本発明は、防滴機能を有する回転式電子部品に関するものである。 The present invention relates to a rotary electronic component having a drip-proof function.

車載用ナビゲーションシステム、コンピュータ、各種携帯機器、各種ＯＡ機器、ゲーム機等を操作するデバイスとして、例えば特許文献１の図１に示す多機能型電子部品（１）がある。この多機能型電子部品（１）は、回転式電子部品の回転つまみ（１００）の中央に、押圧式電子部品の押釦つまみ（７０）を設置し、さらに回転つまみ（１００）の上面を押圧して揺動することで操作する揺動式電子部品を具備して構成されている。この多機能型電子部品（１）によれば、回転式電子部品の機能と押圧式電子部品の機能と揺動式電子部品の機能とを兼ね備えた多機能型電子部品をコンパクトに構成できる。同時にこの多機能型電子部品（１）は、回転つまみ（１００）の内側の表示部材（１０）上に指標（１５）を形成しているので、この多機能型電子部品（１）を装着する外装ケース（２００）に指標を形成する必要はなく、実質的に多機能型電子部品（１）の外径の小型化が図れる。 As a device for operating an in-vehicle navigation system, a computer, various portable devices, various OA devices, a game machine, etc., there is a multifunctional electronic component (1) shown in FIG.

しかしながら上記特許文献１に示す構造、即ち回転つまみ（１００）の内側に表示部材（１０）を設置する構造の多機能型電子部品においては、従来好適な防滴機能を備えるものはなかった。 However, none of the multi-functional electronic components having the structure shown in Patent Document 1, that is, the structure in which the display member (10) is installed inside the rotary knob (100) has a suitable drip-proof function.

一方、特許文献２に示す多機能型電子部品（１−１）には、その図１に示すように、回転つまみ（２１０）の張出し部（２２１）の下面と回転体（９０）の上面との間に挟持される筒状の防滴挟持部（３５１）と、防滴挟持部（３５１）の内側の空間を覆って押釦つまみ（１８０）を載置する覆い板部（３５３）とを有する弾性部材からなる第１防滴部材（３５０）を設置し、同時にケース（１５０）と取付台（６０）の間にリング形状の第２防滴部材（３００）を挟持するように設置し、これによってそれぞれ部品の隙間の防滴を図る防滴構造が開示されている。 On the other hand, the multifunctional electronic component (1-1) shown in Patent Document 2 includes, as shown in FIG. 1, the lower surface of the overhang portion (221) of the rotary knob (210) and the upper surface of the rotating body (90). And a drip-proof pinching portion (351) having a cylindrical shape and a cover plate portion (353) for covering the space inside the drip-proof pinching portion (351) and mounting the push button knob (180). The first drip-proof member (350) made of an elastic member is installed, and at the same time, the ring-shaped second drip-proof member (300) is sandwiched between the case (150) and the mounting base (60). Discloses a drip-proof structure for preventing drip in a gap between components.

特許文献２に記載の防滴構造は、単に部品と部品の間に弾性部材（防滴部材）を挟持することで防滴を図る構造であり、しかも第１防滴部材（３５０）を挟持するのは相対的に静止している回転つまみ（２１０）と回転体（９０）の間であり、第２防滴部材（３００）を挟持するのも相対的に静止しているケース（１５０）と取付台（６０）の間である。 The drip-proof structure described in Patent Document 2 is a structure that drip-proofs by simply holding an elastic member (drip-proof member) between components, and also holds the first drip-proof member (350). Is between the relatively stationary rotary knob (210) and the rotating body (90), and the second drip-proof member (300) is also relatively stationary with the case (150). Between the mounts (60).

一方、特許文献１に記載の多機能型電子部品のように、回転つまみ（１００）の内側に表示部材（１０）を設置する構造の多機能型電子部品においては、静止している表示部材（１０）と、回転する回転つまみ（１００）の間の隙間を防滴構造にする必要があるが、前記特許文献２に示す防滴構造と同様に、表示部材（１０）と回転つまみ（１００）の間に弾性部材からなる防滴部材を挟持する構成にすると、回転つまみ（１００）の回転に必要以上の摩擦抵抗が働き、そのスムーズな回転が阻害される恐れがあった。また必ず防滴部材が必要なので、部品点数が増加し、コスト削減が図れなかった。 On the other hand, in the multifunctional electronic component having a structure in which the display member (10) is installed inside the rotary knob (100) as in the multifunctional electronic component described in Patent Document 1, the stationary display member ( 10) and the rotating rotary knob (100) need to have a drip-proof structure. Similar to the drip-proof structure shown in Patent Document 2, the display member (10) and the rotary knob (100) If a drip-proof member made of an elastic member is sandwiched between the two, a frictional resistance more than necessary acts on the rotation of the rotary knob (100), and the smooth rotation may be hindered. In addition, since a drip-proof member is always required, the number of parts increases and cost reduction cannot be achieved.

