1. An electronic-parts mounting apparatus comprising:
- an electronic-parts feeder;
a mounting head for carrying electronic parts from the electronic-parts feeder, the mounting head including a plurality of nozzles for respectively holding the electronic parts;
an electronic-parts mounting portion for enabling the plurality of nozzles of the mounting head to mount the electronic parts on a circuit board;
first means for effecting movement to rotate said nozzles about axes of said nozzles respectively and thereby rotate the respective angular positions of said nozzles equally; and
second means for moving each of the nozzles upward and downward;
wherein the first means includes a pinion provided on an outer circumferential surface of each of the nozzles, and a rack meshing with the pinion.

Abstract
An electronic-parts mounting apparatus includes an electronic-parts feeder. A mounting head operates for carrying electronic parts from the electronic-parts feeder. The mounting head includes a plurality of nozzles for holding the electronic parts respectively. An electronic-parts mounting portion operates for enabling the mounting head to mount the electronic parts on a circuit board. A first mechanism operates for rotating each of the nozzles. A second mechanism operates for moving each of the nozzles upward and downward. The first mechanism may include a pinion provided on an outer circumferential surface of each of the nozzles, and a rack meshing with the pinion.
