【０００１】
【発明の属する技術分野】
本発明は、パチンコ球を貯留する球受皿の底壁に球抜き孔を開設し、該球受皿の底壁の下面に設けたシャッター板を摺動又は回動させることにより球抜き孔を開放して球抜きするようにしたパチンコ機における球受皿の球抜き装置に関し、特に球受皿に貯留されるパチンコ球の球重量によりシャッター板を球抜き孔を開放する位置に係止保持させるようにしたり、球抜き孔を閉じる位置に自動復帰させるようにしたパチンコ機における球受皿の球抜き装置に関するものである。
【０００２】
【従来の技術】
従来、球受皿の皿部に貯留されるパチンコ球を利用してシャッター板を球抜き孔を開放する位置に係止保持するようにした球受皿の球抜き装置は知られている（例えば特開平９−８４９３６号公報参照）。
【０００３】
【発明が解決しようとする課題】
従来の球受皿の球抜き装置は、球抜き操作によりシャッター板を自動的に球抜き孔を開放する位置に係止保持することができるものの、球抜きが終って球抜き状態を解除するには必ず解除操作を行なってシャッター板を球抜き孔を閉じる位置に戻さなければならなかった。このため、球受皿のパチンコ球の球抜きが終っても解除操作を忘れて球抜き状態のままで台を移動する遊技者が多くあり、次の遊技者に迷惑を及ぼしたり店員がいちいち解除操作しなければならないという問題点があった。
【０００４】
本発明は、従来の技術の有するこのような問題点に鑑みてなされたものであり、その目的とするところは、球受皿の皿部に貯留されるパチンコ球の重量により確実にシャッター板を球抜き位置に係止保持させることができると共に、皿部のパチンコ球が抜き取られるとシャッター板を球抜き解除位置に自動復帰させることができるようなパチンコ機における球受皿の球抜き装置を提供しようとするものである。
【０００５】
【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、パチンコ球が貯留される皿部の底壁に該皿部のパチンコ球を抜き取る球抜き孔と皿部のパチンコ球が落入する落入孔とを開設し、前記球抜き孔を開閉するシャッター板を前記皿部の下面に設けられる支持枠に付勢部材により前記球抜き孔を閉じる方向に付勢するように移動自在に装着し、前記落入孔の下方に臨ませて球重量により回動する揺動部材を前記支持枠に揺動自在に設け、前記揺動部材の一端に前記落入孔に落入したパチンコ球を支持する球支持部を形成すると共に他端に前記シャッター板を球抜き状態に保持する係止部をシャッター板の球抜き方向に向けて下傾する傾斜面に形成し、前記球抜き孔の開放時に前記落入孔に落入したパチンコ球の球重量により上向き回動した前記揺動部材の係止部がシャッター板を係止保持し、前記揺動部材が球重量から解放されるとシャッター板との係止が解除されて前記付勢部材の付勢力によりシャッター板が球抜き孔を閉じる位置に自動復帰するようにしたことを特徴とする。
【０００６】
また、パチンコ球が貯留される皿部の底壁に該皿部のパチンコ球を抜き取る球抜き孔と皿部のパチンコ球が落入する落入孔とを開設し、前記球抜き孔を開閉するシャッター板を前記皿部の下面に設けられる支持枠に付勢部材により前記球抜き孔を閉じる方向に付勢するように移動自在に装着し、前記落入孔に落入するパチンコ球の球重量により回動する揺動部材をシャッター板に揺動自在に設け、前記支持枠に前記シャッター板が球抜き孔を開放状態で係止する係合部を形成し、前記球抜き孔の開放時に球重量により下向き回動した揺動部材が前記係合部に係合してシャッター板を保持し、前記揺動部材が球重量から解放されると揺動部材の係止が解除されて前記付勢部材の付勢力によりシャッター板が球抜き孔を閉じる位置に自動復帰するようにしたことを特徴とする。
【０００７】
そして、前記球抜き孔を開設した皿部に少なくとも１個のパチンコ球が落入可能な落入孔を穿設し、該落入孔に落入するパチンコ球によって揺動部材を下向回動させるようにするのが好ましい。
【０００８】
また、前記シャッター板を球抜き孔を開放する位置に確実に係止保持させるため、該シャッター板に係合部を設け、該係合部に揺動部材を係合させるようにするのがよい。
【０００９】
さらに、皿部のパチンコ球を最後の１個まで球抜き可能とするため、前記揺動部材に、該揺動部材の上向回動時に落入孔を塞ぐ閉塞板を設けるのが好ましい。
【００１０】
また、前記シャッター板に揺動規制部を設け、該揺動規制部によってシャッター板が球抜き孔を開放する位置に移動するまでの間揺動部材の下向回動を阻止するようにするのが好ましく、これによって、揺動部材の無用な揺動を防ぐことが可能となる。
