Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the disclosure. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness. 
     The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the disclosure. Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the disclosure is provided for illustration purpose only and not for the purpose of limiting the disclosure as defined by the appended claims and their equivalents. 
     It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces. 
       FIG.  1    illustrates a first state of an electronic device according to an embodiment of the disclosure. 
       FIG.  2    illustrates a second state of an electronic device according to an embodiment of the disclosure. 
     Referring to  FIGS.  1  and  2   , the electronic device  100  according to an embodiment may include a first structure  110 , a second structure  160 , and a display  170 . 
     In an embodiment, the electronic device  100  may be an electronic device of a slidable type or a rollable type and may include the first state  101  (e.g., a closing mode, a reduction mode, or a slide-in mode) and the second state  102  (e.g., an opening mode, an expansion mode, or a slide-out mode). For example, the first state  101  and the second state  102  of the electronic device  100  may be determined depending on the position of the second structure  160  relative to the first structure  110  or the area of the display  170  exposed on a front side of the electronic device  100 . In various embodiments, the electronic device  100  may be changed (or, switched) between the first state  101  and the second state  102  by a user operation or an automatic mechanical operation. 
     In an embodiment, the first state  101  may refer to a state in which the area (or, size) of the display  170  that is exposed on the front side (e.g., the side facing the +Z-axis direction) of the electronic device  100  (or, that forms the front side) is relatively reduced (refer to  FIG.  1   ). The second state may refer to a state in which the area (or, size) of the display  170  that is exposed on the front side of the electronic device  100  (or, that forms the front side) is increased (refer to  FIG.  2   ). For example, the first state  101  may refer to a state in which the area of the display  170  exposed on the front side of the electronic device  100  is minimal. The second state  102  may refer to a state in which the area of the display  170  exposed on the front side of the electronic device  100  is maximal. 
     In various embodiments, the electronic device  100  may include an intermediate state (e.g., a third state) between the first state  101  and the second state  102 . In the intermediate state, the area of the display  170  exposed on the front side of the electronic device  100  may be greater than that in the first state  101  and may be smaller than that in the second state  102 . For example, the intermediate state may refer to a state before the electronic device  100  is completely changed from the first state  101  to the second state  102  or from the second state  102  to the first state  101 . For example, the intermediate state may be understood as comprehensively referring to various states between the first state  101  and the second state  102 . 
     In an embodiment, the first structure  110  and the second structure  160  may be coupled so as to be slidable relative to each other. The second structure  160  may be slidably coupled to one side of the first structure  110 . For example, the first structure  110  may be a fixed structure, and the second structure  160  may be a structure movable relative to the first structure  110 . The second structure  160  may be coupled to the one side of the first structure  110  so as to be slidable in opposite directions D 1  and D 2  (e.g., the +X/−X-axis directions) relative to the first structure  110 . 
     According to various embodiments, the first structure  110  may refer to a first housing, a fixed member, a fixed housing, or a fixed case. In various embodiments, the second structure  160  may refer to a second housing, a sliding member (a slider), a sliding housing, or a sliding case. 
     In an embodiment, the second structure  160  may slide relative to the first structure  110  to change the electronic device  100  to the first state and the second state. For example, the electronic device  100  may be changed to the second state  102  (e.g., the state of  FIG.  2   ) as the second structure  160  moves in the first direction D 1  relative to the first structure  110  in the first state  101  (e.g., the state of  FIG.  1   ). In contrast, the electronic device  100  may be transformed to the first state  101  as the second structure  160  moves in the second direction D 2  relative to the first structure  110  in the second state  102 . 
     In another embodiment, when the electronic device  100  is in the first state  101 , part (e.g., a first peripheral portion  161  and a second peripheral portion  162 ) of the second structure  160  may be located inward of side covers  133  and  135  of the first structure  110 . Accordingly, the second structure  160  may be in a closed state with respect to the first structure  110 . When the electronic device  100  is in the second state  102 , part of the first peripheral portion  161  and part of the second peripheral portion  162  may move out of the first structure  110  and may be exposed outside the side covers  133  and  135 . Accordingly, the second structure  160  may be in an opened state with respect to the first structure  110 . 
     In another embodiment, the size (or, area) of a region (e.g., an exposed region) of the display  170  visually exposed on the front side of the electronic device  100  may be changed in response to a sliding motion of the second structure  160 . A partial area of the display  170  may be supported by the second structure  160  so as to move together with the second structure  160 . For example, the display  170  may be configured to move together with the second structure  160  to expand or reduce the exposed region when the second structure  160  slides relative to the first structure  110 . 
     In another embodiment, the display  170  may include a flexible portion (or, a rollable portion). For example, the display  170  may extend in a bent form such that depending on states (e.g., the first state  101  and the second state  102 ) of the electronic device  100 , part of the display  170  faces a direction toward the front side of the electronic device  100  (e.g., the +Z-axis direction) and another part of the display  170  faces a direction toward a rear side of the electronic device  100  (e.g., the −Z-axis direction). 
     In another embodiment, the display  170  may include a first area  171  and a second area  173  extending from the first area  171 . The first area  171  may form the front side of the electronic device  100 . For example, the first area  171  may remain visually exposed on the front side of the electronic device  100  irrespective of states of the electronic device  100 . The second area  173  may form the front side of the electronic device  100  in the second state. For example, the second area  173  may be located inside the first structure  110  such that the second area  173  is or is not visually exposed on the front side of the electronic device  100  depending on states of the electronic device  100 . The area by which the second area  173  is exposed on the front side of the electronic device  100  may vary depending on a sliding distance of the second structure  160 . In various embodiments, the first area  171  may be understood as a default area, a fixed area, or a main area, and the second area  173  may be understood as an expanded area, a variable area, or a sub-area. 
     In another embodiment, the second area  173  may extend from the first area  171  in one direction. For example, the direction in which the second area  173  extends from the first area  171  may be opposite to the direction in which the second structure  160  moves when the electronic device  100  is expanded. For example, the second area  173  may extend from the first area  171  in the second direction D 2 . As the second structure  160  slides relative to the first structure  110 , the second area  173  moves into the first structure  110  (e.g., slide-in motion), or moves out of the first structure  110  (e.g., slide-out motion). 
     In another embodiment, the first area  171  and the second area  173  of the display  170  may be distinguished from each other, depending on whether the first area  171  and the second area  173  are exposed on the front side of the electronic device  100  in the first state  101 . For example, the first area  171  may refer to a partial area of the display  170  visually exposed on the front side of the electronic device  100  in the first state  101 . The second area  173  may refer to a partial area of the display  170  that, in the first state  101 , is located inside the first structure  110  so as not to be exposed on the front side of the electronic device  100  and, in the second state  102 , is at least partially moved out of the first structure  110 , so as to be visually exposed on the front side of the electronic device  100 . For example, the second area  173  may be understood as indicating the remaining area other than the first area  171  in the entire area of the display  170 . Furthermore, the first area  171  and the second area  173  of the display  170  do not mean that the first area  171  and the second area  173  are physically divided from each other or have different shapes or properties. 
     In another embodiment, the first state  101  may be a state in which the first area  171  forms the front side of the electronic device  100  and the second area  173  is located inside the first structure  110 . The second state  102  may be a state in which part of the second area  173 , together with the first area  171 , forms the front side of the electronic device  100 . For example, the second state may refer to a state in which the area by which the second area  173  is exposed on the front side of the electronic device  100  is maximal. 
     In various embodiments, the display  170  may form a screen display area that is visually exposed on the front side of the electronic device  100  and on which predetermined visual information (or, a screen) is displayed. For example, in the first state, the screen display area may be formed by the first area  171 . In the second state, the screen display area may be formed by part of the second area  173  and the first area  171 . In the second state, the electronic device  100  may provide an expanded screen display area, as compared with when the electronic device  100  is in the first state. For example, the screen display area may be substantially the same as the exposed region of the display  170 , or may be smaller than the exposed region. 
     In another embodiment, the electronic device  100  may include a camera decoration member  124  formed on the rear side (e.g., the side facing the −Z-axis direction) of the electronic device  100 . For example, one or more rear camera modules (e.g., a plurality of rear cameras  320  of  FIGS.  8 A and  8 B ) may be disposed inside the first structure  110 , and the plurality of rear cameras  320  may be visually exposed on the rear side of the electronic device  100  through the camera decoration member  124  (e.g., a camera window) (refer to  FIG.  8 A ). In various embodiments, the camera decoration member  124  may be configured to protrude from the rear side of the electronic device  100  by a specified height by the thickness (e.g., the length in the Z-axis direction) of the plurality of rear cameras  320  (e.g., refer to  FIGS.  15  to  17   ). 
