Description

【０００１】
【発明の属する技術分野】
本発明は、パチンコ球を球払出装置に導く供給樋等の裏機構部品の取付構造に関するものである。
【０００２】
【従来の技術】
パチンコ機は、周知のように、裏面側に球タンク等の裏機構部品が数多く設けられている。そして、該球タンクのパチンコ球を供給樋を介して球払出装置に導くように隣接して設けている。従来、前記供給樋は機構板の裏面に専らビスにより固着していた。このため、取付けに手間が掛かって作業能率を著しく低下させていた。そこで、本出願人により、そのビス止め作業をなくした出願がされている（例えば、特許文献１参照。）。

【０００４】
【発明が解決しようとする課題】
しかしながら、上記出願はビスをなくす効果はあるものの、誤って係止片が解除されると供給樋が一気に外れてしまうことがあり、再度供給樋を位置決めして取付けなければならなかった。
【０００５】
そこで本発明は、従来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、供給樋が誤って外れることのない取付構造を提供しようとするものである。
【０００６】
【課題を解決するための手段】
本発明は上記課題を解決しようとするもので、請求項１記載の発明は、パチンコ球を球払出装置に導く供給樋を基板に取付ける取付構造であって、前記供給樋を前記基板の表面に当接させ所定方向に摺動することにより係合する係合手段と、前記摺動に伴って前記供給樋を仮止状態と位置決め固定状態とで係止させ前記係合手段による係合状態が解離される方向への該供給樋の摺動を阻止する逆行阻止手段とを設けたことを特徴とする。ここでいう「摺動」とは、上下・左右・前後・斜め等のすべての方向の直線的移動の他に、一端又は中間部を支点として円弧状に移動することをも含む。
【０００７】
請求項２記載の発明は、請求項１記載の発明において、前記係合手段は、前記供給樋又は基板のいずれか一方に設けられる係合片と、他方に設けられ供給樋を摺動することにより前記係合片が係合する係合部とで構成されることを特徴とする。
【０００８】
請求項３記載の発明は、請求項１又は２記載の発明において、前記逆行阻止手段は、前記供給樋又は基板のいずれか一方に設けられる弾性係止片と、他方に設けられ前記弾性係止片が弾発力によって解離可能に係止される係止部とで構成されることを特徴とする。弾性付与手段として材質自体により弾性を付与するようにしても、別途スプリング，ばね等の弾性部材を介して係止方向への付勢を付与するようにしてもよい。
【０００９】
請求項４記載の発明は、請求項３記載の発明において、前記供給樋を仮止位置で前記係止部に係止させる第一係合部と、前記供給樋を位置決め固定する位置で前記係止部に係止させる第二係合部とを前記弾性係止片に設けたことを特徴とする。
【００１０】
請求項５記載の発明は、請求項３記載の発明において、前記係止部は、前記供給樋を仮止位置で係止させる第一係止部と、前記供給樋を位置決め固定させる位置で係止する第二係止部とからなることを特徴とする。
【００１１】
上記発明によれば、供給樋を所定方向に摺動させ係合手段を係合させるだけで、ビスを使用することなく供給樋をワンタッチで簡単に、しかも確実に取付けることができ誤って外れることがない。
【００１２】
前記供給樋の下流端に隣接して設けられる球払出装置が装着された状態において、該球払出装置が前記供給樋によって取外しができないように構成するのが好ましい。例えば、前記球払出装置は下方に摺動することによって取付けられ、前記供給樋を球払出装置が外れる方向（上方）への移動を阻止するように取付けることによって、球払出装置の外れる方向への移動が阻止されて取外すことができなくなり、供給樋が球払出装置の取外阻止手段となる。また、前記供給樋を固着した状態で球払出装置の取外し方向への移動を阻止する取外阻止片等を別途設けるようにしてもよい。そして、好ましくは前記供給樋の仮止状態で球払出装置が取外し可能となるようにするのがよい。
【００１３】
また、供給樋を複数に分割形成して、分割した一つの供給樋を装着した状態において、先に装着した供給樋が隣設する供給樋によって取外しできないようにしてもよい。
【００１４】
また、球払出装置等の裏機構部品を基板に取付ける取付構造であって、前記裏機構部品を前記基板の表面に当接させ所定方向に摺動することにより係合する係合手段と、前記摺動に伴って前記裏機構部品を仮止状態と位置決め固定状態とで係止させ前記係合手段による係合状態が解離される方向への該裏機構部品の摺動を阻止する逆行阻止手段とを設けた。また、裏機構部品が隣接する取付構造であって、一方の裏機構部品を前記取付構造で固着した際に、該裏機構部品に他方の裏機構部品が外れる方向への移動を阻止する取外阻止手段を設けるのが好ましい。ここでいう「裏機構部品」とは、球タンク，供給樋，球払出装置等パチンコ機の裏面側に着脱自在に設けられるものである。
【００１５】
【発明の実施の形態】
次に、本発明の一実施の形態を図面を参照して説明する。図１はパチンコ遊技機の裏面図である。図において、１はパチンコ遊技機の外枠、２は外枠１の前面に開閉自在に装着される前面枠であり、該前面枠２の裏面側に遊技盤取付枠３が一体に設けられている。４は遊技盤取付枠３に着脱自在に取着された遊技盤である。
【００１６】
