Another aspect of the invention concerns the provision of a daisy wheel petal guide (22) between opposed ends (20 and 18) of two arms (12 and 14) of the cassette which in part define a ribbon path with the ribbon stretched across the gap.
The invention also includes a typewriter which is adapted to receive a cassette having the above characteristics and which includes an actuator 112 in the typewriter for engaging the arm 36 to move the ribbon guide as required.
