【發明内容】 [發明所欲解決之問題] 然而，於上述先前之多方向輸入裝置中，因裝置本體落 下或踩踏而施加有如使操作體抵接於磁感測器般之強衝擊 時，磁感測器有破損之虞。尤其於磁感測器藉由焊錫固定 於可撓性基板之情形時，有該焊錫部分剝離之虞。 149980.doc -4- 201124885 [解決問題之技術手段] 本發明係鑒於此種實際情況而提出’其目的在於提供一 種磁感測器難以破損之多方向輸入裝置。 本發明之多方向輸入裝置之特徵在於包含：上殼體，其 設置有開口；下殼體’其配置於該上殼體之下方側且具有 底壁，操作體，其具有於上述上殼體與下殻體之間形成之 空洞部内滑動移動之移動部及露出於上述開口之操作部， 且保持有磁鐵；磁感測器，其與上述移動部相對向配置並 檢測上述磁鐵產生之磁場之變化；可撓性基板，其安裝有 上述磁感測器且配置於上述下殼體之底壁之下表面側·，以 及安裝構件，其配置於上述下殼體及可撓性基板之下方， 且包含將上述上殼體及下殼體—體化之金屬板；上述安裝 構件係包含與上述下殼體之底壁之下表面抵接之基部及連 .、。於β亥基。卩之彈性腕部，並藉由上述彈性腕部彈性地支持 上述可撓性基板中之至少上述磁感測器之安裝部。 」艮據上述多方向輸入裝置，由於可撓性基板中之磁感測 益之安裝部藉由安裳構件之彈性腕部進行彈性支持，故而 即便於，經由才木作體對磁感測器施#強衝擊之情升多時，亦可 藉由彈[生腕吸收s亥衝擊，因而能夠使磁感測器難以破 損。 於上述多方向輸入裝置中’較佳為上述磁感測器由樹脂 密封。於此情形時，由於能夠藉由樹脂來保護磁感測器， 故而能夠提高該磁感測器與可撓性基板之電連接之可靠 性0 149980.doc 201124885 t 於上述多方向輸入裝置中，較佳為上述彈性腕部與上述 基部連接設置，以自與上述可撓性基板之下表面相對向配 置之板狀部之外側向中央部延伸之方式相互對向地設置一 對，位於各自前端之自由端側對應於上述樹脂之^部分 配置。於此情料，由於在安裝構件之板㈣設置一對彈 性腕部且於彼等之自由端側支持可撓性基板，故而能夠彈 性支持可撓性基板之下表面之廣大面積。再者，由於在彈 性腕部之自由端側支持可撓性基板之磁感測器之安裝部， 故而即便於因樹脂（尤其熱硬化樹脂）之收縮而在可撓性基 板之下方側產生翹曲之情形時，亦可抑制該翹曲，從而能 夠確保磁感測器之檢測精度。 於上述多方向輸入裝置中，較佳為上述彈性腕部係藉由 如下而形成：於上述安裝構件之板狀部形成一對分離之第 一狹縫及將該等第一狹縫之中央部連結之第二狹縫，並且 於由上述第一狹縫及第·一狹縫界定之一對彈性片分別μ置 長孔。於此情形時，僅藉由於安裝構件之板狀部形成複數 個狹縫及長孔便能夠簡單地於安裝構件形成彈性腕部。 於上述多方向輸入裝置中’較佳為上述安裝構件之板狀 部與上述下殼體之底壁之間之間隙設定為大於上述可挽性 基板之板厚。於此情形時’由於利用安裝構件之板狀部與 下殼體之底壁之間之間隙能夠容易使可撓性基板彎曲，故 而能夠容易吸收施加給可撓性基板之衝擊，從而能夠使磁 感測器更難以破損。 於上述多方向輸入裝置中’較佳為上述可撓性基板係具 149980.doc 201124885 有橫越上述下殼體之底壁中央部之長條形狀，並且隔著上 述磁感測器沿長度方向形成一對安裝孔，藉由將設置於上 述下殼體之一對突起對應於上述一對安裝孔插通而將上述 可撓I1 生基板女·裝於έ亥下殼體，上述一對安裝孔之一者成為 於上述長度方向上較長之長孔。於此情形時，由於供設置 於下殼體之一對突起插通之一安裝孔形成為長孔，故而能 夠不費力地使可撓性基板於長度方向上彎曲，從而能夠容 易吸收施加給可撓性基板之衝擊。 於上述多方向輸入裝置中，較佳為於上述安裝構件設置 使上述安裝構件之板狀部朝比上述基部更下方側突出之一 對折t部，並且於位於上述一對折彎部之間之上述板狀部 與上述下殼體之底壁之間配設上述可撓性基板。於此情形 時，因設置使安裝構件之板狀部比基部更向下方側突出之 一對折彎部，且於位於一對折彎部之間之該板狀部與下殼 體之底壁之間配設可撓性基板，故而能夠提高安裝構件之 強度，且能夠藉由該安裝構件而於板狀部與下殼體之底壁 之間確保可撓性基板之收容區域。 [發明之效果] 根據本發明，因可撓性基板中之磁感測器之安裝部藉由 安裝構件之彈性腕部而彈性支持，故而即便於經由操作體 對磁感測器施加強衝擊之情形時，亦可藉由彈性腕部吸收 該衝擊，因而能夠使磁感測器難以破損。 【實施方式】 以下，參照附圖，詳細說明本發明之實施形態。本實施 149980.doc 201124885

