Abstract
A medium feeding apparatus comprises a driving motor for moving a backup plate to press a medium against a pickup roller, piezoelectric elements for sensing slippage between the pickup roller and the medium which occurs while the roller rotates, and a controller for driving the driving motor to thereby vary a force for pressing the medium against the pickup roller, when the sensing means has sensed slippage between the pickup roller and the medium.
