Further, the rotatable display device may be any device having a structure for accommodating the first bodies 101 and 201 of the display 301 and the second body 401 being close to each other or spaced apart from each other.

The structure of the display 301 is not particularly limited to the above structure, and any structure that is flexibly bent to be accommodated in the first bodies 101 and 201, for example, to be wound around the drum, may be employed. For example, the display 301 can be a liquid crystal display (LCD), a light-emitting diode (LED) display, an organic light-emitting diode (OLED) display, or an electrophoretic display. .

In the closed state, the display 301 is accommodated to be wound inside the first bodies 101 and 201, and is deployed outward from the first bodies 101 and 201 as the first bodies 101 and 201 are spaced apart from the second body 401.

8 to 10 are perspective views showing an example in which the display 301 is housed in the first bodies 101 and 201, wherein Fig. 8 illustrates an open state, Fig. 9 illustrates a partially open state, and Fig. 10 illustrates a closed state. In FIGS. 8 to 10, the first bodies 101 and 201 are such that their interiors are visibly visible from the outside by omitting portions of the outer casing.

Referring to Figures 8 to 10, rollers 103 and 203 are mounted to the first bodies 101 and 201, respectively. The rollers 103 and 203 extend in the width direction A2 of the display 301 and are supported at the first bodies 101 and 201 to be rotatable around the longitudinal direction axes 103a and 203a.

The display 301 is wound around the outer circumference of the rollers 103 and 203. In the closed state, as shown in FIG. 10, the display 301 is housed in the first bodies 101 and 201 in a state of being wound around the rollers 103 and 203.

When the first bodies 101 and 201 in the state of FIG. 10 are moved in the longitudinal direction A1 of the display 301 to be separated from the second body 401, a pulling force is applied to the display 301. Accordingly, the rollers 103 and 203 are rotated in the direction in which the display 301 is unfolded as indicated by the arrows 191 and 291 in FIG. 9, and thus the display 301 is flared outward from the first bodies 101 and 201 to pass over the second body 401 at the first The body 101 and 201 are extended. When the first bodies 101 and 201 reach the open state, as illustrated in FIG. 8, the display 301 is in a state of being expanded at its maximum value.

In the open state, when the first bodies 101 and 201 approach the second body 401, the rollers 103 and 203 rotate in the direction in which the display 301 is rolled up. As illustrated in FIG. 10, the display 301 is wound around the drums 103 and 203 and housed in the first bodies 101 and 201. An elastic member (not shown) such as a torsion spring can apply an elastic force to the rollers 103 and 203 to wind the display 301 around the rollers 103 and 203. The structure in which the rollers 103 and 203 are rolled up to the display 301 is not particularly limited. An example of the structure in which the rollers 103 and 203 are rolled up to the display 301 is presented with reference to FIGS. 28 to 30.

The display 301 that is deployed outward from the first bodies 101 and 201 needs to be maintained in a flat state. When an external force is applied to the display 301 in an expanded state in a direction perpendicular to the image display surface 301-1, the display 301 is not maintained in a flat expanded state, so that an image displayed on the display 301 can be distorted.

Referring to FIGS. 1 through 7, the rotatable display device includes a support unit 6 for supporting the display 301 to be flat. The support unit 6 can be housed in the first bodies 101 and 201, for example, in a closed state, and can be flared from the first bodies 101 and 201 in an open state to support the display 301. The support 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.

Figure 13 is a front elevational view of the rotatable display device of Figure 11 in an open state. Figure 14 is a front elevational view of the rotatable display device of Figure 11 in a closed state. In FIGS. 11 to 14, the first bodies 101 and 201 are represented as being internally visible from the outside by omitting a partial outer casing.

Referring to FIGS. 11-14, the support unit 6 may include a first support member 6-1 and a second support 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 segment links 601 pivotally connected to each other. The first support member 6-1 may include a pair of first chains 603 and 623 housed in the first bodies 101 and 201. The second support member 6-2 may include a pair of second chains 605 and 625 housed 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 a chain having segmented links 601 that are pivotally coupled to each other. Among the first links 603 and 623 and the segment links 601 of 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 at a central portion of each of the first support member 6-1 and the second support member 6-2 A plurality of segmented links (eg, segmented links 603a and 605a or 623a and 625a) are secured to a single chain of the second body 401. Embodiments of the first support member 6-1 and the second support member 6-2 of the present invention are described below with reference to FIGS. 16 and 17.

The first and second housing units for accommodating the first support member 6-1 and the second support member 6-2 are respectively disposed at the first bodies 101 and 201. For example, the first housing unit 151 and the second housing unit 152 for accommodating the first chain 603 and the second chain 605 are disposed at the first body 101. The first housing unit 151 and the second housing unit 152 may be in the form of, for example, a groove extending in the width direction A2 of the display 301. The first housing unit 151 and the second housing unit 152 are positioned apart from each other in the longitudinal direction A1. Similarly, the first housing unit 251 and the second housing unit 252 for accommodating the first chain 623 and the second chain 625 are disposed at the first body 201. The first housing unit 251 and the second housing unit 252 may be in the form of, for example, a groove extending in the width direction A2 of the display 301. The second housing units 251 and 252 can be positioned apart from each other in the longitudinal direction A1.

