Description

【０００１】
【発明の属する技術分野】
本発明は、パチンコ機等の遊技機に用いられる回路基板ユニットの取付構造に関する。
【０００２】
【従来の技術】
遊技機においては、遊技に必要な各種付属品のうち、パチンコ遊技の電動式チューリップや可変表示装置のような電装品の動作を制御するため、制御回路を配置した回路基板をボックスに収納して回路基板ユニットを形成し、このユニットを遊技機の裏面側に取り付けるようにしている。
【０００３】
本出願人は、このような回路基板ユニットを迅速かつ容易に着脱できると共に、取付状態では回路基板ユニットのコネクタ部を破損やゴミなどの付着から保護できる取付構造を開発した（実開平５−８６３７８号）。これは、回路基板ユニットに設けられた第１コネクタ部と、第１コネクタ部を設けた回路基板ユニットの部分を着脱自在に受け入れる装着口を有するコネクタ支持部材と、コネクタ支持部材に受け入れられた第１コネクタ部と電気的に接続する第２コネクタ部と、遊技機の裏面側にコネクタ支持部材を回動自在に取り付けるヒンジ部とを備えている。
【０００４】
この取付構造によれば、回路基板ユニットを装着する際には、第１コネクタ部を設けた回路基板ユニットの部分をコネクタ支持部材の装着口から挿入することにより、第１コネクタ部が第２コネクタ部と電気的に接続すると共に、回路基板ユニットがコネクタ支持部材に受け入れられて支持される。この結果、回路基板ユニットのコネクタ部は外部から保護されるので、損害を受けたり埃などが付着したりすることがない。
【０００５】
メンテナンス時においては、遊技機の裏側から電装品を検査したり交換したりする際、ヒンジ部を支点としてコネクタ支持部材を回動させれば、実質的に回路基板ユニットを外した状態で作業を行うことができる。更に必要であれば、コネクタ支持部材から回路基板ユニットを容易に取り外すこともできる。
【０００６】
【発明が解決しようとする課題】
しかしながら、上記の取付構造では、コネクタ支持部材やヒンジ部等の構造が複雑であるため、種々の部品が必要であり組立てが難しい。また、回路基板ユニットの着脱及び電装品の検査・交換に若干手間がかかる。
【０００７】
従って、本発明の目的は、上記のような回路基板ユニットを使用する遊技機において、より簡単な構造で、回路基板ユニットを迅速かつ容易に着脱することができるとともに電装品を容易に検査・交換することができる取付構造を有する遊技機を提供することにある。
【０００８】
【課題を解決するための手段】
本発明は、遊技機に用いられる電装品を制御するための回路基板ユニットと、該回路基板ユニットに設けられた第１コネクタ部と、該回路基板ユニットの該第１コネクタ部を設けた部分を着脱自在に受け入れる装着口を有するコネクタ支持部材と、該コネクタ支持部材に受け入れられた第１コネクタ部と電気的に接続する第２コネクタ部と、遊技機の裏面側に前記コネクタ支持部材を回動自在に取り付けるための回動支持手段とを備え、前記回動支持手段は、遊技機の裏面側において前記コネクタ支持部材を挟んで支持するように設けられた一対の支持部と、該一対の支持部に設けられた支持軸と、該支持軸を係合・離脱できるように前記コネクタ支持部材の被支持部に設けられた軸受部とで構成され、該軸受部に対して前記支持軸が係合・離脱することにより前記一対の支持部の間に前記コネクタ支持部材が着脱され、前記軸受部に前記支持軸が係合しているときに前記コネクタ支持部材が前記支持軸を支点として回動可能に支持され、前記コネクタ支持部材が遊技機の裏面に対して所定の角度となる取付位置にて、前記軸受部に対して前記支持軸が係合・離脱可能に構成し、前記コネクタ支持部材の被支持部には、前記コネクタ支持部材の回動範囲を限定するストッパーが設けられ、該ストッパーは、前記コネクタ支持部材が前記取付位置から所定量回動したとき、前記コネクタ支持部材の回動範囲を限定するとともに、前記取付位置を、限定された前記コネクタ支持部材の回動範囲外とすることを特徴とする。
【０００９】
