Description

【０００１】
【発明の属する技術分野】
この発明は、パチンコ機、アレンジボール等の遊技機に関する。
【０００２】
【従来の技術】
従来例を図１３により説明する。図１３はパチンコ機の遊技盤とガラス板との関係を示す断面図である。パチンコ機は、遊技盤面１０７ａを前面に有する遊技盤１０７を固定状に設けた遊技機本体（図示省略）と、該遊技機本体にヒンジ機構（図示省略）を介してその本体の前面側（図１３において左側）を開閉可能に設けた表側扉体１２０とを備えている。表側扉体１２０には、透視可能な内外（すなわち図１３において右左）２枚のガラス板１３２がガラス板装着枠１２６を介して支持されている。表側扉体１２０の閉鎖（図１３参照）によって、遊技盤１０７の前方の遊技者は、両ガラス板１３２を透して遊技盤面１０７ａを視認することができる。
【０００３】
【発明が解決しようとする課題】
ところで、各ガラス板１３２は、ガラス板装着枠１２６の内外の各装着溝１２６ａにそれぞれ周縁部を差し入れることによって、該ガラス板装着枠１２６に支持されている。また、各装着溝１２６ａの溝幅１２６ｗは、ガラス板１３２の差し入れ作業性等を考慮し、ガラス板１３２の板厚１３２ｔに所定のクリアランスＣを加えた寸法に設定される。
【０００４】
したがって、各ガラス板１３２が前記クリアランスＣの範囲内で前後方向すなわち板厚方向（図１３において左右方向）に「がたつき」を生じる、いわゆるがたつくことになる。したがって、ガラス板１３２とくに遊技盤面１０７ａに面する内側のガラス板（内ガラス板という）１３２のがたつきによって、表側扉体１２０の閉鎖時における遊技盤１０７の遊技盤面１０７ａと該内ガラス板１３２との間の距離ｄが変化することになる。
【０００５】
また、遊技機本体に表側扉体１２０を開閉可能に取り付けている表側扉体用ヒンジ機構（図１における符号、２２参照）におけるがたつきによって、ガラス板装着枠１２６ががたつく。このことによっても、遊技盤１０７の遊技盤面１０７ａと内ガラス板１３２との間の距離ｄ（図１３参照）が、パチンコ機の１台毎に異なったり、同一の台においても表側扉体１２０の上部と下部とで異なることがあった。また、表側扉体１２０の施錠装置（図１における符号、２４参照）におけるがたつきや、不心得者の表側扉体１２０を引っ張る行為の影響を受けることによっても、ガラス板装着枠１２６ががたつくため、遊技盤１０７の遊技盤面１０７ａと内ガラス板１３２との間の距離ｄ（図１３参照）を一定に保つことが困難であった。
【０００６】
なお、遊技盤１０７の遊技盤面１０７ａと内ガラス板１３２との間の距離ｄは、通常、経験や試験等で定められた寸法に設定される。例えば、遊技球いわゆるパチンコ球Ｂの球径が１１ｍｍであり、遊技盤面１０７ａに突出する釘（誘導釘とも呼ばれている）１１７の最大高さが１８ｍｍである場合には、前記距離ｄは基準値、例えば１９ｍｍに設定される。この場合、前記距離ｄが基準値の１９ｍｍより小さすぎても逆に大きすぎても、パチンコ球Ｂの流れが不安定となる。例えば、前記距離ｄが小さすぎる場合には、内ガラス板１３２にパチンコ球Ｂが当たる頻度が増加する。また、逆に大きすぎる場合には、パチンコ球Ｂが遊技盤面１０７ａ上で詰まるといったいわゆる「球噛み現象」が発生しやすくなる。このような球噛み現象が甚だしい場合には、遊技を中断せざるを得ない状態に陥るため、前記距離ｄを一定に保つことは重要である。
【０００７】
本発明が解決しようとする課題は、遊技盤の遊技盤面と透視板との間の距離を一定に保つことのできる遊技機を提供することにある。
【０００８】
【課題を解決するための手段】
外枠の前面側に横開き形態で開閉可能に装着されるベース枠と、
前記ベース枠に開設された開口部の後側に合わせて設けられて枠内部に段差面を形成した遊技盤装着枠と、
前記遊技盤装着枠の開口面域の後側から着脱可能にセットされて前記段差面に遊技盤面を当接させた位置に保持される遊技盤と、
前記遊技盤装着枠の後側に横開き形態で開閉可能に装着されて該遊技盤装着枠にセットされた前記遊技盤の裏面と間隔を置いた閉じ状態に締付具で保持される裏セット部材と、
前記ベース枠の前側に横開き形態で開閉可能に装着されて遊技盤の遊技盤面の遊技領域を透視し得る開口窓を形成した表側扉体と、
前記表側扉体の開口窓の後側に装着された透視板装着枠のレール状の装着溝に起立状態で支持されて前記遊技盤の遊技領域を透視可能に覆う内外２枚の透視板と、を備えた遊技機において、
