Abstract: A printed paper dispensing apparatus for dispensing a predetermined number of printed papers in the form of bank notes, tickets or the like printed matter and a method of controlling the foregoing apparatus. In a case where a required number of bank notes move past abnormal bank note detecting sensors without abnormal bank notes detected thereby so that they are placed one above another in a layered structure on a belt conveyer, all the bank notes on the belt conveyer are conveyed to a dispensing outlet port after a predetermined period of time elapses after the last bank note has moved past the abnormal bank note detecting sensors. In a case where an abnormality is detected with the respective bank notes while they are placed on the belt conveyer in that way, the bank notes are introduced into an abnormal bank note receiving portion.
