Abstract: In accordance with the invention, in a card reader comprising a pivot arm that engages behind an inserted card, a locking element that can be displaced in the insertion direction of the card and, in a locking position, blocks a pivoting motion of the pivot arm out of the engaging pivot position, a toothed wheel which is driven by a pinion and on which the locking element eccentrically engages, and at least one stop face that cooperates with the card reader for limiting the rotation of the toothed wheel, the at least one stop face is provided on the pinion.

Abstract: 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.

Abstract: In accordance with the invention, in a card reader (1) comprising a pivot arm (4) that engages behind an inserted card (2), a locking element (8) that can be displaced in the insertion direction (3) of the card (2) and, in a locking position, blocks a pivoting motion of the pivot arm (4) out of the engaging pivot position, a toothed wheel (13) which is driven by a pinion (15) and on which the locking element (8) eccentrically engages, and at least one stop face (17; 18) that cooperates with the card reader housing (20) for limiting the rotation of the toothed wheel (13), the at least one stop face (17; 18) is provided on the pinion (15).

Abstract: In accordance with the invention, a card reader (1) comprising a contacting unit (2) for a card (4) that can be inserted through a card insertion opening (6), comprises on its mounting side (7) a conductor path element (8) that can be bent against the action of an elastic restoring force and comprises two exposed electrical contacts (9a, 9b), and the bendable conductor path element (8) can be bent between its two exposed contacts (9a, 9b) until the two exposed contacts (9a, 9b) abut each other against the action of the elastic restoring force in an electrically conducting fashion.

Abstract: In accordance with the invention, in a card reader for data exchange with a card that stores data, exposed electrical contacts of the card reader, via which the exchanged data is transmitted in an uncoded fashion, are covered by a cap, and a switch covered by the cap is triggered by removing the cap.

Abstract: In accordance with the invention, in a card reader (1) comprising a contacting unit (2) for a card (3) that has been inserted through a card insertion opening (5), the contacting unit (2) is disposed in a pocket (6) which is open at the card insertion opening (5) and has a fine-meshed conductor path structure with at least one continuous conductor path (9), and is formed from at least one conductor path foil (7) by mutually overlapping sections, wherein the overlapping sections comprise conductor path ends which are interconnected in an electrically conducting fashion to form the continuous conductor path (9), and wherein one pocket side that forms the bottom (8) of the card reader (1) has a recess (10) for contacting the contacting unit (2).

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).
