Abstract
A laser area sensor includes a laser range finder, a scanning mechanism that changes a measurement direction of the laser range finder, and a distance data acquiring portion that defines a detection area and acquires distance information in each direction in the detection area in a time-series manner, by periodically causing the laser range finder to perform measurement while causing the measurement direction to be changed. The laser area sensor also includes a human body judging portion that extracts a portion that is presumed to correspond to a human body, from among the distance information and judges whether or not the extracted portion matches a human body based on a time-series moving status of the extracted portion, an alert output control portion, a memory, and a DIP switch.
