PURPOSE:To effectively correspond to the change of sucking accompanied by the revolution change, etc., of a vacuum pump with the change of power quality and a voltage fluctuation by determining an off-pressure based on the sucking pressure detected by a pressure converting element. CONSTITUTION:The titled machine provides a pressure converting element (a) to detect the absorbing pressure of an absorbing axis when a bank note is absorbed, an off-pressure adjusting means (b) to determine the off-pressure to be a standard to judge whether the bank note to be sucked to the sucking axis exists or not based on the absorbing pressure detected by this pressure converting element (a) and a counting end discriminating part (c) to stop the driving of the sucking axis when the sucking pressure detected by the pressure converting element (a) is lower than the off-pressure determined by the off- pressure adjusting means and to end the counting of the bank note. The off- pressure, which goes to be the standard to judge whether the bank note to be sucked to the sucking axis exists or not, is suitably fluctuated. Thus, the effective correspondence is executed to the sucking pressure, for example, to fluctuate according to the paper quality of the bank note. |