一方、上記特許文献１に示す従来の多機能型の電子部品は、表示部材（１０）の中央に設けた軸部（３１）を、回転つまみ（１００）の中央に設けた開口（１０３）に挿入して回転つまみ（１００）を軸支しているので、軸部（３１）の外径寸法（即ち開口（１０３）の内径寸法）に対して回転つまみ（１００）の外周寸法が相対的に大きくなると、前記軸部（３１）における回転つまみ（１００）の傾き方向への僅かながたつき（傾き）に対して回転つまみ（１００）の外周近傍部分における傾き方向（上下方向）へのがたつきが大きくなってしまう恐れがあった。また軸部（３１）の外径寸法が小さいと、回転つまみ（１００）の外周近傍部分を上下方向にがたつかせた際に開口（１０３）と軸部（３１）間に強い力が働き、回転つまみ（１００）の軸支に支障（回転トルクが大きくなる等）が生じる恐れもあった。 On the other hand, in the conventional multifunctional electronic component shown in Patent Document 1, the shaft portion (31) provided in the center of the display member (10) is provided in the opening (103) provided in the center of the rotary knob (100). Since the rotary knob (100) is inserted and pivotally supported, the outer peripheral dimension of the rotary knob (100) is relative to the outer diameter dimension of the shaft portion (31) (that is, the inner diameter dimension of the opening (103)). When it becomes larger, a slight backlash (inclination) in the tilt direction of the rotary knob (100) at the shaft portion (31) may cause an inclination direction (vertical direction) in the vicinity of the outer periphery of the rotary knob (100). There was a risk that the tackiness would increase. If the outer diameter of the shaft portion (31) is small, a strong force acts between the opening (103) and the shaft portion (31) when the vicinity of the outer periphery of the rotary knob (100) is rattled up and down. There is also a risk that the shaft support of the rotary knob (100) may be hindered (for example, the rotational torque increases).

本発明は上述の点に鑑みてなされたものでありその目的は、回転する回転体（回転つまみ）の中央に静止している表示部材を配置する構造の回転式電子部品において、前記回転体と表示部材の間の隙間を防滴するのに好適な回転式電子部品を提供することにある。 The present invention has been made in view of the above points, and an object of the present invention is to provide a rotary electronic component having a structure in which a stationary display member is disposed at the center of a rotating rotating body (rotating knob). An object of the present invention is to provide a rotary electronic component suitable for drip-proofing a gap between display members.

本発明は、取付台と、前記取付台上に固定される軸部と、軸部から半径方向外方に張り出す表示部とを有する表示部材と、前記取付台と前記表示部材の表示部の間に回動自在に設置される回転体と、前記回転体の回転によって出力信号を変化する検出手段と、を具備する回転式電子部品において、前記回転体と前記表示部の対向する両面の何れか一方の面に凹部を設け、他方の面に前記凹部に挿入される凸部を設け、これによって回転体と表示部の間の隙間にその外周側から液体が浸入することを防止する防滴機構を構成している。
以上のように、凹凸の組合せで回転体と表示部の間の隙間に防滴機構を構成したので、この隙間にその外側から浸入した液体が内部側（中心方向）に向かって浸入していくのを防止することができる。同時に回転体の回転に対する摩擦抵抗は生じず（又は小さく）、回転体のスムーズな回転が行える。 The present invention relates to a display member having a mounting base, a shaft portion fixed on the mounting base, a display portion projecting radially outward from the shaft portion, and the display portion of the mounting base and the display member. In a rotary electronic component comprising a rotating body that is rotatably disposed between and a detection means that changes an output signal by the rotation of the rotating body, any one of the opposing surfaces of the rotating body and the display unit A drip-proof is provided in which a concave portion is provided on one surface, and a convex portion to be inserted into the concave portion is provided on the other surface, thereby preventing liquid from entering the gap between the rotating body and the display portion from the outer peripheral side. The mechanism is configured.
As described above, since the drip-proof mechanism is configured in the gap between the rotating body and the display unit by the combination of the unevenness, the liquid that has entered from the outside enters the gap toward the inner side (center direction). Can be prevented. At the same time, frictional resistance against the rotation of the rotating body does not occur (or is small), and the rotating body can rotate smoothly.

