Abstract
A medium feeding apparatus includes an opening unit (a lock shaft, a lock arm, a hopper, a link member, and a rotating member) that performs an opening operation in a direction in which rollers coming into press contact with each other on a conveying path for a medium are separated from each other when a conveyance error of the medium occurs. An error release operation control unit of a controller controls the opening unit by switching whether an opening operation is performed to the degree of opening in which a conveying roller and a driven roller are separated from each other or an opening operation is performed to the degree of opening in which a separating roller and a braking roller are separated from each other, according to an entering distance of the medium on the conveying path.
