Description

【0001】
【発明の属する技術分野】
本発明は、前面枠本体の前面に覆い部材を交換可能に取り付け、この覆い部材の内周面に成形されるレール案内部に外側ガイドレールを取り付け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】
しかしながら、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、ニューモデルに変更すべく遊技盤を新しい遊技盤と交換するも、外側ガイドレールは引き続き使用できる場合は、前記古い遊技盤から外側ガイドレールを外し再び新しい遊技盤面に取り付けることになるが、前記のように多くの釘部材を逐一抜いて外し、再び打ち込むことになるから、これら作業が非常に面倒となり、作業性が極めて悪いという課題がある。
【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が図られると共に外側ガイドレールを移し替える作業を省き遊技盤交換の作業性が向上され、更には、前面枠本体の簡素化を図り製作費が軽減できるように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、遊技盤が配置される前面枠本体と、前記前面枠本体の前面に前記遊技盤の遊技部を囲うようにして交換可能に取り付けられ内周面にレール案内部を成形した覆い部材と、始端部と終端部のみを前記覆い部材の所定位置に止着して前記レール案内部に取り付けられる外側ガイドレールと、を備えた構成からなる。
【0007】
前記覆い部材におけるレール案内部の始端側に、前記外側ガイドレールの始端側を固定するための固定板部を一体に成形することが好ましい。
【0008】
このように、前面枠側に、しかも、両端部のみを支着して、外側ガイドレールが取り付けられるので、その取付作業が簡単になり、引いては、外側ガイドレール等の誘導レールの煩雑な取付作業が軽減される。また、ニューモデルに変更するため古い遊技盤を新しい遊技盤と交換するに、古い外側ガイドレールを引き続き使用する場合は、この外側ガイドレールが覆い部材側に取り付けられているので、外側ガイドレールの交換作業をする必要がなく、遊技盤の交換のみで済むことから作業性が極めて良い。
【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、詳しくは後記する上部・側部覆い部材31,32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、前面枠本体2aの周縁には枠部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に供給されるパチンコ球を発射するための発射装置29が取り付けられる。
【0015】
前記前面枠本体2a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とがそれぞれ交換可能にしかも別個に取り付けられている。覆い部材であるこれら上部覆い部材31と側部覆い部材32は、共に合成樹脂製であって、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35a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35a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の裏側に、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6、図7に示すように、前記側部覆い部材32には、レール案内溝33の始端側の下方に外側ガイドレール15の始端部を止着して固定するための固定板部32bが一体に成形されている。そして、この固定板部32b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9、図10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ための正位置設置具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、前記前面枠本体2aの前面に上部覆い部材31と側部覆い部材32を取り付ける。そして、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7に示すように、始端部側の円筒部54aを固定板部32b裏側の突起43に嵌合し、その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、前記固定板部32b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を介して固定板部32b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8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9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、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て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。これにより、外側ガイドレール15は常に円滑な弧面が具現されるように設置され、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が成形される。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】
このように本発明は、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、例えばニューモデルに変更するため古い遊技盤5を新しい遊技盤と交換するに、外側ガイドレール15を引き続き使用する場合、この外側ガイドレール15が上部・側部覆い部材側31,32に取り付けられているので、外側ガイドレール15を交換する必要がなく遊技盤5の交換のみで済むことから、極めて作業性が良い。
【0029】
本実施の形態にあっては、合成樹脂製の前面枠本体2aや覆い部材について説明したが、これに限られるものではなく、例えば金属製であっても良い。また、上部覆い部材31と側部覆い部材32をそれぞれ別々に成形したが、一体に成形するようにしてもよい。
【0030】
【発明の効果】
以上説明したように本発明の弾球遊技機は、合成樹脂製の前面枠本体の前面に、レール案内部を成形した合成樹脂製の覆い部材を交換可能に取付け、両端部のみを覆い部材に支着して前記レール案内部に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であって、引いては、誘導レールの煩雑な取付作業が軽減される。
【0031】
また、ニューモデルに変更するため古い遊技盤を新しい遊技盤と交換するに、古い外側ガイドレールを引き続き使用する場合は、この外側ガイドレールが覆い部材側に取り付けられているので、外側ガイドレールの交換作業をする必要がなく、遊技盤の交換のみで済むことから作業性が極めて良い。
【0032】
更に、特に上部覆い部材と側部覆い部材とを前面枠本体とは別個に成形して交換可能に設けるようにしているので、両覆い部材が前面枠本体に一体に成形されている場合に比較し、その構成が簡素化され、前面枠本体の製作費が安価になる。特に、前面枠本体が合成樹脂材により成形されるものであれば、金型費用が安価になる。しかも、前記上部覆い部材または側部覆い部材が破損などにより交換する必要が生じた場合でも、その破損した覆い部材のみを交換すれば済み、前面枠全体を交換する必要がないことから、無駄が少なく経済的であるという効果がある。

JP-A-2000-140239 (page 2-3, FIG. 2)
[0004]
[Problems to be solved by the invention]
