Description

【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に球抜き孔を開設し、該球受皿の下面に設けた開閉板を摺動また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、特に開閉板を球抜き孔を開放する位置に停止保持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、開閉板を係止部材によって球抜き位置に係止し、押圧部材の押圧によってその係止を解除するようにした球受皿の球抜き装置は知られている（例えば特公平３−５３９５４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、多くの部品を必要として構造が複雑で、組立に手間が掛かってコスト高になるという問題があった。また、皿部にパチンコ球がない状態でも開閉板を摺動させると球抜き位置に停止保持されてしまい、開閉板の停止状態を解除するためには必ず停止解除操作をし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わっても解除操作をするのを忘れて、球受皿が球抜き状態に置かれたままとなり、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をしなければならないという問題があった。
【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、簡単な構造で確実に開閉板を球抜き位置に停止保持させることができると共に、球受皿のパチンコ球が抜き取られると自動的に停止状態を解除して、開閉板を球抜き解除位置に復帰させることができる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と共に前記落入孔に落入したパチンコ球を支持する開閉板を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前記皿部の下面に設けられる支持枠に移動自在に装着し、前記支持枠に前記開閉板が前記球抜き孔を開放した位置で係止する係合部を段差を介して形成し、前記開閉板は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下動して前記係合部に係合する係止部を形成し、皿部のパチンコ球が球抜き孔から流出し球重量から解放されると前記係合部との係合が解除され球抜き孔を閉じる位置に自動復帰させるようにした。
【０００６】
そして、前記開閉板に確実にパチンコ球の重量を受けるために、球抜き孔を開設した皿部にパチンコ球が落入する落入孔を穿設し、該落入孔に落入するパチンコ球により、開閉板を球抜き孔を開放する位置に係止保持するのが好ましい。
【０００７】
また、前記開閉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、該開閉板に係止部を設け、前記支持枠に球抜き孔を開放する位置で前記係止部が係止する係合部を設けるようにするのがよい。
【０００８】
さらに、前記落入孔にパチンコ球が残らないように落入孔を球抜き孔と連通して設けるのがよい。
【０００９】
また、前記球抜き孔を複数設けて遊技中の少量の球抜きをやり易くし、かつ球抜きを速く行えるようにするのがよい。
【００１０】
また、開閉板を段階的に係止して皿部にパチンコ球が残らないように、前記球抜き孔の開閉度合を違えて係合する係合部を複数設けるのが好ましい。
【００１１】
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に、前記落入孔を球抜き孔の閉塞側に設けるのが好ましい。
【００１２】
また、皿部のパチンコ球が早く抜き取られるように、前記開閉板の上面を球抜き孔の閉鎖時に球抜き孔に向う傾斜面とするのが好ましい。
【００１３】
前記係合部は、段差を持って形成し開閉板が下動または傾動することにより係合するようにしてもよい。
【００１４】
前記係合部は凹孔とし、開閉板が下動または傾動することにより係合するようにしてもよい。
【００１５】
前記落入孔の形状または大きさを変えることにより、開閉板の係止解除のタイミングをかえることができる。
【００１６】
前記した本発明によれば、皿部にパチンコ球が貯留されている状態で開閉板を付勢部材の付勢に抗して球抜き孔をほぼ全開する位置に移動させると、落入孔に位置するパチンコ球の球重量が開閉板にかかることによって、開閉板から手を離しても皿部のパチンコ球を球抜き孔から球抜きすることができ、球抜き孔から球が抜けて、開閉板が皿部のパチンコ球の球重量から解放されて開閉板の停止状態が自動的に解除されるもので、これによって開閉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。
【００１７】
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。
【００１８】
また、本発明の球抜き装置は、球抜き孔を開閉する開閉板が前後方向または左右方向に摺動自在に設けられたもの、あるいは回動自在に設けられたものにも適用可能である。
【００１９】
