知範囲が制約される。Conventionally, as a method for intermittently guiding infrared rays to an infrared detection sensor, there is a vane type in which multiple blades are rotated in front of the detection frontage of a sensor unit containing an infrared detection sensor. Because the drive mechanism is placed on the side of the detection opening of the sensor unit and the blades are placed on the front of the sensor unit, the sensor unit is large in the width and height directions. Place the vibrator facing the detection window and rotate the vibrator at the required period. There is a vibrating type that closes, but since these mechanisms are installed on the top of the infrared detection sensor, even if you try to install a reflector body that guides infrared rays to the infrared detection sensor, it will not be possible to install it because of the presence of those mechanisms. The detection range of the infrared detection sensor is restricted.
