Description

  The present invention relates to a raised sheet and an input device.

  Conventionally, input devices such as a capacitive touch panel, a touch pad, and a touch switch using a touch sensing technology are known. The touch panel is an input device that is attached to the display surface of a bank terminal (cash dispenser), ticket vending machine, personal computer, OA device, electronic notebook, PDA, mobile phone, etc. The coordinates are detected. A touchpad is an input device mounted on a notebook computer, for example. The capacitance of the capacitor, which is composed of a flat sensor and a human finger, on the sensor surface varies slightly. The finger trajectory traced on the surface of the sensor is associated with the movement of the mouse pointer of the personal computer monitor. The touch switch is an input device used as an operation switch for an elevator or an illumination device, for example, and a capacitance change of a capacitor composed of a metal detection panel provided on the switch and a human finger. , And the detection result is output as a change in voltage.

  Conventionally, such an input device has been configured to detect direct contact (touch input) with a human finger or the like, but in recent years, it is not touch input with a finger or the like, but a touch panel surface or a touch pad surface. An input device (an input device capable of hovering input) that detects a proximity state of a finger or the like to the surface of the touch switch is being developed (for example, Patent Document 1).

JP2013-80290A

  However, an input device capable of hovering input can detect an input operation by a user in a state where there is no direct finger contact with the input device, that is, with the finger etc. floating on the input device. For this reason, there is a problem that the user cannot obtain an operational feeling with respect to the input device, and is confused as to how close a finger or the like should be when operating the input device.

  In addition, an apparatus / equipment equipped with an input device capable of hovering input can be configured to perform different operations depending on the distance between the input device and a finger or the like. For example, when a touch panel is used as an input device, when a finger or the like approaches a predetermined distance with respect to the input device surface (touch panel surface), the proximity position coordinates on the input device (touch panel) can be detected. In addition, it is configured to detect an input signal when a finger or the like is brought close to the input device surface (touch panel surface), so that not only the position of the two-dimensional finger or the like is sensed but also the approach direction (third) of the finger or the like. It is possible to configure such that the movement of a finger or the like in the direction of the axis of () can also be sensed. Even in the case of such an input device capable of three-dimensional input, as described above, since the operation is performed with a finger or the like floating on the input device, the user has a feeling of operation with respect to the input device. In order to input a two-dimensional finger position (finger coordinate position) to the input device or to move the finger or the like in the approaching direction (third axis direction) of the input device. There is a problem that it is difficult to grasp the sense of distance from the input device for allowing the user to input.

  Hereinafter, the raising sheet | seat and input device concerning the actual condition form of this invention are demonstrated. First, a first embodiment of a raised sheet 1a and an input device 2a according to the present invention will be described with reference to the accompanying drawings. The raised sheet 1a according to the first embodiment can be suitably used for a capacitive touch sensor such as a touch pad or a touch switch to which the touch sensing technology is applied. 2 is a raised sheet 1a that is used by being disposed on the surface of the touch electrode portion 31 in the capacitive touch sensor 3a. Further, the input device 2a according to the first embodiment is configured by arranging the raised sheet 1a according to the first embodiment so as to overlap the surface of the touch sensor 3a. The raised sheet 1 a includes a sheet-like sheet main body 11 and a plurality of flexible raised protrusions 12 standing on one surface of the sheet main body 11. The raised sheet 1a is arranged so that the other surface of the sheet main body 11 (the surface on which the raised protrusions 12 are not formed) overlaps the surface of the touch electrode portion 31 provided in the touch sensor 3a. In each drawing, in order to facilitate the understanding of the configuration, it is partially enlarged or reduced rather than the actual size ratio.

  Here, examples of the touch sensor 3a on which the raised sheet 1a is disposed include a touch pad and a touch switch as described above. As this touch sensor 3a, a capacitive touch sensor capable of hovering input can be suitably used. Specifically, a change in capacitance is detected when a finger or the like is lifted from the surface of the touch sensor 3a, that is, when the distance between the finger or the like and the surface of the touch sensor 3a reaches a predetermined distance. Thus, a touch sensor that can output an operation signal can be preferably used. Further, when a finger or the like approaches the surface of the touch sensor 3a at a predetermined distance, the first operation signal can be output, and when the finger or the like is further brought closer to the surface side of the touch sensor 3a. The second operation signal can be detected based on the change in capacitance so that not only the position of the finger as a point but also the movement of the finger in the approaching direction of the finger can be detected. The touch sensor configured as described above can also be suitably used.

  As described above, the raised sheet 1a includes the sheet main body 11 and the raised protrusions 12 formed on the sheet main body 11. The sheet body 11 is preferably formed of a dielectric material. Specifically, polyethylene terephthalate (PET), polyimide (PI), polyethylene naphthalate (PEN), polyethersulfone (PES), polyetherether. Ketone (PEEK), polycarbonate (PC), polypropylene (PP), polyamide (PA), polyacryl (PAC), acrylic, amorphous polyolefin resin, cyclic polyolefin resin, aliphatic cyclic polyolefin, norbornene thermoplastic Examples thereof include a flexible film such as a resin and a laminate of two or more of these. The sheet body 11 may be formed using either a transparent or opaque material. For example, when the sheet body 11 is formed of a transparent material, a light source disposed below the touch sensor 3a is illuminated. Since the light is transmitted through the sheet body 11, the user can clearly recognize the location of the touch sensor 3a. In addition, when a finger or the like is brought close to the touch sensor 3a, a light source or the like disposed under the touch sensor 3a is configured to emit light, and feedback to the user that an operation on the touch sensor 3a has been performed. It becomes possible.

