【０００１】
【発明の属する技術分野】
本発明は、各金種硬貨に応じた内径を有する硬貨収納筒から硬貨を繰り出すことが可能な硬貨出金機あるいは硬貨入出金機等の硬貨処理機に用いられ、さらに詳しくは、硬貨収納筒内の状況を判断することが可能な収納硬貨判別装置に関する。
【０００２】
【従来の技術】
従来、金種硬貨に応じた内径を有する硬貨収納筒を鉛直状に設置して、その内径に硬貨を収納し、この収納された硬貨を、該硬貨収納筒の最下部近傍に設けられ水平に移動する繰り出し片によって、最下部の硬貨から１枚ずつ繰り出すとともに、この繰り出された硬貨の通過を発光／受光素子よりなる繰り出し確認センサの検出結果から確認し、下方に設置される受け皿に放出するよう構成された硬貨出金機が知られている。
このような金種別の硬貨収納筒を有する硬貨出金機あるいは硬貨入出金機等の硬貨処理機においては、この硬貨収納筒の内径よりも小径の金種硬貨が、その金種に応じた硬貨とともに混入してしまうことがあるが、このように混入した異金種硬貨を選別する装置としては、既に特開平７−２９６２１２号公報が開示されている。
【０００３】
この硬貨出金機は、前記硬貨収納筒の最下部と前記繰り出し片によって繰り出された硬貨を確認する繰り出し確認センサ（検知センサ）との間に、硬貨収納筒の最下部から繰り出された硬貨の搬送をガイドする選別通路（ガイド部材）を設けるとともに、この選別通路の途中に該硬貨収納筒に応じた金種硬貨のみを通過可能とし、且つこれよりも小径の硬貨のみを落とし込む選別孔を設け、硬貨収納筒から繰り出し片によって繰り出された硬貨が異金種硬貨となる小径硬貨である場合には、該異金種硬貨をこの選別孔から落下させて選別孔の下部に設けられる収納ボックスに収納する、一方、その硬貨収納筒に応じた金種硬貨は、繰り出し片によって選別通路の終端まで押し出されて、下方に設置される受け皿に放出されるように構成されている。
【０００４】
【発明が解決しようとする課題】
しかしながら、異金種硬貨を選別可能とするこの構成では、少なくとも硬貨収納筒の最下部と硬貨収納筒から押し出された硬貨の通過を検出する繰り出し確認センサとの間に異金種硬貨の選別を可能とする長さの選別通路を設けなければならず、結果的にこの選別通路の部分が機体の奥行き方向において大きな空間を占有してしまい、機体全体が大型化する結果となってしまうことになる。
本発明は、以上の点に鑑みてなされたものであり、硬貨収納筒に混入する異金種硬貨を機体を大型化させることなく検出することが可能となる硬貨処理機における収納硬貨判別装置を提供することを目的とするものである。
【０００５】
【課題を解決するための手段】
上記目的を達成するため、本発明の請求項１記載の硬貨処理機における収納硬貨判別装置は、硬貨収納筒から繰り出される硬貨を検出可能な位置に設けられ、検出対象物の磁気的性質を検出する磁気検出手段と、磁気検出手段が各金種硬貨を検出した時の検出デ−タを金種別の基準硬貨デ−タとして記憶する検出デ−タ記憶手段と、磁気検出手段が繰り出される硬貨を検出した時の検出デ−タと前記検出デ−タ記憶手段が記憶する硬貨収納筒に応じた金種の基準硬貨デ−タとを比較して、該検出デ−タが硬貨収納筒に応じた金種の基準硬貨デ−タに一致しなければ、該硬貨を異金種硬貨と判断する制御手段とを有するものであり、これによって、異金種硬貨を検出するための構成を最低限に抑えながら、確実に硬貨収納筒内に混入する異金種硬貨を検出することが可能となる。
しかも、本発明の請求項１記載の硬貨処理機における収納硬貨判別装置は、磁気検出手段を繰り出される硬貨が硬貨収納筒内に位置する時にこれを検出可能な位置に設けるとともに、検出デ−タを硬貨の繰り出し動作が行なわれていない時に求めて異金種硬貨か否かを判断しており、これによって異金種硬貨であると判断した場合にこの繰り出しを停止させることが可能となる。
本発明の請求項２記載の硬貨処理機における収納硬貨判別装置は、検出対象物が無い時の磁気検出手段からの検出結果を検出対象物無しデ−タとして検出デ−タ記憶手段に記憶し、求められた検出デ−タと検出対象物無しデ−タとを比較することによって検出対象物の有無を判断することができ、これによって、硬貨収納筒内の有無を判断することが可能となる。
本発明の請求項３記載の硬貨処理機における収納硬貨判別装置は、硬貨収納筒から繰り出される硬貨を検出可能な位置に設けられ、検出対象物の磁気的性質を検出する磁気検出手段と、磁気検出手段が各金種硬貨を検出した時の検出デ−タを金種別の基準硬貨デ−タとして記憶する検出デ−タ記憶手段と、磁気検出手段が繰り出される硬貨を検出した時の検出デ−タと前記検出デ−タ記憶手段が記憶する硬貨収納筒に応じた金種の基準硬貨デ−タとを比較して、該検出デ−タが硬貨収納筒に応じた金種の基準硬貨デ−タに一致しなければ、該硬貨を異金種硬貨と判断する制御手段とを有するものであり、これによって、異金種硬貨を検出するための構成を最低限に抑えながら、確実に硬貨収納筒内に混入する異金種硬貨を検出することが可能となる。
しかも、本発明の請求項３記載の硬貨処理機における収納硬貨判別装置は、磁気検出手段を硬貨収納筒から繰り出される硬貨の通過を検出可能な位置に設け、該繰り出された硬貨の検出デ−タと各金種の基準硬貨デ−タとを比較することによって、異金種硬貨か否かを判断することができるとともに繰り出された硬貨の有無を確認でき、これにより、繰り出し動作において硬貨収納筒から硬貨が繰り出されたか否かを確実に確認することが可能となる。
本発明の請求項４記載の硬貨処理機における収納硬貨判別装置は、磁気検出手段を、繰り出される硬貨が硬貨収納筒内にあるときに、少なくとも該硬貨の有無を検出可能な位置に設けるとともに、検出対象物が無い時の磁気検出手段からの検出結果を検出対象物無しデ−タとして検出デ−タ記憶手段に記憶し、さらに硬貨の繰り出し動作が行なわれていない時の任意の磁気検出手段からの検出結果を硬貨有無検出デ−タとして求め、この硬貨有無検出デ−タと前記検出対象物無しデ−タを比較することによって硬貨の有無を確認でき、これによって、硬貨収納筒内の硬貨の有無を確認することが可能となる。
