Abstract
The invention provides a stackless continuous dual-sided copying method in photocopying machines. The method includes: a first step of finding as a circulatable sheet count the number of copy sheets that can stay in a circulating conveyance path when performing stackless continuous dual-sided copying; a second step of successively feeding sheets of copy paper wherein the number of the fed sheets is based on the circulatable sheet count if a copy sheet count remaining amount is greater than the circulatable sheet count, and successively convey-introducing the sheets of copy paper into the circulating conveyance path from a copy-sheet conveyance entry point for the circulating conveyance path; and a third step of resuming sheet-feeding operations at a predetermined timing after the last sheet of the copy sheets has finished passing the conveyance entry point in the circulating conveyance path, for starting a next continuous dual-sided copying cycle after copying to first sides of the copy sheets successively convey-introduced into the circulating conveyance path in the second step is completed. Accordingly, when carrying out stackless continuous dual-sided copying in accordance with …
