【０００１】
【発明の属する技術分野】
本発明は、２つの回転体を１つの球で停止させて当たり外れ抽選を行うパチンコ機の遊技部品に関する。
【０００２】
【従来の技術】
円盤面の周方向に沿って複数の遊技球落下孔を設けた抽選用回転体を上下２段に設け、２つの抽選用回転体を用いて当たり外れ抽選を行う抽選装置（遊技部品）を備えたパチンコ機が知られている（例えば、特許文献１参照）。この抽選装置によれば１／２０８の確率の当たり外れ抽選を行える。
【０００３】
【特許文献１】
特開平９−９９１３９号公報
【０００４】
【発明が解決しようとする課題】
特許文献１では、遊技球が２つの抽選用回転体を経由するのに時間がかかり、当たり外れ抽選結果が得られるまでに時間がかかる。
本発明は、当たり外れ抽選での当たりの発生する確率の分母を大きくでき、かつ、球が抽選部に取り込まれてから当たり外れ抽選結果が得られるまでの時間を短縮できて、抽選遊技を可及的に早く処理でき、遊技性を向上することができる、球の絡みで当たり外れ抽選を行う遊技部品を提供することを目的とする。
【０００５】
【課題を解決するための手段】
本発明は、遊技盤への取付ベースと取付ベースに取り付けられた抽選部とを備えたパチンコ機の遊技部品において、抽選部が取付ベースの前面に回転可能にかつ１個の球の直径よりも小さな周面間隔を隔てて取り付けられた２つの回転体と、各回転体の前面に周方向に分離配置された複数の抽選要素と、各回転体の周面にそれぞれの抽選要素と対応して１個の球の直径よりも大きな対向間隔を形成し得る形態に設けられた切欠部と、取付ベースの裏面に取り付けられて球を上方から下方に向けて引き込む方向に２つの回転体を回転駆動する駆動源と、２つの回転体における１個の球の直径よりも小さい周面間隔の下方で取付ベースの前面に設けられた球ストッパと、２つの回転体の周面間隔から１個の球が駆動源による２つの回転体の回転駆動で各回転体の切欠部に取り込まれて球ストッパで受け止められた後に切欠部と噛み合うことで２つの回転体の回転駆動を停止させた１個の球が対応する２つの回転体における切欠部の抽選要素の組み合わせ態様で当たり外れ抽選を行う抽選処理手段とを備えたので、当たり外れ抽選での当たりの発生する確率の分母を大きくでき、かつ、球が抽選部に取り込まれてから当たり外れ抽選結果が得られるまでの時間を短縮できて、抽選遊技を可及的に早く処理でき、遊技性を向上することができる、球の絡みで当たり外れ抽選を行う遊技部品が得られる。
また、駆動源の動力を回転体に伝達する機構には駆動源から回転体への動力伝達を遮断するクラッチ部が形成されたものとしたので、２つの回転体の停止後の回転体及び駆動源の負担を軽減できる。
また、クラッチ部がカム体とカムフォロワとカムフォロワ取付体と押圧手段とを備え、カム体が回転体又は駆動源の一方に連結され、カムフォロワ取付体が回転体又は駆動源の他方に連結され、カムフォロワが回転体の径方向と平行な方向に移動可能となるようカムフォロワ取付体に取り付けられる一方、カム体がカムフォロワを係止して駆動源の動力を回転体に伝達する動力伝達係止部とカムフォロワをカム周面上で摺動させる動力遮断部とを備え、押圧手段がカムフォロワ取付体を押圧してカムフォロワを動力遮断部から動力伝達係止部に移動させる構成としたので、２つの回転体の停止直後に動力伝達を遮断できて、２つの回転体の停止後の回転体及び駆動源の負担をさらに軽減でき、また、カムフォロワの位置を動力遮断状態と動力伝達状態とにスムーズに移行させることができる。
また、カム体には動力伝達係止部と動力遮断部との間でカムフォロワを移動させる経路が複数形成された構成としたので、カムフォロワの移動が確実となり、回転体への動力伝達及び動力遮断を確実に行わせることができる。
また、カムフォロワを動力伝達係止部から動力遮断部に移動させる方向の弾性をカムフォロワ取付体に付与する弾性体が取付ベースに取り付けられた構成としたので、２つの回転体の停止直後に動力伝達を速やかに遮断できるようになり、２つの回転体の停止後における回転体及び駆動源の負担をさらに軽減できる。
また、取付ベースには球ストッパで受け止められた球を取付ベースの前側から裏側に誘導排出する球逃がし孔が設けられたので、回転体を停止させた球を遊技盤の裏側に排出することができ、遊技領域の下方に設けられた入賞部品に球が再び入賞しないようにできる。
また、取付ベースの裏側には球逃がし孔を経由して誘導排出された球を検出する球検出器が設けられ、球検出器からの検出信号に基いてカムフォロワを動力遮断部から動力伝達係止部に移動させるよう押圧手段を作動させたので、球と回転体との噛み合いが解消されたことを示す上記検出信号を検出してから動力伝達状態にすることで、動力伝達状態となった時の球による駆動源や回転体への負荷を確実に排除できる。
また、球ストッパが取付ベースに前後移動可能に設けられ、球ストッパが駆動機構を備え、回転体が回転している場合に駆動機構で球ストッパを取付ベースより前方に突出させ、球ストッパで受け止められた球で回転体が停止した後に駆動機構で球ストッパを取付ベースの裏側に後退させることで球を遊技領域外に排出させる構成としたので、回転体を停止させた球を遊技領域の下方に設けられた入賞部品に球が再び入賞しないようにできるとともに、動力を遮断しない構成も可能となる。
また、回転体の回転角度を検出する回転角度検出手段を備え、抽選処理手段が停止した回転体の回転角度情報を回転角度検出手段から入力した後にクラッチ部を動力遮断状態としたので、動力を遮断しない構成やクラッチ部として電磁クラッチを用いた構成も可能となる。

【発明の実施の形態】
実施形態１
図１は遊技部品が取り付けられた遊技盤を備えたパチンコ機の正面図、図２は遊技部品の正面拡大図、図３は図２のＡ−Ａ断面図、図４は遊技部品を裏側から見た斜視図、図５はクラッチ部のカム体とカムフォロワとの関係を示す斜視図、図６はクラッチ部の動力伝達時と動力遮断時の状態を示す説明図、図７は制御ブロック図である。
