Description

【０００１】
【発明の属する技術分野】
本発明は、開閉部材及びその開閉部材を施錠するための施錠装置を備えた遊技機に関する。
【０００２】
【従来の技術】
一般にパチンコ機等の遊技機では、内部を日常的に保守点検する必要から、遊技機の前面には開閉部材としての前面枠（前面扉ともいう）が開閉可能に設けられ、店員以外の者が無断で前面枠を開放できないようにするために、遊技機には施錠装置が設けられている。かかる施錠装置としては、専用の鍵を用いて操作されるシリンダ錠と、遊技機に設けられた上下一対の被係止部に対しそれぞれ係脱可能に設けられた上側及び下側の鉤部材と、専用鍵によるシリンダ錠の解錠操作に応じて前記上側及び下側鉤部材を作動させる作動機構とを備えたものが知られている。この施錠装置によれば、施錠状態では上下両鉤部材がそれぞれ対応する被係止部に係合することで前面枠が開放不能となる。他方、専用鍵でシリンダ錠を解錠操作することで、作動機構を介して上下両鉤部材が被係止部から同時に離脱し、前面枠が開放可能となる。
【０００３】
【発明が解決しようとする課題】
しかしながら、従来の施錠装置付き遊技機には、遊技機本体と前面枠との間に僅かに生じた隙間から針金等の線材を差し込み、その線材で上側又は下側の鉤部材に直接力を加えて両鉤部材を被係止部から離脱させるという不正行為を受け易いという欠点があった。このため、専用鍵でシリンダ錠を解錠操作せずとも、前面枠の施錠状態が不正に解除され、前面枠が容易に不正開放されてしまうという問題があった。
【０００４】
本発明の目的は、外部から不正な操作を受けても開閉部材の施錠状態を容易に解除することができず、不正行為に対する防御性能（即ち防犯性能）に優れた施錠装置を備えた遊技機を提供することにある。
【０００５】
【課題を解決するための手段】
上記の目的を達成するために、本発明では、遊技機本体と、その前面側に当該遊技機本体に対して開閉される第１開閉部材と、前記遊技機本体又は第１開閉部材に対して開閉される第２開閉部材とを備え、前記各開閉部材の施錠を行う施錠装置を設けた遊技機において、
前記施錠装置は、
基枠と、
その基枠に設けられ、外部操作手段の一方への操作に連動して一方向へ移動し、外部操作手段の他方への操作に連動して他方向へ移動する１つの移動部材と、
前記基枠に設けられ、前記第１開閉部材の施錠位置と解錠位置とに移動可能でありかつ施錠方向へ付勢された少なくとも３つの第１施錠部材と、
前記基枠に設けられ、前記第２開閉部材の施錠位置と解錠位置とに移動可能でありかつ施錠方向へ付勢された複数の第２施錠部材と
を備え、
前記移動部材の前記一方向への移動に連動して前記各第１施錠部材が解錠位置へ移動し、前記移動部材が前記他方向へ移動する場合には前記各第１施錠部材はそれぞれ独立して前記付勢力によって施錠位置に保持されるように構成し、
前記移動部材の前記他方向への移動に連動して前記各第２施錠部材が解錠位置へ移動し、前記移動部材が前記一方向へ移動する場合には前記各第２施錠部材はそれぞれ独立して前記付勢力によって施錠位置に保持されるように構成し、
さらに、前記各開閉部材の少なくとも一方の解錠時に当該解錠される開閉部材を開放方向へ押し出す押し出し手段を前記施錠装置に設けたことを特徴とする。
【０００６】
この場合、前記各開閉部材は一側を開閉中心とし、その他側に前記施錠装置を設け、該他側に沿って延びるように前記移動部材を長尺状に形成し、該移動部材をその長手方向に沿って移動するように構成することが好ましい。
【０００７】
【発明の実施の形態】
はじめに、本実施の形態から抽出され得る発明群を手段ｎ（ｎ＝１，２，３…）として区分して示し、それらを必要に応じて効果等を示しつつ説明する。なお以下においては、理解の容易のため、本実施の形態において対応する構成を括弧書き等で適宜示すが、この括弧書き等で示した具体的構成に限定されるものではない。
【０００８】
手段１．開閉部材及びその開閉部材を施錠する施錠装置を備えた遊技機において、前記施錠装置は、鍵を用いて操作される錠と、遊技機に設けられた被係止部に対し係脱可能に設けることで、それぞれが対応する被係止部に係合する施錠位置と、対応する被係止部から離脱する解錠位置との間を配置切替え可能な少なくとも３つの鉤部材と、前記錠から前記各鉤部材への動作伝達に関与する作動機構であって、前記鍵による錠の解錠操作時には錠の動作を各鉤部材に伝達して前記少なくとも３つの鉤部材を同時に施錠位置から解錠位置に切替えるが、外力によって各鉤部材が個々に施錠位置から解錠位置に切替えられてもその鉤部材の動作を他の鉤部材に伝達しないという一方向的な動作伝達を可能とするように構成された作動機構とを備えることを特徴とする遊技機。
【０００９】
手段１の遊技機によれば、鍵による錠の解錠操作時（即ち正規解錠時）には、一方向的な動作伝達可能に構成された作動機構を介して錠の動作が各鉤部材に伝達され、全ての鉤部材が同時に施錠位置から解錠位置に切替えられる。すると、全ての鉤部材がそれぞれ対応する被係止部から同時に離脱し、開閉部材の施錠が解除されて開閉部材が開放可能となる。これに対し、不正な意図を持った者が例えば線材等を外から遊技機内に挿入し、この線材等を介して鉤部材に直接外力を及ぼして鉤部材を施錠位置から解錠位置に強制切替えするという不正解錠を試みる場合がある。しかし、かかる不正解錠を試みても、前記作動機構は、外力によって各鉤部材が個々に施錠位置から解錠位置に切替えられてもその鉤部材の動作を他の鉤部材に伝達しない構造のため、一つの鉤部材を解錠位置に切替えても他の鉤部材はそれに連動して解錠位置に切替わることはない。つまり、不正解錠を成功させるためには、全ての鉤部材に対して同時に外力を及ぼしこれらを一度に解錠位置に切替える必要がある。ところが、鉤部材は少なくとも３つ（即ち３つ以上）設けられており、人間一人には手が二本しかないため、一人で３つ以上の線材等を操作して３つ以上ある鉤部材に対し同時に外力を及ぼすことはとても無理である。従って、この遊技機によれば、外部から不正な操作を受けても開閉部材の施錠状態を容易に解除することができず、不正行為に対する防御性能（即ち防犯性能）に優れている。
【００１０】
手段２．前記少なくとも３つの鉤部材は、そのうちのいくつかの鉤部材については施錠位置から解錠位置に向けて正方向に配置切替えされることで対応する被係止部から離脱し、残りの鉤部材については施錠位置から解錠位置に向けて前記正方向とは逆向きの逆方向に配置切替えされることで対応する被係止部から離脱するように設けられていることを特徴とする手段１に記載の遊技機。
【００１１】
手段２によれば、３つ以上ある鉤部材は、施錠位置から解錠位置への解錠切替え方向が特定の一方向に揃っておらず、いくつかの鉤部材については解錠切替え方向が正方向に、残りの鉤部材については解錠切替え方向が逆方向にという具合に、解錠切替え方向が正逆入り乱れた状況にある。このため、不正な意図を持った者が３つ以上ある鉤部材について個々に施錠位置から解錠位置に線材等で切替えようとしても、それぞれの鉤部材について適正な解錠切替え方向を把握することは容易でない。少なくとも、個々の鉤部材について適正な解錠切替え方向を把握するまでには相当の試行錯誤が必要で、長い時間と手間がかかるはずである。とすれば、不正な意図を持った者が短時間のうちに当該施錠装置の施錠状態を解除することは極めて困難であり、不正解錠を断念させることもできる。故にこの構成によれば、不正行為に対する防御性能が更に高められる。
【００１２】
手段３．前記少なくとも３つの鉤部材は、そのうちのいくつかの鉤部材については施錠位置と解錠位置との間をスライド可能に設けられると共に、残りの鉤部材については施錠位置と解錠位置との間を支軸を中心として回動可能に設けられており、前記作動機構は、前記少なくとも３つの鉤部材と作動連結されると共に前記スライド可能な鉤部材のスライド方向と同方向にスライド可能な作動部材を具備しており、前記鍵による錠の解錠操作に基づく当該作動部材の正方向スライドに伴い、前記スライド可能な鉤部材が施錠位置から解錠位置に向けて正方向に配置切替えされることで対応する被係止部から離脱すると共に、前記回動可能な鉤部材については施錠位置から解錠位置に向けて前記正方向とは逆向きの逆方向に配置切替えされることで対応する被係止部から離脱することを特徴とする手段１又は２に記載の遊技機。
【００１３】
手段３によれば、いくつかの鉤部材をスライド可能とすると共に残りの鉤部材を支軸を中心として回動可能とし、且つ、作動機構を構成する作動部材を前記スライド可能な鉤部材のスライド方向と同方向にスライド可能とすることにより、鍵による錠の解錠操作に基づく作動部材の正方向スライドに伴って、いくつかの鉤部材が正方向にスライドする一方で、残りの鉤部材が逆方向に回動するというリンク構造が、錠、作動機構（作動部材）及び全ての鉤部材の間に構築される。そして、この構成によれば、３つ以上ある鉤部材は、施錠位置から解錠位置への解錠切替え方向が特定の一方向に揃っておらず、いくつかの鉤部材については解錠切替え方向が正方向に、残りの鉤部材については解錠切替え方向が逆方向にという具合に、解錠切替え方向が正逆入り乱れた状況にある。このため、不正な意図を持った者が３つ以上ある鉤部材について個々に施錠位置から解錠位置に線材等で切替えようとしても、それぞれの鉤部材について適正な解錠切替え方向を把握することは容易でない。少なくとも、個々の鉤部材について適正な解錠切替え方向を把握するまでには相当の試行錯誤が必要で、長い時間と手間がかかるはずである。とすれば、不正な意図を持った者が短時間のうちに当該施錠装置の施錠状態を解除することは極めて困難であり、不正解錠を断念させることもできる。故にこの構成によれば、不正行為に対する防御性能が更に高められる。
【００１４】
手段４．前記回動可能な鉤部材は、その先端部側において被係止部と係合すると共にその基端部側において前記作動部材と作動連結され、前記支軸は当該鉤部材の先端部と基端部との間に設定されていることを特徴とする手段３に記載の遊技機。
【００１５】
手段４によれば、作動部材の正方向スライド時、回動可能な鉤部材の基端部は作動部材に追従して正方向へ変位するが、当該回動可能な鉤部材の先端部は、支軸（回動中心軸）が当該鉤部材の先端部と基端部との間に設定されていることから、基端部の変位方向（正方向）とは逆方向に変位する。この構成によれば、作動部材の正方向スライドに伴う施錠位置から解錠位置への配置切替えが逆方向となる鉤部材を、比較的簡素な機械構造で具体化することができる。
【００１６】
手段５．前記作動部材には、各鉤部材にそれぞれ対応させて少なくとも三つの逃げ溝を形成し、各逃げ溝内には、それぞれ対応する鉤部材に突設されたピン又は係合凸部を係入したことを特徴とする手段３又は４に記載の遊技機。
【００１７】
手段５によれば、作動機構の主要な構成要素である作動部材に少なくとも三つの逃げ溝を形成すると共に、各逃げ溝内に、それぞれ対応する鉤部材に突設されたピン又は係合凸部を係入することにより、前述のような一方向的な動作伝達を可能とする作動機構が比較的簡素な機械構造で具体化される。即ち、前記鍵による錠の解錠操作に基づく作動部材の正方向スライド時には、当該作動部材により錠の動作を各鉤部材に伝達して前記少なくとも３つの鉤部材を同時に施錠位置から解錠位置に切替えるが、外力によって鉤部材が個々に施錠位置から解錠位置に切替えられても、その鉤部材に対応する逃げ溝内をピン又は係合凸部が遊走するだけでその鉤部材の動作を当該作動部材を介して錠及び他の鉤部材に伝達しないという一方向的な動作伝達が実現される。
