Description

【０００１】
【産業上の利用分野】
この発明はパチンコ機に関し、特に、貯留されたパチンコ球の欠乏を検出する球切れ検出機構と、パチンコ球を順次球発射起点へ送り込む球送り機構と、球送り機構を開閉操作する中継機構とを含む球切れ検出装置の改良に関する。
【０００２】
【従来の技術】
遊技者に払い出されるパチンコ球が欠乏したときに球発射起点へのパチンコ球の供給を休止させる目的で設置される中継機構はベ−ス枠と、このベ−ス枠に結合された裏枠とにわたって取付けられ、裏枠をベ−ス枠に組付けるときに中継機構が組立てられる。
【０００３】
【発明が解決しようとする課題】
従来のこの種の中継機構では裏枠をベ−ス枠に結合するときに中継機構を構成する部材を連結したり、分離させる手数が煩雑となる問題点がある。
本発明は上記問題点を解消して賞品球用の補給貯留部での球切れ状態をより的確に検出し得るとともに、裏枠部材の開閉に伴う中継機構の連結および分離を簡易化することを課題とするものである。
【０００４】
【課題を解決するための手段】
請求項１のパチンコ機は、前枠部の前側下部に、遊技用のパチンコ球を受入れ得る上皿と、この上皿から通出されたパチンコ球をシャッタの開閉状態に基づき受入れて１個ずつ機内の球発射起点側へ送出し得る球送り機構とを備えた前板が組付けられる一方、前枠部の裏面に固定されて内部に遊技盤を嵌込みセットし得るベース枠の裏側に、補給用のパチンコ球を貯留する球タンクと、この球タンクの球排出口の下方に取着されて、該球タンクから通出したパチンコ球を受入れて下流の賞品球払い出し制御ユニット側へ２列にして誘導し得る球レールとを装着した裏枠が開閉可能に組付けられたパチンコ機において、
前記球レールの上流端部側に、該球レール内を流通するパチンコ球の貯留および減少を感知して状態変化し得る第１球切れ作動片と、この第１球切れ作動片に連繋変位し得るスイッチ操作用の係動片と、前記係動片の下方部位で該第１球切れ作動片の球感知変動を電気的に検出し得る２個の検出スイッチおよび１枚のスイッチ基板と、前記第１球切れ作動片の下流側位置で前記球レール内を流通するパチンコ球の貯留および減少を感知して状態変化し得る第２球切れ作動片と、この第２球切れ作動片に連繋変位して前記球送り機構に支持された前記シャッタとの間に亘り連繋されて第２球切れ作動片の状態変化を前記シャッタの開閉状態に伝動する中継機構とが装備されており、
前記第１球切れ作動片は、前記球レールの支持部に対して片持ち状態で上下揺動可能に支持されて少数個の球を受ける球受部を上向きに付勢して前記球レールの上流端部の内に延出して前記球タンクの球排出口の下方に臨ませ、
前記係動片は、前記第１球切れ作動片の支持部の反対側の先端部に連繋されて垂下状態で上下変位可能に支持されており、
前記検出スイッチは、前記球レールの上端部の下方位置で前記裏枠に形成された基板取付け部内に装入される前記スイッチ基板に個々に接続配置され、傾動可能に付勢された各々の触動片を前記係動片の下面に押接させて、前記係動片の下動により各触動片が押下されているときの球有り検出状態と、前記係動片の上動により各触動片が解放されたときの球切れ検出状態とに変化するようになっており、かつ、球切れ検出状態時に発する各々の検出信号を、賞品球切れ表示ランプと遊技場の管理装置とに対する各々の球切れ信号として出力しうるように設定し、
前記第２球切れ作動片は、前記球レールの支持部に対して片持ち状態で上下傾動可能に支持されて、球レール内の複数個のパチンコ球を受け得る球受部を上向きに付勢保持して前記球タンクの球排出口の下方に臨ませ、
前記中継機構は、前記第２球切れ作動片の支持部の反対側の先端部に連結されて前記裏枠の裏面に垂下状態で上下変位可能に支持された第１中継部材と、前記ベース枠の裏側下部の支持部に対して片持ち状態で上下傾動可能に支持される第２中継部材と、該第２中継部材３６の支持部の反対側の先端部に連結されて上下変位可能に支持され、前記球送り機構の球受口に対する前記シャッタの開閉状態を操作する第３中継部材とを備えており、
