Technical Field

[0001] The embodiments relate to a camera device and an optical instrument including the camera device. Background Technology

[0002] A camera device is a device that captures images or videos of a subject and is mounted in portable devices, drones, vehicles, etc. To improve image quality, camera devices may have image stabilization (IS) functions to correct or prevent image shake caused by user movement, such as optical image stabilization (OIS), autofocus (AF) functions, and / or zoom functions. Summary of the Invention

[0003] Technical issues

[0004] The embodiments provide a camera device and an optical instrument including the camera device, which can reduce power consumption, stably support the OIS moving unit, and prevent the holder or optical components from being damaged due to collisions with the drive board.

[0005] Technical solution

[0006] The camera device according to an embodiment includes a housing, a holder disposed in the housing, an optical component disposed on the holder, a support portion coupled to the holder, a drive plate disposed between the housing and the support portion and spaced apart from the holder, a first magnetic body disposed on the holder, and a second magnetic body disposed in the housing and facing the first magnetic body in a first direction.

[0007] The optical component can be positioned closer to the first magnetic body than the drive plate. The optical component can be positioned closer to the second magnetic body than the drive plate. A repulsive force can act between the first and second magnetic bodies along a first direction. At least a portion of the support can pass through the housing to be coupled to the retainer. The drive plate can be positioned in a direction perpendicular to the first direction without overlapping with the retainer.

[0008] The support may include a main body and an extension extending from the main body to engage with a retainer, and at least a portion of the drive plate may contact the main body. At least a portion of the drive plate may overlap the support in a second direction. The second direction may be perpendicular to the first direction and may be the incident direction of light entering the optical component.

[0009] The housing may include a first side facing the exit surface of the optical component and a second side arranged opposite to the first side in a first direction, a support portion passing through the second side of the housing to be coupled to the retainer, and a drive plate being disposed between the second side of the housing and the support portion.

[0010] The drive plate may include a first protrusion protruding toward a second side of the housing and a second protrusion protruding toward a support portion. The housing may include a first recess disposed on the second side, at least a portion of the first protrusion being disposed in the first recess. The support portion may include a second recess, at least a portion of the second protrusion being disposed in the second recess.

[0011] The second magnetic body can be disposed on the second side of the housing, and the first magnetic body can be disposed on the side of the retainer facing the second side of the housing.

[0012] At least a portion of the drive plate may be disposed on the outside of the housing. The second magnetic body may be located between the first magnetic body and the drive plate. The housing may include a first portion disposed between the second magnetic body and the drive plate. The drive plate may include a first protrusion protruding toward the first portion of the housing and a second protrusion protruding toward a support portion, at least a portion of the first protrusion may be disposed on the first portion, and at least a portion of the second protrusion may be disposed on the support portion.

[0013] The distance between the optical component and the driving plate can be greater than the distance between the optical component and the first magnetic body. The driving plate can be non-overlapping with the optical component in a direction perpendicular to the first direction. The optical component can be a prism or a mirror.

[0014] According to another embodiment, the camera device includes a housing, a holder disposed within the housing, an optical component disposed on the holder, a first magnetic body disposed on a first side of the holder, a second magnetic body disposed on a first side of the housing facing the first side of the holder, a support portion passing through the first side of the housing to engage with the first side of the holder, and a drive plate disposed between the first side of the housing and the support portion. The first and second magnetic bodies can be configured to generate a repulsive force acting between the first and second magnetic bodies.

[0015] The first magnetic body may be located inside the housing, and at least a portion of the drive plate may be located outside the housing.

[0016] Beneficial effects

[0017] According to an embodiment, the drive plate can be disposed on the outside of the housing, so that the drive plate, which serves as the rotation axis, can be disposed away from the retainer, which serves as the OIS moving unit.

[0018] According to the embodiment, since the driver board is located far from the OIS moving unit, the moving distance of the OIS moving unit required for hand shake compensation can be reduced, and the power consumption required to move the OIS moving unit can be reduced.

[0019] Furthermore, according to embodiments, the drive board can be designed to have a larger size, and the OIS moving unit can be stably supported and guided.

[0020] Furthermore, according to the embodiment, the drive plate does not directly contact the retainer, and the drive plate and the retainer do not directly collide with each other upon impact. Therefore, according to the embodiment, damage to the retainer and optical components caused by collision with the drive plate can be suppressed or prevented. Attached Figure Description

[0057] In the following description, embodiments of the present disclosure that can specifically implement the above aspects will be described with reference to the accompanying drawings.

[0058] In the following description of the embodiments, it will be understood that when each component is referred to as being "on" or "below" another component, it may be directly above or below the other component, or it may be indirectly configured such that one or more intermediate components are also present. Furthermore, when a component is referred to as being "on" or "below," the term "on" may include both "below" and "on" the component.

[0059] Furthermore, the relational terms “first,” “second,” “upper,” “lower,” and “below” are used herein only to distinguish one subject or component from another, and do not necessarily require or imply any physical or logical relationship or order between such subjects or components. Where possible, the same reference numerals will be used in all figures to refer to the same parts.

[0060] Furthermore, the terms “comprising,” “including,” and “having” described herein should be interpreted as not excluding other components, but further including such other components, as the corresponding components may be inherent unless otherwise stated. Additionally, the term “corresponding to” described herein may cover at least one of the meanings of “facing” and “overlapping.”

[0061] In the following description, a camera device according to an embodiment and an optical instrument including the camera device will be described with reference to the accompanying drawings. For ease of description, a Cartesian coordinate system (x, y, z) will be used to describe the camera device according to the embodiment; however, the embodiment is not limited to this, and other coordinate systems may be used. In each drawing, the X-axis and Y-axis may refer to directions perpendicular to the Z-axis, where the Z-axis is the optical axis (OA) direction. Furthermore, the Z-axis direction, which is the optical axis (OA) direction, may be referred to as a "first direction," the X-axis direction may be referred to as a "second direction," and the Y-axis direction may be referred to as a "third direction." Additionally, the Y-axis may be referred to as a "first axis," and the Y-axis direction may be referred to as a "first axis direction." The X-axis may be referred to as a "second axis," and the X-axis direction may be referred to as a "second axis direction." For example, the optical axis direction may be the direction of the optical axis or a direction parallel to the optical axis.

[0062] Additionally, in the following text, "terminal" may be referred to as a pad, electrode, or conductive layer. Furthermore, in the following text, "code value" may be referred to as data or digital value.

[0063] Additionally, in an embodiment, when two components are joined together by a connection between a protrusion and a hole, one of the components may be a joining protrusion (or a joining hole), and the remaining component may be a corresponding joining hole (or joining protrusion).

[0064] The camera device according to the embodiment can perform image stabilization, autofocus, and zoom functions. The "image stabilization" function can be a function that moves the lens in a direction perpendicular to the optical axis or tilts the lens relative to the optical axis to eliminate vibration (or movement) caused by the user's hand tremors. The "autofocus" function can be a function that automatically focuses on the object by moving the lens in the optical axis direction according to the distance to the object, thereby enabling the image sensor to obtain a clear image of the object. The "zoom" function can be a function that simultaneously increases or decreases the magnification of a distant object using a zoom lens while capturing the object.

[0065] In the following text, "camera device" may be referred to as "camera", "camera module", "image capture device" or "photographic device".

[0066] Figure 1 This is a perspective view of the camera device 200 according to an embodiment. Figure 2 yes Figure 1 An exploded perspective view of the camera device 200 shown, and Figure 3 It is along Figure 1 The sectional view of the camera device is taken by line AB.

[0067] Reference Figures 1 to 3The camera device 200 may include a first actuator 310, a second actuator 320, and an image sensing unit 330.

[0068] The second actuator 320 may include a stationary unit and an OIS moving unit. The OIS moving unit 100 may alternatively be referred to as a "moving unit," "rocking unit," or "motion unit."

[0069] The fixing unit can be a fixed element. That is, the fixing unit can remain stationary in the optical axis direction (e.g., the Z-axis direction). Additionally, the fixing unit can remain stationary in the direction intersecting the optical axis (e.g., the X-axis or Y-axis direction). Furthermore, the fixing unit can remain stationary relative to an axis intersecting the optical axis (e.g., the X-axis or Y-axis). Additionally, components attached to the fixing unit can correspond to the fixing unit. For example, the fixing unit can include a first housing 50. Furthermore, the fixing unit can include components attached to the first housing 50 (e.g., plate unit 250). Additionally, the fixing unit can include components attached to the plate unit 250, such as an OIS coil 230, a position sensing unit 240, a magnet 63, a gyroscope sensor 82, or a second driver 260.

[0070] The OIS moving unit can tilt or rotate relative to the fixed unit within a predetermined angle range, using at least one axis intersecting the optical axis as a reference. The OIS moving unit can move left or right relative to the fixed unit, using a first axis intersecting the optical axis as a reference. Furthermore, the OIS moving unit can move left or right relative to the fixed unit, using a second axis intersecting the optical axis as a reference. For example, the first axis can be perpendicular to the optical axis direction, and the second axis can intersect both the optical axis direction and the first axis. For example, the first axis can be the X-axis (or Y-axis), and the second axis can be the Y-axis (or X-axis). In another embodiment, each of the first and second axes can intersect either the X-axis or the Y-axis. For example, the first and second axes can be perpendicular to each other.

[0071] The OIS moving unit may include an optical component 40. The OIS moving unit may include a retainer 30. For example, the OIS moving unit may include a component coupled to or connected to the retainer 30. For example, the OIS moving unit may include at least one of magnets 31 and 32, magnetic body 31, or yoke 33. The OIS moving unit may also include a support joint 60.

[0072] The second actuator 320 can move the optical component 40 to perform optical image stabilization (OIS) operation to achieve hand shake compensation, and is alternatively referred to as the "second drive unit", "OIS drive unit" or "hand shake compensation drive unit".

[0073] The second actuator 320 can alter the path of light. For example, the second actuator 320 may include an optical component 40 configured to alter the light path. The second actuator 320 may alternatively be referred to as a "light path changer".

[0074] The first actuator 310 can move the lens assemblies 312 and 313 in the optical axis direction to perform autofocus and / or zoom functions, and may alternatively be referred to as the "first drive unit" or "AF and zoom drive unit". The first actuator 310 may be referred to as the "second actuator", and the second actuator 320 may be referred to as the "first actuator".

[0075] For example, the first actuator 310 may be disposed on the rear end of the second actuator 320 and may be coupled to the second actuator 320. For example, the first actuator 310 may be disposed between the image sensor 540 and the second actuator 320.

[0076] The image sensing unit 330 can receive and detect light that has passed through the optical component 40 of the second actuator 320 and the lens assemblies 311, 312, and 313 of the first actuator 310, and can convert the detected light into an electrical signal.

[0077] The camera device 200 may further include a cover member 300. The cover member 300 may be formed in the shape of a box including an open lower part, an upper plate 301, and a side plate 302. The cover member 300 of the camera device 200 may accommodate a first actuator 310, a second actuator 320, and an image sensing unit 330.

[0078] The upper plate 301 of the cover member 300 may include an opening 303 or hole formed therein to expose the incident surface of the optical member 40.

[0079] In addition, the camera device 200 may further include a bracket (not shown) to accommodate the first actuator 310, the second actuator 320 and the image sensing unit 330.

[0080] The cover member 300 can be formed as a metal plate, but is not limited to this, and can be formed of plastic or resin. In addition, the cover member 300 can be made of a material that blocks electromagnetic waves.

[0081] The camera device 200 may further include a protective film (not shown) disposed on the upper plate 301 of the cover member 300 to cover the opening 303 in the cover member 300. The protective film may be formed of a light-transmitting material and may prevent foreign objects from entering the camera device 200 and may protect the optical components 40 from impact.

Figure 11 This is a view used to illustrate the electromagnetic forces and motion of the OIS moving unit based on the interaction between OIS magnets 31A, 31B, and 32 and coil units 230A to 230C. Figure 12 This is a cross-sectional view of the second actuator 320 taken along line CD in Figure 4, and Figure 13 This is a cross-sectional view of the second actuator 320 taken along line EF in Figure 4.

[0083] Refer to Figure 4 to Figure 13 The second actuator 320 may include an optical component 40 and a second drive unit 70, the second drive unit 70 being configured to rotate the optical component 40 by a predetermined angle in a direction intersecting the optical axis direction (e.g., the Z-axis direction) (e.g., the X-axis direction or the Y-axis direction).

[0084] The optical component 40 can be used to change the path of light. For example, the optical component 40 can receive light that has passed through the opening 303 in the cover component 300 and can emit the received light toward the first actuator 310.