図１に示すように、パチンコ機の遊技盤１の前面である遊技盤面２にはガイドレール３が設けられ、このガイドレール３で囲まれた領域と遊技盤面２の前側に設けられたガラス等の透視性パネル４との間で遊技球Ｐ（以下単に「球」という）が飛び交う遊技領域５が形成されている。遊技領域５における遊技盤面２の中央には本発明の遊技部品としての抽選装置６が設けられ、遊技盤面２において抽選装置６の左右の位置には入賞により後述の左右開閉体１５，１５を開閉させるための球通過型あるいは球取込み型の入賞部品７が設けられ、遊技盤面２において入賞部品７の下方の位置には入賞部品７への入賞結果を表示する表示装置７ａが設けられている。また、遊技盤面２において抽選装置６の下方の位置には可変入賞部品８が設けられている。９は遊技機枠、１０は上皿、１１は下皿、１２は球発射操作装置である。
【０００７】
抽選装置６は、図２に示すように、遊技盤面２への取付ベース１３の前面１４に、一対の左右開閉体１５，１５で構成された始動入賞口部１６、球保留部１７、球送り機構１８、抽選部１９を備える。即ち、始動入賞口部１６の真下には球保留部１７の球保留通路１７Ａが形成されており、この球保留通路１７Ａの下方には球送り機構１８が設けられ、球送り機構１８の下方には抽選部１９が設けられる。球送り機構１８は円形平板上の球送り用回転体２０を備える。この球送り用回転体２０は円板面が取付ベース１３の前面１４と平行に対向するよう配置されている。球送り用回転体２０の円周面２１には１８０度の間隔を隔てて２つの切欠部２２が形成されていて、自然流下により球保留通路１７Ａを経由した球が切欠部２２に入り込んだ状態で球送り用回転体２０が回転することにより球が抽選部１９に送られる。球保留通路１７Ａを形成する通路壁２３から延長して球送り用回転体２０の円周面２１と対向する球送り機構隔壁２４が設けられており、球送り用回転体２０の円周面２１と球送り機構隔壁２４との間の間隔は球１個分の直径よりも短い間隔に形成されている。球送り用回転体２０の下方には抽選部１９への通路２５を形成する通路壁２６が球送り機構隔壁２４より延長して設けられている。通路壁２６から延長して抽選部１９の上側を閉塞する隔壁２７が設けられ、この隔壁２７から延長し抽選部１９の左右及び下側を閉塞して抽選部１９を区画するとともに球保留通路１７Ａの通路壁２３の上端や中途部に延長して球送り機構隔壁２４，通路壁２３，隔壁２７との間に部品収容スペース２８を区画形成する外隔壁２９が設けられている。通路壁２３の右壁２３ａの中途部より右斜め下に傾斜して延長する外隔壁２９の部分２９ａとこの部分２９ａと平行に右壁２３ａの上端２３ｔより右斜め下に傾斜して設けられる隔壁３０とで球排出樋３１が形成されており、球排出樋３１の終端は終端壁３０ｅで塞がれていて、球排出樋３１の終端の部分の取付ベース１３及び遊技盤１には球を遊技盤１の裏側に排出するための排出孔１７ｈが形成され、この排出孔１７ｈを介して遊技盤１の裏側に導かれた球は図外の樋を介して回収される。従って、球保留通路１７Ａには所定の数の球しか保留されず（例えば図２に示すように３個しか保留されない）、所定数を超える球が球保留通路１７Ａに入ってきても球排出樋３１を介して遊技盤１の裏側に導かれて遊技領域外に排出される。尚、上記各壁の前面に透視性パネル蓋３２Ａが取り付けられ、透視性パネル蓋３２Ａにより球保留通路１７Ａ，球送り機構１８，抽選部１９，部品収容スペース２８の前面が塞がれている。部品収容スペース２８には図外の図柄表示器などを設けてもよい。また、通路壁２３の左壁２３ｂの上端２３ｕより左斜め下に延長する外隔壁２９の部分２９ｂにより、開閉体１５，１５間に入らなかった球が遊技領域５に導かれる。
【０００８】
一対の左右開閉体１５，１５を駆動するソレノイド３２等の駆動源は取付ベース１３の裏面１３ａに取り付けられたケーシング３３内に取り付けられており、一対の左右開閉体１５，１５はソレノイド３２の作動軸３４で駆動する操作部材３５により左右開閉体１５，１５の動力受軸３６を上下に移動することで左右開閉体１５，１５が回転中心軸３７を中心として回転して開閉動作する。
球送り用回転体２０を回転駆動させるステッピングモータ３８等の駆動源は取付ベース１３の裏面１３ａに取り付けられたケーシング３９内に取り付けられており、ステッピングモータ３８の回転力が球送り用回転体２０の円中心に接続された回転中心軸４０に伝達されて球送り用回転体２０が回転する。
【０００９】
抽選部１９は左右に円形平板状の抽選用回転体４１，４２を備える。これら抽選用回転体４１，４２は円板面が取付ベース１３と平行に対向するよう配置されて円中心を回転中心として回転するものである。これら抽選用回転体４１，４２は取付ベース１３の裏側に設けられたモータ４３（図４参照）等の駆動源により球を上方から下方に向けて引き込む方向、即ち、図２の矢印Ｒで示す方向に回転する。これら抽選用回転体４１，４２において遊技者側に対向する円板面である前面には円板面の回転中心４１ａ，４２ａから円周面４４に向けて延長する区切線４５により複数の抽選要素４６が区画されて分離配置されている。各抽選要素４６として例えば数字などの図柄が表示されている。各抽選要素４６に対応する円周面４４にはそれぞれ球が入り込む切欠部４７が形成されている。抽選用回転体４１，４２は球１個の直径より小さい周面間隔ａを隔てて横一列に並べて設置されている。即ち、それぞれの回転中心４１ａ，４２ａが水平線上に位置するように配置される。抽選用回転体４１，４２間においてそれぞれの回転中心４１ａ，４２ａを結んだ水平線上よりも下方の位置には取付ベース１３から前方に突出する球ストッパ４８が設けられており、これにより、通路２５の真下に設けられる球１個の直径より小さい周面間（間隔ａ）に球が自然流下し、この球１個の直径より小さい周面間の位置において球ストッパ４８により球が受け止められるよう構成されている。この場合、抽選部１９に球が送られてくると各抽選用回転体４１，４２間において１個の球の直径より大きな対向間隔で対向する２つの切欠部４７，４７に球が入り込んで球が球ストッパ４８の位置まで移動し、抽選用回転体４１，４２間に形成される球１個の直径より小さい周面間の位置で球が球ストッパ４８により受け止められる。