  The keyboard 102, which is an example of the input device according to the first embodiment, will be described in detail with reference to the drawings.

  As shown in FIG. 1, the keyboard 102 has a housing 104. The housing 104 is a flat plate-shaped member and can be installed on an installation surface 80 (see FIG. 2) such as a desk or a table. The width direction, the depth direction, and the thickness direction in the state where the housing 104 is installed in this way are indicated by arrows W, arrows D, and T, respectively. Further, when simply referred to as “front side” and “back side”, it means the front side and the front side in the depth direction of the housing 104, respectively, and is indicated by arrow DA and arrow DB.

  A connection plate 106 is provided on the inner side 104B located on the inner side of the housing 104. The keyboard 102 is electrically connected to the electronic device 82 via the connection plate 106. The electronic device 82 may be, for example, a tablet computer, a smartphone, or the like. The electronic device 82 shown in FIG. 1 has a device housing 88 including a display 84 and a support leg 86 on the opposite side of the display 84. By projecting the support legs 86 from the device housing 88, the device housing 88 can be maintained in an inclined posture on the installation surface 80 as shown in FIG. Further, the keyboard 102 can be placed in a state of being overlapped with the electronic device 82 as shown in FIG.

  An input key 112 and a touch pad 114 are provided on a first surface 108 that is one surface in the thickness direction of the housing 104. The input key 112 and the touch pad 114 are both examples of an input unit that receives an input operation.

  A wall member 116 is provided on the second surface 110 of the housing 104, that is, the surface (rear surface) opposite to the surface on which the input keys 112 and the touch pad 114 are provided. The wall member 116 is provided on the back side (arrow DB side) of the center line CL-1 in the depth direction of the housing 104.

  As shown in FIGS. 4 to 9, the wall member 116 has a pair of (two) first wall plates 118A and 118B and one second wall plate 120. In addition, in the example shown in FIG. 4, the first wall plate 118A and the second wall plate 120 are divided into two in the width direction by the bent portion 130 described later, but the first wall plate 118A and the second wall plate 118A are divided into two. The wall plate 120 may have a shape that is not divided in this way.

  A base plate 148 integral with the second surface 110 is provided on the second surface 110 of the housing 104. The base plate 148 is attached in parallel with the second surface 110 in a storage recess 146 described later. Substantially, the base plate 148 is a part of the second surface 110 (back surface) of the housing 104.

  The front side first wall plate 118A is rotatably attached to the front side end of the base plate 148 by a first hinge 122A, and the back side first wall plate 118B is a base by a first hinge 122B. The plate 148 is rotatably attached to the rear end. Both the first hinge 122A and the second hinge 124B are parallel to the inner side 104B of the housing 104. Therefore, the first hinge 122A and the second hinge 124B are also parallel to each other.

  The first wall plates 118A and 118B rotate about the first hinges 122A and 122B, respectively, so that the first wall plates 118A and 118B project from the housing 104 in an overlapping posture KP (see FIG. 4) parallel to the second surface 110 of the housing 104. The projected posture TP (see FIG. 8) is adopted.

  The second wall plate 120 is rotatably attached to the first wall plate 118A by a second hinge 124A, and is rotatably attached to the first wall plate 118B by a second hinge 124B. Both the second hinge 124A and the second hinge 124B are parallel to the inner side 104B. Therefore, the first hinge 122A, the first hinge 122B, the second hinge 124A, and the second hinge 124B are parallel to each other.

  As shown in FIGS. 8 and 9, the wall member 116 is orthogonal to the first hinge 122A when viewed in the direction along the first hinge 122A when the first wall plates 118A and 118B are in the protruding posture TP. A cylindrical body 126 having a parallelogram cross section is formed. That is, the distance between the first hinges 122A and 122B is equal to the distance between the second hinges 124A and 124B. The depth of the first hinge 122A and the depth of the first hinge 122B are also equal (this depth is D1). In other words, the shapes of the first wall plates 118A, 118B, the second wall plate 120, and the base plate 148 are set so that the cross section of the tubular body 126 is a parallelogram.

