Abstract
Security is ensured by judging agreement with a specific indication, such as a trademark, whose identity is socially recognizable to effectively expel counterfeits from the market. A game machine in which a CD-ROM 17 is mounted on a game machine 10 to play a game based on program information stored in the CD-ROM 17 comprises a recognition sensor 22 reading a trademark indication region 20 on the exterior surface of the CD-ROM 17, and a judging unit judging whether a specific trademark TM is displayed in a trademark indication region, the game based on the program information being prevented from starting, or if started stopped when the specific trademark TM is not displayed.
