Description

本発明は、入力装置、及び、該入力装置を備えた電子機器に関するものである。 The present invention relates to an input device and an electronic apparatus including the input device.

従来、入力装置として、回転操作用の操作体と、操作体の下面に、回転中心を合わせて同心に取り付けられ、複数極に着磁されたリング状磁石と、操作体を回転自在に支持する基台と、操作体の回転操作に伴うリング状磁石の回転を非接触で検出する検出素子と、リング状磁石に対向するよう基台に取り付けられ、リング状磁石との間で吸引反発力を発生して操作感触を発生させる磁性体と、操作体の円形中央孔内に配置され、押込操作可能な操作ボタンと、を備えた構成のものが公知である（例えば、特許文献１参照）。 Conventionally, as an input device, an operation body for rotational operation, a ring-shaped magnet that is concentrically mounted on the lower surface of the operation body with the center of rotation aligned, and supports the operation body rotatably. A base, a detection element that detects the rotation of the ring-shaped magnet associated with the rotation operation of the operating body in a non-contact manner, and a base that is attached to the base so as to face the ring-shaped magnet.

しかしながら、前者の入力装置では、操作ボタンからさらに外径側に突出した鍔部の外周面が基台の内筒部にガイドされるように構成されている。このため、あまり操作ボタンの外径寸法を大きくすると、押込操作する際に傾きやすくなり、安定した動作が得られないという問題がある。 However, the former input device is configured such that the outer peripheral surface of the flange protruding further outward from the operation button is guided by the inner cylindrical portion of the base. For this reason, if the outer diameter of the operation button is made too large, there is a problem that it is easy to incline during the push-in operation and a stable operation cannot be obtained.

一方、後者の入力装置では、押しボタンスイッチを構成する外周面（さらに外径側に突出した環状リブの外周面を含む）をガイドするようにしている。このため、押しボタンスイッチの操作面積を大きく取ろうとすれば、プリント基板に対する押しボタンスイッチの占有面積を大きくしなければならなくなり、他の電子部品（検出部）を実装可能な領域が制約を受けるという問題がある。 On the other hand, in the latter input device, the outer peripheral surface (including the outer peripheral surface of the annular rib protruding to the outer diameter side) constituting the push button switch is guided. For this reason, if the operation area of the push button switch is to be increased, the area occupied by the push button switch with respect to the printed circuit board must be increased, and the area where other electronic components (detection units) can be mounted is restricted. There is a problem.

そこで、本発明は、操作性を高めつつ、操作部分の外径寸法を大きくし、しかもガイド部分での専有面積を小さくすることのできる入力装置、及び、該入力装置を備えた電子機器を提供することを課題とする。 Accordingly, the present invention provides an input device capable of increasing the outer diameter size of the operation portion and reducing the exclusive area of the guide portion while improving operability, and an electronic apparatus including the input device. The task is to do.

（構成）
図１及び図２は、本実施形態に係る入力装置１を示す。この入力装置１は、図３及び図４に示すように、ベースであるプリント基板２と、第１操作部材である回転ダイアル３と、第２操作部材である押ボタン４と、プリント基板２に実装された検出部材５と、プリント基板２に装着される中間部材６とを備える。 (Constitution)

As shown in FIGS. 3 and 4, the input device 1 includes a printed circuit board 2 that is a base, a rotary dial 3 that is a first operation member, a push button 4 that is a second operation member, and a printed circuit board 2. A mounted detection member 5 and an intermediate member 6 mounted on the printed circuit board 2 are provided.

プリント基板２（例えば、ガラスエポキシ基板（ＦＲ４））は、平面視略円形状の検出部７と、この検出部７の両側縁部からそれぞれ延びるリード部８とからなる。プリント基板２の上面には、プリント配線が形成され、又、後述する検出部材５が実装されている。但し、プリント基板２とは別にベースを設けることも可能である（この場合、プリント基板２が検出部材５となる。）。 The printed circuit board 2 (for example, a glass epoxy board (FR4)) includes a detection unit 7 having a substantially circular shape in plan view, and lead portions 8 extending from both side edges of the detection unit 7. Printed wiring is formed on the upper surface of the printed circuit board 2, and a detection member 5 described later is mounted. However, it is also possible to provide a base separately from the printed circuit board 2 (in this case, the printed circuit board 2 serves as the detection member 5).

