次に回転式電子部品１の組立方法を説明すると、まず予め回転体３０の摺動子取付面３３に摺動子５０の本体部５１の一方の面（接点部５３が突出する側と反対側の面）を当接し、その際回転体３０に設けた固定部４４を摺動子５０に設けた取付部５６に挿入してその先端を熱カシメすることで固定する。次に回転体３０を、取付部材２０に取り付けたフレキシブル回路基板１０の機能パターン部１１の表面上に設置し、その際フレキシブル回路基板１０及び取付部材２０の貫通孔１７，２７に、回転体３０の一方の回転軸３２を回動自在に挿入する。次に、回転体３０のコイル部設置部３９内にねじりコイルスプリング６０のコイル部６１を設置して、両端の引出部６２をそれぞれ回転体３０の引出部挿通部４１と引出部挿通部４２に挿入し、第１当接部４０ａと第２当接部４２ａに弾接させる。このとき引出部６２の先端は引出部挿通部４２からその外方に突出し、取付部材２０の第２引出部係止部２４ａ，２５ａ上に弾接している。そして、回転体３０の前面（収納部３４を設けた面）に押え部材６５を設置して被せ、押え部材６５の挿入部６６に回転体３０の回転軸３１を挿入して回動自在に軸支し、このとき同時に押え部材６５の各挿入固定部６８に取付部材２０の各固定部２６を挿入してその先端を熱カシメして固定する。これによって回転体３０の回転軸３１，３２はそれぞれ回転体３０の両側において取付部材２０と押え部材６５に軸支される。また押え部材６５を取り付けることで、取付部材２０から回転体３０が外れず、且つ回転体３０の収納部３４からねじりコイルスプリング６０が抜け出ない。このとき摺動子５０の接点部５３は機能パターン部１１の摺接パターン１３上にそれぞれ当接し、これら摺接パターン１３及び摺動子５０の接点部５３が回転体３０の長手方向の両端部の近傍位置に設置された状態になっている。   Next, a method of assembling the rotary electronic component 1 will be described. First, one surface of the main body 51 of the slider 50 (on the side opposite to the side from which the contact portion 53 protrudes) is placed on the slider mounting surface 33 of the rotating body 30 in advance. The fixing portion 44 provided on the rotating body 30 is inserted into the mounting portion 56 provided on the slider 50 and the tip thereof is fixed by heat caulking. Next, the rotating body 30 is installed on the surface of the functional pattern portion 11 of the flexible circuit board 10 attached to the mounting member 20, and the rotating body 30 is inserted into the through holes 17 and 27 of the flexible circuit board 10 and the mounting member 20 at that time. The one rotating shaft 32 is rotatably inserted. Next, the coil part 61 of the torsion coil spring 60 is installed in the coil part installation part 39 of the rotator 30, and the lead-out parts 62 at both ends are respectively connected to the lead-out part insertion part 41 and the lead-out part insertion part 42 of the rotator 30. Inserted and elastically contacted with the first contact part 40a and the second contact part 42a. At this time, the leading end of the leading portion 62 protrudes outward from the leading portion insertion portion 42 and is in elastic contact with the second leading portion locking portions 24 a and 25 a of the mounting member 20. Then, the pressing member 65 is installed and covered on the front surface of the rotating body 30 (the surface on which the storage portion 34 is provided), and the rotating shaft 31 of the rotating body 30 is inserted into the insertion portion 66 of the pressing member 65 so as to be rotatable. At this time, the fixing portions 26 of the mounting member 20 are inserted into the insertion fixing portions 68 of the pressing member 65 at the same time, and their tips are fixed by heat caulking. Thereby, the rotating shafts 31 and 32 of the rotating body 30 are pivotally supported by the mounting member 20 and the pressing member 65 on both sides of the rotating body 30, respectively. Further, by attaching the pressing member 65, the rotating body 30 is not detached from the attaching member 20, and the torsion coil spring 60 does not come out from the storage portion 34 of the rotating body 30. At this time, the contact portion 53 of the slider 50 abuts on the sliding contact pattern 13 of the function pattern portion 11, and the sliding contact pattern 13 and the contact portion 53 of the slider 50 are both end portions in the longitudinal direction of the rotating body 30. It is in a state where it is installed in the vicinity of.

