  • Patent number: 7612558
    Abstract: 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.

  • Patent number: 5998738
    Abstract: An electronic control module (40) includes a base plate (12) bent about first and second major bend axis (27, 28). The base plate includes first and second grooves (29, 30) formed at an upper surface (15a) coextensive with the first and second major bend axis (27, 28). A flexible film (18) is asymmetrically bonded by adhesive films (31, 32) about the first and second major bend axis (27, 28). The asymmetrical bonding of the flexible film (18) about the major bend axis (27, 28) causes non-bonded loop portions (35) of the flexible film (18) to assume a serpentine pattern and deflect away from the major bend axis (27, 28) when the base plate (12) is bent about the major bend axis (27, 28). The bonding arrangement of the flexible film (18) to the base plate (12) permits an electrical connector (36) to be attached to the backside of the electronic control module (40).
