Hereinafter, a lighting apparatus according to embodiments will be described with reference to the accompanying drawings. 
     Hereinafter, a lens moving apparatus according to an embodiment will be described with reference to the accompanying drawings. For the convenience of description, although the lens moving apparatus will be described using a rectangular coordinate system (x, y, z), the lens moving apparatus may be described using other coordinate systems, and the embodiment is not limited thereto. In the respective drawings, the X-axis and the Y-axis mean directions perpendicular to an optical axis, i.e. the Z-axis, and the optical axis (Z-axis) direction may be referred to as a “first direction”, the X-axis direction may be referred to as a “second direction”, and the Y-axis direction may be referred to as a “third direction”. 
     A “hand tremor compensation device”, which is applied to a subminiature camera module of a mobile device such as, for example, a smart phone or a tablet PC, may be a device that is configured to inhibit the contour line of a captured image from not being clearly formed due to vibration caused by the user&#39;s hand tremor when capturing a still image. 
     In addition, an “auto-focusing device” is a device that automatically focuses an image of a subject on an image sensor surface. The hand tremor compensation device and the auto-focusing device may be configured in various ways, and the lens moving apparatus according to the embodiment may move an optical module, which is constituted of at least one lens, in the first direction, or relative to a plane defined by the second and third directions, thereby performing hand tremor compensation motion and/or auto-focusing. 
       FIG. 1  is a schematic perspective view illustrating the lens moving apparatus  100  according to an embodiment, and  FIG. 2  is an exploded perspective view of the lens moving apparatus  100  illustrated in  FIG. 1 . 
     Referring to  FIGS. 1 and 2 , the lens moving apparatus  100  may include a cover member  300 , an upper elastic member  150 , a sensor board  180 , a first position sensor  170 , a first coil  120 , a bobbin  110 , a housing  140 , a magnet  130 , a lower elastic member  160 , a plurality of support members  220 , a second coil  230 , a circuit board  250 , a second position sensor  240 , and a base  210 . 
     First, the cover member  300  will be described. 
     The cover member  300  defines an accommodation space along with the base  210 , such that the upper elastic member  150 , the bobbin  110 , the first coil  120 , the housing  140 , the magnet  130 , the lower elastic member  160 , the support members  220 , the second coil  230 , and the circuit board  250  are accommodated in the accommodation space. 
     The cover member  300  may take the form of a box, which has an open bottom and includes an upper end portion and sidewalls. The bottom of the cover member  300  may be coupled to the top of the base  210 . The upper end portion of the cover member  300  may have a polygonal shape such as, for example, a square or octagonal shape. 
     The cover member  300  may have a bore formed in the upper end portion thereof in order to expose a lens (not illustrated) coupled to the bobbin  110  to outside light. In addition, the bore of the cover member  300  may be provided with a window formed of a light-transmitting material, in order to inhibit impurities, such as, for example, dust or moisture, from entering a camera module. 
     Although the material of the cover member  300  may be a non-magnetic material such as, for example, SUS in order to inhibit the cover member  300  from being attracted by the magnet  130 , the cover member  300  may be formed of a magnetic material and may function as a yoke. 
       FIG. 3  is an assembled perspective view illustrating the lens moving apparatus  100  after removal of the cover member  300  of  FIG. 1 , and  FIG. 4  is an exploded perspective view of the bobbin  110 , the first coil  120 , the magnet  130 , the first position sensor  170 , and the sensor board  180  illustrated in  FIG. 2 . 
     Next, the bobbin  110  will be described. 
     Referring to  FIGS. 3 and 4 , the bobbin  110  is placed inside the housing  140 , which will be described below, and is movable in the first direction, for example, in the Z-axis via electromagnetic interaction between the first coil  120  and the magnet  130 . 
     Although not illustrated, the bobbin  110  may include a lens barrel (not illustrated) in which at least one lens is installed. The lens barrel may be coupled inside the bobbin  110  in various manners. 
     For example, the bobbin  110  may be configured to have a bore for the mounting of the lens or the lens barrel. The bore may have a circular, elliptical, or polygonal shape, without being limited thereto. 
     The bobbin  110  may include first and second protrusions  111  and  112 . 
     The first protrusion  111  of the bobbin  110  may include a guide portion  111   a  and a first stopper  111   b.    
     The guide portion  111   a  of the bobbin  110  may serve to guide an installation position of the upper elastic member  150 . For example, as exemplarily illustrated in  FIG. 3 , the guide portion  111   a  of the bobbin  110  may guide a first frame connection portion  153  of the upper elastic member  150 . 
     The second protrusion  112  of the bobbin  110  may be formed on an outer circumferential surface  110   b  of the bobbin  110  so as to protrude in the second and third directions, which are perpendicular to the first direction. In addition, the second protrusion  112  of the bobbin  110  may be provided on an upper surface  112   a  thereof with a first coupling boss  113   a , which is coupled to a first inner frame  151  of the upper elastic member  150 , which will be described below. 
     The first stopper  111   b  of the first protrusion  111  and the second protrusion  112  of the bobbin  110  may serve to inhibit the bottom surface of the body of the bobbin  110  from directly colliding with the base  210  and the upper surface of the circuit board  250  even if the bobbin  110  moves beyond a prescribed range due to, for example, external shock when being moved in the optical axis direction or in the first direction, which is parallel to the optical axis, for auto-focusing. 
     To this end, the first stopper  111   b  of the bobbin  110  may far protrude in the second or third direction, which is the circumferential direction, from the outer circumferential surface  110   b  of the bobbin  110  than the guide portion  111   a  of the bobbin  110 . In addition, the second protrusion  112  of the bobbin  110  may far protrude laterally than the upper surface  112   a  on which the upper elastic member  150  is seated. 
     The bobbin  110  may have a support groove  114  provided between an inner circumferential surface  110   a  and the outer circumferential surface  110   b  of the bobbin  110  so as to allow the sensor board  180  to be inserted into the bobbin  110  in the first direction. For example, the support groove  114  of the bobbin  110  may be provided between the inner circumferential surface  110   a  of the bobbin  110  and the first and second protrusions  111  and  112  so as to enable the insertion of the sensor board  180 . 
     The bobbin  110  may have a receiving recess  116 , which is suitable to receive the first position sensor  170  disposed, coupled, or mounted on the sensor board  180 . 
     For example, the receiving recess  116  of the bobbin  110  may be provided in the space between the first and second protrusions  111  and  112  of the bobbin  110 , so as to allow the first position sensor  170  mounted on the sensor board  180  to be inserted in the first direction. 
     The bobbin  110  may have a second coupling boss  117  (see  FIG. 9 ) formed on the lower surface thereof so as to be coupled and fixed to the lower elastic member  160 . 
     When the position at which the lower surfaces of the first and second protrusions  111  and  112  of the bobbin  110  come into contact with a bottom surface  146   a  of a first seating groove  146  of the housing  140  is set to an initial position, auto-focusing may be controlled so as to be performed in a single direction. That is, auto-focusing may be implemented such that the bobbin  110  moves upward when current is supplied to the first coil  120 , and moves downward when the supply of current is interrupted. 
     However, when the position at which the lower surfaces of the first and second protrusions  111  and  112  of the bobbin  110  are spaced apart from the bottom surface  146   a  of the first seating groove  146  by a given distance is set to an initial position, auto-focusing may be controlled so as to be performed in two directions. For example, auto-focusing may be implemented such that the bobbin  110  moves upward when forward current is applied to the first coil  120  and moves downward when reverse current is applied to the first coil  120 . 
     Next, the first coil  120  will be described. 
     The first coil  120  is disposed on the outer circumferential surface  110   b  of the bobbin  110 . 
     The first coil  120  may be located so as not to overlap the first position sensor  170  in the direction perpendicular to the optical axis, for example, in the X-axis or the Y-axis. 
     For example, in order to ensure that the first coil  120  and the first position sensor  170  do not interfere or overlap each other in the direction perpendicular to the optical axis, the first position sensor  170  may be located on the upper portion of the outer circumferential surface  110   b  of the bobbin  110 , and the first coil  120  may be located on the lower portion of the outer circumferential surface  110   b  of the bobbin  110 . 
     The first coil  120 , as exemplarily illustrated in  FIG. 4 , may be wound so as to surround the outer circumferential surface  110   b  of the bobbin  110  in the direction in which the first coil  120  rotates about the optical axis. For example, the first coil  120  may be inserted into and coupled to a coil groove formed in the outer circumferential surface  110   b  of the bobbin  110 , without being limited thereto. 
