For example, the optical instrument according to the embodiment may include a smart phone and a portable terminal equipped with a camera. 
       FIG. 1  is an exploded perspective view of a camera device  200  according to an embodiment. 
     Referring to  FIG. 1 , the camera device  200  may include a lens or a lens barrel  400 , a lens moving apparatus  100 , a filter  610 , a holder  600 , a circuit board  800 , an image sensor  810  and a foreign-substance-blocking member  310 . Here, the term “camera device” may be interchangeably used with “camera module”, “imaging unit” or “photographing unit”, and the term “holder” may be interchangeably used with “sensor base”. The term “foreign-substance-blocking member” may be interchangeably used with “epoxy” or “adhesive member”. 
     The camera device  200  may further include a blocking member  1500  disposed on the filter  610 . 
     Furthermore, the camera device  200  may further include an adhesive member  612 . 
     In addition, the camera device  200  may further include a motion sensor  820 , a controller  830  and a connector  840 . 
     The lens or the lens barrel  400  may be mounted in the bobbin  110  of the lens moving apparatus  100  and may be moved in the optical-axis direction. 
     The holder  600  may be disposed under the base  210  of the lens moving apparatus  100 . 
     For example, the holder  600  may be disposed under the lens or the lens barrel  400 . 
     The filter  610  may be mounted on the holder  600 . The holder  600  may be depressed from the upper surface thereof, and may include a seating portion  500  in which the filter  610  is seated. The filter  610  may be disposed in the seating portion  500 . 
     Although the seating portion  500  may be embodied as a recess, cavity or hole, which is depressed from the upper surface thereof, the disclosure is not limited thereto. In another embodiment, the seating portion  500  may be embodied as a projecting portion, which projects from the upper surface of the holder  600 . 
     The adhesive member  612  may couple or attach the base  210  of the lens moving apparatus  100  to the holder  600 . For example, the adhesive member  512  may be disposed between the lower surface of the base  210  and the upper surface of the holder  600  so as to attach the two surfaces to each other. 
     The adhesive member  612  may serve to prevent foreign substances from entering the lens moving apparatus  100  as well as to perform attachment as described above. For example, the adhesive member  612  may be epoxy, thermohardening adhesive, UV hardening adhesive, or the like. 
     The seating portion in the holder  600  may include an inner surface and a bottom surface. 
     The filter  610  may be disposed on the bottom surface of the seating portion  500 . 
     The holder  600  may have a bore  501 , which is formed in a region on which the filter  610  is mounted or disposed so as to allow the light that passes through the filter  610  to be incident on the image sensor  810 . 
     For example, the bore  501  may be formed through the holder  600  in the optical-axis direction, and may be alternatively referred to as a through hole. For example, the bore  600  may be formed through the center of the holder  600  and may be disposed so as to correspond to or face the image sensor  810 . 
     For example, the bore  501  may be provided in the bottom surface of the seating portion  500 , and may have an area smaller than that of the filter  610 . 
     For example, the filter  610  may be disposed on the bottom surface of the seating portion  500  in the holder  600 . The filter  610  may serve to prevent light in a specific frequency band, among the light passing through the lens barrel  400 , from entering the image sensor  810 . In another embodiment, the filter  610  may be disposed in a seating recess formed in the lower surface of the base  210 . 
     Although the filter  610  may be, for example, an infrared-blocking filter, the disclosure is not limited thereto. In another embodiment, the filter  610  may be an infrared-transmitting filter. 
     For example, the filter  610  may be disposed so as to be parallel to the x-y plane perpendicular to the optical axis OA. 
     The filter  610  may be attached to the bottom surface of the seating portion in the holder  600  by means of an adhesive member (not shown) such as UV epoxy. 
     The circuit board  800  may be disposed under the holder  600 , and the image sensor  810  may be mounted or disposed on the circuit board  800 . The image sensor  810  may be a region on which an image included in the light passing through the filter  610  is formed. 
     The circuit board  800  may include various circuits, elements, controllers and the like in order to convert the image formed on the image sensor  810  into an electrical signal and transmit the electrical signal to an external device. 
     The circuit board  800  may have a circuit pattern formed thereon, which is conductively connected to the image sensor  810  and to various elements. 
     The holder  600  may be disposed on the circuit board  800  and may accommodate the filter  610  therein. The holder  600  may support the lens moving apparatus  100  positioned thereabove. The holder  600  may be alternatively referred to as a sensor base. 
     The lower surface of the base  210  of the lens moving apparatus  100  may be disposed on the upper surface of the holder  600 . For example, the lower surface of the base  210  of the lens moving apparatus  100  may be in contact with the upper surface of the holder  600  and may be supported by the upper surface of the holder  600 . 
     The holder  600  may have the seating portion  500 , which is depressed from the upper surface of the holder  600 , and the seating portion  500  may have the inner surface and the bottom surface. At least some of the inner surface of the seating portion  500  may face the lateral surface of the filter  610 . 
     The holder  600  may be alternatively referred to as a first holder, and the circuit board  800  may be alternatively referred to as a second holder. 
     The image sensor  810  may receive an image included in light, which enters the image sensor  810  through the lens moving apparatus  100 , and may convert the received image into an electrical signal. 
     For example, the image sensor  810  may have an imaging area for detecting the light passing through the lens or the lens barrel  400 . Here, the imaging area  811  may be alternatively referred to as an effective area, a light-receiving area or an active area. 
     The filter  610  and the image sensor  810  may be spaced apart from each other so as to face each other in the direction of the optical-axis OA or in the first direction. 
     The filter  610  may be disposed or seated on the bottom surface of the seating portion  500 . For example, the lower surface of the filter  610  may be in contact with the bottom surface of the seating portion  500 . 
     The blocking member  1500  may be disposed on the upper surface of the filter  610 . The blocking member  1500  may be alternatively referred to as a masking portion. 
     The blocking member  1500  may have a bore, for example, a through hole, which is formed at a location corresponding to the image sensor  810  in the optical-axis direction. 
     For example, the blocking member  1500  may be disposed on the peripheral area of the upper surface of the filter  610 , and may serve to prevent at least part of the light, which enters the peripheral area of the filter  610  through the lens or the lens barrel  400 , from passing through the filter  610 . For example, the blocking member  1500  may be coupled or attached to the upper surface of the filter  610 . 
     For example, the filter  610  may be configured to have a quadrilateral shape when viewed in the optical-axis direction, and the blocking member  1500  may be formed along the peripheral sides of the upper surface of the filter  610  so as to define a symmetrical shape with respect to the filter  610 . Here, the blocking member  1500  may have a constant width at the peripheral sides of the upper surface of the filter  1610 . 
     For example, the blocking member  1500  may have a quadrilateral shape, and may have a quadrilateral bore, without being limited thereto. 
     The blocking member  1500  may be made of an opaque material. 
     The blocking member  1500  may be made of an opaque adhesive material, which is applied to the filter  610 , or may be embodied as a film sheet, which is attached to the filter  610 . 
     The filter  610  and the image sensor  810  may be disposed so as to face each other in the optical-axis direction, and at least a portion of the blocking member  1500  may overlap terminals  41   a  and  41   b  and/or wires  51   a  and  51   b  disposed on the circuit board  800 . The blocking member  1500  may not overlap the imaging area  811  of the image sensor  810  in the optical-axis direction. 
     The blocking member  1500 , which is disposed on the peripheral area of the upper surface of the filter  610 , may serve to prevent an undesired portion of the incident light  1010 , which is incident on the image sensor  810  through the lens or the lens barrel  1400 , from entering the image sensor  810 . 
     The wires  51   a  and  51   b  and the terminals  41   a  and  41   b  of the circuit board  800  may be made of a conductive material, for example gold, silver, copper, copper alloy, or the like. The conductive material may have a property of reflecting light. 
     Specifically, the light that has passed through the filter  610  may be reflected by the terminals  41   a  and  41   b  of the circuit board  800  and the wires  51   a  and  51   b , and the reflected light may cause momentary blazing, that is, a flare phenomenon. The flare phenomenon may distort an image formed on the image sensor  810  or deteriorate the quality of the image. 
     Since the blocking member  1500  is disposed such that at least a portion thereof overlaps the terminals  41   a  and  41   b  and/or the wires  51   a  and  51   b  in the optical-axis direction, it is possible to block part of the light that has passed through the lens or the lens barrel  400  and is then directed toward the terminals  41   a  and  41   b  of the circuit board  800  and/or the wires  51   a  and  51   b , thereby preventing the image formed on the image sensor  810  from being distorted or deteriorated in image quality. 
     The motion sensor  820  may be mounted or disposed on the circuit board  800 , and may be conductively connected to the controller  830  via a circuit pattern provided on the circuit board  800 . 
     The motion sensor  820  may output angular velocity information about motion of the camera device  200 . The motion sensor  820  may be embodied as a biaxial or triaxial gyro sensor or an angular velocity sensor. 
     The controller  830  may be mounted or disposed on the circuit board  800 . 
     The circuit board  800  may be conductively connected to the lens moving apparatus  100 . For example, the circuit board  800  may be conductively connected to the circuit board  250  of the lens moving apparatus  100 . 
     For example, a drive signal may be supplied to each of a first coil  120  and a second coil  230  of the lens moving apparatus  100 , and may be supplied to an AF position sensor (or an OIS position sensor). The output of the AF position sensor (or OIS position sensor) may be transmitted to the circuit board  800 . 
     The connector  840  may be conductively connected to the circuit board  800  and may include a port, which is to be conductively connected to an external device. 
     The camera device  200  may be one of an AF (autofocus) camera module and an OIS (optical image stabilizer) camera module. The AF camera module serves to fulfil only an autofocusing function, and the OIS camera module serves to fulfil both an autofocusing function and an OIS function. 
     For example, the lens moving apparatus  100  may be an AF lens moving device or an OIS lens moving device. Here, the meanings of AF and OIS may be the same as those that were described in the AF camera module and the OIS camera module. 
       FIG. 2  is a cross-sectional view of an embodiment of the camera device  200  shown in  FIG. 1 . In  FIG. 2 , the reference numerals the same as those in  FIG. 1  indicate the same elements. 
     Referring to  FIG. 2 , the lens moving apparatus  100  of the camera device  200  may be an OIS lens moving device. 
     The lens moving apparatus  100  may include a housing  140 , a bobbin  110 , which is disposed in the housing  140  and in which the lens or the lens barrel  400  is mounted, a first coil  120  disposed at the bobbin  110 , a magnet  130  disposed at the housing  140  so as to face the first coil  120 , at least one upper elastic member (not shown) coupled both to the upper portion of the bobbin  110  and to the upper portion of the housing  140 , at least one lower elastic member (not shown) coupled both to the lower portion or the bobbin  110  and to the lower portion of the housing  140 , a second coil  230  disposed under the bobbin  110  (and/or the housing  140 ), a circuit board  250  disposed under the second coil  230 , and a base  210  disposed under the circuit board  250 . 
     The lens moving apparatus  100  may further include a cover member  300 , which is coupled to the base  210  of the lens moving apparatus  100  and which provides in conjunction with the base  210 , a space for accommodating the components of the lens moving apparatus  100 . 
     The lens moving apparatus  100  may further include a support member for conductively connecting the upper elastic member to the circuit board  250  and for supporting the housing  140  with respect to the base  210 . Each of the first coil  120  and the second coil  230  may be conductively connected to the circuit board  250 , and may receive a drive signal (driving current) from the circuit board  250 . 
     For example, the upper elastic member may include a plurality of upper elastic units (for example, upper springs), and the support member may include support members connected to the upper elastic units. The first coil  120  may be conductively connected to the circuit board  250  via the upper elastic units and the support member. The circuit board  250  may include a plurality of terminals, and some of the plurality of terminals may be conductively connected to the first coil  120  and/or the second coil  230 . 
     The bobbin  110  and the lens or the lens barrel  400  coupled to the bobbin  110  may be moved in the optical-axis direction using the electromagnetic force resulting from the interaction between the first coil  120  and the magnet  130 . As a result, the displacement of the bobbin  110  in the optical-axis direction is controlled, thereby realizing AF operation. 
     Furthermore, the housing  140  may be moved in a direction perpendicular to the optical axis using the electromagnetic force resulting from the interaction between the second coil  230  and the magnet  130 , thereby realizing handshake correction or OIS operation. 
     For AF feedback operation, the lens moving apparatus  100  of the camera device  200  may further include a sensing magnet (not shown) disposed at the bobbin  110  and an AF position sensor, for example, a hall sensor (not shown) disposed at the housing  140 . In addition, the lens moving apparatus  100  may further include the circuit board (not shown), which is disposed at the housing and/or the base and on which the AF position sensor is disposed or mounted. In another embodiment, the AF position sensor may be disposed at the bobbin, and the sensing magnet may be disposed at the housing. Furthermore, the lens moving apparatus  100  may further include a balancing magnet disposed at the bobbin  110  so as to correspond to the sensing magnet. 
     The AF position sensor may output an output signal corresponding to the result of detection of a magnetic field of the sensing magnet according to movement of the bobbin  110 . The AF position sensor may be conductively connected to the circuit board  250  via the upper elastic member (or the lower elastic member) and/or the support member. The circuit board  250  may provide a drive signal to the AF position sensor, and the output of the AF position sensor may be transmitted to the circuit board  250 . 
     In another embodiment, the lens moving apparatus  100  may be an AF lens moving device. The AF lens moving device may include a housing, a bobbin disposed in the housing, a coil disposed at the bobbin, a magnet disposed at the housing, at least one elastic member coupled both to the bobbin and to the housing, and a base disposed under the bobbin (and/or the housing). The elastic member may include, for example, the above-described upper and lower elastic members. 
     The coil may be provided with a drive signal (for example, driving current), and the bobbin may be moved in the optical-axis direction using the electromagnetic force resulting from the interaction between the coil and the magnet. In another embodiment, the coil may be disposed at the housing, and the magnet may be disposed at the bobbin. 
     For AF feedback operation, the AF lens moving device may further include a sensing magnet disposed at the bobbin, an AF position sensor (for example, a hall sensor) disposed at the housing, and a circuit board, at which the AF position sensor is disposed and which is disposed or mounted on the housing and/or the base. In another embodiment, the AF position sensor may be disposed at the bobbin, and the sensing magnet may be disposed at the housing. 
     The circuit board may be conductively connected to the coil and the AF position sensor. A drive signal may be provided to the coil and the AF position sensor via the circuit board, and the output of the AF position sensor may be transmitted to the circuit board. 
       FIG. 3  is a plan view showing the circuit board  800  and the image sensor  810 .  FIG. 4A  is a cross-sectional view taken along line A-B in  FIG. 3 .  FIG. 4B  is a cross-sectional view taken along line C-D in  FIG. 3 . 
     Referring to  FIGS. 3, 4A and 4B , the circuit board  800  may have a seating recess  80 , in which the image sensor  810  is disposed or received, and one or more application grooves  26   a   1  and  26   b  for application or injection of a foreign-substance-blocking member. 
     Here, the seating recess  800  may be alternatively referred to as a groove, a cavity or a first groove, and each of the application grooves  26   a   1  and  26   b  may be alternatively referred to as an injection groove, a second groove or a cavity. 
     The seating recess  80  in the circuit board  800  may have a bottom surface  81  and a lateral surface  82 . 
     The seating recess  80  in the circuit board  800  may have various shape, such as a polygonal shape, a circular shape, an elliptical shape or the like, and may have a size (for example, a surface area) larger than the size (for example, the surface area) of the image sensor  810 . For example, the surface area of the bottom surface  81  of the seating recess  80  may be larger than the surface area of the lower surface of the image sensor  810 . 
     The depth H 1  of the seating recess  80  in the circuit board  800  may be equal to the height H 2  of the upper surface of the image sensor  810 , without being limited thereto. Here, the height H 2  of the image sensor  810  may be the distance between the bottom surface  81  of the seating recess  80  and the upper surface of the image sensor  810 . 
     For example, although the height of the upper surface of the circuit board  800  may be equal to the height of the upper surface of the image sensor disposed in the seating recess  80 , the disclosure is not limited thereto. 
     In another embodiment, the depth H 1  of the seating recess  80  in the circuit board  800  may be greater than the height H 2  of the upper surface of the image sensor  810  (H 1 &gt;H 2 ). For example, the height of the upper surface of the circuit board  800  may be greater than the height of the upper surface of the image sensor  810  disposed in the seating recess  80 . 
     In a further embodiment, the depth H 1  of the seating recess  80  in the circuit board  800  may be less than the height H 2  of the upper surface of the image sensor  810  (H 1 &lt;H 2 ). For example, the height of the upper surface of the circuit board  800  may be less than the height of the upper surface of the image sensor  810  disposed in the seating recess  80 . 
