發展’因此在多方向輸入裝置中亦要求能由一個操作體進 打多種操作如此的構成。但是，上述現有的多方向輸入裝 置中’藉由開關元件3只能檢測按壓操作體4的傾倒方向， 而傾倒方向的細分化成爲誤動作的要因，因此，必然地不 能增加太多操作内容的種類。 即’現有的多方向輸入裝置中，只能檢測按壓操作體4 向哪個方向傾倒操作，而如果能判定例如按壓操作體4是淺 度（弱）傾倒操作還是深度（強）傾倒操作，則與只檢測傾倒方 向的情形相比，更能使可檢測的操作内容的種類倍增。其 結果是，可以獲得能使游標的移動速度或地圖資訊的倍率 等發生變化的多功能多方向輸入裝置。 【發明内容】 本發明即是鑒於此種現有技術的現狀而産生者，其目的 98323.doc 200531106 ，在於提供-種不僅能檢測傾倒操作時傾倒方向，還能檢測 傾倒角度大小的多方向輸入裝置。 爲了實現上述目的，本發明的多方向輪入裝置，具備配 置在大致同一圓周上的多個檢測元件、以距這些檢測元件 大致等距離的位置爲擺動中心而能傾倒的操作體、夹設在 上述各檢測元件與上述操作體之間的多個按屢突起’ ·上述 m件，係將至少任意一方設置在可青曲板片上的電阻 圖案與電極圖案隔著間隙而可以接觸或分離地相對配置而 構成者；並且上述按麼突起係配置在上述可彎曲板片上且 由對應上述操作體的傾倒量而變化形狀的彈性材料所形

=電阻值降低，而不位於操作體傾倒方向上的檢測元件其 電阻圖案和電極圖案分離，因此該電阻圖案 :： 值爲最大。 弘阻 並且，對操作體向規定方向傾倒方向傾倒操作時，若其 傾倒方向小’則按壓突起對可彎曲板片的按壓面積小，因 此°亥可彎曲板片局部彎曲，從而，電阻圖案與電極圖案 9B323.doc 200531106 的接觸面積小，該電阻圖案兩端間的電阻值的降低較小。 然而，若操作體的傾倒角度大，則按壓突起由於壓屈等而 發生較大彈性變形，因此，對可彎曲板片#按廢面積大， 該可彎曲板片在稍寬的區域發生彎曲，從而電阻圖案和電 極圖木的接觸面積增大，該電阻圖案兩端間的電阻值的降 低較大。因此，藉由測定電阻圖案兩端間的電壓等作爲檢 測元件的輸出i，不<堇能檢測操作體的傾倒方肖，還能檢 測傾倒角度的大小。 上述構成中，具備將上述操作體支撐爲中立狀態的彈性 ^樓構件^在該彈性支撐構件上—體形成上述多個按壓 犬起，則彈性支撐構件可作爲使傾倒狀態的操作體向中立 狀態自動重設的重設裝置而發揮作用，該彈性構件和多個 按壓突起爲一體形成品，因此部件件數少，為較佳者。另 外，此種情況下，若具備收納上述彈性支撐構件並使上述 操：體的操作部從上部開口突出的殼體，在該殼體内底面 上叹置上述多個檢測元件’並且，以彈性支撐構件作爲隔

二：長邊方向且石该切線方向的剖面爲大致V字形或大致u 字幵V的中空形&，因Λ不需使多個檢測元件和多個按壓突 起等的配置空間大徑化，且能使操作體進行深度（強）傾倒操 作時按壓突起料彎曲板片的按壓面積顯著增大，因此容 易進行小型化、亦能謀求可靠性的提升。 卜上述構成中，若在上述可彎曲板片上設置狹縫， 將上述按壓突起配置在上述可彎曲板片的上述狹縫附近， 谷易使可壽曲板片在狹縫附近彎曲，因此為較佳者。 [發明之效果] 本發明的多方向輸入裝置，按壓突起相對可彎曲板片的 铋壓面積對應於操作體傾倒角度的大小而增減，且隨之使 可4曲板片的言曲區域發生變化，從而增減電阻圖案和電 極圖案的接觸面積，因此根據各檢測元件的輸出值，不僅 能檢測操作體的傾倒方向，還能檢測傾倒角度的大小。即， 不僅能檢測按壓操作體向哪個方向傾倒操作，還能檢測按 壓操作體是淺度（弱）傾倒操作還是深度（強）傾倒操作，因 98323.doc -10- 200531106 此，能由一個操作體簡單且準確地進行多種操作，能實現 多功能多方向輸入裝置。 【實施方式】 以下，參照附圖對本發明的實施方式進行說明，圖丨係本 發明的第1實施例的多方向輸入裝置的分解立體圖，圖2係 表不構成該輸入裝置的附有按壓突起的彈性支撐構件的底 面形狀的立體圖，圖3係構成該輸入裝置的物性電路基板的

被支撐的操作體15、在底面4處突出設置有按壓突起μ的彈 性支撐構件17、從折疊形狀的層疊部18a延伸出帶狀延伸部 18b的韌性電路基板18。該多方向輸入裝置1〇中，操作體Η 的操作鈕（操作部）15a以外的部分、包含按壓突起16的彈性 支撐構件17、和韌性電路基板18的層疊部18a被收納在殼體 U内部，層疊部18a中的與各按壓突起16相對的4處作爲檢 測元件而發揮作用。 對各部分的詳細構成進行說明，蓋構件12爲具有中心孔 12a和一相對外突片i2b的大致圓板狀構件，墊圈13爲具有 98323.doc 200531106 一相對外突起13a的環狀構件。蓋構件12經由彈性支撐部17 的凸緣部17a搭載在墊圈13上。框狀外殼14具有設置韌性電 路基板18的層疊部18a的底板部14a、包圍塾圈13的環狀壁 14b、和配置蓋構件12的上部開口 14c，設置在環狀壁14b上 的一對凹狀切口 14d内插入有向外突片12b和向外突起 13a，從而能使蓋構件12和墊圈π相對框狀外殼14進行定 位。在框狀外殼14的上部開口 14c周圍突出設置多個卡扣片 14e，將這些卡扣片14e向内方彎折，從而鉚接固定蓋構件 12 ° 操作體15的中心部形成向上延伸的操作鈕丨5a，該操作鈕 15 a貝通盖構件12的中心孔12a向上方突出。另外，操作體 15的中心部形成向下延伸的支軸151)，該支軸151)搭載在韌 性電路基板18的層疊部18a上。操作體15的外周緣部被彈性 支擇構件17在直徑方向上限制位置，因此，操作體15的擺 動中心爲位於彈性支撐構件1 7中心線上的支軸15b的前端 部。 彈性支撐構件17由橡膠等彈性材料形成，各按壓突起i 6 與彈性支撐構件17 —體形成。在彈性支撐構件丨7的中心部 向下突出設置圓筒部17b，該圓筒部17b内插入操作體15的 支軸15b。在彈性支撐構件π的外周部形成具有一對卡扣片 1 7c的環狀凸緣部17a ’將各卡扣片丨7c插入框狀外殼丨4的凹 狀切口 14d内，以蓋構件12和墊圈13夾持凸緣部17a，從而 彈性支撐構件17的外周部被固定在定位狀態。並且，以該 彈性支撐構件17爲隔間壁，殼體丨丨的内部空間被分離成上 98323.doc -12- 200531106 4開口 14c側的空間和層疊部i 側的空間，因此，即使從 中匕孔12afe入塵埃等，亦不會對檢測元件造成不良影響 (參照圖5)。該彈性支撐構件Π，將操作體I5支撐在中立狀 心同呀在刼作體15傾倒操作時可彈性變形（參照圖6)。 在彈性支撐構件丨7底面向下突出設置的4個按壓突起 16形成在大致同一圓周上的各間隔90度的等間隔的位 置。如圖2所示，這些按壓突起16爲相同形狀、均被形成大 致圓錐形的中空形狀，而若操作體15向任意按壓突起⑹斤 處的方向進行較大傾倒操作，則如圖6所示，位於其方向上 的按壓突起關屈而發生較大彈性變形。但是，在操作體 15傾倒角度小時，按壓突起16不會壓屈。 在韌性電路基板18上，如圖3的展開圖所示，形成由碳等 構成的電阻圖案19及保護電阻圖案2〇、由銀等構成的電極 圖案2丨、與各圖案19、2〇連接且被導出的導線圖案22、在 延伸部18b端部露出的端子部23。該韌性電路基板“的層疊 部18a包含以折疊狀態位於上方的上部板片18〇和位於下= 的下部板片18d，兩板片18c、184由彎折部18e橋接。另外， 在構成層4:部18a的上部板片i8c和下部板片18d之間，夹設 有圖4所示的墊片24。對層疊部18a進行詳細說明，在上部 板片18c下表面等間隔地形成4個電極圖案21，同時在適當 處形成保護電阻圖案20。在下部板片18d上表面，等間隔地 形成4個電阻圖案19。墊片24上等間隔地形成4個窗孔24〇 這些電極圖案2卜電阻圖案19和窗孔24a三者被配置在相互 對應的位置，因此，層疊部！ 8a的各電極圖案2工隔著各窗孔 98323.doc -13 - 200531106 24a而與各電阻圖案19相對。 並且，在層疊部18a上的與各電極圖案2丨相對應的位置分 別配置按壓突起16，因此，若操作體15被傾倒操作，則位 於其方向上的按壓突起16下按下方的上部板片18c使其彎 曲，形成在彎曲區域的電極圖案21與相對的電阻圖案19接 觸。但是，按壓突起16對上部板片18c的按壓面積隨著該按 壓突起16是否壓屈而不同，因此，電極圖案21與電阻圖案 19的接觸面積對應於操作體15的傾倒量而不同。因此，藉 由對該接觸面積的不同進行電檢測，從而能檢測操作體15 的傾倒角度的大小。即，韌性電路基板18的層疊部18a，能 使與4個按壓突起16相對的4處作爲檢測操作體15的傾倒方 向及傾倒量的檢測元件而發揮作用。 接著，對如此構成的多方向輸入裝置丨〇的工作進行說 明，如圖5所示，在不操作時，操作體15由彈性支撐構件^ 保持在不傾斜的中立狀態，各按壓突起16不會壓彎上部板 片18cm載在層疊部18a上。因此，如圖7實線所示那 樣’各電極圖案2 1均離開相對的電阻圖案i 9，從而各電阻 圖案19兩端間的電阻值爲最大。 在4狀恕，若操作者按壓操作操作鈕1，彈性支撐構件 17發生彈性變形使操作體15傾倒，則由位於傾倒方向上的 按壓=起16壓彎上部板片18e，因此，位於該按壓突起^下 方的電極圖案21與相對的電阻圖案19接觸，該電阻圖案D 兩端間^電阻值降低。因此，藉由與端子部23連接的外部 "、〗疋各电阻圖案19兩端間的電壓等，可檢測哪個電阻 98323.doc -14- 200531106 圖案19兩端間的電阻值降低 15的傾倒方向。 從而能判定操作時的操作體 另外’該多方向輸入裝置10’如上所述還能檢測操作體 ㈣傾倒角度的大小。即’若操作體15向規定方向傾倒操 作％，操作力㈣、操作體15的傾倒角度^、，按麼突起邮

大、亥電阻圖案19兩端間的電阻值的降低較大。此時，若 除去對操作體15的操作力，則彈性支援構件17及按壓突起 依靠自身的彈性回到原來的形狀，因此，操作心從深 度傾倒狀怨自動重設成原來的中立狀態。 如此，本實施例的多方向輸入裝置1〇，其構成是對應於 98323.doc 15 200531106 操作體15的傾倒量，電極圖案21和電阻圖案19的接觸面積

