Description

【０００１】
【発明の属する技術分野】
この発明は、遊技機の遊技盤に関し、特に遊技機本体から遊技盤のみを取り外して交換可能な所謂分離式遊技機の遊技盤に関するものである。
【０００２】
【従来の技術】
遊技機の遊技盤において、打球発射装置から発射される打球は、発射レールからファール玉樋を飛び越えて外レールに飛び移り、この外レールに導かれて遊技部に飛入する。そして、従来の外レールは、一般に、基端部分を折曲加工して固定釘が通る筒状固定部を形成し、この固定部に通した固定釘をベニア合板からなる遊技盤本体に打ち込んで固定していた。また、従来の外レールは、適宜な間隔で下縁に係止させた割ピンを遊技盤本体に打ち込んで固定していた。
一方、打球をガラス面や遊技盤面に衝接させないで遊技部へ誘導するには、固定した外レールを遊技盤本体に対して所定の角度で起立させなければならない。そこで、外レールの取付角度を、上記した固定釘を側方からハンマー等で叩いて調整していた。
【０００３】
【発明が解決しようとする課題】
しかしながら、遊技盤本体に対して強固に固定されている従来の外レールに、打球が衝突すると、打球の着地点が激しく摩耗してしまう現象が発生していた。
また、従来の外レールにおいて、角度調整、即ち遊技盤面に対する起立状態を調整するには、前記したように固定釘をハンマー等で叩いて行っていたので、熟練技術を必要としていた。また、この調整作業は、狭い作業空間で行わなければならないため、誤って他の部材や組立機械を叩いてしまい、当該遊技盤を使用不能にしたり、組立機械を破損することもあった。
本発明は上記に鑑み提案されたもので、外レールの摩耗を防止可能な遊技盤を提供することを目的とする。
【０００４】
【課題を解決するための手段】
上記目的を達成するため請求項１に記載した発明は、遊技盤本体に外レール及び内レールを立設して、打球が流下する遊技部と該遊技部の外側に位置する非遊技部とを区画形成し、遊技機に交換自在に装着する遊技盤であって、前記遊技部を形成するほゞ円形の第１空部及び該第１空部の周辺に設けた非遊技部を形成するベース板部を備える第１飾りベース部材と、ほゞ円形の第２空部を設けた第２飾りベース部材と、を設け、前記第１飾りベース部材の第１空部の外縁には、外レールの遊技盤本体側の側縁を受け入れる受溝及び外側起立片を、打球発射装置から発射された打球が衝突する着地点の周囲を除いて跳ね返りゴムの位置まで設け、前記第２飾りベース部材の外レールを取り付ける側には、外レールの背面側に位置する支持片を円弧状に設け、外レールの遊技盤本体側の側縁を第１飾りベース部材の受溝に嵌合させ、且つ外レールを第２飾りベース部材の前記支持片に沿わせて、第１飾りベース部材と第２飾りベース部材との間に外レールを組み付けることにより、打球を遊技部に誘導するように外レールをほゞ円弧状に配設し、前記第１飾りベース部材に、外レールの打球発射装置側の基端を固定する外レール固定金具を設け、打球が衝突する着地点付近の外レールの側縁を第１飾りベース部材及び第２飾りベース部材に接触させないように、外レールの打球発射装置側の基端付近に切欠を設けて外レールの幅を狭くすると共に、打球が衝突する着地点付近の前記起立片及び支持片を若干後退させて段差部を設け、外レールの背面側に前記段差部による空間を形成し、外レールに打球が衝突したとき、外レールの変形を許容するようにしたものである。
請求項２に記載した発明は、遊技盤本体に外レール及び内レールを立設して、打球が流下する遊技部と該遊技部の外側に位置する非遊技部とを区画形成し、遊技機に交換自在に装着する遊技盤であって、前記遊技部を形成するほゞ円形の第１空部及び該第１空部の周辺に設けた非遊技部を形成するベース板部を備える第１飾りベース部材と、ほゞ円形の第２空部を設けた第２飾りベース部材と、を設け、前記第１飾りベース部材の第１空部の外縁には、外レールの遊技盤本体側の側縁を受け入れる受溝及び外側起立片を、打球発射装置から発射された打球が衝突する着地点の周囲を除いて跳ね返りゴムの位置まで設け、前記第２飾りベース部材の外レールを取り付ける側には、外レールの背面側に位置する支持片を円弧状に設け、外レールの遊技盤本体側の側縁を第１飾りベース部材の受溝に嵌合させ、且つ外レールを第２飾りベース部材の前記支持片に沿わせて、第１飾りベース部材と第２飾りベース部材との間に外レールを組み付けることにより、打球を遊技部に誘導するように外レールをほゞ円弧状に配設し、前記第１飾りベース部材に、外レールの打球発射装置側の基端を固定する外レール固定金具を設け、打球が衝突する着地点付近の外レールの側縁を第１飾りベース部材及び第２飾りベース部材に接触させないように、外レールの打球発射装置側の基端付近の第１飾りベース部材及び第２飾りベース部材に切欠又は溝を形成すると共に、打球が衝突する着地点付近の前記起立片及び支持片を若干後退させて段差部を設け、外レールの背面側に前記段差部による空間を形成し、外レールに打球が衝突したとき、外レールの変形を許容するようにしたものである。
請求項３に記載した発明は、前記外レール固定金具は、嵌着孔を開設した装着片を備え、この装着片に外レールの打球発射装置側の基端に設けた止着部を装着し、外レールの止着部に設けたダボを前記装着片の嵌着孔に嵌入させることにより、前記外レールの打球発射装置側の基端を、前記外レール固定金具を介して固定するようにしたものである。
【０００５】
【発明の実施の形態】
以下、本発明を図示の一実施例について説明する。図１は遊技機、即ちパチンコ機の概略を示す正面図及び側面図である。
【０００６】
