Description

【０００１】
【発明の属する技術分野】
本発明は、基板となる板部材の前後面に遊技部品が取り付けられて構成される遊技盤の遊技部品取付構造に関する。
【０００２】
【従来の技術】
上記のような遊技盤を備える遊技機として、パチンコ機やアレンジボール機、雀球機などが広く知られている。この種の遊技機の代表例とされるパチンコ機では、前面に遊技領域を有する遊技盤が前枠上部に立設姿勢で収容保持され、この遊技盤に遊技球を打ち出してゲームを行うようになっている。遊技盤は、所定板厚の積層合板の表面にセルを貼り付けた化粧板（一般的に「ベニヤ」と称される）を基板とし、その前面側および後面側にそれぞれ遊技部品が取り付けられて構成される。
【０００３】
前面側遊技部品としては、それぞれ半円弧状に形成された内レールおよび外レール、これらの案内レールに囲まれた遊技領域の内側に取り付けられた多数本の遊技釘、風車、電動チューリップや大入賞口等の入賞具、画像表示装置の飾り枠、遊技領域の外側に取り付けられたレール飾りなどがあり、これらの各遊技部品が所定のゲージ設定に基づいて取り付けられている。また後面側遊技部品としては、画像表示装置の表示パネルや表示パネルを駆動する画像表示基板、化粧板の裏面側に排出されたアウト球およびセーフ球を案内する上下の球寄せカバーなどがある。遊技盤は、化粧板をルータ加工して入賞具やアウト口、装飾ランプ、画像表示装置などの取付孔を形成させた後、前面側遊技部品の取り付け、後面側遊技部品の取り付け、所要の電装作業を行って形成される。
【０００４】
ここで、前面側遊技部品と後面側遊技部品とは、化粧板を挟んで前後に整合して取り付ける必要がある。このため、従来では化粧板の一部に表裏共通する原点を定め、この原点を基準とした位置決め部を各遊技部品に対応して化粧板の前面および後面にそれぞれ形成するとともに、遊技部品側に位置決め部と係脱自在な被位置決め部を形成し、遊技部品側の被位置決め部を化粧板側の位置決め部に係合させて取り付けることにより前後の遊技部品の整合を確保していた。例えば、前面側遊技部品であるレール飾りでは、化粧板前面の所定位置に位置決め用のピン係合穴を穿設するとともに、レール飾りの背面側に後方に突出する位置決めピンを形成し、この位置決めピンをピン係合穴に嵌合させて位置決めを行っていた。また後面側遊技部品である球寄せカバーについても同様であり、化粧板後面の所定位置に位置決め用のピン係合穴を穿設するとともに、球寄せカバーの前面側に前方に突出する位置決めピンを形成し、この位置決めピンをピン係合穴に嵌合させて球寄せカバーの位置決めを行い、これによって前面側遊技部品との整合を図っていた。
【０００５】
また、例えば、後面側遊技部品である球寄せカバーについて、弾性変形可能な固定具を化粧板の後面に４カ所程度ねじ止めして配設する一方、球寄せカバーの四隅に固定具と嵌脱自在な円筒状の開孔を形成し、この開孔を固定具に嵌合させて球寄せカバーを取り付けることで、球寄せカバーの着脱を容易化した取付構造が考案されている（例えば、特許文献１を参照）。

【発明が解決しようとする課題】
しかしながら、上記のような位置決めピンとピン係合穴との係合を利用した遊技部品の取付構造では、化粧板の前後面にそれぞれ遊技部品の取付数に応じたピン係合穴を穿設する必要があり、その穴数に応じた加工工数や検査工数、加工工具の保守点検工数等がかかるという問題があった。また、化粧板に形成されるこれらのピン係合穴は一般に小径であるうえ、遊技部品取付用のネジを案内するネジ導入穴と穴径および配設位置が近く、遊技部品が誤った位置に取り付けられてしまう場合があるという問題があった。さらに、例えば特許文献に記載されたような取付構造では、上記問題に加えて、部品点数や組み付け工数が増大し、製品コストが上昇してしまうという問題があった。
【０００８】
本発明はこのような事情に鑑みて成されたものであり、簡明な構成で上記諸問題を解決可能な遊技部品取付構造を提供することを目的とする。
【０００９】
【課題を解決するための手段】