       FIG.  3    is an exploded perspective view of the electronic device according to an embodiment of the disclosure. 
     Referring to  FIG.  3   , the electronic device  100  according to an embodiment may include the first structure  110 , the second structure  160 , the display  170 , a drive member  180 , a roller  191 , a battery  192 , a display support member  193 , and a plurality of circuit boards  210 . 
     In an embodiment, the first structure  110  may form at least part of the exterior (or, the outer surface) of the electronic device  100 . For example, the first structure  110  may form the rear side and a part of lateral sides of the electronic device  100 . In another embodiment, the first structure  110  may provide a space in which other components of the electronic device  100  are supported and/or disposed. For example, the battery  192  or the plurality of circuit boards  210  may be disposed inside the first structure  110 . For example, the second structure  160  may be slidably supported on part (e.g., a bracket  140 ) of the first structure  110 . 
     In another embodiment, the first structure  110  may include a rear member  120 , a side member  130 , the bracket  140 , and a guide member  150 . For example, the rear member  120 , the side member  130 , the bracket  140 , and the guide member  150  may be fixed structures that are the basis of a relative movement of the second structure  160 . For example, the second structure  160  may slide in the opposite directions relative to the rear member  120 , the side member  130 , the bracket  140 , and the guide member  150 . 
     In another embodiment, the first structure  110  may be formed through a coupling structure of the rear member  120 , the side member  130 , the bracket  140 , and the guide member  150 . For example, the rear member  120  and the side member  130  may form the rear side and a part of the lateral sides of the electronic device  100  and may form a predetermined space in which other components of the electronic device  100  are disposed. According to the illustrated embodiment, the first structure  110  may be configured such that the rear member  120 , the side member  130 , the bracket  140 , and the guide member  150  are assembled together. However, according to various embodiments, at least some of the rear member  120 , the side member  130 , the bracket  140 , and the guide member  150  may be integrally formed. 
     In another embodiment, the rear member  120  may include a back cover  121  forming the rear side of the electronic device  100  and a rear case  122  disposed on one surface of the back cover  121 . For example, the rear case  122  may be disposed on an upper surface (e.g., a surface facing the +Z-axis direction) of the back cover  121  to support the plurality of circuit boards  210  and/or the battery  192  disposed inside the first structure  110 . For example, the rear case  122  may be located to face the bracket  140  with the plurality of circuit boards  210  and the battery  192  therebetween. 
     In another embodiment, the camera decoration member  124  may be disposed on the back cover  121 . For example, the back cover  121  may have, in a partial area thereof, an opening area  123  into which part of the camera decoration member  124  is inserted. The camera decoration member  124  may be exposed on the rear side of the electronic device  100  through the opening area  123 . In various embodiments, the plurality of rear cameras  320  disposed inside the electronic device  100  may be configured to receive light from outside the electronic device  100  through a transparent and/or translucent area of the camera decoration member  124 . 
     In another embodiment, the side member  130  may be located on opposite longitudinal end portions of the rear member  120  to form a part of the lateral sides of the electronic device  100 . For example, the side member  130  may form a lateral side facing the Y-axis direction among the lateral sides of the electronic device  100 . The side member  130  may include a first side member  131  located on an end portion of the rear member  120  that faces the +Y-axis direction and a second side member  132  located on an end portion of the rear member  120  that faces the −Y-axis direction. 
     In another embodiment, the side member  130  may be coupled to the bracket  140 . For example, the side member  130  may be fixed to the bracket  140  through screw coupling. The first side member  131  may include the first side cover  133  coupled to a first edge portion  143  (e.g., an edge portion facing the +Y-axis direction) of the bracket  140  that is parallel to the sliding directions D 1  and D 2  and a first decoration member  134  coupled to the first side cover  133  to form an outer surface of the electronic device  100 . The second side member  132  may include the second side cover  135  coupled to a second edge portion  144  (e.g., an edge portion facing the −Y-axis direction) that faces away from the first edge portion  143  and a second decoration member  136  coupled to the second side cover  135  to form an outer surface of the electronic device  100 . The first decoration member  134  and the second decoration member  136  may improve the completeness and aesthetics of the electronic device  100  in appearance. For example, the side decoration members  134  and  136  may hide screws and coupling holes when the side covers  133  and  135  are screw-coupled to the bracket  140 . In various embodiments, the side decoration members  134  and  136  may be integrally formed with the side covers  133  and  135 . 
     In another embodiment, the bracket  140  may support other components included in the electronic device  100 .

       FIG.  4    is a sectional view of an electronic device according to an embodiment of the disclosure. 
     Referring to  FIG.  4   , panel  401  is a sectional view illustrating the first state of the electronic device  100 , and panel  402  of  FIG.  4    is a sectional view illustrating the second state of the electronic device  100 . 
     Panel  401  is a sectional view of the electronic device  100  taken along line S 1 -S 1 ′ in  FIG.  1   . Panel  402  of  FIG.  4    is a sectional view of the electronic device  100  taken along line S 2 -S 2 ′ in  FIG.  2   . 
     The electronic device  100  according to an embodiment may include the first structure  110 , the second structure  160 , the display  170 , the drive member  180 , the display support member  193 , the roller  191  and the battery  192 . 
     The components of the electronic device  100  illustrated in  FIG.  4    are identical or similar to some of the components of the electronic device  100  illustrated in  FIGS.  1  to  3   , and repetitive descriptions will be omitted. 
     In an embodiment, the electronic device  100  may be changed to the first state (e.g.,  FIG.  1  or  401    of  FIG.  4   ) and the second state (e.g.,  FIG.  2    or panel  402  of  FIG.  4   ) by a sliding motion of the second structure  160  relative to the first structure  110 . For example, the first structure  110  may be a relatively fixed structure with respect to the sliding of the second structure  160 . 
     In another embodiment, the first structure  110  may include the back cover  121 , the rear case  122 , and the bracket  140 . Although not illustrated in  FIG.  4   , the first structure  110  may further include a side member (e.g., the side member  130  of  FIG.  3   ) and a guide member (e.g., the guide member  150  of  FIG.  3   ). For example, the second structure  160  is disposed over the first surface  141  of the bracket  140  and may move in the first direction D 1  or the second direction D 2  relative to the back cover  121 , the rear case  122 , and the bracket  140 . 
     In another embodiment, the bracket  140  may be disposed between the second structure  160  and the back cover  121 . For example, the bracket  140  is disposed such that the first surface  141  faces toward the second structure  160  and the second surface  142  faces toward the back cover  121  or the rear case  122 . The battery  192  may be disposed on the second surface  142  of the bracket  140 . The battery  192  may be supported by the rear case  122  and the bracket  140 . In an embodiment, the roller  191  may be coupled to one side of the bracket  140  so as to be rotatable about an axis of rotation R. 
     In another embodiment, the second structure  160  may be configured to move in the first direction D 1  or the second direction D 2  relative to the bracket  140 . For example, when the first area  171  of the display  170  is viewed from above, the second structure  160  is partially overlap the bracket  140 . The size of the area by which the second structure  160  and the bracket  140  overlap each other may be changed in response to sliding of the second structure  160 . For example, the area by which the second structure  160  and the bracket  140  overlap each other is relatively smaller in the second state than in the first state. The fourth surface  164   b  of the second structure  160  may be exposed outside the electronic device  100  as the electronic device  100  is changed from the first state to the second state. For example, the fourth surface  164   b  of the second structure  160 , together with the back cover  121 , forms the rear side of the electronic device  100  in the second state or in the intermediate state between the first state and the second state. 
     In another embodiment, the display  170  may be disposed on the third surface  164   a  of the second structure  160 . For example, part of the first area  171  of the display  170  is attached to the third surface  164   a  of the second structure  160 , and thus the display  170  may move together when the second structure  160  moves. As the second structure  160  moves in the second direction D 2 , the second structure  160  may form substantially the same plane with part of the display support member  193 . 
     In another embodiment, the second structure  160  may be connected with the bracket  140  through the drive member  180 . For example, a second support portion  183  of the drive member  180  is coupled to the fourth surface  164   b  of the second structure  160 , and a first support portion  181  of the drive member  180  may be coupled to the first surface  141  of the bracket  140 . In various embodiments, the second structure  160  may be configured to move in the first direction D 1  or the second direction D 2  relative to the bracket  140  by using an elastic force provided by the drive member  180 . 
