Description

本発明は、押圧操作用のプッシュスイッチを備えた回転型電気部品に係り、特に、中央部に他の部品の収納スペースが確保されているプッシュスイッチ付き回転型電気部品に関する。 The present invention relates to a rotary electrical component including a push switch for pressing operation, and more particularly to a rotary electrical component with a push switch in which a storage space for other components is secured in the center.

プッシュスイッチ付き回転型電気部品として、回転可能かつ軸線方向へ往復動可能な操作軸を中央部に組み込み、この操作軸の後方にプッシュスイッチを設置すると共に、操作軸にスプライン結合された回転体等を含む回転検出手段（エンコーダや可変抵抗器）を操作軸の周囲に配設するという構成のものが広く知られている。このものは、操作軸を軸線方向へ押圧操作すると、プッシュスイッチが押圧駆動されてスイッチオン信号が出力され、操作軸を回転操作すると、回転体が供回りして回転検出手段にて操作軸の回転情報が検出されるようになっている。 As a rotating electrical part with push switch, an operation shaft that can rotate and reciprocate in the axial direction is incorporated in the center, a push switch is installed behind this operation shaft, and a rotating body that is splined to the operation shaft A rotation detecting means including an encoder (variable resistor or encoder) is widely known around the operating shaft. When the operating shaft is pressed in the axial direction, the push switch is pressed and a switch-on signal is output, and when the operating shaft is rotated, the rotating body is rotated and the rotation detecting means rotates the operating shaft. Rotation information is detected.

しかしながら、上述した回転型電気部品の中央部には操作軸やプッシュスイッチが配設されているため、該中央部に他の部品を組み込むことができず、例えば照光用のＬＥＤ等の他の部品を追加する場合には、その部品を回転型電気部品の外側に配設しなければならない。それゆえ、かかる回転型電気部品を他の部品と組み合わせて多機能化を図ると、実装領域が不所望に拡大してしまったり、操作軸に取着されるつまみ部材の中央部が照光させにくい等の不具合を生じていた。 However, since the operation shaft and the push switch are disposed in the central portion of the rotary electrical component described above, other components cannot be incorporated in the central portion, and other components such as an illumination LED, for example. When adding a component, the component must be disposed outside the rotating electrical component. Therefore, when such a rotary electric component is combined with other components to achieve multiple functions, the mounting area is undesirably enlarged or the central portion of the knob member attached to the operation shaft is difficult to illuminate. Etc. were caused.

そこで従来、中空状の操作軸を回転可能かつ軸線方向へ往復動可能に組み込むことによって、中央部に他の部品の収納スペースを確保したプッシュスイッチ付き回転型電気部品が提案されている（例えば、特許文献１参照）。かかる従来提案において、回転型電気部品のハウジングには、操作軸を回転可能かつ軸線方向へ往復動可能に支持する中空状の軸受部と、該軸受部の周囲に回転検出手段（エンコーダ）と複数のプッシュスイッチとを配設するための環状の収納部とが設けられており、軸受部に包囲された円柱状の内方空間が他の部品の収納スペースとして利用できるようになっている。回転検出手段には、操作軸にスプライン結合されて摺動子が取着された回転体と、該摺動子が摺動可能な導電パターンとが設けられており、操作軸が回転操作されると、回転体が供回りして摺動子が導電パターンに接離するため、操作軸の回転情報を検出することができる。また、略等間隔に配設された複数（例えば３個）のプッシュスイッチ上にリング状の押圧部材が安定した姿勢で搭載されているため、操作軸が押圧操作されると、少なくともいずれか１個のプッシュスイッチが押圧部材を介して押圧駆動されるようになっている。つまり、操作軸と軸受部との間には若干のクリアランスが必要なため、押圧操作時に操作軸が斜めに傾いた状態で押し込まれることがあるが、その場合にも操作軸と同じ向きに傾く押圧部材によって、傾いた側に存するプッシュスイッチを押圧駆動することができるため、操作軸がどの向きに傾いても必ずいずれかのプッシュスイッチは押圧駆動されてスイッチオン信号を出力させることができる。こうすることによって押圧操作時に動作不良が起こりにくくなるため、信頼性を大幅に高めることができる。 Therefore, conventionally, a rotary electrical component with a push switch that secures a storage space for other components in the central portion by incorporating a hollow operation shaft so that it can rotate and reciprocate in the axial direction has been proposed (for example, Patent Document 1). In such a conventional proposal, the rotary electric component housing includes a hollow bearing portion that supports the operating shaft so as to be rotatable and reciprocally movable in the axial direction, and a rotation detecting means (encoder) and a plurality of rotation detectors around the bearing portion. An annular storage portion for arranging the push switch is provided, and a cylindrical inner space surrounded by the bearing portion can be used as a storage space for other components. The rotation detecting means is provided with a rotating body splined to the operation shaft and attached with a slider, and a conductive pattern on which the slider can slide, and the operation shaft is rotated. Then, since the rotating body is rotated and the slider comes in contact with and separates from the conductive pattern, the rotation information of the operation shaft can be detected. In addition, since the ring-shaped pressing member is mounted in a stable posture on a plurality of (for example, three) push switches arranged at substantially equal intervals, at least one of them is pressed when the operation shaft is pressed. Each push switch is driven to be pressed through a pressing member. In other words, since a slight clearance is required between the operation shaft and the bearing portion, the operation shaft may be pushed in an inclined state during the pressing operation, but in this case, the operation shaft is also inclined in the same direction. Since the push switch on the inclined side can be pressed and driven by the pressing member, any push switch is always driven to be pressed and a switch-on signal can be output regardless of the direction of the operation shaft. By doing so, it becomes difficult for malfunctions to occur during the pressing operation, so the reliability can be greatly increased.

