Abstract
A ribbon cartridge having a supply spool (3) and a take-up spool hub (27) to receive ribbon (1). A section (49) of a wire (32) extends from the mounting post (33), with its pointed end resting against the take-up hub (27). Movement in the take-up direction causes a sliding action. Attempted unwinding causes the end to dig into the take-up hub (27) so that the wire section (49) immediately prevents unwinding.
