ABSTRACT:
An endless ink ribbon cassette wherein a ribbon is drawn from a storage void for printing and reintroduced into the storage void after printing. The cassette includes a first driven induction wheel having first and second rim portions spaced apart on an axle. A second idler induction wheel, also mounted on an axle, is urged against the rim portions, the first and second induction wheels cooperating to draw the ribbon onto the first induction wheel and between the first and second induction wheels, whereby the ribbon is introduced into the storage void. A fixed insert maintained between the first and second rim portions prevents entry of the ribbon between the first and second rim portions.