上記目的達成のため、本発明は、基板となる板部材（例えば、実施形態における化粧板２１）と、この板部材の前面側に取り付けられた前面側遊技部品と、板部材の後面側に取り付けられた後面側遊技部品とを有する遊技盤の遊技部品取付構造である。その上で、本発明の遊技部品取付構造は、前面側遊技部品（例えば、実施形態におけるレール飾り２８）の後面側に後方に突出する円筒状の係合軸が設けられるとともに、当該係合軸の後端部に、前面側遊技部品と後面側遊技部品とを連結する掛止ネジが軸線に沿って螺着されて掛止ネジの頭部が後方に突出して配設され、板部材には係合軸を前面側から受容し係合軸の外周面と係合して前面側遊技部品を板部材の板面に沿った盤面上の所定位置に位置決めするとともに、受容した係合軸の後端に形成された係合部を板部材の後面側に露出させる係合部受容孔が板部材の前後を貫通して形成され、後面側遊技部品（例えば、実施形態における球寄せカバー２９）の前面側には係合部と嵌脱自在な係合受け部が設けられて当該係合受け部に、掛止ネジの頭部を前後に挿通させる頭部挿通孔が形成されるとともに、掛止ネジの頭部を後面側に挿通させた状態で掛止ネジの軸部と係脱可能な係止溝を有するロックレバーが上下揺動可能に設けられ、板部材の前面側から係合部受容孔に係合軸を挿入して係合軸を挿通させることにより係合軸の外周面が係合部受容孔の内周面と係合して前面側遊技部品が板部材の前面側の所定位置に位置決めされ、板部材の後面側に露出した前面側遊技部品の係合部に板部材の後面側から係合受け部を嵌合させることにより前面側遊技部品及び後面側遊技部品が板部材の前面側及び後面側で所定位置に位置決めされ、係合受け部の後面側に突出した掛止ネジの座面と係合受け部の後面との間にロックレバーを差し込んで係止溝を掛止ネジの軸部に係合させることにより前面側遊技部品及び後面側遊技部品が位置決めされた状態で固定されるように構成される。
【００１０】
このような構成の遊技部品取付構造では、板部材に係合軸を前面側から受容して前面側遊技部品を板部材の板面に沿った盤面上の所定位置に位置決めするとともに、受容した係合軸部後端の係合部を後面側に露出させる係合部受容孔が板部材の前後を貫通して形成されており、板部材の前面側から係合部受容孔に係合軸を挿入して板部材の後面側に露出した前面側遊技部品の係合部に、後面側遊技部品の係合受け部を嵌合させることによって前面側遊技部品及び後面側遊技部品が板部材の前面側及び後面側で位置決めされる。このため、板部材の後面側には後面側遊技部品を位置決めするための構造（例えば従来技術における位置決め係合穴等）を設ける必要がなく、その数量に応じた加工工数や検査工数、加工工具の保守点検工数等を削減することができる。
【００１１】
また、板部材に形成された係合部受容孔に前面側遊技部品の係合軸を挿通させることにより係合軸の外周面が係合部受容孔の内周面と係合して前面側遊技部品が位置決めされ、板部材の後面側に露出した係合部に後面側遊技部品の係合受け部を係合させることで後面側遊技部品が直接位置決めされる構成のため、前後の遊技部品を高精度に整合させて取り付けることができるうえ、後面側遊技部品を誤った位置に位置決めして取り付けるような事態も生じ得ない。さらに、このような係合部が前面側遊技部品に設けられているため、前述した固定部材を用いた取付構造のように部品点数や組み付け工数を増大させることもない。
さらに、係合受け部に設けられたロックレバーを揺動させて係止溝を掛止ネジの軸部に係合させることで前後の側遊技部品が板部材の所定位置に位置決めされた状態で固定されるため、作業者が必要に応じて後面側遊技部品を容易に着脱することができる。
なお、本発明において、係合軸、係合部受容孔及び係合受け部が、前面側遊技部品、板部材及び後面側遊技部品の各対応位置に複数組設けられ、前面側遊技部品及び後面側遊技部品が板部材に複数個所で位置決め固定されるように構成することが好ましい。
【００１２】
【発明の実施の形態】
以下、本発明の好ましい実施形態について添付図面を参照しながら説明する。本発明に係る遊技部品取付構造を備えた遊技機の一例として、図１にパチンコ機ＰＭの正面図を示し、図２に外枠を取り外して裏セット盤を開放した状態におけるパチンコ機ＰＭの背面図を示しており、まずこの両図面を参照してパチンコ機ＰＭの概要について説明する。
