Description

本発明は、接触部を有する可動電極と、接触部と接触可能な被接触部を有する固定電極とを備え、可動電極を固定電極に対して回転させたときの接触部と被接触部との導通状態に基づき、可動電極の回転情報を検出する回転形パルススイッチに関する。   The present invention includes a movable electrode having a contact portion and a fixed electrode having a contacted portion that can contact the contact portion, and the contact portion and the contacted portion when the movable electrode is rotated with respect to the fixed electrode. The present invention relates to a rotary pulse switch that detects rotation information of a movable electrode based on a conduction state.

従来、特許文献1に記載のごとく、回転中心を有し、回転中心から同一半径の位置に四つの接触部が形成された可動電極と、接触部と接触可能な複数の被接触部が、可動電極と対向する平面上、かつ、接触部の回転軌跡上に、互いに離間して配置された固定電極と、を備えた回転形パルススイッチがあった。この固定電極は、一以上の被接触部を有する第一電極パターンと、一以上の被接触部を有する第二電極パターンと、一以上の被接触部を有する共通電極パターンと、を互いに導通しない状態で備えている。また、この回転形パルススイッチは、可動電極の回転途中において、接触部が被接触部と接触することにより第一電極パターン及び第二電極パターンのうち少なくとも何れか一方と共通電極パターンとが導通する第一状態と、第一電極パターン、第二電極パターン、及び、共通電極パターンの何れもが互いに導通しない第二状態と、が発生するよう構成されている。   Conventionally, as described in Patent Document 1, a movable electrode having a rotation center and having four contact portions formed at the same radius from the rotation center and a plurality of contacted portions that can contact the contact portions are movable. There has been a rotary pulse switch that includes fixed electrodes that are spaced apart from each other on a plane facing the electrode and on a rotation locus of the contact portion. The fixed electrode does not electrically connect the first electrode pattern having one or more contacted parts, the second electrode pattern having one or more contacted parts, and the common electrode pattern having one or more contacted parts. Prepared in state. In the rotary pulse switch, the common electrode pattern is electrically connected to at least one of the first electrode pattern and the second electrode pattern when the contact portion comes into contact with the contacted portion during the rotation of the movable electrode. The first state and the second state where none of the first electrode pattern, the second electrode pattern, and the common electrode pattern are connected to each other are configured to occur.

この構成によると、第一状態においては、第一電極パターンと共通電極パターンとの導通、第一電極パターンと第二電極パターンと共通電極パターンとの導通、第二電極パターンと共通電極パターンとの導通、という可動電極を介した各電極パターンの電気的導通によってパルス波が発生する。よって、このパルス波の経時変化を監視することにより、可動電極の回転方向及び回転量を検出可能である。   According to this configuration, in the first state, conduction between the first electrode pattern and the common electrode pattern, conduction between the first electrode pattern and the second electrode pattern and the common electrode pattern, and between the second electrode pattern and the common electrode pattern A pulse wave is generated by electrical conduction of each electrode pattern through the movable electrode, which is conduction. Therefore, the rotational direction and the amount of rotation of the movable electrode can be detected by monitoring the change with time of the pulse wave.

さらに、第二状態のときに、可動電極は、固定電極を外周側から取り巻くように配設された接地電極に接触する。よって、第二状態が発生している間に、可動電極に帯電した静電気は接地されて放電される。   Further, in the second state, the movable electrode comes into contact with a ground electrode disposed so as to surround the fixed electrode from the outer peripheral side. Therefore, while the second state is occurring, static electricity charged on the movable electrode is grounded and discharged.

即ち、特許文献1に記載の技術によると、パルス波の発生に影響を与えることなく、可動電極や固定電極に電気的に接続された各種電気部品が静電破壊することを防止できる。   That is, according to the technique described in Patent Document 1, it is possible to prevent electrostatic breakdown of various electrical components electrically connected to the movable electrode and the fixed electrode without affecting the generation of pulse waves.

しかしながら、特許文献1であると、接地電極を固定電極の周外側に配設する構成であるため、回転形パルススイッチを回転径方向に小型化し難い。   However, in Patent Document 1, since the ground electrode is disposed outside the fixed electrode, it is difficult to reduce the size of the rotary pulse switch in the radial direction.

本発明の目的は、回転径方向への小型化が可能な回転形パルススイッチを提供することにある。   An object of the present invention is to provide a rotary pulse switch that can be downsized in the radial direction.

本発明に係る回転形パルススイッチの第一特徴構成は、回転中心を有し、当該回転中心から同一半径の位置に三以上の接触部が形成された可動電極と、前記接触部と接触可能な複数の被接触部が、前記可動電極と対向する平面上、かつ、前記接触部の回転軌跡上に、互いに離間して配置された固定電極と、を備え、前記固定電極は、一以上の前記被接触部を有する第一電極パターンと、一以上の前記被接触部を有する第二電極パターンと、一以上の前記被接触部を有する共通電極パターンと、一以上の前記被接触部を有する接地電極パターンと、を互いに導通しない状態で備え、前記可動電極の回転途中において、前記接触部が前記被接触部と接触することにより前記第一電極パターン及び前記第二電極パターンのうち少なくとも何れか一方と前記共通電極パターンとが導通する第一状態と、前記第一電極パターン、前記第二電極パターン、及び、前記共通電極パターンの何れもが互いに導通せず、かつ、少なくとも一つの前記接触部が前記接地電極パターンの前記被接触部に接触する第二状態と、が発生するよう構成した点にある。   The first characteristic configuration of the rotary pulse switch according to the present invention is a movable electrode having a rotation center and having three or more contact portions formed at the same radius from the rotation center, and capable of contacting the contact portion. A plurality of contacted portions, each having a fixed electrode arranged on a plane opposite to the movable electrode and spaced apart from each other on a rotation locus of the contact portion, and the fixed electrode includes one or more of the fixed electrodes A first electrode pattern having a contacted part, a second electrode pattern having one or more contacted parts, a common electrode pattern having one or more contacted parts, and a ground having one or more contacted parts An electrode pattern in a state where they are not electrically connected to each other, and at least one of the first electrode pattern and the second electrode pattern when the contact portion comes into contact with the contacted portion during the rotation of the movable electrode None of the first state in which the common electrode pattern is electrically connected, the first electrode pattern, the second electrode pattern, and the common electrode pattern are electrically connected to each other, and at least one of the contact portions is And a second state in which the ground electrode pattern is in contact with the contacted portion.

本構成であると、可動電極の回転による第一状態と第二状態との発生に基づいて、可動電極の回転情報を検出可能としつつ、回転途中において、可動電極に帯電した静電気を接地して放電することができる。さらに、第一電極パターンと第二電極パターンと共通電極パターンと接地電極パターンとの被接触部が同一円上に配置されているため、径方向に小型化可能な回転形パルススイッチとすることができる。   With this configuration, based on the occurrence of the first state and the second state due to the rotation of the movable electrode, it is possible to detect the rotation information of the movable electrode and ground the static electricity charged on the movable electrode during the rotation. Can be discharged. Furthermore, since the contact portions of the first electrode pattern, the second electrode pattern, the common electrode pattern, and the ground electrode pattern are arranged on the same circle, a rotary pulse switch that can be reduced in the radial direction can be obtained. it can.

