Description

【０００１】
【発明の属する技術分野】
本発明は、前枠を外枠に開閉可能に支持したパチンコ遊技機、パチスロ遊技機等の遊技機において、前枠が閉じられたときにその前枠を外枠に係止するために用いられる施錠装置に関するものである。
【０００２】
【従来の技術】
従来より、パチンコ遊技機等の遊技機には、前枠を外枠に対し施錠するための施錠装置が組込まれている。施錠装置としては、枠体、上下一対の鉤部材、連結杆、シリンダ錠及びカム板を備えたものがよく知られている。枠体は前枠に取付けられ、両鉤部材は枠体の上下両端部に軸により支持されている。各鉤部材は軸を支点として傾動することにより、外枠に固定された受け金具に対し係止及び離脱する。連結杆は枠体に上下方向への往復動可能に配置され、その連結杆の上下両端部が前記鉤部材に連結されている。シリンダ錠は枠体に組込まれており、解錠に際し鍵が差込まれて回転操作される。カム板はシリンダ錠の錠軸に取付けられており、鍵の操作にともなう錠軸の回転を連結杆に伝達して、同連結杆を下方へ移動させる。
【０００３】
上記施錠装置によると、施錠時には、連結杆が上方に位置していて両鉤部材が受け金具に係止している。鍵が所定方向へ回されると、錠軸の回転がカム板を介して連結杆に伝わる。連結杆の下方への移動により、上下両鉤部材が同時に傾動してそれぞれ受け金具から離脱し、解錠される。このように、施錠装置は、鍵をシリンダ錠に差込んで回した場合に解錠される構造に設計されている。
【０００４】
【発明が解決しようとする課題】
ところで、パチンコホールのシマにおいては、多数台のパチンコ遊技機が横に列をなして並べられ、さらに隣合うパチンコ遊技機の間には玉貸し機が配置される。この玉貸し機の設置のために通常は、隣合うパチンコ遊技機が球貸し機の幅よりも多少広めの間隔で配置される。これにともない、パチンコ遊技機と球貸し機との間に若干の隙間が生ずる。そのため、針金等の線材を前記隙間を通じて差込み、鉤部材、特に下側の鉤部材に直接力を加えることが可能である。このようにして一方（下側）の鉤部材が傾動されると、その動きが連結杆を介して他方（上側）の鉤部材にも伝わってしまい、上下両鉤部材が連動して傾動し受け金具から離脱する。本来ならば、専用の鍵を用いなければ解錠できないはずの施錠装置が、その鍵を用いることなく不正に解錠されてしまう問題がある。
【０００５】
そこで、本発明は、鉤部材を線材等で不正に動かして解錠する不正解錠を確実に防止することのできる遊技機の施錠装置の提供を課題とするものである。
【０００６】
【課題を解決するための手段】
請求項１に記載の発明は、遊技機の前枠に設けられ、かつ鍵により解錠操作される錠と、前記前枠に設けられ、かつそれぞれ軸により傾動可能に支持され、その傾動により前記遊技機の外枠に設けられた複数の被係止部にそれぞれ係止及び離脱する、第１鉤部材及び第２鉤部材を少なくとも含む複数の鉤部材と、前記鍵の解錠操作に応じた前記錠の動作を複数の前記鉤部材に伝達して前記被係止部から離脱させる鍵解錠伝達機構と、前記第１鉤部材に対して前記鍵を用いずに行われる不正な解錠操作に応じた同第１鉤部材の動作が、前記不正な解錠操作がなされていない前記第２鉤部材に伝達されるのを遮断する第１伝達遮断機構と、前記第２鉤部材に対して前記鍵を用いずに行われる不正な解錠操作に応じた同第２鉤部材の動作が、前記不正な解錠操作がなされていない前記第１鉤部材に伝達されるのを遮断する第２伝達遮断機構とを有する施錠装置を備えた遊技機であって、
前記鍵解錠伝達機構及び前記第１伝達遮断機構は、少なくとも前記第１鉤部材に動力伝達可能に連結された第１連結杆と、少なくとも前記第２鉤部材に動力伝達可能に連結され、かつ前記鍵の解錠操作にともない解錠方向へ移動する第２連結杆と、前記第２連結杆から前記第１連結杆への動力伝達を許容し、前記第１連結杆から前記第２連結杆への動力伝達を遮断する第１伝達経路断続部とを備え、
さらに、前記第１伝達経路断続部は、前記第１連結杆及び前記第２連結杆の一方に設けられ、連結杆の長さ方向に沿って延びるガイド部と、前記第１連結杆及び前記第２連結杆の他方に設けられ、前記ガイド部内に往復動可能に係合された係合突部と、前記第１連結杆を反解錠方向へ付勢する第１弾性部材とを備え、
前記第２伝達遮断機構は、前記第２連結杆から前記第２鉤部材への動力伝達を許容し、該第２鉤部材から前記第２連結杆への動力伝達を遮断する第２伝達経路断続部を備え、
さらに、前記第２伝達経路断続部は、前記第２連結杆に設けられた押圧部と、前記第２鉤部材に設けられ、前記第２連結杆の解錠方向への移動にともない前記押圧部に当接し、前記第２鉤部材の前記不正な解錠操作にともない前記押圧部から離間する受圧部と、前記受圧部を前記押圧部に当接させる方向へ前記第２鉤部材を付勢する第２弾性部材とを備え、
前記不正な解錠操作によって前記第１鉤部材が前記被係止部から離脱しても、前記第２弾性部材の付勢力によって前記第２鉤部材が前記被係止部を係止するように構成され、前記不正な解錠操作によって前記第２鉤部材が前記被係止部から離脱しても、前記第１弾性部材の付勢力によって前記第１鉤部材が前記被係止部を係止するように構成されている。
【０００７】
上記発明によると、施錠時には、全ての鉤部材が被係止部に係止し、遊技機の前枠が閉じられた状態に保たれる。鍵を解錠操作すると、その操作に応じて錠が動作する。錠の動作は鍵解錠伝達機構を通じて全ての鉤部材に伝達され、それらの鉤部材が被係止部から離脱し、前枠が開放可能となる。一方、鍵を用いずに、線材等によって第１鉤部材に対し不正な解錠操作を行うと、その鉤部材は被係止部から離脱する（外れる）。しかし、第１鉤部材の動作は、第１伝達遮断機構の作用により、解錠操作されていない鉤部材の少なくとも１つには伝達されない。その結果、少なくとも１つの鉤部材は被係止部に係止した状態を維持し続け、前枠が開くことはない。
【０００８】
【発明の実施の形態】
（第１実施形態）
以下、本発明をパチンコ遊技機の施錠装置に具体化した第１実施形態を図面に従って説明する。図１及び図２に示すように、パチンコ遊技機１は、外枠２と、軸９により外枠２に開閉可能に支持された前枠（内枠と呼ばれることもある）３と、前枠３に組付けられた遊技盤４と、軸１０により前枠３に開閉可能に支持されたガラス枠５とを備えている。外枠２内の右側部には被係止部が固定されている。被係止部は、剛性の高い材料、例えば金属板によって形成されている。ここでは、被係止部として、金属板を曲げ形成したもの（以下「受け金具」という）が用いられ、これが木ねじ等によって外枠２に固定されている。受け金具の数は複数（２つ以上）であり、ここでは２個の受け金具（第１受け金具６及び第２受け金具７）が用いられている。第１受け金具６は外枠２の下部に固定され、第２受け金具７は外枠２の上部に固定されている。前枠３の裏面の右側部には、縦長の施錠装置８が組付けられている。施錠装置８は、前枠３が閉じられたときにその前枠３を外枠２に係止するための機構と、ガラス枠５が閉じられたときにそのガラス枠５を前枠３に係止するための機構とを備えている。本実施形態では、主として前者の機構について説明し、後者の機構については説明を省略する。
【０００９】
施錠装置８は、図３（ａ），（ｂ）に示すように上下に細長い枠体１３を備えており、この枠体１３において前枠３に固定されている。ここでは、金属板を略直角に曲げてアングル状としたものが枠体１３として用いられているが、これに限らない。枠体１３において互いに略直交する２つの板状部分を区別するために、一方を「取付け部１１」といい、他方を「支持部１２」ということにする。取付け部１１は木ねじ等の締結具によって前枠３の裏面に固定されており、支持部１２は同裏面に対し略直交している。枠体１３の上部には、補助枠３５が上下方向への往復動可能に取付けられている。補助枠３５は、ガラス枠５を前枠３に係止するための機構の一部をなすものである。
【００１０】
取付け部１１には、図４（ｂ）に示すように、解錠のために専用の鍵（以下「専用キー」という）１４によって解錠操作される錠が組付けられている。ここでは、錠としてシリンダ錠１５が用いられているが、これ以外のタイプの錠が用いられてもよい。シリンダ錠１５においては、解錠のために専用キー１４が差込まれて回転されるが、ここでは、パチンコ遊技機１の正面から見て時計回り方向（図４（ｂ）において矢印で示す方向）を、前枠３を開放する際に専用キー１４を回す方向とし、反時計回り方向を、ガラス枠５を開放する際に専用キー１４を回す方向としている。シリンダ錠１５は、前枠３にあけられた孔（図示略）に通されている。図３（ａ），（ｂ）に示すように、シリンダ錠１５は専用キー１４の操作にともない回動する錠軸１６を備えている。錠軸１６には、第１突起１７及び第２突起１８を有するカム板１９が取付けられている。
【００１１】
支持部１２の下部において、第１受け金具６と対応する箇所には、第１鉤部材２１が軸２２により上下方向への傾動可能に支持されている。第１鉤部材２１は、略水平状態となったときに第１受け金具６に係止し、下方へ傾いたときに同受け金具６から離脱する（外れる）。同様に、支持部１２の上部において、第２受け金具７と対応する箇所には、第２鉤部材２３が軸２４により上下方向への傾動可能に支持されている。第２鉤部材２３は略水平状態となったときに第２受け金具７に係止し、下方へ傾いたときに同受け金具７から離脱する（外れる）。なお、鉤部材２１，２３としては、上方へ傾いたときに受け金具６，７から離脱するタイプが用いられてもよいし、傾動以外の動作をして受け金具６，７に係止及び離脱するタイプが用いられてもよい。
