  At least the central portion 4C of the exterior cover 4 is made of a flexible material. That is, at least the central portion 4C has a flexibility that can be deformed according to an external force. Examples of such materials include leather, synthetic leather, polyamide-based and urethane-based flexible materials. On the other hand, the left cover portion 4L and the right cover portion 4R do not necessarily need to be made of a flexible material. However, in the present embodiment, the entire outer cover 4 is made of a single material having flexibility. In this case, the exterior cover 4 can be easily manufactured integrally with the same material.

  A fixing sheet 41R for fixing the detection unit 2R is provided on the front surface of the right cover unit 4R. The fixed sheet 41R is fixed to the exterior cover 4 by having the upper side, the right side, and the lower side woven into the edge 45 of the exterior cover 4 and the left side woven into the central portion 4C.

  As shown in FIGS. 1 and 4, a reinforcing member 11 is attached to the central portion 4 </ b> C. The reinforcing member 11 has rigidity higher than that of at least the flexible central portion 4C. The reinforcing member 11 is made of, for example, metal or resin. In this case, the reinforcing member 11 having higher rigidity than the central portion 4C can be easily manufactured. Examples of metals that can be used include stainless steel and iron. Examples of the resin that can be used include ABS resin and fiber reinforced resin.

  The reinforcing member 11 is disposed at least at a part of the central part 4C and has a shape that prevents at least a part of the central part 4C from being deformed into a flat shape. For example, when the reinforcing member 11 is formed in a U-shape or a V-shape when viewed from the vertical direction that is the longitudinal direction of the central portion 4C (that is, the cross-sectional shape in the direction orthogonal to the longitudinal direction of the central portion 4C is U In the case of a letter shape or a V letter shape), at least a part of the central portion 4C can be prevented from being deformed into a flat shape. The “U-shape” and “V-shape” here are not limited to the exact shapes of the alphabet “U” and “V”, but include shapes close to “U” and “V”. The reinforcing member having such a shape will be described later.

  The reinforcing member 11 illustrated in the present embodiment is made of metal, and is disposed so as to correspond to substantially the entire center portion 4C as shown in FIG. More specifically, as shown in FIG. 5, the reinforcing member 11 includes a rectangular metal plate having substantially the same vertical length as that of the exterior cover 4. It is formed by bending in a semicircular shape. The cross-sectional shape of the reinforcing member 11 in the left-right direction is U-shaped (more strictly, semicircular).

  The method for attaching the reinforcing member 11 to the central portion 4C is not particularly limited, and any method may be used as long as the reinforcing member 11 does not come off the exterior cover 4. In the present embodiment, of the two curved surfaces of the reinforcing member 11, the U-shaped protruding direction side surface is attached to the front surface of the central portion 4C with an adhesive. That is, the reinforcing member 11 is attached to the central portion 4C so that the central portion 4C of the exterior cover 4 protrudes in the opposite direction (rearward) from the side where the detection device 2 is disposed. Furthermore, the upper and lower ends of the reinforcing member 11 are pressed by the edge 45 of the exterior cover 4. In addition, the central portion 4C may be formed as a bag-shaped storage portion with two sheets, for example. In this case, the reinforcing member 11 may be attached to the central portion 4C by being inserted into the storage portion. At least a part of the wiring portion 50 (intermediate portion 53) is disposed on the front side of the reinforcing member 11 along the left-right direction.

  As shown in FIGS. 1 and 2, the exterior cover 4 having such a configuration is maintained by the reinforcing member 11 in a state where the central portion 4 </ b> C is curved in a U shape (more precisely, a semicircular shape) when viewed in the vertical direction. It is. On the other hand, the left cover portion 4L and the right cover portion 4R can be bent along a boundary line with the central portion 4C extending in the vertical direction. In the present embodiment, the form of the exterior cover 4 changes as the notebook 5 attached to the detection device 2 opens and closes. The form change of the exterior cover 4 will be described later.

