Description

Camera devices and optical instruments

[0001] The embodiment relates to a camera device and an optical device including the same.

[0002] Camera devices are devices that capture images or videos of subjects, and are installed on portable devices, drones, vehicles, etc. To improve image quality, camera devices may have image stabilization (IS) functions, such as optical image stabilizers (OIS) and autofocusing (AF), which compensate for or prevent image shaking caused by the user's movements.

[0003] The embodiment provides a camera device and optical device capable of reducing the size of the camera device, implementing high-resolution images, and reducing manufacturing costs.

[0004] A camera device according to an embodiment includes a fixed part; a moving part including a sensor base, an image sensor disposed on the sensor base, a lens holder disposed on the image sensor and coupled with the sensor base, and a lens coupled with the lens holder; a tilting guide part disposed between the sensor base and the fixed part; and a driving part that tilts the moving part based on a first axis perpendicular to an optical axis direction or a second axis intersecting the optical axis direction and the first axis.

[0005] The above lens holder may not be movable in the optical axis direction relative to the sensor base.

[0006] The sensor base may include at least one protrusion protruding from the upper surface, and the lens holder may include a groove that engages with the protrusion of the sensor base. The camera device may include a filter that engages with the lens holder and is positioned between the lens module and the image sensor.

[0007] The driving unit may include a magnet disposed on one of the fixed unit and the lens holder; and a coil disposed on the other of the fixed unit and the lens holder.

[0008] The magnet may include a first magnet unit and a second magnet unit, and the coil may include a first coil unit corresponding to the first magnet unit and a second coil unit corresponding to the second magnet unit.

[0009] The first coil unit may face the first magnet unit in a first horizontal direction perpendicular to the optical axis direction, and the second coil unit may face the second magnet unit in a second horizontal direction perpendicular to the optical axis direction and the first horizontal direction.

[0010] The first coil unit may face the first magnet unit in the optical axis direction, and the second coil unit may face the second magnet unit in the optical axis direction. The lens holder may include at least one groove recessed from an upper surface, and the lens may include at least one protrusion arranged within the at least one groove of the lens holder. The at least one protrusion of the lens may not overlap the tilting guide portion in the optical axis direction.

[0011] The camera device may include a circuit board disposed on the sensor base and on which the image sensor is disposed.

[0012] A camera device according to another embodiment comprises a housing; a moving part including a sensor base disposed within the housing, an image sensor disposed on the sensor base, a lens holder disposed on the image sensor and coupled with the sensor base, and a lens coupled with the lens holder; and a tilting guide disposed between the sensor base and the housing, wherein the lens holder is not movable in the direction of an optical axis with respect to the image sensor, and the moving part tilts with respect to a first axis perpendicular to the direction of the optical axis or a second axis intersecting the direction of the optical axis and the first axis.

[0013] The sensor base may include a plurality of protrusions protruding from the upper surface of the sensor base, and the lens holder may include a plurality of grooves corresponding to the plurality of protrusions in the direction of the optical axis and coupled with the plurality of protrusions.

[0014] A camera device according to another embodiment includes a fixed part; a moving part including a sensor base, an image sensor disposed on the sensor base, and a lens disposed on the image sensor; and a tilting guide disposed between the sensor base and the fixed part, wherein the lens is not movable in the direction of an optical axis with respect to the image sensor, and the moving part tilts with respect to a first axis perpendicular to the direction of the optical axis or a second axis intersecting the direction of the optical axis and the first axis.

[0015] The embodiment can reduce manufacturing costs because it does not include a configuration for autofocus function.

[0016] Since the embodiment does not include a configuration for an autofocus function, the length in the direction of the optical axis of the camera device or the length in the direction perpendicular to the direction of the optical axis of the camera device can be reduced.

[0017] Additionally, in the embodiment, the size of the lens module may not be restricted by the space in which the configuration for the autofocus function is placed.

[0018] In addition, in the embodiment, the size of the lens module and the size of the corresponding image sensor can be increased, thereby enabling the implementation of a high-resolution image.

[0019] The embodiment can reduce the space required for tilting the sensor base, which is an OIS moving part, for image stabilization, and can reduce the size of the camera device.

[0020] In an embodiment, a support member coupled to the moving module may act as a magnetic body that generates a repulsive force to support the OIS moving part.

[0021] The embodiment can reduce the number of parts and reduce the weight of the camera device.

[0022] In addition, since in the embodiment a tilting guide part is used for tilting the OIS moving part, compared to examples that only use a ball member or a shaft member, the OIS moving part can be tilted stably, precisely, and accurately, thereby improving the reliability of OIS operation.

In addition, when it is expressed as "on or under", it can include the meaning of not only the upward direction but also the downward direction based on one element.

[0070] Additionally, relational terms such as “first” and “second,” “upper / upper / lower,” and “lower / lower / below” used hereinafter may be used only to distinguish one entity or element from another entity or element, without necessarily requiring or implying any physical or logical relationship or order between such entities or elements. In addition, the same reference numbers represent the same elements throughout the description of the drawings.

[0071] Furthermore, terms such as "include," "comprise," or "have" described above, unless specifically stated otherwise, imply that the corresponding component may be included, and thus should be interpreted to include other components rather than excluding other components.

The lens holder (110) can include a groove (47) corresponding to the protrusion (216) of the sensor base (270). The protrusion (216) of the sensor base (270) and the groove (47) of the lens holder (110) can serve as a guide for easy assembly of the sensor base (270) and the lens holder (110), and can increase the coupling area to improve the coupling strength between the sensor base (270) and the lens holder (110).

[0100] For example, the groove (47) may be recessed from the lower surface of the lens holder (110). For example, the groove (47) may be positioned or formed in a corner or corner area of ​​the lower surface of the lens holder (110). The groove (47) of the lens holder (110) may have a shape corresponding to the protrusion (216) of the sensor base (270). In addition, the lens holder (110) may include a groove (48) or a hole corresponding to the protrusion (17) of the sensor base (270). For example, the protrusion (17) of the sensor base (270) may be inserted into the groove (48) of the lens holder (110) or may be coupled with the groove (48). For example, the groove (48) may be positioned or formed in the bottom surface of the groove (47) of the lens holder (110). For example, the groove (48) may be recessed from the bottom surface of the groove (47) of the lens holder (110).

[0101] The lens holder (110) and the sensor base (270) can be joined together by an adhesive. The adhesive can be placed in the groove (47) of the lens holder (110) and the protrusion (217) of the sensor base (270).

[0102] In another embodiment, the lens holder (110) may include a protrusion protruding from the lower surface of the lens holder (110) instead of the groove (47), and the sensor base (270) may include a groove that engages with the protrusion of the lens holder (110). In this case, the groove of the sensor base (270) may be recessed from the upper surface of the sensor base (270) instead of the protrusion (217) or may be formed on the upper surface of the protrusion (217). In another embodiment, the protrusion (17) may be formed on the lens holder (110) and the groove (48) may be formed on the sensor base (270).

[0103] The lens holder (110) may not be movable in the optical axis direction relative to the sensor base (270). The lens holder (110) may not be movable in the optical axis direction relative to the circuit board (800) or the image sensor (810). In addition, the lens holder (110) may not be movable in the optical axis direction relative to the fixing member.

[0104] The lens module (400) (or lens) may not be movable in the optical axis direction with respect to the sensor base (270). The lens module (400) (or lens) may not be movable in the optical axis direction with respect to the circuit board (800) or the image sensor (810). In addition, the lens module (400) (or lens) may not be movable in the optical axis direction with respect to the fixing member. In other words, the focus of the lens module (400) (or lens) may not be variable but may be fixed.

[0105] The lens holder (110) may be spaced apart from the cover member (300) for OIS operation. For example, the upper portion (or upper surface) of the lens holder (110) may be spaced apart from the inner surface of the upper plate (301) of the cover member (300), and the side portion (or side surface) of the lens holder (110) may be spaced apart from the inner surface of the side plate (302) of the cover member (300).

[0106] The camera device (200) may include an adhesive (130) that is disposed between the lens holder (110) and the lens module (400) and that couples the lens holder (110) and the lens module (400) to each other. The adhesive (130) may be disposed on the inner surface (or inner circumference) of the lens holder (110) and the outer surface (or outer circumference) of the lens module (400). The adhesive (130) may be attached to or coupled to the inner surface (or inner circumference) of the lens holder (110) and the outer surface (or outer circumference) of the lens module (400).

[0107] The lens module (400) may include at least one of a lens and a lens barrel. When performing image stabilization or shake correction, the lens module (400), the lens holder (110), and the image sensor (810) may simultaneously tilt in the same direction and at the same angle along the first or second axis. The lens module (400) may include a glass lens that exhibits less thermal deformation than a plastic lens. In another embodiment, the lens module (400) may be a plastic lens.

[0108] The lens holder (110) may include at least one groove (21) that is recessed from the upper surface. For example, the lens holder (110) may include a plurality of grooves (21A to 21D) that are spaced apart from each other. The groove (21) may be arranged adjacent to the opening (101). The groove (21) may include an opening that opens to the inner circumferential surface of the lens holder (110). The groove (21) may include a bottom surface (22A) that has a step from the upper surface of the lens holder (110) and a side surface (22B, or side wall) that is arranged between the bottom surface (22A) and the upper surface of the lens holder (110). The bottom surface (22A) may be positioned lower than the upper surface of the lens holder (110). An adhesive may be arranged within the groove (21) of the lens holder (110). For example, the adhesive may be placed on at least one of the bottom surface (22A) and the side surface (22B) of the groove (21) of the lens holder (110). A groove (23) for storing the adhesive (130) and allowing the adhesive to flow may be formed on at least one of the bottom surface (22A) and the side surface (22B) of the groove (21).

[0109] The lens module (400) may include at least one protrusion (24) positioned within the groove (21) of the lens holder (110). For example, the lens (or lens barrel) may include at least one protrusion (24) positioned within the groove (21) of the lens holder (110).

[0110] The protrusion (24) of the lens module (400) can be inserted into the groove (21) of the lens holder (110). The protrusion (24) can protrude from the outer surface of the lens module (400). For example, the protrusion (24) can protrude from the outer surface of the lens module (400) in a direction perpendicular to the optical axis. For example, the protrusion (24) can protrude from the outer surface of the lens barrel (or lens) of the lens module (400).

[0111] At least a portion of the protrusion (24) in the optical axis direction may face or overlap with the groove (21) of the lens holder (110). The protrusion (24) may be disposed on the bottom surface (22B) of the groove (21) of the lens holder (110). The adhesive (130) may be disposed between the protrusion (24) of the lens module (400) and the groove (21) of the lens holder (110). The adhesive (130) may be attached to or coupled to the protrusion (24) of the lens module (400) and the groove (21) of the lens holder (110). The protrusion (24) may include a plurality of protrusions (24A to 24D) spaced apart from each other. The number of the protrusions (24) may be the same as the number of the grooves (21). The protrusion (24) can serve to prevent the lens module (400) from being detached from the lens holder (110) or from rotating due to impact.

[0112] Referring to FIGS. 4d and 4e, the protrusion (24) may not overlap with the tilting guide portion (60) in the optical axis direction. The protrusion (24) may overlap with the coil (230) and the magnet (310) in the optical axis direction. This is because, in the embodiment, a configuration for AF driving is not required, and thus the size of the lens module (400) can be designed to be large. In other embodiments, the protrusion (24) may not overlap with the coil (230) and the magnet (310) in the optical axis direction.

[0113] The lens module (400) and the lens holder (110) are structured to be joined by an adhesive, but in other embodiments, the lens module (400) and the lens holder (110) may be formed as one piece.

[0114] The camera device (200) may include a filter (610) disposed between the lens module (400) and the image sensor (810). The filter (610) may be disposed in the lens holder (110) or coupled with the lens holder (110). For example, the filter (610) may be disposed under the lens holder (110). The filter (610) may be disposed in the lower portion (120) of the lens holder (110). For example, the filter (610) may be disposed on the lower surface of the lower portion (120) of the lens holder (110). For example, the filter (610) may be disposed in the mounting portion (45A) of the lens holder (110).

[0115] The filter (610) can be coupled to the lens holder (110) (or the mounting portion (45A)) by an adhesive (not shown). For example, the edge area of ​​the filter (610) can be coupled to the bottom surface (5A) of the mounting portion (45A). At this time, the adhesive can be epoxy, a thermosetting adhesive, an ultraviolet-curable adhesive, or the like.

[0116] The filter (610) may serve to block light of a specific frequency band from passing through the lens module (400) from entering the image sensor (810). For example, the filter (610) may be an infrared blocking filter. For example, the filter (610) may be arranged parallel to a plane perpendicular to the optical axis (OA). For example, at least a portion of the filter (610) may correspond to, face, or overlap with the lens module (400) or / and the image sensor (810) in the direction of the optical axis.

[0117] The sensor base (270) may be positioned within the cover member (300). The sensor base (270) may be positioned within the housing (210). The sensor base (270) may be positioned beneath the lens holder (110). The sensor base (270) may be positioned beneath the filter (610). For example, the sensor base (270) may be positioned beneath the image sensor (810). For example, the sensor base (270) may be positioned beneath the circuit board (800).

[0118] The sensor base (270) can be combined with the lens holder (110). The sensor base (270) can be expressed as a “holder” instead. In addition, the lens holder (110) can be expressed as a “first housing” (or “first holder”), and the sensor base (270) can be expressed as a “second housing” (or “second holder”). In another embodiment, the sensor base (270) and the lens holder (110) can be formed integrally. The lens holder (110) and the sensor base (270) can be expressed as a single term, for example, a “housing” (or holder), without being expressed separately. Alternatively, in another embodiment, at least two of the sensor base (270), the lens holder (110), and the support member (64) can be formed integrally.

[0119] For example, the sensor base (270) may include a protrusion (216). The protrusion (216) may protrude toward the lens holder (110). The protrusion (216) may protrude from the upper surface of the sensor base (270). The protrusion (216) may also be expressed as a “pillar.”

[0120] For example, the protrusion (216) may correspond to, face, or overlap with the groove (47) of the lens holder (110) in the optical axis direction. At least a portion of the protrusion (216) of the sensor base (270) may be inserted into the groove (47) of the lens holder (110). For example, at least a portion of the protrusion (216) may be coupled with the groove (47) of the lens holder (110). For example, at least a portion of the protrusion (216) may be coupled with the groove (47) of the lens holder (110) by an adhesive.

[0121] For example, the sensor base (270) may include a body (270A) and a protrusion (216) protruding from the upper surface of the body (270A). For example, the body (270A) may have a shape corresponding to the substrate (801) of the circuit board (810). For example, the body (270A) may have a polyhedral shape, for example, a hexahedral shape. For example, the protrusion (216) may be arranged in a corner area of ​​the upper surface of the body (270A). The number of protrusions (216) may be 1 or 2 or more.

[0122] For example, the protrusion (216) may include four protrusions (216A to 216D) arranged at four corner regions of the upper surface of the body (270). Also, for example, the lens holder (110) may include four grooves (47) corresponding to the four protrusions (216A to 216D). In another embodiment, the sensor base (270) may include at least one protrusion arranged at at least one of the four corner regions of the upper surface of the body (270A), and the lens holder (110) may include at least one groove (48) corresponding to at least one protrusion of the sensor base (270).

[0123] The sensor base (270) or body (270A) may include side portions (51A to 51D) that correspond to, oppose, or overlap the side portions (110A to 110D) of the lens holder (110). The sensor base (270) may include a corner positioned between the side portions (51A to 51D). For example, the sensor base (270) may include first to fourth corners.

[0124] The camera device (200) may include a gyro sensor (not shown) disposed on a circuit board (800). For example, the gyro sensor may be disposed on a substrate (801) of the circuit board (800). For example, the gyro sensor may be disposed, coupled, or fixed to a lower surface of the substrate (801). For example, the gyro sensor outputs rotational angular velocity information due to the movement of the camera device (200). For example, the gyro sensor may be implemented as a two-axis or three-axis gyro sensor or an angular velocity sensor. For example, the gyro sensor may be conductively or electrically connected to the substrate (801).

