【発明の属する技術分野】
本発明はゲーム機器等の電子機器に使用される多方向入力装置に関する。
【０００２】
【従来の技術】
従来の多方向入力装置の図面を説明すると、図６は従来の多方向入力装置の分解斜視図、図７は従来の多方向入力装置に係り、操作部材の構成を示す断面図、図８は従来の多方向入力装置に係り、操作部材が中央部に位置した状態における操作部材と固定接点パターンとの関係を示す要部平面図、図９は従来の多方向入力装置に係り、操作部材が中央部から移動した状態における操作部材と固定接点パターンとの関係を示す要部平面図、図１０は従来の多方向入力装置に係り、絶縁基板の裏面図である。
【０００３】
次に、従来の多方向入力装置の構成を図６〜図１０に基づいて説明すると、絶縁樹脂の成型品からなる箱形のハウジング５１は、底壁５１ａと、この底壁５１ａから上方に延びる側壁５１ｂとを有する。
このハウジング５１の底壁５１ａ上には、平面的な導電パターンからなる互いに分離した一対の幅広の固定接点パターン５２，５３が設けられると共に、この一対の固定接点パターン５２，５３は、側壁５１ｂ外に延びる引き出し部５２ａ、５３ａが設けられている。
【０００４】
板材からなるカバー５４は、中央部に四角状の孔５４ａを有し、このカバー５４は、ハウジング５１の上方の開放部を覆うように、ハウジング５１に取り付けられ、このカバー５４とハウジング５１とによって、一つの筺体が形成されている。
【０００５】
絶縁基板５５は、中央部に四角状の孔５５ａを有すると共に、この絶縁基板５５の下面には、図３０で示すように、Ｘ方向検出部材５６と、このＸ方向検出部材５６と直角方向に配置されたＹ方向検出部材５７とが設けられている。
そして、Ｘ方向、Ｙ方向検出部材５６，５７は、それぞれ２個のパルス用パターン５６ａ、５７ａと、１個のコモン用パターン５６ｂ、５７ｂとからなる検出素子５６ｃ、５７ｃで構成されている。
そして、この絶縁基板５５は、Ｘ方向、Ｙ方向検出部材５６，５７を下方にして、筺体内に固定されている。
【０００６】
絶縁材からなるＸ方向スライド部材５８は、中心部の長手方向に長孔５８ａを有し、このＸ方向スライド部材５８は、Ｘ方向にスライド移動可能に、ハウジング５１と絶縁基板５５間に取り付けられいる。
また、絶縁材からなるＹ方向スライド部材５９は、中心部の長手方向に長孔５９ａを有し、このＹ方向スライド部材５９は、Ｙ方向にスライド移動可能に、ハウジング５１と絶縁基板５５間に取り付けられている。
【０００７】
そして、Ｘ方向、Ｙ方向スライド部材５８，５９は、互いに直交した状態で交差状態で配置され、Ｘ方向、Ｙ方向スライド部材５８，５９のそれぞれの一端側には、バネ性ある金属板からなる摺動子６０，６１が取り付けられている。
この摺動子６０，６１は、それぞれＸ方向、Ｙ方向スライド部材５８，５９の移動と共に可動して、それぞれ検出素子５６ｃ、５７ｃ上を摺動する。
その結果、Ｘ方向、Ｙ方向検出部材５６，５７によって信号が検出され、Ｘ、Ｙ方向の座標が検出されるようになる。
【０００８】
操作部材６２は、絶縁樹脂の成型品からなる保持体６３と、この保持体６３に取り付けられた操作部６４とで構成されている。
また、保持体６３は、四角状の鍔状部６３ａと、この鍔状部６３ａから上方に延びる筒状部６３ｂと、鍔状部６３ａの四方に設けられた４個の弾性腕部６３ｃとで構成されおり、そして、筒状部６３ｂにおいて、操作部６４が軸線方向に移動可能に取り付けられている。
【０００９】
また、このような操作部材６２は、鍔状部６３ａが固定接点パターン５２，５３と、下方に位置するＸ方向スライド部材５８との間に位置すると共に、操作部６４がＸ方向、Ｙ方向スライド部材５８，５９の交差する長孔５８ａ、５９ａと、絶縁基板５５の孔５５ａ、及びカバー５４の孔５４ａを通って外方に突出している。
【００１０】
そして、この操作部材６２は、ハウジング５１に対して平面的にＸ、Ｙ方向にスライド移動可能となっており、操作部材６２が移動すると、Ｘ方向、Ｙ方向スライド部材５８，５９を引っかけて、Ｘ方向、Ｙ方向スライド部材５８，５９が操作部材６２の移動に追従して可動し、Ｘ方向、Ｙ方向検出部材５６，５７が操作されるようになる。