The first sprocket and the second sprocket for transferring the first support member 6-1 and the second support member 6-2 into and out of the first bodies 101 and 201 may be disposed in the first bodies 101 and 201. The first sprocket and the second sprocket are positioned adjacent to the edges 301a and 301b 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 disposed at the first body 101. The first chain 603 and the second chain 605 are transported by the first sprocket 195 and the second sprocket 196 in the width direction A2 inside the first body 101 and outside the first body 101 in the longitudinal direction A1. 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 be rotatable about rotation axes 195a and 196a perpendicular to the image display surface 301-1. In other words, the rotation axes 195a and 196a are perpendicular to the longitudinal direction A1 and the width direction A2. The first sprocket 195 and the second sprocket 196 are disposed apart from each other in the longitudinal direction A1 by an interval 187 to correspond to the first housing unit 151 and the second housing unit 152, respectively. 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 longitudinal direction A1. Since the first chain 603 and the second chain 605 do not interfere with each other, the length of 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 disposed in the first body 201. The first chain 623 and the second chain 625 are conveyed inside the first body 201 in the width direction A2 and outside the first body 201 in the longitudinal direction A1 by the first sprocket 295 and the second sprocket 296. 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 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 longitudinal direction A1 and the width direction A2. The first sprocket 295 and the second sprocket 296 are disposed apart from each other in the longitudinal direction A1 by an interval 287 to correspond to the first housing unit 251 and the second housing unit 252, respectively. Therefore, the first chain 623 and the second chain 625 can be accommodated in the first body 201 to be offset from each other in the longitudinal direction A1. Since the first chain 623 and the second chain 625 do not interfere with each other, the length of 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 can have, for example, a polygonal shape. The length of one side of the polygon can be determined in consideration of the length of each of the segment links 601. For example, the length of one side of the polygon can be determined in consideration of the spacing between the hinge axes 653 of FIG. 16 of two adjacent segment links 601. In the present invention, although the sprocket 195, 196, 295, and 296 having a rectangular shape are used, the present invention is not limited thereto.

In the closed state, the first support member 6-1 and the second support member 6-2 are housed in the first housing unit 151 and the second housing unit 152 disposed in the first bodies 101 and 102 of FIG. 14 and the first The housing unit 251 and the second housing unit 252 are included. In this state, when the first body 101 and 201 are separated from the second body 401, the first support member 6-1 and the second support member 6-2 are deployed outward from the first body 101 and 201 to be in the first body. The extension between 101 and 201 and the second body 401. FIG. 15 illustrates a procedure in which the first support member 6-1 and the second support member 6-2 are deployed outward 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 longitudinal direction A1, the tensile force is applied to the first support member 6-1 and the second support member 6-2 in the longitudinal direction A1. This is because the guide links 603a, 605a, 623a, and 625a are connected to the second body 401. Next, the first support member 6-1 and the second support member 6-2 are deployed outward from the first bodies 101 and 201. As the first support member 6-1 and the second support member 6-2 are deployed outward from the first bodies 101 and 201, the sprocket wheels 195, 196, 295 and 296 are at the first support member 6-1 and the second support member. Rotation in the direction of 6-2 deployment, as illustrated in operations 1212, 1213, and 1214 of FIG. 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 bodies 101 and 201 is changed by the sprockets 195, 196, 295, and 296 to the length direction A1 from the first The bodies 101 and 201 are flared outward as illustrated in FIG. Therefore, the first bodies 101 and 201 can be separated from the second body 401. When the open state is reached, as illustrated in FIG. 13, the first support member 6-1 and the second support member 6-2 are expanded in the length direction A1 to support the expansion of the display 301 between the first bodies 101 and 201, respectively. Edges 301a and 301b.

The first support member 6-1 and the second support member 6-2 are in the form of a chain having segmented links 601 that are pivotally coupled to each other but whose pivot angle is limited. In other words, although the segment link 601 is not prevented from pivoting in one direction to wrap around the sprocket wheels 195, 196, 295, and 296, the segment link 601 is no longer pivoted in the deployed state.

16 and 17 are front views of the first support member 6-1 and the second support 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 coupled to each other to be pivotable about a hinge axis 653. The hinge shaft 653 is an axis perpendicular to the image display surface 301-1. In other words, the hinge shaft 653 is an axis perpendicular to the longitudinal direction A1 and the width direction A2. Therefore, the first support member 6-1 is a chain that is bendable on a plane including the display 301. The segmented links 601 are coupled to each other to be pivotable between an expanded state and a curved state in one direction. The pivoting of the first support member 6-1 in the expansion direction 658 is constrained. To this end, a stopper 601a for restraining the pivoting of the first support member 6-1 is provided in the segment link 601. When the segment link 601 expands, the adjacent stops 601a contact each other such that the pivoting of the first support member 6-1 in the expansion direction 658 is constrained. Thus, as illustrated in FIG. 1, the edge 301a of the display 301 that is flared from the first bodies 101 and 201 can be supported by the first support member 6-1. The center 655 of the hinge shaft 653 is displaced from the center 654 of the segmentation link 601 by a spacing 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 constrained so that the first support member 6-1 can be stably maintained in the expansion status.

Referring to Fig. 17, the second support member 6-2 is in the form of a chain in which adjacent segment links 601 are coupled to each other to be pivotable about a hinge axis 653 perpendicular to the image display surface 301-1. Therefore, the second support member 6-2 is a chain that is bendable on a plane including the display 301. The segment links 601 are coupled to each other to be pivotable between a straightened state and a curved state in one direction. The pivoting of the second support member 6-2 in the expansion direction 657 is constrained. 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 is expanded, the adjacent stoppers 601a are in contact with each other such that the pivoting of the second support member 6-2 in the expansion direction 657 is restricted. Thus, as illustrated in FIG. 1, the edge 302a of the display 301 that is flared from the first bodies 101 and 201 can be supported by the second support member 6-2. The center 655 of the hinge shaft 653 is displaced from the center 654 of the segmentation link 601 by a spacing 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 restrained, so that the second support member 6-2 can be stably maintained in the expansion status.

