Description

【０００１】
【発明の属する技術分野】
本発明は、矩形状の外枠と、この外枠に対して縦方向のヒンジにより開閉自在に取り付けられる前枠とを備え、外枠には、前枠を閉じた状態でこの前枠の下面に対向する対向面を形成したパチンコ機、アレンジボール機、スロットマシン等の各種遊技機に関するものである。
【０００２】
【従来の技術】
パチンコ機、アレンジボール機、スロットマシン等の遊技機では、矩形状の外枠と、この外枠に対して縦方向のヒンジにより開閉自在に取り付けられる前枠とを備え、外枠（例えば外枠の前側下部に固定される左右方向の下枠材上）に、前枠を閉じた状態でこの前枠の下面に対向する対向面を形成したものが一般的である。
【０００３】
この種の遊技機では、前枠の裏面側に、各種入賞手段や表示手段等が装着された遊技盤、払い出し装置、発射手段等が取り付けられ、更にその前面側には、遊技盤の前側を覆うガラス扉、遊技球を貯留する上皿が装着された前面板、余剰球を貯留する下皿等が取り付けられている。
【０００４】
このように、前枠は多数の部品が取り付けられているために重量が大きく、この前枠を開閉する際には、前枠を支持しているヒンジに過大な荷重が作用することとなる。その結果、前枠を開いたときにはその前枠の開閉端側（ヒンジとは反対側の端部）が外枠側の対向面（例えば下枠材の上面）よりも垂れ下がった状態となるため、前枠を閉じる際には、単に前枠をヒンジ廻りに回転させただけでは前枠の下部後縁側が外枠側の対向面の前部と干渉してスムーズに閉じることができず、例えば前枠を持ち上げながら回転させるなどの煩わしい作業が必要であった。
【０００５】
そこで、従来より、前枠側に案内輪を設け、前枠を閉じる際にその案内輪が外枠側の対向面に乗り上げるように構成して、前枠下端部と外枠とが擦れることなくスムーズに前枠を開閉できるようにしたものが知られている（例えば、特許文献１参照）。

【０００６】
【発明が解決しようとする課題】
このような案内輪を設けた従来の遊技機では、前枠を持ち上げなくても開閉動作をスムーズに行うことができるものの、案内輪が前枠の後側に大きく突出してしまうため、例えば前枠を開放した状態での作業の邪魔になって作業効率が低下するなどの欠点があった。
【０００７】
また、前枠側の構成がより一層複雑となり、組み立て工程が複雑化してしまうといった問題点もあった。
【０００８】
本発明は上記事情に鑑みてなされたものであり、前枠の後ろ側に大きな突起物を設けることなく、前枠の開閉をスムーズに行うことが可能な遊技機を提供することを目的とする。
【０００９】
【課題を解決するための手段】
上記目的を達成するために、本発明は、矩形状の外枠１と、該外枠１に対して縦方向のヒンジ４により開閉自在に取り付けられる前枠３とを備え、該外枠１には、前記前枠３を閉じた状態で該前枠３の下面３ａに対向する対向面２ａを形成した遊技機において、前記外枠１側に、前記前枠３を閉じる際にその前枠３に押されて左右方向の回転軸４５廻りに回動しつつ前記前枠３の下面３ａを前記対向面２ａの上側に押し上げる回転案内部材４６を備え、該回転案内部材４６は、前記前枠３を閉じる際にその前枠３の下面側後端部が当接する当接受け部５７が前記対向面２ａの前端側よりも前側で且つ前記回転軸４５よりも上側の位置に保持される第１状態と、その略全体が前記対向面２ａの下側に収容される第２状態との間で上向きに揺動自在に構成され、その揺動時に、前記当接受け部５７が前記対向面２ａの前端の外側を通過するように構成されているものである。
【００１０】
【発明の実施の形態】
以下、本発明の各実施形態を図面に基づいて詳述する。図１〜図７は本発明をパチンコ機に採用した第１の実施形態を例示している。図１及び図２において、１は外枠で、左右一対の縦枠材１ａ，１ｂと上下一対の横枠材１ｃ，１ｄとが矩形状に組み合わされ、更に下側の横枠材１ｄに沿って左右の縦枠材１ａ，１ｂの前側を連結する左右方向の下枠材２が固定されて形成されている。
【００１１】
また、外枠１の前側には、前枠３が、左右一端側、例えば向かって左側の端部に設けられた上下一対の縦方向のヒンジ４によって開閉自在に取り付けられている。前枠３は、外枠１側に閉じたとき、その下面３ａが下枠材２の上面（対向面）２ａに対向するようになっている。
【００１２】
５はガラス扉、６は前面板で、これらは前枠３の窓孔７に対応して上下に配置され、前枠３に開閉自在に枢支されている。８は発射用の遊技球を貯留する上皿で、前面板６の前側に装着され、上皿カバー９により覆われている。また、１０は余剰球等を貯留する下皿で、前面板６の下側で前枠３の前側に装着され、下皿カバー１１により覆われている。
【００１３】
１２は遊技盤で、前枠３の窓孔７に対応するように、前枠３の裏側に設けられた門型状の遊技盤装着枠１３に裏側から着脱自在に装着され、窓孔７の下部側で前枠３の裏側に装着された支持板（図示省略）により下側から支持されている。
【００１４】
１５は発射手段で、前枠３の下部の左右方向一端側、例えば右端側に配置されており、前面板６の裏側に装着された球送り手段により発射レール１６上に１個ずつ供給される遊技球を発射方向に打撃する打撃槌１７と、この打撃槌１７を発射方向に付勢する付勢バネ１８と、カムを介して打撃槌１７を付勢バネ１８のバネ圧に抗して反発射方向に間欠的に駆動する発射モータ１９と、付勢バネ１８のバネ圧を任意に調整する操作ハンドル２０とを備えている。
【００１５】
打撃槌１７、付勢バネ１８、発射モータ１９等は取り付け板１５ａを介して前枠３の裏側に装着され、操作ハンドル２０は前枠３の前側に回動操作可能に突設されている。なお、操作ハンドル２０には、遊技者の把持を検出する接触検出スイッチ（図示省略）が設けられている。
【００１６】
遊技盤１２の前側には、図１に示すように、発射手段１５から発射された遊技球を案内するガイドレール２１が環状に装着されると共に、そのガイドレール２１の内側の遊技領域２２に、可変表示手段２３、普通図柄始動手段２４、特別図柄始動手段２５、大入賞手段２６、普通入賞手段２７等の各種遊技部品が配置されている。
【００１７】
前枠３の裏側には、図２に示すように、遊技盤１２を裏側から押さえて固定する裏機構板２８が開閉自在に装着されている。この裏機構板２８の略中央部分には開口部２８ａが形成され、その上側には遊技球タンク２９とタンクレール３０とが、左右方向の片側にはタンクレール３０の下流側に接続された払い出し装置３１が、下側には通路ユニット３２がそれぞれ設けられている。遊技球タンク２９からタンクレール３０を経由して払い出し装置３１から払い出された遊技球は、通路ユニット３２を経由して上皿８に排出される。
【００１８】
裏機構板２８の開口部２８ａには、遊技盤１２の裏側を覆う裏カバー３３が嵌合されている。この裏カバー３３には、主制御基板、ランプ制御基板、音声制御基板等を夫々収納した基板ケース３４，３５，３６等が着脱可能に装着されている。更に、裏カバー３３の下側の裏機構板２８上には、電源基板、払い出し制御基板等を収納した基板ケース３７等が着脱可能に装着されている。
【００１９】
下枠材２の上面２ａ側には、ヒンジ４とは反対側の端部近傍に案内ユニット４１が設けられている。案内ユニット４１は、図４等に示すように、左右一対の相対向する例えば矩形板状の側板部４２とそれら側板部４２の下端部を左右に接続する連結板部４３とを一体に備えた本体枠４４と、この本体枠４４の左右の側板部４２間に架け渡された左右方向の回転軸４５と、この回転軸４５により回動自在に支持された回転案内部材４６と、この回転案内部材４６を所定方向に付勢するコイルバネ等のバネ部材（付勢手段）４７とを備え、下枠材２の上面２ａ側に設けられた取り付け溝４８内に着脱自在に装着されている。
【００２０】
本体枠４４は、例えば金属製で、側板部４２の前後方向幅が下枠材２の板厚と略同一に形成されている。また取り付け溝４８は、下枠材２の裏面側から前面側にかけて前後方向に形成されており、その下枠材２の上面２ａからの深さは本体枠４４（側板部４２）の上下方向幅と、左右方向幅は本体枠４４（連結板部４３）の左右方向幅と、夫々略同一に形成されている。即ち、本体枠４４は、取り付け溝４８に嵌合したとき、側板部４２が取り付け溝４８の左右の側面に、連結板部４３が取り付け溝４８の底面に、夫々一致するようになっている。