【００１１】
また、操作部材６２の移動範囲の末端近傍においては、弾性腕部６３ｃがハウジング５１の側壁５１ｂに当接して、ハウジング５１に対する操作部材６２の衝撃を軟らかくしている。
【００１２】
プッシュ型のスイッチ６５は、特に図７に示すように、一対の摺動接点６６、６７と、この一対の摺動接点６６，６７間をＯＮ、ＯＦＦするドーム状の可動接点６８とで構成されている。
この一対の摺動接点６６，６７は、それぞれ接触部６６ａ、６７ａと、この接触部６６ａ、６７ａを支持する板状の支持部６６ｂ、６７ｂと、この支持部６６ｂ、６７ｂに繋がれた接点部６６ｃ、６７ｃとを有する。
【００１３】
そして、一対の摺動接点６６，６７は、保持体６３に埋設して取り付けられ、接触部６６ａ、６７ａが下方に突出した状態で、板状の支持部６６ｂ、６７ｂが保持体６３の下面に露出すると共に、接点部６６ｃ、６７ｃが筒状部６３ｂの底面に露出した状態となっている。
【００１４】
また、可動接点６８は、操作部６４によって押圧可能に筒状部６３ｂ内に収納されて、周辺部が接点部６６ｃに常時接触すると共に、中央部が接点部６７ｃに接離可能に配置されており、操作部６４が押圧された際、可動接点６８が変形して、中央部が接点部６７ｃに接触して、一対の摺動接点６６，６７間をＯＮ状態とし、また、操作部６４の押圧を解除すると、可動接点５８は自己のバネ性により元の状態に戻って、一対の摺動接点６６，６７間がＯＦＦの状態となる。
【００１５】
このような構成を有するスイッチ６５は、操作部材６２が筺体に取り付けられた際、板状の支持部６６ｂ、６７ｂがそれぞれ固定接点パターン５２，５３と近接した状態で対向すると共に、接触部６６ａ、６７ａがそれぞれ固定接点パターン５２，５３に接触した状態となる。
【００１６】
そして、一方の接触部６６ａは、操作部材６２の移動範囲内において、一方の固定接点パターン５２との接触が離れることが無く、また、他方の接触部６７ａは、操作部材６２の移動範囲内において、他方の固定接点パターン５３との接触が離れることが無いようになっており、このため、操作部材６２の移動範囲内においては、スイッチ６５のＯＮ、ＯＦＦの信号が引き出し部５２ａ、５３ａから引き出せるようになっている。
【００１７】
板材からなる板状部材６９は、第１，第２板部７０，７１で構成され、第１板部７０は、カバー５４と絶縁基板５５の孔５４ａ、５５ａより大きな外形を有し、中央部に操作部６４と同等の大きさの孔７０ａが設けられ、また、第２板部７１は、カバー５４と絶縁基板５５の孔５４ａ、５５ａより大きな外形を有し、中央部のＹ方向に長孔７１ａが設けられている。
【００１８】
そして、第１板部７０は絶縁基板５５上に配置されると共に、第２板部７１は、第１板部７０とカバー５４との間に配置されて、第１，第２板部７０，７１によって、カバー５４の孔５４ａの目隠し用としての機能を果たしており、操作部６４が孔７０ａと長孔７１ａを通って外方に突出している。
また、操作部材６２をスライド移動した際、第１板部７０は、操作部材６２の移動に追従して可動するが、第２板部７１は、操作部材６２のＸ方向の移動時のみ可動し、Ｙ方向の移動時は可動しないようになっている。
【００１９】
次に、従来の多方向入力装置の動作を説明すると、操作部６４を摘んで操作部材６２をスライド移動すると、これに追従して、Ｘ方向、Ｙ方向スライド部材５８，５９、及び摺動子６０，６１が移動し、その結果、Ｘ方向、Ｙ方向検出部材５６，５７が操作されて、Ｘ、Ｙ方向の座標が検出されるようになる。
【００２０】
そして、このような操作部材６２の動作は、図８で示す移動範囲の中央の位置から図９で示す移動範囲の末端の位置の間で行われる。
その間において、一対の摺動接点６６，６７の接触部６６ａ、６７ａは、それぞれ固定接点パターン５２，５３との接触が維持された状態となる。
【００２１】