[0085] The optical component 40 may include a reflective element capable of changing the direction of light travel. For example, the optical component 40 may be a prism that reflects light. However, this disclosure is not limited thereto. In another embodiment, the optical component 40 may be a mirror or a reflective element.

[0086] Optical component 40 can be disposed in holder 30. Optical component 40 can change the optical path of incident light to an optical axis parallel to the central axis Z of lens unit, so as to convert incident light into parallel light, and the parallel light can reach image sensor 540 via first lens assembly 640, second lens assembly 622 and third lens assembly 624.

[0087] Reference Figure 5 For example, optical component 40 may include an incident surface 8A and an exit surface 8B, and may reflect light incident on the incident surface 8A and emit light through the exit surface 8B. For example, optical component 40 may be a right-angle prism including an incident surface 8A, a reflecting surface 8C, and an exit surface 8B. For example, the interior angle between the incident surface 8A and the exit surface 8B may be a right angle.

[0088] Additionally, for example, each of the first interior angle between the incident surface 8A and the reflecting surface 8C, and the second interior angle between the exiting surface 8B and the reflecting surface 8C, can be between 30 degrees and 60 degrees. For example, each of the first and second interior angles can be 45 degrees. However, this disclosure is not limited thereto. Furthermore, due to the change in the optical path based on the optical component 40, the thickness of the camera device 200 in the direction perpendicular to the incident surface 8A of the optical component 40 can be reduced, and therefore, the thickness of the mobile device or terminal 200A in which the camera device 200 is mounted can be reduced.

[0089] For example, the second actuator 320 may include a first housing 50, a retainer 30 disposed in the first housing 50, an optical component 40 disposed in the retainer 30, and a support joint 60 disposed between the retainer 30 and the housing 50. Additionally, the second actuator 320 may include a second drive unit 70.

[0090] Reference Figure 5 and Figures 6a to 6cThe retainer 30 may include a mounting portion 104, on which the optical component 40 is disposed or mounted. The mounting portion 104 may have a recessed shape and may include a mounting surface 104a (or a mounting surface) on which the reflective surface 8C of the optical component 40 is disposed. For example, the mounting surface 104a may be an inclined surface that is tilted relative to the optical axis direction.

[0091] For example, an adhesive for attaching the optical component 40 may be provided on the mounting surface 104a of the retainer 30, and at least one recess 104b for receiving the adhesive may be formed in the mounting surface 104a.

[0092] The retainer 30 may include a first side portion 31a to a fourth side portion 31d (or a first side surface to a fourth side surface). The first side portion 31a and the second side portion 31b may face each other or be disposed opposite each other in a first direction. The third side portion 31c and the fourth side portion 31d may be located between the first side portion 31a and the second side portion 31b, and may face each other or be disposed opposite each other.

[0093] For example, the retainer 30 may include a first opening exposing the incident surface 8A of the optical member 40 and a second opening exposing the exit surface 8B of the optical member 40. For example, the first opening may be formed on the upper side of the retainer 30, and the second opening may be formed in a side surface 31a (front outer surface) of the retainer 30 facing the lens assembly (e.g., 311) of the first actuator 310. The exit surface 8B of the optical member 40 mounted in the retainer 30 may be configured to face the lens assembly (e.g., 311) of the first actuator 310.

[0094] Reference Figure 6a and Figure 6b The upper surface 18 of the retainer 30 may include a first surface 18A and a second surface 18B having a height difference from the first surface 18A in a second direction (e.g., the X-axis direction). The first surface 18A may be configured to be adjacent to or in contact with the rear outer surface 31b of the retainer 30, and the second surface 18B may be configured to be adjacent to or in contact with the first side portion 31a of the retainer 30. The second surface 18B may be located below the first surface 18A. For example, the second surface 18B may be configured to be closer to the lower surface 19 of the retainer 30 than the first surface 18A.

[0095] Because the second surface 18B has a height difference with the first surface 18A, spatial interference between the retainer 30 and the first housing 50 can be prevented when the retainer 30 is tilted in the second direction (e.g., the X-axis direction) or rotated by a predetermined angle.

[0096] For example, at least one stop 38 may be formed on the upper surface of the retainer 30 (e.g., the second surface 18B). The stop 38 may be a protrusion or projection that projects upward from the upper surface of the retainer 30 (e.g., the second surface 18B). For example, the stop 38 may be formed on the upper surface of each of the first and second sides of the retainer 30. The tilting or rotation of the retainer 30 in the second direction may be limited by the stop 38. For example, the height of the upper surface of the stop 38 may be less than or equal to the height of the first surface 18A.

[0097] The retainer 30 may include sides (or outer surfaces) 31c and 31d that are disposed facing each other or opposite each other. For example, the placement portion 104 may be located between the two sides 31c and 31d of the retainer 30. For example, the two sides 31c and 31d may be configured to be opposite each other or to face each other in a third direction (e.g., the Y-axis direction).

[0098] Each of the third side portion 31c and the fourth side portion 31d of the retainer 30 may include a first outer surface 19A and a second outer surface 19B having a height difference from the first outer surface 19A in a third direction (e.g., the Y-axis direction). The first outer surface 19A may be configured to be adjacent to or in contact with the second side portion 31b of the retainer 30, and the second outer surface 19B may be configured to be adjacent to or in contact with the first side portion 31a of the retainer 30. The inner surface of the retainer 30 may be configured to be closer to the first outer surface 19A of the retainer 30 than the second outer surface 19B of the retainer 30.

[0099] Since the second outer surface 19B of the retainer 30 has a height difference with the first outer surface 19A, spatial interference between the retainer 30 and the first housing 50 can be prevented when the retainer 30 is tilted in a third direction (e.g., the Y-axis direction) or rotated by a predetermined angle.

[0100] For example, at least one stop 39A may be formed on the third and fourth sides (e.g., the second outer surface 19B) of the retainer 30. The stop 39A may be a protrusion or projection extending from the outer surface (e.g., the second outer surface 19B) of each of the third and fourth sides 31c and 31d of the retainer 30. The tilting or rotation of the retainer 30 in the third direction may be limited by the stop 39A. For example, the protrusion height of the stop 39A from the second outer surface 19B may be less than or equal to the height difference between the first and second outer surfaces 19A.

[0101] Reference Figure 6cThe lower surface 17 of the retainer 30 may include a first surface 17A and a second surface 17B having a height difference from the first surface 17A in a second direction (e.g., the X-axis direction). The first surface 17A may be configured to be adjacent to or in contact with a first side 31a of the retainer 30, and the second surface 17B may be configured to be adjacent to or in contact with a second side 31b of the retainer 30. The first surface 17A may be located below the second surface 17B. For example, the upper surface 18 of the retainer 30 may be closer to the second surface 17B than the first surface 17A.

[0102] Since the second surface 17B of the lower surface 17 of the retainer 30 has a height difference with the first surface 17A, spatial interference between the retainer 30 and the second OIS coil 230C can be prevented when the retainer 30 is tilted in the second direction (e.g., the X-axis direction) or rotated by a predetermined angle.

[0103] For example, at least one stop 41 may be formed on the lower surface of the retainer 30 (e.g., the second surface 17B). The stop 41 may be a protrusion or projection that projects downward from the lower surface of the retainer 30 (e.g., the first surface 17A). The tilting or rotation of the retainer 30 in a second direction may be limited by the stop 41. For example, the protruding length of the stop 38 projecting from the second surface 17B may be less than or equal to the height difference between the first surface 17A and the second surface 17B of the lower surface 17 of the retainer 30. In another embodiment, the stop may be located on the second surface 17B of the lower surface of the retainer 30.

[0104] The retainer 30 may include: a first mounting recess 16A (see Figure 5 A first mounting recess 16A is formed in the holder 30 to allow the first OIS magnet 31 (or "first magnet unit") to be disposed or placed therein; and a second mounting recess 16B (see Figure 6c A second mounting recess 16B is formed in the retainer 30 so that a second OIS magnet 32 ​​(or "second magnet unit") can be disposed or mounted therein.

[0105] For example, the first placement recess 16A may be formed in the outer surface (e.g., the first outer surface 19A) of each of the third side portion 31c and the fourth side portion 31d of the retainer 30. For example, the first placement recess 16A may be formed in the shape of a recess in the first outer surface 19A of each of the third side portion 31c and the fourth side portion 31d of the retainer 30.

[0106] For example, the second placement recess 16B may be formed in the lower surface 17 (e.g., the first surface 17A) of the retainer 30. For example, the second placement recess 16B may be formed in the shape of a recess in the lower surface 17 (e.g., the first surface 17A) of the retainer 30.

[0107] Reference Figure 6b The second side 31b of the retainer 30 may include a first surface 21a, a second surface 21b adjacent to or in contact with the third side 31c, and a third surface 21c adjacent to or in contact with the fourth side 31d.

[0108] When viewed from the rear, the first surface 21a can be located in the center, the second surface 21b can be located to the left of the first surface 21a, and the third surface 21c can be located to the right of the first surface 21a.

[0109] Each of the second surface 21b and the third surface 21c may have a height difference from the first surface 21a in a first direction (e.g., the Z-axis direction). For example, the inner surface of the retainer 30 may be configured to be closer to the first surface 21a than each of the second surface 21b and the third surface 21c. For example, the second surface 21b and the third surface 21c may be located in the same plane. Alternatively, for example, the height difference between the first surface 21a and the second surface 21b may be the same as the height difference between the first surface 21a and the third surface 21c. However, this disclosure is not limited thereto. In another embodiment, the two height differences may be different from each other.

[0110] For example, a recess 106 may be formed in the second side portion 31b of the retainer 30, and the drive plate 61 may be disposed or accommodated in the recess 106. For example, the recess 106 may be provided in the center of the second side portion 31b, and may be formed to be recessed in the outer surface of the second side portion 31b.

[0111] The retainer 30 may include engaging recesses 105A and 105B, which are formed in the retainer 30 to engage with the support 64. For example, engaging recesses 105A and 105B may be formed in the outer surface of the second side portion 31b of the retainer 30.

[0112] For example, the retainer 30 may include a first engagement recess 105A formed in a second surface 21b on the outer surface of the second side portion 31b and a second engagement recess 105B formed in a third surface 21c.

[0113] For example, at least one recess 2A may be formed in at least one of the side surface and bottom surface of each of the first engaging recess 105A and the second engaging recess 105B. For example, at least one recess 2A in the retainer 30 may correspond to at least one protrusion 7A of the support 64, or may be formed at a position corresponding to at least one protrusion 7A. At least one recess 2A in the retainer 30 may be engaged with at least one protrusion 7A of the support 64.

[0114] The retainer 30 may include at least one stop (not shown) formed on the outer surface 31b of the second side portion 31b. For example, the stop may be formed as a protrusion or projection protruding from each of the second surface 21b and the third surface 21c of the second side portion 31b.

[0115] The retainer 30 may include a placement portion 37 (or a receiving portion) in which the magnetic body 62 is disposed or received. The placement portion 37 may be a recess or a groove.

[0116] For example, the mounting portion 37 may be provided on the second side of the retainer 30. For example, the mounting portion 37 may be provided on the second side 31b of the retainer 30. For example, the mounting portion 37 may be formed in the first surface 21a of the retainer 30.

[0117] The first housing 50 may be disposed within the cover member 300. For example, an adhesive or shielding member may be disposed between the first housing 50 and the cover member 300, and the first housing 50 may be coupled or fixed to the cover member 300.

[0118] The retainer 30 may be disposed within the first housing 50. The first housing 50 may accommodate the retainer 30 and may expose the incident surface 8A and the exit surface 8B of the optical component 40 disposed within the retainer 30.

[0119] Reference Figures 9a to 9d For example, the first housing 50 may include a first opening 53A (or a first hole) formed in the first housing 50 to expose the incident surface 8A of the optical component 40. Additionally, the first housing 50 may include a second opening 53B (or a second hole) formed in the first housing 50 to expose the exit surface 8B of the optical component 40.

[0120] The first housing 50 may include an upper portion 27A, a lower portion 27B, and a side portion disposed between the upper portion 27A and the lower portion 27B. For example, the side portion of the first housing 50 may include a plurality of side portions 28A to 28D. The upper portion 27A and the lower portion 27B of the first housing 50 may face each other or be disposed opposite each other in a second direction (e.g., the X-axis direction).

[0121] For example, the first housing 50 may include a first side 28A, a second side 28B, a third side 28C, and a fourth side 28D.