かつ、前記中継機構における前記第１中継部材と前記第２中継部材との間の連繋構成部分では、前記裏枠の下端部に一体状に形成されて縦長の通し孔を貫通して開口形成した拘持部と、前記第１中継部材の下端に前後の向きに連結されて前記拘持部に対しては通し孔に前後方向に挿通支持されたもとで、上下の変位が許容されるとともに前後方向に抜止め状態で拘束されて連携保持される連繋片と、前記第２中継部材の中央部に形成されて前記連繋片の前連繋部を前後方向に脱抜可能に挿通し得る挿通孔を貫通して開口形成した係合部とが構成されており、
前記裏枠の閉鎖状態時には、前記第１中継部材の前記連繋片の前連繋部が、前記第２中継部材の前記係合部の挿通孔に後方から挿通して連繋される一方、前記裏枠の後方への開放時には、前記第１中継部材の前記連繋片が、前記拘持部に保持された状態のまま、該連繋片の前連繋部が、前記係合部の挿通孔から後方に抜脱分離されるように設定された構成を有する。
【０００７】
【作用】
請求項１に記載のパチンコ機では、球タンク内の貯留球が無くなり球レールの上流端部内の貯留球が減少すると、まず、第１球切れ作動片が、球受部で受ける球圧（球重量）から解放されて上傾変化（球切れ状態）されるとともに、これに追従して係動片が引上げられて２個の検出スイッチの触動片をともに解放する。これにより各球切れ検出スイッチは、個々の触動片が上傾復帰されることにより、「球切れ検出状態」として検出信号を発生する。そしてこの各検出信号が、スイッチ基板を介して賞品球切れ表示ランプに対する球切れ信号、遊技場の管理装置に対する球切れ信号として出力されることに伴い、表示ランプが点灯表示される。
【０００８】
次いで、前記球レールの上流端部内の球無し（球切れ）後に球レールの上流部内の貯留球が減少（一般的には、球補給作動の一時的な遅れに起因する球タンクへの球投入不足と、賞品球払い出しとによる減少）した場合、前記第１球切れ作動片の下流部に位置する第２球切れ作動片が、球受部で受ける球圧から解放されて上傾変化（球切れ状態）される。これに追従して中継機構が球切れ状態に連動されることにより、即ち、第１中継部材の上動変位、第２中継部材の上傾変位、第３中継部材の上動変位により、球送り機構におけるシャッタが、第３中継部材で押上げ操作されて球受口に対する閉鎖状態（球通し不能状態）に拘束保持される。これにより遊技用パチンコ球の球発射起点への送込み（球送り）が停止されて打球発射が暫時不能停止される。
【０００９】
そして、請求項１に記載のパチンコ機において、遊技盤の裏側点検等の必要に伴い裏枠が開放される場合には、ベース枠側に対する裏枠の後方への回動に伴い前記球レール側の第２球切れ作動片に連繋されている中継機構において、裏枠の裏側に支持されている第１中継部材の下端の連繋片が、裏枠の拘持部に保持されたまま後方へ変移しながら、その前連繋部をベース枠裏側の第２中継部材における係合部の挿通孔から後方へ速やかに抜出すことにより、裏枠側の第１の中継部材がベース枠側の第２中継部材に対してごく自然状態で分離される。
また、遊技盤の裏側点検等の終了等に伴い裏枠が元の閉鎖状態に設置される場合には、裏枠の前方への回動に伴い前記中継機構における第１中継部材の連繋片が拘持部に保持されたまま前方へ変移しながら、その前連繋部を第２中継部材における係合部の挿通孔に後方から前方へ挿通される。これにより第２中継部材に対して第１中継部材が元状態に連繋保持されて、中継機構全体が本来の球切れ検知状態に保持される。
【００１０】
【発明の効果】
請求項１に記載のパチンコ機では、球タンク内の貯留球が無くなり球レールの上流端部内の貯留球が減少すると、まず、第１球切れ作動片が、球圧（球重量）から解放されて上傾変化されることに追従して、係動片が引上げられて２個の検出スイッチの触動片をともに解放する。これにより各球切れ検出スイッチから発生された各検出信号により、賞品球切れ表示ランプが点灯されて「球切れ状態」を表示することができる。
【００１１】
また、前記第１球切れ作動片および検出スイッチによる球切れ検知において、前記球レールの上部内の貯留パチンコ球が減少した場合には、第２球切れ作動片が球圧から解放されて上傾変化されることに追従して、中継機構が球切れ状態に連動されることにより、上皿裏側の球送り機構のシャッタが、球受口に対する球通し不能な閉鎖状態に拘束保持される。これにより遊技用パチンコ球の球発射起点への送込み（球送り）を停止させて、打球発射を暫時不能停止（中断）させることができる。
【００１２】
