The present invention is provided with: a heat source unit; a heat detection unit that detects the intensity of light of a prescribed wavelength obtained from paper sheets in which heat provided from the heat source unit is stored; and a control unit that detects, on the basis of the intensity of the light of the prescribed wavelength obtained from the paper sheets, a repaired paper sheet which has been repaired with a repair member.

Paper sheet handling device

The sensor portion of the bill discrimination device has a variable inductance portion whose inductance changes depending on thickness of the bill and the magnetic ink amount, and an output signal generator for generating an output signal depending on the inductance of the variable inductance portion. The variable inductance portion includes a contact member which may have magnetostrictive behavior, and a coil portion disposed about the perimeter thereof. The contact member is positioned so as to be subjected to pressing force of a spring via an auxiliary roller. When the pressing force received from the spring changes depending on the thickness of a currency bill, the magnetic permeability of the contact member will change and the inductance of the variable inductance portion will change. At the same time, the inductance of the variable inductance portion will also change depending on the magnetic charge of the currency bill.
