Description

【０００１】
【発明の属する技術分野】
本発明は、パチンコ機、アレンジボール機、雀球遊技機等の弾球遊技機に関するものである。
【０００２】
【従来の技術】
パチンコ機等の弾球遊技機には、始動手段が遊技球を検出することを条件に図柄表示手段の１個又は複数個の図柄が所定時間変動して停止し、この変動後の停止図柄が予め定められた特定図柄（所謂大当たり図柄）のときに、利益状態発生手段による利益状態が発生して、可変入賞手段が遊技者に有利な第１状態と不利な第２状態とに変換動作するようにしたものがある。
【０００３】
可変入賞手段は所謂大入賞手段を構成するものであって、図柄表示手段の停止図柄が大当たり図柄のときに、開閉板が横軸廻りに前上がり状に回動して入賞口を開放し、遊技盤に沿って上方から落下する遊技球を開閉板により入賞口へと案内するようになっている。この可変入賞手段の入賞領域は、開閉板の左右幅で決まり、通常５５ｍｍ〜９０ｍｍの範囲で一定になっている。
【０００４】
【発明が解決しようとする課題】
可変入賞手段は、通常、開放後に所定時間経過するか、又は遊技球が１０個入賞した時に開閉板が閉じ、また開放中に入賞した遊技球が特定領域を通過することを条件に、所定回数、例えば最大１６回まで開閉動作を繰り返すようになっている。従って、利益状態発生手段による利益状態が発生すれば、可変入賞手段の開閉によって、遊技者は多大な利益の還元を受けることが可能である。
【０００５】
しかし、従来の弾球遊技機では、可変入賞手段の入賞領域が一定であって、ゲーム中に変化しないので、遊技者は利益状態の発生によって略一定の利益を獲得できるものの、変化に乏しく興趣に欠ける問題がある。
【０００６】
本発明は、このような従来の問題点に鑑み、利益状態の発生後のゲーム状態が変化し、遊技者の興趣を向上できる弾球遊技機を提供することを目的とする。
【０００７】
【課題を解決するための手段】
本発明は、遊技者に有利な第１状態と不利な第２状態とに変換動作可能な可変入賞手段１３と、始動手段１２と、該始動手段１２が遊技球を検出することを条件に所定時間変動して停止する１個又は複数個の図柄を表示する図柄表示手段１８と、該図柄表示手段１８の変動後の停止図柄が予め定められた特定図柄のときに利益状態を発生させる利益状態発生手段６５とを備え、前記利益状態発生手段６５による前記利益状態の発生中は所定条件を達成する都度前記可変入賞手段１３が前記第２状態から前記第１状態へと最大所定の複数回変換動作可能な弾球遊技機において、前記可変入賞手段１３は１個の入賞口２１と、該入賞口２１に対応して設けられ且つ第１状態のときに前記入賞口２１を開放して該入賞口２１へと遊技球を案内する複数個の開閉板２２〜２４とを備え、前記開閉板２２〜２４の開放数を変えて前記可変入賞手段１３の第１状態での入賞領域を変化させる入賞領域変化手段２５を備え、前記入賞領域変化手段２５は前記利益状態の発生中に前記所定条件を達成して前記可変入賞手段１３が前記第２状態から前記第１状態に変換動作する都度、前記開閉板２２〜２４の開放数を順次増やすように構成したものである。
【０００８】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づいて詳述する。図１〜図８は本発明の第１の実施形態を例示し、図１において、1 は遊技機本体で、開閉自在に枢着された前枠2 を有する。前枠2 には、その窓孔に対応して遊技盤3 が裏側から着脱自在に装着され、また遊技盤3 の前側にガラス扉4 と前面板5 とが開閉自在に配置されている。
【０００９】
前面板5 には、発射用の遊技球を貯留する上皿6 が装着されている。前枠2 の下部には、余剰球を貯留する下皿7 と、発射手段の発射ハンドル8 とが夫々設けられている。
【００１０】
遊技盤3 には、図２に示すように、ガイドレール9 が環状に装着されると共に、そのガイドレール9 の内側の遊技領域10に液晶表示手段11、第２始動手段12、可変入賞手段13、第１始動手段14、普通入賞手段15〜17等の複数個の遊技部品が配置されている。
【００１１】
液晶表示手段11は、第２図柄表示手段18を兼用している。第２図柄表示手段18は、その表示画面に１個又は複数個、例えば左右方向に３個の遊技図柄を表示し、第２始動手段12が遊技球を検出することを条件に、乱数制御により３個の遊技図柄が所定時間変動して停止するようになっている。なお、遊技図柄は数字図柄、アルファベット図柄、キャラクター図柄等により構成されており、この実施形態では数字図柄が使用されている。
【００１２】
第２始動手段12には、開閉自在な左右一対の開閉爪12a を備えた開閉入賞式の電動チューリップ等が使用されており、第１図柄表示手段19の変動後の停止図柄が所定図柄（当たり図柄）を表示したときに、開閉爪12a が所定時間開放するようになっている。
【００１３】
液晶表示手段11の上部に第１図柄表示手段19が設けられている。第１図柄表示手段19は１又は複数個、例えば１個の遊技図柄（数字図柄）を表示し、通過ゲート式等の第１始動手段14が遊技球を検出することを条件に、その遊技図柄が乱数制御により所定時間変動して停止するようになっている。
【００１４】