In the open state of FIG. 13, when the first bodies 101 and 201 approach the second body 401, a compressive force in the longitudinal direction A1 is applied to the first support member 6-1 and the second support member 6-2. Next, the first support member 6-1 and the second support member 6-2 are pushed toward the first bodies 101 and 201. The sprocket wheels 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. Rotate in the direction of 201 and 201. The conveying direction of the first supporting member 6-1 and the second supporting member 6-2 is changed from the longitudinal direction A1 to the width direction A2 by the sprocket wheels 195, 196, 295 and 296, and thus the first supporting member 6-1 and the second The support member 6-2 is housed in the housing units 151, 152, 251, and 252. When the closed state is reached, as illustrated in FIG. 14, the first support member 6-1 and the second support member 6-2 are completely housed in the first bodies 101 and 201. As described above, the display 301 is housed in the first bodies 101 and 201 by being wound around the rollers 103 and 203.

According to the above configuration, the edges 301a and 301b of the display 301 that are flared from the first bodies 101 and 201 are supported by the first support member 6-1 and the second support member 6-2, and thus the display 301 can be flatly maintained. 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 thus the first bodies 101 and 201 can be enlarged. According to the embodiment of the present invention, since the first support member 6-1 and the second support 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 with each other. The structure in which the support member is wound around the drum together with the display can be reduced.

Further, with respect to the structure in which the support member is wound around the drum together with the display, the pivot axis of the segment link forming the support member is the width direction of the display. The support member having the above structure is extremely weak under an external force in a direction perpendicular to the image display surface of the display. According to an 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 are strongly resistant to an 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 link 601 of the first support member 6-1 and the second support member 6-2 are opposite to each other. Therefore, the first support member 6 is in a state where the first support member 6-1 and the second support member 6-2 are deployed outward from the first bodies 101 and 201 due to the pivoting about the hinge shaft 653 in the opposite direction. 1 and the second support member 6-2 are restrained, so that the display 301 can be stably maintained in an open state.

Figure 18 is a plan view of the rotatable display device of Figure 11 in an open state. Referring to Fig. 18, in order to flatly hold the display 301, 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 flatly maintained. To this end, a connection structure that connects the display 301 with the support unit 6 to prevent the display 301 from being lifted from the support unit 6 can be used in the rotatable display device.

Figure 19 is an exploded perspective view of a connection structure in accordance with an embodiment of the present invention. Figure 20 is a rear perspective view of the joint structure of Figure 19. 21 is a cross-sectional view taken along line C-C' of FIG. 20. 22A and 22B are conceptual views for explaining a procedure in which the connecting member and the supporting unit 6 are connected to each other. FIG. 23A is a perspective view illustrating a state in which 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 and the first support member 6-1 and the display 301 The connection structure is the same. Therefore, in FIGS. 19 to 23A, reference numerals for describing the connection structure between the second support member 6-2 and the display 301 are indicated in parentheses.

Referring to FIGS. 19-23A, a plurality of connecting members 701 are coupled to the edges 301a and 301b of the display 301. Connection member 701 can be, for example, a clip type. The spacing of the connecting members 701 disposed 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 members 701 can be the same as the spacing between the segmented links 601. In another example, the spacing of the connecting members 701 may increase as it approaches the second body 401 and may decrease as it approaches the rollers 103 and 203. The length of the display 301 wound around the rollers 103 and 203 once the display 301 is wound around the rollers 103 and 203 for a plurality of times is greater than the number of times the display 301 surrounds the rollers 103 and 203 once the display 301 is relatively small around the rollers 103 and 203. length. In view of the above, the pitch of the connecting member 701 can be determined such that when the display 301 is wound around the rollers 103 and 203, the connecting member 701 can be aligned in a 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 positions of the connecting members 701 in the circumferential direction are aligned in a radial direction. According to the above configuration, when the display 301 is wound around the rollers 103 and 203, the image display surface 301-1 and the rear surface 301-2 are spaced apart from each other by a certain interval. Therefore, when the display 301 is wound around the drums 103 and 203 or flared outward from the rollers 103 and 203, the image display surface 301-1 is damaged due to 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 radial direction, the protruding portion 701c of the connecting member 701-1 which is outwardly positioned 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 disposed in the radial direction without the deviation in the longitudinal direction A1 of the display 301. Therefore, the connecting member 701 can be stably aligned in the radial direction.

Referring to Fig. 21, each of the connecting members 701 may include a fixed portion 701a to which the edge 301a or 301b of the display 301 is fixed and a first connecting portion 701b stepped from the fixed portion 701a. The first connection portion 701b is coupled to the second connection portion 601b, which is disposed at each of the segment links 601 that form the first support member 6-1 and the second support member 6-2. For example, the first connection portion 701b has a protruding shape, and the second connection portion 601b has a shape of an insertion groove into which the first connection portion 701b is inserted, or vice versa. The insertion groove may have a shape that is cut in the longitudinal direction A1. Even when the pitch of the connecting portion 701 is not constant, the first connecting portion 701b can be easily coupled to the second connecting portion 601b. According to the above configuration, 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, Thereby it is maintained flat.

