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を介して接続することにより、それぞれに関わる制御が可能となっている。
【０００６】
基板ボックスには、遊技制御に関わる制御回路基板が収容されているので、いたずらや不正行為の対象になりやすく、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。
【０００７】
【発明が解決しようとする課題】
しかしながら、基板ボックスが封印されていたとしても、基板ボックス内の制御回路基板上のコネクタ部に対して各種装置から延出している各種配線を接続する目的で露出状態で設けられている接続領域を利用して、不正行為者はいたずらや不正行為を行う恐れがあった。
【０００８】
例えば、遊技機（本体枠）が閉じている場合に、ピアノ線等の異物を本体枠の隙間から差し込まれて基板のパターン面にいたずらをされたり、コネクタ部を抜かれるいたずらをされる恐れがあり、また本体枠を開けられた状態では、可変表示遊技の始動信号の入力等を外部回路を基板に接続して不正を加える不正行為が行われる心配があった。
【０００９】
また、制御回路基板が露出していることで、島設備や遊技機内にたくさん貯蔵される球等が、例えば遊技機内を循環している球が露出している部分に紛れ込んで接触したり、その他の金属部材が触れてショートする心配もあった。また、遊技盤（ベニヤ）を交換する際等、コネクタ部の抜き差しを容易に行える半面、差し間違えをする可能性もあった。
【００１０】
これらのことを防止するために制御回路基板のすべてを覆うことも考えられるが、遊技機の設置時や遊技盤を交換する際には、制御回路基板のコネクタ部と遊技盤から延びる配線のコネクタ部を接続する必要があるので、その接続を容易にする必要があり、制御回路基板のすべてを覆うことは、作業効率を悪化させる恐れがあった。
【００１２】
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で、配線を接続するために露出状態となっている制御回路基板を保護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。
【００１３】
【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、前記制御回路基板は、前記基板ボックスを遊技機の所定位置に設置した状態において、前記電気的作動装置から延出する配線コード群とコネクタ部を介して電気的に接続可能とし、各種遊技機に対して配線の仕様が共通する共通コード群接続領域と、専用の専用コード群接続領域とからなる配線コード群接続領域を有し、前記基板ボックスは、前記配線コード群接続領域を除いて前記制御基板を表側と裏側とから覆う、天板部と該天板部の四方に形成される４つの周壁とを備えた上蓋部材と、前記制御回路基板より大きい底部と該底部の四方に形成される４つの周壁とを備えたベース部材と、を備え、前記上蓋部材の周壁とベース部材の周壁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列状にそれぞれ所定間隔を開けて複数形成して、このうちのいずれか一つの重合結合部に対し締め方向に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閉止する不正開放防止結合手段を設け、前記上蓋部材は、該上蓋部材の前記配線コード群接続領域側の周壁より延設して、前記上蓋部材及び前記ベース部材とは別体に設けられたカバー部材と共に前記配線コード群接続領域を覆う補助カバー部を備え、前記補助カバー部には、前記上蓋部材を閉じる際に、共通コード群接続領域に設けたコネクタ部に嵌る開口部を形成する。
【００１８】
【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。
【００１９】
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。
【００２０】
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。
【００２１】
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。
【００２２】
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。
【００２３】
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。
【００２４】
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（雄コネクタ）である。
【００２５】
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。
【００２６】
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。
【００２７】
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。
【００２８】
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。
【００２９】
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。
【００３０】
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。天板部４４の周壁３８ｄに沿う部位には、周壁３８ｄの高さを低くして段差が形成される。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。
【００３１】
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。
【００３２】
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。
【００３３】
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側および蝶着部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。
【００３４】
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。
【００３５】
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。
【００３６】
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。
【００３７】
下方連結部６２は上方連結部６０に隠れることのないように、図７のように例えば下方連結部６２の幅が上方連結部６０の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。上方連結部６０、下方連結部６２は、それぞれニッパ等で切断可能に形成される。なお、両方の連結部６０，６２の状態が視認可能であれば、例えば上方連結部６０をクリア部材にして下方連結部６２まで透けて見えるようにする等、他の方法でも良い。
【００３８】
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形成される。
【００３９】
一方、制御回路基板３０の配線コード群の接続領域３３を覆う透明の樹脂からなるカバー部材８０が設けられる。カバー部材８０は、上蓋部材２６およびベース部材２５とは別体に設けられ、ベース部材２５の周壁３５ｄの内面に接すると共に、配線コード群の接続領域３３を囲う周壁３５ａ，３５ｃの部位に重なる大きさに形成される。このカバー部材８０が重なる部位の周壁３５ａ，３５ｃの高さはカバー部材８０の厚さ分、低く形成される。