【００２１】
本体枠４４の前側下部には、例えば金属製の回転軸４５が、その両端側を側板部４２に固定された状態で取り付けられている。
【００２２】
また、例えば本体枠４４の後部側には、左右の側板部４２の後縁部から下枠材２の裏面側に沿って固定板部４９が一体に形成されており、本体枠４４は、この固定板部４９を取り付けネジ５０でネジ止めすることにより下枠材２に対して着脱自在に固定されている。
【００２３】
なお、固定板部４９は、例えば本体枠４４の上部側に、下枠材２の上面２ａ側に沿って設けてもよい。但しこの場合には、固定板部４９の上面側が下枠材２の上面２ａよりも上側に突出しないように、下枠材２の上面２ａ側に固定板部４９を埋めこむための取り付け凹部を必ず形成する必要がある。また、固定板部４９は、例えば本体枠４４の前部側に、下枠材２の前面側に沿って設けてもよい。
【００２４】
回転案内部材４６は、前枠３を閉じる際にその前枠３の下端側に押されて回転軸４５廻りに回動し、前枠３の開閉端側を上向きに押し上げて前枠３の下面側後端部と下枠材２の上面側前端部との擦れを防止するためのもので、図５等に示すように、略直線状の３つの辺部５１〜５３を有し且つそれら３つの辺部５１〜５３で挟まれた３つの角部がＲ状（以下、Ｒ部５４〜５６という）に形成された側面視略三角形に形成されている。回転案内部材４６は、例えば金属製で、前枠３の重量に耐えられる程度の十分な強度を得られる板厚（左右方向寸法）に形成する必要がある。
【００２５】
また、回転案内部材４６は、図５に示すように、Ｒ部５４の近傍において回転軸４５により回動自在に保持されており、例えばそのＲ部５４を挟む一方の辺部５１側が本体枠４４の連結板部４３の前部上面側に当接する第１状態（図５に実線で示す）と、他方の辺部５２側が連結板部４３の後部上縁側に当接する第２状態との間で上向きに揺動可能となっている。
【００２６】
回転案内部材４６が第１状態にあるときには、少なくともＲ部５４に対向する辺部５３の略全体が下枠材２の前面側（上面２ａの前端側）よりも前側に突出した状態となり、前枠３を閉じる際にはその前枠３の下面側後端部がこの辺部５３上の１点（以下、当接受け部５７という）に当接するようになっている。
【００２７】
この辺部５３は、その略全体、少なくとも当接受け部５７となり得る範囲については、第１状態において下枠材２の前面側（上面２ａの前端側）よりも前側で且つ回転軸４５よりも上側の位置に保持されると共に、回転軸４５からこの当接受け部５７までの距離が、回転軸４５から下枠材２の上面側前端部までの距離よりも長くなるように形成されている。即ち、回転案内部材４６が第１状態と第２状態との間で揺動移動する際には、当接受け部５７は必ず下枠材２の上面側前端部の外側を移動する。
【００２８】
また、回転案内部材４６が第１状態にあるとき、辺部５３は例えば鉛直よりも若干前下がりの状態となり、またＲ部５５は下枠材２の上面側よりも若干上側に突出した状態となる。更に、回転案内部材４６が第２状態にあるときには、回転案内部材４６はその略全体が下枠材２２内に収容されて少なくとも下枠材２の上面２ａよりも上側に突出しないようになっている。
【００２９】
バネ部材４７は例えば回転軸４５に取り付けられており、その一端側４７ａが本体枠４４側に、他端側４７ｂが回転案内部材４６側に夫々係合され、回転案内部材４６を第２状態から第１状態に向けて付勢している。前枠３が閉じた状態では、回転案内部材４６は、バネ部材４７の付勢により、第２状態と第１状態との中間の状態、即ちその縁部上の１カ所（例えばＲ部５６又はその近傍）が前枠３の下面３ａに当接した中間状態（図５に二点鎖線で示す）で保持される。
【００３０】
前枠３の下面３ａ側には、図３等に示すように、下枠材２側の回転案内部材４６に対応して補強板６１が設けられている。補強板６１は、前枠３の下面側前端部から後端部を経て裏面側に至る部分を覆う断面Ｌ字型に形成されており、取り付けネジ６２等により前枠３に対して着脱自在に装着されている。
【００３１】
また、前枠３の下面３ａ側で且つ回転案内部材４６に対応する部分（即ち補強板６１の装着部分）よりもヒンジ４側には、その後部側を後上がりの傾斜状に切り欠いた案内傾斜面６３が形成されている。傾斜案内面６３は、前枠３を開いてその開閉端側の下面３ａが下枠材２の上面２ａよりも垂れ下がった状態となったとき、その後縁側６３ａが略水平となるように、後縁側６３ａがヒンジ４の近傍から補強板６１側に向けて前枠３の下面側に対して徐々に高くなるように形成されている。また、傾斜案内面６３は、その前後方向の傾斜角が左右方向全体にわたって略一定となっており、その前縁側６３ｂの位置がヒンジ４側から補強板６１側に向けて徐々に前側に移動する細長三角形状に形成されている。
【００３２】
続いて、前枠３の開閉時の動作状態について図５及び図６を参照しつつ説明する。図５に実線で示すように、前枠３を前側に開放した状態では、ヒンジ４のガタと前枠３の自重により、前枠３の開閉端側の下面３ａは閉鎖時の位置（下枠材２の上面２ａの位置）よりも垂れ下がった状態となる。
【００３３】
また、下枠材２側の案内ユニット４１は、回転案内部材４６がバネ部材４７の付勢により第１状態に保持されて辺部５３側が下枠材２の前側に突出した状態となっている。
【００３４】
この状態から前枠３を徐々に閉じてゆくと、前枠３の下面３ａ側がヒンジ４側から徐々に下枠材２の上面２ａ側に重なってゆく。このとき、前枠３の下面３ａ側には傾斜案内面６３が形成されているため、前枠３の下面３ａ側は下枠材２の上面２ａ側に殆ど擦れることはなく、また擦れたとしても傾斜案内面６３に案内されてスムーズに乗り上げてゆく。
【００３５】
そして、前枠３を所定位置まで閉じたとき、前枠３の下面側後端部が回転案内部材４６の辺部５３上の所定位置（当接受け部５７）に当接する（図６（ａ））。このとき、回転案内部材４６はその当接受け部５７に後ろ向きの力を受ける。当接受け部５７は回転軸４５よりも高い位置にあるため、その後ろ向きの力によって回転案内部材４６には回転軸４５廻りのモーメントが発生し、回転案内部材４６は前枠３の後方への移動に伴って後ろ向きに回転を始める。
【００３６】
回転案内部材４６が後ろ向きに回転を始めると、当接受け部５７の位置が徐々に上昇し、それによって前枠３はその当接受け部５７から上向きの力を受ける。これにより、前枠３はその下面側後端部を当接受け部５７に支持された状態で上斜め後方に持ち上げられる（図６（ｂ））。このとき、当接受け部５７は、下枠材２の上面側前端部の外側を移動するため、前枠３はその下面側後端部が下枠材２の上面側前端部に当接することなく下枠材２の上方に移動する。
【００３７】
その後、回転案内部材４６が更に回転し、当接受け部５７がその移動経路の最上位位置を過ぎると、例えば前枠３が回転案内部材４６上を相対的に転がって、前枠３と回転案内部材４６との当接位置が徐々に移動する（図６（ｃ））。即ち、回転案内部材４６側の支持位置が当接受け部５７からそれよりも前側に徐々に移動し、前枠３側の被支持位置がその下面３ａを徐々に前向きに移動する。
【００３８】
そして、やがて前枠３の下面３ａが下枠材２の上面２ａに当接すると、その後は前枠３は下枠材２の上面２ａ上を摺動しつつ全閉位置まで移動する（図６（ｄ））。その際、回転案内部材４６は、バネ部材４７の付勢により、その縁部上の１カ所（例えばＲ部５６又はその近傍）を前枠３の下面３ａに当接させた中間状態で保持される。
【００３９】
このように、本実施形態では、前枠３を閉じる際に、下枠材２側の回転案内部材４６が前枠３の下面側後端部に押されて後ろ向きに回転する際にその前枠３を上向きに押し上げつつ下枠材２の上面２ａの上側に案内するように作用するため、前枠３を持ち上げつつ回転させる等の煩わしい手順を踏むことなく前枠３の開閉をスムーズに行うことが可能となる。また、前枠３側にはその後方に突起するものがないため、前枠３を開放した状態での作業が阻害されることもない。
【００４０】