ところで、特許文献１に開示されている従来の回転型電気部品では、押圧操作時に操作軸が傾いた状態で押し込まれても確実にプッシュスイッチが押圧駆動できるようにするため、複数のプッシュスイッチを略等間隔に配設して信頼性を高めているが、これら複数のプッシュスイッチが時間差をもって連続的に押圧駆動されたときに、各プッシュスイッチの生起するクリック感が操作者の手指に連続的に伝わってしまうという問題があった。すなわち、各プッシュスイッチには反転時にクリック感を生起するドーム状のメタルコンタクトが内蔵されているため、複数のプッシュスイッチが同時に押圧駆動されない限り各メタルコンタクトの反転するタイミングにズレが生じてしまい、それゆえ押圧操作時にクリック感の重複が起こって操作感触が損なわれやすかった。 By the way, in the conventional rotary electric component disclosed in Patent Document 1, a plurality of push switches are provided in order to ensure that the push switch can be driven by pressing even when the operation shaft is tilted during the pressing operation. Although the reliability is improved by arranging them at substantially equal intervals, when these multiple push switches are continuously pressed and driven with a time difference, the click feeling generated by each push switch is continuously applied to the fingers of the operator. There was a problem of being transmitted to. That is, each push switch has a built-in dome-shaped metal contact that causes a click feeling at the time of reversal.Therefore, unless a plurality of push switches are driven to be pressed at the same time, a deviation occurs at the timing of reversing each metal contact. Therefore, the click feeling is duplicated during the pressing operation, and the operation feeling is likely to be impaired.

本発明は、このような従来技術の実情に鑑みてなされたものであり、その目的は、押圧操作時に動作不良を起こしにくくて信頼性が高く、かつクリック感の重複も起こらず操作感触が良好な回転型電気部品を提供することにある。 The present invention has been made in view of the situation of the prior art as described above, and the purpose thereof is high in reliability because it is less likely to cause malfunction during a pressing operation, and there is no duplication of the click feeling. Is to provide a rotating electrical component.

上記の目的を達成するために、本発明の回転型電気部品では、中空状の軸受部を有すると共に該軸受部の周囲に環状の収納部を有するハウジングと、前記軸受部に外挿されて回転可能かつ軸線方向へ往復動可能に支持された中空状の操作軸と、前記収納部に配設されて前記操作軸の回転情報を検出する回転検出手段と、傾動支点部および作用点部を有して前記収納部に配設され、前記操作軸に対する軸線方向への押圧操作力によって傾動する駆動体と、前記収納部に配設されて前記駆動体の前記作用点部に押圧駆動されるプッシュスイッチとを備え、前記駆動体に前記傾動支点部と前記作用点部とが前記操作軸の回転中心線を挟んで略対向する位置に設けられていると共に、これら傾動支点部と作用点部との間の所定位置が前記押圧操作力の付与される力点部となっているという構成にした。 In order to achieve the above object, in the rotating electrical component of the present invention, a housing having a hollow bearing portion and an annular storage portion around the bearing portion, and an extrapolated rotation of the bearing portion. A hollow operating shaft supported so as to be capable of reciprocating in the axial direction, rotation detecting means disposed in the housing portion for detecting rotation information of the operating shaft, a tilting fulcrum portion, and an action point portion. And a drive body that is disposed in the storage portion and tilts by a pressing operation force in an axial direction with respect to the operation shaft, and a push that is disposed in the storage portion and is driven to be pressed by the action point portion of the drive body. A switch, and the tilting fulcrum part and the action point part of the drive body are provided at positions substantially opposite to each other across the rotation center line of the operation shaft, and the tilting fulcrum part and the action point part, The predetermined position between Was the configuration that has become a point portion to be given.

このように構成された回転型電気部品は、同一の操作軸で回転操作と押圧操作とを行えて操作性が良好であると共に、ハウジングの軸受部に包囲された内方空間を他の部品の収納スペースとして利用できるため、実装領域を拡大することなく多機能化を図ることができる。また、押圧操作時に操作軸が傾いた状態で押し込まれたとしても、押圧操作力が付与される駆動体の力点部の位置は不変なので、駆動体を常に同じ向きに傾動させることができ、それゆえ駆動体の作用点部によって同一のプッシュスイッチを確実に押圧駆動することができる。つまり、この回転型電気部品は、複数のプッシュスイッチを配設しなくても押圧操作時に確実にスイッチオン信号を出力させることができるため、押圧操作時に動作不良を起こしにくい高信頼性を実現しつつ、クリック感の重複が起こらない良好な操作感触を常に得られるようになっている。 The rotating electrical component configured in this way can perform a rotating operation and a pressing operation with the same operating shaft and has good operability, and the inner space surrounded by the bearing portion of the housing can be used for other components. Since it can be used as a storage space, multiple functions can be achieved without expanding the mounting area. In addition, even if the operating shaft is tilted during the pressing operation, the position of the force point of the driving body to which the pressing operating force is applied remains unchanged, so the driving body can always be tilted in the same direction. Therefore, the same push switch can be surely pressed and driven by the action point portion of the driver. In other words, this rotary electrical component can reliably output a switch-on signal during a pressing operation without providing a plurality of push switches, thus realizing high reliability that is unlikely to cause a malfunction during the pressing operation. On the other hand, it is possible to always obtain a good operation feeling that does not cause duplicate click feeling.

上記の構成において、押圧突起を有する押圧体を駆動体と操作軸との間に回転不能かつ軸線方向へ往復動可能に介在させ、該押圧突起を駆動体の力点部上に搭載しておけば、押圧体の押圧突起を介して押圧操作力を駆動体の所定位置（力点部）に確実に付与することができるため好ましい。 In the above configuration, a pressing body having a pressing protrusion is interposed between the driving body and the operation shaft so as not to rotate and to be reciprocable in the axial direction, and the pressing protrusion is mounted on the power point portion of the driving body. It is preferable because a pressing operation force can be reliably applied to a predetermined position (power point portion) of the driving body via the pressing protrusion of the pressing body.

