Description

【０００１】
【発明の属する技術分野】
本発明は、パチンコ遊技機や雀球遊技機など、遊技球を弾発して遊技を行なう弾球遊技機に関するもので、特に、遊技球が流下する遊技部を形成した遊技盤を着脱可能に装着した弾球遊技機に関する。
【０００２】
【従来の技術】
従来の代表的な弾球遊技機であるパチンコ遊技機においては、比較的短期間で遊技盤を交換して、集客力を高めている。この様な、パチンコ遊技機は、一般的には、内枠乃至前面枠と呼ばれる枠体に取付フレームを設け、該取付フレーム内に遊技盤を前方または後方から装填し、枠体に設けた止着具などのロック機構により遊技盤を取付フレーム内に固定する構成を採用している。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記した従来のパチンコ遊技機は、遊技盤を交換する作業に多大の労力と時間を要していた。即ち、取付フレーム内に新たな遊技盤を装填し、この遊技盤をロックする際に、遊技盤を一方の手で押えていなくてはならないし、他方の手でロック機構を操作しなければならないので、不安定な状態で作業しなければならなかった。しかも、ロック機構の操作部は、遊技者側から見えると体裁を損ねるので枠体の裏側に設けてある。したがって、枠体の表側に伸ばした一方の手で遊技盤を押え、枠体の裏側に伸ばした他方の手でロック機構の操作部を操作しなければならず、無理な姿勢での作業を強いられることになり、作業性が極めて劣悪であった。
【０００４】
また、遊技店において新規な遊技盤に交換する場合は、設置された多数の遊技機について短時間で交換しなければならないので、作業を急ぐ余り遊技盤のロックを忘れてしまうことがあった。遊技盤のロックを忘れると、遊技盤が安定しないので、弾発した遊技球が遊技部内に円滑に飛入しなかったり、或は遊技球の流下具合が微妙に変化してしまい、予め予定した入賞率から大きく逸脱するなどの不都合を生じる。
【０００５】
そこで、本発明は、遊技盤の交換作業の作業性に優れ、遊技盤のロックを忘れることなく確実に行え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】
本発明は上記目的を達成するために提案されたもので、請求項１に記載の発明は、打球が流下する遊技部が形成された遊技盤と、該遊技盤を着脱可能に装着する遊技盤装着部を有する枠体と、前記遊技部の前面を被うクリア部材を収納して前記枠体の前面側に対して開閉可能に取り付けられたクリア部材収納枠を備えた弾球遊技機において、
前記枠体の前面側に設けられ、前記クリア部材収納枠を開いて該枠体の前面側から操作可能な操作部を有し、該操作部の操作により遊技盤をロックするロック状態とロックを解除した非ロック状態とに変換可能な遊技盤ロック機構と、

前記遊技盤ロック機構のロック状態では、前記操作部が前記当接回避部に収納され、前記クリア部材収納枠が正常位置まで閉じることを許容するように構成したことを特徴とする弾球遊技機である。
【０００７】

【０００８】
請求項３に記載の発明は、前記遊技盤ロック機構は、前記操作部を上下動させるとロック部材が回動し、該ロック部材に形成したロック部が下降しながら遊技盤装着部内のロック受部に係合するロック状態と、前記ロック部が上昇しながら遊技盤装着部内に突出する長さを減少してロック受部から離脱する非ロック状態と、に変換することを特徴とする請求項１または２に記載の弾球遊技機である。
【０００９】
【発明の実施の態様】
以下、本発明の実施の態様を図面に基づいて説明する。
図１は代表的な弾球遊技機であるパチンコ遊技機１の斜視図、図２はパチンコ遊技機１の正面図、図３は遊技盤２を装着してクリア部材収納枠３を開放した状態のパチンコ遊技機１の斜視図、図４はクリア部材収納枠３および開閉パネル４を開放して遊技盤２を取り外した状態のパチンコ遊技機１の斜視図、図５は遊技盤２を装着する枠体である内枠５の裏面図である。
【００１０】
パチンコ遊技機１は、前後が開放した矩形の外枠（機枠）６と、該外枠６の一側（本実施形態では図中左側）に上下のヒンジ機構７，７により外枠６の前面開口部分に対して開閉可能に軸着した額縁状の内枠５と、該内枠５の一側にヒンジ機構８，８により開閉可能に軸着して内枠５の上半を全幅にわたって被うようにして設けたクリア部材収納枠３と、該クリア部材収納枠３の下方一側にヒンジ機構により開閉可能に軸着して内枠５の下半を全幅にわたって被うようにして設けた開閉パネル４などからなり、枠体としての内枠５の窓部から後方に一体成形した遊技盤装着部９内に遊技盤２を装着してクリア部材収納枠３を閉じると、遊技盤２の表面に形成した遊技部１０がパチンコ遊技機１の前面に臨んで、この遊技部１０を遊技者がクリア部材収納枠３の板ガラス１１を通して見られるように構成されている。また、開閉パネル４の表面に上皿１２を、開閉パネル４の下側の内枠５の前面部分には下皿１３と打球発射装置の発射操作ハンドル１４をそれぞれ設けてある。
【００１１】
内枠５は、合成樹脂製であって、図４に示すように、クリア部材収納枠３の裏側に位置する上横部５ａ、左右縦部５ｂ，５ｃ、及び開閉パネル４の裏側に上半が位置して下半には下皿１３や打球発射ハンドル１４等を設ける下横部５ｄの四周を矩形に成形するとともに、この四周に囲まれた開口部の開口縁から後方に向けて浅い箱状の遊技盤装着部９を一体成形し、遊技盤装着部９の背面には背面部１５を残して開口部１６を開設してある。そして、遊技盤装着部９の背面部１５と側面部との隅角部内には、遊技盤２の背面乃至後端に当接して遊技盤２の後退位置を規制し、遊技盤２の側端縁に当接して遊技盤２の上下左右方向の位置を規制するＬ字形リブ状の位置決め部１７を一体成形する。なお、内枠５は、上横部５ａ、左右縦部５ｂ，５ｃ、及び下横部５ｄの裏面に補強金属板を固定することにより補強されており、左縦部５ｂの裏面に固定した補強金属板にヒンジ機構７を構成する支軸や軸孔を設け、この支軸や軸孔により外枠６に対して軸着されている。
【００１２】
上記した構成からなる遊技盤装着部９には、遊技盤２を仮止めするための仮止め機構２０の主要部を構成する永久磁石２１を設ける。本実施形態では、図６に示すように、遊技盤装着部９の背面部１５の一側（本実施態様では内枠５の自由端側）に形成した凹部内に永久磁石２１を埋没させた状態で固定し、該永久磁石２１の表面（前面）を背面部１５の前面とほぼ面一にする。
なお、本願における仮止めとは、本来の稼働状態に耐え得る取付強度までには至らなくても、自然状態に放置してもその状態を維持し得る強度で止めた状態を言う。
【００１３】
また、本実施形態では、後述するように、遊技盤２の一側を遊技盤装着部９に軸着するので、軸着側とは反対側の自由端側にのみ永久磁石２１を配設したが、さらに個数を増やして左右中央や軸着端近くなどに配設してもよい。要するに、遊技盤２を永久磁石２１の吸着力を利用して遊技盤装着部９に仮止めすることができる位置に配置してあればよい。したがって、本実施態様では永久磁石２１を遊技盤装着部９に設けて、この永久磁石２１に吸着される被吸着部２２を遊技盤２に設けたが、逆に、遊技盤２に永久磁石２１を、遊技盤装着部９に被吸着部２２を設けてもよい。
【００１４】
また、遊技盤装着部９内の一側、本実施態様では遊技盤装着部９を構成している上面部の一側と下面部の一側に、軸受部として軸孔２３を上下対向する位置に開設する。そして、軸孔２３とは反対側（他側）に遊技盤ロック機構２４の一部を構成するロック部材２５を設けるとともに、遊技盤ロック機構２４の操作部２６を設ける。
【００１５】
図７に示す遊技盤ロック機構２４は、内枠５の自由端側の右縦材５ｃの前面に、前方に突出する操作部２６を有する操作部本体２７を上下動可能な状態で設け、該操作部本体２７の下端から延設した連結部２８の下端に遊技盤ロック部材２５の一端を回動可能な状態で軸着し、該ロック部材２５の途中に形成したボス部を内枠５側に回動可能な状態で軸着し、ロック部材２５の他端に形成した爪状のロック部３０を、遊技盤装着部９の側面部に開設した開口部から遊技盤装着部９内に臨ませてなる。したがって、作業者が操作するための操作部２６と遊技盤２のロック受部３３に係止して遊技盤２をロックするロック部３０との間に介在する操作部本体２７、軸３１、ロック部材２５などが操作部２６の動きをロック部３０に伝達する伝達部材として機能する。
【００１６】