このようなパチンコ機において、遊技盤の裏側点検等の必要に伴い裏枠を開放する場合には、ベース枠側に対する裏枠の後方への回動に伴い中継機構における第１中継部材の連繋片が裏枠の拘持部に保持されたまま後方へ変移しながら、その前連繋部をベース枠裏側の第２中継部材における係合部の挿通孔から後方へ速やかに抜出し得ることにより、第２中継部材に対して第１中継部材を分離することができる。
また、遊技盤の裏側点検等の終了等に伴い裏枠を元状態に設置する場合には、裏枠の前方への回動に伴い前記第１中継部材の連繋片が拘持部に保持されたまま前方へ変移しながら、その前連繋部を第２中継部材における係合部の挿通孔に後方から前方へ挿通し得ることにより、第２中継部材に対して第１中継部材を連繋して、中継機構全体を何ら破損することなく本来の球切れ検知状態に保持し得、中継機構全体の復旧に要する手間が省略できる。
【００１５】

ベ−ス枠２の後側にはベ−ス枠２に前後方向へ回動可能で取外し可能に結合されて前方の回動端でベ−ス枠２に解離可能に係止される裏枠１６が設置されている。
【００２６】
裏枠１６は前方の回動端で遊技盤３の裏側に重ね合わされ、この状態で裏枠１６をベ−ス枠２に係止すると、裏枠１６が遊技盤に押しつけられて遊技盤３がベ−ス枠２に固止される。
【００２７】
図１，図３において、裏枠１６の上縁部の裏面には遊技者に払い出されるパチンコ球を貯留する球タンク１７が取外し可能に結合され、この球タンク１７の底板１７ａの外端部には貯留されたパチンコ球が通過する球排出口１７ｂが開設されている。
【００２８】
球タンク１７の球排出口１７ｂの下方にはパチンコ球を裏枠１６の一方の側枠部の裏面に取付けられた賞品球払い出しユニット１９側へ前後２列にして誘導する半透明合成樹脂製の球レ−ル１８が設置されている。
【００２９】
球レ−ル１８には賞品球払い出しユニット１９側に向かって先下り状に傾斜した底板１８ａと、この底板１８ａの後端縁に連接されて垂立された縦壁板とが形成され、底板１８ａの基端部付近には球タンク１７の球排出口１７ｂの直下に配設された検出口１８ｂが開設され（図３参照）、球レール１８の基端部付近の前面には金属薄板若しくは金属箔板によって形成されてア−ス用のリ−ド線が接続された静電気防止用の帯電防止板４２が重ね合わされて固定されている。
【００３０】
帯電防止板４２には球レ−ル１８内の基端部付近を後方から透視するための透視窓４２ａが開設されている。
【００３１】
球レ−ル１８の検出口１８ｂ内には球レ−ル１８に挿着された支軸２２によって検出口１８ｂ内の外端部で上下方向への揺動可能に支持された第１球切れ作動片２０と、球レ−ル１８に突設された支軸２３によって第１球切れ作動片２０の下流側（図３中右方）で揺動可能に支持され、第１球切れ作動片２０の球受部の長さより延長された長さを有する球受部２１ａが形成された第２球切れ作動片２１とが検出口１８ｂを閉塞した状態で隣合って設置されている。両球切れ作動片２０，２１は第１球切れ作動片２０の球受部上のパチンコ球がその自重で第２球切れ作動片２１の球受部２１ａ上へ転落するように配列されている。
【００３２】
第１球切れ作動片２０の先端部には第１球切れ片２０の揺動動作によって上下方向へ変位する係動片２４がその上端の軸部２４ａによって結合されている。
【００３３】
球レ−ル１８の検出口１８ｂの外端部の下方位置で裏枠１６に一体状に突出形成された基板取付け部２６内にはスイッチ基板２７が装入されており（図３参照）、このスイッチ基板２７上には内部のスプリング（図示しない）で上方に付勢された触動片２８ａを有する１対の球切れ検出スイッチ２８が設置されている。なお、両球切れ検出スイッチ２８内のスプリングが、第１球切れ作動片２０を上向きに付勢することになる。
【００３４】
係動片２４の下端部は両球切れ検出スイッチ２８の触動片２８ａに当接され、第１球切れ作動片２０がその上に載置されたパチンコ球の重量によって押下げられて下方へ揺動すると、係動片２４が下方へ変位して球切れ検出スイッチ２８の触動片２８ａが係動片２４によって押下げられた状態で保持される。
【００３５】
