<P>PROBLEM TO BE SOLVED: To provide a game machine for acquiring correct game history even when an operation for determining start or end of a game is not executed. <P>SOLUTION: When finger authentication information does not match finger-authentication registration information before the expiration of a validity period of the game history determined by operating a validity-period setting button, the game machine expires the validity period of the game history and does not display an optical code generated based on game history data. The game machine also starts a new validity period of the game history when the finger authentication information does not match before the validity period of the game history starts. The validity period of the game history for each player can accurately and reliably be determined by checking the finger authentication information even if the player forgets to operate a validity-period-setting-button device. Thus, the player can accurately acquire his/her own game history. <P>COPYRIGHT: (C)2012,JPO&INPIT |