パチンコ機１は、一般に窓部を有する額縁状の前枠１１の一側を外枠１２に開閉可能に蝶着し、上記窓部にはガラスを装着したガラス飾り枠１３を開閉可能に軸着し、上記前枠１１及びガラス飾り枠１３を施錠装置１３１で施錠する。図面では図示していないが、ガラス飾り枠３の背面には遊技盤本体２７の前面を被うガラスを装着するガラス枠が設けてあり、額縁状に形成されるガラス飾り枠１３の開口部を塞ぐようにしてある。また、ガラス飾り枠１３の下方部分には上皿１４１を設けたフロントプレート１４２等からなる上受皿セット１４を設け、前枠１１の下方部分には下皿１５１を設けた下受皿セット１５を設ける。尚、上記上受皿セット１４の裏面側の遊技盤載置台１６（図２参照）には上皿１４１から打球発射装置１６１へ球を一個宛に供給する球送り装置１６２やスピーカが位置し、スピーカが発する効果音は上皿１４１の下方に設けたスリット１４３を通して聴こえる。尚、上記打球発射装置１６１はソレノイドを駆動源として杵先１６３で球発射位置にある球を打ち出す。上記上皿１４１の前面部分には、当該上皿１４１の球を下皿１５１に排出させるための球抜きボタン１４４を設ける。更に、図示のパチンコ機１では、可変図柄表示装置（図示せず）の図柄を停止させるためのタッチスイッチ１４５が設けてある。
【０００７】
上記前枠１１の窓部には、この窓部を塞ぐように遊技盤載置台１６に載せて交換可能に構成した遊技盤２を臨ませる。遊技盤２の前面側には後述する外レール３１及び内レール３２を配設してほゞ円形に囲まれる遊技部２１を形成する。また、この遊技部２１内には、図示していないが、可変表示装置や変動入賞装置等の各種役物、始動口や各種入賞具、風車、或は各種表示灯等、様々な遊技部材を配設し、最下位置にアウト口２２を設ける。更に、外レール３１または内レール３２の外側で右側の上方隅部分には完了表示灯２３を、外レール３１の外側で左側の上方隅部分には賞球表示灯２４を設け、更にガラス飾り枠１３の上縁には外部表示灯２５を設ける。尚、以後、外レール３１及び内レール３２の外側を非遊技部２６という。
【０００８】
上記下受皿セット１５の前面側には打球発射装置１６１により遊技部２１に打ち込まれる打球の飛距離を調整するための操作グリップ１５２を設ける。また、この下受皿セット１５には、獲得した賞球を貯留しておくための下皿１５１の他、灰皿１５３や球抜きレバー１５４等が設けてある。
【０００９】
上記のような諸装置或は諸部材を組み付ける前枠１１は、ベニヤ合板等を切削加工して構成してもよいし、合成樹脂を成形して構成してもよい。また、前枠１１をヒンジ装置により蝶着する外枠１２は、木板等を矩形に枠組したもので、図示の実施形態では接続隅部に補強金具１２１を設けている。尚、前枠１１の側縁には、施錠装置１３１のレバーや鍵片の逃げとして凹部１２２，１２３及び錠受金具１２４が設けてある。
【００１０】
遊技盤２は、パチンコ機１の主要な部材であって、ベニヤ合板の全前面に意匠図の描かれた図示しないセルシートを一体に結合したほゞ方形の遊技盤本体２７に種々の遊技部材を取り付けて構成する。この遊技盤本体２７は、例えばベニヤ合板を切削加工して形成する。尚、図面では開口部や取付孔等の図示を省略している。
【００１１】
遊技盤本体２７の前面側には、後述する飾り部材３を添設して遊技部２１と非遊技部２６とを形成する。即ち、遊技者が発射した打球が転動する部分と、打球が飛び出すことがなく、専ら表示及び装飾に用いる部分とに区画する。このため、従来の遊技盤２においては、「ガイドレール」或は「バンド」等と呼ばれる帯状のステンレス板をほゞ円形ないし渦巻状に配置すると共に、割ピンを遊技盤本体２７に打ち込んで固定していた。
【００１２】
このため、従来のパチンコ機１にあっては、上記ガイドレールを所定の形状に、即ち正しい曲線を描くように、且つ盤面に対して直立するように、固定するのが困難であった。また、ガイドレールの側端縁（切口）が露出しているので、清掃時等に怪我をする虞れがあった。
【００１３】
そこで、図面の実施形態では、遊技盤本体２７とほゞ同形に形成した第１飾りベース部材４と第２飾りベース部材５とから構成する飾り部材３を、遊技盤本体２７の前面側に重合させることにより、遊技部２１と非遊技部２６とを形成している。
【００１４】
第１飾りベース部材４は、遊技盤本体２７とほゞ同形、換言すると外形線が一致する形状に構成した板状の部材であって、光透過性の合成樹脂により一体成形する。このことにより遊技盤本体２７の意匠図が透過して見える。この第１飾りベース部材４の中央部分には、遊技部２１となるほゞ円形の第１空部４１を設け、遊技盤本体２７の表面部分が見えるようにする。
【００１５】
上記第１空部４１の周辺部には、非遊技部２６を形成するためのベース板部４２を設ける。また、ベース板部４２の内縁、即ち上記第１空部４１の外縁には、後述する外レール３１の支えとなり、外レール３１を装着可能な第１外レール装着部を形成する。この第１外レール装着部は、例えば外側起立片４３、及び外レール３１の厚さ分の間隔をあけて突設した突条４４とからなる。
【００１６】
外側起立片４３は、後述する外レール３１の基端（先端）が位置する図面に向って左側下方の左下ベース板部４２１から第１空部４１の側縁に沿って始まり、左側上方の左上ベース板部４２２へ円弧を描いて連なり、右側上方の右ベース板部４２３における跳ね返りゴム４５の位置にて終了する。この外側起立片４３の基端部分の内側には、前記したように外レール３１の側縁を受け入れる受溝４３１を形成するための突条４４を平行して設ける。
【００１７】
また、第１飾りベース部材４には、内レール３２として機能する内側起立片４６を設ける。この内側起立片４６は、前記した外レール装着部、即ち外側起立片４３と一部が重なるように打球が通過可能な空隙を開けて第１空部４１の側縁部に形成している。尚、図示の実施形態においては、内側起立片４６が内レール３２として直接機能するのは遊技部２１の左方部分であり、下方部分は後述する不正遊技防止部材６が内レール３２の下方部分を形成しているが、不正遊技防止部材６を取り付けないときは、内側起立片４６が内レール３２として機能する。
【００１８】
