[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of priority from Korean Patent Application No. 10-2023-0152206 filed on November 6, 2023, in the Korean Intellectual Property Office, and Korean Patent Application No. 10-2024-0113046 filed on August 22, 2024, in the Korean Intellectual Property Office, the disclosures of which are incorporated herein in their entirety by reference for all purposes. Technical Field

[0003] The following description relates to a camera module and a portable electronic device including the camera module. Background Art

[0004] The camera module is implemented in portable electronic devices such as, but not limited to, smart phones, tablet personal computers (PCs), and laptop computers, and may have an auto focus (AF) function, a hand shake correction function, a zoom function, and the like.

[0005] In order to implement such a function, the camera module may be provided with an actuator that moves a lens and a reflective member such as a prism.

[0006] The lens and the reflective member may collide with the surrounding injection molded products while moving in the internal space of the housing based on the driving force of the actuator. Specifically, when the reflective member with a relatively large load collides with the injection molded product, there may be a problem that the impact force and the size of the collision sound are inevitably increased.

[0007] The above information is presented as background information only to assist with understanding the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with respect to the present disclosure. Summary of the invention

[0051] The camera module 1000 according to one or more embodiments may include a plurality of lenses, and the optical axes (Z-axis) of the plurality of lenses may face a direction perpendicular to the thickness direction (Y-axis direction, for example, the direction from the front surface to the rear surface of the portable electronic device 1 or the opposite direction thereof) of the portable electronic device 1.

[0052] Figure 2 A perspective view showing an exemplary camera module according to one or more embodiments, and Figure 3 An internal perspective view of a camera module according to one or more embodiments is shown.

[0053] Reference Figure 2 and Figure 3 , a camera module 1000 according to one or more embodiments may include a housing 1010 , and a reflection module 1100 , a lens module 1200 , and an image sensor module 1300 disposed in the housing 1010 .

[0054] The reflection module 1100 may change the moving direction of light. The reflection module 1100 may include a reflection member 1110 (see Figure 4 ). In an example, the reflective member 1110 may be provided as a prism, a reflective mirror, or the like.

[0055] The direction of light incident through the opening 1031 of the cover 1030 disposed to cover the upper portion of the housing 1010 may be changed into a direction toward the lens module 1200 by the reflection module 1100 .

[0056] The path of light incident in the thickness direction (Y-axis direction) of the camera module 1000 may be changed so that the light substantially coincides with the optical axis (Z-axis) in the reflection module 1100 and may be incident on the lens module 1200 .

[0057] The lens module 1200 may include a plurality of lenses arranged in an optical axis direction (Z-axis direction).

[0058] Reference Figure 4 , the image sensor module 1300 may include an image sensor 1310 and a sensor substrate 1320 , the image sensor 1310 being configured to convert light passing through the lens module 1200 into an electrical signal, and the image sensor 1310 being mounted on the sensor substrate 1320 .

[0059] In addition, the image sensor module 1300 may include an optical filter 1330 that filters light incident on the image sensor 1310. In an example, the optical filter 1330 may be an infrared blocking filter.

[0060] Reference Figure 3 and Figure 4 , the reflection module 1100 may be disposed in front of the lens module 1200 in the internal space of the housing 1010 , and the image sensor module 1300 may be disposed behind the lens module 1200 .

[0061] In addition, the outer surface of the housing 1010 may be provided with a first driver 1140 for driving the reflection module 1100, a second driver 1240 for driving the lens module 1200, and various substrates 1070 and 1320 such as a main substrate 1070 and a sensor substrate 1320 for supplying power to the image sensor 1310 or sending / receiving control signals to / from the image sensor 1310.

[0062] Figure 4 An exploded perspective view of an exemplary camera module is shown.

[0063] The camera module 1000 according to one or more embodiments may implement an auto focus (AF) function when the lens module 1200 moves in the optical axis direction (Z-axis direction).

[0064] The lens module 1200 may include a lens support 1210 on which a plurality of lenses are mounted. Figure 4 , shows an embodiment in which one lens holder 1210 is provided. However, this is only an example, and a plurality of lens holders may be provided. A plurality of lenses may be directly mounted on the lens holder 1210, or may be mounted on the lens holder 1210 through a lens barrel.

