【発明の属する技術分野】
本発明は、ベース部材と開閉部材との間に配設されて、ベース部材と開閉部材とを相対的に揺動開閉自在に接続するヒンジ機構に関する。
【０００２】
【従来の技術】
上記のようなヒンジ機構は遊技機に多用されており、その一例として、パチンコ機における外枠と前枠との間に配設されるヒンジ機構があげられる。パチンコ機のヒンジ機構は、外郭方形状の開口を有する外枠とこの開口面域に合わせた開閉搭載用の前枠との互いの正面左側上下に配設された上下一対のヒンジ機構からなる。
【０００３】
上下のヒンジ機構はそれぞれ、図２０に示すように、水平に配設された第１板状部５０１に軸支持孔５０２が形成された第１ヒンジ部材５００と、水平に配設された第２板状部５０６から上方に突出する支軸５０７が固設された第２ヒンジ部材５０５とから構成される。このような構成の上下一対のヒンジ機構において、軸支持孔５０２内に支軸５０７を嵌入させて第１および第２ヒンジ部材５００，５０５を水平に相対回動自在に接続させることにより、外枠に対して前枠を揺動開閉および着脱可能に支持するように構成している。
【０００４】
ところが、上記のような従来のヒンジ機構では、外枠に対して前枠を装着しようとするときに、上下両方のヒンジ機構の軸支持孔５０２と支軸５０７とをともに位置合わせして（軸心を一致させて）係合させなければならず、作業が容易でないという問題があった。特に、遊技施設内での装着にあっては、外枠が遊技島に固定されて移動不能であるとともに、前枠には遊技盤や裏セット盤、制御装置等が組み込まれて相当な重量（例えば、１５〜２０kg）を有しており、さらにヒンジ機構が重心位置と離れた側方に位置しているため、上下２カ所の位置決めを行う装着作業が極めて困難であるという問題があった。
【０００５】
このような問題に鑑みて、例えば、図２１に示すように、第１ヒンジ部材５００′の板状部５０１に外側面から軸支持孔５０２に繋がる導入開口５０３を形成し、第２ヒンジ部材５０５′の支軸５０７の左右を平面状にカットして平面部５０７ａ，５０７ａを形成し、支軸５０７の左右平面部５０７ａ，５０７ａの幅が導入開口５０３の幅より僅かに狭くなるように構成することが知られている。
【０００６】
この構成では、支軸５０７の左右平面部５０７ａ，５０７ａを導入開口５０３を通過させることにより支軸５０７を側方から軸支持孔５０２内に挿入させることができ、この状態で第１および第２ヒンジ部材５００′，５０５′を水平に相対回動させれば、左右平面部５０７ａ，５０７ａが軸支持孔５０２内に回動自在に保持される。このように構成すれば、軸支持孔５０２と支軸５０７とを上下に位置合わせすることなく支軸５０７を横方向に移動させて軸支持孔５０２内に嵌入させることができるため、外枠に前枠を取り付ける作業が簡単となる。

【０００８】
【発明が解決しようとする課題】
しかしながら、この構成の場合は、軸支持孔５０２の導入開口５０３と支軸５０７の左右平面部５０７ａ，５０７ａとが対向する位置まで前枠を揺動させると支軸５０７が軸支持孔５０２から外れ出て、前枠が外れるという問題がある。さらに、支軸５０７の係合（嵌入）方向が特定されるため、遊技島の端部等パチンコ機の設置場所によっては、島飾り等と干渉して外枠に前枠を取り付ける作業が大変困難になるという問題もある。
【０００９】
本発明は、このような問題に鑑みて成されたものであり、外枠等のベース部材に対して前枠等の開閉部材を左右どちら側からでも容易に装着させることができるとともに、一旦装着した後は、その揺動位置に拘わらず開閉部材をベース部材から外れることなくしっかりと保持することができるような構成の遊技機のヒンジ機構を提供することを目的とする。
【００１０】
【課題を解決するための手段】
このような目的達成のため、本発明に係る遊技機のヒンジ機構（例えば、実施形態における枠上部ヒンジ機構１００）は、遊技機の側部上下に配設されて開閉部材（例えば、実施形態における前枠２）をベース部材（例えば、実施形態における外枠１）に対して揺動開閉自在にヒンジ接続させる上下一対のヒンジ機構における一方のヒンジ機構であって、開閉部材に固設された軸部を有する第１ヒンジ部材（例えば、実施形態における枠上部揺動金具１１０）と、ベース部材に固設され、前方へ水平に突出する第１板状部と、第１板状部の前端部から下方へ段差状に折り曲げられて前方へ水平に突出する第２板状部とを有し、第２板状部に軸部と係合する軸孔とこの軸孔に繋がって後方に延びたガイド孔とが形成された第２ヒンジ部材（例えば、実施形態における枠上部固定金具１２０）と、第１板状部の下方に設けられ、前端から左右後方にそれぞれ延びて形成された左右一対のガイド部を有し、ガイド部に沿って軸部を前方に移動させると軸部がガイド孔へ導かれるように構成されたガイド部材と、第２板状部に設けられ、軸部が第２板状部の後方からガイド孔を通過して軸孔と係合した状態で、軸部のガイド孔への移動を規制するように軸部と係合可能な軸係合部材とを備え、ガイド部材は、左側のガイド部に沿って軸部を前方に移動させても軸部がガイド孔へ導かれるとともに、右側のガイド部に沿って軸部を前方に移動させても軸部がガイド孔へ導かれるように構成される。
【００１１】
このような構成の遊技機のヒンジ機構によれば、軸部を第２板状部の後方からガイド孔に通過させて軸孔と係合させ、この状態で軸係合部材を軸部と係合させて軸部のガイド孔への移動を規制することで、第１ヒンジ部材と第２ヒンジ部材とのヒンジ接続が行われるため、ベース部材に対して開閉部材を容易に装着させることができるとともに、一旦装着した後は、その揺動位置に拘わらず開閉部材をベース部材から外れることなくしっかりと保持することができる。また、ガイド部材により、軸部を第２ヒンジ部材の左右どちら側からでも軸孔と係合させることができるため、遊技機の設置場所等を考慮した作業性に応じて、ベース部材に対して開閉部材を左右どちら側からでも容易に装着させることができる。
【００１２】
【発明の実施の形態】
以下、本発明の好ましい実施形態について図面を参照しながら説明する。本発明に係るヒンジ機構を備えた遊技機の代表例としてパチンコ機ＰＭを図１および図２に示しており、まず、これらの図面を参照しながらパチンコ機ＰＭの全体構成について要約説明する。ここで、図１はパチンコ機ＰＭの正面図、図２はパチンコ機ＰＭの背面図である。
【００１３】
パチンコ機ＰＭは外郭方形枠サイズに構成されて縦向きの固定保持枠をなす外枠１の開口前面に、これに合わせた方形枠サイズに構成されて開閉搭載用の前枠２が互いの正面左側上下に配設された枠上部ヒンジ機構１００および枠下部ヒンジ機構２００で揺動（横開き）開閉および着脱が可能に取り付けられ、正面右側に設けられたダブル錠と称される施錠装置４を利用して常には外枠１と係合された閉鎖状態に保持される。
【００１４】
前枠２の上部前面側には、前枠２の上部前面域に合わせた方形状のガラス扉５が正面左側に設けられた扉上部ヒンジ機構５０および中間ヒンジ機構７０を利用して揺動（横開き）開閉および着脱可能に組付けられ、正面右側の施錠装置４により前枠２の上部前面を覆う閉鎖状態に保持される。
【００１５】
前枠２の下部前面側には、前枠２の下部前面域に合わせた方形状の球皿６が正面左側に設けられた中間ヒンジ機構７０および球皿下部ヒンジ機構９０を利用して揺動（横開き）開閉および着脱可能に組付けられ、正面右側の詳細図示省略するロック機構により前枠２の下部前面を覆う閉鎖状態に保持される。球皿６の右側下部には遊技球の発射操作を行う操作ハンドル８が取り付けられている。
【００１６】
前枠２の中央部から上部にかけて方形枠状の収容枠２ａ（図１７を参照）が凹設されており、この収容枠に設けられた複数のレバーＬ１，…（図１７を参照）を利用して遊技盤１０が着脱可能にセット保持され、常には閉鎖保持されるガラス扉５の背後に位置して正面の遊技領域ＰＡを遊技者に臨ませている。
【００１７】
前枠２の裏面側には、中央に前後連通する窓口を有して前枠２よりもやや小型の方形枠状に形成された裏セット盤３０が、前枠２の裏面に設けられた複数のレバーＬ２，Ｌ２…を利用して着脱可能にセット保持される。裏セット盤３０の各部には遊技球を貯留する球貯留タンク３１、タンクレール３２、整列待機通路３３、賞球カセット３４、賞球排出通路３５などの賞球装置が装備されるとともに、裏面各部に電源基板３７や主制御基板３８等の各種回路基盤および電子部品等が取り付けられ、これらの各機器および遊技盤１０の裏面に取り付けられた画像制御基板１８が図示省略するワイヤーハーネスで接続されている。
【００１８】
球皿６に前面側が覆われた前枠２の下部領域には遊技補助盤（図示せず）と称される補助機構部が形成されており、この遊技補助盤の各部に、打球発射装置（図示せず）や、裏セット盤３０側の賞球排出通路３５と繋がり球皿６に排出できない遊技球を一時貯留する貯留カセット（図示せず）などが設けられている。
【００１９】
パチンコ機ＰＭは、前枠２、ガラス扉５および球皿６がともに閉止され施錠された状態で遊技に供され、球皿６に遊技球を貯留させて操作ハンドル８を回動操作することにより遊技が開始される。操作ハンドル８が回動操作されると、球皿６に貯留された遊技球が打球発射装置により１球ずつ遊技盤１０の遊技領域ＰＡに打ち出され、以降パチンコゲームが展開される。
【００２０】
以上のように概要構成されるパチンコ機ＰＭにあって、前述したように、枠上部ヒンジ機構１００および枠下部ヒンジ機構２００により前枠２が外枠１に揺動（横開き）開閉および着脱可能に取り付けられ、また、扉上部ヒンジ機構５０および中間ヒンジ機構７０によりガラス扉５が前枠２に揺動（横開き）開閉および着脱可能に取り付けられている。以下、これらの各ヒンジ機構について図を追加参照しながら説明する。
【００２１】
まず、図３〜図１０を参照しつつ、枠上部ヒンジ機構１００について説明する。ここで、図３は枠上部ヒンジ機構１００の分解斜視図、図４は枠上部ヒンジ機構１００の分解正面図（部分断面図）、図５は枠上部ヒンジ機構１００の分解平面図（部分断面図）、図６は枠上部ヒンジ機構１００を外枠側と前枠側とに分離した状態を示す平面図、図７は枠上部ヒンジ機構１００の側面図（部分断面図）、図８は枠上部ヒンジ機構１００の変形例を示す側面図（部分断面図）、図９は枠上部ヒンジ機構１００に構成される枠上部揺動金具１１０と枠上部固定金具１２０との連結途中を示す平面図（部分断面図）、そして図１０は枠上部揺動金具１１０と枠上部固定金具１２０との連結過程を（ａ）（ｂ）の順に時系列で表す説明図（側断面図）である。
【００２２】
