る帯状物の検出装置。 A device that detects the widthwise edge of a moving strip using a brightness detector includes a brightness detector that detects the brightness of the strip and the background, and a device that detects the edge of the strip based on the brightness signal from the detector. It is equipped with a signal processing device that has the function of calculating the position and storing brightness difference data at multiple points at the edge position, and changing the judgment reference value for judging the edge position based on this, and inputting the data to the brightness detector. 1. A belt-shaped object detection device characterized in that the edge position can be detected even when the brightness decreases by changing the edge position determination reference value accordingly.