検出部７には、外周側の４箇所に取付孔９が周方向に等ピッチでそれぞれ形成され、外周側の２箇所の対称位置に第１位置決め孔１０がそれぞれ形成されている。また、検出部７の上面には被覆シート１１が貼着されるようになっている。被覆シート１１は、プリント基板２の上面（リード部８を除く円形部分：検出部７）を覆う平面視略円形状に形成されている。そして、被覆シート１１には、プリント基板２の取付孔９に対応する位置４箇所に逃がし孔１２が、第１位置決め孔１０に対応する位置２箇所に第２位置決め孔１３がそれぞれ形成されている。逃がし孔１２のうちの２箇所は、内周側に広げられ、後述するホール素子３３との干渉が回避されている。また、被覆シート１１には、後述する接点部に対応する位置に、ドーム状に膨出する金属製薄板（ゴム等でもよい）からなる反転バネ１４（図４参照）が一体化され、接点部をオン・オフするスイッチ部を構成している。反転バネ１４によって形成された中央部の窪みからは２箇所に空気逃がし溝１５が形成されている。また、周囲４箇所の窪みは、２箇所ずつ空気逃がし溝１５によって連通されている。 In the detection portion 7, mounting holes 9 are formed at four positions on the outer peripheral side at an equal pitch in the circumferential direction, and first positioning holes 10 are formed at two symmetrical positions on the outer peripheral side. A covering sheet 11 is attached to the upper surface of the detection unit 7. The covering sheet 11 is formed in a substantially circular shape in plan view covering the upper surface of the printed circuit board 2 (circular portion excluding the lead portion 8: the detecting portion 7). In the covering sheet 11, relief holes 12 are formed at four positions corresponding to the mounting holes 9 of the printed circuit board 2, and second positioning holes 13 are formed at two positions corresponding to the first positioning holes 10. . Two of the escape holes 12 are widened to the inner peripheral side, and interference with the Hall element 33 described later is avoided. Further, the cover sheet 11 is integrated with a reversing spring 14 (see FIG. 4) made of a thin metal plate (such as rubber) that bulges in a dome shape at a position corresponding to a contact portion described later. The switch part which turns ON / OFF is comprised. Air escape grooves 15 are formed at two locations from the central recess formed by the reversing spring 14. In addition, the four depressions around the periphery are communicated with each other by two air escape grooves 15.

回転ダイアル３は、合成樹脂材料を成形加工することにより略円筒状としたものである。 The rotary dial 3 is formed into a substantially cylindrical shape by molding a synthetic resin material.

回転ダイアル３の中心には開口部１６が形成されている。開口部１６は、図５に示すように、開口縁部から下方に向かう外側内周壁１７と、この外側内周壁１７の下端から内径側に延びるドーナツ状の底面部１８と、この底面部１８の内周縁から上下に延びる内側内周壁１９とで構成されている。内側内周壁１９は、上方から下方に向かうに従って徐々に内径寸法が小さくなるように形成されている。そして、内側内周壁１９の下端部が後述する中間部材６の小径部４４に回転可能に支持されるようになっている。なお、外側内周壁１７、底面部１８及び内側内周壁１９で囲まれた環状溝は内側貯留部２０である。内側貯留部２０は、外部から流入した液体等がそれ以上内部に侵入することを防止する。また、回転ダイアル３の外周壁３ａは、下端開口縁部が外周面に沿うように延設され、環状溝が形成されている。この環状溝が外側貯留部２１であり、入力装置１を電子機器に組み込んだ際に、電子機器内への液体等の侵入を防止するように機能する。 An opening 16 is formed at the center of the rotary dial 3. As shown in FIG. 5, the opening 16 includes an outer inner peripheral wall 17 that extends downward from the opening edge, a donut-shaped bottom surface 18 that extends from the lower end of the outer inner peripheral wall 17 toward the inner diameter side, and the bottom surface 18. It is comprised by the inner inner peripheral wall 19 extended up and down from an inner peripheral edge. The inner inner peripheral wall 19 is formed such that the inner diameter dimension gradually decreases from the upper side toward the lower side. And the lower end part of the inner side inner peripheral wall 19 is rotatably supported by the small diameter part 44 of the intermediate member 6 mentioned later. An annular groove surrounded by the outer inner peripheral wall 17, the bottom surface portion 18, and the inner inner peripheral wall 19 is an inner storage portion 20. The inner reservoir 20 prevents liquid or the like flowing from the outside from entering the interior further. Further, the outer peripheral wall 3a of the rotary dial 3 is extended so that the lower end opening edge is along the outer peripheral surface, and an annular groove is formed. This annular groove is the outer storage portion 21 and functions to prevent intrusion of liquid or the like into the electronic device when the input device 1 is incorporated into the electronic device.

回転ダイアル３の上面には、周方向に所定ピッチで大小１箇所ずつ複数の突起３ｂがそれぞれ形成されている。これら突起３ｂは、回転ダイアル３を指操作で回転操作させる際の抵抗として作用し、スムーズな回転動作を実現する。 On the upper surface of the rotary dial 3, a plurality of protrusions 3 b are formed at a predetermined pitch in the circumferential direction, one at a location. These protrusions 3b act as a resistance when the rotary dial 3 is rotated by a finger operation, thereby realizing a smooth rotating operation.