【００１８】
手段６．前記各鉤部材には、その鉤部材を解錠位置から施錠位置に向けて付勢するための付勢手段が配設されていることを特徴とする手段１〜５のいずれか一項に記載の遊技機。
【００１９】
手段６によれば、３つ以上ある鉤部材の各々が、それぞれ対応する付勢手段によって解錠位置から施錠位置に向けて付勢されている。このため、不正な意図を持った者が線材等を用いて鉤部材を個々に不正解錠しようとする場合でも、各付勢手段の付勢力に抗し得るだけの大きさの外力を各鉤部材に及ぼして施錠位置から解錠位置に切替える必要がある。つまり、開閉部材の不正解錠を成功させるためには、各鉤部材に配設された付勢手段の付勢力に抗して全ての鉤部材を同時に解錠位置に切替える必要がある。遊技機の外からこのように複雑で力のいる不正な操作を加えることは極めて困難である。それ故この構成によれば、不正行為に対する防御性能が飛躍的に高められる。
【００２０】
尚、手段６において、「前記付勢手段がバネであること」は好ましく、「前記付勢手段がコイルバネであること」は更に好ましい。又、手段１〜６において、「前記錠がシリンダ錠であること」は好ましい。
【００２１】
手段７．前記施錠装置は、上側鉤部材、下側鉤部材、並びに、前記上側及び下側鉤部材間に配設された中央鉤部材の三つの鉤部材を備えており、前記上側及び下側鉤部材は、前記作動部材の正方向スライド時に正方向に配置切替えされるスライド可能な鉤部材として構成され、前記中央鉤部材は、前記作動部材の正方向スライド時に逆方向に配置切替えされる回動可能な鉤部材として構成されていることを特徴とする手段３，４，５又は６に記載の遊技機。
【００２２】
手段７によれば、鍵による錠の解錠操作に基づき作動部材が正方向にスライドすることにより、上側及び下側鉤部材が正方向スライドして施錠位置から解錠位置に配置切替えされると共に、中央鉤部材が逆方向回動して施錠位置から解錠位置に配置切替えされる。不正な意図を持った者が開閉部材の不正解錠を達成するためには、線材等を用いて上中下三つの鉤部材に対して外力を及ぼし、これらの三つの鉤部材を同時に正方向スライド及び逆方向回動させて解錠位置に切替える必要があるが、遊技機の外から、このように複雑な不正操作を加えることは極めて困難である。それ故この構成によれば、不正行為に対する防御性能が高められる。
【００２３】
手段８．手段１から手段７のいずれかにおいて、前記遊技機はパチンコ機であること。中でも、パチンコ機の基本構成としては、操作ハンドルを備えており、そのハンドル操作に応じて遊技球を所定の遊技領域に発射させ、遊技球が遊技領域内の所定の位置に配置された作動口に入賞することを必要条件として表示装置における図柄の変動表示が開始すること、又、特別遊技状態発生中には遊技領域内の所定の位置に配置された入賞口が所定の態様で開放されて遊技球を入賞可能として、その入賞個数に応じた有価価値（景品球のみならず、磁気カードへの書込み等も含む）が付与されること等が挙げられる。上記パチンコ機には少なくとも、多数個の遊技球を取得できる遊技者に有利な状態である特別遊技状態（大当り状態）と、遊技球を消費する遊技者に不利な状態である通常遊技状態の二種類の遊技状態が存在する。
【００２４】
手段９．手段１から手段７のいずれかにおいて、前記遊技機はスロットマシンであること。中でも、スロットマシンの基本構成としては、「遊技状態に応じてその遊技状態を識別させるための複数の図柄からなる図柄列を変動表示した後に図柄を確定表示する表示装置を備え、始動用操作手段（例えば操作レバー）の操作に起因して図柄の変動が開始され、停止用操作手段（例えばストップボタン）の操作に起因して或いは所定時間経過することにより図柄の変動が停止され、その停止時の確定図柄が特定図柄であることを必要条件として遊技者に有利な特別遊技状態を発生させる特別遊技状態発生手段とを備えた遊技機」となる。この場合、遊技媒体は、コイン、メダル等が代表例として挙げられる。上記遊技機には少なくとも、多数個の遊技媒体を取得できる遊技者に有利な状態である特別遊技状態（大当り状態）と、遊技媒体を消費する遊技者に不利な状態である通常遊技状態の二種類の遊技状態が存在する。
【００２５】
手段１０．手段１から手段７のいずれかにおいて、前記遊技機はパチンコ機とスロットマシンとを融合させた遊技機であること。中でも、前記融合させた遊技機の基本構成としては、「遊技状態に応じてその遊技状態を識別させるための複数の識別情報からなる図柄列を変動表示した後に図柄を確定表示する表示装置を備え、始動用操作手段（例えば操作レバー）の操作に起因して図柄の変動が開始され、停止用操作手段（例えばストップボタン）の操作に起因して或いは所定時間経過することにより図柄の変動が停止され、その停止時の確定図柄が特定図柄であることを必要条件として遊技者に有利な特別遊技状態を発生させる特別遊技状態発生手段とを備え、遊技媒体として遊技球を使用するとともに、前記識別情報の変動開始に際しては所定数の遊技球を必要とし、特別遊技状態の発生に際しては多くの遊技球が払い出されるよう構成されてなる遊技機」となる。上記遊技機には少なくとも、多数個の遊技球を取得できる遊技者に有利な状態である特別遊技状態（大当り状態）と、遊技球を消費する遊技者に不利な状態である通常遊技状態の二種類の遊技状態が存在する。
【００２６】
以下に、本発明を遊技機としてのパチンコ機に具体化した一実施形態を図面を参照して説明する。図１及び図２に示すようにパチンコ機１０は、外枠１１と、前面枠１２（内枠ともいう）と、ガラス板が嵌め込まれたガラス枠１３と、遊技盤１４とを備えている。遊技盤１４は前面枠１２の内側（裏側）に組み付けられており、前面枠１２と遊技盤１４とが一体化して前面扉を構成している。前面枠１２は外枠１１の左側に設けられた上下一対のヒンジ部１５，１５を介して当該外枠１１に対し回動可能に取り付けられ、外枠１１に対して開閉可能となっている。ガラス枠１３も上下一対の軸支部１６，１６により前面枠１２に対して開閉可能に支持されている。本実施形態では前面枠１２が開閉部材に相当する。
【００２７】
なお、前面枠１２及び遊技盤１４によって構成されるパチンコ機の正面は、その略上半部を占めるガラス枠１３で区画された遊技盤領域と、略下半部を占めると共に前面枠１２に造作された操作領域とに区分される。遊技盤領域には、表示装置、大小様々の入賞口、風車、ランプ、スピーカ、その他の遊技性を高めるための器具や装置（いずれも図示略）が設けられている。他方、操作領域には、弾発のための発射操作ハンドル１７、打球供給皿としての上受け皿１８、余剰玉受皿としての下受け皿１９、その他の器具や装置が設けられている。
【００２８】
前面枠１２の裏面の右側部には、縦長の施錠装置２０が設けられている。この施錠装置２０は、前面枠１２が閉じられたときに前面枠１２を外枠１１に係止して開放不能とするための前面枠用施解錠機構と、ガラス枠１３が閉じられたときにガラス枠１３を前面枠１２に係止して開放不能とするためのガラス枠用施解錠機構とを具備した前面枠及びガラス枠両用の施錠装置である。尚、外枠１１の右側内部には、前面枠１２の施錠に関与する被係止部として、三つの受け金具（上側受け金具１１ａ、下側受け金具１１ｂ及び中央受け金具１１ｃ）が固定されている。同様に前面枠１２及び／又はガラス枠１３には、ガラス枠１３の施錠に関与する被係止部又は被係止機構（図示略）が設けられている。
【００２９】
図３は横倒し状態の施錠装置２０を示し、図４及び図５はその施錠装置２０の上端部近傍を拡大して示す。施錠装置２０は、パチンコ機への取付時に上下方向（図３〜図５では左右方向）に延びる枠体２１を備えている。この枠体２１は、長尺な金属板をほぼ直角に曲げてアングル状（横断面Ｌ字状）に板金加工したものであり、互いに略直交する第１取付け板２２と第２取付け板２３とを有している。この枠体の第１取付け板２２に対しシリンダ錠５０を取付けると共に、第２取付け板２３に対し作動部材３０や三つの鉤部材４１Ａ，４１Ｂ，４１Ｃ等を取り付けることで施錠装置２０が構成されている。
【００３０】
作動部材３０は、枠体２１の長手方向に沿って延びる長尺な板状部材であり、第２取付け板２３に沿ってスライド可能に設けられている。作動部材３０の第２取付け板２３に沿ったスライドは、専用の鍵Ｋによるシリンダ錠５０の解錠操作に基づくものであり、この点については後ほど詳述する。
【００３１】
作動部材３０の両端部付近には、上側受け金具１１ａと係合可能な上側（図３では右側）の鉤部材４１Ａと、下側受け金具１１ｂと係合可能な下側（図３では左側）の鉤部材４１Ｂとが、枠体の第２取付け板２３に沿ってスライド可能に設けられている。上側の鉤部材４１Ａに着目して更に詳しく説明すると、図５に示すように、上側鉤部材４１Ａの一側面にはガイドピン４２が突設され、そのガイドピン４２は第２取付け板２３に形成されたガイド溝２４内に係入している。ガイド溝２４の幅（高さ）はガイドピン４２の軸部の径にほぼ等しいが、ガイドピン４２の頭部は軸部よりも大径化されており、その大径頭部が第２取付け板２３の一側面に接触摺動する構成となっている。このため、上側鉤部材４１Ａは、第２取付け板２３に対し平行状態を保ちながら前記ガイド溝２４の範囲内でスライド可能となっている。
【００３２】
図４及び図５に示すように、上側鉤部材４１Ａの一側面に突設されたフック部４３と、枠体の第１取付け板２２に突設されたフック部２５との間には、付勢手段たるコイルバネ４４が架設されている。このコイルバネ４４は、上側鉤部材４１Ａ及びガイドピン４２を枠体２１の上端に向けて常時付勢するが、ガイドピン４２がガイド溝２４の上端部（図５では右端部）に当接することで上側鉤部材４１Ａのそれ以上の上動が規制される。これにより、上側鉤部材４１Ａが上側受け金具１１ａと係合する施錠位置（図４の実線位置）に位置決めされる。
【００３３】
また、第２取付け板２３と上側鉤部材４１Ａとの間には、作動部材３０の上端部が進入配置されている。その作動部材３０の上端部には、ガイドピン４２の軸部を収容する逃げ溝３１が形成されており、通常時（上側鉤部材４１Ａが施錠位置にあるとき）には、ガイドピン４２は逃げ溝３１の上端部（図５では右端部）に位置する。作動部材３０を図５の待機位置から所定量下動（図５では左移動）させた場合（図６（Ｂ）参照）には、ガイドピン４２と逃げ溝３１の上端部との係合関係に基づき、コイルバネ４４の弾性に抗して作動部材３０と共に上側鉤部材４１Ａが下向きにスライドする。それに伴い、上側鉤部材４１Ａは上側受け金具１１ａから離脱し、施錠位置（図４の実線位置）から解錠位置（図４の仮想線位置）に切替え配置される。その一方で、作動部材３０の長手方向に延びる逃げ溝３１を形成したことにより、施錠位置にある上側鉤部材４１Ａに対し直接外力（例えば針金を用いた不正な押圧力）を加えて上側鉤部材４１Ａを解錠方向に強制スライドさせても、ガイドピン４２がガイド溝２４及び逃げ溝３１内を遊走するばかりであり、又、枠体のガイド溝２４の下端部（図５では左端部）によりそれ以上の下動を規制されて作動部材３０を下動させるには到らない。
【００３４】
作動部材３０を図５の待機位置から所定量上動（図５では右移動）させた場合（図６（Ａ）参照）も、逃げ溝３１の逃し効果により、ガイドピン４２が作動部材３０の上動を阻害することはなく、又、作動部材３０の上動によって上側鉤部材４１Ａと上側受け金具１１ａとの係合関係が解除されることもない。なお、下側鉤部材４１Ｂ及びその周辺の構造も、上側鉤部材４１Ａ及びその周辺とほぼ同様の構造となっている。
【００３５】
