Description

【０００１】
【発明の属する技術分野】
本発明は、パチンコ遊技機やスロットマシンなどの遊技機に取り付けられ、その遊技動作を制御するための基板収納ケースに関するものである。
【０００２】
【従来の技術】
一般に、この種遊技機には所定個所にその遊技動作を制御する回路基板を内装した基板収納ケースが取り付けられる。該基板収納ケースは、遊技機に取り付けられる台板と、該台板の前面に固着されマイクロコンピュータのＣＰＵ，ＲＯＭ等の電子部品が多数装備される回路基板と、前記台板とほぼ同じ大きさからなり回路基板を覆うようにして台板に取り付けられる箱状のカバー体とからなり、これらを重ね合せ更にカバー体に螺子を挿通して締め付けることにより一体に組み付けている。
【０００３】
【発明が解決しようとする課題】
しかしながら、近時パチンコホールにおいて回路基板のＲＯＭを勝手に改造してゲームに賭博性を持たせるといった不正行為が頻発しており、これを防止するため前記台板とカバー体間に跨がるようにして破損し易い封印紙を貼着し、該封印紙が破損していた場合には不正なＲＯＭ交換が行なわれたとみなしていた。ところが、前記封印紙を巧妙に剥がし内部のＲＯＭを交換した後、再度封印紙を元の通りに貼り付けておくといった不正行為が行なわれ、封印紙を見ただけでは前記不正が行なわれたか否かが分らないという課題が生じている。
【０００４】
そこで、このような不正行為ができないようにするめに、例えば特開平６−２６９５３９号公報に開示される基板収納ケースが有る。該基板収納ケースは、箱体と該箱体を覆うカバー体とからなり、箱体の内側壁とカバー体とを外部から解除することができない係止垂下片と係止突起とからなる係止手段で係止するようにしている。これによれば、基板収納ケースの開封は係止垂下片を切断する以外に方法がなく、係止垂下片が切断されていれば不正な処理がなされたことが直ちに分かるようになっている。ただ、一旦係止垂下片を切断した基板収納ケースは再利用することができないという難点が有る。
【０００５】
これに対し、回路基板を収納して密封した基板収納ケースは、ＲＯＭ内容の対比照会検査のため、例えば基板収納ケースを取り付けた遊技機の製造メーカー、さらにパチンコホールでの遊技機の設置時などの検査や故障の際には何れも開封する必要があり、このため前記基板収納ケースに複数回の開封及び密封が可能な構造形態が求められている。
【０００６】
そこで、本発明は上記した課題並びに要望に鑑みてなされたもので、内部に収納された回路基板のＲＯＭを交換して勝手に改造するといったことができず、しかも、複数回の開封及び密封ができて再利用を可能とした遊技機における基板収納ケースを提供することを目的とするものである。
【０００７】
【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は、遊技機の所定個所に取り付けられる台板と、該台板の前面に固着され遊技機の遊技状態を制御する回路基板と、前記台板とほぼ同じ大きさを有し前記回路基板を覆うようにして台板に取り付けられる箱状のカバー体とからなる基板収納ケースにおいて、前記台板にカバー体を取り付けた状態で解除不能となし得る係合手段によって前記カバー体が無用に開封できないようにし、前記係合手段は外部から切離可能にかつ複数設けて構成されている。
【０００８】
このように、前記台板にカバー体を取り付けた状態で解除不能となし得る係合手段によって前記カバー体が無用に開封できないようにしたので、常態では係合手段を解除不能とすることによりカバー体内に回路基板が密封される。これにより、ＲＯＭを交換して改造するという不正行為が防止され、仮に前記係合手段を切離して不正行為を行なえば、その係合手段の切離しにより不正行為が行なわれたことが直ちに分る。
【０００９】
また、遊技機の製造メーカーなど各場所での基板収納ケースにおけるＲＯＭ内容の対比照会検査にあっては、その検査の際にあらかじめ解除不能とした１つの係合手段を切離してカバー体を開けて検査をする。そして、検査後はカバー体を再び取り付け次の係合手段を解除不能とする。このように解除不能となし得る係合手段を複数設けることにより、基板収納ケースの複数回の開封及び密封ができ再利用可能となる。
【００１０】
