Paper sheet discriminating apparatus, paper sheet processing apparatus, and paper sheet discriminating method

A paper sheet discriminating apparatus comprising:

• a rotating drum;
• a plurality of first discriminating blades which are arranged in a cylinder within the rotating drum along an inner peripheral surface thereof, to define an inside discriminating region which is loaded with a plurality of paper sheets of different thicknesses, transverse end portions of the first discriminating blades being superposed with first gaps therebetween;
• a plurality of second discriminating blades which are arranged in a cylinder along the outside of the first discriminating blades, to define an outside discriminating region, transverse end portions of the second discriminating blades being superposed with second gaps narrower than the first gaps therebetween;
• and
• a drive device which rotates the rotating drum to revolve the first and second discriminating blades, thereby delivering those paper sheets which are thinner than the first gaps, out of the paper sheets of the different thicknesses in the inside discriminating region, into the outside discriminating region through the first gaps and then causing those paper sheets in the outside discriminating region which are thinner than the second gaps to pass through the second gaps.

A paper sheet processing apparatus comprising:

• a feeding device which supplies a plurality of paper sheets of different thicknesses;
• a rotating drum provided on the paper-sheet feeding side of the feeding device;
• a plurality of discriminating blades which are arranged in a cylinder within the rotating drum along an inner peripheral surface thereof, to define a discriminating region which is loaded with the paper sheets of the different thicknesses, transverse end portions of the discriminating blades being superposed with gaps therebetween;
• a drive device which rotates the rotating drum to revolve the discriminating blades around the center of the discriminating region, thereby causing those paper sheets which are thinner than the gaps, out of the paper sheets of the different thicknesses in the discriminating region, to pass through the gaps;
• a control device which performs control to change a rotating state of the rotating drum driven by the drive device;
• a conveying device which conveys the paper sheets delivered from the rotating drum through the gaps between the discriminating blades;
• and
• a sorting/storing device which sorts and stores the paper sheets conveyed by the conveying device, based on sorting information concerned.

A paper sheet discriminating method comprising:

• arranging a plurality of discriminating blades in a cylinder within a rotating drum along an inner peripheral surface thereof, to define a discriminating region, such that transverse end portions of the discriminating blades are superposed with gaps therebetween, and loading the discriminating region with a plurality of paper sheets of different thicknesses;
• rotating the rotating drum by means of a drive device to revolve the discriminating blades around the center of the discriminating region, thereby causing those paper sheets which are thinner than the gaps, out of the paper sheets of the different thicknesses in the discriminating region, to pass through the gaps;
• and
• performing control to change a rotating state of the rotating drum driven by the drive device.
