L、〇U T P U 丁- R。此等輸出端子係與判定邏輯部5連 接，伴隨著操作旋鈕2的被操作而使得塑膠磁鐵3移動， 而於判定邏輯部5輸出響應從該塑膠磁鐵3施及各霍爾元 件4的磁性強弱的輸出電壓。 具體而言，在操作旋鈕2位於中間位置時，第1塑膠磁 鐵3 a及第2塑膠磁鐵3 b的兩者，與第1霍爾元件4 a、第 2霍爾元件4 b分別對向而形成最接近的狀態，施及各霍爾 元件4的磁性成為強磁狀態。據此，因為兩霍爾元件4的 電阻值成為低電阻值，從圖8可知，輸出端子OUTPUT-L、 0 U T P U T - R的輸出電壓成為雙方均低的值（L )。 當從中間位置向右方向搖動操作旋鈕2時，便成為圖5 的狀態，維持第1塑膠磁鐵3 a與第1霍爾元件4 a的近接 狀態，同時，第2塑膠磁鐵3 b從第2霍爾元件4 b離開。 藉此，維持施及第1霍爾元件4a的磁性強度，另一方面， 施及第2霍爾元件4b的磁性強度變弱，因此輸出端子 0 U T P U ΐ - L的輸出電壓成為高電壓值（Η )，同時，0 U T P U T - R 的輸出電壓成為低電壓值（L)。 相反，當從中間位置向左方向搖動操作旋鈕2時，便成 為圖6的狀態，維持第2塑膠磁鐵3 b與第2霍爾元件4 b 的近接狀態，同時，第1塑膠磁鐵3a從第1霍爾元件4 a 3丨2/發明說明書(補件)/93-03/93丨00525 1丨 1230387 離開。藉此，維持施及第2霍爾元件4b的磁性強度，另一 方面，施及第1霍爾元件4a的磁性強度變弱，因此輸出端 子0 U T P U T - R的輸出電壓成為高電壓值（Η )，同時，0 U T P U T - L 的輸出電壓成為低電壓值（L )。 更且，當壓入操作旋鈕2而成為圖7的狀態時，第1塑 膠磁鐵3a及第2塑膠磁鐵3b的兩者，與第1霍爾元件4a、 第2霍爾元件4 b分別對向而形成最分離的狀態，施及各霍 爾元件4的磁性成為弱磁狀態。據此，因為兩霍爾元件4 的電阻值成為高電阻值，因此輸出端子OUTPUT-L及 0 U T P U T - R的輸出電壓成為雙方均高的值（Η )。 上述輸出電壓的變化被傳遞給判定邏輯部5。上述判定 邏輯部5係基於該輸出電壓，根據指定的判定邏輯來判斷 是否使二輪車所具備的左右任一的信號燈閃爍或熄燈，並 基於該判斷結果使指定的信號燈閃爍或熄燈。亦即，如圖 8所示，響應來自霍爾元件4輸出電壓來判定是否使左右 任一的信號燈閃爍或取消該信號燈的閃爍，基於上述結果 來構成或戴止指定的電路。 根據同圖可知，若向左側搖動操作上述操作旋鈕2時， 左側的信號燈閃爍，若向右側搖動操作上述操作旋鈕2 時，右惻的信號燈閃爍，並且，若壓入操作上述操作旋鈕 2 a寺，便取消信號燈的閃爍。另夕卜，操作旋鈕2在中間位 置維持前面的狀態，因此在操作後即使操作旋鈕2返回中 間位置，.仍可維持基於操作的閃爍或熄燈。 又，如圖3所示，在基板6的電路中，電阻元件R1〜R3 12 3丨2/發明說明ftf(補件)/93-03/93丨00525 1230387 連接於霍爾元件4 a側，同時，電阻元件R 4〜R 6連接於霍 爾元件4b側。藉由上述電阻元件，可將各霍爾元件4的輸 出電壓限定在指定的範圍，例如，在電源V c c的電壓為5 V 的情況，輸出電壓被限制在0 . 5 V〜4 . 5 V的範圍内。 藉此，在電線（未圖示）與端子7脫落的情況，或在電源 及輸出端子斷線的情況，輸出電壓成為0V，同時，在GND 斷線的情況，輸出電壓成為5 V (電源V c c的電壓為5 V的情 況），因此，輸出電壓超出上述的如0 . 5 V〜4 . 5 V的範圍， 在該情況可確認有斷線等的異常產生。 根據上述第1實施形態，利用2個霍爾元件4 (第1霍爾 元件4 a及第2霍爾元件4 b )，可執行左側的信號燈的閃爍 操作、右側的信號燈的閃爍操作及取消操作的3個操作。 因此，與具備需分別檢測操作旋鈕2的3個操作的3個磁 性檢測部比較，可削減轉向信號開關的製造成本。 其次，說明本發明之第2實施形態的轉向信號開關。又， 對與第1實施形態相同的構成，則賦予相同的元件符號， 並省略該詳細說明。 本實施形態的轉向信號開關，與第1實施形態相同，係 安裝於二輪車的操向手柄的把手附近，為可進行使該二輪 車具備的信號燈閃爍或熄燈的切換操作者，如圖9至圖1 2 所示，主要由盒子1、操作旋鈕2、塑膠磁鐵3、作為磁性 檢測部的角度感測器1 2、判定邏輯部5及屏蔽板1 4所構 成。 盒子1與第1實施形態相同，為如圖1 〇所示連結内部 13 3丨2/發明說明書(補件)/93-03/93100525 1230387 形成搖動軸1 C及搖動空間S的第1盒子1 a ;及内建具有 角度感測器1 2的基板6的第2盒子1 b而構成，基板6由 樹脂封裝。另外，在搖動空間S内形成調節度供給機構8， 利用螺旋彈簧1 0的彈性作用力的鋼珠1 1形成為可滑動 狀。藉此可取得搖動操作時的調節度，同時，當操作者的 手指離開操作旋鈕2時，該操作旋鈕2便經常返回中間位 置。 操作旋鈕2係形成以搖動軸1 c為中心而可從中間位置 向左右側搖動操作，在對應該搖動軸1 c的部位，在包覆該 搖動軸1 c前端的位置，形成突出於第2盒子1 b的塑膠磁 鐵3。藉此，當搖動操作上述操作旋鈕2時，形成於該搖 動中心的塑膠磁鐵3便轉動。 另外，在塑膠磁鐵3的側面配設有戴止磁性的屏蔽板 1 4，以限制該塑膠磁鐵3的磁性所能涉及的範圍。亦即， 塑膠磁鐵3的側面係由屏蔽板1 4所包圍，因此其磁性被限 定在與塑膠磁鐵3對向的位置。 另外，在與基板6上的塑膠磁鐵3對向的位置，固定有 1個角度感測器1 2。該角度感測器1 2係由依從磁鐵所釋出 的磁力線的方向來變化電阻值而使輸出電壓各異者，當伴 隨著操作旋鈕2的搖動操作而使塑膠磁鐵3旋轉時，響應 該磁力線的方向變化而使電阻值變^匕。 如圖1 1所示，上述角度感測器1 2係連接於基板6上配 設的放大器1 3，角度感測器1 2的輸出電壓介由放大器1 3 而被放大後，其放大值被傳輸至判定邏輯部5。介由放大 14 3丨2/發明說明書(補件)/93-03/93 100525 1230387 器1 3而被放大的輸出電壓，係設定為如圖1 3所示的輸出 波形，在操作旋鈕2位於中間位置時，成為A點，向左側 搖動操作時成為B點，向右側搖動操作時為C點，及壓入 操作上述操作旋紐2時成為D點。 尤其是，當伴隨著操作旋鈕2的壓入操作，塑膠磁鐵3 向下方移動時，該塑膠磁鐵3便離開角度感測器1 2而變得 不對向，因此，藉由屏蔽板1 4的作用，使得其磁性不施及 角度感測器1 2。藉此，當壓入操作上述操作旋鈕2時，成 為最小的輸出電壓（本實施形態的情況，為如圖1 3所示的 約 0 . 5 V )。 判定邏輯部5係基於該角度感測器1 2的輸出電壓，根 據指定的判定邏輯來判斷是否使二輪車所具備的左右任一 的信號燈閃爍或熄燈，並基於該判斷結果使指定的信號燈 閃爍或熄燈。亦即，如圖1 4所示，響應來自角度感測器 1 2的輸出電壓來判定是否使左右任一的信號燈閃爍或取 消該信號燈的閃爍，基於上述結果來構成或戴止指定的電 路。 根據同圖可知，若向左側搖動操作上述操作旋鈕2時， 左側的信號燈閃爍，若向右側搖動操作上述操作旋鈕2 時，右惻的信號燈閃爍，並且，若壓入操作上述操作旋鈕 2時，便取消信號燈的閃爍。另夕卜，操作旋鈕2在中間位 置維持前面的狀態，因此在操作後即使操作旋鈕2返回中 間位置，仍可維持基於操作的閃爍或熄燈。 根據上述第2實施形態，利用1個角度感測器1 2，可執 15 3 12/發明說明斟(補件)/93-03/93丨00525 1230387 行左側的信號燈的閃爍操作、右側的信號燈的閃爍操作及 取消操作的3個操作。因此，與具備3個或2個磁性檢測 部比較，可削減轉向信號開關的製造成本。另夕卜，藉由將 戴止磁性的屏蔽板1 4配置於塑膠磁鐵3的側面，在操作旋 鈕2的壓入操作時，可確實戴止波及角度感測器之來自塑 膠磁鐵的磁性，可更為正確進行取消操作時的判定邏輯部 的判定，可更為確實取消信號燈的閃爍。 以上，說明了第1實施形態及第2實施形態，但本發明 並不限於此等，例如，也可取代塑膠磁鐵而於操作旋鈕接 合永久磁鐵，只要可響應伴隨著與操作旋鈕的連動的磁鐵 移動的磁性變化而使輸出電壓變化者，便可使用與霍爾元 件及角度感測器不同的磁性檢測部。 另外，依判定邏輯部的判定也不限於上述實施形態的如 上方法，可作任意的設計。而且，雖然本實施形態中任一 情況均顯示安裝於二輪車的操向手柄的轉向信號開關，但 也可應用於雪上四輪傳動車、三輪或四輪傳動推車等的具 備操向手柄的其他車輛。 