Description

【０００１】
【発明の属する技術分野】
この発明は、パチンコ機、スロットルマシン等の遊技機に関し、主としてパチンコ機の制御基板取付台を、制御基板と共に覆う新規な裏カバー装置に関する。
【０００２】
【従来の技術】
従来、例えば、遊技機としてのパチンコ機において、遊技盤の裏面には、中継基板を覆うようにして制御基板取付台が開閉可能に組み付けられるとともに保持手段によって閉じ状態に保持されている。また、制御基板取付台には制御基板を収納した制御基板収納ボックスが装着されている。前記制御基板の不正改造、例えば不正ＲＯＭの交換を防止するために、制御基板収納ボックスには様々な工夫が施されている。一般的には、制御基板収納ボックスのボックス本体とボックスカバーとの両者間に跨って封印シールを貼り付けておくことにより、ボックスカバーの開放そのものを禁止して制御基板の不正改造等の不正行為を防止している。万一、ボックスカバーが不測に開けられ、制御基板に対し不正行為が行われた場合には、封印シールが切断あるいは剥離されていることを確認することで、前記不正行為が行われた事実を容易に認識できるようになっていた。
【０００３】
【発明が解決しようとする課題】
ところで、前記従来の構造においては、封印シールさえ剥がせばボックスカバーを開放することが可能となる。このため、封印シールが剥離されてボックスカバーが開かれ、制御基板の不正改造等の不正行為が行われた後、再度、封印シールが巧妙に貼り付けられると、不正行為の事実を発見することが困難となり、制御基板に対する不正行為が不測に行われてしまうという問題があった。また、制御基板取付台においては、その保持手段が外されることで制御基板取付台を開放することが可能となる。このため、保持手段が外されかつ制御基板取付台が開放されることから、遊技盤の裏面の中継基板やその配線等に対しても不正行為が不測に行われてしまうという問題があった。
【０００４】
この発明の目的は、前記従来の問題点に鑑み、制御基板に対する不正行為あるいは、中継基板やその配線等に対する不正行為を簡単な構造によって確実に防止することができる遊技機を提供することである。
【０００５】
【課題を解決するための手段】
前記目的を達成するために、請求項１の発明に係る遊技機は、木枠に開閉可能に組み付けられた前枠の開口部周縁裏側に沿って取り付けられるベース枠内に各種の遊技用電気部品を配置した遊技盤が嵌め込まれる一方、前記遊技盤の裏面側に装着される制御基板取付台の周囲を取り囲むように枠状に形成される裏セット板が前記ベース枠の裏側に開閉自在に取り付けられ、さらに前記制御基板取付台の裏面に前記遊技用電気部品を制御する制御基板を収納する制御基板収納ボックスが設置されると共に、該制御基板収納ボックスを覆う裏カバー体が前記制御基板取付台に着脱自在に取り付けられる遊技機において、前記制御基板取付台は、前記遊技盤の裏面に向けて開口しかつ周壁部と前記制御基板収納ボックスが取り付けられる台板部とを備えて箱形状に形成されると共に、前記周壁部の一側の両端部分に前記遊技盤の裏面にビスによって取り付けられる有底筒状であって弾性的に縮開可能に所定数の割溝によって形成された弾性係止部と係合する筒状の係合部が形成される一方、前記周壁部の他側辺に沿って薄肉で一体の取付台ヒンジによって結合された取付部が一体形成され、該取付部の両端部分に有底筒状でビスによって前記遊技盤の裏面に止着されるボス部が形成され、さらに前記周壁部の一側の中程に水平状に係合部が突設される一方、前記周壁部の他側の中程に封印部材が挿通される係止孔が貫設され、前記裏カバー体は、前記遊技盤の裏面に向けて開口しかつ周壁部と蓋板部とを備えて前記制御基板収納ボックス及び前記制御基板取付台を覆う大きさの箱形状に形成されると共に、前記周壁部の一側両端部に前記有底筒状の弾性係止部に嵌め込まれる拘束部が突設される第１フランジ部が張り出される一方、前記周壁部の他側両端部に前記有底筒状のボス部に嵌め込まれる嵌合凸部が突設される第２フランジ部が張り出され、さらに前記周壁部の一側の中程に前記水平状の係合部と係合する断面鉤形状の係止フックが形成される一方、前記周壁部の他側の中程に前記封印部材が挿通される