前記裏セット部材に、前後方向への弾性変形可能で前記遊技盤装着枠内にセットされた前記遊技盤の後面の左側及び右側の上下部に弾性的に当接して該遊技盤を常には前記遊技盤装着枠の段差面に向けて押圧するための複数個の弾性片を配置し、
前記遊技盤の遊技領域外周の前面に遊技領域の前後方向の間隔を一定に保持するためスペーサ部材を装着し、
前記スペーサ部材の左側及び右側の上下部に、前記表側扉体における内側の透視板の後面各部に当接する凸部を配置して、スペーサ部材の後端から凸部の前端を含む厚みを、遊技盤面と内側の透視板の後面との間の所定の距離に見合う寸法に設定し、
前記ベース枠の前側に対して前記表側扉体が本来の閉鎖位置に保持された状態において、前記透視板装着枠の内側の透視板の後面が前記遊技盤装着枠内にセットされた前記遊技盤のスペーサ部材の凸部の前端と当接した状態で、前記遊技盤面と内側の透視板の後面との間を前記所定の距離に保持し得るように構成した遊技機を提供する。
【０００９】
本発明の遊技機によると、透視板装着枠を介して透視板を支持した表側扉体によって、ベース枠の前面側が開閉される。また、表側扉体の閉鎖によって、遊技盤の遊技盤面が透視板を透して視認可能となる。ところで、表側扉体の閉鎖時には、裏セット部材の弾性片の弾性変形を利用して、遊技盤が移動し、その遊技盤と透視板とがスペーサ部材と凸部を介して間接的に当接し合うことにより、遊技盤の遊技盤面と透視板との間の距離を一定に保つことができる。
【００１０】
また、本発明の遊技機によると、ベース枠に備えた遊技盤装着枠に遊技盤が後面側から嵌め込まれた後、裏セット部材が閉鎖される。これにより、遊技盤が遊技盤装着枠に嵌め込んだ状態にセットされるとともに、遊技盤が弾性片の弾性により付勢される。また、裏セット部材の開放時には、遊技盤装着枠に対する遊技盤の脱着が行えるとともに、遊技盤に対する弾性片の付勢が解除される。
【００１１】
【発明の実施の形態】
［実施の形態１］
この発明の実施の形態１を図面にしたがって説明する。実施の形態１は、遊技機の一つであるパチンコ機に本発明を適用したものを例示する。また、パチンコ機の基本的な構成を述べた後で要部について詳述する。
【００１２】
まず、パチンコ機の基本的な構成を述べる。パチンコ機の基本的な構成については、例えば同一出願人が先に提案した特開平１０−２７７２３２号公報に開示されたものとほとんど同様であるから簡単に述べるにとどめる。図１はパチンコ機を表側扉体の開放状態で示す斜視図である。説明の都合上、パチンコ機の遊技者側に向かう側を前方、反対側を後方と称する。なお、図面における方位は各図に矢印で示す通りに定める。
【００１３】
図１に示すように、パチンコ機１は、大別すると、遊技機本体２と表側扉体２０とを備えている。遊技機本体２から説明する。遊技機本体２は、外枠３とベース枠５とを備えている。外枠３は、ほぼ矩形枠状に形成されている。その外枠３の前面の下部には、ベース受板３Ａが設けられている。
【００１４】
また、前記ベース枠５は、ほぼ方形の額縁状に形成されている。ベース枠５は、前記外枠３に対してベース枠用ヒンジ機構６を介して回動可能すなわち外枠３の前面側に開閉可能に支持されている。前記ベース枠５には、ほぼ四角形板状で遊技盤面７ａを前面に有する遊技盤７が遊技盤装着枠（後述する）を介して支持されている。遊技盤面７ａには、ほぼ平帯状をなす案内レール８が装着されている。案内レール８により遊技領域および発射案内路が形成されている。
【００１５】
なお、図示はしないが、遊技盤面７ａの案内レール８内の遊技領域には、各種の入賞装置、役物装置、図柄表示装置、アタッカ装置、ゲート口、風車器、誘導釘等が配置されている。また、遊技盤７の後面には、前記各種の入賞装置、役物装置、図柄表示装置、アタッカ装置等を電気的に制御する制御ボックス装置（図示省略）が装着されている。
【００１６】
図２に示すように、前記ベース枠５の後面には、前記遊技盤７を取り囲む遊技盤装着枠９が設けられている。遊技盤装着枠９には、前記遊技盤７が着脱可能に嵌込まれている。また、ベース枠５には、前記遊技盤７の後面の制御ボックス装置（図示省略）を取り囲む裏セット部材４０が裏セット用ヒンジ機構（図示省略）を介して後面側に開閉可能に支持されている。裏セット部材４０の裏面には、その上部から下部に向けて、球タンク４５、球誘導樋４６、球払出装置４８等が配設されている。なお、裏セット部材４０の主体部分は、例えば、樹脂成形によって形成されている。
【００１７】
