The sliding contact pattern 41 may be formed by applying a conductive paint, may be formed by etching the attached metal foil, or may be formed by means such as vapor deposition.

第２回路基板部３３はその外形が前記支持部材基部１１の外形とほぼ同一寸法の略八角形状に形成され、その上面の中央に中央スイッチ４３を設置し、中央スイッチ４３の周囲を囲む位置に等間隔（９０°間隔）に複数（４つ）の押圧スイッチ４５を設置して構成されている。中央スイッチ４３及び押圧スイッチ４５は、何れも第２回路基板部３３上に形成した図示しないスイッチパターン上に弾性金属板をドーム形状に形成してなる反転板（この実施形態では可動接点板）４３ａ，４５ａを設置して構成されている。第２回路基板部３３の上面には第２回路基板部３３とほぼ同一形状で下面に接着層を有する片面接着シートからなる第１防滴シート４７が貼り付けられ、第２回路基板部３３の下面には第２回路基板部３３とほぼ同一形状で上下面に接着層を有する両面接着シートからなる接着シート４９の上面が貼り付けられている。 The outer shape of the second circuit board portion 33 is formed in a substantially octagonal shape having substantially the same dimensions as the outer shape of the support member base portion 11.

The second drip-proof sheet 51 is for drip-proofing and protecting the circuit pattern formed on the connecting portion 35 (the lower surface in FIG. 6). That is, the sliding contact pattern 41 formed on the first circuit board portion 31 and the switch pattern formed on the second circuit board portion 33 are opposite to each other. In this example, the first circuit board portion 31 of FIG. A circuit pattern drawn to the connecting portion 35 from the sliding contact pattern 41 formed on the lower surface side passes through the lower surface side of the connecting portion 35 and is located in the vicinity of the portion connecting the connecting portion 35 of the second circuit board portion 33. The lead-out portion is pulled out by the through hole to the upper surface side of the second circuit board portion 33 and the surface side of the second circuit board portion 33 is connected to the switch pattern constituting the central switch 43 and the push switch 45 together with the circuit pattern. 36. Various circuit patterns on the second circuit board portion 33 are drip-proof by the first drip-proof sheet 47, but the circuit patterns exposed to the connecting portion 35 (lower surface) not drip-proof by the first drip-proof sheet 47 are prevented. A second drip-proof sheet 51 is attached for dripping. Since the adhesive sheet 49 is composed of a double-sided adhesive sheet for adhering to the support member 10, it cannot be used to protect the connecting portion 35 (because the adhesive layer is exposed to the outside). On the other hand, the sliding contact pattern 41 on the first circuit board portion 31 (lower surface) is drip-proof by first and second drip-proof members 350 and 300 described below.

取付台６０は合成樹脂を略円板形状に成形して構成されており、その中央に上方向に向かって突出する筒状突出部６１を設け、その中央に略円形で上下に貫通する開口部６２を設けている。開口部６２は下記する押釦つまみ１８０の押圧部１８３を上下動自在に挿通させるものであり、その内周面には、押釦つまみ１８０の回り止め係合部１８７を係合する軸方向（上下方向）に伸びる溝（上部はスリット）からなる回り止め６３が形成されている。また取付台６０の外周近傍部分の４箇所（下記するケース１５０の各取付台固定部１５７に対向する位置）には、上下に貫通する小孔からなる取付固定部６５が設けられ、また取付台６０の外周から半径方向外方に向かって等間隔に複数（４箇所）の舌片状の係合片６７を突設している。各係合片６７の左右両側辺には小突起状の係止部６９が形成されている。取付台６０の下面の各取付固定部６５の間の所定位置（前記各押圧スイッチ４５に対向する位置）には下方向に向かって柱状に突出する押圧部７１が形成されている。 The mounting base 60 is formed by molding a synthetic resin into a substantially disc shape, and is provided with a cylindrical projecting portion 61 projecting upward in the center thereof, and an opening portion penetrating up and down in a substantially circular shape in the center. 62 is provided.