挿通孔が貫設され、前記ボス部をビスで止着し且つ前記弾性係止部に係合部を係合させて前記制御基板取付台が前記遊技盤の裏面に取り付けられた状態で、前記裏カバー体の拘束部を前記有底筒状の弾性係止部に嵌め合せながら前記断面鉤形状の係止フックを前記水平状の係合部に係合させるように回転させ、その回転を引き続いて行って前記嵌合凸部を前記有底筒状のボス部に嵌め込み、その後、前記封印部材を前記挿通孔及び前記係止孔に挿通することにより、前記裏カバー体を前記制御基板取付台に取り付け、この取付状態において前記制御基板取付台の前記係合部と弾性係止部との係合状態が、前記裏カバー体の拘束部の当該弾性係止部への嵌め合せにより解除できないようにしたことを特徴とする。したがって、裏カバー体によって制御基板収納ボックスと制御基板取付台とが覆われているため、制御基板に対する不正行為が防止される。また、裏カバー体が閉じ状態にあるときには、制御基板取付台の係合部と弾性係止部との係合状態が裏カバー体の拘束部の当該弾性係止部への嵌め合せにより解除できないようにしたため、制御基板取付台が不測に開放されることが防止される。
【０００６】
【０００７】
【発明の実施の形態】
（実施の形態１）
この発明の実施の形態１を図１〜図１１にしたがって説明する。パチンコ機の略中央部を底面側から視た断面で表した図１及びパチンコ機を背面から表した図２において、遊技機としてのパチンコ機１は、その木枠２の前側に前枠３が開閉可能に装着されている。前枠３の開口部の前側にはガラス扉の扉枠８が組み付けられている。また、前枠３の裏面には、その開口部の周縁部においてベース枠４が組み付けられている。ベース枠４の枠内には遊技盤２０が着脱可能に嵌込まれている。この遊技盤２０には、図示しない賞球装置、役物装置、表示装置等が配設されている。さらに、遊技盤２０の裏面の中央部には、球の裏誘導路３０を有する球誘導ケース３１や役物装置に対する役物基板（図示しない）等が組み付けられている。この球誘導ケース３１の裏面側には、前記賞球装置、役物装置、表示装置に組み込まれた電機部品（ソレノイド、モータ、ランプ類等）に対し接続ケーブル３３によって接続された中継基板３２が組み付けられている。この中継基板３２は、後述の制御基板収納ボックス６１の内部に収納された制御基板６０に対し接続ケーブル３５によって接続されている。また、遊技盤２０は、その裏面の周縁部に配設された裏セット機構９の主体部をなす裏セット板１０によってベース枠４の支持面５に押し付けられて保持されている。
【０００８】
前記裏セット機構９の主体部をなす裏セット板１０は、次に述べる制御基板取付台５０の周囲を取り囲むようにして枠状に構成されている。そして、裏セット板１０は、その一側（図１及び図２に向かって右側）において裏セットヒンジ６によってベース枠４の一側に開閉可能に組み付けられている。さらに、裏セット板１０は、その自由端側（図１及び図２に向かって左側）において複数の締め具７によってベース枠４に対し係脱可能に締め付けられている。これによって裏セット板１０がベース枠４に対し、閉じ状態に保持されている。また、裏セット板１０には、球タンク１１、タンクレール１２、賞品球排出装置１３等が配設され、これによって裏セット機構９が構成されている。
【０００９】
前記遊技盤２０の裏面の中央部には、前記球誘導ケース３１、役物基板（図示しない）、中継基板３２等を覆うようにして制御基板取付台５０が装着されている。図１と図４の（Ａ）〜（Ｃ）に示すように、制御基板取付台５０は、合成樹脂の射出成形によって成形され、遊技盤２０の裏面に向けて開口しかつ周壁部５１と台板部５２とを備えて箱形状に形成されている。この制御基板取付台５０の台板部５２には、前記中継基板３２と制御基板６０とを接続する接続ケーブル３５が挿通されるケーブル挿通孔（図示しない）が形成されている。制御基板取付台５０の周壁部５１は、開口側が広く台板部５２側が狭い複数段の断面段差状に形成されている。さらに、周壁部５１のうち、その一側（図４では左側）壁部の上下方向には、薄肉で一体の取付台ヒンジ４０によって結合された取付部５３が一体成形されている。前記取付部５３は、その上下両端部寄りに有底筒状のボス部５３ａが形成され、そのボス部５３ａにおいて、ビス５５によって遊技盤２０の裏面に固定されている。制御基板取付台５０は、その周壁部５１及び台板部５２が前記取付台ヒンジ４０を中心として開閉回動可能に組み付けられている。なお、取付台ヒンジ４０は、一般には本実施の形態のように、賞品球排出装置１３に近接する壁部とは反対側に配設され、制御基板取付台５０の開閉回動時における賞品球排出装置１３との干渉が回避されるようになっている。