前記係合手段は、前記台板にカバー体を取り付けた状態でその外周側面に複数設けられる。そして、該各係合手段は、前記台板とカバー体とにそれぞれ外部から切離可能な取付片を介して一体に設けられかつ互いに嵌合する上部半体と下部半体、および該各上・下部半体が互いに嵌合したとき挿通されて両上・下部半体を解除不能となし得る抜脱不能な係合部材とから構成される。
【００１１】
【発明の実施の形態】
以下、本発明に係る遊技機における基板収納ケースの実施の形態を図面と共に説明する。なお、遊技機にはパチンコ遊技機，スロットマシン等が有るが、その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裏面図である。図中、１は機枠であり、該機枠１に装着される前面枠２の裏面に遊技盤取付枠３が固着され、該遊技盤取付枠３に遊技盤４が装着されている。そして、遊技盤取付枠３の一側には遊技盤４の裏面全体を覆う合成樹脂製の機構板５が開閉自在に装着されている。
【００１２】
前記機構板５の裏面にはその上部にパチンコ球を貯留する景品球タンク６，該景品球タンク６から流下するパチンコ球を整列流下させるタンクレール７，またその一側部に該タンクレール７から流下するパチンコ球の球圧を弱めるカーブ樋８，該カーブ樋８からパチンコ球を受け入れる景品球払出装置９，該景品球払出装置９から払い出された所定個数のパチンコ球を誘導する景品球排出樋１０等がそれぞれ配設されている。
【００１３】
また、前記機構板５のほぼ中央に窓口１１が開設され、該窓口１１に臨んで前記遊技盤４の裏面と対応する機構板５の前側に入賞球集合カバー１２が設けられ、該入賞球集合カバー１２の裏面に本発明に係わる基板収納ケース１３が装着されている。なお、１４は遊技盤４面に装着された可変表示装置（図示せず。）の後方部分を覆い保護する保護カバーである。また、前記基板収納ケース１３は入賞球集合カバー１２の裏面に限らず、例えば前面枠２の裏面下部など他の個所に装着しても良い。
【００１４】
前記基板収納ケース１３は、図２及び図３に示すように前記入賞球集合カバー１２の裏面にビス１５により取り付けられる台板１６と、該台板１６の前面に固着されパチンコ遊技機の遊技状態を制御する回路基板１７と、前記台板１６とほぼ同じ大きさからなり回路基板１７を覆うようにして台板１６に取り付けられるカバー体１８とからなる。
【００１５】
前記台板１６は回路基板１７に合致する縦長長方形の金属板１６ａからなり、左右両側端縁に表側へ直角に折れ曲る折り曲げ片部１６ｂ，１６ｂを有する。該金属板１６ａの四隅角部にはねじ孔１９を穿設した突起２０，２０…が設けられている。そして、金属板１６ａの上側端縁の両側に裏側に折れ曲る掛止片２１，２１が突設され、下側端縁には表側へ直角に折れ曲る支持片２２が一体に設けられる。該支持片２２の両側にはねじ孔２３，２３が開設されている。また、前記金属板１６ａの外周縁には適宜位置に取付板部２４，２４…が延設され、該各取付板部２４，２４…に前記入賞球集合カバー１２の裏面に取り付けするためのビス１５，１５…が挿通される透孔２５，２５…が貫設されている。
【００１６】
また、前記回路基板１７は周知のように縦長長方形をなすプリント配線基板よりなり、その上面にＲＯＭ２６ａ，ＣＰＵ２６ｂ及びその他各種の電子部品２７が関連付けられて配置されている。２８，２８…は回路基板１７の一側に複数列設された入出力用コネクターである。また、回路基板１７の四隅角部には前記各突起２０，２０…のねじ孔１９と連通する止着孔２９，２９…が貫設され、該各止着孔２９，２９…にビス３０を挿通して各ねじ孔１９，１９…に螺締することにより回路基板１７が固着される。
【００１７】
更に、前記カバー体１８は透明な合成樹脂製であって、台板１６の金属板１６ａにほぼ対応した大きさからなり、裏面が開放し前記回路基板１７の入出力用コネクター２８，２８…側を残した全面を覆う箱形状を成す。そして、上側壁１８ａの両側下縁に前記掛止片２１，２１に係合する掛止孔３１，３１が開設されている。また、下側壁１８ｂには前記支持片２２と対向位置させて係止凹部３２が設けられている。３３，３３は該係止凹部３２の両側であって下側壁１８ｂに開設されたねじ孔である。なお、前記カバー体１８の前側壁１８ｃには基板収納ケース１３内の熱を放散するためスリット状の放熱孔３４が多数開設されている。
【００１８】
