Description

【考案の詳細な説明】【０００１】【産業状の利用分野】本考案は、遊技盤を装着する基板表面に発射杵によって打ち出された打球を案内する発射レールを着脱自在に設けるパチンコ機の発射レール取付装置に関するものである。【０００２】【従来技術】パチンコ機の発射レールは打球の正しい弾道を定める上で重要である。そこで、従来は、発射レールが位置ずれを起さぬように、パチンコ機の基板に対し発射レールをビスにより固く止着していた。しかし、発射レールには球垢が付着し易く、遊技店ではこの球垢を除くため毎に拭取作業をしているが、この拭取作業時に加えられる押圧力により、発射レールに狂いや歪みが生じることが少なくない。このような発射レールについては、抜取作業時に余分な力が発射レールにかからないように取り外してから抜取作業が行なえるか、もしくは狂いや歪みが生じてしまった発射レールについては交換することが必要である。しかし、ビス止めによる従来の取付構造では、遊技店における交換作業に手間が掛る。このため営業中に発射レールの交換を行なうような場合、当該パチンコ機の使用ができない時間が長くなるという不都合があった。【０００３】【考案が解決しようとしする問題】かかる問題点に鑑み、本考案者等は、まだ公知ではないが、工具を必要としないでワンタッチで発射レールを取り付け取り外しできるパチンコ機の発射レール取付装置を提案している（実願昭６１−１１０９４号）。即ち、レール本体及びその担持体で発射レールを構成し、この発射レールの担持体と基板とに同心的に取付孔を設け、この取付孔に取付部材の軸を差込んで操作部をひねり、該軸の先端部のＴ字状係止部を基板裏面に係合させ、取付部材の鍔部とこの係止部とにより基板と発射レールとを挟み、以って発射レールを着脱自在に固定する構造である。【０００４】しかし、上記の発射レール取付装置は、片持ち支持されるレール本体の担持体の下方のみを基板に固定する構造となっているので、比較的長期のレール本体の適正位置の保持に困難があった。即ち、担持体の下方のみを固定した場合、適正位置に保持すべき発射レールの基板当接側上部つまりレール本体自体が、使用による経時的な変化として、徐々に前方に倒れて来てしまい、発射誘導溝が傾いた状態となり、発射杵によって打出されるパチンコ球の弾道が適正位置からずれて来るという問題点があった。本考案は、上記問題点を解決するもので、工具を用いずに簡単に取り付け取り外しができると共に、長期的に見ても発射レールを適正位置に保持できる発射レール取付装置の提供を目的とするものである。【０００５】【問題を解決するための手段】本考案は、上記目的を達成するため、遊技盤（１）を装着する基板（２）表面に、発射杵（４）によって打ち出された打球を案内する発射レール（１０）を着脱自在に設けるパチンコ機の発射レール取付装置に於て、上記発射レール（１０）は、長手方向に沿って発射誘導溝（１３ａ）を形成したレール本体（１１）と、該レール本体（１１）の内側に装着した担持体（１２）とから一体的に形成し、上記担持体（１２）は、該担持体（１２）の基板（２）表面側部分には、その部分から突出する係合部（２５）を設けると共に、担持体（１２）の下方側部分には基板（２）に取り付けるための取付部（１６）を延出させ、上記基板（２）側には、上記担持体（１２）の係合部（２５）に対応して該係合部（２５）が係止される係止部（２６）と担持体（１２）の取付部（１６）に対応して該取付部（１６）を固定する固定手段（２８）とを各々形成して、基板（２）に対して発射レール（１０）を、担持体（１２）の係合部（２５）を基板（２）の係止部（２６）に係止させると共に担持体（１２）の取付部（１６）を固定手段（２８等）により着脱自在に固定して、発射レール（１０）の発射誘導溝（１３ａ）を適正状態に維持できるようにしたことを特徴とするものである。【０００６】【作用】本考案によれば、先ず、基板（２）に対して発射レール（１０）を、担持体（１２）の係合部（２５）を基板（２）の係止部（２６）に係止させ、その後、担持体（１２）の取付部（１６）を固定手段（２８等）によって、着脱自在に固定するので、片持ち支持構造の発射レール（１０）であっても、係合部（２５）と係止部（２６）との係止により固定された発射レールを取り付けた状態において、清掃時における外部押圧力や使用による経年変化が作用しても、発射レール（１０）の発射誘導溝（１３ａ）は常に適正状態に維持される。【０００７】【実施例】以下、本考案を実施例に基づいて説明する。第１図及び第２図に於て、本考案の発射レール取付装置は、パチンコ機の遊技盤１の下部に配設された基板２と、該基板２の正面に装着される発射レール１０とで構成される。基板２は、この例では、第３図に示すように遊技盤載置部２Ａを有する箱状のフレームである。発射レール１０は、ガイドレール３と協働して、発射杵４からの打球を遊技領域１Ａへ導く役目をするもので、発射レール１０とガイドレール３との間には、打出されたファール球即ち遊技領域１Ａに達せずにガイドレール３を流下する打球を、受皿５へ導びくファール球回収樋６の受口６Ａ（第２図）が開口している。【０００８】発射レール１０は、打出された打球の方向や回転等を正しく規制し、打球をガイドレール３上に適正且つ安定した走行状態で移動できるように、発射誘導するものであり、パチンコ機の最も重要な部分の１つである。即ち、発射レール１０が正しく取付けられ且つその取付位置が安定していないと、打球が遊技領域１Ａに達する迄に遊技盤との摩擦その他により弾発勢が減殺され、発射杵４により球に与えるべきエネルギーが大きくなり、その結果打球発射装置の操作部４Ａをより多く右に回動させておかなければならなくなり、遊技者が疲れる原因となる。これは発射レール１０からガイドレール３への打球の移動が良好でない場合に起因することが多い。【０００９】又、極端に取付位置が狂った場合には、発射レール１０からガイドレール３への打球の移動すらできなくなり、パチンコ機本来の機能を失うからである。尚、ファール球回収樋６には溢れ球回収樋６Ｂが一体的に設けられている。この溢れ球回収樋６Ｂは、賞球導出樋８から賞球流入口９Ａを経て供給皿９へ導かれる賞球が一杯に詰まっている状態下に於て、表機構パネル７を開いたとき、賞球導出樋８から流下して来る賞球をパチンコ店の床等に落ちないように受け入れ、これを受皿５に戻すためのものである。【００１０】第２図〜第４図に於て、発射レール１０は、打出された打球が走行するレール本体１１と、レール本体１１を補強するための担持体１２とで構成してある。レール本体１１は、長い帯状の金属素材、例えばステンレス板の中央部分を帯状に残してレール面１３を形成し、その両側部１４、１４を下方に略直角に折曲して、全体の断面を略Ｍ型に成形してある。レール面１３には、打球が走行する長手方向の全長にわたって、打球を誘導するためのＶ字型の発射誘導溝１３ａが設けてある。【００１１】発射誘導溝１３ａは打球の下部を２点でバランスよく支える溝状の構造である。図では断面Ｖ字型の溝としてあるが、これに限らず、レール面１３内の両側に平面部が残るように、中央のみを断面Ｖ字型或いはＵ字型に成形してもよい。尚、レール本体１１の両側部１４、１４は、このレール面１３を支持し、且つその形状を保持する機能を果している。このようにレール本体１１のレール面１３に発射誘導溝１３ａを設けると、打球の走行方向を確実にコントロールでき、ガイドレール３への移動が安定するから、打球がガラスや遊技盤に接触して打球の勢が減少されるムラ飛びをなくすことができる。【００１２】次に、第５図及び第６図に於て、レール本体１１のレール面１３は、打球を滑らかにガイドレール３へ移行させるため、途中から先端側即ちガイドレール３側にかけて徐々に反り上がる曲面に成形してある。しかし、後端側即ち発射杵４側から先端側にかけて徐々に反り上がる曲面として成形してもよい。いずれにせよ、このレール面１３の走行方向の形状は、発射杵４の打撃方向及びガイドレール３の曲りとの関係で、できるだけ発射勢が減殺されない形状とするのが好ましい。レール面１３の全長を曲げる場合は、例えば半径2000mm程度の弧とするのがよい。このようにレール本体１１のレール面１３に湾曲部を設けると、打球がレール面１３から浮き上ることがなくレール面１３によく接し、発射誘導溝１３ａによるコントロールを確実に受け、安定した打球が得られるから、打球の方向づけが確実にでき発射勢の減少をなくすことができる。【００１３】第４図に於て、担持体１２は、当該担持体１２の基板表面側部分には当該部分から突出する係合部、即ち後述する係合部としての掛止部２５が設けられており、担持体の下方側部分には基板に取り付けるための延出された取付部１６が設けられている。実施例の担持体１２は、合成樹脂或いは硬質ゴムで成形されており、Ｍ型レール面１３で被われる上面部１５ａと側部１５ｂとを有する上部１５と、該上部１５の片側から下方に延在する取付部１６とからなっている。担持体１２の上部１５は、実施例では、レール本体１１の全長にわたって、その内部を内実とし一体化する長さにしてあるが、長さ方向の一区間に存在させてもよい。【００１４】又、レール面１３に形成する発射誘導溝１３ａの断面形状によっては、レール面１３の下面と担持体１２の上面部１５ａとの間に間隙を設けてもよいが、この場合でも、レール面１３の下面の一部に担持体１２の上面部１５ａが当接するように形成しておくのが補強効果の点で良い。この担持体１２は、レール本体１１の一方の側部１３側から内部の担持体１２に向けて、ネジ込んだ２つのビス２１、２２（第２図、第６図）でレール本体１１と一体化される。かように一体化することによって、レール本体１１を堅牢にすることができ、清掃時におけるレール面１３の歪みや狂いが防げる。【００１５】第５図に於て、上記２つのビス２１、２２をネジ込む目的で、レール本体１１の側部１４には、その発射杵４に近い側に１つの貫通孔１７が、またガイドレール３に近い側に複数の貫通孔１８が設けてある。貫通孔１８はこの例では、１８ａ、１８ｂ、１８ｃの３個であり、選択的に１つだけ使用される。一方、担持体１２の上部側部１５ｂには貫通孔１７に対応する止着孔１９と、複数の貫通孔１８の１つと選択的に対応する複数の止着孔２０とが設けてある。この例では止着孔２０の数も貫通孔１８と同数であり、２０ａ、２０ｂ、２０ｃの３個になっている。【００１６】第３図及び第５図から分るように、３個の止着孔２０ａ、２０ｂ、２０ｃは発射誘導方向と平行な一直線上に配列され、一方３個の貫通孔１８ａ、１８ｂ、１８ｃはこの止着孔２０の配列方向と交差する一直線上に配列されている。