枠上部ヒンジ機構１００は、図３〜図５に示すように、前枠２の左側上部に固設された枠上部揺動金具１１０と、外枠１の左側上部に固設されて枠上部揺動金具１１０とヒンジ接続される枠上部固定金具１２０と、枠上部固定金具１２０の下面側に取り付けられたガイド部材１４０と、枠上部固定金具１２０の上面側に取り付けられた飾り部材１５０と、飾り部材１５０に取り付けられた軸係合部材１６０と、軸係合部材１６０の上方を覆うキャップ部材１７０とを主体に構成される。
【００２３】
枠上部揺動金具１１０は、前枠２の裏面側に固定される揺動側基部１１１と、この揺動側基部１１１から直角に折り曲げられて前方に水平に突出する揺動側板状部１１２とを主体に構成され、所定板厚の鋼板を打ち抜きおよび曲げ形成して図示する形状に形成される。揺動側基部１１１には複数の固定孔１１１ａ，…が孔開け形成されており、リベットやネジ等の締結手段をこれら複数の固定孔１１１ａ，…に通過させて前枠２へ締結固定させることで、揺動側基部１１１すなわち枠上部揺動金具１１０が前枠２の左側上部裏面側に固設される。
【００２４】
揺動側板状部１１２の前端部近傍には、上方に突出する軸部１１３がカシメ締結により固着されており、枠上部揺動金具１１０と枠上部固定金具１２０とがヒンジ接続された状態で、軸部１１３を揺動軸として前枠２が外枠１に対して揺動するように構成される。軸部１１３の上端部には、半球形に凹んだ係合溝１１３ａが形成されており（図５および図７を参照）、軸係合部材１６０の軸係合部１６１と係合するように構成されている。
【００２５】
揺動側板状部１１２の中央部には、枠側取付軸孔１１４が孔開け形成されており、図７に示すように、扉上部ヒンジ機構５０の取付軸６１が嵌合するようになっている。揺動側板状部１１２の下面側には、図４および図５に示すように、軸ガイド溝１１５が揺動側板状部１１２の前端部から枠側取付軸孔１１４まで繋がって形成されており、取付軸６１の一端が枠側取付軸孔１１４へ導かれるようになっている。これにより、扉上部ヒンジ機構５０の取付軸６１を容易に枠側取付軸孔１１４と嵌合させることができる。なお、扉上部ヒンジ機構５０および取付軸６１については後述する。
【００２６】
揺動側板状部１１２の右方には、規制ピン取付孔１１６がネジ溝を有して形成されており、この規制ピン取付孔１１６に開放角度規制ピン１１９が取り付けられるようになっている。なお、開放角度規制ピン１１９については後述する。
【００２７】
枠上部固定金具１２０は、外枠１の左上面および左側面に固定される固定側基部１２１と、この固定側基部１２１から前方へ水平に突出する第１固定側板状部１２５と、第１固定側板状部１２５の前端部から下方へ段差状に折り曲げられて前方へ水平に突出する第２固定側板状部１３１を主体に構成され、所定板厚の鋼板を打ち抜きおよび曲げ形成して図示する形状に形成される。固定側基部１２１には複数の固定孔１２２，…が孔開け形成されており、リベットやネジ等の締結手段をこれら複数の固定孔１２２，…に通過させて外枠１へ締結固定させることで、固定側基部１２１すなわち枠上部固定金具１２０が外枠１の左上面および左側面に固設される。
【００２８】
第１固定側板状部１２５の左右には、ガイド部材１４０を取り付けるためのガイド部材取付孔１２６が孔あけ形成されており、図４に示すように、ガイド部材１４０を第１固定側板状部１２５に取り付けるための皿ネジ１４９（図６を参照）の頭部に合わせた形状となっている。
【００２９】
第２固定側板状部１３１の前端部近傍には、枠上部揺動金具１１０の軸部１１３より僅かに大きい径を有する軸孔１３２が孔開け形成されており、軸部１１３と係合するように構成されている。これにより、枠上部揺動金具１１０の軸部１１３が枠上部固定金具１２０の軸孔１３２に位置して係合することで、枠上部揺動金具１１０と枠上部固定金具１２０とがヒンジ接続され、軸部１１３を揺動軸として前枠２が外枠１に対して揺動可能になる。
【００３０】
第２固定側板状部１３１の後部には、軸孔１３２に繋がるガイド孔１３３が後方へ延びて形成されている。ガイド孔１３３は、軸孔１３２から後方に向かうにつれて幅が広がるとともに、第２固定側板状部１３１の後端部と第１固定側板状部１２５の前端部とに繋がる壁部１３５まで延びて形成され、枠上部揺動金具１１０の軸部１１３を第２固定側板状部１３１の後方（壁部１３５と外枠１との間隙部）からガイド孔１３３に通過させると、軸部１１３が軸孔１３２へ達するようになっている。
【００３１】
第２固定側板状部１３１の左右には、飾り部材１５０を取り付けるための飾り部材取付孔１３４，１３４が孔開け形成されおり、図４に示すように、飾り部材１５０を第２固定側板状部１３１に取り付けるための皿ネジ（図示せず）の頭部に合わせた形状となっている。
【００３２】
なお、図６に示すように、枠上部固定金具１２０が固設される外枠１の左上部下面側には切り欠き部１３９が形成されており、枠上部揺動金具１１０と枠上部固定金具１２０とを枠上部固定金具１２０の右側からヒンジ接続させるときに、枠上部揺動金具１１０が外枠１と干渉しないようになっている。
【００３３】
ガイド部材１４０は、ポリカーボネート（ＰＣ）やＡＢＳ樹脂等の樹脂材料を用いて射出成形等の成形手段により図示する形状に一体的に形成される。ガイド部材１４０の左右には、ガイド部材１４０を第１固定側板状部１２５に取り付けるためのガイド部材取付部１４１，１４１が取付孔１４１ａ，１４１ａを有して形成されており、皿ネジ１４９を第１固定側板状部１２５の上方からガイド部材取付孔１２６に通過させて、ガイド部材取付部１４１，１４１にそれぞれネジ固定することで、ガイド部材１４０が第１固定側板状部１２５の下面側に取り付けられて、第２固定側板状部１３１と外枠１との間に位置するようになっている。
【００３４】
ガイド部材１４０の前側部には、左右一対の左ガイド部１４２および右ガイド部１４３がガイド部材１４０の前端から左右後方にそれぞれ延びて形成されており、左右のガイド部１４２，１４３に沿って枠上部揺動金具１１０の軸部１１３を前方に移動させたときに、軸部１１３が第２固定側板状部１３１のガイド孔１３３へ導かれるように構成されている。すなわち、図９に示すように、左右のガイド部１４２，１４３は、左ガイド部１４２に沿って軸部１１３を前方に移動させても軸部１１３がガイド孔１３３へ導かれるとともに、右ガイド部１４３に沿って軸部１１３を前方に移動させても軸部１１３がガイド孔１３３へ導かれるようになっている。
【００３５】
これにより、図９に示すように、枠上部揺動金具１１０の軸部１１３を枠上部固定金具１２０の左右どちら側からでも枠上部固定金具１２０の軸孔１３２と係合させることができるため、パチンコ機ＰＭの設置場所等を考慮した作業性に応じて、外枠１に対して前枠２を左右どちら側からでも容易に装着させることができる。
【００３６】
飾り部材１５０は、ポリカーボネート（ＰＣ）やポリアセタール（ＰＯＭ）等の硬質樹脂材料を用いて射出成形等の成形手段により箱状に一体的に形成され、図７に示すように、枠上部固定金具１２０における第２固定側板状部１３１の上方を覆うように構成される。これにより、枠上部揺動金具１１０の軸部１１３や、枠上部固定金具１２０の軸孔１３２およびガイド孔１３３が外部から見て飾り部材１５０に覆われた状態となり、パチンコ機ＰＭの美感が向上するとともに、軸部１１３等に対する不正行為の抑止が期待できる。
【００３７】
飾り部材１５０の左右には、飾り部材取付部１５１，１５１が取付孔１５１ａ，１５１ａを有して形成されており、皿ネジ（図示せず）を第２固定側板状部１３１の下方から第２固定側板状部１３１の飾り部材取付孔１３４に通過させて、飾り部材取付部１５１，１５１にそれぞれネジ固定することで、飾り部材１５０が第２固定側板状部１３１の上面側に取り付けられるようになっている。
【００３８】
飾り部材１５０の後側部には、逃げ孔部１５２が壁部１３５におけるガイド孔１３３の形状に合わせて形成されており、枠上部揺動金具１１０の軸部１１３が通過するように構成されている。飾り部材１５０の上部中央には、軸係合部材取付孔１５３がネジ溝（図示せず）を有して形成されており、軸係合部材１６０が取り付けられるようになっている。なお、軸係合部材取付孔１５３の深さは、軸係合部材１６０の軸係合部１６１が軸部１１３の係合溝１１３ａと係合した状態で、軸係合部材１６０の頭部が軸係合部材取付孔１５３の内部に位置する深さとなっている。
【００３９】
軸係合部材１６０は、金属製の丸棒からネジ形状に切り出し成形され、飾り部材１５０の軸係合部材取付孔１５３にネジ回転可能に取り付けられる（すなわち、軸係合部材１６０が飾り部材１５０とともに第２固定側板状部１３１に取り付けられる）。軸係合部材１６０の下端部には、枠上部揺動金具１１０の軸部１１３に形成された係合溝１１３ａと係合可能な軸係合部１６１が形成されている。
【００４０】
軸係合部１６１は、係合溝１１３ａの形状に合わせて半球形状に下方へ突出して形成され、図７に示すように、軸部１１３が枠上部固定金具１２０の軸孔１３２に位置するときに軸係合部材１６０を下方へ移動するようにネジ回転させると、軸係合部１６１が下方へ移動して係合溝１１３ａと係合し、軸部１１３の後方への移動、すなわち、軸部１１３の枠上部固定金具１２０におけるガイド孔１３３への移動を規制して、軸部１１３の側方（前後左右）にかかる荷重を受け止めるように構成される。
【００４１】
これにより、枠上部揺動金具１１０の軸部１１３が枠上部固定金具１２０の軸孔１３２と係合した状態で、軸部１１３の係合溝１１３ａと係合した軸係合部１６１により軸部１１３のガイド孔１３３への移動が規制されるため、枠上部揺動金具１１０の軸部１１３を枠上部固定金具１２０の軸孔１３２と係合させて、一旦前枠２を外枠１に揺動開閉自在に装着した後は、その揺動位置に拘わらず前枠２を外枠１から外れることなくしっかりと保持することができる。
【００４２】
また、軸係合部１６１および係合溝１１３ａが半球形状に形成されているため、軸部１１３を中心軸とした前枠２の揺動を円滑に行うことができる。さらに、軸係合部１６１と係合する係合溝１１３ａが軸部１１３の上端部に形成されているため、軸部１１３が軸孔１３２と係合した状態で軸係合部１６１が係合溝１１３ａと係合すると、軸部１１３、すなわち前枠２の外枠１に対する上動が規制され、前枠２を無理に上動させて枠下部ヒンジ機構２００に構成される枠下部揺動金具２２０と枠下部固定金具２１０とを不正に分離し、前枠２が外枠１から不正に外されることを防止することができる。
【００４３】
