Description

本発明は、スイッチ機構及び多方向揺動型スイッチ機構に関するものである。 The present invention relates to switch mechanisms and multidirectional oscillating switch mechanism.

従来、例えば特許文献１の図１に示す多方向揺動型スイッチ機構は、中央とその周囲に複数のスイッチを設置すると共に、複数のスイッチの内の中央に位置するスイッチ上に揺動且つ上下動する操作部材（操作レバー）を設置し、操作部材の周囲を囲むようにスイッチ作動部材（動作板）を設置し、スイッチ作動部材の下面に設けた複数の押圧部の下側に周囲のスイッチが位置するように構成されていた。そして操作部材を押圧すればスイッチ作動部材は移動せずに操作部材のみが下降してその真下にある中央のスイッチがオンし、一方操作部材を揺動すれば操作部材と一体にスイッチ作動部材も揺動して下降した側のスイッチ作動型物の押圧部の真下に位置する周囲のスイッチがオンする。   Conventionally, for example, the multi-directional swing type switch mechanism shown in FIG. 1 of Patent Document 1 has a plurality of switches installed at the center and the periphery thereof, and swings and moves up and down on the switch located at the center of the plurality of switches. A movable operating member (operating lever) is installed, a switch operating member (operating plate) is installed so as to surround the operating member, and a peripheral switch is provided below the plurality of pressing portions provided on the lower surface of the switch operating member. Was configured to be located. If the operating member is pressed, the switch actuating member does not move and only the operating member is lowered and the central switch just below it is turned on. On the other hand, if the operating member is swung, the switch actuating member is integrated with the operating member. The surrounding switches located directly below the pressing portion of the switch actuating type on the side swung and lowered are turned on.

ところでこのような構造の多方向揺動型スイッチ機構においては、前記操作部材は上下動のみではなく揺動動作も行う必要があるのでこの操作部材を上下動方向のみに移動するように直立した姿勢にガイドしておくことはできず、このため操作部材を何ら操作していない無負荷状態の時にこの操作部材が直立した位置よりも少し傾いた状態で停止してしまう恐れがあった。このため特許文献１の場合は上下方向に弾発するコイルスプリングによって操作部材を直立させるようにしている。しかしながらコイルスプリングを用いると、構造が複雑となって部品点数が増加するばかりか、多方向揺動型スイッチ機構の厚みが厚くなってしまうという問題があった。   By the way, in the multi-directional oscillating switch mechanism having such a structure, the operation member needs to perform not only the vertical movement but also the oscillating movement, so that the operation member moves up and down only in the vertical movement direction. Therefore, there is a possibility that the operation member stops in a state where the operation member is slightly tilted from an upright position in a no-load state where the operation member is not operated at all. For this reason, in the case of Patent Document 1, the operation member is made to stand upright by a coil spring that repels in the vertical direction. However, when a coil spring is used, there is a problem that the structure becomes complicated and the number of parts increases, and the thickness of the multi-directional oscillating switch mechanism increases.

また例えば特許文献２の図１に示す二段押釦スイッチ付き回転式電子部品内に設置した二段押釦スイッチ機構は、スイッチを設けた下側のフレキシブル回路基板上に作動型物を設置すると共に作動型物上にスイッチを設けた上側のフレキシブル回路基板を設置し、さらにその上にキートップを設置して構成されている。そしてキートップを押圧するとこのキートップ下面に設けた押圧部によってまず上側のフレキシブル回路基板のスイッチがオンし、さらにキートップを押圧すると作動型物の下面に設けた押圧部によって下側のフレキシブル回路基板上のスイッチがオンする。しかしながら前記作動型物はその上下動がガイドされていないので、これを上下動する際に容易に傾き、スイッチの動作がスムーズに行えなくなる恐れがあった。一方この作動型物の上下動をガイドするガイド機構を設けると、構造が複雑化し、その小型化も阻害されてしまう。
特開平８−６４０８１号公報 特開２００３−１７８６４８号公報 Further, for example, the two-stage pushbutton switch mechanism installed in the rotary electronic component with the two-stage pushbutton switch shown in FIG. 1 of Patent Document 2 installs an operation type object on the lower flexible circuit board provided with the switch and operates. An upper flexible circuit board provided with a switch is installed on a mold, and a key top is further installed thereon. When the key top is pressed, the switch on the upper flexible circuit board is first turned on by the pressing portion provided on the lower surface of the key top, and when the key top is further pressed, the lower flexible circuit is formed by the pressing portion provided on the lower surface of the actuated object. A switch on the board is turned on. However, since the up-and-down movement of the actuating type is not guided, there is a risk that the up-and-down movement easily tilts and the switch cannot be operated smoothly. On the other hand, providing a guide mechanism for guiding the vertical movement of the actuated object complicates the structure and hinders downsizing.

