Abstract

An inked ribbon assembly for use with a printing apparatus such as a thermal facsimile machine includes a generally cylindrical supply spool, a generally cylindrical take-up spool, and a sheet-like inked ribbon extending therebetween, with the inked ribbon rolled upon the supply spool and connected to the take-up spool for advancement through the printing apparatus to the take-up spool. The spools of the inked ribbon assembly are rotatably supported in the printing apparatus by support spindles, which effect driven rotation of the supply and take-up spools. The support spindles each include one or more drive lugs which engage the spools of the ribbon assembly for effecting advancement of the inked ribbon. Because the drive lug arrangement of support spindles for different printing apparatus can differ from one model machine to another, the spools of the present inked ribbon assembly have been provided with a specifically configured arrangement of spindle notches which facilitate use of the ribbon assembly in different printing apparatus having differing support spindle configurations.
