Abstract
Perforated information-bearing media in strip form, for example film in cinematographic devices, is driven either intermittently or continuously. The normally used Geneva stop (Maltese cross), which is connected via an output shaft to the sprocket engaging in the film perforations, can be disengaged from the continuously rotarily driven pin disc by axial displacement of either the Geneva stop of the pin disc effected by clutch means. For rewinding or unwinding the film at continuous high speed simultaneously with said clutch-disengagement between Geneva stop and pin disc, clutch members of a continuously driven, on the output shaft axially displaceable and free running clutch disc, engage in the slots or recesses in the Geneva stop at the position of the Geneva stop which corresponds to the frame standstill.