図３及び図７に示すように、枠体２１の長手方向中央部には、枠体の第２取付け板２３の一部である平板状の支持部２３ａが突出形成されている。この支持部２３ａには、中央受け金具１１ｃと係合可能な中央鉤部材４１Ｃが支軸２８を介して回動可能に支持されている。支軸２８は、中央鉤部材４１Ｃの先端部（図７では上端部）と基端部（図７では下端部）との間に設定されている。図７（Ａ）及び図８に示すように、中央鉤部材４１Ｃは、その先端部側において中央受け金具１１ｃと係合可能となっている。また、中央鉤部材４１Ｃの基端部の一側面にはガイドピン４５が突設され、そのガイドピン４５は作動部材３０に形成された逃げ溝３６内に係入している。ガイドピン４５の軸部の径は逃げ溝３６の幅（高さ）よりも小さいが、ガイドピン４５の頭部の径は逃げ溝３６の幅よりも大きく設定されている。このガイドピン頭部の存在により、ガイドピン４５が逃げ溝３６内から離脱不能となり、作動部材３０と中央鉤部材４１Ｃとの作動連結が確実となっている。
【００３６】
また、支軸２８の上方において中央鉤部材４１Ｃの一側面に突設されたフック部４６と、枠体の支持部２３ａに突設されたフック部２９との間には、付勢手段たるコイルバネ４７が架設されている。このコイルバネ４７は、中央鉤部材４１Ｃの先端部（図７では上端部）を反時計回りに回動させる方向に中央鉤部材４１Ｃを常時付勢するが、ガイドピン４５が逃げ溝３６の上端部（図７では右端部）に当接することで中央鉤部材４１Ｃのそれ以上の回動が規制される。このコイルバネ４７による付勢作用及びガイドピン４５による回動規制作用により、図７（Ａ）に示すように、中央鉤部材４１Ｃは中央受け金具１１ｃと係合する施錠位置に位置決めされる。尚、コイルバネ４７のバネ力は、中央鉤部材４１Ｃの位置決めに役立つ程度の小さなものであり、コイルバネ４７のバネ力に基づいてガイドピン４５が作動部材３０を強制上動させることはない。
【００３７】
通常時（即ち中央鉤部材４１Ｃが施錠位置にあって中央受け金具１１ｃに係合する施錠時）には、ガイドピン４５は逃げ溝３６の上端部（図７及び図８では右端部）に位置する。作動部材３０を待機位置から所定量下動（図７では左移動）させた場合（図７（Ｂ）参照）には、ガイドピン４５と逃げ溝３６の上端部との係合関係に基づき、コイルバネ４７の弾性に抗して中央鉤部材４１Ｃが時計回りに回動する。それに伴い、中央鉤部材４１Ｃは中央受け金具１１ｃから離脱し、図７（Ａ）の施錠位置から図７（Ｂ）の解錠位置に配置切替えされる。その一方で、作動部材３０の長手方向に延びる逃げ溝３６を形成したことにより、施錠位置にある中央鉤部材４１Ｃに対し直接外力（例えば針金を用いた不正な押圧力）を加えて中央鉤部材４１Ｃを解錠方向（時計方向）に強制回動させても、ガイドピン４５が逃げ溝３６内を遊走するばかりで、ガイドピン４５が逃げ溝３６の下端部を押圧して作動部材３０を解錠に必要なストローク以上に下動させるには到らない。
【００３８】
つまり、図７及び図８に示す中央鉤部材４１Ｃ及びその周辺構造によれば、作動部材３０が下動する場合にはそれに従って中央鉤部材４１Ｃも時計方向に回動するが、中央鉤部材４１Ｃが直接外力によって時計方向に強制回動されても作動部材３０は事実上追従しないという一方的な動作伝達構造が構築される。なお、作動部材３０を待機位置から所定量上動（図７では右移動）させた場合も、逃げ溝３６の逃がし効果により、中央鉤部材４１Ｃ及びそのガイドピン４５が作動部材３０の上動を阻害することはなく、又、作動部材３０の上動によって中央鉤部材４１Ｃと中央受け金具１１ｃとの係合関係が解除されることもない。
【００３９】
上記三つの鉤部材４１Ａ，４１Ｂ及び４１Ｃと作動部材３０との間の作動関係についてまとめると、作動部材３０が待機位置から上動する場合には、三つの鉤部材４１Ａ，４１Ｂ及び４１Ｃは作動部材３０の上動を無条件に許容すると共に作動部材３０の上動に影響されて施錠状態を解除することはない。これに対し、作動部材３０が待機位置から下動する場合には、三つの鉤部材４１Ａ，４１Ｂ及び４１Ｃは作動部材３０の動きに追従して施錠位置から解錠位置にスライド変位又は回動し、それぞれ対応する受け金具１１ａ，１１ｂ及び１１ｃとの係合関係を同時に解除する。即ち、逃げ溝３１，３６を有する作動部材３０や各逃げ溝内に係入されるガイドピン４２，４５等により、シリンダ錠５０から各鉤部材に対して一方向的な動作伝達を可能とする作動機構が構成される。
【００４０】
図３に示すように、枠体２１の略中央部及び下端部並びに作動部材３０の略中央部及び下端部には、ガラス枠１３の施錠又は解錠に関与する一対のガラス枠用係合機構３３，３３が設けられている。各ガラス枠用係合機構３３は、作動部材３０の一側面に突設されたガイドピンを係入するためのガイド溝（兼逃げ溝）が形成された摺動体３３ａと、その摺動体３３ａを下向き方向に付勢するコイルバネ３３ｂとを少なくとも具備している。ガラス枠用係合部としての摺動体３３ａは、前面枠１２及び／又はガラス枠１３に設けられたガラス枠１３を施錠又は解錠するための機構（周知ゆえ説明を省略）と、作動部材３０とを機械的に連動させるための部材であり、作動部材３０の上下動に伴う摺動体３３ａの位置変化に応じて、ガラス枠１３の施錠又は解錠の状態が切り替わる。
【００４１】
また、前記ガラス枠用係合機構３３は、作動部材３０を選択的に付勢するための選択的付勢機構としての働きも兼ねている。即ち、各ガラス枠用係合機構（選択的付勢機構）３３は、作動部材３０が下動する場合には作動部材３０に対し何の影響も及ぼさず作動部材３０の下動を無条件に許容するが、作動部材３０が上動する場合には、作動部材３０を元位置（待機位置）に復帰させる方向（図３の左方向）への付勢作用を及ぼすという働きをする。
【００４２】
なお、専用鍵Ｋでシリンダ錠５０が操作されないとき（通常時）に、作動部材３０が図３及び図５に示す待機位置に安定的に保持されるのは、作動部材３０が、主として上側及び下側鉤部材４１Ａ，４１Ｂ並びに一対のガラス枠用係合機構３３，３３に対し都合４本のガイドピンを介して係合することで、作動部材３０の待機位置が一義的に決定されることによるものである。そして、作動部材３０に外力を及ぼして作動部材３０を待機位置から上動させようとすると、一対のガラス枠用係合機構３３，３３に付属する二つのコイルバネ３３ｂが作動部材３０を元位置（待機位置）に戻そうとする。他方、作動部材３０を待機位置から下動させようとすると、上側及び下側の鉤部材４１Ａ，４１Ｂに割り当てられた二つのコイルバネ４４が作動部材３０を元位置（待機位置）に戻そうとする。
【００４３】
図４及び図５に示すように、枠体２１の上端寄り位置において枠体の第１取付け板２２には、シリンダ錠５０が設けられている。特に図４に示すように、第１取付け板２２には、シリンダ錠用の一対の取付支持部２６，２６が所定間隔を隔てて突設されている。また、シリンダ錠５０の背面側（鍵穴と反対側）には取付フランジ５１が一体化されている。この取付フランジ５１を前記一対の取付支持部２６，２６に載せてからネジ２７で各取付支持部２６に固定することにより、シリンダ錠５０が枠体２１に対して固着されている。
【００４４】
シリンダ錠５０の背面側に突出した錠軸５０ａには、カム５２が一体回動可能に取付けられている。特に図５に示すように、カム５２は、第１腕部５４及び第２腕部５５を有しており、錠軸５０ａを中心とした両腕部５４，５５間の角度は約８０度に設定されている。他方、作動部材３０には、カムの第１腕部５４と係合可能な第１係合溝３４及びカムの第２腕部５５と係合可能な第２係合溝３５が形成されている。専用鍵Ｋによるシリンダ錠５０の操作に応じて、カム５２は、時計方向（図６（Ａ）参照）又は反時計方向（図６（Ｂ）参照）に回動する。カム５２が所定方向に所定量回動すると、第１腕部５４又は第２腕部５５がそれぞれ対応する第１係合溝３４又は第２係合溝３５に進入すると共に、進入した溝の一端部に係合して作動部材３０を特定方向に押し移動させる。
【００４５】
次に、施錠装置２０の作用等について説明する。前面枠１２及びガラス枠１３が完全に閉じられると共にシリンダ錠５０の鍵穴に対して専用鍵Ｋが差し込まれていない施錠状態においては、作動部材３０もカム５２も図５に示す待機位置に配置される。この状態では、３つの鉤部材４１Ａ，４１Ｂ及び４１Ｃがそれぞれ対応する受け金具１１ａ，１１ｂ及び１１ｃと係合して前面枠１２が開放不能になると共に、ガラス枠用係合部としての摺動体３３ａ，３３ａが施錠位置に配置されてガラス枠１３も開放不能となっている。
【００４６】
上記の施錠状態からガラス枠１３を解錠したい場合には、シリンダ錠５０の鍵穴に専用鍵Ｋを差し込み、その専用鍵Ｋをパチンコ機１０の正面（図１参照）から見て左方向（反時計方向）に回動する。すると図６（Ａ）に示すように、カム５２が時計方向に回動して、カムの第２腕部５５が作動部材の第２係合溝３５に進入すると共に第２係合溝３５の上端部（図６では右端部）に当接する。更にカム５２が時計方向に回動されるに従い、第２腕部５５によって作動部材３０が押されながら上方向（図６では右方向）に移動する。図６（Ａ）はカム５２を時計方向に約４０度回動した状態を示す。カム５２を時計方向に約４０度回動することで、作動部材３０が所定距離だけ上動し、それに伴いガラス枠用係合部としての摺動体３３ａ，３３ａも同じ距離だけ上方に変位してガラス枠１３が解錠される。ガラス枠１３が解錠された時点で鍵Ｋを操作する手の力を緩めると、作動部材３０の上動時に蓄力された両選択的付勢機構３３のコイルバネ３３ａのバネ力により、作動部材３０が元位置（待機位置）に強制復帰される。これに伴い、カム５２も待機位置付近にまで復帰回動される。
【００４７】
上記の施錠状態から前面枠１２を解錠したい場合には、シリンダ錠５０の鍵穴に専用鍵Ｋを差し込み、その専用鍵Ｋをパチンコ機１０の正面（図１参照）から見て右方向（時計方向）に回動する。すると図６（Ｂ）に示すように、カム５２が反時計方向に回動して、カムの第１腕部５４が作動部材の第１係合溝３４に進入すると共に第１係合溝３４の下端部（図６では左端部）に当接する。更にカム５２が反時計方向に回動されるに従い、第１腕部５４によって作動部材３０が押されながら下方向（図６では左方向）に移動する。作動部材３０の下動に伴い、逃げ溝３１の端部によってガイドピン４２と一緒に上側鉤部材４１Ａが押し下げられ、同じく下側鉤部材４１Ｂも押し下げられる。その結果、上側及び下側鉤部材４１Ａ，４１Ｂが施錠位置から解錠位置に向けて正方向（図６（Ｂ）では左方向）にスライドする。また図７（Ｂ）に示すように、作動部材３０の下動に伴って、逃げ溝３６の端部によってガイドピン４５と一緒に中央鉤部材４１Ｃの基端部が押し下げられ、その結果、中央鉤部材４１Ｃの先端部が支軸２８を中心として時計方向に回動する。中央鉤部材４１Ｃの先端部の回動方向は、上下両鉤部材４１Ａ，４１Ｂのスライド方向とは逆方向となる。
【００４８】
図６（Ｂ）はカム５２を反時計方向に約４０度回動した状態を示す。カム５２を反時計方向に約４０度回動することで、作動部材３０が所定距離だけ下動し、それに伴い上側及び下側鉤部材４１Ａ，４１Ｂも同じ距離だけ下方（正方向）にスライド変位して、それぞれ対応する受け金具１１ａ，１１ｂとの係合が解除される。また、作動部材３０が所定距離だけ下動することで、中央鉤部材４１Ｃの先端部も所定円弧長だけ時計方向（前記正方向とは逆向きの逆方向）に回動変位して、対応する受け金具１１ｃとの係合が解除される。このように専用鍵Ｋを用いた正規の解錠操作に基づく作動部材３０の下動により、三つの鉤部材４１Ａ，４１Ｂ及び４１Ｃが施錠位置から解錠位置へ同時に切替えられて、前面枠１２が解錠される。尚、前面枠１２が解錠された時点で鍵Ｋを操作する手の力を緩めると、作動部材３０の下動時に蓄力された上側及び下側鉤部材４１Ａ，４１Ｂのコイルバネ４４のバネ力により、作動部材３０が元位置（待機位置）に強制復帰される。これに伴い、カム５２も待機位置付近にまで復帰回動される。