この場合において、押圧体が一対の押圧突起を有するリング状に形成されていると共に、駆動体が作用点部から略等距離な２個所をそれぞれ力点部となしたリング状に形成されていると、押圧体や駆動体の形状を単純化できるため好ましい。そして、押圧体が周方向に略１８０度離れた２個所にそれぞれ押圧突起を有すると共に、駆動体が周方向に略１８０度離れた２個所をそれぞれ力点部となしている場合には、操作軸が傾いた状態で押し込まれたとしても、作動ストロークがほとんどばらつかなくなるため一層好ましい。また、これに加えて、押圧体の全体形状が点対称であると共に、傾動支点部と作用点部とが同形状で駆動体の全体形状が点対称であると、押圧体や駆動体の組み付け作業が容易に行えるため組立性が向上する。 In this case, the pressing body is formed in a ring shape having a pair of pressing protrusions, and the driving body is formed in a ring shape in which two points that are substantially equidistant from the action point portion are the force point portions, respectively. It is preferable because the shapes of the pressing body and the driving body can be simplified. When the pressing body has pressing protrusions at two locations that are approximately 180 degrees apart in the circumferential direction, and the driving body has two power spot portions at approximately 180 degrees in the circumferential direction, Even if it is pushed in a tilted state, it is more preferable because the operation stroke hardly varies. In addition to this, when the entire shape of the pressing body is point-symmetric, the tilting fulcrum portion and the action point portion are the same shape, and the entire shape of the driving body is point-symmetric, the assembly of the pressing body and the driving body. Assembling is improved because work can be easily performed.

また、上記の構成において、ハウジングの収納部が軸線方向に沿って第１収納部と第２収納部とに分割されていると共に、該ハウジングが、軸受部および第１収納部を有する第１のケースと、第１収納部の前方に配置される第２収納部を有する第２のケースとを一体化して構成されており、第１収納部にプッシュスイッチと駆動体および押圧体とが配設され、かつ第２収納部に回転検出手段が配設されていると、回転型電気部品が大径化せず組立性も向上するため好ましい。 Further, in the above configuration, the housing portion of the housing is divided into the first housing portion and the second housing portion along the axial direction, and the housing has a bearing portion and a first housing portion. The case and the second case having the second storage part disposed in front of the first storage part are integrally configured, and the push switch, the driving body, and the pressing body are provided in the first storage part. In addition, it is preferable that the rotation detecting means is disposed in the second storage portion because the rotating electrical component does not increase in diameter and the assemblability is improved.

また、上記の構成において、プッシュスイッチと駆動体の作用点部との間に弾性部材を介在させ、この弾性部材上に作用点部を搭載すれば、使用する弾性部材を適宜選択することによって押圧操作時の作動ストロークや作動力を容易に変更可能となる。 Further, in the above configuration, if an elastic member is interposed between the push switch and the action point portion of the driving body, and the action point portion is mounted on the elastic member, the pressing can be performed by appropriately selecting the elastic member to be used. The operating stroke and operating force during operation can be easily changed.

本発明の回転型電気部品は、同一の操作軸で回転操作と押圧操作とを行えて操作性が良好であると共に、ハウジングの軸受部に包囲された内方空間を他の部品の収納スペースとして利用できるため、実装領域を拡大することなく多機能化を図ることができる。また、押圧操作時に操作軸が傾いた状態で押し込まれたとしても、押圧操作力が付与される駆動体を常に同じ向きに傾動させることができるため、駆動体の作用点部によって同一のプッシュスイッチを確実に押圧駆動することができ、複数のプッシュスイッチを配設する必要がなくなる。それゆえ、この回転型電気部品は、押圧操作を確実に行えて信頼性が高いだけでなく、クリック感の重複が起こらないため操作感触が良好である。 The rotating electrical component of the present invention can perform a rotating operation and a pressing operation with the same operation shaft and has good operability, and the inner space surrounded by the bearing portion of the housing is used as a storage space for other components. Since it can be used, it is possible to achieve multiple functions without expanding the mounting area. In addition, even if the operating shaft is pushed in a tilted state during a pressing operation, the drive body to which the pressing operation force is applied can always be tilted in the same direction. Can be reliably driven by pressing, and there is no need to provide a plurality of push switches. Therefore, this rotary electric component not only has a high reliability because it can reliably perform a pressing operation, but also has a good operation feeling because there is no overlap in the click feeling.

A ring-shaped driving body 6 that is disposed in the first storage portion 1b and can be tilted, a ring-shaped pressing body 7 that is mounted on the driving body 6 and cannot be rotated and can reciprocate in the axial direction; 2 Conductive pattern 8 disposed on the inner bottom surface of the storage portion 2a, and an uneven cam on the front side 9a is formed and spline-coupled to the operation shaft 3, a pair of sliders 10 attached to the rear surface side of the rotating body 9, and a pair of rollers 11 and holding a pair of rollers 11 and elastically acting on the cam surface 9a. A pair of leaf springs 12 in contact with each other and an attachment member 13 to which the leaf springs 12 are attached to hold the first and second cases 1 and 2 are mainly configured.

