Abstract: PURPOSE:To stabilize the size of circuit pattern printed on a mask regardless of any atmospheric change by a method wherein a processor receiving detection signals from three detectors to calculate the air density from the inputted data on the detection signals as well as an output means to output the objective distance signals corresponding to the air density are provided.

The data processed by the processor 14 are inputted to an output means 15 outputting objective distance signals to a vertical actuator 9. Under low atmospheric pressure, the air density in a space 6 declines to change the optical path as shown by broken arrow lines. However, the detection signals from an atmospheric pressure detector 11 decline to reduce the objective distance signals transmitted from the output means 15 to the vertical actuator 9 through the processor 14 so that the distance from a transparent original 3 to a convex lens 4 may be shortened to make the size of circuit pattern printed on a mask sheet 5 unchanged as compared with the size under normal atmospheric pressure.
