Description

【０００１】
【発明の属する技術分野】
本発明は、遊技機に関し、特には遊技機の後側（裏側）から遊技盤が着脱可能とされた遊技機に関する。
【０００２】
【従来の技術】
従来、パチンコ遊技機等の遊技機は、図７の断面図に示すように、外枠７１と、前記外枠７１の前面に前方へ開閉可能に取り付けられた前枠７３と、前記前枠７３の後側（裏側又は背面側と同じ）に設けられて前枠７３の閉時に外枠７１内にはまる遊技盤取付枠７５と、前記遊技盤取付枠７５に着脱可能に組み付けられる遊技盤７６と、前記遊技盤取付枠７５の一側縁７７に開閉可能に設けられた機構板７８とを備えるものが一般的である。符号８１は、ガラス扉である。
【０００３】
また、前記機構板７８を外した状態の遊技機裏面を示す図８から理解されるように、前記遊技盤取付枠７５の後面（裏面または背面と同じ）における複数箇所には、前記遊技盤７６を遊技機後面側から着脱可能に固定するための遊技盤固定部材８３が設けられている。前記遊技盤固定部材８３は、その付近Ｂ部を拡大して示す図９及び遊技盤固定部材８３の取付時を示す図１０のように、遊技盤取付枠７５の後面に沿って回動（旋回）可能に設けられた回動式のものからなり、略Ｌ字形の金属板状体に軸着部８４と遊技盤後面押圧部８６及び回動用操作部８８が形成されている。
【０００４】
前記軸着部８４は軸着孔８５を有し、前記遊技盤取付枠７５の後面に立設された軸部材９１が軸着孔８５に挿通されるようになっている。前記遊技盤後面押圧部８６は、前記略Ｌ字形における一端側とされ、前記遊技盤固定部材８４の所要量（所要角度）の回動により、前記遊技盤取付枠７５内への突出量を増大して遊技盤７６の後面７６ａを遊技盤取付枠７５の前方へ押圧し固定するものであり、反対方向への回動により遊技盤取付枠７５内から後退して突出量を減少させ、遊技盤７６を後方へ取り外せるようにするものである。また、前記回動用操作部８８は、前記遊技盤後面押圧部８６とは異なる端部とされ、操作し易いように遊技盤取付枠７５の後方側へ屈曲している。符号９２は遊技盤固定部材８３のガタツキ防止用コイルスプリング、９３はコイルスプリング押圧用ナットである。
【０００５】
【発明が解決しようとする課題】
しかしながら、このような従来の遊技機においては、遊技機の組立や修理などの際、前枠７３を外枠７１に対して閉じた状態（図７、図８又は図９等の状態）で遊技盤固定部材８３を回動させて遊技盤の着脱を行おうとすると、前記遊技盤固定部材８３の回動用操作部８８等が外枠内面７１ａと干渉（衝突）して回動量が制限されるため、遊技盤後面押圧部８６を遊技盤取付枠７５内から後退させることができず、遊技盤取付枠７５内に突出した状態の遊技盤後面押圧部８６に邪魔されて遊技盤７６を遊技盤取付枠７５に対し着脱することができなかった。
【０００６】
したがって、従来では、前記遊技盤７６の着脱に際して、わざわざ前枠７３を外したり前方へ開放したりした後、前記遊技盤固定部材８３を回動させて遊技盤７６の着脱作業を行い、さらにその後に再び前枠７３を閉じねばならず、作業が面倒であった。
【０００７】
本発明はこのような状況に鑑みなされたもので、外枠に対して前枠を外したり開放したりすることなく、前枠を閉じた状態で遊技盤の着脱を行える遊技機を提供する。
【０００８】
【課題を解決するための手段】
請求項１の発明は、外枠と、前記外枠の前面に前方へ開閉可能に取り付けられた前枠と、前記前枠の後側に設けられて前枠の閉時に外枠内にはまる遊技盤取付枠と、前記遊技盤取付枠に着脱可能に固定される遊技盤と、前記遊技盤取付枠の後部複数箇所に設けられて前記遊技盤の着脱時に遊技盤後面側を固定及び固定解除できるように少なくとも一部が可動とされた遊技盤固定部材とを備える遊技機であって、前記前枠閉状態における遊技盤固定部材が遊技盤固定状態から固定解除状態まで動く際に、前記遊技盤固定部材の外枠内に位置する部分が動く領域よりも遊技盤固定部材の外方側に該遊技盤固定部材付近の外枠内面が位置することとなるように、前記遊技盤固定部材を設け、該遊技盤固定部材が、前記遊技盤取付枠への軸着部と、該軸着部周囲に形成された遊技盤後面押圧部及び回動用操作部とを有し、前記回動用操作部による遊技盤固定部材の回動で前記遊技盤取付枠内への前記遊技盤後面押圧部の突出量増大及び該突出量減少を行うように回動可能に軸着されたものであって、前記回動による前記遊技盤後面押圧部の突出量増大で前記遊技盤の後面側が固定され、前記突出量減少で前記遊技盤の後面側の固定が解除され、前記遊技盤固定部材の回動用操作部が、軸着部と前記遊技盤後面押圧部のある前記遊技盤固定部材の本体部から前記遊技盤取付枠の後方側へ形成された延長腕部分と、該延長腕部分に対して交差する方向へ延長腕部分から形成されたレバー部分とよりなるとともに、該レバー部分の遊技盤取付枠前方側縁部が前枠閉時における外枠後面と面一または該外枠後面よりも後方側に位置することを特徴とする遊技機に係る。
【０００９】
請求項２の発明は、請求項１において、前記遊技盤固定部材の回動中心が、遊技盤後面押圧部側端部よりも該遊技盤後面押圧部とは反対側端部近くに位置することを特徴とする。
【００１０】
請求項３の発明は、請求項１又は２において、前記延長腕部分が前記遊技盤後面押圧部の側部から形成されていることを特徴とする。
【００１１】
【発明の実施の形態】
以下添付の図面に基づき本発明の好適な実施形態を説明する。図１は本発明の一実施例の遊技機を示す正面図、図２は図１の遊技機における機構板開放状態を示す断面図、図３は図１の遊技機の機構板を外した状態を示す後面図、図４は図３のＡ部を示す斜視図、図５は図４における遊技盤固定部材の取付時を示す斜視図、図６は遊技盤固定部材の回動を示す図である。
【００１２】
図１及び図２に示す遊技機１は、パチンコ遊技機であり、外枠２内に着脱可能に遊技盤３が組み付けられている。前記遊技盤３の縁には遊技球の外側ガイドレール４及び内側ガイドレール５が略円形に立設され、前記内側ガイドレール５によって囲まれた遊技領域６に、普通図柄表示装置８、特別図柄表示装置９、各種の入賞口及び発射装置３１等を備える。
【００１３】
入賞口としては、特別図柄表示装置９の下方に上側第１種始動入賞口１０、普通電動役物で可動片を有する下側第１種始動入賞口１１、特別電動役物である大入賞口１５が配設され、また、前記上側及び下側第１種始動入賞口１０，１１の左右には左袖入賞口２３と右袖入賞口２５、前記大入賞口１５の両側には左落とし入賞口２７と右落とし入賞口２９が配設されている。そして、発射装置３１の操作ハンドル３２の操作により発射された遊技球が外側ガイドレール４と内側ガイドレール５間の通路を通って遊技領域内に発射され、転動しながら落下し、前記入賞口へ入ると、所定数の賞球遊技球が球払出口３６から上受け皿３８上に払い出されるようになっている。
【００１４】
前記特別図柄表示装置９の左右には普通図柄変動開始用左ゲート１９及び普通図柄変動開始用右ゲート２１が設けられ、該普通図柄変動開始用左ゲート１９及び普通図柄変動開始用右ゲート２１に遊技球が入球することにより前記普通図柄表示装置８で普通図柄が変動し、特定の普通図柄で停止することによって、小当たりとなって、前記下側第１種始動入賞口１１が拡開開放し遊技球が入球し易くなる。
【００１５】
また、前記第１種始動入賞口１０，１１に遊技球が入球すると、前記特別図柄表示装置９で特別図柄が変動し、特定の組合せの図柄で停止すると、大当たりになって大入賞口１５が所定回数開閉を繰り返して遊技球を入球し易くし、入球ごとに所定数の遊技球が払い出されるようになっている。
【００１６】
前記遊技盤を収容する外枠２は、所要の奥行きを有する枠形状からなり、前面には前方へ開閉可能に前枠４１が取り付けられている。この前枠４１の取り付けは、前枠４１と外枠２の一側縁（この例では左側側部）上下をヒンジ部材Ｈ（図１に示す）で連結することにより行われている。前記前枠４１は、前面周縁が装飾面とされて飾りランプ等が設けられ、中央部にはガラス扉４２が開閉可能に設けられる。このガラス扉４２は、その一側縁（この例では左側側部）がヒンジ部材（図示せず）で前枠４１の一側縁（左側側部）に連結されている。
【００１７】