【００１１】
さらに、組立て作業の簡略化を図るために、前記シャッター板に操作部を有する揺動部材を揺動自在に枢着し、該揺動部材を皿部の落入孔に落入するパチンコ球により回動させるようにするのが好ましい。この場合シャッター板が支持される支持枠に係合部を設け、シャッター板に揺動自在に枢着された揺動部材を係合部に係合させることにより、シャッター板を球抜き孔を開放する位置に係止保持するようにすればよい。
【００１２】
また、前記シャッター板が支持される皿部の前面壁に係合部を設け、揺動部材の操作部を係合部に直接的に係合させ、又は操作部に被係合部を設けて係合部と被係合部とを係合させることによりシャッター板を球抜き孔を開放する位置に係止保持させるようにしてもよい。
【００１３】
前記した本発明の構成によれば、皿部に貯留されるパチンコ球の重量で回動する揺動部材により上向または下向回動した側が係止することによりシャッター板を球抜き孔を開放する位置に確実に保持することができると共に、揺動部材が皿部のパチンコ球の球重量から解放されるとシャッター板の係止保持が解除されるもので、これによって該シャッター板を球抜き孔を閉じる位置に自動復帰させることが可能となる。
【００１４】
なお、本発明のパチンコ機における球受皿の球抜き装置は、パチンコ機の前面枠の前面に設けられる打球供給用の上部球受皿または上部球受皿の余剰球を貯留する下部球受皿のいずれにも適用可能である。また、本発明の球抜き装置は、球抜き孔を開閉するシャッター板が左右方向又は前後方向に摺動自在に設けられているもの、或いは回動軸を支点に回動自在に設けられているもののいずれにも適用可能である。
【００１５】
【発明の実施の形態】
以下に本発明の第１実施の形態を図面と共に説明する。図１はパチンコ機の正面図、図２は下部球受皿の斜視図、図３は分解斜視図である。パチンコ機１の前面に開閉自在に前面枠２が設けられ、該前面枠２の後部に遊技盤３が位置する。４は遊技盤３の上方部分を覆うガラス枠、５は遊技盤３の下方部分を覆う前面板で、その前面に上部球受皿６が取付けられている。また、前面枠２の下方部前面には上部球受皿６の余剰球を貯留する下部球受皿７が装着されている。
【００１６】
下部球受皿７は、図２および図３に示すように皿部８と該皿部８の上部に被着させるカバー部材９とに二分割して形成されている。そして、皿部８の底壁１０のほぼ中央位置に多数のパチンコ球を同時に落下させる球抜き孔１１を開設すると共に、該球抜き孔１１とは別に球抜き孔１１の近傍にパチンコ球の直径とほぼ等しい大きさの落入孔１２を穿設している。また底壁１０は球抜き孔１１に向かって下傾しており、皿部８に貯留されたパチンコ球がすべて球抜き孔１１に向かうようにしている。１３は前記皿部８の底壁１０の球抜き孔１１を開閉するシャッター板であり、該シャッター板１３は皿部８の底壁１０下面と該底壁１０下面にビス着される支持枠１４との間に摺動自在に装着されており、支持枠１４に内装した付勢部材としてのスプリング１５の弾性により常時球抜き孔１１を閉じる方向に付勢されている。
【００１７】
前記シャッター板１３の前側縁には皿部８の外方に突出する操作部１６が突設されており、該操作部１６を手で操作することによってシャッター板１３を摺動し得るようにしている。またシャッター板１３の後側縁には、球抜き孔１１を閉じる位置（図４参照）で落入孔１２を閉塞する受片１７を一体に設けると共に、係合部１８が設けられている。該係合部１８の係合面は図６に示すように図上左下に向けて傾斜しており他方面は図上右下に向けた傾斜面としている。
【００１８】
また、前記支持枠１４には図３に示すように球抜き孔１１と相対する位置に、球抜き孔１１とほぼ同じ大きさの透孔１９が開設されると共に、支持片２１，２１に揺動部材２０が軸ピン２２により揺動自在に軸支されている。
【００１９】
前記揺動部材２０は、図６（ａ）に示すように常には重錘２３により下向回動（反時計回り方向）するように付勢されると共に、その一端に前記落入孔１２の下部に臨んで落入孔１２に落入したパチンコ球を支持する球支持部２４が屈曲形成されている。なお、落入孔１２に落入したパチンコ球の球心は、図６（ｂ）に示すようにシャッター板１３の受片１７より上方に位置しており、受片１７によって落入孔１２に落入したパチンコ球の下部を押して皿部８内に戻すようにしている。一方、球支持部２４が形成された反対側の端部には前記係合部１８に係合する係止部２５が形成されている。該係止部２５の係止面は、球抜き方向に向けて下傾する傾斜面として係合部１８との係合を解除し易いようになっている。なお重錘２３は、球支持部２４にパチンコ球１個より重い球重量がかかることによって揺動部材２０が揺動するようにその重さが選ばれる。
