Abstract

A note acceptor for validating a paper currency note introduced therein. The acceptor includes a note validator unit and plural, interchangeable nose-pieces for releasable mounting on the validator unit. The validator unit includes a housing having a path extending through it, a conveyor for moving a paper currency note along the path, and plural optical and magnetic sensors to sense features of the note conveyed along the path. The path is of a width sufficient to accommodate the widest of any paper currency note to be validated. Each nose-piece forms a respective entrance port and note-guide to the path in the validator by defining a channel of a predetermined width corresponding to the width of an associated sized paper currency note. By mounting a nose-piece designed for a particular sized paper currency onto the validator housing, the resulting acceptor is configured to handle that size paper currency. When the nose piece is removed the validator is arranged to accept the largest size currency note.
