Patent ID: 7673798

Claim:
Push/pull card reader for contacting electric contact fields of a card inserted into the card reader, the contact fields being provided at the same flat side of the card comprising a first row of parallel electric contacts and a second row of parallel electric contacts in the form of elastically deformable contact springs for contacting the electric contact fields of an inserted card wherein one row is disposed behind the other row in the card insertion direction and at the same flat side of the inserted card, wherein the contact springs extend parallel to a card insertion direction and wherein each contact spring comprises a contact section projecting into a 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, wherein the sections of each contact spring are provided at the same side of the card path wherein the contact section, the U-shaped joining section and the mounting section are symmetrical relative to the center plane of the contact spring and wherein the U-shaped joining section of each contact spring of one contact row is formed by two parallel U-shaped arms which are spaced apart in a transverse direction and extends from the mounting section in a direction opposite to the card insertion direction, and the connecting section of each contact spring of the one contact row extends from the mounting section between the two U-shaped arms in a direction opposite to the card insertion direction.