第１球切れ作動片２０の球受部上のパチンコ球が限度以下に少なくなると、第１球切れ作動片２０が球圧から解放されて球切れ検出スイッチ２８内のスプリングの付勢力により揺動され、これに連繋して係動片２４が上動し、両球切れ検出スイッチ２８の触動片２８ａが解放されて上方へ揺動し、両球切れ検出スイッチ２８の接点が同時に切り換えられて一方の球切れ検出スイッチ２８が球切れ信号を出力し、遊技盤面に取付けられた賞品球切れ表示ランプが点灯し、また、他方の球切れ検出スイッチ２８が遊技場の管理装置に球切れ信号を出力する。
【００３６】

第２球切れ作動片２１の球受部２１ａはその上に載置されたパチンコ球群の重量によって下方へ揺動し、球受部２１ａ上のパチンコ球の個数が限度以下に少なくなって球切れ状態になると、スプリング２９の弾発力によって上方へ揺動する。
【００３８】
第１球切れ作動片２０上に載置されるパチンコ球の個数は第２球切れ作動片２１の球受部２１ａ上に載置されるパチンコ球の個数より少なく、球切れ時に第１球切れ作動片２０上に残留するパチンコ球の個数は第２球切れ作動片２１の球受部２１ａ上に残留するパチンコ球の個数より少なくなるように設定されている。
【００３９】
両球切れ作動片２０，２１上のパチンコ球の個数が少なくなって球切れ状態になると、始めに、第１球切れ作動片２０上のパチンコ球の個数が限度以下となって第１球切れ作動片２０が上方へ揺動し、球切れ検出スイッチ２８が球切れ信号を出力し、続いて、第２球切れ作動片２１上のパチンコ球の個数が限度以下となって第２球切れ作動片２１の球受部２１ａが上方へ揺動し、第２球切れ作動片２１は第１球切れ作動片２０の作動時点から若干遅れて作動する。
【００４０】
第２球切れ作動片２１の動きを球送り機構８のシャッタ１４に伝える中継機構は裏枠１６の裏側とベ−ス枠２の下部の後側とにわたって設置されている。
【００４１】
中継機構の第１の中継部材３１は、細い金属線材（針金）によって形成されて上下方向に沿って設置された連繋杆３２と、この連繋杆３２の下端部３２ｂに取外し可能に結合された合成樹脂製の連繋片３３とを備え、裏枠１６の後面側に上下動可能に取付けられている。
【００４２】
連繋杆３２の上端部３２ａは第２球切れ作動片２１の球受部２１ａの先端付近に掛止され、第１の中継部材３１は第２球切れ作動片２１の球受部２１ａの上下方向への揺動動作に連動して上下動する。
【００４３】
連繋片３３にはその中央部付近に突設された円盤状のフランジ部３３ａと、このフランジ部３３ａの前面の中心部に連接されて前方へ突出され、先端部に丸味が付与された丸棒状の前連繋部３３ｂと、フランジ部３３ａの後面の中心部に連接されて後方突出され、連繋杆３２の下端部３２ｂが取外し可能に結合された円筒状の後連繋部３３ｃとが形成されている。
【００４４】
裏枠１６の他方の側枠部の後面下部には連繋杆３２がその断面方向への動きが制限された状態で挿通および支持された連繋杆支持部３４が突設されるとともに、裏枠１６の下枠部にはその下面に連接されて下方へ突出され、連繋片３３を上下方向への移動可能で水平方向への移動不能に拘束支持して連繋片３３の下方の移動端を規定する拘持部３５が一体状に形成されている。

【００４７】
中継機構の第２の中継部材３６は合成樹脂材によって横長状に形成され、ベ−ス枠２の下部後面に突設された軸部３９によって上下方向への揺動可能に支持された状態でベ−ス枠２の後面に取付けられている。
【００４８】
ベ−ス枠２の後面には第２の中継部材３６の下方の揺動端を規定するストッパ４４が突設されている。
【００４９】
ベ−ス枠２の下部の後面に突設された突部４６には金属線材によって形成されてベ−ス枠２の前側から後側にわたって設置され、前端部がシャッタ１４の受動部１４ａの下側に挿入されて第２の中継部材３６の動きをシャッタ１４に伝える第３の中継部材４０が貫挿されている。この中継部材４０は、図２，図４，図５に例示するように第２の中継部材３６の支持部の反対側の先端部に連結されて垂下状で前記突部４６に挿通支持されており、そしてベース枠２の前方へ貫挿された中継部材４０の前端部が、シャッタ１４の受動部１４ａの下側に前後方向への係脱可能に挿入した状態で連繋されている。
【００５０】
第２の中継部材３６には帯板状に基片３６ａと、この基片３６ａの基端部に連接されて軸部３９が嵌挿された円筒状の軸挿部３６ｂと、基片３６ａの先端部に連接されて第３の中継部材４０の後端部が掛止された掛止部３６ｃと、軸挿部３６ｂの内方位置で基片３６ａに連接されて連繋片３３の、前連繋部３３ｂが脱出可能で連動可能に係合された係合部３６ｄとが形成されている。
