【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２４（ａ）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、前枠を上動させたり等して上下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２４（ｂ）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。

【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。
【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（例えば、実施形態における枠上部ヒンジ機構３００および枠下部ヒンジ機構２００）における一方のヒンジ機構（例えば、実施形態における枠上部ヒンジ機構３００）であって、開閉部材に固設された上方に突出する軸部を有する第１ヒンジ部材（例えば、実施形態における枠上部揺動金具３１０）と、ベース部材に固設され、軸部と係合する軸孔と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３２０および飾り部材３４０）と、第２ヒンジ部材に、軸部が軸孔に位置するときに軸部と係合可能な軸係合位置と、軸部との係合を解除する非軸係合位置とに変位可能に設けられた軸係合部材と、軸係合部材を軸係合位置に向けて付勢する弾性部材とを備えて構成される。
【００１１】
そして、第２ヒンジ部材は、ベース部材に固設されて軸孔およびガイド孔が形成される固定金具と、固定金具に対して固定金具の上方を覆うように取り付けられた飾り部材とを有し、軸係合部材は、飾り部材の内部に非軸係合位置と軸係合位置とに上下に変位可能に取り付けられ、ガイド孔内を軸部が後方から前方へ移動したときに軸部に当接して非軸係合位置の方へ押圧されるように構成されており、飾り部材の上部にピン孔が上下に貫通して形成されるとともに、軸係合部材の上端部にピン孔内を通過可能な係合ピン部が上方へ突出して形成され、ピン孔の深さは、軸係合部材が軸係合位置に位置するときに係合ピン部の先端がピン孔内に位置し、軸係合部材が非軸係合位置に位置するときに係合ピン部の先端がピン孔から上方へ突出する深さであり、軸部がガイド孔内に導入されてガイド孔に沿って前方へ移動すると軸係合部材が軸部に押圧されて非軸係合位置へ変位し、軸部が軸孔に位置すると軸係合部材が弾性部材の付勢力を受けて軸係合位置へ変位し軸部と係合して、軸部が軸孔内に保持されるように構成される。
【００１２】
このような構成の遊技機のヒンジ機構によれば、軸部がガイド孔内に導入されてガイド孔に沿って前方へ移動すると軸係合部材が軸部に押圧されて非軸係合位置へ変位し、軸部が軸孔に位置すると軸係合部材が弾性部材の付勢力を受けて軸係合位置へ変位し軸部と係合することで、軸係合部材により軸部のガイド孔への移動が規制された状態で軸部が軸孔と係合するため、開閉部材を上動させることなく第１ヒンジ部材と第２ヒンジ部材とをヒンジ接続させることができ、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。
なお、上述の発明では、軸係合部材が軸係合位置に位置するときに弾性部材の変形を規制可能なロック機構を備え、軸係合部材が軸部と係合した状態でロック機構により弾性部材の変形を規制可能に構成されることが好ましい。
また、上述の発明において、遊技機は、前記ベース部材である外枠と、外枠に横開き揺動開閉自在に取り付けられた前記開閉部材である前枠と、外枠および前枠の側部上下において外枠と前枠とに跨って配設され、前枠を外枠に対して横開き揺動開閉自在にヒンジ接続させる前記上下一対のヒンジ機構と、前枠に横開き揺動開閉自在に取り付けられたガラス扉とを備え、前枠およびガラス扉の上部に、ガラス扉が前枠に対し所定開放保持角度だけ開放揺動した状態を保持する開放保持機構が設けられ、開放保持機構は、ガラス扉を前枠に対して所定開放保持角度で開放支持する開放支持部材と、開放支持部材の一端側と接続されて開放支持部材を収容可能な収容部材と、前枠の上部に固設されて開放支持部材がガラス扉を開放支持するときに開放支持部材の他端側が係止する係止部材とを有し、常には、開放支持部材が収容部材に収容された状態で、遊技機が使用に供されるように構成されており、第２ヒンジ部材に、前枠に対するガラス扉の所定開放規制角度を超えた開放揺動を規制する開放角度規制ピンが設けられるとともに、ガラス扉に、所定開放規制角度までガラス扉を開放揺動させると開放角度規制ピンに当接するピン当接部が設けられ、ピン当接部がガラス扉の側部裏面側に取り付けられた補強板金と一体に形成されるとともに、
収容部材がガラス扉の上側補強板金としてガラス扉の上部裏面側に取り付けられていることが好ましい。
また、上述の発明では、ピン孔の上部を塞ぐ不正操作識別手段を備え、不正操作識別手段は、軸係合部材が軸部と係合した状態で用いられ、軸係合部材と軸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を残すように構成されることが好ましい。
【００１３】
【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。
【００１４】
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。
【００１５】
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。
【００１６】
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。
【００１７】
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２１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２１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。
【００１８】
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。
【００１９】
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。
【００２０】
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。
【００２１】
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。
【００２２】
まず、図３〜図９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９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。