なお、本実施形態において、軸係合部材１６０の軸係合部１６１および軸部１１３の係合溝１１３ａが半球形状に形成されているが、これに限られるものではない、例えば、図８に示すように、軸係合部材１８２の軸係合部１８３を円柱状に形成するとともに、軸部１８１の係合溝１８１ａを軸係合部１８３の径よりも僅かに大きい軸係合部１８３と係合可能な筒穴状に形成するようにしてもよい。このようにすれば、軸係合部１６１および係合溝１１３ａが半球形状に形成された場合と同様の効果を得ることができる。
【００４４】
軸係合部材１６０の上端部には、ドライバ等の工具と係合可能な十字溝１６２が形成されており、ドライバ等の工具を十字溝１６２に係合させて回転させることで、軸係合部材１６０を回転させることができるようになっている。これにより、ドライバ等の工具を用いなければ軸係合部材１６０を回転させることが困難であるため、軸係合部１６１と係合溝１１３ａとの係合状態が容易に解除されることを防止することができる。なお、十字溝１６２に限らず、六角穴等の各種工具と係合可能な溝（穴）であればよい。
【００４５】
キャップ部材１７０は、塩化ビニル樹脂やアクリル樹脂等の樹脂材料を用いて射出成形等の成形手段により円い蓋状に一体的に形成され、図７および図１１に示すように、軸係合部材１６０の軸係合部１６１が軸部１１３の係合溝１１３ａと係合した状態で、飾り部材１５０の軸係合部材取付孔１５３に圧入取付されて軸係合部材１６０の上方を覆うように構成される。
【００４６】
これにより、軸係合部材１６０の軸係合部１６１と軸部１１３の係合溝１１３ａとの係合状態を解除するには、キャップ部材１７０を軸係合部材取付孔１５３から取り外す必要があるが、キャップ部材１７０は軸係合部材取付孔１５３に圧入取付されているため、キャップ部材１７０を変形させるようにして軸係合部材取付孔１５３から取り外す必要がある。このとき、塩化ビニル樹脂やアクリル樹脂を用いたキャップ部材１７０では、シワやひび割れといったキャップ部材１７０の取り外し操作による操作痕が残りやすいため、例えば、キャップ部材１７０を軸係合部材取付孔１５３から取り外して軸係合部１６１と係合溝１１３ａとの係合状態を不正に解除した後、もとの状態（すなわち、キャップ部材１７０が軸係合部材取付孔１５３に取り付けられた状態）に戻したとしても、キャップ部材１７０あるいは飾り部材１５０におけるキャップ部材１７０の取付位置に操作痕が残っていることで不正行為をより早く発見することができる。
【００４７】
すなわち、キャップ部材１７０は不正操作識別手段としての機能を有しており、このキャップ部材１７０により、軸係合部材１６０の軸係合部１６１と軸部１１３の係合溝１１３ａとの係合状態が解除されたときに係合解除操作の痕跡が残るため、パチンコ機ＰＭの輸送中や設置後に行われる軸部１１３や軸孔１３２等に対する不正行為をより早く発見することができる。なお、パチンコ機ＰＭの設置後にキャップ部材の色を変える等して、遊戯施設の管理者が独自に管理するようにしてもよい。これにより、例えば、キャップ部材の色を定期的に（あるいは不定期に）変えることで、同種のキャップ部材が用意されて係合解除操作の痕跡が隠されてしまうことを回避することができるため、パチンコ機ＰＭの設置後に行われる軸部１１３や軸孔１３２等に対する不正行為をより確実に早く発見することができる。
【００４８】
なお、本実施形態において、不正操作識別手段としてキャップ部材１７０が用いられているが、これに限られるものではない。例えば、図８に示すように、軸係合部材１８２の軸係合部１８３が軸部１８１の係合溝１８１ａと係合した状態で、封印シール１８６を飾り部材１８４の上面側に貼り付けて軸係合部材取付孔１８５の上部を塞ぐようにしてもよい。また、ホットボンドやネジロック等の固着充填材を用いて軸係合部材取付孔を塞ぐようにしてもよく、塗料を用いて軸係合部材取付孔を塞ぐようにしてもよい。さらに、フェノール樹脂やメラミン樹脂等の熱硬化性樹脂を用いて軸係合部材取付孔を塞ぐようにしてもよい。
【００４９】
次に、枠下部ヒンジ機構２００について図１３を参照して説明する。ここで、図１３は、枠下部ヒンジ機構２００の分解斜視図である。枠下部ヒンジ機構２００は、外枠１の左側下部に固設された枠下部固定金具２１０と、前枠２の左側下部に固設されて枠下部固定金具２１０とヒンジ接続される枠下部揺動金具２２０とを主体に構成される。
【００５０】
枠下部固定金具２１０は、外枠１の左側下部に固定される固定側基部２１１と、この固定側基部２１１が直角に折り曲げられて前方に水平に突出する固定側板状部２１２とを主体に構成され、所定板厚の鋼板を打ち抜きおよび曲げ成形して図示する形状に形成される。固定側基部２１１には複数の固定孔２１１ａ，…が孔開け形成されており、リベットやネジ等の締結手段をこれら複数の固定孔２１１ａ，…に通過させて外枠１へ締結固定させることで、固定側基部２１１すなわち枠下部固定金具２１０が外枠１の左側下部内側に固設される。
【００５１】
固定側板状部２１２の前端部近傍には、上方に突出する支軸２１５が固着されており、枠下部固定金具２１０と枠下部揺動金具２２０とがヒンジ接続された状態で、支軸２１５を揺動軸として前枠２が外枠１に対して揺動するように構成される。支軸２１５の上端部は円錐状に形成されており、後述する軸支持孔２２５との嵌合を容易化している。なお、支軸２１５の長さは、枠上部ヒンジ機構１００における軸部１１３の長さより長いことが好ましい。このようにすれば、枠上部ヒンジ機構１００における軸部１１３と軸孔１２３との係合時に支軸２１５が軸支持孔２２５から抜けにくくなるため、枠上部ヒンジ機構１００の軸部１１３と軸孔１２３とを容易に係合させることができる。
【００５２】
枠下部揺動金具２２０は、前枠２の裏面側に固定される揺動側基部２２１と、この揺動側基部２２１から直角に折り曲げられて前方に水平に突出する揺動側板状部２２２とを主体に構成され、所定板厚の鋼板を打ち抜きおよび曲げ成形して図示する形状に形成される。揺動側基部２２１には複数の固定孔２２１ａ，…が孔開け形成されており、リベットやネジ等の締結手段をこれら複数の固定孔２２１ａ，…に通過させて前枠２へ締結固定させることで、揺動側基部２２１すなわち枠下部揺動金具２２０が前枠２の裏面側に固設される。
【００５３】
揺動側板状部２２２の前端部近傍には、枠下部固定金具２１０の支軸２１５より僅かに大きい径を有する軸支持孔２２５が孔開け形成されており、支軸２１５と嵌合するように構成されている。これにより、枠下部揺動金具２２０の軸支持孔２２５が枠下部固定金具２１０の支軸２１５と嵌合することで、枠下部揺動金具２２０と枠下部固定金具２１０とがヒンジ接続され、支軸２１５を揺動軸として前枠２が外枠１に対して揺動可能になる。
【００５４】
以上のように構成される枠上部ヒンジ機構１００および枠下部ヒンジ機構２００のヒンジ接続について説明する。外枠１と前枠２とが分離した状態から、枠上部ヒンジ機構１００および枠下部ヒンジ機構２００により前枠２を外枠１に揺動（横開き）開閉および着脱可能に取り付けるには、まず、枠下部ヒンジ機構２００において、枠下部ヒンジ機構２００に構成される枠下部揺動金具２２０と枠下部固定金具２１０とをヒンジ接続させる。
【００５５】
枠下部揺動金具２２０と枠下部固定金具２１０とをヒンジ接続させるには、まず、枠下部揺動金具２２０を接続枠下部固定金具２１０の上方に位置させて、枠下部固定金具２１０の支軸２１５に対し枠下部揺動金具２２０の軸支持孔２２５を同軸上に位置決めする。
【００５６】
そして、前枠２を下動させ、支軸２１５と軸支持孔２２５とを嵌合させることにより、固定側板状部２１２で揺動側板状部２２２が支持された状態（すなわち、前枠２が支持された状態）で枠下部揺動金具２２０と枠下部固定金具２１０とがヒンジ接続され、支軸２１５を揺動軸として前枠２が外枠１に対して揺動可能になる。なお、枠下部ヒンジ構造２００における前枠２の外枠１に対する揺動軸は、枠上部ヒンジ機構１００における前枠２の外枠１に対する揺動軸と共通になっている。
【００５７】
次に、枠上部ヒンジ機構１００において、枠上部ヒンジ機構１００に構成される枠上部揺動金具１１０と枠上部固定金具１２０とをヒンジ接続させる。枠上部揺動金具１１０と枠上部固定金具１２０とをヒンジ接続させるには、まず、前枠２を傾動させて枠上部揺動金具１１０を枠上部固定金具１２０の左または右側方から接近させ、図９および図１０（ａ）に示すように、枠上部揺動金具１１０の軸部１１３を枠上部固定金具１２０の壁部１３５と外枠１との間に位置させる。
【００５８】
続いて、軸部１１３を枠上部固定金具１２０の左側方から接近させた場合には、軸部１１３を壁部１３５と外枠１との間に位置するガイド部材１４０の左ガイド部１４２に沿って前方に移動させ、第２固定側板状部１３１におけるガイド孔１３３の後方に位置させる。一方、軸部１１３を枠上部固定金具１２０の右側方から接近させた場合には、軸部１１３をガイド部材１４０の右ガイド部１４３に沿って前方に移動させ、ガイド孔１３３の後方に位置させる。
【００５９】
これにより、軸部１１３は枠上部固定金具１２０の左右どちら側からでもガイド孔１３３に案内される。すなわち、枠上部揺動金具１１０の軸部１１３を枠上部固定金具１２０の左右どちら側からでも枠上部固定金具１２０の軸孔１３２と係合させることができるため、パチンコ機ＰＭの設置場所等を考慮した作業性に応じて、外枠１に対して前枠２をより容易に装着させることができる。
【００６０】
さらに続いて、前枠２を直立方向に傾動させると、図１０（ｂ）に示すように、軸部１１３は固定側板状部１３１（壁部１３５）の後方から飾り部材１５０の逃げ孔部１５２およびガイド孔１３３を通過して軸孔１３２に位置し、軸部１１３は軸孔１３２と係合する。
【００６１】
そして、図７に示すように、軸係合部材１６０を下方へ移動するようにネジ回転させると、軸係合部材１６０の軸係合部１６１が下方へ移動して係合溝１１３ａと係合し、軸係合部１６１により軸部１１３の後方への移動、すなわち、軸部１１３のガイド孔１３３への移動が規制されて、軸部１１３の側方（前後左右）にかかる荷重が受け止められる状態となる。
【００６２】
このようにして、軸部１１３を第２固定側板状部１３１の後方からガイド孔１３３に通過させて軸孔１３２と係合させ、この状態で軸係合部材１６０の軸係合部１６１を軸部１１３の係合溝１１３ａと係合させて軸部１１３のガイド孔１３３への移動を規制することで、枠上部揺動金具１１０と枠上部固定金具１２０とのヒンジ接続が行われるため、外枠１に対して前枠２を容易に装着させることができるとともに、一旦装着した後は、その揺動位置に拘わらず前枠２を外枠１から外れることなくしっかりと保持することができる。
【００６３】
