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開閉板を摺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、球受皿に貯留されるパチンコ球を利用して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す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、パチンコ球を貯留する皿部の底壁に球抜き孔を開設すると共に、底壁の下面に設けられる支持枠に球抜き孔を常に閉じる方向に付勢部材で付勢した開閉板を移動自在に設け、開閉板を球抜き孔を開放する位置に移動させることにより皿部のパチンコ球を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おいて、前記球抜き孔を開設した皿部の底壁にパチンコ球が落入する落入孔を穿設すると共に皿部下面に係合部を設け、開閉板には、前記落入孔に位置するパチンコ球の球重量により傾動して球抜き孔を開放する位置で前記係合部に係合する係止部を設け、球重量から解放されることにより、前記係止部の係合を解除して開閉板を球抜き孔を閉じる位置に自動復帰するようにした。
【０００６】
そして、前記支持枠に開閉板を支持する支持部を形成し、開閉板を該支持部を支点として傾動するようにするのが好ましい。
【０００７】
また、前記開閉板下面に支持片を設け、開閉板を該支持片を支点として傾動す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、皿部にパチンコ球が確実に残らないようにするために、前記開閉板が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、段階的に係合するようにするのが好ましい。
【００１０】
また、皿部にパチンコ球が残らないようにするために、球抜き孔の閉塞時にも前記開閉板の上面を閉塞側に傾斜した状態にするのが好ましい。
【００１１】
前記落入孔は、球抜き孔の閉塞側に連通して設けるのが好ましく、これによって皿部のパチンコ球を最後の１個まで確実に抜き取ることができる。
【００１２】
また、前記開閉板が支持される皿部の前面壁に係合部を設け、開閉板の操作部を係合部に直接的に係合させ、又は操作部に係止部を設けて係合部と係止部とを係合させることにより開閉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開閉板が傾動して係止部が皿部の係合部に係合し、開閉板を球抜き孔を開放する位置に確実に停止保持することができ、球抜き孔から球が抜けて、開閉板が球重量から解放されると開閉板の停止状態を自動的に解除して球抜き孔を閉塞する。また、前記落入孔の形状または大きさを変えることにより、落入孔に位置するパチンコ球量を変化させ開閉板の係合解除のタイミングをかえることができる。
【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。
【００１５】
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。
【００１６】
【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が装着されている。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の前面には上部球受皿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。
【００１７】
下部球受皿７は、図２および図３に示すように多量の余剰球を貯留する皿部８と該皿部８の上部に被着させるカバー部材９とにより形成されている。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と球抜き方向に連通して多数のパチンコ球を同時に落入させる大きさの落入孔１２を穿設している。また底壁１０は、皿部８に貯留されたパチンコ球がすべて球抜き孔１１に向うように下傾している。また、底壁１０下面には三角形状の係合部１３が設けられており、係合面は係脱しやすいように傾斜面としている。１４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１４は皿部８の底壁１０と該底壁１０下面にビス着される支持枠１５との間に移動自在に装着されており、付勢部材としてのスプリング１６によって常に球抜き孔１１を閉じる方向に付勢されている。
【００１８】
前記開閉板１４の前側縁には支持枠１５の切欠凹部１５ａから皿部８の外方に突出する操作部１７が突設されており、該操作部１７を手で操作することによって開閉板１４を移動し得るようにしている。また開閉板１４は、球抜き孔１１を閉じる閉塞板部１８と落入孔１２を閉塞する球受け板部１９を有すると共に、開閉板１４下面に前記スプリング１６の一端が嵌入する収納部２０が形成され、左端に前記係合部１３に係合する係止部２２を設けている。該係止部２２は開閉板１４の上面に突設して形成され、係止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１４の上面は、球抜き孔１１の閉塞時においても球抜き孔１１に向って傾斜した状態として、パチンコ球を抜き易くしている。なお、係止部２２は突設形成されたものに限られることなく、係合部１３が嵌まるような係止孔を穿設してもよい。
【００１９】
前記支持枠１５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２３が開設されている。また、該透孔２３を介して開閉板１４を支持する支持部２４ａ，２４ｂが段差を持って形成されており、該支持部２４ｂの中央溝部にスプリング１６の一端が嵌着するボス２５が形成されている。前記開閉板１４の先端部を支持する支持部２４ａは、球抜き孔１１の閉塞時に開閉板１４が滑らかに閉塞するように球抜き孔１１側をテーパー面としている。
