Patent ID: 7918453

Claim:
A bi-directional media drive apparatus adapted for installation in a substantially rigid supporting structure, the apparatus comprising: at least two pinch rollers, each pinch roller capable of driving media in a transport direction and a reverse direction; and two opposing nip baffle pairs for each pinch roller, each two opposing nip baffle pairs and corresponding pinch roller spaced in relation to each other, each two opposing nip baffle pairs forming a media path through the corresponding pinch roller, the media path crossing the relation between the corresponding two opposing nip baffle pairs and pinch roller, each nip baffle pair including a first part and a second part in interdigitated relation to the first part to facilitate non-stubbing media transfer along the media path, the interdigitated relation between the first and second parts such that the first part separates from the second part of the corresponding nip baffle pair along the relation between the corresponding two opposing nip baffle pairs and pinch roller and crossing the media path, wherein the interdigitated relation between the first and second parts of each nip baffle pair are spaced in relation to each other and the corresponding pinch roller; wherein at least the second part of the nip baffle pairs is movable in relation to the first part of the corresponding nip baffle pair about a pivot point from an extended position for media transfer to a retracted position.