この球ストッパ４８で受け止められた球が１個の球の直径より大きな対向間隔を形成する２つの抽選用回転体４１，４２の切欠部４７，４７と衝突して噛み合うことで各抽選用回転体４１，４２の回転が阻害され各抽選用回転体４１，４２が停止する。各抽選用回転体４１，４２を停止させた１個の球が対応する２つの各抽選用回転体４１，４２の切欠部４７，４７に対応した抽選要素４６，４６の組み合わせ態様により当たり外れ抽選が行われる。例えば、図２に示すように、各抽選用回転体４１，４２を停止させた１個の球が対応する切欠部４７，４７の抽選要素４６，４６が「１」，「１」のように揃うとこれが抽選処理手段としてのパチンコ機の制御装置５０で認識されることで当たりと判断され、可変入賞部品８の扉を頻繁に開閉する特別遊技状態とする。従って、各抽選用回転体４１，４２を停止させた１個の球が対応する切欠部４７，４７の２つの抽選要素４６，４６の組み合わせで当たり外れ抽選を行える。
【００１０】
なお、１つの抽選要素４６に複数の切欠部４７を対応させておいてもよい。この場合、複数の抽選要素４６を描いた薄葉体を円板面である前面に接着剤などで貼り付けて抽選用回転体４１，４２における抽選要素４６の表示を形成すれば、後に複数の切欠部４７のひとつひとつに対応する抽選要素４６を描いた薄葉体に貼り変えるようにすることで異なる抽選遊技を提供できるようになる。
【００１１】
図３，４に示すように、抽選用回転体４１，４２の回転中心の裏面には回転軸５１が連結され、この回転軸５１には当該回転軸５１の回転角度を検出するためのエンコーダ５２のスリット板５２ａが取り付けられており、かつ、後述するクラッチ部６０及びエンコーダ５２を収納するケーシング５３が取付ベース１３の裏面１３ａに取り付けられている。このケーシング５３に取り付けられた検出部取付体５４に発光素子及び受光素子を具備したエンコーダ５２の検出部５２ｂが取り付けられている。即ち、原点付きスリット板５２ａと発光素子及び受光素子から成る検出部５２ｂとで構成されたエンコーダ５２（即ち、抽選用回転体４１，４２の回転角度検出手段）が設けられている。回転軸５１とモータ４３の回転駆動力を伝達する伝達軸５５との間にはクラッチ部６０が設けられ、このクラッチ部６０により回転軸５１と伝達軸５５とが接続されて抽選用回転体４１，４２へ動力が伝達されるとともに回転軸５１と伝達軸５５とが切り離されて抽選用回転体４１，４２への動力伝達が遮断される。図４に示すようにモータ４３の駆動力は複数のギヤ５６，５７，５８，５９を介して伝達軸５５に伝達され、これにより各抽選用回転体４１，４２が図２に示すように球を上方から下方に向けて引き込む方向に回転する。抽選用回転体４１，４２の伝達軸５５，５５は出力側ギヤ５８，５９の軸受部６１に軸方向に移動可能でかつキー６２を介して出力側ギヤ５８，５９と一緒に回転するように連結されている。複数のギヤ５６，５７，５８，５９を収納する蓋ケース６３がケーシング５３に取り付けられている。
【００１２】
クラッチ部６０は回転軸５１の後端に設けられた円柱状のカム体６４と、伝達軸５５の前端に設けられた一端（前端）開放の円筒状のカムフォロワ取付体６５と、カムフォロワ取付体６５の前端側の周面に１８０度の間隔を隔てて取り付けられた２つのカムフォロワ６６と、カムフォロワ取付体６５の前後方向への移動をガイドするガイド体６７と、カムフォロワ取付体６５の前端側の周面より突出するフランジ６８とこのフランジの前面６８ａに対して所定間隔を隔てて対向するようガイド体６７に設けられた対向板７０との間に介在された弾性体としてのコイルスプリング７１と、ガイド体６７に取り付けられてフランジ６８を前方に押圧する押圧手段としてのソレノイド７２とを備える。ガイド体６７はケーシング５３内に取り付けられている。
【００１３】
カムフォロワ６６は図５，６に示すように、内鍔７３の一面より突出するように形成されたカムフォロワ本体７４と内鍔７３の他面よりカムフォロワ本体７４とは反対方向に延長するよう形成された軸部７５とこの軸部７５に挿着されるコイルスプリング７６と軸部７５の先端に取り付けられた外鍔７７とにより構成される。このカムフォロワ６６の取付けは、軸部７５にコイルスプリング７６を挿着した状態でカムフォロワ取付体６５に形成された孔７８を介してカムフォロワ取付体６５の筒の内側から軸部７５を外側に貫通させ、軸部７５の先端に外鍔７７を図外の止めねじなどで取り付ければよい。カムフォロワ取付体６５の筒内面における孔７８の周りには凹部７９が形成され、これにより、後述する動力遮断時に内鍔７３が凹部７９に嵌まり込んでカムフォロワ６６の姿勢が維持されるので、カムフォロワ本体７４がカム体６４の周面上をスムーズに移動する。また、カムフォロワ６６がコイルスプリング７６により抽選用回転体４１，４２の径方向と平行な方向に移動可能となるようカムフォロワ取付体６５に取り付けられているので、動力伝達を確実に行える。
【００１４】
図５に示すようにカム体６４の周面にはカムフォロワ本体７４を係止してモータ４３の動力を抽選用回転体４１，４２に伝達する動力伝達係止部８０とカムフォロワ本体７４をカム体６４の周面上で摺動させる動力遮断部８１とが形成され、カム体６４の動力伝達係止部８０と動力遮断部８１との間には動力伝達経路８２と動力遮断経路８３が形成されている。動力伝達係止部８０はカムフォロワ本体７４がコイルスプリング７６の弾性で嵌まり込んで係止する係止溝により形成される。この係止溝は２つのカムフォロワ６６に対応してカム体６４の周面において１８０度隔てた位置に形成されている。
【００１５】
動力伝達経路８２はカムフォロワ本体７４が摺動するカム体６４の周面である動力遮断部８１のどの位置からでもカムフォロワ本体７４を動力伝達係止部８０に導く経路である。
動力遮断経路８３は動力伝達係止部８０である係止溝からカム体６４の周方向に沿って延長した後にカム体６４の軸方向に延長して動力遮断部８１に到達するよう形成されたスロープ面で構成される。
【００１６】
