Banking machines for dispensing paper currency require a document transport for accurately and reliably delivering a single bill or piece of currency from a storage bin to a customer. The document transport includes a feeder unit for delivering single pieces of currency from a stack to a pair of separator rollers and past a double document detector. Upon detection of more than one document passing through the separator rollers, a clutch is energized to cause one of the rollers to rotate in a direction opposite the other to separate the several bills and allow only the top one to be forwarded into a flat belt transport. As a piece of paper currency passes through the flat belt transport, spaced detectors produce a signal that indicates an overlapping or trailing document condition. This overlapping or trailing condition is measured by the spacing of detectors in the flat belt transport. Further, positioned along the flat belt transport is a second double document detector that again responds to more than one document passing therebetween. If either an overlapping document condition, a trailing document condition, or a double document condition is sensed in the flat belt transport, a divert gate operates to divert all documents from the flat belt transport into a retaining bin. Should the divert gate fail to operate in time to divert a document, the transport belt stops to restrict further document delivery.
