Description

本発明は、内部に設置した検出手段に液体が浸入するのを効果的に防止することができる回転式電子部品の防滴構造に関するものである。   The present invention relates to a drip-proof structure for a rotary electronic component that can effectively prevent liquid from entering a detection means installed inside.

従来、デジタルカメラや携帯通信機器等の各種携帯機器、コンピュータ、自動車用電装部品、各種ＯＡ機器、ゲーム機等を操作するデバイス等として、回転式電子部品が使用されている。そしてこの種の回転式電子部品の中には、内蔵した検出手段に水等の液体が浸入しないよう、防滴構造（完全防水ではないが、ある程度液体の浸入を防ぐ構造）を設けたものがある。そして、より効果的な防滴を図ることができる構造の回転式電子部品が求められていた。   Conventionally, rotary electronic components have been used as devices for operating various portable devices such as digital cameras and portable communication devices, computers, automotive electrical components, various OA devices, game machines, and the like. Some of these types of rotary electronic components are provided with a drip-proof structure (not completely waterproof but a structure that prevents liquid from entering to some extent) so that liquids such as water do not enter the built-in detection means. is there. A rotary electronic component having a structure capable of achieving more effective drip-proofing has been demanded.

一方、従来、回転式電子部品の回転つまみをその回転軸に垂直な方向に向けて押圧して下降させることで押圧スイッチをオンする構造の押釦スイッチ付き回転式電子部品がある（特許文献１，２参照）。しかしながら、この種の押釦スイッチ付き回転式電子部品において、防滴構造を有するものは、従来なかった。   On the other hand, conventionally, there is a rotary electronic component with a pushbutton switch having a structure in which a press switch is turned on by pressing and lowering a rotary knob of the rotary electronic component in a direction perpendicular to the rotation axis (Patent Document 1, Patent Document 1). 2). However, no rotary electronic component with this type of pushbutton switch has a drip-proof structure.

また、上記従来の押釦スイッチ付き回転式電子部品においては、例えば特許文献１，２に示すように、１枚のフレキシブル回路基板の回転式電子部品用のスイッチパターン（又は抵抗体パターン）を設けた部分は回転つまみを取り付けた上下動する側の部材に設置され、一方押圧スイッチに用いる押圧スイッチパターンを設けた部分は静止側の部材に設置されていたので、前記上下動する側の部材が上下動するたびにフレキシブル回路基板は、前記回転式電子部品用のスイッチパターンを設けた部分と、押圧スイッチパターンを設けた部分の間で撓むこととなり、前記撓む部分の回路パターンに接続不良等の問題を生じる恐れがあった。   In the conventional rotary electronic component with a pushbutton switch, for example, as shown in Patent Documents 1 and 2, a switch pattern (or resistor pattern) for the rotary electronic component of one flexible circuit board is provided. The part is installed on the member that moves up and down with the rotary knob, while the part that is provided with the press switch pattern used for the push switch is installed on the member on the stationary side. Each time it moves, the flexible circuit board bends between the portion provided with the switch pattern for the rotary electronic component and the portion provided with the pressing switch pattern, and the circuit pattern of the bent portion is poorly connected. Could cause problems.

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、効果的な防滴を図ることができ、また押釦スイッチ付き回転式電子部品に用いて好適な回転式電子部品の防滴構造を提供することにある。   The present invention has been made in view of the above-mentioned points, and the object thereof is to achieve effective drip-proofing, and a drip-proof structure for a rotating electronic component suitable for use in a rotating electronic component with a pushbutton switch. Is to provide.