  In this embodiment, the depth D1 of the first wall plates 118A and 118B is equal to the depth D2 of the second wall plate 120 and the base plate 148. Therefore, the cross-sectional shape of the cylindrical body 126 is a rhombus. In particular, when the first hinges 122A and 122B are at a right angle, the cylindrical body 126 has a square cross-sectional shape, and the wall member 116 is in a protruding state TS protruding from the second surface 110 of the housing 104. On the other hand, when the first wall plates 118A and 118B are in the overlapping posture KP, the second wall plate 120 overlaps the first wall plate 118B as shown in FIGS. 4 and 5. Then, the wall member 116 as a whole is in a folded state PS folded in a plate shape. The depth D1 of the first wall plates 118A and 118B is also the height of the wall member 116 from the storage recess 146 when the wall member 116 is in the protruding state TS.

  The wall member 116 is provided with a cutout 128. In the first embodiment, as shown in FIGS. 4, 6 and 8, the cut portions 128 are provided in pairs (two) at symmetrical positions with respect to the center line CL-2 in the width direction of the housing 104. Has been.

  Each of the cut portions 128 is provided by cutting the first wall plate 118A from the position of the second hinge 124B on the back side to the position of the first hinge 122A on the front side through the position of the second hinge 124A on the front side. Has been. In the wall member 116, a portion between the pair of cut portions 128 is the bent portion 130.

  As shown in FIGS. 4 and 6, the wall member 116 is provided with third hinges 132A, 132B, 132C. Specifically, at the position of the second hinge 124B, the boundary between the wall member 116 (first wall plate 118B on the back side) and the bent portion 130 is the third hinge 132A. Further, in the bent portion 130, third hinges 132B and 132C are provided between the first hinge 122A and the third hinge 132A on the front side.

  As shown in FIG. 9, the position of the third hinge 132B is such that the distance D3 from the third hinge 132A to the third hinge 132B is √2 times the depth D1 of the first wall plates 118A and 118B, or slightly. The position is set to be shorter. The position of the third hinge 132C is set at the center of the third hinge 132B and the first hinge 122B. The bent portion 130 can be folded inside the tubular body 126 as shown in FIGS. 8 and 9. The portion from the third hinge 132A to the third hinge 132B is a bridging member 134 that bridges the first hinge 122B and the second hinge 124A in the tubular body 126. Therefore, the bridging member 134 is also a member that is laid across the first wall plate 118A and the first wall plate 118B in an oblique posture with respect to the second surface 110.

  In this state, in the bent portion 130, the portion from the third hinge 132B to the third hinge 132C is the first overlapping plate 136 located in the direction away from the second surface 110. Further, in this state, the portion from the third hinge 132C to the first hinge 122B is folded back from the first polymer plate 136 and polymerized with the first polymer plate 136, and the second polymer plate 138 continuous with the second surface 110. Is.

  As shown in FIG. 9, a magnet member 140 is embedded in the first superposed plate 136 and the second superposed plate 138. The first overlapping plate 136 and the second overlapping plate 138 are attracted to each other by the magnetic force of the magnet member 140. Examples of the magnet member 140 include a magnet 142 embedded in the first polymer plate 136 and an adsorbent 144 embedded in the second polymer plate 138 and attracted by the magnetic force of the magnet 142. Note that, conversely, the magnet 142 may be embedded in the second polymer plate 138 and the adsorbent 144 may be embedded in the first polymer plate 136.

  As shown in FIGS. 4 to 9, a housing recess 146 is provided on the second surface 110 of the housing 104. The storage recess 146 has a shape in which the first wall plates 118A and 118B are in the overlapping posture KP, the wall member 116 is folded as a whole, and has a position and a size for storing the wall member 116. Then, when the wall member 116 is stored in the storage recess 146, the outer surface 116S of the folded wall member 116 (the outer surfaces of the first wall plate 118A and the second wall plate 120) is the second surface of the housing 104. It is flush with 110.

  Next, the operation of this embodiment will be described.