[0122] For example, the first side portion 28A of the first housing 50 may be configured to face or be opposite to the lens assembly (e.g., 311) of the first actuator 310. The first side portion 28A may face the exit surface 8B of the optical member 40. A first opening 53A may be formed in the upper portion 27A, and a second opening 53B may be formed in the first side portion 28A.

[0123] The second side portion 28B can be disposed facing or opposite to the first side portion 28A in a first direction. The third side portion 28C and the fourth side portion 28D can be disposed between the first side portion 28A and the second side portion 28D, and can be disposed facing or opposite to each other in a third direction. For example, the third side portion 28C can connect one end of the first side portion 28A to one end of the second side portion 28B, and the fourth side portion 28D can connect the other end of the first side portion 28A to the other end of the second side portion 28B.

[0124] For example, the first housing 50 may include: a first hole 54A formed in a third side portion 28C of the first housing 50 to allow a first OIS coil unit 230A to be disposed or arranged therein; a second hole 54B formed in a fourth side portion of the first housing 50 to allow a second OIS coil unit 230B to be disposed or arranged therein; and a third hole 54C formed in a lower portion 27B of the first housing 50 to allow a third OIS coil unit 230C to be disposed or arranged therein. For example, each of the first hole 54A to the third hole 54C may have a through-hole shape. However, this disclosure is not limited thereto. In another embodiment, each of the first hole to the third hole may have a recessed shape.

[0125] Additionally, a recess 56 (or through hole) for which the second actuator 260 is disposed or placed may be formed in the fourth side portion 28D (or the third side portion 28C) of the first housing 50. For example, the recess 56 may be formed to be spaced apart from the second hole 54B.

[0126] The first housing 50 may include at least one engagement protrusion 51 formed on at least one of the third side portion 28C and the fourth side portion 28D. For example, the engagement protrusion 51 may protrude from the outer surface of at least one of the third side portion 28C and the fourth side portion 28D. Additionally, the first housing 50 may include at least one engagement protrusion 52A formed on the first side portion 28A. For example, the engagement protrusion 52A may protrude from the outer surface of the first side portion 28A.

[0127] Additionally, the first housing 50 may include at least one engagement protrusion 52B formed on the lower portion 28B. For example, the engagement protrusion 52B may be formed to protrude from the outer surface of the lower portion 28B.

[0128] A guide protrusion 59A for guiding the first circuit board 250A may be formed on at least one of the upper and lower ends of the third side portion 28C of the first housing 50. Additionally, a guide protrusion 59B for guiding the second circuit board 250B may be formed on at least one of the upper and lower ends of the fourth side portion 28D of the first housing 50.

[0129] Reference Figure 9d The first housing 50 may include a recess 58 corresponding to the front protrusion 61C of the drive plate 61.

[0130] For example, the first housing 50 may include at least two recesses 58A and 58B formed in its second side portion 28B corresponding to at least two front protrusions 61C1 and 61C2 of the drive plate 61. For example, the at least two recesses 58A and 58B in the first housing 50 may be arranged to be spaced apart from each other in a second direction (X-axis direction). In another embodiment, the at least two recesses in the first housing 50 may be arranged to be spaced apart from each other in a third direction (Y-axis direction).

[0131] For example, the first recess 58A may include a bottom surface 1W and a plurality of side surfaces 1A to 1D. The area of ​​at least one of the plurality of side surfaces 1A to 1D of the first recess 58A may be different from the area of ​​at least another side surface of the plurality of side surfaces 1A to 1D of the first recess 58A.

[0132] For example, the two side surfaces 1C and 1D of the first recess 58A facing each other in the second direction can have symmetrical shapes and the same area. Additionally, the two side surfaces 1A and 1B of the first recess 58A facing each other in the third direction can have symmetrical shapes and the same area.

[0133] The first area of ​​each of the side surfaces 1C and 1D of the first recess 58A facing each other in the second direction may be different from the second area of ​​each of the side surfaces 1A and 1D of the first recess 58A facing each other in the third direction. For example, the first area may be smaller than the second area. In another embodiment, the first area may be larger than the second area. For example, the bottom surface of the first recess 58A may have a rectangular shape or an elliptical shape. However, this disclosure is not limited thereto.

[0134] The second recess 58B may include a bottom surface and a plurality of side surfaces. The plurality of side surfaces of the second recess 58B may have the same shape. For example, the plurality of side surfaces of the second recess 36B may have the same area. The plurality of side surfaces of the second recess 36B may be symmetrical to each other in a second direction and a third direction. For example, the bottom surface of the second recess 36B may have a square shape or a circular shape. However, this disclosure is not limited thereto.

[0135] Reference Figure 9d Each of the first recess 58A and the second recess 58B has four side surfaces. In another embodiment, the number of side surfaces may be three or five or more.

[0136] Manufacturing tolerances may occur in the first and second recesses in the first housing 50 and / or the front protrusion of the drive plate 61. If both the first and second recesses in the housing 50 have... Figure 9d The shape of the second recess 58B shown means that, due to manufacturing tolerances, the front protrusions 61C1 and 61C2 of the drive plate 61 may not be able to properly or stably engage with the first and second recesses in the first housing 50.

[0137] In this embodiment, since the first recess 58A in the first housing 50 is formed with a different shape than the second recess 58B, sufficient engagement margin can be ensured between the front protrusions 61C1 and 61C2 of the drive plate 61 and the first recess 58A and the second recess 58B in the first housing 50. That is, even with the aforementioned manufacturing tolerances, the front protrusions 61C1 and 61C2 of the drive plate 61 can be correctly or stably engaged with the first recess 58A and the second recess 58B in the first housing 50 due to the first recess 58A, and therefore, OIS operation can be performed stably.

[0138] However, in another embodiment, the first recess and the second recess in the first housing 50 may have the same shape. For example, in another embodiment, each of the first recess and the second recess in the first housing 50 may have Figure 9d The shape of the first recess 58A or the second recess 58B shown.

[0139] The first housing 50 may include protrusions or steps (not shown) formed around at least two recesses 58A and 58B. Lubricant may be disposed between the front protrusions 61C1 and 61C2 and the recesses 58A and 58B in the first housing 50 to reduce friction. The protrusions (or steps) of the first housing 50 formed around the first recesses 58A and 58B can prevent lubricant leakage.

[0140] For example, the first housing 50 may include a protrusion 57 projecting from the inner surface of the second side 28B toward the first side 28A. In another embodiment, the protrusion 57 may be omitted.

[0141] The first housing 50 may include a portion (or a first portion) or region (or a first region) disposed between the magnetic body 63 and the drive plate 61. For example, the first portion of the first housing 50 disposed between the magnetic body 63 and the drive plate 61 may be a part (or region) of the second side 28B of the first housing 50. For example, a protrusion 57 may be disposed or formed on the first portion of the first housing 50. At least a portion of the front protrusion 61C of the drive plate 61 may be disposed on the first portion of the first housing 50, and the rear protrusion 61B of the drive plate 61 may be disposed on the support portion. For example, the front protrusion 61C of the drive plate 61 may protrude toward the first portion of the first housing 50, at least a portion of the front protrusion 61C may contact the first portion of the first housing 50, and the rear protrusion 61B of the drive plate 61 may contact the support portion.

[0142] The first housing 50 may include a receiving portion 44A in which the magnetic body 63 is received or disposed. The receiving portion 44A may be in the form of a recess or a hole. For example, the receiving portion 44A may be formed in a first part of the first housing 50.

[0143] The receiving portion 44A may be provided on the second side portion 28B of the first housing 50. The receiving portion 44A may be provided on the inner surface of the second side portion 28B of the first housing 50. For example, the receiving portion 44A may be provided on or formed on the protrusion 57 of the first housing 50. For example, the receiving portion 44A may be provided on or formed on the inner surface or front surface of the protrusion 57 of the first housing 50. For example, the receiving portion 44A may be provided opposite to the recesses 58A and 58B.

[0144] Reference Figure 9d When the first housing 50 is viewed from the rear, the first recess 58A is located on the upper side, and the second recess 58B is located on the lower side. However, this disclosure is not limited thereto. In another embodiment, the second recess 58B may be located on the upper side of the first recess 58A.

[0145] The first housing 50 may include a mounting portion 79, in which at least a portion of the drive plate 61 is disposed. The mounting portion 79 may be located on a second side portion 28B of the first housing 50. The mounting portion 79 may be a recess in the outer surface of the second side portion 28B of the first housing 50. For example, the mounting portion 29 may include a bottom surface 79A and a side surface (or sidewall) 79B, wherein the bottom surface 79A has a height difference with the outer surface of the second side portion 28B of the first housing 50 in a first direction, and the side surface (or sidewall) 79B is located between the bottom surface 79A and the outer surface of the second side portion 28B of the first housing 50.

[0146] For example, recesses 58A and 58B may be provided on or formed in the bottom surface 79A of the mounting portion 79. The mounting portion 79 can be used to prevent the drive plate 61 from separating from the first housing 50 and to enable the drive plate 61 to stably support the retainer 30. In addition, since the drive plate 61 is disposed in the mounting portion 79, the size of the camera device 200 in the first direction (optical axis direction) can be reduced. In another embodiment, the first housing 50 may not include the mounting portion 79.

[0147] The first housing 50 may include an opening 55 through which at least a portion of the support 64 passes. For example, the opening 55 may be formed in a second side portion 28B of the first housing 50. For example, the opening 55 may be a through-hole extending through the second side portion 28B. For example, at least one through-hole may be formed in the second side portion 28B of the first housing 50. For example, the opening 55 may include a first through-hole 55A and a second through-hole 55B formed in the second side portion 28B of the first housing 50.

[0148] like Figure 9c As shown, when viewed from the rear side of the first housing 50, the first through hole 55A may be located on one side of the protrusion 57 of the first housing 50 (e.g., the right side), and the second through hole 55B may be located on the other side of the protrusion 57 (e.g., the left side). A portion of the support portion 64 may pass through the first through hole 55A in the first housing 50, and another portion of the support portion 64 may pass through the second through hole 55B in the first housing 50.

[0149] Next, the support joint 60 will be described.

[0150] The support joint 60 can support the OIS moving unit relative to the first housing 50. The support joint 60 can be disposed between the OIS moving unit and the first housing 50. The support joint 60 may include a drive plate 61 disposed between the first housing 50 and the support part 64.

[0151] The drive plate 61 may also be referred to as "mover", "drive plate", "plate", "rotating plate", "moving plate", "support plate", "tilting guide" or "tilting plate".

[0152] The drive plate 61 may include a first axis for tilting the OIS moving unit. Additionally, the drive plate 61 may include a second axis for tilting the OIS moving unit. The drive plate 61 may support the OIS moving unit relative to the fixed unit. The drive plate 61 may guide the tilting or movement of the OIS moving unit.

[0153] The support joint 60 may include a support portion 64 that is coupled to the retainer 30 and supports the drive plate 61. At least a portion of the support portion 64 may pass through at least a portion of the first housing 50 to be coupled to the retainer 30. At least a portion of the support portion 64 may pass through a second side portion 28B of the first housing 50 to be coupled to the retainer 30.

[0154] The drive plate 61 may be disposed between the first housing 50 and the support portion 64. At least a portion of the drive plate 61 may contact or be in close contact with the first housing 50, and at least another portion of the drive plate 61 may contact or be in close contact with the support portion 64.

[0155] The support part 64 may also be referred to as "joint part", "retainer rigid body", "mover rigid body" or "retainer rigid body".

[0156] For example, the support portion 64 can be formed from injection-molded material, plastic, or resin. Alternatively, in another embodiment, the support portion 64 can be formed from metal or as a metal plate. Alternatively, the support portion 64 can be formed as a heat dissipation member. The support portion 64 can have a polyhedral shape.

[0157] Reference Figure 7 , Figure 8a , Figure 8b and Figure 10a The support portion 64 may include a recess 36 corresponding to a rear protrusion 61B of the drive plate 61. For example, the support portion 64 may include at least two recesses 36A and 36B corresponding to at least two rear protrusions 61B1 and 61B2 of the drive plate 61. For example, at least two recesses 36A and 36B in the support portion 64 may be arranged to be spaced apart from each other in a third direction (Y-axis direction). In another embodiment, at least two recesses in the support portion 64 may be arranged to be spaced apart from each other in a second direction (X-axis direction).

[0158] The first recess 36A in the support portion 64 may include a bottom surface 1M and a plurality of side surfaces 1E to 1H. Additionally, the second recess 36B may include a bottom surface and a plurality of side surfaces.