【００１２】
支持部１２の側方（図３（ａ）では左方）近傍には、連結杆２０が上下方向への往復動可能に配置されている。枠体１３には、連結杆２０の前後方向の動き及び左右方向の動きを規制するための機構が設けられている。図３（ａ）においては、前後方向は矢印Ｘによって示され、左右方向は矢印Ｙによって示されている。前後方向の動きを規制する機構として、支持部１２の後部には所定数のガイド片２７が曲げ形成されており、これらのガイド片２７と取付け部１１とによって連結杆２０が挟み込まれている。左右方向の動きを規制する機構として、取付け部１１の裏面には所定数の規制突起２８が形成されており、これらの規制突起２８と支持部１２とによって連結杆２０が挟み込まれている。これらの規制のための機構は一例にすぎず、適宜変更可能である。なお、連結杆２０の上下方向への往復動のうち、上方への移動は解錠に関連する。後述するように、連結杆２０の上方への移動により、全鉤部材２１，２３が受け金具６，７から外れて、解錠が行われる。このことから、連結杆２０の往復動方向である上下方向のうち、「上方」を「解錠方向」というものとする。
【００１３】
連結杆２０は第１連結杆２５と、その上側に配置された第２連結杆２６とに分割されている。第１連結杆２５は上下に細長い形状をなし、その下端部において第１鉤部材２１に動力伝達可能に連結されている。ここでは、第１連結杆２５の下端部が、連結ピン２９により第１鉤部材２１に直接連結されている。このため、第１連結杆２５から第１鉤部材２１への動力伝達と、その逆方向の動力伝達とがともに可能である。
【００１４】
第２連結杆２６は上下に細長い形状をなし、その一部には、前記カム板１９の回転にともない第１突起１７が当接される回転伝達部３２が形成されている。これらのカム板１９及び回転伝達部３２は、錠軸１６の回転運動を直線運動に変換して第２連結杆２６に伝達するものである。そして、前枠３の開放のために専用キー１４が時計回り方向へ回されると、第１突起１７が回転伝達部３２に下側から当接し、第２連結杆２６を押上げる。このようにして、第２連結杆２６は専用キー１４の解錠操作にともない解錠方向へ移動する。これとは逆に、ガラス枠５の開放のために専用キー１４が反時計回り方向へ回されると、第２突起１８が補助枠３５を押し下げる。
【００１５】
第２連結杆２６の上端部は第２鉤部材２３に動力伝達可能に連結されている。しかし、同上端部は、前述した第１連結杆２５の下端部とは異なり、第２鉤部材２３に対し連結ピンによって連結されてはいない。連結ピンによる連結に代えて、第２連結杆２６の上端部には押圧部３３が設けられ、第２鉤部材２３には受圧部３４が設けられている。ここでは、第２連結杆２６の上端縁が押圧部３３として利用されている。第２鉤部材２３の一部は第２連結杆２６側へ曲げ形成されており、この折曲げ部分が受圧部３４とされている。これらの押圧部３３及び受圧部３４は一例にすぎず、専用キー１４の操作により第２連結杆２６が上方（解錠方向）へ移動したときには受圧部３４が押圧部３３に当接し、かつ第１鉤部材２１が不正に押下げられたときには受圧部３４が押圧部３３から離間するという条件を満たす限りにおいて、適宜変更可能である。この変更に際しては、押圧部３３は第２連結杆２６と一体で形成されてもよいし、別部材によって形成され、接着、溶接等の手段によって第２連結杆２６に固定されてもよい。受圧部３４に関しても同様である。
【００１６】
さらに、受圧部３４を押圧部３３に当接させる方向へ第２鉤部材２３を付勢する第２弾性部材が用いられている。ここでは、第２弾性部材として第２コイルばね３６が用いられ、これが引張られた状態で補助枠３５及び受圧部３４間に掛渡されている。第２コイルばね３６は、補助枠３５に代えて枠体１３に掛止されてもよい。第２弾性部材としては、圧縮コイルばね、ねじりコイルばね、板ばね、棒ばね等のばねが用いられたり、ばね以外のもの、例えばゴム（ゴム紐等）が用いられたりしてもよい。
【００１７】
第１連結杆２５及び第２連結杆２６は次のようにして伸縮可能に連結されている。連結杆２５，２６の一方には、その長さ方向に沿って延びるガイド部が設けられ、他方には係合突部が設けられ、この係合突部がガイド部内に往復動可能に係入されている。ここでは、ガイド部として、第２連結杆２６の下端部に上下方向に細長い長孔３７があけられている。また、係合突部として、第１連結杆２５の上端部に係合ピン３８が固定されている。そして、係合ピン３８が長孔３７内に係入されている。従って、係合ピン３８を長孔３７内でスライドさせることにより、連結杆２０が伸縮する。
【００１８】
なお、上記とは逆に、ガイド部が第１連結杆２５に設けられ、係合突部が第２連結杆２６に設けられてもよい。また、ガイド部としては、長孔に限らず溝であってもよい。さらに、第１連結杆２５を常に下方（反解錠方向）へ付勢する第１弾性部材が設けられている。ここでは、第１弾性部材として第１コイルばね３１が用いられ、これが引張られた状態で、取付け部１１及び第１連結杆２５に掛渡されている。第１弾性部材としては、圧縮コイルばね、ねじりコイルばね、板ばね、棒ばね等のばねが用いられたり、ばね以外のもの、例えばゴムが用いられたりしてもよい。
【００１９】
そして、第１連結杆２５と、回転伝達部３２を有する第２連結杆２６と、両連結杆２５，２６を伸縮可能に連結する長孔３７及び係合ピン３８と、第１連結杆２５を第１鉤部材２１に連結する連結ピン２９と、第２連結杆２６を第２鉤部材２３に動力伝達可能に連結する押圧部３３及び受圧部３４と、第１コイルばね３１及び第２コイルばね３６とは、鍵解錠伝達機構Ａ、第１伝達遮断機構Ｂ及び第２伝達遮断機構Ｃを構成している。これらの構成要素は、鍵解錠伝達機構Ａとして機能することにより、専用キー１４の解錠操作に応じたシリンダ錠１５の動作を全ての鉤部材２１，２３に伝達して受け金具６，７から外れさせる。第１伝達遮断機構Ｂとして機能することにより、第１鉤部材２１に対する解錠操作に応じた同鉤部材２１の動作が、解錠操作されていない第２鉤部材２３に伝達されるのを遮断する。第２伝達遮断機構Ｃとして機能することにより、第２鉤部材２３に対する解錠操作に応じた同鉤部材２３の動作が、解錠操作されていない第１鉤部材２１に伝達されるのを遮断する。
【００２０】
また、鍵解錠伝達機構Ａ及び第１伝達遮断機構Ｂの構成要素中、長孔３７、係合ピン３８及び第１コイルばね３１は、第２連結杆２６から第１連結杆２５への動力伝達を許容し、第１連結杆２５から第２連結杆２６への動力伝達を遮断するための第１伝達経路断続部Ｄを構成している。鍵解錠伝達機構Ａ及び第２伝達遮断機構Ｃの構成要素中、押圧部３３、受圧部３４及び第２コイルばね３６は、連結杆２０から第２鉤部材２３への動力伝達を許容し、第２鉤部材２３から連結杆２０への動力伝達を遮断するための第２伝達経路断続部Ｅを構成している。
【００２１】
前記の施錠装置８が組付けられたパチンコ遊技機１は、パチンコホールのシマにおいては、横に列をなして並べられる。図１に示すように、隣合うパチンコ遊技機１の間には二点鎖線で示すように縦長の球貸し機４１が配置される。
【００２２】
次に、前記のように構成された本実施形態の作用及び効果について説明する。図４（ａ）は、施錠装置８の施錠時の状態を示している。この状態では、第２コイルばね３６によって下方へ引張られた第２鉤部材２３が第２受け金具７に下側から係止している。受圧部３４により、第２連結杆２６の上方への移動が規制されている。また、回転伝達部３２に対し第１突起１７が下側から当接している。このため、第２連結杆２６は上下動不能である。第１連結杆２５においては、第１コイルばね３１による下方への引張り力が常に作用しているが、係合ピン３８が長孔３７の下端に当接しており、この当接により第１連結杆２５の下方への移動が規制されている。そして、第１連結杆２５の下端に連結された第１鉤部材２１は、第１受け金具６に下側から係止している。両鉤部材２１，２３の係止により前枠３が閉じられた状態に保たれている。
【００２３】
前枠３を開放するために、図４（ｂ），（ｃ）に示すように、専用キー１４をシリンダ錠１５に差込み、図４（ｂ）の矢印で示す方向へ回すと、錠軸１６及びカム板１９が同方向へ回転する。カム板１９の回転により第１突起１７が回転伝達部３２を通じて第２連結杆２６を押上げる。第２連結杆２６の動きは第２伝達経路断続部Ｅによって第２鉤部材２３に伝達される。詳しくは、第２連結杆２６の動きは押圧部３３、受圧部３４を通じて第２鉤部材２３に伝達される。第２鉤部材２３は第２コイルばね３６の引張り力に抗して下方へ傾動し、第２受け金具７から外れる。また、第２連結杆２６の動きは、第１伝達経路断続部Ｄにより第１連結杆２５に伝達される。詳しくは、第２連結杆２６の動きは、長孔３７の下端に位置する係合ピン３８を通じて第１連結杆２５に伝達される。第１連結杆２５は、第２連結杆２６と一体となって、第１コイルばね３１の引張り力に抗して上方へ移動する。この移動は連結ピン２９を通じて第１鉤部材２１に伝達され、同鉤部材２１が下方へ傾動し、第１受け金具６から外れる。このように、専用キー１４の解錠操作に応じてシリンダ錠１５が動作し、その動作が鍵解錠伝達機構Ａ、第１伝達経路断続部Ｄ及び第２伝達経路断続部Ｅの作用により、全ての鉤部材２１，２３に伝達される。それらの鉤部材２１，２３が略同時に受け金具６，７から外れ、前枠３の開放が可能となる。
