Description

【０００１】
【発明の属する技術分野】
本発明は、外枠に対し開閉可能に取り付けられた前枠と、該前枠が開かぬように施錠するとともに手動操作により開錠される前枠施錠機構とを有する遊技機に設けられ、前記前枠施錠機構の開錠動作を阻止し得る施錠ロック装置に関する。
【０００２】
【従来の技術】
従来、パチンコ機等の遊技機は、箱状の外枠の正面側に前枠が開閉可能に取り付けられており、前枠を開いた際に遊技盤面上の各種役物や釘等の調整ができるようになっている。そして遊技機には、前記前枠が開かぬように施錠するとともに手動操作により開錠される前枠施錠機構が設けられていた。
【０００３】
一般に前枠施錠機構は、前枠を閉じた際に、前枠側に設けた鈎部材が外枠側に設けた鈎受けに対して係合するようになっており、前枠側に設けられた鍵穴に鍵を差し込んで回した場合に、鈎部材が鈎受けから外れて開錠され、前枠を開くことができるように構成されていた。
【０００４】
【発明が解決しようとする課題】
しかしながら、前述した従来の遊技機の前枠施錠機構では、鍵を使った手動操作だけで前枠を容易に開けることができたため、悪意を持った者が合い鍵等で前枠を開けることは比較的容易であり、遊技機の裏面側に配された制御基盤等を故意に改変するような不正行為を防止することが難しかった。
【０００５】
こうした不正行為を防止するために、最近では前記前枠施錠機構よりも厳重な施錠が可能であり、手動操作に基づく機械的動作だけでは開錠できない電動式の施錠装置の開発も進んでいる。かかる電動式施錠装置は、例えば閉店後に給電が断たれると前枠を閉状態に拘束し、営業時間内にて給電するとその間だけ前枠の開閉を許容するような開閉制御機構を備えるように構成される。
【０００６】
ところが、既存の施錠機構を一々取り外して新たに電動式施錠装置を取り付けるとなると、大掛かりな改修工事が必要となり、多大なコストがかかるという問題があった。しかも、前記電動式施錠装置では、前枠の開閉を許容する間はずっと給電し続ける必要があるため、給電に基づく発熱対策が別途必要となり、更には余分に消費電力がかかって経費削減も困難になるという問題も生じる。
【０００７】
本発明は、以上のような従来技術が有する問題点に着目してなされたもので、既存の前枠施錠機構を備えた遊技機に付加するだけで、該前枠施錠機構に対する不正な開錠操作を確実に防止でき、しかも確実な操作や制御が可能となる電動式であるにもかかわらず、消費電力や発熱を抑えることが可能な施錠ロック装置を提供することを目的としている。
【０００８】
【課題を解決するための手段】
前述した目的を達成するための本発明の要旨とするところは、次の各項に存する。
［１］外枠（２）に対し開閉可能に取り付けられた前枠（３）と、該前枠（３）が開かぬように施錠するとともに手動操作により開錠される前枠施錠機構（１０）とを有する遊技機（１）に設けられ、前記前枠施錠機構（１０）の開錠動作を阻止し得る施錠ロック装置（２０）であって、
前記前枠施錠機構（１０）の開錠動作を阻止するロック部材（３０）と、該ロック部材（３０）を拘束及び拘束解除可能なストッパ部材（４０）と、前記ロック部材（３０）及びストッパ部材（４０）を選択的に駆動する駆動手段（５０）とを有し、
前記ロック部材（３０）は、前記前枠施錠機構（１０）の開錠動作を直接阻止するロック位置と、前記前枠施錠機構（１０）の開錠動作を許容するロック解除位置とに変位可能に設けられ、
前記ロック部材（３０）をロック位置側に付勢する第１付勢手段（２８）と、前記ストッパ部材（４０）を拘束位置側に付勢する第２付勢手段（２９）とを有し、
前記駆動手段（５０）は、給電されると作動するソレノイド（５１）と、該ソレノイド（５１）の動力を前記ロック部材（３０）及びストッパ部材（４０）に選択的に伝達する動力伝達機構（５５）とから成り、
前記ソレノイド（５１）は、一時給電される毎に一往復運動するプランジャ（５２）を備え、
前記動力伝達機構は、前記プランジャ（５２）が一往復運動する度に、前記ロック部材（３０）に動力が伝達され、前記第１付勢手段（２８）の付勢力に抗して前記ロック部材（３０）がロック解除位置に変位して、前記ストッパ部材（４０）が前記第２付勢手段（２９）の付勢力により拘束位置に変位する状態と、前記ストッパ部材（４０）に動力が伝達されると、前記第２付勢手段（２９）の付勢力に抗して該ストッパ部材（４０）が拘束解除位置に変位して、前記ロック部材（３０）が前記第１付勢手段（２８）の付勢力によりロック位置に変位する状態とに交互に切り替えることを特徴とする施錠ロック装置（２０）。
【０００９】
［２］前記ストッパ部材（４０）に係合部（４２）を設け、
前記ロック部材（３０）に、該ロック部材（３０）がロック解除位置にあるとき前記係合部（４２）が係合し、かつ前記ストッパ部材（４０）が拘束解除位置にあるとき前記係合部（４２）が離脱する被係合部（３６）を設け、
前記係合部（４２）が被係合部（３６）に係合することで、前記第１付勢手段（２８）の付勢力に抗して、前記ロック部材（３０）がロック解除位置に保持されるように設定したことを特徴とする［１］記載の施錠ロック装置（２０）。
【００１０】
［３］前記ロック部材（３０）がロック位置またはロック解除位置にあるかを検出する位置検知手段（５８）を有することを特徴とする［１］または［２］記載の施錠ロック装置（２０）。
【００１３】
次に前述した解決手段に基づく作用を説明する。
