Description

本発明は、スイッチや可変抵抗器等に用いられる電子部品に関し、特に外部から侵入してくる静電気が内部の電気回路に侵入するのを防止できる静電気侵入防止機能付きの電子部品に関するものである。 The present invention relates to an electronic component used for a switch, a variable resistor, or the like, and more particularly to an electronic component with an anti-electrostatic intrusion function that can prevent static intrusion from the outside from entering an internal electric circuit.

従来、例えば回転式電子部品は、操作つまみを回転することでこれと一体に回転型物を回転し、回転型物に取り付けている摺動子をこれに対向する位置に設置した基板上に設けた摺接パターンに摺接することでその電気的出力を変化するように構成されている（例えば特許文献１）。また回転式電子部品の中には、操作つまみを回転した際にクリック感覚を生じさせるクリック機構を備えたものもある。 Conventionally, for example, a rotary electronic component rotates a rotary object integrally with it by rotating an operation knob, and a slider attached to the rotary mold is provided on a substrate installed at a position opposite to this. The electric output is changed by sliding on the sliding contact pattern (for example, Patent Document 1). Some rotary electronic components include a click mechanism that generates a click sensation when the operation knob is rotated.

しかしながら上記従来の回転式電子部品においては、操作つまみに帯電した人の指等が触れると、その静電気が、操作つまみの上部からその沿面を通して回転式電子部品内部に侵入し、その摺動子や摺接パターンに入射してしまうという問題があった。 However, in the conventional rotary electronic component, when a charged human finger or the like touches the operation knob, the static electricity enters the rotary electronic component from the top of the operation knob through the creepage, and the slider or There was a problem that the light was incident on the sliding contact pattern.

特にリング形状の操作つまみの中央の穴に押釦スイッチの押釦つまみを挿入・配置した構造の押釦スイッチ付き回転式電子部品（例えば特許文献１）の場合、前記操作つまみの穴と押釦つまみの間の隙間から静電気が侵入してしまう。 In particular, in the case of a rotary electronic component with a pushbutton switch having a structure in which the pushbutton knob of the pushbutton switch is inserted and arranged in the center hole of the ring-shaped operation knob (for example, Patent Document 1), the gap between the hole of the operation knob and the pushbutton knob is Static electricity enters through the gap.

さらに近年、操作つまみに高級感を持たせる等の目的で、操作つまみ表面をメッキなどによって金属光沢を持たせる場合が増えている。しかしながら操作つまみをメッキなどの導電性部材で装飾すると、より静電気が操作つまみに侵入し易くなり、同時に導電性部材がその下側に設置した回転式電子部品の各構成部品へ静電気を導く導電通路となってしまい、より静電気による弊害を招く恐れがあった。
特開２００４−４７４９１号公報 Furthermore, in recent years, there is an increasing number of cases where the surface of the operation knob is given a metallic luster by plating or the like for the purpose of giving the operation knob a high-class feeling. However, if the operation knob is decorated with a conductive member such as plating, static electricity can easily enter the operation knob, and at the same time, the conductive member conducts static electricity to each component of the rotary electronic component installed underneath it. As a result, there was a risk of causing adverse effects due to static electricity.

[First Embodiment]
FIG. 1 is a schematic cross-sectional view of an electronic component (hereinafter referred to as “rotary electronic component”) 1-1 according to the first embodiment of the present invention (for convenience of explanation, the cross-sectional positions of the respective parts are different), FIG. FIG. 3 is an exploded perspective view of the rotary electronic component 1-1. In FIG. 1, there is a gap corresponding to the thickness of the ground pattern 183 between the base 190 and the third substrate unit 140 and between the fourth substrate unit 150 and the fifth substrate unit 160 for convenience of illustration. In practice, the ground pattern 183 is thin and has no gap.