【００１０】
図３と図４の（Ａ）〜（Ｃ）に示すように、前記制御基板取付台５０の他側の上下部と、これに対向する遊技盤２０の裏面部分との間には、遊技盤２０の裏面に対し制御基板取付台５０を閉じ状態に係脱可能に保持する保持手段７０が配設されている。前記保持手段７０は、遊技盤２０の裏面にビス７７によって取り付けられた弾性係止部７１と、制御基板取付台５０の他側の上下部に形成された係合部７５とを備えている。弾性係止部７１は、その先端側に開口する中心孔７２を備えた有底筒状に形成されるとともに、弾性的に縮開可能に所要数の割溝が形成されている。さらに、弾性係止部７１の先端部外周には断面三角形状の係止爪７４が形成されている。
【００１１】
これに対し、係合部７５は、前記弾性係止部７１が弾性的に差し込まれる係合孔を中心に有する両端開口の段差筒状に形成されている。そして、図４の（Ｂ）に示すように、係合部７５の係合孔に弾性係止部７１が弾性的に縮小されながら所定位置まで差し込まれることで、その弾性係止部７１の係止爪７４が係合孔の段差状係止部７６に係合する。この係止爪７４と段差状係止部７６との係合力に基づいて遊技盤２０の裏面に対し制御基板取付台５０が閉止状態で保持されるようになっている。
【００１２】
図１と図４の（Ｂ）に示すように、前記制御基板取付台５０の台板部５２には、制御基板６０が収納された制御基板収納ボックス６１が適宜の取付手段によって取り付けられている。この制御基板収納ボックス６１は、制御基板６０を装着したボックス本体６２と、そのボックス本体６２の開口部を塞ぐようにして装着されたボックスカバー６３とを備えている。そして、ボックス本体６２に対しボックスカバー６３は、これら両者間に跨って配設された封印シールや封印ネジ等によるボックス封印手段よって封印されている。なお、ボックスカバー６３の周壁部及び蓋板部には放熱用の多数の貫通孔６５、６６が貫設されている。
【００１３】
図１に示すように、前記遊技盤２０の裏側には前記制御基板収納ボックス６１を覆う裏カバー体８１を備えた裏カバー装置８０が配設されている。この実施の形態１において、前記裏カバー体８１は合成樹脂の射出成形によって成形され、制御基板取付台５０とともに制御基板取付台５０を覆う大きさの箱形状に形成されている。そして、裏カバー体８１は、遊技盤２０の裏面に向けて開口しかつ周壁部８２と蓋板部８４とを備えている。裏カバー体８１の周壁部８２は、開口側が広く蓋板部８４側が狭い複数段の断面段差状に形成されている。これによって、図６に示すように、裏カバー体８１は、所定の嵌込み代をもって上下に積み重ね可能に形成され、運搬、保管、収納等の取り扱いが容易となっている。なお、制御基板取付台５０においても、所定の嵌込み代をもって上下に積み重ね可能に複数段の断面段差状に形成されている。
【００１４】
図７と図８に示すように、前記裏カバー体８１の周壁部８２のうち、その一側（図１と図３では右側）壁部の略中央部の先端縁には、断面鉤形状の係止フック８６が形成されている。また、図７と図８に示すように、制御基板取付台５０の周壁部５１のうち、前記係止フック８６に対応する側には、係止フック８６に係脱可能に係合する係合部４５が形成されている。また、裏カバー体８１の周壁部８２の一側上下部には第１フランジ部８８が張り出され、他側の上下部には、第２フランジ部８９が張り出されている。図３と図４の（Ｂ）及び（Ｃ）に示すように、裏カバー体８１の第１フランジ部８８の前面には、弾性係止部７１の中心孔７２に嵌込まれる拘束部１０１が突設されている。そして、この拘束部１０１によって遊技盤２０の裏面に対し制御基板取付台５０を離脱不能に保持する外れ防止手段１００が構成されている。また、図３と図５に示すように、裏カバー体８１の第２フランジ部８９には、制御基板取付台５０の取付部５３に突設された閉止フック９０が係脱可能に差し込まれる閉止孔９１が形成されている。さらに、裏カバー体８１の第２フランジ部８９の前面には、制御基板取付台５０の取付部５３のボス部５３ａに嵌込まれて制御基板取付台５０に対し裏カバー体８１を位置決めする嵌合凸部１０５が突設されている。
