[0001] The present invention relates to a camera actuator.

[0002] A camera is a device that captures images or videos of a subject, and is installed in portable devices, drones, vehicles, etc.

[0003] A camera device or camera actuator may have an image stabilization (IS) function to correct or prevent shaking caused by the user's movement to improve the quality of the image, an auto focusing (AF) function to automatically adjust the distance between the image sensor and the lens to align the focal length of the lens, and a zooming function to increase or decrease the magnification of a distant subject and take pictures using a zoom lens.

[0082] First, referring to FIGS. 1 and 2 for a general description of a camera module (10) according to an embodiment of the present invention, the camera module (10) according to an embodiment of the present invention may be composed of a cover (3000), a first camera actuator (1000), a second camera actuator (2000), and a circuit board (4000).

[0083] Here, the first camera actuator (1000) may be used interchangeably as the first actuator, and the second camera actuator (2000) may be used interchangeably as the second actuator.

[0084] Additionally, the cover (3000) covers the first camera actuator (1000) and the second camera actuator (2000), and the bonding force between the first camera actuator (1000) and the second camera actuator (2000) can be improved by the cover (3000).

[0085] Furthermore, the cover (3000) may be made of a material that blocks electromagnetic waves. Accordingly, the first camera actuator (1000) and the second camera actuator (2000) within the cover (3000) can be easily protected.

[0086] And the first camera actuator (1000) may be an OIS (Optical Image Stabilizer) actuator. For example, the first camera actuator (1000) may tilt the optical member (20) in a direction perpendicular to the optical axis (axis of refracted light).

[0087] Additionally, the first camera actuator (1000) may include a fixed focal length lens arranged in a predetermined barrel (not shown).

[0088] Here, a fixed focal length lens may also be referred to as a "single focal length lens" or "single lens".

[0089] Meanwhile, the first camera actuator (1000) can change the path of light.

[0090] For example, the first camera actuator (100) can change the optical path vertically through an internal optical element (20) (e.g., a prism or mirror).

[0091] For example, the optical member (20) can change light from a second direction to a first direction.

[0092] By this configuration, even if the thickness of the mobile terminal is reduced, a lens configuration larger than the thickness of the mobile terminal can be placed within the mobile terminal through a change in the optical path, thereby performing magnification, auto-focusing (AF), zoom, and OIS functions.

[0093] However, it is not limited thereto, and the first camera actuator (1000) can change the optical path vertically or at a predetermined angle multiple times.

[0094] Meanwhile, the second camera actuator (2000) may be placed at the rear end of the first camera actuator (1000). In addition, the second camera actuator (2000) may be coupled with the first camera actuator (1000).

[0095] And the coupling between the first camera actuator (1000) and the second camera actuator (2000) can be achieved in various ways. In addition, the second camera actuator (2000) can be a zoom actuator or an AF (Auto Focus) actuator.

[0096] For example, the second camera actuator (2000) supports one or more lenses and can perform an auto-focusing function or a zoom function by moving the lenses according to a control signal from a predetermined control unit.

[0097] And one or more lenses can move independently or individually along the first direction.

[0098] Meanwhile, the circuit board (4000) may be placed behind the second camera actuator (2000) in the first direction. Here, the circuit board (4000) may be electrically connected to the second camera actuator (2000) and the first camera actuator (1000). In addition, there may be a plurality of circuit boards (4000).

[0099] The camera module (10) according to the embodiment may be composed of a single or multiple camera modules (10). For example, the multiple camera modules (10) may include a first camera module and a second camera module.

[0100] And a single camera module (10) may include a single or multiple actuators.

[0101] For example, a single camera module (10) may include a first camera actuator (1000) and a second camera actuator (2000). In addition, the camera module (10) may be used interchangeably with various terms such as camera device, imaging device, etc.

[0102] And the camera module (10) is placed in a predetermined case (not shown) and may include an actuator (not shown) that can drive the lens unit. The actuator may be a voice coil motor, a micro actuator, a silicon actuator, etc., and may be applied in various ways such as an electrostatic method, a thermal method, a bimorph method, an electrostatic force method, etc., but is not limited thereto. In addition, in this specification, the camera actuator (1000, 2000) may be referred to as an actuator, etc. This will be described in more detail with reference to the drawings to be described later.

[0103] In addition, a camera module (10) composed of a plurality of camera modules (10) can be mounted in various electronic devices such as mobile terminals. Furthermore, the actuator may be a device that moves or tilts a lens or an optical member (20). However, the following description will be made with the concept that the actuator includes a lens or an optical member (20). Furthermore, the actuator may be called a 'lens transport device', 'lens transport device', 'optical member transport device', 'optical member moving device', etc.

[0104] A camera module (10) according to an embodiment may include a first camera actuator (1000) having an OIS function and a second camera actuator (2000) having a zooming function and an AF function.

[0105] Light can be incident into the camera module or the first camera actuator (1000) through an opening area located on the upper surface of the first camera actuator (1000). That is, the light is incident into the interior of the first camera actuator (1000) along the first direction, and the optical path can be changed vertically through the optical member (20).

[0106] And the light can pass through the second camera actuator (2000) and be incident on the image sensor located at one end of the second camera actuator (2000) (PATH). In addition, in the present specification, the first direction and the vertical direction may correspond to the second direction, and the horizontal direction may correspond to the third direction.

[0107] Additionally, in the present specification, the inner side may be a direction toward the first camera actuator (1000) from the cover (3000), and the outer side may be a direction opposite to the inner side. For example, the first camera actuator (1000) and the second camera actuator (2000) may be located inside the cover (3000), and the cover (3000) may be located outside the first camera actuator (1000) or the second camera actuator (2000).

[0108] The camera module (10) according to the embodiment can improve the spatial limitations of the first camera actuator (1000) and the second camera actuator (2000) by changing the path of light. The camera module (10) according to the embodiment can expand the optical path while minimizing the thickness of the camera module (10) in response to the change in the path of light. Furthermore, it should be understood that the second camera actuator (2000) can provide a high range of magnification by controlling the focus, etc. in the expanded optical path.

[0109] In addition, the camera module (10) according to the embodiment can implement OIS by controlling the optical path through the first camera actuator (1000), thereby minimizing the occurrence of decenter or tilt phenomena and producing the best optical characteristics.

[0110] Furthermore, the second camera actuator (2000) may include an optical system and a lens driving unit. For example, the second camera actuator (2000) may be configured with at least one of a first lens assembly (2310), a second lens assembly (2350), and a third lens assembly (2200). In addition, the second camera actuator (2000) may include coils (2620, 2640) and magnets (2330, 2360) to perform a high-magnification zooming function and an autofocus function. This will be described in more detail with reference to the drawings to be described later.

[0111] For example, the first lens assembly (2310) and the second lens assembly (2350) may be moving lenses that move through coils (2620, 2640), magnets (2330, 2360) and guide pins, and the third lens assembly (2200) may be a fixed lens, but is not limited thereto. For example, the third lens assembly (2200) may perform the function of a focalizer that focuses light at a specific location, and the distance to the subject or the image distance may change significantly depending on the movement of the first lens assembly (2310), resulting in a large change in magnification. In addition, the first lens assembly (2310), which is a variable magnification, may play an important role in the change in the focal length or magnification of the optical system.

[0112] Meanwhile, the point of interest formed by the first lens assembly (2310), which is a variable lens, may differ slightly depending on the position. Accordingly, the second lens assembly (2350) may perform a position compensation function for the image formed by the variable lens. For example, the second lens assembly (2350) may perform a compensator function that accurately forms the point of interest formed by the first lens assembly (2310), which is a variable lens, at the actual image sensor position.

[0113] And the first lens assembly (2310) and the second lens assembly (2350) can be driven by electromagnetic force due to the interaction of coils (2620, 2640) and magnets (2330, 2360). In addition, the first lens assembly (2310) and the second lens assembly (2350) can move along the first direction. And the first lens assembly (2310) and the second lens assembly (2350) can move in the first direction independently or dependently.

[0114] Furthermore, the third lens assembly (2200) may be positioned at the front end of the first lens assembly (2310) or the rear end of the second lens assembly (2350). That is, the third lens assembly (2350) may be positioned adjacent to the first camera actuator (1000) or adjacent to the image sensor. In addition, the third lens assembly (2200) may be in a fixed state.

[0115] In the present invention, the first lens assembly (2310) and the second lens assembly (2350) can move along the first direction. And the third lens assembly (2200) can be located at the front end of the first lens assembly (2310) or the rear end of the second lens assembly (2350). And the third lens assembly (2200) may not move in the first direction. That is, the third lens assembly (2200) can be a fixed lens assembly (2200). In addition, the first and second lens assemblies (2310, 2350) can be movable lens assemblies (2300).

[0116] Meanwhile, when an actuator for OIS and an actuator for AF / Zoom are arranged according to an embodiment of the present invention, magnetic interference with the magnet for AF / Zoom can be prevented when the OIS is driven. Since the magnet of the first camera actuator (1000) is arranged separately from the second camera actuator (2000), magnetic interference between the first camera actuator (1000) and the second camera actuator (2000) can be prevented. In this specification, OIS can be used interchangeably with terms such as image stabilization, optical image stabilization, optical image correction, and shake correction.

[0117] Although the camera module (10) according to the embodiment of the present invention has been described in general, this is an exemplary description of the camera module (10) according to the embodiment of the present invention and a description to help with general understanding, and a more detailed understanding can be obtained through the description of the first camera actuator (1000) and the second camera actuator (2000) to be described later.

