〔專利文獻1〕：日本特開2006-2779 82號公報 【發明內容】 然而，前述多方向輸入裝置中，必須有共計四個之磁 鐵，零件數量及組裝工時較多而生產性較低。 又，由於組裝於前述操作構件2之環狀磁鐵9，其只 Q 不過是僅有內周面被安裝於操作構件2,故保持強度較低。 因此，環狀磁鐵9會有因來自外部之衝擊力而掉落之虞， 爲了防止此情形卻另有必須具有較高之零件精度及組裝精 度等之問題點。 本發明之多方向輸入裝置，其課題在於提供一種零件 數量及組裝工時較少，且組裝於操作構件之可動磁鐵不易 脫落，亦無須較高之零件精度及組裝精度的多方向輸入裝 置0 201037752 〔用以解決課題之手段〕 爲了達成前述課題，本發明之多方向輸入裝置係將組 裝成與板狀可動磁鐵之至少兩面直接接觸的操作構件配置 於固定在基座之上面的環狀固定磁鐵內，且可從被覆該環

又，由於係將板狀可動磁鐵之至少兩面固定成與操作 構件直接接觸，因此板狀可動磁鐵之保持強度較高而不易 脫落。因此，無須較高之零件精度及組裝精度而更進一步 〇 提升生產性。 尤其，若以操作構件被覆板狀可動磁鐵之至少‘上面， 則從外部透過操作孔至板狀可動磁鐵之沿面距離變長，異 物等便不易附著。 本發明之實施形態，亦可設置成從操作構件之外周面 突設至側方之環狀鍔部之上下面之中，於其中一面組裝板 狀可動磁鐵的構成。 根據本實施形態，由於板狀可動磁鐵係與環狀鍔部$ 201037752 面接觸，因此保持強度更進一步提升而不易脫落。 本發明之其他實施形態，亦可設置成於從操作構件之 外周面突設至側方之上下一對環狀鍔部之間，配置板狀可 動磁鐵的構成。 根據本實施形態，由於板狀可動磁鐵之上下面係與一 對環狀鍔部作面接觸，因此保持強度更進一步提升而不易 脫落。 本發明之另一實施形態，亦可設置成沿環狀鍔部之外 Ο 周緣部突設與板狀可動磁鐵之外側面接觸之環狀翼肋的構 成。 ， 根據本發明，由於板狀可動磁鐵之至少兩面係與操作 構件直接接觸，因此可製得保持強度較高之多方向輸入裝 置。 又，環狀翼肋係存在於環狀固定磁鐵與板狀可動磁鐵 之間，而發揮作爲緩衝材之作用。因此，磁鐵彼此不會直 〇 接碰撞而可防止磁鐵之損傷。 本發明之不同實施形態，亦可設置成於位在操作孔正

呈大致正方形，且從其一片延伸有外部連接部1 1。此外 前述基座基板10 —方面係於其上面中央部以半球狀按 開關20被覆配置於同心圓上之中央接點部1 3及環狀接 部14,另一方面則於其角落部分別設有斂縫孔12。前述 球狀按鈕開關20係於半球狀按鈕部21之下面黏著有半 Q 狀可動接點22(參照第4圖）而形成一體化。另一方面， 述基座基板10係於其背面中央部設有用以連接檢測元 25之連接部15。再者，於前述基座基板10之背面係黏 有間隔件26而形成一體化，該間隔件26則設有用以保 前述檢測元件25之嵌合孔27。該間隔件26係具有避開 前述基座基板10之下面微幅突出之後述斂縫用突部33 功能。因此，在將本實施形態之多方向輸入裝置安裝於 子機器的安裝面時，可平行且穩定地固定。 少 持 組 圖 狀 裝 時 9 鈕 點 半 球 前 件 著 護 從 的 電 201037752 前述框狀殻體30具有可載置於前述基座10之平面形 狀，且具有可嵌合後述環狀固定磁鐵35的開口部31。又， 前述框狀殼體30係於其上面角落部突設有定位用突起 32，且於其下面角落部突設有斂縫用突部33。 前述環狀固定磁鐵35—方面具有可嵌合於前述框狀殼 體30之開口部31的外徑，另一方面則具有可載匱於前述 半球狀按鈕開關20之外周緣部的內徑。又，與後述環狀可 ^ 動磁鐵49同樣地，前述環狀固定磁鐵35係沿半徑方向充 磁，藉此使前述環狀固定磁鐵35之內周面與環狀可動磁鐵 49之外周面以同極相對向而使彼此互相推斥。 操作構件40 —方面係於其下端面設有操作用突起 41，另一方面則從其外周面將環狀鍔部42突設至側方。再 者，前述環狀鍔部42係沿其下面外周緣部突設有環狀翼肋 43，而可嵌合、固定環狀可動磁鐵49。此外，於操作構件 40，爲了改善滑動性亦可添加滑動劑以減低摩擦係數。 〇 外蓋50係可被覆前述框狀殻體30且俯視呈大致正方 形，一方面於其中央部設有操作孔51，另一方面則於其角 落部設有定位孔52。 尤其，若以磁性材來形成前述外蓋50，則操作構件40 可藉環狀可動磁鐵49之磁力吸附於外蓋50之下面，而呈 面接觸狀態。因此，具有操作構件40不易傾斜而可穩定操 作的優點。 其次，針對前述構成零件之組裝方法作說明。 201037752 首先，將半球狀按鈕開關20裝設於基座10之上面中 央。另一方面，將檢測元件25裝設於前述基座10之背面 中央部的連接部15，且將間隔件26之嵌合孔27嵌合於前 述檢測元件25，以將間隔件26黏著於前述基座1 0而形成 一體化。 接著，將框狀殼體30之斂縫用突部33嵌合於前述基 座10之斂縫孔12以進行定位並予以斂縫固定。接著，再 將環狀固定磁鐵35嵌合於前述框狀殼體30之開口部31， 〇 以防止半球狀按鈕開關20之外周緣部脫落。再者，將組裝 有環狀可動磁鐵49之操作構件40配置於前述框狀殼體30 內之後，將外蓋50之定位孔52嵌合、固定於前述框狀殼 體30之定位用突起32，藉此完成組裝作業。 接著，針對前述多方向輸入裝置之操作方法作說明。 例如，欲將前述多方向輸入裝置組裝於圖式中未顯示 之行動電話時，在操作前係以前述操作構件40之環狀可動 Q 磁鐵49與環狀固定磁鐵35彼此之推斥力，使前述操作構 件40被推壓至上方而浮起，而從操作孔51之中央突出。 接著，藉由使前述操作構件40滑動於橫方向，使得檢 測元件25檢測出前述環狀可動磁鐵49之位移方向及位移 量，而將與檢測資料對應之輸出資料從外部連接部11輸出 至外部電路。因此，藉由前述操作構件40之操作，前述行 動電話之顯示器內的圖示（icon)會移動至既定位置。接著， 藉由按下操作構件40，按鈕開關20之半球狀可動接點22 201037752 會被按下而反轉，使中央接點部13及環狀接點部ι4導通， 而輸出選擇指示訊號。 本實施形態中，如第5B圖所示，藉由環狀固定磁鐵 35與環狀可動磁鐵49彼此之磁力的推斥力，使操作構件 40浮起’並且隨時自動返回操作孔51之中央位置。 又，操作構件4 0與外蓋5 0之操作孔5 1之內側面的距 離X係較操作構件40之環狀翼肋43與環狀固定磁鐵35之 內側面的距離Y長。因此，由於操作構件40之環狀蟹肋 〇 43抵接於環狀固定磁鐵35，因此操作構件40不會抵接於 外蓋50，亦不會造成損傷。 再者，由於前述操作構件40之環狀鍔部42的上面與 外蓋50的下面係形成面接觸，因此前述操作構件40不易 傾斜而可進行正確之操作。 此外，如第6圖所示之第2實施形態，前述間隔件26 藉由設成與檢測元件25同等以上之厚度尺寸，可將多方向 Q 輸入裝置之本體平行且穩定地固定於電子機器之安裝面， 具有可更進一步確實地保護前述檢測元件25的優點。 又，如第7A圖至第7D圖所示之第1實施形態，由於 操作構件40係與環狀可動磁鐵49之三面直接接觸，因此 組裝作業容易且生產性高。再者’由於從外部至環狀可動 磁鐵49之沿面距離變長，因此具有異物等不易附著的優 點。又，例如，如第7E圖至第7H圖所示之第3實施形態， 亦可爲將前述環狀可動磁鐵49之三面予以被覆’且其兩面 -10- 201037752 直接接觸之情形。 再者’操作構件40係如第8A圖至第8D圖所示之第4 實施形態’不一定需要操作構件40之環狀翼肋，亦可具有 環狀可動磁鐵49不抵接於環狀固定磁鐵35之外徑的環狀 鍔部42’且使環狀可動磁鐵49之兩面直接接觸。又，環狀 可動磁鐵49並不限於載置環狀鍔部42之下面，如第8E圖 至第8H圖所示之第5實施形態，亦可載置於環狀鍔部42 之上面^ 〇 此外’如第9A圖至第9D圖所示之第6實施形態般， 操作構件40即使在將環狀可動磁鐵49載置於環狀鍔部42 之上面的情況下，亦可將環狀翼肋43突設於前述環狀鍔部 42之外周緣部，而使環狀可動磁鐵49之三面直接接觸。 又’如第9E圖至第9H圖所示之第7實施形態，亦可藉由 以環狀鍔部42, 44被覆環狀可動磁鐵49之上下面，而使環 狀可動磁鐵49之三面直接接觸。 ❹ 再者，如第10A圖至第10D圖所示之第8實施形態， 操作構件40亦可以鍔部42, 44及環狀翼肋43被覆環狀可 動磁鐵49之四面。尤其，可動磁鐵49不限於圓環形狀， 亦可如第10E圖至第10H圖所示之第9實施形態般爲圓板