As shown in the figure, a flexible circuit board 20 has a switch pattern 23 for a switch 21 on the upper surface of a single flexible synthetic resin film (for example, polyethylene terephthalate film [PET film], polyimide film [PI film], etc.). 25, and a movable member mounting portion 31 is connected from the outer periphery via a belt-like connecting portion 30. Further, the connecting portion 30 of the movable member mounting portion 31 is 180 ° opposite to the movable member mounting portion 31. A mounting portion 41 is provided so as to protrude from the side in a band shape. A circuit pattern is formed on the upper surface of the flexible circuit board 20 by printing a conductive paste (screen printing in the present embodiment). As a part of the circuit pattern, a pair of switch patterns 23 and 25 and each switch pattern 23 are formed. , 25 and lead patterns 27, 29 are provided. The switch pattern 23 is formed in a circular dot shape, and the switch pattern 25 is formed in a C shape so as to surround the switch pattern 23. Further, two fixed portions 32 and 38 each having a small rectangular through hole are provided at a predetermined position outside the switch pattern 25. Both the fixing portions 32 and 38 are provided on the opposite side of the switch pattern 25 by 180 °. The movable member attaching portion 31 is circular (substantially the same external dimensions as the operation member 60 described below), and a locking portion 33 formed of a circular small hole is provided at a predetermined plurality of locations (four locations in the present embodiment). Is provided. The attachment portion 41 is in the form of a band, and a fixing portion 35 formed of a small rectangular through hole is provided near the tip.

The switch 21 is formed by contacting the switch pattern 25. The operating member 60 is configured by attaching a synthetic resin pressing portion forming portion 71 to the lower surface of a synthetic resin operating portion forming portion 61. The operation portion forming portion 61 projects a rod-like operation portion 65 from the upper surface of a flat plate-shaped (disk-shaped) base portion 63, and a plurality of locations on the lower surface of the base portion 63 (in the present embodiment, the movable member mounting portion 31). From the four portions corresponding to the respective locking portions 33, there are protruding small protrusion-like engaging portions 67 (in FIG. 1, the tip is crushed by thermal caulking). On the other hand, the pressing portion forming portion 71 is formed in a flat plate shape (disc shape), and is provided with a small protrusion-like pressing portion 73 at the center of the lower surface thereof, and through holes for inserting these at positions facing the respective engaging portions 67. The attachment engaging part 75 which consists of is provided.