本発明に係る回転形パルススイッチの第二特徴構成は、前記可動電極が所定角度回転する毎に前記可動電極に回転抵抗を付与する抵抗部を備え、前記抵抗部が前記可動電極に前記回転抵抗を付与するときに前記第二状態が発生するよう前記接地電極パターンを配設した点にある。   A second characteristic configuration of the rotary pulse switch according to the present invention is provided with a resistance portion that applies a rotational resistance to the movable electrode every time the movable electrode rotates by a predetermined angle, and the resistance portion is provided on the movable electrode with the rotational resistance. The ground electrode pattern is disposed so that the second state is generated when applying.

本構成であると、所定回転ごとに可動電極に回転抵抗が付与されるため、回転操作力が除去されたとき可動電極は第二状態となって停止する。この結果、可動電極が停止したときに、可動電極に帯電した静電気は可動電極の停止時に確実に接地される。また、使用者は触覚を通じて可動電極が所定角度回転したことを体感できる。   With this configuration, rotation resistance is applied to the movable electrode at every predetermined rotation, so that when the rotational operation force is removed, the movable electrode enters the second state and stops. As a result, when the movable electrode is stopped, static electricity charged in the movable electrode is reliably grounded when the movable electrode is stopped. In addition, the user can experience that the movable electrode has rotated a predetermined angle through the sense of touch.

However, this vertical relationship does not limit the vertical relationship when the switch is used.

〔全体構成〕
スイッチは、回転操作、四方向傾動操作、及び、中心押し操作を電気的に検出可能な複合操作スイッチである。このスイッチは、例えば、携帯電話機、PDA、ゲーム機器の操作入力部や、家庭用電化製品の操作入力部等に備えられる。
〔overall structure〕
The switch is a composite operation switch that can electrically detect a rotation operation, a four-direction tilt operation, and a center push operation. This switch is provided in, for example, an operation input unit of a mobile phone, a PDA, or a game machine, or an operation input unit of a household appliance.

スイッチは、図1乃至3に示すごとく、ダイヤル1と、キートップ2と、「可動電極」としての可動電極板5と、中心操作キー6と、基板8と、を備えている。キートップ2にダイヤル1を回転操作軸L回りに回転操作可能なよう支持した状態で、キートップ2を基板8に固定してある。また、ダイヤル1は、キートップ2を介して基板8に対して平面視十字の四方向に傾動操作可能である。中心操作キー6は、基板8に対して回転中心軸Lに沿って押し操作可能なよう、ダイヤル1と基板8とで支持してある。   As shown in FIGS. 1 to 3, the switch includes a dial 1, a key top 2, a movable electrode plate 5 as a “movable electrode”, a central operation key 6, and a substrate 8. The key top 2 is fixed to the substrate 8 in a state where the dial 1 is supported on the key top 2 so as to be rotatable about the rotation operation axis L. Further, the dial 1 can be tilted and operated in four directions of a cross in plan view with respect to the substrate 8 via the key top 2. The center operation key 6 is supported by the dial 1 and the substrate 8 so as to be pressed along the rotation center axis L with respect to the substrate 8.

可動電極板5はダイヤル1に固定されており、ダイヤル1を回転操作することにより基板8に対して回転中心軸L回りに回転する。即ち、回転操作軸Lが、本発明に係る「回転中心」に相当する。基板8には、「固定電極」としての回転操作用パターン81と、四方向操作用パターン82と、中心操作用パターン83と、がプリントされている。   The movable electrode plate 5 is fixed to the dial 1, and rotates about the rotation center axis L with respect to the substrate 8 by rotating the dial 1. That is, the rotation operation axis L corresponds to the “rotation center” according to the present invention. On the substrate 8, a rotation operation pattern 81 as a “fixed electrode”, a four-direction operation pattern 82, and a center operation pattern 83 are printed.

ダイヤル1を回転操作すると、可動電極板5と回転操作用パターン81とが導通状態または非導通状態となって、パルス波が発生する。これにより、ダイヤル1の回転情報、例えば、ダイヤル1の回転方向及び回転量を検出できる。また、ダイヤル1を四方向の何れかの方向に傾動操作すると、四方向操作用パターン82が後述するスナップ板10を介して導通状態となる。これにより、ダイヤル1の傾動方向を検出できる。また、中心操作キー6を押し操作すると、中心操作用パターン83が後述するスナップ板10を介して導通状態となる。これにより、中心操作キー6の押し操作を検出できる。   When the dial 1 is rotated, the movable electrode plate 5 and the rotation operation pattern 81 are in a conductive state or a non-conductive state, and a pulse wave is generated. Thereby, the rotation information of the dial 1, for example, the rotation direction and the rotation amount of the dial 1 can be detected. Further, when the dial 1 is tilted in any one of the four directions, the four-way operation pattern 82 becomes conductive through the snap plate 10 described later. Thereby, the tilting direction of the dial 1 can be detected. Further, when the center operation key 6 is pressed, the center operation pattern 83 is brought into a conductive state via a snap plate 10 described later. Thereby, the pressing operation of the center operation key 6 can be detected.

なお、図示はしないが、スイッチは、各パターンにおける電気的導通と非導通とを検知して、各操作情報を検出する検出手段を備えている。また、各パターンと検出手段とは不図示のリード線を介して接続されている。ただし、検出手段については公知であるので、ここでは特に説明しない。   Although not shown, the switch includes detection means for detecting each operation information by detecting electrical conduction and non-conduction in each pattern. Each pattern and the detection means are connected via a lead wire (not shown). However, since the detection means is known, it will not be specifically described here.

〔ダイヤルについて〕
ダイヤル1は、図1,2に示すごとく、中心に円筒形状の貫通部11を備えたドーナツ型の樹脂製部材である。ダイヤル1には、底面を凹入した環状の凹入部12が形成してある。貫通部11と凹入部12とにより、ダイヤル1には内壁部13と外壁部14とが形成されている。貫通部11の内周面に段部13aを形成してある。段部13aは、後述する中心操作キー6の段部63と協働して、中心操作キー6が貫通部11から抜け出すことを防止するものである。内壁部13の底面から下方に向けて、ピン形状のかしめ部15を形成してある。かしめ部15は、周方向に沿って等間隔に四箇所形成してある。かしめ部15によって、可動電極板5をダイヤル1に固定する。使用者がダイヤル1を回転操作しやすいよう、ダイヤル1の上面外周に周方向に沿って等間隔毎に複数の窪みを形成してある。
[About the dial]
As shown in FIGS. 1 and 2, the dial 1 is a donut-shaped resin member having a cylindrical penetrating portion 11 at the center. The dial 1 is formed with an annular recessed portion 12 having a recessed bottom surface. An inner wall portion 13 and an outer wall portion 14 are formed on the dial 1 by the penetrating portion 11 and the recessed portion 12. A step portion 13 a is formed on the inner peripheral surface of the penetrating portion 11. The step portion 13a cooperates with a step portion 63 of the center operation key 6 described later to prevent the center operation key 6 from coming out of the penetration portion 11. A pin-shaped caulking portion 15 is formed downward from the bottom surface of the inner wall portion 13. Four caulking portions 15 are formed at equal intervals along the circumferential direction. The movable electrode plate 5 is fixed to the dial 1 by the caulking portion 15. A plurality of depressions are formed at equal intervals along the circumferential direction on the outer periphery of the upper surface of the dial 1 so that the user can easily rotate the dial 1.