［１］記載の施錠ロック装置（２０）によれば、前枠施錠機構（１０）の開錠動作を阻止するセキュリティ状態にて、駆動手段（５０）に一時給電すると、該駆動手段（５０）の作動によりロック部材（３０）がロック解除位置に変位させられ、この変位に伴いストッパ部材（４０）は拘束位置に変位する。
【００１４】
するとロック部材（３０）は、前記前枠施錠機構（１０）の開錠動作を許容するロック解除位置にストッパ部材（４０）で保持され、給電が断たれた後も、前枠施錠機構（１０）の開錠動作を直接阻止するロック位置に戻ることはない。このとき、前枠施錠機構（１０）の手動による開錠動作が妨げられることはなく、前枠（３）は開閉自在となる。
【００１５】
このようなセキュリティ解除状態にて、再び駆動手段（５０）に一時給電すると、該駆動手段（５０）の作動により、今度はストッパ部材（４０）が拘束解除位置に変位させられ、この変位に伴いロック部材（３０）がロック位置に変位する。ロック部材（３０）は、給電が断たれた後もそのままロック位置に保持されて、元のセキュリティ状態となる。
【００１６】
以上のように、本施錠ロック装置（２０）によれば、駆動手段（５０）によって、ロック部材（３０）を直接的にロック解除位置または間接的にロック位置へと変位させることができ、ロック部材（３０）がロック位置にあるときは、前枠施錠機構（１０）の開錠動作が規制されるため、手動でこの開錠動作を行おうとしても操作不能であり、前枠（３）を開けることができず、不正行為を確実に防止することができる。
【００１７】
しかも、駆動手段（５０）に給電するのは、前記セキュリティ状態またはセキュリティ解除状態の何れか一方から他方に切り換える際の一時だけで済むから、長時間に亘る給電による発熱に対する特別な対策は不要であり、また消費電力も極力抑えることが可能となる。
【００１８】
また、［１］記載の施錠ロック装置（２０）では、前記駆動手段（５０）の動力で前記ロック部材（３０）を、第１付勢手段（２８）の付勢力に抗してロック解除位置に変位させると、前記ストッパ部材（４０）は、駆動手段（５０）の動力とは直接関係なく、ロック部材（３０）の変位に伴い第２付勢手段（２９）の付勢力によって拘束位置に確実に変位する。
【００１９】
一方、前記駆動手段（５０）の動力で今度は前記ストッパ部材（４０）を、第２付勢手段（２９）の付勢力に抗して拘束解除位置に変位させると、前記ロック部材（３０）は、駆動手段（５０）の動力とは直接関係なく、ストッパ部材（４０）の変位に伴い第１付勢手段（２８）の付勢力によってロック位置に確実に変位する。また、前記駆動手段（５０）は、ソレノイド（５１）と、該ソレノイド（５１）の動力を前記ロック部材（３０）及びストッパ部材（４０）に選択的に伝達する動力伝達機構（５５）とから構成すればよい。
【００２０】
［２］記載の施錠ロック装置（２０）では、ロック部材（３０）がロック解除位置にあるとき、ストッパ部材（４０）が拘束位置に変位してその係合部（４２）がロック部材（３０）の被係合部（３６）に係合すると、この係合関係により、前記第１付勢手段（２８）の付勢力に抗して、前記ロック部材（３０）がロック解除位置に保持される。
【００２１】
一方、前記ストッパ部材（４０）が拘束解除位置に変位すると、それに伴いストッパ部材（４０）の係合部（４２）がロック部材（３０）の被係合部（３６）から外れてロック部材（３０）の拘束が解除され、それによりロック部材（３０）は、前記第１付勢手段（２８）の付勢力によってロック位置に復帰する。
【００２２】
また、［３］記載のように、前記ロック部材（３０）がロック位置またはロック解除位置にあるかを検出する位置検知手段（５８）を備えれば、本施錠ロック装置（２０）が、セキュリティ状態にあるのかセキュリティ解除状態にあるのかを正確に把握することができる。
【００２３】
【発明の実施の形態】
以下、図面に基づき本発明を代表する実施の形態を説明する。
図１〜図８は本発明の一実施の形態を示している。
本実施の形態に係る施錠ロック装置２０は、遊技機１に設けられ、該遊技機１の前枠施錠機構１０の開錠時における動作を阻止し得るものである。
【００２４】
ここで先ず遊技機１は、ハンドル操作により遊技盤面上に球を打ち出し、各種役物への打球の入賞を競い楽しむパチンコ機である。図８に示すように、遊技機１は、箱状の外枠２と、外枠２に対し開閉可能に取り付けられる前枠３と、前枠施錠機構１０とを備えている。
【００２５】
外枠２の一側端にはヒンジ４が設けられており、このヒンジ４を介して遊技盤面を含む前枠３が開閉可能に取り付けられている。前枠施錠機構１０は、前枠３に変位可能に設けられた上下一対の鈎部材１１，１２と、外枠２に固設された上下一対の鈎受け１３，１４とを有する。
【００２６】
外枠２の一側端の内壁面には、上下に延びるスライド部材１５が、支持ブラケット１６を介して上下移動可能に設けられている。このスライド部材１５の上下部に、それぞれ前記鈎部材１１，１２が所定角度まで同期して回動可能に枢着されている。
【００２７】
鈎部材１１，１２は、スライド部材１５が下降位置に移動すると、鈎受け１３，１４と係合して前枠３が開かぬように施錠する状態（図３中実線で示す）に回動する一方、スライド部材１５が上昇位置に移動すると、鈎受け１３，１４から外れて前枠３が開くように開錠する状態（図３中点線で示す）まで回動するように設定されている。
【００２８】
スライド部材１５は、図示省略したバネによって通常時は下降位置に維持され、鈎部材１１，１２は鈎受け１３，１４に係合するが、鍵穴１７に差し込まれた鍵を回す手動操作によりスライド部材１５が上昇位置に移動すると、鈎部材１１，１２が鈎受け１３，１４から外れて開錠するように前枠施錠機構１０は構成されている。