【００４０】
カバー部材８０には、配線コード群の接続領域３３に設けられたそれぞれの雄コネクタ３２に対応する位置に、それぞれコネクタ３２の形状よりもいくらか大きい開口部８１が形成される。カバー部材８０の両端には、突片８２が設けられ、カバー部材８０の内側の縁部には、小さな孔８３が設けられる。
【００４１】
このカバー部材８０をベース部材２５に着脱可能に取付けるように、カバー部材８０の両端の突片８２に対応して、ベース部材２５の周壁３５ａ，３５ｃには門型の係止片８４が形成される。また、上蓋部材２６の周壁３８ｄの下端には、カバー部材８０の内側の縁部の孔８３に対応して、固定用のボス８５が突設される。
【００４２】
ただし、図２〜図４の配線コード群の接続領域３３の雄コネクタ３２、カバー部材８０の開口部８１は概略的に表してある。
【００４３】
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。
【００４４】
図７のように、上蓋部材２６の天板部４４の表面には、後述する機種名表示票７６、検査履歴書７７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符号が表示される。
【００４５】
この識別符号は、公的機関のＲＯＭ３１等の電子部品の検査時に関わる封印、開放の順位を示しており、印刷あるいは打刻（成型表示を含む）によって、あるいは識別符号を印刷したシールを貼り付けることによって、表示される。なお、天板部４４の内面に印刷、打刻（成型表示を含む）、あるいはシールを貼り付けることによって、表示するようにしても良い。また、重合結合部自体に印刷や打刻（成型表示を含む）をしても良い。
【００４６】
また、カバー部材８０の所定の位置には、機種名（例えば、ソフィア丸）が印刷あるいは打刻（成型表示を含む）によって、あるいは機種名を印刷したシールを貼り付けることによって、表示される。なお、カバー部材８０の機種名は、カバー部材８０の内面に印刷、打刻（成型表示を含む）、あるいはシールを貼り付けることによって、表示するようにしても良い。
【００４７】
なお、図７のように制御回路基板３０の各雄コネクタ３２の近傍には、制御回路基板３０上にコネクタの識別情報（コネクタ番号；ＣＮ１、ＣＮ２、ＣＮ３…）が記してある。
【００４８】
次に、この基板ボックス１５の組立ておよび遊技機への組付けについて説明する。
【００４９】
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。
【００５０】
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。
【００５１】
上蓋部材２６とベース部材２５との蝶着部４０を掛け合わせ、あるいはその蝶着部４０を掛け合わせる前に、図８、図９のようにカバー部材８０をベース部材２５に取付ける。この場合、カバー部材８０をたわませて、両端の突片８２をベース部材２５の周壁３５ａ，３５ｃの係止片８４に嵌めて、取付ける。
【００５２】
この取付状態において、カバー部材８０の各開口部８１に制御回路基板３０の配線コード群の接続領域３３の対応する各雄コネクタ３２が嵌まり、各雄コネクタ３２がカバー部材８０の外部に配線コード群のコネクタ部（雌コネクタ）９０を挿着可能に臨むと共に、各雄コネクタ３２の部分を除いて制御回路基板３０の配線コード群の接続領域３３の全体がカバー部材８０によって覆われる。
【００５３】
続いて、掛け合わせた蝶着部４０を介して上蓋部材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、位置決めされると同時に、上蓋部材２６の周壁３８ｄの下端に突設したボス８５がカバー部材８０の内側の縁部の孔８３に嵌まり、上蓋部材２６の周壁３８ｄの下端のボス８５とベース部材２５の周壁３５ａ，３５ｃの係止片８４とでカバー部材８０が固定される。
【００５４】
また、上蓋部材２６を閉じると、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。
【００５５】
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、識別符号１の重合結合部５０，５４を結合、固着する。
【００５６】
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、注意書き等の各仕様を記載した機種名表示票７６、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ＲＯＭ３１等の電子部品の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を設けた検査履歴書７７を取付ける。
【００５７】
機種名表示票７６は、上蓋部材２６の天板部４４の蝶着部４０側に、検査履歴書７７は天板部４４の重合結合部５４〜５７の識別符号に沿う側に、制御回路基板３０のＲＯＭ３１を上蓋部材２６を通して視認するのに支障のないよう、ＲＯＭ３１を覆う部位を除くよう、天板部４４のほぼ中央にＲＯＭ３１の大きさと略同等以上の面を空けて、貼着により取付ける。
【００５８】
この場合、機種名表示票７６は、樹脂等のプレートに遊技機メーカー名、各仕様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、各仕様を予め天板部４４に印刷あるいは打刻するようにしても良い。
【００５９】
検査履歴書７７は、公的機関の検査に関わる基板ボックス１５の封印、開放つまり重合結合部５０〜５３，５４〜５７の状態を管理するために、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、そ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の識別符号１，２，３，４に対応して、順に第１、第２、第３、第４の表示の印刷等を行っておく。重合結合部５０〜５３，５４〜５７の識別符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、検査時の作業が容易になると共に、識別符号、検査履歴を見て、重合結合部の状態を的確に照合することができる。
【００６０】
この検査履歴書７７は、前記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。
【００６１】
なお、機種名表示票７６、検査履歴書７７は、上蓋部材２６の天板部４４の内面に、つまり機種名表示票７６、検査履歴書７７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、埃等によって機種名表示票７６、検査履歴書７７が汚れたり、表示が見えにくくなるようなことはなく、また機種名表示票７６、検査履歴書７７が剥がれたり、傷付いたりするようなこともない。
【００６２】
そして、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。
【００６３】
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。
【００６４】
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。
【００６５】
この取付後、カバー部材８０の開口部８１より露出している制御回路基板３０の接続領域３３の各雄コネクタ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各配線コード群１７〜２０の各雌コネクタ９０をそれぞれ嵌め込み、接続する。
【００６６】
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。
【００６７】
