Description

【０００１】
【発明の属する技術分野】
本発明は、外枠に対して前枠を所要の開放位置に固定可能であり、かつ、前枠に対して裏機構セット盤を所要の開放位置に固定可能である、パチンコ遊技機に適用される開放保持機構に関するものである。
【０００２】
【従来の技術】
一般的なパチンコ機をはじめ、アレンジボール機、雀球遊技機等の球使用遊技機（以下、本明細書では「パチンコ遊技機」という）では、縦長方形の外枠の開口前側に、遊技盤や裏機構セット盤を含む各種遊技用構成部材が搭載された前枠が、着脱及び開閉可能に組付られて１台単位とされる。そして、実施にあたっては、遊技店内等における設置枠台において、外枠が所定の起立傾き角度で固定保持された後に、前枠全体が組付セットされて遊技に供される。このため、外枠は、専ら前枠全体を安定に組付け保持する外郭保持枠として、大きな荷重等に充分耐え得る強度で枠組み構成される。
【０００３】
また、前枠に関しても、遊技盤や裏機構セット盤を含む各種遊技用構成部材を搭載することを考慮して、その総荷重に対する耐久強度で構成されている。そして、この前枠全体は、両枠の一側縁の上下部にそれぞれ配置された開閉連結支持手段により連結支持され、また反対側に設置された施錠手段により閉鎖位置に施錠保持される前提にあって、遊技盤の新旧交換セットや裏側の構成部材の点検・修理等に際してその都度開放される。また、前枠の裏面に横開き可能に組付けられている裏機構セット盤も同様に、裏側の構成部材の点検・修理等に際してその都度開放される。
【０００４】
【発明が解決しようとする課題】
前述したパチンコ遊技機において、前枠全体は、開閉連結支持手段により外枠に片持ち状態で連結支持されているため、前述の交換・点検時に開放された場合、その位置が不安定で変動しやすい。特に、遊技に供されている状態では、パチンコ遊技機全体が所要の傾きで設置されていることもあって、開放された前枠側に単に触れた程度でも、前枠は、閉鎖側あるいは隣接機側へ容易に変動してしまう。また、実施状態のパチンコ遊技機相互については、球貸機を介在しただけの小間隔で配列されているため、前枠の開放範囲は、隣接するパチンコ遊技機と干渉しない条件（一般的には外枠に直交するほぼ９０〜１００度位まで）が望ましいとされている。しかし現実には、前枠全体が、微小な外力や振動を受けた場合に、隣接機側へ開放変動して、遊技者の特に右手側と干渉することがあった。
【０００５】
同様に、裏機構セット盤に関しても、開閉連結支持手段により前枠に片持ち状態で連結支持されているため、裏機構セット盤の位置は非常に不安定で変動し易いところ、これまでは、裏機構セット盤の開放位置を保持するために、操作者は、自身の手や他の人の手を借りて、裏機構セット盤を押さえるか、或いは、静止位置ぴったりに裏機構セット盤を配置する必要があり、手で押さえた場合には、操作の効率性を著しく欠くと共に、裏機構セット盤の重量もかなりあるのでその負担が大きく、また、静止位置にぴったり配置する場合には、僅かな振動や触れた程度でも容易に変動してしまうという問題があった。
【０００６】
【発明が解決しようとする課題】
したがって、本発明は、前枠と裏機構セット盤の両方を所要の開放位置に拘束保持可能な開放保持機構を提供することを目的とする。
【０００７】
【課題を解決するための手段】
上記課題を解決するために提供される本発明（１）は、固定保持枠用の外枠と、この外枠の前側に片持ち形態で開閉可能に組付けられた開閉搭載枠用の前枠と、前枠の前側に片持ち形態で開閉可能に組付けられたガラス扉と、前枠裏側の収容保持枠内に着脱可能に収容セット保持される遊技盤と、前枠の裏側に片持ち形態で開閉可能に組付けられた裏機構セット盤とを備えたパチンコ遊技機に適用される開放保持機構において、前記外枠と前記前枠との間に亘り、外枠に対して前枠を所要開放位置に固定化保持するための回動変移可能な開放保持部材を掛装し、この開放保持部材の一端に形成した回動支点部を、外枠又は前枠の一方に回動可能に支持する一方、開放保持部材の他端に形成した係合固定部を、外枠又は前枠の他方に形成した係合保持部に着脱可能に係合するように構成されている第一の開放保持機構と、外枠に対して前枠が開放保持された状態で、前枠に対して裏機構セット盤を所要開放位置に固定化保持するように構成されている第二の開放保持機構とからなり、前記第二の開放保持機構は、外枠に設けられるとともに、前記裏機構セット盤の賞球タンク部材と係合して、前枠に対して前記裏機構セット盤を所要開放位置に固定化保持することを特徴とする
【０００８】
また、本発明（２）は、固定保持枠用の外枠と、この外枠の前側に片持ち形態で開閉可能に組付けられた開閉搭載枠用の前枠と、前枠の前側に片持ち形態で開閉可能に組付けられたガラス扉と、前枠裏側の収容保持枠内に着脱可能に収容セット保持される遊技盤と、前枠の裏側に片持ち形態で開閉可能に組付けられた裏機構セット盤とを備えたパチンコ遊技機に適用される開放保持機構において、前記外枠と前記前枠との間に亘り、外枠に対して前枠を所要開放位置に固定化保持するための回動変移可能な開放保持部材を掛装し、前記開放保持部材は、前枠に対して裏機構セット盤を所要開放位置に固定化保持するためのストッパ部材を、前記ストッパ部材が前記裏機構セット盤を保持できる保持位置と、前記裏機構セット盤を保持し得ない非保持位置との間で、前記開放支持部材に沿って移動させることができ、かつ、前記ストッパ部材を前記保持位置に固定できるように備えており、この開放保持部材の一端に形成した回動支点部を、外枠又は前枠の一方に回動可能に支持する一方、開放保持部材の他端に形成した係合固定部を、外枠又は前枠の他方に形成した係合保持部に着脱可能に係合するように構成されていることを特徴とする。
