Abstract
Description
[Technical Field]
[0001] The present invention relates to a camera module. [Background technology]
[0002] Ultra-compact, low-power camera modules have been the subject of active research, as it is difficult to apply the voice coil motor (VCM) technology used in existing general camera modules.
[0003] In the case of a camera module mounted on a small electronic product such as a smartphone, the camera module is frequently subjected to impacts during use, and the camera module may be subject to slight shaking due to the user's hand shaking while taking a picture. In consideration of these issues, technology has been developed in recent years to add an anti-shake device to the camera module. Summary of the Invention [Problem to be solved by the invention]
[0004] The technical problem that the present invention aims to solve is to provide a miniaturized camera module. [Means for solving the problem]
[0005] In order to solve the above technical problems, a camera module according to an embodiment of the present invention includes a substrate, an image sensor disposed on the substrate, a plate disposed on the substrate, a base disposed on the plate, a lens barrel disposed on the base, a filter disposed on the plate, a first adhesive member disposed between the plate and the base, a second adhesive member disposed between the filter and the plate, and a third adhesive member disposed on an edge of the filter, wherein the third adhesive member is disposed to enclose an upper surface and an outer surface of the edge of the filter.
[0006] The third adhesive member can overlap the filter and the second adhesive member in the optical axis direction.
[0007] The third adhesive member may be disposed so as to enclose the outer surface of the second adhesive member, and the filter may be disposed between the second adhesive member and the third adhesive member.
[0008] The second adhesive member may have a smaller shrinkage rate than the third adhesive member.
[0009] The filter may include a hole, and a hole adhesive member may be disposed in the hole of the filter.
[0010] The plate may include an opening through which the image sensor passes, a first region in which the first adhesive member is disposed, and a second region in which the second adhesive member is disposed, and the first region and the second region may be spaced apart from each other.
[0011] The plate may include a third region connecting the first region and the second region, and the opening may be larger than the image sensor.
[0012] The first region of the plate may be formed to correspond to a lower surface of the base, and the second region of the plate may be formed to correspond to an edge of the filter.
[0013] The base may include an opening through which the lens barrel passes and a housing portion for housing the filter therein, and the filter may be spaced apart within the housing portion of the base.
[0014] In order to solve the above technical problems, a camera module according to an embodiment of the present invention includes a substrate, an image sensor disposed on the substrate, a plate disposed on the substrate, a base disposed on the plate, a housing disposed on the base, and a lens driving device including a bobbin disposed on the housing and movable in the optical axis direction, a lens barrel disposed in the bobbin, and a filter disposed on the plate, wherein the plate includes a first region corresponding to the underside of the base and a second region corresponding to the edge of the filter, and the filter is fixed to the plate with two adhesive members having different shrinkage rates.
[0015] The two adhesive members with different shrinkage rates may include a second adhesive member disposed between the filter and the plate and a third adhesive member disposed on the edge of the filter, and the shrinkage rate of the second adhesive member may be smaller than the shrinkage rate of the third adhesive member.
[0016] The second adhesive member, the third adhesive member, and the filter may be overlapped in the optical axis direction.
[0017] The filter may include a hole that does not overlap with the lens barrel in the optical axis direction, and a hole adhesive member may be disposed in the hole of the filter. [Effects of the Invention]
[0018] According to this embodiment, the distance between the image sensor and the lens barrel can be reduced through the moldless structure, so that a high CRA image sensor can be applied and the overall size of the camera module can be reduced.
[0019] Furthermore, by fixing the filter using two types of adhesive with different shrinkage rates, it is possible to prevent the filter from warping and breaking.
[0020] In addition, gases generated during the adhesive curing process can be released through the holes in the filter.
[0021] Furthermore, by providing a reinforcing member on the substrate, it is possible to prevent the substrate from warping even if an impact occurs due to the driving of the lens barrel.
