【発明の属する技術分野】
本発明は、パチンコ機、スロットマシーン等の遊技機に関するものである。
【0002】
【従来の技術】
通常のパチンコ機は、周囲が外枠で覆われており、その外枠の前方に、遊技盤や機構板等を設置したミドル枠が、片開き自在に取り付けられている。また、ミドル枠には、施錠機構が設けられており、通常は、ミドル枠が、外枠に対して閉じた状態でロックされており、ロックを解除した場合にのみ、外枠に対して片開きできるようになっている。図7は、ミドル枠に設けられた施錠機構の一部を示したもの(パチンコ機の裏面側から一部を省略して示したもの)であり、外枠51の片側の端縁には、係合片52,52が上下に設けられている。また、ミドル枠(図示せず)の開放側の端縁には、上下一対の鉤部材53,53が回動自在に枢着されており、基端が連結部材54によって連結されている。各鉤部材53,53は、連結部材54を上下動させることによって、パチンコ機の前面と直交する鉛直面内において回動し、外枠51に設けられた各係合片52,52と係脱するようになっている。さらに、連結部材54は、常時、下方に付勢されており、各鉤部材53,53が外枠51の係合片52,52と係合するように付勢されており、ミドル枠が外枠51に対して閉じた状態でロックされている。そして、連結部材54に付設された施錠装置(図示せず)のカムを回動操作し、連結部材54を上方にスライドさせることによって、ミドル枠を外枠51に対して片開きできるようになっている。なお、ミドル枠に設置されている機構板(図示せず)には、パチンコ機の遊技内容を制御する制御基板が装着されている。かかるパチンコ機は、通常、カードリーダ装置(あるいは球貸装置)55を左隣りに付設した状態で、パチンコホールの島設備に設置して使用される(したがって、パチンコ機の右側には、別のパチンコ機のカードリーダ装置55が隣り合うことになる)。
【0003】
【発明が解決しようとする課題】
しかしながら、上記従来のパチンコ機においては、図7(a)の如く、先端に水平なコ字状の折り返しを垂設した扁平な長尺状の器具56(以下、「こじ開け器具」という)を、上方から、外枠51と隣のパチンコ機のカードリーダ装置55との隙間に挿入し、図7(b)の如く、ミドル枠に付設されている鉤部材53を無理矢理押し下げ、ミドル枠を片開きし、機構板に装着されている制御基板を別のものに取り替える、という不正行為(以下、「ミドル枠こじ開け不正」という)が行われることがある。
【0004】
本発明の目的は、上記従来のパチンコ機が有する問題点を解消し、「ミドル枠こじ開け不正」を効果的に防止することが可能な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】
かかる本発明の構成は、前面に遊技盤を設け裏面に機構板を設けたミドル枠が、その上下左右を囲む外枠に対して片開き自在に取り付けられているとともに、外枠に係合片が設けられており、かつ、ミドル枠に、外枠の係合片と係脱する鉤部材を有する施錠機構が設けられており、鉤部材を係合片に係合させることにより、ミドル枠が外枠に対して閉じた状態で保持され、鉤部材と係合片との係合を解除することにより、ミドル枠が外枠に対して片開き可能となる遊技機であって、前記係合片が、前記外枠の内面と当接する支持部の後端縁に平板状の螺着部を垂直に延設し、かつ、前記支持部に前記鉤部材を覆う不正防止カバーを帯状に垂設し、なおかつ、その不正防止カバーの前端縁および後端縁を鉛直下方に折り曲げたものであるとともに、外枠の後端縁に位置した前記係合片の螺着部に、前記外枠から外側に突出自在で任意の突出位置で固定可能な不正防止プレートが当接するように設けられていることにある
【0006】
【発明の実施の形態】
以下、本発明の遊技機の一実施形態であるパチンコ機を、図面に基づいて詳細に説明する。
【0007】
図1は、パチンコ機1の正面を示したものであり、図2、図3は、それぞれ、図1におけるA−A線断面、B−B線断面を示したものである。パチンコ機1は、上下面および左右両側面が外枠2によって覆われており、金属製のミドル枠3が、外枠2に対して、左端縁を軸として片開き自在に取り付けられている。また、ミドル枠3には、各種の入賞装置を設置し多数の障害釘を植設した遊技盤29が取り付けられているとともに、遊技球払出装置等を設置した機構板28が取り付けられている。加えて、ミドル枠3の前方には、前面枠4が設置されており、前面枠4の下方には、上皿部5、下側機能部6が設置されている。さらに、ミドル枠3は、右端縁に、鉤部材10a,10b、連結部材9、カム12、施錠装置13、バネ部材(コイルバネ)11,11等からなる施錠機構7が設けられている。
【0008】
鉤部材10a,10bは、先端が矢尻状になっている。また、中央よりやや前方の部分がピン19によってミドル枠3に枢着されており、ピン19を中心として回動自在になっている。さらに、各鉤部材10a,10bは、基端が、連結部材9によって、連結されており、その連結部材9は、バネ部材11,11によって、常時、下方に付勢された状態になっている。このため、各鉤部材10a,10bは、常時、先端が上方へ付勢された状態になっている。なお、連結部材9は、ストッパ18によって、所定位置より下方まで下がらないようになっており、各鉤部材10a,10bの先端が、所定位置より上方まで上がらないようになっている。さらに、連結部材9の下端際には、施錠装置13が設けられており、後方に位置したカム12の先端が、連結部材9の下端際に穿設された作用孔20に嵌入した状態になっている。
【0009】
