Therefore, the user has the trouble of carrying and using the digitizer and notebook.

JP 2002-132944 A

  When a user carries a notebook with a notebook attached to the digitizer, a pair of notebook covers may be attached to each of the pair of digitizers that can be folded between the two, and the notebook can be opened and closed for each digitizer. However, the positional relationship between the pair of covers located on the inner peripheral side of the rotation when the notebook is opened and closed and the positional relationship between the pair of digitizers positioned on the outer peripheral side differ between when the notebook is opened and when it is closed. . Therefore, the cover of the notebook may be bent or bent.

  An object of the present invention is to provide an information input device that can change the positional relationship between a pair of detection devices in accordance with the opening and closing of a booklet-shaped recording medium.

  According to the aspect of the present invention, a pair of cover sheets and a plurality of sheets arranged to overlap between the pair of cover sheets are bound on a part of each edge portion on the booklet-shaped recording medium. An information input device capable of acquiring information input by a writing instrument, having a first detection surface, and a plate-like body capable of detecting the position of the writing instrument proximate to the first detection surface, A plate-like shape having a first detection device that can be disposed opposite to substantially the entire surface of the first cover of the pair of covers, and a second detection surface that can detect the position of the writing instrument adjacent to the second detection surface. A second detection device that can be disposed opposite the substantially entire surface of the second cover of the pair of covers, and a member that connects the first detection device and the second detection device, The first detection device is disposed opposite to the first back surface, which is the surface opposite to the first detection surface, and the first detection device A first holding unit that holds the device so as to be relatively movable in a direction approaching and separating from the second detection device, and a surface opposite to the second detection surface of the second detection device. A second holding portion that is disposed opposite to the second back surface and holds the second detection device so as to be relatively movable in a direction toward and away from the first detection device; and the first holding portion; The second holding part is connected, and the first detection surface and the second detection surface are close to each other and can be bent in a first direction and a second direction opposite to the first direction. A connecting member having a bent portion, and a conductive member that electrically connects the first detection device and the second detection device between the first detection device and the second detection device. Information input characterized by comprising a connecting member that can be expanded and contracted according to changes in the position of Location is provided.

  The first holding unit and the second holding unit that respectively hold the first detection device and the second detection device relatively move the first detection device and the second detection device, and the first detection device and the second detection device. Can be close and spaced apart. Therefore, when the recording medium is opened and closed, the first detection device and the second detection device can move relatively in accordance with the positions of the first cover and the second cover of the recording medium, respectively. The information input device can prevent the recording medium from being bent without applying a load to the recording medium in alignment with the recording medium. And since a connection member has a stretching property, even if a 1st detection apparatus and a 2nd detection apparatus move relatively, the electrical connection of a 1st detection apparatus and a 2nd detection apparatus can be maintained. it can.

  In this aspect, the connection member may be in an extended state when the bent portion is bent in the first direction. When the bent portion is bent in the second direction, the bent portion may be in a contracted state. The connection member can follow the change in the positional relationship between the first detection device and the second detection device due to bending of the bent portion by expanding and contracting, and the electrical connection between the first detection device and the second detection device Can be maintained.

  In this aspect, the connecting member has a portion that is curved in an arc shape protruding along a second direction orthogonal to the first direction in which the connecting member extends, and a curvature at a protruding tip according to expansion and contraction of the connecting member. A changing curved portion may be formed. When the bent portion is bent in the first direction, the curvature of the curved portion may be reduced. When the bent portion is bent in the second direction, the curvature of the curved portion may be increased. The connecting member expands and contracts by an action in which the curvature of the bending portion changes and the opening angle widens or narrows. Even if the recording medium is repeatedly opened and closed, and the distance between the first detection device and the second detection device is repeatedly changed, the connection member can be reliably expanded and contracted. An electrical connection with the device can be maintained. In addition, since the expansion and contraction of the connecting member is performed by changing the curvature of the bending portion, the connecting member can reduce the load applied to the deformation of the bending portion and can improve the durability.

  In this aspect, the connection member may further include a protection member that protects the connection member. The connection member may be disposed between the protection member and the bent portion. In a state where the connection member is contracted, the length of the bending portion in the second direction may be equal to or less than the length of the gap between the protection member and the bent portion in the second direction. Even when the connecting portion is in a state where the bending portion is bent by contraction, the connecting member is less likely to be caught by the bent portion and the protection member, and can be expanded and contracted more reliably.

  In this aspect, the shape of the connection member at the inflection point may be an arc shape when the connection member is contracted. Even when the connecting member is in a state where the bending portion is bent by contraction, the load related to the inflection point is dispersed, and thus the durability can be improved.

  In this aspect, the connection member includes a plurality of the first bending portions protruding to one side of the second direction and the second bending portions protruding to the other side of the second direction. A curved portion may be formed. The first detection device and the second detection device have a first configuration in which the bent portion is bent in the first direction, and the first detection surface and the second detection surface are close to each other and face each other. A second form in which the bent part is further bent in the second direction from the first form, and the first detection surface and the second detection surface are separated from each other, and the bent part further from the second form. May be arranged in a third form in which the first back surface and the second back surface are close to each other and face each other. The information input device may be easily carried by arranging the first detection device and the second detection device in the first form and sandwiching a recording medium between the first detection device and the second detection device. it can. Moreover, the information input device can expose the writing surface of the recording medium and allow the user to write by arranging the first detection device and the second detection device in the second form. Furthermore, the information input device exposes the writing surface of the recording medium by disposing the first detection device and the second detection device in the third configuration, and folding the first detection device and the second detection device. Can be written by the user. In the deformation to each form, the plurality of bending portions respectively change the curvature, so that the connecting member expands and contracts, and can follow the change in the positional relationship between the first detection device and the second detection device. Therefore, the connection member can maintain the electrical connection between the first detection device and the second detection device.

  A portion of the connecting member that is bent along the crease protrudes along a second direction orthogonal to the first direction in which the connecting member extends, and an inner angle at the protruding tip changes according to expansion and contraction of the connecting member. A bent portion may be formed. When the bent portion is bent in the first direction, the inner angle may be increased. When the bent portion is bent in the second direction, the inner angle may be reduced. The connecting member expands and contracts due to an operation in which the angle inside the bent portion changes and expands or narrows. The bent portion bends regularly along the crease. Therefore, the connection member can expand and contract stably. Even if the recording medium is repeatedly opened and closed, and the distance between the first detection device and the second detection device is repeatedly changed, the connection member can be reliably expanded and contracted. An electrical connection with the device can be maintained.

