Description

【０００１】
【発明の属する技術分野】
本発明は、パチンコ機に代表される弾球遊技機の技術分野に属し、詳しくは弾球遊技機に装備される入賞装置に関する。
【０００２】
【従来の技術】
パチンコ機等の弾球遊技機には入賞困難な状態と入賞容易な状態とに変化する可変入賞装置が装備されることが多い。そうした可変入賞装置の一種にアタッカーと呼ばれる形態のものがある。このアタッカーは、起立位置と倒伏位置とに往復変位可能な開閉板と、開閉板が起立位置にあるときに閉鎖され倒伏位置にあるときは開放され、開放時には倒伏している開閉板上を通過してきた遊技球を流入させる入賞開口とを備えており、いわゆる大当たり時に開放される大入賞口として使用されることが多い。
【０００３】
大入賞口として使用する場合、その内部に特別領域と非特別領域とを設定しておき、入賞した遊技球が特別領域を通過すれば大入賞口を継続開放させる遊技形態がある。この場合、継続開放するかしないかの不確実性が要求されることから、大入賞口の１回の開放期間における入賞球が特別領域を通過する確率をある程度に抑えている。現状では、この確率はほぼ１／３と規定されており、大入賞口の１回の開放期間での入賞球数は約１０球であるから、その中の３球程度が特別領域を通過する計算となる。
【０００４】
一方、遊技者にとっては、入賞球が特別領域を通過する確率が高ければ高いほど好ましいわけで、事実上１００％となることを望んでいる。そのため、かつては入賞球のほとんどを特別領域に誘導するような構造としたり、また見かけ上の確率を低くするために特別領域に１球流入するとその入口を閉鎖したり、特別領域の入口に１球目を滞留させて後続が特別領域に流入するのを阻んでいた。
【０００５】
【発明が解決しようとする課題】
しかし、入賞球のほとんどを特別領域に誘導するような構造では特別領域と非特別領域とを設定する意味が無くなり、特別領域への流入を阻止するのは入球不可能な入口を設けたのと同等になり弾球遊技の本質から外れるおそれがあった。
【０００６】
【課題を解決するための手段及び発明の効果】
請求項１記載の入賞装置は、背面を遊技盤の表面に接触させて遊技盤に固定される取付板と、前記取付板の軸受溝に挿入された一対の軸を中心にして起立位置と倒伏位置とに往復変位可能な開閉板と、該開閉板が前記起立位置にあるときに閉鎖され前記倒伏位置にあるときは開放され、該開放時には前記倒伏している開閉板上を通過してきた遊技球を流入させる入賞開口と、該入賞開口を通過した遊技球をいずれかに流入させるべく配された第１及び第２の内部領域とを備える入賞装置において、周囲を取り囲むフランジ部の表面よりも遊技者側に突出し前記入賞開口が開設された突出部が設けられた前記取付板と、前記軸の軸芯を前記フランジ部の表面よりも遊技者側にした前記開閉板と、前記入賞開口と第１及び第２の内部領域との間に介在し、前記入賞開口から第１及び第２の内部領域に至る経路を横切る方向に沿って第１位置と第２位置とに往復移動し、前記第１位置では前記入賞開口を通過した遊技球を前記第２の内部領域に流入し難くし、前記第２位置では前記入賞開口を通過した遊技球を前記第１の内部領域に流入し難くする移動体と、該移動体を往復駆動する駆動手段とを備えたので、移動体を第１位置と第２位置に変位させることにより、第２の内部領域に流入し難くしたり第１の内部領域に流入し難くしたりできる。逆に言えば、入賞球を第１の内部領域に誘導したり第２の内部領域に誘導したりできる。
【０００７】
例えば第１の内部領域を上述の特定領域、第２の内部領域を上述の非特定領域とした場合、特定領域に１球以上の入賞球が流入するまでは移動体を第１位置（非特定領域には流入しにくい状態）とし、特定領域に入賞球が流入した後に移動体を第２位置（特定領域には流入しにくい状態）とすればよい。こうすると、入賞開口の開放初期に入賞した遊技球は主に特定領域に向かうことになるので、いずれか１球が特定領域に流入する可能性は高い。よって、継続開放の可能性が高まるから遊技者の要望に応じることができる。その後に移動体を第２位置（特定領域には流入しにくい状態）にすればよい。
【０００８】
ただし、移動体を第１位置にした場合には非特定領域（第２の内部領域）に流入しにくくなり、第２位置にした場合には特定領域（第１の内部領域）に流入しにくくなるだけで、いずれの場合も非特定領域（第２の内部領域）または特定領域（第１の内部領域）を閉鎖する（遊技球が流入不可能にする）わけではないから、特別領域と非特別領域とを設定する意味が無くなることもないし、入球不可能な入口をつくって弾球遊技の本質を外すおそれもない。
【０００９】
なお、移動体を第１位置にしたときには、第１の内部領域に流入する球数：第２の内部領域に流入する球数＝ほぼ８：２、第２位置にしたときには、第１の内部領域に流入する球数：第２の内部領域に流入する球数＝ほぼ２：８となるように設定するとよい。こうすると、入賞開口を通過した入賞球の中の１球目か２球目あたりで特定領域に流入するものが出ると想定でき、残りの８〜９球の内の２球程度が特定領域に流入すると想定できる。つまり、１０球中３球程度が特定領域に流入することになり、ほぼ１／３という確率を実現できる。
【００１０】
請求項３記載のように、第１の内部領域と第２の内部領域とを遊技球の直径の２倍を超える軸間距離で入賞開口側から見て左右に並べて配置して、移動体は、内部領域同士の軸間距離と同間隔で配される一対の邪魔板を有しており、第１位置では入賞開口と第２の内部領域との間に邪魔板の一方を割り込ませて該第２の内部領域の前方のみを全面的に遮り、第２位置では入賞開口と第１の内部領域との間に邪魔板の他方を割り込ませて該第１の内部領域の前方のみを全面的に遮る構成は、上記した内部領域に流入する球数の比（８：２、２：８）の実現に適している。
【００１１】
一対の邪魔板の一方を入賞開口と第２の内部領域との間に割り込ませることで第２の内部領域へ流入しにくくし（このとき他方の邪魔板は入賞開口から第１の内部領域へ向かう球の移動を邪魔しない位置とし）、他方の邪魔板を入賞開口と第１の内部領域との間に割り込ませることで第１の内部領域へ流入しにくくする（このとき一方の邪魔板は入賞開口から第２の内部領域へ向かう球の移動を邪魔しない位置とする）ので、簡単な構成である。
【００１２】
また請求項１記載の入賞装置は、開閉板の軸芯をフランジ部の表面よりも遊技者側にしたので、軸芯からガラス板までの距離を小さくできる。これに応じて軸芯から開閉板の先端までの寸法を小さくできるから、開閉板の該寸法に対応する入賞開口の開口高さを小さくできる。この結果、入賞開口が設けられている部分の上下寸法も小さくできる。
【００１３】
軸受溝は請求項２のように突出部の背面側に設けるとよい。
また、請求項３記載のように、請求項１又は２の入賞装置において、前記第１の内部領域と前記第２の内部領域とを遊技球の直径の２倍を超える軸間距離で前記入賞開口側から見て左右に並べて配置し、前記移動体は、前記内部領域同士の軸間距離と同間隔で配される一対の邪魔板を有しており、前記第１位置では前記入賞開口と前記第２の内部領域との間に前記邪魔板の一方を割り込ませて該第２の内部領域の前方のみを全面的に遮り、前記第２位置では前記入賞開口と前記第１の内部領域との間に前記邪魔板の他方を割り込ませて該第１の内部領域の前方のみを全面的に遮ることにより、前記第１位置では前記入賞開口を通過した遊技球を前記第２の内部領域に流入し難くし、前記第２位置では前記入賞開口を通過した遊技球を前記第１の内部領域に流入し難くする構成とするのは、上記した内部領域に流入する球数の比（８：２、２：８）の実現に適している。
【００１４】
【発明の実施の形態】
次に、本発明の実施例により発明の実施の形態を説明する。
【００１５】
【実施例１】
入賞装置に該当するアタッカー１０は、アタッカー１０を遊技盤（図示しない）に固定するための部材であり、またアタッカー１０を構成する各部を支持する部材でもあるベース板１１を備えている。