【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は下部球受皿の分解斜視図である。パチンコ機１の前面に額縁状の前面枠２が開閉自在に設けられ、該前面枠２にガラス扉枠３と前面板４が装着される。前記ガラス扉枠３の後側には遊技盤５が設けられ、前記前面板４の前面に上部球受皿６が取付けられる。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。
【００２０】
下部球受皿７は、図２および図３に示すように多量のパチンコ球を貯留する皿部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のほぼ中央位置に複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とは別に球抜き孔の近傍に複数のパチンコ球が落入する落入孔１２を穿設している。また底壁１０は球抜き孔１１に向って下傾しており、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を開閉する開閉板であり、該開閉板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との間に移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の弾性により常に球抜き孔１１を閉じる方向に付勢されている。
【００２１】
前記開閉板１３の前側縁には支持枠１４の切欠凹部１４ａから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開閉板１３を移動し得るようにしている。また開閉板１３は、球抜き孔１１を閉じる閉塞板部１７と球抜き孔１１の閉塞時に落入孔１２を閉塞する球受け板部１８を有しており、右端縁に係止部１９を設けている。該係止部１９の下端縁はアール面として係合を解除しやすくしている。
【００２２】
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２０が開設されている。また、球抜き孔１１の閉塞時に開閉板１３を支持する支持部２１と開閉板１３が球抜き孔１１を開放した位置で前記係止部１９が係合する係合部２２が段差２３を介して形成されている。段差２３は開閉板１３が滑らかに閉塞するようにテーパー面としている。
【００２３】
次に図面を参照して球受皿の球抜きの作用を説明する。通常開閉板１３は図４に示すようにスプリング１５の付勢により球抜き孔１１を閉塞板部１７によって閉塞し、落入孔１２を球受板部１８によって閉塞している。この状態でありかつ図６（ａ）に示すように皿部８に多量のパチンコ球が貯留されているときに、操作部１６に指を掛けて開閉板１３をスプリング１５の付勢に抗して球抜き孔１１を開放する側へ移動させると、開閉板１３が支持部２１の支持から外れ、落入孔１２に位置するパチンコ球にかかる球重量によって段差２３のテーパー面に沿って下動しながら球抜き孔１１を開放し、皿部８のパチンコ球は底壁１０の傾斜によって球抜き孔１１から落下し始める。そして図６（ｂ）に示すように、開閉板１３を球抜き孔１１を開放する位置まで移動させると、落入孔１２に位置するパチンコ球にかかる球重量によって、開閉板１３が下動し係止部１９が係合部２２に係合する。従って、操作部１６から手を離してもスプリング１５の付勢力より開閉板１３にかかる球重量の方が勝って、図５に示すように開閉板１３は球抜き孔１１を開放する状態に停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２０を落下して抜き取られる。
【００２４】
このようにして皿部８のパチンコ球が抜き取られて、落入孔１２から開閉板１３にかかる球重量が減少すると、図６（ｃ）に示すように、スプリング１５の付勢力の方が開閉板１３にかかる球重量より勝って係止部１９と係合部２２との係合が解除され、開閉板１３が復動し球抜き孔１１を閉じることになる。このとき落入孔１２のパチンコ球は、開閉板１３が戻る勢いで跳ね上げられ皿部８に戻される。
【００２５】
以上、説明した第１実施の形態によれば、開閉板１３を球抜き孔１１を開放する側へ移動させると、落入孔１２に位置するパチンコ球にかかる球重量によって該開閉板１３を下動させ、係止部１９を係合部２２に係合して球抜き位置に停止保持させることができる。しかもパチンコ球が抜き取られて開閉板１３にかかる球重量が減少することによって自動的に開閉板１３の係合を解除するため、開閉板１３の無用な開放状態を防ぐことができる。また、球抜きを途中で中止したい場合には、操作部１６を開閉板１３にかかる球重量に抗して少し上動すれば係合が外れ、スプリング１５の付勢により球抜き孔１１を閉塞することができ、皿部８から少しのパチンコ球を抜くことも簡単に行うことができる。
【００２６】
また、どちらか一方の係止部１９または係合部２２が摩耗して係合不能となったとしても、球抜き孔１１の開閉動作には何の支障もなく皿部８のパチンコ球を球抜きすることができる。なお、係合部２２は図７に示すような凹孔としてもよく、開閉板１３下面に突設した係止部１９を係合させるようにすればよい。
【００２７】
