The supporting unit 6 can support the rear surface 301-2 of the display 301, that is, the opposite surface of the image display surface 301-1. In the embodiment of the present invention, the supporting unit 6 may support at least one of the opposite edges 301a and 301b of the display 301 in the width direction A2. According to the present invention, the supporting unit 6 may include a first supporting member 6-1 and a second supporting member 6-2 for supporting the edges 301a and 301b of the display 301, respectively.

5-7, in the closed state, the first supporting member 6-1 and the second supporting member 6-2 are accommodated in the first body 101 and 201. When the first body 101 When and 201 are separated from the second body 401, as illustrated in FIGS. 1 to 4, the first support member 6-1 and the second support member 6-2 enable the display 301 to unfold from the first body 101 and 201 to be located on the display The rear surface of 301 is located at 301-2 and supports edges 301a and 301b.

In the embodiment of the present invention, the supporting unit 6 is described. FIG. 11 is an exploded perspective view of a rotatable display device employing a supporting unit 6 according to an embodiment of the present invention. Fig. 12 is a front view of the rotatable display device of Fig. 11 in a partially opened state. Fig. 13 is a front view of the rotatable display device of Fig. 11 in an open state. Fig. 14 is a front view of the rotatable display device of Fig. 11 in a closed state. In FIGS. 11 to 14, the first body 101 and 201 show that the inside can be seen from the outside by omitting a partial casing.

Referring to FIGS. 11-14, the supporting unit 6 may include a first supporting member 6-1 and a second supporting member 6-2 for supporting the edges 301a and 301b of the display 301, respectively. The first support member 6-1 and the second support member 6-2 are in the form of a chain having a plurality of segmented links 601 pivotally connected to each other. The first support member 6-1 may include a pair of first chains 603 and 623 accommodated in the first bodies 101 and 201. The second supporting member 6-2 may include a pair of second chains 605 and 625 received in the first bodies 101 and 201, respectively. Each of the first chains 603 and 623 and each of the second chains 605 and 625 are in the form of chains having segmented links 601 pivotally connected to each other. Among the segment links 601 of the first chains 603 and 623 and the second chains 605 and 625, the leading links 603a, 605a, 623a, and 625a at the second body 401 are connected to the second body 401. Each of the first support member 6-1 and the second support member 6-2 may be one or one located at the center portion of each of the first support member 6-1 and the second support member 6-2 Multiple segment links (for example, The segment links 603a and 605a or 623a and 625a) are fixed to a single chain of the second body 401. The embodiments of the first supporting member 6-1 and the second supporting member 6-2 of the present invention are described below with reference to FIGS. 16 and 17.

The first and second accommodating units for accommodating the first supporting member 6-1 and the second supporting member 6-2 are respectively provided at the first body 101 and 201. For example, the first accommodating unit 151 and the second accommodating unit 152 for accommodating the first chain 603 and the second chain 605 are provided at the first body 101. The first accommodating unit 151 and the second accommodating unit 152 may be in the form of grooves extending in the width direction A2 of the display 301, for example. The first accommodating unit 151 and the second accommodating unit 152 are positioned separately from each other in the length direction A1. Similarly, the first accommodating unit 251 and the second accommodating unit 252 for accommodating the first chain 623 and the second chain 625 are provided at the first body 201. The first accommodating unit 251 and the second accommodating unit 252 may be in the form of grooves extending in the width direction A2 of the display 301, for example. The first accommodating unit 251 and the second accommodating unit 252 may be positioned separately from each other in the length direction A1.

The first sprocket and the second sprocket for transferring the first supporting member 6-1 and the second supporting member 6-2 into/out of the first bodies 101 and 201 may be provided in the first bodies 101 and 201. The first sprocket and the second sprocket are positioned adjacent to the edges 301 a and 301 b of the display 301. For example, the first sprocket 195 and the second sprocket 196 for moving the first chain 603 and the second chain 605 respectively are provided at the first body 101. The first chain 603 and the second chain 605 are conveyed by the first sprocket 195 and the second sprocket 196 in the width direction A2 inside the first body 101 and in the length direction A1 outside the first body 101. In other words, the conveying directions of the first chain 603 and the second chain 605 are changed by the first sprocket 195 and the second sprocket 196. To this end, the first sprocket 195 and the second sprocket 196 are supported in the first body 101 to surround the The rotation axes 195a and 196a of the surface 301-1 are rotatable. In other words, the rotation axes 195a and 196a are perpendicular to the length direction A1 and the width direction A2. The first sprocket 195 and the second sprocket 196 are arranged with an interval 187 in the longitudinal direction A1 to respectively correspond to the first accommodating unit 151 and the second accommodating unit 152. Therefore, the first chain 603 and the second chain 605 can be accommodated in the first body 101 to be offset from each other in the length direction A1. Since the first chain 603 and the second chain 605 do not interfere with each other, the length in the width direction A2 of the first body 101 accommodating the first chain 603 and the second chain 605 can be reduced.

Similarly, the first sprocket 295 and the second sprocket 296 for conveying the first chain 623 and the second chain 625 are provided in the first body 201. The first chain 623 and the second chain 625 are conveyed by the first sprocket 295 and the second sprocket 296 in the width direction A2 inside the first body 201 and in the length direction A1 outside the first body 201. In other words, the conveying directions of the first chain 623 and the second chain 625 are changed by the first sprocket 295 and the second sprocket 296. To this end, the first sprocket 295 and the second sprocket 296 are supported in the first body 201 so as to be rotatable about rotation axes 295a and 296a perpendicular to the image display surface 301-1. In other words, the rotation axes 295a and 296a are perpendicular to the length direction A1 and the width direction A2. The first sprocket 295 and the second sprocket 296 are arranged with an interval 287 in the longitudinal direction A1 to correspond to the first accommodating unit 251 and the second accommodating unit 252, respectively. Therefore, the first chain 623 and the second chain 625 may be accommodated in the first body 201 to be offset from each other in the length direction A1. Since the first chain 623 and the second chain 625 do not interfere with each other, the length in the width direction A2 of the first body 201 accommodating the first chain 623 and the second chain 625 can be reduced.

The sprockets 195, 196, 295, and 296 may have, for example, a polygonal shape. The length of one side of the polygon can be judged by considering the length of each of the segment links 601 set. For example, the length of one side of the polygon can be determined by considering the interval between the hinge shafts 653 of FIG. 16 of two adjacent segment links 601. In the present invention, although the sprockets 195, 196, 295, and 296 having a rectangular shape are used, the present invention is not limited thereto.