【００１６】
ベース板１１には大入賞口となる入賞開口１２が設けられ、その左右には普通入賞口用の穴１２ａ、１２ｂが設けられている。これらの穴１２ａ、１２ｂの前面には、それぞれ外体１３ａ、１４ａと内体１３ｂ、１４ｂからなる球受１３、１４が取り付けられている（図示は片側のみ）。
【００１７】
入賞開口１２には、開閉板に該当するシャッター１５が背面側から差し込まれている。シャッター１５はの軸１６は軸受溝１７に挿入され、その軸受溝１７に内部体２５の突起２４が嵌合して軸１６の脱落が防止されている。シャッター１５は軸１６を中心にして起立位置と倒伏位置とに往復変位可能で、起立位置では入賞開口１２を閉鎖し、倒伏位置では開放する。また、倒伏位置では入賞開口１２の前方に突出するので、上方から落下してくる遊技球を受け止めて、これを入賞開口１２に導き入れる働きをする。シャッター１５には梃子受１８が備わっており、この梃子受１８を介して作用する力により起立位置と倒伏位置とに往復駆動される（その駆動機構については後述）。
【００１８】
シャッター１５の背後側にはステージ２０が配される。ステージ２０の前面側には段差２１が設けられており、この段差２１にシャッター１５の後縁を受容している。つまり、シャッター１５の脱落を防止するとともに揺動変位の軸がずれるのを防止している。ステージ２０の中央部２２は手前（入賞開口１２側）が高く奥が低い傾斜となり、その左右部分２３はそれぞれ中央部２２側を低くする傾斜となっている。ステージ２０は、その背後の内部体２５によって保持されている。
【００１９】
内部体２５には入賞開口１２に対面する位置に受入室２６が設けられ、ステージ２０はこの受入室２６に収容されている。受入室２６の奥には内壁２７に開口された門部２７ａにて連通する振分室２８が設けられている。振分室２８の内部は、仕切２９によって左右に分割されており、その床部３０にはそれぞれＵ字状の切欠である落下口３１、３２が設けられている。また仕切２９の両サイドにはセンサ保持溝３３、３４が設けられている。仕切２９の背後部分は、門部２７ａの左右及び門部２７ａの上側の３箇所で内壁２７の背面に連接され、また落下口３１、３２の間で床部３０の後縁に連接されている十字部３５にて支持されている。
【００２０】
内壁２７の背面からは床部に平行にセンサロック３７、３８が延出されている。センサロック３７、３８と床部３０との距離はセンサ保持溝３３、３４の幅とほぼ等しく、センサ保持溝３３、センサロック３７及び床部３０にてＶスイッチ３９を保持し、センサ保持溝３４、センサロック３８及び床部３０にてカウントスイッチ４０を保持している。センサロック３７、３８はスイッチ３９、４０の装着に際しては弾性変形し、装着後は先端のフックにてスイッチ３９、４０の脱落を防止する。Ｖスイッチ３９及びカウントスイッチ４０を装着した状態では、スイッチ３９、４０の上面は仕切２９の上面よりもわずかに低い位置になり、また仕切２９の上面はステージ２０の上面よりもわずかに低い位置になっている。
【００２１】
したがって、入賞開口１２を通過してステージ２０上に流入した遊技球は、ステージ２０から直接または仕切２９上を通ってスイッチ３９、４０の上面に転動してくる。そして、スイッチ３９、４０の上面から通過口３９ａ、４０ａを通り、落下口３１、３２から落下する。遊技球は通過口３９ａ、４０ａを通過する際にスイッチ３９、４０を作動させることで検出される。これら通過口３９ａ、４０ａがそれぞれ第１の内部領域と第２の内部領域に該当する。
【００２２】
内部体２５の背後の正面から見て右側になる部分にはシャッター１５を駆動するための梃子部材４２、その支持ピン４３、それらをカバーする梃子カバー４４が取り付けられている。また、梃子カバー４４の背後にはサポート４５を介して背後体４６に支持される開閉ソレノイド４７が、駆動方向（プランジャの移動方向）を垂直方向にして配されている。そして、嵌合部４８ａを開閉ソレノイド４７のプランジャヘッド４７ａに嵌合させた中継部材４８のピン部４８ｂが梃子カバー４４を貫通して梃子部材４２に接続されている。これにより開閉ソレノイド４７のオン、オフに応じてシャッター１５を開閉（オンでシャッター１５を倒しオフで起立させることが）できる。
【００２３】
内部体２５の背後の正面から見て左側になる部分にはサポート４９を介して切換ソレノイド５０が取り付けられている。切換ソレノイド５０の駆動方向（プランジャの移動方向）は水平方向であり、開閉ソレノイド４７の駆動方向とは９０度ずれている。
【００２４】
切換ソレノイド５０のプランジャヘッド５０ａにはＬ字状の中継部材５１の嵌合部５１ａが嵌合されている。この中継部材５１のピン穴５１ｂを第１梃子５３の主軸５３ｃが貫通しており、主軸５３ｃから延出されたピン部５３ａは移動体５４の第１梃子穴５４ａに挿入されている。また、第１梃子５３の軸穴５３ｂは内部体２５の背面に立設された第１軸ピン５５に外嵌されており、第１梃子５３は第１軸ピン５５を中心にして回動自在である。
【００２５】
また、第１軸ピン５５と対照位置に立設された第２軸ピン５６が、第１梃子５３と対をなす第２梃子５７の軸穴５７ｂに挿通されており、第２梃子５７は第２軸ピン５６を中心にして回動自在である。そして、第２梃子５７のピン部５７ａは、移動体５４の第２梃子穴５４ｂに挿入されている。
【００２６】
移動体５４は第１梃子穴５４ａ及び第２梃子穴５４ｂが連設されているスライド板５８を水平方向に沿わせる姿勢で配され、その前方側（入賞開口１２側）の縁からは一対の邪魔板５９、６０が垂下されている。邪魔板５９、６０同士の間隔は、スイッチ３９、４０の通過口３９ａ、４０ａの軸間距離とほぼ等しく、また遊技球の直径の２倍を越えている。邪魔板５９、６０の横断面の形状はくさび状であり、前面（入賞開口１２側の面）は、そこに衝突した遊技球を邪魔板５９、６０同士の間隔側へ導くテーパ面５９ａ、６０ａとなっている。
【００２７】
移動体５４はスライド板５８を背後体４６の庇部６１ａ、６１ｂに載せる状態で支持され、庇部６１ａ、６１ｂの上面に沿って（摺動するわけではない）左右に移動できる。また、庇部６１ａ、６１ｂの間隔は十字部３５の縦部３５ａの幅をわずかに上回り、ここに縦部３５ａを挿通させ、自身は縦部３５ａと左右の腕部３５ｂ、３５ｃとの間に入り込んだ状態となっている。つまり、腕部３５ｂ、３５ｃ、庇部６１ａ、６１ｂ及び縦部３５ａにて、Ｖスイッチ３９及びカウントスイッチ４０の上方をドーム状に覆っている。
【００２８】
図５，６に示すように、切換ソレノイド５０がオフのとき（プランジャヘッド５０ａが突き出し位置のとき）には移動体５４は図において左側（通過口４０ａ側）とされ、邪魔板５９がステージ２０から通過口３９ａに至る経路を遮る位置になるので、入賞開口１２からステージ２０上に流入した遊技球は通過口４０ａ方向に導かれる。しかし、邪魔板５９は通過口３９ａの前方のみを遮り仕切２９の前方は遮っていないから、ステージ２０から仕切２９上を通って通過口３９ａに流入できる。本実施例で実験したところ、邪魔板５９が図５，６の位置にある場合には、入賞開口１２から流入した遊技球の内ほぼ８０％が通過口４０ａに流入しほぼ２０％が通過口３９ａに流入した。
【００２９】
一方、図７，８に示すように、切換ソレノイド５０がオンのとき（プランジャが引き込まれたとき）には邪魔板６０がステージ２０から通過口４０ａに至る経路を遮る位置になるので、入賞開口１２からステージ２０上に流入した遊技球は通過口３９ａ方向に導かれる。しかし、邪魔板６０は通過口４０ａの前方のみを遮り仕切２９の前方は遮っていないから、ステージ２０から仕切２９上を通って通過口４０ａに流入できる。本実施例で実験したところ、邪魔板６０が図７，８の位置にある場合には、入賞開口１２から流入した遊技球の内ほぼ８０％が通過口３９ａに流入しほぼ２０％が通過口４０ａに流入した。
