  • the information code display device 10 according to the present disclosure is provided with a battery, so that even when the power cable is not connected to the outlet, the control unit 11 describes the above according to the power supplied from the battery. Information code display processing may be performed. Even in such a battery-powered system, when the power supply from the battery is stopped, the state in which the information code C is displayed on the screen of the electronic paper 13 is maintained, so that the above effect is obtained.
  • the information code display device 10 is used in a store other than the store where the information code display device 10 is originally installed. If so, it is possible to call attention by using the display or the like on the display unit 24. As a result, unauthorized use of the information code display device 10 in a store that is not originally used can be prevented, and security can be improved.

Abstract

L'invention concerne un dispositif d'affichage de code d'informations (10) qui affiche, sur un terminal portable, un code d'informations à lire. Le dispositif (10) comprend : une unité d'affichage pourvue d'un papier électronique (13) ; et une unité de mémorisation (12) dans laquelle est mémorisée une pluralité de codes d'informations pour lesquels une période efficace est établie. Le dispositif (10) comprend en outre : une unité de commande d'affichage (11) qui commande l'état d'affichage du papier électronique (13) ; et une unité de source d'alimentation électrique (16) qui fournit de l'énergie électrique à l'unité de commande d'affichage (11). Parmi ceux-ci, l'unité de commande d'affichage (11) reçoit une alimentation en énergie électrique provenant de l'unité de source d'alimentation (16). Selon cette énergie électrique qui est reçue, l'unité de commande d'affichage (11) commande le papier électronique (13) de façon à afficher, parmi la pluralité de codes d'informations mémorisés dans l'unité de mémorisation (12), un ou plusieurs codes d'informations dans la période efficace.