In the closed state, the first supporting member 6-1 and the second supporting member 6-2 are accommodated in the first accommodating unit 151 and the second accommodating unit 152 provided in the first body 101 and 201 of FIG. In the accommodating unit 251 and the second accommodating unit 252. In this state, when the first body 101 and 201 are separated from the second body 401, the first supporting member 6-1 and the second supporting member 6-2 are spread out from the first body 101 and 201 to be in the first body 101 and 201 extend between the second body 401. FIG. 15 illustrates the procedure of expanding the first supporting member 6-1 and the second supporting member 6-2 from the first bodies 101 and 201. Referring to operation 1211 of FIG. 15, when the first bodies 101 and 201 are separated from the second body 401 in the length direction A1, tensile force is applied to the first support member 6-1 and the second support member 6-2 in the length direction A1. This is because the guide links 603a, 605a, 623a, and 625a are connected to the second body 401. Then, the first supporting member 6-1 and the second supporting member 6-2 expand outward from the first bodies 101 and 201. As the first support member 6-1 and the second support member 6-2 expand outward from the first body 101 and 201, the sprockets 195, 196, 295, and 296 are mounted on the first support member 6-1 and the second support member 6-2 Rotate in the unfolding direction, as illustrated in operations 1212, 1213, and 1214 in FIG. 15. The direction in which the first support member 6-1 and the second support member 6-2 move in the width direction A2 inside the first body 101 and 201 is changed from the sprockets 195, 196, 295, and 296 to the length direction A1 to change from the first The main bodies 101 and 201 expand outward, as illustrated in FIG. 12. Therefore, the first body 101 and 201 can be separated from the second body 401. When the open state is reached, as illustrated in FIG. 13, the first supporting member 6-1 and the second supporting member 6-2 expand in the length direction A1 to respectively support the display 301 The edges 301a and 301b extending between the first body 101 and 201.

The first support member 6-1 and the second support member 6-2 are in the form of a chain having a segmented link 601 pivotally connected to each other but whose pivot angle is restricted. In other words, although the segment link 601 is not prevented from pivoting in one direction to wind around the sprockets 195, 196, 295, and 296, the segment link 601 no longer pivots in the unfolded state.

16 and 17 are front views of the first supporting member 6-1 and the second supporting member 6-2. Referring to FIG. 16, the first support member 6-1 is in the form of a chain in which adjacent segment links 601 are connected to each other to be pivotable about a hinge axis 653. The hinge axis 653 is an axis perpendicular to the image display surface 301-1. In other words, the hinge axis 653 is an axis perpendicular to the longitudinal direction A1 and the width direction A2. Therefore, the first supporting member 6-1 is a chain that is bendable on the plane containing the display 301. The segment links 601 are connected to each other to be pivotable in one direction between the expanded state and the bent state. The pivoting of the first support member 6-1 in the expansion direction 658 is restricted. To this end, a stopper 601a for restricting the pivoting of the first support member 6-1 is provided in the segment link 601. When the segment link 601 expands, the adjacent stoppers 601a contact each other, so that the pivoting of the first support member 6-1 in the expansion direction 658 is restricted. Therefore, as illustrated in FIG. 1, the edge 301a of the display 301 that expands from the first body 101 and 201 may be supported by the first supporting member 6-1. The center 655 of the hinge shaft 653 is displaced from the center 654 of the segment link 601 by an interval 656 in the expansion direction 658. Therefore, the first support member 6-1 can be easily bent in the direction 657, and the pivoting of the first support member 6-1 in the expansion direction 658 is restricted, so that the first support member 6-1 can be stably maintained in the expansion direction. status.

Referring to Figure 17, the second supporting member 6-2 is connected by adjacent segmented links 601 To each other in the form of a chain pivotable about a hinge axis 653 perpendicular to the image display surface 301-1. Therefore, the second supporting member 6-2 is a chain that is bendable on the plane containing the display 301. The segment links 601 are connected to each other to be pivotable in one direction between the straightened state and the bent state. The pivoting of the second support member 6-2 in the expansion direction 657 is restricted. To this end, a stopper 601a for restraining the pivoting of the second support member 6-2 is provided in the segment link 601. When the segment link 601 expands, the adjacent stoppers 601a contact each other, so that the pivoting of the second support member 6-2 in the expansion direction 657 is restricted. Therefore, as illustrated in FIG. 1, the edge 302a of the display 301 spreading outward from the first body 101 and 201 can be supported by the second supporting member 6-2. The center 655 of the hinge shaft 653 is displaced from the center 654 of the segment link 601 by an interval 656 in the expansion direction 657. Therefore, the second support member 6-2 can be easily bent in the direction 658, and the pivoting of the second support member 6-2 in the expansion direction 657 is restricted, so that the second support member 6-2 can be stably maintained in the expansion direction. status.

In the open state of FIG. 13, when the first bodies 101 and 201 approach the second body 401, the compressive force in the longitudinal direction A1 is applied to the first supporting member 6-1 and the second supporting member 6-2. Then, the first supporting member 6-1 and the second supporting member 6-2 are pushed toward the first bodies 101 and 201. The sprockets 195, 196, 295, and 296 pushed by the first support member 6-1 and the second support member 6-2 are transferred to the first body 101 at the first support member 6-1 and the second support member 6-2 And 201 in the direction of the rotation. The conveying direction of the first support member 6-1 and the second support member 6-2 is changed from the longitudinal direction A1 to the width direction A2 from the sprockets 195, 196, 295, and 296, and therefore the first support member 6-1 and the second support member 6-1 The supporting member 6-2 is accommodated in the accommodation units 151, 152, 251, and 252. When the closed state is reached, as illustrated in FIG. 14, the first supporting member 6-1 and the second supporting member 6-2 are completely contained in the first bodies 101 and 201. As above As described in the text, the display 301 is accommodated in the first bodies 101 and 201 by winding around the rollers 103 and 203.

According to the above structure, the edges 301a and 301b of the display 301 that spread out from the first body 101 and 201 are supported by the first support member 6-1 and the second support member 6-2, and therefore the display 301 can be maintained flat on Open state.

In the case where the support member is wound around the drum together with the display, the diameter of the drum including the display and the support member is increased, and therefore the first bodies 101 and 201 can be increased. According to the embodiment of the present invention, since the first supporting member 6-1 and the second supporting member 6-2 are separately accommodated in the first bodies 101 and 201 from the display 301, the sizes of the first bodies 101 and 201 are compared to The structure in which the supporting member is wound around the drum together with the display can be reduced.

Furthermore, for the structure in which the supporting member is wound around the drum together with the display, the pivot axis of the segment link forming the supporting member is the width direction of the display. The support member having the above structure is extremely weak under external force in a direction perpendicular to the image display surface of the display. According to the embodiment of the present invention, since the hinge axis 653 of the segment link 601 forming the first support member 6-1 and the second support member 6-2 is perpendicular to the image display surface 301-1, the first support member 6- 1 and the second supporting member 6-2 have strong resistance to external force applied to the display 301 in a direction perpendicular to the image display surface 301-1. Therefore, the display 301 can be stably maintained in a flat state.

