Description

【０００１】
【発明の属する技術分野】
この発明は、パチンコ機の遊技盤裏面に装備される制御基板収納ボックスのコネクタ部構造に関する。
【０００２】
【従来の技術】
従来、この種のパチンコ機における遊技盤の裏面に取付けられる制御基板収納ボックスにおいては、例えば制御基板を収納するケース体とこの制御基板に実装されるＲＯＭ、ＩＣ、ヒューズ等の実装部品を覆うカバー体とからなり、また、この制御基板には実装部品を覆うカバー体の外部位置には、例えば雄コネクタが複数箇所露出状に配設されて外部配線が雌コネクタを介して接続するようになっており、雄コネクタはプリント配線により実装部品と接続され、雄コネクタとカバー体との間にはプリント配線のプリントパターンの一部が露出する形態が取られている。
【０００３】
【発明が解決しようとする課題】
しかしながら、この従来の制御基板収納ボックスでは、雄コネクタとカバー体との間にプリント配線のプリントパターンの一部が露出する形態を取ることから、この露出されたプリントパターンを切断して、不正基板に接続する不正が行われる恐れのある問題がある。
本発明は、上記従来の問題点に鑑み、制御基板収納ボックスのコネクタ部に対する不正を防止することのできる制御基板収納ボックスのコネクタ部構造を提供することを目的とするものである。
【０００４】

前記ケース体には、当該ケース体の周囲に立ち上がる側壁が形成され、前記実装部品が実装される実装面を上向き状態で且つ前記各種のコネクタが当該ケース体の所定の側壁側に位置した状態で前記制御基板が収められるとともに、当該ケース体の側壁に複数の封印ボス部が切断可能な開封部を介してそれぞれ側方へ突出状に形成され、
前記カバー体は、前記各種のコネクタの配設部分に対応して前記ケース体の側壁よりも内側に所定間隔を隔てる凹壁部が形成されることにより、前記制御基板の各種のコネクタの配設部分を除いて覆うとともに、前記複数の封印ボス部のそれぞれに対応して封印締着部が切断可能な開封部を介して側方へ突出状に形成され、
前記凹壁部の下端部には、その下端部から前記ケース体の側壁にわたって延び且つ前記制御基板の各種のコネクタの配設部分を覆うために単数または複数のコネクタが挿通される窓部が貫設される遮蔽部材が一体形成され、
前記窓部の孔縁と、前記各種のコネクタとの間の間隔は、前記制御基板のプリント配線に対して不正部品の接続を不能とする僅かな間隔に設定されることで、前記プリント配線を保護する構成にしてあるとともに、前記複数の封印締着部と前記複数の封印ボス部のうちから１つの封印締着部と封印ボス部とを封印締着部材で封印することで、前記ケース体と前記カバー対とを取り外し不能に封印し、その封印した状態で前記開封部を切断することにより前記ケース体と前記カバー体とを取り外し可能とし、再度次の封印締着部と封印ボス部とを封印締着部材で封印することで、前記ケース体と前記カバー対とを取り外し不能に封印したことを特徴とする。
請求項２の発明は、ケース体とこれに取り付けられるカバー体を備えて、前記ケース体に納められる制御基板の実装面に実装部品が装備されて、この実装部品は前記カバー体により覆設されるとともに、このカバー体の外側の実装面には前記実装部品にプリント配線により所定のプリントパターンが露出されて接続された各種のコネクタが配設された制御基板収納ボックスであって、
前記ケース体には、当該ケース体の周囲に立ち上がる側壁が形成され、前記実装部品が実装される実装面を上向き状態で且つ前記各種のコネクタが当該ケース体の所定の側壁側に位置した状態で前記制御基板が収められるとともに、当該ケース体の側壁に複数の封印ボス部が切断可能な開封部を介してそれぞれ側方へ突出状に形成され、
前記カバー体は、前記各種のコネクタの配設部分に対応して前記ケース体の側壁よりも内側に所定間隔を隔てる凹壁部が形成されることにより、前記制御基板の各種のコネクタの配設部分を除いて覆うとともに、前記複数の封印ボス部のそれぞれに対応して封印締着部が切断可能な開封部を介して側方へ突出状に形成され、
前記カバー体の凹壁部の下端部と前記ケース体の側壁にわたって、前記カバー体とは別部材で形成され且つ前記制御基板の各種のコネクタの配設部分を覆うために単数または複数のコネクタが挿通される窓部が貫設される遮蔽部材が設けられるとともに、該遮蔽部材の内端部が前記凹壁部の下端部に抑え込まれて固定され、
前記窓部の孔縁と、前記各種のコネクタとの間の間隔は、前記制御基板のプリント配線に対して不正部品の接続を不能とする僅かな間隔に設定されることで、前記プリント配線を保護する構成にしてあるとともに、前記複数の封印締着部と前記複数の封印ボス部のうちから１つの封印締着部と封印ボス部とを封印締着部材で封印することで、前記ケース体と前記カバー対とを取り外し不能に封印し、その封印した状態で前記開封部を切断することにより前記ケース体と前記カバー体とを取り外し可能とし、再度次の封印締着部と封印ボス部とを封印締着部材で封印することで、前記ケース体と前記カバー対とを取り外し不能に封印したことを特徴とする。
請求項３の発明は、請求項１又は請求項２に記載の制御基板収納ボックスであって、
前記遮蔽部材は、その外縁部に前記ケース体の側壁上部に係合する係合縁を有していることを特徴とする。
【０００５】
【発明の効果】