部之空洞部中收納各種構成構件。於上殼體2及下殼體3重 合之狀態下，藉由使配置於多方向輸入裝置丨之下方側之 安裝構件4與上殼體2扣合結合而一體化。 上殼體2及下殼體3例如成形絕緣性之樹脂材料而形成。 上殼體2具有向下方側開口了之箱形&，於其上表面部η 之中央形成有圓形之開口部22…上殼體2具有自包含 平坦之板狀之壁部之上表面部21之四邊向下方側延伸之側 壁部23。、於該等側壁部23中，相對向之一對側壁部之 内壁構成平面部，且配置成相互平行。 149980.doc 201124885 下殼體3具有向上方側開口之箱形狀，於其作為底壁之 底面部31之中央設置有圓形之突出部32。該突出部32使下 殼體3之包含平坦之板狀之壁部之底面部31隆起而形成， 於該底面部3 1之背面（下表面）側設置有大致長圓形狀之凹 部33。於該突出部32之上表面形成有載置下述之保持構件 9之平面部32a。於底面部31之下表面即凹部33之側方側設 置用於保持下述之可撓性基板丨丨之一對突起34a、3仆。於 突起34a之周面设置有複數個肋，於被插通（壓入）至可撓 性基板11上所形成之孔i 14a中之狀態下固定可撓性基板 U。另一突起34b之前端部設置有稍大徑之卡止部，於插

且化圖1及圖2所示之左右方向延伸之板狀部43。該 板二部43之卞央部形成有沿圖1及圖2所示之左右方向延伸 之對彈性腕部44a、44b。上述彈性腕部44a、桃發揮自 下方側支持可撓性基板11之與磁感測器113相對應之下表 面部分夕从 ^ 乍用。再者，安裝構件4之構成將於以下進行敍 述〇 ^成於设體内之空洞部t收納有操作體5、限制構件 149980.doc 201124885 6、間隔構件7、永久磁鐵（以下’簡稱為「磁鐵」）8、保持 構件9及螺旋彈簧1〇 ^操作體5以使其一部分自上殼體2之 開口部22向上方側突出之狀態被收納。限制構件6配置於 下述之操作體5之凹部54及凹部55。保持構件9以在内部保 持有磁鐵8之狀態安裝在操作體5之下表面。螺旋彈菁1〇配 置於安裝在操作體5之保持構件9及下殼體3之突出部32之 外周側。間隔構件7插入配置於操作體5及限制構件6與螺 旋彈簧10之間。以下，說明各構成構件之構成。 操作體5具有：例如成形絕緣性之樹脂材料而形成，以 自上殼體2之開口部22向上方側突出之狀態露出之操作部 5 1 ;配置於殼體内之空洞部之移動部52 ;以及連結該等之 縮頸部53。操作部51及移動部52均具有圓盤形狀，縮頸部 53設置成比該等直徑小。再者，俯視觀察操作體5時，該 等操作部5 1、移動部52及縮頸部53形成為同心圓狀。操作 部51設為經由上殼體2之開口部22能夠插通至外部側之尺 寸，即，比開口部22直徑小，並由自開口部22露出之部分 接受來自操作者之滑動操作。移動部52與該操作部5〖一併 移動。於移動部52之下表面中央形成有沿多方向輸入裝置 1之圖3中之左右方向，即，限制構件6之長度方向呈帶狀 之一對凹部54。於該凹部54之中央形成有與移動部52成為 同心圓之圓形之凹部55。於該等凹部54及凹部55配置有限 制構件6。又，於凹部55配置有保持有磁鐵8之狀態之保持 構件9。 限制構件6例如由不鏽鋼等非磁性金屬材料形成，具有 149980.doc •10· 201124885 大致沿多方向輸入裝置1之圖3中之左右方向延伸之長條形 狀。限制構件6具有：具有與形成於操作體5之移動部52之 凹部54大致相同寬度之板狀部61 ;自該板狀部“之長度方 向即左右方向之兩端部向下方側折彎形成之一對限制片 62。該等限制片62以與上殼體2之側壁部23a之内壁面相對 向之方式平行配置。上述限制片62之外表面間之長度設置 為與上殼體2之側壁部23a之内壁面間之長度大致相同。再 者，若限制構件6由非磁性體構成，則不必一定由金屬材 料構成，例如’亦可由絕緣性之樹脂材料形成。 