Description

【０００１】
【発明の属する技術分野】
この発明は、遊技機の制御回路基板を収容する基板ボックスに関する。
【０００２】
【従来の技術】
従来の遊技機、例えばパチンコ遊技機において、遊技機の裏面側には、遊技機の遊技制御を行う役物制御装置や球排出装置を制御する球排出制御装置等の制御回路をボックス内に収容した基板ボックスが設けられている。
【０００３】
基板ボックスは、ＩＣ（集積回路）や抵抗等の各種電子部品が多数実装された制御回路基板を樹脂性や金属性のボックスに収容して、ショート等を防いだり、ほこり等のゴミが侵入しないように保護しており、遊技機の本体枠（前面枠）や基枠体としての裏メカベース盤あるいは遊技盤等の裏面側に取付け可能となっている。
【０００４】
例えば、役物制御装置においては、制御回路内にＣＰＵ、ＲＯＭ（メモリ）、ＲＡＭ（メモリ）等が設けられており、ＲＯＭに記憶されたプログラムにしたがい遊技制御が行われ、大当たり等もここで制御されている。
【０００５】
基板ボックスは、一般的に上蓋部材とベース部材とを重ね合わせたボックス体になっており、その他の各種装置と電気的に接続するためのコネクタ部がボックスから露出して設けられており、各種配線をコネクタ部に差し込むことにより、それぞれに関わる制御が可能となっている。
【０００６】
基板ボックスに対する不正行為は、上蓋部材をはずして、開放された制御回路基板に備えられたＲＯＭ等の電子部品を交換、あるいはデータの書き換え（例えば、大当たり確率を通常のものより高く設定する等）を行うことにより、通常の遊技制御と比較して、例えば大当たりを頻繁に出現させる等の不正な遊技制御を行うようにしていた。
【０００７】
このため、基板ボックスにおいては、一旦開放されると、開放されたことが分かるように、上蓋部材とベース部材との合わせ目に封印シールを貼ったり、あるいは基板ボックスの表面をクリアな樹脂により形成して、収容されている制御回路基板の状態を外部から見えるようにしていた。
【０００８】
【発明が解決しようとする課題】
しかしながら、従来の基板ボックスは、上蓋部材とベース部材を構造的にビス止めのみで組付けていたため、上蓋部材をはずしてボックス体を開放することは容易であり、また上蓋部材とベース部材との合わせ目に封印シールを貼っていたとしても、これは安易な不正行為者には効果があるが、非常に専門的な不正行為者、例えば偽の封印シールや特殊な剥離材等をもっている者に対しては効果がなくなっているのが実状であった。
【０００９】
不正行為者は、一般的に基板ボックスの封印を解いても、封印を解いたことをごまかそうと、遊技機に設置した状態では見えないように細工を施す。例えば、遊技機裏側から見えない部分から基板ボックスを無理やり開封したり、開封した場所を隠したりする。また、上記の偽封印シールを持っている者では、封印シールを剥がした痕跡が残っている上から偽シールを貼ったりする。
【００１０】
これらの不正行為を防止するためには、基板ボックスを開放不可能あるいは開放が非常に困難な構造にすることが考えられるが、遊技店においては、一旦設置した遊技機に対して抜打ち的に公的機関（警察等）により不正基板かどうかの検査が行われる。検査内容としては、ＲＯＭに記憶されているプログラムデータをデータローダにより読み込んで正規なＲＯＭと比較するといった検査が行われ、この場合に前述のごとく基板ボックスの開放が不可能であると、検査ができなくなってしまう。そのため、基板ボックスを破壊して開放することも考えられるが、基板ボックスを破壊してしまうと、検査後に再使用することができなくなってしまう。
【００１１】
そこで、本発明の目的は、制御回路基板を収容した基板ボックスの不正な開放を防止可能とした上で、検査や修理の際の開放を可能とすると共に、基板ボックスの不正な開放を容易に判別することができ、不正行為の隠蔽工作を防止可能とする遊技機の基板ボックスを提供することにある。
【００１２】
【課題を解決するための手段】
第１の発明は、遊技機に設けられる電気的作動装置の制御を行うためにＲＯＭ等の電子部品を実装した制御回路基板を収容する遊技機の基板ボックスにおいて、前記基板ボックスを構成する上蓋部材とベース部材とには、当該基板ボックスを閉じた状態において対向状態となる対向部を形成し、前記対向部の所定部位には、前記上蓋部材とベース部材とから各々突出させた連結部を介して重合する重合結合部を複数形成して、このうちのいずれか一つの重合結合部に対し締め方向しか回せない締結部材により固着せしめて前記ベース部材に対して前記上蓋部材を開放不能に閉止する不正開放防止結合手段を設けており、前記重合結合部は、前記上蓋部材の周壁から突出させた上方連結部の先端に形成された上方結合部と、前記ベース部材の周壁から突出させた下方連結部の先端に形成された下方結合部と、からなり、前記上方結合部には、該上方結合部の中央に前記締結部材の締結部が挿入される所定径の通し穴と、前記通し穴の上部に締結部材の頭部を囲う埋め込み穴と、が形成され、前記下方結合部には、前記通し穴につながり前記締結部材の締結部が挿入される所定深さの穴が形成されて、前記基板ボックスを開ける場合は、前記締結部材により固着されている重合結合部の上方連結部と下方連結部とを切断して、該重合結合部を取り除き、前記基板ボックスを閉止する際には、切除されていない重合結合部に対し締結部材により固着するようにし、前記基板ボックスを閉じた状態にて、前記上方連結部が前記下方連結部に形成された溝に嵌合され、前記下方連結部の断面外形幅を、前記上方連結部の断面外形幅よりも大きく設定した。
【００１４】
第２の発明は、遊技機に設けられる電気的作動装置の制御を行うためにＲＯＭ等の電子部品を実装した制御回路基板を収容する遊技機の基板ボックスにおいて、前記基板ボックスを構成する上蓋部材とベース部材とには、当該基板ボックスを閉じた状態において対向状態となる対向部を形成し、前記対向部の所定部位には、前記上蓋部材とベース部材とから各々突出させた連結部を介して重合する重合結合部を複数形成して、このうちのいずれか一つの重合結合部に対し締め方向しか回せない締結部材により固着せしめて前記ベース部材に対して前記上蓋部材を開放不能に閉止する不正開放防止結合手段を設けており、前記重合結合部は、前記上蓋部材の周壁から突出させた上方連結部の先端に形成された上方結合部と、前記ベース部材の周壁から突出させた下方連結部の先端に形成された下方結合部と、からなり、前記上方結合部には、該上方結合部の中央に前記締結部材の締結部が挿入される所定径の通し穴と、前記通し穴の上部に締結部材の頭部を囲う埋め込み穴と、前記上方結合部の下面で前記通し穴の回りに段状の係合突部と、が形成され、前記下方結合部には、該下方結合部の上部に前記係合突部が嵌まる係合受部と、前記係合受部の中央に前記通し穴につながり前記締結部材の締結部が挿入される所定深さの穴と、が形成されて、前記基板ボックスを開ける場合は、前記締結部材により固着されている重合結合部の上方連結部と下方連結部とを切断して、該重合結合部を取り除き、前記基板ボックスを閉止する際には、切除されていない重合結合部に対し締結部材により固着するようにし、前記基板ボックスを遊技機の所定位置に取付けた状態において、ほぼ正面側から視認可能に前記上方連結部と前記下方連結部とを互い違いに形成した。
【００１７】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
【００１８】
図１は遊技機の一例としてパチンコ遊技機を示しており、１はフレーム内に遊技盤を取付ける前面枠（本体枠とも呼ぶ）、２は前面枠１を支持する外枠である。前面枠１は、外枠２にヒンジ３ａ，３ｂにより開閉可能に組付けられ、その自由端側に施錠フック４ａ，４ｂが設けられる。外枠２は、遊技店の島設備に固定される。