【００３０】
いずれの場合も、邪魔板５９、６０のテーパ面５９ａ、６０ａが遊技球を邪魔板５９、６０の間に効率よく誘導した。
以上のように、このアタッカー１０は、移動体５４を左右に移動させることにより、入賞開口１２から流入した遊技球すなわち入賞球を通過口３９ａまたは通過口４０ａに優先的に誘導できる。
【００３１】
このため、アタッカー１０の開放初期から特定領域（通過口３９ａ）に１球以上の入賞球が流入するまでは移動体５４を図７，８に示す位置（通過口４０ａには流入しにくい状態）とし、通過口３９ａに入賞球が流入した後に移動体５４を図５，６に示す位置（通過口３９ａには流入しにくい状態）とすれば、入賞開口１２の開放初期に入賞した遊技球は主に特定領域とされている通過口３９ａに向かうことになるので、いずれか１球が特定領域に流入する可能性は高い。よって、継続開放の可能性が高まるから遊技者の要望に応じることができる。その後に移動体５４の位置を変えて特定領域とされる通過口３９ａには流入しにくい状態にすればよい。
【００３２】
このアタッカー１０は、一対の邪魔板６０を入賞開口１２と通過口４０ａとの間に割り込ませることで通過口４０ａへ流入しにくくし（このとき他方の邪魔板５９は入賞開口１２から通過口３９ａへ向かう球の移動を邪魔しない位置になっている。）、他方の邪魔板５９を入賞開口１２と通過口３９ａとの間に割り込ませることで通過口３９ａへ流入しにくくする（このとき邪魔板６０は入賞開口１２から通過口４０ａへ向かう球の移動を邪魔しない位置となっている。）ので、簡単な構成で済む。
【００３３】
移動体５４を駆動する切換ソレノイド５０の駆動力を伝達する中継部材５１が第１梃子５３の主軸５３ｃに連結されているので、切換ソレノイド５０のプランジャの変位を第１梃子５３にて増幅できるから、切換ソレノイド５０のストロークが小さくて済む。つまり小型化できる。
【００３４】
また、邪魔板５９、６０の入賞開口１２側の面は、この面に衝突した遊技球を邪魔板５９、６０同士の間隔側へ導くテーパ面５９ａ、６０ａとされているので、入賞開口１２を通過した遊技球が邪魔板５９、６０の入賞開口１２側に停滞するおそれはない。
【００３５】
しかも、邪魔板５９、６０同士の間隔は２個の遊技球が同時に通過可能な間隔であるから、邪魔板５９、６０同士の間隔で遊技球が詰まるおそれもない。
【００３６】
【実施例２】
入賞装置に該当するアタッカー１１０は、アタッカー１１０を遊技盤（図示しない）に固定するための部材であり、またアタッカー１１０を構成する各部を支持する部材でもある取付板１１１を備えている。
【００３７】
取付板１１１には大入賞口となる入賞開口１１２が開設されている突出部１１１ａと突出部１１１ａを取り囲むフランジ部１１１ｂとが設けられており、図１４に示すように突出部１１１ａはフランジ部１１１ｂの表面よりも遊技者側に突出している。
【００３８】
入賞開口１１２には、開閉板に該当するシャッター１１５が背面側から差し込まれている。シャッター１１５は、一対の軸１１６を取付板１１１の軸受溝１１７に挿入されており、その軸受溝１１７に内部体１２５の突起１２４が嵌合して軸１１６の脱落が防止されている。
【００３９】
シャッター１１５は、両軸１１６を中心にして起立位置と倒伏位置とに往復揺動可能で、起立位置では入賞開口１１２を閉鎖し、倒伏位置では開放する。また、倒伏位置では入賞開口１１２の前方に突出するので、上方から落下してくる遊技球を受け止めて、これを入賞開口１１２に導き入れる働きをする。シャッター１１５には梃子受１１８が備わっており、この梃子受１１８を介して作用する力により起立位置と倒伏位置とに往復駆動される（駆動機構については後述）。
【００４０】
軸１１６の軸芯Ｃは、図１４に示すように取付板１１１の表面よりも手前（遊技者側）とされており、本実施例の場合取付板１１１のフランジ部１１１ｂの板厚Ｔ１が２ｍｍであり軸芯Ｃは取付板１１１の背面（遊技盤の表面）から３ｍｍの距離にある。なお、突出部１１１ａの突出量は３ｍｍで取付板１１１の背面から突出部１１１ａの表面までの距離Ｔ２は５ｍｍである。
【００４１】
軸１１６の軸芯Ｃが取付板１１１の背面（すなわち遊技盤の表面）から３ｍｍ遊技者側にあるので、軸芯Ｃからガラス板までの距離を小さくできる。これに応じて軸芯Ｃからシャッター１１５の先端までの寸法を小さくできるから、シャッター１１５の該寸法に対応する入賞開口１１２の開口高さを小さくできる。本実施例の場合入賞開口１１２の開口高さは約１８．４ｍｍで、従来品（出願人の製品）と比較して約３ｍｍ小さくなっている。この結果、入賞開口１１２が設けられている部分の上下寸法も小さくできる。本実施例の場合、図１３のＤ−Ｄ線による取付板１１１の断面の上下寸法は３８ｍｍであり、従来品よりも約３ｍｍ小さくなっている。
【００４２】
また、シャッター１１５は起立して入賞開口１１２を閉鎖する状態では突出部の内部に収容され、その外面（倒伏させたときに下側になる面）は入賞開口１１２に露出されてはいるが突出部よりも突き出てはいない。
シャッター１１５の背後側にはステージ１２０が配される。ステージ１２０の前面側には段差１２１が設けられている。この段差１２１はシャッター１１５の後縁部（軸よりもステージ１２０側の部分）との干渉を避けるために設けられている。ステージ１２０の中央部１２２は手前（入賞開口１１２側）が高く奥が低い傾斜となり、その左右部分１２３はそれぞれ中央部１２２側を低くする傾斜となっている。ステージ１２０は、その背後の内部体１２５によって保持されている。
【００４３】
内部体１２５には入賞開口１１２に対面する位置に受入室１２６が設けられ、ステージ１２０はこの受入室１２６に収容されている。受入室１２６の奥に配されている内壁１２７には門部１２７ａが開口されており、その奥には門部１２７ａにて受入室１２６と連通する振分部１２８が設けられている。
【００４４】
振分部１２８は横仕切１３０にて上下に分割され、横仕切１３０の下側部分は縦仕切１２９によって左右に分割されている。横仕切１３０には落下口１３１、１３２が設けられ、縦仕切１２９の左右はそれぞれ切欠状になっている。また縦仕切１２９の両サイドにはセンサ保持溝１３３、１３４が設けられており、それぞれＶスイッチ１３９、カウントスイッチ１４０を保持している。これらＶスイッチ１３９及びカウントスイッチ１４０の通過口１３９ａ、１４０ａはそれぞれ落下口１３１、１３２に対応した位置になり、遊技球が落下口１３１から通過口１３９ａを通って、また落下口１３２から通過口１４０ａを通って落下できる。遊技球は通過口１３９ａ、１４０ａを通過する際にスイッチ１３９、１４０を作動させることで検出される。これら通過口１３９ａ、１４０ａがそれぞれ第１の内部領域と第２の内部領域に該当する。
【００４５】
内部体１２５の背後の正面側から見て右側になる部分にはシャッター１１５を駆動するための機構（開閉機構）が配されている。この開閉機構は、内部体１２５の背面に立設された支持ピン１４３、支持ピン１４３にて軸支される梃子部材１４２、これをカバーする梃子カバー１４４、駆動源となる開閉ソレノイド１４７、開閉ソレノイド１４７を支持するサポート１４５によって構成されている。
【００４６】
梃子部材１４２は軸穴１４２ａ、Ｃ字状の保持部１４２ｂ及びピン部１４２ｃを備えている。軸穴１４２ａは支持ピン１４３に外嵌されており、梃子部材１４２は支持ピン１４３を中心にして回動自在である。保持部１４２ｂはシャッター１１５の梃子受１１８をくわえるようにして保持しており、ピン部１４２ｃは梃子カバー１４４の穴１４４ａを貫通している。開閉ソレノイド１４７のプランジャヘッド１４７ａにはＬ字状の中継部材１４８が取り付けられており、その長穴１４８ａに梃子部材１４２のピン部１４２ｃが挿通されている。これにより、開閉ソレノイド１４７のオン、オフに応じてシャッター１１５を開閉（オンでシャッター１１５を倒しオフで起立させることが）できる。
