更に、スタートレバーＢＬがオン操作されるのに応じて主制御基板７００がいわゆる役抽選を行い、ストップボタンＢＰ１，ＢＰ２，ＢＰ３がストップ操作されるのに応じて、主制御基板７００の制御下で回胴装置基板９００が各メインリールＭＲ１，ＭＲ２，ＭＲ３を停止時間τ内に停止させるのであるが、この停止時間τの間に、各メインリールＭＲ１，ＭＲ２，ＭＲ３に描かれている図柄を最大で３コマ分ずらして停止させることにより、上述の抽選された役に相当する３個の図柄を第１透明窓ＷＤ１の有効ラインＬ１上に揃えるようにしている。
【０１０５】
つまり、例えば上述の抽選された役に相当する図柄の組み合わせが、メインリールＭＲ１，ＭＲ２，ＭＲ３の順に「スイカ」−「ぶどう」−「レモン」であったとすると、ストップボタンＢＰ１がストップ操作された時点から停止時間τ内に、メインリールＭＲ１を最大で３つの図柄分（最大３コマ分）だけ回転させることにより、その回転中に図柄「スイカ」を有効ラインＬ１上に揃えることとしている。また、ストップボタンＢＰ２がストップ操作された時点から停止時間τ内に、メインリールＭＲ２を最大で３つの図柄分だけ回転させることにより、その回転中に図柄「ぶどう」を有効ラインＬ１上に揃えることとしている。また、ストップボタンＢＰ３がストップ操作された時点から停止時間τ内に、メインリールＭＲ３を最大で３つの図柄分だけ回転させることにより、その回転中に図柄「レモン」を有効ラインＬ１上に揃えることとしている。
【０１０６】
このように、ストップボタンＢＰ１，ＢＰ２，ＢＰ３がストップ操作された時点における図柄を含めて夫々の停止時間τの間に、図柄を最大で３コマ分ずらしてから停止させることによって、遊技者に対し違和感を与えないように停止させることとしている。
【０１０７】
また、ストップボタンＢＰ１，ＢＰ２，ＢＰ３がストップ操作された時点では、第１透明窓ＷＤ１の有効ラインＬ１上に、例えば上述の３つの図柄「スイカ」−「ぶどう」−「レモン」が全て揃うことは確率的に希であるが、夫々のメインリールＭＲ１，ＭＲ２，ＭＲ３を最大３コマ分ずらしている間に、３つの図柄「スイカ」−「ぶどう」−「レモン」を有効ラインＬ１上に揃えられるようにしている。
【０１０８】
なお、各メインリールＭＲ１，ＭＲ２，ＭＲ３を停止させる際にずらす図柄の数（コマ数）を制御コマ数Ｎｚと呼んで以下説明することとし、本実施形態では上述したように制御コマ数Ｎｚを、次式（３）で表されるように最大３個に決めている。
【０１０９】
【数３】

【０１１０】
つまり、Ｎｚ≦３個とは、制御コマ数Ｎｚを最大で３個まで許容するという意味であり、ストップ操作された時点に、停止させるべき図柄（抽選された役に相当する図柄）が有効ラインＬ１上に来た場合には、その時点で各メインリールＭＲ１，ＭＲ２，ＭＲ３を停止させ、一方、ストップ操作された時点に、停止させるべき図柄が有効ラインＬ１上に来なかった場合には、停止時間τの間に各メインリールＭＲ１，ＭＲ２，ＭＲ３を１つの図柄分又は２つの図柄分回転させ、それによって停止させるべき図柄が有効ラインＬ１上に来た場合には、そこで各メインリールＭＲ１，ＭＲ２，ＭＲ３を停止させるという意味である。
【０１１１】
また、遊技者にとって視認性を良くするために、各テープリールＭＴＰ１，ＭＴＰ２，ＭＴＰ３に描かれている各図柄の大きさ、すなわち縦幅Ｈと横幅Ｗの大きさを次式（４−ａ）（４−ｂ）に示すように、夫々２５ｍｍ以上及び３５ｍｍ以上に決めている。
【０１１２】
【数４】

【０１１３】
そして、上記式（１）（２）（３）（４−ａ）（４−ｂ）の条件を満足すべく、メインリールＭＲ１，ＭＲ２，ＭＲ３の夫々の直径Ｒと、各テープリールＭＴＰ１，ＭＴＰ２，ＭＴＰ３に描かれている図柄の個数Ｋと、各図柄の大きさ（縦幅Ｈと横幅Ｗ）とを最適化した。
【０１１４】
まず、上記式（１）（２）（３）に示した回転数Ｎと停止時間τと制御コマ数Ｎｚ、及び図柄の個数Ｋの関係を求めると、次式（５）が求まる。
【０１１５】
【数５】

【０１１６】
ここで、ステッピンモータＭＭ１，ＭＭ２，ＭＭ３を制御する際、最も厳しい条件は、回転数Ｎが８０ｒｐｍの場合であり、更に最も安定して各メインリールＭＲ１，ＭＲ２，ＭＲ３を停止させ得る停止時間τは１９０ｍｓｅｃであることから、これらの値を上記式（５）に代入すると、
【数６】

となる。そして、この関係式（６）に基づいて図柄の個数Ｋを求めると、次式（７）に示すように、１１．８４個という値が得られ、よって、図柄の個数Ｋは１２個以上であることが望ましいという結果が得られる。
【０１１７】
【数７】

【０１１８】
そこで、再度上記式（６）を適用して、個数Ｋを１１個、１２個、１３個、１４個、１５個、１６個…とした場合の夫々の制御コマ数Ｎｚを求めてみると、
【数８】

となる。
【０１１９】
ここで、Ｋ＝１１のときの制御コマ数Ｎｚは３個に満たないので、上記式（３）の条件を十分には満足せず、Ｋ＝１２と、Ｋ＝１３と、Ｋ＝１４と、Ｋ＝１５のときの制御コマ数Ｎｚはほぼ３個となるので上記式（３）の条件を満足し、Ｋ＝１６のときの制御コマ数Ｎｚは４個となるので上記式（３）の条件を満足しないという結論を導出して、図柄の好適な個数Ｋを次式（８）で示すように、１２個以上１５個以下の何れかの自然数に決めることとした。
【０１２０】
【数９】

次に、上記式（８）で表される図柄の個数Ｋのうち、最適な個数Ｋを次の解析に基づいて決めた。
【０１２１】
まず、上述の条件を満足し得る小型のメインリール装置１００を実現すべく、各メインリールＭＲ１，ＭＲ２，ＭＲ３の円周Ｃと直径Ｒを上記式（８）の条件に従って求めると、１図柄の最小の縦幅Ｈは２５ｍｍであることから、
【０１２２】
【数１０】

という関係が得られる。
【０１２３】
したがって、各メインリールＭＲ１，ＭＲ２，ＭＲ３を製造するための製造精度等を考慮して、次式（９）に示すように、最小の直径Ｒを約９５ｍｍ程度、冗長とは成らない（大きすぎない）直径Ｒは約１２０ｍｍ程度という結論を得た。
【０１２４】
【数１１】

【０１２５】
ただし、上記式（９）で示される直径Ｒの値に基づいて、リールテープＭＴＰ１，ＭＴＰ２，ＭＴＰ３に図柄を描いたのでは、互いに隣接する図柄同士が見難くなってしまう。つまり、図柄と図柄との間に殆ど隙間が無い状態となるため、極めて見難くなり、互いに隣接する図柄を区別し難くなってしまう。
【０１２６】
そこで、最小公倍数的な直径Ｒである１２０ｍｍを最適な値の候補に決めて、図柄の個数Ｋを１２個、１３個、１４個、１５個とした場合の夫々の図柄のピッチ間隔ＰＰを求めると、
【数１２】

となる。
【０１２７】
ここで、図柄の個数Ｋを１２とした場合には、図柄を大きくし、更に互いに隣接する図柄間の隙間も大きくすることが可能であるが、冗長なリール構造となってなってしまう。また、図柄の個数Ｋを１５とした場合には、互いに隣接する図柄間に隙間が無くなって区別し難くなる等の問題を生じる。
【０１２８】
一方、図柄の個数Ｋを１３個又は１４個した場合には、図柄のピッチ間隔ＰＰにおける各図柄の縦幅Ｈと隙間を比較的自由に設定することができ、更に各図柄を見易くすることができる。
【０１２９】
そこで、図柄の個数Ｋを１５とした場合には、図柄間に約３ｍｍ程度の隙間を生じさせ且つ各メインリールＭＲ１，ＭＲ２，ＭＲ３の小型化の要請を考慮して、各メインリールＭＲ１，ＭＲ２，ＭＲ３の直径Ｒを１４０ｍｍと決め、各リールテープＭＴＰ１，ＭＴＰ２，ＭＴＰ３の長さＬを各メインリールＭＲ１，ＭＲ２，ＭＲ３の円周Ｃに合わせるべく約４４０ｍｍと決めることとした。したがって、最適な場合と好適な場合を含めると、次式（１０）に示すように、各メインリールＭＲ１，ＭＲ２，ＭＲ３の直径Ｒは約９５ｍｍ以上約１４０ｍｍ以下の範囲が良いという結論を得た。
【０１３０】
【数１３】