さらに、上述した本発明（１）において、前記第一の開放保持機構の前記係合保持部は、前記外枠又は前記前枠の２箇所の位置に形成され、前記外枠と前記前枠とのなす角を、前記２箇所の位置の各々に応じた角度にして、前記前枠を前記外枠に対して開放保持可能にした。
【０００９】
【実施例】
次に本発明に係るパチンコ遊技機の開放保持機構の好適な実施形態を図面を参照しながら説明する。なお、本実施形態では、遊技盤の遊技領域内でセーフ球とアウト球の区分発生を含むパチンコゲームを展開しうる一般的なパチンコ機を主たる例とし、同機裏側に遊技済み球（セーフ球及びアウト球）の排出処理経路や球貯留供給装置そして各種の制御基板等を備えた裏機構が装備された実施形態を示す。また、本明細書において、「正面」、「裏面」、「左」及び「右」という場合、すべて正面前方を基準とする。
【００１０】
まずパチンコ機全体の基本的構成を図１〜図４を参照して説明すると、機枠又は外郭機体として所定の縦長方形枠サイズに構成されて設置枠台（遊技島ともいう）に固定保持される外枠Ａの前側開口面域に、これに合わせた縦長方形枠サイズに構成された開閉搭載枠用の前枠Ｂが、互いの正面左側上下部に配設された開閉連結支持手段（蝶番又はヒンジ部ともいう）Ｇ−１（１００、１０１）及び正面右側内部に配設された施錠装置Ｆを利用して、開閉（片持ち左右横開き）及び着脱が可能に組付けられて閉鎖状態に保持される。そして、この前枠Ｂの各部に必要な遊技構成部材として、前枠Ｂの前側面域に合わせた方形枠サイズのガラス扉（ガラス窓ともいう）Ｄが、開閉連結支持手段Ｇ−２及び施錠装置（図示せず）を利用して開閉（片持ち左右開き）及び着脱が可能に組付けられて閉鎖状態に保持される一方、下球皿１４及び打球発射装置１５が夫々装備されている。また、上球皿４２も、開閉連結支持手段及び施錠装置（共に図示せず）を利用して、開閉（片持ち左右開き）及び着脱が可能に組付けられて閉鎖状態に保持される。また、前枠Ｂの窓口裏側に合わせた方形枠サイズの収容枠１２に対して前記遊技盤Ｃが着脱交換可能に収容セット保持されて前面の遊技領域を前記ガラス扉Ｃの正面に望ませており、前枠Ｂの裏側に前記裏機構セット盤Ｅが、開閉連結支持手段Ｇ−３（３００、３０１）及び施錠手段（掛け具１９、止め具７０）を利用して片持ち左右横開き可能に組付けられて閉鎖状態に保持されている。
【００１１】
なお、前記外枠Ａは、木材製の縦長方形枠を例示し、前記前枠Ｂと収容枠１２とは、一体に樹脂成形された前後二重枠形態を例示する。また、前記遊技盤Ｃは、収容枠１２の収容面域の内法に合わせた方形サイズで裏側から着脱されるタイプを例示し、盤前面のレール３０の内側に、各種の遊技部品（入賞成立発生する大小の入賞具や図柄表示装置を含む）と多数本の遊技釘との配置設定に基づく前記遊技領域とアウト口を構成しており、そして収容面域の周囲に配設された施錠手段（係合レバー）１７で固定保持されるようになっている。
【００１２】
前枠Ｂの開放保持機構Ｈ−１
好適に推奨される前枠の開放保持機構Ｈ−１を、図４〜図７に示す。図４のｂに示されるように、開放保持部材４００を外枠Ａの上枠杆１下に収納するためのフック部材４０１（金属製）が、上枠杆１下にねじで締付固定されている。開放保持部材４００は、図５に示されるように、フック部材４０１（図４のｂ参照）に対して開閉連結支持手段Ｇ−１寄りの、外枠Ａの上枠杆１下に固定された回動支点ねじ（回動支点部）４０２に回動可能に支持されている。開放保持部材４００の自由端４００ａは、後述の凹状の係合保持部４０３ａ又は４０３ｂと係合する係合固定部４００ｂを有する。係合固定部４００ｂは、ナット部材４００ｃ、鍔部材４００ｄ及び間軸部４００ｅ（この幅は、係合保持部４０３ａや４０３ｂの厚みより若干大きく設定される）からなり、間軸部４００ｅは、係合保持部４０３ａや４０３ｂの凹部と係脱可能である。これにより、開放保持部材４００の自由端４００ａを係合保持部４０３ａ又は４０３ｂにセットした後は、係合保持部４０３ａや４０３ｂに対しての自由端４００ａの前後の移動が制限される。開放保持部材４００の長さは、原則的に、回動支点部と係合保持部との距離に対応し、したがって、回動支点ねじ４０２と係合保持部４０３ａや４０３ｂがどこに設置されているかに依存する。また、開放保持部材４００の形状は、本実施例では、自由端４００ａ近傍で「く」の字形に曲げられているが、カーブ形等を含め、その形状は限定されない。更に、材質に関しても、金属製が好ましいものとして挙げられるが、十分な強度を有する限り、その他の材質でもよい。
【００１３】
係合保持部４０３ａ及び４０３ｂが形成された係合保持金具４０３は、前枠Ａに対する裏機構セット盤Ｅの開閉に干渉しないような、枠体１１の上枠杆１１ａの裏面の適当な位置に、ねじ等の手段により付設されている。本実施例においては、上枠杆１１ａの裏面上部に一体形成された凹部１１ｄ内に、係合保持金具４０３が付設されている。このような構成を採れば、非使用時に開放保持機構は邪魔にならない。
【００１４】
