[0033] The embodiment can reduce the space required for tilting the sensor base, which is the OIS moving part, for image stabilization, thereby reducing the size of the camera device.

[0034] In this embodiment, the support member coupled to the moving module can function as a magnetic material that generates a repulsive force to support the OIS moving part.

[0035] The embodiment can reduce the number of parts and reduce the weight of the camera device.

[0036] Furthermore, in this embodiment, a tilt guide is used for tilting the OIS moving part. Compared to examples that simply use ball members or shaft members, the OIS moving part can be tilted stably, precisely, and accurately, thereby improving the reliability of the OIS drive.

[0037] Furthermore, in this embodiment, a magnetic material is not used to generate the holding force for pressing the tilt guide portion that supports the OIS moving portion, and instead an elastic member is used.

[0038] In this embodiment, by using an elastic member, magnetic field interference between the magnetic material and the drive magnet can be prevented, thereby achieving a stable and desired holding force.

[0039] In this embodiment, the use of an elastic member allows for easy and flexible selection of the axis for module tilting, and enables the realization of a linear holding force with respect to the stroke or displacement of the OIS moving part.

[0040] The embodiment can reduce the space required for tilting the sensor base, which is the OIS moving part, for image stabilization, thereby reducing the size of the camera device. [Brief explanation of the drawing]

[0127] Hereinafter, embodiments of the present invention that can specifically achieve the above objectives will be described with reference to the attached drawings.

[0128] In the description of the embodiments, when it is stated that a component is formed "on or under" an element, "on or under" includes all cases where two elements are in direct contact or where one or more other elements are positioned indirectly between the two elements. Furthermore, when expressed as "on or under," it may include not only an upward direction but also a downward direction relative to one element.

[0129] Furthermore, relational terms such as “first” and “second,” “upper / top / upper,” and “lower / bottom / lower” used below may be used solely to distinguish one entity or element from another, without necessarily requiring or implying any physical or logical relationship or order between the entities or elements. Also, the same reference number refers to the same element throughout the drawing description.

[0130] Furthermore, unless otherwise stated, terms such as "includes," "constitutes," or "possesses" used above mean that the component in question may be inherent, and should be interpreted as including other components rather than excluding them. In addition, terms such as "correspond" used above may include at least one of the meanings of "opposite" or "superimposed."

[0131] The camera device and optical equipment including it according to the embodiment will be described below with reference to the attached drawings. For convenience of explanation, the camera device according to the embodiment will be described using the Cartesian coordinate system (x, y, z), but it may be described using other coordinate systems, and the embodiment is not limited thereto. In each figure, the X axis and Y axis may be axes perpendicular to the Z axis, which is the optical axis OA direction.

[0132] Furthermore, the Z-axis direction, which is the optical axis direction 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 the direction perpendicular to the imaging area of ​​the image sensor.

[0133] Furthermore, the X-axis (or Y-axis) may be referred to as the "first horizontal axis," and the direction of the X-axis (or Y-axis) may be referred to as the "first horizontal direction," the Y-axis (or X-axis) may be referred to as the "second horizontal axis," and the direction of the Y-axis (or X-axis) may be referred to as the "second horizontal direction." For example, the direction of the optical axis may be the direction of the optical axis or a direction parallel to the optical axis. Also, the direction of the first axis may be a direction parallel to the first axis, and the direction of the second axis may be a direction parallel to the second axis.

[0134] Furthermore, for example, the optical axis may be the optical axis of a lens mounted on a lens barrel. Alternatively, for example, the optical axis may be an axis perpendicular to the imaging area of ​​an image sensor and passing through the center of the imaging area. Also, the term "terminal" below may be replaced with "pad," "electrode," or "conductive layer."

[0135] Furthermore, in the embodiment, with respect to the connection between projections and holes for joining two components together, one of the components may be a connecting projection (or connecting hole), and the other component may be a corresponding connecting hole (or connecting projection).

[0136] The camera device according to this embodiment may perform image stabilization and autofocus functions. The "image stabilization function" may be a function that moves the lens perpendicular to the optical axis or tilts the lens based on the optical axis to counteract vibrations (or movements) caused by the user's hand shake. The "autofocus function" may be a function that moves the lens in the optical axis direction according to the distance to the subject in order to obtain a clear image of the subject on the image sensor, thereby automatically focusing on the subject. Hereinafter, "camera device" may be replaced with "camera," "actuator," "camera module," "imaging device," or "photography device."

[0138] Referring to Figures 1 to 13, the camera device 200 may include a fixed part, an AF moving part, an OIS moving part 100, and a support part. The OIS moving part 100 may be replaced with "moving part," "oscillating part," or "movable part."

[0139] The fixed part can be a fixed element. That is, the fixed part does not have to move in the direction of the optical axis. Alternatively, the fixed part does not have to move or tilt in a direction perpendicular to the optical axis. Furthermore, a configuration coupled to the fixed part can also be considered a fixed part.

[0140] The fixing portion may include a housing 210. The fixing portion may include a cover member 300. For example, the fixing portion may include a configuration that is arranged on or coupled to the housing 210 or the cover member 300. For example, the fixing portion may include at least one of a magnet 310, a magnetic body 31, and a movement-restricting portion 80 arranged on the housing 210.

[0141] The AF moving part can move in the optical axis direction relative to the fixed part. For example, the AF moving part may include a bobbin 110. In other embodiments, the AF moving part may further include a configuration coupled to the bobbin 110 (e.g., a magnet 130). In other embodiments, the AF moving part may further include a lens module 400 (see Figure 17) coupled to the bobbin 110.

[0142] The OIS moving unit 100 (see Figure 2a) is movable or tiltable to the left or right with respect to a first axis (e.g., Pitch) that intersects the optical axis relative to the fixed unit. The OIS moving unit is also movable or tiltable to the left or right with respect to a second axis (e.g., Yaw) that intersects the optical axis relative to the fixed unit. For example, the first axis may be perpendicular to the optical axis direction, and the second axis may be perpendicular to both the optical axis direction and the first axis. For example, the first axis may intersect the X axis or the Y axis. For example, the second axis may intersect the X axis or the Y axis. For example, the first and second axes may be perpendicular to each other. In other embodiments, for example, the first axis may be either the X axis or the Y axis, and the second axis may be the other of the X axis and the Y axis.

[0143] For example, the OIS moving unit 100 may include an AF moving unit. Furthermore, the OIS moving unit may include an image sensor 810. The OIS moving unit 100 may include a circuit board 800 on which the image sensor 810 is arranged. The OIS moving unit 100 may also include a sensor base 270 on which at least a portion of the circuit board 800 is arranged. Furthermore, the OIS moving unit may include a holder 140 that is coupled to the sensor base 270.

[0144] The OIS moving part 100 may be represented as a first moving part (or first movable part), and the AF moving part may be replaced by a second moving part (or second movable part). For example, the first moving part may include a sensor base 270 and a circuit board 800.

[0145] Furthermore, the OIS moving unit 100 may include a configuration in which it is disposed of or coupled to at least one of the holder 140, the sensor base 270, and the circuit board 800. For example, the OIS moving unit 100 may include a filter 610 disposed on the holder 140. For example, the OIS moving unit 100 may include a support member 64 coupled to the sensor base 270. For example, the OIS moving unit 100 may include a magnetic body 33 coupled to the support member 64.

[0146] For example, the OIS moving unit 100 may include at least one of the following, which are arranged on the circuit board 800: an image sensor 810, sensors 170 and 240, coils 120 and 230, a circuit element 815, and a control unit 830.

[0147] Furthermore, the OIS moving unit 100 may include a moving module (or tilt module) and a support member 64. For example, the moving module (or tilt module) may include at least one of the remaining components of the OIS moving unit 100 described above, excluding the support member 64. The moving module can be replaced with the term "mover".

[0148] For example, the moving module (or tilt module) may include a lens module 400 and an image sensor 810. Alternatively, for example, the moving module (or tilt module) may include a sensor base 270. Furthermore, for example, the moving module (or tilt module) may further include at least one of a holder 140 and a circuit board 800. For example, the moving module (or tilt module) may be tiltable with respect to a first or second axis.

[0149] The support portion can support the OIS moving portion relative to the fixed portion. For example, the support portion may include a tilt guide portion 60. In other embodiments, for example, the support portion may further include a rolling member (e.g., a ball member) or a sliding member (e.g., a shaft).

[0150] The bobbin 110 is for housing a lens or lens barrel and may be located within the holder 140. Alternatively, the bobbin 110 may be located within the cover member 300. The bobbin 100 may be located within the cover member 300. The bobbin 110 may be replaced with "lens holder" or "lens carrier".

[0151] The bobbin 110 can move in the optical axis direction. For example, due to the electromagnetic interaction between the coil 120 and the magnet 130, the bobbin 110 can move in a first direction (e.g., the Z-axis direction). The coil 120 and the magnet 130 may be an AF drive unit that moves or drives the AF moving unit. The bobbin 110 may also be included in the OIS moving unit 100, and the bobbin 110 may be tilted or rotated by a predetermined angle with respect to a first or second axis.

[0152] Referring to Figure 5, the bobbin 110 may include an aperture 101 for coupling with the lens module 400. The aperture 101 may be a hole or hollow that penetrates the bobbin 110 in the optical axis direction. The shape of the aperture 101 of the bobbin 110 may match the shape of the lens module 400 to which it is mounted or coupled, and may be, for example, circular, elliptical, or polygonal.

[0153] Although not shown in Figure 1, the bobbin 110 may include at least one stopper located on at least one of its top and bottom surfaces. The stopper of the bobbin 110 may be a structure that protrudes from the top (or bottom) surface of the bobbin 110 in a first direction or upward (or downward) direction, and can prevent the top (or bottom) surface of the bobbin 110 from directly colliding with the inner surface of the top plate 301 of the cover member 300 (or the lower part of the holder 140).

[0154] The bobbin 110 may include a mounting portion 115 for mounting or positioning the magnet 130. For example, the mounting portion 115 may be a groove recessed from the outer surface of the bobbin 110.

[0155] Referring to Figure 6, the bobbin 110 may include multiple sides 110A to 110D, i.e., outer sides. For example, the bobbin 110 may include a first side 110A, a second side 110B, a third side 110C, and a fourth side 110D.

[0156] For example, the second side surface 110B may be opposite the first side surface 110A, or it may be located on the opposite side of the first side surface 110A with respect 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 be opposite the third side surface 110C, or it may be located on the opposite side of the third side surface 110C with respect to the optical axis OA. Figure 6 shows an example in which the bobbin 110 includes four sides, but in other embodiments it may include three or five or more sides.

[0157] For example, the mounting portion 115 may be formed on the first side surface 110A of the bobbin. For example, the lower part of the mounting portion 115 may be closed and not open to the lower surface of the bobbin 110. The upper part of the mounting portion 115 may also be closed and not open to the upper surface of the bobbin 110. In another embodiment, for example, the mounting portion 115 may include an opening that opens to at least one of the upper or lower surfaces of the bobbin 110.

[0158] The bobbin 110 may include a housing portion 112 for housing at least a portion of the rolling member 21. For example, at least a portion of the housing portion 112 may be located on the first side surface 110A of the bobbin 110. The housing portion 112 may be a groove recessed from the outer surface (e.g., the first side surface 110A) of the bobbin 110. The housing portion 112 may be replaced with "housing groove," "groove," or "guide groove." To reduce friction with the rolling member 21, a lubricant (e.g., grease) may be placed in the housing portion 112 of the bobbin 110.

[0159] For example, the bobbin 110 may include a first housing section 112A for housing the rolling member 21A, and a second housing section 112B for housing the rolling member 21B. For example, the mounting section 115 may be positioned between the first housing section 112A and the second housing section 112B.

[0160] For example, the first housing section 112A (or the second housing section 112B) may include an opening that opens to the upper surface of the bobbin 110. In other embodiments, the upper parts of the housing sections 112A and 112B may be closed and not open to the upper surface of the bobbin 110. For example, the lower parts of the housing sections 112A and 112B may be closed and not open to the lower surface of the bobbin 110. For example, the housing section 112 may be formed to extend in the direction of the optical axis. For example, the housing section 112 may be extended in the direction of the optical axis so as to be formed between the upper and lower surfaces of the bobbin 110.

[0161] For example, when viewed from above, the shape of the storage section 112 may be triangular, but is not limited to this, and could be a polygon (for example, a quadrilateral or a pentagon). Also, when viewed from above, the storage section 112 may be V-shaped or U-shaped.

[0162] The magnet 130 can be placed on, coupled to, or fixed to the bobbin 110. For example, the magnet 130 can be placed on or coupled to the first side surface 110A of the bobbin 110. For example, the magnet 130 can be placed within or coupled to the mounting portion 115 of the bobbin 110. For example, the magnet 130 can be placed between the first rolling member 21A and the second rolling member 21B.

[0163] The shape of the magnet 130 may correspond to the shape of the first side surface 110A of the bobbin 110, for example, a rectangular parallelepiped shape. In another embodiment, for example, at least one of the ends of the magnet 130 may be tapered.

[0164] For example, the magnet 130 may include a first side surface 13A facing the coil 120 and a second side surface 13B which is the opposite side of the first side surface 13A. The first side surface 13A of the magnet 130 may be exposed from the first side surface 110A of the bobbin 110.

[0165] Furthermore, to improve the electromagnetic force, the magnet 130 may be a four-pole magnet. For example, the magnet 130 may include two north poles and two south poles. For example, the magnet 130 may include a first magnet including north and south poles, a second magnet including south and north poles, and a partition wall positioned between the first and second magnets. In this case, the partition wall is a substantially non-magnetic portion, includes a section with little polarity, may be filled with air or composed of a non-magnetic material, and may be referred to as the "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 positioned such that their polarities face each other in the optical axis direction.

[0166] In other embodiments, the magnet 130 may be a bipolar magnet having an interface that is naturally formed between two mutually different polarities. For example, in other embodiments, the magnet 130 may include one north pole and one south pole. For example, the magnet 130 may be a magnet that is divided or arranged as a north pole and a south pole along the optical axis. In other embodiments, the magnet 130 may be a bipolar magnet that is divided as a north pole and a south pole in a direction perpendicular to the optical axis.

[0167] The holder 140 may be located inside the cover member 300. The holder 140 may include a cavity for housing the bobbin 110. The holder 140 may include an opening 30A corresponding to the opening 101 of the bobbin 110. For example, the opening 30A may be a through hole or hollow to expose at least a portion of the bobbin 110 (or lens module 400). Alternatively, for example, the opening 30A of the holder 140 may expose the imaging area of ​​the image sensor 810. The holder 140 may be replaced with "housing". 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 hollow that penetrates the holder 140 in the optical axis direction. The opening 30A of the holder 140 may have a shape corresponding to the shape of the bobbin 110, such as a polygon (e.g., a quadrilateral or octagon) or a circle (or ellipse), but is not limited to these, and can have various shapes.

[0168] The holder 140 may include a plurality of side sections 41A to 41D. The holder 140 is located between two adjacent side sections and may include a corner connecting the two adjacent side sections. The holder 140 may include a first side section 41A corresponding to or facing the first side section 110A of the bobbin 110, a second side section 41B corresponding to or facing the second side section 110B of the bobbin 110, a third side section 41C corresponding to or facing the third side section 110C of the bobbin 110, and a fourth side section 41D corresponding to or facing the fourth side section 110D of the bobbin 110.

[0169] The first side portion 41A (or first side or first outer surface) of the holder 140 may be located on the opposite side of the second side portion 41B (or second side or second outer surface) of the holder 140 with respect to the optical axis. Also, the third side portion 41C (or third side or third outer surface) of the holder 140 may be located on the opposite side of the fourth side portion 41D (or fourth side or fourth outer surface) of the holder 140 with respect to the optical axis. The first to fourth side portions 41A to 41D of the holder 140 may each be arranged parallel to any one of the corresponding side plates 302 of the cover member 300.

[0170] Referring to Figures 7a and 7b, the holder 140 may include a mounting portion 142A for arranging the coil 120. For example, the mounting portion 142A may be located on or formed on the first side portion 41A of the holder 140. For example, the mounting portion 142A may be a through-hole penetrating the first side portion 41A of the holder 140. Because the mounting portion 142A is in the form of a through-hole, a portion of the holder 140 may not be interposed between the coil 120 and the magnet 130, thereby increasing the electromagnetic force between the magnet 130 and the coil 120. Also, because a portion of the holder 140 may not be interposed between the position sensor 170 and the magnet 130, the output of the position sensor 170 can be increased, and the sensitivity of the position sensor 170 can be improved. Furthermore, because a portion of the holder 140 is not interposed between the coil 120 and the magnet 130, the size of the camera device can be reduced. In another embodiment, the mounting portion 142A may be a groove formed in the outer (or inner) surface of the first side portion 41A of the holder 140.

[0171] The holder 140 may include a groove 142 for accommodating at least a portion of the circuit board 800, for example, at least a portion of the second board 802. Because at least a portion of the second board 802 is positioned within the groove 142 of the holder 140, the second board 802 and the magnetic material 82 can be prevented from protruding from the outer surface of the first side portion 41A of the holder 140, or from protruding excessively from the outer surface of the first side portion 41A. That is, the second board 802 and the magnetic material 82 can protrude less than the sum of the thicknesses of the second board 802 and the magnetic material 82, with respect to the outer surface of the first side portion 41A of the holder 140. This prevents an increase in the size of the camera device 200 in the direction perpendicular to the optical axis.

[0172] Referring to Figures 7a and 7b, the holder 140 may include a housing 116 for arranging or housing at least another portion of the rolling member 21. For example, at least a portion of the housing 116 may be located on the first side 41A of the holder 140. The housing 116 may be a groove recessed from the inner surface of the holder 140 (e.g., the inner surface of the first side 41A). The housing 116 may be replaced with "housing groove," "groove," or "guide groove." At least a portion of the housing 116 of the holder 140 may correspond to, face, or overlap with the housing 112 of the bobbin 110.

[0173] For example, the holder 140 may include a first housing section 116A for housing at least the other parts of the first rolling members 21A; B1, B2, and a second housing section 116B for housing at least the other parts of the second rolling members 21B; B3, B4. For example, the mounting section 142A of the holder 140 may be located between the first housing section 116A and the second housing section 116B of the holder 140.

[0174] For example, the first housing section 116A (or the second housing section 116B) may include an opening that opens to the upper surface of the holder 140. In other embodiments, the upper part of the housing section 116 may be closed and not open to the upper surface of the holder 140. For example, the lower part of the housing section 116 may be closed and not open to the lower surface of the holder 140. For example, the housing section 116 may be formed to extend in the direction of the optical axis. For example, the housing section 116 may extend in the direction of the optical axis so as to be formed between the upper and lower surfaces of the holder 140. For example, when viewed from above, the shape of the housing section 116 of the holder 140 may be triangular, but not limited to this, and may be polygonal (e.g., quadrilateral or pentagon). Or, for example, when viewed from above, the housing section 116 may be V-shaped or U-shaped.

[0175] For example, when viewed from the optical axis direction or from above, the housing portion 116 may face or overlap with the upper plate 301 of the cover member 300. For example, at least a portion of the upper plate 301 of the cover member 300 may cover the housing portion 116.

[0176] The camera device 200 may include a rolling member 21 positioned between the bobbin 110 and the holder 140. The rolling member 21 may be replaced with "ball member," "ball," or "ball bearing."

[0177] At least a portion of the rolling member 21 can be in contact with the bobbin 110 and the holder 140, and by rolling or rotating between the bobbin 110 and the holder 140, it can support the movement of the bobbin 110 in the optical axis direction. 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. Due to the rolling or rotation of the rolling member 21, the bobbin 110 can slide or move in the optical axis direction in contact with the rolling member 21.

[0178] For example, the rolling member 21 may be made of a metal, plastic, or resin material, but is not limited to these. 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.

[0179] For example, the rolling member 21 may be positioned between the outer surface of the bobbin 110 and the inner surface of the holder 140. For example, the rolling member 21 may be positioned between the first side surface 110A of the bobbin 110 and the first side portion 41A of the holder 140. For example, the rolling member 21 may be positioned between the housing portion 112 of the bobbin 110 and the housing portion 116 of the holder 140. For example, at least a portion of the rolling member 21 may be in contact with the housing portion 112 of the bobbin 110, and at least another portion of the rolling member 21 may be in contact with the housing portion 116 of the holder 140.

[0180] 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. For example, the rolling member 21 may include a first rolling member 21A positioned between the first housing portion 112A of the bobbin 110 and the first housing portion 116A of the holder 140, and a second rolling member 21B positioned between the second housing portion 112B of the bobbin 110 and the second housing 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 multiple balls B1, B2.

[0181] 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, B4. In other embodiments, the first rolling member 21A and the second rolling member 21B may each include one ball.

[0182] For example, the first rolling member 21A and the second rolling member 21B may each include three or more balls. For example, the first rolling member 21A and the second rolling member 21B may each 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 balls, and the diameter of the lowest ball may be larger than the diameter of the intermediate balls. Furthermore, the diameters of the highest ball and the lowest ball may be the same as each other. In other embodiments, the diameters of the highest ball, the lowest ball, and the intermediate ball may be the same as each other.

[0183] For example, the first rolling member 21A and the second rolling member 21B may each include a first ball (highest ball), a second ball (lowest ball), and a third ball (intermediate 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 as each other.

[0184] For example, the diameters of the first ball and the second ball may be between 0.85 mm and 0.95 mm, respectively, and the diameter of the third ball may be between 0.75 mm and 0.85 mm.

[0185] In another embodiment, the first rolling member 21A and the second rolling member 21B may each include four balls, the diameter of the largest ball and the diameter of the smallest 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.

[0186] When viewed from above, the coil 120 and magnet 130 may be positioned between the first rolling member 21A and the second rolling member 21B. This prevents the bobbin 110 from tilting as it moves in the optical axis direction, allowing the rolling member 21 to stably support the bobbin 110 and improving the reliability of autofocus.

[0187] In other embodiments, the first rolling member 21A and the second rolling member 21B may be in the form of a shaft or a roller, respectively. In other embodiments, the ball members 21A and 21B may be replaced with sliding members (e.g., shafts) or rollers.

[0188] The camera device 200 may include a magnetic body 82 that acts attractively to 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 located in the holder 140. In another embodiment, the magnetic body 82 may be located in the housing 210.

[0189] The magnetic material 82 may be composed of a substance that adheres to a magnet. For example, the magnetic material 82 may be composed of a metallic material. Or, for example, the magnetic material 82 may be composed of a magnetic metallic material. Or, for example, the magnetic material 82 may be a magnet.

[0190] The magnetic material 82 can be replaced with a "yoke" or "metal plate." The magnetic material 82 can also play a role in improving or increasing the electromagnetic force between the magnet 130 and the coil 120.

[0191] Since the magnet 130 is placed on the bobbin 110 and the magnetic body 82 is placed on the holder 140, the attractive force acting between the magnetic body 82 and the magnet 130 can pull the bobbin 110 toward the holder 140 where the magnetic body 82 is located. Due to the attractive force between the magnetic body 82 and the magnet 130, the bobbin 110 and the holder 140 can press against the rolling member 21, and the bobbin 110 can be stably supported. The magnetic body 82 and the magnet 130 may be a "pressing unit" or "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. In other words, due to the attractive force between the magnet 130 and the magnetic body 82, the rolling member 21 can stably support the bobbin 110 relative to the holder 140.

[0192] In other embodiments, the magnet 130 may be located in the holder 140 and the coil 120 may be located in the bobbin 110. For example, the magnetic material 82 may be located in the holder 140 together with the magnet 130. For example, the magnet 130 may be located between the magnetic material 82 and the coil 120. In yet another embodiment, the magnetic material 82 may be located in the bobbin 110 together with the coil 120, facing the magnet 130 located in the holder 140. In yet another embodiment, the camera device 200 may further include a conductive member for electrically connecting the coil 120 located in the bobbin 110 to the second substrate 802 of the circuit board 800.

[0193] Referring to Figure 7b, the holder 140 may include a mounting section 45A for mounting or positioning the filter 610. The mounting section 45A may be located on or formed on the lower surface of the holder 140. For example, the mounting section 45A may be a groove recessed from the lower surface of the holder 140. For example, the mounting section 45A may include a bottom surface 5A that is stepped in the optical axis direction from 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 mounting section 45A. For example, the opening 30A may penetrate the bottom surface 5A of the mounting section 45A.

[0194] The holder 140 may include a recess 45B positioned or formed in the corner region of the inner surface of the mounting portion 45A. The recess 45B may have a structure that is recessed toward the corner region of the inner surface of the mounting portion 45A from the optical axis. The recess 45B can prevent the adhesive (e.g., UV epoxy) used to bond or attach the filter 610 to the mounting portion 45A from overflowing outside the mounting portion 45A.

[0195] The holder 140 may include relief grooves 46 to avoid spatial interference with the circuit element 815. For example, the relief grooves 46 may be located or formed on the lower surface of the holder 140. For example, the relief grooves 46 may be recessed from the lower surface of the holder 140. For example, the relief grooves 46 may correspond to, face, or overlap with the circuit element 815 in the optical axis direction. For example, the relief grooves 46 may be located between the mounting portion 45A and the side of the lower surface of the holder 140. For example, the relief grooves 46 may include a first relief groove 46A and a second relief groove 46B located on opposite sides of each other with respect to the mounting portion 45A or the filter 610. In other embodiments, the relief grooves 46 may include four relief grooves located between the opening 30A and the four sides of the holder 140.

