Specific details for implementing the invention

[0012] Embodiments of the present invention will be described in detail below with reference to the drawings. However, the scope of the present invention is not limited to the embodiments presented.

[0013] For example, a person skilled in the art who understands the concept of the present invention may propose other embodiments included within the scope of the concept of the present invention through the addition, modification, or deletion of components, and such embodiments shall also be deemed to be included within the scope of the concept of the present invention.

[0014] Additionally, terms including ordinal numbers, such as "first," "second," etc., used in this specification may be used to describe various components, but said components are not limited by said terms, and said terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be named the second component, and similarly, the second component may be named the first component.

[0016] FIGS. 1a and 1b are perspective views of a portable electronic device according to an embodiment of the present invention, FIG. 2 is a reference diagram illustrating the shooting angle of a plurality of camera modules mounted on a portable electronic device according to an embodiment of the present invention, and FIG. 3 is a reference diagram illustrating the shooting screen of a plurality of camera modules mounted on a portable electronic device according to an embodiment of the present invention.

[0017] The portable electronic device (1,2) may be a portable electronic device such as a mobile communication terminal, a smartphone, or a tablet PC.

[0018] As illustrated in FIGS. 1a and 1b, a portable electronic device (1, 2) is equipped with a plurality of camera modules to photograph a subject. For example, the portable electronic device may be equipped with a first camera module (1000) and a second camera module (500).

[0019] FIG. 1a and FIG. 1b both have two camera modules, FIG. 1a is a case where the first camera module (1000) and the second camera module (500) are sequentially arranged along the width direction (relatively shorter side direction) of the portable electronic device (1, 2), and FIG. 1b is a case where the first camera module (1000) and the second camera module (500) are sequentially arranged along the length direction (relatively longer side direction) of the portable electronic device (1, 2).

[0020] When using two camera modules, the incident ports through which light enters the two camera modules can be positioned as close as possible to each other.

[0021] And, as shown in FIG. 2, the first camera module (1000) and the second camera module (500) are configured to have different viewing angles.

[0022] The first camera module (1000) is configured to have a relatively narrow field of view (e.g., a telephoto camera), and the second camera module (500) is configured to have a relatively wide field of view (e.g., a wide-angle camera). Here, the first camera module (1000) may correspond to the camera module described below with reference to FIGS. 4 to 25.

[0023] For example, the angle of view (θ1) of the first camera module (1000) can be formed in the range of 9° to 35°, and the angle of view (θ2) of the second camera module (500) can be formed in the range of 60° to 120°.

[0024] By designing the field of view of the two camera modules differently in this way, images of the subject can be captured with varying depths.

[0025] Meanwhile, a portable electronic device (1, 2) according to one embodiment of the present invention may be equipped with a Picture in Picture (PIP) function.

[0026] For example, a portable electronic device (1, 2) can display an image captured by a camera module with a narrower field of view (for example, a first camera module (1000)) within an image captured by a camera module with a wider field of view (for example, a second camera module (500)).

[0027] In other words, a subject of interest can be captured with a narrow angle of view (therefore, the subject of interest is magnified) and displayed within an image captured with a wide angle of view.

[0028] When shooting video, since the subject of interest may move, a camera module having a narrower field of view (for example, a first camera module (1000)) may be equipped with a rotating reflective module (folded module) to shoot following the movement of the subject of interest. Accordingly, light incident on the first camera module (1000) can be reflected by the reflective member of the reflective module, and after the light path is radiated, it can be incident on the lens module.

[0029] For example, the first camera module (1000) can rotate the reflection module to track the movement of the subject of interest.

[0030] For example, a reflection module provided in the first camera module (1000) can be rotated with respect to a first axis (X-axis) and a second axis (Y-axis). Accordingly, the first camera module (1000) can correct shaking that may occur during shooting.

[0031] Here, the first axis (X-axis) refers to an axis perpendicular to the optical axis (Z-axis), and the second axis (Y-axis) may refer to an axis perpendicular to both the optical axis (Z-axis) and the first axis (X-axis). Furthermore, the first axis (X-axis) and the second axis (Y-axis), which are the rotation axes of the reflection module of the first camera module (1000), may intersect the optical axis (Z-axis), and the optical axis (Z-axis), the first axis (X-axis), and the second axis (Y-axis) may meet at approximately one point.

[0032] FIG. 3 illustrates a range of subjects that can be photographed using a first camera module (1000) and a second camera module (500) installed in a portable electronic device (1, 2) according to one embodiment of the present invention.

[0033] The second camera module (500), which has a relatively large field of view, can photograph a subject with a relatively large area, and the first camera module (1000), which has a relatively small field of view, can photograph a subject with a relatively small area.

[0034] In particular, the first camera module (1000) can capture the inner area of ​​the wide imaging range (W) captured by the second camera module (500) as a tele imaging range (T1~T9), and the image (video) captured in the tele imaging range (T1~T9) in this way can be displayed inside the image (video) captured in the wide imaging range (W). Of course, the tele imaging range (T1~T9) captured by the first camera module (1000) can also capture the outer area by overlapping a part of the inner area of ​​the wide imaging range (W) with the outer area, or capture the outer area of ​​the wide imaging range (W).

[0035] Meanwhile, since the first camera module (1000) is equipped with a reflection module (folded module) that rotates based on a first axis (X-axis) and a second axis (Y-axis) that intersect the optical axis (Z-axis), the image (video) captured by the first camera module (1000) may be tilted relative to the image (video) captured by the second camera module (500) by changing the capturing angle due to the rotation of the reflection module. This is the case where the angle of T1~T3 or T6~T9 among the tele-capturing ranges illustrated in the reference diagram of FIG. 3 is changed due to the rotation of the reflection module.

[0036] Accordingly, in the case of an image (video) captured with a subject in the telephoto range T1~T3 or T6~T9 captured by the first camera module (1000), the captured image (video) can be rotated to be aligned with the captured image (video) of the second camera module (500) to implement the PIP function.

[0037] To implement these functions, the camera module (1000, 2000) or portable electronic device (1, 2) may be equipped with a control unit for editing images or implementing PIP functions.

[0039] FIG. 4 is a perspective view of a camera module according to an embodiment of the present invention, FIG. 5a and FIG. 5b are cross-sectional views of a camera module according to an embodiment of the present invention, FIG. 6 is an exploded perspective view of a camera module according to an embodiment of the present invention, FIG. 7 is a perspective view of a housing of a camera module according to an embodiment of the present invention, and FIG. 8 is a perspective view of a reflection module and a lens module coupled to the housing of a camera module according to an embodiment of the present invention.

[0040] Referring to FIGS. 4 to 8, a camera module (1000) according to one embodiment of the present invention includes a reflection module (folded module, 1100) and a lens module (1200) provided in a housing (1010).

[0041] The reflection module (1100) is configured to change the direction of light propagation. For example, light incident through the opening (1031) of the cover (1030, i.e., shield can) covering the camera module (1000) from the top can have its direction of propagation changed to head toward the lens module (1200) through the reflection module (1100). To this end, the reflection module (1100) may be provided with a reflective member (1150) that reflects light.