可変入賞手段13は所謂大入賞手段を構成するものであって、遊技者に有利な開状態（第１状態）と不利な閉状態（第２状態）とに変換動作すると共に、開状態での入賞領域が変化するように構成されており、第２図柄表示手段18の変動後の停止図柄が「７・７・７」等の特定図柄（大当たり図柄）の組み合わせとなる所謂大当たりのときに、第２状態から第１状態に変換動作を行い、その特定図柄の種類に応じてその入賞領域が複数段階（複数種類）に段階的に変化するようになっている。
【００１５】
可変入賞手段13は、図３〜図７に示すように、遊技盤3 の装着孔に嵌合する入賞ケース20と、この入賞ケース20の入賞口21を開閉する開閉板22〜24とを備え、入賞領域を変化させる入賞領域変化手段25が一体的に組み込まれている。
【００１６】
入賞ケース20は横長矩形状で、遊技盤3 の前面に当接する前飾り板26を有し、その前飾り板26の上部側の左右中央に入賞口21が横長矩形状に形成されている。
入賞ケース20の内部又は裏側は、左右方向に複数個、例えば３個に分割され、その一部が特定領域27となり、その他が通常の入賞通路28,29 となっている。入賞口21と特定領域27、入賞通路28,29 との間には、入賞口21に入賞した遊技球を特定領域27と入賞通路28,29 との何れかに案内するように案内板30が設けられている。
【００１７】
特定領域27は中央に、入賞通路28,29 はその両側に夫々配置され、これらは入賞ケース20の裏板20a に装着された通路ケース31内に形成されている。特定領域27には、この特定領域27を通過する遊技球を検出する特定領域検出スイッチ32が設けられ、またその下側に、特定領域27及び入賞通路28,29 を通過する遊技球、即ち入賞口21に入賞した遊技球を検出する計数スイッチ33が設けられている。
【００１８】
なお、案内板30には、特定領域27、入賞通路28,29 に対応して山形状等の案内部が前後方向に形成されている。特定領域27、入賞通路28,29 は、案内板30に下向きに形成しても良い。
【００１９】
開閉板22〜24は、例えば中央の主開閉板22と、その左右両側の副開閉板23,24 のように、左右方向に複数個、例えば３個に分割されており、この各開閉板22〜24は下部側の左右方向の横軸34により、入賞口21を閉鎖する閉状態と、前上がりに傾斜して遊技球を入賞口21へと案内する開状態との間で開閉自在に枢支されている。
【００２０】
横軸34は、各開閉板22〜24の下部側に挿通され、左右両端が前飾り板26の裏側の軸受部35により支持されている。なお、横軸34は、各開閉板22〜24に共通でも良いし、各開閉板22〜24毎に別々に設けても良い。
【００２１】
入賞領域変化手段25は、開閉板22〜24の左右幅により決定される入賞領域を複数段階に段階的に変化させるもので、３個の開閉板22〜24と、この開閉板22〜24を開閉駆動する駆動手段36〜38とにより構成されている。
【００２２】
即ち、入賞領域変化手段25は、例えば「０・０・０」〜「９・９・９」の１０種類の大当たり図柄の内、「３・３・３」及び「７・７・７」のときに開閉板22〜24が開放して入賞領域が広領域A1となり、「１・１・１」、「５・５・５」及び「９・９・９」のときに主開閉板22及び副開閉板24が開放して中領域A2となり、他の偶数図柄のときに主開閉板22が開放して狭領域A3となるように、大当たり図柄の種類に応じて可変入賞手段13の入賞領域を複数種類に変化させるように構成されている。
【００２３】
なお、主開閉板22には、この主開閉板22上に落下した遊技球を中央側へと案内する左右一対の案内突起39が設けられている。
【００２４】
主開閉板22は主駆動手段36により開閉可能であり、その主駆動手段36は、主開閉板22の後方の一端側で裏板20a の前側に上下方向に配置されたソレノイド40と、このソレノイド40の可動鉄心41の上端側に固定され且つ案内板30の下側で主開閉板22の作動アーム42に係合する係合体43と、係合体43を上向きに付勢するバネ44とを備え、ソレノイド40に通電したときに可動鉄心41がバネ44に抗して下降して主開閉板22を開状態から閉状態に駆動するようになっている。
【００２５】
左右の各副開閉板23,24 は副駆動手段37,38 により開閉可能であり、その副駆動手段37,38 は、副開閉板23,24 の後方で裏板20a の前側に上下方向に配置されたソレノイド45,46 と、このソレノイド45,46 の可動鉄心47,48 の上端側に固定され且つ副開閉板23,24 の作動アーム49,50 に係合する係合体51,52 と、係合体51,52 を上向きに付勢するバネ53,54 とを備え、ソレノイド45,46 に通電したときに可動鉄心47,48 がバネ53,54 に抗して下降して副開閉板23,24 を開状態から閉状態に駆動するようになっている。
【００２６】
各駆動手段36〜38は、係合体43が案内板30の下面を、係合体51,52 が突起55,56 を夫々ストッパーとして下側から当接し、非通電時に開閉板22〜24をバネ44,53,54の付勢力により開状態に保持するようになっている。なお、駆動手段36〜38は、通電時に開閉板22〜24を開放させるようにしても良い。また駆動手段36〜38は電動モータ等により構成しても良い。普通入賞手段16,17 は、可変入賞手段13の前飾り板26に設けられている。
【００２７】