[0065] The auto focus (AF) function of the camera module 1000 can be realized by the movement of the lens holder 1210 provided with a plurality of lenses in the optical axis direction (Z axis direction). When a plurality of lens holders are provided, the auto focus (AF) function and the zoom function can be realized when one or more lens holders move in the optical axis direction (Z axis direction). The plurality of lens holders can be provided to be independently movable.

[0066] The lens holder 1210 may be moved in the optical axis direction (Z-axis direction) by the second driver 1240 .

[0067] Reference Figure 4 , the second driver 1240 may include a plurality of magnets 1241 and a plurality of coils 1243 arranged to face the plurality of magnets 1241. The magnet 1241 and the coil 1243 do not necessarily have to be provided in plural, but one or more magnets and coils may be provided.

[0068] Each magnet 1241 may be magnetized to have an N pole and an S pole in sequence (or vice versa) in the optical axis direction (Z-axis direction), and may correspond one-to-one to the coil 1243 .

[0069] When power is supplied to the plurality of coils 1243 , the lens holder 1210 may move in the optical axis direction (Z-axis direction) based on electromagnetic influence between the plurality of magnets 1241 and the plurality of coils 1243 .

[0070] In an exemplary embodiment, a plurality of magnets 1241 may be disposed on each of both side surfaces of the lens holder 1210 , and a plurality of coils 1243 may be disposed on each of both side surfaces of the housing 1010 so as to face the plurality of magnets 1241 , respectively.

[0071] In addition, in an example, the plurality of coils 1243 may be mounted on the main substrate 1070, and the main substrate 1070 may be attached to the outer surface of the housing 1010. The housing 1010 may include through holes 1010-3 and 1010-4 that expose the plurality of coils 1243 to the inside of the housing 1010, so that the plurality of magnets 1241 and the plurality of coils 1243 directly face each other.

[0072] The second driver 1240 may include a position detection sensor 1245 that senses the position of the lens holder 1210. In an example, the position detection sensor 1245 may be a Hall sensor.

[0073] In an example, the position detection sensor 1245 may be disposed inside or outside the coil 1243 , and may be mounted on the main substrate 1070 together with the coil 1243 .

[0074] In an example, the lens holder 1210 may smoothly move in the optical axis direction (Z-axis direction) on the bottom surface of the housing 1010 by the plurality of ball members 1250. As an example only, the plurality of ball members 1250 may be provided in three or more.

[0075] In an example, guide grooves 1215 and 1015 extending in the optical axis direction (Z-axis direction) may be provided on the bottom surfaces of the lens holder 1210 and the housing 1010. A plurality of ball members 1250 may be inserted between the guide grooves 1215 and 1015 so as to guide the movement of the lens holder 1210 while rolling along the guide grooves 1215 and 1015 in the optical axis direction (Z-axis direction).

[0076] In order for the plurality of ball members 1250 to continuously contact the guide grooves 1215 and 1015 during the movement of the lens holder 1210 , the camera module 1000 may include a pulling device that pulls the lens holder 1210 toward the bottom surface of the housing 1010 .

[0077] The pulling device may be arranged to face each other on the lens holder 1210 and the housing 1010. For example, the pulling device may be provided with a magnetic member, and the pulling magnet 1216 may be placed in the lens holder 1210, and the pulling yoke 1016 may be provided in the housing 1010. The positions of the pulling magnet 1216 and the pulling yoke 1016 may be interchanged. The pulling magnet 1216 and the pulling yoke 1016 may generate attractive forces in opposite directions (Y-axis directions).

[0078] The movement of the lens holder 1210 in the optical axis direction (Z axis direction) may be a relative movement with respect to the housing 1010. Therefore, when the lens holder 1210 moves in the optical axis direction (Z axis direction), the gap between the lens holder 1210 and the mating housing 1010 may become closer.

[0079] The camera module 1000 may include a stopper 1040 configured to limit a moving distance of the lens holder 1210 to prevent a collision between the lens holder 1210 and the housing 1010 .

[0080] The stopper 1040 may be provided on the housing 1010 so as to face the lens holder 1210 in the optical axis direction (Z-axis direction). The lens holder 1210 may contact the stopper 1040 instead of the housing 1010.

[0081] Refer again Figure 4 , the camera module 1000 according to one or more embodiments may implement an optical image stabilization (OIS) function based on the rotation of the reflection module 1100 .

[0082] When capturing an image or a video, the image may be blurred or the video may be shaken due to hand shake of the user, etc., and the camera module 1000 can compensate for the hand shake of the user, etc. by rotating the reflection module 1100 in a direction to compensate for the shake.

