrate 804 from being deformed and restored to its original shape. For example, the reinforcing member 70 can include at least one of a metal material and an injection molding material.

[0294] For example, the reinforcing member 70 may be disposed within the groove 16A of the protrusion 215 of the housing 210. For example, the reinforcing member 70 may be in at least partial contact with the groove 16A of the protrusion 215 of the housing 210. For example, the reinforcing member 70 may not be bonded to the housing 210 (e.g., the protrusion 215). In other embodiments, for example, the reinforcing member 70 may be bonded to the housing 210 (e.g., the protrusion 215) by an adhesive.

[0295] 1, 10a, and 10b, the movement suppressing portion 80 may be coupled to the protrusion 215 of the housing 210. For example, the movement suppressing portion 80 may be coupled to the coupling grooves 215A and 215B of the protrusion 215 of the housing 210.

[0296] 3 , at least a portion of second portion 804B of fourth substrate 804 may be disposed between movement suppressing portion 80 and the inner surface of protrusion 215 of housing 210. For example, at least a portion of reinforcing member 70 may be disposed between movement suppressing portion 80 and the inner surface of protrusion 215 of housing 210.

[0297] The movement suppressing portion 80 may 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 suppressing portion 80 may be spaced apart from the circuit board 800 in the optical axis direction or in a direction perpendicular to the optical axis direction. That is, the movement suppressing portion 80 may serve to maintain the shape of the bent portions 804D and 804E of the fourth substrate 804, which is a flexible substrate. For example, the movement suppressing portion 80 may be an injection-molded product made of a non-magnetic material or resin. In another embodiment, the movement suppressing portion 80 may contact at least a portion of the fourth substrate 804 of the circuit board 800.

[0298] The movement suppressing unit 80 can restrict the movement or operation of at least a part of the second portion 804B of the fourth substrate 804 arranged in the groove 16A of the protrusion 215, and can suppress or prevent the second portion 804B from coming out of the groove 16A of the protrusion 215. Therefore, when the OIS is driven, the OIS operating unit can be suppressed or prevented from being affected by the restoring force of the fourth substrate 804, allowing for accurate OIS driving and improving the reliability of OIS driving. The movement suppressing unit 80 can also be expressed as a "clamp."

[0299] The cover member 300 may form an accommodation space together with the housing 210, and an OIS operating unit may be disposed in the accommodation space. For example, the cover member 300 may have a box shape with an open bottom. For example, the cover member 300 may include an upper plate 301 and a side plate 302 connected to the upper plate 301.

[0300] The lower end of the side plate 302 of the cover member 300 may be coupled to the housing 210. The shape of the top plate 301 of the cover member 300 may be polygonal (e.g., rectangular or octagonal) or circular. The top plate 301 of the cover member 300 may include an opening 303 for exposing a lens (not shown) to external light. The opening 303 may be a through-hole formed in the top plate 301 of the cover member 300 in the optical axis direction. For example, the side plate of the cover member 300 may include a plurality of side plates. The material of the cover member 300 may be a non-magnetic material. In another embodiment, the cover member 300 may be a magnetic material. For example, the material of the cover member 300 may be an injection-molded product such as resin, or a metal material.

[0301] 1 and 2a, the cover member 300 may include an opening 304 disposed or formed in the side plate 302 to avoid spatial interference with the protrusion 215 of the housing 210. For example, the protrusion 215 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.

[0302] The cover member 300 is disposed over the opening 304 and may include a protrusion 305 protruding from the side plate 302. The protrusion 305 may have a plate shape. For example, the protrusion 305 of the cover member 300 may be disposed over 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 suppressing portion 80. For example, the protrusion 305 may overlap the movement suppressing portion 80 in the optical axis direction. Furthermore, for example, the protrusion 305 may overlap a first portion 804A of the fourth substrate 804 in the optical axis direction. The protrusion 305 can suppress or prevent the movement suppressing portion 80 from coming off and can protect the movement suppressing portion 80 and the fourth substrate 804 from impact.

[0303] 4e, the cover member 300 may include a protrusion 311 protruding from the upper plate 301. For example, the protrusion 311 may protrude from the inner surface of the upper plate 301 of the cover member 300 toward the bobbin 110 or the rolling member 21. For example, the protrusion 311 may face or overlap the accommodating portion 116 of the bobbin 110 in the optical axis direction. At least a portion of the protrusion 311 may be inserted or disposed within the accommodating portion 116 of the bobbin 110. The protrusion 311 may be disposed on the rolling member 21.

[0304] For example, the cover member 300 may include a first protrusion 311A ​​corresponding to, facing, or overlapping with the first rolling member 21A or the first receiving portion 116A of the bobbin 110. For example, the cover member 300 may include a second protrusion 311B corresponding to, facing, or overlapping with the second rolling member 21B or the second receiving portion 116B of the bobbin 110. For example, the protrusion 311 may include a groove recessed from the upper surface of the upper plate 301 of the cover member 330. In other embodiments, the protrusion 311 may not include a groove.

[0305] The cover member 300 has the protrusion 311, so that in this embodiment, the rolling member 21 can be prevented from coming off the receiving portion 116 of the bobbin 110. The protrusion 311 can also function as a stopper that prevents the bobbin 110 from moving further upward within a limited range.

[0306] Next, the support portion will be described.

[0307] The support portion is disposed between the sensor base 270 and the housing 210 and can support the sensor base 270 relative to the housing 210. The support portion may include a moving plate 60 disposed between the sensor base 270 and the housing 210. The support portion may also include a rolling member 62 disposed between the moving plate 60 and the sensor base 270. The support portion may also include a rolling member 63 disposed between the moving plate 60 and the housing 210.

[0308] Moving plate 60 may also be referred to interchangeably as a "drive plate," "mover," "mover plate," "drive plate," "plate," "rotating plate," "tilting plate," "moving plate," or "support plate."

[0309] The moving plate 60 can be tilted about the first or second axis or rotated by a preset angle.

[0310] For example, moving plate 60 may be disposed between the lower portion (or lower surface) of sensor base 270 and lower portion 42 of housing 210. For example, at least a portion of moving plate 60 may be disposed within seat 25A of sensor base 270. Because moving plate 60 is disposed within seat 25A, the length or height of camera device 200 in the optical axis direction can be reduced.

[0311] 4b, 9a, and 12, the moving plate 60 may have a plate shape. For example, the length of the moving plate 60 in the horizontal direction perpendicular to the optical axis (e.g., the lateral or vertical direction) may be greater than the length of the moving plate 60 in the optical axis direction.

[0312] 9a, the moving plate 60 may include a groove 65 in which at least a portion of the rolling member 62 is disposed. The groove 65 may be disposed or formed on a first surface 6A of the moving plate 60. The first surface 6A may be a surface that faces or opposes the holder 260. The groove 65 may be recessed from the first surface 6A of the moving plate 60.

[0313] For example, the moving plate 60 may include a first groove 65A for disposing at least a portion of the first ball member 62A and a second groove 65B for disposing at least a portion of the second ball member 62B. For example, the grooves 65A and 65B may be disposed apart from each other in the second direction (e.g., the X-axis direction). For example, the ball members 62A and 62B may be disposed apart from each other in the second direction (e.g., the X-axis direction).

[0314] In another embodiment, the grooves of the moving plate 60 for arranging the ball members 62A and 62B may be spaced apart in a third direction (e.g., the Y-axis direction). That is, in another embodiment, the ball members of the rolling members 62 may be spaced apart in the third direction.

[0315] The groove 65 may contact the rolling member 62 at at least one point. For example, the groove 65 may include a bottom surface and at least one side surface connected to the bottom surface. At least one side surface of the groove 65 may be an inclined surface. For example, the groove 65 may include a bottom surface and multiple inclined surfaces. The shapes of the inclined surfaces of the groove 65 may be the same as each other. In other embodiments, at least one of the inclined surfaces of the groove 65 may have a different shape from the rest.

[0316] 9b, the moving plate 60 may include a groove 66 in which at least a portion of the rolling member 63 is disposed. The groove 66 may be disposed or formed on the second surface 6B of the moving plate 60. The second surface 6B may be the surface facing or opposing the housing 210. The second surface 6B may also be the surface opposite the first surface 6A of the moving plate 60. The groove 66 may be recessed from the second surface 6B of the moving plate 60.

[0317] For example, the moving plate 60 may include a first groove 66A for disposing at least a portion of the first ball member 63A and a second groove 66B for disposing at least a portion of the second ball member 63B. For example, the grooves 66A and 66B may be disposed apart from each other in a third direction (e.g., the Y-axis direction). For example, the ball members 63A and 63B may be disposed apart from each other in the third direction (e.g., the Y-axis direction).

[0318] In another embodiment, the grooves of the moving plate 60 for arranging the ball members 63A and 63B may be spaced apart in the second direction (e.g., the X-axis direction). That is, in another embodiment, the ball members of the rolling members 63 may be spaced apart in the second direction.

[0319] The groove 66 may contact the rolling member 63 at at least one point. For example, the groove 66 may include a bottom surface and at least one side surface connected to the bottom surface. At least one side surface of the groove 66 may be an inclined surface. For example, the groove 66 may include a bottom surface and multiple inclined surfaces. The inclined surfaces of the groove 66 may have the same shape. In other embodiments, at least one of the inclined surfaces of the groove 66 may have a different shape from the rest.

[0320] The moving plate 60 may include a first escape portion 61A to avoid spatial interference with the gyro sensor 820. The moving plate 60 may also include a second escape portion 61B provided at a position corresponding to or symmetrical to the first escape portion 61A. The second escape portion 61B maintains a weight balance with respect to the first escape portion 61A, allowing the moving plate 60 to tilt or rotate balanced, thereby improving the reliability of the OIS operation.

[0321] For example, the first recess 61A may be a groove recessed from one region of the outer surface of the moving plate 60. The second recess 61B may be a groove recessed from another region of the outer surface of the moving plate 60. For example, the moving plate 60 may include four corners (or corner regions), where the first recess 61A may be formed in a first corner of the moving plate 60 and the second recess 61B may be formed in a second corner opposite the first corner. The third and fourth corners of the moving plate 60 may be rounded, but in other embodiments, at least one of the first to fourth corners may be formed in a right-angled shape.

[0322] The moving plate 60 may include an opening 60A that corresponds to, faces, or overlaps with the magnet 31 and / or magnetic material 32. For example, the opening 60A may correspond to, face, or overlap with the protrusion 28 of the sensor base 270. The opening 60A can reduce the weight (or mass) of the moving plate 60, thereby making the camera device 200 lighter.

[0323] For example, the opening 60A of the moving plate 60 may be disposed at a position corresponding to the protrusion 28 of the sensor base 270 to avoid spatial interference with the protrusion 28. The opening 60A may also be formed to avoid spatial interference with the magnet 31 and the protrusion 28 of the sensor base 270.

[0324] For example, the opening 60A of the moving plate 60 may be a through-hole. For example, the opening 60A may penetrate the moving plate 60 in the first direction (Z-axis direction) or the optical axis direction. For example, at least a portion of the opening 60A of the moving plate 60 may include a shape corresponding to the protrusion 28 of the sensor base 270. For example, the opening 60A may have a circular, elliptical, or polygonal shape, such as a square.

[0325] For example, the horizontal length of the opening 60A may be greater than the horizontal length of the protrusion 28 of the sensor base 270. In other embodiments, the horizontal length of the opening 60A may be the same as the horizontal length of the protrusion 28 of the sensor base 270. The vertical length of the opening 60A may be greater than the vertical length of the protrusion 28 of the sensor base 270. In other embodiments, the vertical length of the opening 60A may be the same as the vertical length of the protrusion 28 of the sensor base 270.

[0326] At least a portion of the protrusion 28 of the sensor base 270 may be disposed within the opening 60A of the moving plate 60. For example, the protrusion 28 of the sensor base 270 may overlap with the opening 60A of the moving plate 60 in the optical axis direction. Also, for example, the protrusion 28 of the sensor base 270 may overlap with the moving plate 60 in a direction perpendicular to the optical axis direction. Thus, the length or height of the camera device 200 in the optical axis direction can be reduced.

[0327] For example, the opening 60A can be disposed between the grooves 65A and 65B of the moving plate 60. Also, the opening 60A can be disposed between the grooves 66A and 66B of the moving plate 60.

[0328] For example, the moving plate 60 may be an injection molded product. For example, the moving plate 60 may be made of a plastic, resin, or ceramic material. In other embodiments, the moving plate 60 may include a metal material, such as stainless steel. The moving plate 60 may also be a non-magnetic material. In other embodiments, the moving plate 60 may be a magnetic material.

[0329] The rolling members 62 and 63 may be arranged parallel to each other or perpendicular to each other. The rolling member 62 allows the OIS operating unit to rotate, pivot, or tilt in either the second direction or the third direction. The rolling member 63 allows the OIS operating unit to rotate, pivot, or tilt in the other of the second direction and the third direction.

[0330] The rolling member 62 may be disposed between the sensor base 270 and the moving plate 60. The rolling member 62 may include one or more ball members. In Fig. 2a, the rolling member 62 includes two ball members, but in other embodiments, the rolling member 62 may include three or more ball members.

[0331] For example, the rolling member 62 may be disposed between the lower portion (or lower surface) of the sensor base 270 and the first surface 6A of the moving plate 60. For example, the rolling member 62 may be disposed between the groove 29 of the sensor base 270 and the groove 65 of the moving plate 60. In order to reduce frictional force, a lubricant may be disposed in either the groove 29 of the sensor base 270 or the groove 65 of the moving plate 60.

[0332] The rolling member 63 may be disposed between the moving plate 60 and the housing 210 .

[0333] The rolling member 63 may include one or more ball members. In Figure 2a, the rolling member 63 includes two ball members, but in other embodiments, the rolling member 63 may include three or more ball members.

[0334] For example, the rolling member 63 may be disposed between the second surface 6B of the moving plate 60 and the lower portion 42 of the housing 210. For example, the rolling member 63 may be disposed between the groove 66 of the moving plate 60 and the groove 55 of the housing 210. In order to reduce frictional force, a lubricant may be disposed in either the groove 66 of the moving plate 60 or the groove 55 of the housing 210.

[0335] The rolling members 62, 63 may be rolling members. For example, the rolling members 62, 63 may be "balls," "ball members," or "ball bearings." Although the number of each of the rolling members 62, 63 is two in this example, in other embodiments, the number may be one or three or more. Because the rolling members 62, 63 perform rolling or sliding motion, the relative frictional force can be reduced, thereby reducing the current or power consumption for driving the OIS.

[0336] 4d, the rolling members 21 may not overlap with the moving plate 60 in the optical axis direction. For example, as shown in FIG. 4c, the rolling members 21 may not overlap with the moving plate 60 in the direction perpendicular to the optical axis.

[0337] For example, the direction of separation between the first rolling member 21A and the second rolling member 21B may be perpendicular to the direction of separation between the ball members 62A and 62B or may intersect each other. In other embodiments, the former and the latter may be parallel.

[0338] For example, the direction of separation between the first rolling member 21A and the second rolling member 21B may be parallel to or intersect with the direction of separation between the ball members 63A and 63B. In other embodiments, the former and the latter may be perpendicular.

[0339] For example, when viewed from above, the separation distance between ball member 63A and ball member 63B may be smaller than the separation distance between first rolling member 21A and second rolling member 21B. In other embodiments, the separation distance between ball member 63A and ball member 63B may be the same as or larger than the separation distance between first rolling member 21A and second rolling member 21B.

[0340] For example, when viewed from above, the separation distance between ball member 62A and ball member 62B may be smaller than the separation distance between first rolling member 21A and second rolling member 21B. In other embodiments, the separation distance between ball member 62A and ball member 62B may be the same as or larger than the separation distance between first rolling member 21A and second rolling member 21B.

[0341] The support portion may include a magnet 31 disposed in the OIS operating portion (e.g., sensor base 270) and a magnetic body 32 disposed in the fixed portion (e.g., housing 210). In another embodiment, the magnet 31 may be disposed in the fixed portion (e.g., housing 210), and the magnetic body 32 may be disposed in the OIS operating portion (e.g., sensor base 270). The magnet 31 may also be referred to as a "magnetic body," a "yoke," or a "holding magnet."

[0342] For example, the magnet 31 can be disposed in or coupled to the groove 28A of the protrusion 28 of the sensor base 270. At least a portion of the magnet 31 can be disposed in the opening 60A of the moving plate 60. For example, the magnet 31 can face or overlap the opening 60A of the moving plate 60 in the optical axis direction. For example, the magnet 31 does not have to overlap with the moving plate 60 in the optical axis direction. Also, for example, at least a portion of the magnet 31 can overlap with the moving plate 60 in a direction perpendicular to the optical axis.

[0343] The magnet 31 may correspond to, face, or overlap with the magnetic body 32 in the optical axis direction. The magnet 31 may be a two-pole magnet divided into a north pole and a south pole. For example, the magnet 31 may be a two-pole magnet divided or arranged into a north pole and a south pole in the optical axis direction. In another embodiment, the magnet 31 may be a two-pole magnet divided or arranged into a north pole and a south pole in a direction perpendicular to the optical axis direction. In yet another embodiment, the magnet 31 may be a four-pole magnet including two north poles and two south poles.

[0344] The magnetic body 32 may be disposed below the magnet 31. The magnetic body 32 may be disposed in the groove 46 of the housing 210. For example, the magnetic body 32 may be coupled with the groove 46 of the housing 210.