そして、つまみ７０の収納部７２を回転体３０のつまみ設置面３５に被せるようにして該つまみ設置面３５を覆うことで、つまみ設置面３５上につまみ７０を設置する。この際回転体３０の一対の回転軸３１，３２の取付部３８を、つまみ７０に設けた一対の係合部７５に係止することで、つまみ７０を回転体３０と一体に設置する。つまみ７０を回転体３０に取り付ける際、図１に示すつまみ７０のテーパ面７６に取付部３８のテーパ面３８ａが当接してつまみ７０の両取付部７４が広がるように撓みながら両係合部７５が両取付部３８にいわゆるスナップイン係合によって容易に係合する。このとき同時に、図５に示すようにつまみ７０に設けた一対の押圧部７３の先端部７３ａが回転体３０に設けた一対の押圧部当接部３７の当接用凹部３７ａに当接する。   Then, the knob 70 is installed on the knob installation surface 35 by covering the knob installation surface 35 so that the storage portion 72 of the knob 70 covers the knob installation surface 35 of the rotating body 30. At this time, the knob 70 is installed integrally with the rotating body 30 by engaging the attachment portions 38 of the pair of rotating shafts 31 and 32 of the rotating body 30 with the pair of engaging portions 75 provided on the knob 70. When the knob 70 is attached to the rotating body 30, both engaging portions 75 are bent while the taper surface 38 a of the attaching portion 38 abuts against the tapered surface 76 of the knob 70 shown in FIG. Are easily engaged with both attachment portions 38 by so-called snap-in engagement. At the same time, as shown in FIG. 5, the tip portions 73 a of the pair of pressing portions 73 provided on the knob 70 come into contact with the contact recesses 37 a of the pair of pressing portion contact portions 37 provided on the rotating body 30.

次に、取付台９０の弾発手段収納部９３内に弾発手段９５を収納した上で、その上に端子パターン８６を上向きとした第２フレキシブル回路基板８５を載置する。次に取付部材２０に取り付けたフレキシブル回路基板１０の端子パターン部１２を、図２に示すように取付部材２０の圧接接続部２２の下面側に折り曲げて、第２フレキシブル回路基板８５上に載置する。そして圧接接続部２２の上面に固定部材８０の押え部８１を載置し、その際固定部材８０の取付片８２を圧接接続部２２の取付片挿入部２９と端子パターン部１２の係合部１６と第２フレキシブル回路基板８５の係合部８９と取付台９０の係合部９４とに係合し、取付片８２の先端を取付台９０の裏面に折り曲げ、これによって取付部材２０を取付台９０に固定すると同時に、取付台９０上に載置した第２フレキシブル回路基板８５の各端子パターン８６とフレキシブル回路基板１０の各端子パターン１４とを圧接接続部２２の下面と弾発手段９５の弾発部９７ａとによって圧接接続する。   Next, after the elastic means 95 is accommodated in the elastic means accommodating portion 93 of the mounting base 90, the second flexible circuit board 85 with the terminal pattern 86 facing upward is placed thereon. Next, the terminal pattern portion 12 of the flexible circuit board 10 attached to the attachment member 20 is bent on the lower surface side of the pressure contact connection portion 22 of the attachment member 20 as shown in FIG. 2 and placed on the second flexible circuit board 85. To do. Then, the pressing portion 81 of the fixing member 80 is placed on the upper surface of the pressure connection portion 22, and at this time, the attachment piece 82 of the fixing member 80 is attached to the attachment piece insertion portion 29 of the pressure connection portion 22 and the engagement portion 16 of the terminal pattern portion 12. And the engaging portion 89 of the second flexible circuit board 85 and the engaging portion 94 of the mounting base 90, and the tip of the mounting piece 82 is bent to the back surface of the mounting base 90, thereby attaching the mounting member 20 to the mounting base 90. At the same time, the terminal patterns 86 of the second flexible circuit board 85 and the terminal patterns 14 of the flexible circuit board 10 placed on the mounting base 90 are connected to the lower surface of the press-connecting portion 22 and the impact of the impact means 95. A pressure contact is made with the portion 97a.