従って、貫通孔１７と止着孔１９を一致させてビス２１により仮り止めした後、該ビスを中心として担持体１２に対しレール本体１１を回動させることにより、異なった３つの回動位置で、貫通孔１８ａと止着孔２０ａ、貫通孔１８ｂと止着孔２０ｂ、貫通孔１８ｃと止着孔２０ｃが一致する。このうちの１つ、例えば、第６図に示すように、貫通孔１８ｂと止着孔２０ｂを一致させ、ビス２２にて止着する。【００１７】この場合、残りの貫通孔１８ａと止着孔２０ａ、貫通孔１８ｃと止着孔２０ｃとは、その位置がずれて不一致となる。レール本体１１のレール面１３の高さ位置は、貫通孔１８ｂと止着孔２０ｂを一致させて止着することにより、貫通孔１８ｂと止着孔２０ｂとを一致させた場合に比べて第６図にｘで示す量だけレール面１３を上げることができる。貫通孔１８ｃと止着孔２０ｃを一致させて止着すれば、第６図にｘで示す量だけレール面１３を上げることができる。即ち、どの貫通孔１８を選択的に使用するかにより、発射レール１０からの発射角度を調整することができる。発射レール１０が、レール本体１１と担持体１２とで構成されていることから、この発射角度調整は、発射レール１０を基板２へ取付けた後に於て行なうことができる利点を有する。【００１８】このことは、特に分離式パチンコ機に於て、遊技盤１のみを交換した際に生ずるガイドレール３と発射レール１０との相互位置の調整を容易にするものである。即ち、発射杵４により打出された打球を、その発射勢を減少させることなく、確実にガイドレール３に移動することができるよう微調整することができ、従って打球発射装置の操作部４Ａの操作保持力を大きくしなくても、遊技内部への正確な飛びを保証するものである。尚、この発射角度調整用のビス２２は、同時にレール本体１１を担持体１２に取付けるネジとしても機能するから、部品点数が少なくて済む。【００１９】第３図及び第４図に於て、基板２に対する発射レール１０の取付位置を定めるため、基板２の表面側には位置決め用突起２３が、また担持体１２の背面側の上部側部１５ｂには該突起と係合する嵌合孔２４が設けてある。更に、担持体１２の背面側の上部側部１５ｂには、係合部として、上向きに突出させたＬ字状の２つの係合部（掛止部２５）が設けてあり、この担持体１２の係合部（掛止部２５）に対応して当該係合部が係止される係止部として、基板２にはＬ字状の掛止部２５が斜め状態で通る細長い２つの貫通孔２６が設けられている。係止部としての細長い２つの貫通孔２６の配向方向は、ほぼガイドレール３の始端の接線方向となっている。【００２０】発射レール１０の担持体１２を基板２に取付けるに際しては、まず上記Ｌ字状の掛止部２５を基板２に対して斜めに立てた状態にして、これを基板２の係止部即ち貫通孔２６に挿入させてから、位置決め用突起２３に嵌合孔２４を嵌合させ、次いで担持体１２の板状の取付部１６を基板２に当接させる。これにより第９図に示すように、係合部即ち掛止部２５の内側面は基板２の背面に当接することになる。その後、後述する固定手段を形成する取付部材３０により、担持体１２の取付部１６を基板２に固定する。従って、掛止部２５が基板２の背面に当接する面積を多くし且つ安定した取付けをなすためには、貫通孔２６の縦幅、即ち配向方向と直角な方向の幅は、Ｌ字状の掛止部２５を斜め状態で通し得る最小幅とするのが好ましく、又、係止部２５のＬ字状の先端折曲部はできるだけ大きくするのが好ましい。【００２１】上記担持体１２の取付部１６を基板２に固定する固定手段として、取付部１６には、小径部２７ａと大径部２７ｂとを有する取付孔２７が開設してあり、また、基板２にも、この取付部１６の取付孔２７と同じ形状寸法の固定手段としての取付孔２８が同軸的に開設してある。尚、この取付作業を容易にするため、担持体１２には作業者が掴むことのできる把持部２９が形成してある。【００２２】第３図、第７図及び第８図に於て、図中の符合３０は、この取付孔２７、２８に挿通して発射レール１０の担持体１２を基板２に固定するための固定手段を取形成する付部材である。取付部材３０は、発射レール１０の取付孔２７と基板２の取付孔２８とを貫通する軸３１と、該軸３１の先端にあって軸３１の半径方向に２つ突出する係止部３２と、軸３１の後端にあって軸３１の周縁に張出す鍔部３３と、該鍔部３３に軸３１を手動で回すために形成した操作部３４とを有する（第７図及び第８図参照）。【００２３】実施例では、取付部材３０は耐久性に富む合成樹脂で一体成形してある。また、係止部３２は軸３１の先端周面から軸３１の直径方向にＴ字状に突出させ、鍔部３３は軸３１の後端側に軸３１と同軸に円盤状に形成してあり、係止部３２の長さは鍔部３３の径より若干短く、当該係止部３２と鍔部３３との軸方向の間隔は、基板２に発射レール１０を当接させた際、取付孔２７と取付孔２８との奥行に一致させてある。係止部３２の鍔部３３側の面は、取付の際に軸３１を回す回転方向に見て、基板２の裏面に係止部３２が容易に乗上げ可能な傾斜面３２ａとし、更に、当該傾斜面３２ａには、係止部３２の長さ方向に延びる凹溝３２ｂを形成してある。凹溝３２ｂは、係止部３２の長手方向の反りを防ぎ、係止部３２の基板２の裏面への圧接力を強めるために設けてある。【００２４】更にまた、取付部材３０には、軸３１の先端から小径の軸を延在させ、その先端を横Ｌ字状に内側に折り曲げて成る探査部３５が設けてある。取付時に於ては、軸３１及び係止部３２が鍔部３３により隠れてしまうが、その場合でも、この探査部３５は取付孔２７よりも小さく形成してあるので、この探査部３５を以って取付孔２７の位置をさぐるのは簡単であり、従って、係止部３２を担持体１２の取付孔２７に入れるのが容易になる。【００２５】又、基板２の裏面には、前記凹溝３２ｂの少なくとも一部に係合可能な小突起３６（第３図）を形成し、凹溝３２ｂと小突起との係合により、係止部３２のずれや緩みを防ぎ、係止部３２を確実に基板２に係止させるようにしてある。この小突起３６は、両方向に突出する係止部３２に対応するように夫々配設してもよい。発射レール１０の取付孔２７は、取付部材３０の軸３１が通過可能な小径部２７ａと、係止部３２が通過可能な大径部３２ｂとを持ち、更に鍔部３３は通過不能な大きさと形状に穿てばよい。従って、実施例に示す孔の形態に限らない。【００２６】実施例の取付孔２７の小径部３２ａは、軸３１が密接して通る円孔、大径部３２ｂは係止部３２の差渡しと同じ長さで円孔の一部を直径方向に拡張した形状であり、大径部３２ｂの長さ方向の差渡しは鍔部３３の径より小さくしてある。小径部３２ａを軸３１とほぼ同一径としたのは、軸３１と小径部３２ａとの密嵌合によって、発射レール１０のより確実な位置決めをなすためであり、大径部３２ｂを係止部３２の差渡しと同じ長さとしたのは、取付部材３０を取付孔２７に嵌合した際に自然脱落しないようにするためである。【００２７】実施例では、この自然脱落を更に確実に阻止するため、係止部３２の先端に取付孔２７との抜差に支障がない程度の薄肉の小突起３２ｃを設けてある。このように、取付孔２７から自然脱落を防ぐように構成すると、一部品としての取付部材３０を常時発射レール１０と一体に取扱うことができ、取付作業や部品管理の上で便利である。【００２８】基板２の固定手段としての取付孔２８は取付孔２７と同形にしてあるが、係止部３２のための大径部は、係止部３２が楽に通るよう若干大きめに形成してもよい。但し、取付孔２８の小径部は、位置決め機能を発揮させるため、軸３１と同径とするのが好ましい。実施例の場合には、基板２側の位置決め用突起２３と発射レール１０側の嵌合孔２４とで位置決めしており、更に、発射レール１０の上部に設けた掛止部２５を基板の貫通孔２６に掛け止めて固定しているため、必ずしも、同径とする必要はない。【００２９】発射レール１０の担持体１２を基板２に取付けるに際しては、先ず、上記Ｌ字状の掛止部２５を基板２の貫通孔２６に挿入させると共に、位置決め用突起２３に嵌合孔２４を嵌合させつつ、担持体１２の板状の取付部１６を基板２に当接させる。これにより取付穴２７、２８の小径部及び大径部が一致する。次に、探査部３５で取付穴２７を探して、取付部材３０の係止部３２を取付穴２７、２８の大径部に通し、鍔部３３が担持体１２に取付部１６の表面に当て、取付部材３０の係止部３２が基板２の裏面に位置するように強く押込む。次いで、操作部３４を略９０度回転させ、係止部３２の溝３２ｃを基板２の裏面の小突起３６に嵌合させる。【００３０】第９図に示すように、担持体１２の係止部３２と鍔部３３との間に、取付部１６及び基板２が挟まれ、担持体１２の取付部１６が基板２に固定される。このとき掛止部２５が基板２の裏面に強く当接して、担持体１２の上方を支持する。結局、発射レール１０全体は、その上部が掛止部２５で、下部が取付部材３０で固定されるため、取付部材３０のみで固定した場合に較べ、極めて安定した状態で固定保持される。特に、長期的な使用や清掃作業によっても、レール面１３が基板２の前側に傾くことがなくなるので、レール本体１１を担持体１２と一緒に基板２にネジ止めする必要がなく、このため、ビス等の止着手段を使用せずに、取付部材３０のみで簡単に取付け取外しができる。【００３１】第１０図及び第１１図は、基板２の面に対するレール面１３の傾きを、予め正しく調整しておくための傾斜調整機構を示したものである。基板２の面に対するレール面１３の傾きが、ガイドレール３の面とずれているときは、やはり打球の勢の減少を生じ、無視できない問題となる。第１０図の傾斜調整機構は、発射レール１０の先端部付近に於て、レール本体１１及び担持体１２を貫通させ且つ先端を基板２の表面に当接させたビス３７（第１図）による。このビス３７を通す目的で、レール本体１１の側部１４にはビス３７のための貫通孔３８が、また担持体１２の上部側部１５ｂには調整用ネジ孔３９が設けてある。このビス３７の締付け力を加減することにより、第１０図に破線で示すようなレール面１３の不適正位置を実線の適正位置とするよう、僅かに微調整することができる。従って、取付当初に於て或いは使用後に於て、第１０図にずれ量ｖで示す如く適正位置から狂った場合でも、簡単にその狂いを修正することができるものである。第１１図の傾斜調整機構は、発射レール１０の後側面と基板２との間にスぺーサ４０を嵌挿したものである。このスぺーサ４０により、第１１図にずれ量ｗで示すように、発射レール１０全体を僅かに前方に取付けるように修正することができる。【００３２】第２図に戻り、発射レール１０は図の如く基板２に取付けられるが、かかる取付状態に於ては、流下するファール球が発射レール１０先端に衝突し、その衝撃によって、発射レール１０に歪みや狂いが生ずる点が問題となる。そこで、発射レール１０を構成する担持体１２の先端に、ファール球受片４１を一体に形成し、ファール球が衝突するファール球回収樋６の受口６Ａの一部を構成させてある。