〔キートップについて〕
キートップ2は、図1,2に示すごとく、基部21と感触部22と脚部23とを備えた樹脂製の部材である。基部21は、断面矩形状の環状に形成してある。脚部23は、基部21に対して90°毎に配設され、基部21を宙に浮かせた状態で下側から四箇所を支持している。感触部22は、基部21の周内に納まる位置に配設され、その下部が脚部23を介して基部21と連結されている。感触部22の中心は、ダイヤル1の内壁部13を挿入可能なよう、円筒形状に貫通してある。感触部22の外周面22aには、周方向に沿って複数の凹凸を形成してある。この凹凸は、後述する感触用バネ3のバネ部31と協働して、使用者にクリック感を与えるものである。
[About Key Top]
As shown in FIGS. 1 and 2, the key top 2 is a resin member including a base portion 21, a touch portion 22, and a leg portion 23. The base 21 is formed in an annular shape having a rectangular cross section. The leg part 23 is arrange | positioned every 90 degrees with respect to the base 21, and supports four places from lower side in the state which floated the base 21 in the air. The touch portion 22 is disposed at a position that fits within the circumference of the base portion 21, and a lower portion thereof is connected to the base portion 21 via a leg portion 23. The center of the touch part 22 penetrates in a cylindrical shape so that the inner wall part 13 of the dial 1 can be inserted. A plurality of irregularities are formed on the outer peripheral surface 22 a of the touch part 22 along the circumferential direction. The unevenness provides a click feeling to the user in cooperation with a spring portion 31 of the touch spring 3 described later.

脚部23の底面から下方に向けてピン形状のかしめ部24を立設形成してある。四箇所のかしめ部24を基板8に形成された取付用の孔に夫々挿入し、脚部23の底面が基板8に接した状態で、かしめ部24を熱かしめしてキートップ2を基板8に固定する。   A pin-shaped caulking portion 24 is formed upright from the bottom surface of the leg portion 23 downward. The four caulking portions 24 are respectively inserted into mounting holes formed in the substrate 8, and the caulking portion 24 is heat caulked in a state where the bottom surface of the leg portion 23 is in contact with the substrate 8, so that the key top 2 is attached to the substrate 8. To fix.

基部21の上面のうち、隣り合う脚部23の周方向に沿った中間位置に受圧部21aを凸設してある。即ち、受圧部21aは四箇所存在する。また、基部21の下面のうち、受圧部21aの裏側の位置に押圧部21bを凸設してある。基部21の内外周径は、受圧部21aがダイヤル1の外壁部14の底面を支持できる程度に設定してある。上述したように、基部21の断面形状が矩形状であり、かつ、脚部23同士がある程度離間しているため、受圧部21aが上方から押圧されると、基部21は脚部23を支点として下方にたわんで変形する。キートップ2は樹脂製であるため、この変形は弾性変形であり、押圧力を除去すると基部21は元の状態に戻る。このような構成により、ダイヤル1を四方向へ傾動操作することが可能である。   On the upper surface of the base portion 21, a pressure receiving portion 21 a is protruded at an intermediate position along the circumferential direction of the adjacent leg portions 23. That is, there are four pressure receiving portions 21a. In addition, a pressing portion 21b is provided on the lower surface of the base portion 21 at a position on the back side of the pressure receiving portion 21a. The inner and outer peripheral diameters of the base portion 21 are set such that the pressure receiving portion 21 a can support the bottom surface of the outer wall portion 14 of the dial 1. As described above, since the cross-sectional shape of the base portion 21 is rectangular and the leg portions 23 are spaced apart from each other to some extent, when the pressure receiving portion 21a is pressed from above, the base portion 21 uses the leg portion 23 as a fulcrum. Deforms by bending downward. Since the key top 2 is made of resin, this deformation is elastic deformation, and when the pressing force is removed, the base 21 returns to the original state. With such a configuration, the dial 1 can be tilted in four directions.

本実施形態では、四箇所の脚部23は、図1に示すごとく、周方向において、90°の均等角度ではなく、約80°、約100°、約80°、約100°の中心角をもって離間している。周方向において脚部23を均等角度90°の中心角をもって離間させると、部21の曲げ応力が同一となって好適である。しかし、基板8にプリントされたパターンの配置によっては、本実施形態のように脚部23を90°毎に均等することができない場合がある。よって、各脚部23の間において基部21の曲げ応力に差異が出ないよう、基部21の断面二次モーメントを設定する。
〔可動電極板について〕
In the present embodiment, as shown in FIG. 1, the four leg portions 23 have center angles of about 80 °, about 100 °, about 80 °, and about 100 ° in the circumferential direction instead of a uniform angle of 90 °. It is separated. It is preferable that the leg portions 23 are separated from each other with a central angle of 90 ° in the circumferential direction because the bending stress of the portion 21 is the same. However, depending on the arrangement of the patterns printed on the substrate 8, the leg portions 23 may not be equalized every 90 ° as in the present embodiment. Therefore, the cross-sectional secondary moment of the base portion 21 is set so that the bending stress of the base portion 21 is not different between the leg portions 23.
[About movable electrode plate]

可動電極板5は、図1,2に示すごとく、環状の金属製部材である。可動電極板5は、支持部51と、支持部51から切出された部分が支持部51から斜め下方に向けて屈曲されてなるブラシ部52とを有する。ブラシ部52は、周方向に沿って90°毎に四箇所形成してあり、回転中心軸Lから同一半径の位置にある。固定板4を介して支持部51をダイヤル1の外壁部14の底面に固定することによって、可動電極板5はダイヤル1に固定される。詳しく説明すると、支持部51と固定板4とに、かしめ部15に対応する取付用の孔を四箇所ずつ形成してある。かしめ部15をこれらの取付用の孔に挿入し、固定板4が外壁部14の底面に接した状態、かつ、可動電極板5が固定板4に接した状態で、かしめ部15を熱かしめする。これにより、可動電極板5がダイヤル1に固定される。ダイヤル1が回転操作されると、ブラシ部52は、その先端部を基板8上の回転操作用パターン81に接触させつつ回転中心軸Lの周りに回転する。即ち、ブラシ部52が、本発明に係る「接触部」に相当する。
〔中心操作キー・回転防止部材について〕
The movable electrode plate 5 is an annular metal member as shown in FIGS. The movable electrode plate 5 includes a support portion 51 and a brush portion 52 formed by bending a portion cut out from the support portion 51 obliquely downward from the support portion 51. The brush portions 52 are formed at four positions every 90 ° along the circumferential direction, and are located at the same radius from the rotation center axis L. The movable electrode plate 5 is fixed to the dial 1 by fixing the support portion 51 to the bottom surface of the outer wall portion 14 of the dial 1 via the fixed plate 4. More specifically, four mounting holes corresponding to the caulking portions 15 are formed in the support portion 51 and the fixing plate 4 each. The caulking portion 15 is inserted into these mounting holes, and the caulking portion 15 is heat caulked with the fixed plate 4 in contact with the bottom surface of the outer wall portion 14 and the movable electrode plate 5 in contact with the fixed plate 4. To do. Thereby, the movable electrode plate 5 is fixed to the dial 1. When the dial 1 is rotated, the brush portion 52 rotates around the rotation center axis L while bringing the tip portion into contact with the rotation operation pattern 81 on the substrate 8. That is, the brush portion 52 corresponds to a “contact portion” according to the present invention.
[Center operation key and anti-rotation member]

中心操作キー6は、図1,2に示すごとく、内部が空洞のカップ形状の樹脂製部材である。中心操作キー6の内部には、平面視十字形状断面の受圧部61が下方に向けて立設してある。押圧部61は十字形状の断面形状に形成してあり、軽量化等のために中心操作キー6の厚さを薄くしても、径方向の剛性が維持される。   The center operation key 6 is a cup-shaped resin member having a hollow inside, as shown in FIGS. Inside the central operation key 6, a pressure receiving portion 61 having a cross-shaped cross section in plan view is erected downward. The pressing portion 61 is formed in a cross-shaped cross section, and the radial rigidity is maintained even if the thickness of the central operation key 6 is reduced for weight reduction or the like.