また本発明は、前記防滴機構を構成する凹部と凸部を、前記回転体を回転自在に軸支する回転係合部として兼用させている。このように防滴機構として用いる凹部と凸部を回転係合部としても利用（兼用）するので、構造の簡素化が図れるばかりか、回転体の軸支の径を、表示部材の中央に設ける軸部の径よりも容易に大きく構成することができる。これによって回転体の傾き方向（上下方向）へのがたつきをより小さくすることができる。また回転体の外周近傍部分を上下方向にがたつかせようとする力が働いた場合でも回転係合部に印加される力は小さくて済み、回転体のスムーズな回転が維持できる。 In the present invention, the concave portion and the convex portion constituting the drip-proof mechanism are also used as a rotational engagement portion that rotatably supports the rotating body. As described above, the concave and convex portions used as the drip-proof mechanism are also used (shared) as the rotation engaging portion, so that not only the structure can be simplified, but also the diameter of the shaft support of the rotating body is provided at the center of the display member. It can be easily configured larger than the diameter of the shaft portion. As a result, rattling in the tilt direction (vertical direction) of the rotating body can be further reduced. Further, even when a force that tries to rattle the vicinity of the outer periphery of the rotating body in the vertical direction is applied, the force applied to the rotation engaging portion is small, and smooth rotation of the rotating body can be maintained.

また本発明は、前記防滴機構を、前記回転体に設けた連続する凹部及び凸部を、前記表示部材の表示部に設けた連続する凸部及び凹部にそれぞれ挿入することで構成している。このように連続する凹部及び凸部を、連続する凸部及び凹部に挿入するので、より確実に防滴作用を発揮させることができる。 Moreover, this invention comprises the said drip-proof mechanism by inserting the continuous recessed part and convex part which were provided in the said rotary body in the continuous convex part and recessed part which were provided in the display part of the said display member, respectively. . Thus, since the continuous recessed part and convex part are inserted in a continuous convex part and recessed part, a drip-proof effect | action can be exhibited more reliably.

また本発明は、前記表示部材の表示部に設けた凹部とこの凹部内に挿入される前記回転体に設けた凸部とによって、前記凹部内に挿入した弾性防水部材を挟持することで防滴機能を高めている。このように弾性防水部材を挟持したので、凹部と凸部による防滴作用をさらに高めることができる。なお弾性防水部材は、凹部と凸部による防滴作用を高める（補助する）ために設置されており、従って強い力で挟持する必要はなく、このため回転体の回転に必要以上の摩擦抵抗が働くことはなく、そのスムーズな回転が維持される。 Further, the present invention provides a drip-proof structure by sandwiching the elastic waterproof member inserted into the concave portion between the concave portion provided in the display portion of the display member and the convex portion provided in the rotating body inserted into the concave portion. The function is enhanced. Since the elastic waterproof member is sandwiched in this way, the drip-proofing action by the concave and convex portions can be further enhanced. The elastic waterproofing member is installed in order to enhance (supplement) the drip-proofing action by the concave and convex portions, and therefore it is not necessary to sandwich the elastic waterproofing member with a strong force. It does not work and its smooth rotation is maintained.

また本発明は、前記回転式電子部品が、前記表示部材の中央に設けた押圧用キートップ収納部内に上下動自在に収納した押圧用キートップによって押圧スイッチを押圧操作する押圧式電子部品部を有する構造であり、前記押圧用キートップが、前記表示部材の押圧用キートップ収納部内に収納される押圧操作部と、前記押圧操作部の下面から突出して前記表示部材を貫通しその下に設置した前記押圧スイッチを押圧するスイッチ押圧部とを具備し、さらに前記押圧用キートップの押圧操作部と前記表示部材の押圧用キートップ収納部の間に第２弾性防水部材を挟持している。これによって押圧用キートップの押圧操作部と押圧用キートップ収納部との間の隙間から浸入した液体が内部側に向かって浸入していくのを防止することができる。 According to the present invention, there is provided a press-type electronic component portion in which the rotary electronic component is operated to press a press switch by a press key top that is housed in a press key top storage portion provided in the center of the display member so as to be movable up and down. The pressing key top includes a pressing operation portion that is housed in the pressing key top housing portion of the display member, and protrudes from a lower surface of the pressing operation portion so as to pass through the display member and to be installed therebelow. A switch pressing portion for pressing the pressing switch, and a second elastic waterproof member is sandwiched between the pressing operation portion of the pressing key top and the pressing key top storage portion of the display member. Accordingly, it is possible to prevent the liquid that has entered from the gap between the pressing operation portion of the pressing key top and the pressing key top storage portion from entering the inside.

本発明によれば、回転する回転体（回転つまみ）の中央に静止している表示部材を配置する構造の回転式電子部品において、回転体のスムーズな回転を維持したまま、回転体と表示部材の間の隙間からの液体の浸入を効果的に防止することができる。 According to the present invention, in a rotary electronic component having a structure in which a stationary display member is arranged in the center of a rotating rotating body (rotating knob), the rotating body and the display member are maintained while maintaining smooth rotation of the rotating body. It is possible to effectively prevent the liquid from entering from the gap between the two.

Turns on. When the pressing to the pressing key top 10 is released, the pressing key top 10 returns to the original position by the elastic return force of the reversing plate, and the pressing switch 145 is turned off. The structure in which the pressing switch 145 is pressed by the pressing key top 10 that is housed in the pressing key top housing part 35 provided in the center of the display member 30 in this manner is referred to as a pressing electronic component part. .