しかして、Ａは前記台体１６にカバー体１８を取り付けた状態で、該カバー体１８が無用に開封できないようにするために設けられた解除不能となし得る係合手段である。該係合手段Ａは図４に示されるように４個設けられ、前記カバー体１８の下側壁１８ｂに固着され、横一列に配設される４個の上部半体３５ａ，３５ｂ，３５ｃ，３５ｄと、前記台板１６の支持板２２に固着され、前記各上部半体３５ａ，３５ｂ，３５ｃ，３５ｄと対向位置して配設される４個の下部半体３６ａ，３６ｂ，３６ｃ，３６ｄと、該各上・下半体３５ａ〜３５ｄ，３６ａ〜３６ｄが互いに嵌合したとき挿通されて両上部半体３５ａ〜３５ｄと下部半体３６ａ〜３６ｄとを解除不能となし得る抜脱不能な４個の係合部材３７ａ，３７ｂ，３７ｃ，３７ｄとから構成されている。前記両上・下半体３５ａ〜３５ｄ，３６ａ〜３６ｄ及び係合部材３７ａ〜３７ｄはいずれも合成樹脂製である。
【００１９】
更に、詳しく説明すると、前記各上部半体３５ａ〜３５ｄはいずれも同じ形状からなり、下側壁１８ｂの係止凹部３２に嵌入して固着される合成樹脂製の上部取付板３８に外部から切断して切離し可能な合成樹脂製の取付片３９を介して一体に設けられる。前記上部取付板３８にはその上端縁に前記下側壁１８ｂが嵌入する横溝４０が設けられると共に図５に示されるように下端縁に長手方向に沿って突条４１が設けられている。また、両側には下側壁１８ｂの両ねじ孔３３，３３と連通する通孔４２，４２が開設されている。
【００２０】
前記各上部半体３５ａ〜３５ｄは図４乃至図９に示されるように上下端面が開放した略直方筒体からなり内部に仕切壁４３が張設されている。これにより上端面に凹窪部４４が形成される。また、前記仕切壁４３の下面に前端面が開口４５した収納空間４６が形成される。該収納空間４６内には前記仕切壁４３から垂直に突設される係止片４７が配設され、該係止片４７に前記係合部材３７ａ〜３７ｄが係合する係合孔４８が開設されている。なお、前記各上部半体３５ａ〜３５ｄ間には補強のための連接片４９が一体に設けられる。
【００２１】
また、前記各下部半体３６ａ〜３６ｄも同じ形状からなり、前記台板１６の支持片２２に嵌着して固定される合成樹脂製の下部取付板５０に外部から切断して切離し可能な合成樹脂製の取付片５１を介して一体に設けられる。前記下部取付板５０には図５に示されるようにその下端縁に前記支持片２２が嵌入する横溝５２が設けられると共に上端縁には長手方向に沿って前記突条４１が嵌入する凹条５３が設けられている。また、両側には前記支持片２２の両ねじ孔２３，２３と連通する通孔５４，５４が開設されている。
【００２２】
前記各下部半体３６ａ〜３６ｄは、図４乃至図９に示されるように前記各上部半体３５ａ〜３５ｄと略同じ大きさの直方筒体からなり、上端面がガイド壁５５により閉塞され下端面が開放されている。また、前記ガイド壁５５は各下部半体３６ａ〜３６ｄの前面より前方へ突出され、その両側に囲壁５６，５６が立設されると共に該囲壁５６，５６の奥端部上面を覆う受壁５７に前記係合部材３７ａ〜３７ｄを仮に係止しておくための仮係止孔５８が開設される。更に、前記ガイド壁５５の奥端部に前記係止片４７の下端部が介入し得る係合凹部５９が設けられる。そこで、前記各上部半体３５ａ〜３５ｄが各下部半体３６ａ〜３６ｄに嵌合したとき、図８に示されるように前記ガイド壁５５の上面が係合孔４８の下側面と同一面となるようにしてある。なお、この場合も前記各下部半体３６ａ〜３６ｄ間には補強のための連接片６０が一体に設けられている。
【００２３】
前記係合部材３７ａ〜３７ｄは、基端部から上下平行に突設される一対の保持片６１，６１により側面コ字状に形成され、両保持片６１，６１の先端部外側面に爪部６２，６２が突設されている。両保持片６１，６１はその材質から弾力性が備えられている。
【００２４】
本発明に係る基板収納ケース１３は上記構成よりなり、まず前記カバー体１８の係止凹部３２に上部取付板３８を嵌入させ、両通孔４２，４２を介してねじ孔３３，３３にビス６３，６３を螺合することにより、上部取付板３８を下側壁１８ｂに固着する。また、前記台板１６の支持片２２に下部取付板５０を嵌合させ、両通孔５４，５４を介してねじ孔２３，２３にビス６４，６４を螺締することにより、下部取付板５０を支持片２２に固着しておく。そして、前記回路基板１７を台板１６の金属板１６ａの表面に重ね、各止着孔２９，２９…を介しビス３０，３０…を各突起２０，２０…のねじ孔１９，１９…に螺締して回路基板１７を台板１６に固着する。