Description of the Invention: [Technical Field] The present invention relates to a multi-directional input device, and more particularly to a slidable operation to the side and for use in electronic devices such as mobile phones, PCs, PDAs, televisions, and video. Multi-directional input device. [Prior Art] As a multi-directional input device, for example, as disclosed in FIG. 1 of the patent document, the repulsive force and the ring-shaped magnet 9 are provided so as to be reciprocating between the disc-shaped magnets 7, 11 and The repulsive force of each other causes the operating member 2 to float and automatically return to the center. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2006-2779 82. SUMMARY OF THE INVENTION However, in the multi-directional input device, a total of four magnets are required, and the number of components and the number of assembly steps are large, and the productivity is low. Moreover, since the ring magnet 9 assembled to the operation member 2 is only Q, only the inner peripheral surface is attached to the operation member 2, the holding strength is low. Therefore, the ring magnet 9 may fall due to an impact force from the outside, and in order to prevent this, it is necessary to have a problem of high part accuracy and assembly accuracy. The multi-directional input device of the present invention has an object of providing a multi-directional input device in which the number of components and assembly man-hours are small, and the movable magnet assembled to the operating member is not easily detached, and high component accuracy and assembly accuracy are not required. [Means for Solving the Problem] In order to achieve the above-described object, the multidirectional input device of the present invention is configured such that an operation member assembled in direct contact with at least two surfaces of a plate-shaped movable magnet is disposed on an annular fixed magnet fixed to the upper surface of the base. And operating the operating member from an operation hole covering the outer cover of the annular fixed magnet, which is arranged to slide the operating member along the lower surface of the outer cover, thereby detecting by the detecting element provided on the base The change in the magnetic force of the plate-like movable magnet is performed, and on the other hand, the urging force of the ring-shaped fixed magnet and the plate-like movable magnet can automatically return the 0-operation member to the center position. According to the present invention, since the operating member is floated with only two magnets and can be automatically returned to the center position, the number of parts and the number of assembly man-hours are small to improve productivity. Further, since at least two faces of the plate-like movable magnet are fixed in direct contact with the operation member, the plate-like movable magnet has a high holding strength and is not easily peeled off. Therefore, it is possible to further improve productivity without requiring high part accuracy and assembly accuracy. In particular, when at least the upper surface of the plate-shaped movable magnet is covered by the operating member, the distance from the outside through the operation hole to the surface of the plate-like movable magnet becomes long, and foreign matter or the like is less likely to adhere. In the embodiment of the present invention, the outer peripheral surface of the operating member may be protruded from the upper and lower surfaces of the side annular portion, and the plate-like movable magnet may be assembled on one side. According to the present embodiment, since the plate-shaped movable magnet is in surface contact with the annular crotch portion $201037752, the holding strength is further increased and it is not easy to fall off. According to still another embodiment of the present invention, the plate-like movable magnet may be disposed so as to protrude from the outer peripheral surface of the operating member to the side between the pair of upper and lower annular rims. According to the present embodiment, since the upper and lower sides of