Description

【０００１】
【発明の属する技術分野】
本発明は、遊技盤に入賞玉集合カバーを取り付けるための取付構造に関するものである。
【０００２】
【従来の技術】
この種の取付構造としては、実公平７−４５２５８号公報に開示されたものが知られている。このものでは、遊技盤の裏面の４隅に取付部材が配され、各取付部材に備えられた係止片によって入賞玉集合カバーを取り付けるようにしている。これに対応して、入賞玉集合カバーの４隅にはそれぞれ嵌合凹部が切り欠き形成されている。したがって、入賞玉集合カバーを遊技盤の裏面に取り付けるためには、各取付部材をそれぞれ嵌合凹部に嵌め合わせながら入賞玉集合カバーを遊技盤の裏面に重ね合わせ、さらに取付部材の係止片を操作して入賞玉集合カバーに係止させればよい。
【０００３】
なお、遊技盤の裏面には遊技領域に設けられた各入賞玉受入装置に対応してレール状の案内部材が配されており、入賞玉集合カバーはこれら案内部材の蓋をして各入賞玉受入装置に入賞した入賞玉が案内部材に誘導されて入賞玉集合樋へ集められるようにしている。
【０００４】
【発明が解決しようとする課題】
上記の取付構造による場合、入賞玉集合カバーを取り付ける前には、案内部材と取付部材を装着しておかねばならないのであるが、これらは別部品として設定されているため個別の取り付け作業を行い、個別に各々の位置決めをしておかねばならない。特に、取付部材は４カ所においてそれぞれ正しく位置決めされておらねばならないことから、作業が煩雑化し作業性をより低下させる原因にもなる。さらに、取付部材と案内部材とを個別に必要とする構造では、部品管理の面からも不利である。
【０００５】
また、係止片には、入賞玉集合カバーと遊技盤が外れる方向に対する解除規制手段が設けられていないため、係止操作後にこの係合が外れてしまう虞もあった。
本発明は、上記事情に鑑みてなされたものであり、その目的は、遊技盤の裏面に入賞玉集合カバーを簡単に取り付けることができると共に、不用意に外れることがない入賞玉集合カバーの取付構造を提供するところにある。
【０００６】
【課題を解決するための手段】
上記目的を達成するために、請求項１の発明に係る入賞玉集合カバーの取付構造は、遊技盤の裏面に、少なくとも二カ所以上の係合受部が一体に形成された係合受部材と、入賞玉を入賞玉集合樋へ誘導するための案内路が備えられた案内路形成部材が取り付けられるとともに、この案内路形成部材に入賞玉集合カバーを重ね合わせた状態で前記係合受部材に対応して配された係合部材を、前記係合受部材に係合させることによって取り付けられるものであって、前記係合部材は、前記係合受部材に対して非係合状態である解除位置と、係合受部材に対して係合するロック位置との間でスライド変位可能となっているとともに操作部及び弾性突片を備え、前記係合部材が前記ロック位置にあるとき前記弾性突片が前記入賞玉集合カバーに設けた当接部に係合して前記解除位置への戻りが規制され、前記係合部材が前記解除位置にあるとき前記弾性突片が前記入賞玉集合カバーに設けた係止爪用凹部に係合することを特徴とする。
【０００７】
請求項２の発明は、請求項１に記載のものであって、前記係合部材には更に保持凹部が形成され、前記係合部材が前記ロック位置にあるときに前記入賞玉集合カバーに設けた保持突部と前記保持凹部とが係合することを特徴とする。
【０００８】
【発明の作用および効果】
請求項１の発明によれば、遊技盤の裏面に係合受部材と案内路形成部材を装着する。そして、その後に案内路形成部材に対して入賞玉集合カバーを重ね合わせ、解除位置にある各係合部材をロック位置にまで変位させて対応する係合受部材にそれぞれ係合させれば、入賞玉集合カバーの取り付けが完了する。ロック位置で係合部材は入賞玉集合カバーの当接部に係合することで解除位置への戻りが規制されて偶発的な係合解除が防止される。また、係合部材が解除位置にあるときには、弾性突片が入賞玉集合カバーの係止爪用凹部に係合することでその位置に保持される。
【０００９】
この場合において、係合受部材が案内路形成部材に一体に設けられている場合には、案内路形成部材についてのみ遊技盤への位置決めを行えば、自動的に係合受部材に対する位置決めもなされる。したがって、本発明では従来の場合のように、これらを個別に位置決めして取り付ける煩わしさから解放され、また部品点数も減少できるため、コストの低減と部品管理の容易化が図れる。
一方、係合受部材と案内路形成部材とが別体で形成されている場合には、遊技盤が新しく開発された場合にも、案内路形成部材のみをその新しい遊技盤に対応すれば足りる。このため、金型の形成が少なくてよい。
【００１０】
また、請求項２の発明によれば、係合部材がロック位置にあるときに、その保持凹部と入賞玉集合カバーの保持突部とが係合して二カ所で係合解除が規制されるため、偶発的な係合解除をいっそう確実に防止できる。
【００１１】
【発明の実施の形態】
＜第１実施形態＞
次に、本発明の入賞玉集合カバーの取付構造を具体化した第１実施形態について図１〜図１５を参照して説明する。
【００１２】
図１４には、パチンコ機の正面図を示した。額縁状に形成されたパチンコ機の前面枠１１には、金枠１２が嵌め込まれており、その金枠１２の開口のうち下側開口部分は前面板１３によって塞がれている。この前面板１３には、打球を貯留して打球発射装置（図示せず）に打球を供給する上受け皿１４が取付られている。また、金枠１２の開口のうち、上側開口部分には窓枠１５が嵌め込まれ、そこには透明な板硝子１６が嵌め込まれている。さらに、前面枠１１のうち、前面板１３の下方部分には賞球を貯留する下受け皿１７及び打球発射装置を操作するハンドル１８が設けられている。前面枠１１の裏面側には、図示しない遊技盤取付枠が設けられており、そこには図１に示す遊技盤１９が装着されるようになっている。このようにして、窓枠１５内に遊技盤１９が配置される。また、この遊技盤１９の前面には、遊技領域が形成されており、そこには、各種の入賞玉受入装置や、可変表示装置、装飾ランプ等が配されている。
【００１３】
次に、図１に示すように遊技盤１９の裏面には、案内路形成部材２０が取り付けられた後、その案内路形成部材２０を覆うように入賞玉集合カバー２１が取り付けられる。以下、順に各々の構成について詳細に説明する。
遊技盤１９には、ほぼ中央に開口部１９Ａが形成されており、この開口部１９Ａを介して遊技領域に取り付けられている可変表示装置等の後端部が、裏面側に突出するようになっている。また、この開口部１９Ａを取り囲む所定の位置には計４個の凹部１９Ｂが形成されている。この凹部１９Ｂは、ルータ加工によって形成されるものであり、略長方形状にされる。さらに、この遊技盤１９の下端部中央部分には、アウト玉を排出するアウト玉出口１９Ｃが設けられ、その他には遊技領域の複数箇所に配された各入賞玉受入装置に対応して図示しない入賞玉排出口等が形成されている。
【００１４】
