【発明の属する技術分野】
この発明は、パチンコ式遊技機における打球発射装置の制御回路部に係り、更に詳しくは、パチンコ式遊技機において、打球発射装置を制御する制御回路部に関するものである。
【0002】
【従来の技術】
パチンコ機やアレンジボール機、更にはスロットマシン(回胴式図柄組合わせ機)等に代表されるこの種の遊技機では、電源からの入力電圧の影響を受け易い駆動源用の電気部品、主としてモータやソレノイドを有する電動機器について、例えば打球発射装置、回転式図柄可変表示装置、大型の可変入賞装置、そして賞球(コイン)用の賞品払出装置等が不可欠な構成機器として装備されている。これらの電動機器は、何れも設定電圧範囲、つまり設定された入力電圧が適正な許容範囲に保持されているもとで、正常な駆動および本来の作動を行ない得るようになっているが、遊技機の電源投入時、遊技開始および継続中、そして特別遊技状態時において、作動不能または作動不良停止を生じて遊技不能を招くことがあった。ちなみに電動機器の作動不能等に係る主たる原因は、遊技機自体の不調や電動機器自体の故障による場合の他に、外的要因として遊技ホール内の商用電源の電圧が低下している場合、数台単位の遊技機に接続使用される1台のトランスの容量不足による電圧降下が挙げられ、また知られている。
【0003】
【発明が解決しようとする課題】
ところで従来から既に使用され、また新たに製造されているパチンコ機等の遊技機については、多くのメーカの何れのタイプのものにあっても、通常遊技ホールの商用電源AC100Vに対してAC24Vの低電圧で稼働し得るように設計、設定されているが、駆動用の電動機器に係る電圧の感知(検知)表示手段や技術の提案はなく、またこれを実施(付加)した遊技機も未だに1台もなかった。このため現実として、遊技者および遊技ホールの管理者(従業員)にあっては、設置されている遊技機や選択した遊技機において、電動機器が作動不能・停止した場合、その原因が故障または電圧降下の何れであるのか全く判断し得ない状況下に置かれてしまう。このためホール側では、その原因究明並びに復旧処置までの長い間、遊技機を使用不能のまま放置している有様であり、メーカ側に対する不信感を抱く一方で、ゲームを継続することができなくなった遊技者との間で大きなトラブルを招く問題があった。なお過去の遊技機において、発射装置の操作時に駆動源に対する通電報知用のパイロットランプを点灯する技術が見られたが、電圧の適・不適変化(高低変化)を検知して表示することは到底できず、また期待もできなかった。
【0004】
【発明の目的】
本発明は、前述した課題を好適に解決するべく提案されたものであって、遊技機に使用される打球発射装置に係る駆動用制御回路の電圧の適・不適変化を適正に検知して適宜発光表示し得るようにし、電圧の適否を目視により一早く判断して電動機器の作動不能・停止等の原因の早期究明を図り、適正な復旧処置に対応し得るようにしたパチンコ式遊技機における打球発射装置の制御回路部を提供することを目的とする。
【0005】
【課題を解決するための手段】
前記課題を克服し、所期の目的を達成するため、本発明に係るパチンコ式遊技機における打球発射装置の制御回路部は、
所要の電源電圧に接続されると共に、駆動源用の発射ソレノイドを含む打球発射装置を備えて、操作ハンドル部の操作に基いて遊技球が遊技領域内に打込まれてゲームを展開し得るパチンコ式遊技機において、
前記操作ハンドル部の操作入力条件に基いて、発射駆動源用の前記発射ソレノイドおよび球送り駆動源用の球送りソレノイドの作動を制御する回路基盤に、
AC電源が通電接続される電源用コネクタと、
通電されたAC電源を直流電圧に変換し、駆動可能な許容電圧が共に同じである前記発射ソレノイドおよび球送りソレノイドに電力を供給する1つの電源回路部と、
前記電源回路部に接続されて、該電源回路部から入力される直流電圧が前記発射ソレノイドおよび球送りソレノイドを駆動可能な電圧として適・不適であるかの適・不適変化を検知し得る1つの電圧検知回路と、
前記電圧検知回路の一端に接続され、該電圧検知回路で検知される直流電圧の適・不適変化に対応した条件で適宜区分発光し得る通電常灯用の発光部および電圧降下灯用の発光部を有する発光表示具とを設け、
前記回路基盤をケース内に収容セットすると共に、該ケースから前記発光表示具を目視可能に臨ませて区分発光状態を視認点検し得るように構成し、
前記発光表示具の通電常灯用の発光部は、前記電源回路部からの入力電圧を受けている間は常時発光する一方、
前記発光表示具の電圧降下灯用の発光部は、前記電源回路部からの入力電圧が、前記発射ソレノイドおよび球送りソレノイドが駆動可能な前記許容電圧以下になると発光態様が変化するようにし
