Abstract
Abstract A bill validator assembly is provided that retrofits a coin and token only slot machine to be operable with paper currency. A replacement mounting plate relocates the slot reels and provides space for a bill validator and storage cassette on the interior of the slot machine. An improved stacking drive stacks the bills horizontally for storage within the cassette and minimizes currency jams.