【００２５】
次に、前記回路基板１７を覆うようにして台板１６にカバー体１８を被せ、該カバー体１８の両掛止孔３１，３１に台板１６の両掛止片２１，２１を係合させると共に係合手段Ａの突条４１を凹条５３に嵌入させる。これにより図２に示されるように各上部半体３５ａ〜３５ｄが下部半体３６ａ〜３６ｄに嵌合される。この状態で、図８に示されるように１組の上・下部半体３５ａ，３６ａを除いて前記各下部半体３６ｂ〜３６ｄのガイド壁５５に沿って係合部材３７ｂ〜３７ｄを収納空間４６の途中まで押し込み、一方の保持片６１先端の爪部６２を仮係止孔５８に係合させる。この際、前記各係合部材３７ｂ〜３７ｄはガイド壁５５と囲壁５６，５６により囲われるので、各係合部材３７ｂ〜３７ｄが不注意によって更に奥へ押し込まれることがなく、しかも抜け落ちることもない。なお、前記状態ではいずれも各上部半体３５ｂ〜３５ｄと下部半体３６ｂ〜３６ｄは分離できる。
【００２６】
そこで、前記上部半体３５ａと下部半体３６ａについては、前記各係合部材３７ｂ〜３７ｄと同じように操作し、更に図９に示されるように係合部材３７ａをガイド壁５５に沿って収納空間４６の奥端部まで押し込み、両保持片６１，６１の爪部６２，６２を係合孔４８に係合させる。これにより、前記係合部材３７ａが抜脱不能に挿通され、しかも前記上部半体３５ａと下部半体３６ａとが解除不能となる。そして、回路基板１７がカバー体１８内に密封される。このように前記上部半体３５ａと下部半体３６ａが解除不能に嵌合され外せないことから、不正を行うには取付片３９，５１及び隣接する上部半体３５ｂと下部半体３６ｂとの間の連接片４９，６０を無理に切断することとなり、その痕跡が明らかに残ってしかもその隠蔽も極めて困難であるため不正行為が行いにくい。また、その不正は容易に発見でき責任の所在も明確化される。
【００２７】
ところで、前記基板収納ケース１３は基板収納ケースの製造メーカーで組み立てられ、回路基板１７を基板収納ケース１３に収め、更に１つの嵌合された上部半体３５ａと下部半体３６ａに係合部材３７ａを抜脱不能に挿通し、残りの上・下部半体３５ｂ〜３５ｄ，３６ｂ〜３６ｄについては係合部材３７ｂ〜３７ｄを仮に係止して基板収納ケース１３を密封する。そして、このようにして密封された基板収納ケース１３は遊技機製造メーカーに納入され、パチンコ遊技機の裏面に透孔２５を介してビス１５を螺締することにより装着され、可変表示装置など各種部品から引き出される配線６５先端の接続用コネクター６５ａが各入出力用コネクター２８，２８…に接続される。
【００２８】
例えば遊技機製造メーカーまたはパチンコ遊技機が納入されたパチンコホールで基板収納ケース１３を検査するには、ニッパー等の工具を用いて前記取付片３９，５１及び連接片４９，６０を切断して解除不能に嵌合された上部半体３５ａと下部半体３６ａを切り離し、カバー体１８を開放してＲＯＭ２６ａを検査する。検査後は再びカバー体１８を取り付け、次の下部半体３６ｂのガイド壁５５に沿って係合部材３７ｂを収納空間４６の奥端部まで押し込み、両爪部６２，６２を係合孔４８に係合させることにより係合部材３７ｂを抜脱不能な状態とする。これによって前記次の上部半体３５ｂと下部半体３６ｂが解除不能に嵌合されることとなり、同じ作用を繰り返すことによってＲＯＭ２６ａの検査が３回行なえるようになっている。
【００２９】
また、図１０に示されるように各上部半体３５ａ〜３５ｄの凹窪部４４内すなわち仕切壁４３の上面と各下部半体３６ａ〜３６ｄのガイド壁５５の下面とにそれぞれ金属板６６を貼着するようにしても良い。これは、解除不能ないずれかの上・下部半体３５ａ〜３５ｄ，３６ａ〜３６ｄに上下方向から熱線またはドリルで穴を開け、係合部材３７ａ〜３７ｄを破壊まではいかないが破損させて上部半体３５ａ〜３５ｄと下部半体３６ａ〜３６ｄを無理に解除してＲＯＭ２６ａを改造するといった不正を防止するためである。
【００３０】
本実施の形態においては、カバー体１８を密封するに基板収納ケース１３の下側面のみに解除不能となし得る係合手段Ａを複数設けたが、該基板収納ケース１３の上側面または一側面に複数設けるようにしても良い。また、前記係合手段Ａにおける上部取付板３８はカバー体１８と一体に成形するようにすれば、これら組立作業が簡素化され組立作業の能率が向上する。更に、カバー体１８を金属製にすればノイズ防止にも役立ち、回路基板１７の種々の電子部品を静電気から保護することもできる。