次に回転つまみ８０のつまみ操作部８９の前記各指標３７の何れかに対応する部分（その指標３７の半径方向外側の上面部分）を下方向に向けて押圧すれば、回転つまみ８０や表示部材３０や押圧用キートップ１０など、取付台本体１５１上に設置されている各構成部品全体が取付台本体１５１と一体に押圧された方向に傾いて揺動し、下降した側の押圧部１６７が対向する押圧スイッチ１４７の反転板を押圧して反転し、押圧スイッチ１４７がオンする。取付台本体１５１は、連結部１７１及び取付台保持部１５３が撓むことで傾く。回転つまみ８０への押圧を解除すれば、撓んだ連結部１７１及び取付台保持部１５３の元の形状への弾性復帰力と、反転している反転板の弾性復帰力とによって、回転つまみ８０及び取付台本体１５１などの揺動していた全構成部品が一体に元の位置に自動復帰し、押圧スイッチ１４７はオフする。 Next, if a portion corresponding to any of the indicators 37 of the knob operation portion 89 of the rotary knob 80 (the upper surface portion on the radially outer side of the indicator 37) is pressed downward, the rotary knob 80 or the display member 30 and the key top 10 for pressing, etc., all the components installed on the mounting base body 151 are tilted and swung in the direction of being pressed integrally with the mounting base body 151, and the pressing portion 167 on the lowered side is provided. The reversing plate of the opposing pressure switch 147 is pressed and reversed, and the pressure switch 147 is turned on. The mounting base body 151 is tilted by the bending of the connecting part 171 and the mounting base holding part 153. When the pressure on the rotary knob 80 is released, the rotary knob 80 is restored by the elastic return force to the original shape of the bent connecting portion 171 and the mounting base holding portion 153 and the elastic return force of the inverted reversing plate. In addition, all the swinging components such as the mount main body 151 are automatically returned to the original positions, and the pressing switch 147 is turned off.

そして上記回転式電子部品１−１において、表示部材３０の外周と回転つまみ８０の表示部収納部８１の間の隙間から液体が侵入しても、表示部材３０の凸部３３ａ及び凹部３３ｃと、回転つまみ８０の凹部８７ａ及び凸部８７ｂとが噛み合うことで防滴機構が構成されているので、前記隙間から浸入した液体が内部側（中心方向）に向かって浸入していくことは効果的に防止される。同時に回転つまみ８０の回転に対する摩擦抵抗は生じず（又は小さく）、回転つまみ８０のスムーズな回転が行える。さらにこの回転式電子部品１−１の場合、回転つまみ８０の凸部８７ｂと表示部材３０の凹部３３ｃの間において第１弾性防水部材３００が挟持されているので、凹部３３ｃと凸部８７ｂによる防滴機能を高めることができる。なお第１弾性防水部材３００はスポンジ製であって弱い力で容易に圧縮でき、従って弱い力で挟持するので、回転つまみ８０の回転時に生じる第１弾性防水部材３００との摩擦による回転抵抗は小さく、そのスムーズな回転が維持される。なお、高い防滴機能を求めないのであれば、第１弾性防水部材３００はその設置を省略しても良い。 In the rotary electronic component 1-1, even if liquid enters from the gap between the outer periphery of the display member 30 and the display unit storage portion 81 of the rotary knob 80, the convex portion 33a and the concave portion 33c of the display member 30; Since the drip-proof mechanism is configured by engaging the concave portion 87a and the convex portion 87b of the rotary knob 80, it is effective that the liquid that has entered from the gap enters the inner side (center direction). Is prevented. At the same time, frictional resistance against rotation of the rotary knob 80 does not occur (or is small), and the rotary knob 80 can be smoothly rotated. Further, in the case of the rotary electronic component 1-1, since the first elastic waterproofing member 300 is sandwiched between the convex portion 87b of the rotary knob 80 and the concave portion 33c of the display member 30, the prevention by the concave portion 33c and the convex portion 87b. Drop function can be enhanced. The first elastic waterproofing member 300 is made of sponge and can be easily compressed with a weak force. Therefore, the first elastic waterproofing member 300 is sandwiched with a weak force, so that the rotational resistance due to friction with the first elastic waterproofing member 300 generated when the rotary knob 80 rotates is small. That smooth rotation is maintained. If the high drip-proof function is not required, the first elastic waterproof member 300 may be omitted.

