In another embodiment, the first coil is perpendicular to the optical axis. may overlap at least a portion of each of the second and third magnets 180, 185 in the direction do.

[0111] For example, the first coil 120 may be disposed in the seating groove 105 of the bobbin 110. The second magnet 180 is inserted or placed in the seating groove 180a of the bobbin 110. The third magnet 185 can be inserted or fixed into the seating groove 185a of the bobbin 110. It can be arranged.

In other embodiments , each of the second magnet 180 and the third magnet 185 disposed on the bobbin 110 either contacts the first coil 120 or overlaps a part of the first coil 120 in a direction perpendicular to the optical axis may be.

[0113] The first coil 120 can cover the outer surface of the bobbin 110 in a direction of rotation about the optical axis (OA). For example, the first coil 120 can be a closed curve wound around the outer surface of the bobbin 110 , for example, can have a ring shape.

[0114] The first coil 120 may be directly wound on the outer surface of the bobbin 110, but is not limited thereto. According to other embodiments, the first coil 120 can be wound on the bobbin 110 using a coil ring or can be provided by a coil block having a square ring shape.

[0116] When a drive signal (for example, drive current) is supplied to the first coil 120, an electromagnetic force can be formed by electromagnetic interaction with the first magnet 130, and the formed electromagnetic force can move the bobbin 110 in the direction of the optical axis (OA).

[0117] At the initial position of the AF movable part, the bobbin 110 can move in the upper direction or the lower direction, and this is called two-way driving of the AF movable part.

[0118] Or at the initial position of the AF movable part, the bobbin 110 can move in the upward direction, and this is the unidirectional driving of the AF movable part.

[0119] At the initial position of the AF movable part, in a direction perpendicular to the optical axis (OA) and parallel to the straight line passing through the optical axis, the first coil 120 can be arranged to correspond to or overlap with the first magnet 130 arranged in the housing 140.

Now, the third magnet 185 cancels out the magnetic field influence of the sensing magnet 180, and in terms of being for weight balancing with the sensing magnet 180, it may be expressed as a "balancing magnet".

[0125] The second magnet 180 can be arranged in the seating groove 180a of the bobbin 110 so as to face the first position sensor 170. For example, at the initial position of the bobbin 110, the second magnet 180 is perpendicular to the optical axis and parallel to the straight line passing through the optical axis, and overlaps with the first position sensor 170, but is not limited thereto. In other embodiments, at the initial position of the bobbin 110, the second magnet 180 and the first position sensor 170 in a direction perpendicular to the optical axis and parallel to the straight line passing through the optical axis may not overlap.

In other embodiments, a part of any one surface of the second magnet 180 facing the first position sensor 170 may not be exposed from the seating groove 180a.

[0127] For example, each of the second and third magnets 180, 185 can be an anodized magnet or a four - pole magnet including two N - poles and two S - poles.

[0128] Each of the second and third magnets 180, 185 can include a first magnet part 17a, a second magnet part 17b, and a partition wall 17c arranged between the first magnet part 17a and the second magnet part 17b.

[0131] The partition wall 17c separates or isolates the first magnet part 17a and the second magnet part 17b, and can be a part that is substantially non-magnetic and has almost no polarity. For example, the partition wall can be a non-magnetic substance, or air, etc. The non-magnetic partition wall can be expressed as a "Neutral Zone" or a "neutral region". The partition wall can be a part that is artificially formed when magnetizing the first magnet part 17a and the second magnet part 17b.

For example, when the drive signal (dV) or bias signal of the Hall sensor 61 is 1 [mA], the output (VH) of the Hall sensor 61 of the first position sensor 170 can be -20 [mV] to +20 [mV]. And in the case of temperature compensation for the output (VH) of the Hall sensor 61 having a negative slope with respect to the ambient temperature change, the output (VH) of the Hall sensor 61 of the first position sensor 170 can be 0 [mV] to +30 [mV].

[0273] When the output of the Hall sensor 61 of the first position sensor 170 is displayed in the xy coordinate system, the reason for setting the output range of the Hall sensor 61 of the first position sensor 170 to the first quadrant (for example, 0 [mV] to +30 [mV]) is as follows. It can be transmitted to the control units 830 and 780. It can perform temperature compensation.

