Description

本考案は、例えば車載電気機器等のコントローラとして利用される、操作レバーを傾倒すると傾倒方向に応じた電気信号を出力する多方向入力装置に係り、特に、操作レバーの操作での操作音を低減させた多方向入力装置に関する。   The present invention relates to a multi-directional input device that is used as a controller of, for example, an in-vehicle electric device and outputs an electrical signal corresponding to the tilt direction when the operation lever is tilted. In particular, the operation sound during operation of the operation lever is reduced. The present invention relates to a multidirectional input device.

この種の多方向入力装置の従来技術として、例えば特許文献１に記載されている多方向入力装置では、図９に示すように筐体１０９と蓋体１１０および成形金属板１１１よりなるハウジング１０２の内底面中央部に、操作レバー１０１の押下操作により動作するプッシュスイッチを配置するとともに、操作レバー１０１の傾倒操作に伴い傾倒する導電性の可動体１０３が一体形接点群１３５とプッシュスイッチの周囲に露出して配置した複数の下側固定接点１２２のいずれかとを選択的に導通させる傾倒検出スイッチが構成されている。   As a conventional technique of this type of multidirectional input device, for example, in the multidirectional input device described in Patent Document 1, as shown in FIG. 9, a housing 102 including a casing 109, a lid 110, and a molded metal plate 111 is used. A push switch that is operated by pressing the operation lever 101 is disposed at the center of the inner bottom surface, and the conductive movable body 103 that is tilted when the operation lever 101 is tilted is disposed around the integrated contact group 135 and the push switch. A tilt detection switch that selectively conducts any one of the plurality of lower fixed contacts 122 that are exposed and arranged is configured.

操作レバー１０１に挿入した半球状鍔部１０７を可動体１０３の円筒部内に配置し、この円筒部の外側に配置した復帰ばね１０４によって可動体１０３を付勢することにより、半球状鍔部１０７を開口部１１０ａの球状内壁面に圧接させている。
操作レバー１０１が傾倒操作されると、この操作レバー１０１と一体的に傾く半球状鍔部１０７が可動体１０３を傾動させ、導電性の可動体１０３の上面側が一体形接点群１３５と接触し、可動体１０３の下面側が下側固定接点１２２のいずれかと接触し、一体形接点群１３５と下側固定接点１２２のいずれかとが導通することにより傾倒操作による所定の電気信号が出力される。
また、操作レバー１０１が下方に押下操作されると、半球状鍔部１０７は下降せず操作レバー１０１だけが下降し、操作レバー１０１がドーム状の可動接点１２３を押下し、可動接点１２３の中央部が反転して中央固定接点１２０に接触するので可動接点１２３と共通固定接点１２１とが導通し、プッシュスイッチが動作する。 The hemispherical collar portion 107 inserted into the operation lever 101 is disposed in the cylindrical portion of the movable body 103, and the movable body 103 is biased by the return spring 104 disposed on the outside of the cylindrical portion. It is pressed against the spherical inner wall surface of the opening 110a.
When the operation lever 101 is tilted, the hemispherical flange 107 tilted integrally with the operation lever 101 tilts the movable body 103, and the upper surface side of the conductive movable body 103 comes into contact with the integral contact group 135, When the lower surface side of the movable body 103 comes into contact with any one of the lower fixed contacts 122 and any one of the integrated contact group 135 and the lower fixed contact 122 becomes conductive, a predetermined electric signal is output by the tilting operation.
When the operation lever 101 is pressed downward, the hemispherical collar portion 107 does not descend but only the operation lever 101 descends, the operation lever 101 depresses the dome-shaped movable contact 123, and the center of the movable contact 123 Since the part is reversed and comes into contact with the central fixed contact 120, the movable contact 123 and the common fixed contact 121 are brought into conduction, and the push switch operates.

このような構成により、特許文献１に記載されている多方向入力装置は、操作レバー１０１の傾倒操作に伴って電気信号を出力させ、また、操作レバー１０１の押下操作によってプッシュスイッチを動作させることができる操作性に優れた多方向入力装置となっている。
さらに、操作レバー１０１が大きく傾倒させられた場合でも、緩衝用ゴム板１３４を設けたことにより半球状鍔部１０７が損傷することを回避する構造となっており、ロバスト性にも優れた多方向入力装置となっている。 With such a configuration, the multidirectional input device described in Patent Document 1 outputs an electrical signal when the operation lever 101 is tilted, and operates the push switch when the operation lever 101 is pressed. This is a multidirectional input device with excellent operability.
Further, even when the operation lever 101 is greatly tilted, the structure is such that the hemispherical flange portion 107 is prevented from being damaged by providing the buffer rubber plate 134, and is multi-directional with excellent robustness. It is an input device.

しかしながら、特許文献１に記載されている多方向入力装置では操作レバー１０１がさらに大きく傾倒させられた場合に、操作レバー１０１が蓋体１１０の開口部１１０ａと当接して停止する構造となっている。このため、操作レバー１０１が強い力で大きく傾倒させられた場合に操作レバー１０１が開口部１１０ａに当接する当接音が発生するという問題点があった。   However, in the multidirectional input device described in Patent Document 1, when the operation lever 101 is further tilted, the operation lever 101 comes into contact with the opening 110a of the lid 110 and stops. . For this reason, when the operation lever 101 is greatly tilted by a strong force, there is a problem in that a contact sound is generated when the operation lever 101 contacts the opening 110a.

操作レバー１０１と開口部１１０ａの当接音はごく小さい音で、従来の車載電気機器等では、周囲の騒音にマスキングされ問題にならなかった。しかし、近年の自動車の静寂化に伴い、特に、電気自動車や低速走行時のハイブリット車ではエンジンからの騒音が無く、このようなとりわけ静寂性の高い車種では操作レバー１０１と開口部１１０ａの当接音をより小さくすることが求められた。   The contact sound between the operation lever 101 and the opening 110a is very small, and in conventional in-vehicle electric devices and the like, it is masked by ambient noise and does not cause a problem. However, with the recent quietness of automobiles, there is no noise from the engine especially in electric cars and hybrid cars at low speeds. In such a quiet car model, the operation lever 101 and the opening 110a are in contact with each other. It was required to make the sound smaller.

操作レバー１０１と蓋体１１０の当接音をより小さくするには蓋体１１０の開口部１１０ａに緩衝用のゴム部品を配する等の対策が考えられるが、部品の追加により組み立て費用，部品費用が上昇するとともに、操作レバーを傾倒操作させたときの停止位置があいまいになり、操作感を損ねるという問題があった。   In order to further reduce the contact sound between the operation lever 101 and the lid 110, a countermeasure such as arranging a rubber part for cushioning in the opening 110a of the lid 110 can be considered. When the operation lever is tilted, the stop position becomes ambiguous and the operational feeling is impaired.

また、突出部の弾性変形量は極わずかであるため、操作レバーを傾倒操作させたときの停止位置が曖昧になることはなく、良好な操作感が得られる。
これにより、操作レバーが強い力で大きく傾倒操作された場合でも当接音が低減され、かつ操作感の良い多方向入力装置を提供することが可能となる。 In the multidirectional input device according to the first aspect of the present invention, when the operation lever is tilted, the protruding portion provided at the inner edge of the opening of the upper surface portion of the housing becomes a contact portion that contacts the operation lever. Since the protrusion provided on the inner edge of the opening of the upper surface portion is more flexible than the upper surface portion of the housing, when the operation lever contacts the protrusion which is the contact portion, the protrusion is slightly elastically deformed and produces a buffering effect. The contact sound when the operation lever contacts the contact portion can be reduced.
Further, since the amount of elastic deformation of the protruding portion is very small, the stop position when the operation lever is tilted is not ambiguous, and a good operational feeling can be obtained.
Thereby, even when the operation lever is largely tilted with a strong force, it is possible to provide a multidirectional input device with reduced contact noise and good operational feeling.

本考案の請求項２による多方向入力装置では、操作レバーの傾倒動作を所定の方向に案内する案内機構を有するとともに、突出部が所定の案内方向に対応して設けられた撓み易い突出片よりなるので、操作レバーが操作しやすい案内方向に操作されたときに、より当接音を低減させることができる。   The multi-directional input device according to claim 2 of the present invention has a guide mechanism for guiding the tilting operation of the operation lever in a predetermined direction, and the protruding portion is provided with a flexible bending piece provided corresponding to the predetermined guiding direction. Therefore, the contact noise can be further reduced when the operation lever is operated in a guide direction that is easy to operate.

本考案の請求項３による多方向入力装置では、突出片には先端側に向かうにつれて操作レバーとの距離が拡がる曲面部が設けられているとともに、この曲面部が操作レバーが当接する当接部となっているので、操作レバーと当接部の当接領域が広くなり、操作レバーやハウジングを合成樹脂材で形成した場合でも、当接に伴う削れや磨耗を低減できる。このため、ハウジング内部に異物が入り込みにくくなり、信頼性の高い多方向入力装置とすることができる。   In the multidirectional input device according to claim 3 of the present invention, the projecting piece is provided with a curved surface portion that increases in distance from the operation lever toward the distal end side, and the curved portion contacts the operation lever. Therefore, the contact area between the operation lever and the contact portion is widened, and even when the operation lever and the housing are formed of a synthetic resin material, it is possible to reduce wear and wear associated with contact. For this reason, it is difficult for foreign matters to enter the housing, and a highly reliable multidirectional input device can be obtained.