The pivoting directions of the segment links 601 of the first support member 6-1 and the second support member 6-2 are opposite to each other. Therefore, due to the pivoting around the hinge shaft 653 in the opposite direction, the first support member 6-1 and the second support member 6-2 are expanded from the first body 101 and 201 in a state where the first support member 6- 1 and the second supporting member 6-2 are constrained, so the display 301 can be stably maintained in the open state.

Fig. 18 is a plan view of the rotatable display device of Fig. 11 in an open state. Referring to FIG. 18, in order to hold the display 301 flat, the display 301 needs to be maintained in a state of contacting the first support member 6-1 and the second support member 6-2. When the display 301 is lifted from the first support member 6-1 and the second support member 6-2, the display 301 may be difficult to be maintained flat. To this end, a connection structure that connects the display 301 and the support unit 6 to prevent the display 301 from lifting from the support unit 6 can be used in a rotatable display device.

Fig. 19 is an exploded perspective view of a connection structure according to an embodiment of the present invention. Fig. 20 is a rear perspective view of the connection structure of Fig. 19. FIG. 21 is a cross-sectional view taken along the line CC ′ of FIG. 20. 22A and 22B are conceptual diagrams illustrating a procedure for connecting the connecting member and the supporting unit 6 to each other. FIG. 23A is a perspective view illustrating a state where the display 301 is wound around the rollers 103 and 203. Although FIGS. 19 to 23A illustrate the connection structure between the first support member 6-1 and the display 301, the connection structure between the second support member 6-2 and the display 301 is similar to the first support member 6-1 and the display 301 The connection structure is the same. Therefore, in FIGS. 19 to 23A, the reference numbers used to describe the connection structure between the second support member 6-2 and the display 301 are indicated in parentheses.

Referring to FIGS. 19 to 23A, a plurality of connecting members 701 are coupled to the edges 301a and 301b of the display 301. The connecting member 701 may be, for example, a clip type. The distance at which the connecting member 701 is arranged along the edges 301a and 301b of the display 301 may be constant or may not be constant. In an example, the spacing of the connecting parts 701 may be the same as the spacing between the segment links 601. In another example, the distance between the connecting members 701 can be increased closer to the second body 401, and can be decreased closer to the rollers 103 and 203. When the display 301 is wound around the drum 103 and 203 relatively many times The length of the indicator 301 wrapped around the rollers 103 and 203 once is longer than the length of the display 301 wrapped around the rollers 103 and 203 once when the display 301 is wrapped around the rollers 103 and 203 relatively few times. In consideration of the above, the pitch of the connecting member 701 can be determined so that when the display 301 is wound around the rollers 103 and 203, the connecting member 701 can be aligned in the radial direction at a plurality of positions in the circumferential direction. In other words, when the display 301 is wound around the rollers 103 and 203, as illustrated in FIG. 23A, the position of the connecting member 701 in the circumferential direction is arranged in a straight line along the radial direction. According to the above structure, when the display 301 is wound around the drums 103 and 203, the image display surface 301-1 and the rear surface 301-2 are separated from each other by a certain interval. Therefore, when the display 301 is wound around the rollers 103 and 203 or spread out from the rollers 103 and 203, the image display surface 301-1 is damaged due to the friction between the image display surface 301-1 and the rear surface 301-2 The possibility can be reduced.

Referring to FIG. 23A, the connecting member 701 may include a protruding portion 701c and a concave portion 701d recessed on the opposite side of the protruding portion 701c. When the position of the connecting member 701 in the circumferential direction is aligned in a straight line along the radial direction, the protruding portion 701c of the connecting member 701-1 positioned outward in the radial direction can be inserted inward of the connecting member 701-2 Positioned in the recessed portion 701d. Therefore, the connecting member 701-1 and the connecting member 701-2 can be arranged in the radial direction without deviation in the longitudinal direction A1 of the display 301. Therefore, the connection member 701 can be stably aligned in the radial direction.

Referring to FIG. 21, each of the connecting parts 701 may include a fixing part 701a to which the edge 301a or 301b of the display 301 is fixed and a first connecting part 701b stepped from the fixing part 701a. The first connecting portion 701b is coupled to the second connecting portion 601b, which is disposed on the forming the first supporting member 6-1 and the second supporting member 6-2 At each of the segment links 601. For example, the first connecting portion 701b has a protruding shape, and the second connecting portion 601b has a shape of an insertion groove into which the first connecting portion 701b is inserted, or vice versa. The insertion groove may have a shape cut in the length direction A1. Even when the pitch of the connecting portions 701 is not constant, the first connecting portion 701b can still be easily coupled to the second connecting portion 601b. According to the above structure, as the first connection portion 701b is coupled to the second connection portion 601b, the display 301 can be stably supported without being separated from the first support member 6-1 and the second support member 6-2, This is maintained flat.

22A is a schematic plan view of FIG. 20, that is, it shows the rollers 103 and 203 and the first support member 6-1 and the second support member 6-2 in the direction along the rotation axis 103a and 203a of the roller 103 and 203 Check the view 1001. FIG. 22B is a schematic rear view of FIG. 20, that is, the rollers 103 and 203, and the first support member 6-1 and the second support member 6-2 are shown moving along the rotation axis of the sprockets 195, 196, 295, and 296 View 1003 viewed in the directions of 195a, 196a, 295a, and 296a. Referring to FIGS. 20-22B, the procedure for coupling the connecting member 701 and the segment link 601 to each other until the display 301 expands outward from the rollers 103 and 203 is described.

As described above, the rotation axes 195a, 196a, 295a, and 296a of the sprockets 195, 196, 295, and 296 are perpendicular to the rotation axes 103a and 203a of the drums 103 and 203. The first support member 6-1 and the second support member 6-2 move in the width direction A2 in the first bodies 101 and 201, and the movement direction of the first support member 6-1 and the second support member 6-2 is changed by The sprockets 195, 196, 295, and 296 are changed to the length direction A1. Therefore, the segment links 601 on the sprockets 195, 196, 295, and 296 have moved in the longitudinal direction A1 parallel to the display 301. Conceptually, the rollers 103 and 203 and the sprockets 195, 196, 295 and 296 are connected to each other in the form of helical gears to The indicator 301 and the first support member 6-1 and the second support member 6-2 are connected to each other.

