Abstract
A cassette for an inked ribbon has a ribbon storage region, in which the ribbon is stored in tightly packed random folds, between two parallel walls spaced apart by a distance slightly in excess of the width of the ribbon. The storage region is bounded by ridges projecting from one or both walls to retain the ribbon within the storage region. This has the advantage compared with side walls for the storage region of lower frictional constraint on the ribbon thereby allowing the ribbon to be more tightly packed in the storage region.
