Zusammenfassung:PROBLEM TO BE SOLVED: To shorten process time required for calculating a lead rise amount for faster mounting tact by univocally setting a first candidate point of a lead position information from the lead position information, and univocally obtaining, likewise, second and third candidate points among the lead position information except for that candidate point. SOLUTION: Based on each lead position information of a lead 1a of an electronic component 1, a lowest lead position information is selected to firstly decide a first candidate point. Then, by rotating a plane comprising the decided first candidate point around a rotation axis, a lead 1a contacting the plane first is obtained and the lead position of the lead 1a is decided as a second candidate point, and a third candidate point is obtained likewise, then, the plane formed of the first-third candidate points is judged to satisfy a condition for concluding a virtual plane. Thus, the calculation frequency in virtual-plane calculating operation is first-power order of the number of leads, resulting in significantly reduced the number of calculations for faster calculation.