両図に示すように回転式電子部品１−１は、操作つまみ１０と、操作つまみ１０の中央に設置される押釦つまみ３０と、操作つまみ１０の下部に設置される固定側部材であるケース４０と、ケース４０の下部に設置されて操作つまみ１０と一体に移動する移動部材（以下「回転型物」という）５０と、回転型物５０の上面側（操作つまみ１０側）に設置されて前記回転型物５０を移動する際にクリック感触を生じるクリック機構８０と、回転型物５０の下面側に設置される基板群１００と、基板群１００の下部に設置される取付部材（以下「取付板」という）２００とを具備して構成されている。以下各構成部品について説明する。 As shown in both figures, the rotary electronic component 1-1 includes an operation knob 10, a push button knob 30 installed at the center of the operation knob 10, and a case 40 which is a fixed side member installed at the lower part of the operation knob 10. And a moving member (hereinafter referred to as “rotary type”) 50 that is installed at the bottom of the case 40 and moves integrally with the operation knob 10, and is installed on the upper surface side (operation knob 10 side) of the rotary type 50.

Each component will be described below.

図３は回転式電子部品１−１を構成する各部品の内の基板群１００と取付板２００とを除く他の各部品の分解斜視図である。また図４は操作つまみ１０を裏面側から見た斜視図である。図１，図３，図４に示すように操作つまみ１０は合成樹脂製であり、略円板状の上面部１１の外周に下方に向かって突出する略円筒状の側壁部１３を設け、また上面部１１の中央に円形の上下に貫通する挿通部１５を設けて構成されている。上面部１１の下面側の前記挿通部１５の周囲部分には円筒状に突出する軸部１７が設けられ、軸部１７の下端辺からは複数本（３本）の突起部１９が突出している。軸部１７の内径は挿通部１５の内径よりも少し大きく、これによって両者の接合部分にはリング状の段部２１が形成されている。ところでこの操作つまみ１０は図１に示すように、上面部１１と側壁部１３とを構成する合成樹脂材料ａと、軸部１７と上面部１１の下面を覆う下面部２３とを構成する合成樹脂材料ｂとを異なる材料で構成してなる二材成形品である。二材成形品とは、金型内で一方の合成樹脂材を成形した後、金型内に前記成形品を残したまま金型の一部を取り換えてさらに他方の合成樹脂を成形し、これによって両合成樹脂を一体にした成形品を得る方法である。この方法によれば、両合成樹脂の接合面に全く隙間は生じず、この接合面に静電気が侵入する恐れはない。このようにこの実施形態において操作つまみ１０を二材成形品で構成したのは、上面部１１と側壁部１３のみに金属メッキを施し、軸部１７と下面部２３には金属メッキを施さないようにするためである。即ちこの実施形態においては、操作つまみ１０の上面部１１と側壁部１３を構成する合成樹脂材料ａとしてＡＢＳ樹脂を用い、軸部１７及び下面部２３を構成する合成樹脂材料ｂとしてポリカーボネート樹脂を用いている。そしてこの操作つまみ１０全体を金属メッキすると、メッキし易い合成樹脂材料（この実施形態ではＡＢＳ樹脂）ａの露出している表面のみにメッキが付着し、メッキし難い合成樹脂材料（この実施形態ではポリカーボネート樹脂）ｂの露出している表面にはメッキは付着しない（又は付着したメッキが容易に除去できる）。つまりこの実施形態においては、上面部１１と側壁部１３の露出表面のみに金属光沢を有する金属メッキが施されている。 FIG. 3 is an exploded perspective view of other components excluding the substrate group 100 and the mounting plate 200 among the components constituting the rotary electronic component 1-1.

The inner diameter of the shaft portion 17 is slightly larger than the inner diameter of the insertion portion 15, whereby a ring-shaped step portion 21 is formed at the joint portion between the two. By the way, as shown in FIG. 1, the operation knob 10 has a synthetic resin material a that forms the upper surface portion 11 and the side wall portion 13, and a synthetic resin that forms the shaft portion 17 and the lower surface portion 23 that covers the lower surface of the upper surface portion 11. It is a two-material molded product made of a material different from the material b. A two-material molded product is a product in which one synthetic resin material is molded in a mold and then a part of the mold is replaced while the molded product remains in the mold. This is a method for obtaining a molded product in which both synthetic resins are integrated. According to this method, there is no gap at all between the joint surfaces of the two synthetic resins, and there is no risk of static electricity entering the joint surfaces. Thus, in this embodiment, the operation knob 10 is formed of a two-material molded product so that only the upper surface portion 11 and the side wall portion 13 are subjected to metal plating, and the shaft portion 17 and the lower surface portion 23 are not subjected to metal plating. It is to make it. That is, in this embodiment, ABS resin is used as the synthetic resin material a constituting the upper surface portion 11 and the side wall portion 13 of the operation knob 10, and polycarbonate resin is used as the synthetic resin material b constituting the shaft portion 17 and the lower surface portion 23. ing. When the entire operation knob 10 is metal-plated, the plating adheres only to the exposed surface of the synthetic resin material (in this embodiment, ABS resin) a that is easy to plate, and the synthetic resin material (in this embodiment) that is difficult to plate. No plating adheres to the exposed surface of (polycarbonate resin) b (or the attached plating can be easily removed). That is, in this embodiment, only the exposed surfaces of the upper surface portion 11 and the side wall portion 13 are subjected to metal plating having a metallic luster.