C發明效果） 根據如上述的申請專利範圍第1項之發明，因為基於操 作旋鈕的搖動操作及壓入操作使磁鐵移動，響應伴隨著該 移動的磁性變化使所需惻的信號燈閃爍，同時使該閃爍取 消，因此利用未使用接點的非接觸方式便可進行信號燈的 操作。因此，可避免起因於接點的磨耗所致的壽命減短， 同時，可確實避免盒子内滲水等引起的電性接觸不良。 16 3 12/發明說叨·(補件)/93-03/93 100525 1230387 根據申請專利範圍弟2項 執行左側的信號燈的閃爍操 及取消操作的3個操作。因 鈕的3個操作的3個磁性檢 關的製造成本。 根據申請專利範圍第3項 磁性檢測部的輸出電壓限定 此在輸出電壓超出其範圍的 異常。 另夕卜，根據申請專利範圍 感測器可執行左側的信號燈 閃爍操作及取消操作的3個 個磁性檢測㊂卩比較，可削減 根據申請專利範圍第5項 蔽板配置於磁鐵的側面，在 實戠止波及角度感測器之來 確進行取消操作時的判定邏 信號燈的閃爍。 【圖式簡單說明】 圖1 ( a )為顯示本發明之第 前視圖’圖1 ( b )為同右側視 圖2為沿著圖1 ( a )中之Π 圖3為顯示本發明之第1 板構成及與判定邏輯部的連 之發明，利用2個霍爾元件可 作、右側的信號燈的閃爍操作 此，與具備需分別檢測操作旋 測部比較，可削減轉向信號開 之發明，因為具備用以將來自 在指定範圍内的電阻元件，因 情況，可確認為產生斷線等的 第4項之發明，利用1個角度 的閃爍操作、右側的信號燈的 操作。因此，與具備3個或2 轉向信號開關的製造成本。 之發明，藉由將截止磁性的屏 操作旋鈕的壓入操作時，可確 自塑膠磁鐵的磁性，可更為正 輯部的判定，可更為確實取消 1實施形態的轉向信號開關的 圖。 -

[Prior art] Generally, steering signal switches are fixed near the handles on the left and right front ends of the steering handles of two-wheelers. The above-mentioned turn signals are respectively arranged on the left and right side signal lamps of the two-wheeled vehicle, and the switches for flashing or turning off the lights are conventionally fixed to a box; the rocking action of the operation knob knob protruding from the box and rotatable is moved A movable contact; and a configuration of a fixed contact fixed to the box movable contact to contact or separate (for example, as disclosed in 1). When the left-hand operation is moved to the middle of the operation, the rotary contact is moved, for example, the fixed contact on the right side can be contacted to form a circuit, which can make the signal light on the left side of the two-wheeler flicker. When moving, for example, the fixed contact on the left side contacts the movable contact circuit, which can cause the signal light on the right side of the two-wheeler to flash. When you push the operation knob in the other direction, you can forcibly turn off the flash and light. (Patent Document 1) 'Japanese Patent Application Laid-Open No. 7-2 5 4 3 2 8 No. 3 丨 2 / Invention Specification (Supplement) / 93-03 / 93 100525 This open operation requires the signal on the side to operate the handle; according to the sub-side of the operation, the movable contact can be shaped like patent documents. On the contrary, when the movable contact is formed to form another one, the direction should flicker. Signal 5 in 1230387 [Summary of the Invention] (Problems to be Solved by the Invention) However, in the case of the above-mentioned circuit that is known to flash a fixed fixed signal lamp, it is used as an on-signal switch. The push-in operation is higher than other moves. In addition, in the case of a two-wheeled vehicle, the built-in part cannot avoid the poor electrical contact of water seepage. Although the sealing member in the box is designed to completely prevent water seepage. In view of the upward signal switch, the present invention can surely avoid (conducting the problem) that the signal switch is turned on electrically to achieve the above purpose. Therefore, the service life of the movable contact is limited. In addition to the left-right direction of the operation knob, the blinking signal can be expected to be more fixed, so the Yamato snow four-wheel drive vehicle's movable contacts and fixed access to the box, there are concerns. In order to avoid water infiltration, the energy limit for preventing water infiltration and the difficulty in ensuring operation are reached, and those who cannot explain the situation are reached. Avoid the introduction of water caused by the contact into the box, etc. The