本発明の請求項５記載の硬貨処理機における収納硬貨判別装置は、硬貨収納筒から繰り出される硬貨を検出可能な位置に設けられ、検出対象物の磁気的性質を検出する磁気検出手段と、磁気検出手段が各金種硬貨を検出した時の検出デ−タを金種別の基準硬貨デ−タとして記憶する検出デ−タ記憶手段と、磁気検出手段が繰り出される硬貨を検出した時の検出デ−タと前記検出デ−タ記憶手段が記憶する硬貨収納筒に応じた金種の基準硬貨デ−タとを比較して、該検出デ−タが硬貨収納筒に応じた金種の基準硬貨デ−タに一致しなければ、該硬貨を異金種硬貨と判断する制御手段とを有するものであり、これによって、異 金種硬貨を検出するための構成を最低限に抑えながら、確実に硬貨収納筒内に混入する異金種硬貨を検出することが可能となる。
しかも、本発明の請求項５記載の硬貨処理機における収納硬貨判別装置は、磁性体から成る繰り出し片を用いるとともに、この繰り出し片が検出可能となる位置に磁気判別手段を設け、さらに、検出デ−タ記憶手段に磁気判別手段が繰り出し片を検出した時の基準繰り出し片デ−タを記憶し、繰り出し動作中に検出した繰り出し片デ−タと基準繰り出し片デ−タとを比較することによって繰り出し片の有無を確認でき、これにより、硬貨の繰り出し動作が行なわれたか否かを確認することが可能となる。
本発明の請求項６記載の硬貨処理機における収納硬貨判別装置は、磁性体から成る繰り出し片を用いるとともに、この繰り出し片が検出可能となる位置に磁気判別手段を設け、さらに、検出デ−タ記憶手段に磁気判別手段が繰り出し片を検出した時の基準繰り出し片デ−タを記憶し、繰り出し動作中に検出した繰り出し片デ−タと基準繰り出し片デ−タとを比較することによって繰り出し片の有無を確認でき、これにより、硬貨の繰り出し動作が行なわれたか否かを確認することが可能となる。
本発明の請求項７記載の硬貨処理機における収納硬貨判別装置は、求めた検出デ−タと、検出デ−タ記憶手段に記載される金種別の基準硬貨デ−タ、検出対象物無しデ−タ、基準繰り出し片デ−タとを比較し、該検出デ−タがいずれにも一致しなければ、各金種硬貨、検出対象物無し、繰り出し片でもない、異物と判断することができる。
【０００６】
【発明の実施の形態】
本発明の硬貨処理機における収納硬貨判別装置の第１の実施の形態について図１乃至図３を参照して説明する。
図１は、本発明の一例である硬貨処理機の特定の１金種における硬貨繰り出し装置Ａに関する概略構成を示すものであり、硬貨処理機では取り扱う金種の数に応じてこの硬貨繰り出し装置Ａを有する。
したがって、以下では、この１金種における硬貨繰り出し装置Ａの構成を中心に説明する。
この硬貨繰り出し装置Ａは、金種硬貨に応じた内径を有し、収納する硬貨１を鉛直方向に集積する硬貨収納筒２と、該硬貨収納筒２内に収納される硬貨１を１枚ずつ繰り出すための図示しない繰り出し機構とから構成されるものである。
前記硬貨収納筒２は、その下部に後述する繰り出し片３が硬貨収納筒２内に挿入可能となる繰り出し片用孔４と、これと同じ高さ位置である反対側に形成され繰り出される硬貨１枚が通過可能となる繰り出し用孔５と、硬貨収納筒２の底部に形成され、後述する検出コイル７が挿入可能な大きさを有する検出コイル用孔８とが形成されている。
この硬貨収納筒２の近傍には、前記繰り出し用孔４と同じ高さ位置に設けられ該硬貨収納筒２の繰り出し片用孔４に挿入されて硬貨収納筒２内に収納される最下部の硬貨１を前記繰り出し用孔５から１枚ずつ硬貨収納筒２外に繰り出すための繰り出し片３が設けられており、この繰り出し片３は、前記図示しない繰り出し機構の一部を構成するものである。
なお、図１の実線で示す位置が、繰り出し片３の繰り出し動作開始／終了位置となる。
また、前記硬貨収納筒２の繰り出し用孔５側には、前記繰り出し片３によって硬貨収納筒２外に繰り出された硬貨１の通過を検出可能な発光／受光素子より成る繰り出し確認センサ６が設けられている。
さらに、機体Ｂに硬貨収納筒２がセットされたときの検出コイル用孔８位置には該硬貨収納筒２内底部と同一面と成るよう形成されるとともに、硬貨収納筒２内底部における状況を検出するための検出コイル７が検出コイル用孔８を介して設けられている。
【０００７】
図２は、本発明の第１の実施の形態に係る硬貨処理機において、特に１金種における収納硬貨判別装置の構成を示すブロック図である。
前記検出コイル７は、硬貨収納筒２内底面に対し並列して設けられる発振コイル９及び受振コイル１０とから構成されており、この発振コイル９は、発振器１１から交流電流が供給されることによって磁場を発生させるとともに、これを受振コイル１０が受けると受振機１２から誘導電圧ｅが発生するようになっており、この誘導電圧ｅは、増幅器１３によって増幅され、直流変換器１４において整流平滑されて電圧Ｖｎが出力され、さらにＡ／Ｄコンバータ１５によってデジタル信号（検出データＤｎ）に変換されてＣＰＵ１６に供給されるようになっている。
ＣＰＵ１６は、このような検出データＤｎあるいは前記繰り出し確認センサ６からの信号を受け、必要な情報をＲＡＭ１７に記録するとともに、ＲＯＭ１８に記憶される制御プログラムに基づいて硬貨の繰り出し等の処理を行なう。
なお、上述したように、図示は省略するが硬貨処理機においては、取り扱う金種に応じて前記検出コイル７、発振器１１，受振機１２、増幅器１３、直流変換器１４、Ａ／Ｄコンバータ１５、繰り出し確認センサ６が設けられているものであり、ＣＰＵ１６は予めその硬貨収納筒２に対応した金種に応じてこれら信号を受けるものである。
また、図示しない操作部あるいは上位機からの出金指令及び出金金額等の信号はＩ／Ｏインターフェース１９を介してＣＰＵ１６へ供給されるようになっている。
