The two positioning portions 922 respectively correspond to and are embedded in the positioning grooves 81 at the corresponding positions on the front housing 80.
再請參閱圖9所示，該轉盤90後盤面上的凹部905是用來容置該接點彈片91，而該凹部905表面以等角度形成有三支固定柱906，用以固定該接點彈片91，該接點彈片91主要係於一內環的外周緣以等角度向外延伸形成三個凸部911，各凸部911上分別形成一固定孔912，以對應固設在凹部905內的固定柱906上，又各凸部911在對應的一側邊上分別沿內環的外徑延伸形成一接觸臂913，各接觸臂913的自由端分別朝後殼70方向彎折以形成一接觸部914，該三個接觸部914將對應接觸於後殼70背部701上第一至第三導電部71~73。Referring to FIG. 9 again, the concave portion 905 on the rear surface of the turntable 90 is used for accommodating the contact elastic piece 91, and the surface of the concave portion 905 is formed with three fixing posts 906 at equal angles for fixing the contact elastic piece. 91.

In the portion 914, the three contact portions 914 will correspond to the first to third conductive portions 71-73 on the back 701 of the rear case 70.
前述編碼器經組合後是如圖10所示，至於其工作原理是如以下所述：前述轉盤90露出在前、後殼80,70外的軸套903，可方便在其軸孔901內套接一轉軸，該轉軸可能被以摩擦方式帶動旋轉，進而使轉盤90跟著旋轉。The foregoing encoders are combined as shown in FIG. 10, and the working principle is as follows: the aforementioned turntable 90 is exposed to the sleeve 903 outside the front and rear casings 80, 70, and can be conveniently placed in the shaft hole 901 thereof. Following a rotating shaft, the rotating shaft may be frictionally rotated to rotate the turntable 90.
在轉盤90旋轉時，其前盤面上所設定位彈片92因定位部922嵌入前殼80上的定位槽82，因此將對轉盤90旋轉形成微干涉，而定位部922進出各相鄰定位槽82時，即產生一刻度感。When the turntable 90 rotates, the position spring 92 of the front disk surface is inserted into the positioning groove 82 of the front case 80 by the positioning portion 922, so that the turntable 90 is rotated to form a micro interference, and the positioning portion 922 enters and exits each adjacent positioning groove 82. At that time, a sense of scale is produced.
又轉盤90旋轉的同時，其後盤面上所設的接點彈片91也跟著旋轉，該接點彈片91上的三個接觸部914將隨著轉盤90的正反轉，依序使後殼70上的第一及第二導電部71,72、第二及第三導電部72,73、第三及第一導電部73,71先後導通，藉此可在第一至第三接腳710~730上產生對應的導通狀態，以方便判斷轉軸的旋轉方向與旋轉量。At the same time as the turntable 90 rotates, the contact spring piece 91 disposed on the rear surface of the disk also rotates, and the three contact portions 914 on the contact spring piece 91 will sequentially rotate the rear case 70 along with the turntable 90. The first and second conductive portions 71, 72, the second and third conductive portions 72, 73, and the third and first conductive portions 73, 71 are sequentially turned on, thereby being accessible to the first to third pins 710~ A corresponding conduction state is generated on the 730 to facilitate determining the rotation direction and the rotation amount of the rotation shaft.
前述編碼器雖可提供座標編碼功能，但就構造上及組裝方式仍有可待檢討之處：如前揭所述，前述編碼器上的轉盤90是以卡合方式分別在前、後盤面上結合定位彈片92及接點彈片91，此種結合方式必須依賴人工方式進行組裝，無法實現自動化組裝，且由於編碼器本身體積很小，內部的轉盤90及接點彈片91、定位彈片92更小，人工組裝時很難提高速度，造成裝配效率低，而人工成本相對提高。Although the aforementioned encoder can provide the coordinate coding function, there are still some areas to be reviewed in terms of construction and assembly: as described above, the turntable 90 on the aforementioned encoder is respectively engaged on the front and rear panels. In combination with the positioning elastic piece 92 and the contact elastic piece 91, the combination manner must be assembled by manual means, and automatic assembly cannot be realized, and since the encoder itself is small in size, the inner turntable 90 and the contact spring piece 91 and the positioning elastic piece 92 are smaller. It is difficult to increase the speed during manual assembly, resulting in low assembly efficiency and relatively high labor costs.
由上述可知，既有編碼器仍有進一步改良其構造的空間。As can be seen from the above, there is still room for the encoder to further improve its construction.