請求項１の発明によれば、制御基板の実装面に配設された実装部品はカバー体により覆われ、このカバー体により覆われない凹壁部の外側の制御基板上に露出して配設された各種のコネクタと覆われた実装部品とが接続される。
また、凹壁部の下端部からケース体の側壁にわたって一体形成された遮蔽部材の窓部に対し、単数または複数のコネクタが挿通された状態において、窓部の孔縁と、各種のコネクタとの間の間隔が、制御基板のプリント配線に対して不正部品の接続を不能とする僅かな間隔に設定されることで、制御基板のプリント配線が保護される。このため、制御基板のプリントパターンに対し細工する不正を防止することができる。
更に、封印締着部と封印ボス部とを封印締着部材で封印してケース体とカバー対とを取り外し不能に封印することで、制御基板収納ボックスの不正開封を防止するようになっている。そして、その封印状態を複数回行うことができる。
また、請求項２の発明によれば、制御基板の実装面に配設された実装部品はカバー体により覆われ、このカバー体により覆われない凹壁部の外側の制御基板上に露出して配設された各種のコネクタと覆われた実装部品とが接続される。
また、凹壁部の下端部からケース体の側壁にわたり、且つカバー体とは別部材で形成された遮蔽部材の窓部に対し、単数または複数のコネクタが挿通された状態において、窓部の孔縁と、各種のコネクタとの間の間隔が、制御基板のプリント配線に対して不正部品の接続を不能とする僅かな間隔に設定されることで、制御基板のプリント配線が保護される。このため、制御基板のプリントパターンに対し細工する不正を防止することができる。
また、カバー体に対し遮蔽部材を別体とする構成とすることで、パチンコ機の機種により制御基板に配設される実装部品のカバー体は共通であるが、コネクタの大きさ、位置が異なる場合、遮蔽部材を取替えるだけで対処することができるのでコスト的に有利となる経済性を有する。
更に、封印締着部と封印ボス部とを封印締着部材で封印してケース体とカバー対とを取り外し不能に封印することで、制御基板収納ボックスの不正開封を防止するようになっている。そして、その封印状態を複数回行うことができる。
請求項３の発明によれば、遮蔽部材の係合縁がケース体の側壁に係合する構成とすることで、遮蔽部材と制御基板の間に針金等のこじ入れを阻止できてプリントパターンの破損を防止することができるとともに、この係合縁をケース体の側壁に係合することで、これを位置決め部として容易に組付けることができる。
【０００６】
【発明の実施の形態】
（第１の実施形態）
次に、本発明の実施形態を構成するものではないが本発明の前提となる実施形態を図面にしたがって説明すると、図１は制御基板収納ボックス１０の平面図、図２は図１のＡ−Ａ線断面図を示すもので、この制御基板収納ボックス１０は合成樹脂材からなるもので、制御基板１１を収納するケース体１２と、このケース体１２に取付けられて制御基板１１を覆うカバー体２５とより構成され、この制御基板収納ボックス１０は周知のようにパチンコ機の遊技盤の裏面に組付けられる図示しない裏カバー（詳しくは役物保護カバーあるいは裏機構板等に相当する）に取外し可能に取付けられる。
【０００７】
このケース体１２は略長方形状の底板１３とその四周には所定の高さで立上がる側壁１４ａ，１４ｂ，１４ｃ，１４ｄが形成されるとともに、その側壁１４ａ，１４ｂの角部は所定の角度で切欠き状に斜状壁１５が形成されている。また、底板１３の斜状壁１５側を挟む対角の図示隅部には基板取付用ボス１６ａ，１６ｂが立設され、また、斜状壁１５側には同斜状壁１５を底辺とする所定の三角頂点位置にはカバー取付用基準ボス１７が立設されている。また、側壁１４ａ，１４ｂ，１４ｃ，１４ｄおよび斜状壁１５の上縁には制御基板１１を同一面に嵌込む嵌込み凹部１８が連続して凹設されている。
【０００８】
このように形成されたケース体１２の嵌込み凹部１８に同一面に嵌込まれる制御基板１１は同嵌込み凹部１８に嵌込まれる略長方形状に形成されて、その嵌込み上面側が実装面２０とされ、この実装面２０のカバー体２５で覆われる部分には図示はしないがＲＯＭ、ＩＣ、ヒューズ等の部品が実装されている。また、この制御基板１１の所定の位置には放熱板２１ａ，２１ｂが配設されている。
【０００９】
また、この制御基板１１のケース体１２の斜状壁１５を挟む側壁１４ａ，１４ｂ側には２Ｐ電源コネクタＲＣＮおよびコネクタＣＮ１〜ＣＮ７が配設され、このコネクタＣＮ１〜ＣＮ７は例えば雄タイプのもので略長方形状の保護基板（コンタクトシェル）２２には所定のピッチで複数本のコンタクト端子２３がそれぞれ立設され、２Ｐ電源コネクタＲＣＮおよび各コネクタＣＮ１〜ＣＮ７のコンタクト端子２３は、制御基板１１に実装された部品に図示はしないが実装面２０に所定のプリントパターンで接続されたプリント配線が接続されている。このように実装部品を配設した制御基板１１はケース体１２の嵌込み凹部１８に嵌込まれ、また、基板取付用ボス１６ａ，１６ｂとカバー取付用基準ボス１７にはカバー体２５と共締め固定するようになっている。このように制御基板１１を嵌込んだケース体１２にはカバー体２５が実装部品を覆うように取付けられている。
【００１０】