本考案の請求項４による多方向入力装置では、傾倒検出機構は操作レバーの周囲に設けられた複数のプッシュスイッチにより構成されているので、簡単な構造で多方向の傾倒操作を検出することができる。   In the multidirectional input device according to claim 4 of the present invention, since the tilt detection mechanism is configured by a plurality of push switches provided around the operation lever, the multidirectional tilt operation can be detected with a simple structure. it can.

本考案の請求項５による多方向入力装置では、操作レバーの傾倒操作方向が等角度間隔の８方向となっているので、上下左右の４方向の他にその中間方向にも操作できるので、操作性の良い多方向入力装置を提供できる。また、操作レバーの傾倒方向を２つのプッシュスイッチの出力により検出するので、操作方向が８方向と多くても誤検出を防止できる。   In the multi-directional input device according to claim 5 of the present invention, since the tilting operation direction of the operation lever is eight directions at equal angular intervals, it can be operated in the middle direction in addition to the four directions of up, down, left and right. A multidirectional input device with good characteristics can be provided. Further, since the tilt direction of the operation lever is detected by the outputs of the two push switches, it is possible to prevent erroneous detection even if the operation direction is as many as eight directions.

本考案の請求項６による多方向入力装置では、操作レバーが挿通されるとともに摺動部材が操作レバーの傾倒操作に従って平面移動する摺動部材を設けた。この摺動部材の椀状凹部に設けられた等角度間隔で放射状に延びる複数の凹状溝部に、付勢された当接体を当接させることにより摺動部材が等角度間隔の放射状の方向に案内され、移動容易となるので、摺動部材の貫通孔に傾倒自在に挿通された操作レバーの傾倒方向を適切に案内することができる。また、付勢された当接体と椀状凹部により、操作レバーの復帰機構の機能を持たせることができるので、多方向入力装置の操作性をさらに良好なものとできる。   In the multidirectional input device according to claim 6 of the present invention, a sliding member is provided in which the operating lever is inserted and the sliding member moves in a plane according to the tilting operation of the operating lever. The sliding member is brought into a radial direction at equal angular intervals by bringing a biased contact body into contact with a plurality of concave grooves extending radially at equal angular intervals provided in the bowl-shaped concave portion of the sliding member. Since it is guided and becomes easy to move, it is possible to appropriately guide the tilting direction of the operating lever that is tiltably inserted into the through hole of the sliding member. In addition, since the function of the return mechanism of the operation lever can be provided by the biased contact body and the bowl-shaped recess, the operability of the multidirectional input device can be further improved.

本考案の請求項７による多方向入力装置では、当接体と弾性部材が保持部材に収納され、当接体が摺動部材に当接した状態で保持部材を上ケースに係止する構成としたので、多方向入力装置の組み立て作業性が向上する。   In the multidirectional input device according to claim 7 of the present invention, the contact body and the elastic member are housed in the holding member, and the holding member is locked to the upper case in a state where the contact body is in contact with the sliding member. Therefore, the assembly workability of the multidirectional input device is improved.

本考案の請求項８による多方向入力装置では、操作レバーを押下操作することで動作する中央プッシュスイッチを設けたので、多方向入力装置の操作性が向上する。また、中央プッシュスイッチを構成するドーム状の中央弾性体の弾性力によって、駆動体を介して操作レバーを保持部材に傾倒可能に保持する構造としたので、操作レバーを保持する弾性部材を別途必要とせず、構造を簡略とできる。   In the multidirectional input device according to the eighth aspect of the present invention, since the central push switch that operates by depressing the operation lever is provided, the operability of the multidirectional input device is improved. In addition, the elastic force of the dome-shaped central elastic body that constitutes the central push switch is structured to hold the operating lever to the holding member via the drive body so that it can be tilted. Instead, the structure can be simplified.

本考案の請求項９による多方向入力装置では、操作レバーの回転操作を検出可能な構成としたので、使用者は手を離すことなく、一連の動作で傾倒操作と回転操作ができるので、操作性が良い多方向入力装置が実現できる。さらに、回転操作しても回転しない押圧部材で操作レバーの周囲に設けられた複数のプッシュスイッチを押圧する構造としたので、プッシュスイッチにラバードームを用いても、回転操作によりラバードームが摺動磨耗することがなく、操作性が良く耐久性に優れた多方向入力装置が実現できる。   In the multi-directional input device according to claim 9 of the present invention, since the rotation operation of the operation lever can be detected, the user can perform the tilt operation and the rotation operation by a series of operations without releasing his hand. A multi-directional input device with good performance can be realized.

保持部材４の収納部４ａに当接体８と弾性部材９を収容し、保持部材４の上面に摺動部材６および補助摺動部材７を設置し、この状態で上ケース１に挿入する。これにより、保持部材４の側面の保持部材係止爪４ｄが上ケース１の側面の保持部材係止孔１ｆに係止され、上ケース１に保持部材４が保持され、上ケース１と保持部材４の間に補助摺動部材７および摺動部材６が順に配設され、弾性部材９により当接体８が付勢されながら摺動部材６に当接する上ケース中間組み立て品となる。   The contact body 8 and the elastic member 9 are accommodated in the accommodating portion 4a of the holding member 4, and the sliding member 6 and the auxiliary sliding member 7 are installed on the upper surface of the holding member 4, and are inserted into the upper case 1 in this state. Thereby, the holding member locking claw 4d on the side surface of the holding member 4 is locked in the holding member locking hole 1f on the side surface of the upper case 1, and the holding member 4 is held by the upper case 1, and the upper case 1 and the holding member 4, the auxiliary sliding member 7 and the sliding member 6 are disposed in order, and the upper case intermediate assembly product that contacts the sliding member 6 while the contact body 8 is urged by the elastic member 9 is obtained.

下ケース２には中央固定接点２１ａ，固定接点２１ｂを有し光学検出部材２２とコネクタ２３が組み付けられた基板２１の上面側にラバー板１３およびスペーサー１２を順に置載する。この状態で、上方よりガイド部材１１を、ガイド部材１１の円柱状の脚部を下ケース２の底板部の孔部に挿入して取り付け、脚部の先端を下ケース２の底面側で熱かしめ等の方法で変形させ、ガイド部材１１を下ケース２に固定する。これにより下ケース２に基板２１，ラバー板１３，スペーサー１２およびガイド部材１１が取り付けられ、下ケース中間組み立て品となる。   The lower case 2 has a central fixed contact 21a and a fixed contact 21b, and a rubber plate 13 and a spacer 12 are placed in order on the upper surface side of the substrate 21 on which the optical detection member 22 and the connector 23 are assembled. In this state, the guide member 11 is attached from above by inserting the columnar leg portion of the guide member 11 into the hole of the bottom plate portion of the lower case 2, and the tip of the leg portion is heat-caulked on the bottom surface side of the lower case 2. The guide member 11 is fixed to the lower case 2 by being deformed by such a method. Thereby, the board | substrate 21, the rubber plate 13, the spacer 12, and the guide member 11 are attached to the lower case 2, and it becomes a lower case intermediate assembly product.

下ケース中間組み立て品のガイド部材１１の窪み部１１ａに傾斜案内爪１０ｃが係合するように押圧部材１０を設置し、さらに、ローター１５を下ケース２の段部２ｂに設置する。次に、ローター係合爪５ｄと回転凹部１５ｃが係合するように、操作レバー３が挿入された駆動体５を設置し、のち、上ケース１の板バネ保持部１ｈに板バネ１４の取り付け部１４ａを係合させたうえで、下ケース中間組み立て品と上ケース中間組み立て品を組み合わせる。   The pressing member 10 is installed so that the inclined guide claw 10c is engaged with the recess 11a of the guide member 11 of the lower case intermediate assembly product, and the rotor 15 is further installed on the step 2b of the lower case 2. Next, the drive body 5 into which the operation lever 3 is inserted is installed so that the rotor engagement claw 5d and the rotary recess 15c are engaged, and then the leaf spring 14 is attached to the leaf spring holding portion 1h of the upper case 1. After engaging the part 14a, the lower case intermediate assembly and the upper case intermediate assembly are combined.

これにより、上ケース１のケース係止爪１ｅが下ケース２のケース係止孔２ａに係止され、組み立ては完了する。   Thereby, the case locking claw 1e of the upper case 1 is locked in the case locking hole 2a of the lower case 2, and the assembly is completed.

上記のように、本考案の実施の形態に係る多方向入力装置では、上ケース１の側面には保持部材係止孔１ｆが設けられ、保持部材４の側面には保持部材係止爪４ｄが設けられている。この保持部材４係止孔と保持部材係止爪４ｄが係合することにより、保持部材４に弾性部材９，当接体８，摺動部材６および補助摺動部材７が組み込まれ、弾性部材９が当接体８を摺動部材６に押しつける方向に付勢し、当接体８が摺動部材６に当接した状態で、保持部材４が上ケース１に取り付けられた中間組み立て品を構成することが可能となる。   As described above, in the multidirectional input device according to the embodiment of the present invention, the holding member locking hole 1 f is provided on the side surface of the upper case 1, and the holding member locking claw 4 d is provided on the side surface of the holding member 4. Is provided. When the holding member 4 locking hole and the holding member locking claw 4d are engaged, the elastic member 9, the contact body 8, the sliding member 6 and the auxiliary sliding member 7 are incorporated in the holding member 4, and the elastic member An intermediate assembly in which the holding member 4 is attached to the upper case 1 in a state where the contact member 8 presses the contact member 8 against the sliding member 6 and the contact member 8 contacts the sliding member 6. It can be configured.