【００３１】
図１１乃至図１５は係合手段Ａの他の実施の形態に係るものであり、他の部位は本実施の形態と同一なので同一符号を付すことによって説明を省略する。この実施の形態では、係合手段Ａが図１１に示されるように４個の上部半体６７ａ〜６７ｄと該各上部半体６７ａ〜６７ｄが嵌合する４個の下部半体６８ａ〜６８ｄと各上部半体６７ａ〜６７ｄの上方から挿通される係合部材６９ａ〜６９ｄとで構成される。これらはいずれも合成樹脂製である。
【００３２】
前記各上部半体６７ａ〜６７ｄは、上下端面が開放される直方筒体からなり、図１３に示されるように前側壁７０が左右側壁７１，７１と後側壁７２より下方へ長く形成されている。そして、各上部半体６７ａ〜６７ｂ内には後側を開口７３した受止壁７４が張設され、その上面に凹窪部７５が形成される。また、後側壁７２の内面に前記受止壁７４と同じ高さに位置させて第１係合爪７６が前方へ突設されている。また、前記前側壁７０と後側壁７２との上端縁に対向位置させて切欠７７，７７が設けられる。
【００３３】
また、前記各下部半体６８ａ〜６８ｄも直方筒体からなり、後側壁７８と周側壁７９を有し、その上面と前面が開放されている。そして、前記後側壁７８の内面に前記第１係合爪７６と上下方向で同じ位置に第２係合爪８０が前方へ突設されている。
【００３４】
また、前記各係合部材６９ａ〜６９ｄは、各上部半体６７ａ〜６７ｄの凹窪部７５に嵌着される方形状の平板状頭部８１の下面にロック板８２を垂設して構成され、該ロック板８２の上下部に前記第１・第２係合爪７６，８０が係合し得る第１係合孔８３と第２係合孔８４が開設されている。前記平板状頭部８１の前後端縁には、該平板状頭部８１を前記凹窪部７５に嵌着したとき、嵌入する耳片８５，８５が一体に突設されている。該各耳片８５，８５は、力を加えることにより容易に折り曲げ切除できるように薄肉に形成されている。
【００３５】
そこで、回路基板１７を覆うようにして台板１６にカバー体１８を被せ、各上部半体６７ａ〜６７ｄを各下部半体６８ａ〜６８ｄに嵌合させる。この状態で、図１４に示されるように一組の上・下部半体６７ａ，６８ａを除いた前記各上部半体６７ｂ〜６７ｄの上方から各係合部材６９ｂ〜６９ｄを挿入する。この際、両耳片８５，８５が両切欠７７，７７に嵌り込んで平板状頭部８１が凹窪部７５内に嵌着され、しかもロック板８２の第１係合孔８３の下縁に第１係合爪７６が係合する。この状態では、第１係合爪７６の係合により各係合部材６９ｂ〜６９ｄが仮止めされることとなり抜け落ちるようなこともなく、しかも第２係合爪８０が第２係合孔８４に係合してないことから、各上部半体６７ｂ〜６７ｄと下部半体６８ｂ〜６８ｄは解除可能となっている。
【００３６】
一方、前記上部半体６７ａと下部半体６８ａに対しては、同じように係合部材６９ａを挿通すると共に、図１５に示されるように係合部材６９ａを奥端部まで押し込む。この際、両耳片８５，８５は折れて切除され、平板状頭部８１が凹窪部７５内の受止壁７４上面に重なり、同時に第２係合孔８４に第２係合爪８０が係合する。このように平板状頭部８１が凹窪部７５内に完全に嵌入され、しかも第２係合爪８０の係合により係合部材６９ａが抜脱不能に挿通される。これにより、前記上部半体６７ａと下部半体６８ａとが解除不能となる。また、基板収納ケース１３を検査するには両上・下部半体６７ａ，６８ａの取付片３９，５１及び隣接する上・下部半体６７ｂ，６８ｂとの間の連接片４９，６０を切断して上・下部半体６７ａ，６８ａを切り離す。以下同様な作業を繰り返すことによってＲＯＭ２６ａの検査が３回行なえる。
【００３７】
図１６乃至図２０も係合手段Ａの他の実施の形態に係るものであり、他の部位は本実施の形態と同一なので同一の符号を付すことによって説明は省略する。この実施の形態では、係合手段Ａが図１６に示されるように４個の上部半体８６ａ〜８６ｄと該各上部半体８６ａ〜８６ｄが嵌合する４個の下部半体８７ａ〜８７ｄと各上部半体８６ａ〜８６ｄの上方から挿通される係合部材８８ａ〜８８ｄとで構成される。
【００３８】