【００２４】
一方、パチンコ遊技機１と球貸し機４１との間に若干の隙間が生じていることを利用し、専用キー１４を用いずに、線材等、例えば針金をその隙間下部を通じて差込み、図５（ａ）に示すように、第１鉤部材２１に直接力を加えて下方へ傾動させると、同第１鉤部材２１が第１受け金具６から外れる。しかし、第１鉤部材２１の動作は、第１伝達遮断機構Ｂ及び第１伝達経路断続部Ｄの作用により、解錠操作されていない第２鉤部材２３には伝達されない。詳しくは、第１鉤部材２１の傾動により第１連結杆２５が第１コイルばね３１に抗して上方（解錠方向）へ移動する。これにともない係合ピン３８は長孔３７の下端部から上方へ移動する。この移動により、第１連結杆２５から第２連結杆２６への動力伝達が遮断される。第１連結杆２５は移動するものの第２連結杆２６は動かず、結果として第２鉤部材２３は第２受け金具７に係止し続ける。前枠３は閉じたままである。
【００２５】
前記とは逆に、専用キー１４を用いずに、パチンコ遊技機１と球貸し機４１との間の隙間上部を通じて線材等を差込み、図５（ｂ）に示すように、第２コイルばね３６に抗して第２鉤部材２３に直接力を加えて下方へ傾動させると、同鉤部材２３が第２受け金具７から外れる。しかし、第２鉤部材２３の動作は、第２伝達遮断機構Ｃ及び第２伝達経路断続部Ｅの作用により、解錠操作されていない第１鉤部材２１には伝達されない。すなわち、第２鉤部材２３は下方へ傾動するものの、受圧部３４が押圧部３３から上方へ離間するのみで、第２鉤部材２３の動きは連結杆２０に伝達されない。結果として、両連結杆２５，２６は動かず、第１鉤部材２１は第１受け金具６に係止し続ける。前枠３は閉じたままである。
【００２６】
このように本実施形態によると、専用キー１４を解錠操作することにより全ての鉤部材２１，２３を受け金具６，７から外すようにした施錠装置８において、第１鉤部材２１を線材等で不正に動かして第１受け金具６から外しても、第２鉤部材２３が第２受け金具７から外れない。このため、従来の施錠装置とは異なり、不正解錠を防止することができる。
【００２７】
ところで、不正解錠を防止するほかの対策として、専用キーを用いて解錠操作を行った場合には全鉤部材が動き、それ以外の解錠操作を行った場合には鉤部材が動かないようにすることが考えられる。そのために、例えば、施錠完了時に連結杆の動きをロックするロック部材を連結杆に支持し、専用キーを用いた解錠操作を行った場合にのみロック部材のロックを解除するロック解除機構を設ける。このようにすれば、専用キーを用いた解錠操作時には、ロック解除機構の作用によりロック部材のロックが解除されて連結杆が移動し、鉤部材が傾動して受け金具から外れる。しかし、鉤部材を直接傾動させる不正解錠操作時には、ロック部材によりロックされた連結杆は動かず、全ての鉤部材が受け金具に係止し続ける。従って、不正解錠防止の点に関しては、本実施形態と同様の効果が得られる。
【００２８】
反面、上記の対策ではロック部材及びロック機構を含めた施錠装置全体の構造が複雑となり、また部品点数も多くなってしまう。これに対し、本実施形態では、上記のようなロック機構を付加していない。第１鉤部材２１から第２鉤部材２３への動力伝達を遮断するために、両連結杆２５，２６を長孔３７と係合ピン３８とによって伸縮可能に連結し、第２鉤部材２３から第１鉤部材２１への動力伝達を遮断するために、第２連結杆２６の一部を押圧部３３とし、第２鉤部材２３の一部に受圧部３４を形成しているのみである。これらの構造は非常に簡単であり、また部品点数も少ない。従って、本実施形態は、組付け作業性、メンテナンス、製造コスト等の面で上記対策に比べ優れている。
【００２９】
本実施形態は前述した事項以外にも次の特徴を有する。
（ａ）第１連結杆２５、第２連結杆２６及び第１伝達経路断続部Ｄという、少なくかつ簡単な構成で、鍵解錠伝達機構Ａ及び第１伝達遮断機構Ｂを成立させることができる。しかも、ガイド部、係合突部及び第１弾性部材という、少なくかつ簡単な構成で第１伝達経路断続部Ｄを成立させることができる。さらに、第１連結杆２５又は第２連結杆２６に対し打抜き等の簡単な加工を行うだけでガイド部（長孔３７）を設けることができる。
【００３０】
（ｂ）第２鉤部材２３に対する解錠操作に応じた同鉤部材２３の動作が、解錠操作されていない第１鉤部材２１に伝達されるのを遮断する第２伝達遮断機構Ｃを設けている。このため、第１鉤部材２１が不正に解錠操作された場合だけでなく、第２鉤部材２３が不正に解錠操作された場合にも、施錠装置８が解錠されるのを防止することができる。不正解錠をより一層確実に防止することができる。
【００３１】
（ｃ）連結杆２０（第１連結杆２５、第２連結杆２６）及び第２伝達経路断続部Ｅという、少なくかつ簡単な構成で、鍵解錠伝達機構Ａ及び第２伝達遮断機構Ｃを成立させることができる。しかも、押圧部３３、受圧部３４及び第２弾性部材という、少なくかつ簡単な構成で第２伝達経路断続部Ｅを成立させることができる。
【００３２】
（ｄ）第２連結杆２６の上端縁を押圧部３３として利用している。また、第２鉤部材２３の一部を折曲げることにより受圧部３４としている。このため、押圧部３３及び受圧部３４の形成のために、曲げ加工等の簡単な加工を行うだけですむ。

（第２実施形態）
次に、本発明を具体化した第２実施形態を図６（ａ），（ｂ）に従って説明する。第２実施形態は、第２伝達遮断機構Ｃに代えて鉤部材解錠伝達機構Ｆを備えている点において第１実施形態と大きく異なっている。鉤部材解錠伝達機構Ｆは、第２鉤部材２３に対する解錠操作に応じた同鉤部材２３の動作を、解錠操作されていない第１鉤部材２１にも伝達するためのものであり、前述した第１伝達経路断続部Ｄを含んでいる。詳しくは、第１実施形態において、第１鉤部材２１が第１連結杆２５に対し連結ピン２９によって連結されているのと同様にして、第２鉤部材２３が第２連結杆２６に対し連結ピン４２によって連結されている。押圧部３３及び受圧部３４は省略されている。受圧部３４の省略にともない、第２コイルばね３６の一端（上端）は第２連結杆２６の上端部に掛止されている。なお、第１実施形態と同様の部材については同一の符号を付して説明を省略する。
【００３４】
本実施形態において、専用キー１４を用いて解錠操作を行った場合の各部の動きは第１実施形態と略同様である。第１実施形態との違いは、第２連結杆２６から第２鉤部材２３への動力伝達が、押圧部３３及び受圧部３４に代えて、連結ピン４２によって行われている点である。また、専用キー１４を用いずに、線材等によって第１鉤部材２１に対し解錠操作を行った場合の各部の動きも第１実施形態と同様である。図６（ａ）に示すように、第１鉤部材２１に直接力を加えて下方へ傾動させて第１受け金具６から外しても、第１連結杆２５が第１コイルばね３１に抗して上方へ移動するものの、係合ピン３８が長孔３７で移動するだけで、第２連結杆２６は動かない。第２鉤部材２３は第２受け金具７に係止し続け、前枠３は閉じたままである。
【００３５】
専用キー１４を用いずに、線材等を用い、パチンコ遊技機１の上方から図６（ｂ）に示すように、第２コイルばね３６に抗して第２鉤部材２３に直接力を加えて下方へ傾動させると、同鉤部材２３が第２受け金具７から外れる。第２鉤部材２３の傾動は連結ピン４２によって第２連結杆２６に伝達され、同連結杆２６が引上げられる。この際、回転伝達部３２はカム板１９の第１突起１７から上方へ離れるのみなので、シリンダ錠１５に悪影響を及ぼすおそれはない。第２連結杆２６の動きは、第１伝達経路断続部Ｄの作用により第１連結杆２５に伝達される。詳しくは、第２連結杆２６の動きは長孔３７の下端に位置する係合ピン３８を通じて第１連結杆２５に伝達される。第１連結杆２５は、第２連結杆２６と一体となって、第１コイルばね３１の引張り力に抗して上方（解錠方向）へ移動する。この移動は連結ピン２９を通じて第１鉤部材２１に伝達され、同鉤部材２１が下方へ傾動し第１受け金具６から外れる。このように、第２鉤部材２３の動作は、第１伝達経路断続部Ｄを含む鉤部材解錠伝達機構Ｆの作用により、解錠操作されていない第１鉤部材２１にも伝達され、その鉤部材２１が第１受け金具６から外れ、前枠３が開放可能となる。
【００３６】
