Abstract

A simple and low cost apparatus for ejecting original documents 1 from the platen 2 of a moving (reciprocating) platen copier after they have been copied. The documents are conventionally manually registered on the platen under a cover 3. However, the cover 3 is rigid and spaced approximately 0.04 inches above the platen. The scanning movement of the platen 2 winds up a clock spring motor system 4. At the end of the last scan, i.e. after the selected number of copying scans has been completed for that document at a selected position, as the platen starts to return to its start-of-scan position a control link "M" actuates a cam 5 for a preset time to raise the document registration edge or bar 6 and also cam a foam roll 7 down onto the document 1. The foam roll 7 is then driven by release of the wound-up clock spring. The document 1 is driven under the now raised registration bar 6 and into a deflector 8 and released to an exit tray 9. Thus the platen is automatically cleared for the placement of the next document. That is,