  The raised protrusions 12 are protrusions that are arranged so as to stand on one surface of the sheet main body 11 and bend when pressed with a finger or the like, and are restored to the original shape when the pressure is released. It is formed to have elasticity as much as possible. Such raised protrusions 12 are preferably formed of a dielectric material. Specifically, for example, polyethylene terephthalate (PET), polyimide (PI), polyethylene naphthalate (PEN), polyethersulfone ( PES), polyetheretherketone (PEEK), polycarbonate (PC), polypropylene (PP), polyamide (PA), polyacrylic (PAC), acrylic, amorphous polyolefin resin, cyclic polyolefin resin, aliphatic cyclic polyolefin Further, it is preferably formed from a material such as a norbornene-based thermoplastic resin. In addition, a fluorine-based thermoplastic resin such as perfluoroalkoxy fluorine resin (PFA) can be used. When the raised protrusions 12 are formed of a fluorine-based resin, the slipping property at the time of contact is good, and dirt is difficult to adhere.

  The raised protrusions 12 can be formed as various types of protrusions, as shown in the enlarged cross-sectional views of the main parts in FIGS. The raised protrusions 12 shown in FIG. 3A have a substantially cylindrical shape, and the raised protrusions 12 shown in FIG. 3B have a substantially conical shape. Further, the raised protrusions 12 shown in FIG. 3C have a ring shape (loop pile shape). The raised protrusions 12 are not limited to the forms shown in FIGS. 3A to 3C, but are bent when pressed with a finger or the like, and can be restored to their original shapes when the pressing is released. Any protrusion may be used as long as it has elasticity. The height of the raised protrusions 12 can be set to about 0.5 mm to 10 mm, for example. Further, the maximum diameter of the raised protrusions 12 can be set to about 50 μm to 1.0 mm. In addition, what is necessary is just to adjust the density of the raising protrusion 12 suitably according to the feeling of the touch at the time of the contact to the raising protrusion 12.

  The raised protrusions 12 are arranged, for example, by planting hair on one surface of the sheet main body 11. When flocking, a flocking device used in brush production or the like can be used. Further, for example, after a thread formed from the above-described predetermined material is sewn at a predetermined interval so as to cover the entire surface of the sheet main body 11, sandpaper, sandcloth, sandnet, sandroll, brush, and needle cloth The nap-like protrusions 12 may be formed by performing napping treatment using a method such as the above. Alternatively, the raised protrusions 12 may be formed by forming a fibrous sheet such as a non-woven fabric from the above-described predetermined material and subjecting the fibrous sheet to a raising treatment. In addition, when raising the hair-like projection 12 by raising the fiber sheet, the fibrous sheet itself on which the raised-like projection 12 stands is equivalent to the sheet body 11.

  The raised sheet 1a is adhered via an adhesive layer so that the other surface of the sheet main body 11 (the surface on which the raised protrusions 12 are not formed) overlaps the surface of the touch electrode portion 31. For the pressure-sensitive adhesive layer, for example, a general adhesive or pressure-sensitive adhesive such as an epoxy-based resin or an acrylic-based resin can be used, and may include a core material made of a norbornene-based resin film. Moreover, an adhesive layer may be formed by overlapping a plurality of sheet-like adhesive materials, and a plurality of different sheet-like adhesive materials may be formed in an overlapping manner. Moreover, in order to peel the raised sheet 1a from the touch electrode part 31 and to be able to replace it, the adhesive layer may be configured as a removable adhesive layer rich in peelability.

  The height (length) of each raised protrusion 12 may be formed to be uniform, or a plurality of raised protrusions 12 formed on the sheet body 11 have at least two different protrusion heights. You may comprise so that it may become an aggregate | assembly of the kind of protrusion. For example, as shown in the cross-sectional view of FIG. 4A and the plan view of FIG. 4B (the plan view seen from the direction of arrow A in FIG. 4A), You may comprise so that the raised protrusion 12a to stand and the raised protrusion 12b to stand in the sheet | seat inner side part enclosed by the sheet | seat peripheral part may differ in height. In FIG. 4, the height of the raised protrusions 12b standing on the inner side of the sheet is configured to be higher than the height of the raised protrusions 12a standing on the peripheral edge of the sheet. Further, as shown in the cross-sectional view of FIG. 5, at least two kinds of protrusions having different protrusion heights may be randomly mixed on the sheet main body 11.

  For example, in order to distinguish between the plurality of raised protrusions 12a erected on the sheet peripheral portion and the plurality of raised protrusions 12b erected on the inner side of the sheet, a plurality of raised shapes erected on the sheet peripheral portion. You may comprise so that the processus | protrusion 12a and the several raised-like processus | protrusion 12b standingly arranged in a sheet | seat inner side may each become a different color.

  Since the raised sheet 1a according to the first embodiment of the present invention is configured to include a plurality of flexible raised protrusions 12 standing on one surface of the sheet main body 11, as described above. When the raised sheet 1a is used by being arranged on the surface of the touch electrode portion 31 in the touch sensor 3a capable of hovering input, the user performs an operation while touching the raised protrusion 12. That is, it is possible to operate the touch sensor while obtaining a feeling (operation feeling) of touching the raised protrusions 12. Further, the presence of the raised protrusions 12 allows the user to easily grasp how close the finger or the like should be to the touch sensor 3a, and can easily operate the touch sensor 3a. It becomes possible.

