【発明の属する技術分野】
本発明は、遊技機裏側に位置して各種部品の取付等に供される機能部材に、遊技状態を制御する制御基板を保持する制御基板ケースを着脱可能に取付ける制御基板ケースの取付構造に関するものである。
【０００２】
【従来の技術】
例えば、遊技機の代表例であるパチンコ機の基本的な構成としては、図６または図７に示すように、外枠Ａの開口前面側に対して前枠Ｂが、連結支持手段および施錠手段を利用して着脱および開放可能に組付けられている。そして前枠Ｂに、横開き式のガラス扉Ｄを組付けた窓枠Ｃと、ガラス扉Ｄの下部において窓枠Ｃに対して着脱および開放可能に組付けられる開閉セット板の前側にセットされた上球皿Ｅおよび裏側にセットされた電動式の球送り装置(図示せず)と、下段に位置する下球皿Ｆおよび打球発射装置Ｈと、裏側に位置する機構セット盤Ｇ等が夫々装備される一方、前枠Ｂ裏側の収容枠体の正面内部に所要の遊技領域Ｉを構成した遊技盤Ｊが着脱交換可能にセットされる。なお、前・後および表・裏は、遊技機を遊技者側から見た状態(図６に示す状態)の関係で指称するものとする。
【０００３】
また、前記遊技盤Ｊの遊技領域Ｉには、始動入賞具や入賞装置Ｍの他に、図柄可変表示装置Ｋ等の遊技部品や、装飾ランプＬ等の各種部材が適宜選択配置されている。図７に示すように、前記遊技盤Ｊの裏側には、球寄せカバーまたは集合樋とも呼ばれ、前記始動入賞具等に通入したセーフ球の案内通路が画成されたセーフ球案内部材６１が取着されており、該セーフ球案内部材６１に形成した開口部６１ａ(図８参照)に、前記図柄可変表示装置Ｋの後方側の突出部が挿通される。更に、前記セーフ球案内部材６１の背面側には、裏カバー部材(図示せず)が着脱可能に配設され、前記図柄可変表示装置Ｋの後方を覆蓋保護するようになっている。
【０００４】
前記パチンコ機Ｐ裏側の所要位置には、パチンコ機Ｐ全体を制御するための主制御基板Ｒや、パチンコ機Ｐの各構成部を制御する、払出制御基板、図柄表示制御基板、音声制御基板、ランプ制御基板、発射制御基板等の各種制御基板が夫々配置され、主制御基板Ｒに対して各種制御基板が電気的に接続されている。そして、前記各種制御基板は、損傷や不正行為等を防止するため、所要の制御基板ケースに収容した状態で、遊技機の裏側に位置して各種部品の取付等に供される機能部材に着脱可能に取付けるようになっている。なお、前記機能部材としては、前記パチンコ機裏側に露出する部材またはパチンコ機裏側に配設される部材であり、例えば、前記前枠Ｂや遊技盤Ｊ、機構セット盤Ｇ、セーフ球案内部材６１、裏カバー部材等が挙げられる。
【０００５】
ここで、パチンコ機Ｐに対する制御基板ケースの取付構造につき、機能部材として前記セーフ球案内部材６１に、制御基板を保持した制御基板ケース５１を取付ける場合を例にして説明する。但し、以下の説明においては、左右とはパチンコ機Ｐを裏側から見た状態(図７に示す状態)の関係で指称する。図８に示すように、前記制御基板を収容する前記制御基板ケース５１は、略矩形に形成されている。そして、前記制御基板ケース５１における一方の側端部(左側端部)５１ａに、上下方向に所要間隔離間して一対の平板状の係合突部５２,５２が外方に向かって延出している。また、前記各係合突部５２に軸孔５２ａが夫々穿設されており、各軸孔５２ａは上下に整列している。更に、前記制御基板ケース５１をセーフ球案内部材６１に取付けた際に、該セーフ球案内部材６１と対向する支持面５１ｂには、前記係合突部５２,５２を形成した左側端部５１ａと反対側の側端部(右側端部)近傍に、上下方向に所要間隔離間して立設される一対の支持片５３ｂ,５３ｂと、両支持片５３ｂ,５３ｂの端部を連結する棒状の係止片５３ａとからなる係止部５３が形成され、後述の係止フック６４と係合するようになっている。
【０００６】
次に、前記制御基板ケース５１が取付けられる前記セーフ球案内部材６１について説明する。前記セーフ球案内部材６１は略矩形に形成され、その所要位置に前記図柄可変表示装置Ｋの後方突出部を挿通し得る開口部６１ａが形成されている。そして、前記セーフ球案内部材６１の背面における左下部に、前記制御基板ケース５１を取付けるケース収容部６２が設けられ、該ケース収容部６２の左側には、上下方向に離間する一対の支持片６３,６３が後方に向けて突設されている。なお、前記両支持片６３,６３の離間間隔は、前記制御基板ケース５１に形成された前記係合突部５２,５２の離間間隔と同等に設定される。また、前記各支持片６３の上面には、前記係合突部５２に形成された前記軸孔５２ａに挿通可能な支軸６３ａが夫々立設されている。
【０００７】
そして、前記各支持片６３から右方向に所要間隔離間した位置に形成された段部に、前記制御基板ケース５１の係止部５３と係合可能で弾性変形し得る係止フック６４が、後方に向かって突設されている。
【０００８】
前記制御基板ケース５１の取付けに際しては、前記セーフ球案内部材６１に形成した前記支持片６３,６３の支軸６３ａ,６３ａに、該制御基板ケース５１に形成した係合突部５２,５２の軸孔５２ａ,５２ａを夫々整列・位置決めして、該制御基板ケース５１を下方移動させて挿通することで、制御基板ケース５１はセーフ球案内部材６１に回動可能に係合される。そして、前記制御基板ケース５１を支軸６３ａ,６３ａを支点として前方向に回動させると、制御基板ケース５１の係止部５３が、前記セーフ球案内部材６１の係止フック６４に当接する。この状態で、前記制御基板ケース５１を後方から前方に向かって押圧すると、前記係止フック６４の弾性変形に伴って前記係止部５３が前方移動すると共に、該係止フック６４が元の位置に復帰することで、該係止部５３の係止片５３ａが係止フック６４と係合する。なお、このとき前記制御基板ケース５１の支持面５１ｂは、前記セーフ球案内部材６１の背面(ケース収容部６２)に当接するようになっている。すなわち、前記制御基板ケース５１の前方向への回動が、前記セーフ球案内部材６１のケース収容部６２により規制されると共に、後方向への回動が、前記係止片５３ａと係止フック６４との係合により規制されて、該制御基板ケース５１が所定位置に取付けられる。
【０００９】
また、前記制御基板ケース５１を取外す際には、該制御基板ケース５１の右側端部近傍を把持して後方側に引っ張り、前記係止片５３ａと係止フック６４との係合を解除する。その後、前記制御基板ケース５１を引き上げて、前記セーフ球案内部材６１の各支軸６３ａを、該制御基板ケース５１の軸孔５２ａから抜き外すことで、当該制御基板ケース５１をセーフ球案内部材６１から離脱させることができる。
【００１０】
【発明が解決しようとする課題】
しかし、前述したように、制御基板ケース５１に形成した係合突部５２,５２の軸孔５２ａ,５２ａに、セーフ球案内部材６１に形成した支持片６３,６３の支軸６３ａ,６３ａを回動可能に挿通した後、該制御基板ケース５１を回動させて前記係止部５３をセーフ球案内部材６１の係止フック６４に係合させる取付構造では、制御基板ケース５１を取外す際に、▲１▼制御基板ケース５１を後方に引っ張って、係止部５３と係止フック６４との係合を解除する動作と、▲２▼制御基板ケース５１を引き上げて、支軸６３ａ,６３ａを軸孔５２ａ,５２ａから抜き外す動作、とが必要とされる。すなわち、作業者は一連の動作で制御基板ケース５１を取外すことができないため、取外し作業は煩わしく、作業効率が劣る欠点が指摘される。
【００１１】
また、前記制御基板ケース５１をセーフ球案内部材６１に取付ける場合には、該セーフ球案内部材６１の各支軸６３ａに、該制御基板ケース５１の各軸孔５２ａを位置決めする必要がある。このように、前記制御基板ケース５１をセーフ球案内部材６１に取付ける作業は煩雑なため、作業効率が低下する問題もある。特に、一度に多数のパチンコ機Ｐに制御基板(制御基板ケース５１)を取付け・取外す必要がある場合には、多大な作業時間を要することとなるため、制御基板ケース５１を簡単な動作で取付け・取外し可能な取付構造の提案が強く望まれている。