一方、図4は、外枠2および施錠機構の一部をパチンコ機1の裏面側から示したものであり、外枠2の右端縁(パチンコ機1の正面から見た場合の右端縁)の上下には、断面L字状の係合片8,8、および不正防止プレート17,17が設置されている。図5は、係合片8、不正防止プレート17を示したものであり、係合片8は、金属板を折り曲げ形成したものであり、平板状の支持部21の後端縁に、平板状の螺着部22が垂直に延設されている。また、螺着部22の中央には、位置決めタブ23が突設されており、位置決めタブ23の上下には、ネジ孔24,24が穿設されている。一方、支持部21の前端縁(図面の右側)の下方には、係合部14が内向きに立設されている。さらに、支持部21の下端縁には、不正防止カバー15が帯状に垂設されており、係合部14の上端から後方にかけて下向きに傾斜した状態になっている(鉤部材10a,10bの先端と同じ角度で傾斜した状態になっている)。また、不正防止カバー15の後端は、鉛直下方に折れ曲がった状態になっている。
【0010】
一方、不正防止プレート17は、係合片8の螺着部22と略同一の形状を有しており、螺着部22の位置決めタブ23、ネジ孔24,24に対応する位置に、3つの水平な長孔26,26・・が穿設されている。各係合片8,8は、螺着部22の位置決めタブ23を、中央の長孔26に挿通させるようにして不正防止プレート17を積層した状態で、不正防止プレートの上下の長孔26,26、および螺着部22のネジ孔24,24を利用して、外枠2の右端縁の上下の後面に螺着されている。そして、支持部21が外枠2の内面に当接し、係合部14、不正防止カバー15が、内向きに突出した状態になっている。
【0011】
かかるパチンコ機1は、片開きしているミドル枠3を外枠2に対して閉じるように押し込むと、各鉤部材10a,10bの先端の傾斜部分が、外枠2に設けられた係合片8,8の係合部14,14の下端に衝突し、各鉤部材10a,10bが、先端を下に向けるように鉛直面内を回動するとともに、連結部材9が、バネ部材11,11の付勢力に抗して上昇する。そして、ミドル枠3が完全に閉じられると、各鉤部材10a,10bの切り欠き16に、それぞれ、外枠2に設けられた係合片8,8の係合部14,14が係合可能な状態となるため、バネ部材11,11によって付勢されている連結部材9が下降するとともに、各鉤部材10a,10bが、先端を上に向けるように回動する。そして、各鉤部材10a,10bの切り欠き16に、それぞれ、各係合片8,8の係合部14,14が係合すると、ミドル枠3が、外枠2に対して閉じた状態でロックされる(図4参照)。
【0012】
なお、施錠装置13の鍵穴27に適合した鍵(図示せず)を挿入して所定位置まで回転させた場合には、カム23が回転し、そのカム23の回転に伴って、連結部材9がバネ部材11,11の付勢力に抗して上昇し、各鉤部材10a,10bが、先端を下に向けるように回動する(図6参照)。このため、各鉤部材10a,10bの切り欠き16,16と外枠2に設けられた各係合片8,8の係合部14,14との係合が解除され、ミドル枠3を外枠2に対して片開きすることが可能となる。
【0013】
また、ミドル枠3が外枠2に対して閉じた状態でロックされた場合には、図4の如く、各鉤部材10a,10bの先端が、それぞれ、外枠2の係合片8,8に設けられた不正カバー15,15で覆われた状態になる(各鉤部材10a,10bの先端の後側に、不正防止カバー15が垂直に配置した状態になる)。したがって、図4の如く、左側(パチンコ機1の正面から見た場合の左側)にカードリーダ装置(あるいは球貸装置)25を付設した状態で、パチンコホールの島設備に設置した後(すなわち、右側に別のパチンコ機のカードリーダ装置(あるいは球貸装置)を隣り合わせるようにパチンコホールの島設備に設置した後)に、上方から「こじ開け器具」を外枠2と隣のパチンコ機のカードリーダ装置(あるいは球貸装置)との隙間に挿入させても、不正防止カバー15,15が障害物となり、「こじ開け器具」の先端で鉤部材10a,10bを押し下げることができない。
【0014】
一方、パチンコ機1は、左側にカードリーダ装置(あるいは球貸装置)25を付設した状態でパチンコホールの島設備に設置する際に、島設備上の関係で、外枠2と隣のパチンコ機のカードリーダ装置(あるいは球貸装置)との間隔が若干広くなってしまう場合でも、係合片8,8を外枠2に螺着しているネジを緩めて、不正防止プレート17を外側へスライドさせることによって、係合片8,8の設置位置近辺において、外枠2と隣のパチンコ機のカードリーダ装置(あるいは球貸装置)との間にスペースが生じる事態を防止できる。
【0015】
パチンコ機1は、上記の如く、鉤部材10a,10bを係合片8,8に係合させた場合に、鉤部材10a,10bの係合片8,8との係合側の表面に対峙する不正防止カバー15,15が設けられており、左側にカードリーダ装置(あるいは球貸装置)25を付設した状態で、パチンコホールの島設備に設置した後に、上方から「こじ開け器具」を外枠2と隣のパチンコ機のカードリーダ装置(あるいは球貸装置)との隙間に挿入させても、不正防止カバー15,15が障害物となり、「こじ開け器具」の先端で鉤部材10a,10bを押し下げることができないため、「ミドル枠こじ開け不正」を効果的に防止することができる。また、不正防止カバー15,15が、係合片8,8に一体的に設けられているため、構造が頑丈であり、ミドル枠3の開閉が頻繁に繰り返された場合でも、簡単に損傷したりしない。また、不正防止カバー15,15を係合片8,8と別個に設けられたものに比べて、安価かつ容易に製造することができる。
【0016】