[0118] First, as illustrated in FIG. 3, a first camera actuator (1000) according to an embodiment of the present invention may include a first housing (1100), a mover (1200) disposed within the first housing (1100), a support member (1300) disposed on one side of the mover (1200), a hinge member (1410, 1420, 1500) disposed between the mover (1200) and the support member (1300), and a driving member.

[0119] Here, the first housing (1100) forms the exterior of the first camera actuator (1000), and a plurality of holes are formed, and a driving unit or a Drive IC may be placed in each of the plurality of holes.

[0120] In addition, the mover (1200) is placed inside the first housing (1100), and can be placed to overlap with the hole inside the first housing (1100), and the mover (1200) can tilt and move in response to the inclination according to the electrical interaction of the driving parts.

[0121] In addition, the mover (1200) is provided with a mounting space where the optical member (20) is positioned, and the optical member (20) can change the path of the incident light to a first direction toward the second camera actuator (2000). This allows the camera module to be miniaturized.

[0122] Here, the driving unit may include a first driving unit, a second driving unit, and a third driving unit, and the first driving unit may include a first-first coil (1611), a first-first magnet (1612), and a first-first hall sensor (1613), the second driving unit may include a first-second coil (1621), a first-second magnet (1622), and a first-second hall sensor (1623), and the third driving unit may include a first-third coil (1631), a first-third magnet (1632), and a third hall sensor (1633).

[0123] At this time, the first driving unit may be arranged in a placement space formed on one side of the mover (1200) by penetrating a hole in the side of the first housing (1100), the second driving unit may be arranged in a placement space formed on the other side of the mover (1200) in a direction opposite to the first driving unit on the side of the first housing (1100), and the third driving unit may be arranged in a placement space formed on the bottom surface of the mover (1200) by penetrating a hole formed on the bottom surface of the first housing (1100).

[0124] Meanwhile, before explaining the first camera actuator (1000) according to an embodiment of the present invention, let us define the direction for a more detailed explanation. The first direction means that the light is incident on the first camera actuator (1000) and the optical path is changed by the optical member (20) from the first camera actuator (1000) to the second camera actuator (2000), so the first direction is parallel to the optical axis of the refracted light, and means the direction from the first camera actuator (1000) to the second camera actuator (2000), and may mean both directions including the direction from the lower left to the upper right and the direction from the upper right to the lower left with reference to FIG. 3.

[0125] In addition, the second direction may mean a direction perpendicular to the optical axis and in which light is incident on the first camera actuator (1000), and may mean both directions including a direction from the upper side to the lower side and a direction from the lower side to the upper side with reference to FIG. 3.

[0126] Additionally, the third direction may mean a direction perpendicular to the first and second directions, and may mean both directions including a direction from the upper left to the lower right and a direction from the lower right to the upper left with reference to FIG. 3.

[0127] In explanation based on this, the first housing (1100) is formed with a pair of holes penetrating in the second direction and a pair of holes penetrating in the third direction, and the mover (1200) is formed with a placement space that is sunken in the second direction and a placement space that is sunken in the third direction corresponding to the holes of the first housing (1100), and a third driving unit is arranged in the placement space that is sunken in the second direction, and a first driving unit and a second driving unit can be arranged in the placement space that is sunken in the third direction.

[0128] Meanwhile, the support member (1300) is arranged on one side of the first housing (1100) in the first direction, is arranged adjacent to the mover (1200), and may be arranged relatively farther from the second camera actuator (2000) than the mover (1200) based on the first direction.

[0129] Here, a hinge part (1410, 1420, 1500) is arranged between the support part (1300) and the mover (1200), and the hinge part (1410, 1420, 1500) includes a first bracket (1410), a second bracket (1420), and a first frame (1500), and the first bracket (1410) is arranged between the mover (1200) and the first frame (1500), the first frame (1500) is arranged between the mover (1200) and the support part (1300), and the second bracket (1420) may be arranged relatively farther from the second camera actuator (2000) than the support part (1300).

[0130] To explain this in more detail, as illustrated in FIG. 4, the first frame (1500) includes a body portion (1530), a first-first extension portion (1510), and a first-second extension portion (1520). The first-first extension portions (1510) are arranged in pairs spaced apart from each other with a first bracket (1410) interposed therebetween, the first-second extension portions (1520) are arranged in pairs spaced apart from each other with a second bracket (1420) interposed therebetween, and the body portion (1530) can connect the first-first extension portion (1510) and the first-second extension portion (1520).

[0131] That is, the 1-1 extension part (1510) is connected to the 1st bracket (1410), the 1-2 extension part (1520) is connected to the 2nd bracket (1420), and the body part (1530) can connect the 1-1 extension part (1510) and the 1-2 extension part (1520) to connect the 1st bracket (1410) and the 2nd bracket (1420).

[0132] In addition, the first-first extension portion (1510) may extend from both ends of the body portion (1530) in the second direction in a direction toward the mover (1200), and the first-second extension portion (1520) may extend from both ends of the body portion (1530) in the third direction in a direction toward the support portion (1300). In other words, the first-first extension portion (1510) may be formed by bending from both ends of the body portion (1530) in the second direction in a direction toward the mover (1200), and the first-second extension portion (1520) may be formed by bending from both ends of the body portion (1530) in the third direction in a direction toward the support portion (1300).

[0133] At this time, a pair of 1-1 extension portions (1510) are extended so that the distance between the ends in the direction away from the body portion (1530) in the first direction becomes closer to each other, and when viewed from the side, the distance between the end extending from the body portion (1530) and the end relatively far from the body portion (1530) may be different. That is, the distance between the pair of 1-1 extension portions (1510) in the direction toward the first bracket (1410) becomes closer to each other, so that the pair can be more effectively fixed to the first bracket (1410).

[0134] In addition, a pair of first-second extension portions (1520) extend in a direction such that the distance between the ends becomes closer to each other in the direction away from the body portion (1530) in the first direction, and when viewed from above and below, the distance between the ends extending from the body portion (1530) and the ends relatively far from the body portion (1530) may be different. That is, the distance between a pair of first-second extension portions (1520) in the direction toward the second bracket (1420) becomes closer to each other so that the first-second extension portions (1520) can be more effectively fixed to the second bracket (1420).

[0135] Meanwhile, each of a pair of first-first extensions (1510) may be formed with a first convex portion (1511) that protrudes in a direction away from the first bracket (1410), and each of a pair of first-second extensions (1520) may be formed with a second convex portion (1521) that protrudes in a direction away from the second bracket (1420).

[0136] At this time, a first insertion portion (1413) inserted into a first convex portion (1511) is formed in the first bracket (1410), and a second insertion portion (1423) inserted into a second convex portion (1521) is formed in the second bracket (1420). The first insertion portion (1413) and the second insertion portion (1423) described above will be described in more detail with reference to the drawings to be described later.

[0137] Here, the first-first extension portion (1510) may extend from both ends in the second direction with respect to the body portion (1530) toward the mover (1200) in the first direction, and the first-second extension portion (1520) may extend from both ends in the third direction with respect to the body portion (1530) toward the support portion (1300) in the first direction.

[0138] Meanwhile, referring to FIG. 5 to explain the first bracket (1410) and the first-first extension (1510) in more detail, as illustrated in FIG. 5, the mover (1200) is formed with a support (1300), more specifically, a first protrusion (1210) extending from the body of the mover (1200) toward the body (1530), and the first bracket (1410) can be positioned at the first protrusion (1210). More specifically, the first protrusion (1210) is formed with a first step (1220) formed in a stepwise manner in the second direction, and the first bracket (1410) can be positioned at the first step (1220).

[0139] To explain this in detail, the first protrusion (1210) protrudes in a first direction from the body of the mover (1200), but protrudes in a direction toward the support (1300) in the first direction, and the first step (1220) is formed in a pair so as to be sunken in a second direction on one surface of the first protrusion (1210), and the first bracket (1410) can be positioned so that a portion overlaps the first step (1220) in the second direction.

[0140] That is, the first bracket (1410) is provided with a first bent portion (1411) and a second bent portion (1415) that are bent in correspondence with the bending shape of the body portion (1530) and the first-first extension portion (1510), and is divided into a second-first body portion (1412) that connects the first bent portion (1411) and the second bent portion (1415), and the first bent portion (1411) and the second bent portion (1415) are each arranged in the first step portion (1220), and are arranged to overlap with the first step portion (1220) in the second direction, and the second-first body portion (1412) can be arranged to overlap with the first protrusion (1210) in the first direction.

[0141] Here, to describe the first step portion (1220) in more detail, the first step portion (1200) may refer to an area formed stepwise on the upper surface of the first protrusion portion (1210) in the second direction and an area formed stepwise on the lower surface of the first protrusion portion (1210) in the second direction, respectively. That is, a pair of first step portions (1220) may be formed on one side and the other side of the first protrusion portion (1210) in the second direction, respectively.

[0142] At this time, a body that is not indicated by a drawing number in the detailed description of the present invention may mean a part or the whole that forms the appearance of the mentioned configuration. For example, the first protrusion (1210) protruding from the body of the mover (1200) can be interpreted as the first protrusion (1210) protruding from the mover (1200), the upper body of the support (1300) is preferably understood to mean the upper part of the support (1300), and the lower body of the support (1300) is understood to mean the lower part of the support (1300). In addition, the body part (1530) indicated by a drawing number in the description of the first camera actuator (1000) can be easily understood by referring to the drawings.

