Abstract
A film ribbon cassette for an impact printer is disclosed. The cassette includes two compartments (430 and 432) divided by a central wall (434). A central shaft (482) extends from compartment (432) into the other compartment where it receives a motor drive (486). The shaft is attached to a knurled roller (472) which draws the ribbon from the supply spool (438) through a member (436) across an aperture for a printing station, crossing over and returning to the other side of the cassette into the spent ribbon compartment (432).
