【０００１】
【発明の属する技術分野】
本発明は、パチンコ機の前面枠を本体枠に対し施錠すると共に、前面枠内に開閉可能に取り付けられたガラス枠を、前面枠に対し施錠するパチンコ機の施錠装置に関する。
【０００２】
【従来の技術】
パチンコ機の前面枠を本体枠に対し施錠する施錠装置として、断面Ｌ字状の取付板と支持板からなる基枠体の内側に、連結杆が摺動可能に配設され、支持板の上部と下部に鉤部材が連結杆に連結されて傾動可能に枢支され、取付板の中間部にシリンダ錠がその錠軸を取付板に設けた孔から内側に差込むように固定され、錠軸の先端に連結杆と係合するカム板が固定されてなる施錠装置が、一般に使用されている（例えば、実公昭５７−８８６７号公報等参照）。
【０００３】
【発明が解決しようとする課題】
一方、パチンコ機の前面枠内には、金枠が取付けられ、その金枠の上部に盤面を覆うガラス枠が開閉可能に取付けられているが、この種の施錠装置には、ガラス枠を施錠する施錠するガラス枠用施錠具は設けられてなく、単にガラス枠用施錠具を解錠するための作動片付き作動杆が、施錠装置の基枠体内に設けられ、シリンダ錠によるカム板の回動によりその作動杆を摺動させる機構が設けられるのみである。
【０００４】
このため、ガラス枠用施錠具を別個に前面枠の内側に取り付ける必要があり、その際の取付作業に多くの工数がかかると共に、施錠装置側の作動片をガラス枠用施錠具側の受け具にあわせるよう、位置調整を行なう必要があり、取付時の調整作業にも多くの作業工数がかかる問題があった。
【０００５】
そこで、本発明者らは、従来、特開平７−２０４３３７号公報において、１つの基枠体内に前面枠用の施錠装置とガラス枠用の施錠装置を組み込んだ施錠装置を提案した。
【０００６】
この施錠装置は、支持板の外側の上部と下部に、ガラス枠施錠用の鉤部材を傾動可能に枢支し、両鉤部材をガラス枠施錠用の連結杆により連結すると共に、シリンダ錠の錠軸に固定したカム板の係合部の一方をそのガラス枠施錠用連結杆に係合させ、カム板の他方の係合部を前面枠施錠用の連結杆に係合させる構造であった。したがって、従来のこの種の施錠装置は、１つの基枠体内に前面枠施錠用の連結杆とガラス枠施錠用の連結杆の両方が摺動可能に配設される構造のため、構造が複雑化し、部品点数も多くなる課題があった。
【０００７】
本発明は、上記の課題を解決するためになされたもので、構造が簡単で、部品点数が少なく、前面枠とガラス枠の施錠と解錠を円滑に行うことができるパチンコ機の施錠装置を提供することを目的とする。
【０００８】
【課題を解決するための手段】
上記の目的を達成するために、本発明の施錠装置は、取付板と支持板を有する縦長の基枠体と、基枠体の取付板に固定され、基枠体内に位置する錠軸にカム板を取り付けてなるシリンダ錠と、本体枠側に固定された受け金具に係止されて前面枠を施錠する前面枠鉤部材を有し、シリンダ錠による該カム板の一方向への回動に係合して前面枠鉤部材を解錠方向に動かす前面枠施錠機構と、ガラス枠側の係止片に係止されてガラス枠を施錠するガラス枠鉤部材を有し、シリンダ錠によるカム板の他方向への回動に係合してガラス枠鉤部材を解錠方向に動かすガラス枠施錠機構と、を備え、前面枠の内側に縦に取り付けられ、本体枠に対し前面枠を施錠し、前面枠に対しガラス枠を施錠するパチンコ機の施錠装置において、