22A is a schematic plan view of FIG. 20, showing the rollers 103 and 203 and the first support member 6-1 and the second support member 6-2 in the directions along the rotational axes 103a and 203a of the rollers 103 and 203. View 1001. 22B is a schematic rear view of FIG. 20, showing the drums 103 and 203 and the first support member 6-1 and the second support member 6-2 along the axis of rotation of the sprocket wheels 195, 196, 295, and 296. View 1003 viewed in the direction of 195a, 196a, 295a, and 296a. Referring to Figures 20-22B, the connecting member 701 and the segment link 601 are coupled to each other until the display 301 is deployed outwardly from the rollers 103 and 203.

As described above, the axes of rotation 195a, 196a, 295a, and 296a of the sprockets 195, 196, 295, and 296 are perpendicular to the axes of rotation 103a and 203a of the rollers 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 moving directions of the first support member 6-1 and the second support member 6-2 are The sprockets 195, 196, 295, and 296 are changed to the longitudinal direction A1. Therefore, the segmentation link 601 at the sprockets 195, 196, 295, and 296 has been 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 a helical gear to connect the display 301 and the first support member 6-1 and the second support member 6-2 to each other.

In FIGS. 22A and 22B, when the first bodies 101 and 201 are moved away from the second body 401, the display 301 is expanded outward from the rollers 103 and 203 and moved in the longitudinal 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 moving directions of the first support member 6-1 and the second support member 6-2 are sprocket 195, 196, 295 and 296 are changed to the length direction A1. During the change of the moving direction, that is, during the rotation of the segment link 601 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 are gradually reduced as indicated. Likewise, the spacing between the edges 301a and 301b of the display 301 and the segmentation links 601 is gradually reduced as indicated by arrows 1021, 1022, and 1023 as illustrated by view 1003 of Figure 22B. Although the segment link 601 connected to the first sprocket 195, 295 and the second sprocket 196 and 296 approaches the display 301 by changing its moving direction, as illustrated in FIGS. 20 and 21, the connecting member 701 is The first connecting portion 701b is sequentially coupled to the second connecting portion 601b of each segment connecting rod sequence 601, and the display 301 and the segment connecting link 601 are outwardly deployed from the first bodies 101 and 201. According to the above configuration, the display 301 can be stably supported without being separated from the first support member 6-1 and the second support member 6-2, and thus the display 301 extending outward from the first bodies 101 and 201 can be Keep it flat.

When the first body 101 and the second body 201 approach the second body 401, the segment links 601 connected to the sprockets 195, 196, 295, and 296 change the moving direction from the length direction A1 to the width direction A2. In the program, the segment link 601 is gradually separated from the edges 301a and 301b of the display 301, and the first connection portion 701b is separated from the second connection portion 601b. The display 301 is housed 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 housed in the housing 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 a structure to prevent the respective directions in the radial direction The connecting members 701-1 and 701-2 positioned outward and inward are slid in the longitudinal direction A1 to align the connecting members 701-1 and 701-2. However, the shape of the protruding portion 701c and the concave portion 701d is not limited to the shape illustrated in Fig. 23A. 23B to 23H illustrate various shapes of the protruding portion 701c and the concave 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 which are closed in the longitudinal 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 (conical or pyramidal shape) and a concave shape which are closed in the longitudinal 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 longitudinal 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 longitudinal 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 (conical or pyramidal shape), and the concave portion 701d has a concave shape that is closed in the longitudinal 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 sliding of the connecting members 701-1 and 701-2 in the longitudinal direction A1. Figure 23I is a cross-sectional view of a slip prevention structure using a magnetic force. Referring to FIG. 23I, the connecting member 701 may include a first magnetic member 701e and a second magnetic member 701f located at an opposite side of the first magnetic member 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 the radial direction, the first magnetic member 701e of the connecting member 701-1 positioned outward in the radial direction is magnetically attracted to the connecting member 701-2 The second magnetic member 701f is 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 being deviated in the longitudinal direction A1 of the display 301. Therefore, the connecting 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 concave shape as illustrated in FIGS. 23A to 23H, respectively.

The frictional 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 longitudinal direction A1. 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 at a side of the image display surface 301-1 and a second facing portion 701i at an 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 frictional force. The friction portion 701j can be embodied, for example, by attaching a friction portion member made of an elastic body having a large frictional force to the joint member 701, coating the joint member 701 with a material having a large friction force, or A certain surface roughness is applied to the connecting member 701. 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 which is outwardly positioned in the radial direction and the diameter of the connecting member 701-2 The second facing portion 701i positioned inward in the direction is in contact. Since the friction portion 701j is disposed at at least one of the first facing portion 701h and the second facing portion 701i, the connecting member 701-1 and the connecting member 701-2 can be aligned in the radial direction by friction without The display 301 is offset in the longitudinal direction A1. Therefore, the connecting member 701 can be stably aligned in the radial direction.