なお、可変入賞手段13は、開閉板22〜24の開放から所定時間（例えば３０秒）が経過したとき、又は計数スイッチ33が所定数（例えば１０個）の遊技球の入賞を検出したときに開閉板22〜24を閉じると共に、遊技球が特定領域27を通過することを条件に、最大所定回数（例えば１６回）まで開閉動作を繰り返すようになっている。
【００２８】
遊技盤3 の前面側には、可変入賞手段13の入賞領域の変化を表示する入賞領域表示手段57が設けられている。即ち、入賞領域表示手段57は、可変入賞手段13の前面側、例えば入賞ケース20の前飾り板26における入賞口21の上側又は下側等の遊技者が確認し易い箇所に配置されており、横一列状に配置された複数個の表示ランプ58により構成されている。
【００２９】
複数個の表示ランプ58は、その１個又は複数個が各開閉板22〜24に対応しており、広領域A1のときに主開閉板22及び副開閉板23,24 に対応する表示ランプ58が、中領域A2のときに主開閉板22及び副開閉板24に対応する表示ランプ58が、狭領域A3のときに主開閉板22に対応する表示ランプ58が夫々点滅発光して表示するようになっている。なお、入賞領域表示手段57は、可変入賞手段13以外の箇所に設けても良いし、また文字等で入賞領域の広狭の変化を直接表示するようにしても良い。
【００３０】
図８は制御系を例示するブロック図である。59は第１乱数選択手段で、当たり・外れ決定用乱数を繰り返して発生し、第１始動手段14が遊技球を検出することを条件に、その時点の乱数を選択するようになっている。60は第１図柄表示制御手段で、第１始動手段14が遊技球を検出することを条件に第１図柄表示手段19の遊技図柄を所定時間変動させて、第１乱数選択手段59が選択した当たり乱数又は外れ乱数に応じて遊技図柄を当たり図柄又は外れ図柄で停止させるようになっている。
【００３１】
61は開閉制御手段で、第１図柄表示手段19の変動後の停止図柄が「７」等の当たり図柄で停止したときに、第２始動手段12の一対の開閉爪12a を所定時間開放させて、第２始動手段12に遊技球が入賞し易くなるように制御すべく構成されている。
【００３２】
62は第２乱数選択手段で、大当たり・外れ決定用乱数、変動パターン決定用乱数、停止図柄決定用乱数等の所定の乱数を繰り返して発生し、第２始動手段12が遊技球を検出することを条件にその乱数を選択するようになっている。なお、第２乱数選択手段62は、例えば第２図柄表示手段18の停止図柄が大当たり図柄となる大当たり発生確率が１／２５０の場合には、０〜２４９の大当たり・外れ決定用乱数等を発生する。
【００３３】
63は第２図柄表示制御手段で、第２始動手段12に遊技球が入賞することを条件に、第２乱数選択手段62で選択された大当たり・外れ決定用乱数、変動パターン決定用乱数、停止図柄決定用乱数等に応じて第２図柄表示手段18の各遊技図柄を所定時間変動させて停止させる機能を有し、例えば第２乱数選択手段62が大当たり乱数値を選択したときに、変動パターン決定用乱数により決定された変動パターンを経て、図柄乱数により決定された特定図柄の組み合わせ、例えば「７・７・７」等の停止図柄で遊技図柄を停止させるようになっている。
【００３４】
64は記憶手段で、第２図柄表示手段18の遊技図柄の変動中に、第２始動手段12に遊技球が入賞したとき、その入賞を所定数（例えば４個）まで記憶し、第２図柄表示手段18の変動動作が終了する毎に、その記憶個数分に応じて第２図柄表示手段18の遊技図柄を変動させるためのものである。
【００３５】
65は利益状態発生手段で、第２乱数選択手段62が大当たり乱数値を選択して第２図柄表示手段18の変動後の遊技図柄が特定図柄の組み合わせとなる大当たりのときに、可変入賞手段13を第２状態から第１状態に変換動作させて、遊技者に有利な特定利益状態を発生させるものである。
【００３６】
即ち、利益状態発生手段65は、第２始動手段12への遊技球の入賞時に第２乱数選択手段62により抽選された大当たり・外れ乱数及び／又は第２図柄表示手段18の変動後の停止図柄から大当たり、外れの判定を行い、第２図柄表示手段18の変動後における遊技図柄の停止図柄が「７・７・７」等の大当たり図柄となったときに、可変入賞手段13の開閉板22〜24を開放させて遊技者に有利な利益状態を発生させるようになっている。
【００３７】
利益状態発生手段65は、第２図柄表示手段18の変動後における停止図柄から大当たり、外れの別を判定して、遊技者に有利な利益状態を発生させるための大当たり判定部73と、第２図柄表示手段18の変動後における停止図柄が大当たり図柄となったときに可変入賞手段13の開閉板22〜24を開閉制御する開閉制御部66との他に、大当たり図柄の種類に応じて可変入賞手段13の入賞領域が複数段階に段階的に変化するように制御する入賞領域制御部67と、入賞領域表示手段57の表示を制御する入賞領域表示制御部68とを有する。
【００３８】
入賞領域制御部67には、大当たり図柄の種類に応じて可変入賞手段13の入賞領域が夫々設定されており、変動後の停止図柄が所定種類の大当たり図柄を表示するときに、可変入賞手段13の入賞領域をその大当たり図柄の種類に応じて変化させるべく開閉制御部66に制御信号を送るようになっている。
【００３９】
