Then another pressing pin 15X is moved until it comes into contact with the right longer side of the substrate 5 by driving an X-direction pressing mechanism 16X and the position of the longer side is detected. By comparing the detected position of the longer side in X-direction with a prescribed coordinate position, the difference between the two positions is found as a positional deviation to be corrected. Then the substrate 5 is positioned to a prescribed position by driving a moving table based on the positional deviation. Even at the time of positioning a substrate to be positioned in a horizontal position which is obtained by turning the above-mentioned position by 90 deg., the substrate can be positioned by a similar sequence.