そして図２に示すフレキシブル回路基板２０の一対のスイッチパターン２３，２５の上に反転板３７を取り付けることでスイッチ２１を構成しておく。次に前記可動部材取付部３１の両面に操作部６０を構成する操作部形成部６１と操作部６０を構成する押圧部形成部７１を設置し（図２では可動部材取付部３１の上面側に押圧部形成部７１が、可動部材取付部３１の下面側に操作部形成部６１が位置する）、その際操作部形成部６１に設けた係合部６７を、可動部材取付部３１に設けた係止部３３と押圧部形成部７１に設けた取付係合部７５とに挿入し、その先端を熱カシメして固定する。これによって操作部形成部６１と押圧部形成部７１とからなる操作部材６０が形成される。そしてフレキシブル回路基板２０を図１に示すように基台１０上に載置すると共に、操作部材６０を取り付けた可動部材取付部３１を連結部３０の部分を折り曲げることで連結部３０を介してフレキシブル回路基板２０の上面側に配置する。このとき固定部３２と固定部３５の位置を一致させておく。そしてフレキシブル回路基板２０を基台１０上に固定する際に、可動部材取付部３１から突出する取付部４１も合わせてフレキシブル回路基板２０上に固定する。フレキシブル回路基板２０及び取付部４１の固定には前記一致させた貫通孔からなる固定部３２，３５と貫通孔からなる固定部３８中に他の部材からなる部片を配置することでなされる。なおフレキシブル回路基板２０及び取付部４１の固定には必ずしも固定部３２，３５，３８を利用する必要はなく、他の各種固定構造によって固定しても良い。その場合は貫通孔からなる固定部３２，３５，３８は不要になる。即ち図１にはその固定部分を概略的に固定手段８０，８１として示しているが、この固定手段８０，８１としては、例えば合成樹脂で形成された基台１０の上面から突出する小突起を両固定部３２，３５，３８に挿入してその先端を熱カシメして固定する構造でも良く、また操作型物６０の上部を覆うケース（これも静止側部材である）の外周下辺をフレキシブル回路基板２０の上面に当接して固定する方法でも良い。要は少なくともフレキシブル回路基板２０の連結部３０の近傍部分（必ずしも連結部３０の根元部分でなくても良く、その周囲部分であっても良い）と、取付部４１とを所望の固定手段８０，８１によって固定すれば良い。これによって操作部材６０を取り付けた可動部材取付部３１は、１８０°対向する位置にある連結部３０と取付部４１の二ヶ所においてフレキシブル回路基板２０や基台１０等からなる静止側部材に取り付けられたことになる。なお連結部３０と取付部４１による操作部材６０の取り付けは、操作部材６０が可動（この実施形態では上下動）し得るように所定の撓みを連結部３０と取付部４１の両者に持たせた状態での取り付けとしている。   And the switch 21 is comprised by attaching the inversion board 37 on the pair of switch patterns 23 and 25 of the flexible circuit board 20 shown in FIG. Next, an operation part forming part 61 constituting the operation part 60 and a pressing part forming part 71 constituting the operation part 60 are installed on both surfaces of the movable member attachment part 31 (on the upper surface side of the movable member attachment part 31 in FIG. 2). The operating portion forming portion 61 is located on the lower surface side of the movable member attaching portion 31), and the engaging portion 67 provided in the operating portion forming portion 61 at that time is provided in the movable member attaching portion 31. It inserts in the latching | locking part 33 and the attachment engagement part 75 provided in the press part formation part 71, and the front-end | tip is fixed by heat crimping. As a result, the operation member 60 including the operation portion forming portion 61 and the pressing portion forming portion 71 is formed. Then, the flexible circuit board 20 is placed on the base 10 as shown in FIG. 1, and the movable member attachment portion 31 to which the operation member 60 is attached is bent through the connection portion 30 by bending the portion of the connection portion 30. It is arranged on the upper surface side of the circuit board 20. At this time, the positions of the fixing portion 32 and the fixing portion 35 are made to coincide. When the flexible circuit board 20 is fixed on the base 10, the mounting part 41 protruding from the movable member mounting part 31 is also fixed on the flexible circuit board 20. The flexible circuit board 20 and the mounting part 41 are fixed by arranging pieces made of other members in the fixing parts 32 and 35 made of the matched through holes and the fixing part 38 made of the through holes. Note that it is not always necessary to use the fixing portions 32, 35, and 38 for fixing the flexible circuit board 20 and the attachment portion 41, and they may be fixed by other various fixing structures. In that case, the fixing portions 32, 35, and 38 including the through holes are unnecessary. That is, in FIG. 1, the fixing portion is schematically shown as fixing means 80 and 81. As the fixing means 80 and 81, for example, a small protrusion protruding from the upper surface of the base 10 made of synthetic resin is used. A structure may be adopted in which both ends are inserted into the fixing portions 32, 35, and 38 and the tips thereof are caulked and fixed, and the lower outer periphery of the case (which is also a stationary member) covering the upper portion of the operation mold 60 is a flexible circuit. A method of contacting and fixing the upper surface of the substrate 20 may also be used. In short, at least a portion in the vicinity of the connecting portion 30 of the flexible circuit board 20 (not necessarily the base portion of the connecting portion 30 or a surrounding portion thereof) and the mounting portion 41 may be connected to a desired fixing means 80, What is necessary is just to fix by 81. As a result, the movable member attachment portion 31 to which the operation member 60 is attached is attached to the stationary side member including the flexible circuit board 20 and the base 10 at two locations of the connection portion 30 and the attachment portion 41 that are opposed to each other by 180 °. That's right. Note that the operation member 60 is attached to the connection portion 30 and the attachment portion 41 by giving both the connection portion 30 and the attachment portion 41 a predetermined bending so that the operation member 60 can move (in this embodiment, move up and down). It is supposed to be installed in the state.

