Description

押圧操作を受ける操作装置及びこれを備えたスイッチ装置Operation device for receiving pressing operation and switch device provided with the same
　本発明は、自動車等の車室内パネルや各種電子機器の操作パネルに適用可能な押圧操作式の操作装置、及びこれを備えたスイッチ装置に関するものである。 The present invention relates to a press operation type operation device applicable to a vehicle interior panel of an automobile or the like and an operation panel of various electronic devices, and a switch device including the same.
　自動車等の車室内パネルや各種電子機器の操作パネルには、操作部材として、当該操作パネルの裏側に設けられたスイッチ素子を押圧するための操作ボタンが多用されている。この操作ボタンは、前記車室内パネル等に含まれる保持部材によって、前記押圧操作の方向にスライド可能となるように支持され、押圧操作を受けたときに前記スイッチ素子をその押圧操作方向に押圧すると同時にその押圧操作方向と反対の方向の反力を当該スイッチ素子から受ける。 An operation button for pressing a switch element provided on the back side of the operation panel is often used as an operation member on a vehicle interior panel of an automobile or the like and an operation panel of various electronic devices. The operation button is supported by a holding member included in the vehicle interior panel or the like so as to be slidable in the direction of the pressing operation, and when the switch element is pressed in the pressing operation direction when the pressing operation is received. At the same time, a reaction force in the direction opposite to the pressing operation direction is received from the switch element.
　このような操作ボタンを含む操作装置として、特許文献１に開示されるものが知られている。その主要構成を図６に示す。図示の操作装置は、操作ボタン８０と、これを保持する保持部材である操作パネル９０とを備え、この操作パネル９０の裏側に回路基板１００が設けられるとともに、当該回路基板１００上に複数のスイッチ素子１０１，１０２が実装されている。 As an operation device including such operation buttons, one disclosed in Patent Document 1 is known. The main configuration is shown in FIG. The illustrated operation device includes an operation button 80 and an operation panel 90 that is a holding member for holding the operation button. A circuit board 100 is provided on the back side of the operation panel 90, and a plurality of switches are provided on the circuit board 100. Elements 101 and 102 are mounted.
　前記操作ボタン８０は、外部から押圧操作を受けるボタン本体８２と、このボタン本体８２から押圧操作方向（図では下方向）に延びる複数の押圧部８３，８４とを有する。さらに、前記ボタン本体８２の両端からは前記押圧部８４と平行な方向に被係止片８６が突出し、各被係止部８６の先端には被係止爪８６ａが形成されている。 The operation button 80 includes a button main body 82 that receives a pressing operation from the outside, and a plurality of pressing portions 83 and 84 that extend from the button main body 82 in the pressing operation direction (downward in the drawing). Further, a locking piece 86 protrudes from both ends of the button body 82 in a direction parallel to the pressing portion 84, and a locking claw 86 a is formed at the tip of each locking portion 86.
　前記操作パネル９０は、前記押圧操作方向に開口する筒状の保持部９３，９４を有し、これらの保持部９３，９４に前記押圧部８３，８４がパネル表面側（図では上側）から挿通される。この挿通状態で前記保持部９３，９４は前記押圧部８３，８４を前記押圧操作方向に案内するように保持する。さらに、前記操作パネル９０には前記各被係止爪８６ａよりも小さな貫通孔９６が形成され、これらの貫通孔９６に対して前記各被係止爪８６ａがパネル表面側から強制的に押し込まれて操作パネル９０の裏側に至っている。 The operation panel 90 includes cylindrical holding portions 93 and 94 that open in the pressing operation direction, and the pressing portions 83 and 84 are inserted into the holding portions 93 and 94 from the panel surface side (upper side in the drawing). Is done. In this inserted state, the holding portions 93 and 94 hold the pressing portions 83 and 84 so as to guide them in the pressing operation direction. Further, the operation panel 90 is formed with through holes 96 smaller than the respective engaged claws 86a, and the respective engaged claws 86a are forced into the through holes 96 from the panel surface side. To the back side of the operation panel 90.