[0274] For example, when the drive signal (dV) or bias signal of the Hall sensor 61 is 1 [mA], the output (VH) of the Hall sensor 61 of the first position sensor 170 can be -20 [mV] to +20 [mV]. The output (VH) of the Hall sensor 61 of the first position sensor 170 can be -20 [mV] to +20 [mV]. It can be +20 [mV].

[0275] And for the temperature compensation for the output (VH) of the Hall sensor 61 having a negative slope with respect to the ambient temperature change, the output (VH) of the Hall sensor 61 of the first position sensor 170 can be 0 [mV] to +30 [mV]. For the temperature compensation for the output (VH) of the Hall sensor 61 having a negative slope with respect to the ambient temperature change, the output (VH) of the Hall sensor 61 of the first position sensor 170 can be 0 [mV] to +30 [mV].

[0276] When the output of the Hall sensor 61 of the first position sensor 170 is displayed in the xy coordinate system, the reason for setting the output range of the Hall sensor 61 of the first position sensor 170 to the first quadrant (for example, 0 [mV] to +30 [mV]) is as follows. The reason is as follows.

[0277] The output of the Hall sensor 61 in the first quadrant of the xy coordinate system and the output of the Hall sensor 62 in the third quadrant of the xy coordinate system change according to the change in the ambient temperature. The outputs of the Hall sensors 61 on the first and third quadrants move in opposite directions. When both surfaces are used in the AF drive control section, the accuracy and reliability of the Hall sensor decreases. Therefore, in order to accurately compensate for changes in ambient temperature, a certain range of the first quadrant is The position sensor 170 can be the output range of the Hall sensor 61 .

Incidentally, the first position sensor 170 can receive the provision of power supply signals (VDD, GND) via the first and second terminals

[0379] B1 and B2 of the circuit board 190. For example, the first terminal B1 of the circuit board 190 can be either the VDD terminal or the GND terminal, and the second terminal B2 of the circuit

[0380] board 190 can be the remaining one of the VDD terminal and the GND terminal. Also, a clock signal (SCL) and a data signal (SDA) can be provided to the third and fourth support members 220-3 and 220-4 via the third and fourth

A power signal (GND) can be provided to the first position sensor 170 via the second terminal 251-2 of the circuit board 250, the second support member 220-2, the second upper elastic unit 150-2, and the second terminal B2 of the circuit board 190.

[0383] Also for example, a clock signal (SCL) can be provided to the first position sensor 170 via the third terminal 251-3 of the circuit board 250, the third support member 220-3, the third upper elastic unit 150-3, and the third terminal B3 of the circuit board 190. A data signal (SDA) can be provided to the first position sensor 170 via the fourth terminal 251-4 of the circuit board 250, the fourth support member 220-4, the fourth upper elastic unit 150-4, and the fourth terminal B4 of the circuit board 190.

[0384] Each of the fifth and sixth terminals B5 and B6 of the circuit board 190 is connected or coupled to any one of the corresponding second outer frames 162-1 in the first and second lower elastic units 160-1 and 160-2.

[0385] The second outer frame 162-1 of the first lower elastic unit 160-1 can include a first bonding portion 81a for bonding the fifth terminal B5 of the circuit board 190 by soldering or a conductive adhesive member. Also, the second outer frame 162-1 of the second lower elastic unit 160-2 can include a second bonding portion 81b for bonding the sixth terminal B6 of the circuit board 190 by soldering or a conductive adhesive member. ​​​​​​​​​​​​​​​It can be provided with a second bonding portion 81b for connecting the terminal B5.

[0386] For example, the second outer frame 162-1 of the first lower elastic unit 160-1 includes a first hole 82a (or a first groove) into which the fifth terminal B5 of the circuit board 190 is inserted or arranged. The second outer frame 162-1 of the second lower elastic unit 160-2 includes a second hole 82b (or a second groove) into which the sixth terminal B6 of the circuit board 190 is inserted or arranged. It can be provided.

[0387] For example, each of the first and second holes 82a and 82b can penetrate the second outer frame 161-1 and have an opening that is open on one side surface of the second outer frame 161-1. However, it is not limited to this. In other embodiments, the second outer frame 161-1 may not have an opening that is open on one side surface.

