If the storage of the bills in the storage is disturbed, when the bills are dispensed from the storage, the delivery of the bills becomes unstable. Therefore, we have limited the denominations that can be dispensed, such as using small banknotes for deposit only.
- the size inside the storage is adjusted to the bill size.
- the width inside the storage case is adjusted to the width of the bill, which is smaller than the width of the bill transport path.

図11~図14は、実施例1に係る紙幣搬送装置によりセンタリングが行われる場合の一例の概要を示す模式図である。図15は、実施例1に係る紙幣搬送装置によるセンタリングのエラーの一例の概要を示す模式図である。図11に示すケースでは、搬送路7a上を搬送される紙幣2の左端(X軸の負方向の端部)が位置検知センサ32LU及び32LLをセンサ遮蔽するので、紙幣2のセンタリング処理が実行される。このケースは、図9に示すステップS12の判定がNoの場合に該当する。なお、搬送路7a上を搬送される紙幣2の右端(X軸の正方向の端部)が位置検知センサ32RU及び32RLをセンサ遮蔽する場合も、紙幣2のセンタリング処理が実行される。
(1)ローラ12L,12Rのホームポジションへの移動
実施例1では、搬送路7a上における紙幣2のセンタリング処理を実行前に、ローラ12L,12RのX軸方向の現在位置が正方向(負方向)の限界位置に位置しない場合、ローラ12L,12RをX軸方向の正方向(負方向)の限界位置(第1ホームポジション、第2ホームポジション)まで移動させるとした。しかし、これに限られず、センタリング処理を実行前に、ローラ12L,12RのX軸方向の現在位置が正方向(負方向)の限界位置に位置しない場合であっても、位置検知センサ32LU~32RLによる紙幣2の搬送位置の搬送路7a上における中心からのズレ量が、現在位置からローラ12L,12Rを水平移動させてもセンタリング可能な量であると判定される場合、限界位置までローラ12L,12Rを移動させることなく、現在位置からローラ12L,12Rを水平移動させてもよい。これにより、ローラ12L,12Rをホームポジションへ移動させる処理が省略可能となるため、センタリング処理のさらなる効率化及び高速化を図ることができる。
実施例1では、紙幣搬送装置100は、搬送路7aにおける鑑別部4の下流側かつ一時収容部5の上流側に配置されるとした。しかし、これに限られず、紙幣搬送装置100は、搬送路7aにおける鑑別部4の下流側から収納庫6までのいずれかの位置に配置されるとしてもよい。
実施例1では、ローラ12L,12Rは、2つのローラ12L及びローラ12Rが、所定間隔を空けてシャフト11に軸着されるとした。しかし、これに限られず、3つ以上のローラが所定間隔を空けてシャフト11に軸着されてもよい。
実施例1では、チェックセンサ31LU及び31LL、チェックセンサ31RU及び31RL、位置検知センサ32LU及び32LL、位置検知センサ32RU及び32RL、ホームポジションセンサ60のセンサ類は、光電センサであるとした。しかし、これに限られず、これらのセンサ類は、赤外センサ等、その他のセンサであってもよい。
実施例1では、紙幣搬送装置100は、紙幣取扱装置1内に備えられる構成の1つとした。しかし、これに限られず、紙幣搬送装置100は、紙幣取扱装置1の着脱可能なユニットとして提供されてもよい。
図16は、実施例2に係る紙幣搬送装置の概略の一例を示す斜視図である。実施例2に係る紙幣搬送装置100Aは、実施例2に係る紙幣搬送装置100と比較して、チェックセンサ31LU及び31LL、チェックセンサ31RU及び31RLが省略されている。
図17は、実施例3に係る紙幣搬送装置の概略の一例を示す斜視図である。実施例3に係る紙幣搬送装置100Bは、実施例2に係る紙幣搬送装置100Aと比較して、位置検知センサ32LU及び32LL、位置検知センサ32RU及び32RLが省略されている。