【００４７】
内壁１２７を挟んでこの開閉機構とは反対側になる位置には、横仕切１３０上に載置された移動体１５４を左右に往復駆動するための往復駆動機構が配されている。なお、移動体１５４の下面には４箇所の突起１５４ａが設けられておりこれら突起１５４ａのみが横仕切１３０に接触している。
【００４８】
往復駆動機構は、内壁１２７の背面に立設された軸ピン１５５、軸ピン１５５に軸支されたスライド梃子１５３、駆動源となる切換ソレノイド１５０、切換ソレノイド１５０を支持するサポート１４９によって構成されている。
スライド梃子１５３は、軸穴１５３ｂ、主軸１５３ｃ及びピン部１５３ａを備えている。軸穴１５３ｂは軸ピン１５５に外嵌されており、スライド梃子１５３は軸ピン１５５を中心にして回動自在である。
【００４９】
切換ソレノイド１５０のプランジャヘッド１５０ａにはＬ字状の中継部材１５１が取り付けられており、その長穴１５１ａにスライド梃子１５３の主軸１５３ｃが挿通されている。そして、主軸１５３ｃから延出されたピン部１５３ａが移動体１５４の上面に立設された梃子穴１５４ｂに挿通されている。
これにより、切換ソレノイド１５０のオン、オフに応じて移動体１５４を左右にスライドさせることができる。
【００５０】
移動体１５４には横長の通過穴１５８が設けられている。この通過穴１５８の短径は遊技球の直径を上回っており、遊技球が通過できる。長径はスイッチ１３９、１４０の通過口１３９ａ、１４０ａの軸間距離よりも十分に長い。また、移動体１５４の前方側（入賞開口１１２側）の縁からは一対の邪魔板１５９、１６０が立設されている。邪魔板１５９、１６０同士の間隔は、スイッチ１３９、１４０の通過口１３９ａ、１４０ａの軸間距離とほぼ等しく、また遊技球の直径の２倍を越えている。邪魔板１５９、１６０の横断面の形状はくさび状であり、前面（入賞開口１１２側の面）は、そこに衝突した遊技球を邪魔板１５９、１６０同士の間隔側へ導くテーパ面１５９ａ、１６０ａとなっている。
【００５１】
そして、移動体１５４を覆うようにして背後体１４６が配されている。背後体１４６には一対のスライドサポート１６１ａ、１６１ｂが備わっている。これらスライドサポート１６１ａ、１６１ｂは横仕切１３０とほぼ一連の面を形成し、左右にスライドした際に横仕切１３０からはみ出した移動体１５４を支える。また、背後体１４６とステージ１２０とで移動体１５４の前後方向の移動を規制している。
【００５２】
移動体１５４は切換ソレノイド１５０のオン、オフに応じて左右にスライドさせられるが、その際に通過穴１５８はスイッチ１３９、１４０の通過口１３９ａ、１４０ａの上方を移動する。
切換ソレノイド１５０がオンのとき（プランジャを引き込んでいるとき）には、邪魔板１６０がステージ１２０から通過口１４０ａに至る経路を遮り、邪魔板１５９がステージ１２０から通過口１３９ａに至る経路より退去した位置になる。このとき、通過穴１５８の邪魔板１６０側の端１５８ｃは通過口１４０ａを移動体１５４に投影した領域とほぼ整合する位置にあり、通過穴１５８から通過口１４０ａへの遊技球の移動を阻害しない。また、通過穴１５８の邪魔板１５９側の端１５８ｂは通過口１３９ａを移動体１５４に投影した領域から十分に外れた位置にある。
【００５３】
一方、切換ソレノイド１５０がオフのとき（プランジャが突き出されているとき）には、邪魔板１５９がステージ１２０から通過口１３９ａに至る経路を遮り、邪魔板１６０がステージ１２０から通過口１４０ａに至る経路より退去した位置になる。このとき、通過穴１５８の邪魔板１５９側の端１５８ｂは通過口１３９ａを移動体１５４に投影した領域とほぼ整合する位置にあり、通過穴１５８から通過口１３９ａへの遊技球の移動を阻害しない。また、通過穴１５８の邪魔板１６０側の端１５８ｃは通過口１４０ａを移動体１５４に投影した領域から十分に外れた位置にある。
【００５４】
こうした構成であるので、切換ソレノイド１５０がオンのときには入賞開口１１２からステージ１２０上に流入した遊技球は通過口１３９ａ方向に導かれる。しかし、邪魔板１６０は通過口１４０ａの前方のみを遮り、縦仕切１２９の上方を遮るわけではないから、遊技球がステージ１２０から縦仕切１２９の上方を通って通過穴１５８から通過口１４０ａに流入できる。本実施例で実験したところ、この状態では入賞開口１１２から流入した遊技球の内ほぼ８０％が通過口１３９ａに流入しほぼ２０％が通過口１４０ａに流入した。
【００５５】
一方、切換ソレノイド１５０がオフのときには入賞開口１１２からステージ１２０上に流入した遊技球は通過口１４０ａ方向に導かれる。しかし、邪魔板１５９は通過口１３９ａの前方のみを遮り、縦仕切１２９の上方を遮るわけではないから、遊技球がステージ１２０から縦仕切１２９の上方を通って通過穴１５８から通過口１３９ａに流入できる。本実施例で実験したところ、この状態では入賞開口１１２から流入した遊技球の内ほぼ８０％が通過口１４０ａに流入しほぼ２０％が通過口１３９ａに流入した。
【００５６】
いずれの場合も、邪魔板１５９、１６０のテーパ面１５９ａ、１６０ａが遊技球を邪魔板１５９、１６０の間に効率よく誘導した。
以上のように、このアタッカー１１０は、移動体１５４を左右に移動させることにより、入賞開口１１２から流入した遊技球すなわち入賞球を通過口１３９ａまたは通過口１４０ａに優先的に誘導できる。
【００５７】
このため、アタッカー１１０の開放初期から特定領域（通過口１３９ａ）に１球以上の入賞球が流入するまでは移動体１５４を図１３（ｂ）に示す位置（通過口１４０ａには流入しにくい状態）とし、通過口１３９ａに入賞球が流入した後に移動体１５４を図１３（ｄ）に示す位置（通過口１３９ａには流入しにくい状態）とすれば、入賞開口１１２の開放初期に入賞した遊技球は主に特定領域とされている通過口１３９ａに向かうことになるので、いずれか１球が特定領域に流入する可能性は高い。よって、継続開放の可能性が高まるから遊技者の要望に応じることができる。その後に移動体１５４の位置を変えて特定領域とされる通過口１３９ａには流入しにくい状態にすればよい。
【００５８】
このアタッカー１１０は、一対の邪魔板１６０を入賞開口１１２と通過口１４０ａとの間に割り込ませることで通過口１４０ａへ流入しにくくし（このとき他方の邪魔板１５９は入賞開口１１２から通過口１３９ａへ向かう球の移動を邪魔しない位置になっている。）、他方の邪魔板１５９を入賞開口１１２と通過口１３９ａとの間に割り込ませることで通過口１３９ａへ流入しにくくする（このとき邪魔板１６０は入賞開口１１２から通過口１４０ａへ向かう球の移動を邪魔しない位置となっている。）ので、簡単な構成で済む。
【００５９】
また、邪魔板１５９、１６０の入賞開口１１２側の面は、この面に衝突した遊技球を邪魔板１５９、１６０同士の間隔側へ導くテーパ面１５９ａ、１６０ａとされているので、入賞開口１１２を通過した遊技球が邪魔板１５９、１６０の入賞開口１１２側に停滞するおそれはない。
【００６０】
しかも、邪魔板１５９、１６０同士の間隔は２個の遊技球が同時に通過可能な間隔であるから、邪魔板１５９、１６０同士の間隔で遊技球が詰まるおそれもない。
実施例にしたがって本発明の実施の形態を説明したが、本発明はこれらの例に限定されるものではない。

TECHNICAL FIELD OF THE INVENTION
The present invention belongs to the technical field of a ball-and-ball game machine represented by a pachinko machine, and more particularly, to a winning device mounted on a ball and ball game machine.