基枠体の支持板に前面枠施錠用の前面枠鉤部材が傾動可能に枢支され、前面枠鉤部材には施錠方向に付勢するコイルばねが掛止され、支持板にガラス枠施錠用のガラス枠鉤部材が傾動可能に枢支され、ガラス枠鉤部材には施錠方向に付勢するコイルばねが取り付けられ、前面枠鉤部材とガラス枠鉤部材を解錠方向にのみ動かすための前面枠兼ガラス枠解錠用作動杆が支持板に沿って摺動可能に配設され、前面枠兼ガラス枠解錠用作動杆の一部にカム板が係合可能な係合孔が設けられたことを特徴とする。
【０００９】
ここで、上記施錠装置においては、請求項２のように、前面枠鉤部材とガラス枠鉤部材が各々枢支ピンにより支持板の各々の箇所に枢支され、前面枠兼ガラス枠解錠用作動杆には枢支ピンに係合してガイドされるガイド孔が設けられ、前面枠鉤部材とガラス枠鉤部材には各々係合凸部が設けられ、係合凸部に係合する係合部が前面枠兼ガラス枠解錠用作動杆の各々の箇所に設けられ、前面枠兼ガラス枠解錠用作動杆を一方向に移動させたとき、係合部と係合凸部を介して前面枠鉤部材が回動力を受けて解錠側に傾動して前面枠が解錠し、前面枠兼ガラス枠解錠用作動杆を他方向に移動させたとき、係合部と係合凸部を介してガラス枠鉤部材が回動力を受けて解錠側に傾動してガラス枠が解錠するように構成することができる。
【００１０】
また、上記施錠装置においては、請求項３のように、前パネル用施錠杆が基枠体の長手に沿って摺動可能に配設され、前パネル用施錠杆には基枠体の取付板から前方に突き出すように前パネル用鉤部が突設され、前パネル用施錠杆には施錠側に付勢するコイルばねが掛止され、前パネル用施錠杆の一部に操作部が設けられ、前面枠内の下部に開閉可能に取付けられた前パネル側に係止片が設けられ、前パネル用鉤部が係止片に係止されて前パネルが施錠されるように構成することができる。
【００１１】
【作用】
このような構成のパチンコ機の施錠装置では、前面枠を本体枠に対し閉じると、前面枠鉤部材が本体枠側の受け金具に当り傾動（回動）して係止され、施錠状態となる。それを解錠する場合は、キーによってシリンダ錠を回し、カム板を回転させると、カム板が前面枠兼ガラス枠解錠用作動杆を前面枠の施錠方向に摺動させる。このとき、前面枠兼ガラス枠解錠用作動杆が係合部と係合凸部を介して前面枠鉤部材を解錠方向に傾動（回動）させる。これにより、本体枠の受け金具と前面枠鉤部材との係合が外れ、前面枠は解錠される。
【００１２】
一方、ガラス枠を閉じると、ガラス枠内の係止片が基枠体の取付板から突出したガラス枠鉤部材に当り、ガラス枠鉤部材が傾動して、ガラス枠鉤部材に係止片が係止され、ガラス枠は施錠状態となる。ガラス枠を解錠する場合は、シリンダ錠のキーを逆方向に回して、カム板を同方向に回動させ、カム板が前面枠兼ガラス枠解錠用作動杆を前面枠の解錠時とは反対方向に摺動させる。これにより、前面枠兼ガラス枠解錠用作動杆が係合部と係合凸部を介してガラス枠鉤部材を解錠方向に傾動させる。このガラス枠鉤部材の傾動によって、ガラス枠の係止片と鉤部材の係合が外れ、ガラス枠は解錠される。
【００１３】
請求項３のように、前パネル用施錠杆が本施錠装置に具備される場合、前パネルを開くときには、ガラス枠を開いた状態で、その開口部から前面枠内に手を入れ、施錠装置に取付けた前パネル用施錠杆を、その操作部を持って押し下げる。このとき、前パネル用施錠杆に突設された前パネル用鉤部が摺動し、それによって、前パネル側に設けた係止片との係合が外れ、前パネルが解錠され、開かれる。一方、前パネルを閉じると、前パネル内の係止片が基枠体の取付板から突出した前パネル用鉤部に当り、前パネル用鉤部が前パネル用施錠杆と共に摺動して係止片に係止され、前パネルは施錠状態となる。
【００１４】