前記前枠４１の後側には、前枠４１を外枠２に対して閉じた時に外枠２内となる位置に遊技盤取付枠４３が固定される。この遊技盤取付枠４３は、前記遊技盤３を着脱可能に取り付けるためのものである。この実施例の遊技盤取付枠４３は、前記前枠４１と別体とされ、ネジ等で前枠４１後面に固定されているが、遊技盤取付枠４３と前枠４１をプラスチック等で一体に形成してもよい。
【００１８】
前記遊技盤取付枠４３には後側から遊技盤３が着脱可能に取り付けられるとともに、一側縁（この例では左側側部）にヒンジ部材６５を介して機構板４５が開閉可能に取り付けられている。なお、前記機構板４５にはこの遊技機１の作動に必要な各種の基盤や装置等が設けられる。
【００１９】
前記遊技盤３の着脱は、前記機構板４５を外した状態の遊技機背面を示す図３から理解されるように、前記遊技盤取付枠４３の後面４４所要位置、この例では左右の上下位置における計４箇所に設けられた遊技盤固定部材５０によって行われる。前記遊技盤固定部材５０は、図３のＡ部を示す図４及び遊技盤固定部材の取付時を示す図５からわかるように、前記遊技盤取付枠４３の後側から遊技盤取付枠４３内に挿入された遊技盤３の後面３ａを押圧し、前記遊技盤取付枠４３の前部内周に形成された支持部４３ａとの間で遊技盤３の縁を挟持して遊技盤３を固定し、また前記の押圧解除により遊技盤３を後方へ取り外せるようにするものである。
【００２０】
この実施例における遊技盤固定部材５０は、本体部５１と、該本体部５１から一体に形成された回動用操作部５８とよりなる。前記本体部５１は、略長方形の一端側が円弧とされた長形金属片の一端側に軸着部５２が形成され、反対側には遊技盤後面押圧部５５が形成されたものからなる。
【００２１】
前記軸着部５２は、前記金属片の一端側に金属片の表裏を貫通する軸部材挿通筒部５３が嵌着された構成とされ、前記軸部材挿通筒部５３の周壁で包囲される軸部材挿通孔５４を内部に有する。この軸部材挿通孔５４には、前記遊技盤取付枠４３の後面４４所要位置に立設された軸部材６１が挿通され、該軸部材６１外周に装着された遊技盤固定部材押圧用コイルスプリングＳと、該コイルスプリングＳを本体部５１側へ押しつけて圧縮状態とするように軸部材６１先端に螺着されたナットＮとにより、この遊技盤固定部材５０が前記軸部材挿通孔５４の中心（軸部材６１中心と等しい）を回動中心Ｃとして遊技盤取付枠後面４４に沿って回動（旋回）可能に保持される。
【００２２】
前記のように遊技盤固定部材５０における回動中心Ｃを、遊技盤後面押圧部側端部５５ａよりも遊技盤後面押圧部５５とは反対側端部５２ａに近い位置となるようにしたため、前記遊技盤固定部材５０の一方向（この例では上方）への回動により遊技盤後面押圧部５５が遊技盤取付枠４３内への突出量を増し、逆方向（この例では下方）への回動により後退して突出量を減少させることができるようになり、それとともに、前記遊技盤後面押圧部５５とは反対側端部５２ａ外周の回動半径ｒが小さくなって、前記前枠４１閉状態（図１〜５等の状態）における遊技盤固定部材５０の回動時に該遊技盤固定部材５０が外枠内面２ａと干渉し難くなる。さらに、この実施例では前記遊技盤後面押圧部５５の突出量減少時に遊技盤後面押圧部５５が遊技盤取付枠４３の内面４３ｂから突出しなくなるように、前記遊技盤固定部材５０の回動中心Ｃが遊技盤取付枠内面４３ｂから所要量離れた位置に設定されている。なお、この実施例では前記遊技盤後面押圧部５５が遊技盤取付枠４３内から完全に後退した（遊技盤取付枠４３の後面４４と完全に重なった）時に、初めて前記遊技盤３の着脱が可能となるが、それに限るものではない。すなわち、前記遊技盤３が遊技盤取付枠４３の内面４３ｂ寸法よりも所要量小さくされて遊技盤取付枠内面４３ｂとの間に隙間があるような場合には、前記遊技盤後面押圧部５５の突出量減少時に遊技盤後面押圧部５５が完全に遊技盤取付枠４３から後退ぜず、遊技盤取付枠４３内に一部突出した状態でも、その一部突出部分と干渉することなく遊技盤３の着脱が可能となることもある。
【００２３】