前枠の開放保持機構Ｈ−１において、開放した前枠Ｂを所望位置に保持する場合には、開放保持部材４００を回動させて、間軸部４００ｅを係合保持部４０３ａ又は４０３ｂ中に挿嵌し、係合固定部４００ｂと係合保持部４０３ａ又は４０３ｂとを係合させる。これにより、開放保持部材４００は外枠Ａと前枠Ｂとの間に係るストッパー部材として機能し、前枠Ｂは、所望位置（４０３ａに挿嵌させた場合は前枠に対して９０度の位置、図５の実線参照；４０３ｂに挿嵌させた場合は前枠に対して１００度の位置、図５の想像線参照）で拘束（ロック）され、安定に保持される（図４のｂ参照）。なお、前枠Ｂに対する拘束の解除は、係合固定部４００ｂを係合保持部４０３ａ又は４０３ｂから嵌脱させ、開放保持部材４００を元位置まで回動させることにより行われる。
【００１５】
回動支点部及び係合保持部の設置位置に関しては、開放保持機構Ｈ−１、前枠及び外枠の破損防止の観点から、いずれも開閉連結支持手段Ｇ−１上やその近傍（好適には５ｃｍ以内）に設けられていないことが好ましい。開閉連結支持手段Ｇ−１上やその近傍に設置されている場合には、前枠Ｂによる押圧（時として引張力）が非常に大きいため、開放支持部Ｇ−１やこの部品が付設された前枠・外枠の部分破壊が生じるからである。なお、本実施例においては、回動支点部が外枠側に設けられ、係合保持部が前枠側に設けられているが、その逆も可能である。
【００１６】
また、変更例として、裏機構セット盤Ｅを固定するための掛け具（上記例では、掛け具１９ａ）と開放保持機構Ｈ−１の係合保持金具（上記例では、係合保持金具４０３）とを一体化させた態様を示す。このような構成を採ることにより、部品点数が減り、製造効率が向上する。図８に示されるように、台座１１ｂにねじで締付固定された掛け具兼係合保持金具４０４は、閉鎖状態（前枠Ｂに対して裏機構セット盤Ｅが閉じた状態）において止め具７０ａ′と係合可能な掛け具部４０４ａと、開放保持部材４００の自由端４００ａが係脱可能な係合保持部４０４ｂとを有する。なお、前枠Ｂのロック状態における裏機構セット盤Ｅの開閉を担保するため、掛け具兼係合保持金具４０４は、前枠Ｂのロック状態において、開放保持部材４００が、止め具７０ａ′の回動や裏機構セット盤の開閉に干渉しないような位置や構造にする必要がある。このような構成を採ることにより、前枠Ｂがロックされている状況下でも、前枠Ｂに対する裏機構セット盤Ｅの固定を解除でき、かつ、裏機構セット盤Ｅの開閉が可能となる。
【００１７】
また、更なる変更例として、異なった形状の係合保持金具を図１２に示す。係合保持金具４０５は、開放保持部材４００の間軸部４００ｅが挿通可能な開口部４０５ａと、間軸部４００ｅがその両端（４０５ｃ、４０５ｄ）に移動可能な横長孔４０５ｂを有する。開口部４００ｅから挿入された開放保持部材の間軸部４００ｅは、レールとして機能する横長孔４０５ｂの内周面に沿って、第一の位置４０５ｃ及び第二の位置４０５ｄに移動可能である。そして、第一の位置４０５ｃ及び第二の位置４０５ｄにおいては、開放保持部材４００のナット部材４００ｃ又は鍔部材４００ｄが、係合保持金具４０５の横長孔４０５周辺部と当接することにより、開放保持部材は、第一の位置４０５ｂ及び第二の位置４０５ｃに固定される。このような構成を採ることにより、複数の掛け部としての機能を一部材が有することになるので、部品点数が減り製造効率が向上する。
【００１８】
更なる変更例として、開放保持部材が長手方向（左右方向）に移動可能な態様を図１０及び図１１に示す。まず、外枠Ａの上枠杆１の底面上にネジで締付固定されているレール４０６は、空隙４０７を長手方向に有している。開放保持部材４０８は、レール４０６の底面長手方向に設けられた開口部４０９を介して、空隙４０７内に収納されている可動回動支点部材４１０と結合している。なお、開放保持部材４０８の軸径は、開口部４０９よりも小さく設定されており、また、可動回動支点部材４１０の幅は、空隙４０７の幅より小さく開口部４０９の幅より大きく設定されている。前枠の開放保持の際には、図１０に示されるように、開放保持部材４０８を手前に引き出し、図中右端まで可動回動支点部材４１０を移動させ、その場所を中心として、開放保持部材４０８を回動させ（図中の想像線）、前枠Ｂに設けられた係合保持部にその自由端を係止させる。このような構成を採ることにより、長い開放支持部材の収納も可能となる。なお、この態様に関しては、前枠の開放保持機構Ｈ−１に限られず、ガラス扉の開放保持機構Ｈ−２や裏機構セット盤の開放保持機構Ｈ−３にも適用可能である。
【００１９】
ガラス扉Ｄの開放保持機構Ｈ−２
好適に推奨されるガラス扉Ｄの開放保持機構Ｈ−２も、前枠Ｂの開放保持機構Ｈ−１同様、ガラス扉Ｄの開放状態において前枠Ｂとガラス扉Ｄとの間にストッパー部材としての開放保持部材を介在させるという原理を採用している。以下、図１５及び図１６を参照しながら具体的に説明する。まず、ストッパー部材としての開放保持部材５００は、枠体１１正面に形成された長手窪み部２０に埋設された杆状収納部材（金属製）５０２内で、回動支点ねじ５０３により回動可能にその一端が支持されている（これについては後述する）。開放保持部材５００の自由端５００ａは、孔状の係止口５００ｂを有しており、その孔径は、後述の係合保持部４５（４５ａ、４５ｂ）がその中を貫通するのに十分なサイズが設定されている。開放保持部材５００の長さは、回動支点部と係合保持部との距離に対応し、したがって、回動支点ねじ５０３と係合保持部４５がどこに設置されているかに依存する。また、開放保持部材５００の形状は、本実施例では、直線状であるが、カーブ形等を含め、その形状は限定されない。更に、材質に関しても、金属製が好ましいものとして挙げられるが、十分な強度を有する限り、その他の材質でもよい。