[0143] In addition, a first insertion portion (1413) inserted into the first convex portion (1511) is formed in the first bend portion (1411) and the second bend portion (1415), that is, in the area of ​​the first bracket (1410) that overlaps the first step portion (1220) in the second direction, and the first insertion portion (1413) can be formed in the first bend portion (1411) and the second bend portion (1415), respectively. In addition, an adhesive member can be provided between the first bend portion (1411) and the first step portion (1220) and between the second bend portion (1415) and the first step portion (1220) to fix the first bracket (1410).

[0144] That is, in a state where the first bracket (1410) is positioned on the first step portion (1220), the first frame (1500) is arranged so that the first-first extension portion (1510) overlaps the first bracket (1410) and the first step portion (1220) in the second direction, and the pair of first-first extension portions (1510) are arranged so that the distance between the ends becomes closer to each other in the direction away from the body portion (1530), so that the first insertion portion (1413) can be easily inserted into the inside of the first convex portion (1511), and the first insertion portion (1413) can be inserted into the inside of the first convex portion (1511) and fix the body portion (1530). In addition, the first insertion portion (1413) protrudes to have a convex hemispherical shape and comes into contact with the inner surface of the first convex portion (1511), and the mover (1200) can be tilted based on the first insertion portion (1413).

[0145] To explain this in more detail, as illustrated in FIG. 6, a first insertion portion (1413) is inserted into the inside of the first convex portion (1511), and a part of the inner surface of the first convex portion (1511) and the outer surface of the first insertion portion (1413) come into contact with each other, and the mover (1200) tilts based on the first convex portion (1511) and the first insertion portion (1413), which can guide the mover (1200) to tilt in the first direction based on the second direction.

[0146] In addition, the 2-1 body part (1412) of the 1st bracket (1410) may be spaced apart from the body part (1530) by a predetermined distance so as to have a first gap in the first direction, and the angle at which the mover (1200) tilts may be limited depending on the distance between the 2-1 body part (1412) of the 1st bracket (1410) and the body part (1530).

[0147] For example, if the 2-1 body part (1412) and the body part (1530) of the 1st bracket (1410) are in contact with each other, if the mover (1200) is tilted, the first protrusion (1210) is caught on the body part (1530), and since the mover (1200) cannot be tilted by the body part (1530), it may be desirable for the 2-1 body part (1412) and the body part (1530) to be spaced apart from each other.

[0148] In addition, the mover (1200) may be formed with a sunken space (1230) that is sunken in the first direction, and a first protrusion (1210) may be formed by protruding in the first direction on one side of the sunken space (1230). That is, the first protrusion (1210) overlaps the body of the mover (1200) in the first direction, which may have the advantage of moving the center of gravity of the mover (1200) toward the first frame (1500) and tilting the mover (1200) with less power.

[0149] For example, if the center of gravity is located relatively far from the first protrusion (1210), the distance from the tilting axis becomes relatively far, so the applied force becomes large. However, if the first protrusion (1210) is located in the sunken space (1230) as in the present invention, and the first protrusion (1210) overlaps the body of the mover (1200) in the first direction, the center of gravity moves to the space where the hinge portion (1410, 420, 500) is located relatively close to the axis, so there may be an advantage of tilting the mover (1200) with less power.

[0150] Meanwhile, referring to FIG. 7 to explain the second bracket (1420) and the first-second extension (1520) in more detail, as illustrated in FIG. 7, the support (1300) may be formed with a wall (1310) extending from the center of the body in a first direction, and the second bracket (1420) may be positioned on the wall (1310). More specifically, the wall (1310) may be formed with a second step (1320) formed in a stepwise manner in the first direction, and the second bracket (1420) may be positioned on the second step (1320).

[0151] At this time, to describe the wall portion (1310) in detail, the body of the support portion (1300) is formed with an opening portion that opens in the first direction, and the opening portion of the support portion (1300) and the mover (1200) are formed to overlap in the first direction, so that the body of the support portion (1300) can have a form in which the opening portion is formed on the inside.

[0152] Here, the wall portion (1310) is formed in a shape extending from the center of the body of the support portion (1300) in the third direction toward the second direction to connect the upper body and the lower body, and it may be preferable that the wall portion (1310) be arranged at a position overlapping with the mover (1200), the first protrusion (1210), the first bracket (1410), the second bracket (1420), and the body portion (1530) in the first direction.

[0153] That is, it is preferable to extend from the body center of the support (1300) in the second direction, but as described above, the wall (1310) is arranged at a position overlapping the mover (1200) and the first protrusion (1210), the first bracket (1410), the second bracket (1420), and the body (1530) in the first direction, and may be arranged at a position that is a predetermined distance from the body center of the support (1300) in the third direction depending on the manufacturing tolerance.

[0154] This is an illustrative description of one example and may not necessarily be limited to it.

[0155] Meanwhile, the wall portion (1310) extends in the first direction from the center of the body of the third-direction support portion (1300) as described above, the second step portion (1320) is formed to be sunken in the first direction on one surface of the wall portion (1310), and the second bracket (1420) can be positioned so that a portion overlaps the second step portion (1320) in the third direction.

[0156] However, unlike the pair of first steps (1220), the second step portion (1320) may include a region that is sunken in the first direction on one side of the wall portion (1310) and a region that is sunken inwardly toward the wall portion (1310) in a third direction. In this case, the region that is sunken inwardly toward the wall portion (1310) in the third direction may be respectively positioned at the end of the region that is sunken in the first direction on one side of the wall portion (1310).

[0157] Here, the second bracket (1420) is provided with a third bent portion (1421) and a fourth bent portion (1425) that are bent in response to the bending shape of the body portion (1530) and the first-second extension portion (1520), and is divided into a second-second body portion (1422) that connects the third bent portion (1421) and the fourth bent portion (1425), and the third bent portion (1421) and the fourth bent portion (1425) are each arranged in an area that is sunken toward the inside of the wall portion (1310) in the third direction of the second step portion (1320), and the second-second body portion (1422) is arranged in an area that is sunken in the first direction on one surface of the wall portion (1310), and the third bent portion (1421) and the fourth bent portion (1425) are arranged in the second direction. It is arranged to overlap with the wall portion (1310), and the second-second body portion (1422) can be arranged to overlap with the wall portion (1310) in the first direction.

[0158] In addition, a second insertion portion (1423) inserted into the second convex portion (1521) is formed in the third bend portion (1421) and the fourth bend portion (1425), that is, in the area of ​​the second bracket (1420) that overlaps the wall portion (1310) in the third direction, and the second insertion portion (1423) can be formed in the third bend portion (1421) and the fourth bend portion (1425), respectively. In addition, an adhesive member can be provided between the third bend portion (1421) and the second step portion (1320), between the fourth bend portion (1425) and the second step portion (1320), and between the 2-2 body portion (1422) and the second step portion (1320) to fix the second bracket (1420).

[0159] That is, the second bracket (1420) may be positioned on the second step portion (1320), the third bend portion (1421) and the fourth bend portion (1425) may be spaced apart with the second step portion (1320) in between, and the body portion (1530) and the second-second body portion (1422) may be positioned with the second step portion (1320) in between.

[0160] At this time, a pair of first-second extension portions (1520) may extend from both ends of the third direction of the body portion (1530), but may extend in a direction away from the body portion (1530), and may extend so that the distance between the ends of the pair of first-second extension portions (1520) becomes closer.

[0161] Here, the second bracket (1420) is positioned on the second step portion (1320), and the first-second extension portion (1520) is arranged to overlap the second bracket (1420) and the second step portion (1320) in the second direction, and the pair of first-second extension portions (1520) are extended so that the distance between the ends becomes closer to each other in the direction away from the body portion (1530), so that the second insertion portion (1423) can be easily inserted into the inside of the second convex portion (1521), and the second insertion portion (1423) can be inserted into the inside of the second convex portion (1521) and fix the body portion (1530). Additionally, the second insertion portion (1423) protrudes to have a convex hemispherical shape and comes into contact with the inner surface of the second convex portion (1521), and the mover (1200) can be tilted based on the second insertion portion (1423).

[0162] To explain this in more detail, as illustrated in FIG. 8, a second insertion portion (1423) is inserted into the inner side of the second convex portion (1521), and a part of the inner side of the second convex portion (1521) and the outer side of the second insertion portion (1423) come into contact with each other, and the mover (1200) tilts based on the second convex portion (1521) and the second insertion portion (1423), which can guide the mover (1200) to tilt in the second direction based on the third direction.

[0163] Additionally, the third bend portion (1421) and the fourth bend portion (1425) of the second bracket (1420) may be spaced apart from the body portion (1530) in the first direction by a second gap at a predetermined interval. The angle at which the mover (1200) tilts may be limited depending on the gap between the third bend portion (1421) and the fourth bend portion (1425) of the second bracket (1420) and the body portion (1530).

[0164] For example, if the third bend portion (1421) and the fourth bend portion (1425) of the second bracket (1420) and the body portion (1530) are in contact with each other, if the mover (1200) tilts, the body portion (1530) is caught on the ends of the third bend portion (1421) and the fourth bend portion (1425), and since the mover (1200) cannot be tilted by the third bend portion (1421) and the fourth bend portion (1425), it may be desirable for the ends of the third bend portion (1421) and the fourth bend portion and the body portion (1530) to be spaced apart from each other.

[0165] As described above, the first camera actuator (1000) according to the embodiment of the present invention can guide the mover (1200) to tilt based on the first convex portion (1511) and the first insertion portion (1413), and guide the mover (1200) to tilt based on the second convex portion (1521) and the second insertion portion (1423).

[0166] In addition, the tilt axis formed by the first convex portion (1511) and the first insert portion (1413) and the tilt axis formed by the second convex portion (1521) and the second insert portion (1423) are spaced apart from each other in the first direction and are connected through the body portion (1530), so that the mover (1200) can be effectively prevented from rolling in a direction other than the determined tilt axis.

