Description

【０００１】
【発明の属する技術分野】
本発明は、パチンコ機等に開閉自在に装着される扉枠が無用に開放されるのを知らせる検知スイッチを備えたパチンコ球を使用する遊技機に関するものである。
【０００２】
【従来の技術】
従来のパチンコ球を使用する遊技機には、遊技客が扉枠を無断で開放し、不正に賞球を獲得する行為を防止するため、扉枠の開放を検知して報知する防犯用の検知スイッチが前面枠に設けられていた。また、前記検知スイッチの多くが扉枠の開放側に位置して設けられていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、従来のパチンコ球を使用する遊技機にあっては、検知スイッチの配線基板は機構板に設けられており、前面枠および機枠に設けられていた検知スイッチの配線を機構板側に設けた配線基板に接続しなければならず、配線作業に非常に手間が掛かるという問題があった。
【０００４】
本発明は、上記した問題点に鑑みてなされたもので、その目的とするところは、防犯用の検知スイッチの取付や配線作業が容易にできるようなパチンコ球を使用する遊技機を提供することにある。
【０００５】
【課題を解決するための手段】
上記の目的を達成するための手段として、請求項１の発明は、機枠と、該機枠の前面側に設けられ、軸部を介して前記機枠に対して開閉可能な前面枠と、該前面枠の前面側に設けられ、軸部を介して前記前面枠に対して開閉可能な扉枠と、前記前面枠の裏面側に設けられ、軸部を介して前記前面枠に対して開閉可能な機構板と、遊技領域を備える遊技体とを備え、前記扉枠に設けられる視認部を介して前記遊技領域を視認可能としたパチンコ球を使用する遊技機において、前記前面枠に対して開閉可能な機構板に、検出スイッチと、該検出スイッチと電気的に接続される配線が接続される基板とを設け、前記前面枠に、貫通収納部と、該貫通収納部に配設される触子と、該触子と共に前記貫通収納部に収納される付勢部材によって前記触子を常に前記扉枠側に付勢する付勢手段とを設け、前記扉枠に、前記触子と当接する当接部を設け、前記触子は、前記扉枠が前記前面枠に対して閉止状態にあるときは、前記当接部に押圧されて第 1 の位置で維持され、前記扉枠が前記前面枠に対して開放状態にあるときは、前記付勢手段によって前記扉枠側に付勢されて第２の位置で維持されるものであり、前記検出スイッチは、前記触子の位置の変化に基づいて検出状態が変化し、該検出状態の変化に基づいて前記前面枠に対する前記扉枠の開閉状態を検出可能とし、さらに前記触子は、前記扉枠の開放時に前記第１の位置から第２の位置に変位するまで前記扉枠の当接部を押圧することを特徴とする。
【０００６】
請求項２の発明は、請求項１に記載のものにおいて、前記触子は、棒状に形成されるとともに前記付勢部材と係合する係合部を備え、前記付勢手段は、前記触子に添って前記貫通収納部に収納される前記付勢部材と、該付勢部材が前記触子を付勢した状態で前記貫通収納部に収納されるように支持する支持部材とを備えることを特徴とする。
また、請求項３の発明は、請求項１または２に記載のものにおいて、前記機枠は、ヒンジ具を有する取り付け用の枠であることを特徴とする。
また、請求項４の発明は、請求項１から３のいずれかに記載のものにおいて、前記機構板は、少なくとも遊技球を貯留する球タンク、遊技球を払出す球払出装置、または遊技板面に取り付けた電気的装置の後部が臨む窓部のいずれかを有することを特徴とする。
【０００７】
【発明の実施の形態】