  In this aspect, the connection member includes a plurality of the first bent portions protruding to one side of the second direction and the second bent portions protruding to the other side of the second direction. A bent portion may be formed. The first detection device and the second detection device have a first configuration in which the bent portion is bent in the first direction, and the first detection surface and the second detection surface are close to each other and face each other. A second form in which the bent part is further bent in the second direction from the first form, and the first detection surface and the second detection surface are separated from each other, and the bent part further from the second form. May be arranged in a third form in which the first back surface and the second back surface are close to each other and face each other. The information input device may be easily carried by arranging the first detection device and the second detection device in the first form and sandwiching a recording medium between the first detection device and the second detection device. it can. Moreover, the information input device can expose the writing surface of the recording medium and allow the user to write by arranging the first detection device and the second detection device in the second form. Furthermore, the information input device exposes the writing surface of the recording medium by disposing the first detection device and the second detection device in the third configuration, and folding the first detection device and the second detection device. Can be written by the user. In the deformation to each form, the plurality of bent portions are regularly bent, so that the connecting member expands and contracts and can follow the change in the positional relationship between the first detection device and the second detection device. Therefore, the connection member can maintain the electrical connection between the first detection device and the second detection device.

  In this aspect, the connection member may further include a protection member that protects the connection member. The connection member may be disposed between the protection member and the bent portion. In a state where the connection member is contracted, the length of the bent portion in the second direction may be equal to or less than the length of the gap between the protective member and the bent portion in the second direction. Even when the bent portion is bent due to contraction, the connecting member is less likely to be caught by the bent portion and the protective member, and can be expanded and contracted more reliably.

  In this aspect, the connection member may include a rubber member that has conductivity and can be expanded and contracted. When the bent portion is bent in the first direction, the length of the connecting member may be a first length extended from a natural length. When the bent portion is bent in the second direction, the length of the connecting member may be contracted more than the first length. The connecting member can be expanded and contracted according to a change in the distance between the first detection device and the second detection device that occurs as the recording medium opens and closes due to the elasticity of the rubber member. Even if the recording medium is repeatedly opened and closed, the connection member can be reliably expanded and contracted, so that the electrical connection between the first detection device and the second detection device can be maintained.

  In this aspect, the connection member may further include a protection member that protects the connection member. The connection member may be disposed between the protection member and the bent portion. Since the connecting member is not exposed by being disposed between the protective member and the bent portion, it is possible to prevent breakage.

The two protrusions engage with the two eyelet holes 43, whereby the slider 60 is fixed to the left cover portion 4L. The detection device 2L is held by the holding sheet 41L while being slidable in the left-right direction with respect to the left cover portion 4L of the exterior cover 4.

  The exterior cover 4 includes a wide band 44 extending in the vertical direction and covering the bent portion 4C on the front side of the bent portion 4C. The belt-like body 44 is woven in the upper and lower edges 45 of the exterior cover 4 in a state where the belt-like body 44 is stretched up and down. The belt-like body 44 has a gap (see FIG. 7) between the front surface of the bent portion 4C. As will be described later, the harness 50 that connects the detection devices 2L and 2R is passed between the strip 44 and the front surface of the bent portion 4C. When the exterior cover 4 is in an open state, the belt-like body 44 covers the harness 50. Although not shown, the exterior cover 4 includes a band that can be used for applications such as a bag, a pocket for storing electronic pens 6, a pocket for storing materials, and the like that support the battery cover body in a closed state.

  The structure of the detection devices 2L and 2R will be described with reference to FIG. As described above, the detection devices 2L and 2R are devices that can detect the position of the electronic pen 6 when the electronic pen 6 approaches by a known electromagnetic induction method. The detection devices 2L and 2R are rectangular bodies that are long in the vertical direction when viewed from the front and have a small thickness in the front-rear direction.

  As illustrated in FIG. 4, the detection device 2R includes a front cover 8R and a rear cover 9R. The front cover 8R and the rear cover 9R are substantially rectangular resin plates that are long in the vertical direction. The positioning portion 23R is provided on the front surface of the front cover 8R. Detection of the proximity position of the electronic pen 6 by a digitizer substrate 7R to be described later is performed on the detection surface 21R. When the front cover 8R and the rear cover 9R are combined, a box-shaped body having an accommodation space is formed.

  The detection device 2R accommodates the digitizer substrate 7R, the control substrate 71R, and the main substrate 10 between the front cover 8R and the rear cover 9R. The digitizer substrate 7R is configured to detect the proximity position of the electronic pen 6. The control board 71R is configured to control the current flowing through the digitizer board 7R. A CPU (not shown) that controls the information input device 1 is mounted on the main board 10. The main board 10 includes components (not shown) such as various switches and connectors such as a power switch, a light emitting element, and a communication unit. These components are accommodated in an accommodating portion 79 provided at the upper right end portion of the front cover 8R. The CPU of the main board 10 can communicate with an external device (not shown) such as a PC located nearby in a wireless or wired manner. The main board 10 is electrically connected to the control board 71R. The control board 71R is provided integrally with the digitizer board 7R at the lower end of the rear surface of the digitizer board 7R.

  The digitizer substrate 7R is a substrate in which a number of elongated loop coils are arranged in each of the X-axis direction (specifically, the left-right direction) and the Y-axis direction (specifically, the vertical direction). The control board 71R generates a magnetic field by causing a current of a specific frequency (excitation transmission current) to flow through each loop coil. As a result, the resonance circuit of the electronic pen 6 adjacent to the digitizer substrate 7R generates an induced magnetic field. A current (signal current) flows through the loop coil by the induced magnetic field. The control board 71R detects a signal current flowing through the loop coil. The CPU of the main board 10 obtains the position coordinates of the electronic pen 6 over time based on the signal current detected by the control board 71R. The CPU generates stroke data indicating the locus of the electronic pen 6 based on the position coordinates. The CPU outputs the stroke data to an external device (such as a PC) connected to the information input device 1.

  Similarly to the detection device 2R, the detection device 2L includes a front cover 8L and a rear cover 9L. The front cover 8L and the rear cover 9L are substantially rectangular resin plates that are long in the vertical direction. The positioning portion 23L described above is provided on the front surface of the front cover 8L. Detection of the proximity position of the electronic pen 6 by a digitizer substrate 7L described later is performed on the detection surface 21L. Although not shown in detail, the upper and lower end portions excluding the left end portion of the front cover 8L are formed in a state of being folded back to the rear side. The rear cover 9L has notches formed along both upper and lower end portions excluding the left end portion. The notch engages with a portion of the front cover 8L that is turned back to the rear side when the detection device 2L is assembled. When the front cover 8L and the rear cover 9L are combined, a box-shaped body having an accommodation space is formed.

  The detection device 2L accommodates the digitizer substrate 7L and the control substrate 71L between the front cover 8L and the rear cover 9L. The digitizer substrate 7L is configured to detect the proximity position of the electronic pen 6. The control board 71L is configured to control the current flowing through the digitizer board 7L. The control board 71L is provided integrally with the digitizer board 7L at the lower end of the rear surface of the digitizer board 7L. The digitizer board 7L and the control board 71L have the same configuration as the digitizer board 7R and the control board 71R of the detection device 2R, and can detect the proximity position of the electronic pen 6 by a known electromagnetic induction method. An insulating member 72 that protects the digitizer substrate 7L from static electricity or the like is provided at the right edge, the upper left corner, and the lower left corner of the digitizer substrate 7L.

