Abstract

PURPOSE: To secure repeated feed of the same paper sheet even though an electrostatic attractive force is present in the case of the paper feeder of a both- sides copier, by providing near the paper tray a detector which detects entry of a paper sheet and turns a feed roller for a short time.
CONSTITUTION: A paper sheet 13 with its one side already printed is driven by a feed roller 3 which rotates for a short time in response to a signal from a paper sheet entry detector 16 during the drop of the paper sheet guided by a sheet 15, and stopped with its leading edge located at a retard roller 4, and successively transported paper sheets are thus stacked. Next, when the feed roller 3 is driven, transportation of the lowermost paper sheet 13, is started, while overcoming the adsorptive force generated by the dead weight of paper sheets 13 stacked above the lowermost paper sheet 131 and also by the static electricity. Then, although the paper sheet just above said sheet 131 may be transported simultaneously but this transportation is blocked by the reverse rotation of the retard roller 4 and only the paper sheet 131 is accelerated and transported throug high rotational speed of transport rollers 12. When a paper detector 14 detects the trailing edge of this paper sheet 131 transportation of the next paper sheet is started.
