【０００１】
【発明の属する技術分野】
この発明は、機内の遊技盤で展開されるパチンコゲームの制御に関係する制御基板を機裏側に有するパチンコ遊技機に関するものである。
【０００２】
【従来の技術】
パチンコ機やアレンジボール機に代表されるこの種の遊技機では、遊技操作に基づいて開始される１球毎の球送り発射作動により、上球皿から発射位置に送込まれた遊技球を遊技盤内に打出して所要のパチンコゲームを行ない得る。そしてゲーム中に発生及び成立される様々な入賞条件時や特別遊技状態時等において、機裏側の機構セット盤に着脱可能に装着された制御基板（一般的な代表例として遊技用主制御基板）からの制御指令信号に基づき、例えば図柄可変表示装置や電動式入賞装置等の電気的な遊技部品が夫々の可動条件に従って作動制御されるようになっている。
【０００３】
このような従来の遊技機にあって、前記制御基板は、互いに分離可能なトレー部材とカバー部材からなる合成樹脂製の保護ケース内に、パチンコゲームの制御に関係する回路基板を収容したケース単位のユニット構成とされ、他の遊技機構成要素とは区分して単一で取扱い得るようにされている。そして機構セット盤への装着に際しては、一般例として同セット盤の所定部位に形成された係合部に対して、前記保護ケースにおけるトレー部材又はカバー部材に付設された固定用止め具を係合することにより固定化保持を図っていた。なお、このように装着された制御基板に関しては、その制御基板に対して行われた不正な改変行為を官憲の検査・点検メンテナンス時等に発見できるようにするため、保護ケースを構成するトレー部材とカバー部材の接合部に対し不正に保護ケースが開放された場合の痕跡を残し得るように封印証紙を貼着したり、不正に操作できない止め具（ビス）で結合するようにしていた。
【０００４】
【発明が解決しようとする課題】
しかしながら、前述したような固定用止め具にあっては、不正遊技者により遊技機の搭載枠ともされる前枠が外枠に対するセット状態から回動開放されて機裏側が露呈されたもとで、簡単に前記係合部に対する係合状態を解除可能とされ、このような不正遊技者にとっては比較的容易に遊技機（機構セット盤）から前記制御基板を取外しできるものとなっていた。そして、取外された制御基板については、特殊な薬品等を使用して前記封印証紙が簡単に剥がされたり、専用治具にてトレー部材とカバー部材が分離開放されたもとで、回路基板上の純正電子デバイス（例えばＣＰＵ，ＲＯＭ，ＲＡＭ等）が、遊技データや入賞確率データ等を不正に改ざんされた不正電子デバイスに取換えられるという事態が生じていた。ちなみに、斯かる不正は、深夜の遊技ホール内，外で行われることが多い。
【０００５】
本発明は前述した課題を好適に解決するべくなされたものであって、機裏側の機構セット盤に着脱可能にセットされる制御基板の不正脱着を阻止し得るようにしたパチンコ遊技機を提供することを目的とするものである。
【０００６】
【課題を解決するための手段】
上記目的を達成するため、本願請求項１の発明は、パチンコゲームの制御に関係する制御基板を機裏側の機構セット盤に備えたパチンコ遊技機にあって、前記機構セット盤には、遊技盤の裏側の主要部位に合わせたサイズに形成した窓口の下部に賞球払出しを制御する払出し制御基板を着脱自在に収容セットし得る収容室が後向き開口状に形成され、前記収容室の開口面域を覆蓋し得る開閉支板を開閉連結支持手段により開閉可能に連結支持し、前記開閉支板の外側には、保護ケースに収容してケース単位で構成されたゲーム内容を制御する主制御基板を着脱可能に組付けセットするとともに、前記保護ケースに収容した前記主制御基板を前記開閉支板の内側で係合及び解除が可能な係合手段を利用して固定化保持し、前記収容室には施錠用板が施錠用孔の形成された先端部を前記収容室から外方へ突出するように固定されているとともに、前記主制御基板の保護ケースには前記施錠用板を挿通可能な長孔が形成されており、前記係合手段は、前記開閉支板の内側において前記開閉支板に形成された貫通孔と対応する位置に配設された係合口部と、前記保護ケースの裏面側において前記開閉支板の貫通孔及び前記係合口部と対応する位置に突出形成された弾性変形可能な係合支持部材とからなり、前記主制御基板を前記開閉支板に組付けセットする場合には、前記収容室を露呈する開放位置とした前記開閉支板の貫通孔に前記係合支持部材を通過させて前記係合口部に嵌挿結合し、その後に前記開閉支板を前記開放位置から前記収容室を覆蓋する閉鎖位置に回動し、前記閉鎖位置において前記保護ケースの長孔を通過して外部に突出した前記施錠用板の施錠用孔に錠を挿通し施錠することにより前記開閉支板を開放不能な状態とし、前記主制御基板を前記開閉支板から取外す場合には、前記錠を解錠した後、前記開閉支板を前記閉鎖位置から前記開放位置に回動し、前記開放位置において前記係合口部に係合している前記係合支持部材を弾性変形させて係合状態を解除し、前記貫通孔から抜き出すように構成したことを特徴とする。
【０００７】
従って、本願請求項１の発明においては、機裏側の機構セット盤に対し開閉支板を開放状態にしたもとで同開閉支板の外側に主制御基板を組付けセットし、その後、そのセット状態において開閉支板の内側から係合手段を利用して主制御基板を開閉支板に固定化保持する。そして、この主制御基板が固定化保持された状態の開閉支板を払出し制御基板の収容室を覆蓋するように機構セット盤に対し閉鎖した後、その閉鎖状態において錠にて開放不能に施錠する。すると、主制御基板を開閉支板に固定化保持している係合手段は、機裏側の機構セット盤が不正遊技者などにより露呈させられたもとでも、前記錠を解錠して開閉支板を開放状態としない限り係合解除が不能とされる。
【０００８】
また本願請求項２の発明は、前記請求項１の発明において、前記開閉連結支持手段は、前記開閉支板の一方の側縁に沿うように前記機構セット盤に装着セットされた支持板の上下方向へ所定の間隔をおいて形成した複数の軸受け部と、前記開閉支板の一方の側縁に形成した複数の軸受け部と、各軸受け部に圧入される支ピンとからなり、前記収容室には係合孔を開口形成した弾性変形可能な係合片が形成されているとともに、前記開閉支板の他方の側縁には前記閉鎖位置において前記収容室内に差し込まれ、かつその差込状態において前記収容室側の前記係合片の係合孔に嵌合係止可能な係合爪を突設した差込片が形成されており、前記開閉支板は、前記支持板の軸受け部の間に前記開閉支板の軸受け部を嵌め込み、その嵌め込み状態において各軸受け部へ支ピンが圧入されることにより、前記収容室を閉鎖する閉鎖位置と前記収容室を露呈する開放位置との間で開閉可能に連結支持されるとともに、前記開放位置から前記閉鎖位置に回動されると、前記差込片が前記係合片に摺動当接して前記係合片を横向き外方へ弾性変形させ、前記閉鎖位置に至った時に前記差込片の係合爪が前記係合片の係合孔に嵌合係止されることにより前記閉鎖位置に係止保持され、前記差込片の先端部は横向き内方へ折曲げられ、前記開閉支板を前記閉鎖位置へ回動した際における前記収容室内への前記差込片の差込動作をスムーズにならしめる形態とされ、前記係合片の先端部は横向き外方へ斜状に折曲げられた係合解除用の摘み部とされていることを特徴とする。
従って、本願請求項２の発明においては、前記請求項１の発明の作用に加えて、開閉支板を閉鎖位置から開放位置に回動開放する際には、係合解除用の摘み部を摘んで係合片を横向き外方へ弾性変形させることにより当該係合片の係合孔に対する開閉支板側の係合爪の嵌合係止状態が解除されるので、開閉支板はその摘み部を把持して簡単に開放位置側へ回動開放し得る。また反対に、開放位置にある開閉支板を閉鎖位置に閉鎖セットする際には、開閉支板の閉じ動作に伴い開閉支板の差込片が係合片に摺動当接して当該係合片を横向き外方へ弾性変形させるので、係合孔と係合爪とを自動的に嵌合係止させて開閉支板を簡単に閉鎖セット状態にし得る。
【０００９】
また本願請求項３の発明は、前記請求項２の発明において、前記主制御基板を収容した前記保護ケースは、前記保護ケースに一体形成された突片の軸孔を、前記開閉支板の外側に取付固定された支持片の上向き支軸に挿入することにより、前記開閉支板に対して回動可能な状態で支持され、前記開閉支板の前記軸受け部と前記支持片は、前記保護ケースの一方の側縁に沿って前記軸受け部が配置されるとともに、他方の側縁に沿って前記支持片が配置され、前記開閉支板の回動方向に対して前記保護ケースの回動方向が逆方向に構成されていることを特徴とする。従って、本願請求項３の発明においては、前記請求項２の発明の作用に加えて、主制御基板の保護ケースは開閉支板の外面上に支軸を支点として回動可能に支持された構成であるため、保護ケース内に収容された主制御基板の裏面側（回路パターン等がある）を点検するときには、いちいち保護ケースを開閉支板から持ち上げなくても前記支軸を支点として回動させるだけで簡単にその点検作業を行い得る。