前記前面枠２の裏面には、前記遊技盤４の後面を覆うようにその略中央に開口窓６が開設され、多くの裏機構部品を取付ける基板としての機構板５が配設されている。裏機構部品として前記開口窓６の上方に球タンク７が固着されており、該球タンク７の下方には、該球タンク７に貯留されたパチンコ球を整列して後述する球払出装置１１に導く供給樋８が設けられている。該供給樋８は、前記開口窓６の上方に位置する傾斜樋９と開口窓６の側方に位置する屈曲樋１０とで構成される。そして、その屈曲樋１０の下端には球払出装置１１が設けられ、その下方には、球払出装置１１から払出されたパチンコ球を図示しない前面枠２の前面の打球供給皿に導く排出通路１２と、打球供給皿の余剰球を図示しない下部球皿に導く余剰球通路１３と、球抜き通路１７とが形成され、その上面に払出制御基板１４が取着されている。一方、前記開口窓６の下方には入賞球集合樋１５が設けられ、その裏面に遊技内容を制御する制御主基板が内部に装着された基盤ボックス１６が設けられている。
【００１７】
前記球タンク７は、図２及び図３に示すように底部２０及び前後左右の四側壁１８，１９，２３，２４により上面が開口する平面略長方形の箱状に形成され、底部２０が一側壁（図上左側壁２３）に向って緩やかに下傾しており、その下流部であり前記傾斜樋９の上流始端部分に位置して、複数のパチンコ球が同時に流出し得る大径の導出口２１が開設され、該導出口２１の一側方（後面壁１９側）にパチンコ球の球心を支持する程度の球崩し部２２を形成している。該球崩し部２２の上面は前記導出口２１に向って緩やかに傾斜している。また、左右両側壁２３，２４の外面に、取付片２５，２６を一体に設けており、一方（図上右側）の取付片２６には透孔２７が穿設され、他方（図上左側）の取付片２５は球タンク７のほぼ前端に位置して設けられ、係合孔２８が形成されている。２９ａ及び２９ｂは底部２０下面に設けられ、傾斜樋９の側壁３２及び前面壁１８を押える押え片である。
【００１８】
前記傾斜樋９は、図２及び図４に示すように前後側壁３０，３１及び左側壁３２，底壁３３とにより樋状に形成され、始端部を前記導出口２１からのパチンコ球を受ける球受部とし、該始端部から次第に断面凹溝状となる主流路３４が形成され、その側方に該主流路３４の途中で合流する副流路３５が、主流路４６の傾斜より緩い傾斜によって形成される段差を介して該主流路３４の底壁３３より高い位置が支持面となるように拡幅状に並設され、合流部でほぼパチンコ球１個の段差を有している。該副流路３５の終端コーナー部には図４に示すように段状の棚部３６ａ，３６ｂによって球逃し部３７が設けられている。該球逃し部３６のそれぞれの棚部３６ａ，３６ｂの段差はパチンコ球の球心を支持する約６ｍｍとしており、下段の棚部３６ａは円弧状面によりパチンコ球が支持されない幅員として、上段の棚部３６ｂは緩やかに副流路３５側に下傾している。なお、最下段の棚部３６ａの始点を角部とすることでも副流路３５の流速を抑制することができる。前記主流路３４は、始端部を約２０ｍｍとしてパチンコ球がジグザグ状にランダムに流下し得る通路幅とし、下流側を徐々に絞って約１２ｍｍの通路幅としている。さらに、該狭窄部は図５に示すように折れ点を介して底部が内面緩やかな円弧状に形成され、該円弧状通路部は上流側の勾配を下流側の勾配よりも大きく設定され、パチンコ球の流下速度を瞬間速めて球詰りを防止するようにしている。そして、パチンコ球は円弧状通路部の終端から後述する屈曲樋１０の供給通路１０ａに放出するように流下する。４０は傾斜樋９の終端に固設される球均し蓋であり、４１はパチンコ球の有無を検知する検知センサである。また、傾斜樋９の上流端に取着片４２が設けられ、該取着片４２に係合孔４３が開設されている。また、前記副流路３５の下流端壁に該傾斜樋９の撓みを防止する係止部材４５が係止する鉤状の突起４６が形成されている。
【００１９】
一方、前記機構板５の裏面上部には、図３に示すように球タンク７の取付部５０が凹状に形成されている。この取付部５０は、球タンク７を機構板５に装着する際に球タンク７の後半部分を嵌合して位置決めすると共に、両側２３，２４及び底部２０の一部と後面壁１９の上端を支える機能を有する。また、前記取付部５０の側方に位置して球タンク７の取付固定部５１，５２を突出形成している。一方（図上右方）の取付固定部５２は、一側が開放した袋状に設けられると共に前面に前記透孔２７に合致する貫通孔５３を開設している。他方の取付固定部５１は、傾斜樋７の取付部を兼用して、球タンク７及び傾斜樋９の撓みを防止するように、別体に形成した取付部材５５によって機構板５の板状部から５ｃｍ程突出して設けられている。前記取付部材５５は、図６に示すように取付部材５５の本体部の後面に、取付固定部５１に形成されている係止部５６に係止する下向きＬ型の鉤片５７が設けられ、下部に取付固定部５１の下端に係止する湾曲状の弾性係止片５８が形成されている。そして、取付部材５５には、球タンク７の取付片２５及び傾斜樋９の取着片４２が受けられる凹部５９，５９が形成されると共に該凹部５９に前記係合孔２８，４３が係止する外向きＬ字状の係止片６０を設けている。該取付部材５５は、取付固定部５１の開口５１ａから鉤片５７を臨ませ該取付固定部５１の前面に衝止させると、前記弾性係止片５８が撓み、この状態で該取付部材５５を下方に押し下げると、前記鉤片５７が係止部５６に係止すると共に前記弾性係止片５８が弾性復帰して取付固定部５１の下面に係止し、取付部材５５が取付固定部５１に固着される。なお、図上取付部材５５の本体部から腕部の下面がほぼ９０°になるように延設して該腕部に鉤片５７を垂設するようにしたが、腕部を下面が取付部材５５の本体部から下向き鋭角となるように設けて、鉤片５７を鉛直方向に設けるのがよく、取付部材５５に掛かる荷重に対して外れ難くすることができる。また、取付固定部５１及び取付部材５５の上面は、万一パチンコ球が載っても滞留しないように後面側（図６上右方向）に下傾させるのがよく、さらに好ましくは、取付固定部５１及び取付部材５５の上面を球タンク７側に下傾させて、前記パチンコ球が球タンク７内に入るようにするのがよい。より確実に球タンク７に導くために、取付固定部５１又は取付部材５５から球タンク７に臨むように誘導片を延設するようにしてもよい。
