Description

本発明は、多方向入力装置に関し、特に、操作部材に対する周囲の任意方向への操作に応じて各種信号の入力を行う多方向入力装置に関する。   The present invention relates to a multidirectional input device, and more particularly to a multidirectional input device that inputs various signals in response to an operation in an arbitrary surrounding direction with respect to an operation member.

従来から、周囲の任意方向への操作が可能な操作軸を備え、この操作軸に対する操作方向及び操作量に応じて信号出力を行う多方向入力装置が知られている。このような多方向入力装置として、例えば、操作軸に対する操作方向及び操作量を、操作軸に対する操作に応じて回動する回動部材に連結された磁石と、この磁石に組み合わされた一対のホール素子とからなる磁気センサで検出し、信号出力を行うものが提案されている（例えば、特許文献１参照）。
特開２００１−５５４５号公報、図２３ 2. Description of the Related Art Conventionally, a multi-directional input device that includes an operation shaft that can be operated in an arbitrary surrounding direction and outputs a signal according to an operation direction and an operation amount with respect to the operation shaft is known. As such a multi-directional input device, for example, a magnet connected to a rotating member that rotates an operation direction and an operation amount with respect to the operation shaft according to an operation with respect to the operation shaft, and a pair of holes combined with the magnet A device that detects a signal by a magnetic sensor including an element and outputs a signal has been proposed (for example, see Patent Document 1).
Japanese Patent Laid-Open No. 2001-5545, FIG.

しかしながら、上述した従来の多方向入力装置においては、ホール素子を、装置本体が搭載される基板上の所定位置に実装しなければならない。特に、当該多方向入力装置においては、回動部材の回動に伴う磁石の回転により変化するホール素子の出力バランスによって操作軸に対する操作方向及び操作量を検出するため、高い位置精度が要求される。このため、これらのホール素子を基板上に実装する際における作業性が悪いという問題がある。   However, in the conventional multi-directional input device described above, the Hall element must be mounted at a predetermined position on the substrate on which the device main body is mounted. In particular, in the multi-directional input device, high position accuracy is required because the operation direction and the operation amount with respect to the operation axis are detected by the output balance of the Hall element that changes due to the rotation of the magnet accompanying the rotation of the rotation member. . For this reason, there exists a problem that workability | operativity at the time of mounting these Hall elements on a board | substrate is bad.

本発明はかかる問題点に鑑みてなされたものであり、磁気センサを構成する磁石と磁気検出素子との位置精度を確保しつつ、装置本体に磁気センサを組み込む際の作業性に優れた多方向入力装置を提供することを目的とする。   The present invention has been made in view of such a problem, and has ensured the positional accuracy between the magnet and the magnetic detection element constituting the magnetic sensor, and has excellent workability when incorporating the magnetic sensor into the apparatus main body. An object is to provide an input device.

本発明の多方向入力装置は、内部に空間を有するケースと、前記ケースから一部を露出し操作者による操作を受け付ける操作部材と、前記ケース内に互いに直交する方向に配設されると共に前記操作部材に対する傾動操作に応じて回動する第１及び第２の駆動部材と、前記第１及び第２の駆動部材の回動を検出する回動検出機構とを具備し、前記回動検出機構は、前記第１及び第２の駆動部材に連結されると共に磁石を保持するホルダと、前記ホルダに保持された前記磁石と対向配置される磁気検出素子と、前記ホルダを回転可能に収容すると共に前記磁気検出素子を所定位置に位置決めした状態で前記ケースの外側から取り付けられるカバーとを有することを特徴とする。   The multidirectional input device of the present invention includes a case having a space inside, an operation member that exposes a part of the case and receives an operation by an operator, and is disposed in a direction orthogonal to each other in the case. The rotation detection mechanism includes first and second drive members that rotate according to a tilting operation with respect to the operation member, and a rotation detection mechanism that detects rotation of the first and second drive members. Includes a holder connected to the first and second driving members and holding a magnet, a magnetic detection element disposed opposite to the magnet held by the holder, and rotatably receiving the holder. And a cover attached from the outside of the case in a state where the magnetic detection element is positioned at a predetermined position.

