PURPOSE:To accelerate the lead positioning process by a method wherein the interval of at least 2 each of leads out of multiple leads is measured to calculate the ratio of interval to reference value so that the positions of any other leads may be decided by correction using proportional distribution. CONSTITUTION:n each of leads are arranged in the total distance at the interval of l1-ln. When the distance from the first to the last lead is detected to be l+ l, the error l distributing the total is assumed to be l1'1=(l+DELTAl)l1/l,..., ln'=(l+DELTAl)ln/l. Through these procedures, the positions of leads can be detected by detecting arbitrary 2 each or 4 each of positions not necessarily detecting the positions of the first and the last lead.