前記遊技盤装着枠９には、裏セット部材４０を閉じ状態に保持するための複数の締付具４４が配設されている。締付具４４は、裏セット部材４０を遊技盤装着枠９に閉じた状態に締付けて保持する。これとともに、遊技盤装着枠９に遊技盤７がセットされる。また、逆に、裏セット部材４０に対する締付具４４の締付けを解放することにより、裏セット部材４０を開くことができる。裏セット部材４０を開いた状態では、遊技盤装着枠９に対し遊技盤７を脱着させることができる。
【００１８】
図１に示すように、前記ベース枠５の下部には、前板１１がヒンジ機構（図示省略）を介して回動可能すなわちベース枠５の前面側に開閉可能に支持されている。前板１１の裏面には、ベース枠５に対し前板１１を閉じ状態に保持する施錠金具１２が配設されている。また、前板１１の前面には上皿１３が設けられている。また、ベース枠５の下端部には、球発射用ハンドル装置１４、下皿１５等が設けられている。
【００１９】
次に、表側扉体２０を説明する。図１に示すように、表側扉体２０は、前記ベース枠５に対して表側扉体用ヒンジ機構２２を介して回動可能すなわち前記遊技機本体２のベース枠５の前面側に開閉可能に支持されている。この表側扉体２０は、大別すると、例えば金属製の扉支持体２１と、例えば樹脂製の扉装飾体３５とを備えている。なお、前記表側扉体用ヒンジ機構２２は、扉支持体２１に配置されている。
【００２０】
前記扉支持体２１の中央部には、前記遊技盤７の遊技盤面７ａの遊技領域を露出可能なほぼ円形の開口窓２３が形成されている。また、扉支持体２１の自由端側の裏面には、表側扉体用施錠装置２４が装着されている。表側扉体用施錠装置２４には、例えば、上中下の計３つの扉施錠用フック２５が上下方向にスライド可能に組み付けられている。前記ベース枠５に対し表側扉体２０が閉じられたときには、表側扉体用施錠装置２４の扉施錠用フック２５がベース枠５に形成された係合穴５ａに係合することによって、ベース枠５に対し表側扉体２０が閉鎖状態に施錠される。なお、ベース枠５に設けられた鍵穴５ｂに対し鍵（図示省略）を挿入して、その鍵を回動操作することにより、係合穴５ａに対する前記扉施錠用フック２５の係合を解除いわゆる解錠することができる。
【００２１】
前記扉支持体２１の裏面には、ガラス板装着枠２６が配設されている。ガラス板装着枠２６は、開口窓２３の下方において左右方向に延びる金属製の下枠材２７と、その下枠材２７の左右両端部から上方に延びる左右の金属製の両側枠材２８と、その両側枠材２８の上端部の相互間に架設された上枠材２９とを備えている。なお、図３に表側扉体を省略して示すパチンコ機１の正面図、図４に図３のＩＶ−ＩＶ線断面図、図５に図３のＶ−Ｖ線断面図が示されている。
【００２２】
図４に示すように、前記ガラス板装着枠２６の下枠材２７には、内外（すなわち図４において左右）２条の装着溝２７ａが形成されている。図５に示すように、前記ガラス板装着枠２６の両側枠材２８には、それぞれ内外（すなわち図５において上下）２条の装着溝２８ａが形成されている。また、両側枠材２８（図５参照）の相互間の上端開口部が、図４に示すように、上枠材２９（後述する）によって開閉されるガラス板差し入れ口３９となっている。
【００２３】
図４および図５に示すように、前記ガラス板装着枠２６には、ほぼ四角形板状をなす前後２枚の透視可能なガラス板３２が支持されている。すなわち、図４に示される上枠材２９（後述する）を開いて、前記ガラス板差し入れ口３９を開放した状態において、該ガラス板差し入れ口３９から各ガラス板３２の左右の両側縁部が両側枠材２８の各装着溝２８ａ（図５参照）に差し入れられ、その各ガラス板３２の下縁部が下枠材２７の各装着溝２７ａ（図４参照）に差し入れられている。また、各ガラス板３２は、例えば、無色透明なガラス板３２であるが、樹脂製の透視可能な板材に代えることができる。なお、ガラス板３２は本明細書でいう「透視板」に相当し、また、ガラス板装着枠２６は本明細書でいう「透視板装着枠」に相当している。また、後側すなわち遊技盤側（図４において左側）に配置されるガラス板３２を「内ガラス板」と称し、前側すなわち反遊技盤側（図４において右側）に配置されるガラス板３２を「外ガラス板」と称する。
【００２４】
図１に示すように、前記ガラス板装着枠２６の両側枠材２８の上端部には、前記ガラス板差し入れ口３９を開閉する樹脂製の上枠材２９が設けられている。なお、上枠材２９は、ガラス板装着枠２６の両側枠材２８に対し左右対称状に設けられているから、左側部分について説明し、右側部分についての説明は省略する。図６はガラス板装着枠の上枠体を一部破断して示す左側面図である。
【００２５】