In FIGS. 22A and 22B, when the first body 101 and 201 move away from the second body 401, the display 301 expands outward from the rollers 103 and 203 and moves in the length direction A1. In this state, the first support member 6-1 and the second support member 6-2 move in the width direction A2, and then the movement direction of the first support member 6-1 and the second support member 6-2 is changed by the sprocket 195, 196, 295, and 296 are changed to the length direction A1. During the change of the moving direction, that is, while the segment link 601 is rotated by being connected to the sprockets 195, 196, 295, and 296, the interval between the segment link 601 and the display 301 is as shown in the view 1001 of FIG. 22A The illustrated arrows 1013, 1014, and 1015 gradually decrease. Likewise, the intervals between the edges 301a and 301b of the display 301 and the segment link 601 gradually decrease as indicated by arrows 1021, 1022, and 1023 illustrated by the view 1003 of FIG. 22B. Although the segmented link 601 connected to the first sprockets 195 and 295 and the second sprockets 196 and 296 approach the display 301 by changing its moving direction, as illustrated in FIGS. 20 and 21, the connection member 701 The first connecting portion 701b is sequentially coupled to the second connecting portion 601b of each segmented link in sequence 601, and the display 301 and the segmented link 601 are expanded outward from the first bodies 101 and 201. According to the above structure, the display 301 can be stably supported without being separated from the first supporting member 6-1 and the second supporting member 6-2, and therefore the display 301 that expands outward from the first bodies 101 and 201 can be Maintain flat.

When the first body 101 and the second body 201 approach the second body 401, the segment link 601 connected to the sprockets 195, 196, 295, and 296 changes the moving direction from the length direction A1 to the width direction A2. In the procedure, the segmented link 601 is gradually separated from the edges 301a and 301b of the display 301, and the first connecting part 701b and The second connection portion 601b is separated. The display 301 is accommodated in the first bodies 101 and 201 by being wound around the rollers 103 and 203. The first support member 6-1 and the second support member 6-2 are accommodated in the accommodation units 151, 152, 251 and 252.

In FIG. 23A, a protruding portion 701c having a regular parallelepiped shape and a concave portion 701d corresponding to the protruding portion 701c and having an open side in the width direction A2 are used as structures to prevent separation in the radial direction. The sliding of the connecting parts 701-1 and 701-2 positioned outwardly and inwardly in the length direction A1 aligns with the connecting parts 701-1 and 701-2. However, the shapes of the protruding portion 701c and the concave portion 701d are not limited to the shapes illustrated in FIG. 23A. 23B to 23H illustrate various shapes of the protruding portion 701c and the recessed portion 701d.

Referring to FIG. 23B, the protruding portion 701c and the concave portion 701d may have a circular convex shape and a circular concave shape closed in the length direction A1 and the width direction A2, respectively. Referring to FIG. 23C, the protruding portion 701c and the concave portion 701d may have an angular shape (cone or pyramid shape) and a concave shape closed in the length direction A1 and the width direction A2, respectively. Referring to FIG. 23D, the protruding portion 701c has a rectangular parallelepiped shape, and the concave portion 701d has a concave shape closed in the length direction A1 and the width direction A2. Referring to FIGS. 23E and 23F, the protruding portion 701c has a rectangular parallelepiped shape, and the concave portion 701d has a concave shape that is closed in the length direction A1 but has a side open in the width direction A2. Referring to FIGS. 23G and 23H, the protruding portion 701c has an angular shape (cone or pyramid shape), and the concave portion 701d has a concave shape that is closed in the length direction A1 but has a side open in the width direction A2.

The magnetic force can be used to align the connecting members 701-1 and 701-2 in the radial direction by preventing the connecting members 701-1 and 701-2 from sliding in the length direction A1. FIG. 23I is a cross-sectional view of a slip prevention structure using magnetic force. Refer to Figure 23I, connecting parts 701 may include a first magnetic component 701e and a second magnetic component 701f located at the opposite side of the first magnetic component 701e. The first magnetic member 701e and the second magnetic member 701f have opposite polarities. When the position of the connecting member 701 in the circumferential direction is aligned in a straight line along the radial direction, the first magnetic member 701e of the connecting member 701-1 positioned outward in the radial direction is attracted to the connecting member 701-2 by magnetic force. The second magnetic member 701f positioned inward in the radial direction. Therefore, the connecting member 701-1 and the connecting member 701-2 can be aligned in the radial direction without deviating in the length direction A1 of the display 301. Therefore, the connection member 701 can be stably aligned in the radial direction. The first magnetic member 701e and the second magnetic member 701f may have a protruding shape and a recessed shape as illustrated in FIGS. 23A to 23H, respectively.

The friction force can be used to align the connecting members 701-1 and 701-2 in the radial direction by preventing the sliding of the connecting members 701-1 and 701-2 in the length direction A1. Fig. 23J is a cross-sectional view of a slip prevention structure using friction. Referring to FIG. 23J, the connecting member 701 may include a first facing portion 701h located at the side of the image display surface 301-1 and a second facing portion 701i located at the opposite side of the first facing portion 701h. At least one of the first facing portion 701h and the second facing portion 701i may include a friction portion 701j having an enhanced friction force. The friction portion 701j can be embodied by, for example, attaching a friction portion member made of an elastomer having a large friction force to the connection member 701, coating the connection member 701 with a material having a large friction force, or applying A certain surface roughness is applied to the connection member 701. When the position of the connecting member 701 in the circumferential direction is aligned in a straight line along the radial direction, the first facing portion 701h of the connecting member 701-1 positioned outward in the radial direction and the diameter of the connecting member 701-2 The second facing portion 701i positioned inward in the direction contacts. Since the friction part 701j is provided in the first facing part 701h and the second facing part 701i Therefore, the connecting member 701-1 and the connecting member 701-2 can be aligned in the radial direction by friction without deviating in the length direction A1 of the display 301. Therefore, the connection member 701 can be stably aligned in the radial direction.

Fig. 23K is a schematic plan view of a slip prevention structure using frictional force. Referring to FIG. 23K, the slippage preventing portion 701k is provided between the connecting members 701. The slip prevention portion 701k is provided on the rear surface 301-2 of the display 301. The slippage prevention portion 701k may have a strip shape. The slippage prevention portion 701k may be embodied by attaching a member having a strip shape made of, for example, an elastomer having a large friction force to the rear surface 301-2 of the display 301. The connecting part 701 may include a first facing portion 701h located at the side of the image display surface 301-1 and a second facing portion 701i located at the opposite side of the image display surface 301-1. When the position of the connecting member 701 in the circumferential direction is aligned in the radial direction, the first facing portion 701h of the connecting member 701-1 positioned outward in the radial direction and the connecting member 701-2 in the radial direction The second facing portion 701i positioned upward and inward contacts. Even when the first facing portion 701h slips about the second facing portion 701i to shift in the length direction A1, the first facing portion 701h still contacts the slip prevention portion 701k, and therefore the first facing portion 701h is not in the length direction A1 It slides upward and remains in contact with the second facing portion 701i. Therefore, the connection member 701 can be stably aligned in the radial direction. Although it is not illustrated, at least one of the first facing portion 701h and the second facing portion 701i may include the friction portion 701j of FIG. 23J.