the plate-shaped movable magnet are in surface contact with a pair of annular crotch portions, the holding strength is further improved and it is not easy to fall off. According to still another embodiment of the present invention, the annular rib which is in contact with the outer surface of the plate-like movable magnet may be formed to protrude from the periphery of the annular beak. According to the present invention, since at least two faces of the plate-like movable magnet are in direct contact with the operating member, a multi-directional input device having a high holding strength can be obtained. Further, the annular rib is present between the annular fixed magnet and the plate-shaped movable magnet, and functions as a cushioning material. Therefore, the magnets do not collide with each other and the magnets are prevented from being damaged. Different embodiments of the present invention may be provided on the upper surface of the susceptor located directly below the operation hole, and the push button switch may be configured to be operable by the operation member. According to the present invention, a multi-directional input device capable of detecting not only the displacement of the operating member but also a selection instruction and making a plurality of functions is provided. The electronic device of the present invention is arranged to mount the operating member of the multi-directional input device as Configuration from the outside of the casing" 201037752 According to the present invention, an electronic machine in which the number of parts and the assembly time is changed and the productivity is high can be obtained. Further, since the plate-shaped movable magnet has a high strength and is not easily detached, it is possible to further produce an electronic device having higher productivity without requiring high part precision and assembly accuracy. [Embodiment] The first embodiment of the multidirectional input device of the present invention is a susceptor 10, a frame case 30, and a ring-shaped fixed magnet 35 which are formed of a hard printed circuit board as shown in the first to fifth figures. The annular movable magnet 49 is integrally formed by the operation member 40 and the outer cover 50. As shown in Figs. 3 and 4, the base substrate 10 has a substantially square shape in plan view, and an external connecting portion 11 extends from one of the base plates 10. Further, the base substrate 10 is provided with a central contact portion 13 and a ring-shaped connecting portion 14 which are arranged on the concentric circle in a hemispherical shape at a central portion thereof, and are provided at the corner portions thereof. There are caulking holes 12. The spherical push button switch 20 is integrally formed by adhering a semi-Q-shaped movable contact 22 (see Fig. 4) to the lower surface of the hemispherical button portion 21. On the other hand, the base substrate 10 is provided with a connecting portion 15 for connecting the detecting unit 25 at the center portion of the back surface. Further, a spacer 26 is adhered to the back surface of the base substrate 10 to be integrated, and the spacer 26 is provided with a fitting hole 27 for protecting the detecting element 25. The spacer 26 has a function of avoiding the micro-protrusion of the lower surface of the base substrate 10 and then caulking the projection 33. Therefore, when the multidirectional input device of the present embodiment is attached to the mounting surface of the sub-machine, it can be fixed in parallel and stably. When the group image is mounted in a small amount, the button-shaped housing 30 has a planar shape that can be placed on the susceptor 10, and has a ring-shaped fixed magnet 35 that can be fitted later. The opening portion 31. Further, the frame-shaped casing 30 is provided with a