上記多方向入力装置によれば、第１及び第２の駆動部材に連結され、磁石を保持するホルダを回転可能に収容すると共に、磁気検出素子を所定位置に位置決めした状態でカバーがケースの外側から取り付けられる。このため、カバーを取り付けるだけで第１及び第２の駆動部材と回動検出機構とを連結すると共に、磁石と磁気検出素子とを所望の位置に配置することができるので、磁気センサを構成する磁石と磁気検出素子との位置精度を確保しつつ、装置本体に磁気センサを組み込む際の作業性に優れた多方向入力装置を提供することが可能となる。   According to the multidirectional input device, the cover is connected to the first and second drive members, rotatably accommodates the holder that holds the magnet, and the cover is located outside the case with the magnetic detection element positioned at a predetermined position. It is attached from. For this reason, the first and second drive members and the rotation detection mechanism can be connected to each other simply by attaching the cover, and the magnet and the magnetic detection element can be arranged at desired positions, so that the magnetic sensor is configured. It is possible to provide a multidirectional input device that is excellent in workability when the magnetic sensor is incorporated into the apparatus main body while ensuring the positional accuracy between the magnet and the magnetic detection element.

上記多方向入力装置において、前記カバーは、前記ケースに形成された開口部に挿入される係止片を有することが好ましい。この場合には、係止片をケースの開口部に挿入するだけでカバーがケースに係止されることから、回動検出機構自体がケースに取り付けられるので、装置本体に磁気センサを組み込む際の作業を簡素化することが可能となる。   In the multidirectional input device, it is preferable that the cover has a locking piece inserted into an opening formed in the case. In this case, since the cover is locked to the case simply by inserting the locking piece into the opening of the case, the rotation detection mechanism itself is attached to the case. The work can be simplified.

また、上記多方向入力装置において、前記カバーは、前記磁気検出素子が実装された基板に形成される孔に挿入される挿入片を有することが好ましい。この場合には、挿入片を磁気検出素子が実装された基板の孔に挿入するだけで、カバーにおける磁気検出素子の位置を決定することができる。一方、磁石を保持したホルダを収容することで、カバーにおける磁気検出素子の位置が決定されるので、磁石と磁気検出素子とを所望の位置に配置することが可能となる。   In the multidirectional input device, it is preferable that the cover has an insertion piece that is inserted into a hole formed in a substrate on which the magnetic detection element is mounted. In this case, the position of the magnetic detection element in the cover can be determined simply by inserting the insertion piece into the hole of the substrate on which the magnetic detection element is mounted. On the other hand, since the position of the magnetic detection element in the cover is determined by accommodating the holder holding the magnet, the magnet and the magnetic detection element can be arranged at a desired position.

なお、上記多方向入力装置においては、前記ケースと前記回動検出機構との間に、前記ホルダを初期位置に復帰させるための弾性部材を配設するようにしても良い。この場合には、弾性部材によりホルダを初期位置に復帰させることができることから、これに連結された第１及び第２の駆動部材を初期位置に復帰させることができ、これに伴って操作部材を初期位置に復帰させることができる。このような弾性部材をケースと回動検出機構との間に配置することで、ケース内の構成を簡素化しつつ、操作部材を初期位置に復帰させることが可能となる。   In the multidirectional input device, an elastic member for returning the holder to an initial position may be disposed between the case and the rotation detection mechanism. In this case, since the holder can be returned to the initial position by the elastic member, the first and second driving members connected to the holder can be returned to the initial position. It can be returned to the initial position. By disposing such an elastic member between the case and the rotation detection mechanism, it is possible to return the operation member to the initial position while simplifying the configuration in the case.

例えば、上記多方向入力装置において、前記磁気検出素子は、ＧＭＲ素子で構成される。このように磁気検出素子をＧＭＲ素子で構成することにより、例えば、磁気検出素子にホール素子を用いた場合よりも高い分解能で操作部材に対する操作量を検出することが可能となる。   For example, in the multidirectional input device, the magnetic detection element is configured by a GMR element. By configuring the magnetic detection element with a GMR element in this manner, for example, it becomes possible to detect the operation amount with respect to the operation member with higher resolution than when a Hall element is used as the magnetic detection element.