間隔構件7例如由薄板構件構成，㈣板構件由不錄鋼 等非磁性金屬材料形成並具有圓環形狀。於間隔構件7之 中央形成有圓形之開口部71，該開口部71之内徑設置為比 形成於操作體5之移動部52之凹部55之外徑略大之尺寸。 再者，如果間隔構件7由非磁性體構成，則不必一定由金 屬材料構成，例如，亦可由絕緣性之樹脂材料形成。 保持構件9例如成形絕緣性之樹脂材料而形成，並 大致向上方側開口 了之圓形形狀。該保持構件9係於移動 =了側之中央部構成與該移動部52成為同心圓狀而 體化之小徑。卜而且，保持構件9具有收納磁鐵8之圓形 ::納部91，該磁鐵8具有圓盤形狀’於保持構❺之内底 形成有矩形之開口部92ae該開口部％係用於積存磨 貝粉而形成’該磨損粉係因保持構件9與突出部η 隨著操作體5之滑動移動而進行滑動接觸所產生。藉 由如此形成開口部仏’能夠有效地防止由上述磨損粉： 149980.doc 201124885 起之不穩疋之操作體5之滑動移動。又，於設置於收納部 91周圍之包含圓弧狀（圓環狀）之壁部之側壁部％形成有以 收容了限制構件6之板狀部61之一部分之狀態使該板狀部 61插通之一對切口部93^為了使板狀部61插通，該切口 部93a之寬度尺寸設定為比該板狀部61之寬度寬。而且， 切口部93a之深度尺寸比板狀部61之板厚略大。 螺旋彈簧10例如由不鏽鋼等非磁性金屬材料形成。於螺 旋彈簣10中，在特定長度之柱狀螺旋彈簧之兩端設置未圖 示之鉤部等，藉由連結其兩端（鉤部）而將其形成為環狀。 於該螺旋彈簧10未伸長之狀態（無負載狀態）下，其内徑設 置成比下殼體3之突出部32及保持構件9之外徑略小之尺 寸。該螺旋彈簧10係將於操作體5進行滑動移動時使操作 體5復位到初始位置之彈性力施加給固定於操作體5上之保 持構件9之構件。 下设體3之下表面安裝有可撓性基板丨丨，該可撓性基板 11安裝檢測操作體5之滑動移動之下述之磁感測器113。該 可撓性基板11例如由聚醯亞胺樹脂薄膜等絕緣性樹脂薄膜 構成’且其表面形成有金屬配線等導電圖案。該可撓性基 板11以將磁感測器113配置於與下殼體3之凹部33相對應之 位置之方式安裝於下殼體3。再者，於可撓性基板^中， 例如在就謨有焊線或焊錫等將磁感測器U3之未圖示之電 極部焊接於可撓性基板11之金屬配線上後，為了防止其構 成構件之腐蝕或檢測精度之劣化，而藉由例如由絕緣性之 熱硬化樹脂材料等形成之密封部111進行密封。如此，藉 149980.doc 12 201124885 由利用密封部111密封磁感測器113，能夠利用樹脂保護磁 感測器113及焊接部，因此即便於對可撓性基板u施加衝 擊之情形時，亦可確保磁感測器113與可撓性基板丨丨之電 連接部分之導通。 下殼體3之凹部33收容該密封部111。又，於可撓性基板 11上設置有與輸出端子連接之包含導電圖案之多根導線 Π2 ’該輸出端子將來自構成磁感測器113之磁檢測元件之 信號向外部輸出。進而，於可撓性基板丨丨上隔著密封部 hi設置有一對孔，即，圓形之孔U4a、長孔U4b。該等 圓孔114a、長孔丨14b中分別插通有設置於下殼體3之下表 面之一對突起34a、34b。再者，關於安裝於該可撓性基板 11上之磁感測器11 3，將於以下進行敍述。 若組裝具有如此構成之多方向輸入裝置1，則如圖3所 示，操作體5之操作部51成為向上殼體2之上方側突出之狀 態。於多方向輸入裝置1之内部，如圖4及圖5所示在下 殼體3之突出部32之平面部仏之上方載置有保持了磁鐵8 之狀態之保持構件9。即，於操作體5未滑動移動之初始狀 2下，突出部32與保持構件9以兩者沿圖4等之上下方向重 合之方式相對向配置。螺旋彈黃1()以包圍㈣突出部Μ 保持構件9之周圍之方式在自無負載狀態略微伸長之狀離 :配置於下殼體3之底面部31上…，如圖4、圖5所 /呆作體5之移動部52及保持了磁鐵8之保持構件规由 —之底面#31'更具體而言經由突出部之平面部 仏而與磁感測器113在圖示上下方向相對向配置。 149980.doc 13 201124885 #作體5配置為，使操作部5ι向裝置外部突出，並且由 移動452限制螺旋彈黃1〇向上方側（操作體⑽）移動。