  As shown in FIGS. 4 and 5, the wall member 116 of the keyboard 102 is stored in the storage recess 146 of the second surface 110 when in the folded state PS. Then, from this state, as shown in FIGS. 6 and 7, the first wall plates 118A and 118B can be rotated in the arrow R1 direction around the first hinges 122A and 122B toward the projecting posture TP. it can. During the rotation, as shown in FIG. 7, the cross-sectional shape of the wall member 116 becomes a rhombus. Then, as shown in FIGS. 8 and 9, when the angles of the first hinges 122A and 122B are 90 degrees, the wall member 116 (cylindrical body 126) has a square cross-sectional shape. Since the wall member 116 protrudes from the second surface 110 of the housing 104, when the housing 104 is installed on the installation surface 80 with the second surface 110 facing down as shown in FIG. It is supported in a posture inclined with respect to the installation surface 80 (tilt posture).

  Thus, the wall member 116 and the base plate 148 (a part of the second surface 110) form a parallelogram with a hollow inside as a whole. Then, the wall member 116 is folded into a plate shape in a state of being housed in the housing recess 146 of the housing 104. By being folded in this manner, the wall member 116 is thinner than, for example, a leg portion having a shape having a predetermined thickness to obtain strength. As a result, the thickness T1 of the housing 104 when the wall member 116 is in the folded state can be reduced.

  In particular, the housing 104 is provided with a storage recess 146. Since the thinly folded wall member 116 is stored in the storage recess 146 of the housing 104, the depth of the storage recess 146 can be shallow. Since the depth of the storage recess 146 can be reduced, the thickness of the housing 104 can also be reduced.

  The keyboard 102 has a bridging member 134. The bridging member 134 of the present embodiment is bridged between the first hinge 122B and the second hinge 124A when the tubular body 126 has a square cross-sectional shape. As shown in FIG. 2, a load acts on the keyboard 102 from the first surface 108 side, and even if the tubular body 126 is likely to be crushed in the direction in which the first hinge 122B and the second hinge 124A approach each other, The bridging member 134 acts as a bracing member in the compression direction. As a result, the tubular body 126 can maintain a state in which its cross-sectional shape is square. Then, the housing 104 can be maintained in a posture inclined at a predetermined angle (tilt posture).

  As the bridging member 134, for example, if the bridging member 134 is bridged over any one of the pair of first wall plates 118A and 118B, the second wall plate 120, and the second surface 110, the force for crushing the tubular body 126. Even if is applied, it is possible to prevent the cylindrical body 126 from being actually crushed.

  Therefore, the bridging member 134 may be configured to be bridged between the pair of first wall plates 118A and 118B. However, if the bridging member 134 is bridged in parallel with the second surface 110, the effect of suppressing the collapse of the tubular body 126 having a parallelogram cross section is small. On the other hand, in the structure in which the bridging member 134 is slid over the second surface 110, it is possible to effectively suppress the collapse of the tubular body 126.

  In the first embodiment, the bridging member 134 is bridged between the first hinge 122B and the second hinge 124A. A line segment connecting the first hinge 122B and the second hinge 124A is a diagonal line of the parallelogram cylinder 126. In other words, the interval between the first hinge 122B and the second hinge 124A is a portion where the dimensional change is large when the tubular body 126 is crushed, and the bridging member 134 is braced at the portion where the dimensional change is large. Therefore, the effect of suppressing the collapse of the cylindrical body 126 is high.

  The first embodiment has a structure having the cutout portion 128 and the third hinges 132A, 132B, 132C. As a result, a part of the wall member 116 serves as the bent portion 130. Then, by bending the bent portion 130 with the third hinge, the bridging member 134 can be formed by using a part of the bent portion 130. Since a structure having the bridging member 134 can be realized by effectively using a part of the wall member 116, it is not necessary to provide the bridging member 134 as a separate member, and an increase in the number of parts can be suppressed.

