Description

【０００１】
【発明の属する技術分野】
本発明は、制御基板を備えたパチンコ機などの遊技機に関するものである。
【０００２】
【従来の技術】
代表的な遊技機であるパチンコ機を例に挙げて説明すると、パチンコ機を複数設置した島内には、遊技球を循環するために球回収樋や球補給樋などの長い循環経路が形成されており、これらの経路内を遊技球が転動すると、途中の摩擦等により遊技球が帯電したり、また循環経路内に組み込まれた球磨き装置等で研磨された際に同じく遊技球が帯電する。
【０００３】
一方、パチンコ機には、遊技盤の役物等にモーターやソレノイド等の電気的駆動源や液晶表示装置などの電気部品が複数設けられており、これらの電気部品を制御する制御基板も設けられている。そして制御基板は、プラスチック製制御基板収納部材の内部に収納されて制御ユニットとして、パチンコ機の背面に取り付けられている。
ところで、この様な制御ユニットにおいては、制御基板が、前述した遊技球の静電気や電気的駆動源から発生するノイズの影響を受けないように対策する必要がある。
【０００４】
このため、従来は、制御基板収納部材は合成樹脂等により構成するが、この制御基板収納部材内における制御基板のグランド（即ちアース面のこと。以下ＧＮＤという。）に、例えば金属製の導電性プレートを導通可能に接続して、制御基板に静電気などの影響が及ばないようにしていた。
【０００５】
【発明が解決しようとする課題】
ところが、上記した従来のパチンコ機にあっては、金属製の導電性プレートが単なる平板であるため、導電性プレートの端部に配線等が引っ掛かり易かった。
【０００６】
本発明は、前記した事情に鑑み提案されたもので、導電性プレートの構造を改良することにより、配線等が引っ掛かり難い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】
上記目的達成のため、請求項１記載のものは、電気部品を制御する制御基板を取付可能な取付ベースと、該取付ベースと合わさって制御基板を覆う上蓋部材とからなる制御基板収納部材と、
該制御基板収納部材の裏面側に取り付けられる導電性部材と、
を備え、
前記取付ベースには、当該取付ベースの内外を連通させる円筒状の連通部を形成し、該連通部に導通補助部材を挿嵌して該導通補助部材と前記制御基板のグランドとを導通させ、前記導通補助部材と前記導電性部材とを圧接して導通させる遊技機において、
前記取付ベースの周縁部には上蓋部材側へ起立する支持壁を形成し、該支持壁の先端部分に外側に折り返した折返し部を形成して概ね逆Ｕ字状を呈し、該折返し部と前記支持壁との間に凹室部を区画形成し、
前記支持壁の上端部には、隆起部を設け、該隆起部の内側に前記制御基板を載置する基板載置部を形成するとともに、前記隆起部の外側に前記上蓋部材の周縁部を載置する上蓋載置部を形成し、
前記導電性部材の周縁部には、前記上蓋部材側へ起立する起立壁を形成し、該起立壁を前記凹室部に収容したことを特徴とする遊技機である。
【０００８】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して説明する。
図１は代表的な遊技機であるパチンコ遊技機（以下、パチンコ機１という。）の背面図、図２は制御ユニットの裏面外観を示す背面図、図３は制御ユニット及び導電性部材の取付構造における第１実施形態を示す図２のＡ線矢視断面図である。
【０００９】
パチンコ機１は、機枠４の前面開口部分に額縁状の前面枠（図示せず）を開閉可能に取り付け、この前面枠の開口部分を裏側から塞ぐようにして遊技盤５を取り付け、この遊技盤５の表面に、ガイドレール等の区画部材により区画して形成した遊技領域内に、入賞具、始動口に入賞することを条件として図柄合わせ遊技等の別遊技を行う図柄表示装置、別遊技で大当りになると開く大入賞口などの電気部品を設けてある。また、前面枠の裏側には裏機構盤６を取り付け、この裏機構盤６に裏機構として貯留タンク９、球誘導路１０、半端センサユニット１２、球排出ユニット１３などを取り付けるとともに、前面枠の裏面下部に設けた球発射装置１６および上記球排出ユニット１３を制御する排出制御ユニット１７、前記図柄表示装置や大入賞口などの電気式役物を制御する役物制御ユニット２０、電源供給ユニット７などの制御ユニットを取り付け、遊技盤の裏側には、表示制御ユニット１５ａ、音制御ユニット１５ｂ、装飾制御ユニット１５ｃを設ける。
【００１０】
なお、遊技盤５は前面枠を残して新しいものに交換できるが、その際に役物制御ユニット２０も、新しい遊技盤５に対応したものに交換される。