回転ダイアル３の外周壁３ａと外側内周壁１７との間には、図４に示すように、両壁面の中間に位置する環状リブ２２と、周方向に等ピッチで配置される複数の放射状リブ２３とが形成されている。これらリブにより、樹脂量を抑制し、成形後のヒケ等の不具合を防止すると共に、所望の強度が得られるようになっている。放射状リブ２３の内周側には段部２３ａが形成され、そこには両面テープ２４を介して環状マグネット２５が貼着されるようになっている。環状マグネット２５は、Ｎ極とＳ極が環状に交互に出現するようにしたもので、ここでは１６極のもの（Ｎ極が８箇所に出現し、Ｓ極が８箇所に出現する８個の磁石を環状に一体化したもの）が使用されている。 Between the outer peripheral wall 3a and the outer inner peripheral wall 17 of the rotary dial 3, as shown in FIG. 4, an annular rib 22 located in the middle of both wall surfaces and a plurality of radial ribs arranged at equal pitches in the circumferential direction. 23 is formed. These ribs suppress the amount of resin, prevent defects such as sink marks after molding, and obtain desired strength. A step portion 23 a is formed on the inner peripheral side of the radial rib 23, and an annular magnet 25 is attached thereto via a double-sided tape 24. The annular magnet 25 is configured so that the N pole and the S pole appear alternately in a ring shape. Here, the one having 16 poles (the N poles appear at 8 locations and the S poles appear at 8 locations) A magnet in which the magnets are integrated in a ring shape) is used.

押ボタン４は、図３に示すように、操作部２６と軸部２７とで構成されている。操作部２６は、円盤状で、回転ダイアル３の開口部１６に配置される。操作部２６の下面には段部２６ａが形成されている。段部２６ａは、その下面で弾性シート２８を回転ダイアル３の内側内周壁１９の上端部との間に挟持する。軸部２７の下端面中央部には押圧突部２９が形成され、後述する第１スイッチ部３１を押込可能となっている。また、軸部２７の下端側外周面には対称な位置２箇所に係止突部３０がそれぞれ形成されている。なお、弾性シート２８はポリエチレン等の柔軟性を有する材料からなり、そこには押ボタン４の軸部２７と係止突部３０が挿通可能な開口部２８ａが形成されている。 As shown in FIG. 3, the push button 4 includes an operation unit 26 and a shaft unit 27. The operation unit 26 has a disk shape and is disposed in the opening 16 of the rotary dial 3. A step portion 26 a is formed on the lower surface of the operation portion 26. The step portion 26 a holds the elastic sheet 28 between the lower surface thereof and the upper end portion of the inner inner peripheral wall 19 of the rotary dial 3. A pressing projection 29 is formed at the central portion of the lower end surface of the shaft portion 27 so that a first switch portion 31 described later can be pushed in. Further, locking projections 30 are formed at two symmetrical positions on the outer peripheral surface of the lower end side of the shaft portion 27, respectively. The elastic sheet 28 is made of a flexible material such as polyethylene, and an opening 28a through which the shaft portion 27 and the locking projection 30 of the push button 4 can be inserted is formed.

検出部材５は、前記プリント基板２に実装される第１スイッチ部３１、第２スイッチ部３２、及び、ホール素子３３からなる。第１スイッチ部３１は、プリント基板２の中央部に設けられる第１接点部３４と、この第１接点部３４を覆う被覆シート１１、詳しくはドーム状の反転バネ１４を一体化した部分とで構成されている。第２スイッチ部３２は、プリント基板２の外周側４箇所に設けられる第２接点部３５と、各第２接点部３５を覆う反転バネ１４とで構成されている。ホール素子３３は、第１スイッチ部３１を挟んで対称な位置にそれぞれ配置されている。 The detection member 5 includes a first switch part 31, a second switch part 32, and a hall element 33 that are mounted on the printed circuit board 2.

円盤部３６には４箇所等分で円筒部３７から延びる弾性腕部３８がそれぞれ形成されている。各弾性腕部３８の先端には上下に突出する突起３９ａ、３９ｂがそれぞれ形成されている。上方側の突起３９ａが回転ダイアル３のリブに当接して押し込まれ、下方側の突起３９ｂが第２スイッチ部３２を押し込む。 The disk portion 36 is formed with elastic arm portions 38 extending from the cylindrical portion 37 in four equal portions. Protrusions 39a and 39b projecting upward and downward are formed at the tips of the elastic arm portions 38, respectively. The upper protrusion 39 a is pushed in contact with the rib of the rotary dial 3, and the lower protrusion 39 b pushes the second switch portion 32.

