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.
Claims6
A medium feeding apparatus comprising:
- a separating roller that feeds a medium in a conveying direction;
- a braking unit that is disposed so as to come into press contact with the separating roller and applies a predetermined conveying load to the medium entering a gap between the separating roller and the braking unit;
- a conveying roller that is disposed on a downstream side of the separating roller in the conveying direction;
- a driven roller that is disposed so as to come into press contact with the conveying roller;
- and
- an opening unit that performs an opening operation in a direction in which members coming into press contact with each other on a conveying path for the medium are separated from each other when a conveyance error of the medium occurs,
- wherein the opening unit is configured to switch whether to perform a first opening operation to a degree of opening in which the conveying roller and the driven roller are separated from each other or to perform a second opening operation to a degree of opening in which the separating roller and the braking unit are separated from each other, according to an entering distance of the medium on the conveying path.