構件12和墊圈13及框狀外殼14形成的殼體u、可以傾倒地 被支撐的操作體15、在底面4處突出設置有按壓突起16的彈 性支撐構件17、在下部基板19上層疊上部基板2〇而形成爲 層璺部1 8a的韌性電路基板丨8和在圓碗頂部（圓弧狀頂 部）21a上搭載操作體15且擺動自由地支撐其的支柱21。該 多方向輸入裝置ίο，操作體15的除了操作鈕（操作部）l5a以 外的部分、包含按壓突起16的彈性支撐構件17、韌性電路 基板18的層疊部18a的大部分和支柱21的大部分被收納在 殼體11内部，層疊部18a中的與各按壓突起16相對的4處作 爲檢測元件發揮作用。 關於各部分的詳細構成進行說明，蓋構件12爲具有中心 孔12a和一相對外突片12b的大致圓板狀構件，墊圈13爲具 有一相對外突起13a的環狀構件。蓋構件12經由彈性支撐部 17的凸緣部17a搭載在墊圈13上。框狀外殼14具有設置韌性 電路基板18的層登部18a的底板部1、包圍塾圈13的環狀 壁14b和配置蓋構件12的上部開口丨4C，設置在環狀壁i仆上 98323.doc -17- 200531106 的一對凹狀切口 14d内插入有向外突片12b和向外突起 13a ’從而能使蓋構件12和墊圈13相對框狀外殼14進行定 位。在框狀外殼14的上部開口 14C周圍突出設置多個卡扣片 14e，將這些卡扣片I4e向内方彎折，從而緊固蓋構件12。 另外’在框狀外殼14的底板部14a的中央部形成配合孔 14f ’將支柱2 1下端部壓入該配合孔14f中，從而支柱21豎立 設置在底板14a上。 在操作體15上突出設置操作鈕15a，該操作鈕i5a從拱形 狀的外突部15b中心部向上延伸。該外突部15b搭載在支柱 21的圓碗頂部21a上，因此，藉由使外突部15b在圓碗頂部 2la上滑動，從而，操作體15向任意方向可以傾倒（可以擺 動）。但是，操作體15的外周緣部被彈性支撐構件17在直徑 方向上限制位置，因此，操作體15的擺動中心被設定在彈 性支撐構件17的中心線上。還有，操作體15的操作鈕15&貫 通蓋構件12的中心孔12 a向上方突出。 彈性支撐構件17由橡膠等彈性材料形成，各按壓突起16 與彈性支撐構件17—體形成。在彈性支撐構件17的中心部 向下突出設置圓筒部丨7b，該圓筒部i 7b内貫穿插入支柱 21。在彈性支撐構件17的外周部形成具有一對卡扣片pc的 %狀凸緣部17a，將各卡扣片17c插入框狀外殼14的凹狀切 口 14d内，以蓋構件12和墊圈13夾持凸緣部17&，從而彈性 支撐構件17的外周部被固定在定位狀態。並且，以該彈性 支撐構件17爲隔間^，殼體u的内部空間被分離成上部開 口 14c側的空間和層疊部18a側的空間，因此，即使從中心 98323.doc -18- 200531106 孔12a侵入塵埃等，亦不會對檢測元件造成不良影響（參照 圖1 8)。5亥彈性支樓構件1 7，將操作體15支標在中立狀態， 同時在操作體15傾倒操作時可彈性變形（參照圖丨9)。 在彈性支撐構件17底面向下突出設置的4個按壓突起 16，形成在大致同一圓周上的各間隔9〇度的等間隔的位 置。如圖12及圖13所示，這些按壓突起16，爲同形狀，均 形成以上述圓周的切線方向爲長邊方向、沿該切線方向的 剖面爲大致v字形的中空形狀。並且若操作體15向任意按壓 突起16所處的方向進行較大傾倒操作，則如圖19所示，位 於其方向上的按壓突起16壓屈而發生較大彈性變形。但 是，在操作體15傾倒角度小時，按壓突起16不會壓屈。 在初性電路基板18的下部基板19上，設有向殼體11外方 大出的帶狀延伸部19a。如圖17所示，該下部基板丨9，在可 彎曲板片的一面上配置有由碳等構成的4個電阻圖案22、由 各電阻圖案22導出的導線圖案23和從延伸部19a端部露出 的端子部24。另外，如圖16所示，韌性電路基板丨8的上部 基板20，在可彎曲板片的一面上配置有由銀等構成的4個電 極圖案25。該上部基板20上夾著各電極圖案25形成由向各 私極圖案25長邊方向延伸的總共8條切入而成的狹縫26。各 电阻圖案22形成在大致同一圓周上的各間隔9〇度的等間隔 的位置，在與各電阻圖案22相對的位置分別形成電極圖案 25。另外，沒有圖示，但是，在上部基板19與上部基板2〇 的相對面上，在除了電阻圖案22和電極圖案25以外的區域 上开/成厚膜的抗钱劑層，以這些抗I虫劑層作爲塾片，各電 98323.doc -19- 200531106

Therefore, the convex portions 3 and 3 are disengaged, so that all the switching elements 3 remain OFF. If the operator presses down on the upper surface of the operating body 4 in an area corresponding to any of 98323.doc 200531106, the thin-walled portion 5 near the convex portion 4a is crushed and the pressing operating body 4 falls down. The convex portion 4a is pressed and driven to switch the switching element 3 opposite to 0FF to ON. Therefore, by detecting which switching element 3 is ON and determining the tilting direction of the operating body 4 during operation, it is possible to output different control signals to external circuits corresponding to the plurality of tilting directions. In addition, if the operating force applied to the pressing operation body 4 is removed, the buckled thin-walled portion 5a returns to its original shape by its own elasticity. Therefore, the pressing operation body 4 is automatically reset from the dumped state to the original neutral state . Patent Document 1: JP-A-2001-184999 (Page 2, Figure 2) Problems to be solved by the invention However, recently, due to the development of multifunctionality and miniaturization of various electronic devices, it has been used in a multidirectional input device. It is also required to have a structure capable of performing multiple operations from one operating body. However, in the above-mentioned conventional multi-directional input device, 'the switch element 3 can only detect the dumping direction of the pressing operation body 4, and the subdivision of the dumping direction becomes a cause of malfunction. Therefore, it is unavoidable to add too many types of operation content. . That is, 'the existing multi-directional input device can only detect in which direction the pressing operation body 4 is dumped, and if it can be determined whether the pressing operation body 4 is a shallow (weak) dumping operation or a deep (strong) dumping operation, for example, Compared to the case where only the dumping direction is detected, the types of detectable operation contents can be doubled. As a result, it is possible to obtain a multifunctional multidirectional input device capable of changing the moving speed of a cursor, the magnification of map information, and the like. [Summary of the Invention] The present invention was created in view of the status quo of such prior art, and its purpose is 98323.doc 200531106, which is to provide a multi-directional input device that can detect not only the dumping direction during a dumping operation, but also the magnitude of the dumping angle. . In order to achieve the above object, the multi-directional wheel-in device of the present invention includes a plurality of detection elements arranged on substantially the same circumference, an operating body capable of being tilted with a position approximately equal to the distance from these detection elements as a swing center, and sandwiched between The multiple protrusions between each of the detection elements and the operating body are described above. The above-mentioned m pieces are arranged so that at least one of the resistance pattern and the electrode pattern