positioning projection 32 at its upper corner portion, and a caulking projection 33 is formed at a lower corner portion thereof. The annular fixed magnet 35 has an outer diameter that can be fitted into the opening 31 of the frame-shaped casing 30, and has an inner diameter that can be placed on the outer peripheral portion of the hemispherical push button switch 20. Further, similarly to the ring-shaped movable magnet 49, which will be described later, the annular fixed magnet 35 is magnetized in the radial direction, whereby the inner circumferential surface of the annular fixed magnet 35 and the outer peripheral surface of the annular movable magnet 49 are The same poles oppose each other and repel each other. The operation member 40 is provided with an operation projection 41 on its lower end surface, and the annular flange portion 42 is protruded from the outer circumferential surface thereof to the side. Further, the annular flange portion 42 has an annular rib 43 projecting from the outer peripheral edge portion of the lower surface thereof to fit and fix the annular movable magnet 49. Further, in the operating member 40, a sliding agent may be added to improve the sliding property to reduce the friction coefficient. The outer cover 50 is covered with the frame-shaped casing 30 and has a substantially square shape in plan view. On the other hand, the operation hole 51 is provided at the center portion thereof, and the positioning hole 52 is provided at the corner portion thereof. In particular, when the outer cover 50 is formed of a magnetic material, the operating member 40 can be attracted to the lower surface of the outer cover 50 by the magnetic force of the annular movable magnet 49 to be in surface contact state. Therefore, there is an advantage that the operating member 40 is less inclined and can be stably operated. Next, an explanation will be given of an assembly method of the above-described constituent parts. 201037752 First, the hemispherical button switch 20 is mounted on the upper center of the base 10. On the other hand, the detecting element 25 is attached to the connecting portion 15 at the central portion of the back surface of the susceptor 10, and the fitting hole 27 of the spacer 26 is fitted to the detecting element 25 to adhere the spacer 26 to the foregoing. The pedestal 10 is integrated. Next, the caulking projection 33 of the frame-shaped casing 30 is fitted to the caulking hole 12 of the base 10 to be positioned and fixed by caulking. Then, the annular fixed magnet 35 is fitted into the opening 31 of the frame-shaped casing 30 to prevent the outer peripheral portion of the hemispherical push button switch 20 from coming off. Further, after the operation member 40 in which the annular movable magnet 49 is assembled is placed in the frame-shaped casing 30, the positioning hole 52 of the outer cover 50 is fitted and fixed to the positioning projection 32 of the frame-shaped casing 30. In order to complete the assembly work. Next, an operation method of the multi-directional input device will be described. For example, when the multi-directional input device is to be incorporated in a mobile phone not shown in the drawings, the repulsive force between the ring-shaped movable Q magnet 49 and the ring-shaped fixed magnet 35 of the operating member 40 is used before the operation. The operation member 40 is pushed up to float upward and protrudes from the center of the operation hole 51. Then, by sliding the operation member 40 in the lateral direction, the detecting element 25 detects the displacement direction and the displacement amount of the annular movable magnet 49, and outputs the output data corresponding to the detected data from the external connection portion 11 to the outside. Circuit. Therefore, by the operation of the aforementioned operating member 