  The control board 71R and the control board 71L are connected by a harness 50. The harness 50 is a flexible board on which a pattern for electrically connecting the control board 71R and the control board 71L is formed. That is, the harness 50 is a flexible insulating film in which a plurality of conductive paths are formed. The terminal portion 51A (see FIG. 5) on one end side of the harness 50 is connected to the connector portion 73R of the control board 71R, and the terminal portion 52A (see FIG. 5) on the other end side is connected to the connector portion 73L of the control board 71L. Details of the harness 50 will be described later.

  As described above, the left cover portion 4L (see FIG. 1) holds the detection device 2L so as to be slidable in the left-right direction. The right cover portion 4R (see FIG. 1) fixes the detection device 2R. That is, the exterior cover 4 holds the detection device 2L so as to be movable in a direction toward and away from the detection device 2R in the opened state (second form). The slider 60 that connects the control board 71R and the control board 71L is configured as follows to make the detection device 2L movable with respect to the detection device 2R. The slider 60 includes a main body portion 61 and two flange portions 65. The main body 61 has a box shape that is long in the left-right direction. Two protrusions (not shown) that protrude rearward are formed on the rear surface of the main body 61. As described above, the two protrusions engage with the two eyelet holes 43 formed in the left cover portion 4L, respectively. The two flange portions 65 protrude above and below the main body portion 61, respectively.

  The rear cover 9L includes an opening 91 that penetrates in the front-rear direction below the center in the up-down direction and to the right of the center in the left-right direction. The opening 91 has a substantially rectangular shape that is long in the left-right direction. The rear cover 9 </ b> L has a recess 96 formed around the opening 91 on the front surface. The main body 61 of the slider 60 is disposed in the opening 91. The main body 61 is restricted from moving in the vertical direction by the upper end and the lower end of the opening 91. The concave portion 96 engages with the flange portion 65 of the slider 60 and supports the slider 60 so as to be slidable in the left-right direction. When the main body 61 is disposed in the opening 91, the rear surface of the flange portion 65 contacts the front surface of the recess 96, and the front surface of the flange portion 65 contacts the rear surface of the digitizer substrate 7L. The slider 60 is movable in the left-right direction by the difference in length between the main body 61 and the opening 91.

  As described above, the harness 50 is a flexible substrate in which a plurality of energization patterns are formed on a flexible insulating film. As shown in FIG. 5, the harness 50 has a thickness in the second direction and extends in the first direction with the third direction as the width direction. In the second form of the information input device 1 (see FIG. 7), the harness 50 has the first direction along the left-right direction, the second direction along the front-rear direction, and the third direction along the up-down direction. Arranged. Moreover, in the 1st form (refer FIG. 8) of the information input device 1, the harness 50 is folded by making the one side surface of a 2nd direction into an inner surface side. In the following description, for convenience, the surface on the one side in the second direction of the harness 50 (the upper surface in FIG. 5) is the surface 50A of the harness 50, and the surface on the other side in the second direction (the lower surface in FIG. 5). Will be described as the back surface 50B. The harness 50 includes a right connection part 51, a left connection part 52, and an intermediate part 53.

  The right connection part 51 includes a terminal part 51 </ b> A provided at an end part on the other side in the first direction of the harness 50. The right connection part 51 is a part extending from the terminal part 51A to one side in the first direction. The terminal portion 51 </ b> A is formed so that the width (length) in the third direction is smaller than the portion of the right connection portion 51 on one side in the first direction. The terminal portion 51A is inserted and connected to the connector portion 73R (see FIG. 4) of the control board 71R from the left side. On the back surface 50 </ b> B of the right connection portion 51, an auxiliary plate 51 </ b> B formed in accordance with the shape of the right connection portion 51 is attached. The auxiliary plate 51B increases the rigidity of the terminal portion 51A. When the terminal portion 51A is inserted into the connector portion 73R, the auxiliary plate 51B prevents a force other than the insertion direction from being applied to the terminal portion 51A. Therefore, the terminal portion 51A is less likely to cause poor contact with the connector portion 73R.

  The left connection part 52 includes a terminal part 52 </ b> A provided at one end of the harness 50 in the first direction. The left connection part 52 is a part extending from the terminal part 52A to the other side in the first direction. The left connection part 52 is located on one side in the first direction of the right connection part 51. The terminal portion 52 </ b> A has a smaller width (length) in the third direction than the portion on the other side in the first direction in the left connection portion 52. The terminal portion 52A is inserted and connected to the connector portion 73L of the control board 71L from the right side. An auxiliary plate 52B similar to the above is also attached to the back surface 50B of the left connection portion 52. The terminal portion 52A is enhanced in rigidity by the auxiliary plate 52B. Therefore, since the terminal portion 52A is protected from being applied with force other than the insertion direction by the auxiliary plate 52B when inserted into the connector portion 73L, poor contact with the connector portion 73R is unlikely to occur.

  The intermediate part 53 is a part extending in the first direction between the right connection part 51 and the left connection part 52. The intermediate unit 53 electrically connects the detection device 2R and the detection device 2L. In the intermediate portion 53, a plurality of bending portions 53A and a plurality of bending portions 53B are alternately formed in the first direction. The shape of the bending portion 53A is a shape that protrudes to one side in the second direction, that is, the surface 50A side in a cross section orthogonal to the third direction (hereinafter, also simply referred to as “third direction cross section”), and is folded back while being curved. is there. The shape of the bending portion 53B is a shape that protrudes toward the other side in the second direction, that is, the back surface 50B side in the third direction cross section, and turns back while being bent. The shape of the cross section in the third direction of the intermediate portion 53 is a wave shape, for example, a sine wave shape having an amplitude in the front-rear direction and propagating in the left-right direction. The contour line of the intermediate portion 53 in the cross section in the third direction constantly changes in the tangential direction in the curved portions 53A and 53B. That is, each of the bending portions 53A and 53B is curved in an arc shape without a crease.

  The intermediate portion 53 can be expanded and contracted in the first direction by changing the curvature of the outline in the cross section in the third direction in the curved portions 53A and 53B. In other words, in the intermediate portion 53, the opening angle of the inner peripheral surface of the curved portion 53A, that is, the back surface 50B changes, and the distance between the two curved portions 53B and 53B connected to both ends is separated and close. Can expand and contract in the first direction. Similarly, in the intermediate portion 53, the opening angle of the inner peripheral surface of the bending portion 53B, that is, the surface 50A changes, and the distance between the two bending portions 53A and 53A connected to both ends is separated and close. Can expand and contract in the first direction. In the following description, for the sake of convenience, the bending portions 53A and 53B are the states where the curvature of the bending portions 53A and 53B in the third direction cross section is small, that is, the opening angle of the inner peripheral surface of the bending portions 53A and 53B is large. Is said to be open. Further, for the sake of convenience, the curved portions 53A and 53B are closed when the curvature of the curved portions 53A and 53B in the third direction cross section is large, that is, when the opening angle of the inner peripheral surface of the curved portions 53A and 53B is small. It is called a state.