【００２０】
次に図面を参照して球受皿の球抜きの作用を説明する。通常シャッター板１３はスプリング１５の付勢により図４に示すように球抜き孔１１を閉塞しており、このとき落入孔１２は図６（ａ）に示すようにシャッター板１３の受片１７によって閉塞されている。この状態であり、かつ皿部８に多量のパチンコ球が貯留されているときに図６（ｂ）に示すように操作部１６に指を掛けてシャッター板１３を球抜き孔１１を開放する側へ摺動させると受片１７も同時に移動して落入孔１２が開放し、該落入孔１２に皿部８に貯留されているパチンコ球のうち１個が自然に落入して球支持部２４で支持される。そして、球支持部２４に支持されたパチンコ球に他のパチンコ球の球重量がかかることによって、図６（ｃ）に示すように揺動部材２０が重錘２３による付勢に抗して回動（時計回り方向）し、係止部２５が上動する。さらにシャッター板１３を球抜き孔１１を開放する側に摺動すると、揺動部材２０の係止部２５は一旦係合部１８の傾斜面により球支持部２４にかかる球重量に抗して下動する。
【００２１】
そしてシャッター板１３を球抜き孔１１をほぼ全開する位置に移動するとすぐに係合部１８が係止部２５を通過して揺動部材２０は球重量により元の位置に上動する。その状態で、操作部１６から手を離すとシャッター板１３がスプリング１５の付勢により球抜き孔１１を閉じる方向に復動しようとするが、図６（ｄ）に示すように揺動部材２０の上動した側の係止部２５が係合部１８と係合してその復動が阻止される。従って、操作部１６から手を離してもスプリング１５の付勢力より球支持部２４にかかる球重量の方が勝って、図５に示すようにシャッター板１３は球抜き孔１１をほぼ全開する状態に係止保持されることになる。そして、皿部８のパチンコ球は球抜き孔１１から透孔１９を落下して抜き取られる。
【００２２】
このようにして皿部８のパチンコ球が抜き取られて、球支持部２４にかかる球重量が減少すると、重錘２３の方が球支持部２４にかかる球重量より勝って図６（ｅ）に示すように揺動部材２０が上向回動（反時計回り方向）する。これに伴い係合部１８と係止部２５との係合が解除され、スプリング１５の付勢によりシャッター板１３が球抜き孔１１を閉じる位置に自動復帰することになる。このとき落入孔１２に落入したパチンコ球は、図６（ｅ）に示すようにシャッター板１３の受片１７によってパチンコ球の下方を押され、皿部８内に戻され球抜き孔１１から落下し図６（ｆ）に示すように球抜きが終了する。
【００２３】
また、落入孔１２に落入したパチンコ球が皿部８内に戻されるよりも先にシャッター板１３が球抜き孔１１を閉塞して、皿部８内にパチンコ球が残った場合には、再度シャッター板１３を開方向に移動すれば、球支持部２４に重錘２３に勝る球重量がかからないため、シャッター板１３はロックすることなく残ったパチンコ球を確実に抜き取ることができる。なお、前記落入孔１２を球抜き孔１１と別に設けたが、球抜き孔１１と連通状に設けるようにしてもよい。また、図７（ａ），（ｂ）に示すようにシャッター板１３を支軸３６を中心に回動させることにより球抜き孔１１を開閉する球抜き構造のもの、或いは図８（ａ），（ｂ）に示すようにシャッター板１３を前後方向へ摺動させることにより球抜き孔１１を開閉する球抜き構造の場合でも、シャッター板１３の形状や球抜き孔１１と落入孔１２との位置関係を変更することによって同じように適用可能である。
【００２４】
図９は前記揺動部材２０の球支持部２４に落入孔１２を閉塞する円盤状の閉塞板２６を一体に設けたものである。このように揺動部材２０に閉塞板２６を設けた場合、図１０（ａ）〜（ｄ）に示すように皿部８に貯留されたパチンコ球の重量が閉塞板２６にかかり揺動部材２０が回動（時計回り方向）し、揺動部材２０の上動した側の係止部２５が係合部１８と係合してシャッター板１３を球抜き孔１１を開放する位置で係止保持する。そして、パチンコ球が球抜き孔１１から抜き取られると、閉塞板２６にかかる球重量が減少し揺動部材２０が重錘２３によって回動（反時計回り方向）してシャッター板１３の係止状態を解除すると共に、閉塞板２６が落入孔１２を閉塞し、同時に落入孔１２に落入したパチンコ球を皿部８内に戻し球抜き孔１１から落下させる。このため、シャッター板１３の開放状態の解除と同時に揺動部材２０が揺動して落入孔１２に落入したパチンコ球を皿部８に戻すので、皿部８内にパチンコ球を残すことなく確実に球抜きを行うことができる。なお、揺動部材２０に閉塞板２６を設けた場合、シャッター板１３の受片１７は不要となる。