さらに、図７および図１１に示すように、軸係合部材１６０の軸係合部１６１が軸部１１３の係合溝１１３ａと係合した状態で、キャップ部材１７０を不正操作識別手段として飾り部材１５０の軸係合部材取付孔１５３に圧入取付し、軸係合部材取付孔１５３を塞いで軸係合部材１６０の上方を覆うようにする。これにより、軸係合部材１６０の軸係合部１６１と軸部１１３の係合溝１１３ａとの係合状態が解除されたときに係合解除操作の痕跡が残るため、パチンコ機ＰＭの輸送中や設置後に行われる軸部１１３や軸孔１３２等に対する不正行為をより早く発見することができる。
【００６４】
この結果、枠上部揺動金具１１０の軸部１１３が枠上部固定金具１２０の軸孔１３２および軸係合部材１６０の軸係合部１６１と係合して軸部１１３の側部が保持された状態で、枠上部揺動金具１１０と枠上部固定金具１２０とがヒンジ接続され、軸部１１３を揺動軸として前枠２が外枠１に対して揺動可能になる。なお、前述したように、枠上部ヒンジ機構１００における前枠２の外枠１に対する揺動軸は、枠下部ヒンジ構造２００における前枠２の外枠１に対する揺動軸と共通になっている。
【００６５】
なお、前枠２を外枠１から取り外すには、まず、枠上部ヒンジ機構１００において枠上部揺動金具１１０と枠上部固定金具１２０とを分離し、次に、枠下部ヒンジ機構２００において枠下部ヒンジ機構２００に構成される枠下部揺動金具２２０と枠下部固定金具２１０とを分離すればよい。
【００６６】
枠上部揺動金具１１０と枠上部固定金具１２０とを分離するには、まず、キャップ部材１７０を飾り部材１５０の軸係合部材取付孔１５３から取り外した後、軸係合部材１６０を上方へ移動するようにネジ回転させて軸係合部材１６０の軸係合部１６１と軸部１１３の係合溝１１３ａとの係合状態を解除し、前枠２を後方に傾動させるようにすればよい。
【００６７】
次に、扉上部ヒンジ機構５０について図１１および図１２を参照して説明する。ここで、図１１は扉上部ヒンジ機構５０の正面図（部分断面図）、図１２は扉上部ヒンジ機構５０の平面拡大図（部分断面図）である。
【００６８】
扉上部ヒンジ機構５０は、図３にも示すように、前枠２の左側上部に固設された固定金具としての枠上部揺動金具１１０と、ガラス扉５の左側上部に固設されて枠上部揺動金具１１０とヒンジ接続される扉側揺動金具５１と、枠上部揺動金具１１０と扉側揺動金具５１とをヒンジ接続するための取付軸６１と、取付軸６１を上方に向けて付勢する軸付勢バネ６２とを主体に構成される。
【００６９】
扉側揺動金具５１は、前枠２の裏面側に固定される扉側基部５２と、この扉側基部５２の上下で直角に折り曲げられて前方に水平に突出する扉側板状部５３ａ，５３ｂとを主体に構成され、所定板厚の鋼板を打ち抜きおよび曲げ形成して図示する形状に形成される。なお、詳細図示しないが、扉側揺動金具５１は、ガラス扉５の左端部裏面側に固設された補強板金５９（図１７を参照）の上端部に繋がって形成されている。
【００７０】
扉側基部５２には複数の固定孔５２ａ，…が孔開け形成されており、リベットやネジ等の締結手段をこれら複数の固定孔５２ａ，…に通過させてガラス扉５へ締結固定させることで、扉側基部５２すなわち扉側揺動金具５１がガラス扉５の左側上部裏面側に固設される。なお、扉側揺動金具５１は、補強板金５９と別体にガラス扉５の左側上部裏面側に固設されてもよい。
【００７１】
また、扉側基部５２の側部には、ピン当接部５５が扉側基部５２の側部から直角に折り曲げられて形成されており、枠上部揺動金具１１０に設けられた開放角度規制ピン１１９に当接するようになっている。なお、ピン当接部５５は、補強板金５９と一体にガラス扉５の裏面側に形成されてもよく、また、扉側揺動金具５１や補強板金５９と別体にガラス扉５の裏面側に設けられてもよい。ピン当接部５５を扉側基部５２や補強板金５９と一体に形成することにより、部品点数の削減が可能となり、パチンコ機ＰＭのコストを削減することができる。
【００７２】
扉側板状部５３ａ，５３ｂには、取付軸６１より僅かに大きい径を有する扉側軸孔５４ａ，５４ｂが孔開け形成されており、取付軸６１と嵌合可能に構成されている。
【００７３】
取付軸６１は、金属製の丸棒から切り出しおよび曲げ加工によりＬ字状に成形され、扉側板状部５３ａ，５３ｂの扉側軸孔５４ａ，５４ｂおよび枠上部揺動金具１１０の枠側取付軸孔１１４と嵌合して扉側揺動金具５１と枠上部揺動金具１１０とがヒンジ接続された状態で、取付軸６１を揺動軸としてガラス扉５が前枠２に対して揺動するように構成される。取付軸６１の一端には、面取り６１ａが形成されており、取付軸６１を扉側軸孔５４ａ，５４ｂおよび枠側取付軸孔１１４と嵌合させやすいようになっている。取付軸６１の他端には、操作部６１ｂが取付軸６１の他端で直角に折り曲げられて形成されており、作業者が取付軸６１を操作しやすいようになっている。
【００７４】
取付軸６１の中央部一端側には、リング状のバネ受け部材６３が固着されており、図１１に示すように、軸付勢バネ６２の付勢力を受け止めるとともに、上側の扉側板状部５３ａに当接して取付軸６１の上方への移動を規制するようになっている。さらに、バネ受け部材６３が上側の扉側板状部５３ａに当接すると、図１０に示すように、取付軸６１の一端が上側の扉側板状部５３ａから上方へ突出するようになっている。
【００７５】
軸付勢バネ６２は、金属線材から切断および曲げ加工により形成された圧縮コイルバネであり、図１１に示すように取付軸６１に取り付けられる。そして、軸付勢バネ６２の一端が取付軸６１に固着されたバネ受け部材６３に当接するとともに、軸付勢バネ６２の他端が下側の扉側板状部５３ｂに当接することで、軸付勢バネ６２により取付軸６１が上方に向けて付勢されるようになっている。
【００７６】
そして取付軸６１を、下側の扉側軸孔５４ｂ、軸付勢バネ６２、そして上側の扉側軸孔５４ａの順で通過嵌合させ、この状態で取付軸６１の中央部一端側にバネ受け部材６３を固着させることで、図１１に示すように、軸付勢バネ６２により取付軸６１が上方に向けて付勢され、常には取付軸６１の一端が上側の扉側板状部５３ａから上方へ突出した状態で、取付軸６１が扉側基部５２の扉側板状部５３ａ，５３ｂに上下にスライド移動可能に取り付けられる。
【００７７】
さて、枠上部ヒンジ機構１００の枠上部揺動金具１１０は、扉上部ヒンジ機構５０において、扉側揺動金具５１とヒンジ接続される固定金具としても機能している。そして、前述したように、枠上部揺動金具１１０の揺動側板状部１１２には、枠側取付軸孔１１４が孔開け形成されており、取付軸６１が嵌合するようになっている。
【００７８】
また、揺動側板状部１１２の右側には、所定開放規制角度においてガラス扉５の前枠２に対する開放揺動を規制する開放角度規制ピン１１９が取り付けられている。開放角度規制ピン１１９は、金属材料を用いて一端にネジ溝１１９ａを有する棒状に切り出し形成され、揺動側板状部１１２の下方からネジ溝１１９ａを規制ピン取付孔１１６にネジ固定することにより、図１１に示すように、揺動側板状部１１２の右側に下方に突出するように取り付けられる。
【００７９】
そして、図１１および図１２に示すように、ガラス扉５を前枠２に対して所定開放規制角度まで開放揺動させると、扉側基部５２のピン当接部５５が開放角度規制ピン１１９に当接するようになっている。これにより、前枠２に固設された枠上部揺動金具１１０にガラス扉５の前枠２に対する開放揺動を規制する開放角度規制ピン１１９が設けられるとともに、ガラス扉５に固設された扉側揺動金具５１に開放角度規制ピン１１９と当接するピン当接部５５が設けられているため、パチンコ機ＰＭに別途開放揺動規制装置を設ける必要がなく、ガラス扉５の前枠２に対する開放揺動規制を簡潔低廉に行うことができる。
【００８０】
次に、中間ヒンジ機構７０について図１４を参照して説明する。ここで、図１４は、中間ヒンジ機構７０の分解斜視図である。中間ヒンジ機構７０は、ガラス扉５の左側下部に固設された中間揺動金具７１と、前枠２の左側中央部に固設されて中間揺動金具７１とヒンジ接続される中間固定金具８１とを主体に構成される。
【００８１】
中間揺動金具７１は、前枠２の左側下部に固定される揺動側基部７２と、この揺動側基部７２が直角に折り曲げられて前方に水平に突出する揺動側板状部７３とを主体に構成され、所定板厚の鋼板を打ち抜きおよび曲げ成形して図示する形状に形成される。揺動側基部７２には複数の固定孔（図示せず）が孔開け形成されており、リベットやネジ等の締結手段をこれら複数の固定孔（図示せず）に通過させて前枠２の裏面側に固設される補強板金７９とともに前枠２へ締結固定させることで、揺動側基部７２すなわち中間揺動金具７１が前枠２の左側下部裏面側に固設される。
【００８２】
揺動側板状部７３の左端部（図１４における右端部）には、中間固定金具８１の両頭ピン８４より僅かに大きい径を有するピン孔７４が孔開け形成されており、両頭ピン８４の上側と嵌合するように構成されている。また、揺動側板状部７３の揺動側基部７２を挟んだ反対側には、侵入防止部７５が板状に形成されており、針金やセル板等の異物が遊技盤１０の表面側に入り込みにくくなっている。これにより、パチンコ機ＰＭにおける遊技盤１０等への不正行為を防止することができる。
【００８３】
中間固定金具８１は、前枠２の左側中央部に固定される固定側基部８２と、この固定側基部８２から直角に折り曲げられて前方に水平に突出する固定側板状部８３とを主体に構成され、所定板厚の鋼板を打ち抜きおよび曲げ成形して図示する形状に形成される。固定側基部８２には複数の固定孔８２ａ，…が孔開け形成されており、リベットやネジ等の締結手段をこれら複数の固定孔８２ａ，…に通過させて前枠２へ締結固定させることで、固定側基部８２すなわち中間固定金具８１が前枠２の左側中央部に固設される。
【００８４】
固定側板状部８２の前端部近傍には、上下方向に突出する両頭ピン８４が固着されており、中間揺動金具７１と中間固定金具８１とがヒンジ接続された状態で、両頭ピン８４を揺動軸としてガラス扉５が前枠２に対して揺動するように構成される。両頭ピン８４の両端部は円錐状に形成されており、ピン孔７４との嵌合を容易化している。また、上側の両頭ピン８４の基端部にはヒンジ部材受け部８５が形成されており、中間揺動金具７１を支持するようになっている。
【００８５】
以上のように構成される扉上部ヒンジ機構５０および中間ヒンジ機構７０のヒンジ接続について説明する。前枠２とガラス扉５とが分離した状態から、扉上部ヒンジ機構５０および中間ヒンジ機構７０によりガラス扉５を前枠２に揺動（横開き）開閉および着脱可能に取り付けるには、まず、中間ヒンジ機構７０において、中間ヒンジ機構７０に構成される中間揺動金具７０と中間固定金具８１とをヒンジ接続させる。
【００８６】