  The intermediate portion 53 can fold the harness 50 with the surface 50A on the inner surface side when the bending portion 53A is in an open state and the bending portion 53B is in a closed state. Similarly, in the intermediate portion 53, the bending portion 53A is in a closed state and the bending portion 53B is in an open state, so that the harness 50 can be folded with the surface 50A on the outer surface side.

  The harness 50 having such a shape can be manufactured as follows. As shown in FIG. 6, a mold 80 in which an upper mold 81 and a lower mold 82 are paired is produced. In the upper mold 81, convex portions 81A and concave portions 81B extending in the third direction are formed alternately. The convex portion 81A protrudes to the other side in the second direction in the cross section in the third direction, and the outer peripheral surface of the tip portion is curved in an arc shape. The concave portion 81B is formed to be concaved on one side in the second direction between the two convex portions 81A, and the inner peripheral surface is curved in an arc shape in the cross section in the third direction. The lower mold 82 is also alternately formed with convex portions 82A and concave portions 82B extending in the third direction. The convex portion 82A protrudes to the second direction one side in the cross section in the third direction, and the outer peripheral surface of the tip end portion is curved in an arc shape. The recess 82B is formed to be recessed in the second direction on the other side between the two protrusions 82A, and the inner peripheral surface is curved in an arc shape in the cross section in the third direction. When the upper die 81 and the lower die 82 are engaged, the convex portion 81A engages with the concave portion 82B, and the concave portion 81B engages with the convex portion 82A. The mold 80 is pressed with the harness 50 sandwiched between the upper mold 81 and the lower mold 82. A curved portion 53B is formed at a portion sandwiched between the convex portion 81A and the concave portion 82B. A curved portion 53A is formed in a portion sandwiched between the concave portion 81B and the convex portion 82A. The arc shape of the bending portions 53A and 53B is maintained even after the harness 50 is removed from the upper mold 81 and the lower mold 82.

  When it is desired to increase the difference between the length when the intermediate portion 53 is extended and the length when the intermediate portion 53 is contracted in the first direction, an insulating film having a smaller thickness may be employed when the harness 50 is manufactured. As the insulating film is thinner, the curvature of the third direction cross section in the state where the curved portions 53A and 53B are closed can be further increased. In addition, the length of the harness 50 in the first direction before the bending portions 53A and 53B are formed is longer than the distance when the connector portion 73L and the connector portion 73R are farthest along the path where the harness 50 is disposed. Set a longer time. For example, when the information input device 1 is in the first form, the connector portion 73L and the connector portion 73R are disposed farthest along the path in which the harness 50 is disposed.

  The information input device 1 is assembled by connecting the detection devices 2L and 2R with the harness 50 as follows. The terminal portion 52A of the left connection portion 52 of the harness 50 is inserted into the connector portion 73L of the detection device 2L from the right side while being protected by the auxiliary plate 52B. The convex portion (not shown) of the slider 60 is engaged with the eyelet hole 43 of the left cover portion 4L, and the detection device 2L is attached to the exterior cover 4. The terminal portion 51A of the right connection portion 51 is passed through the gap (see FIG. 7) between the belt-like body 44 and the front surface of the bent portion 4C, and is pulled out to the right cover portion 4R side. The terminal portion 51A is inserted from the left side into the connector portion 73R of the detection device 2R in a state protected by the auxiliary plate 51B. The rear surface 26R is bonded to the fixing sheet 41R of the right cover portion 4R, and the detection device 2R is attached to the exterior cover 4. The harness 50 is disposed between the belt-like body 44 and the bent portion 4 </ b> C, and does not protrude forward from the notebook 5.

  As described above, the information input apparatus 1 can change the arrangement form of the detection surface 21L and the detection apparatus 2R into the first form, the second form, and the third form by opening and closing the exterior cover 4. As shown in FIG. 9, in the third embodiment, the detection surface 21L (see FIG. 1) of the detection device 2L and the detection surface 21R (see FIG. 1) of the detection device 2R are arranged away from each other in the front-rear direction. The Therefore, it may be difficult for the information input device 1 to be in the third form while holding the notebook 5 as in the first form or the second form. In such a case, for example, the information input apparatus 1 may be in the third form after once removing the left cover 5L of the notebook 5 from the positioning unit 23L. The notebook 5 can be returned to the state of being attached to the information input device 1 by reattaching the left cover 5L to the positioning portion 23L after the information input device 1 is in the third form. Further, the information input device 1 can be easily used in the third embodiment, for example, when a non-booklet recording medium such as a report sheet instead of the notebook 5 is attached to only one of the detection device 2R and the detection device 2L. It is possible to become. Alternatively, for example, even when the notebook 5 is attached to the information input device 1 in a state where only the right cover 5R is fixed to the detection device 2R and the left cover 5L is not fixed, the information input device 1 can easily It can be in three forms.

  As shown in FIG. 7, in the second form of the information input device 1, the harness 50 is between the connector portion 73L of the detection device 2L arranged on the left side and the connector portion 73R of the detection device 2R arranged on the right side. Wired with. The intermediate portion 53 of the harness 50 extends rightward and rearward from the left connector portion 73L, extends rightward within the gap between the strip 44 and the bent portion 4C, and toward the right connector portion 73R. Are disposed along a path extending rightward and forward. In the second embodiment, the length F12 in which the intermediate portion 53 extends is slightly longer than the distance between the connector portion 73L and the connector portion 73R in the left-right direction. The intermediate portion 53 is stretched slightly longer than the length when the harness 50 is manufactured. The intermediate portion 53 is in a state where it can be further extended. The curved portions 53A and 53B each maintain an arc shape.

  As shown in FIG. 8, in the first form of the information input device 1, the harness 50 is wired between the connector portion 73L and the connector portion 73R disposed on the rear side of the connector portion 73L. The intermediate portion 53 of the harness 50 extends from the front connector portion 73L toward the left, and is folded back along a curved shape protruding leftward in the gap between the strip 44 and the bent portion 4C. It arrange | positions along the path | route extended rightward toward the connector part 73R of the rear side. The harness 50 is folded with the surface 50A of the intermediate portion 53 facing the inner surface, and the surface 50A of the right connection portion 51 and the surface 50A of the left connection portion 52 are arranged to face each other. The length F11 in which the intermediate part 53 extends in the first form is longer than the length F12 of the intermediate part 53 in the second form. That is, the intermediate part 53 is arranged in a state of being extended more than the second form. The curved portions 53A and 53B are in an open state. The length of the intermediate portion 53 before forming the curved portions 53A and 53B is set longer than the length F11. Therefore, in the first embodiment, the curved portions 53A and 53B each maintain an arc shape.

