Description

【０００１】
【発明の属する技術分野】
本発明は、打球供給皿を有する前面板を開閉自在に設けてなるパチンコ遊技機に関し、特に打球供給皿に貯留される打球を１個ずつ発射レールの発射位置に供給する自動球送り装置が前面板と分離して前面枠体側に設けられたパチンコ遊技機に関するものである。
【０００２】
【従来の技術】
従来のパチンコ遊技機は、周知のように縦長の方形状に枠組形成された外枠と，該外枠の一側に開閉自在に軸支される前面枠とを有し、該前面枠の裏面に遊技盤取付枠を介して遊技盤が着脱自在に装着されている。また，前面枠の前面には、遊技盤の遊技領域を覆うガラス板保持枠及び打球供給皿を有する前面板が開閉自在に設けられており、前面板の裏面には打球杆の発射動作に連動して打球供給皿に貯留される打球を１個ずつ発射レールの発射位置に供給する自動球送り装置が取り付けられている。
【０００３】
【発明が解決しようとする課題】
上記のように自動球送り装置が前面板の裏面に取り付けられた従来のパチンコ遊技機にあっては、前面板に開設された打球供給皿の球出口が自動球送り装置によって塞がれた状態になっているため、前面板を開放しても打球供給皿の打球が球出口から零れ落ちるようなことがなく、従って前面板を開放する際にあらかじめ打球供給皿の打球を抜き取るような面倒な作業が不要となる。しかし、その反面自動球送り装置が前面板の裏面に取り付けられていると遊技者が打球供給皿に手を乗せたり或いは打球供給皿に貯留される打球の重さによって前面板が歪んだりするようなことがあり、その結果発射レールの発射位置と自動球送り装置の供給口との対応位置関係に狂いが生じて正確な打球の供給動作が行われなくなるという問題点が発生する。
【０００４】
本発明は、上記した問題点に鑑みてなされたもので、その目的とするところは、自動球送り装置を前面板と分離して前面枠体側に設けることにより打球供給皿の打球を安定した状態で発射レールの発射位置に供給できるようにすると共に、前面板を係止する係止手段を利用して打球供給皿の球出口を開放したり閉鎖したりするようにして前面板を開放する際に打球供給皿の打球を抜き取る面倒な手間を不要とすることができるようなパチンコ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】
上記した目的を達成するために、本発明は、外枠と、該外枠の一側に開閉自在に取り付けられる前面枠体とを有し、該前面枠体の前面に打球供給皿を有する前面板を開閉自在に設けてなるパチンコ遊技機において、前記打球供給皿に貯留される打球を１個ずつ発射レールの発射位置に供給する自動球送り装置を前面板と分離して前面枠体側に装着すると共に、前面板の開放側内側面に係止手段を設け、前記係止手段は、前面枠体の係止部に係合して前面板を閉止する第１位置及び前面枠体の係止部との係合を解除する第２位置とに移動可能に設けられ、かつ球止板が固着された係止レバーと、該係止レバーを常に第１位置に付勢する付勢部材と、前記係止レバーを第２位置に係止保持すると共に、前面板を閉止することにより係止レバーの係止を解除するロック部材とから構成されており、前記球止板は、係止レバーが第１位置のとき前面板に開設された打球供給皿の球出口を開放して自動球送り装置に打球を供給可能とし、係止レバーが第２位置に移動したとき打球供給皿の球出口を閉鎖するように設けられていることを特徴としている。
【０００６】
このように構成することにより、係止レバーが無用に移動して前面板の閉止動作に支障を及ぼすようなことを無くすことができると共に、前面板を開放する際に打球供給皿の打球を抜き取るような面倒な手間を不要とすることが可能となる。
【０００７】
【発明の実施の形態】
次に、図面を参照して本発明の一実施の形態を説明する。図１はパチンコ遊技機の正面図、図２はパチンコ遊技機の裏面図、図３はガラス板保持枠と打球供給皿を有する前面板及び余剰球受皿を有する前面下部板を開いた状態の斜視図、図４は前面枠体の斜視図である。図１において、パチンコ遊技機１は、縦長な方形状に枠組み形成される外枠２と、該外枠２の一側にヒンジ機構３、３によって開閉自在に装着される前面枠体４とを備え、該前面枠体４の前面一側にガラス板保持枠５と、打球供給皿６を有する前面板７及び余剰球受皿８を有する前面下部板９とがそれぞれ開閉自在に軸支されている。また、前面下部板９には打球発射用の操作ハンドル１０が設けられている。
【０００８】