中間揺動金具７１と中間固定金具８１とをヒンジ接続させるには、まず、中間揺動金具７１を中間固定金具８１の上方に位置させて、中間固定金具８１の両頭ピン８４に対し中間揺動金具７１のピン孔７４を同軸上に位置決めする。
【００８７】
そして、ガラス扉５を下動させ、ピン孔７４と両頭ピン８４の上側とを嵌合させることにより、中間固定金具８１のヒンジ部材受け部８５で中間揺動金具７１が支持された状態（すなわち、ガラス扉５が支持された状態）で中間揺動金具７１と中間固定金具８１とがヒンジ接続され、両頭ピン８４を揺動軸としてガラス扉５が前枠２に対して揺動可能になる。なお、中間ヒンジ機構７０におけるガラス扉５の前枠２に対する揺動軸は、扉上部ヒンジ機構５０におけるガラス扉５の前枠２に対する揺動軸と共通になっている。
【００８８】
次に、扉上部ヒンジ機構５０において、扉上部ヒンジ機構５０に構成される扉側揺動金具５１と枠上部揺動金具１１０とをヒンジ接続させる。扉側揺動金具５１と枠上部揺動金具１１０とをヒンジ接続させるには、まず、取付軸６１を下方にスライド移動させて取付軸６１の一端を上側の扉側板状部５３ａから僅かに上方へ突出させた状態で、扉側揺動金具５１を枠上部揺動金具１１０の下方に位置させる。
【００８９】
そして、軸付勢バネ６２の付勢力により取付軸６１を上方にスライド移動させて取付軸６１の一端を枠上部揺動金具１１０の軸ガイド溝１１５に当接させ、この状態で前枠２を直立方向に傾動させると、取付軸６１の一端が軸ガイド溝１１５に導かれて枠上部揺動金具１１０の枠側取付軸孔１１４に位置し、取付軸６１が上方にスライド移動して枠側取付軸孔１１４と係合する。
【００９０】
このようにして、扉側基部５２に取り付けられた取付軸６１が枠上部揺動金具１１０の枠側取付軸孔１１４と嵌合して取付軸６１の側部が保持された状態で、扉側揺動金具５１と枠上部揺動金具１１０とがヒンジ接続され、取付軸６１を揺動軸としてガラス扉５が前枠２に対して揺動可能になる。なお、前述したように、扉上部ヒンジ機構５０におけるガラス扉５の前枠２に対する揺動軸は、中間ヒンジ機構７０におけるガラス扉５の前枠２に対する揺動軸と共通になっている。
【００９１】
なお、ガラス扉５を前枠２から取り外すには、まず、扉上部ヒンジ機構５０において扉側揺動金具５１と枠上部揺動金具１１０とを分離し、次に、中間ヒンジ機構７０において中間ヒンジ機構７０に構成される中間揺動金具７０と中間固定金具８１とを分離すればよい。扉側揺動金具５１と枠上部揺動金具１１０とを分離するには、取付軸６１を下方へスライド移動させて枠上部揺動金具１１０の枠側取付軸孔１１４との嵌合を解除し、この状態で前枠２を前方に傾動させればよい。
【００９２】
以上に説明した本実施形態によるパチンコ機ＰＭの枠上部ヒンジ機構１００によれば、軸部１１３を第２固定側板状部１３１の後方からガイド孔１３３に通過させて軸孔１３２と係合させ、この状態で軸係合部材１６０の軸係合部１６１を軸部１１３の係合溝１１３ａと係合させて軸部１１３のガイド孔１３３への移動を規制することで、枠上部揺動金具１１０と枠上部固定金具１２０とのヒンジ接続が行われるため、外枠１に対して前枠２を容易に装着させることができるとともに、一旦装着した後は、その揺動位置に拘わらず前枠２を外枠１から外れることなくしっかりと保持することができる。
【００９３】
また、軸係合部１６１および係合溝１１３ａが半球形状に形成されているため、軸部１１３を中心軸とした前枠２の揺動を円滑に行うことができる。さらに、軸係合部１６１と係合する係合溝１１３ａが軸部１１３の上端部に形成されているため、軸部１１３が軸孔１３２と係合した状態で軸係合部１６１が係合溝１１３ａと係合すると、軸部１１３、すなわち前枠２の外枠１に対する上動が規制され、前枠２を無理に上動させて枠下部ヒンジ機構２００に構成される枠下部揺動金具２２０と枠下部固定金具２１０とを不正に分離し、前枠２が外枠１から不正に外されることを防止することができる。
【００９４】
また、軸係合部材１６０の十字溝１６２により、ドライバ等の工具を用いなければ軸係合部材１６０を回転させることが困難であるため、軸係合部１６１と係合溝１１３ａとの係合状態が容易に解除されることを防止することができる。さらに、キャップ部材１７０により、軸係合部材１６０の軸係合部１６１と軸部１１３の係合溝１１３ａとの係合状態が解除されたときに係合解除操作の痕跡が残るため、パチンコ機ＰＭの輸送中や設置後に行われる軸部１１３や軸孔１３２等に対する不正行為をより早く発見することができる。
【００９５】
また、ガイド部材１４０により、枠上部揺動金具１１０の軸部１１３を枠上部固定金具１２０の左右どちら側からでも枠上部固定金具１２０の軸孔１３２と係合させることができるため、パチンコ機ＰＭの設置場所等を考慮した作業性に応じて、外枠１に対して前枠２を左右どちら側からでも容易に装着させることができる。さらに、飾り部材１５０により、枠上部揺動金具１１０の軸部１１３や、枠上部固定金具１２０の軸孔１３２およびガイド孔１３３が外部から見て飾り部材１５０に覆われた状態となり、パチンコ機ＰＭの美感が向上するとともに、軸部１１３等に対する不正行為の抑止が期待できる。
【００９６】
次に、枠上部ヒンジ機構の第二実施形態について図１５および図１６を参照して説明する。ここで、図１５は第二実施形態における枠上部ヒンジ機構３００の分解斜視図、そして図１６は枠上部ヒンジ機構３００の拡大側面図（部分断面図）である。なお、本実施形態の枠上部ヒンジ機構３００は、上述した第一実施形態における枠上部ヒンジ機構１００の装置構成のみ異なり、他の装置構成は同様であるため同一部位に同一番号を付して重複説明を省略する。
【００９７】
第二実施形態における枠上部ヒンジ機構３００は、前枠２の左側上部に固設された枠上部揺動金具３１０と、外枠１の左側上部に固設されて枠上部揺動金具３１０とヒンジ接続される枠上部固定金具３２０と、枠上部固定金具３２０の下面側に取り付けられたガイド部材３４０と、枠上部固定金具３２０の上面側に取り付けられた飾り部材３５０と、飾り部材３５０に取り付けられた軸係合部材３６０と、軸係合部材１６０の上方を覆う充填固着材３７０とを主体に構成される。
【００９８】
枠上部揺動金具３１０は、前枠２の裏面側に固定される揺動側基部（図示せず）と、この揺動側基部から直角に折り曲げられて前方に水平に突出する揺動側板状部３１２とを主体に構成され、所定板厚の鋼板を打ち抜きおよび曲げ形成して図示する形状に形成される。そして、第一実施形態における枠上部ヒンジ機構１００と同様に、リベットやネジ等の締結手段により、揺動側基部すなわち枠上部揺動金具３１０が前枠２の左側上部裏面側に固設される。
【００９９】
揺動側板状部３１２の前端部近傍には、上方に突出する軸部３１３がカシメ締結により固着されており、枠上部揺動金具３１０と枠上部固定金具３２０とがヒンジ接続された状態で、軸部３１３を揺動軸として前枠２が外枠１に対して揺動するように構成される。軸部３１３の上端部には、凸部３１３ａが半球形状に上方へ突出して形成されている。
【０１００】
なお、揺動側板状部３１２の各部には、詳細図示しないが、第一実施形態における枠上部ヒンジ機構１００と同様に、扉上部ヒンジ機構５０の取付軸６１が嵌合する枠側取付軸孔３１４や、開放角度規制ピン１１９が取り付けられる規制ピン取付孔（図示せず）等が形成されている。
【０１０１】
枠上部固定金具３２０は、第一実施形態における枠上部ヒンジ機構１００と同様に、外枠１の左上面および左側面に固定される固定側基部３２１と、この固定側基部３２１から前方へ水平に突出する第１固定側板状部３２５と、第１固定側板状部３２５の前端部から下方へ段差状に折り曲げられて前方へ水平に突出する第２固定側板状部３３１を主体に構成され、所定板厚の鋼板を打ち抜きおよび曲げ形成して図示する形状に形成される。固定側基部３２１には複数の固定孔３２２，…が孔開け形成されており、リベットやネジ等の締結手段をこれら複数の固定孔３２２，…に通過させて外枠１へ締結固定させることで、固定側基部３２１すなわち枠上部固定金具３２０が外枠１の左上面および左側面に固設される。
【０１０２】
第１固定側板状部３２５の左右には、ガイド部材３４０を取り付けるためのガイド部材取付孔３２６が孔あけ形成されており、第一実施形態における枠上部ヒンジ機構１００と同様に、ガイド部材３４０を第１固定側板状部３２５に取り付けるための皿ネジ（図示せず）の頭部に合わせた形状となっている。
【０１０３】
第２固定側板状部３３１の前端部近傍には、枠上部揺動金具３１０の軸部３１３より僅かに大きい径を有する軸孔３３２が孔開け形成されており、軸部３１３と係合するように構成されている。これにより、枠上部揺動金具３１０の軸部３１３が枠上部固定金具３２０の軸孔３３２に位置して係合することで、枠上部揺動金具３１０と枠上部固定金具３２０とがヒンジ接続され、軸部３１３を揺動軸として前枠２が外枠１に対して揺動可能になる。
【０１０４】
第２固定側板状部３３１の後部には、軸孔３３２に繋がるガイド孔３３３が後方へ延びて形成されている。ガイド孔３３３は、軸孔３３２から後方に向かうにつれて幅が広がるとともに、第２固定側板状部３３１の後端部と第１固定側板状部３２５の前端部とに繋がる壁部３３５まで延びて形成され、枠上部揺動金具３１０の軸部３１３を第２固定側板状部３３１の後方（壁部３３５と外枠１との間隙部）からガイド孔３３３に通過させると、軸部３１３が軸孔３３２へ達するようになっている。
【０１０５】
第２固定側板状部３３１の左右には、飾り部材３５０を取り付けるための飾り部材取付孔３３４，３３４が孔開け形成されおり、第一実施形態における枠上部ヒンジ機構１００と同様に、飾り部材３５０を第２固定側板状部３３１に取り付けるための皿ネジ（図示せず）の頭部に合わせた形状となっている。
【０１０６】
ガイド部材３４０は、第一実施形態における枠上部ヒンジ機構１００と同様に、ポリカーボネート（ＰＣ）やＡＢＳ樹脂等の樹脂材料を用いて射出成形等の成形手段により図示する形状に一体的に形成される。ガイド部材３４０の左右には、ガイド部材３４０を第１固定側板状部３２５に取り付けるためのガイド部材取付部３４１，３４１が取付孔３４１ａ，３４１ａを有して形成されており、皿ネジ（図示せず）を第１固定側板状部３２５の上方からガイド部材取付孔３２６に通過させて、ガイド部材取付部３４１，３４１にそれぞれネジ固定することで、ガイド部材３４０が第１固定側板状部３２５の下面側に取り付けられて、第２固定側板状部３３１と外枠１との間に位置するようになっている。
【０１０７】
