ABSTRACT:
A sheet supplying apparatus includes a sheet supply roller provided at its periphery with a cylindrical portion for supplying a sheet and a cut-out portion having a radial distance smaller than a radius of the cylindrical portion, a friction separator moving toward and away from the sheet supply roller to separate sheets one by one when it is contacted by the cylindrical portion of the sheet supply roller, and a biasing mechanism for biasing the friction separator toward the sheet supply roller. In addition, a rotation controller stops the sheet supply roller so that the cut-out portion is opposed to the friction separator when the feeding of the sheet effected by the sheet supply roller is finished, and a guide is arranged for pinching the sheet, which is fed out by a force smaller than a pinching force for pinching the sheet between the cylindrical portion and the friction separator, between the friction separator and the guide when the sheet supply roller is stopped by the rotation controller.
