Description

【０００１】
【発明の属する技術分野】
本発明は、合成樹脂製の前枠と、この前枠に遊技者側の前面側にて開閉可能となるように取り付けられて、略中央部に遊技領域を視認可能とする窓部を有する前面カバー部材とが設けられた遊技機に関するものである。
【０００２】
【従来の技術】
従来より、合成樹脂製の前枠と、この前枠に遊技者側の前面側にて開閉可能となるように取り付けられて、略中央部に遊技領域を視認可能とする窓部を有する前面カバー部材とが設けられた遊技機に関し種々提案されている。
例えば、合成樹脂製の前枠の上縁と左右両側縁に、前面側に突出する線状の補強リブを一体成形するようにし、前面カバー部材としてのガラス扉枠や前面板の側端面を該補強リブで覆った遊技機が提案されている（例えば、特許文献１参照。）
これにより、この補強リブによって合成樹脂製の前枠の剛性を確実に向上させることができ、また、ガラス扉枠や前面板の側端面が覆われるため不正なこじ開け行為を防止することができる。
【０００３】
【特許文献１】
特開平９−１１７５５３号公報（段落（００１１）、図３、図１１）
【０００４】
【発明が解決しようとする課題】
しかしながら、上述した遊技機では、前枠は合成樹脂製であり、大型部品であるため、成形精度の制約から該前枠の補強リブと前面カバー部材の側端面との間に隙間が生じ、遊技機の前面部周囲の見栄えが悪くなるという問題がある。また、該前枠の補強リブと前面カバー部材の側端面との間の隙間から薄いプラスチック板等（例えば、厚さ０．５ｍｍ程度のプラスチック板等）を挿入し、遊技領域の電動役物などを操作して不正に賞球（所謂、景品球として払いだされる遊技球）を獲得することが可能になるという問題がある。
【０００５】
そこで、本発明は、上述した問題点を解決するためになされたものであり、合成樹脂製の前枠の剛性を向上させつつ、遊技機の前面部周囲の見栄えを良くすると共に、前面カバー部材の側端面と合成樹脂製の前枠との間に生じる隙間からの薄いプラスチック板等の遊技領域への侵入が極めて困難な遊技機を提供することを目的とする。
【０００６】
【課題を解決するための手段】
前記目的を達成するため請求項１に係る遊技機は、合成樹脂製の前枠と、前記前枠に遊技者側の前面側にて開閉可能となるように取り付けられて、略中央部に遊技領域を視認可能とする窓部を有する前面カバー部材とを備えた遊技機において、前記前枠は、前記前面カバー部材を閉じた場合に、該前面カバー部材の内壁面近傍の表面部に前面側方向に立設される補強リブ部を有し、前記補強リブ部は、該前面カバー部材の上辺部及び左右側壁部のほぼ全長に渡って対向するように形成されていることを特徴とする。
【０００７】
このような特徴を有する請求項１に係る遊技機においては、合成樹脂製の前枠は、略中央部に遊技領域を視認可能とする窓部を有する前面カバー部材を閉じた場合に、該前面カバー部材の内壁面近傍の表面部には、この前面カバー部材の上辺部及び左右側壁部のほぼ全長に渡って対向するように前面側方向に立設される補強リブ部が設けられている。
これにより、前面カバー部材を閉じた場合に、該前面カバー部材の内壁面の上辺部及び左右側辺部のほぼ全長に渡って対向するように前面側方向に立設される補強リブ部によって、合成樹脂製の前枠の剛性を確実に向上させることができると共に、該前面カバー部材を閉じた場合には、この補強リブ部は前面カバー部材によって覆われるため、遊技機の前面側周縁部に隙間などが発生することなく、見栄えを良くすることできる。また、合成樹脂製の前枠と前面カバー部材の側端面との間の隙間から薄いプラスチック板等を挿入しても、このプラスチック板は遊技領域に達するためには、補強リブ部の外側の側壁部に当たった後、略直角に曲がり、更に、この補強リブ部を乗り越える必要があるため、薄いプラスチック板などの遊技領域への侵入を極めて困難にすることが可能となる。
尚、補強リブ部は、前面カバー部材の上辺部及び左右側壁部の全長に渡って対向するように連続して前面側方向に立設してもよいが、前面カバー部材を枢支するヒンジ部材等が取り付けられて、該ヒンジ部材等によって前面カバー部材の側面部を覆う部分に対向する前枠の前面部には、この補強リブ部を立設せず、一部分途切れた状態で該補強リブ部を立設する構成にしてもよい（即ち、前面カバー部材の上辺部及び左右側壁部のほぼ全長に渡って対向するように補強リブ部を立設する構成にしてもよい。）。これにより、ヒンジ部材などが取り付けられる部分の複雑な形状に合わせて補強リブ部を形成する必要が無く、該補強リブ部の形状が簡易な形状となり前枠の成形加工を容易に行うことができる。また、補強リブ部の途切れた部分に対向する前面カバー部材の側面部は、ヒンジ部材等によって覆われるため、この補強リブ部の途切れた部分から薄いプラスチック板などの遊技領域への侵入を極めて困難にすることが可能となる。
【０００８】
また、請求項２に係る遊技機は、請求項１に記載の遊技機において、前記前枠は、前記補強リブ部の外側の側壁部に沿って形成される溝部を有し、前記溝部は、前記側壁部の基端部に沿った第１壁面と、前記第１壁面と外側方向に鋭角を形成する第２壁面と、を有することを特徴とする。
【０００９】
このような特徴を有する請求項２に係る遊技機では、合成樹脂製の前枠と前面カバー部材の側端面との間の隙間から薄いプラスチック板等を挿入した場合に、このプラスチック板が補強リブ部の外側の側壁部に当たって遊技機の後側方向に曲がった時は、この側壁部の基端部に沿って形成される溝部の第１壁面に沿って進入後、この第１壁面と鋭角をなす第２壁面に沿うように溝部内に進入するため、行き止まりとなり、薄いプラスチック板などの遊技領域への侵入を極めて困難にすることが可能となる。
【００１０】
また、請求項３に係る遊技機は、請求項２に記載の遊技機において、前記第１壁面は、前記前枠の表面部に略垂直な垂直面であることを特徴とする。
【００１１】
このような特徴を有する請求項３に係る遊技機では、合成樹脂製の前枠と前面カバー部材の側端面との間の隙間から薄いプラスチック板等を挿入した場合に、このプラスチック板が補強リブ部の外側の側壁部に当たって遊技機の後側方向に曲がった時は、この側壁部の基端部に沿って形成される前枠の表面部に略垂直な垂直面に沿ってスムーズに進入後、この垂直面と鋭角をなす第２壁面に沿うように溝部内に進入するため、薄いプラスチック板は、この垂直面の奥側端縁部で第２壁面側方向に押圧された状態で行き止まりとなり、遊技領域への侵入を更に極めて困難にすることが可能となる。
【００１２】
また、請求項４に係る遊技機は、請求項２に記載の遊技機において、前記第１壁面は、前記前枠の表面部に略垂直な垂直面よりも内側方向に傾斜するように形成されていることを特徴とする。
【００１３】
このような特徴を有する請求項４に係る遊技機では、合成樹脂製の前枠と前面カバー部材の側端面との間の隙間から薄いプラスチック板等を挿入した場合に、このプラスチック板が補強リブ部の外側の側壁部に当たって遊技機の後側方向に曲がった時は、この側壁部の基端部に沿って前枠の表面部に略垂直な垂直面よりも内側方向に傾斜するように形成された第１壁面に沿って更にスムーズに溝部内に進入するため、薄いプラスチック板は、この第１壁面と鋭角をなす第２壁面とで形成される奥側端縁部で遊技機の裏側方向に押圧された状態で行き止まりとなり、遊技領域への侵入を更に極めて困難にすることが可能となる。
【００１４】
また、請求項５に係る遊技機は、請求項２乃至請求項４のいずれかに記載の遊技機において、前記第２壁面は、前記第１壁面と外側方向に鋭角を形成する平面状の傾斜面であることを特徴とする。
【００１５】
このような特徴を有する請求項５に係る遊技機では、第２壁面は、第１壁面と外側方向に鋭角を形成する平面状の傾斜面であるため、溝部内に進入した薄いプラスチック板は、この溝部の全長に渡っていずれの位置においても、第１壁面の奥側端縁部で第２壁面側方向に押圧された状態で行き止まりとなり、遊技領域への侵入を更に極めて困難にすることが可能となる。
【００１６】
また、請求項６に係る遊技機は、請求項５に記載の遊技機において、前記第２壁面は、該第２壁面の前記前枠の表面側方向の端縁部が断面略円弧状に形成されていることを特徴とする。
【００１７】
このような特徴を有する請求項６に係る遊技機では、合成樹脂製の前枠と前面カバー部材の側端面との間の隙間から薄いプラスチック板等を挿入した場合に、第２壁面の前記前枠の表面側方向の端縁部が断面略円弧状に形成されているため、この薄いプラスチック板の先端部が補強リブ部の外側の側壁部に当たった際に、遊技機の裏側方向により曲がり易くなり、溝部内に進入する可能性を高くすることができ、このプラスチック板の遊技領域への侵入を更に極めて困難にすることが可能となる。
【００１８】
また、請求項７に係る遊技機は、請求項２乃至請求項４のいずれかに記載の遊技機において、前記第２壁面は、前記第１壁面側に突き出る断面略円弧状の傾斜面であることを特徴とする。
【００１９】
このような特徴を有する請求項７に係る遊技機では、合成樹脂製の前枠と前面カバー部材の側端面との間の隙間から薄いプラスチック板等を挿入した場合に、第２壁面は、第１壁面側に突き出る断面略円弧状の傾斜面に形成されているため、この薄いプラスチック板の先端部が補強リブ部の外側の側壁部に当たった際に、遊技機の裏側方向により曲がり易くなると共に、溝部内に進入した薄いプラスチック板は、この溝部の全長に渡っていずれの位置においても、第１壁面の奥側端縁部で該第２壁面に押し付けられるように押圧された状態で行き止まりとなり、遊技領域への侵入を更に極めて困難にすることが可能となる。
【００２０】
また、請求項８に係る遊技機は、請求項２乃至請求項７のいずれかに記載の遊技機において、前記第２壁面の前記前枠の表面側方向の端縁部は、前記前面カバー部材の後側方向の端面内に対向するように形成されていることを特徴とする。
【００２１】
このような特徴を有する請求項８に係る遊技機では、溝部を構成する第２壁面の前枠の表面側方向の端縁部は、前面カバー部材の後側方向の端面内に対向するように形成されているため、この前面カバー部材の後側方向の端面の内側端縁部は、前枠の補強リブ部の基端部に形成される溝部の幅内に位置することとなる。
これにより、合成樹脂製の前枠と前面カバー部材の側端面との間の隙間から薄いプラスチック板等を挿入した場合に、このプラスチック板等が補強リブ部の外側の側壁部に当たった際に、このプラスチック板等の溝部に対向する部分の補強リブ部側の表面部が、前面カバー部材の後側方向の端面の内側端縁部に当接するため、溝部を形成する第１壁面に沿って第２壁面方向に強制的に曲げられつつ溝部内に進入させられて、該溝部の鋭角な奥側端縁部で行き止まりとなり、薄いプラスチック板などの遊技領域への侵入を極めて困難にすることが可能となる。
【００２２】
更に、請求項９に係る遊技機は、請求項８に記載の遊技機において、前記前面カバー部材は、前記溝部に対向する内側周縁部に形成される案内リブ部を有し、前記案内リブ部は、該前面カバー部材を閉じた場合に、前記溝部に挿入されることを特徴とする。
【００２３】
このような特徴を有する請求項９に係る遊技機では、合成樹脂製の前枠と前面カバー部材の側端面との間の隙間から薄いプラスチック板等を挿入した場合には、このプラスチック板等は前面カバー部材の溝部に挿入される案内リブ部に沿って、該溝部を形成する第２壁面に沿うように強制的に曲げられつつ溝部内に進入するため、該溝部の鋭角な奥側端縁部で行き止まりとなり、薄いプラスチック板などの遊技領域への侵入を更に困難にすることが可能となる。
【００２４】
【発明の実施の形態】
以下、本発明に係る遊技機をパチンコ機について具体化した第１実施形態乃至第９実施形態を図面を参照して詳細に説明する。
（第１実施形態）
先ず、第１実施形態に係るパチンコ機の概略構成について図１乃至図３に基づき説明する。
図１乃至図３に示すように、第１実施形態に係るパチンコ機１は、所定量のパチンコ球を賞球として払い出す、いわゆる第１種パチンコ機で、一般にＣＲ機（カードリーディング機）と称され、カード式球貸機とパチンコ機１とによって構成され、これらは対をなして設置されるが、図１及び図２においては、カード式球貸機の図示を省略している。パチンコ機１は、木製の外枠２に対して合成樹脂製の前枠３が、前枠取付用ヒンジを構成する上ヒンジ４及び下ヒンジ５を介して外枠２に対して開閉自在に取り付けられている。そして、この前枠３のほぼ上半分の前側には、樹脂製の前面カバー部材７が左端縁部の上下を軸支されて開閉自在に取付けられている。また、この前面カバー部材７のほぼ中央部には略円形の窓部８が開設され、この窓部８の外周縁部に形成されるガラス保持枠に装着された２枚のガラスを通して遊技領域を見ることができるように構成されている。また、前面カバー部材７の窓部８の上端縁部には、フルカラーの発光ダイオードが内蔵され、遊技中のエラーを表示するエラー表示電飾ランプ１０が取付けられている。また、このエラー表示電飾ランプ１０の左右外側には、「当たり」等の発生を報知したり遊技中に光演出をする各電飾ランプ１１が取付けられている。また、前面カバー部材７の前面部分は、不透明な合成樹脂製の前面部材１３で覆われており、この各電飾ランプ１０、１１と窓部８の上端周縁部との間に、不図示のフルカラーダイオードが左右方向に内蔵され、遊技中に光演出が行われる。
【００２５】
また、前面カバー部材７の右側中央部には、前枠３及び前面カバー部材７を施錠する施錠装置（不図示）を操作するための鍵挿入部１２が設けられている。前面カバー部材７を開くためには、この鍵挿入部１２に所定のキーを挿入して所定方向に回せば、施錠装置のロック状態が解除されて、前面カバー部材７のみがオープンされる。
【００２６】
また、この前面カバー部材７の下側には、公知の賞球払出装置（特開平１１−３０９２６５号公報等参照）を介して払い出される賞球を受ける上皿１５がスピーカ１５Ａを内蔵して樹脂製プレート１６に配設されている。また、このプレート１６は、左端縁部の上下を軸支されて、前面カバー部材７を開放後、内側に設けられた不図示のレバーを下げることにより開放できるように取付けられている。また、この上皿１５の中央前面部には、カード式球貸機の操作ボタン１５Ｂ、１５Ｃ及びカード残高表示装置１５Ｄが設けられている。そして、その上皿１５の下には、下皿１８が配設される。また、上皿１５に連通する不図示の球送り機構を介して上皿１５のパチンコ球が操作ハンドル１９に連結された不図示の発射装置へ送られるよう構成されている。