【００１９】
遊技盤は、図示しないが、遊技領域に画像表示装置、変動入賞装置、入賞球センサ、ＬＥＤ、ランプ等の各種電気機器が配設される。
【００２０】
前面枠１には、遊技盤の前面を覆うカバーガラス５が開閉可能に取付けられ、下部には球の供給皿６、受皿７、打球発射装置のハンドル８等が設けられる。
【００２１】
図２はこの遊技機の背面図であり、１０は前面枠１の裏面に取付けられる基枠体（裏メカベース盤）、１１は球貯留タンク、１２は画像表示装置の表示制御装置、１３は球排出装置等を制御する球排出制御装置、１４は変動入賞装置、入賞球センサ、ＬＥＤ、ランプ等の各種電気機器の制御を行うと共に、表示制御装置１２、球排出制御装置１３等に制御信号を送る役物制御装置、１５は役物制御装置１４の基板ボックス、１６は打球発射制御装置である。
【００２２】
基板ボックス１５は、裏メカベース盤１０の表面（遊技機の裏面）に取付けられ、その役物制御装置１４と各種電気機器、各制御装置等とは配線コード群１７〜２０を介して電気的に接続される。
【００２３】
図３は基板ボックス１５の斜視図で、図４は分解斜視図であり、２５はベース部材、２６は上蓋部材、２７は下部保護板、２８は上部保護板、３０は役物制御装置１４の制御回路基板、３１は制御回路基板３０に実装された電子部品のうちのＲＯＭ、３２は制御回路基板３０の一側部に形成された配線コード群の接続領域３３に設けられたコネクタ部である。
【００２４】
遊技プログラムが記憶されたＲＯＭ３１は、制御回路基板３０のほぼ中央に配設される。
【００２５】
ベース部材２５は、透明の樹脂からなり、制御回路基板３０よりもいくらか大きい底部３４には格子状にリブが設けられ、底部３４の四方には高さの低い周壁３５ａ〜３５ｄが形成される。
【００２６】
ベース部材２５の底部３４の２つの隅および周壁３５ａ，３５ｃに沿う所定の位置には、下部保護板２７、制御回路基板３０、上部保護板２８をネジ止めする止着用ボス３６が形成される。制御回路基板３０の配線コード群の接続領域３３側の周壁３５ｄには、その接続領域３３の基板端部の受け（図示しない）が設けられ、底部３４の中央付近には、制御回路基板３０のＲＯＭ３１に対応する位置に、ＲＯＭ３１の着脱時に制御回路基板３０が曲がったりしないように、支えボス３７が設けられる。
【００２７】
上蓋部材２６は、透明の樹脂からなり、制御回路基板３０の配線コード群の接続領域３３を除いて、制御回路基板３０および上部保護板２８を覆うと共に、ベース部材２５の三つの周壁３５ａ〜３５ｃに上蓋部材２６の周壁３８ａ〜３８ｃの先端が合う大きさに形成される。
【００２８】
上蓋部材２６とベース部材２５との間には、周壁３８ａと周壁３５ａとの間に係脱可能な蝶着部４０が設けられ、その反対側の周壁３８ｃと周壁３５ｃとの間に突起４１と門型の係止片４２とからなる係止部４３が設けられる。上蓋部材２６をほぼ全開位置まで開くと蝶着部４０によって上蓋部材２６をベース部材２５から取り外すことが可能であり、上蓋部材２６を閉じると係止部４３によって上蓋部材２６がベース部材２５に係止されると共に、位置決めされる。
【００２９】
上蓋部材２６の天板部４４には、制御回路基板３０の電源部に対応して放熱孔４５が形成される。周壁３８ｂには、制御回路基板３０に配設される遊技機の確率設定器に確率設定キーを差し込んで確率をセットするための穴４６が設けられる。
【００３０】
下部保護板２７は、ベース部材２５側からの静電気等の耐ノイズ用に金属製から形成され、透明のベース部材２５を通して外部から制御回路基板３０を視認可能に多数の六角形の孔が設けられている。制御回路基板３０を視認可能であれば、六角形に限らず、丸型やその他の多角形の孔でも良い。
【００３１】
上部保護板２８は、静電気等の耐ノイズ用に金属製から形成され、透明の上蓋部材２６を通して外部から制御回路基板３０を視認可能に中央部が大きくくりぬかれている。
【００３２】
この基板ボックス１５の上蓋部材２６をベース部材２５に対して閉じたときに対向する周壁のうち、制御回路基板３０の配線コード群の接続領域３３側の周壁３８ｄ，３５ｄおよび蝶着部４０側の周壁３８ａ，３５ａを除く周壁３８ｂ，３５ｂ，３８ｃ，３５ｃの所定の位置に、即ち上蓋部材２６側から見て複数ある辺部のうち、配線コード群の接続領域３３側および着脱部４０側にない二つの辺部の所定の位置に、それぞれ不正開放防止結合手段を構成する複数の重合結合部５０〜５３，５４〜５７が形成される。
【００３３】
重合結合部５０〜５３、５４〜５７は、それぞれ図５のように上蓋部材２６の周壁３８ｂ，３８ｃから突出させた連結部（上方連結部）６０の先端に上方結合部６１が、ベース部材２５の周壁３５ｂ，３５ｃから突出させた連結部（下方連結部）６２の先端に下方結合部６３が形成される。
【００３４】
上方結合部６１には、中央に所定径の通し穴６４が、通し穴６４の上部にワンウェイネジ６５等（締結部材）の頭部を囲う埋め込み穴６６が、下面に通し穴６４の回りに段状の係合突部６７が設けられる。下方結合部６３には、上部に上方結合部６１の係合突部６７が嵌まる係合受部６８が、その中央に上方結合部６１の通し穴６４につながる通し穴６４とほぼ同径の所定深さの穴６９が形成される。上蓋部材２６をベース部材２５に対して閉じると、図６のように上方結合部６１の係合突部６７が下方結合部６３の係合受部６８に嵌まり、位置決めしながら、上方結合部６１の下面と下方結合部６３の上面が、上方連結部６０の下面と下方連結部６２の上面が当接される。
【００３５】
重合結合部５０〜５３は、上蓋部材２６の周壁３８ｂ、ベース部材２５の周壁３５ｂに沿って１列に所定の間隔を空けて形成され、重合結合部５４〜５７は、上蓋部材２６の周壁３８ｃ、ベース部材２５の周壁３５ｃに沿って１列に所定の間隔を空けて、この場合周壁３８ｂ、周壁３５ｂに近い側に形成される。重合結合部５０〜５３，５４〜５７をそれぞれ所定の間隔を空けて形成することにより、ニッパ等での切断が容易になり、検査時の作業性が向上する。
【００３６】
ベース部材２５の周壁３５ａ，３５ｃには取付ボス７２が突設され、その取付ボス７２には裏メカベース盤１０の取付部に設けた掛止具に対するワンタッチ式の止め具７３（図２）が組み込まれる。
【００３７】
図７〜図９に示すように、重合結合部５０〜５３、５４〜５７の上方連結部６０の断面形状は幅の狭い長方形に、下方連結部６２の断面形状はそれより幅の大きい方形に形成される。これらの幅は図９の左右方向の長さを言う。
【００３８】
下方連結部６２が上方連結部６０に隠れることのないように、下方連結部６２の外形幅が上方連結部６０の外形幅よりも大きく形成される。即ち、上蓋部材２６をベース部材２５に対して閉じた状態にて、上蓋部材２６側から連結部６０，６２を見たときに、両方の連結部６０，６２の状態が視認可能に形成される。
【００３９】
この場合、上方連結部６０の断面形状は長方形でなくても良く、下方連結部６２の断面形状は方形でなくても良い。また、これらの断面形状は曲形状、傾斜形状を持つものでも良い。また、連結部６０，６２の断面形状は山型形状あるいは図１０のように大きさの異なる台形状でも良い。また、上方連結部６０は下方連結部６２の上方に位置せずとも良い。上蓋部材２６側から両方の連結部６０，６２の状態が視認可能であれば、どのような形状でも良い。
【００４０】
なお、上方連結部６０、下方連結部６２の断面積は、同じでも、どちらが大きくても良いが、それぞれニッパ等で切断可能な大きさに形成される。
【００４１】
