[專利文獻1]日本專利特開2001－5545號公報、圖23[Patent Document 1] Japanese Patent Laid-Open Publication No. 2001-5545, Fig. 23
然而，於上述先前的多方向輸入裝置中，必須將霍爾元件安裝於搭載有裝置本體之基板上之特定位置。特別對於該多向輸出裝置，在因轉動構件之轉動中伴隨的磁鐵之旋轉而變化的霍爾元件之輸出平衡之作用下，檢測在對操作軸之操作方向及操作量，故要求較高的位置精度。因而，存在將該等霍爾元件安裝於基板上時的作業性差的問題。However, in the above-described conventional multi-directional input device, it is necessary to mount the Hall element at a specific position on the substrate on which the device body is mounted. In particular, in the multi-directional output device, the output direction and the operation amount of the operation shaft are detected under the action of the balance of the output of the Hall element which is changed by the rotation of the magnet accompanying the rotation of the rotating member, so that a high requirement is required. Positional accuracy. Therefore, there is a problem in that the workability when the Hall elements are mounted on the substrate is poor.

In this case, since the holding member can be returned to the initial position by the elastic member, the first and second driving members coupled to the holder can be returned to the initial position, whereby the operating member can be returned to the initial position. By disposing the elastic member between the housing and the rotation detecting mechanism, the configuration inside the housing can be simplified, and the operating member can be returned to the initial position.
例如，於上述多方向輸入裝置中，上述磁性檢測元件係由GMR(Giant Magnet Resistance，巨磁阻)元件所構成。如此由GMR元件構成磁性檢測元件，從而能夠以例如較磁性檢測元件使用霍爾元件時之解析度高的解析度來檢測對操作構件之操作量。For example, in the multidirectional input device described above, the magnetic detecting element is constituted by a GMR (Giant Magnet Resistance) element. By configuring the magnetic detecting element by the GMR element as described above, it is possible to detect the amount of operation of the operating member with, for example, a higher resolution than when the magnetic detecting element uses the Hall element.

Accordingly, the button portion 701 of the switching element 7 is pressed by the arm portion 505 of the second driving member 5. Then, the pressing operation is detected by the switching element 7, and a signal output corresponding thereto is performed to a control device (not shown).
如此，根據本實施形態之多方向輸入裝置1，以可旋轉之方式收容有固持件602，其連結於第1驅動構件4及第2驅動構件5，並保持有磁鐵601，並且將GMR元件605定位於特定位置，於此狀態下，從殼體2之外側安裝罩603。因而，只要將罩603安裝於殼體2上，即可將第1驅動構件4及第2驅動構件5與轉動檢測機構6a和6b加以連結，並且可將磁鐵601與GMR元件605配置於所需之位置。其結果能夠提供一種多方向輸入裝置1，其可確保構成磁性感測器之磁鐵601與GMR元件605之位置精度，並且將磁性感測器組裝入往裝置本體時之作業性優異。As described above, according to the multidirectional input device 1 of the present embodiment, the holder 602 is rotatably accommodated, and is coupled to the first driving member 4 and the second driving member 5, and holds the magnet 601, and the GMR element 605 is held. The cover 603 is attached from the outer side of the casing 2 in a specific position. Therefore, by attaching the cover 603 to the casing 2, the first drive member 4 and the second drive member 5 can be coupled to the rotation detecting mechanisms 6a and 6b, and the magnet 601 and the GMR element 605 can be disposed at a desired position. The location. As a result, it is possible to provide a multi-directional input device 1 which can ensure the positional accuracy of the magnet 601 and the GMR element 605 constituting the magnetic sensor, and is excellent in workability when the magnetic sensor unit is mounted to the apparatus body.
特別於本實施形態之多方向輸入裝置1中，在罩603上設置有一對卡止片603e，該一對卡止片插入到形成於殼體2上之縫隙部中。藉此，只要將一對卡止片603e插入到殼體2之縫隙部中，即可將罩603卡止於殼體2上，而由於轉動 檢測機構6a和6b本身被安裝於殼體2上，故可簡化將磁性感測器組裝入往裝置本體時之作業。In the multi-directional input device 1 of the present embodiment, a pair of locking pieces 603e are provided in the cover 603, and the pair of locking pieces are inserted into the slit portion formed in the casing 2. Thereby, as long as the pair of locking pieces 603e are inserted into the slit portion of the casing 2, the cover 603 can be locked to the casing 2 due to the rotation. The detecting mechanisms 6a and 6b are themselves mounted on the casing 2, so that the operation of loading the magnetic sensor group into the apparatus body can be simplified.