さらに、前記ＲＯＭ１８には、前記検出コイル７上に各金種硬貨がある時の電圧ＶｎをＡ／Ｄコンバータ１５でＡ／Ｄ変換した任意の検出データＤｎに許容範囲±△を設けた基準硬貨データＤａと、検出コイル７上に検出対象物がない、つまり硬貨収納筒２内に硬貨１がない場合の電圧ＶｎをＡ／Ｄ変換した任意の検出データＤｎに許容範囲±△を設けた検出対象物無しデータＤｂと、検出コイル７上に前記繰り出し片３がある時の電圧ＶｎをＡ／Ｄ変換した任意の検出データＤｎに許容範囲±△を設けた基準繰り出し片データＤｃとが予め記憶されており、ＣＰＵ１６は、必要に応じて抽出した検出データＤｎと基準硬貨データＤａ、検出対象物無しデータＤｂ、基準繰り出し片データＤｃとを比較して適正な判断を下すようになっている。
なお、前記検出データＤｎは、検出コイル７上を検出対象物が完全に覆った時を前提とするものである。
【０００８】
次に、上記構成における本実施の形態の作用について説明する。
まず、図示しない上位機あるいは操作部から、出金指令及び金額データを受けると、この金額データに基づき金種別の繰り出し枚数が算出され、その金種において繰り出し枚数がある場合には、その金種に応じた硬貨繰り出し装置Ａの図示しない繰り出し機構が駆動されて、繰り出し片３による硬貨収納筒２内最下部の硬貨１枚の繰り出し動作が行なわれるとともに、繰り出し確認センサ６がこの繰り出された硬貨１を確認すると、その金種における繰り出し枚数を１枚減算し、その金種における繰り出し枚数が無くなるまで、この硬貨１枚の繰り出し動作が繰り返し行なわれるものである。
そして、ＣＰＵ１６は、供給される検出データＤｎから各金種における硬貨１枚の繰り出し動作を開始する前の任意のデータ（検出データＤ１）を抽出し、この検出データＤ１と前記ＲＯＭ１８に記憶される金種別基準硬貨データＤａ及び検出対象物無しデータＤｂとを比較することによって、硬貨収納筒２内の状態を判断し、その判断した結果に基づき必要な制御を行なうものである。
以下、特定の金種における硬貨の繰り出し動作と、ＣＰＵ１６に供給される検出データＤｎの推移を図３、図４に基づき具体的に説明する。
図３は、硬貨の繰り出し動作において、繰り出される硬貨及び次に繰り出される予定の硬貨のいずれも硬貨収納筒２に応じた適正な硬貨である場合を前提とした時の、検出データＤｎがＡ／Ｄ変換される前の電圧Ｖｎの推移をグラフに表したものであり、その縦軸が電圧Ｖ、横軸が時間Ｔとなる。
まず、上述するように繰り出す硬貨がその金種に応じた適正な硬貨であることを前提として繰り出し動作が開始Ｔ１されると、繰り出し片３は図１に示す硬貨収納筒２外の位置から、硬貨収納筒２内に進入し硬貨収納筒２内の最下部の硬貨１を押し出す。
【０００９】
この繰り出し片３が硬貨収納筒２内に進入して硬貨１を押し出すことにより、この押し出された硬貨１に代わって繰り出し片３が該検出コイル７上に移動してくると、直流変換器１４から出力される電圧Ｖｎに変化が生じる。
このように電圧Ｖｎが変化するのは、検出コイル７上を覆う検出対象物が次第に変わることによって起こるものであり、その異なる検出対象物における電圧Ｖｎの違いをグラフに表したのが図４となる。
この図４のグラフに示すように、硬貨の繰り出し動作において検出コイル７上を覆う、つまり検出対象物となりえるのは、検出コイル７上に各金種硬貨がある場合繰り出し片３がある場合、さらには検出コイル７上に検出対象物が無い場合などがあり、このような場合における電圧Ｖｎレベルは、高い順から繰り出し片、検出対象物なし、各金種硬貨の順となる。
これは、硬貨のように強い磁性を有しない材質から成る検出対象物が検出コイル７上にある場合に、発振コイル９から発生する磁場をこの検出対象物が遮る状態となり、検出コイル７上に検出対象物が何も無い場合よりも、直流変換器１４から出力される電圧Ｖｎのレベルが低くなるものである。
【００１０】
これに対し、繰り出し片３の素材は強磁性体である鉄から成り、この繰り出し片３が検出コイル７上にある場合には、受振コイル１０が検出コイル７上に検出対象物がなにも無い場合よりもさらに磁場を受け易く、したがって直流変換器１４から出力される電圧Ｖｎのレベルもこの時が最も高くなる。
なお、各金種硬貨においてもその材質、外径の違いから電圧Ｖｎに違いが出ることになり、当然、前記ＲＯＭ１８に記憶される金種別基準硬貨データＤａもその金種によって異なることになる。
以上の理由によって、硬貨１の検出コイル７の上からの移動に代わって繰り出し片３が該検出コイル７上へ移動してくるとその電圧Ｖｎは上昇し、検出コイル７上を前記繰り出し片３が完全に覆う時が、硬貨１枚の繰り出し動作中における電圧Ｖｎの最高値Ｖｍａｘとなる。
このことからＣＰＵ１６は、硬貨１枚の繰り出し動作（Ｔ１〜Ｔ２）において供給される検出データＤｎをＲＡＭ１７に記憶するとともに、この記憶された検出データＤｎの最高値を求め、この検出データＤｎの最高値がＲＯＭ１８に記憶される基準繰り出し片データＤｃの領域内にあれば、繰り出し片３が検出コイル７上に架かる位置まで移動したことが確認でき、これによって硬貨の繰り出し動作が確実に行なわれたと判断することができる。
さらに、繰り出し片３の先端が図１の一点鎖線に示す硬貨収納筒２を貫通する位置に達した後、再び硬貨の繰り出し開始／終了位置方向に移動して、繰り出し片３が検出コイル７上から待避すると電圧Ｖｎは低下し、この硬貨収納筒２内に次に繰り出す予定の硬貨１がある場合には、繰り出し片３の先端が硬貨収納筒２から抜き取られ硬貨の繰り出し開始／終了位置に達すると、次に繰り出す予定の硬貨が検出コイル７上に落ち込み、検出コイル７上を覆うため検出対象物が無い時よりもさらに電圧Ｖｎが低下することになる。
したがって、硬貨１の繰り出し動作終了時Ｔ２以降の任意の検出データＤｎを抽出すれば、次に繰り出される予定の硬貨、つまりは繰り出す硬貨を検出した時の検出データＤｎの最も低い値となる検出データＤｎの最低値（図３に示す電圧Ｖｍｉｎ）を抽出することができる。
【００１１】