【００４９】
ところで、不正な意図を持った者が、例えば針金等の線材をパチンコ機１０の隙間から内部の施錠装置２０に挿入し、この針金等を介して各鉤部材に直接外力を及ぼして鉤部材を施錠位置から解錠位置に強制的に切替えるという不正解錠を試みる場合がある。しかし、かかる不正解錠を試みても、施錠装置２０の作動機構は、外力によって各鉤部材を個々に施錠位置から解錠位置に切替えても当該鉤部材の動作をシリンダ錠５０及び他の鉤部材に伝達しない構造となっている。具体的には、針金等を用いて、コイルバネ４４のバネ力に抗して上側鉤部材４１Ａ（又は下側鉤部材４１Ｂ）を施錠位置から解錠位置に切替えても、その鉤部材に突設されたガイドピン４２は作動部材３０の逃げ溝３１内を遊走するばかりで当該鉤部材の配置切替えが他の鉤部材（中央鉤部材４１Ｃ等）の配置切替えを誘発することはない。これと同様に、針金等を用いて、コイルバネ４７のバネ力に抗して中央鉤部材４１Ｃを施錠位置から解錠位置に切替えても、その中央鉤部材４１Ｃに突設されたガイドピン４５は作動部材３０の逃げ溝３６内を遊走するばかりで当該中央鉤部材４１Ｃの配置切替えが上側及び下側鉤部材４１Ａ，４１Ｂの配置切替えを誘発することはない。このように、針金等を用いて一つの鉤部材を解錠位置に切替えても、他の鉤部材がそれに連動して解錠位置に切替わることはない。
【００５０】
つまり、不正な意図を持った者が不正解錠を成功させるためには、全３つの鉤部材４１Ａ，４１Ｂ及び４１Ｃに対して同時に外力を及ぼしこれらを一度に解錠位置に切替える必要がある。しかしながら、人間一人には手が二本しかなく、一人で３つの針金等を操作して３つの鉤部材に対し同時に外力を及ぼすことはとても無理であろう。それ故、専用鍵Ｋを用いることなく外部から不正な操作を加えて前面枠１２の解錠を試みることは極めて困難と言える。故に本実施形態のパチンコ機１０は、不正行為に対する防御性能（即ち防犯性能）に優れている。
【００５１】
また、本実施形態では、専用鍵Ｋによるシリンダ錠５０の解錠操作に基づく作動部材３０の正方向スライドに追従して、上側及び下側鉤部材４１Ａ，４１Ｂが解錠位置に向けて正方向にスライドする一方、中央鉤部材４１Ｃが解錠位置に向けて逆方向に回動することにより、前面枠１２が解錠状態となるように構成されている。即ち、上中下三つの鉤部材は、施錠位置から解錠位置への解錠切替え方向が特定の一方向に揃っておらず、上下二つの鉤部材４１Ａ，４１Ｂについては解錠切替え方向が正方向に、中央鉤部材４１Ｃについては解錠切替え方向が逆方向にという具合に、解錠切替え方向が正逆入り乱れた状況にある。このため、不正な意図を持った者が３つの鉤部材について個々に施錠位置から解錠位置に針金等で切替えようとしても、それぞれの鉤部材について適正な解錠切替え方向を把握することは容易ではない。少なくとも、各鉤部材について適正な解錠切替え方向を把握するまでには相当の試行錯誤が必要で、長い時間と手間がかかるはずである。このような理由から、不正な意図を持った者が短時間のうちに当該施錠装置２０の施錠状態を解除することは極めて困難であり、その者に不正解錠を断念させることができる。
【００５２】
更に、本実施形態では、上中下三つの鉤部材４１Ａ，４１Ｂ及び４１Ｃの各々が、それぞれ対応する付勢手段としてのコイルバネ４４，４７によって解錠位置から施錠位置に向けて常時付勢されている。このため、不正な意図を持った者が針金等を用いて鉤部材を個々に不正解錠しようとする場合でも、各コイルバネのバネ力に抗し得るだけの大きさの外力を各鉤部材に及ぼして施錠位置から解錠位置に切替える必要がある。つまり、前面枠１２の不正解錠を成功させるためには各鉤部材に配設されたコイルバネ４４，４７のバネ力に抗して全ての鉤部材４１Ａ，４１Ｂ及び４１Ｃを同時に解錠位置に切替える必要がある。しかし、各コイルバネ４４，４７のバネ力がある程度強ければ、三つの鉤部材に対応する三つのコイルバネのバネ力に抗して当該三つの鉤部材を同時に解錠位置に切替えることは至難の業であり、かかる不正解錠操作は事実上不可能と言ってよい。従って、この構成によれば、不正行為に対する防御性能が飛躍的に高められる。
【００５３】
（変更例）
上記実施形態では、前面枠１２の施錠に関与する鉤部材の数を三つとしたが、鉤部材の数を四つ以上としてもよい。また、本発明をパチンコ機以外の遊技機（例えばスロットマシンや、パチンコ機とスロットマシンとの融合機）に適用してもよい。
【００５４】
【発明の効果】
以上詳述したように本発明の遊技機によれば、外部から不正な操作を受けても開閉部材の施錠状態を容易に解除することができず、不正行為に対する防御性能（即ち防犯性能）を飛躍的に高めることができる。

BACKGROUND OF THE INVENTION
 The present invention relates to an opening / closing member and a gaming machine including a locking device for locking the opening / closing member.
[0002]
[Prior art]
 In general, in gaming machines such as pachinko machines, since the inside needs to be routinely inspected, a front frame (also called a front door) as an opening / closing member is provided on the front of the gaming machine so that it can be opened and closed. In order to prevent the front frame from being opened without permission, the gaming machine is provided with a locking device. Such a locking device includes a cylinder lock that is operated using a dedicated key, and upper and lower hook members that are detachably attached to a pair of upper and lower locked portions provided in the gaming machine, respectively. In addition, there has been known one provided with an operation mechanism for operating the upper and lower hook members in accordance with the unlocking operation of the cylinder lock by a dedicated key. According to this locking device, in the locked state, the upper and lower both-side members engage with the corresponding locked portions, respectively, so that the front frame cannot be opened. On the other hand, when the cylinder lock is unlocked with the dedicated key, the upper and lower arm members are simultaneously detached from the locked portion via the operating mechanism, and the front frame can be opened.
[0003]
[Problems to be solved by the invention]
 However, in a conventional gaming machine with a locking device, a wire such as a wire is inserted through a slight gap formed between the gaming machine main body and the front frame, and a force is directly applied to the upper or lower hook member with the wire. In other words, there is a drawback that it is easy to receive an illegal act of detaching the both flange members from the locked portion. For this reason, even if the cylinder lock is not unlocked with the dedicated key, there is a problem that the locked state of the front frame is illegally released and the front frame is easily opened illegally.
[0004]
 An object of the present invention is to provide a gaming machine equipped with a locking device that cannot easily release the locking state of the opening and closing member even if it receives an unauthorized operation from the outside, and has excellent defense performance against illegal acts (ie, crime prevention performance). Is to provide.
[0005]
[Means for Solving the Problems]
 In order to achieve the above object, in the present invention, a gaming machine main body, a first opening / closing member opened and closed with respect to the gaming machine main body on the front side thereof, and the gaming machine main body or the first opening / closing member A gaming machine comprising a second opening and closing member that is opened and closed, and provided with a locking device that locks each opening and closing member;