以上のようにして組み立てられた回転式電子部品１は、図５に示すように、回転体３０の外周側面の上面部に設けたつまみ７０を設置するつまみ設置面３５を平面状に形成している。これにより、従来の回転体の外周形状を円形に形成した場合と比較して、つまみ７０を回転体３０の外周側面上に一体に設置した際の該つまみ７０と回転体３０を合わせた高さ寸法を小さくすることができ、それにより回転式電子部品１の薄型化を図ることができる。またつまみ７０に、回転体３０のつまみ設置面３５を覆って該回転体３０の一部をその内部に収納する収納部７２を備えたので、回転体３０の一部をこの収納部７２内に収納した状態でつまみ７０を回転体３０に一体に設置できるため、その分つまみさらに７０と回転体３０を合わせた高さ寸法の小型化を図ることができる。また回転式電子部品１では、回転体３０をつまみ設置面３５上の回転軸方向に直交する方向を長手方向とする横長形状に形成したので、回転体３０の回転軸３１，３２の上側部分だけでなく下側部分も薄型化でき、その点においてもつまみ７０を回転体３０に一体に設置した際のつまみ７０と回転体３０を合わせた高さ寸法を従来よりも小さくすることを可能としている。   As shown in FIG. 5, the rotary electronic component 1 assembled as described above has a knob installation surface 35 on which a knob 70 provided on the upper surface portion of the outer peripheral side surface of the rotating body 30 is formed in a flat shape. Yes. Thereby, compared with the case where the outer periphery shape of the conventional rotating body is formed in a circular shape, the height of the knob 70 and the rotating body 30 when the knob 70 is integrally installed on the outer peripheral side surface of the rotating body 30. The dimensions can be reduced, and thereby the thickness of the rotary electronic component 1 can be reduced. In addition, since the knob 70 is provided with a storage portion 72 that covers the knob installation surface 35 of the rotary body 30 and stores a part of the rotary body 30 therein, a part of the rotary body 30 is placed in the storage portion 72. Since the knob 70 can be installed integrally with the rotating body 30 in the housed state, the height of the knob 70 and the rotating body 30 can be reduced accordingly. In the rotary electronic component 1, the rotating body 30 is formed in a horizontally long shape with the direction orthogonal to the rotating shaft direction on the knob installation surface 35 as the longitudinal direction, so only the upper portions of the rotating shafts 31 and 32 of the rotating body 30 are formed. In addition, the lower portion can also be made thinner, and in this respect, the height dimension of the knob 70 and the rotating body 30 when the knob 70 is installed integrally with the rotating body 30 can be made smaller than the conventional one. .

また回転式電子部品１では、図１に示すように回転体３０の両面から一対の回転軸３１，３２を突出して一方の回転軸３２を取付部材２０に回動自在に軸支し、且つこれら一対の回転軸３１，３２に設けた取付部３８をそれぞれつまみ７０に設けた一対の係合部７５に係合することでつまみ７０と回転体３０とを一体化している。これによりつまみ７０と回転体３０を２ヶ所で係合して固定するのでその取付強度が強くなるばかりか、固定位置が回転体３０の両面側なので力のバランスが良くなり、これらのことからつまみ７０が回転体３０から外れたり、ぐらついたりする恐れがなくなる。特にこの実施形態においては、回転体３０の両側の２つの回転軸３１，３２がそれぞれ取付部材２０と押え部材６５に軸支されているので、回転体３０の軸支が確実で、ぐらつき等は生じない。   Further, in the rotary electronic component 1, as shown in FIG. 1, a pair of rotating shafts 31, 32 protrude from both surfaces of the rotating body 30, and one rotating shaft 32 is pivotally supported on the mounting member 20. The knob 70 and the rotating body 30 are integrated by engaging the mounting portions 38 provided on the pair of rotating shafts 31 and 32 with the pair of engaging portions 75 provided on the knob 70, respectively. As a result, the knob 70 and the rotating body 30 are engaged and fixed at two locations, so that the mounting strength is not only strong, but also the fixing position is on both sides of the rotating body 30 so that the balance of force is improved. There is no fear that 70 is detached from the rotating body 30 or wobbled. Particularly in this embodiment, the two rotating shafts 31 and 32 on both sides of the rotating body 30 are pivotally supported by the mounting member 20 and the pressing member 65, respectively. Does not occur.

図６は、この回転式電子部品１の動作を説明するための動作説明図である。図６と図５を用いて回転式電子部品１の動作を説明する。まず、図５に示すように回転体３０が中立位置にあるときは、ねじりコイルスプリング６０の両引出部６２は、回転体３０の両第１当接部４０ａと取付部材２０の両第１引出部係止部２８とに弾接している。このとき両引出部６２は、回転体３０の両第２当接部４２ａ及び取付部材２０の両第２引出部係止部２４ａ，２５ａにも弾接している。   FIG. 6 is an operation explanatory diagram for explaining the operation of the rotary electronic component 1. The operation of the rotary electronic component 1 will be described with reference to FIGS. First, as shown in FIG. 5, when the rotating body 30 is in the neutral position, the two extraction portions 62 of the torsion coil spring 60 are both the first abutting portions 40 a of the rotating body 30 and the first extraction portions of the mounting member 20. It is in elastic contact with the part locking part 28. At this time, the two drawer portions 62 are also in elastic contact with both the second contact portions 42 a of the rotating body 30 and both the second drawer portion locking portions 24 a and 25 a of the mounting member 20.