【００１２】
【発明の目的】
本発明は、前述した従来の技術に内在している前記課題に鑑み、これを好適に解決するべく提案されたものであって、遊技機の各種制御を行なう制御基板を保持した制御基板ケースを、該遊技機の裏側に位置して各種部品の取付等に供される機能部材に、簡単な操作で取付け・取外しできる制御基板ケースの取付構造を提供することを目的とする。
【００１３】
【課題を解決するための手段】
前記課題を克服し、所期の目的を達成するため、本発明に係る遊技機における制御基板ケースの取付構造は、
遊技機(P)の制御基板を保持する制御基板ケース(21,41)を、該遊技機(P)の裏側に位置して各種部品の取付等に供される機能部材(30)の底面に一体形成したケース収容部 (31)に着脱可能に取付ける制御基板ケースの取付構造において、
前記ケース収容部 (31) の側部に立設され、前記機能部材 (30) の底面から後方へ向けて延出する側壁部 (30b) と、
前記側壁部 (30b) におけるケース収容部 (31) 側の側面に臨む前記制御基板ケース(21,41)の一端縁で、該制御基板ケース (21,41) において前記機能部材 (30) の底面に対向する支持面 (21a,41a) と交差する面に設けられ、該側壁部 (30b) におけるケース収容部 (31) 側の側面へ向けて延出する係合突部(22,42)と、
前記制御基板ケース(21,41)における他端縁側の支持面 (21a,41a) に立設され、前記ケース収容部 (31) の底面へ向けて延出する第１係合部(23,43)と、
前記側壁部 (30b) におけるケース収容部 (31) 側の側面に凹設され、前記係合突部(22,42)の挿入を許容して該ケース収容部 (31)に対する前記制御基板ケース(21,41)の取付け位置を規制する位置決め凹部(32)と、
前記位置決め凹部(32)に設けられ、前記ケース収容部 (31)へ前記制御基板ケース(21,41)を取付けた際に該位置決め凹部(32)に挿入した前記係合突部(22,42)と係脱可能に係合して、当該位置決め凹部(32)から該係合突部(22,42)が逸脱するのを規制する規制部(33)と、
前記制御基板ケース (21,41) の支持面 (21a,41a) に対向する前記ケース収容部 (31) の底面における前記位置決め凹部(32)から離間する位置に、前側に向けて凹ませて形成した段部(30c)と、
前記段部 (30c) に後方へ向けて立設されると共に、前記係合突部 (22,42) の位置決め凹部 (32) への挿脱方向に弾性変形可能に形成され、前記ケース収容部 (31)に制御基板ケース(21,41)を取付けた際に、前記第１係合部(23,43)と係脱可能に係合する第２係合部(34)とから構成したことを特徴とする。
【００１４】
また、前記係合突部(22,42)と前記規制部(33)とを係合させた際に、該係合突部(22,42)を挟んで規制部(33)とは反対側に空間(39)が画成されるように、前記位置決め凹部(32)を形成することもできる。
【００１５】
更に、前記第１係合部(23)は、所要間隔離間して立設した一対の支持片 (23a,23a) と、両支持片 (23a,23a) の端部を連結する係止片 (23b) とから形成され、
前記第２係合部 (34) は、その先端部に、位置決め凹部 (32) 側に延出すると共に幅寸法を前記係止片 (23b) の長さ寸法と略同等に設定した爪部 (35) を有し、前記第１係合部 (23) の両支持片 (23a,23a) の間に位置して爪部 (35) が係止片 (23b) と係合される構成であってもよい。
【００１６】
更にまた、前記ケース収容部 (31) における前記制御基板ケース (21,41) の支持面 (21a,41a) に臨む底面に、後側に突出した支持部(31a)が設けられ、前記係合突部(22,42)を位置決め凹部(32)へ挿入した制御基板ケース(21,41)は、前記支持部(31a)を支点として機能部材(30)に向けて倒伏されると共に、前記支持面 (21a,41a) が支持部 (31a) に当接して前方への移動が規制されるよう構成してもよい。
【００１７】
また、前記規制部(33)における前記位置決め凹部(32)の開口側の先端部は、位置決め凹部の開口端より所要長さだけ該位置決め凹部(32)内に退避している。
【００１８】
そして、前記規制部(33)における前記位置決め凹部 (32) の開口側の先端部は、前後方向に沿う断面が円弧状に形成することもできる。
【００１９】
更に、前記規制部(33)と前記位置決め凹部(32)との連接部(36)を、該位置決め凹部(32)の開口側に向かうにつれて該規制部(33)の先端部側に傾斜するよう構成してもよい。
【００２０】
更にまた、前記制御基板ケース(21,41)における係合突部(22,42)の先端部は、前後方向に沿う断面が円弧状に形成することもできる。
【００２１】
【作用】
本発明に係る制御基板ケースの取付構造では、制御基板を保持した制御基板ケースの一端縁から外方に延出する係合突部を、機能部材の側壁部に凹設した位置決め凹部に挿入して該位置決め凹部に設けた規制部と係合させると共に、該制御基板ケースに設けた第１係合部を、該機能部材におけるケース収容部の段部に設けた第２係合部に係合させることで、当該制御基板ケースが機能部材に取付けられる。そして、前記第１係合部と第２係合部との係合を解除すれば、前記係合突部は、単に前記位置決め凹部に挿入された状態となるので、該係合突部を位置決め凹部から引き抜くだけで前記制御基板ケースを取外すことができる。このように、前記第１係合部と第２係合部との係合を解除するだけで、制御基板ケースを取外せるので、効率的に作業を行なうことができる。また、前記制御基板ケースを取付ける場合には、前記係合突部を前記位置決め凹部に挿入して、前記第１係合部と第２係合部とを係合させれば、該係合突部を前記規制部と係合させることができ、煩雑な位置決めを行なうことなく簡単な作業で取付けることが可能である。更に、第１係合部を、機能部材の底面に対向する支持面に、当該底面に向けて延出して設け、第２係合部を、制御基板ケースに対向するように段部に立設することで、制御基板ケースを着脱する際には、両係合部に対しその延在方向に外力が加わるので、両係合部に掛かる負荷が低減されて耐久性の向上を図り得る。
【００２２】
また、前記係合突部と前記規制部とを係合させた際に、該係合突部を挟んで規制部とは反対側に空間が画成されるように、前記位置決め凹部を形成することで、制御基板ケースを着脱する際に、該規制部と位置決め凹部の底面とで係合突部が挟まれることはなく、当該係合突部に無理な負荷が掛かって損傷等するのを防止し得る。更に、第１係合部の係止片を第２係合部の爪部と略同等の大きさに設定したので、該係止片と爪部を係合させた際に、爪部が両支持片の間に位置するから、制御基板ケースがずれることなく、係合突部を容易に位置決め凹部と対応する位置に臨ませることができる。
【００２３】
そして、前記規制部における前記位置決め凹部の開口側の先端部を、該位置決め凹部の開口端より所要長さだけ当該位置決め凹部内に退避させるようにすれば、前記係合突部を前記位置決め凹部に容易に挿入し得るようになると共に、取外しの際に該係合突部を簡単に抜き出すことができるようになる。また、前記規制部における位置決め凹部の開口側の先端部について、前後方向に沿う断面を円弧状に形成することで、前記係合突部の前記位置決め凹部への挿入をスムーズに行なうことができる。更に、前記規制部と前記位置決め凹部との連接部を、該位置決め凹部の開口側に向かうにつれて該規制部の先端部側に傾斜するようにすれば、前記係合突部と規制部との係合および係合の解除を、スムーズに行ない得る。更にまた、前記係合突部の先端部について、前後方向に沿う断面を円弧状に形成することで、該係合突部の端部が前記位置決め凹部の内部に引っ掛かることなく、前記規制部との係脱をスムーズに行なうことができるようになる。
