Abstract
A medium feeding deviceincludes a separating power generating devicewhich causes a brake rollerto generate a rotational load in a direction counter to a conveying direction. The deviceincludes a torque limiterwhich generates a load of a predetermined upper limit torque T, a torque limiterwhich is arranged in series with the torque limiteron a power transmission path to the brake rollerand generates a load of an upper limit torque Tsmaller than the torque T, and an electromagnetic clutchwhich switches between connection and disconnection between the power transmission path and a bypass route which bypasses the torque limiter. The devicecan change the rotational load of the brake rollerto the torque Tor the torque Tby the switching of the electromagnetic clutch