     As exemplarily illustrated in  FIG. 4 , the first coil  120  may be directly wound around the outer circumferential surface  110   b  of the bobbin  110 . In another embodiment, the first coil  120  may take the form of an angled ring-shaped coil block, without being limited thereto. 
     The first coil  120  may produce electromagnetic force via interaction with the magnet  130  when current is supplied thereto, thereby moving the bobbin  110  in the first direction using the electromagnetic force. The first coil  120  may be disposed so as to correspond to or face the magnet  130 . 
     Next, the first position sensor  170  and the sensor board  180  will be described. 
     The first position sensor  170  may be disposed, coupled, or mounted on the bobbin  110 , so as to move along with the bobbin  110 . The first position sensor  170  may move along with the bobbin  110  when the bobbin  110  moves in the first direction. 
     The first position sensor  170  may sense the strength of a magnetic field of the magnet  130  depending on the movement of the bobbin  110 , and may output a signal based on the sensed result. 
     The first position sensor  170  may be electrically connected to the sensor board  180 . The first position sensor  170  may take the form of a driver including a Hall sensor, or may take the form of a position detection sensor alone such as, for example, a Hall sensor. 
     The first position sensor  170  may be disposed, coupled, or mounted on the bobbin  110  in various forms, and may receive current in various ways depending on the form in which the first position sensor  170  is disposed, coupled, or mounted. 
     The first position sensor  170  may be disposed, coupled, or mounted on the outer circumferential surface  110   b  of the bobbin  110 . For example, the first position sensor  170  may be disposed, coupled, or mounted on the sensor board  180 , and the sensor board  180  may be coupled to the bobbin  110 . 
     The first position sensor  170  may be electrically connected to at least one of the upper elastic member  150  and the lower elastic member  160 . For example, the first position sensor  170  may be electrically connected to the upper elastic member  150 . 
     The sensor board  180  may be mounted on the bobbin  110 , and may move along with the bobbin  110  in the optical axis direction or in the direction parallel to the optical axis. For example, the sensor board  180  may be inserted into the support groove  114  of the bobbin  110  and coupled to the bobbin  110 . The sensor board  180  is sufficient so long as it is mounted on the bobbin  110 , and  FIG. 4  illustrates the sensor board  180  having a ring shape, without being limited thereto. 
     The first position sensor  170  may be attached to and supported by the front surface of the sensor board  180  using an adhesive member such as, for example, a double-sided tape, or epoxy. 
     The outer circumferential surface  110   b  of the bobbin  110  may be comprised of first side surfaces  110   b - 1  and second side surfaces  110   b - 2 . The first side surfaces  110   b - 1  correspond to first side portions  141  of the housing  140  on which the magnet  130  is disposed. The second side surfaces  110   b - 2  are located between the first side surfaces  110   b - 1  so as to connect the first side surfaces  110   b - 1  to one another. 
     The first position sensor  170  may be disposed on any one of the first side surfaces  110   b - 1  of the bobbin  110 . For example, the receiving recess  116  of the bobbin  110  may be provided at any one of the first side surfaces  110   b - 1  of the bobbin  110 , and the first position sensor  170  may be located in the receiving recess  116  of the bobbin  110 . 
     The first position sensor  170  may be disposed, coupled, or mounted on an upper portion A 1 , a middle portion A 2 , or a lower portion A 3  of the outer circumferential surface of the sensor board  180  in various forms. At this time, the first position sensor  170  may receive current from the outside through a circuit of the sensor board  180 . 
     The sensor board  180  may include a body  182 , elastic member contact portions  184 - 1  to  184 - 4 , and a circuit pattern. 
     The body  182  of the sensor board  180  may include a first segment  182   a  on which the first position sensor  170  is disposed, coupled, or mounted, and a second segment  182   b  connected to the first segment  182   b  and configured so as to be inserted into the support groove  114  of the bobbin  110 . The elastic member contact portions  184 - 1  to  184 - 4  may be provided on the second segment  182   b.    
     For example, in order to allow the sensor board  180  to be easily inserted into the support groove  114  of the bobbin  110 , the second segment  182   b  of the sensor board  180  may be provided with an opening  181 . 
     The elastic member contact portions  184 - 1  to  184 - 4  of the sensor board  180  may be connected to the first inner frame  151  of the upper elastic member  150 . 
     The circuit pattern of the sensor board  180  may be formed on the body  182  of the sensor board  180 , and may electrically connect the first position sensor  170  and the elastic member contact portions  184 - 1  to  184 - 4  to each other. 
     For example, in order to increase the distance between the first position sensor  170  and the first coil  120 , the first position sensor  170  may be disposed, coupled, or mounted on the upper portion of the outer circumferential surface of the sensor board  180 . This serves to inhibit the malfunction and errors of the first position sensor  170  by inhibiting the first position sensor  170  from being affected by the magnetic field of the first coil  120  within a high frequency range. 
     At least a portion of the first position sensor  170  may overlap the magnet  130  in the direction perpendicular to the optical axis, without being limited thereto. 
     A lens moving apparatus in accordance with another embodiment may further include a separate sensing magnet for the first position sensor  170 . The separate sensing magnet may be mounted on the bobbin  110  or the housing  140 . At this time, at least a portion of the first position sensor  170  may overlap the sensing magnet in the direction perpendicular to the optical axis, rather than overlapping the magnet  130 . 
     Next, the housing  140  will be described. 
     The housing  140  may support the magnet  130 , and may accommodate the bobbin  110  therein so as to allow the bobbin  110  to move in the first direction, which is parallel to the optical axis. 
     The housing  140  may generally have a hollow column shape. For example, the housing  140  may have a polygonal (e.g., a square or octagonal) or circular bore. 
       FIG. 5  is a perspective view of the housing  140  illustrated in  FIG. 2 ,  FIG. 6  is a bottom perspective view of the housing  140  illustrated in  FIG. 2 ,  FIG. 7  is a sectional view taken along line I-I′ of  FIG. 3 ,  FIG. 8  is a perspective view illustrating the coupled state of the bobbin  110 , the housing  140 , the upper elastic member  150 , the first position sensor  170 , the sensor board  180 , and the support members  220  illustrated in  FIG. 2 , and  FIG. 9  is a bottom perspective view illustrating the coupled state of the bobbin  110 , the housing  140 , the lower elastic member  160 , and the support members  220  illustrated in  FIG. 2 . 
     The housing  140  may have the first seating groove  146  formed at a position thereof corresponding to the first and second protrusions  111  and  112  of the bobbin  110 . 
     The housing  140  may have a third protrusion  148 , which corresponds to each of the second side surfaces  110   b - 2  of the bobbin  110 . The third protrusion  148  of the housing  140  may inhibit the bobbin  110  from being rotated even if the bobbin  110  receives force in the direction in which the bobbin  110  is rotated about the optical axis, rather than being rotated in the optical axis direction. 
     For example, the upper edge of the outer periphery of the housing  140  may have a square plan shape, whereas the lower edge of the inner periphery may have an octagonal plan shape, as exemplarily illustrated in  FIGS. 5 and 6 . The housing  140  may include a plurality of side portions. For example, the housing  140  may include four first side portions  141  and four second side portions  142 . 
     The magnet  130  may be mounted on the first side portions  141  of the housing  140 . The second side portions  142  of the housing  140  may be located respectively between the two neighboring first side portions  141 . The support members  220  may be disposed on the second side portions  142  of the housing  140 . The first side portions  141  of the housing  140  may interconnect the second side portions  142  of the housing  140 . 
     The housing  140  may have magnet seats  141   a  provided on inner surfaces of the first side portions  141  in order to accommodate magnets  130 - 1  to  130 - 4 . Each of the magnets  130 - 1  to  130 - 4  may be fixed to the magnet seat  141   a , which is provided on a corresponding one of the first side portions  141  of the housing  140 . 
     The magnet seat  141   a  of the housing  140  may be configured as a groove having a size corresponding to the size of the magnet  130 . An aperture may be formed in the bottom surface of the magnet seat  141   a  of the housing  140 . The lower surface of the magnet  130  fixed to the magnet seat  141   a  may face the second coil  230 . 
     The magnet  130  may be secured to the magnet seat  141   a  of the housing  140  using an adhesive, without being limited thereto, and for example, an adhesive member such as a double-sided tape may be used. 
     Alternatively, the magnet seat  141   a  of the housing  140  may be configured as a mounting hole, which allows a portion of the magnet  130  to be fitted thereinto or to be exposed therefrom, rather than being configured as the groove illustrated in  FIG. 6 . 
