Abstract
A sheet separator for an automatic document feeder of the invention is capable of separating an outmost sheet from a stack. The separator includes a separating roller driven by a driving device, a friction roller, a first shaft, and a force-applying mechanism for pushing the separating and friction rollers against each other. The friction roller has a first rotating state, in which the friction roller is driven by the separating roller, a stationary state when the separating roller feeds a first sheet, and a second rotating state, in which the friction roller is driven by a second sheet fed by the separating roller. The first shaft is inserted into the friction roller to provide a damping torque for stopping the rotation of the friction roller.