一方、上記内側起立片４６と対向する側、即ち遊技部２１の右側には、内側垂下片５４を設けて内レール３２として機能させる。即ち、第２飾りベース部材５の第２空部５１の周辺に設けた前面板部５２の跳ね返りゴム４５の位置から遊技盤面へ向けて円弧状に始まり、右下ベース部５２１を通ると共に、最下位置のアウト口２２となる凹部５３の左端で終る。尚、図示の実施の形態では、直接内レール３２として機能するのは、遊技部２１の右方部分であって、下方部分は後述する不正遊技防止部材６を添設するようなっている。
【００１９】
上記外側起立片４３と内側起立片４６とが重なる部分は、遊技者が発射する打球の通路、即ち球通路４７となる部分で、底板部４７１により繋がっており、入口側が幅広に形成されると共に、出口側が縮幅している。また、出口部分の底板部４７１の先端は、傾斜面４７２によって斜めに遊技盤面に連なるようになっており、打球がスムーズに遊技部２１に飛入する。
【００２０】
上記打球の出口部分、即ち内側起立片４６の先端には、戻り玉防止装置４８を設ける。この戻り玉防止装置４８は、図示の実施形態によれば、内側起立片４６の先端に弾性を有する戻り玉防止片４８１、例えばステンレスの箔片を、球通路４７を斜めに横切るように交換自在に装着して構成する。従って、打球が障害釘や跳ね返りゴム４５に衝突して跳ね返っても、上記戻り玉防止片４８１にぶつかると、当該戻り玉防止片４８１が球通路４７の出口を塞ぐので、跳ね返り球は球通路４７を逆流することがない。一方、打球は戻り玉防止片４８１を開いて遊技部２１に飛入する。
【００２１】
また、この戻り玉防止装置４８においては、戻り玉防止片４８１が交換自在に構成してある。即ち、内側起立片４６の先端に、厚肉部４８２を形成すると共に、該厚肉部４８２に一部が開口して円筒形の基端装着部４８３に連通する装着溝４８４を形成する。一方、戻り玉防止片４８１の基端を丸めて上記基端装着部４８３に装着可能な装着柱４８５を設ける。そして、この装着柱４８５を上記基端装着部４８３に挿入すると共に、戻り玉防止片４８１を開口を通して厚肉部４８２の上方へ延出させる。従って、戻り玉防止片４８１が変形してしまったような場合には、上記装着柱４８５を基端装着部４８３から抜き去り、新しい戻り玉防止片４８１を基端装着部４８３に挿入して交換すればよい。
【００２２】
上記戻り玉防止装置４８は、図６に示すように他の実施の形態とすることもできる。この実施の形態では、後述する不正遊技防止部材６を延長することにより戻り玉防止装置４８を構成している。即ち、内レール３２を構成する内側起立片４６に沿って取り付ける不正遊技防止部材６の先端に戻り玉防止片６８１を一体に形成し、当該戻り玉防止片６８１の基端部に設けた嵌着孔６８２に、第１飾りベース部材４の底板部４７１から起立する嵌着ピン４８１を嵌合させて、不正遊技防止部材６及び戻り玉防止片４８１を取り付けたものである。
【００２３】
このような構成の戻り玉防止装置４８によっても、打球が遊技部２１で跳ね返って球通路４７に飛び込もうとしても、戻り玉防止片６８１が球通路４７の出口を塞いでいるので、戻り玉の発生を確実に防止できる。一方、発射された打球に対しては戻り玉防止片６８１が抵抗になることはなく、スムーズに打球を遊技部２１へ飛入させる。
【００２４】
尚、戻り玉防止片４８１及び不正遊技防止部材６の先端部の固定は、図６（Ｂ）に示すように、第１飾りベース部材４から起立させた板状の嵌着片４８３に戻り玉防止片６８１の基端部分に開設した嵌着口６８３を嵌合させるようにしてもよい。この図６に示した実施の形態においては、不正遊技防止部材６を戻り玉防止装置４８に向けて次第に縮幅させてテーパー状に配設してある。
【００２５】
更に、図７に示す実施の形態は、不正遊技防止部材６に内側起立片４６を覆う被覆部６０を先端部に向けて延設し、該被覆部６０の先端に戻り玉防止装置４８を設けたものである。尚、上記した各実施の形態においては不正遊技防止部材６と戻り玉防止装置４８を一体に構成しているが、分離して戻り玉防止装置４８のみを交換可能にすることもできる。
【００２６】
第１飾りベース部材４の左右側縁には、遊技盤２を遊技機本体に取り付けるときに利用するロック受３３を設ける。このロック受３３は、第１飾りベース部材４の所定の位置に凹陥部３３１を形成すると共に取付基部３３２を設け、この取付基部３３２に金属片からなるロック片３３３の先端と第１飾りベース部材４の側縁とを合わせると共に、後述する第２飾りベース部材５の下面との間に遊技盤取付装置（図示せず）の取付片を受け入れる取付空部３３４をあけるように取り付けて構成する（図１８参照）。尚、遊技盤取付装置は回動可能に軸着したコ字状の取付片で、遊技盤２の側縁を挟み込んで当該遊技盤２を取り付けるようにしたもので、遊技盤２の周囲４箇所に設けてある。
【００２７】
打球発射装置１６１で発射される打球は、発射レール１６４からファール玉樋１６５を飛び越えて外レール３１に飛び移り、この外レール３１に導かれて遊技部２１に達する。そして、前記したように、従来のパチンコ機における外レールは、基端部分を折曲加工して固定釘が通る筒状固定部を形成し、この固定部に通した固定釘をベニヤ合板からなる遊技盤本体に打ち込んで固定していた。このため、強固に固定された外レールに打球が衝突して、打球の着地点が激しく摩耗してしまっていたのが現状である。
【００２８】
そこで、本発明に係る遊技盤２は、外レール３１自身で打球の衝撃を吸収可能なように構成している。即ち、打球が衝突する着地点の周囲を自由空間として、外レール３１の変形を可能としている。
【００２９】
このため、本発明に係る遊技盤２では、外レール３１の基端付近に切欠部３１１を設けて幅を狭くして、側縁が遊技盤面側に接触しないように、且つ幅を狭くすることにより変形し易くして衝撃の吸収が大きくなるように構成している（図１０参照）。
【００３０】
また、外レール３１が変形するときの逃げとなる自由空間を形成するために、外側起立片４３の基端部分、即ち打球発射装置１６１から発射された球が衝突する部分及びその前後の適宜な範囲を、外レール３１と密着しないように若干後退させて段差部４３２を設ける。
【００３１】
