Abstract:
1. An electric-component mounting system for mounting electric components on a circuit substrate, comprising: a circuit-substrate holding device operable to hold said circuit substrate; a feeder holding device which holds a plurality of feeders each operable to feed said electric components in a row to a component-supply portion thereof one after another, such that the electric components are fed by each of said feeders in a feeding direction parallel to a first straight line on a reference plane parallel to a component-mounting surface of said circuit substrate as held by said circuit-substrate holding device, and such that said component-supply portions of the feeders are arranged in a direction parallel to a second straight line on said reference plane, which second straight line intersects said first straight line; a movable member which is movable in said reference plane and which holds a plurality of nozzle holders for holding said plurality of suction nozzles, respectively, such that said nozzle holders are arranged in said direction of arrangement of said plurality of feeders and such that each of selected ones of said plurality of nozzle holders is rotatable about an axis of rotation thereof perpendicular to said reference plane, each of asid selected ones of said plurality of suction nozzles including a fixing portion at which the suction nozzle is held by the the corresponding nozzle holder, and a sucking portion which is operable to hold the electric component and which is excentric with respect to said axis of rotation of said each nozzle holder; a spacing-distance adjusting device operable to adjust a distance between the sucking portions of adjacent ones of said selected ones of said plurality of suction nozzles in said direction of arrangement of said plurality of feeders, said spacing-distance adjusting device including a plurality of nozzle-holder rotating devices operable to rotate said selected ones of said nozzle holders independently of each other to respective desired angular positions thereof; and a component-holding control device operable to control said plurality of nozzle-holder rotating devices of said spacing-distance adjusting device, for adjusting a relative position in said direction of arrangement of said feeders, between each of said selected suction nozzles and the electric component located in said component-supply portion of the feeder corresponding to said each selected suction nozzle, so as to permit said sucking portions of said selected suction nozzles to simultaneously hold by suction the respective electric components located in the respective component-supply portions of the feeders corresponding to said selected suction nozzles.