  Further, the touch sensor 3a is configured such that a first operation signal can be output when a finger or the like approaches the surface of the touch sensor 3a at a predetermined distance, and the finger or the like is further touched with the touch sensor 3a. The second operation signal at the time of approaching the surface side of the screen is configured to be detected based on the change in capacitance, and not only the position of the finger as a point but also the approach direction of the finger etc. When adopting a configuration that can sense the movement of a finger or the like, according to the raised sheet 1a according to the first embodiment of the present invention, an operation when the tip of the raised protrusion 12 is lightly touched with a finger or the like. And it becomes possible to make a user recognize easily the difference in operation of at least 2 steps | paragraphs, such as operation at the time of pushing in on the raising protrusion 12.

  When the plurality of raised protrusions 12 provided on the sheet main body 11 are configured as an aggregate of at least two kinds of protrusions having different protrusion heights, the user recognizes a change in the feeling of pressing against the raised protrusions 12. It becomes possible to make it. In such a configuration, it becomes possible to give the user a feeling of operation when pushing into the raised protrusions 12 with a finger or the like, and as described above, the tip of the raised protrusion 12 is lightly touched with a finger or the like. For a user who uses a touch sensor that can perform at least two steps of operation, such as the operation at the time of pressing and the operation when pushed into the raised protrusion 12, it becomes possible to further enhance the operation feeling. It is possible to easily recognize whether the operation performed is a contact operation with respect to the raised protrusions 12 or a pressing operation. Further, in the case where the height of the raised protrusions 12b erected on the inner side of the sheet is higher than the height of the raised protrusions 12a erected on the peripheral edge of the sheet, the optimum proximity to the touch sensor 3a. It is possible to clearly show the location (or the pressed location) to the user.

  Even when the plurality of raised protrusions 12a erected on the peripheral edge of the sheet and the plurality of raised protrusions 12b erected on the inner side of the sheet are configured to have different colors, the optimal proximity to the touch sensor 3a It is possible to clearly show the user (or the pressed position) to the user.

  Next, 2nd Embodiment of the raising sheet | seat and input device which concern on this invention is described with reference to an accompanying drawing. The raised sheet 1b according to the second embodiment can be suitably used for a capacitive touch panel for detecting an input position to which the touch sensing technology is applied, and is shown in a schematic cross-sectional view of FIG. Thus, it is the raising sheet | seat 1b arrange | positioned and used for the surface of the capacitive touch panel 3b. Moreover, the input device 2b according to the second embodiment is configured by arranging the raised sheet 1b according to the second embodiment so as to overlap the surface of the touch panel.

In FIG. 6, in order to facilitate the understanding of the configuration, the size is not enlarged but partially enlarged or reduced. In addition, the number of the raised protrusions 12 is reduced.

  As the touch panel 3b, a capacitive touch panel capable of hovering input can be suitably used. Specifically, a change in capacitance is detected in a state where a finger or the like is floating with respect to the surface of the touch panel 3b, that is, in a state where the distance between the finger or the like and the surface of the touch panel 3b reaches a predetermined distance. A touch panel that can calculate the coordinates of a proximity position (hovering position) of a finger or the like with respect to can be suitably used. In addition, when a finger or the like approaches the touch panel 3b surface at a predetermined distance, the proximity position coordinates on the touch panel 3b can be detected, and input when the finger or the like is further brought closer to the touch panel 3b surface side. The signal can be detected based on the change in capacitance, and not only the two-dimensional finger position is detected, but also the finger movement in the approaching direction (third axis direction) of the finger, etc. It is possible to provide a so-called three-dimensional input touch panel configured to be sensed.

  As a structure of the touch panel 3b, various touch panel structures can be employed. In the present embodiment, as shown in FIG. 6, a first planar body 32 and a second planar body 33 are provided.

An omitted touch panel 3b may be employed. Alternatively, a touch panel 3b configured by forming the touch electrode portion 31a on one surface side of the substrate 321 and forming the touch electrode portion 31b on the other surface side may be employed. Further, the second planar body 33 is omitted, and a touch panel configured by forming both the touch electrode portion 31a and the touch electrode portion 31b on one surface side of the substrate 321 of the first planar body 32 is adopted. May be. In the case of the touch panel 3b having such a configuration, a portion where the touch electrode portion 31a and the touch electrode portion 31b overlap each other is formed, and the touch electrode portion 31a is interposed by interposing an insulating portion in the overlap portion.

  The raised protrusions 12 are arranged, for example, by planting hair on one surface of the sheet main body 11. When flocking, a flocking device used in brush production or the like can be used. Further, for example, after a thread formed from the above-described predetermined material is sewn at a predetermined interval so as to cover the entire surface of the sheet main body 11, sandpaper, sandcloth, sandnet, sandroll, brush, and needle cloth The nap-like protrusions 12 may be formed by performing napping treatment using a method such as the above. Alternatively, the raised protrusions 12 may be formed by forming a fibrous sheet such as a non-woven fabric from the above-described predetermined material and subjecting the fibrous sheet to a raising treatment. In addition, when raising the hair-like projection 12 by raising the fiber sheet, the fibrous sheet itself on which the raised-like projection 12 stands is equivalent to the sheet body 11.