本発明は、基台と、前記基台の一方の面に設置される回路基板と、前記回路基板上に設置され、軸部を中心に回転する回転体と、前記回路基板と前記回転体との間に設置され、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、前記回転体を覆うカバーと、前記カバーの前記回転体とは反対面側に設置され、前記回転体と一体に回転する回転つまみと、を具備する回転式電子部品において、前記基台及びカバーの対向する面のそれぞれに、前記回路基板を囲む壁部を互い違いに設けることで第１の防滴構造を形成し、前記カバー及び回転つまみの対向する面のそれぞれに、前記軸部を囲む壁部を互い違いに設けることで第２の防滴構造を形成したことを特徴としている。
第１の防滴構造によって、基台とカバーの間から検出手段に向かう液体の浸入を阻止することができる。同時に、第２の防滴構造によって、回転つまみの軸部を通して検出手段に向かう液体の浸入を阻止することができる。また、対向する面のそれぞれに互い違いに壁部を設けるという簡単な構造で防滴構造を構成できる。 The present invention includes a base, a circuit board installed on one surface of the base, a rotating body that is installed on the circuit board and rotates about a shaft portion, the circuit board, and the rotating body. A detecting means for changing an output signal by rotation of the rotating body, a cover covering the rotating body, and a cover on the opposite side of the rotating body, and integrally with the rotating body In a rotary electronic component comprising a rotating rotary knob, a first drip-proof structure is formed by alternately providing walls surrounding the circuit board on each of the opposing surfaces of the base and the cover. The second drip-proof structure is formed by alternately providing wall portions surrounding the shaft portion on each of the opposing surfaces of the cover and the rotary knob.
By the first drip-proof structure, it is possible to prevent the liquid from entering the detection means from between the base and the cover. At the same time, the second drip-proof structure can prevent liquid from entering the detection means through the shaft portion of the rotary knob. Moreover, a drip-proof structure can be comprised with the simple structure of providing a wall part alternately in each of the opposing surface.

また本発明は、前記第１の防滴構造を構成する何れかの壁部の先端とこれに対向する部材間、又は前記第２の防滴構造を構成する何れかの壁部の先端とこれに対向する部材間の少なくとも何れか一方に、弾性を有する防滴部材を圧接挟持したことを特徴としている。
弾性を有する防滴部材を圧接挟持するので、第１，第２の防滴構造における防滴効果を大きく向上させることができる。 In addition, the present invention provides a front end of any wall portion constituting the first drip-proof structure and a member opposed thereto, or a front end of any wall portion constituting the second drip-proof structure and the same. A drip-proof member having elasticity is press-clamped between at least one of the members facing each other.
Since the drip-proof member having elasticity is pressed and clamped, the drip-proof effect in the first and second drip-proof structures can be greatly improved.

また本発明は、前記軸部は前記基台を貫通しており、前記基台の前記回路基板を設置した反対面側に、前記貫通した軸部を中心として前記回転体と一体に回転する第２の回転つまみを設置し、前記第２の回転つまみと前記基台との間に、第２の回転つまみの回転にクリック感触を付与する動作力付与部を設け、前記第２の回転つまみと前記基台の対向する面のそれぞれに、前記動作力付与部の外周側を囲む壁部を互い違いに設けることで第３の防滴構造を形成することを特徴としている。
第３の防滴構造によって、基台と第２の回転つまみの間から動作力付与部に向かう液体の浸入、さらには軸部が貫通する基台の貫通孔を介して前記検出手段に向かう液体の浸入を阻止することができる。
また、基台の表裏両面を挟むように回転つまみ及び第２の回転つまみを設置したので、基台の一方の面側のみに回転つまみを設置する場合に比べて、回転時の力が基台の一方の側に偏らず、回転つまみ及び第２の回転つまみをスムーズに安定して回転することができる。また基台の回転つまみ側に検出手段を、基台の第２の回転つまみ側に動作力付与部を設置したので、基台の一方の側に検出手段と動作力付与部とを設置する場合に比べて、設置スペースに余裕ができて両者を設置し易くなり、また基台から一方の面側に突出する回転つまみの高さ寸法を低くすることができ、この回転式電子部品を装着する機器内での設置スペースの関係で基台から一方の側に回転つまみを高く突出できないような構造が求められてもこの様な要求に応えることができる。 Further, in the present invention, the shaft portion penetrates the base, and on the opposite side of the base on which the circuit board is installed, the shaft rotates integrally with the rotating body around the penetrating shaft portion. 2 is provided, and an operating force applying unit is provided between the second rotary knob and the base to give a click feeling to the rotation of the second rotary knob. A third drip-proof structure is formed by alternately providing walls surrounding the outer peripheral side of the operating force imparting portion on each of the opposing surfaces of the base.
Due to the third drip-proof structure, liquid enters the operating force application unit from between the base and the second rotary knob, and further passes through the through hole of the base through which the shaft part passes to the detection means. Can be prevented from entering.
In addition, since the rotary knob and the second rotary knob are installed so that both the front and back sides of the base are sandwiched, the force during rotation is greater than when the rotary knob is installed only on one side of the base. The rotary knob and the second rotary knob can be smoothly and stably rotated without being biased toward one side of the. In addition, since the detecting means is installed on the rotary knob side of the base and the operating force applying section is installed on the second rotating knob side of the base, the detecting means and the operating force applying section are installed on one side of the base. Compared with, the installation space can be afforded and both can be easily installed, and the height of the rotary knob protruding from the base to one side can be reduced. Such a requirement can be met even if a structure is required in which the rotary knob cannot protrude from the base to one side because of the installation space in the device.