以上のようにして組み立てられた回転式電子部品１−１は図１に示すように、操作つまみ１０と、操作つまみ１０の下部に設置されて操作つまみ１０と一体に移動（回転）する回転型物５０と、回転型物５０の上面側に設置されて回転型物５０を回転する際にクリック感触を生じるクリック機構８０と、回転型物５０の下面側に設置されて回転型物５０の回転によって電気的出力を変化する摺動子６０及び摺接パターン１３７からなる電気的機能部と、を具備し、クリック機構８０を構成するクリック板９１に回転型物５０を通して回転型物５０の下面側に露出されるアースリード部９７を設けるとともに、アースリード部９７に接近してアースパターン１８０を設置して構成されている。またクリック機構８０は、弾接部８９を設けてなるクリックバネ８１と、クリックバネ８１の弾接部８９を係合離脱することでクリック感触を生じるクリック係合部９３を有するクリック板９１とで構成され、クリック板９１は金属製であって回転型物５０に取り付けられ、回転型物５０に取り付けたクリック板９１の一部に前記アースリード部９７が設けられている。また摺接パターン１３７とアースパターン１８０は、１枚のフレキシブル回路基板１１０に形成されている。またアースパターン１８０及びアースリード部９７は、摺接パターン１３７及び摺動子６１の設置位置よりも回転型物５０の回転中心軸側に設置されている。またフレキシブル回路基板１１０は、少なくともアースパターン１８０を形成してなる第１基板部１２０と、摺接パターン１３７を形成してなる第２基板部１３０とを具備し、第２基板部１３０の摺接パターン１３７を設けた面の裏面側に第１基板部１２０を設置すると共に、第２基板部１３０に設けた開口１３１内に前記第１基板部１２０のアースパターン１８０を露出している。 As shown in FIG. 1, the rotary electronic component 1-1 assembled as described above is installed on the operation knob 10 and below the operation knob 10 and moves (rotates) integrally with the operation knob 10. An object 50, a click mechanism 80 that is installed on the upper surface side of the rotary mold 50 and produces a click feeling when the rotary mold 50 is rotated, and a rotary mechanism 50 that is installed on the lower surface side of the rotary mold 50 and rotates. And an electrical function unit composed of a sliding contact pattern 137 that changes the electrical output in accordance with the slidable contact pattern 137, and the bottom surface side of the rotary mold 50 passes through the rotary mold 50 through the click plate 91 constituting the click mechanism 80. The ground lead portion 97 exposed to the ground lead portion 97 is provided, and the ground pattern 180 is provided close to the ground lead portion 97. The click mechanism 80 includes a click spring 81 provided with an elastic contact portion 89 and a click plate 91 having a click engagement portion 93 that generates a click feeling by disengaging the elastic contact portion 89 of the click spring 81. The click plate 91 is made of metal and attached to the rotary mold 50, and the ground lead portion 97 is provided on a part of the click plate 91 attached to the rotary mold 50. The sliding contact pattern 137 and the ground pattern 180 are formed on one flexible circuit board 110. Further, the ground pattern 180 and the ground lead portion 97 are installed closer to the rotation center axis side of the rotary mold 50 than the installation positions of the sliding contact pattern 137 and the slider 61. The flexible circuit board 110 includes a first substrate part 120 formed with at least a ground pattern 180 and a second substrate part 130 formed with a slidable contact pattern 137. The first substrate unit 120 is installed on the back side of the surface on which the pattern 137 is provided, and the ground pattern 180 of the first substrate unit 120 is exposed in the opening 131 provided in the second substrate unit 130.