上蓋部材２６の天板部４４の表面には、図７のように後述する確認部材８０，８１が取付けられると共に、重合結合部５０〜５３，５４〜５７の近傍に、それぞれ重合結合部５０〜５３，５４〜５７に対応して数字等の識別記号が印刷あるいは打刻（成型表示を含む）される。重合結合部５０〜５３，５４〜５７をそれぞれ左から順に組み合わせ、例えば重合結合部５３，５４に対応して１の識別記号が、重合結合部５２，５５に対応して２の識別記号が、重合結合部５１，５６に対応して３の識別記号が、重合結合部５０，５７に対応して４の識別記号が表示される。
【００４２】
次に、基板ボックス１５の組立ておよび遊技機への組付けについて説明する。
【００４３】
ベース部材２５の底部３４に下部保護板２７、制御回路基板３０、上部保護板２８を重ね、ネジにより止着用ボス３６にネジ止めする。
【００４４】
上蓋部材２６の重合結合部５０〜５３、５４〜５７の上方結合部６１の通し穴６４には、それぞれ締め方向しか回せないワンウェイネジ６５を、ワンウェイネジ６５の先端が通し穴６４から下面に出ないように仮止めしておく。
【００４５】
この場合、ワンウェイネジ６５の深さを設定するために、ワンウェイネジ６５を締めるドライバ工具等に締め付け深さを調整するストッパ等の調整機構を設けて、ワンウェイネジ６５を仮止めするようにすると良い。ワンウェイネジ６５を一旦締めると元に戻せないが、このようにすれば、ワンウェイネジ６５を適度な深さに仮止めでき、仮止めを容易に行える。
【００４６】
この上蓋部材２６とベース部材２５との蝶着部４０を掛け合わせ、上蓋部材２６を閉じる。この際、上蓋部材２６とベース部材２５との係止部４３の突起４１が係止片４２に嵌まって、上蓋部材２６がベース部材２５に係止され、位置決めされると共に、重合結合部５０〜５３、５４〜５７の各上方結合部６１の係合突部６７が各下方結合部６３の係合受部６８に嵌まり、それぞれが位置決めしながら、重合する。
【００４７】
この状態にて、重合結合部５０〜５３のうちの一つと、重合結合部５４〜５７のうちの一つとを、それぞれ上方結合部６１に仮止めしてあるワンウェイネジ６５を下方結合部６３まで確実に締めて、結合、固着する。この場合、識別記号１の重合結合部５３，５４を結合、固着する。
【００４８】
結合、固着した重合結合部５３，５４の上方結合部６１の埋め込み穴６６には、ワンウェイネジ６５の頭部を隠すように図１１のような結合蓋部材７４を装着する。その他の重合結合部５０〜５２，５５〜５７の上方結合部６１の埋め込み穴６６には、ドライバの差し込み穴７６を設けた図１２のような仮止め結合蓋部材７５を装着する。なお、埋め込み穴６６には結合蓋部材７４，７５の突起７７に掛止する溝を設けてある。ワンウェイネジ６５の頭部を隠すことで、一度封印されたワンウェイネジ６５の頭部は、不正行為者に触られることがなくなり、例えばラジオペンチ等で無理やり緩む方向へと回されるといった不正な行為を予防することが可能となる。そして、仮止め結合蓋部材７５は、仮止めされたワンウェイネジ６５の上部をふさぐようにするので、仮止めされたワンウェイネジ６５が遊技機の運搬途中等で何らかの拍子に重合結合部から落下するのを防ぎながら、検査時に重合結合部の固着をする際に差し込み穴７６にドライバの先端を差し込むことで仮止め状態から固着状態にすることが可能となる。また、仮止め結合蓋部材７５は、差し込み穴７６が設けられているが、この穴を設けずに、取付け、取り外しを自在にして、これを取り外してから仮止めされているワンウェイネジ６５を固着するようにしても良い。
【００４９】
この後、基板ボックス１５の表面つまり上蓋部材２６の天板部４４の表面には、図７のように透明なシール等に遊技機メーカー名、機種名、電圧、容量、注意書き等を記載した第１の確認部材８０、ならびに所定のシール等に製造業者記号を含んだ基板管理番号を記載（図示してない）すると共に公的機関が検査の際に基板ボックス１５を正規に開放したことを証明する記載を可能な欄つまり検査回数、検査年月日、検査印等の検査履歴の記載欄を設けた第２の確認部材８１を取付ける。
【００５０】
第１の確認部材８０は、上蓋部材２６の天板部４４の蝶着部４０側に、第２の確認部材８１は天板部４４の重合結合部５４〜５７に沿う側に、貼着により取付ける。
【００５１】
この場合、第１の確認部材８０は、樹脂等のプレートに遊技機メーカー名、…、注意書き等を印刷あるいは打刻（成型表示を含む）したものを、上蓋部材２６の天板部４４に接着、あるいは天板部４４に嵌め込み溝等の取付部を形成して、取付けるようにして良い。また、遊技機メーカー名、…、注意書き等を予め天板部４４に打刻するようにしても良い。
【００５２】
第２の確認部材８１は、検査履歴の記載欄等を設けたシールを樹脂等のプレートに貼り付けると共に、上蓋部材２６の天板部４４にそのプレートを着脱できる嵌め込み溝等の取付部を形成して、取付けるようにして良い。また、検査時の開、封の手順等の説明をシールあるいはプレートに印刷あるいは打刻により表記するようにして良い。また、シールを用いる場合、剥がすと痕跡が残る特殊なシールを用いて良い。
【００５３】
また、第２の確認部材８１の検査回数の欄には、上蓋部材２６の天板部４４に表示してある重合結合部５０〜５３，５４〜５７の識別記号１，２，３，４に対応して、第１、第２、第３、第４の表示の印刷等を行っておく。このように、重合結合部５０〜５３，５４〜５７の識別記号に検査履歴の欄を対応させれば、重合結合部５０〜５３，５４〜５７の封印順序が定まり、識別記号、検査履歴を見て、重合結合部の状態を的確に照合でき、正規の重合結合部が固着してあるか、不正に切除してあるかが容易に分かる。
【００５４】
なお、第１の確認部材８０、第２の確認部材８１は、上蓋部材２６の天板部４４の内面に、つまり確認部材８０，８１の表面を天板部４４の表面（外面）に向けて取付けるようにしても良い。この場合、埃等によって確認部材８０，８１が汚れたり、表示が見えにくくなるようなことはなく、また確認部材８０，８１が剥がれたり、傷付いたりするようなこともない。
【００５５】
そして、このように組立てた基板ボックス１５を図２のように遊技機の裏メカベース盤１０の所定の取付位置に取付ける。
【００５６】
基板ボックス１５のベース部材２５を裏メカベース盤１０の所定の取付位置の表面に合わせ、ベース部材２５の取付ボス７２のワンタッチ式の止め具７３を裏メカベース盤１０の所定位置の掛止具に押し込み、固定する。
【００５７】
この場合、図２のように重合結合部５４〜５７が上方に、制御回路基板３０の配線コード群の接続領域３３が球排出制御装置１３側に、重合結合部５０〜５３が裏メカベース盤１０の周縁部につまり遊技機の前面枠１の開閉自由端側にくるように、取付位置を定めている。
【００５８】
この取付後、制御回路基板３０の配線コード群の接続領域３３のコネクタ部３２に、表示制御装置１２、球排出制御装置１３、各種電気機器からの配線コード群１７〜２０のコネクタ端をそれぞれ嵌め込み、接続する。
【００５９】
この際、接続領域３３に対する配線コード群１７〜２０の配線作業空間が重ならない基板ボックス１５の部位に重合結合部５０〜５３、５４〜５７が位置している。即ち、重合結合部５０〜５３は、接続領域３３の反対側にて裏メカベース盤１０の周縁部側に、重合結合部５４〜５７は、接続領域３３から離れ裏メカベース盤１０の周縁部に近い側に位置する。このため、配線コード群１７〜２０を接続領域３３のコネクタ部３２に接続する場合に、重合結合部５０〜５３，５４〜５７に配線が絡まったり、接続した配線が重合結合部５０〜５３，５４〜５７を覆って重合結合部５０〜５３，５４〜５７が隠れたりすることはない。
【００６０】
このように、組立て、組付けを行うのであり、公的機関による基板ボックス１５内の制御回路基板３０のＲＯＭ３１の検査を行うときは、遊技機の裏メカベース盤１０より基板ボックス１５を外して、あるいは裏メカベース盤１０に取付けたまま、基板ボックス１５を開ける。