また本発明は、前記第３の防滴構造を構成する何れかの壁部の先端とこれに対向する部材間に、弾性を有する防滴部材を圧接挟持したことを特徴としている。
弾性を有する防滴部材を圧接挟持するので、第３の防滴構造における防滴効果を大きく向上させることができる。 Further, the present invention is characterized in that an elastic drip-proof member is press-clamped between the tip of any wall portion constituting the third drip-proof structure and a member facing the wall portion.
Since the elastic drip-proof member is pressed and clamped, the drip-proof effect in the third drip-proof structure can be greatly improved.

また本発明は、前記回転式電子部品をその回転軸に垂直な方向に向けて上下動自在に取り付けるケースを具備し、前記回路基板をフレキシブル回路基板で構成し、前記基台の前記回転つまみの外周から下方に突出させた押圧スイッチ形成部の下面側に押圧スイッチを設置し、前記検出手段に用いる回路パターンと前記押圧スイッチに用いる回路パターンを、前記１枚のフレキシブル回路基板上に形成してこのフレキシブル回路基板を前記基台の表面に沿わせて取り付け、一方前記ケースの前記押圧スイッチに対向する位置にスイッチ押圧部を設け、前記ケースに対して前記回転式電子部品を下降させることで前記押圧スイッチが前記スイッチ押圧部によって押圧されてオンすることを特徴としている。
この回転式電子部品によれば、回転つまみ（さらには第２の回転つまみ）の外周面をその回転軸に垂直な方向に向けて押圧することで、ケースに対して回転式電子部品を下降させて押圧スイッチをオンすることができる、いわゆる押釦スイッチ付き回転式電子部品を構成することができ、この押釦スイッチ付き回転式電子部品を上述したような防滴構造とすることができる。
さらに上述のように、回転つまみの他に第２の回転つまみを用いて基台を挟む構造にした場合は、基台の回転つまみ及び第２の回転つまみの間から押圧スイッチ形成部を下方に突出する構造となるので、基台に対してその両側に位置する回転つまみ及び第２の回転つまみを同時に押圧することでバランスよく押圧でき、よりスムーズに基台を下降させることができ、その押圧操作感触をより好適にすることができる。
また、基台に設けた押圧スイッチ形成部の下面に、この基台の表面に沿わせて取り付けたフレキシブル回路基板に設けた押圧スイッチを設置したので、押圧スイッチは基台の上下動と共に移動する。このため基台の上下動に対して、フレキシブル回路基板の検出手段に用いる回路パターン部分と、押圧スイッチに用いる回路パターン部分との間の部分が上下動のたびに撓むことはなく、前記両回路パターン間の回路パターンに接続不良等の問題を生じることがなくなる。 The present invention also includes a case for mounting the rotary electronic component so as to be movable up and down in a direction perpendicular to the rotation axis thereof, the circuit board is formed of a flexible circuit board, and the rotary knob of the base is provided. A pressure switch is installed on the lower surface side of the pressure switch forming portion protruding downward from the outer periphery, and a circuit pattern used for the detecting means and a circuit pattern used for the pressure switch are formed on the one flexible circuit board. The flexible circuit board is attached along the surface of the base, while a switch pressing portion is provided at a position facing the pressing switch of the case, and the rotary electronic component is lowered with respect to the case. The pressing switch is pressed by the switch pressing portion and is turned on.
According to this rotary electronic component, the rotary electronic component is lowered with respect to the case by pressing the outer peripheral surface of the rotary knob (and the second rotary knob) in a direction perpendicular to the rotation axis. Thus, a rotary electronic component with a so-called push button switch that can turn on the press switch can be configured, and the rotary electronic component with the push button switch can have a drip-proof structure as described above.
Further, as described above, in the case where the base is sandwiched by using the second rotary knob in addition to the rotary knob, the pressure switch forming portion is moved downward from between the rotary knob and the second rotary knob of the base. Since it has a protruding structure, it can be pressed in a balanced manner by simultaneously pressing the rotary knob and the second rotary knob located on both sides of the base, and the base can be lowered more smoothly. The operation feeling can be made more suitable.
In addition, since the press switch provided on the flexible circuit board attached along the surface of the base is installed on the lower surface of the press switch forming portion provided on the base, the press switch moves with the vertical movement of the base. . For this reason, the part between the circuit pattern part used for the detecting means of the flexible circuit board and the circuit pattern part used for the push switch does not bend each time the base is moved. Problems such as poor connection in circuit patterns between circuit patterns are eliminated.

