Problems solved by technology

In the case of such a bonded note, if one were to identify the media purely based on the thickness of the tape, it would be difficult to reliably identify the bonded note since the thickness of the line window pattern cannot be distinguished from the thickness of the tape.

Abstract

The present invention provides a medium recognization device, capable of recognizing whether an application ticket pasted with an adhesive tape based on thickness data corresponding medium safety line part, and capable of recognizing whether the safety line part is pasted with the adhesive tape or not reliably even though the medium with a line window pattern being formed on the safety line. The medium recognization device includes a thickness data obtainment part, for obtaining thickness data detected by a thickness detection sensor of each channel corresponding to each part of the medium; a line part thickness data obtainment part, for obtaining the line part thickness data corresponding to the safety line part of the medium from the thickness data; a thickness data analysis part, for calculating the variance of the line part thickness data; and a judgment part, for judging whether the safety line part is pasted with the adhesive tape or not by comparing the calculated avariance with a prescribed decision threshold.

Description

technical field [0001] The invention relates to a medium identification device. Background technique [0002] Conventionally, automatic transaction devices such as ATMs (Automatic Teller Machines: automatic cash deposit machines) and CDs (Cash Dispensers: automatic cash dispensers) installed in branches of financial institutions such as banks, credit unions, post offices, and consumer finance companies Or currency exchange machines, and automatic vending machines installed in shops or on the road, etc., are equipped with a medium identification device for identifying the authenticity of a medium such as banknotes and identifying the type of medium. Illegal media such as counterfeit banknotes can be excluded by discriminating the authenticity of media such as banknotes by the media identification device. [0003] In recent years, the circulation of counterfeit banknotes in which counterfeit bills are partially bonded by cutting out a part of the genuine medium, that is, bond...