And configured to be held in the locked position by the biasing force,
 Further, the locking device is provided with pushing means for pushing the unlocking opening / closing member unlocked when unlocking at least one of the opening / closing members.
[0006]
 In this case, each opening / closing member has an opening / closing center on one side, the locking device is provided on the other side, the moving member is formed in a long shape so as to extend along the other side, and the moving member is formed in the longitudinal direction. It is preferable to be configured to move along the direction.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
 First, invention groups that can be extracted from the present embodiment are shown as means n (n = 1, 2, 3,...), And will be described while showing effects and the like as necessary. In the following, for ease of understanding, the corresponding configuration in the present embodiment is appropriately shown in parentheses, but is not limited to the specific configuration shown in parentheses.
[0008]
 Means 1. In a gaming machine including an opening / closing member and a locking device that locks the opening / closing member, the locking device is detachably provided to a lock operated using a key and a locked portion provided in the gaming machine. Thus, at least three hook members each capable of switching between a locked position that engages a corresponding locked portion and an unlocked position that disengages from the corresponding locked portion, and An operating mechanism that is involved in the transmission of the operation to each heel member, wherein the operation of the lock is transmitted to each heel member during the unlocking operation by the key, and the at least three heel members are simultaneously moved from the locked position to the unlocked position. However, even if each heel member is individually switched from the locked position to the unlocked position by an external force, it is configured to enable one-way motion transmission in which the operation of the heel member is not transmitted to other heel members. An actuated operating mechanism Gaming machine and butterflies.
[0009]
 According to the gaming machine of means 1, during the unlocking operation of the lock with the key (that is, at the time of regular unlocking), the operation of the lock is performed through the operating mechanism configured to transmit the one-way operation. And all the flange members are simultaneously switched from the locked position to the unlocked position. Then, all the eaves members are simultaneously detached from the corresponding locked portions, the locking of the opening and closing members is released, and the opening and closing members can be opened. The On the other hand, a person with an unfair intention inserts a wire rod or the like into the gaming machine from the outside, forcibly switches the rod member from the locked position to the unlocked position by directly applying an external force to the rod member via the wire rod or the like. There are cases where unauthorized unlocking is attempted. However, even when such unauthorized unlocking is attempted, the operating mechanism has a structure that does not transmit the operation of the hook member to other hook members even if each hook member is individually switched from the locked position to the unlocked position by an external force. Therefore, even if one hook member is switched to the unlocking position, the other hook members are not switched to the unlocking position in conjunction with the unlocking position. That is, in order to succeed in the unauthorized unlocking, it is necessary to apply an external force to all the heel members at the same time and switch them to the unlocking position at a time. However, since there are at least three hook members (that is, three or more) and one person has only two hands, one person operates three or more wires and the like to three or more hook members. However, it is impossible to apply external force at the same time. Therefore, according to this gaming machine, the locked state of the opening and closing member cannot be easily released even if an unauthorized operation is received from the outside, and the defense performance against illegal acts (ie, crime prevention performance) is excellent.
[0010]
 Mean 2. The at least three hook members are separated from the corresponding locked portions by switching the forward direction from the locked position to the unlocked position for some of the hook members, and the remaining hook members Is provided so as to be disengaged from the corresponding locked portion by switching the arrangement from the locked position to the unlocked position in the reverse direction opposite to the normal direction. The gaming machine described.