【００２７】
また、図２に示すように、前枠３の前面カバー部材７に対向する部分の略中央部には不図示の遊技盤などが着脱可能に配設される正面視略四角形の開口部２１が設けられている。また、この開口部２１の上端縁部及び左右端縁部の周縁には、補強リブ部２３が前面カバー部材７の上辺部及び左右側壁部のほぼ全長に対向するように、該前枠３の表面部から略垂直外側方向に突き出すように直線状に形成されている。また、後述のように補強リブ部２３の外側側壁部２３Ａの基端部には、溝部２４が形成されている（図４参照）。そして、図１に示すように、前枠３の前面側に前面カバー部材７を取り付けて閉じた場合には、各補強リブ部２３及び溝部２４は、該前面カバー部材７で覆われる（図５参照）。
【００２８】
次に、前枠３の前面部に形成される補強リブ部２３及び溝部２４について図４に基づいて説明する。
図４に示すように、補強リブ部２３は、側断面略長方形で前枠３の前側表面部から略垂直に突き出るように一体成形されている。また、この補強リブ部２３の前枠３の表面部からの高さ寸法は、後述のように上端面部が前面カバー部材７の裏側面近傍に位置し、該前面カバー部材７の裏側面に当たらないように形成されている。
また、この補強リブ部２３の外側側壁部２３Ａの基端部に沿って形成される溝部２４は、前枠３の表面部に略垂直な垂直面２４Ａと、この垂直面２４Ａの裏側方向（図４中、下側方向）端縁部から、鋭角を形成して外側方向（図４中、右側上方向）に延出される平面状の傾斜面２４Ｂと、から構成されている。また、この傾斜面２４Ｂの前枠３の表面側端縁部は、後述のように前面カバー部材７の内側側壁部よりも内側に位置するように形成されている（図５参照）。
【００２９】
次に、パチンコ機１の前面カバー部材７を閉じた状態の補強リブ部２３及び溝部２４について図５に基づいて説明する。
図５に示すように、パチンコ機１の前面カバー部材７を閉じた状態では、該前面カバー部材７の上辺部及び左右側辺部の後側端面部（図５中、下側端面部）が前枠３の前側周縁部表面（図５中、上側周縁部表面）に当接され、該前枠３の前面部は、前面カバー部材７によってほぼ覆われ、遊技者側の前面側から見えなくなる。また、溝部２４を形成する傾斜面２４Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部よりも少し内側になる位置に形成されている。また、補強リブ部２３の先端部（図５中、上端面部）は、前面カバー部材７の裏側面の近傍まで延出されている。
これにより、例えば、前面カバー部材７の側壁部と前枠３との隙間から薄いプラスチック板（例えば、厚さ寸法約０．５ｍｍのプラスチック板）を挿入した場合には、該プラスチック板の先端部が補強リブ部２３の外側側壁部２３Ａに当接後、溝部２４の垂直面２４Ａに沿って裏側方向（図５中、下側方向）に少しでも曲がれば、矢印２８方向に溝部２４内に進入して、該垂直面２３Ａと傾斜面２４Ｂとで形成される溝部２４の奥側で行き止まりとなり、補強リブ部２３を乗り越えて、遊技領域方向（図５中、左方向）に侵入できなくなる。
【００３０】
ここで、垂直面２４Ａは、第１壁面として機能する。また、傾斜面２４Ｂは、第２壁面として機能する。
【００３１】
以上説明した通り第１実施形態に係るパチンコ機１では、合成樹脂製の前枠３の前面部には、前面カバー部材７を閉じた場合に、該前面カバー部材７の内壁面の上辺部及び左右側辺部のほぼ全長に渡って対向するように補強リブ部２３が立設されている。また、補強リブ部２３の外側側壁部２３Ａの基端部には、この前枠３の表面部に略垂直な垂直面２４Ａと、この垂直面２４Ａの裏側方向端縁部から鋭角を形成して外側方向に延出される傾斜面２４Ｂとから構成される溝部２４が形成されている。また、この傾斜面２４Ｂの前枠３の表面側端縁部は、前面カバー部材７の内側側壁部よりも内側に位置するように形成されている。
【００３２】
従って、この補強リブ部２３によって、合成樹脂製の前枠３の剛性を確実に向上させることができると共に、該前面カバー部材７を閉じた場合には、この補強リブ部２３及び溝部２４は前面カバー部材７によって覆われるため、パチンコ機１の前面側周縁部に隙間などが発生することなく、見栄えを良くすることできる。
また、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入しても、このプラスチック板は遊技領域に達するためには、補強リブ部２３の外側の側壁部に当たった後、略直角に曲がり、更に、この補強リブ部２３を乗り越える必要があるため、薄いプラスチック板等の遊技領域への侵入を極めて困難にすることが可能となる。また、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入した場合に、このプラスチック板が補強リブ部２３の外側側壁部２３Ａに当たってパチンコ機１の後側方向に曲がった時は、この外側側壁部２３Ａの基端部に沿って形成される溝部２４の該前枠３の表面部に略垂直な垂直面２４Ａに沿って傾斜面２４Ｂに沿うように溝部２４内に進入するため、行き止まりとなり、薄いプラスチック板などの遊技領域への侵入を更に極めて困難にすることが可能となる。
【００３３】
（第２実施形態）
次に、第２実施形態に係るパチンコ機について図６乃至図９に基づいて説明する。尚、上記第１実施形態に係るパチンコ機１と同一符号は、上記第１実施形態に係るパチンコ機１と同一あるいは相当部分を示すものである。
この第２実施形態に係るパチンコ機の概略構成は、第１実施形態に係るパチンコ機１の構成とほぼ同じ構成である。但し、第２実施形態に係るパチンコ機の合成樹脂製の前枠の前面部に形成される補強リブ部及び溝部の構成は、後述のように第１実施形態に係るパチンコ機１の補強リブ部２３及び溝部２４の構成と異なっている。
【００３４】
図６及び図７に示すように、第２実施形態に係るパチンコ機３１の概略構成は、上記第１実施形態に係るパチンコ機１とほぼ同じ概略構成である（図１乃至図３参照）。但し、図７に示すように、前枠３の略中央部に設けられる開口部２１の上端縁部及び左右端縁部の周縁には、補強リブ部３２が前面カバー部材７の上辺部及び左右側辺部のほぼ全長に対向するように、該前枠３の表面部から略垂直外側方向に突き出すように直線状に形成されている。また、後述のように補強リブ部３２の外側側壁部３２Ａの基端部には、溝部３３が形成されている（図８参照）。そして、図６に示すように、前枠３の前面側に前面カバー部材７を取り付けて閉じた場合には、各補強リブ部３２及び溝部３３は、該前面カバー部材７で覆われる（図９参照）。
【００３５】
次に、前枠３の前面部に形成される補強リブ部３２及び溝部３３について図８に基づいて説明する。
図８に示すように、補強リブ部３２は、側断面略長方形で前枠３の前側表面部から略垂直に突き出るように一体成形されている。また、この補強リブ部３２の前枠３の表面部からの高さ寸法は、後述のように上端面部が前面カバー部材７の裏側面近傍に位置し、該前面カバー部材７の裏側面に当たらないように形成されている。また、この補強リブ部３２の上端面の外側側縁部には、面取部３２Ａが形成され、前面カバー部材７を遊技者側の前面側に開く際に、この前面カバー部材７の裏側端面部と干渉しないように構成されている。尚、この補強リブ部３２は、第１実施形態に係るパチンコ機１の開口部２１の周縁部に形成される補強リブ部２３の立設される位置よりも少し外側方向の位置に形成されている。即ち、該前面カバー部材７を閉じた際に、補強リブ部３２は、該前面カバー部材７の裏側側壁面に対して第１実施形態に係るパチンコ機１の補強リブ部２３よりも近い位置に立設されている。
【００３６】
また、この補強リブ部３２の外側側壁部３２Ｂの基端部に沿って形成される溝部３３は、前枠３の表面部に略垂直な垂直面３３Ａと、この垂直面３３Ａの裏側方向（図８中、下側方向）端縁部から、鋭角を形成して外側方向（図８中、右側上方向）に延出される平面状の傾斜面３３Ｂと、から構成されている。また、この傾斜面３３Ｂの前枠３の表面側端縁部は、後述のように前面カバー部材７の前枠３の周縁表面部に対向する裏側端面内に対向するように形成されている（図９参照）。
【００３７】
次に、パチンコ機３１の前面カバー部材７を閉じた状態の補強リブ部３２及び溝部３３について図９に基づいて説明する。
図９に示すように、パチンコ機３１の前面カバー部材７を閉じた状態では、該前面カバー部材７の上辺部及び左右側辺部の後側端面部（図９中、下側端面部）が前枠３の前側周縁部表面（図９中、上側周縁部表面）に当接され、該前枠３の前面部は、前面カバー部材７によってほぼ覆われ、遊技者側の前面側から見えなくなる。また、溝部３３を形成する傾斜面３３Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部の内側側縁部と外側側縁部との間の位置に対向するように形成されている。例えば、図９（Ｂ）に示すように、溝部３３を形成する傾斜面３３Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部の内側側縁部よりも少し外側方向の位置に対向する位置に形成されている。また、補強リブ部３２の先端部（図９中、上端面部）は、前面カバー部材７の裏側面の近傍まで延出されている。
【００３８】
これにより、例えば、前面カバー部材７の側壁部と前枠３との隙間から薄いプラスチック板（例えば、厚さ寸法約０．５ｍｍのプラスチック板）等を挿入した場合には、該プラスチック板の先端部が補強リブ部３２の外側側壁部３２Ａに当接すると共に、溝部３３の開口部（図９（Ｂ）中、上端部）でプラスチック板の片側表面部が前面カバー部材７の上辺部及び左右側辺部の後側端面部の内側側縁部に当接する。従って、プラスチック板の先端部は、溝部３３の垂直面３３Ａに沿って裏側方向（図９中、下側方向）に曲がり易くなる。そして、図９（Ｂ）に示すように、矢印３５方向に溝部３３内に進入して、該垂直面３３Ａと傾斜面３３Ｂとで形成される溝部３３の奥側で行き止まりとなり、補強リブ部３２を乗り越えて、遊技領域方向（図９中、左方向）に侵入できなくなる。
【００３９】
ここで、垂直面３３Ａは、第１壁面として機能する。また、傾斜面３３Ｂは、第２壁面として機能する。
【００４０】
以上説明した通り第２実施形態に係るパチンコ機３１では、合成樹脂製の前枠３の前面部には、前面カバー部材７を閉じた場合に、該前面カバー部材７の内壁面の上辺部及び左右側辺部のほぼ全長に渡って対向するように補強リブ部３２が立設されている。また、補強リブ部３２の外側側壁部３２Ｂの基端部には、この前枠３の表面部に略垂直な垂直面３３Ａと、この垂直面３３Ａの裏側方向端縁部から鋭角を形成して外側方向に延出される傾斜面３３Ｂとから構成される溝部３３が形成されている。また、この傾斜面３３Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部の内側側縁部と外側側縁部との間の位置に対向するように形成されている。
【００４１】
従って、この補強リブ部３２によって、合成樹脂製の前枠３の剛性を確実に向上させることができると共に、該前面カバー部材７を閉じた場合には、この補強リブ部３２は前面カバー部材７によって覆われるため、パチンコ機３１の前面側周縁部に隙間などが発生することなく、見栄えを良くすることできる。
また、溝部３３の傾斜面３３Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部の内側側縁部と外側側縁部との間の位置に対向するように形成されているため、補強リブ部３２を前面カバー部材７の上辺部及び左右側辺部の内側側壁部により近づけて立設することが可能となる。このため、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入しても、このプラスチック板は遊技領域に達するためには、補強リブ部３２の外側の側壁部に当たった後、略直角に曲がり、更に、この補強リブ部３２を乗り越える必要があるため、薄いプラスチック板等の遊技領域への侵入を困難にすることが可能となる。
また、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入した場合には、プラスチック板の先端部は、溝部３３の垂直面３３Ａに沿って傾斜面３３Ｂ方向に強制的に曲げられつつ溝部３３内に進入させられて、該溝部３３の鋭角な底部で行き止まりとなり、薄いプラスチック板などの遊技領域への侵入を極めて困難にすることが可能となる。
【００４２】
（第３実施形態）
次に、第３実施形態に係るパチンコ機について図１０乃至図１４に基づいて説明する。尚、上記第１実施形態に係るパチンコ機１と同一符号は、上記第１実施形態に係るパチンコ機１と同一あるいは相当部分を示すものである。
この第３実施形態に係るパチンコ機の概略構成は、第１実施形態に係るパチンコ機１の構成とほぼ同じ構成である。但し、第３実施形態に係るパチンコ機の合成樹脂製の前枠の前面部に形成される補強リブ部及び溝部の構成と、前面カバー部材の該溝部に対向する部分の形状は、後述のように第１実施形態に係るパチンコ機１の構成と異なっている。
【００４３】
図１０乃至図１２に示すように、第３実施形態に係るパチンコ機４１の概略構成は、上記第１実施形態に係るパチンコ機１とほぼ同じ概略構成である（図１乃至図３参照）。但し、図１１に示すように、前枠３の略中央部に設けられる開口部２１の上端縁部及び左右端縁部の周縁には、補強リブ部４２が前面カバー部材７の上辺部及び左右側壁部のほぼ全長に対向するように、該前枠３の表面部から略垂直外側方向に突き出すように直線状に形成されている。また、後述のように補強リブ部４２の外側側壁部４２Ａの基端部には、溝部４３が形成されている（図１３参照）。
また、図１２に示すように、前面カバー部材７の溝部４３に対向する上辺部及び左右側辺部の内側周縁部には、案内リブ部が裏側方向（図１２（Ｂ）中、上側方向）に延出されて形成されている（図１４参照）。そして、図１０に示すように、前枠３の前面側に前面カバー部材７を取り付けて閉じた場合には、各補強リブ部４２及び溝部４３は、該前面カバー部材７で覆われる（図１４参照）。
【００４４】
次に、前枠３の前面部に形成される補強リブ部４２及び溝部４３について図１３に基づいて説明する。