　前記各スイッチ素子１０１，１０２は、前記押圧部８３，８４の先端により押圧されることが可能な位置に設けられ、かつ、その押圧時に前記押圧操作方向と反対の方向の反力を押圧部８３，８４にそれぞれ与える。この反力は、前記被係止爪８６ａを前記操作パネル９０の裏面に押し当て、その位置に操作パネル９０を保持する。この状態（図示の状態）が、前記操作ボタン８０に押圧操作力が与えられていない非操作状態であり、この状態から前記操作ボタン８０のボタン本体８２が前記反力に抗して押圧操作されることにより、前記各押圧部８３，８４が前記スイッチ素子１０１，１０２をさらに押圧してこれらのスイッチ素子１０１，１０２をオンに切換える。 Each of the switch elements 101 and 102 is provided at a position where the switch elements 101 and 102 can be pressed by the tips of the pressing portions 83 and 84, and the pressing portion 83 applies a reaction force in a direction opposite to the pressing operation direction at the time of pressing. , 84 respectively. This reaction force presses the to-be-latched claw 86a against the back surface of the operation panel 90, and holds the operation panel 90 in that position. This state (the state shown in the figure) is a non-operation state in which no pressing operation force is applied to the operation button 80. From this state, the button body 82 of the operation button 80 is pressed against the reaction force. Thus, the pressing portions 83 and 84 further press the switch elements 101 and 102 to turn on the switch elements 101 and 102.
　この図６に示される操作装置の課題は、構造の簡素化及び小型化、並びに押圧操作解除時の跳ね返り音の低減である。具体的に、当該操作装置では、操作ボタン８０において押圧部８３，８４から離れた位置に当該押圧部８３，８４とは別の被係止片８６が形成されなければならず、これが操作ボタン８０の構造の簡素化及び小型化を妨げる。また、前記操作ボタン８０の押圧操作後にこれが解除されると、スイッチ素子１０１，１０２の反力で被係止爪８６ａが操作パネル９０の裏面に強く当たって音（いわゆる跳ね返り音）を発生させる。この跳ね返り音は操作装置の質感の向上を妨げる。
特開２００７－２６６７５４号公報 Problems of the operating device shown in FIG. 6 are simplification and downsizing of the structure, and reduction of the bounce sound when the pressing operation is released. Specifically, in the operating device, a locked piece 86 different from the pressing portions 83 and 84 must be formed at a position away from the pressing portions 83 and 84 in the operating button 80, and this is the operation button 80. This prevents the simplification and downsizing of the structure. Further, when the operation button 80 is released after the pressing operation, the latching claw 86a strongly strikes the back surface of the operation panel 90 by the reaction force of the switch elements 101 and 102 to generate a sound (so-called bounce sound). This bounce sound hinders improvement in the texture of the operating device.

Therefore, the holding panel 10B needs a structure for locking the operation buttons 20A to 20E.
　また、前記各操作ボタン２０Ａ～２０Ｅは、前記各スイッチ素子の押圧操作時（すなわち弾性変位部５４の押圧操作時）に当該スイッチ素子から反力（薄肉部５３による弾性変位部５４の弾性復帰力）を受ける。従って、前記保持パネル１０Ｂには、当該押圧操作の解除時に前記反力に抗して前記各操作ボタン２０Ａ～２０Ｅを所定の復帰位置に係止するための構造も必要である。 Further, each of the operation buttons 20A to 20E receives a reaction force (elastic return force of the elastic displacement portion 54 by the thin portion 53) from the switch element when the switch element is pressed (that is, when the elastic displacement portion 54 is pressed). ) Therefore, the holding panel 10B also needs a structure for locking the operation buttons 20A to 20E at a predetermined return position against the reaction force when the pressing operation is released.
　この実施の形態では、前記の双方の係止が図３～図５に示されるような簡素な構造によって実現される。 In this embodiment, both of the above-described locking are realized by a simple structure as shown in FIGS.