具体的には、図５に示すように、外レール３１の背面側に空間Ｐが生じるように、外レール３１の取付位置よりも若干後退させた位置に外側起立片４３の段差部４３２を設ける。また、外レール３１の基端を固定するときには、後述する外レール固定金具７を介して固定する。
【００３２】
上記のようにして固定した外レール３１の先端部分においては、外レール固定金具７と外側起立片４３が始まる段差部４３２の範囲では、外レール３１が浮き上がった状態となる。このため、打球発射装置１６１から発射した打球が衝突しても、外レール３１の変形によって衝撃が緩和されることになるので安定した球飛びが得られる。また、外レール３１が強固に固定されていないので、球の衝突による外レール３１の摩耗も防止され、当該外レール３１の耐久性が向上する。
【００３３】
尚、前記した図示の実施の形態においては、外レール３１の基端付近に切欠部３１１を設けて幅を狭くすることにより、外レール３１が遊技盤即ち第１飾りベース部材４及び第２飾りベース部材５に接触しないように構成しているが、外レール３１の幅をそのままにして、第１飾りベース部材４及び第２飾りベース部材５に切欠や溝等を形成して、外レール３１の側縁が接触しないようにしてもよい。
【００３４】
更に、前記したように従来の遊技盤においては、外レール３１の基端を固定釘によって遊技盤本体に直接固定していた。従って、固定には熟練技術を要すると共に、角度調整も難しく、なかなか安定した球飛びを得られないのが現状であった。そこで、この実施の形態では、別部材として形成した外レール固定金具７によって、外レール３１の基端を固定基板７２に対して固定するようにした。
【００３５】
外レール固定金具７（図９参照）は、固定基板７２として機能する第１飾りベース部材４に設けたベース板部４２、図示の実施形態では球通路４７の底板部４７１に、裏面側からビス等によって固定する金具であり、外レール３１の先端に設けた止着部３１２を装着する装着片７１を備える。この装着片７１は、取付基板７４を切り起こして形成したもので、嵌着孔７５が開設してある。尚、取付基板７４には取付ビスを通す取付孔７４１や位置決め孔７４２を設ける。また、取付基板７４の下縁の一部には第１飾りベース部材４のベース板部４２の下縁部分を巻くように屈曲させた屈曲係止片７６が設けてあり、遊技盤２を遊技盤載置台１６に載せて設置するときに使用する係止金具の係止リング（図示せず）が係止する。更に、取付基板７４の下縁隅には、遊技盤２を遊技盤載置台１６に設置した場合に、発射レール１６４の基端との間に生じる隙間を塞ぐように立上り閉止片７７を設け、この閉止片７７により怪我をしないように保護キャップ７８を被せている。
【００３６】
外レール３１の基端には止着部３１２を形成する（図２参照）。この止着部３１２は、外レール３１の基端を折り返して形成したもので、上記外レール固定金具７の装着片７１を挟着することで、外レール３１の基端を固定するものである。尚、止着部３１２にはダボ３１３を設け、このダボ３１３が上記装着片７１の嵌着孔７５に嵌入して位置決め及び抜け止めを行うようになっている（図９，図１０参照）。
【００３７】
外レール３１が遊技盤本体２７に対して所定の角度、即ち直角に立ち上がっていないと、打球がガラスＧの方向へ飛んだり遊技盤本体２７の表面に向って飛んだり、球飛びが安定しない。そこで、従来から外レール３１の取付角度を調整しているが、この調整は熟練技術を要する面倒な作業であった。
【００３８】
このため、本実施の形態では、装着片７１の立上り角度を調整することにより外レール３１の角度調整を可能としている（図１１参照）。また、角度調整には、専用の治具７９を用意している。この治具７９は、先端に装着片７１に挟着した外レール３１の止着部３１２が嵌入可能な溝部７９１を有するもので、この治具７９を梃子として利用して僅かな力で装着片７１の角度を変え、外レール３１の取付角度を調整するものである。
【００３９】
外レール３１の取付角度が正確に調整されると、打球が通路の中央を通り、ガラスＧに衝突したり、遊技盤面に衝突することがなく、球飛びが安定する。
【００４０】
外レール３１の先端、換言すると内レール３２との変換点には跳ね返りゴム４５を位置させる。跳ね返りゴム４５は、外レール３１に沿って飛入する打球を遊技部２１へ跳ね返すもので、弾性を有するゴム質からなる。この跳ね返りゴム４５は、中央に装着孔４５１を有し、この孔４５１に第１飾りベース部材４から立上げた装着柱４５２を嵌入させると共に、前面側からこの装着柱４５２に向けてネジ止めする。尚、上記装着柱４５２には回り止めのリブ４５３が設けてある。
【００４１】
上記跳ね返りゴム４５は、外レール３１と内レール３２とを分ける部分である。上記外レール部分は球が接触して通過し、球は発射勢を有している。このため、外レール部分は耐摩耗性が必要である。一方、内レール部分になると、球は流下勢のみとなるので、球が接触しても摩耗するようなことはない。従って、合成樹脂で成形しても耐久性が劣ることがない。また、遊技部２１の側方部分には、通常、サイドランプを配設する。従って、側方部分の内レール３２には、打球が触れることがない構造となっている。
【００４２】
内レール３２は、アウト口２２を最下位置にして上側が切れたほゞ円形に形成する。即ち、前記した内側起立片４６によって形成され、下半部分は不正遊技防止部材６によって被覆される。上記内側起立片４６に沿って適宜間隔で不正遊技防止部材６を取り付けるための取付柱４６１を設ける。
【００４３】
不正遊技防止部材６は、ガラスＧと内レール３２との間の隙間からピアノ線等を挿入して入賞球がないのに、入賞装置を誤動作させて賞球を不正に獲得されることを防止するための部材である。
【００４４】
この不正遊技防止部材６は、従来から設置されているが、帯状の別部材として取り付けているため取り扱いが面倒であった。しかも、平板状の部材に切込を入れて湾曲させながら取り付けるため、作業には熟練技術が必要であって、作業者によってバラ付が生じてしまう。また、温度変化によって収縮してしまい、ガラスＧとの間に隙間が生じて機能を果たさなくなることがあった。更に、別部材として取り付けるので、コストが高くついている。
