Abstract:
A paper money handling device including paper money conveying means for conveying paper money, a wheel connected to one of the ends of a tape, for winding paper money with said tape, a reel connected to the other end of said tape, for rewinding the tape wound on said wheel, wheel driving means for driving said wheel, and reel driving means for driving said reel, said wheel driving means and said reel driving means winding and rewinding said tape between said wheel and said reel when they are driven to thereby wind paper money conveyed from said paper money conveying means with said tape onto said wheel, or rewinding said tape wound on said wheel with paper money to said reel and delivering paper money to said paper money conveying means, said paper money handling device comprising:first pulse detection means for detecting a pulse generated in such a fashion as to correspond to a rotating angle of said wheel; second pulse detection means for detecting a pulse generated in such a fashion as to correspond to a rotating angle of said reel; initial diameter calculation means for calculating an initial diameter of said reel on the basis of an add-up value of the number of pulses detected by said first pulse detection means and an add-up value of the number of pulses detected by said second pulse detection means when a predetermined amount of said tape is wound onto said wheel; moving speed calculation means for calculating a moving speed of said tape by use of the initial diameter of said reel calculated by said initial diameter calculation means; and control means for controlling said wheel driving means and said reel driving means so that the moving speed calculated by said moving speed calculation means reaches a predetermined set speed.