【００２５】
また、図１１は前記シャッター板１３の係合部１８を突起状として揺動部材２０の下向回動を規制する揺動規制部２７を兼用させるようにしたものであって、該揺動規制部２７の側面の係合部１８を軸ピン２２を中心とした円弧面として該係合部１８と揺動部材２０の係止部２５との係合を容易としている。このように、シャッター板１３に揺動規制部２７を設けた場合、図１２（ａ）〜（ｄ）に示すようにシャッター板１３が球抜き孔１１を開放する位置に移動するまでの間揺動規制部２７が揺動部材２０の上面に接触状に位置されているため、シャッター板１３により球抜き孔１１が閉じられているとき閉塞板２６に重錘２３に勝る球重量がかかったとしても揺動部材２０が下向回動するようなことがなく、またシャッター板１３が球抜き孔１１を開放する位置に移動するまで揺動部材２０が下向回動することがないため、揺動部材２０を球重量に抗して無用に揺動させるようなことがなくなり球抜き操作を至極円滑に行なうことができる。なお、前記揺動規制部２７を係合部１８と兼用するものとして説明したが係合部１８とは別々に設けるようにしてもよい。
【００２６】
以上、説明した第１実施の形態によれば、シャッター板１３を球抜き孔１１を開放する位置に摺動させると、皿部に貯留されるパチンコ球のうちの１個が落入孔１２に自然に落入し、このパチンコ球の球重量によってシャッター板１３と別に設けた揺動部材２０が回動して上向回動した側の係止部２５が係合部１８に係止して、該シャッター板１３を球抜き孔１１を開放する位置に保持させることができ、しかもパチンコ球が抜き取られて揺動部材２０にかかる球重量が減少することによって該揺動部材２０が回動しシャッター板１３の係止を解除して球抜き孔１１を閉じる位置に自動復帰させることができる。
【００２７】
次に、図１３ないし図１６を参照して、第２実施の形態に係る球受皿の球抜き装置について説明する。この第２実施の形態の球抜き装置が第１実施の形態の球抜き装置と異なるところは主としてシャッター板構造であるため、第１実施の形態と同じ構造のものには同一符号を付して示している。これについて説明すると、皿部８の底壁１０に開設された球抜き孔１１を開閉するシャッター板２８は、ほぼ中央位置に切欠開口２９を有し、該切欠開口２９に平板状の揺動部材３０を軸３１により揺動自在に枢着して構成されている。このシャッター板２８は、図１４に示すように常にはスプリング１５により付勢されて切欠開口２９の右側部分で球抜き孔１１を閉じるようにされており、このとき切欠開口２９の左側部分で落入孔１２を閉塞するようになっている。
【００２８】
一方、前記揺動部材３０の前部には皿部８の外方に突出する操作部３２が一体に設けられており、該操作部３２を手で操作することによって揺動部材３０がシャッター板２８と一体に摺動し得るようになっている。そして、図１５に示すようにシャッター板２８が球抜き孔１１を開放する位置に摺動されたとき落入孔１２の下方に位置して該落入孔１２に落入するパチンコ球を支持し得るようになっている。なお、揺動部材３０は図１６（ａ）に示すように落入孔１２がシャッター板２８で閉塞されているとき上向回動（反時計廻り方向）して皿部８の底壁１０下面で支持され、パチンコ球１個より重い球重量がかかると図１６（ｂ）に示すように下向回動（時計廻り方向）するように重心が設けられている。また、前記シャッター板２８が揺動自在に支持される皿部８の前面壁３３には係合部としての凹溝３４が設けられており、揺動部材３０の操作部３２上面にはシャッター板２８が球抜き孔１１を開放する位置まで摺動されたとき前記凹溝３４に係合する被係合部としての突起３５が突設されている。
【００２９】