[0196] The holder 140 may include a groove 47 corresponding to a projection 216 of the sensor base 270. The projection 216 of the sensor base 270 and the groove 47 of the holder 140 can serve as guides for easy assembly of the sensor base 270 and the holder 140, increasing the bonding area and improving the bonding force between the sensor base 270 and the holder 140.

[0197] For example, the groove 47 may be recessed from the lower surface of the holder 140. For example, the groove 47 may be located or formed in a corner or corner region of the lower surface of the holder 140. The groove 47 of the holder 140 may have a shape corresponding to the projection 216 of the sensor base 270. The holder 140 may also include a groove 48 or hole corresponding to the projection 17 of the sensor base 270. For example, the projection 17 of the sensor base 270 may be inserted into or coupled to the groove 48 of the holder 140. For example, the groove 48 may be located 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.

[0198] In other embodiments, the holder 140 may include a projection protruding from the lower surface of the holder 140 instead of the groove 47. The sensor base 270 may include a groove recessed from the upper surface of the sensor base 270 and coupled with the projection of the holder 140 instead of the projection 216. In other embodiments, the projection 17 may be formed on the holder 140 and the groove 48 may be formed on the sensor base 270.

[0199] The camera device 200 may include a filter 610 that is positioned on or coupled to the holder 140. For example, the filter 610 may be positioned below the holder 140. The filter 610 may be positioned between the lens module 400 and the image sensor 810. For example, the filter 610 may be coupled to the lower surface of the holder 140. For example, the filter 610 may be positioned on the mounting portion 45A of the holder 140.

[0200] The filter 610 can serve to block light of a specific frequency band from entering the image sensor 810 from the light passing through the lens module 400. For example, the filter 610 may be an infrared cut filter. For example, the filter 610 may be positioned parallel to a plane perpendicular to the optical axis OA.

[0201] The filter 610 may be bonded to the holder 140 (or mounting portion 45A) by an adhesive (not shown). For example, the edge region of the filter 610 may be bonded to the bottom surface of the mounting portion 45A.

[0202] For example, the adhesive may be epoxy, thermosetting adhesive, UV-curing 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 image sensor 810 in the optical axis direction.

[0203] The sensor base 270 may be located below the holder 140. The sensor base 270 may be located below the filter 610. For example, the sensor base 270 may be located below the image sensor 810. For example, the sensor base 270 may be located below the circuit board 800.

[0204] The sensor base 270 may be coupled with the holder 140. The sensor base 270 may be referred to as the "holder." The holder 140 may be referred to as the "first housing" (or "first holder"), and the sensor base 270 may be referred to as the "second housing" (or "second holder"). Alternatively, the holder 140 and the sensor base 270 may not be distinguished and may be referred to as a single term, such as "housing" (or "holder"). In other embodiments, the sensor base 270 and the holder 140 may be formed integrally. In yet another embodiment, the sensor base 270, the holder 140, and at least two of the support member 64 may be formed integrally.

[0205] For example, the sensor base 270 may include a projection 216 that protrudes from the top surface. The projection 216 can be replaced with the term "column."

[0206] 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 bonded to the groove 47 of the holder 140. For example, at least a portion of the protrusion 216 may be bonded to the groove 47 of the holder 140 by an adhesive.

[0207] For example, the sensor base 270 may include a main body 270A and a projection 216 protruding from the upper surface of the main body 270A. For example, the main body 270A may have a shape corresponding to the first substrate 801 of the circuit board 810. For example, the main body 270A may have a polyhedron shape, such as a hexahedron. For example, the projection 216 may be located in the corner region of the upper surface of the main body 270A. For example, the projection 216 may include four projections 216A to 216D located in the four corner regions of the upper surface of the main body 270. Also, for example, the holder 140 may include four grooves 47 corresponding to the four projections 216A to 216D. In another embodiment, the housing 210 may include at least one projection located in at least one of the four corner regions of the upper surface of the main body 270, and the holder 140 may include at least one groove 48 corresponding to at least one projection of the housing 210.

[0208] The sensor base 270 or main body 270A may include side portions 51A to 51D that correspond to, oppose, or overlap with the side portions 41A to 41D of the holder 140. The sensor base 270 may include corners positioned between the side portions 51A to 51D. For example, the sensor base 270 may include a first corner to a fourth corner.

[0209] The camera device 200 may include a gyro sensor (not shown) located on the circuit board 800. For example, the gyro sensor may be located on a first substrate 801 of the circuit board 800. For example, the gyro sensor may be located, coupled, or fixed to the underside of the first substrate 801. For example, the gyro sensor outputs rotational angular velocity information due to the movement of the camera device 200. For example, the gyro sensor may be implemented as a two-axis or three-axis gyro sensor, or as an angular velocity sensor. For example, the gyro sensor may be electrically or electrically connected to the first substrate 801.

[0210] In other embodiments, the sensor base 270 may include a housing for which a gyro sensor is positioned or to avoid spatial interference with the gyro sensor 820. For example, the housing may be a through-hole penetrating the sensor base 270 in the optical axis direction, or a groove recessed from the upper surface of the sensor base 270 or the upper surface of the main body 270A. In this case, the housing may include an opening that opens to the outer surface of the sensor base 270.

[0211] The sensor base 270 may house the control unit 830 or include a housing 255 for housing the control unit 830. The housing 255 may be a groove recessed from the upper surface of the sensor base 270 or the upper surface of the main body 270A. In other embodiments, the housing 255 may be a through-hole penetrating the sensor base 270 or the main body 270A in the optical axis direction.

[0212] The sensor base 270 may include mounting sections 274A and 274B for arranging the coils 230. The mounting sections 274A and 274B may be arranged or formed on the upper surface of the sensor base 270. For example, the mounting sections 274A and 274B may be grooves recessed from the upper surface of the sensor base 270. For example, the sensor base 270 may include a first mounting section 274A for arranging or mounting a first coil unit 230A and a second mounting section 274B for arranging or mounting a second coil unit 230B.

[0213] For example, the first mounting portion 274A may be formed adjacent to or in contact with any one of the protrusions 216A to 216D of the sensor base 270 (e.g., 216C). For example, the first mounting portion 274A may be a groove formed on the upper surface of the sensor base 270 adjacent to the third protrusion 216C of the sensor base 270. For example, the first mounting portion 274A may include an opening that opens to the outer surface of a side portion (e.g., 51B, 51D) of the sensor base 270 adjacent to the third protrusion 216C. In other embodiments, the first mounting portion 274A may be spaced apart from the outer surface of the side portion (e.g., 51B, 51D) of the sensor base 270 and may not include an opening that opens to the outer surface of the side portion 51B, 51D.

[0214] For example, the second mounting portion 274B may be formed adjacent to or in contact with any one of the other projections 216A to 216D of the sensor base 270 (e.g., 216D). For example, the second mounting portion 274B may be a groove formed on the upper surface of the sensor base 270 adjacent to the fourth projection 216D of the sensor base 270. For example, the second mounting portion 274B may include an opening that opens to the outer surface of a side portion (e.g., 51B, 51C) of the sensor base 270 adjacent to the fourth projection 216D. In other embodiments, the second mounting portion 274B may be spaced apart from the outer surface of the side portion (e.g., 51B, 51C) of the sensor base 270 and may not include an opening that opens to the outer surface of the side portion 51B, 51C.

[0215] In another embodiment, the mounting portion 274 of the sensor base 270 may be formed corresponding to the position where the coil 230 is placed.

[0216] In other embodiments, the mounting portions 274A and 274B may be through-holes. For example, at least one of the first mounting portion 274A and the second mounting portion 274B may be a hole or through-hole penetrating the sensor base 270 in the optical axis direction. In this case, a portion of the sensor base 270 may not be interposed between the coil 230 and the magnet 310, thereby increasing the electromagnetic force between the magnet 310 and the coil 230. Also, a portion of the sensor base 270 may not be interposed between the position sensor 240 and the magnet 310, thereby increasing the output of the position sensor 240 and improving the sensitivity of the position sensor 240. Furthermore, a portion of the sensor base 270 may not be interposed between the position sensor 240 and the magnet 310, thereby reducing the height of the camera device.

[0217] In other embodiments, the mounting portions 274A and 274B may be in the form of relief portions that avoid spatial interference with the entire coil 230.

[0218] The sensor base 270 may include grooves 29 in which at least a portion (e.g., projections 65) of the tilt guide portion 60 is positioned or accommodated. The grooves 29 may be formed on the lower surface of the sensor base 270. For example, the grooves 29 may be formed from the lower surface of the sensor base 270. For example, the number of grooves 29 may be the same as the number of projections 65 of the tilt guide portion 60.

[0219] For example, the groove 29 may include two grooves 29A and 29B that are spaced apart from each other. For example, the two grooves 29A and 29B may be spaced apart from each other in the first axial direction (see Figure 16a). For example, the extension 217 of the sensor base 270 may be positioned between the two grooves 29A and 29B of the sensor base 270.

[0220] The groove 29 may contact the projection 65 of the tilt guide portion 60 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. At least one side surface may be an inclined surface. For example, the groove 29 may include a bottom surface and a plurality of inclined surfaces. The shapes of the inclined surfaces of the groove 29 may be identical to each other. In other embodiments, at least one of the inclined surfaces of the groove 29 may have a different shape from the other inclined surfaces.

[0221] Referring to Figure 7a, a groove 212A may be formed in the projection 216 of the sensor base 270 into which at least a portion of the first substrate 801 of the circuit board 800 is inserted or positioned. For example, the corner of the first substrate 801 may be inserted into or coupled to the groove 212A of the projection 216 of the sensor base 270. For example, the groove 212A may be formed on the side of the projection 216 facing the corner of the circuit board 800. In addition, a groove 83 may be formed in at least one corner of the circuit board 800 for insertion into or coupling to the groove 212A of the projection 216. The groove 212A of the projection 216 of the sensor base 270 can serve as a coupling guide for coupling the first substrate 801 and the sensor base 270, and can serve to prevent the first substrate 801 from rotating or detaching from the sensor base 270.

[0222] The circuit board 800 can be placed on, coupled to, or fixed to the sensor base 270. For example, the circuit board 800 can be coupled to the sensor base 270 by adhesive or a fixing member.

[0223] The circuit board 800 may be placed on, coupled to, or fixed to the main body 270A of the sensor base 270. The circuit board 800 may include at least one of a rigid printed circuit board, a flexible printed circuit board, or a rigid-flexible printed circuit board. 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 replaced with "board portion," "board," or "printed circuit board."

[0224] For example, the circuit board 800 may include a first substrate 801 (or "first region") which is placed on, coupled to, or fixed to the sensor base 270. For example, the first substrate 801 may be placed on, coupled to, or fixed to the body 270A of the sensor base 270. For example, the lower surface of the first substrate 801 may be coupled to the upper surface of the sensor base 270 or the upper surface of the body 270A. For example, the lower surface of the first substrate 801 may be coupled to the upper surface of the sensor base 270 or the upper surface of the body 270A by adhesive.

[0225] The circuit board 800 may include a second board 802 (or "second region") which is connected to the first board 801 and is positioned, coupled, or fixed to the holder 140. For example, the second board 802 may be positioned, coupled, or fixed to the first side portion 41A of the holder 140.

[0226] In Figure 7a, the circuit board 800 includes one second board, but in other embodiments, the circuit board 800 may include a plurality of second boards arranged on at least one of the sides of the holder 140.

[0227] For example, the second substrate 802 may be connected to the first side surface of the first substrate 801. For example, the second substrate 802 may be bent from the first side surface of the first substrate 801 toward the first side portion 41A of the holder 140. For example, the second substrate 802 may be extended upward from the first substrate 801.

[0228] 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 801 and the third board 803.

[0229] 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.

[0230] 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 placed between two adjacent conductive layers. For example, a flexible printed circuit board may include a single conductive layer (or circuit pattern), a first insulating layer placed on the conductive layer, and a second insulating layer placed beneath 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 placed between the first and second conductive layers, a second insulating layer placed on the first conductive layer, and a third insulating layer placed beneath the second conductive layer.

[0231] The image sensor 810 may be located on the first substrate 801. The image sensor 810 may be located in the optical axis direction, opposite to, or overlapping with the lens module 400 and / or filter 610. For example, the image sensor 810 may be located on the top surface of the circuit board 800. For example, the image sensor 810 may be located on the top surface of the first substrate 801.

[0232] The image sensor 810 may include a sensor surface for sensing light. For example, the sensor surface may include an imaging area. Here, the imaging area may be replaced with an effective area, a light-receiving area, or an active area. For example, the imaging area may include multiple pixels on which an image is formed. The imaging area may correspond to, face, or overlap the lens module 400 and / or filter 610 in the optical axis direction.

[0233] The image sensor 810 can be electrically or electrically connected to the first substrate 801. For example, the image sensor 810 can be electrically connected to the first substrate 801 by a conductive member, such as a wire (not shown). For example, the first substrate 801 of the circuit board 800 may include a wire electrically connected to the image sensor 810 and at least one pad or terminal (not shown) electrically connected to it. For example, the pad or terminal electrically connected to the wire may be located on the upper surface of the first substrate 801.

[0234] The camera device 200 may include circuit elements 815 arranged on the first substrate 801. For example, the circuit elements 815 may include at least one of passive elements (e.g., capacitors or resistors), active elements (e.g., sensors, memory, driver ICs), or circuit patterns. For example, to avoid spatial interference with the image sensor 810, the circuit elements 815 may be placed between the image sensor 810 and the edge (e.g., side) of the first substrate 801.

[0235] The camera device 200 may include a control unit 830 located on the circuit board 800. For example, the control unit 830 may be a driver IC. For example, the control unit 830 may be located on the first board 801. For example, the control unit 830 may be located beneath the first board 801. For example, the control unit 830 may be located, coupled, or fixed to the underside of the first board 801. For example, the control unit 830 may be electrically or electrically connected to the first board 801.

[0236] For example, the control unit 830 is conductively or electrically connected to the coil 120 and can supply a drive signal to the first coil 120. The control unit 830 is conductively or electrically connected to the coil units 230A and 230B of the coil 230, can supply a first drive signal to the first coil unit 230A, and can supply a second drive signal to the second coil unit 230B.

[0237] The control unit 830 may be conductively or electrically connected to the position sensor 170. Also, the control unit 830 may be conductively or electrically connected to the position sensor 240.

[0238] For example, the control unit 830 can receive the output signal of the position sensor 170 and can control the drive signal (e.g., drive current) supplied to the coil 120 using the output signal of the position sensor 170.

[0239] For example, the control unit 830 can receive the output signal of the position sensor 240 and can control the drive signal (e.g., drive current) supplied to the coil 230 using the output signal of the position sensor 240. For example, the control unit 830 can receive the output signal of the first sensor 240A and can control the first drive signal (e.g., first drive current) supplied to the first coil unit 230A using the output signal of the first sensor 240A. Also, the control unit 830 can receive the output signal of the second sensor 240B and can control the second drive signal (e.g., second drive current) supplied to the second coil unit 230B using the output signal of the second sensor 240B.

[0240] The coils 120 and 230 may be arranged, coupled, or fixed to the circuit board 800. For example, the coil 120 may be conductively or electrically connected to the circuit board 800 (e.g., the second substrate 802) by a conductive adhesive or solder. For example, the coil 230 may be conductively or electrically connected to the circuit board 800 (e.g., the first substrate 801) by a conductive adhesive or solder.

[0241] The first coil unit 230A and the second coil unit 230B may be positioned on or coupled to the first substrate 801, and may be electrically or electrically connected to the first substrate 801. Referring to Figure 7b, for example, the first coil unit 230A and the second coil unit 230B may be positioned on, coupled to, or fixed to the underside of the first substrate 801. For example, the first coil unit 230A and the second coil unit 230B may be positioned between the first substrate 801 and the sensor base 270.

[0242] For example, the first coil unit 230A and the second coil unit 230B may be positioned adjacent to two adjacent corners of the first substrate 801. For example, for diagonal drive, the first coil unit 230A may be positioned adjacent to one corner of the first substrate 801 corresponding to the protrusion 216C of the sensor base 270 (or any corner of the sensor base 270), and the second coil unit 230B may be positioned adjacent to the other corner of the first substrate 801 corresponding to the protrusion 216D of the sensor base 270 (or any other corner of the sensor base 270). For example, the first coil unit 230A may be positioned adjacent to the protrusion 216C of the sensor base 270, and the second coil unit 230B may be positioned adjacent to the protrusion 216D of the sensor base 270.

[0243] In other embodiments, the first coil unit 230A and the second coil unit 230B may be positioned adjacent to two adjacent sides of the four sides of the first substrate 801.

[0244] The coil 120 can move the AF moving part (e.g., a bobbin) in the optical axis direction through interaction with the magnet 130. The coil 120 may be placed in the holder 140.

[0245] The coil 120 may be positioned 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 positioned in 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 positioned on the first side 41A of the housing 130. The coil 120 may be positioned within the mounting portion 142A of the holder 140.

[0246] For example, the coil 120 may be hollow or contain holes. 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 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 in which the length in the lateral direction (or third direction) is longer than the length in the vertical direction (or optical axis direction).

[0247] A drive signal may be applied to the coil 120 in order to generate an electromagnetic force through electromagnetic interaction with the magnet 130. For example, a drive signal may be applied to the coil 120 from the circuit board 800 or the control unit 830. In this case, the drive signal supplied to the coil 120 may be DC and may be in the form of voltage or current. In another embodiment, for example, the drive signal provided to the coil 120 may include at least one of a DC signal and an AC signal.

[0248] The coil 120, to which a drive signal is supplied, can electromagnetically interact with the magnet 130 located on the bobbin 110, and the electromagnetic force resulting from the electromagnetic interaction between the coil 120 and the magnet 130 can move the AF moving part in a first direction. The control unit 830 adjusts the magnitude and / or direction of the drive signal (e.g., drive current) to control the movement of the AF moving part in the first direction, thereby enabling the autofocus function to be performed.

[0249] For AF feedback drive, the camera device 200 may include a position sensor 170. The position sensor 170 may detect the position or displacement of the bobbin 110 in the optical axis direction. For example, the position sensor 170 may detect a magnet 130 placed on the bobbin 110. In another embodiment, a sensing magnet opposite to the position sensor 170 may be placed on the bobbin separately from the magnet 130, and the position sensor 170 may detect the sensing magnet or the magnetic field of the sensing magnet to detect the displacement of the bobbin.

[0250] For example, the position sensor 170 may be located in the holder 140. For example, the position sensor 170 may be located in the first side portion 41A of the holder 140. For example, the position sensor 170 may be located within the mounting portion 142A of the holder 140. For example, the position sensor 170 may be located within the hollow portion of the coil 120. In another embodiment, the position sensor 170 may be located outside the hollow portion of the coil 120.

[0251] For example, the position sensor 170 may be coupled to the circuit board 800. For example, it may be coupled to the circuit board 800 by conductive adhesive or solder. For example, the position sensor 170 may be electrically or conductively connected to the second substrate 802. For example, the position sensor 170 may be electrically or conductively connected to the second substrate 802 by conductive adhesive or solder.

[0252] For example, the position sensor 170 may be placed, coupled, or fixed to the first surface of the second substrate 802. For example, the position sensor 170 may correspond to, face, or overlap with the magnet 130 in a direction perpendicular to the optical axis or in a second direction.

[0253] The position sensor 170 can detect the displacement of the bobbin 110 in the optical axis direction. For example, the position sensor 170 can detect the magnetic field or the strength of the magnetic field of the magnet 130 attached to the bobbin 110 in response to the movement of the bobbin 110, and output an output signal.

[0254] For example, the position sensor 170 may be a Hall sensor. In this case, the position sensor 170 may include two input terminals to which a drive signal is applied and two output terminals to which an output signal is output. The circuit board 800 may be electrically 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 drive 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.

[0255] In other embodiments, the position sensor 170 may be implemented as 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 can send and receive data to and from the outside using protocol-based data communication, such as I2C communication.

[0256] For example, if the position sensor 170 is a driver IC that includes a Hall sensor, the position sensor 170 may include first and second terminals to which power or drive signals are input, a third terminal for a clock signal, a fourth terminal for a data signal, and fifth and sixth terminals for supplying drive signals to the coil 120. The first to sixth terminals of the position sensor 170 may be electrically or electrically connected to the circuit board 800.

[0257] The coil 230 interacts with the magnet 310 located in the housing 210, which is the fixed part, to tilt the OIS moving part or rotate it by a predetermined angle with respect to the first or second axis.

[0258] The coil 230 may face, correspond to, or overlap with the magnet 310 in the optical axis direction. The coil 230 may include a first coil unit 230A that corresponds to, faces, or overlaps with the first magnet unit 310A in the optical axis direction, and a second coil unit 230B that corresponds to, faces, or overlaps with the second magnet unit 310B in the optical axis direction. For example, the coil 230 may not overlap with the magnet 310 in a direction perpendicular to the optical axis.

[0259] For example, the coil 230 may be disposed below the coil 120. For example, the first coil unit 230A may be disposed in the first placement portion 274A of the sensor base 270, and the second coil unit 230B may be disposed in the second placement portion 274B of the sensor base 270.

[0260] For example, the first coil unit 23oA and the second coil unit 230B may each include a hollow or a hole. For example, the first coil unit 230A and the second coil unit 230B may each have a ring shape or a closed curve shape. For example, the first coil unit 230A and the second coil unit 230B may each be in a ring shape wound about a straight line parallel to the optical axis OA and perpendicular to the upper surface of the sensor base 270 or the upper surface of the main body 270A.

[0261] For example, referring to FIG. i6a, the first coil unit 230A may be in a ring shape in which the length in the lateral direction (or the direction parallel to the second axis) is longer than the length in the longitudinal direction (or the direction parallel to the first axis). For example, the second coil unit 230B may be in a ring shape in which the length in the longitudinal direction (e.g., the direction parallel to the first axis) is longer than the length in the lateral direction (or the direction parallel to the second axis).

[0262] For OIS feedback driving, the camera device 200 may include a position sensor 240. The position sensor 240 may detect the displacement or angular displacement of the OIS moving unit 100 due to the tilt or rotation of the OIS moving unit 100. The position sensor 240 may detect the magnetic field of the magnet 310.

[0263] For example, the position sensor 240 may include a first sensor 240A and a second sensor 240B. For example, at least a portion of the first sensor 240A may correspond to, face, or overlap with the first magnet unit 310A in the optical axis direction. For example, the center of the first sensor 240A may overlap with the first magnet unit 310A in the optical axis direction. For example, the first sensor 240A may detect the first magnet unit 310A (or the magnetic field of the first magnet unit 310A). For example, the first sensor 240A may detect an angle tilted with respect to the second axis of the OIS moving part 100. In other embodiments, the first sensor 240A may not overlap with the first magnet unit 310A and the second magnet unit 310B in the optical axis direction.

[0264] At least a portion of the second sensor 240B may correspond to, face, or overlap with the second magnet unit 310B in the optical axis direction. For example, the center of the second sensor 240B may overlap with the second magnet unit 310B in the optical axis direction. For example, the second sensor 240B may detect the second magnet unit 310B (or the magnetic field of the second magnet unit 310B). For example, the second sensor 240B may detect the angle at which the OIS moving part 100 is tilted with respect to the first axis. In other embodiments, the second sensor 240B may not overlap with the second magnet unit 310B in the optical axis direction.

[0265] For example, the first sensor 240A and the second sensor 240B may be placed on, coupled to, or fixed to the first substrate 801 of the circuit board 800. For example, the first sensor 240A and the second sensor 240B may be electrically or electrically connected to the first substrate 801.

[0266] For example, the first sensor 240A may be located inside the hollow (or hole) of the first coil unit 230A, and the second sensor 240B may be located inside the hollow (or hole) of the second coil unit 230B. In other embodiments, the first sensor 240A may be located outside the hollow (or hole) of the first coil unit 230A, and the second sensor 240B may be located outside the hollow (or hole) of the second coil unit 230B.

[0267] For example, the first sensor 240A and the second sensor 240B may each be a Hall sensor including a first input terminal, a second input terminal, and a first output terminal and a second output terminal. For example, the first input terminal and the second input terminal and the first output terminal and the second output terminal of the first sensor 240A may be electrically or electrically connected to the first substrate 801, and the first input terminal and the second input terminal and the first output terminal and the second output terminal of the second sensor 240B may also be electrically or electrically connected to the first substrate 801.

[0268] For example, the first circuit board 801 or the control unit 830 may supply or apply a first drive signal to the first input terminal and the second input terminal of the first sensor 240A. The first sensor 240A outputs a first output signal, which can be transmitted to the first circuit board 801 or the control unit 830. The first output signal can be output from the first output terminal and the second output terminal of the first sensor 240A.

[0269] For example, the first board 801 or the control unit 830 may supply or apply a second drive signal to the first input terminal and the second input terminal of the second sensor 240B. The second sensor 240B outputs a second output signal, which can be transmitted to the first board 801 or the control unit 830. The second output signal can be output from the first output terminal and the second output terminal of the second sensor 240B.

[0270] The control unit 830 can use the first output signal of the first sensor 240A and the output signal of the second sensor 240B to control the first drive signal supplied to the first coil unit 230A and the second drive signal supplied to the second coil unit 230B.