このようにすると、第１鉤部材が前枠の下部に位置し、第２鉤部材が上部に位置する一般的なパチンコ遊技機において、不正な解錠操作が第１鉤部材に対して行われ、かつ、パチンコ遊技機の検査等に際し解錠操作が第２鉤部材に対して行われる場合に効果がある。特定の鉤部材（第１鉤部材）に対してのみ不正な解錠操作が行われるのは次の理由による。第１鉤部材が、図１に示すパチンコ遊技機１の発射ツマミ４３や発射レバー４４の近傍に位置するため、不正行為者は、パチンコ遊技時とほとんど同じ姿勢をとりながら、線材等によって第１鉤部材を動かすことができる。不正解錠操作が目立たず、パチンコホールの店員等に見つかりにくい。これに対し、第２鉤部材に対して不正な解錠操作をできないわけではないが、パチンコ遊技機及び球貸し機間の隙間上部に線材等を差込んだのでは、通常のパチンコ遊技時とは大きく異なる姿勢をとることになるため、不正行為が目立ち、店員等に見つかりやすい。目立たずに第２鉤部材を解錠操作するには、前記隙間の下部から線材等を差込み、その先端部を上方まで送り、第２鉤部材を引下げることになるが、線材等を操作する箇所が第２鉤部材から大きく離れていることから、線材等の先端部を第２鉤部材に引っ掛かるように位置合せするのが難しい。このため、第２鉤部材に対する不正な解錠操作が可能とはいえ容易ではなく、結果として、第１鉤部材に対し不正解錠操作が行われることになる。本実施形態の施錠装置８では、前述したように、第１鉤部材２１から第２鉤部材２３への動力伝達が遮断されるので、前記の第１鉤部材２１に対する不正解錠操作が行われても、第２鉤部材２３が第２受け金具７から外れるのを確実かつ効果的に阻止し、前枠３の不正な開放を防止することができる。
【００３７】
また、工場等でのパチンコ遊技機の検査、組付け等に際し行われる作業の１つに、同遊技機を立てた状態で床におき、前枠を閉じたり開いたりする作業がある。このときにいちいち専用キーを用いて解錠するのでは作業性が悪いことから、従来は鉤部材を押し下げることが行われている。押下げの対象となるのは第２鉤部材である。これは、上側に位置する第２鉤部材に対して解錠操作すれば、下側に位置する第１鉤部材に対して行う場合に比べ、作業者が無理な姿勢を取らなくてもすむからである。本実施形態の施錠装置８では、前述したように、第２鉤部材２３から第１鉤部材２１へ動力伝達が行われるので、第２鉤部材２３に対し解錠操作を行うだけで、第１鉤部材２１を第１受け金具６から外し、前枠３を開放することができる。このように、第２実施形態によれば、第１鉤部材２１を動かして解錠する不正解錠を防止しつつ、検査等の際に第２鉤部材２３を動かして容易に解錠することができる。従来の施錠装置が有する、作業に対する利便性を損なうことがない。
【００３８】
なお、本発明は次に示す別の実施形態に具体化することができる。
（１）本発明の施錠装置は、前枠を外枠に開閉可能に支持し、かつ前枠が閉じられたときにその前枠を外枠に係止するようにした遊技機であれば、種類にかかわらず広く適用することができる。このような種類としては、前述したパチンコ遊技機のほかにも例えばパチスロ遊技機が挙げられる。
【００３９】
（２）施錠装置８において、３つ以上の鉤部材を用いてもよいことについては既に説明したが、この場合、第１鉤部材２１及び第２鉤部材２３以外の鉤部材（以下、この項において「他の鉤部材」という）は、専用キー１４の解錠操作に応じたシリンダ錠１５の動作が伝達されて受け金具から外れるものであればよく、第１鉤部材２１に対する解錠操作に応じた同鉤部材２１の動作が伝達されるものであってもよいし、伝達されないものであってもよい。要するに、第１鉤部材２１が不正に動かされたときに、少なくとも１つの鉤部材が動かず、受け金具から外れなければよい。従って、上記の条件を満たす範囲での変更が可能であり、例えば、他の鉤部材は第１連結杆２５に動力伝達可能に連結されてもよいし、第２連結杆２６に動力伝達可能に連結されてもよい。他の鉤部材の連結杆に対する連結構造としては、第１鉤部材の連結構造と同様に連結ピンを用いたものであってもよいし、第２鉤部材の連結構造と同様に押圧部及び受圧部を用いたものであってもよい。
【００４０】
（３）前枠に対する施錠装置の取付け位置は、前記実施形態で説明した箇所（前枠の右側部）に限られず、例えば左側部、上部、下部であってもよい。
【００４１】
以上、本発明の実施形態について説明したが、各実施形態から把握できる請求項以外の技術的思想について、それらの効果とともに記載する。
【００４２】
（イ）請求項１に記載の遊技機の施錠装置において、前記第１鉤部材が前記前枠の下部に設けられていることを特徴とする遊技機の施錠装置。
【００４３】
不正解錠操作の対象となる施錠装置の鉤部材は、多くの場合、下側に位置するものである。パチンコ遊技機をはじめとする一般的な遊技機の下部には、弾球等の発射ツマミや発射レバーがあり、この近くにある鉤部材に対してであれば、目立たずに不正解錠操作ができるからである。（イ）では、このように不正解錠操作が行われやすい箇所に第１鉤部材を配置している。従って、必要最小限の伝達遮断機構だけで効果的に不正解錠を防止することができる。
【００４４】
（ロ）請求項１に記載の遊技機の施錠装置において、
前記第２鉤部材は前記前枠の上部に設けられており、
前記第２鉤部材に対する解錠操作に応じた同第２鉤部材の動作を、解錠操作されていない全ての鉤部材に伝達する鉤部材解錠伝達機構をさらに備えることを特徴とする遊技機の施錠装置。
【００４５】
上記施錠装置において、鍵を用いずに、線材等によって第２鉤部材に対し解錠操作を行うと、その鉤部材は被係止部から離脱する。この第２鉤部材の動作は、鉤部材解錠伝達機構により、解錠操作されていない全ての鉤部材に伝達され、それらの鉤部材が被係止部から離脱し、前枠の開放が可能となる。ところで、工場等での遊技機の検査、組付け等に際し行われる作業の１つに、同遊技機を立てた状態で床におき、前枠を閉じたり開いたりする作業がある。このときにいちいち鍵を用いて解錠するのでは作業性が悪いことから、従来は鉤部材を直接押し下げることが行われている。押下げの対象となるのは上側に位置する鉤部材である。これは、作業者が無理な姿勢を取らなくてもすむからである。（ロ）では、このように作業のしやすい箇所（前枠上部）に第２鉤部材を配置している。従って、第１鉤部材を動かして解錠する不正解錠を防止しつつ、検査等の際に第２鉤部材を動かすだけで全ての鉤部材を被係止部から離脱させることができ、容易に解錠できる。しかも、楽な姿勢で組付け作業や検査作業を行うことができ、作業性の向上を図ることもできる。
【００４６】
なお、上記施錠装置では、仮に第２鉤部材に対して不正な解錠操作が行われた場合、解錠操作されていない全ての鉤部材が被係止部から離脱する不具合が生ずる。しかし、第２鉤部材に対する不正解錠操作のために、遊技機及び球貸し機間の隙間上部に線材等を差込んだのでは、通常の遊技時とは大きく異なる姿勢をとることになるため、不正行為が目立ってしまう。目立たずに第２鉤部材を解錠操作するには、前記隙間の下部から線材等を差込み、その先端部を上方まで送り、第２鉤部材を引下げることになるが、線材等の先端部を第２鉤部材に引っ掛かるように位置合せするのが難しい。このため、第２鉤部材に対する不正な解錠操作が可能とはいえ容易ではない。このような解錠操作は実際には行われず、上記の不具合発生のおそれはないものと考えられる。
【００４７】
（ハ）請求項１に記載の遊技機の施錠装置において、
前記各鉤部材はそれぞれ軸により傾動可能に支持され、その傾動により前記被係止部に対し係止及び離脱するものであり、
前記鍵解錠伝達機構及び前記第１伝達遮断機構は、少なくとも前記第１鉤部材に動力伝達可能に連結された第１連結杆と、少なくとも前記第２鉤部材に動力伝達可能に連結され、かつ前記鍵の解錠操作にともない解錠方向へ移動する第２連結杆と、前記第２連結杆から前記第１連結杆への動力伝達を許容し、第１連結杆から第２連結杆への動力伝達を遮断する第１伝達経路断続部とを備えることを特徴とする遊技機の施錠装置。
【００４８】
上記施錠装置において、鍵を解錠操作すると、第２連結杆が解錠方向へ移動し、その動きが第１伝達経路断続部により第１連結杆に伝達され、同第１連結杆が解錠方向へ移動する。両連結杆の動きは全ての鉤部材に伝達され、同鉤部材が傾動して被係止部から離脱する。一方、鍵を用いずに、線材等によって第１鉤部材に対し不正な解錠操作を行うと、第１鉤部材は被係止部から離脱する。これにともない第１連結杆が移動する。しかし、第１連結杆の動きは、第１伝達経路断続部の作用により第２連結杆へは伝達されず、第２鉤部材が被係止部に係止し続ける。従って、請求項１に記載の発明の効果に加え、少ない部品点数で、かつ簡単な構成で、鍵解錠伝達機構及び第１伝達遮断機構を成立させることができる。
【００４９】
（二）上記（ハ）に記載の遊技機の施錠装置において、
前記第１伝達経路断続部は、前記第１連結杆及び前記第２連結杆の一方に設けられ、連結杆の長さ方向に沿って延びるガイド部と、前記第１連結杆及び第２連結杆の他方に設けられ、前記ガイド部内に往復動可能に係合された係合突部と、前記第１連結杆を反解錠方向へ付勢する第１弾性部材とを備えることを特徴とする遊技機の施錠装置。
【００５０】
上記施錠装置においては、ガイド部内における係合突部の位置に応じて、動力伝達が許容されたり遮断されたりする。詳しくは、第１連結杆に対しては、第１弾性部材による反解錠方向への付勢力が常に作用している。このため、施錠時には係合突部はガイド部内の一方の端部に当っている。この状態から鍵を用いて解錠操作すると、第２連結杆が解錠方向へ移動する。第２連結杆の移動は、ガイド部及び係合突部を介して第１連結杆に伝達する。第１連結杆が第２連結杆と同じ方向へ移動し、全ての鉤部材が傾動して被係止部から離脱する。一方、鍵を用いずに、線材等によって第１鉤部材に対し不正な解錠操作を行うと、第１鉤部材は被係止部から離脱する。これにともない、第１弾性部材の付勢力に抗して第１連結杆が解錠方向へ移動する。しかし、係合突部がガイド部内で移動するのみで、第１連結杆の動きは第２連結杆へは伝達されない。その結果、第２鉤部材は被係止部に係止し続ける。従って、より一層簡単な構成で、上記（ハ）の効果を確実に奏することができる。