このように、カバー部材８０によって制御回路基板３０の配線コード群の接続領域３３を覆うため、例えば遊技機の前面枠１の隙間からピアノ線等の異物を差し込まれて、制御回路基板３０のパターン面に傷を付けたりするいたずらをされることが防止される。
【００６８】
また、カバー部材８０は上蓋部材２６を開けないと取り外せず、上蓋部材２６は後述するように封印してある重合結合部を切除しないと開けられない。このため、遊技機の前面枠１を開けられた状態でも、例えば制御回路基板３０に外部回路を接続しての不正は簡単には行えず、外部回路によって可変表示遊技の始動信号の入力等に不正を加えるような不正行為を防止できる。
【００６９】
また、制御回路基板３０にゴミや埃が付着するのが防止される。また、島設備や遊技機内の球等の金属部材が制御回路基板３０に触れることがなく、ショートを確実に防止できる。また、制御回路基板３０の損傷等が防止される。
【００７０】
また、カバー部材８０の各開口部８１より制御回路基板３０の接続領域３３の各雄コネクタ３２が露出しているため、カバー部材８０を取り外すことなく、各雄コネクタ３２に対応する表示制御装置１２、球排出制御装置１３、各種電気機器からの各配線コード群１７〜２０の各雌コネクタ９０を容易に嵌め込み、接続できる。
【００７１】
この場合、カバー部材８０が透明の部材からなるため、図７のように制御回路基板３０に記してあるコネクタの識別情報（コネクタ番号；ＣＮ１、ＣＮ２、ＣＮ３…）を見ながら雄コネクタ３２と雌コネクタ９０との接続を行える。
【００７２】
また、各雌コネクタ９０を容易に外すことができ、遊技機の設置時、遊技盤の交換時および検査時等、良好な作業性を得ることができる。
【００７３】
また、カバー部材８０を上蓋部材２６、ベース部材２５と別体に形成したため、遊技機種によって電気部品、配線量が変わり、制御回路基板３０のコネクタの数や大きさや配置等が変化した場合、これらにしたがってカバー部材８０に設ける開口部８１を変更、即ちカバー部材８０のみを変更すれば良い。このため、遊技機種が異なっても、制御回路基板３０と対応するカバー部材８０のみを変更するだけで、基板ボックス１５を共用でき、コストの低減を図れる。
【００７４】
なお、カバー部材８０を通して制御回路基板３０の接続領域３３の基板パターンを確認でき、その点検を行える。
【００７５】
一方、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、検査を行う。
【００７６】
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、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符号１の重合結合部５０，５４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５０，５４を取り除く。
【００７７】
この重合結合部５０，５４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。この場合、制御回路基板３０の接続領域３３を覆うカバー部材８０を、上蓋部材２６と別体に形成してあるため、接続領域３３の雄コネクタ３２より配線コード群の雌コネクタ９０を外さずに上蓋部材２６を開けることができ、このため作業性が良い。
【００７８】
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。
【００７９】
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が係止すると共に、切除していない識別符号２〜４の重合結合部５１〜５３，５５〜５７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。
【００８０】
この状態にて、識別符号２の重合結合部５１，５５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５１，５５を結合、固着する。この場合、識別符号２〜４の重合結合部５１〜５３，５５〜５７が確実に重合するため、識別符号２の重合結合部５１，５５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。
【００８１】
後は、上蓋部材２６の天板部４４の検査履歴書７７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。
【００８２】
なお、基板ボックス１５を遊技機の裏メカベース盤１０より取り外して、検査を行う場合は、制御回路基板３０の接続領域３３の雄コネクタ３２より配線コード群の雌コネクタ９０を外し、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。基板ボックス１５を外した後は、前述と同様の作業手順にて検査を行う。
【００８３】
このような基板ボックス１５に対して、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。
【００８４】
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、または上方連結部６０あるいは下方連結部６２の一方のみを切断して、重合結合部を取り除かずに、基板ボックス１５を開けたりすることが想定されるが、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に、発見が可能である。
【００８５】
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、また基板ボックス１５の上蓋部材２６の天板部４４に、図７のように重合結合部５０〜５３，５４〜５７の識別符号を表示すると共に、天板部４４に取付けてある検査履歴書７７にその識別符号に対応する検査履歴の欄を設けるため、その識別符号、検査履歴を見て、正規に固着してある重合結合部はどれか、固着してある重合結合部が正しいものかどうか等の照合を簡単に行え、該当する重合結合部、上方連結部６０、下方連結部６２の状態の確認をしやすくなる。
【００８６】
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、すぐに分かり、また固着してある重合結合部が取り除かれていなくとも、その重合結合部の上方連結部６０ならびに下方連結部６２の状態を見て、これらが切断されているかどうかの判断を簡単に行え、不正があるかどうかを容易に速やかに見付けることができる。
【００８７】
また、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、不正行為者にとっては基板ボックス１５を開けにくくなり、封印効果が高まることに加え、不正を発見しやすくなる。特に、遊技店の係員にとっては、重合結合部５０〜５３，５４〜５７の一方を確認すれば良いので、確認ならびに不正の発見が容易になる。
【００８８】
このように、不正行為があった場合、基板ボックス１５を取り外さずに、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のである。このため、不正抑止を図れる。
【００８９】
したがって、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。
【００９０】
なお、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。
【００９１】
図１０〜図１２は第２の実施の形態を示すもので、制御回路基板３０の配線コード群の接続領域を、各種遊技機に対して配線の仕様が共通する共通コード群接続領域１００と、専用の専用コード群接続領域１０１とに画成して、専用コード群接続領域１０１を覆うカバー部材１０２を設けると共に、共通コード群接続領域１００を覆う補助カバー部１０３を上蓋部材２６より延設したものである。
【００９２】