次に、図８ないし図１０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。なお、前記第１実施の形態と同じ構成要素には同一符号を付して説明する。この実施の形態は、図８および図９に示すように、落入孔１２は多数のパチンコ球を同時に落入する大きさであり、球抜き孔１１とほぼ同じ径として球抜き孔１１と連通させている。また、開閉板１３の後側右側を係止部１９とし、支持枠１４の後方に開閉板１３が球抜き孔１１を開放した位置で前記係止部１９が係合する係合部２２を突設し、図１０に示すように開閉板１３を球抜き孔１１を開放した際に開閉板１３の後方が下動して、係止部１９が係合部２２に係合して開閉板１３を球抜き孔１１を開放した位置に保持するようにしている。
【００２８】
このように、落下孔１２を球抜き孔１１と連通して設けることにより、落下孔１２にパチンコ球が残ることがなく、例え球抜き孔１１から落下するよりも先に開閉板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、再度開閉板１３を開方向に移動すれば、開閉板１３にスプリング１５の付勢力に勝る球重量がかからないため、開閉板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、本実施の形態では係止部１９を開閉板１３の後側右端に設けるように説明したが、係止部１９を例えば支持枠１４の外方に突出した操作部１６を利用してもよく、支持枠１４の切欠凹部１４ａに係合部２２を切欠して設けるようにすればよい。
【００２９】
次に、図１１を参照して第３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。この実施の形態は、落下孔１２を球抜き孔１１と前後方向に連通して設けると共に、別に球抜き孔１１ａを設けている。また、支持枠１４には該球抜き孔１１ａに対応位置して透孔２０ａが設けられ、開閉板１３が球抜き孔１１，１１ａを開放する位置で開閉板１３の下面に設けられたＴ字状の係止部１９に係合する係合部２２が設けられている。該係合部２２は円弧形状をしており、前記係止部１９とは常に一点で係合するため、成形時に開閉板１３にがたつきがあっても調整が容易にできる。
【００３０】
次に図面を参照して球抜きの作用を説明する。通常図１１（ａ）に示すように開閉板１３は支持部２１に支持され、スプリング１５の付勢により球抜き孔１１，１１ａおよび落入孔１２を閉塞している。そして、開閉板１３を図１１（ｂ）に示すようにスプリング１５の付勢に抗して摺動すると球抜き孔１１ａが開放し、透孔２０ａからパチンコ球が落下する。このとき開閉板１３は、支持部２１で支持され球抜き孔１１および落入孔１２は閉塞した状態にある。さらに開閉板１３をスプリング１５の付勢に抗して摺動すると図１１（ｃ）に示すように開閉板１３は支持部２１から外れ、落入孔１２に位置するパチンコ球の球重量により段差２３のテーパー面を下動して係止部１９が係合部２２に係合し、球抜き孔１１，１１ａを開放した位置に停止保持され、球抜き孔１１，１１ａからパチンコ球が落下し、透孔２０，２０ａから球抜きされる。
【００３１】
このようにして皿部８のパチンコ球が抜き取られて、落入孔１２の開閉板１３にかかる球重量が減少すると、係止部１９と係合部２２との係合が解除され、図１１（ａ）に示す位置に開閉板１３が復動し球抜き孔１１，１１ａを閉じることになる。このとき落入孔１２に位置するパチンコ球は、連通する球抜き孔１１から落下して抜き取られる。この実施の形態では遊技中にタバコ等の景品交換をする際の少量のパチンコ球の抜き取り時に図１１（ｂ）に示す状態で抜けば、開閉板１３は下動することなくロックせず、遊技者に余分な手間をかけさせることなくパチンコ球を抜くことができる。またパチンコ球を複数の球抜き孔１１，１１ａから抜き取るので、当然のことながら皿部８のパチンコ球を速く球抜きをすることができる。
【００３２】
図１２ないし図１５は第４実施の形態を示すもので、前記実施の形態と異なるところは主に開閉板１３の係止構造であるため、同じ構成要素には同一符号を付して説明する。この実施の形態は、開閉板１３に複数の第１係止部１９ａ，第２係止部１９ｂを設けている。該第１係止部１９ａは開閉板１３の左端縁下面に垂下して形成され、第２係止部１９ｂは前記第１実施の形態と同様に開閉板１３の右端縁に形成される。そして第１係止部１９ａ，第２係止部１９ｂの下端縁はアール面として係合を解除しやすくしている。また開閉板１３の上面は、球抜き孔１１の閉鎖時に球抜き孔１１に向う傾斜面となるようになっている。
【００３３】
また、支持枠１４には、開閉板１３にかかる球重量により、前記第１係止部１９ａ，第２係止部１９ｂが球抜き孔１１の開放状態を違えて段階的に係止する第１係合部２２ａ，第２係合部２２ｂを位置をずらして段差をもって形成されている。
【００３４】
次に図面を参照して第４実施の形態の球受皿の球抜きの作用を説明する。通常開閉板１３は図１３に示すようにスプリング１５の付勢により球抜き孔１１を閉塞板部１７によって閉塞し、落入孔１２を球受板部１８によって閉塞している。この状態でありかつ図１５（ａ）に示すように皿部８に多量のパチンコ球が貯留されているときに、操作部１６に指を掛けて開閉板１３をスプリング１５の付勢に抗して球抜き孔１１を開放する側へ移動させると、皿部８のパチンコ球は傾斜状になった開閉板１３の上面を転がりながら球抜き孔１１から落下し始める。そして図１５（ｂ）に示すように、開閉板１３を球抜き孔１１をほぼ全開する位置に移動すると、落入孔１２に位置するパチンコ球の重量が開閉板１３にかかることによって開閉板１３が下動し、第１係止部１９ａが第１係合部２２ａに係合する。従って、操作部１６から手を離してもスプリング１５の付勢力より開閉板１３にかかる球重量の方が勝って、第１係止部１９ａと第１係合部２２ａの係合が保持され、開閉板１３は図１４に示すように球抜き孔１１をほぼ全開する状態で停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２０を落下して抜き取られる。