Fig. 23K is a schematic plan view of a slip preventing structure using friction. Referring to Fig. 23K, the slip preventing portion 701k is disposed between the connecting members 701. The slip preventing portion 701k is disposed on the rear surface 301-2 of the display 301. The slip preventing portion 701k may have a strip shape. The slip preventing portion 701k can be embodied by attaching a strip-shaped member made of, for example, an elastic body having a large friction force to the rear surface 301-2 of the display 301. The connecting member 701 may include a first facing portion 701h at a side of the image display surface 301-1 and a second facing portion 701i at an 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 in which the connecting member 701-1 is outwardly positioned in the radial direction and the connecting member 701-2 are in the radial direction. The second inwardly positioned second facing portion 701i is in contact. Even when the first facing portion 701h is slid with respect to the second facing portion 701i to be displaced in the longitudinal direction A1, the first facing portion 701h still contacts the slip preventing portion 701k, and thus the first facing portion 701h is not in the length direction A1 It is slid upward and is maintained in a state of contacting the second facing portion 701i. Therefore, the connecting member 701 can be stably aligned in the radial direction. Although 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 sliding of the connecting members 701-1 and 701-2 in the longitudinal direction A1. Figure 23L is a schematic plan view of a slip prevention structure using a zipper locking structure. Referring to FIG. 23L, the connecting member 701 may include a protruding portion 701m and a concave portion 701n. The protruding portion 701m may include an extending portion 701m-1 extending in the thickness direction of the display 301 (i.e., in the radial direction of the rollers 103 and 203), and extending from the extending portion 701m-1 in the length direction A1 and at the length The elastic arm 701m-2 elastically deformable in the direction A1. The concave portion 701n may include a accommodating portion 701n-1 recessed to accommodate the protruding portion 701m, and a catch portion 701n-3 disposed around the opening 701n-2 of the accommodating 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 the radial direction, the protruding portion 701m of the connecting member 701-1 that is outwardly positioned in the radial direction is coupled to the diameter of the connecting member 701-2. A 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 accommodating portion 701n-1 via 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 the direction in which the width W1 is decreased. 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 accommodating 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 thus the connecting member 701 can be stably aligned in the radial direction.

When the display 301 is deployed outward from the rollers 103 and 203, a force (separation force) is applied to the connecting member 701-1 in a direction in which the connecting member 701-1 is separated from the connecting member 701-2. When the separation 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 is deformed in a direction in which the width W1 is decreased. 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 accommodating portion 701n-1. Therefore, the protruding portion 701m is separated from the concave portion 701n, and thus the display 301 is flared outward from the rollers 103 and 203, thereby expanding outward from the first bodies 101 and 201.

The first bodies 101 and 201 may be supported on the bracket 501 to be slidable in the longitudinal direction A1. Figure 24 is a perspective view of a rotatable display device in accordance with an embodiment of the present invention.

Referring to Fig. 24, the first bodies 101 and 201 are explained 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 disposed 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 tracks 502 and 503, respectively. According to the above structure, the first bodies 101 and 201 can be supported on the bracket 501 to be slidable in the longitudinal direction A1.

In an embodiment of the invention, the track 502 can include a pair of slide bars 502a and 502b. The slide bar 502a is supported on the slide bar 502b to be slidable in the longitudinal direction A1. The slide bar 502b is supported on the bracket 501 to be slidable in the longitudinal direction A1. The first body 101 is coupled to the slider 502a. According to the above configuration, 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 respect to the slide bar 502b beyond the length of the bracket 501. Therefore, although the length of the bracket 501 in the longitudinal direction A1 is reduced, the sliding range of the first body 101 can extend beyond the length of the bracket 501.

Likewise, track 503 can include a pair of sliders 503a and 503b. The slide bar 503a is supported on the slide bar 503b to be slidable in the longitudinal direction A1. The slide bar 503b is supported on the bracket 501 to be slidable in the longitudinal direction A1. The first body 201 is coupled to the slide bar 503a. According to the above configuration, although the length of the bracket 501 in the longitudinal direction A1 is reduced, the sliding range of the first body 201 can extend beyond the length of the bracket 501.

The display 301 can be flared outwardly from the first bodies 101 and 201 by only the necessary length. The extended length of the display 301 (i.e., the length of the display 301 that is flared outward from the first bodies 101 and 201) can be adjusted in a plurality of steps. The extended length can be adjusted by locking the first bodies 101 and 201 with respect to the second body 401 at a plurality of separate portions. The rotatable display device can include a locking unit to lock the first bodies 101 and 201 at a plurality of discrete positions with respect to the second body 401.

Figure 25A is a front elevational view of a locking unit in accordance with an embodiment of the present invention.

Referring to Figure 25A, a locking unit in accordance with an embodiment of the present invention can include a blocking member 1400 for locking the first bodies 101 and 201 at a plurality of discrete locations. The blocking member 1400 according to the present invention selectively allows the first supporting member 6-1 to move in the accommodating direction A1-1 in which the first supporting 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 that prevents the first supporting member 6-1 from moving in the accommodating direction A1-1, and a position indicated by a broken line allows the first supporting member 6-1 to move in the accommodating direction A1-1 Non-blocking position. For example, the blocking member 1400 can be supported on the first bodies 101 and 201 to be pivotable between a blocking position and a non-blocking position. The resilient member 1410 applies an elastic force to the blocking member 1400 in one 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 receiving direction A1-1, and an operating portion exposed to the outer portion from the first body 101 and 201 for the user to set the non-blocking position. 1402. The blocking member 1400 is positioned adjacent to the sprocket 195. The spacing is created between the segmented link 601-1 that is coupled to the sprocket 195 and has a varying direction of transport and the segmented link 601-2 that precedes the segmented 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 (i.e., the end portion of the segment link 601-2 in the accommodating direction A1-1) Therefore, the blocking member 1400 blocks the movement of the first supporting member 6-1 in the accommodating direction A1-1.