【００２９】
このような前枠施錠機構１０を備えた遊技機１に、本発明に係る施錠ロック装置２０は設けられている。図７及び図８に示すように、施錠ロック装置２０は、そのロック部材３０が前記前枠施錠機構１０の鈎部材１２に係脱し得るように、外枠２の一側端の内壁面に設けられている。
【００３０】
施錠ロック装置２０は、ケース２１と、ケース２１に内装されるロック部材３０、ストッパ部材４０、それに駆動手段５０等を具備して成る。ケース２１は、図５に示すように、各部品を内装する際は２分割できるようになっており、図６に示すように、一体に組み合わされた状態で、取付ブラケット２１ａを介して外枠２の適所に固設される。
【００３１】
ロック部材３０は、前記前枠施錠機構１０の開錠動作を直接阻止する部材であり、回転体３１と、該回転体３１の一端より半径方向に延出する係止片３２とから成る。回転体３１は、ケース２１内に形成されている収納部２２に内装されている。また、係止片３２は、ケース２１の上部に形成された開口部２４からケース２１の外部に突出している。
【００３２】
ロック部材３０の回転体３１にある軸受け部３３には、ケース２１側の枢支軸２３が貫通している。この枢支軸２３によってロック部材３０は、前記前枠施錠機構１０の開錠動作を直接阻止するロック位置と、前記前枠施錠機構１０の開錠動作を許容するロック解除位置とに回動可能に軸支されている。
【００３３】
図１に示すように、ロック部材３０がロック位置にあるとき、係止片３２は、鈎部材１２に係合して鈎部材１２の回動操作を阻止するように位置する。一方、図２に示すように、ロック部材３０がロック解除位置に回動すると、係止片３２は、鈎部材１２に係合せず鈎部材１２の回動操作を阻止しないよう位置する。
【００３４】
図５に示すように、ロック部材３０の回転体３１の側面には掛止ピン３４が突設され、同様にケース２１の適所にも掛止ピン２５が突設されており、各掛止ピン２５，３４間にバネ部材（第１付勢手段）２８が掛け渡されている。このバネ部材２８によって、ロック部材３０は通常は図１に示すロック位置にあるように付勢されている。また、ロック部材３０には、ガイド溝３５、被係合部３６、カム溝３７、係合ピン３８が設けられているが、これらについては後述する。
【００３５】
ストッパ部材４０は、前記ロック部材３０をロック解除位置に拘束し、またその拘束を解除可能な部材であり、略Ｌ字形に形成されている。ストッパ部材４０の中央にある枢支部４１には、ケース２１側の枢支ピン２６が貫通している。また、ストッパ部材４０の一端側には鈎状の係合部４２が設けられ、他端側には押圧部４３が設けられている。
【００３６】
ストッパ部材４０は、その枢支部４１に貫通した枢支ピン２６によって、前記ロック部材３０をロック解除位置に保持する拘束位置と、前記ロック部材３０をロック解除位置からロック位置に回動させ得る拘束解除位置とに回動可能に軸支されている。また、枢支ピン２６の先端側は、ロック部材３０に設けられたガイド溝３５に相対的に移動可能に嵌合している。ここでガイド溝３５は、ロック部材３０の回動中心である枢支軸２３を中心とする円弧形に形成され、前記枢支ピン２６との嵌合関係により、ロック部材３０とストッパ部材４０との相対的な位置関係を規制している。
【００３７】
また、ストッパ部材４０は、通常その係合部４２が、前記ロック部材３０に設けられている被係合部３６に係合する方向、すなわち拘束位置側に、バネ部材（第２付勢手段）２９によって付勢されている。ストッパ部材４０は、その係合部４２がロック部材３０の被係合部３６に係合することで、バネ部材２８の付勢力に抗して、ロック部材３０をロック解除位置に保持するものである。
【００３８】
図２に示すように、後述する駆動手段５０の動力により、ロック部材３０がバネ部材２８の付勢力に抗してロック位置に回動すると、ストッパ部材４０はバネ部材２９の付勢力により、その係合部４２が前記ロック部材３０の被係合部３６に係合する拘束位置に回動する。一方、図４に示すように、駆動手段５０の動力により、ストッパ部材４０がバネ部材２９の付勢力に抗して拘束解除位置に回動すると、係合部４２は被係合部３６から外れるように設定されている。
【００３９】
駆動手段５０は、前記ロック部材３０及びストッパ部材４０を選択的に駆動するものである。詳しく言えば、駆動手段５０は、一時給電される毎に、ロック部材３０をバネ部材２８の付勢力に抗してロック解除位置に回動させ、これに伴いストッパ部材４０がバネ部材２９の付勢力で拘束位置に回動する状態と、ストッパ部材４０をバネ部材２９の付勢力に抗して拘束解除位置に回動させ、これに伴いロック部材３０がバネ部材２８の付勢力によりロック位置に回動する状態とに交互に切り換える機構である。
【００４０】
具体的に言えば駆動手段５０は、給電されると作動するソレノイド５１と、該ソレノイド５１の動力を前記ロック部材３０及びストッパ部材４０に選択的に伝達する動力伝達機構とから成る。ソレノイド５１は、一時給電される毎に一往復運動するプランジャ５２を備えている。
【００４１】
ソレノイド５１に給電されていない通常時は、図１，３に示す如くプランジャ５２がバネ部材５３の付勢力により突出した状態に維持される。一方、ソレノイド５１に給電するとその間だけ励磁し、その電磁力でプランジャ５２が、図２，４に示す如くバネ部材５３の付勢力に抗して引っ張られ、没入した状態に維持される。
【００４２】
プランジャ５２の先端部には、連結ピン５４を介してリンク部材５５の基端部が回動可能に連結されている。リンク部材５５は、前記動力伝達機構の主要部を成すものであり、その先端部には、前記ロック部材３０のカム溝３７に対し相対的に移動可能に嵌合する係合ピン５７が突設されている。