そして例えばつまみ７０の一方の操作部７１を押圧操作すると、つまみ７０の一方の押圧部７３の先端部７３ａが回転体３０の押圧部当接部３７の当接用凹部３７ａを押圧することで、回転体３０及びつまみ７０全体が図６に示す矢印Ａ方向に回転し、摺動子５０の接点部５３がフレキシブル回路基板１０の摺接パターン１３上を摺動してその出力を変化する。その際、ねじりコイルスプリング６０の左側の引出部６２が第１引出部係止部２８で係止されて元の位置に保持される一方、右側の引出部６２が第１当接部４０ａによって押し上げられて図６の状態となる。そしてつまみ７０の回動を解除すれば、ねじりコイルスプリング６０の弾発復帰力によって回転体３０及びつまみ７０は元の図５の状態に自動復帰する。なお、回転体３０の回転角度は回転体３０のストッパ当接面３６ａに取付部材２０のストッパ当接部２３ａが当接することで規制される。なお、上記の第１引出部係止部２８による引出部６２の係止の際、引出部６２は取付部材２０の第２引出部係止部２４ａ（２５ａ）でも補助的に係止される。また、第１当接部４０ａで引出部６２が押し上げられる際に、引出部６２は第２当接部４２ａでも補助的に押し上げられる。   For example, when one of the operation portions 71 of the knob 70 is pressed, the tip portion 73a of the one pressing portion 73 of the knob 70 presses the contact recess 37a of the pressing portion contact portion 37 of the rotating body 30. The entire rotary body 30 and knob 70 rotate in the direction of arrow A shown in FIG. 6, and the contact portion 53 of the slider 50 slides on the sliding contact pattern 13 of the flexible circuit board 10 to change its output. At that time, the left drawing portion 62 of the torsion coil spring 60 is locked by the first drawing portion locking portion 28 and held in the original position, while the right drawing portion 62 is pushed up by the first contact portion 40a. As shown in FIG. When the rotation of the knob 70 is released, the rotating body 30 and the knob 70 are automatically returned to the original state shown in FIG. 5 by the elastic return force of the torsion coil spring 60. The rotation angle of the rotating body 30 is regulated by the stopper contact portion 23a of the mounting member 20 coming into contact with the stopper contact surface 36a of the rotating body 30. In addition, when the drawer part 62 is locked by the first drawer part locking part 28, the drawer part 62 is also supplementarily locked by the second drawer part locking part 24a (25a) of the mounting member 20. Moreover, when the drawer | drawing-out part 62 is pushed up by the 1st contact part 40a, the drawer | drawing-out part 62 is also pushed up by the 2nd contact part 42a auxiliary.

この回転式電子部品１では、摺接パターン１３及び摺動子５０の接点部５３を、回転体３０の長手方向の両端部の近傍位置に設けたことにより、これら摺接パターン１３及び摺動子５０の接点部５３を、回転体３０の回転中心軸からできるだけ遠い位置に配置している。これにより回転体３０の回転角度を小さくしても、接点部５３が摺接パターン１３上を摺接する際の十分な分解能を確保することが可能となる。したがって回転体３０の回転角度を小さくでき、つまみ７０の動作範囲も小さくできるので、その分回転式電子部品１の薄型化、小型化を図ることが可能となる。またこの回転式電子部品１では、コイルスプリング６０を回転体３０に取り付けたことによって、回転体３０を中立位置に自動復帰させる自動復帰機構を簡単な構成で実現している。   In the rotary electronic component 1, the sliding contact pattern 13 and the contact 50 of the slider 50 are provided in the vicinity of both ends in the longitudinal direction of the rotating body 30. The 50 contact portions 53 are arranged as far as possible from the rotation center axis of the rotating body 30. Thereby, even when the rotation angle of the rotating body 30 is reduced, it is possible to ensure sufficient resolution when the contact portion 53 is in sliding contact with the sliding contact pattern 13. Accordingly, the rotation angle of the rotating body 30 can be reduced, and the operating range of the knob 70 can be reduced, so that the rotary electronic component 1 can be reduced in thickness and size accordingly.