【００２０】
また、図４に示すように傾斜樋９の下流側に位置させて、該傾斜樋９の後面壁３１端部に設けられた差込片６２が挿通係止する開口６３を設けている。また、前記袋状の取付固定部５２の近傍に、傾斜樋９の撓みを防止する係止部材４５の一端が係止する係合孔６４が設けられている。前記係止部材４５は、図２及び図７に示すように基部６５を前記取付固定部５２に嵌る形状とすると共に前記透孔２７に貫挿する挿通片６６が設けられ、先端に前記鉤状突起４６に係合するコ字状の掛止部６７が形成され、他端に前記係合孔６４に係止する鉤片６８が形成される。
【００２１】
なお、前記取付部材５５を設けることなく、機構板５に所定高さの取付固定部５１を立設するようにしてもよいが、実施の形態に示すように高さがあるため、機構板５の成形及び保管上別途形成するのが好ましい。また、取付部材５５に球タンク７及び傾斜樋９を係止する係止片６０を設けることにより、万一該係止片６０が損傷しても取付部材５５のみを交換すればよく、機構板５全体を交換することがなく無駄をなくすことができる。
【００２２】
上記構成の球タンク７及び傾斜樋９の取付けは、次の如く行われる。先ず、傾斜樋９の取着片４２の係合孔４３に取付固定部５１の係止片６０を臨ませると共に、差込片６２を開口６３に臨ませて機構板５に当接させる。そして、この状態から傾斜樋９を下流側へスライドさせると、図４に示すように下流側の差込片６２が前記開口６３端に係止すると共に前記係止片６０が係合孔４３に係合する。次に、図３鎖線に示すように球タンク７の取付片２５の係合孔２８を取付固定部５１の係止片６０に臨ませて、該球タンク７を取付部５０に収納する。そして、この状態で右方へスライドさせると、取付片２６が袋状の取付固定部５２に受入れられると共に、係止片６０が係合孔２８に係合する。このとき、押え片２９ａで傾斜樋９の側壁３２を押えて該傾斜樋９の抜脱方向への移動を阻止すると共に押え片２９ｂで傾斜樋９の前面側への撓みを防止する。この状態で、前記係止部材４５の鉤片６８を係合孔６４に係合させると共に基部６５を取付固定部５２に被せ、挿通片６６を前記貫通孔５３を介して取付片２６の透孔２７に貫挿させ、先端の掛止部６７を前記鉤状突起４６に係合させる。これにより、球タンク７及び傾斜樋９の外れる方向への移動が阻止され、ビス着することなく球タンク７及び傾斜樋９を取付けることができると共に傾斜樋９の撓みを防止することができる。このとき、球タンク７の取付方向と前記取付部材５５の取付方向が左右方向に対して上下方向と双方異なっているため、常態では当然取付部材５５の取付方向に負荷が掛かり外れることはなく、機構板５の運搬時に球タンク７を持って該球タンク７が上方に持ち上げられたとしても、該球タンク７が凹状の取付部５０に嵌って後面壁１９により上方への規制がなされるため、取付部材５５が上向き方向に外れる構造であっても上方に持ち上げらることがないため、取付部材５５が抜脱することがなく、球タンク７が確固と保持される。
【００２３】
前記屈曲樋１０は、図８乃至図１０に示すように上流側を緩やかな湾曲状に形成し直線状部を介して下流側を連続して屈曲させている。そして、コ字状に一側を開放した供給通路１０ａを一体に形成した裏枠体８９に、該開放側を表枠体９０で閉塞することで構成され、裏枠体８９に表枠体９０を被せることで表枠体９０の係止孔９０ａが裏枠体８９の係止爪８９ａに係止して組み付けられる。前記係止孔９０ａ部は周縁にスリットを設けることにより弾性を付与している。また屈曲樋１０は、上流から下流にかけて通路幅を約２０ｍｍから徐々に逓減して１２ｍｍとしている。そして、供給通路１０ａの内側壁に沿って設けられる溝部９１に薄肉の鉄板９２を沿設して、パチンコ球の流下による摩耗を防止すると共に静電気除去の役割を果たしている。また、前記表枠体９０にゴミ落しを兼ねて前記鉄板９２の嵌り具合を調整確認する開孔９３が設けられ、裏枠体８９のフランジ部には該屈曲樋１０の取着用の係合手段としての係合片９４が複数設けられ、下流側はフランジ部自体を係合片９４ａとしている。該屈曲樋１０の上面に位置する係合片９４は、後述する係合部９５が貫挿する開口９６を介して設けられている。なお、係合片９４は長さを違えて係合部９５との係合のタイミングをずらすようにしている。また、前記係合手段が一部係合する仮止位置と、さらに係合手段が係合し位置決め固定される位置とで係止して、該屈曲樋１０の抜脱方向への移動を阻止する逆行阻止手段が設けられている。前記逆行阻止手段として、屈曲樋１０には該屈曲樋１０を機構板５に仮止め位置で係止する第一係止手段と、機構板５に位置決め固着する位置で係止する第二係止手段が設けられている。前記第一係止手段として、前記裏枠体８９に、機構板５に対して交差する前後方向に弾性を付与した仮止係止片９７が設けられている。該仮止係止片９７は、裏面に上向き傾斜状の係止爪９７ａを有し、先端を湾曲して指掛用の操作部９７ｂが設けられている。また、第二係止手段として、前記表枠体９０に機構板５の板面に沿って撓んで係止するように先端を係止部９８ａとして、下方を湾曲させて弾性を付与した略し字状の固定係止片９８を設けている。そして、前記仮止係止片９７及び固定係止片９８はそれぞれ規制片９９により撓み量を規制しており、撓み過ぎにより仮止係止片９７及び固定係止片９８の弾性が無くなることを防止するようにしている。なお、この実施の形態において、前記仮止係止片９７及び固定係止片９８の弾性付与方向を異ならせるようにしたが、弾性付与方向を同一方向としてもよい。
