Abstract
A typewriting or printer film ribbon cassette has a carrier with fixedly spaced pins forming axes for the takeup and supply spools so that, as the ribbon builds up on the takeup spool, the carrier is shifted away from a feed wheel whose axis is coplanar with the axes of the supply and takeup spools against the force of a spring urging the carrier in the opposite direction.
