CONSTITUTION:A first projection 5 for preventing the coming off of a unit by engaging it to a first groove 6 of a conforming power source unit 2 if formed in a unit housing 4 of a game machine main body 1 which is an electric apparatus, and in addition a second projection 9 is formed. A second groove 10 for locking to the second projection 9 to electrically connect terminals is formed in the conforming power unit 2. The second groove 10 is not formed in a power source unit which is not conformed with the game machine main body 1, or a shorter groove than the groove 10 is formed to prevent the connection of the game machine main body 1 with the power source unit 2. |