[0042] The reflective member (1150) may be provided with a chamfer (1153) in which the corner of the reflective member (1150) is cut to reduce light reflection or scattering.

[0043] Light incident in the thickness direction (Y-axis direction) of the camera module (1000) has its path changed by the reflection module (1100) so that it roughly coincides with the optical axis (Z-axis) direction.

[0044] To this end, the reflection module (1100) is equipped with a reflective member (1150) that reflects light. Then, light incident on the lens module (1200) passes through a plurality of lenses and can be converted into an electrical signal and stored by an image sensor (not shown).

[0045] The lens module (1200) includes a plurality of lenses through which light whose direction of travel has been changed by the reflection module (1100) passes. The lens module (1200) also has at least one lens barrel. An autofocus (AF) or zoom function (Zoom) can be implemented depending on the movement of the at least one lens barrel in the direction of the optical axis (Z-axis).

[0046] An image sensor module (not shown) may include an image sensor (not shown) that converts light passing through a plurality of lenses into an electrical signal, and a printed circuit board (not shown) on which the image sensor (not shown) is mounted.

[0047] In the internal space of the housing (1010), a reflection module (1100) may be provided in front of the lens module (1200) and an image sensor module (not shown) may be provided behind the lens module (1200).

[0048] Additionally, the housing (1010) may be provided with a baffle (1300) at the rear of the lens module (1200) to block unnecessary light that may enter the image sensor in order to reduce flare. Although only one baffle (1300) is shown in the drawing, two or more baffles (1300) may be provided.

[0049] In order to implement a telephoto camera, the focal length can be increased, and accordingly, the distance between the lens module (1200) and the image sensor can be increased.

[0050] Accordingly, a baffle (1300) that blocks unnecessary light in the internal light path of the housing (1010) may be provided. The baffle (1300) is a member fitted into the internal space of the housing (1010) and can reduce the size of the light path so that excessive reflection does not occur when light passes through the internal space of the housing (1010).

[0051] Inside the housing (1010), a reflection module (1100) and a lens module (1200) are provided sequentially from one side to the other.

[0052] For example, as illustrated in the drawing, the housing (1010) may be integrally provided so that both the reflection module (1100) and the lens module (1200) are inserted into the internal space.

[0053] By using an integrated housing (1010), there is no need to separately align the optical axes of the reflection module (1100) and the lens module (1200), and since the housing is provided as a single unit, the number of parts can be reduced, making assembly very easy.

[0054] However, this is not limited thereto, and for example, separate housings that respectively insert the reflection module (1100) and the lens module (1200) may be interconnected.

[0055] In this embodiment, the reflective member (1150) provided in the reflective module (1100) is capable of rotating within a considerably large range, such that it has a rotation angle of approximately ±10 degrees (total 20 degrees rotation possible) with respect to the first axis (X-axis) and approximately ±25 degrees (total 50 degrees rotation possible) with respect to the second axis (Y-axis).

[0056] Accordingly, the space in the housing (1010) where the reflection module (1100) is provided may be provided with a longer width, i.e., a longer length in the X-axis direction, than the space where the lens module (1200) is provided.

[0057] For example, in the housing (1010), when the width (length in the X-axis direction) of the space where the reflection module (1100) is provided is called 'A' and the width (length in the X-axis direction) of the space where the lens module (1200) is provided is called 'B', they can satisfy the mutual relationship '2 > A / B > 1'.

[0058] Light whose path has been changed by the reflection module (1100) is incident on the lens module (1200). Therefore, a plurality of lenses provided in the lens module (1200) are provided to be stacked in the Z-axis direction, which is the direction in which light is emitted from the reflection module (1100).

[0059] In addition, the lens module (1200) is equipped with a third driving unit to implement autofocus (AF), zoom function, etc.

[0060] The lens module (1200) includes a lens holder (1220) provided in a second space (1090) of the housing (1010) and including a laminated lens inside, and a third driving unit for moving the lens holder (1220).

[0061] A lens holder (1220) accommodates a plurality of lenses for capturing an object, and the plurality of lenses are mounted on the lens holder (1220) along the optical axis. The lens holder (1220) may separately provide a lens barrel in which a plurality of lenses are stacked and a carrier that encloses the lens barrel. Alternatively, a plurality of lenses may be stacked and provided on the lens holder (1220) itself.

[0062] The lens holder (1220) is configured to move in the direction of the optical axis (Z-axis) to implement autofocus or zoom functions.

[0063] The third driving unit generates a driving force to enable the lens holder (1220) to move in the direction of the optical axis (Z-axis). That is, the third driving unit can move the lens holder (1220) to change the distance between the lens holder (1220) and the reflection module (1100).

[0064] For example, the third driving unit includes a plurality of third magnets (1241a, 1243a) and a plurality of third coils (1241b, 1243b) arranged to face the plurality of third magnets (1241a, 1243a).

[0065] When power is applied to the plurality of third coils (1241b, 1243b), the lens holder (1220) equipped with the plurality of third magnets (1241a, 1243a) can be moved in the direction of the optical axis (Z-axis) by means of the electromagnetic influence between the plurality of third magnets (1241a, 1243a) and the plurality of third coils (1241b, 1243b).

[0066] A plurality of third magnets (1241a, 1243a) are mounted on the lens holder (1220). For example, a plurality of third magnets (1241a, 1243a) may be mounted on the side of the lens holder (1220).

[0067] A plurality of third coils (1241b, 1243b) are mounted in the housing (1010). For example, the plurality of third coils (1241b, 1243b) are mounted on the main board (1070), and the main board (1070) can be mounted in the housing (1010).

[0068] Here, for convenience of explanation, the drawing depicts the main board (1070) having both the coil for the reflection module (1100) and the coil for the lens module (1200) mounted thereon, but is not limited thereto, and the main board (1070) may be provided as a separate board having the coil for the reflection module (1100) and the coil for the lens module (1200) mounted thereon, respectively.

[0069] In this embodiment, when moving the lens holder (1220), a closed-loop control method is used to detect and provide feedback on the position of the lens holder (1220). Therefore, a third position detection sensor (1243c) is required for closed-loop control. The third position detection sensor (1243c) may be a Hall sensor.

[0070] The third position sensing sensor (1243c) is positioned on the inner or outer side of at least one of the third coils (1243b), and the third position sensing sensor (1243c) can be mounted on the main board (1070) on which the third coil (1243b) is mounted.

[0071] A lens holder (1220) is provided in a housing (1010) so as to be movable in the direction of the optical axis (Z-axis). For example, a plurality of third ball members (1250) are disposed between the lens holder (1220) and the housing (1010).

[0072] Multiple third ball members (1250) serve as bearings that guide the movement of the lens holder (1220). Additionally, they also function to maintain the distance between the lens holder (1220) and the housing (1010).

[0073] A plurality of third ball members (1250) are configured to perform rolling or sliding motion in the direction of the optical axis (Z-axis) when a driving force is generated in the direction of the optical axis (Z-axis). Accordingly, the plurality of third ball members (1250) guide the movement of the lens holder (1220) in the direction of the optical axis (Z-axis).