[0002]
[Prior art]
Ball game machines such as pachinko machines are often equipped with a variable winning device that changes between a state where winning is difficult and a state where winning is easy. One type of such variable winning devices is a form called an attacker. This attacker has an opening / closing plate that can be reciprocated between a standing position and a falling position, a closing plate when the opening / closing plate is in the standing position, opening when the opening / closing plate is in the falling position, and passing over a falling opening / closing plate when open. It has a winning opening through which a game ball has flowed in, and is often used as a so-called big winning opening that is opened at the time of a so-called big hit.
[0003]
In the case of using as a special winning opening, there is a game mode in which a special region and a non-special region are set therein, and the special winning opening is continuously opened when a winning game ball passes through the special region. In this case, since there is a need for uncertainty as to whether or not to continue opening, the probability that a winning ball passes through the special area during one opening period of the special winning opening is suppressed to some extent. At present, this probability is defined as approximately 1/3, and the number of winning balls in one opening period of the special winning opening is about 10 balls, and about 3 balls among them pass through the special area. It is a calculation.
[0004]
On the other hand, for the player, the higher the probability that the winning ball passes through the special area, the better, and it is desired that the winning ball be practically 100%. For this reason, in the past, a structure was adopted in which most of the winning prize balls were guided to the special area. Also, in order to reduce the apparent probability, when one ball entered the special area, the entrance was closed, or the entrance of the special area was closed. The ball was retained and prevented the following from flowing into the special area.
[0005]
[Problems to be solved by the invention]
However, in a structure that guides most of the winning balls to the special area, there is no point in setting the special area and the non-special area, and an entrance that cannot enter the special area is provided to prevent the inflow to the special area. There was a risk that it would be out of the essence of ball game.
[0006]
Means for Solving the Problems and Effects of the Invention
The winning device according to claim 1 isA mounting plate fixed to the game board by bringing the back surface into contact with the surface of the game board, and a pair of shafts inserted in bearing grooves of the mounting plate as a center.An opening / closing plate capable of reciprocating displacement between an upright position and a falling position, closed when the opening / closing plate is at the upright position, and opened when at the falling position, and A prize device comprising: a prize opening for allowing a game ball to pass therethrough; and first and second internal regions arranged to allow a game ball having passed through the prize opening to flow into any of the prize openings.The mounting plate, which is provided with a protrusion protruding toward the player side from the surface of the flange surrounding the periphery and having the winning opening opened, and the axis of the shaft is positioned closer to the player than the surface of the flange. Said opening and closing plate,Reciprocating between the first position and the second position along a direction interposed between the winning opening and the first and second internal regions and crossing a path from the winning opening to the first and second internal regions.Move and saidAt the first position, it is difficult for game balls that have passed through the prize opening to flow into the second internal area, and at the second position, it is difficult for game balls that have passed through the prize opening to flow into the first internal area. Moving body and driving means for reciprocatingly driving the moving bodyAndSince the moving body is provided, by displacing the moving body between the first position and the second position, it is possible to make it difficult to flow into the second internal region or to flow into the first internal region. Conversely, the winning ball can be guided to the first internal area or the second internal area.
[0007]
For example, when the first internal area is the above-described specific area and the second internal area is the above-mentioned non-specific area, the moving object is moved to the first position (non-specific area) until one or more winning balls flow into the specific area. The moving body may be set to the second position (a state where it is difficult to flow into the specific area) after the winning ball has flowed into the specific area. In this case, since the game balls that have been won in the early stage of opening the winning opening mainly go to the specific area, there is a high possibility that any one ball will flow into the specific area. Therefore, the possibility of continuous opening is increased, so that it is possible to meet the player's request. Thereafter, the moving body may be set to the second position (a state where it is difficult to flow into the specific area).
[0008]
However, when the moving body is at the first position, it is difficult to flow into the non-specific area (second internal area), and when it is at the second position, it is difficult to flow into the specific area (first internal area). In any case, it does not mean that the non-specific area (second internal area) or the specific area (first internal area) is closed (making the game ball impossible to flow) in any case. There is no danger that there is no point in setting the special area, and there is no danger that the essence of the ball game will be removed by creating an entrance that cannot enter the ball.
[0009]
When the moving body is at the first position, the number of balls flowing into the first internal area: the number of balls flowing into the second internal area = approximately 8: 2. The number of spheres flowing into the region: the number of spheres flowing into the second internal region may be set to be approximately 2: 8. In this way, it can be assumed that some of the winning balls that have passed through the winning opening will enter the specific area around the first or second ball, and about two of the remaining 8 to 9 balls will be in the specific area. Can be assumed to flow. That is, about 3 out of 10 balls flow into the specific area, and a probability of approximately 1/3 can be realized.
[0010]
As described in claim 3,The first internal region and the second internal region are arranged side by side with respect to the winning opening side with an axial distance exceeding twice the diameter of the game ball, and the moving body is arranged between the internal regions. And a pair of baffles arranged at the same distance from each other. At the first position, one of the baffles is interrupted between the winning opening and the second internal region, and only the front of the second internal region is provided. In the second position, the other of the baffle plates is interrupted between the winning opening and the first internal region to completely block only the front of the first internal region. It is suitable for realizing the ratio (8: 2, 2: 8) of the number of spheres flowing into the region.
[0011]
By making one of the pair of baffles intervene between the winning opening and the second internal region, it is difficult to flow into the second internal region (at this time, the other baffle plate moves from the winning opening to the first internal region). A position where the movement of the ball is not obstructed), and the other baffle is interrupted between the winning opening and the first internal area to make it difficult to flow into the first internal area. (A position that does not obstruct the movement of the sphere from the winning opening toward the second internal area)Therefore, the configuration is simple.
[0012]
The winning device according to claim 1 isSince the axis of the opening / closing plate is closer to the player than the surface of the flange portion, the distance from the axis to the glass plate can be reduced. Accordingly, the dimension from the axis to the tip of the opening / closing plate can be reduced, so that the opening height of the winning opening corresponding to the dimension of the opening / closing plate can be reduced. As a result, the vertical dimension of the portion where the winning opening is provided can be reduced.
[0013]
Bearing grooveClaim 2It may be provided on the back side of the protruding portion as shown in FIG.
Further, as described in claim 3, in the prize winning device of claim 1 or 2,The first internal region and the second internal region are arranged side by side with respect to the winning opening side at an inter-axis distance exceeding twice the diameter of the game ball, and the moving body is arranged between the internal regions. And a pair of baffles arranged at the same distance as the distance between the axes. At the first position, one of the baffles is inserted between the winning opening and the second internal area. Only the front of the second internal region is completely blocked, and the other of the baffle plate is interrupted between the winning opening and the first internal region at the second position, so as to be in front of the first internal region. In the first position, the game balls that have passed through the winning opening are less likely to flow into the second internal area, and the game balls that have passed through the winning opening in the second position. Configuration that makes it difficult to flow into the first internal areaIs suitable for realizing the ratio (8: 2, 2: 8) of the number of spheres flowing into the above-mentioned internal region.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described with reference to examples of the present invention.