[0083] The reflection module 1100 may include a rotating bracket 1120 on which the reflection member 1110 is mounted.

[0084] The rotating bracket 1120 may be rotatably accommodated in the housing 1010. For example, the rotating bracket 1120 may rotate about a first axis (X axis) and a second axis (Y axis) perpendicular to the optical axis (Z axis) while being accommodated in the housing 1010. An optical image stabilization (OIS) function of the camera module 1000 may be implemented by the rotation of the rotating bracket 1120.

[0085] The reflection module 1100 may include a rotation guide 1130 disposed between the rotation bracket 1120 and the housing 1010 .

[0086] In an exemplary embodiment, a first ball bearing 1151 may be disposed between the housing 1010 and the rotation guide 1130 , and a second ball bearing 1153 may be disposed between the rotation guide 1130 and the rotation bracket 1120 .

[0087] Figure 5 It is along Figure 2 A cross-sectional view of the camera module taken along line II', Figure 6 It is along Figure 2 A cross-sectional view of the camera module taken along line II-II'.

[0088] Reference Figure 5 , one surface of the rotation guide 1130 may be spaced apart from the inner side of the housing 1010, and the first ball bearing 1151 may be interposed therebetween. The first receiving groove 1133 and the second receiving groove 1013 may be provided on surfaces of the rotation guide 1130 and the housing 1010 facing each other. The first ball bearing 1151 may be inserted between the first receiving groove 1133 and the second receiving groove 1013. Some of the first receiving groove 1133 and the second receiving groove 1013 may be provided in a shape different from that of the other receiving grooves.

[0089] The first ball bearing 1151 may maintain a gap between the inner surface of the housing 1010 and the rotation guide 1130. In addition, the first ball bearing 1151 may be a first axis (X axis) which is a rotation axis of the rotation bracket 1120.

[0090] In an exemplary embodiment, the first ball bearing 1151 may include two ball members spaced apart in the first axis direction (X axis direction), and the first axis (X axis) may pass through the two ball members. The first ball bearing 1151 may operate as a rotation axis when rotating in situ while being inserted between the first receiving groove 1133 and the second receiving groove 1013.

[0091] Reference Figure 6 , the other surface of the rotating guide 1130 may be spaced apart from the rotating bracket 1120, and the second ball bearing 1153 may be interposed therebetween. The third receiving groove 1131 and the fourth receiving groove 1121 may be provided on surfaces of the rotating guide 1130 and the rotating bracket 1120 facing each other. The second ball bearing 1153 may be inserted between the third receiving groove 1131 and the fourth receiving groove 1121. Some of the third receiving groove 1131 and the fourth receiving groove 1121 may be provided in a shape different from that of the other receiving grooves.

[0092] The second ball support 1153 may maintain a gap between the rotating bracket 1120 and the rotating guide 1130. In addition, the second ball support 1153 may be a second axis (Y axis) which is another rotation axis of the rotating bracket 1120.

[0093] In an exemplary embodiment, the second ball bearing 1153 may include two ball members spaced apart from each other in the second axis direction (Y axis direction), and the second axis (Y axis) may pass through the two ball members. The second ball bearing 1153 may be used as a rotation axis when rotating in situ while being inserted between the third receiving groove 1131 and the fourth receiving groove 1121.

[0094] In an exemplary embodiment, the rotating bracket 1120 and the rotating guide 1130 may be supported on the inner surface of the housing 1010, and the first ball bearing 1151 and the second ball bearing 1153 are respectively located between the inner surface of the housing 1010 and the rotating guide 1130 and between the rotating bracket 1120 and the rotating guide 1130. Therefore, the camera module 1000 may include a pulling device that pulls the rotating bracket 1120 toward the inner surface of the housing 1010.

[0095] The traction device may be provided to face each other on the rotating bracket 1120 and the housing 1010. In an example, the traction device may be provided as a magnetic member, and the traction magnet 1127 may be provided on the rotating bracket 1120, and the traction yoke 1017 may be provided on the housing 1010. The positions of the traction magnet 1127 and the traction yoke 1017 may be interchanged.