このカバー体２５は変形四辺形状に形成されており、ケース体１２と合せ型されるもので、天板２６の四周には図示のようにケース体１２の側壁１４ａより所定の間隔ｈ１を有して平行状に所定の高さの凹壁部２７ａと，同じくケース体１２の側壁１４ｂより所定の間隔ｈ２を有して平行状に凹壁部２７ｂが、また、ケース体１２の側壁１４ｃ，１４ｄと突き合わせ整合する側壁２７ｃ，２７ｄが形成され、また、凹壁部２７ａ，２７ｂ間には、ケース体１２の斜状壁１５と突き合わせ整合する斜状壁２８が形成されるとともに、この斜状壁２８は接続壁２９ａ，２９ｂにより凹壁部２７ａ，２７ｂに一連に接続されている。
【００１１】
また、凹壁部２７ａと側壁２７ｃの対応する所定の位置には制御基板１１に配設した放熱板２１ａ，２１ｂの一部を露出して放熱する凹部３０が凹設されている。また、天板２６には図示はしないが制御基板収納ボックス１０内で発生する熱を逃がすための小径の放熱孔２６ａが多数貫設されている。
【００１２】
また、凹壁部２７ａ，２７ｂの側壁２７ｃ，２７ｄ側の下部には制御基板１１に重合して基板取付用ボス１６ａ，１６ｂに共締めする取付部３１ａ，３１ｂが形成され、この凹壁部２７ｂの下部側の取付部３１ｂと接続壁２９ｂ間にはコネクタＣＮ３〜ＣＮ７に向けて所定の張出し幅ｈ３で張出して各コネクタＣＮ３〜ＣＮ７に対し指で雌型コネクタ３５を抜き差しし易くするためのフランジ状の遮蔽部材３２が一体に形成されている。
【００１３】
また、このフランジ状の遮蔽部材３２は図２に示すように、その張出し先端下面には制御基板１１に当接する縁部３３が長手方向に沿って形成され、同遮蔽部材３２の先端面３４は制御基板１１に直列状に配設され、かつ凹壁部２７ｂに平行にして位置された保護基板２２に対し、僅かの間隔ｔを有して対設するように位置されて取付けられるように形成され、この遮蔽部材３２はコネクタＣＮ３〜ＣＮ７の各コンタクト端子２３に接続されたプリント配線のプリントパターンを遮蔽するとともに、先端面３４と保護基板２２との間隔ｔは、コンタクト端子２３に雌型コネクタ３５を着脱可能とする間隔ｔで、かつ外部から各プリントパターンに対し不正（他の不正部品を切断接続）不能な間隔ｔで取付けられるように設けられている。
【００１４】
また、凹壁部２７ａ側にも同様のフランジ状の遮蔽部材３６が設けられている。この遮蔽部材３６は接続壁２９ａより放熱凹部３０を跨ぎ、コネクタＣＮ１，ＣＮ２と対設する所定の範囲に設けられ、この遮蔽部材３６は所定の幅ｈ３に形成され、同遮蔽部材３６の先端下面には長手方向に沿って縁部３７が形成され、同縁部３７の先端面３８はコネクタＣＮ１，ＣＮ２の保護基板２２の対し、各コンタクト端子２３に接続されたプリント配線のプリントパターンを遮蔽するとともに、先端面３４と保護基板２２との間隔ｔは、上記遮蔽部材３２と同様にコンタクト端子２３に雌型コネクタ３５を着脱可能とする間隔ｔで、かつ外部から不正不能な間隔ｔで取付けられるように設けられている。
【００１５】
このように凹壁部２７ａ，２７ｂに遮蔽部材３２，３６を一体に形成したカバー体２５は、ケース体１２に形成した基板取付用ボス１６ａ，１６ｂおよびカバー取付用基準ボス１７に対し固定用ビスにより止着することにより、側壁１４ｃ，２７ｃと側壁１４ｄ，２７ｄおよび斜状壁１５，２８は突き合わせ状に整合されて制御基板１１の実装面２０に配設されたＲＯＭ、ＩＣ、ヒューズ等の実装部品はカバー体２５で覆われ、このカバー体２５により覆われない凹壁部２７ａ，２７ｂの外側の制御基板１１上に露出して配設されたコネクタＣＮ１，ＣＮ２およびコネクタＣＮ３〜ＣＮ７と覆われた実装部品とを接続した各プリント配線のプリントパターンは凹壁部２７ａ，２７ｂの下部側に形成した遮蔽部材３２，３６により遮蔽されている。
【００１６】
この遮蔽部材３２，３６のプリントパターンの遮蔽状態にあっては、その先端面３４，３８はコネクタＣＮ１，ＣＮ２およびコネクタＣＮ３〜ＣＮ７の保護基板２２に対し、外部から不正不能な間隔ｔで位置固定するように取付けられているので、同プリントパターンに対し細工する不正を防止することができる。
なお、遮蔽部材３２，３６の先端面３４，３８と各コネクタＣＮ１〜ＣＮ７の保護基板２２との間隔ｔを、プリント配線のプリントパターンを遮蔽するとともに、コンタクト端子２３に雌型コネクタ３５を着脱可能として不正不能な間隔ｔで取付けられるように構成したが、例えば先端面３４，３８を所定の角度で上方に開拡するテーパー面に形成して、テーパー面下部を保護基板２２に当接する構成としてもよい。
【００１７】
（第２の実施形態）
次に、本発明の実施形態を構成する第２の実施形態を図３ないし図１１にしたがって説明する。この第２実施形態の制御基板収納ボックス４０は上記制御基板収納ボックス１０とほぼ同様に制御基板４１を収納するケース体４２と、このケース体４２に取付けられて制御基板４１を覆うカバー体５５とより構成されている。
【００１８】
このケース体４２は略長方形状の底板４３とその四周には所定の高さで立上がる側壁４４ａ，４４ｂ，４４ｃ，４４ｄが形成されるとともに、その側壁４４ａ，４４ｂの角部は所定の角度で切欠き状に斜状壁４５が形成されている。また、底板４３の斜状壁４５を挟む対角の図示隅部には基板取付用ボス４６ａ，４６ｂが立設され、また、斜状壁４５側には同斜状壁４５を底辺とする所定の三角頂点位置にカバー取付用基準ボス４７が立設されている。また、側壁４４ａ，４４ｂ，４４ｃ，４４ｄおよび斜状壁４５の上縁には制御基板４１を同一面に嵌込む嵌込み凹部４８が連続して凹設されている。また、このケース体４２の側壁４４ｃには所定の間隔でカバー体５５を回動可能に掛合する掛合ピン４９ａと支持片４９ｂとからなる掛合部４９が形成されている。