[0125] In another embodiment, the sensor base (270) may include a receiving portion for arranging the gyro sensor or for avoiding spatial interference with the gyro sensor (820). For example, the receiving portion may be a through hole penetrating the sensor base (270) in the direction of the optical axis, or a groove recessed from the upper surface of the sensor base (270) or the upper surface of the body (270A). In this case, the receiving portion may include an opening that opens to the outer surface of the sensor base (270).

[0126] The sensor base (270) may include a receiving portion (255) in which the control portion (830) is placed or for receiving the control portion (830). The receiving portion (255) may be a groove that is recessed from the upper surface of the sensor base (270) or the upper surface of the body (270A). In another embodiment, the receiving portion (255) may be a through hole that passes through the sensor base (270) or the body (270A) in the direction of the optical axis.

[0127] The sensor base (270) may include a mounting portion (274A, 274B) for placing the coil (230). The mounting portion (274A, 274B) may be placed or formed on the upper surface of the sensor base (270). For example, the mounting portion (274A, 274B) may be a groove that is recessed from the upper surface of the sensor base (270). For example, the sensor base (270) may include a first mounting portion (274A) for placing or placing the first coil unit (230A) and a second mounting portion (274B) for placing or placing the second coil unit (230B).

[0128] For example, the first mounting portion (274A) may be formed to be adjacent to or in contact with one of the protrusions (216A to 216D) of the sensor base (270) (e.g., 216C). For example, the first mounting portion (274A) may be a groove formed on the upper surface of the sensor base (270) adjacent to the third protrusion (216C) of the sensor base (270). For example, the first mounting portion (274A) may include an opening that opens from the outer surface of a side (e.g., 51B, 51D) adjacent to the third protrusion (216C) of the sensor base (270). In another embodiment, the first mounting portion (274A) may be spaced apart from the outer surface of the side portion (e.g., 51B, 51D) of the sensor base (270) and may not include an opening that opens to the outer surface of the side portion (51B, 51D).

[0129] For example, the second mounting portion (274B) may be formed to be adjacent to or in contact with another one (e.g., 216D) of the protrusions (216A to 216D) of the sensor base (270). For example, the second mounting portion (274B) may be a groove formed on the upper surface of the sensor base (270) adjacent to the fourth protrusion (216D) of the sensor base (270). For example, the second mounting portion (274B) may include an opening that opens from the outer surface of a side (e.g., 51B, 51C) adjacent to the fourth protrusion (216D) of the sensor base (270). In another embodiment, the second mounting portion (274B) may be spaced apart from the outer surface of the side portion (e.g., 51B, 51C) of the sensor base (270) and may not include an opening that opens to the outer surface of the side portion (51B, 51C).

[0130] In another embodiment, the mounting portion (274) of the sensor base (270) may be formed at a position corresponding to the position where the coil (230) is placed.

[0131] In another embodiment, the mounting portions (274A, 274B) may be in the form of through holes. For example, at least one of the first and second mounting portions (274A, 274B) may be a hole or through hole penetrating the sensor base (270) in the optical axis direction. In this case, a part of the sensor base (270) may not be interposed between the coil (230) and the magnet (310), and thus, the electromagnetic force between the magnet (310) and the coil (230) may increase. In addition, since a part of the sensor base (270) may not be interposed between the position sensor (240) and the magnet (310), the output of the position sensor (240) may be increased, and the sensitivity of the position sensor (240) may be improved. In addition, since a part of the sensor base (270) is not interposed between the position sensor (240) and the magnet (310), the height of the camera device may be reduced. In another embodiment, the anchoring portion (274A, 274B) may be in the form of an escape portion that avoids spatial interference with the entire coil (230).

[0132] The sensor base (270) may include a groove (29) in which at least a portion (e.g., a protrusion (65)) of the tilting guide portion (60) is arranged or received. The groove (29) may be formed on the lower surface of the sensor base (270). For example, the groove (29) may be recessed from the lower surface of the sensor base (270). The number of grooves (29) may be the same as the number of protrusions (65) of the tilting guide portion (60). For example, the groove (29) may include two grooves (29A, 29B) that are spaced apart from each other. For example, the two grooves (29A, 29B) may be arranged to be spaced apart from each other in the first axis direction (see FIG. 16A). For example, the extension (217) of the sensor base (270) can be placed between two grooves (29A, 29B) of the sensor base (270).

[0133] The groove (29) can contact the protrusion (65) of the tilting guide part (60) at at least one point. For example, the groove (29) can include a bottom surface and at least one side surface connected to the bottom surface. At least one side surface can be an inclined surface. For example, the groove (29) can include a bottom surface and a plurality of inclined surfaces. The shapes of the inclined surfaces of the groove (29) can be the same as each other. In another embodiment, at least one of the inclined surfaces of the groove (29) can have a different shape from the others.

[0134] Referring to FIG. 7A, a groove (212A) may be formed in the protrusion (216) of the sensor base (270) into which at least a portion of the substrate (801) of the circuit board (800) is inserted or placed. For example, a corner of the substrate (801) may be inserted into or coupled with the groove (212A) of the protrusion (216) of the sensor base (270). For example, the groove (212A) may be formed on a side of the protrusion (216) facing the corner of the circuit board (800). In addition, a groove (83) may be formed in at least one corner of the circuit board (800) to be inserted into or coupled with the groove (212A) of the protrusion (216). The groove (212A) of the protrusion (216) of the sensor base (270) can serve as a defect guide for combining the substrate (801) and the sensor base (270), and can serve to prevent the substrate (801) from rotating or being separated from the sensor base (270).

[0135] The circuit board (800) may be placed under the lens holder (110). The circuit board (800) may be placed under the lens module (400).

For example, the substrate (801) may be placed, coupled, or fixed to the body (270A) of the sensor base (270). For example, a lower surface of the substrate (801) may be coupled to an upper surface of the sensor base (270) or an upper surface of the body (270A). For example, a lower surface of the substrate (801) may be coupled to an upper surface of the sensor base (270) or an upper surface of the body (270A) by an adhesive.

[0138] The circuit board (800) may include a substrate (803) on which a connector (805) is arranged or provided, and a substrate (804) connecting the substrate (801) and the substrate (803).

[0139] For example, a rigid printed circuit board may include a plurality of conductive layers (or circuit patterns) spaced apart from each other in the optical axis direction and an insulating layer disposed between two adjacent conductive layers among the plurality of conductive layers. For example, a flexible circuit board may include one conductive layer (or circuit pattern), a first insulating layer disposed on the conductive layer, and a second insulating layer disposed under the conductive layer. In another embodiment, the flexible circuit board may include a first conductive layer, a second conductive layer, and a first insulating layer disposed between the first and second conductive layers, a second insulating layer disposed on the first conductive layer, and a third insulating layer disposed under the second conductive layer.

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

[0144] The camera device (200) may include a control unit (830) disposed on a circuit board (800). For example, the control unit (830) may be a driver IC.

In addition, the control unit (830) can be conductively or electrically connected to the position sensor (240).

[0146] The control unit (830) can receive an output signal of the position sensor (240) and control a driving signal (e.g., driving current) supplied to the coil (230) using the output signal of the position sensor (240). For example, the control unit (830) can receive an output signal of the first sensor (240A) and control a first driving signal (e.g., first driving current) supplied to the first coil unit (230A) using the output signal of the first sensor (240A). In addition, the control unit (830) can receive an output signal of the second sensor (240B) and control a second driving signal (e.g., second driving current) supplied to the second coil unit (230B) using the output signal of the second sensor (240B).

For example, the first coil unit (230A) and the second coil unit (230B) may be disposed between the substrate (801) and the sensor base (270).

[0149] For example, the first and second coil units (230A, 230B) may be positioned adjacent to two adjacent corners among the four corners of the substrate (801). For example, for diagonal driving, the first coil unit (230A) may be positioned adjacent to one corner of the substrate (801) corresponding to the protrusion (216C) of the sensor base (270) (or any corner of the sensor base (270)), and the second coil unit (230B) may be positioned adjacent to the other corner of the substrate (801) corresponding to the protrusion (216D) of the sensor base (270) (or any other corner of the sensor base (270). For example, the first coil unit (230A) may be positioned adjacent to the protrusion (216C) of the sensor base (270), and the second coil unit (230B) may be positioned adjacent to the protrusion (216D) of the sensor base (270).

[0150] The coil (230) can tilt the OIS moving part (100) or rotate it by a preset angle about the first or second axis by interaction with the magnet (310) placed in the housing (210), which is a fixed part.

[0151] The coil (230) may be opposite, opposite, or overlapping with the magnet (310) in the direction of the optical axis. The coil (230) may include a first coil unit (230A) opposite, opposite, or overlapping with the first magnet unit (310A) in the direction of the optical axis, and a second coil unit (230B) opposite, opposite, or overlapping with the second magnet unit (310B) in the direction of the optical axis. For example, the coil (230) may not overlap with the magnet (310) in a direction perpendicular to the optical axis.

[0152] The coil (230) may be placed between the circuit board and the sensor base (270). The first coil unit (230A) may be placed within the first mounting portion (274A) of the sensor base (270), and the second coil unit (230B) may be placed within the second mounting portion (274B) of the sensor base (270).

[0153] For example, each of the first and second coil units (230A, 230B) may include a hollow or a hole. For example, each of the first and second coil units (230A, 230B) may have a ring shape or a closed curve shape. For example, each of the first coil unit (230A) and the second coil unit (230B) may have a ring shape that is wound around a straight line that is parallel to the optical axis (OA) and perpendicular to the upper surface of the sensor base (270) or the upper surface of the body (270A).

[0154] For example, referring to FIG. 16A, the first coil unit (230A) may be a ring shape in which the length in the horizontal direction (or the direction parallel to the second axis) is longer than the length in the vertical direction (or the direction parallel to the first axis). For example, the second coil unit (230B) may be a ring shape in which the length in the vertical direction (e.g., the direction parallel to the first axis) is longer than the length in the horizontal direction (or the direction parallel to the second axis).

[0155] For OIS feedback operation, the camera device (200) may include a position sensor (240). The position sensor (240) may detect displacement or angular displacement of the OIS moving unit (100) according to tilting or rotation of the OIS moving unit (100). The position sensor (240) may detect a magnetic field of a magnet (310).

[0156] For example, the position sensor (240) may include a first sensor (240A) and a second sensor (240B). For example, at least a portion of the first sensor (240A) may correspond to, face, or overlap the first magnet unit (310A) in the optical axis direction. For example, the center of the first sensor (240A) may overlap the first magnet unit (310A) in the optical axis direction. For example, the first sensor (240A) may detect the first magnet unit (310A) (or the magnetic field of the first magnet unit (310A)). For example, the first sensor (240A) may detect a tilting angle with respect to the second axis of the OIS moving unit (100). In another embodiment, the first sensor (240A) may not overlap the first and second magnet units (310A, 310B) in the optical axis direction.

[0157] At least a portion of the second sensor (240B) may correspond to, face, or overlap the second magnet unit (310B) in the optical axis direction. For example, the center of the second sensor (240B) may overlap the second magnet unit (310B) in the optical axis direction. For example, the second sensor (240B) may detect the second magnet unit (310B) (or the magnetic field of the second magnet unit (310B)). For example, the second sensor (240A) may detect the angle at which the OIS moving part (100) is tilted with respect to the first axis. In other embodiments, the second sensor (240B) may not overlap the second magnet unit (310B) in the optical axis direction.

[0158] For example, the first and second sensors (240A, 240B) may be placed, coupled, or fixed to the substrate (801) of the circuit board (800). For example, the first and second sensors (240A, 240B) may be conductively or electrically connected to the substrate (801) of the circuit board (800).

[0159] For example, the first sensor (240A) may be placed within the hollow (or hole) of the first coil unit (230A), and the second sensor (240B) may be placed within the hollow (or hole) of the second coil unit (230B). In another embodiment, the first sensor (240A) may be placed outside the hollow (or hole) of the first coil unit (230A), and the second sensor (240B) may be placed outside the hollow (or hole) of the second coil unit (230B).

[0160] For example, the first sensor (240A) and the second sensor (240B) may each be a Hall sensor including first and second input terminals and first and second output terminals. For example, the first and second input terminals and the first and second output terminals of the first sensor (240A) may be conductively or electrically connected to the substrate (801), and the first and second input terminals and the first and second output terminals of the second sensor (240B) may be conductively or electrically connected to the substrate (801).

[0161] For example, the substrate (801) or the control unit (830) can supply or apply a first driving signal to the first and second input terminals of the first sensor (240A). The first sensor (240A) can output a first output signal, and the first output signal can be transmitted to the substrate (801) or the control unit (830). The first output signal can be output to the first and second output terminals of the first sensor (240A).

[0162] For example, the substrate (801) or the control unit (830) can supply or apply a second drive signal to the first and second input terminals of the second sensor (240B). The second sensor (240B) can output a second output signal, and the second output signal can be transmitted to the substrate (801) or the control unit (830). The second output signal can be output to the first and second output terminals of the second sensor (240B).

[0163] The control unit (830) can control the first driving signal supplied to the first coil unit (230A) and the second driving signal supplied to the second coil unit (230B) using the first output signal of the first sensor (240A) and the output signal of the second sensor (240B).

[0164] In another embodiment, each of the first sensor (240A) and the second sensor (240B) may be a driver IC including a Hall sensor.

[0165] When each of the first and second sensors (240A, 240B) is a driver IC, the position sensor (240) can transmit and receive data with another element (e.g., the control unit (780)) using data communication using a protocol, for example, I2C communication. At this time, each of the first and second sensors (240A, 240B) may include first and second terminals for inputting a power or driving signal, a third terminal for a clock signal, a fourth terminal for a data signal, and fifth and sixth terminals for supplying a driving signal to the coil units (230A, 230B). The first to sixth terminals of each of the first and second sensors (240A, 240B) may be conductively or electrically connected to the circuit board (800). The fifth and sixth terminals of the first sensor (240A) can be electrically connected to the first coil unit (230A), and the fifth and sixth terminals of the second sensor (240B) can be electrically connected to the second coil unit (230B).

[0166] The first sensor (240A) can supply a first driving signal to the first coil unit (230A) through the fifth and sixth terminals of the first sensor (240A), and the second sensor (240B) can supply a second driving signal to the second coil unit (230B) through the fifth and sixth terminals of the second sensor (240B). The first sensor (240A) can supply a first driving signal to the first coil unit (230A) through the circuit board (800), and the second sensor (240B) can supply a second driving signal to the second coil unit (230B) through the circuit board (800).

[0167] The camera device (200) may include a heat dissipation member (not shown) coupled to at least one of the circuit board (800) or the sensor base (270). For example, the heat dissipation member may be disposed under the circuit board (800). For example, the heat dissipation member (280) may be disposed between the circuit board (800) and the sensor base (270). The heat dissipation member may be a plate-shaped member having a preset thickness and hardness. In addition, the heat dissipation member may dissipate heat generated from a heat source of the circuit board (800) to the outside and improve heat dissipation efficiency. For example, the heat dissipation member may be a metal material or a metal plate.

[0168] Referring to FIGS. 10A and 10B, the housing (210) may include a cavity for accommodating the OIS moving part (100). At least a portion (e.g., an upper portion) of the housing (210) may be disposed within the cover member (300).

[0169] For example, the housing (210) may have a shape corresponding to the OIS moving part (100), for example, the lens holder (110) or the sensor base (270), for example, a polygon (for example, a square or an octagon) or a circle (or an oval), but is not limited thereto and may have various shapes. The housing (210) may be expressed as a “base” or a “frame”.

[0170] The housing (210) may include a plurality of side portions (71A to 71D) corresponding to the side portions (110A to 110D) of the lens holder (110) or the side portions (51A to 51D) of the sensor base (270). The housing (210) may include a corner positioned between two adjacent side portions. In addition, the housing (210) may include a lower portion (42) (or lower plate) positioned below the side portions (71A to 71D). The lower portion (42) of the housing (210) may be connected to the lower sides of the side portions (71A to 71D). For example, the lower portion (42) may be expressed as a “bottom portion,” a “bottom surface,” or a “body.” For example, the side portions (71A to 71D) may protrude upward from the lower portion (42).