図６に示すように、前記側枠材２８の上端部の外側面に支持ピン３１が突出されている。一方、前記上枠材２９の左右両端部には、長細状のスライド孔３０ａを有するアーム片３０が設けられている。アーム片３０のスライド孔３０ａは、前記支持ピン３１に対しスライド可能にかつ回動可能に係合されている。また、上枠材２９には、前記両側枠材２８の各装着溝２８ａと連続状をなす各装着溝２９ａが形成されている（図４参照）。
【００２６】
前記上枠材２９は、図６に実線２９で示す閉止位置に配置されたときには、前記ガラス板差し入れ口３９を閉じるとともに、前記ガラス板装着枠２６の各装着溝２９ａに各ガラス板３２の上縁部を受け入れる（図４参照）。また、上枠材２９をスライドさせて図６に二点鎖線２９（１）で示すように引上げた後、支持ピン３１の回りに回動させて図６に二点鎖線２９（２）で示す開放位置に配置する。これにより、前記ガラス板差し入れ口３９を開放させることができる。この状態では、ガラス板差し入れ口３９を通じて、ガラス板装着枠２６に対して各ガラス板３２を出し入れすることができる。
【００２７】
上記のようにガラス板装着枠２６を介して２枚のガラス板３２を支持した表側扉体２０が、遊技機本体２（図１参照）に閉鎖されることによって、遊技盤７の遊技盤面７ａが２枚のガラス板３２を透して視認可能となる（図４及び図５参照）。このため、遊技盤７の前方の遊技者は、両ガラス板３２を透して遊技盤面７ａを視認することができる。
【００２８】
また、図４及び図５に示すように、前記表側扉体２０における扉装飾体３５は、前記扉支持体２１の前面側に取り付けられている。扉装飾体３５は、扉支持体２１の前記開口窓２３（図１参照）の周囲を取り囲むように配置されている。扉装飾体３５の表面側には、凹凸の装飾が施されている。
【００２９】
次に、上記したパチンコ機１の要部構成について説明する。図７はパチンコ機の遊技盤とガラス板とスペーサ部材との関係を示す側断面図、図８は表側扉体の閉鎖時の要部を示す断面図、図９は表側扉体の開放時の要部を示す断面図である。なお、図４および図５に示される前記ガラス板装着枠２６における各枠材２７，２８，２９の各装着溝２７ａ，２８ａ，２９ａの溝幅（前後方向の幅）を、装着溝幅２６Ｗ（図９参照）という。図９に示すように、前記ガラス板装着枠２６における各装着溝の装着溝幅２６Ｗは、ガラス板３２の差し入れ作業性等を考慮し、ガラス板３２の板厚３２ｔに所定のクリアランスＣを加えた寸法に設定されている。
【００３０】
図９に示すように、前記遊技盤７は、前記遊技盤装着枠９にその後面側から嵌め込まれており、その嵌め込み時には遊技盤装着枠９の段差面９ａに遊技盤面７ａが面接触状に当接することによって、その前方への移動が規制される。また、遊技盤７は、前にも述べたように、遊技盤装着枠９に対し裏セット部材４０が閉じられることによって、該遊技盤装着枠９に嵌め込んだ状態にセットされる。
【００３１】
図１０は裏セット部材の開放時の要部を示す断面図、図１１は裏セット部材の背面図である。図１１に示すように、裏セット部材４０には、前記遊技盤７の左右の両側端部にそれぞれ対応する、例えば上中下の計３つの弾性片４２が一体で形成されている。なお、裏セット部材４０は本明細書でいう「裏側扉体」に相当している。
【００３２】
前記各弾性片４２は、図１２に斜視図で示すように、裏セット部材４０に形成されたほぼ四角形状の開口穴４１の上縁部から下方へ突出する基部４２ａと、その基部４２ａの下端部から前下方へ傾斜状に突出する傾斜部４２ｂと、その傾斜部４２ｂの下端部から下方へ突出する押え部４２ｃとを有している。弾性片４２は、図１２に二点鎖線４２で示すように、傾倒方向に弾性変形可能に形成されている。また、裏セット部材４０の開口穴４１は、樹脂成形用金型における弾性片４２の形成のための型部分によって形成される抜き穴である。
【００３３】
図１０に示すように、前記遊技盤装着枠９に前記遊技盤７を嵌め込んだ状態で、該遊技盤装着枠９に対し前記裏セット部材４０が閉じられる。すると、図９に示すように、該裏セット部材４０の弾性片４２の押え部４２ｃが前記遊技盤７の後面すなわち裏面に対し弾性的に当接する。これにより、遊技盤７は、裏セット部材４０の弾性片４２の弾性により、遊技盤面７ａが遊技盤装着枠９の段差面９ａに面接触状に当接される状態に付勢され、かつ、その弾性片４２の弾性変形を利用して板厚方向すなわち後方へ所定の移動量をもって移動可能に支持される。このようにして、裏セット部材４０の弾性片４２は、遊技盤装着枠９に対し遊技盤７をフローティング支持している。なお、弾性片４２は本明細書でいう「弾性手段」に相当している。
【００３４】
