Description

スイッチおよびそれを用いた入力装置Switch and input device using the same
　本開示は、各種電子機器の入力操作部に用いられるスイッチおよびそれを用いた入力装置に関する。 The present disclosure relates to a switch used in an input operation unit of various electronic devices and an input device using the switch.
　各種電子機器は、入力操作部を指でタッチ操作して入力操作をする。このような電子機器の代表は、スマートフォン等の携帯用の電子機器である。近年では、自動車の車両内に搭載される各種の電子機器についても指によるタッチ操作で入力操作をする入力操作部を有する電子機器も増えている。 Various electronic devices perform input operations by touching the input operation unit with a finger. A representative example of such an electronic device is a portable electronic device such as a smartphone. In recent years, an increasing number of electronic devices have an input operation unit for performing an input operation by a finger touch operation for various electronic devices mounted in a vehicle.
　入力操作部への指によるタッチ操作で入力操作をする入力装置として、特許文献１が知られている。 Patent Document 1 is known as an input device that performs an input operation by a finger touch operation on the input operation unit.
　特許文献１による入力装置は、外装パネル内にセンサシートを装着して構成されている。センサシートは、互いに独立した静電容量式のセンサ部を複数箇所に有する。そして、外装パネルに設けられたキー部毎に各センサ部が対応して配置されている。 The input device according to Patent Document 1 is configured by mounting a sensor sheet in an exterior panel. The sensor sheet has a plurality of capacitive sensor units that are independent of each other. And each sensor part is arrange | positioned corresponding to every key part provided in the exterior panel.
　入力操作時には、操作者は、キー部上を指でタッチ操作する。これによって、指のタッチ位置に応じたセンサ部に静電容量の変化が生じる。その静電容量の変化を電子機器の制御部が検出する。制御部は、この一回目の静電容量の変化を検出した際、操作されたキー部に割り当てられた機能が選択された（以下、「予告操作」と表す）と判定する。 During the input operation, the operator touches the key part with a finger. As a result, a change in capacitance occurs in the sensor unit according to the touch position of the finger. The control unit of the electronic device detects the change in capacitance. When detecting the first capacitance change, the control unit determines that the function assigned to the operated key unit is selected (hereinafter, referred to as “preliminary operation”).
　その後、タッチした指をキー部から離すと、タッチ位置に応じたセンサ部に再び静電容量の変化が生じる。その静電容量の変化を機器の制御部が検出する。制御部は、この二回目の静電容量の変化を検出した際、予告操作されている機能への決定操作がされたと判定し、その機能を作動させる。 After that, when the touched finger is released from the key part, the capacitance changes again in the sensor part according to the touch position. The control unit of the device detects the change in capacitance. When detecting the second change in the capacitance, the control unit determines that the determination operation for the function for which the preliminary notification operation has been performed is performed, and activates the function.

　本開示によるスイッチは、第１電極部を有する、第１電極シートと、第１電極部に間隔を空けて対向し、平面視において第１電極部の外縁よりも内側に設けられる第２電極部を含み、第１電極シートに対向して配置される、第２電極シートと、第１電極シートと第２電極シートとの間に配置され、圧縮可能である、弾性部材と、を備える。 The switch according to the present disclosure includes a first electrode sheet having a first electrode portion, a second electrode portion that faces the first electrode portion with a space therebetween and is provided on an inner side of the outer edge of the first electrode portion in plan view. A second electrode sheet disposed opposite to the first electrode sheet, and an elastic member disposed between the first electrode sheet and the second electrode sheet and compressible.
　この構成により、第１電極シート側からのタッチ操作を、第１電極部の電気的変化によって検出することができ、かつ、第１電極シート側からの押し込み操作を第２電極部の電気的変化によって検出することができる。 With this configuration, a touch operation from the first electrode sheet side can be detected by an electrical change of the first electrode portion, and a push operation from the first electrode sheet side can be detected by an electrical change of the second electrode portion. Can be detected.
　また、タッチ操作がなされた際に、タッチ操作を予告操作に割り当て、押し込み操作がなされた際に、決定操作に割り当てることにより、誤操作の発生を少なくできる。 In addition, when a touch operation is performed, the touch operation is assigned to a notice operation, and when a push-in operation is performed, the assignment operation is assigned to a decision operation.
　また、本開示による入力装置は、上述したスイッチと、スイッチが接続される制御部と、制御部により制御される告知部とを備える。この構成により、スイッチへの操作時に告知部を連動して作動させることによって、操作状態が判り易くなる。 The input device according to the present disclosure includes the above-described switch, a control unit to which the switch is connected, and a notification unit controlled by the control unit. With this configuration, the operation state is easily understood by operating the notification unit in conjunction with the operation of the switch.

　本実施の形態におけるスイッチおよびそれを用いた入力装置の説明に先立って、特許文献１による入力装置の課題について説明する。 Prior to the description of the switch and the input device using the switch in the present embodiment, the problem of the input device according to Patent Document 1 will be described.
　特許文献１による入力装置を、例えば車両内に搭載した場合、所望機能に割り当てられたキー部に指でタッチ操作する際、指が誤って他の箇所に触れてしまうこともある。誤って指が触れた箇所に他のキー部があった場合、指が離れた時点で他のキー部に応じた機能が作動するようになる。すなわち、操作者の意図しない機能が作動してしまう。つまり、誤操作の発生する可能性を有する。 When the input device according to Patent Document 1 is mounted in a vehicle, for example, when a finger is operated to touch a key portion assigned to a desired function, the finger may accidentally touch another part. If there is another key part where the finger is accidentally touched, the function corresponding to the other key part is activated when the finger is released. That is, a function unintended by the operator is activated. That is, there is a possibility that an erroneous operation occurs.
　そこで、本開示は、誤操作の発生を低減できるスイッチおよびそれを用いた入力装置を提供することを目的とする。 Therefore, an object of the present disclosure is to provide a switch that can reduce the occurrence of an erroneous operation and an input device using the switch.
　以下、本実施の形態について、図１～図９を用いて説明する。 Hereinafter, this embodiment will be described with reference to FIGS.

　図１～図５に示すように、スイッチユニット３は、本実施の形態によるスイッチ７を有する。スイッチ７は、上方位置に配される操作側となる第１電極シート１１と、第１電極シート１１の下方に第１電極シート１１に間隔を空けて対向して配された第２電極シート２２と、第１電極シート１１と第２電極シート２２との間に介在して配された弾性部材３０とを含む。なお、スイッチユニット３は、独立して構成されている二つのスイッチ７を有している。 As shown in FIGS. 1 to 5, the switch unit 3 has a switch 7 according to the present embodiment. The switch 7 includes a first electrode sheet 11 on the operation side disposed at an upper position, and a second electrode sheet 22 disposed below the first electrode sheet 11 and facing the first electrode sheet 11 with a space therebetween. And an elastic member 30 disposed between the first electrode sheet 11 and the second electrode sheet 22. The switch unit 3 has two switches 7 that are configured independently.
　第１電極シート１１は、図１に示すように、第１基材１１Ａと、第１基材１１Ａの下面に形成された第１電極部４１とを、少なくとも有している。 As shown in FIG. 1, the first electrode sheet 11 has at least a first base material 11A and a first electrode portion 41 formed on the lower surface of the first base material 11A.
　第１基材１１Ａは、光透過性を有するＰＥＴなどの樹脂フィルムからなる。第１基材１１Ａの厚みは例えば３０μｍ～３００μｍである。 1st base material 11A consists of resin films, such as PET which has a light transmittance. The thickness of the first base material 11A is, for example, 30 μm to 300 μm.