以上のように構成されたスイッチ機構１−１において、操作部材６０の操作部６５を真下に向けて押圧すると、操作部材６０の押圧部７３がスイッチ２１を構成する反転板３７を反転し、一対のスイッチパターン２３，２５間をオンする。操作部材６０への押圧を解除すれば、操作部材６０が上昇して反転板３７は元の形状に自動復帰し、スイッチ２１はオフする。そして操作部材６０が操作されていない、いわゆる無負荷状態において操作部材６０は、連結部３０と取付部４１の二ヶ所で支持されているので、操作部材６０の姿勢は所定の姿勢（この実施形態の場合は直立状態）を維持する。即ちこの実施形態においては、フレキシブル回路基板２０に設けた取付部４１を静止側部材に取り付けるという簡単な構造・取付作業だけで、別途操作部材６０のフレキシブル回路基板２０上への保持手段を設けなくても操作部材６０を保持でき、同時に別途操作部材６０のガイド機構を設けなくても操作部材６０を所定の姿勢に維持することができる。   In the switch mechanism 1-1 configured as described above, when the operation portion 65 of the operation member 60 is pressed downward, the pressing portion 73 of the operation member 60 reverses the reversing plate 37 constituting the switch 21, and a pair The switch patterns 23 and 25 are turned on. When the pressure on the operation member 60 is released, the operation member 60 is raised, the reversing plate 37 automatically returns to its original shape, and the switch 21 is turned off. And since the operation member 60 is supported by two places of the connection part 30 and the attachment part 41 in what is called a no-load state in which the operation member 60 is not operated, the attitude | position of the operation member 60 is a predetermined attitude | position (this embodiment) In the case of, maintain an upright state). That is, in this embodiment, only the simple structure and mounting work of mounting the mounting portion 41 provided on the flexible circuit board 20 to the stationary member, and no separate holding means for holding the operation member 60 on the flexible circuit board 20 is provided. In this case, the operation member 60 can be held, and at the same time, the operation member 60 can be maintained in a predetermined posture without providing a separate guide mechanism for the operation member 60.

For example, if the load necessary for reversing the reversing plate 97 is smaller than the load necessary for reversing the reversing plate 37, the reversing plate 97 is first reversed by pressing the key top 100. When the second switch 95 is turned on and the key top 100 is further pressed, the operation tool 60 is also lowered, the reversing plate 37 is reversed, and the switch 21 is turned on. When the pressing on the key top 100 is released, the switches are turned off in the order of the switch 21 and the second switch 95. On the other hand, in a so-called no-load state in which the key top 100 and the operation type object 60 are not operated, the operation member 60 is supported at two locations of the connecting portion 30 and the attachment portion 41 as in the first and second embodiments.