【００２４】
一方、屈曲樋１０の取着部Ｓ１には、前記係合片９４を上方から受入れ係合する係合部として上方が開放した袋状の係合受部９５が設けられ、前記係合片９４ａが係合する断面Ｌ字状の係合部１００が設けられている。また、前記仮止係止片９７及び固定係止片９８が係止する被係止部として、爪状の仮止係止部１０１及び段状の固定係止部１０２が設けられている。該固定係止部１０２は、固定係止片９８の係止部９８ａが段部に係止した際に、固定係止片９８本体を規制支持するリブ壁１０２ａが固定係止片９８本体に沿うように設けられる。なお、屈曲樋１０の取着部Ｓ１には、該屈曲樋１０の外周縁に当接し得るように突設され、該屈曲樋１０の係合方向を規制するガイドリブ１０３が設けられている。
【００２５】
次に、図８及び図１１を参照して球払出装置１１の構成について説明する。球払出装置１１は、箱枠状のケース体７０に前記屈曲樋１０の供給通路１０ａと連通する球通路７１と、該球通路７１に臨み最先のパチンコ球を制御支持しパチンコ球の荷重により回転する払出回転体７２と、前記払出回転体７２の回転を制御する制御手段７３とを備え構成している。前記ケース体７０の一側には、該球払出装置１１を機構板５に取着するための取着片７３が突設されると共に規制リブ７４が形成されている。前記取着片７３は、コ字状として強固なものとしている。また、機構板５側の側壁に切溝状の係止溝６１が上下に位置して形成されている。
【００２６】
前記球通路７１は、図１１に示すように前記屈曲樋１０の供給通路１０ａと連通する流入通路部７１ａと、パチンコ球が払出回転体７２に支持されて移送する移送通路部７１ｂと、前記払出回転体７２の支持から外れて払出される排出通路部７１ｃと球抜通路部７１ｄとで構成されている。前記流入通路部７１ａは、前記払出回転体７２に回転力を付与するように緩やかに湾曲させている。
【００２７】
７５は前記排出通路部７１ｃに払出されたパチンコ球を検出するセンサであり、該センサ７５は発光部と受光部とからなる光学式センサで、しかも排出通路部７１ｃの中心線からずれた位置でその光軸が交差するように配置される。そして前記払出回転体７２による拘束から解放されたパチンコ球が光軸を遮ることで該パチンコ球を検知し得るように配置される。
【００２８】
前記払出回転体７２は、図１１に示すように外周に凹凸部としての凹凸歯７６，７７を複数（本実施の形態において５個）設けたスプロケットタイプで、前記球通路７１内でパチンコ球を凹歯７６で受入れて、該パチンコ球の重量が該払出回転体７２に回転トルクを及ぼすように軸支７８して、パチンコ球を凹凸歯７６，７７で支持しパチンコ球を自重で流下させることにより、順方向に従動回転するようにしている。前記凸歯７７の頂点から背面にわたり、払出回転体７２の回転中心７８からの距離が漸次減少する巴形状として、凸歯７７で支持されたパチンコ球を凹歯７６に素早く受入れるようにしている。このため、高速回転による払出しに対応することができる。
【００２９】
前記制御手段７３は、図１１に示すように前記払出回転体７２の軸方向側方に位置して前記凹凸歯７６，７７と同ピッチで放射状に突出して設けられる制御用突出体としての立壁７９と、電気的駆動源としてのソレノイド８０の作動によって前記立壁７９，７９間に進退動し払出回転体７２の回転停止制御を行う作動体８１とを備えている。前記作動体８１には前記立壁７９の後面に接触して前記払出回転体７２を定位置に規制する帯状の規制部８１ａが形成されている。
【００３０】
また、前記球払出装置１１には球抜き装置８２が設けられている。該球抜き装置８２は、排出通路部７１ｃと球抜通路部７１ｄとを切替える切替弁８３と該切替弁８３を作動させる作動部材８４とで構成され、該作動部材８４には前記ソレノイド８０のプランジャ８０ａを強制的に作動させる操作部８５を有している。前記切替弁８３は、払出回転体７２の下方に位置して排出通路部７１ｃと球抜き通路部７１ｄとを切替えるように回動自在に軸支され、該切替弁８３の一端に形成された軸ピン８３ａを前記作動部材８４に形成された長孔８４ａに遊嵌し、作動部材８４をスライドさせることで切替弁８３が回動するようにしている。８６ａ，８６ｂは作動部材８４の常態位置と球抜き位置とを規制する位置決め突起である。抜き操作は、図１１鎖線に示すように前記作動部材８４を操作して上動させると、前記長孔８４ａ及び軸ピン８３ａとの連繋により、切替弁８３が回動すると共に操作部８５が上動し、該操作部８５が前記ソレノイド８０のプランジャ８０ａを強制的に上動して、作動体８１を作動させて立壁７９との係合を解除し、払出回転体７２をフリー状態として球荷重により回転させてパチンコ球を排出通路部７１ｃに排出し、切替弁８３により切替えられた球抜通路部７１ｄに該パチンコ球を導き球抜きする。このとき、作動部材８４は前記位置決め突起８６ｂにより位置決めされ球抜き状態を維持している。このように、作動部材８４を操作すると切替弁８３を切替えると共にソレノイド８０のプランジャ８０ａを強制的に上動させることができるので、球抜きを手動で行うことができ、球抜き時にわざわざソレノイド８０に通電して励磁させる必要がない。
【００３１】
一方、前記機構板５に設けられた球払出装置１１の取着部Ｓ２には、該球払出装置１１を挟持するように立設する保持片８８がほぼ対向するように設けられ、一方（図上右側）の保持片８８に前記取付片７３が上方から嵌合する係合凹部８７が形成されている。そして、前記規制リブ７４は該保持片８８の端部で支持される。また、他側（図上左側）の保持片８８近傍に前記係止溝６１に係止する鉤状の係止片６９が設けられている。
【００３２】