これによって、ファール球の衝撃からレール本体１１が保護されると共に、ファール球受片４１を合成樹脂或いは硬質ゴム製の担持体１２と一体に成形できるから、製造及び組付作業が簡単になる。【００３３】ファール球回収樋６は、基板２表面に設けた係止片４２に係合する切欠部４３Ａを一方側に有し、他方側にビス止部４３Ｂが設けてあり、切欠部４３Ａを係止片４２に差込んで一方側を係止し、他方側のビス止部４３Ｂにビスを通して基板２に装着されている。従って、ファール球回収樋６と溢れ球回収樋６Ｂは一の作業で簡単に取付けできる。尚、図中の符合４４は供給皿９の球抜樋であり、球抜樋枠４４ａと球抜樋蓋４４ｂとで構成され、供給皿９から表機構パネル７を経て導出される供給皿９からの球を受ける開口４５を備えている。又、符合４６は強化板材部４６Ａを有する球受部、４７は発射位置を示す。【００３４】【考案の効果】本考案は叙上の如く、基板に対して発射レールを、その上部側にあっては、担持体の係合部を基板の係止部に係止させ、下部側にあっては、担持体の取付部を固定手段により着脱自在に固定し、片持ち支持構造の発射レールが、垂直方向の上下２箇所の点で取り付けられる構成としているから、閉店後の清掃時の拭き取り作業等による外部圧力に対し対抗力が高められ、長期の使用によっても、発射レールの発射誘導溝を適正状態即ち、理想的な取付状態のままに維持しておくことができる。又、本考案のものは、工具を用いることなく、手軽に発射レールの取り付け・取り外しができる。従って、又、遊技店に於て、専門の作業員が居なくても発射レールの交換を迅速に行なうことができ、発射レールの故障による遊休台をなくすことができる。更には、清掃時に於て、必要とあれば、簡単に発射レールそのものを取外せばよいから、球垢を完全に拭き取ることができ、常に最良の状態を維持してムラ飛び等の不良発射をなくすことができる。[Detailed description of the device] [0001] [Industrial field of application] The present invention proposes a ball hit by a launching pestle on the surface of a board on which a game board is mounted. A launch rail mounting device for a pachinko machine in which a launch rail inside is detachably provided It is a thing. [0002] [Prior art] The launch rail of a pachinko machine is important in determining the correct trajectory of a hit ball. So, in the past, the board of the pachinko machine was designed so that the launch rail would not be displaced. On the other hand, the launch rail was fastened with screws. However, scales are likely to adhere to the launch rail, and at the game store, this scale is removed every time. However, due to the pressing force applied during this wiping work, the firing laser is It is not uncommon for crazy distortion and distortion to occur. For such launch rails, extra force is applied to the launch rail during extraction work. Do not remove it before removing it, or if it is distorted or distorted. It is necessary to replace the discharged launch rail. However, with the conventional mounting structure with screws, it is troublesome to replace at a game store. It costs. Therefore, when the launch rail is replaced during business, the pachinko machine can be used. There was an inconvenience that the time when it could not be used became long. [0003] [Problems that the device tries to solve] In view of such a problem, the present inventors have not yet known a tool, but do not need a tool. You can attach and remove the launch rail with one touch, and the launch rail of a pachinko machine A mounting device has been proposed (Japanese Utility Model Application No. 61-11094). That is, the rail body and its supporting body constitute a launch rail, and the launch rail is supported. A mounting hole is concentrically provided on the holder and the board, and the shaft of the mounting member is inserted into the mounting hole for operation.

[0006] [Action] According to the present invention, First, the firing rail (10) is attached to the substrate (2), and the engaging portion (of the carrier (12) ( 25) is locked to the locking portion (26) of the substrate (2), After that, the mounting portion (16) of the carrier (12) is attached and detached by the fixing means (28, etc.). Since it is fixed freely, Even if the firing rail (10) has a cantilevered support structure, the engaging portion (25) and the locking portion ( 26) At the time of cleaning with the firing rail fixed by locking with Even if aging due to external pressing force in use or aging is applied, the firing rail (10) The firing guide groove (13a) is always maintained in a proper state. [0007] 【Example】 Hereinafter, the present invention will be described based on embodiments. 1 and 2, the launch rail mounting device of the present invention is a pachinko machine game. A board 2 arranged under the board 1 and a launch rail 10 mounted on the front surface of the board 2. Composed of and. In this example, the board 2 is a game board mounting portion 2A as shown in FIG. It is a box-shaped frame having. The launch rail 10 cooperates with the guide rail 3 to hit the ball from the launch pestle 4 in the game area. It serves to lead to the area 1A, and between the launch rail 10 and the guide rail 3, Strike down the guide rail 3 without reaching the launched foul ball, that is, the game area 1A. An opening 6A (Fig. 2) of the foul ball collection gutter 6 that guides the ball to the tray 5 is open. . [0008] The launch rail 10 properly regulates the direction, rotation, etc. of the hit ball, and guides the hit ball. Launch guidance so that you can move on the idrail 3 in a proper and stable running state. It is one