前記遊技盤後面押圧部５５は、前記軸着部５２とは反対側端部で構成されている。この遊技盤後面押圧部５５は、一方向（この例では上方）への回動により、前記遊技盤取付枠４３内への突出量が増大して遊技盤後面３ａを押圧し、反対方向（下方）への回動により突出量が減少して遊技盤取付枠４３の後面４４に重なることにより遊技盤後面３ａの押圧を解除するようになっている。前記突出時の回動方向側（上方側）となる遊技盤後面押圧部５５の側部は、前記遊技盤取付枠４３の後方側へ傾斜した遊技盤押圧容易化爪５６となっており、前記突出量増大方向への回動時に遊技盤後面３ａが遊技盤取付枠後面４４よりも少し後方へ飛び出ている場合にも、その飛び出ている遊技盤３の縁を遊技盤押圧容易化爪５６によって容易に乗り越えられるようになっている。
【００２４】
なお、前記遊技盤後面押圧部５５の前面には遊技盤後面３ａの押圧力を高めるための凸部５７が形成されている。また、前記本体部５１の軸着部側端部５２ａ周縁は、前記遊技盤固定部材５０の回動時に外枠内面２ａとぶつかりにくいように円弧状にされている。
【００２５】
前記回動用操作部５８はこの遊技盤固定部材５０を回動させる際の操作部を構成するもので、この例では前記本体部５１の側部から遊技盤取付枠４３の後方側へ折り曲げられた延長腕部分５９と、該延長腕部分５９に対して交差するように延長腕部分５９から屈曲形成されたレバー部分６０とで構成されている。
【００２６】
前記延長腕部分５９は、この遊技盤固定部材５０の回動操作を容易にするとともに、前記遊技盤後面押圧部５５の突出量を減少させる回動時に延長腕部分５９が外枠内面２ａと干渉するのを効率良く防ぐため、前記軸着部５２とは反対側となる遊技盤後面押圧部５５の側部（この例では前記遊技盤押圧容易化爪５６とは反対側の側部）に形成されている。
【００２７】
前記レバー部分６０は、該レバー部分６０における遊技盤取付枠前方側縁部６０ａが前記前枠４１閉時における遊技盤固定部材５０付近の外枠後面２ｂと面一又は該後面２ｂよりも後方に位置するようになっている。このようにすることによって、図６に示すように、前記遊技盤３着脱の際に遊技盤固定部材５０を遊技盤固定状態（Ａ図）から固定解除状態（Ｂ図）へ回動させる時、この図のように前記前枠４１が外枠２に対して閉状態であっても、前記レバー部分６０が外枠後面２ｂより後方で回動するために遊技盤固定部材５０付近の外枠内面２ａとレバー部分６０が干渉しなくなる。
【００２８】
さらに前記遊技盤固定部材５０は、前記前枠４１閉状態における遊技盤固定状態から固定解除状態まで回動する際に、前記遊技盤固定部材５０の外枠２内に位置する部分５０ａ（この例では前記本体部５１及び延長腕部分５９）が動く領域（横切る空間あるいは外枠２内に位置する部分５０ａの外周面が形成する軌跡とも言える部分であり、鎖線Ｌで囲まれる範囲に相当する。）よりも、前記遊技盤固定部材５０付近の外枠内面２ａが遊技盤固定部材５０の外方側に位置することとなるように、前記遊技盤取付枠後面４４での軸着位置が定められている。そのため、前記前枠４１を閉じた状態でも、前記遊技盤固定部材５０を遊技盤固定状態（図６のＡ図）から固定解除状態（固定解除に必要な状態、図６のＢ図）まで前記遊技盤後面押圧部５５の突出量が減少する方向へ回動させる際に、前記遊技盤固定部材５０が外枠内面２ａと干渉しなくなり、前記遊技盤３の着脱が可能となる。なお、この実施例では、前記固定解除方向へ遊技盤固定部材５０を回動させる際、前記固定解除可能に至った後にさらに余分に回動を続けると、前記遊技盤固定部材５０の一部が外枠内面２ａと干渉してそれ以上遊技盤固定部材５０が回動しないようになっており、それによって回動操作の無駄が防がれている。
【００２９】
なお、本発明は、前記実施例に限られるものではなく、本発明の趣旨を逸脱しない範囲で適宜変更されてもよい。例えば、前記遊技盤固定部材は、実施例のような回動式のものに限られず、一部が揺動して遊技盤の固定及び固定解除するもの、あるいはその他のものであってもよい。
【００３０】
【発明の効果】
以上図示し説明したように、請求項１〜３の発明に係る遊技機によれば、前枠を閉じた状態で遊技機後方側から遊技盤を着脱する際に、遊技盤固定部材が外枠内面と干渉しないため、前枠を外したり開けたりすることなく作業を行え、効率的である。また、前記遊技盤固定部材が回動式のものであるため、構造が簡単で安価であるのみならず遊技盤の着脱を容易かつ確実に行うことができる。さらに、前記遊技盤固定部材の回動用操作部におけるレバー部分が、遊技盤固定部材の回動時に外枠内面と干渉せず、遊技盤固定部材の回動を妨げることがない。
