The present invention enables cleaning to be performed more reliably when performing cleaning as a countermeasure against contamination. In the present invention, when, for example, a person touches the portion of a desk 91 set in a room R indicated by reference sign 1A, a control device 60 specifies the touched section as a specified section 80 contaminated by a person. In this situation, the control device 60 then controls a drive mechanism 30 to direct a light source 20 at the specified section 80. The locations in the room R touched by a person are thereby irradiated with UV light to sterilize the locations touched.