[0345] The magnetic body 32 may overlap the opening 60A of the moving plate 60 in the optical axis direction. The magnetic body 32 does not have to overlap the moving plate 60 in the optical axis direction. The magnetic body 32 does not have to overlap the moving plate 60 in the direction perpendicular to the optical axis. In other embodiments, the magnetic body 32 can overlap the moving plate 60 in the direction perpendicular to the optical axis.

[0346] When viewed from above, the area of ​​opening 60A of moving plate 60 may be larger than the area of ​​the upper surface (or lower surface) of magnet 31. Also, when viewed from above, the area of ​​opening 60A of moving plate 60 may be larger than the area of ​​the upper surface (or lower surface) of magnetic body 32.

[0347] For example, an attractive force may act between the magnetic body 32 and the magnet 31 in the optical axis direction (or the first direction). The magnetic body 32 may be made of a material that is attracted to the magnet 31. For example, the magnetic body 32 may be made of a metal material that is attracted to a magnet. Alternatively, for example, the magnetic body 32 may be made of a metal material that has magnetism. Alternatively, for example, the magnetic body 32 may be a magnet. The magnetic body 32 may also be expressed as a "yoke."

[0348] The attractive force between the magnetic body 32 and the magnet 31 allows the sensor base 270 and the housing 210 to press the moving plate 60, and the moving plate 60 and the rolling members 62, 63 to be in close contact with the sensor base 270 and / or the housing 210. The attractive force between the magnetic body 32 and the magnet 31 allows the moving plate 60 and the rolling members 62, 63 to stably support the OIS operating part relative to the fixed part, allowing stable OIS operation to be performed.

[0349] Furthermore, since at least a portion of the magnet 31 is positioned within the opening 60A of the moving plate 60, the separation distance between the magnet 31 and the magnetic body 32 can be reduced, thereby increasing the attractive force between the magnet 31 and the magnetic body 32, and enabling the OIS operating part to be stably supported on the fixed part.

[0350] Furthermore, since the magnet 31 is disposed in the central region of the underside of the sensor base 270 and the magnetic body 32 is disposed in the center of the lower part 42 of the housing 210, the attractive force between the magnet 31 and the magnetic body 32 can be concentrated in the center of the sensor base 270 and the center of the housing 210, thereby enabling efficient and stable support of the OIS operating part.

[0351] In another embodiment, the protrusion of the sensor base 270 may be omitted, the magnet 31 may be disposed on the lower surface of the sensor base 270, the housing 210 may include a protrusion disposed on the lower portion 42 of the housing 210 to correspond to, face, or overlap with the opening 60A of the moving plate 60, and the magnetic member 32 may be disposed on the protrusion of the housing 210. Here, the seat 25A of the sensor base 270 may be omitted, and a seat corresponding to or identical to the seat 25A of the sensor base 270 may be formed on the upper surface of the lower portion 42 of the housing 210, the moving plate 60 may be disposed within the seat of the housing 210, the protrusion may protrude from the bottom surface of the seat of the housing 210, a groove in which the magnetic member 32 is disposed may be formed in the protrusion of the housing 210, and a groove in which the magnet 31 is disposed may be formed in the lower surface of the sensor base 270. In yet another embodiment, at least a portion of the protrusion of the housing 210 may be disposed within the opening 60A of the moving plate 60 and overlap with the moving plate 60 in a direction perpendicular to the optical axis. In yet another embodiment, a magnet 31 may be disposed in the protrusion (or the groove of the protrusion) of the housing 210, and a magnetic body 32 may be disposed in the sensor base 270 (or the groove of the sensor base 270).

[0352] In another embodiment, the rolling members 62 and 63 may be omitted, and the moving plate may include first protrusions disposed or formed at the positions of the grooves 65A and 65B, and second protrusions disposed or formed at the positions of the grooves 66A and 66B. Here, the first protrusions may protrude from the first surface 6A of the moving plate 60, and the second protrusions may protrude from the second surface 6B of the moving plate 60. For example, each of the first protrusions may have a hemispherical or dome shape, and each of the second protrusions may have a hemispherical, semicircular, semi-elliptical, or dome shape. That is, in another embodiment, the rolling members may be integral with the moving plate.

[0353] In yet another embodiment, the moving plate 60 may be omitted, and the support unit may include rolling members, for example, ball members, disposed between the sensor base 270 and the housing 210. Here, the rolling members may include two first ball members disposed in a direction parallel to one axis and two second ball members disposed in a direction parallel to a second axis, and the OIS operating unit may tilt around the first ball members as an axis or rotate by a predetermined angle, and may tilt around the second ball members as an axis or rotate by a predetermined angle, thereby performing an image stabilization operation.

[0354] FIG. 13a is a diagram illustrating the electromagnetic forces F1 and F2 caused by the interaction between the magnet units 310A and 310B and the coil units 230A and 230B and the operation of the moving plate 60, and FIG. 13b shows the operation of the OIS operating unit 100 caused by the electromagnetic forces of FIG. 13a.

[0355] 13a and 13b, the operation of the OIS operating unit by the OIS driving unit will be described. The OIS driving unit may include a coil 230 and a magnet 310. The OIS driving unit may also include a position sensor 240.

[0356] 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 act in the optical axis direction, for example, in the upward or downward direction.

[0357] The first electromagnetic force F1 can tilt the OIS operating unit around a second axis (e.g., the Y-axis) (or the ball member 63). For example, the first electromagnetic force F1 can tilt the OIS operating unit around the second axis. Here, the second-axis (Y-axis) tilting can mean that the OIS operating unit tilts around the second axis (Y-axis) or that the OIS operating unit rotates left or right by a preset angle around the second axis (Y-axis) as the rotation axis.

[0358] For example, the first electromagnetic force F1 can tilt the moving plate 60 about a second axis (e.g., the Y axis) (or the ball member 63). For example, the first electromagnetic force F1 can tilt the moving plate 60 about the second axis.

[0359] 4b, in order for the OIS operating unit to tilt based on the second axis (or ball member 63), a gap or space may be formed between the moving plate 60 and the OIS operating unit (e.g., sensor base 270) by the first ball members 62A and 62B. For example, a gap or space allowing the moving plate 60 to move may be formed between the upper surface 6A of the moving plate 60 and the OIS operating unit (e.g., sensor base 270). For example, the upper surface 6A of the moving plate 60 may be spaced apart from the OIS operating unit (e.g., sensor base 270) or the lower surface of the sensor base 270.

[0360] 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 act in an upward or downward direction.

[0361] The second electromagnetic force F2 can tilt the OIS operating unit around a first axis (e.g., the X-axis) (or ball member 62). For example, the second electromagnetic force F2 can tilt the OIS operating unit around the first axis. Here, first-axis (X-axis) tilting can mean that the OIS operating unit tilts around the first axis (X-axis) or that the OIS operating unit rotates left or right by a preset angle around the first axis (X-axis) as the rotation axis.

[0362] For example, the second electromagnetic force F2 can tilt the moving plate 60 about a first axis (e.g., the X-axis) (or the ball member 62). For example, the second electromagnetic force F2 can tilt the moving plate 60 about the first axis.

[0363] Referring to FIG. 4a, in order for the OIS operating unit to tilt based on the first axis (or ball member 62), there may be a gap or space between the moving plate 60 and the moving unit (e.g., sensor base 270) due to the ball member 62.

[0364] For example, there may be a space or gap between the upper surface 6A of the moving plate 60 and the moving part (e.g., sensor base 270) that allows the moving plate 60 to move. For example, the upper surface 6A of the moving plate 60 may be spaced apart from the moving part (e.g., sensor base 270) or the lower surface of the sensor base 270.

[0365] For example, the first axis or second axis tilting may cause the moving plate 60 to come into contact with a moving part (e.g., the sensor base 270) or a fixed part (e.g., the housing 210). Here, the fixed part or the moving part may act as a stopper that suppresses the tilting of the OIS operating part.

[0366] In a camera device (hereinafter referred to as "Comparative Example 1") in which the image sensor is fixed and the lens moves in a direction perpendicular to the optical axis for image stabilization or shake correction, image distortion may occur. Furthermore, in a camera device (hereinafter referred to as "Comparative Example 2") in which the lens is fixed and not moved but the image sensor is moved or tilted for image stabilization, image distortion may occur at the edges or corners of the image sensor. In Comparative Examples 1 and 2, the image sensor and lens are separated, and only one of the image sensor and lens moves or tilts, so image distortion may occur during image stabilization, making it difficult to achieve wide-angle image stabilization.

[0367] In this embodiment, for image stabilization, the OIS driver may tilt the OIS operating unit about a first axis or a second axis or rotate it within a preset angle range. In this embodiment, the OIS operating unit includes the lens module 400 and the image sensor 810. Therefore, when the OIS is driven, the tilting direction (or rotation direction) and tilting angle (or rotation angle) of the lens module (e.g., lens or lens barrel) 400 (or bobbin 110) may be the same as or approximately the same as the tilting direction (or rotation direction) and tilting angle (or rotation angle) of the image sensor 810.

[0368] In this embodiment, when the OIS is activated, the lens module 400 (or bobbin 110) and the image sensor 810 can tilt or rotate together, resulting in no image distortion, 100% image resolution, and wide-angle image stabilization or shake correction.

[0369] In addition, in the embodiment, wideband shake correction is possible because the OIS operating unit including the lens module 400 (or bobbin 110) and the image sensor 810 tilts or rotates. In addition, in the embodiment, image correction without mechanical distortion is possible, so compared to Comparative Examples 1 and 2, the load on the image processing is smaller and current consumption can be reduced.

[0370] Furthermore, in this embodiment, since a moving plate 60 is used to tilt the OIS operating part, the OIS operating part can be tilted stably, precisely and accurately compared to examples that simply use a ball member or a shaft member, etc., thereby improving the reliability of the OIS drive.

[0371] In addition, in this embodiment, the bent portions 804D, 804E and the third portion 804C of the fourth substrate 804, which is a flexible substrate of the circuit board 800, can reduce the power consumption required to drive the OIS.

[0372] In addition, in the embodiment, the moving plate 60 is disposed within the seating portion 25A of the sensor base 270, and the protrusion 28 of the sensor base 270 overlaps with the opening 60A of the moving plate 60, so that the height or length of the camera device 200 in the optical axis direction can be reduced.

[0373] In addition, in the embodiment, at least a portion of the magnet 31 is positioned within the opening 60A of the moving plate 60, so that the distance between the magnet 31 and the magnetic body 32 can be reduced, thereby increasing the attractive force or holding force for supporting the OIS operating part, and enabling stable OIS operation.

[0374] FIG. 14 is a perspective view of a camera device 200 including a lens module 400. As shown in FIG.

[0375] 14, the lens module 400 may be coupled to the bobbin 100 and may move together with the bobbin 110 in the optical axis direction. For example, the lens module 400 may include at least one of a lens and a lens barrel.

[0376] In an embodiment, during image stabilization or shake correction, the lens module 400 and the image sensor 810 may simultaneously tilt along the X axis or the Y axis by the same angle in the same direction.

[0377] 15a shows the OIS operating portion 100 in a first position, and FIG. 15b shows the OIS operating portion 100 in a second position.

[0378] 14, 15a, and 15b, the force F1 generated by the interaction between the first magnet unit 310A and the first coil unit 230A can tilt the OIS operation unit 100 by a preset angle θ1. For example, the force F1 can tilt the AF movement unit and the OIS operation unit together by the preset angle θ1.

[0379] That is, when the OIS operating unit 100 moves from the first position to the second position, the image sensor 810 and the lens module 400 can simultaneously tilt by the preset angle θ1. Also, when the OIS operating unit 100 moves from the first position to the second position, the moving plate 60 can tilt by the preset angle θ1 together with the image sensor 810 and the lens module 400.

[0380] Therefore, the embodiment can obtain 100% image resolution without image distortion and can perform wide-angle image stabilization or shake correction. The description of Figures 20a and 20b can also be applied to the X-axis tilting of the OIS operating unit 100, or can be applied by analogy.

[0382] 16 to 27, a camera device 1200 can include a fixed unit, an AF moving unit, an OIS operating unit (or vibration unit) 1100, and a support unit. The operating unit 1100 can be expressed interchangeably as a "moving unit" or an "operating unit."

[0383] The fixed portion may be a fixed element. That is, the fixed portion may not move in the optical axis direction. Alternatively, the fixed portion may not move or tilt in a direction perpendicular to the optical axis. Also, a structure coupled to the fixed portion may correspond to the fixed portion.

[0384] The fixing portion may include a housing 1210. The fixing portion may include a cover member 1300. For example, the fixing portion may include a configuration disposed on or coupled to the housing 1210 or the cover member 1300. For example, the fixing portion may include any one of a magnet 1310, a magnet 1031, and a movement suppressing portion 1080 disposed on the housing 1210.

[0385] The AF moving unit can move in the optical axis direction relative to the fixed unit. For example, the AF moving unit can include a bobbin 1110. In another embodiment, the AF moving unit can further include a structure (e.g., a magnet 1130) coupled to the bobbin 1110. In another embodiment, the AF moving unit can further include a lens module 1400 (see FIG. 19 ) coupled to the bobbin 1110.

[0386] The OIS operating unit 1100 (see FIG. 17a) can move or tilt left and right relative to the fixed unit about a first axis (e.g., X-axis (e.g., Pitch)) perpendicular to the optical axis. The OIS operating unit can also move or tilt left and right relative to the fixed unit about a second axis (e.g., Y-axis (e.g., Yaw)) perpendicular to the optical axis.

[0387] For example, the OIS operating unit may include an AF movement unit. The OIS operating unit may also include an image sensor 1810. The OIS operating unit may also include a circuit board 1800 on which the image sensor 1810 is disposed. The OIS operating unit may also include a sensor base 1270 on which at least a portion of the circuit board 1800 is disposed. The OIS operating unit may also include a holder 1140 coupled to the sensor base 1270.

[0388] The OIS operating unit may be referred to as a first moving unit (or a first operating unit), and the AF moving unit may be referred to as a second moving unit (or a second operating unit). For example, the first moving unit may include the sensor base 1270 and the circuit board 1800.

[0389] Furthermore, for example, the OIS operating unit may include a component disposed on or coupled to any one of the holder 1140, the sensor base 1270, and the circuit board 1800. For example, the OIS operating unit may include a coil 1230 disposed on the holder 1140. For example, the OIS operating unit may include a magnetic material 1032 disposed on the sensor base 1270. For example, the OIS operating unit may include any one of the image sensor 1810, the sensors 1170, 1240, the coils 1120, 1230, the circuit element 1815, and the control unit 1830 disposed on the circuit board 1800.

[0390] The support portion can support the OIS operating portion relative to the fixed portion, for example, the support portion can include a moving plate 1060. In other embodiments, for example, the support portion can further include a rolling member (e.g., a ball member) or a sliding member (e.g., a shaft).

[0391] The bobbin 1110 is for housing a lens or lens barrel and may be placed in a holder 1140. The bobbin 1110 may also be referred to interchangeably as a "lens holder" or a "lens carrier."

[0392] The bobbin 1110 can move in the optical axis direction. For example, the bobbin 1110 can move in a first direction (e.g., the Z-axis direction) due to electromagnetic interaction between the coil 1120 and the magnet 1130. The coil 1120 and the magnet 1130 can be an AF drive unit that moves or drives an AF drive unit.

[0393] Also, the bobbin 1110 is included in the OIS operating unit, and the bobbin 1110 can tilt around a first axis or a second axis or rotate by a preset angle.

[0394] 20, the bobbin 1110 may include an opening 1101 for coupling with the lens module 1400. The shape of the opening 1101 of the bobbin 1110 may match the shape of the lens module 1400 to be attached, and may be, for example, but not limited to, a circle, an ellipse, or a polygon.

[0395] 16, the bobbin 1110 may include at least one stopper disposed on at least one of the upper and lower surfaces. The stopper of the bobbin 1110 has a structure that protrudes in a first direction or upward (or downward) from the upper surface (or lower surface) of the bobbin 1110, and can prevent the upper surface of the bobbin 1110 from directly hitting the inner surface of the upper plate 1301 of the cover member 1300 (or the lower part of the holder 1140).

[0396] The bobbin 1110 may include a seat 1115 for seating or positioning the magnet 1130. For example, the seat 1115 may be a groove recessed from the outer surface of the bobbin 1110.

[0397] 21, the bobbin 1110 can include multiple side surfaces 1110A to 1110D or outer surfaces. For example, the bobbin 1110 can include a first side surface 1110A, a second side surface 1110B, a third side surface 1110C, and a fourth side surface 1110D.

[0398] For example, the second side surface 1110B may face the first side surface 1110A or may be located on the opposite side of the first side surface 1110A relative to the optical axis OA. The third side surface 1110C and the fourth side surface 1110D may be located between the first side surface 1110A and the second side surface 1110B. For example, the fourth side surface 1110D may face the third side surface 1110C or may be located on the opposite side of the third side surface 1110C relative to the optical axis OA. While FIG. 21 illustrates a bobbin 1110 including four sides, other embodiments may include three or five or more sides.

[0399] For example, the seat 1115 may be formed on the first side 1110A of the bobbin. For example, the lower portion of the seat 1115 may be closed without opening at the lower surface of the bobbin 1110. Also, the upper portion of the seat 1115 may be closed without opening at the upper surface of the bobbin 1110. In other embodiments, for example, the seat 1115 may include an opening that opens at at least one of the upper surface or the lower surface of the bobbin 1110.