However, 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 thereof, the mounting operation is performed. Is complicated. Also, even if the game board is replaced with a new game board in order to change to the new model, if the outer guide rail can be used continuously, the outer guide rail will be removed from the old game board and will be attached to the new game board surface again, As described above, since many nail members are pulled out and removed one by one and driven again, there is a problem that these operations are very troublesome and workability is extremely poor.
[0005]
In view of the above, the present invention has been made in view of the above-described problems, and the complicated installation work of the guide rail is reduced, and the work of transferring the outer guide rail is omitted, and the workability of the game board replacement is improved. It is an object of the present invention to provide a ball-and-ball game machine in which the front frame body is simplified so that manufacturing costs can be reduced.

[Means for Solving the Problems]
In order to achieve such an object, the ball-and-ball game machine according to the present invention is exchangeably attached to a front frame main body on which a game board is arranged, and to surround a game section of the game board on a front surface of the front frame main body. And a cover member having a rail guide portion formed on the inner peripheral surface thereof, and an outer guide rail attached to the rail guide portion by fixing only the start end and the end to predetermined positions of the cover member. Become.
[0007]
It is preferable that a fixing plate portion for fixing the start end side of the outer guide rail is integrally formed with the start end side of the rail guide portion in the cover member.
[0008]
As described above, since the outer guide rails are attached to the front frame side, and only the both ends are attached, the attachment work is simplified, and the complicated installation of the guide rails such as the outer guide rails is facilitated. Work is reduced. Also, when replacing the old game board with the new game board to change to the new model, if you want to continue using the old outer guide rail, since this outer guide rail is attached to the cover member side, The workability is extremely good since there is no need to carry out replacement work and only the replacement of the game board is required.
[0009]

The center of the shaft tube portion 48a is shifted from the center of the overhang plate portion 48b toward the terminal bent portion 44, and the shaft tube portion 48a is located at an eccentric position of the overhang plate portion 48b. Then, by rotating the normal position installation tool 47 to one side, the outer peripheral surface 63 of the overhang plate portion 48b gradually approaches (finally comes into pressure contact with) the end bent portion 44 side. .
[0020]
The screw 50 of the shaft cylinder portion 48a is tightened relatively strongly so that the normal position installation tool 47 does not turn unless it is turned with a fingertip, and one locking tooth 53a is provided on the inner surface of the operation portion 51. A plurality of locking teeth 53b, which can mesh with the locking teeth 53a, are provided on the back surface of the upper cover member 31 opposed thereto in an arc shape centering on the shaft tube portion 48a. When the knob 52 is pinched by the fingertip and the correct position setting tool 47 is rotated and stopped at an appropriate position, the locking teeth 53a and 53b mesh with each other, and the correct position setting tool 47 stops. .