【００１３】
パチンコ機ＰＭは、外郭方形枠サイズに構成されて縦向きの固定保持枠をなす外枠１の開口前面に、これに合わせた方形枠サイズに構成されて開閉搭載用の前枠２が互いの正面左側に配設されたヒンジ機構３ａ，３ｂで横開き開閉および着脱が可能に取り付けられ、正面右側に設けられた施錠装置４を利用して常には外枠１と係合された閉鎖状態に保持される。
【００１４】
前枠２の前面上部には、前枠２の前面域に合わせた方形状のガラス扉５および上球皿６が正面左側に設けられたヒンジ機構で横開き開閉および着脱が可能に取り付けられ、正面右側に設けられた施錠装置４および球皿施錠装置を利用して前枠２の前面を覆う閉鎖状態に保持される。前枠２の前面下部には、下球皿７が設けられ、この下球皿７と並んで遊技球の発射操作を行う発射ハンドル８が取り付けられている。
【００１５】
前枠２の上部には、ガラス扉５の背後に位置して遊技盤２０を立設姿勢で収容する収容枠１０が一体に成型され、この収容枠１０に設けられたクランプレバー１２，１２…を利用して遊技盤２０が着脱可能に収容保持され、常には閉鎖保持されるガラス扉５にその前面の遊技領域ＰＡを臨ませている。
【００１６】
前枠２の前面側には上球皿６の背後に位置して遊技盤２０と上下に整合し得る遊技補助盤が形成され、遊技球を遊技盤２０に向けて発射する遊技球発射装置９や、ファール球を回収して下球皿７に流下させるファール球回収通路、遊技の展開状態に応じて効果音を発生させるスピーカなどが設けられている。
【００１７】
前枠２の裏側には裏セット盤３０がヒンジ機構３１，３１を利用して着脱および横開き開閉可能に取り付けられている。裏セット盤３０には、遊技球を貯留する球貯留タンクや、所定の入賞状態に基づいて遊技球を払い出す球払出装置、球払出装置から払い出された遊技球を上下の球皿６，７に導く払出通路３４などの賞球機構、および遊技盤２０から裏面側に排出されたアウト球およびセーフ球（これらをまとめて「遊技済み球」という）を集合させて遊技施設側の回収バケットに流下させる遊技済み球排出通路３６が設けられている。裏セット盤３０の裏面側には、これらの球通路の背後に位置して電源基盤や主制御基板、払出制御基板などの各種回路基盤が取り付けられ、これらの回路基板と電気・電子部品とが配線接続されて遊技可能に構成される。
【００１８】
パチンコ機ＰＭは、ガラス扉５、上球皿６などが閉鎖施錠された状態で遊技に供され、上球皿６に遊技球を貯留させて発射ハンドル８を回動操作することにより遊技が開始される。発射ハンドル８が回動操作されると、上球皿６に貯留された遊技球が１球ずつ遊技球発射装置９に送り出され、揺動駆動されるハンマにより遊技領域ＰＡに打ち出されてパチンコゲームが展開される。
【００１９】
このように概要構成されるパチンコ機ＰＭにあって、遊技盤２０は、遊技盤単体の正面図および背面図をそれぞれ図３(ａ)および(ｂ)に示すように、基板となる化粧板２１と、この化粧板２１の前面側に取り付けられた前面側遊技部品と、化粧板２１の後面側に取り付けられた後面側遊技部品とを有して構成される。
【００２０】
化粧板２１は、板厚19mm程度の積層合板の表面に、このパチンコ機ＰＭのテーマに合致した意匠を施したセル（絵柄シート）を貼り付け、多軸ボール盤による基準孔や位置決め孔の穿設、ゲージプレス機による遊技釘や役物取付ネジ等のガイド穴の形成、ＮＣルータ加工機による外形加工および画像表示装置取付孔、入賞具取付孔、サイドランプ取付孔、アウト口などの穿設加工を行って形成される。
【００２１】
セルが貼り付けられた化粧板２１の前面側に取り付けられる前面側遊技部品としては、内外の案内レール２２（内レール２２ａおよび外レール２２ｂ）、これらの案内レール２２に囲まれた略円形の遊技領域ＰＡの内側に取り付けられた多数本の遊技釘および風車、電動チューリップや大入賞口等の各種入賞具２４、画像表示装置２５の周囲を飾る中央飾り２５ｓ、左右のサイドランプ２６，２６、アウト口２７の周囲を飾るアウト口飾り２７ｓ、遊技領域ＰＡの外側に取り付けられたレール飾り２８などがある。
【００２２】