[0022] In addition, by arranging a damper member in the area where the lens barrel comes into contact when it moves, the impact is absorbed, preventing damage to the filter, preventing damage to the lens, and preventing a decrease in resolution.
[0023] In addition, by applying a cross air vent design to the damper member, it is possible to prevent the lens and lens barrel from sticking to the damper member, which is made of silicone, and to make it easier to attach and detach. [Brief explanation of the drawings]

[0083] For example, the second coil 230 may include a circuit member 231 disposed on the circuit board 250 and a plurality of coil units 230-1 to 230-4 formed on the circuit member 231. Here, the circuit member 231 may be expressed as a "board," a "circuit board," a "coil board," or the like. In other embodiments, the second coil 230 may omit the circuit member 231 and include the coil units 230-1 to 230-4. The second coil 230 may be electrically connected to the circuit board 250 and may receive power or a drive signal from the circuit board 250.
[0084] Interaction between the magnets 130-1A to 130-4A and the second coils 230-1 to 230-4 to which the drive signals are provided allows the housing 140A to move in a second and / or third direction, for example, the X-axis and / or Y-axis directions, thereby enabling image stabilization.
[0085] The circuit board 250 is disposed on the upper surface of the base 210A and may include openings corresponding to the openings in the bobbin 120A, the openings in the housing 140A, and / or the openings 201A in the base 210. The openings in the circuit board 250 may be through-holes or hollows.
[0086] The circuit board 250 is disposed on the upper surface of the base 210A and may include a main body having an opening, and at least one terminal surface 253 bent from the main body to the outer surface of the base 210A. A plurality of terminals 251 for receiving an electrical signal from the outside or transmitting an electrical signal to the outside may be formed on the terminal surface 253 of the circuit board 250. The plurality of terminals 251 of the circuit board 250 may be electrically connected to at least one of the first coil 120, the first position sensor 170, the circuit board 190, the second position sensor 240, and the second coil 230.
[0087] The base 210A may include an opening 201A. The description of the base 210 in the embodiment of FIG. 3A may also be applied to FIG. 3B. In another embodiment, the base 210A and the housing 140A may be integrally formed, and such a configuration may be defined as the "base" or the "housing." The corners of the base 210A may be formed with escape portions 212 in the form of grooves, slots, or holes to avoid spatial interference with the support member 220.
[0088] The lens driving device 100A may further include a second position sensor 240 electrically connected to the circuit board 250. The second position sensor 240 may include two sensors 240a and 240b and may be electrically connected to the circuit board 250. Each of the two sensors 240a and 240b may be implemented as a position detection sensor alone, such as a Hall sensor, or may be implemented in the form of a driver including a Hall sensor. The base 210A may have a groove 215 for accommodating the sensors 240a and 240b.
[0089] Each of the sensors 240a and 240b senses the strength of the magnetic field of the magnets 130-1A to 130-4A as the housing 140 moves in a direction perpendicular to the optical axis, and outputs an output signal according to the sensed result. The displacement of the housing 140A in a direction perpendicular to the optical axis can be sensed using the output signals of the sensors 240a and 240b, and the controllers 830 and 780 can perform OIS feedback image stabilization using the output signals of the sensors 240a and 240b.
[0090] The lens driving device 100b shown in FIG. 3c may be a ball-type lens driving device.
[0091] 3c, the lens driving device 100b may include a housing 1400, a bobbin 1230 disposed within the housing 1400 and coupled to the lens module 400, a coil 1320 disposed in the housing 1400, a magnet 1310 disposed in the bobbin 1230, a ball 1600 disposed between the housing 1400 and the bobbin 1230, and a yoke 1340 disposed in the housing 1400. The ball 1600 may also be expressed as a "ball member" or a "ball bearing."
