Abstract
An electronic device handling apparatus, wherein an image of terminals of an electronic device to be tested having the terminals at its end edge portions held by a conveyor device is taken, edges of terminals arranged in the X-axis direction are extracted from data of an taken image and binarization processing is performed on the data, while edges of terminals arranged in the Y-axis direction are extracted from data of the taken image and binarization processing is performed on the data, so that positions of edges of respective terminals are located from the obtained two binary images. Then, a positional deviation amount of the electronic device is calculated by comparing with reference positional information of edges of terminals of a reference electronic device and, based thereon, a posture of the electronic device to be tested is corrected.