因此本發明主要目的在提供一種輸入裝置的模組化編碼器，其內部的主要元件採模組化設計，使其構造得以簡化，且可實現自動化組裝，而大幅提高裝配效率，並相對降低成本。Therefore, the main object of the present invention is to provide a modular encoder for an input device, wherein the main components of the module are modularized, the structure thereof is simplified, and the assembly can be automated, thereby greatly improving assembly efficiency and relatively reducing costs. .

由上述兩波形圖可以看出，轉盤30以順時針或逆時針方向旋轉時，由第二、第三接觸端子42,43上讀到的直流脈波訊號適為相反，因此可藉此判斷轉盤30的旋轉方向。It can be seen from the above two waveform diagrams that when the turntable 30 is rotated in the clockwise or counterclockwise direction, the DC pulse signals read by the second and third contact terminals 42 and 43 are opposite, so that the turntable can be judged by this. The direction of rotation of 30.
仍請參閱圖1所示，第一接觸端子41進一步延伸形成有一定位臂411，該定位臂411與第一接觸部410位於同一方向，又定位臂411具有一長度，其自由端形成有一朝轉盤方向突出的定位部412，該定位部412是對應且嵌入轉盤30內盤面周邊的其中一凹槽302內，並可移至其他凹槽302內，一旦定位臂411的定位部412嵌入轉盤30的凹槽302，將對轉盤30的轉動形成微干涉，但由於各凹槽302底部係呈圓弧狀，故在轉盤30轉動時，定位部412可以輕易地離開凹槽302，並進入相鄰其他的凹槽302內，而在進出凹槽302之間即產生一刻度感。Referring to FIG. 1 , the first contact terminal 41 further extends to form a positioning arm 411 . The positioning arm 411 is in the same direction as the first contact portion 410 , and the positioning arm 411 has a length, and the free end is formed with a facing end. a positioning portion 412 protruding in the direction, which is corresponding to and embedded in one of the grooves 302 in the periphery of the disk surface of the turntable 30, and can be moved into the other groove 302, once the positioning portion 412 of the positioning arm 411 is embedded in the turntable 30 The groove 302 will form a micro interference with the rotation of the turntable 30. However, since the bottom of each groove 302 has an arc shape, when the turntable 30 rotates, the positioning portion 412 can easily leave the groove 302 and enter adjacent ones. Within the recess 302, a sense of scale is created between the access recess 302.
關於前述接觸定位件40的構成方式，可在絕緣座44上形成數個插槽，供第一至第三接觸端子41~43分別穿設後，以構成一接觸定位件40；除上述方式外，亦可採用以下的方式構成：請參閱圖6所示，該第一至第三接觸端子41~43是成組形成在一料帶400上(如圖6右端所示)，接著可以連同料帶400進入射出成型機，以包射形成同時包覆第一至第三接觸端子41~43的絕緣座44(如圖6中央所示)，最後則將接觸定位件40自料帶400上裁切即可。Regarding the configuration of the contact positioning member 40, a plurality of slots may be formed in the insulating base 44 for the first to third contact terminals 41-43 to be respectively disposed to form a contact positioning member 40; It can also be configured in the following manner: Referring to FIG. 6, the first to third contact terminals 41-43 are formed in groups on a tape 400 (as shown in the right end of FIG. 6), and then can be fed together. The belt 400 enters the injection molding machine to form an insulating seat 44 covering the first to third contact terminals 41 to 43 at the same time (as shown in the center of FIG. 6), and finally, the contact positioning member 40 is cut from the strip 400. Cut it.
前述第一、第二外殼10,20及轉盤30、接觸定位件40經組合後係如圖7所示。The first and second outer casings 10, 20 and the turntable 30 and the contact positioning member 40 are combined as shown in FIG.
由上述可知，本發明的編碼器利用轉盤及接觸定位件上的特殊構造得以同時產生編碼功能及刻度感，因而大幅簡化了編碼器的構造；且由於簡化構造，故更進一步將元件模組化，以實現自動化組裝，進而提高組裝效率，相對降低成本。It can be seen from the above that the encoder of the present invention utilizes a special structure on the turntable and the contact positioning member to simultaneously generate the encoding function and the scale feeling, thereby greatly simplifying the structure of the encoder; and further simplifying the components due to the simplified structure. In order to achieve automated assembly, thereby improving assembly efficiency and relatively reducing costs.