　まず、各操作ボタン２０Ａ～２０Ｅにおいては、その押圧部２４の先端部から前記押圧操作方向と直交する方向（すなわち回路基板４０と平行な方向）に被係止部２６が突出している。そして、この被係止部２６が前記押圧部２４の先端とともに接触部、すなわち前記弾性変位部５４のパネル表側の端面と接触してこれを押圧する部分を構成する。 First, in each of the operation buttons 20A to 20E, the locked portion 26 protrudes from the distal end portion of the pressing portion 24 in a direction orthogonal to the pressing operation direction (that is, a direction parallel to the circuit board 40). And this to-be-latched part 26 comprises the part which contacts the contact part, ie, the end surface of the panel front side of the said elastic displacement part 54, with the front-end | tip of the said press part 24, and presses this.
　一方、前記保持パネル１０Ｂの保持部において、前記被係止部２６が突出する側の保持ブロックの側面からそれぞれ肩部１０ｆが突出し、各肩部１０ｆから前記回路基板４０側に向かって（すなわち前記押圧操作方向に）撓み片１６が延びている。これらの撓み片１６は、それぞれ、図３および図４に示すように、前記肩部１０ｆから前記操作ボタン２０Ａ～２０Ｅの押圧操作方向に沿って延びる基部１６ａと、この基部１６ａの先端から前記被操作部２６に近づく側（図３では右側）に斜め向きに延びる傾斜部１６ｂとを有し、この傾斜部１６ｂの先端が前記被係止部２６に対して前記回路基板４０と反対の側から当接可能な係止部１６ｃを構成している。 On the other hand, in the holding portion of the holding panel 10B, shoulder portions 10f protrude from the side surfaces of the holding block on the side where the locked portion 26 protrudes, and from the shoulder portions 10f toward the circuit board 40 (that is, A bending piece 16 extends in the direction of the pressing operation. As shown in FIGS. 3 and 4, each of the bending pieces 16 includes a base portion 16a extending from the shoulder portion 10f along the pressing operation direction of the operation buttons 20A to 20E, and a tip of the base portion 16a. An inclined portion 16b that extends obliquely on the side approaching the operation portion 26 (right side in FIG. 3), and the tip of the inclined portion 16b from the side opposite to the circuit board 40 with respect to the locked portion 26. An abutting locking portion 16c is configured.
　前記各撓み片１６の形状及び位置は、次の条件Ａ～Ｃを満たすように設定されている。 The shape and position of each bending piece 16 are set so as to satisfy the following conditions A to C.
　Ａ．図４に示されるように、各操作ボタン（図４では操作ボタン２０Ｃ，２０Ｅのみ図示）の押圧部２４が保持パネル１０Ｂの保持部に対して弾性変位部５４等からなるスイッチ素子と反対の側（図２及び図３では上側、図４では奥側）から挿入されるのに伴い、その押圧部２４から突出する被係止部２６とこれに対応する撓み片１６とが接触し、この接触により撓み片１６が前記被係止部２６から退避する向きに撓む。 A. As shown in FIG. 4, the pressing part 24 of each operation button (only the operation buttons 20C and 20E are shown in FIG. 4) is on the side opposite to the switch element comprising the elastic displacement part 54 and the like with respect to the holding part of the holding panel 10B. As inserted from the upper side (in FIG. 2 and FIG. 3, the rear side in FIG. 4), the locked portion 26 protruding from the pressing portion 24 and the corresponding flexure piece 16 come into contact with each other. As a result, the bending piece 16 bends in a direction to retract from the locked portion 26.
　Ｂ．図５に示されるように前記被係止部２６が前記撓み片１６を乗り越えた位置で、当該撓み片１６の係止部１６ｃが当該被係止部２６に対して前記スイッチ素子と反対の側から当接することにより、各操作ボタンの逆行を防ぐ。すなわち、当該操作ボタンが前記スイッチ素子から離れる方向への移動域を規制する。また、前記係止部１６ｃは、前記基部１６ａに対する前記傾斜部１６ｂの傾斜分だけ前記押圧操作方向と平行な方向から傾いた角度で前記被係止部２６に当接する。 B. As shown in FIG. 5, the locking portion 16 c of the bending piece 16 is located on the side opposite to the switch element with respect to the locking portion 26 at a position where the locking portion 26 has overcome the bending piece 16. By making contact with each other, the reverse operation of each operation button is prevented. That is, the movement range of the operation button in the direction away from the switch element is restricted. Further, the locking portion 16c contacts the locked portion 26 at an angle inclined from a direction parallel to the pressing operation direction by an amount of inclination of the inclined portion 16b with respect to the base portion 16a.