このように、従来は前面枠解錠用の連結杆とガラス枠解錠用の連結杆又は作動杆の両方を基枠体内に摺動可能に配設していたが、本施錠装置では、前面枠兼ガラス枠解錠用作動杆が基枠体内に摺動可能に配設されるだけであるから、構造を簡単化できると共に、部品点数を少なくすることができる。また、前面枠鉤部材とガラス枠鉤部材は独立して傾動可能であるから、本体枠側の受け金具またはガラス枠側の係止片と係合した際、軽く円滑に傾動することができ、前面枠またはガラス枠を軽く閉めるだけで、軽い操作力で確実に施錠することができ、また、解錠操作も軽く行なうことができる。
【００１５】
【発明の実施の形態】
以下、本発明の実施例を図面に基づいて説明する。図１は施錠装置の正面図を、図２はその左側面図を、図３はその右側面図を、図４はその背面図を各々示し、図５、図６はその分解図を示している。
【００１６】
１は取付板２と支持板３を略直角に曲折して一体成形してなる縦長の基枠体で、基枠体１の支持板３の上部と下部に、前面枠鉤部材用の枢支部３ａ、３ｂがその部分のみを内側に入れるように分離して形成される。取付板２には複数の取付孔が穿設される。また、図１に示す如く、基枠体１の角部の上部と中間部の左側に、後述のガラス枠鉤部材１１、１２を前方に突出させるための開口部１ａ，１ｂが形成される。
【００１７】
枢支部３ａ，３ｂには、各々前面枠鉤部材４，５が基枠体１の背面側を向けて、且つ下方に傾動（回動）可能に、枢支ピン４ａ，５ａにより枢支される。前面枠鉤部材４，５は三角形頭部を有しその中間部に係合凹部を有して、フック状に形成されている。さらに、前面枠鉤部材４，５の元部には、解錠時に後述の前面枠兼ガラス枠解錠用作動杆６の係合部６４，６５が係合して解錠方向に押すための係合凸部４ｂ，５ｂが各々突設され、また、この係合凸部４ｂ，５ｂには、コイルばね９ａ，９ｂが施錠方向に付勢するように掛止される。
【００１８】
この前面枠鉤部材４，５は、前面枠２１を本体枠２０に対し施錠するためのものであるが、施錠する際には、各前面枠鉤部材４，５が独立してコイルばね９ａ，９ｂの付勢力に抗して傾動するのみであるから、前面枠２１を閉じた際、非常に小さい力で軽く鉤部材を傾動させて施錠することができる。また、各前面枠鉤部材４，５が独立して傾動するから、針金などを前面枠２１の隙間に差し込んで行なわれる不正解錠に対しては、何れか一方の鉤部材４，５を針金などで引っ掛けて、解錠方向に傾動させても、他方の鉤部材は解錠方向に動くことはないため、この種の不正解錠を防止することができる。
【００１９】
図５に示すように、前面枠兼ガラス枠解錠用作動杆６の上部と下部には、２対づつのガイド孔６０〜６３が形成される。それらのうち、ガイド孔６１，６３には、前面枠鉤部材４，５を枢支する枢支ピン４ａ，５ａが挿通され、基枠体１の内側に支持板３に沿って配設される前面枠兼ガラス枠解錠用作動杆６は、その枢支ピン４ａ，５ａとガイド孔６１，６３及びガイド孔６０，６２により、上下にガイド摺動可能に支持されている。また、この前面枠兼ガラス枠解錠用作動杆６の上部寄りには後述のシリンダ錠７のカム板８が係合するための係合孔６８，６９が形成される。
【００２０】
さらに、この前面枠兼ガラス枠解錠用作動杆６には後述のガラス枠鉤部材１１，１２の係合凸部１１ｂ，１２ｂと係合する係合部６６，６７がその上部と中間部に設けられ、この作動杆６によってこの係合凸部１１ｂ、１２ｂが下方に押されることにより、このガラス枠鉤部材１１，１２は解錠方向（下方）に傾動（回動）する。また、この前面枠兼ガラス枠解錠用作動杆６には後述の前パネル用作動杆１７との間にコイルばね１４が掛止され、前面枠兼ガラス枠解錠用作動杆６を非解錠位置つまり中立位置に保持する。