on the bendable plate can be in contact with or separated from each other through a gap. The pressing protrusion is arranged on the bendable plate and is formed of an elastic material that changes shape according to the amount of the operating body toppling. The pressing protrusion corresponds to the area of the bend of the bendable plate. The amount of pouring of the above-mentioned body changes, and the contact area between the resistance pattern and the electrode pattern changes. The multi-directional input device configured in this manner can be driven by the operation body being dumped =, so that the detection element located in its direction is pressed and driven by the corresponding pressing protrusion, so that the dump #direction can be detected. The detection element located in the operation = dumping direction. The bendable plate is pushed in by the pressing protrusion. The barrier pattern is in contact with the electrode pattern. Between the two ends of the resistance pattern = the resistance value is reduced, and it is not in the operation body dumping direction. The detection element has a resistance pattern separated from an electrode pattern, so the resistance pattern :: value is the largest. In addition, when the operating body is tilted in a predetermined direction, if the tilting direction is small, the pressing area of the pressing protrusion on the bendable plate is small, so the bendable plate is partially bent, so that the resistance pattern and The contact area of the electrode pattern 9B323.doc 200531106 is small, and the decrease in the resistance value between the two ends of the resistance pattern is small. However, if the tilting angle of the operating body is large, the pressing protrusions undergo large elastic deformation due to buckling or the like. Therefore, the waste area of the bendable plate # is large, and the bendable plate is bent in a slightly wider area. As a result, the contact area between the resistance pattern and the electrode pattern is increased, and the resistance value between the two ends of the resistance pattern is greatly reduced. Therefore, by measuring the voltage between the two ends of the resistance pattern and the like as the output i of the detecting element, it is possible to detect the magnitude of the tilting angle without detecting the tilting angle of the operating body. In the above configuration, there is provided an elastic support member that supports the operation body in a neutral state. On the elastic support member, the plurality of pressing dogs are formed, and then the elastic support member can be used to neutralize the operation body in the dumped state. The automatic reset reset device functions. The elastic member and the plurality of pressing protrusions are integrally formed. Therefore, the number of parts is small, which is preferable. In addition, in this case, if a housing is provided that houses the elastic support member and the operation portion of the body protrudes from the upper opening, the plurality of detection elements are grouted on the bottom surface of the housing, and The support member serves as a partition wall to separate the internal space of the housing into the space on the upper opening side and the space on the detection element side. Even if dust or the like penetrates through the upper opening, there is no need to worry about adversely affecting the detection element. & can improve reliability. In the above configuration, any one of the electrode pattern and the resistance pattern is placed on the flexible plate that is driven by the pressing protrusion, but for the sake of high reliability and long life, It is preferable to provide an electrode pattern on the flexible plate. In this case, if the old plate 98323.doc 200531106 = Lu Chun's folded upper plate and the lower plate are joined via the cymbals, and a plurality of electrode patterns and a plurality of electrical patterns constituting each of the detection elements are simultaneously In the case where the blade u is on the lower surface of the upper plate and the upper surface of the lower plate, a plurality of detection elements are integrally formed with a simple structure, and therefore are preferred. In addition, in the above configuration, if both the resistance pattern and the electrode pattern are formed with a tangent direction of a circumference where the detection elements are arranged as a long side: direction shape, and the protrusions are formed in the tangential direction, two : The cross section in the long side direction and the tangential direction is a substantially V-shape or a substantially U-shape 幵 V & because