[0271] In other embodiments, the first sensor 240A and the second sensor 240B may each be a driver IC including a Hall sensor. The description relating to embodiments in which the position sensor 170 is a driver IC including a Hall sensor may be applied or applied by analogy to embodiments in which the first sensor 240A and the second sensor 240B are driver ICs including Hall sensors.

[0272] The camera device 200 may include a magnetic body 82 positioned opposite at least one of the coil 120 and the magnet 130. For example, the magnetic body 82 may be positioned on the holder 140 or on the second substrate 802 of the circuit board 800. For example, the magnetic body 82 may correspond to, oppose, or overlap with the magnet 130 in a second direction. Also, for example, the magnetic body 82 may correspond to, oppose, or overlap with the coil 120 in a second direction. For example, the coil 120 may be positioned on the first surface of the second substrate 802 opposite to the magnet 130, and the magnetic body 82 may be positioned on the second surface of the second substrate 802 opposite to the first surface. The magnetic body 82 may be bonded, attached, or fixed to the second substrate 802 by adhesive.

[0273] The camera device 200 may include a heat dissipation member (not shown) coupled to at least one of the circuit board 800 or the sensor base 270. For example, the heat dissipation member may be positioned below the circuit board 800. For example, the heat dissipation member 280 may be positioned between the circuit board 800 and the sensor base 270. The heat dissipation member may be a plate-like member having a predetermined thickness and hardness. The heat dissipation member can also release heat generated from the heat source of the circuit board 800 to the outside, thereby improving heat dissipation efficiency. For example, the heat dissipation member may be made of a metal material or a metal plate.

[0274] Referring to Figures 10a and 10b, the housing 210 may include a cavity for housing the OIS moving part 100. For example, the housing 210 may have a shape corresponding to the OIS moving part 100, such as a holder 140 or sensor base 270, such as a polygon (e.g., a quadrilateral or octagon) or a circle (or ellipse), but is not limited to these, and can have various shapes. The housing 210 may be replaced with "base" or "frame".

[0275] The housing 210 may include a number of sides 71A to 71D corresponding to the sides 41A to 41D of the holder 140 or the sides 51A to 51D of the sensor base 270. The housing 210 may include a corner located between two adjacent sides.

[0276] Furthermore, the housing 210 may include a lower section 42 (or bottom plate) located below the side sections 71A to 71D. The lower section 42 may be connected to the underside of the side sections 71A to 71D. For example, the lower section 42 may be replaced with "bottom," "bottom surface," or "body." For example, the side sections 71A to 71D may protrude upward from the lower section 42.

[0277] The housing 210 may include a first side 71A corresponding to the first side 41A of the holder 140, which is opposite or overlapping; a second side 71B corresponding to the second side 41B of the holder 140, which is opposite or overlapping; a third side 71C corresponding to the third side 41C of the holder 140, which is opposite or overlapping; and a fourth side 71D corresponding to the fourth side 41D of the holder 140, which is opposite or overlapping.

[0278] The first side portion 71A (or first side or first outer side) of the housing 210 may be located opposite the second side portion 71B (or second side or second outer side) of the housing 210, and the third side portion 71C (or third side or third outer side) of the housing 210 may be located opposite the fourth side portion 71D (or fourth side or fourth outer side) of the housing 210. For example, the first to fourth sides 71A to 71D of the housing 210 may each be arranged parallel to any one of the corresponding side plates 302 of the cover member 300.

[0279] The housing 210 may include a step 411 located at the bottom of at least one of the side portions 71A to 71D. For example, the step 411 may project 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 with the side plate 302 of the cover member 300 in the direction of the optical axis. For example, the step 411 may be bonded to the side plate 302 of the cover member 300 by adhesive.

[0280] The housing 210 may include mounting sections 141A and 141B for arranging the magnets 310. For example, the mounting sections 141A and 141B may be groove shapes formed in the lower part 42 of the housing 210. In other embodiments, the mounting sections 141A and 141B may be through holes penetrating the lower part 42 of the housing 210.

[0281] The housing 210 may include a first mounting section 141A for arranging the first magnet unit 310A, and a second mounting section 141B for arranging the second magnet unit 310B. For example, the first mounting section 141A may be located or formed in a first region of the lower part 42 of the housing 210 adjacent to any one of the four corners of the housing 210. For example, any one of the aforementioned corners of the housing 210 may correspond to or be adjacent to a protrusion 216C of the sensor base 270.

[0282] For example, the second mounting portion 141B may be located or formed in a second region of the lower part 42 of the housing 210 adjacent to any other of the four corners of the housing 210. For example, the other corner of the housing 210 may correspond to or be adjacent to the protrusion 216D of the sensor base 270.

[0283] In other embodiments, the first and second mounting sections may be positioned in locations corresponding to the positions where the coil units 230A, 230B and the magnet units 310A, 310B are located. For example, in other embodiments, the first mounting section may be formed adjacent to a first (or second) side of the housing 210, and the second mounting section may be formed adjacent to a third (or fourth) side of the housing 210.

[0284] The magnet 310 may be positioned in or coupled to the housing 210. For example, the magnet 310 may include a first magnet unit 310A and a second magnet unit 310B positioned in the lower part 42 of the housing 210. For example, the magnet 310 may be positioned below the coil 230.

[0285]

[0286] For example, the first magnet unit 310A may be arranged to correspond to, face, or overlap with the first coil unit 230A in the optical axis direction. The second magnet unit 310B may be arranged to correspond to, face, or overlap with the second coil unit 230B in the optical axis direction.

[0287] For example, the first magnet unit 310A and the second magnet unit 310B may be offset in the first axial direction (or parallel to the first axis) or the second axial direction (or parallel to the second axis). For example, when viewed from above or in the optical axis direction, the first magnet unit 310A and the second magnet unit 310B may be positioned in the housing 210 such that they do not overlap each other in the direction parallel to the first axis or parallel to the second axis. For example, the first magnet unit 310A and the second magnet unit 310B may be positioned in the lower part 42 of the housing 210 such that they do not overlap each other in the direction parallel to the first axis or parallel to the second axis.

[0288] In other embodiments, the first and second magnet units may be offset from each other in the first horizontal direction (or X-axis direction) or the second horizontal direction (or Y-axis direction). For example, in other embodiments, when viewed from above, the first magnet unit may be positioned to coincide with the first horizontal axis (or X-axis), and the second magnet unit may be positioned to coincide with the second horizontal axis (or Y-axis).

[0289] Each of the first magnet unit 310A and the second magnet unit 310B may be a two-pole magnet having one north pole and one south pole. For example, each of the first magnet unit 310A and the second magnet unit 310B may be a magnet divided or arranged as a north pole and a south pole 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).

[0290] For example, the first surface of the magnet 310 facing the coil 230 in the optical axis direction may be a south pole (or north pole). Also, the second surface of the magnet 310 opposite to the first surface may be a north pole (or south pole).

[0291] In the embodiments shown in Figures 2a and 2b, the coil 230 and the magnet 310 face each other in the optical axis direction, but in other embodiments, the coil 230 and the magnet 310 may be arranged to face each other in a direction perpendicular to the optical axis direction (e.g., a second or third direction). In this case, the magnet units 310A and 310B may be arranged on two adjacent sides of the housing 210 among the sides 71A to 71D, and the coil units 230A and 230B may be arranged on the movable part (e.g., holder 140) to face the magnet units 310A and 310B in a direction perpendicular to the optical axis direction. In this case, the circuit board 800 is connected to the first board 801 and may include an additional board (or extension region) for which the coil units 230A and 230B are arranged. In yet another embodiment, the position sensor 240 may be arranged together with the coil 230 on two sides of the housing 210, may be arranged on or coupled to an additional board (or extension region) of the circuit board 800, and may be electrically connected. In another embodiment, the magnet units 310A and 310B may be positioned in two adjacent corners of the housing 210.

[0292] Referring to Figures 10a and 16a, the camera device 200 may include a yoke 380 positioned on the magnet 310. The yoke 380 can reduce or suppress the leakage flux of the magnet 310, increase the electromagnetic force between the magnet 310 and the coil 230, and improve the driving force for OIS drive. The yoke 380 may be made of a material that is attracted to magnetic materials. For example, the yoke 380 may be made of a metallic material. Or, for example, the yoke 380 may be made of a magnetic metallic material. Or, for example, the yoke 380 may be a magnetic material, i.e., a magnet.

[0293] The yoke 380 may be positioned in the housing 210. For example, the yoke 380 may be positioned between the housing 210 and the magnet 310. For example, the yoke 380 may be positioned within the mounting portions 141A and 141B of the housing 210. For example, the yoke 380 may face the magnet 310 or the coil 230. For example, the yoke 380 may be positioned on the second surface (e.g., the bottom surface) of the magnet 310, opposite the first surface (e.g., the top surface) of the magnet 310 facing the coil 230. The yoke 380 may be in contact with or attached to the magnet 310. For example, the yoke 380 may be attracted to the magnet 310.

[0294] For example, the yoke 380 may be coupled to the housing 210 by an insert injection molding method. When the yoke 380 and the housing 210 are coupled by an insert injection molding method, at least a portion of the yoke 380 is located inside the housing 210, and at least another portion of the yoke 380 is exposed from the housing 210 and may be coupled to or attached to the magnet 310.

[0295] In other embodiments, the yoke 380 may be positioned within mounting portions 141A and 141B of the housing 210 by adhesive. The yoke 380 may include a first yoke 380A positioned on the first magnet unit 310A and a second yoke 380B positioned on the second magnet unit 310B. For example, the first yoke 380A may be positioned within the first mounting portion 141A of the housing 210, and the second yoke 380B may be positioned within the second mounting portion 141B of the housing 210. Since the magnet 310 can be attracted to the yoke 380, the ease of assembly between the magnet 310 and the housing 210 can be improved or the assembly between the magnet 310 and the housing 210 can be facilitated when assembling the magnet 310 to the housing 210.

[0296] In other embodiments, the first magnet unit 310A and the second magnet unit 310B may each be magnets divided or arranged as one north pole and one south pole in a direction perpendicular to the optical axis. In yet another embodiment, the first magnet unit 310A and the second magnet unit 310B may each be magnets containing two north poles and two south poles. An electromagnetic force may be generated between the first magnet unit 310A and the second magnet unit 310B and the first coil unit 230A and the second coil unit 230B, and the generated electromagnetic force allows the OIS moving part to tilt along the first axis or the second axis.

[0297] In other embodiments, the positions of the magnet 310 and the coil 230 in Figure 6 may be swapped. For example, the magnet 310 may be located on the movable part 100 (e.g., the sensor base 270), and the coil 230 may be located on the fixed part (e.g., the housing 210). In this case, the yoke in Figure 16a may be located on the sensor base 270. For example, the yoke may be located on the upper surface of the magnet 310. Camera devices according to other embodiments may include a circuit board ("second circuit board") that is provided separately from the circuit board 800 ("first circuit board") and located on the fixed part (e.g., the housing 210). The coil 230 may be located on or coupled to the second circuit board. The coil 230 may be electrically or electrically connected to the second circuit board. For example, the second circuit board may be located below the housing 210. A coil 230 may be placed in the mounting portion 141 of the housing 140, in which case the mounting portion 141 may be a through hole penetrating the lower part 42 of the housing 140. The position sensor 240 may be placed on or coupled to the second circuit board. For example, the first sensor 240A may be placed in the hollow of the first coil unit 230A, and the second sensor 240B may be placed in the hollow of the second coil unit 230B. The position sensor 240 may be electrically or electrically connected to the second circuit board. Camera devices according to other embodiments may include a control unit (referred to as the "second control unit") separate from the control unit 830 (referred to as the "first control unit"). The second control unit may be placed on the second circuit board. The second control unit may be electrically or electrically connected to the second circuit board. For example, the second control unit may be a driver IC. For example, the second control unit may be placed on, coupled to, or fixed to the first surface of the second circuit board. The first surface of the second circuit board may be the surface facing the magnet 310 or the OIS moving part, such as the lens module. The second coil 230 may be arranged on the first surface of the second circuit board. The second control unit may be electrically or electrically connected to the coil 230. It can supply a drive signal to the coil 230. For example, the second control unit may be electrically connected to 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.The second control unit may be electrically or electrically connected to the position sensor 240. For example, the second control unit can supply power or a drive signal to the position sensor 240. For example, the second control unit can supply power or a drive signal to the first sensor 240A and the second sensor 240B, respectively. The control unit 835 can receive the output signal of the position sensor 240 and control the drive signal (e.g., drive current) supplied to the coil 230 using the output signal of the position sensor 240. For example, the second control unit can receive the output signal of the first sensor 240A and control the first drive signal (e.g., first drive current) supplied to the first coil unit 230A using the output signal of the first sensor 240A. The second control unit can also receive the output signal of the second sensor 240B and control the second drive signal (e.g., second drive current) supplied to the second coil unit 230B using the output signal of the second sensor 240B. The second circuit board may include terminals. The terminal section may include multiple terminals. For example, multiple terminals on the second circuit board may be exposed from the side plate 302 of the cover member 300. At least one of the multiple terminals may be electrically or electrically connected to the second control unit.

[0298] Furthermore, the second circuit board according to other embodiments may include a first board disposed in the housing 210, and a second board (or extension board) extending from the first board. Connectors may be provided on the second board. Terminals may be omitted in the second circuit board according to other embodiments. The second control unit may be electrically or electrically connected to the connector of the second circuit board. Alternatively, in other embodiments, the second control unit may be omitted, and the coil 230 or position sensor 240 may be electrically or electrically connected to the connector of the second circuit board. The connector of the second circuit board may be coupled or connected to other connectors or external devices outside the camera device 200. The connector of the second circuit board that is coupled to other external connectors may correspond to a fixed part that does not operate when the OIS is driven.

[0299] The housing 210 may include a housing portion 49A for housing or arranging the magnetic material 31. The housing portion 49A may be located or formed in the lower part 42 of the housing 210. The housing portion 49A may be located or formed on the upper surface of the lower part 42 of the housing 210. For example, the housing portion 49A may be a groove recessed from the upper surface of the lower part 42 of the housing 210. The housing portion 49A may have a shape corresponding to the magnetic material 31, for example, rectangular or circular. For example, the housing portion 49A of the housing 210 may correspond to, face, or overlap with the support member 64 or the magnetic material 33 in the optical axis direction.

[0300] Referring to Figure 10b, the housing 210 may include a mounting portion 69 on which at least a portion of the tilt guide portion 60 is positioned or for housing at least a portion of the tilt guide portion 60. For example, the mounting portion 69 may be a groove recessed from the bottom surface of the housing 210 or the top surface of the lower portion 42.

[0301] For example, the mounting portion 69 may have a shape that corresponds to or matches the tilt guide portion 60. For example, the mounting portion 69 may include a bottom surface 69A that is stepped with the upper surface of the lower part 42 of the housing 210 in the optical axis direction, and a side surface 69B that connects the bottom surface 69A and the upper surface of the lower part 42. The side surface 69B may be described as a "partition" or "side wall". For example, the bottom surface 69A of the mounting portion 69 may be located lower than the upper surface of the lower part 42 of the housing 210. In other embodiments, the mounting portion 69 may be omitted.

[0302] Referring to Figures 4a, 4b, 11, and 12, the upper surface of the lower part 42 of the housing 210 has a mounting portion 69 formed for inserting or positioning at least a portion of the tilt guide portion 60, so the lower part 42 of the housing 210 may include a partition wall 69B (or guide portion) positioned around the tilt guide portion 60. The tilt guide portion 60 may be separated from the partition wall 69B of the housing 210, and the partition wall 69B may be positioned to surround the tilt guide portion 60. The partition wall 272 of the housing 210 can prevent the tilt guide portion 60 from detaching or falling out of the housing 210. In other embodiments, at least a portion of the tilt guide portion 60 may be in contact with the partition wall 69B of the housing 210.

[0303] The housing 210 may include a portion ("first portion 49") that is positioned between the magnetic material 31 and the magnetic material 33. For example, the housing 210 may include a coupling portion 49 that connects to the magnetic material 31. The coupling portion 49 may be positioned between the magnetic material 31 and the magnetic material 33.

[0304] For example, the coupling portion 49 may be part of the lower portion 42 of the housing 210. For example, the coupling portion 49 may be a projection or protrusion that protrudes from the lower portion 42 of the housing 140. For example, the coupling portion 49 may protrude from the upper surface of the lower portion 42 of the housing 210. Or, for example, the coupling portion 49 may protrude from the bottom surface 69A of the mounting portion 69 of the housing 210. For example, the protruding length of the coupling portion 49 of the housing 210 may be greater than the depth of the mounting portion 69 of the housing 210. For example, the protruding length of the coupling portion 49 may be the distance (or shortest distance) from the bottom surface 69A of the mounting portion 69 to the top surface (or uppermost end) of the coupling portion 49. Also, the depth of the mounting portion 69 may be the distance (or shortest distance) from the top surface of the lower portion 42 of the housing 210 to the bottom surface 69A of the mounting portion 69. In other embodiments, for example, the protruding length of the coupling portion 49 may be the same as or less than the depth of the mounting portion 69. For example, the joint portion 49 may have a shape that corresponds to or matches the opening 60A of the tilt guide portion 60.

[0305] For example, the coupling portion 49 of the housing 210 may correspond to, face, or overlap with the opening 60A of the tilt guide portion 60 in the optical axis direction. For example, at least a portion of the coupling portion 49 of the housing 210 may be located within the opening 60A of the tilt guide portion 60. Since at least a portion of the coupling portion 49 of the housing 210 is located within the opening 60A of the tilt guide portion 60, the separation distance between the coupling portion 49 and the magnetic material 33 can be shortened, thereby increasing the repulsive force between the magnetic material 31 located in the coupling portion 49 and the magnetic material 33 located in the OIS moving portion, and enabling stable support of the OIS moving portion.

[0306] For example, the housing portion 49A may be located in or formed in the joint portion 49 of the housing 210. For example, the housing portion 49A may be a groove recessed from the upper surface of the joint portion 49 of the housing 210.

[0307] For example, when viewed from the direction of the optical axis or from above, the coupling portion 49 may be positioned between grooves 55A and 55B of the housing 210. For example, the coupling portion 49 may be positioned between protrusions 66A and 66B of the tilt guide portion 60. For example, the coupling portion 49 (or magnetic material 31) may overlap with the protrusions 66A and 66B of the tilt guide portion 60 in a direction perpendicular to the optical axis.

[0308] For example, at least a portion of the first magnet unit 310A may correspond to, face, or overlap with the tilt guide portion 60 in a direction parallel to the first axis. Also, at least a portion of the second magnet unit 310B may correspond to, face, or overlap with the tilt guide portion 60 in a direction parallel to the second axis.

[0309] The housing 210 may include grooves 55 in which at least a portion of the projections 66 of the tilt guide portion 60 are positioned or to accommodate at least a portion of the projections 66. The grooves 55 of the housing 210 may be formed on the upper surface of the lower portion 42 of the housing 210. For example, the grooves 55 may be formed recessed from the upper surface of the lower portion 42 of the housing 210. For example, the grooves 55 may be formed on the bottom surface 69A of the mounting portion 69 of the housing 210. For example, the grooves 55 may be formed recessed further from the bottom surface 69A of the mounting portion 69 of the housing 210. The number of grooves 55 in the housing 210 may be the same as the number of projections 66 of the tilt guide portion 60.

[0310] For example, groove 55 may include two grooves 55A and 55B that are spaced apart from each other. For example, the two grooves 55A and 55B may be spaced apart from each other in the second axial direction. For example, the direction in which the two grooves 55A and 55B of the housing 210 are spaced apart and the direction in which the two grooves 29A and 29B of the sensor base 270 are spaced apart may intersect or be perpendicular to each other. For example, the housing 49A may be located between the two grooves 55A and 55B of the housing 210.

[0311] The groove 55 of the housing 210 may contact the projection 66 of the tilt guide portion 60 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 identical to each other. In other embodiments, at least one of the inclined surfaces of the groove 55 may have a different shape from the other inclined surfaces.

[0312] The housing 210 may include an opening 18 or “groove” through which at least a portion of the moving module (or tilt module) is positioned or passed. For example, the housing 210 may include an opening 18 through which at least a portion of the sensor base 270 is positioned or passed. The opening 18 may be formed in the lower part 42 of the fixed portion (e.g., the housing 210).

[0313] Referring to Figure 13, the fixed portion (e.g., the housing 210) may include a groove 89 formed on the lower surface of the lower part 42 of the fixed portion. The groove 89 may be recessed from the lower surface of the lower part 42 of the housing 210. For example, the groove 89 may include a bottom surface 89A and a side surface 89B located between the bottom surface 89A and the lower surface of the lower part 42. For example, the bottom surface 89A may be the lower surface of the joint 49. For example, the opening 18 may be formed in the bottom surface 89A of the groove 89. At least a portion of the support member 64 may be positioned within the groove 89 of the housing 210. For example, referring to Figures 4f and 14b, the end of the extension 217 of the sensor base 270 may be positioned higher than the lower surface of the lower part 42 of the housing 210. Also, the lower surface of the support member 64 may be positioned higher than the lower surface of the lower part 42 of the housing 210.

[0314] For the support member 64 to be positioned in the groove 89, the size of the groove 89 may be larger than the size of the support member 64 when viewed from below. Alternatively, the area of ​​the upper surface of the support member 64 may be smaller than the total area of ​​the opening 18 of the fixed part (housing 210). In other embodiments, the groove 89 may be omitted.

[0315] The opening 18 may include a through-hole that penetrates the housing 210 in the optical axis direction. For example, the opening 18 may include a hole or through-hole that penetrates the lower part 42 of the housing 210. For example, the opening 18 may be located within the mounting portion 69. For example, the opening 18 may be formed on the bottom surface 69A of the mounting portion 69. The opening 18 may include a hole that penetrates the bottom surface 69A of the mounting portion 69.

[0316] For example, the opening 18 may be open to the lower surface of the lower part 42 of the housing 210. For example, the opening 18 may include a first opening 18A and a second opening 18B.

[0317] For example, when viewed from above, the joint 49 may be used as the reference point, and the joint may include a first opening 18A (or first hole) located on one side of the joint 49 (for example, the right side (or upper side)) and a second opening 18B (or second hole) located on the other side of the joint 49 (for example, the left side (or lower side)).

[0318] In the embodiments of Figures 4b, 10a, and 10b, the first opening 18A and the second opening 18B are in communication with each other, but in other embodiments, the first and second openings may be separated or separated from each other via a coupling portion 49. The shapes of the first opening 18A and the second opening 18B may correspond to or be identical to the shape of the extension portion 217 of the sensor base 270. The opening 18 of the housing 210 can serve as an assembly passage for connecting the support member 64 to the extension portion 217 of the sensor base 270. Therefore, the size of the opening 18, for example, its diameter, may be larger than the size of the support member 64. In this case, the size of the support member 64 may be the length of the support member 64 in a direction perpendicular to the optical axis (horizontal or vertical length).

[0319] The movable module (or tilt module) may be positioned within the opening 18 of the housing 210, or may include at least a portion (or “extension”) that passes through the opening 18 of the housing 210. At least a portion (or extension) of the movable module (or tilt module) may be connected to or coupled with the magnetic material 33. For example, at least a portion (or extension) of the movable module (or tilt module) may be connected to or coupled with the support member 64.

[0320] Referring to Figure 7d, for example, the sensor base 270 may be positioned within the opening 18 of the housing 210, or may include at least a portion (or “extension”) 217 ​​that passes through the opening 18 of the housing 210. The extension 217 of the sensor base 270 may extend or protrude from the lower or lower surface of the sensor base 270. The extension 217 may be replaced with "projection," "guide," "connecting guide," or "connecting part."

[0321] The extension 217 can be connected to or coupled with the magnetic material 33. For example, the extension 217 can be connected to or coupled with the support member 64. For example, the sensor base 217 may include at least one projection 219 for coupling with the support member 64, and the support member 64 may include at least one groove 8, hole or through-hole for coupling with the projection 219 of the sensor base 270. For example, the groove 8 may be formed on the upper surface of the support member 64.

[0322] The sensor base 270 may include two protrusions 219A and 219B, but in other embodiments, the number of protrusions on the sensor base 270 may be one or three or more. The groove 8 of the support member 64 may include two grooves 8A and 8B, but in other embodiments, the number of grooves 8 of the support member 64 may be the same as the number of protrusions on the sensor base 270. In other embodiments, the extension 217 of the sensor base 270 may include a protrusion, and the support member 64 may include grooves, holes, or through-holes that correspond to or connect to the protrusions of the extension 217.

[0323] At least a portion of the extension 217 may be positioned within the opening 18 of the housing 210. At least a portion of the extension 217 may be exposed from the opening 18 of the housing 210.

[0324] For example, the extension 217 may include a first extension 217A corresponding to, facing, or overlapping with the first opening 18A of the housing 210, and a second extension 217B corresponding to, facing, or overlapping with the second opening 18B of the housing 210. For example, at least a portion of the first extension 217A may be located within or passing through the first opening 18A of the housing 210. For example, at least a portion of the second extension 217B may be located within or passing through the second opening 18B of the housing 210.