[0074] At least one of the surfaces facing each other between the lens holder (1220) and the housing (1010) has a plurality of seventh guide portions (1221) formed to accommodate a plurality of third ball members (1250).

[0075] A plurality of third ball members (1250) are received in a plurality of seventh guide members (1221) and are fitted between the lens holder (1220) and the housing (1010).

[0076] A plurality of seventh guide parts (1221, 1231) may have a shape having a length in the direction of the optical axis (Z-axis).

[0077] When a plurality of third ball members (1250) are received in a plurality of seventh guide members (1221), movement in the X-axis and Y-axis directions perpendicular to the optical axis is restricted, and movement is possible only in the optical axis (Z-axis) direction. For example, a plurality of third ball members (1250) can roll only in the optical axis (Z-axis) direction.

[0078] To this end, each of the plurality of seventh guide parts (1221) may be formed to be elongated in the direction of the optical axis (Z-axis). In addition, the cross-sections of the plurality of seventh guide parts (1221) may have various shapes, such as curved shapes or polygonal shapes.

[0079] Here, the lens holder (1220) is pressed toward the housing (1010) so that a plurality of third ball members (1250) can maintain contact with the lens holder (1220) and the housing (1010).

[0080] To this end, a third yoke (1260) may be mounted on the bottom surface of the housing (1010) so as to face a plurality of third magnets (1241a, 1243a) mounted on the lens holder (1220). The third yoke (1260) may be a magnetic material.

[0081] An attractive force acts between the third yoke (1260) and the plurality of third magnets (1241a, 1243a). Accordingly, the lens holder (1220) can be moved in the direction of the optical axis (Z-axis) by the driving force of the third driving unit while in contact with the plurality of third ball members (1250).

[0082] The lens holder (1220) is supported in the housing (1010) by the attractive force of the third yoke (1260) and a plurality of third magnets (1241a, 1243a), but accordingly, the lens holder (1220) may detach due to external force such as an external impact and come into contact with other components such as the cover (1030).

[0083] Accordingly, in this embodiment, a third auxiliary member (1280) may be provided to prevent the lens holder (1220) from moving out of position and to absorb shock even if shaking occurs due to an external force.

[0084] The third auxiliary member (1280) can perform the role of a stopper or damper, is provided in a roughly 'C' shape, and both ends can be fitted and fixed to the housing (1010) to cover the lens holder (1220) from the top.

[0085] Additionally, the third auxiliary member (1280) may be further equipped with damping members of an elastic material in various parts to absorb shock. For example, during the movement of the lens holder (1220) in the direction of the optical axis, the front or rear end in the direction of the optical axis may come into contact with the third auxiliary member (1280), and at this time, dampers (1283) may be provided at both ends of the third auxiliary member (1280) to absorb shock.

[0086] Two third auxiliary members (1280) may be provided so as to be installed on each side of the lens holder (1220).

[0088] The housing (1010) is covered by a cover (1030).

[0089] The cover (1030) is provided with an opening (1031) for light to be incident, and the light incident through the opening (1031) has its direction of travel changed by the reflection module (1100) and is incident on the lens module (1200). The cover (1030) may be provided integrally to cover the entire housing (1010), or it may be provided as separate members that cover the reflection module (1100) and the lens module (1200), respectively.

[0090] The opening (1031) provided in the cover (1030) may be provided in a roughly hexagonal shape. The reflection module (1100) according to the present embodiment is capable of rotating around the second axis (Y-axis), and accordingly, when the reflection member (1150) is rotated to the maximum around the second axis (Y-axis), the short edge of the reflection member (1150) and the side of the cover (1030) may be arranged roughly parallel to each other.

[0091] Referring further to FIG. 7, the housing (1010) is provided with a reflection module (1100) and a lens module (1200) in its internal space. Accordingly, the internal space of the housing (1010) can be divided into a first space (1080) where the reflection module (1100) is placed and a second space (1090) where the lens module (1200) is placed.

[0092] The first space (1080) in which the reflection module (1100) is placed in the housing (1010) may be provided with an internal space having a round shape to facilitate rotation of the carrier (1110) that rotates in a large circle.

[0093] And, since a plurality of coils (1114, 1134, 1241b, 1243b) are mounted on the main board (1070) and provided in the housing (1010), a plurality of through holes (1010a, 1010b, 1010c, 1010d) may be provided in the housing (1010) so that a plurality of coils (1114, 1134, 1241b, 1243b) are exposed to the internal space of the housing (1010).

[0095] FIG. 9 is an exploded perspective view of a housing and a reflector module of a camera module according to one embodiment of the present invention, FIG. 10a is a detailed upper exploded perspective view of a housing and a reflector module of a camera module according to one embodiment of the present invention, and FIG. 10b is a detailed lower exploded perspective view of a housing and a reflector module of a camera module according to one embodiment of the present invention.

[0096] Referring further to FIGS. 9 to 10b, the reflection module (1100) comprises a carrier (1110) provided in a housing (1010) and a rotating holder (1130) provided in the carrier (1110).

[0097] The carrier (1110) rotates about the second axis (A2, an axis parallel to the Y-axis) with respect to the housing (1010), and the rotation holder (1130) rotates about the first axis (A1, an axis parallel to the X-axis) with respect to the carrier (1110).

[0098] Referring further to FIGS. 14 to 19, a carrier (1110) is provided in the first space (1080) of the housing (1010). The carrier (1110) is supported in close contact with the bottom surface of the housing (1010) with a first ball member (1111) inserted between them, and the carrier (1110) is rotated by a first driving unit. The first space (1080) may be provided with at least a portion having a rounded shape to facilitate the large rotation of the carrier (1110). More specifically, the inner surface of the first space (1080) may be provided with at least a portion corresponding to the arc shape of a circle centered on the second axis (A2).

[0099] Additionally, the carrier (1110) may be provided with at least a portion having a rounded shape to facilitate rotation in the first space (1080). More specifically, at least a portion of the carrier (1110) may be provided to correspond to an arc shape of a circle centered on the second axis (A2).

[0100] Furthermore, the rotating holder (1130) placed on the carrier (1110) may be provided with at least a portion having a rounded shape to facilitate large rotation in the first space (1080). More specifically, at least a portion of the rotating holder (1130) may be provided to correspond to an arc shape of a circle centered on the second axis (A2).

[0101] The first driving unit includes a first magnet (1113) and a first coil (1114).

[0102] Accordingly, a first yoke (1112) is provided on the bottom surface of the housing (1010), and the first yoke (1112) causes the carrier (1110) to be in close contact with the bottom surface of the housing (1010) by means of an attractive force with a first magnet (1113) provided on the carrier (1110).

[0103] At least three first ball members (1111-1111a, 1111b, 1111c) may be provided between the bottom surface of the housing (1010) and the carrier (1110).

[0104] One of these, the rotational axis ball (1111a), forms a second axis (A2, an axis parallel to the Y-axis) which is a rotational axis through which the carrier (1111) rotates relative to the housing (1010), and other ball members, the guide balls (1111b, 1111c), can help facilitate the rotation of the carrier (1110).