The zipper lock structure can be used as a structure in which the connecting members 701-1 and 701-2 are aligned in the radial direction by preventing the connecting members 701-1 and 701-2 from sliding in the length direction A1. Fig. 23L is a schematic plan view of a slip prevention structure using a zipper lock structure. Referring to Figure 23L, the connecting part 701 may include a protruding portion 701m and The concave portion 701n. The protruding portion 701m may include an extending portion 701m-1 extending in the thickness direction of the display 301 (ie, in the radial direction of the rollers 103 and 203), and extending from the extending portion 701m-1 in the length direction A1 and extending in length An elastic arm 701m-2 that is elastically deformable in the direction A1. The recessed portion 701n may include a receiving portion 701n-1 recessed to receive the protruding portion 701m, and a capturing portion 701n-3 provided around the opening 701n-2 of the receiving portion 701n-1 to capture the elastic arm 701m-2. The width W2 of the opening 701n-2 is smaller than the width W1 of the elastic arm 701m-2.

When the position of the connecting member 701 in the circumferential direction is aligned in a straight line along the radial direction, the protruding portion 701m of the connecting member 701-1 positioned outward in the radial direction is coupled to the connecting member 701-2 in the radial direction. The concave portion 701n positioned inward in the direction. In other words, as the display 301 is wound around the rollers 103 and 203, the connecting member 701-1 approaches the connecting member 701-2, and then the elastic arm 701m-2 is inserted into the receiving portion 701n-1 through the opening 701n-2. Since the width W2 of the opening 701n-2 is smaller than the width W1 of the elastic arm 701m-2, the elastic arm 701m-2 is captured by the capturing portion 701n-3 provided at the edge of the opening 701n-2. In this state, the connecting member 701-1 is pushed by the elastic force applied to the display 301 toward the connecting portion 701-2, and thus the elastic arm 701m-2 is deformed in a direction in which the width W1 decreases. When the width W1 of the elastic arm 701m-2 is equal to the width W2 of the opening 701n-2, the elastic arm 701m-2 passes through the opening 701n-2 and is inserted into the receiving portion 701n-1. Then, the elastic arm 701m-2 returns to the original state, and is captured by the capturing portion 701n-3. Therefore, the protruding portion 701m is maintained in a state of being inserted into the concave portion 701n, and therefore the connection member 701 can be stably aligned in the radial direction.

When the display 301 expands outward from the rollers 103 and 203, a force (separation force) is applied to the connection in the direction in which the connection part 701-1 is separated from the connection part 701-2. Part 701-1. When a separating force is applied to the connecting member 701-1 in a state where the elastic arm 701m-2 is captured by the capturing portion 701-3, the elastic arm 701m-2 deforms in a direction in which the width W1 decreases. When the width W1 of the elastic arm 701m-2 is equal to the width W2 of the opening 701n-2, the elastic arm 701m-2 passes through the opening 701n-2 and is separated from the receiving portion 701n-1. Therefore, the protruding portion 701m is separated from the concave portion 701n, and thus the display 301 expands outward from the rollers 103 and 203, thereby expanding outward from the first bodies 101 and 201.

The first bodies 101 and 201 can be supported on the bracket 501 so as to be slidable in the length direction A1. FIG. 24 is a perspective view of a rotatable display device according to an embodiment of the present invention.

Referring to FIG. 24, the first bodies 101 and 201 are illustrated by omitting the outer casing forming the appearance thereof. The bracket 501 extends in the longitudinal direction A1. A pair of rails 502 and 503 are provided at the bracket 501. The rails 502 and 503 extend in the longitudinal direction A1. The first bodies 101 and 201 are connected to the rails 502 and 503, respectively. According to the above structure, the first bodies 101 and 201 can be supported on the bracket 501 so as to be slidable in the length direction A1.

In an embodiment of the present invention, the track 502 may include a pair of sliding rods 502a and 502b. The sliding rod 502a is supported on the sliding rod 502b so as to be slidable in the length direction A1. The sliding rod 502b is supported on the bracket 501 so as to be slidable in the length direction A1. The first body 101 is connected to the sliding rod 502a. According to the above structure, the slide bar 502b can slide with respect to the bracket 501 within the range of the length of the bracket 501, and the slide bar 502a can slide with the slide bar 502b beyond the range of the length of the bracket 501. Therefore, although the length of the bracket 501 in the length direction A1 is reduced, the sliding range of the first body 101 may extend beyond the range of the length of the bracket 501.

Similarly, the track 503 may include a pair of sliding rods 503a and 503b. The sliding rod 503a is supported on the sliding rod 503b so as to be slidable in the length direction A1. The sliding rod 503b is supported on the bracket 501 so as to be slidable in the length direction A1. The first body 201 is connected to the sliding rod 503a. According to the above structure, although the length of the bracket 501 in the longitudinal direction A1 is reduced, the sliding range of the first body 201 may extend beyond the range of the length of the bracket 501.

The display 301 can be expanded from the first bodies 101 and 201 by only a necessary length. The extended length of the display 301 (that is, the length of the display 301 expanded outward from the first body 101 and 201) can be adjusted in multiple steps. The extension length can be adjusted by locking the first body 101 and 201 with respect to the second body 401 at a plurality of separate parts. The rotatable display device may include a locking unit to lock the first bodies 101 and 201 at a plurality of separated positions with respect to the second body 401.

Fig. 25A is a front view of a locking unit according to an embodiment of the present invention.

Referring to FIG. 25A, the locking unit according to an embodiment of the present invention may include a blocking member 1400 for locking the first bodies 101 and 201 at a plurality of separated positions. The blocking member 1400 according to the present invention selectively allows the first support member 6-1 to move in the accommodation direction A1-1 in which the first support member 6-1 is accommodated in the first bodies 101 and 201. The blocking member 1400 has a blocking position indicated by a solid line to prevent the first support member 6-1 from moving in the accommodation direction A1-1, and a dashed line to allow the first support member 6-1 to move in the accommodation direction A1-1 Unblocked position. For example, the blocking member 1400 may be supported on the first bodies 101 and 201 so as to be pivotable between the blocking position and the non-blocking position. The elastic member 1410 applies elastic force to the blocking member 1400 in a direction to be pivotable in the blocking position. The blocking member 1400 may include a blocking portion 1401 for blocking the first supporting member 6-1 in the accommodating direction A1-1, and partly exposed from the first body 101 and 201 to allow the user to set the non-blocking position. As part of 1402. The blocking member 1400 is positioned adjacent to the sprocket 195. The interval is generated between the segment link 601-1 connected to the sprocket 195 and having a changed conveying direction and the segment link 601-2 located before the segment link 601-1. As indicated by the solid line in FIG. 25, since the blocking portion 1401 captures the rear end portion 601-2a of the segment link 601-2 (ie, the end portion of the segment link 601-2 in the accommodation direction A1-1) Therefore, the blocking member 1400 blocks the movement of the first supporting member 6-1 in the accommodation direction A1-1.

