【発明の属する技術分野】
本発明は、パチンコ機またはスロットマシンなどの遊技機に用いられる制御装置であって、コネクタや電気部品の実装された制御基板がケースベースとケースカバーとからなるケースの内部空間に格納された後に、ケースベースとケースカバーとが互いに開封不能に封緘される制御装置に関する。
【０００２】
【従来の技術】
従来の遊技機の制御装置は、遊技制御基板を保持するボックス基体に蓋体を被せ、蓋体をボックス基体に対し一方向に摺接することで、蓋体の摺接方向先端側に突起として形成された係合部とボックス基体に穴として形成された係合部とを互いに嵌め込む一方、蓋体の摺接方向後端側に設けられた複数の固定個所部を有する基体側結合部とボックス基体に設けられた複数の固着具を収納した固定個所部を有する蓋体側結合部とを互いに向かい合わせ、ボックス基体と蓋体とから形成される内部空間に上記ボックス基体に装着された回路基板を格納し、基体側結合部における１つの固着具が蓋体側結合部における１つの固定個所部に結合されることで、ボックス基体と蓋体とを開封不能に封緘する一方、このボックス基体と蓋体との封緘下で上記１つの固定個所部に結合された固着具の周囲をボックス側結合部から切り離すことで、ボックス基体と蓋体とが開封可能になっている（例えば、特許文献１参照）。

【０００４】
【発明が解決しようとする課題】
しかしながら、従来例は、固着具が遊技機の制御装置を取り付けるための相手側部材の側に配置されるボックス基体に設けられた構造である。このため、制御装置が遊技機に取り付けられた場合、固着具の頭部である操作部分が制御装置と相手側部材との間に配置される。よって、公的機関が制御装置の検査を行う場合、制御装置が遊技機に取り付けられた状態において、検査を行う作業者が遊技機の裏側の制御装置を見ただけでは、どの固着部がボックス基体と蓋体とを開封不能に封緘しているかを確認することができない。そのようなことから、固着具の使用が適正であるか否かを確認するにも、制御装置を相手側部材から取り外して、ボックス基体と蓋体とを開封不能に封緘している固着具の使用が適正か不適正かを確認しなければならず、公的機関の検査に多大な労力と時間がかかり、にわかに採用しがたいという問題点があった。
【０００５】
そこで、本発明は、制御装置が遊技機の相手側部材に取り付けられた状態において、遊技機の裏側の制御装置を見ただけで、ケースカバーとケースベースとを開封不能に封緘している固着具を容易に確認することができる遊技機の制御装置を提供するものである。
【０００６】
【課題を解決するための手段】
本発明にあっては、裏側に開放された四角な箱形のケースベースには複数の固定個所部を有するベース側結合部とベース側摺接係合部とが設けられ、前側に開放された四角な箱形のケースカバーには複数の固着具を収納した固定個所部を有するカバー側結合部とカバー側摺接係合部とが設けられ、コネクタおよび電気部品の実装された方形な制御基板がケースカバーに装着され、ベース側摺接係合部とカバー側摺接係合部とが互いに摺接係合で嵌め合わされることで、ケースベースとケースカバーとからなるケースの内部空間に前記ケースカバーに装着された方形な制御基板を格納する遊技機の制御装置において、前記ケースベースの内部空間側の内面にはベース側摺接係合部とカバー側摺接係合部とによる摺接係合の嵌め合わせ方向に内部空間を２分する隔壁が設けられ、前記ベース側結合部と前記ベース側摺接係合部とが隔壁で２分された内部空間に対し個別に設けられ、前記ケースカバーが隔壁で２分された内部空間に対する２個であって、前記２個のケースカバーがカバー側結合部とカバー側摺接係合部とを個別に備え、１個のケースベースと前記２個のケースカバーとからなる２個の内部空間に前記制御基板を個別に格納し、前記ベース側結合部と前記カバー側結合部とが前記ベース側摺接係合部と前記カバー側摺接係合部とによる摺接係合の嵌め合わせ方向と直交する方向の一側に位置してケースベースとケースカバーとに個別に設けられ、前記カバー側結合部における１つの固着具が前記ベース側結合部における１つの固定個所部に結合されることで、前記ケースベースと前記ケースカバーとを開封不能に封緘し、このケースベースと前記ケースカバーとの封緘下で前記１つの固定個所部に結合された固着具の周囲がカバー側結合部から切り離されることによって、前記ケースベースと前記ケースカバーとが開封可能となることによって、組み立てられた制御装置が相手側部材に取り付けられる場合、ケースベースの前面を相手側部材の裏面と対向させる格好で、相手側部材に制御装置を取り付ければ、作業者が遊技機の制御装置を見た場合にカバー側結合部とベース側結合部とを視認することができるので、どの固定個所部の固定ねじがケースベースとケースカバーとを開封不能に封緘しているかを容易に確認することができる。