図１３に示すように、補強リブ部４２は、側断面略長方形で前枠３の前側表面部から略垂直に突き出るように一体成形されている。また、この補強リブ部４２の前枠３の表面部からの高さ寸法は、後述のように上端面部が前面カバー部材７の裏側面近傍に位置し、該前面カバー部材７の裏側面に当たらないように形成されている。また、この補強リブ部４２の上端面の外側側縁部には、面取部４２Ａが形成され、前面カバー部材７を遊技者側の前面側に開く際に、この前面カバー部材７の裏側端面部と干渉しないように構成されている。尚、この補強リブ部４２は、第１実施形態に係るパチンコ機１の開口部２１の周縁部に形成される補強リブ部２３の立設される位置よりも少し外側方向の位置に形成されている。即ち、該前面カバー部材７を閉じた際に、補強リブ部４２は、該前面カバー部材７の裏側側壁面に対して第１実施形態に係るパチンコ機１の補強リブ部２３よりも近い位置に立設されている。
【００４５】
また、この補強リブ部４２の外側側壁部４２Ｂの基端部に沿って形成される溝部４３は、前枠３の表面部に略垂直な垂直面４３Ａと、この垂直面４３Ａの裏側方向（図１３中、下側方向）端縁部から、鋭角を形成して外側方向（図１３中、右側上方向）に延出される平面状の傾斜面４３Ｂと、から構成されている。また、この傾斜面４３Ｂの前枠３の表面側端縁部は、後述のように前面カバー部材７の前枠３の周縁表面部に対向する裏側端面内に対向するように形成されている（図１４参照）。
【００４６】
次に、パチンコ機４１の前面カバー部材７を閉じた状態の補強リブ部４２、溝部４３及び案内リブ部４４の概略構成について図１４に基づいて説明する。
図１４に示すように、パチンコ機４１の前面カバー部材７を閉じた状態では、該前面カバー部材７の上辺部及び左右側辺部の後側端面部（図１４中、下側端面部）が前枠３の前側周縁部表面（図１４中、上側周縁部表面）に当接され、該前枠３の前面部は、前面カバー部材７によってほぼ覆われ、遊技者側の前面側から見えなくなる。また、溝部４３を形成する傾斜面４３Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部の内側側縁部と外側側縁部との間の位置に対向するように形成されている。例えば、図１４（Ｂ）に示すように、溝部４３を形成する傾斜面４３Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部の内側側縁部よりも少し外側方向の位置に対向する位置に形成されている。また、補強リブ部４２の先端部（図１４中、上端面部）は、前面カバー部材７の裏側面の近傍まで延出されている。
また、前面カバー部材７の上辺部及び左右側辺部の溝部４３に対向する内側周縁部には、案内リブ部４４が該溝部４３の全長に渡って略垂直外側方向（図１４中、下側方向）に突き出すように直線状に形成されている。そして、前面カバー部材７を閉じた際には、この案内リブ部４４の上端部は、溝部４３内に挿入され、該溝部４３を構成する傾斜面４３Ｂの近傍に位置するように形成されている。
【００４７】
これにより、例えば、前面カバー部材７の側壁部と前枠３との隙間から薄いプラスチック板（例えば、厚さ寸法約０．５ｍｍのプラスチック板）等を挿入した場合には、該プラスチック板の先端部が前面カバー部材７の案内リブ部４４に当接して、溝部４３の傾斜面４３Ｂに沿って裏側方向（図１４中、下側方向）に曲げられ、該溝部４３の垂直面４３Ａと傾斜面４３Ｂとで形成される溝部４３の奥側で行き止まりとなり、補強リブ部４２を乗り越えて、遊技領域方向（図１４中、左方向）に進入できなくなる。また、案内リブ部４４の高さ寸法が低くても、プラスチック板の片側表面部が、溝部４３の開口部（図１４（Ｂ）中、上端部）でこの案内リブ部４４に当接する。従って、プラスチック板の先端部は、溝部４３の垂直面４３Ａに沿って裏側方向（図１４中、下側方向）に曲げられる。そして、図１４（Ｂ）に示すように、矢印４５方向に溝部４３内に進入して、該垂直面４３Ａと傾斜面４３Ｂとで形成される溝部４３の奥側で行き止まりとなり、補強リブ部４２を乗り越えて、遊技領域方向（図１４中、左方向）に侵入できなくなる。
【００４８】
ここで、垂直面４３Ａは、第１壁面として機能する。また、傾斜面４３Ｂは、第２壁面として機能する。
【００４９】
以上説明した通り第３実施形態に係るパチンコ機４１では、合成樹脂製の前枠３の前面部には、前面カバー部材７を閉じた場合に、該前面カバー部材７の内壁面の上辺部及び左右側辺部のほぼ全長に渡って対向するように補強リブ部４２が立設されている。また、補強リブ部４２の外側側壁部４２Ｂの基端部には、この前枠３の表面部に略垂直な垂直面４３Ａと、この垂直面４３Ａの裏側方向端縁部から鋭角を形成して外側方向に延出される傾斜面４３Ｂとから構成される溝部４３が形成されている。また、この傾斜面４３Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部の内側側縁部と外側側縁部との間の位置に対向するように形成されている。また、前面カバー部材７の上辺部及び左右側辺部の溝部４３に対向する内側周縁部には、案内リブ部４４が該溝部４３の全長に渡って略垂直外側方向に突き出すように直線状に形成されている。
【００５０】
従って、この補強リブ部４２によって、合成樹脂製の前枠３の剛性を確実に向上させることができると共に、該前面カバー部材７を閉じた場合には、この補強リブ部４２及び溝部４３は前面カバー部材７によって覆われるため、パチンコ機４１の前面側周縁部に隙間などが発生することなく、見栄えを良くすることできる。
また、溝部４３の傾斜面４３Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部の内側側縁部と外側側縁部との間の位置に対向するように形成されているため、補強リブ部４２を前面カバー部材７の上辺部及び左右側辺部の内側側壁部により近づけて立設することが可能となる。このため、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入しても、このプラスチック板は遊技領域に達するためには、補強リブ部４２の外側の側壁部に当たった後、略直角に曲がり、更に、この補強リブ部４２を乗り越える必要があるため、薄いプラスチック板等の遊技領域への侵入を困難にすることが可能となる。
また、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入した場合には、プラスチック板の先端部は、該プラスチック板の先端部が前面カバー部材７の案内リブ部４４に当接して、溝部４３の傾斜面４３Ｂに沿って裏側方向に曲げられ、該溝部４３の垂直面４３Ａと傾斜面４３Ｂとで形成される溝部４３の奥側で行き止まりとなり、補強リブ部４２を乗り越えて、遊技領域方向に侵入できなくなる。また、案内リブ部４４の高さ寸法が低くても、プラスチック板の片側表面部が、溝部４３の開口部でこの案内リブ部４４に当接するため、溝部４３の垂直面４３Ａに沿って裏側方向に強制的に曲げられつつ溝部４３内に進入させられて、該溝部４３の鋭角な底部で行き止まりとなり、薄いプラスチック板などの遊技領域への侵入を極めて困難にすることが可能となる。
【００５１】
（第４実施形態）
次に、第４実施形態に係るパチンコ機について図１５に基づいて説明する。尚、上記第１実施形態に係るパチンコ機１と同一符号は、上記第１実施形態に係るパチンコ機１と同一あるいは相当部分を示すものである。
この第４実施形態に係るパチンコ機の概略構成は、第１実施形態に係るパチンコ機１の構成とほぼ同じ構成である。但し、第４実施形態に係るパチンコ機の溝部の構成は、第１実施形態に係るパチンコ機１の溝部２４の構成と異なっている。
【００５２】
図１５に示すように、第４実施形態に係るパチンコ機５１の概略構成は、上記第１実施形態に係るパチンコ機１とほぼ同じ概略構成である（図１乃至図３参照）。但し、図１５に示すように、補強リブ部２３の外側側壁部２３Ａの基端部には、溝部５２が形成されている。この溝部５２は、前枠３の表面部に略垂直な垂直面５２Ａと、この垂直面５２Ａの裏側方向（図１５中、下側方向）端縁部から、鋭角を形成して外側方向（図１５中、右側上方向）に延出される平面状の傾斜面５２Ｂと、この傾斜面５２Ｂの前枠３の表面側方向の端縁部に形成される断面略円弧状の円弧部５２Ｃと、から構成されている。また、この円弧部５２Ｃの前枠３の表面側端縁部は、前面カバー部材７の内側側壁部よりも内側に位置するように形成されている。これにより、パチンコ機５１の前面カバー部材７を閉じた状態では、該前面カバー部材７の上辺部及び左右側辺部の後側端面部（図１５中、下側端面部）が前枠３の前側周縁部表面（図１５中、上側周縁部表面）に当接され、該前枠３の前面部は、前面カバー部材７によってほぼ覆われ、遊技者側の前面側から見えなくなる。また、溝部５２を形成する円弧部５２Ｃの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部よりも少し内側になる位置に形成されている。また、補強リブ部２３の先端部（図１５中、上端面部）は、前面カバー部材７の裏側面の近傍まで延出されている。
【００５３】
従って、この補強リブ部２３によって、合成樹脂製の前枠３の剛性を確実に向上させることができると共に、該前面カバー部材７を閉じた場合には、この補強リブ部２３及び溝部５２は前面カバー部材７によって覆われるため、パチンコ機５１の前面側周縁部に隙間などが発生することなく、見栄えを良くすることできる。
また、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入しても、このプラスチック板は遊技領域に達するためには、補強リブ部２３の外側の側壁部に当たった後、略直角に曲がり、更に、この補強リブ部２３を乗り越える必要があるため、薄いプラスチック板等の遊技領域への侵入を極めて困難にすることが可能となる。また、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入した場合に、このプラスチック板が補強リブ部２３の外側側壁部２３Ａに当たった際に、円弧部５２Ｃに沿ってパチンコ機５１の後側方向に（矢印５３方向に）曲がり易くなり、この外側側壁部２３Ａの基端部に沿って形成される溝部５２の垂直面５２Ａに沿って傾斜面５２Ｂに沿うように溝部５２内に進入する可能性を高くすることができると共に、該溝部５２内に進入した場合には、行き止まりとなり、薄いプラスチック板などの遊技領域への侵入を更に極めて困難にすることが可能となる。
【００５４】
ここで、垂直面５２Ａは、第１壁面として機能する。また、傾斜面５２Ｂ及び円弧部５２Ｃは、第２壁面を構成する。
【００５５】
（第５実施形態）
次に、第５実施形態に係るパチンコ機について図１６に基づいて説明する。尚、上記第２実施形態に係るパチンコ機３１と同一符号は、上記第２実施形態に係るパチンコ機３１と同一あるいは相当部分を示すものである。
この第５実施形態に係るパチンコ機の概略構成は、第２実施形態に係るパチンコ機３１の構成とほぼ同じ構成である。但し、第５実施形態に係るパチンコ機の溝部の構成は、第２実施形態に係るパチンコ機３１の溝部３３の構成と異なっている。
【００５６】
図１６に示すように、第５実施形態に係るパチンコ機６１の概略構成は、上記第２実施形態に係るパチンコ機３１とほぼ同じ概略構成である（図６及び図７参照）。但し、図１６に示すように、補強リブ部３２の外側側壁部３２Ｂの基端部に沿って形成される溝部６２は、前枠３の表面部に略垂直な垂直面６２Ａと、この垂直面６２Ａの裏側方向（図１６中、下側方向）端縁部から、鋭角を形成して外側方向（図１６中、右側上方向）に延出される断面略円弧状の傾斜面６２Ｂと、から構成されている。また、この傾斜面６２Ｂの前枠３の表面側端縁部は、前面カバー部材７の前枠３の周縁表面部に対向する裏側端面内に対向するように形成されている。これにより、パチンコ機６１の前面カバー部材７を閉じた状態では、該前面カバー部材７の上辺部及び左右側辺部の後側端面部（図１６中、下側端面部）が前枠３の前側周縁部表面（図１６中、上側周縁部表面）に当接され、該前枠３の前面部は、前面カバー部材７によってほぼ覆われ、遊技者側の前面側から見えなくなる。また、溝部６２を形成する傾斜面６２Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部の内側側縁部よりも少し外側方向の位置に対向する位置に形成される。また、補強リブ部３２の先端部（図１６中、上端面部）は、前面カバー部材７の裏側面の近傍まで延出されている。
【００５７】
従って、この補強リブ部３２によって、合成樹脂製の前枠３の剛性を確実に向上させることができると共に、該前面カバー部材７を閉じた場合には、この補強リブ部３２は前面カバー部材７によって覆われるため、パチンコ機６１の前面側周縁部に隙間などが発生することなく、見栄えを良くすることできる。
また、溝部６２の傾斜面６２Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部の内側側縁部と外側側縁部との間の位置に対向するように形成されているため、補強リブ部３２を前面カバー部材７の上辺部及び左右側辺部の内側側壁部により近づけて立設することが可能となる。このため、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入しても、このプラスチック板は遊技領域に達するためには、補強リブ部３２の外側の側壁部に当たった後、略直角に曲がり、更に、この補強リブ部３２を乗り越える必要があるため、薄いプラスチック板等の遊技領域への侵入を困難にすることが可能となる。
また、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入した場合には、プラスチック板の先端部は、溝部６２の垂直面６２Ａに当たった際に、パチンコ機６１の裏側方向に（矢印６３方向に）より曲がり易くなると共に、溝部６２内に進入した薄いプラスチック板は、この溝部６２の全長に渡っていずれの位置においても、垂直面６２Ａの奥側端縁部で断面略円弧状の傾斜面６２Ｂに押し付けられるように押圧された状態で該溝部６２の鋭角な底部で行き止まりとなり、薄いプラスチック板などの遊技領域への侵入を極めて困難にすることが可能となる。
【００５８】
ここで、垂直面６２Ａは、第１壁面として機能する。また、傾斜面６２Ｂは、第２壁面として機能する。
【００５９】
（第６実施形態）
次に、第６実施形態に係るパチンコ機について図１７に基づいて説明する。尚、上記第３実施形態に係るパチンコ機４１と同一符号は、上記第３実施形態に係るパチンコ機４１と同一あるいは相当部分を示すものである。