【００２１】
取付板２の上部寄りに、シリンダ錠７がその錠軸を孔から基枠体１の内側に挿入するように、ねじ又はかしめで固定される。シリンダ錠７の錠軸には第一係合部８ａと第二係合部８ｂを持つカム板８が固定される。図４の反時計方向にカム板８を回動させた場合、カム板の第一係合部８ａは前面枠兼ガラス枠解錠用作動杆６の係合孔６８に係合し、前面枠兼ガラス枠解錠用作動杆６を上方に摺動させ、前面枠鉤部材４，５の末部の係合凸部４ｂ、５ｂを上方に押して前面枠鉤部材４，５を下方に傾動させる。前面枠兼ガラス枠解錠用作動杆６と前パネル用作動杆１７間に掛けられたコイルばね１４は、前面枠兼ガラス枠解錠用作動杆６または前パネル用作動杆１７が解錠側に移動したとき、それらを復帰させる方向に付勢する。
【００２２】
さらに、基枠体１の上部と中間部の角部に設けられた開口部１ａ，１ｂから前方に突き出すように、ガラス枠を施錠するガラス枠鉤部材１１，１２が配置され、ガラス枠鉤部材１１，１２は、基枠体１内の支持板３の上部と中間部に、枢支ピン１１ａ，１２ａによって枢支されて傾動可能に取り付けられる。このガラス枠鉤部材１１，１２は、上向きの係合凹部を持ったフック状に形成され、図５に示すように、中間部に係合凸部１１ｂ、１２ｂが設けられる。上記前面枠兼ガラス枠解錠用作動杆６の係合部６６，６７によってこの係合凸部１１ｂ、１２ｂが下方に押されることにより、このガラス枠鉤部材１１，１２は解錠方向（下方）に傾動（回動）する。また、上部のガラス枠鉤部材１１には、コイルばね１５ａが掛止され、このコイルばね１５ａにより鉤部材１１は上側施錠方向に付勢される。下側のガラス枠鉤部材１２には、コイルばね１５ｂが掛止され、このコイルばね１５ｂにより鉤部材１２上側施錠方向に付勢される。
【００２３】
上下のガラス枠鉤部材１１，１２は、独立して傾動可能であり、ガラス枠が閉じられてそこに設けた係止片２６，２７が当たったとき、前面枠兼ガラス枠解錠用作動杆６の移動を伴わずに、下方に傾動して係止片２６，２７に係止される。
【００２４】
このガラス枠鉤部材１１，１２においても、上記と同様に、各鉤部材１１，１２が独立してコイルばね１５ａ，１５ｂの付勢力に抗して傾動するのみであるから、ガラス枠を閉じた際、非常に小さい力で鉤部材１１，１２を傾動させて施錠することができる。また、各ガラス枠鉤部材１１，１２が独立して傾動するから、針金などをガラス枠の隙間に差し込んで行なわれる不正解錠に対しては、何れか一方の鉤部材を針金などで引っ掛けて、解錠方向に傾動させても、他方の鉤部材は解錠方向に動くことはないため、不正解錠を防止することができる。
【００２５】
さらに、基枠体１の下部には、図５、図６に示すように、後述の前パネル２８を施錠するための前パネル施錠機構が設けられる。前パネル施錠機構は、前パネル用作動杆１７とその上下動をガイドするガイドピン１７ｄ，１７ｅから構成され、基枠体１の支持板３の外側にガイドピン１７ｄ，１７ｅによって上下摺動可能に配設される。
【００２６】
図６に示すように、前パネル用作動杆１７にはその上部と下部に、前パネル用鉤部１８，１９が前方に突き出すように一体形成され、その前パネル用鉤部１８，１９は、先端部がフック状に形成され、基枠体１の取付板２から前方に突出して配設される。前パネル用作動杆１７には、２個のガイド孔１７ｂ，１７ｃが形成され、このガイド孔１７ｂ，１７ｃに、基枠体１の支持板２に取り付けたガイドピン１７ｄ，１７ｅが挿通され、ガイドピン１７ｄ，１７ｅとガイド孔１７ｂ、１７ｃを介して、支持板２の外側を所定の範囲で上下摺動可能に支持される。