これにより、保持部材４は当接体８と弾性部材９とを収納する収納部４ａを有しており、ハウジングは、開口１ａが形成された上ケース１と、上ケース１に一体化される下ケース２とを備え、当接体８と弾性部材９とが収納部４ａに収納され、弾性部材９によって付勢された当接体８が摺動部材６に当接した状態で、保持部材４が上ケース１に係止された中間組み立て品を構成することができるので、組み立て作業性を向上させることが可能となる。   Accordingly, the holding member 4 has a storage portion 4a for storing the contact body 8 and the elastic member 9, and the housing is integrated with the upper case 1 in which the opening 1a is formed and the upper case 1. A holding member in a state in which the lower body 2 is provided, the contact body 8 and the elastic member 9 are stored in the storage portion 4a, and the contact body 8 biased by the elastic member 9 is in contact with the sliding member 6. Since an intermediate assembly product in which 4 is locked to the upper case 1 can be formed, it is possible to improve the assembly workability.

また、本考案の実施の形態に係る多方向入力装置では、基板２１には８つの固定接点２１ｂの他に中央プッシュスイッチを構成する中央固定接点２１ａと回転操作を検出する光学検出部材２２が組み込まれており、下ケース中間組み立て品には、多方向入力装置の傾倒操作，押下操作および回転操作を検出する全ての検出素子が組み込まれている。   Further, in the multidirectional input device according to the embodiment of the present invention, the substrate 21 includes the central fixed contact 21a constituting the central push switch and the optical detection member 22 for detecting the rotation operation in addition to the eight fixed contacts 21b. In the lower case intermediate assembly, all detection elements for detecting the tilting operation, the pressing operation and the rotating operation of the multidirectional input device are incorporated.

これにより、全ての検出素子が基板２１に設けられているので、組み立て配線工数を少なくすることができ、全ての検出素子を組み込まれた中間組み立て品が構成できるので検出素子の動作検査が容易になり、安定した品質の多方向入力装置を安価に提供することができる。   Thereby, since all the detection elements are provided on the substrate 21, the assembly wiring man-hour can be reduced, and an intermediate assembly including all the detection elements can be configured, so that the operation inspection of the detection elements can be easily performed. Thus, a stable quality multi-directional input device can be provided at low cost.

次に本考案の実施の形態に係る多方向入力装置を傾倒操作，押下操作および回転操作したときの構成部品の動作と、それぞれの操作の検出機構を説明する。   Next, the operation of the component when the multidirectional input device according to the embodiment of the present invention is tilted, pressed and rotated, and the detection mechanism of each operation will be described.

傾倒操作の説明に先立ち、図３から図５を参考に、本考案の実施の形態に係る多方向入力装置の初期状態を説明する。   Prior to the description of the tilting operation, the initial state of the multidirectional input device according to the embodiment of the present invention will be described with reference to FIGS.

It is BB sectional drawing of 4 (a).
FIG. 5 is a cross-sectional view showing a state in which the multi-directional input device of the present invention is tilted, (a) is a cross-sectional view taken along the line AA in FIG. 1, and (b) is a method of applying force to the pressing member 10. It is principal part sectional drawing explaining these.

本考案の多方向入力装置は、図３に示すように、初期状態では操作レバー３はスペーサー１２を介して中央弾性体１３ａにより上方に付勢され、操作レバー３は、駆動体５の筒状部５ｂに抜け止めされた状態で軸線方向に移動可能に保持されているので、駆動体５の球面状凸部５ａは保持部材４の球面状凹部４ｃに傾倒可能に保持される。
また、摺動部材６の下面側の椀状凹部６ａには当接体８が係合しており、当接体８は弾性部材９で上方に付勢されているので、摺動部材６は当接体８の先端部と椀状凹部６ａの中央部が一致する位置に保持される。 In the multidirectional input device of the present invention, as shown in FIG. 3, in the initial state, the operation lever 3 is biased upward by the central elastic body 13 a via the spacer 12, and the operation lever 3 is a cylindrical shape of the drive body 5. The spherical convex portion 5a of the driving body 5 is held in a tiltable manner in the spherical concave portion 4c of the holding member 4 because the spherical convex portion 5a of the driving member 5 is held so as to be movable in the axial direction while being prevented from being detached by the portion 5b.
Further, the contact member 8 is engaged with the flange-shaped recess 6a on the lower surface side of the slide member 6, and the contact member 8 is biased upward by the elastic member 9, so that the slide member 6 is The front end portion of the contact body 8 and the central portion of the bowl-shaped recess 6a are held at a position where they coincide.

摺動部材６の下面側には、２つの椀状凹部６ａが略中央のレバー貫通孔６ｂをはさみ対称位置に設けられている（図４（ａ）参照）。また、椀状凹部６ａの中央の最も深い頂部には中央凹部６ｃを有し、中央凹部６ｃの周辺に８つの凹状溝部６ｄが中央凹部６ｃを中心に等角度間隔で放射状に設けられている（図４（ａ）（ｂ）参照）。   On the lower surface side of the sliding member 6, two hook-shaped concave portions 6a are provided at symmetrical positions with the substantially central lever through hole 6b interposed therebetween (see FIG. 4A). Further, the deepest apex at the center of the bowl-shaped recess 6a has a center recess 6c, and eight recess grooves 6d are provided radially at equal angular intervals around the center recess 6c around the center recess 6c ( (Refer FIG. 4 (a) (b)).

当接体８は先端部が椀状凹部６ａの中央部と当接体８の先端部が一致する方向に摺動部材６を移動させるが、椀状凹部６ａには中央凹部６ｃが設けられているので、初期状態では当接体８の先端部が中央凹部６ｃに係合して摺動部材６は停止する。
摺動部材６の２つの椀状凹部６ａは中央部の貫通孔をはさみ対称位置に設けられているので、当接体８の先端部が中央凹部６ｃに係合して摺動部材６が停止すると、摺動部材６のレバー貫通孔６ｂはセンターに位置する。 The abutting body 8 moves the sliding member 6 in a direction in which the tip of the abutting body 8 and the center of the abutting body 8 coincide with the tip of the abutting body 8. Therefore, in the initial state, the tip of the contact body 8 engages with the central recess 6c and the sliding member 6 stops.
Since the two bowl-shaped recesses 6a of the sliding member 6 are provided at symmetrical positions with the through hole in the center portion interposed therebetween, the tip of the contact body 8 engages with the center recess 6c and the sliding member 6 stops. Then, the lever through hole 6b of the sliding member 6 is located at the center.

摺動部材６は操作レバー３の傾倒操作に伴って摺動するが、操作されていないときには操作レバー３は摺動部材６により保持される。従って、初期状態では摺動部材６のレバー貫通孔６ｂがセンターに位置するため、操作レバー３もセンターに保持され、操作レバー３は上ケース１の開口１ａの中央に位置する。   Although the sliding member 6 slides with the tilting operation of the operation lever 3, the operation lever 3 is held by the sliding member 6 when it is not operated. Therefore, in the initial state, the lever through-hole 6b of the sliding member 6 is located at the center, so that the operation lever 3 is also held at the center, and the operation lever 3 is located at the center of the opening 1a of the upper case 1.

また、操作レバー３が傾倒操作されたのち開放されると、当接体８は当接体８の先端部が椀状凹部６ａの中央凹部６ｃと一致する方向に摺動部材６を移動させ、当接体８の先端部が中央凹部６ｃに係合すると摺動部材６は停止し、操作レバー３は初期状態の位置に復帰させられるので、復帰機構として機能する。   When the operation lever 3 is tilted and then released, the contact body 8 moves the sliding member 6 in a direction in which the tip of the contact body 8 coincides with the central recess 6c of the bowl-shaped recess 6a. When the tip of the contact body 8 is engaged with the central recess 6c, the sliding member 6 stops and the operation lever 3 is returned to the initial position, so that it functions as a return mechanism.

次に、図５（ａ）を参考に、操作レバー３を傾倒操作したときの構成部品の挙動を説明する。   Next, with reference to FIG. 5A, the behavior of the component parts when the operation lever 3 is tilted will be described.

操作レバー３が傾倒操作されると、操作レバー３を抜け止めした状態で保持する駆動体５も傾倒する。このとき、操作レバー３はスペーサー１２を介して中央弾性体１３ａにより上方に付勢されているので駆動体５も上方に付勢される。駆動体５の球面状凸部５ａは保持部材４の球面状凹部４ｃに係合しているので、駆動体５は操作レバー３とともに球面状凸部５ａを形成する仮想の球の中心を傾倒中心として傾倒可能となる。
摺動部材６のレバー貫通孔６ｂには操作レバー３が傾倒可能に保持されているので、操作レバー３が傾倒すると摺動部材６も操作レバー３の傾倒動作に伴って摺動する。 When the operating lever 3 is tilted, the driving body 5 that holds the operating lever 3 in a state where the operating lever 3 is prevented from coming off also tilts. At this time, since the operating lever 3 is biased upward by the central elastic body 13a via the spacer 12, the driving body 5 is also biased upward. Since the spherical convex portion 5 a of the driving body 5 is engaged with the spherical concave portion 4 c of the holding member 4, the driving body 5 is tilted about the center of a virtual sphere that forms the spherical convex portion 5 a together with the operation lever 3. Can be tilted as.
Since the operation lever 3 is tiltably held in the lever through hole 6 b of the sliding member 6, when the operation lever 3 is tilted, the sliding member 6 is also slid with the tilting operation of the operation lever 3.