この第６実施形態に係るパチンコ機の概略構成は、第３実施形態に係るパチンコ機４１の構成とほぼ同じ構成である。但し、第６実施形態に係るパチンコ機の溝部の構成は、第３実施形態に係るパチンコ機４１の溝部４３の構成と異なっている。
【００６０】
図１７に示すように、第６実施形態に係るパチンコ機７１の概略構成は、上記第３実施形態に係るパチンコ機４１とほぼ同じ概略構成である（図１０乃至図１２参照）。但し、図１６に示すように、補強リブ部４２の外側側壁部４２Ｂの基端部に沿って形成される溝部７２は、前枠３の表面部に略垂直な垂直面７２Ａと、この垂直面７２Ａのパチンコ機７１の裏側方向（図１７中、下側方向）端縁部から、鋭角を形成して外側方向（図１７中、右側上方向）に延出される断面略円弧状の傾斜面７２Ｂと、から構成されている。また、この傾斜面７２Ｂの前枠３の表面側端縁部は、前面カバー部材７の前枠３の周縁表面部に対向する裏側端面内に対向するように形成されている。これにより、パチンコ機７１の前面カバー部材７を閉じた状態では、該前面カバー部材７の上辺部及び左右側辺部の後側端面部（図１７中、下側端面部）が前枠３の前側周縁部表面（図１７中、上側周縁部表面）に当接され、該前枠３の前面部は、前面カバー部材７によってほぼ覆われ、遊技者側の前面側から見えなくなる。また、溝部７２を形成する傾斜面７２Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部の内側側縁部よりも少し外側方向の位置に対向する位置に形成される。また、補強リブ部４２の先端部（図１７中、上端面部）は、前面カバー部材７の裏側面の近傍まで延出されている。
また、前面カバー部材７の上辺部及び左右側辺部の溝部７２に対向する内側周縁部には、案内リブ部４４が該溝部７２の全長に渡って略垂直外側方向（図１７中、下側方向）に突き出すように直線状に形成されている。そして、前面カバー部材７を閉じた際には、この案内リブ部４４の上端部は、溝部７２内に挿入され、該溝部７２を構成する傾斜面７２Ｂの近傍に位置するように形成されている。
【００６１】
従って、この補強リブ部４２によって、合成樹脂製の前枠３の剛性を確実に向上させることができると共に、該前面カバー部材７を閉じた場合には、この補強リブ部４２及び溝部７２は前面カバー部材７によって覆われるため、パチンコ機７１の前面側周縁部に隙間などが発生することなく、見栄えを良くすることできる。
また、溝部７２の傾斜面７２Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部の内側側縁部と外側側縁部との間の位置に対向するように形成されているため、補強リブ部４２を前面カバー部材７の上辺部及び左右側辺部の内側側壁部により近づけて立設することが可能となる。このため、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入しても、このプラスチック板は遊技領域に達するためには、補強リブ部４２の外側の側壁部に当たった後、略直角に曲がり、更に、この補強リブ部４２を乗り越える必要があるため、薄いプラスチック板等の遊技領域への侵入を困難にすることが可能となる。
また、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入した場合には、プラスチック板の先端部は、該プラスチック板の先端部が前面カバー部材７の案内リブ部４４に当接して、該溝部７２の断面略円弧状の傾斜面７２Ｂに沿うように（矢印７３方向に）強制的に折り曲げられる。そして、プラスチック板が更に進入した場合には、この溝部７２の全長に渡っていずれの位置においても、垂直面７２Ａの奥側端縁部で断面略円弧状の傾斜面７２Ｂに押し付けられるように押圧された状態で該溝部７２の鋭角な底部で行き止まりとなり、補強リブ部４２を乗り越えて、遊技領域方向に侵入できなくなる。また、案内リブ部４４の高さ寸法が低くても、プラスチック板の片側表面部が、溝部７２の開口部でこの案内リブ部４４に当接するため、溝部７２の垂直面７２Ａに沿って裏側方向に強制的に曲げられつつ溝部７２内に進入させられて、該溝部７２の鋭角な底部で行き止まりとなり、薄いプラスチック板などの遊技領域への侵入を極めて困難にすることが可能となる。
【００６２】
ここで、垂直面７２Ａは、第１壁面として機能する。また、傾斜面７２Ｂは、第２壁面として機能する。

（第７実施形態）
次に、第７実施形態に係るパチンコ機について図１８に基づいて説明する。尚、上記第１実施形態に係るパチンコ機１と同一符号は、上記第１実施形態に係るパチンコ機１と同一あるいは相当部分を示すものである。
この第７実施形態に係るパチンコ機の概略構成は、第１実施形態に係るパチンコ機１の構成とほぼ同じ構成である。但し、第７実施形態に係るパチンコ機の溝部の構成は、第１実施形態に係るパチンコ機１の溝部２４の構成と異なっている。

図１８に示すように、第７実施形態に係るパチンコ機８１の概略構成は、上記第１実施形態に係るパチンコ機１とほぼ同じ概略構成である（図１乃至図３参照）。但し、図１８に示すように、補強リブ部２３の外側側壁部２３Ａの基端部には、溝部８２が形成されている。この溝部８２は、前枠３の表面部に略垂直な垂直面よりも内側方向（図１８中、左側方向）に傾斜した壁面８２Ａと、この壁面８２Ａの裏側方向（図１８中、下側方向）端縁部から、鋭角を形成して外側方向（図１８中、右側上方向）に延出される平面状の傾斜面８２Ｂと、から構成されている。また、この傾斜面８２Ｂの前枠３の表面側端縁部は、前面カバー部材７の内側側壁部よりも内側に位置するように形成されている。これにより、パチンコ機８１の前面カバー部材７を閉じた状態では、該前面カバー部材７の上辺部及び左右側辺部の後側端面部（図１８中、下側端面部）が前枠３の前側周縁部表面（図１８中、上側周縁部表面）に当接され、該前枠３の前面部は、前面カバー部材７によってほぼ覆われ、遊技者側の前面側から見えなくなる。また、溝部８２を形成する傾斜面８２Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部よりも少し内側になる位置に形成されている。また、補強リブ部２３の先端部（図１８中、上端面部）は、前面カバー部材７の裏側面の近傍まで延出されている。
【００６５】
従って、この補強リブ部２３によって、合成樹脂製の前枠３の剛性を確実に向上させることができると共に、該前面カバー部材７を閉じた場合には、この補強リブ部２３及び溝部８２は前面カバー部材７によって覆われるため、パチンコ機８１の前面側周縁部に隙間などが発生することなく、見栄えを良くすることできる。
また、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入しても、このプラスチック板は遊技領域に達するためには、補強リブ部２３の外側の側壁部に当たった後、略直角に曲がり、更に、この補強リブ部２３を乗り越える必要があるため、薄いプラスチック板等の遊技領域への侵入を極めて困難にすることが可能となる。また、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入した場合に、このプラスチック板が補強リブ部２３の外側側壁部２３Ａに当たってパチンコ機８１の後側方向に（矢印８３方向に）曲がった時は、この外側側壁部２３Ａの基端部に沿って形成される溝部８２の壁面８２Ａに沿って傾斜面８２Ｂに沿うように溝部８２内に進入するため、該溝部８２の鋭角な底部で行き止まりとなり、薄いプラスチック板などの遊技領域への侵入を更に極めて困難にすることが可能となる。
【００６６】
ここで、壁面８２Ａは、第１壁面として機能する。また、傾斜面８２Ｂは、第２壁面として機能する。
【００６７】
尚、傾斜面８２Ｂの前枠３の表面側方向の端縁部に断面略円弧状の円弧部（例えば、図１５中、円弧部５２Ｃに相当する。）を形成してもよい。これにより、前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入しても、このプラスチック板が補強リブ部２３の外側側壁部２３Ａに当たった際に、傾斜面８２Ｂの前枠３の表面側方向の端縁部の円弧部に沿ってパチンコ機８１の後側方向に（矢印８３方向に）曲がり易くなり、この外側側壁部２３Ａの基端部に沿って形成される溝部８２の壁面８２Ａに沿って傾斜面８２Ｂに沿うように溝部８２内に進入する可能性を高くすることができると共に、該溝部８２内に進入した場合には、行き止まりとなり、薄いプラスチック板などの遊技領域への侵入を更に極めて困難にすることが可能となる。
ここで、壁面８２Ａは、第１壁面として機能する。また、傾斜面８２Ｂ及び該傾斜面８２Ｂの前枠３の表面側方向の端縁部の断面略円弧状の円弧部は、第２壁面を構成する。
【００６８】
（第８実施形態）
次に、第８実施形態に係るパチンコ機について図１９に基づいて説明する。尚、上記第２実施形態に係るパチンコ機３１と同一符号は、上記第２実施形態に係るパチンコ機３１と同一あるいは相当部分を示すものである。
この第８実施形態に係るパチンコ機の概略構成は、第２実施形態に係るパチンコ機３１の構成とほぼ同じ構成である。但し、第８実施形態に係るパチンコ機の溝部の構成は、第２実施形態に係るパチンコ機３１の溝部３３の構成と異なっている。
【００６９】
図１９に示すように、第８実施形態に係るパチンコ機９１の概略構成は、上記第２実施形態に係るパチンコ機３１とほぼ同じ概略構成である（図６及び図７参照）。但し、図１９に示すように、補強リブ部３２の外側側壁部３２Ｂの基端部に沿って形成される溝部９２は、前枠３の表面部に略垂直な垂直面よりも内側方向（図１９中、左側方向）に傾斜した壁面９２Ａと、この壁面９２Ａの裏側方向（図１９中、下側方向）端縁部から、鋭角を形成して外側方向（図１９中、右側上方向）に延出される平面状の傾斜面９２Ｂと、から構成されている。また、この傾斜面９２Ｂの前枠３の表面側端縁部は、前面カバー部材７の前枠３の周縁表面部に対向する裏側端面内に対向するように形成されている。これにより、パチンコ機９１の前面カバー部材７を閉じた状態では、該前面カバー部材７の上辺部及び左右側辺部の後側端面部（図１９中、下側端面部）が前枠３の前側周縁部表面（図１９中、上側周縁部表面）に当接され、該前枠３の前面部は、前面カバー部材７によってほぼ覆われ、遊技者側の前面側から見えなくなる。また、溝部９２を形成する傾斜面９２Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部の内側側縁部よりも少し外側方向の位置に対向する位置に形成される。また、補強リブ部３２の先端部（図１９中、上端面部）は、前面カバー部材７の裏側面の近傍まで延出されている。
【００７０】
従って、この補強リブ部３２によって、合成樹脂製の前枠３の剛性を確実に向上させることができると共に、該前面カバー部材７を閉じた場合には、この補強リブ部３２は前面カバー部材７によって覆われるため、パチンコ機９１の前面側周縁部に隙間などが発生することなく、見栄えを良くすることできる。
また、溝部９２の傾斜面９２Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部の内側側縁部と外側側縁部との間の位置に対向するように形成されているため、補強リブ部３２を前面カバー部材７の上辺部及び左右側辺部の内側側壁部により近づけて立設することが可能となる。このため、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入しても、このプラスチック板は遊技領域に達するためには、補強リブ部３２の外側の側壁部に当たった後、略直角に曲がり、更に、この補強リブ部３２を乗り越える必要があるため、薄いプラスチック板等の遊技領域への侵入を困難にすることが可能となる。
また、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入した場合には、プラスチック板の先端部は、溝部９２の壁面９２Ａに当たった際に、パチンコ機９１の裏側方向に（矢印９３方向に）より曲がり易くなる。そして、このプラスチック板が補強リブ部２３の外側側壁部２３Ａに当たってパチンコ機９１の後側方向に（矢印９３方向に）曲がった場合には、このプラスチック板は、溝部９２の壁面９２Ａに沿って傾斜面９２Ｂに沿うように溝部９２内に進入するため、該溝部９２の鋭角な底部で行き止まりとなり、薄いプラスチック板などの遊技領域への侵入を更に極めて困難にすることが可能となる。
【００７１】
ここで、垂直面９２Ａは、第１壁面として機能する。また、傾斜面９２Ｂは、第２壁面として機能する。
【００７２】
尚、平面状の傾斜面９２Ｂを壁面９２Ａ側に突き出る断面略円弧状の傾斜面（例えば、図１６中、傾斜面６２Ｂに相当する。）に形成してもよい。これにより、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入した場合には、プラスチック板の先端部は、溝部９２の壁面９２Ａに当たった際に、パチンコ機９１の裏側方向に（矢印９３方向に）より曲がり易くなると共に、溝部９２内に進入した薄いプラスチック板は、この溝部９２の全長に渡っていずれの位置においても、壁面９２Ａの奥側端縁部で断面略円弧状の傾斜面に押し付けられるように押圧された状態で該溝部９２の鋭角な底部で行き止まりとなり、薄いプラスチック板などの遊技領域への侵入を極めて困難にすることが可能となる。
ここで、壁面９２Ａは、第１壁面として機能する。また、壁面９２Ａ側に突き出る断面略円弧状の傾斜面は、第２壁面として機能する。
【００７３】
（第９実施形態）
次に、第９実施形態に係るパチンコ機について図２０に基づいて説明する。尚、上記第３実施形態に係るパチンコ機４１と同一符号は、上記第３実施形態に係るパチンコ機４１と同一あるいは相当部分を示すものである。
この第９実施形態に係るパチンコ機の概略構成は、第３実施形態に係るパチンコ機４１の構成とほぼ同じ構成である。但し、第９実施形態に係るパチンコ機の溝部の構成は、第３実施形態に係るパチンコ機４１の溝部４３の構成と異なっている。
【００７４】