When the first bodies 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 members 6-1 are expanded outward from the first bodies 101 and 201, The segment link 601-1 pushes the blocking portion 1401 such 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, and 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 accommodating direction. The movement on A1-1 is stopped. As the above procedure is repeated, the first bodies 101 and 201 are separated from the second body 401, and the display 301 is expanded outward from the first bodies 101 and 201 to expand outward. In this state, for the first bodies 101 and 201, the first support member 6-1 moves in the accommodating direction A1-1 in order to move in the direction approaching the second body 401. 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 supporting member 6-1 is prevented from moving in the accommodating direction A1-1. Therefore, the first bodies 101 and 201 may not move in a direction approaching the second body 401, and the extended length of the display 301 may be maintained. When the display 301 is housed 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 thus the first bodies 101 and 201 can approach the second body 401.

According to the above configuration, 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 support member 6-1 to move in the accommodating direction A1-1 by using the blocking member 1400, the blocking member 1400 can be used to selectively allow the second supporting member 6-2 to Move in the accommodation direction A1-1.

Figure 25B is a front elevational view of a locking unit in accordance with an embodiment of the present invention.

Referring to FIG. 25B, the locking unit according to the present embodiment of the present invention may include a blocking member 1420. The blocking member 1420 selectively allows the sprocket 195 to rotate in the accommodating direction A1-3 in which the first supporting member 6-1 is accommodated in the first bodies 101 and 201. A plurality of protruding steps 195b arranged in the circumferential direction are provided on the sprocket 195. The blocking member 1420 may have a blocking position in which the rotation of the sprocket 195 indicated by the solid line in the accommodating direction A1-3 is prevented due to the blocking member 1420 being caught by the protruding step 195b, and the sprocket 195 indicated by the broken line in the accommodating direction A1 The rotation on -3 is allowed for the non-blocking position. For example, the blocking member 1420 can be supported on the first bodies 101 and 201 to be pivotable between a blocking position and a non-blocking position. The resilient member 1430 applies an elastic force to the blocking member 1420 in one direction to pivot to the blocking position. The blocking member 1420 can be partially exposed outwardly from the first bodies 101 and 201 such that the user can switch the blocking member 1420 to the non-blocking position. Although not illustrated, the first bodies 101 and 201 may be provided with an operating portion that is coupled to the blocking member 1420 to switch the blocking member 1420 to the non-blocking position.

When the first bodies 101 and 201 are separated from the second body 401, that is, the sprocket 195 is rotated in the direction A1-4 in which the first support member 6-1 is expanded outward from the first bodies 101 and 201, the protruding step 195b The blocking portion 1421 is pushed such that the blocking member 1420 is switched to the non-blocking 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 accommodating direction A1-3 is stopped. As the above procedure is repeated, the first bodies 101 and 201 are separated from the second body 401, and the display 301 is expanded outward from the first bodies 101 and 201 to expand outward. In this state, for the first bodies 101 and 201, the sprocket 195 is rotated in the accommodating direction A1-3 in order to move in the direction approaching the second body 401. However, since the sprocket 195 is caught by the blocking portion 1421 of the blocking member 1420 at the blocking position, the sprocket 195 is prevented from rotating in the accommodating direction A1-3. Therefore, the first bodies 101 and 201 may not move in a direction approaching the second body 401, and the extended length of the display 301 may be maintained. When the display 301 is housed in the first bodies 101 and 201, the blocking member 1420 is switched to the non-blocking position by manipulating the operating portion, and thus the first bodies 101 and 201 can approach the second body 401.

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

Although FIG. 25B illustrates a structure that selectively allows the sprocket 195 to rotate in the accommodating 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 accommodating direction A1-3. .

Figure 26 is a schematic plan view of a rotatable display device in accordance with an embodiment of the present invention. In Fig. 26, the first body 101 is mainly explained.

Referring to Fig. 26, first bodies 101 and 201 are provided with guide rollers 104 and 204, respectively. The guide rollers 104 and 204 guide the display 301 which is unfolded 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 are not present, if the display 301 is mostly wound around the rollers 103 and 203, the display 301 travels along the path B1 toward the opening portions 111 and 211. If the display 301 is wound around the rollers 103 and 203 at a minimum, the display 301 travels along the path B2 toward the opening portions 111 and 211. In other words, the traveling direction of the display 301 developed through the opening portions 111 and 211 is changed in accordance with the change in the amount of winding of the display 301 around the rollers 103 and 203. When the guide rollers 104 and 204 are provided, the direction of travel of the display 301 between the rollers 103 and 203 and the guide rollers 104 and 204 is changed according to the amount of winding of the display 301 around the rollers 103 and 203 as by paths B3 and B4. The indication changes, the direction of travel 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 which is flared outward from the opening portions 111 and 211 can be maintained constant.

The first support member 6-1 and the second support member 6-2 can be simultaneously unfolded/rolled back into the first body from the first bodies 101 and 201. Figure 27 is a rear elevational view of a rotatable display device in accordance with an embodiment of the present invention. In Fig. 27, the outer casings of the first bodies 101 and 201 are omitted.