     The lateral surface of the image sensor  810  may be spaced apart from the lateral surface  82  of the seating recess  80  in the circuit board  800 . For example, the distance d 1  between the lateral surface of the image sensor  810  and the lateral surface  82  of the seating recess  80  in the circuit board  800  may be 0.1 mm-0.5 mm. For example, the distance d 1  may be 0.1 mm-0.3 mm. 
     If the distance d 1  is less than 0.1 mm, a process margin is insufficient to dispose the image sensor  810  in the seating recess  80  in the circuit board  800 , and the image sensor  810  or the circuit board  800  may be damaged due to a collision between the image sensor  810  and the circuit board  800  caused by external impact. 
     If the distance d 1  is greater than 0.5 mm, the distance between the terminals  41   a  and  41   b  of the circuit board  800  and the terminals  42   a  and  42   b  of the image sensor  810  increases, thereby making it difficult to perform wire bonding and decreasing the reliability of wire bonding. 
     Referring to  FIG. 3 , the lateral surface  82  of the seating recess  80  in the circuit board  800  may have a first lateral surface  21   a  and a second lateral surface  21   b , which face each other, and a third lateral surface  21   c  and a fourth lateral surface  21   d , which face each other. For example, the third lateral surface  21   c  may connect the first end of the first lateral surface  21   a  and the first end of the second lateral surface  21   b  to each other, and the fourth lateral surface  21   d  may connect the second end of the first lateral surface  21   a  and the second end of the second lateral surface  21   b  to each other. 
     The application grooves  26   a   1  and  26   b  in the circuit board  800  may be provided in at least one of the first lateral surface  21   a  and the second lateral surface  21   b  of the seating recess  80 . 
     The application grooves  26   a   1  and  26   b  may be depressed into the first lateral surface  21   a  (or the second lateral surface  21   b ) of the seating recess  80  in a horizontal direction and may have openings formed in the upper surface of the circuit board  800 . The application grooves  26   a   1  and  26   b  may serve as introduction inlets through which the foreign-substance-blocking member  310  is injected or applied. 
     For example, the horizontal direction may be a direction toward the first lateral surface  21   a  (or the second lateral surface  21   b ) of the seating recess  80  from the first lateral surface of the image sensor  810 . The first lateral surface of the image sensor  810  may be the lateral surface that faces the first lateral surface  21   a  (or the second lateral surface  21   b ) of the seating recess  80 . 
     For example, the corner at which two adjacent lateral surfaces of the seating recess  80  meet each other may have a curved shape or a round shape, without being limited thereto. In another embodiment, the corner at which two adjacent lateral surfaces of the seating recess  80  meet each other may have an angled shape. For example, two adjacent lateral surfaces of the seating recess  80  may be perpendicular to each other. 
     Each of the first lateral surface  21   a  and the second lateral surface  21   b  of the seating recess  80  may have a length greater than that of each of the third lateral surface  21   c  and the fourth lateral surface  21   d  of the seating recess  80 . For example, each of the third lateral surface  21   c  and the fourth lateral surface  21   d  of the seating recess  80  may be a shorter lateral surface, and each of the first lateral surface  21   a  and the second lateral surface  21   b  may be a longer lateral surface, which is longer than the shorter lateral surface. In another embodiment, each of the first lateral surface  21   a  and the second lateral surface  21   b  of the seating recess  80  may be a shorter lateral surface, and each of the third lateral surface and the fourth lateral surface may be a longer lateral surface, which is longer than the shorter lateral surface. 
     For example, since the application grooves  26   a   1  and  26   b  are provided in the first lateral surface  21   a  and the second lateral surface  21   b  of the seating recess  80 , which are the longer lateral surfaces, it is possible to ensure sufficient space to inject the foreign-substance-blocking member and to uniformly diffuse the foreign-substance-blocking member into the seating recess  80 . 
     For example, the circuit board  800  may have the first application groove  26   a   1 , formed in the first lateral surface  21   a  of the seating recess  80 , and the second application groove  26   b , formed in the second lateral surface  21   b  of the seating recess  80 . 
     For example, the first application groove  26   a   1  and the second application groove  26   b  may face or overlap each other in a horizontal direction, without being limited thereto. In another embodiment, the first application groove  26   a   1  and the second application groove  26   b  may not face or overlap each other in a horizontal direction. 
     For example, the first application groove  26   a   1  may be formed in the center or the central location of the first lateral surface  21   a  of the seating recess  80 . For example, the center of the first application groove  26   a   1  may be aligned with the center or the central location of the first lateral surface  21   a.    
     Furthermore, the second application groove  26   b  may be formed in the center or the central location of the second lateral surface of the seating recess  80 . For example, the center of the second application groove  26   b  may be aligned with the center or the central location of the second lateral surface  21   b . Here, the center of each of the application grooves  26   a   1  and  26   b  may be the central point between two ends of each of the lateral surfaces  21   a  and  21   b.    
     The reason for this is to allow the foreign-substance-blocking member, which is injected through the first application groove  26   a   1 , to be uniformly moved into the space between the lateral surface of the image sensor  810  disposed in the seating recess  800  and the lateral surface  82  of the seating recess  80  along the first lateral surface  21   a.    
     In  FIG. 3 , although one application groove is formed in one of the lateral surfaces (for example,  21   a  or  21   b ) of the seating recess  80 , the disclosure is not limited thereto. Two or more application grooves, which are spaced apart from each other, may be formed in one of the lateral surfaces (for example,  21   a  or  21   b ) of the seating recess  80 . 
     Although the inner surface of each of the application grooves  26   a   1  and  26   b  may be curved, the disclosure is not limited thereto. In another embodiment, the inner surface of the application groove may include at least one flat surface and/or at least one curved surface. 
     For example, although the bottom surfaces of the application grooves  26   a   1  and  26   b  may be flush with the bottom surface of the seating recess  80 , the disclosure is not limited thereto. 
     The maximum distance d 2  between an imaginary straight line  1401  between the two ends of each of the application grooves  26   a   1  and  26   b  and the inner surface of each of the inner surfaces  22   a  and  22   b  of the application groove  26   a   1  may be 0.1 mm-2.5 mm. For example, the distance d 2  may be 0.25 mm-1 mm. 
     For example, the distance d 2  may be half the diameter R of each of the application grooves  26   a   1  and  26   b , without being limited thereto. 
       FIG. 4C  illustrates application grooves  26   a   11  and  26   b   1  according to another embodiment.  FIG. 4C  is a cross-sectional view taken along line C-D in  FIG. 4B . 
     Reference numerals that are the same as those in  FIG. 4B  indicate the same elements, and description of the same elements will be given briefly or omitted. 
     Referring to  FIG. 4C , each of the bottom surface  22   c   1  of the first application groove  26   a   11  and the bottom surface  22   c   2  of the second application groove  26   b   1  may have a height difference ST in the optical-axis direction or in a direction toward the upper surface from the lower surface of the circuit board  800 . 
     For example, each of the bottom surface  22   c   1  of the first application groove  26   a   11  and the bottom surface  22   c   2  of the second application groove  26   b   1  may be positioned higher than the bottom surface  81  of the seating recess  80 . Furthermore, each of the bottom surface  22   c   1  of the first application groove  26   a   11  and the bottom surface  22   c   2  of the second application groove  26   b   1  may be positioned lower than the upper surface of the image sensor  810 . 
     In  FIG. 3 , although each of the first and second application grooves  26   a   1  and  26   b  may have a semicircular shape when viewed from above, the disclosure is not limited thereto. In another embodiment, each of the first and second application grooves may have a semi-elliptical shape or a polygonal shape (for example, a triangular shape, a quadrilateral shape, or the like) when viewed from above. 
     The diameter R of each of the first and second application grooves  26   a   1  and  26   b  may be 0.2 mm-5 mm. For example, the diameter R may be 0.5 mm-2 mm. 
     If the diameter R is less than 0.2 mm, the diameter of each of the application grooves  26   a   1  and  26   b  is less than that of an injection port (for example, an injection needle) of an injection device for injection of the foreign-substance-blocking member  310 , thereby making it difficult to inject the foreign-substance-blocking member or causing overflow of the foreign-substance-blocking member. 
     If the diameter R is greater than 5 mm, because a large amount of foreign-substance-blocking member must be injected into the application grooves in order to introduce the foreign-substance-blocking member into the seating recess  80 , consumption of the foreign-substance-blocking member may increase, and the foreign-substance-blocking member that is injected into the application grooves may not be easily moved into the seating recess. 
     For example, the diameter R of each of the application grooves  26   a   1  and  26   b  may be greater than the distance d 1  between the lateral surface  82  of the seating recess  80  and the lateral surface of the image sensor  810  disposed in the seating recess  80 . 
     The ratio (d 1 :R) of the distance d 1  between the lateral surface of the image sensor  810  and the lateral surface  82  of the seating recess  80  to the diameter R of each of the first and second application grooves  26   a   1  and  26   b  may be 1:1.7-1:20. For example, the ratio (d 1 :R) may be 1:2-1:10. If the ratio (R/d 1 ) is less than 1.7, the foreign-substance-blocking member is not easily injected, or the foreign-substance-blocking member may overflows. If the ratio (R/d 1 ) is greater than 20, consumption of the foreign-substance-blocking member may be needlessly high, and the foreign-substance-blocking member that is injected into the application grooves may not easily move into the seating recess. 
     The foreign-substance-blocking member  310  may be disposed in the application grooves  26   a   1  and  26   b  and in the space between the lateral surface of the image sensor  810  and the lateral surface  82  of the seating recess  80  in the circuit board  800 . 
     For example, the foreign-substance-blocking member  310  may be disposed on the lateral surfaces and the bottom surfaces of the application grooves  26   a   1  and  26   b . For example, the foreign-substance-blocking member  310  may be disposed on the lateral surface of the seating recess  80  and on a first area of the bottom surface  81  of the seating recess  80 . Here, the first area of the bottom surface  81  of the seating recess  80  may be the area between the lateral surface of the image sensor  810  and the lateral surface  82  of the seating recess  80 . 
     Here, the foreign-substance-blocking member  310  may be interchangeably used with a foreign-substance-blocking member, an adhesive member, a protective member, an insulative member (or a coating agent), a resin body, or epoxy. 
     For example, the foreign-substance-blocking member  310  may be made of resin or plastic. 
     For example, the foreign-substance-blocking member  310  may be made of thermohardening resin, naturally hardening resin or UV hardening resin. 
     For example, the foreign-substance-blocking member  310  may include thermohardening epoxy, UV hardening epoxy or a mixture of thermohardening epoxy and UV hardening epoxy. Furthermore, the foreign-substance-blocking member  310  may be epoxy including titanium (Ti). 
     For example, the foreign-substance-blocking member  310  may include a first epoxy disposed in the seating recess  80 , and at least a portion of the first epoxy of the foreign-substance-blocking member  310  may be disposed in at least one of the application grooves  26   a   1  and  26   b . Another portion of the first epoxy of the foreign-substance-blocking member  310  may be disposed between the first to fourth lateral surfaces of the seating recess  80  and the lateral surface of the image sensor  810  disposed in the seating recess  80 . 
     Furthermore, the foreign-substance-blocking member  310  may further include a second epoxy, which is disposed between the bottom surface  81  of the seating recess  800  and the lower surface of the image sensor  810  so as to attach the bottom surface  81  of the seating recess  800  and the lower surface of the image sensor  810  to each other. For example, the first epoxy and the second epoxy may be made of the same epoxy material. 
     The upper surface of the foreign-substance-blocking member  310 , which is disposed in the application grooves  26   a   1  and  26   b  and in the seating recess  80 , may be positioned lower than the upper surface of the image sensor  810 . The reason for this is to prevent the foreign-substance-blocking member  310  from overflowing onto the upper surface of the image sensor  810  and thus contaminating the terminals  42   a  and  42   b  of the image sensor  810 . 
     The upper surface of the foreign-substance-blocking member  310 , which is disposed in the application grooves  26   a   1  and  26   b  and the seating recess  80 , may be positioned lower than the upper surface of the circuit board  800 . The reason for this is to prevent the foreign-substance-blocking member  310  from overflowing onto the upper surface of the circuit board  800  and thus contaminating the terminals  41   a  and  41   b  of the circuit board  800 . 
     In another embodiment, the upper surface of the foreign-substance-blocking member  310 , which is disposed in the application grooves  26   a   1  and  26   b  and in the seating recess  80 , may be flush with the upper surface of the image sensor  810  and/or the upper surface of the circuit board  800 . 
     In a further embodiment, the upper surface of the foreign-substance-blocking member  310  disposed in the application grooves  26   a   1  and  26   b  may be positioned higher than the upper surface of the image sensor  810  and/or the upper surface of the circuit board  800 . The reason for this is because there is no concern of the terminals  41   a ,  41   b ,  42   a  and  42   b  being contaminated even when the foreign-substance-blocking member  310  overflows onto the upper surface of the circuit board  800  around the application grooves  26   a   1  and  26   b  because the application grooves  26   a   1  and  26   b  are positioned so as to be spaced apart from the terminals  42   a  and  42   b  of the image sensor  810  and the terminals  41   a  and  41   b  of the circuit board  800 . 
     The camera device  200  may further include the wires  51   a  and  51   b , which conductively connect the terminals  41   a  and  41   b  provided at the circuit board  800  to the terminals  42   a  and  42   b  provided at the image sensor  810 . 
     The circuit board  800  may include at least one first terminal  41   a , which is disposed in an area adjacent to the third lateral surface  21   c  of the seating recess  80 . 
     For example, the at least one first terminal  41   a  may include a plurality of first terminals, and the plurality of first terminals  41   a  may be arranged so as to be spaced apart from each other in a direction toward the second lateral surface  21   b  from the first lateral surface  21   a  of the seating recess  80 . 
     Furthermore, the circuit board  800  may include at least one second terminal  41   a , which is disposed in another area adjacent to the fourth lateral surface  21   d  of the seating recess  80 . 
     For example, the at least one second terminal  41   b  may include a plurality of second terminals, and the plurality of second terminals  41   b  may be arranged so as to be spaced apart from each other in a direction toward the second lateral surface  21   b  from the first lateral surface  21   a  of the seating recess  80 . 
     For example, the first terminal  41   a  and the second terminal  41   b  of the circuit board  800  may be disposed so as to face each other in a direction toward the fourth lateral surface  21   d  from the third lateral surface  21   c  of the seating recess  80 , without being limited thereto. 
     The image sensor  810  may include the first and second terminals  42   a  and  42   b , which are conductively connected to the first and second terminals  41   a  and  41   b  of the circuit board  800 . 
     The first terminal  42   a  of the image sensor  810  may be disposed in a first area on the upper surface of the image sensor  810  adjacent to the lateral surface of the image sensor  810  that faces the third lateral surface of the seating recess  80 . 
     For example, the first terminal  42   a  of the image sensor  810  may include a plurality of first terminals, and the plurality of first terminals  42   a  of the image sensor  810  may be arranged so as to be spaced apart from each other in a direction toward the second lateral surface  21   b  from the first lateral surface  21   a  of the seating recess  80  in the circuit board  800 . 
     The second terminal  42   b  of the image sensor  810  may be disposed in a second area on the upper surface of the image sensor  810  adjacent to the lateral surface of the image sensor  810  that faces the fourth lateral surface of the seating recess  80 . 
     For example, the second terminal  42   b  of the image sensor  810  may include a plurality of second terminals, and the plurality of second terminals  42   b  of the image sensor  810  may be arranged so as to be spaced apart from each other in a direction toward the second lateral surface  21   b  from the first lateral surface  21   a  of the seating recess  80  in the circuit board  800 . 
     The first wire  51   a  may connect the first terminal  41   a  of the circuit board  800  to the first terminal  42   a  of the image sensor  810  via solder or a conductive member. 
     The second wire  51   b  may connect the second terminal  41   b  of the circuit board  800  to the second terminal  42   b  of the image sensor  810  via solder or a conductive member. 
     The first and second wires  51   a  and  51   b  may overlap the third lateral surface  21   c  and the fourth lateral surface  21   d  of the seating recess  80  but may not overlap the first and second application grooves  21   a  and  21   b  in the optical-axis direction. 
     The circuit board  800  having the application grooves  26   a   1  and  26   b  and the seating recess  80  is prepared. For example, the application grooves  26   a   1  and  26   b  may be formed through a cutting process using a cutter. 
     An operation of mounting the image sensor  810  to the circuit board  800  to an operation of forming the foreign-substance-blocking member  310  may be performed as follows. 
