CIRCULATION TYPE SHEET FEEDER

摘要

PURPOSE:To achieve high speed copying by providing two sheet processing stations or document exposing sections thereby enabling document feed selectively under two modes of document carrying exposure system and fixed document exposure system. CONSTITUTION:The undermost document (O) on a tray 10 is led through sheet separation/carrying mechanism 11 and sheet path 12 to the left of platen glass 1 then carried on a carry belt 13 to predetermined position on the platen glass 1. Upon completion of exposure process, the document is led on the carry belt 13 to the sheet path 14 then returned from the document discharge section 15 onto the tray 10. Here, the platen glass 1 as the first processing station is extended further to the left than the left side of carry belt 13 to use said extended section 1' as second processing station and a reflection board 27 is arranged above said section 1' to realize the purpose.
