Description

【０００１】
【発明の属する技術分野】
本発明は、パチンコ機、アレンジボール機、雀球遊技機等の弾球遊技機に関するものである。
【０００２】
【従来の技術】
パチンコ機、アレンジボール機などの弾球遊技機では、ＣＰＵ、ＲＯＭ、ＲＡＭその他の電子部品が装着された制御基板により制御を行う電子制御方式を採用しており、例えば機能別に設けられた主制御基板、払い出し制御基板、発射制御基板等によって遊技動作、払い出し動作、発射動作等をそれぞれ制御するようになっている。
【０００３】
【発明が解決しようとする課題】
このような制御基板は、電磁波等のノイズに非常に敏感であり、このようなノイズが制御基板に飛来すると、制御素子が誤動作を起こして遊技動作や払い出し動作等が正常に行われなくなる場合がある。
【０００４】
ところで、遊技機の制御基板の動作に悪影響を与えるノイズの発生源としては、遊技機外部で発生する例えば携帯電話からの電磁波なども考えられるが、遊技機の内部の遊技球が最も主要な発生源であると考えられる。即ち、遊技機内では多数の遊技球が、互いに擦れ合ったり、或いは通路内の例えば樹脂製の壁面等に擦れながら流動を繰り返しており、遊技球は常に帯電しやすい状況にあり、このような状況で高い電荷を帯びた遊技球から発生したノイズが、制御基板に悪影響を与えるものと考えられる。
【０００５】
本発明は、このような問題点に鑑み、遊技球に生じた電荷を効率よく逃がし、制御基板へ悪影響を与えるノイズの発生を抑制できる弾球遊技機を提供することを目的とする。
【０００６】
【課題を解決するための手段】
本発明は、前枠２に設けられた遊技盤１２と、発射された遊技球を前記遊技盤１２側に向けて案内する発射レール１７と、該発射レール１７により前記遊技盤１２側に案内された遊技球を前記遊技盤１２の遊技領域２０の上部側に案内する外レール２１と、該外レール２１に案内されて前記遊技領域２０内に入った遊技球を前記遊技領域２０の下部側へと案内する内レール２２と、前記前枠２の前側に開閉自在に装着されたガラス扉４とを備えた弾球遊技機において、前記遊技盤１２の下部表面に面一状に装着された導通板３１，１３１により前記外レール２１と前記内レール２２とが導通され、前記遊技盤１２を下側から支持する支持板１４の前側に、発射レール装着板６７を介して前記発射レール１７が装着されると共にその発射レール装着板６７の上端部６７ａが前記支持板１４の上側に突出しており、前記遊技盤１２を前記前枠２に装着したとき、前記導通板３１，１３１の前側に前記発射レール装着板６７の上端部６７ａが当接して導通するようになっており、前記発射レール１７、前記外レール２１、前記内レール２２のうちの少なくとも１つを、導通手段９３，１０１，１１０を介して前記ガラス扉４に導通させたものである。
【０００７】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づいて詳述する。図１〜図８は本発明をパチンコ機として具現化した第１の実施形態を例示している。１は外枠、２は前枠で、外枠１の前側に上下一対のヒンジ３，３を介して開閉自在に枢着されている。４はガラス扉、５は前面開閉扉で、これらは前枠２の窓孔６に対応して上下に配置され、前枠２に開閉自在に枢支されている。７は発射用の遊技球を貯留する上皿で、前面開閉扉５の前側に装着され、上皿カバー８により覆われている。また、９は余剰球等を貯留する下皿、１０は灰皿で、これらは前面開閉扉５の下側で前枠２の前側に左右に配置され、下皿カバー１１により覆われている。１２は遊技盤で、前枠２の窓孔６に対応するように、前枠２の裏側の遊技盤装着枠１３に裏側から着脱自在に装着され、窓孔６の下部側で前枠２の裏側に装着された支持板１４により下側から支持されている。
【０００８】