第１のケース１と第２のケース２はいずれも樹脂成形品である。これら第１および第２のケース１，２は積層状態で一体化されてハウジングを構成しており、第１収納部１ｂの前方に第２収納部２ａが配置され、両収納部１ｂ，２ａが第２のケース２の底板部によって隔てられている。つまり、第１および第２のケース１，２を組み合わせて構成されるハウジングは、軸線方向に沿って第１収納部１ｂと第２収納部２ａとに分割された環状の収納部を有する。また、このハウジングは、軸受部１ａに包囲された内方空間（貫通孔１ｃ）がＬＥＤ等の他の部品の収納スペースとして利用できるようになっている。 Both the first case 1 and the second case 2 are resin molded products. The first and second cases 1 and 2 are integrated in a stacked state to form a housing, a second storage portion 2a is disposed in front of the first storage portion 1b, and both storage portions 1b and 2a are It is separated by the bottom plate part of the second case 2. That is, the housing formed by combining the first and second cases 1 and 2 has an annular storage portion that is divided into the first storage portion 1b and the second storage portion 2a along the axial direction. Further, in this housing, the inner space (through hole 1c) surrounded by the bearing portion 1a can be used as a storage space for other components such as LEDs.

第１のケース１には、貫通孔１ｃを有する軸受部１ａが第１収納部１ｂの内周縁に環状に立設されており、第１収納部１ｂの外周縁には低背な外壁部１ｄが環状に立設されている。軸受部１ａの外周面の基端側には、周方向に１８０度離れた２個所に回り止め突起１ｅが形成されている。また、図６に示すように、外壁部１ｄには、第２のケース２を位置決め状態で係止するするための４つの係止穴１ｆと、駆動体６を位置決めして回転を阻止するための一対の凹段部１ｇとが形成されている。第１収納部１ｂの内底面には駆動体６を支持する受け部１ｈが形成されていると共に、インサート成形技術によって固定接点１４が配設されており、固定接点１４から導出された出力端子１５が外壁部１ｄから後方へ突出している。なお、受け部１ｈと固定接点１４は周方向に１８０度離れた位置関係にある。また、第１収納部１ｂの内底面上には、固定接点１４と接離可能に対向するドーム状の可動接点板（メタルコンタクト）１６と、この可動接点板１６を覆う可撓性シート１７と、可撓性シート１７を介して可動接点板１６を覆うラバーシート５とが搭載されている。固定接点１４および可動接点板１６はプッシュスイッチ４を構成しており、このプッシュスイッチ４を可撓性シート１７で密閉することによって異物の侵入に起因する短絡や導通不良を未然に防止している。受け部１ｈ上には駆動体６の傾動支点部６ａが搭載され、ラバーシート５上には駆動体６の作用点部６ｂが搭載される。そして、この作用点部６ｂがラバーシート５を介してドーム状の可動接点板１６を所定量押し込むと、可動接点板１６が弾性的に反転して固定接点１４に当接し、出力端子１５からスイッチオン信号が出力されるようになっている。 In the first case 1, a bearing portion 1a having a through hole 1c is erected in an annular shape on the inner peripheral edge of the first storage portion 1b, and a low-profile outer wall portion 1d is provided on the outer peripheral edge of the first storage portion 1b. Is standing in an annular shape. On the base end side of the outer peripheral surface of the bearing portion 1a, anti-rotation protrusions 1e are formed at two positions 180 degrees apart in the circumferential direction. Further, as shown in FIG. 6, the outer wall portion 1d has four locking holes 1f for locking the second case 2 in a positioning state, and the driving body 6 for positioning and preventing rotation. A pair of concave steps 1g is formed. A receiving portion 1h for supporting the driving body 6 is formed on the inner bottom surface of the first storage portion 1b, and a fixed contact 14 is provided by an insert molding technique, and an output terminal 15 derived from the fixed contact 14 is provided. Protrudes rearward from the outer wall 1d. The receiving portion 1h and the fixed contact 14 are in a positional relationship that is 180 degrees apart in the circumferential direction. Further, on the inner bottom surface of the first storage portion 1b, a dome-shaped movable contact plate (metal contact) 16 facing the fixed contact 14 so as to be able to come into contact with and away from it, and a flexible sheet 17 covering the movable contact plate 16 are provided. A rubber sheet 5 that covers the movable contact plate 16 via the flexible sheet 17 is mounted. The fixed contact 14 and the movable contact plate 16 constitute a push switch 4, and the push switch 4 is sealed with a flexible sheet 17 to prevent a short circuit and poor conduction due to entry of foreign matter. . A tilting fulcrum portion 6a of the drive body 6 is mounted on the receiving portion 1h, and an action point portion 6b of the drive body 6 is mounted on the rubber sheet 5. When the action point portion 6b pushes the dome-shaped movable contact plate 16 through the rubber sheet 5 by a predetermined amount, the movable contact plate 16 is elastically reversed and comes into contact with the fixed contact 14 to switch from the output terminal 15 to the switch. An ON signal is output.

一方、第２のケース２には、第２収納部２ａの外周縁に外壁部２ｂが環状に立設されていると共に、底面の４個所に取付ボス２ｃが突設されている。また、導電パターン８から導出された出力端子１８が外壁部２ｂの一部から後方へ突出している。導電パターン８はインサート成形技術によって第２収納部２ａの内底面に配設されたエンコーダ用パターンであり、回転体９の回転に伴って摺動子１０が導電パターン８上を摺動するようになっている。なお、導電パターン８は外周側でコードパターンで内周側がコモンパターンである（図７参照）。この第２のケース２は、各取付ボス２ｃを対応する係止穴１ｆに挿入することによって、第１収納部１ｂを覆うように第１のケース１の外壁部１ｄ上に設置されている。 On the other hand, in the second case 2, an outer wall 2b is provided in an annular shape on the outer peripheral edge of the second storage portion 2a, and mounting bosses 2c are projected from four locations on the bottom surface. Further, the output terminal 18 led out from the conductive pattern 8 protrudes rearward from a part of the outer wall portion 2b. The conductive pattern 8 is an encoder pattern disposed on the inner bottom surface of the second storage portion 2a by an insert molding technique so that the slider 10 slides on the conductive pattern 8 as the rotating body 9 rotates. It has become. The conductive pattern 8 is a code pattern on the outer peripheral side and a common pattern on the inner peripheral side (see FIG. 7). The second case 2 is installed on the outer wall portion 1d of the first case 1 so as to cover the first storage portion 1b by inserting each mounting boss 2c into the corresponding locking hole 1f.