[0171] The housing (210) may include a first side (71A) corresponding to, opposite to, or overlapping a first side (110A) of the lens holder (110), a second side (71B) corresponding to, opposite to, or overlapping a second side (110B) of the lens holder (110), a third side (71C) corresponding to, opposite to, or overlapping a third side (110C) of the lens holder (110), and a fourth side (71D) corresponding to, opposite to, or overlapping a fourth side (110D) of the lens holder (110).

[0172] The first side (71A) (or the first side or the first outer surface) of the housing (210) may be positioned opposite the second side (71B) (or the second side or the second outer surface) of the housing (210), and the third side (71C) (or the third side or the third outer surface) of the housing (210) may be positioned opposite the fourth side (71D) (or the fourth side or the fourth outer surface) of the housing (210). For example, each of the first to fourth sides (71A to 71D) of the housing (210) may be positioned parallel to a corresponding one of the side plates (302) of the cover member (300).

[0173] The housing (210) may include a step (411) disposed on the lower portion of at least one of the sides (71A to 71D). For example, the step (411) may protrude in a direction perpendicular to the optical axis from the outer surface of the side (71A to 71D) of the housing (210). For example, the step (411) may face or overlap with the side plate (302) of the cover member (300) in the direction of the optical axis. For example, the step (411) may be coupled to the side plate (302) of the cover member (300) by an adhesive.

[0174] The housing (210) may include a mounting portion (141A, 141B) for placing a magnet (310). For example, the mounting portion (141A, 141B) may be a groove-shaped portion formed in the lower portion (42) of the housing (210). In another embodiment, the mounting portion (141A, 141B) may be a through hole penetrating the lower portion (42) of the housing (210). The housing (210) may include a first mounting portion (141A) for placing a first magnet unit (310A) and a second mounting portion (141B) for placing a second magnet unit (310B).

[0175] For example, the first mounting portion (141A) may be positioned or formed in a first region of the lower portion (42) of the housing (210) adjacent to any one of the four corners of the housing (210). For example, the one corner of the housing (210) may be a corner corresponding to or adjacent to a protrusion (216C) of the sensor base (270). For example, the second mounting portion (141B) may be positioned or formed in a second region of the lower portion (42) of the housing (210) adjacent to any other of the four corners of the housing (210). For example, the one other corner of the housing (210) may be a corner corresponding to or adjacent to a protrusion (216D) of the sensor base (270).

[0176] In another embodiment, the first and second mounting portions may be positioned at positions corresponding to the positions where the coil units (230A, 230B) and the magnet units (310A, 310B) are positioned. For example, in another embodiment, the first mounting portion may be formed adjacent to the first side (or second side) of the housing (210), and the second mounting portion may be formed adjacent to the third side (or fourth side) of the housing (210).

[0177] The magnet (310) can be placed in the housing (210). The magnet (310) can be coupled to the housing (210). The magnet (310) can be placed in the lower portion (42) of the housing (210). For example, the magnet (310) can include a first magnet unit (310A) and a second magnet unit (310B) that are spaced apart from each other.

[0178] For example, the magnet (310) may be placed under the coil (230). The magnet (310) may face or overlap the coil (230) in the optical axis direction. For example, the first magnet unit (310A) may be placed to correspond to, face, or overlap the first coil unit (230A) in the optical axis direction. The second magnet unit (310B) may be placed to correspond to, face, or overlap the second coil unit (230B) in the optical axis direction.

[0179] For example, the first magnet unit (310A) and the second magnet unit (310B) may be arranged to be misaligned in the first axis direction (or in the direction parallel to the first axis) or in the second axis direction (or in the direction parallel to the second axis). For example, when viewed from above or in the optical axis direction, the first magnet unit (310A) and the second magnet unit (310B) may be arranged in the housing (210) so as not to overlap each other in the direction parallel to the first axis or in the direction parallel to the second axis. For example, the first magnet unit (310A) and the second magnet unit (310B) may be arranged in the lower portion (42) of the housing (210) so as not to overlap each other in the direction parallel to the first axis or in the direction parallel to the second axis.

[0180] Each of the first magnet unit (310A) and the second magnet unit (310B) may be a two-pole magnet including one N pole and one S pole. For example, each of the first magnet unit (310A) and the second magnet unit (310B) may be a magnet that is divided or arranged into an N pole and a S pole in the optical axis direction. For example, the N pole (or S pole) of each of the first magnet unit (310A) and the second magnet unit (310B) may be located above the S pole (or N pole).

[0181] For example, the first surface of the magnet (310) facing or opposing the coil (230) in the direction of the optical axis may be a south pole (or north pole). And the second surface, which is the opposite surface of the first surface of the magnet (310), may be a north pole (or south pole).

[0182] In another embodiment, the magnet (310) may include three or more magnet units. For example, the magnet (310) may include a first magnet unit (310A), a second magnet unit (310B), and a third magnet unit disposed opposite the first magnet unit (310A) with respect to the optical axis. In yet another embodiment, the magnet (310) may include a first magnet unit (310A), a second magnet unit (310B), a third magnet unit disposed opposite the first magnet unit (310A) with respect to the optical axis, and a fourth magnet unit disposed opposite the second magnet unit (310B) with respect to the optical axis.

[0183] In another embodiment, the magnet (310) may be a four-pole magnet to enhance the electromagnetic force. For example, the magnet (310) may include two N poles and two S poles. For example, the magnet (310) may include a first magnet including a N pole and a S pole, a second magnet including a S pole and an N pole, and a partition wall disposed between the first magnet and the second magnet. In this case, the partition wall may include a substantially non-magnetic portion with a section having almost no polarity, may be filled with air or made of a non-magnetic material, and may be expressed as a "neutral zone." For example, the first magnet and the second magnet may face each other in the optical axis direction, and the first magnet and the second magnet may be disposed to face each other with different polarities in the optical axis direction. The number of corresponding magnet units and coil units of the OIS driving unit may be 2, 3, or 4, but in other embodiments may be 5 or more.

[0184] Referring to FIGS. 10A and 16A, the camera device (200) may include a yoke (380) disposed on a magnet (310). The yoke (380) may reduce or suppress leakage flux of the magnet (310), increase the electromagnetic force between the magnet (310) and the coil (230), and enhance the driving force for OIS operation. The yoke (380) may be made of a material that is attracted to a magnet. For example, the yoke (380) may be made of a metal material. Alternatively, the yoke (380) may be made of a magnetic metal material. Alternatively, the yoke (380) may be a magnetic body, for example, a magnet.

[0185] The yoke (380) may be disposed in the housing (210). For example, the yoke (380) may be disposed between the housing (210) and the magnet (310). For example, the yoke (380) may be disposed within the mounting portion (141A, 141B) of the housing (210). For example, the yoke (380) may face the magnet (310) or the coil (230). For example, the yoke (380) may be disposed on a second surface (e.g., a lower surface) of the magnet (310) that is located opposite a first surface (e.g., an upper surface) of the magnet (310) that faces the coil (230). The yoke (380) may be in contact with or attached to the magnet (310). For example, the yoke (380) may be attached to the magnet (310).

[0186] For example, the yoke (380) may be coupled to the housing (210) by an insert injection molding method. When the yoke (380) and the housing (210) are coupled by an insert injection molding method, at least a portion of the yoke (380) is located inside the housing (210) and at least another portion of the yoke (380) is exposed from the housing (210) and may be coupled or attached to the magnet (310).

[0187] In another embodiment, the yoke (380) may be positioned within the mounting portions (141A, 141B) of the housing (210) by an adhesive. The yoke (380) may include a first yoke (380A) positioned within the first magnet unit (310A) and a second yoke (380B) positioned within the second magnet unit (310B). For example, the first yoke (380A) may be positioned within the first mounting portion (141A) of the housing (210), and the second yoke (380B) may be positioned within the second mounting portion (141B) of the housing (210). Since the magnet (310) can be attached to the yoke (380), when assembling the magnet (310) to the housing (210), the assembling ability between the magnet (310) and the housing (210) can be improved or the assembling between the magnet (310) and the housing (210) can be made easy.

[0188] In another embodiment, each of the first magnet unit (310A) and the second magnet unit (310B) may be a magnet that is divided or arranged into one N pole and one S pole in a direction perpendicular to the optical axis direction. In another embodiment, each of the first magnet unit (310A) and the second magnet unit (310B) may be a magnet including two N poles and two S poles. An electromagnetic force may be generated between the first and second magnet units (310A, 310B) and the first and second coil units (230A, 230B), and the OIS moving part may tilt in the first axis or the second axis by the generated electromagnetic force.

[0189] The housing (210) may include a receiving portion (49A) for receiving or placing a magnetic body (31). The receiving portion (49A) may be placed or formed in the lower portion (42) of the housing (210). The receiving portion (49A) may be placed or formed on the upper surface of the lower portion (42) of the housing (210). For example, the receiving portion (49A) may be a groove that is recessed from the upper surface of the lower portion (42) of the housing (210). The receiving portion (49A) may have a shape corresponding to the magnetic body (31), for example, a square or a circle. For example, the receiving portion (49A) of the housing (210) may correspond to, face, or overlap with the support member (64) or the magnetic body (33) in the optical axis direction.

[0190] Referring to FIG. 10B, the housing (210) may include a seating portion (69) in which at least a portion of the tilting guide portion (60) is disposed or for accommodating at least a portion of the tilting guide portion (60). For example, the seating portion (69) may be a groove that is recessed from the bottom surface or the upper surface of the lower portion (42) of the housing (210). For example, the seating portion (69) may have a shape corresponding to or identical with the tilting guide portion (60). For example, the seating portion (69) may include a bottom surface (69A) that has a step from the upper surface of the lower portion (42) of the housing (210) in the optical axis direction, and a side surface (69B) that connects the bottom surface (69A) and the upper surface of the lower portion (42). The side surface (69B) may also be expressed as a “partition wall” or a “side wall.” For example, the bottom surface (69A) of the mounting portion (69) may be positioned lower than the upper surface of the lower portion (42) of the housing (210). In other embodiments, the mounting portion (69) may be omitted.

[0191] Referring to FIGS. 4A, 4B, 11, and 12, since a mounting portion (69) for inserting or placing at least a portion of the tilting guide portion (60) is formed on the upper surface of the lower portion (42) of the housing (210), the lower portion (42) of the housing (210) may include a partition wall (69B) (or guide portion) arranged around the tilting guide portion (60). The tilting guide portion (60) may be spaced apart from the partition wall (69B) of the housing (210), and the partition wall (69B) may be arranged to surround the tilting guide portion (60). The tilting guide portion (60) may be prevented from being separated or detached from the housing (210) by the partition wall (272) of the housing (210). In another embodiment, at least a portion of the tilting guide portion (60) may be in contact with the bulkhead (69B) of the housing (210).

[0192] The housing (210) may include a portion (or “first portion (49)”) disposed between the magnetic body (31) and the magnetic body (33). For example, the housing (210) may include a coupling portion (49) coupled to the magnetic body (31). The coupling portion (49) may be disposed between the magnetic body (31) and the magnetic body (33).

[0193] For example, the coupling portion (49) may be a part of the lower portion (42) of the housing (210). For example, the coupling portion (49) may be a projection or a protrusion protruding from the lower portion (42) of the housing (210). For example, the coupling portion (49) may protrude from the upper surface of the lower portion (42) of the housing (210). Or, for example, the coupling portion (49) may protrude from the bottom surface (69A) of the mounting portion (69) of the housing (210). For example, the protruding length of the coupling portion (49) of the housing (210) may be greater than the depth of the mounting portion (69) of the housing (210). For example, the protruding length of the coupling portion (49) may be the distance (or the shortest distance) from the bottom surface (69A) of the mounting portion (69) to the upper surface (or top) of the coupling portion (49). Additionally, the depth of the mounting portion (69) may be the distance (or shortest distance) from the upper surface of the lower portion (42) of the housing (210) to the bottom surface (69A) of the mounting portion (69). In another embodiment, for example, the protruding length of the coupling portion (49) may be smaller than or equal to the depth of the mounting portion (69). For example, the coupling portion (49) may have a shape corresponding to or coinciding with the opening (60A) of the tilting guide portion (60).

[0194] For example, the coupling portion (49) of the housing (210) may correspond to, face, or overlap with the opening (60A) of the tilting guide portion (60) in the optical axis direction. For example, at least a portion of the coupling portion (49) of the housing (210) may be disposed within the opening (60A) of the tilting guide portion (60). Since at least a portion of the coupling portion (49) of the housing (210) is disposed within the opening (60A) of the tilting guide portion (60), the separation distance between the coupling portion (49) and the magnetic body (33) can be reduced, and thus the repulsive force between the magnetic body (31) disposed at the coupling portion (49) and the magnetic body (33) disposed at the OIS moving portion can be increased, thereby stably supporting the OIS moving portion.

[0195] For example, the receiving portion (49A) may be positioned or formed in the joining portion (49) of the housing (210). For example, the receiving portion (49A) may be a groove that is recessed from the upper surface of the joining portion (49) of the housing (210).

[0196] For example, when viewed in the direction of the optical axis or when viewed from above, the coupling portion (49) may be positioned between the grooves (55A, 55B) of the housing (210). For example, the coupling portion (49) may be positioned between the protrusions (66A, 66B) of the tilting guide portion (60). For example, the coupling portion (49) (or the magnetic body (31)) may overlap the protrusions (66A, 66B) of the tilting guide portion (60) in a direction perpendicular to the optical axis.

[0197] For example, at least a portion of the first magnet unit (310A) may correspond to, face against, or overlap with the tilting guide portion (60) in a direction parallel to the first axis. In addition, at least a portion of the second magnet unit (310B) may correspond to, face against, or overlap with the tilting guide portion (60) in a direction parallel to the second axis.

[0198] The housing (210) may include a groove (55) in which at least a portion of the protrusion (66) of the tilting guide portion (60) is disposed or for receiving at least a portion of the protrusion (66). The groove (55) of the housing (210) may be formed on an upper surface of the lower portion (42) of the housing (210). For example, the groove (55) may be recessed from an upper surface of the lower portion (42) of the housing (210). For example, the groove (55) may be formed on a bottom surface (69A) of a seating portion (69) of the housing (210). For example, the groove (55) may be recessed from a bottom surface (69A) of the seating portion (69) of the housing (210). The number of grooves (55) of the housing (210) may be the same as the number of protrusions (66) of the tilting guide portion (60).

[0199] For example, the home (55) may include two grooves (55A, 55B) that are spaced apart from each other. For example, the two grooves (55A, 55B) may be arranged to be spaced apart from each other in the second axial direction. For example, the direction in which the two grooves (55A, 55B) of the housing (210) are spaced apart and the direction in which the two grooves (29A, 29B) of the sensor base (270) are spaced apart may intersect or be perpendicular to each other. For example, the receiving portion (49A) may be arranged between the two grooves (55A, 55B) of the housing (210).

[0200] The groove (55) of the housing (210) may contact the protrusion (66) of the tilting guide portion (60) at at least one point. For example, the groove (55) may include a bottom surface and at least one side surface connected to the bottom surface. At least one side surface of the groove (55) may be an inclined surface. For example, the groove (55) may include a bottom surface and a plurality of inclined surfaces. The shapes of the inclined surfaces of the groove (55) may be the same as each other. In another embodiment, at least one of the inclined surfaces of the groove (55) may have a different shape from the others.

[0201] The housing (210) may include an opening (18) or “home” for placing or passing through at least a portion of the moving module (or tilting module). For example, the housing (210) may include an opening (18) for placing or passing through at least a portion of the sensor base (270). The opening (18) may be formed in the lower portion (42) of the fixed portion (e.g., the housing (210)). The opening (18) may be a hole or hollow portion penetrating the lower portion (42) of the housing (210).