共通コード群接続領域１００には、各種遊技機にそれぞれ共通に使用される遊技機の前面枠１のランプ、スピーカ、打球発射装置等の配線用コネクタ（雄コネクタ）１０４ａ，１０４ｂが設けられ、上蓋部材２６の周壁３８ｄから共通コード群接続領域１００側に延設された補助カバー部１０３に、雄コネクタ１０４ａ，１０４ｂに対応する位置に、それぞれコネクタの形状よりもいくらか大きな開口部１０５ａ，１０５ｂが形成される。補助カバー部１０３の専用コード群接続領域１０１側の端部は内側に折り曲げられ、その中央下部に係止溝１０６が設けられる。
【００９３】
専用コード群接続領域１０１には、遊技機種毎に専用に使用されるあるいは仕様が異なり、配置や数が変化する電気部品の配線用コネクタ（雄コネクタ）１０７ａ〜１０７ｆが設けられ、上蓋部材２６およびベース部材２５とは別体に設けられたカバー部材１０２に、雄コネクタ１０７ａ〜１０７ｆに対応する位置に、それぞれコネクタの形状よりもいくらか大きな開口部１０８ａ〜１０８ｆが形成される。カバー部材１０２の両端には、突片１１０が設けられ、カバー部材１０２の内側の縁部には、小さな孔１１１が設けられる。
【００９４】
ベース部材２５の周壁３５ｃには、カバー部材１０２の突片１１０に対応して、門型の係止片１１２が形成される。また、上蓋部材２６の周壁３８ｄの下端には、カバー部材１０２の内側の縁部の孔１１１に対応して、固定用のボス１１３が突設される。
【００９５】
したがって、基板ボックス１５を組立てる場合、底部に下部保護板２７、制御回路基板３０、上部保護板２８をネジ止めしたベース部材２５と上蓋部材２６との蝶着部４０を掛け合わせ、あるいはその蝶着部４０を掛け合わせる前に、図１１、図１２のようにカバー部材１０２の一端の突片１１０をベース部材２５の周壁３５ｃの係止片１１２に嵌め、カバー部材１０２の開口部１０８ａ〜１０８ｆを対応する雄コネクタ１０７ａ〜１０７ｆに合わせて、配置する。
【００９６】
次に、掛け合わせた蝶着部４０を介して上蓋部材２６を閉じれば、上蓋部材２６より延設した補助カバー部１０３の開口部１０５ａ，１０５ｂが対応する雄コネクタ１０４ａ，１０４ｂに嵌まると共に、上蓋部材２６の周壁３８ｄのボス１１３がカバー部材１０２の縁部の孔１１１に、補助カバー部１０３の係止溝１０６にカバー部材１０２の突片１１０が嵌まり、カバー部材１０２はボス１１３、係止片１１２、係止溝１０６によって固定される。
【００９７】
この状態において、共通コード群接続領域１００、専用コード群接続領域１０１の各雄コネクタ１０４ａ，１０４ｂ、１０７ａ〜１０７ｆが外部に配線コード群のコネクタ部（雌コネクタ）を挿着可能に臨むと共に、各雄コネクタ１０４ａ，１０４ｂ、１０７ａ〜１０７ｆの部分を除いて制御回路基板３０の共通コード群接続領域１００、専用コード群接続領域１０１の全体が補助カバー部１０３、カバー部材１０２によって覆われる。なお、その他の構成は前記第１の実施の形態と同じである。
【００９８】
このようにすれば、遊技機種によって制御回路基板３０のコネクタの数や大きさや配置等が変化しても、機種毎に異なる部分は専用コード群接続領域１０１のカバー部材１０２だけであるので、基板ボックス１５の共用可能な部分が多くなると共に、変更部分が小さくて済み、設計変更が容易であり、コスト削減になる。
【００９９】
なお、雄コネクタ１０４ａ，１０４ｂ、１０７ａ〜１０７ｆの位置にしたがい補助カバー部１０３の延設位置、カバー部材１０２の配置位置を変更して良い。
【０１００】
図１３は第３の別の実施の形態を示すもので、カバー部材１２０の開口部１２１が制御回路基板３０の配線コード群の接続領域１２２に設けたコネクタ部（雄コネクタ）１２３の上面の上方に位置するようにしたものである。
【０１０１】
この場合、前記第１の実施の形態において、ベース部材２５の周壁３５ａ〜３５ｄの高さを高くする。なお、その他の構成は前記第１の実施の形態と同じである。
【０１０２】
ところで、配線コード群の接続領域が外部に露出している場合、コネクタの抜き差しは容易であった半面、コネクタの差し間違いもたびたび起こっていた。例えば、同じ色のコネクタが複数配置されている場合には、ピン数の異なるコネクタに差し込むことがあった。また、コネクタを間違えていなくても、差し込む位置がずれて、ピンにうまく入らないこともあった。
【０１０３】
これに対して、図１３〜図１５のようにカバー部材１２０の開口部１２１をコネクタ部１２３の上面の上方に位置させると、開口部１２１より大きなコネクタ部（雌コネクタ）１２４は挿入できなくなり、一方開口部１２１に比してコネクタ部１２４のサイズがかなり小さい場合は、コネクタ部１２４が違うことが容易に分かる。
【０１０４】
したがって、コネクタ部１２４の接続間違いが少なくなる。また、開口部１２１がガイドとなるため、ピンの位置がずれることがなく、コネクタ部１２４をコネクタ部１２３に接続しやすくなる。
【０１０５】
また、例えば遊技店での保守点検の際や、不正行為者のいたずら等で、配線コードが引っ張られても、開口部１２１が上方にあることで引っ掛かりが生じ、不用意にコネクタ部１２４が抜けにくくなる。また、制御回路基板３０、コネクタ部の破損、損傷を防止できる。
【０１０６】
なお、実施の形態では、コネクタ部として制御回路基板上に設けられるコネクタを雄コネクタ、配線コード群のコネクタを雌コネクタとしたが、互いに接続可能なコネクタであれば、制御回路基板、配線コード群それぞれの組み合わせを変えても良い。また、互いに接続可能なコネクタであれば、実施の形態のものに限定されない。
【０１０７】
なお、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。
【０１０８】
【発明の効果】
以上のように第１の発明によれば、カバー部材と共に補助カバー部によって制御回路基板の配線コード群接続領域を覆うため、制御回路基板へのいたずらおよび不正行為を防止できる。また、制御回路基板にゴミや埃が付着するのを防止できる。また、島設備や遊技機内の球等の金属部材が制御回路基板に触れたり、制御回路基板の損傷等を防止できる。また、補助カバー部の開口部より配線コード群接続領域のコネクタ部が臨むため、各種電気的作動装置の配線コード群のコネクタ部を容易に接続でき、遊技機の設置時、遊技盤の交換時および検査時等、良好な作業性を得ることができる。

In addition, when replacing the game board (veneer), the connector part can be easily inserted and removed, but there is also a possibility of making a mistake.
[0010]
In order to prevent these problems, it is conceivable to cover the entire control circuit board. However, when installing a gaming machine or replacing the game board, the connector part of the control circuit board and the wiring connector extending from the game board Since it is necessary to connect the parts, it is necessary to facilitate the connection, and covering all of the control circuit board may deteriorate the working efficiency.

In this case, the cover member 80 is bent, and the protruding pieces 82 at both ends are fitted to the locking pieces 84 of the peripheral walls 35a and 35c of the base member 25 and attached.
