The first guide member (310) may be positioned between the center bar (270) and the first wing plate (381), and the second guide member (320) may be positioned between the center bar (270) and the first wing plate (381).

[0055] According to one embodiment, the guide member (330) can rotate clockwise or counterclockwise according to the hinge operation of at least one hinge device (240, 240-1). While the first guide member (310) rotates counterclockwise, the second guide member (320) can rotate clockwise, and while the first guide member (310) rotates clockwise, the second guide member (320) can rotate counterclockwise. The first guide member (310) and the second guide member (320) can be configured to guide the movement of the FPCB (260) while rotating. The guide member (330) can guide the shape (or form) of the FPCB (260) when the FPCB (260) unfolds or folds according to the unfolding or folding operation of the foldable electronic device (200). The guide member (330) can prevent the FPCB (260) from being formed abnormally (e.g., being formed to one side or being formed asymmetrically) while rotating according to the unfolding or folding motion of the foldable electronic device (200).

[0056] FIG. 4a is a perspective view showing an FPCB according to one embodiment, and FIG. 4b is a cross-sectional view showing an unfolded state of an electronic device including the FPCB taken along line “A-A’” in FIG. 4a.

[0057] Referring to FIGS. 3, 4a, and 4b, the FPCB (260) may include a plurality of connectors (451, 452). For example, the FPCB (260) may include at least one first connector (451) formed at one end of the FPCB (260) (e.g., the end facing the +y-axis) and at least one second connector (452) formed at the other end of the FPCB (260) (e.g., the end facing the -y-axis). The at least one first connector (451) may electrically connect the FPCB (260) and the first printed circuit board (281), and the at least one second connector (452) may electrically connect the FPCB (260) and the second printed circuit board (282).

[0058] At least a portion of the FPCB (260) according to one embodiment may be formed into a curved shape to avoid interference with the hinge housing (250) and surrounding structures. At least a portion of the FPCB (260) may be formed into a predetermined curved shape by bending it in a single-piece state before the assembly process of the electronic device (200) using a pre-bending jig. For example, the FPCB (260) may include a plurality of bending portions (461, 462, 463, 464) in an area corresponding to the hinge device (240, 240-1), so that the FPCB (260) may have an extra length to accommodate a change in length according to the folding operation of the foldable electronic device (200). An FPCB (260) including a plurality of bending portions (461, 462, 463, 464) may have a restoring force to accommodate a change in length due to a folding operation of a foldable electronic device (200).

[0059] According to one embodiment, the FPCB (260) may include a flexible region (or variable region, flexible region, bending region) (460) accommodated within the hinge housing (250). The flexible region (460) may be provided to be movable within the hinge housing (250) when the foldable electronic device (200) is folded or unfolded. The shape of the flexible region (460) may be changed within the hinge housing (250) in response to the behavior of the hinge device (240, 240-1).

[0060] In one embodiment, the FPCB (260) may be folded or unfolded according to an unfolding or folding operation of the foldable electronic device (200). For example, the flexible region (460) of the FPCB (260) may be folded at least in a portion in the unfolded state of the foldable electronic device (200). For example, the flexible region (460) of the FPCB (260) may be unfolded at least in a portion in the folded state of the foldable electronic device (200).

[0061] According to one embodiment, the flexible region (460) of the FPCB (260) may be a region that forms a plurality of bending portions (461, 462, 463, 464) as the foldable electronic device (200) is converted into a folded state or an unfolded state. For example, the flexible region (460) may include a first bending portion (461) and a third bending portion (463) arranged on one side (e.g., a side facing the +y-axis) with respect to the central portion (465), and a second bending portion (462) and a fourth bending portion (464) arranged on the other side (e.g., a side facing the -y-axis) with respect to the central portion (465). The first bending portion (461) may be arranged between one side of the central portion (465) and the first connector (451) and may be bent to correspond to a folding angle of the electronic device. The second bending portion (462) may be disposed between the other side of the central portion (465) and the second connector (452) and may be bent to correspond to the folding angle of the electronic device. The second bending portion (462) may be formed symmetrically with respect to the first bending portion (461) with respect to the central portion (465) (or the z-axis). The third bending portion (463) may be disposed between the first bending portion (461) and the central portion (465) and may be bent in the opposite direction to the first bending portion (461). The fourth bending portion (464) may be disposed between the second bending portion (462) and the central portion (465) and may be bent in the opposite direction to the second bending portion (462). The fourth bending portion (464) may be formed symmetrically with respect to the third bending portion (463) with respect to the central portion (465) (or the z-axis).

