Description

【0001】
【発明の属する技術分野】
本発明は、前面枠の窓開口の内周面に成形したレール案内部に外側ガイドレールが簡単に取り付けられ、かつ、外側ガイドレールが常に安定した球飛び状態を保持して配置できるようにした弾球遊技機に関するものである。
【0002】
【従来の技術】
従来、弾球遊技機の一種であるパチンコ遊技機は、例えば、前面枠に装着される遊技盤の前面に遊技部を囲むようにして誘導レールである内側ガイドレールと外側ガイドレールが渦巻き状に配設されている。これら内側・外側ガイドレールはいずれもその長手方向に沿って一定間隔置きに設けられた釘部材を直接打ち込むことにより遊技盤面に固定するようにしている(例えば、特許文献1参照。)。
【0003】
【特許文献1】
特開2000−140239号公報 (第2−3頁、図2)
【0004】
【発明が解決しようとする課題】
前記パチンコ遊技機にあっては、遊技盤面に内側・外側ガイドレールがいずれもその長手方向に沿って一定間隔置きに設けられた釘部材を直接打ち込むことにより固定されるので、その取付作業が煩雑である。また、特に外側ガイドレールは打球の球飛び状態を大きく左右させる関係上重要な要素を占める。ところが、前記のように一定間隔置きに設けられた釘部材により外側ガイドレールを固定すると、それら部分で外側ガイドレールが折れ曲がり、極論すれば多角形状に配設されることとなって、打球が跳ねるなど球飛び状態が極めて不安定になるばかりか、跳ねた打球がその前面を覆う透明板保持枠のガラス板を破損させてしまうといった課題がある。よって、前記外側ガイドレールが、できれば円滑な弧面となるようにして配置することが一番望ましい。
【0005】
そこで、本発明は上記課題に鑑みてなされたもので、誘導レールの煩雑な取付作業の軽減を図ると共に外側ガイドレールを常に円滑な弧面が具現されるようにして設置することにより安定した球飛び状態を保持した弾球遊技機を提供することを目的とするものである。
【0006】
【課題を解決するための手段】
かかる目的を達成するため、本発明に係る弾球遊技機は、遊技盤の遊技部が臨む窓開口を有し、前記窓開口の内周面に弧状のレール案内部を成形した前面枠と、両端部のみを前記前面枠の所定位置に止着して前記レール案内部に取り付けることにより前記遊技盤の前面に配置される外側ガイドレールと、を備え、前記外側ガイドレールのいずれか一端部は、外側へ折れ曲る折曲片部を介して止着され、その近傍に前記折曲片部を前記一端部を中心として他端部側へ回動させ外側ガイドレールをレール案内部に圧接する正位置設置手段を設けた構成からなる。
【0007】
前記正位置設置手段としては、例えば、前記前面枠に回動自在に軸支され、その回動動作に伴い外周面が前記折曲片部の表面を押圧して該折曲片部を回動させる正位置設置具がある。なお、この正位置設置手段は、これに限られるものではなく他の手段を採用しても良い。
【0008】
このように、前面枠側に、しかも、両端部のみを支着して、外側ガイドレールを取り付けるようにしたので、その取付作業が簡単になる。引いては、誘導レールの煩雑な取付作業が軽減される。また、外側ガイドレールをレール案内部に圧接する正位置設置手段を設けたので、外側ガイドレールを常に円滑な弧面が具現されるようにして設置することができ、球飛び状態が安定する。具体的には、正位置設置具を回動させることにより、その外周面を前記折曲片部の表面に押圧する。これにより、折曲片部側が他端部側へ押されるので、外側ガイドレールが両端部側から圧縮され、これに伴い外側ガイドレールがレール案内部側へ撓んで、その裏面がレール案内部内面に圧接して安定化する。
【0009】
【発明の実施の形態】
以下、本発明に係る弾球遊技機の実施の形態を図面に基づき説明する。なお、弾球遊技機には、例えばパチンコ遊技機、アレンジボール機または雀球遊技機があるが、本発明にあっては、一例としてパチンコ遊技機について説明する。図1は本発明が適用されるパチンコ遊技機の正面図、図2は前面枠の正面図、図3は同分解斜視図である。図において、1はパチンコ遊技機Pの機枠であって縦長方形枠状に成形されており、その前面に額縁状の前面枠2がその一側上下部を前記機枠1の一側上下部に設けた軸支部3,3によって軸支され、回動自在に装着されている。この前面枠2の上部中央には、窓開口4が開設されている。前面枠2の裏面には遊技盤5が配置され、その前面の遊技部5aが前記窓開口4に臨むようになっている。
【0010】