[0052]
In this attached state, each male connector 32 corresponding to the connection region 33 of the wiring cord group of the control circuit board 30 is fitted in each opening 81 of the cover member 80, and each male connector 32 is connected to the outside of the cover member 80. The connector portion (female connector) 90 of the group is faced so as to be insertable, and the entire connection region 33 of the wiring cord group of the control circuit board 30 is covered by the cover member 80 except for the portions of the male connectors 32.
[0053]
Subsequently, the upper lid member 26 is closed via the hinged portions 40 that are crossed. At this time, the protrusion 41 of the locking portion 43 between the upper lid member 26 and the base member 25 is fitted into the locking piece 42, so that the upper lid member 26 is locked and positioned by the base member 25, and at the same time, the upper lid member 26. The boss 85 projecting from the lower end of the peripheral wall 38d is fitted into the hole 83 at the inner edge of the cover member 80, and the boss 85 at the lower end of the peripheral wall 38d of the upper lid member 26 and the peripheral walls 35a, 35c of the base member 25 are locked. The cover member 80 is fixed to the piece 84.
[0054]
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 53 and 54 to 57 are fitted into the engagement receiving portions 68 of the lower coupling portions 63, respectively. While polymerizing.
[0055]
In this state, the one-way screw 65, in which one of the polymerization coupling portions 50 to 53 and one of the polymerization coupling portions 54 to 57 are temporarily fixed to the upper coupling portion 61, is connected to the lower coupling portion 63. Securely tighten, bond and stick. In this case, the superposition | bonding coupling parts 50 and 54 of the identification code 1 are couple | bonded and fixed.
[0056]
After this, on the surface of the substrate box 15, that is, the surface of the top plate portion 44 of the upper lid member 26, each specification such as a game machine manufacturer name, model name, voltage, capacity, precautions, etc. is provided on a transparent seal as shown in FIG. And a board control number including a manufacturer symbol on a predetermined seal or the like (not shown) and a public box inspects an electronic component such as a ROM 31 by a board box.

[0057]
The model name display sheet 76 is on the hinged part 40 side of the top plate part 44 of the upper lid member 26, and the inspection history sheet 77 is on the side along the identification code of the superposition coupling parts 54 to 57 of the top plate part 44. In order to prevent the 30 ROMs 31 from being viewed through the upper lid member 26, a surface approximately equal to or larger than the size of the ROM 31 is provided at approximately the center of the top plate part 44 so as to remove the portion covering the ROM 31, and attached by sticking. .
[0058]
In this case, the model name display tag 76 is obtained by adhering the machine manufacturer name and each specification printed or stamped (including molding display) on a plate of resin or the like to the top plate portion 44 of the upper lid member 26 or the top plate. An attachment part such as a fitting groove may be formed on the plate part 44 and attached. The gaming machine manufacturer name and each specification may be printed or stamped on the top plate portion 44 in advance.
