This invention provides a monitor area setting device with which an area can be easily added to or deleted from a monitor area. The device includes: an area addition/deletion specifying unit that specifies an addition area and a deletion area based on an input signal from an operating unit; an inconsistent area extraction unit that extracts an area that is between the safety area and the addition area with respect to the safety sensor as an inconsistent area; and an area setting update unit that updates area setting information so as to set an area formed either by adding the addition area and the inconsistent area to the safety area or by excluding the deletion area and the inconsistent area from the safety area as a new monitor area.