scope of the patent application is because the movable contact is formed by contact. The wear degree between the left and right and the fixed contact can be made. In particular, the swing of the operation lamp 媳 lamp in the steering direction protrudes to the side and the sliding of the movable contact point greatly requires the life of the switch. The box of the vehicle point of the steering handle is exposed to the outside due to the leakage caused by the water leakage. The electrical contact caused by the unsealed member, but if the swinging gap of the knob is taken into account, the actual purpose of completely solving the problem is to provide a reduced life due to abrasion and poor electrical contact.

[Poor application mode] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The turn signal switch according to the first embodiment of the present invention is installed near the handle of a steering handle of a two-wheeled vehicle, and is an operator who can switch the blinking or extinguishing of a signal lamp provided in the two-wheeled vehicle, as shown in FIGS. 1 to 4. It is mainly composed of a box 1, an operation knob 2, a plastic magnet 3, a Hall element 4 as a magnetic detection section, and a determination logic section 5. Box 1 is made of a resin molded product that can be fixed near the handle of a steering handle included in a two-wheeler (not shown). As shown in FIG. 2, the interior is connected as shown in the figure to form a swing space relative to the base end of the operation knob 2. The first case 1 a of S and the second case 1 b having a substrate 6 having a Hall element 4 built therein are configured. 8 3 丨 2 / Invention Specification (Supplement) / 93-03 / 93 100525 1230387 On the upper part of the rocking space S of the first box 1 a, an integrally formed rocking shaft 1 c that can support the operation knob 2 freely and at the same time, ' The lower part is provided with an adjusting degree supplying mechanism 8 which constitutes an actuating protrusion on the lower part. That is, the upper surface of the adjustment degree supply mechanism 8 is formed in a slightly parabolic shape convex downward, and when the operation knob 2 is pivoted about the swing shaft 1c as the center, the adjustment degree at the time of operation is supplied to the operation knob 2. A receiving recess M1 is formed in the upper part of the second box 1b, and a hole M2 is formed in the lower part. Among them, a substrate forming the Hall element 4 and the terminal 7 is housed in the housing recess M1, and is simultaneously filled with a resin, whereby the entire substrate 6 is sealed with a resin. The front end side of the terminal 7 formed on the substrate 6 extends to the hole M2, and forms a connector 9 together with the hole M2. The operation knob 2 is formed to protrude upward from the box 1, and at the same time, it can be set on the rocking axis 1 c of the first box 1 a as a center to perform a rocking operation from the middle position, and can be protruded from the middle position (FIG. 1 Bottom) Press in. Specifically, the operation knob 2 is composed of a resin knob 2a that can be held by an operator or touched with a finger, and a rocking member 2b extending downward from the knob portion 2a. A long hole 2 ba extending in the vertical direction is formed in a substantially central portion of the swing member 2 b in the longitudinal direction. A swing shaft 1 c is inserted into the long hole 2 ba, and a notch 2 is formed upward from the lower end of the swing member 2 b. bb, the notch 2 bb