補助摺動部材７は摺動案内部７ｃにより保持部材４に一軸方向に摺動可能に保持されており、摺動部材６は補助摺動部材７に補助摺動部材７の摺動方向とは直交する他軸方向に摺動可能に保持されているので、図５（ａ）に記載の如く、傾倒操作の方向が摺動部材６の摺動方向と同一の場合は、補助摺動部材７は摺動せず、摺動部材６だけが補助摺動部材７のガイド溝７ｂ中を摺動する。   The auxiliary sliding member 7 is held by the holding member 4 so as to be slidable in the uniaxial direction by the sliding guide portion 7c, and the sliding member 6 is the sliding direction of the auxiliary sliding member 7 with respect to the auxiliary sliding member 7. Since it is held so as to be slidable in the direction of the other orthogonal axis, when the direction of the tilting operation is the same as the sliding direction of the sliding member 6 as shown in FIG. Does not slide, and only the sliding member 6 slides in the guide groove 7 b of the auxiliary sliding member 7.

これに対し、傾倒方向が補助摺動部材７の摺動方向と同一、すなわち摺動部材６の摺動方向と直交する場合は、摺動部材６は補助摺動部材７に保持されたまま摺動せず、補助摺動部材７が摺動部材６を保持した状態で摺動する。   On the other hand, when the tilting direction is the same as the sliding direction of the auxiliary sliding member 7, that is, perpendicular to the sliding direction of the sliding member 6, the sliding member 6 is slid while being held by the auxiliary sliding member 7. The auxiliary sliding member 7 slides while holding the sliding member 6 without moving.

また、傾倒方向が摺動部材６の摺動方向と補助摺動部材７の摺動方向の中間の場合は、摺動部材６と補助摺動部材７が同時に摺動する。   When the tilting direction is intermediate between the sliding direction of the sliding member 6 and the sliding direction of the auxiliary sliding member 7, the sliding member 6 and the auxiliary sliding member 7 slide simultaneously.

いずれの傾倒方向の場合でも、摺動部材６および補助摺動部材７はそれぞれの摺動方向に摺動するが回転はしない。従って、摺動部材６は操作レバー３の傾倒操作に伴い操作レバー３の傾倒量に応じて平面移動し、摺動部材６に設けられた２つの椀状凹部６ａも移動する。   In any tilt direction, the sliding member 6 and the auxiliary sliding member 7 slide in the respective sliding directions but do not rotate. Accordingly, the sliding member 6 moves in a plane according to the tilting amount of the operation lever 3 in accordance with the tilting operation of the operating lever 3, and the two hook-shaped recesses 6 a provided on the sliding member 6 also move.

操作レバー３がわずかに傾倒操作され、摺動部材６がわずかに移動すると椀状凹部６ａもわずかに移動し、初期状態で椀状凹部６ａの中央凹部６ｃに係合していた当接体８は反付勢方向、すなわち摺動部材６から遠ざかる方向に移動させられる。しかし、当接体８は弾性部材９により付勢されているので、当接体８は摺動部材６を初期状態の位置に引き戻そうとし、操作レバー３も初期状態の位置に戻るように付勢される。これにより、使用者が操作レバー３を傾倒操作すると使用者は操作レバー３が初期状態の位置に引き戻される方向の手応えを感じることができ、操作性のよい傾倒操作が可能となる。   When the operating lever 3 is slightly tilted and the sliding member 6 moves slightly, the hook-shaped recess 6a also moves slightly, and the contact body 8 engaged with the central recess 6c of the hook-shaped recess 6a in the initial state. Is moved in the counter-biasing direction, that is, in the direction away from the sliding member 6. However, since the contact body 8 is urged by the elastic member 9, the contact body 8 tries to pull back the sliding member 6 to the initial position, and the operation lever 3 is also urged to return to the initial position. Is done. Thereby, when the user tilts the operation lever 3, the user can feel the response in the direction in which the operation lever 3 is pulled back to the initial position, and the tilt operation with good operability becomes possible.

操作レバー３をさらに傾倒操作すると、摺動部材６はさらに移動し当接体８は椀状凹部６ａの中央凹部６ｃから抜け出し、中央凹部６ｃの周辺に等角度間隔に設けられた凹状溝部６ｄに移動する。   When the operation lever 3 is further tilted, the sliding member 6 further moves, and the contact body 8 comes out of the central recess 6c of the bowl-shaped recess 6a, and enters the concave groove 6d provided at equiangular intervals around the central recess 6c. Moving.

椀状凹部６ａに設けられた８つの凹状溝部６ｄは、中央凹部６ｃを中心に等角度間隔で８方向に設けられており（図４（ａ）参照）、凹状溝部６ｄと中央凹部６ｃの交差部が最も深く、外縁に近づくに従い浅くなるような形状となっており（図４（ｂ）参照）、各々の凹状溝部６ｄの幅方向の中央が谷底部６ｅとなっている。   The eight concave groove portions 6d provided in the bowl-shaped concave portion 6a are provided in eight directions at equiangular intervals around the central concave portion 6c (see FIG. 4A), and the intersection of the concave groove portion 6d and the central concave portion 6c. The portion is deepest and becomes shallower as it approaches the outer edge (see FIG. 4B), and the center in the width direction of each concave groove portion 6d is a valley bottom portion 6e.

椀状凹部６ａの凹状溝部６ｄに移動した当接体８は、弾性部材９による付勢により凹状溝部６ｄの谷底部６ｅに押しつけられる。このため、操作レバー３がさらに傾倒操作され当接体８が凹状溝部６ｄに移動したときに、当接体８が凹状溝部６ｄの谷底部６ｅに当接していないと、弾性部材９の付勢力により当接体８は、当接体８の先端部と凹状溝部６ｄの谷底部６ｅが当接する方向に摺動部材６を移動させる。当接体８が凹状溝部６ｄの谷底部６ｅに係合すると当接体８は凹状溝部６ｄの谷底部に案内されて移動容易となり、凹状溝部６ｄが等角度間隔で８方向に設けられているので、操作レバー３は８方向に案内される。
これにより、使用者が本考案の多方向入力装置を傾倒操作する際に、操作レバー３をおおよその方向に傾倒操作しても、操作レバー３が所定の８方向のいずれかに案内されるので、操作性のよい多方向入力装置が実現できる。 The contact body 8 that has moved to the concave groove portion 6d of the bowl-shaped concave portion 6a is pressed against the valley bottom portion 6e of the concave groove portion 6d by urging by the elastic member 9. For this reason, when the operation lever 3 is further tilted and the contact body 8 moves to the concave groove portion 6d, if the contact body 8 does not contact the valley bottom portion 6e of the concave groove portion 6d, the biasing force of the elastic member 9 Thus, the abutting body 8 moves the sliding member 6 in a direction in which the tip of the abutting body 8 and the valley bottom 6e of the concave groove 6d abut. When the contact body 8 is engaged with the valley bottom portion 6e of the concave groove portion 6d, the contact body 8 is guided by the valley bottom portion of the concave groove portion 6d to facilitate movement, and the concave groove portions 6d are provided in eight directions at equal angular intervals. Therefore, the operation lever 3 is guided in eight directions.
Thus, when the user tilts the multi-directional input device of the present invention, even if the operating lever 3 is tilted in the approximate direction, the operating lever 3 is guided in one of the eight predetermined directions. A multidirectional input device with good operability can be realized.