次に、本発明の一実施の形態を図面を参照して説明する。図１はパチンコ遊技機の正面図、図２はパチンコ遊技機の裏面図、図３は機構板を開放した状態のパチンコ遊技機の裏面斜視図である。図において、１はパチンコ遊技機の機枠であり、該機枠１の前面に額縁状に形成された前面枠２が開閉自在に取付けられている。該前面枠２の裏面側に該前面枠２と一体に設けられた合成樹脂製の遊技盤取付枠３を介して遊技盤４が取付けられており、その前面を覆うようにガラス扉枠５および前面板６が着脱かつ開閉自在に装着され、該前面板６の前面に打球を供給する上部球受皿７が装着されている。また、前面枠２の下部には上部球受皿７の余剰球を貯留する下部球受皿８と、打球の発射強さを加減する操作ハンドル９が設けられる。なお、本実施の形態では前面枠２と遊技盤取付枠３とを合成樹脂により一体に形成したものとして例示しているが、前面枠２と遊技盤取付枠３とをそれぞれ別体に成形したものであってもよい。
【０００８】
前面枠２の左側縁部はヒンジ具８８を介して機枠１の左端部に蝶着され、ガラス扉枠５の左側縁部も前面枠２の左端部に蝶着されている。そして、自由端を施錠装置８９によって機枠１および前面枠２に閉止状態で施錠しており、前面枠２の前面に設けられたシリンダー錠Ｓの操作によって前記施錠装置８９を作用して前面枠２およびガラス扉枠５を開閉するようになっている。
【０００９】
前記遊技盤取付枠３は、図３および図４に示すように遊技盤４の下端を支持する下枠部３ａとコ字形の上枠部３ｂとからなり、下枠部３ａの前面側に発射レール１８が取着され、該発射レール１８と前記ガイドレール１０との間に開設されるファール球口１９から落下するファール球および前面板６の開放時に、上部誘導路２０から落下する零れ球を受けて下部球受皿８に導くファール球樋２１が形成される。該ファール球樋２１は前面枠２に形成された球導出樋２２を介して下部球受皿８と連通しており、ファール球樋２１に受けられたパチンコ球は、前面枠２の後方に迂回することなく下部球受皿８に導かれる。２３は上部球受皿７に貯留されたパチンコ球が球抜きされる球抜き樋である。
【００１０】
前記ガラス扉枠５は、前面枠２の上半部分を全幅にわたって覆う大きさに形成され、その中央部に遊技盤４の遊技領域４ａが視認可能な方形状の開口が形成される合成樹脂製の本体枠５ａと、該本体枠５ａの裏面側に装着される金属製の補強板５ｂとから構成されている。
【００１１】
前記遊技盤４の前面に遊技球を案内するガイドレール１０が設けられ、このガイドレール１０によって囲まれる遊技領域４ａに一般入賞口１１や可変表示装置１２の図柄を変動させる始動入賞口１３、また可変表示装置１２の予め設定された図柄の組合せにより開放する大入賞口１４等が設けられ、遊技部４ａの最下端にアウト口１５が設けられている。なお、大入賞口１４は、取付板１６に形成した横長の開口に開閉扉１７を前後方向に開閉自在に設け、電気的駆動源により開閉扉１７を開閉する周知のものである。
【００１２】
また、遊技盤４の裏面には入賞球集合カバー２５および機構板２６が配設されており、入賞球集合カバー２５の裏面に遊技内容を制御する回路基板が収納される基板ボックス２７が装着されている。一方前記機構板２６は、ヒンジ具２８によって開閉自在に装着され、図２および図３に示すように機構板の開放側および上下に位置して遊技盤取付枠３に設けられた機構板固定手段としての複数の係止具２９と、機構板４に設けられた係止孔３０とにより、機構板２６を遊技盤４の裏面に密着させた状態に圧接して固定するようにしている。
【００１３】
前記係止具２９は、軸部３１と該軸部３１から両側に突出する摘みを兼ねる係止部３２，３２を備え、該係止部３２下面には押圧突起３３を設けており、遊技盤取付枠３の軸３４に木ネジ３５によりに回動自在に螺締めされている。そして、図５鎖線に示すように係止部３２が係止孔３０に嵌る位置と同図実線に示す係止部３２が係止孔３０に嵌合した状態とに規制突起３６，３７により回動規制されている。また、係止部３２が係止孔３０に嵌る位置に規制する規制突起３６は、前記係止孔３０に臨んで機構板２６の位置決めとなると共に荷重を支持するようにしている。