動力遮断経路８３は具体的には図５に示すように動力伝達係止部８０である係止溝（一番低い部位Ａ）より高い面Ｂとこの面Ｂより高い面Ｃとが形成されており、この面Ｂから周方向にそって徐々に高くなっていくスロープ面ＢＣを経て面Ｃに至った後に面Ｂより低い動力遮断部８１である面Ｅに至るようにカム体６４に周面に形成された経路（即ち図５の経路▲１▼）あるいは面Ｂから面Ｅに直接到達する経路（即ち図５の経路▲２▼）である。面Ｅの高さは部位Ａの高さと同じでもよい。面Ｄは一番高い面であり、カムフォロワ本体７４は面Ｄと面Ｂあるいは面ＢＣとの間の段差壁ＤＸにより移動が規制される。
【００１７】
弾性体としての上記コイルスプリング７１は図６に示すように対向板７０より後方に突出する支持棒８４に嵌め込まれて位置決めされ、一端７１ａが対向板７０に取り付けられ、他端７１ｂがカムフォロワ取付体６５のフランジ６８の前面６８ａに接触していて、このコイルスプリング７１の弾性力がフランジ６８に付与されている。従って、抽選用回転体４１，４２の回転が停止してもカムフォロワ取付体６５は回転し続けるので、カムフォロワ６６がコイルスプリング７６に抗してカムフォロワ取付体６５側に移動してカムフォロワ本体７４が動力伝達係止部８０より外れる。カムフォロワ本体７４が動力伝達係止部８０から外れるとコイルスプリング７１の弾性によりカムフォロワ取付体６５が後方に押圧される。このとき、カムフォロワ本体７４は経路▲２▼を経由して動力遮断部８１としての面Ｅに到達するか、あるいは、周方向に移動しているときには面ＢＣと面Ｃとの間の段差壁Ｘに当接した状態から経路▲１▼を経由して動力遮断部８１に到達する。これにより、カムフォロワ本体７４は動力遮断部８１である面Ｅ上を摺動する状態となるので、動力伝達が遮断される。
【００１８】
一方、動力伝達経路８２は面Ｅ側における面Ｂと面Ｃとの段差壁Ｙを経由してカムフォロワ本体７４を動力伝達係止部８０に導く経路（即ち図５の経路▲３▼）あるいは動力遮断経路８３である経路▲１▼を逆にたどる経路（即ち図５の経路▲４▼）で構成される。ここで段差壁Ｙは２つの動力伝達係止部８０間の周囲領域に渡って連続して形成されている。従って、動力伝達状態とする際に押圧手段としてのソレノイド７２の作動軸７２ａを突出させてフランジ６８を前方に移動させることにより、カムフォロワ本体７４が動力遮断部８１（面Ｅ）のどこに位置していてもカムフォロワ本体７４は経路▲３▼かあるいは経路▲４▼を経由して確実に動力伝達係止部８０に導かれる。
【００１９】
したがって、クラッチ部６０により２つの抽選用回転体４１，４２の停止直後に動力伝達を遮断できるので、２つの抽選用回転体４１，４２及びモータ４３の負担を軽減できる。また、カムフォロワ６６の位置を動力伝達状態と動力遮断状態とにスムーズに移行させることができる。
また、動力伝達経路８２及び動力遮断経路８３により、抽選用回転体４１，４２への動力伝達及び動力遮断を確実に行える。特に動力伝達経路８２と動力遮断経路８３とをそれぞれ複数設けたので、カムフォロワ６６の移動が確実に行われ、動力伝達及び動力遮断動作がスムーズかつ確実となる。
また、動力遮断状態に移行させる際にカムフォロワ６６を動力伝達係止部８０から動力遮断部８１に移動させる方向の弾性をカムフォロワ取付体６５に付与するコイルスプリング７１を備えたので、２つの抽選用回転体４１，４２の停止直後に動力伝達を速やかに遮断できるようになり、２つの抽選用回転体４１，４２の停止後の抽選用回転体４１，４２及びモータ４３の負担をさらに軽減できる。また、コイルスプリング７６により動力伝達係止部８０に対するカムフォロワ本体７４の着脱動作がスムーズになり、動力伝達状態及び動力遮断状態にスムーズに移行できる信頼性の高いクラッチ部６０となる。
また、押圧手段としてのソレノイド７２を備えたので、カムフォロワ６６を動力遮断部８１から動力伝達係止部８０に確実に移動でき、動力伝達回復動作が確実となる。
【００２０】
また、取付ベース１３には球ストッパ４８で受け止められた球を取付ベース１３の前側から裏側に誘導排出する球逃がし孔８５（図２参照）が設けられており、この球逃がし孔８５に繋がる球排出樋８６（図３参照）が取付ベース１３の裏面１３ａに取り付けられ、球排出樋８６の終端はケーシングの球排出孔８７に繋がれている。これにより、抽選用回転体４１，４２を停止させた球を遊技盤１の裏側に排出することができ、遊技領域５の下方に設けられた入賞部品に球が再び入賞しないようにできる。球排出樋８６には球検出器９３が取り付けられている。
【００２１】
次に動作を説明する。球保留部１７に球が１個も保留されていない状態において、開閉体１５，１５間を球が通過すると球保留部１７の入口に設けられた球検出器９０により球通過が検出され、この検出信号が制御装置５０に送られて、制御装置５０の遊技制御部５０ａはモータ４３を駆動する。モータ４３が駆動されると、抽選用回転体４１，４２が回転する。尚、入賞部品７に球が入ったり通過したりすると、入賞部品７の球検出器９１で検出され、この検出信号が制御装置５０に送られて遊技制御部５０ａはソレノイド３２を駆動し開閉体１５，１５を開閉するので、球保留部１７に球が入り易くなる。なお、開閉体１５，１５としては常時閉塞の開閉体を用い、入賞部品７への入賞がない限り球保留部１７に球が入りえない構成としてもよい。また、クラッチ部６０が動力遮断状態となっているときには、ソレノイド７２を駆動してクラッチ部６０を動力伝達状態としてからモータ４３を駆動する。そして、ステッピングモータ３８を駆動して球送り用回転体２０を所定角度回転させる。尚、図１においては、球送り用回転体２０は切欠部２２，２２が上下に位置する状態にしか停止しない。従って、切欠部２２に球が入ると１８０度回転する。これにより、球は抽選部１９に送られる。この時、抽選部１９の入口に設けられた球検出器９２により球通過が検出され、この検出信号が制御装置５０に送られ、遊技制御部５０ａは後述する規定時間が経過するまで球送り用回転体２０を回転させない。