[0202] Referring to FIG. 13, the fixed part (e.g., housing (210)) may include a groove (89) formed on the lower surface of the lower surface (42) of the fixed part (housing (210)). The groove (89) may be recessed from the lower surface of the lower surface (42) of the housing (210). For example, the groove (89) may include a bottom surface (89A) and a side surface (89B) positioned between the bottom surface (89A) and the lower surface of the lower surface (42). For example, the bottom surface (89A) may be the lower surface of the coupling part (49). For example, the opening (18) may be formed on the bottom surface (89A) of the groove (89). At least a portion of the support member (64) may be disposed within the groove (89) of the housing (210).

[0203] Referring to FIGS. 4d and 4e, the end of the extension (217) of the sensor base (270) may be positioned higher than the lower surface of the lower surface (42) of the housing (210). In addition, the lower surface of the support member (64) may be positioned higher than the lower surface of the lower surface (42) of the housing (210).

[0204] In order for the support member (64) to be placed in the groove (89), when viewed from below, the size of the groove (89) may be larger than the size of the support member (64). Alternatively, the area of ​​the upper surface of the support member (64) may be smaller than the total area of ​​the opening (18) of the fixed part (housing (210)). In other embodiments, the groove (89) may be omitted.

[0205] The opening (18) may include a through hole penetrating the housing (210) in the direction of the optical axis. For example, the opening (18) may include a hole or a through hole penetrating the lower portion (42) of the housing (210). For example, the opening (18) may be arranged within the mounting portion (69). For example, the opening (18) may be formed in the bottom surface (69A) of the mounting portion (69). The opening (18) may include a hole penetrating the bottom surface (69A) of the mounting portion (69). For example, the opening (18) may open to the lower surface of the lower portion (42) of the housing (210). For example, the opening (18) may include a first opening (18A) and a second opening (18B).

[0206] For example, when viewed from the top, it may include a first opening (18A) (or first hole) located on one side (e.g., the right side (or upper side)) of the connecting portion (49) and a second opening (18B) (or second hole) located on the other side (e.g., the left side (or lower side)) of the connecting portion (49).

[0207] In the embodiments of FIGS. 4B, 10A, and 10B, the first opening (18A) and the second opening (18B) are connected to each other, but in other embodiments, the first opening and the second opening may be separated from each other or spaced apart from each other with the coupling portion (49) therebetween. The shapes of the first opening (18A) and the second opening (18B) may correspond to or be identical to the shape of the extension portion (217) of the sensor base (270). The opening (18) of the housing (210) may serve as an assembly passage for coupling the support member (64) with the extension portion (217) of the sensor base (270). Therefore, the size of the opening (18), for example, the diameter, may be larger than the size of the support member (64). In this case, the size of the support member (64) may be the length of the support member (64) in a direction perpendicular to the optical axis (length in the horizontal or vertical direction).

[0208] The moving module (or tilting module) may be positioned within the opening (18) of the housing (210) or may include at least a portion (or “extension”) passing through the opening (18) of the housing (210). At least a portion (or extension) of the moving module (or tilting module) may be connected or coupled to the magnetic body (33). For example, at least a portion (or extension) of the moving module (or tilting module) may be connected or coupled to the support member (64).

[0209] Referring to FIG. 7d, for example, the sensor base (270) may be disposed within the opening (18) of the housing (210) or may include at least a portion (or “extension”) (217) that passes through the opening (18) of the housing (210). The extension (217) of the sensor base (270) may extend or protrude from the lower or bottom surface of the sensor base (270). The extension (217) may also be alternatively expressed as a “protrusion,” a “guide,” a “coupling guide,” or a “coupling.”

[0210] The extension (217) may be connected or coupled with the magnetic body (33). For example, the connection (217) may be connected or coupled with the support member (64). For example, the sensor base (217) may include at least one protrusion (219) for coupling with the support member (64), and the support member (64) may include at least one groove (8), hole, or through-hole for coupling with the protrusion (219) of the sensor base (270). For example, the groove (8) may be formed on the upper surface of the support member (64).

[0211] The sensor base (270) may include two protrusions (219A, 219B), but in other embodiments, the number of protrusions of the sensor base (270) may be one or three or more. The groove (8) of the support member (64) may include two grooves (8A, 8B), but in other embodiments, the number of grooves (8) of the support member (64) may be the same as the number of protrusions of the sensor base (270). In yet other embodiments, the extension (217) of the sensor base (270) may include a protrusion, and the support member (64) may include a groove, hole, or aperture that corresponds to or engages with the protrusions of the extension (217).

[0212] At least a portion of the extension (217) may be disposed within the opening (18) of the housing (210). At least a portion of the extension (217) may be exposed from the opening (18) of the housing (210). For example, the extension (217) may include a first extension (217A) corresponding to, opposite, or overlapping a first opening (18A) of the housing (210) and a second extension (217B) corresponding to, opposite, or overlapping a second opening (18B) of the housing (210). For example, at least a portion of the first extension (217A) may be disposed within or pass through the first opening (18A) of the housing (210). For example, at least a portion of the second extension (217B) may be disposed within or pass through the second opening (18B) of the housing (210).

[0213] At least a portion of the extension portion (217) may be arranged to surround at least a portion of the protrusions (219A, 219B). For example, at least a portion of the extension portion (217) may include a guide portion (9A, 9B) that surrounds at least a portion of the protrusions (219A, 219B). For example, a first extension portion (217A) may include a first guide portion (9A) that surrounds at least a portion of the first protrusion (219A). A second extension portion (217B) may include a second guide portion (9B) that surrounds at least a portion of the second protrusion (219B). For example, the guide portions (9A, 9B) may be arranged to surround at least a portion of the support member (64). For example, the first guide portion (9A) may be arranged to surround a portion of the support member (64), and the second guide portion (9B) may be arranged to surround another portion of the support member (64). The guide portion (9A, 9B) can guide the coupling of the support member (64) and the extension portion (217) of the sensor base (270). In another embodiment, the extension portion (217) may include a groove for placing or settling at least a portion of the support member (64).

[0214] The housing (210) may include a protrusion (215) that protrudes in a direction perpendicular to the optical axis. For example, the protrusion (215) may protrude from a side of the housing (210). For example, the protrusion (215) may protrude from an outer surface of the fourth side (71D) of the housing (210). For example, the protrusion (215) may be in a form in which at least a portion of the fourth side (71D) passes the optical axis and protrudes in a direction parallel to a straight line perpendicular to the optical axis. For example, the protrusion (215) may include a groove (16A) (or cavity) for placing or receiving at least a portion of the substrate (804). For example, the groove (16A) of the protrusion (215) may include an opening that opens upward.

[0215] Referring to Fig. 10a, a coupling groove (215A, 215B) may be formed in the groove (16A) of the protrusion (215) to allow the movement-inhibiting member (80) to be inserted, coupled, or fixed. For example, the coupling grooves (215A, 215B) may be formed on two inner surfaces facing each other of the groove (16A) of the protrusion (215). For example, the coupling grooves (215A, 215B) may extend in the optical axis direction. For example, the coupling grooves (215A, 215B) may include an opening that opens to the upper surface of the protrusion (215) to easily insert or couple the movement-inhibiting member (80) from above.

[0216] The maximum length of the protrusion (215) in the optical axis direction may be smaller than the maximum length of the housing (210) in the optical axis direction. By this configuration, a space for the circuit board (800) to extend outward can be easily secured, and a compact camera device can be implemented.

[0217] The camera device (200) may include a movement restraining member (80) coupled with at least a portion of the housing (210). The movement restraining member (800) may restrain movement or motion of at least a portion of the substrate (804) to prevent deformation of the shape of at least a portion of the substrate (804).

[0218] Referring to FIGS. 7C, 8, and 11A, the substrate (804) of the circuit board (800) may include a first portion (804A) (or “first region”) connected to the substrate (801), a second portion (804B) connected to the first portion (804A) and bent from the first portion (804A), and a third portion (804C) connected to the second portion (804B) and bent from the second portion (804B). In other embodiments, at least one of the first portion (804A) and the second portion (804B) may be omitted.

[0219] For example, the first portion (804B) may extend in a direction parallel to the substrate (801). For example, the second portion (804B) may be bent from the first portion (804B) and may extend upward from the first portion (804B). For example, the third portion (804C) may extend from the second portion (804B) in a direction opposite to the first portion (804A).

[0220] For example, the substrate (804) may include a first bend (804D) connecting the first portion (804A) and the second portion (804B). The substrate (804) may also include a second bend (804E) connecting the second portion (804B) and the third portion (804C). The first bend (804D) and the second bend (804E) may be angular, but for example, the first portion (804A) and the second portion (804B) may be vertical. In other embodiments, the first bend (804D) and the second bend (804E) may be rounded. In other embodiments, the interior angle between the first portion (804A) and the second portion (804B) may be acute or obtuse.

[0221] The first bending portion (804D) and the second bending portion (804E) can prevent the length of the camera device (200) from increasing in the direction perpendicular to the optical axis direction. In addition, since the first bending portion (804D) and the second bending portion (804E) are positioned between the upper surface of the camera device (200) (e.g., the upper surface of the cover member (300)) and the lower surface of the camera device (200) (e.g., the lower surface of the housing (210)), the length of the camera device (200) can be prevented from increasing in the optical axis direction, thereby enabling miniaturization of the camera device.

[0222] For example, the third portion (804C) may be a plate or flat shape perpendicular to the optical axis. For example, the third portion (804C) may include a meandering shape or a serpentine shape. For example, the third portion (804C) may include at least one folded or curved region. For example, the folded or curved region of the third portion (804C) may be folded in a second direction or a third direction perpendicular to the optical axis. Alternatively, the folded or curved region of the third portion (804C) may extend in a direction perpendicular to the optical axis. For example, when viewed from above, the third portion (804C) may include a region having a U- or V-shape.

[0223] For example, the third portion (804C) may be spaced apart from the housing (210). For example, the third portion (804C) may be spaced apart from the protrusion (215) of the housing (210). In another embodiment, for example, at least a portion of the third portion (804C) may be in contact with the protrusion (215) of the housing (210).

[0224] At least a portion of the second portion (804B) of the substrate (804) may be positioned within the protrusion (215) of the housing (210). At least a portion of the second portion (804B) of the substrate (804) may be positioned within the groove (16A) of the protrusion (215) of the housing (210). For example, at least a portion of the first portion (804A) of the substrate (804) may be positioned within the groove (16A) of the protrusion (215) of the housing (210). The third portion (804B) of the substrate (804) may be positioned outside the protrusion (215) of the housing (210). For example, the third portion (804B) of the substrate (804) may be positioned above the protrusion (215) of the housing (210). The lower surface of the third part (804B) of the substrate (804) may be positioned above the upper surface of the protrusion (215) of the housing (210).

[0225] Referring to FIG. 7A, the sensor base (270) may include a groove (273) formed at a location where the substrate (804) and the substrate (801) meet or are connected, for example, at a location corresponding to the first portion (804A) of the substrate (804). The groove (273) may be positioned adjacent to or in contact with the outer surface of the fourth side (51D) of the sensor base (270) on which the substrate (804) is placed. The groove (273) may serve to prevent the first portion (804A) of the substrate (804) from being damaged by friction with the sensor base (270).

[0226] The connector (805) can be coupled or connected to another connector or external device outside of the camera device (200). The connector (805) connected to another external connector may correspond to a fixed part that does not move when the OIS is driven. Since the third part (804C) of the substrate (804) includes at least one bent or curved area, it can resiliently support the camera device (200) or the OIS moving part and can serve to alleviate external impact. That is, the third part (804C) of the substrate (804) can serve as a spring that alleviates impact. In addition, since the third part (804C) of the substrate (804) can serve to resiliently support the OIS moving part (100), it can reduce the driving force or driving power required when the OIS is driven.

[0227] Referring to FIGS. 11A and 11B , the camera device (200) may include a reinforcing member (70, 70-1) disposed, coupled, or attached to at least a portion of the substrate (804). The reinforcing member (70, 70-1) may be disposed, coupled, or attached to at least one of the first portion (804A) and the second portion (804B) of the substrate (804). For example, the reinforcing member (70, 70-1) may be disposed, coupled, or attached to at least a portion of the first portion (804A) and at least a portion of the second portion (804B) of the substrate (804).

[0228] For example, the reinforcing member (70, 70-1) may be disposed, coupled, or attached to the lower surface of the first portion (804A) and the lower surface of the second portion (804B) of the substrate (804). For example, the reinforcing member (70, 70-1) may include a first region (70A) disposed, coupled, or attached to the first portion (804A) and a second region (70B) disposed, coupled, or attached to the second portion (804B). The second region (70B) may be bent upward from the first region (70A). For example, a bent portion may be formed between the first region (70A) and the second region (70B). For example, the area of ​​the second region (70B) may be larger than the area of ​​the first region (70A). In other embodiments, the two may be the same or the area of ​​the former (70B) may be smaller than the area of ​​the latter (70A).

[0229] For example, the reinforcing member (70, 70-1) may be spaced apart from the third portion (804C) of the substrate (804). For example, the second region (70B) of the reinforcing member (70, 70-1) may be spaced apart from the third portion (804C) of the substrate (804). In another embodiment, at least a portion of the second region (70B) of the reinforcing member (70, 70-1) may be in contact with the third portion (804C) of the substrate (804).

[0230] In another embodiment, the reinforcing member (70, 70-1) may be positioned, coupled, or attached to the upper surface of the first portion (804A) and the upper surface of the second portion (804B) of the substrate (804). For example, in another embodiment, the reinforcing member (70, 70-1) may include a first region positioned on the upper surface of the first portion (804A) of the substrate (804) and a second region positioned on the upper surface of the second portion (804B).

[0231] In another embodiment, the reinforcing member (70, 70-1) may be positioned, coupled, or attached to at least a portion of the second portion (804B) and at least a portion of the third portion (804C) of the substrate (804). For example, in another embodiment, the reinforcing member (70, 70-1) may be positioned, coupled, or attached to the second portion (804B) and the third portion (804C) of the substrate (804). For example, the reinforcing member (70, 70-1) may include a first region that is positioned, coupled, or attached to the second portion (804B) of the substrate (804) and a second region that is positioned, coupled, or attached to the third portion (804C), and a bend portion may be formed between the first region and the second region. The first region of the reinforcing member (70, 70-1) can be placed on the lower surface (or upper surface) of the second portion (804B), and the second region of the reinforcing member (70, 70-1) can be placed on the lower surface (or upper surface) of the third portion (804C).

[0232] The reinforcing member (70, 70-1) can prevent the substrate (804) from being damaged, deformed, or broken by impact or external force. In addition, the reinforcing member (70, 70-1) can serve to suppress the shape of the substrate (804) from being deformed and restored due to force applied to the substrate (804) by tilting the OIS moving part (100). For example, the reinforcing member (70, 70-1) can include at least one of a metal material or an injection-molded material.

[0233] For example, the reinforcing member (70, 70-1) may be positioned inside the groove (16A) of the protrusion (215) of the housing (210). For example, the reinforcing member (70, 70-1) may at least partially contact the groove (16A) of the protrusion (215) of the housing (210). For example, the reinforcing member (70, 70-1) may not be coupled to the housing (210) (e.g., the protrusion (215)). In another embodiment, for example, the reinforcing member (70, 70-1) may be coupled to the housing (210) (e.g., the protrusion (215)) by an adhesive.

[0234] The reinforcing member (70) of FIG. 11A may include an opening (73). The opening (73) of the reinforcing member (70) may open or expose at least a portion of the substrate (804) of the circuit board (800). For example, the opening (73) may open or expose at least a portion of a first portion (804A) (or “first region”) and a second portion (804B) (or “second region”) of the substrate (804). The opening (73) of the reinforcing member (70) may be a hole, a through hole, or a hollow.

[0235] The opening (73) may be formed in at least one of the first region (70A) and the second region (70A) of the reinforcing member (70). For example, the opening (73) may be formed in the first region (70A) and the second region (70A) of the reinforcing member (70). In addition, the opening (73) may open or expose at least a portion of the first bent portion (804D). In other embodiments, the opening (73) may be formed in only one of the first region (70A) and the second region (70A) of the reinforcing member (70). In other embodiments, the opening (73) may not expose the first bent portion (804D).