[0062] According to one embodiment, the position and / or curvature of at least one of the first bending portion (461), the second bending portion (462), the third bending portion (463), and the fourth bending portion (464), and the length of the central portion (465) may vary depending on the change in the folding angle of the foldable electronic device (200). The position and / or shape (e.g., curvature) of at least one of the first bending portion (461), the second bending portion (462), the third bending portion (463), and the fourth bending portion (464), and the position and / or shape (e.g., length) of the central portion (465) may be different in an unfolded state of the electronic device (200) and a folded state of the electronic device (200).

[0063] According to one embodiment, when the folding operation of the electronic device is repeated, the flexible region (460) of the FPCB (260) is temporarily formed to be biased to one side, so that the curvature of the bending portions (461, 462, 463, 464) is reduced, and the bending stress of the bending portions (461, 462, 463, 464) with the reduced curvature is increased, which may cause damage to the FPCB (260). The guide member (330) may be arranged adjacent to the flexible region (460) of the FPCB (260) to prevent damage to the FPCB (260).

[0093] Referring to FIGS. 3 to 11, according to one embodiment, the flexible region (460) of the FPCB (260) can move along the guide member (330) when the foldable electronic device (200) is unfolded or folded. The flexible region (460) of the FPCB (260) can be disposed between the guide member (330) and the hinge housing (250). A portion of the FPCB (260) can be disposed between each of the first side wall (255) and the second side wall (256) that are parallel to the center bar (270) (or folding axis) among the plurality of side walls of the hinge housing (250) and the guide member (330). A part of the flexible region (460) of the FPCB (260) may be disposed between the first side wall (255) and the first guide member (310), and another part of the flexible region (460) of the FPCB (260) may be disposed between the second side wall (256) and the second guide member (320).

[0094] The first guide member (310) may face a part of the first flexible surface (261) of the flexible region (460) of the FPCB (260) in a first direction (e.g., +y-axis direction). The first guide member (310) facing a part of the first flexible surface (261) may limit the flexible region (460) of the FPCB (260) from moving abruptly in a second direction (e.g., -y-axis direction) opposite to the first direction. The first guide member (310) may prevent or reduce the FPCB (260) from moving in the second direction (e.g., -y-axis direction) during a folding operation of the electronic device (200). The second guide member (320) may face another part of the first flexible surface (261) of the flexible region (460) of the FPCB (260) in a second direction (e.g., -y-axis direction). The second guide member (320) facing another part of the first flexible surface (261) may limit the flexible region (460) of the FPCB (260) from moving abruptly in the first direction (e.g., +y-axis direction) which is opposite to the second direction. The second guide member (320) may prevent or reduce the FPCB (260) from moving in the first direction (e.g., +y-axis direction) during a folding operation of the electronic device (200).

[0095] When the electronic device (200) according to the embodiment is unfolded, the first guide member (310) and the second guide member (320) may rotate in response to the rotation of the first connecting member (810) and the second connecting member (820) included in the hinge device (240, 240-1). For example, the first guide member (310) may rotate clockwise in response to the first connecting member (810) rotating clockwise. The second guide member (320) may rotate counterclockwise in response to the second connecting member (820) rotating counterclockwise. According to the unfolding operation of the electronic device (200), the first guide bar (313) of the first guide member (310) and the second guide bar (323) of the second guide member (320) may rotate from the upper side toward the lower side. When the electronic device is unfolded, the flexible region (460) of the FPCB (260) can move along the first guide member (310) and the second guide member (320). The flexible region (460) of the FPCB (260) can move in a downward direction (e.g., in the -z-axis direction) toward the hinge housing (250) in a region between each of the first guide member (310) and the second guide member (320) and the hinge housing (250). A portion of the flexible region (460) of the FPCB (260) that has moved downward can be folded.