【００３１】
さらに請求項２の発明に係る遊技機によれば、遊技盤固定部材の回動中心が遊技盤後面押圧部側端部よりも該遊技盤後面押圧部とは反対側端部に近い位置にあるため、前枠を閉じた際に遊技盤固定部材と外枠内面間が接近していても、遊技盤固定解除状態への回動時に遊技盤後面押圧部とは反対側端部外周面の回動半径が小さくなって遊技盤固定部材が外枠内面と当たり難くなり、遊技盤固定部材と外枠の干渉をより確実に防止し易くなる。しかも、前記遊技盤固定部材と外枠内面との干渉を防ぐために外枠を大きくしたり、遊技盤取付枠を小さくしたりする必要がないので、従来の外枠や遊技盤取付枠等をそのまま使用することができる。
【００３２】
さらに請求項３の発明に係る遊技機によれば、回動用操作部の延長腕部分が遊技盤後面押圧部の側部から形成されているため、遊技盤後面押圧部が外枠内面近くへ回動するまで延長腕部分が外枠内面に近づかないので、遊技盤固定部材の回動時に外枠内面と延長腕部分の干渉をより確実に防ぐことができるようになる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a gaming machine, and more particularly to a gaming machine in which a game board is detachable from a rear side (back side) of the game machine.
[0002]
[Prior art]
Conventionally, as shown in a cross-sectional view of FIG. 7, a gaming machine such as a pachinko gaming machine includes an outer frame 71, a front frame 73 attached to a front surface of the outer frame 71 so as to be openable and closable forward, and a front frame 73.

The rear face 3a of the game board 3 inserted into the game board 3 is pressed, and the edge of the game board 3 is clamped between the game board 3 and a support portion 43a formed on the inner periphery of the front part of the game board mounting frame 43, thereby fixing the game board 3. Further, the game board 3 can be detached rearward by releasing the pressing.
[0020]
The game board fixing member 50 in this embodiment includes a main body 51 and a rotating operation section 58 integrally formed from the main body 51. The main body 51 is formed by forming a shaft attaching portion 52 on one end side of a long rectangular metal piece having a substantially rectangular arc on one end side, and a game board rear surface pressing portion 55 on the opposite side.