【００２３】
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の上面側に取り付けられた飾り部材１４０と、一端側が枠上部固定金具１２０に固定された軸係合部材１５０と、軸係合部材１５０の一端側を枠上部固定金具１２０に固定するための弾性部材固定ピン１６０とを主体に構成される（なお、枠上部揺動金具１１０が本発明における第１ヒンジ部材となっており、枠上部固定金具１２０および飾り部材１４０が本発明における第２ヒンジ部材となっている）。
【００２４】
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。
【００２５】
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、面取り１１３ａが形成されている。
【００２６】
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。
【００２７】
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。
【００２８】
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。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。
【００２９】
第１固定側板状部１２５の後部には、軸係合部材１５０の一端側を第１固定側板状部１２５（枠上部固定金具１２０）に固定するための弾性部材取付孔１２６が側部に２つの平面部を有する長孔状に形成されており、弾性部材固定ピン１６０の嵌合部１６１が通過して嵌合するようになっている。
【００３０】
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。
【００３１】
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。
【００３２】
第２固定側板状部１３１の左右には、飾り部材１４０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１４０を第２固定側板状部１３１に取り付けるための皿ネジ１４９の頭部に合わせた形状となっている。
【００３３】
なお、図６および図７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。また、図５および図７に示すように、外枠１の左上部上面側にはザグリ部１３８が形成されており、軸係合部材１５０および弾性部材固定ピン１６０が外枠１と干渉しないようになっている。
【００３４】
飾り部材１４０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、そして軸係合部材１５０が外部から見て飾り部材１４０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や軸係合部材１５０等に対する不正行為の抑止が期待できる。
【００３５】
飾り部材１４０の左右には、飾り部材取付部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１４１，１４１にそれぞれネジ固定することで、飾り部材１４０が第２固定側板状部１３１に取り付けられるようになっている。
【００３６】
飾り部材１４０の後側部には、逃げ孔部１４２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および軸係合部材１５０が通過可能に構成されている。
【００３７】
飾り部材１４０の前端部近傍には、枠上部揺動金具１１０の軸部１１３と当接する軸受け部１４３が形成されている。軸受け部１４３は、枠上部固定金具１２０における軸孔１３２の形状に合わせた半円弧状に形成され、軸受け部１４３の最大内幅は、軸部１１３の径より僅かに大きくなっている。そして、図７に示すように（図１１も参照）、軸部１１３が枠上部固定金具１２０の軸孔１３２と係合すると軸部１１３の前側部と当接し、軸部１１３の側前方にかかる荷重を受け止めるようになっている。これにより、軸部１１３の前側部をより安定した状態で保持することができる。
【００３８】
軸係合部材１５０は、所定板厚の金属板を切断、折り曲げ、孔あけなどの成形手段により板バネ状に形成され、上下方向に大きな曲げ弾性を有するように構成される。軸係合部材１５０の一端側には、固定ピン嵌合孔１５１が側部に２つの平面部を有する長孔状に形成されており、弾性部材固定ピン１６０の嵌合部１６１が通過して嵌合するようになっている。軸係合部材１５０の中央部一端側には、曲げ部１５２がＵ字状に曲げられて形成されおり、軸係合部材１５０を上下方向に弾性変性させやすくなっている。
【００３９】
軸係合部材１５０の他端部には、枠上部固定金具１２０の軸孔１３２に対向して軸係合部１５３が形成されている。軸係合部１５３は、枠上部揺動金具１１０の軸部１１３の形状に合わせた円弧状に形成され、図７に示すように（図１１も参照）、軸部１１３が軸孔１３２に位置するときに軸部１１３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への移動を規制するとともに、軸部１１３の側後方にかかる荷重を受け止めるように構成される。
【００４０】
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と係合した軸係合部１５３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。さらに、軸係合部１５３が軸部１１３の形状に合わせた円弧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。
【００４１】
軸係合部材１５０の下面側には、軸係合部１５３に繋がって後方へ水平に延びる第１軸当接部１５４と、第１軸当接部１５４に繋がって上斜め後方に延びる第２軸当接部１５５とが形成されており、図９（ｂ）に示すように、枠上部揺動金具１１０の軸部１１３が第２固定側板状部１３１におけるガイド孔１３３の後端部付近に位置するときに第２軸当接部１５５に当接し、軸部１１３がガイド孔１３３の中央部から前端部付近に位置するときに第１軸当接部１５４に当接するようになっている。すなわち、軸部１１３がガイド孔１３３内に導入されて前方に移動するときに第２軸当接部１５５と第１軸当接部１５４との順で当接し、軸係合部材１５０が軸部１１３に押圧されて軸係合部材１５０の一端側を基点に上方へ曲げられるように弾性変形する。
【００４２】