  With reference to FIG. 1, FIG. 2, FIG. 6 and FIG. 7, the movement of the detection device 2 and the exterior cover 4 when using the handwriting input system 1 and the change in the form of the exterior cover 4 will be described. As shown in FIG. 1, when using the handwriting input system 1, the user attaches the notebook 5 to the detection device 2 to which the exterior cover 4 is attached. At this time, the user positions the notebook 5 with respect to the detection device 2 by aligning the left cover 5L and the right cover 5R of the notebook 5 with the positioning sections 23L and 23R of the detection sections 2L and 2R, respectively. The notebook 5 is bonded and fixed to the detection device 2 by the bonding portions 22L and 22R while being positioned with respect to the detection device 2. An outer cover 4 is attached to the detection device 2. As the notebook 5 is opened and closed, the left cover portion 4L and the right cover portion 4R are extended or bent with respect to the central portion 4C. At this time, the detection unit 2L moves relative to the detection unit 2R in accordance with the movement of the left cover 5L of the notebook 5 while being held between the left cover unit 4L and the holding sheet 41L.

  As typical forms of the exterior cover 4 when the handwriting input system 1 is used, there are the following two forms. As shown in FIGS. 2 and 6, the first form is a form in which the notebook 5 is completely opened and the left cover part 4L and the right cover part 4R are arranged on the same plane. As shown in FIG. 7, the second form is a form in which the notebook 5 is completely closed, and the front surface of the left cover portion 4 </ b> L and the front surface of the right cover portion 4 </ b> R are opposed to each other with the notebook 5 and the detection device 2 interposed therebetween. is there. FIG. 1 shows the form of the exterior cover 4 in the middle of opening and closing of the notebook 5, that is, the form of the exterior cover 4 in the middle of changing between the first form and the second form.

  In the change between the first form and the second form, in the second form (see FIG. 7) when the notebook 5 is completely closed, the detection units 2L and 2R (more specifically, the connector part 73L). , 73R) is the maximum length required for wiring. Therefore, as described above, in the present embodiment, the length of the wiring portion 50 is set based on this maximum length.

  As a result, as shown in FIG. 6, when the outer cover 4 takes the first form, the intermediate part 53 of the wiring part 50 is slack compared to when the outer cover 4 takes the second form. At this time, the reinforcing member 11 prevents the portion of the central portion 4C where the reinforcing member 11 is mounted from being deformed into a flat shape. The reinforcing member 11 can maintain the slack portion of the intermediate portion 53 in a slack state in a space secured inside the U-shape. Therefore, even when the user applies an external force in the direction from the detection device 2 toward the exterior cover 4 when entering information in the notebook 5, the reinforcing member 11 has the slackened wiring portion 50 bent inconveniently. The possibility of breakage can be reduced.

  A change may be suitably added to the said embodiment. For example, the material, size, shape, and the like of the reinforcing member 11 provided on the exterior cover 4 can be changed as appropriate. As described above, the reinforcing member 11 may be attached to at least a part of the central portion 4C and have higher rigidity than the central portion 4C. And what is necessary is just to have a shape which prevents at least one part among center part 4C deform | transforming into planar shape. For example, the reinforcing member 11 may be formed of a resin having a rigidity and higher than that of the central portion 4C without changing the size and shape thereof. Below, with reference to FIGS. 8-14, the reinforcement members 12-18 which concern on another modification are demonstrated. Similar to the reinforcing member 11, these reinforcing members 12 to 18 can also reduce the possibility of damage to the wiring portion 50.

  The reinforcing member 12 shown in FIG. 8 is produced by processing one metal plate, similarly to the reinforcing member 11 (see FIG. 5) exemplified in the above embodiment. The reinforcing member 12 has substantially the same size and shape as the reinforcing member 11. However, the reinforcing member 12 is different from the reinforcing member 11 in that the reinforcing member 12 has a pair of notches 121 and 122 not provided in the reinforcing member 11. The notches 121 and 122 are provided at positions facing the left and right direction. The positions of the notches 121 and 122 are positions through which the wiring portion 50 passes when the exterior cover 4 is attached to the detection device 2. The wiring part 50 is arrange | positioned along the left-right direction so that the inside of the notches 121 and 122 may be passed. Therefore, compared with the reinforcing member 11 having no notch, it is more preferable in that the wiring portion 50 is in strong contact with the edge of the reinforcing member 12 and the possibility of damage to the wiring can be reduced.