【０１３１】
また、本実施形態の最適な場合として、各メインリールＭＲ１，ＭＲ２，ＭＲ３の直径Ｒを約１２０ｍｍ（より具体的には、１２２ｍｍ）と決め、図柄の個数Ｋは、１４個とするよりも設計の自由度を高くすることが可能な１３個に決めることで、上記式（１）（２）（３）（４−ａ）（４−ｂ）の条件を満足すると共に、図柄間に隙間が生じる最適なリール構造を実現した。
【０１３２】
なお、最適な場合における１図柄の縦幅Ｈは２６ｍｍ、横幅Ｗは３５ｍｍにし、互いに隣接関係にある図柄間に隙間が生じるようにすることで、視認性の向上を実現している。
【０１３３】
以上、本実施形態の最も好適なメインリール装置１００の仕様を列記すると、
〔１〕メインリールＭＲ１〜ＭＲ３の定速回転時の回転数を、Ｎ≦８０ｒｐｍ
〔２〕メインリールＭＲ１〜ＭＲ３の各停止時間を、τ≦１９０ｍｓｅｃ
〔３〕メインリールＭＲ１〜ＭＲ３の直径を、Ｒ＝１２２ｍｍ
〔４〕メインリールＭＲ１〜ＭＲ３の円周を、Ｃ＝３８３ｍｍ
〔５〕メインリールＭＲ１〜ＭＲ３の図柄の個数を、Ｋ＝１３個
〔６〕制御コマ数を、Ｎｚ≦３個
〔７〕図柄の種類を、制御コマ数Ｎｚの関係から５種類
〔８〕１図柄の縦幅をＨ＝２６ｍｍ、横幅をＷ＝３５ｍｍ
〔９〕図柄のピッチ間隔を、ＰＰ＝２９．５ｍｍ
〔１０〕リールテープＭＴＰ１〜ＭＴＰ３の長さをＬ＝３８３ｍｍ 、幅をＷＴ＝４４ｍｍ
〔１１〕ステッピングモータＭＭ１〜ＭＭ３の１回転当たりの制御ステップ数を４００ステップとし、各図柄当たりの回転角度を３０ステップ又は３１ステップで制御することとした。
【０１３４】
そして、上述のリールケース本体１０１とリールケースカバー１０２を上述の第１〜第３のメインリールユニットを収容するのに必要十分な大きさとなるように小型化することにより、全体的に小型のメインリール装置１００を実現した。
【０１３５】
このように、本実施形態のメインリール装置１００は、上述の最適化された小型のメインリールＭＲ１，ＭＲ２，ＭＲ３を備えることにより、視認性及び制御性が良好で且つ小型化が実現されている。
【０１３６】
次に、演出表示装置としてのサブリール装置２００の構造を図９及び図１０を参照して説明する。なお、図９は、サブリール装置２００の外観構造を表した斜視図、図１０は、サブリールＳＲ１，ＳＲ２，ＳＲ３の外周に捲装されているテープリールＳＴＰ１，ＳＴＰ２，ＳＴＰ３を示した展開図である。
【０１３７】
図９において、サブリール装置２００は、硬質プラスチックで成形された矩形状の支持ケース２０１内に、３個の円筒形状のサブリールＳＲ１，ＳＲ２，ＳＲ３が収容され、各サブリールＳＲ１，ＳＲ２，ＳＲ３の外周に、図１０に示すテープリールＳＴＰ１，ＳＴＰ２，ＳＴＰ３が捲装されている。
【０１３８】
そして、基本的には、上述のメインリール装置１００と同様のユニット構造によって、サブリールＳＲ１を回転駆動するステッピングモータ（符号略）と、サブリールＳＲ２を回転駆動するステッピングモータ（符号略）と、サブリールＳＲ３を回転駆動するステッピングモータＳＭ３が設けられ、更に、図９では省略しているが、支持ケース２０１の上端に、上述の各ステッピングモータを駆動する駆動回路基板６００が取り付けられている。
【０１３９】
ここで、各サブリールＳＲ１，ＳＲ２，ＳＲ３は、直径が約２３０ｍｍ、横幅が約８０ｍｍに設計され、夫々の外周面には、メインリールＭＲ１，ＭＲ２，ＭＲ３に描かれている図柄よりも大きな図柄が２１個ずつ描かれている。
【０１４０】
また、３個のサブリールＳＲ１，ＳＲ２，ＳＲ３が互いに接触することなく、回転軸方向に沿って横一列に設けられることで、各サブリールＳＲ１，ＳＲ２，ＳＲ３の横方向におけるピッチ間隔が約９０ｍｍ、これら３個のサブリールＳＲ１，ＳＲ２，ＳＲ３の全体の横幅が、約２７０ｍｍに設計されている。
【０１４１】
そして、ゲームの進行に応じて主制御基板７００から供給される制御信号に従って駆動回路基板６００が、各ステッピングモータＳＭ１，ＳＭ２，ＳＭ３にパルス幅制御を施した駆動電力を供給することにより、各ステッピングモータＳＭ１，ＳＭ２，ＳＭ３の正回転と逆転及び停止を行わせることにより、各サブリールＳＲ１，ＳＲ２，ＳＲ３の動きを様々に変化させ、それに伴って図柄の動きを変化させることにより演出表示を行う。
【０１４２】
次に、図１１のブロック図を参照して、本スロットマシン１０に設けられている制御システムについて説明する。
【０１４３】
まず、図２には説明の便宜上示されていないが、主制御基板７００には、回胴装置基板９００と、サブ制御基板３００、中央表示基板４００、電源装置基板５００及び外部集中端子基板８００が夫々配線ケーブルによって配線接続されている。また、サブ制御基板３００に駆動回路６００が配線接続されている。
【０１４４】
主制御基板７００は、半導体メモリＲＯＭと、マイクロプロセッサＭＰＵが搭載されており、当該マイクロプロセッサＭＰＵが、半導体メモリＲＯＭに予め記憶されているシステムプログラムとスロットマシンゲーム用のプログラムを実行し、各基板９００，３００，４００，５００，８００に所定の指令を行って夫々に分散制御を行わせることにより、本スロットマシン１０全体を集中制御する。
【０１４５】
回胴装置基板９００には、メインリールＭＲ１，ＭＲ２，ＭＲ３を回転駆動するステッピングモータＭＭ１，ＭＭ２，ＭＭ３が接続されている。そして、主制御基板７００からメインリールＭＲ１，ＭＲ２，ＭＲ３を回転又は停止させるべき旨の制御信号が供給されると、回胴装置基板９００はステッピングモータＭＭ１，ＭＭ２，ＭＭ３への電力供給を制御し、メインリールＭＲ１，ＭＲ２，ＭＲ３の動作を制御する。
【０１４６】
つまり、回胴装置基板９００は、主制御基板７００から回転開始を示唆する制御信号が供給されると、ステッピングモータＭＭ１，ＭＭ２，ＭＭ３を起動させ、メインリールＭＲ１，ＭＲ２，ＭＲ３を８０ｒｐｍ以下の定速度で回転させるべく制御する。
【０１４７】
また、回胴装置基板９００は、主制御基板７００からメインリールＭＲ１を停止させるべき制御信号が供給されると、ステッピングモータＭＭ１を制動制御し、停止時間τ内すなわち１９０ｍｓｅｃ内にメインリールＭＲ１を停止させる。また、有効ラインＬ１上に停止させるべき図柄が指定されて制御信号が供給されると、回胴装置基板９００は、停止時間τ内にメインリールＭＲ１を制御コマ数Ｎｚ分回転させ、指定された図柄が有効ラインＬ１上に揃うとメインリールＭＲ１を停止させる。
【０１４８】
また、主制御基板７００からメインリールＭＲ２を停止させるべき制御信号が供給されると、ステッピングモータＭＭ２を制動制御し、停止時間τ内にメインリールＭＲ１を停止させる。また、有効ラインＬ１上に停止させるべき図柄が指定されて制御信号が供給されると、停止時間τ内にメインリールＭＲ２を制御コマ数Ｎｚ分回転させ、指定された図柄が有効ラインＬ１上に揃うとメインリールＭＲ２を停止させる。
【０１４９】
また、主制御基板７００からメインリールＭＲ３を停止させるべき制御信号が供給されると、ステッピングモータＭＭ３を制動制御し、停止時間τ内にメインリールＭＲ３を停止させる。また、有効ラインＬ１上に停止させるべき図柄が指定されて制御信号が供給されると、停止時間τ内にメインリールＭＲ３を制御コマ数Ｎｚ分回転させ、指定された図柄が有効ラインＬ１上に揃うとメインリールＭＲ３を停止させる。
【０１５０】
サブ制御基板３００は、演出用ランプ１３ａ〜１３ｅ，１４ｂ，１４ｃ，１５ｂ，１５ｃとスピーカＱ１〜Ｑ４が接続され、主制御基板７００から演出開始を示唆する制御信号が供給されると、これら演出用ランプ１３ａ〜１３ｅ，１４ｂ，１４ｃ，１５ｂ，１５ｃとスピーカＱ１〜Ｑ４を駆動することによって、遊技者の視覚と聴覚に訴える演出を行う。また、主制御基板７００からは抽選した役が指令され、サブ制御基板３００は、その指令された役に相当する演出を演出用ランプ１３ａ〜１３ｅ，１４ｂ，１４ｃ，１５ｂ，１５ｃとスピーカＱ１〜Ｑ４によって行うことにより、遊技者に興味を与える効果的な演出を行うようになっている。
【０１５１】
更にサブ制御基板３００は、主制御基板７００から上述の演出開始を示唆する制御信号が供給されると、駆動回路基板６００に指令して、サブリール装置２００のステッピングモータＳＭ１，ＳＭ２，ＳＭ３を起動させ、サブリールＳＲ１，ＳＲ２，ＳＲ３を回転させることによる演出表示を行わせる。また、主制御基板７００から抽選した役が指令されると、サブ制御基板３００は駆動回路基板６００に指令して、ステッピングモータＳＭ１，ＳＭ２，ＳＭ３を起動させ、その指令された役に相当する演出をサブリールＳＲ１，ＳＲ２，ＳＲ３にて行わせる。
【０１５２】
中央表示基板４００は、ベットボタンＢＴ１，ＢＴ２と、スタートレバーＢＬ及びストップボタンＢＰ１，ＢＰ２，ＢＰ３が接続され、これらスイッチＢＴ１，ＢＴ２，ＢＬ，ＢＰ１，ＢＰ２，ＢＰ３から出力される出力信号を主制御基板７００へ転送する中継基板として機能する。また、中央表示基板４００は、セレクト機構Ｇ０に設けられている遊技メダル検出センサから出力される出力信号を主制御基板７００へ転送し、メダル投入部ＭＤに投入されたメダル枚数を知らせると共に、異物の投入や目詰まりの発生等を知らせる。
【０１５３】
そして、主制御基板７００は、ベットボタンＢＴ１，ＢＴ２がオン操作されると、１ゲーム当たりの賭け枚数を検知し、スタートレバーＢＬがオン操作されると、ゲーム開始の指示がなされたことを検知し、ストップボタンＢＰ１，ＢＰ２，ＢＰ３が任意の順番でストップ操作されると、その順番でメインリールＭＲ１，ＭＲ２，ＭＲ３を停止させるべき指示がなされたことを検知する。
【０１５４】
ここで、主制御基板７００が上述のスタートレバーＢＬがオン操作されたことを検知すると、役抽選を行った後、上述のメインリールＭＲ１，ＭＲ２，ＭＲ３を回転させるべく回胴装置基板９００に指令すると共に、サブ制御基板３００に指令して、演出用ランプ１３ａ〜１３ｅ，１４ｂ，１４ｃ，１５ｂ，１５ｃとスピーカＱ１〜Ｑ４及びサブリール装置２００による演出を行わせる。
【０１５５】
また、ストップボタンＢＰ１，ＢＰ２，ＢＰ３が任意の順番でストップ操作されると、主制御基板７００は、メインリールＭＲ１，ＭＲ２，ＭＲ３をストップ操作の順番で停止させ、且つ、上述したように抽選した役に相当する図柄を有効ラインＬ１上に揃えるべく回胴装置基板９００に指令する。また、主制御基板７００は、サブ制御基板３００に指令して、各ストップボタンＢＰ１，ＢＰ２，ＢＰ３がストップ操作される毎に、演出用ランプ１３ａ〜１３ｅ，１４ｂ，１４ｃ，１５ｂ，１５ｃとスピーカＱ１〜Ｑ４及びサブリール装置２００による演出を様々に変化させることにより、ゲームの進行状況等を遊技者に告知する。
【０１５６】
電源装置基板５００は、電源装置ＰＷＵで発生される各種電源電圧をホッパ装置ＨＰその他の各所に配電する配電回路が形成されており、かかる配電回路からスロットマシン１００の動作に必要なシステム電源を供給する。
【０１５７】
また、電源装置基板５００は、主制御基板７００から遊技メダルの払い出しをすべき旨の指令を受けると、ホッパ装置ＨＰを制御して遊技メダルの払い出しを行わせる。
【０１５８】
外部集中端子基板８００は、主制御基板７００から出力される本スロットマシン１０におけるゲームの進行状況等を示す信号を、上述のホールコンピュータへ送出する。
【０１５９】
次に、本スロットマシン１０の動作を図１２を参照して説明する。
【０１６０】
なお、図１２（ａ）は、本スロットマシン１０に備えられている役の種類と、各役に相当する図柄の組合せと、各役に入賞した際に払い出される遊技メダルの枚数等を関連付けて表した図、図１２（ｂ）は、役抽選の原理を表した模式図である。
【０１６１】
図１２（ａ）において、本スロットマシン１０には、シングルボーナス（ＳＢ）と呼ばれる特別役と、リプレイと呼ばれる再遊技役と、２つの小役すなわち小役〈１〉と小役〈２〉とが備えられている。
【０１６２】
シングルボーナス（ＳＢ）は、遊技者がベットボタンＢＴ１（又はＢＴ２）とスタートレバーＢＬとストップボタンＢＰ１，ＢＰ２，ＢＰ３を操作して１ゲームを行った結果、図８に示したメインリールＭＲ１，ＭＲ２，ＭＲ３の外周面に描かれている各図柄が、「スイカ」−「桃」−「桃」の組み合わせで第１透明窓ＷＤ１の有効ラインＬ１（図１参照）上に揃って停止すると、遊技者に対し１３枚（つまり、賭け枚数の１３倍）の遊技メダルを払い出し、更に遊技者にとって有利にゲームを進行させる得る特典を提供する役である。
【０１６３】
リプレイは、遊技者がベットボタンＢＴ１（又はＢＴ２）とスタートレバーＢＬとストップボタンＢＰ１，ＢＰ２，ＢＰ３を操作して１ゲームを行った結果、図８に示したメインリールＭＲ１，ＭＲ２，ＭＲ３の外周面に描かれている各図柄が、「ぶどう」−「ぶどう」−「桃」の組み合わせで第１透明窓ＷＤ１の有効ラインＬ１上に揃って停止すると、遊技メダルの支払いを行わないが、遊技者にとって賭け枚数の提示を行うことなく、もう１度ゲームを行う特典を与える役である。
【０１６４】
小役〈１〉は、遊技者がベットボタンＢＴ１（又はＢＴ２）とスタートレバーＢＬとストップボタンＢＰ１，ＢＰ２，ＢＰ３を操作して１ゲームを行った結果、図８に示したメインリールＭＲ１，ＭＲ２，ＭＲ３の外周面に描かれている各図柄が、「スイカ」−「ぶどう」−「レモン」の組み合わせで第１透明窓ＷＤ１の有効ラインＬ１上に揃って停止すると、１３枚（つまり、賭け枚数の１３倍）の遊技メダルの支払いを行う役である。
【０１６５】
小役〈２〉は、遊技者がベットボタンＢＴ１（又はＢＴ２）とスタートレバーＢＬとストップボタンＢＰ１，ＢＰ２，ＢＰ３を操作して１ゲームを行った結果、図８に示したメインリールＭＲ１の外周面に描かれている「桃」の図柄が第１透明窓ＷＤ１の有効ラインＬ１上に揃って停止すると、３枚（つまり、賭け枚数の３倍）の遊技メダルの支払いを行う役である。つまり、小役〈２〉は、メインリールＭＲ１の「桃」の図柄が第１透明窓ＷＤ１の有効ラインＬ１上に揃うだけで入賞となり、残余のメインリールＭＲ２，ＭＲ３の図柄は何であっても、３枚（賭け枚数の３倍）の遊技メダルの支払いを行う役である。
【０１６６】
遊技者がベットボタンＢＴ１（又はＢＴ２）をオン操作して１ゲーム当たりの賭け枚数を提示して、スタートレバーＢＬをオン操作すると、主制御基板７００が１ゲームの制御を開始して役抽選を行う。
【０１６７】
この役抽選の際には、まず主制御基板７００中のマイクロプロセッサＭＰＵが乱数演算を行うことによって、最小の乱数値０から最大の乱数値ηｍａｘ（本実施形態では、６５５３５）の範囲内の１つの乱数値ηｉを内部発生する。
【０１６８】
そして、図１２（ｂ）に示すように、シングルボーナス（ＳＢ）とリプレイと小役〈１〉と小役〈２〉が最小の乱数値０から最大の乱数値ηｍａｘ内の所定の乱数値の範囲に対応付けて予め割り当てられており、マイクロプロセッサＭＰＵは、上述の内部発生した乱数値ηｉと予め割り当てられている夫々の乱数値の範囲とを対比して一致性を判定することにより、シングルボーナス（ＳＢ）とリプレイと小役〈１〉と小役〈２〉の何れか１つの役を抽選する。また、上述の内部発生した乱数値ηｉが、シングルボーナス（ＳＢ）とリプレイと小役〈１〉と小役〈２〉の何れの乱数値にも該当しない場合には、マイクロプロセッサＭＰＵは、ハズレを抽選する。
【０１６９】
例えば、マイクロプロセッサＭＰＵは、内部発生した乱数値ηｉが図１２（ｂ）に示す０≦ηｉ＜η１の関係を満足すると小役〈２〉を抽選し、η１≦ηｉ＜η２の関係を満足すると小役〈１〉を抽選し、η２≦ηｉ＜η３の関係を満足するとリプレイ（再遊技役）を抽選し、η３≦ηｉ＜η４の関係を満足するとシングルボーナス（ＳＢ）を抽選し、η４≦ηｉ＜ηｍａｘの関係を満足すると、その他の役又はハズレを抽選する。
【０１７０】
そして、ハズレに該当する乱数値の範囲が最も大きく、次に小役〈２〉、小役〈１〉、リプレイ（再遊技役）、シングルボーナス（ＳＢ）の順で次第に乱数値の範囲が小さくなっていくように予め決められることにより、ハズレの抽選確率が最も高く、シングルボーナス（ＳＢ）の抽選確率が最も小さくなっている。
【０１７１】
更に主制御基板７００は、役抽選を行う他、回胴装置基板９００に指令してメインリールＭＲ１，ＭＲ２，ＭＲ３を８０ｒｐｍ以下の所定速度で回転させ、更にサブ制御基板３００に指令して、サブリールＳＲ１，ＳＲ２，ＳＲ３を回転させると共に、演出用ランプ１３ａ〜１３ｅ，１４ｂ，１４ｃ，１５ｂ，１５ｃとスピーカＱ１〜Ｑ４を駆動させることによって、視覚と聴覚に訴える演出を開始する。
【０１７２】
次に、遊技者がストップボタンＢＰ１，ＢＰ２，ＢＰ３を任意の順番でストップ操作すると、主制御基板７００は、回胴装置基板９００に指令してメインリールＭＲ１，ＭＲ２，ＭＲ３を上述のストップ操作された順番で停止させ、更にサブ制御基板３００に指令して、サブリールＳＲ１，ＳＲ２，ＳＲ３の回転を変化させると共に、演出用ランプ１３ａ〜１３ｅ，１４ｂ，１４ｃ，１５ｂ，１５ｃの点灯及び点滅動作とスピーカＱ１〜Ｑ４の効果音も変化させることによって、遊技者のストップ操作に対応した視覚と聴覚に訴える演出を行う。
【０１７３】
ここで、主制御基板７００が上述の役抽選においてシングルボーナス（ＳＢ）を抽選していた場合には、回胴装置基板９００は、各メインリールＭＲ１，ＭＲ２，ＭＲ３の外周面に描かれている図柄を「スイカ」−「桃」−「桃」の組み合わせで第１透明窓ＷＤ１の有効ラインＬ１上に揃えるべく、ストップ操作された順番でステッピングモータＭＭ１，ＭＭ２，ＭＭ３を制動制御して、夫々を停止時間τ（すなわち、１９０ｍｓｅｃ）以内に停止させる。
【０１７４】
つまり、回胴装置基板９００は、停止時間τ以内に、制御コマ数Ｎｚの条件を満足しつつ、各メインリールＭＲ１，ＭＲ２，ＭＲ３の外周面に描かれている図柄を「スイカ」−「桃」−「桃」の組み合わせで有効ラインＬ１上に揃えて停止させるための制御を行う。
【０１７５】
ここで、メインリールＭＲ１が回転中であって、例えば図８に示したテープリールＭＴＰ１の一番下に描かれている「ぶどう」の図柄（符号ｔ１で示す図柄）が第１透明窓ＷＤ１の有効ラインＬ１上に位置したときに、遊技者がストップボタンＳＰ１をストップ操作したとすると、回胴装置基板９００は、制御コマ数Ｎｚが３個（Ｎｚ≦３）に設定されているので、メインリールＭＲ１を最大で３コマ分回転させ、その回転中にメインリールＭＲ１の「スイカ」の図柄が有効ラインＬ１上に位置すると、その時点でステッピングモータＭＭ１及びメインリールＭＲ１を停止させる。つまり、図８中の符号ｔ２で示されている「スイカ」の図柄が有効ラインＬ１上に位置すると、その時点でステッピングモータＭＭ１及びメインリールＭＲ１を停止させることにより、抽選されている役に相当する「スイカ」の図柄を的確に有効ラインＬ１上に停止させる。
【０１７６】
また、メインリールＭＲ１が回転中であって、例えば図８中の符号ｔ２で示す「スイカ」の図柄が第１透明窓ＷＤ１の有効ラインＬ１上に位置したときに、遊技者がストップボタンＳＰ１をストップ操作したとすると、回胴装置基板９００は、そのストップ操作された時点ｔ２においてメインリールＭＲ１を停止させる。また、符号ｔ２で示す「スイカ」の図柄が第１透明窓ＷＤ１の有効ラインＬ１上から殆ど離脱しているような場合には、制御コマ数Ｎｚが３個（Ｎｚ≦３）に設定されているので、メインリールＭＲ１を最大で３コマ分回転させて、符号ｔ３で示されている「スイカ」の図柄が有効ラインＬ１上に位置する時点でステッピングモータＭＭ１及びメインリールＭＲ１を停止させることにより、抽選されている役に相当する「スイカ」の図柄を的確に有効ラインＬ１上に停止させる。
【０１７７】
以下同様に、回胴装置基板９００は、制御コマ数Ｎｚが３個（Ｎｚ≦３）に設定されているので、ストップ操作された時点からメインリールＭＲ１を最大で３コマ分回転させ、その回転中にメインリールＭＲ１の「スイカ」の図柄が有効ラインＬ１上に位置すると、その時点でステッピングモータＭＭ１及びメインリールＭＲ１を停止させることにより、ほぼ確実に、抽選されたシングルボーナス（ＳＢ）役に相当する「スイカ」の図柄を有効ラインＬ１上に位置させて、ステッピングモータＭＭ１及びメインリールＭＲ１を停止させる。
【０１７８】
更に、他の小役〈１〉と小役〈２〉とリプレイ（再遊技）の何れかが抽選されていた場合でも、回胴装置基板９００は、シングルボーナス（ＳＢ）役の場合と同様に、制御コマ数Ｎｚと停止時間τの条件を満足しつつステッピングモータＭＭ１を制動制御することにより、ほぼ確実に、それらの役に相当する図柄（抽選された役が小役〈１〉の場合には「スイカ」、小役〈２〉の場合には「桃」、リプレイの場合には「ぶどう」）を有効ラインＬ１上に位置させて、ステッピングモータＭＭ１及びメインリールＭＲ１を停止させる。
【０１７９】
また、回胴装置基板９００は、ストップボタンＳＰ２，ＳＰ３がストップ操作された場合にも、上述のストップボタンＳＰ１がストップ操作された場合と同様に、制御コマ数Ｎｚと停止時間τの条件を満足しつつ、ステッピングモータＭＭ２，ＭＭ３を制動制御することにより、ほぼ確実に、抽選された役に相当する図柄を有効ラインＬ１上に位置させて、ステッピングモータＭＭ２，ＭＭ３及びメインリールＭＲ２，ＭＲ３を停止させる。
【０１８０】
そして、主制御基板７００は、メインリールＭＲ１，ＭＲ２，ＭＲ３の３個の図柄が、図１２（ａ）に示したように、抽選した役に相当する組み合わせで有効ラインＬ１上に揃って止まると、入賞が確定したと判断して、電源装置基板５００に指令して所定枚数の遊技メダルの払い出し等を行わせる。
【０１８１】
また、主制御基板７００は、サブ制御基板３００に指令して、入賞の確定を告知するための演出を行わせた後、１ゲーム分の制御を完了して、遊技者が次のゲームを開始するまで待機する。そして、スタートレバーＢＬ等がオン操作されると、次のゲームの進行を制御する。
【０１８２】
このように本実施形態のスロットマシン１０によれば、演出を行うために備えられている上部パネル部１３と中部パネル部１４のうち、上部パネル部１３側に小型のメインリール装置１００が設けられ、遊技者の視界に入りやすい中部パネル部１４側に演出表示装置としての大型のサブリール装置２００が設けられるので、遊技者の視覚に訴える演出表示を効果的に行うことができる。
【０１８３】
特に、新規な構造を有する小型のメインリール装置１００を設けたことにより、上部パネル部１３と中部パネル部１４とから成る前面パネル部におけるメインリール装置１００の占有領域を小さくすることができ、一方、サブリール装置２００や演出用ランプ１３ａ〜１３ｅ，１４ｂ，１４ｃ，１５ｂ，１５ｃ及びスピーカＱ１〜Ｑ４等その他の演出手段を設けるための領域（演出に係る領域）を相対的に拡大することができるため、遊技者により遊技を楽しんでもらうためのスロットマシン１０を提供することが可能となっている。
【０１８４】
つまり、図１に示したように、一般的な周知のスロットマシンと同程度の横幅ＷＡＡと縦幅ＴＡＡに決められている上部パネル部１３と中部パネル部１４とから成る前面パネル部において、メインリール装置１００の占有領域が極めて小さいので、演出に係る領域を相対的に大きくすることが可能である。
【０１８５】
なお、上述したように本実施形態における最適な場合として、各メインリールＭＲ１，ＭＲ２，ＭＲ３の直径Ｒを約１２０ｍｍ（具体的には１２２ｍｍ）とし、幅をリールテープＭＴＰ１，ＭＴＰ２，ＭＴＰ３の幅ＷＴと略同じ４４ｍｍ程度に設計することによって、メインリール装置１００の小型化を実現している。しかし、これは製品化のために具体的に決められた一つの最適条件であり、必ずしも各メインリールＭＲ１，ＭＲ２，ＭＲ３の直径Ｒと幅をこれら約１２０ｍｍと約４４ｍｍに決めなければならないというものではない。
【０１８６】
つまり、上述した式（１）（２）（３）（４−ａ）（４−ｂ）の条件を満足させるべく、各メインリールＭＲ１，ＭＲ２，ＭＲ３の直径Ｒを上記式（９）で示したように、約９５ｍｍ以上約１４０ｍｍ以下の範囲内に決めることが可能である。
【０１８７】
また、各メインリールＭＲ１，ＭＲ２，ＭＲ３の直径Ｒを約９５ｍｍ以上約１４０ｍｍ以下の範囲内に決める際、互いに隣接することとなる図柄の間に若干の隙間を生じさせて視認性の向上を図る点を考慮しつつ、上記式（８）で示したように、各リールテープＴＭＰ１，ＭＴＰ２，ＭＴＰ３の図柄数Ｋを、１２個以上、１５個以下に設定することが可能である。
【０１８８】
また、本実施形態では、図１に示したように、各メインリールＭＲ１，ＭＲ２，ＭＲ３に描かれている図柄を１個ずつ（別言すれば、１列分）目視できるように、第１透明窓ＷＤ１の縦幅が１図柄の縦幅とほぼ同程度に設計されているが、各メインリールＭＲ１，ＭＲ２，ＭＲ３に描かれている図柄を２個ずつ（別言すれば、２列分）目視できるように、第１透明窓ＷＤ１の縦幅を決めてもよい。そして、図１では有効ラインＬ１が１本であるが、横２列に並ぶ図柄の間隔（ピッチ間隔）ＰＰに合わせて、２本の有効ラインを設けるようにしてもよい。
【０１８９】
また、各メインリールＭＲ１，ＭＲ２，ＭＲ３の直径Ｒは、約９５ｍｍ以上約１４０ｍｍ以下となっているので、これらの直径Ｒに合わせて、第１透明窓ＷＤ１の縦幅も約９５ｍｍ以上約１４０ｍｍに決め、メインリールＭＲ１，ＭＲ２，ＭＲ３全体の回転動作が目視できるようにしてもよい。このように、メインリールＭＲ１，ＭＲ２，ＭＲ３全体の回転動作が目視できるように、第１透明窓ＷＤ１の縦幅を約１２０ｍｍに決めたとしても、メインリール装置１００自体がそもそも小型であるため、図１に示した横幅ＷＡＡと縦幅ＴＡＡに決められている上部パネル部１３と中部パネル部１４とから成る前面パネル部における、第１透明窓ＷＤ１の占有領域（表示領域）が小さくなり、演出表示装置等を設けるための演出に係る領域を相対的に大きくすることが可能である。
【０１９０】
つまり、各メインリールＭＲ１，ＭＲ２，ＭＲ３の直径Ｒを約９５ｍｍ以上、約１４０ｍｍ以下の範囲内の何れかの値に決めると共に、その何れかの直径Ｒに応じて各リールテープＴＭＰ１，ＭＴＰ２，ＭＴＰ３の図柄数Ｋを１２個以上、１５個以下の何れかの個数に決めることで、直径Ｒと図柄数Ｋとを変化させたメインリールＭＲ１，ＭＲ２，ＭＲ３を実現することができ、更に、図柄を目視可能にする第１透明窓ＷＤ１の上記縦幅を、１図柄分（１列分）から各メインリールＭＲ１，ＭＲ２，ＭＲ３の直径Ｒの範囲の何れかに決めることができる。このことから、様々な大きさで小型のメインリール装置１００を実現することができると共に、第１透明窓ＷＤ１の縦幅も様々な大きさにして、遊技者に対し遊技結果を提示することができる。また、スロットマシン全体のデザインを調整したり、設計の自由度を向上させることが可能である。
【０１９１】
また、本実施形態のメインリール装置１００は、３個のメインリールＭＲ１，ＭＲ２，ＭＲ３を備え、更に各メインリールＭＲ１，ＭＲ２，ＭＲ３の横幅がテープリールＭＴＰ１，ＭＴＰ，ＭＴＰ３の横幅ＷＴと同程度に設計されて、これらメインリールＭＲ１，ＭＲ２，ＭＲ３が接触しないように若干の間隔をおいて、リールケース本体１０１及びリールケースカバー１０２に収容されている。このことから、第１透明窓ＷＤ１の横幅も、これらメインリールＭＲ１，ＭＲ２，ＭＲ３を目視可能とするための幅に決められている。
【０１９２】
したがって、上述したようにテープリールＭＴＰ１，ＭＴＰ２，ＭＴＰ３の横幅ＷＴを約４４ｍｍとしたことで、メインリールＭＲ１，ＭＲ２，ＭＲ３全体の横幅を小さくし、且つ第１透明窓ＷＤ１の横幅も小さくすることができるため、前面パネル部における演出に係る領域を相対的に拡大することが可能である。
【０１９３】
更に又、本実施形態では、３個のメインリールＭＲ１，ＭＲ２，ＭＲ３を横一列に配置してメインリール装置１００が構成されているが、４個以上のメインリールを横一列に配置したメインリール装置を構成したとしても、前面パネル部における演出に係る領域を相対的に拡大することが可能となっている。つまり、４個以上のメインリールを横一列に配置すれば当然に、メインリール全体の横幅が大きくなるが、しかし、上述したように、各メインリールの直径Ｒが所定の条件を満足すべく小さいので縦幅がそもそも小さくなるため、前面パネル部における演出に係る領域を相対的に拡大することが可能である。
【０１９４】
更に又、各テープリール横幅ＷＴを４４ｍｍ以上にした場合でも、各メインリールの直径Ｒが所定の条件を満足すべく小さいので縦幅がそもそも小さくなるため、前面パネル部における演出に係る領域を相対的に拡大することが可能である。
【０１９５】
また、メインリール装置１００は、メインリールＭＲ１，ＭＲ２，ＭＲ３とステッピングモータＭＭ１，ＭＭ２，ＭＭ３を含めて全体的に小型であるため、図１に示したように、前面扉１１の裏面側に取り付けることができ、従来の大型のメインリールのように基体１２内に収容する必要がない。このことは、限られた容積に決められているスロットマシン１０内に、メインリール装置１００を自在に設けることが可能となることを意味することから、設計の自由度を向上させると共に、組み立て工程の簡素化、スロットマシン１００の内部構造の簡素化及び合理化等を実現することができる。そして、上述の内部構造の簡素化及び合理化等の実現によって空いたスペースに、例えば図２に示したように、大型のサブリール２００等の演出表示装置を収容することによって、従来のスロットマシンに較べて多様な演出表示を行って遊技者を楽しませることが可能である。
【０１９６】
ここで、本実施形態のスロットマシン１０において、メインリール装置１００の表示領域と演出のための演出領域とを次のように設定することが、遊技者に対する視認性の向上や、より効果的な演出を行って遊技者に楽しんでもらう等の観点から望ましい。
【０１９７】
すなわち、図１３に模式的に示すように、前面パネル部（上部パネル部１３と中部パネル部１４）と操作部１６及び下部パネル部１５とから成る全体のパネル部、すなわち遊技者に面することとなる「正面パネル部」の横幅ＷＡＡが約４７５ｍｍ、縦幅（高さ）ＴＡが約８１０ｍｍに決められているのに対し、メインリール装置１００に設けられているメインリールＭＲ１，ＭＲ２，ＭＲ３を視認可能にする第１透明窓ＷＤ１の横幅ＷＷＤ１を、３個のメインリールＭＲ１，ＭＲ２，ＭＲ３を同時に見ることができる幅に設定し、縦幅ＴＷＤ１を、約２５ｍｍ以上で各メインリールＭＲ１，ＭＲ２，ＭＲ３の直径Ｒ以下の範囲に設定することが好ましい。
【０１９８】
具体例として、各メインリールＭＲ１，ＭＲ２，ＭＲ３の横幅ＷＴを第１透明窓ＷＤ１の横幅ＷＷＤ１内に入るように設計し、第１透明窓ＷＤ１の横幅ＷＷＤ１を約１６０ｍｍ、縦幅をＴＷＤ１を約８０ｍｍ程度に設定すると、正面パネル部と第１透明窓ＷＤ１の表示領域との大きさを、視覚的に見て安定感のある比率にすることができる。
【０１９９】
このように、第１透明窓ＷＤ１の表示領域（横幅ＷＷＤ１と縦幅ＴＷＤ１）を決めると、遊技者はメインリールＭＲ１，ＭＲ２，ＭＲ３の外周面に描かれている図柄を少なくとも横一列分見ることができ、そして遊技結果を見ることが可能となる。更に、正面パネル部（横幅ＷＡＡと縦幅ＴＡ）における第１透明窓ＷＤ１の占有面積（ＷＷＤ１×ＴＷＤ１）を相対的に小さくし、演出表示を行うための占有面積を拡大することができるため、より効果的な演出表示を行うことができる。
【０２００】
また、第１透明窓ＷＤ１の表示領域（横幅ＷＷＤ１と縦幅ＴＷＤ１）を、演出表示を行うための主領域である「前面パネル部」の大きさ（横幅ＷＡＡと縦幅ＴＡＡ）との関係で決めてもよい。
【０２０１】
つまり、横幅ＷＡＡが約４７５ｍｍ、縦幅ＴＡＡが約４６２ｍｍの「前面パネル部」に対し、メインリール装置１００に設けられているメインリールＭＲ１，ＭＲ２，ＭＲ３を視認可能にする第１透明窓ＷＤ１の横幅ＷＷＤ１を、３個のメインリールＭＲ１，ＭＲ２，ＭＲ３を同時に見ることができる幅に設定し、縦幅ＴＷＤ１を、約２５ｍｍ以上で各メインリールＭＲ１，ＭＲ２，ＭＲ３の直径Ｒ以下の範囲に設定することが好ましい。
【０２０２】
具体例として、横幅ＷＡＡが約４７５ｍｍ、縦幅ＴＡＡが約４６２ｍｍの「前面パネル部」に対し、各メインリールＭＲ１，ＭＲ２，ＭＲ３の横幅ＷＴを第１透明窓ＷＤ１の横幅ＷＷＤ１内に入るように設計し、第１透明窓ＷＤ１の横幅ＷＷＤ１を約１６０ｍｍ、縦幅をＴＷＤ１を約８０ｍｍ程度に設定すると、前面パネル部と第１透明窓ＷＤ１の表示領域との大きさを、視覚的に見て安定感のある比率にすることができる。
【０２０３】
また、サブリール装置２００に設けられているサブリールＳＲ１，ＳＲ２，ＳＲ３を視認可能にする第２透明窓ＷＤ２の大きさと、上述の第１透明窓ＷＤ１の大きさとを、所定の面積比に基づいて決めてもよい。
【０２０４】
具体例として、上述した第１透明窓ＷＤ１の表示領域の面積（ＷＷＤ１×ＴＷＤ１）に対する、第２透明窓ＷＤ２の表示領域の面積（ＷＷＤ２×ＴＷＤ２）を、次式（１１）で表されるように、約５倍以上に設定すると、視覚的に見て安定感を発揮させ、効果的な演出表示を行う上で好ましい。
【０２０５】
【数１４】