これによりＣＰＵ１６は、抽出した検出データＤｎの最低値とＲＯＭ１８に記憶される金種別の硬貨基準データＤａ、検出対象物無しデータＤｂ、基準繰り出し片データＤｃとを比較し、該検出データＤｎの最低値が、その硬貨収納筒２に応じた金種の基準硬貨データＤａの範囲内にあれば、ＣＰＵ１６は硬貨収納筒２内の次に繰り出す予定の硬貨１は適正硬貨であると判断し、その金種における繰り出し枚数が残っている場合には、次の繰り出しの動作を開始させる。
さらに、前記検出データＤｎの最低値が、ＲＯＭ１８に記憶される硬貨収納筒２に応じた金種以外の基準硬貨データＤａの範囲内にあれば、ＣＰＵ１６は、次に繰り出される予定の硬貨１は異金種硬貨であると判断し、その金種における繰り出し枚数が残っている場合であっても、その繰り出し動作を中断してこの異金種硬貨を繰り出さないようにし、既に繰り出された適正な硬貨にその検出した異金種硬貨が混入しないようにするとともに警報信号を出力して、図示しない上位機あるいは表示部に異金種硬貨が混入していることを表示させたり警報を発生させる。
また、前記検出データＤｎの最低値がＲＯＭ１８に記載される検出対象物無しデータＤｂの範囲内にあれば、ＣＰＵ１６は硬貨収納筒２内に硬貨１が無いと判断し、警報信号を出力して、図示しない上位機あるいは表示部にその金種の硬貨収納筒２に硬貨１が無い旨を表示させたり警報を発生させる。
また、前記検出データＤｎの最低値が、ＲＯＭ１８に記憶される基準繰り出し片データＤｃの範囲内にあれば、繰り出し動作が終了したにもかかわらず、繰り出し片３が検出コイル７上にあることになるため、警報信号を出力し図示しない上位機あるいは、表示部に繰り出し動作不良が発生したことを表示させたり警報を発生させる。
さらに、前記検出データＤｎの最低値が、ＲＯＭ１８に記憶される金種別の硬貨基準データＤａ、検出対象物無しデータＤｂ、基準繰り出し片データＤｃのいずれの範囲にも無ければ、これら検出対象物である各金種硬貨、検出対象物なし、繰り出し片３のいずれでもない異物が硬貨収納筒２内に混入したものと判断して、警報信号を出力し、図示しない上位機あるいは表示部に異物が混入した旨を表示させたり警報を発生させる。
【００１２】
次に、本発明に係る収納硬貨判別装置の第２の実施の形態について以下に説明する。
なお、第１の実施の形態と同様の構成となる部分については、同様の符号を付しその説明を省略する。
図５は第２の実施の形態に係る硬貨繰り出し装置Ａの概略構成を示す図であり、この第２の実施の形態においては、前記第１の実施の形態における繰り出し確認センサ６を設けず、また、検出コイル７の検出位置を、硬貨収納筒２から繰り出される硬貨１の通過を検出可能な位置で、かつ繰り出し片３が繰り出す硬貨１を最も押し出した時に該繰り出し片３を検出可能となる位置に設けた構成を成す。
以下に、上記構成における本件発明に基づく実施の形態の作用について説明する。
図６は、このような構成における硬貨１枚の繰り出し時の電圧Ｖｎの推移をグラフにしたものであり、その縦軸が電圧レベルＶ、横軸が時間Ｔとなる。
この図６に示すように、硬貨１の繰り出し開始時Ｔ１における硬貨収納筒２内の最下部の硬貨１は検出コイル７上に無いため、その時点における電圧Ｖｎは第１の実施の形態の図４に示す検出対象物無しのときのレベルにある。
しかしながら、繰り出し片３によってこの最下部の硬貨１が硬貨収納筒２外に押し出されるにつれ、該硬貨１が徐々に検出コイル７上を覆うとともにその電圧Ｖｎに変化が生じる。
即ち、上述するように検出コイル７上を繰り出し片３によって押し出された硬貨１が通過すると、その硬貨１による磁場の遮断量に応じてその直流変換器１４から出力される電圧Ｖｎは低下し、該検出コイル７上を完全に覆うとその電圧Ｖｎは硬貨１枚の繰り出し動作において最も低いレベルとなるＶｍｉｎまで達する。
さらに、硬貨１が検出コイル７上を通過するに従い再び徐々に電圧ｖｎが上昇するとともに、該硬貨１を押し出す繰り出し片３が検出コイル７上に架かると、電圧Ｖｎは硬貨１が無い時のレベルを越えてさらに上昇し続け、図５の一点鎖線に示すように該繰り出し片３が検出コイル７上を完全に覆うと、その電圧Ｖｎは、硬貨１枚の繰り出し動作における電圧Ｖｎの最も高い値となるＶｍａｘに達し、この繰り出し片３が再び繰り出し動作開始／終了位置方向に戻ると、その電圧Ｖｎは徐々に低下して、硬貨１枚の繰り出しが終了した時点Ｔ２における電圧Ｖｎは、検出コイル７上に検出対象物が無い時のレベルとなる。
このことから、ＣＰＵ１６は、硬貨１枚の繰り出し動作（図６に示すＴ１〜Ｔ２）において供給された検出データＤｎをＲＡＭに記憶するとともに、この記憶した検出データＤｎの最低値および最高値を検出し、該検出データＤｎの最低値とＲＯＭ１８に記憶される基準硬貨データＤａ及び検出対象物無しＤｂ、基準繰り出し片データＤｃとを比較して、該検出データＤｎの最低値が、その硬貨収納筒２に応じた金種の基準硬貨データＤａの範囲内にあれば、その繰り出された硬貨１が適正な硬貨であると判断する一方で、該硬貨１が繰り出されたことを確認することも可能となる。
【００１３】
つまり、第２の実施の形態では、硬貨収納筒２から繰り出された硬貨１の通過を検出可能な位置に検出コイル７を設けているため、繰り出された硬貨１の判別を可能とするとともに硬貨１が繰り出されたことを確認でき、これによって前記第１の実施の形態のように、硬貨１の繰り出しを確認するための繰り出し確認センサ６を設ける必要がなくなることになる。
さらに、前記検出データＤｎの最低値が、ＲＯＭ１８に記憶される硬貨収納筒２に応じた金種以外の基準硬貨データＤａの範囲内にある場合には、繰り出された硬貨１が異金種硬貨であると判断して警報信号を出力し、図示しない上位機あるいは表示部に異金種硬貨を検出した旨を表示させたり警報を発生させる。
また、前記検出データＤｎの最低値が、ＲＯＭ１８に記憶される検出対象物無しデータＤｂの範囲内にある場合には、硬貨収納筒２から硬貨１が繰り出されなかったと判断して警報信号を出力し、図示しない上位機あるいは表示部に繰り出し不良があった旨を表示させたり警報を発生させる。