[0011]
 According to the means 2, the unlocking switching direction from the locking position to the unlocking position is not aligned in a specific direction for three or more scissors, and the unlocking switching direction is correct for some of the scissors. In the direction, the unlocking switching direction of the remaining hook members is in the reverse direction, and the unlocking switching direction is in the reverse direction. For this reason, even if there are three or more heel members who have unfair intentions, it is necessary to grasp the appropriate unlocking switching direction for each heel member even if it is attempted to switch from the locked position to the unlocked position with a wire etc. Is not easy. At least it takes a lot of trial and error to grasp the proper unlocking switching direction for each saddle member, and it should take a long time and effort. Then, it is extremely difficult for a person with an unauthorized intention to release the locked state of the locking device in a short time, and the unauthorized unlocking can be abandoned. Therefore, according to this structure, the defense performance with respect to a fraud is further improved.
[0012]
 Means 3. The at least three hook members are slidably provided between a locked position and an unlocked position for some of the hook members, and between the locked position and the unlocked position for the remaining hook members. The actuating mechanism includes an actuating member that is operatively connected to the at least three eaves members and is slidable in the same direction as the sliding direction of the slidable eaves member. As the operating member slides in the forward direction based on the unlocking operation of the lock with the key, the slidable hook member is switched in the forward direction from the locked position toward the unlocked position. It is possible to remove the corresponding locked part and change the arrangement of the pivotable hook member from the locked position to the unlocked position in the reverse direction opposite to the normal direction. The gaming machine according to the means 1 or 2, characterized in that detached from the engaged portion that.
[0013]
 According to the means 3, some of the eaves members can be slid and the remaining eaves members can be rotated around the support shaft, and the operating member constituting the operating mechanism can be slid. By making it slidable in the same direction, several scissors members slide in the positive direction as the actuating member slides in the forward direction based on the unlocking operation of the lock with the key, while the remaining scissors members A link structure that rotates in the reverse direction is constructed between the lock, the operating mechanism (operating member), and all the heel members. And according to this configuration, the unlocking switching direction from the locking position to the unlocking position is not aligned in a specific direction for the three or more scissors, and the unlocking switching direction for some of the scissors Is in the forward direction, the unlocking switching direction is reversed in the reverse direction, and the unlocking switching direction is in the reverse direction. For this reason Even if there are three or more saddle members with a figure to individually switch from the locked position to the unlocked position with a wire or the like, it is not easy to grasp the proper unlocking switching direction for each of the saddle members. At least it takes a lot of trial and error to grasp the proper unlocking switching direction for each saddle member, and it should take a long time and effort. Then, it is extremely difficult for a person with an unauthorized intention to release the locked state of the locking device in a short time, and the unauthorized unlocking can be abandoned. Therefore, according to this structure, the defense performance with respect to a fraud is further improved.
[0014]
 Means 4. The pivotable hook member engages with the locked portion on the distal end side and is operatively connected to the actuating member on the proximal end side, and the support shaft is connected to the distal end portion and the proximal end of the flange member. The gaming machine according to means 3, characterized in that the gaming machine is set between the two parts.
[0015]
 According to the means 4, when the actuating member slides in the forward direction, the base end portion of the rotatable scissors member follows the actuating member and is displaced in the positive direction. Since the support shaft (rotation center axis) is set between the distal end portion and the proximal end portion of the flange member, the shaft is displaced in the direction opposite to the displacement direction (forward direction) of the proximal end portion. According to this configuration, it is possible to embody a saddle member whose arrangement switching from the locked position to the unlocked position accompanying the forward sliding of the actuating member is in the reverse direction with a relatively simple mechanical structure.
[0016]
 Means 5. The actuating member is formed with at least three relief grooves corresponding to the respective flange members, and pins or engaging projections protruding from the corresponding flange members are inserted into the respective relief grooves. The gaming machine according to means 3 or 4, characterized in that.
[0017]
 According to the means 5, at least three relief grooves are formed in the actuating member which is a main component of the actuating mechanism, and pins or engaging projections projecting from the corresponding flange members are formed in the respective relief grooves. As a result, the operating mechanism that enables the one-way motion transmission as described above is realized with a relatively simple mechanical structure. That is, when the actuating member slides in the forward direction based on the unlocking operation of the lock by the key, the actuating member transmits the operation of the lock to each scissor member, and simultaneously moves the at least three scissors members from the locked position to the unlocked position. However, even if the heel member is individually switched from the locked position to the unlocked position by an external force, the operation of the heel member can be controlled only by the pin or the engaging projection moving in the escape groove corresponding to the heel member. One-way motion transmission that does not transmit to the lock and the other heel member via the operating member is realized.

 Means 6. The biasing means for biasing the hook member from the unlocked position toward the locked position is disposed on each of the hook members. Game machines.
[0019]
 According to the means 6, each of the three or more flange members is urged from the unlocked position to the locked position by the corresponding urging means. For this reason, even if a person with an unintentional intention tries to unlock the heel member individually using a wire or the like, an external force large enough to resist the urging force of each urging means is applied to each heel member. It is necessary to change the locking position to the unlocking position on the member. That is, in order to successfully unlock the opening / closing member, it is necessary to simultaneously switch all the heel members to the unlocked position against the urging force of the urging means disposed on each heel member. It is extremely difficult to apply such complicated and powerful illegal operations from outside the gaming machine. Therefore, according to this configuration, the defense performance against fraud is greatly improved.
[0020]
 In the means 6, “the urging means is a spring” is preferable, and “the urging means is a coil spring” is more preferable. In the means 1 to 6, it is preferable that “the lock is a cylinder lock”.

[0022]
 According to the means 7, when the operating member slides in the forward direction based on the unlocking operation of the lock with the key, the upper and lower hook members slide in the forward direction and are switched from the locked position to the unlocked position. The central hook member rotates in the reverse direction and is switched from the locked position to the unlocked position. In order to achieve unauthorized unlocking of the opening / closing member, an unauthorized person exerts an external force on the upper, middle, and lower three flange members using a wire, etc., and simultaneously applies these three flange members to the forward direction. Although it is necessary to switch to the unlocking position by sliding and rotating in the reverse direction, it is extremely difficult to add such a complicated unauthorized operation from outside the gaming machine. Therefore, according to this configuration, the defensive performance against fraud is improved.

On the other hand, the operation area is provided with a firing operation handle 17 for bullets, an upper tray 18 as a hitting ball supply tray, a lower tray 19 as an extra ball tray, and other instruments and devices.
[0028]
 A vertically long locking device 20 is provided on the right side of the back surface of the front frame 12. The locking device 20 includes a front frame locking / unlocking mechanism that locks the front frame 12 to the outer frame 11 when the front frame 12 is closed and cannot be opened, and when the glass frame 13 is closed. This is a locking device for both the front frame and the glass frame, which includes a glass frame locking / unlocking mechanism for locking the glass frame 13 to the front frame 12 so that the glass frame 13 cannot be opened. In addition, inside the right side of the outer frame 11, three receiving metal fittings (upper receiving metal fitting 11a, lower receiving metal fitting 11b, and central receiving metal fitting 11c) are fixed as locked portions involved in locking the front frame 12. Yes. Similarly, the front frame 12 and / or the glass frame 13 is provided with a locked portion or a locked mechanism (not shown) involved in locking the glass frame 13.
[0029]
 FIG. 3 shows the locking device 20 in a lying state, and FIGS. 4 and 5 show the vicinity of the upper end of the locking device 20 in an enlarged manner. The locking device 20 includes a frame body 21 that extends in the vertical direction (left-right direction in FIGS. 3 to 5) when attached to the pachinko machine. The frame body 21 is obtained by bending a long metal plate substantially at a right angle into a sheet metal into an angle shape (L-shaped cross section), and a first mounting plate 22 and a second mounting plate 23 that are substantially orthogonal to each other. have. The cylinder lock 50 is attached to the first attachment plate 22 of the frame body, and the locking device 20 is configured by attaching the actuating member 30 and the three flange members 41A, 41B, 41C to the second attachment plate 23. Yes.
[0030]
 The actuating member 30 is a long plate-like member extending along the longitudinal direction of the frame body 21, and is provided so as to be slidable along the second mounting plate 23. The slide along the second mounting plate 23 of the actuating member 30 is based on the unlocking operation of the cylinder lock 50 with the dedicated key K, which will be described in detail later.
[0031]
 Near both ends of the actuating member 30, there is an upper (right side in FIG. 3) collar member 41A that can be engaged with the upper receiving bracket 11a, and a lower side (left side in FIG. 3) that can be engaged with the lower receiving bracket 11b. The heel member 41B is slidably provided along the second mounting plate 23 of the frame. More specifically, focusing on the upper flange member 41A, as shown in FIG. 5, a guide pin 42 projects from one side surface of the upper flange member 41A, and the guide pin 42 is formed on the second mounting plate 23. The guide groove 24 is engaged. The width (height) of the guide groove 24 is substantially equal to the diameter of the shaft portion of the guide pin 42, but the head portion of the guide pin 42 is larger in diameter than the shaft portion, and the large diameter head portion is the second mounting portion. It is configured to slide in contact with one side of the plate 23. For this reason, the upper flange member 41 A is slidable within the range of the guide groove 24 while maintaining a parallel state with respect to the second mounting plate 23.
[0032]
 As shown in FIGS. 4 and 5, there is a gap between the hook portion 43 protruding from one side of the upper flange member 41A and the hook portion 25 protruding from the first mounting plate 22 of the frame. A coil spring 44 as a biasing means is installed. The coil spring 44 constantly urges the upper flange member 41A and the guide pin 42 toward the upper end of the frame body 21, but the guide pin 42 comes into contact with the upper end portion (the right end portion in FIG. 5) of the guide groove 24. Further upward movement of the upper flange member 41A is restricted. As a result, the upper flange member 41A is positioned at the locking position (solid line position in FIG. 4) where the upper hook member 11a engages.