[0236] The elastic coefficient of the substrate (804) of the circuit board (800) coupled with the reinforcing member (70) by the opening (73) can be reduced, and the movement of the OIS moving part can be facilitated when the OIS is driven. That is, the elasticity of the circuit board (800), for example, the substrate (804) supporting the OIS moving part, can be reduced by the opening (73), and thus, the OIS can be easily driven with a small driving force, and the power consumption can be reduced. At this time, the driving force may be a force resulting from the interaction between the coil (230) and the magnet (310).

[0237] In FIG. 8, a gap may exist between the side area of ​​the housing (210) excluding the protrusion (216) and the lower part of the lens holder (110), and in order to prevent foreign substances from entering, the camera device (200) may include a cover or shield covering the lower part of the lens holder (110) and the side of the housing (210). For example, the cover or shield may be in the form of an adhesive tape.

[0238] Referring to FIG. 1, FIG. 10A and FIG. 10B, the movement restraining member (80) can be coupled with the protrusion (215) of the housing (210). For example, the movement restraining member (80) can be coupled with the coupling groove (215A, 215B) of the protrusion (215) of the housing (210).

[0239] Referring to FIG. 3, at least a portion of the second portion (804B) of the substrate (804) may be disposed between the movement-restraining portion (80) and the inner surface of the protrusion (215) of the housing (210). For example, at least a portion of the reinforcing member (70) may be disposed between the movement-restraining portion (80) and the inner surface of the protrusion (215) of the housing (210). The movement-restraining portion (80) may be spaced apart from the circuit board (800) in the second direction (X-axis direction) or the third direction (Y-axis direction). For example, the movement-restraining portion (800) may be spaced apart from the circuit board (800) in the optical axis direction or in a direction perpendicular to the optical axis direction. That is, the movement-restraining portion (800) may serve to maintain the shape of the bent portions (804D, 804E) of the substrate (804), which is a flexible substrate. For example, the movement restraining member (80) may be an injection molded product made of a non-magnetic material or resin. In another embodiment, the movement restraining member (80) may be in contact with at least a portion of the substrate (804) of the circuit board (800).

[0240] At least a part of the second part (804B) of the substrate (804) positioned within the groove (16A) of the protrusion (215) can be restricted from moving or moving by the movement restraining member (800), and the second part (804B) can be restrained or prevented from moving out of the groove (16A) of the protrusion (215). As a result, the OIS moving part can be restrained or prevented from being affected by the restoring force of the substrate (804) during OIS operation, thereby enabling accurate OIS operation and improving the reliability of OIS operation. The movement restraining member (800) can also be expressed as a “clamp”.

[0241] The cover member (300) may form a receiving space together with the housing (210), and an OIS moving part may be placed within the receiving space. For example, the cover member (300) may be in the shape of a box with an open bottom. For example, the cover member (300) may include an upper plate (301) and a side plate (302) connected to the upper plate (301).

[0242] The lower end of the side plate (302) of the cover member (300) can be combined with the housing (210). The shape of the upper plate (302) of the cover member (300) can be polygonal (e.g., square or octagonal) or circular. The upper plate (302) of the cover member (300) can include an opening (303) for exposing a lens (not shown) to external light. The opening (303) can be a through hole that penetrates the upper plate (302) of the cover member (300) in the direction of the optical axis. For example, the number of side plates of the cover member (300) can be plural. The material of the cover member (300) can be a non-magnetic substance. In another embodiment, the cover member (300) can be a magnetic substance. For example, the material of the cover member (300) can be an injection-molded product such as a resin or a metal material.

[0243] Referring to FIGS. 1 and 2A, the cover member (300) may include an opening (304) positioned or formed in the side plate (302) to avoid spatial interference with the protrusion (215) of the housing (210). For example, the protrusion (216) of the housing (210) may pass through the opening (304) of the cover member (300) and protrude from the side plate (302) of the cover member (300).

[0244] The cover member (300) may include a protrusion (305) that is disposed over the opening (304) and protrudes from the side plate (302). For example, the protrusion (305) may have a plate shape. For example, the protrusion (305) of the cover member (300) may be disposed on the protrusion (215) of the housing (210). For example, the protrusion (305) may be disposed above the groove (16A) of the protrusion (215) of the housing (210). For example, the protrusion (305) may be disposed above the movement-restraining member (80). For example, the protrusion (305) may overlap the movement-restraining member (80) in the optical axis direction. Additionally, for example, the protrusion (305) may overlap the first portion (804A) of the substrate (804) in the optical axis direction. The protrusion (305) can suppress or prevent the movement restraining member (80) from being detached, and can protect the movement restraining member (80) and the substrate (804) from impact.

[0245] The following describes the support.

[0246] The support may be arranged between the fixed portion and the OIS moving portion (100). The support may be arranged between the sensor base (270) and the housing (210) and may support the sensor base (270) with respect to the housing (210). The support may include a tilting guide portion (60) arranged between the OIS moving portion (e.g., the sensor base (270)) and the fixed portion (e.g., the housing (210)). The tilting guide portion (60) may guide the tilting of the OIS moving portion (100).

[0247] The tilting guide part (60) may be expressed as a driving plate, “mover”, “mover plate”, “driving plate”, “plate”, “rotary plate”, “tilting plate”, “moving plate”, or “support plate”.

[0248] The tilting guide unit (60) may be tilted or rotated by a preset angle based on the first axis or the second axis. For example, the tilting guide unit (60) may be positioned between the lower portion (or bottom surface) of the sensor base (270) and the lower portion (42) of the housing (210). For example, at least a portion of the tilting guide unit (60) may be positioned within the mounting portion (69) of the housing (210). Since the tilting guide unit (60) is positioned within the mounting portion (69) of the housing (210), the length or height of the camera device (200) in the optical axis direction may be reduced.

[0249] Referring to FIGS. 4B, 9A, and 12, the tilting guide portion (60) may be plate-shaped. The tilting guide portion (60) may include a body. The body may be alternatively expressed as a main body or a “plate portion.” When viewed from above, the shape of the body of the tilting guide portion (60) may be polygonal (e.g., square), circular, or oval. When viewed from above, the shape of the body of the tilting guide portion (60) may be square, and the corner (or edge) portion of the body may be rounded.

[0250] The length of the tilting guide part (60) in a horizontal direction (e.g., a horizontal direction or a vertical direction) perpendicular to the optical axis may be greater than the length of the tilting guide part (60) in the optical axis direction. The tilting guide part (60) may include a first guide member arranged on a first surface (or upper surface) (6A) facing the OIS moving part (e.g., the sensor base (270)) and a second guide member arranged on a second surface (or lower surface) (6B) facing the fixed part (e.g., the housing (210)).

[0251] There may be at least one first guide member, and there may be at least one second guide member. For example, a first axis may be formed by the first guide member, and a second axis may be formed by the second guide member. For example, the first guide member may include a plurality of first guide members spaced apart in a direction parallel to the first axis. The second guide member may include a plurality of second guide members spaced apart in a direction parallel to the second axis. For example, the first axis may be formed by the plurality of first guide members, and the second axis may be formed by the plurality of second guide members. The first guide member may be a “protrusion,” a “protrusion,” a “ball member,” or a “ball,” and the second guide member may be a “protrusion,” a “protrusion,” a “ball member,” or a “ball.”

[0252] Referring to FIGS. 9A and 9B, the tilting guide portion (60) may include a first protrusion (65) coupled with or in contact with the sensor base (270) and a second protrusion (66) coupled with or in contact with the housing (210). The first protrusion (65) may be disposed on a first surface (6A) (e.g., an upper surface) of the tilting guide portion (60), and the second protrusion (66) may be disposed on a second surface (6B) (or a lower surface) of the tilting guide portion (60) which is the opposite surface of the first surface (6A). For example, the first protrusion (65) may protrude from the first surface (6A) (e.g., the upper surface) of the tilting guide portion (60), and the second protrusion (66) may protrude from the second surface (6B) (e.g., the lower surface) of the tilting guide portion (60).

[0253] The first protrusion (65) may be expressed as an “upper protrusion (or front protrusion)” or a “first protrusion”, and the second protrusion (66) may be expressed as an “lower protrusion (or rear protrusion)” or a “second protrusion”. The number of each of the first protrusion (65) and the second protrusion (66) may be 1, 2, 3 or more.

[0254] At least a portion of the first protrusion (65) may be disposed within the groove (29) of the sensor base (270). The first protrusion (65) may include at least two protrusions (65A, 65B). For example, the first-first protrusion (65A) and the first-second protrusion (65B) may be disposed spaced apart from each other in the first axial direction. Each of the two protrusions (65A, 65B) may be disposed inserted into a corresponding one of the first and second grooves (29A, 29B) of the sensor base (270). In another embodiment, the two protrusions (65A, 65B) may be disposed spaced apart from each other in the first horizontal direction or the X-axis direction.

[0255] At least a portion of the second protrusion (66) may be positioned within the groove (55) of the housing (210).

[0256] The second protrusion (66) may include at least two protrusions (66A, 66B). For example, the second-first protrusion (66A) and the second-second protrusion (66B) may be spaced apart from each other in the second axis direction. Each of the two protrusions (66A, 66B) may be inserted into and positioned in a corresponding one of the first and second grooves (55A, 55B) of the housing (210). In another embodiment, the two protrusions (66A, 66B) may be spaced apart from each other in the second horizontal direction or the Y-axis direction.

[0257] In another embodiment, the two protrusions (65A, 65B) of the tilting guide part (60) may be arranged spaced apart in the second axis direction, the first and second grooves (29A, 29B) of the sensor base (270) may be arranged spaced apart in the second axis direction, the two protrusions (66A, 66B) of the tilting guide part (60) may be arranged spaced apart in the first axis direction, and the first and second grooves (55A, 55B) of the housing (210) may be arranged spaced apart in the first axis direction.

[0258] For example, each of the first protrusion (65) and the second protrusion (66) may have a curved shape, a hemispherical shape, a dome shape, or a polyhedral shape, but is not limited thereto. For example, the shape of the first protrusion (65) when viewed from the front or upper side and the shape of the second protrusion (66) when viewed from the rear or lower side may be circular, oval, or polygonal.

[0259] The tilting guide part (60) may include an opening (60A) corresponding to, opposite to, or overlapping with the magnetic body (31) or / and the magnetic body (33) in the optical axis direction. For example, the opening (60A) may correspond to, opposite to, or overlap with the coupling part (49) of the housing (210) in the optical axis direction. The opening (60A) may reduce the weight (or weight) of the tilting guide part (60), thereby making the camera device (200) lighter.

[0260] For example, the opening (60A) of the tilting guide portion (60) may be positioned at a position corresponding to the coupling portion (49) in order to avoid spatial interference with the coupling portion (49) of the housing (210). In addition, the opening (60A) of the tilting guide portion (60) may be formed in order to avoid spatial interference with the magnetic body (31) and the coupling portion (49) of the housing (210).

[0261] For example, the opening (60A) of the tilting guide part (60) may be a through hole or a hollow. For example, the opening (60A) may penetrate the tilting guide part (60) in the first direction (Z-axis direction) or the optical axis direction. For example, at least a portion of the opening (60A) of the tilting guide part (60) may have a shape corresponding to the coupling part (49) of the housing (210). For example, the opening (60A) may have a circular, oval, polygonal, for example, rectangular shape.

[0262] When viewed from above, the opening (60A) of the tilting guide part (60) can be positioned between the protrusions (65A, 65B) of the tilting guide part (60). When viewed from below, the opening (60A) of the tilting guide part (60) can be positioned between the protrusions (66A, 66B) of the tilting guide part (60).

[0263] For example, the horizontal length of the opening (60A) of the tilting guide portion (60) may be greater than the horizontal length of the coupling portion (49) of the housing (210). In another embodiment, the horizontal length of the opening (60A) may be the same as the horizontal length of the coupling portion (49) of the housing (210). The vertical length of the opening (60A) may be greater than the vertical length of the coupling portion (49) of the housing (210). In another embodiment, the vertical length of the opening (60A) may be the same as the vertical length of the coupling portion (49) of the housing (210).

[0264] At least a portion of the coupling portion (49) of the housing (210) may be positioned within the opening (60A) of the tilting guide portion (60). For example, the coupling portion (49) of the housing (210) may overlap with the opening (60A) of the tilting guide portion (60) in the optical axis direction. Also, for example, the coupling portion (49) of the housing (210) may overlap with the tilting guide portion (60) in a direction perpendicular to the optical axis direction. This may reduce the length or height of the camera device (200) in the optical axis direction.

[0265] For example, at least a portion of the opening (60A) may be positioned between two protrusions (65A, 65B) of the first protrusion (65) of the tilting guide portion (60). Also, at least a portion of the opening (60A) may be positioned between protrusions (66A, 66B) of the second protrusion (66) of the tilting guide portion (60).

[0266] For example, the tilting guide part (60) may be an injection molded product. For example, the tilting guide part (60) may be made of plastic, resin, or ceramic. In another embodiment, the tilting guide part (60) may include a metal material, for example, SUS material. In addition, the tilting guide part (60) may be a non-magnetic material. In another embodiment, the tilting guide part (60) may be a magnetic material.

[0267] The protrusions (65A, 65B) of the first protrusion (65) and the protrusions (66A, 66B) of the second protrusion (66) can be arranged in parallel along directions that intersect or are perpendicular to each other. The OIS moving unit can be rotated, pivotally rotated, or tilted by a preset angle based on the first axis by the first protrusion (65) of the tilting guide unit (60). And the OIS moving unit can be rotated, pivotally rotated, or tilted based on the second axis by the second protrusion (66) of the tilting guide unit (60).

[0268] In another embodiment, the tilting guide portion (60) may omit at least one of the first protrusion (65) and the second protrusion (66), and a cloud member or a ball member may be placed instead of the omitted protrusion.

[0269] Referring to FIGS. 9C and 9D , a tilting guide part (60-1) according to another embodiment may include a first groove (75) without the first protrusion (65), and may include a second groove (76) without the second protrusion (66). In addition, the support part may include a first ball member instead of the first protrusion (65), and may include a second ball member instead of the second protrusion (66). For example, the first ball member may include two or more first ball members (65A1, 65B1), and the second ball member may include two or more ball members (66A1, 66B1).

[0270] The first groove (75) may be arranged or formed on the first surface (6A) of the tilting guide portion (60-1). The first surface (6A) may be a surface facing or opposing the sensor base (270). The groove (75) may be recessed from the first surface (6A) of the tilting guide portion (60). For example, the tilting guide portion (60-1) may include first grooves (75A, 75B) for arranging at least a portion of the two first ball members (65A1, 65B1). For example, the first grooves (75A, 75B) may be arranged to be spaced apart from each other in the first axis direction. For example, the first ball members (65A1, 65B1) may be arranged to be spaced apart from each other in the first axis direction.

[0271] In another embodiment, the first ball members (65A1, 65B1) may be arranged spaced apart in the second axis direction, and the first grooves (75A, 75B) may be arranged spaced apart in the second axis direction.

[0272] In another embodiment, the first ball members (65A1, 65B1) and the first grooves (75A, 75B) may be spaced apart in the first horizontal direction (or the second horizontal direction).

[0273] In addition, the second groove (76) of the tilting guide part (60-1) may be arranged or formed on the second surface (6B) of the tilting guide part (60-1). The second surface (6B) may be a surface facing or opposing the housing (210). In addition, the second surface (6B) may be an opposite surface of the first surface (6A) of the tilting guide part (60-1). The second groove (76) may be recessed from the second surface (6B) of the tilting guide part (60).

[0274] For example, the tilting guide portion (60-1) may include second grooves (76A, 76B) for arranging at least a portion of two second ball members (66A1, 66B1). For example, the second grooves (76A, 76B) may be arranged to be spaced apart in the second axial direction. For example, the second ball members (66A1, 66B1) may be arranged to be spaced apart in the second axial direction. In another embodiment, the second ball members (66A1, 66B1) may be arranged to be spaced apart in the first axial direction, and the second grooves (76A, 76B) may be arranged to be spaced apart in the first axial direction. In yet another embodiment, the second ball members (66A1, 66B1) and the second grooves (76A, 76B) may be arranged to be spaced apart in the second horizontal direction (or the first horizontal direction).

