ABSTRACT:
The lever of a mechanism for driving a sheet feeder is guided for linear longitudinal movement in a guide member. The guide member is supported rotatably in a bearing pedestal, which is height adjustable. The lower section of the lever is shaped as a hollow profile having inner sliding surfaces. A slide member is located at the sliding surfaces. The slide member receives a pivot, by which a shaft is driven oscillatingly. The slide member is located for longitudinal movement at the center axis of the lever and, accordingly, the lever is not subjected to any torsional loadings and the entire apparatus can be made relatively narrow. This decreases elongations during the operation of the apparatus considerably.