【００５１】
（ホ）上記（二）に記載の遊技機の施錠装置において、
前記ガイド部は、前記第１連結杆及び前記第２連結杆の一方にあけられた長孔により構成されていることを特徴とする遊技機の施錠装置。
【００５２】
上記施錠装置においては、鍵を用いた解錠操作時には、係合突部が長孔内の一端に当っており、第２連結杆の動きを第１連結杆に伝達する。線材等を用いた不正解錠操作時には、係合突部が長孔に沿って前記一端から他端へ向けて移動し、第１連結杆の動きを第２連結杆へ伝達しない。従って、上記（二）の効果を奏するほか、第１連結杆又は第２連結杆を加工して孔をあけるだけでガイド部を設けることができる。
【００５３】
（ヘ）請求項１に記載の遊技機の施錠装置において、
前記第２鉤部材に対する解錠操作に応じた同第２鉤部材の動作が、解錠操作されていない鉤部材の少なくとも１つに伝達されるのを遮断する第２伝達遮断機構をさらに備えることを特徴とする遊技機の施錠装置。
【００５４】
上記施錠装置において、鍵を用いずに、線材等によって第２鉤部材に対し不正な解錠操作を行うと、第２鉤部材は被係止部から離脱する。しかし、第２鉤部材の動作は、第２伝達遮断機構の作用により、解錠操作されていない鉤部材の少なくとも１つには伝達されない。その結果、少なくとも１つの鉤部材は被係止部に係止し続ける。従って、第１鉤部材が不正に解錠操作された場合だけでなく、第２鉤部材が不正に解錠操作された場合にも、施錠装置が解錠されるのを防止することができる。
【００５５】
（ト）上記（ヘ）に記載の遊技機の施錠装置において、
前記各鉤部材はそれぞれ軸により傾動可能に支持され、その傾動により前記被係止部に対し係止及び離脱するものであり、
前記鍵解錠伝達機構及び前記第２伝達遮断機構は、第２鉤部材を除く全ての鉤部材に動力伝達可能に連結され、かつ前記鍵の解錠操作にともない解錠方向へ移動する連結杆と、前記連結杆から前記第２鉤部材への動力伝達を許容し、第２鉤部材から連結杆への動力伝達を遮断する第２伝達経路断続部とを備えることを特徴とする遊技機の施錠装置。
【００５６】
上記施錠装置において、鍵を用いて解錠操作すると、連結杆が解錠方向へ移動する。この移動は全ての鉤部材に伝達される。特に、連結杆から第２鉤部材への動力伝達は第２伝達経路断続部によって許容される。その結果、全ての鉤部材が傾動して被係止部から離脱する。一方、鍵を用いずに、線材等によって第２鉤部材に対し不正な解錠操作を行うと、第２鉤部材は被係止部から離脱する。しかし、第２鉤部材から連結杆への動力伝達は第２伝達経路断続部によって遮断されるため、連結杆は動かず、第１鉤部材は被係止部に係止し続ける。従って、上記（ヘ）の効果に加え、少ない部品点数で、かつ簡単な構成で、鍵解錠伝達機構及び第２伝達遮断機構を成立させることができる。
【００５７】
（チ）上記（ト）に記載の遊技機の施錠装置において、
前記第２伝達経路断続部は、前記連結杆に設けられた押圧部と、前記第２鉤部材に設けられ、前記連結杆の解錠方向への移動にともない前記押圧部に当接し、第２鉤部材の解錠操作にともない押圧部から離間する受圧部と、前記受圧部を前記押圧部に当接させる方向へ前記第２鉤部材を付勢する第２弾性部材とを備えることを特徴とする遊技機の施錠装置。
【００５８】
上記施錠装置においては、第２弾性部材によって付勢された第２鉤部材が被係止部に係止している。第２連結杆においては、受圧部が押圧部に当接している。鍵を解錠操作すると、連結杆が解錠方向へ移動する。第２弾性部材の付勢力に抗して第２鉤部材が傾動し、被係止部から離脱する。また、連結杆の動きは第１鉤部材に伝達され、同第１鉤部材が傾動して被係止部から離脱する。一方、鍵を用いずに、線材等によって第２鉤部材に対し不正な解錠操作を行う、すなわち第２弾性部材の付勢力に抗して第２鉤部材を傾動させて、被係止部から離脱させる。このときには、受圧部が押圧部から離間するのみで、第２鉤部材の動きは連結杆に伝達されない。第１鉤部材は被係止部に係止し続ける。従って、より一層簡単な構成で、上記（ト）の効果を確実に奏することができる。
【００５９】
【発明の効果】
以上のように、本発明によれば、線材等により所定の鉤部材に対し不正な解錠操作が行われても、ほかの鉤部材が連動して被係止部から外れるのを阻止することができる。不正な前枠の開放を未然に防止することができる。

BACKGROUND OF THE INVENTION
The present invention is used to lock a front frame to an outer frame when the front frame is closed in a gaming machine such as a pachinko gaming machine or a pachislot machine that supports the front frame so that it can be opened and closed. The present invention relates to a locking device.
[0002]
[Prior art]
Conventionally, a locking device for locking a front frame to an outer frame is incorporated in a gaming machine such as a pachinko gaming machine. As a locking device, a device including a frame, a pair of upper and lower flange members, a connecting rod, a cylinder lock, and a cam plate is well known. The frame is attached to the front frame, and both flange members are supported by shafts at both upper and lower ends of the frame. Each saddle member tilts about a shaft as a fulcrum, and thereby latches and disengages from a receiving metal fitting fixed to the outer frame. The connecting rod is disposed on the frame body so as to be able to reciprocate in the vertical direction, and the upper and lower ends of the connecting rod are connected to the flange member. The cylinder lock is incorporated in the frame, and a key is inserted and unlocked when unlocking. The cam plate is attached to the lock shaft of the cylinder lock, transmits the rotation of the lock shaft accompanying the operation of the key to the connecting rod, and moves the connecting rod downward.
[0003]
According to the locking device described above, at the time of locking, the connecting rod is positioned above and the both flange members are locked to the receiving metal fitting. When the key is rotated in a predetermined direction, the rotation of the lock shaft is transmitted to the connecting rod through the cam plate. Due to the downward movement of the connecting rod, the upper and lower flange members are simultaneously tilted and detached from the metal fittings, respectively, and unlocked. Thus, the locking device is designed to be unlocked when the key is inserted into the cylinder lock and turned.