【００４３】
動力伝達機構の一部を成す係合ピン５７とカム溝３７との嵌合関係により、ソレノイド５１の動力が、ロック部材３０及びストッパ部材４０に選択的に伝達される。すなわち、ソレノイド５１のプランジャ５２が一往復運動する度に、ロック部材３０に動力を伝達して、該ロック部材３０をロック解除位置に回動させる動作と、ストッパ部材４０に動力を伝達して、該ストッパ部材４０を拘束解除位置に回動させる動作とが交互に繰り返される。
【００４４】
前記カム溝３７は、ロック部材３０の回動中心である枢支軸２３を中心とする円弧状の円弧溝部３７ａと、この円弧溝部３７ａの一端より回動中心寄りに直線状に延びる直線溝部３７ｂとから成る。円弧溝部３７ａに前記係合ピン５７が相対的に移動可能に嵌合している際、かかる嵌合関係により、ロック部材３０がロック解除位置に回動するように動力が伝達される。一方、直線溝部３７ｂに前記係合ピン５７が相対的に移動可能に嵌合する際、かかる嵌合関係により、ストッパ部材４０が拘束解除位置に回動するように動力が伝達される。なお詳しくは後述する。
【００４５】
また、ケース２１の下部にはマイクロスイッチ５８が設けられている。マイクロスイッチ５８は、前記ロック部材３０がロック位置またはロック解除位置にあるかを検出するための位置検知手段であり、押圧されるとＯＮになる可動子５９を有している。この可動子５９は、ロック部材３０がロック解除位置にある際、ロック部材３０の一端部に突設されている係合ピン３８に押圧されてＯＮとなるように位置決めされている。
【００４６】
次に作用を説明する。
前述した施錠ロック装置２０によれば、図１に示すように、前枠施錠機構１０の開錠動作を阻止するセキュリティ状態では、ロック部材３０は、バネ部材２８の付勢力によりロック位置に保持されている。このときロック部材３０の係止片３２によって、鈎部材１２が鈎受け１４から外れる方向へ回動するのが規制されるため、図８に示す鍵穴１７に鍵を差し込んでも回すことができない。
【００４７】
このようにロック部材３０がロック位置にあるときは、前枠施錠機構１０の開錠動作が確実に規制されるため、例えば閉店後に悪意ある者が、合い鍵等を使って開錠操作を行おうとしても操作不能であり、前枠３を開けることができず、不正行為を確実に防止することができる。
【００４８】
また、図１に示すセキュリティ状態では、マイクロスイッチ５８の可動子５９は、ロック部材３０にある係合ピン３８に押圧されていない。従って、マイクロスイッチ５８はＯＦＦ状態のままであり、遊技店側は、前記ロック部材３０がロック位置にあることを電気信号の有無に基づき容易に確認することができる。
【００４９】
前記セキュリティ状態にて、駆動手段５０のソレノイド５１に一回ごく短時間給電すると、ソレノイド５１は一時的に励磁し、その電磁力でプランジャ５２が、図２に示すように、バネ部材５３の付勢力に抗して引っ張られて没入した状態になる。このような図１→図２の順で示すプランジャ５２の一没入動作に伴い、リンク部材５５が引っ張られ、このリンク部材５５の係合ピン５７がカム溝３７の円弧溝部３７ａの一端に嵌合している状態で、ロック部材３０がバネ部材２８の付勢力に抗してロック解除位置まで回動する。
【００５０】
図２に示すように、ロック部材３０のロック解除位置への回動に伴い、ストッパ部材４０はバネ部材２９の付勢力により拘束位置に回動する。すなわち、図１中では被係合部３６の外側に乗り上げていたストッパ部材４０の係合部４２が、図２に示す如く被係合部３６に食い込むように係合する。このストッパ部材４０との係合関係によって、ロック部材３０はロック解除位置に保持される。
【００５１】
駆動手段５０への一時的な給電が断たれると、直ぐに図２→図３の順で示すように、プランジャ５２はバネ部材５３の付勢力により再び突出する。このプランジャ５２の一突出動作に伴って、リンク部材５５は、その係合ピン５７がカム溝３７の円弧溝部３７ａに沿って移動しつつ、バネ部材５３と平行に延びた元の状態に復帰する。ところが前記ロック部材３０は、ストッパ部材４０との前述した係合関係によって、そのままバネ部材２８の付勢力に抗してロック解除位置に保持される。
【００５２】
このような図３に示すセキュリティ解除状態では、鈎部材１２が鈎受け１４から外れる方向へ回動することが可能となり、前枠施錠機構１０の鍵穴１７に鍵を差し込んで回す開錠動作が妨げられることはなく、前枠３は開閉自在となる。また、セキュリティ解除状態では、マイクロスイッチ５８の可動子５９は、ロック部材３０にある係合ピン３８に押圧されてＯＮ状態となる。それにより、遊技店側は、前記ロック部材３０がロック解除位置にあることを、マイクロスイッチ５８から出力されたＯＮ信号に基づき容易に確認することができる。
【００５３】
前記セキュリティ解除状態にて、再びソレノイド５１に一回ごく短時間給電すると、ソレノイド５１は一時的に励磁し、プランジャ５２が没入した状態になる。このような図３→図４の順で示すプランジャ５２の一没入動作に伴い、リンク部材５５が引っ張られて、その係合ピン５７は、今度はカム溝３７の直線溝部３７ｂ内を真っ直ぐ移動しつつ、ストッパ部材４０の押圧部４３を図３中にて反時計方向に押圧する。それにより、ストッパ部材４０の係合部４２がロック部材３０の被係合部３６から外れて、ストッパ部材４０はバネ部材２９の付勢力に抗して拘束解除位置まで回動する。
【００５４】