１５は発射手段で、下皿９の一側で前枠２の前側に装着された発射ハンドル１６と、支持板１４の前側に装着された発射レール１７と、前枠２の裏側に配置された発射モータ１８及び打撃槌１９等を備え、発射ハンドル１６を操作したときに、発射モータ１８により打撃槌１９が作動して、前面開閉扉５の裏側に装着された図外の球送り手段により発射レール１７上に１個づつ供給される遊技球を遊技盤１２側に発射させるようになっている。
【０００９】
遊技盤１２には、図２に示すように、発射手段１５により発射された遊技球を遊技領域２０の上部側に案内する外レール２１と、この外レール２１に案内されて遊技領域２０内に入った遊技球を遊技領域２０の下部側へと案内する内レール２２とが環状に装着されると共に、遊技領域２０内には、液晶表示手段２３、特別図柄始動手段２４、大入賞手段２５、普通図柄始動手段２６、普通入賞手段２７等の各種遊技部品が配置されている。液晶表示手段２３は、特別図柄表示手段２８を構成するもので、その上部に普通図柄表示手段２９が設けられている。また、遊技盤１２の下部には、遊技領域２０の最下部に配置されるアウト口３０を備えたアウト口手段３１が設けられている。外レール２１及び内レール２２は金属製の薄板により形成されており、図外の固定釘により遊技盤１２の前面側に略垂直に立設されている。
【００１０】
アウト口手段３１は、金属製の薄板で形成され、図５及び図６に示すように、遊技領域２０の下部中央から遊技盤１２の下端部にわたって遊技盤１２の表面に例えば面一状に装着されている。このアウト口手段３１には、遊技領域２０の最下部中央位置に、開口状のアウト口３０が左右方向の長孔状に形成されており、その後側の遊技盤１２に前後方向に形成されたアウト球案内路３０ａに連通している。
【００１１】
アウト口手段３１の前側には、外レール２１及び内レール２２の一部分がそれぞれ配置されており、アウト口手段３１と外レール２１、アウト口手段３１と内レール２２とはそれぞれ互いに固着されて導通した状態となっている。内レール２２は、その最下部がアウト口３０の前側を通過するように配設され、その部分にはアウト口３０の下部形状に沿って後下がり状に形成された凹部２２ａが形成されており、遊技領域２０の最下部まで落下した遊技球をアウト口３０側に案内するようになっている。
【００１２】
遊技盤１２の裏側には、図３に示すように、その液晶表示手段２３等の遊技部品を裏側から覆う裏カバー３２が装着されている。裏カバー３２の裏側には、主制御基板３３を収納する主基板ケース３４と、ランプ表示制御基板３５を収納するランプ表示基板ケース３６と、音声制御基板３７を収納する音声基板ケース３８とが着脱自在に装着されている。
【００１３】
遊技盤装着枠１３は門形状であって、前枠２の窓孔６に沿って前枠２の裏側に固定され、この遊技盤装着枠１３の下端部間に、前面開閉扉５の裏側に対応するように支持板１４が前枠２の裏側に固定されている。遊技盤装着枠１３には、遊技盤１２を裏側から押圧して固定するように、裏機構板４１が上下一対のヒンジ４２，４２により開閉自在に枢着され、４個の締結具４３により遊技盤装着枠１３に締結されている。
【００１４】
裏機構板４１には、図３に示すように、その中央部に裏カバー３２が嵌合する開口部４４が形成され、この開口部４４の上側に遊技球タンク４５とタンクレール４６が、左右一側に払い出し手段４７が、下側に通路ユニット４８と設置部４９とが夫々設けられており、遊技球が大入賞手段２５等に入賞したとき、或いは図外の自動球貸し機から球貸し指令があったときに、遊技球タンク４５内の遊技球をタンクレール４６を経て払い出し手段４７により払い出し、その遊技球を通路ユニット４８を経て上皿７等に案内するようになっている。
【００１５】
設置部４９には、払い出し制御基板５０を収納する払い出し基板ケース５１と、電源基板５２を収納する電源基板ケース５３とが裏側から着脱自在に取り付けられている。なお、大入賞手段２５等に入賞して遊技盤１２の裏側に案内された遊技球は、裏カバー３２の下部で集められ、裏機構板４１側の回収通路を経て島側に排出されるようになっている。
【００１６】
