  • Keyed hub and core for ribbon supply
    Patent number: 6425548
    Abstract: A core/hub assembly for a printing device that provides for easy alignment and insertion, and maintains a secure interface to prevent slippage of the core during printer operation, is disclosed. A hub includes keys mounted at a proximal end which serve to transmit torque when engaged with a core. The hub further includes splines configured to be received within a core and provide longitudinal support thereto. A core includes a plurality of longitudinally extending ribs that cooperate to form channels configured to receive the splines of the hub. A portion of the ribs include compliant radially oriented leaf springs which center the core on the hub and provide a physical fit of the core on the hub by engaging the keys at the proximal end of the core when properly inserted therein.
