Abstract
A contact frame for an IC card reader including contact elements for making connections with the IC card, the contact frame further including two electric contact blades (26, 28) carried by said frame and constituting an end-of-stroke contact (5), with one of said blades, a "fixed" blade (28), being coupled to the frame in such a manner that its stationary position relative to the frame is defined, while the other blade, a moving blade (26), is urged by a resilient force in a direction opposite to the direction in which a card is inserted into the reader, and is disposed in such a manner that a card being inserted comes into abutment thereagainst and imparts actuating motion thereto against its resilient force.