支持板１４は合成樹脂製であって、図２に示すように、遊技盤１２を下側から支持する遊技盤支持部６１、この遊技盤支持部６１の前縁側から上方に突設して設けられた左右一対の起立板部６２、払い出し手段４７から払い出された遊技球を上皿７側に案内する案内通路６３、ファール球を下皿９側に案内するファール球回収通路６４、前面開閉扉５を開いたときに案内通路６３から零れた遊技球を下皿９側に案内する零れ球回収通路６５、裏側からスピーカが装着されるスピーカ装着部６６等が一体に形成されている。
【００１７】
また、支持板１４の前側には、発射レール装着板６７を介して発射レール１７が着脱自在に装着されている。発射レール１７は断面略Ｍ型に折り曲げて成形された板金製であって、平面状の金属板で形成された発射レール装着板６７の前側に、外レール２１側の後端部が高くなるように傾斜した状態で例えばネジ止め等により固定されており、発射レール１７と発射レール装着板６７とは互いに導通した状態となっている。
【００１８】
また、発射レール装着板６７は、その上端部６７ａを左右の起立板部６２，６２の間で遊技盤支持部６１の前縁側から上側に突出させた状態で、支持板１４の前側に例えばネジ止め等により着脱自在に固定されている。これにより、遊技盤１２を遊技盤装着枠１３に装着したとき、遊技盤１２のアウト口手段３１の前面側が発射レール装着板６７の上端部６７ａの裏面側に当接して導通状態となるようになっている。即ち、遊技盤１２を遊技盤装着枠１３に装着した状態では、発射レール１７、外レール２１、及び内レール２２が、アウト口手段３１及び発射レール装着板６７を介して互いに導通した状態となる。
【００１９】
ガラス扉４は、図４に示すように、扉枠７１と、この扉枠７１の前面側に装着された合成樹脂製の扉カバー７２と、扉枠７１の裏側に固定された左右一対のガラス保持レール７３，７４と、このガラス保持レール７３，７４の下端部間で扉枠７１の裏側に固定されたガラス受けレール７５と、左右のガラス保持レール７３，７４間に上側から挿入された２枚のガラス板７６とを備えている。
【００２０】
扉枠７１は、板金材を折り曲げて構成した板金製であって、図４に示すように、上枠部７７と下枠部７８と左右一対の側枠部７９，８０とを板金材により一体に備え、その各枠部内が遊技盤１２の遊技領域２０に対応する開口部８１となっている。そして、この扉枠７１には、その重量を極力軽減しつつ、重量を軽減しつつ簡単な構造で容易に製作でき、十分な強度、剛性を確保できるように、開口孔８２、連結部８３、折り曲げリブ８４等が設けられている。
【００２１】
ガラス保持レール７３，７４及びガラス受けレール７５は板金材を折り曲げることによって形成されており、図６に示すように、２枚のガラス板７６に対応する２個の嵌合溝８５，８６と取り付け部８７とを一体に備えている。ガラス保持レール７３，７４は、取り付け部８７が扉枠７１の各側枠部７９，８０の裏側に上下方向に固着され、ガラス受けレール７５は、取り付け部８７が下枠部７８の裏側に左右方向に固着されている。
【００２２】
更に、ガラス受けレール７５の裏側には、導通部材（導通手段）９３が設けられている。導通部材９３は、板金材を折り曲げることにより形成されており、ガラス受けレール７５の裏面に固着される支持部９７と、この支持部９７の一端側から後向きに略直角に突設された突設部９８とを備えており、更にこの突設部９８の先端側には、突設部９８の面外方向に突出するように緩やかに屈曲する屈曲部９９が形成されている。導通部材９３は、ガラス受けレール７５の裏側で且つ外レール２１と交差する部分に、突設部９８がその後方の外レール２１と略平行になるように突設部９８を左右に傾斜させた状態で配置されており、ガラス扉４を閉じたときに、屈曲部９９の凸面側が外レール２１の外面側に摺接するようになっている。
【００２３】
扉カバー７２は、扉枠７１を前側から覆うもので、合成樹脂材料により一体に成形されており、扉枠７１の裏面側から例えばネジ止め等により着脱自在に固定されている。扉カバー７２の内周には、扉枠７１の開口部８１に内側から嵌合する額縁部８８が一体に形成されている。額縁部８８は、扉枠７１が内側から見えないように覆っており、その後端はガラス板７６に近接する位置まで延設されている。