40, the icon in the display of the aforementioned mobile phone moves to a predetermined position. Then, by pressing the operation member 40, the hemispherical movable contact 22 201037752 of the push button switch 20 is pressed and reversed, and the central contact portion 13 and the annular contact portion ι4 are turned on to output a selection instruction signal. In the present embodiment, as shown in Fig. 5B, the operating member 40 is floated by the repulsive force of the magnetic force between the ring-shaped fixed magnet 35 and the annular movable magnet 49, and automatically returns to the center position of the operation hole 51 at any time. Further, the distance X between the operation member 40 and the inner side surface of the operation hole 5 1 of the outer cover 50 is longer than the distance Y between the annular rib 43 of the operation member 40 and the inner side surface of the annular fixed magnet 35. Therefore, since the annular crab rib 43 of the operating member 40 abuts against the annular fixed magnet 35, the operating member 40 does not abut against the outer cover 50 and does not cause damage. Further, since the upper surface of the annular flange portion 42 of the operation member 40 is in surface contact with the lower surface of the outer cover 50, the operation member 40 is less likely to be inclined and can be correctly operated. Further, in the second embodiment shown in Fig. 6, the spacer 26 can be fixed to the electronic device in parallel and stably with the body of the multi-directional Q input device by the thickness equal to or larger than that of the detecting element 25. The mounting surface has the advantage that the aforementioned detecting element 25 can be further protected. Further, in the first embodiment shown in Figs. 7A to 7D, since the operation member 40 is in direct contact with the three faces of the annular movable magnet 49, the assembly work is easy and the productivity is high. Further, since the distance from the outside to the ring-shaped movable magnet 49 becomes longer, there is an advantage that foreign matter or the like is less likely to adhere. Further, for example, in the third embodiment shown in Figs. 7E to 7H, the three sides of the annular movable magnet 49 may be covered and the two sides of the ring-shaped -10-201037752 may be in direct contact with each other. Further, the 'operation member 40 is a fourth embodiment shown in Figs. 8A to 8D. 'The annular rib of the operation member 40 is not necessarily required, and the annular movable magnet 49 may not be abutted against the annular fixing. The annular flange portion 42' of the outer diameter of the magnet 35 is in direct contact with both surfaces of the annular movable magnet 49. Further, the annular movable magnet 49 is not limited to the lower surface on which the annular flange portion 42 is placed, and may be placed on the upper surface of the annular flange portion 42 as in the fifth embodiment shown in Figs. 8E to 8H. Further, as in the sixth embodiment shown in FIGS. 9A to 9D, the operating member 40 may be provided with the annular wing even when the annular movable magnet 49 is placed on the upper surface of the annular flange portion 42. The rib 43 protrudes from the outer peripheral edge portion of the annular flange portion 42, and the three faces of the annular movable magnet 49 are in direct contact with each other. Further, as in the seventh embodiment shown in Figs. 9E to 9H, the three sides of the annular movable magnet 49 may be directly covered by the upper and lower surfaces of the annular movable magnet 49 by the annular flange portions 42, 44. contact. Further, in the eighth embodiment shown in Figs. 10A to 10D, the operation member 40 may cover the four sides of the annular movable magnet 49 with the crotch portions 42, 44 and the annular rib 43.