【００１５】
すなわち、前記裏カバー体８１は、まず、第１フランジ部８８前面の拘束部１０１が制御基板取付台５０に形成された弾性係止部７１の中心孔７２に嵌込まれる。この際、図７に示すように、裏カバー体８１の係止フック８６は、制御基板取付台５０の係合部４５の斜め下方に位置し、裏カバー体８１は、制御基板取付台５０に対し傾いた姿勢を取る。そして、弾性係止部７１の中心孔７２に拘束部１０１が嵌込まれながら裏カバー体８１が遊技盤２０の裏面に向けて回動されると、図８に示すように、裏カバー体８１の係止フック８６が制御基板取付台５０の係合部４５に係合する。引き続く裏カバー体８１の回動によって、ボス部５３ａに嵌合凸部１０５が嵌込まれて制御基板取付台５０に対し裏カバー体８１の位置決めがなされ、これと略同時に、閉止フック９０が閉止孔９１に差し込まれて弾性的に係合する。これによって、図１と図４の（Ｃ）に示すように、制御基板取付台５０に裏カバー体８１が開閉並びに着脱可能に組み付けられ、同制御基板取付台５０の制御基板収納ボックス６１が裏カバー体８１によって覆われるようになっている。
【００１６】
前記制御基板取付台５０と裏カバー体８１との間には、裏カバー体８１を開放不能に封印するための封印手段１１０が配設されている。この実施の形態１において、図３に示すように、前記封印手段１１０は、封印用錠１１１と封印部材１２０とを備え、裏カバー体８１が二重に封印されるようになっている。前記封印用錠１１１並びに封印部材１２０は、裏カバー体８１の周壁部８２のうちの一側壁部の中間段差部８３とこれに対向する制御基板取付台５０の台板部５２の一側寄り上面との間にそれぞれ配設されている。
【００１７】
すなわち、図９の（Ａ）及び（Ｂ）に示すように、制御基板取付台５０の台板部５２の一側寄り上面には、ループ状をなす施錠用突部１１５が突設されている。これに対し、裏カバー体８１の一側壁部の中間段差部８３には前記施錠用突部１１５が挿脱可能に差し込まれる施錠用孔１１４が形成されている。そして、施錠用孔１１４に施錠用突部１１５が差し込まれ、封印用錠１１１の錠本体１１２から延出された錠フック１１３が前記施錠用突部１１５を通して錠本体１１２に施錠されることで、制御基板取付台５０に対し裏カバー体８１が封印されるようになっている。
【００１８】
また、図１に示すように、封印用錠１１１によって制御基板取付台５０に対し裏カバー体８１が封印された状態において、封印用錠１１１は、裏セットヒンジ６を中心とする裏セット機構９の開閉軌跡に交差する方向に配置されるようになっている。そして、図１の２点鎖線に示すように、裏セット機構９の開放が、封印用錠１１１によって僅かな開き角度に規制されている。
【００１９】
また、図３、図１０、図１１の（Ａ）及び（Ｂ）に示すように、封印部材１２０は、裏カバー体８１の中間段差部８３と、これに対向する制御基板取付台５０の台板部５２の一側寄り上面との間にわたって挿通されることで、制御基板取付台５０に対し裏カバー体８１を封印するものである。この封印部材１２０は、方形板状の基部１２１と、その基部１２１の一側面から直角状に突設された脚部１２２とを一体に備え、脚部１２２の先端部には断面三角形状の係止部１２３が形成されている。また、裏カバー体８１の中間段差部８３の表面には、封印部材１２０の基部１２１が嵌込まれる凹部１３１を有する装着座部１３０が形成され、その装着座部１３０の凹部１３１の中央部には封印部材１２０の脚部１２２が挿通される挿通孔１３２が貫設されている。さらに、制御基板取付台５０の台板部５２の一側寄り上面には、封印部材１２０の脚部１２２が挿通されかつ係止部１２３と係合して封印部材１２０の抜け止めをなす断面略テーパ状の係止孔１３５が貫設されている。
【００２０】