【００２０】
開放保持部材５００の自由端５００ａの係止口５００ｂに貫入可能な係合保持部４５ａ及び４５ｂは、ガラス受け枠４１ａの上方位置に、ガラス扉Ｄの補強板４１と一体的に形成されている。
【００２１】
通常時、即ちガラス扉の閉鎖状態時では、図９に示されるように、開放保持部材５００は、杆状収納部材５０２内に収納されている。このように構成すれば、非使用時に開放保持部材が邪魔になることはない。なお、開放の際には、杆状収納部材５０２から開放保持部材５００を取出す必要があるところ、この操作を容易にするために、開放保持部材５００の後ろに指を差し込めるような空間５０４が設けられている。これにより、開放保持部材を容易に引き出すことができる。
【００２２】
このような機構Ｈ−２において、開放したガラス扉Ｄを所望位置に保持する場合には、開放保持部材５００を回動支点ねじ５０３を回動軸として回動させて、係止口５００ｂを係合保持部４５ａ又は４５ｂに差込む。これにより、開放保持部材５００は前枠Ｂとガラス扉Ｄとの間に係るストッパー部材として機能し、ガラス扉Ｄは、所望位置（４５ａに差込ませた場合は前枠に対して９０度の位置、４５ｂに差込ませた場合は前枠に対して１００度の位置）で拘束（ロック）され、安定に保持される（図４のａ参照）。なお、ガラス扉Ｄに対する拘束の解除は、係止口５００ｂを係合保持部４５ａ又は４５ｂから抜出し、開放保持部材５００を元位置まで回動させることにより行われる。
【００２３】
回動支点部や係合保持部の設置場所に関しては、特に、前枠Ｂ側でのそれらの設置位置が、樹脂製の前枠Ｂの疲労破壊防止の観点から重要である。前枠Ｂ側に設けられたこれらのいずれか（本実施例においては、回動支点部である回動支点ねじ５０３）の位置は、ガラス扉Ｄの開閉連結支持手段（Ｇ−２）非近傍部であることが必要である。ここで、開閉連結支持手段（Ｇ−２）非近傍部とは、好適には、開閉連結支持手段Ｇ−２から５ｃｍ以上離れた場所を指す。他方、ガラス枠側でのこれらのいずれか（本実施例においては、係合保持部４５ａや４５ｂ）の位置も、開閉連結支持手段Ｇ−２非近傍であることが好適であるが、必ずしも開閉連結支持手段Ｇ−２非近傍である必要はない。変更例として、図１５及び図１６中に想像線として示された係合保持部４５ｃは、開閉連結支持手段Ｇ−２近傍に設けられている。この位置でガラス扉Ｄを保持することにより、係合保持部４５ａ及び４５ｂで係止させた場合には物理的に不可能であった、ガラス板の交換が可能となる。
【００２４】
本実施例の変更例として、回動支点部（回動支点ねじ）をガラス扉Ｄ側に設置し、係合保持部を前枠Ｂ側に設置する態様が挙げられる。また、回動支点部や係合保持部の大きさや形状等も、前枠Ｂやガラス扉Ｄの形状等に応じて適宜変更可能である。また、開放保持部材５００は、バネ等を利用してロック方向側へ付勢するようにしてもよく、適度の弾性変形可能な素材により成形してもよい。開放保持部材５００の形状等も適宜変更可能であり、前枠Ｂやガラス扉Ｄの形状に合わせて設定すればよい。
【００２５】
裏機構セット盤Ｅの開放保持機構Ｈ−３
裏機構セット盤Ｅの開放保持機構Ｈ−３の好適な３例を、図５、図１３、図１４及び図１７〜図１９を参照しながら説明する。まず、第一の例は、図５及び図１４に示されるように、前枠Ｂと裏機構セット盤Ｅとの間に、ストッパ部材としての開放保持部材６０２を介在させることにより、裏機構セット盤Ｅを保持するという態様である。開放保持部材６０２は、裏機構セット盤Ｅの正面の適当な位置に設けられた回動支点部（例えばねじ等）により回動可能に支持されている（図示せず）。図１４（ｂ）に示されるように、開放保持部材６０２の自由端は、孔状の係止口６０２ａを有しており、その孔径は、後述の凸部１１ｅが係止口６０２ａに貫入するのに十分なサイズに設定されている。開放保持部材６０２の長さは、回動支点部と係合保持部との距離に対応し、したがって、回動支点部と係合保持部がどこに設置されているかに依存する。また、開放保持部材６０２の形状は、本実施例では、直線状であるが、カーブ形等を含め、その形状は限定されない。更に、材質に関しても、金属製が好ましいものとして挙げられるが、十分な強度を有していればその他の材質でもよい。
【００２６】
凸部１１ｅは、前枠Ｂの上枠杆１１ａの裏上面に一体的に設けられた、裏機構セット盤の掛け具１９ａが付設された台座１１ｂ上に、一体的に設けられている。
【００２７】
第一の例において、開放した裏機構セット盤Ｅを所望位置に保持する場合には、開放保持部材６０２を回動支点部を軸として回動させて、係止口６０２ａを凸部１１ｅに貫入する。これにより、開放保持部材６０２が裏機構セット盤Ｅと前枠Ｂとの間に係るストッパー部材として機能し、裏機構セット盤Ｅは、所望位置（約８５度）で拘束（ロック）され、安定に保持される（図５の想像線参照）。なお、拘束の解除は、係止口６０２ａを凸部１１ｅから離脱させ、開放保持部材６０２を回動支点部を軸として元位置まで回動させることにより行われる。
【００２８】