　図４に示すように、第１電極部４１は、平面視で、長手方向の寸法がＬ１、短手寸法がＬ２の矩形である。なお、第１電極部４１の外縁よりも平面視で内側の領域を「第１領域」と以下、表す。 As shown in FIG. 4, the first electrode portion 41 is a rectangle having a longitudinal dimension L1 and a short dimension L2 in plan view. In addition, the area | region inside in planar view rather than the outer edge of the 1st electrode part 41 is represented as a "1st area | region" hereafter.
　第１電極部４１は、図１に示すように、光透過性を有する第１導電層４１Ａと、第１導電層４１Ａの外周下面に細幅で外枠状に重ねて形成された第１外枠導電層４１Ｂとを含む。なお、図４では、第１外枠導電層４１Ｂを図示せず。 As shown in FIG. 1, the first electrode portion 41 includes a light-transmitting first conductive layer 41A and a first outer layer formed on the outer peripheral lower surface of the first conductive layer 41A in a thin outer frame shape. Frame conductive layer 41B. In FIG. 4, the first outer frame conductive layer 41B is not shown.
　第１導電層４１Ａは、光透過性を有する導電性ポリマー（材質は例えばポリチオフェン）製である。第１導電層４１Ａは、第１基材１１Ａの下面に重ねて導電性ポリマーを第１領域内に印刷して形成されている。 The first conductive layer 41A is made of a light-transmitting conductive polymer (for example, polythiophene). The first conductive layer 41A is formed by printing a conductive polymer in the first region so as to overlap the lower surface of the first base material 11A.
　第１外枠導電層４１Ｂは、第１導電層４１Ａの下面に重ねて銀ペーストを細幅に印刷して形成されている。なお、第１外枠導電層４１Ｂは、導電性を有するカーボンペーストなどで形成されてもよい。 The first outer frame conductive layer 41B is formed by printing a silver paste thinly on the lower surface of the first conductive layer 41A. The first outer frame conductive layer 41B may be formed of a carbon paste having conductivity.
　また、第１基材１１Ａの下面には、グランド（ＧＮＤ）用の周囲導体層４３も設けられている。なお、周囲導体層４３は図１のみに図示し、他の図面には図示していない。周囲導体層４３を図示するのを省略しているのは、図面が煩雑になるのを避けるためである。 Further, a surrounding conductor layer 43 for ground (GND) is also provided on the lower surface of the first base material 11A. The surrounding conductor layer 43 is shown only in FIG. 1 and is not shown in other drawings. The illustration of the surrounding conductor layer 43 is omitted in order to prevent the drawing from becoming complicated.
　周囲導体層４３は、第１電極部４１の外縁に対して所定間隔を空けて、第１電極部４１の周囲をとり囲む第１電極部４１以外の領域に配設されている。なお、周囲導体層４３は、第１基材１１Ａの上面側に同様に設けてもよいし、または上面側のみに設けた構成等としてもよい。また、周囲導体層４３は、例えばメッシュ状などの構成にすると好ましいが、特に構成が限定されることはない。周囲導体層４３の配設の有無等は、必要に応じて適宜決定すればよい。 The surrounding conductor layer 43 is disposed in a region other than the first electrode portion 41 surrounding the first electrode portion 41 with a predetermined interval from the outer edge of the first electrode portion 41. In addition, the surrounding conductor layer 43 may be similarly provided on the upper surface side of the first base material 11A, or may be provided only on the upper surface side. The surrounding conductor layer 43 is preferably configured in a mesh shape, for example, but the configuration is not particularly limited. The presence or absence of the surrounding conductor layer 43 may be appropriately determined as necessary.
　第１電極部４１および周囲導体層４３は、第１基材１１Ａに下面側から設けられた光透過性を有する第１樹脂層４５で覆われている。なお、第１樹脂層４５の図示についても周囲導体層４３と同様に、図１のみに図示している。 The first electrode part 41 and the surrounding conductor layer 43 are covered with a first resin layer 45 having light transmissivity provided on the first base 11A from the lower surface side. Note that the first resin layer 45 is illustrated only in FIG. 1 as in the case of the surrounding conductor layer 43.
　第１外枠導電層４１Ｂは、図２などに示すように、第１引き出し部４７の一端に繋がっており、第１引き出し部４７の他端は第１基材１１Ａに設けられた第１テール部１１Ｂに引き回されている。 As shown in FIG. 2 and the like, the first outer frame conductive layer 41B is connected to one end of the first lead portion 47, and the other end of the first lead portion 47 is a first tail provided on the first base material 11A. It is routed to the part 11B.
　言い換えると、第１電極シート１１の第１電極部４１は、第１引き出し部４７を介して第１テール部１１Ｂに引き出されている。なお、第１外枠導電層４１Ｂと第１引き出し部４７とは、導電性を有する同じ導電ペースト等を用いて同時に設けると好ましい。なお、第１外枠導電層４１Ｂを設けない場合には、第１導電層４１Ａに第１引き出し部４７を直接接続した構成にすればよい。 In other words, the first electrode part 41 of the first electrode sheet 11 is drawn out to the first tail part 11B via the first lead part 47. Note that the first outer frame conductive layer 41B and the first lead portion 47 are preferably provided simultaneously using the same conductive paste having conductivity. If the first outer frame conductive layer 41B is not provided, the first lead portion 47 may be directly connected to the first conductive layer 41A.
　第１電極シート１１の下方には、第２電極シート２２が配置されている。第１電極シート１１と第２電極シート２２は、間隔を空けて対向している。第１電極シート１１と第２電極シート２２との間には、弾性部材３０が介在して配されている。弾性部材３０についての説明は後述する。 The second electrode sheet 22 is disposed below the first electrode sheet 11. The first electrode sheet 11 and the second electrode sheet 22 are opposed to each other with a space therebetween. An elastic member 30 is interposed between the first electrode sheet 11 and the second electrode sheet 22. The description of the elastic member 30 will be described later.
　第２電極シート２２は、第２基材２２Ａと、第２基材２２Ａの下面に形成された第２電極部５２とを、少なくとも有している。 The second electrode sheet 22 has at least a second base material 22A and a second electrode portion 52 formed on the lower surface of the second base material 22A.
　第２基材２２Ａは、光透過性を有するＰＥＴなどの樹脂フィルムからなる。第２基材２２Ａの厚みは例えば３０μｍ～３００μｍである。 The second base material 22A is made of a resin film such as PET having optical transparency. The thickness of the second base material 22A is, for example, 30 μm to 300 μm.
　図４に示すように、第２電極部５２は、平面視で、長手方向の寸法がＬ３、短手方向の寸法がＬ４の矩形である。なお、第２電極部５２の外縁よりも平面視で内側の領域を「第２領域」と以下、表す。 As shown in FIG. 4, the second electrode portion 52 is a rectangle having a longitudinal dimension of L3 and a lateral dimension of L4 in plan view. In addition, the area | region inside in planar view rather than the outer edge of the 2nd electrode part 52 is represented as a "2nd area | region" below.
　第２領域（第２電極部５２に対応）の面積は、第１領域（第１電極部４１に対応）の面積より小さい。図４に示すように、寸法Ｌ３は上述した第１電極部４１の長手方向の寸法Ｌ１よりも小さく、寸法Ｌ４は上述した第１電極部４１の短手方向の寸法Ｌ２よりも小さい。 The area of the second region (corresponding to the second electrode part 52) is smaller than the area of the first region (corresponding to the first electrode part 41). As shown in FIG. 4, the dimension L3 is smaller than the dimension L1 in the longitudinal direction of the first electrode part 41 described above, and the dimension L4 is smaller than the dimension L2 in the lateral direction of the first electrode part 41 described above.
