Abstract

A chip card reader is disclosed with carriages (2) mounted in a receiving part (1) for displacement counter to a spring force. A feature of the present invention is that the present chip card reader exhibits high contact forces and at the same time low card insertion forces. The carriage (2) carries contact springs (14) for the contacting of the chip as well as a device (11, 16) for turning the reading and evaluating system on and off, where the control of these two systems occurs through a slide (7) which is disposed in the carriage (2) crosswise to the direction of card introduction, and which is actuated by at least one control surface (8, 9) disposed in the receiving part.