駆動体６は金属板を点対称なリング状にプレス加工したものである。この駆動体６には周方向に１８０度離れた２個所に、後方へ膨出する同形状の傾動支点部６ａと作用点部６ｂとが形成されている。また、駆動体６には傾動支点部６ａの近傍２個所と作用点部６ｂの近傍２個所にそれぞれフック状の係合片６ｃが形成されており、これら係合片６ｃが凹段部１ｇに挿入されているため、駆動体６は第１収納部１ｂ内で回転不能となっている。ただし、第１収納部１ｂ内で傾動支点部６ａが受け部１ｈ上に搭載されて作用点部６ｂがラバーシート５上に搭載されているため、駆動体６は傾動支点部６ａを支点として傾動可能であり、駆動体６を傾動させることによって作用点部６ｂでラバーシート５を押し撓めることができる。具体的には、操作軸３が軸線方向へ押圧操作されたときに、その押圧操作力が押圧体７を介して駆動体６の所定位置（力点部６ｄ）に付与されることにより、駆動体６が傾動するようになっている。この力点部６ｄは駆動体６の内周部で傾動支点部６ａおよび作用点部６ｂから等距離な位置に２個所設定されており、これら一対の力点部６ｄ上にそれぞれ押圧体７の押圧突起７ａが搭載されている。 The driving body 6 is obtained by pressing a metal plate into a point-symmetric ring shape. The drive body 6 is formed with tilting fulcrum portions 6a and action point portions 6b having the same shape that bulges backward at two locations 180 degrees apart in the circumferential direction. The drive body 6 is formed with hook-like engagement pieces 6c at two locations near the tilting fulcrum portion 6a and at two locations near the action point portion 6b. These engagement pieces 6c are formed on the concave step portion 1g. Since it is inserted, the drive body 6 is not rotatable in the first storage portion 1b. However, since the tilting fulcrum part 6a is mounted on the receiving part 1h and the action point part 6b is mounted on the rubber sheet 5 in the first storage part 1b, the driving body 6 tilts with the tilting fulcrum part 6a as a fulcrum. The rubber sheet 5 can be pushed and bent at the action point portion 6b by tilting the driving body 6. Specifically, when the operating shaft 3 is pressed in the axial direction, the pressing operation force is applied to a predetermined position (force point portion 6d) of the driving body 6 via the pressing body 7, whereby the driving body 6 is tilted. The force point portions 6d are set at two positions on the inner peripheral portion of the drive body 6 at equal distances from the tilting fulcrum portion 6a and the action point portion 6b, and the pressing protrusions of the pressing body 7 are respectively provided on the pair of force point portions 6d. 7a is mounted.

押圧体７は点対称なリング状の樹脂成形品である。この押圧体７の内壁部の後端側には、周方向に１８０度離れた２個所に切欠き７ｂが形成されている。第１収納部１ｂ内で各切欠き７ｂにはそれぞれ回り止め突起１ｅが係合可能に挿入されているため、押圧体７は回転不能となっている。また、押圧体７には各切欠き７ｂの近傍に径方向外側へせり出す耳部７ｃが突設されており、各耳部７ｃに後方へ突出する押圧突起７ａが形成されている。図５に示すように、これら一対の押圧突起７ａを駆動体６の一対の力点部６ｄ上に搭載した状態で、押圧体７は操作軸３と駆動体６との間に挟持されているため、この押圧体７は軸線方向へ往復動可能である。具体的には、操作軸３が押圧操作されると、押圧体７が後方へ移動して駆動体６を傾動させ、押圧操作力が取り除かれると、可動接点板１６やラバーシート５の復元力によって押圧体７および操作軸３が前方へ押し戻されるようになっている。 The pressing body 7 is a point-symmetric ring-shaped resin molded product. On the rear end side of the inner wall portion of the pressing body 7, notches 7 b are formed at two locations that are 180 degrees apart in the circumferential direction. Since the non-rotating protrusions 1e are inserted into the respective notches 7b in the first storage portion 1b so as to be engageable with each other, the pressing body 7 is not rotatable. Further, the pressing body 7 is provided with protruding ears 7c projecting radially outward in the vicinity of the notches 7b, and pressing protrusions 7a protruding rearward are formed on the respective ears 7c. As shown in FIG. 5, the pressing body 7 is sandwiched between the operation shaft 3 and the driving body 6 in a state where the pair of pressing protrusions 7 a are mounted on the pair of force point portions 6 d of the driving body 6. The pressing body 7 can reciprocate in the axial direction. Specifically, when the operating shaft 3 is pressed, the pressing body 7 moves backward to tilt the driving body 6, and when the pressing operation force is removed, the restoring force of the movable contact plate 16 and the rubber sheet 5. Thus, the pressing body 7 and the operation shaft 3 are pushed back forward.

