An elevator system inspection device classifies each of all sections of an adjacent unit into one of a "section that can be inspected," a "section that cannot be inspected," and a "section for which possibility of inspection is undetermined" and classifies each section for the unit to be run that had been classified as either a "section that can be inspected" or a "section for which possibility of inspection is undetermined" as either a "normal section," an "abnormal section," or an "undetermined state section" by way of inspecting a specific unit and the adjacent unit by controlling the travel of a car of a unit to be run and causing the car of the unit to be run to travel. When controlling the car of the unit to be run, the device controls the travel of the car of the unit to be run so that same travels in a "section that can be inspected" and a "section for which possibility of inspection is undetermined" and to not travel in a "section that cannot be inspected."