そして上記回転式電子部品１−１において、操作つまみ１０を回転すれば、これと一体に回転型物５０が回転し、摺動子６０の摺動冊子６３が摺接パターン１３７上を摺動してその電気的出力を変化する。一方押釦つまみ３０を押圧すれば押圧部３５が押圧スイッチ１５１を押圧して反転板１５１ｃを反転しこれをオンする。押釦つまみ３０への押圧を解除すれば反転板１５１ｃは元の形状に自動復帰し押圧スイッチ１５１はオフする。 In the rotary electronic component 1-1, when the operation knob 10 is rotated, the rotary object 50 rotates integrally therewith, and the sliding booklet 63 of the slider 60 slides on the sliding contact pattern 137. Change its electrical output. On the other hand, when the push button knob 30 is pressed, the pressing portion 35 presses the pressing switch 151 to reverse the reversing plate 151c and turn it on. When the pressing on the push button knob 30 is released, the reversing plate 151c automatically returns to its original shape and the pressing switch 151 is turned off.

一方、操作つまみ１０や押釦つまみ３０を操作する指等が帯電していた場合、操作つまみ１０表面には導電性の金属メッキが施されているので、その静電気の多くは操作つまみ１０の表面に入射し、操作つまみ１０のメッキが施されている表面を伝ってケース４０の開口部４７から回転型物５０の上面側に侵入する。そして回転型物５０の上面側に侵入した静電気は金属板製のクリックバネ８１又はクリック板９１に入射し（なおクリックバネ８１に入射した静電気はこれと接しているクリック板９１に導かれる）、クリック板９１に設けたアースリード部９７の先端からこれに接近して配置されているアースパターン１８０に放電され、アースされる。すなわちクリック機構８０に入射した静電気はアースリード部９７を通してアースパターン１８０に導かれる。従って操作つまみ１０や押釦つまみ３０から回転型物５０の上面側に入射した静電気が回転型物５０の下面側に設置した電気的機能部である摺動子６０や摺接パターン１３７やその他の回路パターンに入射することはなく、効果的に静電気の電気回路への侵入を防止できる。 On the other hand, when a finger or the like for operating the operation knob 10 or the push button knob 30 is charged, the surface of the operation knob 10 is subjected to conductive metal plating. The incident light enters the surface of the operation knob 10 plated and enters the upper surface side of the rotary mold 50 from the opening 47 of the case 40. Then, the static electricity that has entered the upper surface side of the rotary mold 50 enters the click spring 81 or the click plate 91 made of a metal plate (note that the static electricity that has entered the click spring 81 is guided to the click plate 91 in contact therewith). The tip of the earth lead portion 97 provided on the click plate 91 is discharged from the tip of the earth pattern 180 disposed close to the earth lead portion 97 and grounded. That is, the static electricity incident on the click mechanism 80 is guided to the ground pattern 180 through the ground lead portion 97. Accordingly, the static electricity incident on the upper surface side of the rotary mold 50 from the operation knob 10 or the push button knob 30 is an electrical functional unit installed on the lower surface side of the rotary mold 50, the slider 60, the sliding pattern 137, and other circuits. It does not enter the pattern and can effectively prevent static electricity from entering the electric circuit.