次に、前枠３を開放する場合には、前枠３及び回転案内部材４６は例えば図７のように動作する。即ち、前枠３を全閉状態から開方向に引き出すと、回転案内部材４６は、前枠３の下面３ａとの間の摩擦がある程度大きい場合には、前枠３の前側への移動と共に中間状態から前向きに回転を始める。これにより、前枠３側は回転案内部材４６側のＲ部５６から上向きの力を受けて上斜め前方に持ち上げられる（図７（ａ）→（ｂ））。
【００４１】
その後、前枠３の前側への移動と共に、回転案内部材４６が更に前向きに回転し、前枠３は回転案内部材４６上を相対的に転がってゆく。そして、例えば回転案内部材４６が第１状態までくると、その後は前枠３が回転案内部材４６側のＲ部５５上を前向きに摺動して（図７（ｃ））、下面側後端部がＲ部５５を通過すると、辺部５３上を摺動しつつ下枠材２の前側に落下する（図７（ｄ））。
【００４２】
なお、前枠３を開放する際には、回転案内部材４６と前枠３の下面３ａとの間の摩擦が小さい場合、前枠３を全閉状態から前側に引き出す際に回転案内部材４６が中間状態のまま回転しない場合もあり得る。この場合には、前枠３は回転案内部材４６により上向きに押し上げられることなく下枠材２の前端側から落下することになるが、特に問題はない。なおこの場合は、回転案内部材４６はバネ部材４７の付勢により、前向きに移動する前枠３の後を追って中間状態から前向きに揺動し、前枠３が開放されたときには第１状態に移動する。
【００４３】
以上説明したように、本実施形態では、下枠材２の上部側に、少なくとも前枠３を閉じる際にその前枠３に押されて左右方向の回転軸４５廻りに回動しつつ前枠３の下面３ａを下枠材２の上面２ａの上側に押し上げる回転案内部材４６を備えているため、前枠３を持ち上げつつ回転させる等の煩わしい手順を踏むことなく前枠３の開閉をスムーズに行うことが可能となる。また、前枠３側にはその後方に突起するものがないため、前枠３を開放した状態での作業が阻害されることもない。
【００４４】
回転案内部材４６は、前枠３を閉じる際にその前枠３の下面側後端部が当接する当接受け部５７が下枠材２の上面２ａの前端側よりも前側で且つ回転軸４５よりも上側の位置に保持される第１状態と、その略全体が前記下枠材２の内側に収容されて少なくとも下枠材２の上面２ａよりも上側に突出しない第２状態との間で上向きに揺動自在に構成され、その揺動時に、当接受け部５７が下枠材２の上面側前端部の外側を通過するように構成されているため、前枠３を閉じる際に前枠３の下面側後端部が下枠材２の上面側前端部に当接することなく下枠材２の上側に案内されると共に、前枠３が閉じた状態では回転案内部材４６は下枠材２の内側に収容されて邪魔になることもない。
【００４５】
回転案内部材４６を第２状態から第１状態に向けて付勢する付勢手段４７を備えているため、前枠３を開放した状態では必ず回転案内部材４６が第１状態に保持され、前枠３を閉じる際にわざわざ回転案内部材４６を第１状態まで回転させる手間を省くことができる。
【００４６】
回転案内部材４６は、第２状態ではその略全体が下枠材２の前面側よりも後方に収容されるように構成されているため、前枠３を閉じた状態では回転案内部材４６は下枠材２の前側に突出せず、見栄えを損なうこともない。
【００４７】
回転案内部材４６を下枠材２の上面２ａにおけるヒンジ４とは反対側の端部近傍に設けているため、ヒンジ４に近い位置に設ける場合と比べて回転案内部材４６側の耐荷重を小さくすることができる。
【００４８】
前枠３の下面３ａ側で且つ回転案内部材４６に対応する部分よりもヒンジ４側に、その後部側を後上がりの傾斜状に切り欠いた傾斜案内面６３を形成しているため、前枠３を閉じる際にその下面側後端部が回転案内部材４６に当接するまでの間、前枠３のヒンジ４側の下端部を下枠材２の上側にスムーズに案内させることができる。
【００４９】
前枠３の下面３ａ側の少なくとも回転案内部材４６の当接部分に補強板６１を装着しているため、回転案内部材４６による前枠３側の摩耗や損傷を極力小さくすることができ、また摩耗等が進行した場合には補強板６１のみの交換で対応することができる。
【００５０】
回転案内部材４６を下枠材２に対して着脱自在に装着しているため、回転案内部材４６側の摩耗が進行したり破損した場合には回転案内部材４６側のみを容易に交換することができる。
【００５１】
図８は本発明の第２の実施形態を例示し、第１の実施形態における前枠３側の構成を一部変更した例を示している。
【００５２】
本実施形態では、前枠３側の補強板６１の前側に上向きの凹部６４を設けている。この凹部６４は、前枠３を閉じたとき、例えばその前縁側６４ａに回転案内部材４６側のＲ部５６が後側から係合した状態（中間状態）となり、且つその状態で回転案内部材４６側の前縁側（辺部５１）が本体枠４４の前縁側、即ち下枠材２の前面側と略一致するように形成されている。
【００５３】
このような構成とすることで、前枠３を閉じたとき、回転案内部材４６の前縁側の位置が本体枠４４の前縁側と略一致するため、下枠材２の前面側の凹凸が少なくなり、遊技機本体の見栄えがよくなるという利点がある。
【００５４】
図９〜図１１は本発明の第３の実施形態を例示し、回転案内部材４６の形状を変更した例を示している。なお、本体枠４４は第１の実施形態と同様の構成を採用している。
【００５５】
図９に示すように、本実施形態の回転案内部材４６は、円弧部７１を備えた略扇形に形成されており、円弧部７１に対向する角部７２の内角は９０°又はそれよりも小さな所定角度に形成されている。角部７２はＲ状に形成されており（以下、Ｒ部７２という）、回転案内部材４６はこのＲ部７２の内側で回転軸４５により回動自在に保持されており、例えばそのＲ部７２を挟む一方の辺部７３が本体枠４４の連結板部４３の前部上面側に当接する第１状態（図９に実線で示す）と、他方の辺部７４が連結板部４３の後部上縁側に当接する第２状態との間で上向きに揺動可能となっている。円弧部７１は、例えば回転軸４５を中心とする円弧状に形成されている。
【００５６】
また、回転案内部材４６は、第１の実施形態と略同様のバネ部材（付勢手段）により第２状態から第１状態に向けて付勢されている。
【００５７】
辺部７３上には、回転案内部材４６が第１状態にあるとき、即ち辺部７３が連結板部４３の前部上面側に当接した状態のときに連結板部４３の前縁側に当接して回転案内部材４６の前側への回動を規制するストッパー７５が、突起状に一体形成されている。なお、辺部７３が連結板部４３の前部上面側に当接することにより回転案内部材４６の前側への回動を十分に規制することができる場合にはストッパー７５は省略してもよい。
【００５８】
円弧部７１は、その半径（回転軸４５からの距離）が、回転軸４５から下枠材２の上面側前端部までの距離よりも長く形成されている。即ち、回転案内部材４６が第１状態と第２状態との間で揺動移動する際には、円弧部７１は下枠材２の上面側前端部の外側を移動する。
【００５９】
更に、回転案内部材４６は、第１状態にあるとき、円弧部７１の大部分が下枠材２の前面側よりも前側に突出した状態となり、前枠３を閉じる際にはその前枠３の下面側後端部がこの円弧部７１に当接するようになっている。なお、この当接位置は必ず回転軸４５よりも上側となるように、回転軸４５の位置が設定されている。また、回転案内部材４６が第２状態にあるときには、回転案内部材４６はその略全体が下枠材２２内に収容されて少なくとも下枠材２の上面側よりも上側に突出しないようになっている。
【００６０】
円弧部７１上には、切り欠き状の当接受け部５７が形成されている。この当接受け部５７は、前枠３を閉じる際にその前枠３の下面側後端部が最初に当接する位置と略同じかそれよりも上側（辺部７４側）に設けられている。
【００６１】
この回転案内部材４６に対応する前枠３側の補強板６１には、第２の実施形態と同様、その前側に上向きの凹部６４を設けている。この凹部６４は、前枠３を閉じたとき、例えばその前縁側６４ａに回転案内部材４６側の円弧部７１と辺部７３との間のＲ状の角部（以下、Ｒ部７６という）が後側から係合した状態（中間状態、図９に二点鎖線で示す）となるように形成されている。なお、前枠３側には第１の実施形態と同様の傾斜案内部６３が設けられている。
【００６２】