前記通電常灯用の発光部と電圧降下灯用の発光部は、1個の2色発光LEDランプまたは色別区分される2個の単色発光LEDランプからなり、2色の合成色により電圧降下を表示するようにしたことを特徴とする。
【0006】
【作用】
遊技に供されている遊技機並びに駆動源用の電動機器に対する電圧条件について、通電常灯用の発光部と電圧降下点灯用の発光部を有する表示ランプを接続することで、これら表示ランプの表示を目視するだけで、通電状態の有無と電圧不足・降下の有無とを明確に区分して、一早く的確に判断することができる。そして駆動源用の電動機器に対する入力電圧の適・不適変化に対して、1個の2色発光LEDランプまたは2個の単色発光LEDランプによる色別発光表示させ、通電状態および電圧降下状態を即座に色別判断することができる。何れの発光表示にあっても、通電状態を把握・確認したもとで電圧不足・降下状態を目視判断して、駆動源用の電動機器の駆動不能・停止に係る原因の早期究明を図ることができる。
【0007】
【発明の実施の形態】
次に、本発明に係るパチンコ式遊技機における打球発射装置の制御回路部について、好適な実施例を挙げて添付図面を参照しながら、以下詳細に説明する。なお本実施例では、遊遊機として便宜上パチンコ機やアレンジボール機等のパチンコ球使用機(以下パチンコ機ともいう)を対象例とし、これに電動機器の制御検知表示技術が実用された場合を主に説明する。
【0008】
本実施例のパチンコ遊技機は、その全体の基本的な構成として、図1および図2に略示するように、外枠1の開口前面側に開閉および着脱可能に組付けられた前枠2の各部に、各種の主要構成部材として、前面側にガラス扉4を組付けた窓枠3と、ソレノイド駆動タイプの球送り装置6を内側にセットした開閉式の上球皿5および定置式の下球皿7が夫々装備され、また正面右下部の前後に亘り電動式の打球発射装置8が装備されている。一方、前枠2の正面内部の保持枠9に、夫々のゲーム内容毎に応じた各種の遊技用部品等を配設して遊技終了球用の排出口11を開口した遊技盤10が交換可能にセットされており、また前枠2の裏側に電源AC24Vの接続部15、そして終了球および賞球の各処理部等を備えた機構セット盤14が着脱可能にセットされている。なお遊技機10の遊技部品の一つとして、ステッピングモータ(図示しない)を組込んだ回転式の図柄可変表示装置12と、電磁ソレノイド(図示しない)を組込んだ電動式の開閉入賞装置13を配設した例を示す。
【0009】
このようなパチンコ機にあって、駆動用の電動機器の代表例の一つに、前記打球発射装置8が挙げられる。この打球発射装置8では、前述の球送り装置6の球送りと協動して遊技球を打出すロータリーソレノイド駆動形態例のものにあって、基本的には図3,図4および図5に例示するように、前枠2の前側に装着セットされるグリップ体21に操作レバー22、タッチセンサ23、ソレノイド用スイッチ24および可変抵抗器による励磁力調整具25を組込んだ操作ハンドル部8Aと、前枠2の裏側に装着セットされるベース26に発射ソレノイド27および打球杆28を組付けた打球作動部8Bと、操作ハンドル部8Aの操作入力条件に基いて球送り作動と発射作動を制御する制御回路部8Cを備えている。そして、球送り装置6のソレノイド33と発射ソレノイド27とのパルス駆動制御に基いて、打球杆28が1回ずつ打球動作されることにおいて、具体例として約98個/分の発射性能に設定されている。また制御回路部8Cでは、打球作動部8Bのベース26裏側に着脱可能に組付けられたケース29内に1枚の回路基盤30が収容セットされており、この基盤30に構成された夫々の回路に、電源用、前記球送りソレノイド33用、励磁力調整具25用、そしてタッチセンサ23およびスイッチ24用の夫々のコネクタ41,42,43,44,45が、図示右側から順に接続され、また同基盤30に可変抵抗器によるタッチ感度調整具31および球飛び調整具32が配設されている。
【0010】
前述したパチンコ機にあって、本実施例の制御検知表示装置は、発生した電圧降下の影響を受けて遊技機能上最も大きな支障を来たすことが考えられる電動機器を対象として、前述の打球発射装置8の制御回路部8Cの回路基盤30に付設した例を示し、発射ソレノイド27や球送りソレノイド33に係る電圧の適・不適変化、つまり高低変化(励磁力の強弱変化)を検知して発光表示するようになっている。そしてこのような制御検知表示装置では、基本的な構成として図4および図6に例示するように、回路基盤30の電源回路部37に対して新たに形成付加された電圧検知回路35と、この回路35の一端に接続されて遊技機の所要位置に配置可能とされた発光表示具36とを備えて構成され、実質的には回路基盤30単位またはケース29単位で製作されて、球送り・発射駆動用の制御基盤としても取扱い得るようになっている。なお発光表示具36については、2色発光部で色別照明(具体的には緑色発光部Gと赤色発光部Rとによる点灯または点滅)し得る1個のLEDランプ(発光ダイオードランプ)を使用して回路基盤30の一端に配置した例を示し、ケース29の外表面から色別照明状態を目視し得るようになっている(図4および図5参照)。