of the most important parts of a pachinko machine. That is, the launch rail 10 is properly attached and its attachment position is not stable. And, by the time the hit ball reaches the game area 1A, the resilience is reduced due to friction with the game board and other factors. The firing pestle 4 increases the energy to be given to the ball, and as a result, the ball is shot. The operating section 4A of the shooting device must be rotated more to the right, Cause people to get tired. This is the transfer of the hit ball from the launch rail 10 to the guide rail 3. This is often due to poor movement. [0009] In addition, if the mounting position is extremely wrong, from the launch rail 10 to the guide rail 3 It is because even the movement of the ball can not be moved, and the original function of the pachinko machine is lost. The foul ball collection gutter 6 is integrally provided with an overflow ball collection gutter 6B. The overflow ball collection gutter 6B is guided from the prize ball discharge gutter 8 to the supply plate 9 through the prize ball inlet 9A. When the front mechanism panel 7 is opened under the condition that the prize balls to be covered are fully packed, Accept the prize balls that come down from the prize ball outflow gutter 8 so as not to fall on the floor of the pachinko parlor. This is for returning this to the saucer 5. [0010] 2 to 4, a launch rail 10 is a rail on which a struck ball is launched. It is composed of a main body 11 and a carrier 12 for reinforcing the rail main body 11. The rail body 11 is made of a long strip of metal material, such as a stainless steel plate having a central portion. Form a rail surface 13 and bend both side portions 14, 14 downward at a substantially right angle. Then, the entire cross section is formed into a substantially M shape. The rail surface 13 guides the hit ball over the entire length in the longitudinal direction in which the hit ball travels. A V-shaped firing guide groove 13a for the purpose is provided. [0011] The launch guide groove 13a has a groove-like structure that supports the lower part of the hit ball at two points in a well-balanced manner. . In the figure, the groove has a V-shaped cross section, but the groove is not limited to this, and the groove is formed on both sides of the rail surface 13. Only the center may be molded into a V-shaped or U-shaped cross section so that the flat portion remains. Both sides 14, 14 of the rail body 11 support the rail surface 13 and It has the function of retaining its shape. When the firing guide groove 13a is provided on the rail surface 13 of the rail body 11 as described above, Is it possible to reliably control the traveling direction of the ball and to stabilize the movement to the guide rail 3? Eliminates uneven jumping in which the hitting ball contacts the glass or game board and the hitting force is reduced. You can [0012] Next, referring to FIG. 5 and FIG. 6, the rail surface 13 of the rail body 11 slides on the hit ball. In order to shift to the guide rail 3 gently, the tip side, that is, the guide rail 3 side It is formed into a curved surface that gradually warps over time. However, a curved surface that gradually rises from the rear end side, that is, the launching pestle 4 side to the front end side May be molded. In any case, the shape of the rail surface 13 in the traveling direction is The firing force is reduced as much as possible due to the impact direction of the punch 4 and the bending of the guide rail 3. It is preferable that the shape is not formed. When bending the entire length of the rail surface 13, for example, an arc with a radius of about 2000 mm should be used. Yes. When the curved surface is provided on the rail surface 13 of the rail body 11 as described above, the hit ball is hit by the rail. It does not float from the surface 13 and is in good contact with the rail surface 13, The stable control of the ball is obtained, and a stable ball can be obtained. This can be done reliably and the decrease in firing force can be eliminated. [0013] In FIG. 4, the carrier 12 has a portion corresponding to the substrate surface side portion of the carrier 12. An engaging portion projecting from, that is, a hooking portion 25 as an engaging portion described later is provided. An extension mounting portion 16 for mounting on the substrate is provided on the lower side portion of the carrier. Has been. The carrier 12 of the embodiment is made of synthetic resin or hard rubber, and has an M-type lathe. An upper portion 15 having an upper surface portion 15a and a side portion 