　Ｃ．図２に示されるように前記本体パネル１０Ａに回路基板４０が固定され、かつ、前記Ｂのように各操作ボタン２０Ａ～２０Ｅが装着された保持パネル１０Ｂが本体パネル１０Ａに組付けられることにより、図３に示されるように、前記押圧部２４の先端及び前記被係止部２６からなる接触部が、押圧スイッチ用弾性材５０の弾性変位部５４を軽く押圧して僅かに弾性変位させる。換言すれば、押圧変位部５４がその反力によって前記被係止部２６を前記係止部１６ｃに軽く押付けるように、当該押圧変位部５４と撓み片１６との相対位置が設定される。 C. As shown in FIG. 2, the circuit board 40 is fixed to the main body panel 10A, and the holding panel 10B to which the operation buttons 20A to 20E are attached as shown in B is assembled to the main body panel 10A. As shown in FIG. 3, the contact portion formed by the tip of the pressing portion 24 and the locked portion 26 lightly presses the elastic displacement portion 54 of the elastic member 50 for pressing switch and slightly elastically displaces it. In other words, the relative position between the pressing displacement portion 54 and the bending piece 16 is set so that the pressing displacement portion 54 lightly presses the locked portion 26 against the locking portion 16c by the reaction force.
　以上説明した装置では、操作ボタン２０Ａ～２０Ｅの押圧部２４から突出する被係止部２６と、保持パネル１０Ｂに形成された複数の撓み片１６との組合せが、保持パネル１０Ｂへの操作ボタン２０Ａ～２０Ｅの容易な装着を実現するのに加え、当該保持パネル１０Ｂが前記本体パネル１０Ａに組付けられた後における、押圧操作解除時での操作ボタン２０Ａ～２０Ｅの位置規制と、その跳ね返り音の抑制とを同時に実現する。 In the apparatus described above, the combination of the locked portion 26 protruding from the pressing portion 24 of the operation buttons 20A to 20E and the plurality of flexure pieces 16 formed on the holding panel 10B results in the operation button 20A to the holding panel 10B. In addition to realizing easy mounting of 20E, the position of the operation buttons 20A to 20E when the pressing operation is released after the holding panel 10B is assembled to the main body panel 10A, and the rebound sound thereof Achieve suppression at the same time.
　具体的に、当該操作ボタン２０Ａ～２０Ｅの動作を説明すると、まず、図２に示される位置（押圧操作前の位置）から操作ボタン２０Ａ～２０Ｅのいずれかのボタン本体２２が指等で押圧されることにより、その押圧操作方向（回路基板４０に向かう方向）に当該操作ボタンがスライドし、その押圧部２４の先端および被係止部２６により構成される接触部が弾性変位部５４をその反力に抗して前記押圧操作方向に押圧して弾性変位させる。そして、この弾性変位部５４の裏面に設けられた操作側接点５６が回路基板４０上の基板側接点４２に接触した時点で、当該弾性変位部５４等からなるスイッチ素子が「開」から「閉」に切換えられる。 Specifically, the operation of the operation buttons 20A to 20E will be described. First, any one of the button bodies 22 of the operation buttons 20A to 20E is pressed with a finger or the like from the position shown in FIG. 2 (position before the pressing operation). As a result, the operation button slides in the pressing operation direction (the direction toward the circuit board 40), and the contact portion constituted by the tip of the pressing portion 24 and the locked portion 26 causes the elastic displacement portion 54 to move against the elastic displacement portion 54. It is elastically displaced by pressing in the pressing operation direction against the force. When the operation-side contact 56 provided on the back surface of the elastic displacement portion 54 comes into contact with the substrate-side contact 42 on the circuit board 40, the switch element including the elastic displacement portion 54 and the like is changed from “open” to “closed”. Is switched to.