[0033]
 Further, the upper end portion of the operating member 30 is disposed between the second mounting plate 23 and the upper flange member 41A. A relief groove 31 that accommodates the shaft portion of the guide pin 42 is formed at the upper end portion of the operating member 30, and the guide pin 42 escapes normally (when the upper flange member 41 A is in the locking position). It is located at the upper end (right end in FIG. 5) of the groove 31. When the actuating member 30 is moved downward by a predetermined amount from the standby position in FIG. 5 (leftward in FIG. 5) (see FIG. 6B), the engagement relationship between the guide pin 42 and the upper end of the escape groove 31 is obtained. Therefore, the upper flange member 41A slides downward together with the actuating member 30 against the elasticity of the coil spring 44. Accordingly, the upper flange member 41A is detached from the upper receiving metal fitting 11a and switched from the locking position (solid line position in FIG. 4) to the unlocking position (virtual line position in FIG. 4). On the other hand, since the escape groove 31 extending in the longitudinal direction of the operating member 30 is formed, the upper flange member is directly subjected to an external force (for example, an improper pressing force using a wire) to the upper flange member 41A in the locking position. Even if 41A is forcibly slid in the unlocking direction, the guide pin 42 only moves in the guide groove 24 and the escape groove 31, and the lower end portion (the left end portion in FIG. 5) of the guide groove 24 of the frame body. Further downward movement is restricted and the operating member 30 cannot be moved downward.
[0034]
 Even when the actuating member 30 is moved up by a predetermined amount from the standby position shown in FIG. 5 (rightward in FIG. 5) (see FIG. 6A), the guide pin 42 of the actuating member 30 is removed due to the relief effect of the relief groove 31. The upward movement is not hindered, and the engagement relationship between the upper flange member 41A and the upper receiving metal fitting 11a is not released by the upward movement of the operating member 30. The structure of the lower hook member 41B and its surroundings is also substantially the same as that of the upper hook member 41A and its surroundings.
[0035]
 As shown in FIGS. 3 and 7, a flat plate-like support portion 23 a that is a part of the second mounting plate 23 of the frame body is formed to project at the center portion in the longitudinal direction of the frame body 21. A center rod member 41C that can be engaged with the center bracket 11c is rotatably supported by the support portion 23a via a support shaft 28. The support shaft 28 is set between the distal end portion (upper end portion in FIG. 7) and the proximal end portion (lower end portion in FIG. 7) of the center rod member 41C. As shown in FIGS. 7A and 8, the center flange member 41 C can be engaged with the center receiving bracket 11 c on the tip side. Further, a guide pin 45 projects from one side surface of the base end portion of the center rod member 41 C, and the guide pin 45 is engaged in a clearance groove 36 formed in the operating member 30. The diameter of the shaft portion of the guide pin 45 is smaller than the width (height) of the escape groove 36, but the head diameter of the guide pin 45 is set larger than the width of the escape groove 36. Due to the presence of the guide pin head, the guide pin 45 cannot be removed from the escape groove 36, and the operation connection between the operation member 30 and the center rod member 41C is ensured.
[0036]
 In addition, a coil spring serving as an urging means is provided between the hook portion 46 projecting from one side surface of the central rod member 41C and the hook portion 29 projecting from the support portion 23a of the frame body above the support shaft 28. 47 is installed. The coil spring 47 always urges the central hook member 41C in a direction in which the distal end portion (upper end portion in FIG. 7) of the central hook member 41C is rotated counterclockwise, but the guide pin 45 is supported by the upper end portion of the escape groove 36. By further abutting on (the right end portion in FIG. 7), further rotation of the central collar member 41C is restricted. Due to the biasing action by the coil spring 47 and the rotation restricting action by the guide pin 45, as shown in FIG. 7 (A), the central collar member 41C is positioned at the locking position where it engages with the central bracket 11c. The spring force of the coil spring 47 is small enough to help the positioning of the central flange member 41C, and the guide pin 45 does not force the operating member 30 to move upward based on the spring force of the coil spring 47.
[0037]
 In a normal state (that is, when the central collar member 41C is in the locking position and engaged with the central receiving bracket 11c), the guide pin 45 is positioned at the upper end portion (the right end portion in FIGS. 7 and 8) of the escape groove 36. To do. When the actuating member 30 is moved down a predetermined amount from the standby position (leftward in FIG. 7) (see FIG. 7B), based on the engagement relationship between the guide pin 45 and the upper end of the escape groove 36, The center flange member 41C rotates clockwise against the elasticity of the coil spring 47. Along with this, the central collar member 41C is detached from the central bracket 11c, and is switched from the locked position in FIG. 7 (A) to the unlocked position in FIG. 7 (B). On the other hand, by forming the relief groove 36 extending in the longitudinal direction of the actuating member 30, an external force (for example, an improper pressing force using a wire) is directly applied to the central rod member 41 C at the locking position, and the central rod member Even if 41C is forcibly rotated in the unlocking direction (clockwise), the guide pin 45 only moves in the escape groove 36, and the guide pin 45 presses the lower end of the escape groove 36 to release the operating member 30. It cannot be moved down beyond the stroke required for the lock.
[0038]
 That is, according to the central collar member 41C and its peripheral structure shown in FIGS. 7 and 8, when the actuating member 30 moves down, the central collar member 41C also rotates in the clockwise direction accordingly. Even if the actuator is forcibly rotated clockwise by an external force, a one-side motion transmission structure is constructed in which the operating member 30 does not substantially follow. Even when the actuating member 30 is moved upward by a predetermined amount from the standby position (moved to the right in FIG. 7), the center rod member 41C and its guide pin 45 cause the actuating member 30 to move upward due to the relief effect of the relief groove 36. There is no hindrance, and the upward movement of the actuating member 30 does not release the engagement relationship between the central collar member 41C and the central bracket 11c.
[0039]
 Summarizing the operation relationship between the three flange members 41A, 41B and 41C and the operation member 30, when the operation member 30 moves up from the standby position, the three flange members 41A, 41B and 41C are the operation members. The upward movement of 30 is allowed unconditionally, and the locked state is not released due to the upward movement of the operating member 30. On the other hand, when the actuating member 30 moves down from the standby position, the three hook members 41A, 41B and 41C slide or move from the locked position to the unlocked position following the movement of the actuating member 30. Then, the engagement relationship with the corresponding metal fittings 11a, 11b and 11c is simultaneously released. That is, the operation member 30 having the relief grooves 31 and 36, the guide pins 42 and 45 engaged in the relief grooves, and the like enable one-way operation transmission from the cylinder lock 50 to each flange member. An operating mechanism is configured.
[0040]
 As shown in FIG. 3, a pair of glass frame engagement mechanisms involved in locking or unlocking of the glass frame 13 are provided at the substantially center portion and the lower end portion of the frame body 21 and the substantially center portion and the lower end portion of the operating member 30. 33, 33 are provided. Each glass frame engaging mechanism 33 includes a sliding body 33a in which a guide groove (also serving as a relief groove) for engaging a guide pin protruding from one side surface of the operating member 30 is formed, and the sliding body 33a. And at least a coil spring 33b urging in the downward direction. The sliding body 33a as the engaging portion for the glass frame includes a mechanism for locking or unlocking the glass frame 13 provided on the front frame 12 and / or the glass frame 13 (the description is omitted because it is well known), and the operating member 30. And the state of locking or unlocking of the glass frame 13 is switched according to the position change of the sliding body 33a accompanying the vertical movement of the operation member 30.
[0041]
 The glass frame engaging mechanism 33 also serves as a selective urging mechanism for selectively urging the operating member 30. That is, each glass frame engagement mechanism (selective biasing mechanism) 33 has no effect on the operating member 30 when the operating member 30 is moved downward, and unconditionally moves the operating member 30 downward. Although it is allowed, when the operating member 30 moves upward, it acts to urge the operating member 30 in the direction (left direction in FIG. 3) to return the operating member 30 to the original position (standby position).
[0042]
 When the cylinder lock 50 is not operated with the dedicated key K (normal time), the operating member 30 is stably held in the standby position shown in FIGS. The standby position of the actuating member 30 is uniquely determined by engaging the lower flange members 41A and 41B and the pair of glass frame engaging mechanisms 33 and 33 via four guide pins. Is due to. Then, when an external force is applied to the actuating member 30 to move the actuating member 30 upward from the standby position, the two coil springs 33b attached to the pair of glass frame engagement mechanisms 33, 33 move the actuating member 30 to the original position ( Try to return to the standby position. On the other hand, when the operating member 30 is moved downward from the standby position, the two coil springs 44 assigned to the upper and lower flange members 41A and 41B attempt to return the operating member 30 to the original position (standby position). .
[0043]
 As shown in FIGS. 4 and 5, a cylinder lock 50 is provided on the first mounting plate 22 of the frame body at a position near the upper end of the frame body 21. In particular, as shown in FIG. 4, the first mounting plate 22 is provided with a pair of mounting support portions 26, 26 for cylinder locks protruding at a predetermined interval. A mounting flange 51 is integrated on the back side of the cylinder lock 50 (the side opposite to the keyhole). The cylinder lock 50 is fixed to the frame body 21 by placing the mounting flange 51 on the pair of mounting support portions 26 and 26 and then fixing the mounting flange 51 to the mounting support portions 26 with screws 27.