本発明によれば、効果的な防滴を図ることができ、さらに押釦スイッチ付き回転式電子部品に用いて好適な回転式電子部品の防滴構造とすることができる。   ADVANTAGE OF THE INVENTION According to this invention, effective drip-proof can be aimed at, and also it can be set as the drip-proof structure of a rotary electronic component suitable for using for a rotary electronic component with a pushbutton switch.

When the rotary knob 30 and the second rotary knob 40 are rotated, the ball 201 elastically contacting the click plate 190 by the coil spring 210 is inserted into and removed from the click engagement portion 191 of the click plate 190. A click feeling is obtained.

一方、一体となっている回転つまみ３０及び第２の回転つまみ４０の外周側面を、その上方からその回転軸に垂直な方向に向けて押圧すれば、回転式電子部品１０全体がケース３００に対して下降し、押圧スイッチ６９が押圧部３０５によって押圧されてスイッチ接点板６５が反転し、スイッチがオンする。前記回転つまみ３０及び第２の回転つまみ４０の外周側面への押圧を解除すれば、前記スイッチ接点板６５の弾性復帰力によってスイッチ接点板６５は元の形状に自動復帰してスイッチはオフし、同時に回転式電子部品１０全体がケース３００に対して上昇して元の位置に自動復帰する。   On the other hand, if the outer peripheral side surfaces of the integrated rotary knob 30 and second rotary knob 40 are pressed toward the direction perpendicular to the rotary axis from above, the entire rotary electronic component 10 is against the case 300. The pressure switch 69 is pressed by the pressing portion 305, the switch contact plate 65 is reversed, and the switch is turned on. If the pressing on the outer peripheral side surfaces of the rotary knob 30 and the second rotary knob 40 is released, the switch contact plate 65 automatically returns to its original shape by the elastic return force of the switch contact plate 65, and the switch is turned off. At the same time, the entire rotary electronic component 10 rises with respect to the case 300 and automatically returns to the original position.