Referring to Figure 27, the first sprocket 195 and the second sprocket 196 can be coupled to each other by a power connection. The power connection device may include, for example, a gear, a belt, a timing belt, a wire, or the like. An example of a power connection device is described with reference to FIG. The second sprocket 196 is provided with a gear 1501. The second sprocket 196 is provided with a pulley 1506. A pulley 1504b that forms a pair with the pulley 1506 is provided with a gear 1504a. Gear 1501 and gear 1504a are coupled to each other via gears 1502 and 1503. A belt (eg, timing belt 1505) is wrapped around pulley 1506 and pulley 1504b. Therefore, the first sprocket 195 and the second sprocket 196 can be rotated in synchronization. Also, as illustrated by the reference numerals in parentheses in Fig. 27, the first sprocket 295 and the second sprocket 296 provided in the second body 201 can be synchronously rotated by being connected by the power connecting means in the same manner. Therefore, the first support member 6-1 and the second support member 6-2 can be simultaneously unfolded/rolled back from the first bodies 101 and 201 into the first body.

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

Referring to Figures 28 and 29, one end portions 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 202-3 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 is unfolded/rolled back from the first bodies 101 and 201 into the first bodies 101 and 201, the tension applying portion 7 can be supported on the first bodies 101 and 201 and is the same as the rollers 103 and 203. The direction can be rotated. The tension applying portion 7 may include a torsion spring 63 and a rotation supporting member 60 on which one end portion 63b of the torsion spring 63 is supported, and the rotation supporting member 60 is rotatably supported on the frames 150 and 250. The rotary support member 60 may include a bush 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 202-3 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 bushing member 61. To this end, the bushing member 61 and the shaft member 62 are provided with a first coupling portion 61a and a second coupling portion 62a having complementary shapes and coupled to each other in the rotational direction. The support shaft 62c is inserted into the inner diameter portion 63a of the torsion spring 63. One end portion 63b of the torsion spring 63 is fixed to the shaft member 62. For example, one end portion 63b of the torsion spring 63 is inserted into the fixing hole 62b formed in the shaft member 62. The rollers 103 and 203 are provided with cavity portions 103-3 and 203-5. The torsion spring 63 is inserted into the cavity portions 103-1 and 203-1 in a state of being inserted around the support shaft 62c. The catching portions 103-4 and 203-4 for capturing the other end portion 63c of the torsion spring 63 are disposed in the cavity portions 103-1 and 203-1.

According to the above structure, the rollers 103 and 203 can be embodied, wherein one end portion 103-1 and 203-1 are rotatably supported on the frames 150 and 250, and the other end portions 103-2 and 202-3 can be pulled. The applying portion 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 winding up the rollers 103 and 203 can be applied to the display 301 by rotating the rotary support member 60 in the direction D1. The pulling force in the direction in which the display 301 is flatly expanded can be applied to the display 301 by the initial elastic force F1.

In a state where the initial elastic force F1 is active, when the rotary support member 60 is in a free state in which the rotation of the rotary support member 60 is not restrained, the rotary support member 60 is in the opposite direction to the direction D1 by the initial elastic force F1. The rotation on D2, and thus the initial spring 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 coupled 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 coupled to at least one of the first support member 6-1 and the second support member 6-2 and locked in a state in which 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, the rotary support member 60 is correspondingly rotated. For example, the rotating support member 60 can be coupled to the sprockets 195, 196, 295, and 296. Therefore, when the sprockets 195, 196, 295, and 296 are not rotated, the rotation support member 60 does not rotate to be locked. When the sprockets 195, 196, 295, and 296 are rotated, the rotation support member 60 rotates.

Figure 30 is a perspective view of a connection structure of the rotary support member 60 and the sprockets 195, 196, 295, and 296, in accordance with an embodiment of the present invention. Referring to Figures 27, 28 and 30, the gear portion 61b is disposed on a rotary support member 60 (e.g., bush member 61). The gear portion 61b is coupled to the sprockets 195, 196, 295, and 296. For example, the gear portion 61b is coupled to a gear 1501 disposed on the sprocket 196 (296) via gears 1507 through 1510. Since the rotational directions of the rollers 103 and 203 and the rotational support member 60 are perpendicular to the rotational direction of the sprocket 196 (296), one of the gears 1507 to 1510 has a structure capable of changing the rotational direction by 90°. For example, gear 1510 can include a spur gear portion 1510a coupled to gear 1509 and a helical gear portion 1510b that rotates coaxially with spur gear portion 1510a. The gear portion 61b is a helical gear that meshes with the helical gear portion 1510b. According to the above configuration, the rotation support member 60 rotates interlockingly with the rotation of the sprocket wheels 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 is applied to the drums 103 and 203 and the helical gear portion by the initial elastic force F1 in the direction in which the display 301 is rolled up by rotating the rotary support member 60 in the direction D1 The 1510b is engaged and the rotary support member 60 can be maintained in the stated state. In this state, when the first bodies 101 and 201 are approached/disengaged from the second body 401 and thus the display 301 is unfolded/rolled back from the first bodies 101 and 201 into the first body, The rollers 103 and 203 and the rotation support member 60 rotate in the direction in which the display 301 is unfolded or in the direction in which the display 301 is rolled up.

FIG. 31 is a graph showing the relationship between the extended distance of the display 301, the amount of rotation of the rollers 103 and 203, and the amount of rotation 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 drums 103 and 203 are actually rotated, but indicates a relative rotation amount with respect to the initial elastic force F1 applied to the rotation support member 60.