抽選部１９に送られた球は２つの抽選用回転体４１，４２の切欠部４７，４７に入って球ストッパ４８により受け止められ、これにより、球が切欠部４７，４７と衝突して噛み合うことで上述したように２つの抽選用回転体４１，４２が停止する。この停止した際にエンコーダ５２，５２からの回転角度情報に基いて制御装置５０の抽選処理部５０ｂで当たり外れ抽選結果を得る。即ち、抽選用回転体４１，４２が停止した後はエンコーダ５２から検出パルスが送られてこないからこれを抽選用回転体停止検出部５０ｃで判断して抽選用回転体４１，４２の停止を検出できる。停止した２つの抽選用回転体４１，４２の回転軸５１，５１の回転角度はそれまでにエンコーダ５２から送られてきている検出パルスに基いて認識できるので、この認識した回転角度に基いて１個の球で停止した抽選用回転体４１，４２の切欠部に対応する抽選要素４６，４６がなんであるかを抽選要素認識部５０ｄで認識できる。そして、抽選要素４６，４６の組み合わせが当たりであるか外れであるかが当たり外れ判断部５０ｅで判断され、当たりであれば、遊技制御部５０ａは遊技機を特別遊技状態に制御する。抽選用回転体４１，４２が停止してもモータ４３は駆動され続けているので、抽選用回転体４１，４２が球に邪魔されて回転できず抽選用回転体４１，４２と回転軸５１，５１を介して接続されたカム体６４，６４も回転しないのに対して、モータ４３により回転し続ける伝達軸５５，５５に接続されたカムフォロワ取付体６５，６５は回転しようとするので、カムフォロワ６６，６６は図５の動力伝達係止部８０，８０から抜け出て面Ｂに移動してから経路▲１▼又は経路▲２▼を経由して動力遮断部８１（Ｅ面）に移動し、動力遮断部８１の面Ｅ上をカムフォロワ本体７４が摺動してカムフォロワ取付体６５は回転を続ける一方、カム体６４とカムフォロワ本体７４との係合は解除されているので、動力伝達が完全に遮断される。
実施形態１では、抽選用回転体４１，４２の停止直後にクラッチ部６０の動力遮断動作と抽選処理部５０ｂによる当たり外れ判断処理が並行して行われ、抽選用回転体４１，４２の回転停止から動力遮断までの時間が短くなるので、モータ４３及び抽選用回転体４１，４２の負担を少なくできる。
動力伝達が遮断されると、抽選用回転体４１，４２は無負荷状態となり、切欠部４７，４７と球との接触状態が解除されて球は球逃がし孔８５を介して球排出樋８６を経由して図外の球回収樋に回収される。この時、球排出樋８６の球検出器９３で球排出が検出され、この検出信号が制御装置５０に送られ、遊技制御部５０ａはこの検出信号を受けてからソレノイド７２を駆動する。この検出信号が制御装置５０に出力されたならば、球による抽選用回転体４１，４２の回転負荷大の状態が解除されたということであり、動力を伝達してもモータ４３の負荷が少ない状態である。従って、この検出信号を検出してから動力伝達状態にすることで動力伝達状態となったときの球によるモータ４３や抽選用回転体４１，４２への負荷を確実に解除できるのでモータ４３や抽選用回転体４１，４２の負担を少なくできる。ソレノイド７２を駆動すると作動軸７２ａが突出してカムフォロワ取付体６５を前方に押圧するので、カムフォロワ本体７４が図５の経路▲３▼又は経路▲４▼を経由して動力伝達係止部８０に嵌まり込んで、動力伝達状態となり、抽選用回転体４１，４２は再び回転する。この際、動力伝達状態に復帰した後に抽選用回転体４１，４２が１回転してエンコーダ５２がスリット板５２ａの原点を検出したならば、この検出信号が制御装置５０に送られ、これにより、球送り用回転体２０を所定角度回転させるようにする。即ち、抽選部１９の入口に設けられた球検出器９２により球通過が検出されてから、動力遮断状態から動力伝達状態に復帰した後にエンコーダ５２が原点を検出するまでの間を規定時間とし、規定時間内は球送り用回転体２０を回転させない。これにより、動力遮断後においても回転角度を正確に検出でき、制御装置５０は、１個の球が対応する２つの抽選要素４６，４６を正確に認識できるようになる。
【００２２】
実施形態２
また、上記では、固定の球ストッパ４８を用いた形態を説明したが、前後移動可能の球ストッパを用いてもよい。即ち、図外のソレノイドなどの駆動機構付きの球ストッパを取付ベース１３に取り付け、抽選用回転体４１，４２が回転している場合にソレノイドで球ストッパを取付ベース１３より前方に突出させ、抽選処理部５０ｂが停止した抽選用回転体４１，４２の回転角度情報をエンコーダ５２から入力した後にソレノイドで球ストッパを取付ベース１３の裏側に後退させてもよい。この場合、例えば球ストッパの前部に球を引っかけて球排出樋８６に導くための立上壁を設けておけば、球を遊技盤１の裏側に導けて遊技領域外に排出できる。本実施形態２の場合、実施形態１と同様にクラッチ部６０による動力伝達を遮断してもよいが、動力を遮断しない構成も可能となる。
【００２３】
実施形態３
電磁クラッチを用いて動力伝達及び動力遮断を行うようにしてもよい。この場合、例えば、抽選処理部５０ｂが停止した抽選用回転体４１，４２の回転角度情報をエンコーダ５２から入力した後に電磁クラッチを動力遮断状態とし、抽選処理部５０ｂが当たり外れ判断を行った後に電磁クラッチをつないで動力伝達状態とすればよい。
【００２４】
実施形態１〜３によれば、当たり外れ抽選での当たりの発生する確率の分母を大きくでき、かつ、球が抽選部１９に取り込まれてから当たり外れ抽選結果が得られるまでの時間を短縮できて、抽選遊技を可及的に早く処理でき、遊技性を向上することができる、球の絡みで当たり外れ抽選を行う遊技部品が得られる。
【００２５】
尚、抽選用回転体４１，４２に設ける抽選要素４６の数を多くすれば、１／数百程度の当たり確率の遊技機が得られる。また、抽選用回転体４１の抽選要素数をＺａ，抽選用回転体４２の抽選要素数をＺｂとし、抽選用回転体４１の回転速度をｎａ，抽選用回転体４２の回転速度をｎｂとした場合、Ｚａ／Ｚｂ及びＺｂ／Ｚａが整数にならず、かつ、（Ｚａ×ｎａ）／（Ｚｂ×ｎｂ）＝１になるように設定すれば（ただし、１抽選要素当たりの切欠部４７の数は一定とする）、全抽選要素の組み合わせが実現するので好ましいが、必ずしもこのように設定しなくてもよい。
