<p>A device for randomly generating numbers and/or codes, and having a number of sheet elements (3) stacked to form a pack structure (4); and a retaining and covering device (7) preventing the pack structure from being opened and/or relative displacement of the sheet elements (3), and only permitting sequential extraction, one by one, of the sheet elements at one end of the pack structure (4). At least some of the sheet elements (3) bear a randomly generated ~number and/or a symbol on a face facing inwards of the pack structure (4).</p> |