　第２電極部５２の構成は、第１電極部４１の構成と同様である。つまり、第２電極部５２は、図１に示すように、第２領域に形成されている光透過性を有する第２導電層５２Ａと、第２導電層５２Ａの外周下面に細幅で外枠状に重ねて形成される第２外枠導電層５２Ｂとを含む。なお、図４では、第２外枠導電層５２Ｂを図示せず。 The configuration of the second electrode unit 52 is the same as the configuration of the first electrode unit 41. That is, as shown in FIG. 1, the second electrode portion 52 includes a light-transmitting second conductive layer 52A formed in the second region, and a narrow outer frame on the outer peripheral lower surface of the second conductive layer 52A. And a second outer frame conductive layer 52B formed to overlap each other. In FIG. 4, the second outer frame conductive layer 52B is not shown.
　第２導電層５２Ａは、光透過性を有する導電性ポリマー（材質は例えばポリチオフェン）製である。第２導電層５２Ａは、第２基材２２Ａの下面に重ねて導電性ポリマーを第２領域内に印刷して形成されている。第２外枠導電層５２Ｂは、第２導電層５２Ａの下面に重ねて導電性の高い銀ペーストを細幅に印刷して形成されている。なお、第２外枠導電層５２Ｂは、導電性を有するカーボンペーストなどで形成されてもよい。 The second conductive layer 52A is made of a light-transmitting conductive polymer (for example, polythiophene). The second conductive layer 52A is formed by printing a conductive polymer in the second region so as to overlap the lower surface of the second base material 22A. The second outer frame conductive layer 52B is formed by printing a thin silver paste with high conductivity on the lower surface of the second conductive layer 52A. The second outer frame conductive layer 52B may be formed of a conductive carbon paste or the like.
　そして、第２基材２２Ａの下面には、第１電極シート１１と同様に、グランド（ＧＮＤ）用の周囲導体層５４が設けられている。なお、周囲導体層５４は、第１電極シート１１の場合と同様に図１のみに図示している。 And the surrounding conductor layer 54 for ground | ground (GND) is provided in the lower surface of 22 A of 2nd base materials similarly to the 1st electrode sheet 11. As shown in FIG. The surrounding conductor layer 54 is shown only in FIG. 1 as in the case of the first electrode sheet 11.
　周囲導体層５４は、第２電極部５２の外縁に対して所定間隔を空けて、第２電極部５２の周囲をとり囲む第２電極部５２以外の領域に配設されている。第２電極シート２２の周囲導体層５４の配設領域は、第１電極シート１１の第１電極部４１との不要な容量結合を低減させるために、第１電極シート１１の周囲導体層４３に合わせて同一範囲に形成するとよい。なお、周囲導体層５４の詳細形状や設置の有無、第２基材２２Ａへの設置面の設定などは第１電極シート１１の場合と同様に必要に応じて適宜決定すればよい。 The surrounding conductor layer 54 is disposed in a region other than the second electrode portion 52 surrounding the second electrode portion 52 with a predetermined interval from the outer edge of the second electrode portion 52. The region where the peripheral conductor layer 54 of the second electrode sheet 22 is disposed is formed on the peripheral conductor layer 43 of the first electrode sheet 11 in order to reduce unnecessary capacitive coupling with the first electrode portion 41 of the first electrode sheet 11. It is good to form in the same range collectively. In addition, the detailed shape of the surrounding conductor layer 54, the presence / absence of installation, the setting of the installation surface on the second base material 22A, and the like may be appropriately determined as necessary as in the case of the first electrode sheet 11.
　第２電極部５２および周囲導体層５４は、第２基材２２Ａに下面側から設けられた光透過性を有する第２樹脂層５６で覆われている。第２樹脂層５６についても、第１電極シート１１の場合と同様に図１のみに図示している。 The second electrode portion 52 and the surrounding conductor layer 54 are covered with a second resin layer 56 having light transmissivity provided on the second base 22A from the lower surface side. The second resin layer 56 is also illustrated only in FIG. 1 as in the case of the first electrode sheet 11.
　さらに、第２外枠導電層５２Ｂは、図２などに示すように、第２引き出し部５８の一端に繋がっており、第２引き出し部５８の他端は第２基材２２Ａに設けられた第２テール部２２Ｂに引き回されている。 Further, as shown in FIG. 2 and the like, the second outer frame conductive layer 52B is connected to one end of the second lead portion 58, and the other end of the second lead portion 58 is provided on the second base material 22A. The two tail portions 22B are routed around.
　言い換えると、第２電極シート２２の第２電極部５２は、第２引き出し部５８を介して第２テール部２２Ｂに引き出されている。なお、第２外枠導電層５２Ｂと第２引き出し部５８とを導電性を有する同じ導電ペースト等を用いて同時に設けると好ましい。なお、第２外枠導電層５２Ｂを設けない場合には、第２導電層５２Ａに第２引き出し部５８を直接接続した構成にすると好ましいこと等は第１電極シート１１の場合と同様である。 In other words, the second electrode portion 52 of the second electrode sheet 22 is drawn out to the second tail portion 22B via the second lead portion 58. The second outer frame conductive layer 52B and the second lead portion 58 are preferably provided simultaneously using the same conductive paste having conductivity. In the case where the second outer frame conductive layer 52B is not provided, it is preferable that the second lead portion 58 is directly connected to the second conductive layer 52A, as in the case of the first electrode sheet 11.
　なお、第１テール部１１Ｂに対して上下に重ならない位置に第２テール部２２Ｂを設けると、電子機器への搭載作業が容易となる。 In addition, when the second tail portion 22B is provided at a position that does not overlap with the first tail portion 11B in the vertical direction, the mounting work on the electronic device is facilitated.
　そして、上方側に配置される第１電極シート１１の第１電極部４１と、下方側に配置される第２電極シート２２の第２電極部５２との中心位置同士は合わせ込まれている。 The center positions of the first electrode portion 41 of the first electrode sheet 11 disposed on the upper side and the second electrode portion 52 of the second electrode sheet 22 disposed on the lower side are aligned.
　言い換えると、第１電極部４１と第２電極部５２とは、平面視で透過して見ると、図３や図４に示すように、第２電極部５２の外縁の全てが第１電極部４１の外縁の内側に位置し、第１電極部４１と第２電極部５２は、上下方向で対向している。 In other words, when the first electrode portion 41 and the second electrode portion 52 are seen through in plan view, as shown in FIGS. 3 and 4, the entire outer edge of the second electrode portion 52 is the first electrode portion. The first electrode part 41 and the second electrode part 52 face each other in the vertical direction.
　第１電極シート１１と第２電極シート２２との間には、弾性部材３０が介在して配されている。 The elastic member 30 is interposed between the first electrode sheet 11 and the second electrode sheet 22.
　弾性部材３０は、圧縮変形が可能な材質で、例えばシリコーンゴム等からなる。弾性部材３０は、組み込みやすくするため、少なくとも弾性変形可能な固体の材質を用いる。弾性部材３０の材質などの選定時には、軽い力で圧縮変形し、圧縮変形後の復元状態を加味して選択すればよい。 The elastic member 30 is a material that can be compressed and deformed, and is made of, for example, silicone rubber. The elastic member 30 is made of at least an elastically deformable solid material so that it can be easily incorporated. When the material of the elastic member 30 is selected, the material may be selected by taking into account the restored state after compression deformation with a light force.
　本実施の形態では、弾性部材３０として、厚みが０．１ｍｍ～１ｍｍで、硬度０～５度のシリコーンゴム製の薄板を使用している。なお、シリコーンゴムを用いる場合には、硬度の低いものであれば使用可能であり、所望の製品特性に応じて適する硬度のものを選択して使用すればよい。 In this embodiment, a thin sheet made of silicone rubber having a thickness of 0.1 mm to 1 mm and a hardness of 0 to 5 degrees is used as the elastic member 30. When silicone rubber is used, it can be used as long as it has low hardness, and it may be selected and used according to desired product characteristics.
　弾性部材３０は、枠部３２と、枠部３２内を桟状に繋ぐ線状部３４を有する（図２などを参照）。 The elastic member 30 has a frame portion 32 and a linear portion 34 that connects the inside of the frame portion 32 in a frame shape (see FIG. 2 and the like).