回動支点部及び係合保持部の設置場所に関しては、破損防止の観点から、いずれも開閉連結支持手段Ｇ−３やその近傍（好適には、開閉連結支持手段Ｇ−３から５ｃｍ以内）に設けられていないことが好ましい。開閉連結支持手段Ｇ−３やその近傍に設置されている場合には、裏機構セット盤Ｅの重さに起因して生じる力により、開放支持部Ｇ−３やこの部品が付設された前枠Ｂ・裏機構セット盤Ｅの部分破壊が生じるからである。なお、本実施例においては、回動支点部が裏機構セット盤Ｅ側に設けられ、係合保持部が前枠Ｂ側に設けられているが、その逆も可能である。
【００２９】
第二の例は、図５及び図１３に示されるように、前枠Ｂの開放保持部材４００の周面上にストッパ部材６００を有する態様である。ストッパ部材６００は、開放保持部材４００上に回動及び移動可能に保持されている。また、ストッパ部材６００を貫通し開放保持部材４００に当接可能なネジ６０１の締め付けにより、ストッパ部材６００を所望位置・角度で固定可能である。裏機構セット盤Ｅの保持時には、ストッパ部材６００は、図１３（ｂ）に実線として例示されるように、鉛直下向きに配される。その結果、図１３（ａ）や図５に示されるように、ストッパ部材６００の自由端６００ａが、裏機構セット盤Ｅの正面と当接し、裏機構セット盤Ｅが所望の位置でストッパ部材６００により係止される。また、非保持時には、ストッパ部材６００は、図１３（ｂ）に想像線として例示されるように、その自由端６００ａが水平方向に配される。その結果、裏機構セット盤Ｅの開閉に際してのストッパ部材６００（特に自由端６００ａ）の干渉を防止できると共に、外枠Ａ内への開放保持部材４００の収納が容易となる。
【００３０】
次に、第三の例を図１７及び図１８に示す。レバー部材６０３は、先端がフック状のアーム部６０３ａと軸部６０３ｂとが一体化したものであり、ネジ６０４を軸として回動可能に支持されている。レバー部材６０３は、例えば、外枠Ａの上枠杆１の底面右側に設けられた下方に延びる部材に設置されている。レバー６０３は、回動により、外枠Ａ内に収納される位置（図示せず）と、図１７や図１８に示すような、玉タンク７２の縁がアーム部にフックされる位置とを取り得る。そして、レバー６０３が玉タンク７２の縁と係合することにより、図１７に示されるような、外枠Ａに対し裏機構セット盤Ｅが若干開いた状態を維持することができる。
【００３１】
なお、上記態様においては、レバー部材６０３と、開放保持部材４００を外枠Ａ内に保持するフック部材４０１とが別体であるが、図１９に示されるように、両者を一体化してもよい。このような構成を採ることにより、部品点数を減らすことができるので製造効率が上がる。フック兼レバー支持金具６０５は、その上部に、開放保持部材４００を外枠内に保持するフック部６０５ａを、また、その下部に、レバー６０６をねじ６０７を軸として回動可能に支持する突出部６０５ｂを有する。
【００３２】
遊技盤Ｃの脱着機構 J （レバー部材）
遊技盤Ｃの脱着機構J（レバー部材）を、図２０、図２１及び図２３を参照しながら説明する。レバー部材７００は、押出し部７００ａ、遊技盤支持部７００ｂ及びハンドル部７００ｃから構成されている。レバー部材７００は、前枠Ｂの上枠杆１１ａの裏側にネジで付設された金属製の台座７０１に、ネジ７０２により回動可能に支持されている。遊技盤Ｃが収容保持枠１２に保持されている状態においては、図２０に示されるように、レバー部材７００の遊技盤支持部７００ｂが、遊技盤Ｃが収容保持枠１２から脱着しないように、遊技盤Ｃの裏面上部を支持している。この際、レバー部材７００の押出し部７００ａは、遊技盤Ｃの前面上端と前枠Ｂの上枠杆１１ａ裏面との間の間隙３５内に位置している。また、遊技盤Ｃの保持解除状態においては、図２１に示されるように、レバー部材７００のネジ７０２を軸とした反時計回りの回動に従い、遊技盤支持部７００ｂによる遊技盤Ｃの支持が解除されると共に、押出し部７００ａにより遊技盤前面上端が押出される。このような構成を採ることにより、遊技盤の脱着が容易に行えるようになる。
【００３３】
また、変更例として挙げる、遊技盤Ｃの脱着機構（レバー部材）は、図２２及び図２４に示されるようなレバー部材７０３からなる。レバー部材７０３は、押出し部７０３ａ及びハンドル部７０３ｂから構成されている。レバー部材７０３は、前枠Ｂ上枠杆の裏側にネジで付設された金属製の台座７０４に、ネジ７０５を軸として回動可能に支持されている。遊技盤Ｃが収容保持枠１２に保持されている状態においては、図８に示されるように（実線部分）、レバー部材７０３は、台の横方向に向けられており、レバー部材７０３の押出し部７０３ａは、遊技盤Ｃの前面上端と上枠杆１１ａの裏面上端との間の間隙３５に位置している。また、遊技盤Ｃの保持解除状態においては、図８及び図２２に示されるように、ネジ７０５を軸としてのレバー部材７０３の回動に従い、押出し部７０３ａにより遊技盤Ｃの前面上部が押出される。このような構成を採ることにより、遊技盤の脱着が容易に行えるようになる。
【００３４】
遊技盤Ｃの着脱機構 J （ローラ機構）