すなわち、封印部材１２０の脚部１２２先端の係止部１２３が、装着座部１３０の凹部１３１の挿通孔１３２を通して係止孔１３５に押し込み動作されることで、その係止孔１３５を弾性的に拡開させながら係止部１２３を通過する。そして、封印部材１２０の脚部１２２先端の係止部１２３が係止孔１３５を通過したところで、係止孔１３５が元の状態に弾性復帰し、これによって係止部１２３と係止孔１３５と係合し、その係合力に基づいて制御基板取付台５０に対し裏カバー体８１が封印されるようになっている。
【００２１】
また、この実施の形態１において、図１１の（Ｂ）に示すように、封印部材１２０によって制御基板取付台５０に対し裏カバー体８１が封印された状態において、封印部材１２０の脚部１２２は、ニッパ等の切断工具によって容易に切断されるように、裏カバー体８１の外方（裏面側）に所定長さだけ突出される長さ寸法を有している。また、図１１の（Ｂ）に示すように、封印部材１２０の脚部１２２が装着座部１３０の凹部１３１の挿通孔１３２を通して係止孔１３５に押し込まれ、同封印部材１２０の基部１２１が凹部１３１底面に当接する押し込み端位置まで押し込まれたときには、基部１２１の表面が装着座部１３０の表面と略同一面をなすように、基部１２１の板厚寸法並びに凹部１３１の深さ寸法が適宜に設定されている。そして、基部１２１の表面が装着座部１３０の表面に跨って封印シール１４０が必要に応じて容易に貼り付けられるようになっている。
【００２２】
また、この実施の形態１において、図１と図３に示すように、裏カバー体８１の蓋板部８４には、制御基板収納ボックス６１のボックスカバー６３に対応する位置において放熱用開口窓８５が形成されている。そして、制御基板収納ボックス６１のボックスカバー６３の蓋板部に貫設された放熱用の多数の貫通孔６６による放熱作用が裏カバー体８１によって妨げられることなく前記放熱用開口窓８５を通して良好に行われるようになっている。
【００２３】
この実施の形態１のパチンコ機用制御ボックスの裏カバー装置は上述したように構成される。したがって、遊技盤２０の裏側には、制御基板取付台５０の制御基板収納ボックス６１を覆って裏カバー体８１が配設され、その裏カバー体８１が封印手段１１０によって閉じ状態に封印されている。このため、制御基板収納ボックス６１のボックスカバー６３が不測に開放されることが防止される。前記裏カバー体８１に対する封印手段１１０は、封印用錠１１１並びに封印部材１２０を備え、裏カバー体８１を二重に封印するようになっている。このため、仮に、封印用錠１１１が不測に解錠されたとしても、封印部材１２０によって裏カバー体８１を封印状態に保つことができる。また、封印部材１２０が破損されている場合には、その封印部材１２０の破損を確認することで、裏カバー体８１が不測に開放され制御基板収納ボックス６１の制御基板６０に対し不正行為が行われたことを想定することができる。このため、制御基板６０の構成部品が不正に取り替えられて不正行為がなされることを未然に防止することが可能となる。
【００２４】
制御基板収納ボックス６１の制御基板６０の検査や保守点検等を行う場合、封印用錠１１１においては、所定の管理者によって管理された鍵を用いて封印用錠１１１が解錠される。また、図１１の（Ａ）及び（Ｂ）に示すように、封印部材１２０においては、まず、封印シール１４０が剥がされる。次に、封印部材１２０の脚部１２２が裏カバー体８１の外方に所定長さだけ引き出されることで、その脚部１２２の引出部分がニッパ等の切断工具によって容易に切断される。したがって、封印用錠１１１並びに封印部材１２０の封印解除が容易にかつ手早く行われる。その後、裏カバー体８１が開放されて取り外された後、制御基板収納ボックス６１のボックスカバー６３が開放されることで制御基板収納ボックス６１に収納された制御基板６０の検査や保守点検等が行われる。
【００２５】
また、図１に示すように、封印用錠１１１によって制御基板取付台５０に対し裏カバー体８１が封印された状態において、封印用錠１１１は、裏セットヒンジ６を中心とする裏セット機構９の開閉軌跡に交差する方向に配置されている。このため、封印用錠１１１によって裏セット機構９の開放を僅かな開き角度に規制することができる。これによって、遊技盤２０と制御基板取付台５０との間の隙間を通して行われる不正行為、例えば、中継基板３２の接続ケーブル３３を不正部品に接続する不正行為あるいは役物基板（図示しない）等に対する不正行為が防止される。