また本願請求項４の発明は、前記請求項２又は請求項３に記載の発明において、前記機構セット盤には、前記支持板の装着領域に隣接して遊技機の球貸しシステムに利用されるカードユニットと前記払出し制御基板とを電気的に接続するインターフェースボードの設置領域が形成されており、前記支持板の複数の軸受け部と前記開閉支板の複数の軸受け部は、上下方向に二分されるように上下方向の途中において前記所定の間隔よりも広い間隔をおいて配置されており、２本の支ピンにより二分された軸受け部の単位でそれぞれに支ピンが圧入されることを特徴とする。従って、本願請求項４の発明においては、前記請求項２又は請求項３の発明の作用に加えて、支ピンが上下２つの分かれることにより、機構セット盤に取り付けられるインターフェースボードの取り外しが容易に行い得る。
【００１０】
【発明の実施の形態】
以下、本発明に係るパチンコ遊技機について、好適な実施形態を挙げて添付図面を参照しながら詳細に説明する。なお本実施形態では、遊技球を１個ずつ遊技盤内に打出して遊技球の入賞ゲーム（アウト球とセーフ球とに区分）を展開し、入賞成立（セーフ球の発生）に伴い機裏側の貯留球を球皿側へ排出供給するようにしたパチンコ機の場合を主に例示する。また、以下の説明において「右」又は「左」は、特にことわらない限り、機裏側から見た場合の「右」又は「左」を示すものとする。
【００１１】
本実施形態のパチンコ機は、その基本的構成の概要として、図１及び図２に略示するように、機体の外郭をなす外枠１の開口前面側に、各種の遊技用構成部材をセットする縦長方形の前枠２が開閉及び着脱可能に組付けられており、この前枠２の前面側に機内部の遊技盤３を透視保護するための窓枠４と上球皿５とが共に横開き形態で開閉可能に組付け整合されると共に、前枠２の下部には下球皿６及び打球発射装置７等が装着されている。なお、外枠１の一側縁には球貸しシステムに利用されるカードユニット８が装備されている。一方、前記前枠２の裏側には各種の球経路及び処理部等を備えた機構セット盤９が着脱可能にセットされており、この機構セット盤９では図２のように前記遊技盤３裏側の主要部位に合わせたサイズに形成した窓口（図示しない）に保護カバー１０が開閉可能にセットされ、また、窓口（図示しない）や保護カバー１０の周囲には、球タンク１１が前記カバー１０の上方に位置して設けられると共に、同タンク１１から整流樋１２を介して貯留球が流下供給される区分供給経路部１３が前記カバー１０の右方領域に上下方向へ延設されている。そして、この区分供給経路部１３の下流端には球払出し装置１４が着脱可能にビス等で取着セットされ、この球払出し装置１４から賞球又は貸し球として払出された貯留球が排出経路（図示しない）を介して前記上球皿５へ供給されるようになっている。
【００１２】
さらに、前記保護カバー１０の下方、即ち、機構セット盤９の下部外側には、後述する開閉支板１５が横開き形態で開閉可能に支持され、同開閉支板１５の外側にゲーム内容を制御する主制御基板１６と、ランプ類の電飾表示部１７の点灯や点滅状態を制御する電飾制御基板１８が配置されている。また、前記開閉支板１５の内側（前側）にはセーフ球検出処理と貯留球排出処理（賞球払出しと貸し球払出し）を制御する払出し制御基板（図２において破線で示す）１９が配置され、開閉支板１５よりも下方位置には前記打球発射装置７の作動状態を制御する発射制御基板２０と、スピーカから発せられる効果音を制御する音声制御基板２１が配置されている。なお、図２中の符号、２２は電源部（ＡＣ２４Ｖ）に接続されると共に賞球情報信号及び球貸し情報信号を図示しない外部コンピュータ等へ出力する外部接続端子板であり、２３は球払出し装置１４と払出し制御基板１９とを電気的に中継接続する中継基板、２４は前記カードユニット８と払出し制御基板１９とを電気的に接続するインターフェースボードである。
【００１３】
このような本実施形態のパチンコ機にあって、前記機構セット盤９の下部には図５に示すように前記払出し制御基板１９を収容セットし得る収容室２５が外向き（後向き）開口状に形成され、同収容室２５内の下部左右に基板載置片２６が前後方向へ延びるように突設されている。また、前記収容室２５内の左側壁面近傍には金属板から形成された掛け止め部材２７が取付固定され、同掛け止め部材２７の右側縁ほぼ中央に先端部２８ａが鉤状をなす基板押え片２８が前後方向へ延びるように外向きに突設されている。さらに、前記掛け止め部材２７の左側縁には係合孔２９を開口形成した上下一対の係合片３０が左右方向へ弾性変形し得るように外方から切欠形成され、各係合片３０の先端部は横向き外方へ斜状に折曲げられた係合解除用の摘み部３１になっている。また、前記掛け止め部材２７の下側縁からは先端部が下向き外方へ斜状に折曲げられた載置ガイド片３２が前後方向へ延びるように外向きに突設されている。ちなみに前記基板押え片２８と係合片３０及び載置ガイド片３２等を有する掛け止め部材２７は一枚の金属板で折曲げ加工されている。
【００１４】
また図５に示すように、前記収容室２５内の右方寄りには、前記基板押え片２８の突設位置から前記払出し制御基板１９の左右方向長さと略等しい間隔をおいた位置に、左右方向へ弾性変形可能なフック３３が前後方向へ延びるように突設されている。従って、収容室２５内に収容された払出し制御基板１９は、前記両基板載置片２６により下方から支持された状態において、その一端（図９では左端）を基板押え片２８の先端部２８ａにより前後方向において掛止め保持されるとともに、その他端（図９では右端）を前記フック３３の弾性力により圧接保持されるようになっている。なお、図５に示すように前記収容室２５内の上部略中央には前記払出し制御基板１９を収容室２５内に収容セットした状態において当該払出し制御基板１９の上端面よりも上方となる位置に複数のボス部３４が横方向へ所定間隔をおいて並設され、このボス部３４に対して施錠用板３５が施錠用孔３６の形成された先端部を収容室２５から大きく外方へ突出するようにしてネジ３７により締着固定されている。
【００１５】
また、前記機構セット盤９の下部外側において前記収容室２５の凹設領域よりも右側方の領域は前記中継基板２３等の設置領域３８とされ、同領域３８のほぼ中央よりも右側部分には中継基板２３を嵌め込み支持するためのボックス３９とインターフェースボード２４を掛け止め保持するための係止爪４０が形成されている。一方、前記設置領域３８のほぼ中央よりも左側部分には複数のリブ４１が縦横へ格子状をなすように形成され（図３，図５参照）、各リブ４１が交差する端面にはネジ穴４２が形成されている。そして、前記設置領域３８の左半分に対応する形状の被覆用の支持板４３が前記リブ４１を覆うように配置されると共に、同支持板４３の複数箇所に前記各ネジ穴４２と対応するように形成された各ネジ孔４４にネジ４５が挿着されて、前記設置領域３８の左半分には支持板４３が装着セットされている。
【００１６】
前記支持板４３は蝶番式支持具の一部として、ほぼ縦長方形状をなす金属板より形成されて、その右側縁には複数（本実施形態では５つ）のカール状の軸受け部４６が上下方向へそれぞれ所定の間隔をおいて曲げ形成されている。そして、この支持板４３の各軸受け部４６の間に前記開閉支板１５の右側縁に曲げ形成された蝶番式の支持具としての複数（本実施形態では３つ）のカール状の軸受け部４７が嵌まり込み、その嵌め込み状態において各軸受け部４６，４７へ丸棒状をなす支ピン４８が着脱不能に適宜圧入されることにより、開閉支板１５は横開き形態で前記収容室２５を覆う閉鎖位置と同収容室２５を露呈させる開放位置との間で開閉可能に支持されている。そして、本実施形態では、前記各軸受け部４６，４７と支ピン４８により開閉連結支持手段４９が構成されている。
【００１７】
一方、図５，１０に示すように前記開閉支板１５の左側縁には前記収容室２５を覆う状態となる閉鎖位置において収容室２５内に差し込まれる差込片５０が内向きに折曲げ形成され、同差込片５０にはその差込状態において収容室２５側の前記係合片３０の係合孔２９に嵌合係止可能な係合爪５１が突設されている。また、差込片５０の先端部は横向き内方へ折曲げられ、開閉支板１５を閉鎖位置へ回動した際における収容室２５内への差込片５０の差込動作をスムーズならしめる形態とされ、また差込片５０の基端部には開閉支板１５の開閉操作を容易ならしめる摘み部５２が形成されている。そして、本実施形態では、前記係合片３０の係合孔２９と前記差込片５０の係合爪５１により係合部が構成されている。
【００１８】
