A medium feeding device 1 includes a feeding roller 3 which conveys a medium S1 in a conveying direction, a brake roller 4 that is arranged to press the feeding roller 3 with a predetermined pressure, and a separating power generating device 7 which is connected to the brake roller 4 and generates rotational load in a direction counter to the conveying direction with respect to the brake roller 4. The separating power generating device 7 includes a torque limiter 19 which generates an upper limit torque T1 which is a fixed load as a first load generating unit, and an electromagnetic brake 23 which can change the generated load as a second load generating unit. The torque limiter 19 and the electromagnetic brake 23 are connected in parallel to the brake roller 4. |
