In the state, it is possible to provide visual information through a portion of the second structure 102 .

According to various embodiments, one end of the roller 151 may be rotatably coupled to the second sidewall 123b, and the other end may be rotatably coupled to the third sidewall 123c. For example, the roller 151 is mounted on the second structure 102, and the rotation axis R perpendicular to the sliding movement direction of the first structure 101 (eg, the direction of arrow ① in FIG. 1A or FIG. 1B) can be rotated around The rotation axis R is disposed substantially parallel to the first sidewall 123a and may be located far from the first sidewall 123a, for example, at one edge of the second plate 121a.

Insert / take out operation can be smooth.

According to various embodiments, the support sheet 153 may be made of a material having flexibility and a certain degree of elasticity, for example, a material including an elastic body such as silicone or rubber. It may be mounted or attached to the roller 151 and selectively wound around the roller 151 as the roller 151 rotates (may be wound). In the illustrated embodiment, the support sheet 153 may be arranged in plurality (eg, four) along the rotation axis R of the roller 151 . For example, the plurality of support sheets 153 may be mounted on the roller 151 at a predetermined interval from other adjacent support sheets 153 , and may extend in a direction perpendicular to the rotation axis R. In other embodiments, one support sheet may be mounted or attached to roller 151 . For example, one support sheet may have a size and shape corresponding to an area in which the support sheets 153 are disposed and an area between the support sheets 153 in FIG. 1C . In this way, the number, size, or shape of the support sheets 153 may be appropriately changed according to the product actually manufactured. In some embodiments, the support sheet 153 is rolled on the outer circumferential surface of the roller 151 as the roller 151 rotates or deviates from the roller 151 in the form of a flat plate between the display 103 and the third plate 121c. can unfold In other embodiments, the support sheet 153 may be referred to as a “support belt”, “auxiliary belt”, “support film” or “auxiliary film”.

The support sheet 153 is generally disposed in contact with the articulated hinge structure 113 , but a portion rolled on the roller 151 may be substantially separated from the articulated hinge structure 113 .

According to various embodiments, the distance between the surface of the display 103 and the inner surface of the edge of the second plate 121a may be different depending on the extent to which the support sheet 153 is wound around the roller 151 . The smaller the distance, the easier it is to prevent foreign substances from entering, but if the distance is too small, the display 103 may contact or rub against the second plate 121a. When direct contact or friction occurs, the surface of the display 103 may be damaged or the sliding operation of the first structure 101 may be hindered.

According to various embodiments, the support sheet 153 is wound around the roller 151 in the closed state, so that the surface of the display 103 maintains a state not in contact with the second plate 121a, while the display 103 is It is possible to reduce the gap between the surface of the second plate 121a and the inner surface of the edge of the second plate (121a). For example, in the closed state, it is possible to reduce an arrangement interval to prevent foreign substances from flowing into the interior of the second structure 102 . In one embodiment, as the first structure 101 (eg, the first plate 111a or the slide plate) gradually moves to an open state, the support sheet 153 moves away from the roller 151 and gradually moves to the second structure 102 . ) (eg, the second plate 121a or the third plate 121c) and the multi-joint hinge structure 113 . For example, as the first structure 101 moves to the open state, the arrangement interval gradually increases to suppress direct friction or contact between the display 103 and other structures (eg, the second plate 121a), and friction or contact Accordingly, it is possible to prevent the surface of the display 103 from being damaged. In some embodiments, the thickness of the support sheet 153 may gradually increase from one end (eg, a portion fixed to the roller 151) to the other end (eg, a portion fixed to the first plate 111a). . By using the thickness profile of the support sheet 153, the spacing between the closed state and the open state can be adjusted.

When the first structure 101 reaches the open state, the first elastic member 131 may contact the inner side surface of the edge of the second plate 121a. For example, in the open state, the first elastic member 131 may seal the gap between the inner edge surface of the second plate 121a and the surface of the display 103 . In another embodiment, when moving from the closed state to the open state, the first elastic member 131 may move (eg, slide contact) while in contact with the second plate 121a. For example, if the foreign material is introduced into the gap between the second area A2 and the second plate 121a in the closed state, when moving to the open state, the first elastic member 131 removes the foreign material to the second structure (102) can be discharged to the outside.
