Abstract
A feeding apparatus includes a pickup roller arranged to pick and feed a medium downstream along a conveying path, a separating roller arranged downstream to the pickup roller for advancing the medium downstream, a brake roller arranged opposite to the separating roller, and a pressing structure arranged opposite to the pickup roller and operable to swing toward or away from the pickup roller according to the rotating direction of the brake roller. When the brake roller rotates for feeding mediums downstream, the pressing structure moves toward the pickup roller and applies a normal force required for picking the medium. But when the brake roller stops rotating downstream because multiple mediums are fed between the brake roller and the separating roller, the pressing structure moves away from the pickup roller and stops applying normal force, so as to control the medium-picking process.