以上のように、本考案の実施の形態に係る多方向入力装置では、操作レバー３を挿通させる駆動体貫通部（貫通部）４ｂを有するとともに、駆動体５を介して、操作レバー３を傾倒可能に保持する保持部材４を有し、操作レバー３を挿通させる長円貫通孔（貫通孔）７ａ（貫通孔）が設けられるとともに保持部材４により一軸方向に摺動可能に保持された補助摺動部材７と、操作レバー３を挿通させるレバー貫通孔（貫通孔）６ｂと等角度間隔で放射状に延びる８つの凹状溝部６ｄが形成された椀状凹部６ａとを有するとともに、補助摺動部材７により一軸方向と直交する他軸方向に摺動可能に保持されて操作レバー３の傾倒操作に伴って摺動する摺動部材６と、椀状凹部６ａに先端が当接される当接体８と、当接体８を摺動部材６側に常時付勢する弾性部材９とからなる案内機構を有している。
これにより、摺動部材６の椀状凹部６ａに設けられた等角度間隔で放射状に延びる８つの凹状溝部６ｄに、付勢された当接体８を当接させることにより摺動部材６が等角度間隔の放射状の方向に案内され移動容易となるので、摺動部材６のレバー貫通孔６ｂに傾倒自在に挿通された操作レバー３の傾倒方向を適切に案内することができる。また、付勢された当接体８と椀状凹部６ａにより、操作レバー３の復帰機構の機能を持たせることができるので、多方向入力装置の操作性をさらに良好なものとできる。 As described above, the multidirectional input device according to the embodiment of the present invention has the drive body penetration portion (penetration portion) 4b through which the operation lever 3 is inserted and tilts the operation lever 3 via the drive body 5. An auxiliary slide having an oval through hole (through hole) 7a (through hole) through which the operation lever 3 is inserted, and being held slidable in the uniaxial direction by the holding member 4. The auxiliary sliding member 7 includes a moving member 7, a lever through-hole (through-hole) 6 b through which the operation lever 3 is inserted, and a hook-shaped concave portion 6 a formed with eight concave groove portions 6 d extending radially at equal angular intervals. The sliding member 6 that is slidably held in the other axis direction orthogonal to the one axis direction and slides as the operation lever 3 is tilted, and the contact body 8 whose tip is in contact with the bowl-shaped recess 6a. The contact body 8 is always on the sliding member 6 side. And a guide mechanism consisting of an elastic member 9 for energizing.
As a result, the sliding member 6 is brought into contact with the eight abutting grooves 8d radially extending at equal angular intervals provided in the bowl-shaped recess 6a of the sliding member 6 by bringing the biased abutting body 8 into contact therewith. Since it is guided in the radial direction of the angular interval and becomes easy to move, it is possible to appropriately guide the tilting direction of the operation lever 3 that is tiltably inserted into the lever through hole 6b of the sliding member 6. Moreover, since the function of the return mechanism of the operation lever 3 can be provided by the biased contact body 8 and the bowl-shaped recess 6a, the operability of the multidirectional input device can be further improved.

次に、図５および図６を参照に、傾倒操作されたときの傾倒検出機構を説明する。   Next, with reference to FIGS. 5 and 6, the tilt detection mechanism when the tilt operation is performed will be described.

図６はプッシュスイッチの構成を説明する図で、（ａ）は傾倒操作方向とプッシュスイッチの配置を説明する平面図で、（ｂ）は、プッシュスイッチの構成を説明する図６のＣ−Ｃ断面図である。   6A and 6B are diagrams illustrating the configuration of the push switch. FIG. 6A is a plan view illustrating the tilting operation direction and the arrangement of the push switch, and FIG. 6B is a diagram illustrating the configuration of the push switch. It is sectional drawing.

傾倒操作は、図６（ａ）に示す、操作レバー３の周囲に等角度間隔で８つ設けられた、小弾性体１３ｂと固定接点２１ｂで構成されるプッシュスイッチ（周辺プッシュスイッチ）６０で検出される。   The tilting operation is detected by a push switch (peripheral push switch) 60 including eight small elastic bodies 13b and fixed contacts 21b provided at equal angular intervals around the operation lever 3 as shown in FIG. 6 (a). Is done.

本考案の多方向入力装置の傾倒操作では、図６（ａ）にＤ１からＤ８で示す、等間隔の８方向が傾倒検出方向となり、８つのプッシュスイッチ６０は、それぞれのプッシュスイッチ６０が８方向の傾倒検出方向の中間角度方向となるように配置されている。これにより、操作レバー３をいずれかの傾倒検出方向に傾倒操作すると、傾倒検出方向の両側に位置する２つのプッシュスイッチ６０がいずれも動作状態となる。これにより、任意の傾倒検出方向への傾倒操作により隣接する２つのプッシュスイッチ６０が動作するので、傾倒操作により１つのプッシュスイッチが動作する場合とくらべ、ゴミや削れ粉等による接点障害が起きにくく、耐久性に優れた多方向入力装置が実現できる。   In the tilting operation of the multi-directional input device of the present invention, eight equally spaced directions indicated by D1 to D8 in FIG. 6A are the tilt detection directions, and each of the eight push switches 60 has eight directions. It is arrange | positioned so that it may become the intermediate | middle angle direction of the inclination detection direction. Accordingly, when the operation lever 3 is tilted in any one of the tilt detection directions, both of the two push switches 60 located on both sides of the tilt detection direction are in an operating state. As a result, two adjacent push switches 60 are operated by a tilt operation in an arbitrary tilt detection direction, so that contact failure due to dust, shavings, etc. is less likely to occur than when one push switch is operated by a tilt operation. A multidirectional input device with excellent durability can be realized.

また、プッシュスイッチ６０は、図６（ｂ）に示すように、ラバー板１３の小弾性体１３ｂと基板２１の固定接点２１ｂで構成され、基板２１とラバー板１３はガイド部材１１により下ケース２に取り付けられる。   Further, as shown in FIG. 6B, the push switch 60 includes a small elastic body 13 b of the rubber plate 13 and a fixed contact 21 b of the substrate 21, and the substrate 21 and the rubber plate 13 are connected to the lower case 2 by the guide member 11. Attached to.

ガイド部材１１の上方には押圧部材１０が、押圧部材１０の傾斜案内爪１０ｃ（図２参照）がガイド部材１１の台形突出部１１ｂに設けられた４つの窪み部１１ａ（図２参照）と係合するように、置載される。押圧部材１０の下面に設けられた８つの押圧突出部１０ｂは、ガイド部材１１の孔部を貫通して突出する８つの小弾性体１３ｂの天面にそれぞれ当接し、また、押圧部材１０の上面には駆動体５の下面が当接する。これにより、押圧部材１０はガイド部材１１に回転移動が規制された状態で傾斜自在に保持される。   Above the guide member 11, the pressing member 10 is engaged with four depressions 11 a (see FIG. 2) in which the inclined guide claw 10 c (see FIG. 2) of the pressing member 10 is provided in the trapezoidal protrusion 11 b of the guide member 11. It is placed so as to match. The eight pressing protrusions 10 b provided on the lower surface of the pressing member 10 are in contact with the top surfaces of the eight small elastic bodies 13 b protruding through the holes of the guide member 11, and the upper surface of the pressing member 10. Is in contact with the lower surface of the driving body 5. Thereby, the pressing member 10 is tiltably held in a state in which the rotational movement is restricted by the guide member 11.

図６（ｂ）に示す、操作レバー３が傾倒操作されていない初期状態では、操作レバー３は上ケース１の開口１ａの中央部に位置しており、操作レバー３を保持する駆動体５の下面は水平となっている。従って、駆動体５の下面と当接する押圧部材１０も水平となっており、押圧部材１０の下面の８つの押圧突出部１０ｂとそれぞれ当接する８つの小弾性体１３ｂはいずれも押下されず、接点押圧部１３ｃと固定接点２１ｂは離間している。このため、固定接点２１ｂを構成する電気的に独立した２つの接点片は通電せず、８つのプッシュスイッチは全て動作していない。   In the initial state where the operation lever 3 is not tilted as shown in FIG. 6B, the operation lever 3 is located at the center of the opening 1a of the upper case 1 and the drive body 5 that holds the operation lever 3 is located. The lower surface is horizontal. Accordingly, the pressing member 10 in contact with the lower surface of the driving body 5 is also horizontal, and none of the eight small elastic bodies 13b in contact with the eight pressing protrusions 10b on the lower surface of the pressing member 10 is pressed down. The pressing portion 13c and the fixed contact 21b are separated from each other. For this reason, two electrically independent contact pieces constituting the fixed contact 21b are not energized, and all eight push switches are not operated.

操作レバー３が傾倒操作されると、図５（ａ）に示すように、操作レバー３を保持する駆動体５も傾倒動作する。駆動体５の本体部５ｃの下面は押圧部材１０の上面に設けられた輪環状突出部１０ａと当接しており、輪環状突出部１０ａの径は操作レバー３の径より大きいので、操作レバー３が傾倒操作されると輪環状突出部１０ａが大きく押下される。   When the operation lever 3 is tilted, the drive body 5 that holds the operation lever 3 also tilts as shown in FIG. The lower surface of the main body 5c of the driving body 5 is in contact with an annular projecting portion 10a provided on the upper surface of the pressing member 10, and the diameter of the annular projecting portion 10a is larger than the diameter of the operating lever 3. When the tilting operation is performed, the annular projecting portion 10a is largely pressed down.

輪環状突出部１０ａが押下されると、押圧突出部１０ｂが小弾性体１３ｂを押下し接点押圧部１３ｃが固定接点２１ｂと接触する。接点押圧部１３ｃは通電可能であるので、固定接点２１ｂを構成する２つの接点片が通電状態となりプッシュスイッチ６０が動作し、傾倒動作が検出される。   When the annular projecting portion 10a is pressed, the pressing projecting portion 10b presses the small elastic body 13b, and the contact pressing portion 13c comes into contact with the fixed contact 21b. Since the contact pressing portion 13c can be energized, the two contact pieces constituting the fixed contact 21b are energized, the push switch 60 is operated, and the tilting operation is detected.