図２０に示すように、第９実施形態に係るパチンコ機１０１の概略構成は、上記第３実施形態に係るパチンコ機４１とほぼ同じ概略構成である（図１０乃至図１２参照）。但し、図２０に示すように、補強リブ部４２の外側側壁部４２Ｂの基端部に沿って形成される溝部１０２は、前枠３の表面部に略垂直な垂直面よりも内側方向（図２０中、左側方向）に傾斜した壁面１０２Ａと、この壁面１０２Ａの裏側方向（図２０中、下側方向）端縁部から、鋭角を形成して外側方向（図２０中、右側上方向）に延出される平面状の傾斜面１０２Ｂと、から構成されている。また、この傾斜面１０２Ｂの前枠３の表面側端縁部は、前面カバー部材７の前枠３の周縁表面部に対向する裏側端面内に対向するように形成されている。これにより、パチンコ機１０１の前面カバー部材７を閉じた状態では、該前面カバー部材７の上辺部及び左右側辺部の後側端面部（図２０中、下側端面部）が前枠３の前側周縁部表面（図２０中、上側周縁部表面）に当接され、該前枠３の前面部は、前面カバー部材７によってほぼ覆われ、遊技者側の前面側から見えなくなる。また、溝部１０２を形成する傾斜面１０２Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部の内側側縁部よりも少し外側方向の位置に対向する位置に形成される。また、補強リブ部４２の先端部（図２０中、上端面部）は、前面カバー部材７の裏側面の近傍まで延出されている。
また、前面カバー部材７の上辺部及び左右側辺部の溝部１０２に対向する内側周縁部には、案内リブ部４４が該溝部１０２の全長に渡って略垂直外側方向（図２０中、下側方向）に突き出すように直線状に形成されている。そして、前面カバー部材７を閉じた際には、この案内リブ部４４の上端部は、溝部１０２内に挿入され、該溝部１０２を構成する傾斜面１０２Ｂの近傍に位置するように形成されている。
【００７５】
従って、この補強リブ部４２によって、合成樹脂製の前枠３の剛性を確実に向上させることができると共に、該前面カバー部材７を閉じた場合には、この補強リブ部４２及び溝部１０２は前面カバー部材７によって覆われるため、パチンコ機１０１の前面側周縁部に隙間などが発生することなく、見栄えを良くすることできる。
また、溝部１０２の傾斜面１０２Ｂの前枠３の表面側端縁部は、前面カバー部材７の上辺部及び左右側辺部の後側端面部の内側側縁部と外側側縁部との間の位置に対向するように形成されているため、補強リブ部４２を前面カバー部材７の上辺部及び左右側辺部の内側側壁部により近づけて立設することが可能となる。このため、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入しても、このプラスチック板は遊技領域に達するためには、補強リブ部４２の外側の側壁部に当たった後、略直角に曲がり、更に、この補強リブ部４２を乗り越える必要があるため、薄いプラスチック板等の遊技領域への侵入を困難にすることが可能となる。
また、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入した場合には、プラスチック板の先端部は、該プラスチック板の先端部が前面カバー部材７の案内リブ部４４に当接して、該溝部１０２の傾斜面１０２Ｂに沿うように（矢印１０３方向に）強制的に折り曲げられる。そして、プラスチック板が更に進入した場合には、この溝部１０２の全長に渡っていずれの位置においても、壁面１０２Ａの奥側端縁部で傾斜面１０２Ｂに押し付けられるように押圧された状態で該溝部１０２の鋭角な底部で行き止まりとなり、補強リブ部４２を乗り越えて、遊技領域方向に侵入できなくなる。また、案内リブ部４４の高さ寸法が低くても、プラスチック板の片側表面部が、溝部１０２の開口部でこの案内リブ部４４に当接するため、溝部１０２の壁面１０２Ａに沿って裏側方向に強制的に曲げられつつ溝部１０２内に進入させられて、該溝部１０２の鋭角な底部で行き止まりとなり、薄いプラスチック板などの遊技領域への侵入を極めて困難にすることが可能となる。
【００７６】
ここで、壁面１０２Ａは、第１壁面として機能する。また、傾斜面１０２Ｂは、第２壁面として機能する。
【００７７】
尚、平面状の傾斜面１０２Ｂを壁面１０２Ａ側に突き出る断面略円弧状の傾斜面（例えば、図１７中、傾斜面７２Ｂに相当する。）に形成してもよい。これにより、合成樹脂製の前枠３と前面カバー部材７の側端面との間の隙間から薄いプラスチック板等を挿入した場合には、プラスチック板の先端部は、前面カバー部材７の案内リブ部４４に当たった際に、パチンコ機１０１の裏側方向に（矢印１０３方向に）より曲がり易くなると共に、溝部１０２内に進入した薄いプラスチック板は、この溝部１０２の全長に渡っていずれの位置においても、壁面１０２Ａの奥側端縁部で断面略円弧状の傾斜面に押し付けられるように押圧された状態で該溝部１０２の鋭角な底部で行き止まりとなり、薄いプラスチック板などの遊技領域への侵入を極めて困難にすることが可能となる。
ここで、壁面１０２Ａは、第１壁面として機能する。また、壁面１０２Ａ側に突き出る断面略円弧状の傾斜面は、第２壁面として機能する。
【００７８】
また、本発明は、前記第１実施形態乃至第９実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内で種々の改良、変形が可能であることは勿論である。
例えば、前記第１実施形態乃至第９実施形態では、各補強リブ部２３、３２、４２及び各溝部２４乃至１０２は、上ヒンジ４に対向する部分が一部途切れた形状に形成されているが、前面カバー部材７の内側側壁部の形状に合わせて連続した形状に形成してもよい。これにより、上ヒンジ４近傍の前面カバー部材７の側壁部と前枠３との隙間から薄いプラスチック板（例えば、厚さ寸法約０．５ｍｍのプラスチック板）等を挿入した場合においても、該プラスチック板等は、各補強リブ部２３、３２、４２に当接後、各溝部２４乃至１０２内に進入して、奥側で行き止まりとなり、上ヒンジ４近傍の前面カバー部材７の側壁部と前枠３との隙間から遊技領域方向への侵入を更に困難にすることができる。
【００７９】

また、請求項４に係る遊技機では、合成樹脂製の前枠と前面カバー部材の側端面との間の隙間から薄いプラスチック板等を挿入した場合に、このプラスチック板が補強リブ部の外側の側壁部に当たって遊技機の後側方向に曲がった時は、この側壁部の基端部に沿って前枠の表面部に略垂直な垂直面よりも内側方向に傾斜するように形成された第１壁面に沿って更にスムーズに溝部内に進入するため、薄いプラスチック板は、この第１壁面と鋭角をなす第２壁面とで形成される奥側端縁部で遊技機の裏側方向に押圧された状態で行き止まりとなり、遊技領域への侵入を更に極めて困難にすることが可能な遊技機を提供することができる。
【００８３】
また、請求項５に係る遊技機では、第２壁面は、第１壁面と外側方向に鋭角を形成する平面状の傾斜面であるため、溝部内に進入した薄いプラスチック板は、この溝部の全長に渡っていずれの位置においても、第１壁面の奥側端縁部で第２壁面側方向に押圧された状態で行き止まりとなり、遊技領域への侵入を更に極めて困難にすることが可能な遊技機を提供することができる。

【００８５】
また、請求項７に係る遊技機では、合成樹脂製の前枠と前面カバー部材の側端面との間の隙間から薄いプラスチック板等を挿入した場合に、第２壁面は、第１壁面側に突き出る断面略円弧状の傾斜面に形成されているため、この薄いプラスチック板の先端部が補強リブ部の外側の側壁部に当たった際に、遊技機の裏側方向により曲がり易くなると共に、溝部内に進入した薄いプラスチック板は、この溝部の全長に渡っていずれの位置においても、第１壁面の奥側端縁部で該第２壁面に押し付けられるように押圧された状態で行き止まりとなり、遊技領域への侵入を更に極めて困難にすることが可能な遊技機を提供することができる。

Is provided. Around the upper edge and the left and right edges of the opening 21, the reinforcing ribs 23 are formed so as to oppose substantially the entire length of the upper side and the left and right side walls of the front cover member 7. It is formed linearly so as to protrude substantially vertically outward from the surface portion. As will be described later, a groove 24 is formed at the base end of the outer side wall 23A of the reinforcing rib 23 (see FIG. 4). When the front cover member 7 is attached to the front side of the front frame 3 and closed as shown in FIG. 1, each of the reinforcing ribs 23 and the groove 24 is covered with the front cover member 7 (FIG. 5). reference).
[0028]
Next, the reinforcing ribs 23 and the grooves 24 formed on the front surface of the front frame 3 will be described with reference to FIG.
As shown in FIG. 4, the reinforcing rib portion 23 has a substantially rectangular side section and is integrally formed so as to protrude substantially vertically from the front surface portion of the front frame 3. The height of the reinforcing ribs 23 from the surface of the front frame 3 is such that the upper end face is located near the back side of the front cover member 7 and will hit the back side of the front cover member 7 as described later. It is not formed.
The groove 24 formed along the base end of the outer side wall 23A of the reinforcing rib 23 has a vertical surface 24A substantially perpendicular to the front surface of the front frame 3 and a back side direction of the vertical surface 24A (see FIG. 4 and a flat inclined surface 24B extending outward (toward the upper right in FIG. 4) at an acute angle from the edge. The front edge of the front surface 3 of the inclined surface 24B is formed so as to be located inside the inner side wall of the front cover member 7 as described later (see FIG. 5).
[0029]
Next, the reinforcing rib portion 23 and the groove portion 24 of the pachinko machine 1 with the front cover member 7 closed will be described with reference to FIG.
As shown in FIG. 5, in a state where the front cover member 7 of the pachinko machine 1 is closed, a rear end surface portion (a lower end surface portion in FIG. 5) of an upper side portion and left and right side portions of the front cover member 7 is closed. The front frame 3 is in contact with the front peripheral surface of the front frame 3 (the upper peripheral surface in FIG. 5), and the front surface of the front frame 3 is almost covered by the front cover member 7 and cannot be seen from the front side of the player. . The front edge of the front surface 3 of the inclined surface 24B forming the groove 24 is formed at a position slightly inside the upper edge of the front cover member 7 and the rear edge of the left and right sides. I have. Further, a tip end portion (an upper end surface portion in FIG. 5) of the reinforcing rib portion 23 extends to near the rear side surface of the front cover member 7.