案内路形成部材２０は、ほぼ方形状をなす樹脂製の板であり、その中央部には遊技盤１９の開口部１９Ａに対応した位置に、これよりもやや大きい方形状をなす開口部２０Ａが形成されている。また、上部には、中継基板取付台３７が延出形成されており、そこには図１５に示すように中継基板３８が取り付けられるようになっている。この中継基板３８には、図示しない機構板の裏面側へ突出する接続端子３９及び遊技領域に配される各種装飾ランプや可変表示装置等への配線を一旦中継するための中継コネクタ４０等が配設されている。さらに、この案内路形成部材２０には、遊技領域に配される各入賞玉受入装置に対応して複数の案内路２８が裏面側（遊技盤１９の裏面に整合する側とは反対側）に膨出するように形成されている。各案内路２８は遊技盤１９と対向する側に開口する樋状に形成されて、図示しない入賞玉排出口に対して整合可能となっており、各入賞玉受入装置に入賞した入賞玉を案内路２８に沿って下方へ案内することができるようにしている。また、案内路２８の下端は下方へ開口し、ここから案内路２８内を通ってきた入賞玉を落下させ、さらに、図示しない入賞玉集合樋へ落とし込ませて集合させることができるようになっている。そして、入賞玉集合樋に集められた入賞玉は入賞玉処理機構において一個宛処理され、所定の個数の賞品玉が遊技者に払い出されるようになっている。
【００１５】
また、案内路形成部材２０には、その４隅部分、即ち遊技盤１９の凹部１９Ｂに対応する位置に係合受部材２２が一体に形成されている。この各係合受部材２２は、図５に示すように、案内路形成部材２０の裏面から直角に立ち上がり形成されるとともに、その内部には相互に対向する側の面（上下に位置する係合受部材２２同士が対向する側の面）に開口を有する係止片結合室２３が形成されている。そして、この係止片結合室２３内の天井面の奥部には、保持突部２４が形成されている。また、係合受部材２２の基端部２２Ａは、上記凹部１９Ｂの形状に対応して枠状に張り出して、表面側（遊技盤１９の裏面に整合する面）に僅かに突出している。そして、案内路形成部材２０を遊技盤１９の裏面に取り付ける際には、この各基端部２２Ａを遊技盤１９の凹部１９Ｂに嵌め込むことにより案内路形成部材２０の位置決めがされるようになっている。各係合受部材２２の上下両側方には、遊技盤１９と案内路形成部材２０を締め付けるためのねじ２６を通す取付孔２５が形成されている。
【００１６】
入賞玉集合カバー２１は、樹脂により案内路形成部材２０より僅かに大きな方形状をなして形成されており、案内路形成部材２０を裏面側から覆うことができるようにされている。この入賞玉集合カバー２１にも案内路形成部材２０の開口部２０Ａと同様に、遊技盤１９の開口部１９Ａに対応した位置に開口部２１Ａが形成されている。この開口部２１Ａは、案内路形成部材２０の開口部２０Ａとほぼ同じ大きさに形成され、入賞玉集合カバー２１を案内路形成部材２０に取り付けたときに開口部２０Ａと開口部２１Ａが整合するようになっている。また、入賞玉集合カバー２１の左右両縁部及び上縁部の一部（図６中、左右両縁部及び上縁部の一部）は僅かに表面側に立ち上がり形成されており、入賞玉集合カバー２１が遊技盤１９に取り付けられると、遊技盤１９との間に案内路形成部材２０を覆うことができる空間を形成するようになっている。なお、入賞玉集合カバー２１の下縁部は、左右両端部分が上記左右両縁部に連なって立ち上り形成されているが、その他の部分はそのようには形成されていない。このため、入賞玉集合カバー２１を遊技盤１９に取り付けた際には、下面に遊技盤１９との間に開口を形成して案内路２８から落下する入賞玉がこの開口を介して入賞玉集合樋に集められるようになっている。
【００１７】
さらに、入賞玉集合カバー２１の４隅部分、即ち上記案内路形成部材２０に設けられた各係合受部材２２に対応する位置には、図６に示すように、それぞれロック機構２９が構成されている。このロック機構２９は、係止片収容凹部３０内に設けられており、これらは図２及び図７に示すように、入賞玉集合カバー２１の表面側から側面にかけて長細く凹み形成されている。この係止片収容凹部３０の一方の端部（上側の係止片収容凹部では上端部、下側の係止片収容凹部では下端部）には挿通孔３０Ａが形成されており、入賞玉集合カバー２１を遊技盤１９の裏面に組付けると、案内路形成部材２０の係合受部材２２がここから係止片収容凹部３０内に突出するようになっている。
【００１８】
また、係止片収容凹部３０において上記した挿通孔３０Ａとは反対側の端部には、段差状に形成され一端側（係合受部材２２が突出する側）を開口する嵌合部３１が設けられている。さらに、係止片収容凹部３０の底面には、嵌合部３１の開口縁部から挿通孔３０Ａにかけてガイド溝３２が形成されている。そして、このガイド溝３２には、後述する係止片３３が、弾性突片４１を嵌合部３１に嵌め込んだ状態で係合する。これにより、係止片３３はガイド溝３２に沿って上下方向にスライド可能とされるとともに、奥側にスライドした際には係止片３３の三角溝４２が設けられた部分が挿通孔３０Ａから突出する係合受部材２２の係止片結合室２３内に挿入される。
【００１９】
係止片３３は図３に示すように、合成樹脂材により一体に形成されており、ガイド溝３２内を上下にスライドして案内路形成部材２０の係合受部材２２と係合するロック位置（図１１及び図１３に示す位置）と、入賞玉集合カバー２１の嵌合部３１内に収容されて係合受部材２２とは非係合状態にある解除位置（図９，１０，１２に示す位置）との間を変位することができる。
なお、以下の説明では断り書きの無い限り、図２および図３の位置（入賞玉集合カバー２１を後ろ側から見たときに、左下に該当する。）を参照しつつ説明する。
【００２０】
係止片３３の中央部のやや下方よりの位置には、操作片３６が突出している。これは係止片３３のスライド操作のためのものであり、何れも外側を向いた状態で組み付けられる。また、係止片３３の一方の端部からは三角溝４２が切り欠き形成されており、その三角溝４２によって形成された一対の脚状部の側面側には、各々に保持凹部３３Ｂが凹み形成されている。三角溝４２が形成されているため、保持凹部３３Ｂは、係止片結合室２３内の保持突部２４に対して弾性的に係合可能である。
【００２１】
一方、操作片３６を境にして三角溝４２とは反対側には、この操作片３６と同じ側に突出する弾性突片４１（本発明の解除規制部に相当する）が撓み変形可能に突設されている。そして、その先端には係止爪４１Ａが突設されており、嵌合部３１内の係止爪用凹部４３に係合可能である。これによって、係止片３３が解除位置に保持される。また、弾性突片４１の先端部分は、後述するロック位置において当接端面４４（嵌合部３１を形成する壁面のうち、係止爪用凹部４３が形成された壁面の先端部分）とほぼ同じ高さに位置する。
【００２２】
係止片３３において上記した保持凹部３３Ｂとは反対側の端部にも同様にして左右一対の保持凹部３３Ａが凹み形成されている。両保持凹部３３Ａは嵌合部３１内に形成された保持突部３１Ａに係合して、係止片３３を解除位置に保持するようになっている。
また、図６中、ガイド溝３２の挿通孔３０Ａ寄りの部分には、半円状に凹み形成されたガイド片嵌合凹部３４が設けられており、ここに円形のガイド片３５をその一部をガイド溝３２に突出させた状態でねじ止めすることができるようになっている。これにより、図８に示すように、係止片３３の一部が後方（図８中、上方）から押さえられ、係止片３３がガイド溝３２から外れることなく円滑にスライド可能とされる。