又，本實施形態之多方向輸入裝置1中，在罩603上設置有插入片603d，該插入片插入到安裝有GMR元件605之基板604上所形成之孔604a中。藉此，只要將插入片603d插入到基板604之孔604a中，即可決定罩603上的GMR元件605之位置。另一方面，藉由將保持有磁鐵601之固持件602加以收容，而決定罩603上的GMR元件605之位置，因此可將磁鐵601與GMR元件605配置於所需之位置。Further, in the multidirectional input device 1 of the present embodiment, the cover 603 is provided with an insertion piece 603d which is inserted into the hole 604a formed in the substrate 604 on which the GMR element 605 is attached. Thereby, the position of the GMR element 605 on the cover 603 can be determined by inserting the insertion piece 603d into the hole 604a of the substrate 604. On the other hand, since the position of the GMR element 605 on the cover 603 is determined by accommodating the holder 602 holding the magnet 601, the magnet 601 and the GMR element 605 can be placed at a desired position.
再有，本實施形態之多方向輸入裝置1中，採用GMR元件605作為磁性檢測元件。由於如此採用GMR元件605作為磁性檢測元件，因而例如能夠以較採用霍爾元件作為磁性檢測元件時之解析度高的解析度，來檢測對操作軸3之操作量。Further, in the multidirectional input device 1 of the present embodiment, the GMR element 605 is used as the magnetic detecting element. Since the GMR element 605 is used as the magnetic detecting element in this manner, for example, the amount of operation on the operating shaft 3 can be detected with a higher resolution than when the Hall element is used as the magnetic detecting element.
再者，本發明並非限定於上述實施形態，可進行各種變更實施。於上述實施形態中，關於附圖所示之大小和形狀等，並非限定於此，在發揮本發明之效果之範圍內可適宜變更。此外，只要不脫離本發明目的之範圍，則可適宜變更而實施。Furthermore, the present invention is not limited to the above embodiment, and various modifications can be made. In the above-described embodiments, the size, shape, and the like shown in the drawings are not limited thereto, and can be appropriately changed within the range in which the effects of the present invention are exerted. Further, the invention can be carried out as appropriate without departing from the scope of the object of the invention.
例如，於上述實施形態中，僅顯示如下情況：轉動檢測機構6a和6b具有對第1驅動構件4及第2驅動構件5之轉動進行檢測之功能，但轉動檢測機構6a和6b之構成並非限定於此，可進行適當變更。例如，除了檢測第1驅動構件4及第2驅動構件5之轉動之功能以外，亦可附加使操作軸3復位 到初始位置之功能。For example, in the above-described embodiment, only the rotation detecting means 6a and 6b have a function of detecting the rotation of the first driving member 4 and the second driving member 5, but the configuration of the rotation detecting mechanisms 6a and 6b is not limited. Here, it can be changed as appropriate. For example, in addition to the function of detecting the rotation of the first drive member 4 and the second drive member 5, the operation shaft 3 may be additionally reset. The function to the initial position.
圖5係於上述實施形態之多方向輸入裝置1中，附加有使操作軸3復位到初始位置之功能時的轉動檢測機構6a(6b)之放大圖。當附加使操作軸3復位到初始位置之功能時，如圖5所示，例如考慮在較固持件602更靠近殼體2側之位置處，配設作為彈性構件之賦能構件607，並以使固持件602返回到初始位置之方式進行賦能。於該情形時，對應於對固持件602賦予之賦能力，連結於固持件602之第1驅動構件4(第2驅動構件5)返回到初始位置。藉此，連結於第1驅動構件4(第2驅動構件5)之操作軸3復位到初始位置。Fig. 5 is an enlarged view of the rotation detecting mechanism 6a (6b) when the multi-directional input device 1 of the above embodiment is added with a function of resetting the operating shaft 3 to the initial position. When the function of resetting the operating shaft 3 to the initial position is added, as shown in FIG. 5, for example, it is considered that the energizing member 607 as an elastic member is disposed at a position closer to the side of the housing 2 than the holding member 602, and The energization is performed in such a manner that the holder 602 is returned to the initial position. In this case, the first driving member 4 (second driving member 5) coupled to the holder 602 is returned to the initial position in accordance with the ability to impart the holding member 602. Thereby, the operation shaft 3 connected to the first drive member 4 (second drive member 5) is returned to the initial position.
