发明名称 Locking device for a video game electronic apparatus and method therefor
摘要 This disclosure is directed to a selectively lockable or unlockable video game electronic apparatus for permitting the playing of video games only when the apparatus is unlocked. This apparatus is a video game console that uses a locking device which comprises a housing that is placed at the opening of the game cartridge slot of the video game electronic console or apparatus, thereby preventing entry of a video game cartridge into the console or apparatus, which means that the console or apparatus is locked. The locking device further comprises a key mechanism located within the housing which, when pushed inwardly, moves two spring-loaded locking cams, which have extension portions to permit the locking device to lock or engage within recesses located in an empty video game cartridge opening in the video game electronic console or apparatus. The removal of the locking device from the console is impossible until the key is used to retract the locking cams.