次に、上記屈曲樋１０及び球払出装置１１の取付けについて説明する。先ず、球払出装置１１の取付けは、図１２に示すように機構板５の係合部８７の上方に前記取付片７３を臨ませると共に前記係止溝６９を係止片６９の上方に位置するようにケース体７０の側面を取着部Ｓ１に当接させ、この状態で下方にスライドさせる。すると、図１１及び図１３に示すように前記係止片６９が係止溝６１に係合すると共に、前記取付片７３が係合部８７に係合し保持片８８によりケース体７０が保持され、球払出装置１１は前記係合を解除する上方への移動以外は規制阻止され取着部Ｓ１に取付けられる。
【００３３】
次に、屈曲樋１０を取付けるには、図１３に示すように屈曲樋１０を前記係合片９４，９４ａを係合受部９５及び係合部１００の上方に位置して臨ませる。このとき、図１４（イ）に示すように前記第一係止手段の仮止係止片９７が仮止係止部１０１に衝止して押圧され弾性により撓んだ状態となる。この状態で屈曲樋１０を前記ガイドリブ１０３に沿わせながら下方に摺動させると、図１３及び図１５（イ）に示すようにて前記係合片９４の一部が係合受部９５に嵌り込むと、図１４（ロ）に示すように前記仮止係止片９７が仮止係止部１０１の押圧から開放され、仮止係止片９７が弾性復帰して係止爪９７ａが仮止係止部１０１に係止し屈曲樋１０の上動を阻止し、屈曲樋１０が無用に外れない仮止め状態となる。このとき、前記固定係止片９８は、図１３に示すように固定係止部１０２との接触により撓んだ状態となっている。そして、さらに屈曲樋１０を下方に摺動すると、図１５（ロ）に示すように前記係合片９４が係合受部９５に完全に受入れられて係合する。同時に、前記第二係止手段の固定係止片９８は、固定係止部１０２に接触して撓みながら下動して該固定係止部１０２の段部に弾発係合し、これにより屈曲樋１０は上動を阻止され所定位置に位置決め固定される。そして、屈曲樋１０はビス着することなく取付位置の精度が保たれ、ガタつきや位置ずれを起すことなく取着される。同時に前記球払出装置１１は屈曲樋１０によって上方への移動が阻止されて、取外すことができなくなる。なお、係止手段を弾性係止片９７，９８及び係止部１０１，１０２により構成することにより、弾性係止片９７，９８が係止部１０１，１０２に弾発係止する際に係止音が発生し係止状態を聴覚（耳）により確認することができる。
【００３４】
上記のように取着した球払出装置１１を機構板５から取外すには、先ず屈曲樋１０の第二係止手段の固定係止片９８を弾性に抗して操作して、固定係止部１０２との係合を解除し、この状態で屈曲樋１０をガイドリブ１０３に沿わせて上動させると、図１４（ロ）に示すように第一係止手段の仮止係止片９７が仮止係止部１０１に衝止して上動が阻止される。このとき、図１５（イ）に示すように係合片９４がまだ係合受部９５に受入れられた仮止め状態にあり、該屈曲樋１０は外れることはなく機構板５から取外すことはできない。また、球払出装置１１の上動を阻止していた屈曲樋１０が上動したことにより、該球払出装置１１の上端と屈曲樋１０の下端との間に、球払出装置１１の係止位置から解除位置までの移動距離を有する隙間が生じる。そして、球払出装置１１の上動がフリーとなった該球払出装置１１を前記隙間内で上方に押し上げると、取付片７３と係合部８７との係合が解除されると共に、係止片６９が係止溝６１から外れ、該球払出装置１１を機構板５から簡単に取外すことができる。
【００３５】
次に、屈曲樋１０を取外すには、図１３に示す前記第二係止手段９８，１０２の係合を解除した状態で、第一係止手段の仮止係止片９７を付勢力に抗して操作し、仮止係止部１０１との係合を解除すると共に屈曲樋１０を上動させて、図１５（イ）鎖線に示すように係合片９４と係合受部９５との係合を解除することで取外すことができる。なお、当然のことながら必要に応じて球払出装置１１を取外すことなく、屈曲樋１０のみを取外すことができる。
【００３６】
このように、屈曲樋１０は第一係止手段が係止する仮止め状態があるので、第二係止手段の係合を解除した状態で屈曲樋１０を勢いよく上動させても第一係止手段が係止するので不用意に外れることがなく、取付けなおす手間が掛からない。特に、位置決め固定状態を解除する第二係止手段と仮止め状態を解除する第一係止手段が、別々の箇所に位置を違えて設けられているため、誤って仮止め状態を解除することはない。
【００３７】
なお、実施の形態において、前記屈曲樋１０を仮止め状態として球払出装置１１を取外す際に、供給通路１０ａのパチンコ球が球零れしないようにする球止手段を設けるのが好ましい。例えば、屈曲樋１０下端に供給通路１０ａ内に突入する球止弁を設けたり、機構板５に屈曲樋１０を仮止め状態に移動したときに自重又は弾性により該屈曲樋１０の下端に臨む球止め片又は球止部材を設けたりする等考えられる。また、屈曲樋１０と傾斜樋９間の球止めは、屈曲樋１０の上流端部で行うことができる。
【００３８】
また、逆行阻止手段を第一係止手段と第二係止手段と複数箇所に設けた際には、どちらの係止手段が仮止め解除か固定解除かが判別し得るように、その設置箇所に対応して、機構板５又は供給樋１０の表面に操作順序を示す番号或いは文字を表示し、誤操作しないようにするのが好ましい。
【００３９】