Thus, for example, when a thin plastic plate (for example, a plastic plate having a thickness of about 0.5 mm) is inserted through a gap between the side wall of the front cover member 7 and the front frame 3, the tip of the plastic plate is inserted. Is bent along the vertical surface 24A of the groove 24 in the rearward direction (downward direction in FIG. 5) after entering the groove 24 in the direction of arrow 28. As a result, a dead end is formed on the deep side of the groove 24 formed by the vertical surface 23A and the inclined surface 24B, and the vehicle cannot cross the reinforcement rib 23 and enter the game area direction (left direction in FIG. 5).
[0030]
Here, the vertical surface 24A functions as a first wall surface. The inclined surface 24B functions as a second wall surface.
[0031]
As described above, in the pachinko machine 1 according to the first embodiment, when the front cover member 7 is closed, the front side of the inner wall surface of the front cover member 7 Reinforcing ribs 23 are provided upright so as to face substantially the entire length of the left and right sides.

A groove 24 is formed, which is formed from an inclined surface 24B extending outward. The front edge of the front surface 3 of the inclined surface 24 </ b> B is formed so as to be located inside the inner side wall of the front cover member 7.
[0032]
Therefore, the rigidity of the front frame 3 made of synthetic resin can be reliably improved by the reinforcing ribs 23, and when the front cover member 7 is closed, the reinforcing ribs 23 and the groove 24 are formed on the front surface. Since the pachinko machine 1 is covered by the cover member 7, the appearance can be improved without generating a gap or the like at the peripheral portion on the front side of the pachinko machine 1.
Even if a thin plastic plate or the like is inserted from the gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the plastic plate does not reach the game area in order to reach the game area. After hitting the outer side wall, it is necessary to bend at a substantially right angle and to get over the reinforcing ribs 23, making it extremely difficult to invade a thin plastic plate or the like into the game area. Further, when a thin plastic plate or the like is inserted from a gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the plastic plate hits the outer side wall 23 </ b> A of the reinforcing rib 23 and the pachinko machine 1. When bent in the rearward direction, the groove 24 formed along the base end of the outer side wall 23A follows the inclined surface 24B along the vertical surface 24A substantially perpendicular to the surface of the front frame 3. As described above, since the vehicle enters the groove 24, a dead end occurs, and it is possible to make it extremely difficult to enter a game area such as a thin plastic plate.

However, the configuration of the reinforcing ribs and the grooves formed on the front surface of the synthetic resin front frame of the pachinko machine according to the second embodiment is the same as that of the pachinko machine 1 according to the first embodiment, as described later. It is different from the configuration of the groove 23 and the groove 24.
[0034]
As shown in FIGS. 6 and 7, the schematic configuration of the pachinko machine 31 according to the second embodiment is substantially the same as the pachinko machine 1 according to the first embodiment (see FIGS. 1 to 3). However, as shown in FIG. 7, reinforcing ribs 32 are provided on the upper edge and the left and right sides of the front cover member 7 at the upper edge and the left and right edges of the opening 21 provided at the approximate center of the front frame 3. The front frame 3 is formed linearly so as to protrude substantially vertically outward from the surface of the front frame 3 so as to face substantially the entire length of the side portion. As will be described later, a groove 33 is formed at the base end of the outer side wall 32A of the reinforcing rib 32 (see FIG. 8). Then, as shown in FIG. 6, when the front cover member 7 is attached to the front side of the front frame 3 and closed, the respective reinforcing ribs 32 and the grooves 33 are covered with the front cover member 7 (FIG. 9). reference).
[0035]
Next, the reinforcing ribs 32 and the grooves 33 formed on the front surface of the front frame 3 will be described with reference to FIG.
As shown in FIG. 8, the reinforcing rib portion 32 has a substantially rectangular side section and is integrally formed so as to protrude substantially perpendicularly from the front surface portion of the front frame 3. The height dimension of the reinforcing ribs 32 from the surface of the front frame 3 is such that the upper end face is located near the back side of the front cover member 7 and will hit the back side of the front cover member 7 as described later. It is not formed. A chamfered portion 32A is formed on the outer side edge of the upper end surface of the reinforcing rib portion 32. When the front cover member 7 is opened to the front side of the player, the back end surface of the front cover member 7 is formed. It is configured not to interfere with the unit. The reinforcing rib 32 is formed at a position slightly outward from the position where the reinforcing rib 23 formed on the periphery of the opening 21 of the pachinko machine 1 according to the first embodiment stands. I have. That is, when the front cover member 7 is closed, the reinforcing rib portion 32 is located closer to the back side wall surface of the front cover member 7 than the reinforcing rib portion 23 of the pachinko machine 1 according to the first embodiment. It is erected.
[0036]
The groove 33 formed along the base end of the outer side wall 32B of the reinforcing rib 32 has a vertical surface 33A substantially perpendicular to the surface of the front frame 3 and a back side direction of the vertical surface 33A (see FIG. 8, a downward inclined surface 33B that forms an acute angle and extends outward (upward on the right in FIG. 8) from the edge. The front edge of the front surface of the front frame 3 of the inclined surface 33B is formed so as to face the rear surface of the front frame 3 of the front cover member 7 which faces the peripheral surface of the front frame 3 as described later (see FIG. 4). (See FIG. 9).
[0037]
Next, the reinforcing rib 32 and the groove 33 in a state where the front cover member 7 of the pachinko machine 31 is closed will be described with reference to FIG.

The front frame 3 is brought into contact with the front peripheral surface of the front frame 3 (the upper peripheral surface in FIG. 9), and the front surface of the front frame 3 is almost covered by the front cover member 7 and becomes invisible from the front side of the player. . The front edge of the front surface 3 of the front surface 3 of the inclined surface 33B forming the groove 33 is formed by the inner side edge and the outer side edge of the upper edge of the front cover member 7 and the rear edge of the left and right sides. It is formed so that it may oppose the position between. For example, as shown in FIG. 9B, the front edge of the front surface 3 of the front surface 3 of the inclined surface 33B forming the groove 33 is formed by the upper edge of the front cover member 7 and the rear edge of the left and right edge. It is formed at a position facing a position slightly outward from the inner side edge. Further, a tip end portion (an upper end surface portion in FIG. 9) of the reinforcing rib portion 32 extends to near the rear side surface of the front cover member 7.
[0038]
Thereby, for example, when a thin plastic plate (for example, a plastic plate having a thickness of about 0.5 mm) or the like is inserted from the gap between the side wall portion of the front cover member 7 and the front frame 3, the tip of the plastic plate is inserted. The portion abuts against the outer side wall portion 32A of the reinforcing rib portion 32, and the opening of the groove portion 33 (the upper end portion in FIG. 9B) allows the one side surface of the plastic plate to be on the upper side and the left and right sides of the front cover member 7. It abuts on the inner side edge of the rear end surface of the side. Therefore, the front end of the plastic plate is easily bent in the rearward direction (downward direction in FIG. 9) along the vertical surface 33A of the groove 33. Then, as shown in FIG. 9 (B), it enters the groove 33 in the direction of the arrow 35, and reaches a dead end on the deep side of the groove 33 formed by the vertical surface 33A and the inclined surface 33B. And cannot enter the game area direction (left direction in FIG. 9).
[0039]
Here, the vertical surface 33A functions as a first wall surface. In addition, the inclined surface 33B functions as a second wall surface.
[0040]
As described above, in the pachinko machine 31 according to the second embodiment, when the front cover member 7 is closed, the upper edge of the inner wall surface of the front cover member 7 A reinforcing rib portion 32 is provided upright so as to oppose substantially the entire length of the left and right sides. The base end of the outer side wall portion 32B of the reinforcing rib portion 32 has a vertical surface 33A substantially perpendicular to the surface of the front frame 3 and an acute angle formed from the back side edge of the vertical surface 33A. A groove 33 composed of an inclined surface 33B extending outward is formed. The front edge of the front surface 3 of the inclined surface 33B is located between the inner edge and the outer edge of the upper edge of the front cover member 7 and the rear edge of the left and right edge. Is formed so as to oppose.
[0041]
Therefore, the rigidity of the synthetic resin front frame 3 can be reliably improved by the reinforcing ribs 32, and when the front cover member 7 is closed, the reinforcing ribs 32 are Therefore, the pachinko machine 31 can be improved in appearance without generating a gap or the like at the peripheral edge on the front side.
The front edge of the front surface 3 of the inclined surface 33B of the groove 33 is located between the inner edge and the outer edge of the rear edge of the upper edge of the front cover member 7 and the left and right edges. , The reinforcing ribs 32 can be erected closer to the inner side walls of the upper side and the left and right sides of the front cover member 7. For this reason, even if a thin plastic plate or the like is inserted through a gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, this plastic plate does not reach the game area without the reinforcing ribs 32. After hitting the outer side wall portion, it is necessary to bend at a substantially right angle and to get over the reinforcing rib portion 32, thereby making it difficult for the thin plastic plate or the like to enter the game area.
When a thin plastic plate or the like is inserted through a gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the tip of the plastic plate extends along the vertical surface 33 </ b> A of the groove 33. It is made to enter the groove 33 while being forcibly bent in the direction of the inclined surface 33B, and reaches a dead end at the sharp bottom of the groove 33, which makes it extremely difficult to enter a game area such as a thin plastic plate. Become.

The height dimension of the reinforcing ribs 42 from the surface of the front frame 3 is such that the upper end face is located near the back face of the front cover member 7 and will hit the back face of the front cover member 7 as described later. It is not formed. A chamfered portion 42A is formed on the outer side edge of the upper end surface of the reinforcing rib portion 42, and when the front cover member 7 is opened to the front side of the player, the back end surface of the front cover member 7 is formed. It is configured not to interfere with the unit. The reinforcing ribs 42 are formed at positions slightly outward from the positions where the reinforcing ribs 23 formed on the periphery of the opening 21 of the pachinko machine 1 according to the first embodiment are erected. I have. That is, when the front cover member 7 is closed, the reinforcing rib portion 42 is located closer to the back side wall surface of the front cover member 7 than the reinforcing rib portion 23 of the pachinko machine 1 according to the first embodiment. It is erected.
[0045]
A groove 43 formed along the base end of the outer side wall portion 42B of the reinforcing rib portion 42 has a vertical surface 43A substantially perpendicular to the front surface of the front frame 3 and a back side direction of the vertical surface 43A (see FIG. 13, a downward inclined surface 43B extending outwardly (upward on the right in FIG. 13) at an acute angle from the edge. In addition, the front edge of the front surface 3 of the inclined surface 43B is formed so as to face the inside of the rear surface facing the peripheral surface of the front frame 3 of the front cover member 7 (described later). See FIG. 14).
[0046]
Next, a schematic configuration of the reinforcing rib portion 42, the groove portion 43, and the guide rib portion 44 when the front cover member 7 of the pachinko machine 41 is closed will be described with reference to FIG.
As shown in FIG. 14, when the front cover member 7 of the pachinko machine 41 is closed, the rear side end portions of the upper side portion and the left and right side portions of the front cover member 7 (the lower side end portion in FIG. 14). The front frame 3 is in contact with the front peripheral surface of the front frame 3 (the upper peripheral surface in FIG. 14), and the front surface of the front frame 3 is almost covered by the front cover member 7 and cannot be seen from the front side of the player. . The front side edge of the front surface 3 of the inclined surface 43B forming the groove 43 is formed by the inner side edge and the outer side edge of the upper side and the left and right side of the front cover member 7. It is formed so that it may oppose the position between. For example, as shown in FIG. 14 (B), the front edge of the front surface 3 of the front surface 3 of the inclined surface 43 </ b> B forming the groove 43 is the rear edge of the upper edge of the front cover member 7 and the left and right edge. It is formed at a position facing a position slightly outward from the inner side edge. In addition, a tip end portion (an upper end surface portion in FIG. 14) of the reinforcing rib portion 42 extends to a vicinity of a back side surface of the front cover member 7.
Further, a guide rib portion 44 is provided on the inner peripheral edge portion facing the upper side portion and the left and right side side groove portions 43 of the front cover member 7 in a substantially vertical outward direction over the entire length of the groove portion 43 (the lower side in FIG. 14). Direction). When the front cover member 7 is closed, the upper end of the guide rib 44 is inserted into the groove 43 and is formed so as to be located near the inclined surface 43B constituting the groove 43. .
[0047]
Thereby, for example, when a thin plastic plate (for example, a plastic plate having a thickness of about 0.5 mm) or the like is inserted from the gap between the side wall portion of the front cover member 7 and the front frame 3, the tip of the plastic plate is inserted. The portion comes into contact with the guide rib portion 44 of the front cover member 7 and is bent rearward (downward in FIG. 14) along the inclined surface 43B of the groove portion 43, so that the vertical surface 43A of the groove portion 43 and the inclined surface are inclined. A dead end is formed on the inner side of the groove 43 formed by the groove 43B, and it is impossible to get over the reinforcing rib 42 and enter the game area direction (left direction in FIG. 14). Even if the height dimension of the guide rib portion 44 is small, one surface portion of the plastic plate abuts on the guide rib portion 44 at the opening of the groove portion 43 (the upper end portion in FIG. 14B). Therefore, the front end of the plastic plate is bent in the back side direction (downward direction in FIG. 14) along the vertical surface 43A of the groove 43. Then, as shown in FIG. 14 (B), it enters the groove 43 in the direction of arrow 45, and reaches a dead end on the deep side of the groove 43 formed by the vertical surface 43A and the inclined surface 43B, and the reinforcing rib portion 42 And cannot enter the game area direction (left direction in FIG. 14).
[0048]
Here, the vertical surface 43A functions as a first wall surface. In addition, the inclined surface 43B functions as a second wall surface.