[0059]
The inspection resume 77 is used to manage the state of the sealing and opening of the substrate box 15 related to the inspection of the public institution, that is, the state of the polymerization bonding portions 50 to 53, 54 to 57, the number of inspections, the inspection date, the inspection mark, In the column of the inspection history, the identification codes 1, 2, 3, 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 provided in the inspection number field. Corresponding to the above, printing of the first, second, third, and fourth displays is performed in order. If the inspection history column is made to correspond to the identification codes of the polymerization bonding parts 50 to 53 and 54 to 57, the sealing order of the polymerization bonding parts 50 to 53 and 54 to 57 is determined, and the work at the time of inspection becomes easy. The state of the superposition | bonding coupling | bond part can be collated exactly by seeing an identification code and a test | inspection log | history.
[0060]
This inspection history record 77 is affixed to a plate made of resin or the like with a seal provided with a description column of the inspection history and the like, and an attachment portion such as a fitting groove in which the plate can be attached to and detached from the top plate portion 44 of the upper lid member 26 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.
[0061]
The model name display slip 76 and the inspection history record 77 are on the inner surface of the top plate portion 44 of the upper lid member 26, that is, the surface of the model name display slip 76 and the inspection history record 77 is on the surface (outer surface) of the top plate portion 44. You may make it attach toward. In this case, the model name display slip 76 and the inspection history sheet 77 are not soiled or made difficult to see due to dust or the like, and the model name display slip 76 and the inspection history sheet 77 are peeled off or damaged. There is no such thing.
[0062]
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.
[0063]
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.
[0064]
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.
[0065]
After this attachment, each wiring cord from the display control device 12, the ball discharge control device 13, and various electric devices is connected to each male connector 32 of the connection region 33 of the control circuit board 30 exposed from the opening 81 of the cover member 80. The female connectors 90 of the groups 17 to 20 are fitted and connected.
[0066]
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.
[0067]
Thus, in order to cover the connection region 33 of the wiring cord group of the control circuit board 30 with the cover member 80, for example, a foreign object such as a piano wire is inserted from the gap of the front frame 1 of the gaming machine, and the pattern of the control circuit board 30 It is possible to prevent the surface from being tampered with or scratched.
[0068]
Further, the cover member 80 cannot be removed unless the upper cover member 26 is opened, and the upper cover member 26 cannot be opened unless the polymerized bonded portion sealed as described later is excised. For this reason, even when the front frame 1 of the gaming machine is opened, for example, it is not easy to cheat by connecting an external circuit to the control circuit board 30, and the external circuit can be used to input a start signal for a variable display game. It can prevent fraudulent acts that add fraud.
[0069]
Further, dust and dirt are prevented from adhering to the control circuit board 30. Further, the metal member such as a ball in the island facility or the gaming machine does not touch the control circuit board 30, and the short circuit can be surely prevented. Further, damage to the control circuit board 30 is prevented.
[0070]
Further, since each male connector 32 in the connection region 33 of the control circuit board 30 is exposed from each opening 81 of the cover member 80, the display control device 12 corresponding to each male connector 32 is removed without removing the cover member 80. The female connectors 90 of the wiring cord groups 17 to 20 from the ball discharge control device 13 and various electric devices can be easily fitted and connected.
[0071]
In this case, since the cover member 80 is made of a transparent member, the male connector 32 and the female are viewed while looking at the connector identification information (connector numbers; CN1, CN2, CN3...) Written on the control circuit board 30 as shown in FIG. Connection with the connector 90 can be performed.
[0072]
Also, each female connector 90 can be easily removed, and good workability can be obtained when installing the gaming machine, replacing the gaming board, and inspecting.
[0073]
In addition, since the cover member 80 is formed separately from the upper lid member 26 and the base member 25, when the electrical parts and the wiring amount change depending on the game model, and the number, size, arrangement, etc. of the connector of the control circuit board 30 change, these Accordingly, the opening 81 provided in the cover member 80 may be changed, that is, only the cover member 80 may be changed. For this reason, even if the game model is different, the board box 15 can be shared by changing only the cover member 80 corresponding to the control circuit board 30 and the cost can be reduced.
[0074]
Note that the board pattern of the connection region 33 of the control circuit board 30 can be confirmed through the cover member 80, and the inspection can be performed.
[0075]
On the other hand, when inspecting the ROM 31 of the control circuit board 30 in the board box 15 by a public institution, the board box 15 is removed from the back mechanical base board 10 of the gaming machine or attached to the back mechanical base board 10. I do.
[0076]
When the inspection is performed with the substrate box 15 being attached to the back mechanical base board 10, the superposition coupling portions 50 and 54 of the identification code 1 fixed by the one-way screw 65 among the superposition coupling portions 50 to 53 and 54 to 57. The upper connecting portion 60 and the lower connecting portion 62 are cut with a nipper or the like to remove the overlapping portions 50 and 54.
[0077]
Except for the overlapping portions 50 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. In this case, since the cover member 80 that covers the connection region 33 of the control circuit board 30 is formed separately from the upper lid member 26, the female connector 90 of the wiring cord group is not removed from the male connector 32 of the connection region 33. The upper lid member 26 can be opened, and therefore workability is good.