     The image sensor  810  is mounted on the circuit board  800 . 
     Subsequently, wire bonding is performed between the terminals  41   a  and  41   b  of the circuit board  800  and the terminals  42   a  and  42   b  of the image sensor  810 . 
     Subsequently, a material for formation of the foreign-substance-blocking member is injected or applied into the application grooves  26   a   1  and  26   b . By applying epoxy having good fluidity, foreign substances present in the space between the image sensor  810  and the lateral surface  82  of the seating recess  80  are fixed, and introduction of new foreign substances into the space between the image sensor  810  and the lateral surface  82  of the seating recess  80  is prevented, thereby preventing deterioration in reliability of the image sensor  810  due to foreign substances. 
     Subsequently, the injected or applied foreign-substance-blocking member material is cured so as to form the foreign-substance-blocking member, and then a packaging process is performed. 
     A gap of 0.1 mm-0.3 mm is present between the lateral surface of the seating recess in the circuit board and the lateral surface of the image sensor disposed in the seating recess. Hence, when foreign substances enter the space between the lateral surface of the seating recess in the circuit board and the lateral surface of the image sensor disposed in the seating recess, it is difficult to remove the foreign substances due to the wire that conductively connects the circuit board to the image sensor. Furthermore, the foreign substances may escape from the space and may thus cause a malfunction after the packaging process. 
     When epoxy is merely applied into the space in order to prevent such malfunction due to foreign substances, it is difficult to apply the epoxy because the gap between the lateral surface of the seating recess in the circuit board and the lateral surface of the image sensor disposed in the seating recess is narrow. Meanwhile, when the width of the gap between the lateral surface of the seating recess and the lateral surface of the image sensor is increased in order to facilitate application of epoxy, the length of the wire may be increased, thereby deteriorating the reliability of wire bonding. 
     Since the embodiment is additionally provided with the application grooves  26   a   1  and  26   b  for application of a foreign-substance-blocking member (made of, for example, epoxy) to the lateral surface  82  of the seating recess  80 , it is possible to facilitate application of the foreign-substance-blocking member into the space between the lateral surface  82  of the seating recess  80  and the lateral surface of the image sensor  810 , and it is possible to perform the operation of applying the foreign-substance-blocking member after the operation of performing the wire bonding between the circuit board  800  and the image sensor  810 . 
     Furthermore, since the embodiment does not need to increase the distance between the lateral surface  82  of the seating recess  80  and the lateral surface of the image sensor  810 , there is no need to increase the length of the wire due to the increase in the distance, thereby preventing deterioration in reliability of wire bonding. 
     In addition, since the embodiment is able to apply the foreign-substance-blocking member after the operation of performing wire bonding between the circuit board  800  and the image sensor  810 , there is no considerable influence on reliability in wire bonding even when the terminals  41   a  and  41   b  of the circuit board  800  and the terminals  42   a  and  52   b  of the image sensor  810  are contaminated by the foreign-substance-blocking member. 
       FIG. 5A  illustrates a modification of the application grooves shown in  FIG. 3 . 
     Referring to  FIG. 5A , the first application groove  26   a   1  and the second application groove  26   b  may not face each other in a direction toward the second lateral surface from the first lateral surface of the seating recess  80 . 
     For example, the first application groove  26   a   1  may be positioned between the center of the first lateral surface  21   a  of the seating recess  80  and the first corner, at which the first lateral surface  21   a  and the fourth lateral surface  21   c  meet each other. 
     For example, the second application groove  21   b  may be positioned between the center of the second lateral surface  21   b  of the seating recess  80  and the second corner, at which the second lateral surface  21   b  and the third lateral surface  21   d  meet each other. The first corner and the second corner of the seating recess  80  may face each other. 
     For example, the first and second application grooves  26   a   1  and  26   b  may be positioned opposite each other with respect to the central line, which is connected both to the center of the first lateral surface  21   a  and to the center of the second lateral surface  21   b.    
       FIG. 5B  is a plan view of the image sensor  810  disposed in a circuit board  800   a  according to another embodiment. 
     Referring to  FIG. 5B , the circuit board  800   a  according to another embodiment may have the seating recess  80  and application grooves  26   a   2  and  26   b   2 . 
     The application grooves  26   a   2  and  26   b   2  shown in  FIG. 5B  may be formed in the first and second lateral surfaces  21   a  and  21   b  of the seating recess  80  in the circuit board  800   a.    
     The first application groove  26   a   2  (or the second application groove  26   b   2 ) may include a first portion  106   a  abutting on the first lateral surface  21   a  (or the second lateral surface  21   b ) and a second portion  105   b  connected to the first portion  106   a.    
     The second portion  106   b , in which the foreign-substance-blocking member  310  is injected or applied, may be spaced apart from the first lateral surface  21   a  (or the second lateral surface  21   b ) of the seating groove  80 . 
     The distance K between the first lateral surface  21   a  (or the second lateral surface  21   b ) of the first application groove  26   a   2  (or the second application groove  26   b   2 ) may be smaller than the distance between the lateral surface  82  of the seating recess  80  and the lateral surface of the image sensor  810 , without being limited thereto. 
     The first portion  106   a  may have a linear shape, and the second portion  106   b  may have a circular shape, an elliptical shape, a semicircular shape, or a polygonal shape, without being limited thereto. 
     The diameter (M or the horizontal length) of the first portion  106   a  may be less than the diameter R of the second portion  106   b . Although the diameter R of the second portion  106   b  may be equal to the diameter of each of the above-described application grooves  26   a   1  and  26   b , the disclosure is not limited thereto. 
     Since the diameter R of the second portion  106   b  is greater than the diameter M of the first portion  106   a , the embodiment is able to suppress overflow of the foreign-substance-blocking member  310  onto the upper surface of the circuit board  800   a  during injection of the foreign-substance-blocking member  310 . 
     Furthermore, since the second portion  106   b , into which the foreign-substance-blocking member  310  is injected, is spaced apart from the lateral surface  82  of the seating recess  80 , the foreign-substance-blocking member  310  injected in the second portion  106   b  may slowly flow into the space between the lateral surface  82  of the seating recess  80  and the lateral surface of the image sensor  810  through the first portion  106   a , thereby preventing the foreign-substance-blocking member  310  from overflowing onto the upper surface of the image sensor  810  or from adhering to the wires  51   a  and  51   b.    
     The application grooves  26   a   2  and  26   b  shown in  FIG. 5B  are different from the application grooves  26   a   1  and  26   b  shown in  FIG. 3  only in shape. Accordingly, the description of the disposition, the height difference, the size, and the like of the application grooves  26   a   1  and  26   b  shown in  FIGS. 3, 4A, 4B and 4C  may be identically or similarly applied to the application grooves  26   a   2  and  26   b   2  shown in  FIG. 5B . 
       FIG. 6  is a perspective view of a camera device  200 - 1  according to another embodiment.  FIG. 7  is a cross-sectional view showing the circuit board  800   b , the image sensor  810 , the foreign-substance-blocking member  310  and the reinforcing member  900  shown in  FIG. 6 . 
     Referring to  FIGS. 6 and 7 , the camera device  200 - 1  may include the lens or the lens barrel  400 , the lens moving apparatus  100 , the filter  610 , the holder  600 , the circuit board  800   b , the image sensor  810 , the foreign-substance-blocking member  310  and the reinforcing member  900 . Although wires for conductively connecting the image sensor  810  to the circuit board  800   b  are omitted in  FIG. 6 , the description of the above-described wires  51   a  and  51   b  may be applied to the embodiment shown in  FIG. 6 . 
     The circuit board  800  shown in  FIG. 1  has the seating recess  80  for seating the image sensor  810  therein, whereas the circuit board  800   b  shown in  FIG. 6  has a bore  801 , in which the image sensor  810  is disposed, and the image sensor  810  is disposed on the reinforcing member  900 . 
     The circuit board  800   b  may have the bore  801  corresponding to the bore  501  in the holder  600 . 
     The bore  801  in the circuit board  800  may be a through hole, which is formed through the circuit board  800   b  in the optical-axis direction. The shape of the bore  801  in the circuit board  800  may be identical to the shape of the seating recess shown in  FIG. 1  when viewed from above. 
     For example, the bore  801  in the circuit board  800   b  may have a structure that is identical to a structure in which the bottom surface  81  is omitted from the seating recess  80  shown in  FIG. 1 , or in which a bore is formed in the bottom surface  81  shown in  FIG. 1 . Accordingly, the description of the seating recess  80  shown in  FIG. 1  may also be applied, except for the bottom surface  81  shown in  FIG. 1 . 
     The circuit board  800   b  may have one or more application grooves  26   a   2  and  26   b   2  formed in the lateral surface of the bore  801  for application or injection of the foreign-substance-blocking member  310 . 
     The one or more application grooves  26   a   2  and  26   b   2  may be depressed from the first lateral surface  21   a  (or the second lateral surface  21   b ) of the bore  801  in a horizontal direction. 
     The difference between the application grooves  26   a  and  26   b  shown in  FIG. 1  and the application grooves  26   a   2  and  26   b   2  shown in  FIG. 6  is that the application grooves  26   a   2  and  26   b   2  shown in  FIG. 6  are through holes, which are formed through the upper and lower surfaces of the circuit board  800   b.    
     The description of the lateral surfaces  21   a  to  21   d  of the seating recess  80  may be applied to the lateral surface of the bore  801 . One or more application grooves  26   a   2  and  26   b   2  may be formed in at least one of the first lateral surface  21   a  and the second lateral surface  21   b  of the bore  801  in the circuit board  800   b.    
     For example, the bore  801  in the circuit board  800   b  may be alternatively referred to as a seating hole, and the application grooves  26   a   2  and  26   b   2  may be alternatively referred to as application holes. 
     Hereinafter, the bore  801  will be referred to as a seating hole, and the application grooves  26   a   2  and  26   b   2  will be referred to as application holes. 
     The description of the application grooves  26   a   2  and  26   b   2  shown in  FIGS. 1 to 4C  may be applied to the application holes  26   a   2  and  26   b   2  shown in  FIG. 6 . For example, the description regarding the shape, the size and the like of the application grooves  26   a    26   b  may be applied to the application holes  26   a   2  and  26   b   2 . 
     The foreign-substance-blocking member  310  may be disposed in the space between the lateral surface of the image sensor  810  and the seating hole  801  in the circuit board  800   b.    
     For example, the foreign-substance-blocking member  310  may be disposed on the lateral surfaces of the application holes  26   a   2  and  26   b   2 , the lateral surface of the seating hole  801  (for example, the first to fourth lateral surfaces), and the first area of the reinforcing member  900 . 
     Here, the description of the first to fourth lateral surfaces  21   a  to  21   d  of the seating recess  80  may be applied to the lateral surfaces (for example, the first to fourth lateral surfaces) of the seating hole  801 . 
     For example, the first area of the reinforcing member  900  may be the area on the upper surface of the reinforcing member  900  that is positioned between the lateral surface of the image sensor  810  and the lateral surface (for example, the first to fourth lateral surfaces) of the seating hole  801  in the circuit board  800   b . For example, the first area of the reinforcing member  900  may be the area on the upper surface of the reinforcing member  900  that is exposed through the application grooves  26   a   2  and  26   b   2  and the seating hole  801 . 
     The image sensor  810  may be disposed in the seating hole  810  in the circuit board  800   b . Furthermore, the image sensor  810  may be disposed on the reinforcing member  900 . 
     The reinforcing member  800  may be disposed under the circuit board  800   b.    
     The upper surface of the reinforcing member  900  may include an area (hereinafter, referred to as a mounting area) that corresponds to the bore  801  in the circuit board  800   b  and on which the image sensor  810  is mounted. 
     An adhesive member (for example, epoxy) may be disposed between the lower surface of the circuit board  800   b  and the upper surface of the reinforcing member  900 , and the circuit board  800   b  may be attached or secured to the reinforcing member  900  by means of the adhesive member. 
     An adhesive member (for example, epoxy) may be disposed between the lower surface of the image sensor  810  and the upper surface (for example, the mounting area) of the reinforcing member  900 , and the image sensor  810  may be attached or secured to the reinforcing member  900  by means of the adhesive member. Although the adhesive member may be made of, for example, epoxy, thermohardening adhesive, UV hardening adhesive, adhesive film or the like, the disclosure is not limited thereto. 
     For example, the foreign-substance-blocking member  310  may include first epoxy disposed in the seating hole  801 , and at least a portion of the first epoxy may be disposed in the application holes  26   a   2  and  26   b   2 . 
     The image sensor  810  disposed on the upper surface of the reinforcing member  800  may be conductively connected to the circuit board  800   b  via the wires  51   a  and  51   b.    
     The reinforcing member  800 , which is a plate-shaped member having a predetermined thickness and hardness, is capable of stably supporting the image sensor  810  and of suppressing breakage of the image sensor due to external impact or contact. 
     Furthermore, the reinforcing member  800  is capable of improving a radiation effect of dissipating the heat generated by the image sensor  810  outwards. 
     For example, the reinforcing member  900  may be made of a metal material having high heat conductivity, such as stainless steel or aluminum, without being limited thereto. In another embodiment, the reinforcing member  900  may be made of glass epoxy, plastic, synthetic resin or the like. 
     The reinforcing member  900  may be conductively connected to the ground terminal of the circuit board  800   b  so as to serve as a ground for ensuring ESD (Electrostatic Discharge Protection) for the camera device. 
       FIG. 8  is an exploded perspective view of an embodiment of the lens moving apparatus  100 .  FIG. 9  is an assembled perspective view of the lens moving apparatus  100  from which the cover member  300  shown in  FIG. 8  is removed. For example, the lens moving apparatus  100  shown in  FIG. 8  may be an embodiment of the lens moving apparatus shown in  FIG. 2 . 
     Referring to  FIGS. 8 and 9 , the lens moving apparatus  100  may include a bobbin  110 , a first coil  120 , a first magnet  130 , a housing  140 , an upper elastic member  150 , a lower elastic member  160  and a second coil  230 . 
     The lens moving apparatus  100  may further include a first position sensor  170  and a second magnet  180  for AF feedback operation. 
     In addition, the lens moving apparatus  100  may further include second position sensors  240  ( 240   a  and  240   b ) for OIS (Optical Image Stabilizer) feedback operation. 
     Furthermore, the lens moving apparatus  100  may further include at least one of a third magnet  185 , a circuit board  190 , a support member  220 , a circuit board  250 , a base  210  and a cover member  300 . 
     Hereinafter, the term “coil” may be interchangeably used with “coil unit”, and the term “elastic member” may be interchangeably used with “elastic unit” or “spring”. 
     First, the bobbin  110  will be described. 
     The bobbin  110  may be disposed in the housing  140  and may be moved in the direction of the optical axis OA or in the first direction (for example, in the z-axis direction) by the electromagnetic interaction between the first coil  120  and the first magnet  130 . 
       FIG. 10  is a perspective view illustrating the bobbin  110 , the first coil  120 , the second magnet  180 , and the third magnet  185  shown in  FIG. 8 . 
     Referring to  FIG. 10 , the bobbin  110  may have a bore or a cavity in which the lens or the lens barrel is mounted. For example, the bore in the bobbin  110  may be a through hole, which is formed through the bobbin  110  in the optical-axis direction. Although the bore in the bobbin  110  may have a circular shape, an elliptical shape or a polygonal shape, the disclosure is not limited thereto. 
     The lens may be directly mounted in the bore in the bobbin  110 , without being limited thereto. In another embodiment, the lens barrel to which at least one lens is mounted or coupled may be coupled or mounted in the bore in the bobbin  110 . The lens or the lens barrel may be coupled to the inner circumferential surface  110   a  of the bobbin  110  in various ways. 
     The bobbin  110  may include first side portions  110   b - 1 , which are spaced apart from each other, and second side portions  110   b - 2 , which are spaced apart from each other. Each of the second side portions  110 - 2  may connect two adjacent first side portions to each other. For example, the length of each of the first side portions  110   b - 1  of the bobbin  110  in a horizontal direction or in a transverse direction may be different from the length of each of the second side portions  110   b - 2  in a horizontal direction or in a transverse direction, without being limited thereto. 
     Furthermore, the bobbin  110  may be provided on the outer surface thereof with a projection  112 , which projects in the second direction and/or in the third direction. The projection  112  of the bobbin  110  may serve to prevent the bobbin  110  from directly colliding with the housing  140  even when the bobbin  110  is moved beyond a prescribed range due to an external impact or the like during movement of the bobbin  110  in the optical-axis direction for autofocusing. Furthermore, the projection  112  of the bobbin  110  may serve as a stopper in conjunction with a groove portion  146  in the housing  140 . 