【００２４】
前面開閉扉５は、前枠２に開閉自在に枢着された板金製の開閉板９１を備えており、この開閉板９１の前側に、上皿７と上皿カバー８とが装着されている。また、開閉板９１の裏側には、打撃槌１９の動作と連動して上皿７内の遊技球を発射レール１７上に１個ずつ供給する図外の球送り手段と、発射レール１７の前側を覆うレールカバー部材９２とが装着されている。
【００２５】
開閉板９１の上縁部には、ガラス扉４の扉枠７１の下枠部７８の下縁側折り曲げリブ８４が前側から嵌合する嵌合受け部９１ａが一体に形成されており、ガラス扉４を開いた状態でなければ前面開閉扉５を開くことができないようになっている。レールカバー部材９２は、発射レール１７の前側に近接して配置される平板状のカバー板部９４と、このカバー板部９４の縁部の前側への延設部分であって、カバー板部９４を開閉板９１の後方側所定距離で支持する支持板部９５とを備えており、開閉板９１との間に略閉空間を形成している。
【００２６】
上記構成のパチンコ機において、遊技者が図外の自動球貸し機を操作すると、島側から供給されて遊技球タンク４５内に貯留されている遊技球が、タンクレール４６を経て払い出し手段４７により払い出され、通路ユニット４８を経て上皿７に排出される。上皿７内の遊技球は、発射手段１５側に順次流下し、その下流側において横一列状に整列する。遊技者が発射ハンドル１６を操作すると、発射モータ１８により打撃槌１９が作動すると共に、これと連動して図外の球送り手段により上皿７内の遊技球が発射レール１７上に１個ずつ供給され、これによって遊技球が遊技盤１２側に順次発射される。
【００２７】
発射された遊技球は、発射レール１７、外レール２１を経て遊技領域２０の上部に導かれる。その際、遊技球は、発射レール１７と接触したときにアウト口手段３１、外レール２１、導通部材９３を経てガラス扉４の扉枠７１に導通し、また外レール２１と接触したときに導通部材９３を経てガラス扉４の扉枠７１に導通するため、例えば島設備内や遊技機内で他の遊技球や通路壁等と擦れ合うことによって遊技球に生じていた電荷は、ガラス扉４側に流れてここから大気に放電されることにより除去される。
【００２８】
遊技領域２０内に案内された遊技球は、遊技釘等に衝突しながら遊技盤１２に沿って落下する間に普通入賞手段２７等に入賞し、或いは入賞しない遊技球は内レール２２に案内されてアウト口３０に入り、共に遊技盤１２の裏側に案内されて裏カバー３２の下部で集められ、裏機構板４１側の回収通路を経て島側に回収される。
【００２９】
遊技球が遊技領域２０内で内レール２２に接触すると、その遊技球はアウト口手段３１、外レール２１、導通部材９３を経てガラス扉４の扉枠７１に導通するため、例えば遊技盤１２の表面や各遊技部品等と擦れ合うことによって遊技球に生じていた電荷は、ガラス扉４側に流れてここから大気に放電されることにより除去される。遊技球が入賞すると、払い出し制御基板５０の制御により払い出し手段４７が動作し、その入賞に応じた所定数の遊技球が上皿７に払い出される。
【００３０】
以上説明したように、本実施の形態によれば、ガラス扉４を閉じると、図８に示すように、導通部材９３の屈曲部９９の凸面側が外レール２１の外面側に摺接し、且つ突設部９８の弾性力によって押し付けられた状態となり、外レール２１は、導通部材９３、ガラス受けレール７５を介してガラス扉４の扉枠７１に導通する。また、外レール２１は、アウト口手段３１を介して内レール２２及び発射レール１７とそれぞれ予め導通した状態にある。即ち、ガラス扉４を閉じた状態では、外レール２１、内レール２２、及び発射レール１７が、導通部材９３を介してガラス扉４の扉枠７１に導通することになる。これにより、帯電した遊技球が発射レール１７、外レール２１、或いは内レール２２に接すると、その遊技球の電荷は導通部材９３を介して表面積の大きいガラス扉４の扉枠７１に流れ、この扉枠７１の板面から緩やかに大気中に放電されるため、帯電した遊技球から発せられるノイズが主制御基板３３等の制御基板に悪影響を及ぼす不具合を防止できる。
