ABSTRACT:
The present invention relates to a system for issuing tickets and including means for delivering a warning signal when the remaining stock of paper falls below a given number of tickets. To do this, a strip (6) has a special mark on it together reference marks delimiting a length of strip corresponding to one ticket. A sensor (24) detects the passage of the special mark and loads a counter (40). Each time a reference mark goes past the sensor, the contents of the counter (40) is decremented. When a comparator (42) detects that the contents of the counter has reached a predetermined value, it delivers the warning signal.