[0092] The lens driving device 100b may include a cover member 1100 coupled to the housing 1400 so as to enclose the outer surface of the housing 1400. The lens driving device 100b may include a position sensor 1350 disposed on the housing 1400. The lens driving device 100b may also include a circuit board 1330 disposed on the housing 1400, and the position sensor 1350 may be mounted on the circuit board 1330 and electrically connected to the circuit board 1330. The description of the position sensor in Figures 3a and 3b can also be applied to the position sensor 1350 in Figure 3c.
[0093] The bobbin 1230 may have an opening for coupling with the lens module, and the opening of the bobbin 1230 may be in the form of a through-hole that penetrates the bobbin in the optical axis direction. The magnet 1310 may be disposed on the outer surface of the bobbin 1230. A groove in which the magnet 1310 is disposed may be formed on the outer surface of the bobbin 1230.
[0094] The coil 1320 may be disposed on one side 1420 of the housing 1400, facing the magnet 1310. For example, a groove may be formed on one side of the housing 1400 for the magnet 1310 to be disposed therein. In other embodiments, the magnet may be disposed on the housing, and the coil may be disposed on a bobbin.
[0095] The housing 1400 may have an opening 1401 corresponding to the lens module 400, and the opening 1401 of the housing 140 may be in the form of a through-hole that penetrates the housing 1400 in the optical axis direction.
[0096] The coil 1320 can be electrically connected to a circuit board 1330 .
[0097] The ball 1600 can support the bobbin 1230 to move relative to the housing 1400. At least a portion of the ball 1600 can contact at least a portion of the housing 1400 and at least a portion of the bobbin 1230, thereby reducing friction between the housing 1400 and the bobbin 1230.
[0098] The yoke 1340 may be disposed on one side of the housing 1400 and may face the magnet 1310 in a direction perpendicular to the optical axis. For example, the yoke 1340 may be disposed outside the circuit board 1330, and the coil 1320 may be disposed between the yoke 1340 and the magnet 1310.
[0099] The yoke 1340 may be made of a material, such as a magnet or metal, that can generate an attractive force between it and the magnet 1310, thereby allowing an attractive force to act between the yoke 1340 and the magnet 1310 in a direction perpendicular to the optical axis direction. This attractive force allows the ball 1600 to maintain contact with the bobbin 1230 and the housing 1400.
[0100] The housing 1400 may be formed with a first receiving groove 1410 for receiving at least a portion of the ball 1600 or for disposing at least a portion of the ball 1600. The bobbin 1230 may be formed with a second receiving groove 1231 for receiving at least another portion of the ball 1600 or for disposing at least another portion of the ball 1600.
[0101] The first receiving groove 1410 may be formed on the inner side or inner surface of at least one corner of the housing 1400, and the second receiving groove 1231 may be formed on the outer side or outer surface of at least one corner of the bobbin 1230. The first receiving groove 1410 and the second receiving groove 1231 may face each other or face each other, and the ball 1600 may be disposed between the first receiving groove 1410 and the second receiving groove 1231 and may contact each of the first receiving groove 1410 and the second receiving groove 1231. The number of balls 1600 disposed between the first receiving groove 1410 and the second receiving groove 1231 may be one or more.
[0102] In FIG. 3c, a first receiving groove may be formed at each of two corners of the housing 1400 that face each other or are located on opposite sides, and a second receiving groove may be formed at each of two corners of the bobbin 1230 that correspond to the two corners of the housing 140.
[0103] In another embodiment, a first receiving groove may be formed at each of the four corners of the housing 1400, and a second receiving groove may be formed at each of the four corners of the bobbin 1230 corresponding to the four corners of the housing 140.
[0104] In another embodiment, a first receiving groove may be formed in each of two corners of the housing 1400 adjacent to the side 1420 of the housing 1400 where the coil 1320 and / or the circuit board 1330 are disposed.
[0105] Also, second receiving grooves may be formed at two corners of the bobbin 1230 corresponding to the two corners of the two adjacent housings 1400 and the side 1420 of the housing 1400 .