[0388] With the fifth terminal B5 (or the sixth terminal B6) of the circuit board 190 inserted into the first groove 82a (or the second groove 82b) of the second outer frame 162-1 of the first lower elastic unit 16 0-1, the fifth terminal B5 (or the sixth terminal B6) is bonded to the first bonding portion 81a (or the second bonding portion 81b) provided with the first groove 82a (or the second groove 82b) by soldering or a conductive adhesive member, so that the bonding area can be increased and the bonding force and soldering property between the two can be improved.

[0389] Referring to FIG. 12, one end (for example, the lower end or the lower surface) of each of the fifth and sixth terminals B5 and B6 is the second outer frame 1 of the first and second lower elastic units 160-1 and 160-2. ​​​​​It can be positioned lower than the lower end or the lower surface of 62-1. Since FIG. 12 is a bottom view , the lower surface of each of the fifth and sixth terminals B5 and B6 can be expressed as being positioned lower than the lower end or the lower surface of the second outer frame 162-1. This is to improve the soldering property between one end of each of the fifth and sixth terminals B 5 and B6 and the first and second bonding portions 81a and 81b of the first and second lower elastic units 160-1 and 160-2.

[0390] Also, referring to FIG. 12, the housing 140 can include a groove 31 recessed from the lower surface of the first side portion 141-1. For example, the bottom surface of the groove 31 of the housing 140 can have a step with the lower surface of the housing 140 in the optical axis direction . For example, the bottom surface of the groove 31 of the housing 140 can be positioned higher than the lower surface of the housing 140.

[0391] The groove 31 of the housing 140 can overlap with the first and second bonding portions 81a and 81b of the first and second lower elastic units 160-1 and 160-2 in the optical axis direction.

[0392] Also, the groove 31 of the housing 140 overlaps with the holes 82a and 82b of the second outer frame 162-1 of the first and second lower elastic units 160 -1 and 160-2 in the optical axis direction, but is not limited thereto. In other embodiments, the two may not overlap.

[0393] The groove 31 of the housing 140 can increase the area where the fifth and sixth terminals B5 and B6 of the circuit board 190 are released from the housing 140, facilitating soldering or conductivity . A space where the connecting member can be seated can be secured, improving solderability. The degree to which the solder protrudes below the lower surface of the second outer frame 162-1 can be reduced. The second coil 230, circuit board 250, or the space interference with the base 210 disposed below the lower elastic unit can be suppressed or prevented.

[0394] Also, the lower surface 11c of the first magnet 130 disposed on the seating portion 141a of the housing 140 can be lower than the lower surfaces of the second outer frames 162-1 to 162-3 of the first and second lower elastic units 160-1 and 160-2, but is not limited thereto. In other embodiments, the lower surface 11c of the first magnet 130 may be higher than or at the same height as the lower surfaces of the second outer frames 162-1 to 162-3 or the lower surface of the housing 140.

[0395] To separate the first magnet 130 from the second coil 230 and the circuit board 250, the other end of the support member 220 can be coupled to the circuit board 250 (or the circuit member 231) at a position lower than the lower surface 11c of the first magnet 130.

[0396] The support member 220 is conductive and can be a member supported by elasticity, for example, a suspension wire, a leaf spring, or a coil spring, etc. In other embodiments, the support member 220 may be integrally formed with the upper elastic member 150.

[0397] Next, the base 210, circuit board 250, second coil 230, and adhesive member 290 will be described.

[0399] When the cover member 300 is adhesively fixed, the base 210 can be provided with a locking portion 211 to which an adhesive can be applied. At this time, the locking portion 211 can guide the side plate 302 of the cover member 300 coupled to the upper side, and the lower end of the side plate 302 of the cover member 300 can contact the locking portion 211. The locking portion 211 of the base 210 and the lower end of the side plate 302 of the cover member 300 can be adhesively fixed by an adhesive or the like. A support portion 255 can be provided in the region of the base 210 facing the terminal surface 253 where the terminals 251-1 to 251-n of the circuit board 250 are provided. The support portion 255 can support the terminal surface 253 of the circuit board 250 on which the terminals 251-1 to 251-n of the circuit board 250 are formed. For example, the support portion 255 can be in the form of a groove recessed from the outer surface of the base 210, but is not limited thereto, and in other embodiments, it can be on the same plane as or protrude from the outer surface of the base 210.