操作レバー３が傾倒操作され傾倒操作側のプッシュスイッチ６０が押圧されているとき、図５（ｂ）に示すように、駆動体５の下面が押圧部材１０の輪環状突出部１０ａを下方に押し下げており（図中のｆ１）、押圧部材１０の押圧突出部１０ｂは小弾性体１３ｂにより上方に押し上げられている（図中のｆ２）。このとき、輪環状突出部１０ａは押圧突出部１０ｂより外側にあるので、押圧部材１０の反傾倒側は、ラバー板（弾性体）１３から離れる方向（図中のＲｆ方向）に付勢され、駆動体５の下面に近づく方向に付勢される。この付勢により押圧部材１０は傾倒した駆動体５の底面全体に当接する様に傾斜するので、小弾性体１３ｂを安定して押圧することができる。   When the operation lever 3 is tilted and the push switch 60 on the tilt operation side is pressed, the lower surface of the driving body 5 pushes down the annular projecting portion 10a of the pressing member 10 downward as shown in FIG. (F1 in the figure), and the pressing protrusion 10b of the pressing member 10 is pushed upward by the small elastic body 13b (f2 in the figure). At this time, since the annular projecting portion 10a is outside the pressing projecting portion 10b, the anti-tilting side of the pressing member 10 is urged in a direction away from the rubber plate (elastic body) 13 (Rf direction in the figure) It is urged in a direction approaching the lower surface of the driving body 5. By this urging, the pressing member 10 is tilted so as to contact the entire bottom surface of the tilted driving body 5, so that the small elastic body 13 b can be stably pressed.

また、操作レバー３を上方に付勢する中央弾性体１３ａの弾性力を小弾性体１３ｂより大きくしたので、操作レバー３の傾倒操作時に誤って操作レバー３を押下することが回避でき、安定した傾倒操作が可能となる。   In addition, since the elastic force of the central elastic body 13a that urges the operation lever 3 upward is larger than that of the small elastic body 13b, it is possible to prevent the operation lever 3 from being accidentally pressed during the tilting operation of the operation lever 3 and is stable. Tilt operation is possible.

なお、プッシュスイッチ６０の小弾性体１３ｂは押圧時にクリック感を生じない形状としたので、２つのプッシュスイッチ６０の動作タイミングに差が出ても２段クリックのような操作感を生じることが無く、感触の良い傾倒操作が可能となる。   Since the small elastic body 13b of the push switch 60 has a shape that does not cause a click feeling when pressed, there is no feeling of operation like a two-step click even if there is a difference in the operation timing of the two push switches 60. A tilting operation with a good feel is possible.

また、操作レバー３を回転操作しても回転しない押圧部材１０で操作レバー３の周囲に設けられた複数のプッシュスイッチ６０を押圧する構造としたので、プッシュスイッチ６０にラバードームを用いても、回転操作によりラバードームが摺動磨耗することがなく、操作性が良く耐久性に優れた多方向入力装置が実現できる。   Further, since the plurality of push switches 60 provided around the operation lever 3 are pressed by the pressing member 10 that does not rotate even when the operation lever 3 is rotated, even if a rubber dome is used for the push switch 60, The rubber dome does not slide and wear due to the rotation operation, and a multi-directional input device with excellent operability and durability can be realized.

また、上記のように、本考案の実施の形態に係る多方向入力装置では、傾倒検出機構は操作レバー３の周囲に等角度間隔で設けられた複数のプッシュスイッチ６０により構成されており、操作レバー３の傾倒操作に伴ってプッシュスイッチ６０を駆動する駆動体５が操作レバー３の外周側に設けられている。
これにより、簡単な構造で多方向の傾倒操作を検出することができる傾倒検出機構が構成できる。 Further, as described above, in the multidirectional input device according to the embodiment of the present invention, the tilt detection mechanism includes the plurality of push switches 60 provided at equal angular intervals around the operation lever 3, A drive body 5 that drives the push switch 60 in accordance with the tilting operation of the lever 3 is provided on the outer peripheral side of the operation lever 3.
Thus, a tilt detection mechanism that can detect a multi-directional tilt operation with a simple structure can be configured.

また、操作レバー３が傾倒操作する所定の方向は、等角度間隔の８方向であるとともに、プッシュスイッチ６０は、所定の方向の間に位置して８つ設けられており、操作レバー３を一方向に傾倒操作したとき、一方向を挟んで隣接する２つのプッシュスイッチ６０が駆動体５を介して駆動される。
これにより、操作レバー３の傾倒操作方向が等角度間隔の８方向となっているので、上下左右の４方向の他にその中間方向にも操作できるので、操作性の良い多方向入力装置を提供できる。また、操作レバー３の傾倒方向を２つのプッシュスイッチ６０の出力により検出するので、操作方向が８方向と多くても誤検出を防止できる。 The predetermined directions in which the operation lever 3 is tilted are eight directions at equal angular intervals, and eight push switches 60 are provided between the predetermined directions. When the tilting operation is performed in the direction, two push switches 60 adjacent to each other across one direction are driven via the driving body 5.
As a result, the tilting operation direction of the operation lever 3 is eight directions at equiangular intervals, so that it can be operated in the middle direction in addition to the four directions of up, down, left, and right, thus providing a multi-directional input device with good operability. it can. Further, since the tilt direction of the operation lever 3 is detected by the outputs of the two push switches 60, erroneous detection can be prevented even if the operation direction is as many as eight directions.

また、押圧部材１０は、下面に８つのプッシュスイッチ６０を押圧する８つの押圧突出部１０ｂを有し、上面に押圧突出部１０ｂの外側に位置する輪環状突出部１０ａを有するとともに、ガイド部材１１に傾斜自在に係合しており、駆動体５の下面と押圧突出部１０ｂより外側にある輪環状突出部１０ａとが当接するので、押圧突出部１０ｂへのプッシュスイッチ６０からの反力で押圧部材１０が駆動体５に押しつけられ、より安定したプッシュスイッチの押圧が可能となる。
さらに、操作レバー３を回転操作しても回転しない押圧部材１０の下面に複数の押圧突出部１０ｂを設ける構成としたので、操作レバー３が回転した状態で傾倒操作されても押圧突出部１０ｂがプッシュスイッチ６０を確実に押圧し、安定した傾倒操作が可能となる。 The pressing member 10 has eight pressing protrusions 10b that press the eight push switches 60 on the lower surface, an annular protrusion 10a that is positioned outside the pressing protrusion 10b on the upper surface, and a guide member 11. Since the lower surface of the driving body 5 and the annular annular protrusion 10a outside the pressing protrusion 10b are in contact with each other, the pressing force is applied by the reaction force from the push switch 60 to the pressing protrusion 10b. The member 10 is pressed against the driving body 5, and the push switch can be pressed more stably.
Further, since the plurality of pressing protrusions 10b are provided on the lower surface of the pressing member 10 that does not rotate even when the operation lever 3 is rotated, the pressing protrusion 10b is not tilted even when the operation lever 3 is rotated. The push switch 60 is surely pressed, and a stable tilting operation is possible.

次に、図７を参照に、操作レバー３が押下操作されたときの動作を説明する。図７は本考案の多方向入力装置を押下操作したときの状態を示す図１のＡ−Ａ位置の断面図である。   Next, an operation when the operation lever 3 is pressed down will be described with reference to FIG. FIG. 7 is a cross-sectional view taken along the line AA of FIG. 1 showing a state when the multidirectional input device of the present invention is pressed.

押下操作はラバー板１３の中央に設けられた中央弾性体１３ａと基板２１の中央に設けられた中央固定接点２１ａで構成される中央プッシュスイッチ６１により検出される。   The pressing operation is detected by a central push switch 61 including a central elastic body 13 a provided at the center of the rubber plate 13 and a central fixed contact 21 a provided at the center of the substrate 21.

ガイド部材１１のスペーサー収容部１１ｄに収容されるスペーサー１２は、中央弾性体１３ａによりスペーサー収容部１１ｄの天面に押圧されているが、操作レバー３の小径突出部３ｂがガイド部材１１のガイド孔１１ｃに挿入されると、小径突出部３ｂの下端面がスペーサー１２をわずかに押し下げ、操作レバー３はスペーサー１２を介して中央弾性体１３ａにより上方に付勢される。   The spacer 12 accommodated in the spacer accommodating portion 11d of the guide member 11 is pressed against the top surface of the spacer accommodating portion 11d by the central elastic body 13a, but the small-diameter protruding portion 3b of the operation lever 3 is the guide hole of the guide member 11. When inserted into 11c, the lower end surface of the small-diameter protruding portion 3b slightly pushes down the spacer 12, and the operation lever 3 is urged upward by the central elastic body 13a via the spacer 12.

操作レバー３は抜け止めされた状態で駆動体５の筒状部５ｂに操作レバー３の突出方向に沿った軸線方向に移動可能に保持されており、中央弾性体１３ａにより上方に付勢されている。   The operating lever 3 is held by the cylindrical portion 5b of the driving body 5 so as to be movable in the axial direction along the protruding direction of the operating lever 3, and is urged upward by the central elastic body 13a. Yes.

操作レバー３が押下操作されると、図７に示すように、操作レバー３は駆動体５の筒状部５ｂの中を下方に移動し、スペーサー１２を介して中央弾性体１３ａを押下する。中央弾性体１３ａはクリック感を発生しながら反転動作し、接点押圧部１３ｃが中央固定接点２１ａに当接する。接点押圧部１３ｃは通電可能であるので、中央固定接点２１ａを構成する２つの接点片が通電状態となり、これにより中央プッシュスイッチ６１が動作し押下操作が検出される。   When the operation lever 3 is pushed down, as shown in FIG. 7, the operation lever 3 moves downward in the cylindrical portion 5 b of the driving body 5 and pushes down the central elastic body 13 a via the spacer 12. The central elastic body 13a reverses while generating a click feeling, and the contact pressing portion 13c contacts the central fixed contact 21a. Since the contact pressing portion 13c can be energized, the two contact pieces constituting the center fixed contact 21a are energized, and the center push switch 61 is operated thereby to detect the pressing operation.