【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。通常開閉板１４は図４に示すようにスプリング１６の付勢により球抜き孔１１を閉塞板部１８によって閉塞し、落入孔１２を球受板部１９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、スプリング１６の付勢に抗して操作部１７を指で球抜き孔１１を開放する側へ移動させると、開閉板１４は支持部２４ａの支持から外れ、皿部８のパチンコ球の球重量によって支持部２４ｂの角部２６を支点として傾動した開閉板１４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６（ｂ）に示すように、開閉板１４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１４が角部２６を支点として傾動した状態で、係止部２２が係合部１３に係合する。従って、操作部１７から手を離してもスプリング１６の付勢力より開閉板１４にかかる球重量の方が勝って、図５に示すように開閉板１４が球抜き孔１１をほぼ全開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２３を落下して抜き取られる。
【００２１】
このようにして皿部８のパチンコ球が抜き取られて、開閉板１４にかかる球重量が減少して、開閉板１４にかかる球重量よりスプリング１６の付勢力の方が勝ると、図６（ｃ）に示すように係止部２２と係合部１３との係合を解除し、開閉板１４が球抜き孔１１を閉塞する位置に自動的に復動することになる。
【００２２】
また、落入孔１２に位置するパチンコ球が球抜き孔１１から落下するよりも先に開閉板１４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、パチンコ球は開閉板１４の傾斜により球抜き孔１１側に位置しており、再度開閉板１４を開方向に移動すれば、開閉板１４にスプリング１６の付勢力に勝る球重量がかからないため、開閉板１４はロックされることなく残ったパチンコ球を抜き取ることができる。
【００２３】
なお、前記落入孔１２を球抜き孔１１と連通状に設けるようにしたが、球抜き孔１１と別に設けるようにしてもよい。また、開閉板１４を支軸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、或いは開閉板１４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、開閉板１４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７（ａ）〜（ｃ）は開閉板１４の下面に支持片２７を設けた球抜きを示したもので、図７（ａ）に示すように、支持片２７は開閉板１４が球抜き孔１１を閉塞しているときに支持部２４ａ，２４ｂのほぼ中央に位置しており、球抜き孔１１および落入孔１２のパチンコ球により開閉板１４が撓むのを防ぐと共に、図７（ｂ）に示すように球抜き孔１１の開放時に、該支持片２７を支点として開閉板１４が傾動するので、支持片２７の位置を変えることにより開閉板１４の傾斜角度を調節することができる。
【００２５】
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。この第２実施の形態の球抜き装置が第１実施の形態と異なるところは主として開閉板１４の傾動方向であるため、第１実施の形態と同じ構成のものには同一符号を付して説明する。開閉板１４は図８に示すように常にはスプリング１６により付勢され、後方に形成した突出片２８，２８を支持部２４ａ，２４ｂに支持させ球抜き孔１１を閉じるようにしている。また、皿部８の前面壁２９には係合部としての凹溝３０が設けられており、操作部１７上面には開閉板１４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３０に係合する係止部としての突起３１が突設されている。
【００２６】
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８および図１０（ａ）に示すように開閉板１４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１７に指を掛けて開閉板１４を図９に示す球抜き孔１１を開放する位置に摺動させると突出片２８，２８が支持部２４ａ，２４ｂから外れることになる。このため、この球抜き状態で操作部１７から指を離すと開閉板１４がスプリング１６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開閉板１４が図１０（ｂ）に示すように切欠凹部１５ａを支点として傾動して操作部１７の突起３１が皿部８の凹溝３０に係合する。従って、開閉板１４は図９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１７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。
【００２７】
一方、皿部８のパチンコ球が抜き取られて開閉板１４にかかる球重量が減少すると該開閉板１４は切欠凹部１５ａを支点として傾動し図１０（ａ）に示す位置に回動復帰する。このため、開閉板１４の操作部１７が下動して皿部８の凹溝３０と操作部１７の突起３１との係合が解除され、スプリング１６の付勢により開閉板１４が図８に示す球抜き孔１１を閉じる位置に自動復帰することになる。
【００２８】
この第２実施の形態の場合、例えば開閉板１４を球抜き可能な半開状態に摺動させたとき、突出片部２８，２８が支持部２４ａ，２４ｂから外れないようにすることにより、皿部８に貯留されるパチンコ球を開閉板１４を傾動させることなく少量ずつ球抜きしながら遊技を行うことができる。
【００２９】
また、前記した第２実施の形態では、皿部８の凹溝３０と開閉板１４の操作部１７の突起３１とを係合させることにより、開閉板１４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１１（ａ），（ｂ）に示すように凹溝３０を開閉板１４の操作部１７の横幅とほぼ等しくすることにより操作部１７と凹溝３０とを直接に係合させるようにしてもよい。
【００３０】
