Banknote acceptor feeder device

A banknote feeder device configured to interconnect and operate in conjunction with a banknote acceptor apparatus, the banknote feeder device comprising:

• a banknote input aperture and a banknote output aperture interconnected by a banknote transport conduit, and
• a banknote transport mechanism operable, when the banknote feeder device is connected to said banknote acceptor apparatus, to transport a banknote from said banknote input aperture to said banknote output aperture;
• characterised in that said banknote transport mechanism comprises a linear succession of spaced-apart pairs of transport wheels, wherein each wheel of each said pair of transport wheels extends at least partially through a banknote transport conduit surface into an interior cavity of said banknote transport conduit between the banknote input aperture and the banknote output apertures;
• wherein each wheel of each said pair of transport wheels is mounted eccentrically to a respective common axle of the pair of transport wheels;
• wherein the banknote transport conduit extends in a substantially longitudinal direction of the banknote feeder device, and the banknote transport conduit is delimited in a direction perpendicular to the longitudinal direction by an upper passageway surface and an opposing lower passageway surface;
• wherein the upper passageway surface includes a protrusion extending away from the upper passageway surface towards the lower passageway surface to form a pinch point in the banknote transport conduit;
• wherein the protrusion is located between a pair of resiliently biased guide members;
• and
• wherein each resiliently biased guide member of the pair of guide members is a ski-shaped runner.