[0400] A protrusion 48 or a projection extending or protruding from the outer surface of the base 210 can be formed on the side surface of the circuit board 250, and on the outer surface of the base 210, a protrusion of the circuit board 250

[0401] ​​​​​​​​​A groove 28 or a coupling groove having a shape corresponding to a position corresponding to the portion 48 may be formed. The protruding portion 48 of the circuit board 250 can be disposed, coupled, or seated in the groove 28 of the base 210.

[0402] The base 210 can include escape portions 212-1 to 212-4 for avoiding spatial interference with the support member 220.

[0403] For example, the base 210 can have escape portions 212-1 to 212-4 in a corner region corresponding to a corner of the cover member 300. The escape portions 212-1 to 212-4 can be in the form of grooves, holes, or the like for avoiding spatial interference with the support members 220-1 to 220-4 and the adhesive member (or solder 902).

[0404] For example, the escape portions 212-1 to 212-4 of the base 210 can be in the form of concave grooves that recess from the outer surface of the corner of the base 210 toward the center of the base 210. The escape portions 212-1 to 212-4 of the base 210 can be open to the upper and lower surfaces of the base 210.

[0405] For example, the escape portions 212-1 to 212-4 of the base 210 can expose a part of the lower surface of the circuit board 250 (for example, the first region or the corner region). In other embodiments, the escape portions of the base 210 can expose a part of the lower surface of the circuit member 231 (for example, the first region or the corner region).

[0406] The inner side surfaces of the corners of the cover member 300 and the escape portions 212-1 to 212-4 of the base 210 can be coupled to each other by the adhesive member 290.

[0407] ​​​​​​​​​​​For example, the adhesive member 290 can be disposed in a partial region (e.g., the first region or a corner region) of the lower surface of the circuit board 250.

[0408] For example, the adhesive member 290 can be disposed on at least one of the escape portions 212-1 to 212-4, a partial region (e.g., the first region or a corner region) of the lower surface of the circuit board 250, and a partial region of the lower surface of the base 210 adjacent to the escape portions 212-1 to 212-4. For example, a partial region of the lower surface of the base 210 can include the stepped portion 320. In still other embodiments, for example, a partial region of the lower surface of the base 210 can include the stepped portion 320 and a region of the lower surface of the base 210 adjacent to the stepped portion 320. In still other examples, for example, a partial region of the lower surface of the base 210 can include the stepped portion 320 and a region of the lower surface of the base 210 adjacent to the stepped portion 320.

[0409] In addition, mounting grooves 215-1 and 215-2 on which the second position sensor 240 can be disposed can be provided on the upper surface of the base 210.

[0411] For example, the first mounting groove 215-1 of the base 210 can be formed on the upper surface of the base 210 located between any one of the escape portions 212-3 and the protrusion 19, and the second mounting groove 215-2 can be formed on the upper surface of the base 210 located between any one of the other escape portions 212-4 and the protrusion 19.

[0412] ​​​​​​​​​​​ For example, on the lower surface of the base 210, a mounting portion (not shown) for mounting the filter 610 of the camera module 200 may be formed.

[0413] Also, on the upper surface around the opening (C3) of the base 210, a protrusion 19 for coupling with the opening (C2) of the circuit board 250 and the opening (C1) of the circuit member 231 can be provided.

[0414] The protrusion 19 of the base 210 may have the same shape as the opening (C3), for example, circular, but is not limited thereto. For example, the protrusion 19 may be a single circular shape, but is not limited thereto, and may include a plurality of separated portions.

[0415] The base 210 can be provided with a protrusion 32 protruding from the upper surface for coupling with the coupling groove 33 of the circuit board 250.

[0416] For example, the coupling groove 33 of the circuit board 250 can be formed on the inner surface of the circuit board 250 formed by the opening (C2) and be in a form sunken from the inner surface of the circuit board 250. Also, the protrusion 32 of the base 210 can correspond or be opposed to the coupling groove 33 of the circuit board 250 in the optical axis direction, and the protrusion 32 can have a shape corresponding or matching the coupling groove 33 of the circuit board 250. For example, the protrusion 32 can contact the outer surface of the protrusion 19 of the base 210.

[0417] The second coil 230 can be disposed on the upper part of the circuit board 250, and the OIS position sensors 240a, 240b can be disposed in the mounting grooves 215-1, 215-2 of the base 210 located under the circuit board 250. ​

[0418] The second position sensor 240 includes first and second OIS position sensors 240a and 240b. The OIS position sensors 240a and 240b can sense the displacement of the OIS movable part in a direction perpendicular to the optical axis.