図４に示すように、ストッパ部材４０が拘束解除位置まで回動すると、ロック部材３０はバネ部材２８の付勢力によって図１に示すロック位置に回動する。かかるロック部材３０がロック位置に復帰した直後のタイミングで、駆動手段５０への一時的な給電が断たれる。すると図４→図１の順で示すように、プランジャ５２は再び突出し、このプランジャ５２の一突出動作に伴って、リンク部材５５は、その係合ピン５７がカム溝３７の直線溝部３７ｂの一端から円弧溝部３７ａの一端に沿って移動しつつ、バネ部材５３と平行に延びた元の状態に復帰する。
【００５５】
ロック部材３０は、給電が断たれた後も、バネ部材２８の付勢力や各部品の係合関係によりそのままロック位置に保持されて、前枠施錠機構１０は元のセキュリティ状態となる。このときマイクロスイッチ５８は再びＯＦＦ状態となり、遊技店側は、ロック部材３０がロック位置にあることを確認することができる。
【００５６】
以上のように、本施錠ロック装置２０によれば、駆動手段５０のソレノイド５１に給電するのは、前述したセキュリティ状態またはセキュリティ解除状態の何れか一方から他方に切り換える際の一時だけで済む。従って、長時間に亘る給電による発熱に対する特別な対策は不要であり、また消費電力も極力抑えることが可能となる。
【００５７】
なお、図９に示すように、前枠施錠機構１０の鈎部材１２を上方へ回動させて開錠操作する場合には、施錠ロック装置２０は、その係止片３２が下方を向いて鈎部材１２に上から係合するように外枠２に取り付けるとよい。また、本発明に係る施錠ロック装置の具体的構成は、図示した実施の形態に限定されるものではない。
【００５８】
【発明の効果】
本発明に係る施錠ロック装置によれば、前枠施錠機構を備えた既存の遊技機に付加するだけで、動力伝達機構によって、プランジャが一往復運動する度に、前記ロック部材に動力が伝達され、第１付勢手段の付勢力に抗してロック部材がロック解除位置に変位して、ストッパ部材が第２付勢手段の付勢力により拘束位置に変位する状態と、ストッパ部材に動力が伝達されると、第２付勢手段の付勢力に抗して該ストッパ部材が拘束解除位置に変位して、ロック部材が前記第１付勢手段の付勢力によりロック位置に変位する状態とに交互に切り替えることができるので前枠施錠機構の開錠動作を規制することができ、手動でこの開錠時操作を行おうとしても操作不能となり、前枠を開けることができず、不正行為を確実に防止することができる。
【００５９】
しかも、動力伝達機構に給電するのは、セキュリティ状態またはセキュリティ解除状態の何れか一方から他へと切り換える際の一時だけで済むから、長時間に亘る給電による発熱に対する特別な対策は不要となり、また消費電力も極力抑えることが可能となる。それによりコストを低減することができる。

BACKGROUND OF THE INVENTION
The present invention is provided in a gaming machine having a front frame attached to an outer frame so as to be openable and closable, and a front frame locking mechanism that locks the front frame so as not to open and is manually unlocked. The present invention relates to a locking lock device that can prevent an unlocking operation of a front frame locking mechanism.
[0002]
[Prior art]
Conventionally, a gaming machine such as a pachinko machine has a front frame that can be opened and closed on the front side of a box-shaped outer frame, and when the front frame is opened, various accessories and nails on the game board surface can be adjusted. It can be done. The gaming machine is provided with a front frame locking mechanism that locks the front frame so as not to open and is unlocked by manual operation.
[0003]
Generally, when the front frame is closed, the front frame locking mechanism is configured such that the hook member provided on the front frame side engages with the hook receiver provided on the outer frame side, and is provided on the front frame side. When the key is inserted into the keyhole and turned, the hook member is released from the hook receiver and unlocked, and the front frame can be opened.