[0167] Meanwhile, referring to FIGS. 9 to 12 to explain a first camera actuator (1000) according to a modified example of the present invention, as illustrated in FIG. 9, the first step portion (1220) further includes a first recessed portion (1221) that is recessed in the second direction, a first ball member (1B1) is disposed in the first recessed portion (1221), and a first-first hole (1414) in which the first ball member (1B1) is disposed may be formed in the first bent portion (1411) and the second bent portion (1415) of the first bracket (1410).

[0168] That is, the first camera actuator (1000) according to the modified example of the present invention is formed with a first recessed portion (1221), a first ball member (1B1), and a 1-1 hole (1414) instead of the first insertion portion (1413). The first recessed portion (1221) is a pair of spaces that are recessed in the second direction in the first step portion (1220), and may be formed in each of the pair of first step portions (1220). In addition, the first ball member (1B1) is arranged in the pair of first recessed portions (1221) and the 1-1 hole (1414), and the first bracket (1410) may be fixed to the first step portion (1220) so that the first ball member (1B1) is inserted into the 1-1 hole (1414). At this time, the first ball member (1B1) may be a ball member used in a bearing, but may not necessarily be limited thereto.

[0169] At this time, since it is generally somewhat difficult to form the first insertion portion (1413) to have a perfect hemispherical shape, by using the first ball member (1B1) instead of the first insertion portion (1413), the problem of increased power consumption due to increased friction between the inner surface of the first convex portion (1511) and the outer surface of the first insertion portion (1413) can be solved.

[0170] That is, by utilizing the first ball member (1B1), the frictional force problem as described above can be more easily solved, and since the first ball member (1B1) is effectively fixed by the first-1 hole (1414) of the first bracket (1410), tilting of the mover (1200) through the first frame (1500) can be made easier.

[0171] More specifically, as illustrated in FIG. 10, a pair of first ball members (1B1) are arranged to overlap each other in the second direction, and the body of the mover (1200), the first ball member (1B1), the first-first hole (1414), the first recessed portion (1221), and the first convex portion (1511) in the recessed space (1230) can be arranged to overlap each other. That is, when the first ball member (1B1) is provided and the mover (1200) tilts in the third direction with respect to the second direction, it can tilt with respect to the first ball member (1B1).

[0172] Meanwhile, as illustrated in FIG. 11, the second step portion (1320) may have a second recessed portion (1321) formed therein that is recessed in the third direction, a second ball member (1B2) may be arranged in the second recessed portion (1321), and a first-second hole (1424) may be formed in the third bent portion (1421) and the fourth bent portion (1425) of the second bracket (1420).

[0173] Here, since the second recessed portion (1321) is formed by recessing in the third direction in the second step portion (1320), it may be formed in an area of ​​the second step portion (1320) that is recessed in the third direction as described above. That is, the second recessed portion (1321) may not be formed in an area of ​​the second step portion (1320) that is recessed in the first direction.

[0174] That is, the first camera actuator (1000) according to the modified example of the present invention is formed with a second recessed portion (1321), a second ball member (1B2), and a first-second hole (1424) instead of the second insertion portion (1423). The second recessed portions (1321) may be formed to be recessed in a third direction, and a pair may be formed to be spaced apart in the third direction. In addition, the second ball member (1B2) may be arranged in a pair of the second recessed portions (1321) and the first-second hole (1424), and the second bracket (1420) may be fixed to the second step portion (1320) so that the second ball member (1B2) is inserted into the first-second hole (1424). At this time, the second ball member (1B2) may be a ball member used in a bearing, but may not necessarily be limited thereto.

[0175] At this time, since it is generally somewhat difficult to form the second insertion portion (1423) to have a perfect hemispherical shape, by using the second ball member (1B2) instead of the second insertion portion (1423), the frictional force between the inner surface of the second convex portion (1521) and the outer surface of the second insertion portion (1423) increases, thereby solving the problem of increased power consumption.

[0176] That is, by utilizing the second ball member (1B2), the frictional force problem as described above can be more easily solved, and since the second ball member (1B2) is effectively fixed by the first-second hole (1424) of the second bracket (1420), tilting of the mover (1200) through the first frame (1500) can be made easier.

[0177] More specifically, as illustrated in FIG. 12, a pair of second ball members (1B2) are arranged to overlap each other in the third direction, and the wall member (1310), the second ball member (1B2), the first-second hole (1424), the second recessed portion (1321), and the second convex portion (1521) in the second step portion (1320) can be arranged to overlap each other. That is, when the second ball member (1B2) is provided and the mover (1200) tilts in the second direction with respect to the third direction, it can tilt with respect to the second ball member (1B2).

[0178] The first camera actuator (1000) according to the above-described embodiment and modified example of the present invention guides a mover (1200) that tilts based on different axes, effectively reduces power consumption of the guided mover (1200), and has an advantage of having a stable structure because it is effectively fixed due to the inclined structure of a pair of first-first extension parts (1510) and a pair of first-second extension parts (1520).

[0179] In addition, the mover (1200) is formed by a tilt axis formed by a first bracket (1410) and a second bracket (1420) and a first frame (1500), and the hinge portions (1410, 1420, 1500) are positioned between the mover (1200) and the support portion (1300), i.e., on the inside of the first housing (1100), so that stable operation can be achieved.

[0180] First, as illustrated in FIG. 13, a second camera actuator (A2) according to an embodiment of the present invention includes a second housing (2100), a fixed lens assembly (2200) disposed in the second housing (2100), at least one movable lens assembly (2300) that moves in a first direction within the second housing (2100), a panel portion (2410, 2440) disposed on one side of the movable lens assembly (2300), and a first shaft (2510, 2530) and a second shaft (2520, 2540) disposed between the movable lens assembly (2300) and the panel portion (2410, 2440).

[0181] The second housing (2100) may form the exterior of the second camera actuator (A2) according to an embodiment of the present invention. In addition, openings penetrating in the third direction are formed on both sides of the second housing (2100) in the third direction, and the second-first coil (2620) and the second-second coil (2640), which will be described later, may be arranged in the above-described openings. In addition, the second housing (2100) may have another opening formed that opens in the first direction, and the opening may be formed on one side in the direction toward the first camera actuator (A1) based on FIG. 13, but the opening may not be formed in the direction opposite to the direction toward the first camera actuator (A1) based on FIG. 13.

[0182] The fixed lens assembly (2200) may be positioned on one side of the second housing (2100) in the first direction. This allows the opening of the second housing (2100) to be closed in the first direction. In addition, the fixed lens assembly (2200) may be fixed or coupled to the second housing (2100) by being coupled with the first panel portion (2410) and the second panel portion (2440), as will be described in more detail with reference to the drawings to be described later.

[0183] At least one movable lens assembly (2300) may be positioned so as to move along a first direction parallel to the optical axis inside the second housing (2100). In the second camera actuator (A2) according to the embodiment of the present invention, the movable lens assembly (2300) is illustrated as a pair positioned at the upper and lower sides in the first direction, but a plurality may be provided depending on the design, and the present invention may not necessarily be limited to what has been mentioned.

[0184] Here, in the detailed description of the present invention, in order to facilitate a smooth understanding of the present invention, the fixed lens assembly (2200) and the adjacent movable lens assembly (2300) in the first direction are described as the first lens assembly (2310), and the second lens assembly (2350) is arranged relatively far from the fixed lens assembly (2200) in the first direction, and it may be interpreted without being limited to the first and second mentioned.

[0185] The first lens assembly (2310) and the second lens assembly (2350) each include a lens group, a barrel portion, and an extension portion formed on one side of the barrel portion, and the extension portion of the first lens assembly (2310) and the extension portion of the second lens assembly (2350) can be arranged to face different directions in the third direction.

[0186] In addition, the first shaft (2510, 2530) and the second shaft (2520, 2540) are arranged to be spaced apart from each other in the second direction and can be in contact with the extensions of the first lens assembly (2310) and the second lens assembly (2350) described above, which will be described in more detail with reference to the drawings to be described later.

[0187] In addition, in order to facilitate easier understanding by distinguishing the description of the first lens assembly (2310) and the second lens assembly (2350) and the first shaft (2510, 2530) and the second shaft (2520, 2540), the description is divided into the first lens assembly (2310), the first lens group (2321), the first barrel portion (2322), the second-first extension portion (2323), the second lens assembly (2350), the second lens group (2351), the second barrel portion (2352), the second-second extension portion (2353), the first-first shaft (2510), the second-first shaft (2520), the first-second shaft (2530), and the second-second shaft (2540), and this will be distinguished and described in more detail through the drawings described later.

[0188] At this time, a first shaft (2510, 2530) and a second shaft (2520, 2540) are arranged on each of the first lens assembly (2310) and the second lens assembly (2350), and the first shaft (2510, 2530) arranged on the first lens assembly (2310) may be a 1-1 shaft (2510), and the second shaft (2520, 2540) arranged on the first lens assembly (2310) may be a 2-1 shaft (2520). In addition, the first shaft (2510, 2530) arranged on the second lens assembly (2350) may be a 1-2 shaft (2530), and the second shaft (2520, 2540) arranged on the second lens assembly (2350) may be a 2-2 shaft (2540).