また、上述したカム体を構成する円柱体にカムフォロワを設け、カムフォロワ取付体を構成する円筒体の内面をカム体としてもよい。即ち、カム体が回転体又は駆動源の一方に連結され、カムフォロワ取付体が回転体又は駆動源の他方に連結された構成とすればよい。

Further, since the cam follower 66 is attached to the cam follower attachment body 65 so as to be movable in the direction parallel to the radial direction of the lottery rotation bodies 41 and 42 by the coil spring 76, power transmission can be performed reliably.
[0014]
As shown in FIG. 5, the cam follower body 74 is locked to the peripheral surface of the cam body 64 to transmit the power of the motor 43 to the lottery rotating bodies 41 and 42 and the cam follower body 74 is connected to the cam body. 64 is formed, and a power transmission path 82 and a power cutoff path 83 are formed between the power transmission locking section 80 and the power cutoff section 81 of the cam body 64. ing. The power transmission locking portion 80 is formed by a locking groove in which the cam follower body 74 is fitted and locked by the elasticity of the coil spring 76. The locking grooves are formed at positions separated by 180 degrees on the peripheral surface of the cam body 64 corresponding to the two cam followers 66.
[0015]
The power transmission path 82 is a path for guiding the cam follower main body 74 to the power transmission locking section 80 from any position of the power cut-off section 81 that is the peripheral surface of the cam body 64 on which the cam follower main body 74 slides.
The power cutoff path 83 is formed so as to extend from the locking groove as the power transmission locking portion 80 along the circumferential direction of the cam body 64 and then extend in the axial direction of the cam body 64 to reach the power cutoff portion 81. Consists of a slope surface.
[0016]
Specifically, as shown in FIG. 5, the power cutoff path 83 is formed with a surface B higher than a locking groove (the lowest part A) which is the power transmission locking portion 80 and a surface C higher than the surface B. The cam body 64 has a circumferential surface that extends from the surface B through the slope surface BC that gradually increases along the circumferential direction to the surface C and then reaches the surface E that is a lower power cut-off portion 81 than the surface B. (Ie, route {circle around (1)} in FIG. 5) or a route directly reaching surface E from surface B (ie, route {circle around (2)} in FIG. 5). The height of the surface E may be the same as the height of the part A. The surface D is the highest surface, and the cam follower body 74 is restricted from moving by the stepped wall DX between the surface D and the surface B or the surface BC.