[0096] According to one embodiment, in the unfolded state of the electronic device (200), at least a portion of the flexible region (460) of the FPCB (260) may be arranged closer to the bottom surface (252) of the hinge housing (250) than the center bar (270). In the unfolded state of the electronic device (200), at least a portion of the flexible region (460) of the FPCB (260) may be arranged to contact or be adjacent to the bottom surface (252) of the hinge housing (250). In the unfolded state of the electronic device (200), a portion of the first flexible surface (261) (e.g., the surface facing the +z-axis) of the flexible region (460) of the FPCB (260) may be arranged to contact or be adjacent to the first guide bar (313) and the second guide bar (323). In the unfolded state of the electronic device (200), a portion of the second flexible surface (261) (e.g., the surface facing the +z axis) of the flexible region (460) of the FPCB (260) may be placed in contact with or adjacent to the bottom surface (252) of the hinge housing (250).

[0097] In an embodiment, when the electronic device is folded, the first guide member (310) and the second guide member (320) may rotate in response to the rotation of the first connecting member (810) and the second connecting member (820) included in the hinge device (240, 240-1). For example, the first guide member (310) may rotate counterclockwise in response to the first connecting member (810) rotating counterclockwise. The second guide member (320) may rotate clockwise in response to the second connecting member (820) rotating clockwise. Depending on the folding operation of the electronic device, the first guide bar (313) of the first guide member (310) and the second guide bar (323) of the second guide member (320) may rotate from the bottom to the top. When the electronic device is folded, the flexible region (460) of the FPCB (260) can move along the first guide member (310) and the second guide member (320). According to one embodiment, the flexible region (460) of the FPCB (260) can move upward (e.g., in the +z-axis direction) toward the center bar (270) in the region between each of the first guide member (310) and the second guide member (320) and the hinge housing (250). A portion of the flexible region (460) of the FPCB (260) that has moved upward can be unfolded. According to one embodiment, in the folded state of the electronic device, at least a portion of the flexible region (460) of the FPCB (260) can be arranged closer to the center bar (270) than to the bottom surface (252) of the hinge housing (250). In the folded state of the electronic device (200), a portion of the first flexible surface (261) (e.g., a surface facing the +z-axis) of the flexible region (460) of the FPCB (260) may be arranged in contact with or adjacent to the first guide bar (313) and the second guide bar (323). In the folded state of the electronic device (200), a portion of the second flexible surface (261) (e.g., a surface facing the +z-axis) of the flexible region (460) of the FPCB (260) may be arranged to be spaced apart from the bottom surface (252) of the hinge housing (250).

[0139] FIG. 14 is a drawing showing the behavior of a hinge device of an electronic device according to one embodiment.

[0140] Referring to FIGS. 3 to 14, according to one embodiment, the electronic device (200) can be switched in a state by a user's manipulation or an external force (EF). The user's external force (EF) can be transmitted to the first rotation member (1210), the second rotation member (1220), the first arm member (1410), and the second arm member (1420) through the first housing (210) and the second housing (220). The first rotation member (1210), the second rotation member (1220), the first arm member (1410), and the second arm member (1420) can rotate by the transmitted external force. The gear assembly (1431, 1432, 1433, 1434), the first shaft (1241) and the second shaft (1242) can rotate in conjunction with the rotating first rotating member (1210), the second rotating member (1220), the first arm member (1410) and the second arm member (1420). As the first connecting member (810) coupled to the rotating first shaft (1241) and the second connecting member (820) coupled to the second shaft (1242) rotate, the center bar (270) can move linearly.