  A pair of cutouts 128 is provided on the wall member 116 in a direction intersecting with the first hinge 122A and continuously from the first wall plate 118B to the second wall plate 120. The bent portion 130 is located as a part of the first wall plate 118B and the second wall plate 120 in the central portion in the width direction of the wall member 116. This makes it possible to realize a structure in which the bridging member 134 is located at the central portion of the wall member 116 in the width direction.

  The bent portion 130 further includes a first overlapping plate 136 and a second overlapping plate 138. In the bent portion 130, a portion other than the bridging member 134 is continuous from the bridging member 134 to the second surface 110 via the first overlapping plate 136 and the second overlapping plate 138. Since the bent portion 130 has an integrated structure including the portions other than the bridging member 134 (the first overlapped plate 136 and the second overlapped plate 138), it is easy to handle.

  Moreover, the first polymerized plate 136 and the second polymerized plate 138 are polymerized in a state where a part of the bent portion 130 forms the bridging member 134. That is, in the state where a part of the bent portion 130 forms the bridging member 134, the space for fastening the parts other than the bridging member 134 can be reduced.

  A magnet member 140 is embedded in the first superposed plate 136 and the second superposed plate 138, and the first superposed plate 136 and the second superposed plate 138 are attracted by a magnetic force. This makes it possible to stably maintain the state in which the first polymerization plate 136 and the second polymerization plate 138 are polymerized.

  Further, while the bent portion 130 is folded by the third hinges 132A, 132B, 132C to form the bridging member 134, the first polymerized plate 136 and the second polymerized plate 138 are approached by the magnetic force of the magnet member 140. To be done. Therefore, the work of forming the bridging member 134 on the bent portion 130 is easy.

  The magnet member 140 is embedded in the first superposed plate 136 and the second superposed plate 138, and does not protrude from the first superposed plate 136 and the second superposed plate 138. Therefore, for example, in the state where the wall member 116 is folded in a plate shape, it is possible to realize a structure in which the portion of the first overlapping plate 136 and the second overlapping plate 138 where the magnet member 14 is provided does not protrude from the housing 104.

  Next, a second embodiment will be described. In the second embodiment, elements and members similar to those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. Further, in the second embodiment, the overall structure of the keyboard 202 can be the same as that of the keyboard 102 of the first embodiment, and therefore the illustration thereof is omitted.

  As shown in FIGS. 10 and 11, in the keyboard 202 of the second embodiment, the wall member 116 is provided with the notches 228 at positions on both sides in the width direction. Specifically, at the positions of the first hinge 122A, the second hinge 124A, the first hinge 122B, and the second hinge 124B, they extend from both ends in the width direction toward the center along these hinges (ridge lines in the wall member 116). A cut portion 228 is provided with a predetermined length.

  A third hinge 232 is provided on each of the first wall plates 118A and 118B at a position of an end of the cut portion 228 (a position near the center in the width direction). In the first wall plate 118A, the portions located on both sides of the third hinge 232 in the width direction are the bent portions 230A. Similarly, in the first wall plate 118B, the portions located on both sides of the third hinge 232 in the width direction are the bent portions 230B. That is, in the second embodiment, the bent portions are provided on both the first wall plate 118A and the first wall plate 118B.

  In the second embodiment, at a stage in the middle of rotating the first wall plates 118A and 118B in the overlapping posture KP in the arrow R1 direction about the first hinges 122A and 122B, as shown in FIG. The first wall plates 118A and 118B are not bent at the position. That is, the first wall plates 118A and 118B maintain a flat state.

  In the second embodiment, as shown in FIG. 12, in the state where the wall member 116 forms the cylindrical body 126 having a square cross-sectional shape, the end portion in the width direction of the first wall plate 118A is connected to the third hinge. The bridging member 234 </ b> A can be formed by bending the tubular body 126 by the inner portion 232. Similarly, the bridging member 234B can be formed by bending the first wall plate 118B toward the inside of the cylindrical body 126 by the third hinge 232. When the tubular body 126 is about to be crushed, the bridging members 234A and 234B act as a bracing between the base plate 148 and the second wall plate 120 of the housing 104, and it is possible to suppress the crushing of the tubular body 126. .