[0078]
When the upper lid member 26 is opened, the inspection is performed with the ROM 31 of the control circuit board 30 removed.
[0079]
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, and the engagement protrusions of the upper coupling portions 61 of the overlapping coupling portions 51 to 53 and 55 to 57 of the identification codes 2 to 4 that are not excised. The portion 67 fits into the engagement receiving portion 68 of each lower coupling portion 63 and positions.
[0080]
In this state, the one-way screw 65, which is temporarily fixed to the upper coupling portion 61 of the polymerization coupling portion 51, 55 of the identification code 2, is tightened to the lower coupling portion 63, and the polymerization coupling portions 51, 55 are coupled and fixed. . In this case, since the polymerization bonding parts 51 to 53 and 55 to 57 with the identification codes 2 to 4 are surely polymerized, the bonding and fixing of the polymerization bonding parts 51 and 55 with the identification code 2 becomes easy and in an incomplete state. There is no worry of tightening the one-way screw 65.
[0081]
After that, if the person in charge of the inspection fills in the first description column of the number of inspections in the inspection history record 77 of the top plate portion 44 of the top cover member 26, the inspection date is completed, and the inspection mark is completed. .
[0082]
When the board box 15 is removed from the back mechanical base board 10 of the gaming machine and the inspection is performed, the female connector 90 of the wiring cord group is removed from the male connector 32 of the connection area 33 of the control circuit board 30, and the base member 25 When the one-touch type stopper 73 is pulled, it can be removed. After removing the substrate box 15, the inspection is performed in the same operation procedure as described above.
[0083]
For such a board box 15, the board box 15 is opened illegally, the ROM 31 of the control circuit board 30 is replaced with an illegal ROM, or the data in the ROM 31 is rewritten to frequently generate jackpots. There is.
[0084]
In this fraudulent act, the upper coupling portion 60 and the lower coupling portion 62 of the polymerization bonding portion that is properly fixed are cut and the polymerization coupling portion is removed, or the upper coupling portion 60 or the lower coupling portion 62 is removed. It is envisaged that only one side is cut and the substrate box 15 is opened without removing the overlapped portion, but this may be caused by a jamming of a gaming machine during a maintenance check of the gaming machine at a gaming store or during business. It can be discovered when repairing.
[0085]
Since the board box 15 is attached to the back side of the gaming machine, the superposition bonding parts 50 to 53, 54 to 57 can be confirmed from the back side of the gaming machine, and the top plate part 44 of the upper cover member 26 of the board box 15 is as shown in FIG. In addition, the identification codes of the superposition bonding parts 50 to 53 and 54 to 57 are displayed, and an inspection history column 77 corresponding to the identification code is provided in the inspection history record 77 attached to the top plate part 44. By checking the inspection history, it is possible to easily check which polymerization bond part is properly fixed, whether the fixed polymerization bond part is correct, the corresponding polymerization bond part, upper connection part 60, It becomes easy to confirm the state of the lower connecting portion 62.
[0086]
Therefore, when the front frame 1 of the gaming machine is opened, it can be easily understood if the normal polymerization bond portion is cut out, and even if the fixed polymerization bond portion is not removed, the upper connection of the polymerization bond portion By looking at the state of the part 60 and the lower connecting part 62, it is possible to easily determine whether or not they are cut, and it is possible to easily and quickly find out whether there is any injustice.
[0087]
Moreover, since the superposition | polymerization coupling | bond part 50-53, 54-57 is formed in the several location of the board | substrate box 15, and a several superposition | polymerization coupling | bond part is sealed, it becomes difficult for a fraudulent person to open the board | substrate box 15, and a sealing effect is carried out. In addition to the increase, fraud is easy to detect. In particular, since it is only necessary to confirm one of the polymerization bond portions 50 to 53 and 54 to 57 for a clerk at a game shop, confirmation and fraud detection are facilitated.
[0088]
In this way, if there is an illegal act, it can be detected easily and early without removing the board box 15 at the time of maintenance / inspection of the gaming machine or when the ball jam of the gaming machine is corrected during the business. . For this reason, illegal deterrence can be achieved.
[0089]
Therefore, an illegal act such as opening the board box 15 and illegally exchanging the ROM 31 of the control circuit board 30 can be prevented, and damage to the amusement shop due to such an illegal act can be minimized.
[0090]
In the embodiment, the example applied to the board box of the accessory control device has been described. However, the embodiment can be applied to any device having the same important parts as the ROM storing the game program. . Further, the substrate box may accommodate not only one accessory control device but also a ball discharge control device or other control device.
[0091]
10 to 12 show a second embodiment. The connection area of the wiring code group of the control circuit board 30 includes a common code group connection area 100 having common wiring specifications for various gaming machines, and FIGS. A cover member 102 that covers the dedicated code group connection area 101 is provided to define a dedicated dedicated code group connection area 101, and an auxiliary cover portion 103 that covers the common code group connection area 100 extends from the upper lid member 26. Is.
[0092]
The common cord group connection area 100 is provided with wiring connectors (male connectors) 104a and 104b for lamps, speakers, ball hitting devices, etc. of the front frame 1 of the gaming machine that are commonly used for various gaming machines. Openings 105a and 105b that are somewhat larger than the shape of the connectors are formed in the auxiliary cover 103 extending from the peripheral wall 38d of the member 26 to the common cord group connection region 100 side at positions corresponding to the male connectors 104a and 104b. Is done. The end portion of the auxiliary cover portion 103 on the dedicated cord group connection area 101 side is bent inward, and a locking groove 106 is provided at the lower center portion thereof.