【００２３】
次に、入賞玉集合カバー２１の取付作業について述べる。まず、案内路形成部材２０を遊技盤１９の裏面に取り付ける。それには、案内路形成部材２０を遊技盤１９の裏面に重ね合わせるとともに、各係合受部材２２の基端部２２Ａをそれぞれ遊技盤１９の凹部１９Ｂに嵌め合わせるようにして案内路形成部材２０を位置決めする。そして、この状態のまま案内路形成部材２０の各取付孔２５にねじ２６を挿入し、これらを遊技盤１９に締め付けて案内路形成部材２０を遊技盤１９の裏面に固定する（図９参照）。
【００２４】
一方、入賞玉集合カバー２１の四つのガイド溝３２内に、係止片３３の弾性突片４１を撓ませながら挿入して、解除位置に待機させておく。そして、案内路形成部材２０を覆うように遊技盤１９の裏面に入賞玉集合カバー２１を重ね合わせる。さらに、入賞玉集合カバー２１の各挿通孔３０Ａに案内路形成部材２０側の各係合受部材２２を挿通させる。これにより、入賞玉集合カバー２１の各係止片収容凹部３０内には、それぞれ係合受部材２２が突出することになる（図１０，図１２を参照）。ここから、各操作片３６をそれぞれ図１０中矢印方向に操作する。すると、係止片３３はロック位置にスライドするから、係止片３３の一端部が係合受部材２２の係止片結合室２３内に挿入される。このとき、弾性突片４１は復帰変形して、当接端面４４の直近に位置する（図１３を参照）。さらに、係止片３３の保持凹部３３Ｂが係止片結合室２３内の保持突部２４に係合するため、係止片３３はロック位置に保持される。これにより、係止片３３と係合受部材２２とは結合状態（図１１，図１３に示す状態）とされ、もって入賞玉集合カバー２１は遊技盤１９の裏面に保持される。このとき、弾性突片４１の先端は、当接端面４４と同じ高さに位置しているため、係止片３３に対して偶発的に解除位置に移動させようとする力が働いても、ロック位置の係合が解除されないようになっている。
【００２５】
次いで、入賞玉集合カバー２１を取り外す場合について述べる。上記、結合状態において、弾性突片４１を押圧して撓ませつつ、操作片３６をそれぞれ図１０で示す矢印方向とは反対方向にスライド操作する。すると、係止片３３は係合受部材２２の係止片結合室２３から抜き出されて解除位置に移行し、このとき係止片３３の保持凹部３３Ａが嵌合部３１内の保持突部３１Ａに係合して、その状態に保持される。これにより、係止片３３と係合受部材２２との結合状態は解除されるから、入賞玉集合カバー２１を遊技盤１９から取り外すことができる。
【００２６】
このように本実施形態によれば、入賞玉集合カバー２１を遊技盤１９の裏面に取り付けるためには、まず遊技盤１９の裏面に案内路形成部材２０を取り付け、その後この案内路形成部材２０に一体に設けられた係合受部材２２に入賞玉集合カバー２１の係止片３３を結合させるだけでよい。
即ち、入賞玉集合カバー２１を取り付けるための一連の作業において、係合受部材２２単独の組付作業は省略される。従って、本実施形態では、従来のように係合受部材２２を個別に組み付ける必要がないからその位置決め作業等が不要とされ、ひいては、入賞玉集合カバー２１の取付作業が容易とされる。
【００２７】
また、このとき保持凹部３３Ｂと保持突部２４の係合に加えて、係止片３３の弾性突片４１が当接端面４４に当接する位置にあるという二つの解除規制部がある。このため、偶発的にロック位置から解除位置に移動するのを妨げられる。なお、この実施形態では、弾性突片４１と当接端面４４との係合力は、保持凹部３３Ｂと保持突部２４との係合力よりも強く設定されている。
さらに、係合受部材２２と案内路形成部材２０とが一体であるから、部品点数を少なくすることができ、もって型代等の経済的負担や部品管理等の管理面での負担を軽減することができる。
【００２８】
しかも、本実施形態では、案内路形成部材２０に中継基板取付台３７も一体に形成されているから、この中継基板取付台３７に対する個別の位置決め及び取付作業が不要とされるなど、一層、作業面・経済面等における負担を軽減することができる。
加えて、各入賞玉受入装置に対応する複数の案内路２８は案内路形成部材２０に形成されているから、遊技盤１９が新しく開発された場合には、この案内路形成部材２０のみ新しい遊技盤１９に対応させれば足りる。
【００２９】
＜第２実施形態＞
次に、本発明の第２実施形態について、図１６〜図２５を参照しつつ説明する。
なお、本実施形態と第１実施形態とにおいて、同様の構成には同一符号を付して説明の一部を省略する。
本実施形態においては、係合受部材２２を上下一対に配置したカバー係止部材５１、案内路形成部材５０及び中継基板取付台５２は、それぞれ別体として形成されており、各々遊技盤１９の裏面に独立して取り付けられる。すなわち、図１６に示すように遊技盤１９の裏面には、案内路形成部材５０、左右に一対のカバー係止部材５１、及び中継基板取付台５２が取り付けられた後、これらの部材を覆うように入賞玉集合カバー５３が取り付けられる。
【００３０】
案内路形成部材５０は樹脂により成形されており、遊技盤１９の開口部１９Ａの左縁と下縁の外方に沿う部分のみが形成されている。この案内路形成部材５０には、遊技領域に配される各入賞玉受入装置に対応して複数の案内路５４が裏面側に膨出するように形成されている。各案内路５４は、第１実施形態における案内路２８と同様の作用効果を以て形成される。
また、案内路形成部材５０の周端部分には、所定の間隔をもって取付孔５０Ａが設けられており、案内路形成部材５０を遊技盤１９に取り付ける際に、ねじ２６が嵌め込まれる。
【００３１】
次に、カバー係止部材５１は左右一対に同じものが配されており、遊技盤１９の上下に位置する凹部１９Ｂ，１９Ｂに対応して係合受部材２２が形成されている。また、カバー係止部材５１の中間部分には、係合凸部５５が設けられている。この係合凸部５５は、入賞玉集合カバー５３が組み付けられたときに、入賞玉集合カバー５３側の係合凹部５６に凹凸嵌合して、入賞玉集合カバー５３と、カバー係止部材５１の位置合わせを容易にすると共に、両部材が組み付いた後にはがたつきをなくすように作用する。
【００３２】
中継基板取付台５２は、図示しない中継基板の形状に合わせて形成されている。第１実施形態において説明したように、中継基板には遊技領域等に配される装飾ランプ等への配線を中継するためのコネクタ等が配置される。中継基板取付台５２の周囲には、所定の位置に取付孔５２Ａが設けられており、ここにねじ２６を嵌め付けることにより、遊技盤１９に中継基板取付台５２を固定する。
【００３３】
入賞玉集合カバー５３は、合成樹脂により方形状をなして形成されており、案内路形成部材５０及びカバー係止部材５１を裏面側から覆うことができるようにされている。この入賞玉集合カバー５３には、遊技盤１９の開口部１９Ａに対応した位置に開口部１９Ａよりも大きな開口部５３Ａが形成されており、入賞玉集合カバー５３を取り付けたときに両開口部１９Ａ，５３Ａが整合するようになっている。