[0105] Here, the second axis (A2) may be perpendicular to a plane containing a triangle connecting three first ball members (1111-1111a, 1111b, 1111c).

[0106] Since the rotational ball (1111a) must form a rotational axis, it can rotate in place or be fixed in place without changing its position. Accordingly, the carrier (1111) can rotate around the rotational ball (1111a) as an axis.

[0107] Guide balls (1111b, 1111c) are provided at a location other than the axis of rotation to guide the rotation of the carrier (1111), so they can be provided to move by rolling or sliding. Accordingly, the movement of the carrier (1111) can be guided by the rolling or sliding of the guide balls (1111b, 1111c).

[0108] Accordingly, a guide portion (e.g., a guide portion, etc.) into which a rotating shaft ball (1111a) is inserted is provided on the bottom surface of the housing (1010) and the lower surface of the carrier (1110).

[0109] A first guide portion (1121a) may be provided in the housing (1010) to allow the rotational ball (1111a) to be inserted, and a second guide portion (1121b) may be provided in the carrier (1110). Since the spherical rotational ball (1111a) must not be moved, at least one of the first guide portion (1121a) and the second guide portion (1121b) may be supported at least three times with respect to the rotational ball (1111a).

[0110] For example, the first guide part (1121a) and the second guide part (1121b) may be provided in a shape in which each corner of a triangular pyramid (tetrahedron) shape is cut off, as shown in FIG. 16a and FIG. 16b. This will be described later.

[0111] Alternatively, the rotating ball (1111a) may be fixedly provided in either the housing (1010) or the carrier (1110), and may be provided with a guide portion that is not positioned in the other of the housing (1010) or the carrier (1110).

[0112] A third guide section (1123a) may be provided in the housing (1010) and a fourth guide section (1123b) may be provided in the carrier (1110) so that guide balls (1111b, 1111c) can be inserted. Since it is preferable for the spherical guide balls (1111b, 1111c) to be movable, the third guide section (1123a) and the fourth guide section (1123b) may be provided in a long manner along the rotational direction of the carrier (1110).

[0113] In this embodiment, the third guide part (1123a) and the fourth guide part (1123b) may be provided in a straight line along the direction of rotation.

[0114] When the third guide section (1123a) and the fourth guide section (1123b) are provided in a straight line shape, either the third guide section (1123a) or the fourth guide section (1123b) may be provided to have an additional degree of freedom. This is because if the guide balls (1111b, 1111c) are provided to move only in a straight line direction, the guiding may not be properly performed since they support the rotating carrier (1110).

[0115] For example, as shown in FIG. 17a and FIG. 17b, the third guide section (1123a) and the fourth guide section (1123b) can each be optionally configured such that one includes a side of a 'V'-shaped or 'U'-shaped groove, thereby supporting the guide ball (1111b, 1111c) at least two points, and the other supports the guide ball (1111b, 1111c) at one point on a roughly flat bottom surface without contacting the side of the groove.

[0116] Accordingly, within the guide section that is supported only at one point on the bottom surface without contacting the side of the home, there is no lateral constraint, so the ball can move left and right along the bottom surface, thus having additional degrees of freedom, so even if the carrier (1110) rotates, the rolling of the guide ball (1111b, 1111c) can be smooth.

[0117] Referring to FIG. 17a, a rotating part (1110) that rotates relative to a fixed part (1010) with respect to a rotation axis can be guided by guide balls (1111b, 1111c). The guide balls (1111b, 1111c) may include a third guide part (1123a) and a fourth guide part (1123b) that are provided in a straight line along the direction of rotation. Here, the third guide part (1123a) provided in the housing, which is the fixed part (1010), has a bottom surface (26a) and two side surfaces (25a), and the guide balls (1111b, 1111c) can be supported at least two points on both side surfaces (25a) (they may also be supported up to the bottom surface (26a)).

[0118] In addition, the fourth guide part (1123b) provided in the carrier, which is the rotating part (1110), is provided with a bottom surface (26b) and two side surfaces (25b), and the guide balls (1111b, 1111c) can be supported at one point on the bottom surface (26a). When the guide balls (1111b, 1111c) come into contact with either of the two side surfaces (25b), the guide balls (1111b, 1111c) can no longer roll, so the two side surfaces (25b) can act as stoppers.

[0119] In this way, the guide ball (1111b, 1111c) is supported at least two points in the third guide section (1123a) provided in the fixed section (1010) and moves in a straight line along a predetermined path of the guide section, and is supported at one point on the bottom surface in the fourth guide section (1123b) provided in the rotating section (1110), and the guide ball (1111b, 1111c) supported at one point forms a curved movement path on the bottom (26b) of the guide section of the rotating section (1110) according to the movement of the carrier, which is the rotating section (1110).

[0120] Additionally, referring to FIG. 17b, a rotating part (1110) that rotates relative to a fixed part (1010) with respect to a rotation axis can be guided by guide balls (1111b, 1111c). The guide balls (1111b, 1111c) may include a third guide part (1123a-1) and a fourth guide part (1123b-1) that are provided in a straight line along the direction of rotation.

[0121] Here, the third guide part (1123a-1) provided in the housing, which is the fixed part (1010), has a bottom surface (26a-1) and two side surfaces (25a-1), and the guide balls (1111b, 1111c) can be supported at one point on the bottom surface (26a-1). When the guide ball (1111b, 1111c) comes into contact with either of the two sides (25a-1), the guide ball (1111b, 1111c) can no longer roll, so the two sides (25a-1) can act as stoppers. Also, the fourth guide part (1123b-1) provided on the carrier, which is the rotating part (1110), has a bottom surface (26b-1) and two sides (25b-1), and the guide ball (1111b, 1111c) can be supported at least two points on the two sides (25b-1) (it may also be supported up to the bottom surface (26b-1)).

[0122] In this way, the guide ball (1111b, 1111c) is supported at least two points in the fourth guide section (1123b-1) provided in the rotating section (1110) and moves linearly along a predetermined path of the guide section, and is supported at one point on the bottom surface in the third guide section (11231-1) provided in the fixed section (1010), and the guide ball (1111b, 1111c) supported at one point forms a curved movement path on the bottom (26a-1) of the guide section of the fixed section (1010) according to the movement of the carrier, which is the rotating section (1110).

[0124] Referring further to FIGS. 18 to 20, a first coil (1114) is provided on the bottom of the housing (1010), and a first magnet (1113) is provided on the carrier (1110) facing the first coil (1114). In addition, to detect the rotational position of the carrier (1110), a first position sensing sensor (1115) may be provided on the housing (1010) facing the first magnet (1113).

[0125] The first magnet (1113) may be provided in a rounded shape to account for the rotational movement of the carrier (1110). The inner end and outer end of the first magnet (1113) may be provided in the shape of a circle arc, and more specifically, the inner end and outer end of the first magnet (1113) may be provided to correspond to the shape of a circle arc centered on the rotational axis ball (1111a).

[0126] For example, the first magnet (1113) may be provided in a shape that is partially cut out of a donut. Also, the first magnet (1113) may be provided to have an N pole and a S pole along the direction of rotation.