【００１９】
また、ケース体４２の嵌込み凹部４８に同一面に嵌込まれる制御基板４１は上記基板１１と同様に嵌込み凹部４８に嵌込まれる略長方形状に形成されて、その嵌込み上面側が実装面５０とされ、この実装面５０のカバー体５５で覆われる部分には図示はしないがＲＯＭ、ＩＣ、ヒューズ等の部品が実装されている。また、この制御基板４１の所定の位置には放熱板５１ａ，５１ｂが配設されている。
【００２０】
また、この制御基板４１のケース体４２の斜状壁４５を挟む側壁４４ａ，４４ｂ側には２Ｐ電源コネクタＲＣＮおよびコネクタＣＮ１〜ＣＮ７が配設され、このコネクタＣＮ１〜ＣＮ７は例えば雄タイプのもので略長方形状の保護基板５２には所定のピッチで複数本のコンタクト端子５３がそれぞれ立設され、２Ｐ電源コネクタＲＣＮおよび各コネクタＣＮ１〜ＣＮ７のコンタクト端子５３は、制御基板４１に実装された部品に図示はしないが実装面５０に所定のプリントパターンで接続されたプリント配線が接続されている。このように実装部品を配設した制御基板４１は基板取付用ボス４６ａ，４６ｂおよびカバー取付用基準ボス４７にカバー体５５に固定用ビスにより共締め固定するようになっている。このように制御基板４１を取付けたケース体４２にはカバー体５５が実装部品を覆うように取付けられている。
【００２１】
このカバー体５５は上記カバー体２５とほぼ同様に変形四辺形状に形成されており、ケース体４２と合せ型されるもので、天板５６の四周には図示のようにケース体４２の側壁４４ａより所定の間隔ｈ１を有して平行状に所定の高さの凹壁部５７ａと，同じくケース体４２の側壁４４ｂより所定の間隔ｈ２を有して平行状に凹壁部５７ｂが、また、ケース体４２の側壁４４ｃ，４４ｄと突き合わせ整合する側壁５７ｃ，５７ｄが形成されている。また、凹壁部５７ａ，５７ｂ間には、ケース体４２の斜状壁４５と突き合わせ整合する斜状壁５８が形成されるとともに、この斜状壁５８は接続壁５９ａ，５９ｂにより凹壁部５７ａ，５７ｂに一連に接続されている。
【００２２】
また、凹壁部５７ａと側壁５７ｃの対応する所定の位置には制御基板４１に配設した放熱板５１ａ，５１ｂの一部を露出して放熱する凹部６０が凹設されている。また、天板５６には制御基板収納ボックス４０内で発生する熱を逃がすための小径の放熱孔５６ａが多数貫設されている。また、側壁５７ｃにはケース体４２の側壁４４ｃに形成した掛合部４９の掛合ピン４９ａに回動可能に掛合するフック部６１が形成されている。また、凹壁部５７ａ，５７ｂの側壁５７ｃ，５７ｄ側の上部には天板５６と同位にケース体４２の側壁４４ａ，４４ｂの上方へ臨む取付部６２が形成され、この両取付部６２の下面にはケース体４２の基板取付用ボス４６ａ，４６ｂと対応して有底筒状形状で下孔を有する取付支持体６２ａが垂設され、基板取付用ボス４６ａ，４６ｂにビス着するようになっている。また、斜状壁５８を底辺とする所定の三角頂点位置にはカバー取付用基準ボス４７と整合する有底で段差筒形状（図１５参照）の取付支持体６３が形成されている。
【００２３】
また、このケース体４２に制御基板４１を嵌込み、カバー体５５を型合せした状態で、例えば斜状壁４５，５８および側壁４４ｄ，５７ｄの側壁４４ａと取付部６２寄りには制御基板収納ボックス４０を封印する封印部群６５が配設され、この封印部群６５は、封印ビス６７によって封印可能な複数（図では４個の場合を例示する）の封印部６６を備えている。なお、この封印群６５は同一に構成されているので側壁４４ｄ，５７ｄ側の封印部群６５について図６ないし図１０を参照して説明し、他の封印部群の説明は省略する。なお、図６は封印部群６５の平面図、図７は封印部６６の封印状態を示す断面図、図８は封印ビス６７の仮止め状態の断面図、図９は封印部６６の分解断面図、図１０は封印ビス６７の説明図である。
【００２４】
先ず、封印ビス６７について図１０を参照して説明する。図１０において、封印ビス６７は、締めつけは可能であるが、弛めを不可能としたワンウエイタイプのネジであり、（ａ）は封印ビス６７の平面図、（ｂ）は正面図、（ｃ）は底面図、（ｄ）はネジ山６８ａの断面図である。封印ビス６７は、図（ａ）〜（ｃ）に示すように、ネジ山６８ａを外周に有する軸部６８と、十字ドライバー等の回動操作部材と係合する係合孔６９ａを上面に有する頭部６９とからなる。頭部６９の係合孔６９ａは、十字ドライバー等による回動工具の締めつけ方向（図（ａ）中、矢印Ａ方向参照）に関しては係合し、逆に弛め方向（図（ａ）中、矢印Ｂ方向参照）に関しては非係合となる形状に形成されている。また軸部６８のネジ山６８ａには、図（ｂ）及び（ｃ）に示されるように円周上に４ヶ所の溝部６８ｂがネジ山６８ａと交差状に形成されている。またネジ山６８ａのネジ山角は、図（ｄ）に示されるように上下非対称となっている。
【００２５】
上記の構成を有する封印ビス６７は、回動工具による締めつけを可能とする一方、回動工具の弛め方向（図９（ａ）中、矢印Ｂ方向参照）に対する頭部６９の係合力を小さくしかつ弛め方向のネジ山６８ａの回動抵抗を大きくすることにより、締めつけ状態からの取り外しが不能となっている。なお、このような封印ビス６７には、例えば日東精工株式会社製の商品名；ギザタイト、品番ＧＴＰ３ＸＬを使用することができ、あるいは実開昭５９−４７１１４号公報、特開平３−１０３６０７号公報に開示されたネジを代用することも可能である。