また、円盤部３６には弾性腕部３８とは４５度ずれた位置４箇所に等分で、上方側に支持用突部４０が、下方側に係止部４１がそれぞれ突出している。支持用突部４０は、前記弾性腕部３８の上方側の突起３９ａに比べて円盤部３６の上面からの突出寸法が若干小さく、回転ダイアル３を押し込む際の押し込み過ぎを防止するストッパとしての役割を果たす。係止部４１は、二股に分かれた各弾性片４１ａの先端外面に係止爪４１ｂをそれぞれ形成されている。係止部４１は、各弾性片４１ａを近接させるように弾性変形させてプリント基板２に形成した取付孔９に挿通され、係止爪４１ｂが通過することにより形状復帰して係止される。これにより、中間部材６はプリント基板２に一体化される。但し、係止部４１に代えてカシメ固定可能な構成とすることも可能である。係止部４１が突出する部分を含む所定領域には矩形凹部４２が形成されている。矩形凹部４２は、プリント基板２に実装したホール素子３３との干渉を回避する。中間部材６とプリント基板２の間には、プリント基板２の上面に貼着した被覆シート１１が介在し、その弾性により両部材間のがたつきが防止される。 Further, the disk portion 36 is equally divided into four positions shifted by 45 degrees from the elastic arm portion 38, and a support protrusion 40 protrudes upward and a locking portion 41 protrudes downward. The supporting protrusion 40 has a slightly smaller protruding dimension from the upper surface of the disk portion 36 than the protrusion 39 a on the upper side of the elastic arm portion 38, and serves as a stopper that prevents excessive pressing when the rotary dial 3 is pressed. Fulfill. The locking part 41 is formed with a locking claw 41b on the outer surface of the tip of each elastic piece 41a divided into two parts. The locking portion 41 is elastically deformed so that the elastic pieces 41a are brought close to each other and is inserted into the mounting hole 9 formed in the printed circuit board 2, and the shape is restored and locked when the locking claw 41b passes. Thereby, the intermediate member 6 is integrated with the printed circuit board 2. However, it is also possible to adopt a configuration that can be caulked and fixed instead of the locking portion 41. A rectangular recess 42 is formed in a predetermined area including a portion from which the locking portion 41 protrudes. The rectangular recess 42 avoids interference with the Hall element 33 mounted on the printed circuit board 2. Between the intermediate member 6 and the printed circuit board 2, there is a covering sheet 11 adhered to the upper surface of the printed circuit board 2, and rattling between the two members is prevented by its elasticity.

円筒部３７は、大径部４３と、その上面中央部から突出する小径部４４とからなる段付き形状である。小径部４４は、回転ダイアル３の開口部１６（内側内周壁１９）に配置され、回転ダイアル３を回転自在に支持する。詳しくは、回転ダイアル３の内側内周壁１９の内周面のうち、下端部が支持され、その上方部分は非接触である。したがって、回転ダイアル３を位置ずれすることなく回転可能に支持しつつ、上面外周部のいずれかを押し込めば、回転ダイアル３が傾いて押し込み操作可能となる。なお、例えば、小径部４４を上端に向かうに従って徐々に外径寸法が小さくなるように構成し、内側内周壁１９を同一内径寸法で構成することも可能である。要は、回転ダイアル３を回転かつ外周部を押し込み可能に支持可能であればよい。また、大径部４３の上面には回転ダイアル３の内側内周壁１９の下端部が非接触となるように構成されている。これにより、回転ダイアル３を回転操作した際の操作性が高められている。 The cylindrical portion 37 has a stepped shape including a large-diameter portion 43 and a small-diameter portion 44 that protrudes from the center of the upper surface thereof. The small diameter portion 44 is disposed in the opening 16 (inner inner peripheral wall 19) of the rotary dial 3, and rotatably supports the rotary dial 3. Specifically, the lower end portion of the inner peripheral surface of the inner inner peripheral wall 19 of the rotary dial 3 is supported, and the upper portion thereof is non-contact. Therefore, if one of the outer peripheral portions of the upper surface is pushed in while rotatably supporting the rotary dial 3 without being displaced, the rotary dial 3 can be pushed in and tilted. For example, it is possible to configure the small-diameter portion 44 so that the outer diameter dimension gradually decreases toward the upper end, and to configure the inner inner peripheral wall 19 with the same inner diameter dimension. In short, it is sufficient if the rotary dial 3 can be supported so that the rotary dial 3 can be rotated and the outer peripheral portion can be pushed in. Further, the upper surface of the large-diameter portion 43 is configured such that the lower end portion of the inner inner peripheral wall 19 of the rotary dial 3 is not in contact. As a result, the operability when the rotary dial 3 is rotated is enhanced.