例えば、入賞領域制御部67は、「０・０・０」〜「９・９・９」の１０種類の大当たり図柄の内、「３・３・３」及び「７・７・７」のときに入賞領域変化手段25の駆動手段36〜38が作動して入賞領域が広領域A1となり、「１・１・１」、「５・５・５」及び「９・９・９」のときに駆動手段36,38 が作動して中領域A2となり、他の偶数図柄のときに駆動手段36が作動して狭小領域A3となるように、大当たり図柄の種類に応じて領域制御信号を開閉制御部66に送信する。
【００４０】
入賞領域表示制御部68は、「０・０・０」〜「９・９・９」の１０種類の大当たり図柄の内、「３・３・３」及び「７・７・７」のときに開閉板22〜24に対応する表示ランプ58を、「１・１・１」、「５・５・５」及び「９・９・９」のときに主開閉板22及び副開閉板24に対応する表示ランプ58を、他の図柄のときに主開閉板22に対応する表示ランプ58を夫々点滅発光させるようになっている。
【００４１】
なお、利益状態発生手段65は、開閉板22〜24の開放中に入賞した遊技球が特定領域27を通過することを条件に、所定回数（例えば最大１６回）まで開閉動作を継続させるようになっている。
【００４２】
次に上記弾球遊技機における動作について説明する。遊技盤3 の上部側に発射された遊技球が第１始動手段14を通過すると、第１乱数選択手段59がその時点の乱数を選択し、その乱数に従って第１図柄表示制御手段60が乱数判定、その他の処理を行い、第１図柄表示手段19の遊技図柄を所定時間変動させる。
【００４３】
第１乱数選択手段59が選択した乱数値が当たり乱数値であれば、第１図柄表示手段19の遊技図柄が当たり図柄で停止し、開閉制御手段61が働いて第２始動手段12の一対の開閉爪12a が開放する。このため第２始動手段12に遊技球が入賞し易くなり、それだけ第２図柄表示手段18の遊技図柄が変動し易くなる。
【００４４】
第２始動手段12に遊技球が入賞すると、第２乱数選択手段62がその時点の乱数値を選択し、第２図柄表示制御手段63が乱数処理により大当たり乱数値か否かを判定し、その判定結果に従って所定の停止図柄で停止するように、第２図柄表示手段18に表示される遊技図柄を所定の変動パターンで所定時間変動させる。
【００４５】
変動後に３個の停止図柄が「７・７・７」等の特定図柄、即ち大当たり図柄を表示すると、利益状態発生手段65が働いて可変入賞手段13の開閉板22〜24の全て又は一部が前側に開放する利益状態が発生する。このため遊技盤3 の上部側から落下する遊技球の多くが開閉板22〜24を経て可変入賞手段13に入賞し易くなり、これによって第２図柄表示手段18側で一旦大当たりが発生すれば、遊技者に多大な利益が還元されることになる。
【００４６】
このとき第２図柄表示手段18の変動後の停止図柄の種類に応じて入賞領域制御部67が働き、可変入賞手段13の開放すべき開閉板22〜24を決定する領域制御信号を開閉制御部66に送信する。従って、利益状態発生手段65により利益状態が発生した場合でも、その大当たり図柄の種類の如何によって入賞領域が３段階に変化し、遊技盤3 に沿って落下する遊技球が可変入賞手段13に入賞するときの入賞効率が変化する。
【００４７】
即ち、「０・０・０」〜「９・９・９」の１０種類の大当たり図柄の内、変動後の停止図柄が偶数図柄の組み合わせのときには、中央の主駆動手段36のソレノイド40に通電し、中央の主開閉板22が横軸34廻りに回動して開状態になるので、可変入賞手段13の入賞領域は狭領域A3となり、その主開閉板22によって遊技球を入賞口21へと案内する。このため、可変入賞手段13は、主開閉板22の開放後から所定時間経過するか、又は１個の遊技球が入賞するまで開状態を保っているが、主開閉板22上に落下する遊技球が入賞口21へと入賞するのみであり、遊技球が入賞口21に入賞するときの入賞効率が他の場合に比較して悪くなる。
【００４８】
しかし、変動後の停止図柄が「１・１・１」、「５・５・５」又は「９・９・９」のときには、２個の駆動手段36,38 のソレノイド40,46 に通電し、２個の開閉板22,24 が横軸34廻りに回動して開状態になり、可変入賞手段13の入賞領域が中領域A2となる。このため２個の開閉板22,24 によって遊技球を入賞口21へと案内するので、遊技球は主開閉板22のみが開放する狭領域A3の場合に比較して、入賞口21への入賞効率が向上する。
【００４９】
また「３・３・３」又は「７・７・７」のときには、３個の駆動手段36〜38のソレノイド40,45,46に通電し、３個の開閉板22〜24が横軸34廻りに回動して開状態になるので、可変入賞手段13の入賞領域が広領域A1となり、その３個の開閉板22〜24によって遊技球を入賞口21へと案内する。このため主開閉板22、又は主開閉板22と一方の副開閉板24が開放する場合に比較して、遊技球は効率的に入賞口21へと入賞する。
【００５０】
入賞口21に入賞した遊技球は、特定領域27又は入賞通路28,29 を経て遊技盤3 の裏側へと案内され、その遊技球を計数スイッチ33が検出する。そして、計数スイッチ33が１０個の遊技球を検出したとき、又は開閉板22〜24の開放後に所定時間が経過したときに、開閉制御部66によりソレノイド40,45,46への通電が遮断して開閉板22〜24が閉じる。また遊技球が特定領域27を通過すると、特定領域検出スイッチ32が遊技球を検出することを条件に、最大１６回まで開閉動作を繰り返す。
【００５１】