     The bobbin  110  may be provided in the upper surface thereof with a first escape groove  112   a  for avoiding interference with a first frame connector  153  of the upper elastic member  150 . For example, the first escape groove  112   a  may be formed in the first side portion  110   b - 1  of the bobbin  110 , without being limited thereto. 
     The bobbin  110  may be provided on the upper surface thereof with a guide portion  111  for guiding the mounting position of the upper elastic member  150 . For example, the guide portion  111  of the bobbin  110  may project from the upper surface of the bobbin  110  in the first direction (for example, in the z-axis direction) so as to guide the path along which the frame connector  153  of the upper elastic member  150  is moved, as illustrated in  FIG. 10 . For example, the guide portion  111  may be disposed in the escape groove  112   a.    
     The bobbin  110  may include a first coupler  113   a  or an upper support protrusion, which is coupled and secured to the upper elastic member  150 . Although the first coupler  113   a  of the bobbin  110  may have a protrusion shape, the disclosure is not limited thereto. In another embodiment, the first coupler  113   a  may be a groove or a flat surface. 
     The bobbin  110  may include a second coupler (not shown), which is coupled and secured and secured to the lower elastic member  160 . Although the second coupler may have a protrusion shape, the disclosure is not limited thereto. In another embodiment, the second coupler of the bobbin  110  may be a groove or a flat surface. 
     The bobbin  110  may include a stopper  116 , which projects from the upper surface thereof upwards. 
     The stopper  116  of the bobbin  110  may serve to prevent the upper surface of the bobbin  110  from directly colliding with the inner side of the upper plate of the cover member  300  even when the bobbin  110  is moved beyond a prescribed range due to an external impact or the like during movement of the bobbin  110  in the first direction for autofocusing. 
     The bobbin  110  may be provided in the outer surface thereof with a coil-seating groove, in which the first coil  120  is seated, fitted or disposed. The coil-seating groove may have a groove structure depressed from the outer surface  110   b  of the first and second side portions  110   b - 1  and  110   b - 2 , and may have a shape that coincides with the shape of the first coil  120 , for example a closed curve shape (for example, a ring shape). 
     The bobbin  110  may have a second magnet-seating groove  180   a  formed in the outer surface  110   b , in which the second magnet  180  is seated, fitted, secured or disposed. 
     The second magnet-seating groove  180   a  in the bobbin  110  may be depressed from the outer surface  110   b  of the bobbin  110 , and may have an opening, which is formed in the upper surface of the bobbin  110 , without being limited thereto. 
     The second magnet-seating groove  180   a  in the bobbin  110  may be positioned above the coil-seating groove, in which the first coil  120  is disposed, and may be spaced apart from the coil-seating groove, without being limited thereto. 
     Furthermore, the bobbin  110  may have a third magnet-seating groove  185   a  formed in the upper surface thereof, in which the third magnet  185  is seated, fitted, secured, or disposed. 
     The third magnet-seating groove  185   a  may be depressed from the outer surface  110   b  of the bobbin  110 , and may have an opening that is formed in the upper surface of the bobbin  110 , without being limited thereto. 
     The third magnet-seating groove  185   a  in the bobbin  110  may be positioned above the coil-seating groove, in which the first coil  120  is disposed, and may be spaced apart from the coil-seating groove, without being limited thereto. 
     The second magnet-seating groove  180   a  may be formed in one of the second side portions  110   b - 2  of the bobbin  110 , and the third magnet-seating groove  185   a  may be formed in another of the second side portions  110   b - 2  of the bobbin  110 . 
     The third magnet-seating groove  185   a  may be positioned so as to face the second magnet-seating groove  180   a . For example, the second and third magnet-seating grooves  180   a  and  185   a  may be formed in two second side portions of the bobbin  110  that face each other. 
     Since the second magnet  180  and the third magnet  185  are disposed or arranged at the bobbin in a balanced state with respect to the first position sensor  170 , weight equilibrium between the second magnet  180  and the third magnet  185  may be established, and the influence of the magnetic force of the first magnet  130  and the second magnet  180  on the first coil  120  may cancel each other, thereby improving the accuracy of an AF (Autofocusing) operation. 
     Next, the first coil  120  will be described. 
     The first coil  120  may be disposed on the outer surface  110   b  of the bobbin  110 . 
     Although the first coil  120  may be disposed under the second and third magnets  180  and  185 , the disclosure is not limited thereto. For example, although the first coil  120  may be disposed under the projection  112  of the bobbin  110 , the disclosure is not limited thereto. 
     For example, although the first coil  120  may not overlap the second and third magnets  180  and  185  in the second or third direction, the disclosure is not limited thereto. 
     For example, the first coil  130  may be disposed in the coil-seating groove, the second magnet  180  may be fitted or disposed in the second magnet-seating groove  180   a , and the third magnet  185  may be fitted or disposed in the third magnet-seating groove  185   a.    
     Although each of the second magnet  180  and the third magnet  185 , which are disposed at the bobbin  110 , may be spaced apart from the first coil  120 , the disclosure is not limited thereto. In another embodiment, each of the second magnet  180  and the third magnet  185 , which are disposed at the bobbin  110 , may be in contact with the first coil  120 , or may overlap the first coil  120  in the second or third direction. 
     The first coil  120  may have a closed curve shape, for example a ring shape, which surrounds the outer surface  110   b  of the bobbin  110  in a direction of rotation about the optical axis OA. 
     Although the first coil  120  may be directly wound around the outer surface  110   b  of the bobbin  110 , the disclosure is not limited thereto. In another embodiment, the first coil  120  may be embodied as a coil ring, which is wound around the bobbin  110 , or may be embodied as a coil block having an angled ring shape. 
     Power or a drive signal may be provided to the first coil  120 . The power or the drive signal, which is provided to the first coil  120 , may be a DC signal, an AC signal or a combined DC and AC signal, and may be a voltage-type signal or a current-type signal. 
     When power or a drive signal (for example, drive current) is supplied to the first coil  120 , an electromagnetic force may be created by the electromagnetic interaction between the first coil  120  and the first magnet  130 , and thus the bobbin  110  may be moved in the direction of the optical axis OA by the created electromagnetic force. 
     At the initial position of the AF operation unit, the first coil  120  may be disposed so as to correspond to or overlap the first magnet  130  disposed at the housing  140  in a direction parallel to a line which is perpendicular to the optical axis OA and extends through the optical axis. 
     For example, the AF operation unit may include the bobbin  110  and the components (for example, the first coil  120 , the second magnet  180  and the third magnet  185 ) coupled to the bobbin  110 . 
     The initial position of the AF operation unit may be the initial position of the AF operation unit in the state in which power is not applied to the first coil  1120 , or may be the position of the AF operation unit when the upper and lower elastic members  150  and  160  are elastically deformed only by the weight of the AF operation unit. 
     Furthermore, the initial position of the bobbin  110  may be the position of the AF operation unit when gravity is applied toward the base  210  from the bobbin  110  or toward the bobbin  110  from the base  210 . 
     Next, the second magnet  180  and the third magnet  185  will be described. 
     The second magnet  180  may be referred to as a sensing magnet because the second magnet  180  provides a magnetic field, which is detected by the first position sensor  170 , and the third magnet  185  may be referred to as a balancing magnet, which cancels out the influence from a magnetic field of the sensing magnet  180  and establishes weight equilibrium with respect to the sensing magnet  180 . 
     The second magnet  180  may be disposed in the second magnet-seating groove  180   a  in the bobbin  110 , and a portion of one of the surfaces of the second magnet  180  that faces the first position sensor  170  may be exposed through the second magnet-seating groove  180   a.    
     For example, each of the second and third magnets  180  and  185  disposed at the bobbin  110  may be configured such that the boundary plane between the N pole and the S pole is parallel to a direction perpendicular to the optical axis OA. For example, each of the surfaces of the second and third magnets  180  and  185  that face the first position sensor  170  may be divided into the N pole and the S pole, without being limited thereto. 
     In another embodiment, for example, each of the second and third magnets  180  and  185  disposed at the bobbin  110  may be configured such that the boundary plane between the N pole and the S pole is parallel to the optical axis OA. 
     Although each of the second and third magnets  180  and  185  may be a monopolar magnetized magnet including a single N pole and a single S pole, the disclosure is not limited thereto. 
     In another embodiment, each of the second and third magnets  180  and  185  may be a bipolar magnetized magnet including two N poles and two S poles, or may be a tetrapolar magnetized magnet. 
     The second magnet  180  may be moved together with the bobbin  110  in the optical-axis direction, and the first position sensor  170  may detect the intensity of a magnetic field or the magnetic force of the second magnet  180 , which is moved in the optical-axis direction and may output an output signal (for example, an output voltage) corresponding to the result of the detection. 
     For example, the intensity of the magnetic field detected by the first position sensor  170  may vary according to displacement of the bobbin  110  in the optical-axis direction, and the first position sensor  170  may output an output signal proportional to the intensity of the magnetic field detected by the first position sensor  170 . The controllers  830  and  780  of the camera module or an optical device, which will be described later, may detect the displacement of the bobbin  110  in the optical-axis direction using the output signal from the first position sensor  170 , and may control the drive signal provided to the first coil  120  based on the detected displacement of the bobbin  110 , thereby performing an AF feedback operation. 
     The third magnet  185  may be disposed at the second side portion that is positioned opposite the second side portion of the bobbin  110  at which the second magnet  180  is disposed, so as to face the second magnet  180 . By virtue of the orientation of the second and third magnets  180  and  185 , the magnetic field of the third magnet  185  may counteract the magnetic field of the second magnet  180 , which has an influence on the interaction between the first magnet  130  and the first coil  120  and may thus reduce or eliminate the influence of the magnetic field of the second magnet  180  on an AF operation, thereby making it possible for the embodiment to improve the accuracy of the AF operation. 
     Next, the housing  140  will be described. 
     The housing  140  may accommodate the bobbin  110  therein and may support the first magnet  130  and the circuit board  190  at which the first position sensor  170  is disposed. 
       FIG. 11  is a perspective view illustrating the housing  140  and the first magnet  130  shown in  FIG. 8 .  FIG. 12  is an exploded perspective view illustrating the housing  140 , the first position sensor  170 , and the circuit board  190  shown in  FIG. 8 . 
     Referring to  FIGS. 11 and 12 , the housing  140  may have a hollow column shape overall. For example, the housing  140  may have a polygonal (for example, quadrilateral or octagonal) or circular bore or cavity. The bore in the housing  140  may be a through hole, which is formed through the housing  140  in the optical-axis direction. 
     The housing  140  may include a plurality of side portions  141  and  142 . For example, the housing  140  may include first side portions  141 , which are spaced apart from each other, and second side portions  142 , which are spaced apart from each other. 
     Each of the first side portions  141  of the housing  140  may be disposed or positioned between two adjacent second side portions  142  so as to connect the two adjacent second side portions to each other, and may have a flat surface having a predetermined depth. 
     For example, the first side portions  141  of the housing  140  may be simply referred to as side portions, and the second side portions  142  of the housing  140  may be positioned at the corners of the housing  140  and may thus be alternatively referred to as corners or corner portions. 
     For example, the number of first side portions  141  of the housing  140  is four, and the number of second side portions  142  is four, without being limited thereto. 
     Although the horizontal length of each of the first side portions  141  of the housing  140  may be greater than the horizontal length of each of the second side portions  142 , the disclosure is not limited thereto. 
     Each of the first side portions of the housing  140  may be disposed parallel to a corresponding one of the side plates of the cover member  300 . 
     For example, the first side portions  141  of the housing  140  may correspond to the first side portions  110   b - 1  of the bobbin  110 , and the second side portions  142  of the housing  140  may correspond to or face the second side portions  110   b - 2  of the bobbin  110 . 
     The first magnet  130  may be disposed or mounted on the first side portions  141  of the housing  140 . Each of the second side portions  142  of the housing  140  may be disposed between two adjacent first side portions  141  so as to connect the two adjacent first side portions to each other. 
     The housing  140  may have a seating groove  146 , which is formed at a location corresponding to the projection  112  of the bobbin  110 . 
     For example, when the initial position of the bobbin  110  is set to the state in which the lower surface of the projection  111  of the bobbin  110  is in contact with the bottom surface  146   a  of the seating groove  146  in the housing  140 , the autofocusing function may be controlled in a single direction (for example, in the positive z-axis direction from the initial position). 
     Alternatively, when the initial position is set to the state in which the lower surface of the projection  111  of the bobbin is spaced apart from the bottom surface  146   a  of the seating groove  146  in the housing  140  by a predetermined distance, the autofocusing function may be controlled in both directions (for example, in the positive z-axis direction and in the negative z-axis direction from the initial position). 
     The housing  140  may include a first-magnet-seating portion  141   a  for receiving the first magnet  130 , a seating groove  141 - 1  for receiving the circuit board  190  and a first-position-sensor-seating groove  141 - 2  for receiving the first position sensor  170 . 
     The first-magnet-seating portion  141   a  may be formed in the inner and lower end of at least one of the first side portions  141  of the housing  140 . For example, the first-magnet-seating portion  141   a  may be formed in the inner and lower end of each of the four first side portions  141 , and each of the first magnets  130 - 1  to  130 - 4  may be fitted or secured into a corresponding one of the first-magnet-seating portions. 
     The first-magnet-seating portion  141   a  in the housing  140  may be configured to have a recess having a size corresponding to the size of the first magnet  130 . The bottom surface of the first-magnet-seating portion  141   a  of the housing  140  that faces the second coil  230  may have an opening formed therein, and the bottom surface of the first magnet  130  secured to the first-magnet-seating portion  141   a  may face the second coil  230  in the optical-axis direction. 
     The seating groove  141 - 1  may be formed in the upper portion or end of one of the second side portions  142  of the housing  140 . For easy mounting of the circuit board  190 , the seating groove  141 - 1  may have a groove structure, which is open at the upper portion thereof and has an lateral surface and a bottom, and may have an opening formed in the inner surface of the housing  140 . The bottom of the seating groove  141 - 1  may have a shape that corresponds to or coincides with the shape of the circuit board  190 . 
     The first-position-sensor-seating groove  141 - 2  may be formed in the bottom of the seating groove  141 - 1  and may have a structure that is depressed from the bottom of the seating groove  141 - 1 , without being limited thereto. 
     For easy mounting of the first position sensor  170 , the first-sensor-seating groove  141 - 2  may have a groove shape, which is open at the upper portion thereof and has a side surface and a bottom, and may have an opening formed in the inner surface of the second side portion  142  of the housing  140 . The first-position-sensor-seating groove  141 - 2  may have a shape that corresponds to or coincides with the shape of the first position sensor  170 . 
     Each of the first magnet  130  and the circuit board  190  may be secured to a corresponding one of the first-magnet-seating portion  141   a  and the seating groove  141 - 1  via an adhesive member, for example, epoxy or double-sided adhesive tape. The first position sensor  170  may be secured to the first-position-sensor-seating portion  141 - 2  via an adhesive member. 
     Each of the first side portions of the housing  140  may be disposed parallel to a corresponding one of the side plates of the cover member  300 . The surface area of each of the first side portions  141  of the housing  140  may be larger than the surface area of each of the second side portions  142 . 
     Each of the second side portions  142  of the housing  140  may have a through hole  147 , which defines a path through which the support member  220  extends. For example, the housing  140  may have through holes  147  formed through the upper portions of the second side portions  142 . 
     In another embodiment, each of the through holes formed in the second side portions may have a structure depressed from the outer surface of the second side portion  142  of the housing  140 , and at least a portion of the through hole may be open at the outer surface of the second side portion  142 . 
     The number of through holes  147  in the housing  140  may be the same as the number of support members. First ends of the support members  220  may extend through the through holes  147 , and may be connected or bonded to the upper elastic member  150 . 
     In order to prevent the housing  140  from directly colliding with the inner surface of the upper end of the cover member  300  shown in  FIG. 8 , the housing  140  may be provided on the upper end thereof with stoppers  144 - 1  to  144 - 4 . 
     For example, the second side portions  142  of the housing  140  may be respectively provided on the upper surfaces thereof with the stoppers  144 - 1  to  144 - 4 . 
     The housing  140  may include at least one upper support protrusion  143 , which is coupled to the outer frame  152  of the upper elastic member  150 . 
     The upper support protrusion  143  of the housing  140  may be formed on the upper surface of at least one of the first side portions  141  and the second side portions  142  of the housing  140 . For example, although the upper support protrusion  143  of the housing  140  may be provided on the upper surface of the second side portion of the housing  140 , the disclosure is not limited thereto. 
