摘要:
An apparatus according to the present invention is provided with a plurality of discriminating blades which are arranged in a cylinder within a rotating drum along an inner peripheral surface thereof, to define a discriminating region, transverse end portions of the discriminating blades being superposed with gaps therebetween, a drive motor which revolves the discriminating blades around the center of the discriminating region, thereby causing those paper sheets which are thinner than the gaps, out of a plurality of paper sheets of different thicknesses in the discriminating region, to pass through the gaps, and a control section which performs control to change a rotating state of the rotating drum driven by the drive motor.