【０２０６】
更に具体的に述べれば、第２透明窓ＷＤ２の横幅ＷＷＤ２を約３９０ｍｍ、縦幅ＴＷＤ２を約２１０ｍｍにし、それに合わせて、３個の各サブリールＳＲ１，ＳＲ２，ＳＲ３の直径を約２１０ｍｍ、夫々の横幅を約１２０ｍｍ、３個のサブリールＳＲ１，ＳＲ２，ＳＲ３の全体の横幅を約３９０ｍｍに設計し、一方、第１透明窓ＷＤ１の横幅ＷＷＤ１を約１６０ｍｍ、縦幅をＴＷＤ１を約８０ｍｍ程度に設定して、各メインリールＭＲ１，ＭＲ２，ＭＲ３の直径Ｒを上述の約１２０ｍｍ、メインリールＭＲ１，ＭＲ２，ＭＲ３の全体の横幅が第１透明窓ＷＤ１の横幅ＷＷＤ１（約１６０ｍｍ）に合うように、各メインリールＭＲ１，ＭＲ２，ＭＲ３の横幅ＷＴを決めると、視覚的に見て安定感のある比率にすることができる。
【０２０７】
なお、本実施形態のスロットマシン１０では、演出表示装置として大型のサブリール装置２００を設け、サブリールＳＲ１，ＳＲ２，ＳＲ３を適宜回転させることによって演出表示を行うこととしているが、他の演出表示装置を設けて演出を行ってもよい。
【０２０８】
例えば、図１に示した中部パネル部１４に対し配設されているサブリール装置２００の代わりに、第２透明窓ＷＤ２とほぼ同じ大きさの表示面を有するＣＲＴディスプレイや、平板型の２次元ＥＬ装置（カラー液晶ディスプレイ、有機ＥＬディスプレイ、多数の発光ダイオードが２次元配列されたドットマトリクス型のカラーＬＥＤディスプレイ等）を配設してもよい。
【０２０９】
また、かかるＣＲＴディスプレイや、平板型の２次元ＥＬ装置（カラー液晶ディスプレイ、有機ＥＬディスプレイ、多数の発光ダイオードが２次元配列されたドットマトリクス型のカラーＬＥＤディスプレイ等）を配設する場合にも、図１３を参照して説明した、第１透明窓ＷＤ１の表示領域の大きさ（横幅ＷＷＤ１とＴＷＤ１）に対する第２透明窓ＷＤ２の表示領域の大きさ（横幅ＷＷＤ２とＴＷＤ２）の条件を満足するように、各演出表示装置の表示面の大きさを決めることが望ましい。
【０２１０】
また、図１に示した中部パネル部１４のほぼ全体に、透過型液晶ディスプレイや透過型の有機ＥＬディスプレイを配置し、これらのディスプレイの裏面側（基体１２側）に大型のサブリール装置２００を設けて、これらのディスプレイで表示する画像とサブリール装置２００の動きとを組み合わせて演出表示を行うようにしてもよい。
【０２１１】
また、中部パネル部１４だけに限らず、上部パネル１３と中部パネル部１４のほぼ全体に、透過型液晶ディスプレイや透過型の有機ＥＬディスプレイを配置し、これらのディスプレイの裏面側（基体１２側）に大型のサブリール装置２００を設けて、これらのディスプレイで表示する画像とサブリール装置２００の動きとを組み合わせて演出表示を行うようにしてもよい。
【０２１２】
ただし、上部パネル１３と中部パネル部１４のほぼ全体に、透過型液晶ディスプレイや透過型の有機ＥＬディスプレイを配置する場合には、遊技結果を表示するメインリールＭＲ１，ＭＲ２，ＭＲ３の前面領域（上述の第１透明窓ＷＤ１に相当する領域）では、これらディスプレイによる画像を表示しないことが望ましい。別言すれば、１ゲームの間にメインリールＭＲ１，ＭＲ２，ＭＲ３が回転動作している間は、上述の前面領域においてこれらディスプレイによる画像を表示しないことが望ましい。
【０２１３】
また、図１及び図１３に示したように、メインリール装置１００と第１透明窓ＷＤ１を、演出表示装置としてのサブリール装置２００と第２透明窓ＷＤ２よりも上方、別言すれば前面パネル部の上方の部分に設けているが、これとは逆に、演出表示装置としてのサブリール装置２００と第２透明窓ＷＤ２よりも下方、別言すれば前面パネル部の下方の部分に、メインリール装置１００と第１透明窓ＷＤ１を設けるようにしてもよい。
【０２１４】
また、このように演出表示装置よりも下方にメインリール装置１００と第１透明窓ＷＤ１を設ける場合にも、図１３を参照して説明した、第１透明窓ＷＤ１の表示領域の大きさ（横幅ＷＷＤ１とＴＷＤ１）に対する第２透明窓ＷＤ２の表示領域の大きさ（横幅ＷＷＤ２とＴＷＤ２）の条件を満足するように、演出表示装置の表示面の大きさを決めることが望ましい。
【０２１５】
【発明の効果】
以上説明したように本発明の回胴式遊技機によれば、遊技結果を提示するための機能を有する小型のメインリール装置が前面パネル部若しくは正面パネル部に設けられるので、メインリールにおける表示領域に比して、演出に係る領域を相対的に拡大させることができ、この拡大された領域に演出表示装置を設けることによって、従来よりも多様な演出表示を行うことが可能な回胴式遊技機を提供することができる。