     The housing  140  may be provided on the lower surface thereof with a lower support protrusion (not shown), which is coupled and secured to the outer frame  162  of the lower elastic member  160 . 
     In order to provide a space that not only defines a path through which the support member  220  extends but also receives gel-type silicone capable of serving as a damper, the housing  140  may have recesses  142   a  formed in the lower portion or the end of the second side portions  142 . 
     In order to diminish vibration of the support member  220 , at least one of the through hole  147  and the recess  142   a  in the housing  140  may be filled with a damping member, for example silicone. 
     The housing  140  may include at least one stopper  149  projecting from the outer surface of the first side portion  141 . The at least one stopper  149  may prevent the housing  140  from colliding with the side plate of the cover member  300  when the housing  140  is moved in the second direction and/or in the third direction. 
     In order to prevent the lower surface of the housing  140  from colliding with the base  210  and/or the circuit board  250 , the housing  140  may further include a stopper projecting from the lower surface thereof. 
     At the initial position of the AF operation unit, the first magnets  130 - 1  to  130 - 4  may be disposed at the housing  140  so as to partially overlap the first coil  120  in a direction parallel to a straight line, which is perpendicular to the optical axis OA and extends through the optical axis. 
     For example, each of the first magnets  130 - 1  to  130 - 4  may be fitted or disposed in the seating portion  141   a  in a corresponding one of the first side portions  141  of the housing  140 . 
     In another embodiment, the first magnets  130 - 1  to  130 - 4  may be disposed on the outer surfaces of the first side portions  141  of the housing  140  or on the inner or outer surfaces of the second side portions  142  of the housing  140 . 
     Although each of the first magnets  130 - 1  to  130 - 4  may have a quadrilateral parallelepiped shape corresponding to the side portion  141  of the housing  140 , the disclosure is not limited thereto. In another embodiment, one surface of the first magnet that faces a corresponding surface of the first coil  120  may have a curvature corresponding to or coinciding with the curvature of the corresponding surface of the first coil  120 . 
     Each of the first magnets  130  may be composed of a single body and may be configured such that the surface thereof that faces the first coil becomes the S pole and the opposite surface becomes the N pole. However, the disclosure is not limited thereto, and the first magnet  130  may be configured such that the surface thereof that faces the first coil  120  becomes the N pole and the opposite surface becomes the S pole. 
     The first magnets  130 - 1  to  130 - 4  may be disposed and mounted on the first side portions of the housing  140  such that two or more of the first magnets face each other. 
     For example, two pairs of first magnets  130 - 1  to  130 - 4  may be disposed at the first side portions  141  of the housing  140  such that the first magnets in each pair face each other. Here, each of the first magnets  130 - 1  to  130 - 4  may have an approximately quadrilateral shape or may have a triangular shape or a diamond shape in plan view. 
     In another embodiment, only one pair of first magnets may be disposed at two first side portions of the housing  140  that face each other. 
       FIG. 14  is a cross-sectional view of the lens moving apparatus  100  taken along line A-B in  FIG. 9 .  FIG. 15  is a cross-sectional view of the lens moving apparatus  100  taken along line C-D in  FIG. 9 . 
     Referring to  FIGS. 14 and 15 , each of the second and third magnets  180  and  185  may not overlap the first coil  120  in a direction parallel to a line that is perpendicular to the optical axis OA and extends through the optical axis, without being limited thereto. 
     At the initial position of the AF operation unit, the second magnet  180  may overlap or be aligned with the third magnet  185  in a direction parallel to a line that is perpendicular to the optical axis OA and extends through the optical axis. 
     At the initial position of the AF operation unit, the first position sensor  170  may overlap each of the second and third magnets  180  and  185  in a direction parallel to a line that is perpendicular to the optical axis OA and extends through the optical axis, without being limited thereto. In another embodiment, the first position sensor  170  may not overlap at least one of the second and third magnets  180  and  185  in a direction parallel to a line that is perpendicular to the optical axis OA and extends through the optical axis. 
     Next, the first position sensor  170  and the circuit board  190  will be described. 
       FIG. 13A  is an enlarged view illustrating the circuit board  190  and the first position sensor  170  shown in  FIG. 12 .  FIG. 13B  is a block diagram of the first position sensor  170  shown in  FIG. 13A . 
     Referring to  FIGS. 13A and 13B , the circuit board  190  may be disposed at one of the side portions of the housing  140 . For example, the circuit board  190  may be disposed at one of the second side portions  142  of the housing  140 . 
     The first position sensor  170  may be disposed or mounted on the circuit board  190  disposed at the housing  140 , and may be secured to the housing  140 . For example, the circuit board  190  may be disposed in the seating groove  14   a  in the housing  140 . For example, the first position sensor  170  may be moved together with the housing  140  during a handshake correction operation. 
     The first position sensor  170  may detect the intensity of the magnetic field of the second magnet  180  mounted on the bobbin  110  while the bobbin  110  is moved, and may output an output signal corresponding to the result of the detection. 
     In the embodiment shown in  FIG. 8 , although the first position sensor  170  may detect the intensity of the magnetic field of the second magnet  180  and may thus detect the displacement of the bobbin  110 , the disclosure is not limited thereto. In another embodiment, the second and third magnets may be omitted, and the first position sensor  170  may output an output signal corresponding to the result of the detection of the intensity of the magnetic field of the first magnet, and may detect or control the displacement of the bobbin  110  using the output signal. 
     Although the first position sensor  170  may be disposed at the lower surface of the circuit board  190 , the disclosure is not limited thereto. In another embodiment, the first position sensor  170  may be disposed at any of various positions. 
     Here, the lower surface of the circuit board  190  may be the surface of the circuit board  190  that faces the upper surface of the housing  140  or comes into contact with the seating groove  141 - 1  in the housing  140 . 
     Referring to  FIG. 13B , the first position sensor  170  may include a hall sensor  61  and a driver  62 . 
     For example, the hall sensor  61  may be made of a silicon-based material. The output VH of the hall sensor  61  may increase as the ambient temperature increases. 
     In another embodiment, the hall sensor  61  may be made of GsAs, and the output VH of the hall sensor  61  may have a gradient of −0.06%/° C. according to an ambient temperature. 
     The first position sensor  170  may further include a temperature-sensing element  63  capable of detecting an ambient temperature. The temperature-sensing element  63  may output a temperature-sensing signal Ts according to the ambient temperature detected in the vicinity of the first position sensor  170  to the driver  62 . 
     For example, the hall sensor  61  of the first position sensor  190  may generate the output VH according to the detected intensity of the magnetic force of the second magnet  180 . For example, the level of the output of the first position sensor  190  may be proportional to the intensity of the magnetic force of the second magnet  180 . 
     The driver  62  may output a drive signal dV for driving the hall sensor  61  and a drive signal Id 1  for driving the first coil  120 . 
     For example, the driver  62  may receive a clock signal SCL, a data signal SDA, and power signals VDD and GND via data communication using a protocol such as I2C communication. 
     The driver  62  may create the drive signal dV for driving the hall sensor  61  and the drive signal Id 1  for driving the first coil  120  using the clock signal SCL and the power signals VDD and GND. 
     Here, the first power signal GND may be a ground voltage or 0V, and the second power signal VDD may be a predetermined voltage for driving the driver  62 , and may be DC voltage and/or AC voltage, without being limited thereto. 
     The driver  62  may receive the output VH from the hall sensor  61 , and may send the clock signal SCL and the data signal SDA, pertaining to the output VH of the hall sensor  61  via data communication using a protocol such as I2C communication, to the controllers  830  and  780 . 
     Furthermore, the driver  62  may receive the temperature-sensing signal Ts detected by the temperature-sensing element  63 , and may send the temperature-sensing signal Ts to the controller  830  via data communication using a protocol such as I2C communication. 
     The controller  830  may perform temperature compensation for the output VH from the hall sensor  61  based on variation in the ambient temperature detected by the temperature-sensing element  63  of the first position sensor  170 . 
     For example, when the drive signal dV or a bias signal of the hall sensor  61  is 1 mA, the output VH of the hall sensor  61  of the first position sensor  170  may range from −20 mV to +20 mV. 
     In the case of temperature compensation for the output VH of the hall sensor  61 , having a negative gradient with respect to variation in ambient temperature, the output VH of the hall sensor  61  of the first position sensor  170  may range from 0 mV to +30 mV. 
     When the output of the hall sensor  61  of the first position sensor  170  is plotted on an x-y coordinate system, the reason why the output range of the hall sensor  61  of the first position sensor  170  is represented in the first quadrant (for example, 0 mV to +30 mV) is as follows. 
     Because the output of the hall sensor  61  in the first quadrant of the x-y coordinate system and the output of the hall sensor  61  in the third quadrant of the x-y coordinate system move in opposite directions depending on variation in ambient temperature, the accuracy and reliability of the hall sensor may be decreased when both the first and third quadrant are used as an AF operation control zone. Accordingly, in order to accurately compensate for variation in ambient temperature, a specific range in the first quadrant may be considered to be the output range of the hall sensor  61  of the first position sensor  170 . 
     The first position sensor  170  may include four terminals for sending and receiving the clock signal SCL, the data signal SDA and the power signals VDD and GND and two terminals for providing a drive signal to the first coil  120 . 
     For example, the first position sensor  170  may include the first to third terminals for the clock signal SCL and the two power signals VDD and GND, the fourth terminal for the data SDA, and the fifth and sixth terminals for providing drive signals to the first coil  120 . 
     Each of the first to sixth terminals of the first position sensor  170  may be conductively connected to a corresponding one of the terminals or pads  190 - 1  to  190 - 6  of the circuit board  190 . 
     The circuit board  190  may include the first to sixth terminals, provided on the upper surface thereof, and a circuit pattern or wiring (not shown). 
     Referring to  FIG. 13A , the circuit board  190  may include a body portion  90 - 1 , a first bent portion  90 - 2  which is bent at one end of the body portion  90 - 1 , and a second bent portion  90 - 3  which is bent at the other end of the body portion  90 - 1 . 
     For example, the first and second bent portions  90 - 2  and  90 - 3  may be bent in the same direction with respect to the body portion  90 - 1 . 
     For example, the circuit board  190  disposed at the housing  140  may include a first lateral surface  6   a  which faces the optical axis OA and a second lateral surface  6   b  positioned opposite the first lateral surface  6   a . The first lateral surface  6   a  of the circuit board  190  may have a flat shape, and the second lateral surface  6   b  of the circuit board  190  may have a bent shape. 
     In  FIG. 13A , although the circuit board  190  is bent at two ends thereof so as to allow easy bonding to the upper elastic member, the disclosure is not limited thereto. In another embodiment, the circuit board  190  may not have the bent shape, and may have a linear shape. 
     Although the first to sixth terminals  190 - 1  to  190 - 6  may be disposed on the upper surface of the circuit board  190  in the state in which the terminals are spaced apart from each other so as to allow easy conductive connection to the upper elastic member  150 , the disclosure is not limited thereto. 
     The circuit pattern or wiring (not shown) of the circuit board  190  may conductively connect the first to sixth terminals  190 - 1  to  190 - 6  to the first to sixth terminals of the first position sensor  170 , and may be provided on at least one of the upper and lower surfaces of the circuit board  190 . 
     For example, the circuit board  190  may be a printed circuit board or a flexible PCB (FPCB). 
     In another embodiment, the first position sensor  170  may be disposed on the upper surface of the circuit board  190 , and the terminals  190 - 1  to  190 - 6  may be provided on the lower surface of the circuit board  190 . 
     The first to sixth terminals  190 - 1  to  190 - 6  of the circuit board  190  may be conductively connected to the terminals of the circuit board  250  via the upper elastic member  150  and the support member  220 , and the first position sensor  170  may thus be conductively connected to the circuit board  250 . 
     In another embodiment, the first position sensor  170  may be embodied as only a single position-detecting sensor, such as a hall sensor. 
     Next, the upper elastic member  150 , the lower elastic member  160  and the support member  220  will be described. 
       FIG. 16A  is a plan view of the upper elastic member  150  shown in  FIG. 1 .  FIG. 16B  is a plan view of the lower elastic member  160  shown in  FIG. 8 .  FIG. 17  is an assembled perspective view illustrating the upper elastic member  150 , the lower elastic member  160 , the base  210 , the support member  220 , the second coil  230 , and the circuit board  250  shown in  FIG. 8 .  FIG. 18  is an exploded perspective view illustrating the second coil  230 , the circuit board  250 , the base  210 , and the second position sensor  240  shown in  FIG. 8 . 
     Referring to  FIGS. 16A to 18 , the upper elastic member  150  and the lower elastic member  160  may elastically support the bobbin  110  with respect to the housing  140 . 
     The upper elastic member  150  may be coupled to the upper portion, the upper end or the upper surface of the bobbin  110 , and the lower elastic member  160  may be coupled to the lower portion, the lower end or the lower surface of the bobbin  110 . 
     For example, the upper elastic member  150  may be coupled both to the upper portion, the upper end or the upper surface of the bobbin  110  and to the upper portion, the upper end or the upper surface of the housing  140 , and the lower elastic member  160  may be coupled both to the lower portion, the lower end or the lower surface of the bobbin  110  and to the lower portion, the lower end or the lower surface of the housing  140 . 
     The support member  220  may support the housing  140  so as to allow the housing  140  to be moved in a direction perpendicular to the optical axis, and may conductively connect at least one of the upper and lower elastic members  150  and  160  to the circuit board  250 . 
     Referring to  FIG. 16A , the upper elastic member  150  may include a plurality of upper elastic units  150 - 1  to  150 - 8 , which are conductively isolated from each other. Although  FIG. 16A  illustrates eight upper elastic units, which are conductively isolated from each other, the disclosure is not limited thereto. 
     The upper elastic member  150  may include first to sixth upper elastic units  150 - 1  to  150 - 6 , which are directly bonded to the first to sixth terminals  190 - 1  to  190 - 6  of the circuit board  190  and are conductively connected thereto. 
     Furthermore, the upper elastic member  150  may further include seventh and eighth upper elastic units  150 - 7  and  150 - 8 , which are not conductively connected to the first to sixth terminals  190 - 1  to  190 - 6  of the circuit board  190 . 
     A plurality of upper elastic units may be disposed at the first corner portion of the housing  140 , at which the circuit board  190  is disposed, and at least one upper elastic unit may be disposed at each of the remaining second to fourth corner portions, other than the first corner portion. 
     For example, four upper elastic units  150 - 1  to  150 - 4  may be disposed at the first corner portion of the housing  140 , two upper elastic units  150 - 5  and  150 - 8  may be disposed at the second corner portion of the housing  140 , one upper spring  150 - 6  may be disposed at the third corner portion of the housing  140 , and one upper spring may be disposed at the fourth corner portion of the housing  140 . The reason for this is to allow the upper elastic units  150 - 1  to  150 - 6  to be easily bonded to the six terminals  190 - 1  to  190 - 6  of the circuit board  190 . 
     The upper elastic units  150 - 1 ,  150 - 6 ,  150 - 7  and  150 - 8 , which are respectively disposed at the first to fourth corner portions of the housing  140 , may be coupled both to the upper portion of the housing  140  and to the upper portion of the bobbin  110 . 
     At least one of the first to fourth upper elastic units  150 - 1  to  150 - 4  may include a first inner frame  151  coupled to the bobbin  110 , a first outer frame  152  coupled to a corresponding one of the first to fourth corner portions of the housing  140 , and a first frame connector  153  connecting the first inner frame to the first outer frame. 
     At least one of the fifth to eighth upper elastic units  150 - 5  to  150 - 8  may include a first inner frame  151  coupled to the bobbin  110 , a first outer frame  152  coupled to a corresponding one of the first to fourth corner portions of the housing  140 , and a first frame connector  153  connecting the first inner frame to the first outer frame. 
     For example, the first inner frame  151  may have a through hole h 1  for coupling to the first coupler  113   a  of the bobbin  110 , and the outer frame  152  may have a through hole h 2  for coupling to the upper support protrusion  143  of the housing  140 . 
     Referring to  FIG. 16A , the first to fourth upper elastic units  150 - 1  to  150 - 4 , which are disposed at the first corner portion of the housing  140 , may respectively include first couplers  410   a  to  410   d , which are coupled to the first corner portion of the housing  140 . 
     The first couplers  410   a  to  410   d  of the first to fourth upper elastic units  150 - 1  to  150 - 4  may be respectively provided with contacts P 2  to P 5 , each of which is in contact with or connected to a corresponding one of the first to sixth terminals  190 - 1  to  190 - 6  of the circuit board  190 . 