このように構成された第２実施の形態の球抜き装置は、図１４及び図１６（ａ）に示すようにシャッター板２８によって球抜き孔１１と落入孔１２の両方が閉塞されているとき、皿部８に貯留されているパチンコ球を球抜きするべく操作部３２に指を掛けて揺動部材３０と一体にシャッター板２８を図１５に示す球抜き孔１１を開放する位置に摺動させると、揺動部材３０が落入孔１２の下方に移動することになる。このため、この球抜き状態で操作部３２から指を離すとシャッター板２８がスプリング１５の付勢により球抜き孔１１を閉じる方向に復動しようとするも落入孔１２に落入するパチンコ球の球重量で揺動部材３０が図１６（ｂ）に示すように軸３１を支点として回動（時計廻り方向）し、上動した側の操作部３２の突起３５が皿部８の凹溝３４に係合する。従って、シャッター板２８は図１５に示す球抜き孔１１を開放する位置に確実に係止保持されることになり、操作部３２から手を離した状態で皿部８のパチンコ球を球抜きすることができる。
【００３０】
一方、皿部８のパチンコ球が抜き取られて揺動部材３０にかかる球重量が減少すると該揺動部材３０は自重で軸３１を支点として上向回動し図１６（ａ）に示す位置に回動復帰する。このため、揺動部材３０の操作部３２が下動して皿部８の凹溝３４と操作部３２の突起３５との係合が解除され、スプリング１５の付勢によりシャッター板２８が図１４に示す球抜き孔１１を閉じる位置に自動復帰し同時に落入孔１２も閉塞されることになる。
【００３１】
この第２実施の形態の場合、例えばシャッター板２８を球抜き可能な半開状態に摺動させたとき、揺動部材３０が落入孔１２の下方に位置しないように球抜き孔１１、落入孔１２及び揺動部材３０の相互位置関係を設定することにより、皿部８に貯留されるパチンコ球を揺動部材３０に関係なく少量ずつ球抜きしながら遊技を行うことができ、遊技者にとって好都合となる。
【００３２】
なお、前記した第２実施の形態ではシャッター板２８を左右方向へ摺動可能に設けたものとして説明したが、図１７（ａ），（ｂ）に示すようにシャッター板２８を支軸３８を中心に回動させることにより球抜き孔１１を開閉する球抜き構造のもの、或いは図１８（ａ），（ｂ）に示すようにシャッター板２８を前後方向へ摺動させることにより球抜き孔１１を開閉する球抜き構造の場合でも、シャッター板２８の形状や揺動部材３０、球抜き孔１１、落入孔１２のそれぞれ相互位置関係を変更することによって同じように適用可能である。
【００３３】
また、前記した第２実施の形態では、皿部８の凹溝３４と揺動部材３０の操作部３２の突起３５とを係合させることによりシャッター板２８を球抜き孔１１を開放する位置に係止保持するものとして説明したが、図１９（ａ），（ｂ）に示すように凹溝３４を揺動部材３０の操作部３２の横幅とほぼ等しくすることにより操作部３２と凹溝３４とを直接に係合させるようにしてもよい。さらに、図２０（ａ），（ｂ）に示すように皿部８の下面にビス着される支持枠１４の上面に係合部としての係合突起３７を設け、図２０（ｂ）に示すようにシャッター板２８が球抜き孔１１を開放する位置で揺動部材３０の下向回動した側面を被係合部として係合突起３７に係合させるようにしてもよい。
【００３４】
このように、この第２実施の形態の場合、皿部８に貯留されるパチンコ球の球重量により揺動してシャッター板２８を球抜き孔１１を開放する位置に係止保持し、球重量から解放されるとシャッター板２８を球抜き孔１１を閉じる位置に自動復帰させる作用を果たす揺動部材３０をシャッター板２８に軸支して該シャッター板２８と一体構造としたものであるから、第１実施の形態のようにシャッター板１３と揺動部材２０とを別々に組付ける必要がなくなり、球抜き構造を簡略化することができると共に、作業性の向上並びにコスト削減を図ることができる。
【００３５】
【発明の効果】
以上説明したところから明らかなように、本発明のパチンコ機における球受皿の球抜き装置によれば、球受皿の皿部に貯留されるパチンコ球の球重量により回動する揺動部材を回動自在に設け、該揺動部材の上動または下動した側が係止することによりシャッター板を球抜き孔を開放する位置に保持すると共に、その球重量から解放されるとシャッター板を球抜き孔を閉じる位置に自動復帰させるようにしたものであるから、球受皿の球抜き操作を至極容易に行うことができると共に、球抜き状態のままで放置されるようなことがなくなり、従来のように他の遊技者に迷惑を及ぼしたり店員の手を煩わせるような事態を完全に解消することができる。

In addition, a lower sphere tray 7 for storing excess spheres of the upper sphere tray 6 is mounted on the lower front surface of the front frame 2.
