Patent number: 7612558Abstract: 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.