[0189] Also, to avoid confusion in the explanation to be given later, let's first explain some of the configurations. The first region (2324, 2354) may include a first-first region (2324) formed in the second-first extension (2323) and a first-second region (2354) formed in the second-second extension (2353), and the second region (2325, 2355) may include a second-first region (2325) formed in the second-first extension (2323) and a second-second region (2355) formed in the second-second extension (2353). In addition, the third region (2411, 2441) may include a third-first region (2411) formed in the first panel portion (2410) and a third-second region (2441) formed in the second panel portion (2440). Additionally, the fourth region (2412, 2442) may include a fourth-first region (2412) formed in the first panel portion (2410) and a fourth-second region (2442) formed in the second panel portion (2440).

The second groove (2327, 2357) may include a second-first groove (2327) in contact with the second-first shaft (2520) and a second-second groove (2357) in contact with the second-second shaft. The third groove (2413, 2443) may include a third-first groove (2413) formed in the first panel portion (2410) and a third-second groove (2443) formed in the second panel portion (2440). The fourth groove (2414, 2444) may include a 4-1 groove (2414) formed in the first panel portion (2410) and a 4-2 groove (2444) formed in the second panel portion (2440).

[0191] The second holes (2121, 2122) may include a 2-1 hole (2121) arranged adjacent to the first panel portion (2410) within the second housing (2100) and a 2-2 hole (2122) arranged adjacent to the second panel portion (2440) within the second housing (2100). The third holes (2416, 2446) may include a 3-1 hole (2416) formed in the first panel portion (2410) and a 3-2 hole (2446) formed in the second panel portion (2440).

[0192] The second protrusions (2111, 2112) may include a second-first protrusion (2111) inserted into the third-first hole (2416) of the first panel portion (2410) and a second-second protrusion (2112) inserted into the third-second hole (2446) of the second panel portion (2440). The third protrusions (2415, 2445) may include a third-first protrusion (2415) formed in the first panel portion (2410) and a third-second protrusion (2445) formed in the second panel portion (2440).

[0193] The first auxiliary magnet (2341, 2371) may include a first auxiliary magnet (2341) disposed on the second-first extension (2323) and a first auxiliary magnet (2371) disposed on the second-second extension (2353). The second auxiliary magnet (2342, 2372) may include a second-first auxiliary magnet (2342) disposed on the second-first extension (2323) and a second-second auxiliary magnet (2372) disposed on the second-second extension (2353).

[0194] Meanwhile, a second-first magnet (2330) may be placed on a second-first extension (2323) in the third direction based on the first lens assembly (2310), and a first panel portion (2410) may be placed facing the second-first extension (2323). Here, the first panel portion (2410) may be placed adjacent to the third-direction inner wall on the inside of the second housing (2100), and may be in contact with the first shaft (2510, 2530) and the second shaft (2520, 2540).

[0195] In addition, the 2-1 magnet (2330) and the 2-1 coil (2620) are arranged to face each other, the 2-1 coil (2620) is arranged in the third direction opening of the above-described second housing (2100), the first yoke (2610) is arranged on the outside of the 2-1 coil (2620), and the first yoke (2610) may be arranged on the outside of the second housing (2100). That is, the 2-1 coil (2620) is arranged in the third direction opening of the second housing (2100), so it is arranged across the inside and outside of the second housing (2100), and in the case of the first yoke (2610), it may be arranged to face the outer surface of the second housing (2100) in the third direction.

[0196] In addition, the first yoke (2610) may be formed of a magnetic material having a predetermined magnetic force, or may be formed of a non-magnetic material that does not exhibit magnetism. Even when formed of a non-magnetic material, it may be preferable to form the first yoke (2610) of a material on which the attractive force of the second-first magnet (2330) acts, but it may not necessarily be limited to what has been mentioned.

[0197] Meanwhile, a second-second magnet (2360) may be placed on a second-second extension portion (2353) in the third direction based on the second lens assembly (2350), and a second panel portion (2440) may be placed facing the second-second extension portion (2353). Here, the second panel portion (2440) may be placed adjacent to the third-direction inner wall on the inside of the second housing (2100) and may be in contact with the first shaft (2510, 2530) and the second shaft (2520, 2540).

[0198] In addition, the 2-2 magnet (2360) and the 2-2 coil (2640) are arranged to face each other, the 2-2 coil (2640) is arranged in the third direction-oriented opening of the above-described 2nd housing (2100), the 2nd yoke (2630) is arranged on the outside of the 2-2 coil (2640), and the 2nd yoke (2630) may be arranged on the outside of the 2nd housing (2100). That is, the 2-2 coil (2640) is arranged in the third direction-oriented opening of the 2nd housing (2100), so it is arranged across the inside and outside of the 2nd housing (2100), and in the case of the 2nd yoke (2630), it may be arranged to face the outer surface of the 2nd housing (2100) in the third direction.

[0199] In addition, the second yoke (2630) may be formed of a magnetic material having a predetermined magnetic force, or may be formed of a non-magnetic material that does not exhibit magnetism. Even when formed of a non-magnetic material, it may be preferable to form it of a material on which the attractive force of the second-second magnet (2360) acts, but it may not necessarily be limited to what has been mentioned.

[0200] Referring to FIG. 14 to explain a more detailed configuration based on the above description, as illustrated in FIG. 14, the first lens assembly (2310) may include a first lens group (2321), a first barrel portion (2322), and a second-first extension portion (2323) formed on one side of the first barrel portion (2322), more specifically, on one side in the third direction, as described above.

[0201] Here, the 2-1 extension (2323) is formed with a first mounting space (2328) in which the 2-1 magnet (2330) is placed, and a first partition wall (2329) may be placed at both ends of the first mounting space (2328) in the first direction to prevent the 2-1 magnet (2330) from being detached during the movement of the first lens assembly (2310).

[0202] In addition, as described above, the 1-1 shaft (2510) and the 2-1 shaft (2520) are arranged to be spaced apart in the second direction, and the 2-1 extension (2323) can be divided into a 1-1 region (2324) spaced apart from the 1-1 shaft (2510) and the 2-1 shaft (2520) in the third direction and a 2-1 region (2325) that is in contact with the 1-1 shaft (2510) and the 2-1 shaft (2520). Here, the 1-1 region (2324) and the 2-1 region (2325) can be formed to be stepped.

[0203] At this time, the 2-1 region (2325) can be divided into a 1-1 groove (2326) that comes into contact with the 1-1 shaft (2510) and a 2-1 groove (2327) that comes into contact with the 2-1 shaft (2520). In addition, the 1-1 groove (2326) and the 2-1 groove (2327) may have different cross-sectional shapes when cut in the second direction. That is, the part where the 1-1 groove (2326) comes into contact with the 1-1 shaft (2510) and the part where the 2-1 groove (2327) comes into contact with the 2-1 shaft (2520) may be different from each other. Alternatively, there may be a difference in the number of surfaces where the 1-1 groove (2326) and the 1-1 shaft (2510) come into contact with each other and the number of surfaces where the 2-1 groove (2327) and the 2-1 shaft (2520) come into contact with each other.

[0204] Meanwhile, referring to FIG. 15 to explain the first panel portion (2410) in more detail, as illustrated in FIG. 15, the first panel portion (2410) may include a 3-1 region (2411) spaced apart from the 1-1 shaft (2510) and the 2-1 shaft (2520) in the third direction and a 4-1 region (2412) in contact with the 1-1 shaft (2510) and the 2-1 shaft (2520). Here, the 4-1 region (2412) may include a 3-1 groove (2413) formed to be open in the first direction and a 4-1 groove (2414) having one side closed in the first direction. Specifically, the 3-1 groove (2413) is formed so that the 1-1 shaft (2510) and the 2-1 shaft (2520) pass through it in the first direction, and the upper and lower sides are open, and the 4-1 groove (2414) is formed so that the direction facing the 3-1 groove (2413) in the first direction is open, but a first step portion (2414a) extending in the third direction from the inside of the 4-1 groove (2414) is formed in the direction facing the opposite direction to the 3-1 groove (2413), so that it can come into contact with the ends of the 1-1 shaft (2510) and the 2-1 shaft (2520) in the first direction. That is, the 3-1 groove (2413) supports the 1-1 shaft (2510) and the 2-1 shaft (2520) in the 3rd direction, and the 4-1 groove (2414) supports the 1-1 shaft (2510) and the 2-1 shaft (2520) in the 3rd direction, while also supporting the 1-1 shaft (2510) and the 2-1 shaft (2520) in the 1st direction.

[0205] In addition, due to the attractive force between the 2-1 magnet (2330) arranged in the first settling space (2328) of the 2-1 extension (2323) and the first yoke (2610) arranged to face the 2-1 magnet (2330), the 2-1 extension (2323) is brought into close contact in the third direction, and as it is brought into close contact, the 1-1 shaft (2510) and the 2-1 shaft (2520) can be supported by the 1-1 groove (2326), the 2-1 groove (2327), the 3-1 groove (2413), and the 4-1 groove (2414).

[0206] Meanwhile, the first panel portion (2410) includes a first connecting portion (2420) in which the 3-1 region (2411) and the 4-1 region (2412) are formed to be stepped from each other, a pair of 3-1 grooves (2413) are connected in the second direction, and a 4-1 groove (2414) is connected in the second direction, and further includes a second frame (2430) that extends in the third direction in the opposite direction to the direction toward the 2-1 extension portion (2323) from an end adjacent to the 3-1 groove (2413), and at least one 3-1 hole (2416) penetrating in the first direction can be formed in the second frame (2430). Additionally, a 3-1 protrusion (2415) may be formed at the lower portion of the first step (2414a) of the 4-1 groove (2414) to be fixed to the second housing (2100). At this time, the 3-1 hole (2416) and the 3-1 protrusion (2415) will be described in more detail with reference to the drawings to be described later.