続いて、前枠３の開閉時の動作状態について図９及び図１０を参照しつつ説明する。図９に実線で示すように、前枠３を前側に開放した状態では、ヒンジ４のガタと前枠３の重量により、前枠３の開閉端側の下面３ａは閉鎖時の位置（下枠材２の上面側の位置）よりも垂れ下がった状態となる。
【００６３】
また、下枠材２側の案内ユニット４１は、回転案内部材４６がバネ部材４７の付勢により第１状態に保持され、その当接受け部５７が下枠材２の前側に位置した状態となっている。
【００６４】
この状態から前枠３を徐々に閉じてゆくと、前枠３の下面３ａがヒンジ４側から徐々に下枠材２の上面２ａ側に重なってゆく。このとき、前枠３の下面３ａには傾斜案内面６３が形成されているため、前枠３の下面３ａは下枠材２の上面２ａに殆ど擦れることはなく、また擦れたとしても傾斜案内面６３に案内されてスムーズに乗り上げてゆく。
【００６５】
そして、前枠３を所定位置まで閉じたとき、前枠３の下面側後端部が回転案内部材４６の円弧部７１上の例えば当接受け部５７に直接当接（係合）し、又はそれよりも下側（辺部７３側）に当接した後、上向きに摺動して当接受け部５７に係合する（図１０（ａ））。このとき、回転案内部材４６はその当接受け部５７に後ろ向きの力を受ける。当接受け部５７は回転軸４５よりも高い位置にあるため、その後ろ向きの力によって回転案内部材４６には回転軸４５廻りのモーメントが発生し、回転案内部材４６は前枠３の移動に伴って後ろ向きに回転を始める。
【００６６】
回転案内部材４６が後ろ向きに回転を始めると、当接受け部５７の位置が徐々に上昇し、それによって前枠３はその当接受け部５７から上向きの力を受ける。これにより、前枠３はその下面側後端部を当接受け部５７に支持された状態で上斜め後方に持ち上げられる（図１０（ｂ））。このとき、当接受け部５７は、下枠材２の上面側前端部の外側を移動するため、前枠３はその下面側後端部が下枠材２の上面側前端部に当接することなく下枠材２の上面２ａの上側に移動する。
【００６７】
その後、回転案内部材４６が更に回転し、当接受け部５７がその移動経路の最上位位置を過ぎると、例えば前枠３が回転案内部材４６上を相対的に転がって、前枠３と回転案内部材４６との当接位置が徐々に移動する。即ち、回転案内部材４６側の支持位置が当接受け部５７からそれよりも前側に徐々に移動し、前枠３側の被支持位置がその下面３ａを徐々に前向きに移動する。
【００６８】
回転案内部材４６が第２状態に達すると、前枠３は回転案内部材４６のＲ部７６上を後ろ向きに摺動する（図１０（ｃ））。そして、補強板６１側の凹部６４に回転案内部材４６側のＲ部７６が嵌合して前枠３が全閉位置に達すると、回転案内部材４６はバネ部材４７の付勢によりそのＲ部７６が補強板６１側の凹部６４の前縁側６４ａに当接するまで前向きに回転し、停止する。
【００６９】
このように、本実施形態では、前枠３を閉じる際に、下枠材２側の回転案内部材４６が前枠３の下端側に押されて後ろ向きに回転する際にその前枠３を上向きに押し上げるように作用するため、前枠３側の構成を複雑化することなく、前枠３の開閉をスムーズに行うことが可能となる。また、前枠３側にはその後方に突起するものがないため、前枠３を開放した状態での作業が阻害されることもない。
【００７０】
更に、前枠３が当接する部分が円弧状（円弧部７１）に形成されているため、前枠３が下枠材２の上側に乗り上げた後、前枠３を上下方向にがたつかせることなく全閉位置までスムーズに案内することができる。
【００７１】
前枠３を開放する場合には、前枠３及び回転案内部材４６は例えば次のように動作する。即ち、前枠３を全閉状態から開方向に引き出すと、回転案内部材４６は、前枠３の前側への移動と共に中間状態から前向きに回転を始める。これにより、前枠３側は回転案内部材４６側の円弧部７１から上向きの力を受けて上斜め前方に持ち上げられる（図１１（ａ）→（ｂ））。
【００７２】
その後、前枠３の前側への移動と共に、回転案内部材４６が更に前向きに回転し、前枠３は回転案内部材４６上を相対的に転がってゆく。そして、例えば回転案内部材４６が第１状態までくると、その後は前枠３が回転案内部材４６側のＲ部７７（円弧部７１と辺部７４との間のＲ状の角部）上を前向きに摺動して（図１１（ｃ））、下面側後端部がＲ部７７を通過すると、円弧部７１上を摺動しつつ下枠材２の前側に落下する（図１１（ｄ））。
【００７３】
図１２は本発明の第４の実施形態を例示し、第３の実施形態を変更して、当接受け部５７を円弧部７１上の所定範囲に複数個形成した例を示している。このような構成とすることで、前枠３の開放時の垂れ下がり量が変化しても、前枠３側の下面側後端部を何れかの当接受け部５７に確実に係合させて回転案内部材４６を後ろ向きに回転させることが可能となる。
【００７４】
以上、本発明の実施形態について詳述したが、本発明はこの実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲で種々の変更が可能である。例えば、回転案内部材４６は、実施形態で示したような略三角形状、略扇形状以外の種々の形状を採用できる。例えば、第１の実施形態においては回転案内部材４６の各辺部５１〜５３を略直線状に形成したが、円弧状等の曲線状に形成してもよい。
【００７５】
回転案内部材４６を略扇形以外の形状に形成した場合でも、当接受け部５７を切り欠き状に形成してもよい。また、当接受け部５７は前枠３と回転案内部材４６との滑りを抑制できるものであればよく、例えば突起状に形成してもよい。
【００７６】
その他、本発明は、パチンコ機だけでなくアレンジボール機や雀球遊技機等のその他の弾球遊技機をはじめ、スロットマシン等の各種遊技機において同様に実施可能である。
【００７７】
例えば一般的なスロットマシンのように外枠の前側下部に下枠材が設けられていないものであっても、外枠の下側の横枠材の前側等に前枠の下面に対向する対向面を有するものであれば本発明を適用することができ、例えば横枠材の前側等に実施形態と同様の回転案内部材４６を設けることで実施形態と同様の効果が期待できる。
【００７８】
【発明の効果】
以上説明したように、本発明は、矩形状の外枠１と、該外枠１に対して縦方向のヒンジ４により開閉自在に取り付けられる前枠３とを備え、該外枠１には、前枠３を閉じた状態で該前枠３の下面３ａに対向する対向面２ａを形成した遊技機において、外枠１側に、前枠３を閉じる際にその前枠３に押されて左右方向の回転軸４５廻りに回動しつつ前枠３の下面３ａを対向面２ａの上側に押し上げる回転案内部材４６を備え、該回転案内部材４６は、前枠３を閉じる際にその前枠３の下面側後端部が当接する当接受け部５７が対向面２ａの前端側よりも前側で且つ回転軸４５よりも上側の位置に保持される第１状態と、その略全体が対向面２ａの下側に収容される第２状態との間で上向きに揺動自在に構成され、その揺動時に、当接受け部５７が対向面２ａの前端の外側を通過するように構成されているため、前枠３の後ろ側に大きな突起物を設けることなく、また例えば前枠３を持ち上げるなどの煩わしい手順を踏むことなく前枠３の開閉をスムーズに行うことが可能である。

BACKGROUND OF THE INVENTION
The present invention includes a rectangular outer frame and a front frame that can be freely opened and closed with respect to the outer frame by a vertical hinge. The outer frame has a lower surface of the front frame with the front frame closed. The present invention relates to various game machines such as a pachinko machine, an arrange ball machine, a slot machine, etc., which have a facing surface facing each other.