[0017]
As shown in FIG. 6, the coil spring 71 as an elastic body is fitted and positioned on a support bar 84 protruding rearward from the counter plate 70, one end 71a is attached to the counter plate 70, and the other end 71b is a cam follower mounting body. The flange 68 is in contact with the front surface 68 a of the flange 68, and the elastic force of the coil spring 71 is applied to the flange 68. Therefore, even if the rotation of the lottery rotating bodies 41 and 42 stops, the cam follower mounting body 65 continues to rotate. Therefore, the cam follower 66 moves toward the cam follower mounting body 65 against the coil spring 76 and the cam follower main body 74 is powered. It is disengaged from the transmission locking portion 80. When the cam follower body 74 is disengaged from the power transmission locking portion 80, the cam follower attachment body 65 is pressed backward by the elasticity of the coil spring 71. At this time, the cam follower main body 74 reaches the surface E as the power cut-off portion 81 via the path (2), or the step wall X between the surfaces BC and C when moving in the circumferential direction. It reaches the power cut-off part 81 via the route {circle around (1)} from the state where it abuts. As a result, the cam follower main body 74 is in a state of sliding on the surface E that is the power cut-off portion 81, so that the power transmission is cut off.
[0018]
On the other hand, the power transmission path 82 is a path for guiding the cam follower body 74 to the power transmission locking portion 80 via the step wall Y between the surface B and the surface C on the surface E side (that is, the path (3) in FIG. 5) or the power. The path (1), which is the blocking path 83, is reversely routed (that is, the path (4) in FIG. 5). Here, the step wall Y is formed continuously over the peripheral region between the two power transmission locking portions 80. Accordingly, when the power transmission state is established, the operating shaft 72a of the solenoid 72 as the pressing means is projected to move the flange 68 forward, so that the cam follower main body 74 is positioned at the power shut-off portion 81 (surface E). However, the cam follower main body 74 is reliably guided to the power transmission locking portion 80 via the path (3) or the path (4).
[0019]
Therefore, since the power transmission can be cut off immediately after the two lottery rotators 41 and 42 are stopped by the clutch unit 60, the burden on the two lottery rotators 41 and 42 and the motor 43 can be reduced. Further, the position of the cam follower 66 can be smoothly shifted between the power transmission state and the power cutoff state.
Further, the power transmission path 82 and the power cut-off path 83 can reliably transmit power to the lottery rotators 41 and 42 and cut off the power. In particular, since a plurality of power transmission paths 82 and power cutoff paths 83 are provided, the cam follower 66 is reliably moved, and power transmission and power cutoff operations are smooth and reliable.
Further, since the cam follower attachment body 65 is provided with a coil spring 71 in the direction in which the cam follower 66 is moved from the power transmission locking portion 80 to the power cut-off portion 81 when shifting to the power cut-off state, the cam follower mounting body 65 is provided. Immediately after the rotators 41 and 42 are stopped, power transmission can be quickly interrupted, and the burden on the lottery rotators 41 and 42 and the motor 43 after the two lottery rotators 41 and 42 are stopped can be further reduced. In addition, the coil spring 76 allows the cam follower body 74 to be attached to and detached from the power transmission locking portion 80 smoothly, thereby providing a highly reliable clutch portion 60 that can smoothly transition to the power transmission state and the power cutoff state.
Further, since the solenoid 72 as the pressing means is provided, the cam follower 66 can be reliably moved from the power cut-off portion 81 to the power transmission locking portion 80, and the power transmission recovery operation is ensured.
[0020]
Further, the mounting base 13 is provided with a ball escape hole 85 (see FIG. 2) for guiding and discharging the ball received by the ball stopper 48 from the front side to the back side of the mounting base 13, and the ball connected to this ball escape hole 85. A discharge rod 86 (see FIG. 3) is attached to the back surface 13a of the mounting base 13, and the end of the ball discharge rod 86 is connected to a ball discharge hole 87 of the casing. As a result, the balls with the lottery rotors 41 and 42 stopped can be discharged to the back side of the game board 1, and the balls can be prevented from winning again in the winning components provided below the game area 5. A ball detector 93 is attached to the ball discharge rod 86.
[0021]
Next, the operation will be described. In a state where no sphere is held in the sphere holding section 17, when a sphere passes between the opening and closing bodies 15, 15, the sphere detector 90 provided at the entrance of the sphere holding section 17 detects the passage of the sphere. The detection signal is sent to the control device 50, and the game control unit 50 a of the control device 50 drives the motor 43. When the motor 43 is driven, the lottery rotators 41 and 42 rotate. When a ball enters or passes the winning component 7, it is detected by the ball detector 91 of the winning component 7, and this detection signal is sent to the control device 50, and the game control unit 50a drives the solenoid 32 to open and close the opening / closing body. Since 15 and 15 are opened and closed, it becomes easy for the ball to enter the ball holding portion 17. In addition, as the opening / closing bodies 15, 15, a normally closed opening / closing body may be used so that a ball cannot enter the ball holding portion 17 unless a winning component 7 is won. Further, when the clutch unit 60 is in the power cut-off state, the solenoid 72 is driven to bring the clutch unit 60 into the power transmission state, and then the motor 43 is driven. Then, the stepping motor 38 is driven to rotate the ball feeding rotator 20 by a predetermined angle. In FIG. 1, the ball feeding rotator 20 stops only when the notches 22 are positioned vertically. Accordingly, when a sphere enters the notch 22, it rotates 180 degrees. As a result, the ball is sent to the lottery unit 19. At this time, the ball detector 92 provided at the entrance of the lottery unit 19 detects the passage of the ball, this detection signal is sent to the control device 50, and the game control unit 50a is used for ball feeding until a predetermined time described later elapses. The rotating body 20 is not rotated. The balls sent to the lottery section 19 enter the notches 47 and 47 of the two lottery rotary bodies 41 and 42 and are received by the ball stopper 48, whereby the balls collide with the notches 47 and 47 and mesh with each other. As described above, the two lottery rotating bodies 41 and 42 are stopped. When the operation stops, the lottery processing unit 50b of the control device 50 obtains a winning lottery result based on the rotation angle information from the encoders 52 and 52. That is, after the lottery rotators 41 and 42 are stopped, no detection pulse is sent from the encoder 52, so that the lottery rotator stop detection unit 50c judges this to detect the stop of the lottery rotators 41 and 42. it can. Since the rotation angles of the rotating shafts 51 and 51 of the two stopped lottery bodies 41 and 42 that have stopped can be recognized based on the detection pulses that have been sent from the encoder 52 so far, 1 is determined based on the recognized rotation angle. The lottery element recognition unit 50d can recognize what the lottery elements 46 and 46 correspond to the notches of the lottery rotators 41 and 42 stopped by a single ball. Then, whether or not the combination of the lottery elements 46 and 46 is a win or not is determined by the hit / decision determining unit 50e. If it is a win, the game control unit 50a controls the gaming machine to a special game state. Since the motor 43 continues to be driven even when the lottery rotators 41 and 42 are stopped, the lottery rotators 41 and 42 cannot be rotated by the ball and cannot rotate, and the lottery rotators 41 and 42 and the rotary shaft 51, Since the cam bodies 64 and 64 connected via 51 do not rotate, the cam follower mounting bodies 65 and 65 connected to the transmission shafts 55 and 55 that continue to rotate by the motor 43 try to rotate. , 66 move out of the power transmission locking portions 80, 80 of FIG. 5 and move to the surface B, and then move to the power cut-off portion 81 (E surface) via the route (1) or route (2). While the cam follower body 74 slides on the surface E of the blocking portion 81 and the cam follower mounting body 65 continues to rotate, the engagement between the cam body 64 and the cam follower body 74 is released, so that the power transmission is completely blocked. Is done.