また、ケースベースの内部空間側の内面にはベース側摺接係合部とカバー側摺接係合部とによる摺接係合の嵌め合わせ方向に内部空間を２分する隔壁が設けられ、ベース側結合部とベース側摺接係合部とが隔壁で２分された内部空間に対し個別に設けられ、ケースカバーが隔壁で２分された内部空間に対する２個であって、これら２個のケースカバーがカバー側結合部とカバー側摺接係合部とを個別に備え、１個のケースベースと２個のケースカバーとからなる２個の内部空間に方形な制御基板が個別に格納されるので、制御装置を構成する部品点数を少なくすることができるとともに制御装置の設置スペースを小さくすることができる。
また、本発明にあっては、ケースカバーの内部空間側の内面には制御基板に形成された複数の取付孔に嵌め込まれる基板取付部が形成され、止ねじのような固着具を用いることなく、制御基板がケースカバーに取り付けられるので、制御装置の組み立ておよび分解の作業を容易に行うことができる。
また、本発明にあっては、隔壁がカバー側挿入係合部を備えれば、複数のケースカバーの周縁前部がケースベースと嵌まり合うので、２個のケースカバーを１個のケースベースに嵌め合わせた姿勢を安定にすることができる。

【０００８】
図１を参照し、遊技機の制御装置Ａについて説明する。制御装置Ａは、制御基板１がケースベース２とケースカバー３とからなるケース４の内部空間に格納された形態であって、例えば、遊技機の制御装置Ａを取り付けるための相手側部材Ｂとして遊技盤Ｃの裏面に配置された部品取付具の裏面に取り付けられる。この相手側部材Ｂは、部品取付具以外に、遊技盤Ｃを収納する遊技機枠の図外のリアプレートや裏機構板などでもよい。
【０００９】
図２を参照し、制御装置Ａの構成部品について説明する。制御基板１は、方形なプリント基板のような回路基板の前面にコネクタ５や図外の制御に必要な電気部品を実装し、回路基板の四隅に回路基板の前後方向に貫通する取付孔６を備える。コネクタ５は、回路基板の一側部例えば上縁部に左右方向に横一列に配置される。回路基板に対しコネクタ５と同じ側の表面に実装される電気部品Ｄ（図１０参照）には、ＣＰＵとＲＯＭとＲＡＭからなるマイクロコンピュータ、入出力インターフェース、バックアップ電源などがある。
【００１０】
ケースベース２は、光透過性の有る無色な合成樹脂により、裏側および左側に開放された四角な箱形である。ケースベース２の方形な基壁７には、上下壁８；９が基壁７の上下縁より裏側に突出し、一側壁１１が基壁７の例えば右側縁より裏側に突出する。上下壁８；９と一側壁１１とは、互いに連接される。上下壁８；９よりも内側に配置された上下支持壁１２；１３が、基壁７より裏側に突出する。制御装置Ａが図１の相手側部材Ｂである部品取付具に取り付けられる場合、基壁７の前面が相手側部材Ｂの裏面と対向する。上下支持壁１２；１３は、制御基板１の裏面を受け止める部分である。上下支持壁１２；１３の基壁７からの高さは、上下壁８；９の基壁７からの高さよりも低い。
【００１１】
上下壁８；９と上下支持壁１２；１３との間に位置する基壁７より裏側の隙間は、ケースカバー３の上下縁部を収納する上下取込溝１４；１５を形成する。上下取込溝１４；１５はケースベース２の裏側および左側に開放する。上下取込溝１４；１５の右端は一側壁１１で閉鎖される。一側壁１１には、複数の係合孔として形成されたベース側挿入係合部１６が設けられる。一側壁１１の反対側に位置する基壁７の左側縁には、複数の係合突起として形成されたベース側挿入係合部１７が設けられる。
【００１２】