中心操作キー6の外周面の下部付近において、厚みを厚くすることにより段部63を形成してある。段部63よりも上側部分の外径は、ダイヤル1の内壁部13の内径よりも小さい。段部63よりも下側部分の外径は、ダイヤル1の内壁部13のうち段部13aよりも上側部分の内径よりも大きく、かつ、ダイヤル1の内壁部13のうち段部13aよりも下側部分の内径よりも小さい。これにより、スイッチを組み上げたときに、中心操作キー6はダイヤル1に対して上下方向に移動可能である。また、中心操作キー6がダイヤル1に対して上方向に移動した際、段部13aと段部63とが係止し、中心操作キー6が貫通部11から抜け出すことが防止される。   In the vicinity of the lower part of the outer peripheral surface of the central operation key 6, a stepped portion 63 is formed by increasing the thickness. The outer diameter of the upper part of the step part 63 is smaller than the inner diameter of the inner wall part 13 of the dial 1. The outer diameter of the lower part than the step part 63 is larger than the inner diameter of the upper part of the inner wall part 13 of the dial 1 than the step part 13a, and is lower than the step part 13a of the inner wall part 13 of the dial 1. It is smaller than the inner diameter of the side part. Thereby, when the switch is assembled, the center operation key 6 can move in the vertical direction with respect to the dial 1. Further, when the central operation key 6 moves upward with respect to the dial 1, the step portion 13 a and the step portion 63 are locked, and the central operation key 6 is prevented from coming out of the penetrating portion 11.

中心操作キー6の段部63よりも下側部分には、直径上に位置する二箇所に切欠部62を形成してある。切欠部62が後述する係止部73と係合することにより、中心操作キー6は基板8に対して回転しない。   Notch portions 62 are formed at two positions on the diameter below the step portion 63 of the central operation key 6. The center operation key 6 does not rotate with respect to the substrate 8 by engaging the notch 62 with a locking portion 73 described later.

回転防止部材7は、図1,2に示すごとく、基部71、受圧部72、係止部73、押圧部74、脚部75、及びかしめ部76を備えた樹脂製の部材である。基部71は、断面矩形状の環状に形成してある。基部71の外径は、中心操作キー6の外径と同じ程度の大きさである。脚部75は、基部71に対して180°毎に配設され、基部71を宙に浮かせた状態で下側から二箇所を支持している。受圧部72は、基部71の周内に納まる位置に配設され、その下部が二箇所の係止部73を介して基部71と連結されている。受圧部72の外径は、中心操作キー6の内径よりも小さい。係止部73は、基部71の上面のうち、脚部75に対して90°の間隔を空けた位置に形成してある。即ち、各係止部73は、周方向において脚部75と脚部75との中間に位置する。係止部73の幅は、中心操作キー6の切欠部62の幅よりも多少小さい。係止部73に中心操作キー6の切欠部62が嵌めこまれ、中心操作キー6が基板8に対して自由回転することが防止される。   As shown in FIGS. 1 and 2, the rotation preventing member 7 is a resin member including a base portion 71, a pressure receiving portion 72, a locking portion 73, a pressing portion 74, a leg portion 75, and a caulking portion 76. The base 71 is formed in an annular shape having a rectangular cross section. The outer diameter of the base 71 is approximately the same size as the outer diameter of the central operation key 6. The leg portions 75 are disposed every 180 ° with respect to the base portion 71, and support the two portions from the lower side in a state where the base portion 71 is suspended in the air. The pressure receiving portion 72 is disposed at a position that fits within the circumference of the base portion 71, and a lower portion thereof is connected to the base portion 71 via two locking portions 73. The outer diameter of the pressure receiving portion 72 is smaller than the inner diameter of the center operation key 6. The locking portion 73 is formed on the upper surface of the base portion 71 at a position spaced by 90 ° with respect to the leg portion 75. In other words, each locking portion 73 is located between the leg portion 75 and the leg portion 75 in the circumferential direction. The width of the locking portion 73 is slightly smaller than the width of the notch portion 62 of the center operation key 6. The notch 62 of the central operation key 6 is fitted into the locking portion 73, and the central operation key 6 is prevented from freely rotating with respect to the substrate 8.

かしめ部76は、ピン形状であり、脚部75の底面から下方に向けて三箇所立設形成してある。かしめ部76は、一方の脚部75に一箇所形成し、他方の脚部75に互いに離間させて二箇所形成してある。かしめ部76を基板8に形成された取付用の孔に夫々挿入し、脚部75の底面が基板8に接した状態で、かしめ部76を熱かしめして回転防止部材7を基板8に固定する。回転防止部材7は、かしめ部76によって三点支持されているので、基板8に対して安定する。ただし、仮に、かしめ部76が各脚部75に対して一箇所ずつしかなくても、つまり、回転防止部材7が二点で支持されるものであっても、脚部75が周方向に適度な長さを有し、かつ、脚部75と基板8とが密着していれば、回転防止部材7は基板8に対して安定する。   The caulking portion 76 has a pin shape, and is formed upright at three locations from the bottom surface of the leg portion 75 downward. The caulking portion 76 is formed at one place on one leg 75 and is formed at two places on the other leg 75 so as to be separated from each other. The caulking portions 76 are respectively inserted into mounting holes formed in the substrate 8, and the caulking portions 76 are heat caulked in a state where the bottom surfaces of the leg portions 75 are in contact with the substrate 8 to fix the rotation preventing member 7 to the substrate 8. To do. Since the rotation preventing member 7 is supported at three points by the caulking portion 76, it is stable with respect to the substrate 8. However, even if there is only one caulking portion 76 with respect to each leg portion 75, that is, even if the rotation preventing member 7 is supported at two points, the leg portion 75 is moderate in the circumferential direction. If the leg portion 75 and the substrate 8 are in close contact with each other, the rotation preventing member 7 is stable with respect to the substrate 8.

受圧部72に対して中心操作キー6が覆い被せられ、押圧部61が受圧部72の天端に接触する。中心操作キー6が押し操作されると、その操作力が押圧部61を介して受圧部72に伝達される。上述したように、基部71の断面形状が矩形状であり、かつ、脚部75同士が180°の中心角をもって離間しているため、受圧部72が上方から押圧されると、基部71は脚部75を支点として下方にたわんで変形する。回転防止部材7は樹脂製であるため、この変形は弾性変形であり、押圧力を除去すると基部71は元の状態に戻る。   The central operation key 6 is covered with the pressure receiving portion 72, and the pressing portion 61 contacts the top end of the pressure receiving portion 72. When the center operation key 6 is pressed, the operating force is transmitted to the pressure receiving portion 72 via the pressing portion 61. As described above, since the cross-sectional shape of the base portion 71 is rectangular and the leg portions 75 are separated from each other with a central angle of 180 °, when the pressure receiving portion 72 is pressed from above, the base portion 71 The portion 75 is deformed by bending downward with the fulcrum as a fulcrum. Since the rotation preventing member 7 is made of resin, this deformation is elastic deformation, and the base 71 returns to the original state when the pressing force is removed.