  The raised sheet 1 is adhered via an adhesive layer (not shown) so that the other surface of the sheet main body 11 (the surface on which the raised protrusions 12 are not formed) is superimposed on the surface of the touch panel 3b.

You may comprise so that protrusion 12d may differ in height. In FIG. 10, the height of the raised protrusions 12d erected in the region corresponding to the inner side of the electrode is configured to be higher than the height of the raised protrusions 12c erected in the region corresponding to the peripheral edge of the electrode. ing. Further, as shown in the cross-sectional view of FIG. 11, at least two types of protrusions having different protrusion heights may be randomly mixed on the sheet body 11.

  Further, for example, a plurality of raised protrusions 12c standing in a region corresponding to the electrode peripheral portion of each touch electrode portion 31a, 31b and a region corresponding to the electrode inner portion of each touch electrode portion 31a, 31b are provided. In order to distinguish the plurality of raised protrusions 12d, the raised protrusions 12c and the raised protrusions 12d may be configured to have different colors.

  Since the raised sheet 1 according to the second embodiment of the present invention is configured to include a plurality of flexible raised protrusions 12 standing on one surface of the sheet body 11 as described above. When the raised sheet 1 is placed on the surface of the touch panel capable of hovering input and used, the user performs an operation while touching the raised protrusions 12. That is, it is possible to operate the touch panel while obtaining a feeling (operation feeling) of touching the raised protrusions 12.

Even when the color of the raised protrusions 12d is different, it is possible to clearly show the user the optimum proximity location (or pressing location) with respect to the touch electrode portions 31a and 31b.

  Next, an input device 2c according to a third embodiment will be described. This input device 2c is an input device to which capacitive touch sensing technology is applied. As shown in the perspective view of FIG. 12 and the schematic configuration sectional view of FIG. 13, the input device 2c itself is configured in a raised shape. It has a different form. The input device 2c includes a base material 15 made of a dielectric material and a plurality of flexible raised protrusions 12 standing on one side of the base material.

  The substrate 15 is preferably formed of a dielectric material, and specifically, polyethylene terephthalate (PET), polyimide (PI), polyethylene naphthalate (PEN), polyethersulfone (PES), polyetherether. Ketone (PEEK), polycarbonate (PC), polypropylene (PP), polyamide (PA), polyacryl (PAC), acrylic, amorphous polyolefin resin, cyclic polyolefin resin, aliphatic cyclic polyolefin, norbornene thermoplastic Examples thereof include a flexible film such as a resin and a laminate of two or more of these. The base material 15 may be formed using either a transparent or opaque material. However, when the base material 15 is formed using a transparent material, for example, an illuminating body is separately disposed below the input device 2c, and By allowing the light emitted from the illuminating body to pass through the base material 15, the user can clearly recognize the location of the input device 2c. In addition, by configuring the illuminator to emit light when a finger or the like is brought into contact with the input device 2c, it is possible to provide feedback to the user that an operation has been performed on the input device 2c.

  Each raised protrusion 12 is a protrusion that is arranged so as to stand on one surface of the base material 15 so that it is bent when pressed with a finger or the like, and is restored to its original shape when the pressure is released. It is formed so as to have elasticity that can be restored. As shown in FIG. 13, the raised protrusion 12 includes a core body 121 formed of a conductive material and a cover body 122 formed of a dielectric material that covers the surface of the core body 121. . Further, each raised protrusion 12 adjacent to each other is configured such that the cores 121 are electrically connected to each other by a conductive member 123. It should be noted that all the raised protrusions 12 adjacent to each other may be configured such that the cores 121 are electrically connected to each other by the conductive member 123, or the raised protrusions 12 adjacent to each other. For some of them, the cores 121 may be electrically connected by the conductive member 123.

  Examples of the conductive material forming the core body 121 include metal materials such as copper, silver, tin, aluminum, nickel, and chromium, metal oxide materials, and the like. Moreover, a composite material in which ultrafine conductive carbon fibers such as carbon nanotubes, carbon nanohorns, carbon nanowires, carbon nanofibers, and graphite fibrils, or ultrafine conductive fibers made of a silver material are dispersed in a polymer material that functions as a binder can be exemplified. . Here, a conductive polymer such as polyaniline, polypyrrole, polyacetylene, polythiophene, polyphenylene vinylene, polyphenylene sulfide, poly p-phenylene, polyheterocyclic vinylene, PEDOT: poly (3,4-ethylenedioxythiophene) should be adopted as the polymer material. Can do. In addition, polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyethersulfone (PES), polyetheretherketone (PEEK), polycarbonate (PC), polypropylene (PP), polyamide (PA), acrylic, polyimide, Non-conductive polymers such as epoxy resins, phenol resins, aliphatic cyclic polyolefins, norbornene-based thermoplastic resins can be employed.

