Abstract
Abstract A device for the processing of account cards, magnetic account cards or the like in accounting machines, electric typewriters and similar apparatus comprises a gridlike drum for the admission and extraction of a card to and from a circular guide track and for guiding it therein. The guide track for the card is delimited internally by a number of spaced rigid guide rings mounted on a drum main shaft and externally by deflectors distributed over the periphery of the drum and pivoted one on either side of each guide ring to longitudinal bars so that always two neighboring deflectors are angularly displaced. The longitudinal bars are distributed over the periphery of the drum and one end face of the drum consists of a rigid plate, driving rollers and counterpressure rollers being provided in the vicinity of said rigid plate, in the zone of said guide track.