この様な構成からなる遊技盤ロック機構２４において、内枠５の前面側から操作部２６を上下動させると、例えば図７（ａ）に示すように、ロック部材２５がほぼ水平に位置してロック部３０が遊技盤装着部９内に大きく突出したロック状態から操作部２６を下方に移動すると、連結部２８に押圧されてロック部材２５の一端が下降するので、ロック部材２５が軸３１を中心にして反時計方向に回動する。したがって、遊技盤装着部９内に突出したロック部３０の突出長さが短くなって非ロック状態に変換する。一方、この非ロック状態から操作部２６を上方に移動すると、ロック部材２５の一端が連結部２８によって引き上げられるので、ロック部材２５が軸３１を中心にして時計方向に回動する。したがって、ロック部３０が下降しながら遊技盤装着部９内に大きく突出してロック状態に変換する。
【００１７】
この様にして、ロック部３０が遊技盤装着部９内に大きく突出すると、ロック部３０が突出する位置に遊技盤２の側面に設けたロック受部３３が位置しているので、突出したロック部３０が遊技盤２のロック受部３３に係合し、該遊技盤２をロックすることができる（ロック状態）。なお、図７（ｂ）に示すロック受部３３は、Ｖ字状の溝として形成されており、尚且つロック部３０が移動しながら突出長さを増大する方向に合わせて内法を次第に減少させて形成してある。したがって、ロック部３０が十分な突出長さまで突出すると、このロック部３０は、前後の面或は稜がＶ字状溝の前後の内縁乃至内面に同時に係合し、これにより遊技盤２の前後位置を所定位置に合わせた状態でロックするとともに、前後動のガタを防止する。
【００１８】
なお、上記したロック状態で、操作部２６を下方に移動すると、ロック部材２５が軸３１を中心にして反時計方向に回動してロック部３０が上昇しながら突出長さを減少し、十分に回動するとロック部３０がロック受部３３から離脱し、これによりロックが解除される（非ロック状態）。
【００１９】
遊技盤ロック機構２４は、内枠５の前面から操作部２６を操作することにより遊技盤装着部９内に遊技盤２をロックしたり解除したりできればどのような構成でもよい。例えば、図８に示す遊技盤ロック機構２４は、ロック部材２５のロック部３０の先端に押圧突起３４を形成し、ロック受部３３には、遊技盤２を後方の遊技盤装着部９の背面側に押圧する方向に傾斜した傾斜受部３５を形成したものである。この遊技盤ロック機構２４では、操作部２６を操作することによりロック部材２５を回動してロック部３０をロック受部３３に十分に係合させてロックすると、係合深さが増えるにしたがって押圧突起３４が傾斜受部３５を次第に強く圧接する。したがって、ロック部３０を十分に深く係合してロックすると、押圧突起３４が傾斜受部３５を内枠５後方に押圧し、これにより遊技盤２が十分に後退して所定位置に強制的に移動させられ、尚且つ前後方向のガタがなくなる。
【００２０】
また、図９に示す遊技盤ロック機構２４は、ロック部材２５のロック部３０を二股に形成し、ロック受部３３は二股ロック部３０が凹部にそれぞれ入り込んで両ロック部３０間に嵌合する係合片３６を備える。この遊技盤ロック機構２４では、操作部２６を操作することによりロック部材２５を回動すると、二股のロック部３０が係合片３６を挟んだ状態でそれぞれ凹部内に入り込む。そして、ロック受部３３が十分に回動すると、二股のロック部３０が係合片３６を挟み付けてロックするとともに、遊技盤２の前後位置を規制する。したがって、ロック部３０を十分に深く係合してロックすると、これにより遊技盤２が所定位置に強制的に移動させられ、この状態でロックされる。
【００２１】
この様に、遊技盤２をロックする遊技盤ロック機構２４や仮止め機構２０を備えた内枠５は、施錠装置の一部を構成するフックによって外枠６の他側の係止部材に自由端側が施錠される。
【００２２】
また、クリア部材収納枠３は、遊技盤ロック機構２４がロック状態に変換していれば、手で内枠５側に軽く押し付けるだけで所定の位置（支障なく稼働できる正常位置）まで閉じて、施錠装置を構成する他のフック３７によって自由端側が内枠５の他側に施錠される。一方、遊技盤ロック機構２４が非ロック状態に変換したままであると、手で押し付けてもクリア部材収納枠閉止動作規制機構３８の作用により所定位置まで閉じることが阻止され、作業者に遊技盤ロック機構２４が非ロック状態であることを知らしめる構成と成っている。そして、クリア部材収納枠３を所定位置まで閉じると施錠装置のフック３７がクリア部材収納枠３を施錠し、所定位置まで閉じられない場合には施錠されない。この様な内枠５並びにクリア部材収納枠３の施錠は、内枠５の上部一側に設けたシリンダ錠３９の鍵穴に差し込んだ鍵を一方に回動すると内枠５が、他方に回動するとクリア部材収納枠３が解錠する。
【００２３】
次に、枠体である内枠５とクリア部材収納枠３の相対向する位置、即ち内枠５の前面側とクリア部材収納枠３の裏面側に設けられ、クリア部材収納枠３の閉止動作を、遊技盤ロック機構２４の状態に関連して規制するクリア部材収納枠閉止動作規制機構３８について説明する。
【００２４】
クリア部材収納枠３は、合成樹脂製枠体の中央開口部にクリア部材として板ガラス１１や透明プラスチック板を装着したもので、裏面側には、図１０に示すように、金属製補強材６０を設け、この補強材６０の一部に施錠装置のフック３７が貫通する貫通孔６１を開設して該貫通孔６１の縁をフック３７の係合部とし、クリア部材収納枠３が正常位置まで回動して内枠５に対して正常に閉じると、フック３７が補強材６０の係合部に係合する様に、フック３７の突出長さ及び係合爪部３７′の位置を設定するとともに、係合部の前後位置を設定してある。
【００２５】
また、本実施形態で可動当接部６２として機能する前記操作部２６が非ロック状態で停止する位置に対応する補強材６０の一部を固定当接部６３とし、操作部２６がロック状態で停止する位置に対応する補強材６０の一部に操作部２６の突出先端部分を収納可能な凹部状の当接回避部６４を形成する。補強材６０の固定当接部６３として機能する部分は、図１０に示すように、クリア部材収納枠３が正常位置に閉じる手前で非ロック状態における操作部２６（可動当接部６２）に当接する位置に配置してある。一方、当接回避部６４は、図１０に示すように、クリア部材収納枠３が正常位置に閉じた状態でロック状態における操作部２６に当接しない十分な深さで凹部状に形成してある。
【００２６】
したがって、遊技盤ロック機構２４の操作部２６が非ロック状態のままで、大きく開いているクリア部材収納枠３を手で内枠５側に押圧して閉止動作を開始すると、図１０（ｂ）に示すように、クリア部材収納枠３が内枠５の正常位置に到達する手前でクリア部材収納枠３側の固定当接部６３が、可動当接部６２としての操作部２６の突出先端部分に当接し、この固定当接部６３と可動当接部６２との当接によりクリア部材収納枠３の閉止動作がこの時点で阻止される。このため、クリア部材収納枠３の前端部分は内枠５の前面よりも突出したままであり、クリア部材収納枠３を手で押圧して閉じようとしている作業者は、クリア部材収納枠３が所定位置まで閉じないこと、即ち遊技盤ロック機構２４のロックを忘れてクリア部材収納枠３を閉じようとしたことを認識することができる。また、固定当接部６３と可動当接部６２との当接によりクリア部材収納枠３が正常位置まで閉じないと、フック３７が補強板６０の貫通孔６１内に十分貫通しないので、自動的に施錠することもない。
【００２７】
ロック忘れに気付いた作業者がクリア部材収納枠３を再び開いてから操作部２６を操作（本実施形態では操作部２６を上方にスライド）することにより遊技盤ロック機構２４をロック状態に変換すると、遊技盤２がロックされる。そして、再度クリア部材収納枠３を手で押圧して閉止動作を行うと、今度は図１０（ａ）に示すように、操作部２６（可動当接部６２）が固定当接部６３に対向する位置から上方に移動することで当接位置から外れており、また、この状態における操作部２６に対向する位置には凹部状の当接回避部６４が形成されているので、クリア部材収納枠３は内枠５に対して十分に深く正常位置まで閉じることが許容される。この様にして、クリア部材収納枠３が正常位置まで回動して閉じると、クリア部材収納枠３と内枠５の前面同士がほぼ面一になり、また、フック３７が補強板６０の貫通孔６１内に十分深く貫通して、スプリングの付勢によりフック３７の係合爪３７′が貫通孔６１の縁に係合して施錠する。この状態になると、遊技盤ロック機構２４の操作部２６が当接回避部６４内に収納されて移動が拘束されるので、打球の発射動作などに伴う振動を受けても遊技盤ロック機構２４はロック解除してしまうことはない。したがって、クリア部材収納枠３を閉じている限り、遊技盤２のロック状態は確実に維持される。
【００２８】