  Examples of the dielectric material that covers the surface of the core 121 include, for example, polyethylene terephthalate (PET), polyimide (PI), polyethylene naphthalate (PEN), polyethersulfone (PES), polyetheretherketone (PEEK), Materials such as polycarbonate (PC), polypropylene (PP), polyamide (PA), polyacryl (PAC), acrylic, amorphous polyolefin resin, cyclic polyolefin resin, aliphatic cyclic polyolefin, norbornene thermoplastic resin, etc. Can be mentioned. In addition, a fluorine-based thermoplastic resin such as perfluoroalkoxy fluorine resin (PFA) can be used. When a fluororesin is used as a dielectric material for covering the surface of the core body 121, the slipperiness at the time of contact with the raised protrusions 12 is good, and dirt is difficult to adhere.

  The raised protrusions 12 can be formed as protrusions of various forms, as shown in the enlarged cross-sectional views of the main parts in FIGS. The raised protrusions 12 shown in FIG. 14A have a substantially cylindrical shape, and the raised protrusions 12 shown in FIG. 14B have a substantially conical shape. Further, the raised protrusion 12 shown in FIG. 14C has a ring shape. The raised protrusions 12 are not limited to the forms described in FIGS. 14A to 14C, but are bent when pressed with a finger or the like, and restored to the original shape when the press is released. Any protrusion may be used as long as it has elasticity. The height of the raised protrusions 12 can be set to about 0.5 mm to 10 mm, for example. Further, the maximum diameter of the raised protrusions 12 can be set to about 50 μm to 1.0 mm. In addition, what is necessary is just to adjust the density of the raising protrusion 12 suitably according to the feeling of the touch at the time of the contact to the raising protrusion 12.

  The raised protrusions 12 are arranged, for example, by planting hair on one surface of the base material 15. When flocking, a flocking device used in brush production or the like can be used. Further, for example, a thread-like body in which the surface of a long linear body formed of a conductive material is covered with a dielectric material is sewn at a predetermined interval so as to cover the entire surface of the base material 15 and then sanded. The raised protrusions 12 may be formed by raising treatment using paper, sand cloth, sand net, sand roll, brush, needle cloth or the like. Alternatively, a fiber sheet such as a nonwoven fabric is formed from a fiber material in which the surface of a linear body formed of a conductive material is covered with a dielectric material, and the fiber sheet is subjected to a raising process, thereby raising the nap. The protrusion 12 may be formed. In addition, when raising the hair-like projection 12 by raising the fiber sheet, the fiber sheet itself on which the raised-like projection 12 stands is equivalent to the base material 15.

  In addition, as described above, at least a part of each of the raised protrusions 12 adjacent to each other is configured such that the cores 121 are electrically connected to each other by the conductive member 123. As the conductive member 123 to be connected, a conductive thread-like member can be exemplified. It is preferable that the conductive member 123 electrically connects the base ends of the cores 121 (the base-side ends of the cores 121). Further, instead of connecting the cores 121 to each other with the conductive thread-like member, for example, as shown in FIG. 15, a conductive film (conductive member 123) is formed on one surface of the base material 15 in advance. In addition, it may be configured such that the cores 121 are electrically connected to each other by planting the raised protrusions 12 exposing the cores 121 on the base end side on the film. The conductive member 123 that connects the cores 121 to each other detects a change in capacitance when a user's finger or the like comes into contact with the raised protrusion 12 and is based on the change in capacitance. An external circuit 50 for generating an output signal is electrically connected as shown in FIGS. For example, when the input device 2c having such a configuration is used as an operation switch of a lighting apparatus, the input device 2c detects contact with the raised protrusions 12 based on a change in capacitance, and illuminates the contact signal (output signal). It can be used as a signal for ON / OFF control of the device.

  In addition, the external circuit 50 not only detects the change in capacitance when it comes into contact with the raised protrusions 12, but also when a finger or the like is pushed into the raised protrusions 12 (the finger or the like is further brought closer to the substrate 15 side). It may be configured to detect a change in capacitance (when it is applied). In the case of such a configuration, for example, when the input device 2c is used as an operation switch of the lighting apparatus, contact with the raised protrusion 12 is detected based on a change in capacitance, and the contact signal (output signal) Is used as a signal for ON / OFF control of the lighting device, and the brightness of the lighting device is controlled using a signal detected based on a change in capacitance when a finger or the like is pushed into the raised protrusion 12. Can be used as a signal.

  The height (length) of each raised projection 12 may be formed to be uniform, or the plurality of raised projections 12 may be an aggregate of at least two types of projections having different projection heights. You may comprise so that it may become. For example, as shown in the cross-sectional view of FIG. 16A or the plan view of FIG. 16B (the plan view seen from the direction of arrow C in FIG. 16A), it stands on the periphery of the base material 15. You may comprise so that the raising protrusion 12e to provide and the raising protrusion 12f standingly arranged in the inner part enclosed by a peripheral part may differ in height. In FIG. 16, it is configured such that the height of the raised protrusions 12f erected on the inner side surrounded by the peripheral edge portion is higher than the height of the raised protrusions 12e erected on the peripheral edge portion. Further, as shown in the cross-sectional view of FIG. 17, at least two types of protrusions having different protrusion heights may be mixed on the base material 15 at random.

  Further, for example, in order to distinguish between the raised protrusions 12e erected on the peripheral edge of the substrate 15 and the raised protrusions 12f erected on the inner side surrounded by the peripheral edge, The raised protrusions 12e provided and the raised protrusions 12f provided upright on the inner side may have different colors.