このように同じ大当たりの場合でも、変動後の停止図柄の種類の如何によって、可変入賞手段13の入賞領域が複数段階に段階的に変化するため、変動後の停止図柄の種類が遊技者の関心事となり、変化に富み遊技者の興趣を向上できる利点がある。
【００５２】
また可変入賞手段13の入賞領域が変化すると、広領域A1のときに各開閉板22〜24に対応する表示ランプ58が、中領域A2のときに主開閉板22及び副開閉板24に対応する表示ランプ58が、狭領域A3のときに主開閉板22に対応する表示ランプ58が夫々点滅発光して、その入賞領域の変化を遊技者に対して表示する。このため、遊技者は、表示ランプ58の点滅発光によって入賞領域の変化を容易に把握することができる。
【００５３】
図９は本発明の第２の実施形態を例示し、主開閉板22の一側に２個の副開閉板23,24 を配置したものである。このように１個の主開閉板22と２個の副開閉板23,24 とによって入賞領域を変化させる場合、その各開閉板22〜24の配置は種々に変更可能である。勿論、２個の副開閉板23,24 の内、何れか１個の副開閉板23又は副開閉板24を主開閉板22と組み合わせるようにしても良い。
【００５４】
またその他、開閉板の数は４個以上でも良いし、各開閉板の左右の幅は同じにしても良い。要するに入賞領域変化手段25は、開閉する開閉板22〜24の数の変化によって、入賞領域が段階的に変化する構造であれば十分である。しかし、開閉板22〜24の何れか１個が開放したときに、特定領域27への遊技球の入賞の可能性を持たせるようにすることが望ましい。
【００５５】
図１０は本発明の第３の実施形態を例示し、同一幅又は略同一幅の２個の開閉板22,23 を入賞口21の左右に配置したものである。この場合にも、同様に実施できる。但し、この場合にも、特定領域27を左右方向の略中央に配置し、２個の開閉板22,23 の内、その何れか一方が開放したときに、特定領域27へと遊技球が入賞する可能性が生じるようにすることが望ましい。
【００５６】
図１１は本発明の第４の実施形態を例示し、この実施形態の入賞領域変化手段25は、入賞ケース20の庇部69の下側に左右方向に摺動自在に配置された左右一対の球案内体70,71 を備え、この各球案内体70,71 を図外の駆動手段により逆方向に摺動させて入賞領域を変化させるようにしたものである。
【００５７】
各球案内体70,71 は、Ｌ字状、その他の所定形状に構成され、図外のラック・ピニオン機構、リンク機構等を介して駆動手段のモータ、ソレノイド等に連動連結され、第２図柄表示手段18の変動後の停止図柄が大当たり図柄のときに、その停止図柄の種類に応じて実線の閉状態から一点鎖線の狭領域A3、二点鎖線の広領域A1に夫々入賞領域が変化すべく駆動手段により駆動されるようになっている。
また入賞ケース20の上部及び／又は球案内体70,71 に、入賞領域表示手段57を構成する表示ランプ58が設けられている。
【００５８】
このように球案内体70,71 の左右方向への摺動により入賞領域を変化させるように構成しても、第１の実施形態と同様に実施することができる。また球案内体70,71 に表示ランプ58を設ける場合には、球案内体70,71 の摺動によって表示ランプ58の位置が変化するので、入賞領域の変化を容易に把握できる。
【００５９】
以上、本発明の各実施形態について詳述したが、本発明はこの実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲で種々の変更が可能である。
【００６０】
例えば、３個の開閉板22〜24を備えた可変入賞手段13の場合、大当たり発生で開閉板23を開状態にし、その後の所定条件の達成（例えば３個入賞）で開閉板24を開状態にし、次の所定条件の達成（例えば３個入賞）で開閉板22を開状態にしても良い。即ち、複数個の開閉体22〜24を大当たりの発生後、所定の条件を達成する都度、順次開放させるように構成し、全開状態に近づくに従って特定領域27への入賞の遊技者の期待感が向上するようにしても良い。

[Prior art]
In a ball game machine such as a pachinko machine, one or more symbols of the symbol display means fluctuate for a predetermined time on condition that the starting means detects the game ball, and the stopped symbol after the fluctuation is displayed. When a predetermined symbol (so-called jackpot symbol) is determined, a profit state is generated by the profit state generating means, and the variable winning means performs a conversion operation between a first state advantageous to the player and an unfavorable second state. There is something like that.