　その後、前記押圧操作が解除されると、前記弾性変位部５４の弾性復帰力により前記押圧部２４及び被係止部２６が押し返され、これらは当該被係止部２６が前記撓み片１６の係止部１６ｃに当接する位置で止まる。従って、この位置に前記操作ボタンの戻り位置が規定される。さらに、その当接時における前記係止部１６ｃの微小な撓み変位が、当該当接に起因する音（いわゆる跳ね返り音）の発生を有効に抑制する。すなわち、前記撓み片１６の撓みが、前記保持パネル１０Ｂへの操作パネル２０Ａ～２０Ｅの装着の容易化と、前記跳ね返り音の抑制との双方に貢献する。特に、この実施の形態に係る撓み片１６の係止部１６ｃは、前記操作ボタン２０Ａ～２０Ｅの挿入方向に対して傾斜する方向から前記被係止部２６に当接するので、前記当接時に当該撓み片１６が撓みやすい。 Thereafter, when the pressing operation is released, the pressing portion 24 and the locked portion 26 are pushed back by the elastic return force of the elastic displacement portion 54, and the locked portion 26 of the bending piece 16 is pushed back. It stops at a position where it comes into contact with the locking portion 16c. Therefore, the return position of the operation button is defined at this position. Further, the minute deflection displacement of the locking portion 16c at the time of the contact effectively suppresses the generation of a sound (so-called bounce sound) caused by the contact. That is, the bending of the bending piece 16 contributes to both the ease of mounting the operation panels 20A to 20E to the holding panel 10B and the suppression of the bounce sound. In particular, the locking portion 16c of the bending piece 16 according to this embodiment contacts the locked portion 26 from a direction inclined with respect to the insertion direction of the operation buttons 20A to 20E. The bending piece 16 is easily bent.
　この撓み片１６の形状は、例えば前記保持パネル１０Ｂの肩部１０ｆから直線状に斜め向きに延びるものであってもよいが、図示のように、前記操作ボタンの押圧操作方向に沿って延びる基部１６ａと、この基部１６ａの先端から前記被係止部２６に近づく斜め向きに延びる傾斜部１６ｂとを有し、この傾斜部の先端が前記係止部１６ｃを構成するものでは、限られたスペースの中で当該係止部１６ｃの前記被係止部２６に対する入射角度をより大きくすることが可能であり、これによって撓み片１６の撓みをより促進し、その吸音効果を顕著にすることができる。 The shape of the flexure piece 16 may, for example, extend linearly and obliquely from the shoulder portion 10f of the holding panel 10B. However, as shown in the drawing, the base portion extends along the pressing operation direction of the operation button. 16a and an inclined portion 16b that extends obliquely from the tip of the base portion 16a toward the locked portion 26, and the tip of the inclined portion constitutes the locking portion 16c. Among them, it is possible to increase the incident angle of the locking portion 16c with respect to the locked portion 26, thereby further promoting the bending of the bending piece 16 and making the sound absorbing effect remarkable. .
　また、前記被係止部２６は前記押圧部２４から突出するものであるため、例えば前記図６に示されるように押圧部８３，８４から離れた別の位置に被係止片８６が形成される従来装置に比べ、操作装置の構造の簡素化及び小型化が進められる。換言すれば、簡素かつコンパクトな構造で、前記の優れた効果が実現される。 Further, since the locked portion 26 protrudes from the pressing portion 24, for example, a locked piece 86 is formed at another position away from the pressing portions 83 and 84 as shown in FIG. Compared to the conventional device, the structure of the operating device is simplified and downsized. In other words, the above-described excellent effect is realized with a simple and compact structure.
