Description

【０００１】
【発明の属する技術分野】
この発明は、複数の電気的遊技装置が配設され遊技球による遊技を提供する遊技領域を前面に備えた遊技盤と、遊技者に払い出される遊技球を排出する球排出装置や遊技に関わる電気的遊技装置を制御する制御装置を備えた裏機構盤とを具備し、上記遊技盤の裏面側に上記裏機構盤が設置されている遊技機に関する。
【０００２】
【従来の技術】
従来、遊技領域に各種入賞口や役物と呼ばれる電気的遊技装置が配設された遊技盤が遊技機本体に対し着脱自在に設置されるとともに、遊技機本体の背面側に球の排出や遊技制御など遊技に必要な各種装置が配設された裏機構盤が設置されてなるパチンコ遊技機などの遊技機が知られている。
【０００３】
裏機構盤は、ベースフレームとなる裏機構盤本体に、遊技者に供給する遊技球を貯留しておくタンク、遊技球が入賞口へ入賞した場合などにその入賞に対して所定数の賞球を排出する球排出装置、賞球排出前の遊技球を貯留するタンクから遊技球を整列させて球排出装置へ導くシュート、電気的遊技装置の制御など各種遊技制御を行う遊技制御装置（遊技制御基板）、球排出装置の排出制御を行う排出制御装置（排出制御基板）、並びに、各装置類に電源を分配する電源ユニットなどが設置されて構成される。
【０００４】
また、裏機構盤のベースフレームとなる裏機構盤本体には、中央に遊技盤の背部を臨ませる開口部が設けられているとともに、該開口部の下方には、遊技盤から流れ落ちる球（入賞球やアウト球）を集めて島設備側へと案内する回収樋や、球排出装置から排出された賞球や貸出球を遊技機前面側の排出皿まで案内する排出樋などが設けられている。
【０００５】
すなわち、従来の裏機構盤には、タンクやシュートからなる球流路、球排出装置内の球流路、回収樋や排出樋などの球流路など、上記開口部の上方、側方、下方に幾つもの球流路が設けられていた。
【０００６】
一方、裏機構盤には、球排出装置内で遊技球を移動させるモータや、タンク内に貯留された遊技球の減少を検出する半端センサ、並びに、排出樋で遊技球のオーバーフローを検出するオーバーフロー状態検出センサ、球排出装置で排出球を検出する排出球検出センサなど、数多くの電気部品が設けられており、これらと上述の制御基板とが配線を介して接続されている。また、上記の電源ユニットと各制御基板とが電源用配線を介して接続され、該電源用配線を介して各制御基板に電源が供給されている。
【０００７】
上記のように、裏機構盤にはところ狭しと多くの制御装置が取り付けられ、また、各装置の電気部品には信号線や電源線などの配線が接続されている。
【０００８】
このような状況において、従来、遊技制御基板や排出制御基板は、比較的にスペースに余裕のある上記回収樋や排出樋などの背面側に設置されるのが一般的であった。また、各電気部品に接続される配線は、裏機構盤の背部に露出させておくと作業者が引っ掛けてコネクタ抜けや切断等が発生し易いので、そのような不具合を回避するために裏機構盤の内部を配するようにするのが良い。そのため、従来よりパチンコ遊技機では、遊技制御基板や排出制御基板などの制御基板と回収樋や排出樋などの球流路との間にも配線が配設されているのが一般であった。
【０００９】
【発明が解決しようとする課題】
ところで、遊技機は、島設備等の外部装置からノイズを受けるとともに、遊技機自体からもノイズが発生することが分かっている。例えば、遊技球が球流路を流下する過程で静電気を蓄え、該静電気により電磁ノイズを発生させたり、また、複数の遊技球が離散した状態から接触した際に、遊技球間で電子が移動して特に大きな電磁ノイズを発生させたりすることがある。
【００１０】
このようなノイズが制御基板内の回路に乗ってしまうと、プログラムが暴走するなどの恐れがあったため、従来、それを防ぐためにソフト的な回避策を講じたり、また、制御基板のＧＮＤ面積を大きく取るなど、特に遊技を統括する遊技制御基板では様々なノイズ対策が施されていた。
【００１１】
しかしながら、上記制御基板と球流路との間など、ノイズが発生する球流路の近傍に配線が設けられている箇所では、ノイズが配線に乗って制御基板の回路に影響を与え、誤動作の原因となったり動作が不安定になるなどの恐れがあった。
【００１２】
このような不都合を回避するため、ノイズが配線に乗らないように、球流路の背面側に配線を配設しないようにすることも考えられるが、先にも述べたように、裏機構盤にはところ狭しと各種装置が配設されているので、球流路の背面側を避けるように配線を迂回させて配設するのは難しく、また、制御基板の背面側を通して裏機構盤の背部に浮かせるように配線を配することも考えられるが、制御基板上の電子部品が見えなくなって不正防止上問題となったり、また、先にも述べたように、配線が浮いていると遊技機の搬送時やメンテナンス時に配線を何処かに引っ掛けてコネクタ抜けや配線の切断等の不具合が発生しかねない。
【００１３】
また、例えば交流電源を供給する電源線では周囲に磁界変化等を発生させるなど、配線自身もノイズの発生源となっているため、配線で発生したノイズが配線の近傍に配設された制御基板の回路等に乗ってしまうという恐れもあった。