[0004]
[Problems to be solved by the invention]
By the way, in the pachinko hall sima, a large number of pachinko gaming machines are arranged side by side, and ball lending machines are arranged between adjacent pachinko gaming machines. In order to install this ball lending machine, adjacent pachinko machines are usually arranged at a slightly wider interval than the width of the ball lending machine. Along with this, there is a slight gap between the pachinko gaming machine and the ball lending machine. Therefore, it is possible to insert a wire such as a wire through the gap and apply a force directly to the eaves member, particularly the lower eaves member. When one (lower) collar member is tilted in this way, the movement is also transmitted to the other (upper) collar member via the connecting collar, and the upper and lower collar members are tilted and received together. Detach from the bracket. Originally, there is a problem that a locking device that cannot be unlocked without using a dedicated key is illegally unlocked without using the key.
[0005]
Then, this invention makes it a subject to provide the locking device of the game machine which can prevent the illegal unlocking which moves a collar member illegally with a wire etc. and unlocks it reliably.

[0008]
DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
Hereinafter, a first embodiment in which the present invention is embodied in a locking device for a pachinko gaming machine will be described with reference to the drawings. As shown in FIGS. 1 and 2, the pachinko gaming machine 1 includes an outer frame 2, a front frame (sometimes referred to as an inner frame) 3 that is supported by the shaft 9 so as to be opened and closed, and a front frame. 3 and a glass frame 5 supported by a front frame 3 so as to be opened and closed by a shaft 10.

As shown in FIG. 4B, a lock that is unlocked by a dedicated key (hereinafter referred to as “dedicated key”) 14 for unlocking is attached to the attachment portion 11. Here, the cylinder lock 15 is used as the lock, but other types of locks may be used. In the cylinder lock 15, the dedicated key 14 is inserted and rotated for unlocking, but here, in the clockwise direction when viewed from the front of the pachinko gaming machine 1 (the direction indicated by the arrow in FIG. 4B). ) Is a direction in which the dedicated key 14 is turned when the front frame 3 is opened, and the counterclockwise direction is a direction in which the dedicated key 14 is turned when the glass frame 5 is opened. The cylinder lock 15 is passed through a hole (not shown) formed in the front frame 3. As shown in FIGS. 3A and 3B, the cylinder lock 15 includes a lock shaft 16 that rotates as the dedicated key 14 is operated. A cam plate 19 having a first protrusion 17 and a second protrusion 18 is attached to the lock shaft 16.
[0011]
In the lower part of the support portion 12, a first flange member 21 is supported by a shaft 22 so as to be tiltable in the vertical direction at a position corresponding to the first receiving metal fitting 6. The first collar member 21 is locked to the first metal fitting 6 when being in a substantially horizontal state, and is detached (disengaged) from the metal fitting 6 when tilted downward. Similarly, in the upper part of the support portion 12, the second flange member 23 is supported by a shaft 24 so as to be tiltable in the vertical direction at a position corresponding to the second metal fitting 7. The second flange member 23 is locked to the second metal fitting 7 when it is in a substantially horizontal state, and is detached (disengaged) from the metal fitting 7 when tilted downward. In addition, as the eaves members 21 and 23, a type that detaches from the receiving metal fittings 6 and 7 when tilted upward may be used, or the operation other than the tilting may be performed to engage and release the receiving metal fittings 6 and 7. The type to be used may be used.
[0012]
In the vicinity of the side of the support portion 12 (left side in FIG. 3A), a connecting rod 20 is disposed so as to be capable of reciprocating in the vertical direction. The frame 13 is provided with a mechanism for restricting movement of the connecting rod 20 in the front-rear direction and in the left-right direction. In FIG. 3A, the front-rear direction is indicated by an arrow X, and the left-right direction is indicated by an arrow Y. As a mechanism for regulating the movement in the front-rear direction, a predetermined number of guide pieces 27 are bent at the rear portion of the support portion 12, and the connecting rod 20 is sandwiched between the guide pieces 27 and the attachment portion 11. As a mechanism for restricting the movement in the left-right direction, a predetermined number of restricting projections 28 are formed on the back surface of the mounting portion 11, and the connecting rod 20 is sandwiched between the restricting projections 28 and the support portion 12. These regulation mechanisms are merely examples, and can be changed as appropriate. Of the reciprocating movement of the connecting rod 20 in the vertical direction, the upward movement is related to unlocking. As will be described later, when the connecting rod 20 is moved upward, all the collar members 21 and 23 are detached from the receiving brackets 6 and 7 and unlocked. For this reason, “upward” in the vertical direction that is the reciprocating direction of the connecting rod 20 is referred to as “unlocking direction”.
[0013]
The connecting rod 20 is divided into a first connecting rod 25 and a second connecting rod 26 arranged on the upper side thereof. The first connecting rod 25 has a vertically elongated shape, and is connected to the first flange member 21 at its lower end portion so that power can be transmitted. Here, the lower end portion of the first connecting rod 25 is directly connected to the first flange member 21 by the connecting pin 29. Therefore, both power transmission from the first connecting rod 25 to the first rod member 21 and power transmission in the opposite direction are possible.
[0014]
The second connecting rod 26 has a vertically elongated shape, and a rotation transmitting portion 32 is formed on a part of the second connecting rod 26 so that the first protrusion 17 is brought into contact with the rotation of the cam plate 19. The cam plate 19 and the rotation transmission unit 32 convert the rotational motion of the lock shaft 16 into a linear motion and transmit it to the second connecting rod 26. When the dedicated key 14 is rotated in the clockwise direction to open the front frame 3, the first protrusion 17 comes into contact with the rotation transmitting portion 32 from below and pushes up the second connecting rod 26. In this way, the second connecting rod 26 moves in the unlocking direction as the dedicated key 14 is unlocked. On the contrary, when the dedicated key 14 is turned counterclockwise to open the glass frame 5, the second protrusion 18 pushes down the auxiliary frame 35.
[0015]
The upper end portion of the second connecting rod 26 is connected to the second flange member 23 so that power can be transmitted. However, unlike the lower end part of the 1st connecting rod 25 mentioned above, the upper end part is not connected with the 2nd flange member 23 by the connecting pin. Instead of the connection by the connection pin, a pressing portion 33 is provided at the upper end portion of the second connection rod 26, and a pressure receiving portion 34 is provided at the second flange member 23. Here, the upper end edge of the second connecting rod 26 is used as the pressing portion 33. A part of the second rod member 23 is bent toward the second connecting rod 26, and the bent portion serves as a pressure receiving portion 34. The pressing portion 33 and the pressure receiving portion 34 are merely examples. When the second connecting rod 26 is moved upward (unlocking direction) by the operation of the dedicated key 14, the pressure receiving portion 34 contacts the pressing portion 33, and As long as the condition that the pressure receiving portion 34 is separated from the pressing portion 33 is satisfied when the first collar member 21 is improperly pressed, it can be changed as appropriate. In this change, the pressing portion 33 may be formed integrally with the second connecting rod 26, or may be formed by a separate member and fixed to the second connecting rod 26 by means such as adhesion or welding. The same applies to the pressure receiving unit 34.
[0016]
Further, a second elastic member that urges the second flange member 23 in a direction in which the pressure receiving portion 34 is brought into contact with the pressing portion 33 is used. Here, the second coil spring 36 is used as the second elastic member, and is stretched between the auxiliary frame 35 and the pressure receiving portion 34 in a tensioned state. The second coil spring 36 may be hooked on the frame body 13 instead of the auxiliary frame 35. As the second elastic member, a spring such as a compression coil spring, a torsion coil spring, a leaf spring, or a bar spring may be used, or a material other than the spring, for example, rubber (rubber string or the like) may be used.
[0017]
The 1st connection rod 25 and the 2nd connection rod 26 are connected so that expansion and contraction is possible as follows. One of the connecting rods 25 and 26 is provided with a guide portion extending along the length direction thereof, and the other is provided with an engagement protrusion, and the engagement protrusion is reciprocally inserted into the guide portion. Has been. Here, an elongated hole 37 that is elongated in the vertical direction is formed in the lower end portion of the second connecting rod 26 as a guide portion. An engaging pin 38 is fixed to the upper end of the first connecting rod 25 as an engaging protrusion. The engaging pin 38 is engaged in the long hole 37. Therefore, when the engagement pin 38 is slid in the long hole 37, the connecting rod 20 expands and contracts.
[0018]
Contrary to the above, the guide portion may be provided on the first connecting rod 25 and the engaging protrusion may be provided on the second connecting rod 26. Moreover, as a guide part, not only a long hole but a groove | channel may be sufficient. Furthermore, the 1st elastic member which always urges | biases the 1st connecting rod 25 to the downward direction (anti-unlocking direction) is provided. Here, the first coil spring 31 is used as the first elastic member, and is stretched over the attachment portion 11 and the first connecting rod 25 in a state in which the first coil spring 31 is pulled. As the first elastic member, a spring such as a compression coil spring, a torsion coil spring, a leaf spring, or a bar spring may be used, or a member other than the spring, for example, rubber may be used.
[0019]
And the 1st connection rod 25, the 2nd connection rod 26 which has the rotation transmission part 32, the long hole 37 and the engagement pin 38 which connect both connection rods 25 and 26 so that expansion-contraction is possible, and the 1st connection rod 25 A connecting pin 29 that connects to the first flange member 21, a pressing portion 33 and a pressure receiving portion 34 that connect the second connecting rod 26 to the second flange member 23 so that power can be transmitted, and a first coil spring 31 and a second coil spring. 36 constitutes a key unlock transmission mechanism A, a first transmission blocking mechanism B, and a second transmission blocking mechanism C. These components function as the key unlocking transmission mechanism A, thereby transmitting the operation of the cylinder lock 15 according to the unlocking operation of the dedicated key 14 to all the flange members 21 and 23 and receiving brackets 6 and 7. To be removed. By functioning as the first transmission blocking mechanism B, the movement of the coffin member 21 in response to the unlocking operation on the first coffin member 21 is blocked from being transmitted to the second coffin member 23 that has not been unlocked. To do. By functioning as the second transmission blocking mechanism C, the movement of the coffin member 23 in response to the unlocking operation on the second coffin member 23 is blocked from being transmitted to the first coffin member 21 that has not been unlocked. To do.