前面側遊技部品は、内外の案内レール２２、遊技釘、風車等が自動打ち込み機により打ち込み固定された後、入賞具２４、中央飾り２５ｓ、サイドランプ２６、アウト口飾り２７ｓ、レール飾り２８などが化粧板２１に穿設された取付孔に装着され、各々ネジ固定されて取り付けられた後、次工程の後面側遊技部品の取付が行われる。
【００２３】
一方、化粧板２１の後面側に取り付けられる後面側遊技部品としては、画像表示装置２５における表示パネルや、この表示パネルを駆動する画像表示基板２５ｐ、各入賞具２４を通って化粧板２１の後面側に排出されたセーフ球、およびアウト口２７を通って化粧板２１の後面側に排出されたアウト球を化粧板２１の背面に沿って下方に案内し、裏セット盤３０の遊技済み球排出通路３６に流下させる球寄せカバー２９、各種電気配線を中継する中継基板やホールコンピュータ用の中継基板を取り付ける基板取付台座（本例では球寄せカバー２９として兼用）などがあり、前面側遊技部品の取り付けに続いて各遊技部品が取り付けられ、遊技盤単体の完成検査の後、収容枠１０に取り付けられる。
【００２４】
さて、このような構成の遊技盤２０にあって、各図には前面側遊技部品であるレール飾り２８および後面側遊技部品である球寄せカバー２９に本発明に係る遊技部品取付構造を適用した例を示しており、以下、図４〜図７の各図を参照して第１実施例の遊技部品取付構造１００について説明する。ここで、図４は遊技盤２０の背面左上方の遊技部品取付構造１００を示す背面図、図５はこの遊技部品取付構造１００の分解斜視図、図６は遊技部品取付構造１００における係合部の背面図(ａ)，係合受け部の断面図(ｂ)，および係合受け部の正面図(ｃ)、図７はレール飾り２８と球寄せカバー２９とを係合させる前の遊技部品取付構造１００の平断面図(ａ)，およびこれらを係合させて取り付けた後の遊技部品取付構造１００の平断面図(ｂ)である。
【００２５】
この遊技部品取付構造１００は、後端に係合部１１５を有しレール飾り２８に後方に突出成型された係合軸１１０と、化粧板２１を前後に貫通して形成された係合部受容孔１２０と、係合部１１５と係脱自在な係合受け部１３５を有して球寄せカバー２９に形成された係合フランジ１３０等からなり、係合軸１１０を化粧板の前面側から係合部受容孔１２０に挿通させてレール飾り２８を取り付け、化粧板２１の後面側に突出した係合部１１５に係合受け部１３５を係合させることによって、球寄せカバー２９が化粧板２１の後面側で位置決めされるように構成される。遊技部品取付構造１００は、レール飾り２８と球寄せカバー２９とが化粧板２１を挟んで前後に重複する適宜な位置に設けられ、本実施例では、背面視における遊技盤２０の左側上下の２カ所に設けた例を示す。
【００２６】
係合軸１１０は円筒ボスの中心軸に沿ってスリ割りを入れ、左右方向に弾性を持たせた２分割スリーブ状の軸部１１１と、この軸部１１１の後方に化粧板２１の板厚に合わせて左右に張出成型された楔状のロック爪１１２、軸部１１１の後端(先端)に形成された係合部１１５、軸部１１１の中心に形成されたネジ受容部１１６などからなり、レール飾り２８のベース部材２８ｂに後方に突出して一体成型される。係合軸１１０の先端角部は斜めに面取りされて挿入案内面が形成されている。
【００２７】
係合部受容孔１２０は、係合軸１１０の配設位置および軸部１１１の外形に合わせて化粧板２１を前後に貫通して形成され、遊技盤全体の基準位置を定める基準孔とともに多軸ボール盤によって穿設される。係合軸１１０を係合部受容孔１２０に挿通させると、軸部１１１の左右の外周面が係合部受容孔１２０の内面と係合してレール飾り２８が盤面上の所定位置に位置決めされ、左右のロック爪１１２が化粧板２１の後面側で開くように係合してレール飾り２８が当該位置にロック保持される。そして、軸部１１１の後端の係合部１１５がこのように位置決めされた所定位置で後方に突出して配設される。
【００２８】
係合フランジ１３０は、係合軸側の係合部１１５と係脱自在な係合受け部１３５、係合受け部１３５の周囲を取り囲んで形成された補強リブ１３２，１３３、取付ネジ１３８の頭部高さよりも幾分深めに前方にザグリ形成された座面１３４、係合受け部１３５の軸心に位置して座面１３４を前後に貫通するネジ挿通孔１３６等からなり、球寄せカバー２９に一体成型で形成されている。