この様に、遊技盤ロック機構２４のロックを忘れるとクリア部材収納枠３が所定の正常位置まで閉じることができないので、クリア部材収納枠３を手で閉じればすぐにロック忘れに気付く構成であるが、クリア部材収納枠３を閉じる前にロック状態を視覚を通して確認できるように、遊技盤ロック状態表示手段７０を設けてある。
【００２９】
図面に示す遊技盤ロック状態表示手段７０は、操作部２６をスライド可能な状態で取り付ける内枠５の前面走行部分であって操作部２６の非ロック時に表れ、ロック時に操作部２６に被い隠される部分に非ロック状態である旨の表示「開放」を記してある。したがって、操作部２６を操作してロック状態に変換すれば、図１１（ｂ）に示すように、「開放」の表示は作業者から見えないが、ロックを忘れて非ロック状態のままであると、図１１（ａ）に示すように、「開放」が表示されたままとなり、作業者に非ロック状態（開放）である旨を可視表示する。このため、作業者は、クリア部材収納枠３を閉じる際に上記「開放」表示を確認するだけで遊技盤２のロックを確認することができる。
【００３０】
なお、遊技盤ロック状態表示手段７０は、遊技盤ロック機構２４のロック状態と、非ロック状態とで表示が変化し、作業者が遊技盤２のロック状態を視覚を通して確認することができる構成であればどのような構成でもよい。例えば、ロック状態で操作部により被い隠され、非ロック状態で操作部が外れて表れる部分を赤く着色してもよい。
【００３１】
次に、上記した内枠５の遊技盤装着部９に装着する遊技盤２について説明する。
遊技盤２は、図１２（ａ）に示すように、前面に、ガイドレールなどの区画部材により区画して遊技部１０を形成し、該遊技部１０内に無数の障害釘４０や入賞装置４１などを設けたものである。本実施形態における遊技盤２は、合成樹脂により全体として中空略矩形板状体に成型したもので、上下左右四周の縁面部４２に囲まれた前面部４３に略円形の遊技部１０を凹部状に形成し、前面部４３の円形内縁と遊技面４４の外縁との間の曲面が区画部材として機能し、この区画部材の一部の内側に内側ガイドレール４５を止着して球案内流路４６を形成し、内側ガイドレール４５及び区画部材により囲まれた遊技部１０内の最下位置にアウト口４７を開設し、該遊技部１０内には障害釘４０…を植設し、センター役物４８や可変表示装置や入賞装置４１を設けたりする。
【００３２】
なお、本実施形態では、アウト口４７の裏側の下部にアウト球流下路４９を形成し、遊技盤２の厚み内でアウト球を処理できるように構成してある。また、障害釘４０を植設する遊技面４４の裏側には、障害釘４０の根本を支持するための凸部５０を一体成型してある。したがって、合成樹脂製遊技面４４に金属製障害釘４０を植設（インサート成型でも、別個打ち込んでもよい。）しても、該障害釘４０を強固に支持することができ、釘調整の際に衝撃が加えられても損傷したりすることはない。
【００３３】
また、本実施形態における遊技盤２には、遊技盤装着部９に設けた軸受部（軸孔２３）に対応する一側の同一中心線上に回動支持軸５１を設け、他側には遊技盤装着部９に保持可能な仮止め機構２０の一部を構成する被吸着部２２を設けるとともに、遊技盤ロック機構２４の一部を構成するロック受部３３を設ける。
【００３４】
回動支持軸５１は、図１４に示すように、操作部５２となる部分を一端に形成した略Ｌ字状の軸であり、遊技盤２の前面部４３に開設した長孔５３から操作部５２が遊技盤２前面に臨み、上縁面と下縁面に開設した穴から突出する状態で取り付けられている。そして、軸部と操作部５２との間の屈曲部に接続したスプリング５５の弾性力により、軸部が上縁面（下縁面）の穴から突出する方向に付勢されている。したがって、操作部５２を操作しない自然状態では、スプリング５５の付勢により軸部が穴から大きく突出しており、スプリング５５の付勢に抗して操作部５２を操作して回動支持軸５１を移動すると、穴から突出する長さが減少する。したがって、この突出長さを縮小した状態で遊技盤２の一側を遊技盤装着部９内に差入れることができる。そして、操作部５２から手を離すと、スプリング５５の付勢により回動支持軸５１が移動し、突出長さが増大し、この伸長した軸部先端が遊技盤装着部９の軸受部内に嵌合する。
【００３５】
遊技盤２に設ける仮止め機構２０の被吸着部２２は、図６に示すように、遊技盤装着部９に設けた仮止め機構２０の永久磁石２１に対応する位置に配設され、永久磁石２１の磁力によって吸着される部材であり、本実施態様では、鉄板を略凸状に屈曲成形し、フランジ部５６に開設した取付孔内にビスを通し、該ビスを、遊技盤２の裏面に突設したボス５７の取付孔内にねじ込むことにより止着されている。なお、被吸着部２２の後端面が永久磁石２１に吸着されるので、この後端面は、遊技盤２の板厚に応じて、遊技盤２仮想背面に合わせてある。
【００３６】
次に、上記した構成からなる遊技盤２を内枠５の遊技盤装着部９に装着する遊技盤取付手順について説明する。なお、説明の都合上、それまで装着されていた遊技盤２は既に取り外してあるものとする。
【００３７】
遊技盤２を取り外したパチンコ遊技機１は、図４に示すように、クリア部材収納枠３及び開閉パネル４が大きく開放されており、また、遊技盤ロック機構２４の操作部２６を下降して非ロック状態に変換してあるので、遊技盤ロック状態表示手段７０の「開放」が表示されている。この状態で新たに装着する遊技盤２を、遊技部１０を手前に向けて持ち上げ、この遊技盤２の回動支持軸５１側の一側を遊技盤装着部９内に装填する。この時、回動支持軸５１の上下の操作部５２を操作することにより、上下に突出している回動支持軸５１の突出長さを短くしてから差し込む。
【００３８】
なお、下側の回動支持軸５１側を上側よりも先に差し込めば、この下側の回動支持軸５１を短くしなくても差し込むことができる。したがって、下側の回動支持軸５１は固定したまま、即ち突出長さを調整できないようにしてあってもよい。固定したままであれば、構造が簡単になり製造工程も簡素になりコストダウンに寄与する。また、遊技盤装着部９に回動支持軸５１を設け、遊技盤２には、この回動支持軸５１が嵌合する軸孔２３を設けてもよい。この様に構成すると、遊技盤２に突出する部分が少なくなるので、工場からの搬送を含めて取り扱いが容易になる。
【００３９】
この様にして、遊技盤２の回動支持軸５１側の一側を遊技盤装着部９内に差し込んだならば、次に、位置を合わせて操作部５２から手を離す。回動支持軸５１はスプリング５５により付勢されているので、操作部５２が放されると、上下の軸部が伸長して遊技盤装着部９の軸受部（軸孔２３）内に嵌合する。したがって、遊技盤２は、一側の上下に設けられている回動支持軸５１により遊技盤装着部９に対して回動可能な状態で軸着される。
【００４０】
そして、この状態で遊技盤２の自由端側を手で遊技盤装着部９側に押圧すると、遊技盤２が回動支持軸５１を中心にして水平方向に回動する。この様に、遊技盤２の一側を回動支持軸５１及び軸孔２３により軸着すると、遊技盤２の裏側にセンター役物４８や可変表示器や大型入賞装置などの部材が突出したり、或は遊技盤装着部９の開口部の開口縁との隙間が少ない位置に部品が突出していても、これら突出した部材が遊技盤装着部９の開口部１６内に入るように位置合わせ作業を行わなくても、回動支持軸５１を中心にして遊技盤２を回動させるだけで、上記突出部分が開口部１６内に自ずと挿通される。したがって、この点においても遊技盤２の装着作業の容易化に寄与する。
【００４１】
なお、遊技盤装着部９の開口部１６と、遊技盤２の裏側に突出する部材との間のクリアランスを設計上、従来よりも小さく設定することができると、遊技盤２の裏側に突出する部材を従来よりも広い範囲に配置することができるので、設計の自由度が増大するとともに、遊技部１０内の部品の配置を工夫することにより遊技の興趣を高めることができる。また、遊技盤２の裏側には配線コードが出ており、この配線コードを遊技盤装着部９の開口部１６内に通すことが必要な場合があるが、遊技盤２の一側が回動支持軸５１により軸着されていると、配線コードを上記開口部１６に通す作業も両手で効率良く、安心して行うことができる。
【００４２】
遊技盤２を十分に回動すると、遊技盤２の縁面部４２が位置決め部１７に当接して遊技盤２の上下及び左右の位置が規制されて遊技盤２が所定位置に案内される。また、遊技盤２を十分に回動して押圧すると、縁面部４２の後端縁が位置決め部１７に当接して後退位置も規制される。さらにまた、遊技盤２が位置決め部１７の作用により所定の位置に案内されると、遊技盤２の裏側の設けてある被吸着部２２が遊技盤装着部９側の永久磁石２１に当接乃至近接するので、永久磁石２１の吸着力により被吸着部２２が吸引される。したがって、遊技盤２は、作業者が手を離しても、永久磁石２１の吸着力によって遊技盤装着部９内に仮止めされ、その状態を保持する。このため、作業者は、遊技盤２を遊技盤装着部９内に取り敢えず押し込めば、安心して手を離すことができ、必要に応じて他の作業を行なうこともできる。
