    摘要: An apparatus for assessing the condition of a bank note includes a vacuum pump (4), an air flow detector (8) for producing an electrical output indicative of air flow through the detector (8), and a suction device (10) connected to the vacuum pump (4) via the air flow detector (8). In operation, a bank note is fed from an entry slot into cooperative relationship with the suction device (10) such that the bank note covers, and is sucked against, the suction device (10). An electronic control device is coupled to the detector (8) and is arranged to make a determination of the condition of the bank note based on the electrical output of the detector (8), this output being representative of the porosity of that part of the bank note sucked against the suction device (10).
