- An automatic banknote handling apparatus transmits the banknote number of the collect
- a banknote processing apparatus reads the banknote number of the transferred banknote, and specifies the banknote number from which the read banknote number and the banknote number of the banknote received previously do not correspond.
- Patent Document 1 has a problem that when the banknotes are transferred from the automatic banknote handling apparatus to the banknote handling apparatus, the identification results for the same banknote may differ among the apparatuses. That is, the system described in the above-mentioned Patent Literature 1 specifies bills having the same bill number when the bill is transferred from the automatic bill handling apparatus to the bill processing apparatus. However, it does not guarantee that the identification results such as authenticity for the same banknote match between the devices. For this reason, the situation where the identification result with respect to the same banknote differs may arise. These points apply not only to banknotes, but also to general paper sheets including securities.
- the present invention solves the above-described problem, and a paper sheet discrimination system capable of avoiding, as much as possible, a situation in which identification results for the same paper sheet differ when the paper sheet is transferred from the apparatus to the apparatus.

- the depositing machine, the counting machine, and the organizing machine perform the true / false discrimination of the banknotes.
- the authenticity is determined using the identification set value set for each device. Discriminated. For this reason, the discrimination result with respect to the same banknote does not necessarily correspond in each apparatus.
- Authenticity of banknotes is generally identified based on a magnitude relationship with respect to a preset identification setting value of a detection signal for detecting a predetermined characteristic of the banknote.
- the identification set value is usually set in advance for a predetermined characteristic of a new bill. For this reason, when the authenticity of old banknotes or dirty banknotes is discriminated, for example, even when it is discriminated as authentic by a depositing machine, the detection signal sufficiently reflects the predetermined characteristics of the banknotes compared to the new bill. In other words, since the detection signal does not exceed the identification set value, even if the bill is authentic, it may be distinguished from false.

を含み、
前記第2鑑別部は、
前記第2設定値を基準として前記紙葉類が偽である偽紙葉類と鑑別すると、前記偽紙葉類の前記特定記号に対応付けられた前記第1設定値及び前記第1鑑別結果を前記前工程データから抽出し、
抽出した前記第1設定値及び前記第1鑑別結果に基づき前記第2設定値を緩和するか否かを決定し、
前記第2設定値を緩和すると、緩和された前記第2設定値を基準として前記偽紙葉類の真偽を鑑別するものである。
まず、本発明の基礎となった知見が説明される。従来、例えば流通業の各店舗に設置された入金機等の紙幣鑑別装置において、紙幣の真偽が鑑別され、真正と鑑別された紙幣は、現金センターに移送される。現金センターには、一般に、計数機及び整理機等の紙幣鑑別装置が設置されている。計数機において、紙幣の真偽が鑑別され、真正と鑑別された紙幣が計数される。整理機において、さらに紙幣の真偽が鑑別され、紙幣の正損判別が行われて、金種毎に収納される。正損判別とは、真券と鑑別された紙幣のうち、状態の良い正券と、汚れ、折れ、破れなどの損傷がある損券とを判別することをいう。
以下、本発明の一実施の形態について、図面を参照しながら説明する。なお、各図面において、同じ構成要素には同じ符号が用いられ、詳細な説明は、適宜、省略される。
図1は、本実施形態における紙幣鑑別システム10の構成例を概略的に示すブロック図である。図1に示されるように、本実施の形態における紙幣鑑別システム10は、入金機100と、サーバー装置200と、計数機300と、整理機400とを備える。入金機100は、例えば流通業の各店舗に設置される。サーバー装置200、計数機300、整理機400は、例えば、流通業の現金センターに設置される。
図8は、入金機100の動作例を概略的に示すフローチャートである。例えば、入金機100の投入口に紙幣の束がセットされると、図8の動作が開始される。その後、投入口にセットされた紙幣の束がなくなるまで、図8の動作は、繰り返し実行される。
図9は、計数機300における前工程データ取得手順の一例を概略的に示すフローチャートである。例えば、計数機300の投入口に紙幣の束が新たにセットされると自動的に、又は、計数機300に設けられたスタートスイッチが操作されると、図9の動作が開始される。
以上説明されたように、本実施形態では、計数機300において紙幣が偽と鑑別されたときに、計数機300は、その記番号192の紙幣が入金機100において真正と鑑別されたときの識別設定値TH1、識別余裕値MG1を取得可能に構成されている。そして、識別余裕値/識別設定値が所定値未満のときに、識別設定値TH1を80%の識別設定値TH2に緩和している。したがって、本実施形態によれば、入金機100と計数機300とにおいて、同じ紙幣190に対する真偽の鑑別結果が異なるような事態を可能な限り避けることができる。
(1)上記実施形態の図8の手順では、紙幣が収納カセット140に収納された後で、図8の動作が繰り返し実行されるようになっているが、これに限られない。先に搬送された紙幣に重ならないタイミングで、次の紙幣のための図8の動作が開始されるように構成されてもよい。