[0096] The rotating guide 1130 disposed between the rotating bracket 1120 and the housing 1010 may include a through hole 1135, and the pulling magnet 1127 and the pulling yoke 1017 may face each other through the through hole 1135. The pulling magnet 1127 and the pulling yoke 1017 may generate an attractive force in a direction (Z-axis direction) in which the pulling magnet 1127 and the pulling yoke 1017 are opposite to each other. Based on the attractive force between the pulling magnet 1127 and the pulling yoke 1017, the first ball support 1151 and the second ball support 1153 may be in continuous contact with the first receiving groove 1133, the second receiving groove 1013, the third receiving groove 1131, and the fourth receiving groove 1121 in which the first ball support 1151 and the second ball support 1153 are disposed.

[0097] The rotating bracket 1120 provided with the reflective member 1110 may be rotated around the first axis (X axis) and the second axis (Y axis) by the first driver 1140. In an exemplary embodiment, when the rotating bracket 1120 rotates around the first axis (X axis), the rotating guide 1130 may also rotate together, and the rotation of the rotating bracket 1120 around the second axis (Y axis) may be a relative rotation with respect to the rotating guide 1130. However, when the positions of the first ball support 1151 and the second ball support 1153 are changed, the rotating guide 1130 may be rotated around the second axis (Y axis) together with the rotating bracket 1120, and the rotation of the rotating bracket 1120 around the first axis (X axis) may be a relative rotation with respect to the rotating guide 1130.

[0098] Reference Figure 4 , the first driver 1140 may include a plurality of magnets 1141a and 1141b and a plurality of coils 1143a and 1143b disposed to face the plurality of magnets 1141a and 1141b.

[0099] The plurality of magnets 1141 a and 1141 b may include a first driving magnet 1141 a that rotates the rotating bracket 1120 around a first axis (X axis) and a second driving magnet 1141 b that rotates the rotating bracket 1120 around a second axis (Y axis).

[0100] In an exemplary embodiment, two first drive magnets 1141a and two second drive magnets 1141b may be provided, respectively, and the two first drive magnets 1141a may be separated and mounted on the two side surfaces of the rotating bracket 1120, and the two second drive magnets 1141b may be separated and mounted on the two side surfaces of the rotating bracket 1120. That is, the first drive magnet 1141a and the second drive magnet 1141b may be provided on one side surface of the rotating bracket 1120. For example, the first drive magnet 1141a and the second drive magnet 1141b may be provided to be parallel in the optical axis direction (Z-axis direction). The two side surfaces of the rotating bracket 1120 may extend (hereinafter referred to as the extension portion 1120a) to the opposite side (e.g., -Z-axis direction) of the reflective member 1110. A portion of the second drive magnet 1141b may be provided in the extension portion 1120a.

[0101] The first driving magnet 1141a can be magnetized to have an N pole and an S pole in sequence along the first axis direction (X axis direction) (or vice versa), and the second driving magnet 1141b can be magnetized to have an N pole and an S pole in sequence along the second axis direction (Y axis direction) (or vice versa).

[0102] The plurality of coils 1143a and 1143b may include a first driving coil 1143a disposed to face the first driving magnet 1141a and a second driving coil 1143b disposed to face the second driving magnet 1141b. The first driving coil 1143a and the second driving coil 1143b may correspond one-to-one to the first driving magnet 1141a and the second driving magnet 1141b, respectively.

[0103] When power is supplied to the plurality of coils 1143a and 1143b, the rotating bracket 1120 may rotate about a first axis (X axis) and / or a second axis (Y axis) based on electromagnetic influences between the plurality of magnets 1141a and 1141b facing the plurality of coils 1143a and 1143b and the plurality of coils 1143a and 1143b.

[0104] The plurality of coils 1143a and 1143b may be mounted on the main substrate 1070, and the main substrate 1070 may be attached to the outer surface of the housing 1010. The housing 1010 may include through holes 1010-1 and 1010-2 configured to expose the plurality of coils 1143a and 1143b to the inside of the housing 1010 so that the plurality of magnets 1141a and 1141b and the plurality of coils 1143a and 1143b directly face each other.

[0105] The first driver 1140 may include a position sensing device that senses the position of the rotating bracket 1120. The position sensing device may include a sensing magnet 1144 and a position detection sensor 1145. In an example, the position detection sensor 1145 may be a Hall sensor.

[0106] Two sensing magnets 1144 may be provided and may be installed on both side surfaces of the rotating bracket 1120 together with the first and second driving magnets 1141a and 1141b, respectively. The sensing magnet 1144 may be spaced apart from the first driving magnet 1141a in the second axis direction (Y axis direction).

