Receiving unit for a data card containing an electronic circuit

Claim 1

Receiving unit for receipt of a data card containing an electronic circuit for an apparatus to be put into operation by means of the data card, said receiving unit having a push-in frame with a receiving compartment therein for the data card, said frame being pivotable between an input/output position and an operating position in which the receiving compartment is inaccessible and in which contact elements of the receiving unit, through an opening in the push-in frame, rest against contact elements of the data card, locking means for fixing the push-in frame in its operating position and biasing means for biasing the push-in frame to the input/out position; said receiving unit comprising: a face plate having an input/output slot therein for receipt and discharge of said data card, said push-in frame being positioned behind said face plate with said receiving compartment aligned with said input/output slot when said push-in frame is in the input/output position so that said card can be inserted into said push-in frame through said input/output slot; an elastically deflectable restoring unit arranged in said receiving compartment opposite said face plate biasing said data card in the direction of said face plate; a catch projection fixed to said face plate a spaced distance from said input/output slot, said catch projection overlapping said data card when said push-in frame is pivoted to said operating position to retain said data card in said operating position, said elastically deflectable restoring unit biasing said data card under said catch projection to maintain said overlap for keeping said data card in said operating position; an opening in said face plate extending through said face plate and catch projection, said opening being adjacent said data card when said push-in frame and data card are in said operating position, said data card being accessible through said opening to be pushed against said elastically deflectable restoring unit to move said data card away from said catch projection to thereby release said data card and said push-in frame being biased to said input/output position, said elastically deformable restoring unit biasing said data card into said input/output slot upon reaching said input/output position.