[0020]
Among the components of the key unlocking transmission mechanism A and the first transmission blocking mechanism B, the long hole 37, the engagement pin 38 and the first coil spring 31 are the power from the second connection rod 26 to the first connection rod 25. A first transmission path interrupting portion D for allowing transmission and blocking power transmission from the first connecting rod 25 to the second connecting rod 26 is configured. Among the components of the key unlock transmission mechanism A and the second transmission cutoff mechanism C, the pressing portion 33, the pressure receiving portion 34, and the second coil spring 36 allow power transmission from the connecting rod 20 to the second flange member 23, A second transmission path intermittent portion E for interrupting power transmission from the second flange member 23 to the connecting rod 20 is configured.
[0021]
The pachinko gaming machine 1 to which the locking device 8 is assembled is arranged in a horizontal row in the pachinko hall. As shown in FIG. 1, a vertically long ball lending machine 41 is arranged between adjacent pachinko gaming machines 1 as indicated by a two-dot chain line.
[0022]
Next, the operation and effect of the present embodiment configured as described above will be described. FIG. 4A shows a state when the locking device 8 is locked. In this state, the second flange member 23 pulled downward by the second coil spring 36 is engaged with the second metal fitting 7 from below. The upward movement of the second connecting rod 26 is restricted by the pressure receiving portion 34. Further, the first protrusion 17 is in contact with the rotation transmitting portion 32 from below. For this reason, the 2nd connecting rod 26 cannot move up and down. In the first connecting rod 25, the downward pulling force by the first coil spring 31 is always acting, but the engaging pin 38 is in contact with the lower end of the long hole 37, and this contact makes the first connection The downward movement of the collar 25 is restricted. And the 1st collar member 21 connected with the lower end of the 1st coupling rod 25 is latched to the 1st metal fitting 6 from the lower side. The front frame 3 is kept in a closed state by the locking of the two flange members 21 and 23.
[0023]
In order to open the front frame 3, as shown in FIGS. 4B and 4C, when the dedicated key 14 is inserted into the cylinder lock 15 and turned in the direction indicated by the arrow in FIG. And the cam plate 19 rotates in the same direction. As the cam plate 19 rotates, the first protrusion 17 pushes up the second connecting rod 26 through the rotation transmitting portion 32. The movement of the second connecting rod 26 is transmitted to the second flange member 23 by the second transmission path intermittent portion E. Specifically, the movement of the second connecting rod 26 is transmitted to the second flange member 23 through the pressing portion 33 and the pressure receiving portion 34. The second flange member 23 tilts downward against the tensile force of the second coil spring 36 and is detached from the second metal fitting 7. Further, the movement of the second connecting rod 26 is transmitted to the first connecting rod 25 by the first transmission path intermittent portion D. Specifically, the movement of the second connecting rod 26 is transmitted to the first connecting rod 25 through the engaging pin 38 positioned at the lower end of the long hole 37. The first connecting rod 25 is integrated with the second connecting rod 26 and moves upward against the tensile force of the first coil spring 31. This movement is transmitted to the first flange member 21 through the connecting pin 29, and the flange member 21 tilts downward and is detached from the first metal fitting 6. In this way, the cylinder lock 15 operates in response to the unlocking operation of the dedicated key 14, and the operation is performed by the action of the key unlocking transmission mechanism A, the first transmission path intermittent portion D, and the second transmission path intermittent portion E. It is transmitted to all the eaves members 21 and 23. The flange members 21 and 23 are removed from the metal fittings 6 and 7 almost simultaneously, and the front frame 3 can be opened.
[0024]
On the other hand, using the fact that a slight gap is generated between the pachinko gaming machine 1 and the ball lending machine 41, a wire rod such as a wire is inserted through the lower portion of the gap without using the dedicated key 14, and FIG. As shown in a), when a force is directly applied to the first flange member 21 and tilted downward, the first flange member 21 is detached from the first metal fitting 6. However, the operation of the first rod member 21 is not transmitted to the second rod member 23 that has not been unlocked due to the action of the first transmission blocking mechanism B and the first transmission path intermittent portion D. Specifically, the first connecting rod 25 moves upward (unlocking direction) against the first coil spring 31 by the tilting of the first flange member 21. As a result, the engaging pin 38 moves upward from the lower end of the long hole 37. By this movement, power transmission from the first connecting rod 25 to the second connecting rod 26 is interrupted. Although the first connecting rod 25 moves, the second connecting rod 26 does not move, and as a result, the second flange member 23 continues to be locked to the second metal fitting 7. The front frame 3 remains closed.
[0025]
Contrary to the above, a wire rod or the like is inserted through the upper part of the gap between the pachinko gaming machine 1 and the ball lending machine 41 without using the dedicated key 14, and as shown in FIG. If the force is applied directly to the second flange member 23 and tilted downward against the second flange member 23, the same flange member 23 is detached from the second metal fitting 7. However, the operation of the second rod member 23 is not transmitted to the first rod member 21 that has not been unlocked due to the action of the second transmission blocking mechanism C and the second transmission path intermittent portion E. That is, although the second rod member 23 tilts downward, the pressure receiving portion 34 is only separated upward from the pressing portion 33, and the movement of the second rod member 23 is not transmitted to the connecting rod 20. As a result, both the connecting rods 25 and 26 do not move, and the first rod member 21 continues to be locked to the first metal fitting 6. The front frame 3 remains closed.
[0026]
As described above, according to the present embodiment, in the locking device 8 in which all the hook members 21 and 23 are detached from the metal fittings 6 and 7 by unlocking the dedicated key 14, the first hook member 21 is a wire rod or the like. Thus, even if it is moved illegally and removed from the first receiving bracket 6, the second flange member 23 does not come off from the second receiving bracket 7. For this reason, unlike the conventional locking device, unauthorized unlocking can be prevented.
[0027]
By the way, as another measure to prevent unauthorized unlocking, when the unlocking operation is performed using the dedicated key, all the hook members move, and when the other unlocking operations are performed, the hook member does not move. It is possible to do so. For this purpose, for example, a locking member that locks the movement of the connecting rod when locking is completed is supported by the connecting rod, and an unlocking mechanism that unlocks the locking member only when an unlocking operation is performed using a dedicated key is provided. . In this way, during the unlocking operation using the dedicated key, the lock member is unlocked by the action of the lock release mechanism, the connecting rod is moved, and the hook member is tilted to be detached from the receiving metal fitting. However, at the time of an unauthorized unlocking operation that directly tilts the flange member, the connecting rod locked by the lock member does not move, and all the flange members continue to be locked to the receiving metal fittings. Therefore, the same effects as those of the present embodiment can be obtained with respect to preventing unauthorized unlocking.
[0028]
On the other hand, the above measures complicate the structure of the entire locking device including the lock member and the lock mechanism, and increase the number of parts. On the other hand, in this embodiment, the above locking mechanism is not added. In order to cut off the power transmission from the first flange member 21 to the second flange member 23, the connecting rods 25 and 26 are connected to each other by the elongated holes 37 and the engagement pins 38 so as to be extendable and contracted. In order to cut off the power transmission to the first flange member 21, a part of the second connecting rod 26 is used as the pressing portion 33, and the pressure receiving portion 34 is only formed on a part of the second flange member 23. These structures are very simple and have a small number of parts. Therefore, this embodiment is superior to the above measures in terms of assembly workability, maintenance, manufacturing cost, and the like.
[0029]
The present embodiment has the following characteristics in addition to the matters described above.
(A) The key unlocking transmission mechanism A and the first transmission blocking mechanism B can be established with a small and simple configuration of the first coupling rod 25, the second coupling rod 26, and the first transmission path intermittent portion D. . In addition, the first transmission path intermittent portion D can be established with a small and simple configuration of the guide portion, the engaging protrusion, and the first elastic member. Furthermore, the guide portion (the long hole 37) can be provided only by performing a simple process such as punching on the first connecting rod 25 or the second connecting rod 26.
[0030]
(B) A second transmission blocking mechanism C is provided that blocks the movement of the coffin member 23 in response to the unlocking operation on the second coffin member 23 from being transmitted to the first coffin member 21 that has not been unlocked. ing. Therefore, the locking device 8 is prevented from being unlocked not only when the first hook member 21 is illegally unlocked but also when the second hook member 23 is illegally unlocked. be able to. Unauthorized unlocking can be prevented more reliably.
[0031]
(C) The key unlocking transmission mechanism A and the second transmission blocking mechanism C are configured with a small and simple configuration of the coupling rod 20 (the first coupling rod 25, the second coupling rod 26) and the second transmission path interrupting portion E. Can be established. In addition, the second transmission path intermittent portion E can be established with a small and simple configuration of the pressing portion 33, the pressure receiving portion 34, and the second elastic member.
[0032]
(D) The upper end edge of the second connecting rod 26 is used as the pressing portion 33. Further, the pressure receiving portion 34 is formed by bending a part of the second flange member 23. For this reason, it is only necessary to perform a simple process such as a bending process in order to form the pressing part 33 and the pressure receiving part 34.