多方向揺動型スイッチ機構１−４の組み立て方法の一例を説明すると、まず予め操作つまみ２１０を覆い部１８０の上側からその係止用開口１８１に挿入することで、覆い部１８０の各切り欠き１８３に操作つまみ２１０の各突出部２０７を挿入し、同時に覆い部１８０の各貫通孔１８５に操作つまみ２１０の各挿入突部２０９を挿入して各挿入突部２０９の先端を熱カシメして操作つまみ２１０と覆い部１８０とを一体化しておく。一方発光素子９０を取り付けた可動部材取付部３１の上下を操作部形成部６１と押圧部形成部７１とによって挟み込み、その際操作部形成部６１の各固定部６１９を可動部材取付部３１の貫通部３１１を通して押圧部形成部７１の各挿入固定部６２１に挿入し、その先端を押圧部形成部７１の下面で熱カシメし、これによって可動部材取付部３１を挟持した状態で操作部形成部６１と押圧部形成部７１とを一体化して操作部材６０を組み立てる。このとき発光素子９０は発光素子収納部６１５内に位置する。そしてこの操作部材６０を連結部３０の部分を折り曲げることにて連結部３０を介して図８に示すようにフレキシブル回路基板２０上に配置した状態でフレキシブル回路基板２０を基台１０上に設置し、さらに操作部材６０の上にスイッチ作動部材１２０とケース１４０とケース取付部材１６０とを被せ、その際ケース取付部材１６０の各アーム部１６５をケース１４０の各ガイド溝１４７に挿入し、さらに各アーム部１６５の先端をフレキシブル回路基板２０の各固定部３２及び切欠き部２０３を介して基台１０の各取付部１３に挿入し、それらの先端を図９に示すように外方向（多方向揺動型スイッチ機構１−４から離れる方向）に向けて折り曲げて固定する。このとき、フレキシブル回路基板２０の一つの固定部３２の上には、取付部４１の固定部３５が重ねられているので、この固定部３２と同時に固定部３５にもアーム部１６５が挿入され、取付部４１は他の固定部３２の部分と同様に、ケース１４０の押圧部１４９によって基台１０に強固に押し付けられ、これによって取付部４１及び連結部３０のフレキシブル回路基板２０の近傍部分（必ずしも連結部３０の根元部分でなくても良く、その周囲部分であっても良い）は固定される。つまり可動部材取付部３１に取り付けられた操作部材６０は、連結部３０と取付部４１の複数箇所によって支持された状態でフレキシブル回路基板２０上に保持されている。なお連結部３０と取付部４１による操作部材６０の取り付けは、操作部材６０が可動（この実施形態では上下動と揺動）し得る程度の撓みを連結部３０と取付部４１が有した状態での取り付けとしている。そして覆い部１８０と一体化した操作つまみ２１０の下面から突出する導光部材２０２を、操作部材６０の挿入取付部６１３に挿入すれば、この多方向揺動型スイッチ機構１−４が完成する。   An example of a method for assembling the multi-directional oscillating switch mechanism 1-4 will be described. First, the operation knob 210 is inserted into the locking opening 181 from the upper side of the cover portion 180 in advance, so that each notch of the cover portion 180 is cut. Each protrusion 207 of the operation knob 210 is inserted into 183, and at the same time, each insertion protrusion 209 of the operation knob 210 is inserted into each through-hole 185 of the cover 180, and the tip of each insertion protrusion 209 is thermally crimped. The knob 210 and the cover part 180 are integrated. On the other hand, the upper and lower sides of the movable member attaching portion 31 to which the light emitting element 90 is attached are sandwiched between the operation portion forming portion 61 and the pressing portion forming portion 71, and each fixing portion 619 of the operation portion forming portion 61 is penetrated through the movable member attaching portion 31. The operation portion forming portion 61 is inserted into each insertion fixing portion 621 of the pressing portion forming portion 71 through the portion 311, and the tip thereof is heat caulked with the lower surface of the pressing portion forming portion 71, thereby holding the movable member mounting portion 31. And the pressing portion forming portion 71 are integrated to assemble the operation member 60. At this time, the light emitting element 90 is located in the light emitting element storage portion 615. Then, the flexible circuit board 20 is installed on the base 10 in a state where the operation member 60 is arranged on the flexible circuit board 20 as shown in FIG. Further, the switch actuating member 120, the case 140, and the case mounting member 160 are covered on the operation member 60. At this time, each arm portion 165 of the case mounting member 160 is inserted into each guide groove 147 of the case 140, and each arm The tips of the portions 165 are inserted into the mounting portions 13 of the base 10 through the fixing portions 32 and the notches 203 of the flexible circuit board 20, and the tips of the portions 165 are outward (multi-directional swinging) as shown in FIG. It is bent and fixed toward the direction away from the dynamic switch mechanism 1-4. At this time, since the fixing portion 35 of the mounting portion 41 is overlaid on the one fixing portion 32 of the flexible circuit board 20, the arm portion 165 is inserted into the fixing portion 35 simultaneously with the fixing portion 32, The mounting portion 41 is firmly pressed against the base 10 by the pressing portion 149 of the case 140 in the same manner as the other fixing portion 32, whereby the mounting portion 41 and the connection portion 30 in the vicinity of the flexible circuit board 20 (not necessarily The base portion of the connecting portion 30 does not have to be the surrounding portion and may be a peripheral portion thereof). That is, the operating member 60 attached to the movable member attaching portion 31 is held on the flexible circuit board 20 in a state where it is supported by a plurality of locations of the connecting portion 30 and the attaching portion 41. The operating member 60 is attached by the connecting portion 30 and the attaching portion 41 in a state where the connecting portion 30 and the attaching portion 41 have such a degree of bending that the operating member 60 can move (in this embodiment, up and down and swing). It is supposed to be installed. Then, when the light guide member 202 protruding from the lower surface of the operation knob 210 integrated with the cover portion 180 is inserted into the insertion mounting portion 613 of the operation member 60, the multi-directional oscillating switch mechanism 1-4 is completed.