上下壁８；９に個別に設けられた上下ベース側摺接係合部１８；１９は、上下壁８；９の裏面より上下支持壁１２；１３の方向である内側に向けて基壁７の裏面と平行に突出し、上下取込溝１４；１５に収納されたケースカバー３の上下縁部を裏側から覆う部分である。上下支持壁１２；１３の左右端部側には、基壁７から突出した基板仮止部２１を備える。基板仮止部２１の基壁７からの高さは、上下支持壁１２；１３の基壁７からの高さと同じである。
【００１３】
基板仮止部２１には、仮止穴２２が設けられる。仮止穴２２は、基板仮止部２１の端面より内部に窪み、基壁７の前面に貫通していない。仮止穴２２は、公的機関がケース４を開いて制御基板１の検査を行う場合、制御基板１をケースカバー３に取り付ける止ねじ６５（図１６参照）を締結するために使用する穴である。ケースベース２には、ベース側結合部２３が設けられる。ベース側結合部２３は、上下ベース側摺接係合部１８；１９と上下カバー側摺接係合部３４；３５とによる摺接係合の嵌め合わせ方向と直交する方向の一側、例えば、下壁９に設けられる。ベース側結合部２３は、下壁９より外側に突出する。ケースベース２における上下壁８；９の左端部には、孔または凹部または溝に形成されたベース側ロック６６を備える。ベース側ロック６６は、上下壁８；９に設けたが、上下壁８；９のいずれか一方だけでもよい。
【００１４】
図４にも示すように、ケースカバー３は、光透過性の有る無色な合成樹脂により、前側に開放された四角な箱形である。ケースカバー３は、制御基板１の図外の電気部品を配置する前側に開放された横長な部品配置室２５を備える。部品配置室２５の周囲には、裏壁２６が部品配置室２５の周縁部より横方向に突出する。裏壁２６の周囲には、周壁２７が裏壁２６より前側に突出する。裏壁２６と周壁２７とが、制御基板１の回路基板を収納する前側に開放された基板収納室２８を形成する。部品配置室２５と基板収納室２８とは、相互に連なる前側に開放された１つの空間を形成する。基板収納室２８の四隅には、制御基板１の取付孔６に挿入される突起として形成された基板取付部２９が裏壁２６より前側に突出する。基板収納室２８の上部には、制御基板１のコネクタ５を取り込むコネクタ逃孔３０が設けられる。
【００１５】
ケースカバー３の図２における右側の周壁２７（図４では左側の周壁２７に相当する）には、基板仮止部２１を逃げる切欠部３１と、複数の係合突起として形成されたカバー側挿入係合部３２とが、設けられる。この係合突起たるカバー側挿入係合部３２は、前記係合孔たるベース側挿入係合部１６と対応する位置で、上記右側の周壁２７より外側に突出する。ケースカバー３の図２における左側の周壁２７（図４では右側の周壁２７に相当する）には、複数の係合孔として形成されたカバー側挿入係合部３３が、前記係合突起たるベース側挿入係合部１７と対応する位置に設けられる。ケースカバー３では、上下の周壁２７および上下の裏壁２６が上下カバー側摺接係合部３４；３５を形成する。ケースカバー３にはカバー側結合部３６が設けられる。カバー側結合部３６は、ベース側結合部２３と対応するケースカバー３の下側の周壁２７に設けられる。カバー側結合部３６は、周壁２７より外側に突出する。ケースカバー３における上下の周壁２７の左端部には、突起に形成されたカバー側ロック６７を備える。カバー側ロック６７は、上下の周壁２７に設けたが、上下の周壁２７のいずれか一方だけでもよい。その場合、カバー側ロック６７とベース側ロック６６は、互いに嵌め合わされるものであるので、同じ側に設けられる。また、カバー側ロック６７を孔または凹部または溝に形成し、ベース側ロック６６を突起に形成してもよい。
【００１６】
図３を参照し、ベース側結合部２３とカバー側結合部３６と固定ねじ５５との構造について説明する。ベース側結合部２３は、ケースベース２の下壁９より下方に突出した平坦なブロックベース３７、ブロックベース３７の周囲より裏側に突出された周壁３８、ブロックベース３７の前面より前側に円筒状に膨出された複数の固定個所部３９を備える。これらの固定個所部３９は図５にも示すように筒状の内部孔４０の前側が閉鎖された行止まり形状である。ベース側結合部２３には、ワッシャー４１とワッシャーカバー４２とが設けられる。ワッシャー４１は、ワッシャーカバー４２よりもひとまわり小さな形状である。ワッシャー４１は、周壁３８で囲まれた内側に取り込まれてブロックベース３７に接触するステンレスからなる板状であって、固定個所部３９と同数の開口部４３を内部孔４０と同軸に備える。開口部４３には、開口部４３の周縁より開口部４３の中心に向かって突出する複数の突起４４を備える。これらの突起４４は開口部４３の周縁より開口部４３の中心に行くにしたがって徐々に前側に傾斜する。