【００１４】
また、前記機構板２６は、合成樹脂により方形状に形成されており、ほぼ中央に前記可変表示装置１２の後部が臨む窓部４２が開設されており、該窓部４２の上方にパチンコ球を貯留する球タンク４３が取付けられる。また、球タンク４３の下方にはパチンコ球を整列して導き出す球誘導樋４４が設けられ、その下流端は、屈曲誘導樋４５を介して所定数のパチンコ球を払出す球払出装置４６が接続されている。
【００１５】
前記球払出装置４６の下方には、該球払出装置４６から払出されたパチンコ球を球導出路４７，上部誘導路２０を介して上部球受皿７に導く球排出樋４８および球抜き樋４９が並設されている。そして、前記開口窓４２より下方の機構板２６部分は、パチンコ球の直径よりも僅かに大きい程度の前後幅寸法とした薄幅に形成され、かつ前面部が開口された凹室状の同一内側空間部として構成されている。そして、その同一内側空間部に前面が開口された樋状の入賞球集合通路５０と入賞球と共にアウト球を合流して機外に排出する排出通路５１と、余剰球通路５２と、球抜き通路５３が集約して形成されており、前記球排出樋４８および球抜き樋４９が開口５４，５５を介して余剰球通路５２と球抜き通路５３の上流部分に連通されるようになっている。
【００１６】
前記余剰球通路５２の下流側には球量検出機構５６が設けられている。この球量検出機構５６は、下端が軸５７により揺動自在に軸支された板状の検知部材５８とマイクロスイッチ５９とを有し、余剰球通路５２に賞球が充満するとその余剰球によって検知部材５８が押されて揺動し、マイクロスイッチ５９を作動するもので、該マイクロスイッチ５９の作動によりその信号が制御回路に送られてパチンコ球の払出動作を停止したり打球の発射動作を不能にする等して遊技を不能動化するようになっている。また、余剰球通路５２の終端に下部球受皿８の球出口６０後面に設けられた下部誘導路６１が位置している。
【００１７】
また、図３および図５に示すように遊技盤４および遊技盤取付枠３の下枠部３ａの一部を前記入賞球集合通路５０と入賞球と共にアウト球を排出する排出通路５１と、余剰球通路５２と、球抜き通路５３の通路壁６２としており、機構板２６を前記固定手段としての複数の係止具２９により遊技盤４に密着固定することにより、前記入賞球集合通路５０および排出通路５１，余剰球通路５２，球抜き通路５３にパチンコ球が流下可能な状態となるように構成している。特に上記通路部５０〜５３の近傍に機構板２６の固定手段２９，３０を設けることで、より密着が確実なものとなる。
【００１８】
また、該余剰球通路５２と球抜き通路５３の通路壁６２部分を導電性を有する金属製のカバー板６２ａとしてビス着等の適宜手段により取付けており、さらに該金属製のカバー板６２ａの上縁を屈曲して不正防止用リブ６３を形成して、球出口６０から侵入するピアノ線等の不正具の侵入を防ぐようにしている。なお、金属板６２ａに替えて導電性素材を混合した合成樹脂により成形してもよい。また、前記不正防止リブ６３を余剰球通路５２および球抜き通路５３に沿うように設けることで不正防止と共に通路部の撓み防止の効果も生ずる。さらに、遊技盤取付枠３および遊技盤４の裏面を通路部の側壁とするだけでなく、機構板２６を側壁として遊技盤取付枠３および遊技盤４に通路部の一部を設けるようにして、機構板２６を遊技盤４裏面に装着することによって通路部としての機能をなすようにしてもよい。このとき、通路壁６２を下枠部３ａと別体に形成することで成形しやすくなる。