次にフレキシブル回路基板３０の第１回路基板部３１をその下面（摺接パターン４１を設けた側の面）を上向きとした状態で取付台６０の上面に載置し、その際その開口部３７に取付台６０の筒状突出部６１を挿通する。このとき取付台６０の各取付固定部６５と第１回路基板部３１の各挿通部３９の位置を一致させておく。そしてこの第１回路基板部３１を設置した取付台６０をケース１５０の下側に設置する。このとき回転体９０の開口部９１内に筒状突出部６１を挿入し、同時に押釦つまみ１８０の押圧部１８３をその回り止め係合部１８７を回り止め６３に係合させて開口部６２内に挿通し、押圧部１８３の下端を取付台６０の下面側に突出させる。そしてケース１５０の各取付台固定部１５７を第１回路基板部３１の各挿通部３９と取付台６０の各取付固定部６５とに挿通し、取付台６０の下面側に突出する取付台固定部１５７の先端を熱かしめする。これによって回転体９０に取り付けた摺動子１００の接点部１０７が第１回路基板部３１上の摺接パターン４１に弾接する。またこのとき第２防滴部材３００はケース１５０のつば部１６１の下面と、取付台６０上に載置した第１回路基板部３１の上面とに当接挟持され、若干弾性変形することでケース１５０の側壁部１５３の下端辺と第１回路基板部３１との間の隙間が水密状に密閉される。 Next, the first circuit board portion 31 of the flexible circuit board 30 is placed on the upper surface of the mounting base 60 with its lower surface (the surface on which the sliding contact pattern 41 is provided) facing upward, and in that case, the opening 37 thereof. The cylindrical protrusion 61 of the mounting base 60 is inserted through the base. At this time, the positions of the mounting fixing portions 65 of the mounting base 60 and the insertion portions 39 of the first circuit board portion 31 are matched. Then, the mounting base 60 on which the first circuit board portion 31 is installed is installed below the case 150. At this time, the cylindrical protrusion 61 is inserted into the opening 91 of the rotating body 90, and at the same time, the pressing portion 183 of the push button knob 180 is engaged with the anti-rotation engaging portion 187 with the anti-rotation 63 to enter the opening 62. The lower end of the pressing part 183 is protruded to the lower surface side of the mounting base 60 through the insertion. Then, each mounting base fixing portion 157 of the case 150 is inserted into each insertion portion 39 of the first circuit board portion 31 and each mounting fixing portion 65 of the mounting base 60, and the mounting base fixing portion protruding to the lower surface side of the mounting base 60. The tip of 157 is caulked. As a result, the contact portion 107 of the slider 100 attached to the rotating body 90 comes into elastic contact with the sliding contact pattern 41 on the first circuit board portion 31. At this time, the second drip-proof member 300 is held between the lower surface of the flange portion 161 of the case 150 and the upper surface of the first circuit board portion 31 placed on the mounting base 60, and is slightly elastically deformed to cause the case. A gap between the lower end side of the side wall portion 153 of the 150 and the first circuit board portion 31 is hermetically sealed.

次に前記フレキシブル回路基板３０の連結部３５の部分を下方に折り返すことで、第２回路基板部３３を取付台６０の下面に配置し、さらに第２回路基板部３３の下面側に支持部材１０を設置することで第２回路基板部３３を支持部材１０に貼り付ける。同時に取付台６０の各係合片６７の係止部６９より先端側の部分を支持部材１０の各係合片取付部１３の係合片挿入部１５内にスナップイン係合によって挿入して取り付ける。このとき取付台６０の各押圧部７１はそれぞれ各押圧スイッチ４５の反転板４５ａ上（正確にはその上の第１防滴シート４７上）に当接し、この状態で各係合片６７が各係合片挿入部１５の内周上辺に当接することで、取付台６０が支持部材１０によって揺動自在に支持された状態となる。なおこのとき押釦つまみ１８０の押圧部１８３の下端面も中央スイッチ４３の反転板４３ａ上（正確にはその上の第１防滴シート４７上）に当接し、同時にそのつば部１８５の上面は回転つまみ２１０の本体部２１１の下面（張出し部２２１の下面）に当接または接近している。以上により図１に示す多機能形電子部品１−１が完成する。なお上記組立手順はその一例であり、他の各種異なる組立手順を用いて組み立てても良いことはいうまでもない。なお図１に示す４００は外装ケースであり、その開口部４０１内に回転つまみ２１０が挿入設置される。 Next, the second circuit board portion 33 is disposed on the lower surface of the mounting base 60 by folding back the portion of the connecting portion 35 of the flexible circuit board 30, and the support member 10 is further provided on the lower surface side of the second circuit board portion 33. Is attached to the support member 10. At the same time, a portion of the front end side of the engaging portion 67 of each engaging piece 67 of the mounting base 60 is inserted into the engaging piece inserting portion 15 of each engaging piece attaching portion 13 of the support member 10 by snap-in engagement and attached. . At this time, each pressing portion 71 of the mounting base 60 abuts on the reversing plate 45a of each pressing switch 45 (more precisely, on the first drip-proof sheet 47 above), and in this state, each engaging piece 67 By contacting the upper side of the inner periphery of the engagement piece insertion portion 15, the mounting base 60 is swingably supported by the support member 10. At this time, the lower end surface of the pressing portion 183 of the push button knob 180 is also in contact with the reversing plate 43a of the central switch 43 (more precisely, the first drip-proof sheet 47 thereon), and at the same time, the upper surface of the collar portion 185 is rotated. The knob 210 is in contact with or close to the lower surface of the main body 211 (the lower surface of the overhang portion 221). Thus, the multifunctional electronic component 1-1 shown in FIG. 1 is completed. The above assembling procedure is an example, and it goes without saying that the assembly may be performed using other various assembling procedures. Note that reference numeral 400 shown in FIG. 1 denotes an exterior case, and the rotary knob 210 is inserted and installed in the opening 401 thereof.