前記前面枠体４は、図４に示すように鉄板等の金属板によって形成されるもので、上部にほぼ正方形状の開口部１１が形成され、その下部が板状部１２ａとして形成された主枠部１２と、該主枠部１２の裏面側であり、開口部１１の上側位置を除く左右両側位置及び下側位置にそれぞれカシメ着されて該主枠部１２と一体化される遊技盤取付枠１３とを有し、その遊技盤取付枠１３であり、かつ主枠部１２の開口部１１を覆うように遊技盤１４が着脱可能に取り付けられるようになっている。
【０００９】
また、前記前面枠体４の前面であり、かつその軸支側の上端にガラス板保持枠５の一側上端を軸支するための下向きのヒンジ軸１５を突設した支持体１６が固着され、中程よりやや下方位置にガラス板保持枠５の一側下端と前面板７及び前面下部板９とを軸支するためのヒンジ金具１７が固着されている。このヒンジ金具１７は、上下両端に水平な支持片１８ａ，１８ｂを有するコ字形に形成されており、両支持片１８ａ，１８ｂにヒンジ軸杆１９が貫通されている。このヒンジ軸杆１９の下端は前面枠体４の前方に突出する下部ヒンジ機構３の支持板部２０に固着されており、その上端が上部の支持片１８ａから上方に突出されている。そして、その上部の支持片１８ａから上方に突出するヒンジ軸杆１９にガラス板保持枠５の一側下端が軸支され、両支持片１８ａ，１８ｂ間に位置するヒンジ軸杆１９に前面板７が軸支され、さらに下部の支持片１８ｂと前面枠体４の下部ヒンジ機構３の支持板部２０間に位置するヒンジ軸杆１９に前面下部板９が軸支されるようになっている。
【００１０】
一方、前記前面枠体４の主枠部１２であり、開口部１１の下方の板状部１２ａには、円形状の取付孔２１とほぼ四角形状の取付孔２２が貫通形成されている。円形状の取付孔２１の周囲には複数の係合孔２３と、縦溝孔２４，２４が間隔を離して対向状に設けられており、さらに円形状取付孔２１の両側位置にＵ字形の切欠溝２５により弾性が付与された弾圧片２６，２６が形成されている。前記複数の係合孔２３は大径孔部２３ａと小径孔部２３ｂとが連通状に設けられた鍵穴形状のものである。また、前記弾圧片２６には小突起２７が一体に突設されている。
【００１１】
そして、前記前面枠体４の主枠部１２前面には、図３に示すように遊技盤１４の遊技領域外を覆うように合成樹脂により形成されたレール飾り部材２８と、同じように合成樹脂により形成されたレール変形防止部材２９が設けられ、遊技盤１４の遊技領域外には、証紙貼付部材３０等が設けられている。また、前記円形状の取付孔２１には後述する打球発射機構３１が取り付けられ、四角形状の取付孔２２には通路構成体３２が着脱自在に装着されるようになっている。
【００１２】
一方、図２に示すように前記前面枠体４の裏面には、合成樹脂製の機構板３３が上下のヒンジ３４，３４を介して着脱及び開閉自在に設けられている。この機構板３３は、遊技盤１４の裏面に相対する板状部を有し、該板状部の前面に入賞球集合カバー３５が収納される入賞球集合空間が形成され、その入賞球集合空間の下方部に樋状の入賞球集合部３３ａが設けられている。また、機構板３３の板状部の裏面上部には貯留球タンク３６と、該貯留球タンク３６に貯留された球を下流側に整列しながら誘導する球誘導樋３７が設けられており、さらに球誘導樋３７の下流側には屈曲誘導樋３８を介して賞球払出装置３９が着脱可能に設けられている。また、賞球払出装置３９の下方には、払い出された賞球を打球供給皿６に導く賞球排出通路４０、該打球供給皿６の余剰球出口４１の側方に連通状に設けられる余剰球通路４２、アウト球通路４３、球抜通路４４等が設けられており、余剰球通路４２の流下端が前記通路構成体３２の余剰球誘導通路４５に連通され、アウト球通路４３の流下端が前記通路構成体３２のアウト球排出通路部４６に連通され、さらに球抜通路４４の流下端が前記通路構成体３２の球抜き排出通路部４７にそれぞれ連通されるようになっている。
【００１３】
前記打球発射機構３１は、図５乃至図８に示すように発射レール４８と、該発射レール４８の発射位置に臨む打球杆４９と、該打球杆４９の回動範囲を規制するストッパー５０，５０と、打球杆４９の駆動源としてのロータリーソレノイド５１と、打球杆４９の発射動作に連動して打球供給皿６に貯留される打球を１個ずつ発射レール４８の発射位置に供給する自動球送り装置５２とをそれぞれ保持体５３に一体に組付けてユニット化されている。
【００１４】