     Each of the contacts P 2  to P 5  may extend or project from one end of a corresponding one of the first couplers  410   a  to  410   d , and may be bonded to a corresponding one of the terminals of the circuit board  190  via solder or a conductive adhesive member. 
     The first outer frame of each of the first and fourth upper elastic units  150 - 1  and  150 - 4  may be provided with a third coupler  590 , which is coupled to one end of a corresponding one of the first and fourth support members  220 - 1  and  220 - 4 . 
     The second and third upper elastic units  150 - 2  and  150 - 3  may be disposed between the first and fourth upper elastic units  150 - 1  and  150 - 4 . 
     The second and third upper elastic units  150 - 2  and  150 - 3  may respectively include second couplers  420   a  and  420   b , coupled to the second and third support members  220 - 2  and  220 - 3 , and connectors  430   a  and  430   b , connecting the first couplers  410   b  and  410   c  to the second couplers  420   a  and  420   b.    
     The first outer frames  152  of the fifth to eighth upper elastic units  150 - 5  to  150 - 8 , which are respectively disposed at the second to fourth corner portions of the housing  140 , may include first couplers  510 ,  560  and  570 , which are coupled to the second to fourth corner portions of the housing  140 , second couplers  520   a ,  520   b ,  570   a  and  570   b , which are coupled to the fifth to eighth support members  220 - 5  to  220 - 8 , and connectors  530   a ,  530   b ,  580   a  and  580   b , which connect the first couplers  510 ,  560  and  570  to the second couplers  520   a ,  520   b ,  570   a  and  570   b.    
     Using solder or a conductive adhesive member (for example, conductive epoxy)  901  (see  FIG. 17 ), the second and third support members  220 - 2  and  220 - 3  may be conductively connected to the second couplers  420   a  and  420   b , and the fifth to eighth support members  220 - 5  to  220 - 8  may be conductively connected to the second couplers  520   a ,  520   b ,  570   a  and  570   b.    
     The first couplers  410   a  to  410   d ,  510 ,  560  and  570  of the first outer frames of the first to fourth upper elastic members  150 - 1  to  150 - 4  and the fifth to eighth upper elastic members  150 - 5  to  150 - 8  may include one or more coupling regions coupled to the housing  140 , and each of the coupling regions may be embodied as a through hole. 
     Although each of the second couplers  420   a ,  420   b ,  520   a ,  520   b ,  570   a  and  570   b  and the third coupler  590  may have therein a through hole, the disclosure is not limited thereto. In another embodiment, the through hole may be replaced with any of various structures, for example, a groove, enabling coupling to the housing  140 . 
     Each of the connectors  430   a ,  430   b ,  530   a ,  530   b ,  580   a  and  580   b  may have a shape that is bent at least once, and the width W 2  each of the connectors  430   a ,  430   b ,  530   a ,  530   b ,  580   a  and  580   b  may be less than the width W 1  of the first frame connector  153  of the upper elastic member  150  (W 2 &lt;W 1 ). 
     Because the width W 2  is less than the width W 1  (W 2 &lt;W 1 ), the connectors  430   a ,  430   b ,  530   a ,  530   b ,  580   a  and  580   b  may be easily moved in the optical-axis direction, thereby making it possible to distribute the stress applied to the upper elastic member  150  and the stress applied to the support member  220 . 
     Although the width W 1  of the first frame connector  153  of the upper elastic member  150  is greater than the width of each of the second frame connecters  163 - 1  and  163 - 2  of the lower elastic member  160  in this embodiment, the disclosure is not limited thereto. 
     For example, the first outer frames  152  of the sixth and seventh upper elastic units  150 - 6  and  150 - 7  may be symmetrical with respect to reference lines  501  and  502 . Furthermore, the outer frames of the fifth and eighth upper elastic units  150 - 5  and  150 - 8  may be bilaterally symmetrical to each other with respect to the reference line  501 . 
     The reference line  501  may be a straight line that extends through the center point  101  (see  FIG. 16A ) and through the vertices of the second and third corner portions of the housing  140  that face each other, and the reference line  502  may be a straight line that extends through the center point  101  (see  FIG. 16A ) and extends through the vertices of the first and fourth corner portions of the housing  140  that face each other. For example, the center point  101  may be the center of the bobbin  110  or the center of the housing  140 , and the corners of the housing  140  may become the stoppers  144 - 1  to  144 - 4 . 
     The fifth upper spring  150 - 5 , which is disposed at the second corner portion, may include a first upper extension frame  154   a  which extends toward the first corner portion from one end of the first coupler  570  of the first outer frame  152   a . For example, the first upper extension frame  154   a  may be connected at one end thereof to the first outer frame  152   a , and may be coupled at the other end thereof to the terminal  190 - 1  of the circuit board  190 . 
     Furthermore, the sixth upper spring  160 - 6 , which is disposed at the third corner portion, may include a second upper extension frame  154   b , which extends toward the first corner portion from one end of the first coupler  510  of the first outer frame  152 . For example, the second upper extension frame  154   b  may be connected at one end thereof to the first outer frame  152 , and may be coupled at the other end thereof to the terminal  190 - 6  of the circuit board. 
     The first and second upper extension frames  154   a  and  154   b  may be respectively provided with contacts P 1  and P 6 , each of which is in contact with or connected to a corresponding one of the first to sixth pads  190 - 1  to  190 - 6  of the circuit board  190 . 
     Each of the first and second upper extension frames  154   a  and  154   b  may have a through hole h 3 , which is coupled to a corresponding one of the upper support protrusions of the housing  140 . 
     The first couplers  410   a  to  410   d ,  510 ,  560  and  570  may be in contact with the upper surfaces of the corner portions  142  of the housing  140 , and may be supported by the corner portions  142  of the housing  140 . Meanwhile, the connectors  430   a ,  430   b ,  530   a ,  530   b ,  580   a  and  580   b  may not be in contact with the upper surface of the housing  140 , but may be spaced apart from the housing  140 . In order to prevent oscillation due to vibration, the space between the connectors  430   a ,  430   b ,  530   a ,  530   b ,  580   a  and  580   b  and the housing  140  may be filled with a damper (not shown). 
     Referring to  FIG. 16B , the lower elastic member  160  may include a plurality of lower elastic units  160 - 1  and  160 - 2 . 
     For example, each of the first and second upper elastic units  160 - 1  and  160 - 2  may include second inner frames  161 - 1  and  161 - 2 , which are coupled or secured to the lower portion of the bobbin  110 , second outer frames  162 - 1  to  162 - 3 , which are coupled or secured to the lower portion of the housing  140 , second frame connectors  163 - 1  and  163 - 2  connecting the second inner frames  161 - 1  and  161 - 2  to the second outer frames  162 - 1  and  162 - 2 , and connecting frames  164 - 1  and  164 - 2  connecting the second outer frames to each other. 
     Although the width of each of the connecting frames  164 - 1  and  164 - 2  may be less than the width of each of the first inner frames, the disclosure is not limited thereto. 
     In order to avoid spatial interference with the second coils  230  and the first magnets  130 - 1  to  130 - 4 , the connecting frames  164 - 1  and  164 - 2  may be positioned outside the second coils  230 - 1  to  230 - 4  and the first magnets  130 - 1  to  130 - 4 . Here, the outside of the second coils  230 - 1  to  230 - 4  and the first magnets  130 - 1  to  130 - 4  may be the side opposite the center of the bobbin  110  or the center of the housing  140  with respect to the second coils  230 - 1  to  230 - 4  and the first magnets  130 - 1  to  130 - 4 . 
     For example, although the connecting frames  164 - 1  and  164 - 2  may not overlap the second coils  230 - 1  to  230 - 4  in the optical-axis direction, the disclosure is not limited thereto. In another embodiment, at least a portion of the connecting frames  164 - 1  and  164 - 2  may be aligned with or overlap the second coils  230 - 1  to  230 - 4  in the optical-axis direction. 
     The portion at which the connecting frame  164 - 1  of the first lower elastic unit  160 - 1  and the second outer frame  162 - 2  are connected to each other may be provided with a first connecting projection  165 - 1  to which the other end of the first support member  220 - 1  is bonded. 
     The portion at which the connecting frame of the second upper elastic unit  160 - 2  and the second outer frame are connected to each other may be provided with a second connecting projection  165 - 2 , to which the other end of the fourth support member  220 - 4  is bonded. Each of the first and second connecting projections  165 - 1  and  165 - 2  may have a through hole  165   a  to which the other end of a corresponding one of the first and fourth support members  220 - 1  and  220 - 4  is coupled. 
     Each of the upper elastic units  150 - 1  to  150 - 8  and the upper elastic units  160 - 1  and  160 - 2  may be embodied as a leaf spring. However, the upper elastic unit is not limited thereto, and may be embodied as a coil spring or the like. 
     The outer frame (for example,  152  or  162 ) may be alternatively referred to as an outer portion, the inner frame (for example,  151  or  161 ) may be alternatively referred to as an inner portion, and the support member (for example, 220) may be alternatively referred to as a wire. 
     Next, the support members  220 - 1  to  220 - 8  will be described. 
     The support members  220 - 1  to  220 - 8  may be disposed so as to correspond to the second side portions or the corner portions  142  of the housing  140 . 
     The support members  220  may conductively connect two (for example,  150 - 1  and  150 - 4 ) of the upper elastic units  150 - 1  to  150 - 8  to the first and second lower elastic units  160 - 1  and  160 - 2 . Furthermore, the support members  220  may conductively connect four other ones (for example,  150 - 2  and  150 - 3 ) among the upper elastic units  150 - 1  to  150 - 8  to the circuit board  250 . 
     The support members  220 - 1  to  220 - 8  may conductively connect at least one of the upper elastic units, which are positioned at at least one of the corner portions of the housing  140 , to the circuit board. 
     One end of each of the support members  220 - 2 ,  220 - 3 ,  220 - 5  and  220 - 8  may be directly connected or bonded to the second coupler  420   a ,  420   b ,  520   a ,  520   b ,  570   a  and  570   b  of a corresponding one of the second, third and fifth to eighth upper elastic members  150 - 2 ,  150 - 3 ,  150 - 5  to  150 - 8 . 
     The other end of each of the support members  220 - 2 ,  220 - 3  and  220 - 5  to  220 - 8  may be directly connected or bonded to the circuit board  250 . 
     One end of each of the support members  220 - 1  and  220 - 4  may be directly connected or bonded to the third connector  590  of a corresponding one of the first and fourth upper elastic units  150 - 1  and  150 - 4 . The other end of each of the support members  220 - 1  and  220 - 4  may be directly connected or bonded to the through hole  165   a  formed in a corresponding one of the first and second connecting projections  165 - 1  and  165 - 2  of the lower elastic units  160 - 1  and  160 - 2 . 
     A single contact may be formed between each of the second couplers  420   a ,  420   b ,  520   a ,  520   b ,  570   a  and  570   b  and a corresponding one of the first couplers  410   b ,  410   c ,  510 ,  560  and  570  by means of a corresponding one of the connectors  430   a ,  430   b ,  530   a ,  530   b ,  580   a  and  580   b.    
     For example, the support members  220 - 2 ,  220 - 3  and  220 - 5  to  220 - 8  may extend through the through holes  147  (see  FIG. 11 ) formed in the corner portions of the housing  140 . Meanwhile, the support members  220 - 1  and  220 - 4  may be disposed near the boundary line between the first side portions  141  and the corner portions  142  of the housing  140 , and may not extend through the corner portions  142  of the housing  140 . 
     Each of the support members  220 - 1  to  220 - 4  may conductively connect a corresponding one of the first to fourth upper elastic units  150 - 1  to  150 - 4  to the circuit board  250 , independently of the others.

     The OIS position sensors  240   a  and  240   b  may detect displacement of the OIS operation unit in a direction perpendicular to the optical axis. Here, the OIS operation unit may include the AF operation unit and the components mounted on the housing  140 . 
     For example, the OIS operation unit may include the AF operation unit and the housing  140 . In some embodiments, the OIS operation unit may further include the first magnets  130 - 1  to  130 - 4 . For example, the AF operation unit may include the bobbin  110  and components that are mounted on the bobbin  110  and are moved therewith. For example, the AF operation unit may include the bobbin  110 , as well as the lens (not shown), the first coil  120  and the first and second magnets  180  and  185 , which are mounted on the bobbin  110 . 
     The circuit board  250  may be disposed on the upper surface of the base  210 , and may have the bore  25   a  corresponding to the bore in the bobbin  110 , the bore in the housing  140  and/or the bore in the base  210 . The outer circumferential surface of the circuit board  250  may have a shape coinciding with or corresponding to the upper surface of the base  210 , for example, a quadrilateral shape. 
     The circuit board  250  may include at least one terminal member  253 , which is bent from the upper surface of the circuit board and which is provided with a plurality of terminals  251  or pins to which electrical signals are suppled from the outside. Although the circuit board  250  may include, for example, two terminal members that face each other, the disclosure is not limited thereto.

     Drive signals may be respectively provided to the first coil  120  and the second coil  230  via the terminals  251  mounted on the terminal member  253  of the circuit board  250 .

     The drive signal, which is provided to the first coil  120  and/or the second coil  230 , may be a DC and/or AC signal and may be of a current type or a voltage type. 
     In the embodiment, although the circuit board  250  may be an FPCB, the disclosure is not limited thereto, and the terminals of the circuit board  250  may be directly formed on the surface of the base  210  through surface electrode technology. 
     In order to avoid spatial interference with the support members  220 - 1  to  220 - 8 , the circuit board  250  may have escape groove  250   a  formed in the corners or vertices thereof. 
     In another embodiment, in place of the escape grooves  250   a , the corners or vertices of the circuit board  250  may be provided with holes through which the support members  220 - 1  to  220 - 8  extend. 
     For example, although the support members  220 - 1  to  220 - 8  may be conductively connected to the lower surface of the circuit board  250  or the circuit pattern formed on the lower surface via solder or the like, the disclosure is not limited thereto. 
     In another embodiment, the circuit board  250  may not have the escape grooves or holes formed therein, and the support members may be conductively connected to a circuit pattern or pads formed on the upper surface of the circuit board  250  via solder or the like. 
     In a further embodiment, the support members may be conductively connected to the coil board  231 , and the coil board  231  may conductively connect the support members to the circuit board  250 . 
     The second coil  230  may be disposed under the bobbin  110  and/or the housing  140 . 
     For example, the second coil  230  may be disposed on the upper surface of the circuit board  250  so as to face or overlap the first magnets  130 - 1  to  130 - 4  disposed at the housing  140 . 
       FIG. 19  is a plan view of the second coil  230  shown in  FIG. 18 .  FIG. 20  is a bottom view of the second coil  230  shown in  FIG. 19 .  FIG. 21  is a cross-sectional view of the dotted portion in  FIG. 19 . 
     Referring to  FIGS. 19 to 21 , the second coil  230  may include the coil board  231  and coil units  230 - 1  to  230 - 4 , which are provided at the coil board  231  and correspond to the first magnets  130 - 1  to  130 - 4 . The coil board  231  may be alternatively referred to as a circuit member or a board. 
     The coil board  231  may have a polygonal shape (for example, a quadrilateral shape). 
     For example, the coil board  231  may include four sides S 11  to S 14  and four corners S 2 , and may have a bore (or cavity)  231   a  corresponding to the bore in the housing  140 , the bore in the circuit board  250  and/or the bore in the base  210 . 
     The coil board  231  shown in  FIG. 19  may be a unit coil board. The process of forming the unit coil board  231  is as follows. 
     First, a board including a plurality of unit coil boards is prepared. Subsequently, for shaping the unit coil board, a first laser-cutting operation of cutting the board along the sides S 11  to S 14  of the coil board  231  shown in  FIG. 19  is performed. At this time, the board may include bridges, each of which connects two adjacent corners of two adjacent unit coil boards. 
     Subsequently, a second laser-cutting operation of cutting the board along the corners S 2  of the coil boards  231  is performed. In the second laser-cutting operation, the bridges may also be cut together with the corners, and burrs may be created at the cut regions of the bridges. The reason for this is because the laser power required for cutting portions of the coil boards  231  that include Cu (for example, coil units or dummy patterns) is different from the laser power required for cutting portions of the coil boards  231  not including Cu. 
     In the embodiment, burrs may be created at corners of the unit coil boards in the formation of the unit coil boards  231 . However, since each of the corners of the coil board  231  is provided with the escape groove in order to avoid spatial interference with the support members, friction or the like with the cover member does not occur and foreign substances are not generated even when burrs are formed. 