In the first embodiment, immediately after the lottery rotators 41 and 42 are stopped, the power cut-off operation of the clutch unit 60 and the hit determination process by the lottery processing unit 50b are performed in parallel, and the rotation of the lottery rotators 41 and 42 is stopped. Since the time from power off to power cutoff is shortened, the burden on the motor 43 and the lottery rotators 41 and 42 can be reduced.
When the power transmission is interrupted, the lottery rotators 41 and 42 are in a no-load state, the contact state between the notches 47 and 47 and the ball is released, and the ball moves through the ball escape hole 85 to the ball discharge rod 86. It is collected in a ball collection box outside the figure. At this time, the ball detector 93 of the ball discharge rod 86 detects the ball discharge, and this detection signal is sent to the control device 50, and the game control unit 50a drives the solenoid 72 after receiving this detection signal. If this detection signal is output to the control device 50, it means that the large rotational load of the lottery rotators 41, 42 by the ball has been released, and the load on the motor 43 is small even if power is transmitted. State. Therefore, by detecting the detection signal and setting the power transmission state, the load on the motor 43 and the lottery rotators 41 and 42 when the power transmission state is established can be reliably released, so the motor 43 and the lottery The burden on the rotary members 41 and 42 can be reduced. When the solenoid 72 is driven, the operating shaft 72a protrudes and pushes the cam follower mounting body 65 forward, so that the cam follower main body 74 is fitted to the power transmission locking portion 80 via the path (3) or path (4) in FIG. It gets stuck and enters a power transmission state, and the lottery rotators 41 and 42 rotate again. At this time, if the lottery rotators 41 and 42 rotate once after returning to the power transmission state and the encoder 52 detects the origin of the slit plate 52a, this detection signal is sent to the control device 50. The ball feeding rotator 20 is rotated by a predetermined angle. That is, the time from when the ball detector 92 provided at the entrance of the lottery unit 19 is detected to pass the ball until the encoder 52 detects the origin after returning from the power cut-off state to the power transmission state is defined as a specified time. The ball feeding rotator 20 is not rotated within the specified time. Accordingly, the rotation angle can be accurately detected even after the power is cut off, and the control device 50 can accurately recognize the two lottery elements 46 and 46 corresponding to one sphere.
[0022]
Embodiment 2
In the above description, the fixed ball stopper 48 is used. However, a ball stopper that can move back and forth may be used. That is, a ball stopper with a drive mechanism such as a solenoid (not shown) is attached to the mounting base 13, and when the lottery rotating bodies 41 and 42 are rotating, the ball stopper is projected forward from the mounting base 13 by the solenoid, and lottery is performed. The ball stopper may be moved backward to the back side of the mounting base 13 with a solenoid after the rotation angle information of the lottery rotators 41 and 42 stopped by the processing unit 50 b is input from the encoder 52. In this case, for example, if a rising wall for hooking the ball to the front part of the ball stopper and guiding it to the ball discharge rod 86 is provided, the ball can be led to the back side of the game board 1 and discharged out of the game area. In the case of the second embodiment, the power transmission by the clutch unit 60 may be interrupted as in the first embodiment, but a configuration in which the power is not interrupted is also possible.
[0023]
Embodiment 3
Power transmission and power interruption may be performed using an electromagnetic clutch. In this case, for example, after the rotation angle information of the lottery rotators 41 and 42 stopped by the lottery processing unit 50b is input from the encoder 52, the electromagnetic clutch is put into a power cut-off state, and the lottery processing unit 50b makes a hit determination. A power transmission state may be established by connecting an electromagnetic clutch.
[0024]
According to the first to third embodiments, the denominator of the probability of winning in the winning lottery can be increased, and the time from when the ball is taken into the lottery unit 19 until the winning lottery result is obtained can be shortened. Thus, it is possible to obtain a game component that can process a lottery game as soon as possible and improve game playability and perform a lottery game by hitting a ball.
[0025]
If the number of lottery elements 46 provided in the lottery rotators 41 and 42 is increased, a gaming machine having a hit probability of about 1 / several hundreds can be obtained. The number of lottery elements of the lottery rotator 41 is Za, the number of lottery elements of the lottery rotator 42 is Zb, the rotation speed of the lottery rotator 41 is na, and the rotation speed of the lottery rotator 42 is nb. In this case, if Za / Zb and Zb / Za are not integers and (Za × na) / (Zb × nb) = 1, the number of notches 47 per lottery element is set. However, it is not always necessary to set in this way.
Further, a cam follower may be provided on the cylindrical body constituting the cam body described above, and the inner surface of the cylindrical body constituting the cam follower mounting body may be used as the cam body. That is, the cam body may be connected to one of the rotating body and the driving source, and the cam follower mounting body may be connected to the other of the rotating body and the driving source.