【００５１】
第２の中継部材３６の係合部３６ｄには裏枠１６が第１の中継部材３１とともに前回動端へ回動したときに連繋片３３の前連繋部３３ｂが挿通される丸孔状の挿通孔３７が形成されるとともに、係合部３６ｄには、挿通孔３７の後側に挿通孔３７を包用するように隣設されて断面積が後方から前方へ漸減するすりばち面状の凹曲面形状を有し、連繋片３３の前連繋部３３ｂが挿通孔３７に挿通される直前に連繋片３３の先端部を連繋片３３の上下方向の全移動範囲にわたって滑動させて挿通孔３７側へ案内する案内面３８が形成されている。
【００５２】
案内面３８の前端縁は丸孔状で挿通孔３７の後側孔縁に連接され、案内面３８の後端縁は連繋片３３の上下方向の移動距離より拡大された長径部を有する縦長の楕円形状に形成され、案内面３８の上部には上方へ移動した連繋片３３を案内する上案内部３８ａが形成され、案内面３８の下部には下方へ移動した連繋片３３を案内する下案内部３８ｂが形成されている。
【００５３】
裏枠１６が第１の中継部材３１とともに前方の回動端の若干手前まで回動すると、第１の中継部材３１が上方へ変位した状態であっても下方へ変位した状態であっても連繋片３３の先端部が第２の中継部材３６の案内面３８に突き当たって前方への連繋片３３の移動に伴って挿通孔３７側へ滑動し、裏枠１６を前方の回動端へ回動すると、連繋片３３の前連繋部３３ｂが挿通孔３７内に自動的に挿通されて第１の中継部材３１が第２の中継部材３６に自動的に連結される。
【００５４】
両球切れ作動片２０，２１上のパチンコ球が限度以下に減少して第１球切れ作動片２０が上方へ揺動し、続いて、第２球切れ作動片２１の球受部２１ａが上方へ揺動すると、第１の中継部材３１の連繋杆３２が上動して連繋片３３が上方へ変位し、第２の中継部材３６が上方へ揺動して第３の中継部材４０が引上げられ、シャッタ１４の受動部１４ａが第３の中継部材４０によって押上げられることにより、図２のようにシャッタ１４が実線で示される通常の球送り可能位置から想像線で示される球送り不能位置に回動変化してその球止め部１４bで球受口１０を遮断し、球発射起点５へのパチンコ球の供給を不能とする。
【００５５】
続いて、上記した構成を有する実施例の作用と効果を説明する。ベ−ス枠２に前後方向への回動可能に結合された裏枠１６の後側には球切れ時に作動する第２球切れ作動片２１に上端部３２ａが係止された連繋杆３２と、この連繋杆３２の下端部３２ｂに結合された連繋片３３とを有し、第２球切れ作動片２１に連動して上下動する第１の中継部材３１を設置し、球発射起点５に通ずる球受口１０を開閉するシャッタ１４に連繋された状態でベ−ス枠２の後側に設置された第２の中継部材３６には裏枠１６が前方の回動端へ回動したときに連繋片３３が脱出可能に係合する係合部３６ｄを形成し、裏枠１６には連繋片３３を上下方向への移動可能で水平方向への移動不能に支持して連繋片３３の移動端を規定する拘持部３５を形成し、係合部３６ｄには裏枠１６が前方の回動端へ回動したときに連繋片３３の一部が挿通される挿通孔３７と、裏枠１６が前方の回動端付近へ回動したときに連繋片３３をその全移動範囲にわたって挿通孔３７側へ案内する案内面３８とを形成してある。
【００５６】
このため、第１の中継部材３１を裏枠１６に組付け、第２の中継部材３６をベ−ス枠２に組付けると、第２球切れ作動片２１の動きをシャッタ１４に伝える中継機構をベ−ス枠２と裏枠１６とにわたって設置することができるとともに、裏枠１６を後方へ回動させると、両中継部材３１，３６を自動的に分離させることができる。
【００５７】
例えば、第１の中継部材３１の連繋片３３を裏枠１６に一体状に形成された拘持部３５に係合させた状態でまず裏枠１６をベース枠９に装着すると、連繋片３３が第２の中継部材３６を介してシャッタ１４に連繋された状態でセットされ、その後連繋杆３２を連繋片３３に結合することによって第２球切れ作動片２１とシャッタ１４とを連繋することができ、また、連繋片３３を拘持部３５に係合させて連繋杆３２を連繋片３３に結合してから、拘持部３５を裏枠１６とともにベース枠９に装着することによっても、第２球切れ作動片２１とシャッタ１４とを連繋することができるので、パチンコ機が組立てられた状況に合わせて第２球切れ作動片２１とシャッタ１４とを連繋する作業を行うことができる。