次に多機能形電子部品１−１の動作を説明する。まず回転つまみ２１０を回転すると、これと一体にクリックバネ１２０及び回転体９０及び摺動子１００が回転し、これによってクリックバネ１２０の弾接部１３１がケース１５０のクリック係合部１５９に弾接係合してクリック感触が生じると共に、摺動子１００の接点部１０７が第１回路基板部３１の摺接パターン４１上を摺動して摺接パターン４１の電気的出力が変化する。なお回転つまみ２１０を回転した際、これと一体に第１防滴部材３５０も回転するが、押釦つまみ１８０はその回り止め係合部１８７が取付台６０の回り止め６３に係合しているので回転しない。つまり押釦つまみ１８０は第１防滴部材３５０の回転に追従（供回り）しない。このように構成したのは、押釦つまみ１８０の本体部１８１表面に所望の方向性のある表示（例えば矢印や記号など）を施していたような場合にその表示が回転するのを防止するためである。従って前記表示が方向性のないもの（例えば同一色だけを全面（またはリング状や円形など）に形成したもの）の場合は、押釦つまみ１８０が回転つまみ２１０と一体に回転するようにしても良い。つまり前記回り止め係合部１８７と回り止め６３を省略しても良い。 Next, the operation of the multifunctional electronic component 1-1 will be described. First, when the rotary knob 210 is rotated, the click spring 120, the rotating body 90, and the slider 100 are rotated integrally therewith, whereby the elastic contact portion 131 of the click spring 120 is elastically contacted with the click engagement portion 159 of the case 150. A click feeling is produced by the engagement, and the contact portion 107 of the slider 100 slides on the sliding contact pattern 41 of the first circuit board portion 31 so that the electrical output of the sliding contact pattern 41 changes. When the rotary knob 210 is rotated, the first drip-proof member 350 is also rotated integrally therewith, but the push button knob 180 has its anti-rotation engaging portion 187 engaged with the anti-rotation 63 of the mounting base 60. Does not rotate. That is, the push button knob 180 does not follow (turn around) the rotation of the first drip-proof member 350. The reason for this is to prevent the display from rotating when a display having a desired direction (for example, an arrow or a symbol) is provided on the surface of the main body 181 of the pushbutton knob 180. is there. Therefore, when the display has no directionality (for example, only the same color is formed on the entire surface (or a ring shape or a circle)), the push button knob 180 may rotate integrally with the rotary knob 210. . That is, the anti-rotation engagement portion 187 and the anti-rotation 63 may be omitted.