[0400] The bobbin 1110 may include a receiving portion 1112 for receiving at least a portion of the rolling member 1021. For example, at least a portion of the receiving portion 1112 may be disposed on a first side surface 1110A of the bobbin 1110. The receiving portion 1112 may be a groove recessed from an outer surface (e.g., the first side surface 1110A) of the bobbin 1110. The receiving portion 1112 may be interchangeably referred to as an "accommodating groove," "groove," or "guide groove." A lubricant (e.g., grease) may be disposed within the receiving portion 1112 of the bobbin 1110 to reduce friction with the rolling member 1021.

[0401] For example, the bobbin 1110 may include a first receiving portion 1112A for receiving the rolling member 1021A and a second receiving portion 1112B for receiving the rolling member 1021B. For example, the seat 1115 may be disposed between the first receiving portion 1112A and the second receiving portion 1112B.

[0402] For example, the first receiving portion 1112A (or the second receiving portion 1112B) may include an opening that opens to the top surface of the bobbin 1110. In other embodiments, the tops of the receiving portions 1112A, 1112B may be closed without opening to the top surface of the bobbin 1110. For example, the bottoms of the receiving portions 1112A, 1112B may be closed without opening to the bottom surface of the bobbin 1110.

[0403] For example, the receiving portion 1112 may be formed to extend in the optical axis direction. For example, the receiving portion 1112 may be formed between the upper surface and the lower surface of the bobbin 1110 and extend in the optical axis direction.

[0404] For example, when viewed from above, the shape of the receiving portion 1112 may be, but is not limited to, a triangular shape, and may be a polygon (e.g., a square or a pentagon, etc.). Alternatively, for example, when viewed from above, the receiving portion 1112 may be a "V" or "U" shape.

[0405] The magnet 1130 may be disposed on, coupled to, or fixed to the bobbin 1110. For example, the magnet 1130 may be disposed on or coupled to the first side 1110A of the bobbin 1110. For example, the magnet 1130 may be disposed within or coupled to the seat 1115 of the bobbin 1110. For example, the magnet 1130 may be disposed between the first rolling member 1021A and the second rolling member 1021B.

[0406] The shape of the magnet 1130 may be, for example, a rectangular parallelepiped shape, corresponding to the first side surface 1110A of the bobbin 1110. In another embodiment, for example, at least one of both ends of the magnet 1130 may be tapered.

[0407] For example, the magnet 1130 may include a first side 1013A facing the coil 1120 and a second side 1013B opposite the first side 1013A. The first side 1013A of the magnet 1130 may be exposed from the first side 1110A of the bobbin 1110.

[0408] Furthermore, to increase the electromagnetic force, the magnet 1130 may be a four-pole magnet. For example, the magnet 1130 may include two north poles and two south poles. For example, the magnet 1130 may include a first magnet including a north pole and a south pole, a second magnet including a south pole and a north pole, and a partition wall disposed between the first and second magnets. Here, the partition wall is a substantially non-magnetic portion and may include a section with almost no polarity. It may be filled with air or made of a non-magnetic material and may also be referred to as a "neutral zone." For example, the first and second magnets may face each other in the optical axis direction, and the first and second magnets may be disposed so that their opposite polarities face each other in the optical axis direction.

[0409] In another embodiment, magnet 1130 may be a two-pole magnet having two opposite polarities and a naturally formed boundary between the opposite polarities. For example, in another embodiment, magnet 1130 may include one north pole and one south pole. For example, magnet 1130 may be a magnet that is divided or arranged with a north pole and a south pole in the optical axis direction. In another embodiment, magnet 1130 may be a two-pole magnet that is divided with a north pole and a south pole in a direction perpendicular to the optical axis.

[0410] The holder 1140 may be disposed inside the cover member 1300. The holder 1140 may include a cavity for accommodating the bobbin 1110. The holder 1140 may include an opening 1030A corresponding to the opening 1101 of the bobbin 1110. For example, the opening 1030A may be a through-hole or a hollow for exposing at least a portion of the bobbin 1110 (or the lens module 1400). Also, for example, the opening 1030A of the holder 1140 may expose an imaging area of ​​the image sensor 1810. The holder 1140 may also be expressed interchangeably as a "housing."

[0411] For example, the opening 1030A may be located in the center or central region of the holder 1140. For example, the opening 1030A of the holder 1140 may be a through-hole or a hollow that penetrates the holder 1140 in the optical axis direction. The opening 1030A of the holder 1140 may have a shape that corresponds to the shape of the bobbin 1110, for example, a polygon (e.g., a square or an octagon) or a circle (or an ellipse), but is not limited thereto, and may have various shapes.

[0412] The holder 1140 may include a plurality of sides 1041A to 1041D. The holder 1140 may include a corner located between and connecting two adjacent sides.

[0413] The holder 1140 may include a first side 1041A corresponding to or facing the first side 1110A of the bobbin 1110, a second side 1041B corresponding to or facing the second side 1110B of the bobbin 1110, a third side 1041C corresponding to or facing the third side 1110C of the bobbin 1110, and a fourth side 1041D corresponding to or facing the fourth side 1110D of the bobbin 1110.

[0414] The first side 1041A (or first side surface or first outer surface) of the holder 1140 may be located opposite the second side 1041B (or second side surface or second outer surface) of the holder 1140 based on the optical axis, and the third side 1041C (or third side surface or third outer surface) of the holder 1140 may be located opposite the fourth side 1041D (or fourth side surface or fourth outer surface) of the holder 1140 based on the optical axis.

[0415] Each of the first to fourth side portions 1041A to 1041D of the holder 1140 can be arranged parallel to a corresponding one of the side plates 1302 of the cover member 1300.

[0416] 22a and 22b, the holder 1140 may include a seat 1142A for disposing the coil 1120. For example, the seat 1142A may be disposed or formed on the first side 1041A of the holder 1140. For example, the seat 1142A may be a through-hole formed through the first side 1041A of the holder 1140. Because the seat 1142A is in the form of a through-hole, a part of the holder 1140 does not need to be interposed between the coil 1120 and the magnet 1130, thereby increasing the electromagnetic force between the magnet 1130 and the coil 1120. Furthermore, because a part of the holder 1140 does not need to be interposed between the position sensor 1170 and the magnet 1130, the output of the position sensor 1170 may be increased, thereby improving the sensitivity of the position sensor 1170.

[0417] In another embodiment, the seat 1142A may be a groove recessed from the outer surface (or inner surface) of the first side 1041A of the holder 1140.

[0418] The holder 1140 may include a groove 1142 in which at least a portion of the circuit board 1800, for example, at least a portion of the second board 1802, is disposed. Because at least a portion of the second board 1802 is disposed in the groove 1142 of the holder 1140, the second board 1802 and the magnetic material 1082 may not protrude from the outer surface of the first side 1041A of the holder 1140, or may not protrude excessively from the outer surface of the first side 1041A. That is, the second board 1802 and the magnetic material 1082 may protrude less than the sum of the thicknesses of the second board 1802 and the magnetic material 1082 from the outer surface of the first side 1041A of the holder 1140. This prevents the size of the camera device 1200 from increasing in the direction perpendicular to the optical axis.

[0419] 22a and 22b, the holder 1140 may include a receiving portion 1116 for disposing or receiving at least a portion of the rolling member 1021. For example, at least a portion of the receiving portion 1116 may be disposed on the first side portion 1041A of the holder 1140. The receiving portion 1116 may be a groove recessed from the inner surface of the holder 1140 (e.g., the inner surface of the first side portion 1041A). The receiving portion 1116 may be referred to interchangeably as an "receiving groove," "groove," or "guide groove."

[0420] At least a portion of the receiving portion 1116 of the holder 1140 may correspond to, face, or overlap with the receiving portion 1112 of the bobbin 1110 .

[0421] For example, the holder 1140 may include a first receiving portion 1116A for receiving at least another portion of the first rolling members B1 and B2 and a second receiving portion 1116B for receiving at least another portion of the second rolling members B3 and B4. For example, the seating portion 1142A of the holder 1140 may be disposed between the first receiving portion 1116A and the second receiving portion 1116B of the holder 1140.

[0422] For example, the first receiving portion 1116A (or the second receiving portion 1116B) may include an opening that opens to the top surface of the holder 1140. In other embodiments, the top of the receiving portion 1116 may be closed without opening to the top surface of the holder 1140. For example, the bottom of the receiving portion 1116 may be closed without opening to the bottom surface of the holder 1140.

[0423] For example, the receiving portion 1116 may be formed to extend in the optical axis direction. For example, the receiving portion 1116 may be formed between the upper surface and the lower surface of the holder 1140 and extend in the optical axis direction.

[0424] For example, when viewed from above, the shape of the receiving portion 1116 of the holder 1140 may be, but is not limited to, a triangular shape, and may be a polygonal shape (e.g., a square or a pentagon, etc.). Alternatively, for example, when viewed from above, the receiving portion 1116 may be "V" shaped or "U" shaped.

[0425] For example, when viewed in the optical axis direction or from above, the receiving portion 1116 may face or overlap the upper plate 1301 of the cover member 1300. For example, at least a portion of the upper plate 1301 of the cover member 1300 may cover the receiving portion 1116.

[0426] Camera device 1200 may include a rolling member 1021 disposed between bobbin 1110 and holder 1140. Rolling member 1021 may be interchangeably referred to as a "ball member," a "ball," or a "ball bearing."

[0427] At least a portion of the rolling member 1021 contacts the bobbin 1110 and the holder 1140, and can support movement of the bobbin 1110 in the optical axis direction by rolling or rotating between the bobbin 1110 and the holder 1140. When the bobbin 1110 moves in the optical axis direction, the rolling member 1021 can reduce friction between the bobbin 1110 and the holder 1140. The rolling or rotation of the rolling member 1021 allows the bobbin 1110 to slide or glide in the optical axis direction while contacting the rolling member 1021.

[0428] For example, the rolling member 1021 may be made of, but is not limited to, a metal material, a plastic material, or a resin material. The rolling member 1021 may have a circular shape and may have a diameter large enough to support the movement of the bobbin 1110 in the optical axis direction.

[0429] For example, the rolling member 1021 may be disposed between an outer surface of the bobbin 1110 and an inner surface of the holder 1140. For example, the rolling member 1021 may be disposed between a first side surface 1110A of the bobbin 1110 and a first side 1041A of the holder 1140. For example, the rolling member 1021 may be disposed between the receiving portion 1112 of the bobbin 1110 and the receiving portion 1116 of the holder 1140.

[0430] For example, at least a portion of the rolling member 1021 may contact the receiving portion 1112 of the bobbin 1110 , and at least another portion of the rolling member 1021 may contact the receiving portion 1116 of the holder 1140 .

[0431] The rolling member 1021 may include at least one ball member. For example, the rolling member 1021 may include two or more ball members B1 to B4.

[0432] For example, the rolling member 1021 may include a first rolling member 1021A disposed between the first receiving portion 1112A of the bobbin 1110 and the first receiving portion 1116A of the holder 1140, and a second rolling member 1021B disposed between the second receiving portion 1112B of the bobbin 1110 and the second receiving portion 1116B of the holder 1140. For example, the first rolling member 1021A may include at least one ball. For example, the first rolling member 1021A may include a plurality of balls B1 and B2.

[0433] The second rolling member 1021B may include at least one ball. For example, the second rolling member 1021B may include a plurality of balls B3 and B4. In other embodiments, the first rolling member 1021A and the second rolling member 1021B may each include one ball.

[0434] For example, each of the first rolling member 1021A and the second rolling member 1021B may include three or more balls. For example, each of the first rolling member 1021A and the second rolling member 1021B may include a highest ball located at the top, a lowest ball located at the bottom, and at least one intermediate ball located between the highest and lowest balls. For example, the diameter of the highest 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 highest ball and the lowest ball may be the same. In yet another embodiment, the diameters of the highest ball, the lowest ball, and the intermediate ball may be the same.

[0435] For example, each of the first rolling member 1021A and the second rolling member 1021B may include a first ball (highest ball), a second ball (lowest ball), and a third ball (middle ball) arranged in the optical axis direction, and the diameter of the first ball may be larger than the diameter of the third ball. Also, the diameter of the second ball may be larger than the diameter of the third ball. For example, the diameters of the first ball and the third ball may be the same. In another embodiment, the diameter of the first ball may be larger than the diameter of the second ball. In yet another embodiment, the diameter of the first ball may be smaller than the diameter of the second ball. In yet another embodiment, the diameters of the first ball, the second ball, and the third ball may be the same.

[0436] For example, the diameter of the first ball and the diameter of the second ball may each be 0.85 mm or more and 0.95 mm or less, and the diameter of the third ball may be 0.75 mm or more and 0.85 mm or less.

[0437] In yet another embodiment, each of the first rolling member 1021A and the second rolling member 1021B may include four balls, the diameter of the highest ball and the diameter of the lowest ball may be greater than or equal to 0.85 mm and less than or equal to 0.95 mm, and the diameter of each of the two intermediate balls may be greater than or equal to 0.75 mm and less than or equal to 0.85 mm.

[0438] When viewed from above, the coil 1120 and the magnet 1130 may be located between the first rolling member 1021A and the second rolling member 1021B. This is to prevent the bobbin 1110 from moving in the tilted state when the bobbin 1110 moves in the optical axis direction, and to stably support the bobbin 1110, thereby improving the reliability of autofocusing.

[0439] In other embodiments, each of the first rolling member 1021A and the second rolling member 1021B may be in the form of a shaft or a roller. In other embodiments, instead of the ball members 1021A and 1021B, a sliding member (e.g., a shaft) or a roller may be included.

[0440] The camera device 1200 may include a magnetic body 1082 that exerts an attractive force on the magnet 1130. For example, an attractive force may act between the magnetic body 1082 and the magnet 1130 in a direction perpendicular to the optical axis (or a second direction). For example, the magnetic body 1082 may be disposed in the holder 1140. In another embodiment, the magnetic body 1082 may be disposed in the housing 1210.

[0441] The magnetic body 1082 may be made of a material that attracts a magnet. For example, the magnetic body 1082 may be made of a metal material that attracts a magnet. Alternatively, for example, the magnetic body 1082 may be made of a metal material that has magnetic properties. Alternatively, for example, the magnetic body 1082 may be a magnet. The magnetic body 1082 may be expressed interchangeably as a "yoke." The magnetic body 1082 may increase or serve to increase the electromagnetic force between the magnet 1130 and the coil 1120.

[0442] Since the magnet 1130 is disposed on the bobbin 1110 and the magnetic material 1082 is disposed on the holder 1140, the attractive force acting between the magnetic material 1082 and the magnet 1130 can pull the bobbin 1110 toward the holder 1140 on which the magnetic material 1082 is disposed. The attractive force between the magnetic material 1082 and the magnet 1130 can cause the bobbin 1110 and the holder 1140 to press the rolling member 1021, thereby stably supporting the bobbin 1110. The magnetic material 1082 and the magnet 1130 can be a "pressing unit" or "pressing member." Such a pressing unit can maintain contact between the bobbin 1110 and the rolling member 1021 and between the holder 1140 and the rolling member 1021 when the bobbin 1110 moves in the optical axis direction. That is, the attractive force between the magnet 1130 and the magnetic body 1082 allows the rolling member 1021 to stably support the bobbin 1110 relative to the holder 1140 .

[0443] In another embodiment, the magnet 1130 may be disposed on the holder 1140, and the coil 1120 may be disposed on the bobbin 1110. For example, the magnetic material 1082 may be disposed on the holder 1140 together with the magnet 1130. For example, the magnet 1130 may be disposed between the magnetic material 1082 and the coil 1120. In yet another embodiment, the magnetic material 1082 may be disposed on the bobbin 1110 together with the coil 1120, facing the magnet 1130 disposed on the holder 1140. The camera device 1200 may further include a conductive member, for example, a conductive member, for electrically connecting the coil 1120 disposed on the bobbin 1110 and the second board 1802 of the circuit board 1800.

[0444] 22b, the holder 1140 may include a seat 1045A for seating or positioning the filter 1610. The seat 1045A may be disposed on or formed on the lower surface of the holder 1140. For example, the seat 1045A may be a groove recessed from the lower surface of the holder 1140. For example, the seat 1045A may include a bottom surface 1005A that is stepped in the optical axis direction relative to the lower surface of the holder 1140, and a side surface 1005B that connects the lower surface of the holder 1140 and the bottom surface 1005A of the seat 1045A. For example, the opening 1030A may be formed through the bottom surface 1005A of the seat 1045A.

[0445] The holder 1140 may include a recess 1045B disposed or formed in a corner region of the inner surface of the seat 1045A. The recess 1045B may have a recessed structure in a direction from the optical axis toward the corner region of the inner surface of the seat 1045A. The recess 1045B may prevent an adhesive (e.g., UV epoxy) used to attach or bond the filter 1610 to the seat 1045A from overflowing outside the seat 1045A.

[0446] The holder 1140 may include an escape groove 1046 to avoid spatial interference with the circuit element 1815. For example, the escape groove 1046 may be disposed or formed on the lower surface of the holder 1140. For example, the escape groove 1046 may be recessed from the lower surface of the holder 1140.

[0447] The escape groove 1046 may correspond to, face, or overlap with the circuit element 1815 in the optical axis direction. For example, the escape groove 1046 may be located between the seat 1045A and an edge of the lower surface of the holder 1140. For example, the escape groove 1046 may include a first escape groove 1046A and a second escape groove 1046B located on opposite sides of the seat 1045A or the filter 1610. In another embodiment, the escape groove 1046 may include four escape grooves located between the opening 1030A and the four edges of the holder 1140.