〔基板について〕
基板8には、図1,2に示すごとく、上述したように、導電性の回転操作用パターン81と、導電性の四方向操作用パターン82と、導電性の中心操作用パターン83と、がプリントされている。スイッチの組み上がり時には、基板8は可動電極板5と対向する。各パターンは、上述した不図示の検出手段に接続されている。
[About the board]
As shown in FIGS. 1 and 2, the substrate 8 includes the conductive rotation operation pattern 81, the conductive four-direction operation pattern 82, and the conductive center operation pattern 83 as described above. It is printed. When the switch is assembled, the substrate 8 faces the movable electrode plate 5. Each pattern is connected to the detection means (not shown) described above.

四方向操作用パターン82及び中心操作用パターン83は、図1に示すごとく、環状のパターンと、環中央部分のパターンとを備える公知の電極パターンである。スナップ板10を四方向操作用パターン82及び中心操作用パターン83に載置し、シート状の貼付テープTで固定してある。スナップ板10は、図1,2に示すごとく、中央部が膨出した金属製部材である。スナップ板10は、四方向操作用パターン82及び中心操作用パターン83と平面視で略同サイズであり、外周部の一部または全部が、各パターン82,83のうちの環状のパターンに常時接触している。スナップ板10は、中央部付近に押圧力が作用すると弾性変形し、その頂点部分が各パターン82,83のうちの中央のパターンに接触する。これにより、四方向操作用パターン82,中心操作用パターン83がスナップ板10を介して電気的に導通状態となる。押圧力が除去されると、スナップ板10は元の形状に復帰し、導通状態は解除される。なお、スナップ板10は、押圧によって頂点部分が転勤点を越えない程度の膨出高さとしてある。   As shown in FIG. 1, the four-way operation pattern 82 and the center operation pattern 83 are well-known electrode patterns including an annular pattern and a ring central portion pattern. The snap plate 10 is placed on the four-direction operation pattern 82 and the center operation pattern 83 and fixed with a sheet-like adhesive tape T. As shown in FIGS. 1 and 2, the snap plate 10 is a metal member having a bulged central portion. The snap plate 10 is substantially the same size in plan view as the four-direction operation pattern 82 and the center operation pattern 83, and part or all of the outer peripheral portion is always in contact with the annular pattern of the patterns 82 and 83. is doing. The snap plate 10 is elastically deformed when a pressing force is applied in the vicinity of the central portion, and the apex portion of the snap plate 10 contacts the central pattern of the patterns 82 and 83. As a result, the four-way operation pattern 82 and the center operation pattern 83 are electrically connected via the snap plate 10. When the pressing force is removed, the snap plate 10 returns to its original shape and the conductive state is released. Note that the snap plate 10 has a bulging height that does not exceed the transfer point due to the pressing.

回転操作用パターン81は、図4に示すごとく、「被接触部」としての一以上のA相81a、「被接触部」としての一以上のB相81b、「被接触部」としての一以上のC相81c、及び、「被接触部」としての一以上のE相81dを備えている。A相81a、B相81b、C相81c、及びE相81dは、ブラシ部52の先端部の回転軌跡上に、互いに離間して配置されている。A相81a、B相81b、C相81cの下流側は、上述した不図示の検出手段に接続してある。E相81dは下流で接地してある。   As shown in FIG. 4, the rotation operation pattern 81 includes one or more A phases 81 a as “contacted portions”, one or more B phases 81 b as “contacted portions”, and one or more as “contacted portions”. C phase 81c and one or more E phases 81d as “contacted parts”. The A phase 81 a, the B phase 81 b, the C phase 81 c, and the E phase 81 d are arranged apart from each other on the rotation locus of the tip portion of the brush portion 52. The downstream side of the A phase 81a, the B phase 81b, and the C phase 81c is connected to the detection means (not shown). The E phase 81d is grounded downstream.

A相81aは、B相81b及びC相81cを介することなく三つ連続して備えられ、互いに接続されている。B相81bは、A相81a及びC相81cを介することなく三つ連続して備えられ、互いに接続されている。C相81cは、A相81a及びB相81bを介することなく三つ連続して備えられ、互いに接続されている。E相81dは、A相81a,B相81b,C相81cの各相の間に備えられ、互いに接続されている。A相81aの集合体が、本発明に係る「第一電極パターン」に相当する。B相81bの集合体が、本発明に係る「第二電極パターン」に相当する。C相81cの集合体が、本発明に係る「共通電極パターン」に相当する。E相81dの集合体が、本発明に係る「接地電極パターン」に相当する。各相の間には僅かな隙間を備えてあり、各相同士は互いに導通しない。   Three A phases 81a are provided in succession without interposing B phase 81b and C phase 81c, and are connected to each other. Three B phases 81b are provided in succession without interposing A phase 81a and C phase 81c, and are connected to each other. Three C phases 81c are provided continuously without interposing the A phase 81a and the B phase 81b, and are connected to each other. The E phase 81d is provided between the A phase 81a, the B phase 81b, and the C phase 81c, and is connected to each other. The aggregate of the A phase 81a corresponds to the “first electrode pattern” according to the present invention. The aggregate of the B phase 81b corresponds to the “second electrode pattern” according to the present invention. The aggregate of the C phase 81c corresponds to the “common electrode pattern” according to the present invention. The aggregate of the E phase 81d corresponds to the “ground electrode pattern” according to the present invention. There are slight gaps between the phases, and the phases do not conduct each other.

なお、基板8の底に補強板9を沿わせることにより、基板の剛性を高めている。   Note that the rigidity of the substrate is increased by placing the reinforcing plate 9 along the bottom of the substrate 8.

〔スイッチの組付について〕
図1,図2に基づいて、スイッチの組付について説明する。まず、ダイヤル1に「抵抗部」としての感触用バネ3を配設する。感触用バネ3は、板バネとして機能する両端のバネ部31と、両バネ部31の中央付近に設けられた取付部32とを備えている。バネ部31の両側の先端部分は、感触部22の凹凸形状のうちの凹形状に対応する形状に形成してある。バネ部31の先端部分同士の離間距離は、キートップ2の感触部22の凹部における外径よりも小さく設定してある。取付部32を介して、感触用バネ3をダイヤル1の凹入部12の上面に取り付ける。
[Switch assembly]
The assembly of the switch will be described with reference to FIGS. First, the touch spring 3 as a “resistor” is disposed on the dial 1. The touch spring 3 includes spring portions 31 at both ends that function as leaf springs, and attachment portions 32 provided near the center of both spring portions 31. The tip portions on both sides of the spring portion 31 are formed in a shape corresponding to the concave shape among the concave and convex shapes of the feeler portion 22. The separation distance between the tip portions of the spring portion 31 is set to be smaller than the outer diameter of the concave portion of the touch portion 22 of the key top 2. The feel spring 3 is attached to the upper surface of the recessed portion 12 of the dial 1 via the attachment portion 32.