本発明の好ましい態様によれば、前記支持軸は、前記一対の支持部から互いに向かい合うように設けられた断面小判形の突起で形成され、前記軸受部は、該突起を囲む形状の突条部から成り、該突条部の一部は、前記断面小判形の突起の短い径より僅かに広く切り欠かれた開放部となり、前記コネクタ支持部材が、前記取付位置のときに断面小判形の突起の短い径の部分が前記開放部を通過可能となることにより、前記軸受部に対して前記支持軸が係合・離脱可能となることを特徴とする。
【００１０】
また、好ましい態様では、前記開放部を形成している前記突条部の両端から、前記断面小判形の突起の嵌め込みを容易にするための端部を延出形成することが好ましい。
【００１１】
また、好ましい態様では、前記ストッパーは前記コネクタ支持部材の被支持部から突出して一体に形成され、該ストッパーと当該被支持部は共に弾性を有し、該ストッパーを当該被支持部とともに弾性変形させることによって、前記コネクタ支持部材の回動範囲の限定を解除可能とする。
【００１２】
さらに、好ましい態様によれば、前記ストッパーの一端面が基端部から先端部に向かって傾斜する傾斜面として形成され、前記ストッパーは、前記コネクタ支持部材を前記取付位置より回動させたときに前記傾斜面が前記支持部によって押圧されて、前記被支持部とともに弾性変形し、前記一対の支持部の内側に入り込む。
【００１３】
別の好ましい態様では、前記遊技機の裏面側に弾性を有する係止爪が設けられる一方、前記回路基板ユニットには該係止爪と係合する係止穴が設けられ、該係止爪が該係止穴に係合することにより前記回路基板ユニットが前記遊技機の裏面側に係止されることが好ましい。前記コネクタ支持部材の側面には、前記遊技機の電装品と前記回路基板ユニットとを電気的に接続する配線部材を納めるフック部が設けられている。
【００１４】
また、別の好ましい態様では、前記コネクタ支持部材の内部には、前記装着口から挿入された前記回路基板ユニットの先端側の面が当接し、前記第１コネクタ部が前記第２コネクタ部と電気的に接続した状態に位置付けるための位置付用内壁面が形成されている。また、別の好ましい態様では、前記コネクタ支持部材の内部には、前記装着口と反対側に位置する前記第２コネクタ部を取り付ける取付用内壁面を備え、該取付用内壁面は、上部を切り欠いた切欠き部を有するリブを形成し、該切欠き部に前記第２コネクタ部を載置して前記第２コネクタ部を取り付ける。
【００１５】
【作用及び効果】
本発明によれば、回路基板ユニットを装着する際には、コネクタ支持部材を回動支持手段に取り付けると、遊技機の裏面側でコネクタ支持部材を回動させることができる。このコネクタ支持部材の装着口から、第１コネクタ部を設けた回路基板ユニットの部分を挿入することにより、第１コネクタ部が第２コネクタ部と電気的に接続すると共に、回路基板ユニットがコネクタ支持部材に受け入れられて支持される。
【００１６】
遊技機の裏側から電装品を検査したり交換したりする際には、コネクタ支持部材を回動させれば、回路基板を実質的に外した状態で作業することができる。また、コネクタ支持部材から回路基板ユニットを容易に取り外すことができる。更に、必要に応じてコネクタ支持部材を回動支持手段から取り外すことができる。
【００１７】
従って、簡単な取付構造で回路基板ユニットを着脱することができ、電装品の検査や交換も容易にできる。また、コネクタ支持部材も回動支持手段に容易に着脱自在である。
【００１８】
本発明の好ましい態様によれば、コネクタ支持部材は、その被支持部に設けた軸受部が一対の支持部に設けた支持軸と係合することにより、一対の支持部の間に挟まれて支持され、一対の支持軸を支点として回動可能になる。また、コネクタ支持部材の軸受部から一対の支持軸を離脱させれば、コネクタ支持部材を一対の支持部の間から外すことができる。
【００１９】
支持軸を小判形の突起で形成した場合は、その小判形突起の短い径より僅かに広く切り欠かれた突条部の開放部から突起を嵌入することにより、支持軸である突起をコネクタ支持部材の軸受部に係合させることができる。