[0127] The carrier (1110) may further be provided with a back yoke (1113a) that focuses magnetism on the back side of the first magnet (1113), that is, between the carrier (1110) and the first magnet (1113), thereby maintaining or further improving the performance of the first magnet (1113). Considering that the first magnet (1113) has a rounded shape, the back yoke (1113a) may be provided larger in a shape facing the first magnet (1113).

[0128] Also, the first coil (1114) may be positioned at a location corresponding to the first magnet (1113). The first coil (1114) may be provided as one or two or more, and the first coil (1114) may be arranged in a round shape or a bent shape corresponding to the shape of the first magnet (1113). For example, if the first coil (1114) is provided as two, it may be arranged to form an overall bent shape, that is, a 'V' shape.

[0129] For example, when the first magnet (1113) is magnetized in three poles of ‘N pole, S pole, N pole’ or ‘S pole, N pole, S pole’ along the rotational direction of the carrier (1110), the first coil (1114) may be provided in two, and each coil may be arranged to face the poles at the middle and left and right ends simultaneously.

[0130] That is, in the case of an electronic 'N pole, S pole, N pole' magnet, one of the two first coils (1114) can be positioned so that it faces the left half of the N pole and the middle S pole, and the other can be positioned so that it faces the right half of the N pole and the middle S pole.

[0131] Of course, the first magnet (1113) may be provided with two magnets separated into two poles each, and may be arranged to face each of the two first coils (1114). In this case, the first magnet (1113) may have a rounded (round) shape or a straight shape.

[0132] Meanwhile, the first magnet (1113) may be provided between the first ball members (1111-1111a, 1111b, 1111c). More specifically, the first magnet (1113) may be positioned between the rotational axis ball (1111a) and the guide balls (1111b, 1111c).

[0133] The first ball members (1111-1111a, 1111b, 1111c), that is, one rotational axis ball (1111a) and two guide balls (1111b, 1111c), can be arranged in a triangular shape.

[0134] The center of gravity or geometric center of the first magnet (1113) may be provided within the triangle formed by the first ball members (1111-1111a, 1111b, 1111c). The carrier (1110) is in close contact with the housing (1010) by the attractive force between the first yoke (1112) and the first magnet (1113), and this is to prevent the carrier (1110) from tilting to one side due to the attractive force generated at this time.

[0135] Meanwhile, since the center of gravity or geometric center of the first magnet (1113) is located inside the triangle formed by the first ball members (1111-1111a, 1111b, 1111c), when the power supply to the reflection module (1100) is interrupted, the carrier (1110) can move to the initial position by the attractive force between the first magnet (1113) and the first yoke (1112).

[0136] The initial position can be adjusted according to the arrangement of the first magnet (1113) and the first yoke (1112). For example, in the case of the present embodiment, a position in which the reflective member (1150) is aligned parallel to the optical axis direction is preferred.

[0137] Two first coils (1114) facing the first magnet (1113) can also be placed between the rotational axis ball (1111a) and the guide balls (1111b, 1111c).

[0138] In addition, a first position detection sensor (1115) for detecting the position of the carrier (1110) may be positioned opposite the first magnet (1113). The first position detection sensor (1115) may be a Hall sensor. One or more first position detection sensors (1115) may be provided for more accurate position detection of the carrier (1110).

[0139] The first position sensing sensor (1115) can be provided between the first coil (1114) and the rotation axis ball (1111a) when viewed in a planar view. In the case of a rotating carrier (1110), the further it is from the rotation axis (1111a), the longer the travel distance becomes. Considering that the carrier (1110) of this embodiment rotates a large number of times (rotation angle approximately ±25 degrees), the further it is from the rotation axis ball (1111a) forming the rotation axis, the longer the travel distance becomes, so a large number of position sensing sensors may be required.

[0140] Accordingly, in this embodiment, the first position sensing sensor (1115) can be placed on the inner side of the first coil (1114), that is, at a position close to the rotation axis ball (1111a) that forms the rotation axis.

[0141] Meanwhile, the housing (1010) may be provided with a first yoke (1112) facing the first magnet (1113). The first yoke (1112) can serve as a pulling yoke that brings the carrier (1110) into close contact with the housing (1010).

[0142] Additionally, the first yoke (1112) may be provided in the housing (1010) to surround (close) the first coil (1114), thereby preventing magnetic field (magnetic) leakage from the first magnet (1113) or the first coil (1114).

[0143] Since the first yoke (1112) brings the carrier (1110) into close contact with the housing (1010) by means of an attractive force with the first magnet (1113), the first yoke (1112) may be provided with a shape similar to the first magnet (1113) and may face the first magnet (1113) with the first coil (1114) in between.

[0144] That is, the first yoke (1112) can be provided in a rounded shape, which is a shape of a donut partially cut, and can be provided larger than the first magnet (1113) and the first coil (1114) while encircling them.

[0146] Referring further to FIGS. 11 to 13, a carrier (1110) is provided with a rotating holder (1130). A reflective member (1150) is provided in the rotating holder (1020), and the rotating holder (1130) is rotated by a second driving unit. The second driving unit includes a second magnet (1133) and a second coil (1134).

[0147] The reflective member (1150) can change the direction of light propagation. For example, the reflective member (1150) may be a mirror or a prism that reflects light (for convenience of explanation, the reflective member (1150) is depicted as a prism in the drawings related to one embodiment).

[0148] The reflective member (1150) is fixed to the rotating holder (1130). The rotating holder (1130) is provided with a mounting surface (1136) on which the reflective member (1150) is mounted.

[0149] The mounting surface (1136) of the rotating holder (1130) may be configured as an inclined surface to change the path of light. For example, the mounting surface (1136) may be an inclined surface tilted 30 to 60 degrees with respect to the optical axis (Z-axis) of a plurality of lenses. The inclined surface of the rotating holder (1130) may face the opening (1031) of the cover (1030) into which light is incident.

[0150] Additionally, on the mounting surface (1136), a plurality of protrusions (1136a) may be provided toward the reflective member (1150) at the end facing the lens module (1200) in the direction of the optical axis to reduce the occurrence of flare caused by light reflection, diffraction, etc.

[0151] The end of the projection (1136a) may be formed to be pointed, and the projection (1136a) may be provided over a certain area of ​​the end portion of the mounting surface (1136).

[0152] The rotating holder (1130) can be closely supported with two second ball members (1131) inserted between it and the carrier (1110).

[0153] Accordingly, the rotating holder (1130) and the carrier (1110) are each optionally provided with a first magnetic body (1138) and a second magnetic body (1132), and the rotating holder (1130) is made to be in close contact with the carrier (1110) by the attractive force of the first magnetic body (1138) and the second magnetic body (1132).

[0154] In the case where the first magnetic body (1138) is a magnet, that is, the fourth magnet (1138), a back yoke may be further provided on the back of the fourth magnet (1138) to concentrate magnetism and maintain or further improve the performance of the fourth magnet (1138).