【００２６】
次に、封印部６６について説明する。図９に示すようにケース体４２の側壁４２ｄには、有底状の下孔７０ａを有する封印ボス部７０が開封部７０ｂを介して側方へ突出状に形成されている。またカバー体５５の側壁５７ｄ側には、ケース体４２の封印ボス部７０に対応して封印締着部７１が開封部７１ｂを介して側方へ突出状に形成されている。両開封部７０ｂ，７１ｂは、平面的に見てほぼ同じ幅の首状に細く形成されており、ニッパー、カッター等の切断工具により切断可能となっている。また封印ボス部７０と封印締着部７１との合わせ面には、相互に嵌まり合う円形の係合凸部７２ａと係合凹部７２ｂとからなる係合手段が設けられている。
【００２７】
また、封印締着部７１は、ほぼ円筒状に形成されており、図示下端部にビス孔７１ａを有しており、そのビス孔７１ａより図示上方部分にビス保持部７３を有している。ビス保持部７３の上半部には、周方向に２個のスリット７４が形成されている（図６参照）。また図において、封印ビス６７の頭部６９の外径をｄ１、軸部６８の外径をｄ２としたとき、ビス保持部７３の内径Ｄ１、ビス孔７１ａの口径Ｄ２、封印ボス部７０の下孔の内径Ｄ３は、Ｄ１＜ｄ１、Ｄ２＞ｄ２、Ｄ３＜ｄ２の寸法関係を満たすように形成されている。また封印締着部７１は、封印ビス６７を収容可能な高さを有している。
【００２８】
また、封印締着部７１において、ビス保持部７３に封印ビス６７が挿入されることにより、封印ビス６７の頭部６９によりビス保持部７３がスリット７４間を開くように拡開され、その拡開に抵抗する弾性によって頭部６９が保持されることによって仮止めされる（図８参照）。そして、ケース体４２に対するカバー体５５の組付けにともないケース体４２の封印ボス部７０とカバー体５５の封印締着部７１とが係合凸部７２ａと係合凹部７２ｂの嵌め合いを介して同一軸線上に位置する（図８参照）。そして封印に際しては、封印ビス６７が回動工具によって当該封印ボス部７０の下孔７０ａに締め付けられることによって封印がなされる（図７参照）。
【００２９】
次に、図１１に示すように各封印締着部７１の図示右側面にはそれぞれ凸部７１ｃが側方へ張出し状に形成されている。一方、各封印ボス部７０の図示右側の側面にもほぼ同じ形状の凸部７０ｃが側方へ張出し状に形成されているが、各凸部７０ｃ，７０ｃ間は相互に補助開封部７５により一体に連結されている。このため、図３および図６に示すように、当該封印部群６５を平面的に見ると、ケース体４２側の開封部７０ｂはカバー体５５側の開封部７１ｂにちょうど重ね合わさっているため目視できないが、上記補助開封部７５〜７５はケース体４２側にのみ形成されてカバー体５５側の凸部７１ｃからはみ出しているので平面的に見ても直接目視することができるようになっている。
【００３０】
次に、図６に示すように、封印部群６５の４個の封印部６６は、図示上から下へ１回目用、２回目用、３回目用、４回目用の封印部６６となっており、カバー体５５の開封部７１ｂの上面およびケース体４２の開封部７０ｂの下面には、封印順位を示す「１，２，３，４」の封印番号７７が付されている。制御基板収納ボックス４０の組み立て完了時には、各封印部群６５の「１」の封印番号７７の封印部６６が封印ビス６７によって封印されており、各封印部群６５の「２，３，４」の封印番号７７の封印部６６は予備であって封印されていない。なお、封印番号７７は、印刷、刻み込み、樹脂成形金型によって付けることができる。また、封印番号は、算用数字の他、ローマ数字、アルファベット、記号等でも代用することが可能である。
【００３１】
また、図６に示すように、カバー体５５の各開封部７１ｂおよび各凸部７１ｃの上面にはローレットにより細かい網目模様７８が形成されている。網目模様７８は、ローレットによる他、樹脂成形金型によって成形することもできる。なお網目模様７８の形状は、図示した格子目の他、すじ目、斜目にしてもよい。さらに、図示は省略したが網目模様７８は、ケース体４２の開封部７０ｂ、凸部７０ｃおよび補助開封部７５の下面にも上記と同様に設けられている。
【００３２】
このように封印部群６５を附設することで本実施形態の制御基板収納ボックス４０によれば、ケース体４２とカバー体５５とを取り外し不能に封印する封印ビス６７によって各封印部群６５の「１」の封印番号７７の封印部６６が封印されているため、当該制御基板収納ボックス４０の不正開封を防止するようになっている。
【００３３】
また、カバー体５５の凹壁部５７ａの下部側の接続壁５９ａより凹壁部５７ａの端部間には遮蔽部材８０が、また、凹壁部５７ｂの下部側の接続壁５９ｂより凹壁部５７ｂの端部間には遮蔽部材８３が形成されている。
【００３４】
この遮蔽部材８０は凹壁部５７ａの下部より図示のようにケース体４２の側壁４４ａの上方位置に張出す幅ｈ４に形成され、この張出し端部の長手方向にはケース体４２の側壁４４ａの上縁に係合する係合縁８１が形成されている。また、この遮蔽部材８０には制御基板４１に配設された２Ｐ電源コネクタＲＣＮおよびコネクタＣＮ１，ＣＮ２を嵌込み挿通可能とする窓部８２ａ，８２ｂが開設され、この窓部８２ｂの長さはパチンコ機の機種により、コネクタＣＮのコンタクト端子５３の数の異なる保護基板５２の形状等に対処する長さに形成されている。また、この窓部８２ａ，８２ｂの凹壁部５７ａ側の各縁面８２ｃは上記第１実施形態の遮蔽部材３２，３６の先端面３４，３８と同様に２Ｐ電源コネクタＲＣＮおよびコネクタＣＮ１，ＣＮ２の保護基板５２と間隔ｔを有し、かつ同遮蔽部材８０により２Ｐ電源コネクタＲＣＮおよびコネクタＣＮ１，ＣＮ２のコンタクト端子５３に接続されたプリント配線のプリントパターンを遮蔽可能に設けられ、間隔ｔはコンタクト端子５３に雌型コネクタ３５を着脱可能とする間隔ｔで、かつ外部から不正不能な間隔ｔに設けられている。