  As shown in FIG. 9, in the third form of the information input device 1, the harness 50 is wired between the connector portion 73L and the connector portion 73R disposed on the front side of the connector portion 73L. The intermediate portion 53 of the harness 50 extends leftward from the front connector portion 73R, and is folded back along a curved shape protruding leftward in the gap between the belt-like body 44 and the bent portion 4C. It arrange | positions along the path | route extended rightward toward the connector part 73L of the rear side. The harness 50 is folded with the back surface 50B in the intermediate portion 53 facing the inner surface, and the back surface 50B in the right connection portion 51 and the back surface 50B in the left connection portion 52 are arranged to face each other. The length F13 in which the intermediate portion 53 extends in the third embodiment is shorter than the length F12 of the intermediate portion 53 in the second embodiment. That is, the intermediate part 53 is arranged in a contracted state as compared with the second form. The curved portions 53A and 53B are closed. The folds are not formed in the bending portions 53A and 53B, and the bending portions 53A and 53B maintain the arc shape even in the third form, that is, even when the intermediate portion 53 is contracted.

  The length in the second direction of the curved portions 53A and 53B in the third embodiment is E1. The length E1 is, for example, the first between the position of the protruding tip or inflection point of the bending portion 53A and the position of the protruding tip or inflection point of the bending portion 53B connected to the bending portion 53A in the third direction cross section. It is the length in two directions. The length E1 is smaller than the length D in the second direction of the gap between the strip 44 and the bent portion 4C in the third embodiment. When contracted, that is, the length E1 in the second direction of the curved portions 53A, 53B in the third configuration is longer than the length in the second direction of the curved portions 53A, 53B in the first configuration and the second configuration. That is, the intermediate portion 53 of the harness 50 is set such that the size of the curved portions 53A and 53B is within the gap between the belt-like body 44 and the bent portion 4C when contracted. Therefore, the harness 50 is not easily compressed in the gap between the belt-like body 44 and the bent portion 4C and is not easily subjected to a load.

  Thus, in the case of the second configuration, the intermediate portion 53 of the harness 50 is expanded smaller than the expanded state of the first configuration, and is expanded more than the contracted state of the third configuration. Therefore, the load concerning the harness 50 in a 2nd form is smaller than the load concerning the harness 50 in a 1st form and a 3rd form, and is close to a no-load state. The first form of the information input device 1 is a form during transportation or storage. For this reason, information input device 1 is often made into the 1st form rather than the 2nd form and the 3rd form. That is, the harness 50 is often in a state where a larger load is applied than in the case of the second embodiment. As described above, in the first embodiment, the length of the intermediate portion 53 is set so that the curved portions 53A and 53B maintain the circular arc shape, so that the information input device 1 applies a load on the harness 50. Can be reduced.

  Then, by providing the harness 50 and the slider 60 configured as described above, the information input device 1 can move the detection device 2L in a direction toward or away from the detection device 2R. When the user attaches the notebook 5 to the information input device 1, the user inserts the left cover 5L of the notebook 5 from the right side of the holding sheet 41L and arranges it on the positioning portion 23L of the detection device 2L. The left cover 5L of the notebook 5 is fixed to the positioning portion 23L by the adhesive portion 22L. Next, the user places the right cover 5R of the notebook 5 on the positioning unit 23R of the detection device 2R. At this time, the user can move the detection device 2L in the left-right direction together with the note 5. Since the left cover 5L is first fixed to the detection device 2L, the movement range of the note 5 is restricted. However, in the information input device 1, as described above, the degree of freedom in positioning the detection device 2L with respect to the detection device 2R is ensured. Therefore, the user can easily arrange the right cover 5R of the notebook 5 on the positioning portion 23R. The attachment of the notebook 5 is completed by fixing the right cover 5R of the notebook 5 to the positioning section 23R by the bonding section 22R.

  As described above, in the first embodiment, the left cover portion 4L and the right cover portion 4R that respectively hold the detection device 2L and the detection device 2R move the detection device 2L and the detection device 2R relatively to detect each other. The device 2L and the detection device 2R can be brought close to and away from each other. Therefore, when the note 5 is opened and closed, the detection device 2L and the detection device 2R can move relatively in accordance with the positions of the left cover 5L and the right cover 5R of the note 5, respectively. The information input device 1 can prevent the notebook 5 from being bent without placing a load on the notebook 5 in alignment with the notebook 5.

  The harness 50 can follow the change in the positional relationship between the detection device 2L and the detection device 2R accompanying the bending of the bent portion 4C by expanding and contracting. Therefore, the harness 50 can maintain the electrical connection between the detection device 2L and the detection device 2R even if the detection device 2L and the detection device 2R move relatively.

  In addition, the harness 50 expands and contracts by an operation in which the curvatures of the curved portions 53A and 53B change and the opening angle widens or narrows. Even if the notebook 5 is repeatedly opened and closed, and the distance between the detection device 2L and the detection device 2R is repeatedly changed, the harness 50 can be expanded and contracted reliably. Therefore, the electrical connection between the detection device 2L and the detection device 2R Connection can be maintained. Further, since the harness 50 is expanded and contracted by the change in curvature of the bending portions 53A and 53B, the harness 50 can reduce the load applied to the deformation of the bending portions 53A and 53B, and can improve the durability.

  In the second direction, the size of the curved portions 53A and 53B during contraction is equal to or smaller than the size of the gap between the belt-like body 44 and the bent portion 4C. Therefore, even when the bending portions 53A and 53B are bent by contraction, the harness 50 is more easily expanded and contracted because it is not easily caught by the bent portion 4C and the strip 44.

  Further, in the third direction cross section, the curved portions 53A and 53B maintain an arc shape even when contracted. Therefore, even if the harness 50 is in a state where the bending portions 53A and 53B are bent by contraction, the load related to the inflection point is dispersed, so that the durability can be improved.

  The information input device 1 can be easily carried by arranging the detection device 2L and the detection device 2R in the first form and sandwiching the notebook 5 between the detection device 2L and the detection device 2R. Moreover, the information input device 1 arrange | positions the detection apparatus 2L and the detection apparatus 2R to a 2nd form, can expose the writing surface of the notebook 5, and can make it write to a user. Furthermore, the information input device 1 arranges the detection device 2L and the detection device 2R in the third form, thereby exposing the writing surface of the notebook 5 while the detection device 2L and the detection device 2R are folded. Can be written. In the transition to each form, the plurality of bending portions 53A and 53B each change the curvature, whereby the harness 50 expands and contracts and can follow the change in the positional relationship between the detection device 2L and the detection device 2R. Therefore, the harness 50 can maintain the electrical connection between the detection device 2L and the detection device 2R.

  Next, a second embodiment of the present invention will be described with reference to FIGS. The configuration of the information input device 101 (see FIG. 11) according to the second embodiment is different from the first embodiment in the configuration of the harness 150, and the other parts are the same as those in the first embodiment. Therefore, hereinafter, the configuration of the harness 150 will be described, and description of other parts will be simplified or omitted.