遊技盤Ｃの着脱機構J（ローラ機構７０４）は、図２６に示されるように、ローラ部材７０４ａ（好適には金属製）と軸受金具７０４ｂとからなる。ローラ部材７０４ａは、その両端面上にそれぞれ突出する回転軸を有し、これら回転軸が、軸受金具７０４ｂの軸受上に回転可能に保持されている。ローラ機構７０４は、図３に示されるように、収容保持枠１２の下枠杆１２ｃの一部の壁がローラ機構分開放された所の真下２箇所に設置されている。詳細には、ローラ７０４ａが、回転軸を横（左右方向）にし、かつ前記開放部分から若干顔を出すように、軸受金具７０４ｂがねじにより前枠Ｂの裏面に締付固定されている。なお、ローラ７０４ａは、ローラ機構７０４が取付けられた状態においても、上部から取出し可能である。このような構成を採ることにより、遊技盤Ｃを取付ける際には、遊技盤Ｃの底部がローラ７０４ａの回動により容易にセット口内に進入し、また、遊技盤Ｃを取外す際にも、図２１に示されるように、遊技盤Ｃを後方に傾けつつ、遊技盤Ｃの底部がローラ７０４ａの回動により容易にセット口から排出される。
【００３５】
また、変更例として挙げる、遊技盤Ｃの脱着機構（ローラ機構）は、図２７及び図２８に示されるようなローラ機構７０５である。前記の例との相違点は、軸受金具７０５ｂの軸受にローラ７０５ａの軸を差込む向きが傾斜しており、したがって、取付け後は軸受からローラ７０５ａの着脱が不可能であることである。

【効果】
本発明に係る開放保持機構においては、第一に、前枠を開放した状態で開放保持部材を拘束保持方向に回動操作することにより、開放保持部材が前枠と外枠との間に係るストッパー部材として、前枠が所望位置（例えば全開位置）に拘束保持される。したがって、裏機構セット盤の裏側点検、制御基板の点検・交換、遊技盤の裏側目視点検、遊技盤の着脱、裏機構セット盤・制御基板・遊技盤の修理等が容易となる。また、本発明に係る開放保持機構の好適な態様（外枠や前枠の上辺部に開放保持部材を掛けた態様）においては、裏機構セット盤の開閉の干渉が問題とならない外枠や前枠の上辺部に設置されているため、回動支点部や係合固定部の設置位置は、基本的にはどこでもよい。したがって、この好適な態様においては、開閉連結支持手段近傍という、強度上問題があった場所に設置せざるを得なかった従来の開放保持機構と異なり、開閉連結支持手段から離れた場所（例えば、好適には開閉連結支持手段から５ｃｍ以上離れた場所）でも設置可能であるため、開放保持機構やそれが設置される前枠・外枠の破損も防止することができる。
【００３７】
第二に、本発明に係る開放保持機構によれば、前枠を開放保持した状態で、裏機構セット盤を開放保持することにより、裏機構セット盤も所望位置に拘束保持することができる。したがって、裏機構セット盤の前側点検、遊技盤の裏側点検、遊技盤の着脱、裏機構セット盤・遊技盤の修理等も容易となる。

BACKGROUND OF THE INVENTION
The present invention is applied to a pachinko gaming machine in which a front frame can be fixed to a required opening position with respect to an outer frame, and a back mechanism set board can be fixed to a required opening position with respect to the front frame. The open holding mechanism.
[0002]
[Prior art]
In general pachinko machines, game machines using balls such as arrange ball machines, sparrow ball machines, etc. (hereinafter referred to as “pachinko game machines” in this specification), the game board is located in front of the opening of the vertical rectangular outer frame. The front frame on which various game components including the rear mechanism set board are mounted is assembled so as to be detachable and openable, and is made into a unit. In implementation, after the outer frame is fixed and held at a predetermined standing inclination angle in an installation frame stand in a game store or the like, the entire front frame is assembled and set for use in the game. For this reason, the outer frame is configured with a strength that can sufficiently withstand a large load or the like as an outer frame for exclusively assembling and holding the entire front frame.