また、円筒部３７は、その中心に形成された円形孔４５によって上下面が連通し、押ボタン４の軸部２７が隙間無く挿通するガイド部となっている。円形孔４５を構成する内周面の２箇所には、押ボタン４の各係止突部３０が挿通する溝部４６がそれぞれ形成されている。円筒部３７の底面側には、小径部４４の下端開口縁に沿って一端側の溝部４６から所定角度の範囲で凹所４７が形成されている。凹所４７の他端側にはガイド凹部４８が形成され、押ボタン４の各係止突部３０が上下動可能にガイドされるようになっている。ガイド凹部４８の凹所４７からの深さは、押ボタン４の押込動作範囲をカバーするのに十分な深さである。 The cylindrical portion 37 is a guide portion through which the upper and lower surfaces communicate with each other through a circular hole 45 formed at the center thereof, and the shaft portion 27 of the push button 4 is inserted without a gap. Groove portions 46 through which the respective locking projections 30 of the push button 4 are inserted are formed at two locations on the inner peripheral surface constituting the circular hole 45. On the bottom surface side of the cylindrical portion 37, a recess 47 is formed within a predetermined angle range from the groove portion 46 on one end side along the lower end opening edge of the small diameter portion 44. A guide recess 48 is formed on the other end side of the recess 47, and each locking projection 30 of the push button 4 is guided so as to be movable up and down. The depth of the guide recess 48 from the recess 47 is sufficient to cover the pressing operation range of the push button 4.

（組立方法）
続いて、前記構成の入力装置１の組立方法について説明する。 (Assembly method)
Next, a method for assembling the input device 1 having the above-described configuration will be described.

まず、予め検出部材５を実装したプリント基板２を図示しない治具に取り付け、プリント基板２の上面に被覆シート１１を貼着する。このとき、治具に固定した位置決めピンを、プリント基板２の第１位置決め孔１０と、被覆シート１１の第２位置決め孔１３とに挿通し、治具に対してプリント基板２と被覆シート１１とを位置決めする。 First, the printed circuit board 2 on which the detection member 5 is mounted in advance is attached to a jig (not shown), and the covering sheet 11 is attached to the upper surface of the printed circuit board 2. At this time, the positioning pin fixed to the jig is inserted into the first positioning hole 10 of the printed board 2 and the second positioning hole 13 of the covering sheet 11, and the printed board 2 and the covering sheet 11 are inserted into the jig. Positioning.

一方、回転ダイアル３の下面側、詳しくは、放射状リブ２３に形成された段部２３ａに両面テープ２４を介して環状マグネット２５を貼着する。そして、環状マグネット２５を貼着した回転ダイアル３を中間部材６の上方に配置する。これにより、回転ダイアル３の開口部１６（内側内周壁１９）が中間部材６の小径部４４によって回転可能に支持される。 On the other hand, an annular magnet 25 is attached to the lower surface side of the rotary dial 3, specifically, to a step portion 23 a formed on the radial rib 23 via a double-sided tape 24. Then, the rotary dial 3 to which the annular magnet 25 is attached is disposed above the intermediate member 6. Thereby, the opening 16 (inner inner peripheral wall 19) of the rotary dial 3 is rotatably supported by the small diameter portion 44 of the intermediate member 6.

次いで、回転ダイアル３の開口部１６を介して中間部材６に押ボタン４を装着し、回転ダイアル３と中間部材６とを、前述の回転可能な状態に維持したままで一体化する。すなわち、押ボタン４の軸部２７には予め弾性シート２８を取り付けておく。押ボタン４の軸部２７を、回転ダイアル３を回転可能に支持させた中間部材６の円形孔４５に挿通する。このとき、押ボタン４の係止突部３０を円形孔４５の溝部４６に位置合わせする。中間部材６に対して押ボタン４を押し込み、係止突部３０を中間部材６の下面側に突出させる。中間部材６に対して相対的に押ボタン４を回転させ、係止突部３０を、凹所４７を介してガイド凹部４８へと移動させる。押ボタン４には、その操作部２６の下面と、回転ダイアル３の内側内周壁１９との間に挟持させた弾性シート２８による付勢力が作用している。したがって、押ボタン４は、その係止突部３０が凹所４７からガイド凹部４８に至ると、このガイド凹部４８の底面に当接するまで押し上げられる。この状態では、押ボタン４は、その軸部２７の外周面を中間部材６の円形孔４５の内周面によって、軸方向の広い範囲でガイドされる。 Next, the push button 4 is attached to the intermediate member 6 through the opening 16 of the rotary dial 3, and the rotary dial 3 and the intermediate member 6 are integrated while maintaining the above-described rotatable state. That is, the elastic sheet 28 is attached to the shaft portion 27 of the push button 4 in advance. The shaft portion 27 of the push button 4 is inserted into the circular hole 45 of the intermediate member 6 that rotatably supports the rotary dial 3. At this time, the locking protrusion 30 of the push button 4 is aligned with the groove 46 of the circular hole 45. The push button 4 is pushed into the intermediate member 6, and the locking protrusion 30 is protruded to the lower surface side of the intermediate member 6. The push button 4 is rotated relative to the intermediate member 6 to move the locking projection 30 to the guide recess 48 via the recess 47. The push button 4 is subjected to a biasing force by an elastic sheet 28 sandwiched between the lower surface of the operation portion 26 and the inner inner peripheral wall 19 of the rotary dial 3. Therefore, when the locking projection 30 reaches the guide recess 48 from the recess 47, the push button 4 is pushed up until it comes into contact with the bottom surface of the guide recess 48. In this state, the push button 4 is guided in a wide range in the axial direction by the outer peripheral surface of the shaft portion 27 by the inner peripheral surface of the circular hole 45 of the intermediate member 6.

