A paper passageway delivers bills that have been picked from a bill supply container to a location at which the bills are to be dispensed, the paper passageway and the bill supply container are structurally coupled together at least temporarily to form an integrated bill dispensing structure, and at least one of the bill supply container and the paper passageway are functionally incomplete in the absence of the other. The paper passageway delivers bills alternatively to a location at which the bills are to be rejected, a reject container holds rejected bills in a stack in which the bills are oriented vertically, and the bills are accessible to a user from an open top of the container. The paper passageway and the bill supply container are coupled at least temporarily to form a structure, a picker is positioned within the structure to enable the picker to pick bills from the bill supply container and move them along a predetermined path for delivery to the paper passageway, and the picker is removable from the position within the structure by sliding the picker in a direction perpendicular to the predetermined path. A mounting mechanism supports the bill dispensing structure on a wall through which the bill is to be dispensed to a user, the bill dispensing structure being self supporting and rigid without additional support.