また、入賞玉集合カバー５３の左右両縁部及び上縁部の一部（図１９中、左右両縁部及び上縁部の一部）は僅かに表面側に立ち上がり形成されており、入賞玉集合カバー５３が遊技盤１９に取り付けられたときに、遊技盤１９との間に案内路形成部材５０及びカバー係止部材５１を覆うことができる空間を形成するようになっている。一方、入賞玉集合カバー５３の下縁部は、左右両端部分が上記左右両縁部に連なって立ち上り形成されているが、その他の部分はそのようには形成されていない。このため、入賞玉集合カバー５３を遊技盤１９に取り付けた際には、下面に遊技盤１９との間に開口を形成して案内路５４から落下する入賞玉がこの開口を介して入賞玉集合樋に集められるようになっている。
【００３４】
さらに、入賞玉集合カバー５３の４隅部分、即ち上記カバー係止部材５１に設けられた係合受部材２２が対応する位置には、図１９又は図２０に示すように、それぞれロック機構５７が構成されている。このロック機構５７は、係止片収容凹部３０内に設けられており、入賞玉集合カバー５３の表面側から側面にかけて長細く凹み形成されている。この係止片収容凹部３０の一方の端部には挿通孔３０Ａが形成されており、入賞玉集合カバー５３を遊技盤１９の裏面に組付けると、係合受部材２２がここから係止片収容凹部３０内に突出する。
また、ガイド溝３２の挿通孔３０Ａ寄りの部分には、係止片保持突部５９が突設されている。この係止片保持突部５９は、係止片５８がガイド溝３２に取り付けられたときに、その側面部分に当接するようになっている。このため、係止片５８はガイド溝３２から外れることなく円滑にスライド可能とされる。
【００３５】
上下のロック機構５７の中間位置は、係合凹部５６とされている。この係合凹部５６は、入賞玉集合カバー５３がカバー係止部材５１に組み付けられたときに、前述した係合突部５５に係合可能になっている。
さらに、入賞玉集合カバー５３の下端部分には、案内路５４の出口５４Ａに対応した位置に後面側に突設する３個の誘導壁６０が設けられている。各誘導壁６０の内側は入賞玉集合カバー５３の前面から下面へと連結する通路６３とされており、案内路５４下端部分の出口５４Ａに導かれた入賞玉がさらに下方に位置する図示しない誘導樋に誘導される。このように各案内路５４に応じて誘導壁６０を設けることにより、遊戯台前面にある入賞玉受入装置の位置に応じて賞品玉の個数を例えば７個や１５個と変化させることが容易となる。
誘導壁６０のうち、中央に設けられたものの周囲には所定の領域にわたってスリット６１が縦横に形成されており、中央に位置する誘導壁６０周りの所定領域を容易に切り落とすことができるようになっている。これにより、必要に応じて入賞玉集合カバー５３の下端部中央部分に大きな開口を形成することができる。この開口は、遊技盤１９の種類に応じて設けられる大入賞口、いわゆるアタッカが取り付けられた場合に、遊技盤１９の裏面に突出する図示しないアタッカの後端部分に合わせたアタッカ突出口となる。
【００３６】
なお、両側部に形成された誘導壁６０間には各下端縁同士を連ねる位置にリブ６２が突出形成されている。このリブ６２と中央の誘導壁６０とは分離溝６４を隔てて構成されているため、中央の誘導壁６０を切り落とした後でも、両側部の誘導壁６０の下端縁同士はリブ６２によって連結されている。このため、リブ６２は、入賞玉集合カバー５３の下辺を補強する役割をしており、入賞玉集合カバー５３の下端部を撓み変形し難くしている。
次に、係止片５８の説明を行うが、特に断り書きの無い限り、図２０の位置（入賞玉集合カバー５３を後ろ側から見たときに、左下に該当する。）を参照するものとする。
係止片５８は図２１に示すように、合成樹脂材により一体に形成されており、ガイド溝３２内を上下にスライドして、カバー係止部材５１と係合するロック位置（図２３に示す位置）と、入賞玉集合カバー５３の嵌合部３１内に収容されてカバー係止部材５１とは係合してない解除位置（図２４に示す位置）との間を変位することができる。
【００３７】
本実施形態の係止片５８と、第１実施形態の係止片３３との構成の相違は、保持凹部３３Ａの有無のみである。すなわち、本実施形態の係止片５８では、保持凹部３３Ａが設けられていないため、係止片５８が解除位置にある場合には、弾性突片４１前端部分の係止爪４１Ａのみで嵌合部３１内に係止している。
次に、入賞玉集合カバー５３の取付作業について述べる。まず、案内路形成部材５０、一対のカバー係止部材５１、及び中継基板取付台５２を遊技盤１９の裏面に取り付ける。
【００３８】
案内路形成部材５０を遊技盤１９の裏面の所定の位置に合わせて、取付孔５０Ａにねじ２６を挿入する。同様にして、中継基板取付台５２を遊技盤１９の所定の位置に合わせつつ、ねじ２６で固定する。一方、各カバー係止部材５１については、基端部２２Ａをそれぞれ遊技盤１９の凹部１９Ｂに嵌め合わせるようにして位置決めを行い、各取付孔２５にねじ２６を挿入し、これらを遊技盤１９に締め付けてカバー係止部材５１を遊技盤１９の裏面に固定する。
【００３９】
一方、入賞玉集合カバー５３の四つのガイド溝３２内に、係止片５８の弾性突片４１を撓ませながら挿入して、解除位置に待機させておく。このとき、係止片保持突部５９が、係止片５８の側面を押さえるようにして保持しているため、係止片５８はガイド溝３２から、容易に外れないようになっている。
入賞玉集合カバー５３を遊技盤１９に対して組み付ける手順は、第１実施形態と同様であるため省略する。
【００４０】

In this case, mounting members are arranged at the four corners of the back of the game board, and the winning ball collective cover is mounted by the locking pieces provided on each mounting member. Correspondingly, fitting recesses are cut out at the four corners of the winning ball collective cover. Therefore, in order to attach the winning ball collective cover to the back surface of the game board, the winning ball collective cover is overlapped on the back surface of the game board while fitting each mounting member into the fitting recess, and further the locking piece of the mounting member is attached. It only has to be operated and locked to the winning ball collecting cover.