  In the second embodiment, the cut portion 228 corresponding to the bent portion 230A is at the position of the first hinge 122A and the second hinge 124A, and the cut portion 228 corresponding to the bent portion 230B is the first hinge 122B and the first hinge 122B. It is in the position of the two hinges 124B. Therefore, the height H1 of the bridging members 234A and 234B is equal to the distance D4 from the base plate 148 to the second wall plate 120 when the tubular body 126 has a square cross-sectional shape. Therefore, the first wall plates 118A and 118B can be maintained in a state of standing upright at 90 degrees with respect to the second surface 110.

  In the example shown in FIG. 12, the widths WA of the bridging members 234A and the widths WB of the bridging members 234B are longer than the depth D2 of the second wall plate 120, so that the bridging members 234A and 234B may be made larger. The widths WA and WB of each are set. Therefore, the tip portions of the bridging members 234A and 234B can be abutted against each other. In particular, in a state in which the leading end portions of the bridging members 234A and 234B are butted against each other, a projecting portion 234D that is projected from the butted portion is formed further on the leading end side of the bridging member 234A. By gripping the protrusion 234D, the bridging member 234A can be rotated around the third hinge 232. Note that the protruding member 234D may be formed on the tip end side of the bridging member 234B instead of the bridging member 234A.

  Next, a third embodiment will be described. In the third embodiment, elements and members similar to those in the first or second embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. Further, in the third embodiment, the overall structure of the keyboard 302 may be the same as that of the keyboard 102 of the first embodiment, and therefore the illustration thereof is omitted.

  As shown in FIG. 13, in the keyboard 302 of the third embodiment, the wall member 116 is provided with notches 328 at positions on both sides in the width direction. Specifically, at the positions of the first hinge 122A and the second hinge 124A, the notch 328 is provided with a predetermined length from both ends in the width direction toward the center.

  On the first wall plate 118A, a third hinge 332 is provided at a position of an end of the cut portion 328 (a position near the center in the width direction). In the first wall plate 118A, the bent portions 330 are located on both sides of the third hinge 332 in the width direction. As shown in FIG. 15, the bridging member 330 can be formed by bending the bent portion 330 inside the cylindrical body 126 by the third hinge 332.

  In the example shown in FIG. 13, the width W1 of the first wall plate 118A is longer than the width W2 of the second wall plate 120. A fourth hinge 348 is provided on the end portion side of the bent portion 330 in the width direction. As a result, as shown in FIG. 15, with the bridging member 334 formed, the bent portion 330 can be projected outward in the width direction to form the protruding portion 350.

  In the third embodiment, as shown in FIG. 15, when the first wall plates 118A and 118B are in the projecting posture TP, the bent portion 330 is bent by the third hinge 332 to form the bridging member 334. You can The bridging member 334 contacts the second surface 110 of the housing 104 and the second wall plate 120. Therefore, when the tubular body 126 is about to be crushed, the bridging member 334 comes into contact with the second surface 110 of the housing 104 and the second wall plate 120, so that the crushing can be suppressed.

  In the third embodiment, since the notch 328 is located at the position of the first hinge 122A and the second hinge 124A, the height H1 of the bridging member 334 from the base plate 148 when the tubular body 126 has a square shape. It corresponds to the distance D4 to the second wall plate 120. For this reason, it is easy to maintain the first wall plates 118A and 118B in a state of standing upright at 90 degrees with respect to the second surface 110.

  Further, since the projecting portion 350 is formed on the bridging member 334, the projecting portion 350 can be gripped and the bridging member 334 can be rotated around the third hinge 132B.

  Next, a fourth embodiment will be described. In the fourth embodiment, elements, members and the like similar to those in the first embodiment, the second embodiment or the third embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. Further, in the fourth embodiment, the overall structure of the keyboard 402 can be the same as that of the keyboard 102 of the first embodiment, and therefore the illustration thereof is omitted.