　特に、前記各図に示される装置のように、保持パネル１０Ｂが複数の操作ボタン２０Ａ～２０Ｅを保持するとともに当該各操作ボタン２０Ａ～２０Ｅの被係止部２６をそれぞれ係止する複数の撓み片１６を有するものでは、複数の操作ボタン２０Ａ～２０Ｅのそれぞれについて押圧部２４および被係止部２６の位置が共通化されるため、装置全体の構造の簡素化及び小型化がより著しいものとなる。 In particular, as in the devices shown in the drawings, the holding panel 10B holds a plurality of operation buttons 20A to 20E and a plurality of flexure pieces that respectively lock the locked portions 26 of the operation buttons 20A to 20E. 16 has a common position of the pressing portion 24 and the locked portion 26 for each of the plurality of operation buttons 20A to 20E, and therefore simplification and downsizing of the structure of the entire apparatus become more remarkable. .
　なお、前記被係止部２６が前記押圧部２４から突出する位置は、適宜設定可能であり、例えば当該押圧部２４の先端よりもスイッチ素子から離れた位置に被係止部２６が突設されていてもよい。しかし、図３等に示されるように被係止部２６が押圧部２４の先端から前記押圧操作方向と直交する方向に突出して当該押圧部の先端とともに接触部の一部を構成することは、押圧部２４の断面積を抑えながら前記接触部の面積（弾性変位部５４に対して接触する面積）を十分に確保することを可能にする。 The position where the locked portion 26 protrudes from the pressing portion 24 can be set as appropriate. For example, the locked portion 26 protrudes at a position farther from the switch element than the tip of the pressing portion 24. It may be. However, as shown in FIG. 3 and the like, the locked portion 26 protrudes from the tip of the pressing portion 24 in a direction perpendicular to the pressing operation direction and constitutes a part of the contact portion together with the tip of the pressing portion. It is possible to sufficiently ensure the area of the contact portion (the area in contact with the elastic displacement portion 54) while suppressing the cross-sectional area of the pressing portion 24.
　また、本発明に係る操作装置及びスイッチ装置について適用されるスイッチ素子は、図示のように回路基板４０と押圧スイッチ用弾性材５０との組合せにより構成されるものに限られない。例えば、前記回路基板またはその他の部材に固定される基部と、この基部に接点の開閉方向（押圧操作される方向）に変位可能に装着される被操作部と、前記基部と前記被操作部との間に介在して当該被操作部に被押圧時の反力を与えるばねとを具備した独立したスイッチ素子についても、本発明の適用が可能である。 Further, the switch element applied to the operation device and the switch device according to the present invention is not limited to the one configured by the combination of the circuit board 40 and the elastic material 50 for the push switch as illustrated. For example, a base that is fixed to the circuit board or other member, an operated part that is mounted on the base so as to be displaceable in a contact opening / closing direction (a direction in which a pressing operation is performed), the base, and the operated part The present invention can also be applied to an independent switch element provided with a spring interposed between them to apply a reaction force to the operated portion when pressed.
　以上のように、本発明は、押圧操作を受ける操作部材を含み、かつ、この操作部材の押圧操作が解除された時の跳ね返り音を簡素かつ小型化された構造で有効に低減させることができる操作装置及びこれを備えたスイッチ装置を提供する。 As described above, the present invention includes an operation member that receives a pressing operation, and can effectively reduce the bounce sound when the pressing operation of the operation member is released with a simple and downsized structure. An operating device and a switch device including the operating device are provided.