     In another embodiment, the display  170  may include the first area  171  exposed on the front side (e.g., the side facing the +Z-axis direction) of the electronic device  100  in the first state and the second area  173  extending from the first area  171 . In the second state, at least part of the second area  173 , together with the first area  171 , may be exposed on the front side of the electronic device  100 . For example, in the first state, the second area  173  is located inside the first structure  110 , and in the second state, at least part of the second area  173  may move out of the first structure  110  and may be exposed on the front side of the electronic device  100 . 
     In another embodiment, the first area  171  and the second area  173  of the display  170  may be distinguished from each other, depending on whether the first area  171  and the second area  173  are exposed on the front side of the electronic device  100  in the first state. The position of a dividing line between the first area  171  and the second area  173  is not limited to the specific position illustrated in  FIG.  4   . For example, when the back cover  121  surrounding the display  170  is formed in a higher or lower position than that in the illustrated embodiment, the position of the dividing line between the first area  171  and the second area  173  is changed accordingly. 
     In another embodiment, the display  170  may be configured such that at least part of the first area  171  is fixed to the second structure  160  and part of the second area  173  moves (or, slides) into or out of the first structure  110  as the second structure  160  moves in the opposite directions relative to the first structure  110 . For example, part of the first area  171  is supported by the third surface  164   a  of the second structure  160 , and the remaining part of the first area  171  is supported by the display support member  193 . The second area  173  may be supported by the display support member  193 . 
     In another embodiment, a portion of the display  170  disposed on the third surface  164   a  of the second structure  160  may be a portion that remains substantially flat irrespective of sliding of the second structure  160 . Furthermore, a portion of the display  170  supported by the display support member  193  may be a portion that deforms to be curved or flat in response to sliding of the second structure  160 . For example, the portion of the display  170  supported by the second structure  160  is a rigid portion, and the portion of the display  170  supported by the display support member  193  is a flexible portion. 
     According to the illustrated embodiment, the first area  171  may include the rigid portion and part of the flexible portion, and the second area  173  may include the remaining part of the flexible portion. However, without being limited thereto, according to various embodiments of the disclosure, the entire display  170  may be formed of a flexible material. Furthermore, according to various embodiments, the display  170  may be formed such that rigid portions are located on opposite sides of a flexible portion. 
     In another embodiment, the drive member  180  may be disposed between the second structure  160  and the bracket  140 . For example, the drive member  180  is disposed between the first surface  141  of the bracket  140  and the fourth surface  164   b  of the second structure  160 . The drive member  180  may be located to face the battery  192  with the bracket  140  therebetween. In another embodiment, the drive member  180  may generate elastic forces acting in directions parallel to the sliding directions D 1  and D 2  of the second structure  160 . 
     In another embodiment, the drive member  180  may include the first support portion  181 , the second support portion  183 , and an elastic portion  185 . For example, the elastic portion  185  connects the first support portion  181  and the second support portion  183 . The elastic portion  185  may be compressed or uncompressed depending on a relative movement of the first support portion  181  and the second support portion  183 . 
     In another embodiment, the first support portion  181  may be coupled to the bracket  140 , and the second support portion  183  may be coupled to the second structure  160 . Accordingly, the drive member  180  may connect the second structure  160  and the bracket  140 . For example, the first support portion  181  may be rotatably coupled to the first surface  141  of the bracket  140 . The second support portion  183  may be rotatably coupled to the fourth surface  164   b  of the second structure  160 . The connecting shafts (e.g., the first connecting shaft  145  and the second connecting shaft  165 ) to which the first support portion  181  and the second support portion  183  are rotatably coupled may be formed on the first surface  141  of the bracket  140  and the fourth surface  164   b  of the second structure  160 . 
     In another embodiment, the first support portion  181  may be coupled to the first connecting shaft  145  of the bracket  140 . The second support portion  183  may be coupled to the second connecting shaft  165  of the second structure  160 . For example, the first connecting shaft  145  protrudes from the first surface  141  of the bracket  140  toward the second structure  160 . The second connecting shaft  165  may protrude from the fourth surface  164   b  of the second structure  160  toward the bracket  140 . For example, the first support portion  181  may be rotatably coupled to the first connecting shaft  145 , and the second support portion  183  may be rotatably coupled to the first connecting shaft  145 . 
     In another embodiment, the drive member  180  may be configured such that a relative movement between the first support portion  181  and the second support portion  183  is generated as the second support portion  183  moves together with the second structure  160  when the second structure  160  slides relative to the bracket  140 . For example, the elastic portion  185  is configured to be compressed or uncompressed depending on a movement of the second structure  160  relative to the bracket  140  to apply an elastic force to the second structure  160  with respect to the bracket  140 . For example, when the second structure  160  moves in the first direction D 1  or the second direction D 2 , the drive member  180  may provide an elastic force in the opposite direction to the moving direction of the second structure  160  in a predetermined section (e.g., between a first point A 1  and a second point A 2  in  FIG.  7   ) and may provide an elastic force in the same direction as the moving direction of the second structure  160  after the predetermined section (e.g., between the second point A 2  and a third point A 3  in  FIG.  7   ). The motion of the drive member  180  will be described below in more detail with reference to  FIGS.  5  to  7   . 
     In another embodiment, the display support member  193  may support part of the first area  171  and the second area  173 . For example, the display support member  193  is attached to portions of the rear surface of the display  170  that correspond to the part of the first area  171  and the second area  173 . The display support member  193  may move together with the display  170  when the display  170  moves by a movement of the second structure  160 . 
     In another embodiment, the display support member  193  may include a plurality of bars  1931  (or, protrusions) extending in a direction substantially perpendicular to the sliding directions D 1  and D 2  of the second structure  160 . For example, the display support member  193  may be formed in a form (e.g., a multi-joint module or a multi-bar) in which the plurality of bars  1931  extending in a direction substantially parallel to the roller  191  (or, the axis of rotation R) are disposed at predetermined intervals. For example, the display support member  193  may include a flexible track or a hinge rail. The display support member  193  may be bent at portions having a relatively small thickness between the plurality of bars  1931 . 
     In another embodiment, the display support member  193  may surround at least part of the roller  191 . For example, the display support member  193  may partially make contact with an outer circumferential surface of the roller  191 . The display support member  193  may be formed in a shape at least partially bent while surrounding the roller  191 . For example, the display support member  193  rotates and/or rectilinearly moves along the outer circumferential surface of the roller  191  by rotation of the roller  191  when the second structure  160  slides. 
     In another embodiment, part of the display support member  193  may be disposed between the roller  191  and the back cover  121  and may move along the outer circumferential surface of the roller  191  as the second structure  160  slides. For example, when the second structure  160  moves in the first direction D 1  in the first state, the part of the display support member  193  (or, the second area  173 ) moves out of the space between the back cover  121  and the roller  191  (e.g., slide-out motion) as the roller  191  rotates in a first rotational direction (e.g., the counterclockwise direction). In contrast, when the second structure  160  moves in the second direction D 2  in the second state, the part of the display support member  193  (or, the second area  173 ) may move into the space between the back cover  121  and the roller  191  (e.g., slide-in motion) as the roller  191  rotates in a second rotational direction (e.g., the clockwise direction) opposite to the first rotational direction. 
     In another embodiment, the roller  191  may be disposed on a side surface of the bracket  140  in the second direction D 2  so as to be rotatable. For example, the roller  191  may move the display  170  by rotating about the axis of rotation R substantially perpendicular to the sliding directions D 1  and D 2  of the second structure  160 . The roller  191  may be surrounded by the display support member  193 . For example, the display support member  193  may make contact with part of the outer circumferential surface of the roller  191 . According to the illustrated embodiment, the roller  191  may be configured to rotate about the axis of rotation R, but is not necessarily limited thereto. In various embodiments, the roller  191  may be fixed without rotating relative to the bracket  140 , and the display support member  193  may be configured to move along the outer circumferential surface of the roller  191  that is formed to be a curved surface. 
       FIG.  5    illustrates deformation of an electronic device according to an embodiment of the disclosure. 
       FIG.  6    illustrates a motion of the drive member of an electronic device according to an embodiment of the disclosure. 
       FIG.  7    illustrates a motion of a drive member of an electronic device according to an embodiment of the disclosure. 