[0141] According to one embodiment, when an external force from a user is applied to the electronic device in an unfolded state, a folding operation (or a folding operation) of the first housing (210) and the second housing (220) may be initiated. The external force (EF) from the user may be transmitted to the first rotation member (1210), the second rotation member (1220), the first arm member (1410), and the second arm member (1420) through the first housing (210) and the second housing (220). By the transmitted external force, the first rotation member (1210) and the first arm member (1410) may rotate clockwise, and the second rotation member (1220) and the second arm member (1420) may rotate counterclockwise. Part of the gear assembly (1431, 1432, 1433, 1434) and the first shaft (1241) can rotate clockwise in conjunction with the first rotating member (1210) and the first arm member (1410) that rotate clockwise. Part of the remaining gear assembly (1431, 1432, 1433, 1434) and the second shaft (1242) can rotate counterclockwise in conjunction with the second rotating member (1220) and the second arm member (1420) that rotate counterclockwise. As the first connecting member (810) coupled to the first shaft (1241) that rotates clockwise rotates clockwise, and the second connecting member (820) coupled to the second shaft (1242) that rotates counterclockwise rotates counterclockwise, the center bar (270) can descend toward the FPCB (260). At the same time, a part of the first guide member (310) coupled to the first connecting member (810) that rotates clockwise can rotate clockwise while coming into contact with the flexible region (460) of the FPCB (260), and a part of the second guide member (320) coupled to the second connecting member (820) that rotates counterclockwise can rotate counterclockwise while coming into contact with the flexible region (460) of the FPCB (260).When the electronic device is folded, the first guide member (310) and the second guide member (320) can guide the movement of the FPCB (260).

[0142] Fig. 15 is a drawing showing the behavior of a guide bracket of an electronic device according to one embodiment. In Fig. 15 <1501> is a drawing showing the unfolded state of an electronic device, <1502> is a drawing showing the operation of a guide member when the electronic device is switched from an unfolded state to a folded state. <1503> is a drawing showing the folding state of an electronic device.

[0143] Referring to FIGS. 3 to 15, when the electronic device is in an unfolded state, the center bar (270) may be raised upward (e.g., toward the +z-axis or toward the display (240)) so as to be spaced apart from the hinge housing (250) by a specified distance. The connection guide pins (814, 824) of the connection members (810, 820) coupled to the raised center bar (270) may move upward. The guide bars (313, 323) of the guide members (310, 320) coupled to the connection guide pins (814, 824) may move downward. The flexible region (460) of the FPCB (260) may move downward along the guide bars (313, 323). At least a portion of the flexible region (460) of the FPCB (260) may be positioned to contact or be adjacent to the bottom surface (252) of the hinge housing (250).

[0144] An electronic device can be switched from an intermediate state or an unfolded state to a folded state by a user's manipulation or an external force (EF). The connecting member (810, 820) and the guide member (310, 320) can rotate in response to the shaft (1241, 1242) rotating by the user's manipulation or the external force (EF). By the rotation of the connecting member (810, 820), the center bar (270) can be lowered downward (e.g., toward the side facing the -z-axis or toward the hinge housing (250)).

[0145] According to one embodiment, the first connecting member (810) and the first guide member (310) can rotate in a first rotational direction (e.g., clockwise) in response to the rotation of the first shaft (1241), and the second connecting member (820) and the second guide member (320) can rotate in a second rotational direction (e.g., counterclockwise) opposite to the first rotational direction in response to the rotation of the second shaft (1242). The first connecting guide pin (814) of the first connecting member (810) can rotate in the first rotational direction with respect to the first shaft (1241). The first connecting guide pin (814) can move from the upper side to the lower side along the first rotational direction. The first guide bar (313) of the first guide member (310) can rotate in the first rotational direction with respect to the first connecting guide pin (814). The first guide bar (313) can move from the bottom to the top along the first rotation direction. The second connection guide pin (824) of the second connection member (820) can rotate in the second rotation direction with respect to the second shaft (1242). The second connection guide pin (824) can move from the top to the bottom along the second rotation direction. The second guide bar (323) of the second guide member (320) can rotate in the second rotation direction with respect to the second connection guide pin (824). The second guide bar (323) can move from the bottom to the top along the second rotation direction. The flexible region (460) of the FPCB (260) can move upward along the first guide bar (313) and the second guide bar (323) that move upward. In the folded state of the electronic device, the flexible region (460) of the FPCB (260) can be spaced apart from the bottom surface (252) of the hinge housing (250) by a specified distance. In the folded state of the electronic device, at least a portion of the flexible region (460) of the FPCB (260) can be arranged closer to the center bar (270) than the bottom surface (252) of the hinge housing (250).

[0146] According to one embodiment, in the unfolded state of the electronic device, the first connection guide pin (814) and the second connection guide pin (824) may be positioned above the first guide bar (313) and the second guide bar (323). In the folded state of the electronic device, the first guide bar (313) and the second guide bar (323) may be positioned above the first connection guide pin (814) and the second connection guide pin (824).