When the first body 101 and 201 are separated from the second body 401, that is, when the first support member 6-1 moves in the direction A1-2 in which the first support member 6-1 expands outward from the first body 101 and 201 , The segmented link 601-1 pushes the blocking portion 1401, so that the blocking member 1400 is switched to the non-blocking position. When the interference between the segment link 601-1 and the blocking portion 1401 ends, the blocking member 1400 is returned to the blocking position by the elastic force of the elastic member 1410. Next, the segment link 601-1 reaches the position of the segment link 601-2, the rear end portion 601-2a of the segment link 601-2 is captured by the blocking portion 1401, and the first support member 6-1 is in the receiving direction Movement on A1-1 was stopped. As the above procedure is repeated, the first body 101 and 201 are separated from the second body 401, and the display 301 expands outward from the first body 101 and 201. In this state, for the first bodies 101 and 201, in order to move in a direction approaching the second body 401, the first support member 6-1 moves in the accommodation direction A1-1. However, since the rear end portion 601-2a of the segment link 601-2 is captured by the blocking portion 1401 of the blocking member 1400 at the blocking position, the first support member 6-1 is prevented from moving in the accommodation direction A1-1. Therefore, the first body 101 and 201 may not move in the direction approaching the second body 401, and the extended length of the display 301 can be maintained. When the display 301 is accommodated in the first bodies 101 and 201, the blocking member 1400 is switched to the non-blocking position by pushing the operating portion 1402, and therefore the first bodies 101 and 201 can approach The second body 401.

According to the above structure, the extended length of the display 301 can be adjusted in units of the length of the segment link 601.

Although FIG. 25A illustrates a structure that selectively allows the first supporting member 6-1 to move in the accommodation direction A1-1 by using the blocking member 1400, the blocking member 1400 may be used to selectively allow the second supporting member 6-2 to move in the receiving direction A1-1. Move up in the receiving direction A1-1.

Fig. 25B is a front view of the locking unit according to the embodiment of the present invention.

Referring to FIG. 25B, the locking unit according to this embodiment of the present invention may include a blocking member 1420. The blocking member 1420 selectively allows the sprocket 195 to rotate in the accommodation direction A1-3 in which the first support member 6-1 is accommodated in the first bodies 101 and 201. A plurality of protruding steps 195 b arranged in the circumferential direction are provided on the sprocket 195. The blocking member 1420 may have a blocking position where the rotation of the sprocket 195 in the accommodation direction A1-3 indicated by a solid line is prevented due to the blocking member 1420 being captured by the protruding step 195b, and the sprocket 195 indicated by a broken line in the accommodation direction A1 -3 Unblocked position where rotation is allowed. For example, the blocking member 1420 may be supported on the first bodies 101 and 201 so as to be pivotable between the blocking position and the non-blocking position. The elastic member 1430 applies elastic force to the blocking member 1420 in a direction to pivot to the blocking position. The blocking member 1420 may be partially exposed outward from the first bodies 101 and 201, so that the user can switch the blocking member 1420 to the non-blocking position. Although it is not illustrated, the first bodies 101 and 201 may have an operating part connected to the blocking member 1420 to switch the blocking member 1420 to the non-blocking position.

When the first body 101 and 201 are separated from the second body 401, that is, when the sprocket 195 rotates in the direction A1-4 in which the first support member 6-1 spreads out from the first body 101 and 201, the protruding step 195b Push the blocking part 1421 to block Part 1420 switches to the unblocking position. When the interference between the protruding step 195b and the blocking portion 1421 ends, the blocking member 1420 is returned to the blocking position by the elastic force of the elastic member 1430, and thus the rotation of the sprocket 195 in the accommodation direction A1-3 stops. As the above procedure is repeated, the first body 101 and 201 are separated from the second body 401, and the display 301 expands outward from the first body 101 and 201. In this state, for the first bodies 101 and 201, in order to move in a direction approaching the second body 401, the sprocket 195 rotates in the accommodation direction A1-3. However, since the sprocket 195 is captured by the blocking portion 1421 of the blocking member 1420 at the blocking position, the sprocket 195 is prevented from rotating in the accommodation direction A1-3. Therefore, the first body 101 and 201 may not be able to move in the direction approaching the second body 401, and the extended length of the display 301 may be maintained. When the display 301 is accommodated in the first body 101 and 201, the blocking member 1420 is switched to the non-blocking position by manipulating the operating part, and therefore the first body 101 and 201 can approach the second body 401.

According to the above structure, the extended length of the display 301 can be adjusted in units of the arrangement interval of the protruding steps 195b.

Although FIG. 25B illustrates a structure in which the sprocket 195 is selectively allowed to rotate in the accommodation direction A1-3 by using the blocking member 1420, the blocking member 1420 can be used to allow the sprocket 196, 295, and 296 to rotate in the accommodation direction A1-3. .

FIG. 26 is a schematic plan view of a rotatable display device according to an embodiment of the present invention. In FIG. 26, the first body 101 is mainly explained.

Referring to FIG. 26, the first bodies 101 and 201 are provided with guide rollers 104 and 204, respectively. The guide rollers 104 and 204 guide the display 301 spread out from the rollers 103 and 203 to the opening portions 111 and 211 provided in the first bodies 101 and 201. When the guide rollers 104 and 204 do not exist, if most of the display 301 surrounds Winding around the rollers 103 and 203, the display 301 travels toward the opening portions 111 and 211 along the path B1. If the display 301 is minimally wound around the drums 103 and 203, the display 301 travels toward the opening portions 111 and 211 along the path B2. In other words, the traveling direction of the display 301 unfolded through the opening portions 111 and 211 is changed in accordance with the change in the amount of roll-up of the display 301 around the drums 103 and 203. When the guide rollers 104 and 204 are provided, the traveling direction of the display 301 between the rollers 103 and 203 and the guide rollers 104 and 204 changes according to the amount of roll of the display 301 around the rollers 103 and 203 as indicated by paths B3 and B4 The indication is changed, and the traveling direction of the display 301 between the guide rollers 104 and 204 and the opening portions 111 and 211 is constant as indicated by the path B. Therefore, the traveling direction of the display 301 spread out from the opening portions 111 and 211 can be maintained constant.

The first supporting member 6-1 and the second supporting member 6-2 can be synchronously expanded/rolled back into the first body 101 and 201. FIG. 27 is a rear view of the rotatable display device according to an embodiment of the present invention. In FIG. 27, the outer shells of the first bodies 101 and 201 are omitted.