【００３１】
また、導通部材９３を介して直接ガラス扉４側と導通する外レール２１に対して、更に内レール２２及び発射レール１７を導通させているため、例えば島側設備内や遊技機内において発射前の遊技球に生じた電荷は発射レール１７や外レール２１上で、発射後の例えば遊技領域２０内で遊技球に生じた電荷は内レール２２上で、それぞれ除去することが可能であり、ノイズ発生による制御基板への悪影響をより確実に防止できる。
【００３２】
更に、導通部材９３を、外レール２１に対して、遊技球の転動部分を避けた外面側に当接させているため、導通部材９３が障害となって遊技球の経路に影響を与える不具合を防止できる。
【００３３】
なお、更にガラス扉４の扉枠７１にグランド線を接続してもよい。この場合、帯電した遊技球が発射レール１７、外レール２１、或いは内レール２２に接触すると、扉枠７１の板面から大気放電する場合と比べて極めて短時間で電位が低下することになる。
【００３４】
また、上記第１の実施形態では、導通部材９３を外レール２１に接続するように構成したが、導通部材９３を、例えば内レール２２、或いは発射レール１７に接続するようにしても、同様の効果を得ることができる。
【００３５】
図９は、本発明の第２の実施形態を例示し、導通部材（導通手段）１０１を外レール２１側に設けた例を示している。導通部材１０１は、板金材を折り曲げることにより形成されており、外レール２１の外面側に固着される支持部１０２と、その支持部１０２の端部から外レール２１の面外方向で且つ斜め前向きに突設された当接部１０３とを一体に備えている。なお、導通部材１０１は、外レール２１の外面側で且つガラス受けレール７５と交差する部分に配置されている。その他の構成は第１の実施形態と同様である。
【００３６】
ガラス扉４を閉じると、図９に示すように、導通部材１０１の当接部１０３がガラス受けレール７５の裏側に押し付けられ、外レール２１は、導通部材１０１、ガラス受けレール７５を介してガラス扉４の扉枠７１に導通する。このように、導通部材１０１を外レール２１側に設けても、第１の実施形態と同様の効果を得ることが可能である。
【００３７】
なお、上記第２の実施形態では、導通部材１０１を外レール２１に設けた例を示したが、導通部材１０１を、内レール２２、或いは発射レール１７に設けても同様の効果を得ることができる。
【００３８】
図１０及び図１１は、本発明の第３の実施形態を例示し、外レール２１と内レール２２とをそれぞれ導通部材（導通手段）９３，１１０により個別にガラス扉４の扉枠７１に導通させ、更に発射レール１７を、アウト口手段３１′を介して内レール２２に導通させた例を示している。
【００３９】
導通部材９３は、第１の実施形態と全く同様に構成されており、ガラス受けレール７５の裏側に後向きに設けられている。また、導通部材１１０も、導通部材９３と同様、ガラス受けレール７５の裏面に固着される支持部１１１と、この支持部１１１の一端側から後向きに略直角に突設された突設部１１２と、この突設部１１２の先端側に設けられ、突設部１１２の面外方向に突出するように緩やかに屈曲する屈曲部１１３とを備え、アウト口３０の前側のガラス受けレール７５の裏側に、屈曲部１１３の凸面側が上向きとなるように配置されており、ガラス扉４を閉じたときに、屈曲部１１３の凸面側が内レール２２の凹部２２ａの下面側に摺接するようになっている。
【００４０】
アウト口手段３１′は、第１の実施形態におけるアウト口手段３１と略同様に構成されており、唯一異なるのは、アウト口３０近傍から遊技盤１２の下端部への延設部分が発射レール１７側に偏位して設けられており、外レール２１とは導通していない点である。
【００４１】