[0002]
[Prior art]
A gaming machine such as a pachinko machine, an arrangement ball machine, or a slot machine includes a rectangular outer frame and a front frame that is attached to the outer frame by a vertical hinge so as to be opened and closed. In general, a facing surface facing the lower surface of the front frame is formed in a state in which the front frame is closed on the lower frame member in the left-right direction fixed to the lower portion of the front side.
[0003]
In this type of gaming machine, on the back side of the front frame, a game board, a payout device, a launching means, etc., to which various winning means, display means, etc. are attached, are attached, and on the front side, the front side of the game board is attached. A glass door to cover, a front plate on which an upper plate for storing game balls is mounted, a lower plate for storing excess balls, and the like are attached.
[0004]
As described above, the front frame has a large weight because a large number of components are attached, and when the front frame is opened and closed, an excessive load is applied to the hinge supporting the front frame. As a result, when the front frame is opened, the open / close end side (the end opposite to the hinge) of the front frame hangs down from the outer frame side facing surface (for example, the upper surface of the lower frame material), When closing the front frame, simply rotating the front frame around the hinge prevents the lower rear edge side of the front frame from interfering with the front part of the opposing surface on the outer frame side. Troublesome work such as rotating the frame while lifting it was necessary.
[0005]
Therefore, conventionally, a guide wheel is provided on the front frame side, and when the front frame is closed, the guide wheel rides on the opposing surface on the outer frame side, so that the lower end portion of the front frame and the outer frame are not rubbed. A device that can open and close the front frame smoothly is known (see, for example, Patent Document 1).
[Patent Document 1]
JP2002-85762
[0006]
[Problems to be solved by the invention]
In a conventional gaming machine provided with such a guide wheel, although the opening and closing operation can be performed smoothly without lifting the front frame, the guide wheel protrudes greatly to the rear side of the front frame. There is a drawback that the work efficiency is lowered because it interferes with the work in a state where the door is opened.
[0007]
In addition, the configuration on the front frame side is further complicated, and the assembly process is complicated.
[0008]
The present invention has been made in view of the above circumstances, and an object thereof is to provide a gaming machine capable of smoothly opening and closing the front frame without providing a large protrusion on the rear side of the front frame. .
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the present invention includes a rectangular outer frame 1 and a front frame 3 attached to the outer frame 1 by a vertical hinge 4 so as to be freely opened and closed. In the gaming machine in which the opposed surface 2a facing the lower surface 3a of the front frame 3 is formed with the front frame 3 closed, the front frame 3 is closed when the front frame 3 is closed on the outer frame 1 side. And a rotation guide member 46 that pushes the lower surface 3a of the front frame 3 to the upper side of the opposing surface 2a while being rotated around the rotation shaft 45 in the left-right direction. In the rotation guide member 46, when the front frame 3 is closed, the contact receiving portion 57 with which the rear end on the lower surface side of the front frame 3 abuts is on the front side of the front end side of the facing surface 2a and the rotation shaft. 45 is configured to be swingable upward between a first state held at a position above 45 and a second state in which substantially the whole is housed below the facing surface 2a. The contact receiving part 57 is configured to pass outside the front end of the facing surface 2a. Is.

[0017]
As shown in FIG. 2, a back mechanism plate 28 that presses and fixes the game board 12 from the back side is attached to the back side of the front frame 3 so as to be freely opened and closed. An opening 28a is formed in a substantially central portion of the back mechanism plate 28, and a game ball tank 29 and a tank rail 30 are provided on the upper side thereof, and a payout connected to the downstream side of the tank rail 30 on one side in the left-right direction. The apparatus 31 is provided with a passage unit 32 on the lower side. The game ball paid out from the payout device 31 from the game ball tank 29 via the tank rail 30 is discharged to the upper plate 8 via the passage unit 32.
[0018]
A back cover 33 that covers the back side of the game board 12 is fitted into the opening 28 a of the back mechanism plate 28. The back cover 33 is detachably mounted with substrate cases 34, 35, 36, etc., each housing a main control board, a lamp control board, a sound control board, and the like. Further, on the back mechanism plate 28 on the lower side of the back cover 33, a substrate case 37 and the like housing a power supply substrate, a payout control substrate and the like are detachably mounted.
[0019]
On the upper surface 2 a side of the lower frame member 2, a guide unit 41 is provided in the vicinity of the end opposite to the hinge 4. As shown in FIG. 4 and the like, the guide unit 41 is integrally provided with a pair of left and right opposing side plate portions 42, for example, rectangular plates, and a connecting plate portion 43 that connects the lower end portions of the side plate portions 42 to the left and right. A main body frame 44, a left and right rotation shaft 45 spanned between the left and right side plate portions 42 of the main body frame 44, a rotation guide member 46 rotatably supported by the rotation shaft 45, and the rotation guide A spring member (biasing means) 47 such as a coil spring for urging the member 46 in a predetermined direction is provided, and is detachably mounted in an attachment groove 48 provided on the upper surface 2a side of the lower frame member 2.
[0020]
The main body frame 44 is made of, for example, metal, and the width in the front-rear direction of the side plate portion 42 is formed substantially the same as the plate thickness of the lower frame member 2. The mounting groove 48 is formed in the front-rear direction from the back surface side to the front surface side of the lower frame member 2, and the depth from the upper surface 2a of the lower frame member 2 is the vertical width of the main body frame 44 (side plate portion 42). The width in the left-right direction is substantially the same as the width in the left-right direction of the main body frame 44 (connecting plate portion 43). That is, when the main body frame 44 is fitted into the mounting groove 48, the side plate portion 42 is aligned with the left and right side surfaces of the mounting groove 48, and the connecting plate portion 43 is aligned with the bottom surface of the mounting groove 48.
[0021]
For example, a metal rotating shaft 45 is attached to the front lower portion of the main body frame 44 with both end sides fixed to the side plate portion 42.
[0022]
Further, for example, on the rear side of the main body frame 44, a fixing plate portion 49 is integrally formed from the rear edge portions of the left and right side plate portions 42 along the back surface side of the lower frame material 2, and the main body frame 44 is The fixing plate portion 49 is fixed to the lower frame member 2 by being fixed with a mounting screw 50.
[0023]
Note that the fixing plate portion 49 may be provided on the upper side of the main body frame 44 along the upper surface 2a side of the lower frame material 2, for example. However, in this case, there is an attachment recess for embedding the fixing plate portion 49 on the upper surface 2a side of the lower frame material 2 so that the upper surface side of the fixing plate portion 49 does not protrude above the upper surface 2a of the lower frame material 2. It must be formed. Further, the fixed plate portion 49 may be provided, for example, on the front side of the main body frame 44 along the front side of the lower frame member 2.
[0024]
When the front frame 3 is closed, the rotation guide member 46 is pushed to the lower end side of the front frame 3 and rotates around the rotation shaft 45, and the opening / closing end side of the front frame 3 is pushed upward to lower the lower surface of the front frame 3. This is for preventing rubbing between the side rear end portion and the front end portion on the upper surface side of the lower frame member 2, and has three substantially straight side portions 51 to 53 as shown in FIG. Three corners sandwiched between the two side parts 51 to 53 are formed in a substantially triangular shape in a side view formed in an R shape (hereinafter referred to as R parts 54 to 56). The rotation guide member 46 is made of, for example, metal, and needs to be formed to have a plate thickness (dimension in the left-right direction) that can obtain sufficient strength to withstand the weight of the front frame 3.