【0011】
そこで本実施例の制御検知表示装置について、具体的に説明する。但し電源AC24Vに接続される前記打球発射装置8における回路基盤30内では、直流電圧に変換使用されるように設計されているので、以下の説明においては、便宜上理論的に換算した直流電圧単位値を主に記載して説明する。すなわち図6に例示する電圧検知回路35においては、電源回路部37からの入力電圧V(基準電圧としてDC33.9V)がコンパレータ(電圧比較回路)35aの第1入力端子(1番ピン)に入力され、また第2入力端子(2番ピン)に予じめ設定された比較電圧V2(基準電圧としてDC5V)が入力されるように設定されている。このもとで同回路35に対する前記発光表示具36の接続例として、常に入力電圧が供給される線(以下「供給線」ともいう)35bに通電常灯用の緑色発光部Gが接続され、一方コンパレータ35aの出力端子(3番ピン)に接続された線(以下「変圧線」ともいう)35cに電圧降下灯(異常灯)用の赤色発光部Rが接続された例を示す。なお同回路35中の符号について、R7〜R11は抵抗、C4,C5はコンデンサを夫々示す。
【0012】
前述のように構成された電圧検知回路35において、電源回路部37からの入力電圧Vは、抵抗R7とR8により分圧されてコンパレータ35aの第1入力端子に入力される。そして、この入力電圧V1(V1<V)がコンパレータ35aの第2入力端子に入力されている比較電圧V2以上であると、コンパレータ35aの出力端子が“Lレベル”に変化されるために、変圧線35cを介して赤色発光部Rに供給されている電圧V3が低下(約DC0.6V位)されて、同発光部Rが発光停止、つまり消光される。この結果、発光表示具36では、供給線35bからの電圧を受けている常灯用の緑色発光部Gのみが常時発光保持されることになり、この緑色点灯照明により通電状態における入力電圧Vが正常、つまり適正電圧条件にあることが表示されて目視し得る。言換えると、発射ソレノイド27および球送りソレノイド33が適正電圧条件で正常に駆動(打球作動および球送り作動)している場合には、緑色点灯表示されている。そして緑色点灯表示されている場合には、発射ソレノイド27および球送りソレノイド33が、共に適正電圧条件で正常に駆動(打球作動および球送り作動)される。
【0013】
一方前記コンパレータ35aの第1入力端子に入力された電圧V1が前記比較電圧V2以下になった場合には、コンパレータ35aの出力端子が“Hレベル”に変化されるために、変圧線35cを介して赤色発光部Rに供給されている電圧V3が必要値に高められて、同発光部Rが発光される。この結果、発光表示具36では、双方の発光部G,Rが夫々の供給線35b,変圧線35cからの電圧を受けて発光保持されることになり、緑色と赤色が合成された橙色の点灯照明により入力電圧Vが異常、つまり必要値以下の不適正な電圧降下条件であることが表示されて目視し得る。言換えると、発射ソレノイド27および球送りソレノイド33が不適正電圧条件で異常駆動(作動不能や作動不良)している場合には、橙色点灯表示されている。そして橙色点灯表示されている場合には、発射ソレノイド27および球送りソレノイド33が、共に不適正電圧条件のために異常駆動(作動不能や作動不良遅れ)される。
【0014】
なお本実施例の制御検知表示装置による色別発光条件については、前記球送り・発射装置6,8に使用される夫々のソレノイド33,27に係る駆動可能な許容電圧(定格電圧AC24Vから試験的に得られたAC20V位までの範囲)に合わせて設定される。これに基いて発光表示具36の具体的な発光例として通電常灯用の緑色発光部Gは、前記電源回路部37からの入力電圧Vを常に受けて発光(点灯ON)されることに対して、異常灯用の赤色発光部Rは、入力電圧Vを基準に観てDC28.4V(換算値AC20.1V)以下の条件で発光(点灯ON)され、同電圧値以上では発光されない(未点灯OFF)条件に保持されるように設定されている。
【0015】
【実施例の作用】