また、図３および図７に示すように、前記遊技盤７の遊技盤面７ａにおいて、前記表側扉体２０（図７参照）によって隠蔽される部分すなわち前記遊技領域外の部分には、ほぼ板状のスペーサ部材５０が設けられている。本実施の形態の場合、図３に示すように、スペーサ部材５０は、左側に上下２個、右側に上下に連続する１個が配置されている。
【００３５】
図３に示すように、前記各スペーサ部材５０の前面５０ａには、１個または２個のほぼ半球状の凸部５１（図９参照）が突出されている。この凸部５１は、前記内ガラス板３２の左上部、左下部、右上部、右下部に対応する計４個が設定されている。スペーサ部材５０の凸部５１を含む肉厚５０ｔ（図９参照）は、図８に示すように、表側扉体２０の閉鎖時において、前記遊技盤７の遊技盤面７ａと内ガラス板３２との間の所定の距離ｄに見合う寸法に設定されている。
【００３６】
上記した遊技盤７において、表側扉体２０が図９に示す開放状態から図７および図８に示すように閉鎖されたときには、各スペーサ部材５０の凸部５１（図８参照）に内ガラス板３２（詳しくは、図８において右側のガラス板３２の後側面）が当接する。さらに、内ガラス板３２が、前記ガラス板装着枠２６の後側（図８において右側）の装着溝（例えば、上枠材２９の装着溝２９ａ）における前側の溝壁面（図８に符号、２９ａ１を付す）に当接される状態となる。その後、裏セット部材４０の弾性片４２の弾性変形を利用して遊技盤７が後方（図８において右方）へ押しやられた状態となる。このとき、遊技盤７の遊技盤面７ａは、遊技盤装着枠９の段差面９ａから離れる。
【００３７】
これにより、図８に示すように、裏セット部材４０の弾性片４２の弾性変形を利用して、遊技盤７と内ガラス板３２とがスペーサ部材５０を介して間接的に当接し合う。これにより、遊技盤７の遊技盤面７ａと内ガラス板３２との間の距離ｄを盤面全体にわたって一定に保つことができる。なお、その距離ｄは、遊技盤７の移動量の範囲内においてほぼ一定に保つことができる。したがって、遊技盤７の遊技盤面７ａと内ガラス板３２との間でのパチンコ球Ｂの流れを安定化することができ、ひいては、ガラス板３２にパチンコ球Ｂが当たる頻度の増加や球噛み現象の発生といった不具合を防止することができる。
【００３８】
また、遊技機本体２のベース枠５の後面側を開閉する裏セット部材４０の閉鎖時（図９参照）には、遊技盤７が弾性片４２の弾性により付勢される。また、裏セット部材４０の開放時（図２および図１０参照）には、遊技盤７に対する弾性片４２（図１１参照）の付勢が解除される。したがって、遊技盤７に対する弾性片４２の付勢およびその付勢の解除を、裏セット部材４０の閉鎖動作および開放動作を利用して容易に行うことができる。
【００３９】
また、遊技機本体２に備えた遊技盤装着枠９に遊技盤７が後面側から嵌め込まれた後（図２および図１０参照）、裏セット部材４０が閉鎖される（図９参照）。これにより、遊技盤７が遊技盤装着枠９に嵌め込んだ状態にセットされるとともに、遊技盤７が弾性片４２の弾性により付勢される。また、裏セット部材４０の開放時（図２および図１０参照）には、遊技盤装着枠９に対する遊技盤７の脱着が行えるとともに、遊技盤７に対する弾性片４２の付勢が解除される。
【００４０】
また、裏セット部材４０に弾性片４２が一体で形成されているため（図１２参照）、弾性片４２にかかる部品点数および組付工数を削減することができる。
【００４１】
本発明は前記実施の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における変更が可能である。例えば、本発明は、パチンコ機１以外の遊技機に適用することも可能である。また、透視板支持枠に支持される透視板の枚数は、１枚あるいは３枚以上であってもよい。また、スペーサ部材５０（図９参照）は、遊技盤７に代えて、内ガラス板３２に設けることもできる。また、スペーサ部材５０は、遊技盤７および内ガラス板３２の双方に設けることもできる。また、裏セット部材４０とは別個に形成された弾性片４２を有する樹脂製、金属製あるいはゴム製の弾性部材を、裏セット部材４０に組付けることによって弾性手段を構成することもできる。また、弾性片４２は、裏セット部材４０に代え、遊技盤７あるいは遊技盤装着枠９に設けることも可能である。
【００４２】
【発明の効果】
以上述べたように、この発明によれば、表側扉体の閉鎖時には、裏セット部材の弾性片の弾性変形を利用して遊技盤が移動し、その遊技盤と透視板とがスペーサ部材と凸部を介して間接的に当接し合うことにより、遊技盤の遊技盤面と透視板との間の距離を一定に保つことができる。