【００３５】
こうして皿部８のパチンコ球が抜き取られて、開閉板１３にかかる球重量が減少すると、開閉板１３にかかる球重量よりスプリング１５の付勢力の方が勝って、第１係止部１９ａと第１係合部２２ａとの係合が解除され、開閉板１３が復動するが、この復動により図１５（ｃ）に示すように、球受板部１８上に載るパチンコ球が増えることにより、開閉板１３にかかる球重量がスプリング１５の付勢力に勝って第２係止部１９ｂが第２係合部２２ｂに係合し、再度球抜き孔１１を開放する位置に開閉板１３を停止保持する。そしてさらに皿部８のパチンコ球が抜き取られて、開閉板１３にかかる球重量が減少すると、開閉板１３にかかる球重量よりスプリング１５の付勢力の方が勝って、第２係止部１９ｂと第２係合部２２ｂとの係合を解除し、図１５（ｄ）に示すように開閉板１３が球抜き孔１１を閉じる位置に復動する。
【００３６】
このように、開閉板１３を段階的に係合するようにすることで、皿部８にパチンコ球が残り難くすることができる。また、どちらか一方の係止部１９ａ，１９ｂまたは係合部２２ａ，２２ｂが摩耗して係合不能となっても、もう一方が係合することで開閉板１３を球抜き孔１１の開放位置に保持することができる。
【００３７】
図１６および図１７は、第５実施の形態を示すもので、落入孔１２を開閉板１３が球抜き孔１１を閉塞する方向に連通して設け、球受け板部１８に球抜き孔１１とほぼ同じ大きさの開孔２４が設けられている。そして係止部１９が開閉板１３の閉塞側の端縁下方に垂下して設けられており、支持枠１４の透孔２０の開口端に係合部２２が設けられている。なお透孔２０は、ほぼ球抜き孔１１と落入孔１２と同じ大きさに形成されている。
【００３８】
次に図面を参照してこの第５実施の形態の球受皿の球抜きの作用を説明する。通常開閉板１３は図１６に示すようにスプリング１５の付勢により球抜き孔１１を閉塞板部１７によって閉塞し、落入孔１２を球受板部１８によって閉塞している。この状態でありかつ図１７（ａ）に示すように皿部８に多量のパチンコ球が貯留されているときに操作部１６に指を掛けてスプリング１５の付勢に抗して開閉板１３を球抜き孔１１を開放する側へ移動させると、皿部８のパチンコ球は傾斜状の開閉板１３の上面を転がりながら球抜き孔１１から落下し始める。そして、図１７（ｂ）に示すように開閉板１３を球抜き孔１１を開放する位置に移動すると落入孔１２に位置するパチンコ球の重量によって開閉板１３が下動し、係止部１９が係合部２２に係合して、開閉板１３を球抜き孔１１を開放する状態に停止保持する。そして、皿部８のパチンコ球は球抜き孔１１から開孔２４を介して透孔２０を落下して抜き取られる。
【００３９】
こうして皿部８のパチンコ球が抜き取られると、開閉板１３にかかる球重量が減少して、スプリング１５の付勢力の方が勝って図１７（ｃ）に示すように、係止部１９と係合部２２との係合が解除され、開閉板１３が復動して球抜き孔１１を閉じることになる。この時落入孔１２に位置して球受け板部１８に受けられていたパチンコ球は、開閉板１３の移動と共に落入孔１２の開口縁に押されて開孔２４を介して透孔２０から落下して皿部８にパチンコ球を残すことなく確実に抜き取られる。
【００４０】
以上説明したが、落入孔１２の形状や大きさを変えることにより開閉板１３にかかる球重量を調節することができ、開閉板１３の係合解除のタイミングを調整することができる。また、スプリング１５の付勢力を調節することによっても調整することができる。
【００４１】
【発明の効果】
以上説明したことから明らかなように、本発明における球受皿の球抜き装置は、開閉板にかかるパチンコ球の球重量を利用して開閉板を球抜き位置に停止保持させると共に、球受皿のパチンコ球が抜けることにより開閉板にかかるパチンコ球の球重量が減少して開閉板の停止状態を自動的に解除するようにしたものであるから、わざわざ停止解除操作をする必要がなくなる。従って、いたずらや不注意によって球受皿を球抜き状態に放置されるような事態を確実に防止することができる。
【００４２】
さらに、従来の部品点数で構成することができて、余分な可動部品が不要であるから構造が簡単であり、万一何らかのトラブルにより開閉板を球抜き孔の開放状態が保持できなくなっても、何の支障もなく球抜きすることが可能である。

2. Description of the Related Art Conventionally, there is known a ball removing device for a ball receiving tray in which an opening / closing plate is locked at a ball removal position by a locking member, and the locking is released by pressing a pressing member (for example, Japanese Patent Publication No. 3-53954). See the official gazette).