【００６１】
基板ボックス１５を取り外す際は、まず配線コード群１７〜２０を接続領域３３のコネクタ部３２より外し、ベース部材２５のワンタッチ式の止め具７３を引くと、外せる。このとき、配線作業空間が重合結合部５０〜５３，５４〜５７に重ならないため、重合結合部５０〜５３，５４〜５７に配線が絡まって、取り外しがしにくかったり、配線や重合結合部５０〜５３，５４〜５７を傷つけるようなことはない。
【００６２】
基板ボックス１５を取り外すと、重合結合部５０〜５３，５４〜５７のうち、ワンウェイネジ６５によって固着してある識別記号１の重合結合部５３，５４の上方連結部６０、下方連結部６２をニッパ等で切断して、その重合結合部５３，５４を取り除く。この場合、上方連結部６０、下方連結部６２の両方を確実に切断する。
【００６３】
この重合結合部５３，５４を除くと、上蓋部材２６は係止部４３によって閉止しているだけのため、係止部４３を外せば、上蓋部材２６が開く。
【００６４】
上蓋部材２６を開くと、制御回路基板３０のＲＯＭ３１を外して検査を行うことになる。
【００６５】
検査を終了すると、ＲＯＭ３１を制御回路基板３０に装着して上蓋部材２６を閉じる。この際、上蓋部材２６が位置決めしながら係止部４３が係止する。同時に、切除していない識別記号２〜４の重合結合部５０〜５２，５５〜５７の各上方結合部６１の係合突部６７が各下方結合部６３の係合受部６８に嵌まり、位置決めする。
【００６６】
この状態にて、識別記号２の重合結合部５２，５５の上方結合部６１に仮止めしてあるワンウェイネジ６５を下方結合部６３まで締めて、その重合結合部５２，５５を結合、固着する。上蓋部材２６を閉じると、識別記号２〜４の重合結合部５０〜５２，５５〜５７の各上方結合部６１の係合突部６７が各下方結合部６３の係合受部６８に嵌まり、位置決めする。即ち、識別記号２〜４の重合結合部５０〜５２，５５〜５７が確実に重合するため、識別記号２の重合結合部５２，５５の結合、固着が容易になり、不完全な状態でワンウェイネジ６５を締める心配はない。
【００６７】
この後、上蓋部材２６の天板部４４の第２の確認部材８１の検査回数の第１の記載欄に、検査担当者が検査年月日の記入、検査印等の捺印を行った後、基板ボックス１５を遊技機の裏メカベース盤１０の取付位置に合わせ、ベース部材２５のワンタッチ式の止め具７３を押し込み、取付ける。
【００６８】
取付後は、制御回路基板３０の接続領域３３のコネクタ部３２に配線コード群１７〜２０を接続して完了となる。
【００６９】
また、基板ボックス１５を裏メカベース盤１０に取付けたまま、検査を行う場合は、そのままニッパ等で、重合結合部５０〜５３，５４〜５７のうち、ワンウェイネジ６５によって固着してある識別記号１の重合結合部５３，５４の上方連結部６０、下方連結部６２をニッパ等で切断して、その重合結合部５３，５４を取り除く。配線コード群１７〜２０が重合結合部５０〜５３，５４〜５７から離れているため、重合結合部５３，５４を切除する際に配線を一緒に切断するようなことはない。
【００７０】
この状態にて、係止部４３を外すと、上蓋部材２６が開き、制御回路基板３０からＲＯＭ３１を外して検査を行う。
【００７１】
検査を終了すれば、ＲＯＭ３１を制御回路基板３０に装着して上蓋部材２６を閉じ、この際係止部４３によって上蓋部材２６は位置決めすると共に、識別記号２〜４の重合結合部５０〜５２，５５〜５７の各上方結合部６１の係合突部６７が各下方結合部６３の係合受部６８に嵌まり、位置決めしながら、識別記号２〜４の重合結合部５０〜５２，５５〜５７が確実に重合するため、上蓋部材２６を閉じると、そのまま識別記号２の重合結合部５２，５５の上方結合部６１に仮止めしてあるワンウェイネジ６５を下方結合部６３まで締めて、その重合結合部５２，５５を結合、固着する。重合結合部５２，５５は配線コード群１７〜２０から離れているため、その結合、固着を容易に行える。
【００７２】
後は、上蓋部材２６の天板部４４の第２の確認部材８１の検査回数の第１の記載欄に、検査担当者が検査年月日の記入、検査印等の捺印を行えば、完了となる。
【００７３】
一方、不正行為として、基板ボックス１５を不正に開けて、制御回路基板３０のＲＯＭ３１を不正なＲＯＭに交換、あるいはＲＯＭ３１のデータを書き換えて、大当たりを頻繁に発生させる等の不正行為がある。
【００７４】
この不正行為には、正規に固着してある重合結合部の上方連結部６０と下方連結部６２とを切断して、その重合結合部を取り除いて、基板ボックス１５を開けたりすることが想定される。
【００７５】
また、上方連結部６０のみを切断して、重合結合部を取り除かずに、基板ボックス１５を開けたり、あるいは切断部分を隠蔽するように、上方連結部６０は切断せずに下側の下方連結部６２のみを切断して、基板ボックス１５を開けたりすることが想定される。
【００７６】
しかし、重合結合部が取り除かれた場合、また上方連結部６０あるいは下方連結部６２のどちらかが切断された場合、これらは遊技店における遊技機の保守点検時あるいは営業中に遊技機の球詰まり等を直す際等に、発見できる。
【００７７】
基板ボックス１５を遊技機の裏面に取付けるため、遊技機の裏側から重合結合部５０〜５３，５４〜５７を確認できると共に、重合結合部５０〜５３，５４〜５７の上方連結部６０の状態および下方連結部６２の状態を上蓋部材２６側から視認可能なため、基板ボックス１５の取付部のほぼ正面側から即ち遊技機の裏側から、図７のように重合結合部５０〜５３，５４〜５７の上方連結部６０の状態および下方連結部６２の状態の両方を視認できる。また、基板ボックス１５を取付けた状態において、図２のように重合結合部５０〜５３が遊技機の前面枠１の開閉自由端側に、重合結合部５４〜５７が基板ボックス１５の上部にあり、また接続領域３３の配線に隠れることがないので、係員の目に入りやすい。
【００７８】
そのため、遊技機の前面枠１を開くと、正規の重合結合部が切除されていれば、これをすぐに見付けることができる。
【００７９】
また、上方連結部６０が切断されている場合、固着してある重合結合部が取り除かれていなくとも、その切断の跡が見えるため、上方連結部６０が切断されていることが容易に分かる。
【００８０】
また、上方連結部６０の下側の下方連結部６２も視認できるため、図１３、図１４のように重合結合部５２，５５の上方連結部６０が切断されずに下方連結部６２のみが切断されている場合（重合結合部５３，５４は正規な切除）に、その切断の跡が目に入り、下側の下方連結部６２が切断されていることを容易に見付けることができる。即ち、下方連結部６２だけを切断して開封したことを分かりにくくしようとする隠蔽行為に対処できる。
【００８１】
基板ボックス１５の上蓋部材２６の天板部４４に重合結合部５０〜５３，５４〜５７の識別記号を表示すると共に、天板部４４に取付けてある第２の確認部材８１にその識別記号に対応する検査履歴の欄を設けるため、その識別記号、検査履歴を見て、固着してある重合結合部が正しいものかどうか、不正な切除かどうかの照合を簡単に行え、不正を容易に見付けることができる。
【００８２】
基板ボックス１５の複数の箇所に重合結合部５０〜５３，５４〜５７を形成して、複数の重合結合部を封印するので、封印効果が高まることに加え、不正を発見しやすい。
【００８３】
このように、基板ボックス１５を取り外さずに、遊技機の裏側から基板ボックス１５の重合結合部５０〜５３，５４〜５７、これらの上方連結部６０、下方連結部６２の状態、および第１の確認部材８０、第２の確認部材８１の記載内容を視認できるのであり、不正行為があっても、遊技機の保守点検時あるいは営業中に遊技機の球詰まり等を直す際等に簡単にかつ早期に発見できる。このため、不正抑止を図れる。