[0106] In another embodiment, a first receiving groove may be formed in each of two corners adjacent to a side portion located opposite the side portion 1420 of the housing 1400. A second receiving groove may be formed in each of two corners of the bobbin 1230 corresponding to the two corners adjacent to the side portion located opposite the side portion 1420 of the housing 1400.
[0107] As shown in Figure 3c, the housing 1400 can be realized as a single body, but is not limited to this. In another embodiment, the housing 1400 can include a housing and a base coupled to the housing, as shown in Figures 3a and 3b. In this case, the base can have an opening that is the same as or similar to the opening 1401 of the housing 1400.
[0108] For the sake of convenience, the following description will be given taking the base 210 of the lens driving device 100 as an example, but is not limited thereto. The following description can also be applied or analogously applied to the base 210A of the lens driving device 100A and the housing 1400 of the lens driving device 100b.
[0109] FIG. 3d may be a lens driving device 100C which is a modified embodiment of FIG. 3c.
[0110] In FIG. 3 d , the balls 1600 can be positioned between the two corners adjacent to the side 1420 of the housing 1400 on which the coil 1320 and / or circuit board 1330 are disposed and the corresponding outer surface of the bobbin 1230 .
[0111] For example, in FIG. 3d, a first accommodating groove 1410 can be formed in each of two corners of the housing 1400 adjacent to a side 1420 of the housing 1400 on which the coil 1320 and / or circuit board 1330 are arranged, and a second accommodating groove 1231 can be formed in corners of the bobbin 1230 corresponding to the two corners of the housing 1400.
[0112] The magnet 1310A can be disposed between the balls 1600 accommodated in the second accommodation grooves 1231 formed at the two corners of the bobbin 1230. For example, the magnet 1310A can be disposed between the two second accommodation grooves 1231 formed at the two corners of the bobbin 1230.
[0113] Figure 4a is a cross-sectional view of the area where an image sensor and filter are arranged according to this embodiment, Figure 4b is a cross-sectional view of the area where an image sensor and filter are arranged according to another embodiment of the present invention, Figure 5 is a diagram for explaining the arrangement of the filter and lens barrel in this embodiment, Figure 6 is a diagram showing a plate according to another embodiment of the present invention, and Figure 7 is a diagram showing a plate according to yet another embodiment of the present invention.
[0114] According to the embodiment of the present invention shown in FIG. 4a, the filter 610 may be disposed on the substrate 811. The second adhesive member 520 may be disposed between the filter 610 and the substrate 811. The second adhesive member 520 may fix the filter 610 on the substrate 811. The second adhesive member 520 may be disposed on the edge of the opening of the substrate 811. The second adhesive member 520 may be disposed corresponding to the edge of the filter 610. The second adhesive member 520 may be disposed on the lower surface 610b of the filter 610.
[0115] The filter 610 may be disposed on the second adhesive member 520, and the third adhesive member 530 may be disposed on the edge of the filter 610. The third adhesive member 530 may be disposed on the edge of the filter 610. The third adhesive member 530 may be disposed so as to surround the upper surface and outer surface of the edge of the filter 610. The third adhesive member 530 may be disposed on two opposite sides of the edge of the filter 610. The third adhesive member 530 may be disposed on four sides, which are the edge of the filter 610. The third adhesive member 530 may be disposed so as to surround the outer surface of the second adhesive member 520. The second adhesive member 520 and the third adhesive member 530 may be disposed to form a terminal.
[0116] The filter 610 may include an upper surface 610A, a lower surface 610b disposed opposite the upper surface 610A, and a side surface 610C connecting the upper surface 610A and the lower surface 610b. The upper surface 610A, the lower surface 610b, and the side surface 610C of the filter 610 may be in contact with an adhesive member. A portion of the upper surface 610A, a portion of the lower surface 610b, and a portion of the side surface 610C of the filter 610 may be in contact with an adhesive member. The lower surface 610b of the filter 610 may be in contact with the second adhesive member 520. The upper surface 610A of the filter 610 may be in contact with the third adhesive member 530. The side surface 610C of the filter 610 may be in contact with at least one of the second adhesive member 520 and the third adhesive member 530. The third adhesive member 530 can contact the upper surface 610A and the side surface 610C of the filter 610 and the upper surface and the side surface of the second adhesive member 520.