内壁部13を感触部22の内部に挿入するよう、ダイヤル1をキートップ2に組み込む。このとき、感触用バネ3が感触部22の天端に干渉しないよう、バネ部31を両外側へ押し広げて挿入作業を行う。ダイヤル1は、外壁部14の底面が受圧部21aに接触するまでキートップ2に挿入する。かしめ部15に、固定板4と可動電極板5とを順に嵌め込んで、かしめ部15を熱かしめする。この結果、ダイヤル1が上方に移動しても、固定板4が感触部22の底面22cに係止し、ダイヤル1はキートップ2から抜け出すことがない。ただし、内壁部13は、ダイヤル1が下方に押し操作され得る程度に、その高さを設定してある。   The dial 1 is incorporated into the key top 2 so that the inner wall 13 is inserted into the feeler 22. At this time, insertion is performed by spreading the spring portion 31 outward so that the touch spring 3 does not interfere with the top end of the touch portion 22. The dial 1 is inserted into the key top 2 until the bottom surface of the outer wall portion 14 contacts the pressure receiving portion 21a. The fixed plate 4 and the movable electrode plate 5 are fitted into the caulking portion 15 in order, and the caulking portion 15 is heat caulked. As a result, even if the dial 1 moves upward, the fixing plate 4 is locked to the bottom surface 22c of the touch portion 22, and the dial 1 does not come out of the key top 2. However, the height of the inner wall portion 13 is set to such an extent that the dial 1 can be pushed downward.

一方、基板8にはスナップ板10を貼付テープTで固定してある。そして、基板8に回転防止部材7を固定し、回転防止部材7に中心操作キー6を覆い被せる。このような状態の基板8に、ダイヤル1を組み込んだ状態のキートップ2を固定する。中心操作キー6は、ダイヤル1の内壁部13の内部に挿入されることとなり、上述した段部13aと段部63とにより、中心操作キー6がダイヤル1から抜け出すことはない。スイッチの組み上がりの斜視図を図3に示す。   On the other hand, a snap plate 10 is fixed to the substrate 8 with an adhesive tape T. Then, the rotation preventing member 7 is fixed to the substrate 8, and the center operation key 6 is covered with the rotation preventing member 7. The key top 2 in which the dial 1 is incorporated is fixed to the substrate 8 in such a state. The central operation key 6 is inserted into the inner wall portion 13 of the dial 1, and the central operation key 6 does not come out of the dial 1 by the step portion 13 a and the step portion 63 described above. FIG. 3 shows a perspective view of the assembled switch.

可動電極板5の先端部は、図2に示すごとく、回転操作用パターン81に接触する。上述したように、ブラシ部52は支持部51から下方に折り曲げられているので、ダイヤル1と基板8とに挟持されることにより、板バネとしても機能する。即ち、ブラシ部52がダイヤル1を上方に常時付勢し、通常の状態でダイヤル1がキートップ2に対して沈み込むことはない。   The tip of the movable electrode plate 5 is in contact with the rotation operation pattern 81 as shown in FIG. As described above, since the brush portion 52 is bent downward from the support portion 51, the brush portion 52 functions as a leaf spring by being sandwiched between the dial 1 and the substrate 8. That is, the brush portion 52 always urges the dial 1 upward, and the dial 1 does not sink into the key top 2 in a normal state.

以上の構成により、ダイヤル1及び可動電極板5は、基板8に対して、図3に「+」で示す半時計回りにも、「−」で示す時計回りにも回転中心軸Lの周りに回転可能となる。感触部22の凹凸形状は、30°ごとに繰り返される形状であって、かつ、感触用バネ3は凹形状に嵌り込んだ状態が最も安定するため、ダイヤル1は30°毎に位置保持される。即ち、30°毎にダイヤル1には回転抵抗が付与される。この結果、使用者は30°毎にクリック感を得ることができ、回転操作量を体感できる。回転操作による回転操作用パターン81の導通及び非導通については後述する。   With the above configuration, the dial 1 and the movable electrode plate 5 are rotated around the rotation center axis L with respect to the substrate 8 in a counterclockwise direction indicated by “+” in FIG. It can be rotated. The concavo-convex shape of the touch portion 22 is a shape that repeats every 30 °, and the touch spring 3 is most stable when fitted into the concave shape, so that the dial 1 is held at every 30 °. . That is, a rotational resistance is applied to the dial 1 every 30 °. As a result, the user can obtain a click feeling every 30 °, and can experience the amount of rotation operation. The conduction and non-conduction of the rotation operation pattern 81 by the rotation operation will be described later.

図2に示すごとく、キートップ2の押圧部21bは、スナッププレートを介した状態で四方向操作用パターン82に対向する。感触部22の内周面22bの内径は、上方に向って若干拡径してある。一方、感触部22の内周面22bの内径は、下部ではダイヤル1の内壁部13の外径よりも僅かに大きい程度に設定してある。これらにより、ダイヤル1は、キートップ2に対してガタつくことはないものの、ダイヤル1の上面のうち受圧部21aに対応する位置を押し操作することにより、四方向への傾動操作が可能である。なお、ダイヤル1を押す位置が受圧部21aから多少外れていても、受圧部21aが基部21に対して90°毎に均等形成され、ダイヤル1を点支持しているため、操作力は、傾動させたい方向に対応する受圧部21aに最も作用する。   As shown in FIG. 2, the pressing portion 21b of the key top 2 faces the four-way operation pattern 82 with the snap plate interposed therebetween. The inner diameter of the inner peripheral surface 22b of the touch part 22 is slightly enlarged toward the upper side. On the other hand, the inner diameter of the inner peripheral surface 22b of the touch part 22 is set to be slightly larger than the outer diameter of the inner wall part 13 of the dial 1 at the lower part. As a result, the dial 1 does not rattle with respect to the key top 2, but can be tilted in four directions by pressing the position corresponding to the pressure receiving portion 21a on the upper surface of the dial 1. . Even if the position where the dial 1 is pressed is slightly deviated from the pressure receiving portion 21a, the pressure receiving portion 21a is uniformly formed with respect to the base portion 21 every 90 °, and the dial 1 is point-supported. It acts most on the pressure receiving part 21a corresponding to the direction to be made.

ダイヤル1を四方向に傾動操作すると、その操作力は基部21の受圧部21aに伝達される。そして、基部21が下方に沈み込み、押圧部21bがスナップ板10を押圧する。スナップ板10が四方向操作用パターン82に接触すると、四方向操作用パターン82の何れか一つが導通状態となり、傾動操作された方向が検出される。傾動操作力を除去すると、基部21の弾性力により、ダイヤル1及びスナップ板10は元の状態に復帰する。   When the dial 1 is tilted in four directions, the operating force is transmitted to the pressure receiving portion 21a of the base portion 21. Then, the base portion 21 sinks downward, and the pressing portion 21b presses the snap plate 10. When the snap plate 10 comes into contact with the four-way operation pattern 82, any one of the four-way operation patterns 82 becomes conductive, and the direction in which the tilt operation is performed is detected. When the tilting operation force is removed, the dial 1 and the snap plate 10 are restored to the original state by the elastic force of the base 21.