[0025]
Further, as shown in FIG. 5, the rotation guide member 46 is rotatably held by the rotation shaft 45 in the vicinity of the R portion 54. For example, one side portion 51 side sandwiching the R portion 54 is the main body frame 44. Between the first state (shown by a solid line in FIG. 5) and the second state in which the other side portion 52 is in contact with the rear upper edge side of the connecting plate portion 43. It can swing upward.
[0026]
When the rotation guide member 46 is in the first state, at least substantially the entire side portion 53 facing the R portion 54 protrudes forward from the front side of the lower frame member 2 (the front end side of the upper surface 2a), and the front When the frame 3 is closed, the rear end portion on the lower surface side of the front frame 3 comes into contact with one point on the side portion 53 (hereinafter referred to as a contact receiving portion 57).
[0027]
In the first state, the side portion 53 is located on the front side of the front surface side (front end side of the upper surface 2a) of the lower frame member 2 and on the upper side of the rotating shaft 45 in the first state. The distance from the rotation shaft 45 to the contact receiving portion 57 is longer than the distance from the rotation shaft 45 to the front end portion on the upper surface side of the lower frame member 2. That is, when the rotation guide member 46 swings and moves between the first state and the second state, the contact receiving portion 57 always moves outside the front end portion on the upper surface side of the lower frame member 2.
[0028]
Further, when the rotation guide member 46 is in the first state, the side portion 53 is in a state slightly lower than the vertical, for example, and the R portion 55 protrudes slightly above the upper surface side of the lower frame member 2. Become. Further, when the rotation guide member 46 is in the second state, the rotation guide member 46 is substantially entirely accommodated in the lower frame member 22 so as not to protrude at least above the upper surface 2a of the lower frame member 2. Yes.
[0029]
The spring member 47 is attached to the rotating shaft 45, for example, and one end side 47a thereof is engaged with the main body frame 44 side and the other end side 47b thereof is engaged with the rotation guide member 46 side. Energizing towards the first state. In a state where the front frame 3 is closed, the rotation guide member 46 is in an intermediate state between the second state and the first state, that is, at one position (for example, the R portion 56 or The vicinity thereof is held in an intermediate state (indicated by a two-dot chain line in FIG. 5) in contact with the lower surface 3a of the front frame 3.
[0030]
On the lower surface 3a side of the front frame 3, a reinforcing plate 61 is provided corresponding to the rotation guide member 46 on the lower frame material 2 side, as shown in FIG. The reinforcing plate 61 is formed in an L-shaped cross section that covers a portion from the lower surface side front end portion of the front frame 3 through the rear end portion to the back surface side, and is detachably attached to the front frame 3 by a mounting screw 62 or the like. It is installed.
[0031]
Further, the guide is obtained by cutting the rear side of the front frame 3 to the rear side of the lower side 3a of the front frame 3 and the hinge 4 side of the portion corresponding to the rotation guide member 46 (that is, the mounting portion of the reinforcing plate 61). An inclined surface 63 is formed. When the front frame 3 is opened and the lower surface 3a on the opening / closing end side of the inclined guide surface 63 hangs down from the upper surface 2a of the lower frame member 2, the rear edge side 63a becomes substantially horizontal. 63a is formed so as to be gradually higher than the lower surface side of the front frame 3 from the vicinity of the hinge 4 toward the reinforcing plate 61 side. Further, the inclination guide surface 63 has a substantially constant inclination angle in the front-rear direction, and the position of the front edge side 63b gradually moves forward from the hinge 4 side toward the reinforcing plate 61 side. It is formed in an elongated triangle shape.
[0032]
Next, an operation state when the front frame 3 is opened and closed will be described with reference to FIGS. 5 and 6. As shown by a solid line in FIG. 5, in a state where the front frame 3 is opened to the front side, the lower surface 3a on the open / close end side of the front frame 3 is in the closed position (lower frame) due to the backlash of the hinge 4 and the weight of the front frame 3. It is in a state of hanging down from the position of the upper surface 2a of the material 2.
[0033]
Further, in the guide unit 41 on the lower frame member 2 side, the rotation guide member 46 is held in the first state by the bias of the spring member 47, and the side portion 53 side protrudes to the front side of the lower frame member 2. .
[0034]
When the front frame 3 is gradually closed from this state, the lower surface 3a side of the front frame 3 gradually overlaps the upper surface 2a side of the lower frame material 2 from the hinge 4 side. At this time, since the inclined guide surface 63 is formed on the lower surface 3 a side of the front frame 3, the lower surface 3 a side of the front frame 3 hardly rubs against the upper surface 2 a side of the lower frame material 2. It is guided by the inclined guide surface 63 and rides smoothly.
[0035]
When the front frame 3 is closed to a predetermined position, the rear end on the lower surface side of the front frame 3 comes into contact with a predetermined position (contact receiving portion 57) on the side portion 53 of the rotation guide member 46 (FIG. 6A). )). At this time, the rotation guide member 46 receives a backward force from the contact receiving portion 57. Since the contact receiving portion 57 is at a position higher than the rotation shaft 45, a moment around the rotation shaft 45 is generated in the rotation guide member 46 due to the backward force, and the rotation guide member 46 moves to the rear of the front frame 3. As it moves, it begins to rotate backwards.
[0036]
When the rotation guide member 46 starts to rotate backward, the position of the contact receiving portion 57 gradually rises, whereby the front frame 3 receives an upward force from the contact receiving portion 57. As a result, the front frame 3 is lifted obliquely upward and rearward in a state where the rear end portion on the lower surface side is supported by the contact receiving portion 57 (FIG. 6B). At this time, since the abutment receiving portion 57 moves outside the front end portion on the upper surface side of the lower frame member 2, the rear end portion of the lower surface side of the front frame 3 abuts on the front end portion on the upper surface side of the lower frame member 2. It moves to the upper part of the lower frame material 2 without.
[0037]
Thereafter, when the rotation guide member 46 further rotates and the contact receiving portion 57 passes the uppermost position of the movement path, for example, the front frame 3 rolls relatively on the rotation guide member 46 and rotates with the front frame 3. The contact position with the guide member 46 gradually moves (FIG. 6C). That is, the support position on the rotation guide member 46 side gradually moves forward from the contact receiving portion 57, and the supported position on the front frame 3 side gradually moves forward on the lower surface 3a.
[0038]
Then, when the lower surface 3a of the front frame 3 eventually comes into contact with the upper surface 2a of the lower frame material 2, the front frame 3 thereafter moves to the fully closed position while sliding on the upper surface 2a of the lower frame material 2 (FIG. 6). (D)). At that time, the rotation guide member 46 is held in an intermediate state in which one position (for example, the R portion 56 or the vicinity thereof) on the edge portion is brought into contact with the lower surface 3 a of the front frame 3 by the biasing of the spring member 47. The

Thus, in this embodiment, when the front frame 3 is closed, when the rotation guide member 46 on the lower frame member 2 side is pushed by the rear end portion on the lower surface side of the front frame 3 and rotates backward, The front frame 3 can be smoothly opened and closed without taking a troublesome procedure such as rotating the front frame 3 while lifting the front frame 3 because it acts to guide the upper side 3a to the upper side 2a of the lower frame member 2 while pushing the 3 upward. Is possible. Moreover, since there is no thing protruding on the front frame 3 side behind, the operation | work in the state which open | released the front frame 3 is not inhibited.
[0040]
Next, when opening the front frame 3, the front frame 3 and the rotation guide member 46 operate | move like FIG. 7, for example. That is, when the front frame 3 is pulled out from the fully closed state in the opening direction, the rotation guide member 46 is moved along with the movement of the front frame 3 to the front side when the friction with the lower surface 3a of the front frame 3 is large to some extent. Start to rotate forward from the state. As a result, the front frame 3 side receives an upward force from the R portion 56 on the rotation guide member 46 side and is lifted diagonally upward (FIGS. 7A to 7B).