[0117] The second adhesive member 520 and the third adhesive member 530 may be UV-curable epoxy. The second adhesive member 520 and the third adhesive member 530 may have different shrinkage rates. The shrinkage rate of the second adhesive member 520 may be smaller than that of the third adhesive member 530. For example, the shrinkage rate of the second adhesive member 520 may be approximately 2% to 3%, and the shrinkage rate of the third adhesive member 530 may be 5% to 10% or more.
[0118] To secure the filter 610 to the substrate 811, the second adhesive member 520 is first applied to the substrate 811, and then the filter 610 is placed thereon. Then, the third adhesive member 530 is secondarily applied to the edge of the filter 610 and cured. The third adhesive member 530 has a higher shrinkage rate than the second adhesive member 520, so the third adhesive member 530 can apply tension (F) to the filter 610. As the third adhesive member 530 cures, shrinkage occurs, generating tension (F) that pulls the filter 610, minimizing the occurrence of waves in the filter 610. The second adhesive member 520 supports the filter 610, and the third adhesive member 530 generates tension in the filter 610 to prevent warping. The second adhesive member 520 and the third adhesive member 530 can secure the filter 610 in two stages.
[0119] A portion of the third adhesive member 530 disposed on the filter 610 may overlap with the lens barrel in the optical axis direction. A portion of the third adhesive member 530 may face the lower surface of the lens barrel. To prevent the lens barrel and the filter 610 from coming into contact when the lens barrel moves in the optical axis direction, the third adhesive member 530 may be disposed higher than the filter 610. When the lens barrel moves in the optical axis direction, the lens barrel may come into contact with the third adhesive member 530 before the filter 610.
[0120] 4b, the plate 310 may be disposed on the upper surface of the substrate 811. The base 210 may be disposed on the upper surface of the plate 310. The plate 310 may be disposed inside the base 210. A first adhesive member 510 may be disposed between the plate 310 and the base 210. The first adhesive member 510 may fix the base 210 onto the plate 310. The first adhesive member 510 may be applied to the plate 310 in correspondence with the lower surface of the base 210.
[0121] The plate 310 may include an opening through which the image sensor 810 passes. The opening of the plate 310 may be larger than the image sensor 810. The plate 310 may include an opening and may be formed to a size corresponding to the substrate 811. The plate 310 may be formed of a reinforcing member. The plate 310 may be formed of a material that has high resistance to external forces. For example, the plate 310 may be formed of a metal frame made of metal (e.g., stainless steel, aluminum, copper, etc.).
[0122] The filter 610 according to the present embodiment, which will be described below, is disposed by adhesive without any additional support structure, which reduces the area supporting the filter 610 and may make it vulnerable to impact. As image sensors with increased CRA (Chief Ray Angle) are adopted, the FBL length of the lens tends to become shorter. This can cause warping of the substrate due to impact caused by movement of the optical axis of the lens barrel or movement of the camera module, and the warping of the substrate can cause the filter to warp more significantly. Therefore, it is necessary to minimize the occurrence of warping of the substrate, which can cause contact between the filter and the image sensor. According to the present embodiment, the occurrence of warping of the substrate 811 can be minimized by disposing a plate 310, which is a reinforcing member, on the substrate 811.
[0123] 6 of another embodiment may include an opening through which the image sensor 810 passes, a first region 311 in which the first adhesive member 510 is disposed, and a second region 312 in which the second adhesive member 520 is disposed. The base 210 may be disposed on the first region 311. The first region 311 may be formed corresponding to an edge of the substrate 811. The first region 311 may be formed corresponding to a lower surface of the base 210. The filter 610 may be disposed on the second region 312. The second region 312 may be formed corresponding to an edge of the opening. The second region 312 may be formed corresponding to an edge of the opening in which the image sensor 810 is disposed.