【００２４】
【発明の実施の形態】
次に、本発明に係る制御基板ケースの取付構造につき好適な実施例を挙げて、添付図面を参照しながら、以下詳細に説明する。なお、本実施例では、代表的な遊技機であるパチンコ機の裏側に位置して各種部品の取付等に供されるセーフ球案内部材(機能部材)に、制御基板を保持した制御基板ケースを取付ける場合で説明する。なお、本実施例におけるパチンコ機の構成は前述した従来の技術と基本的に同じであるので、既出の部材と同一部材には同じ符号を付して、詳細な説明は省略する。
【００２５】
図１または図３に示すように、制御基板ケース２１は略矩形の箱状に形成され、その内部に所要の制御基板が保持されている。そして、前記制御基板ケース２１における一端縁(左側端縁)２１ｂには、上下方向に所要間隔離間して一対の平板状の係合突部２２,２２が外方に向かって所要量だけ延出している。なお、前記各係合突部２２の端部は断面円弧状に形成してある。また、前記制御基板ケース２１をセーフ球案内部材３０に取付けた際に該セーフ球案内部材３０と対向する支持面２１ａにおいて、前記左側端縁２１ｂと対向する他方の側端縁(右側端縁)近傍の位置に、第１係合部２３が設けられる。すなわち、前記第１係合部２３は、前記各係合突部２２の延出方向に対して交差方向へ延出するよう形成されている。前記第１係合部２３は、上下方向に所要間隔離間して立設される略三角状を呈する一対の支持片２３ａ,２３ａと、両支持片２３ａ,２３ａの端部を連結する丸棒状の係止片２３ｂとから形成されており、前記セーフ球案内部材３０に設けられる後述の係止フック(第２係合部)３４と係脱可能に係合するようになっている。
【００２６】
図１に示すように、前記セーフ球案内部材３０は略矩形に形成されて、該セーフ球案内部材３０の右側上部位置に、前記遊技盤Ｊの裏側に突出する前記図柄可変表示装置Ｋの後方部を挿通し得る開口部３０ａが所要の大きさで開口している。そして、前記セーフ球案内部材３０の左下部には、前記制御基板ケース２１を着脱可能に取付けるケース収容部３１が一体的に形成されている。なお、前記ケース収容部３１を別に形成し、前記セーフ球案内部材３０に組付けるよう構成してもよい。また、前記ケース収容部３１における後述の位置決め凹部３２,３２に近接する位置または右方に離間する位置に、該ケース収容部３１の底面より所要の高さだけ後側に突出した突部(支持部)３１ａが複数形成されており、ケース収容部３１に制御基板ケース２１を取付けた際に、該制御基板ケース２１の支持面２１ａが突部３１ａの後端面３１ｂに当接して、制御基板ケース２１の前方移動が規制されるようになっている。
【００２７】
また、前記セーフ球案内部材３０(ケース収容部３１)の左側部には、上下方向の全長に亘って側壁部(内壁面)３０ｂが後方に向かって立設されている。更に、この側壁部３０ｂの下部側(ケース収容部３１と対応する位置)において、上下方向に所要間隔離間して一対の位置決め凹部３２,３２が前後方向(制御基板ケース２１の取付け方向)に凹設されている。なお、各位置決め凹部３２は右方向(ケース収容部３１方向)に開口している。また、両位置決め凹部３２,３２の離間寸法は、前記制御基板ケース２１に形成した前記係合突部２２,２２の離間寸法と同等に設定されて、該位置決め凹部３２,３２の夫々に対応する係合突部２２,２２の挿入を許容して、当該ケース収容部３１に対する制御基板ケース２１の取付け位置を規制するよう構成されている。すなわち、前記各位置決め凹部３２に前記各係合突部２２を挿入することで、前記制御基板ケース２１の上下方向の動きを規制している。
【００２８】
更に、図３に示すように、前記各位置決め凹部３２における前記制御基板ケース２１の後方側(取付け方向手前側、図３において上方)には、規制部３３が設けられている。この規制部３３は、前記制御基板ケース２１の前記支持面２１ａが前記突部３１ａに当接した際に、前記位置決め凹部３２に挿入した前記係合突部２２と係脱可能に係合するよう構成される。すなわち、前記制御基板ケース２１を前記ケース収容部３１に取付けた時に、前記各位置決め凹部３２に挿入した前記各係合突部２２が後方側に逸脱するのを規制して、制御基板ケース２１がケース収容部３１から脱離しないようになっている。
【００２９】
前記位置決め凹部３２における前記規制部３３と対向する底面３２ａと、該規制部３３との離間間隔は、前記ケース収容部３１に前記制御基板ケース２１を着脱するに際し、前記係合突部２２が位置決め凹部３２の底面３２ａに干渉しない寸法に設定されている。すなわち、図３(c)に示すように、前記制御基板ケース２１の支持面２１ａが前記突部３１ａの後端面３１ｂに当接して、前記係合突部２２と前記規制部３３とが係合した際に、該係合突部２２を挟んで規制部３３とは反対側に空間３９が画成されるように、前記位置決め凹部３２を形成してあり、該位置決め凹部３２の底面３２ａが該突部３１ａの後端面３１ｂより前方(取付方向奥側)に位置し、係合突部２２と位置決め凹部３２の底面３２ａとは大きく離間するようになっている。
【００３０】
前記規制部３３における前記位置決め凹部３２の開口側の先端部は、断面円弧状に形成されると共に、該位置決め凹部３２の開口端より所要長さだけ当該位置決め凹部３２内に退避して切欠部３７が形成されている。すなわち、右方向に開口する前記位置決め凹部３２は、この切欠部３７を介して後方にも開口するようになっている。また、前記位置決め凹部３２と規制部３３との連接部３６は、該位置決め凹部３２の開口側に向かうにつれて該規制部３３の先端部側に向かって傾斜するよう形成されている。すなわち、前記連接部３６は断面円弧状に凹設されて、前記位置決め凹部３２に挿入した前記係合突部２２が該連接部３６に干渉することなく、前記規制部３３との係脱を円滑に行ない得るよう構成してある。
【００３１】
また、前記位置決め凹部３２が開口する右方向で、該位置決め凹部３２から所要間隔離間する位置において、前記セーフ球案内部材３０の底面(内壁面)を前側に向かって凹ませて段部３０ｃを形成してある。そして、この段部３０ｃには、前記制御基板ケース２１の第１係合部２３と係脱可能に係合し、弾性変形可能な係止フック３４が後側に向かって立設されて、該制御基板ケース２１をケース収容部３１に取付けた際に、当該制御基板ケース２１の支持面２１ａと対向するようになっている。なお、前記位置決め凹部３２と係止フック３４との離間間隔は、前記制御基板ケース２１の横幅寸法と同程度に設定されて、前記規制部３３と前記係合突部２２とが係合すると共に、該係止フック３４と前記第１係合部２３とが係合するようになっている。
【００３２】
また、前記係止フック３４の爪部３５は、前記位置決め凹部３２側に延出していると共に、該爪部３５の位置決め凹部３２を向く面には、その延出端部から後方に向かうにつれて位置決め凹部３２から離間する傾斜面３４ａが形成されている。そして、前記ケース収容部３１に前記制御基板ケース２１を取付けた時に、前記係止フック３４の爪部３５が前記第１係合部２３の係止片２３ｂと係合するよう構成されている。なお、前記係止フック３４における爪部３５の幅寸法は、前記第１係合部２３における係止片２３ｂの長さ寸法と略同等に設定される。