is inserted into the steel ball 11 through the coil spring 10. The steel ball 11 is constantly acted downward by the coil spring 10, and is pressed against the upper surface of the adjustment degree supply mechanism 8. Therefore, when the left and right knobs 2a are operated by shaking, as shown in FIG. 5 or 9 3 丨 2 / Fahan Description Street (Supplement) / 93-03 / 93 丨 00525 1230387 As shown in FIG. 6, the operation knob 2 As a whole, the rocking operation is performed with the rocking shaft 1 c as a center. At the same time, the steel ball 11 moves against the elastic force of the coil spring 10 while sliding along the upper surface of the adjustment degree supply mechanism 8 and moves in the direction of embedding the gap 2 bb. When the operator's finger leaves the knob portion 2a, the steel ball 11 moves in the direction protruding from the notch 2 bb by the elastic force of the coil spring 10, and the upper (inclined surface) of the adjustment degree supply mechanism 8 is used. After the force is divided, the entire operation knob 2 returns to the intermediate position (that is, the state shown in FIG. 4). On the other hand, when the handle portion 2 a is pushed in downward, as shown in FIG. 7, because the long hole 2 ba allows the entire operation knob 2 to move downward, it opposes the elastic force of the coil spring 10. Operation knob 2 moves downward. When the operator's finger leaves the knob part 2a, the elastic force of the coil spring 10 causes the operation knob 2 to move upward and return to the middle position. Here, a plastic magnet 3 is formed on the operation knob 2 instead of the conventional movable contact. The plastic magnet 3 is formed by mixing magnetic magnetic powder into plastic, and is formed by protruding from the lower part of the operation knob 2 in the left-right direction. That is, when the operation knob 2 is shaken or pushed in, the pair of plastic magnets 3 can be moved in the left-right direction or the up-down direction based on this action. For convenience, as shown in FIG. 4, let the plastic magnet 3 protruding to the left of the operation knob 2 be the first plastic magnet 3a, and the plastic magnet 3 protruding to the right of the operation knob 2 be the second plastic magnet 3b. . The Hall element 4 changes the resistance value in response to the strength of the magnetic force released from the magnet and varies the output voltage. As shown in FIG. 4, two of the first Hall element 4 a and the second Hall element 4 b It is fixed on the substrate 6. Respective Hall 10 312 / Invention Specification (Supplement) / 93-03 / 93100525 1230387 Elements 4 a and 4 b are fixed to the opposite sides of the plastic jump magnets 3 a and 3 b when the operation knob 2 is in the middle position. To the specified position on the substrate 6. As shown in FIG. 3, the first noise element 4a and the second Hall element 4b are connected in parallel to the power source V cc, and at the same time, they are respectively connected to the output terminals 0 U ding PUT-L, 〇UTPU ding- R. These output terminals are connected to the decision logic unit 5, and the plastic magnet 3 is moved as the operation knob 2 is operated, and the output of the decision logic unit 5 responds to the magnetic strength applied to the Hall elements 4 from the plastic magnet 3. Output voltage. Specifically, when the operation knob 2 is located at the middle position, both the first plastic magnet 3 a and the second plastic magnet 3 b are opposed to the first Hall element 4 a and the second Hall element 4 b, respectively. The