前述した本実施例のパチンコ機は、商用電源AC100Vを引込み使用する遊技ホール内の設置枠台(通常「島」)に縦向きに設置されて、通電(AC24Vの入電)状態で遊技に供される。このもとで、打球発射装置8の操作ハンドル部8Aでの基本的な遊技操作により、球送り装置6のソレノイド33と打球作動部8Bの発射ソレノイド27が、制御回路部8Cの制御に基いて設定タイミングで協動されることにおいて、上球皿5内の遊技球が、発射レール34の基部に送込まれた後、打球杆28で当打されて遊技盤10の遊技領域内に打込まれ、以降同様に1球ずつ継続的に打込まれて所定のゲームが展開される。そしてゲームで使用された終了球(アウト球およびセーフ球)は、裏側の機構セット盤14の各排出処理部から機外へ排出され、一方セーフ球処理部16で1球ずつ検出処理される各々のセーフ球に対しては、賞球払出部17から所定数単位の賞球が払出されて、最終的には上球皿5、下球皿7へ順次排出される。
【0016】
一方、遊技に供された故障のないパチンコ機において、適正な通電条件(例えばAC24V〜AC20V位までの範囲)が維持されていない場合には、ゲームに多くの支障を来たして継続不能になることがある。すなわち通電不良の外的原因として、
(a) 設置枠台上のパチンコ機に接続使用された電源の電圧が何らかの事由により低下(例えばAC80V〜AC85V位)、
(b) 複数台単位のパチンコ機に接続使用された1台毎のトランスの容量不足に起因する電圧降下、
等が発生した場合では、パチンコ機が確かに通電接続されているにも拘らず、球送り装置6および打球発射装置8のソレノイド33,27が駆動不能または駆動不良・停止となり、更には図柄可変表示装置のモータ、入賞装置のソレノイド、賞球払出部のソレノイド等が作動不良または誤動作する等の大きなトラブルを惹起する。なお、電圧降下等は、ホールの開店当初の電源投入時、ゲーム進行中、特別遊技成立時等の何れの時期に発生するのか、管理者(従業員)および遊技者には予知,予測し得ない状況にあり、また電動機器の駆動不能・停止はどのような原因によるのか即時に判断し得ないために、その原因究明に長く手間取ってしまう。
【0017】
そこで前述のようなパチンコ機の通電電圧の適否について、本実施例の制御検知表示装置では、打球発射装置8の回路基盤30における電圧検知に基いて好適な色別発光表示を行ない得る。すなわち前述した図6の電圧検知回路35において、電源回路部37からの入力電圧Vが適正範囲〔例えばDC33.9V〜DC28.4V(換算値AC24V〜AC20.1V)〕で入力されている状況下では、供給線35b側に入力電圧Vが常に供給されていることに対して、コンパレータ35aの出力端子(3番ピン)から変圧線35c側に極めて低い電圧V3が供給される。これにより発光表示具36においては、通電常灯用の緑色発光部Gのみが常時発光(点灯ON)され、赤色発光部Rが消光(未点灯OFF)とされて、通電条件において適正電圧範囲内であることが表示される。一方、前記(a),(b)項に起因して、入力電圧Vが降下〔例えばDC28.4V(換算値AC20.1V)以下〕した場合には、コンパレータ35aの出力端子から変圧線35cに必要値に高められた電圧V3が供給される。これにより発光表示具36においては、前記緑色発光部Gの発光に対して赤色発光部Rが新たに発光(点灯ON)されて、双方の合成色による橙色表示をもって通電状態であっても不適正電圧であることが表示される。
【0018】
従ってこのような本実施例の制御検知表示装置によれば、遊技に供されたパチンコ機における球送り・発射装置の駆動不能・停止の原因を一早く的確に判断できる。具体例として、前述の電圧変化(電圧降下)が管理者および遊技者の予測し得ないどのような時期に発生したとしても、球送り装置6および打球発射装置8による本来の球送り・打球作動が不能または停止された現状において、当該遊技者からの連絡(通報)を受けた管理者は、その原因究明の対応として、前枠2全体を解錠開放して裏側の制御回路部8Cを目視する。そして同回路部8Cのケース29に臨む発光表示具36において、前述した緑色表示または橙色表示を確認した時点で、通常状態を確認し得ると共に機全体および球送り・打球作動の不能・停止の原因を即時に判断し得るものである。なお原因とされた前記(a),(b)項に対する適正な復旧対策・処理がなされた以後においては、パチンコ機が正常な通電電圧条件に保持されることになり、前枠2全体を元の閉鎖状態にセットしたもとで、球送り・打球作動を含む本来のパチンコゲームを再開し、継続することができる。ちなみにパチンコ機の正常通電電圧条件では、緑色発光表示とされる。
【0019】
【変更例】