[0448] The holder 1140 may include a groove 1047 corresponding to the protrusion 1216 of the sensor base 1270. The protrusion 1216 of the sensor base 1270 and the groove 1047 of the holder 1140 may serve as a guide for easily assembling the sensor base 1270 and the holder 1140, and may increase the bonding area and thereby increase the bonding strength between the sensor base 1270 and the holder 1140.

[0449] For example, the groove 1047 may be recessed from the lower surface of the holder 1140. For example, the groove 1047 may be disposed or formed in a corner or corner region of the lower surface of the holder 1140. The groove 1047 of the holder 1140 may have a shape corresponding to the protrusion 1216 of the sensor base 1270. The holder 1140 may also include a groove 1048 or hole corresponding to the protrusion 1017 of the sensor base 1270. For example, the protrusion 1017 of the sensor base 1270 may be inserted into or coupled with the groove 1048 of the holder 1140. For example, the groove 1048 may be disposed or formed in the bottom surface of the groove 1047 of the holder 1140. For example, the groove 1048 may be recessed from the bottom surface of the groove 1047 of the holder 1140.

[0450] In other embodiments, holder 1140 may include a protrusion protruding from the bottom surface of holder 1140 instead of groove 1047, and sensor base 1270 may include a groove recessed from the top surface of sensor base 1270 and coupled with the protrusion of holder 1140 instead of protrusion 1216. In still other embodiments, protrusion 1017 may be formed on holder 1140, and groove 1048 may be formed on sensor base 1270.

[0451] Camera device 1200 may include a filter 1610 disposed on or coupled to holder 1140. For example, filter 1610 may be disposed below holder 1140. For example, filter 1610 may be coupled to the underside of holder 1140. For example, filter 1610 may be disposed on seat 1045A of holder 1140.

[0452] The filter 1610 may serve to block light of a specific frequency band from passing through the lens module 1400 from entering the image sensor 1810. For example, the filter 1610 may be an infrared blocking filter. For example, the filter 1610 may be disposed parallel to a plane perpendicular to the optical axis OA.

[0453] The filter 1610 can be bonded to the holder 1140 (or seat 1045A) by an adhesive (not shown). For example, an edge region of the filter 1610 can be bonded to the bottom surface of the seat 1045A.

[0454] For example, the adhesive may be an epoxy, a heat-curable adhesive, an ultraviolet-curable adhesive, etc. For example, at least a portion of the filter 1610 may correspond to, face, or overlap with the lens module 1400 or / and the image sensor 1810 in the optical axis direction.

[0455] The sensor base 1270 may be disposed below the holder 1140. The sensor base 1270 may be coupled to the holder 1140. The sensor base 1270 may be interchangeably referred to as a "holder." The holder 1140 may also be interchangeably referred to as a "first housing" (or a "first holder"), and the sensor base 1270 may also be interchangeably referred to as a "second housing" (or a "second holder"). The holder 1140 and the sensor base 1270 may not be separately expressed, but may be interchangeably expressed by a single term, for example, "housing" (or holder). In another embodiment, the sensor base 1270 and the holder 1140 may be integrally formed.

[0456] For example, the sensor base 1270 may include a protrusion 1216 that protrudes from the top surface. The protrusion 1216 may be expressed interchangeably as a "pillar."

[0457] For example, the protrusion 1216 may correspond to, face, or overlap with the groove 1047 of the holder 1140 in the optical axis direction. At least a portion of the protrusion 1216 of the sensor base 1270 may be inserted into the groove 1047 of the holder 1140. For example, at least a portion of the protrusion 1216 may be coupled with the groove 1047 of the holder 1140. For example, at least a portion of the protrusion 1216 may be coupled with the groove 1047 of the holder 1140 by an adhesive.

[0458] For example, the sensor base 1270 may include a body 1270A and a protrusion 1216 protruding from an upper surface of the body 1270A. For example, the body 1270A may have a shape corresponding to the first board 1801 of the circuit board 810. For example, the body 1270A may have a polyhedron shape, such as a hexahedron shape. For example, the protrusion 1216 may be disposed in corner regions of the upper surface of the body 1270A. For example, the protrusion 1216 may include four protrusions 1216A to 1216D disposed in four corner regions of the upper surface of the body 1270A. Also, for example, the holder 1140 may include four grooves 1047 corresponding to the four protrusions 1216A to 1216D. In other embodiments, the housing 1210 may include at least one protrusion disposed in at least one of the four corner regions of the upper surface of the body 1270A, and the holder 1140 may include at least one groove 1048 corresponding to the at least one protrusion of the housing 1210.

[0459] The sensor base 1270 or body 1270A can include sides 1051A to 1051D that correspond to, face, or overlap sides 1041A to 1041D of the holder 1140.

[0460] The camera device 1200 may include a gyro sensor (not shown) disposed on the circuit board 1800. For example, the gyro sensor may be disposed on a first substrate 1801 of the circuit board 1800. For example, the gyro sensor may be disposed on, coupled to, or fixed to the lower surface of the first substrate 1801. For example, the gyro sensor outputs rotational angular velocity information resulting from the operation of the camera device 1200. For example, the gyro sensor may be embodied as a two-axis or three-axis gyro sensor or an angular velocity sensor. For example, the gyro sensor may be conductively or electrically connected to the first substrate 1801.

[0461] In another embodiment, the sensor base 1270 may include a receiving portion in which the gyro sensor is disposed or to avoid spatial interference with the gyro sensor. For example, the receiving portion may be a through-hole that penetrates the sensor base 1270 in the optical axis direction, or a groove that is recessed from the upper surface of the sensor base 1270 or the upper surface of the body 1270A. Here, the receiving portion may include an opening that opens to the outer surface of the sensor base 1270.

[0462] The sensor base 1270 may include a receiving portion 1055 in which the control unit 1830 is disposed or for receiving the control unit 1830. The receiving portion 1055 may be a groove recessed from the upper surface of the sensor base 1270 or the upper surface of the body 1270A. In another embodiment, the receiving portion 1055 may be a through-hole formed through the sensor base 1270 or the body 1270A in the optical axis direction.

[0463] The sensor base 1270 may include seats 1274A, 1274B for positioning the coil 1230. The seats 1274A, 1274B may be disposed on or formed on the top surface of the sensor base 1270. For example, the seats 1274A, 1274B may be grooves recessed from the top surface of the sensor base 1270.

[0464] For example, the sensor base 1270 may include a first seat 1274A for placing the first coil unit 1230A and a second seat 1274B for placing the second coil unit 1230B.

[0465] For example, the first seating portion 1274A may be formed adjacent to or in contact with the second side 1051B of the sensor base 1270. For example, the first seating portion 1274A may be a groove formed in the upper surface of the sensor base 1270 adjacent to the second side 1051B of the sensor base 1270. For example, the first seating portion 1274A may include an opening that opens to the outer surface of the second side 1051B of the sensor base 1270. In other embodiments, the first seating portion 1274A may be spaced apart from the outer surface of the second side 1051B of the sensor base 1270 and may not include an opening that opens to the outer surface of the second side 1051B.

[0466] For example, the second seating portion 1274B may be formed adjacent to or in contact with the third side 1051C of the sensor base 1270. For example, the second seating portion 1274B may be a groove formed in the upper surface of the sensor base 1270 adjacent to the third side 1051C of the sensor base 1270. For example, the second seating portion 1274B may include an opening that opens to the outer surface of the third side 1051C of the sensor base 1270. In other embodiments, the second seating portion 1274B may be spaced apart from the outer surface of the third side 1051C of the sensor base 1270 and may not include an opening that opens to the outer surface of the third side 1051C.

[0467] In another embodiment, the seats 1274A and 1274B may be in the form of a through-hole. For example, one of the first and second seats 1274A and 1274B may be a hole or a through-hole that penetrates the sensor base 1270 in the optical axis direction. In this case, a part of the sensor base 1270 may not be interposed between the coil 1230 and the magnet 1310, thereby increasing the electromagnetic force between the magnet 1310 and the coil 1230. In addition, because a part of the sensor base 1270 may not be interposed between the position sensor 1240 and the magnet 1310, the output of the position sensor 1240 may be increased, thereby improving the sensitivity of the position sensor 1240.

[0468] 22b, the sensor base 1270 may include a receiving portion 1028A for receiving the magnetic material 1032. The receiving portion 1028A may be disposed or formed on the lower portion or bottom surface of the sensor base 1270. For example, the receiving portion 1028A may be a groove recessed from the lower portion or bottom surface of the sensor base 1270. For example, the receiving portion 1028A may be disposed or formed on the bottom surface of the body 1270A. For example, the receiving portion 1028A may have a shape corresponding to the magnetic material 1032.

[0469] In an embodiment in which the positions of the magnetic body 1032 and the magnet 1031 are reversed, the magnet 1031 may be disposed in the receiving portion 1028A of the sensor base 1270 and the magnetic body 1032 may be disposed in the receiving portion 1049A of the housing 1210.

[0470] The sensor base 1270 may include grooves 1029 for receiving or accommodating at least a portion of the moving plate 1060 (e.g., the protrusions 1065). The grooves 1029 may be formed in the lower surface of the sensor base 1270. For example, the grooves 1029 may be recessed from the lower surface of the sensor base 1270. The number of grooves 1029 may be the same as the number of protrusions 1065 of the moving plate 1060.

[0471] For example, the groove 1029 may include two grooves 1029A and 1029B spaced apart from each other. For example, the two grooves 1029A and 1029B may be spaced apart from each other in the X-axis direction. For example, the receiving portion 1028A of the sensor base 1270 may be disposed between the two grooves 1029A and 1029B of the sensor base 1270.

[0472] The groove 1029 may contact the protrusion 1065 of the moving plate 1060 at at least one point. For example, the groove 1029 may include a bottom surface and at least one side surface connected to the bottom surface. The at least one side surface may be an inclined surface. For example, the groove 1029 may include a bottom surface and multiple inclined surfaces. The shapes of the inclined surfaces of the groove 1029 may be the same as each other. In other embodiments, at least one of the inclined surfaces of the groove 1029 may have a different shape from the rest.

[0473] 22a, a groove 1212A into which at least a portion of a first substrate 1801 of a circuit board 1800 is inserted or disposed may be formed in the protruding portion 1216 of the sensor base 1270. For example, a corner of the first substrate 1801 may be inserted into or coupled with the groove 1212A of the protruding portion 1216 of the sensor base 1270. For example, the groove 1212A may be formed on a side surface of the protruding portion 1216 that faces the corner of the circuit board 1800. In addition, a groove 1212A for being inserted into or coupled with the groove 1212A of the protruding portion 1216 may be formed in at least one corner of the circuit board 1800. The groove 1212A of the protrusion 1216 of the sensor base 1270 can serve as a coupling guide for coupling the first substrate 1801 and the sensor base 1270, and can also serve to prevent the first substrate 1801 from rotating or coming off the sensor base 1270.

[0474] The circuit board 1800 may be disposed on, coupled to, or fixed to the sensor base 1270. For example, the circuit board 1800 may be coupled to the sensor base 1270 by an adhesive or a fastener.

[0475] The circuit board 1800 may be disposed on, coupled to, or fixed to the body 1270A of the sensor base 1270. The circuit board 1800 may include any one of a rigid printed circuit board (Rigid PCB), a flexible printed circuit board (Flexible PCB), and a rigid-flexible printed circuit board (RigidFlexible PCB). For example, the circuit board 1800 may include a rigid printed circuit board and a flexible printed circuit board. The circuit board 1800 may be referred to as a "board unit," a "board," or a "printed circuit board."

[0476] For example, the circuit board 1800 may include a first substrate 1801 (or "first region") that is disposed on, coupled to, or secured to the sensor base 1270. For example, the first substrate 1801 may be disposed on, coupled to, or secured to the body 1270A of the sensor base 1270. For example, the bottom surface of the first substrate 1801 may be coupled to the top surface of the sensor base 1270 or the top surface of the body 1270A. For example, the bottom surface of the first substrate 1801 may be coupled to the top surface of the sensor base 1270 or the top surface of the body 1270A by adhesive.

[0477] The circuit board 1800 may include a second substrate 1802 (or "second region") coupled to the first substrate 1801 and disposed on, coupled to, or secured to the holder 1140. For example, the second substrate 1802 may be disposed on, coupled to, or secured to the first side 1041A of the holder 1140.

[0478] In FIG. 22a, the circuit board 1800 includes one second substrate, but in other embodiments, the circuit board 1800 may include multiple second substrates disposed on at least one of the sides of the holder 1140.

[0479] For example, the second substrate 1802 may be coupled to a first side surface of the first substrate 1801. For example, the second substrate 1802 may be bent from the first side surface of the first substrate 1801 toward the first side 1041A of the holder 1140. For example, the second substrate 1802 may extend upward from the first substrate 1801.

[0480] The circuit board 1800 may include a third board 1803 on which a connector 1805 is arranged or provided, and a fourth board 1804 that connects the first board 1801 and the third board 1803 together.

[0481] For example, the first substrate 1801 may be a rigid printed circuit board. For example, the second substrate 1802 may be a flexible printed circuit board. For example, the third substrate 1803 may be a rigid printed circuit board. For example, the fourth substrate 1804 may be a flexible printed circuit board.

[0482] For example, a rigid printed circuit board may include a plurality of conductive layers (or circuit patterns) spaced apart in the optical axis direction and an insulating layer disposed between two adjacent conductive layers among the plurality of conductive layers. For example, a flexible printed circuit board may include one conductive layer (or circuit pattern), a first insulating layer disposed on the conductive layer, and a second insulating layer disposed below the conductive layer. In another embodiment, a flexible printed circuit board may include a first conductive layer, a second conductive layer, 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.

[0483] The image sensor 1810 may be disposed on the first substrate 1801. The image sensor 1810 may be disposed to correspond to, face, or overlap with the lens module 1400 and / or the filter 1610 in the optical axis direction.

[0484] The image sensor 1810 may include an imaging area for sensing light. Here, the imaging area may be interchangeably referred to as an effective area, a light-receiving area, or an active area. For example, the imaging area may include a number of pixels on which an image is formed. The image sensor 1810 may be conductively or electrically connected to the first substrate 1801. The imaging area may correspond to, face, or overlap with the lens module 1400 and / or the filter 1610 in the optical axis direction.

[0485] The camera device 1200 may include a circuit element 1815 disposed on the first substrate 1801. For example, the circuit element 1815 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, to avoid spatial interference with the image sensor 1810, the circuit element 1815 may be disposed between the image sensor 1810 and an edge (e.g., a side) of the first substrate 1801.

[0486] The camera device 1200 may include a control unit 1830 disposed on the circuit board 1800. For example, the control unit 1830 may be a driver IC. For example, the control unit 1830 may be disposed on the first substrate 1801. For example, the control unit 1830 may be disposed below the first substrate 1801. For example, the control unit 1830 may be disposed on, coupled to, or fixed to the lower surface of the first substrate 1801. For example, the control unit 1830 may be conductively or electrically connected to the first substrate 1801.

[0487] For example, the control unit 1830 is electrically connected to the coil 1120 and can supply a driving signal to the first coil 1120. The control unit 1830 controls the coil unit 1230A, 1230B and are electrically connected to each other, and are capable of supplying a first drive signal to the first coil unit 1230A and a second drive signal to the second coil unit 1230B.

[0488] The control unit 1830 may be conductively or electrically connected to the position sensor 1170. The control unit 1830 may also be conductively or electrically connected to the position sensor 1240.

[0489] For example, the controller 1830 can receive the output signal of the position sensor 1170 and can use the output signal of the position sensor 1170 to control the drive signal (eg, drive current) provided to the coil 1120 .

[0490] For example, the controller 1830 can receive an output signal of the position sensor 1240 and use the output signal of the position sensor 1240 to control a drive signal (e.g., a drive current) supplied to the coil 1230. For example, the controller 1830 can receive an output signal of the first sensor 240A and use the output signal of the first sensor 240A to control a first drive signal (e.g., a first drive current) supplied to the first coil unit 1230A. The controller 1830 can also receive an output signal of the second sensor 240B and use the output signal of the second sensor 240B to control a second drive signal (e.g., a second drive current) supplied to the second coil unit 1230B.

[0491] The coils 1120, 1230 may be disposed on, coupled to, or fixed to the circuit board 1800 (e.g., the second board 1802). For example, the coil 1120 may be conductively or electrically connected to the circuit board 1800 (e.g., the second board 1802) by a conductive adhesive or solder. For example, the coil 1230 may be conductively or electrically connected to the circuit board 1800 (e.g., the first board 1801) by a conductive adhesive or solder.

[0492] The first coil unit 1230A and the second coil unit 1230B may be disposed on or coupled to the first substrate 1801 and may be conductively or electrically connected to the first substrate 1801. Referring to Fig. 22b, for example, the first coil unit 1230A and the second coil unit 1230B may be disposed on, coupled to, or fixed to the lower surface of the first substrate 1801. For example, the first coil unit 1230A and the second coil unit 1230B may be disposed between the first substrate 1801 and the sensor base 1270.

[0493] For example, the first and second coil units 1230A and 1230B may be disposed adjacent to two adjacent sides of the four sides of the first substrate 1801.

[0494] For example, the first coil unit 1230A may be disposed adjacent to a second side surface of the first substrate 1801 corresponding to the second side 1041B of the holder 1140, and the second coil unit 1230B may be disposed adjacent to a third side surface of the first substrate 1801 corresponding to the third side 1041C of the holder 1140. For example, at least a portion of the first coil unit 1230A may be disposed between the two protrusions 1216C and 1216D of the sensor base 1270, and at least a portion of the second coil unit 1230B may be disposed between the two protrusions 1216A and 1216D of the sensor base 1270.