【００１１】
そして、役物制御ユニット２０の裏面側（裏機構盤６側）には、後述する導電性部材３が取り付けられており、この導電性部材３に備えられている取付部材２１により裏機構盤６に着脱可能な状態で取り付けられている。
【００１２】
次に、役物制御ユニット２０と導電性部材３との取り付け構造等について説明する。なお、説明の便宜上、各部材の裏機構盤６に近い側を基端側とし、裏機構盤６から遠い側を背面側とする。
役物制御ユニット２０は、図２および図３に示すように、図柄表示装置などの役物電気部品を制御する制御基板４１と、該制御基板４１を収納する制御基板収納部材４２とを含んでいる。役物制御ユニット２０の上部には制御基板４１の出入力部であるコネクタ部５１が配置されており、その周囲は制御基板収納部材４２を構成する上蓋部材４３によって覆われている。上蓋部材４３は、本来、露出した制御基板４１を覆い隠し、これにより制御回路の一部を断線したり不正な配線等を行う不正行為を未然に防止するものである。
【００１３】
導電性部材３は、役物制御ユニット２０の基端側面（裏機構盤６側の面）と概略同形同寸法に成形した大部分が板状の金属製部材であり、この外周縁近傍に適宜配置された複数の舌片２２の孔部にそれぞれ取付部材２１を遊嵌し、この取付部材２１により裏機構盤６に一体成型された柱状の取付台座２３に着脱可能に取り付けられる。本実施形態では、導電性部材３の左右各１箇所と下部右寄り１箇所の合計３箇所に舌片３ａが一体成型されており、それぞれに相当する箇所に裏機構盤６の取付台座２３が形成されている。
【００１４】
本実施形態の取付部材２１は、図３に示すように、頭部２１ａから伸びる軸の先端側に挿入端部２１ｂが形成され、ワンタッチの簡単な手作業で止着が可能な取付具である。即ち、この取付部材２１は、前記取付ベースの先端面の装着孔に挿入端部２１ｂを挿入して頭部２１ａを手で押込むと、挿入端部２１ｂが拡径して前記装着孔の開口縁に係止し、容易に離脱しない状態に変換するものであり、逆に頭部２１ａを手前に引っ張ると挿入端部２１ｂが縮径するので、挿入端部２１ｂを装着孔から容易に引き抜いて取り外すことができる。
【００１５】
そして、導電性部材３の大部分は板状の金属部材によって形成されているが、その周縁部には背面側（上蓋部材４３側）へ起立した起立壁３ｂが一体成型されている。本実施形態では、導電性部材３の両側縁部にのみ起立壁３ｂが形成されているが、導電性部材３の上下縁部を含む周縁部全体に形成してもよい。このように導電性部材３の両側縁部に起立壁３ｂを形成したので、導電性部材３に高い強度を持たせることができる。
なお、導電性部材３は金属製のものに限らず、導電性を有するものであればよく、例えばカーボン等を含有した樹脂製であってもよい。
【００１６】
制御基板収納部材４２は、制御基板４１を取付可能な取付ベース４４と、この取付ベース４４と合わさって制御基板４１を覆う上蓋部材４３とからなる。この取付ベース４４は大部分が板状の合成樹脂部材であり、その両端縁部には上蓋部材４３側へ起立し、制御基板４１を載置する支持壁４５が一体成型されている。この取付ベース４４に形成された支持壁４５には、制御基板４１を載置する載置部４５ａと、導電性部材３の起立壁３ｂを収容する収容部４５ｂを形成するに要するギャップを確保するための段差４５ｃが断面クランク状に形成されている。すなわち、当該支持壁４５の段差４５ｃにおいて、その内側に制御基板４１を載置する載置部４５ａが形成され、その外側に導電性部材３の起立壁３ｂを収容する収容部４５ｂが形成されている。このように取付ベース４４の起立した支持壁４５に、制御基板４１を載置する載置部４５ａと、導電性部材３の起立壁３ｂを収容する収容部４５ｂとを兼ね備えた段差４５ｃを形成しているので、この支持壁４５の段差４５ｃにより制御基板４１を確実に支持することができ、且つ導電性部材３の起立壁３ｂを収容して、この起立壁３ｂに配線等が引っ掛かるのを防止することができる。
【００１７】
導電性部材３を役物制御ユニット２０に取り付ける際には、制御基板収納部材４２を構成する上蓋部材４３の周縁部４３ａにより、導電性部材３の起立壁３ｂが囲繞され、取付ベース４４の支持壁４５及び上蓋部材４３の周縁部４３ａが導電性部材３の起立壁３ｂを収容する収容部４５ｂとして機能する凹室部４６を区画形成している。すなわち、取付ベース４４の支持壁４５及び上蓋部材４３の基端周縁部４３ａによって区画形成された凹室部４６に、導電性部材３の起立壁３ｂが基端側から係合することになる。このように凹室部４６内に導電性部材３の起立壁３ｂを収容しているので、導電性部材３の起立壁３ｂは取付ベース４４の支持壁４５と上蓋部材４３の周縁部４３ａとによって完全に隔離され、この起立壁３ｂに配線等が引っ掛かるのを確実に防止することができる。