  The reinforcing member 13 shown in FIG. 9 is formed of a resin having higher rigidity than the central portion 4C. The reinforcing member 13 has substantially the same size and shape as the reinforcing member 11 shown in FIG. However, the reinforcing member 13 is different from the reinforcing member 11 in that the reinforcing member 13 includes a plurality of ribs 130 that connect gaps in the left-right direction generated by being formed in a U shape when viewed in the vertical direction. Although the rigidity is higher than that of the central portion 4C, the resin has a lower rigidity than the metal. Therefore, by providing the rib 130 inside the curved surface, it is possible to increase the strength when the reinforcing member 13 attached to the exterior cover 4 receives an external force from the detection device 2 side toward the exterior cover 4 side. More preferable. The rib 130 is preferably provided at a position different from the position through which the wiring portion 50 passes when the exterior cover 4 is attached to the detection device 2. The number of ribs 130 shown in FIG. 9 is merely an example, and an appropriate number may be provided according to the size of the reinforcing member 13 and the characteristics of the resin that is the material.

  The reinforcing member 14 shown in FIG. 10 has a pair of notches 141 and 142 provided at positions facing in the left-right direction, like the reinforcing member 12 shown in FIG. Is also made of a highly rigid resin. Therefore, the reinforcing member 14 also includes a plurality of ribs 140 arranged in the left-right direction inside the curved surface, like the reinforcing member 13 shown in FIG. The function of the ribs 140 and the number of the ribs 140 are not limited in the same manner as the ribs 130 of the reinforcing member 13. The positions of the notches 141 and 142 are positions through which the wiring portion 50 passes when the exterior cover 4 is attached to the detection device 2. The rib 140 is provided at a position different from the notches 141 and 142 in the vertical direction. The wiring part 50 is arrange | positioned along the left-right direction so that the inside of the notches 141 and 142 may be passed. Therefore, it is more preferable than the reinforcing member 13 having no notch in that the wiring portion 50 is in strong contact with the edge of the reinforcing member 14 and the possibility of damage to the wiring can be reduced.

  The reinforcing member 15 shown in FIG. 11 is made of metal, and the contour shape and size thereof are the same as the contour shape and size of the reinforcing member 12 shown in FIG. However, the reinforcing member 12 is formed of a single metal plate, whereas the reinforcing member 15 is formed of a frame 150 having a plurality of holes. The thickness of the frame 150 may be set according to the characteristics of the metal used as the material. In addition, the reinforcing member 15 has a pair of notches 151 and 152 provided at positions facing in the left-right direction, like the reinforcing member 12. The reinforcing member 15 has the same function as the reinforcing member 12. Note that a similar frame-shaped reinforcing member may be formed of resin as long as sufficient rigidity can be ensured. Further, the reinforcing member 15 is not necessarily provided with the notches 151 and 152.

  The reinforcing member 16 shown in FIG. 12 corresponds to the vicinity of the notches 121 and 122 in the reinforcing member 12 shown in FIG. That is, the reinforcing member 16 does not have a size corresponding to the entire central portion 4C (see FIG. 4), and is attached to a part of the central portion 4C in the vertical direction. More specifically, in the reinforcing member 16, the notches 161 and 162 provided at positions facing in the left-right direction are in positions where the wiring portion 50 passes when the exterior cover 4 is attached to the detection device 2. As just described, it may be attached to the central portion 4C. Since the reinforcing member 16 can prevent at least a portion of the central portion 4C where the wiring portion 50 is disposed from being deformed on a plane, the wiring portion 50 may be damaged like the reinforcing members 11 to 15 described above. Can be reduced.