closest state is formed, and the magnetism applied to each Hall element 4 becomes a ferromagnetic state. Accordingly, since the resistance value of the two Hall elements 4 becomes a low resistance value, it can be seen from FIG. 8 that the output voltages of the output terminals OUTPUT-L and 0 U T P U T-R are both low values (L). When the operation knob 2 is shaken to the right from the middle position, the state shown in FIG. 5 is maintained, and the close state between the first plastic magnet 3 a and the first Hall element 4 a is maintained, and at the same time, the second plastic magnet 3 b is changed from the second Hall element 4b leaves. Thereby, the magnetic strength applied to the first Hall element 4a is maintained, while the magnetic strength applied to the second Hall element 4b is weakened, so the output voltage of the output terminal 0 UTPU ΐ-L becomes a high voltage value ( Η), at the same time, the output voltage of 0 UTPUT-R becomes a low voltage value (L). Conversely, when the operation knob 2 is shaken from the middle position to the left, the state shown in FIG. 6 is maintained, and the close state between the second plastic magnet 3 b and the second Hall element 4 b is maintained, and at the same time, the first plastic magnet 3 a is moved from the first 1 Hall element 4 a 3 丨 2 / Invention specification (Supplement) / 93-03 / 93 丨 00525 1 丨 1230387 Leave. Thereby, the magnetic strength applied to the second Hall element 4b is maintained, while the magnetic strength applied to the first Hall element 4a is weakened, so the output voltage of the output terminal 0 UTPUT-R becomes a high voltage value (Η ), At the same time, the output voltage of 0 UTPUT-L becomes a low voltage value (L). Furthermore, when the operation knob 2 is pushed in and the state shown in FIG. 7 is reached, both the first plastic magnet 3a and the second plastic magnet 3b are opposed to the first Hall element 4a and the second Hall element 4b, respectively. Then, the most separated state is formed, and the magnetism applied to each Hall element 4 becomes a weak field state. Accordingly, since the resistance value of the two Hall elements 4 becomes a high resistance value, the output voltages at the output terminals OUTPUT-L and 0 U T P U T-R become both high values (双方). The change in the output voltage is transmitted to the determination logic unit 5. Based on the output voltage, the determination logic unit 5 determines whether to blink or turn off any one of the left and right signal lights included in the two-wheeled vehicle based on the specified determination logic, and blinks or turns off the specified signal light based on the determination result. That is, as shown in FIG. 8, in response to the output voltage from the Hall element 4, it is determined whether or not the left and right signal lights are blinked or the blinking of the signal lights is canceled, and a designated circuit is constituted or worn based on the above results. According to the same figure, when the operation knob 2 is shaken to the left, the signal light on the left blinks, and when the operation knob 2 is shaken to the right, the signal light on the right is blinked, and if the operation knob 2 is pushed in and operated To cancel the blinking of the signal light. In addition, the operation knob 2 maintains the front state in the middle position, so even if the operation knob 2 returns to the middle position after the operation, the operation-based blinking or light off can be maintained. In addition, as shown in FIG. 3, in the circuit