Abstract

A ribbon cassette of the kind used to store a reel of typing ribbon, comprises a casing (6), a primary spool (8) mounted an a hub (16) and upon which unused ribbon is wound, and a secondary spool (10) in the casing upon which used ribbon is wound. The secondary spool (10) is provided with means (12) to be engaged by a drive member of (e.g.) a word processor or computer printer, to cause the secondary spool to rotate, and to draw ribbon from the primary spool onto the secondary spool.
The cassette comprises means to resist reverse winding of the primary spool, said means comprising a first toothed ele­ ment (20) forming part of a fixedly mounted on the primary spool, and a secondary toothed element (21) mounted in a diametral slot (24), and which is urged into engagement with the first toothed element (20) by spring means (28). Engage­ ment between the two toothed elements permits normal win­ ding of tape onto the secondary spool from the primary spool, but resists reverse winding of the primary spool.
The spring element (28) engages the ribbon, to maintain tension in the ribbon during use.
Additionally, the ribbon cassette comprises an insert member (80) comprising an operative portion which may be in­ serted through a slot (78) in the base (6) into a position in which it engages the primary spool to prevent rotation thereof during transportation, the insert member comprising a supplementary portion located on the exterior of the casing which may be manually grasped to enable the insert member to be removed from the casing of the ribbon cassette in preparation for use thereof.