ところで、上記押釦スイッチ付き回転式電子部品１に液体が付着し、回転つまみ３０と基台８０の間及び第２の回転つまみ４０と基台８０の間から内部に液体が浸入する場合があるが、この押釦スイッチ付き回転式電子部品１の場合、下記する第１，第２，第３の防滴機構Ａ１，Ａ２，Ａ３（符号Ａ１，Ａ２，Ａ３は図示せず）を設けているので、摺接パターン６０及び摺動子１２０からなっていて回転体３０の回転によって出力信号を変化する検出手段Ｂ１（符号Ｂ１は図示せず）、及びクリック板１９０、ボール２０１、コイルバネ２１０からなっていて第２の回転つまみ４０の回転にクリック感触を付与する動作力付与部Ｂ２（符号Ｂ２は図示せず）への、液体の浸入、付着を効果的に阻止することができる。以下説明する。なお上述のように、Ａ１，Ａ２，Ａ３，Ｂ１，Ｂ２の符号は、何れの図にも図示していない。   By the way, there is a case where liquid adheres to the rotary electronic component 1 with the push button switch and the liquid enters inside from between the rotary knob 30 and the base 80 and between the second rotary knob 40 and the base 80. In the case of the rotary electronic component 1 with the push button switch, the following first, second and third drip-proof mechanisms A1, A2, A3 (reference numerals A1, A2, A3 are not shown) are provided. The detecting means B1 (symbol B1 is not shown) that includes the sliding contact pattern 60 and the slider 120 and changes the output signal by the rotation of the rotating body 30, the click plate 190, the ball 201, and the coil spring 210. It is possible to effectively prevent liquid from entering and adhering to the operating force applying unit B2 (reference numeral B2 is not shown) that gives a click feeling to the rotation of the second rotary knob 40. This will be described below. As described above, the symbols A1, A2, A3, B1, and B2 are not shown in any of the drawings.

即ち、この押釦スイッチ付き回転式電子部品１においては、基台８０及びカバー１５０の対向する面のそれぞれに、フレキシブル回路基板５０を囲む壁部８９，１５９を互い違いに設けるという簡単な構造で第１の防滴構造Ａ１を形成し、これによって基台８０とカバー１５０の間から検出手段Ｂ１に向かう液体の浸入を阻止することができる。またカバー１５０及び回転つまみ３０の対向する面のそれぞれに、軸部４９を囲む壁部１６３，１６５，３７を互い違いに設けるという簡単な構造で第２の防滴構造Ａ２を形成し、これによって、軸部４９を通して検出手段Ｂ１に向かう液体の浸入を阻止することができる。また第２の回転つまみ４０と基台８０の対向する面のそれぞれに、動作力付与部Ｂ２の外周側を囲む壁部５５，９９を互い違いに設けるという簡単な構造で第３の防滴構造Ａ３を形成し、これによって、基台８０と第２の回転つまみ４０の間から動作力付与部Ｂ２に向かう液体の浸入、さらには軸部４９が貫通する基台８０の貫通孔８７を介して検出手段Ｂ１に向かう液体の浸入を阻止することができる。なお回転つまみ３０と軸部４９の先端面間は、ボルト２３０によって強固に密接しているので、ボルト挿入孔３４から浸入しようとする液体が、検出手段Ｂ１に浸入することはない。   That is, the rotary electronic component 1 with a pushbutton switch has a simple structure in which walls 89 and 159 surrounding the flexible circuit board 50 are alternately provided on the opposing surfaces of the base 80 and the cover 150, respectively. The drip-proof structure A1 is formed, thereby preventing the liquid from entering from the base 80 and the cover 150 toward the detection means B1. Further, the second drip-proof structure A2 is formed with a simple structure in which the wall portions 163, 165, and 37 surrounding the shaft portion 49 are alternately provided on the facing surfaces of the cover 150 and the rotary knob 30, respectively. It is possible to prevent the liquid from entering the detection means B1 through the shaft portion 49. Further, the third drip-proof structure A3 has a simple structure in which walls 55 and 99 surrounding the outer peripheral side of the operating force applying part B2 are alternately provided on the opposing surfaces of the second rotary knob 40 and the base 80, respectively. By this, liquid enters from the space between the base 80 and the second rotary knob 40 toward the operating force applying portion B2, and further is detected through the through hole 87 of the base 80 through which the shaft portion 49 passes. Infiltration of the liquid toward the means B1 can be prevented. Since the rotary knob 30 and the front end surface of the shaft portion 49 are firmly in close contact with each other by the bolt 230, the liquid to enter from the bolt insertion hole 34 does not enter the detection means B1.

