1. A medium conveying apparatus comprising:
a loading tray to place media;
a feed roller to separate and sequentially feed the media placed on the loading tray;
a motor to drive the feed roller;
a sensor located on a downstream side of the feed roller in a medium conveying direction to detect a medium; and
a processor to control the motor, wherein
in a separation period from a start of medium feeding by the feed roller to detection of a front edge of the first medium by the sensor, when feeding a first medium of media placed on the loading tray, the processor controls the motor to rotate the feed roller at a constant speed, and when feeding a second or subsequent medium, the processor controls the motor to rotate the feed roller at a first speed and then at a second speed higher than the first speed.