前記実施の形態において、屈曲樋１０の取付けを上下方向の摺動により取着するようにしたが、その方向性は限定されるものではなく、左右又は斜め，前後方向であっても、一端を支点として円弧状に摺動するようにしてもよい。例えば、図１６に示すように球払出装置１１の取付を左右の摺動による取付として、屈曲樋１０をほぼ中心を支点として回動状に摺動させて取付けるようにしている。具体的には、屈曲樋１０の背面中央に中空軸筒部１０５を形成し、下流端に球払出装置１１の取外しを阻止する阻止手段としての押え片１０６を、該球払出装置１１の取外し方向である側方を押えるように設けている。一方、屈曲樋１０の取着部Ｓ１には前記中空軸筒部１０５に対応位置して筒状軸部１０７を設け、屈曲樋１０の前面及び側面を保持する係合手段としての逆Ｌ字状の位置決め保持片１０８が設けられる。そして、機構板５の取着部Ｓ１にスリットを開設することにより弾性を備え、仮止め状態に係止する仮止係止部１０９及び屈曲樋１０を位置決め固定する固定係止部１１０が設けられる。前記仮止係止部１０９及び固定係止部１１０は、常に機構板５の表面から先端爪部１０９ａ，１１０ａが突出しており、これが屈曲樋１０の押圧から開放されると弾性復帰して屈曲樋１０の側壁に係止する。前記位置決め保持片１０８は、屈曲樋１０を組付ける係止孔９０ａに対応位置して設けるのが好ましく、位置決め保持片１０８により組付け解除方向への撓みを防止することができ、屈曲樋１０の組付けがより強固なものとなる。
【００４０】
なお、この実施の形態の球払出装置１１の取付けは、球払出装置１１を横摺動して取付片７３を係合部８７に係合して取付けられる。次に、上記屈曲樋１０の取付けは、位置決め保持片１０８を避けて図１６（イ）鎖線位置で前記仮止係止部１０９を押圧するように、屈曲樋１０の中空軸筒部１０５を前記筒状軸部１０７に貫挿して位置決めし、同図矢印に示すように図上反時計回り方向に回動するように摺動する。すると、図１６（イ）実線に示すように屈曲樋１０の前面一部が前記位置決め保持片１０８の下面に入り込むように係止して前面側への移動を阻止され、前記仮止係止部１０９が屈曲樋１０の押圧から開放されて先端爪部１０９ａが弾性復帰し、屈曲樋１０の復動が阻止され仮止め状態となる。そして、さらに屈曲樋１０を、前記固定係止部１１０を押圧しながら図１６（ロ）実線位置に摺動させると、前記固定係止部１１０が屈曲樋１０の押圧から開放されて先端爪部１１０ａが弾性復帰し、屈曲樋１０の側部に係止すると共に保持片１０８で完全に保持され位置決め固定される。このとき、押え片１０６で前記球払出装置１１の側方を押え、該球払出装置１１の取外し方向への移動を阻止する。なお、屈曲樋１０の軸支位置は任意に変更可能であり、上流端であってもよく、回動方向も特に限定されるものではない。また、球払出装置１１の取付方向は限定されるものでなく、前後方向であってもよく、このとき屈曲樋１０に前後方向への移動を阻止する取外阻止手段を設けるようにすればよい。また、この実施の形態において設ける球止手段としては、屈曲樋１０が図１６（ロ）実線位置から図１６（イ）実線位置の仮止め状態に移動する際に、該屈曲樋１０の下端に位置して供給通路１０ａのパチンコ球を支持して球止めする球止壁を機構板５に立設すればよい。このとき、当然前記押え片１０６と球止壁とは干渉しない高さが選ばれる。なお、屈曲樋１０と傾斜樋９間の球止めは、図１６（イ）実線に示すように屈曲樋１０の上流端部で行うことができる。
【００４１】
図１７及び図１８は他の実施の形態を示し、前記実施の形態と異なる点は屈曲樋１０の取付けによって、傾斜樋９の取外しができないように取外阻止手段を設けた点であり、同じ構成要素には同一符号を付して説明する。この実施の形態では、取外阻止手段として屈曲樋１０の傾斜樋９との接続部に傾斜樋９の前面壁３０を押える押圧片１１１が設けられ、傾斜樋９の前面壁３０端部に屈曲樋１０の摺動方向の係止リブ１１２が設けられる。該押圧片１１１は、裏面に前記係止リブ１１２に掛止めするコ字状の係止溝１１３が形成され、図１７（イ）に示す屈曲樋１０の仮止め状態では傾斜樋９と干渉することはない。さらに、屈曲樋１０を摺動させて、図１７（ロ）に示す第二係止手段が係止した状態で傾斜樋９の前面壁３０を押圧するように臨み、図１８に示すように係止溝１１３が係止リブ１１２に係止して、傾斜樋９の取外し方向（図上左方向）への抜脱を確実に阻止すると共に該傾斜樋９の撓みを防止する。なお、前記押圧片１１１に係止リブを設けて、傾斜樋９の前面壁３０端部に係止溝１１３を形成するようにしても、同様の効果を奏する。また、この実施の形態において、傾斜樋９を左方への取外しとしたが、前方であってもよく、また上方への取外しの際には、傾斜樋９の上方への移動を阻止する阻止片を設けるようにすればよい。好ましくは屈曲樋１０と傾斜樋９の取外し方向を異ならせるのがよく、より確実な阻止能力を有することになる。
【００４２】
また、前記係合手段を屈曲樋１０に設けた係合片と機構板５に設けた係合受部としたが、実施の形態に限定されるものではなく、互いに逆に設けるようにして下向き開口した係合受部を上向きの係合片に係合させるようにしてもよい。さらに、係合手段は頭部を有した突部と掛止孔であってもよく、摺動して係合する種々な方法が考えられる。
【００４３】
なお、前記逆行阻止手段として、第一係止手段及び第二係止手段を弾性を付与した係止片として供給樋８側に設けたが、機構板５にスリット等を設けることにより係止部に弾性を付与するようにしてもよい。また、逆行阻止手段として係合する係止部及び被係止部のいずれか一方に材質自体の弾性により係止方向への付勢を付与するようにしたが、弾性付与手段として、別途スプリング，ばね等の弾性部材を介して係止方向への付勢を付与するようにしてもよい。このとき別部材を回動又はスライド自在に設けて、弾性部材を介して係止方向に付勢させるようにしてもよい。また、逆行阻止手段の一方を係止する方向に重心を位置させて回動自在に設けて、自重により係止するようにしてもよい。
【００４４】