【００２０】
更に、支持軸は、ほぼ平行に延長された突条部の両端の間の開放部から挿通されることにより、突起を軸受部に係合させることを容易に達成できる。
【００２１】
また、コネクタ支持部材は、ストッパにより回動範囲が限定されるので、その回動範囲内では支持軸は軸受部から外れない。
【００２２】
更に、ストッパーは被支持部から突出して一体に形成され、ストッパーと被支持部は共に弾性を有するので、必要に応じてコネクタ支持部材を回動範囲外に回転させることができる。
【００２３】
また、ストッパーの一端面の角を面取りした場合には、コネクタ支持部材を一対の支持部に挟持させるとき、コネクタ支持部材の被支持部が容易に一対の支持部の間に入り込むので、コネクタ支持部材の装着を迅速かつ確実に行うことができる。
【００２４】
別の好ましい態様では、遊技機の裏面に弾性を有する係止爪が設けられる一方、回路基板ユニットに該係止爪と係合する係止穴が設けられているので、係止爪が係止穴に係合することにより回路基板ユニットが遊技機の裏面に確実に固定される。
【００２５】
また、コネクタ支持部材の側面に、遊技機の電装品と回路基板ユニットとを電気的に接続する配線部材を納めるフック部を設けた場合には、配線部材がコネクタ支持部材の回動の邪魔にならない。
【００２６】
【発明の実施の形態】
図１は、本発明の回路基板ユニット取付構造を使用するパチンコ遊技機の正面図であり、図２は、このパチンコ遊技機の裏面側の分解図である。
【００２７】
パチンコ遊技機１は、上部に図示しないガラス扉を有し、このガラス扉の内側にほぼ矩形の遊技盤２を備えている。遊技盤２の中央には、ガイドレール３に囲まれた円形の遊技面４が形成され、遊技者がパチンコ遊技機１の正面の右側下部に設けられた打球ハンドル５を操作すると、遊技盤２の裏側に設置した発射装置（図示せず）から遊技球が発射されてガイドレール３に沿って上昇し、遊技面４に打ち込まれるようになっている。遊技面４上には打ち出された遊技球の案内手段として多数の釘６が配置される一方、いわゆるチューリップ等を構成する複数の可変入賞装置が配置される。可変入賞装置は、遊技球の入賞に関して遊技者に不利な第１状態と遊技者に有利な第２状態とに変換される構造であり、このような可変入賞装置は公知のものである。
【００２８】
このパチンコ遊技機１は、遊技面４上に発射された遊技球が、始動口と称される入賞口に入賞することにより、別遊技が開始されるように構成されたものであり、遊技面４上には、遊技球が入ると所定個数（例えば１５個）の賞品球を払い出すように定められた一般入賞口７Ｌ，７Ｒ，７Ｃと、遊技球が入ると所定個数（例えば７個）の賞品球を払い出すと共に別遊技の始動口となるように定められた特定入賞口８Ｌ，８Ｒとを配置している。特定入賞口８Ｌ，８Ｒは、上記のような可変入賞装置から成る。
【００２９】
遊技面４の中央部には、別遊技に用いられる可変表示装置９が設けられ、その下方に、別遊技の結果が特定の表示態様になった時に開く扉を備えた変動入賞装置１０が設けられている。
【００３０】
また、遊技面４上には複数のランプ表示部１１が設けられ、この裏面側に取り付けられたランプ１２の点滅により電気的な装飾効果が得られる。
【００３１】
遊技盤２上に配置された上記付属品のうち、特定入賞口８Ｌ，８Ｒを構成する可変入賞装置、可変表示装置９、変動入賞装置１０及びランプ１２は電力を必要とする電装品であり、これらの電装品は、後述のように遊技盤２の裏面側に装着した回路基板ユニット７０（図２）から、配線基板を介して給電される。その配線基板は、図２に示すリアパネルユニット２０内に収納されている。
【００３２】
図２は、遊技盤２の裏面側の概略図である。遊技盤２の裏面には、遊技球の通路等を形成すると共に各電装品と電気的に接続した配線基板を収納したリアパネルユニット２０が、複数の止めねじ２１によって固定されている。このリアパネルユニット２０の裏面には、図１の可変表示装置９のように遊技盤２の裏側上部に突出した電装品の後部を覆う裏カバー３０が、止めねじ３１によって固定される一方、リアパネルユニット２０の裏面下部には、本発明の回路基板ユニット取付構造により、後述の回路基板ユニット７０がコネクタブラケット６４を介して取り付けられる。