     The first side portion  141  of the housing  140  may be oriented parallel to the side surface of the cover member  300 . In addition, the first side portion  141  of the housing  140  may be larger than the second side portion  142 . The second side portion  142  of the housing  140  may be provided with first through-holes  147   a  and  147   b , through which the support members  220  pass. 
     In addition, in order to inhibit the housing  140  from directly colliding with the inner side surface of the cover member  300  illustrated in  FIG. 1 , the housing  140  may be provided at the upper end thereof with a second stopper  144 . 
     The housing  140  may have at least one first upper support boss  143  formed on the upper surface thereof for the coupling of the upper elastic member  150 . 
     For example, the first upper support boss  143  of the housing  140  may be formed on the upper surface of the housing  140  corresponding to the second side portion  142  of the housing  140 . The first upper support boss  143  of the housing  140  may have a semispherical shape, cylindrical shape or prism shape, without being limited thereto. 
     The housing  140  may have second a lower support boss  145  formed on the lower surface thereof for the coupling and fixing of the lower elastic member  160 . 
     In order to define paths for the passage of the support members  220  and to ensure the space to be filled with silicon, which serves as a damper, the housing  140  may have a first recess  142   a  formed in the second side portion  142 . 
     The housing  140  may have a plurality of third stoppers  149  protruding from the side surface thereof. The third stoppers  149  serve to inhibit the housing  140  from colliding with the cover member  300  when the housing  140  moves in the second and third directions. 
     In order to inhibit the lower surface of the housing  140  from colliding with the base  210  and/or the circuit board  250  which will be described below, the housing  140  may further have a fourth stopper (not illustrated) protruding from the lower surface thereof. Through this configuration, the housing  140  may be downwardly spaced apart from the base  210  and may be upwardly spaced apart from the cover member  300 . In this way, the housing  140  may perform hand tremor compensation in the direction perpendicular to the optical axis. 
     The magnet  130  may be accommodated inside the first side portion  141  of the housing  140 , without being limited thereto. In another embodiment, the magnet  130  may be disposed outside the first side portion  141  of the housing  140 , or may be disposed inside or outside the second side portion  142  of the housing  140 . 
     Next, the magnet  130  will be described. 
     Each of the magnets  130 - 1  to  130 - 4  may be configured as a single body, and may be a unipolar magnet, the inner side and the outer side of which have different polarities. 
     For example, the magnets  130 - 1  to  130 - 4  may be disposed such that the boundary between an S-pole and an N-pole of each magnet is parallel to the direction perpendicular to the direction in which the magnet  130  and the first coil  120  face each other. 
     For example, although each of the magnets  130 - 1  to  130 - 4  may be oriented such that the surface thereof facing the first coil  120  is the S-pole  132  and the opposite surface is the N-pole  134 , the embodiment is not limited thereto, and the opposite configuration is also possible. 
     At least two or more magnets  130  may be installed, and in the embodiment, four magnets  130  may be installed. The shape of the magnet  130  may correspond to the shape of the first side portion  141  of the housing  140 , without being limited thereto. For example, the magnet  130  may have a rectangular shape, without being limited thereto, and the magnet  130  may have a triangular or diamond shape based on the position thereof on the housing  140 . 
     Although the surface of the magnet  130  facing the first coil  120  may be flat, the embodiment is not limited thereto. The surface of the magnet  130  facing the first coil  120  may be curved. 
     One pair of magnets  130 - 2  and  130 - 4  among the magnets  130 - 1  to  130 - 4  may be arranged parallel to each other in the second direction (in the X-axis), and the other pair of magnets  130 - 1  and  130 - 3  may be arranged parallel to each other in the third direction (in the Y-axis). 
     In another embodiment, the magnet  130  may be a bipolar magnet. At this time, the kinds of bipolar magnets may be broadly divided into ferrite, alnico, and rare-earth magnets, for example, and may be sorted into a P-type and an F-type according to the form of a magnetic circuit. The embodiment is not limited as to the kinds of bipolar magnets. 
     Next, the upper elastic member  150 , the lower elastic member  160 , and the support members  220  will be described. 
     The upper elastic member  150  and the lower elastic member  160  elastically support the bobbin  110 . The support members  220  may support the housing  140  so as to be movable relative to the base  210  in the direction perpendicular to the optical axis, and may electrically connect at least one of the upper and lower elastic members  150  and  160  to the circuit board  250 . 
       FIG. 11  is an assembled perspective view illustrating the upper elastic member  150 , the lower elastic member  160 , the first position sensor  170 , the sensor board  180 , the base  210 , the support members  220 , and the circuit board  250  illustrated in  FIG. 2 . 
     The upper elastic member  150  may include a plurality of upper elastic members  150 - 1  to  150 - 4  (and  150 - 5  and  150 - 6 ), which are electrically separated from one another. 
     For example, the separate upper elastic members  150 - 1  to  150 - 4  (and 150-5 and 150-6) may be point symmetrical to one another in the X-Y plane on the basis of the center of the bobbin  110 . Here, “point symmetry” refers to symmetry in which two forms overlap each other when the two forms are rotated by 180 degrees about a single rotation center point. 
     The elastic member contact portions  184 - 1  to  184 - 4  of the sensor board  180  may be electrically connected to at least one of the upper elastic member  150  and the lower elastic member  160 . 
       FIG. 11  illustrates that the elastic member contact portions  184 - 1  to  184 - 4  of the sensor board  180  come into electrical contact with the upper elastic members  150 - 1  to  150 - 4 , without being limited thereto. In another embodiment, the elastic member contact portions  184 - 1  to  184 - 4  of the sensor board  180  may come into electrical contact with the lower elastic member  160 , or may come into electrical contact with both the upper elastic member  150  and the lower elastic member  160 . 
     The respective elastic member contact portions  184 - 1  to  184 - 4  of the sensor board  180 , which are electrically connected to the first position sensor  170 , may be electrically connected to a corresponding one of the upper elastic members  150 - 1  to  150 - 4 . In addition, the respective upper elastic members  150 - 1  to  150 - 4  may be electrically connected to a corresponding one of the support members  220 - 1  to  220 - 4 . 
     Each one  150   a  of the first and third upper elastic members  150 - 1  and  150 - 3  may include a first inner frame  151 , a first-first outer frame  152   a , and a first frame connection portion  153 . 
     Each one  150   b  of the second and fourth upper elastic members  150 - 2  and  150 - 4  may include the first inner frame  151 , a first-second outer frame  152   b , and the first frame connection portion  153 . 
     The first inner frame  151  of each of the upper elastic members  150 - 1  to  150 - 4  may be coupled or fixed to the bobbin  110 . For example, the first coupling boss  113   a  of the bobbin  110  may be inserted into a second-first through-hole  151   a  formed in the first inner frame  151  of each of the upper elastic members  150 - 1  to  150 - 4 , and then both the first coupling boss  113   a  and the second-first through-hole  151   a  may be fixed to each other via thermal bonding, or using an adhesive such as, for example, epoxy. The first inner frame  151  of each of the upper elastic members  150 - 1  to  150 - 4  may be electrically connected to a corresponding one of the elastic member contact portions  184 - 1  to  184 - 4  of the sensor board  180 . 
     The first-first and first-second outer frames  152   a  and  152   b  of the upper elastic members  150 - 1  to  150 - 4  may be coupled to the housing  140  and may be connected to the support members  220 . 
     The first frame connection portion  153  of each of the upper elastic members  150 - 1  to  150 - 4  may connect the first inner frame  151  to the first-first outer frame  152   a  or the first-second outer frame  152   b . Although the first-second outer frame  152   b  may be formed by bisecting the first-first outer frame  152   a , the embodiment is not limited thereto. In another embodiment, the first-first outer frame  152   a  may be bisected, and each part of the bisected first-first outer frame  152   a  may have the same shape as or may be symmetrical to the first-second outer frame  152   b.    
     The first frame connection portion  153  of each of the upper elastic members  150 - 1  to  150 - 4  may be bent at least one time so as to form a given pattern. Upward and/or downward movement of the bobbin  110  in the first direction may be elastically supported via position variation and fine deformation of the first frame connection portion  153  of each of the upper elastic members  150 - 1  to  150 - 4 . 
     The first-first or first-second outer frame  152   a  or  152   b  of the upper elastic member  150  illustrated in  FIG. 11  may be coupled and fixed to the first upper support boss  143  of the housing  140 . 