15b covered with a ruled surface 13, and the upper portion 1 5 and a mounting portion 16 extending downward from one side. In the embodiment, the upper part 15 of the carrier 12 extends over the entire length of the rail body 11. The inside of the is solid and has a length that integrates, but it exists in one section in the length direction. Good. [0014] Also, depending on the cross-sectional shape of the launch guide groove 13a formed on the rail surface 13, the rail surface A gap may be provided between the lower surface of 13 and the upper surface 15a of the carrier 12, but in this case Even if the upper surface 15a of the carrier 12 is in contact with a part of the lower surface of the rail surface 13, It is better to form it on the point of reinforcing effect. The carrier 12 is formed from the side 13 on one side of the rail body 11 to the inside of the carrier 12. Rail body 1 with two screws 21 and 22 (Figs. 2 and 6) screwed in toward Integrated with 1. By integrating in this way, the rail body 11 can be made robust, The rail surface 13 can be prevented from being distorted or out of order during cleaning. [0015] In FIG. 5, the rail body 11 is used for the purpose of screwing the two screws 21 and 22. On the side portion 14 of the rod, one through hole 17 is provided on the side close to the launching punch 4, A plurality of through holes 18 are provided on the side close to the rule 3. In this example, there are three through holes 18 a, 18 b, and 18 c, and 1 Only one is used. On the other hand, a fastening hole 19 corresponding to the through hole 17 is formed on the upper side portion 15b of the carrier 12. A plurality of fastening holes 20 selectively corresponding to one of the plurality of through holes 18 are provided. In this example, the number of fastening holes 20 is the same as the number of through holes 18, and 20a, 20b, 20 There are 3 of c. [0016] As can be seen from FIG. 3 and FIG. 5, the three fastening holes 20a, 20b, 20c are The three through holes 18a, 18b, and 1 are arranged on a straight line parallel to the radiation guiding direction. 8c are arranged on a straight line that intersects the arrangement direction of the fastening holes 20. Therefore, after the through hole 17 and the fastening hole 19 are aligned with each other and temporarily fixed by the screw 21, , By rotating the rail main body 11 with respect to the carrier 12 about the screw , The through hole 18a and the fastening hole 20a, and the through hole 18b at the three different rotating positions. The attachment hole 20b, the through hole 18c, and the fastening hole 20c are aligned. One of these, for example For example, as shown in FIG. 6, the through hole 18b and the fastening hole 20b are aligned with each other, and And fasten. [0017] In this case, the remaining through holes 18a and the fastening holes 20a, and the through holes 18c and the fastening holes 20c. And, their positions are displaced and do not match. The height position of the rail surface 13 of the rail body 11 is defined by the through hole 18b and the fastening hole 20b. When the through holes 18b and the fastening holes 20b are aligned with each other by fixing them by matching. The rail surface 13 can be raised by an amount indicated by x in FIG. If the through holes 18c and the fastening holes 20c are aligned and fastened, the amount shown by x in FIG. 6 is obtained. The rail surface 13 can be raised. That is, depending on which through hole 18 is selectively used, the emission from the launch rail 10 You can adjust the firing angle. Since the launch rail 10 is composed of the rail body 11 and the carrier 12. , This firing angle should be adjusted after the firing rail 10 is attached to the board 2. It has the advantage that [0018] This does not occur when the game board 1 alone is replaced, especially in a separation-type pachinko machine. This facilitates adjustment of the mutual position of the guide rail 3 and the firing rail 10 . That is, the hitting ball hit by the launching pestle 4 is reduced without reducing its launching force. Fine adjustments can be made to ensure that the guide rail 3 can be moved. Even if the operation holding force of the operation unit 4A of the hitting ball launching device is not increased, It guarantees accurate flight. In addition, the screw 22 for adjusting the firing angle simultaneously attaches the rail body 11 to the carrier 12. Since it also functions as a mounting screw, the number of parts is small. [0019] In FIGS. 3 and 4, the mounting position of the launch rail 10 to the board 2 is determined. Therefore, the