一方押圧用キートップ１０の押圧操作部１１の外周と表示部材３０の押圧用キートップ収納部３５の間の隙間から液体が浸入しても、第２弾性防水部材３５０がその浸入を効果的に防止する。第２弾性防水部材３５０もスポンジ製であって弱い力で容易に圧縮できるので、押圧用キートップ１０を押し下げる際の抵抗にはあまりならず、押圧用キートップ１０のスムーズな動作が維持できる。 On the other hand, even if liquid enters from the gap between the outer periphery of the pressing operation portion 11 of the pressing key top 10 and the pressing key top storage portion 35 of the display member 30, the second elastic waterproofing member 350 effectively prevents the penetration. To prevent. Since the second elastic waterproofing member 350 is also made of sponge and can be easily compressed with a weak force, the resistance when pressing down the pressing key top 10 is not so much, and the smooth operation of the pressing key top 10 can be maintained.

なお上記回転式電子部品１−１では、表示部材３０の凸部３３ａ及び凹部３３ｃと、回転つまみ８０の凹部８７ａ及び凸部８７ｂとを噛み合わせることで防滴機構を構成したが、表示部材３０と回転つまみ８０の何れか一方に凹部を設け、他方に凸部を設け、これらを噛み合わせることで防滴機構を構成しても良い。もちろん凹部と凸部の噛み合わせの数が多いほど防滴機能は向上する。 In the rotary electronic component 1-1, the drip-proof mechanism is configured by engaging the convex portions 33a and the concave portions 33c of the display member 30 with the concave portions 87a and the convex portions 87b of the rotary knob 80. A drip-proof mechanism may be configured by providing a concave portion on one of the rotary knob 80 and a convex portion on the other and engaging them. Of course, the greater the number of meshes between the concave and convex portions, the better the drip-proof function.

ところでこの回転式電子部品１−１においては、回転つまみ８０の回転時の軸支を、表示部材３０の表示部３１の下面に設けた回転係合部９０において行うので、表示部材３０の中央に設ける軸部５１の径よりもその径を容易に大きく構成することができる。これによって回転つまみ８０の傾き方向（上下方向、図１の矢印Ｂ方向）へのがたつきをより小さくすることができる。また回転つまみ８０の外周近傍部分を上下方向（矢印Ｂ方向）にがたつかせようとする力が働いた場合でも回転係合部９０に印加される力は小さくて済み、回転つまみ８０のスムーズな回転が維持できる。つまりこの回転式電子部品１−１においては、防滴機構として用いる凹部８７ａと凸部３３ａを回転係合部９０としても利用（兼用）している。なおこの例では凹部８７ａの外側の内周面と凸部３３ａの外周面とを摺動面として回転係合部９０を構成したが、凸部８７ｂの外周面と凸部３３ａの内周面とを摺動面として回転係合部９０を構成したり、凸部８７ｂの内周面と凸部３３ｂの外周面とを摺動面として回転係合部９０を構成しても良い。 By the way, in this rotary electronic component 1-1, since the axial support at the time of rotation of the rotary knob 80 is performed in the rotation engaging part 90 provided in the lower surface of the display part 31 of the display member 30, it is in the center of the display member 30. The diameter can be easily made larger than the diameter of the shaft 51 to be provided. As a result, the backlash of the rotary knob 80 in the tilt direction (vertical direction, arrow B direction in FIG. 1) can be further reduced. Further, even when a force is exerted to rattle the vicinity of the outer periphery of the rotary knob 80 in the vertical direction (arrow B direction), the force applied to the rotary engagement portion 90 can be small, and the rotary knob 80 can be made smooth. Rotation can be maintained. That is, in the rotary electronic component 1-1, the concave portion 87a and the convex portion 33a used as the drip-proof mechanism are also used (also used) as the rotary engagement portion 90. In this example, the rotation engaging portion 90 is configured with the inner peripheral surface outside the concave portion 87a and the outer peripheral surface of the convex portion 33a as sliding surfaces. However, the outer peripheral surface of the convex portion 87b and the inner peripheral surface of the convex portion 33a The rotational engagement portion 90 may be configured with the sliding surface as the sliding surface, or the rotational engagement portion 90 may be configured with the inner peripheral surface of the convex portion 87b and the outer peripheral surface of the convex portion 33b as the sliding surface.

図８は本発明の第２実施形態に係る回転式電子部品１−２の概略側断面図（図１と同一部分の断面図）である。同図に示す回転式電子部品１−２において、前記図１〜図７に示す回転式電子部品１−１と同一又は相当部分には同一符号を付す。なお以下で説明する事項以外の事項については、前記図１〜図７に示す実施形態と同じである。 FIG. 8 is a schematic sectional side view (sectional view of the same part as FIG. 1) of the rotary electronic component 1-2 according to the second embodiment of the present invention. In the rotary electronic component 1-2 shown in the figure, the same or corresponding parts as those of the rotary electronic component 1-1 shown in FIGS. Note that matters other than those described below are the same as those in the embodiment shown in FIGS.