【００２７】
前パネル用作動杆１７には、正面側の上部に操作部１７ａが設けられ、ガラス枠を開いた際、この操作部１７ａが正面側に現れるようにしている。また、作動杆１７の中間部には、検出部１７ｆが突設され、図示しない検出器（近接スイッチなど）を対向して配設することにより、前パネルの開放動作を電気的に検出する。さらに、この前パネル用作動杆１７には上記コイルばね１４が作動杆６との間に掛止され、施錠時または解錠時にはその復帰方向に付勢される。例えば、操作部１７ａを押し下げて、その付勢力に抗して前パネル用作動杆１７を下方に摺動させると、前パネル用鉤部１８，１９が下側の解錠方向に摺動した後、元の位置に復帰する。
【００２８】
このように構成されたパチンコ機の施錠装置は、図７、図８に示す如く、パチンコ機の本体枠２０に開閉可能に装着された前面枠２１の内側における矩形開口部の縁部に、シリンダ錠７の先端を前面に露出させ、前面枠鉤部材４，５を本体枠側に向けた姿勢で、取付板２を用いて縦に取付けられる。
【００２９】
一方、本体枠２０の内側の前面枠鉤部材４，５に対応した上下位置には、受け金具２４、２５が固定される。さらに、ガラス枠２２が、前面枠２１の開口部に内に取付けられた金枠内にヒンジを開閉可能に取付けられ、そのガラス枠２２の自由端部内側に、ガラス枠鉤部材１１，１２が係止可能な係止片２６、２７が設けられる。また、上皿などを設けた前パネル２８は、前面枠２１内の金枠の下部にヒンジを介して開閉可能取り付けられ、前パネル２８の自由端部内側に、前パネル用鉤部材１８，１９が係止可能な係止片２９，３０が設けられる。
【００３０】
パチンコ機における前面枠２１を本体枠２０に対し閉じると、図７に示すように、施錠装置の上下の前面枠鉤部材４，５が本体枠２０側の受け金具２４、２５に当って下方に傾動し、コイルばね９ａ，９ｂの付勢力により戻って係止され、施錠状態となる。このとき、前面枠鉤部材４，５は、各々が独立して傾動可能に枢支され、コイルばね９ａ，９ｂの付勢力に抗して傾動するのみであるから、前面枠２１を閉じた際、非常に小さい力で軽く前面枠鉤部材４，５を傾動させて施錠することができる。一方、施錠した状態では、各前面枠鉤部材４，５は独立して傾動するから、針金などを前面枠２１の隙間に差し込んで行なわれる不正解錠に対しては、何れか一方の鉤部材を針金などで引っ掛けて、解錠方向に傾動させても、他方の鉤部材は解錠方向に動くことはないため、この種の不正解錠を防止することができる。
【００３１】
前面枠２１を解錠する場合は、キーによってシリンダ錠７を回し、カム板８を図４の反時計方向に回転させると、カム板８の第一係合部８ａが前面枠兼ガラス枠解錠用作動杆６の係合孔６ａと係合してこれを上方へ摺動させる。このとき、図７のように、前面枠兼ガラス枠解錠用作動杆６の係合部６４，６５が前面枠鉤部材４，５の末端の係合凸部４ｂ、５ｂに係合して、前面枠鉤部材４，５を下方に傾動させる。この前面枠鉤部材４，５の傾動によって、本体枠の受け金具２４、２５との係合が外れ、前面枠２１は開放可能な状態となる。
【００３２】