[0207] Meanwhile, referring to FIG. 16 to explain the arrangement relationship of the 1-1 shaft (2510) and the 2-1 shaft (2520), as illustrated in FIG. 16, a 2-1 extension (2323) is formed on one side of the 1st barrel portion (2322), that is, on one side in the direction toward the 2-1 coil (2620), and the 2-1 magnet (2330), the 2-1 coil (2620), and the 1st yoke (2610) arranged in the 2-1 extension (2323) are arranged so that at least a portion overlaps each other in the third direction, and the 1-1 shaft (2510) and the 2-1 shaft (2520) can be supported by the attractive force between the 2-1 magnet (2330) and the 1st yoke (2610).

[0208] At this time, the 1-1 shaft (2510) and the 2-1 shaft (2520) are arranged to be spaced apart from each other in the second direction, and the 1-1 shaft (2510) may be arranged to be spaced apart from the 1-1 region (2324) and the 3-1 region (2411) in the third direction, and to be in contact with the 1-1 groove (2326), the 3-1 groove (2413), and the 4-1 groove (2414). Here, when the 1-1 shaft (2510) is arranged as a magnetic body, the 1-1 shaft (2510) may be supported by the attractive force between the 1-1 shaft (2510) and the 1st yoke (2610) in addition to the attractive force between the 2-1 magnet (2330) and the 1st yoke (2610). However, this is just one example and may not necessarily be limited to what has been mentioned.

[0209] In addition, the first-1 groove (2326) forms a first contact surface (2326a) that comes into contact with the first-1 shaft (2510) in the third direction, and can prevent the problem of the support force becoming weak due to a relatively small contact area.

[0210] In addition, the 2-1 coil (2620) may be arranged to have multiple layers in the third direction or multiple layers in the first direction, which may form a relatively high electromagnetic force to further improve the driving force of the first lens assembly (2310), and accordingly, the 2-1 coil (2620) may be formed with two inputs to which voltage is applied and two outputs through which voltage is discharged via the 2-1 coil (2620). However, this is only one example, and may not necessarily be limited to what has been mentioned.

[0211] In addition, in the case of the 2-1 shaft (2520), it may be arranged to be spaced apart in the third direction from the 1-1 region (2324) and the 3-1 region (2411), and to be in contact with the 2-1 groove (2327), the 3-1 groove (2413), and the 4-1 groove (2414). Here, when the 2-1 shaft (2520) is arranged as a magnetic body, the 2-1 shaft (2520) may be supported by the attractive force between the 2-1 shaft (2520) and the first yoke (2610), in addition to the attractive force between the 2-1 magnet (2330) and the first yoke (2610). However, this is just one example and may not necessarily be limited to what has been mentioned.

[0212] As described above, the shapes of the first-first groove (2326) and the second-first groove (2327) are different, and the area where the first-first groove (2326) comes into contact with the first-first shaft (2510) and the area where the second-first groove (2327) comes into contact with the second-first shaft (2520) are different, which can effectively reduce the frictional force between the first-first shaft (2510) and the second-first shaft (2520) during the driving process of the first lens assembly (2310), thereby improving efficiency.

[0213] Additionally, the 1-1 shaft (2510) and the 2-1 shaft (2520) may be fixed to the 3-1 groove (2413) and the 4-1 groove (2414) through separate adhesive members, and may not necessarily be limited to the examples.

[0214] In addition, the first connecting portion (2420) may be in contact with the inner surface of the second housing (2100) in the third direction, and when the first connecting portion (2420) is in contact with the inner surface of the second housing (2100) in the third direction, the contact may be made when the attractive force between the 2-1 magnet (2330) and the first yoke (2610), the attractive force between the 1-1 shaft (2510) and the first yoke (2610), and the attractive force between the 2-1 shaft (2520) and the first yoke (2610) vary depending on the applied voltage or increase due to an unspecified factor, when the shaking of the first panel portion (2410) is prevented, and the contact may also be made by an external impact, and this may have the effect of relatively lowering the pressure and frictional force applied to the first lens assembly (2310), but it should not be interpreted as being limited to what has been mentioned.

[0215] Meanwhile, referring to FIG. 17, the first panel portion (2410) can be coupled to one side of the second housing (2100) in the third direction. Here, as described above, the 3-1 hole (2416) is formed in the second frame (2430) of the first panel portion (2410), the 3-1 protrusion (2415) is formed at the end of the 4-1 groove (2414) in the first direction, and the second housing (2100) can be formed with the 2-1 protrusion (2111) penetrating the 3-1 hole (2416) and the 2-1 hole (2121) into which the 3-1 protrusion (2415) is inserted. Additionally, as illustrated in FIG. 17, the 1-1 shaft (2510) or the 2-1 shaft (2520) may be spaced apart from the 1-1 region (2324) and the 3-1 region (2411) in a third direction.

[0216] That is, the 1-1 shaft (2510) is formed with a space spaced apart in the third direction by the 3-1 region (2411), and the spaced apart between the 1-1 shaft (2510) and the 3-1 region (2411) is fixed because the 1-1 shaft (2510) and the 3-1 region (2411) do not move, and since the first lens assembly (2310) moves in the first direction, the spaced apart between the 1-1 shaft (2510) and the 1-1 region (2324) can be continuously variable according to the movement of the first lens assembly (2310). In addition, the spaced apart between the 1-1 shaft (2510) and the 1-1 region (2324) and the spaced apart between the 1-1 shaft (2510) and the 3-1 region (2411) can overlap each other at least partially in the third direction.

[0217] To put it differently, only the first direction end portions of the 2-1 extension portion (2323) and the first direction end portions of the 1st panel portion (2410) can be in contact with the 1-1 shaft (2510). At this time, in describing FIG. 17, the 1-1 shaft (2510) and the 2-1 shaft (2520) were used interchangeably, but this means that there is no problem in interpreting by applying the 1-1 shaft (2510) or the 2-1 shaft (2520), and the interchangeability of the 1-1 shaft (2510) and the 2-1 shaft (2520) can be understood in more detail through the other drawings described above.

[0218] In addition, since the 3-1 region (2411) and the 1-1 region (2324) are spaced apart from the 1-1 shaft (2510) and the 2-1 shaft (2520) in the third direction, more stable operation can be achieved even if the 2-1 extension (2323) is bent due to heat, external impact, etc., or the 1-1 shaft (2510) or the 2-1 shaft (2520) is bent.

[0219] Meanwhile, referring to FIGS. 18 and 19 to explain a second camera actuator (A2) according to a modified example of the present invention, first, as shown in FIG. 18, the 1-1 groove (2326) is arranged between the 1-1 regions (2324) in the first direction, and the 2-1 groove (2327) can be arranged at both ends of the 1-1 regions (2324) in the first direction.

[0220] This is different from the case where the first-first groove (2326) and the second-first groove (2327) are arranged at both ends of the first-direction region (2324) of the first-first groove (2326) in the second camera actuator (A2) according to the previous embodiment of the present invention, in which the first-first region (2324) is arranged at both ends of the first-direction region of the first-first groove (2326), so that the frictional force can be further minimized.

[0221] At this time, the 1-1 groove (2326) has a first contact surface (2326a) formed as described above, and thus has more contact points or contact surfaces or contact areas with the 1-1 shaft (2510) than the 2-1 groove (2327), so that it is possible to secure relatively high stability while also securing low friction, thereby pursuing higher efficiency.

[0222] Meanwhile, according to another embodiment of the present invention, a second camera actuator (A2) may have auxiliary magnets (2341, 2342) arranged on the other side opposite to the direction in which the 2-1 magnet (2330) is arranged with respect to the 1-1 region (2324), as illustrated in FIG. 19.

[0223] Here, the auxiliary magnets (2341, 2342) may include a 1-1 auxiliary magnet (2341) that overlaps at least a portion of the 1-1 shaft (2510) in the third direction and a 2-1 auxiliary magnet (2342) that overlaps at least a portion of the 2-1 shaft (2520) in the third direction, and in FIG. 19, they are shown as being attached to the rear surface in the third direction of the 2-1 extension portion (2323), that is, the surface opposite to the front surface where the 2-1 magnet (2330) is arranged, but a separate space may be formed on the rear surface in the third direction of the 2-1 extension portion (2323) described above so that the 1-1 auxiliary magnet (2341) and the 2-1 auxiliary magnet (2342) may be arranged.

[0224] In this way, when the first-first auxiliary magnet (2341) and the second-first auxiliary magnet (2342) are arranged, the first-first shaft (2510) and the second-first shaft (2520) may be magnetic substances, and when the first-first shaft (2510) and the second-first shaft (2520) are magnetic substances, the first-first groove (2326) and the second-first groove (2327) can more effectively come into contact with the first-first shaft (2510) and the second-first shaft (2520) by the attractive force between the first-first auxiliary magnet (2341) and the first-first shaft (2510) and the attractive force between the second-first auxiliary magnet (2342) and the second-first shaft (2520). This can prevent shaking that occurs during the driving process of the first lens assembly (2310).

[0225] If the first-first shaft (2510) and the second-first shaft (2520) are non-magnetic, the first-first groove (2326) and the second-first groove (2327) can be effectively pressed against the first-first shaft (2510) and the second-first shaft (2520) by the attractive force between the first-first auxiliary magnet (2341) and the first yoke (2610) and the attractive force between the second-first auxiliary magnet (2342) and the first yoke (2610). In addition, it can be implemented by combining the modified example of FIG. 18 described above with another embodiment of FIG. 19, and various embodiments can be anticipated according to the design intention of those skilled in the art.