[0003]
[Problems to be solved by the invention]
Conventional ball receiving devices for ball receiving trays have a problem that a large number of parts are required and the structure is complicated, and it takes time and labor to assemble. In addition, even if there is no pachinko ball in the pan, sliding the open / close plate stops the ball at the ball removal position, so a stop release operation must be performed to release the open / close plate stop state. . For this reason, forgetting to perform the release operation even after the pachinko ball is removed from the ball tray, the ball tray remains in the ball-free state, causing inconvenience to the next player and the store clerk releasing each time There was a problem that had to be operated.
[0004]
The present invention has been made in view of such problems of the prior art, and an object of the present invention is to make it possible to stop and hold the opening / closing plate at the ball removal position with a simple structure. An object of the present invention is to provide a ball draining device for a ball tray in a pachinko machine that automatically releases the stop state when the pachinko ball of the ball tray is pulled out and can return the open / close plate to the ball release release position. .
[0005]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention provides a hole for extracting a pachinko ball in the dish part and a recess hole in which the pachinko ball in the dish part falls into the bottom wall of the dish part in which the pachinko ball is stored. An opening and closing plate that opens and closes the ball hole and supports the pachinko ball that has fallen into the drop hole is biased to the bottom surface of the plate portion by a biasing member in a direction to close the ball hole. An engagement portion that is movably attached to a support frame that is provided and that is engaged with the support frame at a position where the opening / closing plate opens the ball hole is formed through a step, and the opening / closing plate is formed by the ball opening hole. The pachinko ball is moved downward by the ball weight of the pachinko ball that has fallen into the drop-in hole when it is opened to form a locking portion that engages with the engagement portion, and the pachinko ball in the dish portion flows out of the ball removal hole and the ball weight is automatically returned to engagement closes the release by ball vent hole positions of the engaging portion to be released from Was Unishi.
[0006]
Then, in order to reliably receive the weight of the pachinko ball on the opening and closing plate, a pachinko ball into which the pachinko ball is dropped is formed in the dish part in which the ball opening hole is opened, and the pachinko ball is dropped into the drop hole. Therefore, it is preferable that the opening / closing plate is locked and held at a position where the ball hole is opened.
[0007]
Further, in order to securely hold the opening / closing plate at the position where the ball hole is opened, a locking portion is provided on the opening / closing plate, and the locking portion is engaged at the position where the ball hole is opened on the support frame. It is good to provide the engaging part which stops.
[0008]
Furthermore, it is preferable to provide the drop hole in communication with the ball removal hole so that no pachinko balls remain in the drop hole.
[0009]

A game board 5 is provided on the rear side of the glass door frame 3, and an upper ball tray 6 is attached to the front surface of the front plate 4. 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.
[0020]
As shown in FIGS. 2 and 3, the lower ball tray 7 is divided into two parts, a dish part 8 that stores a large amount of pachinko balls and a cover member 9 that is attached to the upper part of the dish part 8. Then, a ball punching hole 11 for dropping a plurality of pachinko balls simultaneously at the substantially central position of the bottom wall 10 of the dish portion 8 is opened, and a plurality of pachinko balls are provided in the vicinity of the ball punching hole separately from the ball punching hole 11. An intrusion hole 12 is formed. Further, the bottom wall 10 is inclined downward toward the ball extraction hole 11 so that all the pachinko balls stored in the dish portion 8 are directed to the ball extraction hole 11. Reference numeral 13 denotes an opening / closing plate that opens and closes the ball hole 11 in the bottom wall 10 of the plate portion 8, and the opening / closing plate 13 is screwed to the bottom surface of the bottom wall 10 and the bottom surface of the bottom wall 10. And is urged in a direction to close the ball hole 11 by the elasticity of a spring 15 as an urging member built in the support frame 14.
[0021]
An operating portion 16 that protrudes outward from the notch recess 14a of the support frame 14 protrudes from the front edge of the opening / closing plate 13, and the opening / closing plate 13 can be moved by operating the operating portion 16 by hand. I am doing so. The opening / closing plate 13 has a closing plate portion 17 that closes the ball removal hole 11 and a ball receiving plate portion 18 that closes the drop-in hole 12 when the ball removal hole 11 is closed, and a locking portion 19 is provided at the right edge. Provided. The lower end edge of the locking portion 19 is a rounded surface to facilitate disengagement.
[0022]
As shown in FIG. 3, the support frame 14 is provided with a through hole 20 having a size substantially the same as that of the ball hole 11 at a position facing the ball hole 11. In addition, a support portion 21 that supports the opening / closing plate 13 when the ball hole 11 is closed and an engaging portion 22 that engages the locking portion 19 at a position where the opening / closing plate 13 opens the ball hole 11 are provided via a step 23. Is formed. The step 23 has a tapered surface so that the opening / closing plate 13 is smoothly closed.