なおこの実施形態では操作つまみ１０の軸部１７表面にメッキを行なわず、従って前記メッキ内を導通する静電気が軸部１７にまで至らないようにしており、これによって軸部１７を回転型物５０に固定するために設けた突起部挿通部５５を通してその下面側に静電気が侵入しないようにしている（静電気はその上にあるクリック板９１に確実に捉えられる）。またこの実施形態の場合、静電気を導入するアースパターン１８０が摺接パターン１３７を形成した第２基板部１３０とは異なる第１基板部１２０に設けられているので、両パターンが同一の面上にある場合に生じる恐れのある両者間の放電も確実に防止できる。なおこの実施形態では第１基板部１２０と第２基板部１３０は同一のフレキシブル回路基板１１０であるが、摺接パターン１３７とアースパターン１８０とはフレキシブル回路基板１１０の上下の異なる面に設けられているので、この点からも両者間で放電は生じない。またこの実施形態の場合、アースパターン１８０及びアースリード部９７は、摺接パターン１３７及び摺動子６０の設置位置よりも回転型物５０の回転中心軸側に設置されているが、これは回転式電子部品１−１の電気的機能部である摺接パターン１３７及び摺動子６０の回転中心軸側に形成される使用されていないスペースを利用してアースパターン１８０及びアースリード部９７を設置したものであり、このためアースパターン１８０及びアースリード部９７による静電気侵入防止機構を回転式電子部品１−１に設置してもこの回転式電子部品１−１が大型化することはなく、この静電気侵入防止機構を容易に設置することができる。 In this embodiment, the surface of the shaft portion 17 of the operation knob 10 is not plated, so that static electricity conducted through the plating does not reach the shaft portion 17. Static electricity does not enter the lower surface side through the protrusion insertion portion 55 provided for fixing to the metal plate (static electricity is reliably captured by the click plate 91 thereabove). In the case of this embodiment, since the ground pattern 180 for introducing static electricity is provided on the first substrate portion 120 different from the second substrate portion 130 on which the sliding contact pattern 137 is formed, both patterns are on the same surface. It is possible to reliably prevent discharge between the two that may occur in some cases. In this embodiment, the first board portion 120 and the second board portion 130 are the same flexible circuit board 110, but the sliding contact pattern 137 and the ground pattern 180 are provided on different upper and lower surfaces of the flexible circuit board 110. Therefore, no discharge occurs between these two points. In the case of this embodiment, the ground pattern 180 and the ground lead portion 97 are installed closer to the rotation center axis side of the rotary object 50 than the positions where the sliding contact pattern 137 and the slider 60 are installed. The ground pattern 180 and the ground lead portion 97 are installed using the unused space formed on the rotation center axis side of the sliding element 60 and the sliding contact pattern 137 which is an electrical function portion of the electronic component 1-1. For this reason, even if the electrostatic intrusion prevention mechanism by the ground pattern 180 and the ground lead portion 97 is installed in the rotary electronic component 1-1, the rotary electronic component 1-1 is not enlarged. An electrostatic intrusion prevention mechanism can be easily installed.

〔第２実施形態〕
図８は本発明の第２実施形態にかかる電子部品（以下「回転式電子部品」という）１−２の概略断面図（説明の都合上、各部の断面位置は異なっている。）である。同図に示す回転式電子部品１−２において、前記第１実施形態にかかる回転式電子部品１−１と同一又は相当部分には同一符号を付す。なお以下で説明する事項以外の事項については、前記第１実施形態にかかる回転式電子部品１−１と同じである。 [Second Embodiment]
FIG. 8 is a schematic cross-sectional view of an electronic component (hereinafter referred to as “rotary electronic component”) 1-2 according to the second embodiment of the present invention (for convenience of description, the cross-sectional position of each part is different). In the rotary electronic component 1-2 shown in the figure, the same or corresponding parts as those of the rotary electronic component 1-1 according to the first embodiment are denoted by the same reference numerals. Note that items other than those described below are the same as those of the rotary electronic component 1-1 according to the first embodiment.

この実施形態において第１実施形態と相違する点は、基板群１００の内の第１基板部１２０を省略し、その代りに第１基板部１２０に設けていたアースパターン１８０を第２基板部１３０の摺接パターン１３７を設けた側の面の開口１３１の周囲にリング状に形成した点のみである。この実施形態の場合、開口１３１の内径を小さくし、押圧部３５の外周面に接近させている。このように構成してもアースリード部９７に接近又は当接してアースパターン１８０を設置することができ、第１実施形態と同様に操作つまみ１０側から侵入する静電気を効果的に除去することができる。なおこの実施形態の場合、アースパターン１８０と摺接パターン１３７とを同一基板の表面に設けることとなるが、両者間の間隔をある程度大きく取れば放電の問題はない。 This embodiment is different from the first embodiment in that the first substrate portion 120 in the substrate group 100 is omitted, and instead the ground pattern 180 provided on the first substrate portion 120 is replaced with the second substrate portion 130. This is only a point formed in a ring shape around the opening 131 on the surface provided with the sliding contact pattern 137. In the case of this embodiment, the inner diameter of the opening 131 is made smaller to approach the outer peripheral surface of the pressing portion 35. Even with this configuration, the ground pattern 180 can be installed in contact with or in contact with the ground lead portion 97, and static electricity entering from the operation knob 10 side can be effectively removed as in the first embodiment. it can. In the case of this embodiment, the ground pattern 180 and the sliding contact pattern 137 are provided on the surface of the same substrate, but there is no problem of discharge if the distance between the two is made large to some extent.