[0015]
Embodiment 1
The attacker 10 corresponding to the winning device is provided with a base plate 11 that is a member for fixing the attacker 10 to a game board (not shown) and also a member that supports each part constituting the attacker 10.
[0016]
The base plate 11 is provided with a winning opening 12 serving as a large winning opening, and holes 12a and 12b for normal winning openings are provided on the left and right sides thereof. Ball receivers 13 and 14 including outer bodies 13a and 14a and inner bodies 13b and 14b are attached to the front surfaces of these holes 12a and 12b, respectively (only one side is shown).
[0017]
A shutter 15 corresponding to an opening and closing plate is inserted into the winning opening 12 from the back side. The shaft 16 of the shutter 15 is inserted into the bearing groove 17, and the projection 24 of the inner body 25 is fitted into the bearing groove 17 to prevent the shaft 16 from falling off. The shutter 15 is reciprocally displaceable about a shaft 16 between a standing position and a falling position, and closes the winning opening 12 at the standing position and opens at the lying position. Further, since the protruding portion projects in front of the winning opening 12 at the falling position, it functions to receive a game ball falling from above and guide it into the winning opening 12. The shutter 15 is provided with a lever receiver 18, and is reciprocated between a standing position and a falling position by a force acting via the lever receiver 18 (the driving mechanism will be described later).
[0018]
A stage 20 is arranged behind the shutter 15. A step 21 is provided on the front side of the stage 20, and the rear edge of the shutter 15 is received in the step 21. In other words, the shutter 15 is prevented from falling off and the axis of the swing displacement is prevented from being shifted. The center portion 22 of the stage 20 has a higher slope near the winning opening 12 and a lower slope, and its left and right portions 23 have slopes lowering the center portion 22 side. The stage 20 is held by an internal body 25 behind it.
[0019]
A receiving chamber 26 is provided in the inner body 25 at a position facing the winning opening 12, and the stage 20 is accommodated in the receiving chamber 26. At the back of the receiving chamber 26, there is provided a sorting chamber 28 communicating with a gate 27a opened to the inner wall 27. The interior of the sorting chamber 28 is divided into right and left by a partition 29, and its floor 30 is provided with U-shaped cutouts 31 and 32, respectively. Sensor holding grooves 33 and 34 are provided on both sides of the partition 29. The rear part of the partition 29 is connected to the back of the inner wall 27 at three places on the left and right sides of the gate 27a and above the gate 27a, and is connected to the rear edge of the floor 30 between the drops 31 and 32. It is supported by the cross portion 35.
[0020]
From the back surface of the inner wall 27, sensor locks 37, 38 extend in parallel with the floor. The distance between the sensor locks 37, 38 and the floor 30 is substantially equal to the width of the sensor holding grooves 33, 34, and the V switch 39 is held by the sensor holding grooves 33, the sensor lock 37, and the floor 30. The count switch 40 is held by the sensor lock 38 and the floor 30. The sensor locks 37, 38 are elastically deformed when the switches 39, 40 are mounted, and after mounting, the hooks at the tips prevent the switches 39, 40 from falling off. When the V switch 39 and the count switch 40 are mounted, the upper surfaces of the switches 39 and 40 are slightly lower than the upper surface of the partition 29, and the upper surface of the partition 29 is slightly lower than the upper surface of the stage 20. Has become.
[0021]
Therefore, the game balls that have flowed into the stage 20 through the winning opening 12 roll on the upper surfaces of the switches 39 and 40 directly from the stage 20 or through the partition 29. Then, the light passes from the upper surfaces of the switches 39 and 40, passes through the passage ports 39a and 40a, and falls from the fall ports 31 and 32. A game ball is detected by operating the switches 39 and 40 when passing through the passage openings 39a and 40a. These passages 39a and 40a correspond to a first internal area and a second internal area, respectively.
[0022]
A lever member 42 for driving the shutter 15, a support pin 43, and a lever cover 44 for covering the lever member 42 are attached to a portion on the right side when viewed from the front behind the inner body 25. Behind the lever cover 44, an opening / closing solenoid 47 supported by a back body 46 via a support 45 is disposed with the driving direction (moving direction of the plunger) being vertical. The pin portion 48b of the relay member 48 having the fitting portion 48a fitted to the plunger head 47a of the opening / closing solenoid 47 passes through the lever cover 44 and is connected to the lever member 42. Thus, the shutter 15 can be opened and closed in accordance with the on / off state of the opening / closing solenoid 47 (the shutter 15 can be turned down when turned on and raised when turned off).
[0023]
A switching solenoid 50 is attached via a support 49 to a portion on the left side when viewed from the front behind the inner body 25. The driving direction of the switching solenoid 50 (the moving direction of the plunger) is the horizontal direction, and is shifted by 90 degrees from the driving direction of the opening / closing solenoid 47.
[0024]
The fitting portion 51a of the L-shaped relay member 51 is fitted to the plunger head 50a of the switching solenoid 50. The main shaft 53c of the first lever 53 passes through the pin hole 51b of the relay member 51, and the pin portion 53a extending from the main shaft 53c is inserted into the first lever hole 54a of the moving body 54. Further, the shaft hole 53b of the first lever 53 is externally fitted to a first shaft pin 55 erected on the back surface of the inner body 25, and the first lever 53 is rotatable around the first shaft pin 55. It is.
[0025]
A second shaft pin 56 erected at a position opposite to the first shaft pin 55 is inserted into a shaft hole 57b of a second lever 57 paired with the first lever 53, and the second lever 57 is It is rotatable about a biaxial pin 56. The pin portion 57a of the second lever 57 is inserted into the second lever hole 54b of the moving body 54.
[0026]
The moving body 54 is disposed in such a manner that a slide plate 58 provided with the first lever hole 54a and the second lever hole 54b is arranged in a horizontal direction, and a pair of moving members 54 are formed from a front edge thereof (a winning opening 12 side). The baffle plates 59 and 60 are suspended. The distance between the baffle plates 59 and 60 is substantially equal to the distance between the axes of the passage ports 39a and 40a of the switches 39 and 40, and exceeds twice the diameter of the game ball. The cross-sectional shape of the baffle plates 59 and 60 is wedge-shaped, and the front surface (the surface on the side of the winning opening 12) has tapered surfaces 59a and 60a that guide the game balls colliding there to the gap side between the baffle plates 59 and 60. It has become.
[0027]
The moving body 54 is supported with the slide plate 58 placed on the eaves 61a, 61b of the back body 46, and can move left and right (not slide) along the upper surfaces of the eaves 61a, 61b. In addition, the interval between the eaves 61a and 61b is slightly larger than the width of the vertical portion 35a of the cross portion 35, and the vertical portion 35a is inserted here, and the space between the vertical portion 35a and the left and right arm portions 35b and 35c. It has entered. In other words, the arms 35b and 35c, the eaves 61a and 61b, and the vertical portion 35a cover the V switch 39 and the count switch 40 in a dome shape.
[0028]
As shown in FIGS. 5 and 6, when the switching solenoid 50 is off (when the plunger head 50a is in the protruding position), the moving body 54 is on the left side (the side of the passage 40a) in the figure, and the baffle plate 59 is The game ball that has flowed into the stage 20 from the prize opening 12 is guided toward the passage 40a since the path from the winning opening 12 to the passage 39a is blocked. However, since the baffle plate 59 blocks only the front of the passage 39a and does not block the front of the partition 29, the baffle 59 can flow from the stage 20 through the partition 29 to the passage 39a. As a result of an experiment in this embodiment, when the baffle plate 59 is located at the position shown in FIGS. 5 and 6, approximately 80% of the game balls flowing from the winning opening 12 flow into the passage 40a and approximately 20% pass through the passage 40a. 39a.