     In the embodiment, each of the first-first and first-second outer frames  152   a  and  152   b  may be formed with a second-second through-hole  157 , which has a shape and position corresponding to those of the first upper support boss  143 . At this time, the first upper support boss  143  and the second-second through-hole  157  may be fixed to each other via thermal bonding, or using an adhesive such as, for example, epoxy. 
     After the first inner frames  151  are coupled to the bobbin  110  and the first-first and first-second outer frames  152   a  and  152   b  are coupled to the housing  140 , conductive connections CP 11 , CP 12 , CP 13  and CP 14  are performed on the elastic member contact portions  184 - 1  to  184 - 4  of the sensor board  180  and the first inner frames  151  using such as, for example, solders or conductive epoxy, as illustrated in  FIG. 8 . 
     Through the conductive connections CP 11 , CP 12 , CP 13  and CP 14 , (+) power and (−) power may be applied to the first position sensor  170 , and the first position sensor  170  may output a positive (+) output signal or negative (−) output signal. In addition, in order to enable the first position sensor  170  to receive (+) power and (−) power from the circuit board  250  and to output a positive (+) output signal or negative (−) output signal to the circuit board  250 , the upper elastic member  150  may be divided into the first to fourth upper elastic members  150 - 1  to  150 - 4 . 
     The respective first to fourth upper elastic members  150 - 1  to  150 - 4  may be connected to the circuit board  250  via the support members  220 - 1  to  220 - 4 . That is, each of the first to fourth upper elastic members  150 - 1  to  150 - 4  may be electrically connected to the circuit board  250  via at least one of the support members  220 - 1  to  220 - 4 . 
     For example, the first upper elastic member  150 - 1  may be electrically connected to the circuit board  250  via at least one of first-first and first-second support members  220 - 1   a  and  220 - 1   b.    
     The second upper elastic member  150 - 2  may be electrically connected to the circuit board  250  via a second support member  220 - 2 . The third upper elastic member  150 - 3  may be electrically connected to the circuit board  250  via at least one of third-first and third-second support members  220 - 3   a  and  220 - 3   b . The fourth upper elastic member  150 - 4  may be electrically connected to the circuit board  250  via a fourth support member  220 - 4 . In this way, the first position sensor  170  may receive power supplied from the circuit board  250  through the support members  220 - 1  to  220 - 4  and the first to fourth upper elastic members  150 - 1  to  150 - 4 , or may output signals to the circuit board  250 . 
     The support members  220 - 1  to  220 - 4  may be connected to the circuit board  250  through holes  230   a  (see  FIG. 10 ) formed in a circuit member  231 , which will be described below. In another embodiment, no holes may be formed in the circuit member  231  and the circuit board  250 , and the support members  220  may be electrically connected to the circuit member  231  via, for example, soldering. 
     Meanwhile, the lower elastic member  160  may include first and second lower elastic members  160 - 1  and  160 - 2 , which are electrically separated from each other. 
     The first coil  120  may be connected to the support members  220  through the first and second lower elastic members  160 - 1  and  160 - 2 . 
     Each of the first and second lower elastic members  160 - 1  and  160 - 2  may include at least one second inner frame  161 - 1  or  161 - 2 , at least one second outer frame  162 - 1  or  162 - 2 , and at least one second frame connection portion  163 - 1  or  163 - 2 . 
     The second inner frames  161 - 1  and  161 - 2  of the first and second lower elastic members  160 - 1  and  160 - 2  may be coupled to the bobbin  110 , and the second outer frames  162 - 1  and  162 - 2  may be coupled to the housing  140 . 
     The second-first frame connection portion  163 - 1  of the first lower elastic member  160 - 1  may connect the second inner frame  161 - 1  and the second outer frame  162 - 1  to each other, and the second-second frame connection portion  163 - 2  of the second lower elastic member  160 - 2  may connect the second inner frame  161 - 2  and the second outer frame  162 - 2  to each other. 
     Both ends of the first coil  120  may be electrically connected to the first and second lower elastic members  160 - 1  and  160 - 2 . For example, one end of the first coil  120  may be electrically connected to the second inner frame  161 - 1  of the first lower elastic member  160 - 1 , and the other end of the first coil  120  may be electrically connected to the second inner frame  161 - 2  of the second lower elastic member  160 - 2 . The first and second lower elastic members  160 - 1  and  160 - 2  may receive power of different polarities and may transmit the power to the first coil  120 . In order to transmit the power of different polarities to the first coil  120  as described above, the lower elastic member  160  may be bisected into the first and second lower elastic members  160 - 1  and  160 - 2 . 
     At least of the second-first and second-second frame connection portions  163 - 1  and  163 - 2  may be bent at least one time so as to form a given pattern. 
     In addition, the upper elastic member  160  may further include fifth and sixth upper elastic members  150 - 5  and  150 - 6 , which are electrically separated from the first to fourth elastic members  150 - 1  to  150 - 4 . The fifth and sixth upper elastic members  150 - 5  and  150 - 6  may be spaced apart from each other and may be electrically separated from each other. 
     Each of the fifth and sixth upper elastic members  150 - 5  and  150 - 6  may be coupled to the housing  140 , and may be electrically connected to support members  220 - 5  to  220 - 8 . 
     The fifth and sixth upper elastic members  150 - 5  and  150 - 6  may be coupled to only the housing  140  without being coupled to the bobbin  110 , and may elastically support the housing  140 . That is, the fifth and sixth upper elastic members  150 - 5  and  150 - 6  may be spaced apart from the bobbin  110  and may not come into contact with the bobbin  110 . 
     Some support members  220 - 6  and  220 - 8  among the support members  220 - 5  to  220 - 8 , which are coupled to the fifth and sixth upper elastic members  150 - 5  and  150 - 6 , may be connected to the second outer frames  162 - 1  and  162 - 2  of the lower elastic members  160 - 1  and  160 - 2 , and the remaining support members  220 - 5  and  220 - 7  among the support members  220 - 5  to  220 - 8  may be electrically connected to the circuit board  250  through the holes  230   a  formed in the circuit member  231 . 
     For example, the fifth upper elastic member  150 - 5  may be connected to the fifth and sixth support members  220 - 5  and  220 - 6 , and the sixth upper elastic member  150 - 6  may be connected to the seventh and eighth support members  220 - 7  and  220 - 8 . 
     Each of the fifth and sixth upper elastic members  150 - 5  and  150 - 6  may have through-holes for the coupling of the support members  220 - 5  to  220 - 8 , and a through-hole for the coupling of the first upper support boss  143 . 
     The first lower elastic member  160 - 1  may be electrically connected to the circuit board  250  via the sixth support member  220 - 6 , the fifth upper elastic member  150 - 5 , and the fifth support member  220 - 5 . The second lower elastic member  160 - 2  may be electrically connected to the circuit board  250  via the eighth support member  220 - 8 , the sixth upper elastic member  150 - 6 , and the seventh support member  220 - 7 . 
       FIG. 12  is a plan view of the upper elastic member  150  illustrated in  FIG. 2 . 
     Referring to  FIG. 12 , the upper elastic member  150  may include the first to sixth upper elastic members  150 - 1  to  150 - 6 , which are spaced apart from one another. 
     The outer frames  152   a  and  152   b  of the upper elastic members  150  include first coupling portions  510 ,  560  and  570 , which are coupled to the housing  140 , second coupling portions  520   a ,  520   b ,  570   a  and  570   b , which are coupled to the support members  220 - 1  to  220 - 5  and  220 - 7 , and connection portions  530   a ,  530   b ,  580   a  and  580   b , which connect the first coupling portions  510 ,  560  and  570  and the second coupling portions  520   a ,  520   b ,  570   a  and  570   b  to each other. 
     The support members  220 - 1  to  220 - 5  and  220 - 7  may be electrically connected to the second coupling portions  520   a ,  520   b ,  570   a  and  570   b  using, for example, solders or conductive adhesive (e.g. conductive epoxy)  901  (see  FIG. 14A ). For example, one end of the respective support members  220 - 1  to  220 - 5  and  220 - 7  may penetrate the second coupling portions  520   a ,  520   b ,  570   a  and  570   b , and the solders  901  may electrically bond one end of the respective support members  220 - 1  to  220 - 5  and  220 - 7  and the second coupling portions  520   a ,  520   b ,  570   a  and  570   b  to each other. 
     For example, the outer frame  152   a  of each of the first and third upper elastic members  150 - 1  and  150 - 3  may include the first coupling portion  510 , which is coupled to the first upper support bosses  143 - 1  to  143 - 4  (see  FIG. 5 ) of the housing  140 , the second coupling portions  520   a  and  520   b , which are coupled to the support member  220 - 1  or  220 - 3 , and the connection portions  530   a  and  530   b , which connect the first coupling portion  510  and the second coupling portions  520   a  and  520   b  to each other. 
