Abstract (en)
[origin: US4491430A] A ribbon cassette includes an impeller actuating element mounted at the end of a ribbon guide roller. A feed reel, on which the ribbon is mounted, rotates the guide roller, by means of the ribbon, and is mounted so as to be displaceable relative to the guide roller. The ribbon continues to rotate the guide roller as it is transported from the reel. When the remaining ribbon is at a specific length, the core of the reel halts the impeller, thereby discontinuing signals in a scanning device. Nevertheless the remaining ribbon can still be unreeled from the feed reel. The scanning of the movement of the impeller can be carried out by using a sensing mandrel attached to a spring member.
