ABSTRACT:
The apparatus is for automatically transporting sheets of original to a reading position on a plane member of an image forming apparatus. The apparatus includes an assembly for setting in position or accommodating sheets of original, an assembly for feeding the sheets, a transporting rolling device and a guiding device. The sheet setting assembly is located beside the plane member. The sheet feeding assembly is for feeding a sheet from the sheet setting assembly. The transporting rolling device presses on the plane member of the image forming apparatus to transport a sheet from the sheet feeding assembly by means of nipping the sheet against the plane member. The guiding device is located at a place adjacent to the transporting rolling device and ahead or upstream of it, with respect to the sheet transporting stream, for guiding the leading edge of the sheet to the nipping position between the transporting rolling device and the plane member. A second guiding device, a discharge guiding device, is positioned upstream of the first guiding device and allows the sheet to pass by it in the feeding direction and acts to guide the sheet when being discharged. The apparatus may be applied to copying machines.