【００２６】
また、この実施の形態１において、図４の（Ｃ）に示すように、裏カバー体８１の第１フランジ部８８の前面には、遊技盤２０の裏面に突設された弾性係止部７１の中心孔７２に嵌込まれる拘束部１０１が突設されている。このため、遊技盤２０の弾性係止部７１と制御基板取付台５０の係合部７５との係合が前記拘束部１０１によって保持される。すなわち、弾性係止部７１を弾性的に縮小させながら係合部７５が離脱することが前記拘束部１０１によって確実に防止される。このため、裏カバー体８１が取り外されない限り制御基板取付台５０が取付台ヒンジ４０を中心として開放されることがない。
【００２７】
また、図４の（Ｃ）に示すように、裏カバー体８１の第２フランジ部８９の前面には、制御基板取付台５０のボス部５３ａに嵌込まれて制御基板取付台５０に対し裏カバー体８１の位置決めをなす嵌合凸部１０５が突設されている。したがって、制御基板取付台５０のボス部５３ａと裏カバー体８１の嵌合凸部１０５との嵌合作用並びに前記弾性係止部７１と拘束部１０１との嵌合作用によって、遊技盤２０の裏側に対する裏カバー体８１の上下方向及び左右方向の位置ずれやガタツキが防止されるとともに、遊技盤２０の裏側の所定位置に裏カバー体８１が正確に位置決めされて保持される。
【００２８】
（実施の形態２）
次に、この発明の実施の形態２を図１２〜図１４にしたがって説明すると、この実施の形態２においは、裏カバー体８１の封印部材１２０において、その基部１２１の一側から裏セットヒンジ６を中心とする裏セット機構９の開閉軌跡に交差する方向に張出部１２４が延出されている。そして、封印部材１２０の張出部１２４によって裏セット機構９の開放が僅かな開き角度に規制されるようになっている。これによって、遊技盤２０と制御基板取付台５０との間の隙間を通して行われる不正行為、例えば、中継基板３２の接続ケーブル３３を不正部品に接続する不正行為あるいは役物基板等に対する不正行為が防止される。その他の構成は実施の形態１と同様に構成されるため、その説明は省略する。
【００２９】
（実施の形態３）
次に、この発明の実施の形態３を図１５〜図１７にしたがって説明すると、この実施の形態３においては、図１５に示すように、遊技盤２０の裏面に開閉可能に組み付けられた制御基板取付台５０を閉じ状態に保持するための保持手段７０においても裏カバー体８１の一部によって覆うことで、その保持手段７０が外部から不測に外されることがないように構成したものである。また、この実施の形態３において、図１６と図１７に示すように、制御基板取付台５０の周壁部５１の一側先端部には、フランジ部５６が張り出されている。このフランジ部５６には、保持手段７０としての保持部材７８が嵌挿される係止孔５７が形成され、この係止孔５７の直径方向には保持部材７８の摘み兼用の押付片７９が挿脱可能な離脱孔部５８が形成されている。
【００３０】
これに対し、保持手段７０としての保持部材７８は、取付ネジ７３に対する段差状の取付孔を中心部に備えた円筒状に形成され、遊技盤２０の裏面に取付ネジ７３を中心として回動可能に取り付けられている。前記保持部材７８にはその外周面の直径方向には、制御基板取付台５０のフランジ部５６を遊技盤２０の裏面に対し押え付ける摘み兼用の押付片７９が突設されている。そして、図１６の２点鎖線に示すように、保持部材７８の摘み兼用の押付片７９が制御基板取付台５０のフランジ部５６の係止孔５７の離脱孔部５８に一致する離脱位置に配置された状態において、遊技盤２０の裏面側に対し、制御基板取付台５０が開閉可能となる。また、図１６の実線に示すように、保持部材７８の摘み兼用の押付片７９が前記離脱位置から略９０度回動された保持位置に配置されたときには、その摘み兼用の押付片７９が前記フランジ部５６の係止孔５７に係合してそのフランジ部５６を遊技盤２０の裏面に押し付ける。これによって、遊技盤２０の裏面に開閉可能に組み付けられた制御基板取付台５０を閉じ状態に保持するようになっている。
【００３１】