of the substrate 6, the resistance elements R1 to R3 12 3 丨 2 / Invention ftf (Supplement) / 93-03 / 93 丨 00525 1230387 are connected to the Hall element 4 a side, At the same time, the resistive elements R 4 to R 6 are connected to the Hall element 4 b side. With the above resistance element, the output voltage of each Hall element 4 can be limited to a specified range. For example, when the voltage of the power supply V cc is 5 V, the output voltage is limited to 0.5 V to 4.5 V. In the range. As a result, when the electric wire (not shown) is disconnected from the terminal 7, or when the power and output terminals are disconnected, the output voltage becomes 0V, and when the GND is disconnected, the output voltage becomes 5 V (power V When the voltage of cc is 5 V), the output voltage is outside the range of 0.5 V to 4.5 V as described above. In this case, abnormality such as disconnection can be confirmed. According to the first embodiment described above, the two Hall elements 4 (the first Hall element 4 a and the second Hall element 4 b) can perform the blinking operation of the left side signal light, the blinking operation of the right side signal, and the cancel operation. 3 operations. Therefore, it is possible to reduce the manufacturing cost of the turn signal switch as compared with the case where the three magnetic detection units are required to separately detect the three operations of the operation knob 2. Next, a turn signal switch according to a second embodiment of the present invention will be described. In addition, the same components as those in the first embodiment are assigned the same reference numerals, and detailed descriptions thereof are omitted. The turn signal switch of this embodiment is the same as that of the first embodiment, and is installed near the handle of the steering handle of the two-wheeled vehicle, and is an operator who can switch the blinking or extinguishing of the signal light provided by the two-wheeled vehicle, as shown in FIGS. 9 to 1 As shown in Figure 2, it is mainly composed of a box 1, an operation knob 2, a plastic magnet 3, an angle sensor 1 as a magnetic detection section 2, a determination logic section 5, and a shield plate 14. The box 1 is the same as the first embodiment, and is the first box 1 that connects the interior 13 as shown in FIG. 10 2/2 / Description of the Invention (Supplement) / 93-03 / 93100525 1230387 forming the swing axis 1 C and the swing space S a; and a second box 1 b having a substrate 6 having an angle sensor 12 built therein, and the substrate 6 is encapsulated by a resin. Further, an adjustment degree supply mechanism 8 is formed in the swing space S, and the steel balls 11 using the elastic force of the coil spring 10 are formed to be slidable. Thereby, the degree of adjustment during shaking operation can be obtained, and at the same time, when the operator's finger leaves the operation knob 2, the operation knob 2 often returns to the middle position. The operation knob 2 is formed so that the rocking shaft 1 c can be pivoted from the middle position to the left and right sides at the center. The position corresponding to the rocking shaft 1 c is formed so as to protrude beyond the second end of the rocking shaft 1 c Plastic magnet 3 of the box 1 b. Thereby, when the operation knob 2 is operated by shaking, the plastic magnet 3 formed at the center of the shaking is rotated. In addition, a magnetically shielded shield plate 14 is disposed on the side of the plastic magnet 3 to limit the range that the magnetism of the