ABSTRACT:
A media detector detects flat media traveling on a transport path formed by a pair of media guides. Light emitted from a light-emitting element enters the first media guide, is reflected within the first media guide, crosses the media transport path between the media guides, is reflected within the second media guide, and exits from the second media guide to a light-sensing element, which converts the light to an electrical signal. The light-emitting and light-sensing elements can be mounted, together with their associated electronics, on a single printed circuit board disposed adjacent to the two media guides, so that no interconnecting cables are necessary.