[0041]
Thereafter, as the front frame 3 moves to the front side, the rotation guide member 46 further rotates forward, and the front frame 3 rolls relatively on the rotation guide member 46. For example, when the rotation guide member 46 reaches the first state, the front frame 3 then slides forward on the R portion 55 on the rotation guide member 46 side (FIG. 7 (c)), and the lower surface side rear end. When the part passes through the R part 55, it slides on the side part 53 and falls to the front side of the lower frame member 2 (FIG. 7D).
[0042]
When opening the front frame 3, if the friction between the rotation guide member 46 and the lower surface 3a of the front frame 3 is small, the rotation guide member 46 is used when the front frame 3 is pulled out from the fully closed state to the front side. In some cases, the intermediate state does not rotate. In this case, the front frame 3 falls from the front end side of the lower frame member 2 without being pushed upward by the rotation guide member 46, but there is no particular problem. In this case, the rotation guide member 46 swings forward from the intermediate state following the front frame 3 that moves forward by the urging of the spring member 47, and when the front frame 3 is opened, the rotation guide member 46 enters the first state. Moving.
[0043]
As described above, in the present embodiment, at least the front frame 3 is pushed on the upper side of the lower frame member 2 when the front frame 3 is closed, and the front frame 3 rotates around the rotation shaft 45 in the left-right direction. 3 is provided with a rotation guide member 46 that pushes up the lower surface 3a of the lower frame 3 to the upper side of the upper surface 2a of the lower frame member 2, so that the front frame 3 can be opened and closed smoothly without taking a troublesome procedure such as rotating the front frame 3 Can be done. Moreover, since there is no thing protruding on the front frame 3 side behind, the operation | work in the state which open | released the front frame 3 is not inhibited.
[0044]
In the rotation guide member 46, when the front frame 3 is closed, the contact receiving portion 57 with which the lower end on the lower surface side of the front frame 3 comes into contact is more forward than the front end side of the upper surface 2a of the lower frame member 2, and Between a first state held at a position above the upper frame and a second state in which substantially the whole is accommodated inside the lower frame member 2 and does not protrude at least above the upper surface 2a of the lower frame member 2. Since the contact receiving portion 57 is configured to pass outside the front end portion on the upper surface side of the lower frame material 2 when swinging, the front receiving portion 57 is closed when the front frame 3 is closed. The rear end portion on the lower surface side of the frame 3 is guided to the upper side of the lower frame member 2 without contacting the front end portion on the upper surface side of the lower frame member 2, and the rotation guide member 46 is in a state where the front frame 3 is closed. It is housed inside the material 2 and does not get in the way.
[0045]
Since the urging means 47 for urging the rotation guide member 46 from the second state to the first state is provided, the rotation guide member 46 is always held in the first state when the front frame 3 is opened, and the front The trouble of rotating the rotation guide member 46 to the first state when the frame 3 is closed can be saved.
[0046]
In the second state, the rotation guide member 46 is configured to be accommodated behind the front side of the lower frame member 2 in the second state. Therefore, the rotation guide member 46 is lower when the front frame 3 is closed. It does not protrude to the front side of the frame member 2 and does not impair the appearance.
[0047]
Since the rotation guide member 46 is provided in the vicinity of the end on the opposite side of the hinge 4 on the upper surface 2 a of the lower frame member 2, the load resistance on the rotation guide member 46 side is reduced compared to the case where it is provided near the hinge 4. can do.
[0048]
Since an inclined guide surface 63 is formed on the lower surface 3a side of the front frame 3 and closer to the hinge 4 side than the portion corresponding to the rotation guide member 46, the rear portion side thereof is cut out in an upwardly inclined manner. The lower end portion on the hinge 4 side of the front frame 3 can be smoothly guided to the upper side of the lower frame member 2 until the lower end of the lower surface side abuts against the rotation guide member 46 when the 3 is closed.
[0049]
Since the reinforcing plate 61 is attached to at least the contact portion of the rotation guide member 46 on the lower surface 3a side of the front frame 3, wear and damage on the front frame 3 side due to the rotation guide member 46 can be minimized. When wear or the like progresses, it can be dealt with by replacing only the reinforcing plate 61.
[0050]
Since the rotation guide member 46 is detachably attached to the lower frame member 2, when wear on the rotation guide member 46 side progresses or breaks, only the rotation guide member 46 side can be easily replaced. it can.
[0051]
FIG. 8 illustrates the second embodiment of the present invention and shows an example in which the configuration on the front frame 3 side in the first embodiment is partially changed.
[0052]
In the present embodiment, an upward concave portion 64 is provided on the front side of the reinforcing plate 61 on the front frame 3 side. When the front frame 3 is closed, the concave portion 64 is in a state (intermediate state) in which, for example, the R portion 56 on the rotation guide member 46 side is engaged with the front edge side 64a from the rear side, and the rotation guide member 46 is in that state. The front edge side (side portion 51) on the side is formed so as to substantially coincide with the front edge side of the main body frame 44, that is, the front surface side of the lower frame material 2.
[0053]
With such a configuration, when the front frame 3 is closed, the position of the front edge side of the rotation guide member 46 substantially coincides with the front edge side of the main body frame 44, so that there is little unevenness on the front side of the lower frame material 2. Therefore, there is an advantage that the appearance of the main body of the gaming machine is improved.
[0054]
9 to 11 illustrate the third embodiment of the present invention and show an example in which the shape of the rotation guide member 46 is changed. The main body frame 44 employs the same configuration as that of the first embodiment.
[0055]
As shown in FIG. 9, the rotation guide member 46 of the present embodiment is formed in a substantially fan shape having an arc portion 71, and the inner angle of the corner portion 72 facing the arc portion 71 is 90 ° or smaller. It is formed at a predetermined angle. The corner portion 72 is formed in an R shape (hereinafter referred to as the R portion 72), and the rotation guide member 46 is rotatably held by the rotation shaft 45 inside the R portion 72. For example, the R portion 72 is provided. In a first state (shown by a solid line in FIG. 9), one side 73 sandwiching the frame contacts the front upper surface of the connecting plate 43 of the main body frame 44, and the other side 74 is on the rear of the connecting plate 43. It can swing upward between the second state contacting the edge side. The circular arc part 71 is formed in the circular arc shape centering on the rotating shaft 45, for example.
[0056]
Further, the rotation guide member 46 is urged from the second state to the first state by a spring member (biasing means) substantially the same as in the first embodiment.
[0057]
On the side portion 73, when the rotation guide member 46 is in the first state, that is, when the side portion 73 is in contact with the upper surface side of the front portion of the connecting plate portion 43, it contacts the front edge side of the connecting plate portion 43. A stopper 75 that contacts and restricts the forward rotation of the rotation guide member 46 is integrally formed in a protruding shape. Note that the stopper 75 may be omitted when the side 73 is sufficiently in contact with the upper surface of the front of the connecting plate 43 to sufficiently restrict the rotation of the rotation guide member 46 to the front.
[0058]
The arc portion 71 is formed such that its radius (distance from the rotation shaft 45) is longer than the distance from the rotation shaft 45 to the front end portion on the upper surface side of the lower frame member 2. That is, when the rotation guide member 46 swings and moves between the first state and the second state, the arc portion 71 moves outside the front end portion on the upper surface side of the lower frame member 2.
[0059]
Further, when the rotation guide member 46 is in the first state, most of the arc portion 71 protrudes forward from the front side of the lower frame member 2, and when the front frame 3 is closed, the front frame 3 The rear end portion of the lower surface side of this is in contact with the arc portion 71. The position of the rotating shaft 45 is set so that the contact position is always above the rotating shaft 45. Further, when the rotation guide member 46 is in the second state, the rotation guide member 46 is substantially entirely accommodated in the lower frame member 22 so as not to protrude at least above the upper surface side of the lower frame member 2. Yes.
[0060]
On the arc portion 71, a notch-shaped contact receiving portion 57 is formed. The contact receiving portion 57 is provided at substantially the same position as the position where the lower end of the front frame 3 is first contacted when the front frame 3 is closed or on the upper side (side 74 side). .