[0023]
Next, the action of removing the balls from the ball tray will be described with reference to the drawings. As shown in FIG. 4, the normal opening / closing plate 13 closes the ball release hole 11 with the closing plate portion 17 and the drop hole 12 with the ball receiving plate portion 18 by the bias of the spring 15. In this state and when a large amount of pachinko balls are stored in the plate part 8 as shown in FIG. 6A, the operation part 16 is put on the finger to resist the bias of the spring 15. When the ball release hole 11 is moved to the opening side, the opening / closing plate 13 is detached from the support of the support portion 21 and moves downward along the tapered surface of the step 23 by the ball weight applied to the pachinko ball located in the drop-in hole 12. The ball hole 11 is opened while the pachinko ball of the dish 8 starts to fall from the ball hole 11 due to the inclination of the bottom wall 10. Then, as shown in FIG. 6B, when the opening / closing plate 13 is moved to a position where the ball removal hole 11 is opened, the opening / closing plate 13 is moved down by the ball weight applied to the pachinko ball located in the drop-in hole 12. The locking part 19 engages with the engaging part 22. Accordingly, even if the hand is released from the operation unit 16, the weight of the ball applied to the opening / closing plate 13 is greater than the urging force of the spring 15, and the opening / closing plate 13 stops to open the ball hole 11 as shown in FIG. Will be retained. Then, the pachinko balls in the dish portion 8 are extracted by dropping through the through holes 20 from the ball extraction holes 11.
[0024]
When the pachinko ball of the plate portion 8 is extracted in this manner and the weight of the ball applied to the opening / closing plate 13 from the drop-in hole 12 is reduced, the biasing force of the spring 15 is opened and closed as shown in FIG. The engagement between the locking portion 19 and the engaging portion 22 is released over the weight of the ball applied to the plate 13, and the opening / closing plate 13 moves backward to close the ball removal hole 11. At this time, the pachinko balls in the drop-in hole 12 are bounced up and returned to the plate portion 8 with the return force of the opening / closing plate 13.
[0025]
As described above, according to the first embodiment described above, when the opening / closing plate 13 is moved to the side where the ball hole 11 is opened, the opening / closing plate 13 is lowered by the weight of the pachinko ball located in the drop-in hole 12. The engaging portion 19 can be engaged with the engaging portion 22 and stopped and held at the ball removal position. Moreover, since the pachinko balls are extracted and the weight of the balls applied to the opening / closing plate 13 is reduced, the engagement of the opening / closing plate 13 is automatically released, so that an unnecessary open state of the opening / closing plate 13 can be prevented. Further, when it is desired to stop the ball removal in the middle, the operation portion 16 is slightly moved up against the weight of the ball applied to the opening / closing plate 13 to disengage, and the ball removal hole 11 is blocked by the urging of the spring 15. It is possible to easily remove a small amount of pachinko balls from the dish portion 8.
[0026]
Even if either one of the locking portions 19 or the engaging portion 22 is worn and cannot be engaged, the pachinko ball of the plate portion 8 is sphered without any trouble in the opening / closing operation of the ball punching hole 11. Can be removed. The engaging portion 22 may be a concave hole as shown in FIG. 7, and the engaging portion 19 protruding from the lower surface of the opening / closing plate 13 may be engaged.
[0027]
Next, with reference to FIG. 8 thru | or FIG. 10, the ball removal apparatus of the ball tray which concerns on 2nd Embodiment is demonstrated. The same components as those in the first embodiment will be described with the same reference numerals. In this embodiment, as shown in FIG. 8 and FIG. 9, the drop-in hole 12 has a size that allows a large number of pachinko balls to drop in at the same time. I am letting. Further, the rear right side of the opening / closing plate 13 is set as a locking portion 19, and the engaging portion 22 with which the locking portion 19 engages at the position where the opening / closing plate 13 opens the ball hole 11 at the rear of the support frame 14. As shown in FIG. 10, when the opening / closing plate 13 is opened, the rear of the opening / closing plate 13 is moved downward, and the locking portion 19 is engaged with the engaging portion 22 to open the opening / closing plate 13. Is held in a position where the ball hole 11 is opened.
[0028]
Thus, by providing the drop hole 12 in communication with the ball hole 11, no pachinko ball remains in the drop hole 12, and the opening / closing plate 13 is removed before the ball hole 11 is dropped. When the hole 11 is closed and the pachinko ball remains in the dish portion 8, if the opening / closing plate 13 is moved again in the opening direction, the opening / closing plate 13 does not have a ball weight superior to the urging force of the spring 15, The open / close plate 13 can reliably extract the remaining pachinko balls without locking. In the present embodiment, it has been described that the locking portion 19 is provided at the rear right end of the opening / closing plate 13, but the locking portion 19 may be used, for example, by using the operation portion 16 protruding outward from the support frame 14. The engagement portion 22 may be cut out and provided in the cutout recess 14 a of the support frame 14.
[0029]
Next, with reference to FIG. 11, a ball removal device for a ball tray according to a third embodiment will be described.