【００４３】
上記した仮止め操作によって遊技盤２を仮止めしたならば、次に、内枠５の前面に設けてある遊技盤ロック機構２４の操作部２６を操作する。この操作部２６を操作すると、前記したように、遊技盤ロック機構２４のロック部材２５が軸３１を中心にして回動し、ロック部３０が遊技盤２のロック受部３３に係合し、当該遊技盤２を所定の位置でロックすることができる。また、操作部２６を操作して遊技盤ロック機構２４をロック状態に変換すると、「開放」の表示が操作部本体２７によって被い隠される。
【００４４】
そして、遊技盤２をロックしたならば、遊技盤２に取り付けられている部材の配線コードを所定のコネクタに接続するなどの残された作業を行う。この作業を行う場合、内枠５の裏側で作業することになるが、遊技盤２は既に内枠５側にロックされているので、遊技盤２を片手で押えるなどの不自然な姿勢をとる必要もなく、内枠５の裏側で自然な姿勢で両手が作業することができる。
【００４５】
この様に、本実施形態では、遊技盤２の一側に回動支持軸５１を設け、また、遊技盤２を仮止めする仮止め機構２０を備えており、しかも遊技盤ロック機構２４の操作部２６を内枠５の前面に設けたので、遊技盤２を内枠５の遊技盤装着部９に装着する際に、パチンコ遊技機１の前面側から自然な姿勢を崩すことなく作業を行なうことができる。したがって、作業性に優れている。また、遊技盤装着部９内に遊技盤２を押し入れるだけで、当該遊技盤２は仮止めされるので、遊技盤２の重量が増大していても、作業を容易に行うことができるばかりでなく、作業の安全性を高めることができる。
【００４６】
そして、内枠５の遊技盤装着部９に遊技盤２を装着する作業が終了してクリア部材収納枠３を閉じると、遊技盤２の遊技部１０がクリア部材収納枠３の板ガラス１１を通して見える状態となる。また、遊技盤ロック機構２４の操作部２６は、内枠５の前面の一側に配置されているが、クリア部材収納枠３を閉じると、操作部２６はこのクリア部材収納枠３に覆い隠される。したがって、操作部２６は遊技者側から見えることがなく、内枠５の前面に操作部２６を設けても、パチンコ遊技機１の体裁を損ねることがない。また、遊技盤ロック機構２４の操作部２６がロックした状態でない場合、即ちロックを解除した状態あるいはロックが不完全な状態でクリア部材収納枠３を閉じると、前方に突出した操作部２６がクリア部材収納枠３に当って正常位置まで閉まらないので、ロック忘れや不完全ロックを防止することができる。
【００４７】
なお、上記した実施形態では遊技盤ロック機構２４の操作部２６をスライド式とし、この操作部２６を内枠５の前面に突出した状態で設けて可動当接部６２としたが、この可動当接部６２は、遊技盤ロック機構２４のロック状態と非ロック状態とで位置や突出長さなどが状態変換に伴って変化して、ロック状態で固定当接部６３に当接するが、非ロック状態では固定当接部６３の当接位置から外れるものであればどのような構成でもよい。例えば、内枠５の前面にレバー式操作部（図示せず）を軸着し、このレバーを引き起こすと、レバーの動きをリンク機構等の伝達部材によりロック部３０に伝達して非ロック状態とし、レバーを倒す（内枠５の前面に対してほぼ平行にする）とロック状態に変換する様にして、非ロック状態で起立したレバーがクリア部材収納枠３の固定当接部６３に当接することによりクリア部材収納枠３の閉止動作を規制するように構成してもよいし、凸部を有するダイヤル式操作部（図示せず）を設け、状態変換に伴って位置が変化する凸部を可動当接部６２としてもよい。
【００４８】
また、可動当接部６２は操作部２６自体に限定されるものではなく、遊技盤ロック機構２４のロック状態と非ロック状態との状態変換に伴って位置や突出長さなどが変化し、非ロック状態のときに固定当接部６３に当接してクリア部材収納枠３の閉止動作を規制できれば、操作部２６の動きに連動して位置や突出長さが変化する部材を別途設けてもよい。
【００４９】
一方、可動当接部６２に当接する固定当接部６３は、クリア部材収納枠３の裏側に設けられて、非ロック状態の時に限って可動当接部６２に当接してクリア部材収納枠３の閉止動作を正常位置の手前で止めることができれば、クリア部材収納枠３の補強材６０の一部に限らずどのような構成でもよい。例えば、クリア部材収納枠３の裏側に、補強材６０とは別個に突設してもよいし、クリア部材収納枠３と一体成型してもよい。
【００５０】
また、仮止め機構２０は、前記実施形態に限るものではなく、遊技盤２と遊技盤装着部９との相対向する位置に配設され、遊技盤２から遊技盤装着部９への押圧力を受けると逆方向（即ち、遊技盤２が外れる方向）への移動に抵抗力を発生して遊技盤２を保持可能であればどのような構成でもよい。例えば、遊技盤２の裏面側、例えば遊技盤２と一体成型した被吸着部２２の背面に一方の面ファスナーを添設し、遊技盤装着部の内面に他方の面ファスナーを添設し、遊技盤２を押圧すると該遊技盤２の面ファスナーが遊技盤装着部９側の面ファスナーに止着して遊技盤２を仮止めできるように構成してもよい。面ファスナーは、例えば、ベース面に小さなフープを無数に形成したものと、ベース面に小さなフックを無数に突設したものとからなり、フックとフープとを押圧すると両者が係合することにより剥離抵抗を生じる構成の部材や、フックとフープの代わりに多数の小突起と該小突起に係合可能な段部や、小突起同士を係合するものなどである。この様に、仮止め機構に面ファスナーを用いると、磁力の影響を受けることがないので、鉄製遊技球が磁化するおそれもない。
【００５１】
また、遊技盤２の裏面に弾性係止爪を設け、遊技盤装着部９には弾性係止爪が係止可能な受段部を設け、この受段部と弾性係止爪との係合により遊技盤２を仮止めできるように構成してもよい。
【００５２】
また、これまで説明した実施態様は、パチンコ遊技機１について説明したが、本発明は、パチンコ遊技機１に限定されるものではなく、遊技部１０を形成した遊技盤２を備えた弾球遊技機であればどのような遊技形態の遊技機であってもよい。例えば、雀球遊技機、スマートボール遊技機などでもよい。また、遊技盤２を装着する枠体は、合成樹脂製に限定されるものではなく、木製であってもよい。
【００５３】
【発明の効果】
以上説明したように本発明によれば、枠体の遊技盤装着部に遊技盤を装着する際に、遊技盤ロック機構の操作部が枠体の前面に配設されているので、前面側からロック操作することができる。そして、遊技盤のロックを忘れてクリア部材収納枠を閉じようとすると、このクリア部材収納枠がクリア部材閉止動作規制機構により正常位置まで閉じないようになっており、このクリア部材閉止動作規制機構は、遊技盤ロック機構の操作部とクリア部材収納枠の裏面側に設けた固定当接部との当接によりクリア部材収納枠の閉止動作を規制するので、ロック忘れを簡単な構造で確実に防止することができる。したがって、遊技盤の交換作業を能率良く行うことができ、短時間で多数の弾球遊技機の作業を終了することができるばかりでなく、各弾球遊技機の遊技盤のロック忘れを確実に防止することができる。そして、遊技盤のロック忘れを確実に防止できると、遊技盤と他の部品との接続も確実に行われるし、遊技盤もがたつくことなく安定する。
【００５４】
また、遊技盤ロック状態表示手段により遊技盤のロック状態、非ロック状態を視覚を通して確認することができる。したがって、クリア部材収納枠を閉じるまでもなく遊技盤のロックを確認することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a ball ball game machine that plays a game ball by playing a game ball, such as a pachinko game machine or a sparrow ball game machine, and in particular, a game board that forms a game part where the game ball flows down is detachably mounted. It relates to a ball game machine.