弾性部材固定ピン１６０は、金属製の丸棒からピン形状に切り出し成形され、弾性部材固定ピン１６０の胴部には、第１固定側板状部１２５の弾性部材取付孔１２６と軸係合部材１５０の固定ピン嵌合孔１５１とに嵌合可能な嵌合部１６１が形成されている。嵌合部１６１は、弾性部材取付孔１２６および固定ピン嵌合孔１５１の形状に合わせて側部に２つの平面部１６１ａ，１６１ａを有する円柱状に形成される。そして、嵌合部１６１を弾性部材取付孔１２６および固定ピン嵌合孔１５１に通過させて嵌合させた後、嵌合部１６１の一端側にカシメ加工を施すことにより、軸係合部材１５０の一端側が第１固定側板状部１２５の下方に位置するとともに、他端側が壁部１３５におけるガイド孔１３３を通過して第２固定側板状部１３１の上方に位置する状態で、軸係合部材１５０の一端側が第１固定側板状部１２５に取付固定される。
【００４３】
これにより、軸係合部材１５０は、上下方向に大きな曲げ弾性を有するため、枠上部固定金具１２０の上面側において、軸部１１３が軸孔１３２に位置するときに軸係合部１５３が軸部１１３と係合可能な軸係合位置と、軸係合部１５３と軸部１１３との係合を解除する非軸係合位置とに変位（上下に揺動）可能となる。また、嵌合部１６１の側部二箇所に平面部１６１ａ，１６１ａが設けられているため、軸係合部材１５０が水平旋回することなく軸係合部材１５０の一端側を第１固定側板状部１２５に取付固定することができる。なお、平面部は、嵌合部１６１（および弾性部材取付孔１２６と固定ピン嵌合孔１５１）の側部一箇所に形成されるようにしてもよい。
【００４４】
次に、枠下部ヒンジ機構２００について図１２を参照して説明する。ここで、図１２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。
【００４５】
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。
【００４６】
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。
【００４７】
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。
【００４８】
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。
【００４９】
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。
【００５０】
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。
【００５１】
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。
【００５２】
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の右側方から接近させ、図９（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。
【００５３】
そして、前枠２を直立方向に傾動させると、軸部１１３は第２固定側板状部１３１（壁部１３５）の後方から飾り部材１４０の逃げ孔部１４２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。
【００５４】
このとき、図８および図９（ｂ）に示すように、軸部１１３がガイド孔１３３内に導入されて前方に移動するときに、軸部１１３は軸係合部材１５０の第２軸当接部１５５と第１軸当接部１５４とに順に当接し、軸係合部材１５０が軸部１１３に押圧されて上方へ曲げられるように弾性変形して非軸係合位置へ変位（上方へ揺動）する。
【００５５】
そして、図７に示すように（図１１も参照）、軸部１１３が軸孔１３２に位置すると、軸係合部材１５０が弾性力により軸係合位置へ変位（下方へ揺動）して軸係合部材１５０の軸係合部１５３が軸部１１３と係合し、この状態で軸部１１３が軸孔１３２内に保持される。このようにして、軸係合部材１５０の軸係合部１５３により軸部１１３のガイド孔１３３への移動が規制された状態で１１３軸部が軸孔１３２と係合するため、前枠２を上動させることなく容易に枠上部揺動金具１１０と枠上部固定金具１２０とをヒンジ接続させることができ、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。
【００５６】
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１５０の軸係合部１５３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。
【００５７】
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。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、軸係合部材１５０を上方へ曲げて（弾性変形させて）軸係合部材１５０の軸係合部１５３と軸部１１３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。
【００５８】
また、本実施形態において、軸係合部材１５０の軸係合部１５３が枠上部揺動金具１１０の軸部１１３と係合した状態で軸係合部材１５０の上方への曲げ変形を規制可能なロック機構を設けてもよい。例えば、図２４に示すように、下端部に半球形状に形成された弾性部材当接部１７１と、上端部に形成されたドライバ等の工具と係合可能な十字溝１７２とを有するネジ形状に形成されたロック部材１７０を飾り部材１４０′の後部にネジ回転可能に取り付け、軸係合部１５３が軸部１１３と係合した状態でロック部材１７０を下方へ移動するようにネジ回転させて、弾性部材当接部１７１を軸係合部材１５０の他端部上面側近傍に位置させるようにしてもよい。
【００５９】
このようにすれば、軸係合部材１５０を上方へ曲げ変形させようとしても、軸係合部材１５０の他端側がロック部材１７０の弾性部材当接部１７１に当接して、軸係合部材１５０の上方への曲げ変形が規制されるため、軸係合部材１５０が上方へ曲げ変形されて軸係合部１５３と軸部１１３との係合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、ロック部材１７０の十字溝１７２により、ドライバ等の工具を用いなければロック部材１７０を回転させることが困難であるため、軸係合部１５３と軸部１１３との係合状態が容易に解除されることをより確実に防止することができる。
【００６０】
次に、扉上部ヒンジ機構５０について図１０および図１１を参照して説明する。ここで、図１０は扉上部ヒンジ機構５０の正面図（部分断面図）、図１１は扉上部ヒンジ機構５０の平面拡大図（部分断面図）である。
【００６１】
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。
【００６２】
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２１を参照）の上端部に繋がって形成されている。