[0003]
The variable winning means constitutes so-called big winning means, and when the stop symbol of the symbol display means is a big hit symbol, the opening and closing plate rotates upwardly around the horizontal axis to open the winning opening, A game ball falling from above along the game board is guided to the winning opening by an opening / closing plate. The winning area of the variable winning means is determined by the left and right width of the opening / closing plate, and is usually constant in the range of 55 mm to 90 mm.
[0004]
[Problems to be solved by the invention]
The variable winning means is usually a predetermined number of times on the condition that a predetermined time elapses after opening or the opening / closing plate is closed when 10 game balls are won and the game balls won during the opening pass a specific area. For example, the opening / closing operation is repeated up to 16 times. Therefore, if a profit state is generated by the profit state generating means, the player can receive a great return of profit by opening and closing the variable winning means.
[0005]

It has become. The winning area display means 57 may be provided at a place other than the variable winning means 13, or the change in the winning area may be directly displayed with characters or the like.
[0030]
FIG. 8 is a block diagram illustrating a control system. 59 is a first random number selection means that repeatedly generates a hit / miss determination random number and selects the random number at that time on condition that the first starting means 14 detects a game ball. 60 is a first symbol display control means, which is selected by the first random number selection means 59 by changing the game symbol of the first symbol display means 19 for a predetermined time on condition that the first starting means 14 detects a game ball. The game symbol is stopped at the winning symbol or the losing symbol according to the winning random number or the losing random number.
[0031]
61 is an opening / closing control means. When the stop symbol after the first symbol display means 19 changes is stopped at a winning symbol such as “7”, the pair of opening / closing claws 12a of the second starting means 12 are opened for a predetermined time. The second starting means 12 is configured to be controlled so that a game ball can easily win a prize.
[0032]
62 is a second random number selection means, which repeatedly generates predetermined random numbers such as a jackpot / loss determination random number, a variation pattern determination random number, a stop symbol determination random number, etc., and the second start means 12 detects a game ball The random number is selected on the condition. The second random number selection means 62 generates, for example, a random number for determining a big hit / loss from 0 to 249 when the probability of the big hit occurrence that the stop symbol of the second symbol display means 18 becomes a big hit symbol is 1/250. To do.
[0033]
63 is a second symbol display control means, on condition that a game ball wins the second starting means 12, the big hit / out decision random number selected by the second random number selection means 62, the random number for variation pattern determination, the stop Each game symbol of the second symbol display means 18 is varied for a predetermined time according to the symbol determining random number, etc., and is stopped. For example, when the second random number selection means 62 selects a jackpot random value, the variation pattern Through the variation pattern determined by the random number for determination, the game symbol is stopped by a combination of specific symbols determined by the symbol random number, for example, a stop symbol such as “7/7/7”.
[0034]
64 is a storage means. When a game ball is won in the second starting means 12 while the game symbol of the second symbol display means 18 is changing, the winning symbol is stored up to a predetermined number (for example, four). Each time the changing operation of the display means 18 is completed, the game symbols of the second symbol display means 18 are changed in accordance with the number of stored information.
[0035]
65 is a profit state generating means. When the second random number selecting means 62 selects a jackpot random number value and the game symbol after the change of the second symbol display means 18 is a jackpot that is a combination of specific symbols, the variable winning means 13 Is converted from the second state to the first state, and a specific profit state advantageous to the player is generated.
[0036]
That is, the profit state generating means 65 is a jackpot / outgoing random number drawn by the second random number selecting means 62 at the time of winning the game ball to the second starting means 12 and / or a stop symbol after the second symbol display means 18 is changed. If the game symbol stop symbol after the second symbol display means 18 changes to a jackpot symbol such as “7/7/7”, the opening / closing plate 22 of the variable winning means 13 is determined. -24 are opened to generate a profit state advantageous to the player.
[0037]
The profit state generating means 65 includes a jackpot determination unit 73 for determining whether the winning symbol is a big hit from the stopped symbol after the change of the second symbol display means 18 and generating a profit state advantageous to the player, In addition to the open / close control unit 66 that controls opening / closing of the open / close plates 22 to 24 of the variable winning means 13 when the stop symbol after the change of the symbol display means 18 becomes a big hit symbol, the variable winning according to the type of the big hit symbol A winning area control unit 67 that controls the winning area of the means 13 to change stepwise in a plurality of stages and a winning area display control unit 68 that controls the display of the winning area display means 57 are provided.
