DEVICE FOR PROCESSING PAPER BANK NOTES AND METHOD FOR DETECTING THE TRANSPORT STATUS OF PAPER BANK NOTES

摘要

The invention provides a method for detecting the conveyance status of a banknote, comprising: detecting whether the banknote reaches a first position in a banknote passage within a first predetermined time after the banknote is determined to be genuine (S12); detecting whether the banknote reaches a second position in the banknote passage within a second predetermined time when it is determined that the banknote has reached the first position (S14), wherein the second position is at the downstream of the first position; determining whether the status of the banknote at the first position is changed from Banknote Detected to Banknote Undetected when it is determined that the banknote has not reached the second position within the second predetermined time (S16); and determining that the banknote is withdrawn when it is determined that the status of the banknote at the first position has changed from Banknote Detected to Banknote Undetected (S18). This application can increase the possibility of the banknote processing device in detecting whether the banknote is withdrawn. Meanwhile, the invention provides a device for processing a banknote.