次に、本実施例に係る制御基板ケースの取付構造の作用について説明する。先ず、パチンコ機Ｐの裏側に位置して各種部品の取付けに供されるセーフ球案内部材３０に、制御基板を保持した制御基板ケース２１を取付ける場合について説明する。図３(a)に示すように、前記制御基板ケース２１の支持面２１ａに形成した第１係合部２３が前記ケース収容部３１に対向する状態で、前記セーフ球案内部材３０(ケース収容部３１)の左側部に形成された側壁部３０ｂの下部側に凹設された位置決め凹部３２,３２に、該制御基板ケース２１の左側端縁に形成した前記係合突部２２,２２を夫々斜めに挿入する。このとき、図３(b)に示すように、前記制御基板ケース２１の左側端縁近傍が前記ケース収容部３１に形成した位置決め凹部３２に近接した突部３１ａ,３１ａの後端面３１ｂ,３１ｂの夫々に当接すると共に、該制御基板ケース２１の支持面２１ａに形成した第１係合部２３の係止片２３ｂが、該ケース収容部３１に形成した係止フック３４の傾斜面３４ａに当接する。
【００３４】
この状態で、前記制御基板ケース２１を前方に向かって押圧して前記ケース収容部３１に向けて前記位置決め凹部３２に近接した突部３１ａ,３１ａを支点にして倒伏させると、前記第１係合部２３の係止片２３ｂが前記係止フック３４の傾斜面３４ａを押圧して、該係止フック３４が弾性変形される。そして、前記制御基板ケース２１の支持面２１ａが、前記位置決め凹部３２から離間する突部３１ａの後端面３１ｂに当接するまで倒伏させると、傾斜面３４ａから係止片２３ｂが離脱して係止フック３４は元の位置に復帰し、係止片２３ｂと係止フック３４の爪部３５とが係合する(図３(c)参照)。また、前記カバー収納部３１の位置決め凹部３２に挿入された前記係合突部２２は、該位置決め凹部３２内を取付け方向手前側(後側)に移動し、当該位置決め凹部３２に設けた前記規制部３３と係合する。
【００３５】
すなわち、前記ケース収容部３１に対する前記制御基板ケース２１の取付け状態では、前記制御基板ケース２１は、前記第１係合部２３と係止フック３４との係合、および前記係合突部２２と規制部３３との係合により、後方移動が規制され、また制御基板ケース２１の支持面２１ａとケース収容部３１の突部３１ａとが当接して前方移動が規制され、該制御基板ケース２１はケース収容部３１に安定的に位置決め保持される。なお、前記制御基板ケース２１は前記係止フック３４により右方向の移動が規制されるので、前記位置決め凹部３２から前記係合突部２２が脱離することはない。
【００３６】
このように、前記制御基板ケース２１を前記ケース収容部３１に取付ける際に、従来のように軸と孔とを位置決めする必要がないので、簡単かつ短時間で取付けることが可能である。また、前記制御基板ケース２１の取付けに際して、前記各位置決め凹部３２に前記各係合突部２２を直接挿入する必要はなく、例えば前記側壁部３０ｂにおける位置決め凹部３２が開口する面に係合突部２２を当接させて上下動させると、該係合突部２２が当該位置決め凹部３２と整列した際に自然に挿入されるため、作業効率が向上する。また、前記係合突部２２と前記規制部３３とを係合させた際に、該係合突部２２を挟んで規制部３３とは反対側に空間３９が画成されるように、前記位置決め凹部３２を形成し、該係合突部２２と、該位置決め凹部３２において規制部３３に対向する底面３２ａとが離間するよう構成してあるので、該制御基板ケース２１を取付ける際に、該規制部３３と位置決め凹部３２の底面３２ａとで係合突部２２が挟まれることはなく、当該係合突部２２に無理な負荷が掛かって損傷等するのを防止し得る。
【００３７】
そして、前記位置決め凹部３２への前記係合突部２２の挿入により取付け位置が規制されて、前記制御基板ケース２１が上下方向にズレることはないので、効率的な作業が可能である。更に、前記規制部３３における前記位置決め凹部３２の開口側の先端部は、該位置決め凹部３２の開口端より所要長さだけ当該位置決め凹部３２内に退避して切欠部３７を形成してある。これにより、前記係合突部２２を前記位置決め凹部３２に挿入する際の位置決めを容易にでき、より一層作業の効率化を図り得ると共に、後方から係合突部２２を該位置決め凹部３２に挿入する場合に切欠部３７がガイド部として作用し、挿入を簡単に行なうことが可能である。また、前記規制部３３の先端部を断面円弧状に形成することで、前記切欠部３７に当接した係合突部２２を前記位置決め凹部３２に容易に挿入し得るようになる。更に、前記係合突部２２を断面円弧状に形成してあるので、該係合突部２２と前記位置決め凹部３２の内壁とが引っ掛からないため、前記規制部３３にスムーズに係合させることができる。更にまた、前記規制部３３と前記位置決め凹部３２との連接部３６を、該位置決め凹部３２の開口側に向かうにつれて該規制部３３の先端部側に傾斜させることで、一層前記係合突部２２の係合をスムーズに行ない得ると共に、該係合突部２２が確実に係合されて前記制御基板ケース２１のガタツキ等が防止される。
【００３８】
次に、前記ケース収容部３１に取付けた制御基板ケース２１を取外す場合について説明する。前記ケース収容部３１に取付けられた前記制御基板ケース２１の右側端部近傍を把持して後方側に引っ張ることで、前記第１係合部２３の係止片２３ａと係止フック３４との係合を解除する。このとき、前記制御基板ケース２１は前記ケース収容部３１に形成した前記位置決め凹部３２に近接する突部３１ａ,３１ａを支点にして回動し、該制御基板ケース２１の係合突部２２と前記位置決め凹部３２に設けた規制部３３との係合も解除される(図３(b))。そして、前記制御基板ケース２１をこのまま後方に移動させると、前記係合突部２２が前記位置決め凹部３２から抜き出され、該制御基板ケース２１を取外すことができる(図３(a))。このように、前記第１係合部２３と係止フック３４との係合を解除する操作だけで前記制御基板ケース２１の取外しができるので、作業時間が短縮して作業効率が向上する。
【００３９】
ここで、前記係合突部２２と前記規制部３３とが係合した際に、該係合突部２２を挟んで規制部３３とは反対側に空間３９が画成されるように、前記位置決め凹部３２を形成して、係合突部２２が位置決め凹部３２の底面３２ａに干渉しないよう設定されている。このため、前記ケース収容部３１から前記制御基板ケース２１を後方側に引張って、前記第１係合部２３と係止フック３４との係合が解除されると、前記係合突部２２は前記位置決め凹部３２内を取付け方向奥側(パチンコ機の前側)に移動するが、係合突部２２が位置決め凹部３２の底面３２ａに当接することはない(図３(b)参照)。すなわち、前記制御基板ケース２１の取外しに際して、前記係合突部２２に過度の負荷が掛かることはなく、該係合突部２２の損傷等を防止できる。
【００４０】
更に、前記係合突部２２を断面円弧状に形成したので、前記位置決め凹部３２の内壁に引っ掛かることなく前記規制部３３との係合の解除を簡単に行なうことができる。また、前記規制部３３の先端部側に形成した切欠部３７により、前記係合突部２２と規制部３３との干渉が低減されて、該係合突部２２を位置決め凹部３２から簡単に抜き出すことができる。このとき、前記規制部３３の先端部を断面円弧状に形成してあるから、前記係合突部２２と規制部３３との干渉をより軽減し得るのでよりスムーズに位置決め凹部３２から抜き出すことができる。
【００４１】
更にまた、前記規制部３３と位置決め凹部３２との連接部３６を、該位置決め凹部３２の開口側に向かうにつれて該規制部３３の先端部側に傾斜するように断面円弧状に凹設したので、前記係合突部２２と規制部３３との係合を円滑に解除することができ、前記制御基板ケース２１の取外し操作を効率よく行なうことができる。また、前記係合突部２２の端部を断面円弧状に形成することで、よりスムーズな操作が可能となる。そして、前記第１係合部２３を前記ケース収容部３１と対向する支持面２１ａに形成すると共に、前記係止フック３４を前記制御基板ケース２１と対向するようケース収容部３１に立設したので、該制御基板ケース２１を取外す際には、両部材２３,３４の延在方向に外力が加わり、両部材２３,３４に掛かる負荷は低減されて耐久性の向上を図り得る。
【００４２】
(制御基板ケースの別の着脱方法)