[0495] The coil 1120 can move an AF moving part (for example, a bobbin) in the optical axis direction by interacting with the magnet 1130. The coil 1120 can be placed on a holder 1140.

[0496] The coil 1120 may be arranged to correspond to, face, or overlap with the magnet 1130 in a direction perpendicular to the optical axis. For example, the coil 1120 may be arranged on the holder 1140 to correspond to, face, or overlap with the magnet 1130 in a second direction (e.g., the X-axis direction) or in a direction from the first side 1041A to the second side 1041B of the holder 1140. For example, the coil 1120 may be arranged on the first side 1041A of the holder 1140. The coil 1120 may be arranged within the seating portion 1142A of the holder 1140.

[0497] For example, the coil 1120 may be hollow or include a hole. For example, the coil 1120 may have a ring shape or a closed curve shape. For example, the coil 1120 may be ring-shaped wound around a straight line that is perpendicular to the optical axis OA and perpendicular to the outer surface of the first side portion 1041A of the holder 1140. For example, the coil 1120 may be ring-shaped with a longer length in the horizontal direction (or third direction) than in the vertical direction (or optical axis direction).

[0498] A drive signal may be applied to the coil 1120 to generate an electromagnetic force through electromagnetic interaction with the magnet 1130. For example, the drive signal may be applied to the coil 1120 from the circuit board 1800 or the control unit 1830. Here, the drive signal supplied to the coil 1120 may be direct current and may be in the form of a voltage or current. Alternatively, in other embodiments, for example, the drive signal provided to the coil 1120 may include at least one of a direct current signal and an alternating current signal.

[0499] The coil 1120 to which the drive signal is provided can electromagnetically interact with the magnet 1130 disposed on the bobbin 1110, and the AF movement unit can move in a first direction due to the electromagnetic force generated by the electromagnetic interaction between the coil 1120 and the magnet 1130. The control unit 1830 can control the movement of the AF movement unit in the first direction by adjusting the magnitude and / or direction of the drive signal (e.g., drive current), thereby performing an autofocusing function.

[0500] For AF feedback drive, the camera device 1200 may include a position sensor 1170. The position sensor 1170 may sense the position or displacement of the bobbin 1110 in the optical axis direction. For example, the position sensor 1170 may sense the magnet 1130 disposed on the bobbin 1110. In another embodiment, a sensing magnet facing the position sensor 1170 may be disposed on the bobbin, separate from the magnet 1130, and the position sensor 1170 may sense the sensing magnet or the magnetic field of the sensing magnet to detect the displacement of the bobbin.

[0501] For example, the position sensor 1170 may be disposed in the holder 1140. For example, the position sensor 1170 may be disposed on the first side 1141A of the holder 1140. For example, the position sensor 1170 may be disposed in the seat 1142A of the holder 1140. For example, the position sensor 1170 may be disposed within the hollow of the coil 1120. In other embodiments, the position sensor 1170 may be disposed outside the hollow of the coil 1120.

[0502] For example, the position sensor 1170 can be coupled to the circuit board 1800. For example, the position sensor 1170 can be coupled to the circuit board 1800 by a conductive adhesive or solder. For example, the position sensor 1170 can be conductively or electrically connected to the second substrate 1802. For example, the position sensor 1170 can be conductively or electrically connected to the second substrate 1802 by a conductive adhesive or solder.

[0503] For example, the position sensor 1170 can be disposed on, coupled to, or fixed to a first surface of the second substrate 1802. For example, the position sensor 1170 can correspond to, face, or overlap with the magnet 1130 in a direction perpendicular to the optical axis or in a second direction.

[0504] The position sensor 1170 can sense the displacement of the bobbin 1110 in the optical axis direction.

[0505] For example, the position sensor 1170 can sense the magnetic field or the strength of the magnetic field of the magnet 1130 attached to the bobbin 1110 due to the movement of the bobbin 1110, and can output an output signal.

[0506] For example, the position sensor 1170 may be a Hall sensor. Here, the position sensor 1170 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 1800 may be conductively or electrically connected to the two input terminals and two output terminals of the position sensor 1170. The circuit board 1800 or the control unit 1830 may supply a driving signal to the two input terminals of the position sensor 1170, and the output signals output from the two output terminals of the position sensor 1170 may be transmitted to the circuit board 1800 or the control unit 1830.

[0507] In another embodiment, the position sensor 1170 may be implemented in the form of a driver IC including a Hall sensor. For example, if the position sensor 1170 is a driver IC including a Hall sensor, the position sensor 1170 may transmit and receive data to and from the outside using data communication using a protocol, for example, I2C communication.

[0508] For example, if the position sensor 1170 is a driver IC including a Hall sensor, the position sensor 1170 may include first and second terminals for receiving a power supply or a 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 1120. The first to sixth terminals of the position sensor 1170 may be conductively or electrically connected to the circuit board 1800.

[0509] The coil 1230, through interaction with the magnet 1310 arranged in the fixed part, the housing 1210, can tilt the OIS operating part or rotate it by a predetermined angle based on a first axis (e.g., the X axis) or a second axis (e.g., the Y axis).

[0510] The coil 1230 may include a first coil unit 1230A that corresponds to, faces, or overlaps with the first magnet unit 1310A in the optical axis direction, and a second coil unit 1230B that corresponds to, faces, or overlaps with the second magnet unit 1310B in the optical axis direction. For example, the coil 1230 does not have to overlap with the magnet 1310 in the direction perpendicular to the optical axis.

[0511] For example, coil 1230 may be positioned below coil 1120. For example, first coil unit 1230A may be positioned within first seat 1274A of sensor base 1270, and second coil unit 1230B may be positioned within second seat 1274B of sensor base 1270.

[0512] For example, the first and second coil units 1230A, 1230B Each of the first and second coil units may include a hollow or a hole. 1230A, 1230B Each of the first coil unit 1230A and the second coil unit 1230B may have a ring shape or a closed curve shape. For example, each of the first coil unit 1230A and the second coil unit 1230B may have a ring shape wound around a straight line that is parallel to the optical axis OA and perpendicular to the upper surface of the sensor base 1270 or the upper surface of the body 1270A.

[0513] For example, the first coil unit 1230A may be ring-shaped with a longer horizontal (or third) direction length than the vertical (or second) direction length. For example, the second coil unit 1230B may be ring-shaped with a longer vertical (e.g., second) direction length than the horizontal (or third) direction length.

[0514] For OIS feedback driving, the camera device 1200 may include a position sensor 1240. The position sensor 1240 may sense the displacement or angular displacement of the OIS operating unit 1100 due to tilting or rotation of the OIS operating unit.

[0515] For example, the position sensor 1240 may include a first sensor 1240A and a second sensor 1240B. For example, at least a portion of the first sensor 1240A may correspond to, face, or overlap with the first magnet unit 1310A in the optical axis direction. For example, the center of the first sensor 1240A may overlap with the first magnet unit 1310A in the optical axis direction. For example, the first sensor 1240A may sense the first magnet unit 1310A (or the magnetic field of the first magnet unit 1310A). For example, the first sensor 1240A may sense the tilt angle of the OIS operating unit 1100 based on the second axis (Y-axis).

[0516] At least a portion of the second sensor 1240B may correspond to, face, or overlap with the second magnet unit 1310B in the optical axis direction. For example, the center of the second sensor 1240B may overlap with the second magnet unit 1310B in the optical axis direction. For example, the second sensor 1240B may sense the second magnet unit 1310B (or the magnetic field of the second magnet unit 1310B). For example, the second sensor 1240A may sense the angle at which the OIS operating unit 1100 is tilted with respect to the first axis (X-axis).

[0517] For example, the first and second sensors 1240A, 1240B may be disposed on, coupled to, or fixed to the first substrate 1801 of the circuit board 1800. For example, the first and second sensors 1240A, 1240B may be conductively or electrically connected to the first substrate 1801.

[0518] For example, the first sensor 1240A may be disposed within the hollow (or hole) of the first coil unit 1230A, and the second sensor 1240B may be disposed within the hollow (or hole) of the second coil unit 1230B. In other embodiments, the first sensor 1240A may be disposed outside the hollow (or hole) of the first coil unit 1230A, and the second sensor 1240B may be disposed outside the hollow (or hole) of the second coil unit 1230B.

[0519] For example, each of the first sensor 1240A and the second sensor 1240B may 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 1240A may be conductively or electrically connected to the first substrate 1801, and the first and second input terminals and the first and second output terminals of the second sensor 1240B may be conductively or electrically connected to the first substrate 1801.

[0520] For example, the first substrate 1801 or the control unit 1830 is 1240A A first drive signal can be supplied or applied to the first and second input terminals of the first sensor. 1240AThe first sensor can output a first output signal, which can be transmitted to the first substrate 1801 or the control unit 1830. 1240A can be output to the first and second output terminals.

[0521] For example, the first substrate 1801 or the control unit 1830 may supply or apply a second drive signal to the first and second input terminals of the second sensor 1240B. The second sensor 1240B may output a second output signal, which may be transmitted to the first substrate 1801 or the control unit 1830. The second output signal may be output to the first and second output terminals of the second sensor 1240B.

[0522] In another embodiment, each of the first sensor 1240A and the second sensor 1240B may be a driver IC including a Hall sensor. The description of the embodiment in which the position sensor 1170 is a driver IC including a Hall sensor may also be applied or may be applied by analogy to the embodiment in which the first and second sensors 1240A and 1240B are driver ICs including Hall sensors.

[0523] The camera device 1200 may include a magnetic body 1082 disposed opposite the coil 1120 and the magnet 1130. For example, the magnetic body 1082 may be disposed on the holder 1140 or the second substrate 1802 of the circuit board 1800. For example, the magnetic body 1082 may be disposed to correspond to, face to, or overlap with the magnet 1130 in the second direction. Also, for example, the magnetic body 1082 may be disposed to correspond to, face to, or overlap with the coil 1120 in the second direction. For example, the coil 1120 may be disposed on a first surface of the second substrate 1802 facing the magnet 1130, and the magnetic body 1082 may be disposed on a second surface of the second substrate 1802 opposite the first surface of the second substrate 1802. The magnetic body 1082 may be coupled, attached, or fixed to the second substrate 1802 by an adhesive.

[0524] 25a and 25b, the housing 1210 may include a cavity for accommodating the OIS operating unit 1100. For example, the housing 1210 may have a shape corresponding to the OIS operating unit 1100, e.g., the holder 1140 or the sensor base 1270, such as, but not limited to, a polygonal (e.g., rectangular or octagonal) or circular (or elliptical) shape, and may have various shapes. The housing 1210 may be interchangeably referred to as a "base."

[0525] The housing 1210 may include multiple sides 1071A to 1071D that correspond to the sides 1041A to 1041D of the holder 1140 or the sides 1051A to 1051D of the sensor base 1270. The housing 1210 may include corners located between two adjacent sides.

[0526] The housing 1210 may also include a lower portion (or lower plate) 1042 positioned below the side portions 1071A to 1071D. The lower portion 1042 may be connected to the undersides of the side portions 1071A to 1071D. For example, the lower portion 1042 may be interchangeably referred to as a "bottom," "base," or "body." For example, the side portions 1071A to 1071D may protrude upward from the lower portion 1042.

[0527] The housing 1210 may include a first side 1071A that corresponds to, faces, or overlaps with the first side 1041A of the holder 1140, a second side 1071B that corresponds to, faces, or overlaps with the second side 1041B of the holder 1140, a third side 1071C that corresponds to, faces, or overlaps with the third side 1041C of the holder 1140, and a fourth side 1071D that corresponds to, faces, or overlaps with the fourth side 1041D of the holder 1140.

[0528] The first side 1071A (or first side surface or first outer surface) of the housing 1210 may be located opposite the second side 1071B (or second side surface or second outer surface) of the housing 1210, and the third side 1071C (or third side surface or third outer surface) of the housing 1210 may be located opposite the fourth side 1071D (or fourth side surface or fourth outer surface) of the housing 1210.

[0529] For example, each of the first to fourth side portions 1071A to 1071D of the housing 1210 may be disposed parallel to a corresponding one of the side plates 1302 of the cover member 1300.

[0530] The housing 1210 has a step portion disposed at the bottom of one of the side portions 1071A to 1071D. 1411 For example, the step portion 1411 may protrude from the outer surface of the side portions 1071A to 1071D of the housing 1210 in a direction perpendicular to the optical axis. For example, the step portion 1411 may face or overlap the side plate 1302 of the cover member 1300 in the optical axis direction. For example, the step portion 1411 may be bonded to the side plate 1302 of the cover member 1300 with an adhesive.

[0531] The housing 1210 may include seats 1141A and 1141B for accommodating the magnet 1310. For example, the seats 1141A and 1141B may be grooves formed in the lower portion 1042 of the housing 1210. In another embodiment, the seats 1141A and 1141B may be through-holes formed in the lower portion 1042 of the housing 1210.

[0532] The housing 1210 may include a first seat 1141A for disposing the first magnet unit 1310A and a second seat 1141B for disposing the second magnet unit 1310B. For example, the first seat 1141A may be disposed or formed in a first region of the lower portion 1042 of the housing 1210 adjacent to the second side 1071B of the housing 1210. For example, the second seat 1141B may be disposed or formed in a second region of the lower portion 1042 of the housing 1210 adjacent to the third side 1071C of the housing 1210.

[0533] The magnet 1310 may include a first magnet unit 1310A and a second magnet unit 1310B disposed in the lower portion 1042 of the housing 1210. For example, the magnet 1310 may be disposed below the coil 1230.

[0534] For example, the first magnet unit 1310A may be arranged to correspond to, face to, or overlap with the first coil unit 1230A in the optical axis direction, and the second magnet unit 1310B may be arranged to correspond to, face to, or overlap with the second coil unit 1230B in the optical axis direction.

[0535] For example, the first magnet unit 1310A and the second magnet unit 1310B may be arranged so as to be offset in the second direction or the third direction. For example, when viewed from above or in the optical axis direction, the first magnet unit 1310A and the second magnet unit 1310B may be arranged in the housing 1210 so as not to overlap with each other in the second direction or the third direction. For example, the first magnet unit 1310A and the second magnet unit 1310B may be arranged in the lower part 1042 of the housing 1210 so as not to overlap with each other in the second direction or the third direction.

[0536] In another embodiment, the magnet 1310 may be disposed in the holder 1140, and the coil 1230 may be disposed in the housing 1210. For example, the positions of the magnet 1310 and the coil 1230 may be reversed in Fig. 18. Here, the camera device 1200 may include a separate conductive part, such as a circuit board, a circuit member, or a conductive member, that electrically connects the second coil 1230 and the circuit board 1800.

[0537] Each of the first magnet unit 1310A and the second magnet unit 1310B may be a two-pole magnet including one north pole and one south pole. For example, the first magnet unit 1310A and the second magnet unit 1310B may be a magnet divided or arranged into north and south poles in the optical axis direction. For example, the north pole (or south pole) of each of the first magnet unit 1310A and the second magnet unit 1310B may be located above the south pole (or north pole).

[0538] For example, a first surface of the magnet 1310 facing or opposite the coil 1230 in the optical axis direction may be a south pole (or a north pole), and a second surface of the magnet 1310 opposite the first surface may be a north pole (or a south pole).

[0539] In another embodiment, each of the first magnet unit 1310A and the second magnet unit 1310B may be a magnet divided or arranged into one north pole and one south pole in a direction perpendicular to the optical axis direction. In yet another embodiment, each of the first magnet unit 1310A and the second magnet unit 1310B may be a magnet including two north poles and two south poles. An electromagnetic force may be generated between the first and second magnet units 1310A, 1310B and the first and second coil units 1230A, 1230B, and the generated electromagnetic force may cause the OIS vibration unit to tilt in the X-axis or Y-axis.

[0540] The housing 1210 may include a receiving portion 1049A for receiving the magnet 1031. The receiving portion 1049A may be disposed in or formed in the lower portion 1042 of the housing 1210. The receiving portion 1049A may be disposed in or formed on an upper surface of the lower portion 1042 of the housing 1210. For example, the receiving portion 1049A may be a groove recessed from the upper surface of the lower portion 1042 of the housing 1210. The receiving portion 1049A may have a shape corresponding to the magnet 1031, such as a square or circle. For example, the receiving portion 1049A of the housing 1210 may correspond to, face, or overlap with the receiving portion 1028A of the sensor base 1270 in the optical axis direction.

[0541] 25b, the housing 1210 may include a seat 1069 for positioning or receiving at least a portion of the moving plate 1060. For example, the seat 1069 may be a groove recessed from the upper surface of the housing 1210 or the upper surface of the lower portion 1042.

[0542] For example, the seat 1069 may have a shape that corresponds to or matches the shape of the moving plate 1060. For example, the seat 1069 may include a bottom surface 1069A that has a step with respect to the upper surface of the lower portion 1042 of the housing 1210 in the optical axis direction, and a side surface 1069B that connects the bottom surface 1069A and the upper surface of the lower portion 1042. For example, the bottom surface 1069A of the seat 1069 may be located lower than the upper surface of the lower portion 1042 of the housing 1210.

[0543] 19a and 19b, a seat 1069 for inserting or positioning at least a portion of the moving plate 1060 is formed on the upper surface of the lower portion 1042 of the housing 1210, and the lower portion 1042 of the housing 1210 may include a partition (or guide portion) 1272 disposed around the moving plate 1060. The moving plate 1060 may be spaced apart from the partition 1272 of the housing 1210, and the partition 1272 may be disposed to surround the moving plate 1060. The partition 1272 of the housing 1210 may prevent the moving plate 1060 from detaching or falling off the housing 1210.