[0044]
 A cam 52 is attached to a lock shaft 50a protruding to the back side of the cylinder lock 50 so as to be integrally rotatable. In particular, as shown in FIG. 5, the cam 52 has a first arm portion 54 and a second arm portion 55, and the angle between the arm portions 54 and 55 around the lock shaft 50a is about 80 degrees. Is set. On the other hand, the operating member 30 is formed with a first engagement groove 34 that can be engaged with the first arm portion 54 of the cam and a second engagement groove 35 that can be engaged with the second arm portion 55 of the cam. . In response to the operation of the cylinder lock 50 by the dedicated key K, the cam 52 rotates clockwise (see FIG. 6A) or counterclockwise (see FIG. 6B). When the cam 52 rotates by a predetermined amount in a predetermined direction, the first arm portion 54 or the second arm portion 55 enters the corresponding first engagement groove 34 or second engagement groove 35, respectively, and one end of the entered groove. The operating member 30 is pushed and moved in a specific direction by engaging with the portion.
[0045]
 Next, the operation of the locking device 20 will be described. In a locked state in which the front frame 12 and the glass frame 13 are completely closed and the dedicated key K is not inserted into the keyhole of the cylinder lock 50, the operating member 30 and the cam 52 are arranged at the standby position shown in FIG. The In this state, the three flange members 41A, 41B, and 41C are engaged with the corresponding receiving brackets 11a, 11b, and 11c, respectively, so that the front frame 12 cannot be opened, and the sliding body 33a as the glass frame engaging portion. 33a are arranged at the locking position, and the glass frame 13 cannot be opened.
[0046]
 When it is desired to unlock the glass frame 13 from the above-mentioned locked state, the special key K is inserted into the keyhole of the cylinder lock 50, and the special key K is viewed from the front (see FIG. 1) of the pachinko machine 10 in the left direction (reverse direction). Rotate clockwise. Then, as shown in FIG. 6A, the cam 52 rotates clockwise, and the second arm portion 55 of the cam enters the second engagement groove 35 of the operating member and the second engagement groove 35 It abuts on the upper end (right end in FIG. 6). Further, as the cam 52 is rotated clockwise, the operating member 30 is pushed by the second arm portion 55 and moves upward (rightward in FIG. 6). FIG. 6A shows a state where the cam 52 is rotated about 40 degrees clockwise. By rotating the cam 52 by about 40 degrees in the clockwise direction, the actuating member 30 is moved upward by a predetermined distance, and the sliding bodies 33a and 33a as the glass frame engaging portions are also displaced upward by the same distance. The glass frame 13 is unlocked. When the force of the hand that operates the key K is loosened when the glass frame 13 is unlocked, the operating member is actuated by the spring force of the coil spring 33a of the selective biasing mechanism 33 accumulated when the operating member 30 moves up. 30 is forcibly returned to the original position (standby position). Along with this, the cam 52 is also rotated back to the vicinity of the standby position.
[0047]
 When it is desired to unlock the front frame 12 from the above-mentioned locked state, the dedicated key K is inserted into the keyhole of the cylinder lock 50, and the dedicated key K is viewed from the front (see FIG. 1) of the pachinko machine 10 in the right direction (clockwise). Direction). Then, as shown in FIG. 6B, the cam 52 rotates counterclockwise, and the first arm portion 54 of the cam enters the first engagement groove 34 of the operating member and the first engagement groove 34. It contacts the lower end portion (the left end portion in FIG. 6). Further, as the cam 52 is rotated counterclockwise, the operating member 30 is pushed by the first arm portion 54 and moves downward (leftward in FIG. 6). As the operating member 30 moves downward, the upper hook member 41A is pushed down together with the guide pin 42 by the end of the escape groove 31, and the lower hook member 41B is also pushed down. As a result, the upper and lower flange members 41A and 41B slide in the forward direction (leftward in FIG. 6B) from the locked position toward the unlocked position. Further, as shown in FIG. 7B, as the operating member 30 moves downward, the proximal end portion of the central flange member 41C is pushed down together with the guide pin 45 by the end portion of the escape groove 36, and as a result, the center portion The distal end portion of the flange member 41 C rotates clockwise about the support shaft 28. The turning direction of the tip of the central collar member 41C is opposite to the sliding direction of the upper and lower collar members 41A, 41B.
[0048]
 FIG. 6B shows a state where the cam 52 is rotated about 40 degrees counterclockwise. By rotating the cam 52 counterclockwise by about 40 degrees, the operating member 30 is moved downward by a predetermined distance, and the upper and lower flange members 41A and 41B are slid downward (positive direction) by the same distance. Then, the engagement with the corresponding metal fittings 11a and 11b is released. Further, when the actuating member 30 is moved downward by a predetermined distance, the distal end portion of the central scissor member 41C is also rotated and displaced clockwise by a predetermined arc length (the reverse direction opposite to the positive direction). The engagement with the catch 11c is released. Thus, by the downward movement of the operating member 30 based on the regular unlocking operation using the dedicated key K, the three flange members 41A, 41B and 41C are simultaneously switched from the locked position to the unlocked position, and the front frame 12 is moved. Unlocked. When the force of the hand operating the key K is loosened when the front frame 12 is unlocked, the spring force of the coil springs 44 of the upper and lower flange members 41A and 41B accumulated during the downward movement of the operation member 30 is obtained. Thus, the operating member 30 is forcibly returned to the original position (standby position). Along with this, the cam 52 is also rotated back to the vicinity of the standby position.
[0049]
 By the way, a person with an unfair intention, for example, inserts a wire such as a wire into the internal locking device 20 from the gap of the pachinko machine 10, and directly applies an external force to each of the flange members via the wire or the like to remove the flange member. There is a case where an unauthorized unlocking of forcibly switching from the locking position to the unlocking position is attempted. However, even if such an unauthorized unlocking is attempted, the operation mechanism of the locking device 20 does not change the operation of the rod member from the locking position to the unlocking position by an external force. The structure does not transmit to the member. Specifically, even if the upper hook member 41A (or the lower hook member 41B) is switched from the locked position to the unlocked position against the spring force of the coil spring 44 by using a wire or the like, it protrudes from the hook member. The guide pin 42 thus moved only moves in the escape groove 31 of the actuating member 30 and the switching of the arrangement of the rod member does not induce the switching of the arrangement of other rod members (the central rod member 41C, etc.). Similarly, even if the central hook member 41C is switched from the locked position to the unlocked position against the spring force of the coil spring 47 using a wire or the like, the guide pin 45 protruding from the central hook member 41C is Just moving in the escape groove 36 of the actuating member 30, the switching of the arrangement of the central rod member 41C does not induce switching of the arrangement of the upper and lower rod members 41A, 41B. Thus, even if one hook member is switched to the unlocking position using a wire or the like, the other hook members are not switched to the unlocking position in conjunction with the unlocking position.
[0050]
 That is, in order for a person with an unauthorized intention to succeed in the unauthorized unlocking, it is necessary to simultaneously apply external force to all three flange members 41A, 41B and 41C and switch them to the unlocked position at once. However, one person has only two hands, and it would be impossible for one person to operate three wires or the like and apply external force to the three saddle members at the same time. Therefore, it can be said that it is extremely difficult to try to unlock the front frame 12 by applying an unauthorized operation from the outside without using the dedicated key K. Therefore, the pachinko machine 10 of this embodiment is excellent in the defense performance (namely, crime prevention performance) with respect to an unauthorized act.
[0051]
 In the present embodiment, the upper and lower flange members 41A, 41B follow the forward sliding of the actuating member 30 based on the unlocking operation of the cylinder lock 50 with the dedicated key K, and the forward direction is directed toward the unlocking position. On the other hand, the front side frame 12 is configured to be in an unlocked state by rotating the central flange member 41C in the reverse direction toward the unlocked position. That is, the upper, middle, and lower three flange members do not have the same unlocking switching direction from the locking position to the unlocking position, and the upper and lower hook members 41A and 41B have the correct unlocking switching direction. In the direction, the unlocking switching direction is reversed and the center switching member 41C is in a state where the unlocking switching direction is reversed. For this reason, even if a person with an unfair intention tries to switch the three hook members individually from the locked position to the unlocked position with a wire or the like, it is easy to grasp the appropriate unlocking switching direction for each hook member. is not. At least considerable trial and error is required to grasp the proper unlocking switching direction for each saddle member, which should take a long time and effort. For this reason, it is extremely difficult for a person with an unauthorized intention to release the locked state of the locking device 20 in a short time, and the person can be given up on unauthorized unlocking.
[0052]
 Further, in the present embodiment, each of the upper, middle, and lower three flange members 41A, 41B, and 41C is constantly urged from the unlocked position to the locked position by coil springs 44 and 47 as corresponding urging means. Yes. For this reason, even if a person with an unfair intention intends to unlock the hook member individually using a wire or the like, an external force large enough to resist the spring force of each coil spring is applied to each hook member. It is necessary to switch from the locked position to the unlocked position. That is, in order to successfully unlock the front frame 12, all the flange members 41A, 41B and 41C are simultaneously switched to the unlocked position against the spring force of the coil springs 44 and 47 disposed on the flange members. There is a need. However, if the spring force of each of the coil springs 44 and 47 is strong to some extent, it is extremely difficult to simultaneously switch the three hook members to the unlocked position against the spring force of the three coil springs corresponding to the three hook members. Yes, it can be said that such an unauthorized unlocking operation is virtually impossible. Therefore, according to this configuration, the defense performance against fraudulent acts is dramatically improved.
[0053]
 (Example of change)
 In the above embodiment, the number of hook members involved in locking the front frame 12 is three, but the number of hook members may be four or more. Further, the present invention may be applied to a gaming machine other than a pachinko machine (for example, a slot machine or a fusion machine of a pachinko machine and a slot machine).
[0054]
【The invention's effect】
 As described above in detail, according to the gaming machine of the present invention, the locked state of the opening / closing member cannot be easily released even when an unauthorized operation is received from the outside, and the defense performance against illegal acts (ie, the crime prevention performance). It can be improved dramatically.
