ABSTRACT:
A device for the exchange of information with an electronic memory card which can be placed into a read position in the device through an insertion opening along an insertion track, in which position electrical contacts of the memory card are in contact with electrical contacts of the device provided on a carrier which is displaceable transversely to the insertion track. In the absence of the memory card, the contacts are situated in the insertion track under the influence of a pretensioning force. The carrier has an abutment surface which extends obliquely relative to the insertion track so that the carrier can be displaced out of the insertion track by the memory card against the pretensioning force during the passage of the memory card. In the read position of the memory card, accordingly, the carrier is in a position which is adapted to the thickness of the memory card, so that the device is suitable for cooperating with memory cards of various thicknesses. The device may be used, for example, in a car radio for cooperating with a safety card protecting against theft of the car radio. In a special embodiment, the device is fastened to a printed circuit board of the car radio, the carrier being arranged in an opening in an upper plate of the device and in an adjoining further opening in the printed circuit board, so that the compartment space required by the device in the car radio is negligibly small.