賦能構件607例如係由磷青銅等彈性材料形成，具有設置成與罩603對應之大致矩形狀之平板部607a，於該平板部607a之中央部上，形成有圓形狀之開口部607b。並且，於該開口部607b之周圍，形成具有半圓弧形狀之一對板簧部607c、607d。板簧部607c向圖5所示之下方開口，另一方面，板簧部607d向該圖所示之上方開口，並且利用其兩端部而與平板部607a連結。The energizing member 607 is formed of, for example, an elastic material such as phosphor bronze, and has a substantially rectangular flat plate portion 607a corresponding to the cover 603, and a circular opening portion 607b is formed in a central portion of the flat plate portion 607a. Further, one of the semicircular arc shapes and the leaf spring portions 607c and 607d is formed around the opening 607b. The leaf spring portion 607c is opened to the lower side shown in FIG. 5, and the leaf spring portion 607d is opened upward in the figure, and is connected to the flat plate portion 607a by both end portions thereof.
在板簧部607c之中央部上，於固持件602側形成有凸狀之突起部607e。另一方面，在固持件602之圖5所示之上端部上，設置有收容有突起部607e之收容部602b。收容部602b設置於在第1驅動構件4(第2驅動構件5)未轉動之狀態下收容有突起部607e之位置處。另外，在賦能構件607之角部附近，在與罩603之突出片603c相對應之位置處，形成有複數個孔607f。A convex protrusion 607e is formed on the holder 602 side in the central portion of the leaf spring portion 607c. On the other hand, the upper end portion of the holder 602 shown in FIG. 5 is provided with a housing portion 602b in which the protrusion portion 607e is accommodated. The accommodating portion 602b is provided at a position where the protruding portion 607e is accommodated in a state where the first driving member 4 (the second driving member 5) is not rotated. Further, in the vicinity of the corner portion of the energizing member 607, a plurality of holes 607f are formed at positions corresponding to the protruding pieces 603c of the cover 603.
在具備上述賦能構件607之情況下，若第1驅動構件4(第2驅動構件5)對應於操作軸3之偏斜動作而轉動從而固持件602旋轉時，則突起部607e對應於固持件602之旋轉而移動。此時，對固持件602賦予欲使固持件602返回到初始位置之板簧607c之賦能力。因而，若操作軸3從偏斜動作中解放，則隨著固持件602返回到初始位置，第1驅動構件4(第2驅動構件5)向初始位置返回。藉此，連結於第1驅動構件4(第2驅動構件5)之操作軸3復位到初始位置。When the energizing member 607 is provided, when the first driving member 4 (second driving member 5) rotates in accordance with the skewing operation of the operating shaft 3, and the holding member 602 rotates, the protruding portion 607e corresponds to the holding member. The rotation of 602 moves. At this time, the holding member 602 is given the ability to impart the return of the holder 602 to the initial position of the leaf spring 607c. Therefore, when the operation shaft 3 is released from the deflection operation, the first drive member 4 (second drive member 5) returns to the initial position as the holder 602 returns to the initial position. Thereby, the operation shaft 3 connected to the first drive member 4 (second drive member 5) is returned to the initial position.
如此，當對轉動檢測機構6a(6b)附加有使操作軸3復位到初始位置之功能時，可利用賦能構件607使固持件602復位到初始位置，因此可將與之連結之第1驅動構件4(第2驅動構件5)復位到初始位置，隨此可將操作軸3復位到初始位置。藉由將上述賦能構件607配置在殼體2與轉動檢測機構6a(6b)之間，可簡化殼體2內之構成，並且可使操作軸3復位到初始位置。Thus, when the rotation detecting mechanism 6a (6b) has a function of resetting the operating shaft 3 to the initial position, the energizing member 607 can be used to reset the holding member 602 to the initial position, so that the first driving can be connected thereto. The member 4 (second drive member 5) is reset to the initial position, whereby the operating shaft 3 can be reset to the initial position. By disposing the energizing member 607 between the casing 2 and the rotation detecting mechanism 6a (6b), the configuration in the casing 2 can be simplified, and the operating shaft 3 can be returned to the initial position.