In the embodiment, since the drive signal is directly provided from the first position sensor 170 to the first coil 120, when compared with the case where the drive signal is directly provided to the first coil 120 via the circuit board 250, the number of support members can be reduced and the electrical connection structure can be simplified.

[0477] Also, since the first position sensor 170 can be realized by a driver IC capable of temperature measurement, the output of the Hall sensor is compensated to have a minimum change due to temperature change, or the output of the Hall sensor is compensated to have a certain slope due to temperature change, so that the accuracy of AF driving can be improved regardless of temperature change.

[0478] The cover member 300 houses the bobbin 110, the first coil 120, the first magnet 130, the housing 140, the upper elastic member 150, the lower elastic member 160, the first position sensor 170, the second magnet 180, the circuit board 190, the support member 220, the second coil 230, the second position sensor 240, and the circuit board 250 in the accommodation space formed together with the base 210.

[0479] The cover member 300 may be in a box shape with an open bottom, including an upper plate 301 and side plates 302. The lower part of the cover member 300 (for example, the lower part of the side plate 302) can be coupled to the base 210 (for example, the locking part 211 or / and the escape parts 212-1 to 212-4). The shape of the upper plate 301 of the cover member 300 may be circular or polygonal, for example, square or octagonal, etc., but is not limited thereto.

[0480] The cover member 300 can be provided with an opening on the upper plate 301 to expose a lens (not shown) coupled to the bobbin 110 to external light. The material of the cover member 300 may be a non-magnetic material such as SUS to prevent the phenomenon of adhering to the first magnet 130, but it can be formed of a magnetic material to improve the electromagnetic force between the first coil 120 and the first magnet 130. It may have a yoke function.

[0481] To reduce the length of the path through which the power supply signals (GND, VDD) are transmitted to the first position sensor 170, the following configuration can be provided. First, the first and second terminals B1, B2 of the circuit board 190 for providing the power supply signals (GND, VDD) are electrically connected to the first and second support members 220-1, 220-1 disposed at two corner portions 142-1, 142-2 adjacent to the first side portion 141-1 of the housing 140 where the first position sensor 170 is disposed, thereby reducing the path.

[0482] First, the first and second terminals B1, B2 of the circuit board 190 for providing the power supply signals (GND, VDD) are disposed at two corner portions 142-1, 142-2 adjacent to the first side portion 141-1 of the housing 140 where the first position sensor 170 is disposed. The first and second support members 220-1, 220-1 are electrically connected to the first and second support members 220-1, 220-1, thereby reducing the path. can be reduced.

[0483] Also, by disposing the first and second terminals B1, B2 of the circuit board 190 on the main body portion S1 of the circuit board 190, the path can be reduced.

[0484] Also, the first terminal B1 of the circuit board 190 is disposed at one end of the circuit board 190 so as to overlap in the optical axis direction with the first corner portion 142-1 of the housing 140, and the second terminal B2 of the circuit board 190 is disposed at the other end of the circuit board 190 so as to overlap in the optical axis direction with the second corner portion 142-2 of the housing 140, thereby reducing the path.

[0485] Also, the separation distance (for example, the shortest separation distance) between the first terminal B1 of the circuit board 190 and the first support member 220-1 is the separation distance (for example, the shortest separation distance) between the third terminal B3 of the circuit board 190 and the first support member 220-1 and the separation distance between the fourth terminal B4 of the circuit board 190 and the first support member ​​​​​​​​It is smaller than the separation distance (for example, the shortest separation distance) from 220-1.

[0486] Also, the separation distance (for example, the shortest separation distance) between the second terminal B2 of the circuit board 190 and the second support member 220-2 is the separation distance (for example, the shortest separation distance) between the third terminal B3 of the circuit board 190 and the second support member 220-2 and the separation distance (for example, the shortest separation distance) between the fourth terminal B4 of the circuit board 190 and the second support member 220-1.

[0487] Due to the shortening of the path for the reasons described above, the lengths of the first and second extension parts P1 and P2 can be reduced, thereby reducing the resistance of the path (for example, the resistance of the first and second upper elastic units 150-1 and 150-2).