[0061]
Similar to the second embodiment, the reinforcing plate 61 on the front frame 3 side corresponding to the rotation guide member 46 is provided with an upward concave portion 64 on the front side thereof. When the front frame 3 is closed, the concave portion 64 has, for example, an R-shaped corner portion (hereinafter referred to as an R portion 76) between the arc portion 71 and the side portion 73 on the rotation guide member 46 side on the front edge side 64 a. It is formed so as to be engaged from the rear side (intermediate state, indicated by a two-dot chain line in FIG. 9). In addition, the same inclination guide part 63 as 1st Embodiment is provided in the front frame 3 side.
[0062]
Next, an operation state when the front frame 3 is opened and closed will be described with reference to FIGS. 9 and 10. As shown by a solid line in FIG. 9, in a state where the front frame 3 is opened to the front side, the lower surface 3a on the open / close end side of the front frame 3 is in the closed position (lower frame) due to the backlash of the hinge 4 and the weight of the front frame 3. It is in a state of hanging down from the position on the upper surface side of the material 2.
[0063]
Further, the guide unit 41 on the lower frame member 2 side is such that the rotation guide member 46 is held in the first state by the bias of the spring member 47 and the contact receiving portion 57 is located on the front side of the lower frame member 2. It has become.
[0064]
When the front frame 3 is gradually closed from this state, the lower surface 3a of the front frame 3 gradually overlaps the upper surface 2a side of the lower frame member 2 from the hinge 4 side. At this time, since the inclined guide surface 63 is formed on the lower surface 3a of the front frame 3, the lower surface 3a of the front frame 3 hardly rubs against the upper surface 2a of the lower frame material 2, and even if rubbed, the inclined guide surface is provided. It is guided smoothly by the surface 63 and rides smoothly.
[0065]
When the front frame 3 is closed to a predetermined position, the lower end of the front frame 3 directly contacts (engages) with, for example, the contact receiving portion 57 on the arc portion 71 of the rotation guide member 46, or After contacting the lower side (side 73 side), it slides upward and engages the contact receiving portion 57 (FIG. 10A). At this time, the rotation guide member 46 receives a backward force from the contact receiving portion 57. Since the contact receiving portion 57 is at a position higher than the rotation shaft 45, a moment around the rotation shaft 45 is generated in the rotation guide member 46 due to the backward force, and the rotation guide member 46 is moved along with the movement of the front frame 3. And start turning backwards.
[0066]
When the rotation guide member 46 starts to rotate backward, the position of the contact receiving portion 57 gradually rises, whereby the front frame 3 receives an upward force from the contact receiving portion 57. As a result, the front frame 3 is lifted upward and obliquely rearward with its lower surface side rear end supported by the contact receiving portion 57 (FIG. 10B). At this time, since the abutment receiving portion 57 moves outside the front end portion on the upper surface side of the lower frame member 2, the rear end portion of the lower surface side of the front frame 3 contacts the front end portion on the upper surface side of the lower frame member 2. Instead, it moves to the upper side of the upper surface 2a of the lower frame member 2.
[0067]
Thereafter, when the rotation guide member 46 further rotates and the contact receiving portion 57 passes the uppermost position of the movement path, for example, the front frame 3 rolls relatively on the rotation guide member 46 and rotates with the front frame 3. The contact position with the guide member 46 gradually moves. That is, the support position on the rotation guide member 46 side gradually moves forward from the contact receiving portion 57, and the supported position on the front frame 3 side gradually moves forward on the lower surface 3a.
[0068]
When the rotation guide member 46 reaches the second state, the front frame 3 slides backward on the R portion 76 of the rotation guide member 46 (FIG. 10C). When the R portion 76 on the rotation guide member 46 side is fitted into the recess 64 on the reinforcing plate 61 side and the front frame 3 reaches the fully closed position, the rotation guide member 46 is moved to the R portion by the bias of the spring member 47. It rotates forward and stops until 76 abuts on the front edge side 64a of the recess 64 on the reinforcing plate 61 side.
[0069]
Thus, in the present embodiment, when the front frame 3 is closed, the rotation guide member 46 on the lower frame material 2 side is pushed toward the lower end side of the front frame 3 and is rotated rearward so that the front frame 3 faces upward. Therefore, it is possible to smoothly open and close the front frame 3 without complicating the configuration of the front frame 3 side. Moreover, since there is no thing protruding on the front frame 3 side behind, the operation | work in the state which open | released the front frame 3 is not inhibited.
[0070]
Further, since the portion with which the front frame 3 abuts is formed in an arc shape (arc portion 71), after the front frame 3 rides on the upper side of the lower frame material 2, the front frame 3 is made to rattle in the vertical direction. It can be smoothly guided to the fully closed position.
[0071]
When the front frame 3 is opened, the front frame 3 and the rotation guide member 46 operate as follows, for example. That is, when the front frame 3 is pulled out from the fully closed state in the opening direction, the rotation guide member 46 starts to rotate forward from the intermediate state as the front frame 3 moves to the front side. As a result, the front frame 3 side receives an upward force from the arc portion 71 on the rotation guide member 46 side and is lifted diagonally forward (FIGS. 11A to 11B).
[0072]
Thereafter, as the front frame 3 moves to the front side, the rotation guide member 46 further rotates forward, and the front frame 3 rolls relatively on the rotation guide member 46. For example, when the rotation guide member 46 reaches the first state, the front frame 3 thereafter moves on the R portion 77 (the R-shaped corner between the arc portion 71 and the side portion 74) on the rotation guide member 46 side. Sliding forward (FIG. 11C), when the rear end on the lower surface side passes through the R portion 77, it slides on the arc portion 71 and falls to the front side of the lower frame member 2 (FIG. 11D). )).
[0073]
FIG. 12 illustrates a fourth embodiment of the present invention, and shows an example in which a plurality of contact receiving portions 57 are formed in a predetermined range on the arc portion 71 by modifying the third embodiment. With such a configuration, even if the amount of sag when the front frame 3 is opened changes, the rear end on the lower surface side on the front frame 3 side is securely engaged with any of the contact receiving portions 57. It is possible to rotate the rotation guide member 46 backward.
[0074]
As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to this embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, the rotation guide member 46 can adopt various shapes other than the substantially triangular shape and the substantially fan shape as shown in the embodiment. For example, in the first embodiment, the side portions 51 to 53 of the rotation guide member 46 are formed in a substantially linear shape, but may be formed in a curved shape such as an arc shape.
[0075]
Even when the rotation guide member 46 is formed in a shape other than a substantially sector shape, the contact receiving portion 57 may be formed in a notch shape. Further, the contact receiving portion 57 may be any member as long as it can suppress slippage between the front frame 3 and the rotation guide member 46, and may be formed in a protruding shape, for example.
[0076]
In addition, the present invention can be similarly implemented not only in pachinko machines but also in various game machines such as slot machines, including other ball game machines such as arrange ball machines and sparrow ball game machines.
[0077]
For example, even if the lower frame material is not provided at the front lower part of the outer frame as in a general slot machine, the front side of the horizontal frame material on the lower side of the outer frame is opposed to the lower surface of the front frame. The present invention can be applied as long as it has a surface. For example, the same effect as that of the embodiment can be expected by providing a rotation guide member 46 similar to that of the embodiment on the front side of the horizontal frame member.
[0078]
【The invention's effect】
As described above, the present invention includes the rectangular outer frame 1 and the front frame 3 attached to the outer frame 1 by the vertical hinge 4 so as to be freely opened and closed. In the gaming machine in which the opposed surface 2a facing the lower surface 3a of the front frame 3 is formed in a state where the front frame 3 is closed, when the front frame 3 is closed on the outer frame 1 side, A rotation guide member 46 that pushes the lower surface 3a of the front frame 3 to the upper side of the opposing surface 2a while rotating around the rotation shaft 45 in the direction. In the rotation guide member 46, when the front frame 3 is closed, the contact receiving portion 57 with which the rear end portion on the lower surface side of the front frame 3 abuts is in front of the front end side of the facing surface 2a and more than the rotation shaft 45. The first state held in the upper position and the second state in which substantially the whole is housed below the opposing surface 2a are configured to be swingable upward, and at the time of the swing, the contact receiving The portion 57 is configured to pass outside the front end of the facing surface 2a. Therefore, it is possible to smoothly open and close the front frame 3 without providing a large protrusion on the rear side of the front frame 3 and without taking a troublesome procedure such as lifting the front frame 3.