【００１８】
また、導電性部材３は、制御基板４１のＧＮＤと導通可能に設けられている。具体的には、図５に示すように、制御基板収納部材４２の底面を構成する取付ベース４４には、円筒状の柱部材を内部に向けて立設することにより取付ベース４４の内外を連通する連通部４７を形成し、この連通部４７内に、軸方向に貫通する雌ネジ孔３４を有する金属製の導通補助部材３５を挿嵌して、制御基板４１のＧＮＤ部の開口部から挿入した雄ネジ３６等の先端雄ネジ部分を上記雌ネジ孔３４内に締め込んで止着することによってＧＮＤと導通補助部材３５を導通させて、連通部４７の外側開口部分より導通補助部材３５の一端を外部に臨ませ、しかも本実施形態では導通補助部材３５の一端の端面が取付ベース４４の裏面よりも僅かに突出するように構成してある。
したがって、取付ベース４４の裏面から僅かに突出した導通補助部材３５の一端が導電性部材３に圧接して電気的に導通する。このため、制御基板４１のＧＮＤ面積が導電性部材３の面積分拡張したことになり、ノイズ等の電気的障害に強くなる。
【００１９】
また、上蓋部材４３の少なくとも上面の一部は、防護蓋部材４８によって覆われている。本実施形態では、役物制御ユニット２０の上部には制御基板４１の出入力部であるコネクタ部５１が配置されており、その周囲は制御基板収納部材４２を構成する上蓋部材４３によって覆われており、防護蓋部材４８は、上蓋部材４３のコネクタ領域以外の下部上面を覆うように設けられている。防護蓋部材４８は、図６及び図７に示すように、この防護蓋部材４８と上蓋部材４３とをかしめ部材６１によりかしめることにより、固定されている。なお、図６（ａ）はかしめ部材６１の固定前の状態を示す図２のＤ線矢視断面図、（ｂ）はかしめ部材６１の固定状態を示す図２のＤ線矢視断面図である。また、図７（ａ）はかしめ部材６１の固定前の状態を示す図２のＣ線矢視断面図、（ｂ）はかしめ部材６１の固定状態を示す図２のＣ線矢視断面図である。
【００２０】
このかしめ部材６１は、図２において、防護蓋部材４８の左右各４箇所のかしめ部６０に装着される。かしめ部６０は矩形凹部として形成され、このかしめ部６０には、防護蓋部材４８の内部に臨ませて、図７において左右に弾力性を有する一対の爪部材６２，６２が形成されている。爪部材６２の爪先端部６２ａは、相対向するように内方へ屈曲している。そして、かしめ部６０の底部には、図６に示すように、かしめ部材６１を挿通させる開口部６３が形成されている。一方、上蓋部材４３の上面には、かしめ部材６１を装着する矩形孔６４が形成されている。
【００２１】
また、かしめ部材６１は、一対の脚部６５，６５を有する概ねＴ字状の部材であり、これら脚部６５，６５は頭部６６、第１連結部６７ａ及び第２連結部６７ｂによって連結されており、その先端部には掛部６８が外方へ張り出すように形成されている。かしめ部材６１の脚部６５，６５の先端掛部６８及び第１連結部６７ａの両端部は楔状に形成されている。
【００２２】
防護蓋部材４８のかしめ部６０にかしめ部材６１を圧入すると、かしめ部材６１の脚部６５，６５の先端掛部６８が上蓋部材４３の上面に形成された矩形孔６４に係合するとともに、かしめ部６０の爪部材６２，６２の爪先端部６２ａがかしめ部材６１の脚部６５，６５の間の空間部６９、すなわち、頭部６６と第１連結部材６７ａとの間の空間部６９に入り込む。したがって、かしめ部材６１の頭部６６がかしめ部６０の爪部材６２，６２の爪先端部６２ａによって支持されるとともに、かしめ部材６１の脚部６５，６５の先端掛部６８が上蓋部材４３の矩形孔６４内に係合されるので、かしめ部材６１により防護蓋部材４８と上蓋部材４３とが強固に連結されることになる。したがって、かしめ部材６１の脚部６５，６５を切断するなどして破損させない限り防護蓋部材４８を開放することができず、制御基板収納部材４２によって覆われた制御基板４１を確実に防護することができ、不正行為の介入を阻止することができる。
【００２３】
本実施形態では、図２において、防護蓋部材４８の左側４箇所のかしめ部６０のいずれか１箇所にかしめ部材６１をかしめ固定するとともに、右側４箇所のかしめ部６０のいずれか１箇所にかしめ部材６１をかしめ固定するものである。このように防護蓋部材４８にかしめ部６０が複数形成されているので、複数回に亘る検査等に対応させることができる。