  A harness 150 shown in FIG. 10 is a flexible substrate in which a plurality of energization patterns are formed on a flexible insulating film, as in the first embodiment. The harness 150 has a thickness in the second direction and extends in the first direction with the third direction as the width direction. The harness 150 includes a right side connection part 151, a left side connection part 152, and an intermediate part 153.

  The right side connection portion 151 includes a terminal portion 151A provided at the end portion on the other side in the first direction of the harness 150, and is a portion extending from the terminal portion 151A to the one side in the first direction. In the right connection portion 151, the width (length) in the third direction of the terminal portion 151A is smaller than the width in other portions. The terminal portion 151A is inserted and connected to the connector portion 73R (see FIG. 4) from the left side. An auxiliary plate 151B similar to that of the first embodiment is attached to the back surface 150B of the right connection portion 151, and the rigidity of the terminal portion 151A is increased.

  The left connection part 152 includes a terminal part 152A provided at one end of the harness 150 in the first direction and extends from the terminal part 152A to the other side in the first direction. The left connection portion 152 also has a width (length) in the third direction in the terminal portion 152A smaller than the width in other portions. The terminal portion 152A is inserted and connected to the connector portion 73L (see FIG. 4) from the right side. An auxiliary plate 152B is also attached to the back surface 150B of the left connection portion 152, and the rigidity of the terminal portion 152A is increased.

  The intermediate part 153 extends in the first direction between the right connection part 151 and the left connection part 152, and is a part that electrically connects the detection device 2R and the detection device 2L. In the intermediate portion 153, a plurality of bent portions 153A and a plurality of bent portions 153B are alternately formed in the first direction. The bent portion 153A is a portion formed by, for example, folding the intermediate portion 153 with the surface 150A side as a mountain fold along a virtual line extending in the third direction on the surface 150A. Similarly, the bent portion 153B is a portion that is formed by bending the intermediate portion 153 with the surface 150A side valley-folded along a virtual line extending in the third direction on the surface 150A, for example. The bent portion 153A protrudes to the one side in the second direction, that is, the surface 150A side in the cross section in the third direction. The bent portion 153B projects to the other side in the second direction, that is, the back surface 150B side in the cross section in the third direction. That is, the shape of the cross section in the third direction of the intermediate portion 153 is also wavy, for example, a triangular wave shape having amplitude in the front-rear direction and propagating in the left-right direction.

  The intermediate portion 153 can expand and contract in a bellows shape by bending the bent portions 153A and 153B along the creases provided at the distal ends of the bent portions 153A and 153B, respectively. That is, in the intermediate portion 153, the opening angle of the inner peripheral surface of the bent portion 153A, that is, the back surface 150B is changed, and the distance between the two bent portions 153B and 153B connected to both ends is separated and close to each other. Can expand and contract in the first direction. Similarly, the opening angle of the inner peripheral surface of the bent portion 153B, that is, the surface 150A, of the intermediate portion 153 changes, and the distance between the two bent portions 153A and 153A connected to both ends is separated and close to each other. Can expand and contract in the first direction. In the following description, a state in which the opening angle of the inner peripheral surface of the bent portions 153A and 153B in the third direction cross section is referred to as a state in which the bent portions 153A and 153B are opened for convenience. Further, a state in which the opening angle of the inner peripheral surface of the bent portions 153A and 153B in the cross section in the third direction is reduced is referred to as a state in which the bent portions 153A and 153B are closed.

  The intermediate portion 153 can fold the harness 150 with the surface 150A on the inner surface side when the bent portion 153A is opened and the bent portion 153B is closed. Similarly, in the intermediate portion 153, the bent portion 153A is in a closed state and the bent portion 153B is in an open state, so that the harness 150 can be folded with the surface 150A as the outer surface side. What is necessary is just to produce the harness 150 of such a shape using the metal mold | die (not shown) similar to 1st embodiment. When it is desired to increase the difference between the length when the intermediate portion 153 is stretched and the length when the intermediate portion 153 is contracted in the first direction, an insulating film having a smaller thickness may be employed when the harness 150 is manufactured. As the thickness of the insulating film is smaller, the opening angle of the inner peripheral surface can be made smaller in the state where the bent portions 153A and 153B are closed. In addition, the length of the harness 150 in the first direction before the formation of the bent portions 153A and 153B is longer than the distance when the connector portion 73L and the connector portion 73R are farthest along the path in which the harness 150 is disposed. Set a longer time. In the manufacturing process of the information input device 101, the harness 150 is assembled between the belt-like body 44 and the bent portion 4 </ b> C by being assembled in the same process as in the first embodiment, and jumps forward from the notebook 5. Absent.

  As shown in FIG. 11, in the second form of the information input device 101, the harness 150 is between the connector portion 73L of the detection device 2L arranged on the left side and the connector portion 73R of the detection device 2R arranged on the right side. Wired with. In the second embodiment, the intermediate portion 153 of the harness 150 is disposed along the same path as that of the first embodiment. In the second embodiment, the length F22 in which the intermediate portion 153 extends is slightly longer than the distance between the connector portion 73L and the connector portion 73R in the left-right direction. The intermediate portion 153 is extended slightly longer than the length when the harness 150 is manufactured. The intermediate portion 153 is in a state where it can be further expanded. The bent portions 153A and 153B maintain the bent state at the fold line.

  As shown in FIG. 12, in the first form of the information input device 101, the harness 150 is wired between the connector portion 73L and the connector portion 73R disposed on the rear side of the connector portion 73L. Also in the first embodiment, the intermediate portion 153 of the harness 150 is disposed along the same path as that in the first embodiment. The harness 150 is folded with the surface 150A of the intermediate portion 153 facing the inner surface, and the surface 150A of the right connection portion 151 and the surface 150A of the left connection portion 152 are arranged to face each other. The length F21 in which the intermediate part 153 extends in the first form is longer than the length F22 of the intermediate part 153 in the second form. That is, the intermediate part 153 is arranged in an extended state than the second form. The bent portions 153A and 153B are in an open state. The length of the intermediate portion 153 before forming the bent portions 153A and 153B is set to be longer than the length F21. Therefore, in the first embodiment, the bent portions 153A and 153B are not fully extended, and maintain the bent state at the fold.

  As shown in FIG. 13, in the third form of the information input device 101, the harness 150 is wired between the connector portion 73L and the connector portion 73R disposed on the front side of the connector portion 73L. In the third embodiment, the intermediate portion 153 of the harness 150 is disposed along the same path as that of the first embodiment. The harness 150 is folded with the back surface 150B of the intermediate portion 153 facing the inner surface, and the back surface 150B of the right connection portion 151 and the back surface 150B of the left connection portion 152 are arranged to face each other. The length F23 in which the intermediate portion 153 extends in the third embodiment is shorter than the length F22 of the intermediate portion 153 in the second embodiment. That is, the intermediate part 153 is arranged in a contracted state as compared with the second form. The bent portions 153A and 153B are closed. The bent portions 153A and 153B are regularly bent along the fold line.