【００１９】
しかして、機構板２６の開放側および軸支側に、ガラス扉枠５および前面枠２の開放を検知する検知スイッチ３８，３９が設けられている。前記ガラス扉枠５用の検知スイッチ３８は、図８および図１３に示す前面枠２に設けた触子４０を介して検知するようにしている。該触子４０は、ほぼ前面枠２および遊技盤取付枠３の厚さ分の長さを有した棒状に形成され、途中に抜け止め鍔部４０ａを設けている。そして、図１２および図１３に示すように遊技盤取付枠３の上枠部３ｂに貫通して設けられた収納部６４に付勢部材のスプリング６５と共に収納され、支持蓋６６をビス着６７することで、付勢部材のスプリング６５によって常に先端が前面枠２の前面に突出し、後端が支持蓋６６から臨むように設けられる。なお、付勢部材により付勢された触子４０により、シリンダー錠Ｓの操作によって前記施錠装置８９を解錠操作することによりガラス扉枠５を自動的に開かせることができる。
【００２０】
前記検知スイッチ３８は、本実施の形態において常閉接点を有するマイクロスイッチであり、取付部材６９を介して機構板２６に取付けられる。該取付部材６９は、図１０に示すように検知スイッチ３８の装着板部６９ａと機構板２６への取付板部６９ｂとで断面Ｔ型をしており、検知スイッチ３８を装着板部６９ａの位置決めピン７０で位置決めしてビス７１により組付ける。そして、検知スイッチ３８を組付けた取付部材６９は、図１１および図１２に示すように機構板２６の開放側上部隅角に前後に貫通して設けられた取付凹部７２に後方から嵌め込み、弾性係止片７３とビス７４により、前記触子４０の後端と検知スイッチ３８の検知部３８ａと対向位置するように取付けられる。そして、検知スイッチ３８の配線Ｈは、図８に示すように機構板２６前面側に設けた配線収納溝７５を介して中継基板４１に接続される。
【００２１】
上記構成の検知スイッチ３８は、図１２に示すようにガラス扉枠５が前面枠２に対して閉じられると、スプリング６４の付勢によって前面枠２の前面に突出した触子４０がガラス扉枠５の補強板５ｂ裏面に当たることで触子４０の後端で検知部３８ａを押圧して検知スイッチ３８をオフ状態とし、ガラス扉枠５が閉じていることが検出される。一方、図１２鎖線に示すようにガラス扉枠５が開けられると逆に触子４０がスプリング６４の付勢によって前面枠２の前面に突出し、検知部３８ａの押圧を解除し検知スイッチ３８はオン状態となり、ガラス扉枠５が開放されたことを直ちに知らせるようにしている。
【００２２】
なお、取付凹部７２の前面開口部を例えば図１４に示すように前記触子部の支持蓋６６と同形状として機構板２６を閉じる際の位置決めとしてもよい。このとき支持蓋６６の上面をテーパー面とすることで、図１４鎖線に示すように球タンク４３のパチンコ球等の重量により自由端側が下降しても、テーパー面により正規な位置にガイドするガイド機能を備えることができる。また、本実施の形態は棒状の触子４０を介して検知スイッチ３８を作用するようにしたが、本体枠５ａまたは透光性のランプ用レンズ，基板保護カバー，音源手段の保護カバー等のガラス扉枠５に設けられた部材を後方に突出して触子５ｃを形成して検知部３８ａを押圧するようにしてもよく、例えば図１５に示すように、ガラス扉枠５の補強板５ｂを後方に突出して触子５ｃを形成して直接検知部３８ａを押圧するようにすればよい。このように、一体的に触子５ｃを延出しても受ける場合、触子５ｃが長くなるため、強度的に強いのが望ましく、リブで補強したり補強板５ｂ等の金属製の部材とすることが望ましい。また同様に、機構板２６の前面側に検知スイッチ３８の取付部を膨出してガラス扉枠５で直接検知スイッチ３８を作用させると共に、該膨出部を機構板２６を閉じる際の位置決めとしてもよい。
