PURPOSE:To enable letting out one by one sheet as well as to reliably prevent even the sheets of paper with variable thicknesses from two-sheet feeding in such a way that one of one set of rollers for letting out the paper sheets is turned by a driving mechanism, and another is inversely driven by utilizing the resilience of a coil. CONSTITUTION:When a roller 7 is turned, a notch 13 is moved along the surface of a sliding stand 12, it is fed into a recessed part 11 which is provided in the sliding stand 12, and further when the roller 7 is turned, the notch 13 is pushed out of the recessed part 11 and moved. And when the notch 13 is put into the recessed part 11 losing the turning force to the roller 7, the roller 7 is reversely turned by conserved resilience of a coil 16. Thus, when only one sheet of the paper 3 comes in between rollers 5, 7, the paper sheet 3 is let out through the roller 5 to the sides of rollers 9, 10. Besides, when the paper sheets 3 come in one above the other of the two between the rollers 5, 7, by reason that revolution of the roller 7 is stopped by the coil 16, after the paper sheet 3 on the side of the roller 7 is stopped, it is returned to the position before the letting-out by the reversing roller 7. |