なお、この場合には、硬貨収納筒２内に繰り出す硬貨１がなくなったか、あるいは硬貨収納筒２内に硬貨１があるにもかかわらず、実際には繰り出されなかったことの場合が考えられ、これらの状態を確実に区別して判断できるようにするため、後述する第３の実施の形態を採ることも可能である。
一方、前記検出データＤｎの最低値が、ＲＯＭ１８に記憶される基準繰り出し片データＤｃの範囲内にある場合には、繰り出し動作が終了したにもかかわらず、繰り出し片３が検出コイル７上にあることになるため、警報信号を出力し、図示しない上位機あるいは表示部に繰り出し動作不良が発生したことを表示させたり警報を発生させることも出来る。
さらに、前記検出データＤｎの最低値が、ＲＯＭ１８に記憶される金種別の硬貨基準データＤａ、検出対象物無しデータＤｂ、基準繰り出し片データＤｃのいずれの範囲にも無ければ、異物が繰り出されたものと判断して警報信号を出力し、図示しない上位機あるいは表示部に異物が混入した旨を表示させたり警報を発生させる。
また、ＣＰＵ１６は、検出データＤｎの最高値とＲＯＭ１８に記憶される基準繰り出し片データＤｃとを比較して、該検出データＤｎの最高値が基準繰り出し片データＤｃの範囲内にあれば、その硬貨１の繰り出し動作が行なわれたものと判断する。
【００１４】
次に、本発明に係る収納硬貨判別装置の第３の実施の形態について以下に説明する。
図示は省略するが、第３の実施の形態では、検出コイル３を、前記第２の実施の形態のように硬貨収納筒２から繰り出される硬貨１の通過を検出可能、かつ、硬貨収納筒２内に硬貨１が存在する時、少なくともその最下部の硬貨１の一部を検出可能となる位置に設けるものである。
つまり、前記第１の実施の形態で示す位置（図１参照）と、第２実施の形態で示す位置（図５参照）とのほぼ中間位置に検出コイル７を設け、硬貨収納筒２内に硬貨１が存在する時には、検出データＤｎは、金種別の基準硬貨データＤａと検出対象物無しデータＤｂの中間レベルを示すようにする。

なお、この他に、硬貨１の繰り出し動作開始時Ｔ１以前の任意の検出データＤｎと硬貨１の繰り出し動作終了時Ｔ２以降の任意の検出データＤｎを比較して硬貨収納筒２内の硬貨１の有無を確認することも可能である。

つまり、硬貨収納筒２に混入可能な異金種硬貨は、その硬貨収納筒２に応じた金種硬貨よりも小径の金種硬貨のみであるため、比較対象となる基準硬貨データＤａもこれら混入可能な金種に応じた基準硬貨データＤａだけに限定しても良い。
さらに、比較対象となるデータをその硬貨収納筒２に応じた金種の基準硬貨データＤａだけに限定して判断しても、少なくともその検出した硬貨１が適正硬貨であるか否かを判断することは可能である。（したがって、不適性硬貨と判断した場合には、異金種硬貨と判断するようにしても良い。）
また、請求項における「検出データ」は第１〜第３の実施の形態における「検出データＤｎの最低値」を示すものであり、「硬貨有無検出データ」は第３の実施の形態における「硬貨の繰り出し動作が行なわれていない時の任意の検出データＤｎ」を示し、「繰り出し片データ」は第１〜第３の実施の形態における「繰り出し動作中における検出データＤｎの最大値」を示し、「磁気検出手段」は第１〜第３の実施の形態における「検出コイル７」、「発振器１１」、「受信器１２」、「増幅器１３」、「直流変換器１４」、「Ａ／Ｄコンバータ１５」を示し、「検出データ記憶手段」は「ＲＯＭ１８」、「制御手段」は「ＣＰＵ１６」、「ＲＡＭ１７」を以って示している。
さらに、前記第１〜第３の実施の形態における判別においては、電圧ＶｎをＡ／Ｄ変換したデータ（検出データＤｎ）を比較対象としたが、当然このＡ／Ｄ変換する前の電圧Ｖｎを比較対象としてもよく、したがって請求項で述べた各データはＡ／Ｄ変換する前の電圧の意味を含むものである。

BEST MODE FOR CARRYING OUT THE INVENTION
A first embodiment of a stored coin discriminating apparatus in a coin processor according to the present invention will be described with reference to FIGS.
FIG. 1 shows a schematic configuration of a coin dispensing apparatus A for a specific denomination of a coin processing machine which is an example of the present invention. The coin dispensing apparatus A according to the number of denominations handled in the coin processing machine. Having.
Therefore, the following description focuses on the configuration of the coin feeding device A for this one denomination.
The coin dispensing apparatus A has an inner diameter corresponding to a denomination coin, and includes a coin storage cylinder 2 in which stored coins 1 are vertically accumulated, and one coin 1 stored in the coin storage cylinder 2. It is composed of a feeding mechanism (not shown) for feeding.
