<p>PURPOSE:To provide a double feeding prevention mechanism which is simple in constitution, high in the freedom degree of layout, and low in cost without requiring any actuator. CONSTITUTION:On a pivot shaft 5a which is integral with the other separate roller 5 corresponding to one separate roller 4 rotated drivingly, a one-way clutch 11 which does not allow the pivot shaft 5a to rotate in sheet feeding direction and allows it to rotate in the reverse direction is mounted. Also, on the one-way clutch 11, a lever body 12 which is made in contact with a sheet riding plate 3a by the upward or downward movement of the sheet riding plate 3a and allows the one-way clutch 11 to rotate in the reverse direction to the sheet feeding direction is mounted.</p> |