【００１４】
この発明は、上記実状に鑑みなされたもので、遊技機の裏機構盤に配設される配線にノイズが乗るのを防止し、且つ、該配線を整然と配設することのできる遊技機を提供することを目的としている。
【００１５】
上記課題を解決するため、請求項１記載の発明は、複数の電気的遊技装置が配設され遊技球による遊技を提供する遊技領域を前面に備えた遊技盤と、遊技者に払い出される遊技球を排出する球排出装置や遊技に関わる電気的遊技装置を制御する制御装置を裏面側に備えた裏機構盤とを具備し、上記遊技盤の裏面側に上記裏機構盤が設置されているとともに、上記裏機構盤には遊技球を通過させる球流路が設けられている一方、該球流路の背面側には遊技に必要な電圧又は信号を導く配線が配設された遊技機において、上記裏機構盤と上記制御装置との間に、上記配線を案内して固定する配線案内部が形成され且つ上記制御装置が取り付けられる制御装置取付ベースを着脱可能に介設し、上記裏機構盤の球流路と上記制御装置取付ベースとの間に、上記球流路を流下する遊技球によって発生する電磁波が上記配線に伝わらないように遮断するための板状の第１シールド手段を設けるとともに、上記制御装置取付ベースと上記制御装置との間に、上記配線からの電磁波を遮断するための板状の第２シールド手段を設け、上記裏機構盤の裏面側には、複数の嵌合ボスを形成するとともに、上記第１シールド手段には、前記嵌合ボスに対応する位置に当該嵌合用ボスが嵌合可能な第１係止孔を形成し、上記制御装置取付ベースの裏面側には、先端に上側に張り出された返し部を有する複数の係止爪と挟持用ボスとを形成するとともに、上記第２シールド手段には、前記係止爪に対応する位置に当該係止爪に掛けられる第２係止孔を形成し、上記第１シールド手段は、上記第１係止孔が上記嵌合ボスに嵌合されることで仮固定され、該状態で上記制御装置取付ベースが上記裏機構盤に止着されることで、該裏機構盤と制御装置取付ベースとの間で挟持固定され、上記第２シールド手段は、上記第２係止孔が上記係止爪に掛けられることで該係止爪の上記返し部と上記挟持用ボスとの間で挟持固定され、上記制御装置は、止着具を介して上記制御装置取付ベースの裏面側に形成される止着ボスのボス孔に止着されることで上記第２シールド手段の背面側に取り付けられている構成とした。
【００１６】
請求項２記載の発明は、請求項１記載の遊技機において、上記球流路は、上記遊技盤に送り込まれた後に入賞口に入賞或いはアウト口から回収された遊技球が通過する回収樋であり、上記裏機構盤の裏面側の上記回収樋を流下する遊技球が接触する面に沿ってゴミ掃き出し用長孔を設けるとともに、上記第１シールド手段の上記ゴミ掃き出し用長孔に対応する位置に長孔若しくは切欠きを設けたことを特徴としている。
【００３４】
【発明の実施の形態】
以下、この発明の実施の形態について、図面を参照しながら説明する。
【００３５】
図１は、本発明の実施の形態の遊技機であるパチンコ遊技機の裏面側の機構を示す裏面図である。
【００３６】
この実施の形態のパチンコ遊技機１は、図示は省略するが、正面下方に設けられた操作ダイヤルを回して、球発射装置により遊技盤上の遊技領域内に遊技球を打ち込むとともに、遊技球が遊技領域内を流下する間に遊技盤上の入賞口に入賞することで所定数の賞球が払い出される一方、入賞せずに下部中央のアウト口に流入することで遊技球が回収されると云った遊技が行われる装置である。さらに、このパチンコ遊技機１では、例えば、特定入賞口への入賞に基づき３桁の図柄が変動表示される変動表示遊技が行われ、その結果が例えば「７，７，７」のぞろ目となって大当たりが発生した場合に、電気的遊技装置としての変動入賞装置が遊技者に有利な状態に開くなど、遊技盤上で多種多様な演出の遊技が行われるようになっている。遊技盤には、上記のような遊技を行うために、変動表示遊技を行う電気的遊技装置である例えば液晶ディスプレーなどの変動表示装置や、入賞口への遊技球の投入を検出する検出器、並びに、各種装飾ランプ、変動入賞装置を駆動するモータやソレノイドなどの電気機器が、多数配設されている。
【００３７】
上記のパチンコ遊技機１の正面側には、上述の遊技盤、該遊技盤上に遊技球を発射操作するための操作ダイヤル、遊技盤上に発射する遊技球が貯留されるとともに入賞や球貸しで遊技球の払い出しが行われる排出皿の１つである供給皿（上皿とも云う）、供給皿が溢れた場合に遊技球の払い出しが行われるもう１つの排出皿である受け皿（下皿とも云う）、遊技球を貸し出す際にプリペイドカード等の有価情報が記録された遊技カードから有価情報を読み書きするＣＲユニットのカード挿入口などが設けられている。なお、上記遊技盤の前面側には遊技球が通過する遊技領域を設けてガラス板やアクリル板などの透明板が設置されている。
【００３８】