positioning protrusions 23 are provided on the front surface side of the substrate 2 and on the rear surface side of the carrier 12. A fitting hole 24 that engages with the protrusion is provided in the side portion 15b. Furthermore, the upper side portion 15b on the back side of the carrier 12 is projected upward as an engaging portion. Two L-shaped engaging portions (hanging portions 25) that are extended are provided. The board 2 serves as a locking portion that locks the engaging portion (engaging portion 25). Is provided with two elongated through holes 26 through which the L-shaped hooking portion 25 passes in an oblique state. There is. The orientation directions of the two elongated through holes 26 as the locking portions are substantially the same as those of the guide rail 3. It is tangential to the beginning. [0020] When attaching the carrier 12 of the launch rail 10 to the substrate 2, first, the L-shape described above is attached. The hooking portion 25 of the substrate 2 is set in an inclined state with respect to the substrate 2, That is, after being inserted into the through hole 26, the fitting hole 24 is fitted into the positioning projection 23. Then, the plate-shaped mounting portion 16 of the carrier 12 is brought into contact with the substrate 2. As a result, as shown in FIG. 9, the inner surface of the engaging portion, that is, the hooking portion 25 is the back surface of the substrate 2. It will come into contact with the surface. After that, the carrier 12 is mounted by the mounting member 30 which forms the fixing means described later. The part 16 is fixed to the substrate 2. Therefore, the area where the hooking portion 25 contacts the back surface of the substrate 2 is increased, and the mounting is stable. In order to make a mark, the vertical width of the through hole 26, that is, the width in the direction perpendicular to the orientation direction is L-shaped. It is preferable to set the minimum width that allows the hook-like hooking portion 25 to pass through in a slanting state. It is preferable that the L-shaped tip bent portion of 5 is as large as possible. [0021] As a fixing means for fixing the mounting portion 16 of the carrier 12 to the substrate 2, the mounting portion 16 Has a mounting hole 27 having a small diameter portion 27a and a large diameter portion 27b. Also, as a fixing means having the same shape and dimension as the mounting hole 27 of the mounting portion 16 on the substrate 2 as well. The mounting hole 28 is provided coaxially. It should be noted that the carrier 12 can be held by an operator in order to facilitate the mounting work. A grip portion 29 is formed. [0022] In FIG. 3, FIG. 7 and FIG. 8, the reference numeral 30 in the drawing indicates the mounting holes 27, 28. Fixing means for fixing the carrier 12 of the launch rail 10 to the substrate 2 by inserting it into the base plate. It is an attached member to be formed. The mounting member 30 penetrates the mounting hole 27 of the launch rail 10 and the mounting hole 28 of the substrate 2. Shaft 31 and a locking portion at the tip of the shaft 31 that projects two in the radial direction of the shaft 31 32, a flange 33 at the rear end of the shaft 31 and extending over the periphery of the shaft 31, and the flange 33. And an operating portion 34 formed for manually rotating the shaft 31 (see FIGS. 7 and 8). See). [0023] In the embodiment, the mounting member 30 is integrally molded with a highly durable synthetic resin. Also The locking portion 32 is projected in a T-shape from the tip peripheral surface of the shaft 31 in the diameter direction of the shaft 31, The portion 33 is formed on the rear end side of the shaft 31 coaxially with the shaft 31 in a disk shape, and The length is slightly shorter than the diameter of the collar portion 33, and the axial distance between the locking portion 32 and the collar portion 33. Is the depth of the mounting holes 27 and 28 when the firing rail 10 is brought into contact with the board 2. To match. The surface of the locking portion 32 on the side of the flange 33 is a base when viewed in the rotation direction of rotating the shaft 31 during mounting. On the back surface of the plate 2, an engaging surface 32a is formed as an inclined surface 32a on which the engaging portion 32 can easily climb up. A concave groove 32b extending in the length direction of the locking portion 32 is formed on the slope 32a. Concave The groove 32b prevents the locking portion 32 from warping in the longitudinal direction and allows the locking portion 32 to reach the back