　つまり、一つのスイッチ７の配設箇所に応じて、弾性部材３０は、横に並ぶほぼ同じ形状の三つの矩形孔が上下に貫通して設けられ、その三つの矩形孔を囲む周囲部分が枠部３２になって、矩形孔同士の間の残部が二つの線状部３４になっている。線状部３４同士は平行関係の直線状である。すなわち、線状部３４の第１の方向（図４の左右方向）における幅は、第２電極部５２の第１の方向における寸法（Ｌ３）よりも狭い。 That is, the elastic member 30 is provided with three rectangular holes of substantially the same shape horizontally arranged vertically depending on the location of one switch 7, and the surrounding portion surrounding the three rectangular holes is a frame. The remaining portion between the rectangular holes becomes two linear portions 34. The linear portions 34 are linear in a parallel relationship. That is, the width of the linear portion 34 in the first direction (left-right direction in FIG. 4) is narrower than the dimension (L3) of the second electrode portion 52 in the first direction.
　なお、本実施の形態では、1つの第２電極部５２の上方に、２つの線状部３４が配置されているが、必ずしも２つの線状部３４が配置される必要はない。１つの第２電極部５２の上方に、１つだけの線状部３４が配置されても良いし、３つ以上の線状部３４が配置されても良い。１つの第２電極部５２の上方に少なくとも１つの線状部３４が配置されていれば良い。 In the present embodiment, the two linear portions 34 are disposed above one second electrode portion 52, but the two linear portions 34 are not necessarily disposed. Only one linear portion 34 may be disposed above one second electrode portion 52, or three or more linear portions 34 may be disposed. It suffices that at least one linear portion 34 is disposed above one second electrode portion 52.
　また、本実施の形態では、第１電極部４１、第２電極部５２は長方形であるが、必ずしも長方形である必要はない。他の形状であっても良い。つまり、第１電極部４１の外縁よりも第２電極部５２の外縁が内側に設けられていれば、第１電極部４１および第２電極部５２の形状は矩形以外であってもよい。 In the present embodiment, the first electrode part 41 and the second electrode part 52 are rectangular, but they are not necessarily rectangular. Other shapes may be used. That is, the shape of the first electrode part 41 and the second electrode part 52 may be other than a rectangle as long as the outer edge of the second electrode part 52 is provided inside the outer edge of the first electrode part 41.
　また、本実施の形態では、線状部３４は、第２電極部５２の短手方向（図４の上下方向）に延伸しているが、第２電極部５２の長手方向（図４の左右方向）に沿って延伸するように配置しても良い。更には、線状部３４は斜め方向に配置して良い。つまり、第２電極部５２の上方に少なくとも１つの線状部３４が配置されていれば良い。また、線状部３４の全ての領域が、第２電極部５２に重なっている必要はない。つまり、少なくとも1箇所だけ、線状部３４の幅方向に跨って、第２電極部５２が重なりあっていれば良い。 In the present embodiment, the linear portion 34 extends in the short direction of the second electrode portion 52 (vertical direction in FIG. 4), but the longitudinal direction of the second electrode portion 52 (left and right in FIG. 4). You may arrange | position so that it may extend | stretch along (direction). Furthermore, the linear part 34 may be arranged in an oblique direction. That is, it is sufficient that at least one linear portion 34 is disposed above the second electrode portion 52. Further, it is not necessary that the entire region of the linear portion 34 overlaps the second electrode portion 52. That is, it is sufficient that the second electrode portion 52 overlaps at least one place across the width direction of the linear portion 34.
　そして、弾性部材３０は、図３に示すように、線状部３４が第１電極部４１と第２電極部５２の短手方向に沿って平行方向に伸び、かつ枠部３２の内縁が第１電極部４１に対して外方に位置するように配置されて組み込まれている。 As shown in FIG. 3, the elastic member 30 has the linear portion 34 extending in the parallel direction along the short direction of the first electrode portion 41 and the second electrode portion 52, and the inner edge of the frame portion 32 is the first edge. It arrange | positions so that it may be located in the outer side with respect to the 1 electrode part 41, and is integrated.
　このように、当該実施の形態では、対向する第１電極部４１と第２電極部５２とは、線状部３４および第２基材２２Ａを介して上下で対向している。言い換えると、第１電極シート１１の第１領域と第２電極シート２２の第２領域の間には二つの線状部３４のみが介在して位置し、その他の部分は空間になっている。これであれば、弾性部材３０の圧縮変形を軽い力で生じさせることができる。つまり、第１電極シート１１側からの押し込み操作時に操作性に優れるように容易に構成できる。 Thus, in the present embodiment, the first electrode portion 41 and the second electrode portion 52 that face each other face each other up and down via the linear portion 34 and the second base material 22A. In other words, only two linear portions 34 are interposed between the first region of the first electrode sheet 11 and the second region of the second electrode sheet 22, and the other portions are spaces. If it is this, the compressive deformation of the elastic member 30 can be produced with a light force. That is, it can be easily configured to be excellent in operability at the time of pushing operation from the first electrode sheet 11 side.
　なお、上述した弾性部材３０に設けられた空間は、押し込み操作時に圧縮変形する線状部３４の逃げ部として機能する箇所ともなる。なお、線状部３４の幅の設定や設置本数などは特に限定はされない。また、線状部３４は直線状以外であってもよい。本実施の形態では第２電極部５２よりも細い幅の線状部３４を配置しているが、平面視において第１領域の全てまたは第２領域の全てが弾性部材３０で覆われるように弾性部材３０の形状を設定してもよい。 In addition, the space provided in the elastic member 30 described above also serves as a portion that functions as a relief portion of the linear portion 34 that is compressed and deformed during the pushing operation. In addition, the setting of the width | variety of the linear part 34, the number of installation, etc. are not specifically limited. Moreover, the linear part 34 may be other than linear. In the present embodiment, the linear portion 34 having a width narrower than that of the second electrode portion 52 is disposed. However, the elastic portion 30 is elastic so that all of the first region or all of the second region is covered with the elastic member 30 in plan view. The shape of the member 30 may be set.
　そして、第１電極シート１１と第２電極シート２２は、弾性部材３０の外側位置で粘着テープ６０によって貼り合わせられている（図２参照）。 And the 1st electrode sheet 11 and the 2nd electrode sheet 22 are pasted together by the adhesive tape 60 in the outside position of elastic member 30 (refer to Drawing 2).
　なお、弾性部材３０は、第１電極シート１１と第２電極シート２２との間で挟持のみされている状態でもよいし、弾性部材３０の上下面を粘着テープ（図示せず）で第１電極シート１１と第２電極シート２２に粘着してもよい。弾性部材３０の上下面を粘着テープで粘着させる場合には、線状部３４を細い幅に設定する場合などもあるため、枠部３２のみを粘着保持させると好ましい。なお、線状部３４を粘着保持させていない構成とすると、第１電極シート１１からの押し込み量が粘着剤を介さずに線状部３４に直接伝達される構成にできる。換言すれば、線状部３４の上面は第１電極シート１１の下面に接し、線状部３４の下面は第２電極シート２２の上面に接していると好ましい。 The elastic member 30 may be in a state where it is only sandwiched between the first electrode sheet 11 and the second electrode sheet 22, or the upper and lower surfaces of the elastic member 30 are bonded to the first electrode with an adhesive tape (not shown). The sheet 11 and the second electrode sheet 22 may be adhered. When the upper and lower surfaces of the elastic member 30 are adhered with an adhesive tape, the linear portion 34 may be set to have a narrow width. Therefore, it is preferable that only the frame portion 32 is adhered and held. In addition, if it is set as the structure which is not carrying out adhesion holding of the linear part 34, it can be set as the structure which the amount of pushing from the 1st electrode sheet 11 is directly transmitted to the linear part 34 without an adhesive. In other words, the upper surface of the linear portion 34 is preferably in contact with the lower surface of the first electrode sheet 11, and the lower surface of the linear portion 34 is preferably in contact with the upper surface of the second electrode sheet 22.