その後、被覆シート１１を貼着したプリント基板２に、環状マグネット２５及び回転ダイアル３を取り付けた中間部材６を装着する。ここでは、中間部材６の係止部４１をプリント基板２の取付孔９に挿通し、係止爪を係止することにより装着状態を得ている。この状態では、プリント基板２に貼着した被覆シート１１の弾性力により、プリント基板２と中間部材６の間にがたつきが発生することはない。また、プリント基板２及び被覆シート１１によって得られた第１スイッチ部３１に押ボタン４の押圧突部２９の下端が当接（又は近傍に位置）し、第２スイッチ部３２に弾性腕部３８の下方側の突起３９ｂの下端が当接（又は近傍に位置）する。弾性腕部３８の上方側の突起３９ａは回転ダイアル３のリブに当接（又は近傍に位置）する。また、支持用突部４０がリブに当接し、回転ダイアル３の回転状態を安定させる。これにより、入力装置１が完成する。 Thereafter, the intermediate member 6 to which the annular magnet 25 and the rotary dial 3 are attached is mounted on the printed circuit board 2 to which the covering sheet 11 is adhered. Here, the mounting state is obtained by inserting the locking portion 41 of the intermediate member 6 into the mounting hole 9 of the printed circuit board 2 and locking the locking claw. In this state, the backlash between the printed circuit board 2 and the intermediate member 6 does not occur due to the elastic force of the covering sheet 11 adhered to the printed circuit board 2. Further, the lower end of the pressing protrusion 29 of the push button 4 abuts (or is located near) the first switch portion 31 obtained by the printed circuit board 2 and the covering sheet 11, and the elastic arm portion 38 contacts the second switch portion 32. The lower end of the projection 39b on the lower side of this is in contact (or located in the vicinity). The protrusion 39 a on the upper side of the elastic arm portion 38 abuts on (or is located near) the rib of the rotary dial 3. Further, the support protrusions 40 come into contact with the ribs and stabilize the rotation state of the rotary dial 3. Thereby, the input device 1 is completed.

（動作）
次に、前記入力装置１の動作について説明する。 (Operation)
Next, the operation of the input device 1 will be described.

回転ダイアル３の環状の上面に指を載せ、回転方向（正逆いずれの回転でも可）の力を作用させると、回転ダイアル３は、内側内周壁１９の下端部を中間部材６の小径部４４にガイドされて回転する。また、回転ダイアル３は、下面すなわちリブを中間部材６の支持用突部４０によってガイドされる。このため、回転ダイアル３の回転状態は安定している。また、回転ダイアル３の回転により、この回転ダイアル３に一体化した環状マグネット２５も回転する。そして、環状マグネット２５の回転に伴って変化する磁界がホール素子３３によって検出され、回転ダイアル３の回転方向及び回転量が演算される。 When a finger is placed on the annular upper surface of the rotary dial 3 and a force in the rotation direction (either forward or reverse rotation is allowed) is applied, the rotary dial 3 causes the lower end portion of the inner inner peripheral wall 19 to be connected to the small diameter portion 44 of the intermediate member 6. It is guided and rotated. Further, the rotary dial 3 is guided by the supporting protrusions 40 of the intermediate member 6 on the lower surface, that is, the rib. For this reason, the rotation state of the rotary dial 3 is stable. Further, as the rotary dial 3 rotates, the annular magnet 25 integrated with the rotary dial 3 also rotates. And the magnetic field which changes with rotation of the annular magnet 25 is detected by the Hall element 33, and the rotation direction and rotation amount of the rotary dial 3 are calculated.