本発明によれば、カバーを取り付けるだけで第１及び第２の駆動部材と回動検出機構とを連結すると共に、磁石と磁気検出素子とを所望の位置に配置することができるので、磁気センサを構成する磁石と磁気検出素子との位置精度を確保しつつ、装置本体に磁気センサを組み込む際の作業性に優れた多方向入力装置を提供することが可能となる。   According to the present invention, the first and second drive members and the rotation detection mechanism can be connected to each other by simply attaching the cover, and the magnet and the magnetic detection element can be arranged at desired positions. It is possible to provide a multidirectional input device that is excellent in workability when the magnetic sensor is incorporated into the apparatus main body while ensuring the positional accuracy between the magnet and the magnetic detection element.

本実施の形態においては、ホルダ６０２に保持される磁石６０１と、この磁石６０１と組み合わされるＧＭＲ素子６０５とで磁気センサを構成している。この磁気センサにおいては、磁石６０１による外部磁界をＧＭＲ素子６０５に作用させる。そして、ＧＭＲ素子６０５の電気抵抗値の変化を、磁石６０１による外部磁界の向きにより生じさせ、当該ＧＭＲ素子６０５の出力信号からＧＭＲ素子６０５と磁石６０１との相対移動量を検出する。本実施の形態に係る多方向入力装置１に接続された制御装置は、当該磁気センサで検出される上記相対移動量に基づいて、第１駆動部材４の回動角度を検出することが可能となる。   In the present embodiment, a magnet 601 held by a holder 602 and a GMR element 605 combined with the magnet 601 constitute a magnetic sensor. In this magnetic sensor, an external magnetic field by the magnet 601 is applied to the GMR element 605. Then, the change in the electric resistance value of the GMR element 605 is caused by the direction of the external magnetic field by the magnet 601, and the relative movement amount between the GMR element 605 and the magnet 601 is detected from the output signal of the GMR element 605.

磁気に感応して出力信号を出力するＧＭＲ素子６０５は、基本的な構成として、交換バイアス層（反強磁石層）、固定層（ピン止め磁性層）、非磁性層及び自由層（フリー磁性層）をウエハー（図示せず）上に積層して形成され、巨大磁気抵抗効果を利用したＧＭＲ(Giant Magnet Resistance)素子の一種である磁気抵抗効果素子として構成されている。   A GMR element 605 that outputs an output signal in response to magnetism basically has an exchange bias layer (antiferromagnetic layer), a fixed layer (pinned magnetic layer), a nonmagnetic layer, and a free layer (free magnetic layer). ) On a wafer (not shown), and is configured as a magnetoresistive effect element which is a kind of GMR (Giant Magnet Resistance) element utilizing a giant magnetoresistive effect.

なお、ＧＭＲ素子６０５が巨大磁気抵抗効果（ＧＭＲ）を発揮するためには、例えば、交換バイアス層がα−Ｆｅ２Ｏ３層、固定層がＮｉＦｅ層、非磁性層がＣｕ層、自由層がＮｉＦｅ層から形成されることが好ましいが、これらのものに限定されるものではなく、磁気抵抗効果を発揮するものであれば、いずれのものであってもよい。また、ＧＭＲ素子６０５は、磁気抵抗効果を発揮するものであれば、上記の積層構造のものに限定されるものではない。 For the GMR element 605 to exhibit the giant magnetoresistive effect (GMR), for example, the exchange bias layer is an α-Fe 2 O 3 layer, the fixed layer is a NiFe layer, the nonmagnetic layer is a Cu layer, and the free layer is Although it is preferable to form from a NiFe layer, it is not limited to these, and any may be used as long as it exhibits a magnetoresistive effect. Further, the GMR element 605 is not limited to the stacked structure as long as it exhibits a magnetoresistive effect.

スイッチ素子７は、図１に示すように、方形状に設けられており、その上面にボタン部７０１が設けられると共に、その下面部から下方側に伸びる複数の端子７０２が設けられている。ボタン部７０１は、操作軸３に対する押下操作に応じて一定範囲で上下方向に移動可能である。また、端子７０２は、スイッチ収容部２１２の穴部２１２ｂを介して不図示の基板に挿入される。   As shown in FIG. 1, the switch element 7 is provided in a rectangular shape, and a button portion 701 is provided on the upper surface thereof, and a plurality of terminals 702 extending downward from the lower surface portion are provided. The button unit 701 is movable in a vertical direction within a certain range in accordance with a pressing operation on the operation shaft 3. Further, the terminal 702 is inserted into a substrate (not shown) through the hole 212b of the switch housing portion 212.