そして操作つまみ２１０を真下に押圧すれば、スイッチ作動部材１２０は元の位置のままの状態にて操作部材６０のみが下降してその押圧部７３が反転板３７を反転してスイッチ２１をオンする。操作つまみ２１０への押圧を解除すれば、反転板３７が元の形状に自動復帰してスイッチ２１がオフすると同時に、操作部材６０や操作つまみ２１０も元の位置に自動復帰する。一方操作つまみ２１０を揺動すると、これと一体に操作部材６０及びスイッチ作動部材１２０も揺動し（このときケース１４０の当接部１４５上をスイッチ作動部材１２０の摺接面１２１が摺動する）、下降した側のスイッチ作動部材１２０の押圧部１２５によってこれに対向している反転板３７Ａが反転されてスイッチ２１Ａがオンする。操作つまみ２１０の揺動を解除すれば、反転板３７Ａが元の形状に自動復帰してスイッチ２１Ａがオフすると同時に、操作部材６０や操作つまみ２１０も元の位置に自動復帰する。そしてこの実施形態においても、前記各実施形態と同様に、操作部材６０が無負荷状態の時は、操作部材６０は、フレキシブル回路基板２０に連結される連結部３０と取付部４１とによって支持されているので、操作部材６０（及びこれと一体の操作つまみ２１０やスイッチ作動部材１２０）の姿勢は所定の姿勢（この実施形態の場合は直立状態）を維持する。即ちこの実施形態においても、別途操作部材６０のフレキシブル回路基板２０上への保持手段を設けなくても操作部材６０を保持でき、同時に別途操作部材６０のガイド機構を設けなくても操作部材６０を所定の姿勢に維持することができる。   If the operation knob 210 is pressed directly below, only the operation member 60 is lowered while the switch operating member 120 remains in its original position, and the pressing portion 73 reverses the reversing plate 37 to turn on the switch 21. . When the pressure on the operation knob 210 is released, the reversing plate 37 automatically returns to its original shape and the switch 21 is turned off. At the same time, the operation member 60 and the operation knob 210 are also automatically returned to their original positions. On the other hand, when the operation knob 210 is swung, the operation member 60 and the switch actuating member 120 are also swung together with this (the slide contact surface 121 of the switch actuating member 120 slides on the contact portion 145 of the case 140 at this time). ), The reversing plate 37A facing it is reversed by the pressing portion 125 of the lowered switch actuating member 120, and the switch 21A is turned on. If the swing of the operation knob 210 is released, the reversing plate 37A automatically returns to the original shape and the switch 21A is turned off, and at the same time, the operation member 60 and the operation knob 210 are automatically returned to their original positions. Also in this embodiment, as in the above embodiments, when the operation member 60 is in an unloaded state, the operation member 60 is supported by the connecting portion 30 and the attachment portion 41 that are connected to the flexible circuit board 20. Therefore, the operation member 60 (and the operation knob 210 and the switch operation member 120 integrated with the operation member 60) maintain a predetermined posture (in this embodiment, an upright state). That is, also in this embodiment, the operation member 60 can be held without separately providing the holding member for holding the operation member 60 on the flexible circuit board 20, and at the same time, the operation member 60 can be installed without providing the guide mechanism for the operation member 60 separately. The predetermined posture can be maintained.