[0148] Referring to FIGS. 3 and 16, an electronic device according to an embodiment (e.g., the electronic device (100) of FIG. 1, the electronic device (200) of FIGS. 2A and 2B) may include a plurality of hinge devices (240, 240-1) connecting a first housing (210) and a second housing (220) at a lower portion (e.g., in the -z-axis direction) of a display (230). For example, the plurality of hinge devices (240, 240-1) may include a first hinge device (240) and a second hinge device (240-1) spaced apart from the first hinge device (240) along a direction (e.g., in the x-axis direction) parallel to a folding axis (or, center bar (1670)). A plurality of hinge devices (240, 240-1) may be arranged between the first housing (210) and the second housing (220) so as not to be visible from the outside through a hinge housing (250) (e.g., a hinge cover). At least a portion of the plurality of hinge devices (240, 240-1) may be accommodated within an internal space (251) of the hinge housing (250).

[0149] According to one embodiment, at least one of the plurality of hinge devices (240, 240-1) may include a first rotation member (1610) coupled to the first housing (210), a second rotation member (1620) coupled to the second housing (220), a first arm member (1710) that rotates in response to the rotation of the first rotation member (1610), a second arm member (1720) that rotates in response to the rotation of the second rotation member (1620), a first shaft (1641) that is arranged along the rotational axis of the first arm member (1710), a second shaft (1642) that is arranged along the rotational axis of the second arm member (1720), and a gear assembly (1630) that allows the first housing (210) and the second housing (220) to rotate symmetrically with respect to each other.

[0150] According to one embodiment, at least one of the plurality of hinge devices (240, 240-1) may include a plurality of coupling members (1810) that secure one side of the shaft (1641, 1642). The plurality of coupling members (1810, 1820) may include a first coupling member (1810) that secures one side of the first shaft (1641) of each of the plurality of hinge devices (240, 240-1) and a second coupling member (1820) that secures one side of the second shaft (1642) of each of the plurality of hinge devices (240, 240-1). For example, at least one of the plurality of coupling members (1810, 1820) may include a shape of an E-ring.

[0151] An electronic device (200) according to one embodiment may include a center bar (1670) arranged to face a portion of a display (230). The center bar (1670) may at least partially overlap a third portion of the display (e.g., the third portion (230c) of FIG. 2A). At least a portion of the center bar (1670) may be arranged between the first hinge device (240) and the second hinge device (240-1). The center bar (1670) may support a third portion of the display (230) that is not supported by at least one of the plurality of hinge devices (240, 240-1) when the electronic device is in an unfolded state. In each of the unfolded state (open), the folded state (closed), and the intermediate state of the electronic device, the center bar (1670) may be fixed at the same position without changing its position. The center bar (1670) may be secured to the hinge housing (250) via a fastening member (e.g., a screw). The center bar (1670) may be the center of the electronic device in each of the open, closed, and intermediate states of the electronic device.

[0152] An electronic device according to an embodiment may include a guide member (330) disposed between a plurality of hinge devices. The guide member (330) may guide the shape (or form) of the FPCB (260) when the FPCB (260) is unfolded or folded according to the unfolding or folding operation of the foldable electronic device (200). The guide member (330) may prevent the FPCB (260) from being formed abnormally (e.g., being formed to one side or being formed asymmetrically) while rotating according to the unfolding or folding operation of the foldable electronic device (200). As an example, the guide member (330) may include a first guide member (310) and / or a second guide member (320). The first guide member (310) may be disposed symmetrically with the second guide member (320) with the center bar (1670) therebetween. The first guide member (310) can guide the shape of the FPCB (260) by rotating in response to the rotation of the first shaft (1641). The second guide member (320) can guide the shape of the FPCB (260) by rotating in response to the rotation of the second shaft (1642).