　具体的に、当該操作装置は、特定の押圧操作方向に押圧操作を受けることにより、所定のスイッチ素子を押圧するための操作部材と、この操作部材を当該操作部材が前記押圧操作方向に移動可能となるように保持する保持部材とを備える。前記操作部材は、前記押圧操作を受ける被操作部と、この被操作部から前記押圧操作方向に延び、その先端に前記スイッチ素子と接触する接触部を有する押圧部と、この押圧部から前記押圧操作方向と直交する方向に突出する被係止部とを有する。前記保持部材は、前記操作部材をその押圧操作方向と平行な方向に案内するように当該操作部材を保持する保持部と、この保持部から前記スイッチ素子側に向かう方向に延び、その先端が前記押圧操作方向と直交する方向に撓み変位可能な係止部を構成する撓み片とを有し、前記撓み片は、前記操作部材の押圧部が前記保持部に対して前記スイッチ素子と反対の側から挿入されるのに伴って前記被係止部と接触することによりこの被係止部から退避する向きに撓み、かつ、この撓み片を前記被係止部が乗り越えた位置で当該撓み片の係止部が当該被係止部に対して前記スイッチ素子と反対の側から当接することにより前記操作部材の前記スイッチ素子から離れる方向への移動域を規制するような位置に設けられる。 Specifically, the operating device receives a pressing operation in a specific pressing operation direction, and an operating member for pressing a predetermined switch element, and the operating member can be moved in the pressing operation direction. And a holding member for holding. The operating member includes an operated portion that receives the pressing operation, a pressing portion that extends from the operated portion in the pressing operation direction and has a contact portion that contacts the switch element at a tip thereof, and the pressing portion from the pressing portion. A locked portion protruding in a direction orthogonal to the operation direction. The holding member extends in a direction from the holding portion toward the switch element so as to guide the operating member in a direction parallel to the pressing operation direction. And a bending piece constituting a locking portion that can be deflected and displaced in a direction orthogonal to the pressing operation direction, and the bending piece is located on a side opposite to the switch element with respect to the holding portion where the pressing portion of the operation member is Is bent in the direction of retreating from the locked portion by contacting with the locked portion, and at the position where the locked portion gets over the bent piece, The locking portion is provided at a position that restricts the movement range of the operating member in the direction away from the switch element by abutting the locked portion from the side opposite to the switch element.
　この操作装置では、操作部材の押圧部から突出する被係止部と、保持部材に形成された撓み片との組合せが、保持部材への操作部材の容易な装着と、押圧操作解除時における操作部材の位置規制と、跳ね返り音の抑制とを同時に可能にする。 In this operating device, the combination of the locked portion protruding from the pressing portion of the operating member and the flexure piece formed on the holding member makes it easy to attach the operating member to the holding member and to perform the operation when releasing the pressing operation. It is possible to simultaneously control the position of the member and suppress the bounce sound.
　具体的に、前記操作部材の押圧部が前記保持部に対して前記スイッチ素子と反対の側から挿入されると、これに伴い、前記押圧部から突出する被係止部が撓み片と接触してこれを撓ませる。そして、この被係止部が前記撓み片を乗り越えたときに当該撓み片が弾性復帰してその係止部が前記被係止部に対して前記スイッチ素子と反対の側から当接することにより、この被係止部を係止するとともに、前記操作部材の前記スイッチ素子から離れる方向への移動域を規制する。しかも、前記撓み片の撓み変位は、前記操作部材の押圧操作が解除されて前記スイッチ素子の反力で前記被係止部が当該撓み片の係止部に当接したときの音（すなわち跳ね返り音）を有効に吸収する。 Specifically, when the pressing portion of the operating member is inserted from the side opposite to the switch element with respect to the holding portion, the locked portion protruding from the pressing portion comes into contact with the bending piece. Bend it. And, when this locked part gets over the bending piece, the bending piece elastically recovers, and the locking part comes into contact with the locked part from the side opposite to the switch element, While locking this to-be-latched part, the movement range to the direction away from the said switch element of the said operation member is controlled. In addition, the bending displacement of the bending piece is a sound (that is, rebounding) when the pressing operation of the operation member is released and the locked portion comes into contact with the locking portion of the bending piece by the reaction force of the switch element. Sound) is absorbed effectively.
　さらに、前記被係止部は前記押圧部から突出するものであるため、当該押圧部とは別の位置に被係止部が形成される従来装置に比べ、操作装置の構造の簡素化及び小型化が進められる。 Furthermore, since the to-be-latched portion protrudes from the pressing portion, the structure of the operating device is simplified and compact compared to the conventional device in which the to-be-latched portion is formed at a position different from the pressing portion. Will be promoted.