ガイド部材３４０の前側部には、左右一対の左ガイド部３４２および右ガイド部３４３がガイド部材３４０の前端から左右後方にそれぞれ延びて形成されており、左右のガイド部３４２，３４３に沿って枠上部揺動金具３１０の軸部３１３を前方に移動させたときに、軸部３１３が第２固定側板状部３３１のガイド孔３３３へ導かれるように構成されている。すなわち、左右のガイド部３４２，３４３は、左ガイド部３４２に沿って軸部３１３を前方に移動させても軸部３１３がガイド孔３３３へ導かれるとともに、右ガイド部３４３に沿って軸部３１３を前方に移動させても軸部３１３がガイド孔３３３へ導かれるようになっている。
【０１０８】
これにより、枠上部揺動金具３１０の軸部３１３を枠上部固定金具３２０の左右どちら側からでも枠上部固定金具３２０の軸孔３３２と係合させることができるため、パチンコ機ＰＭの設置場所等を考慮した作業性に応じて、外枠１に対して前枠２を左右どちら側からでも容易に装着させることができる。
【０１０９】
飾り部材３５０は、第一実施形態における枠上部ヒンジ機構１００と同様に、ポリカーボネート（ＰＣ）やポリアセタール（ＰＯＭ）等の硬質樹脂材料を用いて射出成形等の成形手段により箱状に一体的に形成され、図１６に示すように、枠上部固定金具３２０における第２固定側板状部３３１の上方を覆うように構成される。これにより、枠上部揺動金具３１０の軸部３１３や、枠上部固定金具３２０の軸孔３３２およびガイド孔３３３が外部から見て飾り部材３５０に覆われた状態となり、パチンコ機ＰＭの美感が向上するとともに、軸部３１３等に対する不正行為の抑止が期待できる。
【０１１０】
飾り部材３５０の左右には、飾り部材取付部３５１が取付孔３５１ａを有して形成されており、皿ネジ（図示せず）を第２固定側板状部３３１の下方から第２固定側板状部３３１の飾り部材取付孔３３４に通過させて、飾り部材取付部３５１にそれぞれネジ固定することで、飾り部材３５０が第２固定側板状部３３１の上面側に取り付けられるようになっている。
【０１１１】
飾り部材３５０の後側部には、逃げ孔部３５２が壁部３３５におけるガイド孔３３３の形状に合わせて形成されており、枠上部揺動金具３１０の軸部３１３が通過するように構成されている。飾り部材３５０の上部中央には、軸係合部材取付孔３５３がネジ溝（図示せず）を有して形成されており、軸係合部材３６０が下側から取り付けられるようになっている。なお、軸係合部材取付孔３５３の深さは、軸係合部材３６０の軸係合部３６１が軸部３１３の係合凸部３１３ａと係合した状態で、軸係合部材３６０の頭部が軸係合部材取付孔３５３の内部に位置する深さとなっている。
【０１１２】
軸係合部材３６０は、金属製の丸棒からネジ形状に切り出し成形され、飾り部材３５０の軸係合部材取付孔３５３に下側からネジ回転可能に取り付けられる（すなわち、軸係合部材３６０が飾り部材３５０とともに第２固定側板状部３３１に取り付けられる）。軸係合部材３６０の下端部には、枠上部揺動金具３１０における軸部３１３の上端部と係合可能な軸係合部３６１が形成されている。
【０１１３】
軸係合部３６１は、軸部３１３の径よりも僅かに大きい内径を有する筒蓋状に形成され、図１６に示すように、軸部３１３が枠上部固定金具３２０の軸孔３３２に位置するときに軸係合部材３６０を下方へ移動するようにネジ回転させると、軸係合部３６１が下方へ移動して軸係合部３６１の周部３６１ａが軸部３１３の上端部と係合するとともに、軸係合部３６１の底部３６１ｂが軸部３１３の凸部３１３ａに当接し、軸部３１３の後方への移動、すなわち、軸部３１３の枠上部固定金具３２０におけるガイド孔３３３への移動を規制して、軸部３１３の側方（前後左右）にかかる荷重を受け止めるように構成される。
【０１１４】
これにより、枠上部揺動金具３１０の軸部３１３が枠上部固定金具３２０の軸孔３３２と係合した状態で、軸部３１３の上端部と係合した軸係合部３６１（周部３６１ａ）により軸部３１３のガイド孔３３３への移動が規制されるため、枠上部揺動金具３１０の軸部３１３を枠上部固定金具３２０の軸孔３３２と係合させて、一旦前枠２を外枠１に揺動開閉自在に装着した後は、その揺動位置に拘わらず前枠２を外枠１から外れることなくしっかりと保持することができる。
【０１１５】
また、軸係合部３６１の周部３６１ａが軸部３１３の上端部と係合するときに、軸部３１３の上端部から上方へ突出して形成された半球形状の凸部３１３ａが軸係合部３６１の底部３６１ｂに当接するため、軸部３１３を中心軸とした前枠２の揺動を円滑に行うことができる。さらに、軸部３１３の凸部３１３ａが軸係合部３６１の底部３６１ｂに当接するため、軸部３１３、すなわち前枠２の外枠１に対する上動が規制され、前枠２を無理に上動させて枠下部ヒンジ機構２００に構成される枠下部揺動金具２２０と枠下部固定金具２１０とを不正に分離し、前枠２が外枠１から不正に外されることを防止することができる。
【０１１６】
軸係合部材３６０の上端部には、ドライバ等の工具と係合可能な十字溝３６２が形成されており、ドライバ等の工具を十字溝３６２に係合させて回転させることで、軸係合部材３６０を回転させることができるようになっている。これにより、ドライバ等の工具を用いなければ軸係合部材３６０を回転させることが困難であるため、軸係合部３６１と軸部３１３の上端部との係合状態が容易に解除されることを防止することができる。なお、十字溝３６２に限らず、六角穴等の各種工具と係合可能な溝（穴）であればよい。
【０１１７】
充填固着材３７０には、ホットメルトやネジロック（液状ボンド）等が用いられ、図１６に示すように、軸係合部材３６０の軸係合部３６１が軸部３１３の上端部と係合した状態で、飾り部材３５０の軸係合部材取付孔３５３を塞いで（軸係合部材取付孔３５３に充填固着材３７０を充填して）軸係合部材３６０の上方を覆うように用いられる。
【０１１８】
これにより、軸係合部材３６０の軸係合部３６１と軸部３１３の上端部との係合状態を解除するには、充填固着材３７０を軸係合部材取付孔３５３から除去する必要があるが、充填固着材３７０を軸係合部材取付孔３５３から除去するのは困難であるだけでなく、一旦除去すると、もとの状態に戻すのが困難なため、例えば、充填固着材３７０を軸係合部材取付孔３５３から除去して軸係合部１６１と係合溝１１３ａとの係合状態を不正に解除した後、もとの状態に戻したとしても、充填固着材３７０の除去操作痕が残るため、不正行為をより早く発見することができる。
【０１１９】
すなわち、充填固着材３７０は不正操作識別手段としての機能を有しており、この充填固着材３７０により、軸係合部材３６０の軸係合部３６１と軸部１１３の上端部との係合状態が解除されたときに係合解除操作の痕跡が残るため、パチンコ機ＰＭの輸送中や設置後に行われる軸部３１３や軸孔３３２等に対する不正行為をより早く発見することができる。
【０１２０】
なお、本実施形態において、不正操作識別手段として充填固着材３７０が用いられているが、これに限られるものではなく、例えば、軸係合部材の軸係合部が軸部の上端部と係合した状態で、封印シールを飾り部材の上面側に貼り付けて軸係合部材取付孔の上部を塞ぐようにしてもよい。また、塗料を用いて軸係合部材取付孔を塞ぐようにしてもよく、フェノール樹脂やメラミン樹脂等の熱硬化性樹脂を用いて軸係合部材取付孔を塞ぐようにしてもよい。さらに、塩化ビニル樹脂やアクリル樹脂等を用いて成形された操作痕の残りやすいキャップ部材を軸係合部材取付孔に圧入して塞ぐようにしてもよい。
【０１２１】
このように構成される枠上部ヒンジ機構３００において、枠上部揺動金具３１０と枠上部固定金具３２０とをヒンジ接続させるには、まず、前枠２を傾動させて枠上部揺動金具３１０を枠上部固定金具３２０の左または右側方から接近させ、枠上部揺動金具３１０の軸部３１３を枠上部固定金具３２０の壁部３３５と外枠１との間に位置させる。
【０１２２】
続いて、軸部３１３を枠上部固定金具３２０の左側方から接近させた場合には、軸部３１３を壁部３３５と外枠１との間に位置するガイド部材３４０の左ガイド部３４２に沿って前方に移動させ、第２固定側板状部３３１におけるガイド孔３３３の後方に位置させる。一方、軸部３１３を枠上部固定金具３２０の右側方から接近させた場合には、軸部３１３をガイド部材３４０の右ガイド部３４３に沿って前方に移動させ、ガイド孔３３３の後方に位置させる。
【０１２３】
これにより、軸部３１３は枠上部固定金具３２０の左右どちら側からでもガイド孔３３３に案内される。すなわち、枠上部揺動金具３１０の軸部３１３を枠上部固定金具３２０の左右どちら側からでも枠上部固定金具３２０の軸孔３３２と係合させることができるため、パチンコ機ＰＭの設置場所等を考慮した作業性に応じて、外枠１に対して前枠２を左右どちら側からでも容易に装着させることができる。
【０１２４】
さらに続いて、前枠２を直立方向に傾動させると、図１６に示すように、軸部３１３は固定側板状部３３１（壁部３３５）の後方から飾り部材３５０の逃げ孔部３５２およびガイド孔３３３を通過して軸孔３３２に位置し、軸部３１３は軸孔３３２と係合する。
【０１２５】
そして、軸係合部材３６０を下方へ移動するようにネジ回転させると、軸係合部材３６０の軸係合部３６１が下方へ移動して軸係合部材３６１の周部３６１ａが軸部３１３の上端部と係合し、軸係合部３６１（周部３６１ａ）により軸部３１３の後方への移動、すなわち、軸部３１３のガイド孔３３３への移動が規制されて、軸部３１３の側方（前後左右）にかかる荷重が受け止められる状態となる。
【０１２６】
このようにして、軸部３１３を第２固定側板状部３３１の後方からガイド孔３３３に通過させて軸孔３３２と係合させ、この状態で軸係合部材３６０の軸係合部３６１を軸部３１３の上端部と係合させて軸部３１３のガイド孔３３３への移動を規制することで、枠上部揺動金具３１０と枠上部固定金具３２０とのヒンジ接続が行われるため、外枠１に対して前枠２を容易に装着させることができるとともに、一旦装着した後は、その揺動位置に拘わらず前枠２を外枠１から外れることなくしっかりと保持することができる。
【０１２７】
さらに、軸係合部材３６０の軸係合部３６１が軸部３１３の上端部と係合した状態で、飾り部材３５０の軸係合部材取付孔３５３に充填固着材３７０を充填し、充填固着材３７０により軸係合部材取付孔３５３を塞いで軸係合部材３６０の上方を覆うようにする。これにより、軸係合部材３６０の軸係合部３６１と軸部３１３の上端部との係合状態が解除されたときに係合解除操作の痕跡が残るため、パチンコ機ＰＭの輸送中や設置後に行われる軸部３１３や軸孔３３２等に対する不正行為をより早く発見することができる。
【０１２８】
