A device controller is provided which allows a vehicle occupant to confirm a device to be operated without looking an operation section. When a controller of a microswitch indicates a device such as a window regulator or a sun roof, a control circuit feeds a motion confirmation signal to a corresponding device such as a right-hand front door ECU and a roof ECU. A door glass, a sliding roof or the like then reciprocate slightly (i.e., in an amount that is enough for the vehicle occupant to visually confirm the reciprocation) via a window regulator driving circuit, a sun roof driving circuit or the like. The vehicle occupant can thereby confirm a device to be operated by the operation section without looking an operation section.