[0325] At least a portion of the extension 217 may be positioned to surround at least a portion of the projections 219A and 219B. For example, at least a portion of the extension 217 may include guide portions 9A and 9B that surround at least a portion of the projections 219A and 219B. For example, the first extension 217A may include a first guide portion 9A that surrounds at least a portion of the first projection 219A. The second extension 217B may include a second guide portion 9B that surrounds at least a portion of the second projection 219B. For example, the guide portions 9A and 9B may be arranged to surround at least a portion of the support member 64. For example, the first guide portion 9A may be arranged to surround a portion of the support member 64, and the second guide portion 9B may be arranged to surround another portion of the support member 64. The guide portions 9A and 9B can guide the connection between the support member 64 and the extension 217 of the sensor base 270. In other embodiments, the extension 217 may include a groove for positioning or resting at least a portion of the support member 64.

[0326] The housing 210 may include a projection 215 that protrudes in a direction perpendicular to the optical axis. For example, the protrusion 215 may protrude from the side of the housing 210.

[0327] For example, the projection 215 may project from the outer surface of the fourth side portion 71D of the housing 210. For example, the projection 215 may be configured such that at least a portion of the fourth side portion 71D passes through the optical axis and projects in a direction parallel to a straight line perpendicular to the optical axis. For example, the projection 215 may include a groove 16A (or cavity) for which at least a portion of the fourth substrate 804 is positioned or accommodated. For example, the groove 16A of the projection 215 may include an opening that is open upward.

[0328] Referring to Figure 10a, coupling grooves 215A and 215B may be formed in the groove 16A of the projection 215 for insertion, coupling, or fixing of the movement-restricting portion 80. For example, coupling grooves 215A and 215B may be formed on two opposing inner surfaces of the groove 16A of the projection 215. For example, coupling grooves 215A and 215B may extend in the direction of the optical axis. For example, coupling grooves 215A and 215B may include openings that open to the upper surface of the projection 215 in order to easily insert or couple the movement-restricting portion 80 from above.

[0329] 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. This configuration makes it easy to secure space for the circuit board 800 to extend outward, enabling the realization of a compact camera device.

[0330] The camera device 200 may include a movement-restricting unit 80 that is coupled to at least a portion of the housing 210. The movement-restricting unit 80 can restrict the movement or motion of at least a portion of the fourth substrate 804, thereby preventing deformation of at least a portion of the shape of the fourth substrate 804.

[0331] Referring to Figures 7c, 8, and 11a, the fourth substrate 804 of the circuit board 800 may include a first portion 804A (or "first region") 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, at least one of the first portion 804A and the second portion 804B may be omitted.

[0332] 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 the opposite direction to the first portion 804A.

[0333] 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 angular, but for example, the first portion 804A and the second portion 804B may be right angles. In other embodiments, the first bent portion 804D and the second bent portion 804E may be rounded. In other embodiments, the interior angle between the first portion 804A and the second portion 804B may be acute or obtuse.

[0334] The first bent portion 804D and the second bent portion 804E prevent the length of the camera device 200 in the direction perpendicular to the optical axis from increasing. 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), it is possible to prevent an increase in the length of the camera device 200 in the optical axis direction, thereby enabling miniaturization of the camera device.

[0335] For example, the third portion 804C may be a plate or planar shape perpendicular to the optical axis. For example, the third portion 804C may include a meandering or bent shape. For example, the third portion 804C may include at least one bent or curved region. For example, the bent or curved region of the third portion 804C may be bent in a second or third direction perpendicular to the optical axis. Alternatively, the bent 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.

[0336] For example, the third portion 804C may be separated from the housing 210. For example, the third portion 804C may be separated from the projection 215 of the housing 210. In other embodiments, for example, at least a portion of the third portion 804C may be in contact with the projection 215 of the housing 210.

[0337] At least a portion of the second portion 804B of the fourth substrate 804 may be positioned within the projection 215 of the housing 210. At least a portion of the second portion 804B of the fourth substrate 804 may be positioned within the groove 16A of the projection 215 of the housing 210. For example, at least a portion of the first portion 804A of the fourth substrate 804 may be positioned within the groove 16A of the protrusion 215 of the housing 140. The third portion 804B 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. The lower surface of the third portion 804B of the fourth substrate 804 may be located above the upper surface of the protrusion 215 of the housing 210.

[0338] Referring to Figure 7a, the sensor base 270 may include a groove 273 formed at a location where the fourth substrate 804 and the first substrate 801 meet or connect, i.e., at a location corresponding to the first portion 804A of the fourth substrate 804. The groove 273 may be positioned adjacent to or in contact with the outer surface of the fourth side portion 51D of the sensor base 270 on which the fourth substrate 804 is placed. The groove 273 can serve to prevent the first portion 804A of the fourth substrate 804 from being damaged by friction with the sensor base 270.

[0339] Connector 805 can be coupled or connected to other external connectors or external devices on the camera device 200. Connector 805 that is coupled to other external connectors may correspond to a fixed part that does not move when the OIS is driven. The third portion 804C of the fourth substrate 804 includes at least one bent or curved region and can therefore elastically support the camera device 200 or the OIS moving part and can play a role in mitigating external shocks. In other words, the third portion 804C of the fourth substrate 804 can play a role in mitigating shocks. Furthermore, since the third portion 804C of the fourth substrate 804 can play a role in elastically supporting the OIS moving part 100, the driving force or driving power required when the OIS is driven can be reduced.

[0340] Referring to Figures 11a and 11b, the camera device 200 may include reinforcing members 70, 70-1 that are positioned, coupled, or attached to at least a portion of the fourth substrate 804. The reinforcing members 70, 70-1 may be positioned, coupled, or attached to at least one of the first portion 804A and the second portion 804B of the fourth substrate 804. For example, the reinforcing members 70, 70-1 may be positioned, coupled, or attached to at least a portion of the first portion 804A and at least a portion of the second portion 804B of the fourth substrate 804.

[0341] For example, reinforcing members 70, 70-1 may be positioned, joined, 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, reinforcing members 70, 70-1 may include a first region 70A positioned, joined, or attached to the first portion 804A, and a second region 70B positioned, joined, 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.

[0342] For example, the area of ​​the second region 70B may be larger than the area of ​​the first region 70A. In other embodiments, they may be the same, or the area of ​​the former 70B may be smaller than the area of ​​the latter 70A.

[0343] For example, reinforcing members 70, 70-1 can be separated from the third portion 804C of the fourth substrate 804. For example, the second region 70B of reinforcing members 70, 70-1 can be separated from the third portion 804C of the fourth substrate 804. In other embodiments, at least a portion of the second region 70B of reinforcing members 70, 70-1 can be in contact with the third portion 804C of the fourth substrate 804.

[0344] In other embodiments, the reinforcing members 70, 70-1 may be positioned, bonded, or attached to the upper surface of the first portion 804A and the upper surface of the second portion 804B of the fourth substrate 804. For example, in other embodiments, the reinforcing members 70, 70-1 may include a first region positioned on the upper surface of the first portion 804A and a second region positioned on the upper surface of the second portion 804B of the fourth substrate 804.

[0345] In other embodiments, the reinforcing members 70, 70-1 may be positioned, joined, 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 other embodiments, the reinforcing members 70, 70-1 may be positioned, joined, or attached to the second portion 804B and the third portion 804C of the fourth substrate 804. For example, the reinforcing members 70, 70-1 may include a first region positioned, joined, or attached to the second portion 804B of the fourth substrate 804 and a second region positioned, joined, or attached to the third portion 804C, with a bent portion formed between the first and second regions. The first region of the reinforcing members 70, 70-1 may be positioned on the lower (or upper) surface of the second portion 804B, and the second region of the reinforcing members 70, 70-1 may be positioned on the lower (or upper) surface of the third portion 804C.

[0346] The reinforcing members 70 and 70-1 can prevent the fourth substrate 804 from being damaged, deformed, or broken by impact or external force. Furthermore, the reinforcing members 70 and 70-1 can play a role in preventing the fourth substrate 804 from being subjected to force due to the tilt of the OIS moving part 100, thereby preventing its shape from being deformed and then restored. For example, the reinforcing members 70 and 70-1 may include at least one of a metallic material or an injection-molded material.

[0347] For example, the reinforcing members 70, 70-1 may be positioned inside the groove 16A of the projection 215 of the housing 210. For example, the reinforcing members 70, 70-1 may be in contact with the groove 16A of the projection 215 of the housing 210 in at least part. For example, the reinforcing members 70, 70-1 may not be bonded to the housing 210 (e.g., the projection 215). In other embodiments, for example, the reinforcing members 70, 70-1 may be bonded to the housing 210 (e.g., the projection 215) by adhesive.

[0348] The reinforcing member 70 in Figure 11a may include an opening 73. The opening 73 of the reinforcing member 70 may open up or expose at least a portion of the fourth substrate 804 of the circuit board 800. For example, the opening 73 may open up or expose at least a portion of the first portion 804A (or "first region") and the second portion 804B (or "second region") of the fourth substrate 804. The opening 73 of the reinforcing member 70 may be a hole, a through hole, or a hollow portion.

[0349] The opening 73 may be formed in at least one of the first region 70A and the second region 70B of the reinforcing member 70. For example, the opening 73 may be formed in both the first region 70A and the second region 70B of the reinforcing member 70. The opening 73 may also open or expose at least a portion of the first bent portion 804D. In other embodiments, the opening 73 may be formed in only one of the first region 70A and the second region 70B of the reinforcing member 70. In other embodiments, the opening 73 may not expose the first bent portion 804D.

[0350] The opening 73 reduces the elastic modulus of the second substrate 802 of the circuit board 800 that is coupled to the reinforcing member 70, thereby facilitating the movement of the OIS moving part during OIS driving. In other words, the opening 73 reduces the elastic force of the circuit board 800, for example, the second substrate 802, that supports the OIS moving part, thereby enabling OIS driving with a small driving force and reducing power consumption. In this case, the driving force may be the force due to the interaction between the coil 230 and the magnet 310.

[0351] Referring to Figures 1, 10a, and 10b, the movement restraint 80 can be coupled to the protrusion 215 of the housing 210. For example, the movement restraint 80 can be coupled to coupling grooves 215A and 215B of the protrusion 215 of the housing 210.

[0352] Referring to Figure 3, at least a portion of the second portion 804B of the fourth substrate 804 may be positioned between the movement-restricting portion 80 and the inner surface of the protrusion 215 of the housing 210. For example, at least a portion of the reinforcing member 70 may be positioned between the movement-restricting portion 80 and the inner surface of the protrusion 215 of the housing 210. The movement-restricting portion 80 may be separated from the circuit board 800 in a second direction (X-axis direction) or a third direction (Y-axis direction). For example, the movement-restricting portion 80 may be positioned separated from the circuit board 800 in the optical axis direction or in a direction perpendicular to the optical axis direction. That is, the movement-restricting portion 80 may play a role in maintaining the shape of the bent portions 804D, 804E of the flexible substrate fourth substrate 804. For example, the movement-restricting portion 80 may be an injection-molded product made of a non-magnetic material or resin. In other embodiments, the movement-restricting portion 80 may be in contact with at least a portion of the fourth substrate 804 of the circuit board 800.

[0353] The movement-restricting unit 80 can restrict the movement or motion of at least a portion of the second portion 804B of the fourth substrate 804, which is positioned within the groove 16A of the protrusion 215, thereby preventing or suppressing the second portion 804B from deviating outside the groove 16A of the protrusion 215. This prevents or suppresses the OIS movement unit from being affected by the restoring force of the fourth substrate 804 during OIS driving, enabling accurate OIS driving and improving the reliability of OIS driving. The movement-restricting unit 80 may be replaced with the term "clamp".

[0354] The cover member 300 may form a housing space together with the housing 210, and the OIS moving part may be arranged within the housing space. For example, the cover member 300 may be a box shape with an open bottom. For example, the cover member 300 may include a top plate 301 and a side plate 302 connected to the top plate 301.

[0355] The lower end of the side plate 302 of the cover member 300 can be connected to the housing 210. The shape of the top plate 301 of the cover member 300 can be polygonal (e.g., quadrilateral 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 that penetrates the top plate 301 of the cover member 300 in the direction of the optical axis. For example, the cover member 300 may have multiple side plates. The material of the cover member 300 may be non-magnetic. In other embodiments, the cover member 300 may also be magnetic. For example, the material of the cover member 300 may be an injection molded product such as resin or a metal material.

[0356] Referring to Figures 1 and 2a, the cover member 300 may include an opening 304 positioned or formed in the side plate 302 to avoid spatial interference with the protrusion 215 of the housing 210. For example, the protrusion 216 of the housing 210 may pass through the opening 304 of the cover member 300 and protrude from the side plate 302 of the cover member 300.

[0357] The cover member 300 is positioned above the opening 304 and may include a projection 305 that protrudes from the side plate 302. For example, the projection 305 may be plate-shaped. For example, the projection 305 of the cover member 300 may be positioned on a projection 215 of the housing 210. For example, the projection 305 may be positioned above the groove 16A of the projection 215 of the housing 210. For example, the projection 305 may be positioned above the movement-restricting portion 80. For example, the projection 305 may overlap with the movement-restricting portion 80 in the optical axis direction. Also, for example, the projection 305 may overlap with the first portion 804A of the fourth substrate 804 in the optical axis direction. The projection 305 can suppress or prevent the movement-restricting portion 80 from detaching and can protect the movement-restricting portion 80 and the fourth substrate 804 from impact.

[0358] Referring to Figure 4g, the cover member 300 may include a projection 311 protruding from the upper plate 301. In this case, the projection 311 of the cover member 300 may protrude from the inner surface of the upper plate 301 of the cover member 300 toward the bobbin 110 or the rolling member 21. For example, the projection 311 of the cover member 300 may face or overlap with the housing portion 116 of the bobbin 110 in the optical axis direction. At least a portion of the projection 311 of the cover member 300 may be inserted into or positioned within the housing portion 116 of the bobbin 110. The projection 311 of the cover member 300 may be positioned on the rolling member 21.

[0359] For example, the cover member 300 may include a first projection 311A ​​that corresponds to, opposes or overlaps with, the first rolling member 21A or the first housing portion 116A of the bobbin 110. For example, the cover member 300 may include a second projection 311B that corresponds to, opposes or overlaps with, the second rolling member 21B or the second housing portion 116B of the bobbin 110. For example, the projection 311 of the cover member 300 may include a groove that is recessed from the upper surface of the upper plate 301 of the cover member 300. In other embodiments, the projection 311 of the cover member 300 may not include a groove. By providing the projection 311 on the cover member 300, the embodiment can prevent the rolling member 21 from detaching from the housing portion 116 of the bobbin 110. The projection 311 of the cover member 300 can also act as a stopper to prevent the bobbin 110 from moving further within a limited range in the upward direction.

[0360] Next, I will explain the support structure.

[0361] A support section may be positioned between the fixed section and the OIS moving section 100. The support section may be positioned between the sensor base 270 and the housing 210 and be able to support the sensor base 270 relative to the housing 210. The support section may include a tilt guide section 60 positioned between the OIS moving section (e.g., the sensor base 270) and the fixed section (e.g., the housing 210). The tilt guide section 60 can guide the tilt of the OIS moving section 100.

[0362] The tilt guide section 60 can be replaced with a drive plate, mover, mover plate, drive board, plate, rotating board, tilting board, moving plate, or support plate.

[0363] The tilt guide section 60 is tiltable or rotatable by a predetermined angle with respect to the first or second axis. For example, the tilt guide section 60 may be positioned between the lower part (or lower surface) of the sensor base 270 and the lower part 42 of the housing 210. For example, at least a portion of the tilt guide section 60 may be positioned within the mounting section 69 of the housing 210. Because the tilt guide section 60 is positioned within the mounting section 69 of the housing 210, the length or height of the camera device 200 in the optical axis direction can be reduced.

[0364] Referring to Figures 4b, 9a, and 12, the tilt guide portion 60 may be plate-shaped. The tilt guide portion 60 may include a body. The body may be replaced with "main body" or "plate portion". When viewed from above, the shape of the body of the tilt guide portion 60 may be polygonal (e.g., quadrilateral), circular, or elliptical. When viewed from above, the shape of the body of the tilt guide portion 60 is quadrilateral, and the corners (or edges) of the body may be rounded.

[0365] For example, the length of the tilt guide section 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 tilt guide section 60 in the direction of the optical axis.

[0366] The tilt guide section 60 may include a first guide member positioned on a first surface (or top surface) 6A facing the OIS moving section (e.g., sensor base 270), and a second guide member positioned on a second surface (or bottom surface) 6B facing the fixed section (e.g., housing 210).

[0367] There may be at least one first guide member and at least one second guide member. For example, a first axis may be formed by the first guide members and a second axis may be formed by the second guide members. For example, the first guide members may include a plurality of first guide members spaced apart in a direction parallel to the first axis. The second guide members may include a plurality of second guide members spaced apart in a direction parallel to the second axis. For example, a first axis may be formed by a plurality of first guide members and a second axis may be formed by a plurality of second guide members.

[0368] The first guide member may be a "projection," "protrusion," "ball member," or "ball," and the second guide member may be a "projection," "protrusion," "ball member," or "ball."

[0369] Referring to Figures 9a and 9b, the tilt guide portion 60 may include a first projection 65 that is coupled to or in contact with the sensor base 270, and a second projection 66 that is coupled to or in contact with the housing 210. The first projection 65 may be located on a first surface 6A (e.g., the top surface) of the tilt guide portion 60, and the second projection 66 may be located on a second surface 6B (or bottom surface) opposite to the first surface 6A of the tilt guide portion 60. For example, the first projection 65 may protrude from the first surface 6A (e.g., the top surface) of the tilt guide portion 60, and the second projection 66 may protrude from the second surface 6B (e.g., the bottom surface) of the tilt guide portion 60.

[0370] The first projection 65 may be replaced with "upper projection (or anterior projection)" or "first protrusion," and the second projection 66 may be replaced with "lower projection (or posterior projection)" or "second protrusion." The number of first projections 65 and second projections 66 may be one, two, or three or more, respectively.

[0371] At least a portion of the first projection 65 may be positioned within the groove 29 of the sensor base 270. The first projection 65 may include at least two projections 65A, 65B. For example, the first-1 projection 65A and the first-2 projection 65B may be spaced apart in the first axial direction. Each of the two projections 65A, 65B may be inserted into and positioned in the corresponding first groove 29A and second groove 29B of the sensor base 270. In other embodiments, the two projections 65A, 65B may be spaced apart in the first horizontal direction or in the X-axis direction.

[0372] At least a portion of the second projection 66 may be positioned within the groove 55 of the housing 210.

[0373] The second projection 66 may include at least two projections 66A, 66B. For example, the second-first projection 66A and the second-second projection 66B may be spaced apart in the second axial direction. Each of the two projections 66A, 66B may be inserted into and positioned in the corresponding first groove 55A and second groove 55B of the housing 210. In other embodiments, the two projections 66A, 66B may be spaced apart in the second horizontal direction or the Y-axis direction.

[0374] In other embodiments, the two protrusions 65A and 65B of the tilt guide portion 60 may be spaced apart in the second axial direction, the first groove 29A and the second groove 29B of the sensor base 270 may be spaced apart in the second axial direction, the two protrusions 66A and 66B of the tilt guide portion 60 may be spaced apart in the first axial direction, and the first groove 55A and the second groove 55B of the housing 210 may be spaced apart in the first axial direction.

[0375] For example, the first projection 65 and the second projection 66 may, but are not limited to, have a curved, hemispherical, dome-shaped, or polyhedral shape. For instance, the shape of the first projection 65 as viewed from the front or above, and the shape of the second projection 66 as viewed from the rear or below, may be circular, elliptical, or polygonal.

[0376] The tilt guide section 60 may include an opening 60A that corresponds to, faces, or overlaps with the magnetic material 31 and / or magnetic material 33. For example, the opening 60A may correspond to, face, or overlap with the coupling section 49 of the housing 210. The opening 60A can reduce the weight (or mass) of the tilt guide section 60, thereby making the camera device 200 lighter.

[0377] For example, the opening 60A of the tilt guide portion 60 may be positioned to avoid spatial interference with the coupling portion 49 of the housing 210. Alternatively, the opening 60A of the tilt guide portion 60 may be formed to avoid spatial interference between the magnetic material 31 and the coupling portion 49 of the housing 210.

[0378] For example, the opening 60A of the tilt guide portion 60 may be a through hole or hollow. For example, the opening 60A may penetrate the tilt guide portion 60 along the first direction (Z-axis direction) or the optical axis direction. For example, at least a portion of the opening 60A of the tilt guide portion 60 may include a shape corresponding to the coupling portion 49 of the housing 210. For example, the opening 60A may include a circular, elliptical, polygonal, for example, quadrilateral shape.

[0379] When viewed from above, the opening 60A of the tilt guide portion 60 may be positioned between the protrusions 65A and 65B of the tilt guide portion 60. When viewed from below, the opening 60A of the tilt guide portion 60 may be positioned between the protrusions 66A and 66B of the tilt guide portion 60.

[0380] For example, the lateral length of the opening 60A of the tilt guide portion 60 may be greater than the lateral length of the joint portion 49 of the housing 210. In other embodiments, the lateral length of the opening 60A may be the same as the lateral length of the joint portion 49 of the housing 210. The vertical length of the opening 60A may be greater than the vertical length of the joint portion 49 of the housing 210. In other embodiments, the vertical length of the opening 60A may be the same as the vertical length of the joint portion 49 of the housing 210.

[0381] At least a portion of the coupling portion 49 of the housing 210 may be positioned within the opening 60A of the tilt guide portion 60. For example, in the optical axis direction, the coupling portion 49 of the housing 210 may overlap with the opening 60A of the tilt guide portion 60. Also, for example, in a direction perpendicular to the optical axis direction, the coupling portion 49 of the housing 210 may overlap with the tilt guide portion 60. This makes it possible to reduce the length or height of the camera device 200 in the optical axis direction.

[0382] For example, at least a portion of the opening 60A may be positioned between the two protrusions 65A and 65B of the first protrusion 65 of the tilt guide portion 60. Alternatively, at least a portion of the opening 60A may be positioned between the two protrusions 66A and 66B of the second protrusion 66 of the tilt guide portion 60.

[0383] For example, the tilt guide portion 60 may be an injection-molded product. For example, the tilt guide portion 60 may be made of plastic, resin, or ceramic material. In another embodiment, the tilt guide portion 60 may include a metallic material, such as SUS material. The tilt guide portion 60 may also be a non-magnetic material. In another embodiment, the tilt guide portion 60 may be a magnetic material.

[0384] The protrusions 65A and 65B of the first protrusion 65 and the protrusions 66A and 66B of the second protrusion 66 may be arranged in parallel in directions that intersect or are perpendicular to each other. The first protrusion 65 of the tilt guide portion 60 allows the OIS moving portion to rotate by a predetermined angle with respect to the first axis, or to rotate on an axis or tilt. The second protrusion 66 of the tilt guide portion 60 allows the OIS moving portion to rotate on an axis or tilt on a second axis.

[0385] In other embodiments, the tilt guide portion 60 may omit at least one of the first projection 65 and the second projection 66, and a rolling member or ball member may be provided in place of the omitted projection.

[0386] Referring to Figures 9c and 9d, the tilt guide portion 60-1 in other embodiments may omit the first projection 65 and include the first groove 75, and may omit the second projection 66 and include the second groove 76. Also, the support portion may include a first ball member instead of the first projection 65, and a second ball member instead of the second projection 66. For example, the first ball member may include two or more first ball members 65A1, 65B1, and the second ball member may include two or more ball members 66A1, 66B1.

[0387] The first groove 75 may be located on or formed on the first surface 6A of the tilt guide portion 60-1. The first surface 6A may be the surface facing or opposite the sensor base 270. The groove 75 may be recessed from the first surface 6A of the tilt guide portion 60. For example, the tilt guide portion 60-1 may include first grooves 75A, 75B for arranging at least portions of two first ball members 65A1, 65B1. For example, the first grooves 75A, 75B may be spaced apart in the first axial direction. For example, the first ball members 65A1, 65B1 may be spaced apart in the first axial direction.

[0388] In other embodiments, the first ball members 65A1 and 65B1 may be spaced apart in the second axial direction, and the first grooves 75A and 75B may be spaced apart in the second axial direction.

[0389] In another embodiment, the first ball members 65A1, 65B1 and the first grooves 75A, 75B may be arranged spaced apart in a first horizontal direction (or a second horizontal direction).

[0390] Furthermore, the second groove 76 of the tilt guide portion 60-1 may be located on or formed on the second surface 6B of the tilt guide portion 60-1. The second surface 6B is the surface facing or opposite the housing 210. Also, the second surface 6B may be the opposite surface of the first surface 6A of the tilt guide portion 60-1. The second groove 76 may be recessed from the second surface 6B of the tilt guide portion 60.

[0391] For example, the tilt guide portion 60-1 may include second grooves 76A, 76B for arranging at least a portion of two second ball members 66A1, 66B1. For example, the second grooves 76A, 76B may be spaced apart in the second axial direction. For example, the second ball members 66A1, 66B1 may be spaced apart in the second axial direction. In another embodiment, the second ball members 66A1, 66B1 may be spaced apart in the first axial direction, and the second grooves 76A, 76B may be spaced apart in the first axial direction. In yet another embodiment, the second ball members 66A1, 66B1 and the second grooves 76A, 76B may be spaced apart in the second horizontal direction (or first horizontal direction).