図１に示すように、このパチンコ遊技機１の裏面側には、遊技者に供給する遊技球を貯留しておくタンク１１や、遊技盤上の入賞口や上記変動入賞装置などの入賞口へ遊技球が入賞した場合にその入賞に対して所定数の賞球を排出したり球貸し要求があった場合に所定数の貸球を排出する球排出装置１２、タンク１１から遊技球を整列させて球排出装置１２へ導くシュート１３、前記変動表示装置や変動入賞装置など遊技盤に設置された種々の機器を制御する遊技制御基板を収容した遊技制御装置４０、前記球排出装置１２の動作制御を行う排出制御基板を収容した排出制御装置５０、パチンコ遊技機１が設置される島設備から供給される電源を受けて各装置類に所定電圧の動作電源を分配する電源ユニット１４、上述のＣＲユニットの本体と遊技機とを接続するためのＣＲユニット用中継基板１５、上記操作ダイヤルの操作に基づき遊技球を１個ずつ遊技領域内に打ち込む球発射装置１６、並びに、該発射装置１６の動作制御を行う発射制御装置１７などが設置されている。また、図１において、１８は遊技盤の裏面側を保護するカバーであり、該カバー１８を外すと裏機構盤本体２２（図５参照）の中央に設けられた開口部２３を介して遊技盤の背部が臨み、遊技盤に配設された変動表示装置や変動入賞装置などが背部に張り出した状態にある。
【００３９】
また、図１には示されていないが、カバー１８に覆われた遊技盤の裏面側には入賞口やアウト口に流入された遊技球を遊技盤下部の所定箇所に集める集合樋が設けられ、その下側には集合樋により集められた遊技球を回収する回収樋２５（図１１参照）が設けられている。該回収樋２５で回収された遊技球は複数のパチンコ遊技機１が設置された島設備の球補給タンクへと送られる。また、球排出装置１２の排出口１２ａ（図１６参照）から遊技盤下の供給皿および受皿までの間には排出された遊技球を案内する排出樋２８（図１６参照）が設けられている。これら集合樋や回収樋２５並びに排出樋２８が遊技球が通過する球流路となる。
【００４０】
図２には裏機構盤が組み付けられるパチンコ遊技機１のフレーム構成を示す分解斜視図を、図３にはパチンコ遊技機１の裏機構盤の裏面図を、図４には裏機構盤の斜視図を、図５には裏機構盤のベースフレームである裏機構盤本体の斜視図をそれぞれ示す。
【００４１】
上記パチンコ遊技機１の裏面側に配設される機構のうち、球発射装置１６やＣＲユニット用中継基板１５はパチンコ遊技機１のベースフレームとなる前面枠本体２０（図２参照）に直接取り付けられる。一方、タンク１１、球排出装置１２、シュート１３、遊技制御装置４０、排出制御装置５０、電源ユニット１４、発射制御装置１７などは、図５に示すフレーム状に形成された裏機構盤本体２２に取り付けられて裏機構盤１００を構成する。また、裏機構盤本体２２には、上記の回収樋２５や排出樋２８が設けられている。
【００４２】
図２に示すように、裏機構盤１００は、パチンコ遊技機１のベースフレームとなる前面枠本体２０に例えば金属フレームからなる遊技盤収納部材２１と共に止着されて取り付けられる。なお、遊技盤は上記遊技盤収納部材２１に着脱可能に取り付けられる一方、前面枠本体２０の正面側にはガラス板等の透明部材を収容した前面ガラス枠（図示略）が開閉可能な状態で取り付けられる。
【００４３】
上記のように構成される裏機構盤１００においては、図３、図４に示すように、必然的に、その上部にはタンク１１やシュート１３が配設され、中央部分には遊技盤の裏側に配設された変動表示装置や変動入賞装置などが張り出した状態にされ、中段右側には球排出装置１２が配設される。そのため、遊技制御装置４０や排出制御装置５０および電源ユニット１４等が設置できるスペースは、残りの中段左側のスペースと下段のスペースとなる。さらに、各装置間を接続する配線のしやすさ、並びに、遊技制御装置４０や排出制御装置５０および電源ユニット１４のそれぞれ大きさ等を考慮すると、電源ユニット１４は中段左のスペース、遊技制御装置４０は下段中央から左側のスペース、排出制御装置５０は下段の右側のスペースにそれぞれ配置されるのが望ましい。遊技制御装置４０が取り付けられる下段中央から左側のスペースにはその奥方に回収された遊技球が通過する回収樋２５があり、排出制御装置５０が取り付けられる下段右側のスペースにはその奥方に排出された遊技球が通過する排出樋２８がある。
【００４４】
図６には、裏機構盤１００の下段中央から左側の部分に配設された装置や部品を分離させた分解斜視図を示す。
【００４５】
裏機構盤１００の下段中央から左側の部分には、裏機構盤本体２２に設けられた回収樋２５がプラスチック製のカバーに覆われて形成されており、その背面側には、順に、電磁波遮断用の第１シールド手段８０、基板ボックス取付ベース部材７０、電磁波遮断用の第２シールド手段６０、および遊技制御装置４０が取り付けられる。
【００４６】
遊技制御装置４０は、止着具４１ａ，４１ａ（例えばワンタッチ式で且つ着脱可能な状態でボス孔に止着できるナイラッチなど）を介して基板ボックス取付ベース部材７０に取り付けられる。すなわち、遊技制御装置４０の基板ボックス４０Ａの側方に張り出して形成された止着用片４１，４１の孔に止着具４１ａ，４１ａを通し、該止着具４１ａ，４１ａを取付ベース部材７０のボス孔７１，７１に挿入して止着することで、遊技制御装置４０が取付ベース部材７０に取り付けられる。
【００４７】