ガラス扉４を閉じると、図１１に示すように、導通部材９３の屈曲部９９が外レール２１の外面側に、導通部材１１０の屈曲部１１３が内レール２２の凹部２２ａの下面側に、それぞれ押し付けられ、外レール２１は導通部材９３及びガラス受けレール７５を介して、内レール２２は導通部材１１０及びガラス受けレール７５を介して、それぞれガラス扉４の扉枠７１に導通する。また、発射レール１７は、アウト口手段３１′を介して予め内レール２２に導通した状態にある。このように、外レール２１と内レール２２とをそれぞれ導通部材９３，１１０により個別にガラス扉４の扉枠７１に導通させ、更に発射レール１７を、アウト口手段３１′を介して内レール２２に導通させても、ガラス扉４を閉じた状態で外レール２１、内レール２２、及び発射レール１７の全てをガラス扉４の扉枠７１に導通させることができ、第１，第２の実施形態と同様の効果を得ることが可能である。
【００４２】
なお、これと同様に、例えば外レール２１と発射レール１７とを個別の導通部材によりそれぞれガラス扉４の扉枠７１に導通させ、更に内レール２２を外レール２１若しくは発射レール１７に導通させてもよいし、発射レール１７と内レール２２とを個別の導通部材によりそれぞれガラス扉４の扉枠７１に導通させ、更に外レール２１を発射レール１７若しくは内レール２２に導通させてもよい。或いは、発射レール１７、外レール２１，内レール２２を個別の導通部材によりそれぞれガラス扉４の扉枠７１に導通させてもよい。
【００４３】
図１２及び図１３は、本発明の第４の実施形態を例示し、第１の実施形態と同様の構成をアレンジボール機で実現した例を示している。アレンジボール機における遊技領域２０内の下部には、入賞口手段１２１が配置されている。入賞口手段１２１は、遊技盤１２の開口部１２２に裏側から着脱自在に装着された入賞ケース１２３と、この入賞ケース１２３に横一列状等に形成され且つ前側から入賞した遊技球を遊技盤１２の裏側へと誘導する複数個、例えば１６個の入賞口１２４と、各入賞口１２４に入賞した遊技球を検出する複数個、例えば１６個の入賞検出スイッチ１２５とを備え、遊技盤１２に沿って落下する遊技球が何れかの入賞口１２４に入賞して、入賞検出スイッチ１２５がその遊技球を検出するようになっている。
【００４４】
また、入賞口手段１２１の前側には、入賞ケース１２３等を前側から覆う入賞口カバー１２６が設けられている。この入賞口カバー１２６は、その下部側が内レール２２の内面側に沿って設けられた略半月状に形成されており、その前側には、各入賞口１２４に対応して１６個の表示部１２７が横一列状に設けられている。各表示部１２７は、遊技球が何れかの入賞口１２４に入賞したとき、それに対応する発光ランプ１２８が点灯するなどしてその入賞を表示するようになっている。
【００４５】
遊技盤１２の下部表面には、内レール２２の下側から遊技盤１２の下端部にわたって金属製の導通板１３１が面一状に装着されている。導通板１３１の上縁部は内レール２２と導通しており、また導通板１３１の下部前側には外レール２１の上流側端部が配置され、導通板１３１と外レール２１とも互いに導通している。また、遊技盤１２を遊技盤装着枠１３に装着したとき、導通板１３１の前側に発射レール装着板６７の上端部６７ａが当接し、導通板１３１と発射レール１７とが導通するようになっている。即ち、遊技盤１２を遊技盤装着枠１３に装着した状態では、発射レール１７、外レール２１、及び内レール２２が導通板１３１を介して互いに導通した状態になるようになっている。
【００４６】
また、導通部材９３は、第１の実施形態と同様、ガラス受けレール７５の裏側に装着されており、ガラス扉４を閉じたとき、導通部材９３の屈曲部９９が外レール２１の外面側に摺接し、外レール２１が、導通部材９３及びガラス受けレール７５を介してガラス扉４の扉枠７１に導通するようになっている。このように、アレンジボール機においても、アウト口手段３２に代えて例えば導通板１３１を設け、発射レール１７、外レール２１、及び内レール２２を導通させることにより、第１の実施形態と同様の効果を得ることが可能である。また、上述したその他の実施形態やその変形例についても、同様の変更によりアレンジボール機に適用することが可能である。