　以上のように、本実施の形態によるスイッチ７は構成されている。 As described above, the switch 7 according to the present embodiment is configured.
　そして、スイッチ７を二つ備えているスイッチユニット３は、スイッチ７の第１電極部４１および第２電極部５２を、第１引き出し部４７および第２引き出し部５８を介して制御部（第１制御部１４４、第２制御部１４６）に接続して搭載される。また、スイッチ７は、第２電極シート２２の下面を、硬質の材質で形成された平坦面１２２の上に配置して、ケース１２０に搭載される。 The switch unit 3 including two switches 7 connects the first electrode part 41 and the second electrode part 52 of the switch 7 via the first lead part 47 and the second lead part 58 (first part). The control unit 144 and the second control unit 146) are connected and mounted. The switch 7 is mounted on the case 120 with the lower surface of the second electrode sheet 22 disposed on the flat surface 122 formed of a hard material.
　なお、第１制御部１４４、第２制御部１４６、平坦面１２２、ケース１２０については、図７を参照しながら後述する。 The first control unit 144, the second control unit 146, the flat surface 122, and the case 120 will be described later with reference to FIG.
　スイッチ７がケース１２０に搭載された状態で、操作者がスイッチ７の配設位置に応じた第１電極シート１１上の位置に指を近づけていきタッチ操作をすると、第１電極部４１に静電容量の変化が生じる。制御部は、このタッチ操作による静電容量の変化を検出して、スイッチ７のタッチ操作に割り当てられた所定機能の制御を行う。 When the switch 7 is mounted on the case 120 and the operator performs a touch operation by bringing a finger close to the position on the first electrode sheet 11 corresponding to the position where the switch 7 is disposed, A change in capacitance occurs. The control unit detects a change in capacitance due to the touch operation, and controls a predetermined function assigned to the touch operation of the switch 7.
　なお、タッチ操作時の検出の精度を上げるには、タッチ操作時の静電容量の変化の大きさも関与する。すなわち、タッチ操作を第２領域（第２電極部５２の面積）で検出するよりも、第２領域よりも広い第１領域（第１電極部４１の面積）で検出する方が静電容量の大きい変化が得られる。このため、本実施の形態では、タッチ操作時の検出精度は良好である。 Note that the magnitude of the change in capacitance during the touch operation is also involved in increasing the detection accuracy during the touch operation. That is, it is easier to detect the touch operation in the first region (area of the first electrode portion 41) wider than the second region than in the second region (area of the second electrode portion 52). A big change is obtained. For this reason, in this Embodiment, the detection accuracy at the time of touch operation is favorable.
　また、タッチ操作の検出時に、第１電極シート１１の周囲導体層４３、第２電極シート２２の第２電極部５２、周囲導体層５４をグランドに接地しておくと、タッチ操作による第１電極部４１の静電容量の変化はさらに精度よくかつ良好に得られ、制御部によるタッチ操作の検出精度が向上する。 Further, when the touch operation is detected, if the surrounding conductor layer 43 of the first electrode sheet 11, the second electrode portion 52 of the second electrode sheet 22, and the surrounding conductor layer 54 are grounded to the ground, the first electrode by the touch operation is obtained. The change in the capacitance of the unit 41 is obtained with higher accuracy and better, and the detection accuracy of the touch operation by the control unit is improved.
　その後、引き続いて、操作者は、第１電極シート１１へのタッチ操作状態からその箇所へ押圧力を加えた押し込み操作を行う。 Then, subsequently, the operator performs a push-in operation in which a pressing force is applied to the location from the touch operation state on the first electrode sheet 11.
　図５の矢印に示すように、操作者が指で下方向に押圧力を加えると、弾性部材３０の二つの線状部３４は下方側に圧縮されていく。同時に、第１電極シート１１の当該箇所が部分的に下方に撓み、第１電極部４１の当該箇所が全体的に下方に下がる。押し込み操作距離としては、０．０３ｍｍ～０．０７ｍｍ程度である。なお、この際、枠部３２の内縁も少し圧縮状態になると好ましい。 As shown by the arrows in FIG. 5, when the operator applies a downward pressing force with a finger, the two linear portions 34 of the elastic member 30 are compressed downward. At the same time, the portion of the first electrode sheet 11 is partially bent downward, and the portion of the first electrode portion 41 is lowered downward. The pushing operation distance is about 0.03 mm to 0.07 mm. At this time, it is preferable that the inner edge of the frame portion 32 is slightly compressed.
　第１電極部４１と第２電極部５２との間の間隔が縮まることによって、第１電極部４１と第２電極部５２との間で静電容量の変化が生じる。 When the distance between the first electrode part 41 and the second electrode part 52 is reduced, a change in capacitance occurs between the first electrode part 41 and the second electrode part 52.
　この押し込み操作状態での静電容量の変化を検出するにあたって、本実施の形態では、制御部による制御で、第１電極部４１をグランドに接地し、第２電極部５２をセンシング状態にしている。さらに、第１電極シート１１の周囲導体層４３、第２電極シート２２の周囲導体層５４はグランドに接地しておくとよい。 In this embodiment, when detecting the change in capacitance in the pushing operation state, the first electrode portion 41 is grounded and the second electrode portion 52 is in the sensing state under the control of the control portion. . Furthermore, the surrounding conductor layer 43 of the first electrode sheet 11 and the surrounding conductor layer 54 of the second electrode sheet 22 are preferably grounded to the ground.
　上述したように、スイッチ７は、平面視において（例えば、図１の上方または下方から見た場合）、第２電極部５２の外縁は、第１電極部４１の外縁より内側にある。また、第２電極シート２２と第１電極部４１は、間隔を空けて対向している。つまり、平面視で、第１電極部４１内に第２電極部５２が収まる位置で対向している。この構成であれば、押し込み操作状態であってもグランドに接地された第１電極部４１の下に第２電極部５２が殆ど隠れた状態になる。これであれば、操作中の指と第２電極部５２の間での不要な容量結合を低減でき、その影響を抑えることができる。 As described above, the switch 7 has the outer edge of the second electrode portion 52 inside the outer edge of the first electrode portion 41 in a plan view (for example, when viewed from above or below in FIG. 1). Further, the second electrode sheet 22 and the first electrode portion 41 are opposed to each other with a space therebetween. That is, they are opposed to each other at a position where the second electrode portion 52 is accommodated in the first electrode portion 41 in plan view. With this configuration, even in the pushing operation state, the second electrode portion 52 is almost hidden under the first electrode portion 41 grounded to the ground. If it is this, the unnecessary capacitive coupling between the finger in operation and the 2nd electrode part 52 can be reduced, and the influence can be suppressed.
　上記説明からも明らかなように、本実施の形態では、押し込み操作による第１電極部４１と第２電極部５２との間の静電容量の変化が安定して精度よく良好に得られる。このため、制御部による押し込み操作の検出精度が向上する。 As is clear from the above description, in the present embodiment, the change in capacitance between the first electrode portion 41 and the second electrode portion 52 due to the pushing operation can be obtained stably and accurately. For this reason, the detection accuracy of the pushing operation by the control unit is improved.
　なお、操作中の指と第２電極部５２の間での不要な容量結合を低減するには、平面視で第１電極部４１内に収まるように配置される第２電極部５２の外縁が、第１電極部４１の外縁に対して離れるほど好ましい。 In order to reduce unnecessary capacitive coupling between the finger being operated and the second electrode part 52, the outer edge of the second electrode part 52 arranged so as to be accommodated in the first electrode part 41 in a plan view is provided. The further away from the outer edge of the first electrode portion 41, the better.