[0226] Meanwhile, as illustrated in FIG. 20, the second lens assembly (2350) may include a second lens group (2351), a second barrel portion (2352), and a second-second extension portion (2353) formed on one side of the second barrel portion (2352), more specifically, on one side in the third direction, as described above.

[0227] Here, the second-2 extension (2353) is formed with a second mounting space (2358) in which a second-2 magnet (2360) is placed, and a second partition wall (2359) may be placed at both ends of the second mounting space (2358) in the first direction to prevent the second-2 magnet (2360) from being detached during the movement of the first lens assembly (2310).

[0228] In addition, as described above, the first-second shaft (2530) and the second-second shaft (2540) are arranged to be spaced apart in the second direction, and the second-second extension (2353) can be divided into a first-second region (2354) spaced apart from the first-second shaft (2530) and the second-second shaft (2540) in the third direction and a second-second region (2355) in contact with the first-second shaft (2530) and the second-second shaft (2540). Here, the first-second region (2354) and the second-second region (2355) can be formed to be stepped.

[0229] At this time, the 2-2 region (2355) can be divided into a 1-2 groove (2356) that comes into contact with the 1-2 shaft (2530) and a 2-2 groove (2357) that comes into contact with the 2-2 shaft (2540). In addition, the 1-2 groove (2356) and the 2-2 groove (2357) may have different cross-sectional shapes when cut in the second direction. That is, the part where the 1-2 groove (2356) comes into contact with the 1-2 shaft (2530) and the part where the 2-2 groove (2357) comes into contact with the 2-2 shaft (2540) may be different from each other. Alternatively, there may be a difference in the number of surfaces where the 1st-2nd groove (2356) and the 1st-2nd shaft (2530) come into contact with each other and the number of surfaces where the 2nd-2nd groove (2357) and the 2nd-2nd shaft (2540) come into contact with each other.

[0230] Meanwhile, referring to FIG. 21 to explain the second panel portion (2440) in more detail, as illustrated in FIG. 21, the second panel portion (2440) may include a 3-2 region (2441) spaced apart from the 1-2 shaft (2530) and the 2-2 shaft (2540) in the third direction and a 4-2 region (2442) in contact with the 1-2 shaft (2530) and the 2-2 shaft (2540). Here, the 4-2 region (2442) may include a 3-2 groove (2443) formed to be open in the first direction and a 4-2 groove (2444) having one side closed in the first direction. Specifically, the 3-2 groove (2443) is formed so that the 1-2 shaft (2530) and the 2-2 shaft (2540) pass through it in the first direction, and the 4-2 groove (2444) is formed so that the direction facing the 3-2 groove (2443) in the first direction is open, but a second step portion (2444a) extending in the third direction from the inside of the 4-2 groove (2444) is formed in the direction facing the opposite direction to the 3-2 groove (2443), so that it can come into contact with the ends of the 1-2 shaft (2530) and the 2-2 shaft (2540) in the first direction. That is, the 3rd-2nd groove (2443) supports the 1st-2nd shaft (2530) and the 2nd-2nd shaft (2540) in the 3rd direction, and the 4th-2nd groove (2444) supports the 1st-2nd shaft (2530) and the 2nd-2nd shaft (2540) in the 3rd direction, while also supporting the 1st-2nd shaft (2530) and the 2nd-2nd shaft (2540) in the 1st direction.

[0231] In addition, due to the attractive force between the second-2 magnet (2360) arranged in the second settling space (2358) of the second-2 extension (2353) and the second yoke (2630) arranged to face the second-2 magnet (2360), the second-2 extension (2353) is brought into close contact in the third direction, and as it is brought into close contact, the first-2 shaft (2530) and the second-2 shaft (2540) can be supported by the first-2 groove (2356), the second-2 groove (2357), the third-2 groove (2443), and the fourth-2 groove (2444).

[0232] Meanwhile, the second panel portion (2440) includes a second connecting portion (2450) in which the 3-2 region (2441) and the 4-2 region (2442) are formed to be stepped from each other, a pair of 3-2 grooves (2443) are connected in the second direction, and a 4-2 groove (2444) is connected in the second direction, and further includes a third frame (2460) that extends in the third direction in the opposite direction to the direction toward the 2-2 extension portion (2353) from an end adjacent to the 3-2 groove (2443), and at least one 3-2 hole (2446) penetrating in the first direction can be formed in the third frame (2460). Additionally, a 3-2 protrusion (2445) may be formed at the lower portion of the second step (2444a) of the 4-2 groove (2444) to be fixed to the second housing (2100). At this time, the 3-2 hole (2446) and the 3-2 protrusion (2445) will be described in more detail with reference to the drawings to be described later.

[0233] Meanwhile, referring to FIG. 22 to explain the arrangement relationship of the 1st-2 shaft (2530) and the 2nd-2 shaft (2540), as illustrated in FIG. 22, a 2nd-2 extension (2353) is formed on one side of the 2nd barrel portion (2352), that is, on one side in the direction toward the 2nd-2 coil (2640), and the 2nd-2 magnet (2360), the 2nd-2 coil (2640), and the 2nd yoke (2630) arranged in the 2nd-2 extension (2353) are arranged so that at least a portion overlaps each other in the third direction, and the 1st-2 shaft (2530) and the 2nd-2 shaft (2540) can be supported by the attractive force between the 2nd-2 magnet (2360) and the 2nd yoke (2630).

[0234] At this time, the first-second shaft (2530) and the second-second shaft (2540) are arranged to be spaced apart from each other in the second direction, and the first-second shaft (2530) may be arranged to be spaced apart from the first-second region (2354) and the third-second region (2441) in the third direction, and to be in contact with the first-second groove (2356), the third-second groove (2443), and the fourth-second groove (2444). Here, when the first-second shaft (2530) is arranged as a magnetic body, the first-second shaft (2530) may be supported by the attractive force between the first-second shaft (2530) and the second yoke (2630) in addition to the attractive force between the second-second magnet (2360) and the second yoke (2630). However, this is just one example and may not necessarily be limited to what has been mentioned.

[0235] In addition, the 1-2 groove (2356) forms a second contact surface (2356a) that comes into contact with the 1-2 shaft (2530) in the third direction, and can prevent the problem of the support force becoming weak due to a relatively small contact area.

[0236] In addition, the 2-2 coil (2640) may be arranged to have multiple layers in the third direction or multiple layers in the first direction, which may form a relatively high electromagnetic force to further improve the driving force of the first lens assembly (2310), and accordingly, the 2-2 coil (2640) may be formed with two inputs to which voltage is applied and two outputs through which voltage is discharged via the 2-2 coil (2640). However, this is only one example, and may not necessarily be limited to what has been mentioned.

[0237] In addition, in the case of the 2-2 shaft (2540), it may be arranged to be spaced apart from the 1-2 region (2354) and the 3-2 region (2441) in the third direction, and to be in contact with the 2-2 groove (2357), the 3-2 groove (2443), and the 4-2 groove (2444). Here, when the 2-2 shaft (2540) is arranged as a magnetic body, the 2-2 shaft (2540) may be supported by the attractive force between the 2-2 shaft (2540) and the 2nd yoke (2630), in addition to the attractive force between the 2-2 magnet (2360) and the 2nd yoke (2630). However, this is just one example and may not necessarily be limited to what has been mentioned.

[0238] As described above, the shapes of the first-second groove (2356) and the second-second groove (2357) are different, and the area where the first-second groove (2356) comes into contact with the first-second shaft (2530) and the area where the second-second groove (2357) comes into contact with the second-second shaft (2540) are different, which can effectively reduce the frictional force between the first-second shaft (2530) and the second-second shaft (2540) during the driving process of the first lens assembly (2310), thereby improving efficiency.

[0239] Additionally, the 1st-2 shaft (2530) and the 2nd-2 shaft (2540) may be fixed to the 3rd-2 groove (2443) and the 4th-2 groove (2444) through separate adhesive members, and may not necessarily be limited to the examples.

[0240] In addition, the second connecting portion (2450) may be in contact with the inner surface of the second housing (2100) in the third direction, and when the second connecting portion (2450) is in contact with the inner surface of the second housing (2100) in the third direction, the contact may be made when the attractive force between the second-2 magnet (2360) and the second yoke (2630), the attractive force between the first-2 shaft (2530) and the second yoke (2630), and the attractive force between the second-2 shaft (2540) and the second yoke (2630) vary depending on the applied voltage or increase due to an unspecified factor, when the shaking of the second panel portion (2440) is prevented, and the contact may also be made by an external impact, and this may have the effect of relatively lowering the pressure and frictional force applied to the first lens assembly (2310), but it should not be interpreted as being limited to what has been mentioned.

[0241] Meanwhile, referring to FIG. 23, the second panel portion (2440) can be coupled to one side of the second housing (2100) in the third direction. Here, as described above, a 3-2 hole (2446) is formed in the third frame (2460) of the second panel portion (2440), a 3-2 protrusion (2445) is formed at the end of the 4-2 groove (2444) in the first direction, and the second housing (2100) can be formed with a 2-2 protrusion (2112) penetrating the 3-2 hole (2446) and a 2-2 hole (2122) into which the 3-2 protrusion (2445) is inserted. Additionally, as illustrated in FIG. 23, the 1-2 shaft (2530) or the 2-2 shaft (2540) may be spaced apart from the 1-2 region (2354) and the 3-2 region (2441) in a third direction.