In Fig. 17, the description may be centered on the first coupling member (1810), and the description thereof may be applied to the description of the second coupling member having the same configuration as all or part of the first coupling member (1810). For example, the description of the first coupling base (1811), the first coupling opening (1812), the first coupling guide pin (1814) (or the third guide pin (1814)), and the first coupling rib (1816) included in the first coupling member (1810) may be applied to the description of the second coupling base (1821), the second coupling opening (1822), the second coupling guide pin (1824) (or the fourth guide pin (1824)), and the second coupling rib (1826) included in the second coupling member (1820). The configuration of the guide members (310, 320) of FIGS. 16 and 17 is the same as all or part of the configuration of the guide members (310, 320) of FIGS. 3 to 15, so the description of the guide members (310, 320) of FIGS. 3 to 15 can be applied to the description of the guide members (310, 320) of FIGS. 16 and 17.

[0156] Referring to FIGS. 16 and 17, according to one embodiment, when assembling an electronic device, a first coupling member (1810) may be coupled with a first guide member (310), and a second coupling member (1820) may be coupled with a second guide member (320).

[0157] According to one embodiment, the first coupling member (1810) may include a first coupling base (1811) including a first coupling opening (1812). The first coupling opening (1812) may be formed in the form of a hole in which a portion of a side surface of the first coupling base (1811) perpendicular to the thickness direction of the first coupling base (1811) is opened while penetrating a portion of the first coupling base (1811) in the thickness direction (e.g., x-axis direction) of the first coupling base (1811). According to one embodiment, a first shaft (1641) of a hinge device (1240, 1240-1) may be inserted into the first coupling opening (1812), and a second shaft (1642) of a hinge device (240, 240-1) may be inserted into the second coupling opening (1822) of the second coupling member (1820).

As an example, the protruding length (e.g., length in the x-axis direction) of the first coupling guide pin (1814) may be formed to be greater than the depth of the first coupling opening (1812).

[0159] According to one embodiment, the first coupling member (1810) may include a first coupling rib (1816) protruding from a first coupling guide pin (1814). The protruding direction of the first coupling rib (1816) and the protruding direction of the first coupling guide pin (1814) may be different. For example, the protruding direction of the first coupling rib (1816) may be perpendicular to the protruding direction of the first coupling guide pin (1814).

[0160] According to one embodiment, the first guide member (310) can be coupled to the first coupling member (1810) in a fitting manner, thereby preventing misassembly of the first guide member (310). The first coupling rib (1816) of the first coupling member (1810) can be fitted into the first rib opening (316) of the first guide member (310). The first coupling rib (1816) of the first coupling member (1810) is inserted into the first rib opening (316) of the first guide member (310), and at least a portion of the first coupling guide pin (1814) of the first coupling member (1810) can be inserted into the first pin opening (315) of the first guide member (310).

[0161] According to one embodiment, the second guide member (320) can be coupled to the second coupling member (1820) in a fitting manner, thereby preventing misassembly of the second guide member (320). The second coupling rib (1826) of the second coupling member (1820) can be fitted into the second rib opening (326) of the second guide member (320). The second coupling rib (1826) of the second coupling member (1820) is inserted into the second rib opening (326) of the second guide member (320), and at least a portion of the second coupling guide pin (1824) of the second coupling member (1820) can be inserted into the second pin opening (325) of the second guide member (320).

[0162] According to one embodiment, the first guide member (310) may be coupled to the first connecting member (1810) via an adhesive (not shown), and the second guide member (320) may be coupled to the second connecting member (1820) via an adhesive (not shown). The guide members (310, 320) may be attached to the connecting members (810, 820) via an adhesive, thereby eliminating a shaking phenomenon due to assembly tolerance or clearance, thereby ensuring high reliability.

[0163] According to one embodiment, the first coupling member (1810) into which the first shaft (1641) is inserted can rotate with respect to the first shaft (1641) in response to the rotation of the first shaft (1641). The first guide bar (313) of the first guide member (310) into which the first coupling guide pin (1814) of the first coupling member (1810) is inserted can rotate with respect to the first coupling guide pin (1814) in response to the rotation of the first coupling guide pin (1814).

