Abstract: In a card reader (40) with at least two transport rollers (23, 24, 25) for the card (3) arranged one after the other in the card infeed direction, the transport rollers (23, 24, 25) are provided on a pivot arm (21, 22), which can be pivoted against the action of a restoring force in a plane at right angles to the card path, at a distance from the pivot axis (26, 27) of the pivot arm (21, 22). When a transport roller on the pivot arm is deflected by the card thickness of a card that has been fed in, all transport rollers lying further from the pivot axis are also deflected, i.e. pivoted out of the card path, by more than the card thickness.

Abstract: A card reader (1) with three rollers (4, 5, 6) mounted on pivot arms (10, 11, 12, 13) and which are disposed serially in the direction (2) of card insertion, the pivot arms (10, 11, 12, 13) being pivotable in a plane at right-angles to the card path against the action of a restoring force and being coupled to one another for movement, the roller (4) which is at the rear in the direction (2) of insertion being disposed on a rear pivot arm (10) behind its pivot axis (15) while the roller (6) which is at the front in the direction (2) of insertion is disposed on a front pivot arm (13) in front of its pivot axis (16), comprises two middle pivot arms (11, 12) which are articulatingly connected to each other, one middle pivot arm (11) being disposed at a distance from its pivot axis (17) with the rear pivot arm (10) while the other middle pivot arm (12) is articulatingly connected to the front pivot arm (13) at a distance from its pivot axis (19).

Abstract: In order to assure a reliable insertion into the data exchange position even of cards with strongly bent downwards surface in longitudinal direction for a card reader (1), into which a data storage card (2) can be inserted for information exchange, with a card guide (4,5) which guides the card (2) approximately horizontally into its data-exchange position, which card guide is interrupted downwards in a section in the direction of insertion (3), the length (L) of said interrupted section is less than the normal card length, and with a drop opening (8) for cards (2′) of shorter length than normal cards (2) provided beneath the interrupted section (7), where when in the data exchange position, the front end (2a) of the card rests against a support (11) in the card reader (1), a stopping segment (15) extends, counter to the direction of insertion (3), from the support (11) to beneath the interrupted section (7) of the card guide.
