Abstract: Connected to the take-up spool (26) of the ribbon cartridge (10) is a disc member (28) supporting a pair of flexible arms (32) with outwardly oriented pointed ends (34). Ends (34) engage ratchet teeth (44) formed on the internal surface of a cylinder (42) forming part of, or attached to, the ribbon cartridge (10). As disc (28) and arms (32) are rotated by the ribbon feed mechanism, arms (32) will flex and permit a rotation of disc (28) and take-up spool (26) with a minimal drag force. Upon reversal, the ends (34) of arms (32) engage ratchet teeth (44) and arms (32) become compression columns resisting the rotation of disc (28) and spool (26). Ends (34) of arms (32) are positioned such that they are one-half tooth out of phase to ensure that one tooth is always in engagement with the end (34) of one of the two arms (32).