[0544] The housing 1210 may include a protrusion (or projection) 1049 protruding from the lower portion 1042. For example, the protrusion 1049 may protrude from an upper surface of the lower portion 1042 of the housing 1210. For example, the protrusion 1049 may protrude from a bottom surface 1069A of a seat 1069 of the housing 1210. For example, the protrusion length of the protrusion 1049 of the housing 1210 may be greater than the depth of the seat 1069 of the housing 1210. For example, the protrusion length of the protrusion 1049 may be the distance (or shortest distance) from the bottom surface 1069A of the seat 1069 to the lower surface (or lowest end) of the protrusion 1049. Furthermore, the depth of the seat 1069 may be the distance (or shortest distance) from the upper surface of the lower portion 1042 of the housing 1210 to the bottom surface 1069A of the seat 1069. In other embodiments, for example, the protrusion length of the protrusion 1049 may be less than or equal to the depth of the seat 1069. For example, the protrusion 1049 may have a shape that corresponds to or matches the opening 1060A of the moving plate 1060.

[0545] For example, the protrusion 1049 of the housing 1210 may correspond to, face, or overlap with the opening 1060A of the moving plate 1060 in the optical axis direction. For example, at least a portion of the protrusion 1049 of the housing 1210 may be disposed within the opening 1060A of the moving plate 1060.

[0546] For example, the receiving portion 1049A may be disposed or formed in the protruding portion 1049 of the housing 1210. For example, the receiving portion 1049A may be a groove recessed from the upper surface of the protruding portion 1049 of the housing 1210.

[0547] For example, the protrusion 1049 can be disposed between the grooves 1055A, 1055B of the housing 1210. For example, the protrusion 1049 can be disposed between the protrusions 1066A, 1066B of the moving plate 1060. For example, the protrusion 1049 (or the magnet 1031) can overlap the protrusions 1066A, 1066B of the moving plate 1060 in a direction perpendicular to the optical axis, e.g., in a third direction.

[0548] For example, at least a portion of the first magnet unit 1310A may correspond to, face, or overlap with the moving plate 1060 in a direction parallel to the first axis, and at least a portion of the second magnet unit 1310B may correspond to, face, or overlap with the moving plate 1060 in a direction parallel to the second axis.

[0549] The housing 1210 may include grooves 1055 in which at least a portion of the protrusions 1066 of the moving plate 1060 are disposed or for accommodating at least a portion of the protrusions 1066. The grooves 1055 of the housing 1210 may be formed in an upper surface of the lower portion 1042 of the housing 1210. For example, the grooves 1055 may be recessed from the upper surface of the lower portion 1042 of the housing 1210. For example, the grooves 1055 may be formed in a bottom surface 1069A of the seating portion 1069 of the housing 1210. For example, the grooves 1055 may be recessed from the bottom surface 1069A of the seating portion 1069 of the housing 1210. The number of grooves 1055 of the housing 1210 may be the same as the number of protrusions 1066 of the moving plate 1060.

[0550] For example, the groove 1055 may include two grooves 1055A and 1055B spaced apart from each other. For example, the two grooves 1055A and 1055B may be spaced apart from each other in the Y-axis direction. For example, the direction in which the two grooves 1055A and 1055B of the housing 1210 are spaced apart from each other may intersect or be perpendicular to the direction in which the two grooves 1029A and 1029B of the sensor base 1270 are spaced apart from each other. For example, the receiving portion 1049A may be located between the two grooves 1055A and 1055B of the housing 1210.

[0551] The groove 1055 of the housing 1210 may contact the protrusion 1066 of the moving plate 1060 at at least one point. For example, the groove 1055 may include a bottom surface and at least one side surface connected to the bottom surface. At least one side surface of the groove 1055 may be an inclined surface. For example, the groove 1055 may include a bottom surface and multiple inclined surfaces. The shapes of the inclined surfaces of the groove 1055 may be the same as each other. In other embodiments, at least one of the inclined surfaces of the groove 1055 may have a different shape from the rest.

[0552] The housing 1210 may include a protrusion 1215 that protrudes in a direction perpendicular to the optical axis. For example, the protrusion 1215 may protrude from a side of the housing 1210.

[0553] For example, the protrusion 1215 may protrude from the outer surface of the fourth side 1071D of the housing 1210. For example, the protrusion 1215 may have a form in which at least a portion of the fourth side 1071D protrudes in a direction parallel to a line perpendicular to the optical axis while passing through the optical axis. For example, the protrusion 1215 may include a groove (or cavity) 1016A in which at least a portion of the fourth substrate 1804 is disposed or accommodated. For example, the groove 1016A of the protrusion 1215 may include an opening that is open at the top.

[0554] 25a, the groove 1016A of the protrusion 1215 may have coupling grooves 1215A and 1215B formed therein for the movement suppressing portion 1080 to be inserted into, coupled to, or fixed thereto. For example, the coupling grooves 1215A and 1215B may be formed on two inner surfaces of the groove 1016A of the protrusion 1215 that face each other. For example, the coupling grooves 1215A and 1215B may extend in the optical axis direction. For example, the coupling grooves 1215A and 1215B may include openings that open on the upper surface of the protrusion 1215 so that the movement suppressing portion 1080 can be easily inserted into or coupled to the groove 1016A from above.

[0555] The maximum length of the protrusion 1215 in the optical axis direction may be smaller than the maximum length of the housing 1210 in the optical axis direction. With this configuration, it is possible to easily ensure a space for the circuit board 1800 to extend outward, thereby realizing a compact camera device.

[0556] Camera device 1200 may include a movement suppressing portion 1080 coupled to at least a portion of housing 1210. Movement suppressing portion 1080 may suppress movement or motion of at least a portion of fourth substrate 1804, thereby suppressing deformation of the shape of at least a portion of fourth substrate 1804.

[0557] 22c, 23, and 26, the fourth substrate 1804 of the circuit board 1800 may include a first portion (or "first region") 1804A connected to the first substrate 1801, a second portion 1804B connected to the first portion 1804A and bent from the first portion 1804A, and a third portion 1804C connected to the second portion 1804B and bent from the second portion 1804B. In other embodiments, either the first portion 1804A or the second portion 1804B may be omitted.

[0558] For example, first portion 1804A may extend in a direction parallel to first substrate 1801. For example, second portion 1804B may be bent from first portion 1804A and extend upward from first portion 1804A. For example, third portion 1804C may extend from second portion 1804B in a direction opposite to first portion 1804A.

[0559] For example, fourth substrate 1804 may include a first bent portion 1804D connecting first portion 1804A and second portion 1804B. Fourth substrate 1804 may also include a second bent portion 1804E connecting second portion 1804B and third portion 1804C. First bent portion 1804D and second bent portion 1804E may be angular, for example, first portion 1804A and second portion 1804B may be perpendicular. In other embodiments, first bent portion 1804D and second bent portion 1804E may be rounded. In other embodiments, the interior angle between first portion 1804A and second portion 1804B may be acute or obtuse.

[0560] The first bent portion 1804D and the second bent portion 1804E can prevent an increase in the length in a direction perpendicular to the optical axis direction of the camera device 1200. Furthermore, since the first bent portion 1804D and the second bent portion 1804E are located between the upper surface of the camera device 1200 (e.g., the upper surface of the cover member 1300) and the lower surface of the camera device 1200 (e.g., the lower surface of the housing 1210), an increase in the length of the camera device 1200 in the optical axis direction can be prevented, and the camera device can be made more compact.

[0561] For example, the third portion 1804C may be in the form of a plate or a plane perpendicular to the optical axis. For example, the third portion 1804C may include a serpentine or wave shape. For example, the third portion 1804C may include at least one folded or curved region. For example, the folded or curved region of the third portion 1804C 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 1804C may extend in a direction perpendicular to the optical axis. For example, when viewed from above, the third portion 1804C may include a region having a U-shape or a V-shape.

[0562] For example, third portion 1804C can be spaced apart from housing 1210. For example, third portion 1804C can be spaced apart from protrusion 1215 of housing 1210. In other embodiments, for example, at least a portion of third portion 1804C can contact protrusion 1215 of housing 1210.

[0563] At least a portion of the second portion 1804B of the fourth substrate 1804 may be disposed within the protrusion 1215 of the housing 1210. At least a portion of the second portion 1804B of the fourth substrate 1804 may be disposed within the groove 1016A of the protrusion 1215 of the housing 1210. For example, at least a portion of the first portion 1804A of the fourth substrate 1804 may be disposed within the groove 1016A of the protrusion 1215. The third portion 1804C of the fourth substrate 1804 may be located outside the protrusion 1215 of the housing 1210. For example, the third portion 1804C of the fourth substrate 1804 may be located above the protrusion 1215 of the housing 1210. A lower surface of the third portion 1804C of the fourth substrate 1804 may be located above an upper surface of the protrusion 1215 of the housing 1210.

[0564] 22a, the sensor base 1270 may include a groove 1273 formed at a location where the fourth substrate 1804 and the first substrate 1801 meet or are connected, for example, at a position corresponding to the first portion 1804A of the fourth substrate 1804. The groove 1273 may be disposed adjacent to or in contact with the outer surface of the fourth side 1071D of the sensor base 1270 on which the fourth substrate 1804 is disposed. The groove 1273 may serve to prevent the first portion 1804A of the fourth substrate 1804 from being damaged due to friction with the sensor base 1270.

[0565] The connector 1805 may be coupled or connected to another connector outside the camera device 1200 or an external device. The connector 1805, which is coupled to another external connector, may correspond to a fixed portion that does not move when the OIS is operated. The third portion 1804C of the fourth substrate 1804 includes at least one bent or curved region, and thus may be able to elastically support the camera device 1200 or the OIS operating unit and absorb external shocks. That is, the third portion 1804C of the fourth substrate 1804 may function as a spring that absorbs shocks. Furthermore, because the third portion 1804C of the fourth substrate 1804 may be able to elastically support the OIS operating unit 1100, the driving force or driving power required when the OIS is operated may be reduced.

[0566] The camera apparatus 1200 may include a reinforcing member 1070 disposed on, coupled to, or attached to at least a portion of the fourth substrate 1804. The reinforcing member 1070 may be disposed on, coupled to, or attached to any one of the first portion 1804A and the second portion 1804B of the fourth substrate 1804. For example, the reinforcing member 1070 may be disposed on, coupled to, or attached to at least a portion of the first portion 1804A and at least a portion of the second portion 1804B of the fourth substrate 1804.

[0567] 26 , for example, the reinforcing member 1070 may be disposed on, coupled to, or attached to the lower surface of the first portion 1804A and the lower surface of the second portion 1804B of the fourth substrate 1804. For example, the reinforcing member 1070 may include a first region 1070A disposed on, coupled to, or attached to the first portion 1804A, and a second region 1070B disposed on, coupled to, or attached to the second portion 1804B. The second region 1070B may be bent upward from the first region 1070A. For example, a bent portion may be formed between the first region 1070A and the second region 1070B.

[0568] For example, the area of ​​the second region 1070B may be larger than the area of ​​the first region 1070A. In other embodiments, the two may be the same, or the area of ​​the former 1070B may be smaller than the area of ​​the latter 1070A.

[0569] For example, the reinforcing member 1070 can be spaced apart from the third portion 1804C of the fourth substrate 1804. For example, the second region 1070B of the reinforcing member 1070 can be spaced apart from the third portion 1804C of the fourth substrate 1804. In other embodiments, at least a portion of the second region 1070B of the reinforcing member 1070 can contact the third portion 1804C of the fourth substrate 1804.

[0570] In other embodiments, the reinforcing member 1070 may be disposed on, coupled to, or attached to an upper surface of the first portion 1804A and an upper surface of the second portion 1804B of the fourth substrate 1804. For example, in other embodiments, the reinforcing member 1070 may include a first region disposed on the upper surface of the first portion 1804A of the fourth substrate 1804 and a second region disposed on the upper surface of the second portion 1804B.

[0571] In yet another embodiment, the reinforcing member 1070 may be disposed on, coupled to, or attached to at least a portion of the second portion 1804B and at least a portion of the third portion 1804C of the fourth substrate 1804. For example, in another embodiment, the reinforcing member 1070 may be disposed on, coupled to, or attached to the second portion 1804B and the third portion 1804C of the fourth substrate 1804. For example, the reinforcing member 1070 may include a first region disposed on, coupled to, or attached to the second portion 1804B of the fourth substrate 1804 and a second region disposed on, coupled to, or attached to the third portion 1804C, and a bent portion may be formed between the first and second regions. The first region of the reinforcing member 1070 may be disposed on a lower surface (or an upper surface) of the second portion 1804B, and the second region of the reinforcing member 1070 may be disposed on a lower surface (or an upper surface) of the third portion 1804C.

[0572] The reinforcing member 1070 may prevent the fourth substrate 1804 from being damaged, deformed, or broken due to an impact or external force. In addition, the reinforcing member 1070 may function to prevent the fourth substrate 1804 from being deformed or restored to its original shape when the fourth substrate 1804 is pressed by tilting of the OIS operating unit 1100. For example, the reinforcing member 1070 may include at least one of a metal material or an injection molding material.

[0573] For example, the reinforcing member 1070 may be disposed within the groove 1016A of the protrusion 1215 of the housing 1210. For example, the reinforcing member 1070 may be in at least partial contact with the groove 1016A of the protrusion 1215 of the housing 1210. For example, the reinforcing member 1070 may not be coupled to the housing 1210 (e.g., the protrusion 1215). In other embodiments, for example, the reinforcing member 1070 may be coupled to the housing 1210 (e.g., the protrusion 1215) with an adhesive.

[0574] 16, 25a, and 25b, the movement suppressing portion 1080 may be coupled to the protrusion 1215 of the housing 1210. For example, the movement suppressing portion 1080 may be coupled to the coupling grooves 1215A and 1215B of the protrusion 1215 of the housing 1210.

[0575] 18 , at least a portion of second portion 1804B of fourth substrate 1804 can be disposed between movement suppressing portion 1080 and the inner surface of protrusion 1215 of housing 1210. For example, at least a portion of reinforcing member 1070 can be disposed between movement suppressing portion 1080 and the inner surface of protrusion 1215 of housing 1210.

[0576] The movement suppressing portion 1080 may be spaced apart from the circuit board 1800 in the second direction (X-axis direction) or the third direction (Y-axis direction). For example, the movement suppressing portion 1080 may be spaced apart from the circuit board 1800 in the optical axis direction or in a direction perpendicular to the optical axis direction. That is, the movement suppressing portion 1080 may serve to maintain the shape of the bent portions 1804D and 1804E of the fourth substrate 1804, which is a flexible substrate. For example, the movement suppressing portion 1080 may be an injection-molded product made of a non-magnetic material or resin. In another embodiment, the movement suppressing portion 1080 may contact at least a portion of the fourth substrate 1804 of the circuit board 1800.

[0577] The movement suppressing portion 1080 can restrict movement or motion of at least a portion of the second portion 1804B of the fourth substrate 1804 arranged in the groove 1016A of the protrusion 1215, and can suppress or prevent the second portion 1804B from escaping out of the groove 1016A of the protrusion 1215. Therefore, when driving the OIS, it is possible to suppress or prevent the OIS operating portion from being affected by the restoring force of the fourth substrate 1804, allowing for accurate OIS driving and improving the reliability of OIS driving. The movement suppressing portion 1080 can also be expressed as a "clamp."

[0578] The cover member 1300 may form an accommodation space together with the housing 1210, and an OIS operating unit may be disposed in the accommodation space. For example, the cover member 1300 may be box-shaped with an open bottom. For example, the cover member 1300 may include an upper plate 1301 and a side plate 1302 connected to the upper plate 1301.

[0579] The bottom end of the side plate 1302 of the cover member 1300 can be coupled to the housing 1210. 1301 The shape of the cover member 1300 may be polygonal (e.g., square or octagonal) or circular. 1301 The cover member 1300 may include an opening 1303 for exposing a lens (not shown) to external light. The opening 1303 may be a through-hole formed in the upper plate 1301 of the cover member 1300 in the optical axis direction. For example, the side plate of the cover member 1300 may include a plurality of side plates. The cover member 1300 may be made of a non-magnetic material. In another embodiment, the cover member 1300 may be made of a magnetic material. For example, the cover member 1300 may be made of an injection-molded material such as resin, or may be made of a metal material.

[0580] 16 and 17a, the cover member 1300 may include an opening 1304 disposed or formed in the side plate 1302 to avoid spatial interference with the protrusion 1215 of the housing 1210. For example, the protrusion 1215 of the housing 1210 may pass through the opening 1304 of the cover member 1300 and protrude from the side plate 1302 of the cover member 1300.

[0581] The cover member 1300 is disposed over the opening 1304 and may include a protrusion 1305 protruding from the side plate 1302. For example, the protrusion 1305 may be plate-shaped. For example, the protrusion 1305 of the cover member 1300 may be disposed over the protrusion 1215 of the housing 1210. For example, the protrusion 1305 may be disposed above the groove 1016A of the protrusion 1215 of the housing 1210. For example, the protrusion 1305 may be disposed above the movement suppressing portion 1080. For example, the protrusion 1305 may overlap the movement suppressing portion 1080 in the optical axis direction. Furthermore, for example, the protrusion 1305 may overlap the first portion 1804A of the fourth substrate 1804 in the optical axis direction. The protrusion 1305 may suppress or prevent the movement suppressing portion 1080 from separating and may protect the movement suppressing portion 1080 and the fourth substrate 1804 from impact.