【００２９】
係合受け部１３５の内径ｄは、係合部１１５の外径Ｄと同一またはわずかに小径に形成される一方、後端側の内周角部が斜めに面取りされて導入面が形成されており、係合軸１１０の先端角部の挿入案内面と相まって滑らかに嵌合し得るようになっている。また係合受け部１３５の高さは、係合部１１５に係合受け部１３５を嵌合させて球寄せカバー２９の前端面を化粧板２１の後面に密着させたときに、ロック爪１１２の案内面が係合受け部１３５に当接せず、係合部１１５の後端面（係合軸１１０の後端面）と係合受け部１３５の底面とが当接しないように設定されている。
【００３０】
このように形成される遊技部品取付構造１００では、まずレール飾り２８を化粧板２１の前面側から取着する。このときレール飾り２８の係合軸１１０を化粧板２１の前面側から係合部受容孔１２０に挿通させると、左右のロック爪１１２が係合部受容孔の入り口周面と係合し、このロック爪の斜面状の案内面および軸部に形成されたスリ割りの作用によって左右の軸部１１１が内径側に弾性変形し係合部受容孔１２０内に進入する。
【００３１】
レール飾り２８のベース部２８ｂが化粧板２１の前面に当接する近傍位置まで係合軸１１０が挿入されると、この化粧板２１の板厚に合わせて形成されたロック爪１１２が化粧板２１の後面側で開くように係合し、軸部１１１の外周面が係合部受容孔１２０の内面と係合して、レール飾り２８が化粧板２１の所定位置に位置決めされるとともに、ロック爪１１２の作用により当該位置にロックされ仮支持される。
【００３２】
一方、化粧板２１の後面側では、係合軸先端の係合部１１５が上記位置決めされた所定位置で化粧板２１の裏面から後方に突出して配設されている。そこで、化粧板２１の裏面側から球寄せカバー２９を覆い被せ、後方に突出配設されている係合部１１５に係合受け部１３５を嵌合させる。これにより球寄せカバー２９が化粧板２１の後面側で位置決めされる。そして、係合フランジ１３０の後方から取付ネジ１３８をネジ挿通孔１３６に挿入し、係合軸１１０のネジ受容孔１１６に螺合させて締め込むことで、球寄せカバー２９が化粧板の後面側に取り付けられる。
【００３３】
ここで、係合軸１１０における係合部１１５の外形Ｄと、係合フランジ１３０における係合受け部１３５の内径ｄとの関係では、係合部１１５の外径Ｄが係合受け部１３５の内径ｄよりも大きめに（すなわち締まりばめ傾向に）形成され、係合部１１５の突出高さと係合受け部１３５の深さとの関係では、係合部１１５の後端面と係合受け部１３５の底面とが当接しないように設定されている。
【００３４】
このため、係合受け部１３５の開口端部を係合部１１５の先端部にあてがって前方に押圧すると、係合受け部１３５の前端部に形成された導入面と係合部１１５の先端部に形成された挿入案内面とが係合して軸部１１１を軸心方向に押圧し、軸部１１１に形成されたスリ割りの作用によって左右の軸部１１１が縮径方向に弾性変形して、係合受け部１３５と係合部１１５とが滑らかに嵌合する。そこで、係合フランジ１３０の後方からネジ挿通孔１３６に取付ネジ１３８を装着してネジ受容部１１６に締め込むことで、レール飾り２８と球寄せカバー２９とが化粧板２１を挟み込むようにして緊密に締結される。これにより、これらの遊技部品が振動したりガタツキを生じたりすることがない。
【００３５】
従って、このような遊技部品取付構造１００によれば、球寄せカバー２９を位置決めするための構造を化粧板２１の後面側に形成せずに球寄せカバー２９を位置決めして固定することができ、化粧板２１の加工工数や検査工数等を削減することができる。また、レール飾り２８に形成した係合軸１１０を利用してレール飾り２８と球寄せカバー２９の両遊技部品を直接位置決めする構成のため、部品点数や加工工数を低減した簡明な構成でありながら、前後の遊技部品を高精度に整合させて取り付けることができ、前後の遊技部品が過誤によって不適切な位置に取り付けられるような事態も生じることがない。さらにレール飾り２８はパチンコ機の機種が異なっても共通部品として使用される遊技部品であり、かつその取付位置も一定であるため、係合軸を形成するのに好適な前面側遊技部品である。