In addition to the basic configuration of the slot machine, an effect display device for providing an effect appealing to the eye is provided in order for the player to enjoy the game.
Here, a slot machine disclosed in Patent Document 1 is known as a slot machine formed by paying attention to the importance of the above-described effects.
[0004]
As shown in FIG. 1 and paragraphs [0023] to [0028] of the document 1, the slot machine (1) disclosed in this patent document 1 has a front door (2b) mounted on a housing (2a). Is pivotally supported, and the front door (2b) is provided with an upper decorative frame (4), a game panel (6), and a title panel (8), between the game panel (6) and the title panel (8). A so-called operation part provided with a medal insertion part (34), various operation buttons (35, 36a, 36b, 37, 40L, 40C, 40R), a start lever (38) and the like is provided on the protruding part.
[0005]
The upper decorative frame (4) is provided with openings (359L, 359C, 359R), and a small size as an effect display device is provided in the housing (2a) through these openings (359L, 359C, 359R). Reproduction reels (301L, 301C, 301R) (see FIGS. 13, 14, and 17 of Patent Document 1) are disposed so as to be visible.
[0006]
Further, a see-through window (14) is provided at the center of the game panel (6), and large reels (51L, 51C, 51R) are provided in the housing (2a) via the see-through window (14) (Patent Literature). 1 (see FIG. 17) is disposed so as to be visible.
[0007]
The large reels (51L, 51C, 51R) located at the center of the slot machine (1) are so-called main reels for presenting game results, and the start lever (38) is turned on. When the operation buttons (40L, 40C, 40R) are operated to stop in any order, the operation is stopped according to the order and the game result is given to the player. Present.
[0008]
That is, when the start lever (38) is turned on, a role lottery is performed, and each main reel (in which a symbol is drawn) is operated in response to the next stop operation of the operation buttons (40L, 40C, 40R). 51L, 51C, 51R) is stopped, and when the symbols of the main reels (51L, 51C, 51R) that have finally stopped are aligned on the active line in a predetermined combination, a prize is awarded. For example, a predetermined number of medals are awarded. It is to be paid out.
[0009]
Further, as described in paragraph [0128] of Patent Document 1, when the operation button (40L, 40C, 40R) is stopped, each main reel (51L, 51L, 51C, 51R) are controlled in order to stop them sequentially within 190 milliseconds.
[0010]
On the other hand, the production reels (301L, 301C, 301R) have large main reels (51L, 51C, 51R) in the center of the game panel (6) that follow the size of main reels that have been known for a long time. It is miniaturized because of the provided relationship.
[0011]
The small effect reels (301L, 301C, 301R) are operated independently of the large main reels (51L, 51C, 51R), and the above-mentioned game results are presented on the main reels (51L, 51C, 51R). On the other hand, in the effect reels (301L, 301C, 301R), various display operations are performed to display effects for the player to enjoy the game.