この回転式電子部品１−２において前記回転式電子部品１−１と相違する点は、第１弾性防水部材３００を省略し、その代りに凸部３３ｂの外周側の下端角部に設けた矩形状に凹むリング状の凹部３３１にＯリングからなる弾性防水部材４００を取り付け、この弾性防水部材４００を凹部３３１と凸部８７ｂとによって挟持している点である。このように構成した場合、回転つまみ８０の回転時の回転トルクは大きくなるが、凹部と凸部の噛み合いだけの場合に比べて防滴効果は増大する。 The difference between the rotary electronic component 1-2 and the rotary electronic component 1-1 is that the first elastic waterproofing member 300 is omitted and, instead, a rectangular provided at the lower end corner on the outer peripheral side of the convex portion 33b. An elastic waterproof member 400 made of an O-ring is attached to a ring-shaped concave portion 331 that is recessed in the shape, and the elastic waterproof member 400 is sandwiched between the concave portion 331 and the convex portion 87b. When configured in this manner, the rotational torque during rotation of the rotary knob 80 is increased, but the drip-proof effect is increased as compared with the case where only the concave portion and the convex portion are engaged.

図９は本発明の第３実施形態に係る回転式電子部品１−３の概略側断面図（図１と同一部分の断面図）である。同図に示す回転式電子部品１−３において、前記図１〜図７に示す回転式電子部品１−１と同一又は相当部分には同一符号を付す。なお以下で説明する事項以外の事項については、前記図１〜図７に示す実施形態と同じである。 FIG. 9 is a schematic sectional side view (sectional view of the same part as FIG. 1) of the rotary electronic component 1-3 according to the third embodiment of the present invention. In the rotary electronic component 1-3 shown in the figure, the same or corresponding parts as those of the rotary electronic component 1-1 shown in FIGS. Note that matters other than those described below are the same as those in the embodiment shown in FIGS.

この回転式電子部品１−３において前記回転式電子部品１−１と相違する点は、第１弾性防水部材３００を省略し、その代りに回転つまみ８０の凹部８７ａの中にグリスＧを溜め、これに表示部材３０の凸部３３ａの先端を浸漬させている点である。このように構成した場合も、凹部と凸部の噛み合いだけの場合に比べて防滴効果を増大させることができる。 The difference between the rotary electronic component 1-3 and the rotary electronic component 1-1 is that the first elastic waterproofing member 300 is omitted, and instead the grease G is accumulated in the recess 87a of the rotary knob 80, This is the point in which the tip of the convex portion 33a of the display member 30 is immersed. Even when configured in this manner, the drip-proof effect can be increased as compared with the case where only the concave portion and the convex portion are engaged.

図１０は本発明の第４実施形態に係る回転式電子部品１−４の概略側断面図（図１と同一部分の断面図）である。同図に示す回転式電子部品１−４において、前記図１〜図７に示す回転式電子部品１−１と同一又は相当部分には同一符号を付す。なお以下で説明する事項以外の事項については、前記図１〜図７に示す実施形態と同じである。 FIG. 10 is a schematic sectional side view (sectional view of the same part as FIG. 1) of the rotary electronic component 1-4 according to the fourth embodiment of the present invention. In the rotary electronic component 1-4 shown in the figure, the same or corresponding parts as those of the rotary electronic component 1-1 shown in FIGS. Note that matters other than those described below are the same as those in the embodiment shown in FIGS.

この回転式電子部品１−４において前記回転式電子部品１−１と相違する点は、第１弾性防水部材３００と第２弾性防水部材３５０の両者を省略し、その代りに回転つまみ８０の凸部８７ｂの長さを長くして表示部材３０の凹部３３ｃの底面近傍に至らせ、これによって凹凸による防滴効果を増大させている点と、表示部材３０の押圧用キートップ収納部３５の底面中央から筒状の凸部３６ａを突出し、一方押圧用キートップ１０の押圧操作部１１の下面の外周近傍部分から筒状であって前記凸部３６ａよりも径の大きい筒状の凸部１２を突出し、凸部３６ａの外側に凸部１２を挿入することで防滴機構を形成している点とである。このように構成した場合、弾性防水部材を全く使用しないので、部品点数が削減できる。なおこの例では凸部８７ｂの内周面と凸部３３ｂの外周面とを摺動面として回転係合部９０を構成している。 The difference between the rotary electronic component 1-4 and the rotary electronic component 1-1 is that both the first elastic waterproof member 300 and the second elastic waterproof member 350 are omitted, and the convexity of the rotary knob 80 is used instead. The length of the portion 87b is increased to reach the vicinity of the bottom surface of the recess 33c of the display member 30, thereby increasing the drip-proof effect due to the unevenness, and the bottom surface of the pressing key top storage portion 35 of the display member 30. A cylindrical convex portion 36a protrudes from the center, while a cylindrical convex portion 12 that is cylindrical from the vicinity of the outer periphery of the lower surface of the pressing operation portion 11 of the pressing key top 10 and has a larger diameter than the convex portion 36a. It protrudes and the drip-proof mechanism is formed by inserting the convex part 12 outside the convex part 36a. When configured in this manner, the elastic waterproof member is not used at all, so the number of parts can be reduced. In this example, the rotation engaging portion 90 is configured with the inner peripheral surface of the convex portion 87b and the outer peripheral surface of the convex portion 33b as sliding surfaces.