　しかしながら、第２電極部５２を平面視において、小さくしすぎると、押し込み操作状態での静電容量の変化が小さくなる。よって、外縁同士の距離としては、第１電極部４１、第２電極部５２の位置決め誤差を含めない場合には０．１５ｍｍ以上を目安にするとよい。第１電極部４１、第２電極部５２の位置決め誤差などを含む場合には０．５ｍｍ以上あると好ましいが０．２５ｍｍ程度でもその効果は見込まれる。さらに、第１電極部４１、第２電極部５２の外縁同士の距離の設定時には、第１電極部４１と第２電極部５２の対向間の距離も影響するため、それらの全てを勘案しつつ適宜設定する必要がある。なお、第２電極部５２は３ｍｍ角以上の大きさであると好ましい。 However, if the second electrode portion 52 is made too small in plan view, the change in capacitance in the pushing operation state becomes small. Therefore, the distance between the outer edges may be set to 0.15 mm or more when the positioning error of the first electrode portion 41 and the second electrode portion 52 is not included. In the case of including positioning errors of the first electrode portion 41 and the second electrode portion 52, it is preferably 0.5 mm or more, but the effect is expected even at about 0.25 mm. In addition, when setting the distance between the outer edges of the first electrode part 41 and the second electrode part 52, the distance between the opposing sides of the first electrode part 41 and the second electrode part 52 also has an effect, so that all of them are taken into account. It is necessary to set appropriately. The second electrode portion 52 is preferably 3 mm square or larger.
　制御部（第１制御部１４４、第２制御部１４６）は、押し込み操作による静電容量の変化を検出してスイッチ７の押し込み操作に割り当てられた所定機能の制御を行う。 The control units (first control unit 144 and second control unit 146) detect a change in capacitance due to the pushing operation, and control a predetermined function assigned to the pushing operation of the switch 7.
　操作者が、押し込み操作をしている指を第１電極シート１１から離すと、弾性部材３０が自身の復元力で復元するなどして図１に示す押し込み前の状態に戻る。 When the operator removes the finger performing the pushing operation from the first electrode sheet 11, the elastic member 30 is restored by its own restoring force and the state before the pushing shown in FIG. 1 is restored.
　以上、説明したようにスイッチ７は、タッチ操作による静電容量の変化と、押し込み操作による静電容量の変化が精度よく良好に得られる。 As described above, the switch 7 can obtain a change in capacitance due to a touch operation and a change in capacitance due to a push-in operation with good accuracy.
　なお、従来品では、タッチ操作が所定機能の予告操作になり、その後のタッチ操作の解除で予告操作された機能の決定操作になっていた。 In addition, in the conventional product, the touch operation is a notification operation of a predetermined function, and the subsequent operation of the touch operation is a determination operation of the function operated by the notification operation.
　従来品に対して、本実施の形態においては、スイッチ７は、タッチ操作に対応する所定機能の予告操作が割り当てられている。そして、その後の押し込み操作に予告操作された所定機能の決定操作が割り当てられている。つまり、本実施の形態においては、タッチ操作の解除での誤操作の発生を大きく低減させることができる。 In contrast to the conventional product, in the present embodiment, the switch 7 is assigned a notice operation with a predetermined function corresponding to the touch operation. Then, a determination operation of a predetermined function that has been operated in advance is assigned to the subsequent pressing operation. That is, in the present embodiment, it is possible to greatly reduce the occurrence of an erroneous operation when the touch operation is released.
　〔入力装置１００〕
　次に、上述したスイッチユニット３を搭載した入力装置１００について説明する。 [Input device 100]
Next, the input device 100 equipped with the above-described switch unit 3 will be described.
　図６は本実施の形態によるスイッチユニットを搭載した入力装置の断面図である。図７は本実施の形態による入力装置の分解斜視図である。図８は本実施の形態による入力装置の上面図である。図９は本実施の形態による入力装置のスイッチ部分での断面図である。 FIG. 6 is a cross-sectional view of an input device equipped with a switch unit according to this embodiment. FIG. 7 is an exploded perspective view of the input device according to the present embodiment. FIG. 8 is a top view of the input device according to this embodiment. FIG. 9 is a cross-sectional view of the switch portion of the input device according to this embodiment.
　図６～図９に示すように、スイッチユニット３を搭載した入力装置１００は、上カバー１１０、スイッチユニット３、ケース１２０、配線基板１４０などを含む。 As shown in FIGS. 6 to 9, the input device 100 on which the switch unit 3 is mounted includes an upper cover 110, a switch unit 3, a case 120, a wiring board 140, and the like.
　ケース１２０は下方が開口した箱型で、材質はＡＢＳやＰＣなどの樹脂からなる。ケース１２０の上面位置には窪み部が設けられている。ケース１２０の窪み部の内底面は平坦面１２２（図７参照）を有する。 The case 120 has a box shape with an opening at the bottom, and is made of a resin such as ABS or PC. A recess is provided on the upper surface of the case 120. The inner bottom surface of the recessed portion of the case 120 has a flat surface 122 (see FIG. 7).
　スイッチユニット３は、ケース１２０の平坦面１２２上に両面粘着テープなどを用いて位置決めして装着されている。この装着方法は特に限定はされない。ケース１２０の平坦面１２２に配されたスイッチユニット３上は、ケース１２０に結合された上カバー１１０で覆われている。 The switch unit 3 is positioned and mounted on the flat surface 122 of the case 120 using a double-sided adhesive tape or the like. This mounting method is not particularly limited. The switch unit 3 arranged on the flat surface 122 of the case 120 is covered with an upper cover 110 coupled to the case 120.
　ケース１２０の下方開口の中空部内には配線基板１４０が収容されている。配線基板１４０には、コネクタ１４２（図６参照）が二つ装着されている。各々のコネクタ１４２には、スイッチユニット３の第１テール部１１Ｂと第２テール部２２Ｂとが挿入されている。これらによって、二つのスイッチ７は、第１引き出し部４７、第２引き出し部５８を介して配線基板１４０に実装された第１制御部１４４に接続されている。第１制御部１４４は、各スイッチ７への操作状態を検出する機能を有している。 The wiring board 140 is accommodated in the hollow portion of the lower opening of the case 120. Two connectors 142 (see FIG. 6) are attached to the wiring board 140. In each connector 142, the first tail portion 11B and the second tail portion 22B of the switch unit 3 are inserted. Accordingly, the two switches 7 are connected to the first control unit 144 mounted on the wiring board 140 via the first lead portion 47 and the second lead portion 58. The first control unit 144 has a function of detecting the operation state of each switch 7.
　また、配線基板１４０には第１告知部１４８も装着されている。第１告知部１４８はＬＥＤからなる。第１告知部１４８は第１制御部１４４により制御される。なお、第１制御部１４４はスイッチ７への操作状態の検出のみを行って所定信号を送出し、この所定信号を受ける他の制御部で第１告知部１４８が制御される構成でもよい。なお、第１告知部１４８は光による告知をするもの以外であってもよい。 In addition, a first notification unit 148 is also mounted on the wiring board 140. The 1st notification part 148 consists of LED. The first notification unit 148 is controlled by the first control unit 144. The first control unit 144 may be configured to only detect the operation state of the switch 7 and send a predetermined signal, and the first notification unit 148 may be controlled by another control unit that receives the predetermined signal. In addition, the 1st notification part 148 may be other than what performs notification by light.
　さらに、ケース１２０の下方開口の中空部内には、第２告知部１５０が収容されている。第２告知部１５０は、振動を発生して告知したり、音によって告知したりするもの等があげられるが、特に限定はされない。なお、以後の説明では、第２告知部１５０として、振動を発生する振動発生部を備える事例で説明する。 Furthermore, a second notification unit 150 is accommodated in the hollow part of the lower opening of the case 120. Examples of the second notification unit 150 include those that generate vibrations and notify by sound, but are not particularly limited. In the following description, an example in which the second notification unit 150 includes a vibration generation unit that generates vibration will be described.