前記保持体５３は、肉厚に形成された１枚の金属板により形成されており、該保持体５３には、図７に示すようにロータリーソレノイド５１をビス止めするための複数の取付孔５４やロータリーソレノイド５１の駆動軸５５を臨ませるための透孔５６が穿設されている。また、保持体５３の表側には、発射レール４８を取り付けるための複数の取着凸部５７や自動球送り装置５２を取り付けるための間隔保持突起５８、或いは打球杆４９のストッパー取付部５９、把手片６０等が一体に設けられており、保持体５３の裏側には主枠部１２の板状部１２ａに設けられた係合孔２３に嵌合する複数の嵌合突起６１と、縦溝孔２４，２４に嵌合する規制突条６２，６２が突設され、さらに、弾圧片２６，２６の小突起２７，２７が嵌合する凹孔６３，６３が設けられている。前記複数の嵌合突起６１は、図８に示すように大径頭部６４と細径基部６５とを一体に有する。
【００１５】
前記発射レール４８は、ステンレスにより上面に浅いＶ字状のガイド溝４８ａが形成された断面門形形状に形成されており、保持体５３の表面側に突設された複数の取着凸部５７にビス止めされるようになっている。詳細に説明すると、前記取着凸部５７は、図９に示すようにその突出長さが発射レール４８の内側間隔とほぼ同一寸法に形成されており、かつその基部に凹溝５７ａが形成されている。そして、発射レール４８の一方の側片部４８ｂを凹溝５７ａに嵌めこんで保持体５３の表面に密着させると共に、他方の側片部４８ｃを取着凸部５７の先端に当接させた後、発射レール４８の取付孔６６から取着凸部５７のねじ孔６７にビス６８を締着することにより強固に取り付けられるようになっている。このように、発射レール４８を取着凸部５７を介して取り付けることにより通常発射レール４８の内側に装着される補強用の中子部材を不要とすることができる。
【００１６】
一方、前記自動球送り装置５２は、図７及び図１０、１１に示すように垂直状の球通路６９を有する通路枠７０と、該通路枠７０の球通路６９に設けられる球供給部材７１と、該球供給部材７１を作動させる電磁石７２とから構成されており、箱状のケース体７３内に一体に収納されている。前記ケース体７３は、前カバー部７３ａと後カバー部７３ｂとの二部材で形成されてねじ７４，７４により一体化されるもので、その後カバー部７３ｂの一側上下部に設けられた軸部材７５，７５を前記保持体５３の表面側に固着されたベース枠７６の軸受部７７に軸支させることにより図５に示す閉止位置と図６に示す開放位置とに開閉できるようになっている。
【００１７】
前記通路枠７０は、ケース体７３の後カバー部７３ｂにねじ７８，７８で固着されており、その球通路６９の上流端が後カバー部７３ｂの後面壁７９に開設された球出口９５に臨まされている。また、前記球供給部材７１は、図１１に示すように発射レール４８と平行に設けられた横軸８１により上下方向へ回動可能に軸支されており、かつ円弧状に形成された球受部８２と横軸８１より下方であり通路枠７０の外方に突出する係合ピン８３とが設けられている。そして、係合ピン８３の突出端が通路枠７０の側方に沿って上下動自在に設けられた連動部材８４の係合溝８５に臨まされている。
【００１８】
一方、前記電磁石７２は、Ｌ字形の支持板８６を一体に備え、該支持板８６の両側縁をケース体７３の前カバー部７３ａと後カバー部７３ｂのそれぞれ内側面に設けられた突条８７，８７間の溝部８８に嵌め合わせることにより通路枠７０の側方に固定されており、その下方に磁性体からなる可動板８９が対設されている。この可動板８９は、後端が支持板８６の下端に形成された係止溝９０に係止されて上下方向へ回動可能なように支持されており、常にはバネ９１によって図１０実線で示す下向きに回動付勢されている。また、可動板８９の先端は、連動部材８４の係合部９２に上方から係合するようになっている。
【００１９】
このように構成された自動球送り装置５２は、図５及び図１１に示すようにケース体７３を閉止した状態のときケース体７３の前カバー部７３ａが前記保持体５３の表面に突設された規制杆９３に当接されてその前カバー部７３ａの前面壁９４が発射レール４８の前縁にほぼ密着するように位置すると共に、球供給部材７１の球受部８２が発射レール４８の発射位置に正しく対峙するようになっている。また、前面板７を閉じた状態においてケース体７３の後カバー部７３ｂであり、その後面壁７９に開設された球導入口９５と前面板７に開設された打球供給皿６の球出口９６とが連通されるようになっている。なお、前面板７の内側には、自動球送り装置５２を正しく位置規制するための位置決め突起９７が突設されており、ケース体７３の後カバー部７３ｂであり、その後面壁７９には位置決め突起９７が嵌合する位置決め孔９８が設けられている。
【００２０】