前記前面枠2の前面には、遊技盤5前面の遊技部5aを覆い2枚の透明板であるガラス板6を備えた透明板保持枠7及び遊技盤5の下部を覆う前面板8とが、いずれもその一側上下部を前面枠2の一側上下間に所定の間隔離して設けた複数の軸支部9に軸支され、回動自在に装着されている。前記前面板8の前面に、貯留される弾球であるパチンコ球を後記する打球発射部Aに供給するための打球供給皿10が装着されている。また、前記前面枠2の下部にも下部前板11が回動自在に装着され、この下部前板11の前面には、前記打球供給皿10から溢れるパチンコ球を貯留する下部球受皿12が装着されている。13は、下部前板11の前面一側に設けられ、打ち出されるパチンコ球の打球力の強弱を調節する操作ハンドルである。
【0011】
前記遊技盤5の前面に遊技部5aを囲う内側ガイドレール14が取り付けられ、前記前面枠2の窓開口4の内周面に外側ガイドレール15が取り付けられる。これら誘導レールとしての内側・外側ガイドレール14,15は、ステンレス製の金属帯板からなり、遊技盤5の前面に渦巻き状に配設される。内側ガイドレール14と外側ガイドレール15との間には、球飛走通路16が成形されると共にその内側ガイドレール14の終端位置に前記遊技部5aと連なる球放出口17が成形される。
【0012】
前記遊技部5aには、そのほぼ中央に表示部18aを備えた表示装置18が装着され、その下方にパチンコ球の入賞により前記表示部18aの文字、数字、図形等の表示を変動表示させる始動入賞口19が配設される。更に、その下方に、前記変動した表示が一定の時間経過後に停止して特定の表示(例えば「777」)を示し、遊技者にとって有利な特別遊技状態になったとき、一定の条件の下で開閉扉20aを所定回数開成させ一度に多くの入賞球が得られる入賞装置20が配設されている。前記始動入賞口19は、パチンコ球が入賞し難い起立またはパチンコ球が入賞し易い傾動位置に自在に変換可能な一対の可動翼片19a,19aを有している。
【0013】
更に、前記表示装置18の両側やや下方位置に一般入賞口21が配設され、これら一般入賞口21の上方位置にはパチンコ球が通過することによりそれを検知し、前記始動入賞口19の一対の可動翼片19a,19aをパチンコ球が受入れ易いように傾動させるための通過チャッカー22が配設されている。23は、前記遊技部5aの適宜位置に回転自在に装着され流下するパチンコ球の流れを変えて面白みを出させるための風車であり、24は障害釘である。更にまた、遊技部5aの下部には、遊技部5aを流下して前記始動入賞口19、一般入賞口21などに入賞しなかったパチンコ球をアウト球として遊技盤5の後方へ回収するアウト球口25が開設されている。
【0014】
前記前面枠2は、合成樹脂製であって縦長方形状に成形され、周縁には枠部26が設けられると共にその内側に基板部27が張設されている。そして、この基板部27に前記窓開口4が開設されることとなる。前記基板部27の前面下部には、その平坦な取付面Eに発射レール28と該発射レール28の打球発射部Aに供給するパチンコ球を発射させるための発射装置29が取り付けられる。
【0015】
前記前面枠2の裏面には、図4に示すように窓開口4を囲うようにして方形枠状の取付枠部30が一体に設けられ、下部の棚部30a上面に遊技盤5を載置して嵌め込むようになっている。なお、遊技盤5は取付枠部30から脱落しないように固定具(図示せず。)により、しっかりと固定されることになる。
【0016】
前記窓開口4には、前記前面枠2の一部を構成しその上部を覆う上部覆い部材31とその一側を覆う側部覆い部材32とが交換可能に取り付けられている。上部覆い部材31と側部覆い部材32は、共に合成樹脂材により成形され、窓開口4の内周面となる内側下面や内側側面にそれぞれ前記外側ガイドレール15を取り付けるためのレール案内部としてのレール案内溝33が成形される。また、上部覆い部材31と側部覆い部材32は、これら裏側の周縁と内側面に後方へ突出するリブ34が設けられ、周縁部の内面に沿って前記窓開口4の内周縁の所定個所に設けた突片36の螺子挿通孔37と対応位置する螺子孔(図示せず。)を設けたボス35が設けられている。そして、前記上部覆い部材31や側部覆い部材32は、前側から前記窓開口4の所定位置に配置され、各螺子挿通孔37を介して螺子孔に螺子38を螺入させることにより、図2に示すように上部覆い部材31と側部覆い部材32とがそれぞれ窓開口4の前面上部と前面一側部に装着される。
【0017】