[Problems to be solved by the invention]
By the way, each glass plate 132 is supported by the glass plate mounting frame 126 by inserting a peripheral edge into each mounting groove 126 a inside and outside the glass plate mounting frame 126. Further, the groove width 126w of each mounting groove 126a is set to a dimension obtained by adding a predetermined clearance C to the plate thickness 132t of the glass plate 132 in consideration of the insertion workability of the glass plate 132 and the like.
[0004]
Accordingly, each glass plate 132 is so-called rattling that causes “rattle” in the front-rear direction, that is, the thickness direction (left-right direction in FIG. 13) within the range of the clearance C. Therefore, when the front door 120 is closed, the gaming board surface 107a of the gaming board 107 and the inner glass board 132 when the front door 120 is closed due to the rattling of the inner glass board (referred to as the inner glass board) 132 facing the glass board 132, particularly the gaming board surface 107a. The distance d between and will change.
[0005]
Further, the glass plate mounting frame 126 rattles due to rattling in the front door hinge mechanism (see reference numeral 22 in FIG. 1) that attaches the front door 120 to the gaming machine main body so as to be opened and closed. Also by this, the distance d (see FIG. 13) between the game board surface 107a of the game board 107 and the inner glass plate 132 is different for each pachinko machine, or even on the same board, There was a difference between the upper part and the lower part. Further, the glass plate mounting frame 126 is also rattled by the backlash of the locking device (see reference numeral 24 in FIG. 1) of the front door 120 and the influence of an unskilled person pulling the front door 120. Therefore, it is difficult to keep the distance d (see FIG. 13) between the game board surface 107a of the game board 107 and the inner glass plate 132 constant.