即， 移動部52以離開下殼體3之底面部以狀態與底面部31大 致平行地相對向配i，螺旋彈簧1〇之上部，經由間隔構件7 又移動口P 52限制’下部受底面部3 1限制。而且，伴隨著操 作體5之⑺動移動，螺旋彈簧1〇在形成於下殼體3之底面部 31與移動部52(間隔構件7)之間之空間部内伸長變形。限制 構件6以收容於移動部52之下表面之—部分之狀態進行配 置，其限制片62以沿上殼體2之側壁部23a之内壁面具有微 J之間隙進行引導之方式相對向配置（參照圖4)。再者，此 時，限制片62之前端以不接觸到下殼體3之底面部^之方 式使兩者成為分離狀態。 間隔構件7配置於操作體5之移動部5 2及限制構件6之板 狀部與螺旋彈簧10之間。如此藉由於移動部似板狀部 61與螺旋彈簧10之間配置間隔構件7，即便在移動部52之 凹部54與限制構件6之間形成有間隙時，亦可由間隔構件7 防止螺旋彈簧10掛在或夾持於該間隙内之情況，因此即便 包含比較廉價之螺旋彈簧10作為彈性構件，亦不會損害裝 置之操作性。 〇 之操作體5、限制 圖6係表示本實施 此處，說明配置於殼體内之空洞部中 構件6、間隔構件7、保持構件9之關係。 形態之多方向輸入裝置丨具有之操作體5與限制構件6之關 係之立體圖》圖7係表示本實施形態之多方向輸入裝置1具 有之操作體5、限制構件6、間隔構件7、保持構件9之關^ 149980.doc -14- 201124885 之立體圖。圖8係圖7所示之操作體5及其周邊構件之側視 圖。 如圖6所示’限制構件6以跨越凹部55之方式配置於操作 體5之移動部52之下表面所形成之凹部54。如上述般，由 於限制構件6之板狀部61之寬度方向（γ方向）之寬度設置為 與凹部54之寬度大致相同（嚴格來說比凹部54之寬度略 窄）’因此板狀部61成為進入凹部54之狀態。另一方面， 限制構件6之限制片62以受上殼體2之側壁部23a之内壁面 限制之方式相對向配置。因此，對操作體5施加旋轉力 時，藉由使凹部54之側壁部54a與板狀部61之端面61&卡 合’並且使限制片62與側壁部23a之内壁面接觸，限制操 作體5之旋轉。 又，於限制構件6中，由於板狀部61收容於凹部54且其 限制片62與上殼體2之側壁部23a之内壁面相對向配置，故 而藉由側壁部23a，限制限制構件6向圖6所示之χ方向之滑 動移動，而容許向該圖所示之γ方向之移動。凹部54之側 壁部54a隔著移動部52之中央部以沿χ方向延伸之狀態沿該 圖所不之X方向形成於相對向之位置。再者，於操作體5向 圖6所不之Y方向滑動移動時，凹部54之側壁部54a與板狀 部61之端面61a卡合，從而操作體5與限制構件6一體進行 滑動移動。 保持構件9於收納部91收納了磁鐵8之狀態下，藉由黏結 劑等固定機構ID定於凹部55(參關7)。於此情形時，如圖 7所示，保持構件9以在其與操作體5之移動部“之間夾持 149980.doc 201124885 限制構件6之方式固定於凹部55。此時，限制構件6配置為 插通至移動部52與保持構件9之間。間隔構件7於使保持構 件9自開口部71向下方側突出之狀態下與操作體5之移動部 52及限制構件6之板狀部61相對向配置。 於以此方式固定之狀態下，如圖8所示，保持構件9成為 與操作體5 —體化之狀態。螺旋彈簧1〇配置於如此配置之 保持構件9及下殼體3之突出部32之外周側。在保持構件9 之内部收納有磁鐵8，且磁鐵8亦同樣地對應於操作體亏之 滑動移動而進行滑動移動。由此，保持構件亦為構成在上 殼體2與下殼體3之間之空洞部内滑動移動之設置於操作體 5之移動部之構件。安裝於上述可撓性基板^之磁感測器 113係藉由檢測由如此滑動移動之磁鐵8產生之磁場之變 化、具體而言磁通量之方向之變化來檢測操作體5之滑動 移動處之位置（滑動位置）。 此處，說明本實施形態之多方向輸入裝置1具有之可撓 性基板11上所安裝之磁感測器113之概略構成。圖9係本實 施形態之多方向輸入裝置丨具有之可撓性基板丨丨上安裝之

