ABSTRACT:
A reciprocating document handler for transporting documents comprising a belt transport supported for transporting sheets in a first and a second, opposite direction. The device further includes apparatus for allowing documents moving in the first and second directions, respectively, at an exchange area on the belt to slide over one another substantially freely. The device includes a pressure member to urge the belt into engaging with transported documents and a mechanism for reducing the bearing of a pressure member proximate the exchange area to promote the substantially free sliding engagement of the documents transported in opposite directions.