surface of the substrate 2. It is provided to increase the pressure contact force of. [0024] Furthermore, a small-diameter shaft is extended from the tip of the shaft 31 to the mounting member 30, and An exploration unit 35 is provided, which is formed by bending the end inward in a lateral L shape. At the time of mounting, the shaft 31 and the locking portion 32 are hidden by the collar portion 33. Also in this case, since the exploration portion 35 is formed smaller than the mounting hole 27, It is easy to search the position of the mounting hole 27 with the probing portion 35, and thus the locking portion It becomes easy to insert 32 into the mounting hole 27 of the carrier 12. [0025] Also, on the back surface of the substrate 2, a small projection that can be engaged with at least a part of the groove 32b. 36 (Fig. 3) is formed, and the engagement of the locking portion 32 by the engagement of the concave groove 32b and the small protrusion. The locking portion 32 is reliably locked to the substrate 2 by preventing loosening and loosening. this The small protrusions 36 may be respectively arranged so as to correspond to the locking portions 32 protruding in both directions. Yes. The mounting hole 27 of the firing rail 10 has a small diameter portion 2 through which the shaft 31 of the mounting member 30 can pass. 7a and a large diameter portion 32b through which the locking portion 32 can pass, and the collar portion 33 does not pass. All you have to do is wear it in an appropriate size and shape. Therefore, the shape of the hole is not limited to that shown in the embodiment. [0026] The small diameter portion 32a of the mounting hole 27 of the embodiment is a circular hole through which the shaft 31 closely passes, the large diameter portion 3 2b is a shape in which a part of the circular hole is expanded in the diametrical direction with the same length as the delivery of the locking portion 32. The diameter of the large diameter portion 32b is smaller than the diameter of the flange portion 33. The reason why the small diameter portion 32a has substantially the same diameter as the shaft 31 is that the shaft 31 and the small diameter portion 32a are dense. This is because the firing rail 10 can be positioned more reliably by fitting the large diameter portion. The length of 32b is the same as the length of the delivery of the locking portion 32 because the attachment member 30 has the attachment hole 27. This is to prevent it from naturally falling off when fitted to. [0027] In the embodiment, in order to more surely prevent this natural dislodgement, the tip of the locking portion 32 is attached. A small projection 32c that is thin enough not to interfere with the insertion hole 27 is provided. In this way, if it is configured so as to prevent the mounting hole 27 from falling off spontaneously, it will be a single component. The mounting member 30 can be handled integrally with the firing rail 10 at all times. It is convenient for product management. [0028] The mounting hole 28 as a fixing means of the board 2 has the same shape as the mounting hole 27, but is locked. The large diameter portion for the portion 32 may be formed slightly larger so that the locking portion 32 can easily pass through. Yes. However, the small diameter portion of the mounting hole 28 is the same as the shaft 31 in order to exert the positioning function. The diameter is preferable. In the case of the embodiment, the positioning projection 23 on the board 2 side and the fitting on the firing rail 10 side are fitted together. It is positioned with the hole 24, and further, the hooking portion 25 provided on the upper portion of the firing rail 10 Since it is fixed to the through hole 26 of the substrate by fixing it, it is not always necessary to use the same diameter. There is no. [0029] When attaching the carrier 12 of the launch rail 10 to the substrate 2, First, the L-shaped hook 25 is inserted into the through hole 26 of the substrate 2 and While fitting the fitting hole 24 into the determining projection 23, the plate-shaped mounting portion 16 of the carrier 12 is attached. Contact the substrate 2. Thereby, the small diameter portion and the large diameter portion of the mounting holes 27 and 28 are aligned. Next, the searching portion 35 is searched for the mounting hole 27, and the locking portion 32 of the mounting member 30 is mounted in the mounting hole. Through the large diameter portions of 27 and 28, the collar portion 33 is brought into contact with the carrier 12 on the surface of the mounting portion 16, It is strongly pushed so that the locking portion 32 of the mounting member 30 is located on the back surface of the substrate 2. Then, the operating portion 34 is rotated by approximately 90 degrees so that the groove 32c of the locking portion 32 is attached to the back side of the substrate 2. The small projection 36 on the surface is fitted. [0030] As shown in FIG. 9, the mounting portion 1 is provided between the locking portion 32 and the collar portion 33 of the carrier 12. 