【００５８】
従って、ベ−ス枠２や裏枠１６に取付けられた部品の故障時や遊技盤３の交換時に両中継部材３１，３６を分離させた状態で故障を修復したり、遊技盤３を交換することができるとともに、故障の修復後や遊技盤３の交換後に裏枠１６をベ−ス枠２に結合することによって両中継部材３１，３６を的確に再連結することができる。

また、第１の中継部材３１が連繋杆３２と連繋片３３とに分割され、連繋片３３が第２の中継部材３６の係合部３６ｄに脱出可能に係合するので、第１の中継部材３１と第２の中継部材３６とを的確に連結したり、分離させることができるとともに、第１の中継部材３１の動きを第２の中継部材３６に的確に伝えることができる。
【００６０】
さらに、連繋片３３を裏枠１６の拘持部３５によって拘束して連繋片３３の移動範囲を拘持部３５によって制限してあるので、連繋片３３の姿勢の変動や過剰移動を抑止して連繋片３３の動きを安定化することができるとともに、第２球切れ作動片２１の動きを第１の中継部材３１によって第２の中継部材３６に的確に伝えることができる。
【００６１】
また、第２の中継部材３６に案内面３８を形成してあるので、裏枠１６を前方の回動端へ回動させるだけで両中継部材３１，３６を的確かつ自動的に連結することができるとともに、球切れが発生して連繋片３２が上方へ移動した状態であっても、連繋片３２が下方へ変位した状態であっても、両中継部材３１，３６を的確に連結することができる。
【００６２】
また、連繋片３３が合成樹脂製で連繋片３３の水平方向への移動が拘持部３５によって阻止されるので、連繋片３３の先端部を案内面３８によって円滑に誘導して係合部３５ｄに無理なく係合させることができる。
【００６３】
さらに、第１の中継部材３１は細い金属線材によって形成された連繋杆３２の端部を合成樹脂製の連繋片３３によって補強した構造となるので、連繋杆３２が折れ曲ったり、損傷する不具合を解消することができる。
【００６４】
また、裏枠１６の拘持部３５には連繋片３３の左右方向の移動を規制して上下方向の移動を許容するガイド溝３５ａ、通し孔３５ｃが形成されているので、連繋片３３と連繋杆３２とを上下方向の位置合わせのみによって結合することができ、また連繋片３３の上下方向の移動範囲が拘持部３５によって規定されているので、第２球切れ作動片２１とシャッタ１４とを連繋する作業を僅かな調整範囲内で行うことができる。

It has the structure set so that it may be separated.
[0007]
[Action]
In the pachinko machine according to claim 1, when the stored ball in the ball tank disappears and the stored ball in the upstream end portion of the ball rail decreases, first, the ball pressure (ball It is released from the weight) and is tilted upward (out of the ball). Following this, the engaging piece is pulled up to release both of the detecting pieces of the two detection switches. As a result, each ball break detection switch generates a detection signal as a “ball break detection state” when the individual touching piece is returned to an upward tilt. Each of the detection signals is output through the switch board as a ball-out signal for the prize-out-of-ball display lamp and a ball-out signal for the game hall management device .