操作軸３は略円筒状の樹脂成形品であり、軸受部１ａに外挿されて押圧体７上に搭載されている。この操作軸３は軸受部１ａの外周面に沿って回転可能かつ前後進可能であり、回転操作時には操作軸３にスプライン結合された回転体９が操作軸３と一体的に回転し、押圧操作時には操作軸３を搭載している押圧体７が操作軸３と一体的に前後進するようになっている。この操作軸３の外周面には、軸線方向に沿って延びるガイド部３ａと該ガイド部３ａよりも幅広で短寸な駆動部３ｂとが交互に複数形成されている。これらガイド部３ａと駆動部３ｂは操作軸３に外挿された回転体９の内壁部と係合しており、組立時にはガイド部３ａでガイドしながら回転体９を容易に操作軸３に組み付けることができ、操作軸３が回転操作されると、駆動部３ｂが回転体９に回転操作力を伝達するようになっている。また、操作軸３の外周面には複数個所に爪部３ｃが形成されている。これら爪部３ｃは、図示せぬつまみ部材を係止して該つまみ部材を操作軸３に装着させるためのものである。 The operation shaft 3 is a substantially cylindrical resin molded product, and is externally mounted on the bearing portion 1 a and mounted on the pressing body 7. The operating shaft 3 is rotatable and can move back and forth along the outer peripheral surface of the bearing portion 1a. During the rotating operation, the rotating body 9 splined to the operating shaft 3 rotates integrally with the operating shaft 3 to perform a pressing operation. Sometimes, the pressing body 7 carrying the operation shaft 3 moves forward and backward integrally with the operation shaft 3. On the outer peripheral surface of the operating shaft 3, a plurality of guide portions 3a extending along the axial direction and a plurality of driving portions 3b wider and shorter than the guide portions 3a are alternately formed. The guide portion 3a and the drive portion 3b are engaged with the inner wall portion of the rotating body 9 extrapolated to the operation shaft 3, and the rotating body 9 is easily assembled to the operation shaft 3 while being guided by the guide portion 3a during assembly. When the operation shaft 3 is rotated, the drive unit 3b transmits the rotation operation force to the rotating body 9. Further, claw portions 3 c are formed at a plurality of locations on the outer peripheral surface of the operation shaft 3. These claw portions 3 c are for locking a knob member (not shown) and attaching the knob member to the operation shaft 3.

回転体９はリング状の樹脂成形品であり、環状に突設された内壁部に幅狭ガイド溝９ｂと幅広ガイド溝９ｃが交互に複数形成されている。そして、幅狭ガイド溝９ｂにガイド部３ａを挿入して幅広ガイド溝９ｃに駆動部３ｂを挿入することによって、回転体９は操作軸３にスプライン結合されており、操作軸３が回転操作されると回転体９は一体的に回転するが、操作軸３が押圧操作されても回転体９は静止したままである。この回転体９の内壁部を包囲する環状のカム面９ａには凹凸が交互に形成されており、操作軸３が回転操作されると、回転体９が供回りして一対のローラ１１がカム面９ａ上を相対的に摺動するため、ローラ１１がカム面９ａに係脱して生起されるクリック感が操作者の手指に伝わるようになっている。また、回転体９の後面側には導電パターン８に弾接する一対の摺動子１０が保持されており、回転体９の回転に伴って摺動子１０が導電パターン８上を摺動するため、導電パターン８に対する摺動子１０の位置変化から回転体９の回転方向および回転角度が検出されるようになっている。すなわち、この回転型電気部品は、導電パターン８と回転体９と摺動子１０とによって操作軸３の回転情報を検出する回転検出手段が構成されている。 The rotating body 9 is a ring-shaped resin molded product, and a plurality of narrow guide grooves 9b and wide guide grooves 9c are alternately formed on an annular inner wall portion. Then, by inserting the guide portion 3a into the narrow guide groove 9b and inserting the drive portion 3b into the wide guide groove 9c, the rotating body 9 is splined to the operation shaft 3, and the operation shaft 3 is rotated. Then, the rotating body 9 rotates integrally, but the rotating body 9 remains stationary even when the operation shaft 3 is pressed. Concavities and convexities are alternately formed on the annular cam surface 9a surrounding the inner wall portion of the rotating body 9, and when the operating shaft 3 is rotated, the rotating body 9 rotates and the pair of rollers 11 cam. Since the roller 11 slides relatively on the surface 9a, the click feeling generated by the engagement of the roller 11 with the cam surface 9a is transmitted to the fingers of the operator. In addition, a pair of sliders 10 that elastically contact the conductive pattern 8 are held on the rear surface side of the rotating body 9, and the slider 10 slides on the conductive pattern 8 as the rotating body 9 rotates. The rotation direction and the rotation angle of the rotating body 9 are detected from the position change of the slider 10 with respect to the conductive pattern 8. That is, in this rotary electric component, a rotation detection means for detecting rotation information of the operation shaft 3 is constituted by the conductive pattern 8, the rotating body 9 and the slider 10.

板ばね１２は弾性に富む金属板（例えばステンレスやリン青銅等）からなり、略Ｃ字形状の一対の板ばね１２が回転体９のカム面９ａに対向して環状に配置されている。各板ばね１２は、両端部が取付部材１３の係合ピン部１３ａに係止されて環状天板部１３ｂに保持されており、中間部がローラ１１のシャフト１１ａを回転可能に保持している。そして、図４に示すように、一対の板ばね１２の弾性付勢力によって、周方向に１８０度離れて位置する一対のローラ１１が回転体９のカム面９ａに弾接している。それゆえ、回転体９の回転に伴ってローラ１１が凹凸のカム面９ａに係脱してクリック感が生起され、このクリック感によって操作者は回転操作量を把握できるようになっている。 The leaf spring 12 is made of an elastic metal plate (for example, stainless steel or phosphor bronze), and a pair of substantially C-shaped leaf springs 12 are arranged in an annular shape facing the cam surface 9 a of the rotating body 9. Each leaf spring 12 is held at the annular top plate portion 13b by engaging both ends thereof with the engagement pin portion 13a of the mounting member 13, and the intermediate portion rotatably holds the shaft 11a of the roller 11. . As shown in FIG. 4, the pair of rollers 11 positioned 180 degrees apart in the circumferential direction are elastically contacted with the cam surface 9 a of the rotating body 9 by the elastic biasing force of the pair of leaf springs 12. Therefore, as the rotating body 9 rotates, the roller 11 engages and disengages with the uneven cam surface 9a, and a click feeling is generated, and the operator can grasp the amount of rotation operation by this click feeling.