[0159] The description of the first recess 58A and the second recess 58B in the first housing 50 can be directly or similarly applied to the first recesses 36A and 36B in the support portion. Protrusions (or steps) may be formed around the recesses 36A and 36B in the support portion 64. Lubricant may be provided between the rear protrusions 61B1 and 61B2 and the recesses 36A and 36B in the support portion 64 to reduce friction. The protrusions (or steps) of the support portion 64 formed around the first recesses 36A and 36B can prevent lubricant overflow.

[0160] A portion of the support 64 may pass through the first housing 50 to be coupled to the retainer 30. For example, a portion of the support 64 may pass through the first housing 50 to be coupled to a second side of the retainer 30.

[0161] The support portion 64 may include a body 93 and at least one extension 94a or 94b (or protrusion) extending from the body 93. For example, at least one extension 94a or 94b may pass through an opening 55 in the first housing 50 to engage with the retainer 30.

[0162] For example, the support portion 64 may include: a body 93 facing the drive plate 61; a first extension 94a extending from one side of the body 93 and passing through a first through hole 55A in the first housing 50 to be coupled to the retainer 30; and a second extension 94b extending from the other side of the body 93 and passing through a second through hole 55B in the first housing 50 to be coupled to the retainer 30.

[0163] For example, the first extension 94a may engage with the first engagement recess 105A in the retainer 30, and the second extension 94b may engage with the second engagement recess 105B in the retainer 30. For example, the extensions 94a and 94b of the support 64 may be bonded to the engagement recesses 105A and 105B in the retainer 30 using an adhesive. For example, the first extension 94a and the second extension 94b may be bilaterally symmetrical with respect to the body 93. In another embodiment, the first extension 94a and the second extension 94b may be asymmetrical with respect to the body 93.

[0164] Each of the extensions 94a and 94b may include at least one protrusion 7A to engage with at least one recess 2A in the retainer 30. In another embodiment, a recess may be formed in each of the extensions 94a and 94b instead of a protrusion 7A, and a protrusion may be formed in the retainer 30 instead of a recess 2A.

[0165] At least two recesses 36A and 36B in the support portion 64 may be provided on the body 93 of the support portion 64 or formed in the body 93 of the support portion 64. For example, at least two recesses 36A and 36B may be formed in a surface of the body 93 facing the drive plate 61.

[0166] Although the support portion 64 is formed to be attached to the retainer 30, the support portion 64 can be implemented as part of the retainer 30. In another embodiment, the support portion 64 can be implemented as an extension extending from the retainer 30. In yet another embodiment, the support portion 64 can be integrally formed with the retainer 30.

[0167] Reference Figure 10a The drive plate 61 can be disposed between the main body 93 of the support portion 64 and the second side portion 28B of the first housing 50. For example, the drive plate 61 can be disposed between the mounting portion 79 of the first housing 50 and the support portion 64. For example, the drive plate 61 can be disposed between the protrusion 57 and the support portion 64. For example, the drive plate 61 can be disposed between the support portion 64 and the magnetic body 63.

[0168] At least a portion of the drive plate 61 may contact, engage, or be in close contact with the first housing 50, and at least another portion of the drive plate 61 may contact, engage, or be in close contact with the support portion 64.

[0169] For example, at least a portion of the drive plate 61 may contact, engage, or be in close contact with the second side 28B of the first housing 50, and at least another portion of the drive plate 61 may contact, engage, or be in close contact with the main body 93 of the support portion 64.

[0170] The drive plate 61 may include a body 61A, a front protrusion 61C that contacts, engages with, or is in close contact with the first housing 50, and a rear protrusion 61B that contacts, engages with, or is in close contact with the support portion 64. For example, the front protrusion 61C may protrude from a first surface of the body 61A facing the first housing 50. The rear protrusion 61B may protrude from a second surface of the body 61A facing the support portion 64. The front protrusion 61C and the rear protrusion 61B may protrude in opposite directions.

[0171] For example, the front protrusion 61C of the drive board 61 may include at least two front protrusions 61C1 and 61C2. For example, the rear protrusion 61B may include at least two rear protrusions 61B1 and 61B2.

[0172] For example, the protrusions 61C1 and 61C2 can be arranged to be spaced apart from each other in a first axial direction or a second direction (e.g., the X-axis direction). Each of the protrusions 61C1 and 61C2 can be disposed in a corresponding one of the first recesses 58A and second recesses 58B in the first housing 50. Each of the protrusions 61C1 and 61C2 can engage or contact a corresponding one of the first recesses 58A and second recesses 58B in the first housing 50. The protrusions 61C1 and 61C2 can define an inclined first axis for the OIS moving unit.

[0173] For example, the rear protrusions 61B1 and 61B2 can be arranged to be spaced apart from each other in a second axial direction or in a third axial direction (e.g., the Y-axis direction). Each of the rear protrusions 61B1 and 61B2 can be disposed in a corresponding one of the first recesses 36A and the second recesses 36B in the support portion 64. Each of the rear protrusions 61B1 and 61B2 can engage or contact a corresponding one of the first recesses 36A and the second recesses 36B in the support portion 64. The rear protrusions 61C1 and 61C2 can define an inclined second axis for the OIS moving unit.

[0174] In another embodiment, the front protrusions of the drive plate 61 may be arranged to be spaced apart from each other in a second axial direction or a third third direction (e.g., the Y-axis direction). In another embodiment, the rear protrusions of the drive plate 61 may be arranged to be spaced apart from each other in a second axial direction or a second direction.

[0175] For example, each of the front protrusion 61C and the rear protrusion 61B may have a curved shape, a hemispherical shape, a dome shape, or a polyhedral shape.

[0176] In another embodiment, instead of the front protrusion, a front recess spaced apart from each other in a first axial direction (or a second axial direction) may be formed in the front surface of the drive plate. Additionally, instead of the first recess 58A and the second recess 58B, a protrusion spaced apart from each other in a second axial direction (or a first axial direction) to engage with the front recess in the drive plate may be formed on the first housing 50.

[0177] In another embodiment, instead of the rear protrusion of the drive plate, a rear recess can be formed in the rear surface of the drive plate, and instead of the first recess 36A and the second recess 36B, a protrusion can be formed on the support 64 to engage with the rear recess in the drive plate.

[0178] In another embodiment, a front recess can be formed instead of the front protrusion of the drive plate, and a rear recess can be formed instead of the rear protrusion of the drive plate. The camera device 200 may include a first ball member (or a first ball) disposed between the recesses 58A and 58B in the first housing 50 and the front recess in the drive plate, and a second ball member (or a second ball) disposed between the rear recess in the drive plate and the recesses 36A and 36B in the support portion 64.

[0179] For example, the drive plate 61 can be formed from an injection-molded material such as plastic or resin. In another embodiment, the drive plate 61 can be formed from a metal (e.g., SUS). Additionally, the drive plate 61 can be non-magnetic. In another embodiment, the drive plate 61 can be magnetic.

[0180] The support joint 60 may include a magnetic body 62 disposed on the OIS moving unit and a magnetic body 63 disposed on the fixing unit. For example, the magnetic body 62 may be disposed on or attached to the retainer 30, and the magnetic body 63 may be disposed in or attached to the first housing 50.

[0181] Reference Figure 9a and Figure 9c The magnetic element 63 may be disposed on the second side portion 28B of the first housing 50. For example, the magnetic element 63 may be disposed on the protrusion 57 of the first housing 50. For example, the magnetic element 63 may be disposed within the recess 44A in the protrusion 57 of the first housing 50. For example, the magnetic element 63 may be bonded to the recess 44a in the first housing 50 using an adhesive.

[0182] Reference Figure 12 and Figure 13 Magnetic bodies 62 and 63 can be arranged to face each other or overlap in a first direction. A repulsive force can act between magnetic bodies 62 and 63. The repulsive force can act between magnetic bodies 62 and 63 in the optical axis direction (or the first direction).

[0183] Each of magnetic bodies 62 and 63 may be formed of a magnetic material. For example, magnetic body 33 may each be a magnet comprising an N pole and a S pole.

[0184] For example, magnetic body 62 may include a first magnet. For example, magnetic body 63 may include a second magnet that exerts a repulsive force on the first magnet.

[0185] Furthermore, the camera device 200 may include a first yoke (not shown) disposed on or attached to the holder 30, and corresponding to, facing, or overlapping the magnetic body 62. The first yoke may be disposed in the mounting portion 37 of the holder 30. For example, the first yoke may be disposed between the bottom surface of the mounting portion 37 and the magnetic body 62.

[0186] Furthermore, the camera device 200 may include a second yoke (not shown) disposed in or attached to the first housing 50, and corresponding to, facing, or overlapping the magnetic body 63. For example, the second yoke may be arranged in the receiving portion 44A of the first housing 50. For example, the second yoke may be disposed between the bottom surface of the receiving portion 44A of the first housing 50 and the magnetic body 63.

[0187] The first and second yokes can be used to increase the magnetic force (e.g., repulsive force) generated between the magnetic body 62 and the magnetic body 63.

[0188] For example, the surfaces of magnetic bodies 62 and 63 facing each other can have the same polarity (N pole or S pole).

[0189] Magnetic bodies 62 and 63 can be disposed between the drive plate 61 and the optical component 40. The drive plate 61 can be disposed between the first housing 50 and the support portion 64. For example, the drive plate 61 can be disposed between the second side 28B of the first housing 50 and the support portion 64. The drive plate 61 can be spaced apart from the retainer 30.

[0190] The optical component 40 can be positioned closer to the magnetic body 62 than the drive plate 61. Additionally, the optical component 40 can be positioned closer to the magnetic body 63 than the drive plate 61. Furthermore, the optical component 40 can be positioned closer to the magnetic body 62 than the magnetic body 63.

[0191] The drive plate 61 may not overlap with the retainer 30 in a direction perpendicular to the first direction. For example, the drive plate 61 may not overlap with the retainer 30 in a second direction. The drive plate 61 may not overlap with the optical component 40 in a direction perpendicular to the first direction. For example, the drive plate 61 may not overlap with the optical component 40 in a second direction.

[0192] At least a portion of the drive plate 61 may overlap with the support portion 64 in a direction perpendicular to the first direction. For example, at least a portion of the drive plate 61 may overlap with the support portion 64 in a second or third direction.

[0193] The distance between the optical component 40 (or the holder 30) and the drive plate 61 can be greater than the distance between the optical component 40 (or the holder 30) and the magnetic body 63 (or the magnetic body 62). For example, the distance between the optical component 40 (or the holder 30) and the drive plate 61 in the first direction can be greater than the distance between the optical component 40 (or the holder 30) and the magnetic body 63 (or the magnetic body 62) in the first direction.

[0194] At least a portion of the drive plate 61 may be located outside the first housing 50. For example, at least a portion of the drive plate 61 may be located outside the second side 28B of the first housing 50.

[0195] Magnetic body 62 can be disposed on the second side 31b of the holder 30, and magnetic body 63 can be disposed on the third side 28B of the first housing 50. Magnetic body 63 can be located between magnetic body 63 and drive plate 61.

[0196] Magnetic elements 62 and 63 may be located inside the first housing 50, and at least a portion of the drive plate 61 may be located outside the first housing 50. Magnetic elements 62 and 63 may be positioned closer to the retainer 30 than the drive plate 61.

[0197] Due to the repulsive force between the magnetic bodies 62 and 63, the drive plate 61 can apply pressure to the support 64 and / or the first housing 50, and can be in close contact with the support 64 and / or the first housing 50.

[0198] Due to the repulsive force acting between the magnetic bodies 62 and 63, the support portion 64 (or the main body 93) can press the drive plate 61. Due to the repulsive force acting between the magnetic bodies 62 and 63, the second side portion 28B (or the mounting portion 79) of the first housing 50 can press the drive plate 61. As a result, the front protrusion 61C and the rear protrusion 61B of the drive plate 61 can come into close contact with the recess 58 in the first housing 50 and the recess 36 in the support portion 64.

[0199] In this embodiment, the drive plate 61 can stably support the retainer 30 because the magnetic force (e.g., repulsion) between the magnetic body 62 and the magnetic body 63 is large, and thus the OIS operation can be stably implemented.

[0200] Reference Figure 12 The length of the magnetic body 62 in the second direction (X-axis direction) can be less than the length of the magnetic body 63 in the second direction. Additionally, refer to... Figure 13 The length of the magnetic body 62 in the third direction (Y-axis direction) can be less than the length of the magnetic body 63 in the third direction. This reduces the size of the magnetic body 62 disposed in the moving unit, thereby reducing the weight of the moving unit and reducing the drive current or power consumption required for OIS driving.