[0275] The description of the shape of the groove (29) of the sensor base (270) or the groove (55) of the housing (210) can be applied or analogized to the shape of the first groove (75) and the second groove (76) of the tilting guide part (60-1).

[0276] A lubricant may be placed between the first protrusion (66) of the tilting guide part (60) and the groove (29) of the sensor base (270) or the second protrusion (66) of the tilting guide part (60) and the groove (55) of the housing (210) to reduce friction and protect the tilting guide part (60).

[0277] The first protrusion (65) of the tilting guide part (60) can slide within the groove (29) of the sensor base (270), and the second protrusion (66) can slide within the groove (55) of the housing (210). This can reduce the friction between the tilting guide part (60) and the sensor base (270) and / or the friction between the tilting guide part (60) and the housing (210), and can reduce the current consumption or power consumption for driving the OIS.

[0278] The support member may include a magnetic body (33) disposed on an OIS moving member (e.g., a sensor base (270)) and a magnetic body (31) disposed on a fixed member (e.g., a housing (210)). The magnetic bodies (31, 33) may be alternatively expressed as a “magnet,” a “yoke,” or a “holding magnet.” The support member may further include a support member (64).

[0279] For example, the magnetic body (31) may be placed in the groove (49A) of the coupling portion (49) of the housing (210) or may be combined with the groove (49A). At least a portion of the magnetic body (31) may be placed in the opening (60A) of the tilting guide portion (60). For example, the magnetic body (31) may face or overlap with the opening (60A) of the tilting guide portion (60) in the optical axis direction. For example, the magnetic body (31) may not overlap with the tilting guide portion (60) in the optical axis direction. Also, for example, at least a portion of the magnetic body (31) may overlap with the tilting guide portion (60) in a direction perpendicular to the optical axis. For example, the magnetic body (31) may overlap with the tilting guide portion (60) in a direction parallel to the first axis or a direction parallel to the second axis. The magnetic body (31) may correspond to, face, or overlap with the magnetic body (33) in the direction of the optical axis. The magnetic body (31) may be placed on the opposite side of the magnetic body (33).

[0280] The magnetic body (31) may be a two-pole magnet divided or arranged into N and S poles. For example, the magnetic body (31) may be a two-pole magnet divided or arranged into N and S poles in the direction of the optical axis. In another embodiment, the magnetic body (31) may be a two-pole magnet divided or arranged into N and S poles in a direction perpendicular to the optical axis. In yet another embodiment, the magnetic body (31) may be a four-pole magnet including two N poles and two S poles.

[0281] The support member (64) can be coupled or assembled with the OIS moving part. For example, the support member (64) can be coupled with the sensor base (270) or assembled to the sensor base (270). For example, the support member (64) can be coupled with the extension (217) of the sensor base (270) or assembled to the extension (217). For example, the support member (64) can be coupled with the extension (217) of the sensor base (270) by an adhesive.

[0282] The support member (64) may be alternatively expressed as a “magnetic support member”, “sensor base rigid”, “support”, “mover rigid”, “holding rigid”, “joint”, or “plate”. For example, the support member (64) may be formed of an injection-molded material, plastic, or resin material, or, for example, the support member (64) may be formed of a metal material or a metal plate. Alternatively, the support member (64) may be formed of a heat dissipation material. The support member (64) may have a polyhedral (e.g., hexahedral) shape. The support member (64) may have a plate shape. For example, when viewed from above or in the direction of the optical axis, the support member (64) may have a polygonal, e.g., square, shape. For example, when viewed from above or in the direction of the optical axis, the support member (64) may have a rectangular, square, circular, or oval shape.

[0283] Fig. 14a is a cutaway perspective view of a camera device (200), and Fig. 14b is an enlarged view of the dotted line portion of Fig. 14a.

[0284] Referring to FIGS. 14A and 14B, the support member (64) may be positioned spaced apart from the tilting guide member (60). The support member (64) may be positioned below the tilting guide member (60) (or the body of the tilting guide member (60)). The image sensor (801) may be positioned closer to the magnetic body (31) than to the magnetic body (33).

[0285] At least a portion of the support member (64) may overlap with the magnetic body (31) in the optical axis direction. At least a portion of the support member (64) may overlap with the magnetic body (33) in the optical axis direction. The support member (64) may overlap with the opening (60A) of the tilting guide part (60) in the optical axis direction. The support member (64) may be positioned below the opening (60A) of the tilting guide part (60). The support member (64) may not overlap with the tilting guide part (60) in the optical axis direction. The support member (64) may correspond to, face, or overlap with the extension part (217) of the sensor base (270) in the optical axis direction. For example, the support member (64) may not overlap with the body of the tilting guide part (60) in a direction perpendicular to the optical axis direction. The lower surface of the support member (64) may be positioned higher than the lower surface of the lower surface (42) of the housing (210). In other embodiments, the lower surface of the support member (64) may be positioned lower than the lower surface of the lower surface (42) of the housing (210) or at the same height as the lower surface of the lower surface (42) of the housing (210).

[0286] For example, the support member (64) may not overlap with the magnet (310) or / and the coil (230) in the optical axis direction. The support member (64) may overlap with the image sensor (810) in the optical axis direction.

[0287] The moving module may include a portion (or “first portion”) that passes through the opening (60A) of the tilting guide portion (60) or is positioned within the opening (60A) of the tilting guide portion (60). The magnetic body (33) may be coupled to the portion (or “first portion”) of the moving module. For example, the magnetic body (33) may be coupled to the first portion of the moving module by an adhesive. For example, the sensor base (270) may include the first portion.

[0288] The support member (64) can be coupled to the first part of the moving module. The magnetic body (33) can be placed on the support member (64). For example, the “first part” of the moving module can be an extension (217) of the sensor base (270). The fixed part can include an opening (18) in which the first part of the moving module is placed.

[0289] At least a portion of the extension (217) of the sensor base (270) may correspond to, face, or overlap with the opening (60A) of the tilting guide portion (60) in the optical axis direction. For example, the extension (217) may not overlap with the tilting guide portion (60) in the optical axis direction. In another embodiment, a portion of the extension (217) may overlap with the tilting guide portion (60) in the optical axis direction.

[0290] At least a portion of the extension (217) may be positioned within the opening (60A) of the tilting guide (60). For example, at least a portion of the extension (217) may pass through the opening (60A) of the tilting guide (60). For example, at least a portion of the extension (217) may pass through or penetrate the opening (60A) of the tilting guide (60) and be coupled to the support member (64). That is, as illustrated in FIGS. 4B and 14B, the end of the extension (217) may be positioned below the lower surface of the tilting guide (60).

[0291] In another embodiment, the end of the extension (217) may be positioned within the opening (60A) of the tilting guide (60). For example, the end of the extension (217) may be positioned between the upper and lower surfaces of the tilting guide (60).

[0292] In the embodiment of FIG. 7d, the extension (217) corresponds to a part of the sensor base (270) and may be formed integrally with the sensor base (270). A camera device according to another embodiment may have a separate coupling member from the sensor base (270) instead of the extension (217). In this case, the separate coupling member may be coupled to the sensor base (270). For example, the coupling member may be coupled to the sensor base (270) by an adhesive. For example, the coupling member may include a first coupling structure (e.g., a protrusion or a groove), and the sensor base (270) may include a second coupling structure (e.g., a groove or a protrusion) for coupling with the first coupling structure. For example, one end of the coupling member may be coupled to the lower portion (or bottom surface) of the sensor base (270), and the other end of the coupling member may be coupled to the support member (64). At least a portion of the coupling member may be positioned within the opening (60A) of the tilting guide member (60). The coupling member may pass through the opening (60A) of the tilting guide member (60) and be coupled to the support member (64). In this case, the sensor base (270) may not include a portion positioned within the opening (60A) of the tilting guide member (60).

[0293] In an embodiment, the support member (64) can be coupled to the extension (217) of the sensor base (270) that passes through the opening (60A) of the tilting guide member (60) and does not overlap with the body of the tilting guide member (60) in the optical axis direction. That is, the size of the support member (64) can be reduced and the shape can be simplified.

[0294] In a camera device according to a comparative example, the support member may overlap at least a portion of the tilting guide member in the direction of the optical axis, and the support member may include an extension portion extending to at least one corner portion of the housing.

[0295] In order for the moving part (e.g., the sensor base (270)) to tilt about the first or second axis, a space is required between the sensor base (270) and the housing (210). In the comparative example, the space for the sensor base (270) to tilt about the first or second axis can be increased by the extension of the support member.

[0296] On the other hand, in the embodiment, the support member (64) may have a simple structure that does not overlap with the tilting guide part (60) in the optical axis direction. In the embodiment, the size of the support member (64) may be designed to be small. In addition, in the embodiment, the end of the support member (64) may be positioned closer to the center or central region of the optical axis or the tilting module rather than the corner of the housing (210). Therefore, compared to the comparative example, in the embodiment, the space required for tilting the sensor base, which is the OIS moving part, for image stabilization can be reduced, and the size of the camera device can be reduced.

[0297] The magnetic body (33) may be placed on the lower side of the magnetic body (31). The magnetic body (31) may be positioned higher than the magnetic body (33). The magnetic body (33) may be placed on the support member (64). The magnetic body (33) may be coupled to the support member (64). Referring to FIG. 7A, the support member (64) may include a mounting portion (93A) (or receiving portion). The mounting portion (93A) may be a groove. For example, the mounting portion (93A) may be a groove that is recessed from the upper surface of the support member (64). For example, the magnetic body (33) may be coupled to the mounting portion (93A) of the support member (64). For example, the magnetic body (33) may be coupled, attached, or fixed to the mounting portion (93A) of the support member (64) by an adhesive. The magnetic body (33) may overlap with the opening (60A) of the tilting guide part (60) in the direction of the optical axis. The magnetic body (33) may not overlap with the tilting guide part (60) in the direction of the optical axis.

[0298] Referring to FIGS. 14A and 14B, the magnetic body (33) may not overlap with the tilting guide part (60) in a direction perpendicular to the optical axis. In another embodiment, the magnetic body (33) may overlap with the tilting guide part (60) in a direction perpendicular to the optical axis. When viewed from above, the area of ​​the opening (60A) of the tilting guide part (60) may be larger than the area of ​​the upper surface (or lower surface) of the magnetic body (31). In addition, when viewed from above, the area of ​​the opening (60A) of the tilting guide part (60) may be larger than the area of ​​the upper surface (or lower surface) of the magnetic body (33).

[0299] A repulsive force may be applied between the magnetic body (33) and the magnetic body (31) in the direction of the optical axis (or the first direction). The magnetic body (33) and the magnetic body (31) may be arranged so that a repulsive force is applied to each other. The magnetic body (33) may be made of a material having magnetism. For example, the magnetic body (33) may include a metallic material having magnetism. Or, for example, the magnetic body (33) may be made of a metallic material having magnetism. Or, for example, the magnetic body (33) may be a magnet. The magnetic bodies (31, 33) may be expressed as a "yoke". Each of the magnetic bodies (33, 31) may also be expressed as a "repulsive magnet".

[0300] For example, the magnetic body (33) and the magnetic body (31) may be arranged so that their faces facing or opposing each other in the optical axis direction have the same polarity. For example, the N pole (or S pole) of the magnetic body (33) and the N pole (or S pole) of the magnetic body (31) may face or oppose each other in the optical axis direction.

[0301] For example, the first surface of the magnetic body (33) may face the first surface of the magnetic body (31), and the first surface of the magnetic body (33) and the first surface of the magnetic body (31) may have the same polarity. For example, the second surface of the magnetic body (33) may be the opposite surface of the first surface of the magnetic body (33), the second surface of the magnetic body (31) may be the opposite surface of the first surface of the magnetic body (31), and the second surface of the magnetic body (33) and the second surface of the magnetic body (31) may have the same polarity.

[0302] Referring to FIGS. 14a and 14b, the coupling portion (49) of the housing (210) may be disposed between the sensor base (210) and the support member (64). The coupling portion (49) and the magnetic body (31) may be disposed between the sensor base (270) and the magnetic body (33) disposed on the support member (64). In the optical axis direction, the coupling portion (49) of the housing (210) and the magnetic body (33) may face each other or overlap. In the optical axis direction, the coupling portion (49) of the housing (210) may overlap with the support member (64).

[0303] The image sensor (810) or filter (610) may be positioned closer to the magnetic body (31) than to the magnetic body (33). That is, among the magnetic body (31) and the magnetic body (33), the magnetic body (31) may be positioned closer to the image sensor (810). For example, the lower surface of the lower portion (42) of the housing (210) may be positioned closer to the magnetic body (33) than to the magnetic body (31). For example, the support member (64) and the magnetic body (33) may be positioned below the tilting guide portion (60).

[0304] The tilting guide part (60) can be brought into close contact with the OIS moving part and fixed part by the repulsive force acting between the magnetic body (33) and the magnetic body (31). The tilting guide part (60) can be pressed against the moving part by the repulsive force between the magnetic body (33) and the magnetic body (31).

[0305] The lower surface of the sensor base (270) can press the first protrusion (65) of the tilting guide part (60) due to the repulsive force acting between the magnetic body (33) and the magnetic body (31). The lower portion (42) of the housing (210) can press the protrusion (66) of the tilting guide part (60) due to the repulsive force acting between the magnetic body (33) and the magnetic body (31). As a result, the first protrusion (65) and the second protrusion (66) of the tilting guide part (60) can be brought into close contact with the sensor base (270) and / or the housing (210). The tilting guide part (60) can stably support the OIS moving part (100) with respect to the fixed part due to the repulsive force between the magnetic body (33) and the magnetic body (31), and a stable OIS operation can be performed.

[0306] In addition, since at least a part of the magnetic body (31) is placed within the opening (60A) of the tilting guide part (60), the separation distance between the magnetic body (31) and the magnetic body (33) can be reduced, thereby increasing the repulsive force between the magnetic body (31) and the magnetic body (33), and the OIS moving part can be stably supported on the fixed part, and stable OIS operation can be performed.

[0307] In addition, since the magnetic body (31) is placed in a joint portion (49) corresponding to or opposite the central region of the lower portion (42) of the housing (210), and the magnetic body (33) is placed in an area of ​​the support member (64) corresponding to or opposite the central region of the lower surface of the sensor base (270), the repulsive force between the magnetic bodies (31) and (33) can be concentrated in the central region of the sensor base (270) and the central region of the housing (210), and thus the OIS moving part can be supported efficiently and stably.

[0308] In another embodiment, the coupling portion (49) of the housing (210) may be omitted, and the magnetic body (31) may be placed on the upper surface of the lower portion (42) of the housing (210). In addition, the mounting portion (69) of the housing (210) may be omitted, and a mounting portion corresponding to or identical to the mounting portion (69) of the housing (210) may be formed on the lower surface of the sensor base (270), and the tilting guide portion (60) may be placed within the mounting portion of the sensor base (270).

[0309] In another embodiment, the tilting guide unit (60) may be omitted, and the support unit may include a cloud member, for example, a ball member, disposed between the sensor base (270) and the housing (210). In this case, the cloud member may include two first ball members disposed in a direction parallel to one axis and two second ball members disposed in a direction parallel to the second axis, and the OIS moving unit may tilt the first ball members about an axis or rotate them by a preset angle, and may tilt the second ball members about an axis or rotate them by a preset angle, and a shake correction operation may be performed according to the result.

[0310] Referring to FIG. 12 and FIG. 16A, when viewed from above, the first magnet unit (310A) may overlap with the protrusions (65A, 65B) in the direction in which the protrusions (65A, 65B) of the tilting guide portion (60) face each other or in the first axis direction. In addition, the second magnet unit (310B) may overlap with the protrusions (65A, 65B) in the direction in which the protrusions (66A, 66B) of the tilting guide portion (60) face each other or in the second axis direction.