Referring to FIG. 27, the first sprocket 195 and the second sprocket 196 may be connected to each other by a power connection device. The power connection device may include, for example, gears, belts, timing belts, metal wires, and the like. An example of the power connection device is described with reference to FIG. 27. The second sprocket 196 includes a gear 1501. The second sprocket 196 includes a pulley 1506. The pulley 1504b forming a pair with the pulley 1506 includes a gear 1504a. Gear 1501 and gear 1504a are connected to each other via gears 1502 and 1503. A belt (for example, a timing belt 1505) is wound around the pulley 1506 and the pulley 1504b. Therefore, the first sprocket 195 and the second sprocket 196 can be rotated synchronously. Similarly, as illustrated by the reference numbers in parentheses in FIG. 27, the first sprocket 295 and the second sprocket 296 provided in the second body 401 can be borrowed It rotates synchronously by being connected by a power connection device in the same way. Therefore, the first supporting member 6-1 and the second supporting member 6-2 can be simultaneously unfolded/rolled back into the first body 101 and 201.

As the first body 101 and 201 approach the second body 401, the rollers 103 and 203 roll up the display 301. To this end, the drums 103 and 203 rotate in the direction in which the display 301 is rolled up. In the following description, various embodiments of the present invention of the structure of the rotating drums 103 and 203 are described. FIG. 28 is an exploded perspective view of a structure that rotatably supports the rollers 103 and 203 in the first bodies 101 and 201 according to an embodiment of the present invention. FIG. 29 is a cross-sectional view taken along the line EE ′ of FIG. 28.

Referring to FIGS. 28 and 29, one end portion 103-1 and 203-1 of the rollers 103 and 203 are rotatably supported on the frames 150 and 250. The other end portions 103-2 and 203-2 of the rollers 103 and 203 are rotatably supported on the frames 150 and 250 via the tension applying portion 7.

As the display 301 expands/rolls back into the first bodies 101 and 201 from the first bodies 101 and 201, the tensile force applying part 7 can be supported on the first bodies 101 and 201 and is the same as the rollers 103 and 203 Can be rotated in the direction of the. The tensile force applying portion 7 may include a torsion spring 63 and a rotation support member 60, one end portion 63b of the torsion spring 63 is supported on the rotation support member, and the rotation support member 60 is rotatably supported on the frames 150 and 250. The rotation support member 60 may include a bushing member 61 rotatably supported on the frames 150 and 250 and a shaft member having a support shaft 62c to rotatably support the other end portions 103-2 and 203-2 of the rollers 103 and 203 62. The bushing member 61 is rotatably supported on the frames 150 and 250. The shaft member 62 rotates together with the bush member 61. To this end, the bush member 61 and the shaft member 62 are provided with a first coupling portion 61a having complementary shapes that are coupled to each other in the rotation direction. And the second coupling portion 62a. The support shaft 62c is inserted into the inner diameter portion 63a of the torsion spring 63. One end portion 63 b of the torsion spring 63 is fixed to the shaft member 62. For example, one end portion 63 b of the torsion spring 63 is inserted into a fixing hole 62 b formed in the shaft member 62. The rollers 103 and 203 are provided with cavity portions 103-3 and 203-3. The torsion spring 63 is inserted into the cavity portions 103-3 and 203-3 in a state of being inserted around the support shaft 62c. The capturing portions 103-4 and 203-4 for capturing the other end portion 63c of the torsion spring 63 are provided in the cavity portions 103-3 and 203-3.

According to the above structure, the rollers 103 and 203 can be embodied, one of the end portions 103-1 and 203-1 is rotatably supported on the frames 150 and 250, and the other end portions 103-2 and 203-2 can be pulled The application part 7 is rotatably supported on the frames 150 and 250. In this state, as illustrated in FIG. 29, the initial elastic force F1 in the direction of the winding rollers 103 and 203 can be applied to the display 301 by rotating the rotation support member 60 in the direction D1. The tensile force in the direction in which the display 301 expands flatly can be applied to the display 301 by the initial elastic force F1.

When the initial elastic force F1 is in the active state, when the rotation support member 60 is in a free state where the rotation of the rotation support member 60 is not restricted, the rotation support member 60 is moved in the direction opposite to the direction D1 by the initial elastic force F1 D2 rotates upward, and therefore the initial elastic force F1 can be released. Therefore, the rotation support member 60 needs to be locked so as not to rotate in a state where the initial elastic force F1 is applied to the display 301.

In a state where the initial elastic force F1 is applied to the display 301, the rotation support member 60 is connected to at least one of the first support member 6-1 and the second support member 6-2. In other words, the rotation support member 60 is connected to at least one of the first support member 6-1 and the second support member 6-2 and locked in a state where the initial elastic force F1 is applied to the display 301. When at least one of the first support member 6-1 and the second support member 6-2 moves When moving, the rotating support member 60 rotates accordingly. For example, the rotation support member 60 may be connected to the sprockets 195, 196, 295, and 296. Therefore, when the sprockets 195, 196, 295, and 296 do not rotate, the rotation support member 60 does not rotate to be locked. When the sprockets 195, 196, 295, and 296 rotate, the rotation support member 60 rotates.

FIG. 30 is a perspective view of the connection structure of the rotation support member 60 and the sprockets 195, 196, 295, and 296 according to an embodiment of the present invention. Referring to FIGS. 27, 28 and 30, the gear portion 61b is provided on the rotation support member 60 (for example, the bush member 61). The gear portion 61b is connected to the sprockets 195, 196, 295, and 296. For example, the gear portion 61b is connected to a gear 1501 provided on a sprocket 196 (296) via gears 1507 to 1510. Since the rotation direction of the drums 103 and 203 and the rotation support member 60 is perpendicular to the rotation direction of the sprocket 196 (296), one of the gears 1507 to 1510 has a structure capable of changing the rotation direction by 90°. For example, the gear 1510 may include a spur gear portion 1510a connected to the gear 1509, and a helical gear portion 1510b that rotates coaxially with the spur gear portion 1510a. The gear portion 61b is a helical gear meshed with the helical gear portion 1510b. According to the above structure, the rotation support member 60 rotates interlockingly with the rotation of the sprockets 195, 196, 295, and 296 in accordance with the movement of the first support member 6-1 and the second support member 6-2.

As illustrated in FIG. 29, when the gear portion 61b rotates the rotation support member 60 in the direction D1, the initial elastic force F1 in the direction of rolling up the display 301 is applied to the rollers 103 and 203 in a state where the gear portion 61b and the helical gear portion 1510b is engaged, and the rotation support member 60 can be maintained in the state. In this state, when the first body 101 and 201 approach the second body 401/separate from the second body and therefore the display 301 is unfolded/rolled back into the first body from the first body 101 and 201, The rollers 103 and 203 and the rotating support member 60 are in the direction of unfolding the display 301 or in the rolling The direction of the display 301 rotates.

FIG. 31 is a graph of the relationship between the expansion distance of the display 301, the rotation amount of the drums 103 and 203, and the rotation amount of the rotation support member 60. Referring to Fig. 31, when the extension distance is "0", the initial rotation amount of the rollers 103 and 203 is "d1". The initial rotation amount “d1” does not indicate a state in which the rollers 103 and 203 actually rotate, but indicates a relative rotation amount with respect to the rotation support member 60 applying the initial elastic force F1.