[0582] The cover member 1300 may include a protrusion (not shown) protruding from the upper plate 1301. Here, the protrusion of the cover member 1300 may protrude from the inner surface of the upper plate 1301 of the cover member 1300 toward the bobbin 1110 or the rolling member 1021. For example, the protrusion of the cover member 1300 may face or overlap the accommodating portion 1116 of the bobbin 1110 in the optical axis direction. At least a portion of the protrusion of the cover member 1300 may be inserted or disposed within the accommodating portion 1116 of the bobbin 1110. The protrusion of the cover member 1300 may be disposed on the rolling member 1021. For example, the cover member 1300 may include a first protrusion (not shown) corresponding to, facing, or overlapping the first rolling member 1021A or the first accommodating portion 1116A of the bobbin 1110. For example, the cover member 1300 may include a second protrusion (not shown) that corresponds to, faces, or overlaps with the second rolling member 1021B or the second receiving portion 1116B of the bobbin 1110. For example, the protrusion of the cover member 1300 may include a groove that is recessed from the upper surface of the upper plate 1301 of the cover member 330. In other embodiments, the protrusion of the cover member 1300 may not include a groove. By providing the protrusion on the cover member 1300, the embodiment can prevent the rolling member 1021 from separating from the receiving portion 1116 of the bobbin 1110. In addition, the protrusion of the cover member 1300 may function as a stopper that prevents the bobbin 1110 from moving further upward within a limited range.

[0583] Next, the support portion will be described.

[0584] The support portion is disposed between the sensor base 1270 and the housing 1210 and can support the sensor base 1270 relative to the housing 1210. The support portion can include a moving plate 1060 disposed between the moving portion (e.g., the sensor base 1270) and the fixed portion (e.g., the housing 1210).

[0585] Moving plate 1060 may also be referred to interchangeably as a "drive plate," "mover," "mover plate," "drive plate," "plate," "rotating plate," "tilting plate," "moving plate," or "support plate."

[0586] The moving plate 1060 can tilt about the first axis or the second axis or rotate by a preset angle. For example, the moving plate 1060 can be disposed between the lower part (or lower surface) of the sensor base 1270 and the lower part 1042 of the housing 1210. For example, at least a portion of the moving plate 1060 can be disposed within the seat 1069 of the housing 1210. Because the moving plate 1060 is disposed within the seat 1069 of the housing 1210, the length or height of the camera device 1200 in the optical axis direction can be reduced.

[0587] 19b, 24a, and 27, the moving plate 1060 may be plate-shaped. For example, the length of the moving plate 1060 in the horizontal direction perpendicular to the optical axis (e.g., the lateral or vertical direction) may be greater than the length of the moving plate 1060 in the optical axis direction.

[0588] 24a and 24b, the moving plate 1060 may include a first protrusion 1065 that couples with or is in contact with the sensor base 1270, and a second protrusion 1066 that couples with or is in contact with the housing 1210. The first protrusion 1065 may be disposed on a first surface (e.g., an upper surface) 1006A of the moving plate 1060, and the second protrusion 1066 may be disposed on a second surface (or lower surface) 1006B that is opposite the first surface 1006A of the moving plate 1060. For example, the first protrusion 1065 may protrude from the first surface 1006A (e.g., an upper surface) of the moving plate 1060, and the second protrusion 1066 may protrude from the second surface 1006B (e.g., a lower surface) of the moving plate 1060.

[0589] The first protrusion 1065 can be expressed interchangeably as an “upper protrusion (or front protrusion)” or a “first protrusion,” and the second protrusion 1066 can be expressed interchangeably as a “lower protrusion (or rear protrusion)” or a “second protrusion.” The number of each of the first protrusions 1065 and the second protrusions 1066 can be one, two, or three or more.

[0590] At least a portion of the first protrusion 1065 may be disposed in the groove 1029 of the sensor base 1270. The first protrusion 1065 may include at least two protrusions 1065A, 1065B. For example, the at least two protrusions 1065A, 1065B may be disposed spaced apart in the second direction. Each of the two protrusions 1065A, 1065B may be inserted into a corresponding one of the first and second grooves 1029A, 1029B of the sensor base 1270.

[0591] At least a portion of the second protrusion 1066 may be disposed within the groove 1055 of the housing 1210. The second protrusion 1066 may include at least two protrusions 1066A, 1066B. For example, the two protrusions 1066A, 1066B may be spaced apart in the third direction. Each of the two protrusions 1066A, 1066B may be inserted into a corresponding one of the first and second grooves 1055A, 1055B of the housing 1210.

[0592] In other embodiments, the two protrusions 1065A, 1065B may be spaced apart in the third direction, the first and second grooves 1029A, 1029B of the sensor base 1270 may be spaced apart in the third direction, the two protrusions 1066A, 1066B may be spaced apart in the second direction, and the first and second grooves 1055A, 1055B of the housing 1210 may be spaced apart in the second direction.

[0593] For example, each of the first protrusion 1065 and the second protrusion 1066 may have a curved, hemispherical, dome, or polyhedral shape, but is not limited thereto. For example, the shape of the first protrusion 1065 when viewed from the front or top and the shape of the second protrusion 1066 when viewed from the rear or bottom may be circular, elliptical, or polygonal.

[0594] Moving plate 1060 may include opening 1060A that corresponds to, faces, or overlaps with magnet 1031 and / or magnetic material 1032. For example, opening 1060A may correspond to, faces, or overlap with protrusion 1049 of housing 1210. Opening 1060A can reduce the weight (or mass) of moving plate 1060, thereby making camera device 1200 lighter.

[0595] For example, opening 1060A of moving plate 1060 may be positioned at a position corresponding to protrusion 1049 to avoid spatial interference with protrusion 1049 of housing 1210. Also, opening 1060A of moving plate 1060 may be formed to avoid spatial interference with magnet 1031 and protrusion 1049 of housing 1210.

[0596] For example, the opening 1060A of the moving plate 1060 may be a through-hole. For example, the opening 1060A may penetrate the moving plate 1060 in the first direction (Z-axis direction) or the optical axis direction. For example, at least a portion of the opening 1060A of the moving plate 1060 may have a shape corresponding to the protrusion 1049 of the housing 1210. For example, the opening 1060A may have a circular, elliptical, or polygonal shape, such as a square.

[0597] For example, the horizontal length of opening 1060A of moving plate 1060 may be greater than the horizontal length of protrusion 1049 of housing 1210. In other embodiments, the horizontal length of opening 1060A may be the same as the horizontal length of protrusion 1049 of housing 1210. The vertical length of opening 1060A may be greater than the vertical length of protrusion 1049 of housing 1210. In other embodiments, the vertical length of opening 1060A may be the same as the vertical length of protrusion 1049 of housing 1210.

[0598] At least a portion of the protrusion 1049 of the housing 1210 can be disposed within the opening 1060A of the moving plate 1060. For example, the protrusion 1049 of the housing 1210 can overlap with the opening 1060A of the moving plate 1060 in the optical axis direction. Also, for example, the protrusion 1049 of the housing 1210 can overlap with the moving plate 1060 in a direction perpendicular to the optical axis direction. Thus, the length or height of the camera device 1200 in the optical axis direction can be reduced.

[0599] For example, at least a portion of the opening 1060A may be disposed between the two protrusions 1065A and 1065B of the first protrusion 1065 of the moving plate 1060. Also, at least a portion of the opening 1060A may be disposed between the protrusions 1066A and 1066B of the second protrusion 1066 of the moving plate 1060.

[0600] For example, the moving plate 1060 may be an injection molded part. For example, the moving plate 1060 may be made of a plastic, resin, or ceramic material. In other embodiments, the moving plate 1060 may include a metal material, such as stainless steel. The moving plate 1060 may also be a non-magnetic material. In other embodiments, the moving plate 1060 may be a magnetic material.

[0601] The protrusions 1065A and 1065B of the first protrusion 1065 and the protrusions 1066A and 1066B of the second protrusion 1066 may be arranged side by side in directions that intersect or are perpendicular to each other. The first protrusion 1065 of the moving plate 1060 allows the OIS operating unit to rotate, pivot, or tilt in either the second direction or the third direction. The second protrusion 1066 of the moving plate 1060 allows the OIS operating unit to rotate, pivot, or tilt in the other direction of the second direction or the third direction.

[0602] In another embodiment, the moving plate 1060 may omit either the first protrusion 1065 or the second protrusion 1066, and a rolling member or a ball member may be disposed in place of the omitted protrusion.

[0603] For example, the moving plate 1060 may include a first groove formed on the upper surface of the moving plate 1060 instead of the first protrusion 1065, and a second groove formed on the lower surface of the moving plate 1060 instead of the second protrusion 1066, and the support may include a first rolling member (or a first ball member) disposed between the groove 1029 of the sensor base 1270 and the first groove of the moving plate 1060, and a second rolling member (or a second ball member) disposed between the second groove of the moving plate 1060 and the groove 1055 of the housing 1210. For example, the first groove of the moving plate 1060 may include two first grooves, the second groove of the moving plate 1060 may include two second grooves, the first rolling member may include two balls, and the second rolling member may include two balls. The description of the shape of the groove 1029 of the sensor base 1270 or the groove 1055 of the housing 1210 can be applied or analogously applied to the shape of the first groove and the second groove of the moving plate 1060 .

[0604] A groove 1055 may be disposed between the first protrusion 1066 of the moving plate 1060 and the groove 1029 of the sensor base 1270 or the second protrusion 1066 of the moving plate 1060 and the groove 1055 of the housing 1210 to reduce frictional forces and protect the moving plate 1060.

[0605] The first protrusion 1065 of the moving plate 1060 can slide within the groove 1029 of the sensor base 1270, and the second protrusion 1066 can slide within the groove 1055 of the housing 1210. This reduces the frictional force between the moving plate 1060 and the sensor base 1270 and / or the frictional force between the moving plate 1060 and the housing 1210, thereby reducing the current consumption or power consumption for driving the OIS.

[0606] 19d and 27, the rolling member 1021 may not overlap with the moving plate 1060 in the optical axis direction. For example, as shown in Fig. 19c, the rolling member 1021 may not overlap with the moving plate 1060 in the direction perpendicular to the optical axis.

[0607] For example, the direction of separation between the first rolling member 1021A and the second rolling member 1021B may be perpendicular to or intersect with the direction of separation between the protrusions 1065A and 1065B of the moving plate 1060. In other embodiments, the former and the latter may be parallel.

[0608] For example, the direction of separation between the first rolling member 1021A and the second rolling member 1021B may be parallel to or intersect with the direction of separation between the protrusions 1066A and 1066B of the moving plate 1060. In other embodiments, the former and the latter may be perpendicular.

[0609] For example, when viewed from above, the separation distance between protrusions 1065A and 1065B of moving plate 1060 may be smaller than the separation distance between first rolling member 1021A and second rolling member 1021B. In other embodiments, the separation distance between protrusions 1065A and 1065B of moving plate 1060 may be the same as or larger than the separation distance between first rolling member 1021A and second rolling member 1021B.

[0610] For example, when viewed from above, the distance between protrusions 1066A and 1066B of moving plate 1060 may be smaller than the distance between first rolling member 1021A and second rolling member 1021B. In other embodiments, the distance between protrusions 1066A and 1066B of moving plate 1060 may be the same as or larger than the distance between first rolling member 1021A and second rolling member 1021B.

[0611] The support portion may include a magnetic body 1032 disposed in the OIS operating portion (e.g., sensor base 1270) and a magnet 1031 disposed in the fixed portion (e.g., housing 1210). In another embodiment, the magnetic body 1032 may be disposed in the fixed portion (e.g., housing 1210), and the magnet 1031 may be disposed in the OIS operating portion (e.g., sensor base 1270). The magnet 1031 may be referred to interchangeably as a "magnetic body," a "yoke," or a "holding magnet."

[0612] For example, the magnet 1031 can be disposed in or coupled to the groove 1049A of the protrusion 1049 of the housing 1210. At least a portion of the magnet 1031 can be disposed in the opening 1060A of the moving plate 1060. For example, the magnet 1031 can face or overlap the opening 1060A of the moving plate 1060 in the optical axis direction. For example, the magnet 1031 does not have to overlap with the moving plate 1060 in the optical axis direction. Also, for example, at least a portion of the magnet 1031 can overlap with the moving plate 1060 in a direction perpendicular to the optical axis.

[0613] The magnet 1031 may correspond to, face, or overlap with the magnetic material 1032 in the optical axis direction. The magnet 1031 may be a two-pole magnet divided or arranged into a north pole and a south pole. For example, the magnet 1031 may be a two-pole magnet divided or arranged into a north pole and a south pole in the optical axis direction. In another embodiment, the magnet 1031 may be a two-pole magnet divided or arranged into a north pole and a south pole in a direction perpendicular to the optical axis direction. In yet another embodiment, the magnet 1031 may be a four-pole magnet including two north poles and two south poles.

[0614] The magnetic material 1032 may be disposed above the magnet 1031. The magnetic material 1032 may be disposed in the groove 1028A of the sensor base 1270. For example, the magnetic material 1032 may be coupled with the groove 1028A of the sensor base 1270.

[0615] The magnetic body 1032 may overlap the opening 1060A of the moving plate 1060 in the optical axis direction. The magnetic body 1032 may not overlap the moving plate 1060 in the optical axis direction. The magnetic body 1032 may not overlap the moving plate 1060 in a direction perpendicular to the optical axis. In other embodiments, the magnetic body 1032 may overlap the moving plate 1060 in a direction perpendicular to the optical axis.

[0616] When viewed from above, the area of ​​opening 1060A of moving plate 1060 may be larger than the area of ​​the upper surface (or lower surface) of magnet 1031. Also, when viewed from above, the area of ​​opening 1060A of moving plate 1060 may be larger than the area of ​​the upper surface (or lower surface) of magnetic body 1032.

[0617] For example, an attractive force in the optical axis direction (or first direction) may act between the magnetic body 1032 and the magnet 1031. The magnetic body 1032 may be made of a magnetic material. For example, the magnetic body 1032 may be made of a magnetic metal material. Alternatively, for example, the magnetic body 1032 may be made of a magnetic metal material. Alternatively, for example, the magnetic body 1032 may be a magnet. The magnetic body 1032 may also be expressed as a "yoke."

[0618] Due to the attractive force between the magnetic body 1032 and the magnet 1031, the sensor base 1270 and the housing 1210 can press the moving plate 1060, and the first protrusion 1065 and the second protrusion 1066 of the moving plate 1060 can be closely attached to the sensor base 1270 and / or the housing 1210. Due to the attractive force between the magnetic body 1032 and the magnet 1031, the moving plate 1060 can stably support the OIS operating part with respect to the fixed part, thereby enabling stable OIS operation.

[0619] Furthermore, since at least a portion of the magnet 1031 is positioned within the opening 1060A of the moving plate 1060, the separation distance between the magnet 1031 and the magnetic body 1032 can be reduced, thereby increasing the attractive force between the magnet 1031 and the magnetic body 1032, and enabling the OIS operating part to be stably supported on the fixed part.

[0620] In addition, since the magnet 1031 is positioned in the central region of the lower part 1042 of the housing 1210 and the magnetic material 1032 is positioned in the center of the underside of the sensor base 1270, the attractive force between the magnet 1031 and the magnetic material 1032 can be concentrated at the center of the sensor base 1270 and the center of the housing 1210, thereby enabling efficient and stable support of the OIS operating part.

[0621] In another embodiment, the protrusion 1049 of the housing 1210 may be omitted, the magnet 1031 may be disposed on the upper surface of the lower portion 1042 of the housing 1210, the sensor base 1270 may include a protrusion protruding from the lower surface of the sensor base 1270 to correspond to, face, or overlap with the opening 1060A of the moving plate 1060, and the magnetic member 1032 may be disposed on the protrusion of the sensor base 1270. Here, the seat 1069 of the housing 1210 may be omitted, and a seat corresponding to or identical to the seat 1069 of the housing 1210 may be formed on the lower surface of the sensor base 1270, the moving plate 1060 may be disposed within the seat of the sensor base 1270, the protrusion protrudes from the bottom surface of the seat of the sensor base 1270, a groove in which the magnetic member 1032 is disposed may be formed in the protrusion of the sensor base 1270, and a groove in which the magnet 1031 is disposed may be formed in the lower portion 1042 of the housing 1210. In yet another embodiment, at least a portion of the protrusion of the sensor base 1270 may be disposed within the opening 1060A of the moving plate 1060 and overlap with the moving plate 1060 in a direction perpendicular to the optical axis. In yet another embodiment, the magnet 1031 may be disposed on the protrusion (or the groove of the protrusion) of the sensor base 1270, and the magnetic material 1032 may be disposed on the lower part 1042 (or the groove of the lower part 1042) of the housing 1210.

[0622] In still another embodiment, the moving plate 1060 can be omitted, and the support unit can include rolling members, for example, ball members, disposed between the sensor base 1270 and the housing 1210. Here, the rolling members can include two first ball members disposed in a direction parallel to a first axis and two second ball members disposed in a direction parallel to a second axis, and the OIS operating unit can tilt around the first ball members as an axis or rotate by a predetermined angle, and can tilt around the second ball members as an axis or rotate by a predetermined angle, thereby performing an image stabilization operation.