  As shown in FIG. 16, in the keyboard 402 of the fourth embodiment, the wall member 116 is provided with notches 328 at positions on both sides in the width direction. Specifically, at the positions of the second hinges 124A and 124B, the notch 428 is provided with a predetermined length from both ends in the width direction toward the center.

  The second wall plate 120 is provided with a third hinge 432 at a position of an end of the cut portion 428 (a position near the center in the width direction). In the second wall plate 120, the bent portions 430 are located on both sides of the third hinge 432 in the width direction. As shown in FIG. 18, the bridging member 434 can be formed by bending the bent portion 430 inward of the cylindrical body 126 by the third hinge 432.

  In the example shown in FIG. 16, a fourth hinge 448 is provided on the widthwise end side of the bent portion 430 in a direction intersecting (orthogonal in FIG. 16) the first hinges 122A and 122B. As a result, as shown in FIG. 18, in the state where the bridging member 434 is formed, the widthwise end portion side of the bent portion 430 can be made to protrude outward in the widthwise direction to form the protruding portion 450. .

  In the fourth embodiment, as shown in FIG. 18, when the first wall plates 118A and 118B are in the projecting posture TP, the bent portion 330 is bent by the third hinge 432, and the first wall plates 118A and 118B are bent. A bridging member 434 can be formed that contacts both. When the tubular body 126 is about to be crushed, the bridging member 434 comes into contact with both the first wall plates 118A and 118B, so that the crushing can be suppressed.

  In the fourth embodiment, since the notch 428 is located at the second hinges 124A and 124B, the height H1 of the bridging members 234A and 234B is the same as that of the base plate 148 when the tubular body 126 has a rectangular shape. It coincides with the distance D4 to the two-wall plate 120. For this reason, it is easy to maintain the first wall plates 118A and 118B in a state of standing upright at 90 degrees with respect to the second surface 110.

  Further, since the projecting portion 450 is formed on the bridging member 434, the projecting portion 450 can be gripped and the bridging member 434 can be rotated around the third hinge 432.

  Next, a fifth embodiment will be described. In the fifth embodiment, elements and members similar to those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. Further, in the fifth embodiment, the overall structure of the keyboard 502 may be the same as that of the keyboard 102 of the first embodiment, and therefore the illustration thereof is omitted.

  As shown in FIG. 19, in the keyboard 502 of the fifth embodiment, the bridging member 534 has a structure separate from the wall member 116. The bridging member 534 has, for example, a cylindrical portion 534A having a diameter D5 that is the same as or slightly smaller than the distance D4 from the base plate 148 to the second wall plate 120. When the cylinder 126 is about to be crushed in a state where the cylinder 534A is inserted inside the cylinder 126, the cylinder 534A may contact the base plate 148 and the second wall plate 120 of the housing 104. Therefore, it is possible to suppress the crushing.

  As the bridging member 534 of the fifth embodiment, for example, a pen, a pencil, a ruler or the like as a writing instrument is used in addition to a touch pen used for a touch operation on the electronic device 82 (see FIGS. 1 and 2). You can As shown in FIG. 19, if the bridging member 534 includes the clip portion 534B, by hooking the bridging member 534 on the first wall plate 118A (or the first wall plate 118B) using the clip portion 534B, It is possible to prevent the bridging member 534 from shifting or coming off from the cylindrical body 126.

  In the fifth embodiment, the structure of the bridging member 534 is not limited to the above structure. For example, a rod-shaped or plate-shaped member that forms a brace between the first hinge 122B and the second hinge 124A may be provided separately from the wall member 116.

  Next, a reference example will be described. In the reference example, elements and members similar to those of the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. Further, in the reference example, the entire structure of the keyboard 902 may be the same as that of the keyboard 102 of the first embodiment, and therefore the illustration thereof is omitted.