[0003]
The front frame is also configured with durability against the total load in consideration of mounting various game components including a game board and a back mechanism set board. The entire front frame is connected and supported by open / close connection support means arranged on the upper and lower portions of one side edge of both frames, and is also locked and held in the closed position by the locking means installed on the opposite side. Therefore, it is released each time a new or old replacement set of game boards or inspection / repair of components on the back side. Similarly, the back mechanism set panel mounted on the back side of the front frame so as to be able to be opened laterally is also released each time when the components on the back side are inspected and repaired.
[0004]
[Problems to be solved by the invention]
In the pachinko gaming machine described above, the entire front frame is connected and supported in a cantilevered manner to the outer frame by the open / close connection support means. Cheap. In particular, in the state where it is used for gaming, the entire pachinko gaming machine may be installed with the required inclination, so the front frame may be closed or adjacent to the open front frame side even if it is just touched. It easily fluctuates to the aircraft side. In addition, since the pachinko gaming machines in the implementation state are arranged at a small interval with the ball lending machine interposed, the open range of the front frame is a condition that does not interfere with the adjacent pachinko gaming machine (generally It is considered desirable to be approximately 90 to 100 degrees perpendicular to the outer frame. However, in reality, when the entire front frame is subjected to a minute external force or vibration, it may fluctuate to the adjacent machine side and interfere with the player's right hand side in particular.
[0005]
Similarly, since the back mechanism set panel is also connected and supported in a cantilevered state by the open / close connection support means, the position of the back mechanism set panel is very unstable and easily fluctuates. In order to maintain the open position of the back mechanism set board, the operator uses his or her hand to hold the back mechanism set board or places the back mechanism set board exactly at the stationary position. If you hold it with your hand, the efficiency of the operation will be significantly reduced, and the weight of the back mechanism set panel will be considerable, so it will be a heavy burden. There was a problem that it fluctuated easily even with a slight vibration or touch.
[0006]

[0012]
Opening holding mechanism H-1 of the front frame B
A front frame opening and holding mechanism H-1 that is preferably recommended is shown in FIGS. As shown in FIG. 4 b, a hook member 401 (made of metal) for housing the open holding member 400 under the upper frame 1 of the outer frame A is fastened and fixed with screws under the upper frame 1. ing. As shown in FIG. 5, the open holding member 400 is fixed under the upper frame 1 of the outer frame A, close to the opening / closing connection support means G- 1 with respect to the hook member 401 (see b in FIG. 4). A rotation fulcrum screw (rotation fulcrum part) 402 is rotatably supported. The free end 400a of the open holding member 400 has an engagement fixing portion 400b that engages with a concave engagement holding portion 403a or 403b described later. The engagement fixing portion 400b includes a nut member 400c, a flange member 400d, and an intermediate shaft portion 400e (this width is set to be slightly larger than the thickness of the engagement holding portions 403a and 403b). It can be engaged with and disengaged from the concave portions of the combined holding portions 403a and 403b. Thereby, after the free end 400a of the open holding member 400 is set in the engagement holding portion 403a or 403b, the movement of the free end 400a in the front-rear direction with respect to the engagement holding portion 403a or 403b is restricted. In principle, the length of the open holding member 400 corresponds to the distance between the rotation fulcrum portion and the engagement holding portion. Therefore, where the rotation fulcrum screw 402 and the engagement holding portions 403a and 403b are installed. Depends on. Further, in the present embodiment, the shape of the open holding member 400 is bent into a “<” shape in the vicinity of the free end 400 a, but the shape is not limited including a curved shape or the like. Further, regarding the material, it is preferable to use metal, but other materials may be used as long as they have sufficient strength.
[0013]
The engagement holding metal fitting 403 in which the engagement holding portions 403a and 403b are formed is at an appropriate position on the back surface of the upper frame collar 11a of the frame body 11 so as not to interfere with the opening and closing of the back mechanism set board E with respect to the front frame A. It is attached by means such as screws. In the present embodiment, the engagement holding metal fitting 403 is attached in the recess 11d integrally formed on the upper surface of the back surface of the upper frame rod 11a. If such a configuration is adopted, the open holding mechanism does not get in the way when not in use.
[0014]
When the opened front frame B is held at a desired position in the open holding mechanism H-1 for the front frame, the open holding member 400 is rotated to place the intermediate shaft portion 400e in the engagement holding portion 403a or 403b. The engagement fixing portion 400b and the engagement holding portion 403a or 403b are engaged with each other. Thereby, the open holding member 400 functions as a stopper member between the outer frame A and the front frame B, and the front frame B has a desired position (90 degrees with respect to the front frame when inserted in the 403a). Position, see solid line in FIG. 5; when inserted into 403b, it is constrained (locked) at a position of 100 degrees with respect to the front frame (see imaginary line in FIG. 5) and is stably held (b in FIG. 4) reference). The restraint on the front frame B is released by fitting / removing the engagement fixing portion 400b from the engagement holding portion 403a or 403b and rotating the open holding member 400 to the original position.