【００６３】
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。
【００６４】
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。
【００６５】
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。
【００６６】
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。
【００６７】
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１０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。
【００６８】
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１０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。
【００６９】
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１０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。
【００７０】
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。
【００７１】
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１０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。
【００７２】
そして、図１０および図１１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。
【００７３】
次に、中間ヒンジ機構７０について図１３を参照して説明する。ここで、図１３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。
【００７４】
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。
【００７５】
揺動側板状部７３の左端部（図１３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。
【００７６】
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。
【００７７】
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。
【００７８】
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。
【００７９】
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。
【００８０】
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。
【００８１】
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。
【００８２】
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。
【００８３】
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。
【００８４】
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。
【００８５】
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がガイド孔１３３内に導入されてガイド孔１３３に沿って前方へ移動すると軸係合部材１５０が軸部１１３に押圧されて非軸係合位置へ変位し、軸部１１３が軸孔１３２に位置すると軸係合部材１５０（軸係合部１５３）が弾性力を利用して軸係合位置へ変位し軸部１１３と係合することで、軸係合部材１５０により軸部１１３のガイド孔１３３への移動が規制された状態で軸部１１３が軸孔１３２と係合するため、前枠２を上動させることなく容易に枠上部揺動金具１１０と枠上部固定金具１２０とをヒンジ接続させることができ、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。
【００８６】
また、軸係合部１５３が軸部１１３の形状に合わせた円弧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、飾り部材１４０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、そして軸係合部材１５０が外部から見て飾り部材１４０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や軸係合部材１５０等に対する不正行為の抑止が期待できる。また、曲げ弾性を有する軸係合部材１５０に軸係合部１５３を形成することで、軸係合部材１５０を、（軸係合部材１５０を）軸係合位置に向けて付勢する付勢手段と一体に設けることができるため、部品点数を少なくすることができる。さらに、軸係合部材１５０（軸係合部１５３）が上下変位して軸部１１３と係合するため、軸係合部材を水平変位させる場合に比べて軸係合部１５３を軸部１１３の後側方により広く接触させることができ、軸係合部軸部１１３との係合による効果が得られやすい。
【００８７】
次に、枠上部ヒンジ機構の第二実施形態について図１４〜図２０を参照して説明する。ここで、図１４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、図１５は枠上部ヒンジ機構３００に構成される軸係合部材３６０の取付部付近を示す拡大斜視図、図１６は枠上部ヒンジ機構３００の分解平面図（部分断面図）、図１７は枠上部ヒンジ機構３００の平面図（部分断面図）、図１８は枠上部ヒンジ機構３００の側面図（部分断面図）、そして図１９は枠上部ヒンジ機構３００に構成される枠上部揺動金具３１０と枠上部固定金具３２０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。
【００８８】
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。
【００８９】