【００１７】
ワッシャーカバー４２は、周壁３８で囲まれた内側に取り込まれてブロックベース３７に接触する光透過性の有る無色な合成樹脂からなる板状であって、固定個所部３９と同数の貫通孔４５を内部孔４０と同軸に備える。貫通孔４５は、開口部４３より小さい直径を有する。そして、ワッシャー４１の開口部４３が内部孔４０と同軸となるように、ワッシャー４１がブロックベース３７に搭載され、ワッシャーカバー４２がワッシャー４１を全体的に覆うようにベース側結合部２３のブロックベース３７に搭載された後、ワッシャー４１よりはみ出たワッシャーカバー４２の周縁部が超音波振動または接着剤でブロックベース３７に接合される。これによって、図５にも示すようにワッシャー４１の突起４４の先端部がワッシャーカバー４２の貫通孔４５より内側に突出し、ワッシャーカバー４２が、ワッシャー４１のベース側結合部２３からの脱落防止を図る。
【００１８】
カバー側結合部３６は、ケースカバー３の周壁２７より外側に突出したブロックベース４６と、ブロックベース４６より下側に配置された複数の筒状の固定個所部４７と、各固定個所部４７とブロックベース４６とを連結する第１連結片４８と、各固定個所部４７の相互を連結する第２連結片４９とを備える。固定個所部４７は、裏側の大孔部５１と、図５に示す前側の小孔部５２とを有する。大孔部５１の孔径はタッピングねじのような固定ねじ５５のねじ部５６および頭部５７が直線的に挿入し得る大きさである。小孔部５２の孔径は固定ねじ５５のねじ部５６の先端部が回転可能に係合し得る大きさである。カバー側結合部３６の固定個所部４７は、ベース側結合部２３の固定個所部３９と位置が対応する。カバー側結合部３６には、固定ねじ５５とねじカバー５９とが設けられる。
【００１９】
固定ねじ５５は、カバー側結合部３６の固定個所部４７と同数の個数である。固定ねじ５５は、雄ねじが外周面に形成されたタッピングねじのようなねじ部５６、ねじ部５６より大きな頭部５７、ねじ部５６と頭部５７との間に形成されたくびれ部６１を備える。ねじ部５６はくびれ部６１より先端側に行くにしたがって徐々に細くなる。ねじ部５６の雄ねじのくびれ部６１側終端の螺旋は閉鎖され、ねじ部５６とくびれ部６１との境を形成する。ねじカバー５９は、固定個所部４７および第２連結片４９を覆うように、光透過性の有る無色な合成樹脂からなる板状であって、十字形のスロット６２を固定個所部４７と同軸に備える。
【００２０】
そして、固定ねじ５５のねじ部５６がカバー側結合部３６における固定個所部４７の大孔部５１を経由して小孔部５２に挿入され、固定ねじ５５の頭部５７が大孔部５１に挿入される。このように固定ねじ５５が固定個所部４７に個別に挿入された場合、ねじ部５６の先端が小孔部５２より前側に突出しないか、または、突出しても図５に示すようにベース側結合部２３と干渉しないように僅かに突出される。つまり、ケースベース２とケースカバー３とが摺接係合される場合にねじ部５６の先端がベース側結合部２３のワッシャーカバー４２および周壁３８と接触しないようになっている。このようにして、全部の固定ねじ５５がカバー側結合部３６の固定個所部４７に個別に格納される。その後、ねじカバー５９が固定個所部４７および第２連結片４９を覆うようにカバー側結合部３６のブロックベース４６に搭載された後、ブロックベース４６に超音波振動または接着剤等で接合される。これによって、ねじカバー５９が、固定ねじ５５のカバー側結合部３６からの脱落防止を図る。
【００２１】