前記各上部半体８６ａ〜８６ｄは、円筒体からなり図１８に示されるように下端面が開放されると共に後側の下半部分が切除されている。また、各上部半体８６ａ〜８６ｄ内には受止壁８９が張設され、その上面に凹窪部９０が形成される。該受止壁８９には中央に係合部材８８ａ〜８８ｄが挿通される円孔９１が開設され、その外側で該円孔９１の中心を挟んだ対称位置に該円孔９１と連通する一対の上挿通切欠９２，９２が開設されている。更に、前記受止壁８９の下側で各上部半体８６ａ〜８６ｄの内周面に前記一対の上挿通切欠９２，９２と位置をずらして、同じく前記円孔９１の中心を挟んだ対称位置にストッパー片９３，９３が突設されている。
【００３９】
また、前記各下部半体８７ａ〜８７ｄは、前記上部半体８６ａ〜８６ｄと同径の円筒体からなり、上端面が開放されると共に下端面は底壁９４により閉塞されている。また、前側の半分が切除されている。更に、各下部半体８７ａ〜８７ｄの上端部に上部半体８６ａ〜８６ｄの内径と同じ外径を有しかつ前記円孔９１と同じ内径を有する両端開放の短筒部９５が周設されている。該短筒部９５には前記上挿通切欠９２，９２と同位置に同じく下挿通切欠９６，９６が設けられる。
【００４０】
また、前記各係合部材８８ａ〜８８ｄは、各上部半体８６ａ〜８６ｄの凹窪部９０に嵌着される円板状頭部９７の下面に短軸部９８を垂設して構成される。該短軸部９８の外周面には、その両側にその長手方向に沿って前記上・下挿通切欠９２，９２，９６，９６に挿通される停止片９９，９９が突設され、その下端部に外側へ折れ曲り前記短筒部９５の下端面に係合する鉤部１００，１００が設けられている。また、前記短軸部９８の外周面に該各鉤部１００，１００と位置を違えてそれぞれ弾力性を有しかつ上部が外側に広がり、各係合部材８８ａ〜８８ｄを各上部半体８６ａ〜８６ｄに挿通したとき受止壁８９の下面に係合する保持片１０１，１０１が設けられる。前記円板状頭部９７の上面にはドライバー等の先端が嵌入する差込溝１０２が設けられるが、該差込溝１０２は各係合部材８８ａ〜８８ｄが一方向へのみ回軸し得るように形成されている。

そこで、回路基板１７を覆うようにして台板１６にカバー体１８を被せ、各上部半体８６ａ〜８６ｄを各下部半体８７ａ〜８７ｄに嵌合させる。この状態で、図１８，図１９に示されるように一組の上・下部半体８６ａ，８７ａを除いた前記各上部半体８６ｂ〜８６ｄの上方から各係合部材８８ｂ〜８８ｄを挿入する。すなわち、両停止片９９，９９を上挿通切欠９２，９２に合致させると共に短軸部９８を円孔９１内に押し込み、円板状頭部９７を凹窪部９０内へ嵌入させる。この際、弾発性を有する両保持片１０１，１０１は円孔９１内を通過するとき挟められ、通過後に元のように広がり図１９（ａ）に示されるように受止壁８９の下面に係合する。同時に前記短軸部９８の下部が図１９（ｂ）に示されるように短筒部９５を介して下部半体８７ｂ〜８７ｄ内に臨み、両停止片９９，９９が両下挿通切欠９６，９６内に臨んでいる。更に、前記停止片９９，９９下端部の鉤部１００，１００が短筒部９５の下側に位置している。この状態では、両保持片１０１，１０１の係合により各係合部材８８ｂ〜８８ｄが仮止めされて抜け落ちるようなことがなく、しかも両鉤部１００，１００が短筒部９５の下端面に係合してないことから、各上部半体８６ｂ〜８６ｄと下部半体８７ｂ〜８７ｄは解除可能となっている。
【００４２】
一方、前記上部半体８６ａと下部半体８７ａに対しては、同様に係合部材８８ａを上・下部半体８６ａ，８７ａ内に奥端部まで挿入し、更に円板状頭部９７の差込溝１０２にドライバー等（図示せず。）の先端を嵌入して前記係合部材８８ａを一方向へ回転させる。この際、両保持片１０１，１０１が上部半体８６ａの内周面の両ストッパー片９３，９３をその弾発力に抗して乗り越え、同時に両停止片９９，９９が上・下挿通切欠９２，９２，９６，９６内で一側に寄せられて係合部材８８ａが停止させられる。これにより、係合部材８８ａが一方向へは回転できず、他方へも回転することができなくなり、しかも図２０（ａ）に示されるように両保持片１０１，１０１が受止壁８９下面に係合しかつ図２０（ｂ）に示されるように鉤部１００，１００が短筒部９５の下端面に係合することから、係合部材８８ａが抜脱不能に挿通され、前記上部半体８６ａと下部半体８７ａとが解除不能となる。
【００４３】
基板収納ケース１３を検査するには前記両実施の形態と同じ作業を行なう。
なお、以上実施の形態では係合手段として４個の上・下部半体を設けたが、これらの数に限らず数を増やしても良いこと勿論である。
【００４４】
【発明の効果】