以上、説明した第１，第２実施の形態によれば、開閉板１４を球抜き孔１１を開放する側へ移動させると、開閉板１４が支持部２４の支持から外れ、落入孔１２に位置するパチンコ球の開閉板１４にかかる球重量によって該開閉板１４を下傾させる。そして、球抜き孔１１をほぼ全開する位置で係止部２２が係合部１３に係合して開閉板１４を停止保持することができる。しかもパチンコ球が抜き取られて開閉板１４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１４の係合を解除することができ、開閉板１４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１７を開閉板１４にかかる球重量に抗して少し上動すれば開閉板１４の係合が外れ、スプリング１６の付勢により球抜き孔１１を閉塞することができる。なお落入孔１２の形状や大きさを変えることにより、開閉板１４にかかる球重量の調節ができ、開閉板１４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１６の強さを代えることによっても開閉板１４の係合解除のタイミングを調整することができる。
【００３１】
図１２は第３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１４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。この第３実施の形態は、皿部８の底壁１０下面に複数の第１係合部１３，第２係合部１３ａを設け、開閉板１４にかかる球重量により、係止部２２が球抜き孔１１の開放状態を違えて段階的に係止するようになっている。
【００３２】
次に図面を参照して第３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１４は図１２（ａ）に示すようにスプリング１６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。そして、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１７に指を掛けて開閉板１４をスプリング１６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１４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１２（ｂ）に示すように、開閉板１４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によって開閉板１４が傾動し、係止部２２が第１係合部１３に係合する。従って、操作部１７から手を離してもスプリング１６の付勢力より開閉板１４にかかる球重量の方が勝って、係止部２２と第１係合部１３の係合が保持され、開閉板１４は図１２（ｂ）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２３を落下して抜き取られる。
【００３３】
こうして皿部８のパチンコ球が抜き取られて、開閉板１４にかかる球重量が減少すると、開閉板１４にかかる球重量よりスプリング１６の付勢力の方が勝って、係止部２２と第１係合部１３との係合が解除され、開閉板１４が復動するが、この復動により図１２（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１４にかかる球重量がスプリング１６の付勢力に勝って係止部２２が第２係合部１３ａに係合し、再度球抜き孔１１を開放する位置に開閉板１４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１４にかかる球重量が減少すると、開閉板１４にかかる球重量よりスプリング１６の付勢力の方が勝って、係止部２２と第２係合部１３ａとの係合を解除し、図１２（ｄ）に示すように開閉板１４が球抜き孔１１を閉じる位置に復動する。
【００３４】
このように、開閉板１４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、どちらか一方の係合部１３，１３ａ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１４を球抜き孔１１の開放位置に保持することができる。
【００３５】
図１３および図１４は第４実施の形態を示すもので、前記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、落入孔１２を球抜き孔１１の閉塞側に連通して設けるようにしたもので、球受け板部１９に球抜き孔１１とほぼ同じ大きさの開孔３２が設けられている。なお透孔２３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。
【００３６】
次に図面を参照してこの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１４は図１３に示すようにスプリング１６の付勢により球抜き孔１１を閉塞板部１８によって閉塞し、落入孔１２を球受板部１９によって閉塞している。図１４（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１７に指を掛けてスプリング１６の付勢に抗して開閉板１４を球抜き孔１１を開放する側へ移動させると、パチンコ球は球抜き孔１１から落下し始める。そして、図１４（ｂ）に示すように開閉板１４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によって開閉板１４が支持部２４ｂの角部２６を支点として傾動し、係止部２２が係合部１３に係合し、開閉板１４を球抜き孔１１をほぼ全開する状態に停止保持する。
【００３７】
そして、皿部８のパチンコ球が球抜き孔１１から開孔３２を介して透孔２３を落下して抜き取られると、開閉板１４が球重量から解放されて、図１４（ｃ）に示すように係止部２２と係合部１３との係合が解除され、開閉板１４が復動して球抜き孔１１を閉塞する。この時落入孔１２に位置して球受け板部１９に受けられていたパチンコ球は、開閉板１４の移動と共に落入孔１２の開口縁に押されて開孔３２を介して透孔２３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。
【００３８】
【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、その球重量から解放されるされると自動的に開閉板を球抜き孔を閉じる位置に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簡単に行うことができると共に、わざわざ停止解除操作をする必要がなく、球受皿を球抜き状態のまま放置されるような事態を防止することができる。
【００３９】
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。