     Referring to  FIG.  5   , the state of the electronic device  100  according to an embodiment may be changed as an external force is applied to the display  170 . 
       FIG.  5    may be a schematic view for explaining a motion in which a user slides the display  170  to change the state of the electronic device  100  and may be a view in which other components of the electronic device  100  are omitted. 
     In an embodiment, when the electronic device  100  is in the first state (e.g., refer to panel  401  of  FIG.  4   ), the display  170  may be disposed such that the first area  171  faces toward the front side of the electronic device  100 . The user may slide the display  170  in the first direction D 1  by applying an external force F to the first area  171  of the display  170  in the first direction D 1  in a state of gripping the electronic device  100 . For example, the user may move the second area  173  toward the front side by sliding F the first area  171  of the display  170  in the first direction D 1 . Accordingly, the electronic device  100  may be changed to the second state (e.g., refer to panel  402  of  FIG.  4   ) in which part of the second area  173  is exposed on the front side. 
     In another embodiment, when the electronic device  100  is in the second state, the user may change the electronic device  100  to the first state by sliding the display  170  in the second direction D 2 . 
     Although not illustrated in  FIG.  5   , when the user slides the display  170  in the first direction D 1  or the second direction D 2 , an external force may be transmitted to the second structure  160  on which the first area  171  of the display  170  is disposed, and thus the second structure  160  may move together with the display  170 . For example, the second structure  160  is moved in the first direction D 1  or the second direction D 2  relative to the first structure  110  by the external force applied by the user. 
     The electronic device  100  according to another embodiment may be configured (e.g., a semi-automatic open structure) such that when the electronic device  100  is changed to the first state or the second state, the second structure  160  is moved by an elastic force generated by the drive member  180  even though the external force of the user is removed after the second structure  160  is moved by the external force F of the user by a specified distance or more. 
     Referring to  FIGS.  6  and  7   , the electronic device  100  according to an embodiment may include the first structure  110 , the second structure  160 , and the drive member  180 . In another embodiment, the first structure  110  may include the first side member  131 , the second side member  132 , and the bracket  140 . 
       FIG.  6    may be a plan view of the electronic device  100  when the third surface  164   a  of the second structure  160  is viewed from above and may be a view in which the display  170  is omitted.  FIG.  6    illustrates a motion of the drive member  180 , which is disposed between the second structure  160  (e.g., the fourth surface  164   b  of the second structure  160  of  FIG.  4   ) and the bracket  140  (e.g., the first surface  141  of the bracket  140  of  FIG.  4   ), when the second structure  160  moves relative to the bracket  140 . For example, when the third surface  164   a  of the second structure  160  is viewed from above, the drive member  180  may be hidden by the second structure  160  and may not be visually exposed, but may be understood as being illustrated by a solid line in  FIG.  6    for explanation of the motion of the drive member  180 . 
     Panel  601  of  FIG.  6    illustrates the first state (e.g., the first state  101  of  FIG.  1    and state of an electronic device in panel  401  of  FIG.  4   ) of the electronic device  100 , and panel  602  of  FIG.  6    illustrates the second state (e.g., the second state  102  of  FIG.  2    and a state of the electronic device in panel  402  of  FIG.  4   ) of the electronic device  100 . 
     In another embodiment, the bracket  140  and the second structure  160  may include the connecting shafts  145  and  165 , respectively, to which the drive member  180  is rotatably coupled. For example, the bracket  140  includes the first connecting shaft  145  to which the first support portion  181  of the drive member  180  is coupled. The second structure  160  may include the second connecting shaft  165  to which the second support portion  183  of the drive member  180  is coupled. The first support portion  181  may be rotatably coupled to the first connecting shaft  145 . The second support portion  183  may be rotatably connected to the second connecting shaft  165 . 
     In another embodiment, the first connecting shaft  145  may be fixed to the bracket  140 , and the second connecting shaft  165  may be fixed to the second structure  160 . For example, when the second structure  160  slides relative to the bracket  140 , the second connecting shaft  165  linearly moves in the sliding directions D 1  and D 2  with respect to the relatively fixed first connecting shaft  145 . 
     In another embodiment, the drive member  180  may include the first support portion  181  coupled to the bracket  140 , the second support portion  183  coupled to the second structure  160 , and the elastic portion  185  connecting the first support portion  181  and the second support portion  183 . 
     In another embodiment, the first support portion  181  may be rotatably coupled to the first connecting shaft  145  of the bracket  140 . The second support portion  183  may be rotatably coupled to the second connecting shaft  165  of the second structure  160 . The first support portion  181  coupled to the first connecting shaft  145  may move together with the first connecting shaft  145 , and the second support portion  183  coupled to the second connecting shaft  165  may move together with the second connecting shaft  165 . 
     In another embodiment, the drive member  180  may be configured such that, when the second structure  160  slides relative to the bracket  140 , the first support portion  181  rotates about the first connecting shaft  145  and the second support portion  183  linearly moves together with the second connecting shaft  165  in directions parallel to the sliding directions D 1  and D 2  while rotating about the second connecting shaft  165 . 
     In another embodiment, the second support portion  183  may linearly move together with the second connecting shaft  165  in the sliding directions D 1  and D 2  when the second structure  160  moves relative to the bracket  140 . The first support portion  181  may rotate about the first connecting shaft  145  when the second support portion  183  moves. For example, when the second structure  160  moves, the first support portion  181  rotates about the first connecting shaft  145  in a predetermined range in a state in which a movement in the sliding directions D 1  and D 2  is limited. 
     In another embodiment, in the first state, the second support portion  183  may be located in the second direction D 2  with respect to the first support portion  181 . In the second state, the second support portion  183  may be located in the first direction D 1  with respect to the first support portion  181 . For example, the shape of the drive member  180  illustrated in panel  601  of  FIG.  6    is referred to as the shape of the drive member  180  illustrated in panel  401  of  FIG.  4   , and the shape of the drive member  180  illustrated in panel  602  of  FIG.  6    may be referred to as the shape of the drive member  180  illustrated in panel  402  of  FIG.  4   . For example, when the electronic device  100  is changed to the first state or the second state, the second support portion  183  linearly moves in the first direction D 1  or the second direction D 2  with respect to the first support portion  181 , and the elastic portion  185  may be compressed or uncompressed accordingly. 
     For example, when the electronic device  100  is changed from the first state  101  to the second state  102 , the second connecting shaft  165  and the second support portion  183  move {circle around ( 1 )} in the first direction D 1  as the second structure  160  moves in the first direction D 1 . When the second connecting shaft  165  moves {circle around ( 1 )} in the first direction D 1 , the first support portion  181  may rotate about the first connecting shaft  145 , and the second support portion  183  may move {circle around ( 1 )} together with the second connecting shaft  165  in the first direction D 1  while rotating about the second connecting shaft  165 . 
     For example, when the electronic device  100  is changed from the second state  102  to the first state  101 , the second connecting shaft  165  and the second support portion  183  move {circle around ( 1 )} in the second direction D 2  as the second structure  160  moves in the second direction D 2 . When the second connecting shaft  165  moves {circle around ( 2 )} in the second direction D 2 , the first support portion  181  may rotate about the first connecting shaft  145 , and the second support portion  183  may move {circle around ( 2 )} together with the second connecting shaft  165  in the second direction D 2  while rotating about the second connecting shaft  165 . 
     In another embodiment, as the second support portion  183  moves, the elastic portion  185  may be compressed or uncompressed to generate an elastic force. For example, the elastic portion  185  is compressed or uncompressed as the second support portion  183  linearly moves in the sliding directions D 1  and D 2  relative to the first support portion  181  in the state in which the position of the first support portion  181  in the sliding directions D 1  and D 2  (e.g., the position in the X-axis direction) is fixed. For example, the elastic portion  185  is compressed with a decrease in the distance between the first support portion  181  and the second support portion  183  and may be uncompressed with an increase in the distance between the first support portion  181  and the second support portion  183 . 
     In another embodiment, the elastic portion  185  may be configured to be sequentially compressed and uncompressed when the state of the electronic device  100  is changed. For example, when the state of the electronic device  100  is changed, the elastic portion  185  is compressed while the second structure  160  (or, the second support portion  183 ) moves in the sliding directions D 1  and D 2  by a specified distance and may be uncompressed while the second structure  160  (or, the second support portion  183 ) moves more than the specified distance. For example, the elastic portion  185  provides an elastic force in the opposite direction to the moving direction of the second structure  160  while being compressed and may provide an elastic force in the same direction as the moving direction of the second structure  160  while being uncompressed. 
