PROBLEM TO BE SOLVED: To solve problems of a conventional method that two sets of cords and AC adaptors have been required because two separate power supplies for an electronic apparatus and a wireless transmission/reception apparatus and wasteful power has been consumed because the power supply of the wireless apparatus is left unswitched even when a power switch of the electric apparatus is switched off in the case that the wireless transmission/reception apparatus is connected to the outside of the electric apparatus to make the electric apparatus having no wireless communication function wirelessly communicationable. SOLUTION: The wireless transmission/reception function is mounted on the AC adaptor used for the electric apparatus to unify cords for the power supply and data communication and to make conventional ports of the electric apparatus available without any modification. Thus, having only to replace the conventional AC adaptor with the AC adaptor disclosed herein can make the electric apparatus wirelessly communicationable without the need for direct connection of the wireless transmission/reception apparatus to the electric apparatus.