〔第３実施形態〕
本発明の第３実施形態にかかる回転式電子部品１−３は、図１〜図７に示す回転式電子部品１−１において、前記押釦つまみ３０の外周面の装飾をメッキ又は通常の導電性の蒸着膜によって形成したものである。従ってその説明を図１を用いて行なうと、この回転式電子部品１−３の場合、操作つまみ１０又は押釦つまみ３０に帯電した指等が接近又は触れると、操作つまみ１０だけでなく、押釦つまみ３０の押圧部３５を通して回転型物５０の下面側に静電気が侵入する。しかしながら押圧部３５の先端に侵入した静電気は反転板１５１ｃの上面が絶縁性の粘着テープ（絶縁部材）１５１ｄによって覆われていることで、押圧スイッチ１５１に侵入することはない。一方押圧部３５の外周にはこれに接近（又は接触）してアースパターン１８０が位置しているので、前記静電気はアースパターン１８０に放電され、アースされる。従って帯電した押圧部３５からみてアースパターン１８０よりも外方の位置にある電気的機能部（摺動子６０と摺接パターン１３７）に押圧部３５の静電気が放電することはない（さらに開口１３１の内径を押圧部挿通穴１２１の内径より大きくすることでも、摺接パターン１３７への静電気の侵入を防止している）。従って例え押釦つまみ３０の表面に金属メッキ等による導電層を設けている場合であっても、この導電層に侵入した静電気が電気的機能部に侵入することはない。 [Third Embodiment]
The rotary electronic component 1-3 according to the third embodiment of the present invention is the same as the rotary electronic component 1-1 shown in FIGS. It is formed by the vapor deposition film. Therefore, the description will be made with reference to FIG. 1. In the case of the rotary electronic component 1-3, when a charged finger or the like approaches or touches the operation knob 10 or the push button knob 30, not only the operation knob 10 but also the push button knob. Static electricity enters the lower surface side of the rotary mold 50 through the 30 pressing portions 35. However, the static electricity that has entered the tip of the pressing portion 35 does not enter the pressing switch 151 because the upper surface of the reversing plate 151c is covered with the insulating adhesive tape (insulating member) 151d. On the other hand, since the ground pattern 180 is located on the outer periphery of the pressing portion 35 so as to approach (or contact) the static electricity, the static electricity is discharged to the ground pattern 180 and grounded. Accordingly, the static electricity of the pressing portion 35 is not discharged to the electrical function portion (slider 60 and sliding contact pattern 137) located outside the ground pattern 180 when viewed from the charged pressing portion 35 (further, the opening 131). Is also made larger than the inner diameter of the pressing portion insertion hole 121 to prevent static electricity from entering the sliding contact pattern 137). Therefore, even if a conductive layer made of metal plating or the like is provided on the surface of the push button knob 30, static electricity that has entered the conductive layer does not enter the electrical function unit.

