Two-sided document copying system - has inverting mechanism for turning document over and returning it to imaging station where masters are formed |
摘要 |
<p>The copy system includes a document feeding appts. which is effective to move a document to an imaging station. An image on one side of the document is then projected on an electrostatically charged sheet to form a first master. The document is then transferred to an inverting mechanism which is effective to turn the document over and return it to the imaging station. A second master is then formed. The masters are sequentially transferred to a duplicating section which includes a printing unit. The printing unit utilizes the masters to print on one side of a sheet of material as it passes through a printing nip. During a printing operation, blank sheets are sequentially fed from a supply pile through the printing nip and the first master is utilized to print images on first or front sides of the sheets.</p> |