     In another embodiment, the elastic portion  185  may include various types of springs. According to the illustrated embodiment, the elastic portion  185  may be implemented with a torsion spring. However, without being limited to the illustrated embodiment, the elastic portion  185  may be implemented with a coil spring in various embodiments. 
     In another embodiment, the drive member  180  may include a plurality of drive members. For example, the drive member  180  includes the first drive member  180 - 1  and the second drive member  180 - 2  spaced apart from each other in the direction (e.g., the Y-axis direction) perpendicular to the sliding directions D 1  and D 2 . The first drive member  180 - 1  and the second drive member  180 - 2  may be provided in substantially the same shape and/or structure. However, the number of drive members  180  is not limited to the illustrated embodiment. In various embodiments, the drive member  180  may include one drive member, or may include three or more drive members. In various embodiments, the direction in which the first drive member  180 - 1  and the second drive member  180 - 2  are arranged may be changed. 
     Hereinafter, a motion of the drive member  180  when the state of the electronic device  100  is changed will be described with reference to  FIG.  7   . 
     Referring to  FIG.  7   , the position of the second support portion  183  or the second connecting shaft  165  in the first state (panel  601  of  FIG.  6   ) may be defined as the first point A 1 . The position of the second support portion  183  or the second connecting shaft  165  in the second state (see the electronic device of panel  602  of  FIG.  6   ) may be defined as the third point A 3 . The position of the second support portion  183  or the second connecting shaft  165  when the elastic portion is compressed to the maximum between the first state and the second state (or, when the distance between the second support portion  183  and the first support portion  181  is minimal) may be defined as the second point A 2 . 
     According to another embodiment, with the electronic device  100  in the first state, the second support portion  183  may move in the first direction D 1  when the user slides the second structure  160  in the first direction D 1 . The elastic portion  185  may generate an elastic force in the first direction D 1  when the second support portion  183  moves in the first direction D 1  by a specified distance or more. Even though the user&#39;s external force is removed, the second structure  160  may be moved in the first direction D 1  by the elastic force, and the electronic device  100  may be changed to the second state. 
     For example, when the electronic device  100  is in the first state, the second support portion  183  and the second connecting shaft  165  are located at the first point A 1 . When the second structure  160  and the second connecting shaft  165  move in the first direction D 1  in the first state, the first support portion  181  may rotate about the first connecting shaft  145  in the first rotational direction, and the second support portion  183  may move in the first direction D 1  while rotating about the second connecting shaft  165  in the first rotational direction. Referring to  FIG.  7   , the first rotational direction in a motion of the first drive member  180 - 1  may be the clockwise direction, and the first rotational direction in a motion of the second drive member  180 - 2  may be the counterclockwise direction. 
     For example, the elastic portion  185  is compressed while the second support portion  183  moves from the first point A 1  to the second point A 2  and may be compressed to the maximum at the second point A 2 . The elastic portion  185  may be uncompressed as the second support portion  183  passes through the second point A 2 . For example, while the second support portion  183  moves from the first point A 1  to the second point A 2 , the elastic portion  185  may be compressed to generate an elastic force in the second direction D 2 . While the second support portion  183  moves from the second point A 2  to the third point A 3 , the elastic portion  185  may be uncompressed to generate an elastic force in the first direction D 1 . 
     For example, in a motion in which the electronic device  100  is changed to the second state, the elastic force of the elastic portion  185  acts as a resistive force against sliding of the second structure  160  in the first direction D 1  by the user until the second support portion  183  is located at the second point A 2 . The second support portion  183  may be moved to the third point A 3  by the elastic force after passing through the second point A 2 , and thus the second structure  160  may automatically move in the first direction D 1  even though the user no longer slides the second structure  160 . 
     According to another embodiment, when the user moves the second structure  160  in the second direction D 2  by a specified distance or more, with the electronic device  100  in the second state, the second structure  160  may be moved in the second direction D 2  by the elastic force of the elastic portion  185  even though the user&#39;s external force is removed, and the electronic device  100  may be changed to the first state. For example, when the electronic device  100  is changed from the second state to the first state, the drive member  180  may conversely operate, as compared with when the electronic device  100  is changed from the first state to the second state. 
       FIG.  8 A  is a rear perspective view of an electronic device according to an embodiment of the disclosure. 
       FIG.  8 B  is a rear perspective view of an electronic device according to an embodiment of the disclosure. 
       FIG.  9    illustrates the battery, a plurality of rear cameras, and a plurality of circuit boards of an electronic device according to an embodiment of the disclosure. 
       FIGS.  8 A,  8 B, and  9    may be views illustrating the first state (e.g., the first state  101  of  FIG.  1    or the state illustrated in panel  401  of  FIG.  4   ) of the electronic device  100 . 
       FIG.  8 B  may be a view in which the back cover  121  is omitted from the electronic device  100  illustrated in  FIG.  8 A .  FIG.  9    may be a view in which the display  170  is omitted from the electronic device  100  illustrated in  FIG.  8 B . 
     Referring to  FIGS.  8 A,  8 B, and  9   , the electronic device  100  according to an embodiment may include the back cover  121 , the side members (e.g., the first side member  131  and the second side member  132 ), the bracket  140 , the display  170 , the battery  192 , the plurality of circuit boards  210 , and the plurality of rear cameras  320 . 
     The components of the electronic device  100  illustrated in  FIGS.  8 A,  8 B , and  9  are identical or similar to some of the components of the electronic device  100  illustrated in  FIGS.  1  to  4   , and repetitive descriptions will be omitted. 
     In an embodiment, the plurality of rear cameras  320  may be visually exposed on at least a partial area of the back cover  121 . For example, the camera decoration member  124  is disposed on the back cover  121 , and the plurality of rear cameras  320  may be configured to be visually exposed on the rear side of the electronic device  100  through the camera decoration member  124 . 
     In another embodiment, the bracket  140  may be configured such that the side members  131  and  132  are coupled to opposite longitudinal end portions of the bracket  140 . The bracket  140  may include the second surface  142  (e.g., the second surface  142  of the bracket  140  of  FIG.  4   ) that faces toward the rear side of the electronic device  100  (e.g., the −Z-axis direction). The battery  192 , the plurality of rear cameras  320 , and/or the plurality of circuit boards  210  may be disposed on the second surface  142  of the bracket  140 . For example, the battery  192 , the plurality of rear cameras  320 , and the plurality of circuit boards  210  are fixedly disposed on the second surface  142  of the bracket  140 . 
     In another embodiment, the display  170  may be configured such that at least a partial area (e.g., the second area  173 ) faces toward the rear side of the electronic device  100  in the first state. For example, part of the display  170  illustrated in  FIG.  8 B  is part of the second area  173  (e.g., the second area  173  of  FIG.  4   ) of the display  170  (e.g., refer to panel  401  of  FIG.  4   ). For example, when the electronic device  100  illustrated in  FIG.  8 B  is changed to the second state, part of the second area  173  facing toward the rear side of the electronic device  100  may be moved in the second direction D 2  and may be exposed on the front side of the electronic device  100  (e.g., refer to panel  402  of  FIG.  4   ). 
     In another embodiment, the display  170  may be configured so as not to overlap the plurality of rear cameras  320  in the first state. As illustrated in  FIG.  8 B , when the rear side (e.g., the side facing the −Z-axis direction) of the electronic device  100  is viewed, the second area  173  of the display  170  and the plurality of rear cameras  320  may be spaced apart from each other by a specified gap G in the sliding directions D 1  and D 2  so as not to overlap each other. For example, the size of the area of the display  170  that faces toward the rear side of the electronic device  100  may be maximal in the first state. When the display  170  overlaps the plurality of rear cameras  320  in the first state, the plurality of rear cameras  320  may be hidden by the display  170  and may fail to receive external light. The electronic device  100  according to an embodiment may be configured such that the second area  173  of the display  170  does not hide the plurality of rear cameras  320  in the first state. Accordingly, the plurality of rear cameras  320  may be configured to receive external light through the back cover  121  (e.g., the camera decoration member  124 ) in the first state. 
     In another embodiment, the battery  192  may be disposed on the second surface  142  of the bracket  140 . For example, the battery  192  may be located between the first circuit board  220  and the second circuit board  230  among the plurality of circuit boards  210  when the rear side of the electronic device  100  is viewed. In an embodiment, at least part of the battery  192  may overlap a connecting circuit board  250  connecting the first circuit board  220  and the second circuit board  230 . 