このような構成を有する多方向入力装置１を組み立てると、図３に示すように、操作軸３の軸部３０２の上端部、並びに、第１駆動部材４の上方側の一部をケース２の開口部２２０から露出した状態で、各構成部品がケース２内に収納される。また、上側ケース２２の直交する側面部２２３に、回動検出機構６ａ及び６ｂが取り付けられる。なお、これらの回動検出機構６ａ及び６ｂを取り付ける際には、上述したように、磁石６０１を保持したホルダ６０２をカバー６０３に収容した状態で、このカバー６０３が有する突出片６０３ｃ及び係止片６０３ｅが、側面部２２３に形成された孔及びスリット部に挿入される。そして、係止片６０３ｅのフック部６０３ｆがスリット部の周縁と係合することで、回動検出機構６ａ及び６ｂが側面部２２３に固定される。   When the multidirectional input device 1 having such a configuration is assembled, as shown in FIG. 3, the upper end portion of the shaft portion 302 of the operation shaft 3 and a part on the upper side of the first drive member 4 are placed on the case 2. Each component is housed in the case 2 while being exposed from the opening 220. Further, the rotation detection mechanisms 6 a and 6 b are attached to the side surface portion 223 that is orthogonal to the upper case 22. When attaching these rotation detection mechanisms 6a and 6b, as described above, the protruding piece 603c and the locking piece of the cover 603 are accommodated in the state where the holder 602 holding the magnet 601 is accommodated in the cover 603. 603e is inserted into a hole and a slit formed in the side surface portion 223. Then, when the hook portion 603f of the locking piece 603e is engaged with the peripheral edge of the slit portion, the rotation detection mechanisms 6a and 6b are fixed to the side surface portion 223.

図４は、図３に示す本多方向入力装置１から上側ケース２２を取り外した場合の斜視図である。図４に示すように、上側ケース２２の内部においては、第１駆動部材４の下方に第２駆動部材５が直交して配設されている。第１駆動部材４の突起部４０２の下面が下側ケース２１の支持部２１３ｃにより支持される一方、第２駆動部材５のアーム部５０５の下面が下側ケース２１の支持部２１３ａにより支持されている。そして、これらの突起部４０２及びアーム部５０５に設けられた連結片４０３及び連結片５０６が、それぞれ回動検出機構６ａ及び６ｂが有するホルダ６０２の係合部６０２ａに係合する。   FIG. 4 is a perspective view when the upper case 22 is removed from the multidirectional input device 1 shown in FIG. As shown in FIG. 4, in the upper case 22, the second drive member 5 is disposed orthogonally below the first drive member 4. The lower surface of the protrusion 402 of the first drive member 4 is supported by the support portion 213c of the lower case 21, while the lower surface of the arm portion 505 of the second drive member 5 is supported by the support portion 213a of the lower case 21. Yes. Then, the connecting piece 403 and the connecting piece 506 provided on the protruding portion 402 and the arm portion 505 engage with the engaging portion 602a of the holder 602 included in the rotation detection mechanisms 6a and 6b, respectively.

このような構成を有する本多方向入力装置１において、操作軸３に対するＡ−Ｂ方向の傾動操作は、第２駆動部材５における図４に示すＸ−Ｙ方向の回転運動に変換される。一方、操作軸３に対するＣ−Ｄ方向の傾動操作は、第１駆動部材４における同図に示すＭ−Ｎ方向の回転運動に変換される。そして、回動検出機構６ａ及び６ｂにより、このような回転運動に応じた磁石６０１の回転に基づいて第１駆動部材４及び第２駆動部材５の回動量が検出され、不図示の制御装置にこれに応じた信号出力が行われることとなる。   In the multidirectional input device 1 having such a configuration, the tilting operation in the AB direction with respect to the operating shaft 3 is converted into the rotational movement in the XY direction shown in FIG. On the other hand, the tilting operation in the CD direction with respect to the operating shaft 3 is converted into the rotational motion in the MN direction shown in FIG. Then, the rotation detection mechanisms 6a and 6b detect the rotation amounts of the first drive member 4 and the second drive member 5 based on the rotation of the magnet 601 according to such a rotational motion, and the control device (not shown) In response to this, signal output is performed.