[0006]
The distance d between the game board surface 107a of the game board 107 and the inner glass plate 132 is usually set to a dimension determined by experience, tests, or the like. For example, when the ball diameter of the game ball so-called pachinko ball B is 11 mm and the maximum height of a nail 117 (also referred to as a guide nail) 117 protruding from the game board surface 107a is 18 mm, the distance d is the reference The value is set to 19 mm, for example. In this case, the flow of the pachinko sphere B becomes unstable if the distance d is too small or less than the reference value 19 mm. For example, when the distance d is too small, the frequency with which the pachinko sphere B hits the inner glass plate 132 increases. On the other hand, if it is too large, a so-called “ball biting phenomenon” in which the pachinko ball B is clogged on the game board surface 107a is likely to occur. When such a ball biting phenomenon is severe, the game is forced to be interrupted, so it is important to keep the distance d constant.
[0007]
The problem to be solved by the present invention is to provide a gaming machine capable of keeping the distance between the gaming board surface of the gaming board and the see-through board constant.

[0029]
Next, the configuration of the main part of the pachinko machine 1 described above will be described. FIG. 7 is a side sectional view showing the relationship between the game board of the pachinko machine, the glass plate, and the spacer member, FIG. 8 is a sectional view showing the main part when the front door is closed, and FIG. 9 is when the front door is opened. It is sectional drawing which shows the principal part. 4 and FIG. 5, the groove widths (widths in the front-rear direction) of the mounting grooves 27a, 28a, 29a of the frame members 27, 28, 29 in the glass plate mounting frame 26 shown in FIG. Refer to FIG. As shown in FIG. 9, the mounting groove width 26W of each mounting groove in the glass plate mounting frame 26 is obtained by adding a predetermined clearance C to the plate thickness 32t of the glass plate 32 in consideration of the insertion workability of the glass plate 32 and the like. The dimensions are set.
[0030]
As shown in FIG. 9, the gaming board 7 is fitted into the gaming board mounting frame 9 from the rear side, and the gaming board surface 7a is in surface contact with the stepped surface 9a of the gaming board mounting frame 9 when fitted. By abutting, the forward movement is restricted. Further, as described above, the game board 7 is set in a state of being fitted into the game board mounting frame 9 by closing the back set member 40 with respect to the game board mounting frame 9.
[0031]
FIG. 10 is a cross-sectional view showing the main part when the back set member is opened, and FIG. 11 is a rear view of the back set member. As shown in FIG. 11, the back set member 40 is integrally formed with, for example, a total of three upper and lower elastic pieces 42 corresponding to the left and right side ends of the game board 7. The back set member 40 corresponds to a “back side door body” in this specification.
[0032]
As shown in the perspective view of FIG. 12, each elastic piece 42 has a base portion 42a protruding downward from the upper edge portion of the substantially square opening hole 41 formed in the back set member 40, and a lower end of the base portion 42a. It has an inclined portion 42b that protrudes in a downwardly inclined manner from the front portion, and a presser portion 42c that protrudes downward from the lower end portion of the inclined portion 42b. The elastic piece 42 is formed so as to be elastically deformable in the tilt direction, as indicated by a two-dot chain line 42 in FIG. Moreover, the opening hole 41 of the back set member 40 is a punched hole formed by a mold portion for forming the elastic piece 42 in the resin molding die.
[0033]
As shown in FIG. 10, the back set member 40 is closed with respect to the game board mounting frame 9 in a state where the game board 7 is fitted into the game board mounting frame 9. Then, as shown in FIG. 9, the pressing portion 42 c of the elastic piece 42 of the back set member 40 elastically abuts against the rear surface, that is, the back surface of the game board 7. Thereby, the game board 7 is urged by the elasticity of the elastic piece 42 of the back set member 40 so that the game board surface 7a comes into contact with the stepped surface 9a of the game board mounting frame 9 in a surface contact state, and Using the elastic deformation of the elastic piece 42, the elastic piece 42 is supported so as to be movable with a predetermined amount of movement in the thickness direction, that is, rearward. Thus, the elastic piece 42 of the back set member 40 supports the game board 7 in a floating manner with respect to the game board mounting frame 9. The elastic piece 42 corresponds to “elastic means” in this specification.
[0034]
Further, as shown in FIG. 3 and FIG. 7, a portion of the gaming board surface 7a of the gaming board 7 that is concealed by the front door body 20 (see FIG. 7), that is, a portion outside the gaming area is substantially plate-like. The spacer member 50 is provided. In the case of the present embodiment, as shown in FIG. 3, two spacer members 50 are arranged on the left and right and one on the right and the upper and lower are continuous.