以上説明したように、本発明に係る回転式電子部品は、取付台１５０と、取付台１５０上に固定される軸部５１及びこの軸部５１から半径方向外方に張り出す表示部３１とを有する表示部材３０と、取付台１５０と表示部材３０の表示部３１の間に回動自在に設置される回転つまみ８０と、回転つまみ８０の回転によって出力信号を変化する摺動子１１０及び摺接パターン１３７からなる検出手段とを具備する構造であって、さらに回転つまみ８０と表示部３１の対向する両面の何れか一方の面に凹部を設け、他方の面に前記凹部に挿入される凸部を設け、これによって回転つまみ８０と表示部３１の間の隙間に外側から液体が浸入するのを防止する防滴機構を設けている。 As described above, the rotary electronic component according to the present invention includes the mounting base 150, the shaft portion 51 fixed on the mounting base 150, and the display portion 31 projecting radially outward from the shaft portion 51. The display member 30, the rotary knob 80 that is rotatably installed between the mount 150 and the display unit 31 of the display member 30, the slider 110 that changes the output signal by the rotation of the rotary knob 80, and the sliding contact And a convex portion that is provided with a concave portion on one of the opposing surfaces of the rotary knob 80 and the display unit 31 and is inserted into the concave portion on the other surface. Thus, a drip-proof mechanism is provided to prevent liquid from entering the gap between the rotary knob 80 and the display unit 31 from the outside.

このように凹凸の組合せで回転つまみ８０と表示部３１の間の隙間に防滴機構を構成したので、この隙間にその外側から浸入した液体が内部側（中心方向）に向かって浸入していくのを防止することができる。同時に回転つまみ８０の回転に対する摩擦抵抗は生じず（又は小さく）、回転つまみ８０のスムーズな回転が行えるようになる。 As described above, since the drip-proof mechanism is configured in the gap between the rotary knob 80 and the display unit 31 by the combination of projections and depressions, the liquid that has entered from the outside enters the gap toward the inner side (center direction). Can be prevented. At the same time, frictional resistance against rotation of the rotary knob 80 does not occur (or is small), and the rotary knob 80 can be smoothly rotated.

同時に本発明においては、前記防滴機構を構成する凹部と凸部を、回転つまみ８０を回転自在に軸支する回転係合部９０として兼用している。このように防滴機構として用いる凹部と凸部を回転係合部９０として兼用するので、構造の簡素化が図れるばかりか、回転つまみ８０の軸支の径を、表示部材３０の中央に設ける軸部５１の径よりも容易に大きく構成することができる。これによって回転つまみ８０の傾き方向（上下方向）へのがたつきをより小さくすることができる。また回転つまみ８０の外周近傍部分を上下方向にがたつかせようとする力が働いた場合でも回転係合部９０に印加される力は小さくて済み、回転つまみ８０のスムーズな回転が維持できる。 At the same time, in the present invention, the concave portion and the convex portion constituting the drip-proof mechanism are also used as the rotation engagement portion 90 that rotatably supports the rotary knob 80. As described above, since the concave and convex portions used as the drip-proof mechanism are also used as the rotation engaging portion 90, not only the structure can be simplified, but also the shaft support diameter of the rotary knob 80 is provided at the center of the display member 30. The diameter of the portion 51 can be easily increased. As a result, rattling of the rotary knob 80 in the tilt direction (vertical direction) can be further reduced. In addition, even when a force that causes the vicinity of the outer periphery of the rotary knob 80 to bend in the vertical direction is applied, the force applied to the rotary engaging portion 90 can be small, and the smooth rotation of the rotary knob 80 can be maintained.

また本発明に係る防滴機構は、回転つまみ８０に設けた連続する凹部及び凸部を、表示部材３０の表示部３１に設けた連続する凸部及び凹部にそれぞれ挿入することで構成している。このように連続する凹部及び凸部を、連続する凸部及び凹部に挿入するので、より確実に防滴作用を発揮させることができる。 In addition, the drip-proof mechanism according to the present invention is configured by inserting continuous concave portions and convex portions provided on the rotary knob 80 into continuous convex portions and concave portions provided on the display portion 31 of the display member 30, respectively. . Thus, since the continuous recessed part and convex part are inserted in a continuous convex part and recessed part, a drip-proof effect | action can be exhibited more reliably.