The rotation amount of the drum 103 and 203 and the expansion distance of the display 301 do not have a linear proportional relationship. This is because the outer diameter of each of the drums 103 and 203 including the display 301 changes according to the amount of winding of the display 301 around the drums 103 and 203. In other words, when the amount of winding of the display 301 around the drums 103 and 203 is relatively small, the amount of rotation of the drums 103 and 203 with respect to the same extension distance is greater than the amount of rotation of the display 301 when the amount of winding around the drums 103 and 203 is relatively large . Therefore, the relationship between the expansion distance and the rotation amount of the drums 103 and 203 has a curved shape in which the inclination angle gradually increases as the expansion distance increases, as indicated by the curve E1 in FIG. 31.

If the rotation support member 60 has a structure that does not rotate, the amount of rotation of the rollers 103 and 203 is "d2" in a state where the display 301 is fully expanded outward from the first bodies 101 and 201. The amount of elastic force F2 provided to the drums 103 and 203 by the torsion spring 63 is proportional to the amount of rotation d2. Therefore, in a state where the display 301 is fully expanded outward from the first bodies 101 and 201, a strong elastic force F2 is applied to the rollers 103 and 203. Therefore, as the extension distance of the display 301 increases, a large force is required to separate the first body 101 and 201 from the second body 401.

According to the embodiment of the present invention, as the display 301 expands/rolls back into the first bodies 101 and 201 from the first bodies 101 and 201, the rotating support part The piece 60 rotates together with the rollers 103 and 203. Since the expansion distance of the display 301 with respect to the first body 101 and 201 is the same as the movement amount of the first support member 6-1 and the second support member 6-2, the rotation amount d3 of the rotation support member 60 is the same as that of the display 301 with respect to the first body. The extension distances of 101 and 201 have a linear proportional relationship. Therefore, the relationship between the extension distance and the rotation amount of the rotation support member 60 has a linear shape having an inclination angle E2a as indicated by a straight line E2 in FIG. 31.

The amount of elastic force applied to the drums 103 and 203 by the torsion spring 63 is proportional to the difference between the rotation amount of the drums 103 and 203 and the rotation amount of the rotation support member 60. In other words, the amount of elastic force applied to the rollers 103 and 203 by the torsion spring 63 is proportional to the rotation amount d4 when the display 301 is fully expanded outward from the first bodies 101 and 201. Therefore, according to the present embodiment in which the rotating support member 60 rotates together with the rollers 103 and 203 of the present invention, the elastic force F2 ′ is smaller than the structure in which the rotating support member 60 does not rotate when the display 301 is fully expanded outward from the first body 101 and 201 The elasticity in F2. Therefore, the change in the amount of elastic force applied to the drums 103 and 203 (ie, the change in the amount of tensile force applied to the display 301) in the expansion program of the display 301 can be reduced, and thus is consumed in the expansion program of the display 301 The change in force can be reduced.

The inclination angle E2a of the straight line E2 can be adjusted by the connection ratio of the gear portion 61b and the sprocket 196. For example, the inclination angle E2a of the straight line E2 can be adjusted by making one or more of the gears 1507 to 1510 a reduction gear. By appropriately setting the gear ratio of the reduction gear, the minimum value d _min of the difference between the rotation amount of the drums 103 and 203 and the rotation amount of the rotation support member 60 is equal to or greater than that used when the display 301 is to be expanded or wound If necessary, the expansion distance of the display 301 is maintained flat and the minimum elasticity required by the rotating drums 103 and 203 is generated. The inclination angle E2a of the straight line E2 may be set to be the same as the inclination angle E3a of the straight line E3 connecting the initial rotation amount and the final rotation amount of the drums 103 and 203. Therefore, the amount of change in the elastic force applied to the drums 103 and 203 by the torsion spring 63 according to the expansion distance of the display 301 can be reduced.

Although the first body 101 and 201 are manually approached to the second body 401/separated from the second body 401 to unfold the display 301 from the first body 101 and 201/the display 301 is rolled back to the The structure in the first body 101 and 201 is described in the above-mentioned embodiment of the present invention, but the first body 101 and 201 are allowed to approach the second body 401/separated from the second body 401 and separated from the second body 401 by using a motor. A structure in which the main bodies 101 and 201 expand the display 301/roll the display 301 back into the first main bodies 101 and 201 is possible. In one example, the motor rotates the first sprockets 195, 295 and the second sprockets 196, 296 to move the first support member 6-1 and the second support member 6-2, so that the first body 101 and 201 approach the second The main body 401/ is separated from the second body 401, so that the display 301 is expanded from the first bodies 101 and 201/the display 301 is rolled back into the first bodies 101 and 201. Referring to FIGS. 27 and 30, the rotatable display device may include a motor 1500. The motor 1500 rotates the gear 1507. The gear 1507 is connected to the gear 1501 provided in the sprocket 196. According to the above structure, when the first sprockets 195, 295 and the second sprockets 196, 296 rotate in the unfolding direction by driving the motor 1500 in the forward direction, the first support member 6-1 and the second support member 6-1 6-2 expands outward from the first body 101 and 201. Then, as the first bodies 101 and 201 are separated from the second body 401, the display 301 expands outward from the first bodies 101 and 201 to expand between the first bodies 101 and 201.

In contrast, when the first sprockets 195, 295 and the second sprockets 196, 296 rotate in the receiving direction by driving the motor 1500 in the reverse direction, the first The supporting member 6-1 and the second supporting member 6-2 are rolled back into the first bodies 101 and 201. Then, the first bodies 101 and 201 approach the second body 401, and the display 301 can be accommodated in the first bodies 101 and 201.

In this procedure, the rotation support member 60 can rotate in proportion to the expansion distance of the display 301.

Each of the segment links 601 includes a rib 601c extending from the rear surface 301-2 of the display 301 above the edges 301a and 301b to the image display surface 301-1. The rib 601c covers the edges 301a and 301b of the display 301. In the expanded state of the display 301, the edges 301a and 301b may be damaged by external shocks. According to an embodiment of the present invention, the edges 301a and 301b are covered by the ribs 601c. Therefore, the possibility of damage to the edges 301a and 301b of the display 301 can be reduced.

According to the above structure, in a state where the first supporting member 6-1 and the second supporting member 6-2 are spread out from the first bodies 101 and 201 to the outside, due to the pivoting of the hinge shaft 653 in the opposite direction The rotation is constrained by the first supporting member 6-1 and the second supporting member 6-2, so the display 301 can be stably maintained in an expanded state. The first supporting member 6-1 and the second supporting member 6-2 are expanded/rolled back from the first bodies 101 and 201 to the structure in the first bodies 101 and 201, and the display 301 is from the first bodies 101 and 201 The structure expanded/rolled back into the first body 101 and 201 and the structure of the rotating drums 103 and 203 are the same as those described above.
