Abstract: A method for mounting electronic parts on a printed board using a computer, an optical indicator controlled by the computer to optically indicate a position of insertion on the printed board into which an electronic part is to be inserted, and a parts locator having a plurality of pockets and controlled by the computer to rotate and open only one pocket is disclosed. Parts taken out at random from a parts box are put into opened pockets of a parts locator, or after the parts are inserted into the positions of insertion on the printed board indicated by the optical indicator, the remaining parts are put into the opened pockets of the parts locator. Subsequent mounting work can be performed only by taking out the parts from the pockets of the parts locator and inserting the parts into the optically indicated positions.