  The length in the second direction of the bent portions 153A and 153B in the third embodiment is E2. The length E2 is, for example, the length in the second direction between the tip of the bent portion 153A in the third direction cross section, that is, the position of the fold, and the tip of the bent portion 153B connected to the bent portion 153A, that is, the position of the fold. is there. The length E2 is smaller than the length D in the second direction of the gap between the strip 44 and the bent portion 4C in the third embodiment. When contracted, that is, the length E2 in the second direction of the bent portions 153A, 153B in the third configuration is longer than the length in the second direction of the bent portions 153A, 153B in the first configuration and the second configuration. In other words, the intermediate portion 153 of the harness 150 is set such that the size of the bent portions 153A and 153B is within the gap between the belt-like body 44 and the bent portion 4C when contracted. Therefore, the harness 150 is not easily compressed in the gap between the belt-like body 44 and the bent portion 4C, and is not easily subjected to a load.

  Thus, in the case of the second configuration, the intermediate portion 153 of the harness 150 is expanded smaller than the expanded state of the first configuration, and is expanded more than the contracted state of the third configuration. Therefore, the load concerning the harness 150 in a 2nd form is smaller than the load concerning the harness 150 in a 1st form and a 3rd form, and is close to a no-load state. In addition, the information input device 101 is often in the first form rather than the second form and the third form. That is, the harness 150 is often in a state where a larger load is applied than in the case of the second embodiment. Since each of the bent portions 153A and 153B is regularly bent with the fold as a boundary, the bent portions 153A and 153B can stably expand and contract during expansion and contraction. Since the harness 150 can be regularly bent at the bent portions 153A and 153B, even if the harness 150 is maintained in an extended state, the load applied to the harness 150 is distributed between the bent portions 153A and 153B and reduced. Can do.

  As described above, in the second embodiment, the harness 150 expands and contracts by an operation in which the angle inside the bent portions 153A and 153B changes and expands or narrows. The bent portions 153A and 153B bend regularly along the crease. Therefore, the harness 150 can expand and contract stably. Even if the notebook 5 is repeatedly opened and closed, and the distance between the detection device 2L and the detection device 2R is repeatedly changed, the harness 150 can be expanded and contracted reliably, so that the electrical connection between the detection device 2L and the detection device 2R Connection can be maintained.

  The information input device 101 can be easily carried by arranging the detection device 2L and the detection device 2R in the first form and sandwiching the notebook 5 between the detection device 2L and the detection device 2R. Moreover, the information input device 101 can expose the writing surface of the notebook 5 and allow the user to write by arranging the detection device 2L and the detection device 2R in the second form. Furthermore, the information input device 101 arranges the detection device 2L and the detection device 2R in the third form, thereby exposing the writing surface of the notebook 5 while the detection device 2L and the detection device 2R are folded. Can be written. In the deformation to each form, the plurality of bent portions 153A and 153B are regularly bent, so that the harness 150 expands and contracts and can follow the change in the positional relationship between the detection device 2L and the detection device 2R. Therefore, the harness 150 can maintain the electrical connection between the detection device 2L and the detection device 2R.

  In the second direction, the size of the bent portions 153A and 153B during contraction is equal to or smaller than the size of the gap between the bent portion 4C and the belt-like body 44. Therefore, even when the bent portions 153A and 153B are bent due to contraction, the harness 150 can be more reliably expanded and contracted because it is not easily caught by the bent portion 4C and the belt-like body 44.

  Next, a third embodiment of the present invention will be described with reference to FIGS. The configuration of the information input device 201 (see FIG. 15) according to the third embodiment is different from the first embodiment and the second embodiment in the configurations of the harness 250 and the rubber connectors 273L and 273R. It is the same structure as embodiment and 2nd embodiment. Therefore, hereinafter, the configurations of the harness 250 and the rubber connectors 273L and 273R will be described, and descriptions of other parts will be simplified or omitted.

  The material of the harness 250 shown in FIG. 14 is blended with an insulating silicon rubber, for example, a conductive material such as carbon, silver powder, gold-plated silica, graphite, conductive zinc white, etc. to maintain elasticity. So-called conductive silicon rubber that exhibits conductivity as it is is used. The harness 250 can be made of conductive synthetic rubber instead of conductive silicon rubber. Conductive silicone rubber is superior in conductivity, heat resistance / cold resistance, and durability to conductive synthetic rubber.

  The harness 250 has a thickness in the second direction, and extends in the first direction with the third direction as the width direction. The harness 250 includes a conducting portion 254, a first insulating portion 255, and second insulating portions 256 and 257. The conduction part 254 is a part that extends in a rod shape in the first direction and is formed of conductive silicon rubber. For example, four conduction parts are formed. The first insulating portion 255 is a portion that is the same length as the conducting portion 254 and extends in the first direction and is formed of insulating silicon rubber. For example, five first insulating portions 255 are formed. The conducting portions 254 and the first insulating portions 255 are alternately arranged in the third direction and arranged in close contact. First insulating portions 255 are disposed at both ends in the third direction. The conductive portion 254 and the first insulating portion 255 are bonded to each other by an adhesive, for example. That is, the four conductive portions 254 are maintained in a non-contact state by the first insulating portion 255.

  The second insulating portions 256 and 257 are portions that extend in a plate shape in the first direction and are formed of insulating silicon rubber. The length of the second insulating portions 256 and 257 in the third direction is substantially the same as the length in which the conducting portion 254 and the first insulating portion 255 are disposed in close contact with each other. The lengths of the second insulating portions 256 and 257 in the first direction are shorter than the lengths of the conducting portion 254 and the first insulating portion 255 in the first direction. The second insulating portion 256 is bonded to an intermediate portion of the conductive portion 254 and the first insulating portion 255 on one side in the second direction excluding both ends in the first direction, for example, with an adhesive. The second insulating portion 257 is bonded to an intermediate portion excluding both ends in the first direction on the other side in the second direction of the conducting portion 254 and the first insulating portion 255, for example, with an adhesive. That is, the periphery of the four conductive portions 254 is covered by the first insulating portion 255 and the second insulating portions 256 and 257 so as not to contact the outside except for the exposed portions at both ends.

  The harness 250 includes a right side connection part 251, a left side connection part 252, and an intermediate part 253. The right connection portion 251 is a portion where the conducting portion 254 and the first insulating portion 255 are exposed on the other side in the first direction of the second insulating portions 256 and 257. The right side connection part 251 is inserted and connected from the left side to a rubber connector 273R (see FIG. 15) provided on a control board (not shown) of the detection device 2R. The rubber connector 273R and the right connection portion 251 are kept connected by frictional force. The frictional force between the rubber connector 273R and the right connection portion 251 is larger than the elastic force of the harness 250. Therefore, even if the harness 250 expands and contracts, the right connection portion 251 does not come out of the rubber connector 273R.