[0201] In another embodiment, the length of the magnetic body 62 in the second direction may be equal to or greater than the length of the magnetic body 63 in the second direction. Additionally, in another embodiment, the length of the magnetic body 62 in the third direction may be equal to or greater than the length of the magnetic body 63 in the third direction.

[0202] For example, the first surfaces of magnetic body 63 and magnetic body 62 may face each other in the optical axis direction. Additionally, the area of ​​the first surface of magnetic body 62 may be smaller than the area of ​​the first surface of magnetic body 63. In another embodiment, the area of ​​the first surface of magnetic body 62 may be equal to or greater than the area of ​​the first surface of magnetic body 63.

[0203] Next, the second drive unit 70 will be described.

[0204] The second drive unit 70 tilts the retainer 30 along a second or third direction, or rotates the retainer 30 by a predetermined angle.

[0205] The second drive unit 70 may include an OIS magnet 31 and an OIS coil 230. The OIS magnet may alternatively be referred to as a "magnet" or "magnet unit," and the OIS coil may alternatively be referred to as a "coil" or "coil unit." Additionally, the second drive unit 70 may include an OIS position sensing unit 240 and a first plate unit 250.

[0206] OIS magnet 31 may be disposed in or attached to retainer 30. For example, OIS magnet 31 may include first OIS magnets 31A and 31B and second OIS magnet 32.

[0207] For example, the first OIS magnet may include a first magnet unit 31A disposed on the third side 31c of the holder 30 and a second magnet unit 31B disposed on the fourth side 31d of the holder 30. For example, the first magnet unit 31A may face or overlap with the second magnet unit 31B in the third direction. For example, the first magnet unit 31A may be disposed in the first mounting recess 16A in the third side 31c of the holder 30, and the second magnet unit 31B may be disposed in the first mounting recess 16A in the fourth side 31d of the holder 30.

[0208] The second OIS magnet may include a third magnet unit 32 disposed on the lower surface 17 of the holder 30. The third magnet unit 32 may be disposed in the second mounting recess 16B in the holder 30.

[0209] Each of the first to third magnet units 31A, 31B, and 32 may be a unipolar magnetized magnet having one N pole and one S pole. However, this disclosure is not limited thereto. In another embodiment, each of the first to third magnet units may be a bipolar magnetized magnet having two N poles and two S poles. In yet another embodiment, at least one of the first to third magnet units 31A, 31B, and 32 may be a unipolar magnetized magnet, and the remaining magnet units may be bipolar magnetized magnets.

[0210] OIS coil 230 may be disposed in the first housing 50. For example, the OIS coil may be configured to correspond to or face the OIS magnet 31. For example, OIS coil 230 may include: first OIS coils 230A and 230B, which correspond to, face, or overlap with the first OIS magnets 31A and 31B in a third direction; and a second OIS coil 230C, which corresponds to, faces, or overlaps with the second OIS magnet 32 ​​in a second direction.

[0211] For example, the first OIS coil may include: a first OIS coil unit 230A that corresponds to, faces, or overlaps with the first magnet unit 31A in a third direction; and a second OIS coil unit 230B that corresponds to, faces, or overlaps with the second magnet unit 31B in a third direction. In another embodiment, the first OIS magnet may include a magnet unit (e.g., either 31A or 31B), and the first OIS coil may include a coil unit (e.g., either 230A or 230B).

[0212] For example, the second OIS coil may include a third OIS coil unit 230C, which corresponds to, faces, or overlaps with the third magnet unit 32 in the second direction.

[0213] For example, the first OIS coil unit 230A may be disposed on the third side 28C of the first housing 50 (e.g., in the first hole 34A), the second OIS coil unit 230B may be disposed on the fourth side 28D of the housing 50 (e.g., in the second hole 54B), and the third OIS coil unit 230C may be disposed on the lower part 28B of the first housing 50 (e.g., in the third hole 54C).

[0214] For example, the first OIS coil unit 230A may have a closed curve or ring shape including a cavity or hole. The first OIS coil unit 230A may be formed as a coil loop wound in a clockwise or counterclockwise direction around a third axis parallel to a third direction.

[0215] The second OIS coil unit 230B may have a closed curve or ring shape including a cavity or hole. The second OIS coil unit 230B may be formed as a coil loop wound in a clockwise or counterclockwise direction around a third axis parallel to the third direction.

[0216] The third OIS coil unit 230C may have a closed curve or ring shape including a cavity or hole. The third OIS coil unit 230C may be formed as a coil loop wound in a clockwise or counterclockwise direction around a second axis parallel to the second direction.

[0217] See Figure 11 Electromagnetic forces F21 and F22 can be generated due to the interaction between the first OIS magnets 31A and 31B and the first OIS coils 230A and 230B. That is, the first electromagnetic force F21 can be generated due to the interaction between the first magnet unit 31A and the first OIS coil unit 230A, and the second electromagnetic force F22 can be generated due to the interaction between the second magnet unit 31B and the second OIS coil unit 230B.

[0218] Furthermore, an electromagnetic force F1 can be generated due to the interaction between the second OIS magnet 32 ​​and the third OIS coil unit 230C.

[0219] Due to electromagnetic forces F21 and F22, the OIS moving unit (e.g., the holder 30) can tilt along a second axis (e.g., the X-axis). In this case, tilting along the second axis (e.g., the X-axis) means that the OIS moving unit tilts relative to the second axis (X-axis) or that the OIS moving unit rotates around the second axis (X-axis) by a predetermined angle.

[0220] Due to the electromagnetic force F1, the OIS moving unit can tilt along a third axis (e.g., the Y-axis). In this case, tilting the third axis (Y-axis) means that the OIS moving unit tilts relative to the third axis or that the OIS moving unit rotates around the third axis by a predetermined angle.

[0221] Furthermore, the first OIS coil unit 230A and the second OIS coil unit 230B can overlap each other in the third direction (Y-axis direction). The first OIS magnet 31A and the second OIS magnet 31B can overlap each other in the third direction. Due to this arrangement, electromagnetic force can be applied to the third side 31c and the fourth side 31d of the holder 30 in a balanced manner, thereby enabling accurate and precise X-axis tilting.

[0222] In another embodiment, the OIS moving unit (e.g., the holder 30) can tilt along a third axis (e.g., the Y-axis) due to the electromagnetic force generated by the interaction between the first OIS magnets 31A and 31B and the first OIS coils 230A and 230B, and can tilt along a second axis (e.g., the X-axis) due to the electromagnetic force generated by the interaction between the second OIS magnet 32 ​​and the third OIS coil unit 230C.

[0223] The camera device 200 may further include yokes 33 (33A, 33B and 33C) disposed on OIS magnets 31 and 32.

[0224] For example, the yoke 33 may include a first yoke 33A disposed on the first magnet unit 31A, a second yoke 33B disposed on the second magnet unit 31B, and a third yoke 33C disposed on the third magnet unit 32.

[0225] For example, the first yoke 33A can be arranged in the first mounting recess 16A in the third side portion 31c of the retainer 30. For example, the first yoke 33A can be disposed further inward than the first magnet unit 31A. The second yoke 33B can be disposed in the first mounting recess 16A in the fourth side portion 31d of the retainer 30. For example, the second yoke 33B can be disposed further inward than the second magnet unit 31B. The third yoke 33C can be disposed in the second mounting recess 16B in the retainer 30. The third yoke 33C can be disposed further inward than the third magnet unit 32. The first yoke 33A and the second yoke 33B can increase electromagnetic forces F21 and F22, and the third yoke 33C can increase electromagnetic force F1.

[0226] The first board unit 250 may be disposed within the first housing 50. For example, the first board unit 250 may be coupled to the first housing 50. The first board unit 250 may be electrically connected to the OIS coil 230 and may provide a drive signal to the OIS coil 230.

[0227] For example, the first OIS coil unit 230A and the second OIS coil unit 230B may be connected in series with each other, and the first board unit 250 may provide a first drive signal to the first OIS coil unit 230A and the second OIS coil unit 230B connected in series with each other. In another embodiment, for example, the first OIS coil unit 230A and the second OIS coil unit 230B may not be connected to each other, and the first board unit 250 may provide an independent drive signal to each of the first OIS coil unit 230A and the second OIS coil unit 230B.

[0228] In addition, the first board unit 250 can provide a second drive signal to the third OIS coil unit 230C.

[0229] The first board unit 250 may include a first circuit board 250A disposed on the third side 28C of the first housing 50, a second circuit board 250B disposed on the fourth side 28D of the first housing 50, and a third circuit board 250C disposed on the lower part 27B of the first housing 50.

[0230] For example, the first circuit board 250A to the third circuit board 250C can be integrated into a single board and can be electrically connected to each other. In another embodiment, at least one of the first to third circuit boards may not be integrated with the remaining circuit boards, but may be electrically connected to the remaining circuit boards.

[0231] The first circuit board 250A may include a hole 251A formed in the first circuit board 250A for engaging with an engagement protrusion 51 on the third side 28C of the first housing 50. Furthermore, the first circuit board 250A may include a plurality of terminals 251.

[0232] The first OIS coil unit 230A may be disposed on or mounted on a first surface of the first circuit board 250A, and a plurality of terminals 251 may be disposed on a second surface of the first circuit board 250A. The first surface of the first circuit board 250A may be a surface facing the outer surface of the third side portion 28C of the first housing 50. The second surface of the first circuit board 250A may be a surface opposite to the first surface of the first circuit board 250A.

[0233] The first board unit 250 may include a curved portion that interconnects the second board 250B and the third board 250C and interconnects the first board 250A and the third board 250C.

[0234] The second circuit board 250B may include a hole 251B formed in the second circuit board 250B for engaging with an engagement protrusion 51 on the fourth side 28D of the first housing 50. The third circuit board 250C may include a hole 251C formed in the third circuit board 250C for engaging with an engagement protrusion 52B on the lower part 28B of the first housing 50.

[0235] The second OIS coil unit 230B can be disposed on or mounted on the first surface of the second circuit board 250B. The first surface of the second circuit board 250B can be a surface facing the outer surface of the fourth side portion 28C of the first housing 50. The third OIS coil unit 230C can be disposed on or mounted on the first surface of the third circuit board 250C. The first surface of the third circuit board 250C can be a surface facing the outer surface of the lower portion 28B of the first housing 50.

[0236] Such a first board unit 250 may include at least one of a rigid printed circuit board (rigid PCB), a flexible printed circuit board (flexible PCB), or a rigid-flexible printed circuit board (rigid-flexible PCB). In addition, the first board unit 250 may include a wiring pattern that electrically connects components disposed on the first board 250A, the second board 250B, and the third board 250C to a plurality of terminals 251.

[0237] The camera device 200 may further include a gyroscope sensor 82 disposed on the first board unit 250. The gyroscope sensor 82 may be electrically connected to the first board unit 250. For example, the gyroscope sensor 82 may be disposed on any of the first to third board units (e.g., 250B).

[0238] For example, the gyroscope sensor 82 can be a 2-axis, 3-axis, or 5-axis gyroscope sensor or an angular velocity sensor.

[0239] The camera device 200 may further include a second driver 260 disposed on the first board unit 250. For example, the second driver 260 may be disposed on or mounted on the first circuit board 250A. For example, the second driver 260 may be disposed within the first housing 50. For example, the second driver 260 may be disposed on or mounted on a first surface of the first circuit board 250A of the first housing 50. The second driver 260 may be disposed on any of the first circuit board 250A to the third circuit board 250C (e.g., 250B). The second driver 260 may be electrically connected to the first board unit 250.

[0240] The second driver 260 can be electrically connected to the first OIS coils 230A and 230B and the second OIS coil 230C. Furthermore, the second driver 260 can be electrically connected to the first OIS position sensors 240A and 240B and the second OIS position sensor 240C.

[0241] For example, the second driver 260 can provide a drive signal to each of the first OIS position sensors 240A and 240B and the second OIS position sensor 240C, and can receive a first output signal from the first OIS position sensors 240A and 240B and a second output signal from the second OIS position sensor 240C.

[0242] Furthermore, for example, the second driver 260 can provide a first drive signal (e.g., drive current or drive voltage) to the first OIS coils 230A and 230B, and can use the first output signal from the first OIS position sensors 240A and 240B to perform feedback control on the first drive signal.

[0243] Furthermore, for example, the second driver 260 can provide a second drive signal (e.g., drive current or drive voltage) to the second OIS coil 230C, and can perform feedback control on the second drive signal using a second output signal from the second OIS position sensor 240C. For example, the second driver 260 may alternatively be referred to as a "driver IC", "OIS driver", "second driver IC", or "OIS controller".