さらに、パチンコ機1は、外枠2の左右の後端縁(係合片8,8に係合されたミドル枠3の鉤部材10a,10bと同じ高さの部位)に、外側にスライド突出自在で任意の位置で固定可能な不正防止プレート17,17が設けられており、左側にカードリーダ装置(あるいは球貸装置)25を付設した状態でパチンコホールの島設備に設置する際に、島設備上の関係で、外枠2と隣のパチンコ機のカードリーダ装置(あるいは球貸装置)との間隔が若干広くなってしまう場合でも、係合片8,8を外枠2に螺着しているネジを緩めて、不正防止プレート17,17を外側へスライドさせることによって、係合片8,8の設置位置近辺において、外枠2と隣のパチンコ機のカードリーダ装置(あるいは球貸装置)との間にスペースが生じる事態を防止できるので、「ミドル枠こじ開け不正」をより万全に防止することができる。加えて、不正防止プレート17,17が、長孔26,26部分を外枠2に螺着したものであるため、ネジを緩めるだけで、容易に突出量を調節できる。
【0017】
なお、本発明の遊技機の構成は、上記した各実施例の態様に何ら限定されるものではなく、外枠、ミドル枠、前面枠、上皿部、下側機能部、施錠機構、係合片、不正防止カバー、不正防止プレート等の形状・構造等の構成を、本発明の趣旨を逸脱しない範囲で、必要に応じて適宜変更できる。
【0018】
たとえば、パチンコ機は、右側に施錠機構が設けられたものに限定されず、左側に施錠機構が設けられたものでも良い。また、施錠機構は、2つの鉤部材が連結部材の作動に伴って連動するものに限定されず、1つの鉤部材のみからなるものでも良いし、3つ以上の鉤部材が連動するものでも良い。さらに、別個独立に作動する複数の鉤部材を有するものでも良い。加えて、鉤部材は、上方に回動して係合片(係合部)と係合するものに限定されず、下方に回動して係合片と係合するものや、上下動して係合片と係合するものでも良い。また、連結部材を付勢する部材は、上記実施形態の如きコイルバネに限定されず、板バネ等の他の弾性部材を用いることができる。
【0019】
一方、不正防止カバーは、係合片に一体的に設けられたものに限定されず、別個独立に設けられたものでも良い。また、外枠に設けられたものに限定されず、ミドル枠(本体枠)に設けられたものでも良い。さらに、不正防止カバーは、上記実施形態の如く、係合片の係合部の上端から後方にかけて下向きに傾斜した帯状体(鉤部材の先端と同じ角度で傾斜しており、係合片(係合部)と係合した鉤部材の先端とフィットする帯状体)に限定されず、回動する鉤部材の先端の軌跡の後方に鉤部材と垂直に設けられた平板状の帯状体等、別の形状を有するものでも良い。なお、不正防止カバーを、係合片の係合部の上端から後方にかけて下向きに傾斜した帯状体とした場合には、不正防止カバーは、コンパクトである上、効果的に「ミドル枠こじ開け不正」を防止することができるものとなる。
【0020】
また、不正防止プレートは、長孔における螺着位置を変更することによって突出長さを調節できるものに限定されず、幅方向に複数のネジ孔が穿設されており螺着するネジ孔を変更することにより突出長さを調節できるもの等、別の突出量調節機構を有するものでも良い。さらに、不正防止プレートは、係合片と略同一な幅を有しており係合片に積層された状態で係合片とともに外枠の後端縁に設置されるものに限定されず、係合片の上下に位置するように外枠の後端縁に設置されるものや、係合片と別個に外枠の後端縁に設置されるもの、あるいは外枠の高さと略同一な幅を有しており外枠の右側あるいは左側の後端縁全体に亘って設置されるいるもの等でも良い。加えて、ミドル枠は、金属によって形成されたものに限定されず、合成樹脂等によって形成されたものでも良い。また、遊技盤や機構板と別個になったものに限定されず、遊技盤や機構板と一体となってものでも良いし、その他の部材が設置されたものでも良い。なお、本発明の遊技機は、パチンコ機ばかりでなく、スロットマシーン等の他の遊技機として応用することも可能である。
【0021】
【発明の効果】
本発明の遊技機は、外枠の後端縁に位置した係合片の螺着部に、外枠から外側に突出自在で任意の突出位置で固定可能な不正防止プレートを当接するように設けたものであり、左側にカードリーダ装置(あるいは球貸装置)を付設した状態でパチンコホールの島設備に設置する際に外枠と隣のパチンコ機のカードリーダ装置(あるいは球貸装置)との間隔が若干広くなってしまう場合でも、不正防止プレートを外側へスライド突出させることによって、係合片の設置位置近辺において、外枠と隣のパチンコ機のカードリーダ装置(あるいは球貸装置)との間にスペースが生じる事態を防止できるので、「ミドル枠こじ開け不正」をより万全に防止することができる。

Therefore, the connecting member 9 urged by the spring members 11 and 11 is lowered, and the flange members 10a and 10b are rotated so that the tip ends upward. When the engaging portions 14 and 14 of the engaging pieces 8 and 8 are engaged with the notches 16 of the flange members 10a and 10b, respectively, the middle frame 3 is closed with respect to the outer frame 2. Locked (see FIG. 4).
[0012]