By the way, in the conventional slot machine, although the production reels (301L, 301C, 301R) are provided, paying attention to the importance of production, the production effect is sufficiently exhibited because of the small size. There is a problem that is not done.
[0014]
For example, as shown in FIG. 19 of Patent Document 1 above, the number of symbols on each effect reel (301L, 301C, 301R) is extremely small, about five, due to the downsizing, and the combination of symbols Since the number of patterns is reduced, there is a problem that the production has to be performed with poor expressive power.
[0015]
In addition, in order to increase the number of symbols of the effect reels (301L, 301C, 301R) and the number of symbols combined, the visibility is reduced simply by reducing the symbols of the effect reels (301L, 301C, 301R). As a result, there arises a problem that it is difficult to produce a highly visual effect.
[0016]
In addition, it is possible to increase the number of symbols by increasing the production reels (301L, 301C, 301R), but in correspondence with the upper decorative frame (4) and the game panel (6) with a limited occupation area, It is difficult to arrange the large production reels (301L, 301C, 301R) in the casing (2a) together with the large main reels (51L, 51C, 51R).
[0017]
In other words, since the above-mentioned front door (2b) and the housing (2a) facing the player are necessarily limited in size, they are both large production reels (301L, 301C, 301R) and main reels. Even if it is attempted to provide (51L, 51C, 51R), there is a problem that in reality it is difficult to realize.
[0018]
The present invention has been made in view of such conventional problems, and includes a main reel device for presenting a game result and an effect display device for effect display, and a structure that can enhance the effect of effect display by the effect display device.

Thus, the first annular portion 109 is provided concentrically from the center of the base portion 107. The plurality of bridge portions 111 provided in the first annular portion 109 are oriented in a direction perpendicular to the extending direction of the arm portion 108, and all have the same length (the width WT of the reel tape MTP1). And a second annular part 110 having the same diameter as the first annular part 109 is formed at the tip of these bridge parts 111.
[0094]
Therefore, the first annular portion 109 is supported by a plurality of arm portions 108 extending from the base portion 107, and the second annular portion 110 is formed by the bridge portion 111 formed on the first annular portion 109. The first and second annular portions 109 and 110 are supported by each other at a constant interval (substantially the same interval as the width WT of the reel tape MTP1).
[0095]
Then, the reel tape MTP1 formed of a long plastic sheet on which a plurality of symbols shown in FIG. 8 are printed is mounted on the outer periphery of the first and second annular portions 109 and 110, An outer peripheral surface of the main reel MR1 is formed.
[0096]
Further, a female screw portion 104a is formed at the center of the rotating shaft 104, and through holes 105b and 107a aligned with the female screw portion 104a are also formed at the central portions of the relay shaft 105 and the base 107, respectively. The relay shaft 105, the relay member 106, and the base 107 are fixed to the rotating shaft 104 of the stepping motor MM1 by screwing and tightening the male screw 112 to the female screw portion 104a through the through holes 107a and 105b. Thus, the main reel MR1 is rotated by receiving the driving force of the stepping motor MM1.
[0097]
Although not shown, the stepping motor MM1 incorporates an optical rotary encoder that detects the rotation angle of the rotation shaft 104 with respect to a predetermined reference angle. By controlling the stepping motor MM1 while comparing the angle detection signal output from the control signal supplied from the main control board 700, the rotation of the stepping motor MM1 is controlled according to the control signal supplied from the main control board 700. Control of braking and stopping is performed, and accordingly, rotation of the main reel MR1 and control of braking and stopping are appropriately performed.
[0098]
Thus, the main reel MR1 has a cylindrical shape and is reduced in weight by mounting the reel tape MTP1 on a skeleton formed of lightweight plastic, and gives a large load to the stepping motor MM1. There is no such thing.
[0099]
Further, when the base 107 is fixed to the rotating shaft 104, the main reel MR1 is disposed so as to contain the stepping motor MM1, so that a unit structure having a small thickness in the axial direction of the rotating shaft 104 is realized.
[0100]
The second main reel unit having the main reel MR2 and the stepping motor MM2 assembled to the support plate MS2, and the third main reel unit having the main reel MR3 and the stepping motor MM3 assembled to the support plate MS3 are also described above. It has the same basic structure as the first main reel unit. The main reel MR2 is equipped with a tape reel MTP2 shown in FIG. 8, and the main reel MR3 is equipped with a tape reel MTP3. The widths of the tape reels MTP2 and MTP3 are also equal to the width WT of the tape reel MTP1.
[0101]
In addition, as shown in FIG. 8, the tape reels MTP1, MTP2, and MTP3 are combined with five kinds of symbols of "watermelon", "grape", "lemon", "peach", and "eggplant", respectively. It is drawn one by one.
[0102]
Furthermore, the main reel device 100 of the present embodiment is designed based on the following conditions for the sizes of the main reels MR1, MR2, MR3 and the sizes of symbols drawn on the reel tapes MTP1, MTP2, MTP3. By doing so, it is miniaturized.
[0103]
First, as represented by the following formulas (1) and (2), the number of revolutions N when the main reels MR1, MR2, MR3 are rotated at a constant speed in response to the start lever BL being turned on is set to The time from the time when the stop button BP1, BP2, BP3 is further stopped to the time when each main reel MR1, MR2, MR3 rotating at the above-mentioned rotation speed N is stopped is set to 80 rpm or less. Τ) (referred to as “stop time”) is determined within 190 milliseconds.
[0104]
[Expression 1]

[Expression 2]

Further, the main control board 700 performs a so-called role lottery in response to the start lever BL being turned on, and under the control of the main control board 700 in response to the stop buttons BP1, BP2, BP3 being operated to stop. The spinning device substrate 900 stops each of the main reels MR1, MR2, MR3 within the stop time τ. During this stop time τ, the symbols drawn on the main reels MR1, MR2, MR3 are maximized. The three symbols corresponding to the above-mentioned lottery combination are aligned on the effective line L1 of the first transparent window WD1 by stopping by shifting by three frames.
[0105]
That is, for example, if the combination of symbols corresponding to the above-mentioned lottery combination is “watermelon”-“grape”-“lemon” in the order of the main reels MR1, MR2, MR3, the stop button BP1 is stopped. By rotating the main reel MR1 by a maximum of three symbols (a maximum of three frames) within the stop time τ from the time point, the symbol “watermelon” is aligned on the effective line L1 during the rotation. Further, by rotating the main reel MR2 by a maximum of three symbols within the stop time τ from the time when the stop button BP2 is stopped, the symbols “grape” are aligned on the effective line L1 during the rotation. It is said. Further, by rotating the main reel MR3 by a maximum of three symbols within the stop time τ from the time when the stop button BP3 is stopped, the symbols “lemon” are aligned on the effective line L1 during the rotation. It is said.
[0106]
In this way, by stopping the symbols after shifting them by a maximum of three frames during each stop time τ including the symbols at the time when the stop buttons BP1, BP2, BP3 are stopped, We try to stop it so as not to give it a sense of incongruity.
[0107]
In addition, when the stop buttons BP1, BP2, BP3 are stopped, for example, the above three symbols “watermelon”-“grape”-“lemon” are all on the effective line L1 of the first transparent window WD1. Is stochastically rare, but while the main reels MR1, MR2, MR3 are shifted by up to 3 frames, the three patterns "Watermelon"-"Grape"-"Lemon" are aligned on the effective line L1. I am trying to do it.
[0108]
The number of symbols (number of frames) to be shifted when stopping each of the main reels MR1, MR2, MR3 will be referred to as a control frame number Nz and will be described below. In the present embodiment, the control frame number Nz is set as described above. As shown in the following formula (3), a maximum of three is determined.
[0109]
[Equation 3]

