Abstract
A device for improving a system for controlling the winding of a ribbon on a take-up reel. This device is particularly designed to obviate the phenomenon of clinging between a ribbon and the face of a card to be printed on, during an operation of printing by the thermal transfer of inks carried by the ribbon. For that purpose, the vertical shift of the ribbon is detected by a sensor associated with an optical detection device. The detection of this shift prompts the modification, in a circuit, of the number of steps per time unit of the step motor.