[0165] Referring to FIG. 18, according to one embodiment, the flexible region (460) of the FPCB (260) may be disposed between the guide member (330) and the hinge housing (250). The flexible region (460) of the FPCB (260) may move along the guide bar (313, 323) of the guide member (330) when the foldable electronic device (200) is unfolded or folded. The first guide member (310) may limit the flexible region (460) of the FPCB (260) from moving abruptly in a first direction (e.g., in the -y-axis direction). The first guide member (310) may prevent or reduce the FPCB from moving in the first direction (e.g., in the -y-axis direction) when the electronic device is folded. The second guide member (320) can limit the flexible region (460) of the FPCB (260) from moving rapidly in the second direction (e.g., the +y-axis direction). The second guide member (320) can prevent or reduce the FPCB (260) from moving in the second direction (e.g., the +y-axis direction) during a folding operation of the electronic device.

[0166] In a folding operation of an electronic device according to an embodiment, the coupling member (1810, 1820) and the guide member (310, 320) can rotate in response to the rotation of the shaft (1641, 1642) of the hinge device (240, 240-1). The center bar (1670) can be fixed to the hinge housing (250) regardless of the rotation of the shaft (1641, 1642) and the coupling member (1810, 1820). The position of the center bar (1670) can be fixed regardless of a change in the folded or unfolded state of the electronic device (100).

[0167] According to one embodiment, while the electronic device changes from an unfolded state to a folded state, the first coupling member (1810) and the first guide member (310) can rotate in a first rotational direction (e.g., clockwise) in response to the rotation of the first shaft (1641). The first guide bar (313) of the first guide member (310) can move upward (e.g., toward the +z-axis) in a direction closer to the second guide bar (323) along the first rotational direction. The second coupling member (1820) and the second guide member (320) can rotate in a second rotational direction (e.g., counterclockwise) opposite to the first rotational direction in response to the rotation of the second shaft (1642). The second guide bar (323) of the second guide member (320) can move upward in a direction closer to the first guide bar (313) along the second rotational direction. The flexible region (460) of the FPCB (260) can move along the first guide bar (313) and the second guide bar (323) that are brought closer. The flexible region (460) of the FPCB (260) can move upward toward the center bar (1670) in the region between each of the first guide member (310) and the second guide member (320) and the hinge housing (250). In the folded state of the electronic device, at least a portion of the flexible region (460) of the FPCB (260) can be arranged closer to the center bar (270) than to the bottom surface (252) of the hinge housing (250).

[0168] According to one embodiment, while the electronic device changes from a folded state to an unfolded state, the first coupling member (1810) and the first guide member (310) can rotate in a second rotational direction in response to the rotation of the first shaft (1641). The first guide bar (313) of the first guide member (310) can move downward in a direction away from the second guide bar (323) along the second rotational direction. The second coupling member (1820) and the second guide member (320) can rotate in the first rotational direction in response to the rotation of the second shaft (1642). The second guide bar (323) of the second guide member (320) can move downward in a direction away from the first guide bar (313) along the first rotational direction. The flexible region (460) of the FPCB (260) can move along the moved first guide bar (313) and second guide bar (323). The flexible region (460) of the FPCB (260) can move downward toward the hinge housing (250) in the region between each of the first guide member (310) and the second guide member (320) and the hinge housing (250). In the unfolded state of the electronic device, at least a portion of the flexible region (460) of the FPCB (260) can be arranged closer to the bottom surface (252) of the hinge housing (250) than the center bar (270). In the unfolded state of the electronic device, at least a portion of the flexible region (460) of the FPCB (260) can be arranged to contact or be adjacent to the bottom surface (252) of the hinge housing (250).

[0169] According to one embodiment, while the electronic device changes from an unfolded state to a folded state, the first coupling guide pin (1814) of the first coupling member (1810) can rotate clockwise about the first shaft (1641) in response to the rotation of the first shaft (1641). The first coupling guide pin (1814) of the first coupling member (1810) can move from the upper side (or one side) to the lower side (or the other side) in the clockwise direction. The first guide bar (313) of the first guide member (310) can rotate clockwise about the first coupling guide pin (1814). The first guide bar (313) can move from the lower side to the upper side in the clockwise direction. The second coupling guide pin (1824) of the second coupling member (1820) can rotate counterclockwise about the second shaft (1642). The second coupling guide pin (1824) can move from the top to the bottom in a counterclockwise direction. The second guide bar (323) of the second guide member (320) can rotate counterclockwise with respect to the second connection guide pin (824).