次に、操作部６４を押圧すると、可動接点６８が変形して、中央部が接点部６７ｃに接触して、一対の摺動接点６６，６７間がＯＮ状態となり、その結果、固定接点パターン５２，５３間が導通した状態となる。
また、操作部６４の押圧を解除すると、可動接点５８は自己のバネ性により元の状態に戻って、一対の摺動接点６６，６７間がＯＦＦの状態となり、その結果、固定接点パターン５２，５３間が非導通の状態となる。
このスイッチ６５によって、例えば、座標位置の決定等を行うものである。
【００２２】
【発明が解決しようとする課題】
従来の多方向入力装置において、スイッチ６５の取り出しには、ハウジング５１の底壁５１ａ上のほぼ全面に設けられた幅広の固定接点パターン５２，５３を必要とし、コスト高で、生産性が悪いという問題がある。
また、広幅の固定接点パターン５２，５３は、精度の高い平面度が必要で、生産性が悪く、固定接点パターン５２，５３への摺動接点６６，６７の接触の信頼性に欠けるという問題がある。
また、目隠し用の板状部材６９が存在しても、カバー５４の孔５４ａと板状部材６９の間から侵入した埃等は、絶縁基板５５上に落ち、この埃等が絶縁基板５５と板状部６９との間の平面部を経由して、絶縁基板５５の孔５５ａから固定接点パターン５２，５３上に侵入し、スイッチ６５の信号引出が不確実なるという問題がある。
【００２３】
そこで、本発明は、生産性が良く、安価で、スイッチの信号取り出しの確実な多方向入力装置を提供することを目的とする。
【００２４】

【００６５】
また、操作部材２３の移動範囲の末端近傍においては、ダンパー部材２７がハウジング１の側壁１ｂに当接して、ハウジング１に対する操作部材２３の衝撃を軟らかくすると共に、絶縁基板１９の移動によって、Ｘ、Ｙ方向の末端検出部材２１，２２が操作されて、操作部材２３の移動範囲の末端、或いは末端近傍での信号が検出される。

【００７４】
そして、操作部材２３が移動範囲の末端近傍になると、ダンパー部材２７が側壁１ｂに当接し、また、ダンパー部材２７の弾性に抗して更に移動を続けると、保持体２４が側壁１ｂにぶつかって、操作部材２３の移動が停止する。
【００７５】
その間において、Ｘ方向の移動に際しては、Ｘ方向の末端検出部材２１が操作れて、Ｘ方向の末端の検出が行われ、また、Ｙ方向の移動に際しては、Ｙ方向の末端検出部材２２が操作されて、Ｙ方向の末端の検出が行われるようになる。
更に、操作部材２３の移動範囲において、第１，第２摺動片３２，３３は、第１，第２導電部Ｄ１，Ｄ２との接触が維持された状態となる。
【００７６】
次に、操作部２６を押圧すると、可動接点３１が変形して、中央部が接点部２９ａに接触して、第１，第２接点部材２９，３０間がＯＮ状態となり、その結果、取り出し手段Ｔ１，Ｔ２と取り出し手段Ｔ３，Ｔ４との間が導通した状態となる。
また、操作部２６の押圧を解除すると、可動接点３１は自己のバネ性により元の状態に戻って、第１，第２接点部材２９，３０間がＯＦＦの状態となり、その結果、取り出し手段Ｔ１，Ｔ２と取り出し手段Ｔ３，Ｔ４との間が非導通の状態となる。
このスイッチ２８によって、例えば、座標位置の決定等を行うものである。
【００７７】
なお、この実施例は、Ｘ方向、Ｙ方向検出部材、末端検出部材、及び取り出し手段において、摺動子が固定側に設けられると共に、検出素子と摺動接点が可動側に設けられたもので説明したが、摺動子が可動側に設けられ、又、検出素子と摺動接点が固定側に設けられても良い。

FIG. 10 is a back view of an insulating substrate according to a conventional multidirectional input device, showing a relationship between the operation member and the fixed contact pattern in a state where the operation member is moved from the center.
