Description

【0001】
【発明の属する技術分野】
本発明は磁気センサ押圧装置に係り、特に回転ローラと固定押圧ブロックとを組み合わせてなる磁気センサ押圧装置に関する。
【0002】
【従来の技術】
一般に自動販売機や両替機には、挿入された紙幣の真偽を判別するための紙幣識別機が組み込まれている。紙幣挿入口から挿入された紙幣は、磁気センサの表面を通過する間に紙幣の真偽が判別される。磁気センサのヘッドの対向する側には、回転ローラが配置され、磁気センサを通過する紙幣は回転ローラによって押し付けられ、紙幣の浮き上がりが防止されている。この回転ローラとしては従来ゴムローラが多用されている。
【0003】
しかしながら、この種の従来技術において、磁気センサの回転ローラのローラ表面に汚れや鉄粉が付着した場合、ローラの1回転毎に外乱としての磁気データが検出され、読取り精度に悪影響を及ぼしていた。この問題を解決するために、磁気センサの感磁面に平面状の磁気センサ押え板を押し付ける技術が提案されている(特開平6−333122号公報参照)。
【0004】
【発明が解決しようとする課題】
しかしながら、この先行技術によるときには、皺の多い紙幣が磁気センサと押え板の間に挟み込まれた時に紙幣の搬送が円滑に行われないという問題があった。
そこで、本発明の目的は、上記従来の技術が有する問題を解消し、回転ローラの側に付着したごみや鉄粉の悪影響を受けずに、かつ紙幣を円滑に搬送することができる磁気センサ押圧装置を提供することにある。
【0005】
【課題を解決するための手段】
上記目的を達成するために本発明の磁気センサ押圧装置は、磁気センサと、回転軸に回転可能に嵌装され、上記磁気センサの感磁面に押圧され、両端にフランジ部を有する回転ローラと、この回転ローラのフランジ部の間の環状溝内に一部が装着され、磁気センサの感磁面に押圧される固定押圧ブロックと、前記回転軸を磁気センサに押圧するばね装置とを備えてなることを特徴とするものである。
【0006】
【発明の実施の形態】
以下本発明の実施の形態について添付の図面を参照して説明する。
図1は本発明を紙幣識別機に適用した例を示しており、図において符号1は紙幣挿入口を示し、この紙幣挿入口1に連通して紙幣搬送路2が形成され、この紙幣搬送路2は上部プレート3と下部プレート4との間に形成されている。
上記紙幣搬送路2の上側には、紙幣の真偽を判別するための磁気センサ5が配置され、この磁気センサ5は前面が円曲面の一部によって形成され、磁気感知部が埋設されている。上記磁気センサ5と対向する側には、詳細な構成を後述する磁気センサ押圧装置6が配置されている。
【0007】
上記磁気センサ5の上流には入口搬送ローラ7が設けられ、出口側には出口搬送ローラ8が配置され、これらのローラの間に搬送ベルト9が平行掛けされている。この搬送ベルト9の下側は、紙幣搬送路2の中心を通過するように位置が定められている。
また、入口搬送ローラ7の直下にはピンチローラ10が配置され、出口搬送ローラ8の直下にはピンチローラ11が配置されている。
【0008】
前記磁気センサ押圧装置6は、水平方向の回転軸12を有し、この回転軸12はスプリング部材13,13によって下部プレート4に押し付けられている。また、上記回転軸12の中央部には、回転ローラ14が回転可能に嵌装され、この回転ローラ14は両端にフランジ部14a,14aを有し、これらの間に環状溝14bが形成されている。
【0009】
しかして、上記回転ローラ14には、固定押圧ブロック15が組み合わされている。この固定押圧ブロック15は、図2から明らかなように、半円環部15aとチャンネル部15bとを組合せて閉ループとしたものであり、半円環部15aが回転ローラ14の環状溝14b内に嵌装されている。ここで重要なことは、図4から明らかなように、半円環部15aの先端面と回転ローラ14のフランジ部14aとが一致していることである。また、チャンネル部15bには、支軸16が直結され、この支軸16は固定フレーム17に挿着されている。
【0010】
なお、紙幣搬送路2の入り口には、入口センサ18が設置され、紙幣の挿入を感知して搬送ベルト9を駆動するようになっている。
【0011】
本発明は上記のように構成されているので、紙幣20が挿入口1より矢視方向へ挿入されると、入口センサ18が紙幣を感知し、搬送ベルト9を矢視方向へ回転させる。すると、紙幣20は、入口搬送ローラ7とピンチローラ10との間に差し込まれ、紙幣搬送路2内を矢視方向へ進行し、磁気センサ5と磁気センサ押圧装置6を通過する間に紙幣が真券であるか偽造券であるかが判別される。本発明によれば、回転ローラ14のフランジ部14a,14aによって紙幣20が円滑に引き込まれると共に、固定押圧ブロック15の半円環部15aによって、紙幣20が磁気センサ5の感磁面に押し付けられ、外乱なく安定して紙幣の磁気情報を検出することができる。
なお、上記実施の形態は本発明を紙幣識別機に適用した例を示したが、本発明はこれに限定されるものではなく磁気カード等のカードリーダの磁気センサの押圧装置としても使用可能である。
【0012】
【発明の効果】
以上の説明から明らかなように本発明によれば、磁気センサを押圧する磁気センサ押圧装置が回転ローラと固定押圧ブロック装置とを組み合わせたので、回転ローラに付着したごみや鉄粉による読取り精度が悪影響を受けずかつ紙幣を円滑に搬送できるという効果を期待できる。