図７には、裏機構盤１００から遊技制御装置４０を外して第２シールド手段６０を露出させた状態の裏面図を示す。
【００４８】
第２シールド手段６０は、例えば、鉄板などの金属等から形成された略平面状の導電性の部材であり、周縁部と中央とで段差６２を設けることで強度を低下させることなく薄くて軽量に形成されている。この第２シールド手段６０は、遊技制御装置４０の遊技機正面側すなわち基板ボックス４０Ａの底面とほぼ同一形状同一の大きさに形成されている。第２シールド手段６０には複数の係止孔６４…が設けられ、取付ベース部材７０の係止爪７３…に掛けて簡単に係止できるようになっている。そして、遊技制御装置４０が取付ベース部材７０に止着されることで、取付ベース部材７０と遊技制御装置４０との間に第２シールド手段６０が固定される。なお、導電性部材として、導電性樹脂等のほかの材質の部材を利用するようにしても良い。
【００４９】
図８は、裏機構盤１００から第２シールド手段６０を外して基板ボックス取付ベース部材７０を露出させた状態の裏面図、図９は、図８の裏機構盤１００から配線を除いた状態の裏面図である。
【００５０】
基板ボックス取付ベース部材７０は、主に、遊技制御装置４０を裏機構盤１００に取り付ける際に裏機構盤本体２２（図５）と遊技制御装置４０との間に介設されるもので、取付ベース部材７０を介して遊技制御装置４０を取り付けることで、例えば、遊技制御装置４０の大きさや形状が変わるなどしてその止着位置が変更された場合でも、裏機構盤本体２２の形状や止着部の位置を変更することなく、取付ベース部材７０の形状や止着部の位置を修正するのみで対応することが可能になっている。
【００５１】
この実施の形態の基板ボックス取付ベース部材７０は、例えば透明なアクリルなどのプラスチックにより形成され、その背面側には、遊技制御装置４０を止着するためのボス孔７１，７１が形成されたボスや、第２シールド手段６０を係止するシールド手段係止部としての係止爪７３…、該係止爪７３…との間で第２シールド手段６０を挟持固定するために張り出されたボス７４、裏機構盤本体２２に止着固定するための止着孔７２、電源線や信号線を案内する配線案内部としての配線案内用凹部７５…、配線を係止する係止片７６…などが設けられている。上記の係止爪７３…の先端部には上側に張り出された返しが形成され、第２シールド手段６０を持ち上げて引かないと第２シールド手段６０が外れないようになっている。取付ベース部材７０の遊技機正面側の面はほぼ平面的に形成されている。
【００５２】
上記取付ベース部材７０の背面側に配設される配線は、電源ユニット１４から発射制御装置１７に接続される電源線Ｌ１、電源ユニット１４から排出制御装置５０に接続される電源線Ｌ２、ＣＲユニット用中継基板用の電源線Ｌ３、遊技制御装置４０と球排出装置１２とを接続する制御線Ｌ４などである。取付ベース部材７０に設けられた配線案内用凹部７５…および係止片７６…は、上記の配線を整然と案内し係止できるように構成されている。
【００５３】
図１０には、裏機構盤１００から基板ボックス取付ベース部材７０を外して第１シールド手段８０を露出させた状態の裏面図を、図１１には裏機構盤１００の回収樋２５と第１シールド手段８０との拡大図を示す。図１１において、ＯＵＴ１は遊技領域の中央下端に設けられアウト球を回収するアウト口、Ｂは流下中の遊技球である。
【００５４】
第１シールド手段８０は、例えば、土台紙にアルミシートを張って形成した導電性部材となっており、低コストで且つ薄く軽量に形成されている。第１シールド手段８０は、裏機構盤本体２２に設けられた回収樋２５や遊技盤下側の段にある集合樋２４並びにアウト口ＯＵＴ１など、遊技球が通過する部分を覆う形状に設けられている。なお、導電性部材として、導電性樹脂等ほかの材質の部材を利用するようにしても良い。
【００５５】
なお、第１シールド手段８０の形状は、球流路を全て覆う形状ではなく、取付ベース部材７０に配線が配設される箇所を主に覆うような形状にしても良い。
【００５６】
第１シールド手段８０には係止孔８１…が設けられ、該係止孔８１…や第１シールド手段８０の側辺に裏機構盤本体２２に設けられたボス（突起部）Ｋ…が嵌合されて簡単に固定されるようになっている。そして、その背面側から取付ベース部材７０が取り付けられることで、取付ベース部材７０と裏機構盤本体２２との間に第１シールド手段８０が挟持固定されるようになっている。
【００５７】
また、図１１に示すように、回収樋２５には、遊技球が接触する面に沿って開口されたゴミ掃き出し用長孔Ｍ，Ｍが設けられており、上記第１シールド手段８０にも、これに対応する位置が開口するように同様に長孔８２又は切欠き８３が設けられている。
【００５８】
しかして、この実施の形態の裏機構盤本体２２によれば、回収樋２５や集合樋２４下部の背面に第１シールド手段８０が介設されるとともに、その背面側に取付ベース部材７０が取り付けられてその配線案内用凹部７５…に配線が配されるので、集合樋２４下部や回収樋２５を流下する複数の遊技球が接触したり離れたりする際に発生される電磁ノイズが第１シールド手段８０により遮断されて、該電磁ノイズが上記配線に乗ることを防止できる。
