PURPOSE:To enhance a part feed operation in efficiency when parts run out in an electronic part mounting method where electronic parts are automatically mounted on a circuit board so as not to lessen a part mounter in operation rate. CONSTITUTION:When electronic parts run out while electronic parts fed from a feed section 3a are mounted on a circuit board by a mounter 1, the electronic parts concerned are changed in part feed position to an auxiliary feed section 3b through a part feed position changing means, and the mounter 1 is stopped at the time when all the kinds of electronic parts are changed in part feed position to the auxiliary feed section 3b, and all the kinds of electronic parts are replaced at the same time, whereby the mounter 1 can be made to keep mounting without stopping even if parts of a kind out of parts of various kinds run out, so that it can be improved in operation rate. |
