Abstract
A ribbon cartridge includes two hubs, each hub having two sets of longitudinally extending splines. The two sets are offset from each other circumferentially and longitudinally and form a detent between the sets. A latch mechanism includes a retaining member fixed to a mandrel assembly, the retaining member including first and second pairs of elastic locking members having raised surfaces. The raised surfaces of one of the pairs of locking members engage the detent formed between the first and second sets of hub splines, and the raised surfaces of the other pair of locking members engage a spindle of the mandrel assembly, effectively securing the ribbon cartridge to the mandrel assembly.
