向きである。On the other hand, remote control devices using ultrasonic waves and near-infrared rays have recently been put into practical use in the field of television, but these methods are also unsuitable for controlling welding output, as is the case with the method described above. In methods using ultrasound,
Malfunctions may occur due to ultrasonic noise generated by the impact sound of iron plates or metal, and methods that use near-infrared rays can be used within a short range of several meters (approximately 7 meters or less) in an ordinary household, and even when the target object is This method is not suitable for cases where the object needs to be operated from a location that is more than ten meters away (30,771 meters in the case of long distance) from the visible location.