[0016]
As shown in FIGS. 2 and 3, the lower ball tray 7 is divided into two parts, a dish part 8 and a cover member 9 to be attached to the upper part of the dish part 8. A ball hole 11 for simultaneously dropping a large number of pachinko balls at the substantially central position of the bottom wall 10 of the dish portion 8 is opened, and the diameter of the pachinko ball is formed in the vicinity of the ball hole 11 separately from the ball holes 11. The drop-in hole 12 having a size almost equal to that of the first hole is formed. The bottom wall 10 is inclined downward toward the ball hole 11 so that all the pachinko balls stored in the dish portion 8 are directed toward the ball hole 11. Reference numeral 13 denotes a shutter plate that opens and closes a ball punching hole 11 in the bottom wall 10 of the plate portion 8, and the shutter plate 13 is screwed to the bottom wall 10 bottom surface of the plate portion 8 and the bottom wall 10 bottom surface. And is urged in a direction to always close the ball removal hole 11 by the elasticity of a spring 15 as an urging member built in the support frame 14.
[0017]
An operation portion 16 that protrudes outward from the dish portion 8 is provided on the front edge of the shutter plate 13 so that the shutter plate 13 can be slid by operating the operation portion 16 by hand. Yes. The rear edge of the shutter plate 13 is integrally provided with a receiving piece 17 that closes the drop-in hole 12 at a position (see FIG. 4) where the ball hole 11 is closed, and an engaging portion 18 is provided. As shown in FIG. 6, the engaging surface of the engaging portion 18 is inclined toward the lower left in the drawing, and the other surface is an inclined surface directed to the lower right in the drawing.
[0018]
Further, as shown in FIG. 3, the support frame 14 is provided with a through hole 19 having a size substantially the same as that of the ball punch hole 11 at a position facing the ball punch hole 11, and the support pieces 21, 21 are rocked. The moving member 20 is pivotally supported by the shaft pin 22 so as to be swingable.
[0019]
As shown in FIG. 6A, the swinging member 20 is always urged to rotate downward (counterclockwise) by the weight 23, and at one end of the drop-in hole 12 is provided. A sphere support portion 24 that supports the pachinko ball that has fallen into the drop hole 12 facing the lower portion is bent. The center of the pachinko ball that has fallen into the drop-in hole 12 is positioned above the receiving piece 17 of the shutter plate 13 as shown in FIG. The lower part of the fallen pachinko ball is pushed back into the dish part 8. On the other hand, an engaging portion 25 that engages with the engaging portion 18 is formed at the opposite end where the ball support portion 24 is formed. The locking surface of the locking portion 25 is an inclined surface that inclines downward in the ball pulling direction so that the engagement with the engaging portion 18 can be easily released. The weight of the weight 23 is selected so that the rocking member 20 swings when a ball weight heavier than one pachinko ball is applied to the ball support 24.
[0020]
Next, the action of removing the balls from the ball tray will be described with reference to the drawings. Normally, the shutter plate 13 closes the ball hole 11 as shown in FIG. 4 by the bias of the spring 15. At this time, the drop-in hole 12 receives the receiving piece 17 of the shutter plate 13 as shown in FIG. It is blocked by In this state, when a large amount of pachinko balls are stored in the dish portion 8, as shown in FIG. 6B, a finger is put on the operation portion 16 to open the shutter hole 13 and the ball hole 11. , The receiving piece 17 also moves simultaneously, and the drop hole 12 is opened, and one of the pachinko balls stored in the dish portion 8 naturally drops into the drop hole 12 to support the ball. Supported by part 24. Then, when the pachinko sphere supported by the sphere support 24 is subjected to the weight of the other pachinko sphere, the swinging member 20 rotates against the urging force by the weight 23 as shown in FIG. It moves (clockwise direction), and the locking part 25 moves up. When the shutter plate 13 is further slid to the side where the ball hole 11 is opened, the locking portion 25 of the swinging member 20 is lowered against the ball weight applied to the ball support portion 24 by the inclined surface of the engagement portion 18 once. Move.
