PROBLEM TO BE SOLVED: To quickly mount parts through re-supply of the parts when the supplied parts are defective and mounting the parts via a transfer operation. SOLUTION: For enabling a working device to repeat mounting of supplied parts via a transfer operation only when the parts are non-defective and mounting next substituted parts after waiting for the supply of the next substitution parts by disposing defective parts if they exist, the same type of parts are transferred for each of a plurality of parts-retaining parts located at a parts- transferring table, and the remaining parts of the same type being located at the parts-retaining part on the parts-transferring table are supplied to the working device again for mounting the parts when one type of parts is supplied to the working device and the parts are judged to be defective and are disposed by the working device, thus achieving the above purpose. |