一方押釦つまみ１８０の本体部１８１の上面を押圧すると、押釦つまみ１８０が下降してその押圧部１８３が中央スイッチ４３の反転板４３ａを押圧して反転させ、これによって中央スイッチ４３がオンする。押釦つまみ１８０への押圧を解除すれば、反転板４３ａは元の形状に自動復帰し、押釦つまみ１８０は押し上げられて中央スイッチ４３はオフする。一方回転つまみ２１０の本体部２１１上面の、前記取付台６０の何れかの押圧部７１に対応する部分を下方向に押圧すると、取付台６０上に設置している各構成部品（ケース１５０や回転体９０や回転つまみ２１０など）が取付台６０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７１がこれに対向する押圧スイッチ４５の反転板４５ａを押圧して反転させてその押圧スイッチ４５をオンする。前記回転つまみ２１０への押圧を解除すれば、反転板４５ａの自動復帰力で取付台６０上の回転つまみ２１０を含む各構成部品が一体に元の位置に自動復帰し、押圧スイッチ４５はオフする。 On the other hand, when the upper surface of the main body portion 181 of the push button knob 180 is pressed, the push button knob 180 is lowered and the pressing portion 183 presses and reverses the reverse plate 43a of the central switch 43, whereby the central switch 43 is turned on. When the push on the push button knob 180 is released, the reverse plate 43a automatically returns to its original shape, the push button knob 180 is pushed up, and the central switch 43 is turned off. On the other hand, when a portion of the upper surface of the main body 211 of the rotary knob 210 corresponding to any one of the pressing portions 71 of the mounting base 60 is pressed downward, each component (case 150 or rotation) installed on the mounting base 60 is pressed. The body 90, the rotary knob 210, etc.) are tilted and swung in the direction of being pressed together with the mounting base 60, and the pressing portion 71 on the lowered side presses the reversing plate 45a of the pressing switch 45 opposed thereto to invert it. Then, the push switch 45 is turned on. When the pressure on the rotary knob 210 is released, the components including the rotary knob 210 on the mounting base 60 are automatically returned to their original positions by the automatic return force of the reversing plate 45a, and the pressure switch 45 is turned off. .

この多機能形電子部品１−１を例えば携帯型端末装置などに用いた場合は、一例として回転つまみ２１０の回転操作によって所定の操作内容を順に携帯型端末装置の表示部に表示させ、回転つまみ２１０を揺動させる操作で前記表示させた操作内容の内の何れかを選択し、さらに押釦つまみ１８０を押圧する操作でこの選択した操作内容を確定するなどして用いることができる。 When this multifunctional electronic component 1-1 is used in, for example, a portable terminal device, for example, predetermined operation contents are sequentially displayed on the display unit of the portable terminal device by rotating operation of the rotary knob 210. Any one of the displayed operation contents can be selected by an operation of swinging 210, and the selected operation contents can be confirmed by an operation of pressing the push button knob 180.

以上説明したように多機能形電子部品１−１は、ケース１５０と、ケース１５０の上部に設置されケース１５０に設けた開口１５５内に回転自在に挿入される軸支部２１５及び軸支部２１５中央に設けられる開口部２１２を有する回転つまみ２１０と、ケース１５０の下部に設置され回転つまみ２１０の軸支部２１５に連結される回転体９０と、回転体９０の回転によって電気的出力が変化する摺動子１００及び摺接パターン４１からなる電気的機能部と、ケース１５０及び回転体９０を載置する取付台６０と、回転つまみ２１０に設けた開口部２１２内に上下動自在に設置される押釦つまみ１８０と、取付台６０の下側に設置されて取付台６０を揺動自在に支持する支持部材１０と、支持部材１０上に設置され取付台６０の揺動によって押圧される押圧スイッチ４５と、支持部材１０上に設置され押釦つまみ１８０の下面から突出する押圧部１８３によって押圧される中央スイッチ４３とを具備して構成されている。 As described above, the multi-function electronic component 1-1 is provided at the center of the case 150, the shaft support 215 installed on the upper part of the case 150, and rotatably inserted into the opening 155 provided in the case 150. A rotary knob 210 having an opening 212 provided, a rotary body 90 installed at a lower portion of the case 150 and connected to a shaft support portion 215 of the rotary knob 210, and a slider whose electrical output changes due to the rotation of the rotary body 90. 100 and the sliding contact pattern 41, the mounting base 60 on which the case 150 and the rotating body 90 are placed, and a push button knob 180 that can be moved up and down in an opening 212 provided in the rotary knob 210. And a support member 10 installed below the mounting base 60 to support the mounting base 60 in a swingable manner, and pushed by swinging the mounting base 60 installed on the support member 10. A push switch 45 which is, is configured by including a central switch 43 is pressed by the pressing portion 183 that protrudes from the lower surface of the installed push button knob 180 on the support member 10.

