Problems solved by technology

The many fitness measurements also lead to the fact that fitness checks are often hardly manageable for the user of the device used to perform the fitness check due to the multiple thresholds required for this

Embodiment Construction

[0095] exist Figure 4 A banknote processing machine 1 is shown in , which has an input tray 20 into which banknotes 10 to be processed can be placed, for example banknotes to be separated into negotiable (competent) and non-negotiable (non-negotiable) banknotes. The banknotes 10 are transported individually one by one by the separator 25 to the transport system 30 . The transport system 30 transports individual banknotes through the banknote processing machine, past the metering device 41, and onto one or more output trays 32,34. In this case, banknotes of different suitability can be sorted into different output trays.

[0096] The measuring device 41 contains one or more sensors whose measurement data make it possible to infer the state of the respective banknote, so that the banknote can be evaluated and classified as suitable or unsuitable. The sensor of the measuring device 41 can be, for example, one or more optical sensors with a suitable light source, wherein the se...

Abstract

The invention relates to the fitness testing of value documents. An unfit degree of each value document is determined by means of an unfit function for each of at least two fitness criteria. The unfit function unambiguously assigns each fitness value an unfit degree and comprises two threshold values, beyond which the unfit degree with respect to the relevant fitness criterion is 0 or 1. Between the threshold values there is an uncertainty region, in which the unfit degree lies between 0 and 1 with respect to the relevant fitness criterion and the unfit function runs in a monotonically decreasing or monotonically increasing manner. The unfit degrees of different fitness criteria are subsequently combined to an unfit likelihood of each of the value documents and a fitness classification of each of the value documents is performed on the basis of the unfit likelihood.

Description

technical field [0001] The invention relates to a method and a device for fitness checking of documents of value, such as banknotes, cheques, notes, . . . Fitness check (Fitness prüfung) in the sense of the present application is to be understood on the one hand as a check of the negotiability of used value documents, such as banknotes in circulation, and on the other hand as a check on new value documents Quality checks after their manufacture and before they go into circulation, for example on newly printed banknotes. Background technique [0002] For the fitness check of value documents, it is known to check the value documents by means of sensors and to compare the recorded fitness measurements with threshold values ​​in order to determine whether negotiable (fit) or non-negotiable (incompetent) value documents are A distinction is made between files and, if required, other competency classes, such as ATM competencies. In this case, the user of the device is required t...