以上述べたように本発明に係る遊技機における基板収納ケースは、台板にカバー体を取り付けた状態で解除不能となし得る複数の係合手段によって前記カバーが無用に開封できないようにしたので、前記係合手段を切離さない限りカバー体を取り外すことができず、これにより、ＲＯＭを交換して改造するといった不正行為を防止することができる。
【００４５】
また、係合手段は上部半体を下部半体に嵌合すると共に係合部材を挿通するのみで、前記上・下部半体を解除不能に嵌合し得るので、操作が簡単であり作業が能率良く行なえる。
【００４６】
また、係合手段を外部から切離可能にかつ複数設けたので、ＲＯＭの検査が繰り返し可能となり、遊技機製造メーカーやパチンコホールなど複数回の検査に充分対応でき再利用が可能となるという効果が有る。

BACKGROUND OF THE INVENTION
The present invention relates to a board storage case that is attached to a gaming machine such as a pachinko gaming machine or a slot machine and controls its gaming operation.
[0002]
[Prior art]
In general, this type of gaming machine is provided with a board storage case having a circuit board for controlling the gaming operation at a predetermined location. The board storage case includes a base plate attached to the gaming machine, a circuit board fixed to the front surface of the base board and equipped with a large number of electronic components such as a CPU and ROM of a microcomputer, and substantially the same size as the base plate. And a box-like cover body that is attached to the base plate so as to cover the circuit board. These are overlapped, and further assembled together by inserting a screw into the cover body and tightening.

[Problems to be solved by the invention]
However, recently, in the pachinko hall, illegal acts such as remodeling the ROM of the circuit board without permission to make the game gambling frequently occur, and in order to prevent this, it is possible to straddle between the base plate and the cover body. When a sealing paper that is easily damaged is attached, and the sealing paper is damaged, it is considered that an illegal ROM replacement has been performed. However, after the seal paper has been skillfully peeled off and the internal ROM has been replaced, an illegal act of re-attaching the seal paper as it was is performed. There is a problem of not knowing.