[0038]
In the winning area control unit 67, the winning area of the variable winning means 13 is set according to the type of the jackpot symbol, respectively, and when the stop symbol after the change displays the predetermined type of jackpot symbol, the variable winning means 13 A control signal is sent to the open / close control unit 66 so as to change the winning area in accordance with the type of the jackpot symbol.
[0039]
For example, the winning area control unit 67 is “3.3.3” and “7.7.7” among the ten types of jackpot symbols from “0.0.0” to “9.9.9”. When the driving means 36 to 38 of the winning area changing means 25 are activated, the winning area becomes the wide area A1, and when “1 · 1 · 1”, “5 · 5 · 5” and “9 · 9 · 9” The drive means 36 and 38 are operated to be in the middle area A2, and the drive means 36 is operated to be in the narrow area A3 for other even symbols. Send to 66.
[0040]
The winning area display control unit 68 selects “3.3.3” and “7.7.7” out of 10 types of jackpot symbols from “0.0.0” to “9.9.9”. The indicator lamps 58 corresponding to the open / close plates 22 to 24 correspond to the main open / close plate 22 and the sub open / close plate 24 when “1, 1, 1”, “5, 5, 5”, and “9, 9, 9”. When the display lamp 58 to be displayed is in another pattern, the display lamps 58 corresponding to the main opening / closing plate 22 are caused to blink.
[0041]
The profit state generating means 65 continues the opening / closing operation up to a predetermined number of times (for example, 16 times at the maximum) on condition that the game ball won while the opening / closing plates 22 to 24 are opened passes through the specific area 27. It has become.
[0042]
Next, the operation of the above-mentioned bullet ball game machine will be described. When the game ball launched on the upper side of the game board 3 passes through the first starting means 14, the first random number selecting means 59 selects the random number at that time, and the first symbol display control means 60 determines the random number according to the random number. Then, other processing is performed to change the game symbol of the first symbol display means 19 for a predetermined time.
[0043]
If the random number value selected by the first random number selection means 59 is a winning random number value, the game symbol of the first symbol display means 19 stops at the winning symbol, and the opening / closing control means 61 is activated to operate a pair of second starting means 12 The opening / closing claw 12a opens. For this reason, it becomes easy for a game ball to win the second starting means 12, and the game symbol of the second symbol display means 18 is easily changed accordingly.
[0044]
When a game ball wins the second starting means 12, the second random number selecting means 62 selects a random number value at that time, and the second symbol display control means 63 determines whether or not it is a big hit random number value by random number processing, The game symbols displayed on the second symbol display means 18 are varied for a predetermined time with a predetermined variation pattern so as to stop at a predetermined stop symbol according to the determination result.
[0045]
After the change, when the 3 stop symbols display a specific symbol such as “7, 7, 7”, that is, a jackpot symbol, the profit state generating means 65 works and all or part of the open / close plates 22 to 24 of the variable winning means 13 A profit state occurs that opens to the front side. For this reason, many of the game balls falling from the upper side of the game board 3 are likely to win the variable winning means 13 through the opening and closing plates 22 to 24, and once a big hit occurs on the second symbol display means 18 side, A huge profit will be returned to the player.
[0046]
At this time, the winning area control unit 67 operates according to the type of the stopped symbol after the change of the second symbol display means 18, and the area control signal for determining the opening / closing plates 22 to 24 of the variable winning means 13 is opened and closed. Send to 66. Therefore, even if a profit state is generated by the profit state generating means 65, the winning area changes in three stages depending on the type of the jackpot symbol, and the game ball falling along the game board 3 wins the variable winning means 13 The winning efficiency when you change.
[0047]
That is, among the 10 jackpot symbols from “0.0.0” to “9.9.9”, when the stop symbol after fluctuation is an even symbol combination, the solenoid 40 of the central main drive means 36 is energized. However, since the central main opening / closing plate 22 rotates around the horizontal axis 34 to be in the open state, the winning area of the variable winning means 13 becomes a narrow area A3, and the main opening / closing plate 22 moves the game ball to the winning opening 21. I will guide you. For this reason, the variable winning means 13 is kept open until a predetermined time elapses after the main opening / closing plate 22 is opened or until one game ball is won, but the game that falls on the main opening / closing plate 22 The ball only wins the winning opening 21, and the winning efficiency when the game ball wins the winning opening 21 is worse than in other cases.
[0048]
However, when the stop pattern after the change is “1, 1, 1”, “5, 5, 5” or “9, 9, 9”, the solenoids 40, 46 of the two drive means 36, 38 are energized. The two open / close plates 22 and 24 are rotated around the horizontal axis 34 to be in the open state, and the winning area of the variable winning means 13 is the middle area A2. For this reason, the game balls are guided to the winning opening 21 by the two opening and closing plates 22 and 24, so that the gaming balls are awarded to the winning opening 21 as compared to the narrow area A3 where only the main opening and closing plate 22 opens. Efficiency is improved.