[0002]
[Prior art]
In pachinko gaming machines, which are typical conventional ball game machines, the ability to attract customers is increased by exchanging game boards in a relatively short period of time. Such a pachinko gaming machine is generally provided with a mounting frame on a frame called an inner frame or a front frame, and a game board is loaded into the mounting frame from the front or the rear, and a stop provided on the frame. A configuration is adopted in which the game board is fixed in the mounting frame by a lock mechanism such as a dressing device.
[0003]
[Problems to be solved by the invention]
However, the conventional pachinko gaming machine described above requires a great deal of labor and time for the work of replacing the game board. That is, when a new game board is loaded in the mounting frame and the game board is locked, the game board must be pressed with one hand and the lock mechanism must be operated with the other hand. So I had to work in an unstable state. Moreover, the operation part of the lock mechanism is provided on the back side of the frame body because it looks bad when viewed from the player side. Therefore, it is necessary to press the game board with one hand extended to the front side of the frame body, and to operate the operation part of the lock mechanism with the other hand extended to the back side of the frame body, which makes the work in an unreasonable posture strong. As a result, workability was extremely poor.
[0004]
In addition, when a game board is replaced with a new game board, a large number of installed gaming machines must be exchanged in a short time, so that the game board may be forgotten to be locked too much in a hurry. If you forget to lock the game board, the game board will not be stable, so it will not be able to jump smoothly into the game department, or the flow of the game ball will change slightly. This causes inconveniences such as a significant departure from the winning rate.
[0005]

It is a reverse view of the inner frame 5 which is a frame.
[0010]
The pachinko gaming machine 1 includes a rectangular outer frame (machine frame) 6 that is open at the front and rear, and a hinge mechanism 7 and 7 on one side of the outer frame 6 (left side in the drawing in the present embodiment). A frame-like inner frame 5 that is pivotably attached to the front opening portion, and a hinge mechanism 8, 8 that is pivotally attached to one side of the inner frame 5 so that the upper half of the inner frame 5 extends over the entire width. The clear member storage frame 3 provided to be covered, and provided so that the lower half of the clear member storage frame 3 is pivotally attached to the lower side by a hinge mechanism so as to cover the lower half of the inner frame 5 over the entire width. When the game board 2 is mounted in the game board mounting portion 9 integrally formed rearward from the window portion of the inner frame 5 as a frame body and the clear member storage frame 3 is closed, the game board 2 The game part 10 formed on the surface of the game machine faces the front surface of the pachinko gaming machine 1 and the player clicks on the game part 10. It is configured to be viewed through member accommodating frame 3 of the glass sheet 11. Further, an upper plate 12 is provided on the surface of the open / close panel 4, and a lower plate 13 and a firing operation handle 14 of the hitting ball launching device are provided on the front portion of the inner frame 5 on the lower side of the open / close panel 4.
[0011]
The inner frame 5 is made of synthetic resin, and as shown in FIG. 4, the upper horizontal portion 5 a located on the back side of the clear member storage frame 3, the left and right vertical portions 5 b and 5 c, and the upper half on the back side of the opening / closing panel 4. In the lower half, the lower half 5d provided with the lower plate 13, the hitting ball launching handle 14 and the like is formed into a rectangular shape on the four sides, and a shallow box from the opening edge of the opening surrounded by the four sides to the rear. A game board mounting portion 9 is integrally formed, and an opening 16 is formed on the back surface of the game board mounting portion 9 leaving a back surface portion 15. And in the corner part of the back part 15 and the side part of the game board mounting part 9, it contacts the back side or the rear end of the game board 2 to regulate the retreat position of the game board 2, and the side edge of the game board 2 An L-shaped rib-shaped positioning portion 17 that contacts the edge and regulates the position of the game board 2 in the vertical and horizontal directions is integrally formed. The inner frame 5 is reinforced by fixing a reinforcing metal plate to the back surfaces of the upper horizontal portion 5a, the left and right vertical portions 5b and 5c, and the lower horizontal portion 5d, and the reinforcement fixed to the back surface of the left vertical portion 5b. The metal plate is provided with a support shaft and a shaft hole constituting the hinge mechanism 7 and is attached to the outer frame 6 by this support shaft and shaft hole.
[0012]
The game board mounting portion 9 having the above-described configuration is provided with a permanent magnet 21 that constitutes a main part of the temporary fixing mechanism 20 for temporarily fixing the game board 2. In the present embodiment, as shown in FIG. 6, the permanent magnet 21 is buried in a recess formed on one side of the back surface portion 15 of the game board mounting portion 9 (in this embodiment, the free end side of the inner frame 5). The surface (front surface) of the permanent magnet 21 is substantially flush with the front surface of the back surface portion 15.
In addition, the temporary stop in this application means the state stopped by the intensity | strength which can maintain the state, even if it does not reach the attachment intensity | strength which can endure an original operation state, or it is left in a natural state.
[0013]
In the present embodiment, as will be described later, since one side of the game board 2 is pivotally attached to the game board mounting portion 9, the permanent magnet 21 is disposed only on the free end side opposite to the axis attachment side. However, the number may be further increased and disposed in the center of the left and right or near the shaft end. In short, the game board 2 may be arranged at a position where it can be temporarily fixed to the game board mounting portion 9 by using the attractive force of the permanent magnet 21. Therefore, in this embodiment, the permanent magnet 21 is provided in the game board mounting part 9 and the attracted part 22 to be attracted to the permanent magnet 21 is provided in the game board 2. Alternatively, the attracted portion 22 may be provided in the game board mounting portion 9.
[0014]
In addition, in the present embodiment, a position where the shaft hole 23 is vertically opposed as a bearing portion on one side of the upper surface portion and one side of the lower surface portion constituting the game board mounting portion 9 in this embodiment. To open. A lock member 25 constituting a part of the game board lock mechanism 24 is provided on the opposite side (the other side) to the shaft hole 23, and an operation unit 26 of the game board lock mechanism 24 is provided.
[0015]
The game board locking mechanism 24 shown in FIG. 7 is provided on the front surface of the right vertical member 5c on the free end side of the inner frame 5 with an operation unit body 27 having an operation unit 26 protruding forward in a vertically movable state. One end of the game board lock member 25 is pivotally attached to the lower end of the connecting portion 28 extending from the lower end of the operation portion main body 27 so that the boss portion formed in the middle of the lock member 25 is on the inner frame 5 side. The claw-like lock portion 30 formed on the other end of the lock member 25 is pivotally mounted on the other end of the lock member 25 so as to face the inside of the game board mounting portion 9 from the opening formed in the side surface portion of the game board mounting portion 9. I will do it. Therefore, the operation unit main body 27, the shaft 31, and the lock that are interposed between the operation unit 26 for the operator to operate and the lock unit 30 that locks the game board 2 by being locked to the lock receiving unit 33 of the game board 2 The member 25 or the like functions as a transmission member that transmits the movement of the operation unit 26 to the lock unit 30.
[0016]
In the game board locking mechanism 24 having such a configuration, when the operation unit 26 is moved up and down from the front side of the inner frame 5, for example, as shown in FIG. When the operation unit 26 is moved downward from the locked state in which the lock unit 30 protrudes greatly into the game board mounting unit 9, one end of the lock member 25 is lowered by being pressed by the connecting unit 28, so that the lock member 25 moves the shaft 31. It rotates counterclockwise around the center. Therefore, the protrusion length of the lock portion 30 protruding into the game board mounting portion 9 is shortened and converted to the unlocked state. On the other hand, when the operation part 26 is moved upward from this non-locked state, one end of the lock member 25 is pulled up by the connecting part 28, so that the lock member 25 rotates clockwise about the shaft 31. Therefore, the lock part 30 largely protrudes into the game board mounting part 9 while being lowered and is converted into a locked state.