[0124] The first region 311 and the second region 312 may be formed as a single region connected to each other. The first region 311 and the second region 312 may be formed separately. When the first region 311 and the second region 312 are formed separately, the plate 310 may have a hole between the first region 311 and the second region 312 in addition to the opening. By forming a hole in the plate 310, it is possible to minimize warping of the substrate and reduce the weight of the entire camera module. When the first region 311 and the second region 312 are separated, an impact occurring in each region may not affect each other.
[0125] 7 of another embodiment may include an opening through which the image sensor 810 passes, a first region 311 in which the first adhesive member 510 is disposed, a second region 312 in which the second adhesive member 520 is disposed, and a third region 313 connecting the first region 311 and the second region 312. The shapes of the first region 311, the second region 312, and the third region 313 may be modified in various ways. When the third region 313 connecting the first region 311 and the second region 312 is included, an impact generated in each region is transmitted to and buffered by the other regions, thereby reducing the amount of impact in each region.
[0126] The bases 210 and 210A of the lens driving device 100 shown in FIG. 3a and the lens driving device 100A shown in FIG. 3b may be disposed on a substrate 811. In this case, the filter 610 may be fixed to the substrate 811 with an adhesive member. The filter 610 may be fixed to the plate 310 with an adhesive member. The filter 610 may be disposed within the bases 210 and 210A. A structure in which the filter 610 is fixed only with an adhesive member without any additional support structure may be referred to as a moldless structure. The housings 1400 of the lens driving device 100b shown in FIG. 3c and the lens driving device 100C shown in FIG. 3d may be disposed on the substrate 811. In this case, the filter 610 may be fixed to the substrate 811 with an adhesive member. Although a base is not shown in FIGS. 3c and 3d, a base may be further disposed between the housing 1400 and the substrate 811. In this case, the filter 610 may be disposed inside the opening of the base.
[0127] The base 210, 210A may include a receiving portion that receives the filter 610 therein. The filter 610 may be spaced apart within the receiving portion of the base 210, 210A. The receiving portion of the base 210, 210A may refer to a space in which the filter 610 is disposed. The inner surface of the base 210, 210A may face the outer surface of the filter 610.
[0128] The bases 210 and 210A may include an opening through which the lens barrel passes. The lens barrel can pass through the opening of the bases 210 and 210A by moving in the optical axis direction. When the lens barrel moves closest to the image sensor 810, it can pass through the opening of the bases 210 and 210A. When the lens barrel moves farthest from the image sensor 810, it may not pass through the opening of the bases 210 and 210A.
[0129] According to another embodiment of the present invention shown in Fig. 4b, a filter 610 may be disposed on the plate 310. A second adhesive member 520 may be disposed between the filter 610 and the plate 310. The second adhesive member 520 may fix the filter 610 on the plate 310. The second adhesive member 520 may be disposed on the edge of the opening of the plate 310. The second adhesive member 520 may be disposed corresponding to the edge of the filter 610. The second adhesive member 520 may be disposed on the lower surface of the filter 610.
[0130] The filter 610 may be disposed on the second adhesive member 520, and the third adhesive member 530 may be disposed on the edge of the filter 610. The third adhesive member 530 may be disposed on the edge of the filter 610. The third adhesive member 530 may be disposed so as to surround the upper surface and outer surface of the edge of the filter 610. The third adhesive member 530 may be disposed on two opposite sides of the edge of the filter 610. The third adhesive member 530 may be disposed on four sides, which are the edge of the filter 610. The third adhesive member 530 may be disposed so as to surround the outer surface of the second adhesive member 520. The second adhesive member 520 and the third adhesive member 530 may be disposed to form a terminal.