【００４７】
以上、本発明の各実施形態について詳述したが、各実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲内で種々の変更が可能である。例えば、実施形態では、発射レール１７、外レール２１、及び内レール２２の全てを、何らかの形でガラス扉４の扉枠７１に導通させるように構成したが、例えばそれらのうちの１又は２つのみをガラス扉４の扉枠７１に導通させるようにしてもよい。例えば、第１の実施形態においては、アウト口手段３１によって発射レール１７、外レール２１、及び内レール２２を導通させたが、これらを導通させず、外レール２１のみを導通部材９３によってガラス扉４の扉枠７１に導通させるようにしてもよい。
【００４８】
また、遊技盤１２の表面側と装飾シートとの間や、遊技盤１２の裏面側等に例えばシート状の導電性部材を貼着し、この導電性部材を介して発射レール１７、外レール２１、内レール２２の何れか２つ以上を導通させたり、更にそれらと導通部材９３等とを導通させてもよい。この場合、装飾シートを導電性樹脂等で形成してもよい。
【００４９】
また、大入賞手段２５等の入賞手段を発射レール１７、外レール２１、内レール２２の少なくとも１つに導通させ、導通部材９３等を介してガラス扉４に導通させてもよい。
【００５０】
また、導通部材９３等の導通手段は、外レール２１の外面側、内レール２２の下面側（外面側）に当接或いは装着するものに限らず、例えば外レール２１、内レール２２の前縁側や発射レール１７の側面側、下面側に当接或いは装着するようにしてもよい。また、導通部材９３等の導通手段は、外レール２１等に直接当接或いは装着して導通させるものに限らず、外レール２１等に導通した他の部材、例えばアウト口手段３１に当接或いは装着するように構成し、間接的に導通させるようにしてもよい。
【００５１】
更に、実施形態では弾球遊技機としてパチンコ機とアレンジボール機を例に挙げて説明したが、雀球遊技機、その他の弾球遊技機であっても同様に実施可能であることは言うまでもない。

In the pachinko machine configured as described above, when a player operates an automatic ball lending machine (not shown), the game balls supplied from the island side and stored in the game ball tank 45 are discharged by the payout means 47 via the tank rail 46. It is paid out and discharged to the upper plate 7 through the passage unit 48. The game balls in the upper plate 7 sequentially flow down to the launching means 15 side and are aligned in a horizontal row on the downstream side. When the player operates the firing handle 16, the striking rod 19 is actuated by the firing motor 18, and in conjunction with this, one game ball in the upper plate 7 is placed on the firing rail 17 one by one by ball feeding means (not shown). As a result, game balls are sequentially fired to the game board 12 side.
