Title:
SHEET RECIRCULATING APPARATUS
Document Type and Number:
Japanese Patent JPS5492743
Kind Code:
A
Abstract:
A recirculating sheet feeder (10) for a copier/duplicator (12) has an input bin (20) capable of receiving a multiplicity of stacks of original pages requiring processing stack by stack, a page at a time. Control data defining the job to be done for each stack in the input tray is introduced as by a header card placed at the leading end of that stack, or by an operator. All pages of a stack being processed are bottom fed by a drive (24) from the input bin to a processing station (15) and thence to at least one additional bin (27, 28). The pages are subsequently processed for additional copies as required by bottom feeding by another drive (32, 33) from the additional bin and top stacking the copied pages into that same bin or into yet another additional bin (28, 27). Completion of the total number of copies is followed by unloading the original pages from the additional bin(s). Supplementary copying involved in a copy jam recovery is obtained by top feeding the page requiring recopying from the additional bin (27, 28) using the drive (33, 34) after adjustment, the page being recopied at the processing station, and returned to its former place in the additional bin.