[0029]
On the other hand, as shown in FIGS. 7 and 8, when the switching solenoid 50 is on (when the plunger is retracted), the baffle plate 60 is at a position where it blocks the path from the stage 20 to the passage opening 40a. The game ball flowing into the stage 20 from 12 is guided toward the passage 39a. However, since the baffle plate 60 blocks only the front of the passage 40a and does not block the front of the partition 29, the baffle 60 can flow from the stage 20 through the partition 29 into the passage 40a. According to the experiment performed in this embodiment, when the baffle plate 60 is located at the position shown in FIGS. 7 and 8, approximately 80% of the game balls flowing from the winning opening 12 flow into the passage 39a and approximately 20% pass through the passage 39a. 40a.
[0030]
In each case, the tapered surfaces 59a, 60a of the baffle plates 59, 60 efficiently guided the game ball between the baffle plates 59, 60.
As described above, the attacker 10 can preferentially guide the game ball, that is, the winning ball, which has flowed from the winning opening 12 to the passing opening 39a or the passing opening 40a by moving the moving body 54 right and left.
[0031]
For this reason, the moving body 54 is moved to the position shown in FIGS. 7 and 8 (a state where it is difficult to flow into the passage 40a) from the initial opening of the attacker 10 until one or more winning balls flow into the specific area (the passage 39a). If the moving body 54 is placed at the position shown in FIGS. 5 and 6 after the winning ball has flowed into the passing port 39a (in a state where it is difficult to flow into the passing port 39a), the gaming ball won in the early stage of opening the winning opening 12 Since the ball is mainly directed to the passage port 39a which is regarded as the specific area, there is a high possibility that any one ball will flow into the specific area. Therefore, the possibility of continuous opening is increased, so that it is possible to meet the player's request. Thereafter, the position of the moving body 54 may be changed so that the moving body 54 hardly flows into the passage port 39a which is a specific area.
[0032]
In this attacker 10, the pair of baffle plates 60 are inserted between the winning opening 12 and the passage opening 40a to make it difficult to flow into the passage opening 40a (at this time, the other baffle plate 59 is moved from the winning opening 12 to the passage opening 39a). It is in a position that does not hinder the movement of the sphere toward.), And the other baffle plate 59 is interposed between the winning opening 12 and the passage opening 39a to make it difficult to flow into the passage opening 39a (at this time, the baffle plate). 60 is a position that does not hinder the movement of the sphere from the winning opening 12 toward the passage 40a.) Therefore, a simple configuration is sufficient.
[0033]
Since the relay member 51 that transmits the driving force of the switching solenoid 50 that drives the moving body 54 is connected to the main shaft 53c of the first lever 53, the displacement of the plunger of the switching solenoid 50 can be amplified by the first lever 53. Thus, the stroke of the switching solenoid 50 can be small. That is, the size can be reduced.
[0034]
The surfaces of the baffle plates 59 and 60 on the prize opening 12 side are formed as tapered surfaces 59a and 60a for guiding the game balls colliding with this surface to the space between the baffle plates 59 and 60. There is no danger that the passed game balls will stagnate on the winning opening 12 side of the baffle plates 59, 60.
[0035]
Moreover, since the interval between the baffle plates 59 and 60 is a distance at which two game balls can pass at the same time, there is no possibility that the game balls are clogged at the interval between the baffle plates 59 and 60.
[0036]
Embodiment 2
The attacker 110 corresponding to the winning device has a mounting plate 111 which is a member for fixing the attacker 110 to a game board (not shown) and which is a member for supporting each part constituting the attacker 110.
[0037]
The mounting plate 111 is provided with a protruding portion 111a having a winning opening 112 serving as a big winning opening and a flange portion 111b surrounding the protruding portion 111a. As shown in FIG. Projecting toward the player from the surface of the player.
[0038]
A shutter 115 corresponding to an opening / closing plate is inserted into the winning opening 112 from the back side. The shutter 115 has a pair of shafts 116 inserted into bearing grooves 117 of the mounting plate 111, and the protrusions 124 of the inner body 125 are fitted into the bearing grooves 117 to prevent the shafts 116 from falling off.
[0039]
The shutter 115 is reciprocally swingable about an axle 116 between a standing position and a falling position. The shutter 115 closes the winning opening 112 at the standing position and opens at the falling position. In the lying position, since it protrudes forward of the winning opening 112, it functions to receive a game ball falling from above and guide it into the winning opening 112. The shutter 115 is provided with a lever receiver 118, and is reciprocally driven between a standing position and a falling position by a force acting via the lever receiver 118 (a driving mechanism will be described later).
[0040]
As shown in FIG. 14, the axis C of the shaft 116 is closer to the player than the surface of the mounting plate 111 (the player side). In this embodiment, the thickness T1 of the flange portion 111b of the mounting plate 111 is 2 mm. And the axis C is at a distance of 3 mm from the back surface of the mounting plate 111 (the surface of the game board). The protrusion amount of the protrusion 111a is 3 mm, and the distance T2 from the back surface of the mounting plate 111 to the surface of the protrusion 111a is 5 mm.
[0041]
Since the axis C of the shaft 116 is 3 mm away from the rear surface of the mounting plate 111 (that is, the surface of the game board), the distance from the axis C to the glass plate can be reduced. Since the dimension from the axis C to the tip of the shutter 115 can be reduced accordingly, the opening height of the winning opening 112 corresponding to the dimension of the shutter 115 can be reduced. In the case of the present embodiment, the opening height of the winning opening 112 is about 18.4 mm, which is about 3 mm smaller than the conventional product (the applicant's product). As a result, the vertical dimension of the portion where the winning opening 112 is provided can be reduced. In the case of this embodiment, the vertical dimension of the cross section of the mounting plate 111 along the line DD in FIG. 13 is 38 mm, which is about 3 mm smaller than the conventional product.
[0042]
When the shutter 115 stands up and closes the winning opening 112, the shutter 115 is housed inside the protruding portion, and its outer surface (the surface that becomes lower when it is folded down) is exposed to the winning opening 112 but protrudes. Does not protrude beyond the department.
A stage 120 is provided behind the shutter 115. A step 121 is provided on the front side of the stage 120. The step 121 is provided to avoid interference with the rear edge of the shutter 115 (the portion closer to the stage 120 than the axis). The central portion 122 of the stage 120 has a high slope near the prize opening 112 and a low depth, and the left and right portions 123 have a slope decreasing the central portion 122 side. Stage 120 is held by an internal body 125 behind it.
[0043]
A receiving chamber 126 is provided in the inner body 125 at a position facing the winning opening 112, and the stage 120 is accommodated in the receiving chamber 126. A gate 127a is opened in the inner wall 127 disposed in the back of the receiving chamber 126, and a distribution unit 128 communicating with the receiving chamber 126 at the gate 127a is provided in the back.
[0044]
The distribution unit 128 is vertically divided by a horizontal partition 130, and the lower part of the horizontal partition 130 is divided into right and left by a vertical partition 129. Drop openings 131 and 132 are provided in the horizontal partition 130, and the left and right sides of the vertical partition 129 are notched. Further, sensor holding grooves 133 and 134 are provided on both sides of the vertical partition 129, and hold a V switch 139 and a count switch 140, respectively. The passages 139a and 140a of the V switch 139 and the count switch 140 are located at positions corresponding to the fallouts 131 and 132, respectively, so that the game ball passes from the fallout 131 through the passage 139a and from the fallout 132 to the passage 140a. Can fall through. A game ball is detected by operating the switches 139 and 140 when passing through the passage openings 139a and 140a. These passages 139a and 140a correspond to a first internal area and a second internal area, respectively.
[0045]
A mechanism (opening / closing mechanism) for driving the shutter 115 is provided in a portion on the right side when viewed from the front behind the inner body 125. This opening / closing mechanism includes a support pin 143 erected on the back of the inner body 125, a lever member 142 pivotally supported by the support pin 143, a lever cover 144 covering the same, an opening / closing solenoid 147 serving as a driving source, and an opening / closing solenoid. 147 is supported by a support 145.