[0131] The filter 610 may include an upper surface 610A, a lower surface 610b disposed opposite the upper surface 610A, and a side surface connecting the upper surface 610A and the lower surface 610b. The upper surface 610A, the lower surface 610b, and the side surface 610C of the filter 610 may be in contact with an adhesive member. A portion of the upper surface 610A, a portion of the lower surface 610b, and a portion of the side surface 610C of the filter 610 may be in contact with an adhesive member. The lower surface 610b of the filter 610 may be in contact with the second adhesive member 520. The upper surface 610A of the filter 610 may be in contact with the third adhesive member 530. The side surface 610C of the filter 610 may be in contact with at least one of the second adhesive member 520 and the third adhesive member 530. The third adhesive member 530 may be in contact with the upper surface 610A and the side surface 610C of the filter 610 and the side surface of the second adhesive member 520.
[0132] The second adhesive member 520 and the third adhesive member 530 may be UV-curable epoxy. The second adhesive member 520 and the third adhesive member 530 may have different shrinkage rates. The shrinkage rate of the second adhesive member 520 may be smaller than the shrinkage rate of the third adhesive member 530. For example, the shrinkage rate of the second adhesive member 520 may be approximately 2% to 3%, and the shrinkage rate of the third adhesive member 530 may be 5% to 10% or more.
[0133] To secure the filter 610 to the plate 310, the second adhesive member 520 is first applied to the plate 310, and then the filter 610 is placed thereon. Then, the third adhesive member 530 is secondarily applied to the edge of the filter 610 and cured. Because the third adhesive member 530 has a higher shrinkage rate than the second adhesive member 520, the third adhesive member 530 can apply tension (F) to the filter 610. As the third adhesive member 530 cures, shrinkage occurs, generating tension (F) that pulls the filter 610, minimizing the occurrence of waves in the filter 610. The second adhesive member 520 supports the filter 610, and the third adhesive member 530 generates tension in the filter 610 to prevent warping. The second adhesive member 520 and the third adhesive member 530 can secure the filter 610 in two stages.
[0134] A portion of the third adhesive member 530 disposed on the filter 610 may overlap with the lens barrel in the optical axis direction. A portion of the third adhesive member 530 may face the lower surface of the lens barrel. To prevent the lens barrel and the filter 610 from coming into contact when the lens barrel moves in the optical axis direction, the third adhesive member 530 may be disposed higher than the filter 610. When the lens barrel moves in the optical axis direction, the lens barrel may come into contact with the third adhesive member 530 before the filter 610.
[0135] A damper member (not shown) may be disposed in an area of the third adhesive member 530 facing the lower surface of the lens barrel. The damper member may be formed by applying epoxy after the third adhesive member 530 has hardened. The damper member may be inserted into the third adhesive member 530 and hardened together before the third adhesive member 530 is applied and hardened. In this case, the damper member may be made of a silicone material.
[0136] When the lens barrel moves adjacent to the image sensor 810, the damper member comes into contact with the lower surface of the lens barrel to absorb shock and cushion the impact. The damper member can be arranged to overlap with the lens barrel in the optical axis direction. The damper member can be arranged to overlap with the lower surface of the lens barrel in the optical axis direction. The damper member can be arranged to come into contact with the lower surface of the lens barrel as the lens barrel moves in the optical axis direction within the opening of the base 210, 210A.
[0137] A groove may be formed on the upper surface of the damper member. The groove of the damper member 315 may be formed in a cross shape on the upper surface. The groove of the damper member may facilitate attachment and detachment when it comes into contact with the lower surface of the lens barrel. The groove of the damper member may serve to partition the upper surface of the damper member for facilitating attachment and detachment while ensuring a contact area between the damper member and the lower surface of the lens barrel. The groove of the damper member may be formed in various shapes, such as a circle or a star shape recessed in the center of the upper surface.