  In the input device 2c according to the third embodiment having such a configuration, when a finger or the like touches (or approaches) the raised protrusion 12, the core body 121 and the core body 121 made of a conductive material in the raised protrusion 12 are provided. The structure composed of the conductive members 123 that electrically connect each other is grounded via the capacitance of the human body, and the external circuit 50 detects the value of the current flowing through the structure at that time. It is detected that the person has touched the input device 2c, and the contact signal can be used as, for example, an ON / OFF control signal of the lighting device.

  Moreover, since the input device 2c according to the third embodiment includes the raised protrusions 12 formed in a raised shape, the user can obtain a feeling of touching the raised protrusions 12 (operation feeling). The input device 2c can be operated.

  Further, not only the detection of the change in capacitance when contacting the raised protrusions 12, but also when a finger or the like is pushed into the raised protrusion 12 (when the finger or the like is further brought closer to the substrate 15 side). By configuring the external circuit 50 so that a change in capacitance can be detected, an operation when the tip of the raised protrusion 12 is lightly touched with a finger or the like, and an operation when pushed into the raised protrusion 12 are used. Thus, it is possible to obtain the input device 2c that allows the user to easily recognize the difference in operation in at least two stages.

  Further, when the plurality of raised protrusions 12 are configured as an aggregate of at least two kinds of protrusions having different protrusion heights, it becomes possible for the user to recognize a change in pressing feeling against the raised protrusions 12. In such a configuration, it becomes possible to give the user a feeling of operation when pushing into the raised protrusions 12 with a finger or the like, and as described above, the tip of the raised protrusion 12 is lightly touched with a finger or the like. For the user who uses the input device 2c capable of performing at least two steps of operation such as the operation at the time of pressing and the operation when pushed into the raised protrusion 12, it becomes possible to further enhance the operational feeling. It is possible to easily recognize whether the operation performed is a contact operation on the raised protrusion 12 or a pressing operation.

  When a plurality of raised protrusions 12 are configured as an aggregate of at least two types of protrusions having different protrusion heights, when a finger or the like is pushed into the raised protrusions 12, many raised protrusions 12 Etc. will come into contact. As a result, when the finger or the like is pushed in, the capacitance changes greatly. By detecting this large change in capacitance, whether the user's operation is a contact operation with respect to the raised protrusions 12 is pushed in. It becomes possible for the input device 2c to easily determine whether the pressing operation is performed. In the case where the height of the plurality of raised protrusions 12f erected on the inner side of the substrate 15 is higher than the height of the raised protrusions 12e erected on the peripheral edge of the substrate 15. Thus, it is possible to clearly indicate to the user the optimum pressing position for the input device 2c.

  In addition, when the raised protrusions 12e standing on the peripheral edge of the base material 15 and the raised protrusions 12f standing on the inner side surrounded by the peripheral edge are configured in different colors, the optimum push against the input device 2c is also possible. It is possible to clearly show the location to the user.

Moreover, a composite material in which ultrafine conductive carbon fibers such as carbon nanotubes, carbon nanohorns, carbon nanowires, carbon nanofibers, and graphite fibrils, or ultrafine conductive fibers made of a silver material are dispersed in a polymer material that functions as a binder can be exemplified. . Here, a conductive polymer such as polyaniline, polypyrrole, polyacetylene, polythiophene, polyphenylene vinylene, polyphenylene sulfide, poly p-phenylene, polyheterocyclic vinylene, PEDOT: poly (3,4-ethylenedioxythiophene) should be adopted as the polymer material.

In addition, a fluorine-based thermoplastic resin such as perfluoroalkoxy fluorine resin (PFA) can be used. When a fluororesin is used as a dielectric material for covering the surface of the core body 121, the slipperiness at the time of contact with the raised protrusions 12 is good, and dirt is difficult to adhere.

  The insulating raised protrusions 13 and the raised protrusions 12 can be formed as various types of protrusions as shown in the enlarged views of the main parts in FIGS. The insulating raised projections 13 and the raised projections 12 shown in FIG. 21A have a substantially cylindrical shape, and the insulating raised projections 13 and the raised projections 12 shown in FIG. It has a substantially conical shape. In addition, the insulating raised protrusions 13 and the raised protrusions 12 shown in FIG. 21C have a ring shape (loop pile shape).

Moreover, the maximum diameter of the insulating raised protrusion 13 and the raised protrusion 12 can be set to about 50 μm to 1.0 mm. In addition, the density of each of the insulating raised protrusions 13 and the raised protrusions 12 may be appropriately adjusted according to the feeling of touch when contacting the insulating raised protrusions 13 and the raised protrusions 12.

  The insulating raised protrusions 13 and the raised protrusions 12 are arranged by, for example, planting hair on one surface of the base material 15. When flocking, a flocking device used in brush production or the like can be used. In addition, for example, a long line formed from a conductive material is sewn to the base material 15 so as to form a boundary of each predetermined region using a long filamentous body formed from an insulating material.

It is preferable that the conductive member 123 electrically connects the base ends of the cores 121 (the base-side ends of the cores 121). Further, instead of connecting the cores 121 to each other by the conductive thread-like members, for example, as shown in FIG.