  The left side connection portion 252 is a portion where the conducting portion 254 and the first insulating portion 255 are exposed on one side in the first direction of the second insulating portions 256 and 257. The left side connection part 252 is inserted and connected from the right to a rubber connector 273L (see FIG. 15) provided on a control board (not shown) of the detection device 2L. The connection state of the rubber connector 273L and the left connection portion 252 is also maintained by the frictional force. The frictional force between the rubber connector 273L and the left connection portion 252 is larger than the elastic force of the harness 250. Therefore, even if the harness 250 expands and contracts, the left connection portion 252 does not come out of the rubber connector 273L.

  The intermediate portion 253 is a portion where the second insulating portions 256 and 257 are provided. The intermediate part 253 extends in the first direction between the right connection part 251 and the left connection part 252, and electrically connects the detection device 2R and the detection device 2L.

  The harness 250 having such a configuration can be expanded and contracted by being elastic with silicon rubber. Further, the harness 250 can be folded with the front surface 250A or the back surface 250B being the inner surface side. In the manufacturing process of the information input device 201, the harness 250 is assembled between the belt-like body 44 and the bent portion 4 </ b> C by being assembled in the same process as in the first embodiment, and jumps forward from the notebook 5. Absent.

  As shown in FIG. 15, in the second form of the information input device 201, the harness 250 is between the rubber connector 273L of the detection device 2L arranged on the left side and the rubber connector 273R of the detection device 2R arranged on the right side. Wired with. In the second embodiment, the intermediate portion 253 of the harness 250 is disposed along the same path as in the first embodiment and the second embodiment. In the second embodiment, the length F32 in which the intermediate part 253 extends is slightly longer than the distance between the rubber connector 273L and the rubber connector 273R in the left-right direction. For example, the intermediate portion 253 is elongated longer than the natural length, that is, the length in the most contracted state. The intermediate portion 253 is in a state where it can be further expanded. In the second embodiment, the length F32 of the intermediate portion 253 may be a natural length.

  As shown in FIG. 16, in the first form of the information input device 201, the harness 250 is wired between the rubber connector 273L and the rubber connector 273R disposed on the rear side of the rubber connector 273L. Also in the first embodiment, the intermediate portion 253 of the harness 250 is disposed along the same path as in the first embodiment and the second embodiment. The harness 250 is folded with the surface 250A in the intermediate portion 253 facing the inner surface, and the surface 250A in the right connection portion 251 and the surface 250A in the left connection portion 252 are arranged to face each other. The length F31 in which the intermediate part 253 extends in the first form is longer than the length F32 of the intermediate part 253 in the second form. That is, the intermediate part 253 is arranged in a state of being extended more than the second form. The length F31 of the intermediate part 253 in the first embodiment is longer than the natural length.

  As shown in FIG. 17, in the third form of the information input device 201, the harness 250 is wired between the rubber connector 273L and the rubber connector 273R disposed on the front side of the rubber connector 273L. In the third embodiment, the intermediate portion 253 of the harness 250 is disposed along the same path as in the first embodiment and the second embodiment. The harness 250 is folded with the back surface 250B of the intermediate portion 253 facing the inner surface, and the back surface 250B of the right side connection portion 251 and the back surface 250B of the left side connection portion 252 are arranged to face each other. In the third embodiment, the length of the path in which the intermediate portion 253 is disposed is shorter than the length of the path in which the intermediate portion 253 is disposed in the second embodiment. Therefore, the length F33 in which the intermediate portion 253 extends in the third embodiment is equal to or shorter than the length F32 of the intermediate portion 253 in the second embodiment. In the second embodiment, if the intermediate portion 253 is in an expanded state, for example, in the third embodiment, the intermediate portion 253 is arranged in a contracted state than in the second embodiment. If the length F32 of the intermediate part 253 in the second form is a natural length, for example, the length F33 of the intermediate part 253 in the third form is also a natural length. In addition, length F33 of the intermediate part 253 in a 3rd form may be longer than natural length, and may be natural length. When the length of the path in which the intermediate part 253 is arranged is shorter than the natural length, the intermediate part 253 has a natural length F33 and is arranged in the path in a relaxed state. When the length of the path in which the intermediate part 253 is arranged is longer than the natural length, the intermediate part 253 has a length that is longer than the natural length F33, and is arranged in the path in a tensioned state.

  As described above, the harness 250 can be stretched in accordance with the form of the information input device 201 by having an elastic force. The information input device 201 is often set to the first form rather than the second form and the third form. However, since the harness 250 can be smoothly expanded and contracted by the elastic force of the forming material, the state in which the detection device 2L and the detection device 2R are electrically connected can be reliably maintained.

  As described above, in the third embodiment, the harness 250 expands and contracts in accordance with the change in the distance between the detection device 2L and the detection device 2R that occurs as the notebook 5 opens and closes due to the elasticity of the rubber member.

However, a support portion for the slider 60 may be provided on the rear surface of the rear cover 9L. In this case, the rear surface of the rear cover 9L and the support portion may support the slider 60 in the front-rear direction. The slider 60 and the outer cover 4 may be engaged not by using the protrusion and the eyelet hole 43 but by other methods. For example, other methods such as screws, rivets, staples, hooks, and sewing may be employed. Alternatively, the detection device 2R may include the slider 60 and move in a direction approaching and separating from the detection device 2L. Alternatively, each of the detection devices 2L and 2R may be provided with the slider 60 and move in the direction of approaching and separating from each other.

  Moreover, the structure which can be expanded-contracted in the left-right direction may be sufficient as 4 C of bending parts. In this case, the detection devices 2L and 2R may be configured to be fixed to the left cover portion 4L and the right cover portion 4R, respectively.

  In the first embodiment, the plurality of bending portions 53A and 53B are formed in the intermediate portion 53 of the harness 50. However, for example, only one bending portion 53A or one bending portion 53B is formed in the intermediate portion 53. May be. Although the bending portions 53A and the bending portions 53B are configured to alternately continue, there may be a straight portion between the bending portions 53A and the bending portions 53B where the tangential direction in the third direction cross section does not change. Moreover, although the intermediate part 53 of the harness 50 is arrange | positioned in the gap | interval of the strip | belt-shaped body 44 and the bending part 4C, there is no strip | belt-shaped body 44 and it is arrange | positioned in the state exposed to the front side of the bending part 4C in a 2nd form. Also good.

  In the second embodiment, the plurality of bent portions 153A and 153B are formed in the intermediate portion 153 of the harness 150. However, for example, only one bent portion 153A or one bent portion 153B may be formed in the intermediate portion 153. . Although the bent portions 153A and the bent portions 153B are configured to alternately continue, a portion extending in the first direction in the cross section in the third direction may be formed between the bent portions 153A and the bent portions 153B.

  Moreover, like the harness 350 shown in FIG. 18, in the intermediate part 353, curved part 353A, 353B may be formed discontinuously, ie, intermittently. For example, a connection portion 353C extending along the first direction in the cross section in the third direction may be formed in the non-formed portion of the bending portions 353A and 353B. The bending portions 353A, the bending portions 353B, and the connection portions 353C may be alternately arranged.