In addition, when a key (not shown) suitable for the key hole 27 of the locking device 13 is inserted and rotated to a predetermined position, the cam 23 rotates, and the connecting member 9 moves along with the rotation of the cam 23. The spring members 11 and 11 are lifted against the urging force of the spring members 11 and 11, and the flange members 10 a and 10 b are rotated so that the tips are directed downward (see FIG. 6). For this reason, the engagement between the notches 16 and 16 of the flange members 10a and 10b and the engaging portions 14 and 14 of the engaging pieces 8 and 8 provided on the outer frame 2 is released, and the middle frame 3 is removed from the outer frame 2. It becomes possible to open the frame 2 one side.

Therefore, it is possible to effectively prevent “illegal opening of the middle frame”. Further, since the fraud prevention covers 15 and 15 are provided integrally with the engagement pieces 8 and 8, the structure is strong, and even when the middle frame 3 is frequently opened and closed, it is easily damaged. Do not do. Further, compared to the tamper-proof covers 15 and 15 provided separately from the engagement pieces 8 and 8, the fraud prevention covers 15 and 15 can be manufactured inexpensively and easily.
[0016]
Further, the pachinko machine 1 slides outward on the left and right rear end edges of the outer frame 2 (parts having the same height as the flange members 10a and 10b of the middle frame 3 engaged with the engaging pieces 8 and 8). There are tamper-proof plates 17 and 17 that can be freely fixed at any position, and when the island is installed in a pachinko hall island facility with a card reader device (or ball lending device) 25 on the left side, Even if the distance between the outer frame 2 and the card reader device (or ball lending device) of the adjacent pachinko machine becomes slightly wide due to equipment, the engagement pieces 8 and 8 are screwed to the outer frame 2. The card reader device (or the ball lending device) of the outer frame 2 and the adjacent pachinko machine is located in the vicinity of the installation position of the engagement pieces 8, 8 by loosening the screws and sliding the fraud prevention plates 17, 17 outward. ) When there is a space between Can be prevented, it is possible to prevent the "middle frame broken open unauthorized" more thorough. In addition, since the fraud prevention plates 17 and 17 are obtained by screwing the long holes 26 and 26 into the outer frame 2, the amount of protrusion can be easily adjusted simply by loosening the screws.