  Note that all the reinforcing members 11 to 16 illustrated above are semicircular when viewed from the vertical direction that is the longitudinal direction of the central portion 4C (that is, the cross-sectional shape in the horizontal direction that is the direction orthogonal to the longitudinal direction of the central portion 4C). Is formed in a semicircle). All of the reinforcing members 11 to 16 may be changed to a U-shape other than a semicircular shape in the shape seen from the vertical direction (cross-sectional shape in the left-right direction). For example, all of the reinforcing members 11 to 16 may be changed from a vertical shape (cross-sectional shape in the left-right direction) to a strict U-shape or an arc shape that is not a semicircle. As in the reinforcing member 17 shown in FIG. 13, the shape viewed from the top and bottom (the cross-sectional shape in the left and right direction) may be a U-shape with no rounded corners (a shape without one side of a rectangle or trapezoid). In all of the reinforcing members 11 to 16, the shape seen from the vertical direction (the cross-sectional shape in the left-right direction) may be changed to a V-shape, like the reinforcing member 18 shown in FIG.

  The exterior cover 4 exemplified in the above embodiment is provided with the reinforcing member 11 at the central portion 4C, so that the central portion 4C protrudes in the opposite direction (rearward) from the side where the detection device 2 is disposed. When the user writes information in the notebook 5 using the handwriting input system 1, there is a possibility that the user places the exterior cover 4 on a plane such as a desk with the rear surface facing downward. In this case, since the central portion 4C to which the reinforcing member 11 is mounted protrudes downward, the left end of the left cover portion 4L and the right end of the right cover portion 4R are disposed below the connecting portion between the central portion 4C and each. Is done. That is, the left cover portion 4L and the right cover portion 4R are inclined downward toward the left end and the right end, respectively. Therefore, the writing surface of the paper of the note 5 is similarly inclined, so that it may be difficult for the user to fill in the note 5.

  Therefore, as shown in FIG. 15, an exterior cover 40 may be configured. In addition, in FIG. 15, illustration of the detection apparatus 2 and the exterior cover 40 is simplified. The exterior cover 40 has substantially the same configuration as the exterior cover 4, but differs from the exterior cover 4 in that a part of the left cover part 4L and a part of the right cover part 4R include a pair of protruding parts 4D. The pair of projecting portions 4D are arranged when portions different from the projecting portions 4D of the left cover portion 4L and the right cover portion 4R are arranged on the same plane (that is, when the exterior cover 40 takes the second form). .., Approximately the same amount (height H shown in FIG. 15) protrudes in the direction perpendicular to the plane. At this time, the reinforcing member 11 protrudes at least a part of the central portion 4C in the same direction by substantially the same amount (height H) as the pair of protruding portions 4D. The protruding portion 4D can be used in any way as long as the portions of the left cover portion 4L and the right cover portion 4R that are different from the protruding portion 4D are arranged on the same plane, and protrude substantially the same amount in the direction orthogonal to the plane. It may be formed.

  For example, as shown in FIG. 15, a pair of protrusions 4D may be formed by attaching a pair of protrusion members 9 to the left cover part 4L and the right cover part 4R. Although the material of the protrusion member 19 is not specifically limited, Like the reinforcement member 11, it is preferable that it has rigidity higher than the flexible center part 4C. For example, the protruding member 19 may be made of metal or resin. The material of the protruding member 19 may be the same as or different from the material of the reinforcing member 11. The shape of the protruding member 19 is not particularly limited. For example, each protruding member 19 may be formed in a bar shape that is slightly shorter than the vertical length of the exterior cover 40. The protruding member 19 may be fixed in a state where it is wound inside the edge portion 45 along the left end of the left cover portion 4L and the edge portion 45 along the right end of the right cover portion 4R. In addition, for example, the left end portion of the left cover portion 4L and the right end portion of the right cover portion 4R are folded back and fixed in the opposite direction (rearward) from where the detection device 2 is disposed, so that A pair of protrusions 4D may be formed by the portions. A pair of protrusions 4 </ b> D may be formed by a member different from the exterior cover 4 by sticking the protrusion members to the rear surface of the left cover portion 4 </ b> L and the rear surface of the right cover portion 4 </ b> R.

