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. |