     Because burrs are formed at the corners of the unit coil board, the roughness of the corners S 2  of the coil board  231  may be higher than the roughness of the sides S 11  to S 14  of the coil board  231 . 
     Meanwhile, when each of the bridges connects sides of two adjacent unit coil boards to each other, burrs such as grooves or protrusions may be locally created at the sides of the unit coil board from which the bridges are removed in the second laser-cutting operation, and foreign substances may be generated due to contact or a collision between the side plate of the cover member and the sides of the coil board  231 . 
     Each of the corners S 2  of the coil board  231  may be positioned between two adjacent sides of the coil board  231 , and may connect the two adjacent sides to each other. 
     Each of the coil units  230 - 1  to  230 - 4  may face or overlap a corresponding one of the first magnets  130 - 1  to  130 - 4  in the optical-axis direction. 
     Each of the first to fourth coil units  230 - 1  to  230 - 4  may have a closed curve shape having a central hole, for example a ring shape, and the central hole may be formed in the optical-axis direction. 
     For example, the first coil unit  230 - 1  and the second coil unit  230 - 3  may be disposed so as to face each other in a transverse direction (for example, in the x-axis direction), and the third coil unit  230 - 3  and the fourth coil unit  230 - 4  may be disposed so as to face each other in a vertical direction (for example, in the y-axis direction). 
     Each of the first to fourth coil units  230 - 1  to  230 - 4  may be disposed at a corresponding one of the four sides S 1  of the coil board  231 . 
     For example, each of the first coil unit  2301  and the second coil unit  230 - 2  may be disposed parallel to a corresponding one of the first and second sides S 11  and S 12  of the coil board  231 , which face each other, and each of the third coil unit  230 - 3  and the fourth coil unit  230 - 4  may be disposed parallel to a corresponding one of the third and fourth sides S 13  and S 14 , which face each other. 
     In order to avoid spatial interference with the support members  220 - 1  to  220 - 8 , each of the corners S 2  of the coil board  231  may have an escape groove  23  formed therein, and the support members  220 - 1  to  220 - 8  may be positioned near the escape grooves  23  in the coil board  231 . In another embodiment, in order to avoid spatial interference between the coil board  231  and the support members  220 - 1  to  220 - 8 , the corners of the coil board  231  may be provided with through holes in place of the escape holes  23 . 
     The inner circumferential surface of the coil board  231 , which is formed by the bore  231   a , may be provided with grooves  18   a  which are coupled to the protrusions  19   a  on the base  210 . 
     Referring to  FIG. 20 , the coil board  231  may include at least one terminal. 
     For example, the coil board  231  may include terminals Q 1  to Q 8 . In  FIG. 20 , although the coil board  231  includes eight terminals, the disclosure is not limited thereto. 
     In another embodiment, the coil board  231  may include four terminals (for example, Q 1  to Q 4 ). In this case, the first and second coil units  230 - 1  and  230 - 2  may be connected to each other, and the third and fourth coil units  230 - 3  and  230 - 4  may be connected to each other. The first and second coil units  230 - 1  and  230 - 2 , which are connected to each other, may be conductively connected to two terminals (for example, Q 1  and Q 2 ), and the third and fourth coil units  230 - 3  and  230 - 4 , which are connected to each other, may be conductively connected to two of the other terminals (for example, Q 3  and Q 4 ). 
     In a further embodiment, the coil board  231  may include six terminals (for example, Q 1  to Q 6 ). In this case, two coil units, which face each other, may be connected to each other, and may be conductively connected to two terminals (for example, Q 1  and Q 2 ). Two other coil units, which face each other, may not be connected to each other. One of the two coil units, which are not connected to each other, may be conductively connected to two other terminals (for example, Q 3  and Q 4 ), and the other one of the two coil units, which are not connected to each other, may be conductively connected to the two remaining terminals (for example, Q 5  and Q 6 ). 
     At least one of the terminals Q 1  to Q 8  of the coil board  231  may be conductively connected to the coil units  230 - 1  to  230 - 4 . The terminals of the coil board  231  may be alternatively referred to as pads, conductive bodies, electrodes or bonding portions. 
     The terminals Q 1  to Q 8  of the coil board  231  may be disposed so as to abut on the inner circumferential surface or the inner surface of the coil board  231 , which is formed by the bore  231   a . For example, the terminals Q 1  to Q 8  of the coil board  231  may be arranged so as to be spaced apart from one another along the inner circumferential surface or the inner surface of the coil board  231 . 
     For example, the lower surface of each of the terminals Q 1  to Q 8  of the coil board  231  may be exposed from the lower surface of the coil board  231 . 
     The circuit board  250  may include at least one pad corresponding to at least one terminal of the coil board  231 . 
     For example, the circuit board  250  may include pads  25 - 1  to  25 - 4 , and each of the pads  25 - 1  to  25 - 4  of the circuit board  250  may be conductively connected to a corresponding one of the terminals (for example, Q 1  to Q 4 ) of the coil board  231 . Although the circuit board  250  includes four pads  25 - 1  to  25 - 4  connected to the four terminals Q 1  to Q 4  of the coil board  231 , the disclosure is not limited thereto. Depending on the conductive connection relationship of the coil units  230 - 1  to  230 - 5 , the circuit board  250  may include two, three, or five or more pads for conductive connection to the coil units. 
     The coil board  231  may include a first marker  271 , and the circuit board  250  may include a second marker  281  corresponding to the first marker  281 . Although the first marker  271  may be positioned, for example, between the first coil unit  230 - 1  and the fourth coil unit  230 - 4 , the disclosure is not limited thereto. The first marker  271  and the second marker  281  may be serve as markers for correctly aligning the terminals Q 1  to Q 4  of the coil board  231  with the pads  25 - 1  to  25 - 4  of the circuit board  250  in an operation of conductively connecting the terminals Q 1  to Q 4  of the coil board  231  to the pads  25 - 1  to  25 - 4  of the circuit board  250 . 
     In another embodiment, the second coil  230  may include one coil unit for the second direction and one coil unit for the third direction, and may include four or more second coil units. 
     The housing  140  may be moved in the second direction and/or in the third direction, for example, in the x-axis direction and/or in the y-axis direction, by the electromagnetic force resulting from the interaction between the first magnets  130 - 1  to  130 - 4  and the second coil units  230 - 1  to  230 - 4 , which are disposed so as to face each other in the optical-axis direction. For example, the controllers  830  and  780  may perform handshake correction for the lens moving apparatus  100  by controlling a drive signal provided to coil units  230 - 1  to  230 - 4 . 
     The lens moving apparatus  100  may further include the second position sensor  240  for OIS feedback operation. The second position sensor  240  may include the first OIS position sensor  240   a  and the second OIS position sensor  240   b.    
     Each of the OIS position sensors  240   a  and  240   b  may be a hall sensor, and any sensor can be used, as long as the sensor is capable of detecting the intensity of a magnetic field. For example, each of the position sensors  240   a  and  240   b  may be embodied as a driver including a hall sensor, or may be embodied as a position-detecting sensor such as a hall sensor alone. 
     For example, although the first OIS position sensor  240   a  and the second OIS position sensor  240   b  may be disposed or mounted on the lower surface of the circuit board  250  and the first and second OIS sensors  240   a  and  240   b  may be disposed in the seating grooves  215 - 1  and  215 - 2  in the base  210 , the disclosure is not limited thereto. In another embodiment, the first and second OIS position sensors  240   a  and  240   b  may be disposed on the upper surface of the circuit board  250 . 
     At least a portion of the first OIS position sensor  240   a  may overlap the first coil unit  230 - 1  in the optical-axis direction, and at least a portion of the second OIS position sensor  240   b  may overlap the fourth coil unit  230 - 4  in the optical-axis direction. 
     The first and second OIS position sensors  240   a  and  240   b  may be conductively connected to the terminals  251  of the circuit board  250 . For example, drive signals may be provided to the first OIS and second position sensors  240   a  and  240   b  via the terminals  251  of the circuit board  250 , and the second outputs from the first and second OIS position sensors  240   a  and  240   b  may be output via the terminals  251  of the circuit board  250 . 
     The controller  830  of the camera module or the controller  780  of a portable terminal  200 A may sense or detect displacement of the OIS operation unit using the first output of the first OIS position sensor  240   a  and the second output of the second OIS position sensor  240   b  and may perform OIS feedback control for the OIS operation unit based on the detected displacement of the OIS operation unit. 
     The cover member  300  may accommodate at least one of 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 third magnet  185 , the circuit board  190 , the support member  220 , the second coil  230 , the second position sensor  240 , and the circuit board  250  in the space defined between the cover member  300  and the base  210 . 
     The cover member  300  may have a box shape, which is open at the lower portion thereof and includes the upper plate and the side plate, and the lower portion of the cover member  300  may be coupled to the upper portion of the base  210 . The upper plate of the cover member  300  may have a polygonal shape, for example, a quadrilateral shape or an octagonal shape. 
     The cover member  300  may have a bore or a cavity formed through the upper plate thereof, through which the lens (not shown) coupled to the bobbin  110  is exposed to external light. Although the cover member  300  may be made of nonmagnetic material such as stainless steel in order to prevent attraction to the first magnet  130 , the disclosure is not limited thereto. In another embodiment, the cover member may be made of magnetic material. 
     For example, the length L 1  of the first coil unit  230 - 1  may be different from the length L 2  of the second coil unit  230 - 2 , and the length of the third coil unit  230 - 3  may be different from the length of the fourth coil unit  230 - 4 , without being limited thereto. In another embodiment, the two lengths may be equal to each other. Furthermore, for example, the length L 1  of the first coil unit  230 - 1  and the length of the third coil unit  230 - 2  may be equal to each other, and the length L 2  of the second coil unit  230 - 2  and the length of the fourth coil unit  230 - 4  may be equal to each other, without being limited thereto. In another embodiment, the two lengths may be different from each other. 
     For example, the width W 1  of the first coil unit  230 - 1  and the width W 2  of the second coil unit  230 - 2  may be equal to each other, and the width of the third coil unit  230 - 3  and the width of the fourth coil unit  230 - 4  may be equal to each other, without being limited thereto. In another embodiment, the two widths may be different from each other. Furthermore, for example, the width W 1  of the first coil unit  230 - 1  and the width of the third coil unit  230 - 3  may be equal to each other, and the width of the second coil unit  230 - 2  and the width of the fourth coil unit  230 - 4  may be equal to each other, without being limited thereto. In another embodiment, the two widths may be different from each other. 
     Referring to  FIGS. 19 and 21 , the first coil unit  230 - 1  may be disposed in a first area between the first side S 11  of the coil board  231  and the bore  231   a  in the coil board  231 , and may have a first number of turns. The second coil unit  230 - 2  may be disposed in a second area between the second side S 12  of the coil board  231  and the bore  231   a  in the coil board  231 , and may have a second number of turns. The third coil unit  230 - 3  may be disposed in a third area between the third side S 13  of the coil board  231  and the bore  231   a  in the coil board  231 , and may have a third number of turns. The fourth coil unit  230 - 4  may be in a fourth area between the fourth side S 14  of the coil board  231  and the bore  231   a  in the coil board  231 , and may have a fourth number of turns. 
     Each of the first to fourth coil units  230 - 1  to  230 - 4  may include a line having a plural number of turns. 
     For example, each of the first to fourth coil units  230 - 1  to  230 - 4  may have a continuous spiral, elliptical, and/or track-shaped pattern. 
     For example, the line PA 1  may be made of a conductive body. For example, the line PA 1  may be made of conductive metal, for example, copper, gold, aluminum, silver or an alloy including at least one thereof. 
     The line PA 1  of each of the first to fourth coil units  230 - 1  to  230 - 4  may be formed in a corresponding one of the first to fourth areas of the coil board  231 . 
     Each of the first to fourth coil units  230 - 1  to  230 - 4  may include a first layer Layer 11  and a second layer Layer 12  disposed on the first layer Layer 11 . 
     The first layer Layer 11  may have a continuous spiral, elliptical or track shape. Furthermore, the second layer Layer 12  may have a continuous spiral, elliptical or track shape. 
     The first layer Layer 11  and the second layer Layer 12  may overlap each other in the optical-axis direction and may have the same line width. 
     Although  FIG. 21  illustrates only the first layer and the second layer of the first coil unit  230 - 1 , the description of the first layer Layer 11  and the second layer Layer 12  shown in  FIG. 21  may also be applied to the first layers and the second layers of the second to fourth coil units  230 - 2  to  230 - 4 . 
     Although the thickness T 1  of the first layer Layer 11  and the thickness T 1  of the second layer Layer 12  may be equal to each other, the disclosure is not limited thereto. In another embodiment, the two thicknesses may be different from each other. 
     The first layer Layer 11  of each of the first to fourth coil units  230 - 1  to  230 - 4  may include a plurality of first lines R 1  to Rn (n being a natural number greater than 1, n&gt;1), which are arranged in a corresponding one of the first to fourth areas of the coil board  231 . 
     Furthermore, the second layer Layer 12  of each of the first to fourth coil units  230 - 1  to  230 - 4  may include a plurality of second lines P 1  to Pn (n being a natural number greater than 1, n&gt;1), which are arranged in a corresponding one of the first to fourth areas of the coil board  231 . The first lines R 1  to Rn or the second lines P 1  to Pn may be alternatively referred to as conductive lines or coil pattern lines. 
     For example, although the first lines R 1  to Rn and the second lines P 1  to Pn may be aligned with or overlap each other in the optical-axis direction, the disclosure is not limited thereto. For example, although the number of first lines R 1  to Rn and the number of second lines P 1  to Pn may be the same as each other, the disclosure is not limited thereto. In another embodiment, the two numbers may be different from each other. 
     Each of the first to fourth coil units  230 - 1  to  230 - 4  may include a via  55   a , which connects one end of one of the first lines R 1  to Rn (for example, R 1 ) to one end of one of the second lines P 1  to Pn (for example, P 1 ). 
     Two of the first to fourth coil units  230 - 1  to  230 - 4  may be connected to each other, and the two coil units that are connected to each other may be conductively connected to two of the pads of the coil board  231 . 
     The two remaining ones of the first to fourth coil units  230 - 1  to  230 - 4  may be connected to each other, and the two remaining coil units, which are connected to each other, may be conductively connected to the two remaining pads of the coil board  231 . 
     For example, one end of the first coil unit  230 - 1  and one end of the second coil unit  230 - 2  may be connected to each other, the other end of the first coil unit  230 - 1  may be connected to one (for example, Q 1 ) of the pads of the coil board  231 , and the other end of the second coil unit  230 - 3  may be connected to another one (for example, Q 2 ) of the pads of the coil board  231 . 
     Furthermore, one end of the third coil unit  230 - 3  and one end of the fourth coil unit  230 - 4  may be connected to each other, the other end of the third coil unit  230 - 3  may be connected to a further one (for example, Q 3 ) of the pads of the coil board  231 , and the other end of the fourth coil unit  230 - 4  may be connected to a further one (for example, Q 4 ) of the pads of the coil board  231 . 
     The conductive connection between the first to fourth coil units  230 - 1  to  230 - 4  and the pads of the coil board  231  is not limited to the above-mentioned manner, and the first to fourth coil units  230 - 1  to  230 - 4  and the pads of the coil board  231  may be connected to each other in various manners. 
     Referring to  FIG. 21 , the second coil  230  may include first insulation layers  71 , the first layers Layer 11  of the first to fourth coil units  230 - 1  to  230 - 4  disposed on the first insulation layers  71 , second insulation layers  73  disposed on the first layers Layer 11 , the second layers Layer 12  of the first to fourth coil units  230 - 1  to  230 - 4  disposed on the second insulation layers  73 , and third insulation layers  75  disposed on the second layers. 
     Each of the first and third insulation layers  71  and  75  may include a resin layer made of resin (for example, epoxy) and a polyimide layer (or polyimide tape) including polyimide. For example, each of the first and third insulation layers  71  and  75  may include a solder resist. 
     The second insulation layer  73  may include macromolecular organic compound or resin. For example, the second insulation layer  73  may include polyimide and epoxy bond. 
     For example, the first layer Layer 11  of each of the first to fourth coil units  230 - 1  to  230 - 4  may be disposed between the first insulation layer  71  and the second insulation layer  73 , and the second layer Layer 12  of each of the first to fourth coil units  230 - 1  to  230 - 4  may be disposed between the second insulation layer  73  and the third insulation layer  75 . 
     The second coil  230  may further include a fourth insulation layer  72 , disposed between the first lines R 1  to Rn of each of the first to fourth coil units  230 - 1  to  230 - 4 , and a fifth insulation layer  74 , disposed between the second lines P 1  to Pn of each of the first to fourth coil units  230 - 1  to  2304 . 