[0035]
As shown in FIG. 3, one or two substantially hemispherical convex portions 51 (see FIG. 9) protrude from the front surface 50 a of each spacer member 50. A total of four convex portions 51 corresponding to the upper left portion, the lower left portion, the upper right portion, and the lower right portion of the inner glass plate 32 are set. As shown in FIG. 8, the thickness 50t (see FIG. 9) including the convex portion 51 of the spacer member 50 is such that the game board surface 7a of the game board 7 and the inner glass plate 32 are closed when the front door 20 is closed. The dimension is set to meet a predetermined distance d.
[0036]
In the gaming board 7 described above, when the front door 20 is closed from the open state shown in FIG. 9 as shown in FIGS. 7 and 8, the inner glass plate is formed on the convex portion 51 (see FIG. 8) of each spacer member 50. 32 (specifically, the rear side surface of the right glass plate 32 in FIG. 8) abuts. Further, the inner glass plate 32 has a groove wall on the front side (reference numeral 29a1 in FIG. 8) in a mounting groove (for example, a mounting groove 29a of the upper frame material 29) on the rear side (right side in FIG. 8) of the glass plate mounting frame 26. To be abutted). Thereafter, the game board 7 is pushed rearward (rightward in FIG. 8) by utilizing the elastic deformation of the elastic piece 42 of the back set member 40. At this time, the game board surface 7 a of the game board 7 is separated from the step surface 9 a of the game board mounting frame 9.
[0037]
Thus, as shown in FIG. 8, the game board 7 and the inner glass plate 32 abut against each other via the spacer member 50 by utilizing the elastic deformation of the elastic piece 42 of the back set member 40. Thereby, the distance d between the game board surface 7a of the game board 7 and the inner glass plate 32 can be kept constant over the whole board surface. The distance d can be kept substantially constant within the range of the movement amount of the game board 7. Therefore, the flow of the pachinko ball B between the game board surface 7a of the game board 7 and the inner glass plate 32 can be stabilized. As a result, an increase in the frequency with which the pachinko ball B hits the glass plate 32 and a ball biting phenomenon. It is possible to prevent problems such as the occurrence of
[0038]
Further, when the back set member 40 that opens and closes the rear surface side of the base frame 5 of the gaming machine main body 2 is closed (see FIG. 9), the gaming board 7 is biased by the elasticity of the elastic piece 42. Further, when the back set member 40 is opened (see FIGS. 2 and 10), the bias of the elastic piece 42 (see FIG. 11) with respect to the game board 7 is released. Therefore, the biasing of the elastic piece 42 with respect to the game board 7 and the release of the biasing can be easily performed using the closing operation and the opening operation of the back set member 40.
[0039]
Further, after the gaming board 7 is fitted into the gaming board mounting frame 9 provided in the gaming machine main body 2 from the rear side (see FIGS. 2 and 10), the back set member 40 is closed (see FIG. 9). Thereby, the game board 7 is set in a state of being fitted in the game board mounting frame 9 and the game board 7 is biased by the elasticity of the elastic piece 42. In addition, when the back set member 40 is opened (see FIGS. 2 and 10), the game board 7 can be attached to and detached from the game board mounting frame 9, and the bias of the elastic piece 42 to the game board 7 is released.
[0040]
Further, since the elastic piece 42 is integrally formed on the back set member 40 (see FIG. 12), the number of parts and the number of assembling steps applied to the elastic piece 42 can be reduced.
[0041]
The present invention is not limited to the embodiment described above, and can be modified without departing from the gist of the present invention. For example, the present invention can be applied to gaming machines other than the pachinko machine 1. Further, the number of fluoroscopic plates supported by the fluoroscopic plate support frame may be one or three or more. Further, the spacer member 50 (see FIG. 9) can be provided on the inner glass plate 32 instead of the game board 7. The spacer member 50 can also be provided on both the game board 7 and the inner glass plate 32. Further, the elastic means can be configured by assembling the back set member 40 with a resin, metal or rubber elastic member having an elastic piece 42 formed separately from the back set member 40. Further, the elastic piece 42 can be provided on the game board 7 or the game board mounting frame 9 instead of the back set member 40.
[0042]
【The invention's effect】
As described above, according to the present invention, when the front door is closed, the game board moves using the elastic deformation of the elastic piece of the back set member, and the game board and the see-through board are protruded from the spacer member. The distance between the game board surface of the game board and the see-through board can be kept constant by making contact indirectly through the section.