[0107] The sensing magnet 1144 may have a polarity opposite to that of a polarity region of the first driving magnet 1141a disposed adjacent to the sensing magnet 1144. For example, the sensing magnet 1144 may be disposed to have an N pole or an S pole.

[0108] The position detection sensor 1145 may be mounted on the main substrate 1070 together with the plurality of coils 1143a and 1143b.

[0110] Figure 7 A perspective view showing a rotating bracket according to one or more embodiments, and Figure 8 is shown with Figure 7 A view of a rotating bracket separating the multiple cushioning members.

[0111] Reference Figure 7 , the rotating bracket 1120 may be provided with a plurality of buffer members 1181 and 1183. The plurality of buffer members 1181 and 1183 may be provided to protrude from the rotating bracket 1120 toward the counterpart. In the example, since the plurality of buffer members 1181 and 1183 directly collide with the counterpart when the rotating bracket 1120 is rotated to the maximum position, direct collision between the rotating bracket 1120 and the counterpart may be prevented. In addition, since the plurality of buffer members 1181 and 1183 contact the counterpart, the rotation range of the rotating bracket 1120 may be limited.

[0112] The plurality of buffer members 1181 and 1183 may be formed of a soft material to mitigate impact or noise caused by collision. For example, the plurality of buffer members 1181 and 1183 may be formed of a liquid crystal polymer (LCP) material and may also include a shock absorbing material such as polyurethane, rubber, silicone or natural sponge.

[0113] In an exemplary embodiment, the plurality of buffer members 1181 and 1183 may be integrally provided with the rotating bracket 1120. For example, the plurality of buffer members 1181 and 1183 may be directly inserted into the rotating bracket 1120. That is, a separate manufacturing process for assembling the plurality of buffer members 1181 and 1183 into the rotating bracket 1120 may be omitted, and the rotating bracket 1120 itself may be provided in the form of including the plurality of buffer members 1181 and 1183.

[0114] In an exemplary embodiment, the plurality of buffer members 1181 and 1183 may be attached to the rotating bracket 1120 through the supporting frame 1129. For example, the supporting frame 1129 may be formed of a steel material member inserted into the rotating bracket 1120. The plurality of buffer members 1181 and 1183 may be provided in the rotating bracket 1120 in a state of being attached to the supporting frame 1129.

[0115] Fig. 9 is an exploded perspective view of a rotating bracket and a housing according to one or more embodiments, and Fig.10 is along Figure 2 A cross-sectional view of the camera module taken along line III-III'.

[0116] In an exemplary embodiment, the rotating bracket 1120 may include a first buffer member 1181 disposed on a surface of the rotating bracket 1120 facing the bottom surface of the housing 1010 (hereinafter referred to as the bottom surface of the rotating bracket 1120 ).

[0117] The first buffer member 1181 may be provided in plurality, and the plurality of first buffer members 1181 may be spaced apart from each other in the first axis direction (X-axis direction) on the bottom surface of the rotating bracket 1120 .

[0118] The first buffer member 1181 can be configured to protrude from the bottom surface of the rotating bracket 1120 toward the bottom surface of the shell 1010, so that when the rotating bracket 1120 rotates relative to the shell 1010 around the first axis (X axis), a collision generated in the second axis direction (Y axis direction) can be prevented.

[0119] The first buffer member 1181 may include a first protrusion 1181 a and a first damping hole 1181 b .

[0120] The first protrusion 1181a may be a portion that protrudes further toward the bottom surface of the housing 1010 than the surrounding area on the surface of the first buffer member 1181 opposite to the bottom surface of the housing 1010. Therefore, in a state where the rotating bracket 1120 is rotated to the maximum position, the first protrusion 1181a of the first buffer member 1181 may first contact the bottom surface of the housing 1010.

[0121] In an exemplary embodiment, the first protrusion 1181a may have a shape inclined in one direction. The first protrusion 1181a may have a shape inclined in a direction (Z-axis direction) in which the first buffer member 1181 is spaced apart from the first axis (X-axis).

[0122] In an example, the first protrusion 1181a may be provided in such a manner that the distance between the first protrusion 1181a and the bottom surface of the housing 1010 increases as the first protrusion 1181a approaches the first axis (X axis) and conversely decreases as the first protrusion 1181a extends away from the first axis (X axis). According to the above structure, since the gap between the first buffer member 1181 and the housing 1010 is narrowly formed in a portion where the rotation amount of the rotating bracket 1120 is relatively large, collision can be effectively prevented.