[0017]
In this way, when the lock part 30 protrudes greatly into the game board mounting part 9, the lock receiving part 33 provided on the side surface of the game board 2 is located at the position where the lock part 30 protrudes. The part 30 engages with the lock receiving part 33 of the game board 2, and the game board 2 can be locked (locked state). The lock receiving portion 33 shown in FIG. 7B is formed as a V-shaped groove, and the inner method is gradually reduced in accordance with the direction in which the lock portion 30 moves and the protruding length increases. Are formed. Therefore, when the lock portion 30 protrudes to a sufficient protruding length, the front and rear surfaces or ridges are simultaneously engaged with the front and rear inner edges or the inner surface of the V-shaped groove, thereby the front and rear of the game board 2. While locking in a state where the position is adjusted to a predetermined position, backlash of back and forth movement is prevented.
[0018]
In the above-mentioned locked state, the operation unit 26 isunderWhen the lock member 25 is moved in the opposite direction, the lock member 25 is rotated counterclockwise about the shaft 31 to reduce the protruding length while the lock portion 30 is raised. The lock is released (unlocked state).
[0019]
The game board lock mechanism 24 may have any configuration as long as the game board 2 can be locked or released in the game board mounting part 9 by operating the operation part 26 from the front surface of the inner frame 5. For example, the game board locking mechanism 24 shown in FIG. 8 has a pressing protrusion 34 formed at the tip of the lock part 30 of the lock member 25, and the lock receiving part 33 is connected to the back of the game board mounting part 9 on the rear side. An inclined receiving portion 35 that is inclined in the direction of pressing toward the side is formed. In this game board lock mechanism 24, when the lock member 25 is rotated by operating the operation portion 26 to fully engage and lock the lock portion 30 with the lock receiving portion 33, the engagement depth increases. The pressing protrusion 34 gradually and strongly presses the inclined receiving portion 35. Therefore, when the lock portion 30 is engaged deeply and locked, the pressing protrusion 34 presses the inclined receiving portion 35 to the rear of the inner frame 5, thereby forcibly retracting the game board 2 to a predetermined position. It is moved, and there is no back and forth play.
[0020]
Further, the game board lock mechanism 24 shown in FIG. 9 has a lock portion 30 of the lock member 25 formed in a bifurcated manner, and the lock receiving portion 33 is fitted between the lock portions 30 by the bifurcated lock portion 30 entering the recesses, respectively. An engagement piece 36 is provided. In the game board lock mechanism 24, when the lock member 25 is rotated by operating the operation unit 26, the bifurcated lock unit 30 enters the recesses with the engagement piece 36 interposed therebetween. When the lock receiving portion 33 is sufficiently rotated, the bifurcated lock portion 30 sandwiches and locks the engagement piece 36 and restricts the front and rear positions of the game board 2. Therefore, when the lock part 30 is engaged sufficiently deep and locked, the game board 2 is forcibly moved to a predetermined position and is locked in this state.
[0021]
In this way, the inner frame 5 provided with the game board locking mechanism 24 and the temporary fixing mechanism 20 for locking the game board 2 can be freely used as a locking member on the other side of the outer frame 6 by a hook constituting a part of the locking device. The end side is locked.
[0022]
Further, the clear member storage frame 3 is closed to a predetermined position (a normal position where it can be operated without any trouble) by lightly pressing it against the inner frame 5 side by hand if the game board locking mechanism 24 is converted to the locked state. The free end side is locked to the other side of the inner frame 5 by another hook 37 constituting the locking device. On the other hand, if the game board locking mechanism 24 remains in the non-locked state, even if the game board lock mechanism 24 is pressed by hand, it is prevented from closing to a predetermined position by the action of the clear member storage frame closing operation restricting mechanism 38, so The configuration is such that the lock mechanism 24 is in an unlocked state. When the clear member storage frame 3 is closed to a predetermined position, the hook 37 of the locking device locks the clear member storage frame 3 and is not locked when it cannot be closed to the predetermined position. The inner frame 5 and the clear member storage frame 3 are locked in such a manner that when the key inserted in the key hole of the cylinder lock 39 provided on the upper side of the inner frame 5 is rotated in one direction, the inner frame 5 is rotated in the other direction. Then, the clear member storage frame 3 is unlocked.
[0023]
Next, the closing operation of the clear member storage frame 3 is provided at a position where the inner frame 5 which is a frame and the clear member storage frame 3 face each other, that is, at the front side of the inner frame 5 and the back side of the clear member storage frame 3. The clear member storage frame closing operation restricting mechanism 38 that restricts the state in relation to the state of the game board lock mechanism 24 will be described.
[0024]
The clear member storage frame 3 is obtained by mounting a plate glass 11 or a transparent plastic plate as a clear member at a central opening of a synthetic resin frame body. On the back side, as shown in FIG. The through hole 61 through which the hook 37 of the locking device penetrates is formed in a part of the reinforcing member 60, and the edge of the through hole 61 is used as the engaging portion of the hook 37 so that the clear member storage frame 3 is rotated to the normal position. The protrusion length of the hook 37 and the position of the engaging claw portion 37 ′ are set so that the hook 37 engages with the engaging portion of the reinforcing member 60 when it moves and closes normally with respect to the inner frame 5. The front and rear positions of the engaging portion are set.
[0025]
Further, in this embodiment, a part of the reinforcing member 60 corresponding to the position where the operation unit 26 that functions as the movable contact unit 62 stops in the unlocked state is used as the fixed contact unit 63, and the operation unit 26 is in the locked state. A concave contact avoiding portion 64 capable of accommodating the protruding tip portion of the operation portion 26 is formed in a part of the reinforcing member 60 corresponding to the stop position. As shown in FIG. 10, the portion of the reinforcing member 60 that functions as the fixed contact portion 63 contacts the operation portion 26 (movable contact portion 62) in the unlocked state before the clear member storage frame 3 closes to the normal position. It is arranged at the position where it touches. On the other hand, as shown in FIG. 10, the contact avoiding portion 64 is formed in a concave shape with a sufficient depth so as not to contact the operation portion 26 in the locked state when the clear member storage frame 3 is closed at the normal position. is there.
[0026]
Therefore, when the operation part 26 of the game board lock mechanism 24 remains in the unlocked state and the clear member storage frame 3 that is wide open is pressed by hand toward the inner frame 5 side to start the closing operation, FIG. As shown in the figure, the fixed contact portion 63 on the clear member storage frame 3 side is the protruding tip portion of the operation portion 26 as the movable contact portion 62 before the clear member storage frame 3 reaches the normal position of the inner frame 5. At this time, the closing operation of the clear member storage frame 3 is prevented by the contact between the fixed contact portion 63 and the movable contact portion 62. For this reason, the front end portion of the clear member storage frame 3 remains protruding from the front surface of the inner frame 5, and an operator who is pressing the clear member storage frame 3 by hand to close the clear member storage frame 3 It can be recognized that it does not close to the predetermined position, that is, it has forgotten to lock the game board lock mechanism 24 and tried to close the clear member storage frame 3. Further, if the clear member storage frame 3 does not close to the normal position due to the contact between the fixed contact portion 63 and the movable contact portion 62, the hook 37 does not sufficiently penetrate into the through hole 61 of the reinforcing plate 60. There is no locking.
[0027]
When an operator who has forgotten to lock has opened the clear member storage frame 3 again and operates the operation unit 26 (in this embodiment, slides the operation unit 26 upward), the game board lock mechanism 24 is converted to the locked state. The game board 2 is locked. Then, when the closing operation is performed by manually pressing the clear member storage frame 3 again, the operation portion 26 (movable contact portion 62) is now opposed to the fixed contact portion 63 as shown in FIG. Since the contact avoiding portion 64 is formed at a position facing the operation portion 26 in this state, the clear member storing frame is moved away from the contact position. 3 is allowed to close to the normal position sufficiently deep with respect to the inner frame 5. In this manner, when the clear member storage frame 3 is rotated to the normal position and closed, the front surfaces of the clear member storage frame 3 and the inner frame 5 are substantially flush with each other, and the hook 37 penetrates the reinforcing plate 60. The hole 61 is sufficiently deeply penetrated, and the engaging claw 37 ′ of the hook 37 is engaged with the edge of the through hole 61 and locked by the bias of the spring. In this state, the operation part 26 of the game board lock mechanism 24 is housed in the contact avoiding part 64 and the movement is restricted. It will never be unlocked. Therefore, as long as the clear member storage frame 3 is closed, the locked state of the game board 2 is reliably maintained.
[0028]
In this manner, if the clear of the game board lock mechanism 24 is forgotten, the clear member storage frame 3 cannot be closed to a predetermined normal position. Therefore, if the clear member storage frame 3 is closed by hand, the user immediately realizes that the lock is forgotten. However, the game board lock state display means 70 is provided so that the lock state can be visually confirmed before the clear member storage frame 3 is closed.