図２、図６−図１１を参照し、制御装置Ａの組み立て方について説明する。図２に示すように、コネクタ５や図外の電気部品の実装された制御基板１が、固定ねじ５５およびねじカバー５９をカバー側結合部３６に取り付けたケースカバー３に、装着される。この場合、制御基板１のコネクタ５や電気部品が裏側の開放された部分を上に向けた格好のケースカバー３に挿入され、コネクタ５がコネクタ逃孔３０を経由してケースカバー３の裏壁２６より外側に突出し、電気部品が部品配置室２５に取り込まれる。そして、図６に示すように、制御基板１の取付孔６がケースカバー３の基板取付部２９に嵌め込まれる。これによって、図１０に示すように、制御基板１における回路基板の周縁部のコネクタ５を搭載した側の面が基板収納室２８の裏壁２６に接触し搭載される。つまり、制御基板１の取付孔６とケースカバー３の基板取付部２９とが互いに嵌め込まれることで、止ねじのような固着具を用いることなく、制御基板１がケースカバー３に取り付けられるので、制御装置Ａの組み立ておよび分解の作業が容易である。
【００２２】
次に、図７に示すように、ケースベース２が、裏側に開放された部分を下に向けた格好で、ケースカバー３の前側に開放された部分に向かい合わされ、ケースカバー３の右側部分とケースベース２の左側部分とが互いに近づけられる。そして、ケースカバー３の切欠部３１がケースベース２の左側に位置する上下支持壁１２；１３および左側に位置する基板仮止部２１を取り込むように、ケースカバー３の上下側に位置する周壁２７とケースベース２の上下取込溝１４；１５とが互いに嵌め合わされる。この場合、制御基板１の右側部前面が上下支持壁１２；１３で受け止められる。
【００２３】
その後、図８に示すように、ケースベース２とケースカバー３とが互いに合わせられたまま、ケースベース２が左側に向けて横移動され、ケースカバー３が右側に向けて横移動される。これらの横移動はいずれか一方だけもよい。このケースベース２とケースカバー３との相対的な横移動に伴い、ケースベース２の上下取込溝１４；１５とケースカバー３の上下側に位置する周壁２７との摺接係合に伴う嵌め合いが増加する。それに伴い、上下ベース側摺接係合部１８；１９が上下カバー側摺接係合部３４；３５の裏側に位置しつつ上下カバー側摺接係合部３４；３５を通過する。これによって、上下ベース側摺接係合部１８；１９と上下カバー側摺接係合部３４；３５とが互いに摺接係合で前後方向（前側と裏側との方向）に抜けないように嵌め合わされ、ケースベース２とケースカバー３とが互いに前後方向に分離不能となる。
【００２４】
引き続き、図９に示すように、ケースベース２とケースカバー３との相対的な横移動が進行するのに伴い、ベース側挿入係合部１６；１７とカバー側挿入係合部３２；３３とが互いに嵌め合わされる。これによって、ケースベース２とケースカバー３とが互いにそれらの周縁の全部において前後方向に分離不能となる。そして、ケースベース２の一側壁１１の内側面とケースカバー３における右側の周壁２７の外側面とが互いに突き当てられる直前において、図２のベース側ロック６６とカバー側ロック６７とが互いに嵌め合わされる。これによって、ケースベース２とケースカバー３とが上記摺接係合の嵌め合わせ方向である矢印Ｘ１方向の逆方向に横移動することがないので、ケースベース２とケースカバー３との不意の分離を防止することができる。その後、ケースベース２の一側壁１１の内側面とケースカバー３における右側の周壁２７の外側面とが互いに突き当てられることで、ベース側結合部２３とカバー側結合部３６とが互いに前後方向で向かい合わされる。
【００２５】
第１実施形態では、図２に示すように、ケースベース２の上下取込溝１４；１５が左側に開放されており、ケースカバー３の周壁２７の右側の上下には切欠部３１が形成されているので、ケースベース２とケースカバー３とを組み合わせる場合、ケースベース２とケースカバー３とを互いに前後方向に重なり合う量が多くなるように左右方向の一側から他側に向けて横移動すればよい。つまり、図７−図９より明らかなように、ケースベース２の左側部と制御基板１を嵌め込んだケースカバー３の右側部とが互いに前後方向で嵌め合わされた後、ケースベース２だけが左側に移動するか、または、ケースカバー３だけが右側に移動するか、または、双方が移動するかのいずれかによって、ケースベース２とケースカバー３とが互いに前後方向に重なり合う量が多くなるように左右方向の一側から他側に向けて横移動するに伴い、上下ベース側摺接係合部１８；１９と上下カバー側摺接係合部３４；３５とが互いに嵌め合わされ、ベース側挿入係合部１６とカバー側挿入係合部３２とが互いに嵌め合わされ、ベース側挿入係合部１７とカバー側挿入係合部３３とが互いに嵌め合わされ、ケースベース２とケースカバー３とが互いに前後方向に分離不能となる。したがって、制御装置Ａの組み立ておよび分解の作業が簡単である。