そして、前記ロータリーソレノイド５１による打球杆４９の発射動作に同期して電磁石７２が励磁されると、該電磁石７２の励磁に伴う可動板８９の吸着作用（図１０鎖線参照）により連動部材８４を介して球供給部材７１が図１１鎖線のように上向き（反時計回り方向）回動され、電磁石７２の消磁に伴う可動板８９の下方への回動（図１０実線位置）により連動部材８４を介して球供給部材７１が下向き（時計回り方向）回動されるもので、球供給部材７１の上向き回動により球通路６９の先頭に位置する打球を球受部８２に受け入れて保持し、球供給部材７１が下向き回動されるとその球受部８２の打球を発射レール４８の発射位置に供給するようになっている。
【００２１】
上記のようにユニット化された打球発射機構３１を前面枠体４の主枠部１２に取り付けるには、図８及び図１２に示すように先ず主枠部１２の板状部１２ａに貫通形成された円形状取付孔２１にロータリーソレノイド５１を前面側から臨ませると共に、嵌合突起６１の大径頭部６４を板状部１２ａに穿設された係合孔２３の大径孔部２３ａに嵌めて保持体５３を板状部１２ａに密着させる。この際に、保持体５３の規制突条６２，６２が板状部１２ａの縦溝孔２４，２４に嵌合されることになり、これによって、該保持体５３が左右方向へがたつかないように確実に位置規制されることになる。次に、この状態で把手片６０を指で押して保持体５３を下方へ押し下げ嵌合突起６１の細径基部６５と係合孔２３の小径孔部２３ｂとを係合させる。この保持体５３の押し下げにより弾圧片２６の小突起２７が保持体５３の凹孔６３，６３に嵌合して該保持体５３が上下方向へがたつかないように確実に位置規制される。これによって、打球発射機構３１を前面枠体４の主枠部１２にビス止めすることなくワンタッチで強固に、かつ正確に取り付けることができる。
【００２２】
また、このようにして、前面枠体４の主枠部１２に取り付けられた打球発射機構３１を取り外すには、保持体５３を上方へ押し上げて嵌合突起６１の細径基部６５を係合孔２３の小径孔部２３ｂから外した後、嵌合突起６１の大径頭部６４を係合孔２３の大径孔部２３ａに一致させることによって簡単に達せられる。そして、自動球送り装置５２をケース体７３に収納して保持体５３に開閉可能に取り付けることにより、零れ球等から自動球送り装置５２をガードすることができると共に、ケース体７３を閉止した状態において発射レール４８の前縁にほぼ密着するケース体７３の前カバー部７３ａが打球杆４９により発射される打球のガイド面となって良好な球とびが得られることになる。また、図６に示すように自動球送り装置５２を開放すれば発射レール４８の拭き掃除や点検、交換作業などが容易となる利点がある。
【００２３】
しかして、図１３乃至図１９に示すように前記前面板７の開放側内側面にはＬ字形固定片９９が固着されており、該Ｌ字形固定片９９に係止手段１００が設けられている。この係止手段１００は、前面板７を閉止したり開放したりするもので、係止レバー１０１と付勢部材としてのコイルばね１０２とロック部材１０３とから大略構成されている。前記係止レバー１０１は、その前側縁に前面枠体４に設けられた板状の係止部１０４に係脱可能な鉤状係止片１０５と、前記ロック部材１０３に設けられた係止爪部１０６が係合可能な係合切欠き部１０７が形成されている。また、係止レバー１０１の上端は直角に折り曲げられて押圧操作部１０８として形成されており、下部位置にはばね掛け部１０９が設けられている。そして、Ｌ字形固定片９９の垂直壁９９ａに設けられたピン１１０，１１０に上下の縦長孔１１１，１１１を挿入して該垂直壁９９ａに沿って上下方向に移動可能であり、かつ図１５に示すように鉤状係止片１０５を前面枠体４の係止部１０４に係合して前面板７を閉止する第１位置及び図１６に示すように鉤状係止片１０５と前面枠体４の係止部１０４との係合を解除する第２位置とに移動可能に設けられている。
【００２４】
一方、前記ロック部材１０３は、図１７及び図１８に示すように係止爪部１０６及び前面枠体４の板状の係止部１０４と当接可能な腕部１１２とを一体に備えて略横Ｌ字形に屈曲形成されており、その屈曲部が軸１１３によりＬ字形固定片９９の垂直壁９９ａに回動自在に軸支されている。また、前記コイルばね１０２は、下端が係止レバー１０１のばね掛け部１０９に掛止され、その上端がロック部材１０３のばね掛け部１１４に掛止されて常に係止レバー１０１を図１５に示す第１位置に付勢するようになっている。また、コイルばね１０２は、前記ロック部材１０３を図１７において常に反時計回り方向に回動付勢するようになっている。なお、前記ロック部材１０３は、図１５に示すように前面板７が閉止された状態のとき腕部１１２が前面枠体４の板状の係止部１０４に当接してその回動が規制されるようになっている。