[0046]
The lever member 142 includes a shaft hole 142a, a C-shaped holding portion 142b, and a pin portion 142c. The shaft hole 142a is fitted around the support pin 143, and the lever member 142 is rotatable about the support pin 143. The holding portion 142b holds the lever receiver 118 of the shutter 115 so as to hold it, and the pin portion 142c passes through the hole 144a of the lever cover 144. An L-shaped relay member 148 is attached to the plunger head 147a of the opening / closing solenoid 147, and the pin 142c of the lever member 142 is inserted into the elongated hole 148a. Thus, the shutter 115 can be opened and closed according to the on / off state of the opening / closing solenoid 147 (the shutter 115 can be turned down when turned on and raised when turned off).
[0047]
At a position opposite to the opening / closing mechanism with the inner wall 127 interposed therebetween, a reciprocating drive mechanism for reciprocatingly driving the moving body 154 mounted on the horizontal partition 130 left and right is disposed. Note that four projections 154 a are provided on the lower surface of the moving body 154, and only these projections 154 a are in contact with the horizontal partition 130.
[0048]
The reciprocating drive mechanism includes a shaft pin 155 erected on the back surface of the inner wall 127, a slide lever 153 supported by the shaft pin 155, a switching solenoid 150 serving as a driving source, and a support 149 supporting the switching solenoid 150. I have.
The slide lever 153 includes a shaft hole 153b, a main shaft 153c, and a pin 153a. The shaft hole 153b is fitted around the shaft pin 155, and the slide lever 153 is rotatable about the shaft pin 155.
[0049]
An L-shaped relay member 151 is attached to the plunger head 150a of the switching solenoid 150, and the main shaft 153c of the slide lever 153 is inserted into the elongated hole 151a. A pin 153a extending from the main shaft 153c is inserted into a lever hole 154b provided upright on the upper surface of the moving body 154.
Thereby, the moving body 154 can be slid left and right according to the on / off state of the switching solenoid 150.
[0050]
The moving body 154 is provided with a horizontally long passage hole 158. The short diameter of the passage hole 158 exceeds the diameter of the game ball, and the game ball can pass through. The major axis is sufficiently longer than the distance between the axes of the passage ports 139a and 140a of the switches 139 and 140. In addition, a pair of baffle plates 159 and 160 are provided upright from the front edge (the winning opening 112 side) of the moving body 154. The distance between the baffle plates 159 and 160 is substantially equal to the distance between the axes of the passage ports 139a and 140a of the switches 139 and 140, and exceeds twice the diameter of the game ball. The cross-sectional shape of the baffle plates 159 and 160 is wedge-shaped, and the front surface (the surface on the prize opening 112 side) has tapered surfaces 159a and 160a that guide the game balls colliding there to the gap side between the baffle plates 159 and 160. It has become.
[0051]
The back body 146 is disposed so as to cover the moving body 154. The back body 146 includes a pair of slide supports 161a and 161b. The slide supports 161a and 161b form a substantially series of surfaces with the horizontal partition 130, and support the moving body 154 that protrudes from the horizontal partition 130 when sliding left and right. Further, the back body 146 and the stage 120 regulate the movement of the moving body 154 in the front-rear direction.
[0052]
The moving body 154 is slid left and right according to the on / off state of the switching solenoid 150. At this time, the passing hole 158 moves above the passing ports 139a and 140a of the switches 139 and 140.
When the switching solenoid 150 is on (when the plunger is retracted), the baffle plate 160 blocks the path from the stage 120 to the passage port 140a, and the baffle plate 159 retreats from the path from the stage 120 to the passage port 139a. Position. At this time, the end 158c of the passage hole 158 on the side of the baffle plate 160 is located at a position substantially matching the region where the passage opening 140a is projected on the moving body 154, and does not hinder the movement of the game ball from the passage hole 158 to the passage opening 140a. . The end 158b of the passage hole 158 on the side of the baffle plate 159 is located sufficiently away from the area where the passage opening 139a is projected on the moving body 154.
[0053]
On the other hand, when the switching solenoid 150 is turned off (when the plunger is protruding), the baffle plate 159 blocks the path from the stage 120 to the passage port 139a, and the baffle plate 160 blocks the path from the stage 120 to the passage port 140a. You will be in a more departed position. At this time, the end 158b of the passage hole 158 on the side of the baffle plate 159 is located at a position substantially matching the area where the passage opening 139a is projected on the moving body 154, and does not hinder the movement of the game ball from the passage hole 158 to the passage opening 139a. . The end 158c of the passage hole 158 on the side of the baffle plate 160 is located sufficiently away from the area where the passage opening 140a is projected on the moving body 154.
[0054]
With such a configuration, when the switching solenoid 150 is on, the game ball flowing into the stage 120 from the winning opening 112 is guided toward the passage 139a. However, since the baffle plate 160 blocks only the front of the passage 140a and does not block the upper part of the vertical partition 129, the game ball flows from the stage 120 through the upper part of the vertical partition 129 into the passage opening 158 through the passage hole 158. it can. According to an experiment conducted in this embodiment, in this state, approximately 80% of the game balls flowing from the winning opening 112 flowed into the passage 139a, and approximately 20% flowed into the passage 140a.
[0055]
On the other hand, when the switching solenoid 150 is off, the game ball flowing into the stage 120 from the winning opening 112 is guided toward the passage 140a. However, since the baffle plate 159 blocks only the front of the passage 139a and does not block the upper part of the vertical partition 129, the game ball flows from the stage 120 above the vertical partition 129 into the passage hole 158 through the passage hole 158. it can. According to an experiment conducted in this embodiment, in this state, approximately 80% of the game balls flowing from the winning opening 112 flowed into the passage 140a, and approximately 20% flowed into the passage 139a.
[0056]
In each case, the tapered surfaces 159a, 160a of the baffle plates 159, 160 efficiently guided the game ball between the baffle plates 159, 160.
As described above, the attacker 110 can preferentially guide the game ball, that is, the winning ball, which has flowed from the winning opening 112 to the passing opening 139a or the passing opening 140a by moving the moving body 154 left and right.
[0057]
For this reason, the moving body 154 is moved from the initial stage of the attacker 110 to the position shown in FIG. 13B (the state in which it does not easily flow into the passage 140a) until one or more winning balls flow into the specific area (the passage 139a). ), The moving body 154 is positioned as shown in FIG. 13D after the winning ball has flowed into the passage 139a (in a state where it is difficult to flow into the passage 139a). Since the sphere mainly goes to the passage port 139a which is a specific area, there is a high possibility that any one sphere will flow into the specific area. Therefore, the possibility of continuous opening is increased, so that it is possible to meet the player's request. Thereafter, the position of the moving body 154 may be changed so that the moving body 154 hardly flows into the passage port 139a which is a specific area.
[0058]
In this attacker 110, the pair of baffles 160 is inserted between the winning opening 112 and the passage opening 140a to make it difficult to flow into the passage opening 140a (at this time, the other baffle plate 159 is moved from the winning opening 112 to the passage opening 139a. It is in a position that does not hinder the movement of the sphere toward.), And the other baffle plate 159 is inserted between the winning opening 112 and the passage opening 139a to make it difficult to flow into the passage opening 139a (at this time, the baffle plate) 160 is a position that does not hinder the movement of the sphere from the winning opening 112 to the passage 140a.) Therefore, a simple configuration is sufficient.
[0059]
The surfaces of the baffle plates 159 and 160 on the prize opening 112 side are formed as tapered surfaces 159a and 160a that guide the game balls colliding with this surface to the interval side between the baffle plates 159 and 160. There is no danger that the passed game balls will stagnate on the winning opening 112 side of the baffles 159, 160.
[0060]
In addition, the interval between the baffle plates 159 and 160 is an interval at which two game balls can pass at the same time, and there is no possibility that the game balls are clogged at the interval between the baffle plates 159 and 160.
Although the embodiments of the present invention have been described according to the examples, the present invention is not limited to these examples.