Λ does not need to increase the space for disposing a plurality of detection elements and a plurality of pressing protrusions, and Since the pressing area of the pressing projection bending plate when the operating body is subjected to a deep (strong) dumping operation is remarkably increased, miniaturization is easy, and reliability can be improved. In the above configuration, if a slit is provided in the bendable plate, and the pressing protrusion is arranged near the slit of the bendable plate, Gu Yi bends the bendable bendable plate near the slit, so it is relatively easy. Best. [Effects of the Invention] In the multi-directional input device of the present invention, the bismuth pressure area of the pressing protrusion relative to the bendable plate increases or decreases according to the magnitude of the tilting angle of the operating body, and the speech area of the bendable plate is generated accordingly. The change increases the contact area between the resistance pattern and the electrode pattern. Therefore, according to the output value of each detection element, not only the tilting direction of the operating body but also the magnitude of the tilting angle can be detected. That is, it can detect not only the direction in which the pressing operation body is dumped, but also whether the pressing operation body is a shallow (weak) dumping operation or a deep (strong) dumping operation, because 98323.doc -10- 200531106 It can perform a variety of operations simply and accurately, and can realize a multifunctional and multi-directional input device. [Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 丨 is an exploded perspective view of the multi-directional input device according to the first embodiment of the present invention, and FIG. 2 is a diagram showing the input device with a pressing protrusion. 3 is a perspective view of the shape of the bottom surface of the elastic support member, FIG. 3 is an expanded view of a physical circuit board constituting the input device, FIG. 4 is a plan view of a gasket held by a folded portion of the flexible circuit board, and FIG. 5 is the input Sectional view when the device is not in operation, FIG. 6 is a cross-sectional view of the input device when the dumping amount is large, and FIG. 7 is a cross-sectional view of the main part of the pressing protrusion and the detection element when the input device is not in operation, and FIG. 1 is the input device. A cross-sectional view of the main part of the pressing protrusion and the detection element during a large dump operation. The multi-directional input device 10 shown in these figures is mainly composed of a housing u formed by a cover member 12 and a gasket 13 and a frame-shaped housing 14, an operating body 15 which can be tiltedly supported, and a protrusion provided on the bottom surface 4. A flexible circuit board 18 is provided with an elastic support member 17 that presses the protrusion μ, and a strip-shaped extension 18b extending from the folded-shaped laminated portion 18a. In this multi-directional input device 10, parts other than the operation knob (operation part) 15a of the operation body 、, the elastic support member 17 including the pressing protrusion 16 and the laminated portion 18a of the flexible circuit board 18 are housed inside the housing U The four positions in the laminated portion 18 a opposite to each of the pressing protrusions 16 function as detection elements. The detailed structure of each part will be described. The cover member 12 is a generally disc-shaped member having a central hole 12a and an opposite outer protruding piece i2b, and the washer 13 is a ring-shaped member having 98323.doc 200531106 an outward protruding 13a. The cover member 12 is mounted on the gasket 13 via the flange portion 17 a of the elastic support portion 17. The frame-shaped housing 14 has a bottom plate portion 14 a on which a laminated portion 18 a of the flexible circuit board 18 is provided, an annular wall 14 b surrounding the collar 13, and an upper opening 14 c on which the cover member 12 is arranged. An outwardly protruding piece 12b and an outwardly protruding 13a are inserted into the notch 14d, so that the cover member 12 and the gasket π can be positioned relative to the frame-shaped case 14. A plurality of buckle pieces 14e are protruded around the upper opening 14c of the frame-shaped casing 14, and the buckle pieces 14e are bent inward, so that the center part of the fixing cover member 12 ° is riveted to form an upwardly extending operation button. 