【００２５】
上記構成の係止手段１００において、図１３及び図１５実線に示すように前面板７が前面枠体４に閉止された状態のとき、図１５及び図１７鎖線で示すようにコイルばね１０２の付勢に抗して押圧操作部１０８を押し下げると、図１６に示すように係止レバー１０１の鉤状係止片１０５と前面枠体４の係止部１０４との係合が解除されて前面板７が開放され、同時に図１８に示すように前記ロック部材１０３の係止爪部１０６が係止レバー１０１の係合切欠き部１０７に係合して係止レバー１０１を第２位置に係止保持する。すなわち、ロック部材１０３は、前面板７が開放されてその腕部１１２が前面枠体４の板状の係止部１０４から離脱すると同時にコイルばね１０２による付勢で図１８において反時計回り方向に回動して係止レバー１０１の係合切欠き部１０７に係合するようになっている。そして，この状態で前面板７を前面枠体４に閉止すると、図１７に示すようにロック部材１０３の腕部１１２が前面枠体４の板状の係止部１０４に当接して該ロック部材１０３がコイルばね１０２の付勢に抗して時計回り方向に回動し、ロック部材１０３の係止爪部１０６と係止レバー１０１の係合切欠き部１０７との係合を解除する。これによって、係止レバー１０１がコイルばね１０２によって第１位置に付勢されて鉤状係止片１０５が前面枠体４の係止部１０４に係合され、前面板７が前面枠体４に閉止される。このように、前面板７を開放する位置で係止レバー１０１をロック部材１０３により係止保持する構成とすることにより、係止レバー１０１が無用に移動して前面板７の閉止動作に支障を及ぼすようなことを無くすことができる。
【００２６】
一方、前記係止レバー１０１には、前面板７に開設された球出口９６を開閉する球止板１１７が一体に固着されている。この球止板１１７は、ステンレス等の金属板からなる薄い板状の弾性体により形成されており、係止レバー１０１が前面板７を閉止する第１位置のときには図１９実線で示すようにその先端球止め部１１７ａが球出口９６の上方に位置して該球出口９６を開放し、係止レバー１０１が前面板７を開放する第２位置のときには図１９鎖線のように係止レバー１０１と一体に下方へ移動して球止め部１１７ａにより球出口９６を閉鎖するようになっている。このように、前面板７を係止又は開放する係止レバー１０１と一体に球止板１１７を設け、係止レバー１０１を下方に押し下げて前面板７を開放したとき球止板１１７により打球供給皿６の球出口９６を閉鎖する構成とすることにより、前面板７を開放する際に打球供給皿６に球が貯留されていても球出口９６から球が零れ落ちるようなことがなくなり、前面板７を開放する度に打球供給皿６の球を抜き取るという面倒な手間を省くことができる。
【００２７】
【発明の効果】
本発明は，以上説明したところから明らかなように，打球供給皿を有する前面板の開放側内側面に、前面板を閉止又は開放する係止手段を設け、該係止手段を、前面枠体の係止部に係合して前面板を閉止する第１位置及び前面枠体の係止部との係合を解除する第２位置とに移動可能に設けられ、かつ球止板が固着された係止レバーと、該係止レバーを常に第１位置に付勢する付勢部材と、該係止レバーを第２位置に係止保持すると共に、前面板を閉止することにより係止レバーの係止を解除するロック部材とから構成し、前面板を開放したとき係止レバーをロック部材により係止保持すると同時に、球止板により前面板に開設された打球供給皿の球出口を閉鎖するようにしたので、係止レバーが無用に移動して前面板の閉止動作に支障を及ぼすようなことを無くすことができると共に、前面板を開放する度に打球供給皿の球を抜き取るという面倒な手間を省くことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a pachinko gaming machine in which a front plate having a hitting ball supply tray is provided so as to be openable and closable, and in particular, an automatic ball feeding device for supplying hitting balls stored in a hitting ball supply tray one by one to a launch position of a launch rail is provided. The present invention relates to a pachinko gaming machine that is separated from a face plate and provided on the front frame side.
