Paper processing device and managing method for paper transmission failure

Abstract

The invention provides a paper processing device and a managing method for paper transmission failure, for the purpose of automatically adjusting threshold value of paper currency and decreasing the transmission failure of paper currency. The paper processing device comprises an identifying part for identifying the state of paper currency, a storage component for classifying the state of paper currency into a plurality of state classifications, storing and managing the quantity of transmission failure of each state classification, and a controlling component for updating the failure occurringtimes of the identified state classification of paper currency managed by the storage component when the paper currency has transmission failures. The controlling component updates the threshold valueof especially classified paper currency when the failure occurring times of one or more state classification is more than a preset value.

Description

technical field [0001] The present invention relates to a paper sheet handling apparatus and a paper sheet conveyance failure management method, and particularly relates to a response to a banknote conveyance failure in an automatic teller machine (ATM). Background technique [0002] When looking at the banknotes of various countries in the world, the material of the banknotes is made of plastic or paper, and there are various differences in the paper quality of the banknotes made of paper. In addition, the banknotes are folded or damaged during circulation, and the state of the banknotes is gradually deteriorated. [0003] If the banknotes in poor condition are accepted at the ATM, the conveyance of the banknotes may become unstable, and a conveyance failure may occur inside the apparatus. In the banknotes in which the conveyance failure occurs, there are various situations such as folding, breakage, and even loss of the toughness of the paper during circulation. Here, th...

AI Technical Summary

Problems solved by technology

However, in order to detect banknotes in an abnormal state, the threshold value of the banknote detection sensor is fixed, so even if the banknotes that can be transported normally at the beginning, if the same ATM is used for a long time, the transport of banknotes in the same state will become unstable. , In the event of a delivery failure

[0009] The technique of Patent Document 2 can suppress fluctuations in defective bills by adjusting the judgment level according to the ratio of good and bad ones. However, since the ratio is used for management, it is not necessarily related to reducing the absolute number of banknote transport failures.