【００８４】
したがって、重合結合部を切除して基板ボックス１５を開け、制御回路基板３０のＲＯＭ３１を不正に交換する等の不正行為を防止でき、このような不正行為による遊技店の損害を最小限に抑えることができる。
【００８５】
また、基板ボックス１５の遊技機への取付け、取り外し時に、重合結合部５０〜５３，５４〜５７に配線が絡んだりすることがないため、その取付け、取り外しが容易であり、また公的機関による検査時に、基板ボックス１５を遊技機から取り外して検査を行う場合、その取り外し、取付け作業が容易であり、検査をスムーズに行える。
【００８６】
基板ボックス１５の上蓋部材２６とベース部材２５とに設けた蝶着部４０と係止部４３とによって、重合結合部を切除する際、あるいは重合結合部のワンウェイネジ６５を締める際に、上蓋部材２６やベース部材２５が動いたりすることはなく、重合結合部の切除、ワンウェイネジ６５の締結を行いやすくなる。
【００８７】
蝶着部４０と係止部４３と、重合結合部５０〜５３，５４〜５７の上方結合部６１と下方結合部６３とに設けた係合部６７，６８とによって、上蓋部材２６を閉じれば、重合結合部５０〜５３，５４〜５７がそれぞれ確実に重合して位置合わせが容易に行え、ワンウェイネジ６５によって該当する重合結合部の結合、固着を確実に行える。
【００８８】
公的機関による検査時に、基板ボックス１５を遊技機から取り外さずに検査を行える。この際、固着してある重合結合部を切除して、係止部４３を外せば、上蓋部材２６が簡単に開くと共に、上蓋部材２６は蝶着部４０によって手前下方に開いた状態を保つので、制御回路基板３０からＲＯＭ３１を簡単に外せる。また、検査終了後にＲＯＭ３１を簡単に装着できる。
【００８９】
したがって、基板ボックス１５の遊技機への取付け、取り外し作業、基板ボックス１５の開放、封印作業、検査作業を容易に行え、作業性の向上を図れる。
【００９０】
なお、重合結合部５０〜５３，５４〜５７の締結部材として、ワンウェイネジ６５を用いたが、リベットを用いても良く、また重合結合部の構造を含め、切断あるいは切除しなければ、基板ボックス１５を開けられないものであれば、何でも良い。
【００９１】
また、基板ボックス１５の上蓋部材２６、ベース部材２５の周壁３８ｂ，３５ｂ，３８ｃ，３５ｃの二カ所に、即ち上蓋部材２６側から見て複数ある辺部のうち二つの辺部に重合結合部５０〜５３，５４〜５７を形成したが、そのうちの一方にのみ形成しても良い。
【００９２】
また、実施の形態では、役物制御装置の基板ボックスに適用した例を示したが、遊技プログラムを記憶したＲＯＭと同じような重要部品を持つものであれば、これに限定することなく適用できる。また、基板ボックスは、一つの役物制御装置だけでなく、球排出制御装置あるいはその他の制御装置を収容するものであって良い。
【００９３】
図１５〜図１８は別の実施の形態を示すもので、重合結合部５０〜５３，５４〜５７のそれぞれ上方連結部９０と下方連結部９１とに、連結部同士が嵌合する嵌合部９２を形成したものである。
【００９４】
上方連結部９０は、断面形状が幅（図１７、図１８の左右方向の長さを言う）の狭い長方形に形成され、下方連結部９１は、上部に上方連結部９０に対応する溝９３が形成される。この溝９３の両側の壁９４は、下方結合部６３の上面より上方に突出して形成される。
【００９５】
したがって、上蓋部材２６をベース部材２５に対して閉じた状態にて、図１７のように上方連結部９０が下方連結部９１の溝９３に嵌合される。
【００９６】
このようにすれば、上蓋部材２６側から連結部９０，９１を見たときに、両方の連結部９０，９１の状態を視認できると共に、嵌合によって上方連結部９０、下方連結部９１の片側のみを切断するのが難しくなり、不正行為の防止効果が高まる。
【００９７】
なお、下方連結部９１の溝９３を深くし、上方連結部９０の下部を上方結合部６１よりも下方に突出させる形状にしても良い。また、上方連結部９０、下方連結部９１の断面形状は曲形状、傾斜形状を持つものでも良い。
【００９８】
図１９〜図２２は別の実施の形態を示すもので、上蓋部材２６をベース部材２５に対して閉じた状態にて、上蓋部材２６側から重合結合部５０〜５３，５４〜５７の上方連結部９５、下方連結部９６を見たときに、それぞれ上方連結部９５、下方連結部９６が対称位置に見えるように形成し、連結部９５、連結部９６の状態を視認できるようにしたものであり、連結部９５、連結部９６がそれぞれ直接的に視認できるので切断痕が容易に認識できる。
【００９９】
図２１、図２２のように上方連結部９５は上方結合部６１に対して左側に偏心して形成され、下方連結部９６は下方結合部６３に対して右側に偏心して形成される。即ち、互い違いに形成される。この場合、連結部９５，９６に重なる部分があっても良い。
【０１００】
このようにすれば、下方連結部９６を小さくできる。また、上方連結部９５、下方連結部９６の形状は特に限定されない。
【０１０１】
なお、各実施の形態において、上方連結部、下方連結部の断面形状は一定でなくても良い。
【０１０２】
また、遊技機としてパチンコ遊技機に適用した例を示したが、その他の遊技機、例えばパチスロ、アレンジボール等の遊技機にも適用できる。
【０１０３】
【発明の効果】
以上のように第１の発明によれば、制御回路基板を収容する基板ボックスの上蓋部材とベース部材との対向部位に、上蓋部材とベース部材とから各々突出させた連結部を介して重合する重合結合部を複数形成して、このうちの一つを締結部材により固着することで、基板ボックスが開放不能に閉止されると共に、ベース部材から突出させた下方連結部の断面外形幅が、上蓋部材から突出させた上方連結部の断面外形幅よりも大きく設定される。したがって、基板ボックスを遊技機の所定位置に取付けた状態において、ベース部材側の連結部の状態を視認しやすくなり、下方連結部が切断されているかどうかが容易に把握できる。
【０１０４】
このため、重合結合部により基板ボックスを破壊せずに開放、封印できると共に、例えば大当たりを不正に発生させるために、正規に固着してある重合結合部の連結部を切断して、基板ボックスを開けてしまい、制御回路基板のＲＯＭを不正なＲＯＭに交換、あるいはＲＯＭのデータを書き換える不正行為が行われることがあっても、これは遊技店における遊技機の保守点検時あるいは営業中に遊技機の球詰まり等を直す際等、容易に発見される。この場合、基板ボックスを開けたことを分かりにくくするために、重合結合部の上蓋部材側の連結部を切断せずにベース部材側の連結部のみが切断されることがあるが、このような隠蔽行為にあっても、ベース部材側の連結部の状態が視認され、把握できるため、その連結部の切断による不正も容易に速やかに発見される。したがって、不正の抑止にもなり、不正を防止できる。また、上蓋部材側の連結部をベース部材側の連結部に形成した溝に嵌合するので、片側の連結部のみを切断するのが難しくなり、不正行為の一層の防止を図れる。
【０１０６】
第２の発明によれば、基板ボックスを閉止する際、上方結合部に形成した係合突部と下方結合部に形成した係合突部とにより重合結合部が確実に重合するので、締結部材による重合結合部の固着を容易かつ的確に行えると共に、上方連結部と下方連結部とを、基板ボックスを遊技機の所定位置に取付けた状態においてほぼ正面側から視認可能に互い違いに形成したので、上方連結部と下方連結部の一方を切断しての基板ボックスの不正な開放も容易に発見することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a board box that houses a control circuit board of a gaming machine.