[0003]
A rail-shaped guide member is arranged on the back side of the game board corresponding to each winning ball receiving device provided in the gaming area, and the winning ball collective cover covers each of the winning balls by covering these guiding members. The winning balls that have won the receiving device are guided by the guide member and collected in the winning ball collecting basket.
[0004]
[Problems to be solved by the invention]
In the case of the above mounting structure, the guide member and the mounting member must be mounted before mounting the winning ball collective cover, but these are set as separate parts, so individual mounting work is performed, Each positioning must be done individually. In particular, since the mounting members must be correctly positioned at four locations, the work becomes complicated and the workability is further reduced. Furthermore, a structure that requires an attachment member and a guide member separately is disadvantageous from the viewpoint of component management.
[0005]
Further, since the locking piece is not provided with a release restricting means for the direction in which the winning ball collecting cover and the game board are detached, there is a possibility that the engagement is released after the locking operation.
The present invention has been made in view of the above circumstances, and an object of the present invention is to easily attach the winning ball collective cover to the back surface of the game board and to attach the winning ball collective cover that does not come off carelessly. It is in providing structure.
[0006]
[Means for Solving the Problems]
 In order to achieve the above object, the winning ball collective cover mounting structure according to the invention of claim 1 includes an engagement receiving member in which at least two engagement receiving portions are integrally formed on the back surface of the game board. A guide path forming member provided with a guide path for guiding the winning ball to the winning ball assembly cage is attached, and the engagement receiving member is attached to the guide path forming member in a state where the winning ball assembly cover is overlapped. It is attached by engaging a correspondingly arranged engaging member with the engaging receiving member, and the engaging member is in a non-engaged state with respect to the engaging receiving member Between the position and the lock position engaged with the engagement receiving member.slideIt is possible to displaceAn operation portion and an elastic projection piece, and when the engagement member is in the locked position, the elastic projection piece engages with a contact portion provided on the winning ball collective cover to restrict the return to the release position. When the engaging member is in the release position, the elastic protruding piece engages with a locking claw recess provided in the winning ball collecting cover.It is characterized by that.
[0007]
 The invention according to claim 2 is the one according to claim 1,The engaging member is further formed with a holding recess, and when the engaging member is in the locked position, the holding protrusion provided on the winning ball collecting cover and the holding recess engage.It is characterized by that.
[0008]
Operation and effect of the invention
 According to the first aspect of the present invention, the engagement receiving member and the guide path forming member are mounted on the back surface of the game board. Then, the winning ball collective cover is overlaid on the guide path forming member, and each engagement member at the release position is displaced to the lock position and engaged with the corresponding engagement receiving member, respectively. Installation of the ball assembly cover is completed.By engaging the engagement member with the abutting portion of the winning ball collecting cover at the lock position, the return to the release position is restricted and accidental release of the engagement is prevented. Further, when the engaging member is in the release position, the elastic protruding piece is held in that position by engaging with the engaging claw recess of the winning ball collecting cover.
[0009]
In this case, when the engagement receiving member is provided integrally with the guide path forming member, if only the guide path forming member is positioned on the game board, the engagement receiving member is automatically positioned. The Accordingly, in the present invention, unlike the conventional case, it is freed from the trouble of individually positioning and attaching them, and the number of parts can be reduced, so that the cost can be reduced and the parts management can be facilitated.
On the other hand, when the engagement receiving member and the guide path forming member are formed separately, even when a new game board is newly developed, it is sufficient that only the guide path forming member corresponds to the new game board. . For this reason, there is little formation of a metal mold | die.
[0010]
 According to the invention of claim 2, when the engaging member is in the locked position, the holding recess and the holding projection of the winning ball collective cover are engaged, and the disengagement is restricted at two places. Therefore, accidental disengagement can be prevented more reliably.

The guide path forming member 20 is a resin plate having a substantially square shape, and an opening portion 20A having a slightly larger square shape is formed at a position corresponding to the opening portion 19A of the game board 19 at the center thereof. Is formed. In addition, a relay board mounting base 37 is formed on the upper part, and a relay board 38 is attached thereto as shown in FIG. The relay board 38 is provided with a connection terminal 39 projecting to the back side of the mechanism plate (not shown), a relay connector 40 for temporarily relaying wiring to various decorative lamps, variable display devices, etc. arranged in the game area. It is installed. Further, the guide path forming member 20 has a plurality of guide paths 28 on the back side (the side opposite to the side aligned with the back side of the game board 19) corresponding to each winning ball receiving device arranged in the game area. It is formed to bulge. Each guide path 28 is formed in a bowl shape that opens to the side facing the game board 19 and can be aligned with a winning ball outlet that is not shown, and guides the winning ball that has won the winning ball receiving device. It is possible to guide downward along the path 28. In addition, the lower end of the guide path 28 opens downward, and the prize balls that have passed through the guide path 28 can be dropped from there, and can further be dropped into a prize ball collecting cage (not shown) to be assembled. ing. The winning balls collected in the winning ball set are processed by one in the winning ball processing mechanism, and a predetermined number of prize balls are paid out to the player.