本発明の対象とするパチンコ式遊技機における打球発射装置の制御回路部は、前述した実施例だけに制限されず、これを応用した他の形態例も好適に推奨される。例えば図6に例示する電圧検知回路35において、発光表示具36は供給線35bおよび変圧線35cに対してコネクタ38で接続して、遊技機の前面側、例えば前枠2、上下の球皿5,7、打球発射装置8の操作ハンドル8A等の表面所要部位に臨ませてもよく(図1参照)、この際発光表示具36自体については、例えば緑色と赤色に区分される2個の単色LEDランプを配置してもよい。また図6とは別に構成された電圧検知回路にあって、発光表示具の発光条件例として、1個のLEDランプ,蛍光ランプまたは豆球ランプを使用して点灯と点滅の切換え表示式にしたり、あるいは不適正電圧(電圧降下)の検知に対して単色発光する1個のランプを接続してもよい。また電圧の高低変化を段階的に検知し得る回路に対して、同色または多色のランプを各レベル位置に配置して発光表示する形態としたり、液晶表示を利用してもよい
【0020】
【発明の効果】
以上に説明したように、本発明のパチンコ式遊技機における打球発射装置の制御回路部によれば、打球発射装置による作動に基いてゲームを展開・継続し得る遊技機に必要とされる所定の電源電圧が適・不適変化した場合、これを検知して区分発光表示し得るものであるから、この区分発光表示状態を目視するだけの簡単な点検により、当該遊技機の電圧状態の適否が一早く容易に判断できる。従って、遊技機に対する電源投入(通電)時、ゲーム進行中あるいは特別遊技条件成立時等の何れの時期に、打球発射装置が駆動不能・停止してゲームが継続不良となったとしても、前述の発光表示状態の目視を以って、通電状態を確認し得るもとで、その原因が電圧の不足や降下によるものと早期的確に判断できる。そして原因の早期究明により適切な復旧対策処理を手早く行なって遊技機並びに打球発射装置を適正な電圧条件に戻したもとで、本来のゲームを再開することができ、遊技者とのトラブルを軽減することもできる。しかも装置自体が、対象とする打球発射装置に係る制御基盤単位で簡単かつ安価に構成し得ると共に、容易に取扱い、保管することができる。
【0021】
また、本発明のパチンコ式遊技機における打球発射装置の制御回路部によれば、具体的には遊技に供されているパチンコ式遊技機打球発射装置に対する電圧条件について、入力電圧の適・不適変化に対して、1個の2色発光LEDランプまたは2個の単色発光LEDランプによる色別発光表示を目視するだけで、通電状態および電圧降下状態を即座に色別判断できるので、通電状態を把握・確認したもとで、電圧不足・降下状態を目視判断して、打球発射装置の駆動不能・停止に係る原因の早期究明を図ることができる。

There was no stand. For this reason, in reality, for players and game hall managers (employees), in the installed gaming machine or the selected gaming machine, if the electric equipment is inoperable / stopped, the cause is The situation is such that the voltage drop cannot be determined at all. Therefore, on the hall side, it seems that the gaming machine has been left unusable for a long time until the cause investigation and restoration treatment, and the game can be continued while feeling distrust to the manufacturer side. There was a problem that caused great troubles with lost players. In past gaming machines, a technology to turn on the pilot lamp for notifying the energization of the drive source when operating the launching device was seen, but it is impossible to detect and display appropriate / inappropriate voltage change (high / low change). I couldn't and I couldn't expect it.