この結果、枠上部揺動金具３１０の軸部３１３が枠上部固定金具３２０の軸孔３３２および軸係合部材３６０の軸係合部３６１と係合して軸部３１３の側部が保持された状態で、枠上部揺動金具３１０と枠上部固定金具３２０とがヒンジ接続され、軸部３１３を揺動軸として前枠２が外枠１に対して揺動可能になる。なお、枠上部ヒンジ機構３００における前枠２の外枠１に対する揺動軸は、枠下部ヒンジ構造２００における前枠２の外枠１に対する揺動軸と共通になっている。
【０１２９】
なお、枠上部揺動金具３１０と枠上部固定金具３２０とを分離するには、まず、充填固着材３７０を飾り部材３５０の軸係合部材取付孔３５３から除去した後、軸係合部材３６０を上方へ移動するようにネジ回転させて軸係合部材３６０の軸係合部３６１と軸部１１３の上端部との係合状態を解除し、前枠２を後方に傾動させるようにすればよい。
【０１３０】
このため、以上のような構成の枠上部ヒンジ機構３００によれば、軸部３１３を第２固定側板状部３３１の後方からガイド孔３３３に通過させて軸孔３３２と係合させ、この状態で軸係合部材３６０の軸係合部３６１（周部３６１ａ）を軸部３１３の上端部と係合させて軸部３１３のガイド孔３３３への移動を規制することで、枠上部揺動金具３１０と枠上部固定金具３２０とのヒンジ接続が行われるため、外枠１に対して前枠２を容易に装着させることができるとともに、一旦装着した後は、その揺動位置に拘わらず前枠２を外枠１から外れることなくしっかりと保持することができる。
【０１３１】
また、軸係合部３６１の周部３６１ａが軸部３１３の上端部と係合するときに、軸部３１３の上端部から上方へ突出して形成された半球形状の凸部３１３ａが軸係合部３６１の底部３６１ｂに当接するため、軸部３１３を中心軸とした前枠２の揺動を円滑に行うことができる。さらに、軸部３１３の凸部３１３ａが軸係合部３６１の底部３６１ｂに当接するため、軸部３１３、すなわち前枠２の外枠１に対する上動が規制され、前枠２を無理に上動させて枠下部ヒンジ機構２００に構成される枠下部揺動金具２２０と枠下部固定金具２１０とを不正に分離し、前枠２が外枠１から不正に外されることを防止することができる。
【０１３２】
また、軸係合部材３６０の十字溝３６２により、ドライバ等の工具を用いなければ軸係合部材３６０を回転させることが困難であるため、軸係合部材３６０の軸係合部３６１と軸部３１３の上端部との係合状態が容易に解除されることを防止することができる。さらに、充填固着材３７０により、軸係合部材３６０の軸係合部３６１と軸部３１３の上端部との係合状態が解除されたときに係合解除操作の痕跡が残るため、パチンコ機ＰＭの輸送中や設置後に行われる軸部３１３や軸孔３３２等に対する不正行為をより早く発見することができる。
【０１３３】
また、ガイド部材３４０により、枠上部揺動金具３１０の軸部３１３を枠上部固定金具３２０の左右どちら側からでも枠上部固定金具３２０の軸孔３３２と係合させることができるため、パチンコ機ＰＭの設置場所等を考慮した作業性に応じて、外枠１に対して前枠２を左右どちら側からでも容易に装着させることができる。さらに、飾り部材３５０により、枠上部揺動金具３１０の軸部３１３や、枠上部固定金具３２０の軸孔３３２およびガイド孔３３３が外部から見て飾り部材３５０に覆われた状態となり、パチンコ機ＰＭの美感が向上するとともに、軸部３１３等に対する不正行為の抑止が期待できる。
【０１３４】
なお、上述の各実施形態において、前枠２およびガラス扉５の上部には、所定開放保持角度（例えば、１１０度）においてガラス扉５を前枠２に対して開放保持する開放保持機構４００が設けられている。そこで、開放保持機構４００について図１７〜図１９を参照して説明する。ここで、図１７は開放保持機構４００の側面図、図１８は開放保持機構４００の分解斜視図、そして図１９は開放保持機構４００の平面図である。
【０１３５】
開放保持機構４００は、図１８に示すように、ガラス扉５を前枠２に対して開放支持する開放支持部材４１０と、開放支持部材４１０が収容可能に接続される収容部材４２０と、開放支持部材４１０と収容部材４２０とを接続させる接続部材４３０と、開放支持部材４１０が係止する係止部材４４０とを主体に構成される。
【０１３６】
開放支持部材４１０は、所定板厚の金属板材を用い、切断、折り曲げ、孔あけ等の成形手段により各図に示す形状に形成され、所定開放保持角度においてガラス扉５を前枠２に対して開放支持可能に構成される。開放支持部材４１０の一端には、収容部材係合軸部４１１が下方へ突出して固着されており、収容部材４２０のスライド係合孔４２３とスライド移動可能に係合するように構成されている。
【０１３７】
開放支持部材４１０の他端には、ピン係止孔４１２が形成されており、収容部材４２０の収容係止ピン４２５および係止部材４４０の開放保持係止ピン４４３に係止可能に構成されている。開放支持部材４１０の側部には、把持部４１３が直角に折り曲げられて形成されており、把持部４１３を把持して開放支持部材４１０をスライド移動させやすいようになっている。
【０１３８】
収容部材４２０は、ガラス扉５の上部裏面側に固定される収容部材基部４２１と、この収容部材基部４２１から直角に折り曲げられて後方に水平に突出する収容部材板状部４２２とを主体に構成され、所定板厚の金属板材を切断、孔開けおよび曲げ形成して図示する形状に形成される。収容部材基部４２１は、リベットやネジ等の締結手段によりガラス扉５の裏面側上部に固定され、これにより収容部材４２０ガラス扉５の上部裏面側に固設される。
【０１３９】
なお、収容部材４２０は、後方に水平に突出する収容部材板状部４２２を備えてガラス扉５の裏面側上部に固設されることで、針金やセル板等の異物が遊技盤１０の表面側に入り込みにくくなり、パチンコ機ＰＭにおける遊技盤１０への不正行為を防止する機能を有している。また、本実施形態における収容部材４２０は、ガラス扉５の上側補強板金としての機能を有している。
【０１４０】
収容部材板状部４２２の右方（図１８における左方）には、スライド係合孔４２３が左方へ延びて形成されており、開放支持部材４１０の収容部材係合軸部４１１がスライド移動可能に係合するようになっている。スライド係合孔４２３の左端（図１８における右端）には、開放保持係止孔４２４が形成されており、収容部材係合軸部４１１が係止可能に構成されている。
【０１４１】
収容部材板状部４２２の左端（図１８における右端）には、開放支持部材４１０のピン係止孔４１２が係止可能な収容係止ピン４２５が固着されている。そして、開放支持部材４１０の収容部材係合軸部４１１をスライド係合孔４２３の右端（図１８における左端）までスライド移動させた状態で、開放支持部材４１０をガラス扉５の方に揺動させてピン係止孔４１２を収容係止ピン４２５に係止させると、開放支持部材４１０が収容部材板状部４２２の上部に平行に位置し、これにより開放支持部材４１０が収容部材４２０に収容されるようになっている。
【０１４２】
接続部材４３０は、樹脂材料を用いて射出成形等の成形手段により円筒状に一体的に形成される。接続部材４３０の中央部には嵌合孔４３１が形成されており、開放支持部材４１０の収容部材係合軸部４１１と嵌合するようになっている。
【０１４３】
そして、開放支持部材４１０の収容部材係合軸部４１１を収容部材板状部４２２のスライド係合孔４２３に上方から通過させた状態で、接続部材４３０の嵌合孔４３１に収容部材係合軸部４１１を圧入して嵌合させることで、接続部材４３０に開放支持部材４１０の上方への移動が規制されて、収容部材係合軸部４１１がスライド係合孔４２３とスライド移動可能に係合する。これにより、収容部材係合軸部４１１を揺動軸として開放支持部材４１０が収容部材４２０に揺動自在に且つスライド移動自在に連結される。
【０１４４】
係止部材４４０は、前枠２の上部裏面側に固定される係止部材基部４４１と、この係止部材基部４４１から直角に折り曲げられて前方に水平に突出する係止部材板状部４４２とを主体に構成され、所定板厚の金属板材を切断、孔開けおよび曲げ形成して図示する形状に形成される。係止部材基部４４１には複数の固定孔４４１ａ，…が孔開け形成されており、リベットやネジ等の締結手段をこれら複数の固定孔４４１ａ，…に通過させて前枠２へ締結固定させることで、係止部材基部４４１すなわち係止部材４４０が前枠２の上部正面側に固設される。なお、係止部材４４０は、遊技盤１０の着脱の妨げにならないように、前枠２における収容枠２ａの上方に設けられるのが好ましい。
【０１４５】
係止部材板状部４４２の前端部近傍には、下方に突出する開放保持係止ピン４４３が固着されており、開放支持部材４１０のピン係止孔４１２が係止可能に構成されている。そして、ガラス扉５が前枠２に対して所定開放保持角度まで揺動させた状態で、開放支持部材４１０のピン係止孔４１２を開放保持係止ピン４４３に係止させるとともに、開放支持部材４１０の収容部材係合軸部４１１をスライド移動させて収容部材板状部４２２の開放保持係止孔４２４に係止させると、図１８および図２０に示すように、開放支持部材４１０によりガラス扉５が所定開放保持角度において前枠２に対して開放支持されるようになっている。
【０１４６】
このように構成される開放保持機構４００において、開放支持部材４１０を収容部材４２０に収容するには、開放支持部材４１０の収容部材係合軸部４１１をスライド係合孔４２３の右端（図１８における左端）までスライド移動させ、この状態で開放支持部材４１０をガラス扉５の方に揺動させてピン係止孔４１２を収容部材４２０の収容係止ピン４２５に係止させる。これにより、開放支持部材４１０が収容部材板状部４２２の上部に平行に位置して収容部材４２０に収容され、常にはこの状態でパチンコ機ＰＭが使用に供される。
【０１４７】
一方、所定開放保持角度（例えば、１１０度）においてガラス扉５を前枠２に対して開放保持するには、まず、図１９の二点鎖線で示すように、ガラス扉５を前枠２に対して少しだけ（所定開放保持角度より少ない角度だけ）開放揺動させる。次に、収容部材４２０に収容された開放支持部材４１０を前枠２の方に揺動させてピン係止孔４１２と収容係止ピン４２５との係止状態を解除するとともに、ピン係止孔４１２を係止部材４４０の開放保持係止ピン４４３に係止させる。
【０１４８】

BACKGROUND OF THE INVENTION
The present invention relates to a hinge mechanism that is disposed between a base member and an opening / closing member and connects the base member and the opening / closing member so as to be swingable and openable relative to each other.