そしてさらに多機能形電子部品１−１は各種防滴機能を具備しており、電気的な動作を行う部分全てが保護されている。即ち多機能形電子部品１−１は、回転つまみ２１０の開口部２１２の部分に軸支部２１５よりも開口部２１２側に張出す張出し部２２１を設け、一方張出し部２２１の下面と回転体９０の上面との間にクリックバネ１２０を介在して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とを有する第１防滴部材３５０を設置しており、この第１防滴部材３５０によって回転つまみ２１０の開口部２１２と押釦つまみ１８０の間の隙間から浸入した液体が回転体９０側（即ち摺動子１００と摺接パターン４１からなる電気的機能部側）に浸入するのを確実に防止している。なお前述のように、覆い板部３５３は筒状の防滴挟持部３５１の内周下部から内側に向かって突出する根本部３５５と、根本部３５５から円錐台形状に上方向に突出する側壁部３５７とを設けているので、防滴挟持部３５１の内側に凹部ａ１が形成され、これによって回転つまみ２１０と押釦つまみ１８０の間の隙間から浸入した液体は通常重力によってこの凹部ａ１に溜り、さらに効果的に電気的機能部側への液体の浸入が防止されている。 Furthermore, the multi-function electronic component 1-1 has various drip-proof functions, and all parts that perform electrical operation are protected. That is, the multi-functional electronic component 1-1 is provided with an overhanging portion 221 that extends to the opening 212 side of the shaft support portion 215 at the opening 212 portion of the rotary knob 210, and the lower surface of the overhanging portion 221 and the rotating body 90 A cylindrical drip-proof sandwiching portion 351 sandwiched between the upper surface and the click spring 120, and a cover plate portion 353 for covering the space inside the drip-proof sandwiching portion 351 and placing the push button knob 180 thereon The first drip-proof member 350 is installed, and the liquid that has entered from the gap between the opening 212 of the rotary knob 210 and the push button knob 180 by the first drip-proof member 350 is on the rotating body 90 side (that is, the slider). 100 and the sliding contact pattern 41 is reliably prevented from entering. As described above, the cover plate portion 353 includes the root portion 355 that protrudes inward from the inner peripheral lower portion of the cylindrical drip-proof sandwiching portion 351, and the side wall portion that protrudes upward from the root portion 355 into a truncated cone shape. 357, a recess a1 is formed inside the drip-proof sandwiching portion 351, so that liquid that has entered from the gap between the rotary knob 210 and the pushbutton knob 180 normally accumulates in the recess a1 due to gravity. The liquid is effectively prevented from entering the electrical functional unit side.

一方回転体９０を囲むケース１５０の側壁部１５３の外周から張出すつば部１６１の下面とつば部１６１の下面に対向する取付台６０（この実施形態の場合はその間に介在する第１回路基板部３１）の上面との間に、ケース１５０の側壁部１５３を取り囲んだ状態で挟持される第２防滴部材３００を設置し、第２防滴部材３００によって外装ケース４００の開口部４０１から浸入した液体がケース１５０と取付台６０（この実施形態の場合はその間に介在する第１回路基板部３１）の間の隙間から回転体９０側（電気的機能部側）に浸入するのを確実に防止している。 On the other hand, the lower surface of the flange portion 161 protruding from the outer periphery of the side wall portion 153 of the case 150 surrounding the rotating body 90 and the mounting base 60 facing the lower surface of the flange portion 161 (in this embodiment, the first circuit board portion interposed therebetween) 31) is installed between the upper surface of the case 150 and the side wall portion 153 of the case 150 so as to surround the second drip-proof member 300, and the second drip-proof member 300 penetrates from the opening 401 of the outer case 400. It is possible to reliably prevent liquid from entering the rotating body 90 side (electrical function portion side) from the gap between the case 150 and the mounting base 60 (in the case of this embodiment, the first circuit board portion 31 interposed therebetween). is doing.