     In another embodiment, the battery  192  may be formed in a shape in which the width of one portion differs from the width of another portion. For example, the battery  192  may include a first portion  192   a  having a first width W 1  and a second portion  192   b  having a second width W 2  smaller than the first width W 1 . The second portion  192   b  may extend from part of the first portion  192   a  in the direction (e.g., the +Y-axis direction) perpendicular to the sliding directions D 1  and D 2 . For example, the battery  192  may be formed in a substantially L-shape. 
     In another embodiment, a step portion (not illustrated) may be formed on the periphery of the battery  192  by the first portion  192   a  and the second portion  192   b . For example, the step portion of the battery  192  provides a space in which at least a part of the plurality of rear cameras  320  is disposed. For example, the second portion  192   b  of the battery  192  may extend toward the first circuit board  220  so as not to interfere with the plurality of rear cameras  320 . 
     In another embodiment, as the second portion  192   b  extends with the second width W 2  from the first portion  192   a , the battery  192  may have different heights along the sliding directions D 1  and D 2 . The thickness of the battery  192  may be substantially uniform. For example, the width of the battery  192  is the length in the X-axis direction (or, the sliding directions D 1  and D 2 ), the heights may be the lengths in the Y-axis direction, and the thickness may be the length in the Z-axis direction. In another embodiment, the battery  192  may be formed such that the height of one part is greater than the height of another portion due to the second portion  192   b , and thus the volume or capacity of the battery  192  may be increased.

For example, the plurality of circuit boards  210  include a plurality of circuit boards (e.g., the first circuit board  220 , the second circuit board  230 , the third circuit board  240 , and the connecting circuit board  250 ) to which the various electronic components are electrically connected.

For example, the first circuit board  220  is disposed on the second surface  142  of the bracket  140  so as to be located adjacent to the first side member  131  (e.g., an upper end of the electronic device  100 ). For example, the second circuit board  230  is disposed on the second surface  142  of the bracket  140  so as to be located adjacent to the second side member  132  (e.g., a lower end of the electronic device  100 ).

     In another embodiment, the connecting circuit board  250  may electrically connect the first circuit board  220  and the second circuit board  230 . For example, the connecting circuit board  250  may extend across part of the battery  192  in the direction perpendicular to the sliding directions D 1  and D 2 . For example, one end portion (e.g., an end portion facing the −Y-axis direction) of the connecting circuit board  250  may be connected with the third connector C 3  of the second circuit board  230 .

The second circuit board layer  223  may be disposed on one surface (e.g., a surface facing the +Z-axis direction) of the first circuit board layer  221  and may be electrically connected with the first circuit board layer  221  through an interposer. In various embodiments, the first circuit board layer  221  may be understood as a master PCB, and the second circuit board layer  223  may be understood as a slave PCB. The stack structure of the first circuit board  220  will be described below in more detail with reference to  FIG.  18   . 
     In another embodiment, the front camera module  310 , the second sensor module  340 , and the first speaker module  330  may be disposed in the module accommodation part  166  of the second structure  160 . The module accommodation part  166  may overlap some of the plurality of rear cameras  320  in the first state and the second state. When the electronic device  100  is changed to the first state or the second state, the module accommodation part  166  may move in the first direction D 1  or the second direction D 2  in the state in which at least part of the module accommodation part  166  overlaps the first camera module  321  in the Z-axis direction. For example, a state in which some of the front camera module  310 , the second sensor module  340 , and the first speaker module  330  overlap the first camera module  321  is formed as the second structure  160  moves. 
     In various embodiments, the second sensor module  340  may include a proximity sensor or an illuminance sensor. However, without being limited to the aforementioned examples, the second sensor module  340  may include at least one of an HRM sensor, a fingerprint sensor, a time of flight (TOF) sensor, an ultrasonic sensor, a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a color sensor, an infrared (IR) sensor, a biosensor, a temperature sensor, or a humidity sensor. 
     According to the illustrated embodiment, the front camera module  310 , the second sensor module  340 , and the first speaker module  330  may be sequentially arranged in the first direction D 1 . However, the positions and/or the arrangement sequence of the front camera module  310 , the second sensor module  340 , and the first speaker module  330  may be variously modified without being limited to the illustrated embodiment. In another embodiment, at least one of the front camera module  310 , the second sensor module  340 , or the first speaker module  330  may be omitted. 
     In another embodiment, in the first state, the first speaker module  330  may overlap the first camera module  321  among the plurality of rear cameras  320  in the Z-axis direction. For example, the first camera module  321  is located under the first speaker module  330  (e.g., the −Z-axis direction). In another embodiment, in a state between the first state and the second state, the front camera module  310  may overlap the first camera module  321  in the Z-axis direction. For example, the first camera module  321  is located under the front camera module  310  (e.g., the −Z-axis direction). According to the embodiment illustrated in  FIG.  14   , in the second state, the front camera module  310  and the first camera module  321  may not overlap each other in the Z-axis direction. However, the illustrated embodiment is illustrative, and in the second state, the front camera module  310  may be located under the first camera module  321  (e.g., the +Z-axis direction). 
     In another embodiment, the plurality of rear cameras  320  may include the first camera structure  328 , the second camera module  322 , the third camera module  323 , and the fourth camera module  324 . In an embodiment, the first camera structure  328  may include the first camera module  321 , the first sensor module  325 , and the flash module  326 . 
     In another embodiment, the plurality of rear cameras  320  may be arranged in the direction perpendicular to the sliding directions D 1  and D 2  so as not to overlap the display  170  in the first state. For example, the first camera module  321 , the second camera module  322 , the third camera module  323 , and the fourth camera module  324  are disposed in a row in the direction (e.g., the −Y-axis direction) from the upper end to the lower end of the electronic device  100 . 
     In various embodiments, the first camera module  321  may have a smaller thickness than the second camera module  322 , the third camera module  323 , and the fourth camera module  324 . For example, the first camera module  321  has a smaller length in the Z-axis direction than the remaining rear camera modules, and as the first camera module  321  is disposed in a position overlapping the module accommodation part  166  of the second structure  160 , the degree to which the plurality of rear cameras  320  protrude from the rear side of the electronic device  100  may be reduced. The arrangement structure of the plurality of rear cameras  320  will be described below in more detail with reference to  FIG.  17   . 
     In another embodiment, the plurality of rear cameras  320  may be implemented with different types of camera modules. For example, the first camera module  321  is a time-of-flight (TOF) camera module. The first sensor module  325  disposed adjacent to the first camera module  321  may be a TOF transmitter TX for driving the TOF camera module. For example, the second camera module  322  is an ultra-wide camera module. For example, the third camera module  323  may be a wide camera module. For example, the fourth camera module  324  is a tele camera module. However, the types of the plurality of rear cameras  320  are not limited to the above-described examples, and various types of camera modules may be applied. 
       FIG.  15    is a sectional view of part of an electronic device according to an embodiment of the disclosure. 
       FIG.  16    is a sectional view of part of an electronic device according to an embodiment of the disclosure. 
       FIG.  15    is a sectional view of the electronic device taken along line S 3 -S 3 ′ in  FIG.  13   .  FIG.  16    is a sectional view of the electronic device taken along line S 4 -S 4 ′ in  FIG.  13   . 
     Referring to  FIGS.  15  and  16   , the electronic device  100  according to an embodiment may include the first structure  110  (e.g., the back cover  121  and the bracket  140 ), the second structure  160 , the display  170 , the display support member  193 , the battery  192 , the camera decoration member  124 , the slide circuit board  270 , the plurality of circuit boards  210 , and the plurality of rear cameras (e.g., the second camera module  322  and the fourth camera module  324 ). 
     The components of the electronic device  100  illustrated in  FIGS.  15  and  16    are identical or similar to some of the components of the electronic device  100  illustrated in  FIGS.  1  to  7 ,  8 A,  8 B, and  9  to  14   , and repetitive descriptions will be omitted. 
