<p>A challenge to be met by the present invention is to provide an electronic component mounting machine and an electronic component loading head in which the loading head has two rows of nozzle shafts and that can promote miniaturization of the machine by minimizing the loading head. In a loading head having two rows of nozzles (L1 and L2) including a plurality of nozzle shafts arranged in rows and at a predetermined nozzle arrangement pitch, aθrotary drive mechanism that rotates the nozzle shafts around their axes is configured so as to include driven pulleys (28) coupled to the respective nozzle shafts; a plurality of idlers (30) interposed between the two rows of nozzles (L1 and L2); and endless drive belts (29A and 29B) that transmit rotation of theθ-axis motors (27A and 27B) to the driven pulleys (28). Drive surfaces (29a) of the respective driving belts (29A and 29B) are looped around the respective drive pulleys and the respective driven pulleys, and the other sides of the respective drive surfaces (29a) are looped while guided by the idlers (30).</p> |