[0004]
In order to prevent such an illegal act, there is a substrate storage case disclosed in, for example, Japanese Patent Laid-Open No. 6-269539. The board storage case includes a box body and a cover body that covers the box body, and includes an engagement hanging piece and an engagement protrusion that cannot release the inner side wall and the cover body of the box body from the outside. They are locked by means. According to this, there is no method other than cutting the latching hanging piece to open the substrate storage case, and if the latching hanging piece is cut, it can be immediately understood that an illegal process has been performed. However, there is a drawback that the substrate storage case once the latching hanging piece is cut cannot be reused.
[0005]
On the other hand, the circuit board storage case is sealed and the circuit board storage case is used for comparison inquiry inspection of ROM contents, for example, the manufacturer of the game machine with the circuit board storage case attached, and when installing the game machine in the pachinko hall, etc. In the case of inspection or failure, it is necessary to open all of them, and therefore, there is a demand for a structure that can open and seal the substrate storage case a plurality of times.
[0006]
Therefore, the present invention has been made in view of the above-mentioned problems and demands, and it is impossible to change the ROM of the circuit board housed inside and to modify it without permission. An object of the present invention is to provide a board storage case in a gaming machine that can be reused.
[0007]
[Means for Solving the Problems]
To achieve this object, the present invention provides a base plate that is attached to a predetermined location of a gaming machine, a circuit board that is fixed to the front surface of the base plate and controls the gaming state of the gaming machine, and is substantially the same size as the base plate. And a box-like cover body that is attached to the base plate so as to cover the circuit board, and the engagement means that can be made unreleasable when the cover body is attached to the base plate. The cover body cannot be unnecessarily opened, and a plurality of the engaging means can be separated from the outside.
[0008]
As described above, since the cover body cannot be unnecessarily opened by the engaging means that cannot be released when the cover body is attached to the base plate, the cover is made impossible by releasing the engaging means in a normal state. The circuit board is sealed in the body. As a result, it is possible to prevent an illegal act of remodeling by replacing the ROM. If the engaging means is disconnected and the illegal action is performed, it is immediately known that the illegal action has been performed by disconnecting the engaging means.
[0009]
Also, in the comparison inquiry inspection of ROM contents in the board storage cases at various places such as manufacturers of gaming machines, the cover body is opened by separating one engaging means that cannot be released in advance during the inspection. Inspect. After the inspection, the cover body is attached again, and the next engaging means cannot be released. Thus, by providing a plurality of engaging means that cannot be released, the substrate storage case can be opened and sealed a plurality of times and can be reused.
[0010]
A plurality of the engaging means are provided on the outer peripheral side surface of the base plate with the cover body attached. Each engaging means includes an upper half and a lower half which are integrally provided on the base plate and the cover body via attachment pieces separable from the outside, and are fitted to each other, and the upper A non-removable engagement member that is inserted when the lower half bodies are fitted to each other and can be made unreleasable by the upper and lower half bodies.

A connection connector 65a at the tip of the wiring 65 drawn from the component is connected to each of the input / output connectors 28, 28.
[0028]
For example, in order to inspect the substrate storage case 13 in a pachinko hall to which a gaming machine manufacturer or a pachinko gaming machine has been delivered, the attachment pieces 39 and 51 and the connecting pieces 49 and 60 are cut and released using a tool such as a nipper. The upper half body 35a and the lower half body 36a that are impossible to be fitted are separated, the cover body 18 is opened, and the ROM 26a is inspected. After the inspection, the cover body 18 is attached again, the engaging member 37b is pushed to the back end of the storage space 46 along the guide wall 55 of the next lower half 36b, and both the claw portions 62, 62 are inserted into the engaging holes 48. By engaging, the engaging member 37b is brought into a state in which it cannot be removed. As a result, the next upper half 35b and lower half 36b are irreversibly fitted, and the ROM 26a can be inspected three times by repeating the same operation.
[0029]
Further, as shown in FIG. 10, a metal plate 66 is pasted in the recessed portion 44 of each of the upper half bodies 35a to 35d, that is, the upper surface of the partition wall 43 and the lower surface of the guide wall 55 of each of the lower half bodies 36a to 36d.
