Abstract: PURPOSE: To enable the accurate mounting of parts on a circuit board by correcting the angle deviation of parts from a reference line at sucking or the positional deviation of the center of the parts from the suction center of a nozzle in a simple constitution. CONSTITUTION: Moving and rotating of a suction nozzle 16 are repeated until one side of parts 14 parallelly touches a parallel zone 21 generated by a laser identification sensor 15.

The obtained angle deviation and positional deviations are corrected to mount the parts. Thus, these deviations can be corrected in a single constitution and accurate mounting of parts on a circuit board can be made.
