Abstract

Disclosed are the details of a document handling system intended for use in a xerographic copier/duplicator. The document handling system performs the functions of transporting a document to be copied to the platen of the copier/duplicator, registering the document with respect to the platen, and removing it from the platen. The configuration minimizes the tendency for documents of heavy substance to overshoot the registration edge and for documents of light substance to be buckled and/or creased at the lead edge against the registration edge.

Disclosed are the details of a document handling system intended for use in a xerographic copier/duplicator. The document handling system performs the functions of transporting a document to be copied to the platen of the copier/duplicator, registering the document with respect to the platen, and removing it from the platen. The configuration minimizes the tendency for documents of heavy substance to overshoot the registration edge and for documents of light substance to be buckled and/or creased at the lead edge against the registration edge.

In Figure 1, Numeral 1 represents the glass platen of a copier/duplicator, 2 is a registration edge of unique convoluted shape. Document belt 4 is driven by roller 5 and pressure roller 6, urged against the belt with a force F, insures intimate and uniform contact between the belt 4 and the registration edge.

Figure 2 represents the convolution pattern of the registration edge 2 as indicated at the Section X-X of Figure 1. The shape of the registration edge and the conforming cross section of document belt 4 is shown with exaggerated vertical scale in Figure 2. The actual peak-to-valley dimension may be typically 0.03 inch with a corresponding "wavelength" of 2 inches.

The result of the improvements of this disclosure is to raise the effective height of the registration edge thereby...