取付部材１３は金属板を打ち抜いて曲げ加工を施したものである。この取付部材１３には、複数の係合ピン部１３ａを有する環状天板部１３ｂと、環状天板部１３ｂの外周縁から後方へ延出する複数の係合脚片１３ｃおよび取付脚片１３ｄとが形成されている。環状天板部１３ｂは第２収納部２ａを覆うように第２のケース２の外壁部２ｂ上に配置されており、係合ピン部１３ａによって板ばね１２を保持している。また、図１に示すように、複数の係合脚片１３ｃは第１および第２のケース１，２を抱持して両ケース１，２を一体化している。なお、複数の取付脚片１３ｄは、この回転型電気部品が実装される図示せぬ配線基板に係止されるようになっている。 The attachment member 13 is obtained by punching a metal plate and bending it. The attachment member 13 includes an annular top plate portion 13b having a plurality of engagement pin portions 13a, and a plurality of engagement leg pieces 13c and attachment leg pieces 13d extending rearward from the outer peripheral edge of the annular top plate portion 13b. Is formed. The annular top plate portion 13b is disposed on the outer wall portion 2b of the second case 2 so as to cover the second storage portion 2a, and the leaf spring 12 is held by the engaging pin portion 13a. As shown in FIG. 1, the plurality of engaging leg pieces 13 c hold the first and second cases 1 and 2 and integrate the cases 1 and 2. The plurality of mounting leg pieces 13d are locked to a wiring board (not shown) on which the rotating electrical component is mounted.

このように構成された回転型電気部品は、操作軸３に装着された図示せぬつまみ部材に対して回転操作と押圧操作とが行われ、回転操作時には操作軸３が該つまみ部材と一体的に回転し、押圧操作時には操作軸３が該つまみ部材と一体的に軸線方向後方へ押し込まれる。 The rotary electric component configured as described above performs a rotation operation and a pressing operation on a knob member (not shown) mounted on the operation shaft 3, and the operation shaft 3 is integrated with the knob member during the rotation operation. When the pressing operation is performed, the operation shaft 3 is pushed rearward in the axial direction integrally with the knob member.

操作者がつまみ部材を介して操作軸３を回転操作すると、操作軸３にスプライン結合されている回転体９が供回りして摺動子１０が導電パターン８上を摺動するため、導電パターン８に対する摺動子１０の接触位置が変化して操作軸３の回転方向および回転角度が検出される。その際、ローラ１１がカム面９ａに係脱してクリック感が生起されるため、このクリック感によって操作者は回転操作量を把握することができる。 When the operator rotates the operation shaft 3 via the knob member, the rotating body 9 splined to the operation shaft 3 is provided and the slider 10 slides on the conductive pattern 8. The contact position of the slider 10 with respect to 8 changes, and the rotation direction and rotation angle of the operation shaft 3 are detected. At this time, since the roller 11 is engaged with and disengaged from the cam surface 9a and a click feeling is generated, the operator can grasp the rotation operation amount by the click feeling.

また、操作者がつまみ部材を介して操作軸３を押圧操作すると、操作軸３が後方へ移動して押圧体７を押し込むため、操作軸３と一体的に押圧体７が後方へ移動して押圧突起７ａが駆動体６を傾動させ、駆動体６の作用点部６ｂがラバーシート５を介してドーム状の可動接点板１６を押し込む。そして、作用点部６ｂが可動接点板１６を所定量押し込んだ時点で、可動接点板１６が反転して固定接点１４に当接するため、プッシュスイッチ４がオン動作して押圧操作が検出される。その際、可動接点板１６の反転動作に伴ってクリック感が生起されるため、このクリック感によって操作者は押圧操作が確実に行われたことを感得することができる。また、この後、押圧操作力が取り除かれると、可動接点板１６やラバーシート５の復元力によって、駆動体６が元の水平姿勢に戻ると共に押圧体７および操作軸３が前方へ押し戻される。 Further, when the operator presses the operating shaft 3 via the knob member, the operating shaft 3 moves rearward and pushes the pressing body 7, so that the pressing body 7 moves rearward integrally with the operating shaft 3. The pressing protrusion 7 a tilts the driving body 6, and the action point portion 6 b of the driving body 6 pushes the dome-shaped movable contact plate 16 through the rubber sheet 5. When the action point portion 6b pushes the movable contact plate 16 by a predetermined amount, the movable contact plate 16 is reversed and comes into contact with the fixed contact 14, so that the push switch 4 is turned on to detect the pressing operation. At that time, since a click feeling is generated in association with the reversing operation of the movable contact plate 16, the operator can feel that the pressing operation has been reliably performed by this click feeling. After that, when the pressing operation force is removed, the driving body 6 returns to the original horizontal posture and the pressing body 7 and the operation shaft 3 are pushed back by the restoring force of the movable contact plate 16 and the rubber sheet 5.

なお、操作軸３と軸受部１ａとの間には若干のクリアランスが必要なため、押圧操作時に操作軸３が斜めに傾いた状態で押し込まれることがあるが、その場合にも操作軸３と同じ向きに傾く押圧体７は常に押圧突起７ａが力点部６ｄを押し込むので、操作軸３がどの向きに傾いても駆動体６の傾動する向きは変わらず、作用点部６ｂがラバーシート５を押し込むことになる。 In addition, since a slight clearance is required between the operating shaft 3 and the bearing portion 1a, the operating shaft 3 may be pushed in an inclined state during a pressing operation. In the pressing body 7 inclined in the same direction, the pressing projection 7a always pushes the force point portion 6d. Therefore, the direction in which the driving body 6 tilts does not change regardless of the direction in which the operation shaft 3 is inclined, and the action point portion 6b pushes the rubber sheet 5. Will push.