【００２６】
その状態において、図１０および図１１に示すように、例えば、作業者が、ドライバーのような締結工具の先端部を、上下ベース側摺接係合部１８；１９と上下カバー側摺接係合部３４；３５とが摺接係合の嵌め合わせ方向である矢印Ｘ１方向の先端側に位置するねじカバー５９のスロット６２から、当該スロット６２と対応するカバー側結合部３６における１つの固定個所部４７の内部に挿入し、当該固定個所部４７に格納された固定ねじ５５における頭部５７の工具溝に装着する。そのまま、作業者が締結工具を上下ベース側摺接係合部１８；１９の方向に押しながら固定ねじ５５の締結方向に回転操作する。
【００２７】
これによって、固定ねじ５５のねじ部５６がカバー側結合部３６の固定個所部４７からベース側結合部２３のワッシャーカバー４２における１つの貫通孔４５およびワッシャー４１の開口部４３を経由して固定個所部３９の１つの内部孔４０に締結される。この固定ねじ５５のねじ部５６がワッシャー４１の開口部４３における突起４４とねじ嵌合しつつ当該突起４４を前側に越える。それに伴い、突起４４が前側に傾斜したまま固定ねじ５５のねじ部５６からくびれ部６１に嵌め込まれる。
【００２８】
これによって、上記締結工具により固定ねじ５５が取り外し操作により締結時とは逆方向に回転されても、突起４４がくびれ部６１に存在したまま、固定ねじ５５が空回りするだけで、固定ねじ５５がカバー側結合部３６の固定個所部４７より取り外し不能となる。このように、１つの固定ねじ５５がカバー側結合部３６の１つの固定個所部４７とベース側結合部２３の１つの固定個所部３９との双方に結合していることで、ケースベース２とケースカバー３とが開封不能に封緘され、制御基板１がケース４の内部に密封された形態となる。
【００２９】
このように制御基板１をケース４の内部空間に格納した形態に組み立てられた制御装置Ａにあっては、図１０に示すように、コネクタ５の近傍における制御基板１の部分が上支持壁１２と上ベース側摺接係合部１８と裏壁２６とで前後方向から支持された格好なる。よって、コネクタ５に図外の相手側コネクタを接続したり、当該相手側コネクタをコネクタ５から外したりする場合、制御基板１のコネクタ５周りががたつかず、コネクタ５に対する相手側コネクタの抜き差しの作業を容易かつ適切に行うことができる。また、制御基板１の裏面とケースベース２における基壁７の前面との間には、上下支持壁１２；１３の高さによる隙間が形成される。この隙間は、制御基板１の裏面に実装されたコネクタ５や電気部品Ｄなどの電極や取付足などの制御基板１の前面より前側に突出して部分が基壁７に接触しないようにするための逃げとなる。この隙間に収納可能な図外の電気部品を制御基板１の前面に実装してもよい。
【００３０】
このように制御基板１をケース４の内部空間に格納した形態に組み立てられた制御装置Ａは、図１に示すように、ケースベース２における基壁７の前面が相手側部材Ｂの裏面と対向される格好で、相手側部材Ｂに、図外の取付手段で取り付けられる。このように制御装置Ａが相手側部材Ｂに取り付けられることによって、公的機関が制御装置Ａの検査を行う場合、検査を行う作業者が相手側部材Ｂに取り付けられた制御装置Ａを裏側から見ると、ケース４の内部空間における制御基板１の電気部品Ｄ（図１０参照）やケース４より突出するコネクタ５およびカバー側結合部３６やベース側結合部２３を、光透過性の有る合成樹脂製のケースカバー３を通して見ることができ、どの固定個所部３９；４７の固定ねじ５５（図１０参照）がケースベース２とケースカバー３とを開封不能に封緘しているかを容易に確認することができる。

図１２−図１６を参照し、前記矢印Ｘ１方向の先端側に位置する１つの固定ねじ５５で開封不能に組み立てられた制御装置Ａを、公共機関による検査のために、分解する場合について説明する。図１２に示すように、作業者が、ニッパーのような切断工具で、上記矢印Ｘ１方向の先端側に位置する１つの固定ねじ５５の存在するカバー側結合部３６の１つの固定個所部４７における第１連結片４８（図３参照）と第２連結片４９と第２連結片４９を覆うねじカバー５９の部分とを、切断する。これによって、カバー側結合部３６の１つの固定個所部４７とベース側結合部２３の１つの固定個所部３９との双方を結合している１つの固定ねじ５５と、当該固定ねじ５５と対応するねじカバー５９の１つのスロット６２の存在する部分とが、ベース側結合部２３に残存する形態となる。