6 and the substrate 2 are sandwiched, and the mounting portion 16 of the carrier 12 is fixed to the substrate 2. This and The catching portion 25 strongly contacts the back surface of the substrate 2 to support the upper portion of the carrier 12. As a result, the firing rail 10 as a whole has the upper portion as the hook portion 25 and the lower portion as the mounting member 30. Since it is fixed with, it is extremely stable compared to the case where it is fixed only with the mounting member 30. It is fixedly held in the state. Especially, even after long-term use and cleaning work, the rail surface 13 is tilted toward the front side of the board 2. The rail body 11 together with the carrier 12 is screwed to the substrate 2 because Therefore, only the mounting member 30 can be used without using fastening means such as screws. Can be easily installed and removed. [0031] In FIGS. 10 and 11, the inclination of the rail surface 13 with respect to the surface of the board 2 is corrected in advance. This is a view showing a tilt adjusting mechanism for properly adjusting. The inclination of the rail surface 13 with respect to the surface of the substrate 2 is deviated from the surface of the guide rail 3. When this happens, the force of the hit ball also decreases, which is a problem that cannot be ignored. The tilt adjusting mechanism shown in FIG. Screw 37 (which penetrates 11 and the carrier 12 and has its tip brought into contact with the surface of the substrate 2 ( According to Fig. 1). For the purpose of passing the screw 37, the side portion 14 of the rail main body 11 is provided with a screw 37 A through hole 38 is provided, and an adjusting screw hole 39 is provided on the upper side portion 15b of the carrier 12. is there. By adjusting the tightening force of this screw 37, the broken line in FIG. Finely adjust the unsuitable position of the rail surface 13 to the proper position of the solid line. be able to. Therefore, as shown by the deviation amount v in FIG. Even if you go mad from the proper position, you can easily correct the madness. It The tilt adjusting mechanism of FIG. 11 has a space between the rear surface of the firing rail 10 and the substrate 2. The support 40 is inserted. This spacer 40 allows the launch rail 10 to move as shown by the shift amount w in FIG. The whole can be modified to be mounted slightly forward. [0032] Returning to FIG. 2, the launch rail 10 is attached to the substrate 2 as shown in the figure. In the attached state, the falling foul ball collides with the tip of the launch rail 10 and the impact As a result, there is a problem in that the firing rail 10 is distorted or deformed. Therefore, the foul ball receiving piece 41 is attached to the tip of the carrier 12 that constitutes the launch rail 10. Part of the receiving hole 6A of the foul ball recovery gutter 6 in which the foul ball collides. It is configured. This protects the rail body 11 from the impact of the foul ball, and The ball receiving piece 41 can be integrally formed with the carrier 12 made of synthetic resin or hard rubber. Therefore, the manufacturing and assembling work is simplified. [0033] The foul ball recovery gutter 6 has a cutout 43 that engages with a locking piece 42 provided on the surface of the substrate 2. A is provided on one side, and a screw stopper 43B is provided on the other side, and the notch 43A is locked. The board is inserted into the piece 42 to lock one side, and a screw is passed through the screw stop portion 43B on the other side. It is attached to 2. Therefore, the foul ball collection gutter 6 and the overflow ball collection gutter 6B can be easily installed in one operation. Wear. The reference numeral 44 in the drawing denotes a ball draining gutter of the supply tray 9, and the ball draining gutter frame 44a and the ball draining gutter lid 4 are provided. 4b, which is led from the supply tray 9 through the front mechanism panel 7 It has an opening 45 for receiving the ball. Further, the reference numeral 46 has a reinforced plate material portion 46A. A ball receiving portion, 47 indicates a firing position.
