PROBLEM TO BE SOLVED: To allow a paper sheet identifying device to identify a valuable paper sheet which is current only in the game hall instead of paper money. SOLUTION: This valuable paper sheet 50 has a specific pattern printed invisibly at the position corresponding to the paper sheet sensor of the paper sheet identifying device and can be inserted into the paper sheet identifying device. When the valuable paper sheet 50 is inserted into the paper sheet identifying device, the country code, amusement place name, value rating, start/stop information, test mode, and version information can be identified from the specific pattern printed on the valuable paper sheet 50 to prevent the valuable paper sheet from illegally being used and lighten the burden on an administrator. |