また、逆行阻止手段として、仮止め位置を係止する第一係止手段と固定位置を係止する第二係止手段とを別々の箇所に設けるようにしたが、１箇所に逆行阻止手段を設けるようにすることも可能であり、図１９及び図２０に示すように一方に複数の係合部又は係止部を設けるようにすればよい。図１９は、基板５側に設けられた係止部１１５に屈曲樋１０の仮止め位置で係止する第一係合部１１６ａと固定位置で係止する第二係合部１１６ｂを弾性係止片１１７に設けている。そして、図１９（イ）に示すように屈曲樋１０を摺動することにより、第一係合部１１６ａが係止部１１５に係止し、屈曲樋１０の抜脱方向への逆行を阻止して仮止状態を保持し、さらに、屈曲樋１０を摺動することにより、図１９（ロ）に示すように第二係合部１１６ｂが係止部１１５に係止し位置決め固定される。屈曲樋１０の固定解除は、弾性係止片１１７を付勢に抗して撓ませて第二係合部１１６ｂと係止部１１５との係合を解除して上動させると、第一係合部１１６ａが係止部１１５に衝止して図１９（イ）に示す仮止め状態となり、一気に外れることはない。また、図２０は、基板５側に設ける係止部を仮止め位置で係止する第一係止部１１５ａと位置決め固定させる位置で係止する第二係止部１１５ｂとで構成して下向き階段状に設け、弾性係止片１１７が係止して屈曲樋１０の抜脱方向への移動を阻止するようにしている。そして、図２０（イ）に示すように屈曲樋１０を摺動することにより、弾性係止片１１７の係合部１１６が第一係止部１１５ａに係止し、屈曲樋１０の抜脱方向への逆行を阻止して仮止状態を保持し、さらに、屈曲樋１０を摺動することにより、図２０（ロ）に示すように弾性係止片１１７の係合部１１６が第二係止部１１５ｂに係止し位置決め固定される。屈曲樋１０の固定解除は、弾性係止片１１７を付勢に抗して撓ませて係合部１１６と第二係止部１１５ｂとの係合を解除して上動させると、係合部１１６が第一係止部１１５ａに衝止して図２０（イ）に示す仮止め状態となり、一気に外れることはない。
【００４５】
なお、実施の形態において、裏機構部品の供給樋８として屈曲樋１０の取付構造について説明したが、当然のことながら傾斜樋９の取付構造としてもよい。また、本発明は供給樋８に限ることなく、球払出装置１１等の裏機構部品の取付構造としてもよい。このとき、本発明の裏機構部品の取付構造により取付けた際に、隣接する裏機構部品の取外しが阻止される阻止手段の機能を付加するのが好ましい。
【００４６】
また、実施の形態において基板を機構板５として該機構板５に屈曲樋１０を取付けるようにしたが、例えば屈曲樋１０と球払出装置１１とで払出ユニットを構成して、該払出ユニットのベース板を屈曲樋１０を取付ける基板として上記要領にて屈曲樋１０を取付けるようにしてもよい。また、基板を前面枠２として、球タンク７及び供給樋８等を直接設けるようにしてもよい。
【００４７】
なお、実施の形態において供給樋を１条のものとしたが、複条設けられた供給樋としてもよいのはいうまでもない。
【００４８】
また、前記球払出装置１１は実施の形態に限定されるものではなく、例えば払出回転体７２に替えて先端を嘴状に尖らせて最先のパチンコ球を支持する回動体を球通路７１に進退自在に設けたものであってもよい。この球払出装置は前記回動体の上方に位置して鉛直面内で球荷重により回動する回転規制体を回動自在に設けるのが好ましく、球通路７１の流速を制御すると共に所定間隔をもって回動体に導くようにするのがよい。前記球通路７１は、前記回転規制体の回転を促す方向に屈曲して形成するのが好ましく、前記回動体の直上位置は前記回転規制体が球荷重により巻き込むように送り込むパチンコ球が噛まないように回転方向に僅かながら傾斜して設けるのがよい。
【００４９】
【発明の効果】
このように本発明の供給樋の取付構造では、供給樋を摺動して取付ける係合手段の他に、供給樋の仮止め状態と位置決め固定状態とで係止する係止手段を設けるようにしたので、供給樋を機構板にワンタッチで確実に取付けることができ、しかも無用に外れることがない。また、従来のビス止めのようなビスの閉め忘れや締め加減不良等による不良品発生のおそれはなく、組立コストが軽減され品質も向上するなど有益な効果がある。

2 and 3, the spherical tank 7 is formed in a substantially rectangular box shape having a bottom 20 and four front, rear, left and right side walls 18, 19, 23, and 24, the upper surface of which is open. (The left side wall 23 in the figure), which is gently inclined downward, is located at the downstream end thereof and at the upstream starting end of the inclined gutter 9, and has a large-diameter outlet through which a plurality of pachinko balls can simultaneously flow out. 21 is formed, and a ball-breaking portion 22 is formed on one side of the outlet 21 (on the rear wall 19 side) so as to support the ball center of the pachinko ball. The upper surface of the ball breaking part 22 is gently inclined toward the outlet 21.