     For example, the outer frame  152   b  of each of the second and fourth upper elastic members  150 - 2  and  150 - 4  may include the first coupling portion  560 , which is coupled to the first upper support bosses  143  of the housing  140 , the second coupling portion  570   a , which is coupled to the support member  220 - 2  or  220 - 4 , and the connection portion  580   a , which connects the first coupling portion  560  and the second coupling portion  570   a  to each other. 
     For example, each of the fifth and sixth upper elastic members  150 - 5  and  150 - 6  may include the first coupling portion  570 , which is coupled to the first upper support bosses  143  of the housing  140 , the second coupling portion  570   b , which is coupled to the support member  220 - 5  or  220 - 7 , the connection portion  580   b , which connects the first coupling portion  570  and the second coupling portion  570   b  to each other, and a third coupling portion  590 , which is connected to the first coupling portion  570  and is coupled to the support member  220 - 6  or  220 - 8 . 
     The support members  220 - 5  and  220 - 7  may be electrically connected to the second coupling portions  570   b  using, for example, solders or conductive adhesive (e.g. conductive epoxy). 
     Each of the first coupling portions  510 ,  560  and  570  of the outer frames  152   a  and  152   b  of the upper elastic members  150  may include two or more coupling regions S 1  to S 4 , S 5  and S 6 , or P 1  and P 2 , which are coupled to the housing  140 . Although the coupling regions S 1  to S 4 , S 5  and S 6 , or P 1  and P 2  are configured as the through-holes  157 , the embodiment is not limited thereto. In another embodiment, the coupling regions S 1  to S 4 , S 5  and S 6 , or P 1  and P 2  may have any of various forms suitable for the coupling of the housing  140 , and for example, may be recesses. 
     For example, although the first coupling portion  510  of the outer frame  152   a  of each of the first and third upper elastic members  150 - 1  and  150 - 3  may include four coupling regions S 1  to S 4  (see  FIG. 14A ), the first coupling portion  560  of the outer frame  152   b  of each of the second and fourth upper elastic members  150 - 2  and  150 - 4  may include two coupling regions S 5  and S 6  (see  FIG. 15A ), and the first coupling portion  570  of each of the fifth and sixth upper elastic members  150 - 5  and  150 - 6  may include two coupling regions P 1  and P 2  (see  FIG. 15A ), the embodiment is not limited as to the number of the coupling regions. 
     The second coupling portions  520   a ,  520   b ,  570   a  and  570   b  of the respective upper elastic members  150 - 1  to  150 - 6  may be connected to any one of the coupling regions S 1  to S 6  and P 1  and P 2  of the first coupling portions  510 ,  560  and  570  via the connection portions  530   a ,  530   b ,  580   a  and  580   b , and may be spaced apart from the remaining coupling regions excluding the aforementioned coupling region. 
     For example, one end of each of the connection portions  530   a ,  530   b ,  580   a  and  580   b  of the upper elastic members  150 - 1  to  150 - 6  may connect any one of the coupling regions S 1  to S 6  and P 1  and P 2  of the first coupling portions  510 ,  560  and  570  and the second coupling portion  520   a ,  520   b ,  570   a  or  570   b  to each other. 
     The connection portion  530   a ,  530   b ,  580   a  or  580   b  of the upper elastic member  150  may be bent at least one time, and a width W 2  of the connection portion  530   a ,  530   b ,  580   a  or  580   b  may be smaller than a width W 1  of the first frame connection portion  153  of the upper elastic member  150 . 
     Because of the width W 2  that is smaller than the width W 1 , the connection portion  530   a ,  530   b ,  580   a  or  580   b  may easily move in the first direction, and consequently, may distribute stress applied to the upper elastic members  150  and stress applied to the support members  220 . 
     Although the width W 1  of the first frame connection portion  153  of the upper elastic member  150  is greater than the width of the second frame connection portion  163 - 1  or  163 - 2  of the lower elastic member  160 , the embodiment is not limited thereto. 
     In another embodiment, the width of the connection portion  530   a ,  530   b ,  580   a  or  580   b  of the upper elastic member  150  may be smaller than the width of the second frame connection portion  163 - 1  or  163 - 2  of the lower elastic member  160 . In this case, the width of the connection portion  530   a ,  530   b ,  580   a  or  580   b  of the upper elastic members  150  may be greater than the width of the first frame connection portion  153  of the upper elastic member  150 , without being limited thereto. 
     In a further embodiment, when the width of the second frame connection portion  163 - 1  or  163 - 2  of the lower elastic member  160  is greater than the width of the connection portion  530   a ,  530   b ,  580   a  or  580   b  of the upper elastic member  150 , the width of the connection portion  530   a ,  530   b ,  580   a  or  580   b  of the upper elastic member  150  may be equal to or smaller than the width of the first frame connection portion  153  of the upper elastic member  150 . 
     For example, the first outer frame  152   a  of each of the upper elastic members  150 - 1  and  150 - 3  may have a left-right symmetric shape about a reference line  501  or  503 . In addition, for example, the remaining portion of each of the fifth and sixth upper elastic members  150 - 5  and  150 - 6  excluding the third coupling portion  590  may be left-right symmetrical to the first outer frame  152   b  of each of the second and fourth upper elastic members  150 - 2  and  150 - 4  about a reference line  502  or  504 , without being limited thereto. 
     The respective reference lines  501  to  504  may be a straight line that passes through the center point ( 101 , see  FIG. 12 ) and a corresponding one of the corners  144 - 1  to  144 - 4  (see  FIG. 5 ) of the housing  140 . Here, the center point  101  may be the center of the bobbin  110  or the center of the housing  140 . 
     For example, in order to maintain balance of the housing  140  so as to inhibit the housing  140  from tilting to one side, the coupling regions S 1  to S 4 , S 5  and S 6 , and P 1  and P 2  of the first coupling portions  510 ,  560  and  570  of the upper elastic members  150  may be left-right symmetrical to one another about the respective reference lines  501  to  504 , without being limited thereto. 
     For example, the first frame connection portions  153  of the first to fourth upper elastic members  150 - 1  to  150 - 4  may be rotation (e.g. 90 degrees rotation) symmetrical to one another about the center point  101  (see  FIG. 12 ). 
     The first coupling regions S 2 , S 3 , S 6  and P 1  may be closer to the reference lines  501  to  504  than the second coupling regions S 1 , S 4 , S 5  and P 2 . Here, among the coupling regions S 1  to S 6  and P 1  and P 2 , the first coupling regions S 2 , S 3 , S 6  and P 1  may be connected to or adjacent to the connection portions  530   a ,  530   b ,  580   a  and  580   b  of the upper elastic members  150 , and the second coupling regions S 1 , S 4 , S 5  and P 2  may be spaced apart from the connection portions  530   a ,  530   b ,  580   a  and  580   b.    
       FIG. 13  is an enlarged view of the first outer frame  152   a  illustrated in  FIG. 12 . 
     Referring to  FIG. 13 , each of the connection portions  530   a  and  530   b  may include a first portion  531   a  or  531   b , which extends in the direction parallel to the reference line  501  or  503 , and a second portion  532   a  or  532   b , which has one end connected to a distal end  13   a  of the first portion  531   a  or  531   b  and the other end connected to the second coupling portion  520   a  or  520   b , the second portion  532   a  or  532   b  being bent at the distal end  13   a  of the first portion  531   a  or  531   b . The shape of the connection portions  580   a  and  580   b  may be the same as the shape of the connection portions  530   a  and  530   b . The first portions  531   a  and  531   b  of the connection portions  530   a  and  530   b  may have a line shape, such as a straight line shape, or a curved line shape having at least one bent portion. 
     For example, the first portions  531   a  and  531   b  of the connection portions  530   a  and  530   b , connected to the first coupling portion  510 , may extend from the center of the bobbin  110  toward the corner of the housing  140 , and the second portions  532   a  and  532   b  of the connection portions  530   a  and  530   b  may be bent from the first portions  531   a  and  531   b  in the direction opposite to the reference line (e.g.  501 ). 
     An internal angle between the first portion  531   a  or  531   b  and the second portion  532   a  or  532   b  may be smaller than 90° but limited thereto. 