The coin storage cylinder 2 has a delivery piece hole 4 at a lower portion thereof, through which a delivery piece 3 described later can be inserted into the coin storage cylinder 2, and a coin 1 to be fed and formed on the opposite side at the same height position as the hole. A feeding hole 5 through which a sheet can pass and a detection coil hole 8 formed at the bottom of the coin storage tube 2 and having a size into which a detection coil 7 described later can be inserted are formed.
In the vicinity of the coin storage tube 2, the lowermost portion which is provided at the same height as the payout hole 4 and is inserted into the payout piece hole 4 of the coin storage tube 2 and stored in the coin storage tube 2. A pay-out piece 3 is provided for paying out the coins 1 from the pay-out hole 5 one by one to the outside of the coin storage tube 2, and the pay-out piece 3 constitutes a part of the pay-out mechanism (not shown). .
The position indicated by the solid line in FIG. 1 is the start / end position of the feeding operation of the feeding piece 3.
Further, on the payout hole 5 side of the coin storage cylinder 2, a payout confirmation sensor 6 composed of a light emitting / receiving element capable of detecting the passage of the coin 1 fed out of the coin storage cylinder 2 by the supply piece 3 is provided. Have been.
Further, when the coin storage cylinder 2 is set on the machine body B, the detection coil hole 8 is formed at the same position as the inner bottom of the coin storage cylinder 2 at the position of the detection coil hole 8. A detection coil 7 for detection is provided through a detection coil hole 8.
[0007]
FIG. 2 is a block diagram showing a configuration of a stored coin discriminating apparatus for a single denomination in the coin processing machine according to the first embodiment of the present invention.
The detection coil 7 includes an oscillating coil 9 and a receiving coil 10 provided in parallel with the inner bottom surface of the coin storage cylinder 2. The oscillating coil 9 is supplied with an alternating current from an oscillator 11. A magnetic field is generated, and when the magnetic field is received by the receiving coil 10, an induced voltage e is generated from the geophone 12. The induced voltage e is amplified by the amplifier 13 and rectified and smoothed in the DC converter 14. The A / D converter 15 converts the voltage Vn into a digital signal (detection data Dn) and supplies the digital signal to the CPU 16.
The CPU 16 receives the detection data Dn or the signal from the feed-out confirmation sensor 6, records necessary information in the RAM 17, and performs processing such as feeding out coins based on a control program stored in the ROM 18.
As described above, in the coin processor, although not shown, in the coin processor, the detection coil 7, the oscillator 11, the receiver 12, the amplifier 13, the DC converter 14, the A / D converter 15, The feeding confirmation sensor 6 is provided, and the CPU 16 receives these signals in advance according to the denomination corresponding to the coin storage cylinder 2.
Also, signals such as a withdrawal command and a withdrawal amount from an operation unit (not shown) or a higher-level device are supplied to the CPU 16 via the I / O interface 19.
Further, in the ROM 18, reference coins are provided in which arbitrary detection data Dn obtained by A / D-converting the voltage Vn when each denomination coin is present on the detection coil 7 by the A / D converter 15 has an allowable range ± △. Detection in which an allowable range ± △ is provided for data Da and arbitrary detection data Dn obtained by A / D converting the voltage Vn in the case where there is no detection target on the detection coil 7, that is, when there is no coin 1 in the coin storage cylinder 2. The object-free data Db and the reference feed piece data Dc in which the detection voltage Dn when the feed piece 3 is present on the detection coil 7 is subjected to A / D conversion and the optional feed data Dn is provided with an allowable range ± △ are stored in advance. The CPU 16 compares the detection data Dn extracted as necessary with the reference coin data Da, the detection object absence data Db, and the reference feeding piece data Dc to make an appropriate determination.
Note that the detection data Dn is based on the assumption that the detection target 7 completely covers the detection coil 7.
[0008]
Next, the operation of the present embodiment in the above configuration will be described.
First, when a withdrawal command and amount data are received from a higher-level machine or an operation unit (not shown), the number of payouts of each denomination is calculated based on the amount data. Of the coin feeding device A is driven according to the above, the feeding operation of the lowermost coin in the coin storage cylinder 2 by the feeding piece 3 is performed by the feeding piece 3, and the feeding check sensor 6 detects the fed coin. When 1 is confirmed, the payout number for the denomination is decremented by one, and the payout operation for one coin is repeatedly performed until the payout number for the denomination is exhausted.
Then, the CPU 16 extracts any data (detection data D1) before starting the feeding operation of one coin of each denomination from the supplied detection data Dn, and stores the detection data D1 and the ROM 18. By comparing the denomination reference coin data Da and the detection object absence data Db, the state in the coin storage cylinder 2 is determined, and necessary control is performed based on the determined result.
Hereinafter, the coin feeding operation of a specific denomination and the transition of the detection data Dn supplied to the CPU 16 will be specifically described with reference to FIGS.
FIG. 3 shows that, in the coin feeding operation, the detection data Dn is A / A on the assumption that both the coin to be fed and the coin to be fed next are appropriate coins according to the coin storage cylinder 2. The graph shows the transition of the voltage Vn before the D-conversion, in which the vertical axis represents the voltage V and the horizontal axis represents the time T.
First, as described above, when the dispensing operation is started T1 on the assumption that the coin to be dispensed is an appropriate coin corresponding to the denomination, the dispensing piece 3 is moved from the position outside the coin storage cylinder 2 shown in FIG. The coin enters the coin storage cylinder 2 and pushes out the lowermost coin 1 in the coin storage cylinder 2.
[0009]
When the feeding piece 3 enters the coin storage cylinder 2 and pushes out the coin 1, the feeding piece 3 moves on the detection coil 7 in place of the pushed-out coin 1. Changes in the voltage Vn output from.
The change in the voltage Vn is caused by a gradual change of the detection target covering the detection coil 7. The difference between the voltages Vn of the different detection targets is shown in a graph of FIG. Become.
As shown in the graph of FIG. 4, in the coin feeding operation, the detection coil 7 is covered, that is, the detection target can be detected when each denomination coin is present on the detection coil 7 and when the feeding piece 3 is provided. Furthermore, there is a case where there is no detection target on the detection coil 7, and in such a case, the voltage Vn level is in the order of the payout piece, no detection target, and each denomination coin in descending order.