第二実施形態における枠上部ヒンジ機構３００は、図１４〜図１６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の上面側に取り付けられた飾り部材３４０と、一端側が枠上部固定金具３２０に固定された弾性部材３５０と、飾り部材３４０の内部に上下移動可能に取り付けられた軸係合部材３６０（図１４では図示略）とを主体に構成される（なお、枠上部揺動金具３１０が本発明における第１ヒンジ部材となっており、枠上部固定金具３２０および飾り部材３４０が本発明における第２ヒンジ部材となっている）。
【００９０】
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３１１（図１７を参照）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３１１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。
【００９１】
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、面取り３１３ａが形成されており、図１９（ａ）に示すように、軸係合部材３６０の第２当接部３６５と滑らかに当接するようになっている。
【００９２】
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（図示せず）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。
【００９３】
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。
【００９４】
第１固定側板状部３２５の後部には、弾性部材取付孔３２６がネジ溝（図示せず）を有して孔あけ形成されており、飾り部材３４０および弾性部材３５０の一端側を第１固定側板状部３２５（枠上部固定金具３２０）に固定するための皿ネジ３４９がネジ固定されるようになっている。
【００９５】
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。
【００９６】
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。
【００９７】
なお、第１固定側板状部３２５の前端部には、逃げ孔３２７がガイド孔３３３に繋がって形成されており、弾性部材３５０が第１固定側板状部３２５（および壁部３３５）と干渉しないようになっている。
【００９８】
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。
【００９９】
また、図１９（ａ），（ｂ）に示すように、枠上部固定金具３２０が固設される外枠１の左上部下面側には切り欠き部３３９が形成されており、第一実施形態における枠上部ヒンジ機構１００と同様に、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ときに、枠上部揺動金具３１０が外枠１と干渉しないようになっている。
【０１００】
飾り部材３４０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、枠上部固定金具３２０における第１固定側板状部３２５および第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、第１固定側板状部３２５の逃げ孔３２７や、第２固定側板状部３３１の軸孔３３２およびガイド孔３３３、また、枠上部揺動金具３１０の軸部３１３や、弾性部材３５０および軸係合部材３６０が外部から見て飾り部材３４０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や弾性部材３５０等に対する不正行為の抑止が期待できる。
【０１０１】
飾り部材３４０の左右には、第２飾り部材取付部３４１，３４１が第２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、第２飾り部材取付部３４１にそれぞれネジ固定することで、飾り部材３４０の前部が第２固定側板状部３３１（枠上部固定金具３２０）の上面側に取付固定されるようになっている。
【０１０２】
飾り部材３４０の後部には、第１飾り部材取付部３４２が第１取付孔３４２ａを有して形成されており、この取付孔３４２ａの形状が皿ネジ３４９の頭部に合わせた形状となっている。第１飾り部材取付部３４２の下面側には、上部および左右に壁面を有する弾性部材収容部３４３が弾性部材３５０の一端側の形状に合わせて形成されている。
【０１０３】
飾り部材３４０の前端部近傍には、枠上部揺動金具３１０の軸部３１３と当接する軸受け部３４４が形成されている。軸受け部３４４は、枠上部固定金具３２０における軸孔３３２の形状に合わせた半円弧状に形成され、軸受け部３４４の最大内幅は、軸部３１３の径より僅かに大きくなっている。そして、図１７および図１８に示すように、軸部３１３が軸孔３３２と係合すると軸部３１３の前側部と当接し、軸部３１３の側前方にかかる荷重を受け止めるようになっている。これにより、軸部３１３の前側部をより安定した状態で保持することができる。
【０１０４】
飾り部材３４０の中央内部には、図１５に示すように、軸係合部材取付部３４５が形成されており、軸係合部材３６０の前後左右方向への移動を規制して、軸係合部材３６０が上下移動可能に取り付けられる。飾り部材３４０の中央上部には、ピン孔３４６が孔あけ形成されており、軸係合部材３６０の係合ピン部３６２が上下に通過するようになっている。飾り部材３４０の上部内側には、図１９（ａ），（ｂ）に示すように、逃げ部３４７が形成されており、弾性部材３５０が上方へ（曲げられ）弾性変形したときに飾り部材３４０と干渉しないようになっている。
【０１０５】
弾性部材３５０は、所定板厚の金属板を切断、折り曲げ、孔あけなどの成形手段により板バネ状に形成され、上下方向に大きな曲げ弾性を有するように構成される。弾性部材３５０の一端側には、弾性部材固定孔３５１が孔あけ形成されており、皿ネジ３４９が通過するようになっている。
【０１０６】
そして、皿ネジ３４９を飾り部材３４０の第１取付孔３４２ａおよび弾性部材固定孔３５１の順に通過させて、第１固定側板状部３２５の弾性部材取付孔３２６にネジ固定することにより、飾り部材３４０の後部が第１固定側板状部３２５（枠上部固定金具３２０）に固定されるとともに、弾性部材３５０の一端側が飾り部材３４０の弾性部材収容部３４３に位置して、弾性部材３５０の一端側が弾性部材収容部３４３の上壁面と第１固定側板状部３２５とに挟持されるとともに弾性部材収容部３４３の左右壁面により弾性部材３５０の水平旋回が規制された状態となり、この状態で弾性部材３５０の一端側が第１固定側板状部３２５（枠上部固定金具３２０）に固定される。
【０１０７】
弾性部材３５０の中央部一端側には、曲げ部３５２がＵ字状に曲げられて形成されおり、弾性部材３５０を上下方向に弾性変性させやすくなっている。弾性部材３５０の他端部には、ピン係合口３５３がＵ字状に形成されており、軸係合部材３６０の係合溝部３６３と係合するようになっている。
【０１０８】