[0155] And, as illustrated in detail in FIG. 20, when the fourth magnet (1138) is provided on the carrier (1110), the back yoke (1113a) can be used in common. That is, the carrier (1110) is provided with a back yoke (1113a) that focuses the magnetism of the first magnet (1113) to maintain or further improve the performance of the first magnet (1113), and the back yoke (1113a) can be provided with a length that is slightly extended so that it covers the back of the fourth magnet (1138). Accordingly, the back yoke (1113a) may be provided with an extension part (1113b) that extends to the back of the fourth magnet (1138).

[0156] Here, a reflection module (folded module, 400) according to one embodiment of the present invention may optionally be provided with a first magnetic body (1138) and a second magnetic body (1132) on a carrier (1110) and a rotating holder (1130). Additionally, the rotating holder (1130) may be provided to be supported on the carrier (1110) by the attractive force between the first magnetic body (1138) and the second magnetic body (1132). The first magnetic body (1138) and the second magnetic body (1132) may be provided facing each other in the direction of the second axis (A2). Since the reflection module (folded module, 400) according to the present embodiment has a structure in which the rotating holder (1130) is placed on the upper part of the carrier (1110), it is preferable for the rotating holder (1130) to be supported toward the carrier (1110) for driving stability.

[0157] Here, the first magnetic body (1138) or the second magnetic body (1132) is a magnetic substance or magnetic material, which is a material that possesses magnetism, that is, a material that becomes magnetized in a magnetic field (including both metallic and non-metallic materials). The first magnetic body (1138) or the second magnetic body (1132) may be a pulling magnet or a pulling yoke.

[0158] For example, if the first magnetic body (1138) is a pulling magnet, the second magnetic body (1132) may be a pulling yoke or a pulling magnet. Also, if the first magnetic body (1138) is a pulling yoke, the second magnetic body (1132) may be a pulling magnet.

[0159] And, the rotation holder (1130) rotates relative to the carrier (1110) with respect to the first axis (an axis parallel to the X-axis) connecting the two second ball members (1131).

[0160] Accordingly, the carrier (1110) may be provided with two first support members (1141) on both sides in the X-axis direction, and the rotating holder (1130) may be provided with two second support members (1143) on both sides in the X-axis direction that are placed on the first support members (1141).

[0161] A second ball member (1131) may be provided between a pair of first support members (1141) and second support members (1143) provided on both sides. Additionally, the two second ball members (1131) may be parallel to the X-axis and form a first axis (A1) which is the rotation axis of the rotation holder (1130).

[0162] Since the two second ball members (1131) must form a rotation axis, they can rotate in place or be fixed while remaining fixed in one place without changing their position. Accordingly, the rotation holder (1130) can rotate around the first axis (A1) formed by the two second ball members (1131).

[0163] Accordingly, the first support member (1141) and the second support member (1143) are provided with a guide member (e.g., a guide member, etc.) into which the second ball member (1131) is inserted.

[0164] A fifth guide part (1141a) may be provided in the first support part (1141) of the carrier (1110) so that the second ball member (1131) can be inserted, and a sixth guide part (1143a) may be provided in the second support part (1143) of the rotation holder (1130).

[0165] Since the spherical second ball member (1131) must not be moved, at least one of the fifth guide part (1141a) and the sixth guide part (1143a) can be supported at least three times with the second ball member (1131). Here, the rotational axis ball (1111a) may be fixedly provided in either the housing (1010) or the carrier (1110), and a guide part that is not moved may be provided in the other of the housing (1010) or the carrier (1110).

[0166] For example, FIGS. 16a and FIGS. 16b are reference drawings illustrating an example of a structure in which a ball member of a camera module according to one embodiment of the present invention is fixed to a guide portion by being supported at three points.

[0167] Referring to FIGS. 16a and 16b, the ball member (1111a, 1131) forming the rotation axis cannot move its position, so its position can be fixed by a three-point support structure.

[0168] The ball member (1111a, 1131) can be inserted into the guide member (1121a, 1121b, 1141a, 1143a).

[0169] In addition, to maintain an accurate position inside the guide section, the ball member inserted into the guide section can maintain a supported state by contacting the guide section at only three points (P).

[0170] When the ball member contacts the guide member at four or more points, it may be driven in a skewed state, such as forming contact at only three points, depending on the manufacturing tolerance or driving state of the guide member or the ball member.

[0171] To this end, the guide portions (1121a, 1121b, 1141a, 1143a) may be provided in a shape in which each corner is cut off from a triangular pyramid (tetrahedron) shape.

[0172] The ball member (1111a, 1131), which is spherical in shape, is supported at three points (P) on the inner side surface of the guide member (1121a, 1121b, 1141a, 1143a), and the guide member (1121a, 1121b, 1141a, 1143a) includes three first surfaces (21). Therefore, the three contact points (P) of the ball member (1111a, 1131) and the guide member (1121a, 1121b, 1141a, 1143a) are formed on the first surfaces (21).

[0173] Here, the first surface (21) is part of the side surface, and the side surface includes the first surface (21) that the ball member (1111a, 1131) contacts and the second surface (23) that is provided between the first surfaces (21) (i.e., provided adjacent to two of the first surfaces) and does not contact the ball member (1111a, 1131).

[0174] In addition, a triangular pyramid (tetrahedron) can be realized by extending the three side surfaces (first surface, 21) that are point-contacted with the ball members (1111a, 1131). That is, the line segment formed by the intersection of the three side surfaces that are point-contacted with the ball members (1111a, 1131) can realize the edge of the triangular pyramid (tetrahedron). In addition, the triangular pyramid realized by extending the three side surfaces may be an equilateral triangular pyramid.

[0175] Meanwhile, the guide portions (1121a, 1121b, 1141a, 1143a) may be provided in a shape formed by cutting off each vertex of a triangular pyramid (tetrahedron) shape.

[0176] The portion of the inner tip of the guide portion of the triangular pyramid can form the bottom (10) of the guide portion (1121a, 1121b, 1141a, 1143a), and the portion of the remaining three tips on the entrance side of the guide portion can form a second surface (23) that does not come into contact with the ball member (1111a, 1131) among the side surfaces.

[0177] Since the bottom (10) and the second surface (23) are both formed by cutting off the vertices of a triangular pyramid, they may all be triangular in shape, and the ball member (1111a, 1131) does not come into contact with the bottom (10) and the second surface (23). In addition, the entrances of the guide parts (1121a, 1121b, 1141a, 1143a) may be hexagonal in shape, as they are formed by cutting off all the vertices from the triangular bottom of a triangular pyramid (tetrahedron).

[0178] Meanwhile, the bottom of the guide section (1121a, 1121b, 1141a, 1143a) may be triangular in shape.

[0180] A second coil (1134) is provided on the side of the housing (1010), and a second magnet (1133) is provided on the rotating holder (1130) facing the second coil (1134). Additionally, to detect the rotational position of the rotating holder (1130), a second position detection sensor (1135) may be provided on the housing (1010) facing the second magnet (1133).

[0181] The second magnet (1133) can be magnetized to have an N pole and a S pole in the direction of the second axis (A2) perpendicular to the first axis (A1), and the rotation holder (1130) can rotate with respect to the carrier (1110) with respect to the first axis (A1) by means of the interaction between the second magnet (1133) and the second coil (1134).