また、図５，６に示すように前記開閉支板１５の右側部には上下一対の貫通孔５３が形成され、この両貫通孔５３と対応する上下一対の係合口部５４を有する合成樹脂製のロック用の係合支片５５が前記貫通孔５３と係合口部５４を一致させるようにして開閉支板１５の内側面にネジ５６により締付け固定されている。そして、前記開閉支板１５の上下各縁には、前記貫通孔５３が形成された位置と前記差込片５０が折曲げ形成された左側縁との間に亘って補強用リブ５７がそれぞれ内方に向けて折曲げ形成され、開閉支板１５が閉鎖位置とされたときには、上側の補強用リブ５７が前記施錠用板３５の下側直近に差し込まれると共に、下側の補強用リブ５７が収容室２５側の前記載置ガイド片３２の上面に摺動案内されて差し込まれるようになっている。
【００１９】
ここで前記開閉支板１５の素材構成について説明すると、この開閉支板１５は前記収容室２５の開口面域（外側）を覆蓋し得る横長方形状に形成された金属板からなり、本実施形態のものにあっては鉄板が使用されている。即ち、パチンコ機においてゲーム内容等を制御する制御基板は一般にその保護ケースが合成樹脂製の成形部材で構成されているため、保護ケース内に収容した回路基板については電磁波遮断対策等を図る必要がある。そこで、本実施形態では、前記主制御基板１６と電飾制御基板１８が装着セットされる開閉支板１５の素材に導電性を有する金属板の一種である鉄板を採用することとしたのである。
【００２０】
このような開閉支板１５の外面における左端寄り領域には、図５に示すように前記電飾制御基板１８にほぼ対応する形状の鉄板から形成された支持板５８が取付固定されており、同支持板５８の両側縁には上下方向に沿う係合溝５９ａを備えた係止爪５９が上下各位置に形成されると共に、その支持板５８の上縁には先端部が鉤状をなす押えフック６０が切欠形成されている。そして、前記各係止爪５９の係合溝５９ａに電飾制御基板１８の両側縁から突設された各係合片６１を上方から挿入すると共に、前記押えフック６０により電飾制御基板１８の上縁を押えることにより、電飾制御基板１８は開閉支板１５の外側に前記支持板５８を介して着脱可能になっている。また、前記支持板５８の右側縁に接するようにして開閉支板１５の外面には上下一対の上向き支軸６２を突設した縦長の支持片６３が取付固定されている。そして、この支持片６３の支軸６２に対して前記主制御基板１６を回動可能に支持し得るようになっている。
【００２１】
さて、本実施形態における主制御基板１６は図１２に例示するように、前記遊技盤３側における各種電気的部品・手段に係る入出力制御等を図る電子デバイス（例として、ＣＰＵ，ＲＯＭ，ＲＡＭ等）６４を接続部６５を介して着脱可能に接続セットする回路基板６６を、図８に例示するように、トレー部材６７と同トレー部材６７を覆蓋するカバー部材６８とが着脱可能に接合された保護ケース６９内に収容してユニット化されたケース単位で取扱い得るようになっている。ところで、パチンコ機に使用される制御基板（例えば、主制御基板１６）にあっては、適正な制御内容（ソフトプログラム内容）で正常に使用することを前提とした不正改造・変更防止対策のため、かかる制御基板を収容するケース体としての保護ケースについては透明樹脂成形することにより保護ケース内に収容された回路基板表面側の電子部品（例えば、電子デバイス６４）や回路基板裏面側の回路パターン等を外部から容易に透視可能とすることが義務付けられている。そのため、本実施形態においても前記回路基板６５の脱着交換や電子デバイス６４の不正改造交換等を容易に発見し得るように、前記保護ケース６９を構成するトレー部材６７及びカバー部材６８については両者６７，６８共に透明な合成樹脂で成形されている。
【００２２】
また、このような主制御基板１６では、前記回路基板６６の不正脱着等に係る不正行為の防止策として、前記保護ケース６９の不正開放を阻止すると共にその不正開放の履歴を残し得るように複数の不正開放防止手段７０を装備している。この不正開放防止手段７０は、図２，図３，図１１等に例示するように、保護ケース６９の下端縁左右両側にそれぞれ４つずつ設けられたものであって、具体的な図示は省略するが、各不正開放防止手段７０はトレー部材６７の下端縁から下方に向け一体成形された下部半体とカバー部材６８の下端縁から下方に向け一体成形された上部半体からなる結合ボス部７１を有している。そして、トレー部材６７にカバー部材６８を覆蓋セットする際に前記上下両半体を整合当接させ、その整合当接状態にある前記結合ボス部７１に締付け専用のビス７２をねじ込むことにより前記トレー部材６７とカバー部材６８を一般工具を使用しても分離不能な状態に接合セットできるようになっている。これにより、前記保護ケース６９を開放して回路基板６６を露出させるには、戻し（逆回し）不能とされた前記ビス７２で連結された結合ボス部７１をトレー部材６７及びカバー部材６８から切断しない限り、トレー部材６７とカバー部材６８を分離開放できないことになり、もしも前記結合ボス部７１を切断することによる不正開放が行われた場合には、その切断の痕跡が明確に残るため不正開放の有無が容易に視認されるものである。なお、本実施形態ではこのような結合ボス部７１が８つ形成されているので、合計７回までの不正開放の痕跡を把握し得る。
【００２３】
一方、前記主制御基板１６の保護ケース６９には、そのトレー部材６７の裏面側に図６，７，９，１０に例示するようなほぼ筒状をなすロック用のフック７３が前記開閉支板１５の貫通孔５３及び開閉支板１５の内側に配設された前記係合支片５５の係合口部５４と対応するように突出形成されている。このフック７３は、弾性変形可能な係合片として機能する弾性片７３ａが２つ形成されてなり、各弾性片７３ａの先端部が摘み部７３ｂとされ、その摘み部７３ｂの表面上には係合部７３ｃが形成されている。また、前記トレー部材６７の上縁左端寄り（図６においては上縁右端寄り）には前記収容室２５側の施錠用板３５を挿通可能な横長の長孔７４が形成されると共に、前記トレー部材６７の左側縁には前記開閉支板１５側の支軸６２を挿通可能な軸孔７５が形成された上下一対の突片７６が一体形成されている。
【００２４】
従って、この保護ケース６９によりケース単位とされた主制御基板１６では、前記開閉支板１５の外面側において前記支軸６２に突片７６の軸孔７５を挿通支持させたもとで、前記支軸６２を支点として回動可能に支持されると共に、保護ケース６９の裏面すなわちトレー部材６７の裏面を開閉支板１５の外面に当接させた状態では、前記フック７３が開閉支板１５内側の係合口部５４に対して弾性的に嵌挿結合し（図７，図９参照）、二股状をなす前記弾性片７３ａの摘み部７３ｂを摘んで内方へ弾性変形させない限り、係合部７３ｃを利用した当該フック７３と前記係合口部５４との係合状態を解除できないようになっている。また、図７に例示するように開閉支板１５に対する保護ケース６９（主制御基板１６）の装着セット状態においては、前記長孔７４から更に外方へ先端部が突出してなる施錠用板３５の施錠用孔３６に対して管理者側で管理される正規鍵又は錠でもってしか解錠できない錠（例として南京錠）７７が挿通されて施錠される。そして、本実施形態では、前記係合口部５４とフック７３により係合手段７８が構成されると共に、そのフック７３により係合手段７８の係合支持部材が構成され、また前記施錠用孔３６を有する施錠用板３５と錠７７により錠手段が構成されている。

一方、前記主制御基板１６の保護ケース６９のカバー部材６８には、図２，３，５に示すように横長方形状をなす透視窓７９が形成されている。この透視窓７９は、図１１〜図１４に例示するように、前記カバー部材６８の一部が前記回路基板６６上の電子デバイス（ＣＰＵ，ＲＯＭ，ＲＡＭ等）６４と対応する位置で内面側へ直方体形状をなすように成形された凹み成形部８０の底部によって構成されている。そして、この透視窓７９を介して前記電子デバイス６４の表面に記された表記部８１の表記内容が視認可能になっていると共に、万一、前記電子デバイス６４が不正遊技者により他の不正電子デバイスに着脱交換されている場合の当該不正事実を発見し得るようになっている。
【００２６】
また、前記凹み成形部８０は、前記電子デバイス６４の表面と対向する対向面８２が当該電子デバイス６４との間に僅か（例えば１〜２mm程度）の距離しか確保されないように着脱制止部として成形されると共に、その凹み成形部８０の長手方向両端部には、図１１〜図１４から理解されるように、回路基板６６上の電子デバイス６４を僅か（例えば１〜２mm程度）な距離をおいて包囲する６つの制止脚部８３が移動制止部として前記対向面８２から突出するように形成されている。前記各制止脚部８３はその側面形状が、凹み成形部８０の内方側すなわち電子デバイス６４側となる辺を斜辺とする台形状に形成されており、その先端部（下端部）は回路基板６６の表面との間に極僅か（例えば１mm程度）の距離しか確保されないように成形されている。そして、本実施形態では、前記凹み成形部８０の対向面（着脱制止部）８２と制止脚部（移動制止部）８３により制止部８４が構成されている。従って、接合セットされたトレー部材６７とカバー部材６８とを無理に押し開けて、両者６７，６８の間から不正治具を差し入れて前記電子デバイス６４を不正脱着しようとしても、凹み成形部８０の対向面８２により電子デバイス６４の接続部６５からの着脱行為を制止できる一方、万一その接続部６５から電子デバイス６４が取外されたとしても、制止脚部８３によりその位置から当該電子デバイス６４を取出す行為を制止できるようになっている。
