Abstract

An electric-component mounting system including component-mounting devices arranged in an array and each having a component-holding head for holding an electric component, and a head-moving device to move the head, and a substrate-transferring device to move at least one substrate on which electric components are to be mounted, and wherein the substrate-transferring device stops each substrate at at least one stop position which corresponds to at least one of the component-mounting devices and at which operations of the component-mounting devices are concurrently performed on the at least one substrate. The substrate-transferring device includes a first transferring device to move each substrate along a path parallel to the array of the component-mounting devices and stop each substrate at least once during its movement along the path, and a second transferring device having a substrate-holding device to hold each substrate at each stop position and a holding-device moving device to reciprocate the substrate-holding device by a maximum distance smaller than a maximum distance of movement of each substrate by the first transferring device, so that each substrate is moved together with the substrate-holding device.