plastic magnet 3 can involve. That is, the side surface of the plastic magnet 3 is surrounded by the shield plate 14, so its magnetic properties are limited to the position facing the plastic magnet 3. An angle sensor 12 is fixed to a position facing the plastic magnet 3 on the substrate 6. The angle sensor 12 varies the output voltage by changing the resistance value in accordance with the direction of the magnetic field lines released by the magnet. When the plastic magnet 3 is rotated with the rocking operation of the operation knob 2, the plastic line 3 responds to the magnetic field lines. The direction changes and the resistance value changes. As shown in FIG. 11, the above-mentioned angle sensor 12 is connected to the amplifier 13 provided on the substrate 6. After the output voltage of the angle sensor 12 is amplified through the amplifier 13, the amplified value is Transfer to decision logic 5. The output voltage amplified by enlarging 14 3 丨 2 / Invention Specification (Supplement) / 93-03 / 93 100525 1230387 device 1 3 is set to the output waveform as shown in Figure 13 and is located at the operation knob 2 In the middle position, it becomes point A, and it becomes point B when the rocking operation is performed to the left, point C when the rocking operation is performed to the right, and point D when the operation knob 2 is pushed in. In particular, when the plastic magnet 3 moves downwards with the push-in operation of the operation knob 2, the plastic magnet 3 leaves the angle sensor 12 and becomes misaligned. Therefore, by the action of the shield plate 14 So that its magnetic does not apply to the angle sensor 12. Thereby, when the operation knob 2 is pushed in and operated, it becomes the minimum output voltage (in the case of this embodiment, it is about 0.5 V as shown in FIG. 13). Based on the output voltage of the angle sensor 12, the determination logic unit 5 determines whether to blink or turn off any one of the left and right signal lights provided by the two-wheeled vehicle based on the specified determination logic, and based on the determination result, the specified signal light blinks or Off. That is, as shown in FIG. 14, in response to the output voltage from the angle sensor 12, it is determined whether to blink or cancel the blinking of either of the left and right signal lamps, and based on the above results, a specified circuit is constructed or worn. According to the same figure, if the operation knob 2 is shaken to the left, the signal light on the left blinks, and if the operation knob 2 is shaken to the right, the signal light on the right 闪烁 blinks, and if the operation knob 2 is pushed in, The blinking of the signal light is canceled. In addition, the operation knob 2 maintains the front state at the middle position, so even if the operation knob 2 returns to the middle position after the operation, the operation-based blinking or light-off can be maintained. According to the second embodiment described above, one angle sensor 12 can be used to perform 15 3 12 / Inventive Note (Supplement) / 93-03 / 93 丨 00525 1230387 The blinking operation of the left side signal light, and the right side signal light 3 operations of flashing operation and cancel operation. Therefore, it is possible to reduce the manufacturing cost of the turn signal switch as compared with the case where three or two magnetic detection sections are provided. In addition, by placing a magnetically shielded shield plate 14 on the side of the plastic magnet 3, the magnetic force from the plastic magnet can be