軸係合部材３６０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ブロック状に一体的に形成され、飾り部材３４０の軸係合部材取付部３４５に、枠上部揺動金具３１０の軸部３１３と係合可能な軸係合位置（図１８を参照）と、軸部１１３との係合を解除する非軸係合位置（図１９（ｂ）を参照）とに上下移動可能に取り付けられる。
【０１０９】
軸係合部材３６０の前側部には、枠上部固定金具３２０の軸孔３３２に対向して軸係合部３６１が形成されている。軸係合部３６１は、軸部３１３の形状に合わせた円弧状に形成され、図１７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部３１３と係合し、軸部３１３の側後方にかかる荷重を受け止めるとともに、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への移動を規制するように構成される。
【０１１０】
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と係合した軸係合部３６１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。
【０１１１】
さらに、軸係合部３６１が軸部３１３の形状に合わせた円弧状に形成されているため、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。また、軸部３１３と係合可能な軸係合部３６１を有する軸係合部材３６０と、軸係合部材３６０を軸係合位置に向けて付勢する付勢手段としての弾性部材３５０とを別体に設けることにより、軸係合部３６１の面積を大きくすることができるため、軸部３１３を中心軸とした前枠２の揺動をより円滑に行うことができる。
【０１１２】
軸係合部材３６０の上端部には、飾り部材３４０におけるピン孔３４６の径より僅かに小さい径を有する係合ピン部３６２が上方へ突出して形成されており、ピン孔３４６を上下に通過するようになっている。これにより、軸係合部材３６０の上端部に位置する係合ピン部３６２がピン孔３４６内において前後左右方向への移動が規制されるため、軸係合部材３６０を安定して上下移動させることができる。
【０１１３】
なお、飾り部材３４０のピン孔３４６の深さは、軸係合部材３６０が軸係合位置に位置するときには係合ピン部３６２がピン孔３４６内に位置し、軸係合部材３６０が非軸係合位置に位置するときには係合ピン部３６２がピン孔３４６（飾り部材３４０）から上方へ突出する深さとなっている。これにより、軸係合部材３６０が非軸係合位置に位置する状態を目視で確認することができるため、軸係合部材３６０が非軸係合位置に位置したまま放置されることを防止することができる。
【０１１４】
また、本実施形態において、図１８の二点鎖線で示すように、軸係合部材３６０の軸係合部３６１が軸部３１３と係合した状態で、キャップ部材３７０を飾り部材３４０のピン孔３４６に圧入取付して軸係合部材３６０の上方を覆うようにしてもよい。なお、このキャップ部材３７０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る。
【０１１５】
このようにすれば、軸係合部３６１と軸部３１３との係合状態を解除するには、キャップ部材３７０をピン孔３４６から取り外す必要があるが、キャップ部材３７０はピン孔３４６に圧入取付されているため、キャップ部材３７０を変形させるようにしてピン孔３４６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３７０では、シワやひび割れといったキャップ部材３７０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３７０をピン孔３４６から取り外して軸係合部３６１と軸部３１３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３７０がピン孔３４６に取り付けられた状態）に戻したとしても、キャップ部材３７０あるいは飾り部材３４０におけるキャップ部材３７０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。
【０１１６】
すなわち、キャップ部材３７０は不正操作識別手段および移動規制手段としての機能を有しており、このキャップ部材３７０により、軸係合部材３６０の軸係合部３６１と軸部３１３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や軸係合部材３６０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３１３や軸係合部材３６０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。
【０１１７】
さらに不正操作識別手段として、封印シールを飾り部材の上面側に貼り付けてピン孔３４６の上部を塞ぐようにしてもよい。さらに、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。また、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。また移動規制手段として、図２４に示すような弾性部材（図２４における軸係合部材１５０）の上方への曲げ変形を規制可能なロック機構を別体に設けてもよい（詳細は前述）。
【０１１８】
さて、軸係合部材３６０における係合ピン部３６２の基端部には、係合溝部３６３が形成されており、弾性部材３５０のピン係合口３５３と係合するように構成されている。これにより、軸係合部材３６０は、飾り部材３４０の軸係合部材取付部３４５において、弾性部材３５０により軸係合位置に向けて付勢された状態で、軸部３１３が軸孔３３２に位置するときに軸係合部３６１が軸部３１３と係合可能な軸係合位置と、軸係合部３６１と軸部３１３との係合を解除する非軸係合位置とに変位（上下移動）可能となる。
【０１１９】
軸係合部材３６０の下面側には、軸係合部３６１に繋がって後方へ水平に延びる第１軸当接部３６４と、第１軸当接部３６４に繋がって上斜め後方に延びる第２軸当接部３６５とが形成されており、図１９（ａ）の二点鎖線に示すように、枠上部揺動金具３１０の軸部３１３が第２固定側板状部３３１におけるガイド孔３３３の後端部付近に位置するときに第２軸当接部３６５に当接し、図１９（ｂ）に示すように、軸部３１３がガイド孔３３３の中央部から前端部付近に位置するときに第１軸当接部３６４に当接するようになっている。すなわち、軸部３１３がガイド孔３３３内に導入されて前方に移動するときに第２軸当接部３５５と第１軸当接部３５４との順で当接し、軸係合部材３６０が軸部３１３に押圧されて上方へ移動する。
【０１２０】
