ABSTRACT:
An original document feeder for copying machines, for automatically positioning originals of any substance on the exposure surface, so avoiding opening and closing the original pressing cover at each change of original, and with a considerable reduction in idle times. The feeder comprises a set of friction rollers of flexible material mounted on a single shaft, these facing each other in a transverse slot so as to compel each original sheet to bend in such a manner as to exert a force against the rollers which is greater the higher the substance or rigidity of the sheets. The feeder is also provided for a device for automatically aligning the originals, and a timer system for coordinating the conveying stages of the originals with the copying machine cycle.