[0049]
As described above, in the pachinko machine 41 according to the third embodiment, when the front cover member 7 is closed, the upper side of the inner wall surface of the front cover member 7 A reinforcing rib portion 42 is provided upright so as to oppose substantially the entire length of the left and right sides. The base end of the outer side wall 42B of the reinforcing rib 42 has a vertical surface 43A substantially perpendicular to the surface of the front frame 3 and an acute angle formed from the rear edge of the vertical surface 43A. A groove 43 composed of an inclined surface 43B extending outward is formed. The front edge of the front surface 3 of the inclined surface 43B is located between the inner edge and the outer edge of the upper edge of the front cover member 7 and the rear edge of the left and right edges. Is formed so as to oppose. In addition, a guide rib portion 44 is linearly formed on the inner peripheral portion of the front cover member 7 facing the upper side portion and the left and right side side portions of the groove portion 43 so as to protrude substantially vertically outward over the entire length of the groove portion 43. Is formed.
[0050]
Therefore, the rigidity of the front frame 3 made of synthetic resin can be reliably improved by the reinforcing ribs 42, and when the front cover member 7 is closed, the reinforcing ribs 42 and the groove 43 are formed on the front surface. Since the pachinko machine 41 is covered by the cover member 7, the appearance can be improved without generating a gap or the like at the peripheral portion on the front side of the pachinko machine 41.
Further, the front edge of the front surface 3 of the inclined surface 43B of the groove 43 is located between the inner edge and the outer edge of the rear edge of the upper edge and the right and left edge of the front cover member 7. , The reinforcing ribs 42 can be erected closer to the upper side and the inner side walls of the left and right sides of the front cover member 7. For this reason, even if a thin plastic plate or the like is inserted through a gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the plastic plate does not reach the game area without the reinforcing ribs 42. After hitting the outer side wall portion, it is necessary to bend at a substantially right angle and to get over the reinforcing rib portion 42, thereby making it difficult to enter a thin plastic plate or the like into the game area.
When a thin plastic plate or the like is inserted from the gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the front end of the plastic plate is replaced with the front cover. Abutting against the guide rib portion 44 of the member 7, it is bent rearward along the inclined surface 43 </ b> B of the groove 43, and reaches a dead end at the deep side of the groove 43 formed by the vertical surface 43 </ b> A and the inclined surface 43 </ b> B of the groove 43. As a result, it is impossible to get over the reinforcing rib portion 42 and enter the game area. Even if the height dimension of the guide rib portion 44 is low, one surface of the plastic plate abuts on the guide rib portion 44 at the opening of the groove portion 43, so that the back side direction along the vertical surface 43A of the groove portion 43 The groove 43 is forcibly bent into the groove 43, and reaches a dead end at the sharp bottom of the groove 43. This makes it extremely difficult to enter a game area such as a thin plastic plate.
[0051]
(Fourth embodiment)
Next, a pachinko machine according to a fourth embodiment will be described with reference to FIG. The same reference numerals as those of the pachinko machine 1 according to the first embodiment denote the same or corresponding parts as those of the pachinko machine 1 according to the first embodiment.
The schematic configuration of the pachinko machine according to the fourth embodiment is substantially the same as the configuration of the pachinko machine 1 according to the first embodiment. However, the configuration of the groove of the pachinko machine according to the fourth embodiment is different from the configuration of the groove 24 of the pachinko machine 1 according to the first embodiment.
[0052]
As shown in FIG. 15, the schematic configuration of the pachinko machine 51 according to the fourth embodiment is substantially the same as that of the pachinko machine 1 according to the first embodiment (see FIGS. 1 to 3). However, as shown in FIG. 15, a groove 52 is formed at the base end of the outer side wall 23 </ b> A of the reinforcing rib 23. The groove portion 52 forms an acute angle from a vertical surface 52A substantially perpendicular to the surface of the front frame 3 and an edge of the vertical surface 52A in the back side direction (downward direction in FIG. 15) in the outward direction (FIG. 15, a right side upward direction), a flat inclined surface 52B, and an arc portion 52C having a substantially arc-shaped cross section formed on the front edge of the front surface of the front surface 3 of the inclined surface 52B. It is configured. The front edge of the front frame 3 of the arc portion 52 </ b> C is formed so as to be located inside the inner side wall of the front cover member 7. Thus, when the front cover member 7 of the pachinko machine 51 is closed, the rear side end portions (the lower end surface portion in FIG. 15) of the upper side portion and the left and right side portions of the front cover member 7 are formed by the front frame 3. The front surface of the front frame 3 is almost covered by the front cover member 7 and is invisible from the front side of the player side. The front edge of the front frame 3 of the arc portion 52C forming the groove 52 is formed at a position slightly inside the upper edge of the front cover member 7 and the rear edge of the left and right sides. I have. In addition, a tip end portion (an upper end surface portion in FIG. 15) of the reinforcing rib portion 23 extends to near the rear side surface of the front cover member 7.
[0053]
Therefore, the rigidity of the front frame 3 made of synthetic resin can be reliably improved by the reinforcing ribs 23, and when the front cover member 7 is closed, the reinforcing ribs 23 and the groove 52 are formed on the front surface. Since the pachinko machine 51 is covered with the cover member 7, the appearance can be improved without generating a gap or the like at the peripheral portion on the front side of the pachinko machine 51.
Even if a thin plastic plate or the like is inserted from the gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the plastic plate does not reach the game area in order to reach the game area. After hitting the outer side wall, it is necessary to bend at a substantially right angle and to get over the reinforcing ribs 23, making it extremely difficult to invade a thin plastic plate or the like into the game area. Further, when a thin plastic plate or the like is inserted from a gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, when the plastic plate hits the outer side wall portion 23 </ b> A of the reinforcing rib portion 23. Then, the pachinko machine 51 easily bends in the rearward direction (in the direction of the arrow 53) along the arc portion 52C, and along the vertical surface 52A of the groove portion 52 formed along the base end portion of the outer side wall portion 23A. The likelihood of entry into the groove 52 along the inclined surface 52B can be increased, and when entering the groove 52, a dead end is reached, and entry into the game area such as a thin plastic plate is further reduced. It can be difficult.
[0054]
Here, the vertical surface 52A functions as a first wall surface. The inclined surface 52B and the arc portion 52C constitute a second wall surface.
[0055]
(Fifth embodiment)
Next, a pachinko machine according to a fifth embodiment will be described with reference to FIG. The same reference numerals as those of the pachinko machine 31 according to the second embodiment denote the same or corresponding parts as those of the pachinko machine 31 according to the second embodiment.
The schematic configuration of the pachinko machine according to the fifth embodiment is substantially the same as the configuration of the pachinko machine 31 according to the second embodiment. However, the configuration of the groove of the pachinko machine according to the fifth embodiment is different from the configuration of the groove 33 of the pachinko machine 31 according to the second embodiment.
[0056]
As shown in FIG. 16, the schematic configuration of the pachinko machine 61 according to the fifth embodiment is substantially the same as the pachinko machine 31 according to the second embodiment (see FIGS. 6 and 7). However, as shown in FIG. 16, the groove 62 formed along the base end of the outer side wall 32 </ b> B of the reinforcing rib 32 has a vertical surface 62 </ b> A substantially perpendicular to the surface of the front frame 3 and a vertical surface 62 </ b> A. A substantially arc-shaped inclined surface 62B extending in the outward direction (upper right side in FIG. 16) at an acute angle from the rear edge (lower direction in FIG. 16) of 62A. Have been. The front edge of the front surface 3 of the inclined surface 62B is formed so as to face the inside of the rear surface facing the peripheral surface of the front frame 3 of the front cover member 7. Thus, when the front cover member 7 of the pachinko machine 61 is closed, the rear side end portions (the lower end surface portion in FIG. 16) of the upper side portion and the left and right side portions of the front cover member 7 are formed by the front frame 3. The front surface of the front frame 3 is almost covered by the front cover member 7 and is invisible from the front side of the player side, in contact with the front peripheral surface (the upper peripheral surface in FIG. 16). Further, the front edge of the front surface 3 of the inclined surface 62B forming the groove 62 is slightly more outward than the inner side edges of the upper edge of the front cover member 7 and the rear edge of the left and right sides. It is formed at a position opposite to the position. In addition, a front end portion (an upper end surface portion in FIG. 16) of the reinforcing rib portion 32 extends to a vicinity of a rear side surface of the front cover member 7.
[0057]
Therefore, the rigidity of the synthetic resin front frame 3 can be reliably improved by the reinforcing ribs 32, and when the front cover member 7 is closed, the reinforcing ribs 32 are Therefore, the pachinko machine 61 can be improved in appearance without generating a gap or the like at the peripheral portion on the front side of the pachinko machine 61.
In addition, the front edge of the front surface 3 of the inclined surface 62B of the groove 62 is located between the inner side edge and the outer side edge of the upper edge of the front cover member 7 and the rear edge of the left and right sides. , The reinforcing ribs 32 can be erected closer to the inner side walls of the upper side and the left and right sides of the front cover member 7. For this reason, even if a thin plastic plate or the like is inserted through a gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, this plastic plate does not reach the game area without the reinforcing ribs 32. After hitting the outer side wall portion, it is necessary to bend at a substantially right angle and to get over the reinforcing rib portion 32, thereby making it difficult for the thin plastic plate or the like to enter the game area.
When a thin plastic plate or the like is inserted from a gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the tip of the plastic plate hits the vertical surface 62A of the groove 62. At this time, the pachinko machine 61 is more easily bent in the back side direction (in the direction of the arrow 63), and the thin plastic plate that has entered the groove 62 has the vertical surface 62A at any position over the entire length of the groove 62. In a state in which the groove is pressed so as to be pressed against the inclined surface 62B having a substantially arc-shaped cross section at the far side edge portion thereof, a dead end is formed at the sharp bottom of the groove portion 62, and it is extremely difficult to enter a game area such as a thin plastic plate. It is possible to do.
[0058]
Here, the vertical surface 62A functions as a first wall surface. In addition, the inclined surface 62B functions as a second wall surface.
[0059]
(Sixth embodiment)
Next, a pachinko machine according to a sixth embodiment will be described with reference to FIG. The same reference numerals as those of the pachinko machine 41 according to the third embodiment denote the same or corresponding parts as those of the pachinko machine 41 according to the third embodiment.
The schematic configuration of the pachinko machine according to the sixth embodiment is substantially the same as the configuration of the pachinko machine 41 according to the third embodiment. However, the configuration of the groove of the pachinko machine according to the sixth embodiment is different from the configuration of the groove 43 of the pachinko machine 41 according to the third embodiment.
[0060]
As shown in FIG. 17, the schematic configuration of the pachinko machine 71 according to the sixth embodiment is substantially the same as the pachinko machine 41 according to the third embodiment (see FIGS. 10 to 12). However, as shown in FIG. 16, the groove 72 formed along the base end of the outer side wall 42 </ b> B of the reinforcing rib 42 includes a vertical surface 72 </ b> A substantially perpendicular to the surface of the front frame 3 and this vertical surface 72 </ b> A. A slanted surface 72B having a substantially arc-shaped cross-section that forms an acute angle and extends outward (upward to the right in FIG. 17) from an edge of the back side (lower direction in FIG. 17) of the pachinko machine 71 of 72A. And is composed of The front edge of the front surface 3 of the inclined surface 72B is formed so as to face the rear end surface of the front cover member 7 which faces the peripheral surface of the front frame 3. Accordingly, when the front cover member 7 of the pachinko machine 71 is closed, the rear side end portions (the lower end surface portion in FIG. 17) of the upper side portion and the left and right side portions of the front cover member 7 are formed by the front frame 3. The front surface of the front frame 3 is almost covered by the front cover member 7 and is invisible from the front side of the player side, in contact with the front peripheral surface (the upper peripheral surface in FIG. 17). Also, the front edge of the front surface 3 of the inclined surface 72B forming the groove 72 is slightly more outward than the inner edge of the upper edge of the front cover member 7 and the rear edge of the left and right sides. It is formed at a position opposite to the position. Further, a tip end portion (upper end face portion in FIG. 17) of the reinforcing rib portion 42 extends to a vicinity of a back side surface of the front cover member 7.
Further, a guide rib portion 44 is provided on the inner peripheral edge portion facing the groove portion 72 on the upper side and the left and right side portions of the front cover member 7 in a substantially vertical outward direction over the entire length of the groove portion 72 (the lower side in FIG. 17). Direction). When the front cover member 7 is closed, the upper end of the guide rib 44 is inserted into the groove 72 and formed so as to be located near the inclined surface 72B constituting the groove 72. .
[0061]
Therefore, the rigidity of the front frame 3 made of synthetic resin can be reliably improved by the reinforcing ribs 42, and when the front cover member 7 is closed, the reinforcing ribs 42 and the groove 72 are formed on the front surface. Since the pachinko machine 71 is covered with the cover member 7, the pachinko machine 71 can be improved in appearance without generating a gap or the like at the peripheral portion on the front side.
In addition, the front edge of the front surface 3 of the inclined surface 72B of the groove 72 is located between the inner edge and the outer edge of the upper edge of the front cover member 7 and the rear edge of the left and right edge. , The reinforcing ribs 42 can be erected closer to the upper side and the inner side walls of the left and right sides of the front cover member 7. For this reason, even if a thin plastic plate or the like is inserted through a gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the plastic plate does not reach the game area without the reinforcing ribs 42. After hitting the outer side wall portion, it is necessary to bend at a substantially right angle and to get over the reinforcing rib portion 42, thereby making it difficult to enter a thin plastic plate or the like into the game area.