【００３２】
次に、図１３および図１４に示すように、作業者が、ケースベース２とケースカバー３とを組み立て時とは逆方向である矢印Ｘ２方向に相対的に横移動する。これによって、前記矢印Ｘ１方向の先端側に位置する１つの固定ねじ５５とカバー側結合部３６の１つの固定個所部４７とねじカバー５９の１つのスロット６２の存在する部分とがベース側結合部２３に取り残されたまま、その他の複数の固定ねじ５５が個別に格納されたカバー側結合部３６における固定個所部４７はケースカバー３と一緒に矢印Ｘ２方向に移動する。
【００３３】
引き続き、作業者がケースベース２とケースカバー３とを矢印Ｘ２方向に相対的に横移動し、上下カバー側摺接係合部３４；３５がケースベース２における最も左側に位置する上下ベース側摺接係合部１８；１９から左側に位置をずらされることで、上下ベース側摺接係合部１８；１９と上下カバー側摺接係合部３４；３５との相互の摺接係合が解除され、上下ベース側摺接係合部１８；１９が上下カバー側摺接係合部３４；３５を裏側に抜けるように解放する。その後、作業者は、制御基板１がケースカバー３から脱落しないように注意をはらいつつ、ケースベース２とケースカバー３とを前後方向に引き離して開封する。そして、作業者は、制御基板１の回路パターンのような配線や電気部品に手を触れないように注意をはらいつつ、制御基板１の取付孔６とケースカバー３の基板取付部２９との嵌め合いを解除し、制御基板１をケースカバー３から取り出す。
【００３４】
更に、図１５に示すように、作業者が、ケースカバー３から取り出された制御基板１のコネクタ５の設けられていない側の面をケースベース２の裏側に開放された側から上下ベース側摺接係合部１８；１９を避けて上下支持壁１２；１３の裏面に搭載した後、矢印Ｘ１方向に制御基板１を横移動させ、制御基板１の取付孔６とケースカバー３の基板仮止部２１の仮止穴２２との位置が合ったならば、上記制御基板１の横移動を停止する。その状態において、図１６に示すように、作業者が制御装置Ａとは別に用意された検査用の止ねじ６５を制御基板１の取付孔６から仮止穴２２に締結する。これによって、制御基板１がコネクタ５や電気部品をケースベース２から裏側に向けた格好でケースベース２に固定される。したがって、作業者が、ケースベース２の基壁７（図１５参照）の前面を検査台の上に載せることで、制御基板１のコネクタ５や電気部品が作業者の側に向いた格好となり、作業者が制御基板１への検査を容易に行うことができる。
【００３５】
上記検査終了後、制御装置Ａを組み立てる場合は、作業者が、止ねじ６５を取り外し、制御基板１をケースベース２から取り外した後、図６−図１１に示す前記順序で制御基板１とケースベース２とケースカバー３とを組み立てる。この場合、図１２における第２連結片４９やねじカバー５９の切断された部分の左隣りに配置された１つの固定ねじ５５が、摺接係合の嵌め合わせ方向である矢印Ｘ１方向の先端側に位置する１つの固定ねじ５５として、カバー側結合部３６の１つの固定個所部４７からベース側結合部２３の１つの固定個所部３９に締結され、ケースベース２とケースカバー３とが開封不能に封緘される。つまり、固定個所部３９；４７が４個設けられているので、３回の開封による検査を行い、開封不能に封緘された制御装置Ａとして４回使用することができるが、固定個所部３９；４７の個数は４個に限定されるものではなく、１個または２個または３個または５個以上であってもよい。
【００３６】
図１７−図１９は第２実施形態である。図１７は制御装置Ａを分解して示す。図１８は組み立てられた制御装置Ａを摺接係合の嵌め合わせ方向に切断した断面を示す。図１９は組み立てられた制御装置Ａを摺接係合の嵌め合わせ方向と直交する方向に切断した断面を示す。図１７において、第２実施形態の制御装置Ａは、１個のケースベース２Ａの内部空間側の内面たる基壁７の裏面に隔壁７１が設けられる。隔壁７１は、上下ベース側摺接係合部１８；１９と上下カバー側摺接係合部３４；３５とによる摺接係合の嵌め合わせ方向に当該ケースベース２Ａの内部空間を２分する。