【００３３】
図３は、実施例の回路基板ユニット取付構造において、コネクタブラケット６４に回路基板ユニット７０を装着する状態を示している。
【００３４】
この回路基板ユニット取付構造は、回路基板ユニット７０に設けられた第１コネクタ部６２と、回路基板ユニット７０の第１コネクタ部６２を設けた部分を着脱自在に受け入れる装着口６３を有するコネクタ支持部材であるコネクタブラケット６４と、このコネクタブラケット６４に受け入れられた第１コネクタ部６２と電気的に接続する第２コネクタ部６５と、リアパネルユニット２０の裏面側に設けられた一対のブラケット支持台５５ａ，５５ｂと、各ブラケット支持台５５ａ，５５ｂに突設されてコネクタブラケット６４を回動自在に支持する上下一対のブラケット支持部５６ａ，５６ｂとを含む。
【００３５】
コネクタブラケット６４は略長方体の箱形状に形成され、前記リアパネルユニット２０内に収納されている配線基板の延長部２２を通すための開口１０６が設けられている。第２コネクタ部６５は、コネクタブラケット６４の内壁面１４１に上下の端部をビス１０８で固定されるコネクタ支持台１４２を有し、この第２コネクタ部６５に開口１０６を通過した配線基板の延長部２２が接続されている。
【００３６】
コネクタブラケット６４の内部には、装着口６３から挿入された回路基板ユニット７０の先端側の面が当接し、第１コネクタ部６２が第２コネクタ部６５と電気的に接続した状態に位置付けるための一対の内壁面６６ａ，６６ｂが形成されている。
【００３７】
図４及び図５に示すように、これらの内壁面６６ａ，６６ｂの間にあって開口１０６と反対側に位置する内壁面１０７は、装着口６３の側から第２コネクタ部６５を取り付ける内壁面１４１に向かって傾斜している。この傾斜面１０７と開口１０６との間の内壁面１４１上には、上下方向に間隔を置いて上中下３つのリブ６７ａ，６７ｂ，６７ｃが横方向に形成され、これらの横方向リブの開口１０６側の部分６８ａ，６８ｂ，６８ｃは低く切り欠かれて、その上にコネクタ支持台１４２が載置されるようになっている。更に、上方の横リブ６７ａと内壁面６６ａとの間、及び下方の横リブ６７ｂと内壁面６６ｂとの間に、それぞれ上下方向に延びた縦リブ６９ａ及び６９ｂが形成され、上方の縦リブ６９ａの下部及び下方の縦リブ６９ｂの上部が低く切り欠かれて、その上にコネクタ支持台１４２が載置されるようになっている。そして、上方の横リブ６７ａと縦リブ６９ａとの結合部及び下方の横リブ６７ｂと縦リブ６９ｂとの結合部に、ビス１０８を入れるためのビス孔１０９が設けられている。
【００３８】
従って、上記のようにコネクタブラケット６４の内壁面１４１に形成された縦リブ６９ａ及び６９ｂの切欠き部分と横方向リブの切欠き部分６８ａ，６８ｂ，６８ｃにコネクタ支持台１４２を載置し、その上下端部にビス１０８を通してビス孔１０９にねじ込むことにより、図３に示すように第２コネクタ部６５がコネクタブラケット６４の内部の所定位置に固定される。
【００３９】
再び図３において、コネクタブラケット６４は、上記一対のブラケット支持部５６ａ，５６ｂにより、矢印Ａの方向に所定の角度範囲（この場合９０°）で回動自在に支持される。
【００４０】
回路基板ユニット７０を装着する場合には、コネクタブラケット６４を図３に示す位置（即ち、リアパネルユニット２０の背面に対してほぼ垂直な位置）に回動させ、その装着口６３から回路基板ユニット７０を矢印Ｂで示すようにコネクタブラケット６４内へ挿入する。このとき、回路基板ユニット７０は、コネクタブラケット６４の内壁面６６ａ，６６ｂに接触するまで挿入され、回路基板７０の第１コネクタ部６２がコネクタブラケット６４内の第２コネクタ部６５と電気的に接続する。これにより、回路基板ユニット７０がコネクタブラケット６４に嵌合して保持される。
