| description | A printer ribbon supply spindle assembly is provided. The ribbon spindle has multiple segments contiguous to each other. The spindle assembly includes a commutator disposed circumferentially on the first segment of the ribbon spindle and two carbon brushes connected to a voltage source and disposed generally in electrical contact with and on either side of the commutator. The voltage source, the carbon brushes, and the commutator complete an electrical circuit. C-shaped conductive springs are disposed over each of the multiple segments. The c-shaped conductive springs compress when covered by a printer ribbon and become in electrical contact with the commutator and adjacent compressed c-shaped springs, forming additional parallel circuits. An electronic element is disposed at the center of the c-shaped conductive springs. Measuring a change in the circuit due the additional parallel circuits with the electronic element indicates the printer ribbon width. |