【００２７】
次に本実施形態のパチンコ遊技機の作用につき説明する。
さて、本実施形態のパチンコ機では外枠１から前枠２を回動開放して機裏側の機構セット盤９を露呈させたもとで、次のようにして払出し制御基板１９と主制御基板１６が機裏側に装着セットされる。尚、開閉支板１５については既に開閉連結支持手段４９により機構セット盤９の下部外側に開閉可能に支持されているものとし、主制御基板１６については装着セット前に回路基板６６等が保護ケース６９内に収容されたケース単位で取扱可能な形態とされているものとする。また、主制御基板１６を開閉支板１５の外面に装着セットする場合については、開閉支板１５が開放位置又は閉鎖位置のいずれの状態にあっても可能であるが、ここでは開放位置にある開閉支板１５に装着する場合を例にして説明する。
【００２８】
まず、払出し制御基板１９を収容室２５に装着セットするには、摘み部１５ａを把持して開閉支板１５を開放位置にすることにより収容室２５を露呈させる。そして、払出し制御基板１９の下端を基板載置片２６により支持させながら、同基板１９を左端側から収容室２５内に挿入してその左端を基板押え片２８に当てがって支持し、その状態から払い出し制御基板１９の右端を収容室２５側に押し込む。すると、収容室２５内の右側に位置するフック３３が払出し制御基板１９の右端に押されて左右方向へ弾性変形し、その弾性力に基づき払い出し制御基板１９を基板押え片２８側へ押しつけ支持する。従って、払出し制御基板１９は、基板載置片２６により下方から支持された状態において、収容室２５内にフック３３の摩擦係止作用を伴って基板押え片２８の先端部２８ａにより掛け止め保持される。
【００２９】
次に、主制御基板１６を開閉支板１５の外面に装着セットするには、その保護ケース６９における突片７６の軸孔７５を開閉支板１５における支持片６３の支軸６２に上方から挿入する。すると、主制御基板１６の保護ケース６９は開閉支板１５の外側に回動可能な状態に支持される（図１０参照）。そして、その状態から前記支軸６２を支点として保護ケース６９をその裏面が開閉支板１５の外面に近ずく方向へ回動させると、同ケース６９の裏面から突出形成されているフック７３が開閉支板１５の貫通孔５３を通過して、図７，９に示すように係合口部５４に嵌挿結合される。
【００３０】
前記各制御基板１９，１６の装着セット作業が終了すると、開閉支板１５が開放位置から閉鎖位置に回動される。すると、開閉支板１５は差込片５０が収容室２５側の係合片３０に摺動当接して同係合片３０を横向き外方へ若干弾性変形させる。そして、その状態から開閉支板１５が更に回動されて閉鎖位置に至ると、差込片５０の係合爪５１が係合片３０の係合孔２９に嵌合係止し、これにより開閉支板１５は閉鎖位置に係止保持される。また、この開閉支板１５の閉鎖位置への回動に伴い、収容室２５側から突出する施錠用板３５は保護ケース６９におけるトレー部材６８の長孔７３を通過して施錠用孔３６が形成された先端部を外部に突出させる。そこで、この施錠用孔３６に錠７７を施錠すると、開閉支板１５は前記閉鎖位置において開放不能状態とされる。
【００３１】
一方、この開閉支板１５を閉鎖位置に施錠した状態から前記主制御基板１６と払出し制御基板１９を取外す場合は、前記錠７７が解錠された後、開閉支板１５が開き動作される。即ち、収容室２５の左端から横向き外方へ出ている係合解除用の摘み部３１が更に横向き外方へ押されて、係合片３０の係合孔２９に対する差込片５０の係合爪５１の係止状態が解除される。そして、その状態から開閉支板１５の摘み部５２が把持されて開き方向へ回動されると開閉支板１５は開放位置とされる。
【００３２】
そして、この開閉支板１５が開放位置とされたもとで、主制御基板１６を取外す場合は、開閉支板１５の内面側において指先操作により前記フック７３の二股状をなす弾性片７３ａの摘み部７３ｂが摘まれて同フック７３の係合部７３ｃと係合口部５４との係合状態が解除され、主制御基板１６の保護ケース６９の裏面が開閉支板１５の外面から離間する方向へ回動させられる。すると、前記フック７３が開閉支板１５の貫通孔５３から抜け出るため、その状態から保護ケース６９を上方に持ち上げると、前記支軸６２から突片７６の軸孔７５が外れて主制御基板１６は開閉支板１５から取外される。
【００３３】
また、同様に開閉支板１５が開放位置とされたもとで、払出し制御基板１９を取外す場合は、収容室２５内のフック３３を払出し制御基板１９から離間する方向へ弾性変形させながら、同基板１９を右方へ若干移動してその左端における基板押え片２８の掛け止め保持状態を解除する。そして、その状態において払出し制御基板１９を把持すれば同基板１９は収容室２５内から容易に取出される。
【００３４】
従って、以上のように構成された本実施形態のパチンコ遊技機によれば、次のような効果を奏し得る。
（１）開閉支板１５の外面側に装着された主制御基板１６は錠（錠手段）７７が解錠されて開閉支板１５が開放状態とされない限り（軸４８は抜取れない）開閉支板１５の内側において係合手段７８を構成する係合口部５４とフック７３との係合状態を解除できないので、不正遊技者により前枠２が外枠１から回動開放されて機裏側の前記主制御基板１６が露呈された場合でも、主制御基板１６の不正脱着を確実に阻止することができる。
【００３５】
（２）また前記主制御基板１６は、その保護ケース（ケース体）６９の裏面から突出させたフック（係合支持部材）７３が開閉支板１５の外側から貫通孔５３に貫通支持されると共に、その貫通支持状態において開閉支板１５の内側に位置する係合口部（他の遊技機構成要素）５４に係合する構成であるため、前記開閉支板１５の貫通孔５３に対するフック（係合支持部材）７３の貫通支持構造でもって主制御基板１６をケース体単位で開閉支板１５に掛け止め支持することができる。
【００３６】
（３）また前記施錠用板３５と錠７７からなる錠手段を解錠した場合は、開閉支板１５を開放位置に回動開放することにより簡単に開閉支板１５の内側における係合手段７８が露呈するので、その係合手段７８の係合状態、即ち、係合口部５４に対するフック７３の係合状態を容易に解除して、主制御基板１６を保護ケースごと容易に開閉支板１５から取外すことができる。
【００３７】
（４）しかも、主制御基板１６の保護ケース６９は開閉支板１５の外面上に支軸６２を支点として回動可能に支持された構成であるため、保護ケース６９内に収容された回路基板６６の裏面側（回路パターン等がある）を点検するときには、いちいち保護ケース６９を開閉支板１５から持ち上げなくても前記支軸６２を支点として回動させるだけで簡単にその点検作業を行うことができる。そして、その状態から主制御基板１６の保護ケース６９を開閉支板１５側へ閉じ動作させて前記フック７３を貫通孔５３に挿通させれば、フック７３が係合口部５４に弾性変形を伴って嵌挿結合されるため指先によるワンタッチ操作で主制御基板１６を開閉支板１５に装着セットすることができる。
【００３８】
（５）さらにパチンコ遊技機の厚さ方向（前後方向）において前記主制御基板１６及び電飾制御基板１８と一部重合する配置状態で収容室２５内に収容されている払出し制御基板１９を着脱交換等する際には、前記主制御基板１６及び電飾制御基板１８を開閉支板１５に装着セットした状態のままで当該支板１５を開放位置へ回動させれば前記収容室２５の開口面域を露呈させることができるので、前記払出し制御基板１９の着脱交換作業を迅速容易に行うことができる。
【００３９】
（６）一方、前記払出し制御基板１９については、基板載置片２６により下方から支持しつつフック３３による弾性的な摩擦係止作用および基板押え片２８による掛け止め保持作用を付与して収容室２５内に位置決め装着することができるので、ビス等の取付用部品を省略できて払出し制御基板１９の装着セット構成を簡素化することができる。一方、収容室２５から払出し制御基板１９を取り出す際には前記フック３３の弾性力に抗して該基板１９を移動させることにより基板押え片２８の掛け止め保持状態を解除すれば簡単に収容室２５から該基板１９を取り出せるので、より一層着脱交換作業を迅速に行うことができる。
【００４０】