[0021]
The shaft attachment portion 52 has a configuration in which a shaft member insertion tube portion 53 penetrating the front and back of the metal piece is fitted to one end side of the metal piece, and a shaft surrounded by a peripheral wall of the shaft member insertion tube portion 53. It has a member insertion hole 54 inside. A shaft member 61 erected at a required position on the rear surface 44 of the game board mounting frame 43 is inserted into the shaft member insertion hole 54, and a game board fixing member pressing coil spring S mounted on the outer periphery of the shaft member 61 is inserted. And the nut N screwed to the tip of the shaft member 61 so as to press the coil spring S against the main body 51 to be in a compressed state. (Equal to the center of the shaft member 61) as a rotation center C, and is held rotatably (turnable) along the rear surface 44 of the game board mounting frame.
[0022]
As described above, the center of rotation C of the game board fixing member 50 is located closer to the end 52a opposite to the game board rear pressing portion 55 than the game board rear pressing portion side end 55a. By rotating the game board fixing member 50 in one direction (upward in this example), the rearward pressing portion 55 of the game board increases the amount of projection into the game board mounting frame 43, and turns in the opposite direction (downward in this example). As a result, the amount of protrusion can be reduced by the movement, and at the same time, the turning radius r of the outer periphery of the end portion 52a on the opposite side to the game board rear surface pressing portion 55 decreases, and the front frame 41 closes. When the game board fixing member 50 rotates in the state (the state of FIGS. 1 to 5 and the like), the game board fixing member 50 does not easily interfere with the outer frame inner surface 2a. Further, in this embodiment, the rotation center C of the game board fixing member 50 is set such that the game board rear face pressing part 55 does not protrude from the inner surface 43b of the game board mounting frame 43 when the projection amount of the game board rear face pressing part 55 decreases. Are set at positions separated by a required amount from the inner surface 43b of the game board mounting frame. In this embodiment, when the game board rear pressing portion 55 is completely retracted from the inside of the game board mounting frame 43 (completely overlaps with the rear face 44 of the game board mounting frame 43), the game board 3 is not attached or detached for the first time. Yes, but not limited to. That is, when the gaming board 3 is required to be smaller than the inner surface 43b of the gaming board mounting frame 43 by a required amount and there is a gap between the gaming board 3 and the inner surface 43b of the gaming board mounting frame 43, When the projection amount decreases, the game board rear surface pressing portion 55 does not completely retreat from the game board mounting frame 43, and even if it partially projects into the game board mounting frame 43, the game board 3 does not interfere with the partially projecting portion. May be removable.
[0023]
The game board rear surface pressing portion 55 is formed at an end opposite to the shaft attachment portion 52. By rotating in one direction (upward in this example), the rearward pressing portion 55 of the game board increases the amount of protrusion into the game board mounting frame 43 and presses the rear face 3a of the game board. ), The amount of protrusion decreases and overlaps with the rear surface 44 of the game board mounting frame 43 to release the pressing of the game board rear face 3a. A side portion of the game board rear surface pressing portion 55 which is on the rotation direction side (upper side) at the time of the projection is a game board pressing facilitation claw 56 inclined to the rear side of the game board mounting frame 43, Even when the rear surface 3a of the game board protrudes slightly rearward from the rear surface 44 of the game board mounting frame when rotating in the direction of increasing the amount of protrusion, the edge of the game board 3 protruding from the rear face 3a is pressed by the game board pressing facilitation claw 56. It is easy to get over.
[0024]
A convex portion 57 for increasing the pressing force of the game board rear surface 3a is formed on the front surface of the game board rear surface pressing portion 55. The peripheral edge of the end portion 52a of the main body 51 on the shaft-attached portion is formed in an arc shape so that it does not easily hit the inner surface 2a of the outer frame when the game board fixing member 50 rotates.
[0025]
The turning operation part 58 constitutes an operating part when the game board fixing member 50 is turned. In this example, the turning operation part 58 is bent from the side of the main body 51 to the rear side of the game board mounting frame 43. It is composed of an extended arm portion 59 and a lever portion 60 bent from the extended arm portion 59 so as to intersect with the extended arm portion 59.