図2に示すごとく、回転防止部材7の押圧部74は、スナッププレートを介した状態で中心操作用パターン83に対向している。中心操作キー6は、外周部をダイヤル1の内壁部13に包持されるため、径方向へはガタつかない。中心操作キー6を回転中心軸Lに沿って押し操作すると、その操作力は押圧部61を介して回転防止部材7に伝達される。そして、回転防止部材7が下方へ沈み込み、押圧部74がスナップ板10を押圧する。スナップ板10が中心操作用パターン83に接触すると、中心操作用パターン83が導通状態となり、中心操作が検出される。   As shown in FIG. 2, the pressing portion 74 of the rotation preventing member 7 faces the center operation pattern 83 with the snap plate interposed therebetween. The center operation key 6 is not rattled in the radial direction because the outer peripheral portion is held by the inner wall portion 13 of the dial 1. When the center operation key 6 is pushed along the rotation center axis L, the operation force is transmitted to the rotation preventing member 7 through the pressing portion 61. Then, the rotation preventing member 7 sinks downward, and the pressing portion 74 presses the snap plate 10. When the snap plate 10 comes into contact with the center operation pattern 83, the center operation pattern 83 becomes conductive, and the center operation is detected.

中心操作は、例えば、四方向操作や回転操作の後に行って、夫々の操作の確定を行うものである。即ち、中心操作キー6は「確定キー」のごとき役割をなす。   The center operation is performed after, for example, a four-way operation or a rotation operation, and each operation is confirmed. That is, the central operation key 6 plays a role like a “confirmation key”.

〔スイッチの回転操作について〕
可動電極板5と回転操作用パターン81との位置関係に基づき、ダイヤル1を回転操作したときの回転操作用パターン81の導通、非導通について説明する。図5において、可動電極板5と回転操作用パターン81とは模式的に表現してある。ブラシ部52は十字形状に表現し、A相81a、B相81b、C相81cの少なくとも二つが導通したときは、導通した相に接するブラシ部52を黒く塗りつぶしてある。
[Switch rotation operation]
Based on the positional relationship between the movable electrode plate 5 and the rotation operation pattern 81, conduction and non-conduction of the rotation operation pattern 81 when the dial 1 is rotated will be described. In FIG. 5, the movable electrode plate 5 and the rotation operation pattern 81 are schematically represented. The brush portion 52 is expressed in a cross shape, and when at least two of the A phase 81a, the B phase 81b, and the C phase 81c are conducted, the brush portion 52 that is in contact with the conducted phase is painted black.

図5(d)に示すごとく、A相81aとC相81cとが導通したときは、図6におけるA相81aが「ON」となったときのパルス波が発生する。また、図5(b)に示すごとく、B相81bとC相81cとが導通したときは、図6におけるB相81bが「ON」となったときのパルス波が発生する。さらに、図5(c)に示すごとく、A相81aとB相81bとC相81cとが導通したときは、図6におけるA相81aとB相81bとの両方が「ON」となったときのパルス波が発生する。スイッチは、このような三種の導通状態を検出可能であって、これらの導通状態が、本発明に係る「第一状態」に相当する。   As shown in FIG. 5D, when the A-phase 81a and the C-phase 81c are conducted, a pulse wave is generated when the A-phase 81a in FIG. 6 is “ON”. Further, as shown in FIG. 5B, when the B phase 81b and the C phase 81c are conducted, a pulse wave is generated when the B phase 81b in FIG. 6 is turned “ON”. Further, as shown in FIG. 5C, when the A phase 81a, the B phase 81b, and the C phase 81c are conducted, both the A phase 81a and the B phase 81b in FIG. The pulse wave is generated. The switch can detect such three kinds of conduction states, and these conduction states correspond to the “first state” according to the present invention.

図5(a)に示すごとく、ブラシ部52がA相81a、B相81b、C相81cの何れもと接触しないときは、図6に示す全絶縁状態が発生する。このとき、全てのブラシ部52は、E相81dと接触している。よって、回転途中において、可動電極板5と回転操作用パターン81との摺設により発生して可動電極板5に帯電した静電気や、外部からスイッチ内に侵入して可動電極板5に帯電した静電気は、E相81dを介して接地されて放電される。この全絶縁状態が、本発明に係る「第二状態」に相当する。   As shown in FIG. 5A, when the brush portion 52 does not come into contact with any of the A phase 81a, the B phase 81b, and the C phase 81c, the total insulation state shown in FIG. 6 occurs. At this time, all the brush portions 52 are in contact with the E phase 81d. Therefore, during the rotation, static electricity generated by sliding between the movable electrode plate 5 and the rotation operation pattern 81 and charged to the movable electrode plate 5, or static electricity that entered the switch from the outside and charged to the movable electrode plate 5 is charged. Are grounded via the E phase 81d and discharged. This total insulation state corresponds to the “second state” according to the present invention.

また、可動電極板5が360°回転する間において、全絶縁状態が12回発生するよう、可動電極板5及び回転操作用パターン81は構成してある。即ち、30°毎に全絶縁状態が発生する。さらに、感触部22と感触用バネ3による回転抵抗が発生するタイミングが、全絶縁状態が発生するタイミングと合致するよう構成してある。よって、回転操作を確実に全絶縁状態で停止させることができ、可動電極板5に帯電した静電気は確実に接地される。   Further, the movable electrode plate 5 and the rotation operation pattern 81 are configured so that the total insulation state occurs 12 times while the movable electrode plate 5 rotates 360 °. That is, the entire insulation state occurs every 30 °. Furthermore, the timing at which the rotational resistance is generated by the touching part 22 and the touching spring 3 is configured to coincide with the timing at which the fully insulated state occurs. Therefore, the rotation operation can be reliably stopped in a completely insulated state, and the static electricity charged on the movable electrode plate 5 is reliably grounded.

なお、図示はしないが、E相81dの下流に抵抗を設けてある。これにより、ブラシ部52が、A相81a、B相81b、C相81cのうち少なくとも二つと接触しつつE相81dにも接触した状態となっても、電流はE相81dを介して接地されず、導通状態に応じた適正なパルス波が発生する。   Although not shown, a resistor is provided downstream of the E phase 81d. As a result, even when the brush portion 52 is in contact with at least two of the A phase 81a, B phase 81b, and C phase 81c and also in contact with the E phase 81d, the current is grounded via the E phase 81d. Instead, an appropriate pulse wave corresponding to the conduction state is generated.