This is because when a detection target made of a material that does not have strong magnetism such as a coin is on the detection coil 7, the magnetic field generated from the oscillation coil 9 is blocked by the detection target. The level of the voltage Vn output from the DC converter 14 is lower than when there is no detection target.
[0010]
On the other hand, the material of the feeding piece 3 is made of iron, which is a ferromagnetic material. When the feeding piece 3 is on the detection coil 7, the receiving coil 10 moves on the detection coil 7 without any object to be detected. It is more susceptible to a magnetic field than without it, and therefore the level of voltage Vn output from DC converter 14 is also highest at this time.
Note that the voltage Vn also differs depending on the material and outer diameter of each denomination coin, and the denomination standard coin data Da stored in the ROM 18 also differs depending on the denomination.
For the above reason, when the feeding piece 3 moves onto the detection coil 7 in place of the movement of the coin 1 from above the detection coil 7, the voltage Vn thereof rises and the feeding piece 3 moves on the detection coil 7. Is completely covered, the maximum value Vmax of the voltage Vn during the feeding operation of one coin.
From this, the CPU 16 stores the detection data Dn supplied in the coin feeding operation (T1 to T2) in the RAM 17, obtains the maximum value of the stored detection data Dn, and obtains the maximum value of the detection data Dn. If the value is within the area of the reference feeding piece data Dc stored in the ROM 18, it can be confirmed that the feeding piece 3 has moved to a position over the detection coil 7, and that the coin feeding operation has been reliably performed. You can judge.
Further, after the leading end of the feeding piece 3 reaches a position penetrating the coin storage cylinder 2 shown by the one-dot chain line in FIG. 1, it moves again toward the coin feeding start / end position, and the feeding piece 3 is placed on the detection coil 7. The voltage Vn drops when the coin 1 is retracted, and when there is a coin 1 to be fed next in the coin storage cylinder 2, the tip of the feeding piece 3 is withdrawn from the coin storage cylinder 2 and moved to the coin feeding start / end position. When it reaches, the coin to be advanced next falls on the detection coil 7 and covers the detection coil 7, so that the voltage Vn is further reduced than when there is no detection target.
Therefore, if any detection data Dn after the coin feeding operation end time T2 is extracted, the coin to be fed next, that is, the detection data which becomes the lowest value of the detection data Dn when the coin to be fed is detected. The minimum value of Dn (voltage Vmin shown in FIG. 3) can be extracted.
[0011]
Accordingly, the CPU 16 compares the lowest value of the extracted detection data Dn with the coin reference data Da, the no-detection object data Db, and the reference feeding piece data Dc stored in the ROM 18 for each denomination, and determines the lowest value of the detection data Dn. If the value is within the range of the standard coin data Da of the denomination corresponding to the coin storage cylinder 2, the CPU 16 determines that the coin 1 to be advanced next in the coin storage cylinder 2 is a proper coin. If the number of payouts in the denomination remains, the operation of the next payout is started.
Further, if the minimum value of the detection data Dn is within the range of the reference coin data Da other than the denomination corresponding to the coin storage cylinder 2 stored in the ROM 18, the CPU 16 determines that the next coin 1 to be fed out is Judging that the coin is a different denomination coin, even if the number of payouts in the denomination remains, interrupt the dispensing operation so as not to feed out the different denomination coin, and The detected coin of the different kind is prevented from being mixed into the coin, and an alarm signal is output to display that the different kind of coin is mixed on a higher-level device or a display unit (not shown) or to generate an alarm.
If the minimum value of the detection data Dn is within the range of the detection object absence data Db described in the ROM 18, the CPU 16 determines that the coin 1 is not in the coin storage cylinder 2 and outputs an alarm signal. An indication that there is no coin 1 in the coin storage cylinder 2 of the denomination or an alarm is generated on a host machine or a display unit (not shown).
If the lowest value of the detection data Dn is within the range of the reference feeding piece data Dc stored in the ROM 18, it is determined that the feeding piece 3 is on the detection coil 7 even though the feeding operation is completed. For this reason, an alarm signal is output to display an occurrence of a feeding operation failure on a higher-level device (not shown) or a display unit, or to generate an alarm.
Further, if the lowest value of the detection data Dn is not in any of the coin reference data Da, the no-detection object data Db, and the reference dispensing piece data Dc stored in the ROM 18, the detection object D It is determined that a foreign object other than any of the denomination coins, no object to be detected, or any of the feeding pieces 3 has entered the coin storage cylinder 2 and outputs an alarm signal. It displays that it has been mixed and generates an alarm.
[0012]
Next, a second embodiment of the stored coin discriminating apparatus according to the present invention will be described below.
Note that portions having the same configuration as in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.
FIG. 5 is a view showing a schematic configuration of a coin feeding device A according to the second embodiment. In the second embodiment, the feeding check sensor 6 in the first embodiment is not provided, Further, the detection position of the detection coil 7 is a position where the passage of the coin 1 fed from the coin storage cylinder 2 can be detected, and the feeding piece 3 can be detected when the feeding piece 3 pushes out the coin 1 most. A configuration is provided at the position.
Hereinafter, the operation of the embodiment based on the present invention in the above configuration will be described.
FIG. 6 is a graph showing the transition of the voltage Vn when one coin is advanced in such a configuration, in which the vertical axis represents the voltage level V and the horizontal axis represents the time T.
As shown in FIG. 6, since the lowermost coin 1 in the coin storage cylinder 2 is not on the detection coil 7 at the time T1 at which the coin 1 is fed, the voltage Vn at that time is the same as that of the first embodiment. 4 is the level when there is no detection target.
However, as the lowermost coin 1 is pushed out of the coin storage cylinder 2 by the feeding piece 3, the coin 1 gradually covers the detection coil 7 and changes its voltage Vn.
That is, as described above, when the coin 1 pushed out by the feeding piece 3 passes over the detection coil 7, the voltage Vn output from the DC converter 14 decreases according to the amount of magnetic field cut off by the coin 1, When the detection coil 7 is completely covered, the voltage Vn reaches Vmin which is the lowest level in the operation of feeding one coin.