[0008]
Next, after the absence of a ball in the upstream end of the ball rail (out of ball), the number of stored balls in the upstream portion of the ball rail decreases (generally, the ball is thrown into the ball tank due to a temporary delay in the ball supply operation) In the case of shortage and decrease due to prize ball payout), the second ball-cutting piece located downstream of the first ball-cutting piece is released from the ball pressure received by the ball receiving part and changes upward (ball) Cut out). Following this, the relay mechanism is interlocked with the ball-out state, that is, the ball is fed by the upward displacement of the first relay member, the upward displacement of the second relay member, and the upward displacement of the third relay member. The shutter in the mechanism is pushed up by the third relay member and restrained and held in a closed state (a state in which the ball cannot pass) with respect to the ball receiving port. As a result, the game pachinko balls are stopped from being delivered to the starting point (ball feeding), and the hitting of the hitting ball is stopped for a while.
[0009]
In the pachinko machine according to claim 1, when the back frame is opened due to the need for inspection of the back side of the game board, the ball rail side as the back frame is rotated with respect to the base frame side. In the relay mechanism connected to the second ball-cutting operation piece, the connecting piece at the lower end of the first relay member supported on the back side of the back frame is moved backward while being held by the holding portion of the back frame. On the other hand, the first relay member on the back frame side becomes the second relay on the base frame side by quickly pulling out the front connecting portion rearward from the insertion hole of the engaging portion in the second relay member on the back side of the base frame. It is separated from the member in a very natural state .
In addition, when the back frame is installed in the original closed state due to completion of the backside inspection of the game board, etc., the connecting piece of the first relay member in the relay mechanism is moved along with the forward rotation of the back frame. The front connection portion is inserted from the rear to the front through the insertion hole of the engagement portion of the second relay member while moving forward while being held by the holding portion. As a result, the first relay member is linked and held in the original state with respect to the second relay member, and the entire relay mechanism is held in the original broken ball detection state.
[0010]
【The invention's effect】
In the pachinko machine according to claim 1, when the stored ball in the ball tank disappears and the stored ball in the upstream end of the ball rail decreases, first, the first ball breaker operating piece is released from the ball pressure (ball weight). Following the upward tilt change, the engaging piece is pulled up to release the two detecting switch touching pieces together. Thereby, the prize-out-of-ball display lamp is turned on by each detection signal generated from each of the out-of-ball detection switches, and the “out-of-ball state” can be displayed .
[0011]
Further, in the ball breakage detection by the first ball breaker operating piece and the detection switch, when the stored pachinko balls in the upper part of the ball rail are reduced, the second ball breaker operating piece is released from the ball pressure and tilted upward. Following the change, the relay mechanism is interlocked with the ball-out state, whereby the shutter of the ball feeding mechanism on the back side of the upper pan is restrained and held in a closed state in which the ball cannot pass through the ball receiving port. Thereby, the feeding (ball feeding) of the game pachinko ball to the ball firing starting point is stopped, and the hitting of the hit ball can be stopped (interrupted) for a while.
[0012]
In such a pachinko machine, when the back frame is opened due to the need for inspection of the back side of the game board, etc., the connecting piece of the first relay member in the relay mechanism as the back frame is rotated backward with respect to the base frame side The second connecting member can be quickly pulled out rearward from the insertion hole of the engaging portion in the second relay member on the back side of the base frame while moving rearward while being held by the holding portion of the rear frame. The first relay member can be separated from the relay member.
In addition, when the back frame is installed in the original state upon completion of the backside inspection of the game board, etc., the connecting piece of the first relay member is held by the holding portion as the back frame rotates forward. The first relay member is connected to the second relay member by allowing the front connection portion to pass through the insertion hole of the engaging portion of the second relay member from the rear to the front while changing forward. Thus, the entire relay mechanism can be maintained in the original ball breakage detection state without any damage, and the labor required to restore the entire relay mechanism can be omitted.