[0004]
[Problems to be solved by the invention]
However, since the front frame locking mechanism of the conventional gaming machine described above can easily open the front frame only by manual operation using a key, it is not comparable to a malicious person opening the front frame with a matching key etc. It was difficult to prevent fraudulent acts such as deliberately changing the control infrastructure etc. arranged on the back side of the gaming machine.
[0005]
In order to prevent such illegal acts, recently, an electric locking device that can be locked more severely than the front frame locking mechanism and cannot be unlocked only by a mechanical operation based on manual operation has been developed. Such an electric locking device is provided with an opening / closing control mechanism that, for example, restrains the front frame to a closed state when power is cut off after closing the store, and permits opening / closing of the front frame only during the business hours when power is supplied. Composed.
[0006]
However, when the existing locking mechanism is removed one by one and a new electric locking device is attached, a large-scale renovation work is required, and there is a problem that a great cost is required. Moreover, in the electric locking device, since it is necessary to continue power supply while allowing the opening and closing of the front frame to be permitted, it is necessary to separately take measures against heat generation based on power supply, and furthermore, it is difficult to reduce costs due to extra power consumption. The problem of becoming.
[0007]
The present invention has been made paying attention to the problems of the prior art as described above, and can be illegally unlocked with respect to the front frame locking mechanism only by adding it to a gaming machine equipped with an existing front frame locking mechanism. An object of the present invention is to provide a lock-and-lock device capable of suppressing power consumption and heat generation in spite of being an electric type that can reliably prevent operation and can be reliably operated and controlled.
[0008]
[Means for Solving the Problems]
  The gist of the present invention for achieving the above-described object resides in the following items.
[1] A front frame (3) attached to the outer frame (2) so as to be openable and closable, and a front frame locking mechanism (10) that locks the front frame (3) so as not to open and is unlocked by manual operation. A locking and locking device (20) that is provided in a gaming machine (1) that can prevent the unlocking operation of the front frame locking mechanism (10),
  A lock member (30) for preventing the unlocking operation of the front frame locking mechanism (10), a stopper member (40) capable of restraining and releasing the lock member (30), the lock member (30) and the stopper Drive means (50) for selectively driving the member (40),
  The lock member (30) can be displaced between a lock position that directly prevents the unlocking operation of the front frame locking mechanism (10) and a lock release position that allows the unlocking operation of the front frame locking mechanism (10). Provided in
  First urging means (28) for urging the lock member (30) toward the lock position, and second urging means (29) for urging the stopper member (40) toward the restraint position. ,
  The drive means (50) includes a solenoid (51) that operates when power is supplied, and a power transmission mechanism (selectively transmitting power of the solenoid (51) to the lock member (30) and the stopper member (40)). 55) and
  The solenoid (51) includes a plunger (52) that reciprocates once each time power is temporarily supplied.
  The power transmission mechanism transmits power to the lock member (30) each time the plunger (52) reciprocates once, and resists the biasing force of the first biasing means (28). (30) is displaced to the unlocked position, and the stopper member (40) is displaced to the restrained position by the urging force of the second urging means (29), and power is transmitted to the stopper member (40). Then, the stopper member (40) is displaced to the restraint release position against the urging force of the second urging means (29), and the lock member (30) is moved to the first urging means (28). ), And is alternately switched to a state of being displaced to the lock position.(20).
[0009]
[2]The stopper member (40) is provided with an engaging portion (42),
  When the locking member (30) is in the unlocking position, the engaging portion (42) is engaged with the locking member (30), and when the stopper member (40) is in the restraining releasing position, the engagement is performed. An engaged portion (36) from which the portion (42) is disengaged;
  When the engaging portion (42) is engaged with the engaged portion (36), the lock member (30) is brought into the unlocked position against the urging force of the first urging means (28). The locking lock device (20) according to [1], which is set to be held.

As shown in FIG. 6, the case 21 is integrally assembled with the outer frame via the mounting bracket 21 a. 2 fixed in place.
[0031]
The lock member 30 is a member that directly blocks the unlocking operation of the front frame locking mechanism 10, and includes a rotating body 31 and a locking piece 32 that extends in the radial direction from one end of the rotating body 31. The rotating body 31 is housed in a storage portion 22 formed in the case 21. Further, the locking piece 32 protrudes to the outside of the case 21 from an opening 24 formed in the upper part of the case 21.
[0032]
The pivot shaft 23 on the case 21 side passes through the bearing portion 33 in the rotating body 31 of the lock member 30. By this pivot shaft 23, the lock member 30 can be rotated between a lock position that directly prevents the unlocking operation of the front frame locking mechanism 10 and a lock release position that permits the unlocking operation of the front frame locking mechanism 10. Is pivotally supported.
[0033]
As shown in FIG. 1, when the lock member 30 is in the lock position, the locking piece 32 is positioned so as to engage with the flange member 12 and prevent the rotation operation of the flange member 12. On the other hand, as shown in FIG. 2, when the lock member 30 is rotated to the unlocked position, the locking piece 32 is positioned so as not to engage the flange member 12 and prevent the rotation operation of the flange member 12.
[0034]
As shown in FIG. 5, a latch pin 34 projects from the side surface of the rotating body 31 of the lock member 30. Similarly, a latch pin 25 projects from an appropriate position of the case 21. A spring member (first urging means) 28 is stretched between 25 and 34. By this spring member 28, the lock member 30 is normally biased so as to be in the lock position shown in FIG. Further, the lock member 30 is provided with a guide groove 35, an engaged portion 36, a cam groove 37, and an engagement pin 38, which will be described later.