[0027]
The launched game ball is guided to the upper part of the game area 20 through the launch rail 17 and the outer rail 21. At that time, the game ball is conducted to the door frame 71 of the glass door 4 through the outlet means 31, the outer rail 21, and the conducting member 93 when coming into contact with the launch rail 17, and conducted when coming into contact with the outer rail 21. Since it is electrically connected to the door frame 71 of the glass door 4 through the member 93, for example, the electric charge generated in the game ball by rubbing with other game balls or passage walls in the island facility or the game machine is transferred to the glass door 4 side. It is removed by flowing and discharging from here to the atmosphere.
[0028]
A game ball guided into the game area 20 wins the normal winning means 27 while falling along the game board 12 while colliding with a game nail or the like, or a game ball that does not win is guided to the inner rail 22. Are then guided to the back side of the game board 12 and collected at the bottom of the back cover 32, and are collected on the island side through a collection path on the back mechanism plate 41 side.

When the game ball contacts the inner rail 22 in the game area 20, the game ball is conducted to the door frame 71 of the glass door 4 through the outlet means 31, the outer rail 21, and the conduction member 93. The electric charge generated in the game ball by rubbing against the surface and each game component etc. flows to the glass door 4 side and is removed by being discharged to the atmosphere from here. When the game ball wins, the payout means 47 operates under the control of the payout control board 50, and a predetermined number of game balls according to the win are paid out to the upper plate 7.
[0030]
As described above, according to the present embodiment, when the glass door 4 is closed, the convex surface side of the bent portion 99 of the conducting member 93 is in sliding contact with the outer surface side of the outer rail 21 as shown in FIG. The outer rail 21 is brought into conduction with the door frame 71 of the glass door 4 through the conduction member 93 and the glass receiving rail 75. Further, the outer rail 21 is in a state of being electrically connected in advance to the inner rail 22 and the firing rail 17 via the outlet means 31. That is, in a state where the glass door 4 is closed, the outer rail 21, the inner rail 22, and the firing rail 17 are conducted to the door frame 71 of the glass door 4 through the conducting member 93. As a result, when the charged game ball contacts the launch rail 17, the outer rail 21, or the inner rail 22, the charge of the game ball flows to the door frame 71 of the glass door 4 having a large surface area through the conductive member 93. Since the plate surface of the door frame 71 is slowly discharged into the atmosphere, it is possible to prevent a problem that noise generated from the charged game ball adversely affects the control board such as the main control board 33.
[0031]
Further, since the inner rail 22 and the launch rail 17 are further conducted with respect to the outer rail 21 that is directly conducted to the glass door 4 side through the conducting member 93, for example, before the launch in the island side equipment or the gaming machine. The charge generated in the game ball can be removed on the launch rail 17 and the outer rail 21, and the charge generated in the game ball in the game area 20 after launch can be removed on the inner rail 22, respectively. It is possible to more reliably prevent adverse effects on the control board due to.
[0032]
Furthermore, since the conducting member 93 is in contact with the outer rail 21 on the outer surface side avoiding the rolling part of the game ball, the conducting member 93 becomes an obstacle and affects the path of the game ball. Can be prevented.
[0033]
Further, a ground wire may be connected to the door frame 71 of the glass door 4. In this case, when the charged game ball comes into contact with the launch rail 17, the outer rail 21, or the inner rail 22, the potential is lowered in a very short time compared to the case where atmospheric discharge occurs from the plate surface of the door frame 71.
[0034]

Alternatively, the firing rail 17 may be in contact with or attached to the side surface and the bottom surface. Further, the conduction means such as the conduction member 93 is not limited to the one that directly contacts or is attached to the outer rail 21 or the like, and is connected to another member that is conducted to the outer rail 21 or the like, for example, the out port means 31 or the like. It may be configured to be worn and indirectly connected.
[0051]
Furthermore, in the embodiment, a pachinko machine and an arrangement ball machine have been described as examples of the ball game machine, but it goes without saying that it can be similarly applied to a sparrow ball game machine and other ball game machines. .