上記のように、本考案の実施の形態に係る多方向入力装置では操作レバー３を押下操作することで動作する中央プッシュスイッチ６１を設けたので、多方向入力装置の操作性が向上する。また、中央プッシュスイッチを構成するドーム状の中央弾性体１３ａの弾性力によって、駆動体５を介して操作レバー３を保持部材４に傾倒可能に保持する構造としたので、操作レバー３を保持する弾性部材を別途必要とせず、構造を簡略とできる。   As described above, in the multidirectional input device according to the embodiment of the present invention, the central push switch 61 that is operated by pressing the operation lever 3 is provided, so that the operability of the multidirectional input device is improved. Further, since the operation lever 3 is tiltably held by the holding member 4 via the driving body 5 by the elastic force of the dome-shaped central elastic body 13a constituting the central push switch, the operation lever 3 is held. An elastic member is not required separately, and the structure can be simplified.

次に、図３を参照に、操作レバー３が回転操作されたときの動作を説明する。   Next, the operation when the operation lever 3 is rotated will be described with reference to FIG.

操作レバー３はスペーサー１２を介して中央弾性体１３ａにより上方に付勢されており、駆動体５は操作レバー３を抜け止めした状態で保持しているので、駆動体５の球面状凸部５ａは保持部材４の球面状凹部４ｃに保持されている。これにより球面状凸部５ａは球面状凹部４ｃに沿って回転できるので、駆動体５は回転可能となる。操作レバー３は駆動体５と一体的に回転するように係合されているので、操作レバー３を回転操作すると駆動体５も回転する。   Since the operating lever 3 is biased upward by the central elastic body 13a via the spacer 12, and the driving body 5 holds the operating lever 3 in a state in which the operating lever 3 is prevented from coming off, the spherical convex portion 5a of the driving body 5 is retained. Is held in the spherical recess 4 c of the holding member 4. Thereby, since the spherical convex part 5a can rotate along the spherical concave part 4c, the drive body 5 becomes rotatable. Since the operation lever 3 is engaged with the drive body 5 so as to rotate integrally, the drive body 5 also rotates when the operation lever 3 is rotated.

操作レバー３の下端側の小径突出部３ｂはガイド部材１１のガイド孔１１ｃに上下移動自在、かつ、回転自在に保持されているので、操作レバー３は球面状凸部５ａと球面状凹部４ｃ、および小径突出部３ｂとガイド孔１１ｃの２カ所で回転自在に保持されるので、安定した回転動作が可能である。   Since the small-diameter protruding portion 3b on the lower end side of the operating lever 3 is held in the guide hole 11c of the guide member 11 so as to be vertically movable and rotatable, the operating lever 3 has a spherical convex portion 5a, a spherical concave portion 4c, In addition, since the small-diameter protruding portion 3b and the guide hole 11c are rotatably held at two locations, stable rotation operation is possible.

駆動体５の側面に設けられた４つのローター係合爪５ｄは、ローター１５の内径部に設けられた４つの回転凹部１５ｃと係合しているので、操作レバー３を回転操作するとローター１５も回転する。さらに、ローター１５と駆動体５は傾斜可能に係合しているので、操作レバー３が傾斜し駆動体５も傾斜している状態で操作レバー３を回転操作しても、ローター１５は支障なく回転する。   Since the four rotor engaging claws 5d provided on the side surface of the driving body 5 are engaged with the four rotating recesses 15c provided on the inner diameter portion of the rotor 15, the rotor 15 also moves when the operation lever 3 is rotated. Rotate. Furthermore, since the rotor 15 and the drive body 5 are tiltably engaged, even if the operation lever 3 is rotated while the operation lever 3 is tilted and the drive body 5 is also tilted, the rotor 15 is not hindered. Rotate.

ローター１５の上部には板バネ１４が設置され、板バネ１４の取り付け部１４ａ（図２参照）は上ケース１と下ケース２により固定され、クリック山部１４ｂが板バネ自体の弾性力により付勢されローター１５上面のカム山１５ｂに係合している。また、ローター１５の下面は下ケース２の内側部に設けられた段部２ｂに回転可能に保持される。   A leaf spring 14 is installed on the upper portion of the rotor 15, a mounting portion 14 a (see FIG. 2) of the leaf spring 14 is fixed by the upper case 1 and the lower case 2, and the click mountain portion 14 b is attached by the elastic force of the leaf spring itself. And is engaged with a cam crest 15 b on the upper surface of the rotor 15. Further, the lower surface of the rotor 15 is rotatably held by a step portion 2 b provided on the inner side of the lower case 2.

ローター１５の下面には、基板２１に設けられた光学検出部材２２の検出部を通過する複数の被検出壁部１５ａが設けられており、ローター１５が回転すると複数の被検出壁部１５ａが光学検出部材の検出部を順次通過し、回転動作が検出される。同時にローター１５の回転によりカム山１５ｂも移動し、クリック山部１４ｂが付勢されながらカム山１５ｂを乗り越えるので、操作レバー３を回転操作するとクリック感が得られ、操作性の良い回転操作が可能となる。   On the lower surface of the rotor 15, a plurality of detected wall portions 15 a that pass through a detection portion of the optical detection member 22 provided on the substrate 21 are provided, and when the rotor 15 rotates, the plurality of detected wall portions 15 a are optical. The detection unit of the detection member sequentially passes to detect the rotation operation. At the same time, the cam crest 15b is moved by the rotation of the rotor 15, and the cam crest 15b is moved while the click crest 14b is being urged. Therefore, when the operation lever 3 is rotated, a click feeling is obtained and rotation operation with good operability is possible. It becomes.

上記のように、本考案の実施の形態に係る多方向入力装置では操作レバー３が駆動体５を介して保持部材４の球面状凹部４ｃによって回転可能に保持されているとともに、駆動体５は操作レバー３と一体的に回転するように係合されている。さらに、多方向入力装置は駆動体５に係合されて一体的に回転可能なローター１５と、ローター１５の回転動作を検出するローター１５に対向して設けられた光学検出部材２２とを備え、操作レバー３の回転動作に伴って、ローター１５が一体的に回転する構造とした。
これにより、操作レバー３の回転操作とこの回転操作が検出可能な構成となり、使用者は手を離すことなく、一連の動作で傾倒操作と回転操作ができるので、操作性が良い多方向入力装置が実現できる。 As described above, in the multidirectional input device according to the embodiment of the present invention, the operation lever 3 is rotatably held by the spherical concave portion 4c of the holding member 4 via the drive body 5, and the drive body 5 is The control lever 3 is engaged so as to rotate integrally. Furthermore, the multidirectional input device includes a rotor 15 that is engaged with the drive body 5 and can rotate integrally, and an optical detection member 22 that is provided to face the rotor 15 that detects the rotational operation of the rotor 15. The rotor 15 is configured to rotate integrally with the rotation of the operation lever 3.
As a result, the rotation operation of the operation lever 3 and the rotation operation can be detected, and the user can perform the tilting operation and the rotation operation by a series of operations without releasing his hand. Can be realized.

また、中央弾性体１３ａの上面部と操作レバー３の先端部との間にスペーサー１２を配設し、スペーサー１２を保持する筒状のスペーサー収容部（収容部）１１ｄが設けられたガイド部材１１の天面に操作レバー３の小径突出部３ｂ（先端部）を上下移動自在、かつ、回転自在に保持するガイド孔１１ｃを設けた。
これにより、操作レバー３の安定した回転操作が可能となり、操作性が優れた多方向入力装置が実現できる。 The guide member 11 is provided with a spacer 12 between the upper surface portion of the central elastic body 13 a and the tip of the operation lever 3 and a cylindrical spacer accommodating portion (accommodating portion) 11 d for holding the spacer 12. A guide hole 11c for holding the small-diameter protruding portion 3b (tip portion) of the operation lever 3 up and down and rotating freely is provided on the top surface.
Thereby, the stable rotation operation of the operation lever 3 is attained, and a multidirectional input device with excellent operability can be realized.

次に、図５（ａ）および図８を参考に、操作レバー３が傾倒操作され操作レバー３がハウジングの開口１ａに当接したときに発生する当接音の低減構造を説明する。   Next, referring to FIG. 5A and FIG. 8, a structure for reducing a contact sound generated when the operation lever 3 is tilted and the operation lever 3 contacts the opening 1a of the housing will be described.

図８は上ケース１の当接部を説明する図であり、（ａ）は突出部の形状を説明する上ケース１の平面図で、（ｂ）は上ケース１に設けた突出部の断面形状を説明する図８（ａ）のＤ−Ｄ断面図で、（ｃ）は突出部の拡大断面図である。   8A and 8B are diagrams for explaining the contact portion of the upper case 1, wherein FIG. 8A is a plan view of the upper case 1 illustrating the shape of the protrusion, and FIG. 8B is a cross-section of the protrusion provided on the upper case 1. It is DD sectional drawing of Fig.8 (a) explaining a shape, (c) is an expanded sectional view of a protrusion part.