[0110]
That is, Nz ≦ 3 means that the maximum number of control frames Nz is allowed, and when the stop operation is performed, the symbol to be stopped (the symbol corresponding to the lottery role) is an effective line. When it comes to L1, each main reel MR1, MR2, MR3 is stopped at that time. On the other hand, when the symbol to be stopped does not come on the effective line L1 when the stop operation is performed, When the main reels MR1, MR2, MR3 are rotated by one symbol or two symbols during the stop time τ, and the symbol to be stopped thereby comes on the effective line L1, each main reel MR1 , MR2 and MR3 are stopped.
[0111]
In order to improve visibility for the player, the size of each symbol drawn on each of the tape reels MTP1, MTP2, and MTP3, that is, the size of the vertical width H and the horizontal width W is expressed by the following equation (4-a). As shown in (4-b), they are determined to be 25 mm or more and 35 mm or more, respectively.
[0112]
[Expression 4]

[0113]
In order to satisfy the conditions of the above formulas (1), (2), (3), (4-a), and (4-b), the diameters R of the main reels MR1, MR2, and MR3 and the tape reels MTP1, MTP2 , The number K of symbols drawn on MTP3 and the size of each symbol (vertical width H and horizontal width W) were optimized.
[0114]
First, when the relationship among the rotational speed N, the stop time τ, the control frame number Nz, and the number K of symbols shown in the above formulas (1), (2) and (3) is obtained, the following formula (5) is obtained.
[0115]
[Equation 5]

[0116]
Here, when controlling the stepping motors MM1, MM2, MM3, the most severe condition is the case where the rotational speed N is 80 rpm, and the stop time τ at which the main reels MR1, MR2, MR3 can be stopped most stably. Is 190 msec, so substituting these values into the above equation (5) gives
[Formula 6]

It becomes. When the number K of symbols is obtained based on the relational expression (6), a value of 11.84 is obtained as shown in the following equation (7). Therefore, the number K of symbols is 12 or more. The result is that it is desirable.
[0117]
[Expression 7]

[0118]
Therefore, when the above equation (6) is applied again to determine the number of control frames Nz when the number K is 11, 12, 13, 14, 15,...
[Equation 8]

It becomes.
[0119]
Here, since the number of control frames Nz when K = 11 is less than 3, the condition of the above expression (3) is not sufficiently satisfied, and K = 12, K = 13, K = 14, and so on. , The number of control frames Nz when K = 15 is approximately 3, so that the condition of the above equation (3) is satisfied, and the number of control frames Nz when K = 16 is 4, so that the above equation (3) is satisfied. The conclusion that the above condition is not satisfied was derived, and the suitable number K of symbols was determined to be any natural number of 12 or more and 15 or less as shown by the following equation (8).
[0120]
[Equation 9]

Next, among the number K of symbols represented by the above formula (8), the optimum number K was determined based on the following analysis.
[0121]
First, in order to realize a small main reel device 100 that can satisfy the above-described conditions, the circumference C and the diameter R of each main reel MR1, MR2, MR3 are determined according to the condition of the above equation (8), and one pattern is obtained. Since the minimum vertical width H is 25 mm,
[0122]
[Expression 10]

The relationship is obtained.
[0123]
Therefore, in consideration of the manufacturing accuracy for manufacturing the main reels MR1, MR2, MR3, the minimum diameter R is about 95 mm as shown in the following formula (9), which is not redundant (too large). The conclusion that the diameter R is about 120 mm was obtained.
[0124]
[Expression 11]

[0125]
However, if the symbols are drawn on the reel tapes MTP1, MTP2, and MTP3 based on the value of the diameter R expressed by the above equation (9), it is difficult to see the symbols adjacent to each other. That is, since there is almost no gap between the symbols, it becomes extremely difficult to see and it is difficult to distinguish the symbols adjacent to each other.
[0126]
Therefore, the least common multiple diameter R of 120 mm is determined as an optimal value candidate, and the pitch interval PP of each symbol when the number of symbols K is 12, 13, 14, and 15 is obtained. When,
[Expression 12]

It becomes.
[0127]
Here, when the number K of symbols is 12, it is possible to increase the symbol and further increase the gap between adjacent symbols, but this results in a redundant reel structure. Further, when the number K of symbols is set to 15, there is a problem that it becomes difficult to distinguish because there is no gap between the symbols adjacent to each other.
[0128]
On the other hand, when the number K of symbols is 13 or 14, the vertical width H and the gap of each symbol in the symbol pitch interval PP can be set relatively freely, and the symbols can be made easier to see. it can.
[0129]
Therefore, when the number K of symbols is 15, a gap of about 3 mm is generated between the symbols, and the main reels MR1, MR2, MR2 are considered in consideration of the demand for miniaturization of the main reels MR1, MR2, MR3. The diameter R of MR3 is determined to be 140 mm, and the length L of each reel tape MTP1, MTP2, MTP3 is determined to be about 440 mm to match the circumference C of each main reel MR1, MR2, MR3. Therefore, when the optimum case and the preferred case are included, it is concluded that the diameter R of each main reel MR1, MR2, MR3 should be in the range of about 95 mm to about 140 mm as shown in the following formula (10). .
[0130]
[Formula 13]

[0131]
Further, as an optimum case of the present embodiment, the diameter R of each main reel MR1, MR2, MR3 is determined to be about 120 mm (more specifically, 122 mm), and the number K of symbols is designed rather than 14 pieces. By determining the number of 13 that can increase the degree of freedom of the above, the conditions of the above formulas (1), (2), (3), (4-a), and (4-b) are satisfied, and there is a gap between the symbols. Realized the optimum reel structure.
[0132]
In the optimum case, the vertical width H of one symbol is 26 mm, the horizontal width W is 35 mm, and a gap is created between symbols that are adjacent to each other, thereby improving visibility.
[0133]
As described above, when the specifications of the most preferable main reel device 100 of the present embodiment are listed,
[1] The number of revolutions of the main reels MR1 to MR3 during constant speed rotation is N ≦ 80 rpm.
[2] Each stop time of the main reels MR1 to MR3 is set to τ ≦ 190 msec.
[3] The diameter of the main reels MR1 to MR3 is R = 122 mm.
[4] The circumference of the main reels MR1 to MR3 is C = 383 mm.
[5] The number of symbols on the main reels MR1 to MR3 is K = 13
[6] Number of control frames, Nz ≦ 3
[7] Five types of symbols based on the number of control frames Nz
[8] The vertical width of one pattern is H = 26mm, and the horizontal width is W = 35mm.
[9] The pitch interval of the pattern is PP = 29.5 mm.
[10] Reel tapes MTP1 to MTP3 have a length L = 383 mm and a width WT = 44 mm
[11] The number of control steps per rotation of the stepping motors MM1 to MM3 is 400 steps, and the rotation angle per symbol is controlled in 30 steps or 31 steps.
[0134]
By reducing the size of the reel case body 101 and the reel case cover 102 so as to be large enough to accommodate the first to third main reel units, the overall size of the main body can be reduced. The reel device 100 was realized.
[0135]
As described above, the main reel device 100 according to this embodiment includes the above-described optimized small main reels MR1, MR2, and MR3, so that the visibility and controllability are good and the miniaturization is realized. .
[0136]
Next, the structure of the sub reel device 200 as an effect display device will be described with reference to FIGS. 9 is a perspective view showing the external structure of the sub-reel device 200, and FIG. 10 is a development view showing the tape reels STP1, STP2, and STP3 mounted on the outer periphery of the sub-reels SR1, SR2, and SR3. .
[0137]
In FIG. 9, the sub-reel device 200 has three cylindrical sub-reels SR1, SR2, SR3 accommodated in a rectangular support case 201 formed of hard plastic, and is arranged on the outer periphery of each sub-reel SR1, SR2, SR3. , Tape reels STP1, STP2, and STP3 shown in FIG. 10 are mounted.
[0138]
Basically, by the same unit structure as the main reel device 100 described above, a stepping motor (reference numeral omitted) for rotationally driving the sub reel SR1, a stepping motor (reference numeral omitted) for rotating the sub reel SR2, and a sub reel SR3 Further, although omitted in FIG. 9, a drive circuit board 600 for driving each of the above stepping motors is attached to the upper end of the support case 201.
[0139]
Here, each of the sub reels SR1, SR2, SR3 is designed to have a diameter of about 230 mm and a width of about 80 mm, and on each outer peripheral surface there is a design larger than the design depicted on the main reels MR1, MR2, MR3. 21 pieces are drawn.
[0140]
Further, the three sub reels SR1, SR2, SR3 are provided in a horizontal row along the rotation axis direction without contacting each other, so that the pitch interval in the horizontal direction of each sub reel SR1, SR2, SR3 is about 90 mm. The overall width of the three sub reels SR1, SR2, SR3 is designed to be about 270 mm.
[0141]
Then, according to the control signal supplied from the main control board 700 according to the progress of the game, the drive circuit board 600 supplies the drive power subjected to the pulse width control to each of the stepping motors SM1, SM2, and SM3, so that each stepping By causing the motors SM1, SM2, and SM3 to rotate forward, reverse, and stop, the movements of the sub reels SR1, SR2, and SR3 are variously changed, and the movement of the symbols is changed accordingly, thereby effect display is performed.
[0142]
Next, a control system provided in the slot machine 10 will be described with reference to the block diagram of FIG.
[0143]