The support frame 14 is provided with a through hole 20a corresponding to the ball hole 11a, and a T-shape provided on the lower surface of the open / close plate 13 at a position where the open / close plate 13 opens the ball holes 11, 11a. An engaging portion 22 that engages with the locking portion 19 is provided. Since the engaging portion 22 has an arc shape and is always engaged with the locking portion 19 at one point, adjustment can be easily performed even if the open / close plate 13 is rattled during molding.
[0030]
Next, the action of ball removal will be described with reference to the drawings. Normally, as shown in FIG. 11A, the opening / closing plate 13 is supported by the support portion 21, and the ball removal holes 11, 11 a and the drop-in hole 12 are closed by the bias of the spring 15. When the opening / closing plate 13 is slid against the bias of the spring 15 as shown in FIG. 11B, the ball punching hole 11a is opened, and the pachinko ball is dropped from the through hole 20a. At this time, the opening / closing plate 13 is supported by the support portion 21 and the ball removal hole 11 and the drop-in hole 12 are closed. Further, when the opening / closing plate 13 is slid against the urging force of the spring 15, the opening / closing plate 13 is detached from the support portion 21 as shown in FIG. 11C, and a step is formed by the ball weight of the pachinko sphere located in the entrance hole 12. The locking part 19 engages with the engaging part 22 by moving down the taper surface of 23, and is stopped and held in a position where the ball punching holes 11 and 11a are opened, and the pachinko balls fall from the ball punching holes 11 and 11a. The balls are removed from the through holes 20 and 20a.
[0031]
In this way, when the pachinko ball of the plate portion 8 is extracted and the ball weight applied to the opening / closing plate 13 of the drop-in hole 12 is reduced, the engagement between the locking portion 19 and the engaging portion 22 is released, and FIG. The opening / closing plate 13 moves backward to the position shown in (a) and closes the ball removal holes 11 and 11a. At this time, the pachinko ball located in the drop-in hole 12 falls and is extracted from the ball-opening hole 11 communicating therewith. In this embodiment, if a small amount of pachinko balls are removed when exchanging premiums such as cigarettes during a game, if the state is removed in the state shown in FIG. 11B, the opening / closing plate 13 does not move down and does not lock. The pachinko ball can be pulled out without any extra effort. Further, since the pachinko balls are extracted from the plurality of ball extraction holes 11 and 11a, the pachinko balls of the dish portion 8 can be extracted quickly as a matter of course.
[0032]
FIGS. 12 to 15 show a fourth embodiment. Since the difference from the above embodiment is mainly the locking structure of the opening / closing plate 13, the same components will be described with the same reference numerals. . In this embodiment, the opening / closing plate 13 is provided with a plurality of first locking portions 19a and second locking portions 19b. The first locking portion 19a is formed to hang from the lower surface of the left end edge of the opening / closing plate 13, and the second locking portion 19b is formed to the right end edge of the opening / closing plate 13 as in the first embodiment. And the lower end edge of the 1st latching | locking part 19a and the 2nd latching | locking part 19b makes it easy to cancel | release engagement as a rounded surface. Further, the upper surface of the opening / closing plate 13 is an inclined surface facing the ball extraction hole 11 when the ball extraction hole 11 is closed.
[0033]
In addition, the first locking portion 19a and the second locking portion 19b are locked to the support frame 14 stepwise depending on the weight of the sphere on the opening / closing plate 13, with the ball release hole 11 being opened differently. The engaging portion 22a and the second engaging portion 22b are formed with a step difference in position.
[0034]
Next, with reference to the drawings, the action of ball removal of the ball tray of the fourth embodiment will be described. As shown in FIG. 13, the normal opening / closing plate 13 closes the ball release hole 11 with the closing plate portion 17 and the drop hole 12 with the ball receiving plate portion 18 by the bias of the spring 15. In this state and when a large amount of pachinko balls are stored in the plate portion 8 as shown in FIG. 15A, a finger is put on the operation portion 16 to resist the bias of the spring 15. When the ball punching hole 11 is moved to the opening side, the pachinko ball of the dish portion 8 starts to fall from the ball punching hole 11 while rolling on the upper surface of the inclined opening / closing plate 13. Then, as shown in FIG. 15B, when the opening / closing plate 13 is moved to a position where the ball punching hole 11 is almost fully opened, the weight of the pachinko sphere located in the drop-in hole 12 is applied to the opening / closing plate 13, whereby the opening / closing plate 13. Moves downward, and the first locking portion 19a engages with the first engaging portion 22a. Therefore, even if the hand is released from the operation unit 16, the weight of the ball applied to the opening / closing plate 13 is greater than the urging force of the spring 15, and the engagement between the first locking portion 19a and the first engagement portion 22a is maintained. As shown in FIG. 14, the opening / closing plate 13 is stopped and held in a state where the ball hole 11 is almost fully opened. Then, the pachinko balls in the dish portion 8 are extracted by dropping through the through holes 20 from the ball extraction holes 11.