[0033]
(Second Embodiment)
Next, a second embodiment embodying the present invention will be described with reference to FIGS. The second embodiment is significantly different from the first embodiment in that a hook member unlocking transmission mechanism F is provided instead of the second transmission blocking mechanism C. The heel member unlocking transmission mechanism F is for transmitting the operation of the same heel member 23 according to the unlocking operation on the second heel member 23 to the first heel member 21 which is not unlocked. The first transmission path intermittent portion D described above is included. Specifically, in the first embodiment, the second rod member 23 is connected to the second connecting rod 26 in the same manner as the first rod member 21 is connected to the first connecting rod 25 by the connecting pin 29. The pins 42 are connected. The pressing part 33 and the pressure receiving part 34 are omitted. With the omission of the pressure receiving portion 34, one end (upper end) of the second coil spring 36 is hooked on the upper end portion of the second connecting rod 26. In addition, about the member similar to 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.
[0034]
In this embodiment, the movement of each part when the unlocking operation is performed using the dedicated key 14 is substantially the same as in the first embodiment. The difference from the first embodiment is that power transmission from the second connecting rod 26 to the second flange member 23 is performed by the connecting pin 42 instead of the pressing portion 33 and the pressure receiving portion 34. Further, the movement of each part when the unlocking operation is performed on the first brim member 21 with a wire or the like without using the dedicated key 14 is the same as in the first embodiment. As shown in FIG. 6 (a), even if the first hook member 21 is tilted downward by applying a direct force to the first hook member 21 and removed from the first metal fitting 6, the first connecting hook 25 resists the first coil spring 31. However, only the engagement pin 38 moves through the long hole 37, and the second connecting rod 26 does not move. The second flange member 23 continues to be locked to the second metal fitting 7 and the front frame 3 remains closed.
[0035]
As shown in FIG. 6B from the upper side of the pachinko gaming machine 1 without using the dedicated key 14, a force is directly applied to the second saddle member 23 against the second coil spring 36. When tilted downward, the cogwheel member 23 is detached from the second metal fitting 7. The tilt of the second rod member 23 is transmitted to the second connecting rod 26 by the connecting pin 42, and the connecting rod 26 is pulled up. At this time, since the rotation transmitting portion 32 is only separated upward from the first protrusion 17 of the cam plate 19, there is no possibility of adversely affecting the cylinder lock 15. The movement of the second connecting rod 26 is transmitted to the first connecting rod 25 by the action of the first transmission path intermittent portion D. Specifically, the movement of the second connecting rod 26 is transmitted to the first connecting rod 25 through the engaging pin 38 positioned at the lower end of the long hole 37. The first connecting rod 25 is integrated with the second connecting rod 26 and moves upward (unlocking direction) against the tensile force of the first coil spring 31. This movement is transmitted to the first flange member 21 through the connecting pin 29, and the flange member 21 is tilted downward and detached from the first metal fitting 6. Thus, the operation of the second hook member 23 is also transmitted to the first hook member 21 that has not been unlocked by the action of the hook member unlocking transmission mechanism F including the first transmission path intermittent portion D, The eaves member 21 comes off from the first receiving bracket 6 and the front frame 3 can be opened.
[0036]
In this way, in a general pachinko gaming machine in which the first saddle member is located at the lower part of the front frame and the second saddle member is located at the upper part, an unauthorized unlocking operation is performed on the first saddle member. In addition, this is effective when the unlocking operation is performed on the second saddle member in the inspection of the pachinko gaming machine or the like. The unauthorized unlocking operation is performed only on the specific collar member (first collar member) for the following reason. Since the first saddle member is located in the vicinity of the launching knob 43 and launching lever 44 of the pachinko gaming machine 1 shown in FIG. The heel member can be moved. Unauthorized unlocking operation is inconspicuous and difficult for pachinko hall clerk to find. On the other hand, although it is not impossible to perform an unauthorized unlocking operation on the second hook member, if a wire rod or the like is inserted into the upper part of the gap between the pachinko gaming machine and the ball lending machine, Will take a very different attitude, so cheating is conspicuous and easy to find for shop assistants. In order to unlock the second rod member without conspicuously, the wire rod or the like is inserted from the lower part of the gap, the tip portion is fed upward, and the second rod member is pulled down. Since the location is far away from the second rod member, it is difficult to align the tip of the wire or the like so as to be caught by the second rod member. For this reason, although an unauthorized unlocking operation for the second rod member is possible, it is not easy, and as a result, an unauthorized unlocking operation is performed on the first rod member. In the locking device 8 of the present embodiment, as described above, since the power transmission from the first rod member 21 to the second rod member 23 is interrupted, an unauthorized unlocking operation on the first rod member 21 is performed. However, it is possible to reliably and effectively prevent the second flange member 23 from coming off from the second metal fitting 7 and prevent the front frame 3 from being illegally opened.
[0037]
In addition, one of the operations performed when inspecting and assembling pachinko gaming machines in factories and the like is to place the gaming machine on the floor in a standing state and close or open the front frame. At this time, since the workability is poor if the unlocking is performed using the dedicated key one by one, conventionally, the heel member has been pushed down. The object to be pushed down is the second flange member. This is because if the unlocking operation is performed on the second hook member positioned on the upper side, the operator does not have to take an unreasonable posture as compared with the case of performing the unlocking operation on the first hook member positioned on the lower side. It is. In the locking device 8 of the present embodiment, as described above, power transmission is performed from the second rod member 23 to the first rod member 21, so that only the unlocking operation is performed on the second rod member 23. The eaves member 21 can be removed from the first catch 6 and the front frame 3 can be opened. As described above, according to the second embodiment, the second hook member 23 is moved and unlocked easily at the time of inspection or the like while preventing the unauthorized unlocking that moves and unlocks the first hook member 21. Can do. Convenience for work that the conventional locking device has is not impaired.
[0038]
Note that the present invention can be embodied in another embodiment described below.
(1) The locking device of the present invention is a gaming machine that supports the front frame so that the front frame can be opened and closed, and locks the front frame to the outer frame when the front frame is closed. Can be widely applied regardless of the type. Examples of such types include pachislot machines other than the pachinko gaming machines described above.
[0039]
(2) Although it has already been described that three or more scissors members may be used in the locking device 8, in this case, scissors other than the first scissors member 21 and the second scissors member 23 (hereinafter referred to as this item). The “other scissors member” in FIG. 5 may be any member that can be disengaged from the metal fitting when the operation of the cylinder lock 15 according to the unlocking operation of the dedicated key 14 is transmitted. The corresponding movement of the cogwheel member 21 may be transmitted or may not be transmitted. In short, it is sufficient that at least one hook member does not move and does not come off the receiving metal fitting when the first hook member 21 is moved illegally. Therefore, it is possible to change within a range that satisfies the above conditions. For example, the other flange member may be connected to the first connecting rod 25 so as to be able to transmit power, or to the second connecting rod 26 so as to be able to transmit power. It may be connected. As a connection structure with respect to the connection rod of the other flange member, a connection pin may be used in the same manner as the connection structure of the first flange member, and the pressing portion and the pressure receiving force are similar to the connection structure of the second flange member. A part may be used.
[0040]
(3) The attachment position of the locking device with respect to the front frame is not limited to the location described in the above embodiment (the right side portion of the front frame), and may be, for example, the left side portion, the upper portion, and the lower portion.
[0041]
As mentioned above, although embodiment of this invention was described, it describes with technical effect other than the claim which can be grasped | ascertained from each embodiment with those effects.
[0042]
(A) The gaming machine locking device according to claim 1, wherein the first saddle member is provided at a lower portion of the front frame.
[0043]
In many cases, the hook member of the locking device that is the target of the unauthorized unlocking operation is located on the lower side. At the bottom of general gaming machines such as pachinko machines, there are launching knobs and launching levers such as bullets, and unauthorized unlocking operation is not noticeable if it is against a saddle member nearby Because it can. In (a), the first brim member is arranged in a place where the unauthorized unlocking operation is easily performed. Therefore, unauthorized unlocking can be effectively prevented with only the minimum necessary transmission interruption mechanism.
[0044]
(B) In the gaming machine locking device according to claim 1,
The second flange member is provided on an upper portion of the front frame;
A gaming machine further comprising a hook member unlocking transmission mechanism that transmits the operation of the second hook member according to the unlocking operation to the second hook member to all the hook members that are not unlocked. Locking device.
[0045]
In the above locking device, when the unlocking operation is performed on the second hook member with a wire or the like without using a key, the hook member is detached from the locked portion. The movement of the second hook member is transmitted to all the hook members that have not been unlocked by the hook member unlocking transmission mechanism, and these hook members can be detached from the locked portions and the front frame can be opened. It becomes. By the way, one of the work performed when inspecting and assembling the gaming machine in a factory or the like is to place the gaming machine on the floor in a standing state and close or open the front frame. At this time, unlocking with the key one by one results in poor workability, so conventionally the heel member has been directly pushed down. The object to be pushed down is the eaves member located on the upper side. This is because the worker does not have to take an unreasonable posture. In (b), the second eaves member is arranged in such a place where the work is easy (upper part of the front frame). Therefore, it is possible to remove all the hook members from the locked portion by simply moving the second hook member at the time of inspection or the like, while preventing unauthorized unlocking by moving the first hook member.