Each of them is connected by wiring cables. In addition, the drive circuit 600 is connected to the sub-control board 300 by wiring.
[0144]
The main control board 700 is equipped with a semiconductor memory ROM and a microprocessor MPU. The microprocessor MPU executes a system program and a slot machine game program stored in advance in the semiconductor memory ROM. The entire slot machine 10 is centrally controlled by giving predetermined commands to 900, 300, 400, 500, and 800 to perform distributed control.
[0145]
Stepping motors MM1, MM2, and MM3 for rotating the main reels MR1, MR2, and MR3 are connected to the spinning device substrate 900. When a control signal indicating that the main reels MR1, MR2, MR3 should be rotated or stopped is supplied from the main control board 700, the rotator apparatus board 900 controls the power supply to the stepping motors MM1, MM2, MM3. The operation of the main reels MR1, MR2, MR3 is controlled.
[0146]
In other words, when a control signal indicating the start of rotation is supplied from the main control board 700, the spinning device board 900 starts the stepping motors MM1, MM2, and MM3, and sets the main reels MR1, MR2, and MR3 to 80 rpm or less. Control to rotate at speed.
[0147]
In addition, when a control signal for stopping the main reel MR1 is supplied from the main control board 700, the spinning device board 900 performs braking control on the stepping motor MM1, and stops the main reel MR1 within the stop time τ, that is, within 190 msec. Let Further, when a design to be stopped is specified on the effective line L1 and a control signal is supplied, the spinning device substrate 900 rotates the main reel MR1 by the number of control frames Nz within the stop time τ, and the specified When the symbols are aligned on the effective line L1, the main reel MR1 is stopped.
[0148]
Further, when a control signal for stopping the main reel MR2 is supplied from the main control board 700, the stepping motor MM2 is braked and the main reel MR1 is stopped within the stop time τ. When a symbol to be stopped is designated on the effective line L1 and a control signal is supplied, the main reel MR2 is rotated by the number of control frames Nz within the stop time τ, and the designated symbol is placed on the effective line L1. When they are aligned, the main reel MR2 is stopped.
[0149]
Further, when a control signal for stopping the main reel MR3 is supplied from the main control board 700, the stepping motor MM3 is braked and the main reel MR3 is stopped within the stop time τ. When a symbol to be stopped is specified on the effective line L1 and a control signal is supplied, the main reel MR3 is rotated by the number of control frames Nz within the stop time τ, and the specified symbol is on the effective line L1. When they are aligned, the main reel MR3 is stopped.
[0150]
When the sub control board 300 is connected to the effect lamps 13a to 13e, 14b, 14c, 15b, and 15c and the speakers Q1 to Q4, and the control signal that suggests the start of the effect is supplied from the main control board 700, the effect is displayed. The lamps 13a to 13e, 14b, 14c, 15b, and 15c and the speakers Q1 to Q4 are driven to produce an effect appealing to the player's vision and hearing. In addition, the main control board 700 commands a lottery role, and the sub-control board 300 provides effects corresponding to the commanded role lamps 13a-13e, 14b, 14c, 15b, 15c and speakers Q1-Q4. By doing this, an effective presentation that interests the player is performed.
[0151]
Further, when the control signal suggesting the start of the production is supplied from the main control board 700, the sub control board 300 instructs the drive circuit board 600 to start the stepping motors SM1, SM2, SM3 of the sub reel device 200. The effect display is performed by rotating the sub reels SR1, SR2, SR3. Further, when a lottery role is instructed from the main control board 700, the sub control board 300 instructs the drive circuit board 600 to start the stepping motors SM1, SM2, SM3, and an effect corresponding to the instructed role. Is performed by the sub reels SR1, SR2, SR3.
[0152]
The central display board 400 is connected to the bet buttons BT1 and BT2, the start lever BL and the stop buttons BP1, BP2 and BP3, and controls the output signals output from these switches BT1, BT2, BL, BP1, BP2 and BP3. It functions as a relay board that transfers to the board 700. In addition, the central display board 400 transfers an output signal output from the game medal detection sensor provided in the selection mechanism G0 to the main control board 700 to inform the medal insertion part MD of the number of medals and To inform you of the clogging and clogging.
[0153]
The main control board 700 detects the number of bets per game when the bet buttons BT1 and BT2 are turned on, and detects that a game start instruction is issued when the start lever BL is turned on. When the stop buttons BP1, BP2, BP3 are stopped in an arbitrary order, it is detected that an instruction to stop the main reels MR1, MR2, MR3 is issued in that order.
[0154]
Here, when the main control board 700 detects that the above-mentioned start lever BL is turned on, a command for lottery apparatus board 900 to rotate the above-mentioned main reels MR1, MR2, MR3 is performed after performing the role lottery. At the same time, the sub-control board 300 is commanded to cause the effect lamps 13a to 13e, 14b, 14c, 15b, and 15c, the speakers Q1 to Q4, and the sub reel device 200 to perform effects.
[0155]
When the stop buttons BP1, BP2, and BP3 are stopped in any order, the main control board 700 stops the main reels MR1, MR2, and MR3 in the order of the stop operations, and lottery is performed as described above. A command is sent to the spinning device substrate 900 to align the symbols corresponding to the roles on the effective line L1. In addition, the main control board 700 instructs the sub control board 300, and each time the stop buttons BP1, BP2, BP3 are stopped, the effect lamps 13a to 13e, 14b, 14c, 15b, 15c and the speaker Q1 are displayed. The game progress status and the like are notified to the player by variously changing the production by ~ Q4 and the sub reel device 200.
[0156]
The power supply substrate 500 is formed with a power distribution circuit that distributes various power supply voltages generated by the power supply device PWU to the hopper device HP and other places, and supplies system power necessary for the operation of the slot machine 100 from the power distribution circuit. To do.
[0157]
When the power supply device board 500 receives a command to pay out game medals from the main control board 700, it controls the hopper device HP to pay out game medals.
[0158]
The external concentrated terminal board 800 sends a signal indicating the progress of the game in the slot machine 10 output from the main control board 700 to the hall computer described above.
[0159]
Next, the operation of the slot machine 10 will be described with reference to FIG.
[0160]
FIG. 12 (a) relates the types of combinations provided in the slot machine 10, the combinations of symbols corresponding to each combination, the number of game medals to be paid out when winning each combination, and the like. FIG. 12B is a schematic diagram showing the principle of the role lottery.
[0161]
In FIG. 12A, the slot machine 10 includes a special combination called a single bonus (SB), a re-playing combination called replay, two small combinations, that is, a small combination <1> and a small combination <2>. Is provided.
[0162]
In the single bonus (SB), the player operates the bet button BT1 (or BT2), the start lever BL, and the stop buttons BP1, BP2, and BP3 to play one game. As a result, the main reels MR1 and MR2 shown in FIG. When the symbols drawn on the outer peripheral surface of MR3 are stopped on the effective line L1 (see FIG. 1) of the first transparent window WD1 in a combination of “watermelon”-“peach”-“peach”, This is a function of paying out 13 game medals to the player (that is, 13 times the number of bets) and providing a privilege that allows the player to advance the game in an advantageous manner.
[0163]
In the replay, the player operates the bet button BT1 (or BT2), the start lever BL, and the stop buttons BP1, BP2, and BP3 to play one game. As a result, the outer peripheries of the main reels MR1, MR2, and MR3 shown in FIG. When the symbols drawn on the surface are all aligned on the effective line L1 of the first transparent window WD1 with the combination of “grape”-“grape”-“peach”, the game medals are not paid, but the game It is a role that gives the player a privilege to play the game again without presenting the number of bets.
[0164]
As for the small role <1>, the player operates the bet button BT1 (or BT2), the start lever BL, and the stop buttons BP1, BP2, BP3 to play one game. As a result, the main reels MR1, MR2 shown in FIG. When the symbols drawn on the outer peripheral surface of MR3 are stopped on the effective line L1 of the first transparent window WD1 with a combination of "watermelon"-"grape"-"lemon", 13 sheets (that is, bet It is a role of paying game medals of 13 times the number.
[0165]
As for the small role <2>, the player operates the bet button BT1 (or BT2), the start lever BL, and the stop buttons BP1, BP2, and BP3 to play one game. As a result, the outer periphery of the main reel MR1 shown in FIG. When the symbols of “peach” drawn on the surface are aligned and stopped on the active line L1 of the first transparent window WD1, three game medals are paid (that is, three times the bet number). That is, the small role <2> wins only by aligning the “peach” symbol of the main reel MR1 on the effective line L1 of the first transparent window WD1, regardless of the symbols of the remaining main reels MR2 and MR3. This is the role of paying three game medals (three times the number of bets).
[0166]
When the player turns on the bet button BT1 (or BT2) to present the number of bets per game and turns on the start lever BL, the main control board 700 starts control of one game and performs a lottery drawing. Do.
[0167]
In this role lottery, first, the microprocessor MPU in the main control board 700 performs random number calculation, whereby 1 in the range of the minimum random value 0 to the maximum random value ηmax (65535 in this embodiment). Two random values ηi are generated internally.
[0168]
Then, as shown in FIG. 12B, the single bonus (SB), the replay, the small combination <1>, and the small combination <2> have a predetermined random number value within the minimum random number value 0 to the maximum random number value ηmax. The microprocessor MPU is assigned in advance in association with the range, and the microprocessor MPU determines the coincidence by comparing the internally generated random value ηi with the range of each assigned random value, thereby determining the singleness. One of the bonus (SB), replay, small role <1>, and small role <2> is drawn. If the internally generated random value ηi does not correspond to any of the random numbers of the single bonus (SB), the replay, the small role <1>, and the small role <2>, the microprocessor MPU Lottery.
[0169]
For example, the microprocessor MPU draws the small role <2> when the internally generated random value ηi satisfies the relationship 0 ≦ ηi <η1 shown in FIG. 12B, and satisfies the relationship η1 ≦ ηi <η2. If a relationship of η2 ≦ ηi <η3 is satisfied, a replay (re-playing player) is selected, and if a relationship of η3 ≦ ηi <η4 is satisfied, a single bonus (SB) is selected, and η4 ≦ When the relationship of ηi <ηmax is satisfied, other combinations or loses are drawn.
[0170]
The range of random values corresponding to the loss is the largest, and then the range of random values gradually decreases in the order of small role <2>, small role <1>, replay (re-playing role), and single bonus (SB). By being determined in advance, the lottery probability of losing is the highest, and the lottery probability of the single bonus (SB) is the lowest.
[0171]
Further, the main control board 700 performs a lottery drawing, commands the spinning device board 900 to rotate the main reels MR1, MR2, MR3 at a predetermined speed of 80 rpm or less, and further instructs the sub control board 300 to execute the sub reels. While rotating SR1, SR2, SR3 and driving the effect lamps 13a-13e, 14b, 14c, 15b, 15c and the speakers Q1-Q4, an effect appealing to sight and hearing is started.
[0172]
Next, when the player performs stop operations on the stop buttons BP1, BP2, BP3 in an arbitrary order, the main control board 700 instructs the spinning device board 900 to stop the main reels MR1, MR2, MR3 as described above. In addition, the sub-control board 300 is instructed to change the rotation of the sub-reels SR1, SR2, and SR3, and the lighting lamps 13a to 13e, 14b, 14c, 15b, and 15c are turned on and blinking, and the speaker. By changing the sound effects of Q1 to Q4, an effect appealing to the sight and hearing corresponding to the stop operation of the player is performed.
[0173]
Here, when the main control board 700 has drawn the single bonus (SB) in the above-mentioned role lottery, the spinning device board 900 is drawn on the outer peripheral surface of each main reel MR1, MR2, MR3. Stepping motors MM1, MM2, and MM3 are braked and controlled in the order of stop operation in order to align the symbols on the effective line L1 of the first transparent window WD1 with a combination of “watermelon”-“peach”-“peach”, respectively. Is stopped within the stop time τ (that is, 190 msec).
[0174]
That is, the spinning device substrate 900 satisfies the condition of the number of control frames Nz within the stop time τ, and the symbols drawn on the outer peripheral surfaces of the main reels MR1, MR2, MR3 are “watermelon”-“peach”. ”-“ Peach ”is combined to stop on the effective line L1.
[0175]
Here, when the main reel MR1 is rotating, for example, the “grape” symbol (designated by the symbol t1) drawn at the bottom of the tape reel MTP1 shown in FIG. 8 is the first transparent window WD1. If the player stops the stop button SP1 when positioned on the effective line L1, the spinning device substrate 900 has the control frame number Nz set to 3 (Nz ≦ 3). The reel MR1 is rotated by up to three frames, and when the “watermelon” symbol of the main reel MR1 is positioned on the effective line L1 during the rotation, the stepping motor MM1 and the main reel MR1 are stopped at that time. In other words, when the “watermelon” symbol indicated by the symbol t2 in FIG. 8 is positioned on the effective line L1, the stepping motor MM1 and the main reel MR1 are stopped at that time, thereby corresponding to the winning combination. The "watermelon" symbol to be stopped is accurately stopped on the effective line L1.
[0176]
Further, when the main reel MR1 is rotating and, for example, the “watermelon” symbol indicated by reference numeral t2 in FIG. 8 is positioned on the effective line L1 of the first transparent window WD1, the player presses the stop button SP1. If the stop operation is performed, the spinning device substrate 900 stops the main reel MR1 at the time t2 when the stop operation is performed. In addition, when the “watermelon” symbol indicated by reference sign t2 is almost separated from the effective line L1 of the first transparent window WD1, the number of control frames Nz is set to 3 (Nz ≦ 3). Therefore, the main reel MR1 is rotated by up to three frames, and the stepping motor MM1 and the main reel MR1 are stopped when the “watermelon” symbol indicated by reference numeral t3 is positioned on the effective line L1. Then, the symbol of “watermelon” corresponding to the winning combination is accurately stopped on the effective line L1.
[0177]
Similarly, since the spinning device substrate 900 has the control frame number Nz set to 3 (Nz ≦ 3), the main reel MR1 is rotated by up to 3 frames from the time when the stop operation is performed, and the rotation is performed. When the “watermelon” symbol of the main reel MR1 is positioned on the effective line L1, the stepping motor MM1 and the main reel MR1 are stopped at that time, so that the single bonus (SB) that is drawn in a lottery is almost certainly obtained. The corresponding “watermelon” symbol is positioned on the effective line L1, and the stepping motor MM1 and the main reel MR1 are stopped.
[0178]
Further, even when any of the other small roles <1>, small roles <2>, and replays (replays) is drawn, the spinning device substrate 900 is similar to the case of the single bonus (SB) role. When the stepping motor MM1 is brake controlled while satisfying the conditions of the control frame number Nz and the stop time τ, the symbols corresponding to those roles (when the lottery role is the small role <1>) are almost certainly Is placed on the effective line L1 to stop the stepping motor MM1 and the main reel MR1.
[0179]
In addition, when the stop buttons SP2 and SP3 are stopped, the spinning device substrate 900 satisfies the conditions of the number of control frames Nz and the stop time τ as in the case where the stop button SP1 is stopped. However, by controlling the stepping motors MM2 and MM3 for braking, the symbol corresponding to the winning combination is positioned on the effective line L1, and the stepping motors MM2 and MM3 and the main reels MR2 and MR3 are stopped. Let
[0180]
The main control board 700 stops when the three symbols of the main reels MR1, MR2, and MR3 are aligned on the effective line L1 in a combination corresponding to the lottery combination as shown in FIG. When it is determined that the winning is confirmed, the power supply device substrate 500 is instructed to pay out a predetermined number of game medals.
[0181]
Further, the main control board 700 instructs the sub control board 300 to perform an effect for notifying the winning decision, and then completes the control for one game, and the player starts the next game. Wait until When the start lever BL or the like is turned on, the progress of the next game is controlled.
[0182]
As described above, according to the slot machine 10 of the present embodiment, the small main reel device 100 is provided on the upper panel portion 13 side among the upper panel portion 13 and the middle panel portion 14 that are provided for performing an effect. Since the large sub-reel device 200 as an effect display device is provided on the side of the middle panel portion 14 that is easy to enter the player's field of view, an effect display appealing to the player's vision can be effectively performed.
[0183]
In particular, by providing the small main reel device 100 having a novel structure, the area occupied by the main reel device 100 in the front panel portion including the upper panel portion 13 and the middle panel portion 14 can be reduced. Because the sub reel device 200, the effect lamps 13a to 13e, 14b, 14c, 15b and 15c, and other effect means such as the speakers Q1 to Q4 can be relatively enlarged. It is possible to provide the slot machine 10 for the player to enjoy the game.
[0184]
That is, as shown in FIG. 1, in the front panel portion including the upper panel portion 13 and the middle panel portion 14 which are determined to have the same width WAA and height TAA as those of a general known slot machine, Since the area occupied by the reel device 100 is extremely small, it is possible to relatively increase the area related to the effect.
[0185]
As described above, as an optimal case in the present embodiment, the diameter R of each main reel MR1, MR2, MR3 is about 120 mm (specifically 122 mm), and the width is the width WT of the reel tapes MTP1, MTP2, MTP3. The main reel device 100 can be downsized by designing it to approximately 44 mm, which is approximately the same as the above. However, this is one optimum condition specifically determined for commercialization, and the diameter R and width of each main reel MR1, MR2, MR3 must be determined to be about 120 mm and about 44 mm. is not.
[0186]
That is, the diameter R of each main reel MR1, MR2, MR3 is expressed by the above equation (9) in order to satisfy the conditions of the above equations (1), (2), (3), (4-a), and (4-b). As described above, it can be determined within a range of about 95 mm or more and about 140 mm or less.
[0187]
Further, when determining the diameter R of each main reel MR1, MR2, MR3 within the range of about 95 mm to about 140 mm, a slight gap is generated between the symbols adjacent to each other to improve the visibility. Considering this point, as shown in the above equation (8), the number K of symbols of each reel tape TMP1, MTP2, MTP3 can be set to 12 or more and 15 or less.
[0188]
Further, in the present embodiment, as shown in FIG. 1, the first symbols are drawn on the main reels MR1, MR2, MR3 so that one symbol (in other words, one row) can be visually observed. The vertical width of the transparent window WD1 is designed to be approximately the same as the vertical width of one symbol. However, two symbols (in other words, two columns) are drawn on each main reel MR1, MR2, MR3. ) The vertical width of the first transparent window WD1 may be determined so that it can be seen. In FIG. 1, there is one effective line L1, but two effective lines may be provided in accordance with the interval (pitch interval) PP between the symbols arranged in two horizontal rows.
[0189]
Further, since the diameter R of each main reel MR1, MR2, MR3 is about 95 mm or more and about 140 mm or less, the vertical width of the first transparent window WD1 is also about 95 mm or more and about 140 mm according to these diameters R. The rotation operation of the main reels MR1, MR2, MR3 as a whole may be made visible. Thus, even if the vertical width of the first transparent window WD1 is determined to be about 120 mm so that the rotation operation of the entire main reels MR1, MR2, MR3 can be visually observed, the main reel device 100 itself is small in size. The occupied area (display area) of the first transparent window WD1 in the front panel portion including the upper panel portion 13 and the middle panel portion 14 determined to have the horizontal width WAA and the vertical width TAA shown in FIG. It is possible to relatively enlarge the area related to the effect for providing the display device or the like.
[0190]
That is, the diameter R of each main reel MR1, MR2, MR3 is determined to any value within the range of about 95 mm or more and about 140 mm or less, and each reel tape TMP1, MTP2, MTP3 is determined according to any one of the diameters R. The main reels MR1, MR2, and MR3 in which the diameter R and the number of symbols K are changed can be realized by determining the number of symbols K of 12 or more and 15 or less. The vertical width of the first transparent window WD1 can be determined in any one of the ranges of the diameter R of the main reels MR1, MR2, MR3 from one symbol (one row). From this, it is possible to realize the small main reel device 100 with various sizes, and also to present the game result to the player by setting the vertical width of the first transparent window WD1 to various sizes. it can. It is also possible to adjust the overall design of the slot machine and improve the degree of freedom of design.
[0191]
The main reel device 100 of the present embodiment includes three main reels MR1, MR2, MR3, and the horizontal width of each main reel MR1, MR2, MR3 is approximately the same as the horizontal width WT of the tape reels MTP1, MTP, MTP3. The main reels MR1, MR2, and MR3 are accommodated in the reel case main body 101 and the reel case cover 102 at a slight interval so as not to contact each other. For this reason, the width of the first transparent window WD1 is also determined to be a width for making these main reels MR1, MR2, MR3 visible.
[0192]
Therefore, as described above, the lateral width WT of the tape reels MTP1, MTP2, and MTP3 is set to about 44 mm, thereby reducing the overall lateral width of the main reels MR1, MR2, and MR3 and also reducing the lateral width of the first transparent window WD1. Therefore, it is possible to relatively enlarge the area related to the effect in the front panel portion.
[0193]
Furthermore, in the present embodiment, the main reel device 100 is configured by arranging three main reels MR1, MR2, MR3 in a horizontal row, but the main reel having four or more main reels arranged in a horizontal row. Even if the apparatus is configured, it is possible to relatively enlarge the area related to the effect in the front panel section. That is, if four or more main reels are arranged in a horizontal row, the width of the entire main reel is naturally increased. However, as described above, the diameter R of each main reel is small enough to satisfy a predetermined condition. Therefore, since the vertical width becomes small in the first place, it is possible to relatively enlarge the area related to the effect in the front panel portion.
[0194]
Furthermore, even when the width WT of each tape reel is set to 44 mm or more, the diameter R of each main reel is small enough to satisfy a predetermined condition, so that the vertical width is reduced in the first place. Can be enlarged.
[0195]
Further, since the main reel device 100 is small in size including the main reels MR1, MR2, MR3 and the stepping motors MM1, MM2, MM3, it is attached to the back side of the front door 11 as shown in FIG. Therefore, it is not necessary to accommodate in the base 12 like a conventional large main reel. This means that the main reel device 100 can be provided freely in the slot machine 10 that has a limited volume, so that the degree of freedom in design is improved and the assembly process is improved. And simplification and rationalization of the internal structure of the slot machine 100 can be realized. Then, in the space vacated by the above-described simplification and rationalization of the internal structure, for example, as shown in FIG. It is possible to entertain the player by displaying various effects.
[0196]
Here, in the slot machine 10 of this embodiment, setting the display area of the main reel device 100 and the production area for production as follows improves the visibility for the player and makes it more effective. This is desirable from the standpoint of directing and having the player enjoy it.
[0197]
That is, as schematically shown in FIG. 13, the entire panel portion composed of the front panel portion (the upper panel portion 13 and the middle panel portion 14), the operation portion 16, and the lower panel portion 15, that is, faces the player. The “front panel portion” has a width WAA of about 475 mm and a vertical width (height) TA of about 810 mm, while the main reels MR1, MR2, and MR3 provided in the main reel device 100 are The width WWD1 of the first transparent window WD1 that can be visually recognized is set to a width that allows the three main reels MR1, MR2, and MR3 to be simultaneously viewed, and each main reel MR1, MR2 is set to have a vertical width TWD1 of about 25 mm or more. , MR3 is preferably set in the range of diameter R or less.
[0198]
As a specific example, the lateral width WT of each main reel MR1, MR2, MR3 is designed to be within the lateral width WWD1 of the first transparent window WD1, the lateral width WWD1 of the first transparent window WD1 is about 160 mm, and the vertical width is about TWD1. When set to about 80 mm, the size of the front panel portion and the display area of the first transparent window WD1 can be set to a visually stable ratio.
[0199]
Thus, when the display area (horizontal width WWD1 and vertical width TWD1) of the first transparent window WD1 is determined, the player sees at least one horizontal line of the symbols drawn on the outer peripheral surface of the main reels MR1, MR2, MR3. And you can see the game results. Furthermore, since the occupied area (WWD1 × TWD1) of the first transparent window WD1 in the front panel portion (the width WAA and the length TA) can be relatively reduced, the occupied area for effect display can be expanded. More effective presentation display can be performed.
[0200]
Further, the display area (horizontal width WWD1 and vertical width TWD1) of the first transparent window WD1 is related to the size (horizontal width WAA and vertical width TAA) of the “front panel portion” that is the main area for effect display. You may decide.
[0201]
That is, the first transparent window WD1 that allows the main reels MR1, MR2, and MR3 provided in the main reel device 100 to be visually recognized with respect to the “front panel portion” having the horizontal width WAA of about 475 mm and the vertical width TAA of about 462 mm. The horizontal width WWD1 is set to a width that allows the three main reels MR1, MR2, and MR3 to be seen simultaneously, and the vertical width TWD1 is set to a range that is about 25 mm or more and less than the diameter R of each main reel MR1, MR2, MR3. It is preferable to do.
[0202]
As a specific example, the width WT of each main reel MR1, MR2, MR3 is within the width WWD1 of the first transparent window WD1 with respect to the “front panel portion” having a width WAA of about 475 mm and a length of TAA of about 462 mm. When designed and the horizontal width WWD1 of the first transparent window WD1 is set to about 160 mm and the vertical width is set to about 80 mm, the size of the front panel portion and the display area of the first transparent window WD1 is visually observed. A stable ratio can be achieved.
[0203]
Further, the size of the second transparent window WD2 that allows the sub reels SR1, SR2, SR3 provided in the sub reel device 200 to be visually recognized and the size of the first transparent window WD1 described above are determined based on a predetermined area ratio. May be.
[0204]
As a specific example, the area (WWD2 × TWD2) of the display area of the second transparent window WD2 with respect to the area (WWD1 × TWD1) of the display area of the first transparent window WD1 is expressed by the following equation (11). In addition, when it is set to about 5 times or more, it is preferable in order to achieve a sense of stability visually and to display an effective presentation.
[0205]
[Expression 14]

