Abstract

PURPOSE:To enable the supply of one sheet of paper at a time and automatic separative supply of papers with a simple construction, by providing a protrusion member projected from a guide surface of a guide means toward a groove part of a sheet-feeding roller. CONSTITUTION:On the lower side of a guide surface 40, separating protrusions 41, 42 are projected toward groove parts 30, 31 of a sheet-feeding roller 26. When the roller 26 is started rotating, a bundle of postal cards 45 is drawn in downward by a force F1, and is placed into a gap L3 between the guide surface 40 and a roller part 26b. The bundle of the postal cards tends to be stopped by receiving resisting forces F4 of the protrusions 41, 42, but only the uppermost postal card receiving the force F1 is fed against the forces F4. On the other hand, the second postal card receives only a frictional force F2 from the uppermost postal card 45, so that it can not overcome the resisting forces F4 exerted from the protrusions 41, 42 and can not ride over the protrusions 41, 42. Therefore, the postal cards placed in the gap L3 are sequentially fed in such a manner that only the uppermost sheet is separated and fed at a time.
