Abstract

PURPOSE:To prevent non-feeding by maintaining the tip section of a paper pressing plate arranged at a separating pad unit guide section in the parallel state at a preset interval from the surface of a document guide. CONSTITUTION:A separating pad unit 13 is constituted of a paper pressing plate 28 fitted by a screw 27 to a transmission door 26 at its upper section, a separating pad 29, its holding plate 30, a pad presser 31 exciting the separating pad 29 to a self-feed roller 14, and a coil spring 32. The paper pressing plate 28 is made of a spring steel plate, and a parallel section 28a with a preset interval is formed at the tip section so that documents 12 are excited with a relatively long stroke to the document guide plate 33 and the axial side of the self-feed roller 14. When an upward warped document 12 is inserted, it is corrected by the parallel section 28a and guided between the separating pad 29 and the self-feed roller 14 to prevent non-feeding, even if multiple documents are vigorously inserted, the vigor is suppressed by the parallel section 28a, and multi-feeding rarely occurs.