[0021]
As soon as the shutter plate 13 is moved to a position where the ball punching hole 11 is almost fully opened, the engaging portion 18 passes through the locking portion 25 and the swinging member 20 is moved upward to the original position by the weight of the ball. In this state, when the hand is released from the operation unit 16, the shutter plate 13 tries to move backward in the direction to close the ball extraction hole 11 by the bias of the spring 15, but as shown in FIG. The locking portion 25 on the side moved upward is engaged with the engaging portion 18 and its return movement is prevented. Therefore, even when the hand is released from the operation portion 16, the weight of the ball applied to the ball support portion 24 is greater than the urging force of the spring 15, and the shutter plate 13 is in a state where the ball hole 11 is almost fully opened as shown in FIG. It will be latched and held. Then, the pachinko balls in the dish portion 8 are extracted by dropping through the through holes 19 from the ball extraction holes 11.
[0022]
When the pachinko balls of the plate portion 8 are extracted in this way and the ball weight applied to the ball support portion 24 decreases, the weight 23 wins over the ball weight applied to the ball support portion 24 and is shown in FIG. As shown, the swing member 20 rotates upward (counterclockwise direction). As a result, the engagement between the engaging portion 18 and the locking portion 25 is released, and the shutter plate 13 automatically returns to the position where the ball hole 11 is closed by the urging of the spring 15. At this time, the pachinko ball dropped into the drop hole 12 is pushed below the pachinko ball by the receiving piece 17 of the shutter plate 13 as shown in FIG. And the ball removal is completed as shown in FIG.
[0023]
In addition, when the pachinko ball that has fallen into the drop-in hole 12 is returned to the dish portion 8, the shutter plate 13 closes the ball removal hole 11 and the pachinko ball remains in the dish portion 8. If the shutter plate 13 is moved again in the opening direction, the ball support portion 24 does not have a sphere weight that exceeds the weight 23, so that the shutter plate 13 can reliably extract the remaining pachinko balls without locking. Although the drop-in hole 12 is provided separately from the ball hole 11, it may be provided in communication with the ball hole 11. Further, as shown in FIGS. 7A and 7B, the shutter plate 13 rotates around the support shaft 36 to open and close the ball release hole 11, or FIG. As shown in (b), even in the case of a ball removal structure that opens and closes the ball release hole 11 by sliding the shutter plate 13 in the front-rear direction, the shape of the shutter plate 13 and the shape of the ball release hole 11 and the drop-in hole 12 The same can be applied by changing the positional relationship.
[0024]
In FIG. 9, a disc-shaped closing plate 26 for closing the drop-in hole 12 is integrally provided on the ball support portion 24 of the swing member 20. When the closing plate 26 is provided on the swing member 20 as described above, the weight of the pachinko balls stored in the plate portion 8 is applied to the close plate 26 as shown in FIGS. Is rotated (clockwise), and the locking portion 25 on the side where the swinging member 20 is moved upward is engaged with the engaging portion 18 so that the shutter plate 13 is locked and held at the position where the ball hole 11 is opened. To do. When the pachinko ball is extracted from the ball extraction hole 11, the weight of the ball applied to the closing plate 26 is reduced, and the swinging member 20 is rotated by the weight 23 (counterclockwise direction) so that the shutter plate 13 is locked. In addition, the closing plate 26 closes the drop-in hole 12, and at the same time, the pachinko balls dropped into the drop-in hole 12 are returned to the dish portion 8 and dropped from the ball removal hole 11. For this reason, the swinging member 20 swings simultaneously with the release of the shutter plate 13 to return the pachinko ball that has fallen into the drop-in hole 12 to the dish part 8, leaving the pachinko ball in the dish part 8. The ball can be removed without fail. When the closing plate 26 is provided on the swing member 20, the receiving piece 17 of the shutter plate 13 is not necessary.