[0035]
The stopper member 40 is a member that restrains the lock member 30 at the unlocking position and can release the restraint, and is formed in a substantially L shape. A pivot pin 26 on the case 21 side passes through the pivot portion 41 in the center of the stopper member 40. Further, a hook-like engaging portion 42 is provided on one end side of the stopper member 40, and a pressing portion 43 is provided on the other end side.
[0036]
The stopper member 40 has a restraining position for holding the lock member 30 in the unlocked position and a restraint capable of rotating the lock member 30 from the unlocked position to the locked position by the pivot pin 26 penetrating the pivot support portion 41. It is pivotally supported to the release position so as to be rotatable. The distal end side of the pivot pin 26 is fitted in a guide groove 35 provided in the lock member 30 so as to be relatively movable. Here, the guide groove 35 is formed in an arc shape centering on the pivot shaft 23 which is the rotation center of the lock member 30, and the lock member 30 and the stopper member 40 are brought into engagement with the pivot pin 26. The relative positional relationship is restricted.
[0037]
Further, the stopper member 40 has a spring member (second biasing means) in the direction in which the engaging portion 42 is normally engaged with the engaged portion 36 provided in the lock member 30, that is, in the restraining position side. 29 is energized. The stopper member 40 holds the lock member 30 in the unlocked position against the urging force of the spring member 28 by engaging the engaged portion 42 with the engaged portion 36 of the lock member 30. is there.
[0038]
As shown in FIG. 2, when the lock member 30 is rotated to the lock position against the urging force of the spring member 28 by the power of the driving means 50 described later, the stopper member 40 is moved by the urging force of the spring member 29. The engaging portion 42 is rotated to a restraining position where the engaging portion 42 engages with the engaged portion 36 of the lock member 30. On the other hand, as shown in FIG. 4, when the stopper member 40 is rotated to the restraint release position against the urging force of the spring member 29 by the power of the driving means 50, the engaging portion 42 is disengaged from the engaged portion 36. Is set to
[0039]
The drive means 50 selectively drives the lock member 30 and the stopper member 40. More specifically, the drive means 50 rotates the lock member 30 to the unlock position against the urging force of the spring member 28 every time power is supplied, and the stopper member 40 is attached to the spring member 29 accordingly. The stopper member 40 is rotated to the restraint release position against the biasing force of the spring member 29 and the lock member 30 is moved to the lock position by the biasing force of the spring member 28. It is a mechanism that switches alternately to a rotating state.
[0040]
Specifically, the drive means 50 includes a solenoid 51 that operates when power is supplied, and a power transmission mechanism that selectively transmits the power of the solenoid 51 to the lock member 30 and the stopper member 40. The solenoid 51 includes a plunger 52 that reciprocates once every time power is supplied.
[0041]
During normal times when power is not supplied to the solenoid 51, the plunger 52 is maintained in a state of protruding by the biasing force of the spring member 53 as shown in FIGS. On the other hand, when power is supplied to the solenoid 51, the solenoid 51 is excited only during that time, and the plunger 52 is pulled against the urging force of the spring member 53 as shown in FIGS.
[0042]
A proximal end portion of a link member 55 is rotatably connected to a distal end portion of the plunger 52 via a connecting pin 54. The link member 55 constitutes a main part of the power transmission mechanism, and an engagement pin 57 that fits movably relative to the cam groove 37 of the lock member 30 is provided at the tip thereof. Has been.
[0043]
The power of the solenoid 51 is selectively transmitted to the lock member 30 and the stopper member 40 due to the fitting relationship between the engagement pin 57 and the cam groove 37 forming a part of the power transmission mechanism. That is, every time the plunger 52 of the solenoid 51 reciprocates once, the power is transmitted to the lock member 30 and the lock member 30 is rotated to the unlock position, and the power is transmitted to the stopper member 40. The operation of rotating the stopper member 40 to the restraint release position is repeated alternately.
[0044]
The cam groove 37 includes an arcuate arc groove part 37a centering on the pivot shaft 23, which is the rotation center of the lock member 30, and a linear groove part 37b extending linearly from one end of the arc groove part 37a toward the rotation center. It consists of. When the engagement pin 57 is fitted to the arc groove 37a so as to be relatively movable, power is transmitted so that the lock member 30 is rotated to the unlock position by the fitting relationship. On the other hand, when the engagement pin 57 is fitted in the linear groove portion 37b so as to be relatively movable, power is transmitted so that the stopper member 40 is rotated to the restraint release position by the fitting relationship. Details will be described later.
[0045]
A micro switch 58 is provided below the case 21. The micro switch 58 is a position detecting means for detecting whether the lock member 30 is in the locked position or the unlocked position, and has a movable element 59 that is turned ON when pressed. When the lock member 30 is in the unlocked position, the mover 59 is positioned so as to be turned on by being pressed by the engagement pin 38 protruding from one end of the lock member 30.
[0046]
Next, the operation will be described.
According to the locking lock device 20 described above, as shown in FIG. 1, in the security state in which the unlocking operation of the front frame locking mechanism 10 is prevented, the lock member 30 is held in the locked position by the urging force of the spring member 28. ing. At this time, the locking piece 32 of the lock member 30 restricts the hook member 12 from rotating in the direction away from the hook receiver 14, so that it cannot be turned even if a key is inserted into the key hole 17 shown in FIG.
[0047]
Thus, when the lock member 30 is in the locked position, the unlocking operation of the front frame locking mechanism 10 is reliably restricted, so that, for example, a malicious person performs an unlocking operation using a key or the like after closing the store. However, the operation is impossible, the front frame 3 cannot be opened, and illegal acts can be surely prevented.
