PROBLEM TO BE SOLVED: To provide an electronic apparatus for raising power when an external optional apparatus is added with a simple structure. SOLUTION: A capacitor 202 is arranged on an external optional apparatus 200-side. The capacitor 202 on the optional apparatus 200-side is charged through a power converter 101 except for the time when the power converter 101 is operated at maximum power. Thus, it is not necessary to mount a large and expensive private power circuit on the optional apparatus 200-side without raising power capacity in adding the optional apparatus 200.