このとき、弾性部材３５０のピン係合口３５３と軸係合部材３６０の係合溝部３６３とが係合しているため、軸係合部材３６０が上方へ移動するときに係合溝部３６３の下側部が弾性部材３５０の他端部下面側に当接し、軸係合部材３６０が上方へ移動して非軸係合位置に位置すると、弾性部材３５０の他端部（係合部）が軸係合部材３６０に押圧されて、弾性部材３５０が上方へ曲げられるように弾性変形するようになっている。
【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】
そして、前枠２を直立方向に傾動させると、軸部３１３は第２固定側板状部３３１（壁部３３５）の後方からガイド孔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。
【０１２３】
このとき、図１９（ａ），（ｂ）の順に示すように、軸部３１３がガイド孔３３３内に導入されて前方に移動するときに軸係合部材３６０の第２軸当接部３５５と第１軸当接部３５４とに順に当接し、軸係合部材３６０が軸部３１３に押圧されて上方へ移動し非軸係合位置に変位するとともに、軸係合部材３６０の係合溝部３６３と係合した弾性部材３５０の他端部（ピン係合口３５３）が軸係合部材３６０に押圧されて、弾性部材３５０が上方へ曲げられるように弾性変形する。
【０１２４】
そして、図１７および図１８に示すように、軸部３１３が軸孔３３２に位置すると、弾性部材３５０の付勢力を受けて軸係合部材３６０が（下方へ移動し）軸係合位置に変位して軸係合部材３６０の軸係合部３６１が軸部３１３と係合し、この状態で軸部３１３が軸孔３３２内に保持される。このようにして、軸係合部材３６０の軸係合部３６１により軸部３１３のガイド孔３３３への移動が規制された状態で３１３軸部が軸孔３３２と係合するため、前枠２を上動させることなく容易に枠上部揺動金具３１０と枠上部固定金具３２０とをヒンジ接続させることができ、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。
【０１２５】
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、前述したように、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。
【０１２６】
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、軸係合部材３６０を上方へ移動させて軸係合部材３６０の軸係合部３６１と枠上部揺動金具３１０の軸部３１３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。
【０１２７】
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がガイド孔３３３内に導入されてガイド孔３３３に沿って前方へ移動すると軸係合部材３６０が軸部３１３に押圧されて非軸係合位置へ変位し、軸部３１３が軸孔３３２に位置すると軸係合部材３６０（軸係合部３６１）が弾性部材３５０の付勢力を受けて（弾性力を利用して）軸係合位置へ変位し軸部３１３と係合することで、軸係合部材３６０により軸部３１３のガイド孔３３３への移動が規制された状態で軸部３１３が軸孔３３２と係合するため、前枠２を上動させることなく容易に枠上部揺動金具３１０と枠上部固定金具３２０とをヒンジ接続させることができ、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。
【０１２８】
また、軸係合部３６１が軸部３１３の形状に合わせた円弧状に形成されているため、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と係合可能な軸係合部３６１を有する軸係合部材３６０と、軸係合部材３６０を軸係合位置に向けて付勢する付勢手段としての弾性部材３５０とを別体に設けることにより、軸係合部３６１の面積を大きくすることができるため、軸部３１３を中心軸とした前枠２の揺動をより円滑に行うことができる。また、軸係合部材３６０（軸係合部３６１）が上下変位して軸部３１３と係合するため、軸係合部材を水平変位させる場合に比べて軸係合部３６１を軸部３１３の後側方により広く接触させることができ、軸係合部軸部３１３との係合による効果が得られやすい。
【０１２９】
さらに、ガイド部材３４０により、第１固定側板状部３２５の逃げ孔３２７や、第２固定側板状部３３１の軸孔３３２およびガイド孔３３３、また、枠上部揺動金具３１０の軸部３１３や、弾性部材３５０および軸係合部材３６０が外部から見て飾り部材３４０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や弾性部材３５０等に対する不正行為の抑止が期待できる。
【０１３０】
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２０〜図２２を参照して説明する。ここで、図２０は開放保持機構４００の側面図、図２１は開放保持機構４００の分解斜視図、そして図２２は開放保持機構４００の平面図である。
【０１３１】
開放保持機構４００は、図２１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。
【０１３２】
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。
【０１３３】
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。
【０１３４】
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。
【０１３５】
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。
【０１３６】
収容部材板状部４２２の右方（図２１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２１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。
【０１３７】
収容部材板状部４２２の左端（図２１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２１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。
【０１３８】
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。
【０１３９】
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。

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。
【０１４１】