（７）また前記開閉支板１５を閉鎖位置から開放位置に回動開放する際には、係合解除用の摘み部３１を摘んで係合片３０を横向き外方へ弾性変形させることにより当該係合片３０の係合孔２９に対する開閉支板１５側の係合爪５１の嵌合係止状態が解除されるので、開閉支板１５はその摘み部５２を把持して簡単に開放位置側へ回動開放することができる。また反対に、開放位置にある開閉支板１５を閉鎖位置に閉鎖セットする際には、開閉支板１５の閉じ動作に伴い同支板１５の差込片５０が前記係合片３０に摺動当接して当該係合片３０を横向き外方へ弾性変形させるので、前記係合孔２９と係合爪５１とを自動的に嵌合係止させて開閉支板１５を簡単に閉鎖セット状態にできる。
【００４１】
（８）しかも前記開閉支板１５は、その素材が導電性を有する鉄板により構成されているため、当該開閉支板１５により電磁波を遮断して前記主制御基板１６の回路基板６６等を好適に保護することができる。そして、この開閉支板１５については、前述した主制御基板１６等の支持機能を有する部材構成と前記電磁波遮断機能を有する部材構成との兼用部材構成とされているため、パチンコ遊技機における部品点数を少なくしてコスト低減に貢献することができる。
【００４２】
（９）また主制御基板１６においては、保護ケース６９のカバー部材６８に凹み成形部８０を形成することにより透視窓７９を設け、この透視窓７８によって保護ケース６９内に収容した回路基板６６上の電子デバイス６４の表記部８１を一目瞭然に視認できるので、電子デバイス６４が不正脱着されているような場合には、その不正事実の発見を迅速容易に行うことができる。
【００４３】
（１０）しかも前記凹み成形部８０の電子デバイス６４との対向面８２は電子デバイス６４との間の距離が僅かしか確保されないように近接配置されているので、不正遊技者が針金等を保護ケース６９のトレー部材６７とカバー部材６８との間に差し込んで前記電子デバイス６４を回路基板６６上の接続部６５から回路基板６６と直交する方向へ脱着しようとしても、その脱着に必要なスペースをなくして当該不正脱着を有効に阻止することができる。さらに前記接続部６５から電子デバイス６４が万一脱着されたとしても、その電子デバイス６４を包囲するように僅かの距離をおいて近接配置された制止脚部８３が移動制止部として脱着位置から当該電子デバイス６４が回路基板６６と平行な方向へ移動されるのを阻止しているので、より確実に当該不正脱着行為を有効に阻止することができる。
【００４４】
（１１）また着脱制止部として機能する前記対向面８２及び移動制止部として機能する静止脚部８３は、いずれも前記電子デバイス６４の表面に直接接触する構成でなく、当該電子デバイス６４から僅かの距離をおいて近接配置される構成であるため、トレー部材６７に対するカバー部材６８の接合セット時に前記対向面８２及び制止脚部８３によって電子デバイス６４に対し機械的損傷を与えたりすることがないばかりか、正規の着脱交換作業に基づき新たに接続部６５へ接続セットされた交換後の純正電子デバイスが規格的に少々サイズの異なるものであったとしても、それらのサイズ的な違いは前記僅かの距離により吸収することができる。しかも、制止脚部８３は直方体形状をなす凹み成形部８０から側面形状が台形状をなす短かな板片とされ、針金等の不正治具により簡単には折ることができない構成になっているので、制止部としての機能を確実に果たすことができる。
【００４５】
なお前記実施形態におけるパチンコ遊技機は次のように構成を変更して具体化してもよい。
例えば、前記実施形態では開閉支板１５の外面に支軸６２を有する支持片６３を設ける一方、主制御基板１６の保護ケース６９には前記支軸６２に対応する軸孔７５の形成された突片７６を設け、これらの構成により主制御基板１６を開閉支板１５に対して回動可能に支持したが、これを図１５に示すような支持構成としてもよい。即ち、この図１５に示す別例においては、保護ケース６９におけるトレー部材６７の裏面三箇所からフック７３を突出形成し、これら各フック７３と対応する位置で、開閉支板１５には貫通孔５３が３つ形成されると共に、同支板１５の内面には係合口部５４を一つ備えた装着片５５が３つ取付固定されている。
【００４６】
従って、この別例においては、主制御基板１６における保護ケース６９側の各フック７３を開閉支板１５の各貫通孔５３に位置合わせして挿入すれば、前記実施形態の場合と同様に、開閉支板１５の内側で各係合口部５４と各フック７３が互いに嵌挿結合して錠７７を解錠して開閉支板１５を開放位置にしない限り、前記各係合口部５４と各フック７３からなる係合手段７８の係合解除をできないようにできる。また開閉支板１５に対して適数個（図示３つ）のフック７３が係合支持部材として機能するので主制御基板１６の保護ケース６９を開閉支板１５に対して同様に掛け止め支持することができる。
【００４７】
また前記実施形態では装着片５５の係合口部５４とフック７３により係合手段７８を構成したが、これを図１６に示すような構成としてもよい。即ち、この図１６の別例では、主制御基板１６の保護ケース６９におけるトレー部材６７の裏面から先端部に鉤状部８５が形成されたフック部材８６を係合支持部材として突出形成し、開閉支板１５には前記鉤状部８５の通過を許容する形状の貫通孔８７を形成している。そして、開閉支板１５の内面側に形成したボス部８８にはビス８９を介して前記フック部材８６の鉤状部８５に係止可能なロックレバー９０を回動可能に支持すると共に、このロックレバー９０の先端部には同ロックレバー９０を常には前記フック部材８６と当接する方向へ付勢するバネ９１の一端を取着している。
【００４８】
従って、この別例においては、前記ロックレバー９０をバネ９１の付勢力に抗して図１６（ｂ）における時計方向へ回動させた状態において、前記フック部材８６の鉤状部８５を開閉支板１５の外側から貫通孔８７に挿入して開閉支板１５の内側に突出させる。そして、その状態において前記ロックレバー９０をバネ９１の付勢力に基づき図１６（ｂ）における反時計方向へ回動させれば、前記フック部材８６の鉤状部８５にロックレバー９０が係止するので、前記実施形態の場合と同様に、錠７７を解錠して開閉支板１５を開放位置にしない限り、前記鉤状部８５とロックレバー９０からなる係合手段７８の係合解除をできないようにできる。また係合支持部材として機能するフック部材８６を利用して主制御基板１６の保護ケース６９を開閉支板１５に対して掛け止め支持できる。
【００４９】
さらに前記実施形態における係合手段７８は、これを図１７に示すような構成としてもよい。即ち、この図１７の別例では、主制御基板１６の保護ケース６９におけるトレー部材６７の裏面に横長の係止孔９２が形成された係合受け部９３を一体形成し、開閉支板１５には前記係止孔９２に対応する形状の貫通孔９４を形成している。そして、係合支持部材としての軸部９５の先端に前記係止孔９２及び貫通孔９４に挿入可能な一対の係止部９６を軸部９５と直交する方向へ形成した係止具９７を利用し、その係止具９７の軸部９５を前記貫通孔９４及び係止孔９２に開閉支板１５の内面側から挿入した後、前記係止具９７を９０度だけ回転操作することにより前記係合受け部９３の係止孔９２に前記係止部９６を係合するようにしている。
【００５０】
従って、この別例においても、前記実施形態の場合と同様に、錠７７を解錠して開閉支板１５を開放位置にしない限り、前記係止具９７を回動操作できないため、係止孔９２と係止部９６とからなる係合手段７８の係合解除をできないようにできる。また係合支持部材として機能する軸部９５を利用して主制御基板１６の保護ケース６９を開閉支板１５に対して掛け止め支持できる。
【００５１】
また前記実施形態では開閉支板１５を鉄板により構成したが、導電性を有して電磁波遮断効果を発揮するものであれば、銅板等の他の金属板を使用してもよい。さらに、開閉支板１５については平板形状のものに限定されず、多数の孔が形成された多孔板形状のものでもよく、その場合は開閉支板１５の軽量化に貢献することができる。
【００５２】
また開閉支持板１５の開閉連結支持手段４９については、前記実施形態におけるカール状軸受け４６，４７と支ピン４８からなる構成に限定されず、開閉支板１５を機構セット盤９の下部外側に開閉可能に支持し得る構成であれば、様々な蝶番構成を開閉連結支持手段４９として採用し得る。そして、その開閉連結支持手段４９については前記実施形態のように支ピン４８の圧入によって解離不能な構成としてもよく、また合鍵により解離可能な蝶番構成としてもよい。
【００５３】
また前記実施形態では主制御基板１６の保護ケース６９に施錠用板３５が挿通する長孔７４を形成したが、この長孔７４は開閉支板１５に形成してもよい。この場合にも錠７７を解錠しない限り開閉支板１５を開放位置へ回動できないので、前記実施形態と同様に開閉支板１５内側の係合手段７８について付勢遊技者による係合解除を不能にできる。
