<p>UNITED STATE PATENT APPLICATION OF JOHN C. HAMMA SEMI-AUTOMATIC DOCUMENT FEEDER A document feeder is applied to an office copier and includes a base constituting a replacement for the usual platin cover. The base has three sets of sheet engaging rolls spaced along the base to engage a sheet inserted into the housing covering the base to feed the sheet to a position registered for reproduction. Sheets are registered on the platen glass by fingers which are lifted to allow the sheets to be fed from the platen glass. The fingers ride on the successive sheets to automatically intercept the next sheet. The registration fingers are in an assembly mounted on the copier to enable registration of originals when the cover is elevated.</p> |