[0123] The first damping hole 1181b may be provided to pass through the first buffer member 1181. The first damping hole 1181b may be provided between a surface of the first buffer member 1181 facing the housing 1010 (e.g., a surface including the first protrusion 1181a) and the bottom surface of the rotating bracket 1120, thereby absorbing the impact transmitted from the first protrusion 1181a to the rotating bracket 1120. However, the first damping hole 1181b may be omitted.

[0124] When the rotating bracket 1120 is in an intermediate position, for example, when the bottom surface of the rotating bracket 1120 and the bottom surface of the shell 1010 are parallel to each other, the first buffer member 1181 can be spaced apart from the bottom surface of the shell 1010, and when the rotating bracket 1120 rotates around the first axis (X-axis), the gap between the first buffer member 1181 and the bottom surface of the shell 1010 can be reduced, so that the first buffer member 1181 can first contact the bottom surface of the shell 1010.

[0125] Fig.11 is an exploded perspective view of a rotating bracket and a rotating plate according to one or more embodiments, Fig.12 is a rear view of a rotating stand according to one or more embodiments, and Fig.13 is a plan view of a reflective module according to one or more embodiments.

[0126] In an exemplary embodiment, the rotating bracket 1120 may include a second buffer member 1183 disposed on a surface of the rotating bracket 1120 facing the rotating guide 1130 (hereinafter, one surface of the rotating bracket 1120 ).

[0127] The second buffer member 1183 may be provided in plurality, and the plurality of second buffer members 1183 may be spaced apart from each other in the first axis direction (X axis direction) on one surface of the rotating bracket 1120. Fig.11 , the plurality of second buffer members 1183 may be spaced apart from each other in the first axis direction (X axis direction) with the second axis (Y axis) interposed therebetween. In an exemplary embodiment, the second ball bearing 1153 may be interposed between the plurality of second buffer members 1183 spaced apart from each other.

[0128] The second buffer member 1183 can be configured to protrude toward the rotating guide 1130 on a surface of the rotating bracket 1120, and when the rotating bracket 1120 rotates around the second axis (Y axis) relative to the rotating guide 1130, it can prevent collision in the direction of the optical axis (or third axis) (Z axis direction).

[0129] Reference Fig.12 , the second buffer member 1183 may include second protrusions 1183a-1 and 1183a-2.

[0130] The second protrusions 1183a-1 and 1183a-2 may be portions that protrude further toward the rotating guide 1130 than the surrounding area on the surface of the second buffer member 1183 opposite to the rotating guide 1130. Therefore, when the rotating bracket 1120 rotates to the maximum position, the second protrusions 1183a-1 and 1183a-2 of the second buffer member 1183 may first contact the rotating guide 1130.

[0131] In an exemplary embodiment, the second protrusions 1183a-1 and 1183a-2 may have a shape inclined in one direction. The second protrusions 1183a-1 and 1183a-2 may have a shape inclined in a direction (X-axis direction) in which the second buffer member 1183 is spaced apart from the second axis (Y-axis).

[0132] In an example, the second protrusions 1183a-1 and 1183a-2 may be provided in such a manner that the distance between the second protrusions 1183a-1 and 1183a-2 and the rotating guide 1130 increases as the second protrusions 1183a-1 and 1183a-2 approach the second axis (Y axis), and conversely, the distance between the second protrusions 1183a-1 and 1183a-2 and the rotating guide 1130 decreases as the second protrusions 1183a-1 and 1183a-2 extend away from the second axis (Y axis). According to the above structure, since the gap between the second buffer member 1183 and the rotating guide 1130 can be narrowly formed in a portion where the rotation amount of the rotating bracket 1120 is relatively large, collision can be effectively prevented.

[0133] When the rotating bracket 1120 is in an intermediate position, for example, when a surface of the rotating bracket 1120 and a surface of the rotating guide 1130 opposite to the surface are parallel to each other, the second buffer member 1183 can be spaced apart from the rotating guide 1130, and when the rotating bracket 1120 rotates around the second axis (Y axis), the gap between the second buffer member 1183 and the rotating guide 1130 can be reduced so that the second buffer member 1183 can first contact the rotating guide 1130.

[0134] In addition, although omitted in the drawings, the second buffer member 1183 may further include a second through hole passing through the second buffer member 1183 .
