<p>PROBLEM TO BE SOLVED: To provide a safe and comfortable working environment using a human body detector for detecting human body especially in the working area of a mobile body, concerning a human body detection sensor using an infrared sensor. SOLUTION: An infrared sensor 11, in which plural photodetecting parts detect respective areas, is installed on the mobile body, an output for every area provided from this infrared sensor 11 is sent to the human body detecting means 12, and it is judged whether a human body exists or not. The information of the judged result is sent to an interlocking device 13, and an alarm is issued to worker, or when the existence of the human body in this area is detected, the mobile body is forcedly stopped.