[0021]
The outer guide rail 15 has a cylindrical portion 54a that is bent outward in a V-shape and fitted to the protrusion 43 at the distal end. The end portion is also bent outward in a V-shape to form a bent piece portion 55 attached to the end bent portion 44, and a cylindrical portion 54b fitted to the upper projection 43 is provided at the tip thereof. I have. A notch 56 is provided at one side edge of the outer guide rail 15 so that the claw portion 40 of the detachment preventing piece 41 can be engaged.
[0022]
According to the present invention, the upper cover member 31 and the side cover member 32 are attached to the front surface of the front frame body 2a. Then, the outer guide rail 15 is aligned with the rail guide groove 33, and as shown in FIG. 7, the cylindrical portion 54a on the starting end side is fitted into the projection 43 on the back side of the fixing plate 32b, and A screw 57 having a flange 57a having an outer diameter larger than that of the portion 54a is screwed into the screw hole 42. As a result, the cylindrical portion 54a is firmly fixed without coming off from the projection 43. A fixing member 58 is screwed on the front side of the fixing plate portion 32b. The fixing member 58 has a substantially right-angled triangular shape, and a pressing surface portion 59 that is parallel to the upper surface 39a of the supporting step portion 39 is provided on the upper edge of the back side of the substrate portion 58a. Then, the screws 62 are screwed into the screw holes 61 provided in the fixed plate portion 32b through the screw insertion holes 60 formed in the substrate portion 58a, so that the outer guide rails 15 mounted on the upper surface 39a of the supporting step portion 39 are screwed. Can be firmly fixed by the upper surface 39a and the pressing surface portion 59.
[0023]
Similarly, although not shown, the cylindrical portion 54b on the terminal end side 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. 8, 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. 9 so that the outer peripheral surface 63 is brought into contact with the surface of the bent piece portion 55. Crimp. As a result, 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, so that the outer guide rail 15 is compressed from both ends. The distance between them is reduced, and the outer guide rail 15 is accordingly bent toward the rail guide groove 33. Then, the back surface is pressed against the inner surface of the rail guide groove 33 to be stabilized. As a result, the outer guide rail 15 is installed so as to always realize a smooth arc surface, and 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]
As described above, according to the present invention, since the outer guide rails 15 are attached to the front frame 2 and only at both ends thereof, the attaching work is simplified. Further, when the outer guide rails 15 are to be continuously used to replace the old game board 5 with a new game board, for example, to change to a new model, the outer guide rail 15 is attached to the upper / side cover member sides 31, 32. Since the outer guide rails 15 do not need to be replaced and only the game board 5 needs to be replaced, the workability is extremely good.
[0029]
In the present embodiment, the front frame main body 2a and the cover member made of synthetic resin have been described. However, the present invention is not limited to this, and may be made of metal, for example. Further, although the upper cover member 31 and the side cover member 32 are formed separately, they may be formed integrally.
[0030]
【The invention's effect】
As described above, in the ball game machine of the present invention, a synthetic resin cover member formed with a rail guide portion is replaceably attached to the front surface of a synthetic resin front frame main body, and only both end portions are used as cover members. Since the outer guide rail is mounted on the rail guide portion by being attached, the mounting operation is simple, and the complicated mounting operation of the guide rail is reduced.
[0031]
Also, when replacing the old game board with the new game board to change to the new model, if you want to continue using the old outer guide rail, since this outer guide rail is attached to the cover member side, The workability is extremely good because there is no need to perform replacement work and only the replacement of the game board is required.
[0032]
Further, since the upper cover member and the side cover member are formed separately from the front frame main body so as to be replaceable, compared with a case where both cover members are integrally formed with the front frame main body. However, the structure is simplified, and the manufacturing cost of the front frame body is reduced. In particular, if the front frame body is formed of a synthetic resin material, the cost of the mold is reduced. Moreover, even when the upper cover member or the side cover member needs to be replaced due to damage or the like, only the damaged cover member needs to be replaced, and it is not necessary to replace the entire front frame. It has the effect of being less economical.
