PROBLEM TO BE SOLVED: To quickly extinguish a fire in the small-scale stage by judging the fire when an ultraviolet sense section senses the fire continuously for a fixed period or an infrared sense section senses the flicker or fluctuation in the movement of a flame, and discharging a fire extinguisher from a nozzle section. SOLUTION: When an ultraviolet sensor 6 senses a fire continuously for nine sec, for example, an operation section 4 is rotated, and a nozzle section 13 constituted of a fire extinguishing nozzle and an infrared sense section 12 is directed to the fire point to detect the portion of the fire. When a small flame is separated by five (m) or above, it is not referred as a fire. When the flame grows to about 30cm×30cm×50cm, the infrared sensor of the nozzle section 13 is operated to measure the width and height of the flame, the nozzle is directed to the center section, and a fire distinguisher is discharged while the nozzle is swayed vertically and horizontally to extinguish the fire. Whether the flame is the flame of a fire or not is judged based on the flicker or fluctuation of the flame, and the flame is not recognized as the flame of a fire when such a phenomenon is not recognized.