surely worn when the operation knob 2 is pushed in. By performing the determination by the determination logic section more accurately when canceling the operation, the blinking of the signal light can be more reliably canceled. The first embodiment and the second embodiment have been described above, but the present invention is not limited to these. For example, instead of a plastic magnet, a permanent magnet may be connected to the operation knob, as long as it can respond to the magnet accompanying the operation knob. If the moving magnetic changes the output voltage, you can use a magnetic detector that is different from the Hall element and the angle sensor. In addition, the determination by the determination logic unit is not limited to the above method of the above embodiment, and an arbitrary design can be made. In addition, although the steering signal switch mounted on the steering handle of the two-wheeled vehicle is shown in any case in this embodiment, it can also be applied to other snow steering wheels, three-wheeled, or four-wheeled carts with steering handles. vehicle. C Invention effect) According to the invention of the first scope of the patent application as described above, the magnet is moved based on the rocking operation and the push-in operation of the operation knob, and the required signal light flickers in response to the magnetic change accompanying the movement, and simultaneously The blinking is canceled, so the signal lamp can be operated by a non-contact method without using a contact. Therefore, it is possible to avoid a reduction in life due to abrasion of the contacts, and at the same time, it is possible to surely avoid poor electrical contact caused by water leakage in the case. 16 3 12 / Invention 叨 · (Supplement) / 93-03 / 93 100525 1230387 According to the scope of the patent application, there are 2 operations: the flashing operation of the left signal lamp and the 3 operations of canceling the operation. The manufacturing cost of 3 magnetic inspections due to 3 operations of the button. The output voltage of the magnetic detection unit is limited according to item 3 of the patent application. This is an abnormality when the output voltage exceeds its range. In addition, according to the patent application scope, the sensor can perform three magnetic detections on the left side of the signal flashing operation and cancel operation. Compared with the patent application scope, the fifth shielding plate can be reduced to be placed on the side of the magnet.戠 Stop the wave and the angle sensor to confirm the blinking of the decision logic signal when canceling the operation.

Compared with the invention that requires a separate detection operation rotation detection unit, the invention that can turn on the turn signal can be reduced because it has The fourth invention can be used to connect the resistance element within the specified range as a disconnection due to the situation. The flashing operation at one angle and the operation of the signal light on the right are used. Therefore, the manufacturing cost is the same as having three or two turn signal switches. According to the invention, the magnetic operation of the plastic screen magnet can be confirmed by pressing the operation knob of the cut-off magnetic screen, so that the magnetism of the plastic part can be determined, and the correction section can be judged more accurately, and the figure of the turn signal switch of the first embodiment can be canceled more reliably. -A cross-sectional view taken on line Π.