[0009]
In such a pachinko machine, the hitting ball launching device 8 can be cited as one of representative examples of the driving electric device. This hitting ball launching device 8 is of a rotary solenoid driving mode in which a game ball is hit in cooperation with the aforementioned ball feeding of the ball feeding device 6 and is basically shown in FIG. 3, FIG. 4 and FIG. As illustrated, an operation handle portion 8A in which an operating lever 22, a touch sensor 23, a solenoid switch 24, and an exciting force adjustment tool 25 using a variable resistor are incorporated in a grip body 21 mounted and set on the front side of the front frame 2; The base ball 26 mounted and set on the back side of the front frame 2 has a ball striking operation unit 8B in which a firing solenoid 27 and a ball striking rod 28 are assembled, and a ball feed operation and a firing operation based on the operation input conditions of the operation handle unit 8A.

Then, based on the pulse drive control of the solenoid 33 and the firing solenoid 27 of the ball feeding device 6, the firing performance is set to about 98 / min as a specific example when the hitting ball 28 is hit once. Has been. Further, in the control circuit unit 8C, a single circuit board 30 is accommodated and set in a case 29 that is detachably attached to the back side of the base 26 of the hitting ball actuating part 8B, and each circuit configured in the base 30 is provided.

[0010]
In the pachinko machine described above, the control detection display device of the present embodiment is intended for an electric device that is considered to cause the greatest trouble in the gaming function due to the influence of the generated voltage drop. 8 shows an example attached to the circuit board 30 of the control circuit unit 8C, and displays a light emission by detecting an appropriate / inappropriate change in voltage related to the firing solenoid 27 and the ball feed solenoid 33, that is, a change in height (change in strength of excitation force). It is supposed to be. In such a control detection display device, as illustrated in FIGS. 4 and 6 as a basic configuration, a voltage detection circuit 35 newly formed and added to the power supply circuit portion 37 of the circuit board 30, and this The light emitting display 36 is connected to one end of the circuit 35 and can be arranged at a required position of the gaming machine. It can also be handled as a control base for launch drive. For the light-emitting indicator 36, one LED lamp (light-emitting diode lamp) that can be illuminated according to color by the two-color light-emitting portion (specifically, lighting or blinking by the green light-emitting portion G and the red light-emitting portion R) is used. Then, an example of arrangement at one end of the circuit board 30 is shown, and the illumination state by color can be visually observed from the outer surface of the case 29 (see FIGS. 4 and 5).
[0011]
Therefore, the control detection display device of this embodiment will be specifically described. However, the circuit board 30 in the ball striking device 8 connected to the power source AC24V is designed to be converted into a DC voltage. Therefore, in the following description, the DC voltage unit value theoretically converted for convenience. Is mainly described and explained. That is, in the voltage detection circuit 35 illustrated in FIG. 6, the input voltage V (DC 33.9 V as a reference voltage) from the power supply circuit unit 37 is input to the first input terminal (first pin) of the comparator (voltage comparison circuit) 35a. In addition, the comparison voltage V 2 (DC5V as a reference voltage) set in advance is input to the second input terminal (second pin). As an example of the connection of the light emitting display device 36 to the circuit 35, a green light emitting part G for an energized normal light is connected to a line 35b to which an input voltage is always supplied (hereinafter also referred to as “supply line”), On the other hand, an example is shown in which a red light emitting portion R for a voltage drop lamp (abnormal lamp) is connected to a line (hereinafter also referred to as “transformer line”) 35c connected to the output terminal (No. 3 pin) of the comparator 35a. In the circuit 35, R7 to R11 denote resistors, and C4 and C5 denote capacitors.