     Because the second portions  532   a  and  532   b  of the connection portions  530   a  and  530   b  are bent from the first portions  531   a  and  531   b , the second portions  532   a  and  532   b  may distribute stress applied to the upper elastic member  150  and may inhibit the breakage of the connection portions  530   a  and  530   b.    
     The distance d 1  from the reference lines  501  to  504  to the second coupling portions  520   a ,  520   b ,  570   a  and  570   b  may be greater than the distance d 2  from the reference lines  501  to  504  to the first portions  531   a  and  531   b  of the connection portions  530   a ,  530   b ,  580   a  and  580   b  (d 1 &gt;d 2 ). For example, d 2  may be maximum distance from the reference lines  501  to  504  to the first portions  531   a  and  531   b  of the connection portions  530   a ,  530   b ,  580   a  and  580   b.    
     The first connection portion  530   a  and the second connection portion  530   b  of each of the first and third upper elastic members  150 - 1  and  150 - 3  may be left-right symmetrical to each other about the reference line  501  or  503 , without being limited thereto. 
     The connection portions  580   a  of the second and fourth upper elastic members  150 - 2  and  150 - 4  and the connection portions  580   b  of the fifth and sixth upper elastic members  150 - 5  and  150 - 6  may be left-right symmetrical to each other about the reference line  502  or  504 , without being limited thereto. 
       FIG. 14A  is a first enlarged perspective view of a first portion  8   a  illustrated by a dotted line in  FIG. 8 , and  FIG. 14B  is a second enlarged perspective view of the first portion  8   a  illustrated by the dotted line in  FIG. 8 . 
     Referring to  FIGS. 13, 14A and 14B , each of the first coupling portions  510  of the first and third upper elastic members  150 - 1  and  150 - 3  may include the coupling regions S 1  to S 4 , which are coupled to the housing  140 , and each of the connection portions  530   a  and  530   b  may be connected to any one coupling region S 2  or S 3  of the coupling regions S 1  to S 4 . 
     The second coupling portions  520   a  and  520   b  of the first and third upper elastic members  150 - 1  and  150 - 3  may be spaced apart from the remaining coupling regions S 1  and S 4  excluding the coupling regions S 2  and S 3  connected to or adjacent to the connection portions  530   a  and  530   b . The coupling regions S 1  to S 4  may be left-right symmetrical to one another about the reference line (e.g.  501 ). 
     The support members  220 - 1   a  and  220 - 1   b  may be spaced apart from the housing  140 . For example, the support members  220 - 1   a  and  220 - 1   b  may pass through the first through-holes  147   a  and  147   b  formed in the second side portion  142  of the housing  140 . 
     For example, the first upper support bosses  143 - 1  to  143 - 4  of the housing  140  may be coupled to the through-holes  157  of the first coupling portion  510 , and the first upper support bosses  143 - 1  to  143 - 4  and the through-holes  157  coupled thereto may form the coupling regions S 1  to S 4 . 
     The first coupling portion  510  may come into contact with the upper surface of the housing  140  and may be supported by the upper surface of the housing  140 , whereas the connection portion  530   a  may not be supported by the upper surface of the housing  140 , and the second coupling portion  520   a  and  520   b  may not come into contact with the housing  140  and may be spaced apart from the housing  140 . In addition, the empty space between the connection portion  530   a  and the housing  140  may be filled with a damper (not illustrated). 
     The first coupling portion  510  of each of the first and third upper elastic members  150 - 1  and  150 - 3  may include the first to fourth coupling regions S 1  to S 4 , and the second coupling portion  520  may include a second-first coupling portion  520   a  and a second-second coupling portion  520   b , which are spaced from each other. 
     The connection portions  530   a  and  530   b  of each of the first and third upper elastic members  150 - 1  and  150 - 3  may include a first connection portion  530   a , which connects the second coupling region S 2  and the second-first coupling portion  520   a  to each other, and a second connection portion  530   b , which connects the third coupling region S 3  and the second-second coupling portion  520   b  to each other. 
     The support member  220 - 1   a  may be connected to the second-first coupling portion  520   a , and the support member  220 - 1   b  may be connected to the second-second coupling portion  520   b . Each of the support members  220 - 1   a  and  220 - 1   b  may be electrically be connected to corresponding one of the second-first coupling portion  520   a  and the second-second coupling portion  520   b.    
     For example, the first and second coupling regions S 1  and S 2  may be located at the left side of the reference line (e.g.  501 ), and the third and fourth coupling regions S 3  and S 4  may be located at the right side of the reference line (e.g.  501 ). 
     The distance between each of the second and third coupling regions S 2  and S 3  and the reference line (e.g.  501 ) may be smaller than the distance between each of the first and fourth coupling regions S 1  and S 4  and the reference line (e.g.  501 ). 
     The first coupling portion  510  and the second-first coupling portion  520   a  may realize single contact owing to the first connection portion  530   a , and the first coupling portion  510  and the second-second coupling portion  520   b  may realize single contact owing to the second connection portion  530   b.    
       FIG. 15A  is a first enlarged perspective view of a second portion  8   b  illustrated by a dotted line in  FIG. 8 , and  FIG. 15B  is a second enlarged perspective view of the second portion  8   b  illustrated by the dotted line in  FIG. 8 . 
     Referring to  FIGS. 12, 15A and 15B , the first coupling portion  560  of each of the second and fourth upper elastic members  150 - 2  and  150 - 4  may include the coupling regions S 5  and S 6 , which are coupled to the housing  140 , and the connection portion  580   a  may be connected to any one coupling region S 6  among the coupling regions S 5  and S 6 . 
     The second coupling portion  570   a  of each of the second and fourth upper elastic members  150 - 2  and  150 - 4  may be spaced apart from the remaining coupling region S 5  excluding the coupling region S 6  connected to the connection portion  580   a . The coupling regions S 5  and S 6  may be left-right symmetrical to the coupling regions P 1  and P 2  of the fifth and sixth upper elastic members  150 - 5  and  150 - 6  about the reference line (e.g.  502  or  504 ). 
     The first coupling portion  560  of each of the second and fourth upper elastic members  150 - 2  and  150 - 4  may come into contact with the upper surface of the housing  140  and may be supported by the upper surface of the housing  140 , whereas the connection portion  580   a  may not be supported by the upper surface of the housing  140 , and the second coupling portion  570   a  may not come into contact with the housing  140  and may be spaced apart from the housing  140 . In addition, the empty space between the connection portion  580   a  and the housing  140  may be filled with a damper (not illustrated). 
     The distance between the sixth coupling region S 6  and the reference line (e.g.  502 ) may be smaller than the distance between the fifth coupling region S 5  and the reference line (e.g.  502 ). 
     The first coupling portion  560  and the second coupling portion  570   a  may realize single contact owing to the connection portion  580   a.    
     Each of the fifth and sixth upper elastic members  150 - 5  and  150 - 6  may include the first coupling portion  570 , which has the coupling regions P 1  and P 2  for the coupling of the housing  140 , the second coupling portion  570   b , which is coupled to any one of the support members, the connection portion  580   b , which connects the first coupling portion  570  and the second coupling portion  570   b  to each other, and the third coupling portion  590 , which is connected to the first coupling portion  570  and is coupled to the other one of the support members. 
     The first coupling portion  570  may come into contact with the upper surface of the housing  140  and may be supported by the upper surface of the housing  140 , whereas the connection portion  580   b  may not be supported by the upper surface of the housing  140 , and the second coupling portion  570   b  may not come into contact with the housing  140  and may be spaced apart from the housing  140 . 
     The empty space between the connection portion  580   b  and the housing  140  may be filled with a damper (not illustrated). 
     The first coupling portion  560  of any one upper elastic member  150 - 2  or  150 - 4  among the first to fourth upper elastic members  150 - 1  to  150 - 4  and the first coupling portion  570  of a corresponding one of the fifth and sixth upper elastic members  150 - 5  and  150 - 6  may be spaced apart from each other, and may be left-right symmetrical to each other about the reference line (e.g.  502  or  504 ). 
     The first distance between the reference line  502  or  504  and the coupling region P 1 , which is connected to the connection portion  580   b , among the coupling regions P 1  and P 2  of each of the fifth and sixth upper elastic members  150 - 5  and  150 - 6  may be smaller than the second distance between the reference line  502  or  504  and the remaining coupling region P 2  excluding the coupling region P 1  connected to the connection portion  580   b.    