　前記撓み片は、その係止部が前記操作部材の押圧操作方向に対して傾斜する方向から前記被係止部に当接する形状を有することが、より好ましい。このように係止部が前記被係止部に対して斜め向きに当接することは、当該当接時における撓み片の撓みを促進し、その吸音効果をより顕著にする。 It is more preferable that the bending piece has a shape in which the locking portion comes into contact with the locked portion from a direction inclined with respect to the pressing operation direction of the operation member. In this way, the locking portion abuts against the locked portion in an oblique direction promotes the bending of the bending piece at the time of the contact, and makes the sound absorption effect more remarkable.
　特に、前記撓み片が、前記保持部から前記操作部材の押圧操作方向に沿って延びる基部と、この基部先端から前記被係止部に近づく斜め向きに延びる傾斜部とを有し、この傾斜部の先端が前記係止部を構成するものでは、当該係止部の前記被係止部に対する入射角度をより大きくして撓み片の撓みをより促進することができる。 In particular, the bending piece has a base portion that extends from the holding portion along the pressing operation direction of the operation member, and an inclined portion that extends obliquely from the distal end of the base portion and approaches the locked portion. In the case where the distal end of the first portion constitutes the locking portion, the incident angle of the locking portion with respect to the locked portion can be increased to further promote the bending of the bending piece.
　なお、前記基部が「操作部材の押圧操作方向に沿って延びる」とは、当該基部と操作部材の押圧操作方向とが完全に平行であることを限定する趣旨ではなく、当該基部の具体的な形状は限定されない。 The phrase “extending along the pressing operation direction of the operating member” does not mean that the base and the pressing operation direction of the operating member are completely parallel. The shape is not limited.
　前記被係止部が前記押圧部から突出する位置は、適宜設定可能であるが、当該被係止部は、前記押圧部の先端から前記押圧操作方向と直交する方向に突出して前記接触部の一部を構成することが、より好ましい。このように被係止部が押圧部の先端とともに接触部の一部を構成することは、当該押圧部の断面積を増やすことなく接触部の面積（すなわち操作部材とスイッチ素子との接触面積）を十分に確保することを可能にする。 The position where the locked portion protrudes from the pressing portion can be set as appropriate, but the locked portion protrudes from the tip of the pressing portion in a direction perpendicular to the pressing operation direction, and the position of the contact portion. It is more preferable to constitute a part. In this way, the locked portion constitutes a part of the contact portion together with the tip of the pressing portion, so that the area of the contact portion (that is, the contact area between the operation member and the switch element) is increased without increasing the cross-sectional area of the pressing portion. Can be secured sufficiently.
　本発明に係る操作装置は、前記操作部材として複数の操作部材を含んでもよい。その場合、前記保持部材の保持部が前記操作部材をそれぞれ保持し、当該保持部材は各操作部材の被係止部をそれぞれ係止する複数の撓み片を有すればよい。この装置によれば、各操作部材についてその押圧部および被係止部の位置が共通化されるため、装置全体の構造の簡素化及び小型化がより著しいものとなる。 The operating device according to the present invention may include a plurality of operating members as the operating member. In that case, the holding part of the holding member may hold the operation member, and the holding member may have a plurality of bending pieces that respectively lock the locked parts of the operation members. According to this device, since the positions of the pressing portion and the locked portion are made common to each operation member, the simplification and downsizing of the structure of the entire device become more remarkable.
　また本発明は、前記の操作装置と、この操作装置において押圧操作される操作部材の押圧部により押圧されるスイッチ素子とを備えたスイッチ装置を提供する。このスイッチ装置におけるスイッチ素子は、前記押圧部により押圧された時に当該押圧部に押圧操作方向と反対方向の反力を与えるものであり、かつ、その反力によって前記操作部材の被係止部を前記係止部に押付ける位置に設けられる。 The present invention also provides a switch device comprising the above-described operation device and a switch element that is pressed by a pressing portion of an operation member that is pressed by the operation device. The switch element in the switch device gives a reaction force in a direction opposite to the pressing operation direction to the pressing portion when pressed by the pressing portion, and the locked portion of the operation member is moved by the reaction force. It is provided at a position to be pressed against the locking portion.
