Abstract
A card reader has a guide channel followed by a connector and it includes a cradle pivoting about a stationary axis, a roller whose axis is parallel to the stationary axis being mounted in the cradle with freedom to move in translation along a direction .increment. perpendicular to the roller axis, said direction .increment. being at an acute angle .alpha. to the direction in which the guide channel extends, the cradle including resilient return means urging the angle .alpha. to close and drive means acting on command and of greater power than said return means to urge said angle .alpha. to open. The roller includes resilient means urging it along the direction .increment. towards the vertex of the angle .alpha.. When the reader is in the rest position, the roller obstructs said channel, when a card is fully inserted in the reader, at least a portion of the card remains outside the reader, the cradle being in abutment in a position where the angle .alpha. is less than the angle .beta. whose tangent is equal to the coefficient of friction .mu. between the roller and the card. The drive means are powered after the card has been processed so as to open the angle .alpha. and enable the card to be withdrawn.