前記各レール案内溝33は、図3に示すように上部・側部覆い部材31,32における前端縁の弧状縁部31a,32aの裏面に、該弧状縁部31a,32aに沿って成形される。このレール案内溝33には、図5に示すようにその前側縁部の長手方向に沿って、外側ガイドレール15のレール幅の約3分の1の幅を有し、かつ、レール案内溝33の底壁33a面よりも突出する弧状の支持段部39が成形されている。また、前記上部覆い部材31と側部覆い部材32とは連続せず分離して設けられており、上部覆い部材31の一側下端と側部覆い部材32の上端との間に所定幅の曲率調整空間Mが成形される。これにより、前記レール案内溝33及び支持段部39も長手方向における略中間位置で切除されることとなる。前記曲率調整空間Mに対応する基板部27の内側端縁に、内側へ突設され先端に外側ガイドレール15に係合し得る爪部40を設けた外れ防止片41が一体に設けられている。
【0018】
図5、図6に示すように、前記レール案内溝33の始端側に側部覆い部材32の裏面に位置して螺子孔42を有する突起43が突設されている。また、図8、図9に示すように、レール案内溝33の終端部は上方へ折り曲げられて一定の長さの終端折曲部44が設けられている。そして、その側方近傍とやや上方位置であって上部覆い部材31の裏面に螺子孔45を有する支持突起46と前記螺子孔42を有する突起43が突設されている。そして、前記終端折曲部44近傍の支持突起46に、前記外側ガイドレール15のレール案内溝33に対する緩みを無くし該外側ガイドレール15を正位置に設置する正位置設置手段としての正位置設置具47が装着される。
【0019】
前記正位置設置具47は、前記支持突起46に嵌合して該支持突起46を中心として回動し、後端面が閉塞する円筒状の軸筒部48aと、該軸筒部48aの外周面に張設され上部覆い部材31の裏面とほぼ平行に配置される張出板部48bと、からなる。軸筒部48aの後端面には、前記螺子孔45と連通する螺子挿通孔49が開設され、この螺子挿通孔49を介して螺子孔45に螺子50を螺合することにより正位置設置具47が軸着される。前記張出板部48bはほぼ円板状に成形され一側に外側へ突出する操作部51が設けられると共にその一側面に指先で摘んで操作できる摘み片部52が設けられている。軸筒部48aの中心は張出板部48bの中心より終端折曲部44側へずれており、軸筒部48aが張出板部48bの偏心位置にある。そして、正位置設置具47を一方へ回動させることにより、張出板部48bの外周面63が漸次終端折曲部44側に接近(最終的には圧接する。)するようになっている。
【0020】
前記軸筒部48aの螺子50は、指先で回さないと正位置設置具47が回動しない程度に比較的強く締められ、しかも、前記操作部51の内面に一つの係止歯53aが設けられ、これと対向する上部覆い部材31裏面に前記係止歯53aと互いに噛合し得る複数の係止歯53bが軸筒部48aを中心とする円弧状に設けられている。そして、指先で摘み片部52を摘み正位置設置具47を回動させ適宜位置で止めると、各係止歯53a,53bが互いに噛合して正位置設置具47が停止するようになっている。
【0021】
前記外側ガイドレール15は、始端部が外側へV字状に屈曲されると共にその先端に前記突起43に嵌合する円筒部54aが設けられる。終端部も同じく外側へV字状に屈曲されて前記終端折曲部44に添わせる折曲片部55が成形され、その先端に前記上方の突起43に嵌合する円筒部54bが設けられている。また、外側ガイドレール15の一側端縁に、前記外れ防止片41の爪部40が係合し得る切欠56が設けられている。
【0022】
本発明は上記構成からなり、前記外側ガイドレール15を前記レール案内溝33に沿わせ、図6に示すように、始端部側の円筒部54aを側部覆い部材32a側の突起43に嵌合し、裏側から前記円筒部54aより大きい外径の鍔57aを有する螺子57を螺子孔42に螺合する。これにより、円筒部54aが突起43から抜けることなくしっかりと固定される。また、前記レール案内溝33の始端部の前面側には固定部材58が螺着される。この固定部材58は、略直角三角形状をなし、基板部58a裏側の上縁部に前記支持段部39の上面39aと平行になる押え面部59が設けられている。そして、基板部58aに開設された螺子挿通孔60を介して側部覆い部材32に設けられた螺子孔61に螺子62を螺締することにより、支持段部39の上面39aに載る外側ガイドレール15の前側縁側をその上面39aと押え面部59とでしっかりと固定できることになる。
【0023】
同様に、図示は省略するが、前記外側ガイドレール15の終端部側の円筒部54bを上部覆い部材31側の突起43に嵌合し、裏側から前記と同じ螺子57を螺子孔42に螺合する。この際、折曲片部55が、終端折曲部44と正位置設置具47との間に位置し、しかも、折曲片部55と終端折曲部44との間には少しの隙間が成形されるようになっている。また、図7に示すように前記切欠56に外れ防止片41の爪部40が係合する。このように切欠56に外れ防止片41を係合させておくのは、外側ガイドレール15を前記レール案内溝33に取り付ける場合、両端部のみを前面枠2に止着する構造であり、しかも、外側ガイドレール15が弧状に湾曲していることから、遊技盤5を装着するまでの間に両端部を支点として後方へ回転してレール案内溝33から抜け出てしまうことがあり、このような事態を回避するためである。