【００４５】
そこで、本実施の形態における不正遊技防止部材６は、中央部にアウト口２２を形成する凹部６１を備えるほゞ半円形の正面図形状を有する部材である。また、この不正遊技防止部材６は、断面形状が図１３に示すように、内レール３２として機能する平板部６２と、該平板部６２の前端縁から若干後退した位置から下向きに延出する押え部６３と、該押え部６３の下端から前方へ向けて延出する支持部６４と、該支持部６４の前縁から斜め外方へ向けて延出する挿入阻止片６５とを有している。そして、上記平板部６２と押え部６３と支持部６４は、後述する押え部材６６の受溝部６７を構成する。
【００４６】
尚、この不正遊技防止部材６は、温度変化等、外部環境の影響で伸縮し難いと共に、適度な柔軟性を有する材質で形成し、例えばポリプロピレンとゴムの混合物等により形成する。
【００４７】
押え部材６６は、上記不正遊技防止部材６の受溝部６７の形状に対応して、半円弧状に形成した合成樹脂製の板状部材で、前記した第１飾りベース部材４の取付柱４６１に対応する位置には取付孔６６１が設けてある（図１２参照）。また、不正遊技防止部材６の前端縁６２１が嵌入可能な嵌入溝６６２が裏面側に形成してある（図１３参照）。
【００４８】
上記のような不正遊技防止部材６によれば、ガラスＧを閉めると図１３（Ｂ）に示すように、挿入阻止片６５がガラス面に密着してピアノ線等を挿入することができなくなる。尚、図１３（Ａ）はガラスＧを開いた状態である。
【００４９】
不正遊技防止部材６のアウト口２２に対応する位置に形成した凹部６１には、後方へ向って緩く下り傾斜する複数のリブ６１１を設け、流下する球を遊技盤本体２７に開設したアウト口２２へ誘導する。また、遊技盤本体２７のアウト口２２の周囲を飾るアウト口カバー２２１は、第１飾りベース部材４に取り付けてある。従って、遊技盤本体２７に対する部品の取付が減り、組立工程の省力化が可能である。
【００５０】
前記した外レール３１において、打球発射装置１６１で発射した打球が発射レール１６４から飛び出してファール玉樋１６５を飛び越えて外レール３１に衝突する部分の付近には、破防レール１６６を取り付けて、万が一跳ね返った球がガラスＧに衝突して当該ガラスＧが破損することを防止する。尚、この破防レール１６６は、前記した不正遊技防止部材６と同質の素材からなり、適度な弾性を有する合成樹脂製である。
【００５１】

【００６５】
第２飾りベース部材５を第１飾りベース部材４に重ね、外レール３１の側端を第２飾りベース部材５の裏面側に形成した挟着溝５５１に嵌合させた状態で、所定の位置に設けたビス孔でビス止めする。尚、このビス止めは、第１飾りベース部材４の適宜な位置に設けたビス止め部４２５に、背面側からビスを挿通し、このビスを第２飾りベース部材５のビス止めボスにねじ込んで行う。
【００６６】
上記のようにして組み立てれば、金属製の外レール３１を備える飾り部材３を一体的に構成することができる。また、この飾り部材３は、内レール３２の一部として機能する内側起立片４６を第１飾りベース部材４に備えると共に、内側垂下片５４を第２飾りベース部材５に備えている。更に、内レール３２の一部としても機能する不正遊技防止部材６が取り付けてある。
【００６７】
上記不正遊技防止部材６を取り付けるには、内レール３２を形成する内側起立片４６に不正遊技防止部材６を沿わせると共に、押え部材６６を受溝部６７に嵌合させ、所定のビス孔で取付柱４６１に向けてビス止めする。これにより内レール３２の下半部分とアウト口２２の下半部分が形成される。尚、アウト口カバー２２１を一緒に取り付ける。
【００６８】
外レール３１の取り付け角度を調整するには、前記したように調整治具７９の溝部７９１を外レール３１の基端、即ち装着片７１に挟着した外レール３１の止着部３１２に差し込んで図１１の矢印のように揺動させて行えばよい。従って、従来のようにハンマーで固定釘を叩く必要がなく、誤って周囲を破損したり怪我をすることがない。
【００６９】
尚、一般に、遊技部２１に飛入した球は、アウト口２２へ向って流下することを基本的な流れとしているので、内レール３２に球が衝接しても、遊技に悪影響が出るものではない。従って、内レール３２が分割されていても遊技に影響することがない。
【００７０】
そして、上記のようにして一体に組み立てた飾り部材３は、図１５ないし図１７に示すように、所定の位置に設けた釘孔から遊技盤本体２７に向けて釘１０１を打ち込んだり、前記したようにブッシュ１００を介在させて遊技盤本体２７の位置決め兼用取付孔２７３に嵌着して取り付けることができる。尚、図１７に示すように、第１飾りベース部材４と第２飾りベース部材５とをビス１０２によって組み付けることもできる。
【００７１】
上記のようにして組み立てた飾り部材３によれば、一体に組み立てられた飾り部材３を遊技盤本体２７の前面に取り付けるだけでよいので、生産工程において大幅な省力化とコストダウンが可能になる。また、均一で安定した製品を得ることができる。一方、外レール３１を別部材としているので、飾り部材３を形成する際の金型製作において、抜き勾配を考慮する必要がなくなり、設計が自由になる。しかも、外レール３１が常に遊技盤面に対して垂直に固定されるので、発射球の進行方向に片寄りがなくなり、球飛びが安定する。更に、外レール３１の側縁を第２飾りベース部材５の挟着溝５５１に嵌入させて、外レール３１の側縁を露出させていないので、組立作業中や清掃中に怪我をする心配がなくなる。
【００７２】
図１４は他の実施の形態を示す組立図である。この実施の形態が上記した実施の形態と異なるところは、第２飾りベース部材５を複数の部材により構成するようにしたものである。
【００７３】

【００７６】