     In another embodiment, the back cover  121  may include a through-hole (not illustrated) into which the camera decoration member  124  is inserted. For example, the camera decoration member  124  is inserted into the through-hole of the back cover  121 , and at least part of the camera decoration member  124  may be exposed on the rear side of the electronic device  100 . The camera decoration member  124  may partially overlap the second camera module  322  and the fourth camera module  324 . Although only the second camera module  322  and the fourth camera module  324  among the plurality of rear cameras  320  are illustrated in  FIGS.  15  and  16   , the camera decoration member  124  may overlap the first camera module (e.g., the first camera module  321  of  FIGS.  13  and  14   ) and the third camera module (e.g., the third camera module  323  of  FIGS.  13  and  14   ). The camera decoration member  124  may protrude from the back cover  121  by a specified length. In various embodiments, the length by which the camera decoration member  124  protrudes from the back cover  121  may be determined by the thicknesses (e.g., the lengths in the Z-axis direction) of the plurality of rear cameras  320  and components disposed under the plurality of rear cameras  320 . 
     In another embodiment, the bracket  140  may be disposed between the back cover  121  and the second structure  160 . The bracket  140  may include the first surface  141  facing toward the second structure  160  and the second surface  142  facing toward the back cover  121 . The opening  147  vertically penetrating the first surface  141  and the second surface  142  may be formed in a partial area of the bracket  140 . At least part of the slide circuit board  270  (e.g., part of the flexible circuit board portion  273 ) may be disposed in the opening  147 . 
     In another embodiment, the second structure  160  may be disposed over the first surface  141  of the bracket  140  (e.g., the +Z-axis direction). The second structure  160  may include the third surface  164   a  on which the display  170  is disposed and the fourth surface  164   b  facing the first surface  141  of the bracket  140 . The fixed circuit board portion  271  of the slide circuit board  270  may be fixedly disposed on the fourth surface  164   b  of the second structure  160 . 
     In another embodiment, the plurality of circuit boards  210  may include the first circuit board  220  and the third circuit board  240 . The first circuit board  220  and the third circuit board  240  may be electrically connected with each other. 
     In another embodiment, the first circuit board  220  may be located between the bracket  140  and the back cover  121 . For example, the first circuit board  220  is disposed on the second surface  142  of the bracket  140 . The slide circuit board  270  and the third camera module  323  may be connected to the first circuit board  220 . For example, a connecting portion  275  (e.g., the fifth connector C 5  of  FIGS.  10  to  12   ) of the slide circuit board  270  and the second connector C 2  of the third camera module  323  are connected to the first circuit board  220  (e.g., refer to  FIGS.  9  and  13   ). 
     In another embodiment, the third circuit board  240  may be located between the bracket  140  and the fourth camera module  324 . For example, the third circuit board  240  is disposed on the second surface  142  of the bracket  140  and may be located under the fourth camera module  324  (e.g., the +Z-axis direction) (e.g., refer to  FIGS.  9  and  10   ). In an embodiment, the connecting circuit board  250  may be connected to the third circuit board  240 . At least part of the connecting circuit board  250  may be located in the space between the third circuit board  240  and the fourth camera module  324 . For example, a predetermined space in which the third circuit board  240  and the connecting circuit board  250  are disposed are provided between the fourth camera module  324  and the bracket  140 . 
     In another embodiment, the third circuit board  240  may be electrically connected with the first circuit board  220  through the eleventh connector C 11 . For example, the eleventh connector C 11  extends from the third circuit board  240  and may be connected, between the first circuit board  220  and the bracket  140 , to the first circuit board  220  (refer to panel  1402  of  FIG.  14   ). In another embodiment, the third circuit board  240  may be closer to the second surface  142  of the bracket  140  than the first circuit board  220 . For example, the first circuit board  220  is located in a higher position with respect to the bracket  140  than the third circuit board  240 . 
     In another embodiment, the slide circuit board  270  may include the fixed circuit board portion  271 , the flexible circuit board portion  273 , and the connecting portion  275  (e.g., the fifth connector C 5 ). The connecting portion  275  may make contact with the first circuit board  220 , and accordingly the slide circuit board  270  may be electrically connected with the first circuit board  220 . In various embodiments, the slide circuit board  270  may be configured such that at least some of the fixed circuit board portion  271 , the flexible circuit board portion  273 , and the connecting portion  275  are integrally formed. 
     The structure of the slide circuit board  270  illustrated in  FIG.  15    is illustrative, and the slide circuit board  270  is not limited thereto. In various embodiments, the slide circuit board  270  may not include the connecting portion  275 . For example, the slide circuit board  270  is configured such that the flexible circuit board portion  273  directly extends from, or is directly connected with, the first circuit board  220 . According to various embodiments, the slide circuit board  270  may be integrally formed with part of the first circuit board  220 . 
     In another embodiment, the fixed circuit board portion  271  may be disposed on the fourth surface  164   b  of the second structure  160 . For example, the fixed circuit board portion  271  is attached to a partial area of the fourth surface  164   b  and thus may be fixed to the second structure  160  to move together with the second structure  160 . 
     In another embodiment, the flexible circuit board portion  273  may extend from the fixed circuit board portion  271  toward the first circuit board  220 . For example, the flexible circuit board portion  273  flexibly extends from the fixed circuit board portion  271 . The flexible circuit board portion  273  may pass through part of the bracket  140  in the up/down direction or the thickness direction (e.g., the Z-axis direction) and may connect the fixed circuit board portion  271  and the first circuit board  220  facing each other with the bracket  140  therebetween. For example, the flexible circuit board portion  273  extends from the fixed circuit board portion  271  through the opening  147  of the bracket  140  to the connecting portion  275  connected to the first circuit board  220  (e.g., refer to  FIG.  11   ). 
     In another embodiment, the connecting portion  275  may include a connector (e.g., the fifth connector C 5 ). However, the structure of the connecting portion  275  is not limited to the illustrated embodiment. In various embodiments, the connecting portion  275  may be formed on a partial area of the flexible circuit board portion  273 , or may be provided in the form of a conductive pad (or, a conductive area) extending from the flexible circuit board portion  273 . 
     In another embodiment, the connecting portion  275  may be fixed to the first circuit board  220 , and the fixed circuit board portion  271  may be fixed to the second structure  160 . For example, the slide circuit board  270  is configured such that the fixed circuit board portion  271  moves in the sliding directions D 1  and D 2  with respect to the relatively fixed connecting portion  275  when the second structure  160  moves in the sliding directions D 1  and D 2  relative to the bracket  140 . The flexible circuit board portion  273  may be deformed in response to a movement of the fixed circuit board portion  271  in the state in which opposite end portions of the flexible circuit board portion  273  are connected to the fixed circuit board portion  271  and the connecting portion  275 . 
     In another embodiment, at least part of the flexible circuit board portion  273  may move together with the fixed circuit board portion  271  in the direction parallel to the sliding directions D 1  and D 2 . For example, the flexible circuit board portion  273  is formed in a bent shape in which one partial area and another partial area face each other in the direction perpendicular to the sliding directions D 1  and D 2 . For example, at least part of the flexible circuit board portion  273  may be bent one or more times in the sliding directions D 1  and D 2 . 
     In an embodiment, the flexible circuit board portion  273  may include one or more bending portions  273   b  and  273   d . For example, the flexible circuit board portion  273  includes a first extending portion  273   a  extending from the fixed circuit board portion  271  in the second direction D 2 , the first bending portion  273   b  bent from the first extending portion  273   a  in the first direction D 1 , a second extending portion  273   c  extending from the first bending portion  273   b  in the first direction D 1 , the second bending portion  273   d  bent from the second extending portion  273   c  in the second direction D 2 , and a third extending portion  273   e  extending from the second bending portion  273   d  in the second direction. In various embodiments, the flexible circuit board portion  273  may be bent to have a substantially S-shape. In various embodiments, the bending portions  273   b  and  273   d  may be formed in a substantially U-shape. 
     In another embodiment, the flexible circuit board portion  273  may be configured to be deformed as the fixed circuit board portion  271  moves. As illustrated in  FIG.  15   , the lengths of the first extending portion  273   a  and the second extending portion  273   c  that extend from opposite end portions of the first bending portion  273   b  may be increased or decreased as the fixed circuit board portion  271  moves in the first direction D 1  or the second direction D 2 . 
     For example, when the fixed circuit board portion  271  moves in the first direction D 1 , the slide circuit board  270  is deformed in a form in which the length of the first extending portion  273   a  is increased and the length of the second extending portion  273   c  is decreased. In contrast, when the fixed circuit board portion  271  moves in the second direction D 2 , the slide circuit board  270  may be deformed in a form in which the length of the first extending portion  273   a  is decreased and the length of the second extending portion  273   c  is increased. However, the shape and motion of the flexible circuit board portion  273  are not limited to the above-described example. According to various embodiments, the flexible circuit board portion  273  may be implemented in various shapes and/or structures capable of connecting the fixed circuit board portion  271  and the first circuit board  220  such that the fixed circuit board portion  271  and the first circuit board  220  are movable relative to each other. 