[0048]
Further, in the security state shown in FIG. 1, the mover 59 of the micro switch 58 is not pressed by the engagement pin 38 on the lock member 30. Accordingly, the micro switch 58 remains in the OFF state, and the game store side can easily confirm that the lock member 30 is in the lock position based on the presence or absence of an electrical signal.
[0049]
In the security state, when power is supplied to the solenoid 51 of the driving unit 50 for a very short time, the solenoid 51 is temporarily excited, and the plunger 52 is attached to the spring member 53 as shown in FIG. Being pulled and immersive against the power. 1 and FIG. 2, the link member 55 is pulled along with the immersion operation of the plunger 52, and the engagement pin 57 of the link member 55 is fitted to one end of the arc groove portion 37a of the cam groove 37. In this state, the lock member 30 rotates to the unlock position against the urging force of the spring member 28.
[0050]
As shown in FIG. 2, the stopper member 40 is rotated to the restraining position by the urging force of the spring member 29 as the lock member 30 is rotated to the unlocked position. That is, in FIG. 1, the engaging portion 42 of the stopper member 40 riding on the outside of the engaged portion 36 engages with the engaged portion 36 as shown in FIG. Due to the engagement relationship with the stopper member 40, the lock member 30 is held in the unlocked position.
[0051]
As soon as the temporary power supply to the drive means 50 is cut off, the plunger 52 projects again by the biasing force of the spring member 53 as shown in the order of FIG. As the plunger 52 protrudes, the link member 55 returns to the original state where the engaging pin 57 extends in parallel with the spring member 53 while moving along the arc groove portion 37a of the cam groove 37. . However, the lock member 30 is held in the unlocked position as it is against the biasing force of the spring member 28 due to the above-described engagement relationship with the stopper member 40.
[0052]
In such a security release state shown in FIG. 3, the hook member 12 can be rotated in a direction away from the hook receiver 14, and the unlocking operation of inserting and turning the key into the key hole 17 of the front frame locking mechanism 10 is hindered. The front frame 3 can be freely opened and closed. Further, in the security release state, the mover 59 of the micro switch 58 is pressed by the engagement pin 38 in the lock member 30 and is turned on. Thereby, the game store side can easily confirm that the lock member 30 is in the unlock position based on the ON signal output from the micro switch 58.
[0053]
When the power is once again supplied to the solenoid 51 again for a short time in the security release state, the solenoid 51 is temporarily excited and the plunger 52 is immersed. 3 and FIG. 4, the link member 55 is pulled in accordance with the one-immersion operation of the plunger 52 shown in the order of FIG. 3, and the engaging pin 57 moves straightly in the linear groove portion 37 b of the cam groove 37. Meanwhile, the pressing portion 43 of the stopper member 40 is pressed counterclockwise in FIG. Thereby, the engaging portion 42 of the stopper member 40 is disengaged from the engaged portion 36 of the lock member 30, and the stopper member 40 rotates to the restraint releasing position against the urging force of the spring member 29.
[0054]
As shown in FIG. 4, when the stopper member 40 is rotated to the restraint release position, the lock member 30 is rotated to the lock position shown in FIG. 1 by the urging force of the spring member 28. Temporary power supply to the drive means 50 is cut off immediately after the lock member 30 returns to the lock position. Then, as shown in the order of FIG. 4 → FIG. 1, the plunger 52 protrudes again, and the link pin 55 has one end of the linear groove portion 37 b of the cam groove 37 with the engaging pin 57 as the plunger 52 projects one time. To the original state extending in parallel with the spring member 53 while moving along one end of the arc groove portion 37a.
[0055]
Even after the power supply is cut off, the lock member 30 is held in the locked position as it is due to the urging force of the spring member 28 and the engagement relationship of each component, and the front frame locking mechanism 10 is in the original security state. At this time, the micro switch 58 is turned off again, and the game store side can confirm that the lock member 30 is in the lock position.
[0056]
As described above, according to the present locking / locking device 20, power supply to the solenoid 51 of the driving means 50 is only required at the time of switching from one of the security state or the security release state to the other. Therefore, no special measures against heat generation due to power supply over a long period of time are unnecessary, and power consumption can be suppressed as much as possible.
[0057]
As shown in FIG. 9, when the locking member 20 of the front frame locking mechanism 10 is rotated upward to perform the unlocking operation, the locking lock device 20 has the locking piece 32 facing downward. The member 12 may be attached to the outer frame 2 so as to be engaged from above. Further, the specific configuration of the locking lock device according to the present invention is not limited to the illustrated embodiment.
[0058]
【The invention's effect】
  According to the locking lock device according to the present invention, just by adding to an existing gaming machine equipped with a front frame locking mechanism,Whenever the plunger reciprocates once by the power transmission mechanism, power is transmitted to the lock member, the lock member is displaced to the unlock position against the biasing force of the first biasing means, and the stopper member is moved to the first position. 2 When the urging force of the urging means is displaced to the restraining position and when power is transmitted to the stopper member, the stopper member is displaced to the restraining release position against the urging force of the second urging means, Since the lock member can be alternately switched to the state of being displaced to the lock position by the biasing force of the first biasing means.The unlocking operation of the front frame locking mechanism can be restricted, and even if it is attempted to perform the unlocking operation manually, it becomes impossible to operate, the front frame cannot be opened, and illegal acts can be reliably prevented. .