一方、上記ランプベース５７１，５７２の背面側、即ち第１飾りベース部材４の前面側には、配線基板５７７，５７８を設ける。この配線基板５７７，５７８には、コネクタやプリント配線、或は抵抗器のチップ部品等を配設する。このようにすれば、配線基板５７７，５７８が露出することがなく、すっきりすると共に、遊技盤本体２７に密着させることができる。尚、ランプやＬＥＤ等の発光源は別途に遊技盤本体２７にランプ基板を設け、この発光源の光を、遊技盤本体２７に開設したランプ孔２７１，２７２、第１飾りベース部材４に開設した透孔４２６，４２７、配線基板５７７，５７８に開設した通孔５７７ａ，５７８ａを通してレンズ部材５７５，５７６まで導く。
【００７７】
更に、この実施の形態では、第２飾りベース部材５の左下部分及び右下部分にもレンズ部材５７９ａ，５７９ｂを設けている。従って、飾り部材３はほゞ四隅にレンズ部材５７５，５７６，５７９ａ，５７９ｂを備え、装飾効果が著しく向上している。
【００７８】
尚、図１４に示した実施の形態で、説明していない符号は、前記した実施の形態における同じ符号を付した部材と同じ機能を有しているので説明を省略する。
【００７９】
以上本発明を図面の実施形態について説明したが、本発明は上記した各実施形態に限定されるものではなく、特許請求の範囲に記載した構成を変更しない限り適宜に実施できる。
【００８０】

The first decorative base member 4 is provided with an inner standing piece 46 that functions as the inner rail 32. The inner standing piece 46 is formed at the side edge of the first empty portion 41 with a gap through which a hit ball can pass so as to partially overlap the outer rail mounting portion, that is, the outer standing piece 43. In the illustrated embodiment, the inner upright piece 46 functions directly as the inner rail 32 in the left portion of the gaming portion 21, and the lower portion is the lower portion of the inner rail 32 where the unauthorized gaming prevention member 6 described later is provided. However, when the illegal game prevention member 6 is not attached, the inner standing piece 46 functions as the inner rail 32.
[0018]
On the other hand, an inner hanging piece 54 is provided on the side facing the inner standing piece 46, that is, on the right side of the game unit 21 to function as the inner rail 32. That is, it starts in an arc from the position of the rebound rubber 45 of the front plate portion 52 provided around the second empty portion 51 of the second decorative base member 5 toward the game board surface, passes through the lower right base portion 521, It ends at the left end of the concave portion 53 which becomes the out port 22 at the lower position. In the illustrated embodiment, the portion directly functioning as the inner rail 32 is the right portion of the gaming portion 21, and the lower portion is provided with a later-described unauthorized gaming preventing member 6.
[0019]
The portion where the outer standing piece 43 and the inner standing piece 46 overlap is a passage for a ball to be shot by a player, that is, a portion serving as a ball passage 47, which is connected by a bottom plate portion 471, and has a wide entrance side. The outlet side is narrowed. In addition, the tip of the bottom plate portion 471 at the exit portion is connected to the game board surface obliquely by the inclined surface 472 so that the hit ball smoothly enters the game portion 21.