【００３５】
また、凹壁部５７ｂの下部側に形成される遮蔽部材８３は上記遮蔽部材８０と同様にケース体４２の側壁４４ｂより所定の長さ張出す幅ｈ５に形成され、この張出し端部の下面側の長手方向にはケース体４２の側壁４４ｂの上縁に係合する係合縁８４が形成されている。また、この遮蔽部材８３には制御基板４１に配設されたコネクタＣＮ３，ＣＮ４を嵌込み挿通可能とする幅および長さを有する細長状の窓部８５，８６とコネクタＣＮ５，ＣＮ６，ＣＮ７を一連に嵌込み挿通可能とする窓部８７が開設されている。なお、この窓部８７の長さは上記窓部８２と同様にパチンコ機種によりコネクタＣＮのコンタクト端子５３の数の異なる保護基板５２の形状等に対処する長さに形成されている。また、この各窓部８５，８６，８７の凹壁部５７ａ側の縁面８５ａ，８６ａ，８７ａは上記した遮蔽部材８０の窓部８２ａ，８２ｂの縁面８２ｃと同様にコネクタＣＮ３〜ＣＮ７の各保護基板５２と、外部から不正不能な間隔ｔを有し、かつ同遮蔽部材８３により各コネクタＣＮ３〜ＣＮ７のコンタクト端子５３に接続されたプリント配線のプリントパターンを遮蔽可能に設けられている。
【００３６】
このように凹壁部５７ａ，５７ｂに遮蔽部材８０，８３を形成したカバー体５５を、その側壁５７側に形成したフック部６１をケース体４２の側壁４４ｃに形成した掛合部４９の掛合ピン４９ａに掛合してケース体４２に嵌込んだ制御基板４１の上方へ回動載置してカバー取付用基準ボス４７および基板取付用ボス４６に対し固定用ビスにより止着することで、上記した各封印部群６５の封印部６６を構成する封印ボス部７０と封印締着部７１は整合されて相互の係合凸部７２ａと係合凹部７２ｂを介して嵌合結合される。
【００３７】
この状態で、各封印部群６５の「１」の封印番号７７の封印部６６が封印ビス６７によって封印されることで制御基板４１の実装面５０に配設されたＲＯＭ、ＩＣ、ヒューズ等の部品は遮蔽され、このカバー体５５の凹壁部５７ａ，５７ｂより外側に配設された２Ｐ電源コネクタＲＣＮおよびコネクタＣＮ１，ＣＮ２およびコネクタＣＮ３〜ＣＮ７は同凹壁部５７ａ，５７ｂの下部に沿って形成された遮蔽部材８０，８３に開設した窓部８ａ，８２ｂおよび窓部８５，８６，８７に挿通されるとともに、各窓部８２ａ，８２ｂ，８５，８６，８７の各縁面８２ｃ，８５ａ，８６ａ，８７ａは２Ｐ電源コネクタＲＣＮおよびコネクタＣＮ１〜ＣＮ７の各保護基板５２と間隔ｔを有し、かつ同遮蔽部材８０，８３により２Ｐ電源コネクタＲＣＮおよび各コネクタＣＮ１〜ＣＮ７のコンタクト端子５３に接続されたプリント配線のプリントパターンを遮蔽しており、さらに、同遮蔽部材８０，８３の端部長手方向に形成した係合縁８１，８４はケース体４２の側壁４４ａ，４４ｂに係合されている。
【００３８】
この遮蔽部材８０，８３に開設した窓部８２ａ，８２ｂおよび窓部８５，８６，８７に２Ｐ電源コネクタＲＣＮとコネクタＣＮ１，ＣＮ２およびコネクタＣＮ３〜ＣＮ７を挿通し、プリント配線のプリントパターンを遮蔽した状態で、その各縁面８２ｃ，８５ａ，８６ａ，８７ａはコネクタＣＮ１〜ＣＮ７の各保護基板５２に対し、外部から不正不能な間隔ｔで位置固定するように取付けられているので、同プリント配線に対し細工する不正を防止することができ、さらには、遮蔽部材８０，８３の係合縁８１，８４がケース体４２の側壁４４ａ，４４ｂに係合されていることから、遮蔽部材８０，８３と制御基板４１の間に針金等のこじ入れを阻止できてプリントパターンの破損を防止することができる。
【００３９】
（第３の実施形態）
次に、本発明の実施形態を構成する第３の実施形態を図１２ないし図１６にしたがって説明する。この第３実施形態の制御基板収納ボックス９０は上記した第２実施形態の制御基板収納ボックス４０とほぼ同様に形成され、異なる点は上記カバー体５５に一体に形成した遮蔽部材８０，８３を別体に構成したことである。
【００４０】
この制御基板収納ボックス９０は制御基板９１を収納するケース体９２と、このケース体９２に取付けられて制御基板９１を覆うカバー体１００と上記した遮蔽部材８０，８３と同様に機能するサブカバー１１５（遮蔽部材ともいう）とより構成されている。
【００４１】
このケース体９２は略長方形状の底板９３とその四周には所定の高さで立上がる側壁９４ａ，９４ｂ，９４ｃ，９４ｄが形成されるとともに、その側壁９４ａ，９４ｂの角部は所定の角度で切欠き状に斜状壁９５が形成されている。また、底板９３の斜状壁９５を挟む対角の図示隅部には基板取付用ボス９６ａ，９６ｂが立設され、また、斜状壁９５を底辺とする所定の三角頂点位置にはカバー体１００とサブカバー１１５の取付用基準ボス９７が立設されている。また、側壁９４ａ，９４ｂ，９４ｃ，９４ｄおよび斜状壁９５の上縁には制御基板９１を同一面に嵌込む嵌込み凹部９８が連続して凹設されている。
【００４２】
