A medium feeding device 1 includes a separating power generating device 7 which causes a brake roller 4 to generate a rotational load in a direction counter to a conveying direction. The device 7 includes a torque limiter 17 which generates a load of a predetermined upper limit torque T1, a torque limiter 18 which is arranged in series with the torque limiter 17 on a power transmission path to the brake roller 4 and generates a load of an upper limit torque T2 smaller than the torque T1, and an electromagnetic clutch 22 which switches between connection and disconnection between the power transmission path and a bypass route which bypasses the torque limiter 18. The device 7 can change the rotational load of the brake roller 4 to the torque T1 or the torque T2 by the switching of the electromagnetic clutch 22. |