The The sliding contact pattern 205 (see FIG. 8) provided on the flexible circuit board 20 constitutes a part of the rotary electronic component 300, and a slider attached to the sliding type object of the rotary electronic component 300 is provided thereon. The desired electrical output is changed by sliding the. Also in this embodiment, the number of connecting portions 30 and mounting portions 41 may be plural.

FIG. 12 is a schematic cross-sectional view of a switch mechanism (in this embodiment, a two-stage press switch mechanism) 1-6 according to the sixth embodiment of the present invention. In the switch mechanism 1-6 shown in FIG. 12, the same parts as those in the switch mechanism 1-1 according to the first embodiment are denoted by the same reference numerals. Note that matters other than those described below are the same as those in the first embodiment. Similarly to the switch mechanism 1-1, the switch mechanism 1-6 is a base 10 that is a stationary member, and a flexible member that is a stationary member that is installed on the base 10 and is provided with a switch 21 at a predetermined position. The circuit board 20 and the operation member 60 which is a movable member installed on the flexible circuit board 20 are comprised, The movable member attaching part 31 provided in the flexible circuit board 20 via the connection part 30 is comprised. The operation member 60 is attached to the movable member attachment portion 31 in a state where the operation member 60 is disposed on the upper surface side of the flexible circuit substrate 20 via the connecting portion 30, and the attachment portion 41 provided on the movable member attachment portion 31 is attached to the flexible circuit substrate 20. The operation member 60 is configured to be maintained in a predetermined posture by being attached to a stationary side member including And this switch mechanism 1-6 is different from the switch mechanism 1-1 in that the pressing member forming portion 71 of the operating member 60 shown in the first embodiment is omitted, and the operating member 60 is replaced only by the operating portion forming portion 61. The point which comprised, the point which attached the movable member attachment part 31 to the lower surface of the operation member 60 by inserting the engagement part 67 in the latching | locking part 33, and heat-crimped the front-end | tip, and the shape of the operation member 60 are key tops. As shown in FIG. 2, a switch 21 which is an electrical functional part including switch patterns 23 and 25 and a reversing plate 37 is provided on the flexible circuit board 20 and the movable member attaching part 31 ( In FIG. 12, the switch 21-2, which is an electrical function part composed of the switch patterns 23 and 25 and the reversing plate 37-2 as shown in FIG.