また、ケース体９２の嵌込み凹部９８に同一面に嵌込まれる制御基板９１は上記とほぼ同様に嵌込み凹部９８に嵌込まれる略長方形状に形成されて、その嵌込み上面側が実装面９９とされ、この実装面９９のカバー体１００で覆われる部分には図示はしないがＲＯＭ、ＩＣ、ヒューズ等の部品が実装されている。また、この制御基板９１の所定の位置には放熱板５１ａ，５１ｂが配設されている。
【００４３】
また、この制御基板９１のケース体９２の斜状壁９５を挟む側壁９４ａ，９４ｂ側には上記と同様に２Ｐ電源コネクタＲＣＮおよびコネクタＣＮ１〜ＣＮ７が配設され、このコネクタＣＮ１〜ＣＮ７は例えば雄タイプのもので保護基板５２には所定のピッチで複数本のコンタクト端子５３がそれぞれ立設され、２Ｐ電源コネクタＲＣＮおよび各コネクタＣＮ１〜ＣＮ７のコンタクト端子５３は、制御基板９１に実装された部品に図示はしないが実装面９９に所定のプリントパターンで接続されたプリント配線が接続されている。このように実装部品を配設した制御基板９１はケース体９２の嵌込み凹部９８に嵌込まれるとともに、基板取付用ボス９６ａ，９６ｂおよび取付用基準ボス９７とサブカバー１１５を介してカバー体１００と固定用ビスにより共締め固定するようになっている。このように設けられたケース体９２にはカバー体１００が取付けられている。
【００４４】
このカバー体１００は上記カバー体５５と同様に変形四辺形状に形成されており、ケース体９２と合せ型されるもので、同天板１０１の四周には図示のようにケース体９２の側壁９４ａより所定の間隔ｈ１を有して平行状に所定の高さの凹壁部１０２と，同じくケース体９２の側壁９４ｂより所定の間隔ｈ２を有して平行状に凹壁部１０３が、また、ケース体９２の側壁９４ｃ，９４ｄと突き合わせ整合する側壁１０４，１０５が形成されている。また、凹壁部１０２，１０３間には、ケース体９２の斜状壁９５と突き合わせ整合する斜状壁１０６が形成されるとともに、この斜状壁１０６は接続壁１０７ａ，１０７ｂにより凹壁部１０２，１０３に一連に接続されている。
【００４５】
また、凹壁部１０２と側壁１０４の対応する所定の位置には制御基板９１に配設した放熱板５１ａ，５１ｂの一部を露出して放熱する凹部１０８が凹設されている。また、凹壁部１０２の側壁１０５側の上部には天板１０１と同位にケース体９２の側壁９４ａの上方に臨む取付部１０９が張出し形成され、この取付部１０９の下面にはケース体９２の基板取付用ボス９６ａと対応して有底筒状形状で下孔を有する取付支持体１１０が垂設され、基板取付用ボス９６ａに後述するサブカバー１１５と共締めするようになっている。また、天板１０１には制御基板収納ボックス９０内で発生する熱を逃がすための小径の放熱孔１０１ａが多数貫設されている。
【００４６】
また、このカバー体１００の斜状壁１０６側の天板１０１には取付用基準ボス９７と対応して有底段差筒形状で下孔を有する取付支持体１１１が垂設されている（図１５参照）。このように形成されたカバー体１００の凹壁部１０２，１０３、接続壁１０７ａ，１０７ｂおよび斜状壁１０６と取付支持体１１０，１１１の高さ寸法は後述するサブカバー１１５を抑え込むため、側壁１０４，１０５の高さ寸法よりサブカバー１１５の厚さ寸法分短く形成されている。
【００４７】
また、このケース体９２に制御基板９１を嵌込み、サブカバー１１５を介してカバー体１００を型合せした状態で、例えば斜状壁９５，１０６および側壁９４ｄ，１０５の凹壁部１０２寄りには制御基板収納ボックス９０を封印する封印部群６５が配設されている。なお、この封印部群６５は第２実施形態と同じ構成であるのでその説明は省略する。
【００４８】
次に、サブカバー１１５について説明すると、図１２に示すようにこのサブカバー１１５は制御基板９１のケース体９２の側壁９４ａ、斜状壁９５、側壁９４ｂに沿って取付けられるとともに、カバー体１００の凹壁部１０２，１０３、接続壁１０７ａ，１０７ｂおよび斜状壁１０６と取付支持体１１０，１１１により抑え込み状に取付けられるもので、このサブカバー１１５は図１６に示すように短尺カバー部１１６と長尺カバー部１１７と斜状部１１８とより略直角形状に構成されている。
【００４９】
このサブカバー１１５の幅Ｈは、ケース体９２とカバー体１００とを型合わせして組付けた状態での例えばケース体９２の側壁９４ａの外側面とカバー体１００の凹壁部１０２の内側面との間隔寸法に形成され、このサブカバー１１５の下面側の四周には所定の高さで縁部１１９が形成されている。また、短尺カバー部１１６内側となる縁にはカバー体１００の凹部１０８と対して放熱板５１ａの逃し部１２０が形成されている。また、斜状部１１８の内側縁のほぼ中央部には取付用基準ボス９７上部に位置し、かつカバー体１００の取付支持体１１１に押圧されて制御基板９１と共締めされる取付凸部１２１が形成され、この取付凸部１２１には取付用基準ボス９７の下孔と整合するビス孔１２２が貫設されている。また、短尺カバー部１１６の端部側にはケース体９２の基板取付用ボス９６ａの上部に位置し、カバー体１００の取付支持体１１１に押圧されて制御基板９１と共締めするためのビス孔１２３が貫設されている。また、長尺カバー部１１７の端部側はケース体９２の基板取付用ボス９６ｂの上部に位置し、同基板取付用ボス９６ｂの下孔と整合して制御基板９１と共締めするためのビス孔１２４が貫設されている。
【００５０】