また、操作軸３に対する押下操作が行われると、軸支部３０３を介して第２駆動部材５が押し下げられる。これに伴い、第２駆動部材５のアーム部５０５によってスイッチ素子７のボタン部７０１が押し下げられる。そして、このようなスイッチ素子７により、このような押下操作が検出され、不図示の制御装置にこれに応じた信号出力が行われることとなる。   When the operation shaft 3 is pushed down, the second drive member 5 is pushed down via the shaft support portion 303. Accordingly, the button portion 701 of the switch element 7 is pushed down by the arm portion 505 of the second drive member 5. Then, such a pressing operation is detected by such a switch element 7 and a signal output corresponding to this is output to a control device (not shown).

このように本実施の形態に係る多方向入力装置１によれば、第１駆動部材４及び第２駆動部材５に連結されると共に磁石６０１を保持するホルダ６０２を回転可能に収容すると共に、ＧＭＲ素子６０５を所定位置に位置決めした状態でカバー６０３がケース２の外側から取り付けられる。このため、カバー６０３をケース２に対して取り付けるだけで第１駆動部材４及び第２駆動部材５と回動検出機構６ａ及び６ｂとを連結すると共に、磁石６０１とＧＭＲ素子６０５とを所望の位置に配置することができる。この結果、磁気センサを構成する磁石６０１とＧＭＲ素子６０５との位置精度を確保しつつ、装置本体に磁気センサを組み込む際の作業性に優れた多方向入力装置１を提供することが可能となる。   As described above, according to the multidirectional input device 1 according to the present embodiment, the holder 602 that is coupled to the first drive member 4 and the second drive member 5 and holds the magnet 601 is rotatably accommodated, and the GMR is provided. The cover 603 is attached from the outside of the case 2 with the element 605 positioned at a predetermined position. For this reason, the first drive member 4 and the second drive member 5 are connected to the rotation detection mechanisms 6a and 6b only by attaching the cover 603 to the case 2, and the magnet 601 and the GMR element 605 are connected to a desired position. Can be arranged. As a result, it is possible to provide the multidirectional input device 1 that is excellent in workability when the magnetic sensor is incorporated into the apparatus main body while ensuring the positional accuracy between the magnet 601 and the GMR element 605 constituting the magnetic sensor. .

特に、本実施の形態に係る多方向入力装置１においては、カバー６０３に、ケース２に形成されたスリット部に挿入される一対の係止片６０３ｅを設けている。これにより、一対の係止片６０３ｅをケース２のスリット部に挿入するだけでカバー６０３がケース２に係止されることから、回動検出機構６ａ及び６ｂ自体がケース２に取り付けられるので、装置本体に磁気センサを組み込む際の作業を簡素化することが可能となる。   In particular, in the multidirectional input device 1 according to the present embodiment, the cover 603 is provided with a pair of locking pieces 603e that are inserted into slit portions formed in the case 2. Thus, since the cover 603 is locked to the case 2 simply by inserting the pair of locking pieces 603e into the slit portion of the case 2, the rotation detection mechanisms 6a and 6b themselves are attached to the case 2, so that the device It is possible to simplify the work when incorporating the magnetic sensor into the main body.

また、本実施の形態に係る多方向入力装置１においては、カバー６０３に、ＧＭＲ素子６０５が実装された基板６０４に形成される孔６０４ａに挿入される挿入片６０３ｄを設けている。これにより、挿入片６０３ｄを基板６０４の孔６０４ａに挿入するだけで、カバー６０３におけるＧＭＲ素子６０５の位置を決定することができる。一方、磁石６０１を保持したホルダ６０２を収容することで、カバー６０３におけるＧＭＲ素子６０５の位置が決定されるので、磁石６０１とＧＭＲ素子６０５とを所望の位置に配置することが可能となる。   In the multidirectional input device 1 according to the present embodiment, the cover 603 is provided with an insertion piece 603d to be inserted into a hole 604a formed in the substrate 604 on which the GMR element 605 is mounted. As a result, the position of the GMR element 605 in the cover 603 can be determined simply by inserting the insertion piece 603 d into the hole 604 a of the substrate 604. On the other hand, since the position of the GMR element 605 in the cover 603 is determined by accommodating the holder 602 that holds the magnet 601, the magnet 601 and the GMR element 605 can be arranged at desired positions.