[0012]
In the voltage detection circuit 35 configured as described above, the input voltage V from the power supply circuit unit 37 is divided by the resistors R7 and R8 and input to the first input terminal of the comparator 35a. When the input voltage V 1 (V 1 <V) is equal to or higher than the comparison voltage V 2 input to the second input terminal of the comparator 35a, the output terminal of the comparator 35a is changed to “L level”. In addition, the voltage V 3 supplied to the red light emitting portion R via the transformation line 35c is reduced (about DC 0.6V or so), and the light emitting portion R stops emitting light, that is, extinguished. As a result, in the light emitting display device 36, only the green light emitting portion G for ordinary light receiving the voltage from the supply line 35b is always kept emitting light, and the input voltage V in the energized state is maintained by this green lighting. It is displayed that it is normal, that is, in an appropriate voltage condition, and can be visually observed. In other words, when the firing solenoid 27 and the ball feed solenoid 33 are normally driven under the proper voltage conditions (ball hitting operation and ball feeding operation), they are displayed in green. When the green light is displayed, both the firing solenoid 27 and the ball feed solenoid 33 are normally driven (hit and ball feed operation) under appropriate voltage conditions.
[0013]
On the other hand, when the voltage V 1 input to the first input terminal of the comparator 35a becomes equal to or lower than the comparison voltage V 2 , the output terminal of the comparator 35a is changed to “H level”. The voltage V 3 supplied to the red light emitting unit R via the voltage is increased to a necessary value, and the light emitting unit R emits light. As a result, in the light emitting display 36, both light emitting portions G and R receive light from the supply line 35b and the transformation line 35c and are held to emit light, and the orange lighting in which green and red are synthesized is performed. Illumination indicates that the input voltage V is abnormal, that is, an inappropriate voltage drop condition that is less than or equal to the required value, and can be viewed. In other words, when the firing solenoid 27 and the ball feed solenoid 33 are abnormally driven (inoperable or defective) under an inappropriate voltage condition, they are lit in orange. When the orange lighting is displayed, both the firing solenoid 27 and the ball feed solenoid 33 are abnormally driven (inoperable or defective in operation) due to inappropriate voltage conditions.
[0014]
In addition, about the light emission conditions classified by color by the control detection display apparatus of a present Example, the driveable permissible voltage concerning each solenoid 33,27 used for the said ball | bowl feeding / launching apparatus 6,8 (from the rated voltage AC24V experimentally). In the range up to about AC20V obtained in (1). Based on this, as a specific example of light emission of the light-emitting indicator 36, the green light-emitting portion G for the energized normal lamp always receives the input voltage V from the power supply circuit portion 37 and emits light (lights ON). Thus, the red light emitting portion R for the abnormal lamp emits light (lights ON) under the condition of DC 28.4V (converted value AC20.1V) or less with reference to the input voltage V, and does not emit light above the same voltage value (not yet). (Lighting OFF) is set to be held in the condition.
[0015]
[Effect of the embodiment]
The pachinko machine of the present embodiment described above is installed vertically on an installation frame base (usually “island”) in a game hall that draws in and uses the commercial power supply AC100V, and is supplied to the game in an energized state (AC24V input). The Under this condition, the solenoid 33 of the ball feeder 6 and the firing solenoid 27 of the ball actuating unit 8B are operated under the control of the control circuit unit 8C by the basic game operation at the operation handle unit 8A of the ball hitting device 8. In cooperation with the set timing, the game balls in the upper ball tray 5 are sent to the base of the launch rail 34 and then hit with the hitting ball 28 to hit into the game area of the game board 10. After that, the same game is continuously struck one by one and a predetermined game is developed. The end balls (out ball and safe ball) used in the game are discharged from the discharge processing units of the mechanism set board 14 on the back side to the outside of the machine, while the safe ball processing unit 16 detects and processes one ball at a time. For the safe balls, a predetermined number of prize balls are paid out from the prize ball paying unit 17 and finally discharged sequentially into the upper ball tray 5 and the lower ball tray 7.