さらに回転つまみ２１０下面とケース１５０上面との間の隙間にはスペーサ部材１７０が挟持されることでその隙間から回転体９０側（電気的機能部側）に液体が浸入するのを確実に防止している。さらに前述のように第２回路基板部３３上の各種回路パターンは第１防滴シート４７によって防滴され、連結部３５上に露出する回路パターンは第２防滴シート５１によって防滴されている。 Further, a spacer member 170 is sandwiched in the gap between the lower surface of the rotary knob 210 and the upper surface of the case 150, so that liquid can be reliably prevented from entering the rotating body 90 side (electrical function portion side) from the gap. ing. Further, as described above, various circuit patterns on the second circuit board portion 33 are drip-proof by the first drip-proof sheet 47, and circuit patterns exposed on the connecting portion 35 are drip-proof by the second drip-proof sheet 51. .

図１０は本発明を用いて構成した第２実施形態にかかる多機能形電子部品１−２の概略断面図である。なお図１０に示す断面図は図示の都合上、図１と同様に各部の断面の位置が異なっている。同図に示す多機能形電子部品１−２において、前記図１〜図９に示す多機能形電子部品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９に示す実施形態と同じである。 FIG. 10 is a schematic cross-sectional view of a multifunctional electronic component 1-2 according to the second embodiment configured using the present invention. Note that, for the sake of illustration, the cross-sectional view shown in FIG. In the multi-function electronic component 1-2 shown in the figure, the same or corresponding parts as those in the multi-function electronic component 1-1 shown in FIGS. Items other than those described below are the same as those in the embodiment shown in FIGS.

この多機能形電子部品１−２において前記多機能形電子部品１−１と相違する点は、押釦つまみ１８０−２の構造と、第１防滴部材３５０−２の構造と、前記多機能形電子部品１−１において設けていた押釦つまみ１８０の回り止め係合部１８７と取付台６０の回り止め６３とを省略した点とである。 The multifunctional electronic component 1-2 differs from the multifunctional electronic component 1-1 in that the structure of the push button knob 180-2, the structure of the first drip-proof member 350-2, and the multifunctional type are described. This is that the anti-rotation engaging portion 187 of the push button knob 180 and the anti-rotation 63 of the mounting base 60 provided in the electronic component 1-1 are omitted.

図１１，図１２は押釦つまみ１８０−２と第１防滴部材３５０−２の分解斜視図であり、図１１は上側から見た図、図１２は下側から見た図である。これらの図に示すように押釦つまみ１８０−２は本体部１８１−２と押圧部１８３−２とが２部品に分離されている。本体部１８１−２と押圧部１８３−２は何れも合成樹脂の成形品であり、本体部１８１−２は略円板状に形成され、その外周下部から薄板リング状のつば部１８５−２を突出して構成されている。押圧部１８３−２は薄板（円板）状の防滴部材当接部１８４−２の下面中央から下方向に柱状の押圧部１８３−２を突出して構成されている。 11 and 12 are exploded perspective views of the push button knob 180-2 and the first drip-proof member 350-2. FIG. 11 is a view from above, and FIG. 12 is a view from below. As shown in these drawings, the push button knob 180-2 has a main body portion 181-2 and a pressing portion 183-2 separated into two parts. Each of the main body portion 181-2 and the pressing portion 183-2 is a molded product of a synthetic resin, and the main body portion 181-2 is formed in a substantially disc shape, and a thin plate ring-shaped collar portion 185-2 is formed from the lower peripheral portion thereof. It is configured to protrude. The pressing portion 183-2 is configured by protruding a columnar pressing portion 183-2 downward from the center of the lower surface of the thin plate (disc) drip-proof member abutting portion 184-2.

一方第１防滴部材３５０−２において前記多機能形電子部品１−１の第１防滴部材３５０と相違する点は、第１防滴部材３５０において設けていた中央の取付孔３６１を省略した点のみである。その他の点は全て前記多機能形電子部品１−１と同一なので、該当部分に同一符号を付し、その説明は省略する。 On the other hand, the first drip-proof member 350-2 is different from the first drip-proof member 350 of the multifunctional electronic component 1-1 in that the central mounting hole 361 provided in the first drip-proof member 350 is omitted. It is only a point. Since all other points are the same as those of the multifunctional electronic component 1-1, the same reference numerals are given to the corresponding portions, and the description thereof is omitted.