201124885 數個（本實施形態中為四個）GMR(GiarU Magnet0 Resistance：) 元件113a，放大來自該等GMR元件113a之輸出信號，並基 於放大後之輸出信號算出磁鐵8(操作體5)之滑動位置之控 制電路113b。此處，作為基本之構成，GMR元件U3a於可 撓性基板11上積層反鐵磁性層、栓層、中間層及自由層而 形成。 於磁感測器113中’使來自由保持構件9保持之磁鐵8之 磁通量作用於GMR元件113a，藉由磁通量之方向使其電阻 值產生變化。例如，將磁鐵8於磁感測器1丨3側磁化為N極 而於操作體5側磁化為s極時，來自磁鐵8之磁通量大致如 圖10所示之箭頭所示產生（再者，於圖1〇所示之紙面近前 側及裏側亦同樣產生）。於磁感測器丨13中，由四個GMR元 件113a構成電橋電路，並基於與一對GMR元件U3a中之電 阻值之變化相對應之輸出信號及與另一對GMR元件Η 3 a中 之電阻值之變化相對應之輸出信號之差異，算出磁鐵8(操 作體5)之滑動位置。 再者，該磁感測器113所包含之GMR元件113a為了發揮 巨大磁阻效應，例如，較佳為反鐵磁性層由a_Fe2〇3層形 成、栓層由NiFe層形成、中間層由cu層形成、自由層由 NiFe層形成，但並不侷限於此，只要為能發揮磁阻效應之 層即可。而且，磁感測器113所包含之GMR元件U3a只要 為發揮磁阻效應之元件即可，並不侷限於上述之積層構 造。 其次，說明本實施形態之多方向輸入裝置1具有之安裝 149980.doc 17 201124885 構件4之構成以及安裝構件4與可撓性基板丨i之位置關係。 圖11係本實施形態之多方向輸入裝置1具有之安裝構件4之 俯視圖（該圖（a))及側視圖（該圖。圖12係用於說明本實 施形態之多方向輸入裝置1具有之安裝構件4及可撓性基板

In the S-Hood direction input device, a flexible substrate on which a magnetic sensor is mounted is placed on a mounting member (bottom cover) made of a metal plate, and magnetic sensing is performed. The present invention is sandwiched between the above-mentioned flexible substrate and the lower surface of the lower casing. [Prior Art] [Patent Document 1] [Patent Document 1] Japanese Patent Laid-Open Publication No. 2008-47389, FIG. 1 [Summary of the Invention] The problem to be solved by the invention] However, in the above-described multi-directional input device, when the device body is dropped or stepped on, the magnetic sensor has a strong impact such that the operating body abuts against the magnetic sensor. In case of damage, especially when the magnetic sensor is fixed to the flexible substrate by solder, the solder is partially peeled off. 149980. Doc -4- 201124885 [Technical means for solving the problem] The present invention has been made in view of such actual circumstances. The object of the present invention is to provide a multi-directional input device in which a magnetic sensor is difficult to be broken.