[0003]
Next, the configuration of the conventional multi-directional input device will be described with reference to FIGS. 6 to 10. A box-shaped housing 51 made of a molded product of insulating resin extends upward from the bottom wall 51a. And a side wall 51b.
On the bottom wall 51a of the housing 51, there are provided a pair of wide fixed contact patterns 52, 53 made of a planar conductive pattern and separated from each other, and the pair of fixed contact patterns 52, 53 are provided outside the side wall 51b. Drawer portions 52a and 53a are provided.
[0004]
The cover 54 made of a plate material has a square hole 54 a at the center, and the cover 54 is attached to the housing 51 so as to cover the open portion above the housing 51. A single housing is formed.
[0005]
The insulating substrate 55 has a square hole 55a in the center, and an X-direction detection member 56 and a perpendicular direction to the X-direction detection member 56 are formed on the lower surface of the insulation substrate 55 as shown in FIG. An arranged Y-direction detection member 57 is provided.
The X-direction and Y-direction detection members 56 and 57 are configured by detection elements 56c and 57c each including two pulse patterns 56a and 57a and one common pattern 56b and 57b.
The insulating substrate 55 is fixed in the housing with the X direction and Y direction detection members 56 and 57 facing downward.
[0006]
The X-direction slide member 58 made of an insulating material has a long hole 58a in the longitudinal direction of the central portion, and the X-direction slide member 58 is attached between the housing 51 and the insulating substrate 55 so as to be slidable in the X direction. Yes.
The Y-direction slide member 59 made of an insulating material has a long hole 59a in the longitudinal direction of the central portion. The Y-direction slide member 59 is slidably movable in the Y direction between the housing 51 and the insulating substrate 55. It is attached.
[0007]
The X-direction and Y-direction slide members 58 and 59 are arranged in an intersecting state so as to be orthogonal to each other, and one end side of each of the X-direction and Y-direction slide members 58 and 59 is made of a springy metal plate. Sliders 60 and 61 are attached.
The sliders 60 and 61 move with the movement of the X-direction and Y-direction slide members 58 and 59, respectively, and slide on the detection elements 56c and 57c, respectively.
As a result, signals are detected by the X direction and Y direction detection members 56 and 57, and coordinates in the X and Y directions are detected.
[0008]
The operation member 62 includes a holding body 63 made of a molded product of insulating resin and an operation section 64 attached to the holding body 63.
In addition, the holding body 63 includes a square hook-shaped portion 63a, a cylindrical portion 63b extending upward from the hook-shaped portion 63a, and four elastic arm portions 63c provided on four sides of the hook-shaped portion 63a. In the cylindrical portion 63b, the operation portion 64 is attached so as to be movable in the axial direction.
[0009]
Further, in such an operation member 62, the hook-shaped portion 63a is positioned between the fixed contact patterns 52 and 53 and the X-direction slide member 58 positioned below, and the operation portion 64 is slid in the X-direction and Y-direction. The members 58, 59 project outward through the long holes 58a, 59a intersecting each other, the hole 55a of the insulating substrate 55, and the hole 54a of the cover 54.
[0010]
The operation member 62 is slidable in the X and Y directions in a plane with respect to the housing 51. When the operation member 62 moves, the X and Y direction slide members 58 and 59 are hooked. The X direction and Y direction slide members 58 and 59 move following the movement of the operation member 62, and the X direction and Y direction detection members 56 and 57 are operated.
[0011]
Further, in the vicinity of the end of the movement range of the operation member 62, the elastic arm portion 63 c comes into contact with the side wall 51 b of the housing 51 to soften the impact of the operation member 62 on the housing 51.
[0012]
As shown in FIG. 7 in particular, the push-type switch 65 includes a pair of sliding contacts 66 and 67, and a dome-shaped movable contact 68 that turns on and off between the pair of sliding contacts 66 and 67. ing.
The pair of sliding contacts 66 and 67 are contact portions 66a and 67a, plate-like support portions 66b and 67b that support the contact portions 66a and 67a, and contact portions connected to the support portions 66b and 67b, respectively. 66c, 67c.
[0013]
The pair of sliding contacts 66 and 67 are embedded and attached to the holding body 63, and the plate-like support parts 66 b and 67 b are formed on the lower surface of the holding body 63 with the contact parts 66 a and 67 a protruding downward. In addition to being exposed, the contact portions 66c and 67c are exposed on the bottom surface of the cylindrical portion 63b.