Further, the drawing pattern drawn out from the switch 21-2 is drawn out from the movable member mounting portion 31 through the connecting portion 30 to the flexible circuit board 20, as in the fifth embodiment.

ここで前記押圧部５１はフレキシブル回路基板２０と可動部材取付部３１の間に設置される押圧部形成部材５０の一部として設置されている。即ち押圧部形成部材５０は、反転板３７の外径よりも外側にリング状に設置される取付基部５３と、可撓性を有する程度に薄板状に形成されたヒンジ部５５と、ヒンジ部５５によって取付基部５３の中央に支持される柱状の押圧部５１とを合成樹脂を一体成形することによって構成されている。そして取付基部５３を反転板３７の外周を覆うようにフレキシブル回路基板２０上に取り付けている。取付構造は、例えば図１２に示すように、取付基部５３の下面から突出する小突起状の取付突起５７をフレキシブル回路基板２０と基台１０に設けた小孔に挿入してその先端を熱カシメすること等によって行う。   Here, the pressing portion 51 is installed as a part of the pressing portion forming member 50 installed between the flexible circuit board 20 and the movable member attaching portion 31. That is, the pressing portion forming member 50 includes a mounting base portion 53 that is installed in a ring shape outside the outer diameter of the reversing plate 37, a hinge portion 55 that is formed in a thin plate shape so as to be flexible, and the hinge portion 55. The columnar pressing portion 51 supported at the center of the mounting base 53 is formed by integrally molding synthetic resin.

Further, by pressing the operation member 60, the pressing portion 51 reverses the reversing plate 37 and the switch 21 is turned on. When the pressing on the operation member 60 is released, the operation member 60 rises, the reversing plates 37 and 37-2 automatically return to their original shapes in order, and the switches 21 and 21-2 turn off in turn. Similarly to the first embodiment, in a so-called no-load state in which the operation member 60 is not operated, the operation member 60 is supported at two locations of the connecting portion 30 and the attachment portion 41, and thus the operation member 60. Is maintained in a predetermined posture (in this embodiment, in an upright state). That is, the operation member 60 can be held without providing a separate holding means for the operation member 60 on the flexible circuit board 20, and at the same time, the operation member 60 is maintained in a predetermined posture without providing a separate guide mechanism for the operation member 60. be able to.

It is only the point which becomes the structure which provided the press part 51 in the position which opposes both said inversion plates 37 and 37-2. That is, as in the sixth embodiment, the pressing portion forming member 50 is structured by providing the pressing portion 51 in the synthetic resin film, instead of being formed of an integrally molded product of synthetic resin. The pressing portion 51 may be a resin molded product, or may be formed by applying a resin as a paint. The pressing portion mounting portion 59 made of this synthetic resin film is preferably connected to the flexible circuit board 20 or the movable member mounting portion 31 at a predetermined position (not shown) for the purpose of reducing the number of components and facilitating assembly. . Moreover, if the surrounding part of the switches 21 and 21-2 of the pressing portion mounting portion 59 is attached to the movable member mounting portion 31 or the flexible circuit board 20, the position of the pressing portion 51 does not deviate from the normal position, and always. It is preferable because the switches 21 and 21-2 can be accurately pressed. The switch pressing operation of the switch mechanism 1-7 is the same as that of the switch mechanism 1-6. Similarly to the sixth embodiment, in a so-called no-load state in which the operation member 60 is not operated, the operation member 60 is supported at the two portions of the connecting portion 30 and the attachment portion 41, and thus the operation member 60. Is maintained in a predetermined posture (in this embodiment, in an upright state). That is, the operation member 60 can be held without providing a separate holding means for the operation member 60 on the flexible circuit board 20, and at the same time, the operation member 60 is maintained in a predetermined posture without providing a separate guide mechanism for the operation member 60. be able to.