  According to the exterior cover 40 having such a configuration, when the exterior cover 4 is placed on a plane such as a desk with the rear surface facing downward, the left cover portion 4L and the right cover are formed by the reinforcing member 11 and the pair of projecting portions 4D. The portions of the portion 4R that are different from the protruding portion 4D are each maintained in a substantially horizontal posture. Thereby, the attitude | position of the detection apparatus 2 is stabilized. Further, since the writing surface of the paper of the notebook 5 is also kept substantially horizontal, the user can easily enter information in the notebook 5.

  The protrusions 4D attached to the left cover part 4L and the right cover part 4R do not necessarily have the same shape and size as in the example shown in FIG. The positions where the protrusions 4D are provided in the left cover portion 4L and the right cover portion 4R are not necessarily the left end or the right end. The mounting method of the protruding member 19 on the left cover portion 4L and the right cover portion 4R may be another method such as adhesion in addition to the above example. In addition, not only the reinforcement member 11, but any of the reinforcement members 12-18 which concern on the modification mentioned above, and protrusion part 4D may be combined.

  Further, the target for which the exterior covers 4 and 40 are used is not limited to the detection device 2 of the handwriting input system 1. The exterior covers 4 and 40 are applicable to other information terminals having wirings that connect a plurality of electronic components to each other. For example, the exterior covers 4 and 40 may be applied to an information terminal in which a main body including a control unit and an operation unit and a display unit separate from the main body are connected by a wiring unit. In this case, the user may attach the main body and the display unit to the right cover unit 4R and the left cover unit 4L, respectively, with at least a part of the wiring unit extending in the left-right direction. Also in this case, as in the case of the detection device 2 described above, even if the outer covers 4 and 40 are folded left and right, the wiring portion is bent undesirably by one of the reinforcing members 11 to 18 attached to the central portion 4C. The possibility of breakage can be reduced.

  The shape of the exterior cover 4 is not limited to the rectangular shape exemplified in the embodiment. It is obvious that the information terminal to which the exterior cover 4 is attached can be appropriately changed according to the shapes of the portions arranged in the left cover portion 4L and the right cover portion 4R. Moreover, the part to which any of the reinforcing members 11 to 18 is attached does not need to be at the center position in one direction of the exterior cover 4, and the position may be changed according to the shape of the information terminal.

  The configuration in which the detection units 2L and 2R are held so as to be relatively movable with each other is not limited to the example of the exterior cover 4 described above. For example, like an exterior cover disclosed in Japanese Patent Application Laid-Open No. 2014-99116 (see US Patent Application Publication No. 2014/132533), the three sides other than the upper side are sealed and are not bent. It may be a rectangular bag that is long in the left-right direction. In this case, any one of the reinforcing members 11 to 18 may be attached to one lateral center portion of the two-layer sheets forming the bag body inside the exterior cover. The detection device 2 is inserted from the upper-side accommodation opening, and is arranged so that at least a part of the wiring part 50 extends in the left-right direction at the center part, and the detection parts 2L and 2R are located on the left side and the right side inside the exterior cover. What is necessary is just to be accommodated in a part. In this case, the detection units 2L and 2R are both held by the exterior cover in a state that they can move inside the exterior cover.

  In the above embodiment and its modifications, the exterior covers 4 and 40 are examples of the “information terminal cover” of the present invention. The central portion 4C, the left cover portion 4L, and the right cover portion 4R are examples of the “first portion”, “second portion”, and “third portion” of the present invention, respectively. Each of the reinforcing members 11 to 18 is an example of the “reinforcing member” of the present invention. The notches 121 and 122, the notches 141 and 142, the notches 151 and 152, and the notches 161 and 162 are examples of “a pair of notches”. The protrusion 4D is an example of the “pair of protrusions” in the present invention. The detection device 2 is an example of the “information terminal” in the present invention. The detection units 2L and 2R are examples of the “pair of sensors” in the present invention. The wiring unit 50 is an example of the “wiring unit” in the present invention.