     In another embodiment, in the case where the electrical connection between the fifth and sixth upper elastic members  150 - 5  and  150 - 6  and the lower elastic member  160  is not necessary, the fifth and sixth upper elastic members  150 - 5  and  150 - 6  may be omitted. In addition, in the case where the fifth and sixth upper elastic members  150 - 5  and  150 - 6  are omitted, the second coupling portion  570   a  of the second upper elastic member  150 - 2  may be aligned with the reference line  504  so as to overlap the reference line  504 , and the second coupling portion  570   a  of the fourth upper elastic member  150 - 4  may be aligned with the reference line  502  so as to overlap the reference line  502 . This serves to limit the tilting and rotation of an Optical Image Stabilization (OIS) movable unit during hand tremor compensation. 
     The first and third upper elastic members  150 - 1  and  150 - 3  may have the same shape, and thus a description related to any one of both the upper elastic members  150 - 1  and  150 - 3  may be equally applied to the other one. 
     In addition, the second and fourth upper elastic members  150 - 2  and  150 - 4  may have the same shape, and thus a description related to any one of both the upper elastic members  150 - 2  and  150 - 4  may be equally applied to the other one. 
     In addition, the fifth and sixth upper elastic members  150 - 5  and  150 - 6  may have the same shape, and thus a description related to any one of both the upper elastic members  150 - 5  and  150 - 6  may be equally applied to the other one. 
     Although each of the upper and lower elastic members  150  and  160  of the embodiment is divided into two or more parts, in another embodiment, each of the upper and lower elastic members  150  and  160  may not be divided. 
     The second coupling boss  117  of the bobbin  110  may be coupled and fixed to a through-hole  161   a  formed in the second inner frame  161 - 1  or  161 - 2  of the lower elastic member  160  by thermal bonding or using an adhesive such as, for example, epoxy. The second lower support boss  145  of the housing  140  may be coupled and fixed to a through-hole  161   b  formed in the second outer frame  162 - 1  or  162 - 2  of the lower elastic member  160  by thermal bonding or using an adhesive such as, for example, epoxy. 
     Each of the upper elastic member  150  and the lower elastic member  160  may take the form of a leaf spring, without being limited thereto, and may take the form of a coil spring, for example. 
     In one example, the connection portions  530   a ,  530   b ,  580   a  and  580   b  of the upper elastic members  150  may be formed by support members, for example, springs (e.g. leaf springs). In another example, each of the connection portions  530   a ,  530   b ,  580   a  and  580   b  of the upper elastic members  150  may include a zigzag-shaped region, or at least one curved region or bent region. 
     In another embodiment, the role of electrical connection between the upper elastic members  150  and the role of electrical connection between the lower elastic members  160  may be exchanged. 
     The support members  220 - 1  to  220 - 6  according to the embodiment are spaced apart from the housing  140 , and are directly connected to the second coupling portions  520   a ,  520   b ,  570   a , and  570   b  and the connection portions  530   a ,  530   b ,  580   a  and  580   b , rather than being fixed to the housing  140 . 
     Because the connection portions  530   a ,  530   b ,  580   a  and  580   b  are not supported by the upper surface of the housing  140  and the second coupling portions  520   a ,  520   b ,  570   a , and  570   b  are spaced apart from the housing  140 , the second coupling portions  520   a ,  520   b ,  570   a , and  570   b  and the connection portions  530   a ,  530   b ,  580   a  and  580   b  may easily move in the first direction. The support members  220 - 1  to  220 - 6  according to the embodiment are directly connected to the second coupling portions  520   a ,  520   b ,  570   a , and  570   b  and the connection portions  530   a ,  530   b ,  580   a  and  580   b , which are easily movable in the first direction, and therefore are more easily movable in the first direction than general support members, which are fixed to the housing  140 . In this way, the support members  220 - 1  to  220 - 6  may improve the accuracy of hand tremor compensation. In particular, the support members  220 - 1  to  220 - 6  may distribute stress due to falling and shock, which may restrict the deformation of the support members  220 - 1  to  220 - 6  and inhibit electrical disconnection. 
     In addition, because the width W 2  of the connection portions  530   a ,  530   b ,  580   a  and  580   b  is smaller than the width W 1  of the frame connection portion  143 , ease in the movement of the support members  220 - 1  to  220 - 6  in the first direction may be enhanced. 
     In addition, when the width of the second frame connection portions  163 - 1  and  163 - 2  of the lower elastic members  160  is greater than the width of the connection portions  530   a ,  530   b ,  580   a  and  580   b  of the upper elastic members  150 , the connection portions  530   a ,  530   b ,  580   a  and  580   b  may easily move in the optical axis, or in the first direction, which is parallel to the optical axis, thereby distributing stress applied to the upper elastic members  150  and/or stress applied to the support members  220 . 
     In addition, because the connection portions  530   a ,  530   b ,  580   a  and  580   b  are bent at least one time, the overall length of the connection portions  530   a ,  530   b ,  580   a  and  580   b  may be increased. In this way, the embodiment may distribute stress applied to the upper elastic members  150  and/or the support members  220 , and may inhibit the connection portions  530   a ,  530   b ,  580   a  and  580   b  from being broken by stress, which is applied to the upper elastic members  150  and/or the support members  220  due to shock. 
     In addition, because the connection portions  530   a ,  530   b ,  580   a  and  580   b  realize single contact between the second coupling portion  520   a ,  520   b ,  570   a , or  570   b  and the first coupling portion  510 ,  560 , or  570 , ease in the movement of the connection portions  530   a ,  530   b ,  580   a  and  580   b  in the first direction may further be enhanced, and the stress, which is applied to the upper elastic members  150  and/or the support members  220  due to shock, may be more efficiently distributed. 
     In addition, because the stress, which is applied to the upper elastic members  150  and/or the support members  220  due to shocks is distributed by the connection portions  530   a ,  530   b ,  580   a  and  580   b , with regard to feedback control for hand tremor compensation, the frequency resonance characteristic of signals output from second position sensors  240   a  and  240   b  may restrict the generation of a high resonant frequency. 
     In another embodiment, a lens moving apparatus may include the bobbin  110  in which a lens is mounted, the housing  140 , which accommodates the bobbin  110  therein, the magnet  130  and the second coil  230 , which electromagnetically interact with each other so as to move the housing  140 , an upper spring  150 , which is mounted to both the bobbin  110  and the housing  140 , a curvilinear shock-absorbing portion having one end connected to a portion of the upper spring  150 , and a support member  220  (e.g. a suspension wire) connected to the other end of the damping member. The shock-absorbing portion may be bent at least one time. In addition, the lens moving apparatus according to the present embodiment may further include at least one of the constituent elements  120 ,  160 ,  170 ,  180 ,  240 ,  250 , and  300  illustrated in  FIG. 2 . 
     Here, the shock-absorbing portion may include the connection portions  530   a ,  530   b ,  580   a  and  580   b  and the second coupling portions  520   a ,  520   b ,  570   a  and  570   b . The descriptions of the connection portions  530   a ,  530   b ,  580   a  and  580   b  and the second coupling portions  520   a ,  520   b ,  570   a  and  570   b  may be applied to the shock-absorbing portion. 
     In addition, the upper spring  150  may include the first inner frame  151 , the first outer frame having the first coupling portions  510 ,  560  and  570 , and the frame connection portion  153 . 
     The shock-absorbing portion may be located near a first connection region (e.g. the solder  901  in  FIG. 14A ) of the upper spring  150  and the support member  220 . In addition, the shock-absorbing portion may be located between a second connection region (e.g. any one of the coupling regions S 1  to S 6  and P 1  and P 2 ) of the upper spring  150  and the housing  140  and the first connection region (e.g. the solder  901  in  FIG. 14A ). 
     For example, two shock-absorbing portions  520   a ,  530   a    520   b , and  530   b  may be formed on at least one corner of the upper spring  150 . The upper spring  150  may be divided into a plurality of upper springs  150 - 1  to  150 - 8  and a plurality of shock-absorbing portions may be provided such that the shock-absorbing portions may be connected to the respective upper springs. A plurality of support members  220  (e.g. a plurality of suspension wires) may be provided such that the respective support members (e.g. the suspension wires) may be electrically connected to a corresponding one of the upper springs via the respective shock-absorbing portions. 
     Next, the base  210 , the circuit board  250 , and the second coil  230  will be described. 
     The base  210  may have a bore corresponding to the bore of the bobbin  110  and/or the bore of the housing  140 , and may have a shape that coincides with or corresponds to that of the cover member  300 , for example, a square shape. 
       FIG. 10  is an exploded perspective view of the base  210 , the second coil  230 , the second position sensor  240 , and the circuit board  250  illustrated in  FIG. 2 . 