5a, the center button 12a of the Beton cover member 12 of the operation button 15a protrudes upward. Further, a support shaft 151) extending downward is formed at the center portion of the operation body 15, and the support shaft 151) is mounted on the laminated portion 18a of the flexible circuit board 18. The outer peripheral edge portion of the operating body 15 is restricted in position in the diametrical direction by the elastic support member 17, so that the swing center of the operating body 15 is the front end portion of the support shaft 15b located on the center line of the elastic support member 17. The elastic supporting member 17 is formed of an elastic material such as rubber, and each pressing protrusion i 6 is formed integrally with the elastic supporting member 17. A cylindrical portion 17b is protruded downward from a center portion of the elastic support member 7 and a support shaft 15b of the operating body 15 is inserted into the cylindrical portion 17b. A ring-shaped flange portion 17a having a pair of buckle pieces 17c is formed on the outer peripheral portion of the elastic support member π. Each buckle piece 7c is inserted into a concave cutout 14d of the frame-shaped case 4 and the cover member 12 and The washer 13 sandwiches the flange portion 17a, so that the outer peripheral portion of the elastic support member 17 is fixed in the positioning state. In addition, with the elastic supporting member 17 as a partition wall, the internal space of the housing 丨 丨 is separated into the upper 9823.doc -12- 200531106 4 space on the side of the opening 14c and the space on the i side of the stacking portion. If the hole 12afe is exposed to dust or the like, it will not adversely affect the detection element (see FIG. 5). This elastic supporting member Π supports the operating body I5 in a neutral shape, and can be elastically deformed during the tilting operation of the operating body 15 (see Fig. 6). Four pressing protrusions 16 protruding downward from the bottom surface of the elastic supporting member 7 are formed at equal intervals at intervals of 90 degrees on the same circumference. As shown in FIG. 2, the pressing protrusions 16 have the same shape and are formed into a generally conical hollow shape. If the operating body 15 performs a large dumping operation in the direction of any pressing protrusion, as shown in FIG. 6. , The pressing protrusion located in its direction is closed and flexed, and a large elastic deformation occurs. However, when the tilt angle of the operating body 15 is small, the pressing protrusion 16 is not buckled. As shown in the expanded view of FIG. 3, a flexible circuit substrate 18 is formed with a resistance pattern 19 and a protective resistance pattern 20 made of carbon or the like, and an electrode pattern 2 made of silver or the like and connected to the respective patterns 19 and 20 The lead pattern 22 to be led out and the terminal portion 23 exposed at the end of the extension portion 18b. The laminated portion 18a of the flexible circuit board includes an upper plate 18o positioned above and a lower plate 18d positioned below, and the two plates 18c and 184 are bridged by the bent portion 18e. In addition, the constituent layer 4 : Between the upper plate i8c and the lower plate 18d of the portion 18a, a spacer 24 shown in Fig. 4 is sandwiched. The laminated portion 18a is described in detail, and four electrodes are formed at equal intervals on the lower surface of the upper plate 18c. At the same time, a protective resistor pattern 20 is formed at a suitable position at the same time. On the upper surface of the lower plate 18d, four resistance patterns 19 are formed at regular intervals. Four spacers 24 are formed at regular intervals on the gasket 24. These electrode patterns 2b The resistance pattern 19 and the window hole 24a are arranged at positions corresponding to each other. Therefore, the electrode pattern 2 of the 8a is opposed to each of the resistance patterns 19 via the window holes 98323.doc -13-200531106 24a. In addition, the pressing protrusions 16 are arranged at positions corresponding to the respective electrode patterns 2 丨 on the lamination portion 18a. Therefore, if the operating body 15 is tilted, the upper plate below the pressing protrusion 16 located in the direction is pressed. 