　第２告知部１５０は、配線基板１４０に実装された第２制御部１４６に接続されている。第２制御部１４６は、第１制御部１４４に接続されており、第２制御部１４６は、第１制御部１４４からの信号に応じて第２告知部１５０での振動を発生させたり、その振動を停止させたりするなどの制御を行う機能を有している。なお、第２制御部１４６の機能を併せ持つ第１制御部１４４のみで構成してもよい。 The second notification unit 150 is connected to the second control unit 146 mounted on the wiring board 140. The second control unit 146 is connected to the first control unit 144, and the second control unit 146 generates vibrations in the second notification unit 150 in response to a signal from the first control unit 144, It has a function to perform control such as stopping vibration. In addition, you may comprise only the 1st control part 144 which has the function of the 2nd control part 146 together.
　そして、ケース１２０の下方開口部は、ケース１２０に結合されている下カバー１６０で覆われている。 The lower opening of the case 120 is covered with a lower cover 160 coupled to the case 120.
　上述した上カバー１１０は、光透過性を有する樹脂シートからなり、図７や図８に示すように、スイッチ７に対応する操作箇所１１５以外には塗装等がされている。各々の操作箇所１１５は、第２電極シート２２における第２外枠導電層５２Ｂよりも小さい範囲の矩形状に形成されており、それぞれの中には図示は省略するがＯＮ、ＯＦＦやアップ、ダウンなどのマーク表示がされている。なお、マーク表示のみが塗装等されずに残される等であってもよい。 The above-described upper cover 110 is made of a light-transmitting resin sheet, and is coated other than the operation location 115 corresponding to the switch 7 as shown in FIGS. Each operation place 115 is formed in a rectangular shape in a range smaller than the second outer frame conductive layer 52B in the second electrode sheet 22, and although not shown in each, ON, OFF, up, down Is displayed. Note that only the mark display may be left without being painted or the like.
　第１制御部１４４は、指でのタッチ操作状態を検出すると第１告知部１４８であるＬＥＤを点灯させる。第１告知部１４８が点灯した際、二つの操作箇所１１５は同時に照光される。これは、指でのタッチ操作状態では、操作中の操作箇所１１５が指で隠れてしまって、第１告知部１４８による光の告知が識別できないこともある。これを想定して、操作中ではない操作箇所１１５も同時に光の告知がされるようにしてタッチ操作状態になっているか否かの視認を可能に構成している。 When the first control unit 144 detects a touch operation state with a finger, the first control unit 144 turns on the LED that is the first notification unit 148. When the first notification unit 148 is turned on, the two operation points 115 are illuminated simultaneously. This is because, in the touch operation state with a finger, the operation location 115 being operated is hidden by the finger, and the light notification by the first notification unit 148 may not be identified. Assuming this, the operation location 115 that is not being operated is also notified of light at the same time so that it can be visually confirmed whether or not it is in a touch operation state.
　以上のように構成された入力装置１００は、詳細な図示などは省略するが、所定の電子機器の入力操作部などに組み込まれて使用される。 The input device 100 configured as described above is used by being incorporated in an input operation unit or the like of a predetermined electronic device, although detailed illustration is omitted.
　続いて、入力装置１００の操作状態などについて説明する。なお、スイッチ７の動作については上述説明と同様であるため、その説明は簡略化する。 Subsequently, the operation state of the input device 100 will be described. Since the operation of the switch 7 is the same as that described above, the description is simplified.
　まず、操作者が、上カバー１１０上からいずれかの操作箇所１１５を指でタッチ操作する。このタッチ操作によって、対応するスイッチ７の第１電極部４１に静電容量の変化が生じ、その変化を基に第１制御部１４４が操作状態を検出する。簡単に説明するが、第１制御部１４４は、予め設定された第１閾値を有し、タッチ操作による静電容量の変化を基にして演算した演算値が第１閾値を越えた時点で有効なタッチ操作がされていると判定する。 First, the operator touches any one of the operation points 115 from the upper cover 110 with a finger. By this touch operation, a change in capacitance occurs in the first electrode portion 41 of the corresponding switch 7, and the first control unit 144 detects the operation state based on the change. As will be briefly described, the first control unit 144 has a first threshold value set in advance, and is effective when the calculated value calculated based on the change in capacitance due to the touch operation exceeds the first threshold value. It is determined that a touch operation is being performed.
　そして、第１制御部１４４は、有効なタッチ操作がされていると判定した後、それを告知する制御を行う。つまり、第１告知部１４８であるＬＥＤを点灯させる制御を行う。第１告知部１４８としてなるＬＥＤは、二つの操作箇所１１５の直下の位置に夫々装着されており、第１制御部１４４による制御で同時に点灯する。 Then, after determining that an effective touch operation has been performed, the first control unit 144 performs control for notifying it. That is, control is performed to turn on the LED that is the first notification unit 148. The LEDs serving as the first notification unit 148 are respectively mounted at positions immediately below the two operation points 115 and are turned on simultaneously under the control of the first control unit 144.
　このとき、タッチ操作中の操作箇所１１５は指で隠れることもあるが、上述したように他方の操作箇所１１５も同時に照光されるため、操作者は、他方の操作箇所１１５の照光を視認して、有効なタッチ操作になっていることを識別できる。 At this time, the operation location 115 during the touch operation may be hidden by a finger, but as described above, the other operation location 115 is also illuminated at the same time, so the operator can visually recognize the illumination of the other operation location 115. , It can be identified that the touch operation is valid.
　また、第１制御部１４４は、有効なタッチ操作がされていると判定した時点で、タッチ操作中の操作箇所１１５に割り当てられている所定機能が予告操作されたと判定する。 In addition, when the first control unit 144 determines that an effective touch operation is performed, the first control unit 144 determines that a predetermined function assigned to the operation location 115 during the touch operation has been operated in advance.
　その後、操作者は、引き続いて指でタッチ操作した操作箇所１１５へ押圧力を加えた押し込み操作をする。 Thereafter, the operator performs a push-in operation in which a pressing force is applied to the operation portion 115 that is subsequently touch-operated with a finger.
　押し込み操作によって、操作箇所１１５が部分的に下方に撓み、第１電極シート１１の当該箇所が部分的に押し込まれて、対応するスイッチ７が押し込み操作状態になる。つまり、スイッチ７の第１電極部４１と第２電極部５２との間で静電容量の変化が生じ、その変化を基に第１制御部１４４が操作状態を検出する。 By the pushing operation, the operation place 115 is partially bent downward, the place of the first electrode sheet 11 is partially pushed, and the corresponding switch 7 enters the push operation state. That is, a change in capacitance occurs between the first electrode part 41 and the second electrode part 52 of the switch 7, and the first control unit 144 detects the operation state based on the change.
　なお、押し込み操作の検出の際、第１電極部４１をグランドに接地し、第２電極部５２をセンシング状態にすることは上述したとおりである。なお、簡単に説明するが、第１制御部１４４は、予め設定された第２閾値を有し、押し込み操作による静電容量の変化を基にして演算した演算値が第２閾値を越えた時点で有効な押し込み操作がされていると判定する。 As described above, when the push-in operation is detected, the first electrode portion 41 is grounded and the second electrode portion 52 is brought into a sensing state. As will be briefly described, the first control unit 144 has a preset second threshold value, and when the calculated value calculated based on the change in capacitance due to the pushing operation exceeds the second threshold value. It is determined that a valid push-in operation is performed.
　第１制御部１４４は、有効な押し込み操作がされていると判定した場合には、予告操作された所定機能への決定操作がされたと判別し、第１制御部１４４の制御によってその機能が作動される。 If the first control unit 144 determines that an effective push-in operation has been performed, the first control unit 144 determines that a determination operation for the predetermined function that has been operated in advance is performed, and the function is activated by the control of the first control unit 144. Is done.
