Abstract
In a paper feeding control device according to a first embodiment of the invention, paper sheets delivered from paper containing sections are stopped once when their ends are detected by a paper detecting means. The paper sheet starts to be fed from the position where it is stopped, and a subsequent paper sheet is delivered at intervals of time corresponding to the minimum spacing required between paper sheets. Accordingly, even if the spacing between sheets is below the minimum because of slipping of the sheets during feeding, the sheets tend not to collide with each other and jamming is less likely. In a second embodiment of the invention, with continuously feeding paper sheets, two conditions are ANDed, namely, the elapse of time corresponding to the ideal spacing with which sheets are fed and the elapse of time corresponding to the minimum spacing required between the sheets. This ANDing is used to control the timing of the feeding of the subsequent sheet. The sheets are thus suitably spaced apart from each other. Accordingly, even if the ends of the sheets are out of line with each other in the paper containing section, or if the sheets are delivered slightly early or slightly late, or if the sheets slip while being fed or coveyed, there is less likelihood of a paper jam.
