ABSTRACT:
Overlapped or folded bills in a paper money dispenser are detected by sensors that measure bill length and thickness. The sensors generate a first signal when bill thickness corresponds to the thickness of at least one standard bill and generate a second signal when bill thickness corresponds to at least twice standard bill thickness. A third signal is generated when bill thickness corresponds to at least three times standard bill thickness. The first and second signals, together with a fourth signal corresponding to the bill length, are supplied to a computer that identifies single or double bills as well as overlapped or folded bills and jammed bills. Bill count is incremented in response to identification of single or dispensable double bills. Overlapped bills, folded bills, double bills that cannot be dispensed, triple bills or suspicious bills are diverted to a storage canister.
