　以下、本開示の実施の形態について詳述する。なお、本開示は、以下の実施の形態に限定されるのではなく、開示の本旨の範囲内で種々変形して実施できる。 Hereinafter, embodiments of the present disclosure will be described in detail. It should be noted that the present disclosure is not limited to the following embodiments, but can be variously modified and implemented within the scope of the main purpose of the disclosure.
　《入力素子》
　本開示の入力素子は、面内方向の伸長率に応じて電気抵抗値が増減する導電性布帛を有しており、導電性布帛は、押圧されていないときに、面内方向の伸長率が、第１の伸長率となり、かつ押圧されたときに、面内方向の伸長率が、第１の伸長率よりも小さい第２の伸長率、第１の伸長率よりも大きい第３の伸長率の順に変化するように、構成されている、入力素子である。 << Input element >>
The input element of the present disclosure has a conductive cloth whose electric resistance value increases or decreases according to the elongation rate in the in-plane direction, and the conductive cloth has an extension rate in the in-plane direction when not pressed. , The first elongation rate, and when pressed, the in-plane extension rate is smaller than the first extension rate, the second extension rate, and the third extension rate, which is larger than the first extension rate. It is an input element configured so as to change in the order of.
　本開示の入力素子では、導電性布帛が押圧されていない状態において、導電性布帛が、第１の伸長率となる状態で配置されている。そして、本開示の入力素子では、導電性布帛が押圧されると、導電性布帛の伸長率が増加し、その押圧の大きさ、より具体的には押圧により入力素子の導電性布帛の部分に印加される圧力の大きさ又は押圧による導電性布帛の入力素子における相対的な変位の大きさ等に応じて、第１の伸長率よりも小さい第２の伸長率、第１の伸長率よりも大きい第３の伸長率の順に変化する。 In the input element of the present disclosure, the conductive cloth is arranged in a state where the conductive cloth has a first elongation rate in a state where the conductive cloth is not pressed. Then, in the input element of the present disclosure, when the conductive cloth is pressed, the elongation rate of the conductive cloth increases, and the magnitude of the pressing, more specifically, the pressing causes the portion of the conductive cloth of the input element. Depending on the magnitude of the applied pressure or the magnitude of the relative displacement of the conductive fabric due to the pressure in the input element, the second elongation rate is smaller than the first elongation rate, and the first elongation rate is higher than the first elongation rate. It changes in the order of the large third elongation rate.
　導電性布帛は、伸長によって導電性部分、例えば導電性の糸や金属メッキ部分間の接触面積が変化するため、伸長率に応じて電気抵抗値が増減するという特性を有している。そのため、本開示の入力素子では、押圧が小さい場合と押圧が大きい場合とで、押圧されていない場合における電気抵抗値の増減が逆転する。 The conductive fabric has a characteristic that the electric resistance value increases or decreases according to the elongation rate because the contact area between the conductive portion, for example, the conductive thread or the metal-plated portion changes due to the elongation. Therefore, in the input element of the present disclosure, the increase / decrease of the electric resistance value in the case where the pressing is not pressed is reversed depending on the case where the pressing is small and the case where the pressing is large.
　伸長率の増加に比例して電気抵抗値が増加する導電性布帛を採用した場合を例に、より具体的に説明する。 A more specific explanation will be given by taking as an example a case where a conductive fabric whose electric resistance value increases in proportion to an increase in the elongation rate is used.
　このような導電性布帛を採用した本開示の入力素子では、押圧が所定の値よりも小さい場合には、導電性布帛が押圧されていない状態よりも、導電性布帛の伸長率が小さくなる。そのため、電気抵抗値は、導電性布帛が押圧されていない状態よりも小さくなる。これに対して、押圧が所定の値よりも大きい場合には、導電性布帛が押圧されていない状態よりも、導電性布帛の伸長率が大きくなる。そのため、電気抵抗値は、導電性布帛が押圧されていない状態よりも大きくなる。 In the input element of the present disclosure using such a conductive cloth, when the pressing is smaller than a predetermined value, the elongation rate of the conductive cloth is smaller than that in the state where the conductive cloth is not pressed. Therefore, the electric resistance value is smaller than that in the state where the conductive cloth is not pressed. On the other hand, when the pressing is larger than a predetermined value, the elongation rate of the conductive fabric is larger than that in the state where the conductive fabric is not pressed. Therefore, the electric resistance value becomes larger than that in the state where the conductive cloth is not pressed.