さらにこの押釦スイッチ付き回転式電子部品１においては、第１の防滴構造Ａ１を構成する一方の壁部１５９の先端とこれに対向する部材（基台８０の表面）間、及び第２の防滴構造Ａ２を構成する一方の壁部３７の先端とこれに対向する部材（カバー１５０の表面）間、及び第３の防滴構造Ａ３を構成する一方の壁部９９の先端とこれに対向する部材（第２の回転つまみ４０の表面）間に、それぞれ弾性を有する防滴部材１１０，１７０，２２０を圧接挟持したので、第１，第２，第３の防滴構造Ａ１，Ａ２，Ａ３における防滴効果を大きく向上させることができる。特にこれら壁部１５９，３７，９９の先端は、鋭角な防滴部材圧接部１６１，３８，１０１としているので、より防滴効果が大きい。   Furthermore, in this rotary electronic component 1 with a pushbutton switch, the second drip-proof structure is formed between the tip of one wall portion 159 constituting the first drip-proof structure A1 and the member (surface of the base 80) facing the wall portion 159. Between the tip of one wall 37 constituting the droplet structure A2 and a member (surface of the cover 150) facing the wall 37, and the tip of one wall 99 constituting the third drip-proof structure A3 and opposite to this. Since the elastic drip-proof members 110, 170, and 220 are press-clamped between the members (the surface of the second rotary knob 40), the first, second, and third drip-proof structures A1, A2, and A3 The drip-proof effect can be greatly improved. In particular, since the tips of the wall portions 159, 37, 99 are the acute-angle drip-proof member press contact portions 161, 38, 101, the drip-proof effect is greater.

また、押圧スイッチ６９においては、リング状のスペーサ部材７５とその上を覆う防水シート７７によって、防滴が図られている。   In addition, in the push switch 69, drip-proofing is achieved by a ring-shaped spacer member 75 and a waterproof sheet 77 covering the same.

またこの押釦スイッチ付き回転式電子部品１によれば、基台８０の表裏両面を挟むように回転つまみ３０及び第２の回転つまみ４０を設置したので、基台８０の一方の面側のみに回転つまみ３０を設置する場合に比べて、回転時の力が基台８０の一方の側に偏らず、回転つまみ３０及び第２の回転つまみ４０をスムーズに安定して回転することができる。また基台８０の回転つまみ３０側に検出手段Ｂ１を、基台８０の第２の回転つまみ４０側に動作力付与部Ｂ２を設置したので、基台８０の一方の側に検出手段と動作力付与部とを設置する場合に比べて、設置スペースに余裕ができて両者を設置し易くなり、また基台８０から一方の面側に突出する回転つまみ３０の高さ寸法を低くすることができ、この押釦スイッチ付き回転式電子部品１を装着する機器内での設置スペースの関係で基台８０から一方の面側に回転つまみ３０を高く突出できないような構造が求められてもこの様な要求に応えることができる。   Further, according to the rotary electronic component 1 with the push button switch, since the rotary knob 30 and the second rotary knob 40 are installed so as to sandwich both the front and back surfaces of the base 80, the rotary electronic component 1 rotates only on one side of the base 80. Compared with the case where the knob 30 is installed, the rotating force is not biased to one side of the base 80, and the rotating knob 30 and the second rotating knob 40 can be smoothly and stably rotated. Further, since the detecting means B1 is installed on the rotary knob 30 side of the base 80 and the operating force applying part B2 is installed on the second rotary knob 40 side of the base 80, the detecting means and the operating force are installed on one side of the base 80. Compared with the case where the attaching portion is installed, the installation space can be afforded and both can be easily installed, and the height of the rotary knob 30 protruding from the base 80 to one surface side can be reduced. Even if a structure is required to prevent the rotary knob 30 from projecting high from the base 80 to one side due to the installation space in the device to which the rotary electronic component 1 with the push button switch is mounted, such a requirement is required. Can respond.