[0026]
The extension arm portion 59 facilitates the turning operation of the game board fixing member 50, and also causes the extension arm portion 59 to interfere with the outer frame inner surface 2a at the time of turning to reduce the protrusion amount of the game board rear surface pressing portion 55. In order to efficiently prevent the game panel from being pressed, a side portion of the game board rear surface pressing portion 55 opposite to the shaft attachment portion 52 (in this example, a side portion opposite to the game board pressing facilitation claw 56) is formed. Have been.
[0027]
The lever portion 60 is flush with the outer frame rear surface 2b near the game board fixing member 50 when the front frame 41 is closed, or the rear edge of the rear surface 2b. It is located. By doing so, as shown in FIG. 6, when the game board fixing member 50 is rotated from the game board fixed state (FIG. A) to the unlocked state (FIG. B) when the game board 3 is attached and detached, As shown in this figure, even when the front frame 41 is closed with respect to the outer frame 2, the lever portion 60 rotates behind the rear surface 2b of the outer frame, so the inner surface of the outer frame near the game board fixing member 50. 2a and the lever portion 60 do not interfere with each other.
[0028]
Further, when the game board fixing member 50 rotates from the game board fixed state in the front frame 41 closed state to the unlocked state, the portion 50a of the game board fixing member 50 located in the outer frame 2 (this example). Is a locus formed by a region in which the main body 51 and the extended arm portion 59 move (a crossing space or an outer peripheral surface of a portion 50a located in the outer frame 2), and corresponds to a range surrounded by a chain line L. ), The outer frame inner surface 2a near the game board fixing member 50 is located on the outer side of the game board fixing member 50. ing. Therefore, even when the front frame 41 is closed, the game board fixing member 50 is fixed from the game board fixed state (FIG. 6A) to the unlocked state (the state required for unlocking, FIG. 6B). When rotating the game board rear surface pressing portion 55 in the direction in which the projecting amount decreases, the game board fixing member 50 does not interfere with the outer frame inner surface 2a, and the game board 3 can be attached and detached. In this embodiment, when the game board fixing member 50 is rotated in the unlocking direction, if the game board fixing member 50 is further rotated after reaching the unlockable state, a part of the game board fixing member 50 The game board fixing member 50 is prevented from rotating any more by interfering with the inner surface 2a of the outer frame, thereby preventing waste of the rotating operation.
[0029]
It should be noted that the present invention is not limited to the above embodiment, and may be appropriately changed without departing from the spirit of the present invention. For example, the game board fixing member is not limited to the rotary type as in the embodiment, but may be a member that partially swings to fix and release the game board, or may be another type.
[0030]
【The invention's effect】
As shown and described above, according to the gaming machine according to the first to third aspects of the present invention, when the game board is attached or detached from the rear side of the game machine with the front frame closed, the game board fixing member is attached to the outer frame. Since it does not interfere with the inner surface, work can be performed without removing or opening the front frame, which is efficient. Further, since the game board fixing member is a rotary type, not only is the structure simple and inexpensive, but also the game board can be easily and reliably attached and detached. Further, the lever portion of the rotating operation portion of the game board fixing member does not interfere with the inner surface of the outer frame when the game board fixing member rotates, and does not hinder the rotation of the game board fixing member.
[0031]
Further, according to the gaming machine according to the invention of claim 2, in a position close to the opposite end the rotation center of the game board fixing member is a the recreation board rear pressing portion than the game board rear surface pressing portion end Therefore, even when the game board fixing member and the inner surface of the outer frame are close to each other when the front frame is closed, when the game board is rotated to the unlocked state, the outer peripheral surface of the end opposite to the pressing portion on the rear face of the game board is turned. The moving radius is reduced, so that the game board fixing member does not easily come into contact with the inner surface of the outer frame, and the interference between the game board fixing member and the outer frame is more easily prevented. Moreover, there is no need to increase the outer frame or reduce the size of the game board mounting frame in order to prevent interference between the game board fixing member and the inner surface of the outer frame. Can be used.
[0032]
Further, according to the gaming machine of the third aspect of the present invention, since the extended arm portion of the rotating operation portion is formed from the side of the rear pressing portion of the game board, the rear pressing portion of the gaming board is turned near the inner surface of the outer frame. Since the extended arm portion does not approach the inner surface of the outer frame until it moves, it is possible to more reliably prevent the interference between the inner surface of the outer frame and the extended arm portion when the game board fixing member rotates.