　したがって、用途を限定するものではないが、本開示の入力素子は、例えば押圧の大きさが所定の値か否かによって異なる入力を行うことができる素子や、押圧の大きさが所定の値以上である場合にのみ入力を行うことができる素子等として利用することができる。 Therefore, although the application is not limited, the input element of the present disclosure includes, for example, an element capable of performing different input depending on whether or not the pressing magnitude is a predetermined value, or a pressing magnitude of a predetermined value or more. It can be used as an element or the like that can perform input only in the case of.
　本開示の入力素子の具体的な構成は、例えば以下のようなものを挙げることができるが、これらに限定されない。 Specific configurations of the input element of the present disclosure include, but are not limited to, the following, for example.
　本開示の入力素子は、例えば、上記の導電性布帛に関する構成に加えて、弾性部材を更に有していることができ、導電性布帛は、弾性部材の少なくとも一部分を被覆するようにして配置されていることができ、導電性布帛は、押圧されていないときに、導電性布帛のうち少なくとも弾性部材を被覆している部分の面内方向の伸長率は、第１の伸長率であり、導電性布帛のうち、弾性部材を被覆している部分を、導電性布帛のうち弾性部材と対向しない面側から押圧したときに、導電性布帛のうち少なくとも弾性部材を被覆している部分の面内方向の伸長率が、第１の伸長率よりも小さい第２の伸長率、第１の伸長率よりも大きい第３の伸長率の順に変化するように、構成されていることができる。ここで、弾性部材は、基材上に配置されていることができる。 The input element of the present disclosure may further have an elastic member, for example, in addition to the above-mentioned configuration relating to the conductive fabric, and the conductive fabric is arranged so as to cover at least a part of the elastic member. When the conductive fabric is not pressed, the in-plane elongation rate of at least the portion of the conductive fabric covering the elastic member is the first elongation rate and is conductive. When the portion of the woven fabric covering the elastic member is pressed from the surface side of the conductive fabric that does not face the elastic member, at least the portion of the conductive fabric covering the elastic member is in the plane. The elongation rate in the direction can be configured to change in the order of a second elongation rate smaller than the first extension rate and a third extension rate larger than the first extension rate. Here, the elastic member can be arranged on the base material.
　図１～４を用いて、本開示の入力素子の構成の例を、より具体的に説明する。 An example of the configuration of the input element of the present disclosure will be described more specifically with reference to FIGS. 1 to 4.
　図１は、本開示の第１の実施形態に従う入力素子を押圧していない状態を示す模式図である。 FIG. 1 is a schematic diagram showing a state in which the input element according to the first embodiment of the present disclosure is not pressed.
　図１に示すように、本開示の第１の実施形態に従う入力素子１は、基材１０、弾性部材２０、及び導電性布帛３０を有している。図１に示すように、本開示の第１の実施形態に従う入力素子１では、基材１０上に弾性部材２０が配置されており、更に弾性部材２０の表面及び基材１０の表面を、導電性布帛３０が被覆している。ここで、弾性部材２０が基材１０上から突出するようにして配置されており、それによって、導電性布帛３０のうち少なくとも弾性部材２０を被覆している部分３１は、第１の伸長率まで引き延ばされている。 As shown in FIG. 1, the input element 1 according to the first embodiment of the present disclosure has a base material 10, an elastic member 20, and a conductive cloth 30. As shown in FIG. 1, in the input element 1 according to the first embodiment of the present disclosure, the elastic member 20 is arranged on the base material 10, and the surface of the elastic member 20 and the surface of the base material 10 are conductive. The sex cloth 30 is covered. Here, the elastic member 20 is arranged so as to protrude from the base material 10, whereby at least the portion 31 of the conductive fabric 30 covering the elastic member 20 is up to the first elongation rate. It has been stretched.
　次いで、図２における白い矢印で示すように、導電性布帛３０のうち、弾性部材２０を被覆している部分３１を、導電性布帛３０のうち弾性部材２０と対向しない面側から押圧すると、弾性部材２０が収縮して、押圧された部分３１の伸長率は、第１の伸長率よりも小さい第２の伸長率となる。 Next, as shown by the white arrow in FIG. 2, when the portion 31 of the conductive fabric 30 covering the elastic member 20 is pressed from the surface side of the conductive fabric 30 that does not face the elastic member 20, it becomes elastic. The member 20 contracts, and the extension rate of the pressed portion 31 becomes a second extension rate smaller than the first extension rate.
　次いで、図３における白い矢印で示すように、導電性布帛３０のうち、弾性部材２０を被覆している部分３１を、図２における押圧よりも更に押圧すると、弾性部材２０が更に収縮して、押圧された部分３１の伸長率は、第１の伸長率よりも大きい第３の伸長率となる。 Next, as shown by the white arrow in FIG. 3, when the portion 31 of the conductive fabric 30 covering the elastic member 20 is pressed further than the pressing in FIG. 2, the elastic member 20 further contracts. The elongation rate of the pressed portion 31 becomes a third extension rate larger than the first extension rate.