【００５４】
また開閉支板１５の内側に（パチンコ機から見ると前側に）、前記錠７７とは別の施錠手段又はカバー等を付設して、開閉支板１５が万一不正に開放されても、不正遊技者が開閉支板１５内側の係合手段７８を手早く簡単には係合解除できないようにしてもよい。
【００５５】
【発明の効果】
本願請求項１の発明によれば、万一不正に機裏側の機構セット盤が露呈された場合でも、錠を解錠することにより閉鎖位置にある開閉支板を開放位置にしない限り、開閉支板の内側で係合する係合手段の係合状態を解除できないので、開閉支板の外側に組付けセットされた主制御基板が不正に脱着される事態を防止できる。
【００５６】
また、本願請求項２の発明によれば、前記請求項１の発明の効果に加えて、開閉支板を簡単に開放位置側へ回動開放することができるとともに、開閉支板を簡単に閉鎖セット状態にすることができる。
【００５７】
また、本願請求項３の発明によれば、前記請求項２の発明の効果に加えて、主制御基板の裏面側を点検するときには、いちいち保護ケースを開閉支板から持ち上げなくても支軸を支点として回動させるだけで簡単にその点検作業を行うことができる。
また、本願請求項４の発明によれば、前記請求項２又は請求項３の発明の効果に加えて、機構セット盤に取り付けられるインターフェースボードの取り外しを容易に行うことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a pachinko gaming machine having a control board related to the control of a pachinko game developed on an in-machine game board on the back side of the machine.
[0002]
[Prior art]
With this type of gaming machine represented by pachinko machines and arrange ball machines, the game ball sent from the upper ball tray to the launch position is played by the ball feed launch operation for each ball that is started based on the game operation. You can hit the board and play the required pachinko game. A control board (removable main control board as a typical example) that is detachably attached to the mechanism set board on the back side of the machine in various winning conditions and special game conditions that are generated and established during the game. On the basis of the control command signal from, for example, an electrical game component such as a variable symbol display device or an electric winning device is controlled in accordance with each movable condition.
[0003]
In such a conventional gaming machine, the control board is a case unit in which a circuit board related to control of the pachinko game is housed in a protective case made of a synthetic resin composed of a tray member and a cover member that are separable from each other. The unit configuration is such that it can be handled separately from other game machine components. When mounting on the mechanism set board, as a general example, the fixing stopper attached to the tray member or cover member in the protective case is engaged with the engaging portion formed at a predetermined portion of the set board. By doing so, the immobilization was maintained. In addition, regarding the control board mounted in this way, the tray member constituting the protective case in order to be able to detect unauthorized modification performed on the control board at the time of inspection and inspection maintenance of the government. In order to leave a trace when the protective case is illegally opened with respect to the joint portion between the cover member and the cover member, a seal stamp is attached, or it is connected with a stopper (screw) that cannot be illegally operated.
[0004]
[Problems to be solved by the invention]
However, in the fixing stopper as described above, the front frame, which is also a mounting frame of the gaming machine, is rotated and released from the set state with respect to the outer frame by an unauthorized player, and the back side of the machine is exposed. The engagement state with respect to the engagement portion can be released, and it is possible for such an unauthorized player to remove the control board from the gaming machine (mechanism set board) relatively easily. For the removed control board, the seal stamp paper is easily peeled off using a special chemical or the like, or the tray member and the cover member are separated and opened by a dedicated jig. There has been a situation in which genuine electronic devices (for example, CPU, ROM, RAM, etc.) can be replaced with illegal electronic devices in which game data, winning probability data, etc. have been tampered with.

