Abstract
A medium feeding device includes a feeding roller that conveys a medium in a conveying direction, and a brake roller that includes rollers that are arranged to be rotatable around one shaft and cause a conveyance load to act on the medium that has entered between the feeding roller and the rollers. The rollers are arranged to press the feeding roller with a predetermined pressure. The medium feeding device further includes a rotational difference generating unit that generates a rotational difference between the rollers so that the conveyance load acting on the medium by the rollers becomes even.