次に、前記制御基板ケース２１の別の着脱方法について、図４を参照して説明する。先ず、前記制御基板ケース２１に形成した前記第１係合部２３の係止片２３ｂを、前記係止フック３４の爪部３５に係合させる(図４(b))。そして、前記制御基板ケース２１の係合突部２２を、前記セーフ球案内部材３０の側壁部３０ａ(位置決め凹部３２の規制部３３)に当接させた状態で、前記制御基板ケース２１を前方向に押圧して、前記係止フック３４を弾性変形させる。この状態で、前記制御基板ケース２１を前記ケース収容部３１に向けて倒伏させて、該制御基板ケース２１の支持面２１ａが前記位置決め凹部３２に近接する突部３１ａ,３１ａの後端面３１ｂ,３１ｂに当接すると、前記係合突部２２が前記位置決め凹部３２に挿入されて前記規制部３３と係合するので、制御基板ケース２１はケース収容部３１に取付けられる(図４(c))。
【００４３】
なお、前記制御基板ケース２１は前記係止フック３４により右方向の移動が規制されるので、前記位置決め凹部３２から前記係合突部２２が脱離することはない。
【００４４】
このように、前記第１係合部２３と係止フック３４とを係合させた後、前記制御基板ケース２１を前方に押圧するだけで所定の位置に取付けることができ、作業効率の向上を図り得る。また、前記第１係合部２３の係止片２３ｂを断面円弧状に形成したので、前記係止フック３４の傾斜面３４ａに当接した際に該係止片２３ｂが爪部３５に好適に案内され、前記第１係合部２３と係止フック３４とを容易に係合させ得る。更に、前記第１係合部２３の係止片２３ｂを前記係止フック３４の爪部３５と略同等の大きさに設定したので、該係止片２３ｂと爪部３５を係合させた際に、前記制御基板ケース２１が上下方向にずれることなく、前記係合突部２２を容易に前記位置決め凹部３２と対応する位置に臨ませることができる。
【００４５】
また、前記係合突部２２の先端部を断面円形状に形成したので、前記制御基板ケース２１の係合突部２２を、前記位置決め凹部３２の規制部３３に当接させた状態で前記制御基板ケース２１を前方に押圧するだけでも、該制御基板ケース２１の取付けが可能である(図４(b),(c)参照)。すなわち、前方に押圧された断面円弧状に形成された前記係合突部２２の先端部が前記規制部３３に沿って右方向に移動するのに伴って前記制御基板ケース２１の全体が右方向に移動して、前記係止フック３４が弾性変形され、更に前記制御基板ケース２１を前方移動させて前記係合突部２２が前記規制部３３を越えると、該係合突部２２は前記位置決め凹部３２に挿入されると共に、前記係止フック３４が弾性力により元の位置に復帰する。そして、前記係合突部２２と前記規制部３３とが係合して、前記制御基板ケース２１が前記ケース収容部３１に取付けられるので、より簡単な操作で取付けること可能である。ここで、前記規制部３３の先端部も断面円弧状に形成してあるから、前記位置決め凹部３２に前記係合突部２２をよりスムーズに案内することができ、作業効率の更なる向上を図り得る。
【００４６】
また、前記規制部３３の先端部側に形成した切欠部３７に沿って、前記係合突部２２を位置決め凹部３２に確実に挿入させることができる。更に、前記規制部３３と位置決め凹部３２との連接部３６の傾斜により、当該規制部３３は位置決め凹部３２に挿入された前記係合突部２２と確実に係合して前記制御基板ケース２１のガタツキ等を防止し得る。
【００４７】
次に、前記セーフ球案内部材３０からの制御基板ケース２１の取外し方法について説明する。前記制御基板ケース２１を右方向に押圧して前記係止フック３４を弾性変形させ、前記係合突部２２と前記規制部３３との係合を解除する。そして、この状態で該制御基板ケース２１を後方に引張って係合突部２２を規制部３３の後方まで引き出すと共に、前記第１係合部２３と係止フック３４との係合を解除することで、前記制御基板ケース２１を取外すことができる。
【００４８】
ここで、前記係合突部２２の先端部を断面円弧状に形成してあるので、前記ケース収容部３１に取付けられた制御基板ケース２１の左側端縁近傍を把持して後方へ引っ張ると、前記係合突部２２が前記連接部３６および規制部３３に案内され、前記制御基板ケース２１全体が右方向に移動し、前記係止フック３４が弾性変形される。そして前記係合突部２２が前記規制部３３の先端部まで移動すると、該係合突部２２と規制部３３との係合が解錠されると共に、前記第１係合部２３と係止フック３４との係合も解除可能となり、前記制御基板ケース２１を取外すことができる。このように、前記制御基板ケース２１を後方に引っ張るだけで該制御基板ケース２１を前記ケース収容部３１から取外すことができ、作業時間を短縮して作業効率の向上を図り得る。この場合においても、前記規制部３３の先端部が断面円弧状に形成されているから、前記係合突部２２が該規制部３３に案内されてスムーズに取外しができる。
【００４９】
また、前記規制部３３の先端部側に形成した切欠部３７に沿って、前記係合突部２２を一定方向に取外すことができ、取外し作業を円滑に行なうことができる。更に、前記規制部３３と位置決め凹部３２との連接部３６の傾斜により、前記係合突部２２を当該規制部３３の先端部に向かって案内し得るので、より一層効率よく作業を行なうことができる
【００５０】
このように、本実施例の制御基板ケースの取付構造では、一連の簡単な操作で前記セーフ球案内部材３０のケース収容部３１に、前記制御基板ケース２１を取付けたり、取外すことができるようになる。このため、制御基板の交換作業等の作業効率を向上させ得るので、作業時間を短縮することが可能となる。また、制御基板ケース２１を複数の方法で取付けたり、取外すことができるので、パチンコ機Ｐの設置場所や制御基板ケース２１を取付ける位置等により、作業者が所要に応じて該制御基板ケース２１の着脱方法を選択することが可能となり、作業を効率よく行なうことができる。
【００５１】
更に、前記制御基板ケース２１の前記ケース収容部３１を対向する支持面２１ａに前記第１係合部２３を形成すると共に、該ケース収容部３１に制御基板ケース２１と対向するように前記係止フック３４を立設するよう構成してある。このため、例えば前記ケース収容部３１に取付けた前記制御基板ケース２１を大型の制御基板ケース(以下大型ケースと云う)に取替える場合でも、該ケース収容部３１に形成した前記位置決め凹部３２、規制部３３および係止フック３４と対応して該大型ケースに係合突部および第１係合部を形成すれば、セーフ球案内部材３０を取替えることなく着脱可能に取付けることが可能となるので、交換コストの削減や廃棄物の低減を図り得る。
【００５２】
(変更例)
なお、制御基板ケースの取付構造は、実施例の構成のものに限られず、所要に応じて変更することができる。前記制御基板ケースの一端縁に上下方向に離間して一対の平板状の係合突部を形成するようにしたが、その形状や数は所要に応じて決定することができる。そして、各係合突部を挿入し得る大きさに、前記位置決め凹部を前記機能部材に凹設すればよい。
【００５３】
更に、制御基板ケースに丸棒状の係止片を形成した第１係合部を設け、ケース収容部に弾性変形可能なフック状の第２係合部を設けるようにしたが、第１係合部と第２係合部とが係脱可能に係合すれば、その形成位置や形状等は従来公知の何れの形状としてもよい。例えば、制御基板ケースにおける係合突部を形成した端縁と対向する端縁に、外方に向かって第１係合部を突出させ、機能部材に設けたケース収容部における該第１係合部に対応する位置に第２係合部として孔を形成するようにしても、簡単な操作で当該制御基板ケースをケース収容部に対して着脱することができる。
【００５４】