【００３７】
１個のケースベース２Ａは、第１実施形態の１個のケースベース２に相当するものである。ケースベース２Ａは、左右側部に側壁のない点が、また、上ベース側摺接係合部１８の基壁７からの裏側への突出量（高さ）Ｈ１と下ベース側摺接係合部１９の基壁７からの裏側への突出量（高さ）Ｈ２とが異なる点が、第１実施形態のケースベース２と異なる。第２実施形態の場合、上ベース側摺接係合部１８の基壁７からの裏側への高さＨ１は、下ベース側摺接係合部１９の基壁７からの裏側への高さＨ２よりも低い（Ｈ１＜Ｈ２）。ケースベース２Ａには、隔壁７１で２分された内部空間に対し、基壁７、上下壁８；９、上下支持壁１２；１３、上下取込溝１４；１５、ベース側挿入係合部１６；１７、上下ベース側摺接係合部１８；１９、基板仮止部２１、複数の固定個所部３９やワッシャー４１およびワッシャーカバー４２を有するベース側結合部２３、ベース側ロック６６が個別に設けられる。隔壁７１には、係合孔として形成されたベース側挿入係合部１７が形成される。ベース側挿入係合部１７は、ケースカバー３Ａ；３Ｂのそれぞれに係合突起として形成されたカバー側挿入係合部３２と嵌り合う部分である。
【００３８】
ケースカバー３Ａ；３Ｂはケースベース２Ａにおける隔壁７１で２分された内部空間に対する２個である。これら２個のケースカバー３Ａ；３Ｂは、第１実施形態のケースカバー３に相当するものである。ケースカバー３Ａがケースベース２Ａに対し左側から摺接係合するように嵌め合わされる点、ケースカバー３Ｂがケースベース２Ａに対し右側から摺接係合するように嵌め合わされる点が、また、上カバー側摺接係合部３４の前側の開放端からの裏側への突出量（高さ）Ｈ１と下カバー側摺接係合部３５の前側の開放端からの裏側への突出量（高さ）Ｈ２とが異なる点が、第１実施形態のケースカバー３と異なる。第２実施形態の場合、上カバー側摺接係合部３４の前側の開放端からの裏側への高さＨ１は、下カバー側摺接係合部３５の前側の開放端からの裏側への高さＨ２よりも低い（Ｈ１＜Ｈ２）。ケースカバー３Ａ；３Ｂには、部品配置室２５、裏壁２６、周壁２７、基板収納室２８、基板取付部２９、コネクタ逃孔３０、切欠部３１、カバー側挿入係合部３２；３３、上下カバー側摺接係合部３４；３５、複数の固定ねじ５５やねじカバー５９を有するカバー側結合部３６、カバー側ロック６７が個別に設けられる。１個のケースベース２Ａと２個のケースカバー３Ａ；３Ｂがケース４を形成する。
【００３９】
ケースベース２Ａとケースカバー３Ａ；３Ｂからなる２個の内部空間には、２個の方形な制御基板１Ａ；１Ｂが個別に格納される。制御基板１Ａ；１Ｂは、第１実施形態の制御基板１に相当するものであって、コネクタ５と取付孔６と電気部品Ｄとを個別に備える。制御基板１Ａ；１Ｂは、２個で１つの制御を協力して行うものであってもよいが、例えば、制御基板１Ａがパチンコ機の球を発射する機構を制御し、制御基板１Ｂがパチンコ機の賞球や貸球としての球を遊技者の側に払い出す機構を制御するというように、別々の制御を個別に行うものであってもよい。
【００４０】
第２実施形態によれば、１個のケースベース２Ａと２個の回路基板１Ａ；１Ｂと２個のケースカバー３Ａ；３Ｂとによって制御装置Ａを構成したので、別々に構成された複数の制御装置を用いる場合に比べ、制御装置Ａを構成する部品点数を少なくすることができるとともに制御装置Ａの設置スペースを小さくすることができる。前記Ｈ１＜Ｈ２の寸法の関係から、ケースベース２Ａに対するケースカバー３Ａとケースカバー３Ｂとの嵌め込み間違いを防止することができる。隔壁７１に形成されたベース側挿入係合部１７において、上から１つ目と上から３つ目とが例えばケースカバー３Ａのカバー側挿入係合部３２と嵌め合うものとして使用され、上から２つ目と上から４つ目とが例えばケースカバー３Ｂのカバー側挿入係合部３２と嵌め合うものとして使用されることによって、ケースカバー３Ａ；３Ｂのケースベース２Ａに対する上下方向の嵌まり合いの幅が大きくなり、ケースカバー３Ａ；３Ｂとケースベース２Ａとの嵌め合わせ姿勢が安定する。