即ちこの実施形態には、押圧スイッチ１５１（スイッチ接点１５１ａ，１５１ｂ）と、押圧スイッチ１５１上に設置されてこの押圧スイッチ１５１を押圧する押圧部３５を有する押釦つまみ３０と、押釦つまみ３０の押圧部３５近傍又は押圧部３５に接する位置にアースパターン１８０を形成してなるアースパターン形成部材（この実施形態では第１基板部１２０）と、を具備する押釦つまみのアース構造が開示されており、さらに、押釦つまみ３０の押圧部３５が、アースパターン形成部材（第１基板部１２０）のアースパターン１８０を設けた部分に設けた押圧部挿通穴１２１を貫通している構成が開示されており、またアースパターン形成部材（第１基板部１２０）の上部に機能パターン形成部材（この実施形態では機能パターンである摺接パターン１３７を設けた第２基板部１３０）を設置し、この機能パターン形成部材（第２基板部１３０）に押圧部３５の外径よりも所定寸法大きい内径の開口１３１を設けて前記押圧部３５を通す構成が開示されている。なお同様に、第２実施形態の押釦つまみ３０の外周面の装飾を金属メッキ等の導電層で行なっても良い。 That is, in this embodiment, a push switch 151 (switch contacts 151 a and 151 b), a push button knob 30 having a push portion 35 installed on the push switch 151 and pushing the push switch 151, and a push portion of the push button knob 30 are included. 35, a ground pattern forming member (in this embodiment, the first substrate portion 120) formed by forming a ground pattern 180 in the vicinity of the pressing portion 35 or a position in contact with the pressing portion 35 is disclosed. In addition, a configuration is disclosed in which the pressing portion 35 of the pushbutton knob 30 passes through a pressing portion insertion hole 121 provided in a portion where the ground pattern 180 of the ground pattern forming member (first substrate portion 120) is provided, and A functional pattern forming member (in this embodiment, a functional pattern) is formed on the ground pattern forming member (first substrate portion 120). The second substrate portion 130) provided with the sliding contact pattern 137 is installed, and the opening 131 having an inner diameter larger than the outer diameter of the pressing portion 35 by a predetermined dimension is provided in the functional pattern forming member (second substrate portion 130). The structure which lets the part 35 pass is disclosed. Similarly, the outer peripheral surface of the push button knob 30 of the second embodiment may be decorated with a conductive layer such as metal plating.

なお上記各実施形態では操作つまみ１０及び／又は押釦つまみ３０の表面にメッキなどによる導電層が形成されている場合について説明したが、本発明は必ずしも操作つまみ１０や押釦つまみ３０にメッキ等の導電層が施されていない場合でも適用できる。導電層がなくても静電気は沿面放電によって回転型物５０の下面側に侵入するからである。 In each of the above embodiments, the case where a conductive layer by plating or the like is formed on the surface of the operation knob 10 and / or the push button knob 30 has been described. However, the present invention does not necessarily require that the operation knob 10 or the push button knob 30 be electrically conductive such as plating. Applicable even when the layer is not applied. This is because even if there is no conductive layer, static electricity enters the lower surface side of the rotary mold 50 by creeping discharge.