　また、第１制御部１４４は、有効な押し込み操作がされていると判定した時点で、第２制御部１４６を通じて第２告知部１５０で振動を発生させる制御を行う。当該構成のスイッチ７は、操作感触がなく、しかも押し込み距離が小さいため、操作者に第２告知部１５０による振動を感触的に与えるようにしている。つまり、操作者は、指に振動を得ることによって、有効な押し込み状態であることを確認できる。 In addition, the first control unit 144 performs control to cause the second notification unit 150 to generate vibration through the second control unit 146 when it is determined that an effective pushing operation is performed. The switch 7 having such a configuration has no operational feeling and has a small push-in distance, so that the vibration by the second notification unit 150 is given to the operator. That is, the operator can confirm that the finger is in an effective push-in state by obtaining vibration on the finger.
　なお、押し込み操作の告知は、第２告知部１５０で振動を発生させる代わりに第１告知部１４８で行ってもよい。第１告知部１４８のＬＥＤで告知させる場合には、有効なタッチ操作状態での告知とは異なる点滅状態などにするとよい。または、第１告知部１４８および第２告知部１５０から共に告知がされるようにしてもよい。 Note that the notification of the push-in operation may be performed by the first notification unit 148 instead of causing the second notification unit 150 to generate vibration. When the LED of the first notification unit 148 is used for notification, a blinking state or the like different from the notification in the effective touch operation state may be set. Alternatively, both the first notification unit 148 and the second notification unit 150 may be notified.
　なお、上述説明では、有効なタッチ操作がされていると判定した際に第１告知部１４８の点灯で告知するとしたが、タッチ操作の告知に第２告知部１５０による振動を発生させてもよい。または、第２告知部１５０の振動のみで告知してもよい。 In the above description, the first notification unit 148 is turned on when it is determined that an effective touch operation is performed. However, the second notification unit 150 may generate vibration for the touch operation notification. . Or you may notify only by the vibration of the 2nd notification part 150. FIG.
　以上に説明したように、スイッチ７は、薄型構成で、タッチ操作状態および押し込み操作状態の二種類の検出が可能なものとして提供することができる。 As described above, the switch 7 can be provided with a thin configuration and capable of two types of detection: a touch operation state and a push-in operation state.
　なお、第１告知部１４８および第２告知部１５０は、第１制御部１４４および第２制御部１４６による制御で、スイッチへのタッチ操作時と押し込み操作時とで異なる告知をしてもよい。 In addition, the 1st notification part 148 and the 2nd notification part 150 may perform different notification by the time of the touch operation to a switch, and the time of pushing operation by control by the 1st control part 144 and the 2nd control part 146.
　つまり、告知部（第１告知部１４８、第２告知部１５０）は、スイッチ７へのタッチ操作時と押し込み操作時とで異なる告知をするように制御部（第１制御部１４４、第２制御部１４６）により制御されても良い。 That is, the notification unit (the first notification unit 148, the second notification unit 150) controls the control unit (the first control unit 144, the second control) so that different notifications are made when the switch 7 is touched and when the switch 7 is pressed. Part 146).
　なお、本実施の形態では、スイッチ７を二つ設けたスイッチユニット３について説明した。スイッチユニット３は一つのスイッチ７のみを有する構成にしたり、三つ以上のスイッチ７を有する構成にしたりしてもよい。 In the present embodiment, the switch unit 3 provided with two switches 7 has been described. The switch unit 3 may be configured to include only one switch 7 or may be configured to include three or more switches 7.
　なお、スイッチ７は、タッチ操作および押し込み操作共に有効な操作状態になっているか否かが操作者にとって操作中に判り難い。このため、スイッチ７の搭載時には、入力装置１００のように、スイッチ７へのそれぞれの有効な操作状態になったことが検出された折に、第１告知部１４８や第２告知部１５０を連動して作動させる構成にすると操作者が使い易くなり好ましい。 Note that it is difficult for the operator to determine whether the switch 7 is in an effective operation state for both the touch operation and the push-in operation. For this reason, when the switch 7 is mounted, the first notification unit 148 and the second notification unit 150 are interlocked with each other when it is detected that each switch 7 is in an effective operation state, like the input device 100. Therefore, it is preferable that the operation is easy to use for the operator.
　そして、このスイッチ７や入力装置１００は各種電子機器に適用可能である。スイッチ７へのタッチ操作が予告操作としてなり、押し込み操作によって、予告操作された機能の決定操作がなされるものであれば、タッチ操作のみを行って、その指を離す動作を繰り返し行っても誤操作状態になることがない。例えば、自動車の車両内に配された電子機器などに適用すると有用である。 The switch 7 and the input device 100 can be applied to various electronic devices. If the touch operation on the switch 7 becomes a notice operation, and the push-down operation determines the function of the notice operation, even if the touch operation is performed and the finger is released repeatedly, an erroneous operation is performed. There is no state. For example, it is useful when applied to an electronic device or the like arranged in a vehicle of an automobile.
　また、機器の構成要素として表示部を有するものでは、スイッチ７への有効な操作状態となった折に、表示部内での表示で告知するようにしてもよい。 Further, in the case of a device having a display unit as a component of the device, it may be notified by a display in the display unit when an effective operation state for the switch 7 is reached.
　なお、上記には、入力装置１００としてスイッチ７への有効な操作状態を検出する第１制御部１４４を内蔵させたものを説明したが、第１制御部１４４は内蔵させる必要はなく、外部に配設されていてもよい。また、入力装置１００の各種構成部材についても上述した形状等に限定されることはない。 In the above description, the first control unit 144 that detects an effective operation state of the switch 7 as the input device 100 has been described. However, the first control unit 144 does not need to be built in and is externally provided. It may be arranged. Further, the various components of the input device 100 are not limited to the above-described shapes.
　スイッチ７についても、上記では第１電極部４１および第２電極部５２をいずれも第１電極シート１１の下面側および第２電極シート２２の下面側に構成している。これらの両方またはいずれか一方が上面側に構成されていてもよい。なお、第２電極部５２を上面側に設ける場合には、第２電極シート２２の第２基材２２Ａはフィルム状以外の部材を用いることも可能である。 Also for the switch 7, the first electrode portion 41 and the second electrode portion 52 are both configured on the lower surface side of the first electrode sheet 11 and the lower surface side of the second electrode sheet 22. Both or any one of these may be configured on the upper surface side. In addition, when providing the 2nd electrode part 52 in an upper surface side, it is also possible to use members other than a film form for the 2nd base material 22A of the 2nd electrode sheet 22. FIG.
　なお、スイッチ７は、押し込み操作中に所謂アナログ的に変化する状態を含めて検出するようにしてもよい。つまり、押し込み操作によって生じた第１電極部４１と第２電極部５２との間の静電容量の変化を第１制御部１４４によって多段的に検出してもよい。 Note that the switch 7 may detect a state including a so-called analog change state during the push-in operation. That is, the change in capacitance between the first electrode unit 41 and the second electrode unit 52 caused by the pushing operation may be detected in multiple stages by the first control unit 144.
　これによれば、押し込み操作による操作者の押圧力の大きさに応じて、例えば音量の調整スピードをアナログ的に変化させる、電気ポットなどの湯量調節に用いるなど、押圧力に応じた電子機器の様々な機能の操作が行われるものに構成できる。 According to this, in accordance with the magnitude of the pressing force of the operator by the pushing operation, for example, the adjustment speed of the volume is changed in an analog manner, or used for adjusting the amount of hot water such as an electric pot, etc. It can be configured to operate various functions.
　本開示によるスイッチおよびそれを用いた入力装置は、誤操作の発生を低減できる。主に各種電子機器の入力操作部用等に有用である。 The switch according to the present disclosure and the input device using the switch can reduce the occurrence of erroneous operations. It is useful mainly for input operation sections of various electronic devices.