[0623] 27 and 28a, the first magnet unit 1310A may overlap the protrusions 1065A and 1065B of the moving plate 1060 in a direction in which the protrusions 1065A and 1065B face each other. Also, the second magnet unit 1310B may overlap the protrusions 1066A and 1066B of the moving plate 1060 in a direction in which the protrusions 1066A and 1066B face each other.

[0624] 19b, the moving plate 1060 may overlap the magnet 1310 in a direction perpendicular to the optical axis. For example, the first magnet unit 1310A may overlap the moving plate 1060 in a second direction, and the second magnet unit 1310B may overlap the moving plate 1060 in a third direction.

[0625] For example, the magnet 1310 may be disposed below the image sensor 1810. For example, the magnet 1310 may be disposed below the filter 1610. The magnet 1310 may also be disposed below the magnetic material 1032. For example, the magnet 1310 may be located below the holder 1140. For example, the magnet 1310 may be disposed below the sensor base 1270. For example, the upper surface of the magnet 1310 may be located below the lower surface of the sensor base 1270. The upper surface of the magnet 1310 may be located below the lower surface of the holder 1140. The upper surface of the magnet 1310 may be located below the lower surface of the magnetic material 1032. For example, the magnet 1310 may be located below the rolling members 1021.

[0626] For example, the top surface of magnet 1310, e.g., the top surfaces of magnet units 1310A and 1310B, may be located lower than the top surface of magnet 1031. In other embodiments, the top surface of magnet 1310 may be located higher than the top surface of magnet 1031 or may be at the same height as the top surface of magnet 1031.

[0627] For example, the upper surface of magnet 1310, e.g., the upper surfaces of magnet units 1310A and 1310B, may be located lower than the lower surface of magnet 1031. In other embodiments, the upper surface of magnet 1310 may be located higher than the lower surface of magnet 1031 or may be at the same height as the lower surface of magnet 1031.

[0628] Referring to Figures 27 and 28a, the first length L1 of the first magnet unit 1310A in the second direction (x-axis direction) may be smaller than the second length L2 of the first magnet unit 1310A in the third direction (y-axis direction).

[0629] For example, first length L1 may be smaller than length M2 of moving plate 1060 in the second direction. For example, first length L1 may be larger than length M1 between the outer peripheral surface and inner peripheral surface of moving plate 1060 in the second direction. For example, M1 may be the shortest distance between the outer surface of moving plate 1060 and opening 1060A of moving plate 1060 in the second direction. In other embodiments, L1 may be the same as or smaller than M1.

[0630] For example, the first length L1 may be smaller than the length M5 in the second direction of the opening 1060A of the moving plate 1060. Also, for example, the first length L1 may be smaller than the length in the second direction of the protrusion 1049 of the housing 1210. In other embodiments, the first length L1 may be larger than or equal to the length in the second direction of the opening 1060A of the moving plate 1060.

[0631] For example, the second length L2 may be smaller than the length M4 of the moving plate 1060 in the third direction. In other embodiments, the second length L2 may be greater than or equal to the length M4 of the moving plate 1060 in the third direction.

[0632] For example, the second length L2 may be greater than the length M6 in the third direction of the opening 1060A of the moving plate 1060. For example, the second length L2 may be greater than the length M6 in the third direction of the protrusion 1049 of the housing 1210. In other embodiments, the second length L2 may be less than or equal to the length M6 in the third direction of the opening 1060A of the moving plate 1060.

[0633] Referring to Figures 27 and 28a, the third length L3 of the second magnet unit 1310B in the third direction (y-axis direction) may be smaller than the fourth length L4 of the second magnet unit 1310B in the second direction (x-axis direction).

[0634] For example, the third length L3 may be smaller than the length M4 of the moving plate 1060 in the third direction. For example, the third length L3 may be larger than the length M3 between the outer peripheral surface and the inner peripheral surface of the moving plate 1060 in the third direction. For example, M3 may be the shortest distance between the outer surface of the moving plate 1060 in the third direction and the opening 1060A of the moving plate 1060. In other embodiments, L3 may be the same as or smaller than M3.

[0635] For example, the third length L3 may be smaller than the length M6 in the third direction of the opening 1060A of the moving plate 1060. Also, for example, the third length L3 may be smaller than the length in the third direction of the protrusion 1049 of the housing 1210. In other embodiments, the third length L3 may be larger than or equal to the length in the third direction of the opening 1060A of the moving plate 1060.

[0636] For example, the fourth length L4 may be smaller than the length M2 of the moving plate 1060 in the second direction. In other embodiments, the fourth length L4 may be greater than or equal to the length M2 of the moving plate 1060 in the second direction.

[0637] For example, the fourth length L4 may be greater than the length M5 in the second direction of the opening 1060A of the moving plate 1060. For example, the fourth length L4 may be greater than the length in the second direction of the protrusion 1049 of the housing 1210. In other embodiments, the fourth length L4 may be less than or equal to the length in the second direction of the opening 1060A of the moving plate 1060.

[0638] For example, the third length L3 may be equal to the first length L1. In other embodiments, L3 may be less than or greater than L1. For example, the second length L2 may be equal to the fourth length L4. In other embodiments, L2 may be less than or greater than L4.

[0639] For example, the top surface of the magnet 1310 may be located below the top surface of the protrusion 1049 of the housing 1210. This is to ensure sufficient space to avoid spatial interference between the magnet 1310 and the bottom surface of the sensor base 1270.

[0640] In another embodiment, the top surface of the magnet 1310 may be positioned higher than the top surface of the protrusion 1049 of the housing 1210. In yet another embodiment, the top surfaces of the magnet 1310 and the protrusion 1049 of the housing 1210 may be flush with each other.

[0641] For example, the top surface of the magnet 1310 may be located below the highest point of the protrusion 1065 of the moving plate 1060 .

[0642] When viewed from above or along the optical axis, the protrusions 1065A, 1065B, the magnet 1031, and the first magnet unit 1310A may overlap one another in the second direction. When viewed from above or along the optical axis, the protrusions 1066A, 1066B, the magnet 1031, and the second magnet unit 1310B may overlap one another in the third direction.

[0643] Fig. 28a is a diagram for explaining electromagnetic forces F1 and F2 due to the interaction between magnet units 1310A and 1310B and coil units 1230A and 1230B and the operation of moving plate 1060, and Fig. 28b shows the movement of OIS operating part 1100 due to the electromagnetic forces of Fig. 28a. Fig. 28a shows the electromagnetic forces when first and second magnet units 1310A and 1310B are two-pole magnets having a north pole and a south pole.

[0644] 28a and 28b, the operation of the OIS operating unit by the OIS driving unit will be described. The OIS driving unit may include a coil 1230 and a magnet 1310. The OIS driving unit may also include a position sensor 1240.

[0645] A first electromagnetic force F1 may be generated by the interaction between the first magnet unit 1310A and the first coil unit 1230A. For example, the first electromagnetic force F1 may act in the optical axis direction, for example, in the upward or downward direction.

[0646] The first electromagnetic force F1 can tilt the OIS operating unit around a second axis (e.g., the Y-axis or the second protrusion 1066). For example, the first electromagnetic force F1 can tilt the OIS operating unit around the second axis. Here, the second axis (Y-axis) tilting can mean that the OIS operating unit tilts around the second axis (Y-axis) or that the OIS operating unit rotates left or right by a preset angle around the second axis (Y-axis) as the rotation axis.

[0647] For example, the first electromagnetic force F1 can cause the moving plate 1060 to tilt about a second axis (e.g., the Y axis or the protrusions 1066A and 1066B of the second protrusion 1066). For example, the first electromagnetic force F1 can cause the moving plate 1060 to tilt about the second axis.

[0648] 19b, in order for the OIS operating unit to tilt based on the second axis (or the second protrusion 1066 of the moving plate 1060), a gap or space may be formed between the moving plate 1060 and the OIS operating unit (e.g., the sensor base 1270) due to the first protrusion 1065 of the moving plate 1060. For example, a gap or space may be formed between the upper surface 1006A of the moving plate 1060 and the OIS operating unit (e.g., the sensor base 1270) that allows the moving plate 1060 to move. For example, the upper surface 1006A of the moving plate 1060 may be spaced apart from the OIS operating unit (e.g., the sensor base 1270) or the lower surface of the sensor base 1270.

[0649] A second electromagnetic force F2 may be generated by the interaction between the second magnet unit 1310B and the second coil unit 1230B. For example, the second electromagnetic force F2 may act in an upward direction or a downward direction.

[0650] The second electromagnetic force F2 can tilt the OIS operating unit around a first axis (e.g., the X-axis or ball member 1062). For example, the second electromagnetic force F2 can tilt the OIS operating unit around the first axis. Here, first-axis (X-axis) tilting can mean that the OIS operating unit tilts around the first axis (X-axis) or that the OIS operating unit rotates left and right by a preset angle around the first axis (X-axis) as the rotation axis.

[0651] For example, the second electromagnetic force F2 can cause the moving plate 1060 to tilt about a first axis (e.g., the X-axis or the ball member 1062). For example, the second electromagnetic force F2 can cause the moving plate 1060 to tilt about the first axis.

[0652] 19a and 28a, in order for the OIS operating part to tilt based on the first axis, a gap or space may be present between the moving plate 1060 and the moving part due to the first protrusion 1065 of the moving plate 1060.

[0653] For example, there may be a space or gap between the upper surface 1006A of the moving plate 1060 and the moving part (e.g., the lower surface of the sensor base 1270). For example, the upper surface 1006A of the moving plate 1060 may be spaced apart from the upper surface of the sensor base 1270.

[0654] For example, the first axis or second axis tilting may cause the moving plate 1060 to come into contact with the moving part (sensor base 1270) or the fixed part (e.g., housing 1210). Here, the moving part or the fixed part may act as a stopper that suppresses tilting of the OIS operating part.

[0655] In other embodiments, the first electromagnetic force due to the interaction between the first magnet unit and the first coil unit and the second electromagnetic force due to the interaction between the second magnet unit and the second coil unit may act in a direction different from the optical axis (e.g., a perpendicular direction, e.g., the X-axis direction or the Y-axis direction).

[0656] In a camera device in which the image sensor is fixed but the lens moves in a direction perpendicular to the optical axis for image stabilization or shake correction (hereinafter referred to as "Comparative Example 1"), image distortion may occur. Furthermore, in a camera device in which the lens is fixed and not moved but the image sensor is moved or tilted for image stabilization or shake correction (hereinafter referred to as "Comparative Example 2"), image distortion may occur at the edge or corner of the image sensor. In Comparative Examples 1 and 2, the image sensor and lens are separated, and only one of the image sensor and lens is moved or tilted, so image distortion may occur during image stabilization, making it difficult to achieve wide-angle image stabilization.

[0657] In this embodiment, for image stabilization, the OIS driver may tilt the OIS operating unit about a first axis or a second axis or rotate it within a preset angle range. In this embodiment, the OIS operating unit includes the lens module 1400 and the image sensor 1810. Therefore, when the OIS is driven, the tilting direction (or rotation direction) and tilting angle (or rotation angle) of the lens module (e.g., lens or lens barrel) 400 (or bobbin 1110) may be the same as or approximately the same as the tilting direction (or rotation direction) and tilting angle (or rotation angle) of the image sensor 1810.

[0658] In this embodiment, when the OIS is activated, the lens module 1400 (or bobbin 1110) and the image sensor 1810 can tilt or rotate together, resulting in no image distortion, 100% image resolution, and wide-angle image stabilization or shake correction.

[0659] In addition, in this embodiment, wideband shake correction is possible because the OIS operating unit including the lens module 1400 (or bobbin 1110) and the image sensor 1810 tilts or rotates. In addition, in this embodiment, image correction without mechanical distortion is possible, so compared to Comparative Examples 1 and 2, the load on the image processing is smaller, and current consumption can be reduced.

[0660] In addition, in this embodiment, a moving plate 1060 is used to tilt the OIS operating part, so compared to examples that simply use a ball member or a shaft member, the OIS operating part can be tilted stably, precisely, and accurately, thereby improving the reliability of the OIS drive.

[0661] In addition, in this embodiment, the bent portions 1804D, 1804E and the third portion 1804C of the fourth substrate 1804, which is a flexible substrate of the circuit board 1800, can reduce the power consumption required to drive the OIS.

[0662] In addition, in the embodiment, the moving plate 1060 is disposed within the seat portion 1069 of the housing 1210, and the protrusion portion 1049 of the housing 1210 overlaps with the opening 1060A of the moving plate 1060, thereby reducing the height or length of the camera device 1200 in the optical axis direction.

[0663] In addition, in this embodiment, at least a portion of the magnet 1031 is positioned within the opening 1060A of the moving plate 1060, so that the distance between the magnet 1031 and the magnetic body 1032 can be reduced, thereby increasing the attractive force or holding force for supporting the OIS operating part, and enabling stable OIS operation.

[0664] In addition, in the embodiment, the first magnet unit 1310A and the second magnet unit 1310B, which are driving magnets for image stabilization, are arranged in the lower part 1042 of the housing 1210, not in the sides 1071A to 1071D of the housing 1210, so that the thickness (or the length in the direction perpendicular to the optical axis) of the sides 1071A to 1071D of the housing 1210 can be reduced, thereby enabling the design of a camera device that can accommodate a large-diameter lens.

[0665] For example, the horizontal and vertical lengths of the camera device 1200 according to the embodiment may be 12 mm to 23 mm, and the height of the camera device 1200 may be 4 mm to 12 mm. For example, the horizontal and vertical lengths of the camera device 1200 may be the horizontal and vertical lengths of the cover member 1300, and the height of the camera device 1200 may be the distance from the bottom surface of the housing 1210 to the top surface of the top plate of the cover member 1300. The diameter of the lens attached to the camera device 1200 may be 9 mm to 19 mm. In other embodiments, the diameter of the lens attached to the camera device 1200 may be 9 mm to 15 mm. If the diameter of the lens exceeds 19 mm, the arrangement of the coil 1120 and the magnet 1130 may be impossible or the sizes of the coil 1120 and the magnet 1130 may be limited to an extent that they are insufficient for AF drive.

[0666] Furthermore, if a driving magnet for image stabilization is disposed on the side of the housing 1210, the length of the driving magnet in the optical axis direction may be restricted by the length of the driving magnet in the optical axis direction. However, in this embodiment, the driving magnet 1310 is disposed in the lower part 1042 of the housing 1210, so the length of the driving magnet in the optical axis direction is not limited, and the camera device 1200 can be designed to have a reduced length in the optical axis direction. Furthermore, in this embodiment, the driving magnet 1310 is disposed on the seating portions 1141A and 1141B of the housing 1210, so the length of the camera device 1200 in the optical axis direction can be further reduced.

[0667] FIG. 29 is a perspective view of a camera device 1200 including a lens module 1400.

[0668] 29, the lens module 1400 may be coupled to the bobbin 110 and may move together with the bobbin 110 in the optical axis direction. For example, the lens module 1400 may include at least one of a lens and a lens barrel.

[0669] In an embodiment, during image stabilization or shake correction, the lens module 1400 and the image sensor 1810 may simultaneously tilt along the X axis or the Y axis by the same angle in the same direction.

[0670] 30a shows the OIS operating portion 1100 in a first position, and FIG. 30b shows the OIS operating portion 1100 in a second position.

[0671] 28a, 30a, and 30b, the OIS operating unit 1100 can tilt by a preset angle θ1 due to a force F1 generated by the interaction between the first magnet unit 1310A and the first coil unit 1230A. That is, when the OIS operating unit 1100 moves from the first position to the second position, the image sensor 1810 and the lens module 1400 can simultaneously tilt by the preset angle θ1. Furthermore, when the OIS operating unit 1100 moves from the first position to the second position, the moving plate 1060 can tilt by the preset angle θ1 together with the image sensor 1810 and the lens module 1400.

[0672] Therefore, the embodiment can obtain 100% image resolution without image distortion and can perform wide-angle image stabilization or shake correction. The description of Figures 30a and 30b can also be applied to the X-axis tilting of the OIS operating unit 1100, or can be applied by analogy.

[0673] Furthermore, the camera devices 200 and 1200 according to the embodiments may be included in optical instruments that form images of objects in space using the properties of light, such as reflection, refraction, absorption, interference, and diffraction, with the aim of enhancing the visual acuity of the eye, recording and reproducing images using lenses, or optical measurement, propagation and transmission of images, etc. For example, optical instruments according to the embodiments may be, but are not limited to, mobile phones, cellular phones, smartphones, portable smart devices, digital cameras, laptop computers, digital terminals, PDAs (Personal Digital Assistants), PMPs (Portable Multimedia Players), navigation devices, etc., and may be any device for taking videos or photographs.

While FIG. 31b shows an example where two rear cameras are arranged, in other embodiments, one or more rear cameras may be arranged. In other embodiments, the camera module 200, 1200 can be used as both a front camera and a rear camera.

[0676] Referring to Figures 31a, 31b and 32, the optical device (or "portable terminal") 200A may include a body 850, a wireless communication unit 710, an A / V input unit 720, a sensing unit 740, an input / output unit 750, a memory unit 760, an interface unit 770, a control unit 780, and a power supply unit 790.

[0677] The body 850 has a bar shape, but is not limited to this, and may have various structures such as a slide type, folder type, swing type, swivel type, etc., in which two or more sub-bodies are connected to be able to move relative to each other.

[0678] The wireless communication unit 710 may include one or more modules that enable wireless communication between the terminal 200A and a wireless communication system or between the terminal 200A and a network in which the terminal 200A is located. For example, the wireless communication unit 710 may include a broadcast receiving module 711, a mobile communication module 712, a wireless Internet module 713, a short-range communication module 714, and a location information module 715.