To do. Then, the protective case 69 of the main control board 16 is supported so as to be rotatable to the outside of the opening / closing support plate 15 (see FIG. 10). Then, when the protective case 69 is rotated in such a state that the back surface thereof is close to the outer surface of the opening / closing support plate 15 with the support shaft 62 as a fulcrum, the hook 73 protruding from the back surface of the case 69 is opened and closed. It passes through the through hole 53 of the support plate 15 and is fitted and coupled to the engagement port portion 54 as shown in FIGS.
[0030]
When the mounting and setting work of the control boards 19 and 16 is completed, the opening / closing support plate 15 is rotated from the open position to the closed position. Then, in the opening / closing support plate 15, the insertion piece 50 is brought into sliding contact with the engagement piece 30 on the housing chamber 25 side, and the engagement piece 30 is slightly elastically deformed laterally outward. When the opening / closing support plate 15 is further rotated from this state to reach the closed position, the engaging claw 51 of the insertion piece 50 is fitted and locked in the engaging hole 29 of the engaging piece 30, thereby opening and closing. The support plate 15 is locked and held in the closed position. As the opening / closing support plate 15 rotates to the closed position, the locking plate 35 protruding from the storage chamber 25 side passes through the long hole 73 of the tray member 68 in the protective case 69 to form the locking hole 36. The tip end is projected to the outside. Therefore, when the lock 77 is locked in the locking hole 36, the opening / closing support plate 15 is made unopenable in the closed position.
[0031]
On the other hand, when the main control board 16 and the payout control board 19 are removed from the state where the opening / closing support plate 15 is locked in the closed position, the opening / closing support plate 15 is opened after the lock 77 is unlocked. That is, the engagement releasing knob 31 protruding laterally outward from the left end of the storage chamber 25 is further pushed laterally outward, and the insertion piece 50 is engaged with the engagement hole 29 of the engagement piece 30. The locked state of the claw 51 is released. And if the knob | pick part 52 of the opening-and-closing support plate 15 is hold | gripped from that state and it rotates in an opening direction, the opening-and-closing support plate 15 will be made into an open position.
[0032]
When the main control board 16 is to be removed while the opening / closing support plate 15 is in the open position, the knob 73b of the elastic piece 73a that is bifurcated with the hook 73 by the fingertip operation on the inner surface side of the opening / closing support plate 15. And the engagement state between the engagement portion 73c of the hook 73 and the engagement port portion 54 is released, and the back surface of the protective case 69 of the main control board 16 rotates in a direction away from the outer surface of the opening / closing support plate 15. Be made. Then, since the hook 73 comes out of the through hole 53 of the opening / closing support plate 15, when the protective case 69 is lifted upward from this state, the shaft hole 75 of the projecting piece 76 is detached from the support shaft 62, and the main control board 16 is moved. It is removed from the opening / closing support plate 15.
[0033]
Similarly, when the payout control board 19 is removed with the opening / closing support plate 15 in the open position, the hook 19 in the storage chamber 25 is elastically deformed in a direction away from the payout control board 19 while the board 19 is being removed. Is slightly moved rightward to release the latch holding state of the substrate pressing piece 28 at the left end. If the dispensing control board 19 is gripped in this state, the board 19 can be easily taken out from the storage chamber 25.
[0034]
Therefore, according to the pachinko gaming machine of the present embodiment configured as described above, the following effects can be obtained.
(1) The main control board 16 mounted on the outer surface side of the opening / closing support plate 15 is open / closed unless the lock (locking means) 77 is unlocked and the opening / closing support plate 15 is opened (the shaft 48 cannot be removed). Since the engagement state between the engagement port portion 54 constituting the engagement means 78 and the hook 73 cannot be released on the inner side of the plate 15, the front frame 2 is rotated and released from the outer frame 1 by an unauthorized player, and the above-mentioned on the back side of the machine Even when the main control board 16 is exposed, unauthorized removal of the main control board 16 can be reliably prevented.
[0035]
(2) The main control board 16 has a hook (engagement support member) 73 protruding from the back surface of the protective case (case body) 69 and is supported through the through hole 53 from the outside of the opening / closing support plate 15. In the through-supporting state, the hook is engaged with the through-hole 53 of the opening / closing support plate 15 because it is configured to engage with an engagement port portion (another game machine component) 54 located inside the opening / closing support plate 15. The main control board 16 can be hooked and supported on the opening / closing support plate 15 in a case body unit with the through support structure of the support member 73.
[0036]
(3) When the locking means composed of the locking plate 35 and the lock 77 is unlocked, the engagement means 78 inside the opening / closing support plate 15 can be easily achieved by rotating the opening / closing support plate 15 to the open position. Therefore, the engagement state of the engagement means 78, that is, the engagement state of the hook 73 with respect to the engagement port portion 54 is easily released, and the main control board 16 can be easily removed from the opening / closing support plate 15 together with the protective case. Can be removed.
[0037]
(4) In addition, since the protective case 69 of the main control board 16 is rotatably supported on the outer surface of the opening / closing support plate 15 with the support shaft 62 as a fulcrum, the circuit board accommodated in the protective case 69 When inspecting the back surface side of 66 (there is a circuit pattern or the like), the inspection is simply performed by rotating the support shaft 62 as a fulcrum without lifting the protective case 69 from the opening / closing support plate 15 each time. Can do. Then, when the protective case 69 of the main control board 16 is closed from the state to the opening / closing support plate 15 side and the hook 73 is inserted into the through hole 53, the hook 73 is elastically deformed in the engagement port portion 54. Since it is inserted and connected, the main control board 16 can be mounted and set on the opening / closing support plate 15 by one-touch operation with a fingertip.
[0038]
(5) Further, the payout control board 19 accommodated in the accommodation chamber 25 in a state of being partially overlapped with the main control board 16 and the illumination control board 18 in the thickness direction (front-rear direction) of the pachinko gaming machine is attached and detached. When exchanging, the main control board 16 and the illumination control board 18 are mounted and set on the opening / closing support plate 15, and the support plate 15 is rotated to the open position to open the storage chamber 25. Since the surface area can be exposed, the work for attaching and detaching the payout control board 19 can be performed quickly and easily.
[0039]
(6) On the other hand, the dispensing control board 19 is provided with an elastic friction locking action by the hook 33 and a latch holding action by the board pressing piece 28 while being supported by the board mounting piece 26 from below. Therefore, it is possible to omit mounting parts such as screws and to simplify the mounting set configuration of the payout control board 19. On the other hand, when the payout control board 19 is taken out from the accommodation chamber 25, the accommodation chamber can be easily obtained by releasing the latch holding state of the substrate pressing piece 28 by moving the board 19 against the elastic force of the hook 33. Since the substrate 19 can be taken out from 25, the attaching and detaching / replacement operation can be performed more quickly.
[0040]
(7) When the opening / closing support plate 15 is pivotally opened from the closed position to the open position, the engagement piece 30 is elastically deformed laterally outward by picking the knob 31 for releasing the engagement. Since the engagement claw 51 of the engagement claw 51 on the opening / closing support plate 15 side with respect to the engagement hole 29 of the engagement piece 30 is released, the opening / closing support plate 15 grasps the knob 52 and can be easily opened. Can be rotated and released. On the other hand, when the opening / closing support plate 15 in the open position is closed and set in the closed position, the insertion piece 50 of the support plate 15 slides on the engagement piece 30 as the opening / closing support plate 15 is closed. Since the engagement piece 30 is elastically deformed laterally outward by abutting, the engagement hole 29 and the engagement claw 51 are automatically fitted and locked so that the opening / closing support plate 15 can be easily put into a closed set state. it can.
[0041]
(8) Moreover, since the material of the opening / closing support plate 15 is composed of an iron plate having conductivity, the circuit board 66 of the main control board 16 is suitably cut off by the opening / closing support plate 15 to block electromagnetic waves. Can be protected. The opening / closing support plate 15 has a member structure that is a combination of the member structure having the supporting function of the main control board 16 and the like and the member structure having the electromagnetic wave shielding function, so the number of parts in the pachinko gaming machine This can contribute to cost reduction.