18c make it bend, forming in the bend The area of the electrode pattern 21 is in contact with the opposite resistance pattern 19. However, the pressing area of the pressing protrusion 16 on the upper plate 18c varies depending on whether the pressing protrusion 16 is buckled. Therefore, the contact area of the electrode pattern 21 and the resistance pattern 19 It differs according to the amount of tilting of the operating body 15. Therefore, the magnitude of the tilting angle of the operating body 15 can be detected by electrically detecting the difference in the contact area. That is, the laminated portion 18a of the flexible circuit board 18 can make the The four positions opposite to the four pressing protrusions 16 function as detection elements for detecting the tilting direction and amount of the operating body 15. Next, the operation of the multi-directional input device thus configured will be described, as shown in FIG. When not in operation, the operating body 15 is maintained in a neutral state without being tilted by the elastic supporting member ^, and each of the pressing protrusions 16 does not bend the upper plate 18cm on the laminated portion 18a. Therefore, as shown by the solid line in FIG. In that way, each of the electrode patterns 21 is separated from the opposite resistance pattern i 9, so that the resistance value between the two ends of each resistance pattern 19 is the maximum. In 4 states, if the operator presses the operation button 1 The elastic support member 17 is elastically deformed to cause the operating body 15 to fall, and the upper plate 18e is bent by pressing in the pouring direction = 16. Therefore, the electrode pattern 21 located below the pressing protrusion ^ is in contact with the opposite resistance pattern 19 The resistance value between the two ends of the resistance pattern D is reduced. Therefore, it is possible to detect which resistance 98323.doc -14- 200531106 The resistance value between both ends of the pattern 19 is lowered by the dumping direction of 15. Therefore, the operating body at the time of operation can be determined. In addition, as described above, the "multi-directional input device 10" can also detect the tilting angle of the operating body. That is, if the operating body 15 is tilted in the predetermined direction, the operating force is ㈣, the tilting angle of the operating body 15 is ^, the protrusion is bent, and the upper plate 18c is bent. In this way, the shallow dumping of the operating body 15 is known as shown by the two-dot chain line in FIG. The contact area between the electrode pattern 21 and the resistance pattern 19 below the shift protrusion 16 is small, and the reduction in resistance between the two ends of the resistance pattern 19 is small. At this time ', if the operating force on the operating body 15 is removed, the elastic support member 17 returns to its original shape based on the elasticity of the self-restraint, and is automatically reset to the original neutral state due to the operation of Λ' from a shallow dump. * In contrast to this, if the operating force is strong, the operating body. The tilting angle is large, and the pressing is done firmly. As shown in FIG. 6, the pressing protrusion 16 with an increased bottom area bends the upper plate 18c. In this way, when the operation ㈣ performs the depth ⑻ dumping operation, as shown in FIG. 8, the pressing area of the pressing protrusion 16 on the upper plate is increased. The contact area between the lower electrode pattern 21 and the resistance pattern 19 increases, and the resistance value between the two ends of the resistance pattern 19 decreases greatly. At this time, if the operating force on the operating body 15 is removed, the elastic supporting member 17 and the pressing protrusion return to their original shapes by their own elasticity, and therefore the operating center is automatically reset to its original neutral state from a deep dumping. In this way, the multi-directional input device 10 of this embodiment is structured to correspond to the dumping amount of the 98323.doc 15 200531106 operating body 15, and the contact area between the electrode pattern 21 and the resistance pattern 19 is reduced. The 23-connected external circuit measures the voltage between the two ends of each resistance pattern 19, and can detect which resistance map ㈣ how much the resistance value decreases, so that it can determine not only the tilting direction of the operating body 15, but also the magnitude of the dumping angle. . That is, a single operation body can perform a variety of operations individually and accurately. Therefore, the multi-directional input device 10 can be multifunctional. In this example, a resistor pattern 19 is provided on the lower plate 18d side, and an electrode pattern 设置 is provided on the upper plate 18e side of the pressed protrusion 16M, f. However, even if the configuration is the opposite, it can be the same jobs. However, such a configuration as in this embodiment can be expected to have high reliability and long life, and is therefore preferred.