  The input device 2d having such a configuration can detect a change in electrostatic capacitance when a user's finger or the like comes into contact with the raised protrusions 12 in a predetermined area, and can detect a predetermined area corresponding to the contact position. For example, when the input device 2d is used as an operation input unit of a TV operation remote controller, that is, a boundary portion between each channel key is configured by a plurality of insulating raised protrusions 13, In the case where a plurality of raised protrusions 12 are provided with each channel key corresponding to each predetermined area, when the user's finger or the like comes into contact with the raised protrusions 12 in the predetermined area corresponding to a certain channel. A change in electrostatic capacitance is detected, and the channel change operation of the operation remote controller can be performed based on the contact signal (output signal).

  In addition, the external circuit 50 not only detects the change in capacitance when it comes into contact with the raised protrusions 12, but also when a finger or the like is pushed into the raised protrusions 12 (the finger or the like is further brought closer to the substrate 15 side). It may be configured to detect a change in capacitance (when it is applied). In the case of such a configuration, for example, contact with the raised protrusions 12 in a predetermined area is detected based on a change in capacitance, and the contact signal (output signal) is used as a signal for recognizing the contact position. While being utilized, a signal detected based on a change in capacitance when a finger or the like is pushed into the raised protrusion 12 can be utilized as a signal for performing another operation related to the contact position.

The signal detected based on the change of the capacitance when the finger or the like is pushed into the raised protrusion 12 is utilized as the signal for selecting the channel before the change is determined. It can be used as a signal for decision (for channel change).

  The heights (lengths) of the raised protrusions 12 in each predetermined region may be formed to be uniform, or the plurality of raised protrusions 12 are at least two kinds of protrusions having different protrusion heights. You may comprise so that it may become an aggregate | assembly of a body. For example, as shown in the enlarged cross-sectional view of the main part in FIG. 23 (a) and the plan view in FIG. 23 (b) (plan view seen from the arrow D direction in FIG. 23 (a)) The raised protrusions 12g standing on the peripheral edge and the raised protrusions 12h standing on the inner side in each predetermined region may be configured to have different heights. In FIG. 23, the height of the raised protrusions 12h standing on the inner side in each predetermined region is configured to be higher than the height of the raised protrusions 12g standing on the peripheral edge. Further, as shown in the cross-sectional view of FIG. 24, at least two kinds of protrusions having different protrusion heights may be mixed on the base material 15 at random.

  Further, for example, in order to distinguish between the plurality of raised protrusions 12g standing on the peripheral edge in each predetermined region and the raised protrusions 12h standing on the inner side in each predetermined region, The plurality of raised protrusions 12g and the raised protrusions 12h provided on the inner side may have different colors.

  Here, the base material 15 in the input device 2d may be formed using either a transparent or opaque material. However, when the base material 15 is formed using a transparent material, for example, an illuminating body is provided below the input device 2d. By separately arranging and transmitting the light emitted from the illuminating body to the base material 15, it is possible to make the user clearly recognize the location of the input device 2d. In addition, when a finger or the like is brought into contact with the input device 2d, the illumination body is configured so that the contact position shines, thereby feeding back the contact position (input position) of the finger or the like with respect to the input device 2d to the user. Is possible.

  In the input device 2d according to the fourth embodiment having such a configuration, when a finger or the like touches (or approaches) the raised protrusions 12 in a predetermined area, the core made of the conductive material in the raised protrusions 12 is provided. 121 and the conductive member 123 that electrically connects the cores 121 are grounded via the capacitance of the human body, and the external circuit 50 detects the current value flowing through the structure at that time. By doing so, it is possible to detect the position (predetermined region) where the user has contacted. Here, since a plurality of insulating raised protrusions 13 are arranged in a portion corresponding to a boundary portion of each predetermined area, the raised protrusions 12 in one predetermined area that the user has contacted are Since it is possible to prevent contact with the raised protrusions 12 in another predetermined region arranged next to the predetermined region, it is possible to prevent the other predetermined region from detecting a change in the capacitance. It becomes possible to accurately detect the contact position of a finger or the like.

  Moreover, since the input device 2d according to the fourth embodiment includes the raised protrusions 12 formed in a raised shape, the user can obtain a feeling of touching the raised protrusions 12 (operation feeling). The input device 2d can be operated.

  Further, not only the detection of the change in capacitance when contacting the raised protrusions 12, but also when a finger or the like is pushed into the raised protrusion 12 (when the finger or the like is further brought closer to the substrate 15 side). By configuring the external circuit 50 so that a change in capacitance can be detected, an operation when the tip of the raised protrusion 12 is lightly touched with a finger or the like, and an operation when pushed into the raised protrusion 12 are used. Thus, it is possible to perform at least two steps of operations, and an input device 2d (touch panel) capable of so-called three-dimensional input can be easily configured.

  Further, when the plurality of raised protrusions 12 in each predetermined region are configured as an aggregate of at least two kinds of protrusions having different protrusion heights, the user is made to recognize a change in pressing feeling against the raised protrusions 12. Is possible. In such a configuration, it becomes possible to give the user a feeling of operation when pushing into the raised protrusions 12 with a finger or the like, and as described above, the tip of the raised protrusion 12 is lightly touched with a finger or the like. For the user who uses the input device 2d that can perform at least two steps of operation such as the operation at the time of pressing and the operation when pushed into the raised protrusion 12, it is possible to further enhance the operational feeling. It is possible to easily recognize whether the operation performed is a contact operation or a pressing operation on the raised protrusions 12 in each predetermined region. Further, in the case where the height of the raised protrusions 12h erected on the inner side in each predetermined region is configured to be higher than the height of the raised protrusions 12g erected on the peripheral edge, the input device 2c It is possible to clearly indicate to the user the optimum pressing location for each predetermined area.