Further, as the coin 1 passes over the detection coil 7, the voltage vn gradually increases again, and when the feeding piece 3 for pushing out the coin 1 is laid over the detection coil 7, the voltage Vn becomes the level when the coin 1 is not present. When the feeding piece 3 completely covers the detection coil 7 as shown by a dashed line in FIG. 5, the voltage Vn becomes the highest value of the voltage Vn in the feeding operation of one coin. When the payout piece 3 returns to the payout operation start / end position direction again, the voltage Vn gradually decreases, and the voltage Vn at the time T2 at which the payout of one coin ends is detected by the detection coil. 7 is the level when there is no detection target on the object.
Accordingly, the CPU 16 stores the detection data Dn supplied in the coin feeding operation (T1 to T2 shown in FIG. 6) in the RAM, and detects the minimum value and the maximum value of the stored detection data Dn. Then, the minimum value of the detection data Dn is compared with the reference coin data Da, the detection object absence Db, and the reference feeding piece data Dc stored in the ROM 18, and the minimum value of the detection data Dn is determined by the coin storage cylinder. If the coin 1 is within the range of the reference coin data Da of the denomination corresponding to No. 2, it is possible to determine that the fed coin 1 is an appropriate coin, and to confirm that the coin 1 has been fed. It becomes.
[0013]
That is, in the second embodiment, since the detection coil 7 is provided at a position where the passage of the coin 1 fed from the coin storage cylinder 2 can be detected, it is possible to distinguish the fed coin 1 and the coin. It can be confirmed that the coin 1 has been paid out, so that there is no need to provide a payout confirmation sensor 6 for confirming the payout of the coin 1 as in the first embodiment.
Further, when the lowest value of the detection data Dn is within the range of the reference coin data Da other than the denomination corresponding to the coin storage cylinder 2 stored in the ROM 18, the fed coin 1 is a coin of a different denomination. Then, an alarm signal is output, and a higher-level device or a display unit (not shown) displays that a different type coin has been detected or generates an alarm.
If the lowest value of the detection data Dn is within the range of the detection target absence data Db stored in the ROM 18, it is determined that the coin 1 has not been advanced from the coin storage cylinder 2 and an alarm signal is output. Then, the fact that there is a feeding failure is displayed on a higher-level device or a display unit (not shown) or an alarm is generated.
In this case, it is conceivable that the coin 1 to be dispensed into the coin storage tube 2 has disappeared, or that the coin 1 has not been actually dispensed even though the coin 1 is present in the coin storage tube 2. In order to be able to reliably distinguish and determine these states, a third embodiment described later can be adopted.
On the other hand, when the lowest value of the detection data Dn is within the range of the reference feeding piece data Dc stored in the ROM 18, the feeding piece 3 is on the detection coil 7 even though the feeding operation is completed. Therefore, it is possible to output an alarm signal to display an occurrence of a feeding operation failure on a higher-level device or a display unit (not shown) or to generate an alarm.
Further, if the minimum value of the detection data Dn does not exist in any of the coin reference data Da, the no-detection object data Db, and the reference feeding piece data Dc stored in the ROM 18, the foreign matter has been fed out. Then, an alarm signal is output, and a message indicating that foreign matter has been mixed is displayed on a higher-level device or a display unit (not shown) or an alarm is generated.
Further, the CPU 16 compares the maximum value of the detection data Dn with the reference feeding piece data Dc stored in the ROM 18, and if the maximum value of the detection data Dn is within the range of the reference feeding piece data Dc, the coin It is determined that the first feeding operation has been performed.
[0014]
Next, a third embodiment of the stored coin discriminating apparatus according to the present invention will be described below.
Although not shown, in the third embodiment, the detection coil 3 can detect the passage of the coin 1 fed from the coin storage cylinder 2 as in the second embodiment, and When the coin 1 exists in the inside, at least a part of the lowermost coin 1 is provided at a position where the coin 1 can be detected.
That is, the detection coil 7 is provided at a substantially intermediate position between the position shown in the first embodiment (see FIG. 1) and the position shown in the second embodiment (see FIG. 5). When the coin 1 is present, the detection data Dn is set to indicate an intermediate level between the reference coin data Da of the denomination and the detection target absence data Db.
Thus, the presence or absence of the coin 1 in the coin storage cylinder 2 is determined by whether or not any detection data Dn when the coin 1 is not fed out (T1 to T2) is within the range of the no-coin data Db. Can be confirmed.
In addition, in addition to the above, arbitrary detection data Dn before the coin feeding operation start time T1 and any detection data Dn after the coin 1 feeding operation end time T2 are compared, and the coin 1 in the coin storage cylinder 2 is compared. It is also possible to confirm the presence or absence.
Further, the other coins in the third embodiment are determined in the same manner as in the second embodiment, and a description thereof will be omitted.
[0015]
As described above, the discrimination of coins of different denominations in the first to third embodiments described above is performed by determining the minimum value of the detection data Dn, the reference coin data Da of each denomination, the detection object absence data Db, and the reference value. The comparison is made with the feed piece data Dc, and the determination is made based on which data range the minimum value of the detection data Dn is. However, the data to be compared may be limited.
In other words, since coins of different denominations that can be mixed into the coin storage cylinder 2 are only denomination coins smaller in diameter than the denomination coin corresponding to the coin storage cylinder 2, the reference coin data Da to be compared is also mixed with these coins. It may be limited to only the reference coin data Da corresponding to a possible denomination.
Further, even if the data to be compared is limited to only the standard coin data Da of the denomination corresponding to the coin storage cylinder 2, it is determined whether at least the detected coin 1 is a proper coin. It is possible. (Thus, if it is determined that the coin is inappropriate, it may be determined to be a coin of a different kind.)
The “detection data” in the claims indicates the “lowest value of the detection data Dn” in the first to third embodiments, and the “coin presence / absence detection data” is the “coin presence / absence” in the third embodiment. , Arbitrary detection data Dn when the feeding operation is not performed, and "feeding piece data" indicates "the maximum value of the detection data Dn during the feeding operation" in the first to third embodiments. The “magnetic detection means” is the “detection coil 7”, “oscillator 11”, “receiver 12”, “amplifier 13”, “DC converter 14”, “A / D converter” in the first to third embodiments. 15 "," detection data storage means "is indicated by" ROM 18 ", and" control means "is indicated by" CPU 16 "and" RAM 17 ".
Further, in the discrimination in the first to third embodiments, data obtained by A / D conversion of the voltage Vn (detection data Dn) is set as a comparison target. The data may be compared, and the data described in the claims include the meaning of the voltage before A / D conversion.