[0014]
The movable contact 68 is housed in the cylindrical portion 63b so that it can be pressed by the operation portion 64, the peripheral portion is always in contact with the contact portion 66c, and the central portion is disposed so as to be able to contact and separate from the contact portion 67c. When the operation portion 64 is pressed, the movable contact 68 is deformed, the central portion comes into contact with the contact portion 67c, and the pair of sliding contacts 66 and 67 are turned on. When the pressing is released, the movable contact 58 returns to its original state due to its own spring property, and the pair of sliding contacts 66 and 67 is turned off.
[0015]
In the switch 65 having such a configuration, when the operation member 62 is attached to the housing, the plate-like support portions 66b and 67b face each other in the state of being close to the fixed contact patterns 52 and 53, respectively, and the contact portions 66a, 67a comes into contact with the fixed contact patterns 52 and 53, respectively.
[0016]
One contact portion 66a does not leave contact with one fixed contact pattern 52 within the movement range of the operation member 62, and the other contact portion 67a does not move within the movement range of the operation member 62. Thus, the contact with the other fixed contact pattern 53 is not separated, and therefore, the ON / OFF signal of the switch 65 can be drawn out from the lead-out portions 52a and 53a within the movement range of the operation member 62. It is like that.
[0017]
A plate-like member 69 made of a plate material includes first and second plate portions 70 and 71, and the first plate portion 70 has an outer shape larger than the holes 54 a and 55 a of the cover 54 and the insulating substrate 55, and has a central portion. Is provided with a hole 70a having the same size as the operation portion 64, and the second plate portion 71 has a larger outer shape than the holes 54a and 55a of the cover 54 and the insulating substrate 55, and is long in the Y direction of the central portion. A hole 71a is provided.
[0018]
The first plate portion 70 is disposed on the insulating substrate 55, and the second plate portion 71 is disposed between the first plate portion 70 and the cover 54, and the first and second plate portions 70, 71 serves as a blindfold for the hole 54a of the cover 54, and the operation portion 64 protrudes outward through the hole 70a and the long hole 71a.
Further, when the operation member 62 is slid, the first plate portion 70 moves following the movement of the operation member 62, but the second plate portion 71 moves only when the operation member 62 moves in the X direction. When moving in the Y direction, it is not movable.
[0019]
Next, the operation of the conventional multi-directional input device will be described. When the operation member 62 is slid by moving the operation unit 64, the X- and Y-direction slide members 58 and 59 and the slider follow the operation member 62. As a result, the X and Y direction detecting members 56 and 57 are operated, and the coordinates in the X and Y directions are detected.
[0020]
Such operation of the operation member 62 is performed between the center position of the movement range shown in FIG. 8 and the end position of the movement range shown in FIG.
In the meantime, the contact portions 66a and 67a of the pair of sliding contacts 66 and 67 are kept in contact with the fixed contact patterns 52 and 53, respectively.
[0021]
Next, when the operation portion 64 is pressed, the movable contact 68 is deformed, the central portion comes into contact with the contact portion 67c, and the pair of sliding contacts 66, 67 are turned on. As a result, the fixed contact pattern 52 , 53 become conductive.
When the pressing of the operation unit 64 is released, the movable contact 58 returns to its original state due to its own spring property, and the pair of sliding contacts 66 and 67 are turned off. As a result, the fixed contact pattern 52, 53 is in a non-conductive state.
For example, the coordinate position is determined by the switch 65.
[0022]
[Problems to be solved by the invention]
In the conventional multidirectional input device, taking out the switch 65 requires wide fixed contact patterns 52 and 53 provided on almost the entire surface of the bottom wall 51a of the housing 51, which is expensive and poor in productivity. There's a problem.
In addition, the wide fixed contact patterns 52 and 53 require a high degree of flatness, the productivity is poor, and the contact of the sliding contacts 66 and 67 with the fixed contact patterns 52 and 53 is not reliable. is there.
Even if there is a blind plate-like member 69, dust or the like entering from between the hole 54 a of the cover 54 and the plate-like member 69 falls on the insulating substrate 55, and this dust or the like falls on the insulating substrate 55 and the plate. There is a problem that the signal extraction of the switch 65 becomes uncertain because it enters into the fixed contact patterns 52 and 53 from the hole 55a of the insulating substrate 55 via the flat portion between the shape portion 69.