When a thin plastic plate or the like is inserted from the gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the front end of the plastic plate is replaced with the front cover. The groove 72 is forcibly bent (in the direction of the arrow 73) so as to abut on the guide rib portion 44 of the member 7 and to follow the inclined surface 72B of the groove portion 72 having a substantially arc-shaped cross section. When the plastic plate further enters, it is pressed at any position over the entire length of the groove 72 so as to be pressed against the inclined surface 72B having a substantially arc-shaped cross section at the far end of the vertical surface 72A. In this state, a dead end occurs at the sharp bottom of the groove 72, and the vehicle cannot get over the reinforcement rib 42 and enter the game area. Even if the height of the guide ribs 44 is small, the one side surface of the plastic plate abuts on the guide ribs 44 at the opening of the groove 72, so that the back side along the vertical surface 72 </ b> A of the groove 72. The groove 72 is forced into the groove 72 while being forced to bend, and reaches a dead end at the sharp bottom of the groove 72, making it extremely difficult to enter a game area such as a thin plastic plate.
[0062]
Here, the vertical surface 72A functions as a first wall surface. The inclined surface 72B functions as a second wall surface.
[0063]
(Seventh embodiment)
Next, a pachinko machine according to a seventh embodiment will be described with reference to FIG. The same reference numerals as those of the pachinko machine 1 according to the first embodiment denote the same or corresponding parts as those of the pachinko machine 1 according to the first embodiment.
The schematic configuration of the pachinko machine according to the seventh embodiment is substantially the same as the configuration of the pachinko machine 1 according to the first embodiment. However, the configuration of the groove of the pachinko machine according to the seventh embodiment is different from the configuration of the groove 24 of the pachinko machine 1 according to the first embodiment.
[0064]
As shown in FIG. 18, the schematic configuration of the pachinko machine 81 according to the seventh embodiment is substantially the same as the pachinko machine 1 according to the first embodiment (see FIGS. 1 to 3). However, as shown in FIG. 18, a groove 82 is formed at the base end of the outer side wall 23 </ b> A of the reinforcing rib 23. The groove 82 has a wall surface 82A inclined inward (leftward in FIG. 18) from a vertical surface substantially perpendicular to the surface of the front frame 3, and a back side direction (downward in FIG. 18) of the wall surface 82A. And a flat inclined surface 82B extending from the edge to the outside (upward on the right side in FIG. 18) at an acute angle. The front edge of the front surface 3 of the inclined surface 82 </ b> B is formed so as to be located inside the inner side wall of the front cover member 7. Thereby, when the front cover member 7 of the pachinko machine 81 is closed, the rear side end portions (the lower end surface portion in FIG. 18) of the upper side portion and the left and right side portions of the front cover member 7 are formed by the front frame 3. The front surface of the front frame 3 is almost covered by the front cover member 7 and is invisible from the front side of the player side. The front edge of the front surface 3 of the inclined surface 82B forming the groove 82 is formed at a position slightly inside the upper edge of the front cover member 7 and the rear edge of the left and right sides. I have. In addition, a tip end portion (an upper end surface portion in FIG. 18) of the reinforcing rib portion 23 extends to near the rear side surface of the front cover member 7.
[0065]
Therefore, the rigidity of the front frame 3 made of synthetic resin can be reliably improved by the reinforcing ribs 23, and when the front cover member 7 is closed, the reinforcing ribs 23 and the groove 82 are formed on the front surface. Since the pachinko machine 81 is covered with the cover member 7, the appearance can be improved without generating a gap or the like at the peripheral portion on the front side of the pachinko machine 81.
Even if a thin plastic plate or the like is inserted from the gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the plastic plate does not reach the game area in order to reach the game area. After hitting the outer side wall, it is necessary to bend at a substantially right angle and to get over the reinforcing ribs 23, making it extremely difficult to invade a thin plastic plate or the like into the game area. When a thin plastic plate or the like is inserted through a gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the plastic plate hits the outer side wall 23 </ b> A of the reinforcing rib 23 and the pachinko machine 81. When bent in the rearward direction (in the direction of arrow 83), the groove 82 is formed along the inclined surface 82B along the wall surface 82A of the groove 82 formed along the base end of the outer side wall 23A. As a result, a dead end is formed at the sharp bottom of the groove 82, and it is possible to make it extremely difficult to enter a game area such as a thin plastic plate.
[0066]
Here, the wall surface 82A functions as a first wall surface. The inclined surface 82B functions as a second wall surface.
[0067]
Note that an arc portion having a substantially arc-shaped cross section (e.g., corresponding to the arc portion 52C in FIG. 15) may be formed at the edge of the inclined surface 82B in the front surface direction of the front frame 3. Thus, even if a thin plastic plate or the like is inserted from the gap between the front frame 3 and the side end surface of the front cover member 7, when this plastic plate hits the outer side wall portion 23A of the reinforcing rib portion 23, it is inclined. The pachinko machine 81 easily bends in the rearward direction (in the direction of arrow 83) along the arc of the front edge of the front frame 3 of the surface 82B in the front side direction, and along the base end of the outer side wall 23A. It is possible to increase the possibility of entering the groove 82 along the inclined surface 82B along the wall surface 82A of the formed groove 82, and when entering the groove 82, a dead end occurs and the thin plastic It is possible to make it extremely difficult to enter a game area such as a board.
Here, the wall surface 82A functions as a first wall surface. Further, an arc portion having a substantially arc-shaped cross section at the inclined surface 82B and the edge of the front surface 3 of the front surface 3 of the inclined surface 82B constitutes a second wall surface.
[0068]

The same reference numerals as those of the pachinko machine 31 according to the second embodiment denote the same or corresponding parts as those of the pachinko machine 31 according to the second embodiment.
The schematic configuration of the pachinko machine according to the eighth embodiment is substantially the same as the configuration of the pachinko machine 31 according to the second embodiment. However, the configuration of the groove of the pachinko machine according to the eighth embodiment is different from the configuration of the groove 33 of the pachinko machine 31 according to the second embodiment.
[0069]
As shown in FIG. 19, the schematic configuration of the pachinko machine 91 according to the eighth embodiment is substantially the same as the pachinko machine 31 according to the second embodiment (see FIGS. 6 and 7). However, as shown in FIG. 19, the groove 92 formed along the base end of the outer side wall 32 </ b> B of the reinforcing rib 32 is inward (in FIG. 19) from a vertical plane substantially perpendicular to the surface of the front frame 3. 19, a wall surface 92A inclined to the left (in the left direction) and an edge of the wall 92A in the rear direction (the lower direction in FIG. 19) forms an acute angle in the outward direction (the upper right direction in FIG. 19). And a planar inclined surface 92B extending therefrom. The front edge of the front surface 3 of the inclined surface 92 </ b> B is formed so as to face the inside of the rear surface facing the peripheral surface of the front frame 3 of the front cover member 7. Thus, when the front cover member 7 of the pachinko machine 91 is closed, the rear edge of the upper edge and the left and right edges of the front cover member 7 (the lower edge in FIG. The front surface of the front frame 3 is almost covered by the front cover member 7 and is invisible from the front side of the player side. The front edge of the front surface 3 of the front surface 3 of the inclined surface 92B forming the groove 92 is slightly more outward than the inner edges of the upper edge of the front cover member 7 and the rear edge of the left and right sides. It is formed at a position opposite to the position. Further, a tip end portion (an upper end surface portion in FIG. 19) of the reinforcing rib portion 32 extends to near the rear side surface of the front cover member 7.

(Ninth embodiment)
Next, a pachinko machine according to a ninth embodiment will be described with reference to FIG. The same reference numerals as those of the pachinko machine 41 according to the third embodiment denote the same or corresponding parts as those of the pachinko machine 41 according to the third embodiment.
The schematic configuration of the pachinko machine according to the ninth embodiment is substantially the same as the configuration of the pachinko machine 41 according to the third embodiment. However, the configuration of the groove of the pachinko machine according to the ninth embodiment is different from the configuration of the groove 43 of the pachinko machine 41 according to the third embodiment.
[0074]
As shown in FIG. 20, the schematic configuration of the pachinko machine 101 according to the ninth embodiment is substantially the same as that of the pachinko machine 41 according to the third embodiment (see FIGS. 10 to 12). However, as shown in FIG. 20, the groove 102 formed along the base end of the outer side wall 42 </ b> B of the reinforcing rib 42 is inward (in FIG. 20) from a vertical plane substantially perpendicular to the surface of the front frame 3. 20, a wall surface 102A inclined to the left (in the left direction) and an edge of the rear surface of the wall 102A (in the downward direction in FIG. 20) forming an acute angle in an outward direction (in the upper right direction in FIG. 20). And a planar inclined surface 102B extending therefrom. Further, the front edge of the front surface 3 of the inclined surface 102B is formed so as to face the rear end surface of the front cover member 7 which faces the peripheral surface of the front frame 3. Thus, when the front cover member 7 of the pachinko machine 101 is closed, the rear edge of the upper edge of the front cover member 7 and the left and right side edges (the lower edge in FIG. 20) of the front frame 3 The front surface of the front frame 3 is almost covered by the front cover member 7 and is invisible from the front side of the player side. Also, the front edge of the front surface 3 of the inclined surface 102B forming the groove 102 is slightly more outwardly than the inner edge of the upper edge of the front cover member 7 and the rear edge of the left and right sides. It is formed at a position opposite to the position. Further, a tip end portion (upper end face portion in FIG. 20) of the reinforcing rib portion 42 extends to a vicinity of a back side surface of the front cover member 7.
In addition, a guide rib portion 44 is provided on the inner peripheral portion facing the groove portion 102 on the upper side portion and the left and right side portions of the front cover member 7 in a substantially vertical outward direction over the entire length of the groove portion 102 (the lower side in FIG. 20).

Therefore, the rigidity of the front frame 3 made of synthetic resin can be reliably improved by the reinforcing ribs 42, and when the front cover member 7 is closed, the reinforcing ribs 42 and the groove 102 can be attached to the front surface. Since the pachinko machine 101 is covered with the cover member 7, the pachinko machine 101 can be improved in appearance without generating a gap or the like at the peripheral edge on the front side.
The front edge of the front surface 3 of the inclined surface 102B of the groove 102 is located between the inner edge and the outer edge of the rear edge of the upper edge of the front cover member 7 and the right and left edges. , The reinforcing ribs 42 can be erected closer to the upper side and the inner side walls of the left and right sides of the front cover member 7. For this reason, even if a thin plastic plate or the like is inserted through a gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the plastic plate does not reach the game area without the reinforcing ribs 42. After hitting the outer side wall portion, it is necessary to bend at a substantially right angle and to get over the reinforcing rib portion 42, thereby making it difficult to enter a thin plastic plate or the like into the game area.
When a thin plastic plate or the like is inserted from the gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the front end of the plastic plate is replaced with the front cover. The member 7 comes into contact with the guide rib portion 44 and is forcibly bent (in the direction of the arrow 103) along the inclined surface 102B of the groove portion 102. Then, when the plastic plate further enters, at any position over the entire length of the groove portion 102, the groove portion is pressed in such a manner as to be pressed against the inclined surface 102B at the rear edge of the wall surface 102A. A dead end occurs at the sharp bottom of 102, and it is impossible to get over the reinforcing ribs 42 and enter the game area. Even if the height of the guide ribs 44 is low, one surface of the plastic plate abuts on the guide ribs 44 at the opening of the groove 102, so that the surface of the plastic plate extends rearward along the wall 102A of the groove 102. It is forced into the groove 102 while being bent, and reaches a dead end at the sharp bottom of the groove 102, making it extremely difficult to enter a game area such as a thin plastic plate.
[0076]
Here, the wall surface 102A functions as a first wall surface. In addition, the inclined surface 102B functions as a second wall surface.
[0077]
Note that the flat inclined surface 102B may be formed as an inclined surface having a substantially arc-shaped cross section that protrudes toward the wall surface 102A (for example, corresponds to the inclined surface 72B in FIG. 17). Accordingly, when a thin plastic plate or the like is inserted from the gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the front end of the plastic plate becomes the guide rib portion of the front cover member 7. When it hits 44, the pachinko machine 101 is more easily bent in the rear side direction (in the direction of the arrow 103), and the thin plastic plate that has entered the groove 102 is located at any position over the entire length of the groove 102. In a state where the rear end portion of the wall surface 102A is pressed against the inclined surface having a substantially arc-shaped cross section, a dead end is formed at the sharp bottom of the groove portion 102, so that it is extremely difficult to enter a game area such as a thin plastic plate. It can be difficult.
Here, the wall surface 102A functions as a first wall surface. The inclined surface having a substantially arc-shaped cross section protruding toward the wall surface 102A functions as a second wall surface.
[0078]
Further, the present invention is not limited to the first to ninth embodiments, and it goes without saying that various improvements and modifications can be made without departing from the spirit of the present invention.
For example, in the first to ninth embodiments, each of the reinforcing ribs 23, 32, and 42 and each of the grooves 24 to 102 are formed in a shape in which a portion facing the upper hinge 4 is partially cut off. Alternatively, it may be formed in a continuous shape according to the shape of the inner side wall portion of the front cover member 7. Accordingly, even when a thin plastic plate (for example, a plastic plate having a thickness of about 0.5 mm) or the like is inserted from a gap between the side wall portion of the front cover member 7 near the upper hinge 4 and the front frame 3, After the plates and the like abut against the reinforcing ribs 23, 32, and 42, they enter the respective grooves 24 to 102 and reach a dead end on the back side, and the side wall and the front frame of the front cover member 7 near the upper hinge 4 3, it is possible to make it more difficult to enter the game area from the gap.