[0488] Also, each of the first upper elastic unit 150-1 connected to the first terminal B1 of the circuit board 190 and the second upper elastic unit 150-2 connected to the second terminal B2 has a first outer frame coupled to the housing 140, but does not have a first inner frame 151 and a first frame connection part. Therefore, compared with the second and fourth upper elastic units 150-3 and 150-4, the resistance is reduced. The resistance is reduced.

[0489] For the reasons as described above, the embodiment reduces the length of the path through which the power supply signals (GND, VDD) are transmitted to the first position sensor 170, thereby reducing the resistance of the path ( for example, the resistance of the first and second upper elastic units 150-1 and 150-2), thereby preventing the power supply signals (GND, VDD) from decreasing, reducing power consumption, and reducing the operating voltage of the driver IC of the first position sensor 170. It can be prevented from decreasing, and power consumption can be reduced, and the operating voltage of the driver IC of the first position sensor 170 can be reduced. By reducing the length of the path through which the power supply signals (GND, VDD) are transmitted to the first position sensor 170, the resistance of the path ( It is possible to do so.

[0490] In the embodiment, the electrical connections between the first to fourth extension parts P1 to P4 of the elastic units 150-1 to 150-4 are In order to facilitate soldering for the gas-tight joint and improve the solderability, the first to sixth The terminals B1 to B6 may be disposed on the second surface 19a of the circuit board 190.

[0491] If the first to sixth terminals B1 to B6 are arranged on the first surface 19b of the circuit board 190, , soldering becomes difficult, solderability deteriorates, and foreign matter (e.g. For example, contaminants can flow into the lens driving device 100, which can cause This can induce a malfunction of the lens driving device.

[0492] The third and fourth terminals B3 and B4 are disposed between the first terminal B1 and the second terminal B2. To reduce the path of the circuit board 190, the first corner portion 142-1 and the Since the second corner portion 142-2 has an extending or protruding structure, the third upper elastic unit 150-3 and a part of each of the fourth upper elastic units 150-3 (for example, the third extension portion P3 The fourth extension portion P4) passes through the circuit board 190 and is coupled to the third and fourth terminals B3 and B4. It can be done.

[0493] The fifth and sixth terminals B5 and B6 of the circuit board 190 are connected to the lower elastic units 160-1 and 160-2. 0-2, the extension S2 of the circuit board 190 can be disposed thereon. Cut.

[0494] In the embodiment, the magnetic field between the second and third magnets 180, 185 and the first magnet 130 Since the magnetic field interference is reduced, the reduction in the AF driving force caused by the magnetic field interference can be prevented, and as a result, That is, a desired AF driving force can be obtained without providing a separate yoke.

[0495] As described above, in the embodiment, the number of support members can be reduced, and by reducing the number of support members the size of the lens driving device can be reduced.

[0496] Also, since the number of support members is reduced, the resistance of the support members can be reduced, and the consumption current can be reduced, and the sensitivity of the OIS driving can be improved.

[0497] Also, in order to obtain the same elastic force instead of reducing the number of support members, the thickness of the support members can be increased so that by increasing the thickness of the support members, the influence on the OIS movable part by an external impact can be reduced.

[0505] Referring to FIG. 18A, for example, the diameters (R) of the escape portions 212-1 to 212-4 can increase as going from the center 201 of the base 210 toward the corner direction of the base 210. Referring to FIG. 18A, for example, the diameters (R) of the escape portions 212-1 to 212-4 can increase as going from the center 201 of the base 210 toward the corner direction of the base 210. Referring to FIG. 18A, for example, the diameters (R) of the escape portions 212-1 to 212-4 can increase as going from the center 201 of the base 210 toward the corner direction of the base 210.

[0506] For example, the center 201 of the base 210 can be the spatial center of the base 210. For example, the center 201 of the base 210 can be the center of the opening (C3) of the base 210.

[0510] shape. The base 210 can be provided with a groove 310 formed on the upper surface 210A of the base 210 around the escape portion 212-2. The groove 310 of the base 210 can be located below the lower surface of the circuit board 250. For example, the groove 310 can be arranged between the circuit board 250 and the base 210.

[0511]

[0512] The groove 310 of the base 210 may be alternatively expressed as an "adhesive member discharge groove", a "discharge groove", a "guide groove", an "adhesive member discharge guide groove", or a "step portion".

