Further, the multifunctional electronic component 1 is provided on a swing knob 30 that is an operation knob installed at a position surrounding the rotary knob 20 and a flexible circuit board 70 that is pressed by the swing of the swing knob 30. The outer peripheral switch 78 which is an electrical function part is provided.

次にこの多機能型電子部品１の動作を説明する。まず、回転つまみ２０の操作部２３を指などで操作して回転させることで、板ばね３５及び摺動型物６０が回転つまみ２０と一体に回転する。これにより板ばね３５のクリック弾接部３９がケース４０のクリック係合部４７に弾接係合してクリック感覚が生じると共に、摺動型物６０に取り付けた摺動子６６の摺動接点６７が摺接パターン７５上を摺接し、摺接パターン７５の電気的出力が変化する。この際、３組の摺動接点（図２参照）６７のうちの何れかの組の摺動接点６７の外側の摺接ブラシ６７ａが常にコモンパターン７６（図３参照）に摺接する一方、内側の摺接ブラシ６７ｂ，６７ｃが接点パターン７７ａ，７７ｂ（図３参照）に摺接してこれをオンオフするが、上記したように両接点パターン７７ａ，７７ｂの櫛歯状部は１２０°の間隔よりも若干ずれた位置に設けられているので、いずれかの摺動接点６７が何れか一方の接点パターン７７ａ又は７７ｂに摺接してこれをオンするタイミングと、他の摺動接点６７が他方の接点パターン７７ｂ又は７７ａに摺接してこれをオンするタイミングの位相が少しずれるので、両接点パターン７７ａ，７７ｂから出力されるオンオフ信号の位相が若干ずれるようになっている。これにより、例えば摺動子６６が左右いずれの向きに回転しているかを検出できるようになっている。 Next, the operation of the multifunctional electronic component 1 will be described. First, the leaf spring 35 and the sliding mold 60 are rotated together with the rotary knob 20 by rotating the operating portion 23 of the rotary knob 20 with a finger or the like. As a result, the click elastic contact portion 39 of the leaf spring 35 is elastically engaged with the click engagement portion 47 of the case 40 to produce a click feeling, and the sliding contact 67 of the slider 66 attached to the sliding mold 60 is obtained. Slidably contacts on the sliding contact pattern 75, and the electrical output of the sliding contact pattern 75 changes. At this time, the sliding brush 67a outside the sliding contact 67 of any one of the three sets of sliding contacts (see FIG. 2) 67 is always in sliding contact with the common pattern 76 (see FIG. 3). The sliding brushes 67b and 67c are in sliding contact with the contact patterns 77a and 77b (see FIG. 3) to turn them on and off. As described above, the comb-like portions of the contact patterns 77a and 77b are larger than the interval of 120 °. Since it is provided at a slightly deviated position, the timing at which one of the sliding contacts 67 slides on one of the contact patterns 77a or 77b and turns it on, and the other sliding contact 67 is the other contact pattern. Since the phase of the timing of turning on the slidable contact with 77b or 77a is slightly shifted, the phase of the on / off signal output from both contact patterns 77a and 77b is slightly shifted. Thereby, for example, it is possible to detect whether the slider 66 is rotating in the left or right direction.

一方、押釦つまみ１０の操作部１３を押圧操作することで、押釦つまみ１０が下降してその押圧部１２が中央スイッチ８０の反転板８０ｂを押圧して反転させ、中央スイッチ８０がオンする。押釦つまみ１０への押圧を解除すれば、反転板８０ｂの復帰力で中央スイッチ８０がオフする。また一方で、揺動つまみ３０のいずれかの操作部３２（図３参照）を押圧操作すれば、揺動つまみ３０が揺動してその押圧された操作部３２を設けた位置が下降し、その下面側に設けた押圧部３３が対向する外周スイッチ７８の反転板７８ｂを押圧して反転させて、外周スイッチ７８をオンする。揺動つまみ３０を揺動させている力を解除すれば、連結部材５０と反転板７８ｂの復帰力で揺動つまみ３０は元の位置に自動復帰して、外周スイッチ７８がオフする。 On the other hand, when the operation unit 13 of the push button knob 10 is pressed, the push button knob 10 is lowered and the pressing unit 12 presses the reverse plate 80b of the central switch 80 to reverse it, and the central switch 80 is turned on. If the push on the push button knob 10 is released, the central switch 80 is turned off by the restoring force of the reversing plate 80b. On the other hand, if one of the operation portions 32 (see FIG. 3) of the swing knob 30 is pressed, the swing knob 30 swings and the position where the pressed operation portion 32 is provided is lowered. The reversing plate 78b of the outer peripheral switch 78 opposed to the pressing portion 33 provided on the lower surface side is pressed and reversed, and the outer peripheral switch 78 is turned on. When the force that swings the swing knob 30 is released, the swing knob 30 is automatically returned to the original position by the restoring force of the connecting member 50 and the reverse plate 78b, and the outer peripheral switch 78 is turned off.