[0029]
The game board lock state display means 70 shown in the drawing is a front running portion of the inner frame 5 to which the operation unit 26 is slidably attached, and appears when the operation unit 26 is not locked, and is hidden by the operation unit 26 when locked. In the part to be displayed, an indication “unlocked” indicating that it is in an unlocked state is written. Therefore, if the operation unit 26 is operated to convert to the locked state, as shown in FIG. 11B, the display of “open” is not visible to the operator, but forgets the lock and remains in the unlocked state. Then, as shown in FIG. 11A, “open” remains displayed, and a visual indication that the operator is in the unlocked state (open) is displayed. Therefore, the operator can confirm the lock of the game board 2 only by confirming the “open” display when the clear member storage frame 3 is closed.
[0030]
The game board lock state display means 70 is configured so that the display changes depending on whether the game board lock mechanism 24 is locked or not, and the operator can visually check the lock state of the game board 2. Any configuration is possible. For example, a portion that is covered by the operation unit in the locked state and appears after the operation unit is released in the unlocked state may be colored red.
[0031]
Next, the game board 2 to be mounted on the game board mounting portion 9 of the inner frame 5 will be described.
As shown in FIG. 12A, the game board 2 is partitioned by a partition member such as a guide rail to form a game unit 10 on the front surface, and innumerable obstacle nails 40 and winning devices 41 are formed in the game unit 10. Etc. are provided. The game board 2 in the present embodiment is molded into a hollow, substantially rectangular plate-like body as a whole by using a synthetic resin, and the substantially circular gaming part 10 is formed in a concave shape on the front face part 43 surrounded by the edge part 42 of the upper, lower, left, and right four rounds. The curved surface between the circular inner edge of the front surface portion 43 and the outer edge of the game surface 44 functions as a partition member, and the inner guide rail 45 is fixed inside a part of the partition member to thereby provide a ball guide channel. 46 is formed, and an out port 47 is opened at the lowest position in the gaming unit 10 surrounded by the inner guide rail 45 and the partition member, and the obstacle nail 40 is planted in the gaming unit 10 to serve as a center. An object 48, a variable display device, and a winning device 41 are provided.
[0032]
In the present embodiment, an out ball flow path 49 is formed in the lower part of the back side of the out port 47 so that the out ball can be processed within the thickness of the game board 2. In addition, a convex portion 50 for supporting the root of the obstacle nail 40 is integrally formed on the back side of the game surface 44 where the obstacle nail 40 is implanted. Therefore, even if the metal obstacle nail 40 is implanted on the synthetic resin game surface 44 (insert molding or separately driven), the obstacle nail 40 can be firmly supported, and the nail is adjusted. It will not be damaged by impact.
[0033]
Further, the game board 2 in the present embodiment is provided with a rotation support shaft 51 on the same center line on one side corresponding to the bearing part (shaft hole 23) provided on the game board mounting part 9, and the game is provided on the other side. In addition to providing a suctioned part 22 that constitutes a part of the temporary fixing mechanism 20 that can be held in the board mounting part 9, a lock receiving part 33 that constitutes a part of the game board locking mechanism 24 is provided.
[0034]
As shown in FIG. 14, the rotation support shaft 51 is a substantially L-shaped shaft formed at one end with a portion that becomes the operation portion 52, and the operation portion extends from the long hole 53 formed in the front portion 43 of the game board 2. 52 faces the front surface of the game board 2 and is mounted in a state of protruding from holes formed in the upper edge surface and the lower edge surface. And the axial part is urged | biased by the elastic force of the spring 55 connected to the bending part between the axial part and the operation part 52 in the direction which protrudes from the hole of an upper edge surface (lower edge surface). Therefore, in a natural state where the operation portion 52 is not operated, the shaft portion largely protrudes from the hole due to the urging of the spring 55, and the rotation support shaft 51 is operated by operating the operation portion 52 against the urging of the spring 55. As it moves, the length protruding from the hole decreases. Therefore, one side of the game board 2 can be inserted into the game board mounting portion 9 with the protruding length reduced. Then, when the hand is released from the operation portion 52, the rotation support shaft 51 is moved by the bias of the spring 55, the protruding length is increased, and the extended shaft end is fitted into the bearing portion of the game board mounting portion 9. Match.
[0035]
As shown in FIG. 6, the attracted portion 22 of the temporary fixing mechanism 20 provided in the game board 2 is disposed at a position corresponding to the permanent magnet 21 of the temporary fixing mechanism 20 provided in the game board mounting portion 9. In this embodiment, the iron plate is bent into a substantially convex shape, and a screw is passed through the mounting hole formed in the flange portion 56, and the screw is attached to the back surface of the game board 2. It is fixed by screwing into the mounting hole of the protruding boss 57. Since the rear end surface of the attracted portion 22 is attracted to the permanent magnet 21, the rear end surface is adjusted to the virtual back surface of the game board 2 according to the thickness of the game board 2.
[0036]
Next, a game board mounting procedure for mounting the game board 2 having the above-described configuration on the game board mounting portion 9 of the inner frame 5 will be described. For convenience of explanation, it is assumed that the game board 2 that has been mounted so far has already been removed.
[0037]
As shown in FIG. 4, the pachinko gaming machine 1 from which the game board 2 has been removed has the clear member storage frame 3 and the open / close panel 4 opened widely, and the operation part 26 of the game board lock mechanism 24 is lowered. Since it is converted to the non-locked state, “open” of the game board lock state display means 70 is displayed. The game board 2 to be newly installed in this state is lifted with the game unit 10 facing forward, and one side of the game board 2 on the side of the rotation support shaft 51 is loaded into the game board installation unit 9. At this time, by operating the upper and lower operation portions 52 of the rotation support shaft 51, the protruding length of the rotation support shaft 51 protruding up and down is shortened and inserted.
[0038]
If the lower rotation support shaft 51 side is inserted before the upper side, the lower rotation support shaft 51 can be inserted without shortening. Therefore, the lower rotation support shaft 51 may remain fixed, that is, the protrusion length may not be adjusted. If it remains fixed, the structure is simplified, the manufacturing process is simplified, and the cost is reduced. Further, the game board mounting portion 9 may be provided with a rotation support shaft 51, and the game board 2 may be provided with a shaft hole 23 into which the rotation support shaft 51 is fitted. If comprised in this way, since the part which protrudes in the game board 2 decreases, handling will also become easy including conveyance from a factory.
[0039]
In this way, if one side of the game board 2 on the side of the rotation support shaft 51 is inserted into the game board mounting part 9, the position is adjusted and the hand is released from the operation part 52. Since the rotation support shaft 51 is urged by the spring 55, when the operation portion 52 is released, the upper and lower shaft portions are extended and fitted into the bearing portion (shaft hole 23) of the game board mounting portion 9. To do. Accordingly, the game board 2 is pivotally attached to the game board mounting portion 9 in a rotatable state by the rotation support shafts 51 provided on the upper and lower sides of one side.
[0040]
In this state, when the free end side of the game board 2 is pressed by hand to the game board mounting portion 9 side, the game board 2 rotates in the horizontal direction around the rotation support shaft 51. In this way, when one side of the game board 2 is pivotally attached by the rotation support shaft 51 and the shaft hole 23, a member such as a center accessory 48, a variable display, a large prize winning device, or the like protrudes from the back side of the game board 2. Alternatively, even if parts protrude at a position where the gap between the opening edge of the opening portion of the game board mounting portion 9 is small, the alignment work is performed so that these protruding members enter the opening portion 16 of the game board mounting portion 9. Even if it is not performed, the projecting portion is naturally inserted into the opening 16 simply by rotating the game board 2 around the rotation support shaft 51. Therefore, this also contributes to facilitating the mounting work of the game board 2.
[0041]
If the clearance between the opening 16 of the game board mounting portion 9 and the member protruding to the back side of the game board 2 can be set smaller than the conventional design, it protrudes to the back side of the game board 2. Since the members can be arranged in a wider range than before, the degree of freedom of design is increased, and the fun of the game can be enhanced by devising the arrangement of the parts in the gaming unit 10. In addition, there is a wiring cord on the back side of the game board 2, and it may be necessary to pass this wiring code through the opening 16 of the game board mounting part 9. If the shaft 51 is attached to the shaft, the operation of passing the wiring cord through the opening 16 can be efficiently and safely performed with both hands.