以上本発明の実施形態を説明したが、本発明は上記実施形態に限定されるものではなく、特許請求の範囲、及び明細書と図面に記載された技術的思想の範囲内において種々の変形が可能である。なお直接明細書及び図面に記載のない何れの形状・構造・材質であっても、本願発明の作用・効果を奏する以上、本願発明の技術的思想の範囲内である。例えば上記実施形態においては、本発明を回転式電子部品に利用した場合を説明したが、本発明はスライド式電子部品等の他の電子部品にも利用することができる。またクリック機構の構造も上記実施形態には限定されず、種々の変形が可能であり、要は移動部材の上面側に設置されて移動部材を移動する際にクリック感触を生じるクリック機構であればどのような構造であっても良い。また上記実施形態では摺動子６０と摺接パターン１３７とによって電気的機能部を構成したが、電気的機能部の構造も種々の変形が可能であることはいうまでもなく、要は移動部材の下面側に設置されて移動部材の移動によって電気的出力を変化する電気的機能部であればどのような構造であっても良い。アースリード部９７の形状、構造も種々の変形が可能であり、要は移動部材を通して移動部材の下面側に露出されるアースリード部であればどのような構造であってもよい。また上記実施形態ではアースリード部９７の先端をアースパターン１８０に接近させて設置し、静電気は両者間の放電によって行うように構成したが、これはアースリード部９７をアースパターン１８０に当接するとアースパターン１８０が磨耗したり回転型物５０の回転に抵抗を生じたりする不都合を考慮したものであり、このような不都合がない（又は不都合が無視できる）場合はアースリード部９７をアースパターン１８０表面に当接しても良い。また上記実施形態では回転型物５０にクリック板９１を取り付け、固定側部材であるケース４０にクリックバネ８１を取り付けたが、逆に回転型物５０にクリックバネ８１を取り付け、固定側部材にクリック板９１を取り付けても良い。その場合、クリックバネ８１にアースリード部９７を設ける。またクリック機構は少なくとも回転型物５０に取り付けられる部材であるクリック板９１又はクリックバネ８１（アースリード部９７を設けた側の部材）を金属製として導電性を持たせれば良い（もちろん両者に導電性を持たせた方がより静電気の侵入防止に効果的であることはいうまでもない）。またアースリード部９７はこれを設けるクリック板９１やクリックバネ８１と必ずしも一体品でなくてもよく、別部品としてクリック板９１やクリックバネ８１に導電性のアースリード部９７を取り付けても良い。また本発明は少なくともアースリード部９７に導電性があれば良い。また上記実施形態のようにアースリード部９７を金属製としてそれ自体に導電性を持たせても良いし、その表面に導電層を設けることで導電性を持たせても良い。また上記実施形態ではアース部材としてアースパターン１８０を用いたが、金属板など、アースパターン以外の各種アース部材であっても良い。さらに上記実施形態では１枚のフレキシブル回路基板に摺接パターン１３７とアースパターン１８０とを形成した（両者がフレキシブル回路基板の上下異なる面に形成される場合も同一面に形成される場合もある）が、別々の回路基板に両者を形成しても良い。なお回路基板は硬質基板であっても良い。 Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings. Is possible. It should be noted that any shape, structure, and material not directly described in the specification and drawings are within the scope of the technical idea of the present invention as long as the effects and advantages of the present invention are exhibited. For example, in the above embodiment, the case where the present invention is used for a rotary electronic component has been described. However, the present invention can also be used for other electronic components such as a slide electronic component. Also, the structure of the click mechanism is not limited to the above embodiment, and various modifications are possible. In short, any click mechanism that is installed on the upper surface side of the moving member and generates a click feeling when moving the moving member. Any structure may be used. In the above embodiment, the electrical function unit is configured by the slider 60 and the sliding contact pattern 137, but it goes without saying that the structure of the electrical function unit can be variously modified. Any structure may be used as long as it is an electrical function unit that is installed on the lower surface side of the plate and changes the electrical output by the movement of the moving member. The shape and structure of the ground lead portion 97 can be variously modified. In short, any structure may be used as long as the ground lead portion is exposed to the lower surface side of the moving member through the moving member. Further, in the above embodiment, the tip of the ground lead portion 97 is installed close to the ground pattern 180, and the static electricity is configured to be discharged by discharging between them. However, this is because the ground lead portion 97 is brought into contact with the ground pattern 180. This is in consideration of inconvenience that the ground pattern 180 is worn out or resists rotation of the rotary mold 50, and when there is no such inconvenience (or the inconvenience can be ignored), the earth lead portion 97 is connected to the ground pattern 180. You may contact | abut on the surface. In the above embodiment, the click plate 91 is attached to the rotary mold 50 and the click spring 81 is attached to the case 40 that is a fixed member. Conversely, the click spring 81 is attached to the rotary mold 50 and the click is fixed to the fixed member. A plate 91 may be attached. In that case, a ground lead 97 is provided on the click spring 81. Further, the click mechanism may be made of metal by making at least the click plate 91 or the click spring 81 (the member on the side provided with the earth lead portion 97), which is a member attached to the rotary mold 50 (of course, both have conductivity). Needless to say, it is more effective to prevent the intrusion of static electricity. The ground lead portion 97 does not necessarily have to be integrated with the click plate 91 or the click spring 81 on which the ground lead portion 97 is provided, and the conductive ground lead portion 97 may be attached to the click plate 91 or the click spring 81 as a separate part. In the present invention, it is sufficient that at least the ground lead portion 97 has conductivity. Further, as in the above-described embodiment, the earth lead portion 97 may be made of metal and may have conductivity, or may be made conductive by providing a conductive layer on the surface thereof. In the above embodiment, the ground pattern 180 is used as the ground member. However, various ground members other than the ground pattern such as a metal plate may be used. Furthermore, in the above-described embodiment, the sliding contact pattern 137 and the ground pattern 180 are formed on one flexible circuit board (both may be formed on different surfaces of the flexible circuit board or may be formed on the same surface). However, both may be formed on separate circuit boards. The circuit board may be a hard board.