回転ダイアル３の外周部のうち、図２中、上下左右のいずれかを押し込めば、対応する位置に設けた弾性腕部３８が、その先端の上方側の突起３９ａを介して弾性変形し、下方側の突起３９ｂが第２スイッチ部３２を押し込んでオン状態とする。 If one of the upper, lower, left and right sides of the outer peripheral portion of the rotary dial 3 is pushed in, the elastic arm portion 38 provided at the corresponding position is elastically deformed via the protrusion 39a on the upper side of the tip, and The side protrusion 39b pushes in the second switch part 32 to turn it on.

また、押ボタン４を押込操作すると、その下端に設けた押圧突部２９が第１スイッチ部３１を押し込んでオン状態とする。押ボタン４の押込操作では、操作部２６の操作面積が大きく操作しやすいだけでなく、軸部２７の外周面を中間部材６のガイド部である円形孔４５の内周面にガイドされて傾くことなく安定した状態で上下動する。 Further, when the push button 4 is pushed in, the push protrusion 29 provided at the lower end pushes the first switch portion 31 to turn it on. In the push-in operation of the push button 4, not only the operation area of the operation portion 26 is large and easy to operate, but also the outer peripheral surface of the shaft portion 27 is inclined by being guided by the inner peripheral surface of the circular hole 45 that is the guide portion of the intermediate member 6. It moves up and down in a stable state without any problems.

前記入力装置１は、例えば、テレビやＤＶＤプレーヤ等のリモコン、デジタルカメラ、携帯電話等の各種電子機器に組み込んで使用することができる。 The input device 1 can be used by being incorporated into various electronic devices such as a remote controller such as a television or a DVD player, a digital camera, and a mobile phone.

例えば、テレビのリモコンに組み込んだ場合、回転ダイアル３を正逆回転操作することにより、ディスプレイに表示させた番組表で、ハイライト表示させる番組を、予め決められた順序又は逆順序で変更することができる。また、回転ダイアル３の上下左右のいずれかを押込操作することによっても、番組表でハイライト表示させる番組を上下左右に移動させることができる。そして、押ボタン４を押込操作することにより、ハイライト表示させた番組を選択してディスプレイに表示させたり、ハードディスクビデオレコーダ等が接続されていれば、予約録画できるように設定したりすることが可能である。 For example, when incorporated in a TV remote control, the program to be highlighted can be changed in a predetermined or reverse order by performing a forward / reverse rotation operation of the rotary dial 3 in the program table displayed on the display. Can do. The program to be highlighted in the program guide can also be moved up, down, left, and right by pushing one of up, down, left and right of the rotary dial 3. Then, by pressing the push button 4, the highlighted program can be selected and displayed on the display, or if a hard disk video recorder or the like is connected, it can be set so that it can be reserved for recording. Is possible.

なお、電子機器では、使用環境により、コーヒー等の液体がかかる恐れがあり、この液体が構成部品の隙間から内部に侵入すると、誤動作や、場合によっては故障の原因となる。このため、この侵入を的確に防止しなければならない。また、同様の理由で、空気中の埃等の内部への侵入を防止する必要もある。特に、入力装置１は、電子機器の筐体に組み付けて外部に露出させる必要があるので、入力装置１と筐体の間に、隙間が形成されることは避けられない。また、入力装置１を構成する回転ダイアル３と押ボタン４の間にも、構造上隙間が形成されてしまう。 Note that in electronic devices, there is a risk of liquid such as coffee depending on the usage environment, and if this liquid enters the interior through the gaps between the component parts, it may cause malfunction or possibly failure. For this reason, this intrusion must be accurately prevented. For the same reason, it is necessary to prevent the entry of dust in the air into the interior. In particular, since the input device 1 needs to be assembled to the housing of the electronic device and exposed to the outside, it is inevitable that a gap is formed between the input device 1 and the housing. Further, a structural gap is also formed between the rotary dial 3 and the push button 4 constituting the input device 1.

前記入力装置１によれば、入力装置１の回転ダイアル３には外側貯留部２１が形成され、外周壁３ａの上端が筐体の内面に圧接するように構成されている。したがって、筐体と入力装置１の隙間から液体等が侵入したとしても、そこには外側貯留部２１が形成され、しかも、外周壁３ａの上端が筐体の内面に圧接しているので、内部空間に至って不具合を発生させることがない。また、入力装置１の回転ダイアル３と押ボタン４の間の隙間から液体等が侵入したとしても、そこには内側貯留部２０が形成され、しかも、内側内周壁１９の上端と押ボタン４の操作部２６の下面の間には弾性シート２８が挟持されているので、内部に至ることはない。 According to the input device 1, the outer storage portion 21 is formed in the rotary dial 3 of the input device 1, and the upper end of the outer peripheral wall 3 a is configured to be in pressure contact with the inner surface of the casing. Therefore, even if liquid or the like enters from the gap between the housing and the input device 1, the outer storage portion 21 is formed there, and the upper end of the outer peripheral wall 3a is in pressure contact with the inner surface of the housing. It does not cause problems when it reaches the space. Even if liquid or the like enters from the gap between the rotary dial 3 and the push button 4 of the input device 1, the inner storage portion 20 is formed there, and the upper end of the inner inner peripheral wall 19 and the push button 4 Since the elastic sheet 28 is sandwiched between the lower surfaces of the operation unit 26, it does not reach the inside.