　ここで、伸長率の増加に比例して電気抵抗値が増加する導電性布帛３０を採用した場合、図１～３における、導電性布帛３０の電気抵抗値は、図４に示すように変化する。 Here, when the conductive cloth 30 whose electric resistance value increases in proportion to the increase in the elongation rate is adopted, the electric resistance value of the conductive cloth 30 in FIGS. 1 to 3 changes as shown in FIG. ..
　図１の状態において、導電性布帛３０は第１の伸長率Ｅ１を有しており、また、第１の電気抵抗値Ｒ１を有している。 In the state of FIG. 1, the conductive cloth 30 has a first elongation ratio E 1 and a first electric resistance value R 1 .
　この状態から、導電性布帛３０のうち、弾性部材２０を被覆している部分３１を、導電性布帛３０のうち弾性部材２０と対向しない面側から押圧して図２の状態になると、導電性布帛３０は面内方向に関して収縮して、伸長率が第１の伸長率Ｅ１より小さい第２の伸長率Ｅ２になる。そのため、このときの導電性布帛３０の電気抵抗値Ｒ２は、第１の電気抵抗値Ｒ１よりも小さい。 From this state, when the portion 31 of the conductive fabric 30 covering the elastic member 20 is pressed from the surface side of the conductive fabric 30 that does not face the elastic member 20, the state shown in FIG. 2 is obtained. The fabric 30 contracts in the in-plane direction to become a second elongation rate E2 whose elongation rate is smaller than the first extension rate E1. Therefore, the electric resistance value R 2 of the conductive cloth 30 at this time is smaller than the first electric resistance value R 1 .
　そして、図２の状態から更に、導電性布帛３０のうち弾性部材２０を被覆している部分３１を導電性布帛３０のうち弾性部材２０と対向しない面側から押圧して、図３の状態にすると、導電性布帛３０が面内方向に関して伸長して、その伸長率が、第１の伸長率Ｅ１より大きい第３の伸長率Ｅ３になる。そのため、このときの導電性布帛３０の電気抵抗値Ｒ３は、第１の電気抵抗値Ｒ１よりも大きい。 Then, from the state of FIG. 2, the portion 31 of the conductive cloth 30 covering the elastic member 20 is further pressed from the surface side of the conductive cloth 30 that does not face the elastic member 20 to bring about the state of FIG. Then, the conductive fabric 30 is stretched in the in-plane direction, and the stretch rate thereof becomes a third stretch rate E3 which is larger than the first stretch rate E1. Therefore, the electric resistance value R 3 of the conductive cloth 30 at this time is larger than the first electric resistance value R 1 .
　このように、本開示の第１の実施形態に従う入力素子は、例えば押圧の大きさが所定の値か否かによって異なる入力を行うことができる素子や、押圧の大きさが所定の値以上である場合にのみ入力を行うことができる素子等として利用することができる。 As described above, the input element according to the first embodiment of the present disclosure is, for example, an element capable of performing different input depending on whether or not the pressing magnitude is a predetermined value, or an element having a pressing magnitude of a predetermined value or more. It can be used as an element or the like that can input only in a certain case.
　なお、図１～４は、いずれも本開示の入力素子を限定する趣旨ではない。 Note that none of FIGS. 1 to 4 is intended to limit the input elements of the present disclosure.

　本開示の入力素子において、導電性布帛は、押圧されていないときに、面内方向の伸長率が、第１の伸長率となり、かつ押圧されたときに、面内方向の伸長率が、第１の伸長率よりも小さい第２の伸長率、第１の伸長率よりも大きい第３の伸長率の順に変化するように、構成されている。押圧の方向は、例えば導電性布帛の面と交差する任意の方向であってよい。 In the input element of the present disclosure, when the conductive fabric is not pressed, the in-plane elongation rate becomes the first elongation rate, and when pressed, the in-plane extension rate becomes the first. It is configured so that the second elongation rate smaller than the elongation rate of 1 and the third elongation rate larger than the first elongation rate change in this order. The direction of pressing may be, for example, any direction that intersects the surface of the conductive fabric.
