Abstract
An antenna drive apparatus having a drive control unit and an antenna connected to the drive control unit via first and second connecting lines, and driven by an AC signal at a first resonant frequency, includes: a first driven member connected to the drive control unit via the connecting lines and driven by the AC signal at a second resonant frequency; a sensing member connected to the drive control unit via the connecting lines and driven by a DC signal, capable of sensing approach or contact of a person and, outputting a sensing signal indicating the fact that the approach or the contact has been sensed to the drive control unit via the first connecting line; and a stop mechanism configured to stop a function of the sensing member when the AC signal supplied to the antenna or the first driven member is sensed.
