ABSTRACT:
An apparatus for mounting different sorts of electronic components on a substrate, including a table rotatable about an axis; a plurality of groups of mounting heads supported by the table, each one of the head groups consisting of a plurality of identical mounting heads that differ from the identical mounting heads of each of the other head group or groups, the mounting heads of the each one head group taking an electronic component of a corresponding one of the different sorts from an electronic component supply device and mount the electronic component on a substrate. The mounting heads of the each of the head groups being supported by the table such that the mounting heads of each head group are equiangularly distant from one another on a circle whose center is located on the axis of the table; a drive device for intermittently rotating the table about the axis, the drive device rotating the table by one of a plurality of predetermined rotation amounts for each of the intermittent rotations thereof, the rotation amounts including a rotation amount equal to the equiangular distance predetermined with respect to the mounting heads of each one head group; and a changing device for changing the one of the rotation amounts for one head group to another of the rotation amounts for another head group.