さらに、本実施の形態に係る多方向入力装置１においては、磁気検出素子としてＧＭＲ素子６０５を採用している。このように磁気検出素子としてＧＭＲ素子６０５を採用することにより、例えば、磁気検出素子にホール素子を用いた場合よりも高い分解能で操作軸３に対する操作量を検出することが可能となる。   Furthermore, in the multidirectional input device 1 according to the present embodiment, the GMR element 605 is employed as the magnetic detection element. By adopting the GMR element 605 as the magnetic detection element in this way, it becomes possible to detect the operation amount with respect to the operation shaft 3 with higher resolution than when, for example, a Hall element is used as the magnetic detection element.

なお、本発明は上記実施の形態に限定されず、種々変更して実施することが可能である。上記実施の形態において、添付図面に図示されている大きさや形状などについては、これに限定されず、本発明の効果を発揮する範囲内で適宜変更することが可能である。その他、本発明の目的の範囲を逸脱しない限りにおいて適宜変更して実施することが可能である。   In addition, this invention is not limited to the said embodiment, It can change and implement variously. In the above-described embodiment, the size, shape, and the like illustrated in the accompanying drawings are not limited to this, and can be appropriately changed within a range in which the effect of the present invention is exhibited.

例えば、上記実施の形態においては、回動検出機構６ａ及び６ｂが、第１駆動部材４及び第２駆動部材５の回動を検出する機能を有する場合についてのみ示しているが、回動検出機構６ａ及び６ｂの構成についてはこれに限定されるものではなく、適宜変更が可能である。例えば、第１駆動部材４及び第２駆動部材５の回動を検出する機能に加え、操作軸３を初期位置に復帰させる機能を付加するようにしても良い。   For example, in the above embodiment, the rotation detection mechanisms 6a and 6b are shown only when the first drive member 4 and the second drive member 5 have a function of detecting the rotation. The configurations of 6a and 6b are not limited to this, and can be appropriately changed. For example, in addition to the function of detecting the rotation of the first drive member 4 and the second drive member 5, a function of returning the operation shaft 3 to the initial position may be added.

図５は、上記実施の形態に係る多方向入力装置１において、操作軸３を初期位置に復帰させる機能を付加した場合の回動検出機構６ａ（６ｂ）の拡大図である。操作軸３を初期位置に復帰させる機能を付加する場合、図５に示すように、例えば、ホルダ６０２よりもケース２側の位置に、弾性部材としての付勢部材６０７を配設し、ホルダ６０２が初期位置に戻るように付勢しておくことが考えられる。この場合には、ホルダ６０２に付与される付勢力に応じて、ホルダ６０２に連結される第１駆動部材４（第２駆動部材５）が初期位置に戻される。これにより、第１駆動部材４（第２駆動部材５）に連結される操作軸３が初期位置に復帰することとなる。   FIG. 5 is an enlarged view of the rotation detection mechanism 6a (6b) when the function of returning the operation shaft 3 to the initial position is added to the multidirectional input device 1 according to the above embodiment. When a function for returning the operation shaft 3 to the initial position is added, as shown in FIG. 5, for example, an urging member 607 as an elastic member is disposed at a position closer to the case 2 than the holder 602, and the holder 602. It may be energized to return to the initial position. In this case, the first drive member 4 (second drive member 5) connected to the holder 602 is returned to the initial position in accordance with the urging force applied to the holder 602. As a result, the operation shaft 3 connected to the first drive member 4 (second drive member 5) returns to the initial position.

