1. A medium conveying apparatus comprising:
a loading tray;
a pick roller feeding a medium placed on the loading tray;
a separation roller located on a downstream side of the pick roller in a conveying direction of the medium;
an arm located above a conveyance path of the medium in such a way as to be raised according to a lift of the medium; and
a lift sensor detecting the 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 by detecting a rise of the arm, wherein
an upstream-side edge of the arm is located on an upstream side of a downstream edge of the loading tray, and a downstream-side edge of the arm is located on a downstream side of the downstream edge of the loading tray, in the conveying direction.