[0015]
Further, the guide path forming member 20 is integrally formed with engagement receiving members 22 at the four corners thereof, that is, at positions corresponding to the recesses 19B of the game board 19. As shown in FIG. 5, each of the engagement receiving members 22 is formed at a right angle from the back surface of the guide path forming member 20, and inside thereof, the surfaces facing each other (the engagements positioned above and below). A locking piece coupling chamber 23 having an opening is formed on the surface on the side where the receiving members 22 face each other. A holding projection 24 is formed at the back of the ceiling surface in the engagement piece coupling chamber 23. Further, the base end portion 22A of the engagement receiving member 22 protrudes into a frame shape corresponding to the shape of the concave portion 19B and slightly protrudes to the front surface side (a surface that matches the back surface of the game board 19). When the guide path forming member 20 is attached to the back surface of the game board 19, the guide path forming member 20 is positioned by fitting each base end portion 22 A into the recess 19 B of the game board 19. ing. Mounting holes 25 through which screws 26 for fastening the game board 19 and the guide path forming member 20 are formed are formed on both upper and lower sides of each engagement receiving member 22.
[0016]
The winning ball collective cover 21 is formed of resin so as to have a slightly larger square shape than the guide path forming member 20, and the guide path forming member 20 can be covered from the back side. Similarly to the opening 20 A of the guide path forming member 20, the winning ball collective cover 21 has an opening 21 A at a position corresponding to the opening 19 A of the game board 19. The opening 21A is formed to be approximately the same size as the opening 20A of the guide path forming member 20, and the opening 20A and the opening 21A are aligned when the winning ball collecting cover 21 is attached to the guide path forming member 20. It is like that. Further, the left and right edge portions and a part of the upper edge portion (in FIG. 6, the left and right edge portions and a part of the upper edge portion) of the winning ball collective cover 21 are slightly formed on the surface side. When the collective cover 21 is attached to the game board 19, a space capable of covering the guide path forming member 20 is formed with the game board 19. The lower edge portion of the winning ball collective cover 21 is formed so that both left and right end portions are connected to the left and right edge portions, but the other portions are not formed as such. For this reason, when the winning ball collective cover 21 is attached to the game board 19, the winning ball which forms an opening between the game board 19 on the lower surface and falls from the guide path 28 passes through this opening. It can be collected in the cage.
[0017]
Further, as shown in FIG. 6, lock mechanisms 29 are formed at the four corners of the winning ball collective cover 21, that is, at positions corresponding to the respective engagement receiving members 22 provided on the guide path forming member 20. ing. The lock mechanism 29 is provided in the locking piece accommodating recess 30, and as shown in FIGS. 2 and 7, the lock mechanism 29 is formed in a long and narrow recess from the surface side to the side surface of the winning ball collective cover 21. An insertion hole 30A is formed in one end of the locking piece receiving recess 30 (the upper end portion in the upper locking piece receiving recess and the lower end portion in the lower locking piece receiving recess). When the cover 21 is assembled to the back surface of the game board 19, the engagement receiving member 22 of the guide path forming member 20 protrudes from here into the locking piece housing recess 30.
[0018]
Further, a fitting portion 31 that is formed in a step shape and opens at one end side (side from which the engagement receiving member 22 protrudes) is formed at the end portion of the locking piece housing recess 30 opposite to the above-described insertion hole 30A. Is provided. Further, a guide groove 32 is formed on the bottom surface of the locking piece housing recess 30 from the opening edge of the fitting portion 31 to the insertion hole 30A. Then, a locking piece 33 described later is engaged with the guide groove 32 in a state where the elastic protruding piece 41 is fitted into the fitting portion 31. As a result, the locking piece 33 can be slid in the vertical direction along the guide groove 32, and when the locking piece 33 is slid to the back side, the portion of the locking piece 33 provided with the triangular groove 42 extends from the insertion hole 30A. The protruding engagement receiving member 22 is inserted into the locking piece coupling chamber 23.
[0019]
As shown in FIG. 3, the locking piece 33 is integrally formed of a synthetic resin material and slides up and down in the guide groove 32 to engage with the engagement receiving member 22 of the guide path forming member 20. (The position shown in FIGS. 11 and 13) and the release position (in FIGS. 9, 10 and 12) which is accommodated in the fitting portion 31 of the winning ball collective cover 21 and is not engaged with the engagement receiving member 22. (Position shown) can be displaced.
In the following description, unless otherwise noted, the description will be made with reference to the positions shown in FIGS. 2 and 3 (corresponding to the lower left when the winning ball collecting cover 21 is viewed from the rear side).
[0020]
An operation piece 36 projects at a position slightly below the center of the locking piece 33. This is for the sliding operation of the locking piece 33, and each is assembled in a state of facing outward. Further, a triangular groove 42 is cut out from one end of the locking piece 33, and holding recesses 33 B are recessed in the side surfaces of the pair of leg portions formed by the triangular groove 42. Is formed. Since the triangular groove 42 is formed, the holding recess 33 B can be elastically engaged with the holding protrusion 24 in the locking piece coupling chamber 23.
[0021]
On the other hand, on the side opposite to the triangular groove 42 with the operation piece 36 as a boundary, an elastic protrusion 41 (corresponding to the release restricting portion of the present invention) protruding to the same side as the operation piece 36 protrudes in a deformable manner. It is installed. A locking claw 41 A projects from the tip of the locking claw 41 A and can be engaged with the locking claw recess 43 in the fitting portion 31. Thereby, the locking piece 33 is held at the release position. Further, the tip portion of the elastic protrusion 41 is substantially the same as the contact end surface 44 (the tip portion of the wall surface on which the engaging claw recess 43 is formed among the wall surfaces forming the fitting portion 31) at the lock position described later. Located at height.
[0022]
Similarly, a pair of left and right holding recesses 33A are formed in a recessed manner at the end of the locking piece 33 opposite to the holding recess 33B. Both holding recesses 33A are engaged with holding protrusions 31A formed in the fitting portion 31 so as to hold the locking piece 33 in the release position.
In FIG. 6, a guide piece fitting recess 34 formed in a semicircular shape is provided in a portion near the insertion hole 30 A of the guide groove 32, and a circular guide piece 35 is partly provided here. Can be screwed in a state of projecting into the guide groove 32. As a result, as shown in FIG. 8, a part of the locking piece 33 is pressed from behind (upward in FIG. 8), and the locking piece 33 can be smoothly slid without being detached from the guide groove 32.