       FIG.  17    is a sectional view of part of the electronic device according to an embodiment of the disclosure. 
     Panel  1701  of  FIG.  17    is a sectional view of the electronic device taken along line S 5 -S 5 ′ in  FIG.  13   . Panel  1702  of  FIG.  17    is a sectional view of the electronic device taken along line S 6 -S 6 ′ in  FIG.  14   . 
     Referring to  FIG.  17   , the electronic device  100  according to an embodiment may be configured such that a camera module (e.g., the first camera module  321 ) having a relatively small thickness among the plurality of rear cameras  320  is disposed in a position overlapping the module accommodation part  166  of the second structure  160 . 
     In another embodiment, the plurality of rear cameras  320  may include the first camera module  321 , the second camera module  322 , the third camera module  323 , and the fourth camera module  324 . The first camera module  321 , the second camera module  322 , the third camera module  323 , and the fourth camera module  324  may be disposed in a row along the direction perpendicular to the sliding directions D 1  and D 2 . 
     In another embodiment, the plurality of rear cameras  320  may be configured such that the first camera module  321  has a smaller thickness than the second camera module  322 , the third camera module  323 , and the fourth camera module  324 . For example, the first camera module  321  has a first thickness T 1 , and the second camera module  322  to the fourth camera module  324  have a thickness greater than the first thickness T 1 . 
     In another embodiment, the first camera module  321  may be located adjacent to the upper end (e.g., the first side member  131 ) of the electronic device  100  and may overlap the module accommodation part  166 , which is formed on the second structure  160 , in the thickness direction (e.g., the Z-axis direction). For example, as illustrated in  FIG.  17   , the first camera module  321  may be located over the module accommodation part  166  (e.g., the −Z-axis direction) when the section of the electronic device  100  is viewed. 
     In another embodiment, the first camera module  321  may be located to overlap the front camera module  310  or the first speaker module  330 , which is disposed in the module accommodation part  166 , to correspond to a state of the electronic device  100 . For example, the first camera module  321  may overlap the first speaker module  330  in the first state (e.g., the state of  FIG.  13   ) in which the second structure  160  slides inward with respect to the bracket  140  (or, the first structure  110 ). The first camera module  321  may overlap the front camera module  310  in the second state (e.g., the state of  FIG.  14   ) in which the second structure  160  slides outward with respect to the bracket  140 . 
     In another embodiment, the second structure  160  may include the third surface  164   a  on which the display  170  is disposed and the fourth surface  164   b  facing away from the third surface  164   a . The module accommodation part  166 , in which the front camera module  310  and the first speaker module  330  are accommodated, may be formed on the fourth surface  164   b  of the second structure  160 . For example, the module accommodation part  166  may have an empty space formed therein in which the front camera module  310  and the first speaker module  330  are accommodated. Although not illustrated in  FIG.  17   , the second sensor module (e.g., the second sensor module  340  of  FIGS.  13  and  14   ) may be accommodated together in the module accommodation part  166 . 
     In another embodiment, the module accommodation part  166  may protrude or extend from the fourth surface  164   b  of the second structure  160  toward the bracket  140  by a specified length L 1 . For example, the protruding length L 1  of the module accommodation part  166  is determined in consideration of the thickness of the front camera module  310  and the thickness of the first speaker module  330 . As the module accommodation part  166  protrudes toward the bracket  140 , the separation distance L 2  between the module accommodation part  166  and the back cover  121  may be smaller than the separation distance L 3  between the fourth surface  164   b  of the second structure  160  and the back cover  121 . 
     In another embodiment, the module accommodation part  166  may extend along the sliding directions D 1  and D 2  of the second structure  160  (e.g., refer to the module accommodation part  166  of  FIG.  14   ). For example, the module accommodation part  166  is formed to overlap the first camera module  321  when the electronic device  100  is in the first state, the second state, or a state between the first state and the second state. 
     In another embodiment, when the second structure  160  slides, the module accommodation part  166  may move while maintaining a state of overlapping the first camera module  321 . As illustrated in panel  1701  of  FIG.  17   , when the electronic device  100  is in the first state, the first camera module  321  may overlap the first speaker module  330 , which is accommodated in the module accommodation part  166 , in the Z-axis direction. As illustrated in panel  1702  of  FIG.  17   , when the electronic device  100  is in the second state, the first camera module  321  may overlap the front camera module  310 , which is accommodated in the module accommodation part  166 , in the Z-axis direction. 
     In another embodiment, the degree to which the camera decoration member  124  protrudes from the back cover  121  may be determined by the protruding length L 1  of the module accommodation part  166  and the thickness T 1  of the plurality of rear cameras  320 . For example, the degree to which the camera decoration member  124  protrudes from the back cover  121  may be increased as the thickness of the plurality of rear cameras  320  overlapping the module accommodation part  166  is increased. 
     Considering that the separation distance L 2  between the module accommodation part  166  and the back cover  121  is smaller than the separation distance L 3  between the second surface  142  of the second structure  160  and the back cover  121 , the electronic device  100  according to an embodiment may be configured such that the first camera module  321  is disposed in a position overlapping the module accommodation part  166 . For example, the degree to which the plurality of rear cameras  320  (or, the camera decoration member  124 ) protrude from the rear side of the electronic device  100  is reduced by locating the first camera module  321 , which has a relatively small thickness among the plurality of rear cameras  320 , over the module accommodation part  166  (e.g., the −Z-axis direction). 
     As the first camera module  321  and the module accommodation part  166  overlap each other, a predetermined space may be formed between the remaining rear cameras  320  and the fourth surface  164   b  of the second structure  160  in the electronic device  100  according to an embodiment. For example, the thickness of the second camera module  322  to the fourth camera module  324  is smaller than the sum of the first thickness T 1  of the first camera module  321  and the protruding length L 1  of the module accommodation part  166 , and an empty space may be formed under the second camera module  322  to the fourth camera module  324 . In various embodiments, as the empty space is formed, the third circuit board  240  may be disposed under the fourth camera module  324  (e.g., refer to  FIG.  16   ). 
       FIG.  18    is a sectional view of a first circuit board of an electronic device according to an embodiment of the disclosure.

For ease of description, the same components as those described in regard to  FIG.  24    are briefly described or omitted from the description. 
     The MST communication module  710  may receive a signal containing control information or payment information such as card information from the processor  520 , generate a magnetic signal corresponding to the received signal, and then transfer the generated magnetic signal to the external electronic device  502  (e.g., a point-of-sale (POS) device) via the MST antenna  797 - 1 . To generate the magnetic signal, according to an embodiment, the MST communication module  710  may include a switching module (not shown) that includes one or more switches connected with the MST antenna  797 - 1 , and control the switching module to change the direction of voltage or current supplied to the MST antenna  797 - 1  according to the received signal.

     According to an embodiment, some of the MST antenna  797 - 1 , the NFC antenna  797 - 3 , or the wireless charging antenna  797 - 5  may share at least part of their radiators. For example, the radiator of the MST antenna  797 - 1  may be used as the radiator of the NFC antenna  797 - 3  or the wireless charging antenna  797 - 5 , or vice versa. In such a case, the antenna module  597  may include a switching circuit (not shown) adapted to selectively connect (e.g., close) or disconnect (e.g. open) at least part of the antennas  797 - 1 ,  797 - 3 , or  797 - 5 , for example, under the control of the wireless communication module  592  (e.g., the MST communication module  710  or the NFC communication module  730 ) or the power management module (e.g., the wireless charging module  750 ). For example, when the electronic device  501  uses a wireless charging function, the NFC communication module  730  or the wireless charging module  750  may control the switching circuit to temporarily disconnect at least one portion of the radiators shared by the NFC antenna  797 - 3  and the wireless charging antenna  797 - 5  from the NFC antenna  797 - 3  and to connect the at least one portion of the radiators with the wireless charging antenna  797 - 5 . 
     According to an embodiment, at least one function of the MST communication module  710 , the NFC communication module  730 , or the wireless charging module  750  may be controlled by an external processor (e.g., the processor  520 ). According to an embodiment, at least one specified function (e.g., a payment function) of the MST communication module  710  or the NFC communication module  730  may be performed in a trusted execution environment (TEE).