Subsequently, the operation and effect of the embodiment having the above-described configuration will be described. On the rear side of the back frame 16 coupled to the base frame 2 so as to be pivotable in the front-rear direction, a connecting rod 32 having an upper end 32a locked to a second ball-cutting piece 21 that operates when the ball is cut off. The first relay member 31 that has a connecting piece 33 coupled to the lower end portion 32 b of the connecting rod 32 and moves up and down in conjunction with the second ball breaking operation piece 21 is installed at the ball launching point 5. When the back frame 16 rotates to the front rotation end of the second relay member 36 installed on the rear side of the base frame 2 in a state of being connected to the shutter 14 that opens and closes the ball receiving port 10 that communicates. An engaging portion 36d is formed to engage the connecting piece 33 so that the connecting piece 33 can be withdrawn. The connecting piece 33 is supported on the back frame 16 so that the connecting piece 33 can move in the vertical direction and cannot move in the horizontal direction. A holding portion 35 that defines the end is formed, and the connecting piece 33 is formed in the engaging portion 36d when the back frame 16 is rotated to the front rotation end. An insertion hole 37 through which a part is inserted, and a guide surface 38 that guides the connecting piece 33 toward the insertion hole 37 over the entire movement range when the back frame 16 rotates to the vicinity of the front rotation end are formed. It is.
[0056]
For this reason, when the first relay member 31 is assembled to the back frame 16 and the second relay member 36 is assembled to the base frame 2, the relay mechanism transmits the movement of the second ball-breaking working piece 21 to the shutter 14. Can be installed over the base frame 2 and the back frame 16, and when the back frame 16 is rotated rearward, the relay members 31 and 36 can be automatically separated.
[0057]
For example, when the back frame 16 is first attached to the base frame 9 in a state where the connecting piece 33 of the first relay member 31 is engaged with the holding portion 35 formed integrally with the back frame 16, the connecting piece 33 is removed. It is set in a state where it is connected to the shutter 14 via the second relay member 36, and then the second ball cutting operation piece 21 and the shutter 14 can be connected by coupling the connecting rod 32 to the connecting piece 33. Alternatively, the connecting piece 33 is engaged with the holding portion 35 and the connecting rod 32 is coupled to the connecting piece 33, and then the holding portion 35 is attached to the base frame 9 together with the back frame 16, the second Since the ball break operating piece 21 and the shutter 14 can be linked, the operation of linking the second ball cut working piece 21 and the shutter 14 can be performed in accordance with the situation in which the pachinko machine is assembled.
[0058]
Accordingly, when a part attached to the base frame 2 or the back frame 16 fails or when the game board 3 is replaced, the failure is repaired with the relay members 31 and 36 separated, or the game board 3 is replaced. In addition, both the relay members 31 and 36 can be accurately reconnected by connecting the back frame 16 to the base frame 2 after repairing the failure or after replacing the game board 3.
[0059]
Moreover, since the 1st relay member 31 is divided | segmented into the connection collar 32 and the connection piece 33, and the connection piece 33 engages with the engaging part 36d of the 2nd relay member 36 so that it can detach | extract, the 1st relay member 31 and the second relay member 36 can be accurately connected or separated, and the movement of the first relay member 31 can be accurately transmitted to the second relay member 36.
[0060]
Further, since the connecting piece 33 is restrained by the holding portion 35 of the back frame 16 and the movement range of the connecting piece 33 is limited by the holding portion 35, the posture variation and excessive movement of the connecting piece 33 are suppressed. The movement of the connecting piece 33 can be stabilized, and the movement of the second ball break working piece 21 can be accurately transmitted to the second relay member 36 by the first relay member 31.
[0061]
Further, since the guide surface 38 is formed on the second relay member 36, the relay members 31 and 36 can be accurately and automatically connected by simply rotating the back frame 16 to the front rotation end. In addition, the relay members 31 and 36 can be accurately connected even when the ball piece is broken and the connecting piece 32 is moved upward or the connecting piece 32 is displaced downward. it can.
[0062]
In addition, since the connecting piece 33 is made of synthetic resin and the movement of the connecting piece 33 in the horizontal direction is prevented by the holding portion 35, the leading end portion of the connecting piece 33 is smoothly guided by the guide surface 38, and the engaging portion 35d. Can be engaged without difficulty.
[0063]
Furthermore, since the first relay member 31 has a structure in which the end portion of the connecting rod 32 formed of a thin metal wire is reinforced by the connecting piece 33 made of synthetic resin, the connecting rod 32 is bent or damaged. Can be resolved.
[0064]
Further, the holding portion 35 of the back frame 16 is formed with a guide groove 35a and a through hole 35c that restrict the movement of the connecting piece 33 in the left-right direction and allow the moving in the vertical direction. The hook 32 can be coupled only by vertical alignment, and the vertical movement range of the connecting piece 33 is defined by the holding portion 35, so that the second ball break working piece 21, the shutter 14, Can be performed within a slight adjustment range.
