摘要： A card reader comprises two rows of electric contacts in the form of elastically deformable contact springs for contacting the electric contact fields of a card inserted into the card reader, wherein the contact springs extend parallel to the card insertion direction and wherein each contact spring comprises a contact section projecting into the card path for contacting one of the contact fields of the card, a connecting section for connecting to a write/read device, an intermediate U-shaped joining section, and a mounting section for mounting the contact spring to the card reader housing, all being formed in one piece with the contact spring. In accordance with the invention, the contact section, the U-shaped joining section and the mounting section are symmetrical relative to the center plane of the contact spring.

摘要： 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).