Further, the magnetic sensor 11 3 mounted on the flexible substrate 11 will be described below. When the multi-directional input device 1 having the above configuration is assembled, as shown in Fig. 3, the operation portion 51 of the operation body 5 is in a state of protruding upward from the upper casing 2. In the inside of the multi-directional input device 1, as shown in Figs. 4 and 5, a holding member 9 in a state in which the magnet 8 is held is placed above the flat portion of the protruding portion 32 of the lower casing 3. That is, in the initial state 2 in which the operating body 5 is not slidably moved, the protruding portion 32 and the holding member 9 are opposed to each other so as to overlap each other in the up-and-down direction of Fig. 4 or the like. The spiral yellow 1() is slightly extended from the unloaded state so as to surround the periphery of the (four) protruding portion 保持 holding member 9: disposed on the bottom surface portion 31 of the lower casing 3, as shown in Figs. 4 and 5 The moving portion 52 of the staying body 5 and the bottom surface #31' holding the holding member of the magnet 8 are more specifically opposed to the magnetic sensor 113 in the vertical direction of the drawing via the flat portion of the protruding portion Configuration. 149980. Doc 13 201124885 #作体5 is arranged such that the operation portion 5i protrudes toward the outside of the apparatus, and the movement of the spiral yellow 1〇 to the upper side (the operating body (10)) is restricted by the movement 452. In other words, the moving portion 52 is disposed away from the bottom surface portion of the lower casing 3 so as to be substantially parallel to the bottom surface portion 31, and the upper portion of the coil spring 1 is restricted from the upper portion of the coil spring 1 via the partition member 7 and the lower portion is restricted by the partition member 7 3 1 limit. Further, with the (7) movement of the operating body 5, the coil spring 1 is elongated and deformed in the space portion formed between the bottom surface portion 31 of the lower casing 3 and the moving portion 52 (spacer member 7). The restricting member 6 is disposed in a state of being housed in a portion of the lower surface of the moving portion 52, and the restricting piece 62 is opposed to each other so as to be guided along the inner wall surface of the side wall portion 23a of the upper casing 2 with a gap of micro J. Refer to Figure 4). Further, at this time, the front end of the restricting piece 62 is separated from the bottom surface portion of the lower casing 3 so as not to come into contact with each other. The spacer member 7 is disposed between the moving portion 52 of the operating body 5 and the plate-like portion of the restricting member 6 and the coil spring 10. By arranging the partition member 7 between the movable portion-like plate portion 61 and the coil spring 10, even when a gap is formed between the concave portion 54 of the moving portion 52 and the restricting member 6, the coil spring 10 can be prevented from being suspended by the partition member 7. In the case of being clamped in the gap, even if the relatively inexpensive coil spring 10 is included as the elastic member, the operability of the device is not impaired.操作 Operation body 5 and limitation Fig. 6 shows the present embodiment. Here, the relationship between the member 6, the spacer member 7, and the holding member 9 disposed in the cavity portion of the casing will be described. FIG. 7 is a perspective view showing the relationship between the operation body 5 and the restriction member 6 in the multi-directional input device.