[0023]
Next, the installation work of the winning ball collective cover 21 will be described. First, the guide path forming member 20 is attached to the back surface of the game board 19. For this purpose, the guide path forming member 20 is superposed on the back surface of the game board 19 and the base end portion 22A of each engagement receiving member 22 is fitted into the recess 19B of the game board 19 so that the guide path forming member 20 is fitted. Position it. Then, screws 26 are inserted into the respective mounting holes 25 of the guide path forming member 20 in this state, and are fastened to the game board 19 to fix the guide path forming member 20 to the back surface of the game board 19 (see FIG. 9). .
[0024]
On the other hand, the elastic protrusion 41 of the locking piece 33 is inserted into the four guide grooves 32 of the winning ball collective cover 21 while being bent, and is kept waiting at the release position. Then, a winning ball collective cover 21 is placed on the back surface of the game board 19 so as to cover the guide path forming member 20. Further, each engagement receiving member 22 on the guide path forming member 20 side is inserted through each insertion hole 30 A of the winning ball collective cover 21. As a result, the engagement receiving member 22 protrudes into each locking piece housing recess 30 of the winning ball collective cover 21 (see FIGS. 10 and 12). From here, each operation piece 36 is operated in the direction of the arrow in FIG. Then, since the locking piece 33 slides to the locked position, one end of the locking piece 33 is inserted into the locking piece coupling chamber 23 of the engagement receiving member 22. At this time, the elastic protrusion 41 is restored and deformed, and is positioned in the vicinity of the contact end face 44 (see FIG. 13). Furthermore, since the holding recess 33B of the locking piece 33 engages with the holding projection 24 in the locking piece coupling chamber 23, the locking piece 33 is held in the locked position. As a result, the locking piece 33 and the engagement receiving member 22 are in a coupled state (the state shown in FIGS. 11 and 13), and the winning ball collective cover 21 is held on the back surface of the game board 19. At this time, since the tip of the elastic protruding piece 41 is located at the same height as the contact end face 44, even if a force that accidentally moves the locking piece 33 to the release position works, The locking position is not released.
[0025]
Next, a case where the winning ball collective cover 21 is removed will be described. In the coupled state, the operation pieces 36 are respectively slid in the direction opposite to the arrow direction shown in FIG. 10 while the elastic protrusions 41 are pressed and bent. Then, the locking piece 33 is extracted from the locking piece coupling chamber 23 of the engagement receiving member 22 and moves to the release position. At this time, the holding recess 33A of the locking piece 33 is held in the fitting portion 31. It is engaged with 31A and held in that state. Thereby, since the coupling state of the locking piece 33 and the engagement receiving member 22 is released, the winning ball collective cover 21 can be removed from the game board 19.
[0026]
As described above, according to this embodiment, in order to attach the winning ball collective cover 21 to the back surface of the game board 19, first, the guide path forming member 20 is attached to the back face of the game board 19, and then the guide path forming member 20 is attached. It is only necessary to couple the locking piece 33 of the winning ball collective cover 21 to the engagement receiving member 22 provided integrally.
That is, in the series of operations for attaching the winning ball collective cover 21, the assembly operation of the engagement receiving member 22 alone is omitted. Therefore, in the present embodiment, since it is not necessary to individually assemble the engagement receiving members 22 as in the prior art, the positioning operation or the like is unnecessary, and the mounting operation of the winning ball collective cover 21 is facilitated.
[0027]
At this time, in addition to the engagement between the holding recess 33 B and the holding projection 24, there are two release regulating portions in which the elastic projection 41 of the locking piece 33 is in a position where it abuts against the abutting end surface 44. For this reason, accidental movement from the lock position to the release position is prevented. In this embodiment, the engaging force between the elastic protrusion 41 and the contact end surface 44 is set to be stronger than the engaging force between the holding recess 33 B and the holding protrusion 24.
Furthermore, since the engagement receiving member 22 and the guide path forming member 20 are integrated, the number of parts can be reduced, thereby reducing the economic burden such as mold cost and the administrative burden such as parts management. be able to.
[0028]
In addition, in the present embodiment, the relay board mounting base 37 is also formed integrally with the guide path forming member 20, so that individual positioning and mounting work with respect to the relay board mounting base 37 is not necessary. The burden on the area and economy can be reduced.
In addition, since a plurality of guide paths 28 corresponding to each winning ball receiving device are formed in the guide path forming member 20, when the game board 19 is newly developed, only this guide path forming member 20 is a new game. It is sufficient to correspond to the board 19.
[0029]
Second Embodiment
Next, a second embodiment of the present invention will be described with reference to FIGS.
In the present embodiment and the first embodiment, the same components are denoted by the same reference numerals, and a part of the description is omitted.
In the present embodiment, the cover locking member 51, the guide path forming member 50, and the relay board mounting base 52 in which the engagement receiving members 22 are arranged in a pair in the upper and lower directions are formed as separate bodies. Attached to the back side independently. That is, as shown in FIG. 16, a guide path forming member 50, a pair of cover locking members 51 on the left and right sides, and a relay board mounting base 52 are attached to the back surface of the game board 19 so as to cover these members. A winning ball collective cover 53 is attached to the.
[0030]
The guide path forming member 50 is formed of resin, and only the portions along the outside of the left edge and the lower edge of the opening 19A of the game board 19 are formed. The guide path forming member 50 is formed such that a plurality of guide paths 54 bulge to the back side corresponding to each winning ball receiving device arranged in the game area. Each guide path 54 is formed with the same effect as the guide path 28 in the first embodiment.
Further, a mounting hole 50 A is provided at a peripheral end portion of the guide path forming member 50 with a predetermined interval, and the screw 26 is fitted when the guide path forming member 50 is attached to the game board 19.
[0031]
Next, the same pair of cover locking members 51 are arranged on the left and right sides, and the engagement receiving members 22 are formed corresponding to the recesses 19B and 19B located above and below the game board 19. Further, an engaging convex portion 55 is provided at an intermediate portion of the cover locking member 51. When the winning ball collective cover 53 is assembled, the engaging convex portion 55 is concavo-convexly engaged with the engaging concave portion 56 on the winning ball collective cover 53 side, so that the winning ball collective cover 53 and the cover locking member 51 are fitted. This makes it easy to align the two parts and eliminates rattling after the two members are assembled.
[0032]
The relay board mounting base 52 is formed according to the shape of a relay board (not shown). As described in the first embodiment, a connector or the like for relaying a wiring to a decorative lamp or the like arranged in the game area or the like is arranged on the relay board. A mounting hole 52A is provided at a predetermined position around the relay board mounting base 52, and the screw 26 is fitted therein to fix the relay board mounting base 52 to the game board 19.