またこの押釦スイッチ付き回転式電子部品１によれば、回転つまみ３０（及び第２の回転つまみ４０）の回転軸に垂直な方向に向けて上下動自在に取り付けるケース３００を具備し、また回路基板をフレキシブル回路基板５０で構成し、基台８０の回転つまみ３０（及び第２の回転つまみ４０）の外周から下方に突出させた押圧スイッチ形成部８５の先端面側（下面側）に押圧スイッチ６９を設置し、検出手段Ｂ１に用いる回路パターンと押圧スイッチ６９に用いる回路パターンを、１枚のフレキシブル回路基板５０上に形成してこのフレキシブル回路基板５０を基台８０の表面に沿わせて取り付け、一方ケース３００の押圧スイッチ６９に対向する位置にスイッチ押圧部３０５を設け、ケース３００に対して回転式電子部品１０を下降させることで押圧スイッチ６９がスイッチ押圧部３０５によって押圧されてオンする構成としたので、回転つまみ３０（さらには第２の回転つまみ４０）の外周面をその回転軸に垂直な方向に向けて押圧することで、ケース３００に対して回転式電子部品１０を下降させて押圧スイッチ６９をオンすることができる、いわゆる押釦スイッチ付き回転式電子部品１を構成することができ、この押釦スイッチ付き回転式電子部品１を上述したような防滴構造とすることができる。   Further, according to the rotary electronic component 1 with the push button switch, the case 300 is provided that can be moved up and down in the direction perpendicular to the rotation axis of the rotary knob 30 (and the second rotary knob 40), and the circuit board. Is formed of the flexible circuit board 50, and the pressure switch 69 is formed on the distal end surface side (lower surface side) of the pressure switch forming portion 85 that protrudes downward from the outer periphery of the rotation knob 30 (and the second rotation knob 40) of the base 80. The circuit pattern used for the detecting means B1 and the circuit pattern used for the pressing switch 69 are formed on one flexible circuit board 50, and the flexible circuit board 50 is attached along the surface of the base 80, On the other hand, a switch pressing portion 305 is provided at a position facing the pressing switch 69 of the case 300, and the rotary electronic component 10 is lowered with respect to the case 300. Thus, since the pressing switch 69 is pressed and turned on by the switch pressing unit 305, the outer peripheral surface of the rotary knob 30 (and also the second rotary knob 40) is pressed in a direction perpendicular to the rotation axis. Thus, the rotary electronic component 1 with a so-called pushbutton switch that can turn on the push switch 69 by lowering the rotary electronic component 10 with respect to the case 300 can be configured. The component 1 can have a drip-proof structure as described above.

さらに上述のように、回転つまみ３０の他に第２の回転つまみ４０を用いて基台８０を挟む構造にした場合は、基台８０の回転つまみ３０及び第２の回転つまみ４０の間から押圧スイッチ形成部８５を下方に突出する構造となるので、基台８０に対してその両側に位置する回転つまみ３０及び第２の回転つまみ４０を同時に押圧することでバランスよく押圧でき、よりスムーズに基台８０を下降させることができ、その押圧操作感触をより好適にすることができる。   Further, as described above, when the base 80 is sandwiched by using the second rotary knob 40 in addition to the rotary knob 30, it is pressed between the rotary knob 30 and the second rotary knob 40 of the base 80. Since the switch forming portion 85 protrudes downward, the rotary knob 30 and the second rotary knob 40 located on both sides of the base 80 can be pressed at the same time so that the switch can be pressed in a balanced manner. The base 80 can be lowered, and the pressing operation feeling can be made more suitable.

また、基台８０に設けた押圧スイッチ形成部８５の先端面（下面）に、この基台８０の表面に沿わせて取り付けたフレキシブル回路基板５０に設けた押圧スイッチ６９を設置したので、押圧スイッチ６９は基台８０の上下動と共に移動する。このため基台８０の上下動に対して、フレキシブル回路基板５０の検出手段Ｂ１に用いる回路パターン部分と、押圧スイッチ６９に用いる回路パターン部分との間の部分が上下動のたびに撓むことはなく、両回路パターン間の回路パターンに接続不良等の問題を生じることがなくなる。   Further, since the pressure switch 69 provided on the flexible circuit board 50 attached along the surface of the base 80 is installed on the front end surface (lower surface) of the pressure switch forming portion 85 provided on the base 80, the pressure switch 69 moves with the vertical movement of the base 80. Therefore, with respect to the vertical movement of the base 80, the portion between the circuit pattern portion used for the detecting means B1 of the flexible circuit board 50 and the circuit pattern portion used for the pressing switch 69 is bent whenever it moves up and down. As a result, problems such as poor connection occur in the circuit pattern between the two circuit patterns.