[0392] The description of the shape of the groove 29 in the sensor base 270 or the groove 55 in the housing 210 may be applied or by analogy to the shapes of the first groove 75 and the second groove 76 in the tilt guide portion 60-1.

[0393] A lubricant may be placed between the first projection 65 of the tilt guide portion 60 and the groove 29 of the sensor base 270, or between the second projection 66 of the tilt guide portion 60 and the groove 55 of the housing 210, in order to reduce friction and protect the tilt guide portion 60.

[0394] The first projection 65 of the tilt guide portion 60 can slide within the groove 29 of the sensor base 270, and the second projection 66 can slide within the groove 55 of the housing 210. This reduces the frictional force between the tilt guide portion 60 and the sensor base 270 and / or between the tilt guide portion 60 and the housing 210, thereby reducing the current consumption or power consumption required for OIS driving.

[0395] Referring to Figures 4d and 12, the rolling member 21 may not overlap with the tilt guide portion 60 in the optical axis direction. For example, as shown in Figure 4c, the rolling member 21 may not overlap with the tilt guide portion 60 in the direction perpendicular to the optical axis.

[0396] For example, the separation direction of the first rolling member 21A and the second rolling member 21B may intersect with the separation direction of the projections 65A and 65B of the tilt guide portion 60. For example, the separation direction of the first rolling member 21A and the second rolling member 21B may not be parallel or perpendicular to the separation direction of the projections 65A and 65B of the tilt guide portion 60.

[0397] For example, the separation direction of the first rolling member 21A and the second rolling member 21B may intersect with the separation direction of the projections 66A and 66B of the tilt guide portion 60. For example, the separation direction of the first rolling member 21A and the second rolling member 21B may not be parallel or perpendicular to the separation direction of the projections 66A and 66B of the tilt guide portion 60.

[0398] For example, when viewed from above, the distance between projections 65A and 65B of the tilt guide portion 60 may be smaller than the distance between the first rolling member 21A and the second rolling member 21B. In other embodiments, the distance between projections 65A and 65B of the tilt guide portion 60 may be the same as or greater than the distance between the first rolling member 21A and the second rolling member 21B.

[0399] For example, when viewed from above, the distance between projections 66A and 66B of the tilt guide portion 60 may be smaller than the distance between the first rolling member 21A and the second rolling member 21B. In another embodiment, the distance between projections 66A and 66B of the tilt guide portion 60 may be the same as or greater than the distance between the first rolling member 21A and the second rolling member 21B.

[0400] The support portion may include a magnetic body 33 located on the OIS moving portion (e.g., sensor base 270) and a magnetic body 31 located on the fixed portion (e.g., housing 210). The magnetic bodies 31 and 33 may be replaced with "magnets," "yokes," or "holding magnets." The support portion may include a support member 64.

[0401] For example, the magnetic material 31 may be placed in or coupled within the groove 49A of the coupling portion 49 of the housing 210. At least a portion of the magnetic material 31 may be placed within the opening 60A of the tilt guide portion 60. For example, the magnetic material 31 may face or overlap with the opening 60A of the tilt guide portion 60 in the optical axis direction. For example, the magnetic material 31 may not overlap with the tilt guide portion 60 in the optical axis direction. Also, for example, at least a portion of the magnetic material 31 may overlap with the tilt guide portion 60 in a direction perpendicular to the optical axis. For example, the magnetic material 31 may overlap with the tilt guide portion 60 in a direction parallel to the first axis or parallel to the second axis.

[0402] The magnetic material 31 may correspond to, face, or overlap with the magnetic material 33 in the optical axis direction. The magnetic material 31 may be positioned on the opposite side of the magnetic material 33.

[0403] The magnetic material 31 may be a two-pole magnet divided or arranged as a north pole and a south pole. For example, the magnetic material 31 may be a two-pole magnet in which the north pole and south pole are divided or arranged in the direction of the optical axis. In another embodiment, the magnetic material 31 may be a two-pole magnet divided or arranged as a north pole and a south pole in a direction perpendicular to the optical axis. In yet another embodiment, the magnetic material 31 may be a four-pole magnet containing two north poles and two south poles.

[0404] The support member 64 can be coupled to or assembled with the OIS moving part. For example, the support member 64 can be coupled to or assembled to the sensor base 270. For example, the support member 64 can be coupled to or assembled to the extension 217 of the sensor base 270. For example, the support member 64 can be coupled to the extension 217 of the base 270 by adhesive.

[0405] The support member 64 may be replaced with "magnetic support member," "sensor base rigid," "support part," "mover rigid," "holding rigid," "connecting part," or "plate." For example, the support member 64 may be formed from an injection molded product, plastic, or resin material. Alternatively, for example, the support member 64 may be formed from a metal material or a metal plate. Alternatively, the support member 64 may be formed from a heat dissipation member. The support member 64 may have a polyhedron (e.g., hexahedron) shape. The support member 64 may have a plate shape. For example, when viewed from above or along the optical axis, the support member 64 may have a polygonal shape, such as a quadrilateral shape. Also, when viewed from above or along the optical axis, the support member 64 may be rectangular, square, circular, or elliptical.

[0406] Figure 14a is a cross-sectional perspective view of the camera device 200, and Figure 14b is an enlarged view of the dotted line portion of Figure 14a.

[0407] Referring to Figures 14a and 14b, the support member 64 may be positioned at a distance from the tilt guide portion 60. The support member 64 may be located below the tilt guide portion 60 (or the body of the tilt guide portion 60). The image sensor 801 may be positioned closer to the magnetic material 31 than to the magnetic material 33.

[0408] At least a portion of the support member 64 may overlap with the magnetic material 31 in the optical axis direction. At least a portion of the support member 64 may overlap with the magnetic material 33 in the optical axis direction. The support member 64 may overlap with the opening 60A of the tilt guide portion 60 in the optical axis direction. The support member 64 may be located below the opening 60A of the tilt guide portion 60. The support member 64 may not overlap with the tilt guide portion 60 in the optical axis direction. The support member 64 may correspond to, face, or overlap with the extension 217 of the sensor base 270 in the optical axis direction. For example, the support member 64 may not overlap with the main body of the tilt guide portion 60 in a direction perpendicular to the optical axis direction. The lower surface of the support member 64 may be located higher than the lower surface of the lower part 42 of the housing 140. In other embodiments, the lower surface of the support member 64 may be located below the lower surface of the lower part 42 of the housing 140, or at the same height as the lower surface of the lower part 42 of the housing 140.

[0409] For example, the support member 64 may not overlap with the magnet 310 and / or coil 230 in the optical axis direction. The support member 64 may overlap with the image sensor 810 in the optical axis direction.

[0410] The moving module may include a portion (first portion) that passes through the opening 60A of the tilt guide portion 60 or is located inside the tilt guide portion 60. The magnetic material 33 may be coupled to the portion (or "first portion") of the moving module. For example, the magnetic material 33 may be coupled to the first portion of the moving module by an adhesive. For example, the sensor base 270 may include the first portion.

[0411] The support member 64 can be coupled to the first part of the mobile module. The magnetic material 33 can be placed on the support member 64. For example, the “first part” of the mobile module may be an extension 217 of the sensor base 270.

[0412] The fixed portion may include an opening 18 in which the first part of the movable module is positioned.

[0413] At least a portion of the extension 217 of the sensor base 270 may correspond to, face, or overlap with the aperture 60A of the tilt guide portion 60 in the optical axis direction. For example, the extension 217 may not overlap with the tilt guide portion 60 in the optical axis direction. In other embodiments, a portion of the extension 217 may overlap with the tilt guide portion 60 in the optical axis direction.

[0414] At least a portion of the extension 217 may be positioned within the opening 60A of the tilt guide portion 60. For example, at least a portion of the extension 217 may pass through the opening 60A of the tilt guide portion 60. For example, at least a portion of the extension 217 may pass through or penetrate the opening 60A of the tilt guide portion 60 and be connected to the support member 64. That is, as shown in Figures 4b and 14b, the end of the extension 217 may be located below the lower surface of the tilt guide portion 60.

[0415] In other embodiments, the end of the extension 217 may be located within the opening 60A of the tilt guide portion 60. For example, the end of the extension 217 may be located between the upper and lower surfaces of the tilt guide portion 60.

[0416] In the embodiment shown in Figure 7d, the extension 217 is part of the sensor base 270 and may be formed integrally with the sensor base 270. In other embodiments of the camera device, a coupling member separate from the sensor base 270 may be provided instead of the extension 217. In this case, the separate coupling member may be coupled to the sensor base 270. For example, the coupling member may be coupled to the sensor base 270 by adhesive. The coupling member may include a first coupling structure (e.g., a projection or groove), and the sensor base 270 may include a second coupling structure (e.g., a groove or projection) for coupling to the first coupling structure. For example, one end of the coupling member may be coupled to the lower part (or bottom surface) of the sensor base 270, and the other end of the coupling member may be coupled to the support member 64. At least a portion of the coupling member may be located within the opening 60A of the tilt guide portion 60. The coupling member may pass through the opening 60A of the tilt guide portion 60 and be coupled to the support member 64. In this case, the sensor base 270 may not include a portion located within the opening 60A of the tilt guide portion 60.

[0417] In this embodiment, the support member 64 is coupled to the extension 217 of the sensor base 270, which passes through the opening 60A of the tilt guide portion 60, and does not overlap with the main body of the tilt guide portion 60 in the optical axis direction. That is, the size of the support member 64 can be reduced and its shape can be simplified.

[0418] In the comparative example camera device, the support member may overlap with at least a portion of the tilt guide portion in the optical axis direction, and the support member may include an extension that extends to at least one corner portion of the housing.

[0419] For the movable part (e.g., the sensor base 270) to tilt with respect to the first or second axis, space is required between the sensor base 270 and the housing 210. In the comparative example, the extension of the support member can increase the space required for the sensor base 270 to tilt with respect to the first or second axis.

[0420] On the other hand, in the embodiment, the support member 64 may have a simple structure in which it does not overlap with the tilt guide portion 60 in the optical axis direction. In the embodiment, the size of the support member 64 can be designed to be smaller. Also, in the embodiment, the end of the support member 64 may be positioned closer to the optical axis or the center or central region of the tilt module than to the corner portion of the housing 210. As a result, compared to the comparative example, the space required for tilting the sensor base, which is the OIS moving part for image stabilization, can be reduced in the embodiment, and the size of the camera device can be reduced.

[0421] The magnetic material 33 may be positioned below the magnetic material 31. The magnetic material 31 may be positioned higher than the magnetic material 33.

[0422] The magnetic material 33 may be placed on or coupled to the support member 64. Referring to Figure 7a, the support member 64 may include a mounting portion 93A (or housing portion). The mounting portion 93A may be a groove. For example, the mounting portion 93A may be a groove recessed from the upper surface of the support member 64. For example, the magnetic material 33 may be coupled to the mounting portion 93A of the support member 64. For example, the magnetic material 33 can be bonded, attached to, or fixed to the mounting portion 93A of the support member 64 by an adhesive.

[0423] The magnetic material 33 may overlap with the aperture 60A of the tilt guide portion 60 in the optical axis direction. The magnetic material 33 may not overlap with the tilt guide portion 60 in the optical axis direction.

[0424] Referring to Figures 14a and 14b, the magnetic material 33 may not overlap with the tilt guide portion 60 in a direction perpendicular to the optical axis. In other embodiments, the magnetic material 33 may overlap with the tilt guide portion 60 in a direction perpendicular to the optical axis.

[0425] When viewed from above, the area of ​​the opening 60A of the tilt guide portion 60 may be larger than the area of ​​the upper (or lower) surface of the magnetic material 31. Also, when viewed from above, the area of ​​the opening 60A of the tilt guide portion 60 may be larger than the area of ​​the upper (or lower) surface of the magnetic material 33.

[0426] A repulsive force may act between magnetic material 33 and magnetic material 31 in the optical axis direction (or first direction). Magnetic material 33 and magnetic material 31 may be arranged so that a repulsive force acts between them. Magnetic material 33 may be composed of a magnetic material. For example, magnetic material 33 may include a magnetic metallic material. Alternatively, for example, magnetic material 33 may be composed of a magnetic metallic material. Also, for example, magnetic material 33 may be a magnet. Magnetic materials 31 and 32 may be replaced with "yoke". Magnetic materials 33 and 31 may each be replaced with "repulsive magnet".

[0427] For example, magnetic materials 33 and 31 may be arranged such that their faces, which face or are opposite each other in the optical axis direction, have the same polarity. For example, the north pole (or south pole) of magnetic material 33 and the north pole (or south pole) of magnetic material 31 may face or be opposite each other in the optical axis direction.

[0428] For example, the first surface of magnetic material 33 may face the first surface of magnetic material 31, and the first surface of magnetic material 33 and the first surface of magnetic material 31 may have the same polarity. For example, the second surface of magnetic material 33 may be the opposite surface of the first surface of magnetic material 33, and the second surface of magnetic material 31 may be the opposite surface of the first surface of magnetic material 31, and the second surface of magnetic material 33 and the second surface of magnetic material 31 may have the same polarity.

[0429] Referring to Figures 14a and 14b, the coupling portion 49 of the housing 210 may be positioned between the sensor base 270 and the support member 64. The coupling portion 49 and the magnetic material 31 may be positioned between the sensor base 270 and the magnetic material 33 positioned on the support member 64.

[0430] The image sensor 810 or filter 610 may be positioned closer to the magnetic material 31 than to the magnetic material 33. That is, of the magnetic material 31 and the magnetic material 33, the magnetic material 31 may be positioned closer to the image sensor 810. For example, the lower surface of the lower part 42 of the housing 210 may be positioned closer to the magnetic material 33 than to the magnetic material 31. For example, the support member 64 and the magnetic material 33 may be positioned below the tilt guide portion 60.

[0431] The tilt guide portion 60 can be brought into close contact with the OIS moving portion and the fixed portion by the repulsive force acting between the magnetic material 33 and the magnetic material 31. The tilt guide portion 60 can be pressed against the moving portion by the repulsive force of the magnetic material 33 and the magnetic material 31.

[0432] The repulsive force acting between the magnetic material 33 and the magnetic material 31 allows the lower surface of the sensor base 270 to press against the tilt guide portion 60. The repulsive force acting between the magnetic material 33 and the magnetic material 31 also allows the lower part 42 of the housing 210 to press against the tilt guide portion 60. As a result, the first projection 65 and the second projection 66 of the tilt guide portion 60 can be in close contact with the sensor base 270 and / or the housing 210. The repulsive force between the magnetic material 33 and the magnetic material 31 allows the tilt guide portion 60 to stably support the OIS moving portion 100 relative to the fixed portion, enabling stable OIS operation.

[0433] Furthermore, since at least a portion of the magnetic material 31 is positioned within the opening 60A of the tilt guide portion 60, the separation distance between the magnetic material 31 and the magnetic material 33 can be reduced, thereby increasing the repulsive force between the magnetic material 31 and the magnetic material 33, allowing the OIS moving portion to be stably supported by the fixed portion and enabling stable OIS operation.

[0434] Furthermore, since the magnetic body 31 is positioned in a coupling portion 49 corresponding to or facing the central region of the lower part 42 of the housing 210, and the magnetic body 33 is positioned in a region of the support member 64 corresponding to or facing the central region of the lower surface of the sensor base 270, the repulsive force between the magnetic body 31 and the magnetic body 33 can be concentrated in the central region of the sensor base 270 and the central region of the housing 210, allowing the OIS moving part to be supported efficiently and stably.

[0435] In other embodiments, the coupling portion 49 of the housing 210 may be omitted, and the magnetic body 31 may be placed on the upper surface of the lower portion 42 of the housing 210. Also, the mounting portion 69 of the housing 210 may be omitted, and a mounting portion corresponding to or identical to the mounting portion 69 of the housing 210 may be formed on the lower surface of the sensor base 270, and the tilt guide portion 60 may be placed within the mounting portion of the sensor base 270.

[0436] In other embodiments, the tilt guide portion 60 may be omitted, and the support portion may include a rolling member, such as a ball member, positioned between the sensor base 270 and the housing 210. In this case, the rolling member may include two first ball members positioned parallel to the first axis and two second ball members positioned parallel to the second axis. The OIS moving portion may tilt or rotate by a predetermined angle around the first ball members, and may tilt or rotate by a predetermined angle around the second ball members. Image stabilization may be performed based on the result.

[0437] Referring to Figures 12 and 16a, when viewed from above, the first magnet unit 310A may overlap with the projections 65A and 65B of the tilt guide portion 60 in the direction in which the projections 65A and 65B face each other or in the first axial direction. Also, the second magnet unit 310B may overlap with the projections 65A and 65B of the tilt guide portion 60 in the direction in which the projections 66A and 66B face each other or in the second axial direction.

[0438] Referring to Figures 4e and 4f, the tilt guide portion 60 may overlap with the magnet 310 in a direction perpendicular to the optical axis. For example, the first magnet unit 310A may overlap with the tilt guide portion 60 in the first axial direction, and the second magnet unit 310B may overlap with the tilt guide portion 60 in the second axial direction.

[0439] For example, the magnet 310 and yoke 380 may be positioned below the image sensor 810. For example, the magnet 310 may be positioned below the filter 610. Also, the magnet 310 may be positioned below the magnetic material 33. For example, the magnet 310 may be located below the holder 140. For example, it may be positioned below the sensor base 270. For example, the upper surface of the magnet 310 may be located below the lower surface of the sensor base 270. The upper surface of the magnet 310 may be located below the lower surface of the holder 140. The upper surface of the magnet 310 may be located below the lower surface of the magnetic material 33. For example, the magnet 310 may be positioned below the rolling member 21.

[0440] Referring to Figure 4f, the upper surface of the magnet 310, for example, the upper surface of magnet units 310A and 310B, may be located below the upper surface of the magnetic body 31. In other embodiments, the upper surface of the magnet 310 may be located higher than the upper surface of the magnetic body 31, or it may be at the same height as the upper surface of the magnetic body 31.

[0441] Furthermore, the upper surface of the magnet 310, for example, the upper surface of magnet units 310A and 310B, may be located below the lower surface of the magnetic body 31. In other embodiments, the upper surface of the magnet 310 may be located higher than the lower surface of the magnetic body 31, or it may be at the same height as the lower surface of the magnetic body 31. For example, the support member 64 and the magnetic body 33 may be located below the coupling portion 49 of the housing 210.

[0442] Referring to Figure 12, for example, the first magnet unit 310A and the second magnet unit 310B may be identical in shape and size.

[0443] The first length L1 of the first magnet unit 310A in the second axial direction may be smaller than the second length L2 of the first magnet unit 310A in the first axial direction. Similarly, the first length of the second magnet unit 310B in the first axial direction may be smaller than the second length of the second magnet unit 310B in the second axial direction. The length of the first magnet unit 310A in the optical axis direction may be smaller than the second length L2 of the first magnet unit 310A. Similarly, the length of the second magnet unit 310B in the optical axis direction may be smaller than the second length of the second magnet unit 310B. In other embodiments, the length of the first magnet unit 310A (or the second magnet unit 310B) in the optical axis direction may be the same as or greater than the second length L2 of the first magnet unit 310A (or the second magnet unit 310B).

[0444] For example, the first length L1 of the first magnet unit 310A (or the second magnet unit 310B) may be smaller than the length of the tilt guide portion 60 in the second direction (X-axis direction) or the third direction (Y-axis direction). For example, the first length L1 of the first magnet unit 310A (or the second magnet unit 310B) may be larger than the length M1 between the outer and inner surfaces of the tilt guide portion 60. For example, M1 may be the shortest distance between the outer surface of the tilt guide portion 60 and the opening 60A of the tilt guide portion 60. In other embodiments, L1 may be the same as or smaller than M1.

[0445] For example, the first length L1 of the first magnet unit 310A (or the second magnet unit 310B) may be smaller than the length of the opening 60A of the tilt guide portion 60 in the first or second axial direction. Also, the first length L1 of the first magnet unit 310A (or the second magnet unit 310B) may be smaller than the length of the opening 60A of the tilt guide portion 60 in the second or third direction. In other embodiments, L1 may be the same as or larger than the length of the opening 60A in the first or second axial direction. Alternatively, L1 may be the same as or larger than the length of the opening 60A of the tilt guide portion 60 in the second or third direction.

[0446] Referring to Figures 9a, 9b, and 12, the minimum separation distance L3 between the first projections 65A and 65B may be greater than the first length L1. The minimum separation distance L4 between the second projections 66A and 66B may also be greater than the first length L1. For example, L3 and L4 may be the same. In other embodiments, L3 and L4 may be different from each other. The description of L3 and L4 may also apply or be applied by analogy to the first ball members 65A1 and 65B1 and the second ball members 66A1 and 66B1 shown in Figures 9c and 9d.

[0447] For example, the upper surface of the magnet 310 may be located below the upper surface of the coupling portion 49 of the housing 210. This is to ensure sufficient space to avoid spatial interference between the magnet 310 and the lower surface of the sensor base 270. In other embodiments, the upper surface of the magnet 310 may be located higher than the upper surface of the coupling portion 49 of the housing 210. In yet another embodiment, the upper surface of the magnet 310 and the upper surface of the coupling portion 49 of the housing 210 may be at the same height. For example, the upper surface of the magnet 310 may be located below the highest point of the first projection 65 of the tilt guide portion 60.

[0448] When viewed from above or along the optical axis, the protrusions 65A, 65B, magnetic material 31, and first magnet unit 310A may overlap in the first axis direction. Also, when viewed from above or along the optical axis, the protrusions 66A, 66B, magnetic material 31, and second magnet unit 310B may overlap in the second axis direction.

[0449] When viewed from above or along the optical axis, the magnet 310 may not overlap with the magnetic material 31 in the second direction (X-axis direction) or the third direction (Y-axis direction).

[0450] In other embodiments, when viewed from above or along the optical axis, the magnet 310 may overlap with the magnetic material 31 in a second direction (X-axis direction) or a third direction (Y-axis direction).

[0451] Figure 15 is a perspective view of the camera device including the shield member 390.

[0452]

[0453] Referring to Figure 15, the camera device may include a shielding member 390 that closes the opening 18 of the housing 210. The shielding member 390 may be bonded or attached to the lower surface of the lower part of the housing 210. The shielding member 390 may be bonded to the housing 210 by adhesive. For example, the shielding member 390 may be in the form of adhesive tape. The shielding member 390 may be replaced by the terms “cover”, “sealing member”, or “shielding tape”.

[0454] In Figure 15, the support member 64 may include a long side and a short side, and the long side of the support member 64 may be positioned parallel to a second direction (X-axis direction) or a third direction. In other embodiments, the long side of the support member 64 may be positioned to intersect with the second and third directions. In other embodiments, the long side of the support member 64 may be positioned parallel to a first axis or a second axis.

[0455] Figure 16a shows the electromagnetic forces F1 and F2 due to the interaction between the magnet units 310A and 310B and the coil units 230A and 230B, and Figure 16b shows the movement of the OIS moving part 100 due to the electromagnetic forces in Figure 16a. Figure 16a shows the electromagnetic forces when the first magnet unit 310A and the second magnet unit 310B are two-pole magnets having a north pole and a south pole.

[0456] Referring to Figures 16a and 16b, the movement of the OIS moving part by the OIS drive unit will be explained. The OIS drive unit may include a coil 230 and a magnet 310. The OIS drive unit may also include a position sensor 240. The AF drive unit may be represented by either the "first drive unit" or the "second drive unit," and the OIS drive unit may be represented by the other of the "first drive unit" and the "second drive unit."

[0457] For example, the first surface (e.g., top surface) of the first magnet unit 310A facing or opposite the first coil unit 230A in the optical axis direction and the first surface (e.g., top surface) of the second magnet unit 310B facing or opposite the second coil unit 230B in the optical axis direction may have opposite polarities. By making the first surface (e.g., top surface) of the first magnet unit 310A and the first surface (e.g., top surface) of the second magnet unit 310B have opposite polarities, the influence of the magnetic field of the first magnet unit 310A on the second coil unit 230B and the influence of the magnetic field of the second magnet unit on the first coil unit 230A cancel each other out, and a magnetic field balance can be achieved. As a result, the influence of unwanted magnetic fields caused by the two adjacent magnet units 310A and 310B on the coil units 230A and 230B can be suppressed or reduced, and the camera device 200 can improve the performance and reliability of OIS drive.

[0458] Furthermore, by arranging the first surface (e.g., top surface) of the first magnet unit 310A and the first surface (e.g., top surface) of the second magnet unit 310B to have opposite polarities, the magnetic field influence of the first magnet unit 310A on the second sensor 240B and the magnetic field influence of the second magnet unit on the first sensor 240A cancel each other out, achieving a magnetic field balance. This suppresses or reduces the influence of unwanted magnetic fields from adjacent magnet units 310A and 310B on sensors 240A and 240B, improving the reliability of the output of sensors 240A and 240B, and thereby improving the performance and reliability of OIS drive.

[0459] Furthermore, for example, the second surface (e.g., bottom surface) of the first magnet unit 310A and the second surface (e.g., bottom surface) of the second magnet unit 310B may have opposite polarities. The second surface (e.g., bottom surface) of the first magnet unit 310A may be the opposite surface of the first surface (e.g., top surface) of the first magnet unit 310A and may have polarity opposite to that of the first surface (e.g., top surface) of the first magnet unit 310A. The second surface (e.g., bottom surface) of the second magnet unit 310B may be the opposite surface of the first surface (e.g., top surface) of the second magnet unit 310B and may have polarity opposite to that of the first surface (e.g., top surface) of the second magnet unit 310B. For example, the first surface of the first magnet unit 310A may be a north pole (or south pole), and the first surface of the second magnet unit 310B may be a south pole (or north pole).