[0020]
A return ball prevention device 48 is provided at the exit portion of the hit ball, that is, at the tip of the inner standing piece 46. According to the illustrated embodiment, the return ball prevention device 48 is replaceable so that the return ball prevention piece 481 having elasticity at the tip of the inner standing piece 46, for example, a stainless steel foil piece, crosses the ball passage 47 diagonally. Install and configure. Therefore, even if the hit ball collides with the obstacle nail or the rebound rubber 45 and rebounds, when the hit ball hits the return ball prevention piece 481, the return ball prevention piece 481 closes the exit of the ball passage 47. Will not flow backwards. On the other hand, the hit ball opens the return ball prevention piece 481 and jumps into the game unit 21.
[0021]
In the return ball prevention device 48, the return ball prevention piece 481 is configured to be replaceable. That is, a thick portion 482 is formed at the tip of the inner standing piece 46, and a mounting groove 484 that is partially open to the thick portion 482 and communicates with the cylindrical base end mounting portion 483 is formed. On the other hand, a mounting post 485 that can be mounted on the base end mounting portion 483 is provided by rounding the base end of the return ball prevention piece 481. Then, the mounting column 485 is inserted into the base end mounting portion 483, and the return ball prevention piece 481 is extended above the thick portion 482 through the opening. Accordingly, when the return ball prevention piece 481 is deformed, the mounting column 485 is removed from the base end mounting portion 483, and a new return ball prevention piece 481 is inserted into the base end mounting portion 483 for replacement. do it.
[0022]
The return ball prevention device 48 may be another embodiment as shown in FIG. In this embodiment, the return ball prevention device 48 is configured by extending the illegal game prevention member 6 described later. That is, a return ball prevention piece 681 is integrally formed at the distal end of the illegal game prevention member 6 attached along the inner upright piece 46 constituting the inner rail 32, and the fitting provided at the base end portion of the return ball prevention piece 681. The illegal game prevention member 6 and the return ball prevention piece 481 are attached to the hole 682 by fitting the fitting pin 481 rising from the bottom plate portion 471 of the first decorative base member 4.
[0023]
Even with the return ball prevention device 48 having such a configuration, even if the hit ball bounces off at the game unit 21 and tries to jump into the ball passage 47, the return ball prevention piece 681 blocks the exit of the ball passage 47. Occurrence can be reliably prevented. On the other hand, the returned ball prevention piece 681 does not become a resistance against the hit ball, and the hit ball smoothly enters the game unit 21.
[0024]
The tip of the return ball prevention piece 481 and the illegal game prevention member 6 is fixed to the plate-like fitting piece 483 erected from the first decorative base member 4 as shown in FIG. 6B.

[0026]
On the left and right side edges of the first decorative base member 4, there are provided lock receivers 33 that are used when the gaming board 2 is attached to the gaming machine body. The lock receiver 33 is formed with a recessed portion 331 at a predetermined position of the first decorative base member 4 and an attachment base portion 332, and the tip of the lock piece 333 made of a metal piece and the first decorative base member are provided on the attachment base portion 332. 4 and the side edges of the second decorative base member 5 to be described later, and a mounting space 334 for receiving a mounting piece of a game board mounting device (not shown) between the lower surface of the second decorative base member 5 to be described later. (See FIG. 18). The game board mounting device is a U-shaped mounting piece pivotally attached to the game board 2 so that the side of the game board 2 is sandwiched and the game board 2 is attached. Is provided.
[0027]
The hit ball launched by the hit ball launcher 161 jumps from the launch rail 164 over the foul ball 165 to the outer rail 31 and is guided to the outer rail 31 to reach the game unit 21. As described above, the outer rail in the conventional pachinko machine is formed with a cylindrical fixing portion through which the fixing nail passes by bending the base end portion, and the fixing nail passed through the fixing portion is made of veneer plywood. It was fixed by driving into the game board itself. For this reason, the hit ball hits the outer rail that is firmly fixed, and the landing point of the hit ball has been severely worn.
[0028]
Therefore, the game board 2 according to the present invention is configured so that the impact of the hit ball can be absorbed by the outer rail 31 itself. That is, the outer rail 31 can be deformed by setting a free space around the landing point where the hit ball collides.
[0029]
Therefore, in the game board 2 according to the present invention, the notch 311 is provided near the base end of the outer rail 31 to reduce the width so that the side edge does not contact the game board surface side and the width is reduced. Thus, it is configured to be easily deformed and to absorb the shock (see FIG. 10).
[0030]
Further, in order to form a free space that becomes a relief when the outer rail 31 is deformed, the proximal end portion of the outer standing piece 43, that is, the portion where the ball launched from the ball striking device 161 collides, and the appropriate front and rear thereof A step 432 is provided by slightly retreating the range so as not to be in close contact with the outer rail 31.
[0031]
Specifically, as shown in FIG. 5, the stepped portion 432 of the outer standing piece 43 is provided at a position slightly retracted from the mounting position of the outer rail 31 so that a space P is formed on the back side of the outer rail 31. . Moreover, when fixing the base end of the outer rail 31, it fixes through the outer rail fixing metal fitting 7 mentioned later.
[0032]
At the front end portion of the outer rail 31 fixed as described above, the outer rail 31 is lifted in the range of the step portion 432 where the outer rail fixing bracket 7 and the outer standing piece 43 start. For this reason, even if the hit ball launched from the hit ball launching device 161 collides, the impact is relieved by the deformation of the outer rail 31, so that stable ball jumping is obtained. Further, since the outer rail 31 is not firmly fixed, wear of the outer rail 31 due to a ball collision is also prevented, and the durability of the outer rail 31 is improved.