また、短尺カバー部１１６と長尺カバー部１１７の外側の縁部１１９の所定の範囲にはケース体９２の側壁９４ａ，９４ｂの上縁に係合する係合縁１２５，１２６が垂設されている。また、短尺カバー部１１６には制御基板９１に配設された２Ｐ電源コネクタＲＣＮを嵌込み挿通可能に略方形状の窓部１２７と、コネクタＣＮ１，ＣＮ２を嵌込み挿通可能とする略長方形状の窓部１２８，１２９が貫設されている。また、長尺カバー部１１７には同じく制御基板９１に配設されたコネクタＣＮ３〜ＣＮ７を嵌込み挿通可能に窓部１３０，１３１，１３２，１３３，１３４が貫設されている。
【００５１】
このように形成されたサブカバー１１５の窓部１２７〜１３４を２Ｐ電源コネクタＲＣＮおよび各コネクタＣＮ１〜ＣＮ７に挿通してケース体９２の側壁９４ａ，９４ｂの上縁に係合縁１２５，１２６を係合した状態で、各窓部１２７，１２８，１２９，１３０，１３１，１３２，１３３，１３４のカバー体１００の凹壁部１０２，１０３側の縁面１２７ａ，１２８ａ，１２９ａ，１３０ａ，１３１ａ，１３２ａ，１３３ａ，１３４ａは上記と同様に２Ｐ電源コネクタＲＣＮおよび各コネクタＣＮ１〜ＣＮ７の保護基板５３と間隔ｔを有し、かつ同サブカバー１１５により２Ｐ電源コネクタＲＣＮおよび各コネクタＣＮ１〜ＣＮ７のコンタクト端子５３に接続されたプリント配線のプリントパターンを遮蔽可能に設けられ、この間隔ｔは上記と同様に、コンタクト端子５３に雌コネクタ３５を着脱可能とする間隔ｔで、かつ外部から不正不能な間隔ｔに設けられている。
【００５２】
このように形成されたケース体９２に形成された嵌込み凹部９８にはＲＯＭ，ＩＣ，ヒューズ等を実装した制御基板９１が嵌込まれる。そして、サブカバー１１５は上記したように窓部１２７〜１３４を２Ｐ電源コネクタＲＣＮおよび各コネクタＣＮ１〜ＣＮ７に挿通してケース体９２の側壁９４ａ，９４ｂの上縁に係合縁１２５，１２６を係合した状態で、そのビス孔１２３，１２４はケース体９２の基板取付用ボス９６ａ，９６ｂと整合する位置に、また、取付凸部１２１は取付用基準ボス９７と整合して位置し、ビス孔１２４側を基板取付用ボス９６にビス着する。このサブカバー１１５の取付状態でカバー体１００をケース体９２に型合わせすることで、カバー体１００に形成された取付部１０９の取付支持体１１０はサブカバー１１５のビス孔１２３に当接整合され、また、斜状壁１０６側の取付支持体１１１は取付凸部１２１に当接整合される。
【００５３】
そして、カバー体１００の凹壁部１０２は短尺カバー部１１６の内側縁上に、また、凹壁部１０３は長尺カバー部１１７の内側縁上に沿って位置されるとともに、接続壁１０７ａ，１０７ｂはサブカバー１１５を横切り、斜状壁１０６はサブカバー１１５の斜状部１１８の外側縁に沿って位置され、この状態で取付支持体１１０，１１１に取付ビスが挿入されて基板取付用ボス９６ａおよび取付用基準ボス９７に止着することで、サブカバー１１５は凹壁部１０２，１０３、接続壁１０７ａ，１０７ｂおよび斜状壁１０６により抑え込み状に取付けられている。なお、この取付状態で、第２実施形態と同様に各封印群６５の封印部６６を構成する封印ボス部７０と封印締着部７１は整合されて相互の係合凸部７２ａと係合凹部７２ｂを介して嵌合結合され、各封印群６５の「１」の封印番号７７の封印部６６が封印ビス６７よって封印される。
【００５４】
このようにしてサブカバー１１５はカバー体１００の凹壁部１０２，１０３、接続壁１０７ａ，１０７ｂおよび斜状壁１０６により抑え込み状に取付けられた状態で、同サブカバー１１５に開設した窓部１２７〜１３４に２Ｐ電源コネクタＲＣＮおよび各コネクタＣＮ１〜ＣＮ７を嵌合挿通した状態で各プリント配線のプリントパターンは遮蔽されるとともに、各縁面１２７ａ，１２８ａ，１２９ａ，１３０ａ，１３１ａ，１３２ａ，１３３ａ，１３４ａは２Ｐ電源コネクタＲＣＮおよび各コネクタＣＮ１〜ＣＮ７の各保護基板５２に対し、外部から不正不能な間隔ｔで取付けられているので、同プリント配線に対し細工する不正を防止することができ、さらには、サブカバー１１５の係合縁１２５，１２６がケース体９２の側壁９４ａ，９４ｂに係合されているので、サブカバー１１５と制御基板９１の間に針金等のこじ入れを阻止できてプリントパターンの破損を防止することができる。
【００５５】
また、この制御基板収納ボックス９０はカバー体１００に対しサブカバー１１５を別体とする構成としたので、パチンコ機の機種により制御基板９１に配設される実装部品のカバー体１００は共通であるが、コネクタの大きさ、位置が異なる場合、サブカバー１１５を取替えるだけで対処することができるのでコスト的に有利となる経済性を有する。
また、サブカバー１１５とカバー体１００、ケース体９２は共締めされているので、サブカバー１１５のみを取り外すことができない。したがって、サブカバー１１５のみを取り外してプリントパターンに不正を行うことはできない。
【００５６】
また、ケース体９２に形成された基板取付用ボス９６ａ，９６ｂと取付用基準ボス９７に対し、サブカバー１１５にはビス孔１２３，１２４と取付凸部１２１を有するとともに、ケース体９２の側壁９４ａ，９４ｂに係合する係合縁１２５，１２６を有することから、これらを位置決め部として容易に組付けることができる。
なお、この第２実施形態の窓部８２ａ，８２ｂおよび窓部８５〜８７の縁面８２ｃ，８５ａ〜８７ａ、さらに、第３実施形態の窓部１２７〜１３４の各縁面１２７ａ〜１３４ａは第１実施形態の先端面３４のように所定の角度で上方に開拡するテーパー面に形成して、テーパー面下部を保護基板５２に当接する構成としてもよい。