     Referring to  FIG. 10 , the base  210  may have a stepped portion  211 , to which an adhesive may be applied when the cover member  300  is fixed to the base  210  using the adhesive. At this time, the stepped portion  211  may guide the cover member  300  coupled to the upper side thereof, and may come into contact with the end of the cover member  300 . 
     The stepped portion  211  of the base  210  and the end of the cover member  300  may be attached or fixed to each other using, for example, an adhesive. 
     The base  210  may be provided with a support portion  255  on one side thereof facing a terminal  251  of the circuit board  250 . The support portion  255  may support a terminal surface  253  of the circuit board  250 , on which the terminal  251  is formed. 
     A second recess  212  may be formed in a region of the base  210  corresponding to each corner of the cover member  300 . When the cover member  300  has a protrusion formed at each corner thereof, the protrusion of the cover member  300  may be fitted into the second recess  212  of the base  210 . 
     In addition, second seating recesses  215 - 1  and  215 - 2  may be formed in the upper surface of the base  210  so that the second position sensor  240  may be disposed in each of the second seating recesses  215 - 1  and  215 - 2 . 
     In the embodiment, two second seating recesses  215 - 1  and  215 - 2  may be provided, and two second position sensors  240   a  and  240   b  may be located respectively in a corresponding one of the two second seating recesses  215 - 1  and  215 - 2 . A seating portion (not illustrated) for a filter  610  (see  FIG. 16 ) may be formed in the lower surface of the base  210 . 
     The support member  220  may be configured as an elastic support member such as, for example, a leaf spring, a coil spring, or a suspension wire. In another embodiment, the support member  220  may be integrally formed with the upper elastic member  150 . 
     Meanwhile, the support members  220 - 1  to  220 - 8  may be disposed on the second side portions  142  of the housing  140 . For example, one or more support members  220 - 1  to  220 - 8  may be disposed on each of the four second side portions  142 . In another embodiment, the support members  220  may be leaf springs disposed on the first side portions  141  of the housing  140 . 
     For example, the second coil  230  may be disposed above the circuit board  250 , and the second position sensor  240  may be disposed below the circuit board  250 . 
     The second position sensor  240  may sense displacement of an OIS movable unit in the direction perpendicular to the optical axis. Although the second position sensor  240  and the magnet  130  may be arranged on the same axis, without being limited thereto. 
     Here, the OIS movable unit may include an AF movable unit and constituent elements mounted to the housing  140 . For example, the OIS movable unit may at least include the AF movable unit and the housing  140 , and in some embodiments, the OIS movable unit may further include the magnets  130 - 1  to  130 - 4 . For example, the AF movable unit may include the bobbin  110  and constituent elements, which are mounted to the bobbin  110  so as to move along with the bobbin  110 . For example, the AF movable unit may at least include the bobbin  110  and a lens (not illustrated) mounted in the bobbin  110 . In some embodiments, the AF movable unit may further include at least one of the first coil  120  and the first position sensor  170 . 
     The circuit board  250  may be disposed on the upper surface of the base  210 , and may have a bore corresponding to the bore of the bobbin  110 , the bore of the housing  140  and/or the bore of the base  210 . The outer circumferential surface of the circuit board  250  may have a shape that coincides with or corresponds to the upper surface of the base  210 , for example, a square shape. 
     The circuit board  250  may include at least one terminal surface  253 , which is bent from the upper surface and is provided with a plurality of terminals or pins, which receive electrical signals from the outside. 
     In  FIG. 10 , the second coil  230  is implemented as being provided on the circuit member  231 , which is separate from the circuit board  250 , without being limited thereto. In another embodiment, the second coil  230  may take the form of a ring-shaped coil block, an FP coil, or a circuit pattern formed on the circuit board  250 . 
     The second coil  230  may have through-holes  230   a  formed in the circuit member  231 , and the support members  220 - 1  to  220 - 4 ,  220 - 5  and  220 - 7  may penetrate the through-holes  230   a  so as to be electrically connected to the circuit board  250 . For example, the support members  220 - 1  to  220 - 4 ,  220 - 5  and  220 - 7  may be electrically connected to the circuit board  250  via thermal bonding such as, for example, soldering. 
     The second coil  230  is located above the circuit board  250  so as to be opposite to the magnet  130  fixed to the housing  140 . 
     Although four second coils  230  may be installed on four sides of the circuit member  231 , the embodiment is not limited thereto, and only two second coils may be installed respectively in the second direction and the third direction, or four or more second coils may be installed. 
     The housing  140  may move in the second direction and/or the third direction, for example, in the X-axis and/or the Y-axis via interaction of the magnet  130  and the second coil  230  arranged to be opposite to each other as described above, thereby performing hand tremor compensation. 
     The second position sensor  240  may be a Hall sensor, and any other sensors may be used so long as they can sense the strength of a magnetic field. For example, the second position sensor  240  may take the form of a driver including a Hall sensor, or may be configured as a position detection sensor alone such as, for example, a Hall sensor. 
     At least one terminal  251  may be installed on the terminal surface  253  of the circuit board  250 . The circuit board  250  may receive external power through a plurality of terminals  251  installed on the terminal surface  253  and may supply the power to the first and second coils  120  and  230  and the first and second position sensors  170  and  240 , and may outwardly output signals received from the first and second position sensors  170  and  240 . 
     In some embodiments, the circuit board  250  may be a Flexible Printed Circuit Board (FPCB), without being limited thereto, and the terminals  251  of the circuit board  250  may be directly formed on the surface of the base  210  via, for example, a surface electrode method.

     For example, the adhesive member  612  may be, for example, epoxy, thermosetting adhesive, or ultraviolet curing adhesive. 
     The filter  610  may serve to inhibit light within a specific frequency band having passed through the lens barrel  400  from being introduced into the image sensor  810 . The filter  610  may be an infrared-light blocking filter, without being limited thereto. At this time, the filter  610  may be oriented parallel to the X-Y plane. 
     A region of the first holder  600  in which the filter  610  is mounted may be provided with a bore in order to allow the light having passed through the filter  610  to be introduced into the image sensor  810 . 
     The second holder  800  may be disposed under the first holder  600 , and the image sensor  810  may be mounted on the second holder  600 . The light having passed through the filter  610  is introduced into the image sensor  810  so as to form an image on the image sensor  810 .

     The hand tremor controller  830  may be mounted on the second holder  800 , and may be electrically connected to the second position sensor  240  and the second coil  230  of the lens moving apparatus  100 . For example, the second holder  800  may be electrically connected to the circuit board  250  of the lens moving apparatus  100 , and the hand tremor controller  820  mounted on the second holder  800  may be electrically connected to the second position sensor  240  and the second coil  230  through the circuit board  250 . 
     The hand tremor controller  830  may output a drive signal, which is required to allow the OIS movable unit of the lens moving apparatus  100  to perform hand tremor compensation, based on signals output from the second position sensor  240  of the lens moving apparatus  100 . 
     The connector  840  may be electrically connected to the second holder  800 , and may have a port for the electrical connection of an external appliance.

     The body  850  may include a case (e.g. casing, housing, or cover) defining the external appearance of the terminal. For example, the body  850  may be divided into a front case  851  and a rear case  852 . A variety of electronic components of the terminal may be mounted in the space defined between the front case  851  and the rear case  852 . 
     The wireless communication unit  710  may include one or more modules, which enable wireless communication between the terminal  200 A and a wireless communication system or between the terminal  200 A and a network in which the terminal  200 A is located.

     The camera  721  may be the camera module  200  according to the embodiment illustrated in  FIG. 16 . 
     The sensing unit  740  may sense the current state of the terminal  200 A such as, for example, the opening or closing of the terminal  200 A, the location of the terminal  200 A, the presence of user touch, the orientation of the terminal  200 A, or the acceleration/deceleration of the terminal  200 A, and may generate a sensing signal to control the operation of the terminal  200 A. For example, when the terminal  200 A is a slide type phone, the sensing unit  740  may sense whether the slide type phone is opened or closed. In addition, the sensing unit  740  serves to sense, for example, whether power is supplied from the power supply unit  790 , or whether the interface unit  770  is coupled to an external appliance. 
     The input/output unit  750  serves to generate, for example, visual, audible, or tactile input or output. The input/output unit  750  may generate input data to control the operation of the terminal  200 A, and may display information processed in the terminal  200 A. 
     The input/output unit  750  may include a keypad unit  730 , a display module  751 , a sound output module  752 , and a touchscreen panel  753 . The keypad unit  730  may generate input data in response to input to a keypad.