[0206]
More specifically, the width WWD2 of the second transparent window WD2 is set to about 390 mm and the vertical width TWD2 is set to about 210 mm, and the diameter of each of the three sub reels SR1, SR2, SR3 is set to about 210 mm. The overall width of the three sub-reels SR1, SR2 and SR3 is designed to be about 390 mm, while the width WWD1 of the first transparent window WD1 is set to about 160 mm and the vertical width is set to about 80 mm. Each main reel MR1, MR2, MR3 has a diameter R of about 120 mm as described above, and the main reels MR1, MR2, MR3 have an overall width that matches the width WWD1 (about 160 mm) of the first transparent window WD1. By determining the lateral width WT of MR1, MR2 and MR3, it is possible to obtain a ratio with a sense of stability visually.
[0207]

[0209]
In addition, when such a CRT display or a flat plate type two-dimensional EL device (color liquid crystal display, organic EL display, dot matrix type color LED display in which a large number of light-emitting diodes are two-dimensionally arranged, etc.) The condition of the display area size (horizontal width WWD2 and TWD2) of the second transparent window WD2 with respect to the display area size (horizontal width WWD1 and TWD1) of the first transparent window WD1 described with reference to FIG. 13 is satisfied. In addition, it is desirable to determine the size of the display surface of each effect display device.
[0210]
Further, a transmissive liquid crystal display or a transmissive organic EL display is disposed on almost the entire middle panel portion 14 shown in FIG. 1, and a large sub-reel device 200 is provided on the back side (base 12 side) of these displays. Thus, an effect display may be performed by combining the images displayed on these displays and the movement of the sub reel device 200.
[0211]
Further, not only the middle panel portion 14 but also the transmissive liquid crystal display and the transmissive organic EL display are arranged almost entirely on the upper panel 13 and the middle panel portion 14, and the back side (base 12 side) of these displays. A large sub-reel device 200 may be provided, and an effect display may be performed by combining the images displayed on these displays and the movement of the sub-reel device 200.