[0513] ​​​​​​​​The groove 310 of the base 210 serves to suppress or block the inflow of the adhesive member 290 toward one end of the member 220 through the hole 250a of the circuit board 250.

[0514] The groove 310 of the base 210 may be in a form recessed from the upper surface 210A of the base 210, for example, a recess or a groove. Here, the upper surface 210A of the base 2 10 is a surface corresponding to or facing the lower surface of the circuit board 250 in the optical axis direction and can be. For example, the upper surface 210A of the base 210 can be a surface in contact with the lower surface of the circuit board 250 and can be.

[0515] The groove 310 of the base 210 can be separated from the outer surface 311 of the corner portion 11 of the base 210 formed by the escape portion 212-2 or the escape portion 212-2.

[0516] For example, the groove 310 of the base 210 has a step with the upper surface 210A of the base 210 in the optical axis direction a bottom surface 10A, a first side wall (10B or "first side surface") connecting one side of the bottom surface 10A and the upper surface 210A of the base 210, and the other side of the bottom surface 10A and the upper surface 210A of the base 210 and can include a second side wall (10C or "second side surface") connecting them.

[0517] Or, for example, the groove 310 has a first surface 10A having a step with the upper surface 210A of the base 210 , and a second surface 10B, 1 0C connecting the first surface 10A and the upper surface 210A of the base 210 may be included.

[0518] For example, the bottom surface 10A can be located lower than the upper surface 210A of the base 210. For example, based on the lower surface 210B of the base 210, the height of the bottom surface 10A is the upper surface of the base 210 It may be lower than the height of 210A. For example, the first side wall 10B and the second side wall 10B may face each other or be opposite to each other.

[0519] For example, the bottom surface 10A can be parallel to the upper surface 210A of the base 210, and the first inner angle formed by the first side wall 10B and the bottom surface 10A may be a right angle, and the second inner angle formed by the second side wall 10C and the bottom surface 10A may be a right angle, but is not limited thereto. In other embodiments, each of the first inner angle and the second inner angle may be an obtuse angle or an acute angle.

[0521] For example, the groove 310 can include at least one of a first opening HO1 opened to any one of the outer surfaces 213A of the base 210 adjacent to the escape portion 212-2 and a second opening HO2 opened to the other outer surface 213B of the base 210 adjacent to the escape portion 212-2. This is to allow the adhesive member 290 to escape outside the base 210 through the first opening HO1 and the second opening HO2.

[0522] The distance from one end (or the first opening HO1) to the other end (or the second opening HO2) of the groove 310 may be greater than the width of the groove 310 (or the width of the bottom surface 10A).

[0523] For example, the shape of the groove 310 can correspond to or match the shape of the outer surface 311 of the corner portion of the base 210 or the shape of the escape portion.

[0524] ​​​​​​​​​ The shape of the outer surface 311 of the corner portion of the base 210 can include at least one bent portion or a rounded portion. For example, referring to FIG. 18A, the shape of the outer surface 311 of the corner portion of the base 210 can include three bent portions or rounded portions, and can be symmetric about the bent portion and the rounded portion located in the middle, but is not limited thereto. For example, referring to FIG. 18A, the shape of the outer surface 311 of the corner portion of the base 210 can include three bent portions or rounded portions, and can be symmetric about the bent portion and the rounded portion located in the middle, but is not limited thereto.

[0525] For example, a partition wall 330 can be present between the groove 310 and the escape portion 212-2 of the base 210. The partition wall 330 can serve to suppress or block the penetration of the adhesive member 290 into the hole 250a of the circuit board 250. For example, a partition wall 330 can be present between the groove 310 and the escape portion 212-2 of the base 210. The partition wall 330 can serve to suppress or block the penetration of the adhesive member 290 into the hole 250a of the circuit board 250.

In other embodiments, a part of the adhesive member 290 may not be disposed or remain in the groove 310 of the base 210.