【００４１】
図６は、コネクタブラケット６４をブラケット支持部５６ａ，５６ｂに取り付ける前の状態を示す。
【００４２】
上記のようにリアパネルユニット２０に突設された一対のブラケット支持部５６ａ，５６ｂの先端部には、小判形の突起から成る支持軸１４４ａ，１４４ｂが互いに向い合うように配設されている。一方、コネクタブラケット６４の一側面の両端部から張り出した一対の被支持部１４５ａ，１４５ｂには、それぞれ外側に馬蹄形状の突条部から成る軸受部１４６ａ，１４６ｂが一体に形成されると共に、各被支持部１４５ａ，１４５ｂから突出した先端部１５５ａ，１５５ｂにはストッパ１４７がそれぞれ配設されている。
【００４３】
上記軸受部１４６ａ，１４６ｂを形成している突条部は、支持軸１４４ａ，１４４ｂを形成している小判形突起を囲む形状であり、突条部の一部が小判形突起の短い径Ｒより若干広く切り欠かれて開放部１４９（幅Ｗ）となっている。また、この開放部１４９を形成する突条部の両端から、小判形突起の嵌め込みを容易にするための端部１４８，１４８’が延出形成されている。
【００４４】
取付けの際には、コネクタブラケット６４を図６の矢印で示すように移動させて、軸受部１４６ａ，１４６ｂの開放部１４９から支持軸１４４ａ，１４４ｂを嵌め込むことにより、コネクタブラケット６４がブラケット支持部５６ａ，５６ｂに支持される。
【００４５】
図７（Ａ）は、上記のようにしてリアパネルユニット２０に取り付けられたコネクタブラケット６４を下方（図６のVII で示す方向）から観た図である。図示のように、コネクタブラケット６４をリアパネルユニット２０の背面に対して所定の角度（この場合約１３０°）をとる位置まで回動させると、支持軸１４４ａ，１４４ｂが軸受部１４６ａ，１４６ｂの開放部１４９内に着脱可能な状態となる。従って、この状態で上記のようにコネクタブラケット６４をリアパネルユニット２０側に軽く押し込めば、コネクタブラケット６４は一対のブラケット支持部５６ａ，５６ｂの間に挟持される。
【００４６】
図７（Ｂ）は、（Ａ）の一部を上から見た図である。前述のようにコネクタブラケット６４の被支持部１４５ａ，１４５ｂから突出して形成されたストッパ１４７は、図７（Ａ）に示すようにコネクタブラケット６４がリアパネルユニット２０に対して所定の角度をとる位置で、ブラケット支持部５６ａ，５６ｂの縁に接触する。このストッパ１４７の接触面１４７ａは、図７（Ｃ）に示すように傾斜面として形成されている。このため、コネクタブラケット６４を、図７（Ａ）の位置から支持軸１４４ａ，１４４ｂを支点として反時計方向に回動させると、ストッパ１４７は、ブラケット支持部５６ａ，５６ｂによって押されて、被支持部１４５ａ，１４５ｂと共に弾性変形し、図８に示すように各ブラケット支持部５６ａ，５６ｂの内側に入り込む。
【００４７】
更にコネクタブラケット６４を回動させると、図９に示すようにストッパ１４７がブラケット支持部５６ａ，５６ｂの反対側の縁から突出する。これにより、弾性変形していた被支持部１４５とストッパ１４７は元の状態に戻り、ストッパ１４７の傾斜面１４７ａとは別の面１４７ｂがブラケット支持部５６の縁に当接する。このとき、コネクタブラケット６４は、リアパネルユニット２０の背面に対してほぼ垂直になる。
【００４８】
この位置で、コネクタブラケット６４は、図１０に示すようにリアパネルユニット２０の背面から９０゜の範囲で回動自在になり、この範囲外への回動は、ストッパ１４７がブラケット支持部５６に当接することで阻止される。同時に、この範囲（図中左側９０゜の範囲）においては、ブラケット支持部５６ａ，５６ｂの小判型の支持軸１４４ａ，１４４ｂが軸受部１４６ａ，１４６ｂの開放部１４９を通ることができないので、コネクタブラケット６４がコネクタ支持部５６ａ，５６ｂから外れることはない。
【００４９】