【００５９】
また、取付ベース部材７０に配された配線の背面側には第２シールド手段６０が介設された上で遊技制御装置４０が設置されるので、配線から発生する電磁ノイズ（例えば交流電源による電磁ノイズ）が遊技制御装置４０の制御回路に乗って悪影響を与えるといったことも防止できる。
【００６０】
図１２には、実施例の裏機構盤１００の下段右側の部分に配設された装置や部品を分離させた分解斜視図を示す。
【００６１】
裏機構盤１００の下段右側の部分には、裏機構盤本体２２に設けられた排出樋２８が露出した状態で形成されており、その背面側には、順に、排出樋２８のカバーと取付ベース部材９０の固定用ベースを兼ねた球流路カバー３０、電磁波遮断用の第１シールド手段８５、排出制御装置５０用の取付ベース部材９０、電磁波遮断用の第２シールド手段６５、および排出制御装置５０が取り付けられている。
【００６２】
排出制御装置５０の制御基板を収容する基板ボックス５０Ａにはその側方に張り出して設けられた取付片５１，５１にネジ挿通孔が設けられ、該ネジ挿通孔にネジを通して基板ボックス取り付けベース９０のネジ孔９１，９１に螺着することで、排出制御装置５０が取付ベース部材９０に取り付けられている。
【００６３】
図１３は、実施例の裏機構盤１００から排出制御装置５０を外して第２シールド手段６５を露出させた状態を示す裏面図である。
【００６４】
第２シールド手段６５は、例えば、鉄板など金属等の導電性部材を略平面状に形成した部材であり、周縁部と中央とで段差６６を設けることで強度を低下させることなく薄く且つ軽量に形成されている。この第２シールド手段６５は、排出制御装置５０の遊技機正面側すなわち基板ボックス５０Ａの底面とほぼ同一形状で同一の大きさに形成されている。第２シールド手段６５には複数の係止孔６７…が設けられており、取付ベース部材９０の係止爪９２…に掛けて簡単な固定が可能になっている。そして、排出制御装置５０が取付ベース部材９０に止着されることで、取付ベース部材９０と排出制御装置５０との間に第２シールド手段６５が固定されるようになっている。本実施形態では、第２シールド手段６５は単に固定されているだけであるが、取付ベース部材９０と排出制御装置５０との間で挟持固定されるようにしても良い。
【００６５】
図１４は、裏機構盤１００から第２シールド手段６５を外して取付ベース部材と配線を露出させた状態の裏面図である。
【００６６】
基板ボックス取付ベース部材９０は、排出制御装置５０を裏機構盤１００に取り付けるためのベース部材であり、該取付ベース部材９０を介して排出制御装置５０を取り付けることで、例えば、排出制御装置５０の大きさや形状が変わるなどしてその止着位置が変更された場合でも、裏機構盤本体２２の形状や止着部の位置を変更することなく、取付ベース部材９０の形状や止着部の位置を修正するのみで対応することが出来る。
【００６７】
この実施の形態の基板ボックス取付ベース部材９０は、例えば透明アクリルなどのプラスチックにより形成され、その背面側には、排出制御装置５０を止着するためのボスとネジ孔９１，９１、第２シールド手段６５を係止するシールド手段係止部としての係止爪９２…、電源線や信号線を案内する配線案内部としての配線案内用凹部９３…、配線を係止する係止片９４…などが設けられている。上記の係止爪９２…の先端部には上側に張り出された返しが設けられ、第２シールド手段６５を持ち上げて引かないと第２シールド手段６５が外れないようになっている。
【００６８】
上記取付ベース部材９０の背面側に案内される配線は、電源ユニット１４から排出制御装置５０に供給される電源の電源線Ｌ２、ＣＲユニット用中継基板用の電源線Ｌ３、遊技制御装置４０と球排出装置１２とを接続する制御線Ｌ４、球排出装置１２と排出制御装置５０とを接続する制御線Ｌ５などである。取付ベース部材９０に設けられた配線案内用凹部９３…および係止片９４…は、上記の配線を整然と案内し係止できるように形成されている。
【００６９】
図１５は、裏機構盤１００から取付ベース部材９０を外して第１シールド手段８５を露出させた状態の裏面図である。同図において、第１シールド手段８５は斜線を付して示している。また、図１６は、裏機構盤１００の排出樋２８と第１シールド手段８５との関係を示す拡大図である。同図において、ＯＵＴ２は供給皿への排出口、ＮとＳＷは遊技球が受皿でも溢れたことを検出するための可動片とオーバーフロースイッチである。
【００７０】
第１シールド手段８５は、例えば、土台紙にアルミシートを張って形成した導電性部材からなるもので、低コストで且つ薄くて軽量に形成される。第１シールド手段８５には複数の係止孔８６，８６が設けられ、該係止孔８６，８６に球流路カバー３０のボスＫ，Ｋが挿通されることで仮固定され、その背面側から取付ベース部材９０が止着されることで、取付ベース部材９０と球流路カバー３０との間に第１シールド手段８５が挟持固定されるようになっている。球流路カバー３０は球流路を覆う面部と反りを防ぐ桟３２…とを有しているが、この桟３２…に囲まれる１つの凹部内に第１シールド手段８５が挿入されるようになっている。