[0311] Referring to FIGS. 4d and 4e, the tilting guide unit (60) can overlap with the magnet (310) in a direction perpendicular to the optical axis. For example, the first magnet unit (310A) can overlap with the tilting guide unit (60) in the first axis direction, and the second magnet unit (310B) can overlap with the tilting guide unit (60) in the second axis direction.

[0312] For example, the magnet (310) and the yoke (380) may be positioned below the image sensor (810). For example, the magnet (310) may be positioned below the filter (610). Additionally, the magnet (310) may be positioned below the magnetic body (33). For example, the magnet (310) may be positioned below the lens holder (110). For example, the magnet (310) may be positioned below the sensor base (270). For example, the upper surface of the magnet (310) may be positioned below the lower surface of the sensor base (270). The upper surface of the magnet (310) may be positioned below the lower surface of the lens holder (110). The upper surface of the magnet (310) may be positioned below the lower surface of the magnetic body (33).

[0313] Referring to FIG. 4f, for example, the upper surface of the magnet (310), for example, the upper surface of the magnet unit (310A, 310B), may be positioned lower than the upper surface of the magnetic body (31). In another embodiment, the upper surface of the magnet (310) may be positioned higher than the upper surface of the magnetic body (31) or may be the same height as the upper surface of the magnetic body (31).

[0314] For example, the upper surface of the magnet (310), for example, the upper surface of the magnet unit (310A, 310B), may be positioned lower than the lower surface of the magnetic body (31). In another embodiment, the upper surface of the magnet (310) may be positioned higher than the lower surface of the magnetic body (31) or may be at the same height as the lower surface of the magnetic body (31). For example, the support member (64) and the magnetic body (33) may be positioned lower than the coupling portion (49) of the housing (210).

[0315] Referring to FIG. 12, for example, the first magnet unit (310A) and the second magnet unit (310B) may have the same shape and size. The length (L2) of the first magnet unit (310A) in the first axis direction may be smaller than the length (L1) of the first magnet unit (310A) in the second axis direction. In addition, the length of the second magnet unit (310B) in the second axis direction may be smaller than the second length of the second magnet unit (310B) in the first axis direction. The length of the first magnet unit (310A) in the optical axis direction may be smaller than the length (L2) of the first magnet unit (310A) (or the second magnet unit (310B)). In another embodiment, the length of the first magnet unit (310A) (or the second magnet unit (310B)) in the optical axis direction may be equal to or greater than the length (L2) of the first magnet unit (310A) (or the second magnet unit (310B)).

[0316] For example, the length (L1) of the first magnet unit (310A) (or the second magnet unit (310B)) may be smaller than the length of the tilting guide part (60) in the second direction (X-axis direction) or the third direction (Y-axis direction). For example, the length (L1) of the first magnet unit (310A) (or the second magnet unit (310B)) may be larger than the length (M1) between the outer surface and the inner surface of the tilting guide part (60). For example, M1 may be the shortest distance between the outer surface of the tilting guide part (60) and the opening (60A) of the tilting guide part (60). In other embodiments, L1 may be equal to or smaller than M1.

[0317] For example, the length (L1) of the first magnet unit (310A) (or the second magnet unit (310B)) may be smaller than the length of the opening (60A) of the tilting guide part (60) in the first or second axial direction. The length (L1) of the first magnet unit (310A) (or the second magnet unit (310B)) may be smaller than the length of the opening (60A) of the tilting guide part (60) in the second or third direction. In another embodiment, L1 may be greater than or equal to the length of the opening (60A) in the first or second axial direction. Alternatively, L1 may be greater than or equal to the length of the opening (60A) of the tilting guide part (60) in the second or third direction.

[0318] Referring to FIGS. 9A, 9B, and 12, the shortest separation distance (L3) between the first protrusions (65A, 65B) may be greater than the length (L1). The shortest separation distance (L4) between the second protrusions (66A, 66B) may be greater than the length (L1). For example, L3 and L4 may be the same. In other embodiments, L3 and L4 may be different. The description of L3 and L4 may also be applied or analogized to the first ball members (65A1, 65B1) and the second ball members (66A1, 66B1) of FIGS. 9C and 9D.

[0319] For example, the upper surface of the magnet (310) may be positioned lower than the upper surface of the coupling portion (49) of the housing (210). This is to secure sufficient space to avoid spatial interference between the magnet (310) and the lower surface of the sensor base (270). In another embodiment, the upper surface of the magnet (310) may be positioned higher than the upper surface of the coupling portion (49) of the housing (210). In yet another embodiment, the upper surface of the magnet (310) and the upper surface of the coupling portion (49) of the housing (210) may have the same height. For example, the upper surface of the magnet (310) may be positioned lower than the highest point of the first protrusion (65) of the tilting guide portion (60).

[0320] When viewed from above or in the direction of the optical axis, the protrusions (65A, 65B), the magnetic body (31), and the first magnet unit (310A) can overlap each other in the first axis direction. When viewed from above or in the direction of the optical axis, the protrusions (66A, 66B), the magnetic body (31), and the second magnet unit (310B) can overlap each other in the second axis direction.

[0321] When viewed from above or in the direction of the optical axis, the magnet (310) may not overlap with the magnetic body (31) in the second direction (X-axis direction) or the third direction (Y-axis direction).

[0322] In another embodiment, when viewed from above or in the direction of the optical axis, the magnet (310) may overlap with the magnetic body (31) in the second direction (X-axis direction) or the third direction (Y-axis direction).

[0323] Figure 15 is a perspective view of a camera device including a shield member (390).

[0324]

[0325] *Referring to FIG. 15, the camera device may include a shield member (390) that closes the opening (18) of the housing (210). The shield member (390) may be coupled or attached to the lower surface of the lower portion of the housing (210). The shield member (390) may be coupled to the housing (210) by an adhesive. For example, the shield member (390) may be in the form of an adhesive tape. The shield member (390) may also be expressed as a “cover,” a sealing member, or a “shield tape.”

[0326] In FIG. 15, the support member (64) may include a long side and a short side, and the support member (64) may be arranged such that the long side of the support member (64) is parallel to the second direction (X-axis direction) or the third direction. In other embodiments, the long side of the support member (64) may be arranged such that it intersects the second direction and the third direction. For example, in other embodiments, the long side of the support member (64) may be arranged such that it is parallel to the first axis or the second axis.

[0327] Fig. 16a shows the electromagnetic force (F1, F2) according to the interaction between the magnet units (310A, 310B) and the coil units (230A, 230B), and Fig. 16b shows the movement of the OIS moving part (100) due to the electromagnetic force of Fig. 16a. Fig. 16a shows the electromagnetic force when the first and second magnet units (310A, 310B) are two-pole magnets having an N pole and a S pole.

[0328] Referring to FIGS. 16A and 16B, the movement operation of the OIS moving unit by the OIS driving unit will be described. The OIS driving unit can tilt the OIS moving unit around a first axis perpendicular to the optical axis direction or a second axis intersecting the optical axis direction and the first axis. The OIS driving unit may include a coil (230) and a magnet (310). In addition, the OIS driving unit may include a position sensor (240).

[0329] For example, a first surface (e.g., an upper surface) of a first magnet unit (310A) facing or opposing the first coil unit (230A) in the optical axis direction and a first surface (e.g., an upper surface) of a second magnet unit (310B) facing or opposing the second coil unit (230B) in the optical axis direction may have opposite polarities. By making the first surface (e.g., an upper surface) of the first magnet unit (310A) and the first surface (e.g., an upper surface) of the second magnet unit (310B) have opposite polarities, the influence of the magnetic field of the first magnet unit (310A) on the second coil unit (230B) and the influence of the magnetic field of the second magnet unit on the first coil unit (230A) may cancel each other out, and magnetic field balancing may be implemented. As a result, the influence of unnecessary magnetic fields caused by two adjacent magnet units (310A, 310B) on the coil units (230A, 230B) can be suppressed or reduced, and the camera device (200) can improve the performance and reliability of OIS operation.

[0330] In addition, by making the first surface (e.g., the upper surface) of the first magnet unit (310A) and the first surface (e.g., the upper surface) of the second magnet unit (310B) have opposite polarities, the influence of the magnetic field of the first magnet unit (310A) on the second sensor (240B) and the influence of the magnetic field of the second magnet unit on the first sensor (240A) can be canceled out, and magnetic field balancing can be implemented. As a result, the influence of unnecessary magnetic fields originating from adjacent magnet units (310A, 310B) on the sensors (240A, 240B) can be suppressed or reduced, the reliability of the output of the sensors (240A, 240B) can be improved, and the performance and reliability of OIS operation can be improved.

[0331] Also, for example, the second surface (e.g., the lower surface) of the first magnet unit (310A) and the second surface (e.g., the lower surface) of the second magnet unit (310B) may have opposite polarities. The second surface (e.g., the lower surface) of the first magnet unit (310A) may be the opposite surface of the first surface (e.g., the upper surface) of the first magnet unit (310A) and may have a polarity that is opposite to the polarity of the first surface (e.g., the upper surface) of the first magnet unit (310A). The second surface (e.g., the lower surface) of the second magnet unit (310B) may be the opposite surface of the first surface (e.g., the upper surface) of the second magnet unit (310B) and may have a polarity that is opposite to the first surface (e.g., the upper surface) of the second magnet unit (310B). For example, the first surface of the first magnet unit (310A) may be an N pole (or S pole), and the first surface of the second magnet unit (310B) may be an S pole (or N pole).

[0332] A first electromagnetic force (F1) may be generated by the interaction between the first magnet unit (310A) and the first coil unit (230A). For example, the first electromagnetic force (F1) may be applied in the direction of the optical axis, for example, in the upward or downward direction. The OIS moving unit (100) may be tilted about the second axis (or the second protrusion (66)) by the first electromagnetic force (F1). For example, the OIS moving unit (100) may be tilted about the second axis by the first electromagnetic force (F1). Here, the second-axis tilting may mean that the OIS moving unit is tilted based on the second axis or that the OIS moving unit is rotated by a preset angle about the second axis as the rotation axis.

[0333] For example, the tilting guide part (60) can be tilted about the second axis (or the protrusions (66A, 66B) of the second protrusion (66)) by the first electromagnetic force (F1). For example, the tilting guide part (60) can be tilted about the second axis by the first electromagnetic force (F1). For example, in an embodiment where the protrusions (66A, 66B) are arranged in the first axis direction, the tilting guide part (60) can also be tilted about the first axis.

[0334] Referring to FIG. 4B, in order for the OIS moving unit to tilt with respect to the second axis (or the second protrusion (66) of the tilting guide unit (60)), a gap or space must exist between the tilting guide unit (60) and the OIS moving unit (e.g., the sensor base (270)) by the first protrusion (65) of the tilting guide unit (60). For example, a gap or space may exist between the upper surface (6A) of the tilting guide unit (60) and the OIS moving unit (e.g., the sensor base (270)) in which the tilting guide unit (60) can move. For example, the upper surface (6A) of the tilting guide unit (60) may be spaced apart from the OIS moving unit (e.g., the sensor base (270)) or the lower surface of the sensor base (270).

[0335] A second electromagnetic force (F2) can be generated by the interaction between the second magnet unit (310B) and the second coil unit (230B). For example, the second electromagnetic force (F2) can be applied in an upward or downward direction.

[0336] The OIS moving part can be tilted about the first axis (or the first protrusion (65)) by the second electromagnetic force (F2). For example, the OIS moving part can be tilted about the first axis by the second electromagnetic force (F2). Here, the first-axis tilting may mean that the OIS moving part is tilted based on the first axis or that the OIS moving part is rotated by a preset angle about the first axis as the rotation axis. For example, the tilting guide part (60) may come into contact with the fixed part (e.g., the housing (210)) by the first-axis or second-axis tilting, and at this time, the fixed part can act as a stopper to suppress the tilting of the OIS moving part.

[0337] Fig. 16c shows the arrangement of magnet units (310A, 310B) according to a modified example of Fig. 16a. Referring to Fig. 16c, a first surface (e.g., an upper surface) of a first magnet unit (310A) facing or opposite a first coil unit (230A) in the optical axis direction and a first surface (e.g., an upper surface) of a second magnet unit (310B) facing or opposite a second coil unit (230B) in the optical axis direction may have the same polarity. For example, the first surface of the first magnet unit (310A) and the first surface of the second magnet unit (310B) may be N poles (or S poles), and the second surface of the first magnet unit (310A) and the second surface of the second magnet unit (310B) may be S poles (or N poles).

[0338] FIG. 16d shows electromagnetic forces (F11, F12) according to the interaction between magnet units (310A1, 310B1) and coil units (230A, 230B) according to another embodiment.

[0339] Referring to FIG. 16d, the first magnet unit (310A1) may be a magnet that is divided or arranged into one N pole and one S pole in the first axis direction. The second magnet unit (310B1) may be a magnet that is divided or arranged into one N pole and one S pole in the second axis direction. For example, the first surface of the first magnet unit (310A1) may include an N pole and a S pole, and the first surface of the second magnet unit (310B1) may include an N pole and a S pole.

[0340] The first electromagnetic force (F11) resulting from the interaction between the first magnet unit (310A1) and the first coil unit (230A) can act in a direction different from the optical axis (e.g., in the first axis direction). The second electromagnetic force (F12) resulting from the interaction between the second magnet unit (310B1) and the second coil unit (230) can act in a direction different from the optical axis (e.g., in the second axis direction).

[0341] For example, the first electromagnetic force (F11) resulting from the interaction between the first magnet unit (310A1) and the first coil unit (230A) may act in a direction perpendicular to the optical axis. In addition, the second electromagnetic force (F12) resulting from the interaction between the second magnet unit (310B1) and the second coil unit (230B) may act in a direction perpendicular to the optical axis. For example, F11 and F12 may act in intersecting directions (e.g., perpendicular directions).

[0342] In FIG. 16d, the first pole of the first magnet unit (310A1) may be positioned closer to the tilting guide portion (60) than the second pole of the first magnet unit (310A1). In addition, the second pole of the second magnet unit (310B1) may be positioned closer to the tilting guide portion (60) than the first pole of the second magnet unit (310B1). Alternatively, the first pole of the first magnet unit (310A1) may be positioned on the inside, and the second pole of the first magnet unit (310A1) may be positioned on the outside. On the other hand, the first pole of the second magnet unit (310B1) may be positioned on the outside, and the second pole of the second magnet unit (310B1) may be positioned on the inside. For example, the first pole may be a N pole (or S pole), and the second pole may be a S pole (or N pole). In another embodiment, the first magnet unit (310A1) and the second magnet unit (310B1) may be arranged so that their opposite polarities are closer to the tilting guide portion (60). The description of the magnetic field balancing of the embodiment of FIG. 16A may be applied or analogized to the embodiment of FIG. 16D.

[0343] In another embodiment, the first magnet unit (310A1) and the second magnet unit (310B1) may be arranged so that the same polarity (e.g., N pole or S pole) is closer to the tilting guide portion (60).

[0344] The OIS moving part can be tilted about the second axis (or the second protrusion (66)) by the first electromagnetic force (F11). For example, the OIS moving part can be tilted about the second axis by the first electromagnetic force (F11). The OIS moving part can be tilted about the first axis (or the first protrusion (65)) by the second electromagnetic force (F12). For example, the OIS moving part can be tilted about the first axis by the second electromagnetic force (F12).

[0345] In FIG. 16a, FIG. 16c, and FIG. 16d, the yoke (380) can serve to increase the electromagnetic force (F1, F2, F11, F12) (or driving force).

[0346] In FIGS. 16A to 16D, the OIS moving part can be tilted based on the first axis or the second axis in the diagonal direction by the magnet units (310A, 310B), the coil units (230A, 230B), and the tilting guide part (60). In another embodiment, the arrangement of the magnet units (310A, 310B) and the coil units (230A, 230B), and the arrangement of the axes according to the protrusions (65, 66) of the tilting guide part can be changed to enable X-axis tilting or Y-axis tilting.