（他の実施形態）
本発明は、前記実施形態に記載の構成に限定されることなく種々の変更が可能である。 (Other embodiments)
The present invention can be variously modified without being limited to the configuration described in the embodiment.

前記中間部材６に形成した弾性腕部３８は、４箇所としたが、２又は３箇所、あるいは、５箇所以上としてもよい。また、その形態は、内径側から外径側に放射状に延びる片持ち梁構造に限らず、外径側から内径側に延びる片持ち梁構造や周方向に延びる片持ち梁構造、あるいは、これらの組み合わせにより構成することも可能である。また、スイッチ部は４箇所としたが、２又は３箇所、あるいは、５箇所以上としてもよい。この場合、中間部材６に形成した支持用突部４０を除去し、係止部４１を外周縁に設けることにより、プリント基板２の外縁に係止するように構成すれば、弾性腕部３８を形成可能な領域の制約が少なくなり、形状、数量等を自由に設定することが可能となる。 The elastic arm portions 38 formed on the intermediate member 6 are four places, but may be two or three places, or five places or more. The form is not limited to the cantilever structure extending radially from the inner diameter side to the outer diameter side, but the cantilever structure extending from the outer diameter side to the inner diameter side, the cantilever structure extending in the circumferential direction, or these It is also possible to configure by a combination. Moreover, although the switch part was four places, it is good also as two or three places or five places or more. In this case, if the supporting protrusions 40 formed on the intermediate member 6 are removed and the locking portions 41 are provided on the outer peripheral edge so as to be locked to the outer edge of the printed circuit board 2, the elastic arm portions 38 are formed. The restrictions on the area that can be formed are reduced, and the shape, quantity, etc. can be set freely.

前記回転ダイアル３は、内側内周壁１９の内周面を中間部材３の小径部４４で正逆回転可能に支持するようにしたが、図９に示すように、内側内周壁１９をさらに内周側に延設し、その内周面を押ボタン４の軸部２７の外周面で支持するように構成してもよい。 The rotary dial 3 supports the inner peripheral surface of the inner inner peripheral wall 19 by the small diameter portion 44 of the intermediate member 3 so as to be able to rotate forward and backward. However, as shown in FIG. Alternatively, the inner peripheral surface may be supported by the outer peripheral surface of the shaft portion 27 of the push button 4.

前記回転ダイアル３は、単に回転可能に支持するだけの構造としたが、所定角度ずつ回転させることによりクリック感を持たせるように構成してもよい。例えば、プリント基板２側に前記環状マグネット２５と同様な環状マグネットを対向して配置し、異極が対向することにより位置決めされるように構成したり、回転ダイアル３に中間部材６の上方側の突起３９ａが係脱する係合凹部を形成するように構成したりすればよい。 The rotary dial 3 is simply structured to be rotatably supported. However, the rotary dial 3 may be configured to have a click feeling by being rotated by a predetermined angle. For example, an annular magnet similar to the annular magnet 25 is disposed on the printed circuit board 2 side so as to be positioned by facing different poles, or the rotary dial 3 is positioned above the intermediate member 6. What is necessary is just to comprise so that the engagement recessed part which the protrusion 39a engages / disengages may be formed.

前記プリント基板２及びそこに貼着する被覆シート１１は、入力装置１の構成部品の１つとしたが、入力装置１を組み込む電子機器の一部で構成することも可能である。 The printed circuit board 2 and the covering sheet 11 adhered to the printed circuit board 2 are one of the components of the input device 1.

前記回転ダイアル３には環状マグネット２５を一体的に設けるようにしたが、周方向の複数箇所に所定ピッチでマグネットを設けるようにしてもよいし、他の部品、例えば、ロータリエンコーダやポテンショメータ等を使用することも可能である。 The rotary dial 3 is provided with the annular magnet 25 integrally. However, the rotary dial 3 may be provided with magnets at a predetermined pitch at a plurality of locations in the circumferential direction, and other parts such as a rotary encoder and a potentiometer may be provided. It is also possible to use it.