[0244] The OIS position sensing unit 240 can detect the position (or displacement) of the OIS moving unit in a second direction and / or a third direction based on the movement of the OIS moving unit. The OIS position sensing unit 240 can output an output signal corresponding to the result of detecting the position or displacement of the OIS moving unit. The OIS position sensing unit 240 may alternatively be referred to as a "second position sensing unit".

[0245] The OIS position sensing unit 240 may include multiple position sensors. The OIS position sensing unit 240 may be electrically connected to the first board unit 250.

[0246] For example, the OIS position sensing unit 240 may include first OIS position sensors 240A and 240B and a second OIS position sensor 240C.

[0247] The first OIS position sensors 240A and 240B can correspond to, face, or overlap with the first OIS magnet 31 at least partially in a third-party direction, and can detect the strength of the magnetic field of the first OIS magnet 31.

[0248] For example, the first OIS position sensor may include a first sensor 240A disposed or mounted on a first circuit board 250A and a second sensor 240B disposed or mounted on a first board 250-1 of a second circuit board 240B. For example, the first sensor 240A may be disposed in a cavity (or hole) in the first OIS coil unit 230A, and the second sensor 240B may be disposed in a cavity (or hole) in the second OIS coil unit 230B.

[0249] For example, each of the first sensor 240A and the second sensor 240B may be a Hall sensor including a first input terminal and a second input terminal, as well as a first output terminal and a second output terminal.

[0250] The first and second input terminals of the first sensor 240A and the first and second input terminals of the second sensor 240B can be connected in parallel with each other, and the second driver 260 can provide drive signals or power to the first and second input terminals of the first sensor 240A and the second sensor 240B connected in parallel with each other.

[0251] The first and second output terminals of the first sensor 240A and the second output terminals of the second sensor 240B can be connected in series, and a first output signal can be output from both ends of the first and second output terminals of the first sensor 240A and the second sensor 240B connected in series. The first output signal can be transmitted to the second driver 260.

[0252] At least a portion of the second OIS position sensor 240C may correspond to, face, or overlap with the second OIS magnet 32 ​​in the second direction, and may detect the strength of the magnetic field of the second OIS magnet 32.

[0253] For example, the second OIS position sensor 240C may include a third sensor 240C1 and a fourth sensor 240C2 disposed or mounted on the third circuit board 250C. The third sensor 240C1 and the fourth sensor 240C2 may face or overlap with the third OIS magnet 32 ​​in a second direction. For example, the third sensor 240C1 and the fourth sensor 240C2 may be arranged to be spaced apart from each other in a third direction. For example, the third sensor 240C1 and the fourth sensor 240C may be disposed in a cavity (or hole) in the third OIS coil unit 230C.

[0254] For example, each of the third sensor 240C1 and the fourth sensor 240C2 may be a Hall sensor including a first input terminal and a second input terminal, as well as a first output terminal and a second output terminal.

[0255] The first and second input terminals of the third sensor 240C1 and the first and second input terminals of the fourth sensor 240B can be connected in parallel with each other, and the second driver 260 can provide drive signals or power to the first and second input terminals of the third sensor 240C1 and the fourth sensor 240C2 connected in parallel with each other.

[0256] The first and second output terminals of the third sensor 240C1 and the first and second output terminals of the fourth sensor 240C2 can be connected in series with each other, and a second output signal can be output from both ends of the first and second output terminals of the third sensor 240C1 and the fourth sensor 240C2 connected in series. The second output signal can be transmitted to the second driver 260.

[0257] In another embodiment, the output terminals of each of the first and second sensors can be configured independently without being connected to each other, and can output independent output signals. Furthermore, the output terminals of each of the third and fourth sensors can be configured independently without being connected to each other, and can output independent output signals.

[0258] In yet another embodiment, the first OIS position sensor may include a position sensor (e.g., a Hall sensor or a driver IC including a Hall sensor) and may transmit the output from the position sensor to the driver 260. Additionally, the second OIS position sensor may include a position sensor (e.g., a Hall sensor or a driver IC including a Hall sensor) and may transmit the output from the position sensor to the driver 260.

[0259] In a comparative example, the drive plate 61 may be disposed inside the first housing 50 and between the retainer 30 and the first housing 50. In a comparative example, the drive plate that supports and guides tilting may be disposed close to the retainer (or optical component) to be tilted.

[0260] In this embodiment, since the drive plate 61 is located outside the first housing 50, the drive plate 61 can be positioned further away from the OIS movement unit (e.g., the holder 30 (or optical component 40)) than in the comparative example. That is, the drive plate 61 can be positioned further away from the target (holder 30 or optical component 40) that needs to be tilted for shaky compensation.

[0261] In this embodiment, since the drive board is positioned far from the OIS moving unit, the movement distance of the OIS moving unit required for hand shake compensation can be reduced.

[0262] In other words, when the OIS moving unit tilts within a predetermined angle range (e.g., 1 degree compensation) to achieve hand shake compensation, the moving distance (rotation distance or tilt angle) of the OIS moving unit in the embodiment can be smaller than the moving distance (rotation distance or tilt angle) of the OIS moving unit in the comparative example. In the embodiment, because the moving distance (rotation distance or tilt angle) is small, the power consumption required for hand shake compensation can be reduced.

[0263] In addition, in the embodiment, the moving distance of the OIS moving unit required for hand shake compensation can be designed to be small, so the drive board 61 can be designed to have a large size.

[0264] Furthermore, in this embodiment, since the movement distance of the OIS moving unit can be designed to be relatively small, the size of the camera device 200 can be reduced. Additionally, in this embodiment, since the drive plate 61 can be designed to have a larger size, it can stably support and guide the OIS moving unit during OIS driving.

[0265] Furthermore, the drive plate 61 does not directly contact the retainer 30, and the drive plate 61 and the retainer 30 do not collide directly with each other during impact. Therefore, damage to the retainer 30 and the optical component 40 caused by collision with the drive plate 61 can be suppressed or prevented.

Figure 16 is a second perspective view of the first guide portion 614A, the second guide portion 614B, and the lens unit 620. Figure 20 This is an exploded perspective view of the first magnet 130A, the second magnet 130B, and the lens unit 620.

[0267] Reference Figures 14 to 20 The first actuator 310 may include a second housing 610, a lens unit 620 disposed in the second housing 610, and a first drive unit 630 configured to move the lens unit 620 in a first direction (e.g., the optical axis direction or the Z-axis direction).

[0268] Lens unit 620 may alternatively be referred to as a "lens assembly". For example, lens unit 620 may include multiple lens assemblies.

[0269] Although lens unit 620 is Figures 14 to 2 The image shows two lens assemblies, 622 and 624, but this disclosure is not limited thereto. For example, a second lens assembly 622 and a third lens assembly 623 may be arranged in the first direction.

[0270] The first actuator 310 may further include a first lens assembly 640 disposed between the lens unit 620 and the second actuator 320. For example, the first lens assembly 640 may be a fixed lens assembly that is fixed in position and does not move in the optical axis direction.

[0271] The first lens assembly 640 may include a first lens array 642 (or a first lens group). For example, the first lens assembly 640 may further include a lens barrel 641 coupled to the first lens array 642. Furthermore, the first lens assembly 640 may further include a third housing 643 coupled to the lens barrel 641. The third housing 643 may be disposed between the second housing 610 and the first housing 50, and may be coupled to at least one of the second housing 610 and the first housing 50.

[0272] For example, at least one first engagement hole 643A may be formed in the front surface of the third housing 643 to engage with at least one engagement protrusion 46A of the second housing 610. Additionally, a second engagement hole may be formed in the rear surface of the third housing 643 to engage with at least one engagement protrusion 52A of the first housing 50.

[0273] Although the first lens assembly 640 is described as being included in the first actuator 310, this disclosure is not limited thereto. The first lens assembly may not be included in the first actuator 310. In another embodiment, the first lens assembly 640 may be omitted.

[0274] In another embodiment, any one of 640, 622, and 624 may be referred to as the "first lens assembly", another of 640, 622, and 624 may be referred to as the "second lens assembly", and the remaining one of 640, 622, and 624 may be referred to as the "third lens assembly".

[0275] For example, in an embodiment, the first lens assembly 640 may be a fixed lens group, and each of the second lens assembly 622 and the third lens assembly 624 may include a movable lens group or a lens group.

[0276] For example, the first lens assembly 640 can function as a focuser that focuses parallel light to form an image at a specific location. Additionally, the second lens assembly 622 can function as a transducer that re-forms the image formed by the first lens assembly 640 (which is the focuser) at another location. On the other hand, due to large variations in distance to the object or image distance, the magnification of the second lens assembly 622 can change significantly. As a transducer, the second lens assembly 622 can play a crucial role in altering the focal length or magnification of the optical system. Furthermore, the image point formed by the second lens assembly 6220 as a transducer can vary slightly depending on the position of the second lens assembly.

[0277] Additionally, the third lens assembly 624 can perform position compensation on the image formed by the transducer. For example, the third lens assembly 624 can function as a compensator that accurately forms image points on the pixels of the image sensor 540 formed by the second lens assembly 622, which acts as a transducer.

[0278] For example, the second lens assembly 622 may be a zoom lens assembly that performs a zoom function, and the third lens assembly 624 may be a focusing lens assembly that performs a focusing function.

[0279] Reference Figure 2 , Figure 14 , Figure 15a and Figure 15b The second housing 610 may be disposed between the first housing 50 and the image sensor unit 330 (e.g., sensor base 550). The second housing 610 may alternatively be referred to as a "base" or "retainer".

[0280] The second housing 610 may be disposed inside the cover member 300 and may have a polyhedral (e.g., cuboid) shape with a space defined therein to accommodate the lens unit 620 and the first drive unit 630.

[0281] For example, the second housing 610 may include a main body 612, which includes an upper portion 142A (or upper plate), a lower portion 142B (or lower plate), and a plurality of side portions 141-1 to 141-4 disposed between the upper portion 142A and the lower portion 142B. The upper portion 142A of the second housing 610 may face the upper plate 301 of the cover member 300, and the side portions 141-1 to 141-4 may face the side plate 302 of the cover member 300.

[0282] Side portions 141-1 to 141-4 may alternatively be referred to as “side plates” or “side walls”. For example, the first side portion 141-1 and the second side portion 141-2 may face each other or be disposed opposite each other in a first direction, and the third side portion 141-3 and the fourth side portion 141-3 may face each other or be disposed opposite each other in a third direction.

[0283] A first opening 41A (or a first hole) may be formed in the first side portion 141-1 of the second housing 610 to expose one end of the lens unit 620, and a second opening 41B (or a second hole) may be formed in the second side portion 141-2 of the second housing 610 to expose the other end of the lens unit 620.

[0284] Furthermore, a third opening 41C (or a third hole) for housing or disposed of the first coil 120A may be formed in the third side portion 141-3 of the second housing 610, and a fourth opening 41C (or a third hole) for housing or disposed of the second coil 120B may be formed in the fourth side portion 141-4 of the second housing 610. Each of the third opening 41C and the fourth opening 41D may have a through-hole shape, but is not limited thereto. Each of the third opening and the fourth opening may have a recessed shape.

[0285] At least one first engagement protrusion 45A may be formed on the third side portion 141-3 of the second housing 610 to engage with the first circuit board 192 of the second board unit 190. For example, at least one first engagement protrusion 45A may protrude from the outer surface of the third side portion 141-3.

[0286] At least one second engagement protrusion 45B may be formed on the fourth side portion 141-1 of the second housing 610 to engage with the second circuit board 194 of the second board unit 190. For example, at least one second engagement protrusion 45B may protrude from the outer surface of the fourth side portion 141-4. In addition, at least one third engagement protrusion 46A may be formed on the second side portion 141-2 of the second housing 610.

[0287] The second housing 610 may include a first guide portion 614A and a second guide portion 614B. When the lens unit 620 moves to perform a zoom operation, the first guide portion 614A can support and guide the second lens assembly 622. When the lens unit 620 moves to perform a zoom operation, the second guide portion 614B can support and guide the third lens assembly 624.

[0288] The first guide portion 614A can be disposed between the lens unit 620 and the third side portion 141-3, and the second guide portion 614b can be disposed between the lens unit 620 and the fourth side portion 141-4.

[0289] For example, the first guide portion 614A can be attached to the third side portion 141-3 of the second housing 610, and the second guide portion 614B can be attached to the fourth side portion 141-4 of the second housing 610.