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２０および図２２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。
【０１４２】
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２１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。
【０１４３】
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２２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。
【０１４４】
そして、ガラス扉５を前枠２に対して所定開放保持角度まで開放揺動させるとともに、収容部材係合軸部４１１をスライド係合孔４２３の左端（図２１における右端）までスライド移動させて開放保持係止孔４２４に係止させる。そうすると、図２０および図２２に示すように、開放支持部材４１０によりガラス扉５が前枠２に対して開放支持され、この結果、所定開放保持角度においてガラス扉５が前枠２に対して開放保持される。
【０１４５】
これにより、前枠２の収容枠２ａに複数のレバーＬ１，…を利用してセット保持された遊技盤１０の着脱作業をスムーズに行うことができ、さらに、遊技盤１０の前面側におけるメンテナンス作業をスムーズに行うことができる。なお、ガラス扉５が前枠２に対して開放保持された状態から、開放支持部材４１０を収容部材４２０に収容するには、前述と逆の作業を行えばよい。
【０１４６】
このため、以上のような構成の開放保持機構４００によれば、開放支持部材４１０により、所定開放保持角度においてガラス扉５が前枠２に対して開放保持されるため、遊技盤１０の着脱作業や、遊技盤１０の前面側におけるメンテナンス作業をスムーズに行うことができる。
【０１４７】
また、上述の各実施形態において、枠上部ヒンジ機構がパチンコ機ＰＭに設けられているが、これに限られるものではなく、例えば、スロットマシン等、ベース部材と、ベース部材に揺動開閉自在にヒンジ接続される開閉部材とを備えた遊技機に設けられていればよい。
【０１４８】
さらに、上述の各実施形態において、枠上部ヒンジ機構がパチンコ機ＰＭの左上部に設けられるともに、枠下部ヒンジ機構がパチンコ機ＰＭの左下部に設けられているが、枠下部ヒンジ機構がパチンコ機ＰＭの左上部に設けられるともに、枠上部ヒンジ機構がパチンコ機ＰＭの左下部に設けられてもよい。

【発明の効果】
以上説明したように、本発明による遊技機のヒンジ機構によれば、軸部がガイド孔内に導入されてガイド孔に沿って前方へ移動すると軸係合部材が軸部に押圧されて非軸係合位置へ変位し、軸部が軸孔に位置すると軸係合部材が弾性部材の付勢力を受けて軸係合位置へ変位し軸部と係合することで、軸係合部材により軸部のガイド孔への移動が規制された状態で軸部が軸孔と係合するため、開閉部材を上動させることなく第１ヒンジ部材と第２ヒンジ部材とをヒンジ接続させることができ、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。

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. 24A, the upper and lower hinge mechanisms are horizontally disposed with a first hinge member 500 in which a shaft support hole 502 is formed in a first plate-like portion 501 disposed horizontally. And a second hinge member 505 to which a support shaft 507 protruding upward from the second plate-like portion 506 is fixed. 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 position of the center of gravity, the mounting operation for positioning the upper and lower two places by moving the front frame upward is performed. There was a problem that it was extremely difficult.
[0005]
In view of such a problem, for example, as shown in FIG. 24B, an introduction opening 503 that is 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 The left and right sides of the support shaft 507 of the hinge member 505 ′ are cut into a flat shape to form flat portions 507 a and 507 a so that the width of the left and right flat portions 507 a and 507 a of the support shaft 507 is slightly narrower than the width of the introduction opening 503. It is known to configure.
[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]

[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.
[0009]
The present invention has been made in view of such problems, and it is possible to easily attach an opening / closing member such as a front frame to a base member such as an outer frame. It is an object of the present invention to provide a hinge mechanism for a gaming machine configured to be able to hold an opening / closing member firmly without being disengaged from a base member regardless of a swinging position.
