Abstract

A sheet feeder including a feeding roller, a separating roller, a separating pad, a pressing device, and a separating plate is provided. The separating roller locates downstream the feeding roller. The separating pad leaning on the separating roller has a curved separating portion. The pressing device has a spherical node. The separating plate has a concave on a back surface thereof for allocating the spherical node, and it also has a V-shaped silt on a front surface thereof for pressing the separating pad on the separating roller. As the spherical node applying force to the separating pad, the V-shaped slit is driven to be parallel to the shaft of the separating roller so as to have the separating pad correctly assembled on the surface of the separating roller.