また、前記第１係合部を、制御基板ケースの一端縁に形成した係合突部の延出方向に対して直交する方向(支持面側)に形成すると共に、前記第２係合部を、前記ケース収容部に該制御基板ケースに対向して立設するようにしたが、該第１係合部を係合突部の延出方向に対して交差方向に延出させれば、制御基板ケースの着脱時に両係合部に掛かる負荷が低減されて耐久性の向上を図ることができる。更に、実施例では、ケース収容部に突部を設け、係合突部と規制部とを係合させた際に、該係合突部を挟んで規制部とは反対側に空間が画成されるように、位置決め凹部を形成するようにしたが、その他の構成とすることも可能である。そして、係合突部と位置決め凹部の底面との離間距離は、少なくとも第１係合部と第２係合部との係合が解除された際に、該係合突部と該位置決め凹部の底面とが干渉しない寸法に設定されていれば、当該係合突部に過度の負荷が掛かることなく前記制御基板ケースの取外しが可能である。
【００５５】
例えば図５に示すように、制御基板ケース４１の一端縁において、機能部材におけるケース収容部４５から離間する角部近傍に係合突部４２を形成し、該制御基板ケース４１における係合突部４２と対向する他端縁近傍の支持面４１ａ側に、該支持面４１ａと所要角度傾斜するように第１係合部４３を形成する。そして、前記ケース収容部４５に、前述の実施例と同様に位置決め凹部３２、規制部３３および係止フック３４を夫々形成する。すなわち、前記係合突部４２と規制部３３および第１係合部４３と係止フック３４が夫々係合すると、前記制御基板ケース４１の支持面４１ａは、直接ケース収容部４５に当接するようになっている。この場合も、前記係合突部４１と前記規制部３３とが係合した際に、該係合突部４２と、前記位置決め凹部３２において該規制部３３に対向する底面３２ａとが離間するので、前記制御基板ケース４１を取外す際に、前記係合突部４２が前記位置決め凹部３２の底面３２ａと干渉して損傷するのを防止し得る。
【００５６】
本実施例では、パチンコ機裏側に配設されるセーフ球案内部材に制御基板を保持した制御基板ケースを着脱可能に取付ける場合を示したが、これに限られるものではなく、中枠や機構セット盤、裏カバー部材等の遊技機の裏側に位置して各種部品の取付けに供される部材であれば何れのものであってもよい。更に、本発明に係る制御基板ケースの取付構造を実施する遊技機としては、パチンコ機に限られず、スロットマシン機やアレンジボール機等の各種遊技機に実施することができ、制御基板ケースを着脱可能に取付ける遊技機であればよい。
【００５７】
【発明の効果】
以上説明したように、本発明に係る制御基板ケースの取付構造によれば、制御基板ケースに設けた第１係合部と機能部材のケース収容部に設けた第２係合部との係合を解除する動作、および制御基板ケースに設けた係合突部と側壁部に設けた規制部との係合を解除する動作を、一連の動作で行なうことができるので、制御基板ケースを機能部材から効率的に取外すことができる。また、前記制御基板ケースを前記ケース収容部に取付ける場合にも、煩雑な位置決め操作を行なう必要がなく、作業時間を短縮し得る。更に、第１係合部を、機能部材の底面に対向する支持面に、当該底面に向けて延出して設け、第２係合部を、制御基板ケースに対向するようにケース収容部の底面に立設することで、該制御基板ケースを着脱する際には、両係合部にはその延在方向に外力が加わるので、両係合部に掛かる負荷が低減されて耐久性の向上を図り得る。
【００５８】
前記係合突部と前記規制部とを係合させた際に、該係合突部を挟んで規制部とは反対側に空間が画成されるように、前記位置決め凹部を形成するようにしたので、該制御基板ケースを着脱する際に、該規制部と位置決め凹部の底面とで係合突部が挟まれることなく、当該係合突部に無理な負荷が掛かって損傷等するのを防止できる。更に、第１係合部の係止片を第２係合部の爪部と略同等の大きさに設定したので、該係止片と爪部を係合させた際に、爪部が両支持片の間に位置するから、制御基板ケースがずれることなく、係合突部を容易に位置決め凹部と対応する位置に臨ませることができる。
【００５９】
そして、前記規制部における前記位置決め凹部の開口側の先端部を、該位置決め凹部の開口端より所要長さだけ当該位置決め凹部内に退避させるようにすれば、前記係合突部を前記位置決め凹部に容易に挿入し得るようになると共に、取外しの際に該係合突部を簡単に抜き出すことができる。また、前記規制部における位置決め凹部の開口側の先端部について、前後方向に沿う断面を円弧状に形成することで、前記係合突部の前記位置決め凹部への挿入がスムーズに行なうことができるようになる。更に、前記規制部と前記位置決め凹部との連接部を、該位置決め凹部の開口側に向かうにつれて該規制部の先端部側に傾斜するようにすれば、前記係合突部と当該規制部との係合および係合の解除を、スムーズに行ない得る。更にまた、前記係合突部の先端部について、前後方向に沿う断面を円弧状に形成することで、該係合突部と前記位置決め凹部の内部との接触が低減して、前記規制部との係脱をスムーズに行なうことができるようになる。

[0033]
[Effect of the embodiment]
Next, the operation of the control board case mounting structure according to this embodiment will be described. First, the case where the control board case 21 holding the control board is attached to the safe ball guide member 30 which is located on the back side of the pachinko machine P and used for mounting various components will be described. As shown in FIG. 3A, the safe ball guide member 30 (case housing portion) is formed in a state where the first engaging portion 23 formed on the support surface 21 a of the control board case 21 faces the case housing portion 31. 31) The engaging protrusions 22 and 22 formed on the left edge of the control board case 21 are obliquely inserted into the positioning recesses 32 and 32 provided in the lower side of the side wall 30b formed on the left side of the control board case 31). Insert into. At this time, as shown in FIG. 3 (b), the vicinity of the left end edge of the control board case 21 is formed on the rear end surfaces 31b, 31b of the protrusions 31a, 31a adjacent to the positioning recess 32 formed in the case accommodating portion 31. In addition to abutting each, the locking piece 23b of the first engaging portion 23 formed on the support surface 21a of the control board case 21 contacts the inclined surface 34a of the locking hook 34 formed on the case housing portion 31. .