[0035]
Thus, when the pachinko ball of the plate part 8 is extracted and the ball weight applied to the opening / closing plate 13 decreases, the biasing force of the spring 15 prevails over the ball weight applied to the opening / closing plate 13, and the first locking portion 19a and the first locking portion 19a. The engagement with the first engaging portion 22a is released, and the opening / closing plate 13 moves backward. As shown in FIG. 15C, the backward movement increases pachinko balls placed on the ball receiving plate portion 18. When the ball weight applied to the opening / closing plate 13 exceeds the urging force of the spring 15, the second locking portion 19 b engages with the second engaging portion 22 b, and the opening / closing plate 13 is stopped at a position where the ball extraction hole 11 is opened again. Hold. Further, when the pachinko ball of the plate portion 8 is extracted and the ball weight applied to the opening / closing plate 13 decreases, the biasing force of the spring 15 prevails over the ball weight applied to the opening / closing plate 13, and the second locking portion 19b and The engagement with the second engagement portion 22b is released, and the opening / closing plate 13 moves back to the position where the ball hole 11 is closed as shown in FIG.
[0036]
Thus, the pachinko balls can be made difficult to remain in the dish portion 8 by engaging the opening / closing plate 13 in a stepwise manner. Further, even if one of the locking portions 19a, 19b or the engaging portions 22a, 22b is worn and cannot be engaged, the other is engaged so that the opening / closing plate 13 is opened to the ball hole 11. Can be held in.
[0037]
FIG. 16 and FIG. 17 show a fifth embodiment. The drop-in hole 12 is provided in communication with the opening / closing plate 13 in the direction of closing the ball-out hole 11, and the ball-out hole 11 is formed in the ball-receiving plate portion 18. Is provided with an opening 24 of approximately the same size. A locking portion 19 is provided below the closing edge of the opening / closing plate 13, and an engaging portion 22 is provided at the opening end of the through hole 20 of the support frame 14. Note that the through hole 20 is formed in the same size as the ball hole 11 and the drop hole 12.
[0038]
Next, the action of removing the balls of the ball tray according to the fifth embodiment will be described with reference to the drawings. As shown in FIG. 16, the normal opening / closing plate 13 closes the ball removal hole 11 with the closing plate portion 17 by the bias of the spring 15, and closes the drop-in hole 12 with the ball receiving plate portion 18. In this state and when a large amount of pachinko balls are stored in the plate portion 8 as shown in FIG. 17A, the operation portion 16 is put on a finger to resist the bias of the spring 15 and the opening / closing plate 13 is moved. When the ball hole 11 is moved to the opening side, the pachinko ball of the dish portion 8 starts to fall from the ball hole 11 while rolling on the upper surface of the inclined opening / closing plate 13. Then, as shown in FIG. 17 (b), when the opening / closing plate 13 is moved to a position where the ball removal hole 11 is opened, the opening / closing plate 13 is moved down by the weight of the pachinko ball located in the drop-in hole 12, and the locking portion 19. Engages with the engaging portion 22 to stop and hold the open / close plate 13 in a state in which the ball hole 11 is opened. Then, the pachinko balls in the dish portion 8 are extracted by dropping through the through holes 20 from the ball extraction holes 11 through the openings 24.
[0039]
When the pachinko ball of the plate portion 8 is extracted in this way, the weight of the ball applied to the opening / closing plate 13 is reduced, and the urging force of the spring 15 prevails, as shown in FIG. The engagement with the joint portion 22 is released, and the opening / closing plate 13 moves backward to close the ball removal hole 11. At this time, the pachinko ball located in the drop-in hole 12 and received in the ball receiving plate portion 18 is pushed by the opening edge of the drop-in hole 12 along with the movement of the opening / closing plate 13 and through the through-hole 20. And is surely extracted without leaving a pachinko ball on the plate portion 8.
[0040]
As described above, the weight of the sphere applied to the opening / closing plate 13 can be adjusted by changing the shape and size of the drop-in hole 12, and the timing of disengaging the opening / closing plate 13 can be adjusted. It can also be adjusted by adjusting the urging force of the spring 15.
[0041]
【The invention's effect】
As is apparent from the above description, the ball removing device for the ball tray in the present invention uses the ball weight of the pachinko ball applied to the opening / closing plate to stop and hold the opening / closing plate at the ball removal position, and Since the ball weight of the pachinko ball applied to the opening / closing plate is reduced by the removal of the ball and the stop state of the opening / closing plate is automatically released, there is no need to perform a stop releasing operation. Therefore, it is possible to reliably prevent a situation in which the ball tray is left in a ball-out state due to mischief or carelessness.
[0042]
Furthermore, it can be configured with the conventional number of parts, and the structure is simple because no extra moving parts are required, and even if the open / close plate cannot be kept open due to some trouble, It is possible to remove the ball without any trouble.
