Abstract
A sheet feeding device for feding stacked sheets one by one incorporates therein a sheet separator in which a friction pad touching a sheet feeding roller is rocked by one or more sheets passing through between the sheet feeding roller and friction pad, thereby to successfully separate the overlapping sheets. The rocking movement of the friction pad is fulfilled, for example, by providing the pad on its leading end within an uplift protrusion which is forced up by the sheet being contacted therewith. By the action of the friction pad thus rocked, the so-called double-feed phenomenon can be completely prevented.