[0002]
[Prior art]
In a conventional gaming machine, for example, a pachinko gaming machine, a control circuit such as an accessory control device that controls the gaming machine or a ball discharge control device that controls the ball discharge device is housed in the box on the back side of the game machine. A substrate box is provided.
[0003]
The board box contains a control circuit board on which a large number of electronic components such as IC (integrated circuit) and resistors are mounted in a resin or metal box to prevent short-circuiting or dust and other dust from entering. And can be attached to the back side of a main frame (front frame) of the gaming machine, a back mechanical base board as a base frame, or a game board.
[0004]
For example, in an accessory control device, a CPU, ROM (memory), RAM (memory), etc. are provided in a control circuit, game control is performed according to a program stored in the ROM, and jackpots are also here. It is controlled.
[0005]
The board box is generally a box body in which an upper lid member and a base member are overlapped, and a connector part for electrical connection with other various devices is provided exposed from the box. By inserting the wiring into the connector portion, it is possible to control each of them.
[0006]
For fraudulent acts on the board box, remove the upper cover member, replace the electronic parts such as ROM provided on the opened control circuit board, or rewrite the data (for example, set the jackpot probability higher than usual) By performing this, compared to the normal game control, for example, illegal game control such as frequent appearance of jackpots is performed.
[0007]
For this reason, in the substrate box, a seal is put on the joint between the upper lid member and the base member so that it can be seen that the substrate box is opened, or the surface of the substrate box is formed of a clear resin. Thus, the state of the accommodated control circuit board is made visible from the outside.
[0008]
[Problems to be solved by the invention]
However, in the conventional substrate box, since the upper lid member and the base member are structurally assembled only by screws, it is easy to remove the upper lid member and open the box body. Even if a seal sticker is put on the seam, this is effective for easy fraudsters, but for very professional fraudsters, such as those with fake seal stickers or special release materials. On the other hand, the fact is that the effect is lost.
[0009]
In general, a fraudulent person crafts a craft so that even if the board box is unsealed, it cannot be seen in a state where it is installed in a gaming machine in order to deceive the unsealing. For example, the board box is forcibly opened from a portion that cannot be seen from the back side of the gaming machine, or the opened place is hidden. Moreover, in the person who has said false seal seal, a false seal is affixed from the trace which peeled off the seal seal.
[0010]
In order to prevent these fraudulent acts, it may be possible to make the board box a structure that cannot be opened or very difficult to open. Inspection of whether or not it is an illegal board is performed by a target organization (the police, etc.). As the inspection contents, an inspection is performed such that the program data stored in the ROM is read by the data loader and compared with the regular ROM. In this case, if the substrate box cannot be opened as described above, the inspection is performed. It becomes impossible. For this reason, it is conceivable to destroy and open the substrate box. However, if the substrate box is destroyed, it cannot be reused after inspection.
[0011]
Accordingly, an object of the present invention is to prevent unauthorized opening of a board box containing a control circuit board, and to enable opening during inspection and repair, and to easily open the board box. It is an object of the present invention to provide a board box for a gaming machine that can be discriminated and can prevent fraud.
[0012]

[0052]
The second confirmation member 81 forms a mounting portion such as a fitting groove on which the plate can be attached to and detached from the top plate portion 44 of the upper lid member 26 while sticking a seal provided with an inspection history description column or the like to a plate of resin or the like. And you may make it attach. In addition, a description of opening and sealing procedures at the time of inspection may be written on a sticker or plate by printing or stamping. Moreover, when using a seal | sticker, you may use the special seal | sticker in which a trace remains when it peels.
[0053]
In the column of the number of inspections of the second confirmation member 81, the identification symbols 1, 2, 3, and 4 of the superposition bonding parts 50 to 53 and 54 to 57 displayed on the top plate part 44 of the upper lid member 26 are displayed. Correspondingly, printing of the first, second, third, and fourth displays is performed. In this way, if the column of the inspection history is made to correspond to the identification symbols of the polymerization bonding portions 50 to 53 and 54 to 57, the sealing order of the polymerization bonding portions 50 to 53 and 54 to 57 is determined, and the identification symbols and the inspection history are displayed. The state of the superposition | polymerization coupling | bond part can be collated exactly, and it can be understood easily whether the regular superposition | polymerization coupling | bond part has adhered or it cut off illegally.
[0054]
The first confirmation member 80 and the second confirmation member 81 are directed to the inner surface of the top plate portion 44 of the upper lid member 26, that is, the surfaces of the confirmation members 80 and 81 are directed to the surface (outer surface) of the top plate portion 44. You may make it attach. In this case, the confirmation members 80 and 81 are not soiled by dust or the display is not easily seen, and the confirmation members 80 and 81 are not peeled off or damaged.
[0055]
Then, the assembled board box 15 is attached to a predetermined attachment position of the back mechanical base board 10 of the gaming machine as shown in FIG.
[0056]
The base member 25 of the board box 15 is aligned with the surface of the back mechanical base board 10 at a predetermined mounting position, and the one-touch type stopper 73 of the mounting boss 72 of the base member 25 is pushed into the hook at the predetermined position of the back mechanical base board 10. , Fix.
[0057]
In this case, as shown in FIG. 2, the superposition coupling portions 54 to 57 are directed upward, the connection region 33 of the wiring cord group of the control circuit board 30 is on the ball discharge control device 13 side, and the superposition coupling portions 50 to 53 are on the back mechanical base board 10. The attachment position is determined so as to come to the peripheral edge of the front frame 1, that is, the open / close free end side of the front frame 1 of the gaming machine.
[0058]
After this attachment, the connector ends of the wiring cord groups 17 to 20 from the display control device 12, the ball discharge control device 13, and various electric devices are fitted into the connector portions 32 of the connection region 33 of the wiring cord group of the control circuit board 30. ,Connecting.
[0059]
Under the present circumstances, the superposition | bonding coupling | bond part 50-53, 54-57 is located in the site | part of the board | substrate box 15 where the wiring work space of the wiring code groups 17-20 with respect to the connection area | region 33 does not overlap. In other words, the overlapping bonding portions 50 to 53 are on the side of the peripheral portion of the back mechanical base board 10 on the opposite side of the connection region 33, and the overlapping bonding portions 54 to 57 are apart from the connection region 33 and close to the peripheral portion of the back mechanical base plate 10. Located on the side. For this reason, when connecting the wiring cord groups 17 to 20 to the connector portion 32 of the connection region 33, the wires are entangled with the overlapping bonding portions 50 to 53 and 54 to 57, or the connected wires are overlapped with the overlapping bonding portions 50 to 53, The superposition | polymerization coupling | bond part 50-53 and 54-57 do not cover 54-57.
[0060]
In this way, assembly and assembly are performed, and when the ROM 31 of the control circuit board 30 in the board box 15 is inspected by a public institution, the board box 15 is removed from the back mechanical base board 10 of the gaming machine, Alternatively, the substrate box 15 is opened while being attached to the back mechanical base board 10.
[0061]
When removing the board box 15, the wiring cord groups 17 to 20 are first removed from the connector portion 32 of the connection region 33, and can be removed by pulling the one-touch type stopper 73 of the base member 25. At this time, since the wiring work space does not overlap with the superposition coupling parts 50 to 53 and 54 to 57, the superposition of the superposition coupling parts 50 to 53 and 54 to 57 makes it difficult to remove the wiring work space or the superposition coupling part 50. There is no such thing as hurting ~ 53, 54 ~ 57.
