Abstract
The present invention pertains to the problem of decollating the lowest card 3 of a stack 2 of cards guided in a shaft 1 without giving rise to a considerable friction between the card surfaces. This problem, which arises especially in the case of plastic cards designed as printed data storage media, is solved by the present invention by the lowermost card 3 being located with its front 4 and rear 5 edges between two push-off members 6, 7, which are mounted rotatably around two mutually parallel axes 12, 13. The lowermost card 3 is first pushed off to the rear 8 by a small amount, and it is at the same time spaced from the card located above it, after which the front edge 4 of the card is released and is freely movable in the downward direction. The lowermost card 3 is then pushed off in the opposite direction 9, and it reaches a conveyer in an oblique free fall.