図１１は、コネクタブラケット６４に装着した回路基板ユニット７０をリアパネルユニット２０の裏面上に固定させた状態を示す（図３において下側から観た）図であり、図１２は、その回路基板ユニット７０の一端部（図１１で左側の部分）の断面図である。
【００５０】
上記リアパネルユニット２０の裏面には弾性を有する係止爪１１１が突設される一方、回路基板ユニット７０には、この係止爪１１１が係合する係止穴１１２を有する突出部１１３が突設されている。より詳細には、リアパネルユニット２０の係止爪１１１は、図１２に示すように回路基板ユニット７０の係止穴１１２に入って係合する鉤部１１１ａと、この鉤部１１１ａと反対側に突出した突起部１１１ｂとを備えている。
【００５１】
この係合構造によれば、上記のように回路基板ユニット７０をコネクタブラケット６４に装着し、コネクタブラケット６４を図１０の実線で示す位置まで回動させた時、リアパネルユニット２０上の係止爪１１１の鉤部１１１ａが回路基板ユニット７０の係止穴１１２に係合することにより、回路基板ユニット７０がリアパネルユニット２０の裏面上に係止される。この係止状態で、係止爪１１１の突起部１１１ｂを図１２の矢印方向に引く力を加えると、係止爪１１１の鉤部１１１ａが係止穴１１２から出て外れるので、回路基板ユニット７０を回動させてリアパネルユニット２０から取り外すことができる。
【００５２】
図１３は、回路基板ユニット７０に他のコネクタを接続する場合の一例を示す図である。コネクタブラケット６４の側面１５２には、コ字状のフック１５０が突設されている。この側面１５２とフック１５０とで形成される隙間１５１に配線部材であるハーネス１５３を通すことにより、コネクタブラケット６４の回動を妨げないようにしている。
【００５３】
上記実施例によれば、コネクタブラケット６４には、各ブラケット支持部５６ａ，５６ｂに突出形成された小判型の支持軸１４４ａ，１４４ｂに嵌合する軸受部１４６ａ，１４６ｂが一体に形成されているので、コネクタブラケット６４をリアパネルユニット２０に取り付ける時には、一対のブラケット支持部５６ａ，５６ｂの間にコネクタブラケット６４を嵌め込むだけでよい。これにより、取付が簡単になり、組立に要する時間を大幅に短縮することができる。
【００５４】
また、コネクタブラケット６４の軸受部１４６ａ，１４６ｂは、支持軸１４４ａ，１４４ｂの外側を略円周状に囲むことができるように、被支持部１４５ａ，１４５ｂから突出し、その突出した略円周状の一部が、小判型支持軸１４４ａ，１４４ｂの短径Ｒより僅かに大きい幅Ｗをもって開放されている。従って、コネクタブラケット６４をブラケット支持部５６ａ，５６ｂに取り付けるときには、上記幅Ｗの開放領域を支持軸１４４ａ，１４４ｂの短径部に合うようにコネクタブラケット６４を傾けて嵌め込むだけでよい。
【００５５】
更に、コネクタブラケット６４の被支持部１４５ａ，１４５ｂにはストッパー１４７が形成され、コネクタブラケット６４がリアパネルユニット２０に対して所定の範囲内のみで回動する。この回動範囲内では、小判型の支持軸１４４ａ，１４４ｂの短径Ｒの方向と軸受部１４６ａ，１４６ｂの幅Ｗの開放領域１４９とが一致せず、コネクタブラケット６４が一対のブラケット支持部５６ａ，５６ｂの間から外れないので、確実に回動可能に支持される。
【００５６】
そして、回路基板ユニット７０をコネクタブラケット６４に装着したときは、コネクタブラケット６４内で電気的に接続した２つのコネクタ部６２，６５が外部から保護されるので、破損や埃等の付着がなくなる。
【００５７】
また、回路基板ユニット７０を交換したりする場合には、コネクタブラケット６４を回動させればよく、必要に応じてコネクタブラケット６４から回路基板ユニット７０を取り外すことができる。更に、コネクタブラケット６４を回動範囲外の所定の角度に回転させれば、容易に取り外すことができる。
【００５８】
尚、上記実施例では、支持軸１４４を小判型に形成したが、短径と長径を有する形状であればよい。また、本発明の取付構造の用途は、パチンコ遊技機に限らず、スロットマシンその他の遊技機にも適用できる。