[0290] Reference Figure 19a and Figure 19b The first guide portion 614A may include at least one first guide groove 212A. The second guide portion 614B may include at least one second guide groove 212B. Here, the guide groove may alternatively be referred to as a "track" or "groove".

[0291] For example, each of the first guide portion 614A and the second guide portion 614B may include a body 63A and a protrusion 63B protruding from the body 63A.

[0292] For example, the first guide groove 212A may be formed in the inner surface of the body 63A of the first guide portion 614A, and the second guide groove 212B may be formed in the inner surface of the body 63A of the second guide portion 614B. In this case, the inner surface of the body 63A of each of the first guide portion 614A and the second guide portion 614B may be the surface facing the lens unit 620.

[0293] exist Figure 19a and Figure 19b In this embodiment, a first guide groove 212A is formed on the lower side of the inner surface of the body 63A of the first guide portion 614A, and a second guide groove 212B is formed on the upper side of the inner surface of the body 63A of the second guide portion 614B. However, this disclosure is not limited thereto. In another embodiment, the guide grooves may be formed in at least one of the upper and lower sides of the inner surface of the body of each of the first and second guide grooves. For example, each of the first guide groove 212A and the second guide groove 212B may be continuously formed from the front end to the rear end of the inner surface of the body 64A.

[0294] The protrusion 63B of each of the first guide portion 614A and the second guide portion 614B may extend in a direction perpendicular to the direction in which the first guide groove and the second guide groove extend (e.g., a first direction) (e.g., a third direction). For example, the protrusion 63B of the first guide portion 614A and the protrusion 63B of the second guide portion 614B may protrude in opposite directions. For example, the protrusion 63B may be formed on the rear surface or rear end of each of the first guide portion 614A and the second guide portion 614B.

[0295] At least one hole 68 may be formed in the protrusion 63B of each of the first guide portion 614A and the second guide portion 614B to engage with the rear end of the body 612 of the second housing 610. For example, the hole 68 in the protrusion 63B may engage with the engagement protrusion 46A of the body 612 of the second housing 610. For example, the engagement protrusion 46A may engage with the first engagement hole 643A in the third housing 643 through the hole 68 in the protrusion 63B.

[0296] At least one engaging protrusion 6A may be formed on the front surface or front end of each of the first guide portion 614A and the second guide portion 614B to engage with the body 612 of the second housing 610. For example, engaging holes 6B may be formed in the inner surface of the body 612 of the second housing 610 to engage with the engaging protrusion 6A of each of the first guide portion 614A and the second guide portion 614B (see reference). Figure 18b ).

[0297] Reference Figure 18b Guide protrusions 44A to 44D may be formed on the inner surface of the main body 612 of the second housing 610 to guide the first guide portion 614A and the second guide portion 614B. For example, the first guide protrusion 44A may be provided on the inner surface of the lower portion 142B of the second housing 610, and the second guide protrusion 44B may be provided on the inner surface of the upper portion 142A of the second housing 610 to correspond to the first guide protrusion 44A in a second direction. The first guide portion 614A may be provided in the space 49A between the first guide protrusion 44A and the second guide protrusion 44B and the third side portion 141-3 of the second housing 610.

[0298] Alternatively, for example, a third guide protrusion 44C may be disposed on the inner surface of the lower portion 142B of the second housing 610, and a fourth guide protrusion 44D may be disposed on the inner surface of the upper portion 142A of the second housing 610, corresponding to the third guide protrusion 44C in the second direction. A second guide portion 614B may be disposed in the space 49B between the third guide protrusion 44C and the fourth guide protrusion 44D and the fourth side portion 141-4 of the second housing 610.

[0299] Due to the first guide protrusion 44A to the fourth guide protrusion 44D, the first guide portion 614A and the second guide portion 614B can be stably attached to the body of the second housing 610, and can prevent the first guide portion 614A and the second guide portion 614B from deviating from their original position or colliding with the lens unit 620 due to impact.

[0300] The first guide portion 614A may include a first opening 67A (or hole) formed in the first guide portion 614A to correspond to, face, or overlap with the first magnet 130A. For example, the first opening 67A may be located between the first magnet 130A and the first coil 120A.

[0301] The second guide portion 614B may include a second opening 67B (or hole), which is formed in the second guide portion 614B to correspond to, face, or overlap with the second magnet 130B. For example, the first opening 67B may be located between the second magnet 130B and the second coil 120B. The electromagnetic force generated by the interaction between the first magnet 130A and the first coil 120A, and the electromagnetic force generated by the interaction between the second magnet 130B and the second coil 120B, can be amplified by the first opening 67A and the second opening 67B.

[0302] exist Figure 18a and Figure 18bIn this embodiment, the first guide portion 614A, the second guide portion 614B, and the main body 612 of the second housing 610 are formed as separate injection-molded products, and the separate injection-molded products are coupled together. However, this disclosure is not limited thereto. In another embodiment, the first guide portion, the second guide portion, and the main body of the second housing can be formed as a single injection-molded product.

[0303] An opening 621 may be formed in the upper portion 142A of the body 612 of the second housing 610 to expose a portion of the lens unit 620, and the second housing 610 may further include a cover 614 covering the opening 621. In another embodiment, the opening 621 may not be formed, and the cover 614 may be omitted.

[0304] The lens unit 620 may include a second lens assembly 622 configured to move along the first guide 614A and a third lens assembly 624 configured to move along the second guide 614B.

[0305] Reference Figure 19a , Figure 19b and Figure 20 The second lens assembly 622 may include a first lens holder 29 and a second lens array 49 (or second lens group) disposed in the first lens holder 29. The lens holder may alternatively be referred to as a "bowl".

[0306] The second lens array 49 may include a single lens or multiple lenses.

[0307] The first lens holder 29 may include a first lens barrel 29A in which a second lens array 49 is disposed and a first support portion 29B coupled to the first lens barrel 29A. For example, the first lens barrel 29A may have a barrel shape and may include an opening 29C (or hole) formed therein, through which the second lens array 49 is coupled to the first lens barrel 29A.

[0308] The first side surface (or first surface) of the first support portion 29B can be attached to the first lens barrel 29A. The first support portion 29B can correspond to, face, or overlap with the main body 63A of the first guide portion 614A in a third direction.

[0309] The first mounting portion 30A, in which the first magnet 130A is disposed or placed, may be formed in the second side surface (or second surface) of the first support portion 29B. The second side surface (or second surface) of the first support portion 29B may be the surface facing the first guide portion 614A, and may be the surface opposite to the first side surface (or first surface) of the first support portion 29B.

[0310] For example, the first mounting portion 30A may include a first mounting surface 11A formed in a region (e.g., a central region) of the second side surface (or second surface) of the first support portion 29B, and at least one first support protrusion 11B protruding from the first mounting surface 11A. In FIG. 18, the first mounting portion 30A may include four first support protrusions formed at the four corners of the second side surface of the first support portion 29B, and the four first support protrusions may support the first magnet 130A. In another embodiment, the number of first support protrusions of the first mounting portion may be one, two, or more.

[0311] The first support portion 29B may include at least one first groove 13A (or first guide groove), which is formed therein to receive at least a portion of the first rolling member 12A. For example, at least one first groove 13A may correspond to, face, or overlap with at least one first guide groove 212A in the first guide portion 614A.

[0312] For example, two first grooves spaced apart from each other may be formed above the mounting surface 11A of the first mounting portion 30A, and two first grooves spaced apart from each other may be formed below the mounting surface 11B. In another embodiment, two grooves formed above or below the mounting surface 11B may be connected to each other to form a single groove. For example, the number of grooves may be the same as the number of balls B11 to B14. However, this disclosure is not limited thereto.

[0313] The third lens assembly 624 may include a second lens holder 39 and a third lens array 59 (or a third lens group) disposed in the second lens holder 39. The third lens array 59 may include a single lens or multiple lenses.

[0314] The plurality of lenses included in each of the second lens array 49 and the third lens array 59 may be sequentially arranged or configured in the first direction. For example, each of the second lens array 49 and the third lens array 59 may include various types of optical lenses. For example, each of the second lens array 49 and the third lens array 59 may include at least one of a front lens having positive optical power and a rear lens having negative optical power.

[0315] The distance between the second lens group and the third lens group in the optical axis direction can be changed by the first drive unit 630.

[0316] The second lens holder 39 may include a second lens barrel 39A in which a third lens array 59 is disposed and a second support portion 39B coupled to the second lens barrel 39A. For example, the second lens barrel 39A may have a barrel shape and may include an opening 39C (or hole) formed therein, through which the second lens array 49 is coupled to the second lens barrel 39A.

[0317] The first side surface (or first surface) of the second support portion 39B can be attached to the second lens barrel 39A. The second support portion 39B can correspond to, face, or overlap with the main body 63A of the second guide portion 614B in a third direction.

[0318] The second mounting portion 30B, in which the second magnet 130B is disposed or placed, may be formed in the second side surface (or second surface) of the second support portion 39B. The second side surface (or second surface) of the second support portion 39B may be the surface facing the second guide portion 614B, and may be the surface opposite to the first side surface (or first surface) of the second support portion 39B.

[0319] For example, the second mounting portion 30B may include a second mounting surface formed in a region (e.g., a central region) of the second side surface (or second surface) of the second support portion 39B and at least one second support protrusion protruding from the second mounting surface. The description of the first mounting surface 11A and the first support protrusion 11B of the first support portion 29B can be applied in the same or similar way to the second mounting surface and the second support protrusion of the second support portion 29B.

[0320] The second support portion 39B may include at least one second groove 13B (or a second guide groove) formed in the second support portion 39B to receive at least a portion of the second rolling member 12B. For example, at least one second groove 13B may correspond to, face, or overlap with at least one second guide groove 212B in the second guide portion 614B. The description of the first groove 13A in the first support portion 30A can be applied in the same or similar way to the second groove 13B in the second support portion 30B.

[0321] Each of the first guide groove 212A and the second guide groove 212B, as well as the first groove 13A and the second groove 13B, may be V-shaped or U-shaped. However, this disclosure is not limited thereto. Each groove may be shaped to contact balls B11 to B14 and B21 and B24 at two or more locations. When the second lens assembly 622 and the third lens assembly 624 move, their eccentricity or tilting can be prevented by the first guide groove 212A and the second guide groove 212B, as well as the first groove 13A and the second groove 13B. Therefore, the multiple lens arrays can be well aligned with each other, thereby preventing changes in viewing angle or defocusing, and thus significantly improving the image quality or resolution of the camera device 200.

[0322] The first actuator 310 may further include rolling members 12A and 12B disposed between the second housing 610 and the lens unit 620. For example, the rolling members 12A and 12B may be disposed between the guide portions 614A and 614B of the second housing 610 and the grooves 13A and 13B in the support portions 39A and 39B of the lens unit 620.

[0323] Rolling members may be alternatively referred to as "ball members," "balls," or "ball bearings." For example, each of rolling members 12A and 12B may include at least one ball.

[0324] Rolling members 12A and 12B can contact the second housing 610 and the lens unit 620, and can support the lens unit 620. When the lens unit 620 moves in the first direction, the rolling members 12A and 12B can perform rolling motion between the lens unit 620 and the second housing 610, thereby reducing the friction between the lens unit 620 and the second housing 610. That is, due to the rolling motion of the rolling members 12A and 12B, the lens unit 620 can slide along the first guide portion 614A and the second guide portion 614B in the first direction while in contact with the rolling members 12A and 12B.

[0325] For example, the rolling members may include a first rolling member 12A and a second rolling member 12B. The first rolling member 12A may be disposed between a first guide portion 614A of the second housing 610 and a second lens assembly 622 (e.g., a first support portion 29B). The second rolling member 12B may be disposed between a second guide portion 614B of the second housing 610 and a third lens assembly 624 (e.g., a second support portion 39B).

[0326] The first rolling member 12A may include a plurality of balls B11 to B14, and the second rolling member 12B may include a plurality of balls B21 to B24. Each of balls B11 to B14 and B221 to B24 may be made of metal, plastic, or resin. However, this disclosure is not limited thereto. Each of balls B11 to B14 and B221 to B24 may have a circular shape and may have a diameter large enough to support the movement of the lens unit 620.

[0327] Next, the first drive unit 630 will be explained.

[0328] The first drive unit 630 can move the second lens assembly 622 in the first direction and can also move the third lens assembly 624 in the first direction. For example, the first drive unit 630 can move at least one lens group, such as the second lens group or the third lens group, in the first direction or the optical axis direction.