一方、ガラス枠２２を前面枠２１の金枠内に閉じると、ガラス枠２２内の係止片２６、２７がガラス枠鉤部材１１，１２に当り、これを上方に傾動させながら閉じられ、コイルばね１４ａ，１４ｂの付勢力によりガラス枠鉤部材１１，１２が水平位置に戻る。これにより、ガラス枠鉤部材１１，１２に係止片２６、２７が係止され、ガラス枠２２は施錠状態となる。この場合も、ガラス枠鉤部材１１，１２は、各々が独立してコイルばね１４ａ，１４ｂの付勢力に抗して傾動するのみであるから、ガラス枠２２を閉じた際、非常に小さい力で軽くガラス枠鉤部材１１，１２を傾動させて施錠することができる。また、針金などによる不正解錠も防止することができる。
【００３３】
ガラス枠２２を解錠する場合は、図８に示すように、シリンダ錠７に差し込んだキーを左方向に回して、カム板８を図４時計方向へ回動させると、カム板８の第二係合部８ｂが前面枠兼ガラス枠解錠用作動杆６の係合孔６９と係合してこれを下方へ摺動させ、前面枠兼ガラス枠解錠用作動杆６の係合部６６，６７が鉤部材１１，１２の係合凸部１１ｂ、１２ｂに係合して、ガラス枠鉤部材１１，１２を下方へ傾動させる。この動作によって、ガラス枠２２の係止片２６、２７とガラス枠鉤部材１１，１２との係合が外れ、ガラス枠２２は開放される。
【００３４】
上皿等を前面に取付けた前パネル２８を開く場合、ガラス枠２２を開いた状態で、その開口部から内側に手を入れ、前パネル用作動杆１７の操作部１７ａを持って押し下げる。これによって、前パネル用作動杆１７が下降し、それと一体の前パネル用鉤部材１８，１９が下方に摺動する。これにより、前パネル用鉤部材１８，１９と前パネル側の係止片２９、３０との係合が外れ、前パネル２８が解錠され、開かれる。
【００３５】
前パネル２８を閉じる場合、前パネル２８を前面枠２１内に閉じるように押し込む。このとき、その係止片２９、３０が前パネル用鉤部材１８，１９の傾斜頭部に当たって、前パネル用鉤部材１８，１９を摺動させ、コイルばね１４の付勢力により元の位置に戻り、前パネル用鉤部材１８，１９に係止片２９、３０が係止され、前パネル２８は、施錠状態となる。
【００３６】
【発明の効果】
以上説明したように、本発明のパチンコ機の施錠装置によれば、１本の前面枠兼ガラス枠解錠用作動杆が基枠体の内側に摺動可能に配設されるだけであるから、従来の前面枠解錠用作動杆とガラス枠解錠用作動杆の両方を基枠体内に摺動可能に備えた施錠装置に比べ、部品点数を削減できる共に、それらのガイド構造なども１本の作動杆のみとなって、構造を簡単化することができる。
【００３７】
また、前面枠鉤部材とガラス枠鉤部材は、施錠時、独立してコイルばねの付勢力に抗して傾動するのみであるから、前面枠またはガラス枠を閉じた際、非常に小さい力で軽く鉤部材を傾動させて施錠することができる。また、前面枠鉤部材及びガラス枠鉤部材が独立して傾動するから、針金などを前面枠またはガラス枠の隙間に差し込んで行なわれる不正解錠に対しては、何れか一方の鉤部材を針金などで引っ掛けて、解錠方向に傾動させても、他方の鉤部材は解錠方向に動くことはないため、この種の不正解錠を防止することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a locking device for a pachinko machine for locking a front frame of a pachinko machine to a main body frame and for locking a glass frame openably and closably mounted in the front frame to the front frame.