[0460] 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 direction of the optical axis, for example, upward or downward. The first electromagnetic force F1 allows the OIS moving part 100 to tilt about the second axis (or second projection 66). For example, the first electromagnetic force F1 allows the OIS moving part 100 to tilt about the second axis. Here, second-axis tilting may mean that the OIS moving part is tilted with respect to the second axis, or that the OIS moving part rotates by a predetermined angle with respect to the second axis as the axis of rotation.

[0461] For example, the tilt guide portion 60 can be tilted around the second axis (or the protrusions 66A and 66B of the second protrusion 66) by the first electromagnetic force F1. For example, the tilt guide portion 60 can be tilted around the second axis by the first electromagnetic force F1. For example, in an embodiment where the arrangement of protrusions 66A and 66B is in the first axis direction, the tilt guide portion 60 may also be tilted around the first axis.

[0462] Referring to Figure 4b, in order for the OIS moving part to be tilted with respect to the second axis (or the second projection 66 of the tilt guide part 60), a gap or space must exist between the tilt guide part 60 and the OIS moving part (such as the sensor base 270) due to the first projection 65 of the tilt guide part 60. For example, a gap or space may exist between the upper surface 6A of the tilt guide part 60 and the OIS moving part (e.g., the sensor base 270) that allows the tilt guide part 60 to move. For example, the upper surface 6A of the tilt guide part 60 may be separated from the OIS moving part (e.g., the sensor base 270) or the lower surface of the sensor base 270.

[0463] The interaction between the second magnet unit 310B and the second coil unit 230B may generate a second electromagnetic force F2. For example, the second electromagnetic force F2 may act in an upward or downward direction.

[0464] The OIS moving part can be tilted about the first axis (or first projection 65) by the second electromagnetic force F2. For example, the OIS moving part can be tilted about the first axis by the second electromagnetic force F2. Here, first axis tilt may mean that the OIS moving part is tilted with respect to the first axis, or that the OIS moving part rotates by a predetermined angle with respect to the first axis as the axis of rotation.

[0465] For example, the tilt guide portion 60 can come into contact with a fixed portion (e.g., housing 210) by tilting on the first or second axis, in which case the fixed portion acts as a stopper to suppress the tilt of the OIS moving portion.

[0466] Figure 16c shows the arrangement of magnet units 310A and 310B according to a modification of Figure 16a. Referring to Figure 16c, the first surface (e.g., top surface) of the first magnet unit 310A facing or opposite the first coil unit 230A in the optical axis direction, and the first surface (e.g., top surface) of the second magnet unit 310B facing or opposite the second coil unit 230B in the optical axis direction, may have the same polarity. For example, the first surface of the first magnet unit 310A and the first surface of the second magnet unit 310B may be north poles (or south poles), and the second surface of the first magnet unit 310A and the second surface of the second magnet unit 310B may be south poles (or north poles).

[0467] Figure 16d shows the electromagnetic forces F11 and F12 resulting from the interaction between the magnet units 310A1 and 310B1 and the coil units 230A and 230B according to another embodiment.

[0468] Referring to Figure 16d, the first magnet unit 310A1 may be a magnet divided or arranged in the first axial direction into one north pole and one south pole. The second magnet unit 310B1 may be a magnet divided or arranged in the second axial direction into one north pole and one south pole. For example, the first surface of the first magnet unit 310A1 may include a north pole and a south pole, and the first surface of the second magnet unit 310B1 may also include a north pole and a south pole.

[0469] The first electromagnetic force F11 resulting from the interaction between the first magnet unit 310A1 and the first coil unit 230A may act in a direction different from the optical axis (for example, in the first axial direction). The second electromagnetic force F12 resulting from the interaction between the second magnet unit 310B1 and the second coil unit 230B may act in a direction different from the optical axis (for example, in the second axial direction).

[0470] For example, the first electromagnetic force F11 resulting from the interaction between the first magnet unit 310A1 and the first coil unit 230A may act in a direction perpendicular to the optical axis. Similarly, the second electromagnetic force F12 resulting from the interaction between the second magnet unit 310B1 and the second coil unit 230B may act in a direction perpendicular to the optical axis. For example, F11 and F12 may act in directions that intersect each other (e.g., perpendicular directions).

[0471] In Figure 16d, the first pole of the first magnet unit 310A1 may be positioned closer to the tilt guide portion 60 than the second pole of the first magnet unit 310A1. Also, the second pole of the second magnet unit 310B1 may be positioned closer to the tilt guide portion 60 than the first pole of the second magnet unit 310B1. Alternatively, the first pole of the first magnet unit 310A1 may be located on the inside, and the second pole of the first magnet unit 310A1 may be located on the outside. On the other hand, the first pole of the second magnet unit 310B1 may be located on the outside, and the second pole of the second magnet unit 310B1 may be located on the inside. For example, the first pole may be the north pole (or south pole), and the second pole may be the south pole (or north pole). In other embodiments, the first magnet unit 310A1 and the second magnet unit 310B1 may be positioned such that their opposite polarities are closer to the tilt guide portion 60. The description of the magnetic field balance in the embodiment of Figure 16a may also be applied or by analogy to the embodiment of Figure 16d.

[0472] In other embodiments, the first magnet unit 310A1 and the second magnet unit 310B1 may be arranged such that the same polarity (N pole or S pole) is closer to the tilt guide portion 60.

[0473] The OIS moving part can be tilted about the second axis (or second projection 66) by the first electromagnetic force F11. For example, the OIS moving part can be tilted about the second axis by the first electromagnetic force F11. The OIS moving part can be tilted about the first axis (or first projection 65) by the second electromagnetic force F12. For example, the OIS moving part can be tilted about the first axis by the second electromagnetic force F12.

[0474] In Figures 16a, 16c, and 16d, the yoke 380 can play a role in increasing the electromagnetic forces F1, F2, F11, F12 (or driving force).

[0475] In Figures 16a to 16d, the OIS moving part can be tilted with respect to a diagonal first or second axis by means of the magnet units 310A and 310B, the coil units 230A and 230B, and the tilt guide section 60. In other embodiments, the arrangement of the magnet units 310A and 310B and the coil units 230A and 230B, and the arrangement of the axes by the projections 65 and 66 of the tilt guide section can be modified to enable X-axis tilt or Y-axis tilt.

[0476] In a camera device (hereinafter referred to as "Comparative Example 1") where the image sensor is fixed and the lens is moved perpendicular to the optical axis for image stabilization or shake correction, image distortion may occur. Also, in a camera device ("Comparative Example 2") where the lens is fixed and the image sensor is moved or tilted for image stabilization or shake correction, image distortion may occur at the edges or corners of the image sensor. Thus, in Comparative Examples 1 and 2, the image sensor and lens are separated, and only one of the image sensor or lens moves or tilts, so image distortion may occur during image stabilization, making wide-angle image stabilization difficult.

[0477] In one embodiment, for image stabilization, the OIS drive unit can tilt the OIS moving unit 100 with respect to a first or second axis, or rotate it within a predetermined angular range. In one embodiment, since the OIS moving unit 100 includes a lens module 400 and an image sensor 810, when the OIS is driven, the tilt direction (or rotation direction) and tilt angle (or rotation angle) of the lens module 400 (e.g., lens or lens module) (or bobbin 110) may be the same as or nearly the same as the tilt direction (or rotation direction) and tilt angle (or rotation angle) of the image sensor 810.

[0478] In this embodiment, when OIS is driven, both the lens module 400 (or bobbin 110) and the image sensor 810 tilt or rotate, resulting in no image distortion, 100% image resolution, and wide-angle image stabilization or shake correction.

[0479] Furthermore, in this embodiment, since the OIS moving unit, which includes the lens module 400 (or bobbin 110) and the image sensor 810, tilts or rotates, image degradation does not occur in the central part of the image sensor or in the outer periphery of the image sensor (for example, the corners or corner regions of the image sensor) even if the camera device is shaken. As a result, this embodiment may enable wideband image stabilization. In addition, since distortion-free image correction is possible in this embodiment, the load on the image processing is reduced compared to Comparative Examples 1 and 2, and current consumption can be reduced.

[0480] Furthermore, in this embodiment, since the tilt guide portion 60 is used for tilting the OIS moving portion, the OIS moving portion can be tilted stably, precisely, and accurately compared to examples that simply utilize a ball member or a shaft member, thereby improving the reliability of the OIS drive.

[0481] Furthermore, 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 when driving the OIS.

[0482] Furthermore, in this embodiment, the tilt guide portion 60 is positioned within the mounting portion 69 of the housing 210, and the coupling portion 49 of the housing 210 overlaps with the opening 60A of the tilt guide portion 60, thereby reducing the height or length of the camera device 200 in the optical axis direction.

[0483] Furthermore, in this embodiment, since at least a portion of the magnetic material 31 is positioned within the opening 60A of the tilt guide portion 60, the distance between the magnetic material 31 and the magnetic material 33 can be reduced, thereby increasing the repulsive or holding force for supporting the OIS moving portion, and enabling stable OIS driving.

[0484] Furthermore, in this embodiment, the first magnet unit 310A and the second magnet unit 310B, which are drive magnets for image stabilization, are located in the lower part 42 of the housing 210 rather than in the sides 71A to 71D of the housing 210. This reduces the thickness (or length perpendicular to the optical axis) of the sides 71A to 71D of the housing 210, thereby enabling the design of the camera device to accommodate a large-aperture lens.

[0485] Figure 17 is a perspective view of the camera device 200, including the lens module 400.

[0486] Referring to Figure 17, the lens module 400 is coupled to the bobbin 110 and can 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. In this embodiment, during image stabilization or shake correction, the lens module 400 and the image sensor 810 can simultaneously tilt along the first axis or the second axis by the same direction and angle.

[0487] Figure 18a shows the first position of the OIS moving unit 100, and Figure 18b shows the second position of the OIS moving unit 100.

[0488] Referring to Figures 16a, 18a, and 18b, the force F1 resulting from the interaction between the first magnet unit 310A and the first coil unit 230A allows the OIS moving unit 100 to tilt by a predetermined angle on the second axis relative to the second axis. That is, when the OIS moving unit 100 moves from the first position to the second position, both the image sensor 810 and the lens module 400 can simultaneously tilt by the predetermined angle on the first axis. Also, when the OIS moving unit 100 moves from the first position to the second position, the tilt guide unit 60 can tilt together with the image sensor 810 and the lens module 400 by the predetermined angle on the first axis.

[0489] Figure 18c shows the third position of the OIS moving part 100.

[0490] Referring to Figure 18c, the force F2 resulting from the interaction between the second magnet unit 310B and the second coil unit 230B allows the OIS moving unit 100 to tilt by a predetermined angle θ2 with respect to the first axis. For example, when the OIS moving unit 100 moves from the first position to the third position, both the image sensor 810 and the lens module 400 can tilt simultaneously by the predetermined angle θ2.

[0491] Due to force F1 or force F2, the image sensor 810 and lens module 400 are simultaneously tilted with respect to the first or second axis. As a result, this embodiment achieves no image distortion, 100% image resolution, and wide-angle image stabilization or shake correction.

[0492] For example, when viewed from above or along the optical axis, the first axis may be the first diagonal direction of the OIS moving unit 100, and the second axis may be the second diagonal direction of the OIS moving unit 100. For example, the first diagonal direction of the OIS moving unit may be the first diagonal direction of any one of the holder 140, the sensor base 270, or the first substrate 801 of the circuit board 900. Also, the second diagonal direction of the OIS moving unit may be the second diagonal direction of any one of the holder 140, the sensor base 270, or the first substrate 801 of the circuit board 900.

[0493] In other embodiments, when viewed from above or along the optical axis, the first axis may be the first diagonal direction of the fixed portion, and the second axis may be the second diagonal direction of the fixed portion. For example, the first diagonal direction of the fixed portion may be the first diagonal direction of the housing 210 or the cover member 300. Also, the second diagonal direction of the fixed portion may be the second diagonal direction of the housing 210 or the cover member 300.

[0494] For example, the first diagonal direction of the OIS moving part 100 (or fixed part) may intersect with a second direction (e.g., the X-axis direction) or a third direction, and the second diagonal direction of the OIS moving part 100 (or fixed part) may intersect with a second direction (e.g., the X-axis direction) or a third direction. The first diagonal direction and the second diagonal direction of the OIS moving part 100 may intersect with each other. For example, the first diagonal direction and the second diagonal direction of the OIS moving part 100 may be perpendicular to each other.

[0495] In another embodiment, the first axis may be the first horizontal direction of the OIS moving part 100 (or fixed part), and the second axis may be the second horizontal direction of the OIS moving part 100 (or fixed part).

[0496] Figure 19 shows another modified embodiment 200-1 of Figure 14a.

[0497] Referring to Figure 19, the camera device 200-1 may omit the magnetic material 33 in the camera device 200, and the support member 64-1 may play the role of the omitted magnetic material 33. In Figure 19, the support member 64-1 may be replaced with "magnetic material".

[0498] The magnetic material 64-1 can be coupled to the sensor base 270. For example, the magnetic material 64-1 can be coupled to the extension 217 of the sensor base 270. For example, the magnetic material 64-1 can be coupled to the extension 217 of the sensor base 270 by adhesive. Alternatively, for example, the magnetic material 64-1 can be coupled to the extension 217 of the sensor base 270 by pin-hole coupling or male-to-female coupling. For example, either the extension 217 or the magnetic material 64-1 may be a pin (or hole), and the other of the extension 217 or the magnetic material 64-1 may be a hole (or pin).

[0499] The descriptions of the magnetic material 33 and the support member 64 may be applied or by analogy to the magnetic material 64-1 in Figure 19. A repulsive force may act between the magnetic material 31 and the magnetic material 64-1, and the magnetic material 31 and the magnetic material 64-1 may play a role in supporting the OIS moving part.

[0500] In the embodiment shown in Figure 19, the magnetic material 33 is omitted, and the support member 64-1 takes over its role. Therefore, compared to the embodiment in Figure 14a, it is possible to achieve performance equivalent to that of the embodiment in Figure 14a while reducing the number of parts and thus reducing the weight of the camera device.

[0502] Referring to Figures 20 to 32, the camera device 1200 may include a fixed part, an AF moving part, an OIS moving part 1100, and a support part. The OIS moving part 1100 may be replaced with "moving part," "oscillating part," or "movable part."

[0503] A fixed part can be a fixed element. That is, a fixed part may not move in the optical axis direction. Also, a fixed part may not move or tilt in a direction perpendicular to the optical axis. Furthermore, a configuration coupled to a fixed part may also be considered a fixed part.

[0504] 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 that is arranged on or coupled to the housing 1210 or the cover member 1300. For example, the fixing portion may include at least one of a magnet 1310 and a movement-restricting portion 1080 arranged on the housing 1210.

[0505] The AF moving part is movable in the optical axis direction relative to the fixed part. For example, the AF moving part may include a bobbin 1110. In other embodiments, the AF moving part may further include a configuration coupled to the bobbin 1110 (e.g., a magnet 1130). In other embodiments, the AF moving part may further include a lens module 1400 (see Figure 36) coupled to the bobbin 1110.

[0506] The OIS moving unit 1100 (see Figure 21a) is movable or tiltable to the left or right with respect to a first axis (e.g., pitch) that intersects the optical axis relative to the fixed unit. The OIS moving unit is also movable or tiltable to the left or right with respect to a second axis (e.g., yaw) that intersects the optical axis relative to the fixed unit. For example, the first axis may be perpendicular to the optical axis direction, and the second axis may be perpendicular to both the optical axis direction and the first axis. For example, the first axis may intersect the X-axis or the Y-axis. For example, the second axis may intersect the X-axis or the Y-axis. For example, the first and second axes may be perpendicular to each other. In other embodiments, the first axis may be either the X-axis or the Y-axis, and the second axis may be the other of the X-axis and the Y-axis.

[0507] For example, the OIS moving unit 1100 may include an AF moving unit. The OIS moving unit may also include an image sensor 1810. The OIS moving unit 1100 may include a circuit board 1800 on which the image sensor 1810 is arranged. The OIS moving unit 1100 may also include a sensor base 1270 on which at least a portion of the circuit board 1800 is arranged. The OIS moving unit may also include a holder 1140 that is coupled to the sensor base 1270.

[0508] The OIS moving unit 1100 may be represented as a first moving unit (or first movable unit), and the AF moving unit may be replaced by a second moving unit (or second movable unit). For example, the first moving unit may include a sensor base 1270 and a circuit board 1800.

[0509] Furthermore, for example, the OIS moving unit 1100 may include a configuration in which it is disposed of or coupled to at least one of the holder 1140, the sensor base 1270, and the circuit board 1800. For example, the OIS moving unit 1100 may include a filter 1610 disposed on the holder 1140. For example, the OIS moving unit 1100 may include a support member 1064 coupled to the sensor base 1270.

[0510] For example, the OIS moving part 1100 may include an elastic member 1033 that connects to a support member 1064. The support member 1064 may include a connecting part 1093A that connects to a part (or one end) of the elastic member 1033. The connecting part 1093A of the support member 1064 may include a groove that connects to a part (or one end) of the elastic member 1033.

[0511] The fixing portion may include a connecting portion 1049 that connects to another part (or the other end) of the elastic member 1033. The connecting portion 1049 of the fixing portion may include a groove that connects to another part (or the other end) of the elastic member 1033.

[0512] For example, the OIS moving unit 1100 may include at least one of the following components arranged on the circuit board 1800: an image sensor 1810, sensors 1170 and 1240, coils 120 and 230, a circuit element 1815, and a control unit 1830.

[0513] Furthermore, the OIS moving unit 1100 may include a moving module (or tilt module) and a support member 1064. For example, the moving module (or tilt module) may include at least one of the other configurations of the aforementioned OIS moving unit 1100, excluding the support member 1064.

[0514] For example, the moving module (or tilt module) may include a lens module 1400 and an image sensor 1810. The moving module (or tilt module) may also include a sensor base 1270. Furthermore, for example, the moving module (or tilt module) may further include at least one of a holder 1140 and a circuit board 1800. For example, the moving module (or tilt module) is tiltable with respect to a first or second axis. For example, the moving module may be expressed as a "mover".

[0515] The support portion can support the OIS moving portion relative to the fixed portion. For example, the support portion may include a tilt guide portion 1060. In other embodiments, the support portion may further include a rolling member (e.g., a ball member) or a sliding member (e.g., a shaft).

[0516] The bobbin 1110 is for housing a lens or lens barrel and may be located within the holder 1140. Alternatively, the bobbin 1110 may be located within the cover member 1300. The bobbin 100 may be located within the cover member 1300. The bobbin 1110 may be replaced with "lens holder" or "lens carrier".

[0517] The bobbin 1110 is movable in the optical axis direction. For example, due to the electromagnetic interaction between the coil 1120 and the magnet 1130, the bobbin 1110 can be moved in a first direction (e.g., the Z-axis direction). The coil 1120 and the magnet 1130 may be an AF drive unit that moves or drives the AF moving unit. The bobbin 1110 may also be included in the OIS moving unit 1100, and the bobbin 1110 may be tilted or rotated by a predetermined angle with respect to a first or second axis.

[0518] Referring to Figure 24, the bobbin 1110 may include an aperture 1101 for coupling with the lens module 1400. The aperture 1101 may be a hole or hollow that penetrates the bobbin 1110 along the optical axis. The shape of the aperture 1101 of the bobbin 1110 may match the shape of the lens module 1400 to which it is mounted or coupled, and may be, for example, circular, elliptical or polygonal.

[0519] Although not shown in Figure 20, the bobbin 1110 may include at least one stopper located on at least one of its top and bottom surfaces. The stopper of the bobbin 1110 may be a structure that protrudes from the top (or bottom) surface of the bobbin 1110 in a first direction or upward (or downward) direction, and can prevent the top (or bottom) surface of the bobbin 1110 from directly colliding with the inner surface of the top plate 1301 of the cover member 1300 (or the lower part of the holder 1140).

[0520] The bobbin 1110 may include a mounting portion 1115 for mounting or positioning the magnet 1130. For example, the mounting portion 1115 may be a groove recessed from the outer surface of the bobbin 1110.

[0521] Referring to Figure 25, the bobbin 1110 may include multiple sides 110A to 110D, or an outer side. For example, the bobbin 1110 may include a first side 1110A, a second side 1110B, a third side 1110C, and a fourth side 1110D.

[0522] For example, the second side surface 1110B may be opposite to the first side surface 1110A, or on the opposite side of the first side surface 1110A with respect 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 be opposite to the third side surface 1110C, or on the opposite side of the third side surface 1110C with respect to the optical axis OA. Figure 25 shows an example in which the bobbin 1110 has four sides, but other embodiments may include three or more sides.

[0523] For example, the mounting portion 1115 may be formed on the first side surface 1110A of the bobbin. For example, the lower part of the mounting portion 1115 may be closed and not open to the lower surface of the bobbin 1110. Also, the upper part of the mounting portion 1115 may be closed and not open to the upper surface of the bobbin 1110. In another embodiment, for example, the mounting portion 1115 may include an opening that opens to at least one of the upper or lower surfaces of the bobbin 1110.

[0524] The bobbin 1110 may include a housing portion 1112 for housing at least a portion of the rolling member 1021. For example, at least a portion of the housing portion 1112 may be located on the first side surface 1110A of the bobbin 1110. The housing portion 1112 may be a groove recessed from the outer surface (e.g., the first side surface 1110A) of the bobbin 1110. The housing portion 1112 may be replaced with "housing groove," "groove," or "guide groove." To reduce friction with the rolling member 1021, a lubricant (e.g., grease) may be placed in the housing portion 1112 of the bobbin 1110.

[0525] For example, the bobbin 1110 may include a first housing section 1112A for housing the rolling member 1021A, and a second housing section 1112B for housing the rolling member 1021B. For example, the mounting section 1115 may be positioned between the first housing section 1112A and the second housing section 1112B.

[0526] For example, the first housing section 1112A (or the second housing section 1112B) may include an opening that opens to the upper surface of the bobbin 1110. In other embodiments, the upper parts of the housing sections 1112A and 1112B may be closed and not open to the upper surface of the bobbin 1110. For example, the lower parts of the housing sections 1112A and 1112B may be closed and not open to the lower surface of the bobbin 1110. For example, the housing section 1112 may be formed to extend in the optical axis direction. For example, the housing section 1112 may extend in the optical axis direction so as to be formed between the upper and lower surfaces of the bobbin 1110.

[0527] For example, when viewed from above, the shape of the storage section 1112 may be triangular, but is not limited to this, and may be polygonal (e.g., quadrilateral, pentagon, etc.). Alternatively, for example, when viewed from above, the storage section 1112 may be V-shaped or U-shaped.

[0528] The magnet 1130 can be placed on, coupled to, or fixed to the bobbin 1110. For example, the magnet 1130 can be placed on or coupled to the first side surface 1110A of the bobbin 1110. For example, the magnet 1130 can be placed within or coupled to the mounting portion 1115 of the bobbin 1110. For example, the magnet 1130 can be placed between the first rolling member 1021A and the second rolling member 1021B.

[0529] The shape of the magnet 1130 may correspond to the shape of the first side surface 1110A of the bobbin 1110, for example, a rectangular parallelepiped shape. In another embodiment, for example, at least one of the ends of the magnet 1130 may be tapered.

[0530] For example, the magnet 1130 may include a first side surface 1013A facing the coil 1120 and a second side surface 1013B which is the opposite side of the first side surface 1013A. The first side surface 1013A of the magnet 1130 may be exposed from the first side surface 1110A of the bobbin 1110.

[0531] Furthermore, to improve 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 north and south poles, a second magnet including south and north poles, and a partition wall positioned between the first and second magnets. In this case, the partition wall is a substantially non-magnetic portion, includes a section with little polarity, may be filled with air or composed of a non-magnetic material, and may be referred to as a "neutral zone." For example, the first and second magnets may face each other in the direction of the optical axis, and the first and second magnets may be positioned such that their opposite polarities face each other in the direction of the optical axis.

[0532] In other embodiments, the magnet 1130 may be a bipolar magnet having an interface that naturally forms between two different polarities. For example, in other embodiments, the magnet 1130 may include one north pole and one south pole. For example, the magnet 1130 may be a magnet divided or arranged as a north pole and a south pole along the optical axis. In other embodiments, the magnet 1130 may be a bipolar magnet divided as a north pole and a south pole in a direction perpendicular to the optical axis.

[0533] The holder 1140 may be positioned inside the cover member 1300. The holder 1140 may include a cavity for housing 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 hollow to expose at least a portion of the bobbin 1110 (or lens module 1400). The opening 1030A of the holder 1140 may also expose the imaging area of ​​the image sensor 1810. The holder 1140 can be replaced with "housing." For example, the aperture 1030A may be located in the center or central region of the holder 1140. For example, the aperture 1030A of the holder 1140 may be a through hole or hollow that penetrates the holder 1140 in the direction of the optical axis. The aperture 1030A of the holder 1140 may have a shape corresponding to the shape of the bobbin 1110, such as a polygon (e.g., a square or octagon) or a circle (or ellipse), but is not limited to these, and can have various shapes.

