ABSTRACT:
The sheet feeding device comprises a frame with a fixed receptacle for the sheets and pick-up rollers mounted on a first shaft which is pivotingly fitted on the frame by means of a rocking support device. A second shaft is linked to a motor and bears, by means of two pivotingly mounted support members, the first shaft and the rollers. Two pinions integral with the shafts and an intermediate pinion provided with a braking member allow the rollersto be brought into rotation starting from the shaft. Accordingly, the latter commands rotation of the entire support device and presses the rollers against the uppermost sheet with a surface force which increases when the resistance to movement of the uppermost sheet increases. Extremely reliable paper feeding operation is achieved as a result, with a simple construction method and at low cost.