[0025]
Further, FIG. 11 shows a state in which the engaging portion 18 of the shutter plate 13 is formed in a protruding shape so that the swing restricting portion 27 for restricting the downward rotation of the swing member 20 is also used. The engagement portion 18 on the side surface of the portion 27 is formed as an arc surface centered on the shaft pin 22 to facilitate engagement between the engagement portion 18 and the locking portion 25 of the swing member 20. Thus, when the rocking | fluctuation control part 27 is provided in the shutter board | plate 13, as shown in FIG. 12 (a)-(d), it shakes until the shutter board | plate 13 moves to the position which open | releases the ball hole 11. Since the movement restricting portion 27 is positioned in contact with the upper surface of the swinging member 20, it is assumed that when the ball release hole 11 is closed by the shutter plate 13, the ball weight exceeding the weight 23 is applied to the closing plate 26. However, the swinging member 20 does not rotate downward, and the swinging member 20 does not rotate downward until the shutter plate 13 moves to the position where the ball release hole 11 is opened. The moving member 20 is not unnecessarily rocked against the weight of the ball, and the ball removing operation can be performed extremely smoothly. In addition, although the said rocking | fluctuation control part 27 was demonstrated as what also uses the engaging part 18, you may make it provide separately from the engaging part 18. FIG.
[0026]
As described above, according to the first embodiment described above, when the shutter plate 13 is slid to the position where the ball release hole 11 is opened, one of the pachinko balls stored in the dish portion becomes the drop hole 12. The rocking member 20 provided separately from the shutter plate 13 is rotated by the ball weight of the pachinko ball, and the locking portion 25 on the side rotated upward is locked to the engaging portion 18. The shutter plate 13 can be held at a position where the ball punching hole 11 is opened, and the swinging member 20 is rotated by reducing the weight of the swinging member 20 by extracting the pachinko ball. The shutter plate 13 can be unlocked and automatically returned to the position where the ball hole 11 is closed.
[0027]
Next, with reference to FIG. 13 thru | or FIG. 16, the ball | bowl removal apparatus of the ball tray which concerns on 2nd Embodiment is demonstrated. Since the ball punching device of the second embodiment is different from the ball punching device of the first embodiment mainly in the shutter plate structure, the same structure as that of the first embodiment is denoted by the same reference numeral. Show. Explaining this, the shutter plate 28 that opens and closes the ball hole 11 formed in the bottom wall 10 of the plate portion 8 has a notch opening 29 at a substantially central position, and a flat plate-like rocking member is provided in the notch opening 29. 30 is pivotally attached to a shaft 31 so as to be swingable. As shown in FIG. 14, the shutter plate 28 is always urged by the spring 15 to close the ball hole 11 at the right side portion of the notch opening 29. At this time, the shutter plate 28 drops at the left side portion of the notch opening 29. The entrance hole 12 is closed.
[0028]
On the other hand, an operating portion 32 that protrudes outward from the dish portion 8 is integrally provided at the front portion of the swinging member 30, and the swinging member 30 is operated by hand by operating the operating portion 32. 28 can slide integrally. Then, as shown in FIG. 15, when the shutter plate 28 is slid to the position where the ball hole 11 is opened, the pachinko ball positioned below the hole 12 and falling into the hole 12 is supported. To get. The swing member 30 rotates upward (counterclockwise direction) when the drop-in hole 12 is closed by the shutter plate 28 as shown in FIG. The center of gravity is provided so as to rotate downward (clockwise) as shown in FIG. 16 (b) when a ball weight heavier than one pachinko ball is applied. Further, a concave groove 34 as an engaging portion is provided in the front wall 33 of the dish portion 8 on which the shutter plate 28 is swingably supported, and a shutter plate is provided on the upper surface of the operation portion 32 of the swing member 30. A projection 35 is provided as an engaged portion that engages with the groove 34 when 28 is slid to the position where the ball hole 11 is opened.
[0029]
In the ball removing device according to the second embodiment configured as described above, when both the ball removing hole 11 and the falling hole 12 are closed by the shutter plate 28 as shown in FIGS. 14 and 16A. In order to remove the pachinko balls stored in the plate part 8, the operation part 32 is put on a finger, and the shutter plate 28 is slid to the position where the ball hole 11 shown in FIG. As a result, the swing member 30 moves below the drop-in hole 12. For this reason, when the finger is released from the operation unit 32 in this ball-extracted state, the shutter plate 28 tries to move backward in the direction to close the ball-extract hole 11 by the urging of the spring 15, but the pachinko ball enters the entrance hole 12. As shown in FIG. 16B, the swinging member 30 rotates about the shaft 31 (clockwise direction) as shown in FIG. 16B, and the protrusion 35 of the operating portion 32 on the side moved upward is the concave groove of the plate portion 8. 34 is engaged. Accordingly, the shutter plate 28 is securely locked and held at a position where the ball punching hole 11 shown in FIG. 15 is opened, and the pachinko ball on the plate portion 8 is removed in a state where the hand is released from the operation unit 32. be able to.