[0042]
(9) Further, in the main control board 16, a see-through window 79 is provided by forming a recessed molding portion 80 in the cover member 68 of the protection case 69, and on the circuit board 66 accommodated in the protection case 69 by the see-through window 78. Therefore, when the electronic device 64 is illegally attached / detached, it is possible to quickly and easily find the fraudulent fact.
[0043]
(10) Furthermore, since the facing surface 82 of the dent molding portion 80 facing the electronic device 64 is disposed close to the electronic device 64 so that only a small distance is ensured, the illegal player can protect the wire and the like. Even if the electronic device 64 is inserted between the tray member 67 and the cover member 68 of 69 and is detachable from the connection portion 65 on the circuit board 66 in the direction orthogonal to the circuit board 66, the space necessary for the detachment is eliminated. Thus, the illegal desorption can be effectively prevented. Further, even if the electronic device 64 is detached from the connecting portion 65, the restraining leg portion 83 that is disposed close to the electronic device 64 at a slight distance so as to surround the electronic device 64 is the moving restraining portion from the removal position. Since the electronic device 64 is prevented from moving in a direction parallel to the circuit board 66, the illegal desorption action can be effectively prevented more reliably.
[0044]
(11) The opposing surface 82 functioning as an attachment / detachment restraining portion and the stationary leg portion 83 functioning as a movement restraining portion are not configured to be in direct contact with the surface of the electronic device 64, but slightly from the electronic device 64. Since the configuration is such that the cover member 68 is joined to the tray member 67, the electronic device 64 is not mechanically damaged by the facing surface 82 and the restraining leg 83 when the cover member 68 is joined and set. Even if the genuine electronic devices after replacement that are newly connected and set to the connection portion 65 based on regular attachment / detachment replacement work are slightly different in size, the difference in size is slightly different from the above. Can be absorbed by distance. In addition, the restraining leg portion 83 is a short plate piece having a trapezoidal side surface from the dent-shaped portion 80 having a rectangular parallelepiped shape, and is configured so that it cannot be easily folded by an illegal jig such as a wire. Thus, the function as a stopping portion can be surely achieved.
[0045]
The pachinko gaming machine in the above embodiment may be embodied by changing the configuration as follows.
For example, in the above-described embodiment, the support piece 63 having the support shaft 62 is provided on the outer surface of the opening / closing support plate 15, while the protective case 69 of the main control board 16 has a protrusion in which the shaft hole 75 corresponding to the support shaft 62 is formed. Although the piece 76 is provided and the main control board 16 is rotatably supported with respect to the opening / closing support plate 15 by these structures, this may be a support structure as shown in FIG. That is, in another example shown in FIG. 15, hooks 73 are formed so as to protrude from three positions on the back surface of the tray member 67 in the protective case 69, and through holes 53 are formed in the opening / closing support plate 15 at positions corresponding to these hooks 73. Are formed, and three mounting pieces 55 each having one engagement port portion 54 are attached and fixed to the inner surface of the support plate 15.
[0046]
Therefore, in this alternative example, if the hooks 73 on the protective case 69 side of the main control board 16 are inserted in alignment with the through holes 53 of the opening / closing support plate 15, the opening / closing is performed as in the case of the above embodiment. As long as each engagement port portion 54 and each hook 73 are inserted and coupled to each other inside the support plate 15 and the lock 77 is unlocked so that the opening and closing support plate 15 is not in the open position, each engagement port portion 54 and each hook 73 is provided. It is possible to prevent the engagement means 78 made of from being disengaged. Since an appropriate number (three in the figure) of hooks 73 function as engagement support members with respect to the opening / closing support plate 15, the protective case 69 of the main control board 16 is similarly latched and supported on the opening / closing support plate 15. be able to.
[0047]
In the above embodiment, the engaging means 78 is configured by the engaging port portion 54 and the hook 73 of the mounting piece 55, but this may be configured as shown in FIG. That is, in another example of FIG. 16, a hook member 86 having a hook-like portion 85 formed at the tip from the back surface of the tray member 67 in the protective case 69 of the main control board 16 is formed as an engaging support member, and is opened and closed. The support plate 15 is formed with a through hole 87 having a shape that allows passage of the hook-shaped portion 85. A boss portion 88 formed on the inner surface side of the opening / closing support plate 15 supports a lock lever 90 that can be engaged with the hook-shaped portion 85 of the hook member 86 via a screw 89 so as to be rotatable. One end of a spring 91 that urges the lock lever 90 in a direction to always abut against the hook member 86 is attached to the tip of the lever 90.
[0048]
Therefore, in this alternative example, the hook-shaped portion 85 of the hook member 86 is opened and closed in a state where the lock lever 90 is rotated clockwise in FIG. 16B against the urging force of the spring 91. It is inserted into the through hole 87 from the outside of the plate 15 and protrudes to the inside of the opening / closing support plate 15. If the lock lever 90 is rotated counterclockwise in FIG. 16B based on the urging force of the spring 91 in this state, the lock lever 90 is engaged with the hook-shaped portion 85 of the hook member 86. Therefore, as in the case of the above embodiment, unless the lock 77 is unlocked and the opening / closing support plate 15 is set to the open position, the engagement means 78 composed of the hook-shaped portion 85 and the lock lever 90 cannot be released. You can Further, the protective case 69 of the main control board 16 can be hooked and supported with respect to the opening / closing support plate 15 by using the hook member 86 functioning as an engagement support member.
[0049]
Furthermore, the engaging means 78 in the above embodiment may be configured as shown in FIG. That is, in another example of FIG. 17, an engagement receiving portion 93 in which a horizontally long locking hole 92 is formed on the back surface of the tray member 67 in the protective case 69 of the main control board 16 is integrally formed on the opening / closing support plate 15. A through hole 94 having a shape corresponding to the locking hole 92 is formed. Then, a locking tool 97 in which a pair of locking portions 96 that can be inserted into the locking holes 92 and the through holes 94 is formed in the direction perpendicular to the shaft portion 95 at the tip of the shaft portion 95 as an engagement support member is used. Then, after inserting the shaft portion 95 of the latching tool 97 into the through hole 94 and the latching hole 92 from the inner surface side of the opening / closing support plate 15, the latching tool 97 is rotated by 90 degrees to perform the engagement. The locking portion 96 is engaged with the locking hole 92 of the receiving portion 93.
[0050]
Therefore, also in this other example, as in the case of the above embodiment, the locking tool 97 cannot be rotated unless the lock 77 is unlocked and the opening / closing support plate 15 is set to the open position. It is possible to prevent the engagement means 78 composed of 92 and the locking portion 96 from being disengaged. Further, the protection case 69 of the main control board 16 can be latched and supported with respect to the opening / closing support plate 15 by using the shaft portion 95 functioning as an engagement support member.
[0051]
In the embodiment, the opening / closing support plate 15 is made of an iron plate. However, other metal plates such as a copper plate may be used as long as they have conductivity and exhibit an electromagnetic wave shielding effect. Further, the opening / closing support plate 15 is not limited to a flat plate shape, and may be a porous plate shape in which a large number of holes are formed.
[0052]
The open / close connection support means 49 of the open / close support plate 15 is not limited to the configuration comprising the curled bearings 46 and 47 and the support pin 48 in the above embodiment, and the open / close support plate 15 is opened and closed to the lower outside of the mechanism set panel 9. Various hinge configurations can be adopted as the opening / closing connection support means 49 as long as they can be supported. The open / close connection support means 49 may be configured so as not to be dissociable by press-fitting the support pin 48 as in the above-described embodiment, or may be configured as a hinge that can be dissociated by a key.
[0053]
In the above embodiment, the long hole 74 through which the locking plate 35 is inserted is formed in the protective case 69 of the main control board 16, but the long hole 74 may be formed in the opening / closing support plate 15. Also in this case, the opening / closing support plate 15 cannot be rotated to the open position unless the lock 77 is unlocked. Can be disabled.
[0054]
In addition, a locking means or a cover other than the lock 77 is provided on the inside of the opening / closing support plate 15 (on the front side when viewed from the pachinko machine). The player may not be able to disengage the engaging means 78 inside the opening / closing support plate 15 quickly and easily.
