A device for releasably securing a magnetic, electronic or optical read and/or write head to a card or ticket transport system, comprises a resilient frame (1), a carriage (2) for the head, and mounting means (4, 5) for mounting the carriage on the frame, the mounting means comprising a pair of rolling element bearing axially loaded by the restoring force of the resilient frame. The carriage is pivotally moveable about a first axis (7) parallel to the direction of transport of any ticket and not pivotally moveable in the direction of transport. The device may further comprise a magnetic head (3) in a resilient housing (12) and biasing means (11), the head being pivotally moveable about a second axis (6) substantially parallel to the first axis. In operation, the biasing means biases the magnetic head towards any card or ticket.

La présente invention concerne un dispositif permettant de fixer de manière amovible une tête de lecture et/ou d'écriture magnétique, électronique ou optique à un système de transport de carte ou de ticket. Ce dispositif se compose d'un cadre élastique (1), d'un chariot pour la tête et d'organes de montage (4, 5) permettant de monter le chariot sur le cadre, ces organes comportant une paire de coussinets d'éléments roulants bloqués axialement par la force de rappel du cadre élastique. Le chariot peut se déplacer par rotation autour d'un premier axe (7) parallèle à la direction de transport de tout ticket mais il ne peut pas pivoter par rapport à la direction de transport. Le dispositif peut, en outre, comporter une tête magnétique (3) dans un boîtier élastique (12) et un organe permettant le déplacement oblique (11), la tête pouvant se déplacer par rotation autour d'un second axe (6) sensiblement parallèle au premier. En cours de fonctionnement, l'organe permettant le déplacement oblique déplace obliquement la tête en direction de tout ticket ou toute carte.