The amount of rotation of the rollers 103 and 203 does not have a linear proportional relationship with the extended distance of the display 301. This is because the outer diameter of each of the rollers 103 and 203 including the display 301 is changed according to the amount of the display 301 wound around the rollers 103 and 203. In other words, when the amount by which the display 301 is wound around the rollers 103 and 203 is relatively small, the amount of rotation of the rollers 103 and 203 with respect to the change of the same extended distance is larger than the amount of rotation of the display 301 in a state where the amount of winding around the rollers 103 and 203 is relatively large. . Therefore, the relationship between the extended distance and the amount of rotation of the rollers 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.

When the rotation support member 60 has a structure that does not rotate, the rotation amount of the rollers 103 and 203 is "d2" in a state where the display 301 is completely deployed outward from the first bodies 101 and 201. The amount of the elastic force F2 supplied from the torsion spring 63 to the rollers 103 and 203 is proportional to the amount of rotation d2. Therefore, in a state where the display 301 is completely deployed outward from the first bodies 101 and 201, an extremely strong elastic force F2 is applied to the rollers 103 and 203. Therefore, as the extended distance of the display 301 increases, a large force is required to separate the first bodies 101 and 201 from the second body 401.

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

The amount of elastic force applied to the rollers 103 and 203 by the torsion spring 63 is proportional to the difference between the amount of rotation of the rollers 103 and 203 and the amount of rotation of the rotary support member 60. In other words, the amount of spring force applied to the rollers 103 and 203 by the torsion spring 63 is proportional to the amount of rotation d4 when the display 301 is fully deployed outward from the first bodies 101 and 201. Therefore, according to the present embodiment in which the rotary support member 60 rotates together with the rollers 103 and 203, the elastic force F2' is smaller than the structure in which the rotary support member 60 does not rotate when the display 301 is fully deployed outward from the first bodies 101 and 201. The elastic force F2. Therefore, the change in the amount of the elastic force applied to the rollers 103 and 203 in the expansion program of the display 301 (that is, the change in the amount of the tension applied to the display 301) can be reduced, and thus 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 E2a of the straight line E2 can be adjusted by causing one or more of the gears 1507 to 1510 to be 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 larger than when the display 301 is to be unfolded or wound. The extended distance maintains the display 301 flat as necessary and produces the value of the minimum spring force required to rotate the drums 103 and 203. The inclination angle E2a of the straight line E2 can be set to be the same as the inclination angle E3a of the straight line E3 connecting the initial rotation amount with the final rotation amount of the drums 103 and 203. Therefore, the amount of change in the elastic force applied to the rollers 103 and 203 by the torsion spring 63 in accordance with the extended distance of the display 301 can be reduced.

Although the display 301 is flared from the first body 101 and 201 by manually causing the first body 101 and 201 to be manually approached/separated from the second body 401 / the display 301 is rolled back to the The structures in the first bodies 101 and 201 are described in the above embodiments of the present invention, but by allowing the first bodies 101 and 201 to approach/detach from the second body 401 by using a motor. It is possible that a body 101 and 201 are flared out of the display 301/the structure in which the display 301 is rolled back into the first bodies 101 and 201. In one example, the motor rotates the first sprocket 195, 295 and the second sprocket 196, 296 to move the first support member 6-1 and the second support member 6-2 such that the first body 101 and 201 approach the second The body 401 is separated from the second body 401, thereby causing the display 301 to expand outward from the first bodies 101 and 201/rewind the display 301 back into the first bodies 101 and 201. Referring to Figures 27 and 30, the rotatable display device can include a motor 1500. Motor 1500 rotates gear 1507. Gear 1507 is coupled to gear 1501 disposed in sprocket 196. According to the above configuration, when the first sprocket 195, 295 and the second sprocket 196, 296 are rotated in the unfolding direction by driving the motor 1500 in the forward direction, the first support member 6-1 and the second support member 6-2 is extended outward from the first bodies 101 and 201. Next, as the first bodies 101 and 201 are spaced apart from the second body 401, the display 301 is expanded outward from the first bodies 101 and 201 to expand between the first bodies 101 and 201.

In contrast, when the first sprocket 195, 295 and the second sprocket 196, 296 are rotated in the accommodating direction by driving the motor 1500 in the reverse direction, the first support member 6-1 and the second support member The 6-2 is 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 rotary support member 60 is rotatable in proportion to the extended distance of the display 301.

Figure 32 is a partial perspective view of a rotatable display device in accordance with an embodiment of the present invention. Figure 33 is a cross-sectional view taken along line G-G' of Figure 32.

Referring to Figures 32 and 33, the segment link 601 has a shape that can protect the edges 301a and 301b of the display 301. Each of the segmented links 601 includes ribs 601c that extend from the rear surface 301-2 of the display 301 over the edges 301a and 301b to the image display surface 301-1. The ribs 601c cover the edges 301a and 301b of the display 301. In a state where the display 301 is expanded, the edges 301a and 301b may be damaged by an external impact. According to an embodiment of the invention, the edges 301a and 301b are covered by ribs 601c. Therefore, the possibility of damage to the edges 301a and 301b of the display 301 can be reduced.

Figure 34 is a schematic plan view of a rotatable display device in accordance with an embodiment of the present invention.

Referring to Fig. 34, the first support member 6-1 and the second support member 6-2 support the central portion of the display 301 in the width direction A2. In FIG. 34, the first support member 6-1 and the second support member 6-2 may be positioned adjacent to each other in the width direction A2, or configured to be separated from each other by a certain distance. The pivoting directions of the segment link 601 of the first support member 6-1 and the second support member 6-2 are opposite to each other.