[0034]
In this state, when the control board case 21 is pressed forward to fall toward the case housing portion 31 with the protrusions 31a and 31a close to the positioning recess 32 as fulcrums, the first engagement The locking piece 23b of the portion 23 presses the inclined surface 34a of the locking hook 34, and the locking hook 34 is elastically deformed. When the support surface 21a of the control board case 21 is laid down until it comes into contact with the rear end surface 31b of the protrusion 31a separated from the positioning recess 32, the locking piece 23b is detached from the inclined surface 34a and the locking hook 34 returns to its original position, and the locking piece 23b engages with the claw portion 35 of the locking hook 34 (see FIG. 3C). Further, the engagement protrusion 22 inserted into the positioning recess 32 of the cover storage portion 31 moves in the positioning recess 32 to the front side (rear side) in the mounting direction, and the restriction provided in the positioning recess 32 is provided. Engage with part 33.
[0035]
That is, when the control board case 21 is attached to the case housing part 31, the control board case 21 is engaged with the engagement between the first engagement part 23 and the locking hook 34, and the engagement protrusion 22. The rearward movement is restricted by the engagement with the restricting part 33, and the support board 21a of the control board case 21 and the protrusion 31a of the case housing part 31 are in contact with each other to restrict the forward movement. The case accommodating portion 31 is stably positioned and held. Since the control board case 21 is restricted from moving in the right direction by the locking hook 34, the engaging protrusion 22 is not detached from the positioning recess 32.
[0036]
  As described above, when the control board case 21 is attached to the case accommodating portion 31, it is not necessary to position the shaft and the hole as in the prior art, so that the control board case 21 can be attached easily and in a short time. Further, when the control board case 21 is attached, it is not necessary to directly insert the engagement protrusions 22 into the positioning recesses 32. For example, the engagement protrusions on the surface of the side wall 30b where the positioning recesses 32 open. When the contact protrusion 22 is moved up and down, the engagement protrusion 22 is naturally inserted when aligned with the positioning recess 32, so that work efficiency is improved. Further, when the engagement protrusion 22 and the restriction portion 33 are engaged, the space 39 is defined on the opposite side of the restriction portion 33 with the engagement protrusion 22 interposed therebetween. A positioning recess 32 is formed, and the engaging protrusion22And the bottom surface 32a facing the restricting portion 33 in the positioning recess 32 are separated from each other. Therefore, when the control board case 21 is attached, the restricting portion 33 and the bottom surface 32a of the positioning recess 32 are engaged. The mating protrusions 22 are not sandwiched, and it is possible to prevent the engaging protrusions 22 from being overloaded and damaged.
[0037]
Since the mounting position is not restricted by the insertion of the engaging protrusion 22 into the positioning recess 32 and the control board case 21 is not displaced in the vertical direction, an efficient operation is possible. Further, the front end portion of the positioning recess 32 on the opening side of the positioning recess 32 is retracted into the positioning recess 32 by a required length from the opening end of the positioning recess 32 to form a notch 37. As a result, positioning when inserting the engaging protrusion 22 into the positioning recess 32 can be facilitated, and work efficiency can be further improved, and the engaging protrusion 22 is inserted into the positioning recess 32 from the rear. In this case, the cutout portion 37 acts as a guide portion and can be easily inserted. Further, by forming the tip end portion of the restricting portion 33 in a circular arc shape, the engaging protrusion 22 that is in contact with the notch portion 37 can be easily inserted into the positioning recess 32. Further, since the engagement protrusion 22 is formed in an arc shape in cross section, the engagement protrusion 22 and the inner wall of the positioning recess 32 are not caught, so that the restriction portion 33 can be smoothly engaged. it can. Furthermore, the engaging protrusion 22 is further inclined by inclining the connecting portion 36 between the restricting portion 33 and the positioning recess 32 toward the distal end side of the restricting portion 33 toward the opening side of the positioning recess 32. Can be smoothly engaged, and the engagement protrusion 22 is reliably engaged, thereby preventing the control board case 21 from rattling or the like.
[0038]
Next, the case where the control board case 21 attached to the case housing part 31 is removed will be described. By grasping the vicinity of the right end portion of the control board case 21 attached to the case accommodating portion 31 and pulling it to the rear side, the engagement between the engagement piece 23a of the first engagement portion 23 and the engagement hook 34 is achieved. Release the match. At this time, the control board case 21 rotates with the protrusions 31a and 31a close to the positioning recess 32 formed in the case housing part 31 as fulcrums, and the engagement protrusion 22 of the control board case 21 and the The engagement with the restricting portion 33 provided in the positioning recess 32 is also released (FIG. 3B). When the control board case 21 is moved rearward as it is, the engagement protrusion 22 is extracted from the positioning recess 32, and the control board case 21 can be removed (FIG. 3A). As described above, since the control board case 21 can be detached only by releasing the engagement between the first engaging portion 23 and the locking hook 34, the working time is shortened and the working efficiency is improved.
[0039]
Here, when the engagement protrusion 22 and the restriction portion 33 are engaged, the space 39 is defined on the opposite side of the restriction portion 33 across the engagement protrusion 22. The positioning recess 32 is formed so that the engaging protrusion 22 does not interfere with the bottom surface 32 a of the positioning recess 32. For this reason, when the control board case 21 is pulled rearward from the case housing portion 31 and the engagement between the first engagement portion 23 and the locking hook 34 is released, the engagement protrusion 22 is The inside of the positioning recess 32 moves to the back side in the mounting direction (front side of the pachinko machine), but the engaging protrusion 22 does not contact the bottom surface 32a of the positioning recess 32 (see FIG. 3B). That is, when the control board case 21 is removed, an excessive load is not applied to the engagement protrusion 22, and damage to the engagement protrusion 22 can be prevented.