【００７１】
図１６に示すように、この第１シールド手段８５は、排出樋２８に囲まれた球流路の全てを覆うようには形成されておらず、その背面側に配線が配設される部分を主に覆うように形成されている。
【００７２】
しかして、この実施の形態の裏機構盤本体２２によれば、排出樋２８の背面で配線が配される範囲に第１シールド手段８５が介設されるとともに、この第１シールド手段８５の背面側に取付ベース部材が取り付けられてその配線案内用凹部９３に配線が配設されるので、球排出装置１２から排出樋２８を流下する遊技球が接触したり離れたりすることで発生される電磁ノイズを第１シールド手段８５により遮断して、該電磁ノイズが配線に乗ることを防止できる。
【００７３】
また、取付ベース部材９０に配設された配線の背面側には第２シールド手段６５が介設され、その上で排出制御装置５０が設置されるので、配線から発生する電磁ノイズが排出制御装置５０の制御回路に乗って悪影響を及ぼすといったことも防止できる。
【００７４】
以上のように、この実施の形態のパチンコ遊技機１によれば、第１シールド手段８０，８５の電磁シールドにより、回収樋２５や排出樋２８などの球流路で発生された電磁ノイズがその背面側に配設された電気配線に乗ってしまうのを防止し、延いては、該ノイズが配線を介して各装置の電気回路に伝わり悪影響を及ぼすといったことを防止できる。
【００７５】
また、第１シールド手段８０，８５の背面側、具体的には、基板ボックス取付ベース部材７０，９０の背面部に、配線を収容し案内する凹形状に形成された配線案内部７５…，９３…と、案内された配線を係止する係止片７６…，９４…とが設けられているので、多数の装置が入り組んだ状態で配設される裏機構盤１００において、球流路で発生する電磁ノイズが配線に悪影響を及ぼさないようにした上で、配線を整然と配設することが出来る。
【００７６】
また、第１シールド手段８０，８５の背面側に配設された配線の更に背面側に、電磁波を遮断するための第２シールド手段６０、６５を設けたので、これらの配線から発生する電磁ノイズ（例えば交流電源やパルス信号による電磁ノイズ）が、その背面側に設置される電気回路や電気的な装置（具体的には遊技制御装置４０や排出制御装置５０）に悪影響を及ぼすことを防止できる。
【００７７】
また、回収樋２５や排出樋２８などに囲まれた球流路とその背面側に設置される遊技制御装置４０や排出制御装置５０などの機器との間に配線を収容しているので、配線や機器に及ぼされる電磁ノイズの影響を除去した上で、見た目上配線が隠れて好ましいし、また、配線が遊技機の背部に飛び出さないので、パチンコ遊技機１の搬送時や設置時、並びにメンテナンス時などに、配線が作業者に引っ掛かってしまうと云った不都合を防止できる。
【００７８】
また、基板ボックス取付ベース部材７０，９０に第２シールド手段６０，６５を係止する係止爪７３…，９２…を設けたので、基板ボックス取付ベース部材７０，９０が、基板ボックス４０Ａ，５０Ａの取付け用ベースと、配線案内部と、第２シールド手段６０，６５の固定部とを兼ねた構成となり、パチンコ遊技機１の部品点数の削減と組付工程の削減を図ることが出来る。
【００７９】
また、遊技制御装置４０や排出制御装置５０を裏機構盤本体２２に直接取り付けずに、裏機構盤本体２２から分離できる基板ボックス取付ベース部材７０，９０を介して取り付けているので、例えば制御装置の基板ボックス４０Ａ，５０Ａの形状や大きさが変化して、それを裏機構盤１００に取り付けるための止着位置等が変化しても、裏機構盤本体２２の変更を伴わずに基板ボックス取付ベース部材７０，９０の変更のみで基板ボックス４０Ａ，５０Ａの取付けが可能となる。従って、例えば、第１種や第２種などの異なる遊技機種間でも、裏機構盤本体２２を共通にすることが可能であり、それによりパチンコ遊技機１の製造コストの低減を図ることが出来る。同様に、第２シールド手段６０，６５の大きさや形状が変化して、その固定部の位置が変化しても、基板ボックス取付ベース部材７０，９０の変更のみで対応することが出来る。
【００８０】
また、基板ボックス取付ベース部材７０，９０の背面側に配線案内部が設けられているので、基板ボックス４０Ａ，５０Ａと第２シールド手段６０，６５を取り外すことで、隠れていた配線が露出され、配線の視認が行いやすいし、また、配線や第２シールド手段６０，６５および基板ボックス４０Ａ，５０Ａの組み付けも容易なものとなる。
【００８１】
また、第２シールド手段６０と基板ボックス４０Ａとが分離した状態で裏機構盤１００に取り付けられているので、例えば、遊技盤や遊技制御装置４０を交換して新たな機種替えを行う場合に、第２シールド手段６０は交換せずにそのまま流用することができる。従って、パチンコ遊技機１の運用コストの低減が図れる。
【００８２】
なお、本発明の遊技機は、この実施の形態のパチンコ遊技機１に限られず、発明の趣旨を逸脱しない範囲で適宜変更可能である。
【００８３】
例えば、本発明は第１種や第２種などのパチンコ遊技機のほか、アレンジボール遊技機など、遊技球を使用するもので、裏機構盤に遊技球を通過させる球流路が設けられている全ての遊技機に適用することができる。