     In other words, the fourth insulation layer  72  may be disposed between the first insulation layer  71  and the second insulation layer  73 , and the fifth insulation layer  74  may be disposed between the second insulation layer  73  and the third insulation layer  75 . 
     For example, each of the first insulation layer  71  and the third insulation layer  75  may be alternatively referred to as a cover layer. 
     For example, the coil board  231  may include the first to fifth insulation layers  71  to  75 , the first layer Layer 11  of each of the first to fourth coil units  230 - 1  to  230 - 4  may be formed between the first insulation layer  71  and the second insulation layer  73 , and the second layer Layer 12  may be formed between the second insulation layer  73  and the third insulation layer  75 . The terminals Q 1  to Q 8  of the coil board  231  may be formed under the second insulation layer  73 . 
       FIG. 22  is a partial cross-sectional view of the coil board  231  taken along line C-D in  FIG. 9 . 
     Referring to  FIGS. 21 and 22 , the second insulation layer  73  may include a polyimide layer  73   a . The second insulation layer  73  may further include an adhesive  73   b   1  disposed on the upper surface of the polyimide layer  73   a . The second insulation layer  73  may further include an adhesive  73   b   2  disposed on the lower surface of the polyimide layer  73   a.    
     For example, the adhesive  73   b   1  and  73   b   2  may include epoxy bond. 
     For example, the first insulation layer  71  may include a first resin layer  7   a   1 , which is disposed under the fourth insulation layer  72  and the first layer Layer 11 . The first insulation layer  71  may further include a first polyimide layer  7   b   1  disposed under the first resin layer  7   a   1 . 
     The first insulation layer  71  may further include a first adhesive  7   c   1  disposed between the first resin layer  7   a   1  and the first polyimide layer  7   b   1 . 
     For example, the third insulation layer  75  may include a second resin layer  7   a   2  disposed on the fifth insulation layer  74  and the second layer Layer 12 . The third insulation layer  75  may further include a second polyimide layer  7   b   2  disposed on the second resin layer  7   a   2 . 
     The third insulation layer  75  may further include a second adhesive  7   c   2  disposed between the second resin layer  7   a   2  and the second polyimide layer  7   b   2 . 
     For example, the thickness K 11  of the second polyimide layer  7   b   2  may range from 25 μm to 75 μm, and the thickness K 21  of the second resin layer  7   a   2  may range from 12.5 μm to 50 μm. 
     For example, although the thickness of the first polyimide layer  7   b   1  may be equal to the thickness K 11  of the second polyimide layer  7   b   2 , the disclosure is not limited thereto. The two thickness may be different from each other. 
     Although the thickness of the first resin layer  7   a   1  may be equal to the thickness K 21  of the second resin layer  7   a   2 , the disclosure is not limited thereto. The two thickness may be different from each other. 
     For example, although the thicknesses of the polyimide layers  7   b   2  and  7   b   1  may be respectively equal to or greater than the thicknesses of the resin layer  7   a   1  and  7   a   2 , the disclosure is not limited thereto. In another embodiment, the thicknesses of the polyimide layers  7   b   2  and  7   b   1  may be respectively less than the thicknesses of the resin layers  7   a  and  7   a   2 . 
     For example, although the thickness T 1  of each of the first layer Layer 11  and the second layer Layer 12  may range from 45 μm to 50 μm, the disclosure is not limited thereto. 
     The lower surface  40   a  of each of the terminals Q 1  to A 8  of the coil board  231  is exposed from the first insulation layer  71 , and the first lateral surface  40   b  of each of the terminals Q 1  to Q 8  of the coil board  231  may be open or exposed at the inner circumferential surface  41  of the coil board  231 , which is formed by the bore  231   a  in the coil board  2341 . Here, the first lateral surface  40   b  of each of the terminals Q 1  to Q 8  of the coil board  231  may be the lateral surface of each of the terminals Q 1  to Q 8  of the coil board  231  that faces the inner circumferential surface  40   b  of the coil board  231 . 
     For example, the lower surface  40   a  of each of the terminals Q 1  to Q 8  of the coil board  231  may be exposed by removing a portion of the first insulation layer  71 . For example, the lower surface  40   a  of each of the terminals Q 1  to Q 8  of the coil board  231  may be exposed downwards in the optical-axis direction. 
     The first lateral surface  40   b  of each of the terminals Q 1  to Q 8  of the coil board  231  may be positioned at a surface  401  that is the same surface as the inner circumferential surface  41  of the coil board  231 . 
     For example, the first lateral surface  40   b  may constitute a single surface  401 , which is the same surface as the inner circumferential surface  41  of the coil board  231 . 
     The first lateral surface  40   b  of each of the terminals of the coil board  231  may be exposed in the direction of the center of the bore  231   a  or in the direction of the optical axis of the coil board  231 . 
     For example, the first lateral surface  40   b  of each of the terminals of the coil board  231  may be a curved surface and may have the same curvature radius as that of the inner circumferential surface  41  of the coil board  231 , without being limited thereto. In another embodiment, the two curvature radii may be different from each other. 
     The exposed lower surface  40   a  of each of the terminals Q 1  to Q 8  of the coil board  231  may be positioned higher than the lower surface of the first insulation layer (for example, the lower surface of the first polyimide layer  7   a   1 ). 
     The thickness of each of the terminals Q 1  to Q 8  of the coil board  231  and the thickness of the first layer Layer 11  may be equal to each other. The reason for this is because the first layer Layer 11  of each of the first to fourth coil units  230 - 1  to  230 - 4  and the conductive layer (for example, a copper layer) for the terminals Q 1  to Q 8  of the coil board  231  may be positioned between the first insulation layer  71  and the second insulation layer  73 , and may be patterned simultaneously. 
     In another embodiment, the thickness of each of the terminals Q 1  to Q 8  of the coil board  231  and the thickness of the first layer Layer 11  of each of the first to fourth coil units  230 - 1  to  230 - 4  may be different from each other. For example, the thickness of each of the terminals Q 1  to Q 8  of the coil board  231  may be greater or less than the thickness of the first layer Layer 11 . 
       FIG. 23A  illustrates a cutting line for formation of a terminal and a bore of a conventional coil board  31 .  FIG. 23B  illustrates burrs  36 , which are formed in an operation of forming the bore in the coil board  31 . 
     Referring to  FIGS. 23A and 23B , the coil board  31  is cut along the cutting line  51  using a laser, thereby forming the bore in the coil board  31 . In the case in which a terminal  35  is positioned so as to be spaced apart from the cutting line  51 , the terminal  35  may not be exposed at the inner circumferential surface of the coil board  31 , and burrs  36  may be generated at the inner circumferential surface of the coil board  31  due to the laser cutting. Hence, the burrs  36  may deteriorate the solderability between the terminal  35  of the coil board  31  and the pad (or the pad) of the circuit board (for example,  250 ), thereby deteriorating conductive contact between the two terminals. 
       FIG. 24  illustrates the terminal Q 1  of the coil board  231  and the cutting line  51  for formation of the bore in the coil board  231  according to the embodiment.  FIG. 25A  illustrates the terminal Q 1  of the coil board  231  and the pad  25 - 1  of the coil board  250 .  FIG. 25B  illustrates a conductive adhesive member  80  connecting the terminal Q 1  of the coil board  231  to the pad  25 - 1  of the circuit board  250  shown in  FIG. 25A . 
     In  FIGS. 24 to 25B , the description of the terminal Q 1  of the coil board  231  and the pad (for example,  25 - 1 ) of the circuit board  250  may also be applied to the remaining terminals Q 2  to Q 8  of the coil board  231  and the remaining pads  25 - 2  to  25 - 4  of the circuit board  250 . 
     Referring to  FIGS. 24 to 25B , the terminal (for example, Q 1 ) of the coil board  231  may be formed so as to overlap the cutting line  51 . When the coil board  231  is cut along the cutting line  51  so as to form the bore, the lateral surface  40   b  of the terminal (for example, Q 1 ) may be exposed at the inner circumferential surface  41  of the coil board  231 , and the exposed lateral surface  40   b  of the terminal (for example, Q 1 ) may become the same surface as the inner circumferential surface  41  of the coil board  231 , with the result that burrs are not formed by laser cutting and it is thus possible to prevent poor conductive contact between the terminal (for example, Q 1 ) of the coil board  231  and the pad (for example,  25 - 1 ) of the circuit board  250 . 
     Furthermore, since the lateral surface  40   b  of the terminal Q 1  of the coil board  231  is exposed at the inner circumferential surface  41  of the coil board  231 , a conductive adhesive member or solder  80  may be disposed at the exposed lateral surface  40   b  of the terminal Q 1 , and the contact area between the conductive adhesive member or solder  80  and the terminal Q 1  of the coil board  231  may be increased, thereby improving solderability. 
     The circuit board  250  may include the bore  25   a  in the circuit board  250   250  and the pad (for example,  25 - 1 ), which abuts on the inner circumferential surface  26   a  of the circuit board  250  and is formed at a position corresponding to the terminal (for example, Q 1 ) of the coil board  231 . 
     The size or diameter of the bore  231   a  in the coil board  231  may be smaller than the size or diameter of the bore  25   a  in the circuit board  250 . 
     For example, the inner circumferential surface  26   a  of the circuit board  250  may be positioned outside the inner circumferential surface  41  of the coil board  231 . 
     For example, although the distance between the inner circumferential surface  26   a  of the circuit board  250  and the inner circumferential surface  41  of the coil board  231  may be less than the thickness of the circuit board  250 , the disclosure is not limited thereto. In another embodiment, the distance between the inner circumferential surface  26   a  of the circuit board  250  and the inner circumferential surface  41  of the coil board  231  may be equal to or greater than the thickness of the circuit board  250 . 
     For example, although the distance between the inner circumferential surface  26   a  of the circuit board  250  and the inner circumferential surface  41  of the coil board  231  may be greater than the thickness of the coil board  231 , the disclosure is not limited thereto. In another embodiment, the distance between the inner circumferential surface  26   a  of the circuit board  250  and the inner circumferential surface  41  of the coil board  231  may be equal to or less than the thickness of the coil board  231 . 
     For example, the pad  25 - 1  of the circuit board  250  may have a lateral surface  59   c  that is exposed at the inner circumferential surface  26   a  of the circuit board  250 . For example, the pad  25 - 1  of the circuit board  250  may have a lateral surface  59   c  that is exposed toward the center of the bore  25   a  in the circuit board  250 . 
     For example, the pad (for example,  25 - 1 ) of the circuit board  250  may be exposed at at least one of the upper surface, the lateral surface and the lower surface of the circuit board  250 . 
     For example, the pad (for example,  25 - 1 ) of the circuit board  250  may include a first portion  59   a  (see  FIG. 18 ), which is exposed at the upper surface of the circuit board  250 , a second portion  59   b  (see  FIG. 25A ), which is exposed at the lower surface of the circuit board  260 , and a third portion  59   c , connecting the first portion  59   a  to the second portion  59   b . Although the pad of the circuit board  250  may be a conductive layer, for example, an Au layer or an Au-plated layer, the disclosure is not limited thereto. 
     The third portion  59   c  of the pad  25 - 1  of the circuit board  250  may be provided at the inner circumferential surface of the circuit board  250 . In order to increase the contact area with solder, the third portion  59   c  of the circuit board  250  may have a recess shape or a groove shape depressed from the inner circumferential surface of the circuit board  250 . 
     Although the third portion  59   c  of the pad  25 - 1  of the circuit board  250  may have a curved surface, for example, a semicircular via shape, the disclosure is not limited thereto. 
     For example, a groove may be formed in the inner circumferential surface  26   a  of the circuit board  250 , and the pad  25 - 1  of the circuit board  250  may include the third portion  59   c , which is formed in the groove in the circuit board  250 . 
     Although the curvature radius of the curved surface (or the groove in the circuit board  250 ) of the third portion  59   c  of the pad  25 - 1  of the circuit board  250  may be less than the curvature radius of the inner circumferential surface  41  of the bore  231   a  in the coil board  231 , the disclosure is not limited thereto. In another embodiment, the curvature radius of the curved surface of the third portion  59   c  may be equal to or greater than the curvature radius of the inner circumferential surface  41  of the bore  231   a.    
     Although the length K 1  of the second portion  59   b  of the pad  25 - 1  of the circuit board  250  may be equal to the length K 2  of the terminal Q 1  of the coil board  231  (K 1 =K 2 ), the disclosure is not limited thereto. In another embodiment, the length K 1  may be greater than the length K 2  (K 1 &gt;K 2 ). In a further embodiment, the length K 1  may be less than the length K 2  (K 1 &lt;K 2 ). 
     Here, the length K 1  may be the shortest distance between the two ends of the second portion  59   b  abutting on the inner circumferential surface  41  of the circuit board  250  or the diameter of the second portion  59   b  of the circuit board  250 . The length K 2  may be the distance between the two ends of the terminal Q 1  abutting on the inner circumferential surface  41  of the coil board  231 . 
     For example, the length K 1  may be 0.4 mm-1.6 mm, and the length K 2  may be 0.4 mm-2 mm. For example, the diameter of the third portion  59   c  of the pad  25 - 1  of the circuit board  250  may be 0.3 mm-0.6 mm. 
     Although the thickness T 3  of the pad  25 - 1  of the circuit board  250  may be 100 μm-140 μm, the disclosure is not limited thereto. Although the thickness of the terminal Q 1  of the coil board  231  may be 40 μm-60 μm, the disclosure is not limited thereto. 
     The thickness T 3  of the pad  25 - 1  of the circuit board  250  may be less than the length K 1  of the pad  25 - 1  of the circuit board  250  (T 3 &lt;K 1 ). 
     For example, the ratio of the thickness T 3  of the pad  25 - 1  to the length K 1  of the pad  25 - 1  of the circuit board  250  (T 3 :K 1 ) may be 1:2.5-1:6. 
     Although the length of the first portion  59   a  of the pad  25 - 1  of the circuit board  250  may be equal to the length K 2  of the terminal Q 1  of the coil board  231 , the disclosure is not limited thereto. In another embodiment, the length of the first portion  59   a  may be greater or less than the length K 2  of the terminal Q 1  of the coil board  231 . 
     Although the length of the first portion  59   a  of the pad  25 - 1  of the circuit board  250  may be equal to the length K 1 , the disclosure is not limited thereto. 
     For example, the pad (for example,  25 - 1 ) of the circuit board  250  may overlap at least a portion of the terminal (for example, Q 1 ) of the coil board  231  in the optical-axis direction. 
     The conductive adhesive member  80  may be in contact with or coupled or attached to the exposed lateral surface  59   c  of the pad  25 - 1  of the circuit board  250 . Furthermore, the conductive adhesive member  80  may be in contact with or coupled or attached to the exposed lateral surface  40   b  of the terminal  25 - 1  of the coil board  231 . 
     The conductive adhesive member or solder  80  may be disposed on, in contact with, coupled to, or attached to at least one of the first to third portions  59   a  to  59   c  of the pad (for example,  25 - 1 ) of the circuit board  250  and to the terminal (for example, Q 1 ) of the coil board  231 . 
     The coil board  231  may include a dummy layer, a dummy pattern or a dummy line  45  in order to increase durability. 
     Generally, in the case in which the cover layer of the coil board  231  is formed of a resin such as epoxy, burrs may be generated at the cut surface in a cutting operation for formation of the bore or the unit coil board, and foreign substances caused by the burrs may thus be generated. 
     Furthermore, because the resin layer such as the epoxy layer is easily scratched, foreign substances may be generated due to an impact or scratching during handling of the coil board  231 , and the foreign substances may cause malfunction of the lens moving apparatus or deterioration in the image quality of the image sensor of the camera module. 
     As illustrated in  FIG. 22 , since each of the first insulation layer  71  and the third insulation layer  75  of the second coil  230  includes the polyimide layer  7   b   1  or  7   b   2  on the surface of the resin layer  7   a   1  or  7   a   2  thereof, the embodiment is able to suppress the generation of contaminants at the coil board  231  caused by cutting, impact or scratch. 
     The lens moving apparatuses  100  according to the above-described embodiments may be embodied as or used in, for example, a camera module or an optical device in various fields. 
     For example, the lens moving apparatus  100  according to the embodiment may be included in an optical instrument, which is designed to form an image of an object in a space using reflection, refraction, absorption, interference, diffraction or the like, which are characteristics of light, to extend eyesight, to record an image obtained through a lens or reproduce the image, to perform optical measurement, or to propagate or transmit an image. For example, the optical instrument according to the embodiment may be a smart phone or a portable terminal equipped with a camera.