[0182] Here, the side of the housing (1010) equipped with the second coil (1134) may mean a side perpendicular to the optical axis.

[0183] Considering that the rotating holder (1130) is provided on a carrier (1110) that rotates, it may have a rounded end portion. Additionally, the second magnet (1133) may be provided on the rounded end portion of the rotating holder (1130) opposite to the direction in which the reflective member (1150) is installed. Accordingly, the second magnet (1133) may also be provided in a rounded shape. The inner end and outer end of the second magnet (1133) may be provided in the shape of a circle arc, and more specifically, the inner end and outer end of the second magnet (1133) may be provided to correspond to the shape of a circle arc centered on the rotational axis ball (1111a).

[0184] The rotating holder (1130) may further be provided with a back yoke (1133a) that focuses magnetism on the back side of the second magnet (1133), that is, between the rotating holder (1130) and the second magnet (1133), thereby maintaining or further improving the performance of the second magnet (1133). The back yoke (1133a) may be provided larger in a shape corresponding to the second magnet (1133), taking into account that the second magnet (1133) has a rounded shape.

[0185] The second coil (1134) can also be placed at a position corresponding to the second magnet (1133).

[0186] The second coil (1134) may be provided in one or more than two places, and the second coil (1134) may be arranged in a round shape or a bent shape corresponding to the shape of the second magnet (1133). For example, the second coil (1134) may be provided in two places, with each of the two coils (1134) placed on both sides facing the second magnet (1133), and when the second coil (1114) is provided in two places, it may be arranged to form an overall bent shape, that is, a 'V' shape.

[0187] Of course, the second magnet (1133) may be provided with two separate magnets and arranged to face each of the two first coils (1134). In this case, the second magnet (1133) may have a rounded (round) shape or a straight shape.

[0188] The second magnet (1133) may be provided at the end portion furthest from the first axis (A1), which is the rotation axis of the rotation holder (1130). That is, it may be provided at the end portion with a rounded shape.

[0189] The second yoke (1132) and the fourth magnet (1138) each perform the role of a pulling yoke and a pulling magnet, and they may optionally be provided in a rotating holder (1130) or a carrier (1110). The second yoke (1132) and the fourth magnet (1138) may each be provided in one or more than two numbers so as to face each other in the Y-axis direction.

[0190] Also, since the rotation holder (1130) rotates relative to the carrier (1110) while being supported by it, it is preferable that the second yoke (1132) and the fourth magnet (1138), which are positioned opposite each other, be provided in a position that does not interfere with the rotation of the rotation holder (1130).

[0191] Accordingly, in this embodiment, two second yoke (1132) and two fourth magnets (1138) may each be provided at the lower part of the first axis (A1) so as to be very close to the rotation axis (A1) to exert sufficient pulling force while minimizing interference with the rotation of the rotation holder (1130). Accordingly, the first axis (A1), the second yoke (1132), and the fourth magnet (1138) may be aligned in the Y-axis direction and may be provided at approximately the same position in the optical axis (Z-axis) direction (see FIG. 21).

[0192] A second position sensing sensor (1135) for detecting the position of the rotating holder (1130) may be positioned opposite the second magnet (1133). The second position sensing sensor (1135) may be a Hall sensor. One or more second position sensing sensors (1135) may be provided for more accurate position detection of the rotating holder (1130).

[0193] The second position sensing sensor (1135) may be provided vertically between the two second coils (1134).

[0194] Meanwhile, the carrier (1110) may be provided with two first support members (1141) protruding on both sides in the X-axis direction, and the rotating holder (1130) may be provided with two second support members (1143) placed on the first support members (1141) on both sides in the X-axis direction.

[0195] Here, the first support member (1141) is provided with an open top shape, and a structure can be formed in which the second support member (1143) is fitted into the first support member (1141) from top to bottom.

[0196] Additionally, the carrier (1110) may further be provided with a first auxiliary member (1160) that covers the open upper portion of the first support member (1141). Since the second support member (1143) rotates, the first auxiliary member (1160) may not be in close contact with the second support member (1143) and may have a slight gap so as not to interfere with this rotation.

[0197] The first auxiliary member (1160) can act as a stopper that prevents the rotating holder (1130) from coming off the carrier (1110), or as a cushioning member that absorbs the impact of the second support member (1143) hitting another part due to displacement.

[0198] The first auxiliary member (1160) can be fitted into the carrier (1110) through the side so as to cover the second support member (1143) from the top when the second support member (1143) is coupled to the first support member (1141). Accordingly, the carrier (1110) may be provided with a slit-shaped coupling member (1142) to allow the first auxiliary member (1160) to be inserted.

[0199] The first auxiliary member (1160) may be provided with a 'U'-shaped main body (1161) to be firmly connected, and a bent portion (1163) at the end to prevent detachment. Additionally, the main body (1161) may include a fixing portion (1161a) that is partially fitted into a carrier (1110), and a damping portion (1161b) that is positioned on the upper part of the second support portion (1143) to which a damping member (1165) is connected.

[0200] The damping member (1165) is provided with a damping projection (1165a) that protrudes toward the second support member (1143), and the damping projection (1165a) may be provided facing the second ball member (1131) provided on the second support member (1143). Depending on the structure provided with the damping projection (1165a), the damping or stopping function of the rotating holder (1130) can be efficiently performed.

[0201] Additionally, the damping member (1165) may further be provided with a cushioning projection (1165b) that protrudes toward the cover (1030).

[0202] Furthermore, in this embodiment, when the rotating holder (1130) is detached from the carrier (1110), the end portion of the rotating holder (1130), that is, the upper portion of the round part where the second magnet (1133) is installed, may also come into contact with the inner wall of the cover (1030).

[0203] Accordingly, the present embodiment may be provided with a second auxiliary member (1040) to prevent the end portion of the rotating holder (1130) from hitting the cover (1030) or to absorb the impact.

[0204] The second auxiliary member (1040) is provided in a 'U' shape, and its end portion can be fitted and fixed to the side of the housing (1010). Additionally, the second auxiliary member (1040) may be provided with an additional cushioning member (1043) between it and the rotating holder (1130) or between it and the cover (1030) to facilitate shock absorption.

[0205] A second ball member (1131) may be provided between the first support member (1141) and the second support member (1143). Additionally, the two second ball members (1131) provided on both sides may form a first axis (A1) that is parallel to the X-axis direction and serves as the rotation axis of the rotation holder (1130).

[0206] Since the two second ball members (1131) must form a rotation axis, they can rotate in place or be fixed while remaining fixed in one place without changing their position. Accordingly, the rotation holder (1130) can rotate around the first axis (A1) formed by the two second ball members (1131).

[0207] Accordingly, the first support member (1141) and the second support member (1143) are provided with a guide member (e.g., a guide member, etc.) into which the second ball member (1131) is inserted.

[0208] A fifth guide part (1141a) may be provided in the first support part (1141) of the carrier (1110) so that the second ball member (1131) can be inserted, and a sixth guide part (1143a) may be provided in the second support part (1143) of the rotation holder (1130).

