A reliable, low-cost, easy-to-manufacture sheet delivery or transport device is disclosed, which allows for liberal tolerances and could be used on a large variety of paper transport mechanisms. With reference to Figures 1 and 2, the design was originally prepared in order to take paper, which was exiting from the platen on a printer or typewriter, and forward the paper into an output tray. The trolley housing 11 floats freely on support shaft 12 thereby eliminating any precise alignment requirements. Rollers 15 are supported for rotation in trolley housing 11 by shafts 16. The idler O-rings are positioned around the pair of rollers 15 and rest against a portion of the periphery of the driven pressure roller 13, pressure roller 13 being supported and driven by shaft 17. The sheets of paper travel between the driven pressure roller 13 and the idler O-rings 14, which force the paper against the pressure roller 13 and also compensates for any out -of - roundness or eccentricities between the transporting members. The number of trolley housings 11 and pressure rollers 13 positioned along shafts 12 and 17, respectively, will be determined by the width of paper desired to be handled. Shafts 12 and 17 are supported in a frame assembly (not shown), which provides for adjusting the distance between shafts 12 and 17 thereby adjusting the pressure between O-rings 14 and rollers 15.