[0042]
When the game board 2 is sufficiently rotated, the edge part 42 of the game board 2 abuts on the positioning part 17, the vertical and horizontal positions of the game board 2 are regulated, and the game board 2 is guided to a predetermined position. Further, when the game board 2 is sufficiently rotated and pressed, the rear end edge of the edge surface portion 42 comes into contact with the positioning portion 17 and the retracted position is also restricted. Furthermore, when the game board 2 is guided to a predetermined position by the action of the positioning part 17, the attracted part 22 provided on the back side of the game board 2 abuts against the permanent magnet 21 on the game board mounting part 9 side. Since they are close to each other, the attracted portion 22 is attracted by the attracting force of the permanent magnet 21. Therefore, even if the operator releases his / her hand, the game board 2 is temporarily fixed in the game board mounting portion 9 by the attraction force of the permanent magnet 21 and maintains its state. For this reason, if the worker puts the game board 2 into the game board mounting portion 9 for the first time, the worker can release his / her hands with peace of mind, and can perform other work as necessary.
[0043]
If the game board 2 is temporarily fixed by the above-described temporary fixing operation, the operation unit 26 of the game board lock mechanism 24 provided on the front surface of the inner frame 5 is then operated. When the operation unit 26 is operated, as described above, the lock member 25 of the game board lock mechanism 24 rotates about the shaft 31, the lock part 30 engages with the lock receiving part 33 of the game board 2, The game board 2 can be locked at a predetermined position. When the operation unit 26 is operated to convert the game board lock mechanism 24 to the locked state, the display of “open” is covered by the operation unit main body 27.
[0044]
When the game board 2 is locked, the remaining work such as connecting a wiring cord of a member attached to the game board 2 to a predetermined connector is performed. When this work is performed, the work is performed on the back side of the inner frame 5, but since the game board 2 is already locked to the inner frame 5 side, an unnatural posture such as pressing the game board 2 with one hand is taken. There is no need, and both hands can work in a natural posture on the back side of the inner frame 5.
[0045]
As described above, in this embodiment, the rotation support shaft 51 is provided on one side of the game board 2, and the temporary fixing mechanism 20 for temporarily fixing the game board 2 is provided, and the operation of the game board lock mechanism 24 is performed. Since the portion 26 is provided on the front surface of the inner frame 5, when the game board 2 is mounted on the game board mounting portion 9 of the inner frame 5, work is performed without breaking the natural posture from the front side of the pachinko gaming machine 1. be able to. Therefore, it is excellent in workability. Moreover, since the game board 2 is temporarily fixed only by pushing the game board 2 into the game board mounting portion 9, even if the weight of the game board 2 increases, the work can be easily performed. In addition, work safety can be improved.
[0046]
Then, when the work of mounting the game board 2 on the game board mounting part 9 of the inner frame 5 is finished and the clear member storage frame 3 is closed, the game part 10 of the game board 2 can be seen through the plate glass 11 of the clear member storage frame 3. It becomes a state. The operation unit 26 of the game board lock mechanism 24 is disposed on one side of the front surface of the inner frame 5, but when the clear member storage frame 3 is closed, the operation unit 26 is covered with the clear member storage frame 3. It is. Therefore, the operation unit 26 is not visible from the player side, and even if the operation unit 26 is provided on the front surface of the inner frame 5, the appearance of the pachinko gaming machine 1 is not impaired. Also, the operation of the game board lock mechanism 24PartWhen the clear member storage frame 3 is closed when the lock member 26 is not in a locked state, that is, in a unlocked state or in an incomplete lock state, the operation unit 26 protruding forward hits the clear member storage frame 3 to the normal position. Since it does not close, it is possible to prevent forgetting lock or incomplete lock.
[0047]
In the above-described embodiment, the operation part 26 of the game board lock mechanism 24 is a slide type, and the operation part 26 is provided in a state protruding from the front surface of the inner frame 5 to be the movable contact part 62. The contact portion 62 changes in position and protrusion length according to the state change between the locked state and the unlocked state of the game board lock mechanism 24, and contacts the fixed contact portion 63 in the locked state. Any configuration may be used as long as it deviates from the contact position of the fixed contact portion 63 in the state. For example, a lever-type operation unit (not shown) is pivotally attached to the front surface of the inner frame 5 and when this lever is triggered, the movement of the lever is transmitted to the lock unit 30 by a transmission member such as a link mechanism to make it unlocked. When the lever is tilted (substantially parallel to the front surface of the inner frame 5), the lever standing up in the unlocked state comes into contact with the fixed contact portion 63 of the clear member storage frame 3 so as to convert to the locked state. Accordingly, the closing operation of the clear member storage frame 3 may be restricted, or a dial type operation unit (not shown) having a convex portion is provided, and the convex portion whose position changes with state conversion is provided. The movable contact portion 62 may be used.
[0048]
Further, the movable abutment portion 62 is not limited to the operation portion 26 itself, and the position, protrusion length, and the like change as the game board lock mechanism 24 changes between the locked state and the unlocked state. If the closing operation of the clear member storage frame 3 can be restricted by contacting the fixed contact portion 63 in the locked state, a member whose position and protrusion length change in conjunction with the movement of the operation portion 26 may be separately provided. .
[0049]
On the other hand, the fixed contact portion 63 that contacts the movable contact portion 62 is provided on the back side of the clear member storage frame 3 and contacts the movable contact portion 62 only when the clear member storage frame 3 is in the unlocked state. As long as the closing operation can be stopped before the normal position, the structure is not limited to a part of the reinforcing member 60 of the clear member storage frame 3, and any configuration may be used. For example, it may be provided separately from the reinforcing member 60 on the back side of the clear member storage frame 3 or may be integrally formed with the clear member storage frame 3.
[0050]
Further, the temporary fixing mechanism 20 is not limited to the above-described embodiment, and is disposed at a position where the game board 2 and the game board mounting part 9 face each other, and the pressing force from the game board 2 to the game board mounting part 9 As long as the game board 2 can be held by generating resistance to movement in the opposite direction (that is, the direction in which the game board 2 is removed), any configuration may be used. For example, one hook-and-loop fastener is attached to the back side of the game board 2, for example, the back of the attracted portion 22 integrally molded with the game board 2, and the other hook-and-loop fastener is attached to the inner surface of the game board mounting portion. It may be configured such that when the board 2 is pressed, the surface fastener of the game board 2 is fastened to the surface fastener on the side of the game board mounting portion 9 so that the game board 2 can be temporarily fixed. A hook-and-loop fastener consists of, for example, an infinite number of small hoops formed on the base surface and an infinite number of small hooks projecting from the base surface. There are members that generate resistance, a plurality of small protrusions instead of hooks and hoops, step portions that can be engaged with the small protrusions, and members that engage the small protrusions. In this manner, when a hook-and-loop fastener is used for the temporary fixing mechanism, there is no possibility of magnetizing the iron game ball because it is not affected by the magnetic force.
[0051]
In addition, an elastic locking claw is provided on the back surface of the game board 2, and a receiving step portion capable of locking the elastic locking claw is provided in the game board mounting portion 9, and the engagement between the receiving step portion and the elastic locking claw is provided. The game board 2 may be configured to be temporarily fixed.
[0052]
Moreover, although the embodiment demonstrated so far demonstrated the pachinko game machine 1, this invention is not limited to the pachinko game machine 1, The ball game provided with the game board 2 in which the game part 10 was formed. Any gaming machine may be used as long as it is a machine. For example, a sparrow ball game machine or a smart ball game machine may be used. Further, the frame on which the game board 2 is mounted is not limited to a synthetic resin, and may be wooden.
[0053]
【The invention's effect】
  As described above, according to the present invention, when the game board is mounted on the game board mounting portion of the frame body, the operation unit of the game board lock mechanism is disposed on the front surface of the frame body. Can be locked. And if you forget to lock the game board and try to close the clear member storage frame, this clear member storage frame will not close to the normal position by the clear member closing operation restriction mechanism, this clear member closing operation restriction mechanism IsOperation part of the game board lock mechanism andSince the closing operation of the clear member storage frame is regulated by contact with the fixed contact portion provided on the back side of the clear member storage frame, forgetting to lock can be reliably prevented with a simple structure. Therefore, it is possible to efficiently perform the game board replacement work, not only finish the work of a large number of ball game machines in a short time, but also reliably forget to lock the game board of each ball game machine. Can be prevented. If it is possible to reliably prevent the game board from being forgotten to be locked, the connection between the game board and the other parts can be performed reliably, and the game board can be stabilized without rattling.
[0054]
Also,The locked state and the unlocked state of the game board can be visually confirmed by the game board lock state display means. Therefore, it is possible to confirm the lock of the game board without closing the clear member storage frame.