  As shown in FIG. 20, the keyboard 902 of the reference example has a first rotary plate 920 and a second rotary plate 922 as the wall plate 918. One end 922 </ b> A (back end) of the first rotating plate 920 is rotatably connected to the second surface 110 of the housing 104 by the first connecting portion 924. Then, the first rotary plate 920 rotates between the overlapping posture KP and the protruding posture TP. In the overlapping posture KP, the first rotary plate 920 is stored in the storage recess 146 in parallel with the second surface 110. In the projecting position TP, the first rotating plate 920 projects from the second surface 110.

  In this way, the first connecting portion 924 rotatably connects the first rotating plate 920 to the housing 104, and a hinge can be given as an example thereof.

  One end 922A of the second rotating plate 922 in the depth direction is rotatably connected to one end 920B of the first rotating plate 920 in the depth direction by a second connecting portion 926. Then, the second rotary plate 922 rotates between the overlapping posture KP and the protruding posture TP. In the overlapping posture KP, the second rotary plate 922 overlaps the second surface 110 together with the first rotary plate 920 in the overlapping posture KP. In the projecting position TP, the second rotary plate 922 projects from the second surface 110 by being bridged from the one end 920B of the first rotary plate 920 in the projecting position TP toward the second surface 110. In this way, the second connecting portion 926 rotatably connects the second rotary plate 922 to the first rotary plate 920, and a hinge portion can be given as an example thereof.

  Then, in the reference example, the plurality of wall plates 918 (the first rotary plate 920 and the second rotary plate 922) have a protruding state TS that protrudes from the second surface 110 and a folded state that is folded in the housing 104. Take PS and.

  The second surface 110 of the housing 104 is provided with a fitting portion 928 into which the other end 922B of the second rotary plate 922 in the protruding posture TP fits. When the other end 922B of the second rotary plate 922 is fitted into the fitting portion 928, the second rotary plate 922 is held in the protruding posture TP.

  Also in the reference example, as shown in FIG. 22, by setting the wall plate 918 in the protruding state TS, the housing 104 can be supported in the tilted posture. Further, as shown in FIG. 20, since the wall plate 918 is folded in the housing 104 in the folded state PS, it is possible to reduce the thickness of the housing 104.

  In the above description, the first wall plates 118A, 118B and the second wall plate 120 each have an example of a single plate shape. However, a plurality of plate materials are connected to each other or these members are stacked. It may have a different structure. For example, if a hinge is newly provided at an intermediate portion of the second wall plate 120 in the depth direction so that the second wall plate 120 can be bent at the intermediate portion, the cross section of the tubular body 126 can be a shape other than a parallelogram. The degree of freedom of the shape of the cylindrical body 126 is high. However, even in this case, if the tubular body 126 has a structure in which the cross-sectional shape is a parallelogram, the wall member 116 can be folded into the housing 104 and folded over the second surface 110. The housing 104 can be thinned.

  The structure of the wall member may be a combination of the structures of the above embodiments. For example, the structure having the bent portion 130 of the first embodiment and the structure having the bent portions 230A and 230B of the second embodiment or the bent portion 330 of the third embodiment can be combined. By combining the bent portion 130 of the first embodiment and the bent portions 230A and 230B of the second embodiment, a structure having the bridging member 134 and the bridging members 234A and 234B can be realized.

  In the above, the structure including the input key 112 and the touch pad 114 is described as an example of the input device, but the input unit that receives an input to the input device is not limited thereto. For example, it may be an input unit that rotates and inputs a rotating body that is rotatably held in the housing 104, or an input unit that reads card information of a specific card in a contact or non-contact manner. These input units may be provided alone in the housing 104, or may be provided by combining a plurality of types of input units.

  Further, the structure of each of the above embodiments can be applied to an information processing device such as a notebook computer. That is, in a laptop computer, for example, a housing is provided with a processor, a storage device, an input terminal, an output terminal, a communication member (antenna), a keyboard 112, a touch pad 114, and the like (see FIG. 1 for all). Then, the display is rotatably attached to the housing by a hinge or the like. The display is electrically connected to the housing and displays predetermined information as an image on the display screen of the display. In the notebook computer having such a structure, the structure of each of the above-described embodiments can be applied to the case, that is, the member having the keyboard.