[0534] The holder 1140 may include a plurality of side sections 1041A to 1041D. The holder 1140 is located between two adjacent side sections and may include a corner connecting the two adjacent side sections. The holder 1140 may include a first side section 1041A corresponding to or facing the first side section 1110A of the bobbin 1110, a second side section 1041B corresponding to or facing the second side section 1110B of the bobbin 1110, a third side section 1041C corresponding to or facing the third side section 1110C of the bobbin 110, and a fourth side section 1041D corresponding to or facing the fourth side section 1110D of the bobbin 1110.

[0535] The first side portion 1041A (or first side or first outer surface) of the holder 1140 may be located on the opposite side of the second side portion 1041B (or second side or second outer surface) of the holder 1140 with respect to the optical axis. Similarly, the third side portion 1041C (or third side or third outer surface) of the holder 1140 may be located on the opposite side of the fourth side portion 1041D (or fourth side or fourth outer surface) of the holder 1140 with respect to the optical axis. Each of the first to fourth side portions 1041A to 1041D of the holder 1140 may be positioned parallel to the corresponding side plate 302 of the cover member 1300.

[0536] Referring to Figures 26a and 26b, the holder 1140 may include a mounting portion 1142A for arranging the coil 1120. For example, the mounting portion 1142A may be located on or formed on the first side portion 1041A of the holder 1140. For example, the mounting portion 1142A may be a through-hole penetrating the first side portion 1041A of the holder 1140. Because the mounting portion 1142A is in the form of a through-hole, a portion of the holder 1140 may not be interposed between the coil 1120 and the magnet 1130, thereby increasing the electromagnetic force between the magnet 1130 and the coil 1120. Also, because a portion of the holder 1140 may not be interposed between the position sensor 1170 and the magnet 1130, the output of the position sensor 1170 can be increased, and the sensitivity of the position sensor 1170 can be improved. Furthermore, because a portion of the holder 1140 is not interposed between the coil 1120 and the magnet 1130, the size of the camera device can be reduced. In another embodiment, the mounting portion 1142A may be a groove recessed from the outer (or inner) surface of the first side portion 1041A of the holder 1140.

[0537] The holder 1140 may include a groove 1142 for accommodating at least a portion of the circuit board 1800, for example, at least a portion of the second substrate 1802. Since at least a portion of the second substrate 1802 is positioned within the groove 1142 of the holder 1140, the second substrate 1802 and the magnetic material 1082 can be prevented from protruding from the outer surface of the first side portion 1041A of the holder 1140, or from protruding excessively from the outer surface of the first side portion 1041A. That is, the second substrate 1802 and the magnetic material 1082 can protrude less than the sum of the thicknesses of the second substrate 1802 and the magnetic material 1082, with respect to the outer surface of the first side portion 1041A of the holder 1140. This prevents an increase in the size of the camera device 1200 in the direction perpendicular to the optical axis.

[0538] Referring to Figures 26a and 26b, the holder 1140 may include a housing 1116 for arranging or housing at least another portion of the rolling member 1021. For example, at least a portion of the housing 1116 may be located on the first side 1041A of the holder 1140. The housing 1116 may be a groove recessed from the inner surface of the holder 1140 (e.g., the inner surface of the first side 1041A). The housing 1116 may be replaced with "housing groove," "groove," or "guide groove." At least a portion of the housing 1116 of the holder 1140 may correspond to, face, or overlap with the housing 1112 of the bobbin 1110.

[0539] For example, the holder 1140 may include a first housing section 1116A for housing at least the other parts of the first rolling members 1021A; B1, B2, and a second housing section 1116B for housing at least the other parts of the second rolling members 1021B; B3, B4. For example, the mounting section 1142A of the holder 1140 may be located between the first housing section 1116A and the second housing section 1116B of the holder 1140.

[0540] For example, the first housing section 1116A (or the second housing section 1116B) may include an opening that opens to the upper surface of the holder 1140. In other embodiments, the upper part of the housing section 1116 may be closed and not open to the upper surface of the holder 1140. For example, the lower part of the housing section 1116 may be closed and not open to the lower surface of the holder 1140. For example, the housing section 1116 may be formed to extend in the optical axis direction. For example, the housing section 1116 may extend in the optical axis direction so as to be formed between the upper and lower surfaces of the holder 1140. For example, when viewed from above, the shape of the housing section 1116 of the holder 1140 may be triangular, but not limited to this, and may be polygonal (e.g., quadrilateral or pentagon). Or, for example, when viewed from above, the housing section 1116 may be V-shaped or U-shaped.

[0541] For example, when viewed from the optical axis direction or from above, the housing portion 1116 may face or overlap with 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 housing portion 1116.

[0542] The camera device 1200 may include a rolling member 1021 positioned between the bobbin 1110 and the holder 1140. The rolling member 1021 may be replaced with "ball member," "ball," or "ball bearing."

[0543] At least a portion of the rolling member 1021 can be in contact with the bobbin 1110 and the holder 1140, and by rolling or rotating between the bobbin 1110 and the holder 1140, it can support the movement of the bobbin 1110 in the optical axis direction. 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. Due to the rolling or rotating motion of the rolling member 1021, the bobbin 1110 can slide or move in the optical axis direction in contact with the rolling member 1021.

[0544] For example, the rolling member 1021 may be made of a metal, plastic, or resin material, but is not limited thereto. The rolling member 1021 may have a circular shape and a diameter large enough to support the movement of the bobbin 1110 in the optical axis direction.

[0545] For example, the rolling member 1021 may be positioned between the outer surface of the bobbin 1110 and the inner surface of the holder 1140. For example, the rolling member 1021 may be positioned between the first side surface 1110A of the bobbin 1110 and the first side portion 1041A of the holder 1140. For example, the rolling member 1021 may be positioned between the housing portion 1112 of the bobbin 1110 and the housing portion 1116 of the holder 1140. For example, at least a portion of the rolling member 1021 may be in contact with the housing portion 1112 of the bobbin 1110, and at least another portion of the rolling member 1021 may be in contact with the housing portion 1116 of the holder 1140.

[0546] 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. For example, the rolling member 1021 may include a first rolling member 1021A positioned between the first housing portion 1112A of the bobbin 1110 and the first housing portion 1116A of the holder 1140, and a second rolling member 1021B positioned between the second housing portion 1112B of the bobbin 1110 and the second housing 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 multiple balls B1, B2.

[0547] 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, B4. In other embodiments, the first rolling member 1021A and the second rolling member 1021B may each include one ball.

[0548] For example, the first rolling member 1021A and the second rolling member 1021B may each include three or more balls. For example, the first rolling member 1021A and the second rolling member 1021B may each 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 balls, and the diameter of the lowest ball may be larger than the diameter of the intermediate balls. Also, for example, the diameters of the highest ball and the lowest ball may be the same as each other. In other embodiments, the diameters of the highest ball, the lowest ball, and the intermediate ball may be the same as each other.

[0549] For example, the first rolling member 1021A and the second rolling member 1021B may each include a first ball (highest ball), a second ball (lowest ball), and a third ball (intermediate 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 as each other.

[0550] For example, the diameters of the first ball and the second ball may be between 0.85 mm and 0.95 mm, respectively, and the diameter of the third ball may be between 0.75 mm and 0.85 mm.

[0551] In another embodiment, the first rolling member 1021A and the second rolling member 1021B may each include four balls, the diameter of the largest ball and the diameter of the smallest ball may be 0.85 mm or more and 0.95 mm or less, respectively, and the diameter of each of the two intermediate balls may be 0.75 mm or more and 0.85 mm or less.

[0552] When viewed from above, the coil 1120 and magnet 1130 may be positioned between the first rolling member 1021A and the second rolling member 1021B. This prevents the bobbin 1110 from tilting as it moves in the optical axis direction, allowing the rolling member 1021 to stably support the bobbin 1110 and improving the reliability of autofocus.

[0553] In other embodiments, the first rolling member 1021A and the second rolling member 1021B may be in the form of a shaft or a roller, respectively. In other embodiments, the ball members 1021A and 1021B may be replaced with sliding members (e.g., a shaft) or rollers.

[0554] The camera device 1200 may include a magnetic body 1082 that acts attractively to 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 located in the holder 1140. In another embodiment, the magnetic body 1082 may be located in the housing 1210.

[0555] The magnetic material 1082 may be composed of a substance that adheres to a magnet. For example, the magnetic material 1082 may be composed of a metallic material. Or, for example, the magnetic material 1082 may be composed of a magnetic metallic material. Or, for example, the magnetic material 1082 may be a magnet.

[0556] The magnetic material 1082 can be replaced with "yoke" or "metal plate." The magnetic material 1082 can also play a role in improving or increasing the electromagnetic force between the magnet 1130 and the coil 1120.

[0557] Since the magnet 1130 is placed on the bobbin 1110 and the magnetic material 1082 is placed 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 where the magnetic material 1082 is located. The attractive force between the magnetic material 1082 and the magnet 1130 allows the bobbin 1110 and the holder 1140 to press against the rolling member 1021, thereby stably supporting the bobbin 1110. The magnetic material 1082 and the magnet 1130 may 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, as the bobbin 1110 moves in the optical axis direction. In other words, the attractive force between the magnet 1130 and the magnetic material 1082 allows the rolling member 1021 to stably support the bobbin 1110 relative to the holder 1140.

[0558] In another embodiment, the magnet 1130 may be located in the holder 1140 and the coil 1120 may be located in the bobbin 1110. For example, the magnetic material 1082 may be located in the holder 1140 together with the magnet 1130. For example, the magnet 1130 may be located between the magnetic material 1082 and the coil 1120. In yet another embodiment, the magnetic material 1082 may be located in the bobbin 1110 together with the coil 1120, facing the magnet 1130 located in the holder 1140. In yet another embodiment, the camera device 1200 may further include a conductive member for electrically connecting the coil 1120 located in the bobbin 1110 to the second substrate 1802 of the circuit board 1800.

[0559] Referring to Figure 26b, the holder may include a mounting section 1045A for mounting or positioning the filter 1610. The mounting section 1045A may be located on or formed on the lower surface of the holder 1140. For example, the mounting section 1045A may be a groove recessed from the lower surface of the holder 140. For example, the mounting section 1045A may include a bottom surface 1005A having a step in the optical axis direction from the lower surface of the holder 1140 and a side surface 5B connecting the lower surface of the holder 1140 and the bottom surface 1005A of the mounting section 1045A. For example, the opening 1030A may penetrate the bottom surface 1005A of the mounting section 1045A.

[0560] The holder 1140 may include a recess 1045B positioned or formed in the corner region of the inner surface of the mounting portion 1045A. The recess 1045B may have a structure that is recessed toward the corner region of the inner surface of the mounting portion 1045A from the optical axis. The recess 1045B can prevent the adhesive (e.g., UV epoxy) used to bond or attach the filter 1610 to the mounting portion 1045A from overflowing outside the mounting portion 1045A.

[0561] The holder 1140 may include relief grooves 1046 to avoid spatial interference with the circuit element 1815. For example, the relief grooves 1046 may be located or formed on the lower surface of the holder 1140. For example, the relief grooves 1046 may be recessed from the lower surface of the holder 1140. For example, the relief grooves 1046 may correspond to, face, or overlap with the circuit element 1815 in the optical axis direction. For example, the relief grooves 1046 may be located between the mounting portion 1045A and the edge of the lower surface of the holder 1140. For example, the relief grooves 1046 may include a first relief groove 1046A and a second relief groove 1046B located on opposite sides of each other with respect to the mounting portion 1045A or the filter 1610. In other embodiments, the relief grooves 1046 may include four relief grooves located between the opening 1030A and the four edges of the holder 1140.

[0562] The holder 1140 may include a groove 1047 corresponding to a projection 1216 of the sensor base 1270. The projection 1216 of the sensor base 1270 and the groove 1047 of the holder 1140 can serve as guides for easy assembly of the sensor base 1270 and the holder 1140, increasing the bonding area and improving the bonding force between the sensor base 1270 and the holder 1140.

[0563] For example, the groove 1047 may be recessed from the lower surface of the holder 1140. For example, the groove 1047 may be located 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 projection 1216 of the sensor base 1270. The holder 1140 may also include a groove 1048 or hole corresponding to the projection 1017 of the sensor base 1270. For example, the projection 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 located 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.

[0564] In other embodiments, the holder 1140 may include a projection protruding from the lower surface of the holder 1140 instead of the groove 1047. The sensor base 1270 may include a groove recessed from the upper surface of the sensor base 1270 and coupled with the projection of the holder 1140 instead of the projection 1216. In other embodiments, the projection 1017 may be formed in the holder 1140 and the groove 1048 may be formed in the sensor base 1270.

[0565] The camera device 1200 may include a filter 1610 that is positioned on or coupled to the holder 1140. For example, the filter 1610 may be positioned below the holder 1140. The filter 1610 may be positioned between the lens module 1400 and the image sensor 1810. For example, the filter 1610 may be coupled to the lower surface of the holder 1140. For example, the filter 1610 may be positioned on the mounting portion 1045A of the holder 1140.

[0566] The filter 1610 can serve to block light of a specific frequency band from entering the image sensor 1810 from the light passing through the lens module 1400. For example, the filter 1610 may be an infrared cut filter. For example, the filter 1610 may be arranged parallel to a plane perpendicular to the optical axis OA.

[0567] The filter 1610 can be bonded to the holder 1140 (or mounting portion 1045A) by an adhesive (not shown). For example, the edge region of the filter 1610 can be bonded to the bottom surface of the mounting portion 1045A.

[0568] For example, the adhesive may be epoxy, thermosetting adhesive, or UV-curing adhesive. For example, at least a portion of the filter 1610 may correspond to, face, or overlap with the lens module 1400 and / or image sensor 1810 in the optical axis direction.

[0569] The sensor base 1270 may be located below the holder 1140. The sensor base 1270 may be located below the filter 1610. For example, the sensor base 1270 may be located below the image sensor 1810. For example, the sensor base 1270 may be located below the circuit board 1800.

[0570] The sensor base 1270 may be coupled with the holder 1140. The sensor base 1270 may be referred to as the "holder." The holder 1140 may be referred to as the "first housing" (or "first holder"), and the sensor base 1270 may be referred to as the "second housing" (or "second holder"). Alternatively, the holder 1140 and the sensor base 1270 may not be distinguished and may be referred to as a single term, such as "housing" (or "holder"). In other embodiments, the sensor base 1270 and the holder 1140 may be formed integrally. In yet another embodiment, the sensor base 1270, the holder 1140, and at least two of the support member 1064 may be formed integrally.

[0571] For example, the sensor base 1270 may include a projection 1216 that protrudes from the top surface. The projection 1216 can be replaced with the term "column".

[0572] For example, the projection 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 projection 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 projection 1216 may be bonded to the groove 1047 of the holder 1140. For example, at least a portion of the projection 1216 may be bonded to the groove 1047 of the holder 1140 by an adhesive.

[0573] For example, the sensor base 1270 may include a main body 1270A and a projection 1216 protruding from the upper surface of the main body 1270A. For example, the main body 1270A may have a shape corresponding to the first substrate 1801 of the circuit board 1810. For example, the main body 1270A may have a polyhedron shape, for example, a hexahedron shape. For example, the projection 1216 may be located in the corner region of the upper surface of the main body 1270A. For example, the projection 1216 may include four projections 1216A to 1216D located in the four corner regions of the upper surface of the main body 1270. Also, for example, the holder 1140 may include four grooves 1047 corresponding to the four projections 1216A to 1216D. In another embodiment, the housing 1210 may include at least one projection located in at least one of the four corner regions of the upper surface of the main body 1270, and the holder 1140 may include at least one groove 1048 corresponding to at least one projection of the housing 1210.

[0574] The sensor base 1270 or main body 1270A may include side portions 1051A to 1051D that correspond to, oppose, or overlap with the side portions 1041A to 1041D of the holder 1140. The sensor base 1270 may include corners positioned between the side portions 1051A to 1051D. For example, the sensor base 1270 may include a first corner to a fourth corner.

[0575] The camera device 1200 may include a gyro sensor (not shown) located on the circuit board 1800. For example, the gyro sensor may be located on a first substrate 1801 of the circuit board 1800. For example, the gyro sensor may be located, coupled, or fixed to the underside of the first substrate 1801. For example, the gyro sensor outputs rotational angular velocity information due to the movement of the camera device 1200. For example, the gyro sensor may be implemented as a two-axis or three-axis gyro sensor, or as an angular velocity sensor. For example, the gyro sensor may be electrically or electrically connected to the first substrate 1801.

[0576] In other embodiments, the sensor base 1270 may include a housing for which a gyro sensor is positioned or to avoid spatial interference with the gyro sensor 820. For example, the housing may be a through-hole penetrating the sensor base 1270 in the optical axis direction, or a groove recessed from the upper surface of the sensor base 1270 or the upper surface of the main body 1270A. In this case, the housing may include an opening that opens to the outer surface of the sensor base 1270.

[0577] The sensor base 1270 may house the control unit 1830 or include a housing 1255 for housing the control unit 1830. The housing 1255 may be a groove recessed from the upper surface of the sensor base 1270 or the upper surface of the main body 1270A. In other embodiments, the housing 1255 may be a through-hole penetrating the sensor base 1270 or the main body 1270A in the optical axis direction.

[0578] The sensor base 1270 may include mounting sections 1274A and 1274B for arranging the coils 1230. The mounting sections 1274A and 1274B may be arranged or formed on the upper surface of the sensor base 1270. For example, the mounting sections 1274A and 1274B may be grooves recessed from the upper surface of the sensor base 1270. For example, the sensor base 1270 may include a first mounting section 1274A for arranging or mounting a first coil unit 1230A and a second mounting section 1274B for arranging or mounting a second coil unit 1230B.

[0579] For example, the first mounting portion 1274A may be formed adjacent to or in contact with any one of the protrusions 1216A to 1216D of the sensor base 1270 (e.g., 1216C). For example, the first mounting portion 1274A may be a groove formed on the upper surface of the sensor base 1270 adjacent to the third protrusion 1216C of the sensor base 1270. For example, the first mounting portion 1274A may include an opening that opens to the outer surface of a side portion (e.g., 1051B, 1051D) adjacent to the third protrusion 1216C of the sensor base 1270. In other embodiments, the first mounting portion 1274A may be spaced apart from the outer surface of the side portion (e.g., 1051B, 1051D) of the sensor base 1270 and may not include an opening that opens to the outer surface of the side portion 1051B, 1051D.

[0580] For example, the second mounting portion 1274B may be formed adjacent to or in contact with any one of the other projections 1216A to 1216D of the sensor base 1270 (e.g., 1216D). For example, the second mounting portion 1274B may be a groove formed on the upper surface of the sensor base 1270 adjacent to the fourth projection 1216D of the sensor base 1270. For example, the second mounting portion 1274B may include an opening that opens to the outer surface of a side portion (e.g., 1051B, 1051C) of the sensor base 1270 adjacent to the fourth projection 1216D. In other embodiments, the second mounting portion 1274B may be spaced apart from the outer surface of the side portion (e.g., 1051B, 1051C) of the sensor base 1270 and may not include an opening that opens to the outer surface of the side portion 1051B, 1051C.

[0581] In another embodiment, the mounting portion 1274 of the sensor base 1270 may be formed corresponding to the position where the coil 1230 is placed.

[0582] In other embodiments, the mounting portions 1274A and 1274B may be through-holes. For example, at least one of the first mounting portion 1274A and the second mounting portion 1274B may be a hole or through-hole penetrating the sensor base 1270 in the optical axis direction. In this case, a portion 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. Also, a portion of the sensor base 1270 may not be interposed between the position sensor 1240 and the magnet 1310, thereby increasing the output of the position sensor 1240 and improving the sensitivity of the position sensor 1240. Furthermore, a portion of the sensor base 1270 may not be interposed between the position sensor 1240 and the magnet 1310, thereby reducing the height of the camera device.

[0583] In other embodiments, the mounting portions 1274A and 1274B may be in the form of relief portions that avoid spatial interference with the entire coil 1230.

[0584] The sensor base 1270 may include grooves 1029 in which at least a portion (e.g., projections 1065) of the tilt guide portion 1060 is positioned or accommodated. The grooves 1029 may be formed on 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. For example, the number of grooves 1029 may be the same as the number of projections 1065 of the tilt guide portion 1060.

[0585] For example, groove 1029 may include two grooves 1029A and 1029B that are spaced apart from each other. For example, the two grooves 1029A and 1029B may be spaced apart from each other in the first axial direction (see Figure 35a). For example, the extension 1217 of the sensor base 1270 may be positioned between the two grooves 1029A and 1029B of the sensor base 1270.

[0586] The groove 1029 may contact the projection 1065 of the tilt guide portion 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. At least one side surface may be an inclined surface. For example, the groove 1029 may include a bottom surface and a plurality of inclined surfaces. The shapes of the inclined surfaces of the groove 1029 may be identical to each other. In other embodiments, at least one of the inclined surfaces of the groove 1029 may have a different shape from the other inclined surfaces.

[0587] Referring to Figure 26a, a groove 1212A may be formed in the projection 1216 of the sensor base 1270 into which at least a portion of the first substrate 1801 of the circuit board 1800 is inserted or positioned. For example, the corner of the first substrate 1801 may be inserted into or coupled to the groove 1212A of the projection 1216 of the sensor base 1270. For example, the groove 1212A may be formed on the side of the projection 1216 facing the corner of the circuit board 1800. In addition, a groove 1083 may be formed in at least one corner of the circuit board 1800 for insertion into or coupling to the groove 1212A of the projection 1216. The groove 1212A of the projection 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 serve to prevent the first substrate 1801 from rotating or detaching from the sensor base 1270.

[0588] The circuit board 1800 can be placed on, coupled to, or fixed to the sensor base 1270. For example, the circuit board 1800 can be coupled to the sensor base 1270 by adhesive or a fixing member.

[0589] The circuit board 1800 may be placed on, coupled to, or fixed to the main body 1270A of the sensor base 1270. The circuit board 1800 may include at least one of a rigid printed circuit board, a flexible printed circuit board, or a rigid-flexible printed circuit board. 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 replaced with "board portion," "board," or "printed circuit board."

[0590] For example, the circuit board 1800 may include a first substrate 1801 (or "first region") which is placed on, coupled to, or fixed to the sensor base 1270. For example, the first substrate 1801 may be placed on, coupled to, or fixed to the body 1270A of the sensor base 1270. For example, the lower surface of the first substrate 1801 may be coupled to the upper surface of the sensor base 1270 or the upper surface of the body 1270A. For example, the lower surface of the first substrate 1801 may be coupled to the upper surface of the sensor base 1270 or the upper surface of the body 1270A by adhesive.

[0591] The circuit board 1800 may include a second board 1802 (or "second region") which is connected to the first board 1801 and is positioned, coupled, or fixed to the holder 1140. For example, the second board 1802 may be positioned, coupled, or fixed to the first side portion 1041A of the holder 1140.

[0592] In Figure 26a, the circuit board 1800 includes one second board, but in other embodiments, the circuit board 1800 may include a plurality of second boards arranged on at least one of the sides of the holder 1140.

[0593] For example, the second substrate 1802 may be connected to the 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 portion 1041A of the holder 1140. For example, the second substrate 1802 may be extended upward from the first substrate 1801.

[0594] 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.

[0595] 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.

[0596] 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 placed between two adjacent conductive layers. For example, a flexible printed circuit board may include a single conductive layer (or circuit pattern), a first insulating layer placed on the conductive layer, and a second insulating layer placed beneath 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 placed between the first and second conductive layers, a second insulating layer placed on the first conductive layer, and a third insulating layer placed beneath the second conductive layer.

[0597] The image sensor 1810 may be located on the first substrate 1801. The image sensor 1810 may be located in the optical axis direction, opposite to, or overlapping with the lens module 1400 and / or filter 1610. For example, the image sensor 1810 may be located on the top surface of the circuit board 1800. For example, the image sensor 1810 may be located on the top surface of the first substrate 1801.

[0598] The image sensor 1810 may include a sensor surface for sensing light. For example, the sensor surface may include an imaging area. Here, the imaging area may be replaced with an effective area, a light-receiving area, or an active area. For example, the imaging area may include multiple pixels on which an image is formed. The imaging area may correspond to, face, or overlap with the lens module 1400 and / or filter 1610 in the optical axis direction.

[0599] The image sensor 1810 can be electrically or electrically connected to the first substrate 1801. For example, the image sensor 1810 can be electrically connected to the first substrate 1801 by a conductive member, such as a wire (not shown). For example, the first substrate 1801 of the circuit board 1800 may include a wire electrically connected to the image sensor 1810 and at least one pad or terminal (not shown) electrically connected to it. For example, the pad or terminal electrically connected to the wire may be located on the upper surface of the first substrate 1801.

[0600] The camera device 1200 may include a circuit element 1815 arranged 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 resistor), an active element (e.g., a sensor, memory, driver IC), or a circuit pattern. For example, to avoid spatial interference with the image sensor 1810, the circuit element 1815 may be arranged between the image sensor 1810 and the edge (e.g., side) of the first substrate 1801.