In addition, the structure is provided with a pillar at the central portion of the bottom plate portion 14 & of the setting body 11, and the supporting body 15 omitting the support shaft 15b is swingably supported by the pillar, and the detection element can be driven by pressing. The pressing protrusions 16 are converted into other shapes to promote miniaturization. The multi-directional input device 10 shown in these figures is mainly composed of a housing u formed by a cover member 12 and a washer 13 and a frame-like housing 14, an operating body 15 which can be tiltedly supported, and a protrusion on the bottom surface 4 An elastic supporting member 17 provided with a pressing protrusion 16, a flexible circuit substrate 丨 8 formed by stacking an upper substrate 20 on a lower substrate 19 to form a layer portion 18 a 8, and mounting operations on a round bowl top (arc-shaped top) 21 a The body 15 swings and supports the pillar 21 freely. This multi-directional input device includes a portion of the operating body 15 other than the operation button (operation portion) 15a, an elastic support member 17 including a pressing protrusion 16, a large portion of the laminated portion 18a of the flexible circuit board 18, and a large portion of the pillar 21. It is housed inside the housing 11, and four places in the laminated portion 18 a opposite to each of the pressing protrusions 16 function as detection elements. The detailed structure of each part will be described. The cover member 12 is a substantially disc-shaped member having a central hole 12a and an opposite outer protruding piece 12b, and the washer 13 is a ring-shaped member having an opposite outer protrusion 13a. The cover member 12 is mounted on the gasket 13 via the flange portion 17a of the elastic support portion 17. The frame-like housing 14 has a bottom plate portion 18a of a layered portion 18a provided with a flexible circuit board 18. An annular wall 14b surrounding the ring 13 and an upper opening of the cover member 12 are provided on the annular wall i servant 98323. doc -17- 200531106 has a pair of concave cutouts 14d having outward protruding pieces 12b and outward protrusions 13a ′ inserted therein, so that the cover member 12 and the gasket 13 can be positioned relative to the frame-like casing 14. A plurality of clip pieces 14e are protruded around the upper opening 14C of the frame-shaped casing 14, and the clip pieces I4e are bent inward to fasten the cover member 12. In addition, a fitting hole 14f is formed in the central portion of the bottom plate portion 14a of the frame-shaped casing 14, and the lower end portion of the pillar 21 is pressed into the fitting hole 14f, so that the pillar 21 is erected on the bottom plate 14a. An operation button 15a is protrusively provided on the operation body 15, and the operation button i5a extends upward from the central portion of the arch-shaped outer protrusion 15b. The projecting portion 15b is mounted on the top portion 21a of the round bowl of the pillar 21. Therefore, by sliding the projecting portion 15b on the top portion 2la of the round bowl, the operating body 15 can be tilted (swingable) in any direction. However, since the outer peripheral edge portion of the operating body 15 is restricted in position in the diameter direction by the elastic support member 17, the swing center of the operating body 15 is set on the center line of the elastic support member 17. In addition, the operation button 15 of the operation body 15 penetrates the center hole 12a of the cover member 12 upward. The elastic support member 17 is formed of an elastic material such as rubber, and each of the pressing protrusions 16 and the elastic support member 17 are integrally formed. A cylindrical portion 丨 7b is protruded downward from a center portion of the elastic support member 17, and the cylindrical portion i 7b penetrates and inserts the stay 21 therein. A% -shaped flange portion 17 a having a pair of buckle pieces pc is formed on the outer peripheral portion of the elastic support member 17, and each buckle piece 17 c is inserted into the recessed cutout 14 d of the frame-shaped case 14, and is sandwiched between the cover member 12 and the washer 13. By holding the flange portion 17 &, the outer peripheral portion of the elastic support member 17 is fixed in the positioning state. Moreover, with the elastic support member 17 as a compartment ^, the internal space of the housing u is separated into a space on the upper opening 14c side and a space on the lamination portion 18a side, so even from the center 98323.doc -18- 200531106 hole 12a Intrusion of dust and the like will not adversely affect the detection element (see Figure 18). The elastic support member 17 of the Haihai Bridge 17 sets the operating body 15 in a neutral state, and can be elastically deformed when the operating body 15 is tilted (see FIG. 9). Four pressing protrusions 16 protruding downward from the bottom surface of the elastic supporting member 17 are formed at equally spaced positions at intervals of 90 degrees on the same circumference. As shown in Figs. 12 and 13, these pressing protrusions 16 have the same shape, and each has a hollow shape in which the tangential direction of the circumference is the long side direction and the cross section along the tangential direction is a substantially V-shape. Further, if the operating body 15 performs a large tilting operation in a direction in which the pressing protrusion 16 is located, as shown in FIG. 19, the pressing protrusion 16 located in the direction is buckled and elastically deformed. However, when the tilt angle of the operating body 15 is small, the pressing protrusion 16 does not buckle. The lower substrate 19 of the primary circuit board 18 is provided with a band-shaped extension 19a which is large outwardly of the case 11. As shown in FIG. 17, the lower substrate 9 is provided with four resistance patterns 22 made of carbon or the like on one side of the flexible plate, a lead pattern 23 derived from each resistance pattern 22, and an end portion from the extension 19a. Exposed terminal portion 24. In addition, as shown in Fig. 16, the upper substrate 20 of the flexible circuit board 8 is provided with four electrode patterns 25 made of silver or the like on one surface of the flexible plate. Each of the electrode patterns 25 is formed on the upper substrate 20 to form slits 26 formed by cutting into a total of eight extending in the longitudinal direction of each of the private electrode patterns 25. Each of the resistance patterns 22 is formed at regular intervals at intervals of 90 degrees on the same circumference, and electrode patterns 25 are formed at positions opposite to each of the resistance patterns 22. In addition, not shown, however, on the opposing surfaces of the upper substrate 19 and the upper substrate 20, a thick film anti-money agent layer is formed / formed on a region other than the resistance pattern 22 and the electrode pattern 25. The insecticide layer serves as a septum, and each of the electrode patterns 98323.doc -19-200531106 and the resistance pattern 22 can be in contact with and separated from each other. In addition, the pressing protrusions 16 are respectively disposed at positions corresponding