[0329] The first drive unit 630 may include a magnet 130 disposed in the lens unit 620 and a coil 120 disposed in the second housing 610. For example, the magnet 130 may include a first magnet 130A disposed on the second lens assembly 622 and a second magnet 130B disposed on the third lens assembly 624.

[0330] For example, the first magnet 130A can be disposed on the first lens holder 29 of the second lens assembly 622, and the second magnet 130B can be disposed on the second lens holder 39 of the third lens assembly 624. For example, the first magnet 130A can be disposed in the first placement portion 30A of the first support portion 29B of the first lens holder 29, and the second magnet 130B can be disposed in the second placement portion 30B of the second support portion 39B of the second lens holder 39.

[0331] For example, each of the first magnet 130A and the second magnet 130B can be a unipolar magnetized magnet including one N pole and one S pole. In another embodiment, each of the first magnet 130A and the second magnet 130B can be a bipolar magnetized magnet including two N poles and two S poles.

[0332] The coil 120 may include a first coil 120A and a second coil 120B. The first coil 120A is disposed on the third side 142-3 of the second housing 610 in a third direction, corresponding to, facing or overlapping with the first magnet 130A. The second coil 120B is disposed on the fourth side 142-4 of the second housing 610 in a third direction, corresponding to, facing or overlapping with the second magnet 130B.

[0333] For example, each of the first coil 120A and the second coil 120B may have a closed curve or a loop shape including a cavity (or hole). For example, each of the first coil 120A and the second coil 120B may be formed as a coil loop wound in a clockwise or counterclockwise direction relative to (or around) a third axis parallel to a third direction.

[0334] For example, the N and S poles of the first magnet 130A can be configured to face the first coil 120A, and the N and S poles of the second magnet 130B can be configured to face the second coil 120B. For example, the cavity or hole in each of the first coil 120A and the second coil 120B can face the first magnet 130A and the second magnet 130B in a third-party orientation.

[0335] A first driving signal (e.g., a first current) can be applied to the first coil 120A, and a second driving signal (e.g., a second current) can be applied to the second coil 120B. The first lens assembly 622 can be moved in a first direction by the electromagnetic force generated by the interaction between the first coil 120A and the first magnet 130A. Additionally, the second lens assembly 624 can be moved in a first direction by the electromagnetic force generated by the interaction between the second coil 120B and the second magnet 130B.

[0336] The movement of each of the first lens assembly 622 and the second lens assembly 624 can be controlled by controlling the first drive signal and the second drive signal. When the movement of each of the first lens assembly 622 and the second lens assembly 624 is controlled, the position (or displacement) of each of the first lens assembly 622 and the second lens assembly 624 can be controlled, and therefore, zooming and autofocusing of the camera device 200 can be performed.

[0337] Reference Figure 20 The first driving unit 630 may further include a first yoke 19-1 disposed on the first lens holder 29 and a second yoke 19-2 disposed on the second lens holder 39.

The first yoke 19-1 and the second yoke 19-2 may improve the driving force for moving the lens unit 620, thereby reducing power consumption.

[0338] For example, the first yoke 19-1 can be disposed between the first magnet 130A and the first lens holder 29, and the second yoke 19-2 can be disposed between the second magnet 130B and the second lens holder 39. For example, the first yoke 19-1 can be disposed in the first placement portion 30A of the first support portion 29B, and the second yoke 19-2 can be disposed in the second placement portion 30B of the second support portion 39B.

[0380] In another embodiment, at least one of the second plate 532 and the connector 534 may be omitted, and a port or socket may be formed on the first plate. In yet another embodiment, a port or socket may be formed on at least one of the first to third plates.

[0381] The image sensing unit 330 may further include a first driver 542 disposed on the third board unit 530. The first driver 542 may be disposed on or mounted on the first board 531. For example, the first driver 542 may be disposed between the image sensor 540 and a plurality of second terminals 253B.

Additionally, for example, each of the first driver 542 and the second driver 260 may include a storage unit or memory.

[0394] Figures 14 to 20 The illustrated embodiment includes a zoom lens assembly 622 that performs a zoom function and a focusing lens assembly 624 that performs an autofocus function. In another embodiment, the zoom lens assembly 622 may be omitted, and the focusing lens assembly 624 may be included. For example, in another embodiment, the first actuator may be a fixed zoom actuator that performs an autofocus function.

[0395] Figure 21 This is a functional block diagram of the camera device 200 according to an embodiment.

[0396] Reference Figure 21 The camera device 200 may include a first driving unit 630, a second driving unit 70, a first position sensing unit 170, a second position sensing unit 240, a storage unit 180, an image sensing unit 600, and a controller 810.

[0397] The first drive unit 630 receives a first drive signal, applies the received first drive signal to the first coil 120A, and causes the second lens assembly 622 to move in a first direction through the interaction between the first coil 120A and the first magnet 130A.

[0398] Furthermore, the first drive unit 630 receives a second drive signal, applies the received second drive signal to the second coil 120B, and causes the third lens assembly 624 to move in the first direction through the interaction between the second coil 120B and the second magnet 130B.

[0399] The second drive unit 70 receives the first OIS drive signal, applies the received first OIS drive signal to the first OIS coils 230A and 230B, and causes the OIS moving unit (e.g., holder 30) to rotate around the second axis (e.g., X-axis) by a predetermined angle through the interaction between the first OIS coils 230A and 230B and the first OIS magnets 31A and 31B.

[0400] In addition, the second drive unit 70 receives the second OIS drive signal, applies the received second OIS drive signal to the second OIS coil 230C, and causes the OIS moving unit (e.g., the holder 30) to rotate around the third axis (e.g., the Y axis) by a predetermined angle through the interaction between the second OIS coil 230C and the second OIS magnet 32.

[0401] Because of the movement of the holder 30, which is connected to the optical component 40 via the second drive unit 70, the path of light introduced into the optical component 40 can move in a plane (e.g., the XY plane) perpendicular to the first axis (optical axis or Z-axis), and therefore, the image formed on the image sensor 540 can move in the X-axis direction and / or the Y-axis direction. That is, in the embodiment, image blurring or motion image jitter can be corrected by controlling the movement of the holder 30, wherein image blurring or motion image jitter is caused by camera device shaking due to the user's hand shaking when capturing an image or moving image.

[0402] The first position sensing unit 170 receives a first driving signal and provides the received first driving signal to the first sensor 71A and the second sensor 71B. The first position sensing unit 170 receives a second driving signal and provides the received second driving signal to the third sensor 72A and the fourth sensor 72B.

[0403] The first position sensing unit 170 detects the displacement of the second lens assembly 622 and outputs a first output signal corresponding to the detection result. Furthermore, the first position sensing unit 170 detects the displacement of the third lens assembly 624 and outputs a second output signal corresponding to the detection result.

[0404] The second position sensing unit 240 provides a drive signal to each of the first sensor 240A and the second sensor 240B of the first OIS position sensor and the second OIS position sensor 240C. The first OIS position sensors 240A and 240B can detect the displacement of the OIS moving unit (e.g., the holder 30) in the third axis direction and can output an output signal corresponding to the detection result. The second OIS position sensor 240C can detect the displacement of the OIS moving unit (e.g., the holder 30) in the second axis direction and can output an output signal corresponding to the detection result. For example, the displacement in the third axis direction can be the tilt position or displacement of the OIS moving unit relative to the second axis, and the displacement in the second axis direction can be the tilt position or displacement of the OIS moving unit relative to the third axis.

[0405] Storage unit 180 stores data required for operating camera device 200. Storage unit 180 may also be referred to as "memory". For example, information about zoom position and focus position corresponding to the distance to the object can be stored in storage unit 180.

[0406] For example, storage unit 180 may store a first reference code value (or data) relating to a first output signal from the first position sensing unit 71 corresponding to the range of motion (travel range or displacement) of the second lens assembly 622. Additionally, storage unit 180 may store a second reference code value (or data) relating to a second output signal from the second position sensing unit 72 corresponding to the range of motion (travel range or displacement) of the third lens assembly 624. The first and second reference code values ​​may be values ​​pre-stored in storage unit 180 through calibration.

[0407] Storage unit 180 may be disposed separately from controller 810. However, this disclosure is not limited thereto. In another embodiment, storage unit 180 may be included in controller 810. For example, storage unit 180 may be included in at least one of first drive 542 and second drive 260.

[0408] For example, the camera device 200 can be accurately focused based on the target position of the second lens assembly 622 and the target position of the third lens assembly 624.

[0409] The image sensing unit 330 may include an image sensor 540 configured to convert light reflected from an object into an electrical signal. For example, the image sensor 540 may include a light receiver configured to receive light and convert the received light into an electrical signal, and an analog-to-digital converter configured to convert the converted electrical signal into a digital signal. Additionally, for example, the image sensor 540 may further include an image signal processor configured to perform signal processing on the digital signal.

[0410] The controller 810 controls the overall operation of the camera device 200. For example, the controller 200 can control the first position sensing unit 170 and the second position sensing unit 240, and can drive the first drive unit 630 and the second drive unit 70 to provide image stabilization, autofocus, and zoom functions. For example, the controller 810 may include a first driver 542 and a second driver 260. For example, each of the first driver 542 and the second driver 260 may include at least one of an analog-to-digital converter, an amplifier, a PID controller, or a memory.

[0411] The first driver 542 can receive an output signal from the first position sensing unit 170, generate a first code value corresponding to the result of analog-to-digital conversion of the received output signal, and control the drive signal applied to the first coil 120 of the first drive unit 630 based on the comparison result between the generated first code value and a first target value. For example, the first target value may be a reference code value corresponding to the target zoom position of the second lens assembly 622.

[0412] The second driver 260 can receive output signals from the first OIS position sensors 240A and 240B of the second position sensing unit 240, generate a second code value corresponding to the analog-to-digital conversion result of the received output signal, and control the first drive signal applied to the first OIS coils 230A and 230B of the second drive unit 70 based on the comparison result between the generated second code value and the second target value.

[0413] Furthermore, the second driver 260 can receive the output signal from the second OIS position sensor 240C of the second position sensing unit 240, generate a third code value corresponding to the result of analog-to-digital conversion of the received output signal, and control the second drive signal applied to the second OIS coil 230C of the second drive unit 70 based on the result of comparing the generated third code value with the third target value.

[0414] For example, the second target value could be a reference code value (or data) from the outputs of the first OIS position sensors 240A and 240B corresponding to the target second axis (X-axis) tilt position of the OIS movement unit of the second actuator 320. Additionally, for example, the third target value could be a reference code value (or data) from the output of the second OIS position sensor 240C corresponding to the target third axis (Y-axis) tilt position of the OIS movement unit of the second actuator 320. The reference code values ​​(or data) from the outputs of each of the first OIS position sensors 240A and 240B and the second OIS position sensor 240C can be preset through calibration and stored in the storage unit 180.

[0415] The camera device 200 may further include a temperature sensor 566 for temperature compensation. The temperature sensor 566 can output temperature information corresponding to the result of measuring the temperature of the camera device 200.

[0416] Temperature information from temperature sensor 566 can be used for temperature compensation during the focusing operation of third lens assembly 624. For example, storage unit 180 can store compensation values ​​corresponding to the temperature information.

[0417] For example, since the second lens assembly 622, which is responsible for zooming, moves according to the magnification set by the user, temperature compensation for the third lens assembly 624, which is responsible for autofocus, can be performed while the position of the second lens assembly 622 remains fixed (or conditional).

[0418] Additionally, for example, the controller 810 can receive temperature information from the temperature sensor 566, obtain a temperature compensation value corresponding to the received temperature information, and control the drive signal of the second coil 120B of the third lens assembly 624 based on the obtained compensation value. Therefore, in this embodiment, accurate autofocus operation reflecting temperature compensation can be implemented.

[0419] Furthermore, the camera device 200 according to the embodiment may be included in an optical instrument for the purpose of forming an image of an object existing in space using reflection, refraction, absorption, interference, and diffraction as properties of light, for the purpose of increasing visibility, for the purpose of recording and reproducing an image using a lens, or for the purpose of optical measurement or image propagation or transmission.

For example, when the terminal 200A is a slider phone, it can detect whether the slider phone is on or off. In addition, the sensing unit is used to sense whether power is supplied from the power supply unit 790 or whether the interface unit 770 is connected to an external device.

[0432] The memory 760 can store programs for processing and control by the controller 780, and can temporarily store input / output data (e.g., phone book, messages, audio, still images, pictures, and moving images). For example, the memory 760 can store images captured by the camera 721, such as pictures or moving images.
