Problems solved by technology

However, it can be predicted that when the same A / D converter is used, once the dynamic range is expanded, the quantization unit of the signal will increase compared with the case where the dynamic range is narrow, and it will be difficult to find subtle features of paper. such problem

Abstract

The invention relates to sheet handling apparatus. An object of the present invention is to increase a capability to determine bills determined as unidentified to improve a truth determination capability. A sheet handling apparatus of the present invention comprises: a detector that detects a characteristic of a sheet transported by a transport module; an amplifier that amplifies a signal obtained from the detector; an A / D converter that converts an analog signal amplified in the amplifier to a digital signal; determining means that determine the truth of the sheet by use of a signal having been produced as a result of A / D conversion by the A / D converter; and a control part that changes signal read accuracy of the detector. If a sheet is determined as unidentified in the determining means, the control part changes an amplification factor or resolution of the detector so that a capability to determine the sheet is higher, and the truth determination of the sheet is performed again.

Description

technical field [0001] The present invention relates to a paper processing device, and in particular to a paper currency processing device which improves the authenticity judgment ability of the paper money among the paper money processing devices such as automatic deposit machines (hereinafter referred to as ATMs) and automatic changers. Background technique [0002] A paper processing device such as an ATM handles several kinds of common banknotes, and the identification unit judges the currency type and authenticity of the banknotes. The banknote judged to be counterfeit by the identification unit is withdrawn from the device and returned to the customer instead of being swallowed into the ATM. On the one hand, in order to identify the users of counterfeit banknotes and ensure that the counterfeit banknotes used are used as evidence, there is an increasing demand not to return counterfeit banknotes to customers. The return type ATM takes out the banknotes deposited by th...