[0049]
In the case of “3, 3, 3” or “7, 7, 7”, the solenoids 40, 45, 46 of the three driving means 36 to 38 are energized, and the three open / close plates 22 to 24 are connected to the horizontal axis 34. Since it is turned around and opened, the winning area of the variable winning means 13 becomes the wide area A1, and the game balls are guided to the winning opening 21 by the three opening / closing plates 22-24. For this reason, the game ball wins the winning opening 21 more efficiently than when the main opening / closing plate 22 or the main opening / closing plate 22 and one of the sub opening / closing plates 24 are opened.
[0050]
The game ball that has won the winning opening 21 is guided to the back side of the game board 3 through the specific area 27 or the winning passages 28 and 29, and the counting switch 33 detects the game ball. When the counting switch 33 detects 10 game balls, or when a predetermined time has elapsed after the opening of the opening / closing plates 22 to 24, the opening / closing controller 66 cuts off the energization of the solenoids 40, 45, 46. Opening and closing plates 22 to 24 are closed. When the game ball passes through the specific area 27, the opening / closing operation is repeated up to 16 times on condition that the specific area detection switch 32 detects the game ball.
[0051]
In this way, even in the case of the same jackpot, the winning area of the variable winning means 13 changes step by step depending on the type of stop symbol after the change, so the type of stop symbol after the change is the player's interest. As a result, there is an advantage that it is rich in change and can improve the interest of the player.
[0052]
When the winning area of the variable winning means 13 is changed, the display lamps 58 corresponding to the opening / closing plates 22 to 24 in the wide area A1 correspond to the main opening / closing plate 22 and the auxiliary opening / closing plate 24 in the middle area A2. When the display lamp 58 is in the narrow area A3, the display lamps 58 corresponding to the main opening / closing plate 22 each flash and emit light, and the change of the winning area is displayed to the player. Therefore, the player can easily grasp the change of the winning area by the flashing light emission of the display lamp 58.
[0053]
FIG. 9 illustrates a second embodiment of the present invention, in which two sub opening / closing plates 23 and 24 are arranged on one side of the main opening / closing plate 22. When the winning area is changed by one main opening / closing plate 22 and two sub opening / closing plates 23, 24, the arrangement of the opening / closing plates 22-24 can be variously changed. Of course, any one of the two auxiliary opening / closing plates 23, 24 may be combined with the main opening / closing plate 22.
[0054]
In addition, the number of open / close plates may be four or more, and the left and right widths of the open / close plates may be the same. In short, it is sufficient that the winning area changing means 25 has a structure in which the winning area changes step by step according to the change in the number of the open / close plates 22 to 24 that are opened and closed. However, when any one of the opening / closing plates 22 to 24 is opened, it is desirable to give a possibility of winning a game ball to the specific area 27.
[0055]
FIG. 10 illustrates a third embodiment of the present invention, in which two opening / closing plates 22 and 23 having the same width or substantially the same width are arranged on the left and right of the winning opening 21. In this case, the same can be implemented. However, also in this case, when the specific area 27 is arranged substantially in the center in the left-right direction and one of the two opening / closing plates 22 and 23 is opened, the game ball wins the specific area 27 It is desirable to have the possibility of doing so.
[0056]
FIG. 11 illustrates a fourth embodiment of the present invention, and the winning area changing means 25 of this embodiment is a pair of left and right slidably arranged in the left-right direction below the collar portion 69 of the winning case 20. The ball guide bodies 70 and 71 are provided, and each of the ball guide bodies 70 and 71 is slid in the reverse direction by a driving means (not shown) to change the winning area.

Each of the ball guide bodies 70 and 71 is configured in an L shape or other predetermined shape, and is linked to a motor, a solenoid or the like of a driving means via a rack and pinion mechanism, a link mechanism, etc., which is not shown in the figure. When the stop symbol after the change of the display means 18 is a jackpot symbol, the winning area changes from the closed state of the solid line to the narrow area A3 of the alternate long and short dashed line and the wide area A1 of the alternate long and two short dashed line according to the type of the stopped symbol Therefore, it is driven by the driving means.
The upper portion of the winning case 20 and / or the ball guide bodies 70 and 71 are provided with a display lamp 58 constituting the winning area display means 57.
[0058]
Even if the winning area is changed by sliding the ball guide bodies 70 and 71 in the left-right direction as described above, the same operation as in the first embodiment can be performed. When the display lamps 58 are provided on the ball guides 70 and 71, the position of the display lamps 58 is changed by the sliding of the ball guides 70 and 71, so that the change in the winning area can be easily grasped.
[0059]
As mentioned above, although each embodiment of this invention was explained in full detail, this invention is not limited to this embodiment, A various change is possible in the range which does not deviate from the meaning of this invention.
[0060]
For example, in the case of the variable winning means 13 having three open / close plates 22 to 24, the open / close plate 23 is opened when a big hit occurs, and the open / close plate 24 is opened when a predetermined condition is achieved (for example, 3 wins). Then, the opening / closing plate 22 may be opened when the following predetermined condition is achieved (for example, three winnings). That is, a plurality of opening / closing bodies 22 to 24 are configured to be opened sequentially every time a predetermined condition is achieved after a big hit occurs, and the player's expectation of winning a prize in the specific area 27 is increased as the fully opened state is approached.