【００８４】
また、第１シールド手段は、実施の形態の回収樋２５や排出樋２８の背面側に設置するほか、例えば遊技盤裏の集合樋の背面側、供給皿から球発射装置の発射位置まで遊技球が送られる球流路の背面側、球発射装置により打ち込まれる遊技球が通過する球流路の背面側など、背面側に配線が配設される球流路であればその間に設置することで同様の効果が得られる。
【００８５】
また、上記実施の形態では、第１シールド手段と基板ボックス取付ベース部材とを別体の構成としたが、基板ボックス取付ベース部材の遊技機正面側の面に第１シールド手段を固着して、第１シールド手段と基板ボックス取付ベース部材とを一体的に構成しても良い。このような構成によれば、組み立て時やメンテナンス時において第１シールド手段の取扱いが省けて作業性が向上する。
【００８６】
また、第２シールド手段も、遊技制御装置４０や排出制御装置５０の裏機構盤本体２２側の面に設置するほか、電源線や信号線などの配線の背面側に制御装置などの電気機器を配設する場合に、その間に設置することで同様の効果が得られる。
【００８７】
また、その他の実施の形態として遊技制御装置４０の縦断面図である図１７に示すように、第２シールド手段の設置箇所についても次のような幾つかの変形例がある。すなわち、図１７（ａ）に示すように、遊技制御装置４０の基板ボックス４０Ａの底面部（遊技機正面側の面部）を金属板６０Ａで形成し、その金属板Ａを非導電性の合成樹脂で覆って第２シールド手段としたり、或いは、図１７（ｂ）に示すように、金属性の第２シールド手段６０Ｂを基板ボックス４０Ａの内部、遊技制御基板４５と基板ボックス４０Ａの底面との間に収容するように構成しても良い。このように構成することで、基板ボックス４０Ａと第２シールド手段とを一体的に取り扱えるので、組み立て時やメンテナンス時における作業性が向上する。
【００８８】
その他、裏機構盤に配設される装置や機構の種類、裏機構盤が組み付けられる遊技機のフレーム構成、遊技機の前面側に配設される装置や機構の種類など、この実施の形態で示した具体的な構成は様々な変更が可能である。
【００８９】
【発明の効果】
以上、本発明によれば、球流路と制御基板等の電気機器との間に配線を整然と収容できるとともに、球流路を流下する遊技球から発生される電磁ノイズが配線に乗って電気回路の動作を狂わすといった不具合を第１シールド手段により防止でき、更に配線から生じる電磁ノイズが制御基板等の電気機器に影響してその動作を狂わすといった不具合を第２シールド手段により防止できるという効果が得られる。
また、制御装置取付ベースが、制御装置の取付ベースと、配線案内部と、第２シールド手段の固定部とを兼ねた構成となるので、部品点数の削減と組付工程の削減を図ることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a game board having a plurality of electric game devices arranged on the front surface for providing a game by a game ball, a ball discharge device for discharging a game ball to be paid out to a player, and an electric power related to the game. The present invention relates to a gaming machine having a back mechanism board provided with a control device for controlling a game machine, wherein the back mechanism board is installed on the back side of the game board.
[0002]
[Prior art]
Conventionally, a game board in which various amusement gates and electrical game devices called bonuses are arranged in the game area is detachably attached to the game machine main body, and a ball is discharged or played on the back side of the game machine main body. There is known a gaming machine such as a pachinko gaming machine in which a back mechanism board in which various devices necessary for gaming such as control are arranged.