[0242] That is, the first-second shaft (2530) is formed with a space spaced apart in the third direction by the third-second region (2441), and the spaced apart between the first-second shaft (2530) and the third-second region (2441) is fixed because the first-second shaft (2530) and the third-second region (2441) do not move, and since the first lens assembly (2310) moves in the first direction, the spaced apart between the first-second shaft (2530) and the first-second region (2354) can be continuously varied according to the movement of the first lens assembly (2310). In addition, the spaced apart between the first-second shaft (2530) and the first-second region (2354) and the spaced apart between the first-second shaft (2530) and the third-second region (2441) can overlap each other at least partially in the third direction.

[0243] To put it differently, only the first direction end portions of the second-2 extension portion (2353) and the first direction end portions of the second panel portion (2440) can be in contact with the first-2 shaft (2530). At this time, in describing FIG. 23, the first-2 shaft (2530) and the second-2 shaft (2540) were used interchangeably, but this means that there is no problem in interpreting by applying the first-2 shaft (2530) or the second-2 shaft (2540), and the interchangeability of the first-2 shaft (2530) and the second-2 shaft (2540) can be understood in more detail through the other drawings described above.

[0244] In addition, since the 3-2 region (2441) and the 1-2 region (2354) are spaced apart from the 1-2 shaft (2530) and the 2-2 shaft (2540) in the third direction, more stable driving can be possible even if the 2-2 extension (2353) is bent due to heat, external impact, etc., or the 1-2 shaft (2530) or the 2-2 shaft (2540) is bent.

[0245] Meanwhile, referring to FIGS. 24 and 25 to explain a second camera actuator (A2) according to a modified example of the present invention, first, as shown in FIG. 24, the first-second groove (2356) is arranged between the first-second region (2354) in the first direction, and the second-second groove (2357) can be arranged at both ends of the first-second region (2354) in the first direction.

[0246] This is different from the case where the first-second groove (2356) and the second-second groove (2357) are arranged at both ends of the first-direction region (2354) in the second camera actuator (A2) according to the previous embodiment of the present invention, in which the first-second region (2354) is arranged at both ends of the first-direction region (2356), so that the frictional force can be further minimized.

[0247] At this time, the 1-2 groove (2356) has a second contact surface (2356a) formed as described above, and thus has more contact points or contact surfaces or contact areas with the 1-2 shaft (2530) than the 2-2 groove (2357), so that it is possible to secure relatively high stability while securing low friction and thus pursue higher efficiency.

[0248] Meanwhile, according to another embodiment of the present invention, the second camera actuator (A2) may have auxiliary magnets (2371, 2372) arranged on the other side opposite to the direction in which the second-2 magnet (2360) is arranged with respect to the first-2 area (2354), as illustrated in FIG. 25.

[0249] Here, the auxiliary magnets (2371, 2372) may include a first-second auxiliary magnet (2371) that overlaps at least a portion of the first-second shaft (2530) in the third direction, and a second-second auxiliary magnet (2372) that overlaps at least a portion of the second-second shaft (2540) in the third direction. In FIG. 25, it is illustrated as being attached to the third-direction rear surface of the second-second extension (2353), that is, the surface opposite to the front surface where the second-second magnet (2360) is arranged, but a separate space may be formed on the third-direction rear surface of the above-described second-second extension (2353) to arrange the first-second auxiliary magnet (2371) and the second-second auxiliary magnet (2372).

[0250] In this way, when the first-second auxiliary magnet (2371) and the second-second auxiliary magnet (2372) are arranged, the first-second shaft (2530) and the second-second shaft (2540) may be magnetic substances, and when the first-second shaft (2530) and the second-second shaft (2540) are magnetic substances, the first-second groove (2356) and the second-second groove (2357) can more effectively come into contact with the first-second shaft (2530) and the second-second shaft (2540) by the attractive force between the first-second auxiliary magnet (2371) and the first-second shaft (2530) and the attractive force between the second-second auxiliary magnet (2372) and the second-second shaft (2540). This can prevent shaking that occurs during the driving process of the first lens assembly (2310).

[0251] If the first-second shaft (2530) and the second-second shaft (2540) are non-magnetic, the first-second groove (2356) and the second-second groove (2357) can be effectively pressed against the first-second shaft (2530) and the second-second shaft (2540) by the attractive force between the first-second auxiliary magnet (2371) and the second yoke (2630) and the attractive force between the second-second auxiliary magnet (2372) and the second yoke (2630). In addition, it can be implemented by combining the modified example of FIG. 24 described above with another embodiment of FIG. 25, and various embodiments can be anticipated according to the design intention of those skilled in the art.

[0252] Meanwhile, reference may be made to FIGS. 26 and 27 to specifically explain the coupling between the first panel portion (2410) and the second panel portion (2440) and the second housing (2100), and the coupling between the first panel portion (2410) and the second panel portion (2440) and the fixed lens assembly (2200).

[0253] First, as illustrated in FIG. 26, the fixed lens assembly (2200) may include a third lens group (2210), a third barrel portion (2220), and a second-third extension portion (2230) extending in a third direction from the third barrel portion (2220). Here, the second-third extension portion (2230) may extend to both sides in the third direction. With reference to FIG. 26, it may extend to the left and right with respect to the third barrel portion (2220).

[0254] Inside the second housing (2100), a first-first shaft (2510), a first-second shaft (2530), a second-first shaft (2520), and a second-second shaft (2540) are arranged, and the first-first shaft (2510) and the second-first shaft (2520) can be in contact with the second barrel portion (2352), and the first-second shaft (2530) and the second-second shaft (2540) can be in contact with the second-third extension portion (2230). In addition, the 1-1 shaft (2510) and the 2-1 shaft (2520) may be arranged between the 2-1 extension (2323) and the 1st panel portion (2410), and the 1-2 shaft (2530) and the 2-2 shaft (2540) may be arranged between the 2-2 extension (2353) and the 2nd panel portion (2440).

[0255] At this time, the first panel portion (2410) includes a second frame (2430) extending in a third direction, the second panel portion (2440) includes a third frame (2460) extending in a third direction, and the second frame (2430) and the third frame (2460) may extend in opposite directions. In addition, the first panel portion (2410) may be arranged adjacent to one inner surface in the third direction on the inside of the second housing (2100), and the second panel portion (2440) may be arranged adjacent to the other inner surface in the third direction on the inside of the second housing (2100).

[0256] Here, the second housing (2100) is formed with a second-first protrusion (2111) and a second-second protrusion (2112) that protrude toward the second-third extension (2230) of the fixed lens assembly (2200), and the second-first protrusion (2111) can be inserted into the inside of the second-third extension (2230) by penetrating the third-first hole (2416), and the second-second protrusion (2112) can be inserted into the inside of the second-third extension (2230) by penetrating the third-2 hole (2446).

[0257] At this time, the 2-3 extension (2230) includes a third hole (2240) into which the 2-1 protrusion (2111) is inserted, and a fourth hole (2250) into which the 2-2 protrusion (2112) is inserted, and the 2-1 protrusion (2111) can have its end positioned in the third hole (2240) by penetrating the 3-1 hole (2416), and the 2-2 protrusion (2112) can have its end positioned in the 4th hole (2250) by penetrating the 3-2 hole (2446).

[0258] That is, the upper side of the first panel portion (2410) in the first direction and the upper side of the second panel portion (2440) are fixed by the second housing (2100) and the fixed lens assembly (2200), the third hole (2240) is formed so as not to be open in the first direction, the fourth hole (2250) is formed so as to be open in the first direction, and an adhesive member or a hardening member may be arranged on the inside of the fourth hole (2250). Here, the adhesive member and the hardening member may be epoxy, but may not necessarily be limited to what is mentioned.

[0259] Meanwhile, as illustrated in FIG. 27, the ends of the first-direction shaft (2510), the first-second shaft (2530), the second-first shaft (2520), and the second-second shaft (2540) can be supported by contacting the first step portion (2414a) and the second step portion (2444a). In addition, a 3-1 protrusion (2415) is formed at the lower end of the first panel portion (2410) in the first direction, a 3-2 protrusion (2445) is formed at the lower end of the second panel portion (2440) in the first direction, and a 2-1 hole (2121) and a 2-2 hole (2122) into which the 3-1 protrusion (2415) and the 3-2 protrusion (2445) are inserted are formed at the bottom surface of the second housing (2100), so that the first panel portion (2410) and the second panel portion (2440) can be fixed.

[0260] Accordingly, there may be an effect of fixing the shaking of the first panel portion (2410) and the second panel portion (2440) and preventing the shaking of the first lens assembly (2310) and the second lens assembly (2350) whose movement is guided through the first-1 shaft (2510), the first-2 shaft (2530), the second-1 shaft (2520), and the second-2 shaft (2540).

[0261] To summarize the second camera actuator (A2) according to the embodiment of the present invention, the first-1 shaft (2510) and the second-1 shaft (2520) are separated by a space formed by the first-1 region (2324) and the third-1 region (2411), so that the first lens assembly (2310) can be prevented from being twisted even when the first-1 shaft (2510) and the second-1 shaft (2520) are bent, and the first-2 shaft (2530) and the second-2 shaft (2540) are separated by a space formed by the first-2 region (2354) and the third-2 region (2441), so that the second lens assembly (2350) can be prevented from being twisted even when the first-2 shaft (2530) and the second-2 shaft (2540) are bent. In addition, there may be an advantage of increasing efficiency by effectively reducing the frictional force generated between the movement of the first lens assembly (2310) and the second lens assembly (2350) due to the above-described space.

[0262] Having described preferred embodiments of the invention, it will be apparent to those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or scope thereof, in addition to the embodiments described above.

[0263] Therefore, the above-described embodiments should be considered as illustrative rather than restrictive, and accordingly, the present invention is not limited to the above description but may be modified within the scope of the appended claims and their equivalents.