Never. Further, the bent gutter 10 is slid so as to press the front wall 30 of the inclined gutter 9 in a state where the second locking means shown in FIG. 17 (b) is locked, and as shown in FIG. The stop groove 113 is locked to the locking rib 112 to reliably prevent the inclined gutter 9 from being pulled out in the removing direction (left direction in the drawing) and to prevent the inclined gutter 9 from bending. The same effect can be obtained by providing a locking rib on the pressing piece 111 and forming a locking groove 113 at the end of the front wall 30 of the inclined gutter 9. In this embodiment, the inclined gutter 9 is detached to the left. However, the inclined gutter 9 may be removed in the forward direction, and when detached upward, the inclination gutter 9 is prevented from moving upward. What is necessary is just to provide a piece. Preferably, the directions of removal of the bent gutter 10 and the inclined gutter 9 are made different, so that a more reliable stopping ability is obtained.

Further, the engaging means is an engaging piece provided on the bent gutter 10 and an engaging receiving part provided on the mechanism plate 5, but the present invention is not limited to the embodiment, and it is possible to provide the engaging means in a reverse manner so as to face each other. The opened engagement receiving portion may be engaged with the upward engagement piece. Further, the engaging means may be a protrusion having a head and a retaining hole, and various methods of sliding engagement are conceivable.
[0043]
Although the first locking means and the second locking means are provided on the supply gutter 8 side as locking pieces with elasticity as the reverse movement preventing means, the locking portion is provided by providing a slit or the like in the mechanism plate 5. You may make it give elasticity. Further, the bias in the locking direction is applied to one of the locking portion and the locked portion to be engaged as the back-stopping device by the elasticity of the material itself. The bias in the locking direction may be applied via an elastic member such as a spring. At this time, another member may be provided rotatably or slidably, and may be urged in the locking direction via an elastic member. Alternatively, the center of gravity may be positioned in the direction in which one of the reverse blocking means is locked so as to be rotatable and locked by its own weight.
[0044]
Further, as the reverse movement preventing means, the first locking means for locking the temporary fixing position and the second locking means for locking the fixed position are provided at different places. It is also possible to provide a plurality of engaging portions or locking portions on one side as shown in FIGS. 19 and 20. FIG. 19 shows an elastic locking of a first engaging portion 116a that locks at a temporary fixing position of the bent gutter 10 to a locking portion 115 provided on the substrate 5 side and a second engaging portion 116b that locks at a fixed position. It is provided on the piece 117. Then, by sliding the bent gutter 10 as shown in FIG. 19A, the first engaging portion 116a is locked by the locking portion 115, and the backward movement of the bent gutter 10 in the removal direction is prevented. As a result, the second engaging portion 116b is locked to the locking portion 115 and fixed in position by sliding the bent gutter 10 as shown in FIG. The fixed release of the bent gutter 10 is performed by bending the elastic locking piece 117 against the urging force to release the engagement between the second engaging portion 116b and the locking portion 115 and moving the elastic locking piece 117 upward. The mating portion 116a collides with the locking portion 115 to be in the temporary fixing state shown in FIG. 19A, and does not come off at a stretch. FIG. 20 shows a downward staircase composed of a first locking portion 115a for locking the locking portion provided on the substrate 5 side at the temporary fixing position and a second locking portion 115b for locking at the position for positioning and fixing. The elastic locking piece 117 is locked to prevent the bent gutter 10 from moving in the pull-out direction. Then, by sliding the bent gutter 10 as shown in FIG. 20A, the engaging portion 116 of the elastic locking piece 117 is locked to the first locking portion 115a, and the withdrawing direction of the bent gutter 10 is removed. 20 (b), the engaging portion 116 of the elastic locking piece 117 is locked by the second locking as shown in FIG. It is locked to the part 115b and fixed in position. To release the fixing of the bent gutter 10, the elastic locking piece 117 is bent against the bias to release the engagement between the engaging portion 116 and the second locking portion 115 b and move upward. The first stop portion 115a comes into contact with the first locking portion 115a to be in a temporary fixing state shown in FIG. 20A, and does not come off at once.

In the embodiment, the mounting structure of the bent gutter 10 as the supply gutter 8 of the back mechanism component has been described, but the mounting structure of the inclined gutter 9 may of course be used. Further, the present invention is not limited to the supply gutter 8, but may be a mounting structure for a back mechanism component such as the ball dispensing device 11. At this time, it is preferable to add a function of blocking means for preventing removal of the adjacent back mechanism component when the back mechanism component is mounted by the mounting structure of the back mechanism component of the present invention.
[0046]
Further, in the embodiment, the bent gutter 10 is attached to the mechanism plate 5 using the substrate as the mechanism plate 5. For example, a payout unit is configured by the bent gutter 10 and the ball payout device 11, and the base of the payout unit is formed. The plate may be used as the substrate on which the bent gutter 10 is mounted. Further, the ball tank 7 and the supply gutter 8 may be directly provided with the substrate as the front frame 2.
[0047]
In the embodiment, the supply gutter is a single supply gutter, but it goes without saying that a supply gutter provided with multiple supply gutters may be used.
[0048]
Further, the ball payout device 11 is not limited to the embodiment. For example, instead of the payout rotating body 72, the tip of the ball is sharpened like a beak and a rotating body that supports the earliest pachinko ball is provided in the ball passage 71. It may be provided so that it can move forward and backward. It is preferable that the ball dispensing device is provided with a rotation regulating body which is positioned above the rotating body and is rotated by a ball load in a vertical plane so as to be freely rotatable. It is good to lead to the moving body. The ball passage 71 is preferably formed to be bent in a direction to promote the rotation of the rotation restricting body, and the position immediately above the rotating body is such that the pachinko ball fed in such that the rotation restricting body is wound by the ball load is not bitten. It is preferable to provide it slightly inclined in the rotation direction.

【The invention's effect】
As described above, in the supply gutter mounting structure of the present invention, in addition to the engagement means for slidingly attaching the supply gutter, the locking means for locking the supply gutter in the temporarily fixed state and the positioning fixed state is provided. Therefore, the supply gutter can be securely attached to the mechanism plate with a single touch, and the supply gutter does not come off unnecessarily. Further, there is no danger of defective products due to forgetting to close screws or improper tightening or tightening, unlike conventional screwing, and has a beneficial effect such as a reduction in assembly cost and an improvement in quality.