【0024】
更にこの状態で、指先で摘み片部52を摘み、正位置設置具47を図8の矢視方向(反時計方向)へ回動させ、その外周面63を前記折曲片部55の表面に圧接する。これにより、図10、図11に示すように折曲片部55が外側ガイドレール15の他端部側へ押され折曲片部55がほとんど終端折曲部44に密接するので、外側ガイドレール15が両端部側から圧縮されその間の距離が縮まることとなり、これに伴い外側ガイドレール15がレール案内溝33側へ撓む。そして、その裏面がレール案内溝33内面に圧接して安定化する。また、前面枠2側に、しかも、両端部のみを支着して、外側ガイドレール15が取り付けられるので、その取付作業が簡単になる。さらに、外側ガイドレール15はレール案内溝33に圧接され、常に円滑な弧面が具現されるように設置されるので、球飛び状態が安定する。
【0025】
これにより、外側ガイドレール15がレール案内溝33の弧状縁部31a,32aと遊技盤5の前面との間に挟まれて取り付けられる。また、外側ガイドレール15は、一旦発射されるも飛走力が弱い等の理由により戻ってくるパチンコ球を下部球受皿12に導くための戻り球排出口64を介して前記発射レール28の先端部と連なることとなる。
【0026】
また、外側ガイドレール15は、底壁33aの裏面で支持され、しかも、その前縁側のみが前記支持段部39に当接して支持されることとなる。一方、支持されない部分は、その裏面に前記始端部と終端部との間の全体に亘りレール幅方向の少なくとも中央部に沿って空間Sが形成される。これにより、外側ガイドレール15に、所要の弾力性が付与されることとなり、飛走するパチンコ球は、特に発射レール28から飛び出して外側ガイドレール15の表面に着地するときもその衝撃が吸収され、飛走中にパチンコ球が無用に跳ね返ることを押え、これによっても球飛び状態が極めて良好となる。
【0027】
更に、前記上部覆い部材31と側部覆い部材32との間に曲率調整空間Mを形成しているが、通常、上部覆い部材31と側部覆い部材32との内周面、すなわちレール案内溝33、の曲率半径は異なっている。よって、製作された段階で一定の曲率半径に設定された外側ガイドレール15をレール案内溝33に取り付けたとき、外側ガイドレール15の上部側と下部側とで曲率半径が異なることから、歪みが生じてその表面がうねり、結果、球飛び状態が安定しなくなる。そこで、前記歪みを自由に湾曲できる曲率調整空間M内で逃すことによって、外側ガイドレール15の表面を滑らかな面とし、安定した球飛び状態を確保しようとするものである。
【0028】
本発明にあっては、前記したように、外側ガイドレールの終端側に正位置設置手段を設けたが、その始端側に設けるようにしても良く、また、正位置設置手段も他の手段を用いるようにしてもよいこと勿論である。
【0029】
【発明の効果】
以上説明したように本発明の弾球遊技機は、両端部のみを所定位置に止着して前面枠のレール案内部に外側ガイドレールを取り付け、前記外側ガイドレールのいずれか一端部は、外側へ折れ曲る折曲片部を介して止着され、その近傍に前記折曲片部を前記一端部を中心として他端部側へ回動させ外側ガイドレールをレール案内部に圧接する正位置設置手段を設けた構成からなるので、その取付作業が簡単に行えることとなり、これにより誘導レールの煩雑な取付作業の軽減が図られる。また、外側ガイドレールを常に円滑な弧面が具現されるようにして設置することができりことから、球飛び状態が極めて安定し、例えば、発射されたパチンコ球が飛走の途中で跳ねて透明板保持枠のガラス板を破損させるなどして遊技の興趣が殺がれるといったこともないという効果がある。

TECHNICAL FIELD OF THE INVENTION
According to the present invention, the outer guide rail can be easily attached to the rail guide formed on the inner peripheral surface of the window opening of the front frame, and the outer guide rail can always be arranged while maintaining a stable ball flying state. It relates to a ball-and-ball game machine.