[0015]
With respect to the installation positions of the rotation fulcrum portion and the engagement holding portion, from the viewpoint of preventing damage to the open holding mechanism H-1, the front frame, and the outer frame, all are on or near the open / close connection support means G-1 (preferably Is preferably not provided within 5 cm. When it is installed on or near the open / close connection support means G-1, the pressing force (sometimes tensile force) by the front frame B is very large, so the open support part G-1 and this part are attached. This is because partial destruction of the front and outer frames occurs. In this embodiment, the rotation fulcrum portion is provided on the outer frame side and the engagement holding portion is provided on the front frame side, but the reverse is also possible.
[0016]
Further, as a modified example, a hook (in the above example, the hook 19a) for fixing the back mechanism set board E and an engagement holding metal fitting (in the above example, the engagement holding metal fitting 403) of the open holding mechanism H-1. The mode which united with is shown. By adopting such a configuration, the number of parts is reduced and the manufacturing efficiency is improved. As shown in FIG. 8, the hook / engagement holding metal fitting 404 fastened and fixed to the base 11b with a screw is a stopper in a closed state (a state in which the back mechanism set board E is closed with respect to the front frame B). 70a 'has the hook part 404a which can be engaged, and the engagement holding part 404b which the free end 400a of the open holding member 400 can engage / disengage. In order to secure the opening and closing of the back mechanism set board E in the locked state of the front frame B, the hook / engagement holding metal fitting 404 is arranged so that the open holding member 400 of the stopper 70a ′ is locked in the locked state of the front frame B. It is necessary to have a position and structure that does not interfere with rotation and opening / closing of the back mechanism set board. By adopting such a configuration, even when the front frame B is locked, the back mechanism set board E can be fixed to the front frame B, and the back mechanism set board E can be opened and closed.
[0017]
As a further modification, an engagement holding metal fitting having a different shape is shown in FIG. The engagement holding metal fitting 405 has an opening 405a through which the shaft portion 400e can be inserted, and a horizontally elongated hole 405b through which the shaft portion 400e can move at both ends (405c, 405d). The middle shaft portion 400e of the open holding member inserted from the opening portion 400e is movable to the first position 405c and the second position 405d along the inner peripheral surface of the laterally long hole 405b that functions as a rail. In the first position 405c and the second position 405d, the nut member 400c or the flange member 400d of the open holding member 400 abuts on the periphery of the laterally long hole 405 of the engagement holding metal fitting 405, thereby opening the holding member. Are fixed to the first position 405b and the second position 405c. By adopting such a configuration, since one member has a function as a plurality of hanging portions, the number of parts is reduced and manufacturing efficiency is improved.
[0018]
As a further modification, FIGS. 10 and 11 show a mode in which the open holding member is movable in the longitudinal direction (left-right direction). First, the rail 406 that is fastened and fixed on the bottom surface of the upper frame 1 of the outer frame A with a screw has a gap 407 in the longitudinal direction. The open holding member 408 is coupled to the movable rotation fulcrum member 410 accommodated in the gap 407 through an opening 409 provided in the longitudinal direction of the bottom surface of the rail 406. The shaft diameter of the open holding member 408 is set smaller than the opening 409, and the width of the movable rotation fulcrum member 410 is set smaller than the width of the gap 407 and larger than the width of the opening 409. Yes. When the front frame is held open, as shown in FIG. 10, the opening holding member 408 is pulled forward, the movable pivot fulcrum member 410 is moved to the right end in the figure, and the opening holding member is centered on that location. 408 is rotated (imaginary line in the drawing), and the free end is locked to the engagement holding portion provided in the front frame B. By adopting such a configuration, a long open support member can be accommodated. This aspect is not limited to the front frame opening and holding mechanism H-1, but can also be applied to the glass door opening and holding mechanism H-2 and the back mechanism setting panel opening and holding mechanism H-3.
[0019]
Opening holding mechanism H-2 for glass door D
The opening and holding mechanism H-2 of the glass door D that is preferably recommended is also used as a stopper member between the front frame B and the glass door D in the opened state of the glass door D, like the opening and holding mechanism H-1 of the front frame B. The principle of interposing an open holding member is adopted. Hereinafter, this will be specifically described with reference to FIGS. 15 and 16. First, the open holding member 500 as a stopper member can be rotated by a rotation fulcrum screw 503 in a bowl-shaped storage member (made of metal) 502 embedded in the longitudinal recess 20 formed on the front surface of the frame 11. One end thereof is supported (this will be described later). The free end 500a of the open holding member 500 has a hole-like locking port 500b, and the hole diameter is a size sufficient for an engagement holding portion 45 (45a, 45b) described later to penetrate therethrough. Is set. The length of the open holding member 500 corresponds to the distance between the rotation fulcrum part and the engagement holding part, and therefore depends on where the rotation fulcrum screw 503 and the engagement holding part 45 are installed. In addition, the shape of the open holding member 500 is a straight line in this embodiment, but the shape thereof is not limited including a curved shape. Further, regarding the material, it is preferable to use metal, but other materials may be used as long as they have sufficient strength.
[0020]
Engagement holding portions 45a and 45b that can be inserted into the locking port 500b of the free end 500a of the open holding member 500 are formed integrally with the reinforcing plate 41 of the glass door D at a position above the glass receiving frame 41a. .
[0021]
In a normal state, that is, when the glass door is closed, the open holding member 500 is stored in the bowl-shaped storage member 502 as shown in FIG. If comprised in this way, an open holding member will not become obstructive at the time of non-use. When opening, it is necessary to take out the opening holding member 500 from the bowl-shaped storage member 502. To facilitate this operation, there is a space 504 in which a finger can be inserted behind the opening holding member 500. Is provided. Thereby, an open holding member can be pulled out easily.