[0527] Referring to FIGS. 18B and 18C, a step portion 320 having a step with the lower surface 210B of the base 210 in the optical axis direction can be formed on the lower surface of the corner portion of the base 210 adjacent to the escape portions 212-1 to 212-4. The step portion 320 may be alternatively expressed as a "groove" or a "grooved portion". Referring to FIGS. 18B and 18C, a step portion 320 having a step with the lower surface 210B of the base 210 in the optical axis direction can be formed on the lower surface of the corner portion of the base 210 adjacent to the escape portions 212-1 to 212-4. The step portion 320 may be alternatively expressed as a "groove" or a "grooved portion". Referring to FIGS. 18B and 18C, a step portion 320 having a step with the lower surface 210B of the base 210 in the optical axis direction can be formed on the lower surface of the corner portion of the base 210 adjacent to the escape portions 212-1 to 212-4. The step portion 320 may be alternatively expressed as a "groove" or a "grooved portion". Referring to FIGS. 18B and 18C, a step portion 320 having a step with the lower surface 210B of the base 210 in the optical axis direction can be formed on the lower surface of the corner portion of the base 210 adjacent to the escape portions 212-1 to 212-4. The step portion 320 may be alternatively expressed as a "groove" or a "grooved portion".

[0528] For example, the step portion 320 can be formed on the lower surface of the base 210 around the escape portions 212-1 to 212-4. Alternatively, the step portion 320 can be formed so as to cover at least a part of the escape portions 212-1 to 212-4. For example, the step portion 320 can be formed on the lower surface of the base 210 around the escape portions 212-1 to 212-4. Alternatively, the step portion 320 can be formed so as to cover at least a part of the escape portions 212-1 to 212-4. For example, the step portion 320 can be formed on the lower surface of the base 210 around the escape portions 212-1 to 212-4. Alternatively, the step portion 320 can be formed so as to cover at least a part of the escape portions 212-1 to 212-4.

[0529] For example, the step portion 320 can be disposed between the lower surface of the base 210 and the adhesive member 290. This is possible.

[0530] For example, the step portion 320 has a first surface 321 with a step H2 from the lower surface 210B of the base 210 in the optical axis direction, and a second surface 322 connecting the first surface 321 and the lower surface 210B of the base 210. It can include these.

[0531] The first surface 321 of the step portion 320 can be positioned higher than the lower surface 210B of the base 210. For example, the length in the optical axis direction up to the first surface 321 of the step portion 320 based on the upper surface 210A of the base 210 can be smaller than the length in the optical axis direction up to the lower surface 210B of the base 210 based on the upper surface 210A of the base 210. It may be smaller.

[0532] For example, the distance from the upper surface 210A of the base 210 to the bottom surface 10A of the groove 310 (or the depth H1 of the groove) may be smaller than or the same as the step H2 of the step portion 320 (H1 ≦ H2). In other embodiments, H1 > H2 may also be possible. For example, H2 can be the height of the first surface 321 based on the lower surface of the base 210. This is possible.

[0533] For example, the first surface 321 of the step portion 320 can be in contact with the escape portions 212-1 to 212-4. Or for example, the first surface 321 of the step portion 320 can be in contact with the outer surface 311 of the corner portion 11 of the base 210 formed by the escape portion 212-2. This is possible.

[0534] For example, in the optical axis direction, the step portion 320 can overlap with the groove 310 of the base 210. This is possible.

[0535] For example, one end of the step portion 320 can be in contact with any one of the outer surfaces 213A of the base 210 adjacent to the escape portion (for example, 212-2), and the other end of the step portion 320 can be in contact with the other outer surface 213B of the base 210 adjacent to the escape portion (for example, 212-2). This is to increase the contact area between the step portion 320 of the base 210 and the adhesive member 290, improve the adhesive force between the base 210 and the cover member 300, and lengthen the flow path of the adhesive member 290, so as to prevent the adhesive member 290 from penetrating the upper surface of the circuit board 250 and flowing into the upper part of the hole 250a of the circuit board 250. In other embodiments, at least one of one end and the other end of the step portion 320 may be separated from and not in contact with the outer surfaces 213A and 213B of the base 210 adjacent to the escape portion (for example, 212-2). For example, the width W2 of the first surface 321 of the step portion 320 may be larger than the width W1 of the groove 310 of the base 210. This is to increase the contact area between the step portion 320 of the base 210 and the adhesive member 290, improve the adhesive force between the base 210 and the cover member 300, and make the flow path of the adhesive member 290 complex and long, so as to prevent the adhesive member 290 from penetrating the upper surface of the circuit board 250 and flowing into the upper part of the hole 250a of the circuit board 250.
