PURPOSE:To align a thin long-sized body like a leak frame with high accuracy by hanging a positioning member with its pressing at near necessary position onto the positioning means for a long-sized body and after positioning the long- sized body to the necessary position with moving it by a trace amount transferring the long-sized body. CONSTITUTION:A lead frame 4 is intermittently transferred until the distance B slightly shorter than the regulated transfer distance by a transfer means 9. The space from B up the regulated transfer distance point A is taken as the position where the tip of a pilot 1 is caught by the tip of a pilot hole 2 by descending the pilot pin 1 with a micro-aircylinder 5 and the lead frame 4 is transferred for trace distance with pressing the tip of the pilot pin 1 to the lead frame 4. When transferred up to the regulated transfer distance point A, the pilot pin 1 comes completely into the pilot hole 2 and further comes in the escape hole 3 of a load frame supporting base. In this case the invagination of the pilot pin 1 is detected by a photoelectric switch 7 and the alignment is completed.