[0002]
[Prior art]
A conventional pachinko gaming machine has an outer frame formed in a vertically long rectangular frame as is well known, and a front frame that is pivotally supported on one side of the outer frame so as to be openable and closable. The game board is detachably attached to the game board via a game board mounting frame. In addition, a front plate having a glass plate holding frame and a hitting ball supply tray covering the game area of the game board is provided on the front surface of the front board so as to be freely opened and closed. An automatic ball feeder is attached to supply the hitting balls stored in the hitting ball supply tray one by one to the launching position of the launching rail.
[0003]
[Problems to be solved by the invention]
In the conventional pachinko gaming machine in which the automatic ball feeder is attached to the rear surface of the front plate as described above, the ball outlet of the hitting ball supply tray established on the front plate is blocked by the automatic ball feeder. Therefore, even if the front plate is opened, the hit ball of the hitting tray does not spill from the outlet of the ball, so that it is troublesome to pull out the hit ball of the hitting tray in advance when opening the front plate. Work becomes unnecessary. However, on the other hand, if the automatic ball feeder is attached to the back of the front plate, the player puts his hand on the ball supply tray or the front plate is distorted by the weight of the ball stored in the ball supply tray. As a result, there arises a problem that the corresponding positional relationship between the launch position of the launch rail and the supply port of the automatic ball feeder is out of order, and an accurate hitting operation cannot be performed.
[0004]