[0040]
Furthermore, since the engagement protrusion 22 is formed in a circular arc shape, the engagement with the restriction portion 33 can be easily released without being caught by the inner wall of the positioning recess 32. Further, the notch 37 formed on the tip end side of the restricting portion 33 reduces interference between the engaging protrusion 22 and the restricting portion 33, and the engaging protrusion 22 is easily extracted from the positioning recess 32. be able to. At this time, since the tip of the restricting portion 33 is formed in a circular arc shape, the interference between the engaging protrusion 22 and the restricting portion 33 can be further reduced, so that the positioning recess 32 can be extracted more smoothly. it can.
[0041]
Furthermore, the connecting portion 36 between the restricting portion 33 and the positioning recess 32 is recessed in a circular arc shape so as to be inclined toward the tip end side of the restricting portion 33 toward the opening side of the positioning recess 32. The engagement between the engaging protrusion 22 and the restricting portion 33 can be smoothly released, and the removal operation of the control board case 21 can be performed efficiently. Further, by forming the end of the engaging protrusion 22 in a circular arc shape, a smoother operation is possible. Since the first engaging portion 23 is formed on the support surface 21 a facing the case housing portion 31 and the locking hook 34 is erected on the case housing portion 31 so as to face the control board case 21. When the control board case 21 is removed, an external force is applied in the extending direction of the members 23 and 34, and the load applied to the members 23 and 34 is reduced, so that the durability can be improved.
[0042]
(Another method of attaching / detaching the control board case)
Next, another method for attaching and detaching the control board case 21 will be described with reference to FIG. First, the locking piece 23b of the first engaging portion 23 formed on the control board case 21 is engaged with the claw portion 35 of the locking hook 34 (FIG. 4B). Then, the control board case 21 is moved forward with the engagement protrusion 22 of the control board case 21 in contact with the side wall 30a of the safe ball guide member 30 (the restriction part 33 of the positioning recess 32). And the locking hook 34 is elastically deformed. In this state, the control board case 21 is laid down toward the case housing portion 31, and the rear end faces 31b and 31b of the protrusions 31a and 31a in which the support surface 21a of the control board case 21 is close to the positioning recess 32 are provided. Since the engaging protrusion 22 is inserted into the positioning recess 32 and engages with the restricting portion 33, the control board case 21 is attached to the case accommodating portion 31 (FIG. 4C).
[0043]
Since the control board case 21 is restricted from moving in the right direction by the locking hook 34, the engaging protrusion 22 is not detached from the positioning recess 32.
[0044]
As described above, after the first engaging portion 23 and the locking hook 34 are engaged, the control board case 21 can be attached to a predetermined position simply by pressing forward, thereby improving work efficiency. It can be planned. Further, since the locking piece 23b of the first engagement portion 23 is formed in an arc shape in cross section, the locking piece 23b is suitable for the claw portion 35 when contacting the inclined surface 34a of the locking hook 34. Guided, the first engaging portion 23 and the locking hook 34 can be easily engaged. Further, since the locking piece 23b of the first engaging portion 23 is set to be approximately the same size as the claw portion 35 of the locking hook 34, when the locking piece 23b and the claw portion 35 are engaged, In addition, the engaging projection 22 can be easily brought to a position corresponding to the positioning recess 32 without the control board case 21 being displaced in the vertical direction.
[0045]
Further, since the tip end portion of the engagement protrusion 22 is formed in a circular shape in cross section, the control protrusion 21 of the control board case 21 is in contact with the restriction portion 33 of the positioning recess 32 in the state of the control. The control board case 21 can be attached simply by pressing the board case 21 forward (see FIGS. 4B and 4C). That is, as the tip end portion of the engaging protrusion 22 formed in a circular arc shape pressed forward moves rightward along the restricting portion 33, the entire control board case 21 moves rightward. When the locking hook 34 is elastically deformed and the control board case 21 is further moved forward so that the engaging protrusion 22 exceeds the restricting portion 33, the engaging protrusion 22 is moved to the positioning position. While being inserted into the recess 32, the locking hook 34 returns to its original position by elastic force. And since the said engagement protrusion 22 and the said control part 33 engage, and the said control board case 21 is attached to the said case accommodating part 31, it can be attached by simpler operation. Here, since the tip end portion of the restricting portion 33 is also formed in an arc shape in cross section, the engaging protrusion 22 can be guided more smoothly to the positioning recess 32, and the working efficiency can be further improved. obtain.
[0046]
Further, the engaging protrusion 22 can be reliably inserted into the positioning recess 32 along the notch 37 formed on the distal end side of the restricting portion 33. Further, due to the inclination of the connecting portion 36 between the restricting portion 33 and the positioning recess 32, the restricting portion 33 is reliably engaged with the engaging protrusion 22 inserted into the positioning recess 32, and the control board case 21. It is possible to prevent rattling and the like.
[0047]
Next, a method for removing the control board case 21 from the safe ball guide member 30 will be described. The control board case 21 is pressed in the right direction to elastically deform the locking hook 34, and the engagement between the engagement protrusion 22 and the restriction portion 33 is released. In this state, the control board case 21 is pulled rearward to pull out the engaging protrusion 22 to the rear of the restricting portion 33, and the engagement between the first engaging portion 23 and the locking hook 34 is released. Thus, the control board case 21 can be removed.
[0048]
Here, since the tip end portion of the engaging protrusion 22 is formed in an arc shape in cross section, when the vicinity of the left edge of the control board case 21 attached to the case housing portion 31 is gripped and pulled backward, The engaging protrusion 22 is guided by the connecting portion 36 and the restricting portion 33, the entire control board case 21 is moved rightward, and the locking hook 34 is elastically deformed. When the engagement protrusion 22 moves to the tip of the restriction portion 33, the engagement between the engagement protrusion 22 and the restriction portion 33 is unlocked and the first engagement portion 23 is locked. The engagement with the hook 34 can also be released, and the control board case 21 can be removed. In this way, the control board case 21 can be removed from the case housing part 31 simply by pulling the control board case 21 rearward, thereby shortening the working time and improving the working efficiency. Also in this case, since the tip end portion of the restricting portion 33 is formed in a circular arc shape, the engaging protrusion 22 is guided by the restricting portion 33 and can be smoothly removed.
[0049]
In addition, the engagement protrusion 22 can be removed in a certain direction along the notch 37 formed on the distal end side of the restriction portion 33, and the removal work can be performed smoothly. Furthermore, since the engaging protrusion 22 can be guided toward the tip of the restricting portion 33 by the inclination of the connecting portion 36 between the restricting portion 33 and the positioning recess 32, the work can be performed more efficiently. it can
[0050]
Thus, in the control board case mounting structure of the present embodiment, the control board case 21 can be attached to or removed from the case housing portion 31 of the safe ball guide member 30 by a series of simple operations. Become. For this reason, since work efficiency, such as control board exchange work, can be improved, work time can be shortened. In addition, since the control board case 21 can be attached and detached by a plurality of methods, the operator can adjust the control board case 21 according to the installation location of the pachinko machine P, the position where the control board case 21 is attached, and the like. The attachment / detachment method can be selected, and the work can be performed efficiently.
[0051]
Further, the first engagement portion 23 is formed on a support surface 21 a facing the case housing portion 31 of the control board case 21, and the locking is performed so that the case housing portion 31 faces the control board case 21. The hook 34 is configured to stand upright. For this reason, for example, even when the control board case 21 attached to the case housing part 31 is replaced with a large control board case (hereinafter referred to as a large case), the positioning recess 32 formed in the case housing part 31, the restricting part If the engaging protrusion and the first engaging portion are formed on the large case corresponding to the hook 33 and the locking hook 34, the safe ball guide member 30 can be detachably attached without replacement. Costs and waste can be reduced.