そしてこの多機能形電子部品１−２における押釦つまみ１８０−２と第１防滴部材３５０−２の装着手順は、回転つまみ２１０の開口部２１２に本体部１８１−２を挿入し、その下側に第１防滴部材３５０−２を設置し、さらにその下側に押圧部１８３−２を設置することで行なう。それ以外の組み立て手順は前記多機能形電子部品１−１の組み立て手順と同じである。 The procedure for attaching the push button knob 180-2 and the first drip-proof member 350-2 in the multi-function electronic component 1-2 is as follows. The main body 181-2 is inserted into the opening 212 of the rotary knob 210, and the lower side thereof. The first drip-proof member 350-2 is installed, and the pressing portion 183-2 is installed on the lower side thereof. The other assembly procedure is the same as the assembly procedure of the multifunctional electronic component 1-1.

この多機能形電子部品１−２では、図１０に示すように、第１防滴部材３５０−２の覆い板部３５３を本体部１８１−２（その下面）と押圧部１８３−２（防滴部材当接部１８４−２）によって挟持する構造となる。なおこの実施形態では本体部１８１−２（その下面）と押圧部１８３−２（防滴部材当接部１８４−２）とを覆い板部３５３に当接しているだけで接着等していないが、接着等しても良い。そしてこの多機能形電子部品１−２の場合は、前述のように前記多機能形電子部品１−１において設けていた回り止め係合部１８７と回り止め６３とを省略しているので、回転つまみ２１０を回転した際に押釦つまみ１８０もこれと一体に回転する。 In this multi-function electronic component 1-2, as shown in FIG. 10, the cover plate portion 353 of the first drip-proof member 350-2 is replaced with the main body portion 181-2 (the lower surface thereof) and the pressing portion 183-2 (the drip-proof portion). It becomes a structure clamped by the member contact part 184-2). In this embodiment, the main body portion 181-2 (the lower surface thereof) and the pressing portion 183-2 (the drip-proof member abutting portion 184-2) are merely in contact with the cover plate portion 353, but are not bonded to each other. Adhesion or the like may be performed. In the case of the multifunctional electronic component 1-2, the rotation-stop engaging portion 187 and the rotation-stop 63 provided in the multifunctional electronic component 1-1 are omitted as described above. When the knob 210 is rotated, the push button knob 180 also rotates integrally therewith.

そして回転つまみ２１０を回転すると、前記多機能形電子部品１−１の場合と同様にして摺接パターン４１の電気的出力が変化する。一方押釦つまみ１８０−２の本体部１８１−２の上面を押圧すると、本体部１８１−２が当接している覆い板部３５３及び押圧部１８３−２が押圧されて下降し、押圧部１８３−２が中央スイッチ４３の反転板４３ａを押圧して反転させ、これによって中央スイッチ４３がオンする。本体部１８１−２への押圧を解除すれば、反転板４３ａは元の形状に自動復帰し、押圧部１８３−２及び本体部１８１−２は押し上げられて中央スイッチ４３はオフする。一方回転つまみ２１０の本体部２１１上面の、前記取付台６０の何れかの押圧部７１に対応する部分を下方向に押圧すると、前記多機能形電子部品１−１の場合と同様にして下降した側の押圧部７１がこれに対向する押圧スイッチ４５をオンする。前記回転つまみ２１０への押圧を解除すれば押圧スイッチ４５はオフする。 When the rotary knob 210 is rotated, the electrical output of the sliding contact pattern 41 changes in the same manner as in the case of the multifunctional electronic component 1-1. On the other hand, when the upper surface of the main body portion 181-2 of the push button knob 180-2 is pressed, the cover plate portion 353 and the pressing portion 183-2 with which the main body portion 181-2 is in contact are pressed and lowered, and the pressing portion 183-2. Presses the reverse plate 43a of the central switch 43 to reverse it, and the central switch 43 is turned on. When the pressing to the main body portion 181-2 is released, the reversing plate 43a automatically returns to its original shape, the pressing portion 183-2 and the main body portion 181-2 are pushed up, and the central switch 43 is turned off. On the other hand, when a portion corresponding to any pressing portion 71 of the mounting base 60 on the upper surface of the main body 211 of the rotary knob 210 is pressed downward, it is lowered in the same manner as in the case of the multifunctional electronic component 1-1. The pressing part 71 on the side turns on the pressing switch 45 facing this. When the pressure on the rotary knob 210 is released, the pressure switch 45 is turned off.