[0601] The camera device 1200 may include a control unit 1830 located on a circuit board 1800. For example, the control unit 1830 may be a driver IC. For example, the control unit 1830 may be located on a first board 1801. For example, the control unit 1830 may be located beneath the first board 1801. For example, the control unit 1830 may be located, coupled, or fixed to the underside of the first board 1801. For example, the control unit 1830 may be electrically or electrically connected to the first board 1801.

[0602] For example, the control unit 1830 can be electrically or electrically connected to the coil 1120 and can supply a drive signal to the first coil 1120. The control unit 1830 can be electrically or electrically connected to the coil units 1230A and 1230B of the coil 1230 and can supply a first drive signal to the first coil unit 1230A and a second drive signal to the second coil unit 1230B.

[0603] The control unit 1830 may be electrically or electrically connected to the position sensor 1170. The control unit 1830 may also be electrically or electrically connected to the position sensor 1240.

[0604] For example, the control unit 1830 can receive the output signal from the position sensor 1170 and use the output signal from the position sensor 1170 to control the drive signal (e.g., drive current) supplied to the coil 1120.

[0605] Furthermore, the control unit 1830 can receive the output signal of the position sensor 1240 and control the drive signal (e.g., drive current) supplied to the coil 1230 using the output signal of the position sensor 1240. For example, the control unit 1830 can receive the output signal of the first sensor 1240A and control the first drive signal (e.g., first drive current) supplied to the first coil unit 1230A using the output signal of the first sensor 1240A. Also, the control unit 1830 can receive the output signal of the second sensor 1240B and control the second drive signal (e.g., second drive current) supplied to the second coil unit 1230B using the output signal of the second sensor 1240B.

[0606] Coils 1120 and 1230 can be placed, coupled, or fixed to the circuit board 1800. For example, coil 1120 can be conductively or electrically connected to the circuit board 1800 (e.g., a second board 1802) by conductive adhesive or solder. For example, coil 1230 can be conductively or electrically connected to the circuit board 1800 (e.g., a first board 1801) by conductive adhesive or solder.

[0607] The first coil unit 1230A and the second coil unit 1230B may be positioned on or coupled to the first substrate 1801, and may be electrically or electrically connected to the first substrate 1801. Referring to Figure 26b, for example, the first coil unit 1230A and the second coil unit 1230B may be positioned on, coupled to, or fixed to the underside of the first substrate 1801. For example, the first coil unit 1230A and the second coil unit 1230B may be positioned between the first substrate 1801 and the sensor base 1270.

[0608] For example, the first coil unit 1230A and the second coil unit 1230B may be positioned adjacent to two adjacent corners of the first substrate 1801. For example, for diagonal drive, the first coil unit 1230A may be positioned adjacent to one corner of the first substrate 1801 corresponding to the protrusion 1216C of the sensor base 1270 (or any corner of the sensor base 1270), and the second coil unit 1230B may be positioned adjacent to the other corner of the first substrate 1801 corresponding to the protrusion 1216D of the sensor base 1270 (or any other corner of the sensor base 1270). For example, the first coil unit 1230A may be positioned adjacent to the protrusion 1216C of the sensor base 1270, and the second coil unit 1230B may be positioned adjacent to the protrusion 1216D of the sensor base 1270.

[0609] In other embodiments, the first coil unit 1230A and the second coil unit 1230B may be positioned adjacent to two adjacent sides of the four sides of the first substrate 1801.

[0610] The coil 1120 can move the AF moving part (e.g., a bobbin) in the optical axis direction through interaction with the magnet 1130. The coil 1120 may be placed in the holder 1140.

[0611] The coil 1120 may be positioned 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 positioned in 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 positioned on the first side 1041A of the housing 130. The coil 1120 may be positioned within the mounting portion 1142A of the holder 1140.

[0612] For example, the coil 1120 may be hollow or contain holes. For example, the coil 1120 may have a ring shape or a closed curve shape. For example, the coil 1120 may be a ring shape wound around a straight line 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 a ring shape in which the length in the lateral direction (or third direction) is longer than the length in the vertical direction (or optical axis direction).

[0613] A drive signal can be applied to the coil 1120 in order to generate an electromagnetic force through electromagnetic interaction with the magnet 1130. For example, a drive signal can be applied to the coil 1120 from the circuit board 1800 or the control unit 1830. In this case, the drive signal supplied to the coil 1120 may be DC and may be in the form of voltage or current. In another embodiment, for example, the drive signal provided to the coil 1120 may include at least one of a DC signal and an AC signal.

[0614] The coil 1120, to which a drive signal is supplied, can electromagnetically interact with the magnet 1130 located on the bobbin 1110, and the electromagnetic force resulting from the electromagnetic interaction between the coil 1120 and the magnet 1130 can move the AF moving part in a first direction. The control unit 1830 adjusts the magnitude and / or direction of the drive signal (e.g., drive current) to control the movement of the AF moving part in the first direction, thereby enabling the autofocus function to be performed.

[0615] For AF feedback drive, the camera device 1200 may include a position sensor 1170. The position sensor 1170 can detect the position or displacement of the bobbin 1110 in the optical axis direction. For example, the position sensor 1170 can detect a magnet 1130 placed on the bobbin 1110. In another embodiment, a sensing magnet opposite the position sensor 1170 may be placed on the bobbin separately from the magnet 1130, and the position sensor 1170 can detect the displacement of the bobbin by detecting the sensing magnet or the magnetic field of the sensing magnet.

[0616] For example, the position sensor 1170 may be located in the holder 1140. For example, the position sensor 1170 may be located in the first side portion 1041A of the holder 1140. For example, the position sensor 1170 may be located within the mounting portion 1142A of the holder 1140. For example, the position sensor 1170 may be located within the hollow portion of the coil 1120. In another embodiment, the position sensor 1170 may be located outside the hollow portion of the coil 1120.

[0617] For example, the position sensor 1170 may be coupled to the circuit board 1800. For example, it may be coupled to the circuit board 1800 by conductive adhesive or solder. For example, the position sensor 1170 may be electrically or conductively connected to the second substrate 1802. For example, the position sensor 1170 may be electrically or conductively connected to the second substrate 1802 by conductive adhesive or solder.

[0618] For example, the position sensor 1170 may be positioned, coupled, or fixed to the first surface of the second substrate 1802. For example, the position sensor 1170 may correspond to, face, or overlap with the magnet 1130 in a direction perpendicular to the optical axis or in a second direction.

[0619] The position sensor 1170 can detect the displacement of the bobbin 1110 in the optical axis direction. For example, the position sensor 1170 can detect the magnetic field or the strength of the magnetic field of the magnet 1130 attached to the bobbin 1110 in response to the movement of the bobbin 1110, and output an output signal.

[0620] For example, the position sensor 1170 may be a Hall sensor. In this case, the position sensor 1170 may include two input terminals to which a drive signal is applied and two output terminals to which an output signal is output. The circuit board 1800 may be electrically 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 drive 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.

[0621] In other embodiments, the position sensor 1170 may be implemented as a driver IC that includes a Hall sensor. For example, if the position sensor 1170 is a driver IC that includes a Hall sensor, the position sensor 1170 can send and receive data to and from the outside using protocol-based data communication, such as I2C communication.

[0622] For example, if the position sensor 1170 is a driver IC that includes a Hall sensor, the position sensor 1170 may include first and second terminals to which power or drive signals are input, a third terminal for a clock signal, a fourth terminal for a data signal, and fifth and sixth terminals for supplying drive signals to the coil 1120. The first to sixth terminals of the position sensor 1170 may be electrically or electrically connected to the circuit board 1800.

[0623] The coil 1230 interacts with the magnet 1310 located in the housing 1210, which is the fixed part, to tilt the OIS moving part with respect to the first or second axis, or to rotate it by a predetermined angle.

[0624] Coil 1230 may be opposite, corresponding to, or overlapping with magnet 1310 in the optical axis direction. Coil 1230 may include a first coil unit 1230A that corresponds to, opposes, or overlaps with the first magnet unit 1310A in the optical axis direction, and a second coil unit 1230B that corresponds to, opposes, or overlaps with the second magnet unit 1310B in the optical axis direction. For example, coil 1230 may not overlap with magnet 1310 in a direction perpendicular to the optical axis.

[0625] For example, coil 1230 may be positioned below coil 1120. For example, the first coil unit 1230A may be positioned within the first mounting portion 1274A of the sensor base 1270, and the second coil unit 1230B may be positioned within the second mounting portion 1274B of the sensor base 1270.

[0626] For example, the first coil unit 1230A and the second coil unit 1230B may each contain a hollow or hole. For example, the first coil unit 1230A and the second coil unit 1230B may each have a ring shape or a closed curve shape. For example, the first coil unit 1230A and the second coil unit 1230B may each have a ring shape wound around a straight line parallel to the optical axis OA and perpendicular to the upper surface of the sensor base 1270 or the upper surface of the main body 1270A.

[0627] For example, referring to Figure 35a, the first coil unit 1230A may have a ring shape in which the length in the lateral direction (or the direction parallel to the second axis) is longer than the length in the vertical direction (or the direction parallel to the first axis). For example, the second coil unit 1230B may have a ring shape in which the length in the vertical direction (for example, the direction parallel to the first axis) is longer than the length in the lateral direction (or the direction parallel to the second axis).

[0628] For OIS feedback drive, the camera device 1200 may include a position sensor 1240. The position sensor 1240 may detect the displacement or angular displacement of the OIS moving unit 1100 due to tilt or rotation of the OIS moving unit 1100. The position sensor 1240 may detect the magnetic field of the magnet 1310.

[0629] 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 detect the first magnet unit 1310A (or the magnetic field of the first magnet unit 1310A). For example, the first sensor 1240A may detect an angle tilted with respect to the second axis of the OIS moving part 1100. In other embodiments, the first sensor 1240A may not overlap with the first magnet unit 1310A and the second magnet unit 1310B in the optical axis direction.

[0630] 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 detect the second magnet unit 1310B (or the magnetic field of the second magnet unit 1310B). For example, the second sensor 1240B may detect the angle at which the OIS moving part 1100 is tilted with respect to the first axis. In other embodiments, the second sensor 1240B may not overlap with the second magnet unit 1310B in the optical axis direction.

[0631] For example, the first sensor 1240A and the second sensor 1240B may be placed on, coupled to, or fixed to the first substrate 1801 of the circuit board 1800. For example, the first sensor 1240A and the second sensor 1240B may be electrically or electrically connected to the first substrate 1801.

[0632] For example, the first sensor 1240A may be located inside the hollow (or hole) of the first coil unit 1230A, and the second sensor 1240B may be located inside the hollow (or hole) of the second coil unit 1230B. In other embodiments, the first sensor 1240A may be located outside the hollow (or hole) of the first coil unit 1230A, and the second sensor 1240B may be located outside the hollow (or hole) of the second coil unit 1230B.

[0633] For example, the first sensor 1240A and the second sensor 1240B may each be a Hall sensor including a first input terminal, a second input terminal, and a first output terminal and a second output terminal. For example, the first input terminal and the second input terminal and the first output terminal and the second output terminal of the first sensor 1240A may be electrically or electrically connected to the first substrate 1801, and the first input terminal and the second input terminal and the first output terminal and the second output terminal of the second sensor 1240B may also be electrically or electrically connected to the first substrate 1801.

[0634] For example, the first circuit board 1801 or the control unit 1830 may supply or apply a first drive signal to the first input terminal and the second input terminal of the first sensor 1240A. The first sensor 1240A outputs a first output signal, which can be transmitted to the first circuit board 1801 or the control unit 1830. The first output signal can be output from the first output terminal and the second output terminal of the first sensor 1240A.

[0635] For example, the first board 1801 or the control unit 1830 may supply or apply a second drive signal to the first input terminal and the second input terminal of the second sensor 1240B. The second sensor 1240B outputs a second output signal, which may be transmitted to the first board 1801 or the control unit 1830. The second output signal may be output from the first output terminal and the second output terminal of the second sensor 1240B.

[0636] The control unit 1830 can control the first drive signal supplied to the first coil unit 1230A and the second drive signal supplied to the second coil unit 1230B using the first output signal of the first sensor 1240A and the output signal of the second sensor 1240B.

[0637] In other embodiments, the first sensor 1240A and the second sensor 1240B may each be a driver IC including a Hall sensor. The description relating to embodiments in which the position sensor 1170 is a driver IC including a Hall sensor may be applied or applied by analogy to embodiments in which the first sensor 1240A and the second sensor 1240B are driver ICs including Hall sensors.

[0638] The camera device 1200 may include a magnetic body 1082 positioned opposite at least one of the coil 1120 and the magnet 1130. For example, the magnetic body 1082 may be positioned on the holder 1140 or on the second substrate 1802 of the circuit board 1800. For example, the magnetic body 1082 may correspond to, oppose, or overlap with the magnet 1130 in a second direction. Alternatively, for example, the magnetic body 1082 may be positioned corresponding to, oppose, or overlap with the coil 1120 in a second direction. For example, the coil 1120 may be positioned on the first surface of the second substrate 1802 opposite to the magnet 1130, and the magnetic body 1082 may be positioned on the second surface 1802 opposite to the first surface of the second substrate 1802. The magnetic body 1082 may be bonded, attached, or fixed to the second substrate 1802 by an adhesive.

[0639] The camera device 1200 may include a heat dissipation member (not shown) coupled to at least one of the circuit board 1800 or the sensor base 1270. For example, the heat dissipation member may be positioned below the circuit board 1800. For example, the heat dissipation member may be positioned between the circuit board 1800 and the sensor base 1270. The heat dissipation member may be a plate-like member having a predetermined thickness and hardness. The heat dissipation member can also release heat generated from the heat source of the circuit board 1800 to the outside, thereby improving heat dissipation efficiency. For example, the heat dissipation member may be made of a metal material or a metal plate.

[0640] Referring to Figures 29a and 29b, the housing 1210 may include a cavity for housing the OIS moving part 1100. For example, the housing 1210 may have a shape corresponding to the OIS moving part 1100, such as the holder 1140 or the sensor base 1270, such as a polygon (e.g., quadrilateral or octagon) or a circle (or ellipse), but is not limited to these, and can have various shapes. The housing 1210 may be replaced with "base" or "frame".

[0641] The housing 1210 may include a number of sides 1071A to 1071D corresponding 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 a corner located between two adjacent sides.

[0642] Furthermore, the housing 1210 may include a lower section 1042 (or bottom plate) located below the side sections 1071A to 1071D. The lower section 1042 may be connected to the underside of the side sections 1071A to 1071D. For example, the lower section 1042 may be replaced with "bottom," "bottom surface," or "body." For example, the side sections 1071A to 1071D may protrude upward from the lower section 1042.

[0643] The housing 1210 may include a first side portion 1071A corresponding to the first side portion 1041A of the holder 1140, an opposing or overlapping first side portion 1071B corresponding to the second side portion 1041B of the holder 1140, an opposing or overlapping second side portion 1071B corresponding to the third side portion 1041C of the holder 1140, an opposing or overlapping third side portion 1071C, and a fourth side portion 1071D corresponding to the fourth side portion 1041D of the holder 1140, an opposing or overlapping fourth side portion 1071D.

[0644] The first side portion 1071A (or first side or first outer side) of the housing 1210 may be located opposite the second side portion 1071B (or second side or second outer side) of the housing 1210, and the third side portion 1071C (or third side or third outer side) of the housing 1210 may be located opposite the fourth side portion 1071D (or fourth side or fourth outer side) of the housing 1210. For example, the first to fourth sides 1071A to 1071D of the housing 1210 may each be arranged parallel to any one of the corresponding side plates 1302 of the cover member 1300.

[0645] The housing 1210 may include a step 1411 located at the bottom of at least one of the side portions 1071A to 1071D. For example, the step 1411 may project 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 1411 may face or overlap with the side plate 1302 of the cover member 1300 in the direction of the optical axis. For example, the step 1411 may be bonded to the side plate 1302 of the cover member 1300 by adhesive.

[0646] The housing 1210 may include mounting sections 1141A and 1141B for arranging the magnets 1310. For example, the mounting sections 1141A and 1141B may be groove shapes formed in the lower part 1042 of the housing 1210. In other embodiments, the mounting sections 1141A and 1141B may be through holes penetrating the lower part 1042 of the housing 1210.

[0647] The housing 1210 may include a first mounting section 1141A for arranging the first magnet unit 1310A, and a second mounting section 1141B for arranging the second magnet unit 1310B. For example, the first mounting section 1141A may be located in or formed in a first region of the lower part 1042 of the housing 1210 adjacent to any one of the four corners of the housing 1210. For example, any one of the aforementioned corners of the housing 1210 may correspond to or be adjacent to a protrusion 1216C of the sensor base 1270.

[0648] For example, the second mounting portion 1141B may be located or formed in a second region of the lower part 1042 of the housing 1210 adjacent to any other of the four corners of the housing 1210. For example, the other corner of the housing 1210 may correspond to or be adjacent to the protrusion 1216D of the sensor base 1270.

[0649] In other embodiments, the first and second mounting sections may be positioned in locations corresponding to the positions where the coil units 1230A, 1230B and the magnet units 1310A, 1310B are located. For example, in other embodiments, the first mounting section may be formed adjacent to a first (or second) side of the housing 1210, and the second mounting section may be formed adjacent to a third (or fourth) side of the housing 1210.

[0650] The magnet 1310 may be positioned in or coupled to the housing 1210. For example, the magnet 1310 may include a first magnet unit 1310A and a second magnet unit 1310B positioned in the lower part 1042 of the housing 1210. For example, the magnet 1310 may be positioned below the coil 1230.

[0651] For example, the first magnet unit 1310A may be arranged to correspond to, face, or overlap with the first coil unit 1230A in the optical axis direction. The second magnet unit 1310B may be arranged to correspond to, face, or overlap with the second coil unit 1230B in the optical axis direction.

[0652] For example, the first magnet unit 1310A and the second magnet unit 1310B may be offset in the first axial direction (or parallel to the first axis) or the second axial direction (or parallel to the second axis). 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 positioned in the housing 1210 such that they do not overlap each other in the direction parallel to the first axis or parallel to the second axis. For example, the first magnet unit 1310A and the second magnet unit 1310B may be positioned in the lower part 1042 of the housing 1210 such that they do not overlap each other in the direction parallel to the first axis or parallel to the second axis.

[0653] In other embodiments, the first and second magnet units may be offset from each other in the first horizontal direction (or X-axis direction) or the second horizontal direction (or Y-axis direction). For example, in other embodiments, when viewed from above, the first magnet unit may be positioned to coincide with the first horizontal axis (or X-axis), and the second magnet unit may be positioned to coincide with the second horizontal axis (or Y-axis).

[0654] Each of the first magnet unit 1310A and the second magnet unit 1310B may be a bipolar magnet having one north pole and one south pole. For example, each of the first magnet unit 1310A and the second magnet unit 1310B may be a magnet divided or arranged as a north pole and a south pole 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).

[0655] For example, the first surface of the magnet 1310 facing the coil 1230 in the optical axis direction may be a south pole (or north pole). Also, the second surface of the magnet 1310 opposite to the first surface may be a north pole (or south pole).

[0656] In the embodiments shown in Figures 21a and 21b, the coil 1230 and the magnet 1310 face each other in the optical axis direction, but in other embodiments, the coil 1230 and the magnet 1310 may be arranged to face each other in a direction perpendicular to the optical axis direction (e.g., a second or third direction). In this case, the magnet units 1310A and 1310B are arranged on two adjacent sides of the housing 1210 from sides 1071A to 1071D, and the coil units 1230A and 1230B may be arranged on a movable part (e.g., holder 1140) to face the magnet units 1310A and 1310B in a direction perpendicular to the optical axis direction. In this case, the circuit board 1800 is connected to the first board 1801 and may include an additional board (or extension region) for which the coil units 1230A and 1230B are arranged. In another embodiment, the position sensor 1240 may be located on two sides of the housing 1210 together with the coil 1230, and may be located on or coupled to an additional board (or extension region) of the circuit board 1800 and electrically connected. In yet another embodiment, the magnet units 1310A and 1310B may be located on two adjacent corners of the housing 1210.

[0657] Referring to Figures 29a and 35a, the camera device 1200 may include a yoke 1380 positioned on the magnet 1310. The yoke 1380 can reduce or suppress the leakage flux of the magnet 1310, increase the electromagnetic force between the magnet 1310 and the coil 1230, and improve the driving force for OIS drive. The yoke 1380 may be made of a material that is attracted to magnetic materials. For example, the yoke 1380 may be made of a metallic material. Or, for example, the yoke 1380 may be made of a magnetic metallic material. Or, for example, the yoke 1380 may be a magnetic material, such as a magnet.

[0658] The yoke 1380 may be positioned in the housing 1210. For example, the yoke 1380 may be positioned between the housing 1210 and the magnet 1310. For example, the yoke 1380 may be positioned within the mounting portions 1141A and 1141B of the housing 1210. For example, the yoke 1380 may face the magnet 1310 or the coil 1230. For example, the yoke 1380 may be positioned on the second surface (e.g., the bottom surface) of the magnet 1310, opposite the first surface (e.g., the top surface) of the magnet 1310 facing the coil 1230. The yoke 1380 may be in contact with or attached to the magnet 1310. For example, the yoke 1380 may be attracted to the magnet 1310.

[0659] For example, the yoke 1380 may be coupled to the housing 1210 by an insert injection molding method. When the yoke 1380 and the housing 1210 are coupled by an insert injection molding method, at least a portion of the yoke 1380 is located inside the housing 1210, and at least another portion of the yoke 1380 is exposed from the housing 1210 and may be coupled to or attached to the magnet 1310.

[0660] In other embodiments, the yoke 1380 may be positioned within mounting portions 1141A and 141B of the housing 1210 by adhesive. The yoke 1380 may include a first yoke 1380A positioned on the first magnet unit 1310A and a second yoke 1380B positioned on the second magnet unit 1310B. For example, the first yoke 1380A may be positioned within the first mounting portion 1141A of the housing 1210, and the second yoke 1380B may be positioned within the second mounting portion 1141B of the housing 1210. Since the magnet 1310 can be attracted to the yoke 1380, the ease of assembly between the magnet 1310 and the housing 1210 can be improved, or the assembly between the magnet 1310 and the housing 1210 can be facilitated when assembling the magnet 1310 to the housing 1210.

[0661] In other embodiments, the first magnet unit 1310A and the second magnet unit 1310B may each be magnets divided or arranged as one north pole and one south pole in a direction perpendicular to the optical axis. In yet another embodiment, the first magnet unit 1310A and the second magnet unit 1310B may each be magnets containing two north poles and two south poles. An electromagnetic force may be generated between the first magnet unit 1310A and the second magnet unit 1310B and the first coil unit 1230A and the second coil unit 1230B, and the generated electromagnetic force allows the OIS moving part to tilt along the first axis or the second axis.

[0662] In other embodiments, the positions of the magnet 1310 and the coil 1230 in Figure 25 may be swapped. For example, the magnet 1310 may be located on the movable part 1100 (e.g., the sensor base 1270), and the coil 1230 may be located on the fixed part (e.g., the housing 1210). In this case, the yoke in Figure 35a may be located on the sensor base 1270. For example, the yoke may be located on the upper surface of the magnet 1310. Camera devices according to other embodiments may include a circuit board ("second circuit board") provided separately from the circuit board 1800 ("first circuit board") and located on the fixed part (e.g., the housing 1210). The coil 1230 may be located on or coupled to the second circuit board. The coil 1230 may be electrically or electrically connected to the second circuit board. For example, the second circuit board may be located below the housing 1210. A coil 1230 may be placed in the mounting portion 1141 of the housing 1210, in which case the mounting portion 1141 may be a through hole penetrating the lower part 1042 of the housing 1210. The position sensor 1240 may be placed on or coupled to the second circuit board. For example, the first sensor 1240A may be placed in the hollow of the first coil unit 1230A, and the second sensor 1240B may be placed in the hollow of the second coil unit 1230B. The position sensor 1240 may be electrically or electrically connected to the second circuit board.

The second control unit may be placed on the second circuit board. The second control unit may be electrically or electrically connected to the second circuit board. For example, the second control unit may be a driver IC. For example, the second control unit may be placed on, coupled to, or fixed to the first surface of the second circuit board.

The second coil 1230 may be arranged on the first surface of the second circuit board. The second control unit may be electrically or electrically connected to the coil 1230. A drive signal can be supplied to the coil 1230.For example, the second control unit can be electrically connected to coil units 1230A and 1230B, and can supply a first drive signal to the first coil unit 1230A and a second drive signal to the second coil unit 1230B. The second control unit can be electrically or electrically connected to the position sensor 1240. For example, the second control unit can supply power or a drive signal to the position sensor 1240. For example, the second control unit can supply power or a drive signal to the first sensor 1240A and the second sensor 1240B, respectively. The control unit 835 can receive the output signal of the position sensor 1240 and can control the drive signal (e.g., drive current) supplied to the coil 1230 using the output signal of the position sensor 1240. For example, the second control unit can receive the output signal of the first sensor 1240A and can control the first drive signal (e.g., first drive current) supplied to the first coil unit 1230A using the output signal of the first sensor 1240A. Furthermore, the second control unit can receive the output signal of the second sensor 1240B and control the second drive signal (e.g., second drive current) supplied to the second coil unit 1230B using the output signal of the second sensor 1240B. The second circuit board may include a terminal section. The terminal section may include a plurality of terminals. For example, a plurality of terminals on the second circuit board may be exposed from the side plate 1302 of the cover member 1300.