[0002]
[Prior art]
As a locking device for locking the front frame of the pachinko machine with respect to the main body frame, a connecting rod is slidably disposed inside a base frame body including an L-shaped cross-section mounting plate and a support plate, and an upper portion of the support plate. A hook member is connected to the connecting rod at the lower part and pivotally supported pivotally, and a cylinder lock is fixed to an intermediate portion of the mounting plate so that the lock shaft is inserted inward from a hole provided in the mounting plate. A locking device in which a cam plate engaged with a connecting rod is fixed to the tip of the lock is generally used (for example, see Japanese Utility Model Publication No. 57-8867).
[0003]
[Problems to be solved by the invention]
On the other hand, a metal frame is mounted in the front frame of the pachinko machine, and a glass frame for covering the panel surface is mounted on the upper part of the metal frame so as to be openable and closable. No locking device for the glass frame to be locked is provided, and an operating rod with an operating piece for simply unlocking the locking device for the glass frame is provided in the base frame of the locking device, and rotation of the cam plate by the cylinder lock. Only a mechanism for sliding the operating rod is provided.
[0004]
For this reason, it is necessary to separately attach the glass frame locking device to the inside of the front frame, which requires a lot of man-hours for the mounting work, and the operating piece on the locking device side is replaced with the receiving member on the glass frame locking device side. Therefore, it is necessary to adjust the position so as to conform to the above, and there has been a problem that the adjustment work at the time of mounting also requires a lot of man-hours.
[0005]
In view of this, the present inventors have proposed a locking device in which a locking device for a front frame and a locking device for a glass frame are incorporated in one base frame in JP-A-7-204337.
[0006]
In this locking device, a hook member for locking a glass frame is pivotally supported on the upper and lower portions outside the support plate so as to be tiltable, and both hook members are connected by a connecting rod for locking the glass frame, and a lock for the cylinder lock is provided. One of the engaging portions of the cam plate fixed to the shaft is engaged with the connecting rod for locking the glass frame, and the other engaging portion of the cam plate is engaged with the connecting rod for locking the front frame. Therefore, this kind of conventional locking device has a complicated structure because both the connecting rod for locking the front frame and the connecting rod for locking the glass frame are slidably provided in one base frame. And the number of parts increases.
[0007]
The present invention has been made in order to solve the above problems, and has a simple structure, a small number of parts, and a locking device for a pachinko machine that can smoothly perform locking and unlocking of a front frame and a glass frame. The purpose is to provide.

As a result, the front panel operating rod 17 descends, and the front panel hook members 18, 19 integrated therewith slide downward. As a result, the engagement between the front panel hook members 18 and 19 and the front panel side locking pieces 29 and 30 is released, and the front panel 28 is unlocked and opened.
[0035]
When closing the front panel 28, the front panel 28 is pushed into the front frame 21 so as to be closed. At this time, the locking pieces 29, 30 hit the inclined heads of the front panel hook members 18, 19, and slide the front panel hook members 18, 19 to return to the original position by the urging force of the coil spring 14. The locking pieces 29, 30 are locked to the front panel hook members 18, 19, and the front panel 28 is in a locked state.
[0036]
【The invention's effect】
As described above, according to the pachinko machine locking apparatus of the present invention, only one front frame / glass frame unlocking operating rod is slidably disposed inside the base frame. The number of parts can be reduced as compared with a conventional locking device in which both a front frame unlocking operation rod and a glass frame unlocking operation rod are slidably provided in a base frame, and their guide structure and the like are one. With only the operating rod of the book, the structure can be simplified.
[0037]
Further, since the front frame hook member and the glass frame hook member only tilt independently against the urging force of the coil spring when locked, when the front frame or the glass frame is closed, a very small force is applied. The lock can be locked by slightly tilting the hook member. In addition, since the front frame hook member and the glass frame hook member are independently tilted, one of the hook members is connected to a wire against unauthorized unlocking performed by inserting a wire or the like into a gap between the front frame or the glass frame. Even if the hook member is hooked and tilted in the unlocking direction, the other hook member does not move in the unlocking direction, so this type of unauthorized unlocking can be prevented.