[0016]
On the other hand, in a pachinko machine that is used for gaming without any failure, if the proper energization conditions (for example, the range from AC24V to AC20V) are not maintained, it will cause many troubles in the game and will not be able to continue. There is. In other words, as an external cause of power failure,
(a) The voltage of the power source connected to the pachinko machine on the installation frame is lowered for some reason (for example, about AC80V to AC85V),
(b) Voltage drop due to insufficient capacity of each transformer connected to and used in multiple pachinko machines.
Etc., the solenoids 33 and 27 of the ball feeding device 6 and the hitting ball launching device 8 cannot be driven or are not driven or stopped even though the pachinko machine is surely energized and connected. The motor of the display device, the solenoid of the winning device, the solenoid of the winning ball paying unit, etc. cause a serious trouble such as malfunction or malfunction. It should be noted that the voltage drop, etc. may occur at the beginning of the hall opening, when the game is in progress, when a special game is established, etc., for managers (employees) and players. In other situations, it is impossible to immediately determine what causes the inability to stop or stop the electric device, so it takes a long time to investigate the cause.
[0017]
Therefore, regarding the suitability of the energization voltage of the pachinko machine as described above, the control detection display device of the present embodiment can perform appropriate color-based light emission display based on voltage detection in the circuit board 30 of the ball hitting device 8. That is, in the voltage detection circuit 35 of FIG. 6 described above, the input voltage V from the power supply circuit unit 37 is input in an appropriate range [for example, DC 33.9 V to DC 28.4 V (converted value AC 24 V to AC 20.1 V)]. in respect to the input voltage V to the supply line 35b side is always supplied, a very low voltage V 3 is supplied to a transformer line 35c side from the output terminal of the comparator 35a (3 pin). As a result, in the light-emitting indicator 36, only the green light emitting portion G for the current-carrying normal lamp is always lighted (lighted ON), and the red light-emitting portion R is extinguished (not lighted OFF). Is displayed. On the other hand, when the input voltage V drops [for example, DC28.4V (converted value AC20.1V) or less) due to the items (a) and (b), the output terminal of the comparator 35a is connected to the transformation line 35c. A voltage V 3 increased to the required value is supplied. As a result, in the light emitting display device 36, the red light emitting portion R is newly emitted (lighted ON) with respect to the light emitted from the green light emitting portion G, and it is inappropriate even if it is energized with an orange display of both composite colors. The voltage is displayed.
[0018]
Therefore, according to the control detection display device of this embodiment, it is possible to quickly and accurately determine the cause of the impossibility of driving or stopping the ball feeding / launching device in the pachinko machine provided for the game. As a specific example, even if the above-described voltage change (voltage drop) occurs at any time that cannot be predicted by the administrator and the player, the original ball feeding / hitting operation by the ball feeding device 6 and the ball hitting device 8 In the current situation where the player has been disabled or stopped, the manager who has received the communication (report) from the player, as a response to the cause investigation, unlocks the entire front frame 2 and visually checks the control circuit portion 8C on the back side. To do. In the light emitting display device 36 facing the case 29 of the circuit portion 8C, when the above-described green display or orange display is confirmed, the normal state can be confirmed, and the entire machine and the cause of disabling / stopping the ball feeding / hitting operation can be confirmed. Can be determined immediately. After appropriate recovery measures and processing for the above-mentioned items (a) and (b) are made, the pachinko machine will be maintained at normal energized voltage conditions, and the entire front frame 2 will be restored. In the closed state, the original pachinko game including ball feeding and hitting operation can be resumed and continued. By the way, green light emission is displayed under the normal energizing voltage condition of the pachinko machine.
[0019]

For example, in the voltage detection circuit 35 illustrated in FIG. 6, the light emitting display 36 is connected to the supply line 35 b and the transformation line 35 c with a connector 38, and the front side of the gaming machine, for example, the front frame 2, the upper and lower ball trays 5. 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, etc., and the light emitting display 36 itself may be divided into, for example, two single colors divided into green and red An LED lamp may be arranged. In addition, in the voltage detection circuit configured separately from FIG. 6, as an example of the light emission condition of the light emitting indicator, a single LED lamp, a fluorescent lamp, or a bean bulb lamp can be used to switch between lighting and blinking. Alternatively, a single lamp that emits monochromatic light may be connected to detect an inappropriate voltage (voltage drop). Further, for a circuit capable of detecting a change in voltage level in stages, the same color or multicolor lamps may be arranged at each level position to emit light, or a liquid crystal display may be used .
