Claims11
An apparatus for automatically canceling bank notes, comprising a transport system for the singled bank notes and a printing unit integrated into the transport system in the form of an ink jet printer which provides markings on the bank notes to be canceled, characterized by the combination of the following features
- (a) a marking sensor (12a, 12b) disposed behind the ink jet printer (10) in the direction of transport of the bank notes for detecting the presence of cancellation markings (28) on the bank notes (7)
- (b) a control circuit (15) which initiates the appropriate measures intended for incompletely canceled bank notes when the marking sensor (12a, 12b) detects a bank note without, or with insufficient, marking
- (c) a housing (9) surrounding at least the nozzles of the ink jet printer and the marking sensor (12a, 12b) in such a way as to prevent unauthorized access to the transport area between the ink jet printer (10) and the marking sensor.
A method for automatically canceling bank notes, the cancellation being performed by an ink jet printer, characterized in that the cancellation marking is applied on at least one side of the bank note and at least along a track, and in that directly after the cancellation operation the bank note is tested as to the presence of markings, whereby the marking and testing are protected from unauthorized access.