以上説明したように本実施形態例に係る回転型電気部品は、同一の操作軸３で回転操作と押圧操作とを行えて操作性が良好であると共に、第１のケース１の軸受部１ａに包囲された内方空間（貫通孔１ｃ）をＬＥＤ等の他の部品の収納スペースとして利用できるため、実装領域を拡大することなく多機能化を図ったり照光性能を向上させることができる。また、この回転型電気部品は、押圧操作時に操作軸３が傾いた状態で押し込まれても、押圧操作力が付与される駆動体６の力点部６ｄの位置は不変なので、駆動体６を常に同じ向きに傾動させることができ、それゆえ駆動体６の作用点部６ｂによって同一のプッシュスイッチ４を確実に押圧駆動することができる。つまり、この回転型電気部品は、複数のプッシュスイッチを配設しなくても押圧操作時に確実にスイッチオン信号を出力させることができるため、押圧操作時に動作不良を起こしにくい高信頼性を実現しつつ、クリック感の重複が起こらない良好な操作感触が常に得られるようになっている。 As described above, the rotating electrical component according to the present embodiment can perform the rotating operation and the pressing operation with the same operation shaft 3 and has good operability, and the bearing portion 1a of the first case 1 has the operability. Since the enclosed inner space (through hole 1c) can be used as a storage space for other components such as LEDs, it is possible to achieve multiple functions and improve illumination performance without enlarging the mounting area. In addition, even if the rotary electric component is pushed in with the operation shaft 3 tilted during the pressing operation, the position of the force point portion 6d of the driving body 6 to which the pressing operation force is applied is not changed, so that the driving body 6 is always attached. They can be tilted in the same direction, and hence the same push switch 4 can be reliably driven to be pressed by the action point portion 6 b of the driving body 6. In other words, this rotary electrical component can reliably output a switch-on signal during a pressing operation without providing a plurality of push switches, thus realizing high reliability that is unlikely to cause a malfunction during the pressing operation. On the other hand, it is possible to always obtain a good operation feeling that does not cause duplicate click feeling.

また、本実施形態例では、操作軸３を搭載した押圧体７の押圧突起７ａを駆動体６の力点部６ｄ上に搭載しているため、押圧操作力を力点部６ｄに確実に付与することができる。しかも、押圧体７は周方向に１８０度離れた２個所に押圧突起７ａを有する点対称なリング状に形成されており、駆動体６は周方向に１８０度離れた２個所を力点部６ｄとなした点対称なリング状に形成されているため、この回転型電気部品は、押圧体７や駆動体６の形状が単純で両者６，７の組み付け作業も容易に行え、かつ、操作軸３が傾いた状態で押し込まれても、作動ストロークがほとんどばらつかないという利点を有する。ただし、押圧体７や駆動体６の形状は適宜選択可能であり、押圧体７を省略した構成にすることも可能である。 Further, in this embodiment, the pressing protrusion 7a of the pressing body 7 on which the operation shaft 3 is mounted is mounted on the power point portion 6d of the driving body 6, so that the pressing operation force is reliably applied to the power point portion 6d. Can do. In addition, the pressing body 7 is formed in a point-symmetric ring shape having pressing protrusions 7a at two positions 180 degrees apart in the circumferential direction, and the driving body 6 has two points 180 degrees apart in the circumferential direction as force point portions 6d. Since the rotary electric component is formed in a point-symmetric ring shape, the shape of the pressing body 7 and the driving body 6 is simple, the assembly work of both 6 and 7 can be easily performed, and the operation shaft 3 Even if it is pushed in a tilted state, there is an advantage that the operation stroke hardly varies. However, the shape of the pressing body 7 and the driving body 6 can be selected as appropriate, and the pressing body 7 can be omitted.

また、本実施形態例では、軸受部１ａおよび第１収納部１ｂを有する第１のケース１と、第１収納部１ｂの前方に配置される第２収納部２ａを有する第２のケース２とを一体化してハウジングを構成していると共に、第１収納部１ｂにプッシュスイッチ４と駆動体６および押圧体７とを配設し、かつ第２収納部２ａに導電パターン８や回転体９等の回転検出手段を配設しているため、回転型電気部品が大径化せず組立性も良好である。 In the present embodiment, the first case 1 having the bearing portion 1a and the first storage portion 1b, and the second case 2 having the second storage portion 2a disposed in front of the first storage portion 1b, And a push switch 4, a driving body 6, and a pressing body 7 are disposed in the first housing portion 1 b, and the conductive pattern 8, the rotating body 9, and the like are disposed in the second housing portion 2 a. Since the rotation detecting means is provided, the rotating electrical component does not have a large diameter and the assemblability is good.

また、本実施形態例では、プッシュスイッチ４と駆動体６の作用点部６ｂとの間に介在したラバーシート５上に該作用点部６ｂを搭載しているため、使用するラバーシート５を適宜選択することによって押圧操作時の作動ストロークや作動力を容易に変更することができる。なお、ラバーシート以外の弾性部材を使用することも可能である。 In this embodiment, since the action point portion 6b is mounted on the rubber sheet 5 interposed between the push switch 4 and the action point portion 6b of the driving body 6, the rubber sheet 5 to be used is appropriately selected. By selecting, the operation stroke and the operation force at the time of pressing operation can be easily changed. An elastic member other than the rubber sheet can also be used.
