摘要：
A sheet feeding assembly for separating and feeding sheet material one by one by means of a reversely rotatable separation roller or a stationary friction separation roller. There is further provided a sheet protective roller of which the dimension is substantially equal to that of the separation roller. The protective roller is rotatable freely from the separation roller so that the relative movement of the protective roller may remain unchanged with respect to the feed roller when in use.