以下に、回転情報を検出するメカニズムについて簡単に説明する。可動電極板5が、図5(a)から「+」方向に(e)まで回転すると、図6の0°から30°に相当にする箇所に示されるごとく、「全絶縁状態」→「A相81a:OFF/B相81b:ON」→「A相81a/B相81b:ON」→「A相81a:ON/B相81b:OFF」→「全絶縁状態」の順序のパルス波が発生する。逆に、に示すごとく、可動電極板5が、図5(e)から「−」方向に(a)まで回転すると、図6の30°から0°に相当する箇所に示されるごとく、「全絶縁状態」→「A相81a:ON/B相81b:OFF」→「A相81a/B相81b:ON」→「A相81a:OFF/B相81b:ON」→「全絶縁状態」の順序のパルス波が発生する。このパルス波を判別することによって、可動電極板5が「+」方向もしくは「−」方向の何れに回転したか検出できる。また、二つのパターンのパルス波の発生回数を判定することにより、可動電極板5の回転量を検出することができる。   A mechanism for detecting rotation information will be briefly described below. When the movable electrode plate 5 is rotated in the “+” direction from FIG. 5A to (e), as shown in the position corresponding to 0 ° to 30 ° in FIG. Phase 81a: OFF / B phase 81b: ON "→" A phase 81a / B phase 81b: ON "→" A phase 81a: ON / B phase 81b: OFF "→ Pulse waves in the order of" all insulation state "are generated To do. On the contrary, as shown in FIG. 6, when the movable electrode plate 5 is rotated from the direction of FIG. 5 (e) to the direction of “−” to (a), as shown in the portion corresponding to 30 ° to 0 ° in FIG. “Insulation state” → “A phase 81a: ON / B phase 81b: OFF” → “A phase 81a / B phase 81b: ON” → “A phase 81a: OFF / B phase 81b: ON” → “All insulation state” An order pulse wave is generated. By discriminating this pulse wave, it is possible to detect whether the movable electrode plate 5 is rotated in the “+” direction or the “−” direction. In addition, the amount of rotation of the movable electrode plate 5 can be detected by determining the number of occurrences of pulse waves of two patterns.

図5は、可動電極板5を「+」方向に90°回転させたときの状態を(a)から(l)に示すものである。(a)から(e)において、「A相81a:OFF/B相81b:ON」→「A相81a/B相81b:ON」→「A相81a:ON/B相81b:OFF」の順序のパルス波が発生し、(e)の状態で可動電極板5に帯電した静電気は接地される。引き続き、(e)から(i)においても、「A相81a:OFF/B相81b:ON」→「A相81a/B相81b:ON」→「A相81a:ON/B相81b:OFF」の順序のパルス波が発生し、(i)の状態で可動電極板5に帯電した静電気は再び接地される。さらに、(i)から(l)においても、「A相81a:OFF/B相81b:ON」→「A相81a/B相81b:ON」→「A相81a:ON/B相81b:OFF」の順序のパルス波が発生する。その後、再度(a)の状態となり、可動電極板5に帯電した静電気は再び接地される。   FIG. 5 shows a state when the movable electrode plate 5 is rotated by 90 ° in the “+” direction from (a) to (l). In (a) to (e), the order of “A phase 81a: OFF / B phase 81b: ON” → “A phase 81a / B phase 81b: ON” → “A phase 81a: ON / B phase 81b: OFF” And the static electricity charged on the movable electrode plate 5 in the state (e) is grounded. Subsequently, also in (e) to (i), “A phase 81a: OFF / B phase 81b: ON” → “A phase 81a / B phase 81b: ON” → “A phase 81a: ON / B phase 81b: OFF” In this state, the static electricity charged in the movable electrode plate 5 is grounded again. Further, also in (i) to (l), “A phase 81a: OFF / B phase 81b: ON” → “A phase 81a / B phase 81b: ON” → “A phase 81a: ON / B phase 81b: OFF” In the order of "." Thereafter, the state (a) is established again, and the static electricity charged on the movable electrode plate 5 is grounded again.

即ち、可動電極板5が「+」方向に回転すると、図6に示すごとく、30°毎に「全絶縁状態」→「A相81a:OFF/B相81b:ON」→「A相81a/B相81b:ON」→「A相81a:ON/B相81b:OFF」→「全絶縁状態」が繰り返され、かつ、図5に示すごとく、可動電極板5と回転用電極パターンとの位置関係は90°の周期で繰り返される。可動電極板5が「−」方向に回転した場合も同様に、図6に示すごとく、30°毎に「全絶縁状態」→「A相81a:ON/B相81b:OFF」→「A相81a/B相81b:ON」→「A相81a:OFF/B相81b:ON」→「全絶縁状態」が繰り返され、かつ、図5に示すごとく、可動電極板5と回転用電極パターンとの位置関係は90°の周期で繰り返される。   That is, when the movable electrode plate 5 rotates in the “+” direction, as shown in FIG. 6, “all insulation state” → “A phase 81a: OFF / B phase 81b: ON” → “A phase 81a / B phase 81b: ON ”→“ A phase 81a: ON / B phase 81b: OFF ”→“ all insulation state ”is repeated, and as shown in FIG. 5, the positions of the movable electrode plate 5 and the rotating electrode pattern The relationship repeats with a 90 ° period. Similarly, when the movable electrode plate 5 rotates in the “−” direction, as shown in FIG. 6, “all insulation state” → “A phase 81a: ON / B phase 81b: OFF” → “A phase” every 30 °. 81a / B phase 81b: ON ”→“ A phase 81a: OFF / B phase 81b: ON ”→“ all insulation state ”is repeated, and as shown in FIG. 5, the movable electrode plate 5 and the rotating electrode pattern The positional relationship is repeated at a period of 90 °.

以上、本発明の構成であると、E相81dが、A相81a、B相81b、C相81cと同じ円状に配置されているため、回転操作用パターン81の径が大きくならず、スイッチの回転径方向への小型化を図ることができる。また、30°回転する毎に、可動電極板5に帯電した静電気が接地されるため、回転操作速度が速く、E相81dと可動電極板5の接触時間が短い場合であっても、接地回数が多く小まめに静電気がクリアされる。この結果、スイッチの回転操作検出が静電気によって阻害されることが防止される。   As described above, in the configuration of the present invention, since the E phase 81d is arranged in the same circular shape as the A phase 81a, the B phase 81b, and the C phase 81c, the diameter of the rotation operation pattern 81 is not increased, and the switch It is possible to reduce the size in the direction of the rotation diameter. In addition, since the static electricity charged to the movable electrode plate 5 is grounded every 30 ° rotation, the number of times of grounding is high even when the rotational operation speed is high and the contact time between the E phase 81d and the movable electrode plate 5 is short. There are many, and static electricity is cleared by small amount. As a result, it is possible to prevent the detection of the rotation operation of the switch from being disturbed by static electricity.

なお、可動電極板5が360°回転する間に発生する全絶縁状態の回数は、本実施形態の数に限られるものではない。全絶縁状態の発生回数は、ブラシの数や、A相、B相、C相、E相の数・配置によって簡便に変更が可能である。
相、B相、C相、E相の数・配置によって簡便に変更が可能である。
It should be noted that the number of all insulation states that occur while the movable electrode plate 5 rotates 360 ° is not limited to the number in the present embodiment. The number of occurrences of the total insulation state can be easily changed by the number of brushes and the number / arrangement of the A phase, B phase, C phase, and E phase.
The number can be easily changed depending on the number and arrangement of phases, B phases, C phases, and E phases.

また、上述の実施形態においては、四方向へのダイヤル1の傾動操作が可能なようにキートップ2を構成したが、これに限定されるものではない。例えば、二方向、六方向、八方向へのダイヤル1の傾動操作が可能なようキートップ2を構成しても良い。この場合は、受圧部21a及び脚部23の数や割付、基部21の厚み等を適宜変更すれば良い。   Moreover, in the above-mentioned embodiment, although the key top 2 was comprised so that the tilting operation of the dial 1 to four directions was possible, it is not limited to this. For example, the key top 2 may be configured so that the dial 1 can be tilted in two directions, six directions, and eight directions. In this case, what is necessary is just to change suitably the number and allocation of the pressure receiving part 21a and the leg part 23, the thickness of the base 21, etc. FIG.