As shown in Fig. 6, the restricting member 6 is disposed on the concave portion 54 formed on the lower surface of the moving portion 52 of the operating body 5 so as to span the concave portion 55. As described above, the width of the plate-like portion 61 of the restricting member 6 in the width direction (γ direction) is set to be substantially the same as the width of the recessed portion 54 (strictly narrower than the width of the recessed portion 54). Therefore, the plate-like portion 61 becomes The state of entering the recess 54. On the other hand, the restricting piece 62 of the restricting member 6 is opposed to each other so as to be restricted by the inner wall surface of the side wall portion 23a of the upper casing 2. Therefore, when a rotational force is applied to the operation body 5, the operation body 5 is restricted by engaging the side wall portion 54a of the concave portion 54 with the end surface 61& of the plate portion 61 and bringing the restriction piece 62 into contact with the inner wall surface of the side wall portion 23a. Rotation. Further, in the restricting member 6, since the plate-like portion 61 is housed in the recessed portion 54 and the regulating piece 62 is disposed to face the inner wall surface of the side wall portion 23a of the upper casing 2, the restricting member 6 is restricted by the side wall portion 23a. The sliding movement in the χ direction shown in Fig. 6 allows the movement in the γ direction shown in the figure. The side wall portion 54a of the recessed portion 54 is formed at a position opposite to the X direction of the drawing in a state in which the central portion of the moving portion 52 extends in the z-direction. Further, when the operation body 5 is slidably moved in the Y direction shown in Fig. 6, the side wall portion 54a of the concave portion 54 is engaged with the end surface 61a of the plate portion 61, and the operation body 5 and the restriction member 6 are integrally slidably moved. In the state in which the magnet 8 is housed in the accommodating portion 91, the holding member 9 is fixed to the recess 55 by the fixing mechanism ID such as an adhesive. In this case, as shown in Fig. 7, the holding member 9 is held between the moving portion of the operating body 5 and 149980. Doc 201124885 The restriction member 6 is fixed to the recess 55. At this time, the restricting member 6 is disposed to be inserted between the moving portion 52 and the holding member 9. The spacer member 7 is disposed to face the moving portion 52 of the operating body 5 and the plate portion 61 of the restricting member 6 in a state where the holding member 9 protrudes downward from the opening 71. In a state of being fixed in this manner, as shown in Fig. 8, the holding member 9 is in a state of being integrated with the operating body 5. The coil spring 1 is disposed on the outer circumferential side of the projections 32 of the holding member 9 and the lower casing 3 thus arranged. The magnet 8 is housed inside the holding member 9, and the magnet 8 is similarly slidably moved in response to the sliding movement of the operating body. Thereby, the holding member is also a member provided in the moving portion of the operating body 5 which is slidably moved in the hollow portion between the upper casing 2 and the lower casing 3. The magnetic sensor 113 mounted on the flexible substrate detects the position of the sliding movement of the operating body 5 by detecting a change in the magnetic field generated by the magnet 8 thus moved, specifically, a change in the direction of the magnetic flux. (sliding position). Here, a schematic configuration of the magnetic sensor 113 mounted on the flexible substrate 11 of the multidirectional input device 1 of the present embodiment will be described.

Here, as a basic configuration, the GMR element U3a is formed by laminating an antiferromagnetic layer, a plug layer, an intermediate layer, and a free layer on the flexible substrate 11. In the magnetic sensor 113, the magnetic flux from the magnet 8 held by the holding member 9 is applied to the GMR element 113a, and the resistance value thereof is changed by the direction of the magnetic flux. For example, when the magnet 8 is magnetized to the N pole on the side of the magnetic sensor 1丨3 and magnetized to the s pole on the side of the operating body 5, the magnetic flux from the magnet 8 is generated substantially as indicated by the arrow shown in FIG. 10 (again, The same applies to the front side and the back side of the paper shown in Fig. 1A). In the magnetic sensor 丨13, the bridge circuit is constituted by four GMR elements 113a, and based on the output signal corresponding to the change in the resistance value in the pair of GMR elements U3a and the pair of other GMR elements Η 3 a The sliding position of the magnet 8 (operating body 5) is calculated by the difference in the resistance value corresponding to the difference in the output signal. Further, in order to exert a giant magnetoresistance effect, the GMR element 113a included in the magnetic sensor 113 is preferably formed of an a-Fe2〇3 layer, a plug layer formed of a NiFe layer, and an intermediate layer consisting of a cu layer. The formation and free layer are formed of a NiFe layer, but are not limited thereto, and may be any layer that exhibits a magnetoresistance effect. Further, the GMR element U3a included in the magnetic sensor 113 is not limited to the above-described laminated structure as long as it is an element exhibiting a magnetoresistance effect.