この多機能型電子部品１は、携帯型端末装置等に設置して用いる場合には、一例として回転つまみ２０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、揺動つまみ３０を揺動させる操作でこの表示させた操作内容のうちのいずれかを選択し、さらに押釦つまみ１０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 the multifunctional electronic component 1 is installed and used in a portable terminal device or the like, as an example, a predetermined operation content is sequentially displayed on the display unit of the portable terminal device by a rotating operation of the rotary knob 20. Any one of the displayed operation contents can be selected by an operation of swinging the moving knob 30, and the selected operation contents can be confirmed by an operation of pressing the push button knob 10.

上記構成の多機能型電子部品１は、フレキシブル回路基板７０の本体部７１から外方に引き出される連結アーム７２の先方に設けたスイッチ形成用基板部７３に中央スイッチ８０を設置し、連結アーム７２を折り返すことで、中央スイッチ８０をフレキシブル回路基板７０の下面側の押釦つまみ１０の押圧部１２に対向する位置に配置しているので、電気的機能部５５の内側に中央スイッチ８０を配置する必要がなくなり、その分、電気的機能部５５の外径寸法を小型化できるため、多機能型電子部品１の外形寸法の小型化を図ることができる。また、中央スイッチ８０を電気的機能部５５の内側に配置していなくても、電気的機能部５５を構成する摺接パターン７５と中央スイッチ８０を構成する接点パターン８０ａを同一のフレキシブル回路基板７０上に設けることができるので、多機能型電子部品１の部品点数を少なくすることができる。 In the multi-function electronic component 1 having the above-described configuration, the central switch 80 is installed on the switch forming substrate portion 73 provided at the front of the connecting arm 72 drawn outward from the main body portion 71 of the flexible circuit board 70. Since the central switch 80 is disposed at a position facing the pressing portion 12 of the push button knob 10 on the lower surface side of the flexible circuit board 70, it is necessary to dispose the central switch 80 inside the electrical function portion 55. Accordingly, the outer diameter dimension of the electrical functional portion 55 can be reduced accordingly, so that the outer dimension of the multifunctional electronic component 1 can be reduced. Even if the central switch 80 is not disposed inside the electrical functional unit 55, the sliding contact pattern 75 constituting the electrical functional unit 55 and the contact pattern 80a constituting the central switch 80 are the same flexible circuit board 70. Since it can be provided above, the number of components of the multifunctional electronic component 1 can be reduced.

また、スイッチ形成用基板部７３を取付部材９０の下面側に設けた凹部９３内に収納配置したことで、スイッチ形成用基板部７３や中央スイッチ８０が取付部材９０の下面側に突出しないので、多機能型電子部品１を固定側の他の部材などに取り付ける際におけるスイッチ形成用基板部７３や中央スイッチ８０の破損を防止することができ、さらには、多機能型電子部品１の高さ寸法の小型化を図ることが可能となる。 Further, since the switch forming substrate portion 73 is housed and disposed in the recess 93 provided on the lower surface side of the mounting member 90, the switch forming substrate portion 73 and the central switch 80 do not protrude to the lower surface side of the mounting member 90. It is possible to prevent damage to the switch forming substrate 73 and the central switch 80 when the multifunctional electronic component 1 is attached to another member on the fixed side, and further, the height dimension of the multifunctional electronic component 1 It becomes possible to achieve downsizing.

また、凹部９３内に収納配置したスイッチ形成用基板部７３の下面側に中央スイッチ支持板８５を取り付けていることで、この中央スイッチ支持板８５によってスイッチ形成用基板部７３を固定できる上に、スイッチ形成用基板部７３の下面側が保護されるため、凹部９３の下側からスイッチ形成用基板部７３に他の部材が当接することを防止でき、スイッチ形成用基板部７３や中央スイッチ８０の破損を防ぐことができる。 Further, by attaching the central switch support plate 85 to the lower surface side of the switch forming substrate portion 73 housed in the recess 93, the switch forming substrate portion 73 can be fixed by the central switch support plate 85. Since the lower surface side of the switch forming substrate portion 73 is protected, it is possible to prevent other members from coming into contact with the switch forming substrate portion 73 from the lower side of the recess 93, and the switch forming substrate portion 73 and the central switch 80 are damaged. Can be prevented.
