Abstract
A sheet feeding apparatus suitable for use in combination with an imaging system, such as a copier or printer, for feeding sheets of paper one by one to the imaging system is provided. The apparatus includes a predetermined path along which a sheet of paper is transported and a sensor for detecting the presence of a sheet of paper in a predetermined region of the path. When paper jamming of another sheet of paper is detected, if the sensor detects the presence of a sheet of paper in the predetermined region, a controller controls such that the sheet of paper in the predetermined region is transported in the reversed direction so that the sheet of paper is returned to a paper storing section for use in the next cycle of operation. With such a structure, any sheet of paper left unused in the travelling path when paper jamming of another sheet of paper has occurred is automatically returned to its storage so that the operator is not required to remove this unused sheet of paper.