Fig. u shows the multidirectional input device 1 of the present embodiment from the lower side. The base member 41' having a planar shape at the upper end portion and the lower end portion of the mounting member 4 on the upper side and the lower side of the base portion 41 has four substantially L-shaped characters, respectively. The engagement piece 42 of the elastic piece of the shape is bent. The vicinity of the connection portion of the engagement piece 42 and the base portion 41 is slightly bent downward (the right side of FIG. 11(b)), and as shown in FIG.

As shown in Fig. 13, the opening portion 42a and the protruding card provided on the side wall portion 23 of the upper casing 2 are provided. The joint portion 24 is engaged and engaged, and the upper casing 2 and the lower casing 3 are integrated in a state in which the operation body 5 or the like is housed therein. In the center of the mounting member 4, a plate-like portion 43 extending in a strip shape in the left-right direction as shown in Fig. 11(a) is disposed between the pair of base portions 41. As shown in Fig. 11 (b) The portion 43 is provided at a lower position than the base portion 41 (that is, on the right side shown in FIG. 11(b)). The plate portion 43 is protruded downward from the base portion 41 and the plate portion 43. In the multi-directional input device 1 of the present embodiment, the bent portions 41a and 41b are provided between the base portion 41 and the plate-like portion 43 to ensure the strength of the mounting member * 0 149980 . Doc • 18· 201124885 . The central portion of the plate-like portion 43 is formed with a pair of elastic wrist structures and peaches. The elastic arms 44a and 44b are configured to extend toward the center side from the outer side of the plate-like portion 43 (the left side and the right side as shown in Fig. 4 (4)). The elastic arms 44a, 44b are formed such that the slits 45a of the first slits are extended along the longitudinal direction of the plate-like portion 43 (i.e., the left-right direction of the figure ()) The width direction of the portion 43 (the direction shown in FIG. u(a)) is formed by a knife blade, and a slit 45ce as a second slit connecting the central portions of the two portions is formed, and the elastic arms 44a and 4 are formed. The long holes 46a and 46b which are long in the left-right direction shown in Fig. 11 (4) are formed in the center of the servant. Thus, by forming the slits 45a to 45c and the long holes 46a and 4, the elastic wrist is formed. The crucibles 44a and 44b have a substantially U-shape, and both end portions thereof are connected in the vicinity of the side end portions of the plate-like portion 43 and their free ends are disposed at positions close to each other. Further, although not clearly shown in the drawings, the bending ends of the elastic arms 44a to 44b and the both end portions in the vicinity of the connecting portion of the plate-like portion 43 are subjected to a bending force. The free ends of the turns 44a and 44b are slightly higher than the upper side of the plate surface of the plate portion 43 (the left side in Fig. 11(b)). In the directional input device 1 of the present embodiment, the elastic arm portion 44a can be easily formed on the attachment member 4 only by forming the plurality of slits 45a to 45c and the long holes 46a and 46b in the plate-like portion of the attachment member 4, 44b. As shown in Fig. 12 (a) and (b), the flexible substrate 11 attached to the lower casing 3 is placed under the upper side of the plate-like portion 43 between the pair of bent portions 41a and 41b.

Thereby, the vicinity of the magnetic sensor 113 to which the flexible substrate is placed is applied to the lower side (that is, the right side shown in the back side of the paper shown in FIG. 12(a) or FIG. 12(1)). When the impact is moved, the elastic arms 44a and 44b are bent to absorb the impact. Further, as shown in Fig. 12 (b), a gap larger than the thickness of the flexible substrate 丨丨 is provided between the plate-like portion of the mounting member 4 and the lower surface of the bottom surface portion 31 of the lower casing 3.