【００２３】
次に、前面枠２用の検知スイッチ３９について説明する。検知スイッチ３９は、常閉接点を有するマイクロスイッチであり、取付部材７６を介して機構板２６に取付けられる。該取付部材７６は、図１７に示すようにＬ型の板状部７６ａに位置決めピン７７が突設され、検知スイッチ３９を該位置決めピン７７で位置決めしてビス９０により組付ける。そして、図１６および図１８に示すように機構板２６の軸支側側縁に設けた取付部７８のボス７８ａ，７８ａにビス着７９することで取付けられ、検知スイッチ３８の配線Ｈは中継基板４１に接続される。なお、検知スイッチ３９は、前面枠２を閉じた状態で作動片３９ａが直接機枠１に接触する位置関係が設定される。
【００２４】
このように取付けられた検知スイッチ３９は、図１９に示すように前面枠２が機枠２に対して閉められ、前面枠２が機枠１と係止する位置に至ると、作動片３９ａが機枠１に直接当たることにより、検知スイッチ３９はオフし前面枠２が閉じていることが検出される。一方、図１９鎖線に示すように、前面枠２が開けられると検知スイッチ３９の作動片３９ａが機枠１から離れることになり、該検知スイッチ３９はオンし前面枠２が開いていることが検出される。なお、機枠１の検知スイッチ３９との接触部に摩耗防止等のために別部材を設けるようにしてもよい。
【００２５】
上記したように、ガラス扉枠５および前面枠２の開閉を検知する検知スイッチ３８，３９を機構板２６に設けることで中継基板４１への配線の簡略化を図ることができ、取付部材６９，７６を介して取付けることで検知スイッチ３８，３９を保護すると共に故障による検知スイッチ３８，３９の交換も簡単に行うことができる。また、当然のことながら、機構板２６に設ける検知スイッチ３８，３９は機構板２６本体に限られることなく、機構板２６に設けられる球タンク４３，球誘導樋４４，屈曲誘導樋４５，球払出装置４６等に設けてもよく、これらの部品を機構板２６に取付ける際に共締めするか、あらかじめこれらの部品と検知スイッチ３８，３９とをユニット化しておけば、組付け作業を容易にすることができる。また、これらの部品の近傍に設けられた配線基板に配線を接続すれば配線の取付作業性も向上する。
【００２６】
また、図２０ないし図２２は検知スイッチ３８，３９の取付の他の実施の形態を示し、検知スイッチ３８，３９は取付部材としてのケース体８０を介して取付けるようにしている。ケース体８０は、図２０に示すように側面が開放した検知スイッチ３８，３９が収納可能な箱状本体８０ａと開口を閉塞する蓋体８０ｂとからなり、箱状本体８０ａに検知スイッチ３８，３９の位置決め突起８４が設けられ、側壁には透孔８７が形成されると共に、該透孔８７から臨んで検知部材８３が設けられる。該検知部材８３の側面はスムーズに作用するようにテーパー面８３ａとしている。８５はケース体８０の一端に形成された軸筒部であり、ケース体８０が揺動自在に取付けるようにしている。８６は軸筒部８５の対角位置に設けられた弾性手段としての弾性片であり、確実に検知スイッチ３８，３９が作用するようにしている。
【００２７】
上記構成のケース体８０は、箱状本体８０ａに検知スイッチ３８，３９を位置決め突起８４により位置決めして収納し、該蓋体８０ｂに設けた係止孔８１を箱状本体８０ａの係止爪８２に係止することによりビスを使用することなく組立てられる。このとき検知部３８ａ，３９ａと検知部材８３は対向位置にある。
【００２８】