【００３６】
次に、第２実施例の遊技部品取付構造２００について、図８〜図１０の各図を参照して説明する。この遊技部品取付構造２００は、第１実施例で説明した遊技部品取付構造１００と同様に、前側遊技部品であるレール飾り２８および後面側遊技部品である球寄せカバー２９に本発明に係る遊技部品取付構造を適用したものである。なお、図８は遊技盤２０における背面左上の遊技部品取付構造２００を示す背面図、図９はこの遊技部品取付構造２００の分解斜視図、図１０はレール飾り２８と球寄せカバー２９とを係合させて取り付けた後の遊技部品取付構造２００の平断面図である。
【００３７】
この遊技部品取付構造２００は、後端に係合部２１５を有しレール飾り２８に後方に突出成型された係合軸２１０と、化粧板２１を前後に貫通して形成された係合部受容孔２２０、係合部２１５と係脱自在な係合受け部２３５を有して球寄せカバー２９に形成された係合フランジ２３０、および係止溝を有して係合軸２１０と直交する面内に揺動可能に枢結されたロックレバー２４０等からなり、係合軸２１０を化粧板の前面側から係合部受容孔２２０に挿通させてレール飾り２８を取り付け、化粧板２１の後面側に突出した係合部２１５に係合受け部２３５を係合させることによって球寄せカバー２９が化粧板２１の後面側で位置決めされる。そして、ロックレバー２４０を係合軸先端の掛止ネジ２１８に係脱させることで球寄せカバー２９が化粧板２１の後面側に着脱自在に取り付けられる。本実施例では、前述した実施例と同様に、遊技部品取付構造２００を背面視における球寄せカバー２９の左側上下の２カ所に設けた例を示す。
【００３８】
係合軸２１０は緩い先端先細りのテーパ形態で突出成型された円筒ボス状の軸部２１１と、この軸部２１１の後端(先端)に形成された係合部２１５、軸部２１１の中心に形成されたネジ受容部などからなり、レール飾り２８のベース部材２８ｂに後方に突出して一体成型される。係合軸２１０の先端角部は斜めに面取りされて挿入案内面が形成されており、またネジ受容部２１６には予め掛止ネジ２１８が所定高さに螺合されて取り付けられる。
【００３９】
係合部受容孔２２０は、係合軸２１０の配設位置および軸部２１１の基端側の外形に合わせて化粧板２１を前後に貫通して形成され、遊技盤全体の基準位置を定める基準孔とともに多軸ボール盤によって穿設される。このため、係合軸２１０を係合部受容孔２２０に挿通させると、軸部２１１のテーパ状の外周面が係合部受容孔２２０の内面と係合してレール飾り２８が盤面上の所定位置に位置決めされ、弱テーパに形成された軸部２１１の外周面と係合軸受孔２１０の内周面との摩擦係合によりレール飾り２８が当該位置に仮支持される。そして、軸部２１１の後端の係合部２１５および掛止ネジ２１８が位置決めされた所定位置で後方に突出して配設される。
【００４０】
係合フランジ２３０は、係合軸側の係合部２１５と係脱自在な係合受け部２３５、前述した補強リブ１３２，１３３と同様に係合受け部２３５の周囲を取り囲んで立設成型された補強リブ２３２，２３３、ロックレバー２４０を揺動自在に支持するレバー支持部２３１、ロックレバーの操作つまみ部２４６が後方に突出しないように幾分深めにザグリ形成された座面２３４、係合受け部２３５の軸心に位置して座面２３４を前後に貫通するネジ頭部挿通孔２３６等からなり、球寄せカバー２９に一体に形成されている。
【００４１】
係合受け部２３５の内径は、係合部２１５の外径よりもわずかに大きめに形成されるとともに、前端側の内周角部が斜めに面取りされて導入面が形成されており、係合軸２１０先端の挿入案内面と相まって滑らかに嵌合し得るようになっている。また係合受け部２３５の高さは、係合部２１５に係合受け部２３５を嵌合させて球寄せカバー２９の前端面を化粧板２１の後面に密着させたときに、係合部２１５の後端面（係合軸２１０の後端面）と係合受け部２３５の底面とが当接しないように設定されている。
【００４２】