[0033]
In the illustrated embodiment described above, the outer rail 31 is provided with the game board, that is, the first decoration base member 4 and the second decoration by providing the notch 311 near the base end of the outer rail 31 to reduce the width. Although it is configured not to contact the base member 5, the outer rail 31 is formed by forming notches and grooves in the first decorative base member 4 and the second decorative base member 5 while keeping the width of the outer rail 31 as it is. The side edges may not be in contact with each other.
[0034]
Further, as described above, in the conventional game board, the base end of the outer rail 31 is directly fixed to the game board main body by the fixing nail. Therefore, skill is required for fixing, and angle adjustment is difficult, and it is difficult to obtain a stable ball flight. Therefore, in this embodiment, the base end of the outer rail 31 is fixed to the fixed substrate 72 by the outer rail fixing bracket 7 formed as a separate member.
[0035]
The outer rail fixing bracket 7 (see FIG. 9) is screwed into the base plate portion 42 provided on the first decorative base member 4 functioning as the fixed substrate 72, in the illustrated embodiment, on the bottom plate portion 471 of the ball passage 47 from the back side. A mounting piece 71 for mounting a fastening portion 312 provided at the tip of the outer rail 31 is provided. The mounting piece 71 is formed by cutting and raising the mounting substrate 74, and has a fitting hole 75. The mounting board 74 is provided with mounting holes 741 and positioning holes 742 for passing mounting screws. In addition, a bending locking piece 76 that is bent so as to wind the lower edge portion of the base plate portion 42 of the first decorative base member 4 is provided on a part of the lower edge of the mounting substrate 74, and the game board 2 is A locking ring (not shown) of a locking metal fitting used when placing on the board mounting table 16 is locked. Further, at the lower edge corner of the mounting board 74, when the game board 2 is installed on the game board mounting table 16, a rising and closing piece 77 is provided so as to close a gap generated between the base end of the launch rail 164, A protective cap 78 is put on the closing piece 77 so as not to be injured.
[0036]
A fastening portion 312 is formed at the base end of the outer rail 31 (see FIG. 2). The fastening portion 312 is formed by folding back the base end of the outer rail 31, and fixes the base end of the outer rail 31 by sandwiching the mounting piece 71 of the outer rail fixing bracket 7. . A dowel 313 is provided in the fastening portion 312 and the dowel 313 is fitted into the fitting hole 75 of the mounting piece 71 for positioning and retaining (see FIGS. 9 and 10).
[0037]
If the outer rail 31 does not stand up at a predetermined angle, that is, at a right angle with respect to the game board main body 27, the hit ball flies in the direction of the glass G or flies toward the surface of the game board main body 27, and the ball jump is not stable. Therefore, conventionally, the mounting angle of the outer rail 31 is adjusted, but this adjustment is a troublesome work requiring skill.
[0038]
For this reason, in this embodiment, the angle of the outer rail 31 can be adjusted by adjusting the rising angle of the mounting piece 71 (see FIG. 11). A dedicated jig 79 is prepared for angle adjustment. This jig 79 has a groove 791 into which the fastening portion 312 of the outer rail 31 sandwiched between the mounting pieces 71 can be fitted at the tip, and the mounting pieces can be applied with a slight force using this jig 79 as an insulator. The angle of 71 is changed and the mounting angle of the outer rail 31 is adjusted.
[0039]
When the mounting angle of the outer rail 31 is adjusted accurately, the hit ball passes through the center of the passage, and does not collide with the glass G or the game board surface, so that the ball jump is stabilized.
[0040]
The rebound rubber 45 is positioned at the tip of the outer rail 31, in other words, at the conversion point with the inner rail 32. The rebound rubber 45 rebounds the hit ball that jumps along the outer rail 31 to the game unit 21 and is made of rubber having elasticity. The rebound rubber 45 has a mounting hole 451 in the center, and a mounting column 452 raised from the first decorative base member 4 is fitted into the hole 451 and is screwed toward the mounting column 452 from the front side. . The mounting column 452 is provided with a detent rib 453.
[0041]
The rebound rubber 45 is a part that separates the outer rail 31 and the inner rail 32. The ball passes through the outer rail portion, and the ball has a firing force. For this reason, the outer rail portion needs to have wear resistance. On the other hand, in the inner rail portion, since the ball is only in the downward direction, it does not wear even if the ball contacts. Therefore, durability is not inferior even if it molds with a synthetic resin. In addition, side lamps are usually provided on the side portions of the gaming unit 21. Therefore, the inner rail 32 in the side portion is structured not to touch the hit ball.
[0042]
The inner rail 32 is formed in a generally circular shape with the upper side cut with the out port 22 at the lowest position. That is, it is formed by the inner standing piece 46 described above, and the lower half portion is covered by the illegal game preventing member 6. A mounting post 461 for mounting the illegal game preventing member 6 is provided along the inner upright piece 46 at appropriate intervals.

The illegal game prevention member 6 prevents a winning ball from being illegally acquired by operating the winning device erroneously when a piano wire or the like is inserted through a gap between the glass G and the inner rail 32 and there is no winning ball. It is a member for doing.
[0044]
Although this illegal game prevention member 6 has been conventionally installed, it is troublesome to handle because it is attached as a separate belt-like member. Moreover, since the flat plate-shaped member is attached while being cut and curved, skilled work is required for the work, and variations occur by the operator. Moreover, it contracted by the temperature change, and a gap was formed between the glass G and the function could not be performed. Furthermore, since it is attached as a separate member, the cost is high.
[0045]
Therefore, the illegal game preventing member 6 in the present embodiment is a member having a substantially semicircular front view shape including a concave portion 61 that forms the out port 22 at the center. Further, as shown in FIG. 13, the unauthorized game preventing member 6 includes a flat plate portion 62 that functions as the inner rail 32 and a presser that extends downward from a position slightly retracted from the front edge of the flat plate portion 62.