上記ケース体８０を使用した実施の形態を前面枠２用の検知スイッチ３９において説明する。検知スイッチ３９を備えたケース体８０は、軸筒部８５を取付部７８のボス７８ａに嵌挿しビス着７９することで揺動自在に取付け、前記弾性片８６を機構板２６の側壁に当接させる。そして、このように取付けられた検知スイッチ３９は、図２２に示すように検知部材８３が機枠１に直接当たることで検知スイッチ３９はオフし、同図鎖線に示すように前面枠２が開けられることで機枠１から外れ該検知スイッチ３９はオンする。このとき、機枠１の側板が内方に撓んだり変形したりして検知スイッチ３９との位置関係がずれていても、弾性片８６の弾性によりケース体８０が軸筒部８５を軸として内方に揺動して確実に検知スイッチ３９が作用することができる。
【００２９】
このように、検知スイッチ３８，３９がケース体８０に保護されているので破損し難く、衝撃による支障も起こり難い。また、ケース体８０に弾性片８６を設けることで衝撃を吸収すると共に位置関係がずれても弾性片８６の弾性によりずれ分を吸収することができる。なお、弾性片８６はケース体８０に設けることなく、機構板２６側に設けるようにしても同様の効果を得ることができる。また、弾性手段として弾性片を使用して説明したが、スプリング，板ばね等にしてもよく弾性機能により衝撃等を吸収するようにすればよく、例えば検知スイッチ３８，３９自体を揺動自在に装着し、機構板２６側に設けた弾性部材により衝撃等を吸収したり、枠体に検知スイッチ３９全体をスプリングによって可動自在に設けたりするようにすればよい。上記実施の形態の内容は当然のことながらガラス扉枠５用の検知スイッチ３８にも適用可能である。
【００３０】
上記したように、ガラス扉枠５および前面枠２の開閉を検知する検知スイッチ３８，３９をそれぞれ別々に設けるようにしたが、一つの検知スイッチでガラス扉枠５および前面枠２の開閉を検知することも可能である。例えば機構板２６を機枠１に固定して、検知スイッチ３８を使用することによりガラス扉枠５の開閉は上記実施の形態のように検知し、前面枠２の開閉は前面枠２を開放することにより図１４に示すように機構板２６と前面枠２が離れた状態となり、触子４０が検知部３８ａの押圧を解除し検知スイッチ３８はオン状態となり、前面枠２が開放されたことを検知することができる。また、検知スイッチ３８を揺動自在に設け、前面枠２およびガラス扉枠５を閉じた状態で機枠１と触子とで検知スイッチ３８を挟んでオフ状態とし、ガラス扉枠５を開放すると触子４０が検知部３８ａの押圧を解除し検知スイッチ３８はオン状態となってガラス扉枠５の開放を検知し、前面枠２を開放すると機枠１との接触が解除されて検知スイッチ３８が自重で揺動することにより触子４０の押圧を解除し検知スイッチ３８はオン状態となり前面枠２の開放を検知することができる。
【００３１】
なお、本実施の形態において検知スイッチ３８，３９を常閉接点を有するマイクロスイッチとしたが、発光部と受光部とからなる光学式センサとしてもよく、ガラス扉枠５および前面枠２の閉鎖時に発光部と受光部間に検知片等が臨むことによってガラス扉枠５および前面枠２が閉じていることを検知するようにしてもよい。
【００３２】
また、ガラス扉枠５の開閉検知スイッチ３８を機構板２６に設けることで、ガラス扉枠５の開閉を検知できるのはもちろんのこと、逆に機構板２６が確実に固定されているかどうかを確認することも可能である。本実施の形態の開閉式の機構板２６であれば、運搬時におけるセットずれの確認やホールにおける球詰りの解除や出荷前の点検後の閉鎖確認としても有効である。
なお、機構板２６は開閉式のものに限られることなく、引掛け式や固着式のものであっても機構板２６のセット確認を識別するものとして使用することができる。
【００３３】
【発明の効果】
以上に述べたように本発明に係わるパチンコ球を使用する遊技機は扉枠の開閉を検知する検出スイッチを機構板に設けるようにしたので、機構板以外に配線する必要がなく配線作業を極めて容易にすることができる。
