Document loading for copying
First Claim
1. In an automatic document handling system of a copying apparatus for making pre-collated copy sheet sets by repeated collated imaging of a set of original documents on an elongated windable document holding web having a document supporting side, wherein a spaced pair of oppositely wound scrolls of said web are provided for retaining said documents within said scrolls, wherein said scrolls are normally facing one another and forming a nip with said document supporting side of said web, and wherein said web has a minor intermediate unwound segment extending between said web scroll nip, and wherein means are provided for automatically multiply recirculatingly winding and unwinding said web with the documents thereon through said intermediate segment between one said web scroll and the other said web scroll to multiply recirculatingly expose individual documents on said intermediate segment of said web in a pre-collated order for making said pre-collated copy sheet sets, the improvement in means for loading documents onto said intermediate segment of said web comprising:
- means for selectively repositioning at least one of said web scrolls relative to said intermediate segment of said web into a position providing for the loading of documents onto said document supporting side of said intermediate segment of said web,a scroll shroud means overlying and movable with said one web scroll, and a document loading guide means movable together with said scroll shroud means into a document loading position adjacent said intermediate segment of said web when said one web scroll is so repositioned into said document loading position.

Abstract
Automatic pre-collation document copying in which the documents are loaded upon, and automatically recirculated by, an elongate windable document holding web. A spaced pair of oppositely wound scrolls of the web wind up documents loaded onto the web, where these documents are retained between the turns of the web on both of the scrolls during the copying operation. The web has a minor intermediate unwound segment extending between the two web scrolls where the documents are intermittently exposed for copying by appropriate optical systems for projecting the document images onto a xerographic drum or belt or other imaging surface. A drive is provided for recirculatingly winding and unwinding the web between one web scroll and the other so as to recirculatingly expose, in sequence, the individual documents on the web as they appear on the unwound intermediate web segment. The documents are thereby exposed in the pre-collated order in which they are loaded onto the web, or/and the reverse to produce correspondingly pre-collated copy sets. A document loading guide is movable into a document loading position adjacent the intermediate segment of the web when one web scroll is repositioned into a document loading position.
