    • 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.
    • 介质供给装置1包括:分离发电装置7,其使制动辊4沿与输送方向相反的方向产生旋转负荷。 装置7包括产生预定上限转矩T1的负载的转矩限制器17,与制动辊4的动力传递路径上与转矩限制器17串联布置的转矩限制器18,并产生负载 上限转矩T2小于转矩T1,以及电动离合器22,其在动力传递路径和绕过转矩限制器18的旁路路径之间的连接和断开之间切换。装置7可以改变制动辊4的旋转负载 通过电磁离合器22的切换转换为转矩T1或转矩T2。
