Abstract
A medium feeding apparatus includes an opening/closing 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 of each of a separator and a conveyor coming into press contact with each other are separated from each other at the time of the occurrence of a conveyance error of a medium and performs a closing operation in a direction in which the rollers come into contact with each other after the recovery of the conveyance error. When an operator is present around the medium feeding apparatus, an error release operation control unit controls the opening/closing unit so that the opening/closing unit performs the opening operation and the closing operation at a relatively low speed as compared to when the operator is not present around the medium feeding apparatus.