[0062]
When the substrate box 15 is removed, the upper connecting portion 60 and the lower connecting portion 62 of the overlapping portions 53 and 54 of the identification symbol 1 fixed by the one-way screw 65 among the overlapping portions 50 to 53 and 54 to 57 are nippered. The superposition | polymerization coupling | bond part 53,54 is removed by cut | disconnecting by the above. In this case, both the upper connecting part 60 and the lower connecting part 62 are reliably cut.
[0063]
Except for the overlapping portions 53 and 54, the upper lid member 26 is only closed by the latching portion 43. Therefore, if the latching portion 43 is removed, the upper lid member 26 is opened.
[0064]
When the upper lid member 26 is opened, the inspection is performed with the ROM 31 of the control circuit board 30 removed.
[0065]
When the inspection is completed, the ROM 31 is mounted on the control circuit board 30 and the upper lid member 26 is closed. At this time, the locking portion 43 is locked while the upper lid member 26 is positioned. At the same time, the engagement protrusions 67 of the upper coupling portions 61 of the superposed coupling portions 50 to 52 and 55 to 57 of the identification symbols 2 to 4 that are not excised fit into the engagement receiving portions 68 of the lower coupling portions 63, respectively. Position.
[0066]
In this state, the one-way screw 65 temporarily fixed to the upper coupling portion 61 of the polymerization coupling portion 52, 55 of the identification symbol 2 is tightened to the lower coupling portion 63, and the polymerization coupling portions 52, 55 are coupled and fixed. . When the upper lid member 26 is closed, the engagement protrusions 67 of the upper coupling portions 61 of the overlapping coupling portions 50 to 52 and 55 to 57 of the identification symbols 2 to 4 are fitted into the engagement receiving portions 68 of the lower coupling portions 63. , Positioning. That is, since the polymerization bond portions 50 to 52 and 55 to 57 with the identification symbols 2 to 4 are surely polymerized, the polymerization bond portions 52 and 55 with the identification symbol 2 can be easily bonded and fixed, and one-way in an incomplete state. There is no worry of tightening the screw 65.
[0067]
After this, after the person in charge of the inspection enters the date of inspection, the inspection mark, etc. in the first description column of the number of inspections of the second confirmation member 81 of the top plate portion 44 of the top cover member 26, The board box 15 is aligned with the attachment position of the back mechanical base board 10 of the gaming machine, and the one-touch type stopper 73 of the base member 25 is pushed in and attached.
[0068]
After the attachment, the wiring cord groups 17 to 20 are connected to the connector portion 32 of the connection region 33 of the control circuit board 30 to complete.
[0069]
Further, when the inspection is performed with the substrate box 15 being attached to the back mechanical base board 10, the identification symbol 1 fixed by the one-way screw 65 of the overlapped bonding portions 50 to 53 and 54 to 57 is directly used by a nipper or the like. The upper coupling portion 60 and the lower coupling portion 62 of the polymerization coupling portions 53 and 54 are cut with a nipper or the like, and the polymerization coupling portions 53 and 54 are removed. Since the wiring cord groups 17 to 20 are separated from the overlapping portions 50 to 53 and 54 to 57, the wires are not cut together when the overlapping portions 53 and 54 are cut off.
[0070]
In this state, when the latching portion 43 is removed, the upper lid member 26 is opened, and the ROM 31 is removed from the control circuit board 30 for inspection.
[0071]
When the inspection is completed, the ROM 31 is mounted on the control circuit board 30 and the upper lid member 26 is closed. At this time, the upper lid member 26 is positioned by the locking portion 43 and the overlapping coupling portions 50 to 52 of the identification symbols 2 to 4 are provided. While the engaging protrusions 67 of the upper coupling portions 61 of 55 to 57 are fitted and positioned in the engagement receiving portions 68 of the lower coupling portions 63, the overlapping coupling portions 50 to 52, 55 of the identification symbols 2 to 4 are positioned. When the upper lid member 26 is closed, the one-way screw 65 temporarily fixed to the upper coupling portion 61 of the superposition coupling portion 52, 55 of the identification symbol 2 is tightened to the lower coupling portion 63. The polymerization bonding parts 52 and 55 are bonded and fixed. Since the superposition | bonding coupling parts 52 and 55 are separated from the wiring cord groups 17-20, the coupling | bonding and fixation can be performed easily.
[0072]
After that, if the person in charge of the inspection fills in the first description column of the number of inspections of the second confirmation member 81 of the top plate part 44 of the top cover member 26, the inspection date is completed and the inspection mark is printed. It becomes.
[0073]
On the other hand, as an illegal act, there is an illegal act such as opening the board box 15 illegally, replacing the ROM 31 of the control circuit board 30 with an illegal ROM, or rewriting data in the ROM 31 to frequently generate jackpots.
[0074]
In this fraudulent act, it is assumed that the upper connecting portion 60 and the lower connecting portion 62 of the polymerization bonding portion that is properly fixed are cut, the polymerization bonding portion is removed, and the substrate box 15 is opened. The
[0075]
In addition, the upper connection portion 60 is not cut and the upper lower connection portion 60 is not cut so that the substrate box 15 is opened or the cut portion is concealed without cutting only the upper connection portion 60 and removing the polymerization bond portion. It is assumed that only the part 62 is cut and the substrate box 15 is opened.
[0076]
However, when the superposition bonding portion is removed, or when either the upper connection portion 60 or the lower connection portion 62 is cut, these are clogged with the ball of the gaming machine at the maintenance check of the gaming machine in the gaming store or during the business. Can be found when repairing etc.
[0077]
Since the board box 15 is attached to the back side of the gaming machine, the superposition coupling parts 50 to 53 and 54 to 57 can be confirmed from the back side of the gaming machine, and the state of the upper connection part 60 of the superposition coupling parts 50 to 53 and 54 to 57 and Since the state of the lower connecting portion 62 is visible from the upper lid member 26 side, from the almost front side of the mounting portion of the board box 15, that is, from the back side of the gaming machine, as shown in FIG. Both the state of the upper connecting portion 60 and the state of the lower connecting portion 62 can be visually recognized. In the state where the board box 15 is attached, the superposition coupling parts 50 to 53 are on the open / close free end side of the front frame 1 of the gaming machine and the superposition coupling parts 54 to 57 are on the top of the board box 15 as shown in FIG. In addition, since it is not hidden behind the wiring in the connection area 33, it is easy to see the eyes of the staff.
[0078]
Therefore, when the front frame 1 of the gaming machine is opened, this can be found immediately if the normal polymerization bond portion is cut off.
[0079]
In addition, when the upper connecting portion 60 is cut, even if the fixed polymerization bonding portion is not removed, the cutting trace can be seen, so that it can be easily understood that the upper connecting portion 60 is cut.
[0080]
Further, since the lower connecting portion 62 on the lower side of the upper connecting portion 60 can also be visually recognized, only the lower connecting portion 62 is cut without cutting the upper connecting portion 60 of the polymerization bonding portions 52 and 55 as shown in FIGS. When it is done (the polymerization bond portions 53 and 54 are properly cut), it is easy to find that the trace of the cut is visible and the lower lower connection portion 62 is cut. That is, it is possible to cope with a concealing act that attempts to obscure the fact that only the lower connecting portion 62 has been cut and opened.
[0081]
The identification symbols of the superposition bonding portions 50 to 53 and 54 to 57 are displayed on the top plate portion 44 of the upper cover member 26 of the substrate box 15, and the identification symbols are displayed on the second confirmation member 81 attached to the top plate portion 44. Since the corresponding inspection history column is provided, it is possible to easily identify fraud by checking the identification symbol and inspection history, and confirming whether the bonded superimposing bond is correct or unauthorized removal. be able to.
[0082]
Since the polymerization bonding portions 50 to 53 and 54 to 57 are formed at a plurality of locations of the substrate box 15 and the plurality of polymerization bonding portions are sealed, the sealing effect is enhanced and fraud is easily detected.