付勢部材６０７は、例えば、リン青銅等の弾性材料で形成される。カバー６０３に対応する略矩形状に設けられる平板部６０７ａを有しており、この平板部６０７ａの中央部には、円形状の開口部６０７ｂが形成されている。そして、この開口部６０７ｂの周囲に、半円弧形状を有する一対の板ばね部６０７ｃ、６０７ｄが形成されている。板ばね部６０７ｃが図５に示す下方に開口する一方、板ばね部６０７ｄが同図に示す上方に開口しており、共にその両端部で平板部６０７ａと連結されている。   The biasing member 607 is made of an elastic material such as phosphor bronze. A flat plate portion 607a provided in a substantially rectangular shape corresponding to the cover 603 is provided, and a circular opening 607b is formed at the center of the flat plate portion 607a. A pair of leaf springs 607c and 607d having a semicircular arc shape is formed around the opening 607b. The leaf spring portion 607c opens downward as shown in FIG. 5, while the leaf spring portion 607d opens upward as shown in FIG. 5, and both end portions are connected to the flat plate portion 607a.

板ばね部６０７ｃの中央部には、ホルダ６０２側に凸形状とされた突起部６０７ｅが形成されている。一方、ホルダ６０２における図５に示す上端部には、突起部６０７ｅを収容する収容部６０２ｂが設けられている。収容部６０２ｂは、第１駆動部材４（第２駆動部材５）が回動していない状態において、突起部６０７ｅを収容する位置に設けられている。また、付勢部材６０７の角部近傍には、カバー６０３の突出片６０３ｃに対応する位置に複数の孔６０７ｆが形成されている。   A protrusion 607e that is convex toward the holder 602 is formed at the center of the leaf spring 607c. On the other hand, an accommodation portion 602b that accommodates the protruding portion 607e is provided at the upper end portion of the holder 602 shown in FIG. The accommodating portion 602b is provided at a position where the protruding portion 607e is accommodated when the first driving member 4 (second driving member 5) is not rotating. In addition, a plurality of holes 607 f are formed in the vicinity of the corners of the urging member 607 at positions corresponding to the protruding pieces 603 c of the cover 603.

このような付勢部材６０７を備える場合において、操作軸３の傾動動作に応じて第１駆動部材４（第２駆動部材５）の回動に応じてホルダ６０２が回転すると、突起部６０７ｅがホルダ６０２の回転に応じて移動する。このとき、ホルダ６０２には、ホルダ６０２を初期位置に戻そうとする、板ばね６０７ｃの付勢力が付与される。このため、操作軸３が傾動動作から解放されると、ホルダ６０２が初期位置に戻されるのに従って、第１駆動部材４（第２駆動部材５）が初期位置に戻される。これにより、第１駆動部材４（第２駆動部材５）に連結される操作軸３が初期位置に復帰することとなる。   In the case of including such an urging member 607, when the holder 602 rotates according to the rotation of the first drive member 4 (second drive member 5) according to the tilting operation of the operation shaft 3, the protrusion 607e becomes the holder. It moves according to the rotation of 602. At this time, the urging force of the leaf spring 607c is applied to the holder 602 so as to return the holder 602 to the initial position. For this reason, when the operating shaft 3 is released from the tilting operation, the first driving member 4 (second driving member 5) is returned to the initial position as the holder 602 is returned to the initial position. As a result, the operation shaft 3 connected to the first drive member 4 (second drive member 5) returns to the initial position.

このように操作軸３を初期位置に復帰させる機能を回動検出機構６ａ（６ｂ）付加した場合には、付勢部材６０７によりホルダ６０２を初期位置に復帰させることができることから、これに連結された第１駆動部材４（第２駆動部材５）を初期位置に復帰させることができ、これに伴って操作軸３を初期位置に復帰させることができる。このような付勢部材６０７をケース２と回動検出機構６ａ（６ｂ）との間に配置することで、ケース２内の構成を簡素化しつつ、操作軸３を初期位置に復帰させることが可能となる。   When the rotation detecting mechanism 6a (6b) is added to the function of returning the operation shaft 3 to the initial position as described above, the holder 602 can be returned to the initial position by the urging member 607, and thus the operation shaft 3 is connected to the initial position. The first driving member 4 (second driving member 5) can be returned to the initial position, and the operation shaft 3 can be returned to the initial position accordingly. By disposing such an urging member 607 between the case 2 and the rotation detection mechanism 6a (6b), it is possible to return the operation shaft 3 to the initial position while simplifying the configuration in the case 2. It becomes.