[0002]
[Prior art]
Conventionally, a pachinko gaming machine, which is a type of ball-and-ball gaming machine, has, for example, an inner guide rail and an outer guide rail, which are guide rails, arranged in a spiral shape on a front surface of a game board mounted on a front frame so as to surround a game section. Have been. Both the inner and outer guide rails are fixed to the game board surface by directly driving nail members provided at regular intervals along the longitudinal direction (for example, see Patent Document 1).
[0003]
[Patent Document 1]
JP-A-2000-140239 (page 2-3, FIG. 2)
[0004]
[Problems to be solved by the invention]
In the pachinko gaming machine, since the inside and outside guide rails are fixed on the game board surface by directly driving nail members provided at regular intervals along the longitudinal direction, the mounting operation is complicated. It is. In particular, the outer guide rail occupies an important element in relation to greatly affecting the ball flying state of the hit ball. However, when the outer guide rails are fixed by the nail members provided at regular intervals as described above, the outer guide rails are bent at those portions, and in extreme cases, the outer guide rails are arranged in a polygonal shape, and the hit ball jumps. In addition to the extremely unstable ball flying state, there is a problem that the hit ball may damage the glass plate of the transparent plate holding frame covering the front surface thereof. Therefore, it is most desirable to arrange the outer guide rails so as to have a smooth arc surface if possible.
[0005]
Therefore, the present invention has been made in view of the above-mentioned problems, and aims to reduce the complicated mounting work of the guide rail and to provide a stable ball by installing the outer guide rail so as to always realize a smooth arc surface. It is an object of the present invention to provide a ball game machine which keeps a flying state.
[0006]
[Means for Solving the Problems]
In order to achieve such an object, the ball game machine according to the present invention has a window opening facing a game unit of a game board, and a front frame in which an arc-shaped rail guide is formed on an inner peripheral surface of the window opening. An outer guide rail arranged on the front surface of the game board by fixing only both end portions to a predetermined position of the front frame and attaching to the rail guide portion, and one end of the outer guide rail is Is fastened to the outer guide rail by pressing the outer guide rail to the rail guide portion by rotating the bent piece portion to the other end side around the one end portion. It has a configuration provided with a normal position setting means.
[0007]
The normal position setting means is, for example, rotatably supported by the front frame, and an outer peripheral surface thereof presses the surface of the bent piece portion to rotate the bent piece portion with the rotation operation. There is a position setting tool to make it. Note that the normal position setting means is not limited to this, and other means may be employed.
[0008]
As described above, since the outer guide rail is attached to the front frame side, and only the both ends are attached, the attaching operation is simplified. As a result, complicated installation work of the guide rail is reduced. In addition, since the normal position setting means for pressing the outer guide rail against the rail guide portion is provided, the outer guide rail can be set so as to always realize a smooth arc surface, and the ball flying state is stabilized. Specifically, the outer peripheral surface is pressed against the surface of the bent piece part by rotating the normal position installation tool. As a result, the bent piece portion is pushed toward the other end, so that the outer guide rail is compressed from both end portions, whereby the outer guide rail bends toward the rail guide portion, and the back surface is the inner surface of the rail guide portion. Pressed against to stabilize.