[0002]
[Prior art]
The hinge mechanism as described above is widely used in gaming machines, and one example thereof is a hinge mechanism disposed between an outer frame and a front frame in a pachinko machine. The hinge mechanism of a pachinko machine is composed of a pair of upper and lower hinge mechanisms disposed on the upper left and right sides of the front of an outer frame having an outer opening and an opening / closing front frame adapted to the opening surface area.
[0003]
As shown in FIG. 20, each of the upper and lower hinge mechanisms includes a first hinge member 500 in which a shaft support hole 502 is formed in a first plate-like portion 501 arranged horizontally, and a second hinge arranged horizontally. The second hinge member 505 is fixedly provided with a support shaft 507 protruding upward from the plate-like portion 506. In the pair of upper and lower hinge mechanisms having such a configuration, by inserting the support shaft 507 into the shaft support hole 502 and connecting the first and second hinge members 500 and 505 horizontally and relatively rotatably, the outer frame On the other hand, the front frame is configured to support the swingable opening / closing and detachable.
[0004]
However, in the conventional hinge mechanism as described above, when the front frame is to be attached to the outer frame, the shaft support hole 502 and the support shaft 507 of both the upper and lower hinge mechanisms are aligned together (axis There was a problem that it was not easy to work because it had to be engaged (with the hearts aligned). In particular, when mounting in a gaming facility, the outer frame is fixed to the game island and cannot be moved, and the front frame is incorporated with a game board, back set board, control device, etc. For example, since the hinge mechanism is located on the side away from the center of gravity, there is a problem that the mounting operation for positioning the upper and lower two locations is extremely difficult.
[0005]
In view of such a problem, for example, as shown in FIG. 21, an introduction opening 503 connected to the shaft support hole 502 from the outer surface is formed in the plate-like portion 501 of the first hinge member 500 ′, and the second hinge member 505. The left and right sides of the supporting shaft 507 are cut into a flat shape to form flat portions 507a and 507a, and the width of the left and right flat portions 507a and 507a of the supporting shaft 507 is configured to be slightly narrower than the width of the introduction opening 503. It is known.
[0006]
In this configuration, the support shaft 507 can be inserted into the shaft support hole 502 from the side by passing the left and right plane portions 507a and 507a of the support shaft 507 through the introduction opening 503, and in this state, the first and second If the hinge members 500 ′ and 505 ′ are horizontally rotated relative to each other, the left and right plane portions 507 a and 507 a are rotatably held in the shaft support hole 502. With this configuration, the support shaft 507 can be moved in the lateral direction and fitted into the shaft support hole 502 without aligning the shaft support hole 502 and the support shaft 507 in the vertical direction. The work of attaching the front frame becomes easy.
[0007]

Japanese Patent Laid-Open No. 11-156025
[0008]
[Problems to be solved by the invention]
However, in this configuration, when the front frame is swung to a position where the introduction opening 503 of the shaft support hole 502 and the left and right flat portions 507a and 507a of the support shaft 507 face each other, the support shaft 507 is detached from the shaft support hole 502. There is a problem that the front frame comes off. Furthermore, since the engagement (insertion) direction of the support shaft 507 is specified, depending on the installation location of the pachinko machine such as the end of the game island, it is very difficult to attach the front frame to the outer frame by interfering with island decorations. There is also the problem of becoming.
[0009]
The present invention has been made in view of such a problem, and an opening / closing member such as a front frame can be easily attached to a base member such as an outer frame from either the left or right side, and once attached. After that, an object of the present invention is to provide a hinge mechanism of a gaming machine configured to be able to hold the opening / closing member firmly without detaching from the base member regardless of the swinging position.
[0010]
[Means for Solving the Problems]
