Abstract
Independent control by a single motor of two members mounted on a shaft, e.g. print wheels in a printing machine such as a postal franking machine, is enabled by having the first member either fixed in rotation to the shaft or connected to the shaft by a one-way clutch, and having the second member connected to the shaft by a one-way clutch, the arrangement being such that rotation of the shaft in one direction causes movement of the first member only (by direct drive or by the action of the associated clutch) and rotation of the shaft in the other direction causes movement of the second member only, by the action of the associated clutch.