[0009]

[0023]
Similarly, although not shown, the cylindrical portion 54b at the end of the outer guide rail 15 is fitted into the projection 43 on the upper cover member 31, and the same screw 57 is screwed into the screw hole 42 from the back side. I do. At this time, the bent piece portion 55 is located between the terminal bent portion 44 and the normal position setting tool 47, and a slight gap is formed between the bent piece portion 55 and the terminal bent portion 44. It is designed to be molded. Further, as shown in FIG. 7, the claw portion 40 of the detachment preventing piece 41 is engaged with the notch 56. In this manner, when the outer guide rail 15 is attached to the rail guide groove 33, only the both ends are fixed to the front frame 2 when the detachment preventing piece 41 is engaged with the notch 56. Since the outer guide rails 15 are curved in an arc shape, the outer guide rails 15 may rotate rearward with both ends serving as fulcrums and fall out of the rail guide grooves 33 until the game board 5 is mounted. It is to avoid.
[0024]
Further, in this state, the grip portion 52 is gripped with the fingertip, and the normal position setting tool 47 is rotated in the direction of the arrow (counterclockwise) in FIG. 8 so that the outer peripheral surface 63 is brought into contact with the surface of the bent piece portion 55. Crimp. As a result, as shown in FIGS. 10 and 11, the bent piece 55 is pushed toward the other end of the outer guide rail 15, and the bent piece 55 almost comes into close contact with the terminal bent part 44. The outer guide rail 15 is bent toward the rail guide groove 33 along with the compression of the outer guide rail 15 from both ends. Then, the back surface is pressed against the inner surface of the rail guide groove 33 to be stabilized. Further, since the outer guide rails 15 are attached to the front frame 2 side, and only the both ends are attached, the attaching work is simplified. Further, since the outer guide rail 15 is pressed against the rail guide groove 33 and is installed so as to always realize a smooth arc surface, the ball flying state is stabilized.
[0025]
As a result, the outer guide rail 15 is attached between the arcuate edges 31 a and 32 a of the rail guide groove 33 and the front surface of the game board 5. Further, the outer guide rail 15 is provided at the tip of the firing rail 28 via a return ball discharge port 64 for guiding a pachinko ball which is fired once but returns due to a weak flying force or the like to the lower ball tray 12. Department.
[0026]
Further, the outer guide rail 15 is supported on the back surface of the bottom wall 33a, and only the front edge side of the outer guide rail 15 comes into contact with and is supported by the supporting step portion 39. On the other hand, a space S is formed on the back surface of the unsupported portion along at least the central portion in the rail width direction over the entire area between the start end and the end. As a result, the required elasticity is imparted to the outer guide rail 15, and the impact of the flying pachinko ball is absorbed especially when the pachinko ball jumps out of the firing rail 28 and lands on the surface of the outer guide rail 15. This suppresses the useless bouncing of the pachinko ball during the flight, which also makes the ball fly very well.
[0027]
Further, a curvature adjusting space M is formed between the upper covering member 31 and the side covering member 32. Usually, an inner peripheral surface of the upper covering member 31 and the side covering member 32, that is, a rail guide groove is provided. 33 have different radii of curvature. Therefore, when the outer guide rail 15 having a fixed radius of curvature is attached to the rail guide groove 33 at the time of manufacture, the curvature is different between the upper side and the lower side of the outer guide rail 15 so that distortion is reduced. As a result, the surface swells, and as a result, the ball flying state becomes unstable. Then, the surface of the outer guide rail 15 is smoothed by releasing the distortion in the curvature adjusting space M that can freely bend, and a stable ball flying state is to be ensured.
[0028]
In the present invention, as described above, the correct position setting means is provided at the end side of the outer guide rail, but may be provided at the start end side, and the correct position setting means also includes other means. Of course, it may be used.
[0029]
【The invention's effect】
As described above, in the ball game machine of the present invention, only the both ends are fixed to the predetermined positions, and the outer guide rail is attached to the rail guide portion of the front frame. A right position where the outer guide rail is pivotally moved to the other end side around the one end portion in the vicinity thereof and is fixed to the rail guide portion by pressing the outer guide rail against the rail guide portion. Since the configuration is such that the installation means is provided, the mounting operation can be easily performed, thereby reducing the complicated mounting operation of the guide rail. Also, since the outer guide rail can always be installed so as to realize a smooth arc surface, the ball flying state is extremely stable, for example, when the launched pachinko ball jumps in the middle of the flight There is an effect that the interest of the game is not lost by breaking the glass plate of the transparent plate holding frame.
