Abstract

A media transport array for forming sequential media streams feeding a media processing system in which serial flows, parallel flows, or both are desired are structured from standard, batch fabricatable media path modules. Each media path module includes a frame unit, intermodule latching means, media control electronics, and media state sensing electronics. Within each media path module, at least one media transport nip receives media and passes it to an independently actuated media director. Media guides support media as it moves into and out of the media director.

Claims

1. For a media processing system feeding media streams through a media path structured for serial or parallel flows, a media transport array comprising:

not less than two media path modules, wherein each of said media path modules comprises;

a frame unit;

an intermodule latching means;

not less than one media transport nip;

actuation means;

a media director;

media control electronics; and

media state sensing electronics.

2. The media transport array according to claim 1, wherein said latching means comprises at least one interlocking mechanism.

3. The media transport array according to claim 1, wherein said frame unit further comprises signal interconnect means.

4. The media transport array according to claim 3, wherein said signal interconnect means comprises signal pass through connectors which mate during a module joining operation.

5. The media transport array according to claim 1, wherein said not less than one media transport nip comprises not less than one cylindrical nip.

6. The media transport array according to claim 1, wherein said not less than one transport nip comprises not less than one spherical nip.

7. The media transport array according to claim 1, wherein said not less than one media transport nip comprises not less than one piezoelectrically driven brush.

8. The media transport array according to claim 1, further comprising a plurality of media guides.

9. The media transport array according to claim 8, wherein said plurality of media guides comprises not less than two media inlet guides for each said media transport nip.

10. The media transport array according to claim 1, wherein said actuation means comprises not less than one motor drive unit.

11. The media transport array according to claim 1, wherein said actuation means comprises not less than one motor drive unit for each of said media transport nips.

12. The media transport array according to claim 1, wherein said media director further comprises a rotary housing having in-line and deflector means for directing media.

13. The media transport array according to claim 1, wherein said media director further comprises translational deflector vanes with pass through centers for directing media.

14. The media transport array according to claim 13, wherein said translational deflector vanes may be over-retracted.

24. The media transport array according to claim 1, wherein said media control electronics comprise communication electronics.

25. The media transport array according to claim 1, wherein said media director comprises fixed media guide means.

26. The media transport array according to claim 1, wherein said media transport nips are spaced apart uniformly throughout the length of the media path.

27. The media transport array according to claim 1, wherein the spacing between any two of said media transport nips is less than the shortest media length in the process direction.

28. The media transport array according to claim 1, wherein each of said media transport nips within said media path module may be separately actuated.

29. The media transport array according to claim 1, further comprising not less than one extensible transport module having no media director.

30. The media transport array according to claim 29, wherein said not less than one extensible transport module further comprises not less than one transport nip.