[0093]
The dedicated cord group connection area 101 is provided with wiring connectors (male connectors) 107a to 107f of electrical components that are used exclusively for each game model or have different specifications and change in arrangement and number. In the cover member 102 provided separately from the base member 25, openings 108a to 108f somewhat larger than the shape of the connectors are formed at positions corresponding to the male connectors 107a to 107f, respectively. Protruding pieces 110 are provided at both ends of the cover member 102, and small holes 111 are provided at the inner edge of the cover member 102.
[0094]
A gate-shaped locking piece 112 is formed on the peripheral wall 35 c of the base member 25 corresponding to the protruding piece 110 of the cover member 102. A fixing boss 113 projects from the lower end of the peripheral wall 38 d of the upper lid member 26 so as to correspond to the hole 111 at the inner edge of the cover member 102.
[0095]
Therefore, when assembling the board box 15, the base member 25 and the upper lid member 26, which have the lower protective plate 27, the control circuit board 30, and the upper protective plate 28 screwed to each other, are joined to each other, or the butterfly attachment thereof. Before the portions 40 are engaged, the protruding piece 110 at one end of the cover member 102 is fitted into the locking piece 112 of the peripheral wall 35c of the base member 25 as shown in FIGS. 11 and 12, and the openings 108a to 108f of the cover member 102 are fitted. It arrange | positions according to corresponding male connector 107a-107f.
[0096]
Next, if the upper lid member 26 is closed via the crossed hinge part 40, the openings 105a and 105b of the auxiliary cover part 103 extending from the upper lid member 26 are fitted into the corresponding male connectors 104a and 104b. The boss 113 of the peripheral wall 38d of the upper lid member 26 is fitted into the hole 111 at the edge of the cover member 102, and the protruding piece 110 of the cover member 102 is fitted into the locking groove 106 of the auxiliary cover portion 103. It is fixed by the stop piece 112 and the locking groove 106.
[0097]
In this state, the male connectors 104a, 104b, 107a to 107f of the common cord group connection region 100 and the dedicated cord group connection region 101 face the outside so that the connector portion (female connector) of the wiring cord group can be inserted to the outside. Except for the male connectors 104a, 104b and 107a to 107f, the entire common code group connection area 100 and the dedicated code group connection area 101 of the control circuit board 30 are covered by the auxiliary cover portion 103 and the cover member 102. Other configurations are the same as those of the first embodiment.
[0098]
In this way, even if the number, size, arrangement, etc. of the connectors of the control circuit board 30 change depending on the game model, the only part that differs for each model is the cover member 102 of the dedicated cord group connection area 101. The number of sharable parts of the box 15 is increased, and the changed part is small, so that the design can be easily changed and the cost can be reduced.
[0099]
The extension position of the auxiliary cover part 103 and the arrangement position of the cover member 102 may be changed according to the positions of the male connectors 104a, 104b, 107a to 107f.
[0100]
FIG. 13 shows a third alternative embodiment, in which the opening 121 of the cover member 120 is located above the upper surface of the connector portion (male connector) 123 provided in the connection region 122 of the wiring cord group of the control circuit board 30. It is intended to be located at.
[0101]
In this case, in the said 1st Embodiment, the height of the surrounding walls 35a-35d of the base member 25 is made high. Other configurations are the same as those of the first embodiment.
[0102]
By the way, when the connection area of the wiring cord group is exposed to the outside, it is easy to insert and remove the connector. On the other hand, mistakes in inserting the connector often occur. For example, when a plurality of connectors of the same color are arranged, they may be inserted into connectors having different numbers of pins. Even if the connector is not mistaken, the insertion position may be shifted and the pin may not be inserted properly.
[0103]
On the other hand, when the opening 121 of the cover member 120 is positioned above the upper surface of the connector 123 as shown in FIGS. 13 to 15, the connector part (female connector) 124 larger than the opening 121 cannot be inserted. On the other hand, when the size of the connector part 124 is considerably smaller than the opening part 121, it can be easily understood that the connector part 124 is different.
[0104]
Therefore, the connection mistake of the connector part 124 decreases. Further, since the opening 121 serves as a guide, the position of the pin is not shifted, and the connector 124 can be easily connected to the connector 123.
[0105]
In addition, even when the wiring cord is pulled due to maintenance inspection at a game store or mischief of a fraudulent person, for example, the opening 121 is located upward, and the connector 124 is inadvertently pulled out. It becomes difficult. Further, breakage and damage of the control circuit board 30 and the connector part can be prevented.
[0106]
In the embodiment, the connector provided on the control circuit board as the connector portion is a male connector and the connector of the wiring cord group is a female connector. However, if the connectors are connectable to each other, the control circuit board and the wiring cord group are used. You may change each combination. Further, the connector is not limited to that of the embodiment as long as the connectors are connectable to each other.
[0107]
In addition, 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.
[0108]
【The invention's effect】
As described above, according to the first invention, With cover member Since the auxiliary cover portion covers the wiring cord group connection area of the control circuit board, tampering with the control circuit board and illegal acts can be prevented. Further, it is possible to prevent dust and dirt from adhering to the control circuit board.
