Abstract

Selon l'invention, il est déterminé (S5) si une carte SD a été introduite ou non. Lorsqu'il est déterminé qu'une carte SD a été introduite, une lecture de données sur la carte SD est alors exécutée (S6). Il est déterminé (S6#) si des informations d'espace de travail sont contenues ou non dans les données obtenues par la lecture des données sur la carte SD. Lorsqu'il est déterminé que des informations d'espace de travail sont contenues dans les données obtenues par la lecture des données sur la carte SD, des données d'espace de travail sont générées sur la base d'informations de commande d'espace de travail (S7).