[0210] FIG. 21 is a reference diagram for explaining the positional relationship of two axes on which a reflection module rotates in a camera module according to one embodiment of the present invention.

[0211] Referring to FIG. 21, a reflection module (1100) according to one embodiment of the present invention may be configured such that a reflection member (1150) rotates about two axes.

[0212] A carrier (1110) provided in a housing (1010) can rotate around a first axis (A1) formed by a rotational ball (1111a), and a rotational holder (1130) provided in the carrier (1110) can rotate around a second axis (A2) formed by a second ball member (1131).

[0213] Accordingly, the reflective member (1150) provided in the rotating holder (1130) can rotate with respect to the first axis (A1) and the second axis (A2). In the illustration of the drawing, the portion shown with a dotted line includes the rotating holder (1130), and the rotating holder (1130) can rotate with respect to the first axis (A1). Also, the portion shown with a solid line includes the carrier (1110), and the carrier (1110) can rotate with respect to the second axis (A2).

[0214] The first axis (A1) and the second axis (A2) intersect each other, and the rotational axis ball (1111a) forming the second axis (A2) and the two ball members (1131) forming the first axis (A1) can be arranged to be provided on a plane where both the first axis (A1) and the second axis (A2) are provided. In other words, when viewed in the direction in which light is incident, that is, the direction of the second axis (A2), the rotational axis ball (1111a) and the two ball members (1131) can be aligned in the direction of the first axis (A1) perpendicular to the optical axis.

[0215] In the reflection module (1100) according to the present embodiment, the intersection point of the first axis (A1) and the second axis (A2) can be formed at the approximate center of the mounting surface (1136) on which the reflection member (1150) is mounted. That is, the first axis (A1) is formed along the mounting surface (1136) in a direction parallel to the X-axis direction, and the second axis (A2) can be provided to penetrate the approximate center of the mounting surface (1136).

[0216] A reflective member (1150) is mounted on the mounting surface (1136), and since the approximate center of the mounting surface (1136) can substantially correspond to the center of the reflective surface, if the intersection point of the first axis (A1) and the second axis (A2) is formed at the approximate center of the mounting surface (1136), the actual amount of rotation of the rotating holder (1130) will roughly match the amount of rotation of the reflective surface, that is, the mounting surface (1136), so that control such as shaking correction or tracking can be very easy.

[0218] FIGS. 22a and FIGS. 22b are drawings for explaining the shape of an opening of a cover (cover member) in a camera module according to one embodiment of the present invention.

[0219] The cover (1030) of the present embodiment has an opening (1031) into which light is incident, and the opening (1031) may be approximately hexagonal.

[0220] The carrier (1110) of the reflection module (1100) rotates with respect to a second axis (A2) parallel to the direction in which light is incident on the camera module (1000) (Y-axis direction), and the rotation angle is formed to be very large, approximately ±25 degrees (deg).

[0221] Therefore, the opening (1031) is provided in a roughly hexagonal shape so as to sufficiently receive incident light while reducing the incidence of unnecessary light.

[0222] That is, when the carrier (1110) rotates with respect to the housing (1010) with respect to the second axis (A2), the reflector (1150) rotates, and the angle of the corner portion changes slightly out of alignment with the optical axis direction (Z-axis direction). Accordingly, considering the maximum rotation angle of the reflector (1150), the side of the incident port located on the side direction of the housing (1010) can be formed approximately parallel to the corner of the reflector (1150).

[0223] FIG. 22a illustrates the shape of the reflective member (1150) when it is rotated maximum clockwise around the second axis (A2), and FIG. 22b illustrates the shape of the reflective member (1150) when it is rotated maximum counterclockwise around the second axis (A2).

[0225] FIG. 23 is a perspective view of an integrated substrate installed in a camera module according to one embodiment of the present invention, and FIG. 24 is a perspective view showing the integrated substrate installed in the housing of a camera module according to one embodiment of the present invention.

[0226] A main board (1070) according to one embodiment of the present invention may be provided as an integral form. In addition, coils (1114, 1134) for driving the reflection module (1100) of the first and second driving units and a plurality of coils (1241b, 1243b) for driving the lens module (1200) of the third driving unit may be mounted on the inner surface of the main board (1070). In addition, various components such as passive and active components (not shown), and a gyro sensor (not shown) may be mounted on the outer surface. Accordingly, the main board (1070) may be a double-sided board.

[0227] Additionally, the main board (1070) can be coupled to the housing (1010). Since the main board (1070) is integrated and the coils of the driving unit are all mounted on it and coupled to the housing (1010), assembly can be very easy.

[0229] FIG. 25 is a reference diagram illustrating two lens barrels of a camera module according to another embodiment of the present invention, and FIG. 26 is a reference diagram illustrating three lens barrels of a camera module according to another embodiment of the present invention.

[0230] Referring to FIG. 25, a camera module (1001) according to another embodiment of the present invention may include a reflection module (1100) and a lens module (1201).

[0231] In addition, the lens module (1201) may be equipped with two or more lens holders (1221, 1223) to implement an improved autofocus or zoom function.

[0232] Two or more lens holders (1221, 1223) can each move in the direction of the optical axis (Z-axis) and can be individually controlled.

[0233] If the camera module (1001) is equipped with two or more lens holders (1221, 1223), one of them can be used for automatic focus adjustment, and the remaining or all lens holders can be used for implementing a zoom function, thereby enabling the implementation of an improved automatic focus adjustment or zoom function.

[0234] Referring to FIG. 26, a camera module (1002) according to another embodiment of the present invention may include a reflection module (1100) and a lens module (1202).

[0235] In addition, the lens module (1202) may be equipped with three or more lens holders (1231, 1233, 1235) to implement an improved autofocus or zoom function.

[0236] Any one of the three or more lens holders (1231, 1233, 1235), in particular, the lens holder (1231) closest to the reflection module (1100), has a fixed position, and the remaining two or more lens holders (1233, 1235) can each move in the direction of the optical axis (Z-axis) and can be individually controlled.

[0237] Some of the lenses aligned in the optical axis direction of the camera module (1002) may be fixed (1231), and two or more remaining lens holders (1221, 1223) may be provided to be movable in the optical axis direction.

[0238] Further enhanced optical effects can be achieved by additionally providing some of the multiple lenses as fixed lenses. Additionally, since one of the movable lens holders can be used for autofocus adjustment and the remaining or all lens holders can be used for implementing a zoom function, further enhanced autofocus adjustment or zoom function can be achieved.

[0240] Through these embodiments, a camera module according to one embodiment of the present invention and a portable electronic device including the same can implement functions such as autofocus adjustment, zoom, shake correction, PIP, and tracking, while having a simple structure and being very easy to operate.

[0241] Although the structure and features of the present invention have been described above based on embodiments according to the present invention, the present invention is not limited thereto. It is obvious to those skilled in the art that various changes or modifications can be made within the spirit and scope of the present invention, and therefore, it is noted that such changes or modifications fall within the scope of the present invention.