　本開示の入力素子において、導電性布帛は、導電性布帛の面内方向の伸長率が第１の伸長率であるときの導電性布帛の電気抵抗値を、第１の電気抵抗値、導電性布帛の面内方向の伸長率が第２の伸長率であるときの導電性布帛の電気抵抗値を、第２の電気抵抗値、及び導電性布帛の面内方向の伸長率が第３の伸長率であるときの導電性布帛の電気抵抗値を、第３の電気抵抗値としたときに、第２の電気抵抗値＜第１の電気抵抗値＜第３の電気抵抗値を満たすか、第３の電気抵抗値＜第１の電気抵抗値＜第２の電気抵抗値を満たすことができる。 In the input element of the present disclosure, the conductive cloth has the electric resistance value of the conductive cloth when the elongation rate in the in-plane direction of the conductive cloth is the first elongation rate, and the first electric resistance value and the conductivity. The electric resistance value of the conductive cloth when the in-plane elongation rate of the cloth is the second elongation rate, the second electric resistance value, and the in-plane extension rate of the conductive cloth are the third elongation rate. When the electric resistance value of the conductive cloth at the ratio is the third electric resistance value, the second electric resistance value <the first electric resistance value <the third electric resistance value is satisfied, or the third electric resistance value is satisfied. It is possible to satisfy the electric resistance value of 3 <the first electric resistance value <the second electric resistance value.
　本開示の入力素子が、例えば図１～３のような構成を有している場合において、導電性布帛３０が第２の電気抵抗値＜第１の電気抵抗値＜第３の電気抵抗値を満たす場合には、導電性布帛３０の伸長率と電気抵抗値とは、図４のような関係を示すことができる。なお、図４において、第１の伸長率、第２の伸長率、及び第３の伸長率は、それぞれＥ１、Ｅ２、及びＥ３であり、第１の電気抵抗値、第２の電気抵抗値、及び第３の電気抵抗値は、それぞれＲ１、Ｒ２、及びＲ３である。 When the input element of the present disclosure has a configuration as shown in FIGS. 1 to 3, for example, the conductive cloth 30 has a second electric resistance value <first electric resistance value <third electric resistance value. When satisfied, the elongation rate of the conductive cloth 30 and the electric resistance value can show the relationship as shown in FIG. In FIG. 4, the first elongation rate, the second elongation rate, and the third elongation rate are E 1 , E 2 , and E 3 , respectively, and the first electric resistance value and the second electricity. The resistance value and the third electric resistance value are R 1 , R 2 , and R 3 , respectively.
　また、本開示の入力素子１が、例えば図１～３のような構成を有している場合において、導電性布帛３０が第３の電気抵抗値＜第１の電気抵抗値＜第２の電気抵抗値を満たす場合には、導電性布帛３０の伸長率と電気抵抗値とは、図５のような関係を示すことができる。なお、図４において、第１の伸長率、第２の伸長率、及び第３の伸長率は、それぞれＥ１、Ｅ２、及びＥ３であり、第１の電気抵抗値、第２の電気抵抗値、及び第３の電気抵抗値は、それぞれＲ’１、Ｒ’２、及びＲ’３である。 Further, when the input element 1 of the present disclosure has a configuration as shown in FIGS. 1 to 3, for example, the conductive cloth 30 has a third electric resistance value <first electric resistance value <second electric power. When the resistance value is satisfied, the elongation rate of the conductive cloth 30 and the electric resistance value can show the relationship as shown in FIG. In FIG. 4, the first elongation rate, the second elongation rate, and the third elongation rate are E 1 , E 2 , and E 3 , respectively, and the first electric resistance value and the second electricity. The resistance value and the third electric resistance value are R'1, R'2 , and R'3 , respectively.
　なお、第２の電気抵抗値＜第１の電気抵抗値＜第３の電気抵抗値を満たす導電性布帛としては、例えば導電性布帛の面内方向の伸長率の増加に応じて電気抵抗値が増加するもの、より具体的には、導電性の繊維及び随意に非導電性の繊維によって形成された布帛、又は非導電性の布帛を導電化処理、例えば金属メッキ等された布帛を挙げることができるが、これに限定されない。原理によって限定するものではないが、これらの導電性布帛は、伸長によって繊維間に間隙が生じることで導電性の部分間の接触面積が低下する等により、伸長率の増加に応じて電気抵抗値が増加すると考えられる。 As the conductive cloth satisfying the second electric resistance value <first electric resistance value <third electric resistance value, for example, the electric resistance value increases as the elongation rate in the in-plane direction of the conductive cloth increases. Examples include those that increase, more specifically, fabrics formed of conductive fibers and optionally non-conductive fibers, or fabrics obtained by subjecting non-conductive fabrics to a conductive treatment, such as metal plating. Yes, but not limited to this. Although not limited by the principle, these conductive fabrics have an electric resistance value according to an increase in the elongation rate due to a decrease in the contact area between the conductive portions due to a gap between the fibers due to the elongation.

What is reduced, more specifically, the contact area between the conductive fibers is small in the non-stretched state, and the contact area between the conductive fibers is increased when stretched. , But not limited to, fabrics formed of conductive fibers and optionally non-conductive fibers.