to the respective electrode patterns 25 on the layer portion 18a. Therefore, when the operation body 15 is tilted, the pressing protrusions 16 located in the direction press the upper substrate 2 below. Then, the electrode pattern 25 formed in the curved region is brought into contact with the opposing resistance pattern 22. That is, the upper substrate 20 below the pressing protrusion 16 becomes a region where the electrode pattern 25 is formed, and this region is easily bent by being sandwiched between the two slits 26. Therefore, if a tilting operation force is applied to any of the pressing protrusions 16, The upper substrate 20 is bent under the lower portion, so that the electrode pattern 25 and the resistance pattern 22 can be brought into contact. However, the pressing area of the pressing substrate 16 on the upper substrate 20 differs depending on whether or not the pressing projection 16 is buckled. Therefore, the contact area between the electrode pattern 25 and the resistance pattern differs according to the amount of the operating body 15 toppling. Therefore, by detecting the difference in the contact area electrically, the magnitude of the tilting angle of the operating body 15 can be detected. In other words, the laminated portion of the movable circuit board 18 ... enables the four places where the four pressing protrusions 16 of the blood are opposed to each other to function as a detection element for detecting the pouring amount of the operating body 15 and the amount of the pouring. Next, the guardianship of the multi-directional input device (H) constructed in this way will be described at tf in FIG. 18. When not working, the operator will be maintained in a neutral state without tilt by the pillar η and the elastic support member 17. Each of the pressing protrusions 16 is not mounted on the upper substrate 20 ′ but is mounted on the laminated portion ⑽. Therefore, as shown in Figure 2 :, each electrode pattern 25 is separated from the opposite resistance pattern ㈣, so that the resistance value between the two ends of each pen resistance pattern 22 is maximum. In the δ-Hai-like sorrow, if you operate the old pine tired piece 17 on the strong strong secret iron, the female 1 will act as the operation button 15a, so that the elastic support structure " ^, and the operation body 15 is dumped, leaning in the direction of dumping 98323.doc -20 -The 200531106 fork C rises 16 and presses on the upper base plate 20 below it. In this way, the pressed area of the upper sigma substrate 20 pressed by the pressing protrusion I is sandwiched by two slits and is easily bent, so the upper substrate 20 is bent under the pressing protrusion 16, and here The formed electrode pattern 25 is in contact with the opposite resistance pattern 22, and the resistance value between both ends of the resistance pattern 22 decreases. Therefore, by measuring the electric dust between the two ends of each resistance pattern 22 with an external circuit connected to the terminal portion 24, the resistance value between the two ends of the resistance pattern 22 can be detected, so that the operation body 15 can be determined. Dump the direction. In addition, the above-mentioned "direction input device 10" can detect the magnitude of the tilting angle of the operating body. That is, if the operating body ^ $ is directed in a predetermined direction: when the operation is reversed, the operating force is weak and the tilting angle of the operating body 15), then the pressing force is large (16 does not buckle and bends the upper substrate 20). When the operation body b is dumped lightly (weakly), as shown by the two-dot chain line in FIG. 14, the pressing projection M has a small area by the upper substrate 20, so the upper substrate 2 () is partially bent and is located at The contact area between the electrode pattern and the resistor Qiu under the pressing protrusion 16 is small, and the resistance value between the two ends of the resistance pattern 22 is reduced. At this time, if the operating force on the operating body 15 is removed, the elastic support member leans against Its elasticity returns to its original shape. Therefore, the operating body i 5 is automatically reset to its original neutral state from a mildly dumped state. * In contrast, if the operating force is strong, the tilting angle of the operating body 15 is large, and the protrusion is pressed. As shown in FIG. 19 and FIG. 20, the pressing protrusion 16 with an increased bottom area bends the upper substrate 20. In this way, when the operation pad is deep (strong), the protrusion 16 is pressed during the dumping operation. The cymbal area of the upper substrate 2 () increases, so the upper substrate 20 It bends in a slightly wider area, so that the electrode pattern located below the pressing protrusion 98323.doc 21 200531106 16 increases the contact area with the resistance pattern 22, and the resistance value between the two ends of the resistance pattern 22 decreases greatly. If the operating force on the card body 5 is removed, the elastic supporting member 17 and the star-shaped protrusion μ return to their original shape by their own elasticity, so the operating body 15 is automatically reset from the state to the original neutral state. The multi-directional input device 10 of this embodiment has a configuration in which the contact area between the electrode pattern 25 and the resistance pattern 22 significantly changes according to the amount of material to be poured. “Therefore,” an external circuit connected to the terminal portion 24 is used. By measuring the electric quantity between the two ends of each resistance pattern 22, 'detecting which resistance map 多少 how much the resistance value between the two ends decreases,' it is possible to determine not only the dumping position of the operating body 15 but also the magnitude of the dumping angle. —One operating body 多种 Performs various operations early and accurately. Therefore, this multi-directional input device _ achieves multi-functionality. In addition, the multi-directional wheel-in device 10 is arranged on approximately the same circumference. Each of the resistance patterns 22 and each of the electrode patterns 25 are formed in a shape in which the tangent direction of the circumference is a long side direction, and the slits 26 are also formed in the tangential direction, and each of the pressing protrusions 16 is also formed in the tangential direction as The cross section in the longitudinal direction and the tangential direction is a substantially V-shaped hollow shape. Therefore, a large diameter such as a space for disposing the detection elements (resistance pattern 22 and electrode pattern 25, etc.) and a space for disposing the pressing protrusions 16 is not required. Therefore, it is easy to reduce the size of the entire device. In addition, when the operating body 15 is subjected to a deep (strong) tilting operation and the pressing protrusion is closed, the pressing protrusion can significantly increase the pressing area of the upper substrate 20, so that [Schematic description] 98323.doc -22- 200531106 • FIG. 1 is an exploded perspective view of a multi-directional input device according to a first embodiment of the present invention.