また本発明に係る回転式電子部品は、表示部材３０の表示部３１に設けた凹部とこの凹部内に挿入される回転つまみ８０に設けた凸部とによって、前記凹部内に挿入した第１弾性防水部材３００を挟持することで防滴機能を高めるように構成している。このように第１弾性防水部材３００を挟持すれば、凹部と凸部による防滴作用をさらに高めることができる。なお第１弾性防水部材３００は、凹部と凸部による防滴作用を高める（補助する）ために設置されており、従って強い力で挟持する必要はなく、このため回転つまみ８０の回転に必要以上の摩擦抵抗が働くことはなく、そのスムーズな回転が維持される。特にこの第１弾性防水部材３００として防水性を有するスポンジによって構成した場合は柔軟性があり、摩擦抵抗が少なく、好適である。 Further, the rotary electronic component according to the present invention includes a first elastic member inserted into the concave portion by the concave portion provided in the display portion 31 of the display member 30 and the convex portion provided in the rotary knob 80 inserted into the concave portion. The waterproof member 300 is sandwiched so that the drip-proof function is enhanced. Thus, if the 1st elastic waterproofing member 300 is clamped, the drip-proof effect | action by a recessed part and a convex part can further be improved. The first elastic waterproofing member 300 is installed in order to enhance (supplement) the drip-proofing action by the concave and convex portions, and therefore does not need to be clamped with a strong force. This friction resistance does not work, and its smooth rotation is maintained. In particular, when the first elastic waterproofing member 300 is constituted by a waterproof sponge, the first elastic waterproofing member 300 is suitable because of its flexibility and low frictional resistance.

また本発明に係る回転式電子部品は、表示部材３０の中央に設けた押圧用キートップ収納部３５内に上下動自在に収納した押圧用キートップ１０によって押圧スイッチ１４５を押圧操作する押圧式電子部品部を有する構造であり、押圧用キートップ１０は、前記表示部材３０の押圧用キートップ収納部３５内に収納される押圧操作部１１と、押圧操作部１１の下面から突出して表示部材３０を貫通しその下に設置した押圧スイッチ１４５を押圧するスイッチ押圧部１３とを具備し、さらに押圧用キートップ１０の押圧操作部１１と表示部材３０の押圧用キートップ収納部３５の間に第２弾性防水部材３５０を挟持して構成されている。これによって表示部材３０の押圧用キートップ収納部３５と押圧用キートップ１０の間の隙間から浸入した液体が回転式電子部品の内部側に向かって浸入していくのを防止することができる。 Further, the rotary electronic component according to the present invention is a press-type electronic device in which the press switch 145 is pressed by the press key top 10 that is housed in the press key top storage portion 35 provided in the center of the display member 30 so as to be movable up and down. The pressing key top 10 has a structure having a part portion, and the pressing key top 10 projects from the pressing operation portion 11 housed in the pressing key top housing portion 35 of the display member 30 and the lower surface of the pressing operation portion 11. And a switch pressing portion 13 that presses the pressing switch 145 installed thereunder, and further between the pressing operation portion 11 of the pressing key top 10 and the pressing key top storage portion 35 of the display member 30. Two elastic waterproofing members 350 are sandwiched. Accordingly, it is possible to prevent the liquid that has entered from the gap between the pressing key top storage portion 35 and the pressing key top 10 of the display member 30 from entering the inside of the rotary electronic component.

また場合によっては、中央の押圧用キートップ１０と押圧用キートップ１０によって押圧操作される中央スイッチ１４５、すなわち押圧式電子部品部の部分を省略しても良い。同様に場合によっては、支持部材２００と第２回路基板部１３５と取付台保持部１５３及び連結部１７１、すなわち揺動式電子部品の部分を省略しても良い。また上記実施形態では回転つまみ８０のみによって回転体を構成したが、例えば摺動子１１０を取り付ける回転体と、つまみ操作部８９を有するつまみ部分とを別部品で構成しても良いなど、その構造には種々の変更が可能である。また取付台保持部１５３は可撓性のない剛体で構成しても良い。その場合でも連結部１７１に可撓性があれば取付台１５０は揺動可能となる。さらに取付台１５０の連結部１７１を省略し、その代わりに例えば別途可撓性を有するフイルム状部材（合成樹脂フイルム等）を用意し、このフイルム状部材によって取付台本体１５１と取付台保持部１５３間を連結するなどしても良い。 In some cases, the central pressing key top 10 and the central switch 145 that is pressed by the pressing key top 10, that is, the portion of the pressing-type electronic component portion may be omitted. Similarly, in some cases, the support member 200, the second circuit board portion 135, the mounting base holding portion 153, and the connecting portion 171, that is, the swinging electronic component portion may be omitted.

Various modifications are possible. Further, the mounting base holding part 153 may be formed of a rigid body having no flexibility. Even in this case, if the connecting portion 171 is flexible, the mounting base 150 can swing.