[0003]
The back mechanism board is a tank that stores game balls to be supplied to the player in the back mechanism board body, which is the base frame, and a predetermined number of prize balls for the winning when the game balls are won at the winning opening. Game control device (game control) that controls various games such as a ball discharge device that discharges the game balls, a chute that aligns the game balls from the tank that stores the game balls before discharging the prize balls and leads them to the ball discharge device, and an electrical game device control Substrate), a discharge control device (discharge control substrate) for controlling discharge of the ball discharge device, and a power supply unit for distributing power to each device.
[0004]
In addition, the back mechanism board main body, which is the base frame of the back mechanism board, has an opening in the center that allows the back of the game board to face, and a ball (winning prize) that flows from the game board below the opening. A collection basket that collects balls and outballs and guides them to the island facility side, and a discharge bowl that guides prize balls and rental balls discharged from the ball discharge device to the discharge tray on the front side of the gaming machine. .
[0005]
That is, the conventional back mechanism panel includes a spherical flow path including a tank and a chute, a spherical flow path in a spherical discharge device, and a spherical flow path such as a collection basket and a discharge basket. There were a number of spherical channels.
[0006]
On the other hand, the back mechanism board has a motor that moves the game ball in the ball discharge device, a half-end sensor that detects a decrease in the game ball stored in the tank, and an overflow that detects the overflow of the game ball with the discharge basket. Many electrical components such as a state detection sensor and a discharge ball detection sensor for detecting a discharge ball with a ball discharge device are provided, and these are connected to the above-described control board via wiring. Further, the power supply unit and each control board are connected via power supply wiring, and power is supplied to each control board via the power supply wiring.
[0007]
As described above, many control devices are attached to the back mechanism panel, and wiring such as signal lines and power supply lines is connected to electrical components of each device.
[0008]
In such a situation, conventionally, the game control board and the discharge control board have been generally installed on the back side of the collection basket and the discharge basket having a relatively large space. Also, if the wiring connected to each electrical component is exposed on the back of the back mechanism panel, the operator will be hooked and connector disconnection or disconnection is likely to occur. It is better to arrange the inside of the board. Therefore, conventionally, in a pachinko gaming machine, wiring is generally provided between a control board such as a game control board or a discharge control board and a ball passage such as a collection basket or a discharge basket.
[0009]
[Problems to be solved by the invention]
By the way, it is known that a gaming machine receives noise from an external device such as an island facility and also generates noise from the gaming machine itself. For example, when a game ball flows down the ball flow path, static electricity is accumulated and electromagnetic noise is generated by the static electricity, or when a plurality of game balls come in contact from a discrete state, electrons move between the game balls. In particular, large electromagnetic noise may be generated.
[0010]
If such noise gets on the circuit in the control board, there is a risk that the program will run out of control, so conventionally, a software workaround has been taken to prevent it, and the GND area of the control board has been reduced. Various countermeasures against noise were taken, especially on game control boards that supervise games, such as taking large.
[0011]
However, in places where wiring is provided near the spherical flow path where noise occurs, such as between the control board and the spherical flow path, noise affects the control board circuit by riding on the wiring, causing malfunctions. There was a risk that it could cause problems or unstable operation.
[0012]
In order to avoid such inconvenience, it is conceivable not to arrange the wiring on the back side of the spherical flow path so that noise does not get on the wiring, but as described above, the back mechanism board However, since various devices are arranged narrowly, it is difficult to bypass and arrange the wiring so as to avoid the back side of the spherical flow path, and the back of the back mechanism board through the back side of the control board It is conceivable to arrange the wiring so that it floats on the board, but the electronic components on the control board become invisible, which may cause problems in fraud prevention, and as mentioned above, if the wiring is floating, the gaming machine There is a possibility that problems such as disconnection of the connector and disconnection of the wiring may occur by hooking the wiring somewhere during the transportation or maintenance.
[0013]
Also, for example, power lines that supply AC power generate magnetic field changes around the wiring itself, and the wiring itself is also a source of noise, so the control board in which the noise generated in the wiring is arranged in the vicinity of the wiring There was also a fear of getting on the circuit.
[0014]
The present invention has been made in view of the above circumstances, and provides a gaming machine capable of preventing noise from getting on the wiring arranged on the back mechanism board of the gaming machine and arranging the wiring in an orderly manner. The purpose is to do.

And a plate-shaped first shield means for blocking electromagnetic waves generated by the game balls flowing down the ball flow path from being transmitted to the wiring, between the ball flow path and the control device mounting base. In addition, a plate-like second shield means for blocking electromagnetic waves from the wiring is provided between the control device mounting base and the control device, and a plurality of fitting bosses are provided on the back side of the back mechanism board. The first shield means is formed with a first locking hole into which the fitting boss can be fitted at a position corresponding to the fitting boss. Hangs upward at the tip A plurality of locking claws having a return portion and a clamping boss are formed, and the second shield means is formed with a second locking hole that is hooked by the locking claw at a position corresponding to the locking claw.
