1. A medium conveying apparatus comprising:
a pick roller to feed a medium;
a separation roller on a downstream side of the pick roller in a conveying direction of the medium;
an arrival detection sensor on a downstream side of the separation roller in the conveying direction to detect arrival of the medium;
a lift sensor to detect a lift of the medium between an upstream side of a roller nip of the pick roller and a downstream side of a roller nip of the separation roller in the conveying direction; and
a processor to
determine that the medium is a bound medium when a lift of the medium is detected by the lift sensor in a first predetermined period after detection of a front edge of the medium in a conveying direction by the arrival detection sensor; and
execute abnormality processing when the medium is determined to be a bound medium.
