    • PROBLEM TO BE SOLVED: To avoid contact between terminals if wrong mounting of an analogous mounting component to a body side equipment should be done. SOLUTION: A video camera (the body side equipment) 1 has a body side terminal 30, while a battery pack (the mounting component) 100 has a battery side terminal (mounting component side terminal) 120 jointing to the body side terminal. A discriminator 111 is formed in the neighborhood of the battery side terminal (mounting component side terminal) 120 and at the same time a blocking part 19 which determines whether the mounting can be done by combination of uneven fitting to the discriminator is formed in the neighborhood of the body side terminal of the video camera (body side equipment). When the mounting is determined not to be done by interference of the blocking part and the discriminator, electrical connection between the body side terminal and the battery side terminal (mounting component side terminal) is prevented to be done.