レバー支持部２３１は、左側面側の補強リブ２３２から左外方に延出されるとともに、板状の支持面から後方に突出して円筒状の支持ボス２３１ｂが形成され、この支持ボス２３１ｂの後端に段付き状の後端円筒部が、その中心にネジ受容孔が形成されている。支持ボス２３１ｂの形成高さは、この支持ボスの後端円筒部に次述するロックレバー２４０を嵌合支持させたときのアーム部２４３の前面位置が座面２３４と整合するように設定されている。また、座面２３４に穿設されたネジ頭部挿通孔２３６は掛止ネジ２１８のネジ頭部の外形よりも大きめの内径を有して形成されている。
【００４３】
ロックレバー２４０は、帯板状のアーム部２４３、このアーム部２４３の基端側に成型された軸受部２４１、アーム部２４３の中間に後方に突出成型された操作つまみ部２４６、アーム部２４３の先端側に切り欠き成型されたフック溝２４５等からなり、例えばＡＢＳ樹脂やＰＯＭ等の樹脂材料を用いて射出成型等の成形手段で一体成型される。
【００４４】
軸受部２４１は、中心にショルダネジ２４８の軸部に軸支される軸受孔が形成されるとともに、その前端側にレバー支持部２３１における支持ボス２３１ｂの後端円筒部と嵌合する嵌合穴が形成されており、嵌合穴を後端円筒部に嵌合させて、軸受部２４１の後方から軸受孔を通して支持ボス２３１ｂのネジ受容孔にショルダネジ２４８を螺合締結することにより、ロックレバー２４０がレバー支持部２３１に揺動可能に枢結される。
【００４５】
フック溝２４５は、上記のように揺動可能に枢結されたロックレバー２４０の先端側を座面２３４上に揺動させたときに、フック溝２４５の溝中心がネジ頭部挿通孔２３６の孔中心を通る半径位置に切り欠き成型されており、このネジ頭部挿通孔２３６を通って掛止ネジ２１８が後方に突出配設された状態で、ロックレバー２４０を揺動させたときに、フック溝２４５が掛止ネジ２１８の軸部と係脱可能になっている。
【００４６】
このように形成される遊技部品取付構造２００では、まずレール飾り２８を化粧板２１の前面側から取着する。レール飾り２８の係合軸２１０を化粧板２１の前面側から係合部受容孔２２０に挿通させると、前述した軸部２１１のテーパ面の作用により、レール飾り２８が化粧板２１の所定位置に位置決めされるとともに、軸部２１１の外周面と係合軸受孔２１０の内周面との摩擦係合によりレール飾り２８が当該位置に仮支持される。そこで、このように仮支持されたレール飾り２８を必要に応じてビス止めすることで、レール飾り２８が化粧板２１の前面側に固定される。
【００４７】
一方、化粧板２１の裏面側では軸部後端の係合部２１５が位置決めされた所定位置で後方に突出して配設されている。そこで、化粧板２１の裏面側から球寄せカバー２９を覆い被せ、後方に突出配設されている係合部２１５に係合受け部２３５を嵌合させる。これにより球寄せカバー２９が化粧板２１の後面側で位置決めされる。ここで、係合受け部２３５の内径が係合部２１５の外径よりもわずかに大きめに形成され、また係合受け部２３５の前端部および係合部２１５の先端部にはともに斜面状の導入面および挿入案内面が形成されている。このため、球寄せカバー２９を覆い被せたときに、係合受け部２３５が係合部２１５と滑らかに嵌合して位置決めされる。そして、係合軸２１０に螺合された掛止ネジ２１８の頭部が、掛止フランジ２３０のネジ頭部挿通孔２３６を通って座面２３４よりも後方に突出して配設される。
【００４８】
そこで、操作つまみ部２４６を利用してロックレバー２４０を揺動させ、ロックレバー２４０の先端側を座面２３４上に揺動させてフック溝２４５を掛止ネジ２１８の軸部に係合させる。これによりフック溝２４５の周縁部が座面２３４と掛止ネジ２１８のネジ頭部との間に挟持されるように係合し、レール飾り２８が化粧板２１の後面側に位置決めされて係止保持される。
【００４９】
また、作業者は必要に応じて掛止ネジ２１８を増し締めすることができ、これによりロックレバー２４０を係止状態に固定することも可能である。これにより、化粧板２１をレール飾り２８と球寄せカバー２９とで前後に挟み込むように係合させ、さらに緊密に締結させることができる。なお、フック溝周辺のアーム部の厚さを、フック溝２４５の開口部で薄く、フック溝２４５の溝奥部で厚く形成し、操作つまみ部２４６を押圧して掛止ネジ２１８のネジ頭部と座面２３４との間に滑り込ませて係合させるように構成してもよく、このような構成によれば掛止ネジを増し締め等することなく緊密に締結させることができる。