図５（ａ）に示すように、操作レバー３は駆動体５に保持されており、駆動体５の球面状凸部５ａは保持部材４の球面状凹部４ｃに係合しているので、操作レバー３は駆動体５の球面状凸部５ａの中心を傾倒中心として傾倒する。
操作レバー３は大きく傾倒操作されると、操作レバー３がハウジングの開口１ａに当接して停止する。このとき、操作レバー３を勢いよく操作すると操作レバー３が開口１ａに当接する当接音が発生する。 As shown in FIG. 5A, the operation lever 3 is held by the drive body 5, and the spherical convex portion 5a of the drive body 5 is engaged with the spherical concave portion 4c of the holding member 4. The lever 3 tilts with the center of the spherical convex portion 5a of the driving body 5 as the tilt center.
When the operation lever 3 is largely tilted, the operation lever 3 comes into contact with the opening 1a of the housing and stops. At this time, when the operation lever 3 is operated vigorously, a contact sound is generated in which the operation lever 3 contacts the opening 1a.

本考案の実施の形態に係る多方向入力装置では、図８（ａ）に示すように、ハウジングの開口１ａの内縁部に、操作レバー３の突出方向へ延出する突出片１ｂからなる突出部を設け、この突出部を操作レバー３が当接する当接部とした。
これにより、操作レバー３を大きく傾倒させると、図８（ｂ）および（ｃ）に想像線で示す様に、突出片１ｂの内周上端縁が操作レバー３と当接する当接部１ｇとなる。このとき、ハウジングの上面部の開口１ａの内縁部に設けた複数の突出片１ｂからなる突出部はハウジングの上面部より撓みやすいので、操作レバー３が突出片１ｂの当接部１ｇに当接すると突出片１ｂはわずかに弾性変形し緩衝効果を生じ、操作レバー３の当接音を低減させることができる。また、突出片１ｂの弾性変形量は極わずかであるため、操作レバー３を傾倒操作させたときの停止位置が曖昧になることはなく、良好な操作感が得られる。 In the multidirectional input device according to the embodiment of the present invention, as shown in FIG. 8 (a), a protruding portion comprising a protruding piece 1b extending in the protruding direction of the operating lever 3 at the inner edge of the opening 1a of the housing. The projecting portion is used as a contact portion with which the operation lever 3 contacts.
As a result, when the operation lever 3 is tilted greatly, the inner peripheral upper end edge of the projecting piece 1b becomes a contact portion 1g that contacts the operation lever 3 as shown by an imaginary line in FIGS. 8B and 8C. . At this time, since the projecting portion formed of the plurality of projecting pieces 1b provided at the inner edge of the opening 1a on the upper surface of the housing is more easily bent than the upper surface of the housing, the operation lever 3 contacts the abutting portion 1g of the projecting piece 1b. Then, the protruding piece 1b is slightly elastically deformed to produce a buffering effect, and the contact sound of the operation lever 3 can be reduced. Further, since the amount of elastic deformation of the protruding piece 1b is very small, the stop position when the operating lever 3 is tilted is not ambiguous, and a good operational feeling can be obtained.

これにより、操作レバー３が極めて大きく傾倒された場合でも操作レバー３は撓みやすい複数の突出片１ｂよりなる突出部に当接するので当接音が低減され、かつ傾倒操作させたときの停止位置が曖昧にならないので操作感の良い多方向入力装置を提供することが可能となる。   As a result, even when the operation lever 3 is tilted to a very large degree, the operation lever 3 abuts against a protruding portion made of a plurality of protruding pieces 1b that are easily bent, so that the contact sound is reduced and the stop position when the tilting operation is performed is reduced. Since it does not become ambiguous, it becomes possible to provide a multidirectional input device with a good operational feeling.

また、本考案の実施の形態に係る多方向入力装置では、８方向の傾倒方向が検出可能な構成となっており、検出可能な８方向の検出方向に案内する案内機構を設け、図８（ａ）に示すように、ハウジングの開口１ａの内縁部の突出部を、間隔を有して検出方向に対応して８個の突出片１ｂとした。
これにより、操作レバー３の傾倒操作を検出可能な８方向の検出方向に案内するので操作性が向上するとともに、突出部が検出可能な８方向の検出方向に対応して設けられた撓み易い突出片１ｂよりなるので、操作レバー３が操作しやすい検出方向に傾倒操作されたときに、より効果的に当接音を低減させることができる。 Further, the multi-directional input device according to the embodiment of the present invention has a configuration capable of detecting eight tilting directions, and is provided with a guide mechanism for guiding in eight detectable detection directions. As shown to a), the protrusion part of the inner edge part of the opening 1a of the housing was made into the eight protrusion pieces 1b corresponding to the detection direction at intervals.
As a result, the tilting operation of the operation lever 3 is guided in eight detection directions that can be detected, so that the operability is improved, and the protrusions that are provided corresponding to the eight detection directions in which the protrusions can be detected are easily bent. Since it consists of the piece 1b, when the operation lever 3 is tilted in an easy-to-operate detection direction, the contact noise can be reduced more effectively.

さらに、本考案の実施の形態に係る多方向入力装置では、図８（ｂ）および（ｃ）に示すように、突出片１ｂには先端側に向かうにつれて、初期状態における操作レバー３との距離が大きくなる曲面部ｒを設け、この曲面部ｒを当接部１ｇとした。
これにより、操作レバー３と当接部１ｇの当接領域が広くなり、操作レバー３やハウジングを合成樹脂材で形成した場合でも、当接に伴う削れや磨耗を低減できる。このため、ハウジング内部に異物が入り込みにくくなり、信頼性の高い多方向入力装置とすることができる。 Furthermore, in the multidirectional input device according to the embodiment of the present invention, as shown in FIGS. 8B and 8C, the distance between the protruding piece 1b and the operation lever 3 in the initial state as it goes toward the distal end side. A curved surface portion r is provided, and the curved surface portion r is defined as a contact portion 1g.
Thereby, the contact area of the operation lever 3 and the contact portion 1g is widened, and even when the operation lever 3 and the housing are formed of a synthetic resin material, it is possible to reduce wear and wear associated with contact. For this reason, it is difficult for foreign matters to enter the housing, and a highly reliable multidirectional input device can be obtained.

なお、以上の実施の形態に係る多方向入力装置では傾倒操作検出方向および案内方向は８方向としたが、検出方向および案内方向は８方向に限定されることはなく、８方向より少なくしても多くしても良い。   In the multi-directional input device according to the above-described embodiment, the tilt operation detection direction and the guide direction are eight directions. However, the detection direction and the guide direction are not limited to eight directions, and may be less than eight directions. You may also increase.

また、開口１ａの内縁部の突出部を、操作レバー３の突出方向へ延出する複数の突出片１ｂからなるものとしたが、突出部は１体のリング状の突出形状としても良い。   Moreover, although the protrusion part of the inner edge part of opening 1a shall consist of the some protrusion piece 1b extended in the protrusion direction of the operation lever 3, a protrusion part is good also as one ring-shaped protrusion shape.

また、突出片１ｂの当接部１ｇを曲面部としたが、当接部１ｇは初期状態における操作レバー３との距離が大きくなり、操作レバー３が当接するときに傾斜面部と操作レバー３の側面が平行になるような傾斜角の傾斜面としても良い。   In addition, although the contact portion 1g of the protruding piece 1b is a curved surface portion, the distance between the contact portion 1g and the operation lever 3 in the initial state increases, and when the operation lever 3 contacts, the inclined surface portion and the operation lever 3 It is good also as an inclined surface of the inclination angle which a side surface becomes parallel.

また、ローター１５の回転を検出する検出素子は光学検出部材２２としたが、磁気式検出素子や機械式検出部材を使用しても良い。   Further, although the detection element for detecting the rotation of the rotor 15 is the optical detection member 22, a magnetic detection element or a mechanical detection member may be used.

また、ラバー板１３の中央弾性体１３ａおよび小弾性体１３ｂの接点押圧部１３ｃに通電性がある材料を接合し接点押圧部１３ｃを通電可能とするものとしたが、ラバー板全体を導電性の材料で形成しても良い。   Moreover, although the material which has electroconductivity was joined to the center elastic body 13a of the rubber plate 13, and the contact pressing part 13c of the small elastic body 13b, and the contact pressing part 13c was made to be able to supply with electricity, the whole rubber plate was made into electroconductive. You may form with a material.

さらに、操作レバー３の傾倒動作を検出する傾倒検出機構は複数（本実施の形態では８つ）のプッシュスイッチ６０により構成するものとしたが、傾倒検出機構はこの構成には限定されない。例えば、操作レバー３の傾倒動作に伴って回動する、互いに直交する一対の駆動軸部材を設け、この駆動軸部材の回動を回転型可変抵抗器等で検出しても良い。   Furthermore, although the tilt detection mechanism for detecting the tilting operation of the operation lever 3 is configured by a plurality of (eight in the present embodiment) push switches 60, the tilt detection mechanism is not limited to this configuration. For example, a pair of drive shaft members that are orthogonal to each other and rotated in accordance with the tilting operation of the operation lever 3 may be provided, and the rotation of the drive shaft member may be detected by a rotary variable resistor or the like.
