Problems solved by technology

However, the detection of tape is impaired by changes in the detected thickness measurements
Furthermore, detection of adhesive tapes has hitherto been limited when the adhesive tape is very thin and / or the value document itself already has a pronounced thickness profile

Embodiment Construction

[0056] exist figure 1, a document-of-value processing device 10 for sorting documents of value, in this example a device for processing banknotes, is shown. It has a supply device 14 for supplying value documents, an output device 16 for accommodating processed (ie sorted) value documents, and a transport for transferring individual value documents from the supply device 14 to the output device 16 device 18. The feeding device 14 in this example comprises an input device 20 for the value document stack and a picker 22 for picking value documents from the value document stack from the input bag 20 . The output device 16 comprises in this example three output sections 24 , 25 and 26 into which the processed value documents can in each case be sorted according to the processing results. Each output section comprises a stacking bag and (not shown) a stacking wheel, by means of which the supplied documents of value can be deposited in the stacking bag. The conveying device 18 ha...

Abstract

A method for checking value documents is described, wherein measured values ​​of value documents are detected in a spatially resolved manner. The measured values ​​detected at the respective measuring points are associated with the nodes corresponding to said measuring points, from which a two-dimensional network of nodes is formed. A network is formed by a two-dimensional network of nodes and additional source and sink nodes. The document of value is classified as suspected or not suspected of being forged based on the maximum possible traffic traversing the network. The maximum possible flow through the network is a measure of the probability of a value document in a direction transverse to the direction of the network having a continuous object representing a modification of the value document, such as a tape or a separation line from a composed forgery.

Description

technical field [0001] The invention relates to a method for examining documents of value and a corresponding examination device. Background technique [0002] Documents of value are understood to represent, for example, monetary values ​​or authorized sheet-like objects and therefore should not be arbitrarily produced by unauthorized persons. They therefore have a characteristic that is not easy to produce, especially not easy to reproduce, the presence of which is an indication of authenticity, that is, produced by an authorized body. Important examples of such documents of value are chip cards, coupons, receipts, checks and especially bank notes. Documents of value may accordingly differ in their type, for example in the case of bank notes, in their unit or nominal value and circulation, in the case of checks, in the type of check form determined by the issuer of the check different. [0003] Broken or cracked value documents are usually "repaired" with tape. During t...