[0347] In a camera device (hereinafter referred to as "Comparative Example 1") in which the image sensor is fixed and the lens is moved in a direction perpendicular to the optical axis for image stabilization or shake correction, image distortion may occur. In addition, in a camera device (hereinafter referred to as "Comparative Example 2") in which the lens is fixed but the image sensor is moved or tilted for image stabilization or shake correction, image distortion may occur at the edge or corner of the image sensor. In Comparative Examples 1 and 2, since the image sensor and the lens are separated and only one of the image sensor and the lens is moved or tilted, image distortion may occur during image stabilization, and it may be difficult to correct for high-angle shake.

[0348] In an embodiment, for image stabilization, the OIS driving unit can tilt the OIS moving unit (100) based on the first axis or the second axis or rotate it within a preset angle range. In an embodiment, since the OIS moving unit (100) includes a lens module (400) and an image sensor (810), when the OIS is driven, the tilting direction (or rotation direction) and the tilting angle (or rotation angle) of the lens module (400, e.g., a lens or lens module) (or lens holder (110)) may be the same as or nearly the same as the tilting direction (or rotation direction) and the tilting angle (or rotation angle) of the image sensor (810).

[0349] In the embodiment, when OIS is driven, the lens module (400) (or lens holder (110)) and the image sensor (810) tilt or rotate together, so that there is no image distortion and 100% image resolution can be obtained, and high-angle shake correction or shake correction can be possible.

[0350] In addition, since the OIS moving part including the lens module (400) (or lens holder (110)) and the image sensor (810) tilts or rotates in the embodiment, even if shake occurs in the camera device, image degradation does not occur in the center of the image sensor and the outer part of the image sensor (e.g., the corner or corner area of ​​the image sensor). Therefore, the embodiment can perform shake correction in a high-broadband. In addition, since the embodiment can perform image correction without mechanical distortion, the load received during image processing is less compared to Comparative Examples 1 and 2, so that current consumption can be reduced.

[0351] In addition, since in the embodiment, a tilting guide part (60) is used for tilting the OIS moving part, compared to an example that uses only a ball member or a shaft member, the OIS moving part can be tilted stably, precisely, and accurately, thereby improving the reliability of OIS operation.

[0352] In addition, in the embodiment, the power consumption required for driving the OIS can be reduced by the bending portions (804D, 804E) and the third portion (804C) of the substrate (804), which is a flexible substrate of the circuit board (800).

[0353] In addition, in the embodiment, since the tilting guide part (60) is placed within the mounting part (69) of the housing (210) and the joining part (49) of the housing (210) overlaps with the opening (60A) of the tilting guide part (60), the height or length in the optical axis direction of the camera device (200) can be reduced.

[0354] In addition, in the embodiment, since at least a part of the magnetic body (31) is placed within the opening (60A) of the tilting guide part (60), the separation distance between the magnetic body (31) and the magnetic body (33) can be reduced, and thus the repulsive force or holding force for supporting the OIS moving part can be increased, thereby enabling stable OIS operation.

[0355] In addition, in the embodiment, since the first magnet unit (310A) and the second magnet unit (310B), which are driving magnets for image stabilization, are arranged on the lower part (42) of the housing (210) rather than on the side parts (71A to 71D) of the housing (210), the thickness (or length in the direction perpendicular to the optical axis) of the side parts (71A to 71D) of the housing (210) can be reduced, and thus, the camera can be designed in the future so as to be able to mount a large-diameter lens.

[0356] Fig. 17a shows the first position of the OIS moving part (100), and Fig. 17b shows the second position of the OIS moving part (100).

[0357] Referring to FIGS. 16A, 17A, and 17B, the OIS moving unit (100) can be tilted about the second axis by a preset angle (θ1) based on the second axis by a force (F1) resulting from the interaction between the first magnet unit (310A) and the first coil unit (310A). That is, when the OIS moving unit (100) moves from the first position to the second position, both the image sensor (810) and the lens module (400) can be tilted simultaneously by the preset angle (θ1). In addition, when the OIS moving unit (100) moves from the first position to the second position, the tilting guide unit (60) can be tilted by the preset angle (θ1) together with the image sensor (810) and the lens module (400).

[0358] Figure 17c shows the third position of the OIS moving part (100).

[0359] Referring to FIG. 17c, the OIS moving unit (100) can be tilted along the first axis by a preset angle (θ2) based on the first axis by a force (F2) resulting from the interaction between the second magnet unit (310B) and the second coil unit (310B). For example, when the OIS moving unit (100) moves from the first position to the third position, both the image sensor (810) and the lens module (400) can be tilted simultaneously by the preset angle (θ2).

[0360] Since the image sensor (810) and the lens module (400) are simultaneously tilted together with respect to the first axis or the second axis by at least one of the forces (F1) and (F2), the embodiment can obtain 100% image resolution without image distortion, and high-angle shake correction or shake correction can be possible.

[0361] For example, when viewed from above or in the direction of the optical axis, the first axis may be a first diagonal direction of the OIS moving unit (100), and the second axis may be a second diagonal direction of the OIS moving unit (100). For example, the first diagonal direction of the OIS moving unit may be a first diagonal direction of any one of the lens holder (110), the sensor base (270), or the substrate (801) of the circuit board (900). In addition, the second diagonal direction of the OIS moving unit may be a second diagonal direction of any one of the lens holder (110), the sensor base (270), or the substrate (801) of the circuit board (900).

[0362] In another embodiment, when viewed from above or in the direction of the optical axis, the first axis may be a first diagonal direction of the fixing portion, and the second axis may be a second diagonal direction of the fixing portion. For example, the first diagonal direction of the fixing portion may be a first diagonal direction of the housing (210) or the cover member (300). Additionally, the second diagonal direction of the fixing portion may be a second diagonal direction of the housing (210) or the cover member (300).

[0363] For example, the first diagonal direction of the OIS moving unit (100) (or the fixed unit) may be a direction intersecting with the second direction (e.g., the X-axis direction) or the third direction, and the second diagonal direction of the OIS moving unit (100) (or the fixed unit) may be a direction intersecting with the second direction (e.g., the X-axis direction) or the third direction. The first diagonal direction of the OIS moving unit (100) and the second diagonal direction of the OIS moving unit (100) may intersect each other. For example, the first diagonal direction of the OIS moving unit (100) and the second diagonal direction of the OIS moving unit (100) may be perpendicular to each other.

[0364] In another embodiment, the first axis may be a first horizontal direction of the OIS moving part (100) (or fixed part), and the second axis may be a second horizontal direction of the OIS moving part (100) (or fixed part).

[0365] Fig. 18 shows another modified embodiment (200-1) of Fig. 14a.

[0366] Referring to FIG. 18, the camera device (200-1) may omit the magnetic body (33) in the camera device (200), and the support member (64-1) may serve as the omitted magnetic body (33). That is, the support member (64-1) may be a magnetic body. In FIG. 18, the support member (64-1) may be expressed by replacing it with a “magnetic body.”

[0367] The magnetic body (64-1) can be coupled with the sensor base (270). For example, the magnetic body (64-1) can be coupled with the extension (217) of the sensor base (270). For example, the magnetic body (64-1) can be coupled with the extension (217) of the sensor base (270) by an adhesive. Or, for example, the magnetic body (64-1) can be coupled with the extension (217) of the sensor base (270) by a pin-hole coupling or a male-female coupling. For example, one of the extension (217) and the magnetic body (64-1) can be a pin (or hole), and the other of the extension (217) and the magnetic body (64-1) can be a hole (or pin).

[0368] The description of the magnetic body (33) and the description of the support member (64) can be applied or analogized to the magnetic body (64-1) of Fig. 18. A repulsive force can be applied between the magnetic body (31) and the magnetic body (64-1), and the magnetic body (31) and the magnetic body (64-1) can play a role in supporting the OIS moving part.

[0369] In the embodiment of Fig. 18, the magnetic body (33) is omitted and the support member (64-1) takes the place of the magnetic body, so that, compared to the embodiment of Fig. 14a, the same performance as the embodiment of Fig. 14a can be performed while reducing the number of parts and reducing the weight of the camera device.

[0370] Fig. 19 shows the arrangement of an OIS driving unit according to another embodiment.

The mounting portion (242) may be in the form of a groove or through hole formed on the side of the housing (210).

[0392] The camera device (200) may further include a circuit board (190) disposed on a fixing member (e.g., a housing (210). The coil (230) may be disposed on or coupled to the circuit board (190). The coil (230) may be conductively or electrically connected to the circuit board (190). The circuit board (190) may include a first substrate (191) disposed on one of two adjacent sides (e.g., 71B, 71C) of the housing (210) and a second substrate (192) disposed on the other of the two adjacent sides (e.g., 71B, 71C) of the housing (210).

The position sensor (240) may be placed or mounted on the circuit board (190) and may be conductively or electrically connected to the circuit board (190).

[0396] In another embodiment, the OIS driving unit may include a control unit (835) disposed on a circuit board (190). The control unit (835) may be electrically or conductively connected to the circuit board (190). For example, the control unit (835) may be a driver IC. The control unit (835) may be disposed on either the first substrate (191) or the second substrate (9192). The control unit (835) may be electrically or conductively connected to the coil (230-3). The control unit (835) may supply a driving signal to the coil (230-3). The control unit (835) may be electrically connected to the coil units (230A, 230B), supply a first driving signal to the first coil unit (230A), and supply a second driving signal to the second coil unit (230B).

[0397] The control unit (835) may be conductively or electrically connected to the position sensor (240).

[0398] The control unit (835) can supply power or a driving signal to the position sensor (240). For example, the control unit (835) can supply power or a driving signal to each of the first sensor (240A) and the second sensor (240B). The control unit (835) can receive an output signal of the position sensor (240) and control a driving signal (e.g., a driving current) supplied to the coil (230) using the output signal of the position sensor (240). For example, the control unit (835) can receive an output signal of the first sensor (240A) and control a first driving signal (e.g., a first driving current) supplied to the first coil unit (230A) using the output signal of the first sensor (240A). Additionally, the control unit (835) can receive an output signal of the second sensor (240B) and control a second driving signal (e.g., a second driving current) supplied to the second coil unit (230B) using the output signal of the second sensor (240B).

[0399] The circuit board (190) may include a terminal portion (not shown) for electrical connection with the outside. The terminal portion may include a plurality of terminals. For example, the plurality of terminals of the circuit board (190) may be exposed from the side plate (302) of the cover member (300). At least one of the plurality of terminals may be conductively or electrically connected to the control unit (835).

[0400] In another embodiment, the circuit board (190) may be electrically connected to the circuit board (800) and may be electrically connected to the outside through a connector (805) of the circuit board (800).

[0401] In another embodiment, the positions of the magnet (310) and the coil (230) in FIGS. 6 and 19 may be interchanged. That is, the magnet (310) may be placed on the moving part (100) (e.g., the sensor base (270)), and the coil (230) may be placed on the fixed part (e.g., the housing (210)). In addition, the yoke of FIG. 16A may be placed on the sensor base (270). In this case, the magnet and the coil may face each other or overlap in the optical axis direction. For example, the coil (230) may be placed on the mounting part (141) of the housing (140). In this case, the mounting part (141) may be a through hole that passes through the lower part (42) of the housing (140). Additionally, another embodiment may include a "circuit board" disposed under the housing (210) separately from the circuit board (800) and conductively or electrically connected to the second coil (230). The position sensor (240) may be disposed or coupled to the circuit board disposed under the housing (210). Additionally, in another embodiment, a control unit, which functions similarly to the control unit (835) of FIG. 19, may be disposed on the circuit board disposed under the housing (210).

[0402] In FIGS. 1 to 21, the tilting guide part (60) is brought into close contact with the OIS moving part and the fixed part by the repulsive force acting between the magnetic body (33) and the magnetic body (31), but in other embodiments, the tilting guide part (60) may be pressed against the moving part by the attractive force between the two magnetic bodies.

[0403] FIG. 22a is a cross-sectional view taken along the GH direction of FIG. 4D of a camera device according to another embodiment, and FIG. 22b is a cross-sectional view taken along the IJ direction of FIG. 4e of the camera device of FIG. 22a.

[0404] In the embodiments of FIGS. 22a and 22b, the tilting guide part (60) can be brought into close contact with the OIS moving part and fixed part by the attractive force between two magnetic bodies (31-1, 33-1).

[0405] The sensor base (270-1) according to the embodiment of FIGS. 22a and 22b may have a structure in which the extension portion (217) of the sensor base (270) is omitted. The magnetic body (33-1) may be placed on the sensor base (270-1). For example, the magnetic body (33-1) may be placed on the lower surface of the sensor base (270-1). A groove may be formed on the lower surface of the sensor base (270-1) for placing the magnetic body (33-1).

[0406] The housing (210-1) may omit the hole (18) of FIG. 10a. The magnetic body (31-1) may be placed in the housing (210-1) so as to correspond to, face, or overlap with the magnetic body (33-1) in the optical axis direction. The magnetic body (31-1) may be placed in the protrusion (49) of the housing (210-1). The magnetic bodies (31-1) and (33-1) may be placed so that they exert an attractive force on each other. The magnetic bodies (31-1, 33-1) may be made of a magnetic material. Or, for example, the magnetic bodies (31-1, 33-1) may be made of a magnetic metal material. Or, for example, the magnetic bodies (31-1, 33-1) may be magnets. The magnetic bodies (31-1, 33-1) may also be expressed as a "yoke". For example, each of the magnetic body (31-1) and the magnetic body (33-1) may be a magnet, and a first surface (e.g., a lower surface) of the magnetic body (33-1) may face a first surface (e.g., a top surface) of the magnetic body (31-1) in the direction of the optical axis. The first surface (e.g., a lower surface) of the magnetic body (33-1) and the first surface (e.g., a top surface) of the magnetic body (31-1) may have opposite polarities. For example, the first surface (e.g., a lower surface) of the magnetic body (33-1) may be a N pole (or a S pole), and the first surface (e.g., a top surface) of the magnetic body (31-1) may be a S pole (or a N pole). Additionally, the second surface (e.g., upper surface) of the magnetic body (33-1) and the second surface (e.g., lower surface) of the magnetic body (31-1) may have opposite polarities. The second surface of the magnetic body (33-1) may be the opposite surface of the first surface of the magnetic body (33-1), and the second surface of the magnetic body (31-1) may be the opposite surface of the first surface of the magnetic body (31-1).

[0407] The force structure of the two magnetic bodies (31-1, 33-1) of FIGS. 22a and 22b can be applied or analogized to the embodiments described in FIGS. 1 to 21.

[0408] In another embodiment, instead of the attractive force structure between the magnetic bodies of FIGS. 22a and 22b, the tilting guide part (60) may be brought into close contact with the OIS moving part and the fixed part by an elastic member connecting the OIS moving part and the fixed part. For example, the elastic member may be a coil spring or a plate spring. By the restoring force of the elastic member, the tilting guide part (60) may be pressed by the OIS moving part and the fixed part, and may be brought into close contact with the OIS moving part and the fixed part.

[0409] For camera devices installed or positioned within a vehicle, the vehicle's interior space is limited. This means that the actual focusing range within the vehicle is short. Therefore, the embodiment is a fixed-focus camera device. Even without an autofocus function, the embodiment can achieve sufficient subject clarity within the vehicle with a fixed focus.

[0410] The embodiment does not include a configuration for an autofocus function. Here, the configuration for the autofocus function may include a coil and a magnet. In addition, the configuration for the autofocus function may include a separate holder (or housing) for arranging either the coil or the magnet. In addition, the configuration for the autofocus function may include a cloud member (or elastic member) arranged between the lens holder (110) and the holder (or housing) to support the lens holder (110) with respect to the holder (or housing).

[0411] Since the embodiment does not include a configuration for an autofocus function, manufacturing costs can be reduced. Furthermore, since the embodiment does not include a configuration for an autofocus function, the length of the camera device in the direction of the optical axis or the length in the direction perpendicular to the direction of the optical axis of the camera device can be reduced.

[0412] In addition, in the embodiment, the size of the lens module may not be restricted by the space in which the configuration for the autofocus function is arranged, and thus the size of the lens module and the corresponding image sensor may be increased, and thus a high-resolution image may be implemented.