[0083]
Thus, without removing the board box 15, from the back side of the gaming machine, the superposition coupling parts 50 to 53, 54 to 57 of the board box 15, the state of the upper connection part 60, the lower connection part 62, and the first The contents described in the confirmation member 80 and the second confirmation member 81 can be visually confirmed. Even if there is an illegal act, it can be easily performed at the time of maintenance / inspection of the gaming machine or when the ball jamming of the gaming machine is corrected. Can be discovered early. For this reason, illegal deterrence can be achieved.
[0084]
Therefore, it is possible to prevent fraudulent acts such as excision of the overlapped portion, opening the board box 15, and illegally replacing the ROM 31 of the control circuit board 30, and minimizing the damage to the amusement shop due to such fraudulent acts. Can do.
[0085]
Further, when the board box 15 is attached to or removed from the gaming machine, wiring is not entangled with the superposition coupling parts 50 to 53 and 54 to 57, so that the attachment and removal are easy, and it is also possible by a public organization. When the inspection is performed by removing the board box 15 from the gaming machine at the time of inspection, the removal and attachment work is easy, and the inspection can be performed smoothly.
[0086]
The top lid member is used to cut the overlapped portion or tighten the one-way screw 65 of the overlapped portion by the hinge portion 40 and the locking portion 43 provided on the upper cover member 26 and the base member 25 of the substrate box 15. 26 and the base member 25 do not move, and it becomes easy to cut the overlapped portion and fasten the one-way screw 65.
[0087]
If the upper lid member 26 is closed by the hinge part 40, the locking part 43, and the engaging parts 67, 68 provided in the upper coupling part 61 and the lower coupling part 63 of the superposition coupling parts 50-53, 54-57. In addition, the polymerization bonding portions 50 to 53 and 54 to 57 can be reliably polymerized and can be easily aligned, and the one-way screw 65 can reliably bond and fix the corresponding polymerization bonding portions.
[0088]
At the time of inspection by a public institution, the inspection can be performed without removing the board box 15 from the gaming machine. At this time, if the overlapped bonding portion is fixed and the locking portion 43 is removed, the upper lid member 26 can be easily opened, and the upper lid member 26 can be kept open by the butterfly portion 40 downward. The ROM 31 can be easily removed from the control circuit board 30. Further, the ROM 31 can be easily mounted after the inspection is completed.
[0089]
Therefore, attachment / detachment work of the board box 15 to / from the gaming machine, opening of the board box 15, sealing work, and inspection work can be easily performed, and workability can be improved.
[0090]
Although the one-way screw 65 is used as a fastening member for the overlapping portions 50 to 53 and 54 to 57, a rivet may be used. Anything can be used as long as 15 cannot be opened.
[0091]
Further, the polymerization bonding portion 50 is provided at two locations of the upper lid member 26 of the substrate box 15 and the peripheral walls 38b, 35b, 38c, 35c of the base member 25, that is, at two sides of the plurality of sides as seen from the upper lid member 26 side. ˜53, 54˜57 are formed, but may be formed only on one of them.
[0092]
Moreover, although the example applied to the board | substrate box of the accessory control apparatus was shown in embodiment, if it has the same important parts as ROM which memorize | stored the game program, it can apply, without limiting to this. . Further, the substrate box may accommodate not only one accessory control device but also a ball discharge control device or other control device.
[0093]
FIGS. 15 to 18 show another embodiment, and fitting portions in which the coupling portions are fitted to the upper coupling portion 90 and the lower coupling portion 91 of the overlapping coupling portions 50 to 53 and 54 to 57, respectively. 92 is formed.

It is formed. The walls 94 on both sides of the groove 93 are formed to protrude upward from the upper surface of the lower coupling portion 63.
[0095]
Therefore, in a state where the upper lid member 26 is closed with respect to the base member 25, the upper connecting portion 90 is fitted into the groove 93 of the lower connecting portion 91 as shown in FIG.
[0096]
If it does in this way, when the connection parts 90 and 91 are seen from the upper cover member 26 side, the state of both the connection parts 90 and 91 can be visually recognized, and one side of the upper connection part 90 and the lower connection part 91 by fitting. It becomes difficult to cut off only, and the effect of preventing fraud is increased.
[0097]
The groove 93 of the lower connecting portion 91 may be deepened and the lower portion of the upper connecting portion 90 may be protruded downward from the upper connecting portion 61. Further, the cross-sectional shapes of the upper connecting portion 90 and the lower connecting portion 91 may be curved or inclined.
[0098]
19 to 22 show another embodiment. In the state in which the upper lid member 26 is closed with respect to the base member 25, the upper coupling of the polymerization bonding portions 50 to 53 and 54 to 57 from the upper lid member 26 side. When the portion 95 and the lower connecting portion 96 are viewed, the upper connecting portion 95 and the lower connecting portion 96 are formed so as to be seen in symmetrical positions, respectively, so that the state of the connecting portion 95 and the connecting portion 96 can be visually recognized. In addition, since the connecting portion 95 and the connecting portion 96 can be directly visually recognized, the cutting trace can be easily recognized.
[0099]
As shown in FIGS. 21 and 22, the upper connecting portion 95 is formed eccentrically on the left side with respect to the upper connecting portion 61, and the lower connecting portion 96 is formed eccentrically on the right side with respect to the lower connecting portion 63. That is, they are formed alternately. In this case, there may be a portion overlapping the connecting portions 95 and 96.
[0100]
If it does in this way, the lower connection part 96 can be made small. Moreover, the shape of the upper connection part 95 and the lower connection part 96 is not specifically limited.
[0101]
In each embodiment, the cross-sectional shapes of the upper connecting portion and the lower connecting portion may not be constant.
[0102]
Moreover, although the example applied to the pachinko gaming machine was shown as a gaming machine, it is applicable also to other gaming machines, for example, gaming machines, such as a pachislot and an arrangement ball.

【The invention's effect】
  As described above, according to the first aspect of the present invention, polymerization is performed via the connecting portions that protrude from the upper lid member and the base member, respectively, at the opposing portions of the upper lid member and the base member of the board box that accommodates the control circuit board. By forming multiple polymerization bonds and fixing one of them with a fastening member, the board box cannot be opened.ClosedAsThe cross-sectional outer width of the lower connecting portion protruding from the base member is set to be larger than the cross-sectional outer width of the upper connecting portion protruding from the upper lid member. Therefore, in a state in which the board box is attached to a predetermined position of the gaming machine, it is easy to visually recognize the state of the connecting portion on the base member side, and it is possible to easily grasp whether or not the lower connecting portion is cut.
[0104]
For this reason, the substrate box can be opened and sealed without breaking the polymerization bond portion, and for example, in order to generate a jackpot illegally, the connection portion of the polymerization bond portion that is properly fixed is cut to remove the substrate box. Even if the control circuit board ROM is replaced with an illegal ROM or an illegal act of rewriting the ROM data is performed, this may occur at the maintenance check of the gaming machine in the amusement store or during business. It is easily discovered when correcting ball clogging. In this case, in order to make it difficult to understand that the substrate box has been opened, only the connecting portion on the base member side may be cut without cutting the connecting portion on the upper lid member side of the polymerization bonding portion. Even in the concealing action, the state of the connecting portion on the base member side can be visually recognized and grasped, and therefore fraud due to the cutting of the connecting portion can be easily and quickly discovered. Accordingly, fraud can be prevented and fraud can be prevented.Further, since the connecting portion on the upper lid member side is fitted into the groove formed in the connecting portion on the base member side, it becomes difficult to cut only the connecting portion on one side, and it is possible to further prevent fraud.
[0106]
  First2According to the invention, when the substrate box is closed, the overlapping portion is securely overlapped by the engaging protrusion formed on the upper connecting portion and the engaging protrusion formed on the lower connecting portion. The connecting portion can be easily and accurately fixed, and the upper connecting portion and the lower connecting portion are alternately formed so that they can be visually recognized from the front side in a state where the board box is mounted at a predetermined position of the gaming machine. Unauthorized opening of the substrate box by cutting one of the part and the lower connecting part can be easily found.