【００５０】
従って、以上説明したような遊技部品取付構造２００によれば、球寄せカバー２９を位置決めするための構造を化粧板２１の後面側に形成することなく球寄せカバー２９を位置決め固定することができ、化粧板２１の加工工数や検査工数等を削減することができる。また、レール飾り２８に形成した係合軸２１０を利用してレール飾り２８と球寄せカバー２９の両遊技部品を直接位置決めする構成のため、部品点数や加工工数を低減した簡明な構成でありながら、前後の遊技部品を高精度に整合させて取り付けることができ、前後の遊技部品が過誤によって誤った位置に取り付けられるような事態も生じることがない。さらに、本構成の遊技部品取付構造では球寄せカバー２９を係止させるロックレバー２４０が係脱可能に設けられているため、作業者は必要に応じて球寄せカバー２９を容易に着脱することができ、作業性を向上させた遊技機を提供できる。
【００５１】
なお、遊技盤取付構造を形成する前面側遊技部品としてレール飾り２８を、後面側遊技部品として球寄せカバー２９を例示したが、これらの前面側および後面側の遊技部品は他の部品であってもよく、例えば、中央飾り２５ｓやサイドランプ２６等であってもよい。また、前面側遊技部品に形成される係合部は化粧板２１の後面側に露出して配設され後面側遊技部品の係合受け部が係脱可能であればよく、例えば、係合部受容孔１２０，２２０の内部で係合部と係合受け部とが係合するような形態であってもよい。さらに、本実施形態では複数組設けた例として、係合部１１５と係合受け部１３５とを正面向かって右側の上下に２組設けたものを示したが、所定の部位に１組設ける構成としてもよいし３組以上設ける構成としてもよい。
【００５２】
【発明の効果】
以上説明したように、本発明の遊技部品取付構造では、基板となる板部材の前面側に取り付けられる前面側遊技部品に後方に突出する係合軸を設け、板部材には係合軸を前面側から受容し係合軸の外周面と係合して前面側遊技部品を板部材の板面に沿った盤面上の所定位置に位置決めするとともに、受容した係合軸の後端に形成された係合部を板部材の後面側に露出させる係合部受容孔を形成し、後面側遊技部品には係合部と嵌脱自在な係合受け部を設けて、板部材の前面側から係合部受容孔に係合軸を挿入して板部材の後面側に露出した係合部に、後面側遊技部品の係合受け部を嵌合させることにより前面側遊技部品及び後面側遊技部品が板部材の前面側及び後面側で位置決めされるように遊技部品取付構造を構成する。このため、板部材の後面側には後面側遊技部品を位置決めするための構造を穿設する必要がなく、その穴数に応じた加工工数や検査工数、加工工具の保守点検工数等を削減することができる。
【００５３】
また、板部材に形成された係合部受容孔に前面側遊技部品の係合軸を挿通させることにより係合軸の外周面が係合部受容孔の内周面と係合して前面側遊技部品が位置決めされ、板部材の後面側に露出した係合部に後面側遊技部品の係合受け部を係合させることで後面側遊技部品が直接位置決めされる構成のため、前後の遊技部品を高精度に整合させて取り付けることができるうえ、後面側遊技部品を誤った位置に位置決めして取り付けるような事態も生じ得ない。さらに、このような係合部が前面側遊技部品に設けられているため、板部材の裏面に固定部材を取着して構成した遊技部品取付構造のように部品点数や組み付け工数を増大させることもなく、簡明な構成で従来の諸問題を解決し得る遊技部品取付構造を提供することができる。
さらに、係合受け部に設けられたロックレバーを揺動させて掛止ネジの座面と係合受け部の後面との間にロックレバーを差し込み係止溝を掛止ネジの軸部に係合させることにより前面側遊技部品及び後面側遊技部品が板部材の前面側及び後面側の所定位置に位置決めされた状態で固定されるため、作業者が必要に応じて後面側遊技部品を容易に着脱することができ、作業性を向上させた遊技機を提供できる。