[0033]
The winning ball collective cover 53 is formed of a synthetic resin in a square shape so as to cover the guide path forming member 50 and the cover locking member 51 from the back side. The winning ball collective cover 53 is formed with an opening 53A larger than the opening 19A at a position corresponding to the opening 19A of the game board 19, and when the winning ball collective cover 53 is attached, both openings 19A. , 53A are matched.
Further, the left and right edge portions and a part of the upper edge portion (in FIG. 19, a part of both the left and right edge portions and the upper edge portion) of the winning ball collective cover 53 are slightly raised on the surface side. When the collective cover 53 is attached to the game board 19, a space capable of covering the guide path forming member 50 and the cover locking member 51 is formed with the game board 19. On the other hand, the lower edge portion of the winning ball collective cover 53 is formed so that both left and right end portions are connected to the left and right edge portions, but the other portions are not formed as such. For this reason, when the winning ball collective cover 53 is attached to the game board 19, the winning ball that forms an opening with the game board 19 on the lower surface and falls from the guide path 54 passes through this opening. It can be collected in the cage.

Further, as shown in FIG. 19 or 20, lock mechanisms 57 are respectively provided at the four corners of the winning ball collective cover 53, that is, at positions corresponding to the engagement receiving members 22 provided on the cover locking member 51. It is configured. The lock mechanism 57 is provided in the locking piece housing recess 30 and is formed in a long and narrow recess from the surface side to the side surface of the winning ball collective cover 53. An insertion hole 30 A is formed at one end of the latching piece receiving recess 30, and when the winning ball collective cover 53 is assembled to the back surface of the game board 19, the engagement receiving member 22 starts from here. It protrudes into the housing recess 30.
In addition, a locking piece holding projection 59 is projected from a portion of the guide groove 32 near the insertion hole 30A. When the locking piece 58 is attached to the guide groove 32, the locking piece holding projection 59 comes into contact with the side surface portion. For this reason, the locking piece 58 can be smoothly slid without being detached from the guide groove 32.
[0035]
An intermediate position between the upper and lower lock mechanisms 57 is an engagement recess 56. The engagement recess 56 can be engaged with the engagement protrusion 55 described above when the winning ball collective cover 53 is assembled to the cover locking member 51.
Further, the lower end portion of the winning ball collective cover 53 is provided with three guide walls 60 protruding from the rear surface at a position corresponding to the outlet 54A of the guide path 54. Inside each guide wall 60 is a passage 63 connected from the front surface to the bottom surface of the winning ball collective cover 53, and the winning ball guided to the outlet 54A at the lower end portion of the guide path 54 is located further below. Induced by the trap. By providing the guide wall 60 according to each guide path 54 in this way, the number of prize balls can be easily changed to, for example, seven or fifteen according to the position of the winning ball receiving device on the front of the play stand. Become.
Of the guide wall 60, a slit 61 is formed vertically and horizontally around a predetermined area around the center of the guide wall 60, so that the predetermined area around the guide wall 60 located at the center can be easily cut off. ing. Thereby, a big opening can be formed in the lower end part center part of the winning ball collective cover 53 as needed. This opening serves as an attacker projecting opening that matches the rear end portion of the attacker (not shown) that protrudes from the back surface of the gaming board 19 when a so-called attacker is installed, depending on the type of gaming board 19. .
[0036]
Note that ribs 62 protrude from the guide walls 60 formed on both sides at positions where the lower end edges are connected to each other. Since the rib 62 and the center guide wall 60 are separated from each other by the separation groove 64, the lower end edges of the guide walls 60 on both sides are connected by the rib 62 even after the center guide wall 60 is cut off. ing. For this reason, the rib 62 serves to reinforce the lower side of the winning ball collective cover 53 and makes it difficult for the lower end portion of the winning ball collective cover 53 to bend and deform.
Next, the locking piece 58 will be described. Unless otherwise specified, the position of FIG. 20 (corresponding to the lower left when the winning ball collecting cover 53 is viewed from the rear side) is referred to. To do.
As shown in FIG. 21, the locking piece 58 is integrally formed of a synthetic resin material, and slides up and down in the guide groove 32 to engage with the cover locking member 51 (shown in FIG. 23). Position) and a release position (position shown in FIG. 24) which is accommodated in the fitting portion 31 of the winning ball collective cover 53 and is not engaged with the cover locking member 51.
[0037]
The difference in configuration between the locking piece 58 of the present embodiment and the locking piece 33 of the first embodiment is only the presence or absence of the holding recess 33A. That is, in the locking piece 58 of this embodiment, since the holding recess 33A is not provided, when the locking piece 58 is in the release position, it is fitted only by the locking claw 41A at the front end portion of the elastic protrusion 41. Locked in the portion 31.
Next, the mounting work of the winning ball collective cover 53 will be described. First, the guide path forming member 50, the pair of cover locking members 51, and the relay board mounting base 52 are attached to the back surface of the game board 19.
[0038]
The guide path forming member 50 is aligned with a predetermined position on the back surface of the game board 19 and the screw 26 is inserted into the mounting hole 50A. Similarly, the relay board mounting base 52 is fixed with the screw 26 while being aligned with a predetermined position of the game board 19. On the other hand, each cover locking member 51 is positioned so that the base end portion 22A is fitted into the recess 19B of the game board 19 and screws 26 are inserted into the respective mounting holes 25, and these are attached to the game board 19. The cover locking member 51 is fixed to the back surface of the game board 19 by tightening.
[0039]
On the other hand, the elastic protrusions 41 of the locking pieces 58 are inserted into the four guide grooves 32 of the winning ball collective cover 53 while being bent, and kept waiting at the release position. At this time, the locking piece holding projection 59 holds the locking piece 58 so as to press the side surface of the locking piece 58, so that the locking piece 58 is not easily detached from the guide groove 32.
The procedure for assembling the winning ball collective cover 53 to the game board 19 is the same as that in the first embodiment, and is therefore omitted.
[0040]
Thus, according to this embodiment, the cover locking member 51 is formed by connecting the upper and lower two engagement receiving members 22. For this reason, in a series of operations for attaching the winning ball collective cover 53, as compared with the case where the cover locking members 51 are individually assembled as in the prior art, the assembling operation becomes easier and the positioning operation is not required. As a result, the work of attaching the winning ball collective cover 53 is facilitated.
In addition, since the cover locking member 51 and the guide path forming member 50 are separated, even when only the guide path forming member 50 has to be changed due to the development of a new model, the cover locking member 51 remains as it is. Can be used. For this reason, since it is only necessary to create a mold having only the guide path forming member 50, the economic burden can be reduced.