  In addition, when the plurality of raised protrusions 12g standing on the peripheral edge in each predetermined region and the raised protrusions 12h standing on the inner side in each predetermined region are configured in different colors, the input device 2c It is possible to clearly indicate to the user the optimum pressing location for each predetermined area.

  Further, when the plurality of raised protrusions 12 in each predetermined region are configured as an aggregate of at least two kinds of protrusions having different protrusion heights, when a finger or the like is pushed into the raised protrusions 12, The raised protrusion 12 comes into contact with a finger or the like. As a result, when the finger or the like is pushed in, the capacitance changes greatly. By detecting this large change in capacitance, whether the user's operation is a contact operation with respect to the raised protrusions 12 is pushed in. It becomes possible for the input device 2d to easily determine whether the pressing operation is performed.

  In addition, as an application example of the input device 2d according to the fourth embodiment, the case where the input device 2d is used as the operation input unit of the TV operation remote controller has been described above. Can do. When the input device 2d is used as a bed sensor, for example, the input device 2d as a bed sensor is placed between a mat such as a bed and a sheet covered on the mat. When the user is lying on the bed, a plurality of predetermined areas in contact with the human body through the sheets can detect a lying state by detecting a change in capacitance, while the user is on the bed. When sitting, a plurality of predetermined areas corresponding to the sitting state will detect the contact with the human body through the sheets as a change in capacitance, whether the user is on the bed, or It is possible to detect the state of the user such as whether he / she is not sleeping, sleeping or sitting.

  Further, in the input device 2d according to the fourth embodiment, the form of each insulating raised protrusion 13 may be the same as that of the raised protrusion 12. Specifically, a core 121 formed of a conductive material and a cover 122 formed of a dielectric material that covers the surface of the core 121 may be provided. Thus, when it comprises so that the form of each insulating raising protrusion 13 may become the same as the form of the raising protrusion 12, the core bodies 121 with which the insulating raising protrusion 13 is provided are electrically connected by a conductive member. Otherwise, an effective insulating function can be exhibited and the above-described insulating raised protrusions 13 can function. Further, in the case of such a configuration, the fourth input device 2d can be manufactured more easily. For example, a filamentous body in which the surface of a long linear body formed of a conductive material is covered with a dielectric material is sewn to the entire area of the base material 15, and then the surface of the base material 15 is formed into a plurality of predetermined regions. In areas other than the areas set as insulating boundaries to be partitioned (inner areas of each predetermined area), only the filaments sewn on the base material 15 are electrically connected to each other by a conductive member, and then sandpaper, sandcloth The input device 2d can be manufactured by raising the hair using a sand net, a sand roll, a brush, a needle cloth, or the like. In other words, it is possible to form the raised protrusions 12 and the insulating raised protrusions 13 by using only the filaments for forming the raised protrusions 12, and separately form the filaments (formed from insulating materials) having different structures. The step of sewing the long filamentous body) to the base material 15 can be omitted, and the fourth input device 2d can be more easily manufactured.

  In addition, in the input device 2d according to the fourth embodiment, in each predetermined region, the conductive member 123 that connects the cores 121 included in the raised protrusions 12 is connected to the raised protrusions 12 by the user's finger. The external circuit 50 that detects the change in capacitance when the contact is made and the like, and generates an output signal based on the change in capacitance, is electrically connected to each other. Although it is configured so that contact or the like can be individually recognized, it is not limited to such a configuration. For example, the input device 2d according to the fourth embodiment can be configured as follows. That is, as shown in the plan view of FIG. 25 (a), the plurality of predetermined regions include a first band-shaped set group 8 composed of first band-shaped regions 8a in which the predetermined regions are connected in a band shape along one direction; As shown in the plan view of FIG. 25 (b), the second belt-like set group 9 is composed of a second belt-like region 9a in which predetermined regions are connected in a belt shape along another direction different from the first belt-like region 8a. The plurality of raised protrusions 12 that are configured to be divided and are arranged in predetermined regions adjacent to each other in each first belt-like region 8 a are electrically connected to each other by the conductive members 123. The plurality of raised protrusions 12 that are configured and arranged in predetermined regions adjacent to each other in each second belt-shaped region 9a are configured such that the cores 121 are electrically connected to each other by a conductive member. To the input device 2d The contact position and the like, change in the electrostatic capacitance in the first strip set group 8, and may be detected based on a change in capacitance of the second strip set group 9. In FIG. 25 (a), the raised protrusions 12 arranged in a predetermined area constituting the first belt-shaped assembly group 8 are displayed in gray. Similarly, in FIG.25 (b), the raising processus | protrusion 12 arrange | positioned in the predetermined area | region which comprises the 2nd strip | belt-shaped collection group 9 is colored and displayed.

  More specifically, for example, when a user touches a finger or the like at a position indicated by a cross in FIG. 26, the first band region 8a1 in the first band set group 8 detects a change in capacitance. Thus, the lateral position (X direction position) of the contact position of the finger or the like is detected. In addition, the second belt-like regions 9a1 and 9a2 in the second belt-like set group 9 detect a change in capacitance, thereby detecting the vertical position (Y-direction position) of the contact position of the finger, etc. The coordinates (x, y) of the contact position can be calculated.