なお、かしめ部６０及びかしめ部材６１は、切断するなど破損しない限り防護蓋部材４８を開くことができない機能を備えていればどのような構成でもよい。
【００２４】
さらに、上蓋部材４３と取付ベース４４とは係合部材７１により係合され、この係合部材７１は防護蓋部材４８によって覆われている。本実施形態では、この係合部材７１としてネジを採用している。図２に示すように、上蓋部材４３のコネクタ領域以外の部分の四方にはネジ孔の開孔された舌片４３ｂが形成されており、取付ベース４４の相当部位にはネジ孔の開孔された柱状台座（図示せず）が形成されている。したがって、上蓋部材４３の舌片４３ｂにネジ７１を挿通させて、取付ベース４４の柱状台座に螺合することにより、上蓋部材４３と取付ベース４４とを係合することができる。このネジ７１の頭部は、図２に示すように、防護蓋部材４８の周縁部によって、約半分程度覆われているので、防護蓋部材４８を取り外さなければ、ネジ７１の頭部にドライバを装着することができない。したがって、かしめ部材６１を破損させて防護蓋部材４８を開放しなければ、上蓋部材４３と取付ベース４４とを係合するネジ７１を外すことができず、制御基板収納部材４２によって覆われた制御基板４１を更に確実に防護することができる。
なお、上蓋部材４３及び防護蓋部材４８内には、適宜板状または柱状の補強壁７０が一体成型されており、これにより役物制御ユニット２０の強度を増大させることができる。
【００２５】
図４は、制御ユニット及び導電性部材の取付構造における第２実施形態を示す図２のＡ線矢視断面図である。第１実施形態では、取付ベース４４の支持壁４５及び上蓋部材４３の周縁部４３ａによって、導電性部材３の起立壁３ｂを収容する凹室部４６を収容部として区画形成していたが、第２実施形態では、特に取付ベース４４の支持壁４５のみにより導電性部材３の起立壁３ｂを収容する凹室部４６を区画形成している。具体的には、取付ベース４４は合成樹脂部材により形成され、その側縁部は背面側へ起立して、制御基板４１を載置する支持壁４５が一体成型され、この支持壁４５の先端部分に外側に折り返した折返し部４５′を形成し、該折返し部４５′と支持壁４５との間に、前記導電性部材３の起立壁３ｂの少なくとも先端縁を収容する収容部として凹室部４６を区画形成している。すなわち、取付ベース４４の両側縁部には、概ね逆Ｕ字状を呈する支持壁４５が一体成型され、その上端部には隆起部４５ｄが一体成型されている。そして、この隆起部４５ｄにより、取付ベース４４の支持壁４５には、隆起部４５ｄの内側に制御基板４１を載置する基板載置部４５ｅと、その外側に上蓋部材４３の周縁部４３ａを載置する上蓋載置部４５ｇとを有する段差４５ｆが形成されている。
【００２６】
このように取付ベース４４の側縁部に背面側へ起立し、制御基板４１を載置する支持壁４５を形成し、この支持壁４５の先端部分が外側に折り返されて、導電性部材３の起立壁３ｂを収容する収容部として機能する凹室部４６を区画形成しているので、導電性部材３の起立壁３ｂは支持壁４５の折り返し部分によって完全に隔離され、この起立壁３ｂに配線等が引っ掛かるのを確実に防止することができる。
【００２７】
また、前記した各実施の形態ではパチンコ機１を例に挙げて説明したが、本発明はパチンコ機１に限らず、アレンジボール機やスロットマシン等にも適用可能である。
【００２８】
また、今回開示した実施の形態はすべての点で例示であって制限的なものではないと考えるべきである。本発明の範囲は、前記した説明ではなくて特許請求の範囲によって示され、特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれることが意図される。
【００２９】
【発明の効果】
以上説明したように本発明は以下の効果を奏する。
すなわち、取付ベースの周縁部には上蓋部材側へ起立する支持壁を形成し、該支持壁の先端部分に外側に折り返した折返し部を形成して概ね逆Ｕ字状を呈し、該折返し部と前記支持壁との間に凹室部を区画形成し、前記支持壁の上端部には、隆起部を設け、該隆起部の内側に前記制御基板を載置する基板載置部を形成するとともに、前記隆起部の外側に前記上蓋部材の周縁部を載置する上蓋載置部を形成し、前記導電性部材の周縁部には、前記上蓋部材側へ起立する起立壁を形成し、該起立壁を前記凹室部に収容したので、導電性部材の起立壁を支持壁の折返し部によって覆い、起立壁に配線等が引っ掛かるのを防止することができる。
