  • Drive coupling
    Patent number: 5149223
    Abstract: A replaceable xerographic cassette is coupled to a rotatable driving shaft in a copying machine by a rotary drive coupling member in which a splined drive shaft of the cassette engages as the latter is inserted into the machine. To accommodate angular misalignment of the shafts, the coupling member is of two-part form and two parts can rotate relative to one another as the shaft is being inserted, to take up any misalignment that may exist.
